Objective:To investigate the efficacy and safety of high intensity focused ultrasound(HIFU)com-bined with endometrial thermal Balloon ablation(TBEA)in the treatment of menorrhagia associated with adenomy-osis(AM).Methods:A retrospective cohort study was performed on clinical data of 77 patients with menorrhagia associated with adenomyosis(AM)in Mianyang Central Hospital from January 2021 to December 2022.According to different treatment methods,they were divided into HIFU combined with TBEA(HIFU+TBEA group,n=26)and HIFU combined with gonadotropin-releasing hormone agonist(GnRH-a)and levonorgestrel-releasing intrauterine system(LNG-IUS)(HIFU+drug group,n=51).The pictorial blood loss assessment chart(PBAC)at different fol-low-up time after HIFU ablation was used as the main outcome index,dysmenorrhea score(NRS),serum CA125 level,re intervention rate,treatment effectiveness rate and adverse reactions were used as the secondary out-come indexes.Evaluate the efficacy and safety of HIFU combined with TBEA in the treatment of menorrhagia as-sociated with AMby comparing the difference of outcome indexes between two groups before and after treatment at different times.Results:Compared with pre-treatment,the PBAC score,NRS score and CA125 level were signif-icantly decreased after treatment in both groups(P<0.05).Compared with HIFU+drug group,PBAC score of HIFU+TBEA group decreased more at 6,9 and 12 months after treatment(P<0.05),but there was no signifi-cant difference in PBAC score at 1 and 3 months after treatment(P>0.05).There was no significant difference in NRS scores between the two groups at 1,3,6,9 and 12 months after treatment(P>0.05).There was no signifi-cant difference in reintervention rate between HIFU+TBEA group(11.54% )and HIFU+drug group(21.57% )after treatment(P>0.05).There was no significant difference in treatment effectiveness between HIFU+TBEA group(80.77% )and HIFU+drug group(70.59% )(P>0.05).The adverse reactions of the two groups after treatment were graded as SIR A-B,and no serious adverse events occurred.Conclusions:The combination of HIFU and TBEA has good efficacy and safety in the treatment of AM,and can be used as a long-term manage-ment program for patients with no fertility needs,especially for AM patients with menorrhagia,which also has good clinical application value.

Objective:To analyze the patterns of antibacterial agents in Chinese children surveyed by the China multi-center monitoring network for the application of antibacterial agents in children and neonates in 2019 by using World Health Organization (WHO) Access, Watch, Reserve and Not-recommended (AWaRe) and typical anatomical/therapeutic/chemical (ATC) in this study.Methods:The cross-sectional method was adopted.A multi-center cross-sectional survey was conducted on one day from September to December 2019.The information of all inpatients taking antibiotics was uploaded to the network-based data collection system (https: //garpec-31.mobilemd.cn/login.aspx? relogin=true). This study covered 13 hospitals from 10 provinces and cities in China.All hospitalized children in the Respiratory Department, Infectious Disease Department, General Surgery Department, Pediatric Intensive Care Units, Neonatal Intensive Care Units and Neonatology joined in this survey.The clinically used antibacterial agents were classified by AWaRe and ATC, and the AWaRe and ATC distributions of antibacterial agents prescribed for Chinese children and neonates were described.Results:Of the 2 644 antibiotic prescriptions included from 13 hospitals, 2 134 (80.71%) were for children and 510 (19.29%) were for neonates.Of all antibiotic prescriptions, there were 368 (13.92%) Access antibiotics prescriptions, 1 973 (74.62%) Watch prescriptions, 60 (2.27%) Reserve prescriptions and 243 (9.19%) Not-recommended prescriptions.The top-five antibiotics prescribed for children and neonates were third-generation cephalosporins (1 056, 39.94%), macrolides (492, 18.61%), carbapenems (275, 10.40%), beta lactam-beta lactamase inhibitors (246, 9.30%), and second-generation cephalosporins (136, 5.14%). The use ratios of Access, Watch, Reserve and Not-recommended antibiotics in each center ranged from 0 to 30.00%, 36.67% to 97.20%, 0 to 17.02% and 0 to 33.33%, respectively.In 1 360 antibiotic prescriptions for children and neonates with pneumonia, there were 152 (11.18%) Access antibiotics, 1 051 (77.28%) Watch antibiotics, 37 (2.72%) Reserve antibiotics, and 120 (8.82%) Not-recommended antibiotics.The top-five antibiotics prescribed for children with pneumonia were third-generation cephalosporins (522, 38.38%), macrolides (388, 28.53%), beta lactam-beta lactamase inhibitors (141, 10.37%), carbapenems (117, 8.6%) and penicillins (49, 3.60%).Conclusions:Watch antibiotics and broad spectrum antibiotics such as third-generation cephalosporins and macrolides prone to induce resistance are the main antibacterial agents used in Chinese children and neonates with pneumonia.Broad-spectrum antibiotics may be overused in Chinese children and neonates.

OBJECTIVE: To compile the Chinese Musculoskeletal Questionnaire(CMQ) and test its reliability and validity. METHODS: The initial CMQ was formed through studying literatures, interviewing professional workers who have work-related musculoskeletal disorders(WMSDs) and investigation with occupational health and ergonomics experts. Then, 436 and 443 manufacturing workers were selected as prediction and verification samples respectively by convensence sampling method. The reliability and validity of the CMQ were tested by item analysis, exploratory factor analysis and confirmatory factor analysis. RESULTS: i) The CMQ composed of 48 items with item analysis. ii) Nine common factors of CMQ were extracted using exploratory factor analysis, which explained 70.721% of WMSDs variance. iii) The results of confirmatory factor analysis showed that the ratio of chi-square to degree of freedom was 3.380, the comparative fit index was 0.781, the Tucker-Lewis index was 0.764, the root mean square error of approximation was 0.073, and the standardized root mean square residual was 0.068. iv) The results showed that the item reliabilities of the 9 common factors of CMQ such as upper and lower limbs posture load, neck posture load, back posture load, job demand, social support, job control, job environment, job system and job facilities were 0.205-0.841, the composite reliabilities were 0.545-0.894, and the convergence efficiencies were 0.377-0.834. The correlation coefficients between the common factors were less than its square root of the convergence validities. CONCLUSION: The CMQ has good reliability and validity, and is a reliable and effective tool for evaluating WMSDs.
