Objective To systematically evaluate the influence of acupuncture-moxibustion on the peroneal nerve conduction velocity in type 2 diabetic peripheral neuropathy (DPN), and to provide clinical references for acupuncture-moxibustion treatment for DPN.Method By searching the CBM, CNKI, VIP, Wanfang, Pubmed, Springer and Medline databases, randomized controlled trials (RCT) of acupuncture-moxibustion for the type 2 DPN published from January 2000 to January 2014 were retrieved and the relevant data of the peroneal nerve conduction velocity were collected for methodological evaluation. RevMan 5.1 software was adopted to conduct the meta-analysis.Result Totally 10 RCTs were recruited with 685 cases involved, including 355 cases in the treatment group and 330 cases in the control group. The meta-analysis results indicated that acupuncture-moxibustion can produce a better effect in improving the motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV) of peroneal nerve in type 2 DPN than the treatments used in the control group, and the differences were statistically significant between the two groups [MD=3.55, 95%CI (0.79, 6.31); MD=4.10, 95%CI (0.22, 7.99)].Conclusion Acupuncture-moxibustion can improve the peroneal nerve conduction velocity in type 2 DPN, and thus is worth application in clinic. Due to the limitation of the included studies, such as small sample size and low quality of the articles and high probability of bias, RCTs of large sample size and high quality are required to confirm the above conclusions.

Plasma D-dimer is one of the degradation products of the cross-linked fibrin hydrolyzed by fibrinolysin and is also a unique metabolite of secondary fibrolysis.The change of its content is a reliable indicator for the identification of the hypercoagulabale state in vivo and primary and secondary fibrinolysis,as well as for the observation of the effectiveness of thrombolytic therapy.In recent years,D-dimer determination has gained new clinical application.

Objective To study the time-course relationship of eotaxin mRNA and TNF-? mRNA expression in the lung tissue of sensitized mice after antigen challenge and the effects of Cryptoporus polysaccharide (CP) on these expression. Methods Eotaxin mRNA and TNF-? mRNA expression was determined by semi-quantitative RT-PCR. The function implications of eotaxin mRNA and TNF-? mRNA expression were examed by detecting the number of total leucocyte and eosinophils in bronchoalveolar lavage fluid (BALF). Results Peak level of TNF-? mRNA expression appeared at 8 h and eotaxin mRNA expression at 24 h in the lung tissue of sensitized mice after antigen challenge. Compared with the control group, total numbers of leukocyte and eosinophil in BALF increased in sensitized mice. CP 3, 10, and 30 mg/kg inhibited eotaxin mRNA and TNF-? mRNA expression, and inflammatory cells accumulation in airway of the sensitized mice in a dose-dependent manner. Conclusion The mechanism of inhibitory effects of CP on eotaxin mRNA and TNF-? mRNA expression may be related to the anti-allergic inflammation.
