Objective:To investigate the impact of Wenyang Ligong Decoction on pregnancy outcomes after transcervical resection of adhesions (TCRA) in patients with intrauterine adhesions (IUA).Methods:A retrospective cohort study was conducted to collect clinical data from 151 patients with IUA who underwent TCRA in the Reproductive Medicine Department of the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine between January 2020 and January 2023. Patients were divided into a Traditional Chinese medicine (TCM) group (79 patients) and a control group (72 patients) based on whether they received Wenyang Ligong Decoction after TCRA. The TCM group received estrogen and progesterone sequential therapy post-surgery, combined with Wenyang Ligong Decoction for 2-3 menstrual cycles. The control only received sequential treatment with estrogen and progesterone.Pregnancy outcomes one year after surgery were compared between the two groups. After adjusting for confounding factors using multivariate Cox regression analysis, the effect of Wenyang Ligong Decoction on pregnancy outcomes after TCRA in patients with IUA was observed.Results:The live birth rate [54.43%　(43/79)], the ongoing pregnancy rate [56.96% (45/79)], and the clinical pregnancy rate [52.03% (49/79)] were higher in the TCM group than in the control [26.39% (19/72), P<0.001; 30.56% (22/72), P=0.001;37.50% (27/72), P=0.003], with statistically significant differences. There were no statistically significant differences in early abortion rate and late abortion rate between the TCM group and the control (all P>0.05). According to the stratified analysis by preparation methods, in the natural conception group, the live birth rate [60.78% (31/51)], the ongoing pregnancy rate [62.75% (32/51)], and the clinical pregnancy rate [68.63% (35/51)] in the TCM group were significantly higher than those in control group [21.43% (12/56), P<0.001; 26.79% (15/56), P<0.001; 33.93% (19/56), P<0.001]; there were no statistically significant differences in early miscarriage rate and late miscarriage rate between the two groups (both P>0.05). In the assisted reproductive technology group, there were no statistically significant differences in live birth rate, ongoing pregnancy rate, clinical pregnancy rate, early miscarriage rate, and late miscarriage rate between the two groups (all P>0.05). According to the stratified analysis by age, in the <35-year-old patients, the live birth rate [66.00% (33/50)], the ongoing pregnancy rate [70.00% (35/50)], and the clinical pregnancy rate [74.00% (37/50)] in the TCM group were significantly higher than those in control group [41.30% (19/46), P=0.015; 47.83% (22/46), P=0.027; 54.35% (25/46), P=0.044]; there were no statistically significant differences in early miscarriage rate and late miscarriage rate between the two groups (both P>0.05). In the ≥35-year-old patients, the live birth rate [34.48% (10/29)], the ongoing pregnancy rate [34.48% (10/29)], and the clinical pregnancy rate [41.38% (12/29)] in the TCM group were significantly higher than those in control group [0%, P=0.001; 0%, P=0.001; 7.69% (2/26), P=0.004]; there were no statistically significant differences in early miscarriage rate and late miscarriage rate between the two groups (both P>0.05).Univariate Cox regression analysis showed that age, number of previous uterine cavity interventions, IUA score, degree of IUA, and endometrial thickness after TCRA were independent risk factors for live births, and age, IUA score, degree of IUA, intima thickness after TCRA, and treatment group were the influencing factors of persistent pregnancy (all P<0.05). After adjusting for confounding factors, multivariate Cox regression analysis showed that Wenyang Ligong Decoction significantly improved the live birth rate ( HR=3.19, 95% CI: 1.77-8.11, P=0.001) and the rate of continuous pregnancy ( HR=3.66, 95% CI: 1.80-7.48, P<0.001) in patients with IUA. Conclusion:Wenyang Ligong Decoction can significantly improve pregnancy outcomes after TCRA in patients with IUA.

Objective To explore the role of meibomian gland massage combined with the ROY adaptation model in nursing of xerophthalmia.Methods The medical records of 286 patients with xerophthalmia admitted from March 2022 to October 2023 were retrospectively included.The patients were divided into conventional group(141 cases)and combined group(145 cases)according to dif-ferent intervention methods.Both groups received optimized pulsed light therapy.The conventional group received meibomian gland massage and routine nursing for xerophthalmia,while the combined group received additional nursing based on the ROY adaptation model.The improvement effects on subjective symptoms(dryness,foreign body sensation,fatigue,photophobia,and burning sensation)as well as psychological status[Symptom Checklist-90(SCL-90)],self-efficacy[General Self-Effica-cy Scale(GSES)],ocular surface status[Ocular Surface Disease Index(OSDI)],and quality of life[the scale of quality of life for diseases with visual impairment(SQOL-DVI)]before and after inter-vention were compared between the two groups.Results The disappearance time of dryness,foreign body sensation,fatigue,photophobia,and burning sensation were shorter in the combined group than those in the conventional group(P＜0.05).After the intervention,the scores of all dimensions and the total score of SCL-90 decreased in both groups compared with those before the intervention,and the scores in the combined group were lower than those in the conventional group(P＜0.05).After the intervention,the scores for facing problems,coping with problems,and the total score increased in both groups compared with those before the intervention,and the scores in the combined group were higher than those in the conventional group(P＜0.05).After the intervention,the scores for ocular symp-toms,visual function,environmental triggers factors,and the total score decreased in both groups compared with those before the intervention,and the scores in the combined group were lower than those in the conventional group(P＜0.05).After the intervention,the scores for general health status,symptoms and visual function,social activities,mental health,and the total score increased in both groups compared with those before the intervention,and the scores in the combined group were higher than those in the conventional group(P＜0.05).Conclusion Meibomian gland mas-sage combined with nursing based on the ROY adaptation model can improve dry eye symptoms,ad-just the ocular surface status,enhance self-efficacy,and improve the quality of life of patients.

To analyze the transmission characteristics of newly reported HIV-infected students aged ≥18 years in Nanjing City from 2016 to 2022 and provide evidence for AIDS publicity and intervention among young students. The pol region sequences of newly reported HIV-infected students and non-student HIV-infected individuals in Nanjing City from 2016 to 2022 were collected, and the BLAST tool was used to search the published global non-Nanjing reported HIV infection sequences in the LANL HIV database. The basic molecular transmission network and regional molecular transmission network were constructed using the HIV-TRACE in a pairwise genetic distance threshold of 1.0%. 332 sequences of infected students aged≥18 years in Nanjing City, 1 904 sequences of non-student-infected individuals in Nanjing City and 1 698 non-Nanjing-infected individuals were obtained. Among the 332 infected students, the main route of infection was homosexual (96.39%), and the subtypes were CRF01_AE (37.95%), CRF07_BC (37.65%) and CRF105_0107 (10.24%). There were 890 sequences in the regional molecular transmission network, of which 21.80% were infected students in Nanjing City, 39.89% were non-student-infected individuals in Nanjing City, and 38.31% were non-Nanjing-infected individuals. In the CRF105_0107 transmission cluster, non-student-infected individuals from Nanjing accounted for 66.95% (81/121), while in the CRF07_BC transmission cluster, non-Nanjing-infected individuals accounted for 56.66% (200/353). There were 1 644 edges connected to infected students within the regional molecular transmission network, with local transmission accounting for 64.72% and regional transmission accounting for 35.28%. Regional transmission was mainly in Guangdong Province (19.83%) and other cities in Jiangsu Province (4.50%). The HIV-1 subtypes of newly reported HIV-infected students aged≥18 years in Nanjing City are mainly CRF01_AE, CRF07_BC and CRF105_0107, with local transmission as the main transmission characteristics. There is transmission between students and non-students.

Objective:To explore the dynamic trends of family caregivers' supportive care needs and family resilience in enterostomy patients and to analyze the reciprocal predictive relationship between the two.Methods:This study was longitudinal. Convenience sampling was used to select 370 family primary caregivers of colorectal cancer patients with enterostomy in the Affiliated Cancer Hospital of Xinjiang Medical University and the Xinjiang Bazhou People's Hospital from December 2023 to September 2024 as study subjects. Patients were surveyed using the General Information Questionnaire, Family Hardiness Index, and Supportive Care Needs Survey-Partners and Caregivers at four time points of admission (T1), discharge (T2), one month after surgery (T3), and three months after surgery (T4). Spearman correlation was used to analyze the correlation between supportive care needs of family caregivers of enterostomy patients and family resilience at different time points, and a cross-lagged model was constructed to explore the predictive role of supportive care needs on family resilience.Results:A total of 370 questionnaires were distributed and 336 valid questionnaires were finally recovered, with a valid recovery rate of 90.81% (336/370). Supportive care needs of family caregivers and family resilience of 336 family caregivers of enterostomy patients showed an increasing and then decreasing trend during hospitalization to three months after surgery ( P<0.05). Spearman correlation analysis showed that supportive care needs of family caregivers of enterostomy patients were negatively correlated with family resilience ( P<0.01). Cross-lagged model showed that supportive care needs of family caregivers of enterostomy patients at T1, T2, and T3 negatively predicted family resilience in the next period (β=-0.308, -0.204, and -0.243; all P<0.05), but not vice versa. Conclusions:Family caregiver supportive care needs and family resilience of enterostomy patients showed a dynamic trend of increasing and then decreasing during the hospitalization to three months postoperatively, and family caregiver supportive care needs are able to influence subsequent family resilience. Healthcare professionals should assess the supportive care needs of family caregivers and take targeted measures to meet their supportive care needs in a timely manner, in order to enhance the family resilience, create a good family environment for patients' recovery, and improve the quality of life of patients and their family caregivers.

Objective To analyze the genomic characteristics of Klebsiella pneumoniae carrying blaNDM-1 and Atlanta subterranean carry-ing blaIMP-4 isolated from the stool sample of the same patient and elucidate their resistance mechanisms.Methods The minimum in-hibitory concentrations(MIC)of the isolated strains were detected by the micro-broth dilution method.The NG-Test CARBA-5 was used to detect the phenotype of carbapenemases.The genomic characteristics of the strains were analyzed by the whole genome sequen-cing(WGS)and bioinformatics analysis.Results The isolated Klebsiella pneumoniae was resistant to most antibiotics.Atlanta subter-ranean was resistant to meropenem and ertapenem,but sensitive to imipenem.The two strains were susceptible to polymyxin,tigecy-cline,amikacin,ciprofloxacin,and aztreonam.The WGS analysis showed that Klebsiella pneumoniae belonged to ST1040 type and car-ried 8 resistance genes,including blaNDM-1,aac(6')-Ib-cr.v2,aadA16,aadA2,qnrS1,arr-3,sul1 and dfrA27,and 4 plasmid repli-cons such as lncR,lncU,lncFIA(Hl1)and lncFIB(K).Atlanta subterranean carried two resistance genes(blaIMP-4 and qnrS1)and 1 plasmid replicon(lncN).The analysis results of virulence factors showed that Klebsiella pneumoniae carried virulence factors such as fimbrium,capsule,and siderophore.Atlanta subterranean carried virulence factors such as fimbrium,flagella,lipopolysaccharides,and endotoxins.Conclusion The Atlanta subterranean producing blaIMP-4 enzyme and Klebsiella pneumoniae producing blaNDM-1 enzyme are isolated from the stool sample of the same patient,and their genomic characteristics are analyzed.The emergence of new carbapen-em-resistant strains poses a huge challenge to clinical treatment and infection prevention and control.The screening and detection of carbapenemase genes should be strengthened.

Objective:To explore the efficacy and its related factors of rituximab (RTX) in the treatment of children with frequently relapsing nephrotic syndrome/steroid-dependent nephrotic syndrome (FRNS/SDNS).Methods:It was a single-center retrospective study. The clinical data of FRNS/SDNS children first treated with RTX in the First Affiliated Hospital of Sun Yat-sen University from November 1, 2016 to September 1, 2023 were collected. The number of relapse within 1 year before and after RTX treatment, the time to first relapse after RTX treatment, and the time to B-cell reconstitution were analyzed. At the first treatment, a single dose of RTX was given at 375 mg/m 2, with a maximum dose of 500 mg, once a week, for 1 to 4 doses. The count of CD19 + lymphocytes in the peripheral blood of the children was continuously monitored. If B-cell reconstruction was performed, the decision on whether to proceed to the next course of RTX treatment was made based on clinical manifestations. Kaplan-Meier method was used to analyze relapse-free survival rate after receiving RTX. Cox proportional hazards regression model was used to analyze the related factors of relapse after RTX treatment. Results:A total of 98 FRNS/SDNS children receiving RTX treatment were enrolled, including 75 males (76.5%). The age at onset was 4.0 (1.9, 7.1) years and age of receiving RTX was 11.3 (8.5, 13.5) years. There were 90 children (91.8%) achieving complete remission, while 8 patients (8.2%) did not respond to RTX treatment, and 3 patients (3.1%) progressed to end-stage kidney disease after receiving RTX. The relapse-free survival rates at 6 months and 1 year after RTX treatment were 83.3% (75/90) and 57.9% (22/38), respectively. The frequency of relapse 1 year after RTX treatment decreased compared to 1 year before RTX treatment ( Z=-7.398, P<0.001). Compared with children without relapse during the period of B-cell depletion, relapsed children had a higher number of relapse within one year after RTX treatment ( Z=5.246, P<0.001). The time to first relapse after RTX treatment was 8.3 (4.6, 13.9) months in 51 relapse patients. Compared with children receiving 1 dose of RTX in the first course, those receiving 2 or more doses had a longer time to the first relapse ( Z=2.983, P=0.003). There was no statistically significant difference in time to the first relapse between children who received mycophenolate mofetil therapy after RTX treatment and those who didn't ( P>0.05). The reconstruction time of B cells after the first course of RTX was 6.9 (5.3, 9.0) months. Compared to children receiving one dose of RTX in the first course, those receiving two or more doses had a longer B-cell reconstitution time ( Z=2.739, P=0.006). There was no statistically significant difference in B-cell reconstitution time between children who received mycophenolate mofetil therapy after RTX treatment and those who didn't ( P>0.05). Univariate Cox regression analysis showed that recurrence after calcineurin inhibitor (CNI) treatment before RTX treatment and the number of recurrence in one year before RTX treatment were correlated factors of recurrence after RTX treatment (both P<0.05). Multivariate Cox regression analysis showed that recurrence after CNI treatment before RTX treatment was an independent correlated factor of relapse after RTX therapy ( HR=3.496, 95% CI 1.245-9.818, P=0.018). Infusion reactions occurred in 10 patients (10.2%) and infections were observed in 24 patients (24.5%) during B cell depletion. No serious adverse events occurred. Conclusions:RTX is well tolerated and effective in treating FRNS/SDNS. Recurrence after CNI treatment before RTX treatment may be an independent related factor of relapse after RTX treatment.
