Objective: To summarize strategies for improving childhood hypertension, so as to provide evidencebased recommendations for poliymaking and practice childhood hypertension management in China. Methods: From March to April 2024, child health stakeholders from five districts in Hangzhou were selected using a combination of stratified and convenience sampling methods. Data were analyzed using a groundedtheory approach. During the indepth interview phase, six policymakers were interviewed. Focus group discussions were conducted with school administrators, healthcare providers, and parents, comprising a total of 62 participants. Results: Through threelevel coding, 116 initial categories were identified(e.g., "trend of younger age" "difficulty in behavior change"), 35 main categories (e.g., "higher incidence compared to the past" "caused by comprehensive influencing factors"), and 12 core categories (e.g., "epidemic status" "influencing factors"). Finally, the cognitive status, problem analysis, and management strategies of children hypertension were constructed. Conclusion Effective prevention and control of childhood hypertension requires coordinated efforts among governments, schools, families, and society to establish a comprehensive management system, with dynamic monitoring and evaluation to optimize policy implementation.

Objective: The impact of prophylactic salpingectomy on the prevention of epithelial ovarian cancer (EOC) remains unclear, particularly in Asian populations where data is lacking. In this systematic review and meta-analysis study, we sought to assess whether prophylactic salpingectomy could reduce the incidence of ovarian cancer in the general population of multiple ethnicities. Methods: A systematic review and meta-analysis were conducted using PubMed/MEDLINE, EMBASE, the Cochrane Library, and Web of Science to assess the effectiveness of salpingectomy, bilateral salpingectomy (BS), and unilateral salpingectomy (US) in reducing the risk of EOC and evaluating postoperative outcomes. Results: The final analyses included 6 eligible trials (5,747,056 patients), including 1 cohort study and 5 case-control studies. The analyses of these studies demonstrated that women who underwent salpingectomy had a significantly reduced risk of EOC compared to those who did not receive salpingectomy (odds ratio [OR]=0.63; 95% confidence interval [CI]=0.45–0.89; p=0.007). Five studies (5,746,469 patients) indicated a significant reduction in EOC risk among patients who underwent BS (OR=0.48; 95% CI=0.33–0.69; p<0.001).On the other hand, in the analysis of 4 studies (5,745,887 patients) that examined US, the association with EOC risk was not significant despite the protective trend (OR=0.82; 95% CI=0.64–1.06; p=0.12). Conclusion Our results indicate BS is an effective strategy for reducing the risk of sporadic EOC, but the results did not lead to the same conclusion for patients who underwent US. When a candidate or patient is undergoing a hysterectomy or has other benign diseases, prophylactic BS may be a safe surgical procedure that carries future benefits in terms of EOC risk.

Objective: To investigate the association between plant-based diet and different types of obesity, so as to provide references for obesity prevention. Methods: Residents aged 35-75 years from 33 counties (cities, districts) in Zhejiang Province were selected as study subjects using a multistage stratified random sampling method between April and December 2024. Demographic information and living behaviors were collected using questionnaire surveys. Height, weight and waist circumference were measured, and body mass index (BMI) was calculated. BMI ≥28.0 kg/m2 was defined as obesity, waist circumference ≥90 cm in males or ≥85 cm in females was defined as central obesity, and individual with obesity who also had central obesity was defined as having compound obesity. Food intake over a 3-day period was collected using the consecutive 3-day 24-hour dietary recall method. The plant diet index (PDI), healthful plant diet index (HPDI), and unhealthful plant diet index (UPDI) were calculated, and categorized into quintiles (Q1-Q5) based on their distribution. Association between the PDI, PDI, UPDI and different types of obesity were analyzed using multivariable logistic regression models. Results: A total of 4 882 individuals were surveyed, including 2 233 males (45.74%) and 2 649 females (54.26%). The average age was (55.42±12.14) years. There were 537 individuals of obesity, 1 718 individuals of central obesity, and 500 individuals of compound obesity, with detection rates of 11.00%, 35.19%, and 10.24%, respectively. Multivariable logistic regression analysis showed that, after adjusting for demographic information and living behaviors, compared with Q1 group, HPDI Q5 group showed a 29.6% lower risk of obesity (OR=0.704, 95%CI: 0.525-0.943) and a 32.1% lower risk of compound obesity (OR=0.679, 95%CI: 0.502-0.918). Conversely, the UPDI Q5 group exhibited a 39.5% higher risk of obesity (OR=1.395, 95%CI: 1.032-1.886) and a 39.8% higher risk of compound obesity (OR=1.398, 95%CI: 1.025-1.907). No statistically significant association was found between PDI and obesity, central obesity, and compound obesity (all P>0.05). As HPDI increased, the risks of obesity and compound obesity showed decreasing trends; as UPDI increased, the risks of obesity and compound obesity showed increasing trends (all Ptrend<0.05). Conclusion A healthful plant-based diet is associated with reduced risks of obesity and compound obesity, while an unhealthful plant-based diet is associated with increased risks of obesity and compound obesity.

Objective To explore the effect of miR-296-3p on hepatic fibrosis induced by bile duct ligation(BDL)in rats.Methods 25 SD rats were randomly divided into sham group,model(BDL)group,NC adv group,miR-296-3p adv group and miR-296-3p sponge adv group,with 5 rats in each group.The pathological changes were ob-served in rat liver tissue via HE,Masson and Sirius Red staining;the levels of alanine aminotransferase(ALT),aspartate aminotransferase(AST)and total bilirubin(TBIL)in the serum of rat in each group were detected;the expression levels of miR-296-3p,interleukin(IL)-6,IL-1 β,tumor necrosis factor(TNF)-α and smooth muscle actin(α-SMA),type Ⅰ collagen(Col1A1),and connective tissue growth factor(CTGF)mRNA in rat liver tissue were detected by qRT-PCR;the expression levels of α-SMA,Col1A1 and CTGF proteins were detected by Western blot.Immunohistochemical staining(IHC)was performed to detect the expression of α-SMA in liver tissue.Target genes of miR-296-3p was predicted by bioinformatic analysis using the online database.Zinc finger and BTB do-main-containing protein20(ZBTB20)mRNA and protein expression levels were detected.Results The pathologi-cal staining results showed that compared with sham group,a large number of infiltrated inflammatory cells and col-lagen deposition were observed in the liver tissues of rats in the BDL group and NC adv group.Compared with NC adv group,the inflammatory cells and collagen deposition decreased in the liver tissues of miR-296-3p adv group.However,in miR-296-3p sponge adv group,collagen product and inflammatory reaction increased.Compared with sham group,the contents of ALT,AST and TBIL in serum of rats in BDL group and NC adv group increased,the expression level of miR-296-3p decreased,the mRNA expression levels of IL-6,IL-1β,TNF-α increased,and the mRNA and protein expression levels of α-SMA,Col1A1 and CTGF increased(all P＜0.05).Compared with the NC adv group,the contents of ALT,AST and TBIL in serum of rats in miR-296-3p adv group decreased,the ex-pression level of miR-296-3p increased,the mRNA expression levels of IL-6,IL-1 β and TNF-α,and the mRNA and protein expression levels of α-SMA,Col1A1 and CTGF in liver tissues decreased(all P＜0.05).The results of miR-296-3p sponge adv group were opposite to those of miR-296-3p adv group(all P＜0.05).The bioinformat-ics website predicted that ZBTB20 might be a candidate target gene of miR-296-3p.Compared with sham group,the expression of ZBTB20 mRNA and protein in the liver tissues of BDL group and NC adv group increased(P＜0.05),and the expression of ZBTB20 in the liver tissues of miR-296-3p adv group decreased compared with NC adv group(P＜0.05).However,the expression of ZBTB20 in liver tissues of miR-296-3p sponge adv group in-creased(P＜0.05).Conclusion miR-296-3p expression decreases in BDL-induced hepatic fibrosis in rats,and miR-296-3p may inhibit hepatic fibrosis in BDL rats by targeting ZBTB20.

Objective To investigate the effect of miR-199a-5p on common bile duct ligation(BDL)-induced liver fibrosis in rats by regulating intestinal flora.Methods The 25 SD rats were randomly divided into five groups:the Sham group,the BDL group,the negative control adenovirus(NC adv)group,the miR-199a-5p adv group and the miR-199a-5p sponge adv group.The pathological changes of liver tissue and the degree of liver fibrosis were ob-served by HE,Masson and Sirius Red staining.The levels of aspartate aminotransferase(AST),alanine amin-otransferase(ALT),total bilirubin(TBIL)and direct bilirubin(DBIL)in serum of rats were determined by a fully automatic biochemical analyzer.The mRNA expression level of miR-199a-5p in liver tissue of rats was detec-ted by qRT-PCR.The protein expression levels of α-smooth muscle actin(α-SMA)and collagen type 1 alpha 1(COL1A1)in liver tissue of rats were detected by double immunofluorescence staining and Western blot experi-ment.Rat feces were collected for 16S rRNA high-throughput sequencing.Results The expression of miR-199a-5p was up-regulated in the liver tissue of BDL rats(P＜0.01).Compared with the NC adv group,the degree of liver injury and collagen deposition were relatively serious,the levels of AST,ALT,TBIL and DBIL in serum and the expression levels of α-SMA and COL1A1 in liver tissue increased in the miR-199a-5p adv group(all P＜0.05).However,the results of miR-199a-5p sponge adv intervention were opposite(all P＜0.05).The 16S rRNA sequencing results showed that rats treated with miR-199a-5p adv were characterized by increased diversity and richness of intestinal microbiota,changed composition of intestinal microbiota,while the results of miR-199a-5p sponge adv interfering with the bacterial community were opposite(all P＜0.05).Conclusion miR-199a-5p promotes liver fibrosis of BDL rats,and its mechanism may be related to regulating the diversity and abundance of intestinal microbiota.

ObjectiveThe human angiotensin converting enzyme2 （hACE2） transgenic mouse model was used to clarify the antiviral efficacy of BD-77 against a novel coronavirus SARS-CoV-2 and explore the action mechanism of BD-77 against SARS-CoV-2. MethodSARS-CoV-2 Omicron and Delta variant strains-infected VeroE6 cell models were established and administered with BD-77 to observe the antiviral effect of BD-77 in vitro. A kit was used to detect the effect of BD-77 in vitro on the binding of spike S protein of SARS-CoV-2 virus （Delta/Omicron） to angiotensin converting enzyme2 （ACE2）. Chromatography was adopted to detect the binding of BD-77 to the S protein and N protein of the novel coronavirus. hACE2 transgenic C57BL/6 mice were divided into a blank control group， SARS-CoV-2 infection group， BD-77 administration groups of 37.5 mg·kg^-1 and 75 mg·kg^-1， with eight mice in each group. The pneumonia model of SARS-CoV-2-infected hACE2 transgenic mice was built to observe the survival of the mice， detect the virus titer of the lung tissue of the mice， and observe the lesions in the lung tissue. ResultBD-77 had a certain inhibitory effect on Omicron and Delta variant strains in vitro， with median inhibitory concentration （IC₅₀） of 526.3 mg·L^-1 and 653.0 mg·L^-1， respectively. BD-77 had no significant inhibitory effect on the binding of the S protein of WT， Omicron， and Delta variant strains of SARS-CoV-2 to ACE2 and had no binding effect with the S protein and N protein of the novel coronavirus. No mice in the blank group died， while the mortality rate of SARS-CoV-2-infected mice was 75%. There was a large amount of virus replication in the lung tissue of the mice and large areas of inflammatory infiltration in the lung tissue and interstitium. Compared with the model group， BD-77 administration groups of 37.5 mg·kg^-1 and 75 mg·kg^-1 could reduce the mortality of mice， significantly lower the virus titer in the lung tissue of mice （P<0.05）， and improve lung lesions. ConclusionBD-77 demonstrated significant inhibitory effects against SARS-CoV-2 virus in vitro and in vivo. However， its mechanism of action did not involve direct inhibition of the virus itself or intervention in the virus-host binding process. This finding suggests that the mechanism of action of BD-77 needs to be thoroughly investigated and elucidated by further experiments.
