Hyperparathyroidism-jaw tumor syndrome (HPT-JT) is a rare familial autosomal dominant genetic disease with primary hyperparathyroidism, jaw tumors, kidney tumors and uterine tumors caused by cell division cycle 73 (CDC73) germline mutations. A 42-year-old male patient was admitted for pancreatitis and further examination revealed elevated PTH at 54.00pmol/L and a history of jaw tumors. This patient was diagnosed as HPT-JT finally and underwent upper right, lower right, and upper left parathyroid glands resection and genetic testing. Postoperative pathology revealed that atypical adenomatous nodules of parathyroid glands with extensive atypia and nucleus division and parathyroid hyperplasia and whole exome sequencing suggested that the CDC73 mutation.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Objective　To analyse the crude detection rate and trends of newly detected HIV/AIDS cases in medical institutions in China from 2017 to 2023, and to provide a reference for optimizing HIV testing strategies in medical institutions. Methods　Data on HIV testing and newly reported HIV/AIDS cases were analysed using data from the Comprehensive AIDS Prevention and Control Information System of the China Information System for Disease Control and Prevention for the period from 2017 to 2023. HIV testing in medical institutions includes patients tested preoperatively, those tested before transfusion, those tested in sexually transmitted disease (STD) clinics, prenatal care clinics, and other types of patients. Descriptive statistical analysis and χ2 test were performed using SAS 9.4 software. Joinpoint regression was performed using Joinpoint 4.9.0 software to analyse trends of the crude detection rates over time. Results　From 2017 to 2023, the person-times of HIV tests in medical institutions increased from 143 million to 255 million, with an increase of 78.07%. The number of newly detected HIV/AIDS cases increased from 74 000 to 88 000 and then declined to 69 000. The crude detection rate of new HIV/AIDS cases declined from 5.18/10 000 to 2.71/10 000, showed a declining trend, the mean annual percentage change was -9.99%(P<0.001). The crude detection rate of new HIV/AIDS cases in STD clinics was the highest among all types of clinic visits (12.79/10 000-24.47/10 000), and the crude detection rate of new cases among all types of clinic visits showed a decreasing trend(P<0.05). Among different medical institutions, general hospitals were the most important source of the number of tests and the number of newly detected HIV/AIDS cases, accounting for more than 62.93% and 62.68%, respectively. Specialised medical institutions had the highest crude detection rate of new cases, which was maintained at more than 5.13/10 000. The crude detection rate of new cases for all four types of medical institutions, except for primary medical institutions, showed a decreasing trend (P<0.05). Conclusions　The detection rate of new cases in medical institutions showed a decreasing trend in 2017-2023, and the efficiency of STD clinics testing and detection was higher among all types of attendees. General hospitals are the main source of new cases detection, and testing in specialised medical institutions is more efficient. Testing should be strengthened in key groups of patients and in key medical institutions.

Objective:To explore the effects of human chorionic gonadotropin (hCG), progesterone as well as the change of estradiol 12 h after hCG trigger on the outcomes of in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET). Methods:A retrospective study was conducted at the Center for Reproduction and Genetics of the Affiliated Suzhou Hospital of Nanjing Medical University. A total of 2 506 patients received IVF/ICSI-ET treatment with gonadotropin-releasing hormone agonist (GnRH-a) protocol from March 2015 to June 2020 were selected. With Spearman rank correlation analysis and path analysis, we explore the relationship among the changes of these hormones and the baseline characteristic of patients, as well as the relationship among the changes of these hormones and the outcomes of IVF treatment.Results:The increase of hCG was accompanied by the rise of progesterone and the decline of estradiol change rate ( r=0.094, P<0.001; r=-0.093, P<0.001). Meanwhile the rise of progesterone was accompanied by the decline of estradiol change rate ( r=-0.089, P<0.001). The dosage of hCG trigger was directly positively correlated to hCG level after hCG trigger, path coefficients (PC) was 0.307 ( P<0.001). Body mass index (BMI) was directly negatively correlated to hCG level and progesterone level after hCG trigger (PC=-0.434, P<0.001; PC=-0.154, P<0.001), whereas positively correlated to estradiol change rate (PC=0.097, P<0.001). Meanwhile the duration and dosage of gonadotropin (Gn) used were positively correlated to progesterone level after hCG trigger (PC=0.102, P<0.001; PC=0.080, P=0.030). hCG level and progesterone level after hCG trigger had positive correlation to oocyte retrieved rate (PC=0.098, P<0.001; PC=0.080, P<0.001). While estradiol change rate was not correlated to oocyte retrieved rate ( P>0.05). Progesterone level on hCG trigger day negatively related to normal fertilization rate (PC=-0.050, P=0.039). hCG level, progesterone level and estradiol change rate after hCG trigger had no correlation with high-quality embryo rate, clinical pregnancy rate and live birth rate (all P>0.05). Conclusion:Oocyte retrieved rate was positively affected by hCG level and progesterone level 12 h after hCG trigger. While normal fertilization rate, high-quality embryo rate, clinical pregnancy rate and live birth rate were not affected by the change of hormones level 12 h after hCG trigger. Therefore we should pay attention to hCG level and progesterone level 12 h after hCG trigger.

Objective:To explore the causal relationship between social activity and depressive symptoms in the elderly, and to provide a reference for preventing and interventing depressive symptoms in the elderly.Methods:Data were sourced from the China Health and Retirement Longitudinal Study (CHARLS) program, involving 3 164 elderly individuals aged≥60 years with data collected in two measurements, in 2015 (T1) and 2018 (T2). The sample included 1 240 males and 1 924 females aged (71±7) years. Social activities were assessed by constructing a social activity index from the 11 social activities included in the CHARLS questionnaire and the frequency of their activities. The depressive symptoms were assessed using the short version of the Center for Epidemiological Studies Depression Scale (the 10-item Center for Epidemiological Studies Depression Scale, CESD-10). A mixed-design ANOVA was used to explore the trends in social activity and depressive symptoms over time and across genders in the elderly adults. Pearson correlation analysis was used to investigate whether social activity and depressive symptoms in the elderly met the criteria for simultaneous and sequential correlations, followed by a cross-lagged model to analyze the causal temporal or mutual prediction between social activeness and depressive symptoms over a 3-year intervals.Results:The social activity of elderly men at T2 was significantly lower than at T1 ( F=21.00, P<0.001), while no significant difference observed in elderly women ( F=0.31, P<0.001). At both T1 and T2, elderly men scored higher in social activity than elderly women [T1: 2.93±2.98 vs 2.55±2.65,T2: 2.28±2.49 vs 2.24±2.43); F=43.60, 11.24, both P<0.01]. Depressive symptoms at T2 were higher than at T1 for both elderly men and elderly women ((male: 1.90±6.10 vs 21.52±6.08, female: 23.84±6.54 vs 23.07±6.44); F=5.20, 32.77, both P<0.05). Elderly men scored lower than elderly women on depression symptoms at both T1 and T2 (T1: F=45.74, P<0.001; T2: F=69.96, P<0.001). Pearson correlation analysis showed a negative correlation between social activity and depressive symptoms at both measurement points (T1: r=-0.329, P<0.01; T2: r=-0.343, P<0.01), and a positive correlation across T1 and T2 ( r=0.391, 0.573; both P<0.01), meeting the criteria for simultaneous and sequential correlations, and supporting the basic assumptions of cross-lagged design. Cross-lagged analysis revealed that T1 social activity negatively predicted T2 depressive symptoms (β=-0.128, P<0.001), and T1 depressive symptoms negatively predicted T2 social activity (β=-0.202, P<0.001). Conclusion:There is a bidirectional predictive relationship between social activity and depression symptoms in the elderly. Depression symptoms lead to a decrease in social activity, and a decrease in social activity predicts an exacerbation of depression in the elderly.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Lumbar spondylolysis refers to the bone injury between the upper and lower articular processes and the transition zone of the transverse process of the unilateral or bilateral pedicle of the lumbar spine, being a common cause of low back pain in patients that seriously affects their quality of life. The mechanism of the occurrence and development of lumbar spondylolysis is complex, and long-term stress wear and sudden damage with an external force are the main causes. At the same time, risk factors related to spinal anatomy are important causes of lumbar spondylolysis. A full understanding of the pathogenesis of lumbar spondylolysis, early identification of high-risk groups, and active preventive measures can reduce its incidence. For this purpose, the authors reviewed the research progress in risk factors related to the spinal anatomy of lumbar spondylolysis from three aspects including genetical susceptibility, local anatomy and overall spine-pelvic sequence, so as to provide references for the prevention and treatment of spondylolysis.
