Objective To compare the efficacy of common clinical interventions in the treatment of cervical high-risk (HR) HPV infection based on Bayesian network meta-analysis. Methods Randomized controlled trials (RCTs) about common clinical interventions for cervical HR-HPV infection were searched in PubMed, Web of Science, Embase, The Cochrane Library, CBM, CNKI, Wanfang Data, and VIP databases from inception to July 31, 2021 using specific inclusion and exclusion criteria. The quality of the included studies was evaluated in accordance with the Cochrane systematic review manual. Meta-analysis was performed with Stata16 and RevMan5.3 software. Results Seventy-three RCTs were included, involving 3642 patients and eight treatment methods. Network meta-analysis showed that in the three months after treatment, the negative conversion rate was in the order: PTL > anti-HPV BPD > ALA-PDT > Nr-CWS > BFKS > CSJZS > rhIFNα-2b > FUO. In the six months after treatment, the negative conversion rate was in the order: Nr-CWS > ALA-PDT > PTL > anti-HPV BPD > BFKS > rhIFNα-2b > FUO > CSJZS. In the nine months after treatment, the negative conversion rate was in the order: PTL > ALA-PDT > BFKS > anti-HPV BPD > rhIFNα-2b > FUO. IN the 12 months after treatment, the negative conversion rate was in the order: Nr-CWS > ALA-PDT > anti-HPV BPD > PTL > BFKS > rhIFNα-2b > FUO > CSJZS. Conclusion In terms of HPV negative conversion rate, Nr-CWS and PTL are more effective and currently ideal compared with the other treatments. Owing to the quality of the evidence, the above conclusions must be confirmed by future high-quality studies.

Objective:To identify the transmission relationship between HIV infection cases the non-marital non-commercial heterosexual contact in Zhejiang Province.Methods:When HIV positive was informed during January 2020 to January 2022, the staff conducted an epidemiological investigation to collect cases information on sociodemographic characteristics, mobility information, past HIV testing history, high-risk sexual behaviors, sexual partners, and etcetera. At the same time, 6-8 ml of blood from the new diagnosis of people infected with HIV before antiviral treatment was collected to separate the bleeding plasma. pol gene was amplified by nucleic acid extraction and PCR, sequenced by Sequencer 5.0 software, and Cytoscape 3.6.0 software was used to draw HIV molecular transmission network. Results:From January 2020 to January 2022, 88 HIV infected individuals were found in Pujiang County, of which 74 were transmitted through heterosexual transmission, of which 31 were infected through non-marital non-commercial heterosexual contact. Preliminary case studies have found that three female cases have engaged in unprotected non-marital non-commercial heterosexual contact with one male case. Among the 4 infected individuals, 2 of their spouses tested positive for HIV antibodies. Molecular transmission network monitoring was carried out on 65 newly diagnosed cases of heterosexual transmission with acquired sequences, forming 9 transmission clusters. The largest cluster contained 10 cases. A total of 11 HIV-infected individuals were involved in this HIV cluster epidemic. They were 3 males and 8 females, all over 50 years old and were farmers or rural housewives. They were traced to 7 sexual partners (6 negatives of HIV, 1 undetected). Among the 18 respondents' sexual social network relationships, there were 6 couples, 8 permanent partners, and 3 temporary partners. Among 11 HIV infected individuals, there were 9 cases of non-marital non-commercial heterosexual transmission and 2 cases of intramarital transmission. The epidemiological association between 7 non-married non-commercial heterosexual partners and case 2 (56-year-old male farmer), 3 cases confirmed by epidemiological investigation and molecular transmission cluster results, 3 cases confirmed by molecular transmission cluster and epidemiological investigation results, and 1 case confirmed by epidemiological investigation results.Conclusions:The transmission mode of this cluster epidemic was to spread HIV through heterosexual sex with a male case as the core, then cause the transmission within marriage and between fixed sexual partners. The combination of epidemiological investigation and molecular transmission network traceability survey supports the conclusion of this study.

ObjectiveTo investigate the current situation of personality traits and job satisfaction of pediatric therapists in Jiangsu province, and to explore the correlation between them and the related factors of job satisfaction. MethodsFrom June, 2021 to February, 2022, random cluster sampling method was adopted after field investigating several pediatric hospitals and institutions in Jiangsu. Online questionnaires were sent out to pediatric therapists in different settings in eleven cities in Jiangsu. The questionnaires included Minnesota Satisfaction Questionnaire (MSQ), Eysenck Personality Questionnaire-Revised Short Scale for Chinese (EPQ-RSC) and self-made scale of demographic characteristics and working status. ResultsAll of the questionaires were taken back, in which 165 were valid (83.33%). Among the three dimensions of psychoticism, extraversion and neuroticism, the intermediate type accounted for 66.06%, 38.79% and 40.00%, respectively. The overall satisfaction of job was (3.80±0.55), the internal satisfaction was (3.88±0.53), and the external satisfaction was (3.59±0.69). There was significant difference in the satisfaction among different types of work institution, monthly incomes, levels of parental support and neuroticism (P < 0.05). Multiple linear regression showed that the internal satisfaction and overall satisfaction were related with neuroticism, monthly income and parental support (P < 0.05), while external satisfaction was related with the neuroticism and parental support (P < 0.05). The level of neuroticism was negatively correlated with the internal satisfaction, the external satisfaction and overall satisfaction (|r| > 0.337, P < 0.001), and the level of extraversion was postively correlated with the external satisfaction (r = 0.155, P < 0.05). ConclusionThe job satisfaction of pediatric therapists is fine in Jiangsu, and is ralated with the level of neuroticism, the monthly income and the level of parental support. The levels of neuroticism and extraversion correlate with the job satisfaction.

Objective:To observe the occurrence of epithelial-mesenchymal transition (EMT) in cervical cancer cell line Siha irradiated by X-rays with clinical conventional fraction radiotherapy model and investigate the role of exosomes in this process.Methods:Siha cells were irradiated by 6 MV-X rays with 50 Gy in 25 fractions. EMT was evaluated by cell morphology, EMT biomarkers and cell migration and invasion ability. Exosomes released from cells were detected by transmission electron microscopy and nanoparticle tracking analysis (NTA), and its function in EMT was explored by using an exosome inhibitor GW4869 (10 μmol/L).Results:After irradiation, EMT phenomenon was induced in the survived Siha cells, including the incidence of mesenchymal phenotype, upregulation of epithelial marker E-cadherin ( t=9.66, P<0.05), downregulation of mesenchymal marker N-cadherin ( t=41.61, P<0.05), and increase of cell migration and invasion abilities ( t=6.11, 13.22; P<0.05). Meanwhile, the secretion of exosomes was also increased after irradiation ( t=7.51, P<0.05). When the cells were pre-treated with GW4869, radiation-induced exosome secretion was reduced ( t=7.28, P<0.05), so that radiation-induced EMT was reversed. Conclusions:Ionizing radiation with clinical conventional fraction radiotherapy model promotes EMT of cervical cancer cells through increasing the secretion of exosomes.
