Due to the prominent unhealthy lifestyle of residents,accelerated population aging,and urbanization processes in our country,the impact of cardiovascular disease(CVD)risk factors on public health is becoming increasingly significant.The prevalence of cardiovascular disease(CVD)in China is still on the rise.It is estimated that there are 330 million people with CVD,including 13 million cases of stroke,11.39 million cases of coronary heart disease,8.9 million cases of heart failure,5 million cases of pulmonary heart disease,4.87 million atrial fibrillation,2.5 million cases of rheumatic heart disease,2 million cases of congenital heart disease,45.3 million cases of peripheral arterial disease,and 245 million cases of hypertension.The economic burden of CVD on residents and society is increasingly heavy,making it a significant public health issue.The turning point for the prevention and control of CVD has not yet arrived,and it is urgent to strengthen government-led efforts in CVD prevention and control.

Although indigenous malaria has been eliminated in Wuhan since 2013,imported malaria remains a potential threat as an infectious source of local malaria transmission.The epidemiological and clinical characteristics of imported malaria are particularly important in areas where local malaria has been eliminated.This study was aimed at analyzing the epidemiological and clinical characteristics of imported malaria in Wuhan from 2012 to 2019,to provide a basis for further improving the preven-tion and control of imported malaria.Patients in Wuhan diagnosed with imported malaria from January 1,2012,to December 31,2019,were included in this study.A case-control study was con-ducted to analyze the features of patients with severe malaria.Uni-variate and multivariate logistic regression was used to identify risk factors for prolonged hospital length of stay(LOS).Among 229 imported malaria cases,212(92.6％)were in Chinese citizens,and most cases were in men(96.5％).The gender ratio is 28:1,and the age of cases is mainly concertrated between 18 and 50 years old(89.1％).More than 80％of patients were mi-grant workers,and most cases were infections from African countries(92.6％).Plasmodium falciparum(80.8％)was the dominant species.Fifty-three severe malaria cases were identified during the study period.Compared with uncomplicated cases,severe cases tended to occur in patients with no history of malaria(P=0.008),patients infected with Plasmodium falciparum(P=0.009),and patients who were initially misdiagnosed(P＜0.001).The median LOS was 6 days,and the species of infec-tion(Plasmodium falciparum),the use of antimalarial drugs(group B),antipyretic time(longer than 3 days),and the turn-around time of blood smear microscopy(longer than 3 days)were significantly associated with longer LOS(all P＜0.05).Al-though malaria has been eradicated in Wuhan for many years,imported cases continue to pose a threat.Efforts should be made to strengthen malaria knowledge education for outbound personnel.Additionally,medical institutions must enhance diagnosis and treatment capabilities for malaria,and adhere to standardized treatment processes,and the development of drug resistance and occurrence of severe malaria must be prevented.

Objective:To investigate the incidence and prothrombotic risk factors of postoperative venous thromboembolism(VTE) in Cushing′s disease and to further develop an assessment model to identify those at high risk of postoperative VTE events.Methods:A retrospective study was performed in 82 patients who were admitted to Huashan Hospital, Fudan University during January 2019 and January 2020 and diagnosed with Cushing′s disease. These patients underwent the evaluation about their clinical, hormonal, and coagulation parameters, as well as ultrasonography and pulmonary angio-CT when necessary. The least absolute shrinkage and selection operator(LASSO) regression analysis was used to screen independent risk factors, and a nomogram model for postsurgical VTE risk assessment in Cushing′s disease was initially established, and Bootstrap method was used for internal verification. Finally, the predictive model was evaluated for calibration and clinical applicability in the study cohort.Results:Nineteen patients(23.17%) developed VTE events, with 14 cases occurring after endoscopic transsphenoidal surgery. Compared to patients without VTE, those in the VTE group were older( P<0.001), had longer postoperative bed rest, higher rates of current infection, higher HbA 1C levels, and more severe glucose tolerance impairment(all P<0.05). Through LASSO regression analysis, two independent risk factors for postoperative VTE were identified: Age and current infection. Then a VTE risk assessment nomogram model was established to predict the patients at high risk of VTE. In the nomogram model for VTE risk assessment, the area under the receiver operating characteristic curve was 0.868(95% CI 0.787-0.949), with the calibration curve closely aligning with the ideal diagonal line and the clinical decision curve exceeding the two extreme curves. Conclusions:Advanced perioperative assessment needs to be taken to screen those with high VTE risks in patients diagnosed with Cushing′s disease. Additionally, during the perioperative period, patients with Cushing′s disease should undergo mandatory physical activity or prophylactic anticoagulant therapy.

Objective:To analyze the changes in the disease burden of prostate,testis,kidney and bladder cancers among uri-nary and reproductive system tumors in Chinese men from 1990 to 2019 with a prediction of the future trend.Methods:We re-trieved the data on the incidence,mortality and disease burden of prostate,testis,kidney and bladder cancers in Chinese men between 1990 and 2019 from the database of Global Burden of Disease Study 2019.Using the Joinpoint regression model,we analyzed the trend of changes in the disease burden,and predicted the prevalence of the tumors with the ARIMA model.Results:From 1990 to 2019,the standardized incidence and prevalence of prostate,testis,kidney and bladder cancers were on the rise in Chinese men,and those of testis cancer increased most significantly,by 326.79% and 1070.93% respectively.The disease burden of PCa was the highest,with standardized incidence,prevalence and mortality ratios of 17.34/100 000,117.65/100 000 and 7.79/100 000 respectively in 2019.The standardized mortality and disability-adjusted life years(DALY)of kidney cancer were increased by 103.59% and 103.17% respectively.The highest incidence,mortality and DALY of prostate,kidney and bladder cancers in 2019 were found in 90-94 years old males,the highest prevalence rates of prostate,kidney and bladder cancers in the 70-89-year-olds,and the highest prevalence of testis cancer in the25-49-year-olds.ARIMA model prediction showed that the standardized incidence rates of prostate,testis,kidney and bladder cancers in Chinese men kept rising from 2020 to 2029.Conclusion:The disease burden of prostate,tes-tis,kidney and bladder cancers in Chinese men is on the rise,and their standardized incidence rates will be even higher by 2029,with a significant increase in the disease burden in young men,which suggests the need of more attention to the prevention and treatment of genitourinary system tumors in young males.

Objective:To evaluate the application of modular teaching program in the clinical competence training for community general practitioners.Methods:This was a cross-sectional study. A 140 teaching hour-modular training program was designed by the authors on the basis of the previous training experience and conducted in clinical competence training for 20 general practitioners (study group) from all 10 community health service centers in Shanghai Huangpu district between September 2022 and April 2023; and 26 general practitioners who planned to participate in the next batch of training courses were enrolled as the control group. The clinical competence assessment was conducted in May 2023, including knowledge level tests and clinical skill assessment. By comparing the scores of clinical competence assessment and satisfaction survey between two groups, the training effectiveness was evaluated.Results:Among the 46 general practitioners, 33 (71.7%) were female, aged 27 to 47 (37±6), working in general practice for 2 to 25 (9.4±5.5) years, 31 (67.4%) had participated in standardized residency training for general practice and 31 (67.4%) were contracted family doctors. The total score of 46 general practitioners was 69.7±9.6, and 68.9±8.6 for knowledge level and 69.8±10.6 for clinical skills. The total scores and single scores of trained participants were all significantly higher than those of untrained(all P<0.05). The multiple linear regression model showed that after controlling for gender, age, educational background, professional title, years of working in general practice, participation in standardized residency training, and status as a contracted family doctor, the trained participants had significantly higher scores in history collection, pediatric reception, indwelling gastric tube and abdominal puncture (all P<0.05). There was no statistically significant difference in the scores in knowledge level test, nervous system physical examination, SOAP medical record writing, and tutorium between the trained and untrained groups (all P>0.05). Among 20 general practitioners who completed training, the overall satisfaction score of the training program was 4.3±0.7 points, including 4.3±0.6 for the training course, 4.3±0.7 for teachers, and 4.3±0.7 for the organization and arrangement; 85% of the participants considered the training to be very helpful or helpful for improving their competence, and 90% considered the training to be very helpful or helpful for their future work. Conclusion:Modular teaching program is helpful to improve the clinical competence of community general practitioners, especially in clinical skills.

Objective:To evaluate the efficacy and safety of hypomethylating agents (HMA) in patients with myelodysplastic syndromes (MDS) .Methods:A total of 409 MDS patients from 45 hospitals in Zhejiang province who received at least four consecutive cycles of HMA monotherapy as initial therapy were enrolled to evaluate the efficacy and safety of HMA. Mann-Whitney U or Chi-square tests were used to compare the differences in the clinical data. Logistic regression and Cox regression were used to analyze the factors affecting efficacy and survival. Kaplan-Meier was used for survival analysis. Results:Patients received HMA treatment for a median of 6 cycles (range, 4-25 cycles) . The complete remission (CR) rate was 33.98% and the overall response rate (ORR) was 77.02%. Multivariate analysis revealed that complex karyotype ( P=0.02, OR=0.39, 95% CI 0.18-0.84) was an independent favorable factor for CR rate. TP53 mutation ( P=0.02, OR=0.22, 95% CI 0.06-0.77) was a predictive factor for a higher ORR. The median OS for the HMA-treated patients was 25.67 (95% CI 21.14-30.19) months. HMA response ( P=0.036, HR=0.47, 95% CI 0.23-0.95) was an independent favorable prognostic factor, whereas complex karyotype ( P=0.024, HR=2.14, 95% CI 1.10-4.15) , leukemia transformation ( P<0.001, HR=2.839, 95% CI 1.64-4.92) , and TP53 mutation ( P=0.012, HR=2.19, 95% CI 1.19-4.07) were independent adverse prognostic factors. There was no significant difference in efficacy and survival between the reduced and standard doses of HMA. The CR rate and ORR of MDS patients treated with decitabine and azacitidine were not significantly different. The median OS of patients treated with decitabine was longer compared with that of patients treated with azacitidine (29.53 months vs 20.17 months, P=0.007) . The incidence of bone marrow suppression and pneumonia in the decitabine group was higher compared with that in the azacitidine group. Conclusion:Continuous and regular use of appropriate doses of hypomethylating agents may benefit MDS patients to the greatest extent if it is tolerated.

Objective To investigate the attributable risk(AR)of Acinetobacter baumannii(AB)infection in criti-cally ill patients.Methods A multicenter retrospective cohort study was conducted among adult patients in inten-sive care unit(ICU).Patients with AB isolated from sterile body fluid and confirmed with AB infection in each cen-ter were selected as the infected group.According to the matching criteria that patients should be from the same pe-riod,in the same ICU,as well as with similar APACHE Ⅱ score(±5 points)and primary diagnosis,patients who did not infect with AB were selected as the non-infected group in a 1:2 ratio.The AR was calculated.Results The in-hospital mortality of patients with AB infection in sterile body fluid was 33.3％,and that of non-infected group was 23.1％,with no statistically significant difference between the two groups(P=0.069).The AR was 10.2％(95％CI:-2.3％-22.8％).There is no statistically significant difference in mortality between non-infected pa-tients and infected patients from whose blood,cerebrospinal fluid and other specimen sources AB were isolated(P＞0.05).After infected with AB,critically ill patients with the major diagnosis of pulmonary infection had the high-est AR.There was no statistically significant difference in mortality between patients in the infected and non-infec-ted groups(P＞0.05),or between other diagnostic classifications.Conclusion The prognosis of AB infection in critically ill patients is highly overestimated,but active healthcare-associated infection control for AB in the ICU should still be carried out.

Objective To observe the efficacy and safety of Morinda officinalis oligosaccharides in the continuation treatment of mild and moderate depression.Methods An open,single-arm,multi-center design was adopted in our study.Adult patients with mild and moderate depression who had received acute treatment of Morinda officinalis oligosaccharides were enrolled and continue to receive Morinda officinalis oligosaccharides capsules for 24 weeks,the dose remained unchanged during continuation treatment.The remission rate,recurrence rate,recurrence time,and the change from baseline to endpoint of Hamilton Depression Scale(HAMD),Hamilton Anxiety Scale(HAMA),Clinical Global Impression-Severity(CGI-S)and Arizona Sexual Experience Scale(ASEX)were evaluated.The incidence of treatment-related adverse events was reported.Results The scores of HAMD-17 at baseline and after treatment were 6.60±1.87 and 5.85±4.18,scores of HAMA were 6.36±3.02 and 4.93±3.09,scores of CGI-S were 1.49±0.56 and 1.29±0.81,scores of ASEX were 15.92±4.72 and 15.57±5.26,with significant difference(P＜0.05).After continuation treatment,the remission rate was 54.59％(202 cases/370 cases),and the recurrence rate was 6.49％(24 cases/370 cases),the recurrence time was(64.67±42.47)days.The incidence of treatment-related adverse events was 15.35％(64 cases/417 cases).Conclusion Morinda officinalis oligosaccharides capsules can be effectively used for the continuation treatment of mild and moderate depression,and are well tolerated and safe.

ObjectiveTo investigate the effect of mucin 1 (MUC1) on the proliferation and apoptosis of nasopharyngeal carcinoma (NPC) and its regulatory mechanism. MethodsThe 60 NPC and paired para-cancer normal tissues were collected from October 2020 to July 2021 in Quanzhou First Hospital. The expression of MUC1 was measured by real-time quantitative PCR (qPCR) in the patients with PNC. The 5-8F and HNE1 cells were transfected with siRNA control (si-control) or siRNA targeting MUC1 (si-MUC1). Cell proliferation was analyzed by cell counting kit-8 and colony formation assay, and apoptosis was analyzed by flow cytometry analysis in the 5-8F and HNE1 cells. The qPCR and ELISA were executed to analyze the levels of TNF-α and IL-6. Western blot was performed to measure the expression of MUC1, NF-кB and apoptosis-related proteins (Bax and Bcl-2). ResultsThe expression of MUC1 was up-regulated in the NPC tissues, and NPC patients with the high MUC1 expression were inclined to EBV infection, growth and metastasis of NPC. Loss of MUC1 restrained malignant features, including the proliferation and apoptosis, downregulated the expression of p-IкB、p-P65 and Bcl-2 and upregulated the expression of Bax in the NPC cells. ConclusionDownregulation of MUC1 restrained biological characteristics of malignancy, including cell proliferation and apoptosis, by inactivating NF-κB signaling pathway in NPC.

Objective Cognitive impairment(CI)in older individuals has a high morbidity rate worldwide,with poor diagnostic methods and susceptible population identification.This study aimed to investigate the relationship between different retinal metrics and CI in a particular population,emphasizing polyvascular status. Methods We collected information from the Asymptomatic Polyvascular Abnormalities Community Study on retinal vessel calibers,retinal nerve fiber layer(RNFL)thickness,and cognitive function of 3,785 participants,aged 40 years or older.Logistic regression was used to analyze the relationship between retinal metrics and cognitive function.Subgroups stratified by different vascular statuses were also analyzed. Results RNFL thickness was significantly thinner in the CI group(odds ratio:0.973,95%confidence interval:0.953-0.994).In the subgroup analysis,the difference still existed in the non-intracranial arterial stenosis,non-extracranial carotid arterial stenosis,and peripheral arterial disease subgroups(P<0.05). Conclusion A thin RNFL is associated with CI,especially in people with non-large vessel stenosis.The underlying small vessel change in RNFL and CI should be investigated in the future.
