ObjectiveTo analyze the influencing factors for recurrence in successfully treated pulmonary tuberculosis patients with isoniazid-resistant and rifampicin-sensitive in Shaoxing City, Zhejiang Province. MethodsData on general demographic information, treatment information and drug susceptibility test results for pulmonary tuberculosis patients admitted to the designated tuberculosis medical institutions and registered in the tuberculosis information management system was collected in Shaoxing City from January 2011 to August 2024. A total of 428 patients with isoniazid resistance (including isoniazid single resistance and multiple resistance) but who were successfully treated were included in the study. Information for the recurrence after successful treatment of the patients was analyzed. The Cox proportional hazards models were used to analyze the influencing factors of recurrence in patients. ResultsAmong the 428 successfully treated patients included in the study, 31 cases (accounting for 7.24%) had recurrence by the end of the observation period, with a recurrence rate density of 1.31 per 100 person-years and a median recurrence time of 0.99 (0.08, 8.27) years. Among the relapsed population, 51.61% of the patients relapsed within one year after successful treatment. 77.42% of the patients relapsed within two years after successful treatment. Multivariate Cox regression analysis showed that when isoniazid resistance was discovered, the diagnosis classification of relapse (HR=4.115, 95%CI: 1.734‒9.767) and positive 0-month sequence smear (HR=4.457, 95%CI: 1.053‒18.866) were risk factors for recurrence after successful treatment in patients. ConclusionRegular follow-up should be strengthened for at least two years after the successful treatment of isoniazid-resistant pulmonary tuberculosis patients. Special attention should be paid to the treatment effect and regular re-examination and monitoring after the end of the treatment course of isoniazid-resistant pulmonary tuberculosis patients who have been re-treated and were sputum smear positive at baseline, so as to prevent recurrence and disease progression in high-risk populations.

Objective: To investigate the status of tuberculin skin test (TST) results and the influencing factors among student close contacts with pulmonary tuberculosis, so as to provide the evidence for developing prevention and control strategies for pulmonary tuberculosis among students. Methods: The students aged 15 years and above who had close contact with pulmonary tuberculosis cases in Yuecheng District, Shaoxing City, Zhejiang Province, from October 2016 to December 2023 were recruited and investigated using questionnaires and TST to collect demographic information, contact history, and TST results. The influencing factors for TST positivity among student close contacts with pulmonary tuberculosis were analyzed using a multivariable logistic regression model. Results: A total of 5 507 student close contacts were investigated, including 2 982 males and 2 525 females, with a male-to-female ratio of 1.18∶1. The mean age was (19.10±1.71) years. Among them, 397 (7.21%) were technical secondary school students, 766 (13.91%) were senior high school students, 2 556 (46.41%) were junior college students, and 1 788 (32.47%) were college students or above. A total of 958 students tested positive for TST, with a positivity rate of 17.40%. The rates of general positivity, moderate positivity, and strong positivity were 10.53%, 4.98% and 1.89%, respectively. Multivariable logistic regression analysis showed that senior high school students (OR=1.473, 95%CI: 1.009-2.152) and junior college students (OR=1.467, 95%CI: 1.074-2.005), as well as those with an exposure-to-screening interval of ≥46 days (46-<61 days, OR=2.043, 95%CI: 1.478-2.826; ≥61 days, OR=1.291, 95%CI: 1.018-1.637) had a higher risk of TST positivity. Female student close contacts had a lower risk of TST positivity (OR=0.753, 95%CI: 0.649-0.873). Conclusion The TST positivity rate was relatively high, and gender, school type, and exposure-to-screening interval were influencing factors for TST positivity among student close contacts with pulmonary tuberculosis.

Objective:To investigate the effects and molecular mechanisms of Wilms tumor 1-associated proteins(WTAP)on the cell biological properties of esophageal squamous cell carcinoma(ESCC)cells.Methods:31 pairs of ESCC tissues and their paired paracancerous tissues that were surgically resected at the Second Clinical Medical College of Chuanbei Medical College between September 2019 and April 2021 were collected.The esophageal cancer cells KYSE30,KYSE410,KYSE150,KYSE510,TE-1,and normal human esophageal epithelial cells HET-1A were routinely cultured.Transfection reagents were used to transfect si-NC,si-WTAP#1 and si-WTAP#2 nucleic acids into KYSE150 and KYSE510 cells.The cells were divided into si-NC,si-WTAP#1 and si-WTAP#2 groups.The expressions of WTAP and MAP3K9 mRNA were detected in the cells of each group by qPCR assay.CCK-8 assay,clone formation assay,and scratch healing assay,Transwell assay were employed to detect the effects of knockdown of WTAP expression on ESCC cell proliferation,migration,invasion and apoptosis.WB assay was used to detect the expressions of WTAP,MAP3K9,EMT and MAPK pathway-related proteins in ESCC cells of each group knocked down of WTAP;immunohistochemistry to detect the expression of WTAP proteins in ESCC tissues,immunoprecipitation of methylated RNA(MeRIP)-qPCR assay to detect the level of MAP3K9 m6A in ESCC cells,actinomycin D assay to detect the stability of mRNA of MAP3K9,and database data to analyze the expression,target genes,functional enrichment,and interacting RNA of WTAP.Results:WTAP was highly expressed in ESCC tissues and cells(P<0.05 or P<0.01 or P<0.001)and correlated with the degree of differentiation(P<0.01);the expression of WTAP mRNA and its protein were successfully knocked down in KYSE150 and KYSE510 cells(P<0.01 or P<0.001);the knockdown of WTAP significantly inhibited the proliferation,migration and invasion of KYSE150 and KYSE510 cells(P<0.05 or P<0.01 or P<0.001),and promoted the apoptosis of KYSE150 and KYSE510 cells(P<0.05 or P<0.01).Knockdown of WTAP resulted in a significant decrease in the m6A level of MAP3K9(P<0.05),and its mRNA expression level and mRNA stability were both significantly reduced(P<0.05).Database data analysis showed that WTAP target genes clustered in the MAPK signaling pathway;the expression levels of MAP3K9,p-ERK,N-cadherin,and MMP9 were significantly reduced(P<0.05 or P<0.01),and the expression level of E-cadherin was significantly elevated(P<0.05 or P<0.01)in the KYSE150 and KYSE510 cells after knockdown of WTAP.Conclusions:WTAP is highly expressed in ESCC tissues and cells and correlates with their differentiation.It promotes the stability of MAP3K9 mRNA through m6A modification,activates the MAPK pathway and thus promotes the malignant biological behaviors of ESCC cells.

Objective To develop and validate a"quick self-assessment questionnaire for cochlear implant out-come(QSACI)".Methods A research team,composed of audiologists,otolaryngologists,data analysis experts,and cochlear implant(CI)recipients,was formed to establish objectives,research subject criteria,and framework of the QSACI.An item pool was creaed through literature review and brainstorming.Question items were evaluated and screened,and the framework and answer options of the questionnaire were established.The comprehensibility,etc.,was analyzed and refined through pilot test,interviews,and expert consultation,leading to the development of the final version.A total of 39 post-lingually deafened adults with known stable outcomes completed the question-naire.The split-half and test-retest reliabilty of the questionnaire was analyzed,and the validity was quantitatively analyzed by comparing scores with the categories of auditory performance(CAP)scores.Results The initial item pool of the questionnaire had 18 items,and the final questionnaire consisted of 12 questions in four dimensions:com-munication status,audiological status,medical factors,and other factors.The average score of 39 recipients was 88.81±6.17 and CAP was 6.19±0.94.The questionnaire showed good reliability and validity,with a Cronbach's alpha coefficient of 0.71 and a test-retest reliability of 0.824(P＜0.05).The criterion-related validity,assessed by the correlation between the self-assessment questionnaire scores and CAP scores,showed a significant moderate pos-itive correlation(r=0.512,P＜0.05).The correlation coefficient between self-assessment and professional assess-ment was 0.720(P＜0.05),indicating a significant correlation.The area under the receiver operating characterstic(ROC)curve was 0.82(P＜0.05),the cutoff values corresponding to the maximal Youden index were 82.5 and 88.6,therefore score of 85 was taken as the median threshold score of judgement.Conclusion The QSACI reflects the post-imlplant outcomes,and it can serve as a tool for people with postlingually deafness and their families to un-derstand the eligbility of CI and the expected outcomes,helping to establish realistic expectations before CI surgery.

Objective:To explore the application value of E-learning+mind mapping in nursing internship teaching in the department of neurology.Methods:A total of 215 nursing students admitted for internships in February 2021 were selected as research subjects. They were randomly divided into two groups. The observation group received teaching method combining E-learning and mind mapping, while the control group received conventional teaching method. The two groups of nursing students were compared in terms of internship assessment results, learning engagement (learning engagement scale), clinical thinking ability (clinical thinking ability evaluation scale), and student self-recognition. SPSS 20.0 was used for t test and chi-square test. Results:After 1 month of internship, the scores of theories and practical operation were significantly higher in the observation group than in the control group [(90.05±3.02) vs. (85.29±4.17) and (81.33±5.26) vs. (78.62±4.69), all P<0.05]. The score of learning engagement scale, score of clinical thinking ability evaluation scale, and self-recognition rate were significantly higher in the observation group than in the control group (all P<0.05). Conclusions:E-learning+mind mapping can significantly enhance the learning efficiency of intern nursing students in the department of neurology and improve their clinical nursing thinking ability, making it worthy of widespread application.

OBJECTIVE To observe the efficacy and safety of hydromorphone in patient-controlled intravenous analgesia(PCIA)after uvulopalatopharyngoplasty.METHODS A total of 90 patients who received uvulopalatopharyngoplasty in Central Theater General Hospital from January 2022 to June 2023 were selected and divided into three groups(n=30 in each group)by using random number table method.Control group was given sufentanil 2.0 μg/kg,group A was given hydromorphone 0.20 mg/kg and group B was given hydromorphone 0.30 mg/kg.The analgesic parameters of three groups were background infusion rate of 1.2 ml/h,PCA amount of 2 ml,and lock-up time of 10 min.VAS score and Ramsay sedation score at 2 h,6 h,12 h,24 h and 48 h after surgery were recorded,as well as the number of compressions within 48 h after surgery,and the incidence of adverse reactions were analyzed.RESULTS There were no significant differences in intraoperative blood loss,operation time and intraoperative urine volume among the three groups(P>0.05).VAS score in group A and group B at 2 h(2.0±0.3,2.2±0.4),6 h(1.8±0.4,1.9±0.4),12 h(1.8±0.4,1.7±0.4),24 h(1.6±0.3,1.5±0.4)and 48 h(1.1±0.3,1.2±0.4)were significantly lower than those in control group(2.8±0.5,2.3±0.5,2.1±0.4,2.0±0.5,1.7±0.5)(P<0.05),but there was no significant difference between group A and group B(P>0.05).The Ramsay score of group A and group B at 2 h,6 h,12 h,24 h,and 48 h after operation was significantly lower than that of the control group(P<0.05).There was no significant difference in Ramsay score between group A and group B(P>0.05).The total number of compressions and effective number of compressions in group A and group B at 12 h,24 h and 48 h after surgery were lower than those in control group(P<0.05),but there was no significant difference between group A and group B(P>0.05).The incidence of total adverse reactions in group B was higher than that in group A and control group(P<0.05).There was no significant difference in the incidence of total adverse reactions between group A and control group(P<0.05).CONCLUSION Hydromorphone can effectively be used for postoperative self-controlled analgesia in patients with uvulopalatopharyngoplasty,and the efficacy is better than sufentanil,but the dose of 0.20 mg/kg hydromorphone has better safety than that of 0.3 mg/kg hydromorphone.
