The Spt-Ada-Gcn5-acetyltransferase (SAGA) is an ancillary transcription initiation complex which is highly conserved. The ADA1 (alteration/deficiency in activation 1, also called histone H2A functional interactor 1, HFI1) is a subunit in the core module of the SAGA protein complex. ADA1 plays an important role in plant growth and development as well as stress resistance. In this paper, we performed genome-wide identification of banana ADA1 gene family members based on banana genomic data, and analyzed the basic physicochemical properties, evolutionary relationships, selection pressure, promoter cis-acting elements, and its expression profiles under biotic and abiotic stresses. The results showed that there were 10, 6, and 7 family members in Musa acuminata, Musa balbisiana and Musa itinerans. The members were all unstable and hydrophilic proteins, and only contained the conservative SAGA-Tad1 domain. Both MaADA1 and MbADA1 have interactive relationship with Sgf11 (SAGA-associated factor 11) of core module in SAGA. Phylogenetic analysis revealed that banana ADA1 gene family members could be divided into 3 classes. The evolution of ADA1 gene family members was mostly influenced by purifying selection. There were large differences among the gene structure of banana ADA1 gene family members. ADA1 gene family members contained plenty of hormonal elements. MaADA1-1 may play a prominent role in the resistance of banana to cold stress, while MaADA1 may respond to the Panama disease of banana. In conclusion, this study suggested ADA1 gene family members are highly conserved in banana, and may respond to biotic and abiotic stress.

Objective To analyze the application value of modified anterior pelvic floor reconstruction operation in pelvic organ prolapse.Methods A retrospective analysis was adopted.A total of 141 patients with pelvic floor reconstruction surgery in the obstetrics and gynecology department of Chongqing Municipal Ma-ternal and Child Health Care Hospital from January 2020 to December 2021 were included.The patients were divided into the observation group(modified anterior pelvic floor reconstruction operation,n=78)and control group(classic anterior pelvic floor reconstruction operation,n=63)according to the operation methods.The perioperative indicators,pelvic organ prolapse quantitation(POP-Q)score before and after operation,objective cure rate after operation,recurrence situation and pelvic floor quality of life score before and after operation were compared between the two groups.Results There was no significant difference in the surgical time,bleeding volume,duration of antibacteriakl drug use,and length of hospital stay between the two groups(P＞0.05).The POP-Q scores after surgerynin the two groups were signbificantly increase compared with before operation,and the objective cure rate in postoperative 12 months in the observation group was significantly higher than that in the control group at 12 months after surgery(91％.0 vs.81.0％,P＜0.05).There was no recurrence in the observation group after one year follow-up,while there were two cases of recurrence in the control group.The scores of the pelvic floor distress inventory short form 20(PFDI-20),pelvic floor impact questionnake,short form 7(PFIQ-7),and pelvic organ prolapse/incontinence sexual function questionnaire-12(PISQ-12)in 1 month after surgery in the two groups had statisticallyu significant differences compared with those before surgery(P＜0.05).After one year of follow-up,the patient global impression of improvement(PGI-I)score in the observation group was significantly lower than that in the control group(P＜0.05).Con-clusion The modified anterior pelvic floor reconstruction operation can effectively improve the quality of life in the patients,moreover the patients are not easy to relapse,so which is a new type of operation worthy of promotion.

ObjectiveTo observe the effect of Xiaoke drink on insulin resistance in ob/ob mice and explore the mechanism. MethodEighteen ob/ob mice were randomly assigned into model， Xiaoke drink （17.68 g·kg^-1）， and atorvastatin （0.01 g·kg^-1） groups （n=6）， and six C57BL/6 mice were selected as the normal group. Mice in the normal and model groups were administrated with the same amount of distilled water. Fasting body weight， weekly food intake， and weekly water intake were measured at a fixed time. Fasting plasma glucose （FPG） and 2-hour post-load plasma glucose （2 hPG） were measured before and after 8-week intervention. After intervention， total cholesterol （TC）， triglyceride （TG）， fasting insulin （FINS）， Homeostasis Model Assessment-Insulin Resistance （HOMA-IR）， blood routine， and alkaline phosphatase （ALP） were measured. Western blot was employed to determine the expression levels of ubiquitin-specific protease 20 （USP20） and 3-hydroxy-3-methylglutaryl coenzyme A reductase （HMGCR） in the liver. The pancreas was stained with hematoxylin-eosin for observation. ResultCompared with the model group， the Xiaoke drink group showed decreased body weight of ob/ob mice （P<0.05， P<0.01）， declined growth trend of body weight （P<0.05， P<0.01）， reduced weekly average water intake， lowered levels of FPG， 2 hPG， TC， and HOMA-IR （P<0.05， P<0.01）， and down-regulated expression level of USP20 in the liver （P<0.05）. HMGCR content was positively correlated with USP20 expression. In addition， Xiaoke drink promoted the recovery of islet tissue morphology and function in ob/ob mice. ConclusionXiaoke drink can ameliorate insulin resistance in ob/ob mice by inhibiting USP20/HMGCR expression， reversing cholesterol biosynthesis process， and reducing cholesterol level.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective To investigate the changing distribution and antibiotic resistance profiles of clinical isolates of Staphylococcus in hospitals across China from 2015 to 2021.Methods Antimicrobial susceptibility testing was conducted for the clinical isolates of Staphylococcus according to the unified protocol of CHINET(China Antimicrobial Surveillance Network)using disk diffusion method and commercial automated systems.The CHINET antimicrobial resistance surveillance data from 2015 to 2021 were interpreted according to the 2021 CLSI breakpoints and analyzed using WHONET 5.6.Results During the period from 2015 to 2021,a total of 204,771 nonduplicate strains of Staphylococcus were isolated,including 136,731(66.8％)strains of Staphylococcus aureus and 68,040(33.2％)strains of coagulase-negative Staphylococcus(CNS).The proportions of S.aureus isolates and CNS isolates did not show significant change.S.aureus strains were mainly isolated from respiratory specimens(38.9±5.1)％,wound,pus and secretions(33.6±4.2)％,and blood(11.9±1.5)％.The CNS strains were predominantly isolated from blood(73.6±4.2)％,cerebrospinal fluid(12.1±2.5)％,and pleural effusion and ascites(8.4±2.1)％.S.aureus strains were mainly isolated from the patients in ICU(17.0±7.3)％,outpatient and emergency(11.6±1.7)％,and department of surgery(11.2±0.9)％,whereas CNS strains were primarily isolated from the patients in ICU(32.2±9.7)％,outpatient and emergency(12.8±4.7)％,and department of internal medicine(11.2±1.9)％.The prevalence of methicillin-resistant strains was 32.9％in S.aureus(MRSA)and 74.1％in CNS(MRCNS).Over the 7-year period,the prevalence of MRSA decreased from 42.1％to 29.2％,and the prevalence of MRCNS decreased from 82.1％to 68.2％.MRSA showed higher resistance rates to all the antimicrobial agents tested except trimethoprim-sulfamethoxazole than methicillin-susceptible S.aureus(MSSA).Over the 7-year period,MRSA strains showed decreasing resistance rates to gentamicin,rifampicin,and levofloxacin,MRCNS showed decreasing resistance rates to gentamicin,erythromycin,rifampicin,and trimethoprim-sulfamethoxazole,but increasing resistance rate to levofloxacin.No vancomycin-resistant strains were detected.The prevalence of linezolid-resistant MRCNS increased from 0.2％to 2.3％over the 7-year period.Conclusions Staphylococcus remains the major pathogen among gram-positive bacteria.MRSA and MRCNS were still the principal antibiotic-resistant gram-positive bacteria.No S.aureus isolates were found resistant to vancomycin or linezolid,but linezolid-resistant strains have been detected in MRCNS isolates,which is an issue of concern.

Objective:To construct a training model for non-psychiatric psychological specialist nurses in general hospitals, providing reference for the selection, training, management, and evaluation of psychological specialist nurses.Methods:From November 2022 to April 2023, a preliminary draft of the training model for non-psychiatric psychological specialist nurses in general hospitals was developed through literature review and semi-structured interviews. From May to July 2023, the Delphi method was used to conduct two rounds of expert consultations with 29 experts from seven provinces and municipalities directly under the central government, including Shanxi, Beijing and Anhui, etc. Based on expert opinions, the final training model for non-psychiatric psychological specialist nurses in general hospitals was formed. The enthusiasm of experts was expressed by the questionnaire response rate, the degree of authority was expressed by the expert authority coefficient, and the degree of coordination of expert opinions was expressed by Kendall's coordination coefficient.Results:In two rounds of expert consultations, the questionnaire response rate was 100.00% (29/29) for both rounds, and the expert authority coefficients were 0.884 and 0.916, and Kendall's coordination coefficients were 0.085-0.203 and 0.084-0.228 (all P<0.05). The final training model for non-psychiatric psychological specialist nurses in general hospitals included five primary indicators of training objectives, training content, training methods, training process, and training evaluation, 22 secondary indicators, and 92 tertiary indicators. Conclusions:The training model for non-psychiatric psychological specialist nurses in general hospitals constructed is scientific and practical, and has guiding significance for the selection, training, assessment and evaluation of psychological specialist nurses in China.

Objective:To explore the influence of temperament between parenting style and externalizing problem behaviors in school-age children.Methods:In October 2017, a stratified cluster sampling method was used to conduct a questionnaire survey among 380 school-age children in Aruhorqin Banner, Chifeng City, Inner Mongolia Autonomous Region. All the school-age children were assessed by the Achenbach child behavior checklist, parenting style scale, and middle childhood temperament questionnaire.Mediation models were established by the PROCESS macro program of SPSS, and the mediating effect was tested by the Bootstrap method.Results:The scores of various scales for school-age children were as follows: father's authoritative parenting style(3.77±1.11), father's authoritarian parenting style(1.55±0.68), father's indulgent parenting style(1.25±0.57), mother's authoritative parenting style(3.86±1.16), mother's authoritarian parenting style(1.64±0.73), mother's indulgent parenting style(1.25±0.61), activity level(2.42±0.71), attention dispersion(3.78±0.81), externalization problem behaviors 3.0(4.0).For school-age children, the scores of externalization problem behaviors were negatively correlated with the scores of authoritative parenting style( r=-0.15, -0.11, both P<0.05), and positively correlated with authoritarian and indulgent parenting style ( r=0.17-0.33, all P<0.05). The scores of externalization problem behaviors were positively correlated with eight temperament dimensions, such as adaptability, emotional essence, reaction threshold, attention dispersion, persistence, rhythmicity, activity level and reaction intensity( r=0.17-0.42, all P<0.05). After controlling for age and gender, attention dispersion played a masking effect on the influence of authoritative parenting style on children's externalizing problem behaviors, with the indirect effect accounting for 21.05%(|0.04/-0.19|) and 26.67%(|0.04/-0.15|) of the direct effect respectively. Attention dispersion partially mediated the impact of father's authoritarian parenting style on children's externalization problem behaviors, with the mediating effect accounting for 10.71%(0.03/0.28) of the total effect. Response intensity partially mediated the impact of authoritarian parenting style on children's externalizing problem behaviors, with the mediating effect accounting for 25.00%(0.07/0.28) and 27.58%(0.08/0.29) of the total effect respectively. Conclusion:Temperament plays a mediating role between parenting styles and externalizing problem behaviors among school-age children. A nurturing environment suitable for children's temperament should be created to prevent the occurrence of externalizing problem behaviors among school-age children.

Objective:To explore the clinical characteristics and distribution of Tranditional Chinese Medicine (TCM) syndrome types of refractory tic disorders in children based on clustering analysis.Methods:A cross-sectional study. 183 children aged 3-18 years with refractory tic disorders from pediatric encephalopathy outpatient department of the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine who met the inclusion criteria from October 2015 to January 2022 were recruited. Frequency descriptive analysis, systematic clustering analysis and principal component analysis were conducted by Microsoft Office Excel 2016 and IBM SPSS Statistics 26.0 to explore the clinical characteristics and syndrome distribution of the disease.Results:The TCM symptoms of 183 children with refractory tic disorders were clustered into 6 categories, and finally 5 types of syndrome were obtained, among which the syndrome of spleen deficiency and liver hyperactivity mixed with dampness accounted for the largest proportion (27.32%), followed by the syndrome of phlegm-fire disturbing spirit (21.31%), the syndrome of wind-heat invading lung (18.03%), the syndrome of phlegm-qi stagnation (17.49%), and the syndrome of dampness and yin deficiency (15.85%).Conclusion:Through the mining and analysis of the outpatient information of pediatric encephalopathy in our hospital, the common syndrome differentiation types of refractory tic disorder are obtained, which can provide a reference for the TCM syndrome differentiation types of refractory tic disorder in children.
