Objective:To investigate the current prevalence and control status of coal-burning-borne endemic fluorosis in key areas of the disease in Zhenxiong County of Yunnan Province, thereby providing scientific basis for formulating subsequent prevention strategies and measures.Methods:From October to November 2023, a simple random sampling method was used to conduct a survey in three key townships (towns) in Zhenxiong County, Chishuiyuan Town, Yanyuan Town, and Linkou Yi and Miao Ethnic Township. Three administrative villages were selected from each township (town) as survey sites, and dental fluorosis examination on children aged 8 - 12 years who were born and lived in the local area was conducted. Thirty households were selected from each survey site, the use of household stoves and the formation of related healthy living behaviors were investigated. At the same time, a survey was conducted among primary school students and housewives to investigate their knowledge of coal-burning-borne endemic fluorosis prevention and control. The control and elimination of endemic areas were evaluated according to the "Assessment Protocol for Control and Elimination of Key Endemic Diseases (2019 Edition)".Results:A total of 1 172 children were examined, and the detection rate of dental fluorosis was 7.76% (91/1 172), with a dental fluorosis index of 0.11. A total of 295 households were investigated, and the qualified improved stoves rate and the correct use rate of qualified improved stoves were 95.59% (282/295) and 100% (282/282), respectively. The correct drying rate of edible corn and chili peppers was 79.66% (235/295). The awareness rates of coal-burning-borne endemic fluorosis prevention and control knowledge among housewives and primary school students were 46.69% (409/876) and 82.49% (440.5/534), respectively. Among the 9 villages investigated, two villages had met the criteria for eliminating endemic disease areas, two villages had met the criteria for controlling endemic disease areas, and the remaining 5 villages were uncontrolled.Conclusions:After implementing the comprehensive prevention and control measures mainly based on changing stoves, coal-burning-borne endemic fluorosis condition in Zhenxiong County has been effectively controlled, but there is still a significant gap between the elimination goals of some endemic fluorosis areas. Therefore, it is necessary to continue to strengthen prevention and control measures and promote health education.

Stroke is one of the main diseases that threaten human health,including ischemic stroke and hemorrhagic stroke,with the former being the main cause.The important pathogenesis of ischemic stroke includes neuroinflammation,oxidative stress,and excitatory toxic damage,and neuroinflammation plays an impor-tant role in the pathogenesis and rehabilitation process of ische-mic stroke.Microglia are inherent immune cells in the central nervous system,which monitor the site of injury and respond to the immune response as soon as a stroke occurs.The activated microglia are mainly polarized into pro-inflammatory M1 type and anti-inflammatory M2 type.The latter improves neurological dys-function by inhibiting neuroinflammation,promoting neuronal re-generation and myelin repair,and maintaining the integrity of the blood-brain barrier.It suggests that it may be a potential target for treating ischemic stroke by combating acute phase injury and promoting chronic phase rehabilitation.Precise regulation of M1/M2 activation has important therapeutic value in cerebral protection in ischemic stroke.This article focuses on the role of M2 microglia in ischemic stroke and the mechanism of various drugs or acupuncture and moxibustion therapy regulating the transformation of microglia into M2 type,in order to provide theo-retical basis for clinical treatment of stroke and new drug devel-opment.

Aim To verify the therapeutic effect of the Qushi Huoxue decoction(QSHXF)on a mouse model of non-alcoholic fatty liver disease(NAFLD)using network pharmacology and experimental approaches,to examine the changes in the PI3K-AKT-lipid metabo-lism signaling pathway,and to elucidate its molecular mechanisms.Methods The potential active ingredi-ents and targets of the QSHXF were identified using the TCMSP platform.NAFLD-related genes were sourced from the GeneCards,PharmGkb,TTD,and OMIM data-bases.The intersection of drug targets and NAFLD treatment targets was analyzed to identify the key tar-gets of the QSHXF in treating NAFLD.The STRING database and Cytoscape 3.9.1 software were utilized to construct networks linking traditional Chinese medicine active ingredients to disease targets and PPI networks,allowing for the screening of key active ingredients and core targets.GO and KEGG enrichment analyses of the intersecting targets were conducted using R version 4.2.2.The NAFLD model was established by feeding mice a methionine-choline deficient diet for a duration of five weeks.Following successful modeling,low,me-dium,and high doses of the QSHXF were administered for intervention over a period of six weeks.The efficacy was verified and the underlying mechanisms were ex-plored using methods such as HE staining,Oil Red O staining,and Western blot analysis.Results The net-work pharmacology prediction indicated that QSHXF might effectively treat NAFLD through key components such as quercetin and kaempferol,as well as core tar-gets including STAT3,AKT1,and HIF1A.KEGG en-richment analysis further suggested that QSHXF might exert its therapeutic effects on NAFLD via signaling pathways such as AGE-RAGE and PI3K-AKT.Verifi-cation through animal experiments demonstrated that QSHXF could significantly reduce hepatic steatosis and lipid droplet accumulation in NAFLD mice.Specifical-ly,it markedly decreased serum levels of TC,TG,ALT,AST,and LDL,while increasing HDL levels.Addition-ally,the treatment significantly reduced the protein ex-pression levels of p-PI3K,p-AKT,SREBP-1c,FASN,and ACC1 in the liver.Conclusions QSHXF can sig-nificantly enhance liver function,improve blood lipid levels,and alleviate hepatic steatosis in NAFLD mice,with its mechanism potentially linked to the inhibition of the PI3K-AKT-lipid metabolism signaling pathway.

OBJECTIVE To evaluate the application effect of implementation strategies in the prevention and control of sur-gical site infection(SSI),and to review its research progress.METHODS A scoping review method was employed,invol-ving systematic searches across databases such as Web of Science,PubMed,Cochrane,CNKI and Wanfang.After screening based on the inclusion and exclusion criteria,the included literature was analyzed and reported in a standard-ized manner.RESULTS A total of 47 articles were included.Most studies adopted comprehensive evidence-based practices(EBP)(≥2 types)and employed multimodal implementation strategies(≥3 items)to facilitate the implementation of SSI prevention and control EBP.Within the framework of the WHO multimodal strategy,42,39,39 and 24 studies re-spectively applied the four implementation strategies of system change,education and training,monitoring and feedback and reminder and communication,while only 9 studies applied the strategy of creating a safety culture.The highest pro-portion of studies(31.91％,15/47)employed a combination of four implementation strategies,with the common combi-nation being"system change+education and training+monitoring and feedback+reminder and communication"(29.79％,14/47),and this combination of four implementation strategies demonstrated outstanding performance in en-hancing EBP compliance.Totally 26(55.32％)showed decrease in the incidence of SSI after intervention(P＜0.05).CONCLUSIONS Implementation strategies are crucial for the successful implementation of SSI prevention and con-trol EBP.Multimodal implementation strategies are common approaches to facilitate the implementation of EBP.In the future,it is necessary to further standardize the application of scientific methods and improve the effect evaluation of im-plementation strategies,providing a reference for the sustained and widespread application of EBP in clinical practice.

AIM To investigate the protective effect of Sanfeng Tongqiao Dropping Pills against house dust mite(HDM)-induced allergic asthma in mice.METHODS Compared to the intact BALB/c mice in the blank control group,the BALB/c mice randomly assigned into the model group,the dexamethasone group(0.67 mg/kg),and the low-dose,medium-dose,and high-dose Sanfeng Tongqiao Dropping Pills groups(15,30 and 60 mg/kg),were induced into acute allergic asthma models via weekly intraperitoneal sensitization with 0.1 mL HDM solution(0.5 mg/mL)for three weeks followed by three consecutive daily intranasal challenges with 10 μL HDM solution(2.5 mg/mL)starting in the third week.The drug administered continuously 7 days after the last excitation.The mice had their airway reactive Penh value detected,their pulmonary pathological changes observed by HE staining,their blood eosinophils(EOS)counted,their Th2 cytokines in lung tissue and serum IgE levels detected by ELISA,and their number of peripheral blood mononuclear cells(PBMC)and pulmonary Th2 cells detected by flow cytometry.Chronic allergic asthma was induced in grouped BALB/c mice through repeated intranasal challenges with 10 μL HDM solution(2.5 mg/mL)administered five times weekly for five consecutive weeks.Drug treatment continued for 14 days following the final challenge.After the final treatment,the mice had their pulmonary pathological changes observed by HE staining,and their levels of Th2 cytokines in B ALF and lung tissue and serum IgE detected by ELISA.RESULTS Compared to the blank control group,the acute allergic asthma model group exhibited increases in Penh value,EOS count and IgE level in serum,IL-4 and IL-5 levels in lung tissue(P＜0.01);obvious pulmonary inflammatory cells infiltration,and thickened airway wall;and increase in pulmonary number of Th2 cells(P＜0.01).Compared to the model group,the groups intervened with Sanfeng Tongqiao Dropping Pills demonstrated decreased Penh value,serum EOS count,IgE level and IL-5 level in lung tissue(P＜0.05,P＜0.01);reduced pulmonary inflammatory infiltration and alleviated airway wall thickening;and decreased number of pulmonary Th2 cells.Compared to the blank group,the chronic allergic asthma model group showed obvious pulmonary inflammatory infiltration and airway wall thickening;and increased EOS count and IgE level in serum,IL-4 and IL-13 in lung tissue and IL-14 in BALF(P＜0.05,P＜0.01).Compared to the model group,the groups intervened with either medium-dose or high-dose Sanfeng Tongqiao Dropping Pills demonstrated reduced pulmonary inflammatory infiltration;and decreased serum EOS count,IgE level,IL-13 in lung tissue and IL-14 in BALF(P＜0.05,P＜0.01).CONCLUSION Sanfeng Tongqiao Dropping Pills reduce Th2 cells in peripheral blood and lung tissue,suppress type 2 inflammation,and thereby alleviate allergic asthma.

Objective:This study aimed to analyze the infection status of viral viruria within one year after kidney transplantation, its impact on renal allograft function, and associated risk factors.Methods:A retrospective case-control study was conducted, involving 370 patients who underwent allogeneic kidney transplantation at Renji Hospital, Shanghai Jiao Tong University School of Medicine, from January 1, 2020 to December 31, 2021. Urinary viral loads of BK virus (BKV), JC virus (JCV), cytomegalovirus (CMV), and Epstein-Barr virus (EBV) were detected using PCR fluorescent probe assays. Patients were categorized into infection and non-infection groups. Glomerular filtration rate (GFR) and tacrolimus trough concentration was measured during infections, and clinical data were collected. Univariate analysis was performed to identify risk factors for viral viruria.Results:The 1-year patient survival rate and graft survival rate were both 98.6%. The incidence rates of viral viruria were as follows: JCV (42.7%), BKV (29.7%), CMV (11.6%), and EBV (2.9%), with statistically significant differences among viruses ( P<0.001). Single viral infection accounted for 48% of cases, while co-infections were predominantly BKV+JCV (9%). JCV infection rates remained consistently high throughout the year (22.4%-28.9%), whereas BKV infections peaked at 3 months postoperatively (20.5%). Co-infection with low-load JCV (>2 000 copies/ml) and CMV (>6 000 copies/ml) led to a significant decline in GFR at 6 months post-transplantation [median difference: 16.7 ml/(min×1.73 m2), P=0.019]. Univariate analysis revealed that elevated tacrolimus trough concentration was independent risk factor for BKV (4.90 vs. 4.30 ng/ml, Z=4.29, P<0.001) and JCV infections (5.30 vs. 4.80 ng/ml, Z=4.25, P<0.001). Conclusion:High incidences of JCV and BKV infections were observed post-kidney transplantation. Co-infection with low-load JCV and CMV accelerates renal function impairment, highlighting the critical role of tacrolimus concentration management in reducing viral infection risks.
