ObjectiveTo investigate the efficacy of Xingpi capsules (XPC) in treating diarrhea-predominant irritable bowel syndrome (IBS-D) with spleen deficiency and elucidate its potential molecular mechanisms. MethodsA rat model of IBS-D with spleen deficiency was established by administering senna leaf in combination with restrained stress and swimming fatigue for 14 d. Ten specific pathogen free (SPF)-grade healthy rats were used as the normal control group. After successful modeling, SPF-grade rats were randomly divided into a model group, a pinaverium bromide group (1.5 mg·kg-1), and low- and high-dose XPC groups (0.135 and 0.54 g·kg-1), with 10 rats in each group. Rats in the normal control group and the model group were given distilled water by gavage, while the remaining groups were administered corresponding drug solutions by gavage once a day for 14 consecutive days. The rat body weights and fecal condition were observed every day, and the Bristol score was recorded. Enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of 5-hydroxytryptamine (5-HT) in serum and colon tissue. Transmission electron microscopy was used to observe the microvilli and tight junctions in the colon. The integrity of the colonic barrier, intestinal motility, and expression of related pathway proteins were evaluated by hematoxylin-eosin (HE) staining, immunohistochemistry, and Western blot. ResultsCompared with those in the normal control group, rats in the model group showed a significantly decreased body weight and increased diarrhea rate, diarrhea grade, and Bristol score (P<0.01). HE staining revealed incomplete colonic mucosa in the model group, with evident congestion and edema observed. Electron microscopy results indicated decreased density and integrity of the colonic barrier, shedding and disappearance of microvilli, and significant widening of tight junctions. The expression levels of colonic tight junction proteins Occludin and Claudin-5 were downregulated (P<0.01), and the levels of 5-HT in serum and colon tissue were elevated (P<0.01). The small intestine propulsion rate significantly increased (P<0.01), and the expression of contractile proteins Ras homolog family member A (RhoA) and Rho-associated coiled-coil containing protein kinase 2 (ROCK2) in colon and phosphorylation of myosin light chain (MLC20) were upregulated (P<0.01). Compared with the model group, the treatment groups showed alleviated diarrhea, diarrhea-associated symptoms, and pathological manifestations of colon tissue to varying degrees. Specifically, high-dose XPC exhibited effectively relieved diarrhea, promoted recovery of colonic mucosal structure, significantly reduced congestion and edema, upregulated expression of Occludin and Claudin-5 (P<0.01), decreased levels of 5-HT in serum and colon tissue (P<0.05,P<0.01), significantly slowed small intestine propulsion rate (P<0.01), and significantly downregulated expression of contractile proteins RhoA and ROCK2 in colon and phosphorylation of MLC20 (P<0.05,P<0.01). ConclusionXPC effectively alleviates symptoms of spleen deficiency and diarrhea and regulates the secretion of brain-gut peptide. The characteristics of XPC are mainly manifested in alleviating IBS-D with spleen deficiency from the aspects of protecting intestinal mucosa and inhibiting smooth muscle contraction, and the mechanism is closely related to the regulation of the 5-HT-RhoA/ROCK2 pathway expression.

ObjectiveTo investigate the prevalence of high-risk HPV infection among women in Kashgar area, analyze related risk factors, conduct follow-up and health education interventions for positive cases in the past three years, and assess intervention outcomes to improve HPV screening awareness and reduce cervical cancer incidence. MethodsThis study randomly selected 571 women from Kashgar who underwent HPV screening as part of a health check-up in the First People’s Hospital of Kashgar between January 2021 and June 2023. High-risk HPV-DNA was detected using the PCR-RDB method. Based on the test results, participants were divided into HPV-negative and HPV-positive groups, and the infection rates and associated risk factors were analyzed. Additionally, follow-up was conducted for women who tested positive for high-risk HPV during the screening to assess the effectiveness of health management interventions. ResultsFrom 2021 to 2023, the high-risk HPV positive rate among women in Kashgar showed a year-on-year decline, recorded at 19.15%, 16.43%, and 11.30%, respectively (P<0.001), with a total of 3,921 cases (16.13%) testing positive for high-risk HPV during this period. Uyghur women had a significantly higher infection rate compared with those of Han nationality and other ethnic minorities (P<0.05). Risk factors included age, age at first sexual activity, number of sexual partners, contraceptive methods, and a history of vaginal inflammation (P<0.05). Health management interventions significantly improved participants’ awareness scores regarding cervical cancer prevention and the proportion of women voluntarily receiving HPV vaccination (P<0.05). ConclusionsHigh-risk HPV infection among Uyghur women in Kashgar area is relatively high, with single infection of HPV-16 and HPV-52 and mixed infections of HPV-16 +HPV-52 and HPV-16 +HPV-58 being predominant. Risk factors include age at first sexual activity, number of sexual partners, contraceptive methods, and history of vaginal inflammation. Through triple-education interventions, the incidence of cervical cancer in Kashgar has been effectively reduced, and standards for primary-level diagnosis, treatment, and health supervision have been improved.

Chinese Journal of School Health 2025;46(3):438-442
Objective:
To construct a scientific and perfect evaluation index system of infectious disease prevention and control ability in colleges and universities, so as to provide reference tools for colleges and universities to effectively respond to infectious disease.
Methods:
The initial framework of the evaluation index system of infectious disease prevention and control ability in colleges and universities was constructed by using literature analysis method. Experts familiar with infectious disease prevention and control or school health work were selected to conduct two rounds( n =16,18) of Delphi expert consultation for determining the evaluation index system. Analytical hierarchy process was used to calculate the index weights and combined weights. About 198 prevention and control personnel were conveniently selected from 3 universities in Inner Mongolia Autonomous Region to comprehensively evaluate the evaluation indicators by using fuzzy comprehensive evaluation method.
Results:
After two rounds of Delphi consultation questionnaire, the effective recovery rates were 80.0% and 90.0%, the expert authority levels were 0.89 and 0.86, the expert harmony coefficients for Kendall W were 0.166 and 0.310, and the variation coefficient of each index was <0.25. Finally, the evaluation index system of infectious disease prevention and control ability of colleges and universities included 4 first level indicators, 14 second level indicators and 75 third level indicators. The weights of prevention and monitoring and early warning, organizational system guarantee, emergency management, rehabilitation and summary were 0.176, 0.476, 0.268 and 0.080, respectively. The top 3 weights of the secondary indexes were 0.623 for infectious disease surveillance and early warning, 0.595 for loss assessment and 0.370 for emergency response. The score of fuzzy comprehensive evaluation of the index system of infectious disease prevention and control ability in colleges and universities was 79.148, suggesting a high level.

Purpose:
The aim of this study was to investigate the feasibility of an intelligent handheld ultrasound (US) device for assisting non-expert general practitioners (GPs) in detecting carotid plaques (CPs) in community populations.
Methods:
This prospective parallel controlled trial recruited 111 consecutive community residents. All of them underwent examinations by non-expert GPs and specialist doctors using handheld US devices (setting A, setting B, and setting C). The results of setting C with specialist doctors were considered the gold standard. Carotid intima-media thickness (CIMT) and the features of CPs were measured and recorded. The diagnostic performance of GPs in distinguishing CPs was evaluated using a receiver operating characteristic curve. Inter-observer agreement was compared using the intragroup correlation coefficient (ICC). Questionnaires were completed to evaluate clinical benefits.
Results:
Among the 111 community residents, 80, 96, and 112 CPs were detected in settings A, B, and C, respectively. Setting B exhibited better diagnostic performance than setting A for detecting CPs (area under the curve, 0.856 vs. 0.749; P<0.01). Setting B had better consistency with setting C than setting A in CIMT measurement and the assessment of CPs (ICC, 0.731 to 0.923). Moreover, measurements in setting B required less time than the other two settings (44.59 seconds vs. 108.87 seconds vs. 126.13 seconds, both P<0.01).
Conclusion
Using an intelligent handheld US device, GPs can perform CP screening and achieve a diagnostic capability comparable to that of specialist doctors.

Pyroptosis is the programmed death of cells accompanied by an inflammatory response and is widely involved in the development of a variety of diseases, such as infectious diseases, cardiovascular diseases, and neurodegeneration. It has been shown that cellular scorching is involved in the pathogenesis of pulmonary arterial hypertension ( PAH) in cardiovascular diseases. Patients with PAH have perivascular inflammatory infiltrates in lungs, pulmonary vasculopathy exists in an extremely inflam-matory microenvironment, and pro-inflammatory factors in cellular scorching drive pulmonary vascular remodelling in PAH patients. This article reviews the role of cellular scorch in the pathogenesis of PAH and the related research on drugs for the treatment of PAH, with the aim of providing new ideas for clinical treatment of PAH.

Objective:To summarize the experience and effect of extracorporeal cardiopulmonary resuscitation (ECPR) on the treatment of sudden cardiac death (SCD).Methods:The data of 120 adults with SCD-ECPR in emergency department of the first affiliated hospital of Nanjing Medical University from April 2015 to April 2023 were retrospectively analyzed. The patients were grouped by Survival/death at 90 days, OHCA/IHCA (out-of-hospital/in-hospital cardiac arrest), with/without acute myocardial infarction (AMI) and divided according to 60 min of the time from cardiac arrest to extracorporeal membrane oxygenation (ECMO) initiation (CA-Pump On time). Age, sex, Charlson comorbidity index, IHCA/OHCA, initial rhythm, no-flow time, CA-Pump On time, ECMO evacuation success rate, 90-day survival rate, ECMO treatment time were analyzed.Results:①Total of 114 adult patients with SCD-ECPR were enrolled, and 45 (39.5%) patients survived at 90 days, of whom 40 (88.9%) patients had good neurological outcomes.②Age and no-flow time were significantly lower in the 90-day survival group than that in death group, and the proportion of IHCA and shockable initial rhythm was higher. ③The no flow time in IHCA group was significantly lower than that in OHCA group, and the 90-day survival rate was higher. ④OHCA and regional interhospital transport prolonged CA-Pump On time and reduced the 90-day survival rate. ⑤The AMI group was older with a higher Charlson comorbidity index, and the 90-day survival rate was significantly lower than that in non-AMI group.Conclusions:ECPR improves the prognosis of patients with SCD, there are high benefits in patients with long healthy life expectancy, IHCA, shockable initial rhythm, and short no flow time. The smooth life-saving chain of SCD-ECPR improves survival rate, by screening high benefit candidates in patients with OHCA, delayed initiation of ECPR or requiring interhospital transport, despite CA-Pump On time > 60 min, there is still survival potential.
