Objective To investigate the value of human papillomavirus(HPV)DNA and HPV E6/E7 mRNA detection in screening for cervical lesions.Methods A total of 619 patients who were screened for cer-vical lesions in West China Second University Hospital from September 2021 to August 2022 were selected as the study objects.The value of HPV DNA and HPV E6/E7 mRNA detection in cervical lesion screening was evaluated based on their pathological results.Results The positive rate of HPV DNA detection was 64.78％(401/619)and that of HPV E6/E7 mRNA detection was 60.74％(376/619)in 619 patients.Cervical lesion screening was mainly conducted in sexually active people aged 30-＜40 years and 40-＜50 years.The posi-tive rates of HPV DNA and HPV E6/E7 mRNA increased with the increase of cervical lesion grade.The sen-sitivity,positive predictive value and negative predictive value of the two methods were higher than those of HPV DNA or HPV E6/E7 mRNA detection.Conclusion The combined detection of the two methods can be used for screening cervical lesions at various pathological stages,which can provide greater guidance value in clinical diagnosis and treatment.

Objective To explore the feasibility and accuracy of neutrophil-to-lymphocyte ratio(NLR)in the prediction of testicular torsion(TT)in children with acute scrotal pain.Methods A retrospective case-control study was performed on 158 pediatric patients with ultrasound suspicion of TT who underwent surgical testicular examination during Jan.2017 and Jan.2024.The patients were divided into TT group and non-TT group.Clinical data and laboratory data at admission were analyzed.Sensitivity and specificity of NLR to TT were determined with the area under the curve(AUC)represented on the receiver operating characteristic(ROC)curves.Results There were with no statistically significant differences in clinical data between the two groups(P＞0.05).The NLR was significantly higher in the TT group than in the non-TT group[(4.82±2.37)vs.(2.85±0.75),P＜0.05].The optimal cut-off value of TT predicted by NLR was 2.07,the AUC was 0.809(95％CI:0.709-0.909),and the sensitivity and specificity were 97.9％and 93.3％,respectively,which were significantly higher than other factors.Conclusion For suspicious ultrasound diagnosis of pediatric acute scrotal pain cases,NLR can be used to predict the possibility of TT and may help to evaluate the urgent surgical treatment in these patients.

Objective To observe the effectiveness of fluorescence labeling-based assay bundle intervention in the prevention and control of multidrug-resistant organism(MDRO)infection.Methods Patients who were detected MDRO in a hospital from January to December 2022 were selected as the research subjects.MDRO monitoring data and implementation status of prevention and control measures were collected.Fluorescence labeling assay was adopted to monitor the cleaning and disinfection effectiveness of the surrounding object surface of the bed units.Based on the bundled prevention and control measures as well as management mode of the pre-intervention group,the post-intervention group implemented enhanced rectification measures for the problems found by the pre-interven-tion group.Changes in relevant indicators between January-June 2022(before intervention)and July-December 2022(after intervention)were compared.Results There were 136 MDRO-infected patients in the pre-intervention group,208 MDRO strains were detected and 10 healthcare-associated infection(HAI)occurred.There were 128 MDRO-infected patients in the post-intervention group,198 MDRO strains were detected and 9 HAI occurred.Af-ter intervention,the total detection rates of methicillin-resistant Staphylococcus aureus(MRSA),carbapenem-re-sistant Acinetobacter baumannii(CRAB),and total MDRO from patients decreased significantly compared to before intervention(all P＜0.05).After intervention,the detection rates of MRSA,carbapenem-resistant Pseudomonas aeruginosa(CRPA),CRAB,and total MDRO from the surrounding object surface were all lower than those before intervention(all P＜0.05).The detection rate of MDRO from surrounding object surface before intervention was 34.52％,which showed a decreased trend after intervention(P＜0.05).The clearance rate of fluorescent labeled markers before intervention was 41.84％,which showed an upward trend after implementing intervention measures(from July to December),and increased to 85.00％at the end of intervention(November-December).The comp-liance rates of issuing isolation medical orders,placing isolation labels,using medical supplies exclusively,and cor-rectly handling medical waste after intervention have all increased compared to before intervention(all P＜0.05).Conclusion Adopting fluorescence labeling-based assay bundle intervention can effectively improve the effectiveness of MDRO infection prevention and control.

Objective To observe the clinical efficacy and safety of nivolumab combined with anlotinib in the treatment of patients with advanced gastric cancer.Methods The patients with advanced gastric cancer were randomly divided into control group and treatment group.The control group received oral apatinib capsules 12 mg,once a day,and discontinued treatment for 7 days after 14 days of maintenance therapy.On the basis of control group,the treatment group received intravenous infusion of 3 mg·kg-1 nivolumab,once every two weeks.Two groups were treated for four cycles with 21 days per cycle.The clinical efficacy,tissue polypeptide specific antigen(TPS),carbohydrate antigen 125(CA125),carcinoembryonic antigen(CEA)and adverse drug reactions were compared between two groups.Results In the treatment group,80 cases were enrolled,and 4 cases dropped out and 76 cases were included in the statistical analysis;in the control group,80 cases were enrolled,and 8 cases dropped out and 72 cases were included in the statistical analysis.After treatment,the total effective rates in the treatment and control group weres 78.95％(60 cases/76 cases)and 52.78％(38 cases/72 cases),and the difference was statistically significant(P＜0.05).After treatment,the levels of CEA in the treatment and control groups were(5.34±1.12)and(7.01±0.97)U·mL-1;the levels of CA125 were(22.65±4.27)and(27.61±5.09)U·mL-1;the levels of TPS were(69.21±11.64)and(53.06±10.57)U·mL-1;these differences were statistically significant(all P＜0.05).The adverse drug reactions of two groups were nausea/diarrhea,leukopenia,thrombocytopenia,abnormal liver function,and hypothyroidism.The total incidences of adverse drug reactions in the treatment and control groups were 40.79％and 37.50％without statistically significant difference(P＞0.05).Conclusion Ramucirumab injection combined with anlotinib capsules is more effective than single-agent anlotinib in the treatment of advanced gastric cancer,without increasing the incidence of adverse drug reactions.

Objective:To analyze the epidemic characteristics of reported tuberculosis incidence in Kashgar from 2015 to 2022, and use the seasonal autoregressive integrated moving average (SARIMA) model to predict the incidence, providing references for the local control of pulmonary tuberculosis.Methods:The reported incidence data of tuberculosis in the Kashgar area of Xinjiang from January 2015 to August 2023 were collected through the"Infectious Disease Monitoring System", a subsystem of the "Chinese Disease Prevention and Control Information System". The epidemic characteristics of reported incidence in this area from 2015 to 2022 were analyzed. Two SARIMA models of monthly reported incidence number and rate were established. The prediction performance of the two models was evaluated using the reported incidence data of tuberculosis from January 2023 to August 2023. The χ2 test was used to analyze population characteristics, and the Cochran-Armitage trend test was used to analyze annual incidence. Results:From 2015 to 2022, 133 972 cases of pulmonary tuberculosis were reported in Kashgar, with a yearly reported incidence rate of 383.64/100 000, showing a rising trend ( TCA=77.03, P<0.001) and then a declining trend ( TCA=176.16, P<0.001). The proportion of pathogenic positive pulmonary tuberculosis had increased yearly ( TCA=132.66, P<0.001). The reported onset time was concentrated from January to June each year, with a peak in April. Yengisar County, Zepu County and Yopurga County had the highest reported incidence rate in Kashgar. The sex ratio of men to women was 1.03∶1, and the reported incidence rate of men was higher than that of women ( χ2=27.04, P<0.001). The reported incidence rate of the group aged 60 years and older was the highest. The patient′s occupation was mainly farmers (84.99%). The average relative errors of the SARIMA ( 1, 1, 2) ( 0, 1, 1) 12 model and SARIMA ( 0, 1, 1)( 0, 1, 1) 12 model in predicting the reported monthly incidence number and rate were 11.67% and -9.81%, respectively. Both models had good prediction accuracy (MAPE=33.55%, MAPE=38.22%). Conclusion:The average reported incidence rate of pulmonary tuberculosis in the Kashgar area shows a rising trend first and then a declining trend. The patients are mainly men and farmers, and attention should be paid to the prevention and control of tuberculosis among the elderly in winter and spring. The SARIMA ( 1, 1, 2) ( 0, 1, 1) 12 model and SARIMA ( 0, 1, 1)( 0, 1, 1) 12 model can fit the trend of reported tuberculosis incidence in the Kashgar area well and have good predictive performance.

Objective: The purpose of this study was to assess the safety and efficacy of a second allogeneic hematopoietic stem cell transplantation (allo-HSCT) with reduced-intensity conditioning (RIC) in patients with hematological malignancies who had relapsed after the first allo-HSCT. Methods: Between April 2018 and June 2021, 44 patients with hematological malignancies (B-ALL 23, T-ALL/T-LBL 4, AML15, and MDS 2) were enrolled and retrospectively examined. Unrelated donors (n=12) or haploidentical donors (n=32) were used. Donors were replaced in all patients for the second allo-HSCT. Hematological and immunological germline predisposition genes and hematopoietic and immune function tests were used to select the best-related donor. Total body irradiation (TBI) /fludarabine (FLU) -based (n=38), busulfan (BU) /FLU-based (n=4), total marrow irradiation (TMI) /FLU-based (n=1), and BU/cladribine-based (n=1) were the RIC regimens used. For graft versus host disease (GVHD) prevention, cyclosporine, mycophenolate mofetil, short-term methotrexate, and ATG were used. Eighteen (40.9%) of 44 patients with gene variations for which targeted medications are available underwent post-transplant maintenance therapy. Results: The median age was 25 years old (range: 7-55). The median interval between the first and second HSCT was 19.5 months (range: 6-77). Before the second allo-HSCT, 33 (75%) of the patients were in complete remission (CR), whereas 11 (25%) were not. All patients had long-term engraftment. The grade Ⅱ-Ⅳ GVHD and severe acute GVHD rates were 20.5% and 9.1%, respectively. Chronic GVHD was found in 20.5% of limited patterns and 22.7% of severe patterns. CMV and EBV reactivation rates were 29.5% and 6.8%, respectively. Hemorrhage cystitis occurred in 15.9% of cases, grade Ⅰ or Ⅱ. The 1-yr disease-free survival (DFS), overall survival (OS), and cumulative recurrence incidence (RI) rates of all patients were 72.5% (95% CI, 54.5%-84.3%), 80.6% (95% CI, 63.4%-90.3%), and 25.1% (95% CI, 13.7%-43.2%), respectively, with a median follow-up of 14 (2-39) months. There were eight deaths (seven relapses and one infection). The rate of non-relapse mortality (NRM) was only 2.3%. The CR patients' 1-yr RI rate was significantly lower than the NR patients (16.8% vs 48.1%, P=0.026). The DFS rate in CR patients was greater than in NR patients, although there was no statistical difference (79.9% vs 51.9%, P=0.072). Univariate analysis revealed that CR before the second allo-HSCT was an important prognostic factor. Conclusion: With our RIC regimens, donor change, and post-transplant maintenance therapy, the second allo-HSCT in relapsed hematological malignancies after the first allo-HSCT is a safe and effective treatment with high OS and DFS and low NRM and relapse rate. The most important factor influencing the prognosis of the second allo-HSCT is the patient's illness condition before the transplant.

Objective: To compare the prognosis of mildly or severely symptomatic patients with obstructive hypertrophic cardiomyopathy (OHCM) who underwent alcohol septal ablation (ASA). Methods: This retrospective study cohort consisted of patients with OHCM who received ASA treatment in Beijing Anzhen Hospital, Capital Medical University from March 2001 to August 2021. These patients were divided into mildly and severely symptomatic groups according to the severity of clinical symptoms. Long-term follow-up was conducted, and the following data were collected: duration of follow-up, postoperatire treatment, New York Heart Association (NYHA) classification, arrhythmia events and pacemaker implantation, echocardiographic parameters, and cause of death. Overall survival and survival free from OHCM-related death were observed, and the improvement of clinical symptoms and resting left ventricular outflow tract gradient (LVOTG) and the incidence of new-onset atrial fibrillation were evaluated. The Kaplan-Meier method and log-rank test were used to determine and compare the cumulative survival rates of the different groups. Cox regression analysis models were used to determine predictors of clinical events. Results: A total of 189 OHCM patients were included in this study, including 68 in the mildly symptomatic group and 121 in the severely symptomatic group. The median follow-up of the study was 6.0 (2.7, 10.6) years. There was no statistical difference in overall survival between the mildly symptomatic group (5-year and 10-year overall survival were 97.0% and 94.4%, respectively) and the severely symptomatic group (5-year and 10-year overall survival were 94.2% and 83.9%, respectively, P=0.405); there was also no statistical difference in survival free from OHCM-related death between the mildly symptomatic group (5-year and 10-year survival free from HCM-related death were 97.0% and 94.4%, respectively) and the severely symptomatic group (5-year and 10-year survival free from HCM-related death were 95.2% and 92.6%, respectively, P=0.846). In the mildly symptomatic group, NYHA classification was improved after ASA (P<0.001), among which 37 patients (54.4%) were in NYHA class Ⅰ, and the resting left ventricular outflow tract gradient (LVOTG) decreased from 67.6 (42.7, 90.1) mmHg (1 mmHg=0.133 kPa) to 24.4 (11.7, 35.6) mmHg (P<0.001). In severely symptomatic group, NYHA classification was also improved post ASA (P<0.001), among which 96 patients (79.3%) improved by at least one NYHA classification, and the resting LVOTG decreased from 69.6 (38.4, 96.1) mmHg to 19.0 (10.6, 39.8) mmHg (P<0.001). The incidence of new-onset atrial fibrillation was similar between the mildly and severely symptomatic groups (10.2% vs. 13.3%, P=0.565). Cox multivariate regression analysis showed that age was an independent predictor of all-cause mortality in OHCM patients post ASA (HR=1.068, 95%CI 1.002-1.139, P=0.042). Conclusions: Among patients with OHCM treated with ASA, overall survival and survival free from HCM-related death were similar between mildly symptomatic group and severely symptomatic group. ASA therapy can effectively relieve resting LVOTG and improve clinical symptoms in mildly or severely symptomatic patients with OHCM. Age was an independent predictor of all-cause mortality in OHCM patients post ASA.
