Objective: To establish a prediction model for high-risk cardiovascular disease (CVD) among residents aged 35 to 75 years, so as to provide the basis for improving CVD prevention and control measures. Methods: Permanent residents aged 35 to 75 years were selected from Dongcheng District, Beijing Municipality using the stratified random sampling method from 2018 to 2023. Demographic information, lifestyle, waist circumference and blood biochemical indicators were collected through questionnaire surveys, physical examinations and laboratory tests. Influencing factors for high-risk CVD among residents aged 35 to 75 years were identified using a multivariable logistic regression model, and a prediction model for high-risk CVD was established. The predictive effect was evaluated using the receiver operating characteristic (ROC) curve. Results: A total of 6 968 individuals were surveyed, including 2 821 males (40.49%) and 4 147 females (59.51%), and had a mean age of (59.92±9.33) years. There were 1 155 high-risk CVD population, with a detection rate of 16.58%. Multivariable logistic regression analysis showed that gender, age, smoking, central obesity, systolic blood pressure, fasting blood glucose, triglyceride and low-density lipoprotein cholesterol were influencing factors for high-risk CVD among residents aged 35 to 75 years (all P<0.05). The area under the ROC curve of the established prediction model was 0.849 (95%CI: 0.834-0.863), with a sensitivity of 0.693 and a specificity of 0.863, indicating good discrimination. Conclusion The model constructed by eight factors including demographic characteristics, lifestyle and blood biochemical indicators has good predictive value for high-risk CVD among residents aged 35 to 75 years.

Objective To observe the effect of knee isometric training on mild to moderate lower limb muscle spasticity in stroke patients.Methods A total of 130 stroke hemiplegia patients were prospectively included in this study.They were admitted to Xiangcheng People's Hospital of Suzhou City between August 2021 and December 2023 and numbered according to the order of collection.The patients were then randomly assigned to either the control group or the isokinetic group using a random number table.Each group consisted of 65 cases.Both groups underwent conventional rehabilitation training(5 days a week,40 minutes per day),with the isokinetic group receiving additional isokinetic muscle training(5 days a week,20 minutes per day)on top of the conventional rehabilitation training.The treatment period lasted for 6 weeks.The surface electromyographic signals of the rectus femoris muscle on the affected side were analyzed for their root-mean-square(RMS),integral electromyographic(iEMG)values,the modified Ashworth scale(MAS)scores,knee flexors and extensors peak torque and its ratio,the Fugl-Meyer assessment scale-lower extremity(FMA-LE)scores,and the 10 m walk test were used before and after the treatments to compare the surface electromyography of rectus femoris,the degree of muscle spasticity and exercise capacity of the lower extremities of the two groups.Results Prior to treatment,there were no statistically significant differences between the two groups in terms of the RMS of the rectus femoris muscle,iEMG values,MAS scores,peak torque of the flexor and extensor muscles and their ratio,FMA-LE score,and step speed(all P＞0.05).RMS of the rectus femoris muscle,iEMG values,MAS scores,peak torque of the knee flexors and extensors and their ratios,FMA-LE scores,and step speed improved in control group after treatment compared to before treatment([12.3±2.2]μV vs.[15.5± 2.9]μV,[24.8±2.3]μV·s vs.[29.2±3.1]μV·s,[1.34±0.15]points vs.[1.56± 0.25]points,[20.8±3.4]N·m vs.[12.3±2.5]N·m,[34.5±2.3]N·m vs.[26.3±3.6]N·m,0.60±0.16 vs.0.47±0.14,[26.1±2.9]points vs.[21.3±2.4]points,[0.61±0.14]m/s vs.[0.46±0.15]m/s;all P＜0.05).Rectus femoris muscle RMS,iEMG values,MAS scores,peak torque of the flexor and extensor muscles and their ratio,FMA-LE scores and step speed after treatment in the isokinetic group were(10.9±1.8)μV,(22.4±2.1)μV·s,(1.25±0.18)points,(28.7±3.0)N·m,(41.5±2.8)N·m,0.69±0.18,(29.0±2.3)points,(0.69±0.18)m/s,compared with pretreatment(respectively[15.4±2.2]μV,[29.6±3.0]μV·s,[1.58±0.34]points,[12.6± 2.3]N·m,[26.1±3.1]N·m,0.48±0.17,[21.5±2.1]points,[0.48±0.17]m/s)and control group after treatment,the differences were statistically significant(all P＜0.05).Before treatment,the differences in rectus femoris muscle RMS and iEMG values between patients with mild spasticity and patients with moderate spasticity in the isokinetic group and the corresponding patients with mild spasticity and moderate spasticity within the control group were not statistically significant(all P＞0.05).After treatment,the rectus femoris muscle RMS and iEMG values in patients with mild spasticity within the isokinetic group([10.2±1.0]μV and[20.2±2.0]μV·s,respectively)were statistically different from those before treatment([14.1±2.3]μV and[28.1±3.2]μV·s,respectively)and those after treatment in patients with mild spasticity within the control group([11.4±1.7]μV and[23.6±2.5]μV·s respectively;all P＜0.05);the rectus femoris muscle RMS and iEMG values in patients with moderate spasticity within the isokinetic group improved compared with the pre-treatment period([11.8±1.5]μV vs.[16.9±2.6)μV,and[24.9±2.2]μV·s vs.[31.3±3.8]μV·s,respectively;both P＜0.05),and with the control group after treatment(RMS and iEMG values of[13.2±2.5]μV and[26.1± 2.7]μV·s,respectively),the difference in RMS was statistically significant(P＜0.01),and the difference in iEMG values was not statistically significant(P＞0.05).Conclusion Isokinetic muscle training has a positive effect on improving mild-to-moderate muscle spasticity of the lower limb knee extension,and the effect is more significant the lighter the degree of spasticity.

Aim To screen and study the effects of Tao Hong Si Wu decoction(THSWD)-mediated treat-ment on circular RNA(circRNA)expression profiles in rats with middle cerebral artery occlusion(MCAO),and investigate the possible roles and molecular mecha-nisms of THSWD.Methods Next-generation RNA sequencing was conducted to identify circRNA expres-sion profiles in MCAO rats after treatment with THSWD and compared with the MCAO model group and control group.Bioinformatics analysis was performed to predict the potential target microRNAs and mRNAs.Gene On-tology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analyses for the potential target mRNAs were applied to explore the potential roles of differentially expressed circRNAs.RT-qPCR was performed to verify circRNAs with significant differences in expression.Results We identified 87 significantly differentially expressed circRNAs between the MCAO group versus the control group,and 86 sig-nificantly differentially expressed circRNAs between the MCAO group versus the THSWD group.respective-ly.Among them,17 circRNAs induced by the MCAO model were reversed via treatment with THSWD.To demonstrate the roles of mRNAs targeted by DECs,the GO and KEGG databases were used.Further analysis revealed that five circRNAs may play important roles in the development of MCAO.Conclusions The com-prehensive expression profile of circRNAs in rats with middle cerebral artery occlusion after THSWD treat-ment is determined for the first time,suggesting that the therapeutic effect of THSWD on MCAO may be a-chieved by regulating the expression of circRNAs.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To analyze the incidence and clinical phenotype of the concomitant extragenital malformations in the patients with female reproductive tract anomalies.Methods:A retrospective study was conducted using clinical data of hospitalized patients diagnosed with uterine, cervical, or vaginal malformations from January 2003 to December 2022 in Peking Union Medical College Hospital. The malformations were classified according to American Society for Reproductive Medicine müllerian anomalies classification 2021, and in each type, the incidence and specific manifestations of concomitant extragnital malformations were analyzed.Results:A total of 444 patients were included. The overall incidence of concomitant extragenital malformations was 43.5% (193/444), including urinary system, skeletal system, and other system malformations. Renal malformations on the obstructed side were present in all patients with oblique vaginal septum syndrome (100.0%, 78/78). The total incidence of concomitant extragnital malformations was as high as 8/11 in uterus didelphys, 43.5% (10/23) in unicornuate uterus, 33.6% (79/235) in Mayer-Rokitansky-Küster-Hauser syndrome, 18.8% (6/32) in septate uterus and 18.5% (12/65) in cervical agenesis. Urinary system malformations (30.6%, 136/444) and skeletal system malformations (13.5%, 60/444) were the most common concomitant malformations in all types, in which, unilateral renal agenesis and scoliosis were the most common.Conclusions:Urinary and skeletal system malformations are important features of female reproductive tract anomalies. Urologic ultrasonography and spinal roentgenogram are recommended for all patients with female reproductive tract anomalies.

Objective:To evaluate the efficacy and safety of unilateral adrenalectomy for treating primary bilateral macronodular adrenal hyperplasia (PBMAH) of different clinical types.Methods:The clinical and biochemical data of 54 patients with PBMAH who underwent unilateral adrenalectomy from May 2008 to March 2023 were retrospectively collected. Preoperative CT images of all patients showed enlarged bilateral adrenal glands with multiple nodules of " fused masses". Mean preoperative blood cortisol concentration at 8am was (21.5±7.7)μg/dl, urinary free cortisol concentration was (442.6±300.4)μg/24h, and mean 8am ACTH concentration was (6.4±2.3)pg/ml. Postoperative symptoms, BMI, blood pressure, mass diameter, cortisol and ACTH concentration were recorded and analyzed.Results:Compared with ordinary laparoscopic surgery, robot-assisted surgery showed shorter operation time [(115.4±22.1)min vs.(95.0±19.8)min, P=0.045]; less blood loss [(118.2±57.0)ml vs. (125.6±45.3)ml, P=0.441] and shorter hospitalization time [(5.2±0.9)day vs. (6.4±1.2)day, P=0.279]. Compared with laparoscopic surgery, open surgery showed longer operation time [(134 34.5) min vs. (104.3±20.1) min, P=0.035]; more blood loss [(305.5±85.2) ml vs. (122.5±44.3) ml, P=0.012] and longer hospitalization time[(10.4±3.2)day vs. (5.7±1.0) day, P=0.020]. The average follow-up time was (23.7±11.7) months. Sixteen cases biochemically relapsed, and the average relapse-free time was (25.4±13.4) month. Mean postoperative systolic blood pressure was (131.1±16.8)mmHg ( P=0.001) while diastolic blood pressure decreased to (82.2±11.1)mmHg ( P=0.002). Postsurgical average blood cortisol concentration decreased to (10.2±4.0)μg/dl ( P<0.01), while urine cortisol concentration decreased to (106.6±43.4)μg/24h( P<0.01). Average ACTH concentration increased to (12.6±4.1)pg/ml( P=0.005). Recurrent patients had higher preoperative blood and urine cortisol concentration(24.7±8.2)μg/dl( P=0.046), (522.8±234.2)μg/24h( P=0.028), and all of them underwent contralateral adrenalectomy. Conclusions:Unilateral adrenalectomy is safe and effective for treatment of PBMAH while part of patients biochemically relapsed. Subclinical patients were observed no recurrent cases after surgery. Recurrent patients have higher preoperative blood and urine cortisol levels and should undertake contralateral adrenalectomy and supplement corticosteroids for whole life.

Background/Aims: Despite the high efficacy of direct-acting antivirals (DAAs), approximately 1–3% of hepatitis C virus (HCV) patients fail to achieve a sustained virological response. We conducted a nationwide study to investigate risk factors associated with DAA treatment failure. Machine-learning algorithms have been applied to discriminate subjects who may fail to respond to DAA therapy. Methods: We analyzed the Taiwan HCV Registry Program database to explore predictors of DAA failure in HCV patients. Fifty-five host and virological features were assessed using multivariate logistic regression, decision tree, random forest, eXtreme Gradient Boosting (XGBoost), and artificial neural network. The primary outcome was undetectable HCV RNA at 12 weeks after the end of treatment. Results: The training (n=23,955) and validation (n=10,346) datasets had similar baseline demographics, with an overall DAA failure rate of 1.6% (n=538). Multivariate logistic regression analysis revealed that liver cirrhosis, hepatocellular carcinoma, poor DAA adherence, and higher hemoglobin A1c were significantly associated with virological failure. XGBoost outperformed the other algorithms and logistic regression models, with an area under the receiver operating characteristic curve of 1.000 in the training dataset and 0.803 in the validation dataset. The top five predictors of treatment failure were HCV RNA, body mass index, α-fetoprotein, platelets, and FIB-4 index. The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of the XGBoost model (cutoff value=0.5) were 99.5%, 69.7%, 99.9%, 97.4%, and 99.5%, respectively, for the entire dataset. Conclusions Machine learning algorithms effectively provide risk stratification for DAA failure and additional information on the factors associated with DAA failure.

Background/Aims: Chronic hepatitis C (CHC) patients who failed antiviral therapy are at increased risk for hepatocellular carcinoma (HCC). This study assessed the potential role of metformin and statins, medications for diabetes mellitus (DM) and hyperlipidemia (HLP), in reducing HCC risk among these patients. Methods: We included CHC patients from the T-COACH study who failed antiviral therapy. We tracked the onset of HCC 1.5 years post-therapy by linking to Taiwan’s cancer registry data from 2003 to 2019. We accounted for death and liver transplantation as competing risks and employed Gray’s cumulative incidence and Cox subdistribution hazards models to analyze HCC development. Results: Out of 2,779 patients, 480 (17.3%) developed HCC post-therapy. DM patients not using metformin had a 51% increased risk of HCC compared to non-DM patients, while HLP patients on statins had a 50% reduced risk compared to those without HLP. The 5-year HCC incidence was significantly higher for metformin non-users (16.5%) versus non-DM patients (11.3%; adjusted sub-distribution hazard ratio [aSHR]=1.51; P=0.007) and metformin users (3.1%; aSHR=1.59; P=0.022). Statin use in HLP patients correlated with a lower HCC risk (3.8%) compared to non-HLP patients (12.5%; aSHR=0.50; P<0.001). Notably, the increased HCC risk associated with non-use of metformin was primarily seen in non-cirrhotic patients, whereas statins decreased HCC risk in both cirrhotic and non-cirrhotic patients. Conclusions Metformin and statins may have a chemopreventive effect against HCC in CHC patients who failed antiviral therapy. These results support the need for personalized preventive strategies in managing HCC risk.

Objective: To analyze the relationship between the toilet design and sanitary condition of primary and secondary schools in Chengdu and the epidemic situation of Norovirus infection, so as to provide scientific references for school toilet design and Norovirus prevention and control. Methods: A total of 78 cases of norovirus epidemics from 2019 to 2020 were included in this study. These epidemics happened in 78 schools and the causes were indicated as human-to-human transmission. The Chi square and Mann-Whitney U test were used to compare categorical and continuous data respectively. Unconditional binary Logistic regression was used to examine the multivariate associations. Results: Most epidemics happened from October in 2019 to March in 2020(79.49%, 62 cases), in primary schools (71.79%, 56 cases) and in the center area (52.56%, 41 cases). The median of the case number in each epidemic was 10. Overall, 56 schools (71.79%) were equipped with toilets which were flushed independently, and 22 schools (28.21%) were equipped with toilets which were flushed uniformly. There were 27 schools (34.62%) that did not have enough water taps. Logistic regression analysis found that those with toilets flushed uniformly had a stronger epidemic, compared to the schools with toilets flushed independently( OR=5.53, 95%CI=1.63-18.76, P <0.05). Conclusion In order to prevent intestinal infectious diseases , it is suggested that schools should design or reconstruct independent flushing toilets with adequate faucets.
