Objective: To explore effects and maintenance of school based sexual abuse prevention programs for minors, so as to provide scientific evidences for optimizing intervention design and policy making. Methods: Six Chinese and English databases were searched, including CNKI, Wanfang Database, Medline (via PubMed), Embase, Cochrane Library and Web of Science, with the time frame set from database inception to December 31, 2024. Studies on school based sexual abuse prevention programs for minors were selected, and data on knowledge, attitudes and skills related to sexual abuse prevention were extracted. Meta analysis was performed using Stata 17. Results: A total of 26 studies were included. The Meta analysis results showed that school based sexual abuse prevention programs improved participants knowledge ( SMD=1.24, 95%CI =0.96-1.52), attitudes ( SMD=0.62, 95%CI =0.19-1.04) and skills ( SMD=0.66, 95%CI =0.50-0.83) (all P <0.01). During the overall follow up, the maintenance rates for knowledge, attitudes, and skills were 0.97(95% CI =0.95-1.00), 0.99(95% CI =0.95-1.04) and 1.01(95% CI =0.99-1.04), respectively, with no statistically significant differences (all P >0.05). However, knowledge retention declined significantly when follow up exceeded three months ( R=0.91, 95%CI=0.83-0.99, P <0.01), while skills retention ( R=0.94, 95%CI=0.87-1.02, P = 0.23) remained higher than knowledge and attitudes ( R=0.98, 95%CI=0.96-1.00, P =0.13), demonstrating stronger long term effects. Conclusion School based sexual abuse prevention programs are effective in enhancing participants knowledge, attitudes and skills, but the intervention effects diminish over time, particularly in knowledge retention.

Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

Objective:To investigate the efficacy and safety of a wearable percutaneous tibial nerve stimulator (TTNS) for tibial neuromodulation (TNM) in the treatment of overactive bladder (OAB).Methods:This research utilizes a single-center, prospective, open clinical trial design. Patients with OAB who were treated at the urology outpatient department of Beijing Bo’ai Hospital from July 2023 to June 2024 were enrolled. All patients met the diagnostic criteria for OAB. All patients received a transcutaneous tibial nerve regulation stimulation therapy, with a frequency of 20 Hz and a pulse width of 0.2 ms. The treatment lasted for 30 minutes each session, twice daily, for a duration of 12 weeks. Follow up evaluations were conducted at weeks 4, 8, and 12 after treatment, including a 72-hour voiding diary, Overactive Bladder Symptom Score (OABSS), patient perception of bladder condition scale (PPBC-S) score, American Urological Association Symptom Index (AUA-SI) score, American Urological Association Symptom Index Quality of Life Score (AUA-SI-QOL) score, vital signs, and adverse events.Results:This study included 68 patients, with 28 males and 40 females. Their mean age was (49.6±9.0) years old, the body mass index was(23.2 ± 2.5) kg/m 2. The duration of the disease was(42.0±14.4)months. After 12 weeks of intervention, patient's daily urination frequency decreased from (18.5 ± 3.9) times to (10.3 ± 4.5) times, nocturia frequency decreased from (6.5±2.2) times to (3.9±2.0) times, daily urine leakage decreased from (796.5±140.0) ml to (534.8±135.8)ml, OABSS decreased from (12.6±2.8) to (9.8±3.8), PPBC-S decreased from (5.5±0.6) to (3.8±1.2), AUA-SI decreased from (25.5±2.2) to (16.6±3.6), and AUA-SI-QOL decreased from (5.5±0.5) to (3.7±1.1). The differences in the above indicators before and after treatment were statistically significant ( P<0.05). During the treatment process, there were no serious adverse events related to the equipment, and no neurological related adverse events such as numbness or tingling occurred. Conclusions:The application of wearable percutaneous tibial nerve stimulators in TNM can effectively alleviate OAB symptoms like frequent urination and urgency, with minimal adverse reactions, offering a new treatment option for OAB patients.

Objective To explore the predictive value of novel anthropometric indicators for the long-term prognosis in patients with acute myocardial infarction(AMI).Methods A total of 712 patients diagnosed with AMI in the People's Hospital of Xinjiang Uygur Autonomous Region from January 2018 to December 2019 were selected as research subjects,and divided into an event group and a non-event group according to whether major cardiovascular adverse events(MACEs)occurred during the period of follow-up.Gensini score was used to quanti-tatively assess the degree of coronary artery stenosis.Spearman correlation analysis was used to explore the correla-tion between the new anthropometric indicators and Gensini score.Receiver operating characteristic(ROC)curve was used to evaluate the ability of new anthropometric indicators to predict MACEs,and the patients were grouped according to the optimal cut-off value.Kaplan-Meier curve was used to analyze the survival difference between the groups.Multivariate Cox regression was used to analyze the independent risk factors of MACEs.Results During a median follow-up of 27(20,39)months,a total of 125 patients developed MACEs.As compared with those in the non-event group,the patients in the event group had a higher proportion of hypertension,diabetes and abdominal obesity,higher HbA1c and FBG levels,and longer body weight and waist circumference.The LAP index,CMI index,BRI index and Gensini score were significantly increased,and the differences were statistically significant(P＜0.05).Spearman correlation analysis showed that LAP index,CMI index and BRI index were positively corre-lated with Gensini score(r=0.233,0.126,0.272,P<0.001).ROC curve analysis showed that the AUC of LAP index,CMI index,VAI index,BRI index and ABSI index were 0.745,0.640,0.490,0.874 and 0.506 respec-tively;Kaplan-Meier curve analysis showed that the cumulative incidence of MACEs in LAP index,CMI index and BRI index was significantly increased in the high-value group(Log-rank test,P＜0.05).The results of multivariate Cox regression analysis after adjusting confounding showed that CMI index(HR=1.430,95%CI:1.049～1.952,P=0.024)and BRI index(HR=1.332,95%CI:1.234～1.439,P＜0.001)were independent risk factors for MACEs.Conclusions CMI index and BRI index of new anthropometric indicators are independent risk factors for long-term prognosis in patients with AMI.

Objective To investigate the value of polar residual network(PResNet)model for assisting evaluation on rat myocardial infarction(MI)segment in myocardial contrast echocardiography(MCE).Methods Twenty-five male SD rats were randomly divided into MI group(n=15)and sham operation group(n=10).MI models were established in MI group through ligation of the left anterior descending coronary artery using atraumatic suture,while no intervention was given to those in sham operation group after thoracotomy.MCE images of both basal and papillary muscle levels on the short axis section of left ventricles were acquired after 1 week,which were assessed independently by 2 junior and 2 senior ultrasound physicians.The evaluating efficacy of MI segment,the mean interpretation time and the consistency were compared whether under the assistance of PResNet model or not.Results No significant difference of efficacy of evaluation on MI segment was found for senior physicians with or without assistance of PResNet model(both P＞0.05).Under the assistance of PResNet model,the efficacy of junior physicians for diagnosing MI segment was significantly improved compared with that without the assistance of PResNet model(both P＜0.01),and was comparable to that of senior physicians.Under the assistance of PResNet model,the mean interpretation time of each physician was significantly shorter than that without assistance(all P＜0.001),and the consistency between junior physicians and among junior and senior physicians were both moderate(Kappa=0.692,0.542),which became better under the assistance(Kappa=0.763,0.749).Conclusion PResNet could improve the efficacy of junior physicians for evaluation on rat MI segment in MCE images,shorten interpretation time with different aptitudes,also improve the consistency to some extent.

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 present a method of modeling 3D-printed guide templates (3DPGTs) strictly based on pre-plans for the interstitial implantation brachytherapy of cervical cancer, and elucidate the advantages of 3DPGTs in the interstitial implantation brachytherapy of cervical cancer.Methods:This study retrospectively selected six cases of locally advanced cervical cancer treated with interstitial implantation brachytherapy using 3DPGTs. Based on the CT images of 3DPGTs and pre-plans, the mechanical precision of 3DPGTs was verified through image registration. The dosimetric differences were compared between the 3DPGT treatment plan and the pre-plan/the freehand implantation plan. The dosimetric parameters included the volume and D90 for the high-risk clinical target volume (HR-CTV), and the D2 cm 3, D1 cm 3, and D0.1 cm 3 for the bladder, rectum, intestine, and sigmoid. Results:The 3DPGTs modeled using the method strictly based on pre-plans exhibited relatively high mechanical precision, with deviations all below 1 mm. Regarding the D90 of the HR-CTV, the 3DPGT treatment plan resulted in a dose of (713.37±143.26) cGy, reduced by 6.95% ( z= -1.98, P<0.05) compared to the (766.62±145.97) cGy in the pre-plan, and increased by 107.6% ( z= -1.89, P<0.05) compared to the (343.56±188.72) cGy in the freehand implantation plan. For dosimetric parameters of organs at risk (OARs), no statistical differences were observed ( P>0.05) between the 3DPGT treatment plan and the pre-plan/the freehand implantation plan. Conclusions:The method of modeling 3DPGTs for cervical cancer proposed in this study demonstrates high accuracy. Hence, the dose for the HR-CTV can be substantially increased under the condition that the OARs are protected from over-irradiation.

AIM:To investigate the impact of total flavonoids of Pterocarya hupehensis Skan(PHSTF)on the migration,invasion,and ferroptosis of non-small-cell lung cancer A549 cells.METHODS:The A549 cells were divided into control group,low-,medium-and high-dose(100,150 and 200 μg/mL)PHSTF groups,ferroptosis inhibitor liprox-statin-1(Lip-1)group,and high-dose PHSTF combined with Lip-1 group,each cultured in corresponding media.Cell via-bility was assessed using the CCK-8 assay,while cell migration and invasion abilities were determined through scratch and Transwell assays.Cell lipid peroxidation levels were measured using the glutathione(GSH)assay kit.RT-qPCR was em-ployed to assess the mRNA expression of solute carrier family 7 member 11(SLC7A11)and glutathione peroxidase 4(GPX4),while Western blot was utilized to examine the protein expression of SLC7A11,GPX4,Kelch-like epichlorohy-drin-associated protein-1(Keap-1),nuclear factor E2-related factor 2(Nrf2)and heme oxygenase-1(HO-1).RE-SULTS:Compared with control group,PHSTF significantly diminished the viability of A549 cells in a time-and dose-de-pendent manner(P＜0.01),and the cell migration and invasion were also reduced(P＜0.01),along with a significant de-crease in GSH level(P＜0.01).Treatment with PHSTF inhibited the mRNA and protein expression levels of ferroptosis-re-lated proteins,including SLC7A11 and GPX4(P＜0.01),suppressed the protein expression of Nrf2 and HO-1(P＜0.01),and enhanced the expression of Keap-1(P＜0.01).The Lip-1 partially restored the decrease in cell viability in-duced by PHSTF(P＜0.01),significantly up-regulated the protein expression levels of SLC7A11,GPX4,Nrf2 and HO-1,and suppressed the protein expression of Keap-1(P＜0.01).CONCLUSION:Total flavonoids of Pterocarya hupehen-sis Skan can inhibit the migration and invasion of non-small-cell lung cancer A549 cells,and induce the cell ferroptosis by regulating the Keap-1/Nrf2/HO-1 pathway.

Objective To investigate the safety and efficacy of totally no tube three-port thoracoscopic surgery (TNTT) for thymic tumor via lateral thoracic approach. Methods The clinical data of patients with thymoma admitted to the Department of Thoracic Surgery of the General Hospital of Northern Theater Command from November 2021 to May 2022 were retrospectively analyzed. The patients were divided into a TNTT group and a single utility port video-assisted thoracic surgery (SVATS) group according to different surgical methods. The clinical data were compared between the two groups. Results A total of 111 patients were collected. There were 44 patients in the TNTT group, including 20 males and 24 females, with an average age of 60.11±8.64 years, and 67 patients in the SVATS group, including 30 males and 37 females, with an average age of 62.40±7.92 years. There was no significant difference between the two groups in the baseline data (P>0.05). The postoperative hospital stay and intraoperative blood loss were shorter or less in the TNTT group (P<0.05), and the visual analogue scale score 48 hours after the operation was smaller in the SVATS group (P<0.05). Conclusion TNTT has a good surgical safety, and can shorten postoperative hospital stay, reduce intraoperative blood loss, and has significant advantages in enhanced recovery after surgery, but SVATS can reduce postoperative pain in patients.
