Abstract:To observe the efficacy of Chinese medicine comprehensive therapeutic project in treating the middle/late stage primary hepatic carcinoma (PHC). With prospective randomized controlled design, 97 patients with PHC were assigned to the test group (49 cases) treated with Chinese medicine comprehensive therapy using Oleum fructus bruceas intervention combining oral intake of Ganji Decoction (肝积方) and external application of Ailitong (癌理通), and the control group (48 cases) treated with chemotherapeutic agents combining iodized oil chemo-embolization and analgesics. The immediate and long-term efficacy, adverse reaction, pain-relieving initial time (PRIT) and pain-relieving sustained time (PRST) of the treatment, as well as the change in relieving patients’ quality of life (QOL) were observed. The difference between the two groups in illness control rate was statistically insignificant (P>0.05), but the adverse reaction occurence rate in the test group was lesser than that in the control group (P<0.05). PRIT was insignificantly different in the two groups (P>0.05), but the PRST was significantly superior in the test group than that in the control group (10.37±2.18 h vs 7.78±1.95 h, P<0.01). After treatment, the increased Karnofsky scores in the test group indicated that the patients’ somatic activity, symptoms and QOL were improved significantly, which were significantly superior to those in the control group (P<0.05). The survival rate in the two groups was similar at the 3rd month after treatment, but the test group did show superiority in terms of half- and 1-year survival rate (65.9% vs 42.5% and 38.6% vs 18.1%, respectively, P<0.05). The median survival time in the test group was 8.9 months and that in the control group was 5.3 months. Chinese medicine comprehensive therapy is an effective treatment for the middle/late stage patients of PHC, and it could extend the PRST, improve the patients’ QOL and long-term survival with less adverse reaction.

Abstract:To observe the clinical combination effect of Jinlong Capsule (金龙胶囊, JLC) and transcatheter arterial chemoembolization (TACE) on the patients with primary hepatic carcinoma (PHC) and JLC’ s influence on serum osteopontin (OPN) expression and elucidate the correlation between the serum OPN level and curative effect of JLC and TACE. A total of 98 patients with PHC were observed in a randomized controlled trial (RCT). They were assigned to the Chinese medicine (CM) group (53 patients who were treated with TACE and JLC) and the intervention group (45 patients who were treated with TACE only). The serum OPN levels were measured before and after treatment by quantitative sandwich enzyme-linked immunosorbent assay (ELISA). Forty healthy people were assigned to the control group. The clinical efficacy was observed and Karnofsky score (KPS) was graded. The clinical efficacy of the CM group (60.38%) was better than that of the intervention group (40.00 %), and the KPS (84.35±12.19) was higher than the intervention group (69.86± 11.58) (P<0.05). The serum OPN levels before and after treatment in the patients with PHC were significantly elevated compared with those in the control group (P<0.01). After treatment, the OPN levels in CM group (117.69 <±78.50) were significantly lower compared with those in intervention group (151.09±83.90, P<0.05). The OPN levels of responders were remarkably lowered than the non-responders after treatment, and the level of OPN in the CM group was lower than the intervention group (P<0.05). The short-term clinical efficacy and the quality of life of patients with PHC can be improved by combining JLC with TACE. The serum OPN levels in PHC patients can reflect the curative effect of treatment and the prognosis of the disease.  
Abstract:To observe the effect of combined therapy with Xuezhikang Capsule (血脂康胶囊, XZK) and Valsartan on left ventricular hypertrophy (LVH) and heart rate turbulence (HRT) in hypertensive patients. Ninety primary hypertensive patients with LVH were randomly assigned to three groups. Basic treatment, including aspirin, β-blockers, calcium antagonists, etc. were administered to all patients. Additionally, Valsartan (VS, 80 mg once a day) was given to the 30 patients in the VS group. Valsartan (in the same dosage) and XZK (600 mg, twice a day) were given to the 32 patients in the Chinese medicine (CM) group, while none was given to the 28 patients in the control group. The therapeutic course lasted for 24 months. Changes in left ventricular mass index (LVMI) measured by cardiac ultrasonic indices, HRT parameters, including the original heart rate (TO) and slope coeffificient (TS), systolic and diastolic blood pressures (SBP and DBP), as well as blood cholesterol level (TC) were measured before and after treatment. After treatment, TO and LVMI were lowered, while TS increased in both the VS group and the CM group (P<0.01), but changed insignificantly in the control group. Significant differences between the CM group and the control group were shown in terms of TO, LVMI, SBP, DBP and TS (P<0.01); and between the CM group and the VS group in terms of TO, LVMI and TS (P<0.01). Moreover, HRT parameters showed an evident correlation with LVMI (r=0.519–0.635, P<0.01). Combined therapy with XZK and Valsartan can improve hypertensive LVH and HRT parameters, and lessen the damage on the autonomous nervous system.  
Abstract:To evaluate the effect of Xuezhikang Capsule (血脂康胶囊) on the serum levels of inflammatory factors such as tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in patients with nonalcoholic fatty liver disease (NAFLD) and hyperlipidemia, and to explore whether it has anti-inflammatory effect. A total of 84 patients were randomly assigned to two groups with stratified block randomization, the treatment group (42 cases) and the control group (42 cases). They were treated with Xuezhikang Capsule and polyene phosphatidylcholine capsule for twenty-four weeks, respectively. The changes in serum TNF-α and IL-6 were measured by enzyme linked immunosorbent assay before treatment and at the 12th and 24th week. Compared with those before treatment, the serum levels of TNF-α and IL-6 significantly decreased in both groups after treatment (P<0.01). There was no significant change between the two groups for the treatments at different time points (P>0.05) and between the two groups for treatments at the same time points (P>0.05). Xuezhikang Capsule can inhibit the serum inflammatory factor in patients with NAFLD and hyperlipidemia.  
Abstract:To observe the effect of Chinese medicine therapy combined with psychological intervention (combined therapy) on the clinical symptoms and levels of blood lipids and sex hormones of patients of peri-menopausal syndrome complicated with hyperlipidemia. With the use of a randomizing digital table method, 185 patients that fit the registration standard were randomly assigned to three groups. The 59 cases in Group A were treated with two Chinese patents, Kunbao Pill (坤宝丸) and Modified Xiaoyao Pill (加味逍遥丸); the 63 in Group B received psychological intervention alone; and the 63 in Group C were treated with both (the combined therapy), with the treatment course for all six months. The items of observation included: (1) scoring by SCL-90 on eight factors and seven symptoms; (2) scoring on Chinese medicine symptoms by Kupermann scale, including anxiety and bad temper, scorching sense ation with sweating, dizziness, tinnitus, soreness and weakness of the loin and knees, palpitation, insomnia, lassitude, weakness, and hyposexuality; (3) blood contents of total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apoprotein AI (ApoAI) and B (ApoB); (4) levels of sex hormones, including estradiol (E2), progesterone (P), pituitary prolactin (PRL), follicular stimulating hormone (FSH), and), luteinzing hormone (LH) in some randomly selected patients; (5) adverse reaction; and (6) one-year follow-up study on long-term effect. A total of 21 patients (6, 8, and 7 cases in Groups A, B, and C, respectively) dropped out; the drop-out rate was insignificant among groups. (1) The markedly effective rates in Group A, B, and C were 26.42% (14/53), 18.18% (10/55), and 53.57% (30/56), respectively, and the total effective rates in them were 64.15% (34/53), 50.91% (28/55), and 87.50% (49/56), respectively, suggesting the therapeutic efficacy in Group C was significantly better than that in Groups A and B (P<0.01). (2) SCL-90 scoring showed that the total scores decreased significantly after treatment in Group C (P<0.01), but remained unchanged in Groups A and B (P>0.05). (3) Scoring on Chinese medicine symptoms showed the same results as shown by SCL-90 scoring in terms of total scores and individual symptoms, except that menstrual disorder and amenorrhea were unchanged in all three groups (P>0.05). (4) Levels of HDL-C, ApoAI, and E2 increased and those of TG, TC, LDL-C, ApoB, FSH, and LH decreased after treatment in Group C, reaching near normal levels; similar trends of blood lipids were shown in Group A, but the level of sex hormones was unchanged. In Group B all the above-mentioned indices were unchanged (P>0.05). (5) A one-year follow-up study showed the markedly effective rate and the total effective rate in Group C were higher than those in the other two groups respectively (P<0.01). (6) No adverse reaction was found. Chinese medicine therapy combined with psychological intervention could not only improve the nervous symptoms, but also regulate the blood levels of lipids and sex hormones in patients of peri-menopausal syndrome complicated with hyperlipidemia.

Abstract:To explore the effect of Tanreqing Injection (痰热清注射液, TRQI) on the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with Chinese medicine syndrome of retention of phlegm and heat in Fei (痰热阻肺证, RPHF). In a prospective randomized controlled clinical trial, 90 patients with AECOPD of RPHF syndrome were randomly assigned to 3 groups, TRQI and controls A and B, each with 30 cases. The TRQI group was administered with the intravenous injections of 20 mL TRQI once a day and conventional Western medicine treatment. Control group A was administered with the intravenous injection of 15 mg ambroxol hydrochloride twice a day and conventional Western medicine treatment, and control group B was administered with conventional Western medicine treatment only. The treatments were administered for 10 days. Chinese medical symptoms and signs were scored, and plasma concentrations of interleukin (IL)-8 and neutrophil elastase (NE) were recorded. (1) The Chinese medical symptoms (cough, sputum amount, expectoration, dyspnea and fever) and signs (tongue and pulse) improved significantly in the TRQI group (P<0.05 or P<0.01), and improvements in cough, sputum amount and expectoration were better in the TRQI group than control group B (P<0.05); there was no significant difference between the TRQI group and control group A (P>0.05). The sign of tongue was also improved significantly in the TRQI group (P<0.05). (2) The overall effects in the TRQI group and control group A were significantly better than in control group B (P<0.05), with no significant differences between the TRQI group and control group A (P>0.05). There was no significant difference in the total effective rate among the three groups (P>0.05). (3) After treatment, the plasma concentrations of IL-8 and NE decreased in the TRQI group and control group A (P<0.05), and the concentration of IL-8 in control group B decreased (P<0.05). The difference in IL-8 was greater in the TRQI group than in control group A and B before and after treatment, and the change in NE was greater in control group A than in the TRQI group and control group B, but there was no statistical significance among the three groups with regards to the change in IL-8 or NE (P>0.05). TRQI could improved the Chinese medical signs and symptoms in the patients with AECOPD, possibly because of the decreasing plasma levels of IL-8 and NE which could improve response to airway inflammation and mucus hypersecretion.

Abstract:To observe the difference in fatty degree, glucose-lipid disorder and adipose-hormones between diet induced obesity (DIO) rats and diet induced obesity resistance (DIO-R) rats, and to explore the effect and acting mechanism of Chinese drugs for strengthening Pi (脾, CD-SP) and those for both strengthening Pi and dissolving phlegm (CD-SPDP) in inhibiting obesity. Excepting eight rats allocated in the blank control group, the other 54 rats were fed with high-lipid forage for 12 weeks to establish models of obesity. Finally, 30 DIO rats and 8 DIO-R rats (shown by their body weight) were obtained. The DIO rats were divided into three groups, which were given gastric perfusion, respectively, with normal saline (Group A), CD-SP (Group B), and CD-SPDP (Group C). Fourteen weeks later, the animals’ body weight (BW), length (BL), blood levels of fasting insulin (FIn), fasting glucose (FBG), triglyceride (TG), cholesterol (TC), leptin (LP), neuropeptide Y (NPY), C-reactive protein (CRP), tumor necrosis factor-α(TNF-α), adiponectin (AN), and resistin (RS) were measured; insulin resistance index (IRI) was calculated, and the degree of obesity and lipid content in abdominal cavity of rats were estimated. Moreover, the levels of LP, CRP, TNF-α, AN and RS in homogenate of rats’ adipose tissues (ATH) were determined. After 12 weeks of high-lipid diet, the BW of DIO rats was higher than that of normal or DIO-R rats. After a 14-week continuous high-lipid diet feeding, in DIO rats, BW, lipid coefficient (LC), and IRI were significantly increased (P<0.01); serum levels of TNF-α, LP and AN were lower, NPY was higher, while the ATH levels of LP and AN were lower and TNF-α was higher in DIO rats than in DIO-R rats (P<0.05 or P<0.01); blood levels of FBG and lipids in DIO rats showed an increasing trend but was statistically insignificant (P>0.05); no significant difference was found in serum levels of CRP and RS due to the overly high data dispersion. Comparisons of the 3 DIO groups showed that BW, body weight index (BWI), LC and IRI were significantly lowered after treatment (P<0.01) in Group C, while these indexes were not significantly different between Group A and B; the serum levels of TNF-α, LP, and AN increased, NPY decreased in Group B and C, ATH levels of LP and AN increased, and TNF-α decreased in the two groups; but NPY, LP, and AN in blood and ATH were higher in Group C than those in Group B (P<0.05 or P<0.01). CD-SPDP could inhibit DIO and IR, showing that the effect is better than that of CD-SP, and its mechanism is related to promotion of LP and AN secretion and elevation of serum NPY.  
Abstract:To study the effects of the Weinaokang (维脑康, WNK), the active compounds extracted from Ginkgo, Ginseng, and saffron, on ischemia/reperfusion (I/R)-induced vascular injury to cerebral microvessels after global cerebral ischemia. Male C57BL/6J mice were randomly divided into 5 groups (10 animals/group): the sham group (0.5% CMC-Na, 20 mL/kg), the I/R model group (0.5% CMCNa, 20 mL/kg), the I/R+Crocin control group (20 mg/kg), the I/R+high dose WNK group (20 mg/kg), and the I/R+low dose WNK group (10 mg/kg). Bilateral common carotid artery occlusion (BCCAO, 20 min) in mice, followed by 24 h reperfusion, was built. The generation of nitric oxide (NO), the activity of nitric oxide synthase (NOS), the phosphorylation of extracellular signal-regulated kinase1/2 (ERK1/2), and the expression of matrix metalloproteinases-9 (MMP-9) and G protein-coupled receptor kinase 2 (GRK2) in cortical microvascular homogenates were evaluated. The ultrastructural morphology of cortical microvascular endothelial cells (CMEC) was observed. The transient global cerebral ischemia (20 min), followed by 24 h of reperfusion, significantly promoted the generation of NO and the activity of NOS. The reperfusion led to serious edema with mitochondrial injuries in the cortical CMEC, as well as enhanced membrane GRK2 expression and reduced cytosol GRK2 expression. Furthermore, enhanced phosphorylation of ERK1/2 and decreased expression of MMP-9 were detected in cortical micovessels after I/R (20 min/24 h). As well as the positive control Crocin (20 mg/kg, 21days), pre-treatment with WNK (20, 10 mg/kg, 21 days) markedly inhibited nitrative injury and modulated the ultrastructure of CMEC. Furthermore, WNK inhibited GRK2 translocation from cytosol to the membrane (at 20 mg/kg) and reduced ERK1/2 phosphorylation and MMP-9 expression in cortical microvessels. WNK and its active compounds (Crocin) are effective to suppress I/R-induced vascular injury to cerebral microvessels after global cerebral ischemia with the target on GRK2 pathways.  
Abstract:To investigate the mechanism of action of emodin for suppressing acute allograft rejection in a rat model of liver transplantation. Brown Norway (BW) recipient rats of orthotopic liver transplantation (OLT) were divided into three groups, Group A receiving isografting (with BW rats as donor), Group B receiving allografting (with Lewis rats as donor), Group C receiving allografting and emodin treatment (50 mg/kg daily). They were sacrificed on day 7 of post-transplantation, and their hepatic histology, plasma cytokine levels, and T-cell subset expression were detected. Compared with those in Group A, rats: in Group B exhibited severe allograft rejection with a rejection activity index (RAI) of 7.67±0.98, extensive hepatocellular apoptosis with an apoptosis index (AI) of 35.83±2.32, and elevated plasma levels of interleukin-2 (IL-2), interleukin-10 (IL-10), tumor necrosis factor-α (TNF-α), CD4+ and CD4 CD4+/CD8+ ratio. However, recipients in Group C showed a decrease in histological grade of rejection and hepatocellular apoptosis, as well as a decrease in plasma levels of IL-2, TNF-α, CD4+ and CD4+/CD8+ ratio, but elevated levels of IL-10 as compared with the allograft group. Post-OLT acute rejection could be attenuated by emodin, its mechanism of action may be associated with protecting hepatocytes from apoptosis, polarizing the Th 1 paradigm to Th2, and inhibiting the proliferation of CD4+ T cell in plasma.  
Abstract:To observe the effects of Tongguan Capsule (通冠胶囊, TGC) on post-myocardial infarction ventricular remodeling and heart function in rats. A rat model of acute myocardial infarction (AMI) was established by coronary ligation. Experimental rats were randomized to 4 groups including three model groups (Group A: captopril 5 mg/kg · day, n=7; Group B: TGC 10 g/kg · day, n=7; and Group C: placebo, n=8), and a sham-control group (Group D: blank control, n=6). Animals were treated for 4 weeks. The cardiac function of rats was assessed at the end of the experiment based on left ventricular ejection fraction (LVEF) and left ventricular short axis fractional shortening (LVFS) detected by colored echocardiography; meanwhile, the condition of ventricular remodeling was observed through the levels of left ventricular mass (LVM), plasma aldosterone (ALD), myocardial angiotensin II (Ang II) and myocardial collagen measurements. At the end of the experiment, LVEF and LVFS in Group A and B were improved significantly, while those in Group C were unchanged, the LVEF in Group A, B, C, and D was 0.57±0.46, 0.61±0.08, 0.36±0.55 and 0.76±0.02, respectively; and their LVFS was 0.31±0.52, 0.34±0.04, 0.23±0.57 and 0.45±0.03, respectively. The difference was statistically significant when comparing the two indexes in Group A and B with those in Group C and D (P<0.05). LVM, levels of plasma ALD and myocardial Ang II were lower in Group A and B than in Group C, but a comparison between Group A and B showed an insignificant difference in lowering LVM and ALD, while the lowering of Ang II was more significant in Group B than in Group A (754.7 ± 18.7 pg/mL vs 952.6±17.6 pg/mL, P<0.05). Morphological examination showed that in Group A and B the swollen myocardial cells had shrunk, with regularly arranged myocardial fibers and decreased collagen proliferation, but the improvements in Group B were more significant. TGC could markedly improve the post-infarction ventricular remodeling and cardiac function in rats, showing that the efficacy was better than or equal to that of captopril.  
Abstract:To investigate the effects and mechanisms of panaxoside Rg1 on the new vessel formation in acute myocardial infarction (AMI) rats. The AMI model of male Sprague-Dawley (SD) rats was established, and rats were randomly divided into the AMI model group, the treatment group of panaxoside Rg1, the placebo group and the treatment group of panaxoside Rg1 plus rapamycin. Cardiac creatases were determined with 1 mL blood drawn from vena caudalis of the rats 48 h after the model was successfully made. After 4 weeks, Evans blue was injected into the aorta roots of the rats, and then, red tetrazoline was dyed again and the myocardial infarction area was evaluated. The microvessel density (MVD) of infarction area was determined by the immunohistochemistry of CD31; enzyme-linked immunosorbent assay (ELISA) was used to detect the protein content of CD31 and hypoxia inducible factor-1α (HIF-1α) of the infarction area. The MVD in the infarction area and the contents of CD31 and HIF-1α in the Rg1 treatment group were higher than those in the AMI model group significantly (P<0.05). The cardiac creatase and infarction area were lower in the Rg1 treatment group than those in the AMI model group significantly (P<0.05). The above effects, however, disappeared when rapamycin, the antagonist of mammalian target of rapamycin (mTOR), was administered simultaneously. Panaxoside Rg1 could increase the expression of HIF-1α and CD31 of myocardium and stimulate the angiogenesis. The above mentioned role of panaxoside Rg1 might be related to the excitation of mTOR receptor.  
Abstract:To study the molecular mechanism of Zuogui Pill (左归丸, ZGP) and Yougui Pill (右归丸, YGP) on axonal regeneration in rats with experimental autoimmune encephalomyelitis (EAE). EAE rat model was established by bilateral rear pedes subcutaneous injection of antigen made by mixing myelin basic protein (MBP) and complete Freud’s adjuvant (CFA) in the volume ratio of 1:1. The pathological changes of axonal injury and regeneration in the brain and the spinal cord were observed on the 14th (the acute stage) and the 28th day (the remission stage) after modeling, with hematoxylin-eosin (HE) staining, silver stain, and immunohistochemical staining. The rats treated with prednisone acetate were taken as controls. Observation under the light microscope with HE staining showed a sleeve-like change in rats’ cerebrospinal parenchyma with inflammatory cell infiltration around the small vessels and neuronic denaturation, while silver staining showed excessive tumefaction and abscission of axon, and immunohistochemical analysis showed decreasing of nerve growth factor (NGF) expression at the acute stage of EAE, which was even more remarkable at the remission stage, showing significant difference as compared with the normal control (P<0.05). And the expressions of Nogo A, an axon growth inhibitor, and its receptor (Nogo-66 receptor, Ng R) were significantly higher than those in the normal control at the acute stage (P<0.01). However, after the intervention of ZGP and YGP, the pathological changes and axon damage in rats’ brain and spinal cord were much more alleviated, and the NGF expression was significantly higher than that in the model group at the acute stage (P<0.05). The expression of NGF was even stronger during the remission stage, and a better effect was shown by YGP. As for Nogo A and Ng R expressions, they were significantly lower than those in the model group at the acute stage (P<0.05), but a better effect was shown by ZGP. ZGP and YGP can prevent axonal injury and promote the axonal regeneration in rats of EAE, and the possible mechanism is to increase the expression of NGF and reduce the expression of Nogo A and its receptor. However, some differences are observed between the two Chinese preparations in their acting times and points, which provides a certain basis for revealing the modern connotation of the Chinese medicine theory on tonifying Shen (肾)-yin and Shen-yang.  
Abstract:To assess the effect of Shenmai Injection (参麦注射液, SMI) on left ventricular diastolic function (LVDF) in patients with chronic heart failure (CHF) by tissue Doppler imaging (TDI). Sixty-four CHF patients were randomly assigned to two groups, the observation group and the control group. Basic treatment including polarized liquid therapy was given to all the patients. In addition, SMI was given to patients of the observation group. The treatment duration was 14 days. TDI was performed in all the patients 3 days prior to the initiation of the treatment and one week after the medication to measure the average movement velocity of the mitral ring of the left ventricle at the early systolic stage and late diastolic stage (Ea and Aa); the outcomes were compared with the corresponding parameters obtained from blood flow Doppler echocardiography, namely, the velocity of the E-wave (E) and A-wave (A). After treatment, Ea and Ea/Aa increased and Aa decreased significantly in the observation group (P<0.05). In the control group, although some improvement was seen, there was no statistically significant change (P>0.05). No statistical significance was shown between groups in these parameters after treatment. TDI assessment shows that SMI could effectively improve the LVDF in CHF patients.  
Abstract:The International Standard Chinese-English Basic Nomenclature of Chinese medicine (ISN) was released in 2007, a nomenclature list consisting of 6 500 Chinese medical terms. ISN was the culmination of several years of collaborative diligent work of over 200 specialists who represent Chinese medicine in 68 countries. The overall goal for devising standard English nomenclature for Chinese medicine is to develop a practical international standard nomenclature for Chinese medical basic terms, to make it compatible with contemporary research and educational standards in the globalized health care service. In this article, provided is an overview of principles and methods for the multilingual translations, the processes behind the particular content of the Chinese-English ISN and an introduction to the ongoing new projects, i.e. the multilingual versions of ISN (International Standards of Chinese-Spanish, Chinese-French and Chinese-Portuguese Basic Nomenclature of Chinese Medicine).
