Objective To assess the risk of human Spirometra mansoni infections and investigate the knowledge, attitude and practice (KAP) towards sparganosis mansoni among residents in Henan Province, so as to provide insights into formulation of the sparganosis mansoni control measures. Methods Qinling Village in Fugou County of Zhoukou City, Bali Village in Yancheng District of Luohe City, Duzhai Village in Puyang County of Puyang City and Doushan Village in Luoshan County of Xinyang City were sampled as survey sites in Henan Province from July to August 2023, and more than 40 frogs were sampled from ponds or streams in each survey site for detection of Sparganum mansoni infections. At least 150 residents were sampled using a cluster sampling method from each survey site, and the sero-prevalence of anti-S. mansoni IgG antibody was estimated. In addition, a questionnaire survey was conducted on the KAP towards sparganosis mansoni among participants, and the proportion of eligible KAP, rate of correct KAP and KAP scores were calculated. Results A total 229 frogs were collected from 4 survey sites in 2023, and the overall prevalence of S. mansoni infection was 4.37% (10/229) in frogs, with 7.75% (10/129) prevalence in wild frogs and 0 in farm-bred frogs. A questionnaire survey was performed among 649 residents sampled from 4 survey sites, and 649 serum samples were collected. The seroprevalence of anti-S.mansoni IgG antibody was 0.15% (1/649) and the overall proportion of eligible KAP was 23.73% (154/649) among participants. There were age- (χ² = 30.905, P = 0.000), educational level- (χ² = 41.011, P = 0.000), and occupation-specific proportions of eligible KAP among participants (χ² = 10.721, P = 0.005), and the proportion of eligible KAP decreased with age (χ² _trend = 22.717, P = 0.000) and increased with education levels (χ² _trend = 40.025, P = 0.000). The rates of correct KAP towards sparganosis mansoni were 40.81% (2 119/5 192), 96.66% (1 882/1 947) and 63.81% (3 727/5 841) (χ² = 1 913.731, P = 0.000) among residents, respectively. The rates of correct KAP towards sparganosis mansoni varied significantly among survey sites (χ² = 136.872, 42.347 and 255.157; all P values= 0.000, with the highest rate of correct knowledge (51.94%, 748/1 440) and practices (75.86%, 1 229/1 620) in Yancheng District of Luohe City and the highest rate of correct attitudes in Puyang County of Puyang City (99.11%, 446/450) (all P values< 0.05). Conclusions There is still a high transmission risk of sparganosis mansoni in Henan Province, and the KAP towards sparganosis mansoni is required to be improved among residents.

ObjectiveTo explore the evolution of medication patterns and syndrome-herb associations of traditional Chinese medicine （TCM） in treating inflammatory bowel disease （IBD）， providing a theoretical foundation for precise syndrome differentiation and treatment in clinical practice. MethodsMedical case literature on TCM treatment of IBD from 1960 to 2024 was retrieved to establish a database. Frequency statistics， cluster analysis， change point detection， and association rule mining were employed to comprehensively analyze the syndrome distribution， therapeutic methods， medication patterns， and their temporal variations. ResultsA total of 685 medical cases were included. Common syndromes were dampness-heat （66.42%） and spleen deficiency （56.20%）. Primary therapeutic methods included heat clearing （63.65%）， spleen invigorating （47.45%）， and dampness draining （36.79%）. High-frequency herbs included Coptidis Rhizoma （354）， Paeoniae Radix Alba （303）， Aucklandiae Radix （292）， Codonopsis Radix （253）， and Glycyrrhizae Radix et Rhizoma （244）. Initial prescription clustering revealed three core therapeutic method combinations： heat clearing and detoxifying （represented by Baitouweng Tang）， spleen invigorating and Qi reinforcing （represented by Shenling Baizhusan）， and cold-heat regulation （represented by Wumeiwan combined with Shaoyao tang）. Temporal analysis identified 2008 as a key transition point in TCM treatment of IBD， with significantly increased usage frequency of heat-clearing and dampness-drying herbs such as Fraxini Cortex， Phellodendri Chinensis Cortex， Sophorae Flavescentis Radix， and Scutellariae Radix as well as hemostatic herbs such as carbonized Sanguisorbae Radix， Bletillae Rhizoma， Agrimoniae Herba， and Notoginseng Radix et Rhizoma. Follow-up efficacy analysis showed median improvement rates of 64.0% at the first follow-up， 76.0% at the second follow-up， and 78.7% at the third follow-up. Syndrome-drug association analysis revealed specific herb pairs with significant therapeutic advantages， including Notoginseng Radix et Rhizoma + Coicis Semen， Sanguisorbae Radix + Coptidis Rhizoma， and Codonopsis Radix + Aconii Lateralis Radix Praeparaia. ConclusionTCM medication patterns for treating IBD demonstrate distinct temporal evolution characteristics， with significantly increased usage frequency of herbs such as Fraxini Cortex， Notoginseng Radix et Rhizoma， and Agrimoniae Herba. Significant therapeutic method-herb associations and syndrome-herb association patterns exist， with the formation of specific herb pairs， providing evidence-based support for precise syndrome differentiation and treatment of IBD.

Objective To systematically evaluate the impact of pulmonary hypertension (PH) on the prognosis of patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR). Methods A computerized search was conducted in CNKI, Wanfang Data, VIP, CBM, PubMed, The Cochrane Library, EMbase, and Web of Science databases from inception to June 2023 for cohort studies on the prognostic impact of PH in severe AS patients undergoing TAVR. Two researchers independently screened the literature, extracted data, and assessed the quality of included studies. Stata 17.0 software was used for meta-analysis. Results A total of 16 cohort studies were included, all with Newcastle-Ottawa Scale scores≥7. Meta-analysis results showed that, compared with AS patients without PH, those with PH had significantly higher 1-year all-cause mortality after TAVR [OR=2.10, 95%CI (1.60, 2.75), P<0.01], 30-day all-cause mortality [OR=2.09, 95%CI (1.54, 2.83), P<0.01], and cardiovascular mortality [OR=1.49, 95%CI (1.18, 1.90), P<0.01]. The differences between the two groups in major bleeding events, stroke, myocardial infarction, pacemaker implantation, and postoperative renal failure were not statistically significant. For outcome indicators with significant heterogeneity, subgroup analyses were performed based on PH measurement methods, diagnostic criteria, and different types of PH. The results showed that most subgroup combined results were consistent with the overall findings and that heterogeneity was significantly reduced. Conclusion PH significantly increases the 30-day all-cause mortality, 1-year all-cause mortality, and cardiovascular mortality in patients with severe AS undergoing TAVR.

Objective:To investigate the causal relationship between trimethylamine N-oxide (TMAO) and its precursors (betaine, carnitine, and choline) and pancreatic diseases based on the Mendelian randomization (MR) method.Methods:Genome-wide association study data of TMAO, betaine, carnitine, choline, acute pancreatitis (AP), chronic pancreatitis (CP), pancreatic cancer (PC), and circulating immune cell characteristics (white blood cell, lymphocyte, monocyte, neutrophil, eosinophil and basophil) were collected. According to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE)-MR reporting guidelines, the available genetic variants [single nucleotide polymorphism (SNP)] were strictly screened. The causal relationship between exposure (TMAO and its precursors) and outcomes (pancreatic diseases and circulating immune cell characteristics) was evaluated using inverse variance weighting (IVW), MR-Egger regression and weighted median. The reliability of the results was evaluated by sensitivity analysis based on MR-Egger regression, MR-PRESSO, Cochrane's Q test and leave-one-out method. Results:A total of 36 SNP associated with TMAO and its precursors were included. Five of these were associated with TMAO, 13 with betaine, 12 with carnitine, and 6 with choline. ① MR analysis showed that TMAO may increase the risk of AP [odds ratio ( OR) = 1.100, 95% confidence interval (95% CI) was 1.008-1.200, P = 0.032], and choline may reduce the risk of alcoholic acute pancreatitis (AAP; OR = 0.743, 95% CI was 0.585-0.944, P = 0.015). The analysis results of MR-Egger regression and weighted median were consistent with the IVW results. There is no evidence to support a causal relationship between TMAO and its precursors and the risk of CP and PC. Sensitivity analysis indicated that SNP analyzed by MR showed no heterogeneity and low pleiotropy. The leave-one-out method analysis determined that after excluding any SNP, the effect intervals of the remaining SNP on the results were similar to the overall effect intervals, which suggested the robustness of MR results. ② There was a positive causal relationship between plasma TMAO level and circulating monocyte count ( OR = 1.017, 95% CI was 1.000*-1.034, P = 0.048, * represented that the data was obtained by correcting to 3 decimal places from 1.000 1). The causal effect obtained by MR-Egger regression and weighted median analysis was consistent with the results of IVW. Sensitivity analysis illustrated SNP analyzed by MR showed no heterogeneity and pleiotropy. The leave-one-out method analysis determined that after excluding any SNP, the effect intervals of the remaining SNP on the results were similar to the overall effect intervals, which suggested the robustness of MR results. Conclusion:TMAO and choline may change the risk of AP, and TMAO may contribute to the increase of circulating monocyte count in AP.

Objective:To explore the influence of points system management on the career development of medical staff in health management discipline.Methods:Using a cross-sectional study design, medical staff in the health management discipline of tertiary hospitals in China were selected as the research objects from February 1 to March 1, 2024 through questionnaire star convenience sampling and snowball sampling, and their general information, performance appraisal satisfaction, professional identity, burnout, professional benefit, professional career management and other information were collected, and the correlation and influencing factors among them were explored. A total of 423 questionnaires were distributed, and 402 (95.0%) valid questionnaires were collected.Results:A total of 207 (51.5%) medical staff had job burnout, and 257 (63.9%) of them had medium or below level of professional identity. There were positive correlations among performance appraisal satisfaction, professional identity, career benefit and professional career management. There was a negative correlation between burnout and performance appraisal satisfaction ( r=-0.439), professional identity ( r=-0.356), career benefit ( r=-0.584), and professional career management ( r=-0.185) (all P<0.05). Higher age, working time, monthly income level, title level, position level, understanding of performance appraisal system, satisfaction with feedback results and application satisfaction were the protective factors of burnout, and under the points-based system, the scores of performance appraisal satisfaction, professional identity, career benefit, and professional career management were higher, and the differences were statistically significant (all P<0.05). A total of 310 medical staff (77.1%) believed that performance appraisal had a motivating effect on them. Conclusion:The performance appraisal of the point system has a good motivating effect on the medical staff of the health management discipline, and is closely related to professional identity, burnout, professional benefit, and professional career planning.

Objective To investigate the role of nuclear factor-κB(NF-κB)/NOD-like receptors family pyrin domain containing 3(NLRP3)pathway in limb ischemia-reperfusion injury(IRI)pretreated with ulinastatin(UTI).Methods Twenty-one SD rats were randomly divided into Sham group,IRI group,UTI group.In UTI group,ulinastatin was injected after anesthesia.After 10 minutes,the animal model was established by claming the femoral artery and ligaturing collateral circulation.After 3h of ischemia,the clamp and tourniquet were removed and the rats underwent 2h of reperfusion.In the other groups,the homologous saline was also injected in the same time.Plasma concentrations of lactate dehydrogenase(LDH)and creatine kinase(CK),interleukin(IL)-6,IL-18,tumor necrosis factor-α(TNF-α)were measured.The gastrocnemius muscle was harvested and immediately stored at-80℃.NF-κB and NLRP3 were detected by Western blot and PCR.The other section muscle was stored in triformol for HE staining.The wet/dry was also immediately detecting.Results The level of wet/dry,LDH,CK,IL-6,IL-18,TNF-α,NF-κB,NLRP3 IRI were higher than those in Sham group(P＜0.05).The level of wet/dry,LDH,CK,IL-6,IL-18,TNF-α,NF-κB,NLRP3 IRI were significantly lower than those in IRI group(P＜0.05).Conclusion Ulinastatin can reduce the cellular inflammatory response through the NF-κB/NLRP3 pathway,thereby achieving a protective effect on limb IRI in rats.

Objective To explore the application of Chinese Drug-Related Problems Classification System in the pharmaceutical care of inpatients in neurology department.Methods A total of 222 inpatients admitted to the Department of Neurology of Affiliated Jinhua Hospital,Zhejiang University School of Medicine from March to June 2022 were selected as the study subjects,and the work records of clinical pharmacists were retrospectively analyzed.The drug-related problems(DRP)were sorted and analyzed according to the Chinese Drug-Related Problems Classification System.Binomial Logistic regression model was used to analyse the influencing factors of DRP.Results Among the 222 patients,76(34.23%)had DRP and a total of 104 DRP were found.The main problem type of DRP was treatment safety(39.42%).The involving objects of DRP were all doctors.In the severity assessment,the most involved level was"DRP reached the patient,but the patient was not harmed"(81.73%).The main reason for DRP was"choice of drugs"(67.31%),followed by"usage and dosage"(26.92%).A total of 62(59.62%)DRP intervention schemes were accepted,and the overall acceptance rate of intervention schemes was 87.32%.In the end,61(58.65%)DRPs were resolved.The drug class with the largest number of DRP cases was antiplatelet drugs.Binomial Logistic regression analysis showed that the number of drug varieties[OR=1.097,95%CI(1.030,1.167)]was the influencing factor for the occurrence of DRP in neurology inpatients(P<0.05).Conclusion DRP is common in inpatients of neurology department.Chinese Drug-Related Problems Classification System is helpful for clinical pharmacists to review and sort pharmaceutical care data,summarize common problems and solving experience,and improve the effect of pharmaceutical care.

Objective:To treat the Crohn's disease(CD)patients with ustekinumab(UST),to eva-luate their clinical and endoscopic remission,and to evaluate their transmural response(TR)and trans-mural healing(TH)condition using intestinal ultrasonography(IUS).Methods:Retrospective analysis was made on patients diagnosed with CD in Peking University People's Hospital from January 2020 to Au-gust 2022,who were treated with UST for remission induction and maintenance therapy.All the patients were evaluated on both week 8 and week 16/20 after treatment,including clinical,biochemical indica-tors,colonoscopy and IUS examination.Results:A total of 13 patients were enrolled in this study,inclu-ding 11 males and 2 females.The minimum age was 23 years,the maximum age was 73 years and the mean age was 36.92 years.All the patients were in the active stage of disease before treatment,and the average Best Crohn's disease activity index(Best CDAI)score was 270.12±105.55.In week 8,the Best CDAI score of the patients decreased from 270.12±105.55 to 133.16±48.66(t=4.977,P＜0.001).Eight patients achieved clinical remission while 5 patients remained in the active stage.Nine patients underwent colonoscopy evaluation.The average simple endoscopic score for Crohn's disease(SES-CD)score decreased from 10.71±7.14 before treatment to 6.00±7.81(t=2.483,P=0.048)in week 16/20.Four patients achieved endoscopic remission while 5 patients did not.In week 8,5 pa-tients achieved TR,2 patients achieved TH,the other 6 patients did not get TR or TH.In week 16/20,6 patients achieved TR,3 patients achieved TH while the other 4 patients did not get TR or TH.There was no significant statistical difference in the TR effect of UST between small intestine and colon lesions(Fisher test,P＞0.999).The rate of UST transmural response in the patients who had had previous bio-logical agent therapy was lower than those with no previous biological agent therapy,but there was no sig-nificant statistical difference(Fisher test,P=0.491).Conclusion:After treatment of UST,the clinical and endoscopic conditions of the CD patients had been improved,and some patients could achieve clini-cal remission and endoscopic remission.UST had good TR and TH effects on CD.TR might appear in week 8,and the TR effect increased in week 16/20.There was no significant statistical difference in the TR effect between small intestine and colon lesions.TR effect of UST was better in the patients who had no previous biological agent therapy than those who had had other biological agents,but the result had no significant statistical difference.

Objective:To investigate the necessity of adaptive re-planning during radiotherapy for nasopharyngeal carcinoma (NPC) and its impact on dose improvement.Methods:Clinical data of 89 NPC patients admitted to Sun Yat-sen University Cancer Center from July 2014 to December 2017 were retrospectively analyzed. All patients received 25+7 rounds of adaptive re-planning during radiotherapy. Plan-A was defined as the initial CT scan-based 25-fraction radiotherapy plan, while plan-B was defined as the re-planned 7-fraction radiotherapy plan based on a subsequent CT scan. The changes in the target and parotid gland volumes were compared between plan-A and plan-B. Plan-I was a one-time simulation of plan-A extended to 32 fraction radiotherapy plan, and plan-II was generated through registration and fusion of the plan-A and plan-B for adaptive re-planning. The differences in dose metrics, homogeneity index (HI), conformity index (CI), and dose to organs at risk (OAR) were compared between plan-I and plan-II. Statistical analysis was performed by using paired t-test. Results:Compared with plan-A, the gross tumor volume of massive bleeding lesions (GTV nx) and parotid gland volume of plan-B were decreased by 13.14% and 11.12%, respectively (both P<0.001). While planning clinical target volume of metastatic lymph nodes (PCTV nd) of plan-B was increased by 7.75%( P<0.001). There were significant changes in the lymph nodes of plan-A and plan-B. The D mean, D 5%, D 95% of massive bleeding lesions planning target volume (PTV nx) and D 5% of high risk planning target volume (PTV1) in plan-II were all significantly higher than those in plan-I (all P<0.05). The CI of PTV nx and PTV1 in plan-II was closer to 1 than that in plan-I. In all assessed OAR, the D mean, D 50%, and D max of plan-II were significantly lower than those of plan-I (all P<0.05). Conclusions:During radiotherapy, NPC patients may experience varying degrees of primary tumor shrinkage, parotid gland atrophy, and lymph node changes. It is necessary to deliver re-planning and significantly improve the dose of target areas and OAR.

Objective:To quantify the associations between periconceptional maternal homocysteine (HCY) and offspring′s birth weight and risk of small for gestational age (SGA) infant.Methods:The 19 984 mother-child pairs in this prospective cohort study were recruited from the Shanghai preconception cohort; the infants were delivered from 1 st September 2016 to 11 th November 2022. A standardized questionnaire was used to collect the mothers′ demographic information, medical history, dietary supplement use, and maternal complications during pregnancy, and their serum samples were collected. Serum HCY, folate, and vitamin B 12 were measured using chemiluminescent microparticle immunoassay based on serum sample drawn at enrollment. Birth weight data were obtained from medical records. Multiple imputation methods were applied to handle missing data in key variables. Multivariable linear regression and Poisson regression models were used to analyze the relationship between maternal HCY concentration during the periconceptional period and the birth weight and SGA risk of the offspring. Results:A total of 9 452 pairs were enrolled preconceptionally and the remaining 10 532 pairs were enrolled in early pregnancy. The proportion of mothers whose pregnancy age was greater than 35 years was 9.2% (1 832/19 984), the proportion of primiparous women was 76.5% (15 283/19 984), the proportion of pre-pregnancy overweight and obesity was 14.0% (2 804/19 984), the proportion of using folic acid supplements before pregnancy was 21.4% (4 272/19 984), and the proportion of those who supplemented with folic acid during early pregnancy was 85.2% (8 976/10 532); gestational diabetes mellitus was in 6.2% (1 245/19 984), gestational hypertensive syndrome in 3.6% (711/19 984). The birth weight of the offspring was (3 297±468) g, and there were 1 962 SGA children (9.8%). The HCY concentration in the overall population in appropriate for gestational age during the periconceptional period was (7.9±3.2) μmol/L, with (8.3±3.7) μmol/L in the preconception subgroup and (7.3±2.4) μmol/L in the early pregnancy subgroup. After adjustment for the covariates of perinatal demographic information, adverse pregnancy outcomes, serum folate and vitamin B 12, increased maternal periconceptional HCY was significantly associated with lower offspring birth weight ( β=-2.30, 95% CI -4.43--0.16, P=0.035). Only the early pregnancy subgroup was significantly associated with lower offspring birth weight ( β=-7.39, 95% CI-11.50--3.21, P<0.001). No association was found between peripregnancy HCY and offspring SGA risk. However, elevated HCY in early pregnancy was associated with an increased risk of SGA in the offspring ( RR=1.05, 95% CI 1.01-1.08, P=0.002). Periconceptional vitamin B 12 was a mediator of the association between HCY and offspring birth weight, accounting for 16.5%, 41.2% and 5.4% of its total effect in the overall periconceptional population, the pre-pregnancy subgroup and the early pregnancy subgroup, respectively. Conclusions:Maternal periconceptional HCY level is associated with lower birth weight in offspring, but not with the risk of SGA. Elevated maternal HCY in early pregnancy subgroup may be associated with increased risk of SGA in offspring.
