Objective To evaluate the diagnostic value of the 10 g nylon silk,vibration threshold value,sense of temperature,pain sense and ankle reflex in the diagnosis of diabetic peripheral neuropathy (DPN)and to search an exact diagnostic method of DPN not only economical but also easy to handle.Methods To carry out the measurements of the NCV,10 g nylon silk,vibration threshold value,sense of temperature,pain sense and ankle reflex on the patients who have been diagnosed with diabetes (DM)between April 2014 and June 2014 in the endocrinology department of our hospital.The sensitivity,specificity,positive forecast value,negative forecast value,Youden index and K value serve as assessments of the diagnostic efficiency of clinically diagnostic criteria. Results The sensitivity,specificity,positive forecast value,negative forecast value,Youden index and K value of the ankle reflex are 66.04%,95.56%,97.22%,54.43%,61.60%,and 0.5 1 in mediate accordance with the diagnostic criteria and it is the best one among the five methods.While the sensitivity and accordance of the pressure sense are of the least accordance with the diagnostic criteria.The correspondent value of the combination of vibration threshold sense,temperature sense and ankle reflex are respectively 86.79%,91.11%,95.83%,74.55%, 77.90% and 0.73,in positive accordance with the diagnostic criteria.Conclusion Among the five methods the consistency between the combination of vibration threshold sense,temperature sense and ankle reflect and diagnostic criteria is of positive accordance and can be applied in screening DPN clinically.

Objective To evaluate the effectiveness and safety of different Chinese patent medicine in improving blood lipid and microcirculation in coronary heart disease patients with phlegm-blood stasis syndrome based on network meta-analysis.Methods The randomized controlled trials(RCTs)of different Chinese patent medicine in the treatment of blood lipid and microcirculation in coronary heart disease patients with phlegm-blood stasis syndrome were collected by searching CNKI,Wanfang,VIP,SinoMed,PubMed,EMbase,Cochrane Library,and Web of science databases from the establishment of the database to April 3,2023.Literature quality evaluation and network meta-analysis were conducted using Review Manager 5.4 and Stata15.1 software.Results Thirty-seven RCTs were included,with a total sample size of 4 064 cases,involving 15 different Chinese patent medicines.The network meta-analysis showed that the efficacy of Chinese patent medicine combined with conventional Western medicine is often better than that of conventional Western medicine alone.There are no serious adverse reactions.The top three Chinese patent medicines with cumulative probability of total clinical efficacy were Guanmai Zaitong soft extract,Gualoupi Injection and Quyu Xiaoban Capsule.In terms of improving triglyceride(TG)and low-density lipoprotein(LDL-C),the top three Chinese patent medicines were Gualoupi Injection,Huxinkang Tablet and Guanxin Shutong Capsule.In terms of improving plasma viscosity and fibrinogen,the top three Chinese patent medicines were Ginkgo Damo Injection,Gualoupi Injection and Guanxin Shutong Capsule.In terms of improving endothelial function[nitric oxide(NO)and endothelin-1(ET-1)],the top three Chinese patent medicines were Ginkgo Damo Injection,Danlou Tablet and Tongmai Yuxin Pill.In terms of reducing inflammation hypersensitivity C-reactive protein(hs-CRP),the top three Chinese patent medicines were Ginkgo Damo Injection,Huxinkang Tablet and Guanxin Shutong Capsule.Conclusion The current evidence shows that the combination of TCM,which is used for the treatment of phlegm-blood stasis syndrome,with conventional Western medicine in the treatment of coronary heart disease has advantages in improving clinical efficacy,blood lipids and microcirculation.TCM especially for the treatment of phlegm-blood stasis syndrome shows more obvious advantage,such as Guanmai Zaitong soft extract and Gualoupi injection,which can be taken into consideration as part of the clinical guidelines.However,due to the limited number and quality of the included literatures,the research results still need to be verified by more high-quality,multi-center,double-blind randomized trials.The purpose is to provide more reliable evidence-based medical reference.

OBJECTIVETo evaluate the consistency between the clinical diagnostic criteria and the ascertained diagnostic criteria for diabetic peripheral neuropathy (DPN) in the Preventive and Treatment Guidelines of Diabetes in China (2013) and explore an economic, convenient, and accurate approach to DPN diagnosis.

METHODSThe patients with type 2 diabetes admitted in our department from April to June, 2014 were examined for nerve conduction velocity, 10 g nylon silk, vibration threshold value, sense of temperature and pain, and ankle reflex. The sensitivity, specificity, positive predictive value, negative predictive value, Youden index, and Kappa value were calculated to assess the diagnostic power of the two diagnostic criteria.

RESULTSOf the 151 patients enrolled, 106 (70.2%) had a diagnosis of DPN consistent with the ascertained diagnostic criteria, as compared to 86 (56.95%) who were diagnosed according to the clinical diagnostic criteria; the latter patients accounted for 81.13% of former cases. The sensitivity, specificity, positive predictive value, negative predictive value, Youden index, and Kappa value of the clinical diagnostic criteria were 80.19%, 97.78%, 98.84%, 67.69%, 77.97%, and 0.69, respectively, which were highly consistent with those of the ascertained diagnostic criteria; the sensitivity to compression showed a poor consistency between the two diagnostic criteria. In the 5 screening tests, the combined test of temperature sensation, vibration perception, and ankle reflex showed the highest AUC value among their different combinations.

CONCLUSIONThe clinical diagnostic criteria for DPN show good consistency with the ascertained diagnostic criteria, and for patients with clinical symptoms or with only one positive sign, combination of the two diagnostic criteria can achieve the maximum diagnostic power.
