- Abstract：Diabetes mellitus (DM) is a metabolic disorder caused by insufficient or inefficient insulin secretary response and it is characterized by increased blood glucose levels (hyperglycemia). DM is a heterogonous group of syndromes. Glucose is the main energy source for the body, and in the case of DM, management of glucose becomes irregular. There are three key defects in the onset of hyperglycemia in DM, namely increased hepatic glucose production, diminished insulin secretion, and impaired insulin action. Conventional drugs treat diabetes by improving insulin sensitivity, increasing insulin production and/or decreasing the amount of glucose in blood. This article provides a comprehensive review of the mode of action of most popular hypoglycemic herbs, such as ginseng, bitter melon, fenugreek, banaba, Gymnema sylvestre and Coptis chinensis. The herbs act by increasing insulin secretion, enhancing glucose uptake by adipose and skeletal muscle tissues, inhibiting intestinal glucose absorption and inhibiting hepatic glucose production. Although evidence from animals and humans consistently supports the therapeutic effect of these phytomedicines, multicenter large-scale clinical trials have not been conducted to evaluate the safety and efficacy of these herbal medicines and their interaction with conventional drugs when administered simultaneously.Keywords：hyperglycemia;medicinal plants;ginseng;bitter melon;fenugreek;banaba

Published：2021-08-27 - Abstract：Moxibustion is currently used for treating diabetes mellitus (DM) as a non-drug intervention in East Asian countries. This systematic review aims to evaluate the effectiveness of moxibustion for managing the symptoms of type 2 DM patients. We searched MEDLINE, AMED, EMBASE, CINAHL, The Cochrane Library, six Korean databases, and four Chinese databases. Risk of bias was used for evaluating the quality of the included studies. A total of 5 studies met the inclusion criteria for this review. All of the included studies had high risks of bias. One randomized clinical trial (RCT) compared the effectiveness of one-time moxibustion use with oral administration of glibenclimide and showed the significant effects of moxibustion on glycemic control. Another RCT tested the effectiveness of moxibustion plus conventional treatment, and the moxibustion group reported significant improvement in fasting and postprandial blood glucose levels compared with the conventional treatment group. Two RCTs compared the effectiveness of moxibustion versus acupuncture or moxibustion plus acupuncture, and the combined treatment showed the most favorable effects on the control of blood glucose, urine glucose, and glycocylated hemoglobin A1c (HbA1c). One uncontrolled observational study showed favorable effects of moxibustion on the response rate. It is difficult to conclude that moxibustion is an effective intervention for the control of type 2 DM due to the scarcity of trials and the low methodological quality of included studies. Further rigorous RCTs may be necessary to evaluate the effectiveness of moxibustion for type 2 DM.Keywords：moxibustion;diabetes mellitus;type 2 diabetes mellitus;blood glucose;systematic review

Published：2021-08-27 - Abstract：To evaluate the effectiveness of acupuncture as a treatment for neurovascular headache and to analyze the current situation related to acupuncture treatment. PubMed database (1966–2010), EMBASE database (1986–2010), Cochrane Library (Issue 1, 2010), Chinese Biomedical Literature Database (1979–2010), China HowNet Knowledge Database (1979–2010), VIP Journals Database (1989–2010), and Wanfang database (1998–2010) were retrieved. Randomized or quasi-randomized controlled studies were included. The priority was given to high-quality randomized, controlled trials. Statistical outcome indicators were measured using RevMan 5.0.20 software. A total of 16 articles and 1 535 cases were included. Meta-analysis showed a significant difference between the acupuncture therapy and Western medicine therapy [combined RR (random efficacy model)=1.46, 95% CI (1.21, 1.75), Z=3.96, P<0.0001], indicating an obvious superior effect of the acupuncture therapy; significant difference also existed between the comprehensive acupuncture therapy and acupuncture therapy alone [combined RR (fixed efficacy model)=3.35, 95% CI (1.92, 5.82), Z=4.28, P<0.0001], indicating that acupuncture combined with other therapies, such as points injection, scalp acupuncture, auricular acupuncture, etc., were superior to the conventional body acupuncture therapy alone. The inclusion of limited clinical studies had verified the efficacy of acupuncture in the treatment of neurovascular headache. Although acupuncture or its combined therapies provides certain advantages, most clinical studies are of small sample sizes. Large sample size, randomized, controlled trials are needed in the future for more definitive results.Keywords：neurovascular headache;acupuncture;randomize controlled trials;systematic review

Published：2021-08-27 - Abstract：To study the distribution of gelsolin in human platelet and plasma, and the association with blood-stasis syndrome (BSS) of coronary heart disease (CHD). Sixty patients with CHD (30 in BSS group and 30 in non-BSS group) and 30 healthy subjects (control group) were included in this study. The classification of the syndrome was based on clinical symptoms and signs. Gelsolin concentration in platelet rich plasma (PRP), platelet poor plasma (PPP), filamentous actin (F-actin) and group-specific component globulin (Gc-globulin) of PPP were determined by enzyme-linked immunosorbent assay (ELISA). The fluorescence intensity of CD62p and cytoplasmic calcium ([Ca2+]i) in human platelets of patients and healthy persons was measured with flow cytometry. Compared with the control group, gelsolin in PRP of the BSS group increased significantly (P<0.01), while that in PPP of the BSS and non-BSS groups decreased markedly (P<0.05), the CD62p, [Ca2+]i of platelet, F-actin, and Gc-globulin of the BSS and non-BSS groups increased significantly (P<0.01). Compared with the non-BSS group, the gelsolin concentration in PRP of BSS group increased significantly (P<0.01), the [Ca2+]i of platelet of the BSS group increased markedly (P<0.01), while the F-actin and Gc-globulin of the BSS group had no statistical defference (P>0.05). Gelsolin concentration in PRP was increased and accompanied by the elevated [Ca2+]i of platelet in CHD with BSS, while gelsolin in PPP were lowered markedly. We speculate that plasma gelsolin may clear F-actin from circulation, thus resulting in depletion of plasma gelsolin significantly. This, in addition to the increased calcium influx of platelets, may lead to the gelsolin abnormal expression on platelets during the process of BSS in CHD. Therefore, platelet gelsolin may serve as a new potential biomarker and a therapeutic target of BSS in CHD.Keywords：gelsolin;filamentous actin;coronary heart disease;Blood Stasis Syndrome;platelet activation

Published：2021-08-27 - Abstract：To evaluate the efficacy and safety of Yiqi Zhuyu Decoction (益气逐瘀汤, YZD) combined with oxaliplatin plus 5-flurouracil/leucovorin (FOLFOX-4) in the patients with metastatic colorectal cancer (MCRC). A total of 120 patients with MCRC were randomly divided into the experimental group (FOLFOX-4 plus YZD, 60 cases) and the control group (FOLFOX-4 plus placebo, 60 cases), according to the sequence of hospitalization from January 2005 to December 2007. The treatment was supposed to be continued until disease progression (PD) or for 48 weeks (i.e., up to 24 cycles of FOLFOX-4). Response rate (RR), progression-free survival (PFS), overall survival (OS) and adverse events (AEs) were observed. RR was 41.5% in the experimental group and 34.0% in the control group [odds ratio (OR): 1.18, 95% CI: 0.77 to 1.82, P=0.432]. Median PFS were 9.0 months and 8.0 months, respectively [hazard ratio (HR): 0.78, 95% CI: 0.53 to 1.15, P=0.215]. Median OS were 21.0 months and 18.0 months (HR: 0.65, 95% CI: 0.43 to 0.99, P=0.043) and grade 3/4 AEs were 56.6% and 76.7% (OR: 0.61, 95% CI: 0.18 to 0.87, P=0.020), respectively. YZD combined with FOLFOX-4 chemotherapy significantly improved OS in this first-line trial in the patients with MCRC and significantly decreased grade 3/4 AEs. However, RR was not improved, and PFS did not reach statistical significance by the addition of YZD. The treatment of YZD combined with FOLFOX-4 may be necessary in order to optimize efficacy and safety.Keywords：colorectal cancer;chemotherapy;FOLFOX-4;Chinese Medicine;Yiqi Zhuyu Decoction

Published：2021-08-27 - Abstract：To investigate the relationship between respiratory diseases onset and the meteorological factors in the same period and in a specific environment. By using the data of daily incidence of respiratory diseases obtained from Dongzhimen Hospital Affiliated to Beijing University of Chinese Medicine from January 1, 1998 to December 31, 2007, and the data of 16 items of meteorological factors (such as the average, maximum, and minimum temperatures, etc., including meteorological factors derived) obtained from the Beijing Municipal Meteorological Observatory, mathematical statistical methods were applied to achieve the non-linear correlation analysis, or the correlation test, between the incidence of respiratory diseases and the time-related meteorological factors. The simple correlation coefficients of the relationship between the incidence of respiratory diseases and 9 meteorological elements, including the average values of temperature, maximum temperature, minimum temperature, degree of comfort, precipitation, vapor pressure, low cloud cover, change of vapor pressure, and change of wind speed, were all greater than 0.8286, in which one of the relationship between the incidence of respiratory diseases and the maximum temperature is as high as 0.9670. Statistical tests showed R>Rα=0.05 and F>Fα=0.05. The incidence of respiratory diseases was closely correlated to meteorological factors, such as air temperature, vapor pressure, precipitation, wind speed, etc. To a certain extent, this conclusion confirmed the scientificity and objectivity of the theory of five evolutive phases and six climatic factors (Wu Yun Liu Qi, 五运六气) in Huang Di Nei Jing (黄帝内经, The Yellow Emperor’s Canon of Internal Medicine).Keywords：respiratory diseases;meteorological factors;degree of correlation;Chinese Medicine;five evolutive phases and six climatic factors

Published：2021-08-27 - Abstract：To investigate the proliferation-inhibiting and apoptosis-inducing effects of ursolic acid (UA) and oleanolic acid (OA) on multi-drug resistance (MDR) cancer cells in vitro. UA and OA in different concentrations (0–100 μmol/L) were added separately to cultures of different cancer cell lines, including the human colon cancer cell lines SW480 and SW620, human acute myelocytic leukemia cancer cell lines HL60 and HL60/ADR, human chronic myelogenous leukemia cell lines K562 and K562/ADR, and the human breast cancer cell lines MCF-7 and MCF-7/ADR. Effects of UA and OA on cell proliferation were detected by 3-(4,5-dimethyl-2-thiazole)-2-5-biphenly-tetrazole bromide (MTT) method and effects on cell apoptosis were tested by flow cytometry (FCM) and Western blot at 24, 48, and 72 h after treatment. Both UA and OA showed significant inhibition on parent and MDR cell lines in a time- and concentration-dependent manner; the drug-resistant multiple of them on K562 and K562/ADR as well as on HL60 and HL60/ADR was 1; the effects of UA were better than those of OA in inhibiting cell growth of solid colonic cancer and breast cancer. After SW480 cells were treated by UA at the concentrations of 0–40 μmol/L for 48 h, FCM showed that annexin V (AV) positive cells and hypodiploid peak ratio increased along with the increase in the drug’s concentrations; and Western blot found that expressions of Bcl-2, Bcl-xL and survivin decreased in a concentration-dependent manner. Both UA and OA have antitumor effects on cancer cells with MDR, and the optimal effect is shown by UA on colonic cancer cells. Also, UA shows cell apoptosis-inducing effect on SW480, possibly by way of down-regulating the expressions of apoptosis antagonistic proteins, Bcl-2, Bcl-xL, and survivin.Keywords：Ursolic Acid;Oleanolic Acid;multi-drug resistance cancer cell;proliferation inhibition;apoptosis

Published：2021-08-27 - Abstract：To explore the effects and underlying mechanisms of Panax notoginoside (PNS) on the nephropathy in rats with type 1 diabetes. A murine model of diabetic nephropathy was set up by an intravenous injection of streptozotocin (STZ). Wistar rats were randomly divided into 5 groups: the control group, the diabetic group (DM), the group treated with low-dosage PNS (PNS-L), the group treated with high-dosage PNS (PNS-H) and the group treated with catopril. Rats in the PNS-L and PNS-H groups were given different dosages of PNS while rats in the catopril group were given catopril through gastrogavage every day for the next four consecutive weeks. Serum creatinine (Cr) levels, endogenous creatinine clearance rate (CCr), and 24-h urinary microalbumin (UAlb) were examined and calculated. Meanwhile, immunohistochemistry was applied to determine the expression of vascular endothelial growth factor (VEGF) and bone morphogenetic protein-7 (BMP-7) in the kidney tissue. The levels of Cr, Ccr, and UAlb were all elevated significantly in the DM group (P<0.01). The expression of VEGF protein was increased but BMP-7 protein was decreased in the kidney tissue (P<0.01). However, the above items decreased in the PNS-L, PNS-H and catopril groups compared with the DM group (P<0.05, P<0.01). In the PNS-L, PNS-H and catopril groups, the expression of VEGF protein was decreased but BMP-7 protein was increased in the kidney tissue (P<0.05, P<0.01). PNS shows protective effects on the kidney in type 1 diabetic rats at the early stage. The protective mechanism might be closely related to its role of inhibiting the expression of VEGF protein and enhancing the expression of BMP-7 protein in the kidney.Keywords：type 1 diabetes;diabetic nephropathy;Panax notoginoside

Published：2021-08-27 - Abstract：To investigate the effect of total alkaloids of Sophora alopecuroides (TASA) on dextran sulfate sodium (DSS)-induced colitis in mice. Chronic experimental colitis was induced by administration of 4 cycles of 4% DSS. Fifty mice were randomly distributed into 4 groups (normal, DSS, DSS/high-dose TASA, and DSS/low-dose TASA groups) by a random number table with body weight stratification. Mice in the normal group (n=11) and DSS-induced colitis control group (n=15) received control treatment of 20 mL/kg distilled water; DSS plus TASA high- and low-dose groups (n=12 each) were treated with TASA solution (20 mL/kg) at the doses of 60 mg/kg and 30 mg/kg, respectively. The severity of colitis was assessed on the basis of clinical signs, colon length, and histology scores. Moreover, secretory immunoglobulin A (sIgA) and haptoglobin (HP) were analyzed by enzyme linked immunosorbent assay; intercellular adhesion molecule 1 (ICAM-1) and macrophage-migration inhibitory factor (MIF) gene expressions were analyzed by quantitative reverse transcriptase realtime polymerase chain reaction (qRT-PCR) using SYBA green I; and nuclear factor κ B (NF-κ B) expression and activation and p65 interaction with the promoter of ICAM-1 gene were assessed by Western blotting and chromatin immunoprecipitation assay. TASA administration significantly attenuated the damage and substantially reduced HP elevation and maintained the level of cecum sIgA. TASA inhibited the ICAM-1 gene expression and had no effect on MIF gene expression. Also, TASA was able to reduce phospho-I κ B α (p-I κ B α) protein expression; however, it had no effect on the activation of I κ B kinase α (IKK α) and inhibitor of NF-κ B α (I κ B α). Moreover, TASA inhibited the p65 recruitment to the ICAM-1 gene promoter. TASA had a protective effect on DSS-induced colitis. Such effect may be associated with its inhibition of NF-κ B activation and blockade of NF-κ B-regulated transcription activation of proinflammatory mediator gene.Keywords：total alkaloids of Sophora alopecuroides;dextran sulfate sodium;colitis;nuclear factor κ B signal;transduction pathway

Published：2021-08-27 - Abstract：To investigate the effects of Salvia Miltiorrhiza Liguspyragine Hydrochloride and Glucose Injection (参芎葡萄糖注射液, SLGI) on the expression of platelet membrane receptors proteinase-activated receptor-1 (PAR1) and proteinase-activated receptor-4 (PAR4) in end-stage renal disease (ESRD) patients on chronic haemodialysis (HD). Eighty-six ESRD patients on HD (treated group) were treated with SLGI, 7 days as one therapeutic course, for two successive courses. The previous therapies were unchanged. Flow cytometry was used to assess the expression of platelet PAR1 and PAR4 in the patients, and turbidity method was used to determine the platelet maximum aggregation rate (MAR). Meanwhile, renal function was measured. The final data were compared with those before treatment and with those in the normal control group (54 healthy subjects). Compared with the normal control group, the expressions of PAR1 and PAR4 and platelet MAR in ESRD patients on HD was significantly higher before treatment (P=0.001, P=0.006, and P=0.008); after treatment with SLGI, the above indices in patients were remarkably decreased (P=0.036 and P=0.046), except PAR4 (P=0.067), but still higher than those in the normal control group, however, it was not statistically significant. (1) The overexpression of PAR1 and PAR4 might lead to increased platelet aggregation and this could be one of the reasons for the thrombotic events in ESRD patients on HD. (2) SLGI was able to down-regulate the expression of PAR1 in ESRD patients on HD, improve platelet function, and regulate platelet activation.Keywords：end-stage renal disease;chronic haemodialysis;platelet thrombin receptors;Salvia Miltiorrhiza Liguspyragine Hydrochloride and Glucose Injection
