The areas of S. japonicum-infected snail habitats appeared an average annual reduction of 47.09% in Wuhan City from 2005 to 2023 [AAPC = -47.09%, 95% CI: (-52.92%, -38.26%), P < 0.01], with two joinpoints in 2011 and 2014, respectively, and the tendency towards a decline showed statistical significance during the period from 2011 through 2014 [APC = -97.27%, 95% CI: (-98.65%, -88.06%), P < 0.01]. The areas of snail habitats in inner embankments appeared an average annual reduction of 4.45% in Wuhan City from 2005 to 2023 [AAPC = -4.45%, 95% CI: (-5.18%, -3.82%), P < 0.01], with three joinpoints in 2011, 2015 and 2018, respectively, and statistical significance was seen in the tendency towards a decline during the period from 2005 through 2011 [APC = -16.38%, 95% CI: (-20.15%, -14.25%), P < 0.01]. In addition, the actual areas of snail habitats appeared an average annual reduction of 2.65% in Wuhan City from 2005 to 2023 [AAPC = -2.65%, 95% CI: (-2.89%, -2.40%), P < 0.01], with a joinpoint in 2013, and the tendency towards a decline showed statistical significance during the period from 2013 through 2023 [APC = -4.06%, 95% CI: (-4.66%, -3.58%), P < 0.01]. Conclusions The integrated schistosomiasis control programme achieved significant effectiveness in Wuhan City from 2005 to 2023, with a tendency towards a decline in morbidity due to schistosomiasis in humans and livestock and snail status. The integrated schistosomiasis control strategy with emphasis on management of the source of S. japonicum infections should continue to be implemented to consolidate the schistosomiasis control achievements and achieve the goal of schistosomiasis elimination in the city.

BackgroundAs a high prevalence disorder， schizophrenia has caused significant burden to family and society due to the impairment of occupational and social function. Currently， the dominant vocational training model in China follows a paternalistic， clinician-led decision-making approach. Although it improves patients' social function to some extent， it undermines their autonomy and treatment adherence. Therefore， it is urgently necessary to explore a new intervention method to enhance treatment compliance and social function in patients. ObjectiveTo explore the impact of shared decision-making oriented vocational training on social function in hospitalized schizophrenia patients， so as to provide references for rehabilitation interventions. MethodsA total of 68 patients diagnosed with schizophrenia according to the International Classification of Diseases， tenth edition （ICD-10） criteria were consecutively enrolled from January to June 2024 at The Third People's Hospital of Wenjiang Distric， Chengdu. Participants were randomly allocated into the research group （n=34） and the control group （n=34） using a random number table method. Both groups received routine rehabilitation training， while the research group received shared decision-making oriented vocational training for 12 weeks， 2 times a week for 2 hours each time. Before and at the 4^th and 12^th week of intervention， two groups were evaluated by General Self-Efficacy Scale （GSES）， Stigma Scale for Mental Illness （SSMI）， Scale of Social function of Psychosis Inpatients （SSFPI） and Inpatient Psychiatric Rehabilitation Outcome Scale （IPROS）. ResultsA total of 63 participants completed the study， with 30 cases in the research group and 33 cases in the control group. Repeated measures ANOVA revealed statistically significant time effects and interaction effects in both groups for GSES， SSMI， SSFPI and IPROS scores （F=20.451， 16.022； 26.193， 12.944； 23.957， 5.023； 11.776， 3.985， P<0.05 or 0.01）， while no significant group effects were observed （F=0.188， 0.742， 1.878， 0.474， P>0.05）. At the 12^th week of intervention， there were statistically significant differences in GSES， SSMI， SSFPI and IPROS scores between the two groups. ConclusionShared decision-making oriented vocational training may help to improve social function in patients with schizophrenia. ［Funded by 2023 Chengdu Medical Research Project （number， 2023468）］

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 observe the safety and effectiveness of single dose intravenous infusion of tranexamic acid(TX-A)in dual level posterior lumbar interbody fusion(PLIF),and to explore the changes and trends in perioperative white blood cell(WBC),erythrocyte sedimentation rate(ESR),and C-reactive protein(CRP).Methods Between October 2020 and September 2022,46 patients with lumbar degenerative disease were treated with dual level PLIF,including 18 males and 28 females,with an average age of(60.24±10.68)years old,from 34 to 80 years old.They were divided into observation group and control group according to different treatment methods.There were 28 patients in the observation group,including 12 males and 16 females,with an average age of(61.04±9.03)years old.There were 3 cases with lumbar disc herniation(LDH),lumbar spinal stenosis(LSS)18 cases,lumbar spondylolisthesis(LS)7 cases.TXA(1 g/100 ml)was administered intravenously 15 min before skin incision after general anesthesia.The control group consisted of 18 patients,including 6 males and 12 females,with an average age of(59.00±13.04)years old.There were 5 cases with LDH,LSS 9 cases,LS 4 cases,and TXA was not used.The operation time,intraoperative bleeding volume,postoperative drainage volume,postoperative deep vein thrombosis(DVT),postoperative hospital stay,postoperative activated partial thromboplastin time(APTT),prothrombin time(PT),thrombin time(TT),fibrinogen(FIB),platelet(PLT),red blood cell(RBC),hemoglobin(HB),hematocrit(HCT),the first day,the fourth day,the seventh day and the last tested after operation WBC,ESR and CRP were recorded.Results The postop-erative wounds of the patients healed well and there was no DVT.46 patients were followed up from 3 to 6 months.The intraop-erative blood loss was 400.0(300.0,500.0)ml and the postoperative drainage was 260.0(220.0,450.0)ml in the observation group,which were lower than the control group[600.0(400.0,1000.0)ml,395.0(300.0,450.0)ml],P＜0.05.There was no significant difference between the two groups in operation time,postoperative hospital stay,postoperative APTT,PT,TT,FIB,PLT,RBC,HB,HCT,and postoperative WBC,ESR and CRP at different times(P＞0.05).Conclusion Single dose intravenous infusion of TXA can reduce the blood loss of bi-segmental PLIF,and has no significant effect on WBC,ESR and CRP after op-eration.

Objective To investigate the effect of pristimerin(PM)on adriamycin(ADM)resistance in osteosarcoma cells and its mechanism.Methods The ADM resistant cells MG-63/ADR was established in vitro by using the ADM increasing concentration gradient long-term culture method,CCK-8 was used to detect the effects of different concentrations of ADM on the viability of osteosarcoma cells MG-63 and MG-63/ADR cells to verify the drug resistance of ADM;subsequently,MG-63/ADR cells were randomly divided into the MG-63/ADR group(normal culture),low-dose PM group(adding 0.5 μmol/L PM),middle-dose PM group(adding 1.0 μmol/L PM)and high-dose PM group(adding 2.0 μmol/L PM).The cell viability of each group under different concentrations of ADM treatment was detected by CCK-8;the sensitivity of cells to ADM in each group was detected by plate clone formation assay;the cell morphology of each group was observed under microscope;the cell apoptosis level was detected by flow cytometry;Western blot was used to detect the expression of phosphorylated mammalian STE20-like protein kinase 1(p-MST1),MST1,phosphorylated large tumor suppressor 1(p-LATS1),LATS1,phosphorylated Yes associated protein(p-YAP)and YAP proteins.Results With the intervention of 25,125,625,3 125 and 15 625 ng/mL ADM,the activity of MG-63/ADR cells was significantly higher than that of MG-63 cells(P＜0.05),which indicated that the ADM resistant cell model was successfully established.Compared with the MG-63/ADR group,the number of cells in the low,middle and high-dose PM groups decreased,and the cells gradually shrank,the spacing between cells became larger,and the cell viability,cell clonal formation rate and p-YAP/YAP level decreased(P＜0.05),the apoptosis rate and the levels of p-MST1/MST1 and p-LATS1/LATS1 significantly increased(P＜0.05).Conclusion The inhibitory effect of PM on ADM resistance in osteosarcoma cells may be related to the activation of Hippo pathway and the downregulation of YAP signal.

Objective We aimed to compare the efficacy and prognosis of percutaneous coronary intervention(PCI)in complex and high-risk patients with coronary heart disease(CHD)treated with extracorporeal membrane oxygenation(ECMO)combined with intra-aortic balloon pump(IABP)assistance,and explore the application value of combined use of mechanical circulatory support(MCS)devices in complex PCI.Methods A total of patients who met the inclusion criteria and underwent selective PCI supported by MCS at the Department of Cardiology,the First Affiliated Hospital of the Air Force Medical University from January 2018 to December 2022 were continuously enrolled.According to the mechanical circulatory support method,the patients were divided into ECMO+IABP group and IABP group.Clinical characteristics,angiographic features,in-hospital outcomes,and complications were collected.The intra-hospital outcomes and major adverse cardiovascular events(MACE)at one month and one year after the procedure were observed.The differences and independent risk factors between the two groups in the above indicators were analyzed.Results A total of 218 patients undergoing elective PCI were included,of which 66 patients were in the ECMO+IABP group and 152 patients were in the IABP group.The baseline characteristics of the two groups of patients were generally comparable,but the ECMO+IABP group had more complex lesion characteristics.The proportion of patients with atrial fibrillation(6.1％vs.0.7％,P=0.030),left main disease(43.9％vs.27.0％,P=0.018),triple vessel disease(90.9％vs.75.5％,P=0.009),and RCA chronic total occlusion disease(60.6％vs.35.5％,P＜0.001)was higher in the ECMO+IABP group compared to the IABP group.The proportion of patients with previous PCI history was higher in the IABP group(32.9％vs.16.7％,P=0.014).There was no statistically significant difference in the incidence of in-hospital complications between the two groups(P=0.176),but the incidence of hypotension after PCI was higher in the ECMO+IABP group(19.7％vs.9.2％,P=0.031).The rates of 1-month MACE(4.5％vs.2.6％,P=0.435)and 1-year MACE(7.6％vs.7.9％,P=0.936)were comparable between the two groups.Multivariate analysis showed that in-hospital cardiac arrest(OR 7.17,95％CI 1.27-40.38,P=0.025)and after procedure hypotension(OR 3.60,95％CI 1.10-11.83,P=0.035)were independent risk factors for the occurrence of 1-year MACE.Conclusions Combination use of ECMO+IABP support can provide complex and high-risk coronary heart disease patients with an opportunity to achieve coronary artery revascularization through PCI,and achieve satisfactory long-term prognosis.

Objective:To evaluate the difference in efficacy between liposuction combined with single-port endoscopic subcutaneous adenomectomy and traditional open surgery in treating adolescent male breast development disorder,and to compare their effects on patients'anxiety levels and quality of life.Methods:A total of sixty-four patients with adolescent male mammary gland dysplasia who underwent surgery at our hospital between March 2022 and June 2023 were included in this retrospective analysis,with 28 cases in the open surgery group and 36 cases in the single-hole endoscopic group.The study compared various parameters including surgery duration,intraoperative bleeding,incision length,hospitalization duration,treatment cost,and postoperative complications,alongside collecting GAD-7,SF-36,and SCAR questionnaire scores from the pa-tients.Results:The single-port endoscopy group,in comparison to the open surgery group,showed a slightly longer operation time and higher treatment cost but had a shorter hospitalization duration and smaller incision.There was no significant difference observed between the two groups concerning intraoperative bleeding.Notably,the single-port endoscopy group exhibited more significant improvements in SCAR,SF-36,and GAD-7 scores(P＜0.05).Conclusion:Com-pared with traditional open surgery,liposuction combined with single-port endoscopic subcutane-ous adenomectomy is more effective in treating adolescent gynecomastia.This approach not only offers better aesthetic outcomes but also proves effective in reducing patient anxiety and signifi-cantly enhancing their quality of life.

Objective To compare the biomechanical properties of new type of unicortical and unilateral external fixators by finite element analysis.Methods Firstly,a tibia model was reconstructed based on the CT data images using Mimics software,and then processed and modified by Geomagic Wrap software.Secondly,Solidworks software was used to establish the 3D models for new type of unicortical and unilateral external fixators,and fracture defect was made in the tibia model and then the model was assembled with the external fixators.Finally,mesh delineation was performed using ABAQUS software,and axial compression,torsion and bending loads were applied to the assemblies,respectively,to observe the stress distributions and fracture displacements and to evaluate the biomechanical properties of the 2 types of external fixators.Results The new type of unicortical external fixator had the mean and maximum stresses at the nail-bone interface and the stress distribution at the pin-bone contact surface lower than those of the unilateral external fixator under the three different loads,which behaved better in torsional resistance while worse in axial compression and bending resistance than the unilateral external fixator.Conclusion The new type of unicortical external fixator has the biomechanical stability slightly weaker than that of the unilateral external fixator,which shows sufficient stability and reasonable load distribution when used for temporary fixation with lower likelihood of nail breaking,periprosthetic fractures of the tibia pin tract and loosening of the bone pins when compared with the unilateral external fixator.[Chinese Medical Equipment Journal,2024,45(11):32-38]

Objective:This study aims to compare the antiviral treatment similarities and differences in the population covered by the 2024 version of the World Health Organization's (WHO) hepatitis B prevention and treatment guidelines and the current Chinese hepatitis B prevention and treatment guidelines, so as to explore their impact on the indications for antiviral therapy in Chinese patients with chronic hepatitis B (CHB).Methods:The information of patients with chronic hepatitis B virus infection who did not receive antiviral treatment was collected through the registration database of the China Clinical Research Platform for Hepatitis B Elimination. Descriptive statistics were conducted on the demographic, blood, biochemical, and virological levels of patients according to the treatment recommendations of the two versions of the guidelines. The Mann-Whitney U test and χ2 test were used to compare the differences and proportional distribution of the treatment populations covered by the two guidelines. The χ2 test was used to analyze the coverage rate of different antiviral treatment indications.Results:A total of 21,134 CHB patients without antiviral treatment were enrolled. 69.4% of patients met the 2024 versions of the WHO guidelines' recommendations. 85.0% of patients met the current Chinese hepatitis B prevention and treatment guidelines. The WHO guidelines for antiviral therapy indications were met in younger patients with higher levels of ALT, AST, and APRI scores, as well as greater proportion of patients with higher viral loads (P<0.001). The WHO guidelines recommended a cut-off value of APRI>0.5, which raised the proportion of patients on antiviral therapy from 6.6% to 30.9%. 45.7% of patients met the antiviral indications for HBV DNA >2000 IU/ml with abnormal transaminase (ALT>30 U/L for males and ALT>19 U/L for females). The reduced APRI diagnostic cut-off value and ALT treatment threshold had further increased the treatment coverage rate by 91.6% in patients with chronic HBV infection in line with the 2024 versions of WHO guidelines.Conclusion:The reduction of the APRI diagnostic cut-off value and the ALT treatment threshold, based on the current hepatitis B guidelines of China, will further improve the treatment coverage of CHB patients.

Objective:To compare the efficacy of percutaneous vertebroplasty (PVP) under enhanced regional and conventional anesthesia for multisegmental acute symptomatic osteoporotic thoracolumbar fractures (m-ASOTLF).Methods:A retrospective cohort study was conducted to analyze the data of 91 patients with m-ASOTLF who were admitted to Honghui Hospital of Xi′an Jiaotong University from January 2021 to December 2022, including 36 males and 55 females, aged 55-80 years [(67.4±7.3)years]. According to American Society of Anesthesiologists (ASA) classification system, 18 patients were classified as grade I, 52 grade II, and 21 grade III. Injured segments included T 6-T 10 in 23 patients, T 11-L 2 in 47 and L 3-L 5 in 21. All the patients were treated with PVP, among whom 45 were given enhanced regional anesthesia (enhanced anesthesia group) and 46 regional conventional anesthesia (conventional anesthesia group). The following indicators were compared between the two groups: the operation time, intraoperative bleeding, intraoperative heart rate, intraoperative mean arterial pressure (MAP), number of intraoperative fluoroscopies, and total amount of bone cement injected; the visual analogue scale (VAS) and Oswestry dysfunction index (ODI) before surgery, at 1 day, 1 month after surgery and at the last follow-up; the mini-mental state examination (MMSE) before surgery, at 1, 6, and 12 hours after surgery; the anterior vertebrae height (AVH), middle vertebrae height (MVH), and vertebral kyphosis angle (VKA) before and at 1 day after surgery; the incidence of complications such as bone cement leakage. Results:All the patients were followed up for 12-20 months [(15.8±2.6)months]. There were no significant differences between the two groups in the operation time, intraoperative bleeding, intraoperative heart rate, intraoperative MAP, number of intraoperative fluoroscopies or total amount of bone cement injected ( P>0.05). No significant differences were found between the two groups in VAS or ODI before surgery and at the last follow-up ( P>0.05). The VAS scores in the enhanced anesthesia group were (2.5±0.4)points and (1.8±0.3)points at 1 day and 1 month postoperatively respectively, which were both lower than (3.5±0.4)points and (2.0±0.5)points in the conventional anesthesia group ( P<0.01). The ODI values in the enhanced anesthesia group were 39.8±3.3 and 26.5±5.0 at 1 day and 1 month postoperatively respectively, which were both lower than 43.8±7.5 and 30.3±6.4 in the conventional anesthesia group ( P<0.01). The VAS and ODI at all postoperative time points decreased in both groups compared with those before surgery, with significant differences among those at all postoperative time points ( P<0.05). There was no significant difference between the two groups in the MMSE scores before, at 1, 6, and 12 hours after surgery ( P>0.05). The MMSE scores at 1 and 6 hours postoperatively were lower than that preoperatively in both groups ( P<0.05), and it was increased at 6 hours compared with that at 1 hour postoperatively ( P<0.05). There was no significant difference between the MMSE scores at 12 hours postoperatively and preoperatively in both groups ( P>0.05). The differences between the two groups in AVH, MVH, or VKA preoperatively were not statistically significant ( P>0.05). The AVH and MVH at 1 day postoperatively in the enhanced anesthesia group were (22.4±4.2)mm and (22.7±3.7)mm respectively, which were both higher than those in the conventional anesthesia group [(19.3±3.7)mm and (20.1±6.3)mm] ( P<0.05 or 0.01); the VKA at 1 day postoperatively in the enhanced anesthesia group was (13.9±3.7)°, which was lower than that in the conventional anesthesia group (15.8±4.1)° ( P<0.05). The AVH, MVH, and VKA in both groups were all improved at 1 day postoperatively compared with those preoperatively ( P<0.05). The incidence of bone cement leakage in the enhanced anesthesia group was 6.7% (3/45), which was lower than 21.7% (10/46) in the conventional anesthesia group ( P<0.05). Conclusion:Compared with conventional regional anesthesia, PVP under enhanced regional anesthesia for m-ASOTLF has more advantages in early postoperative pain relief, improvement of spinal function, restoration of vertebral height and reduction of bone cement leakage.
