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.

Objective:To explore the ventilation strategy of using pressure controlled ventilation-volume guaranteed (PCV-VG) mode combined with personalized positive end expiratory pressure (PEEP) during surgery, and its impact on oxygenation function and incidence of postoperative pulmonary complications (PPCs) in patients undergoing brain tumor surgery.Methods:Sixty patients who underwent elective brain tumor surgery at the Linyi People′s Hospital from January 2023 to June 2023 were selected. The patients were randomly divided into PCV-VG ventilation mode group (T group) and volume controlled ventilation (VCV) mode group (C group) using a random number table method, with 30 patients in each group. One patient was excluded from group T due to changes in the condition, and 29 patients were actually included. Group T adopted PCV-VG ventilation mode and searched for the maximum dynamic lung compliance (Cdyn) by titrating PEEP. The PEEP corresponding to the maximum Cdyn value was the optimal PEEP, which was maintained until the end of mechanical ventilation. Group C adopted a ventilation mode of VCV plus 5 cmH 2O fixed value PEEP. All patients underwent arterial blood gas analysis before anesthesia induction (T 1), 15 minutes after setting ventilation mode (T 2), and 15 minutes after extubation (T 3), recording arterial oxygen partial pressure (PaO 2), carbon dioxide partial pressure (PaCO 2), lactate (Lac), and blood glucose (Glu), and calculating oxygenation index (PaO 2/FiO 2). The levels of white blood cells (WBC), C-reactive protein (CRP), and procalcitonin (PCT) were recorded before and 72 hours after surgery. The incidence of postoperative PPCs at 72 hours was observed. Results:There was a statistically significant difference in the grouping effect and time effect of PaO 2 and PaCO 2 between group C and group T (all P<0.05), while there was no statistically significant difference in the interaction effect (all P>0.05); The differences in grouping effects, time effects, and interaction effects of PaO 2/FiO 2 between group C and group T were statistically significant (all P<0.05); The average value of the optimized PEEP obtained by T-group titration was 7.48 cmH 2O, corresponding to an average platform pressure (Pplat) of 14.90 cmH 2O, and an average value of 53.37 ml/cmH 2O corresponding to the maximum Cdyn value. Compared with the Pplat and Cdyn corresponding to the fixed value of 5 cmH 2O PEEP in Group C, the Pplat corresponding to the optimized PEEP in Group T was lower than that in Group C ( P<0.05), and the Cdyn was higher than that in group C ( P<0.05). The CRP level and incidence of PPCs in group T after 72 hours of surgery were significantly lower than those in group C (all P<0.05). Conclusions:Compared with VCV, the ventilation mode of PCV-VG combined with personalized PEEP can improve intraoperative lung ventilation and oxygenation function in patients with brain tumors, reduce the occurrence of pulmonary inflammation 72 hours after surgery, and lower the incidence of PPCs.

Objective: To investigate the awareness, sexual behavior characteristics and infection status of AIDS among male floating population in Anhui Province, so as to provide insights into formulating prevention and control measures for male floating population. Methods: Male floating population of three occupations including construction workers, enterprise workers, and business operators in Wuhu, Tongling, Hefei, and Fuyang cities were selected using stratified cluster random method from April to August 2021. Demographic information, knowledge of AIDS and high-risk behaviors were collected through questionnaires surveys. The results of HIV, syphilis and hepatitis C virus (HCV) antibody testing were collected through laboratory tests. Awareness rate of AIDS knowledge, sexual behavior characteristics, and positive rates of HIV, syphilis, and HCV among male floating population of different occupations were analyzed. Results: A total of 1 616 people were enrolled, including 1 016 construction workers (62.87%), 253 enterprise workers (15.66%) and 347 business operators (21.47%), and had a mean age of (40.63±12.32) years. The overall awareness rate of AIDS knowledge among male floating population was 89.54%, the awareness rates of business operators, construction workers, and enterprise workers were 98.33%, 88.29% and 82.61%, respectively, and the difference was statistically significant (P<0.05). The proportions of consistent condom use during sexual intercourse with a spouse or cohabitant, during commercial sexual encounters, and with casual partners in the past year were 7.15% (91/1 273), 64.00% (16/25) and 50.00% (8/16), respectively. The proportions of construction workers, enterprise workers, and business operators who used condoms every time they had sexual behavior with their spouses/cohabitants in the past year were 4.54%, 11.63%, and 15.60%, respectively, with statistically significant differences (P<0.05). One case of HIV, one case of syphilis, and three cases of HCV antibody were detected. Conclusion The overall awareness rate of AIDS knowledge among the male floating population in Anhui Province is relatively high, but unsafe sex behaviors exist, which may lead to the risk of HIV infection.

Objective:To compare the clinical characteristics and prognosis of bacterial liver abscess in patients with or without diabetes mellitus (DM), to provide a reference for clinical diagnosis and treatment.Methods:Patients with bacterial liver abscesses hospitalized in Tongren Hospital, Shanghai Jiao Tong University School of Medicine from January 2016 to August 2021 were enrolled, and their clinical data were collected. The patients were divided into diabetic and non-diabetic groups for comparison according to whether they had comorbid DM. Statistical analysis was performed by chi-square test or Fisher′s exact test, and multivariate logistic regression analysis.Results:A total of 131 patients with bacterial liver abscesses were included, including 47 cases in the diabetic group and 84 cases in the non-diabetic group. The percentages of platelet count <100×10 9/L, C-reactive protein>10 mg/L, and total bilirubin>17.5 μmol/L were lower in the diabetic group than that in the non-diabetic group, and the differences were all statistically significant ( χ2=3.90, 6.44 and 5.56, respectively, all P<0.05). The percentage of multiple abscesses in the diabetic group was 10.6%(5/47), which was lower than 29.8%(25/84) in the non-diabetic group, and the difference was statistically significant ( χ2=6.24, P=0.012). The positive rate of pus culture for Klebsiella pneumoniae was 64.9%(24/37) in the diabetic group, which was higher than 41.5%(27/65) in the non-diabetic group, with a statistically significant difference ( χ2=5.13, P=0.023). The incidences of pleural effusion and abscesses at other sites in the diabetic group were 29.8%(14/47) and 10.6%(5/47), respectively, which were both higher than 14.3%(12/84) and 1.2%(1/84) in the non-diabetic group, respectively, and the differences were statistically significant ( χ2=4.55, Fisher′s exact test, both P<0.05). The proportion of hospital stays>21 d was 34.0%(16/47) in the diabetic group, which was higher than 16.7%(14/84) in the non-diabetic group, with a statistically significant difference ( χ2=5.15, P=0.023). DM (odds ratio ( OR)=2.654, 95% confidence interval ( CI) 1.020 to 6.907, P=0.046) and abscess maximum diameter>10 cm ( OR=11.045, 95% CI 4.493 to 27.154, P<0.001) were significant risk factors for hospital stay>21 d. Conclusions:Bacterial liver abscesses combined with DM are more common with single abscess, a higher rate of Klebsiella pneumoniae infection, and more likely to develop pleural effusions and abscesses at other sites. Liver abscesses>10 cm in maximum diameter and comorbid DM would prolong hospital stay.

Objective:To investigate the clinical manifestations of population following COVID-19 by using questionnaires.Methods:COVID-19 among anesthesia workers and the surrounding population was investigated between 11 November 2022 and 31 December 2022 in China.The Tencent electronic questionnaire(ID.11492813) was sent to different WeChat groups of the Association of Anesthesiologists or Society of Anesthesiologists via the WeChat platform of the medical personnel in China. The survey was conducted between January 7 and January 15, 2023. Results:A total of 17 000 questionnaires were issued for this survey, 11 060 valid questionnaires from 31 provinces and autonomous regions were collected all over the country, with a recovery rate of 65.059%.There were 10068 (91.037%) participants diagnosed as having COVID-19, and among of them, 47.606% were male and 52.394% were female. The main post-COVID-19 clinical manifestations included fever (85.777%), cough (83.731%), fatigue (75.338%), parasomnia (64.352%), limb soreness (58.890%), dizziness, headache, tinnitus (38.617%), loss or abnormality of taste (37.763%), and loss or abnormality of smell (30.960%); peripheral neuralgia was usually found within 3 days after positive nucleic acid test or positive antigen test; there were 2 963 cases accompanied with sweating, and among of them, 47.25% were male and 52.75% were female, and 37.80% of these participants continued to sweat after the nucleic acid test or antigen test became negative. There were 1 151 cases with premature heart beats among the study population, and the symptoms aggravated following COVID-19 were found in 34.32% of these patients.Conclusions:In addition to the respiratory system, the central and peripheral nerves of patients are also affected following COVID-19, and the peripheral and central nerve disorders last until several days after negative nucleic acid test or antigen test, suggesting that anesthesiologists should pay more attention to monitoring of various nerve function and impact of surgery and anesthetic drugs on the stress response of the body in such patients.

Objective:To establish an evaluation index system of home care quality for caregivers of children aged ≤3 years with burns.Methods:The combined approach of qualitative and quantitative research was used, and the fundamental principles of constructing an index system was followed. From January to February 2022, through literature analysis, conducting a semi-structured interview on 6 female nurses aged 31 to 51 years who worked for more than 10 years in the Department of Burns, Plastic Surgery, and Aesthetic Medicine of General Hospital of Ningxia Medical University, as well as 15 caregivers (11 females and 4 males) of hospitalized children with burns aged 28 to 54 years who received professional training from nursing staff, a preliminary evaluation index system of home care quality for caregivers of children ≤3 years old with burns was established using Maslow's hierarchy of needs as theoretical guidance. From March to June 2022, the Delphi method was applied to conduct inquiry by correspondence with 15 experts in relevant fields who met the inclusion criteria and were employed in general hospitals, specialized hospitals, and universities in the Ningxia Hui Autonomous Region (with their general information being recorded), and the evaluation index system was established and the weights of indicators at all levels were determined by the analytic hierarchy process. The effective recovery ratio of the inquiry form was calculated to determine the level of enthusiasm of experts, the average authority coefficient of all indicators was calculated to determine the level of expert authority, the average importance assignment and full score ratio of all indicators were calculated to determine the concentration of expert opinions, and the average Kendall's harmony coefficients and mean coefficient of variation for all indicators were calculated to determine the degree of coordination of expert opinions. The Kendall's harmony coefficients for the first level indicators, the total second level indicators, and the total third level indicators in each round of correspondence inquiry were statistically analyzed with chi-square test.Results:The preliminary evaluation index system of home care quality for caregivers of children ≤3 years old with burns included 5 first level indicators, 13 second level indicators, and 55 third level indicators. The majority of the 15 experts were women, aged 32-56 years, all with a bachelor's degree or above education background, intermediate or above professional titles, and worked for 14-31 years. The effective recovery ratios of the first and second rounds of inquiry forms were 1 (15/15) and 0.93 (14/15), respectively. The average authority coefficients of all indicators in the first and second rounds of correspondence inquiries were 0.87 and 0.90, respectively. The average importance assignment and average full score ratio of all indicators were 4.25 and 0.68 respectively in the first round of inquiry, and 4.39 and 0.70 respectively in the second round of inquiry. In the first and second rounds of inquiries, the average Kendall's harmony coefficients for all indicators were 0.50 and 0.62, respectively, and the average coefficients of variation for all indicators were 0.15 and 0.14, respectively. The Kendall's harmony coefficients of the five first level indicators (physiological needs, safety needs, needs for love and belonging, needs for respect, and needs for self-realization), the total second level indicators, and the total third level indicators in the first and second rounds of correspondence inquiries were statistically significant (with χ2 values of 22.18, 20.36, 23.42, 25.81, 21.44, 124.73, 524.05 and 24.27, 19.85, 22.39, 27.52, 20.83, 102.38, 503.27, respectively, P<0.05). The final evaluation index system of home care quality for caregivers of children ≤3 years old with burns included 5 first level indicators, 13 second level indicators, and 56 third level indicators. The weights of the first level indicators for physiological needs, safety needs, needs for love and belonging, needs for respect, and needs for self-realization were 0.343, 0.371, 0.091, 0.076, and 0.127, respectively. The weights of the second level indicators were 0.024 to 0.192, and the weights of the third level indicators were 0.001 to 0.089. Conclusions:The evaluation index system of home care quality for caregivers of children ≤3 years old with burns established on the basis of Maslow's hierarchy of needs theory is scientific and reliable, and can serve as a reference for home care of children with burns in this age group.

Objective:To comprehensively evaluate the clinical application status of oral movement intervention in preterm infants, analyze the obstacles in the process of clinical application of the best evidence and formulate countermeasures, so as to provide reference for clinical evidence transformation.Methods:Based on the theoretical guidance of the "Clinical Application Model of Evidence" of the Joanna Briggs Institute (JBI) Evidence-Based Health Care Center in Australia, 12 pieces of the best evidence for oral movement intervention in premature infants were included, and 13 review indicators were formulated. From May to July 2021, a status review was conducted in Department of Neonatology in Suzhou Hospital Affiliated to Nanjing Medical University. The Ottawa Model of Research Use (OMRU) was used to analyze the barriers and facilitators in the process of evidence application and formulate effective intervention strategies and action plans.Results:Among the 13 reviewed indicators, only 2 items had a compliance rate of 100%, 2 items had a compliance rate of more than 60%, 6 items had a compliance rate of less than 60%, and 3 items had a compliance rate of 0. The main obstacle factors were lack of standardized process and assessment tools, lack of oral motor intervention related knowledge and training for preterm infants, increased clinical workload due to evidence transformation and the low level of knowledge and action among medical staff. The main promoting factors were support from managers for the development and reform of evidence-based learning, good learning atmosphere for doctors and nurses, departments with material and hardware conditions for evidence transformation, effective evidence, and parents' willingness to accept the reform. Through analysis, countermeasures were drawn up to formulate feasible and suitable standardized procedures and introduce assessment tools. Managers formulated and implemented incentive policies, adopted various training methods, strengthened quality supervision in the process of evidence transformation, timely gave feedback of progress results and improved human resource allocation.Conclusions:There is a certain gap between the best evidence of oral movement intervention in premature infants and the current clinical nursing practice. It is necessary to formulate corresponding countermeasures according to the obstacle factors and promoting factors, promote the evidence transformation and constantly promote the evidence-based practice of oral movement intervention in premature infants.
