ObjectiveTo identify the active constituents of Kaixuan Jiedu core prescription （KXJD） and investigate its effective components and therapeutic targets in the treatment of common psoriasis. MethodsUltra-performance liquid chromatography-high resolution mass spectrometry （UPLC-Q-TOF MS） was used to identify and analyze the chemical components of KXJD and its blood-entering chemical components. The chemical components of the single decoction were further identified to clarify the source of the chemical components in KXJD. Then， all identified blood-entering compounds were screened for effective active ingredients through the Swiss ADME database. The active ingredient targets of KXJD were searched on the Swiss Target Prediction platform. The targets of common psoriasis were searched in OMIM， GEO， GeneCards， and DISGNET databases to obtain drug-disease intersection targets. The protein-protein interaction network of intersection targets was constructed using STRING， and then the core blood-entering component-intersection target network of KXJD was constructed. The core target proteins in the network were selected for molecular docking with the core components of KXJD. Small molecules and proteins were pretreated， and appropriate docking sites were selected. AutoDock Vina software was used for continuous local search and repeated iterations to find molecular docking conformations. PyMOL software and LigPlot+ software were used for analysis and visualization. Subsequently， the verification was carried out through animal experiments. SPF-grade male C57 mice were randomly divided into a blank group， a model group， a positive drug methotrexate group， and a KXJD group. In the model group， the methotrexate group， and the KXJD group， imiquimod was applied to the backs of the mice for modeling. The blank group and the model group were administered normal saline by gavage， while the methotrexate group and the KXJD group were respectively administered 1 mg·kg^-1 suspension and 30.42 g·kg^-1 decoction of traditional Chinese medicine by gavage. Five days after administration， the mice were sacrificed， and samples were collected. Hematoxylin-eosin （HE） staining was used to observe the skin tissue samples of mice， and the effect of KXJD on the pathological manifestations of psoriasis mice was analyzed. The expression areas of tumor necrosis factor-α （TNF-α）， cyclooxygenase 2 （PTGS2）， interleukin （IL）-1β， and IL-6 in the skin tissue of mice were detected by immunohistochemistry （IHC）. The mRNA expressions of TNF-α， IL-1β， IL-6， and PTGS2 in the skin tissue of mice were detected by real-time fluorescent quantitative polymerase chain reaction （Real-time PCR）. ResultsIn this study， 208 compounds in KXJD were identified by UPLC-Q-TOF MS， and 44 compounds were detected in serum， including 28 prototype components and 16 metabolites. 12 blood-entering active components were screened， and 1 153 active component targets and 1 076 psoriasis-related targets were identified. Eighty-five targets in the intersection set were drug-disease common targets. PPI network analysis showed that TNF-α， IL-1β， IL-6， PTGS2， and ALB were the key target proteins. The results of molecular docking showed that the binding ability of （+）-hexylphenylglycolic acid to key target proteins such as PTGS2 was stable， and PTGS2 showed high stability with a variety of core compounds. Compared with those in the blank group， the stratum corneum and epidermis in the model group mice were significantly thickened， and the pathological Baker score of the mice's skin in the model group was significantly higher than that of the blank group （P<0.01）. The expression areas of PTGS2， TNF-α， IL-1β， and IL-6 proteins in the skin tissue of the model group mice were significantly increased （P<0.01）， and the expression levels of PTGS2， TNF-α， IL-1β， and IL-6 mRNA in the skin tissue of the model group mice were significantly elevated （P<0.01）. Compared with the model group， the pathological Baker scores of the methotrexate group and the KXJD group were both decreased （P<0.01）， and the expression areas in the skin tissue of the methotrexate group and the KXJD group were significantly reduced （P<0.05， P<0.01）. The expression levels of PTGS2， TNF-α， IL-1β， and IL-6 mRNA in the skin tissue of the methotrexate group and the KXJD group were significantly decreased （P<0.01）. ConclusionKXJD can effectively improve the skin lesions of psoriasis model mice and reduce the expression of TNF-α， IL-1β， IL-6， and PTGS2 in the skin tissue of psoriasis model mice. PTGS2 has a stable binding ability with a variety of compounds in the decoction， which may be a key target for the treatment of psoriasis. The compound （+）-hexylphenylglycolic acid may play a key role.

Toxoplasma gondii is an intracellular protozoan pathogen with a global distribution,and dogs are considered a potential risk factor for human toxoplasmosis.This study was aimed at systematically analyzing the epidemiological characteris-tics of canine T.gondii infection in China from 1987 to 2023,to provide a scientific basis for the prevention and control of T.gondii in the country.Epidemiological data on canine T.gondii infections in China from 1987 to 2023 were retrieved from PubMed,China National Knowledge Infrastructure(CNKI),Wanfang Database,and Baidu Scholar.A database was established with Excel,and the data were visualized with ArcGIS 10.2 software.Statistical analysis was performed in SPSS 26.0 software,and group differences were analyzed with the X2 test.A P-value of＜0.05 was considered statistically significant.From 1987 to 2023,the overall seroprevalence of T.gondii antibodies in dogs in China remained stable,and the overall sero-prevalence rate was 13.97％.Yunnan Province had the highest seroprevalence,at 27.65％,whereas Shaanxi Province had the lowest seroprevalence,at 0.56％.Significant differences were observed among provinces(P＜0.05).Epidemiological data on canine T.gondii infections were not available for some regions.The seroprevalence in southwestern China was significantly higher than that in other regions(P＜0.05).A comparison of the seroprevalence between 1987-2004 and 2005-2023 revealed significant differences(P＜0.05).Canine T.gondii infection is widespread in China and shows a stable epidemic cycle.Appro-priate prevention and control measures should be implemented,along with strengthened surveillance of T.gondii outbreaks.Public education on the prevention and control of toxoplasmosis should be enhanced to decrease transmission risk and safeguard public health.

Objective To retrospectively analyze the clinical risk factors and prognosis of perioperative myocardial injury(MINS)in non-cardiac surgery patients admitted to the intensive care unit(ICU).Methods A total of 478 postoperative patients admitted to the Department of Intensive Medicine,Minhang Hospital,Fudan University from Jan 2020 to Dec 2023 were selected.They were divided into MINS group(n=302)and normal group(n=176)based on whether myocardial injury occurred within 7 days after surgery.The differences in clinical characteristics between the two groups were compared,and risk factors for perioperative myocardial injury were identified.Risk factors for mortality in the MINS group were analyzed with 30-day mortality as the clinical endpoint.Results The prevalence of acute physiology and chronic health evaluation Ⅱ(Apache Ⅱ)score,coronary artery disease,and chronic kidney disease were all higher in the MINS group than those in the normal group,with statistically significant differences(P<0.05).The proportion of emergency surgeries,co-infection,and perioperative hypotension were significantly different between the MINS group and the normal group(P<0.05).Multivariate logistic regression analysis revealed that chronic kidney disease,emergency surgery,co-infection,and intraoperative and postoperative hypotension were risk factors for MINS occurrence.Prognostic analysis indicated that perioperative hypotension was a risk factor for 30-day mortality in MINS patients.Conclusion MINS is closely associated with patients'underlying conditions,timing of surgery,and perioperative hypotension status,and especially perioperative hypotension affects the final outcomes.

Objective To explore the short and long term efficacy of ultrasound therapy combined with muscle imbalance adjustment training in patients with adhesive capsulitis(AC) ofthe shoulder. Methods A total of 60 AC patients were divided into an observation group and a control group,both each consisting of 30 cases. The observation group underwentultrasound therapy along with muscle imbalance adjustment training,while the control group received acupuncture treatment,both for a duration of 20 days. The Visual Analogue Scale(VAS),goniom-eter for ROM,Manual Muscle Testing(MMT),Constant-Murley Shoulder Score,and modified Barthel index were used to access shoulder jointpain level,range of motion (ROM),peripheral muscle strength,shoulder joint func-tion,and daily living abilities,respectively. The Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD) were utilized to evaluate the levels of anxiety and depression.All the assessments were conducted and compared between the two groups before treatment,at the end of treatment,and at 6 and 12 months after treatment. Results Both groups showed varying degrees of improvement in ROM,MMT,VAS,Constant-Murley score,modified Barthel index,and emotional status compared to pre-treatment. The observation group demonstrated superior outcomes in posterior shoulder extension strength,VAS,Constant-Murley score,modified Barthel index,HAMA,and HAMD scores at the end of treatment (P<0.05). At 6 months post-treatment,the observation group showed better shoulder joint flexion,extension,abduction,and adduction ROM,as well as muscle strength in flexion,external rotation,and internal rotation,VAS,Constant-Murley score,modified Barthel index,HAMA,and HAMD scores. At 12 months after treatment,the observation group continued to show superior outcomes in all the aforementioned indexes (P<0.05). Conclusion The combination of ultrasound therapy and muscle imbalance adjustment training can effectively reduce shoulder joint pain,improve ROM,enhance muscle strength around the shoulder joint,improve shoulder joint function,alleviate anxiety and depression,and ultimately enhance the quality of life for patients with AC.

Exploratory factor analysis extracted six common factors, with a cumulative variance contribution rate of 69.415%. The final scale consisted of 26 items across five dimensions. The Cronbach α coefficient was 0.940, and the split-half reliability coefficient was 0.867. Conclusions:The Chinese version of the Oncofertility Barrier Scale exhibits good reliability and validity and can serve as an effective tool for evaluating factors hindering healthcare professionals in providing oncofertility care.

Objective To investigate the epidemiological status and molecular characteristics of diarrheagenic Escherichia coli(DEC)infection in Xiangshan County,providing a basis for its infection surveillance and outbreak control.Methods The real-time fluores-cence quantitative PCR(qRT-PCR)was used to detect virulence genes in isolated E.coli strains.The identified DEC strains were per-formed whole genome sequencing(WGS).The sequencing data were utilized for bacterial resistance gene analysis,multilocus sequence typing(MLST),and core genome multilocus sequence typing(cgMLST).Results A total of 29 DEC strains were isolated,with a detection rate of 9.8%.Enteroaggregative E.coli(EAEC)and enterotoxigenic E.coli(ETEC)were the main strains,accounting for 51.7%and 31.1%,respectively,while enteropathogenic E.coli(EPEC)had a relatively low proportion(17.2%).Drug resistance gene analysis showed that these strains were generally resistant to multiple antibiotics such as fluoroquinolones and carbapenems.MLST typing identified 19 sequence types(STs),including one novel ST type(STcpEC1).Among them,ST117,ST2178,ST31,and ST48 were dominant types.ETEC strains were mainly concentrated in the clonal complex CC-10,while the molecular typing of EAEC and EPEC strains was more dispersed.cgMLST analysis further confirmed the genetic characteristics of different DEC strains.Conclusion DEC infections in Xiangshan County are mainly caused by EAEC,ETEC,and EPEC.These strains have abundant resistance genes.Among them,the molecular typing of EAEC and EPEC is relatively dispersed,while ETEC is concentrated in the clonal complex CC-10.

Objective:To analyze the effects of centralized volume-based procurement policy for coronary stents on direct medical expenses related to cardiovascular disease within one year after first Percutaneous Coronary Intervention(PCI)among patients with Acute Coronary Syndrome(ACS),based on real-world data of Shanghai medical institutions.Methods:ACS patients who underwent their first PCI in Shanghai between March 2019 and April 2022 were selected,and their data of cardiovascular-related medical care and direct medical expenses in outpatient visits and readmissions within one year after first PCI were collected.The policy effects on direct medical expenses related to cardiovascular disease within 1 month,3 months,6 months and 1 year after first PCI were analyzed,using Wilcoxon rank sum tests and a multilevel generalized linear mixed model.Results:After the implementation of coronary stent policy,the average total direct medical expense(including outpatient visits and readmissions)related to cardiovascular disease within 1 month,3 months,6 months and 1 year after first PCI in ACS patients significantly decreased in Shanghai;and the multivariate generalized linear mixed model also indicated that the policy implementation reduced the direct medical expenses related to cardiovascular disease for these patients within one year after first PCI.Conclusions:The implementation of coronary stent policy in Shanghai reduced direct medical expenses related to cardiovascular disease within one year after first PCI in ACS patients,alleviating patients' financial burden.It is recommended that medical expenses after first PCI among patients with ACS should be further reduced and that long-term follow-up assessment on social impacts of coronary stent policies should be conducted.

As population aging intensifies,stroke incidence is rising yearly.Complicated with neurological impairment,this condition often leads to motor dysfunction,affecting walking stability and coordination and severely impacting the patient's daily life and mental state.In recent years,digital technology-assisted walking rehabilitation training has shown great potential in post-stroke rehabilitation.By integrating modern digital technolo-gies such as virtual reality,intelligent feedback systems,and remote rehabilitation,this approach not only provides personalized rehabilitation plans but also promotes the recovery of walking function through immersive training,real-time feedback,and remote monitoring.This article reviews the application status,effectiveness,and limita-tions of digital-technology-assisted walking rehabilitation for post-stroke hemiplegic patients.It aims to clarify the new direction of post-stroke walking training and explore more effective rehabilitation methods to help patients regain their walking ability.

Objective By establishing a model to screen out patients with potentially large positional deviations based on their abdominal circumference,personalized solutions can be taken to address setup errors in these patients and ensure treatment efficacy.Methods A total of 81 patients treated at Tianjin People's Hospital from May 2021 to June 2023 were selected as the study subjects.The correlations between setup errors in the lateral,longitudinal,and vertical directions and abdominal circumference were analyzed.Subsequently,linear regression was performed for the direction with a significant correlation to abdominal circumference to establish a linear regression model.Finally,the 81 patients were divided into a normal setup group and an abnormal setup group with 0.7 cm as the critical value.A receiver operating characteristic(ROC)curve was plotted,and the maximum Youden index was calculated to determine the optimal cutoff value for identifying patients prone to abnormal setup.Results The correlation analysis of abdominal circumference and setup errors in various directions showed that the correlation coefficient between abdominal circumference and longitudinal direction positioning error was 0.406 2,and the correlation was statistically significant and positively correlated.The correlation coefficients for abdominal circumference and the lateral as well as longitudinal directions were-0.117 5 and-0.067 47,respectively,with P values greater than 0.05,indicating no statistical significance.A linear regression model was established for abdominal circumference and longitudinal direction,and the results showed an R2of 0.165,with a regression coefficient B of 0.008(t=3.951,P<0.01),indicating that the model was well constructed.ROC curve analysis showed an area under the curve of 0.715,with a 95%confidence interval of 0.57-0.86 and a maximum Youden index of 0.478.The corresponding optimal cutoff value was determined to be at 87 cm,with sensitivity at 0.875 and specificity at 0.603.Conclusion The abdominal circumference is significant to diagnose whether the longitudinal setup error is abnormal.Patients with an abdominal circumference greater than 87 cm are more likely to experience abnormal positioning during radiotherapy,which is reflected in the longitudinal setup errors being the largest.It is recommended to provide individualized target area margins for patients with an abdominal circumference greater than 87 cm,or perform daily cone-beam computed tomography to correct setup errors,thereby ensuring target coverage and treatment efficacy.
