ObjectiveTo explore the effect of the medical-community linkage model on activities of daily living, psychological status and motor function of stroke patients in the community. MethodsA total of 60 stroke patients admitted to two community health service centers and their affiliated stations in Fengtai District, Beijing, from January, 2024 to August, 2025 were enrolled and randomly divided into control group (n = 30) and intervention group (n = 30). The control group received routine medicine, dietary care and rehabilitation management, while the intervention group underwent rehabilitation with the medical-community linkage model, for twelve weeks. They were assessed with modified Barthel Index (MBI), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD) and Fugl-Meyer Assessment (FMA) before and after intervention. ResultsAfter intervention, the MBI, HAMA, HAMD and FMA scores of patients improved in both groups (|t| > 5.599, P < 0.001), and improved more in the intervention group than in the control group (P < 0.05), except MBI. The HAMA and HAMD scores of family members decreased in both groups (|t| > 10.333, P < 0.001), and decreased more in the intervention group than in the control group (t > 5.681, P < 0.001). ConclusionThe medical-community linkage model can further improve the motor function of stroke patients in community, as well as the psychological status of both patients and their family members.

Objective To gain insights into the biological characteristics of different populations of Culex tritaeniorhynchus within and around the Yellow Sea wetland from the perspective of the occurrence of resistance, we investigated the levels of resistance to deltamethrin and kdr gene mutation in the wetland and its peripheral areas. Methods Specimens were collected from Cx. tritaeniorhynchus populations at two monitoring sites in the Rare Bird National Nature Reserve and Tiaozi Ni Wetland Scenic Area, and also from two populations in Yancheng City and the Liuhe District of Nanjing, and the resistance of these mosquitoes to deltamethrin was determined using the CDC biotest bottle method. For each concentration of deltamethrin assessed, a random subset of exposed specimens was selected for amplification of the kdr gene fragment, followed by Sanger sequencing to identify and analyze resistance-associated mutations. Results The LC50 levels of deltamethrin among mosquitoes from the four populations in Luhe, Yancheng, the Rare Bird National Nature Reserve and the Tiaozi Ni Wetland Scenic Area were 2.048 5, 7.798 2, 3.473 3, and 17.695 5 mg/mL, respectively, with corresponding concentrations of deltamethrin ranging from 0.005 to 5.000,0.050 to 50.000,0.050 to 25.000 and 0.050 to 50.000 mg/mL, respectively. Furthermore, the ranges of the KT50 values were 11.76-107.43, 67.05-216.30,29.77-107.43 and 28.40-329.51 min; the 1-h knockdown rates were 34.58%-99.15%, 9.52%-43.80%, 55.09%-73.01%, and 10.09%-68.07%; and the 24-h mortality rates were 12.15%-67.52%,9.52%-79.56%,13.17%-82.21%, and 11.01%-78.99%, respectively. With respect to kdr gene mutation, we assayed a total of 63,70,59, and 57 mosquitoes for the four populations, for which we detected L1014F mutation frequencies of 14.29%, 35.00%, 20.34%, and 31.58%, respectively, with a majority of these mutations being heterozygous for resistance. In addition, five adult mosquitoes were identified has having synonymous mutations at site 1011[i. e. , AAT(asparagine)mutation to AAC(asparagine)]. Conclusions Our findings revealed the clear resistance of Cx. tritaeniorhynchus to deltamethrin in the Yancheng region of the Yellow Sea wetland, and the resistance phenotype and kdr frequency of Cx. tritaeniorhynchus in the wetland environment were comparable to those of Cx. tritaeniorhynchus in the wetland environment, thereby indicating that the resistance of different populations of Cx. tritaeniorhynchus was homogeneous under the pressure of different insecticide selection within and around the wetland. However, the underlying mechanisms need to be further studied.

Inflammatory bowel disease(IBD)is a common di-gestive system disease with an increasing morbidity year by year.Its pathological mechanisms have not been fully clarified,and there are currently no ideal or effective curative methods.Phos-phodiesterase(PDE)can regulate intracellular cAMP/cGMP levels to mediate downstream signaling pathways,participating in various pathophysiological processes.In recent years,the po-tential efficacy of PDE inhibitors in the treatment of IBD has gradually attracted attention.This article reviews the pharmaco-logical effects and mechanisms of selective PDE subtype inhibi-tors in the prevention and treatment of IBD,providing references for further research of IBD therapeutic drugs.

Objective:To explore the application effect of different doses of dexmedetomidine combined with propofol in elderly patients undergoing radical thyroidectomy for thyroid cancer.Methods:This study was a prospective study,102 elderly patients undergoing radical thyroidectomy for thyroid cancer at Shayang County People's Hospital of Jingmen from April 2022 to April 2024 were selected,they were randomly divided into low-dose group and high-dose group used random number table method,with 51 patients in each group.Low-dose group received propofol(2.0 mg/kg)combined with dexmedetomidine(loading dose 0.3 μg/kg)for anesthesia induction,while high-dose group received propofol(1.0 mg/kg)combined with dexmedetomidine(loading dose 0.6 μg/kg)for anesthesia induction.The postoperative recovery indicators,pain level,cognitive function,hemodynamic indicators[mean arterial pressure(MAP)and heart rate(HR)],and adverse reactions between two groups were compared.Results:Compared with high-dose group,low-dose group had shorter awakening time,spontaneous breathing recovery time,tracheal extubation time,and lower incidence of adverse reactions(P＜0.05).Compared with high-dose group at 6 h,12 h,and 24 h after surgery,low-dose group had lower pain visual analog scale(VAS)scores and higher mini-mental state examination(MMSE)scores(P＜0.05).Compared with high-dose group at separation of thyroid gland(T2)to completion of surgery(T3),low-dose group had lower MAP and HR(P＜0.05).Conclusion:Loading dose 0.3 μg/kg dexmedetomidine combined with propofol has a good analgesic effect in elderly patients undergoing radical surgery for thyroid cancer,it can also maintain hemodynamic stability,reduce the impact on cognitive function,and lower the incidence of adverse reactions.

A mounting body of research suggests that circRNAs significantly contribute to the develop-ment of myocardial fibrosis.The microarray results of human circular RNA expression profile indicated that circHERC4_041 expression increased in the myocardium of patients with heart failure,RT-qPCR a-nalysis confirmed that the myocardial expression level of circHERC4_041 in individuals with heart failure were considerably elevated compared to that in healthy organ donors.Fluorescence in situ hybridization(FISH)confirmed that circHERC4_041 was abundant in the cytoplasm of human cardiomyocyte AC16.Overexpression of circHERC4_041 in mouse myocardial fibroblasts(mCFs)mediated by adenovirus in-hibited the expression of fibrosis-related proteins in mCFs.Experiments involving cell proliferation,wound healing,and Transwell assays demonstrated that overexpression of circHERC4_041 suppressed the growth and mobility of mCFs(P＜0.001).Sequence analysis results suggested that circHERC4_041 con-tains potential ribosome entry sequence(IRES)and open reading frame(ORF).Western blot confirmed that circHERC4_041 could translate the 516 amino acid HERC4-516aa protein,which was mainly located in the cytoplasm of the cell.Cell functional experiments confirmed that circHERC4_041 inhibited the fi-brotic phenotype of mCFs by specifically translating HERC4-516aa(P＜0.05).The specific interaction between HERC4-516aa and transglutaminase 2(TGM2)was confirmed by IP-MS screening and Co-IP i-dentification.Further results found that the degradation of TGM2 was promoted through proteasome path-way.The overexpression of TGM2 in mCFs facilitated by adenoviral vectors could counteract the suppres-sive effects of HERC4-516aa on the fibrotic phenotype of mCFs.Therefore,this study confirmed that the HERC4-516aa protein translated by circHERC4_041 can specifically bind to TGM2 to inhibit the fibrotic phenotype of myocardial fibroblasts.

Objective To analyze the epidemic trend and characteristics of notifiable infectious diseases in Xindu District of Chengdu,and to explore the changes of disease spectrum,so as to provide scientific basis for formulating prevention and control strategies.Methods The epidemic data of notifiable infectious diseases in Xindu District of Chengdu from 2008 to 2022 were collected and analyzed by descriptive epidemiological method.Results From 2008 to 2022,a total of 66 302 cases of 28 kinds of notifiable infectious diseases were reported in Xindu District of Chengdu,with an average annual reported incidence of 516.94/100 000.A total of 266 deaths were reported,with an average annual mortality rate of 2.07/100 000 and a case fatality rate of 0.40% .No Class A infectious diseases were reported,and Class B infectious diseases had no obvious seasonality.Class C infectious diseases had two incidence peaks from June to August and from October to December.The sex ratio of male to female was 1.41∶1,and the age of onset was mostly 0-4 years old.The reported cases were mainly scattered children,preschool children,students,farmers,housework and unemployed people.According to the main mode of transmission,the annual average reported incidence rate from high to low was intestinal infectious diseases,respiratory infectious diseases,blood and sexually transmitted infectious diseases,insect-borne and natural focal infectious diseases,and other infectious diseases.The mode of transmission gradually transitioned from intestinal infectious diseases to respiratory infectious diseases.From 2020 to 2022,except for COVID-19 and influenza cases,the reported incidence of infectious diseases in other transmission routes decreased.The reported diseases were mainly concentrated in tuberculosis,hepatitis B,syphilis,mumps,hand-foot-mouth disease,influenza and other infectious diarrhea,and the annual reported incidence order changed slightly.Conclusion From 2008 to 2022,the reported incidence of Class B infectious diseases in Xindu District of Chengdu showed a steady decline,while the reported incidence of Class C infectious diseases showed a fluctuating upward trend.The prevention and control measures of the new coronavirus epidemic are conducive to reducing the incidence of notifiable infectious diseases.It is necessary to focus on the prevention and control of high-risk infectious diseases such as hand-foot-mouth disease,influenza,other infectious diarrhea,tuberculosis,hepatitis B,and acquired immune deficiency syndrome,with highly reported mortality.Targeted health interventions should be carried out for key populations,key seasons,and key areas.At the same time,the monitoring of new and rare infectious diseases should be strengthened.

Objective:To assess the relationship between basophil levels and mortality in patients with intra-abdominal infection.Methods:Information on patients with intraperitoneal infection admitted to the intensive care unit were extracted from the MIMIC database.A time-dependent Cox regression model was used to adjust for confounders associated with 28-day mortality.Propensity score matching(PSM)was used to balance the baseline differences be-tween groups with different basophil levels,and a restricted cube chart(RCS)was used to show the relationship between basophil count and 28-day mortality in patients with intra-abdominal infection.Results:A total of 4403 patients with intra-abdominal infection were enrolled in the MIMIC database.Patients with high basophil levels have lower mortality than those with low basophil levels.There was an L-shaped curve between basophil level and 28-day mortality,with a cut-off value of 0.47×109/L.Cox regression analysis showed that basophil levels were an independent protective factor for mortal-ity in patients with intra-abdominal infection after adjusting for potential confounders(HR=0.586,95%CI:0.443-0.769).Protective factors for death at basophil levels remained after PSM adjusted for potential confounders(HR=0.628,95%CI:0.470-0.832).Conclusion:Basophil level is an independent protective factor for mortality in patients with intra-abdominal infection,and basophil levels should be dynamically monitored to better evaluate the prognosis of patients.

Strangles,caused by Streptococcus equi subsp.equi,remains one of the most prevalent and high-incidence infectious diseases in intensive donkey farms,posing a significant threat to the healthy development of the donkey industry.Vaccination serves as an effective measure for the pre-vention and control of the disease,however,there is currently no attenuated vaccine against this disease in China.To provide a candidate strain for the development of a live attenuated strangles vaccine,this study focused on a wild-type S.equi subsp.equi strain isolated from donkeys.Using homologous recombination gene knockout technology,the aroA gene(encoding 5-enolpyru-vylshikimate-3-phosphate synthase)and the sag A gene(encoding the precursor of streptolysin S toxin)were sequentially deleted to construct a double-gene-deletion strain(ΔsagA/aroA).The virulence and key biological characteristics of the mutant strain were systematically evaluated.TheΔsagA/aroA strain was successfully generated,exhibiting complete loss of hemolytic activity and maintaining stable genetic inheritance over 60 consecutive passages.Electron microscopy revealed that the mutant retained morphological characteristics compared to the wild-type strain,and its growth rate was significantly slower(P＜0.000 1).Virulence assessment using a challenge dose of 1× 105 CFU/0.2 mL(the minimum fully lethal dose of the wild-type strain)demonstrated markedly attenuated virulence in the mutant.Immunization trials with 1 ×104 CFU/0.2 mL of theΔsagA/aroA strain revealed a increase in ELISA antibody titers by day 7 post-vaccination,and higher levels at days 14 and 21.Notably,antibody levels in the experimental group were significant-ly higher than those in the control group(P＜0.000 1).These findings confirm that the double-gene-deletion strain S.equi subsp.equi ΔsagA/aroA exhibits reduced virulence while retaining im-munogenicity,which suggested it can be used as a promising candidate strain for further develop-ment of a live attenuated strangles vaccine.

Objective:To observe the application effect of hyperbaric oxygen combined with task oriented training in hemiplegic patients after cerebral infarction.Methods:106 hemiplegic patients after cerebral infarction admitted to Xinglin Hospital of Xiamen from March 2022 to June 2024 were prospectively selected and randomly divided into control group(received task oriented training,n=53)and observation group(received hyperbaric oxygen combined with task oriented training,n=53).Berg balance scale(BBS),clinical spasticity index(CSI),national institute of health stroke Scale(NIHSS),motor function[fugl-meyer motor function assessment scale(FMA),motor assessment scale(MAS)],walking ability[functional ambulation category(FAC),6-minute walking distance(6MWD)],quality of life and self-care ability[quality of life scale for stroke(SS-QOL),activity of daily living(ADL)]before intervention and 8 weeks after intervention were compared between the two groups.Result:Compared with control group 8 weeks after intervention,the observation group had higher BBS,FMA,MAS,FAC,SS-QOL,ADL scores,and 6MWD,while had lower NIHSS and CSI scores(P＜0.05).Conclusion:Hyperbaric oxygen combined with task oriented training in hemiplegic patients after cerebral infarction,can effectively improve patients' motor function,balance ability,and self-care ability,enhance their quality of life,and reduce neurological damage.
