Ovarian cancer(OC)is a prevalent malignant gynecological tumor with a high mortality rate.The tumor immune microenvironment,consisting of immune components within the tumor microenvironment,plays a significant role in tumor devel-opment and metastasis.OC is typically categorized as a"cold tumor"due to its immunosuppressive microenvironment,resulting in limited efficacy of immunotherapy for this disease.Specifically,the expression of family with sequence similarity 111 member B(FAM111B)protein has been found to be correlated with the immune microenvironment of various tumors,including its associ-ation with the expression of programmed death ligand-1(PD-L1)in ovarian cancer tissues.This review provides an overview of recent research developments concerning the impact of the FAM111B gene on the immune microenvironment of ovarian cancer.

Objective To analyze the prevalence and risk factors of underscreening among cervical cancer screening participants in Wuxiang County,Shanxi Province in 2019,providing evidence-based support for optimizing mobilization strategies.Methods Data from cervical cancer screening programs conducted between 2019 and 2024 in Wuxiang County were retrospectively collected.The follow-up screening behaviors of women screened in 2019 were analyzed,and factors associated with underscreening were identified.Results A total of 3759 women underwent cervical cancer screening in 2019.Among them,492 women(13.09％)with abnormal primary screening results requiring follow-up in 12 months,yet only 43(8.74％)completed;2154 women(57.30％)with negative liquid-based cytology testing(LCT)results needed re-screening after 3 years,701(32.54％)completed;1113 women(29.61％)with negative HPV/combined results needed re-screening after 5 years,734(65.95％)completed.Overall,2299 women(60.69％)exhibited underscreening.Multivariate analysis showed that underscreening was more likely among community residents than rural residents(OR=2.309,P=0.018),older women(OR=1.065,P＜0.001),those in organized screening compared to opportunistic screening(OR=3.789,P＜0.001),those undergoing LCT(OR=4.607,P＜0.001)or combined screening instead of human papillomavirus testing(OR=3.624,P＜0.001),and those with abnormal screening results(OR=6.859,P＜0.001).Conclusion Substantial proportions of cervical cancer screening participants demonstrate poor adherence to guideline-recommended screening intervals,and particularly need to focus on older women and those with abnormal screening results.Implementation of electronic screening record systems and emphasizing knowledge of periodical screening in health education could enhance compliance with"70％screening coverage"target for cervical cancer prevention.

Objective To review the application of sexual dysfunction intervention in cervical cancer patients,and refine the intervention elements,so as to provide ideas and methods for the development of personalized intervention measures.Methods Guided by the 2021 updated methodological guidelines for scoping reviews from the Joanna Briggs Institute in Australia,CINAHL,PubMed,Web of Science,Embase,Cochrane Library,CNKI,Wanfang and VIP databases were systematically searched from inception to February 29,2024,and the included literature were analyzed and summarized.Results A total of 17 studies were included,involving 9 randomized controlled trials,7 quasi-experimental studies and 1 pilot study.The theoretical basis of the intervention includes PLISSIT model,BETTER model,FOCUS program,PERMA flourish theory,empowerment theory,the trans-theoretical model and narrative therapy.The intervention content involves 4 themes:sexual problem disclosing,sexual science education,sexual physiological rehabilitation and sexual psychological rehabilitation.The main forms are offline and online independent or combined intervention.The outcomes include sexual health function,social function,psychological status and self-management.Conclusion Sexual dysfunction interventions have a positive impact on cervical cancer patients.Future research should develop sexual dysfunction interventions with more comprehensive content,richer forms and more accurate evaluation based on the in-depth understanding of the theoretical connotation,and play the role of nurse-led multidisciplinary teams to maintain the long-term sexual and reproductive health of cervical cancer patients.

The study was a prospective observational study. A total of 24 patients who underwent maintenance hemodialysis (MHD) at Haidian Hospital in Beijing from May 2024 to June 2024 were included as the study subjects. The safety and efficacy of a new single-needle dialysis in MHD patients were evaluated. The reasons for using single-needle dialysis included waiting for the maturity of internal fistula(7 cases, 29.17%), autogenous arteriovenous fistula thrombosis occurred (6 cases, 25.00%), puncture difficulty occurred (7 cases, 29.17%), and pain sensitivity or elderly (4 cases, 16.67%). The results showed that the average blood flow was (155.65±5.90) ml/min, total blood volume was (35.92±2.65) L during single-needle dialysis. One patient had slight puncture leakage, and the puncture success rate was 95.83%. Relevant indicators of dialysis adequacy showed that the average urea clearance (Kt/V) was 0.90±0.42, urea reduction ratio was 58.31%±7.93%, and online real-time Kt/V monitoring average value was 0.98±0.55. The results suggest that the application of the new improved single-needle dialysis mode in MHD patients is safe and effective.

Objective:To evaluate the clinical efficacy of the modified medial gastrocnemius myocutaneous flap (MGMF) with extended anterior, posterior and (or) inferior boundaries.Methods:From January 2002 to September 2022, modified MGMFs were applied onto 33 patients who received reconstructive surgery for soft-tissue defects around knee or in calf, in the Department of Orthopaedics, the Second Xiangya Hospital of Central South University. The size of defects ranged from 10 cm×4 cm to 22 cm×12 cm, and the flap size ranged from 15 cm×6 cm to 28 cm×14 cm. Twenty-five patients had the complication of chronic osteomyelitis. The boundaries of a modified MGMF were as follows: the anterior boundary was the anterior border of the tibia, where the posterior boundary at 3.0 cm lateral to the posterior midline, the proximal boundary at the popliteal fossa crease, and the distal boundary at the plane 2.0 cm above the tip of medial malleolus. The anterior edge of the modified MGMF was designed running along the medial edge of the defect and its curved extension line. Pretibial skin was equally divided into 9 zones, with the 1st to 9th zones from proximal to distal in sequence. Postoperative routine anti-infection treatment was offered. All patients were included in the postoperative follow-up through outpatient visits, telephone or WeChat interviews. Flap viability and wound healing in both donor and recipient sites were evaluated. Function of the affected limb was assessed using the evaluation criteria established by Punor et al.Results:All patients were included in the follow-up for 1 to 169 (median duration: 9)months. The 33 modified MGMFs included MGMFs with extended boundary of anterior ( n=18), inferior ( n=5), anterior combined with inferior ( n=6), posterior combined with anterior ( n=2), and posterior combined with inferior ( n=2) boundaries. Twenty-nine (87.9%) flaps survived completely. Partial necrosis occurred in 4 flaps(12.1%)(2 flaps with extended anterior boundary and 2 flaps with extended inferior boundary). The anterior margins of 26 flaps (78.7%) with extended anterior boundary alone or in combination with extended inferior or posterior boundary exceeded the medial edge of the tibia by 1.0-4.5 (mean, 2.1) cm, and 3 of them reached the anterior edge of tibia. Fourteen (42.4%) modified MGMFs were used to reconstruct the defects involving 1/3 of distal calf, and the distal ends of these defects were located in the 7th ( n=8) or 8th ( n= 6) zone. All the skin grafts in the donor sites survived. During follow-up, 31 patients (93.9%) showed no sign of infection, and 2 patients (6.1%) who had recurrence of chronic osteomyelitis. Functions of the affected limbs were excellent ( n=25), good ( n=6) and fair ( n=2) by Punor et al. Conclusion:Modified MGMF with extended anterior, posterior and (or) inferior boundaries is clinically feasible. It offers advantages of easier design and operation. It can be used to reconstruct a more distal, wider and larger defect as well as broadens the application of the MGMF.

Objective:To analyze the epidemiological and clinical characteristics of respiratory pathogens in China.Methods:This study was a cross-sectional study, which encompassed 19 core units of the clinical pathogen network and established a three-tiered clinical pathogen surveillance system. Thirty respiratory samples were collected every two weeks from various units from January to December 2024, and the clinical and pathogen diagnostic information were gathered. A total of 11 864 samples were tested using this system. The tier-1 clinical pathogen surveillance system covered influenza A virus (Flu-A), influenza B virus (Flu-B), respiratory syncytial virus (RSV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The tier-2 clinical pathogen surveillance system focused on 18 key respiratory pathogens. The tier-3 clinical pathogen surveillance system further clarified whether any emerging infectious diseases had occurred.Results:The tier-1 clinical pathogen surveillance system showed Flu-A predominated in December, Flu-B predominated in January, SARS-CoV-2 peaked in March and August, whereas RSV circulated sporadically throughout the year. Geographic trends were broadly consistent across the seven major regions, although Flu-A detection in December was notably higher in Northeast China (48.1%(111/231)) and East China (36.2%(148/409)), and RSV detection was concentrated in the Northwest and South China from January to March. Data from the tier-2 clinical pathogen surveillance system indicated that Streptococcus pneumoniae, Mycoplasma pneumoniae, rhinovirus, and adenovirus were detected year-round, of these, Streptococcus pneumoniae and rhinovirus showed elevated positive detection rates from August to September, while adenovirus peaked in January. Legionella pneumophila was not detected throughout the year, and other pathogens fluctuated throughout the year without a consistent pattern. The predominant etiologic agents of pediatric pneumonia were Mycoplasma pneumoniae (35.0%(105/300)), rhinovirus (25.7%(77/300)), and adenovirus (17.3%(52/300)), whereas adult pneumonia was mainly caused by Streptococcus pneumoniae (10.5%(29/277)), Staphylococcus aureus (6.9%(19/277)), Mycoplasma pneumoniae (6.9%(19/277)), and Flu-A (6.1%(17/277)). The tier-3 clinical pathogen surveillance system did not identify any emerging respiratory pathogens. Conclusion:Respiratory pathogens in China in 2024 exhibit distinct temporal and spatial distribution patterns and vary among different populations.

Objective To systematically compare the efficacy of different virtual reality(VR)technologies on motor dysfunction in patients with Parkinson's disease(PD)through a network meta-analysis(NMA).Methods Following the PRISMA-NMA guidelines,randomized controlled trials(RCT)that compared the effect of at least two interventions on motor function in patients with PD were searched in PubMed,Embase,Cochrane Li-brary,Web of Science,CNKI,Wanfang data and VIP.The interventions included immersive virtual reality(IVR),non-immersive virtual reality(VRT),augmented reality(AR),treatment as usual(TAU)and active control(AC).The primary outcomes included Unified Parkinson's Disease Rating Scale Part Ⅲ(UPDRS-Ⅲ),Berg Balance Scale(BBS)and Timed Up and Go Test(TUGT).A frequentist-based random-effects model was used to conduct NMA,and the surface under the cumulative ranking curve(SUCRA)was used to rank the interventions.Results A total of 20 RCT involving 890 patients were included.IVR performed best in improving the score of UPDRS-Ⅲ(SUCRA=97.7%)and was significantly superior to TAU(SMD=-0.82,95%CI-1.28 to-0.37).IVR showed the highest probability of being the best option for the score of BBS(SUCRA=85.2%)and was signifi-cantly superior to TAU(SMD=3.94,95%CI 1.08 to 6.80).IVR performed best in the outcome of TUGT(SU-CRA=95.1%)and was significantly superior to VRT(SMD=1.06,95%CI 0.40 to 1.72),AR(SMD=-1.09,95%CI-1.98 to-0.19)and TAU(SMD=-1.38,95%CI-1.95 to-0.82).However,subgroup analysis revealed that the efficacy advantage of IVR was mainly confirmed in short-term(four to six weeks)interventions,while the evidence for long-term efficacy was currently very limited.Conclusion The efficacy of interventions on motor rehabilitation in patients with PD appears to be positively correlated with the technology's level of immersion.As the most immersive technology,IVR is the optimal choice for im-proving overall motor function,balance and mobility in patients with PD.VRT and AR serve as effective adju-vants and are superior to TAU.
