Objective:To investigate the genetic subtypes and drug resistance monitoring of newly reported human immunodeficiency virus (HIV) infection/AIDS virus in Anhui Province from 2020 to 2023.Methods:An observational design study was used to collect blood samples from patients diagnosed with HIV/AIDS in the AIDS Prevention and Control Department of Anhui Provincial Center for Disease Control and Prevention from January 2020 to December 2023.The HIV-1 pol gene was amplified by reverse transcription-nested PCR, and the genetic subtypes were identified by phylogenetic tree analysis using MEGA 7.0 software. The mutation sites of drug resistance were analyzed by the online software tool of Stanford University′s HIV Drug resistance database. The influencing factors of drug resistance before treatment were analyzed by multivariate logistic analysis.Results:A total of 335 plasma samples were collected, and 332 HIV-1 pol gene sequences were obtained successfully. The main gene subtypes were CRF01-AE, accounting for 35.55% (118/332), followed by CRF07-BC, B and B+C types [29.22% (97/332), 11.74% (39/332), 9.93% (33/332)]. The total drug resistance rate before treatment was 30.12%(32/100), and the drug resistance rate of protease inhibitor (PIs) in HIV-1 was 6.33% (21/332). The drug resistance rate of nucleoside reverse transcriptase inhibitors (NRTI) before treatment was 6.33% (21/332). The drug resistance rate of non-nucleoside reverse transcriptase inhibitors (NNRTI) before treatment was 17.47% (58/332).The comparison of drug resistance rate of different drug types showed statistical significance ( χ2=30.435, P<0.05).Among the 100 cases of drug resistance, the main mutation point of HIV-1 protease inhibitor was Q58E (21.00%), and the main mutation point of nucleoside reverse transcriptase inhibitor was M184V/I (6.00%). Non-nucleoside reverse transcriptase inhibitor resistance mutation points mainly K103N (22.00%).There were statistically significant differences in the starting time of antiviral therapy, the number of CD4 +T cells at baseline and the drug resistance rate of gene subtypes (the chi-square values are respectively 24.152, 32.516, 11.652, P<0.05).Multivariate logistic analysis showed that the baseline CD4 +T cell count was <200/μl, subtype B, subtype B+C, CRF01-AE subtype, CRF55-01B subtype and 01-BC subtype was the influential factor of drug resistance before treatment (the chi-square values are respectively 4.577, 8.202, 4.416, 5.206, 7.603 and 4.804, P<0.05). Conclusion:The newly reported HIV/AIDS population in Anhui Province from 2020 to 2023 has a variety of viral gene subtypes, and NNRTIs are the main types of drug resistance gene mutations before treatment. Attention should be paid to the number of baseline CD4 +T cells, the duration of antiviral treatment, and the distribution of gene subtypes to reduce the drug resistance of HIV/AIDS patients before treatment.

ObjectiveTo understand the utilization of preconception healthcare services and the influencing factors among the women expecting additional childbirth in Jiading District， Shanghai， and to provide references for promoting the utilization of preconception healthcare services under the new population policy. MethodsA questionnaire survey on the utilization of preconception healthcare services and related influencing factors was carried out among 682 women expecting additional childbirth across six subdistricts in Jiading District， Shanghai. The results were statistically analyzed. ResultsThe average age of the women was （31.7±4.5） years， 30.2% of whom were ≥35 years old. The proportion of women having their third or subsequent children was low， at 16.4%. A significant majority， 92.4%， were found to have various risk factors during initial pregnancy screening. The utilization rate of preconception healthcare services among women seeking additional childbirth was relatively low at 26.7%. Awareness of the free preconception check-up program in Jiading District was also low at 28.6%， and the utilization rate for these services was even lower at 7.69%. Unplanned pregnancies were the primary reason for not utilizing preconception healthcare services， accounting for 63.6%. The results of multifactorial binary logistic regression analysis showed that the utilization rate of preconception healthcare services before the current pregnancy was higher for women aged between 35 and 39 compared to women aged ≤29 years old （OR=1.789， 95%CI： 1.033‒3.099）. Women with planned pregnancies had a higher utilization of preconception healthcare services prior to this pregnancy （OR=4.164， 95%CI： 2.627‒6.602）. Women who had received preconception care prior to their first birth had a higher utilization rate of preconception care prior to the current pregnancy （OR=7.534， 95%CI： 4.954‒11.456）. Women without a family history of chronic diseases had a higher utilization rate of preconception healthcare services （OR=1.903， 95%CI： 1.083‒3.345）. ConclusionUnder the context of three-child policy， the proportion of women seeking three or more children in Jiading District is low. Most of these women have risk factors identified during initial pregnancy screenings. The utilization rate of preconception healthcare services and the awareness of the free preconception screening program in Jiading District are both low. Unplanned pregnancies remain the primary reason for failing to receive timely preconception healthcare services. Age， whether the pregnancy was planned， whether the women had received preconception healthcare services before their first baby and family history of chronic diseases are the main factors affecting the utilization of preconception healthcare services. Relevant departments should enhance the promotion of preconception healthcare service programs， especially for women of childbearing age who have not yet given birth， so as to improve the utilization rate of preconception health care services.

Objective:To compare the clinical outcomes of anterolateral femoral interregional flap with turbocharge technique and traditional anterolateral femoral flap in repair of large limb wounds.Methods:Clinical data of 38 patients with large limb surface wound(11 cm×39 cm-16 cm×65 cm)admitted to the Sir Run Run Shaw Hospital,Zhejiang University School of Medicine from May 2018 to May 2022 were retrospectively analyzed.Eighteen patients were treated by anterolateral thigh perforator flap combined with superficial circumflex iliac artery flap(ALTP-SCIAP)with turbocharge technique(interregional flap group);while 20 patients were treated with unilateral or bilateral anterolateral femoral flaps,combined with skin grafting if necessary(traditional anterolateral femoral flap group).The survival of skin flap,repair of donor area,complications and patient satisfaction were compared between the two groups.Results:In interregional flap group,18 flaps were harvested and transplanted,the flap width,length and the viable area were(9.9±2.0)cm,(44.2±3.5)cm and(343.2±79.9)cm2,respectively.In traditional anterolateral femoral flap group,29 flaps were harvested and transplanted,the flap width,length and the viable area were(11.0±2.8)cm,(21.7±3.2)cm and(186.4±49.2)cm2,respectively.There were significant differences in the flap length and the viable area between the two groups(t=22.365 and 8.345,both P<0.05).In the interregional flap group,the donor site of flap was closed by direct suture in 11 flaps,by skin retractor assisted suture in 6 flaps,and by skin grafting in one flap.In traditional anterolateral femoral flap group,the donor site of flap was closed by direct suture in 12 flaps,by skin retractor assisted suture in 11 flaps,and by skin grafting in 6 flaps.The skin graft rates of the two groups were 5.6%(1/18)and 20.7%(6/29),respectively(χ2=2.007,P>0.05).The interregional flap group had lower postoperative complications rate(5.6%vs.35.0%,χ2=4.942,P<0.05)and higher patient satisfaction rate(94.4%vs.70.0%,χ2=4.448,P<0.05)than traditional anterolateral femoral flap group.Conclusion:Compared with the traditional anterolateral femoral flap,the anterolateral femoral interregional flap with turbocharge technique has a larger flap area,most of the donor areas of the flap can be sutured directly without skin grafting and with less complications and a higher patient satisfaction rate.

Objective:To explore the relationship between family cumulative risk, non-adaptive cognitive emotion regulation, school climate and depression of junior high school students.Methods:From June to September 2022, a total of 1 136 junior high school students were surveyed by the family cumulative risk questionnaire, the cognitive emotion regulation strategy questionnaire, the self-rating depression scale for children and school climate scale.The mediating effect of non-adaptive cognitive emotion regulation and the moderating effect of school climate were tested by the Macro program PROCESS of SPSS 25.0 software.Results:Family cumulative risk score was 1.00(2.00), non-adaptive cognitive emotion regulation score was 21.00(8.00) and depression score was 7.00(9.00). (2) Family cumulative risk was significantly positively correlated with non-adaptive cognitive emotion regulation( r=0.28, P<0.01) and depression( r=0.43, P<0.01). There was a significantly positive correlation between non-adaptive cognitive emotion regulation and depression( r=0.41, P<0.01), and a significantly negative correlation between school climate and depression( r=-0.56, P<0.01). (3) Non-adaptive cognitive emotion regulation played a partial mediating role between family cumulative risk and depression, and the direct effect and mediating effect accounted for 80.49%(0.33/0.41) and 19.51%(0.08/0.41)of the total effect respectively.(4) School climate played a moderating role in the influence of family cumulative risk on non-adaptive cognitive emotion regulation. Under the condition of the level of school climate was high, the positive predicting effect of family cumulative risk on non-adaptive cognitive emotion regulation was significantly enhanced( Bsimple=0.34, P<0.001). Conclusion:Family cumulative risk plays a certain role in depression through the mediation of non-adaptive cognitive emotion regulation strategies and the regulation of school climate in junior high school students.
