Objective To explore characteristics of the elements of syndrome, the disease position and the relationship between chemical indicators and TCM syndromes of type 2 diabetic encephalopathy. Methods 2 501 cases of type 2 diabetes clinical data were collected from Guang'anmen Hospital of China Academy of Chinese Medical Sciences, Beijing University of Chinese Medicine, Dongzhimen Hospital, Dongfang Hospital, etc. in nearly 3 years, among which, 342 cases were type 2 diabetic encephalopathy. The original clinical data were double entried in epidata by two people, establishment forms in excel, factor analysis and Bayesian networks were used as data mining research methods. Results 20 elements which characteristic root more than 1 were derived by factor analysis, 68.4% were covered. Of all 20 elements, five factors belong to Yin, five factors belong to blood stasis; lassitude, shortness of breath, stool frequency were appeared when fasting glucose abnormalities; lassitude, hemiplegia were appeared when 2-hour postprandial blood glucose abnormalities;lassitude, feverish palms and soles, stool frequency, more nocturnal enuresis when glycated hemoglobin abnormalities by Bayesian networks. Conclusion The Elements of the syndrome of type 2 diabetes encephalopathy were deficiency of Yin and blood stasis; and the main positions for diabetic patients were liver, spleen and kidney. Patients with impaired fasting glucose were Qi deficiency; Patients with impaired 2-hour postprandial glucose were Qi deficiency or pathogenic wind attacking collaterals; Patients with abnormal hemoglobin were Qi deficiency and Yin deficiency.

Objective:To systematically evaluate effects of auricular acupoint pressing on improving perimenopausal insomnia.Methods:The randomized controlled trials of auricular plaster therapy to improve perimenopausal insomnia was searched by computer in domestic and foreign databases, and the search time was from the establishment of each database to October 25, 2018. Two researchers independently screened the literature, extracted data and evaluated the risk of bias in the included literature and RevMan 5.3 analysis software was used for data analysis.Results:A total of 6 Chinese literatures were included. Meta-analysis results showed that there was no statistically significant difference in Pittsburgh Sleep Quality Index (PSQI) score reduction by auricular acupoint pressing compared with estazolam ( WMD=-0.06, 95% CI: -0.96-0.84, P=0.90) .Auricular acupoint pressing was better than Anshen Buxin capsule in reducing PSQI score ( WMD=-5.16, 95% CI: -7.37--2.95, P<0.000 01) . Auricular acupoint pressing could effectively improve perimenopausal insomnia, and the difference was statistically significant ( RR=1.19, 95% CI: 1.08-1.31, P=0.000 4) . Auricular acupoint pressing with beans combined with oral modified Huanglian Ejiao Decoction was better than oral modified Huanglian Ejiao Decoction alone in reducing Athens Insomnia Scale (AIS) scores ( WMD=-2.60, 95% CI: -4.42--0.78, P=0.005) . Compared with modified Chaihu Guizhi Longgu Muli Decoction treatment, auricular acupoint pressing combined with modified Chaihu Guizhi Longgu Muli Decoction could effectively reduce the modified Kupperman score ( WMD=-4.07, 95% CI: -6.36--1.78, P=0.000 5) . In terms of reducing the scores of the social support scale, there was no statistically significant difference between the auricular acupoint pressing with beans and estazolam ( WMD=-0.16, 95% CI: -1.26-0.94, P=0.78) . Conclusions:Auricular acupoint pressing has advantages in improving the total effective rate, reducing PSQI score and AIS score and improving Kupperman score. Limited by the quantity and quality of the included literatures, more large-sample high-quality studies with long-term follow-ups are needed for verification.

Objective:To systematic review the efficacy and safety of external application of traditional Chinese medicine on treatment of breast cancer related lymphedema.Methods:CNKI, Wanfang Data, VIP, Sino-Med, The Cochrane Library, PubMed, Web of Science were searched for related randomized controlled trials, the retrieval time was from inception to May 25, 2020. Two researchers independently screened and evaluated the included studies. Meta-analysis was performed by RevMan 5.4 software.Results:A total of 16 studies involving 1 315 patients with breast cancer related lymphedema were included, and the methodological quality of the included studies was not high. Compared with conventional treatment, external application of traditional Chinese medicine combined with conventional treatment had advantages in improving the total efficiency( P<0.01) and quality of life( P<0.01), reducing pain( P<0.01) and improving upper limb function( P<0.01), without obvious adverse reactions( P>0.05), but there was no improvement in depression( P>0.05). Compared with conventional treatment, external application of traditional Chinese medicine could improve the total efficiency( P<0.01). Compared with placebo sticker combined with conventional treatment, external application of traditional Chinese medicine combined with conventional treatment can reduce circumference( P<0.05) and reduce pain( P<0.01), without obvious adverse reactions( P>0.05). Conclusions:Available evidence suggests that external application of traditional Chinese medicine may be a potential treatment method for breast cancer related lymphedema. Due to the poor methodological quality of the included studies, high-quality randomized controlled trials are still needed.

Objective To investigate the protective effect of inhibition of adenosine monophosphate activated protein kinase (AMPK) on blood brain barrier (BBB) and its mechanism in hypoxic/ischemic models.Methods Two hundred healthy male SD rats were randomly divided into sham-operated group,model group (ischemia 2 h-reperfusion 0,24 and 72 h [I/R]),and Compound C treated group (giving intraperitoneal injection of 20 mg/kg AMPK specific inhibitor Compound C).Focal cerebral ischemia rat models were established by occluding the middle cerebral artery (MCAO).Neurological deficit was determined by Zea Longa test,infarct size and brain water content were measured by TTC staining,leakage of BBB was determined by Evans blue (EB) staining.Expressions of matrix metalloproteinase (MMP)-2/MMP-9 and nuclear factor (NF)-κB,and release of inflammatory factors were detected by Western blotting.Results As compared with those in the model group,significantly reduced neurological deficit scores in Compound C treated group were noted at I/R 0,24 and 72 h (P＜0.05).After I/R 72 h,Compound C treated group had significantly reduced brain infarct size,brain water content and EB leakage as compared with model group (P＜0.05).The expressions of MMP2/MMP9 in model group (52.58±8.12 and 33.15±6.45) were significantly higher than those in the Compound C treated group (21.20±3.39 and 15.46±4.71,P＜0.05).What is more,as compared with the model group,Compound C treated group had significantly reduced expressions of NF-κB and inflammatory factors (P＜0.05).Conclusions Inhibition of AMPK shows a protective role in BBB after ischemic injury,mainly by inhibiting NF-κB signaling pathway,inhibiting the expression of MMP-2/MMP-9 to reduce the degradation of the base metal film,and maintain the integrity of BBB,thus,improving the ischemic symptoms,reducing the brain water content and reducing infarct size.
