Aim To explore the key components and mechanisms of Lizhong decoction in treating rats with cold-damp diarrhea based on network pharmacology,molecular docking technology and animal experiments.Methods By literature review and database collec-tion,the components of Lizhong decoction,therapeutic targets,and the mapping with diarrhea disease targets were conducted to construct an intersection target pro-tein-protein interaction network for screening core tar-gets,and GO and KEGG pathway enrichment analysis was performed to build an"active component-target-pathway"network,followed by molecular docking vali-dation.Forty-eight rats were randomly divided into the normal control group(K),model group(DG),Lizhong decoction group(LZDG),and Pulsatilla decoction group(BTDG).Subsequently,a rat cold-damp diar-rhea model was established using Senna combined with low-temperature high-humidity environment,and the rats were intervened with Lizhong decoction and Pul-satilla decoction.HE staining was used to detect path-ological changes in intestinal tissue,ELISA was em-ployed to measure the levels of peripheral blood IL-6,IL-10,IL-1 β,and TNF-α,and western blot was used to determine the expression of colon tight junction pro-teins.Results Network pharmacology initially identi-fied 125 compounds in Lizhong decoction,5 186 drug target components,438 disease targets,and 60"drug-disease"shared targets.GO and KEGG enrichment a-nalysis showed that signaling pathways such as IL-17 and TNF were highly enriched.Molecular docking in-dicated that the core components of the drug had good binding activity with corresponding key targets.Liz-hong decoction could effectively improve the clinical symptoms of rats with cold-damp diarrhea,and com-pared with the DG group,the diarrhea rate,diarrhea in-dex,and other related indicators also gradually de-creased to normal levels.Compared with the DG group,the LZDG group showed reduced inflammation levels and a recovery in energy metabolism levels.Conclusion It can regulate targets such as MMP9 and IL-17 signaling pathways through multi-components like Calycosin and formononetin to exert its therapeutic effect on cold-damp diarrhea.

BACKGROUND: The use of inserted sham acupuncture as a placebo in randomized controlled trials (RCTs) is controversial, because it may produce specific effects that cause an underestimation of the effect of acupuncture treatment. OBJECTIVE: This systematic survey investigates the magnitude of insert-specific effects of sham acupuncture and whether they affect the estimation of acupuncture treatment effects. SEARCH STRATEGY: PubMed, Embase and Cochrane Central Register of Controlled Trials were searched to identify acupuncture RCTs from their inception until December 2022. INCLUSION CRITERIA: RCTs that evaluated the effects of acupuncture compared to sham acupuncture and no treatment. DATA EXTRACTION AND ANALYSIS: The total effect measured for an acupuncture treatment group in RCTs were divided into three components, including the natural history and/or regression to the mean effect (controlled for no-treatment group), the placebo effect, and the specific effect of acupuncture. The first two constituted the contextual effect of acupuncture, which is mimicked by a sham acupuncture treatment group. The proportion of acupuncture total effect size was considered to be 1. The proportion of natural history and/or regression to the mean effect (PNE) and proportional contextual effect (PCE) of included RCTs were pooled using meta-analyses with a random-effect model. The proportion of acupuncture placebo effect was the difference between PCE and PNE in RCTs with non-inserted sham acupuncture. The proportion of insert-specific effect of sham acupuncture (PIES) was obtained by subtracting the proportion of acupuncture placebo effect and PNE from PCE in RCTs with inserted sham acupuncture. The impact of PIES on the estimation of acupuncture's treatment effect was evaluated by quantifying the percentage of RCTs that the effect of outcome changed from no statistical difference to statistical difference after removing PIES in the included studies, and the impact of PIES was externally validated in other acupuncture RCTs with an inserted sham acupuncture group that were not used to calculate PIES. RESULTS: This analysis included 32 studies with 5492 patients. The overall PNE was 0.335 (95% confidence interval [CI], 0.255-0.415) and the PCE of acupuncture was 0.639 (95% CI, 0.567-0.710) of acupuncture's total effect. The proportional contribution of the placebo effect to acupuncture's total effect was 0.191, and the PIES was 0.189. When we modeled the exclusion of the insert-specific effect of sham acupuncture, the acupuncture treatment effect changed from no difference to a significant difference in 45.45% of the included RCTs, and in 40.91% of the external validated RCTs. CONCLUSION The insert-specific effect of sham acupuncture in RCTs represents 18.90% of acupuncture's total effect and significantly affects the evaluation of the acupuncture treatment effect. More than 40% of RCTs that used inserted sham acupuncture would draw different conclusions if the PIES had been controlled for. Considering the impact of the insert-specific effect of sham acupuncture, caution should be taken when using inserted sham acupuncture placebos in RCTs.

AIM To study the effects of Dianxianqing Granules on Tau protein in a mouse model of Alzheimer's disease (AD).METHODS The mice expressing P301S mutant Tau variant were randomly divided into the model group,the MCC950 group (NLRP3 inhibitor,10 mg/kg),the Dianxianqing Granules group (12.48 g/kg),the MCC950+Dianxianqing Granules group,in contrast to the C57BL/6 mice of the control group.After 5 months of administration,the mice had their learning and memory ability tested by Y maze test and Morris water maze test;their cerebral morphological changes observed by HE staining;their cerebral expressions of Caspase-1 and GSDMD proteins detected by immunohistochemical method;their expression of cerebral Tau protein detected by immunofluorescence;and their cerebral expressions of Tau,p-Tau (ser202),p-Tau (thr205),NLRP3,Caspase-1,IL-1β and IL-18 detected by Western blot.RESULTS Compared with the control group,the model group displayed decreased rate of spontaneous alternate reaction and times of crossing platform (P<0.05,P<0.01);abnormal hippocampal morphology,decreased number of neurons,increased cerebral positive expressions of Caspase-1 and GSDMD (P<0.05);deposition of a large number of brown granules in cytoplasm,and increased protein expressions of Tau,p-Tau (ser202),p-Tau (thr205),NLRP3,Caspase-1,IL-1βand IL-18 in the hippocampus and the cortex (P<0.05,P<0.01).Compared with the model group,the group intervened with Dianxianqing Granules demonstrated both increased rate of spontaneous alternate reaction and times of crossing platform (P<0.05);complete and normal morphology of the brain,a diversity of fine neurons,reduced cerebral positive expressions of Caspase-1 and GSDMD (P<0.05);and decreased protein expressions of Tau,p-Tau (ser202),p-Tau (thr205),NLRP3,Caspase-1,IL-1β and IL-18 in the hippocampus and the cortex (P<0.05,P<0.01).CONCLUSION Dianxianqing Granules may inhibit Tau protein expression in the mouse model of AD via NLRP3/Caspase-1 pathway.

Objective:To investigate the effects of visualized precision electrophysiological diagnosis and transcutaneous low-frequency electrical stimulation(TES)on hypoxia-induced ED in high-altitude areas.Methods:This study included 152 ED pa-tients from high-altitude hypoxic areas treated by TES based on the parameters obtained from visualized precision electrophysiological diagnosis.We followed up the patients for 1 to 3 months and compared their ⅡEF-5 scores,nocturnal penile tumescence and rigidity(NPTR)and infrared thermal metabolic technology(TMT)-based temperature of the whole body and diseased parts before and after treatment.Results:All the patients successfully completed 1 to 3 courses of TES.There were no statistically significant differences in the ⅡEF-5 scores(P＜0.05)and penile tip optimal erection rigidity and duration(P＜0.01)of the patients before and after treat-ment.TMT images indicated a temperature change of＞1.5 ℃ in the penis and bilateral inguinal regions after treatment,suggesting the effectiveness of electrical stimulation.No recurrence was observed during the follow-up.Conclusion:TES based on the parame-ters obtained from visualized precision electrophysiological diagnosis has a definite effect on hypoxia-induced ED by enhancing oxygen supply to the penile corpus cavernosum and improving its function and structure.

Objective To observe the effect of Bushen Jianpi Prescription,a prescription with the actions of tonifying the kidney and strengthening the spleen,combined with short-term intensive insulin therapy on dedifferentiation of pancreatic beta-cells in patients with type 2 diabetes mellitus(T2DM)of spleen and kidney deficiency type.Methods Seventy patients with T2DM of spleen and kidney deficiency type were randomly divided into control group and observation group,with 35 cases in each group.The control group was treated with intensive insulin therapy,and the observation group was treated with Bushen Jianpi Prescription on the basis of treatment for the control group.The course of treatment lasted for 2 weeks.The changes of TCM syndrome score,and levels of blood glucose,serum high mobility group protein B1(HMGB1),interleukin 1β(IL-1β),tumor necrosis factor α(TNF-α)and the ratio of proinsulin to insulin(PI/I)in the two groups were observed before and after treatment.Results(1)During the treatment,one case in the control group and 2 cases in the observation group fell off.Eventually,34 cases in the control group and 33 cases in the observation group were included in the efficacy statistics.(2)After treatment,the scores of TCM syndromes in the two groups were significantly lower than those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the levels of fasting plasma glucose(FPG)and 2-hour postprandial plasma glucose(2hPG)in the two groups were significantly lower than those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the level of HMGB1 in the two groups was significantly lower than that before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(5)After treatment,the serum levels of inflammatory factors of IL-1β and TNF-α in the two groups were significantly lower than those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(6)After treatment,the PI/I ratio of the two groups was significantly lower than that before treatment(P＜0.05),and the decrease of the observation group was significantly superior to that of the control group(P＜0.05).Conclusion Bushen Jianpi Prescription combined with short-term intensive insulin therapy can effectively improve the islet function of patients with T2DM of spleen and kidney deficiency type.The mechanism may be related to the relief of high-glucose toxicity and the decrease of the inflammatory factor levels,thus to inhibit the dedifferentiation of pancreatic beta-cells.

A crucial lesson gained through the pandemic preparedness and response to COVID-19 is that all measures for epidemic control must be law-based. The legal system is related not only to public health emergency management per se but also to all aspects of the institutional supporting system throughout the lifecycle. Based on the lifecycle emergency management model, this article analyses the problems of the current legal system and the potential solutions. It is suggested that the lifecycle emergency management model shall be followed to establish a more comprehensive public health legal system and to gather the intelligence and consensus of experts with different expertise, including epidemiologists, sociologists, economists, jurist and others, which will collaboratively promote the science-based legislation in the field of epidemic preparedness and response for the establishment of a comprehensive legal system for public health emergency management and with Chinese characteristics.
