Huangqi Guizhi Wuwu Decoction for treating diabetic peripheral neuropathy：a meta-analysis of 16 randomized controlled trials

OBJECTIVE：This meta-analysis was performed to systematically assess the efficacy and safety of the Chinese herbal medicine Huangqi Guizhi Wuwu Decoction（HGWWD） for treating diabetic peripheral neuropathy.DATA SOURCES：Six electronic databases,including the Cochrane Library,MEDLINE database,Chinese Biomedical Database,Chinese National Knowledge Infrastructure Database,Chinese Science and Technique Journals Database,and the Wanfang Database,were search ed on the internet for randomized controlled trials published up until 1 December 2015.The search terms included ＂Chinese herbal medicine＂,＂diabetic peripheral neuropathy＂ and ＂randomized controlled trials＂ in Chinese and in English.DATA SELECTION：We included randomized controlled trials using HGWWD/modified HGWWD for the treatment group,without restriction for the control group.We assessed literature quality in accordance with the Cochrane Review Handbook.A random or a fixed effects model was used to analyze outcomes using Rev Man 5.2 software.OUTCOME MEASURES：The primary outcomes were changes in symptoms and nerve conduction velocities.The secondary outcomeswere fasting blood glucose and hemorheological indexes.RESULTS：Sixteen randomized controlled trials,with a total of 1,173 patients,were included.Meta-analysis revealed that the efficacy of HGWWD for diabetic peripheral neuropathy was significantly superior compared with the control treatment（i.e.,control group）（risk ratio = 0.36,95% confidence interval（CI）：0.29–0.46,Z =8.33,P 〈 0.00001） Compared with the control group,there was an increase in median motor nerve conduction velocity（mean difference（MD） = 3.46,95%CI：1.88–5.04,Z = 4.30,P 〈 0.01） and median sensory nerve conduction velocity（MD = 3.30,95%CI：2.04–4.56,Z = 5.14,P 〈 0.01）.There was also an increase in peroneal motor nerve conduction velocity（MD = 3.22,95%CI：2.45–3.98,Z = 8.21,P 〈 0.01） and peroneal sensory nerve conduction velocity（MD = 3.05,95%CI：2.01–4.09,Z = 5.75,P 〈 0.01） in the treatment groups.No significant difference in fasting blood glucose was found between the treatment groups and the control groups（MD =-0.12,95%CI：-0.42–0.19,Z = 0.76,P = 0.45）.Plasma viscosity was significantly decreased after treatment（MD =-0.11,95%CI：-0.21 to-0.02,Z = 2.30,P = 0.02）.No significant difference in fibrinogen was detectable（MD =-0.53,95%CI：-1.28–0.22,Z = 1.38,P = 0.17）.Four trials reported that treatment groups experienced no adverse reactions.Adverse events were not mentioned in the other 12 trials.No trial reported the incidence of complications,quality of life outcomes,or health economics.CONCLUSION：HGWWD treatment improves diabetic neurologic symptoms and ameliorates nerve conduction velocities.Our study suggests that HGWWD may have significant therapeutic efficacy for the treatment of diabetic peripheral neuropathy.However,the methodological quality of the randomized controlled trials was generally low.Larger and better-designed randomized controlled trials are required to more reliably assess the clinical effectiveness of HGWWD.

A Novel Constitutive Equation for Viscoelastic-Thixotropic Fluids and its Application in the Characterization of Blood Hysteresis Loop

1 INTRODUCTIONIt is well known that viscoelasticity and thixotropy of fluids are often investigated by measuringhysteresis loops under transient conditions.For some fluids(such as blood),it has been provedthat,an“8”shaped hysteresis loop may be obtained if triangular steps of shear rate wereapplied on it(Fig.l).This kind of hysteresis loop is composed of a viscoelastic loop and athixotropic loop.The viscoelastic and thixotropic properties are unified in the formation ofthe hysteresis loop.How to describe the formation of this complex hysteresis loop and how

Restrictive Effect of Puerarin on Myocardial Infarct Area in Dogs and Its Possible Mechanism

Summary: To evaluate the protective effect of puerarin on ischemic myocardium in dogs with acute myocardial infarction (AMI) and to reveal its possible mechanism, 10 dogs were randomly divided into puerarin group (group G) and control group (group C). AMI model was established in all dogs. Puerarin or saline was administered over a period of 21 days. Coronary angiography was performed before and after ligation of coronary artery. Eight hemorheological parameters were examined before and 22 days after the operation. The infarct area and vessel density of myocardium were assessed. The infarct area in group G was smaller than that in group C. Angiography 2 h and 22 d after ligation of coronary artery revealed significant augmentation of collateral vessels in group G as compared with control group. The platelet aggregation and the blood viscosity were in- creased during AMI when compared with control phase, and the increased indexes during AMI would be inhibited when puerarin were given. Capillaries and distribution vessel density in is- chemic zone on day 22 showed statistically significant augmentation in group G as compared with control group. Puerarin might improve the opening and formation of coronary collateral circula- tion, and might inhibit the increase of platelet aggregation and the blood viscosity during AMI, and thereby improve microcirculation and restrict myocardial infarct area.
