OBJECTIVE To assess the scientific rigor， clarity and feasibility of the recommendations of the Guidelines for Evidence-based Use of Biological Agents for the Clinical Treatment of Osteoporosis （hereinafter referred to as the Guideline） through external review， in order to further revise and improve the Guideline recommendations. METHODS This study employed a cross-sectional survey research design， a convenience sampling method was adopted to select frontline medical workers in the field of osteoporosis （including clinical doctors， clinical pharmacists， and nurses） as well as patients or their family members. External review was conducted through a combination of closed-ended and open-ended electronic questionnaires to get feedback from them on the appreciation，clarity and feasibility of the 32 preliminary recommendations in the Guideline. RESULTS A total of 90 external review subjects from 15 hospitals were collected， including 45 clinical doctors， 15 clinical pharmacists， 15 nurses and 15 patients or their family members. The overall appreciation degree of recommendations was 99.38%， the overall clarity degree of recommendations was 98.92%， and the overall feasibility degree of recommendations was 99.65%. At the same time， 111 subjective suggestions were collected， which provided an important reference for the further improvement of the Guideline recommendations. Based on the above feedback， the Guideline steering committee and core expert group revised the wording of 12 draft recommendations without deletion， and finally determined 32 recommendations. CONCLUSIONS The external review provides an important basis for the final formation of the Guideline， further improves the scientific rigor， clarity and feasibility of the recommendations， and ensures the standardization， practicality and implementability of the Guideline.

Ovarian sclerosing stromal tumor(OSST)is a benign tumor originating from the ovarian sex cord-stroma,accounting for only 2%-6%of ovarian stromal tumors.It predominantly occurs in young women,and cases of OSST concurrently presenting with Meigs syndrome are extremely rare.This study reports a case of OSST,summarizes its clinical manifestations,and reviews relevant literature.The patient,a 22-year-old female,was admitted due to abdominal distension for 2 months,worsening over the past week.The physical examination results revealed abdominal distension,shifting dullness,mild tenderness,and no muscle tension or rebound tenderness.A mass measuring approximately 16.0 cm×14.0 cm×8.0 cm was palpated in the pelvic and abdominal cavity,with a firm texture,moderate mobility,and no tenderness.The gynecological ultrasound results showed a mixed cystic-solid echo of about 15.3 cm×14.0 cm×8.4 cm above the left side of the uterus,with clear boundaries,and fluid-filled dark areas in the pelvic and abdominal cavity,with a maximum anteroposterior diameter of about 11.9 cm.The-CT results revealed a cystic-solid mixed-density mass in the lower abdomen and right adnexal area,suggestive of a neoplastic lesion,with increased glucose metabolism in the solid portion,leaning toward malignancy.Carbohydrate antigen 125(CA125)was>800 U·mL-1,and pelvic puncture cytology indicated no cancer cells.The findings suggested a benign or borderline ovarian tumor,requiring differentiation from ovarian malignant tumors.Based on intraoperative observations and rapid pathological results,a left ovarian tumor enucleation was performed.Postoperative pathology confirmed ovarian sclerosing stromal tumor.Follow-up over 2 years showed no abnormalities.As a benign ovarian tumor,the clinical manifestations of OSST often mimic those of malignant tumors,leading to frequent misdiagnosis.Early diagnostic accuracy should be improved to develop the optimal treatment plan for patients.

Objective:To develop and validate the Pain nursing Competency Evaluation Questionnaire for Nursing Students to provide an effective tool for measuring the pain management competency of nursing students in China.Methods:The questionnaire was constructed through literature review, semi-structured interviews, focus group discussions, Delphi expert consultation, and a pre-survey. From September 2023 to January 2024, a convenience sampling method was used to select 250 nursing students from Hangzhou Normal University and Lishui University in Zhejiang Province for the survey. Reliability and validity of the developed questionnaire were tested. A random sample of 30 nursing students was selected for retesting after two weeks.Results:A total of 10 female experts were consulted through correspondence. The Pain Care Competency Evaluation Questionnaire for nursing students consists of 36 items. Through exploratory factor analysis, five common factors were extracted: pain health education, comprehensive pain assessment, pain screening and assessment, analgesic interventions, and analgesic side effects nursing, which together explained 61.695% of the variance. The content validity of the questionnaire was 0.96, and the item-level content validity index ranged from 0.900 to 1.000. The overall Cronbach′s α coefficient was 0.924, and the Cronbach′s α coefficients for the five dimensions ranged from 0.856 to 0.915. The test-retest reliability was 0.831. Conclusions:The Pain Care Competency Evaluation Questionnaire for nursing students developed in this study has good reliability and validity. It can be used as a tool to assess nursing students′ competency in pain care and provides a reference for the design and optimization of pain care courses and clinical practice programs for nursing students in undergraduate institutions.

Objective To investigate the impacts and mechanism of circular RNA polyribonucleotide nucleotidyltransferase 1(Circ-PNPT1)on glucose and lipid metabolism and offspring outcomes in rats with GDM through microRNA-345-3p(miR-345-3p)/lipid raft scaffold protein 2(FLOT2)axis.Methods 75 pregnant female rats were divided into normal control(NC)group,GDM group,si-NC group,si-Circ-PNPT1 group,and si-Circ-PNPT1+miR-345-3p-inhibitor group,with 15 rats in each group.Glucose and lipid metabolism indexes were detected in each group.FIns was detected by ELISA.The survival rate and body weight of fetal rats were compared in each group.The expression of Circ-PNPT1,miR-345-3p and FLOT2 mRNA in placenta was detected by qRT-PCR.The double luciferase reporter gene experiment verified the targeting relationship between miR-345-3p and Circ-PNPT1 and FLOT2.Western blot was used to detect the expression of FLOT2 protein in rat placenta.Results Compared with the NC group,the level of FPG,FIns,HOMA-IR,TC,TG,LDL-C,embryo weight,and the expressions of Circ-PNPT1,FLOT2 in GDM group increased,the level of HDL-C,embryo survival rate and the expression of miR-345-3p decreased(P<0.05).Compared with GDM group,the level of FPG,FIns,HOMA-IR,TC,TG,LDL-C,embryo weight,and the expression of FLOT2 in si-Circ-PNPT1 group decreased,the level of HDL-C,embryo survival rate and the expression of miR-345-3p increased(P<0.05);MiR-345-3p-inhibitor reversed the improvement of si-Circ-PNPT1 on GDM rats(P<0.05).Conclusions Knocking down Circ-PNPT1 can up-regulate miR-345-3p and down-regulate FLOT2 to improve glucose and lipid metabolism and offspring outcome in GDM rats.

Objective To explore and study the new nationwide centralized volume-based procurement model of Chinese patent medicines(CPM),aiming further to promote the normalization and institutionalization of such procurement practices.Methods This study conducts a retrospective analysis of the entire 2023 national CPM procurement process,comparing it with the 19-province alliance procurement,the national chemical drugs procurement,and the national insulin special procurement and highlighting its similarities and differences.Results In contrast to the 19-province alliance procurement,the national CPM alliance procurement introduced a daily average cost rule to reduce the price selection deviation.It also improved and optimized the criteria for qualification,bidding unit formation principles,selection rules,resurrection mechanisms,and principles for allocating procurement volumes under agreements.A comprehensive analysis of the results from two rounds of CPM procurement indicates statistically significant differences in resurrection rates,brand substitution rates,and reduction in selected prices,with the national procurement outperforming the 19-province alliance procurement.Compared with the national chemical drugs and special insulin procurements,this procurement distinctly showcases its unique characteristics.Conclusion The new mode of the national CPM alliance procurement is innovative and has contributed valuable experiences towards the sustained advancement of CPM procurement and establishing a medical insurance payment standard system.

Abstract Enhancing the health literacy of the entire population is a prerequisite for improving the health of the entire population, and since the health attitudes and behaviors formed during childhood and adolescence have a profound impact on the health patterns of adulthood, the enhancement of health literacy of children and adolescents is of particular importance. As the main place for children and adolescents to receive education, schools should better fulfil the function of education and promotion of health literacy. China has been carrying out the pilot and promotion of health promoting schools (HPS) since 1995, and is currently in the stage of comprehensive improvement of HPS construction. This paper introduces the background and characteristics of Health-Literate Schools (HeLit-Schools) in foreign countries and compares them with HPS in China, drawing on the advantages of HeLit-Schools to provide a new idea and a new way of thinking for the construction of HPS in China and for the practice of the "Healthy China Initiative".

Objective: To analyze the relationship between new surrogate marks of insulin resistance (IR) and bone mineral content (BMC) in adolescents, and predictive value of the new surrogate marks on low bone mass, so as to provide scientific basis for early identification and prevention of skeletal related diseases in adolescents. Methods: A total of 1 594 adolescents aged 12-18 years in Yinchuan City were selected by convenience sampling and stratified cluster random sampling from September 2017 to September 2020, and triglyceride and glucose index (TyG), triglyceride glucose-body mass index (TyG-BMI) and triglyceride/high density lipoprotein cholesterol (TG/HDL-C) were calculated as new simplified IR index. The correlation between different simplified IR indexes and BMC level was analyzed by partial correlation. Binary Logistic regression was used to analyze the relationship between IR index and low bone mass, and receiver operating characteristic (ROC) curve was constructed to analyze its evaluation effect on low bone mass. Results: After adjusting for confounding factors such as gender, age, smoking, drinking, family history of hypertension, systolic blood pressure (SBP) and diastolic blood pressure (DBP), the new surrogate marks of IR were positively correlated with BMC level (TyG: r =0.11, TyG-BMI: r =0.58, TG/HDL-C: r =0.21, P <0.01). After further adjustment of body mass index (BMI), fat mass (FM) and lean mass (LM), the relationship between IR indexes and BMC turned into negative correlation (TyG: r =-0.20, TyG-BMI: r =-0.18, TG/HDL-C: r=-0.14, P <0.01). After adjusting for confounding factors such as gender, age, smoking, drinking, family history of hypertension, SBP and DBP, Logistic regression results showed that the increase of TyG, TyG-BMI and TG/HDL-C levels reduced the possibility of low bone mass in adolescents (TyG: OR=0.63, 95%CI = 0.40-0.98, TyG-BMI: OR=0.94, 95%CI =0.93-0.96, TG/HDL-C: OR=0.31, 95%CI=0.17-0.58, P <0.01). After adjusting BMI, FM and LM, the above results were completely reversed. Girls with high TyG and TG/HDL-C levels were 4.95 and 4.38 times more likely to have low bone mass than those with low TyG and TG/HDL-C levels (TyG: OR=4.95, 95%CI =1.29- 18.95 , TG/HDL-C: OR=4.38, 95%CI=1.04-18.50, P <0.05). ROC curve showed that TyG-BMI had the best predictive value on low bone mass (AUC=0.80, 95% CI=0.77-0.83, P <0.01). Conclusion The new surrogate marks of IR in adolescents are negatively correlated with adolescent BMC, of which TyG-BMI is the best for assessing of low bone mass and can serving as a reliable indicator for early identification of low bone mass.
