Abstract:To observe the effect of Yiqi Yangyin Decoction (益气养阴方, YQYYD) on the quality of life (QOL) of patients with unstable angina pectoris (UAP). A total of 108 patients with UAP of qi-yin deficiency syndrome confirmed by coronary angiography were enrolled and assigned to the treated group (treated with YQYYD and conventional therapy of Western medicine) and the control group (treated with conventional therapy of Western medicine), by the use of the PROC PLAN of the SAS 6.12 software, in a prospective, randomized, controlled design. The clinical total effective rate, symptom score, QOL scale [Seattle Angina Questionnaire (SAQ)] and incidence of important clinical events were defined as the observation indices to evaluate the interventional effect of YQYYD on the QOL of patients with UAP of the qi-yin deficiency syndrome. During the study, three cases dropped out in the treated group, one case dropped out in the control group, and 104 cases, including 51 cases in the treatment group and 53 cases in the control group, finished the trial. After four weeks of treatment, the total clinical effective rates in the treated group and the control group were 80.4% and 75.5% respectively, and there was no obvious difference between them (P>0.05). However, the symptom score of the treated group (9.31±2.02) was significantly lesser than that of the control group (11.62±3.04, P<0.05), and the total score of the QOL scale of the treated group (68.76±5.74) was significantly higher than that of the control group (61.06±3.31, P<0.01). Among those in the treated group physical limitation, angina stability, angina frequency, and treatment satisfaction were significantly ameliorated when compared with the control group after treatment (P<0.05, P<0.01). The incidence of important clinical events in the treated group (3.9%) was lower than that in the control group (5.7%) during the 8-month follow-up period, but the difference was insignificant (P>0.05). YQYYD could improve the clinical symptoms of patients with UAP of qi-yin deficiency syndrome and greatly improve their QOL.  
Abstract:To observe the effect of Chinese medicine therapy for strengthening-Pi (脾) and nourishing-Shen (肾, SPNS) in preventing lamivudine induced YMDD mutation and its immunological mechanism. One hundred and sixty chronic hepatitis B (CHB) patients with positive HBeAg were equally assigned to two groups at random: the observation group and the control group. Patients in the observation group were treated with lamivudine combined with SPNS, and those in the control group were treated with lamivudine only, with the treatment lasting for 52 weeks in total. Changes in indexes, including liver function, HbeAg, HBV-DNA, YMDD variation, CD4, CD4/CD8 ratio, interferon-γ (IFN-γ), interleukin-4 (IL-4), blood routine, renal function, as well as any adverse reactions that occurred in patients, were observed at different time points. The ALT, AST recovery rate and HBV-DNA negatively inversing rate at the 24th week, the 36th week and the 52nd week were all higher (P<0.05); meanwhile, the YMDD mutation rate at the 36th week and the 52nd week was lower (P<0.05) in the observation group than in the control group. The posttreatment levels of CD4, CD4/CD8 ratio, IFN-γ, and IL-4 as well as the pre-post treatment difference of these indexes in the observation group were significantly different from those in the control group (P<0.05). Chinese medicine SPNS therapy can significantly reduce the YMDD variation of HBV, and the mechanism may be related to its regulation of the CD4 level, CD4/CD8 ratio and Th1/Th2 balance.

Abstract:To observe the therapeutic effect and safety of Qianggan Capsule (强肝胶囊, QGC) in treating non-alcoholic fatty liver disease (NAFLD), using polyene phosphatidylcholine capsule (PPC) as a reference. Eighty-eight patients with NAFLD were randomly assigned to two groups, 45 in the treatment group treated with QGC and 43 in the control group treated with PPC. The course of treatment lasted for 6 months. Changes in liver function, blood lipids, and iconographic indexes before and after treatment were observed, and clinical efficacy was evaluated. In the treatment group, alanine aminotransferase (ALT) was lowered significantly from 56.02±32.59 IU/L before treatment to 38.27±22.68 IU/L after treatment, and CT liver/spleen ratio significantly increased from 0.69±0.18 to 0.91±0.25, showing statistical significance (P<0.05); in contrast, the corresponding changes of the two indexes in the control group were 56.56±26.33 IU/L to 49.67±26.22 IU/L, and 0.66±0.20 to 0.75±0.24, respectively, the pre-post treatment difference showing insignificant difference (P>0.05). No severe adverse reactions occurred during the whole treatment course. QGC is an effective and safe remedy for the treatment of NAFLD.  
Abstract:To explore the relationship between yin-deficiency constitution (YDC) and biochemical indexes by way of observing the endocrinal and immune functions in subjects with YDC. On the basis of epidemiological investigation, 60 subjects with YDC and 50 with gentle constitution (GC) were selected according to the pertinent criteria. From each subject, 8 mL of fasting venous blood was drawn at 8:00–9:00 in the morning, with the serum separated by centrifugation 3 000 r/min for 5 min and preserved at −70°C in a freezer. Serum levels of corticosterone, cortisol, adrenocorticotrophic hormone (ACTH), cyclic adenosine monophosphate (cAMP), cyclic guanosine monophosphate (cGMP), free triiodothyronine (FT3), free thyroxine (FT4), throtropic stimulation hormone, interleukin 1β (IL-1β) and interleukin 2 (IL-2) were detected by double-antibody sandwich ELISA; cAMP/cGMP ratio was calculated, and the difference between the two constitutions in terms of these indexes was analyzed. Serum FT3 was 4.16±1.38 pmol/L in subjects with YDC, which was higher than that in subjects with GC (3.71±0.55 pmol/L), but levels of cortisol (124.58±45.36 ng/mL), ACTH (58.92±14.55 pg/mL), cGMP (66.00±18.02 pmol/mL) and FT4 (12.33±3.12 pmol/L) in YDC were lower than those in GC (13.43±2.31 pmol/L), showing significant difference (P<0.05). YDC is related to some extent with the disturbances in the hypothalamus-pituitary-adrenal axis, hypothalamus-pituitary-thyroid axis, cyclic nucleoside system and immune function.

Abstract:Periplocin is an active digitalis-like component from Cortex Periplocae, which has been widely used in the treatment of heart diseases in China for many years. According to the recommendations on the cardiovascular effect of periplocin from in vivo experiments, subsequent in vitro experiments are greatly needed for the global assessment of periplocin. The objective of this study is to investigate the cell proliferation effect and the mechanism of periplocin on endothelial cells. The proliferative activity of periplocin (0.4, 2, 10, 50, 250 μmol/L; 6, 12, 24, 48, 72 h) was investigated by a comparison with the well-reported cardiac glycoside, ouabain, on mouse cardiac microvascular endothelial cells (CMEC). 3-(4,5-dimethylthiazolyl)-2,5-diphenyltetrazolium bromide (MTT), lactate dehydrogenase (LDH) and 5-bromo-2-deoxyuridine (BrdU) assays were used to evaluate cell proliferation and viability. Subsequently, cDNA microarray experiments were performed on periplocin- (50 μmol/L) and ouabain- (50 μmol/L) treated cells, and data was analyzed by ArrayTrack software. Periplocin could increase cell viability to a level lower than ouabain in the MTT analysis, but decrease LDH release simultaneously. The BrdU incorporation assay showed an increase in cell proliferation with 2–50 μmol/L periplocin. Genes related to protein serine/threonine kinase were the most significantly enriched in the 160 genes identified in periplocin versus the control. In the 165 genes regulated by periplocin versus ouabain, GTP-binding was the most altered term. The results demonstrated the proliferation action of periplocin on CMEC. Meanwhile, its lower cytotoxicity compared to ouabain provides a new insight into the treatment of heart failure.  
Abstract:Changes of the internal and external cellular environments can induce calcium homeostasis disorder and unfolded protein aggregation in the endoplasmic reticulum (ER). This ER function disorder is called endoplasmic reticulum stress (ERS). Severe long-term ERS can trigger the ER apoptosis signaling pathway, resulting in cell apoptosis and organism injury. Recent researches revealed that ERS-induced cell death was involved in the neurocyte retrogradation in the progress of neuron degenerative diseases, such as Alzheimer’s disease (AD), Parkinson’s disease and so on. Therefore, the protection effect of the traditional Chinese drug—Tiantai No. 1 (天泰1号) on the ERS injury of AD was investigated at the molecular gene level in this study with a view to explore the gene pharmacodynamic actions and mechanisms of this drug. Primarily cultured marrow mesenchymal stem cells (MSCs) of rats were treated by tunicamycin (TM) in order to induce ERS. RT-PCR, fluorescence immunocytochemistry and Western blot techniques were used to determine the mRNA and protein expression levels of the protective stress protein-ER molecular chaperones GRP78 and GRP94 (which would assist cells to resist cellular stress injury), and to determine the mRNA and protein expression levels of apoptosis promoting molecule Caspase-12 on the membrane of the ER, respectively. Protein expression levels of GRP78 and GRP94 were significantly increased in the TM-induced MSCs, and the mRNA level of Caspase-12 was also remarkably increased in the TM-induced MSCs (P<0.05). All these proved that the ERS model was successfully established by TM in MSC. Meanwhile, the mRNA and protein levels of GRP78 and GRP94 were all significantly increased compared with the model group (P<0.05 or P<0.01) after MSCs were treated with Tiantai No.1 while the mRNA and protein expression levels of Caspase-12 were significantly decreased compared with the model group (P<0.05 or P<0.01). This effect showed a dose dependent manner. Tiantai No.1 might attenuate the cell apoptosis induced by ERS injury, and thus protect the neurons against AD.  
Abstract:To observe the effect of Xuefu Zhuyu Decoction (血府逐瘀汤)-containing serum (XFZYD-CS) on endothelial progenitor cell (EPC) tube formation in vitro. Mononuclear cells from rat bone marrow were prepared in a Ficoll density gradient centrifuge. EPCs were separated by the differential attachment method, and observed with inverted microscope for the effect of XFZYD-CS on EPC tube formation. After one day, EPCs exposed to the serum containing 5%, 10% and 15% XFZYD-CS formed typical tubes or vessel networks. The tube formation time was two days ahead of the control group and the size of most tubes in the serum groups was smaller than in the control group. XFZYD-CS could induce EPC angiogenesis and hasten tube formation, especially in capillary vessels. The study provides experimental evidence for the plausibility of Xuefu Zhuyu Decoction in the treatment of ischemic diseases.  
Abstract:To observe the changes of vascular endothelial functions and general neuro-endocrine-immunity (NEI) network under the state of qi-deficiency syndrome induced by excessive idleness and to approach their internal relevance and illuminate initially the pathophysiological mechanism of vascular lesion induced by excessive idleness. A total of 100 male Wistar rats were randomly divided into the control group and the qi-deficiency syndrome model group, 50 rats in each group. The qi-deficiency syndrome model was established by feeding the animals with hyper-alimentation diet in combination with restricting movement for 10 weeks. Changes of common chemical signal molecules related to NEI and vascular endothelial functions were measured by the end of the experiment. Furthermore, their internal relevance was analyzed by the method of canonical correlation analysis. The vascular endothelial structure and function were obviously injured in the model group. Compared with the control group, the chemical signal molecules, such as 5-hydroxytryptamine (5-HT), corticosterone (CORT), triiodothyronine (T3), tetraiodothyronine (T4), angiotensin II (Ang II), interleukin-1 (IL-1), and tumor necrosis factor-α (TNF-α) in peripheral blood of the model group (n=43) were changed significantly (P<0.05 or P<0.01). Canonical correlation analysis showed that vascular endothelial dysfunction was correlated to the changes of these signal molecules in the NEI network. Comfort-based lifestyle induced not only vascular endothelial dysfunction but also an imbalance of the NEI network. Vascular endothelial dysfunction and the imbalanced NEI network interacted with each other, and an imbalance of the NEI network may be the pathophysiologic basis for the genesis and development of vascular endothelial dysfunction, even diseases of the blood vessel.

Abstract:To study the effect of Xinjining extract (心悸宁, XJN) on inward rectifier potassium current (IK1) in ventricular myocyte (VMC) of guinea pigs and its anti-arrhythmic mechanism on ion channel level. Single VMC was enzymatically isolated by zymolisis, and whole-cell patch clamp recording technique was used to record the Ik1 in VMC irrigated with XJN of different concentrations (1.25, 2.50, 5.00 g/L; six samples for each). The stable current and conductance of the inward component of IK1 as well as the outward component of peak IK1 and conductance of it accordingly was recorded when the test voltage was set on −110 mV. The suppressive rate of XJN on the inward component of IK1 was 9.54%±5.81%, 34.82%±15.03%, and 59.52%± 25.58% with a concentration of 1.25, 2.50, and 5.00 g/L, respectively, and that for the outward component of peak IK1 was 23.94%±7.45%, 52.98%±19.62%, and 71.42%±23.01%, respectively (all P<0.05). Moreover, different concentrations of XJN also showed effects for reducing IK1 conductance. XJN has inhibitory effect on IK1 in guinea pig’s VMC, and that of the same concentration shows stronger inhibition on outward component than on inward component, which may be one of the mechanisms of its anti-arrhythmic effect.

Abstract:To study the effect of Gan (肝)-Pi (脾) regulatory needling (GPRN) in treating chloasma and its influences on female sex hormones, superoxide dismutase (SOD), lipid peroxide (LPO) and melanocyte-stimulating hormone (MSH). Ninety chloasma patients were equally randomized to three groups, the treatment group treated with GPRN, the control group treated with conventional Western medicine and the blank group untreated. Changes in the scores of skin lesion (area and color) and symptom, as well as blood levels of female sex hormones, MSH, SOD and LPO were observed and compared after 3 months of treatment. In the treatment group, the scores of skin lesion area and color were reduced from 2.76±0.96 and 2.48±0.78 before treatment to 1.42±0.42 and 1.03±0.41 after treatment, respectively, while in the control group they were from 2.78±1.06 and 2.53±0.88 to 1.58±1.23 and 1.28±0.96, respectively, all showing significant changes (P<0.05); the scores were insignificantly changed in the blank group (P>0.05). At the same time, the score of symptoms in the treatment group significantly improved after treatment (P<0.05), significantly different from that of the other two groups. Comparison of female sex hormones among groups showed no significant differences either before or after treatment. The level of LPO decreased and SOD increased in both the treatment group and the control group significantly (all P<0.05), but significant lowering of MSH was only seen in the treatment group (P<0.05). GPRN can effectively lessen the size and lighten the color of chloasma, improve the accompanying symptoms in patients and decrease LPO and MSH levels and increase the SOD level, but will not affect the level of the female sex hormones.  
Abstract:To investigate the effects of acupuncture on the morphine-related side effects (nausea, vomiting, itchiness and gastrointestinal disorders) in patients undergoing anesthesia and analgesia and try to find the clinical mechanism of acupuncture. Patients scheduled to have transurethral prostatic resection: enrolled in the study (69 patients), characterized as Grade II or III by the American Society of Anesthesiologists physical status classification, were randomly assigned to three groups, 23 patients in each group: the placebo group (control group), non-anesthesia area (NAA) group, and the anesthesia area (AA) group. After spinal anesthesia, all patients received Patients Controlled Epidural Analgesia. The vital signs, bowel sounds, visual analogue scales, itchiness, nausea and vomiting, and time for first exhaust post operation were observed. Altogether, nine cases were eliminated, three in each group. Finally, sixty cases completed this study,: twenty in each group. There was a significant decrease of bowel sounds after morphine spinal anesthesia in the three groups. Compared with the control or AA group, the bowel sound recovered after acupuncture, the incidences of nausea and vomiting, itchiness, and time for first exhaust after operation decreased in the NAA group (P<0.05). There was a significant decrease of the incidence for itchiness in the NAA group compared with

Abstract:The existing efficacy evaluation for coronary heart disease (CHD) angina pectoris does not demonstrate the characteristics and advantages of Chinese medicine (CM), so a new system of efficacy evaluation which can scientifically and systematically reflect the specific features of CM needs to be urgently set up. Based on wide references of efficacy evaluations of CHD angina pectoris from our country and abroad, and considering the general acceptance by academic circles and demonstration of the characteristics of CM, this paper tries to set up a new index system of efficacy evaluation, combining both disease and syndrome differentiation for CHD angina pectoris. This paper also offers some explorations based on the results of clinical trials. The system is composed of six aspects, including efficacy evaluation of “disease”, syndrome factors and main endpoints (the incidence of important clinical events), as well as patient reported outcomes, safety evaluation and medical economics.

Abstract:The study proposes to explore two alternative medicine therapies-qigong and yoga for balancing the essential duo of holistic mind-body and consequently offer a solution for stress, uncertainty, anxiety and depression. Qualitative research methods have been used to create a conceptual synthesis of yoga and qigong. It is suggested that an increased sense of control is the interface between these two modalities. This conceptual congruence of qigong and yoga is thought to be a selective, curative method, a prescription for ideal living and a ground of human essence existence. Furthermore, this essence is thought to enhance the mind’s self-regulatory processes and prevent mental health disorders. The two alternative therapies can prevent mental health disorders such as anxiety, depression and, minimize mental health disruptions such as stress and poor quality of life. It is suggested that patients and/or clients can benefifit from this fusion.  
Abstract:Cytomegaloviral hepatitis is an infantile liver disease commonly encountered in China, which could be differentiated into 4 patterns with different clinical conditions. Along with the progress of laboratory diagnostic techniques, multiple diagnostic approaches are available for this disease, but accurate diagnosis can only be made when individual patients’ realities are taken into consideration. Clinical treatments are various, and the Western medicine used is mainly anti-viral agents such as Ganciclovir, and so far no unified therapeutic program has been formed. More and more ways of regarding Chinese medicine treatment of cytomegaloviral hepatitis have been published increasingly in recent years, though further research to seek preferable treatment programs is still expected.
