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 analyse the clinical significance of selective single embryo transfer by time-lapse mo-nitoring(TLM)or conventional morphology assessment(CMA)in vitro fertilization/intracytoplasmic sperm in-jection and embryo transfer(IVF/ICSI-ET),and to initially explore the predictive value of Raman spectral analy-sis of embryo culture medium for clinical pregnancy rate.Methods:The study is a prospective randomized con-trolled clinical trial.We assigned 139 patients treated with IVF/ICSI-ET in Reproductive and Genetics Center of Suzhou Municipal Hospital from April 2019 to July 2020,which were randomly assigned to either the CMA or the TLM group.We performed selective single-embryo transfer(fresh cycle and FET)after selecting the optimal em-bryos with TLM or CMA respectively.If the patient's first embryo transfer was unsuccessful,a second one would be performed to compare the differences in the cumulative live birth rate of embryo transfer and other pregnancy outcomes between the two groups.Meanwhile,we collected 15 μl of embryo culture medium at day 3 after IVF/ISCI fertilization for Raman spectroscopy analysis.Results:There were no differences in cumulative live birth,cu-mulative clinical pregnancy,cumulative premature birth,cumulative early spontaneous abortion,cumulative ectopic pregnancy and LGA or SGA between TLM and CMA groups(P＞0.05).The Neonatal sex ratio in the TLM group was lower than that in the CMA group,but the difference was not significant(P＞0.05).Raman spectros-copy analysis of embryo culture medium predicted the clinical pregnancy rate with 67.21％accuracy.Conclu-sions:In young women with a good ovarian reserve,the advantage of using TLM to evaluate embryos is not obvi-ous,so we should remain vigilant that embryo selection based on morphokinetic parameters may affect the sex ratio.Raman spectroscopic analysis of embryo culture medium is not yet able to effectively predict the planting ability of embryos.

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.

Bone organoids can simulate the complex structure and function of the bone tissues, which makes them a frontier technology in organoid researches. Bone organoids show a tremendous potential of applications in bone disease modeling, bone injury repair, and medicine screening. Although advancements have been made so far in constructing bone organoids with functional structures like mineralization, bone marrow, trabecular bone, callus, woven bone, etc, the researches in this field are confronted with numerous challenges such as lack of standardized construction strategies and unified evaluation criteria, which limits their further promotion and application. To standardize researches in bone organoids, the Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, the Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, the Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and the Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine organized related experts to formulate Expert consensus on the construction, evaluation, and application of bone organoids ( version 2024) based on an evidence-based approach. A total of 17 recommendations were put forth, aiming to standardize researches and clinical applications of bone organoids and enhance their value in scientific research and clinical practice.

The mammalian target of rapamycin (mTOR) signaling pathway plays an important role in tumorigenesis, development of tumor and tumor therapy. Previous studies have reported on the abnormalities of mTOR signaling pathway leading to the development of a variety of malignant tumors and the antitumor efficacy of various mTOR inhibitors. However, multiple studies in recent years on the mechanisms of drug resistance in tumor therapy with chemotherapy or programmed death receptor 1 inhibitors have focused on the possibility that inhibition of mTOR signaling may be associated with tumor resistance to therapy. This article summarizes the physiological functions of mTOR signaling pathway and its regulatory mechanisms in tumorigenesis, and provides a review for its mechanism of action in tumor therapy sensitivity.

Objective:To introduce a novel risk factor for lumbar spondylolysis, the pedicle isthmus angle (PIA), and to explore its underlying mechanism and clinical relevance.Methods:A retrospective analysis of CT imaging data from young male patients with lumbar spondylolysis, admitted to the 960th Hospital of the Joint Logistic Support Force of the PLA between January 2018 and August 2023, was conducted. The study included 119 cases of unilateral spondylolysis and 339 cases of bilateral spondylolysis, with a mean age of 22.8±3.4 years (range 18-30 years). A control group of 458 patients with normal lumbar CT scans, presenting with low back pain, was also analyzed. Their mean age was 22.9±3.5 years (range 18-30 years). The PIA of the left and right sides of the L 3, L 4, and L 5 vertebrae in both the spondylolysis and control groups were measured using CT imaging. Differences in PIA measurements between the left and right sides, as well as between groups, were compared. Binary logistic regression analysis identified risk factors for lumbar spondylolysis. The receiver operating characteristic (ROC) curve and Youden index were used to determine the critical risk threshold for lumbar spondylolysis. Results:No significant differences were found between the spondylolysis and control groups in terms of gender, age, height, weight, or body mass index (BMI) ( P>0.05). Similarly, there was no significant difference in the left and right PIA measurements for the L 3, L 4, and L 5 vertebrae in either group ( P>0.05). The PIA of the L 3 and L 4 vertebrae was not significantly different between the groups (107.2°±3.5° vs. 107.1°±3.5°, t=0.270, P=0.787; 110.6°±3.5° vs. 110.5°±4.0°, t=0.441, P=0.659). However, the PIA of the L 5 vertebra was significantly larger in the spondylolysis group (117.7°±4.7°) compared to the control group (114.0°±4.9°) ( t=11.654, P<0.001). Logistic regression analysis identified an increased PIA at L 5 ( β=0.159, OR=1.172, P<0.001) as a risk factor for lumbar spondylolysis. According to the ROC curve and Youden index, the risk of lumbar spondylolysis increased substantially when the L 5 PIA exceeded 115.8°. The area under the curve (AUC) was 0.709, with a sensitivity of 0.670 and a specificity of 0.644. Conclusion:PIA is an objective and effective imaging parameter for predicting lumbar spondylolysis. It aids in understanding the pathophysiology of spondylolysis, identifying high-risk individuals, and informing prevention and treatment strategies for lumbar spondylolysis.

Objective To observe the effect of dapagliflozin on cardiac function in patients with heart failure after emergency percutaneous transluminal coronary intervention in acute ST segment elevation myocardial infarction. Methods A total of 100 patients with acute myocardial infarction underwent emergency PCI were randomly divided into study group (52 cases) and control group (48 cases). The study group was given dapagliflozin on the basis of standardized treatment of myocardial infarction, and the control group was given conventional treatment of myocardial infarction. Cardiac ultrasound related indexes[left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic volume (LVEDV)], plasma N-terminal brain natriuretic peptide (NT-proBNP) level, 6-minute walking test (6MWT) results. The incidence of adverse reactions and major cardiovascular adverse events (MACE) were compared between the two groups during follow-up. Results After 6 months of treatment, LVESD, LVEDD and LVEDV in the two groups were significantly lower than before treatment, and LVEF was significantly higher than before treatment (P < 0.05); the LVESD, LVEDD and LVEDV of the study group were significantly lower than those of the control group, and LVEF was significantly higher than that of the control group (P < 0.05). The NT-proBNP in the two groups was significantly lower than before treatment, and was significantly lower in the study group than that in the control group (P < 0.05). The 6MWT distance of the study group was significantly longer than that of the control group (P < 0.05). There was no significant difference in the incidence of adverse reactions and MACE between the two groups (P>0.05). Conclusion Dapagliflozin can improve cardiac function in patients with heart failure after emergency PCI of acute ST segment elevation myocardial infarction.

OBJECTIVE: To assess the efficacy on relieving pain and improving the range of motion of shoulder joint in post-stroke shoulder-hand syndrome of phlegm-stasis obstruction in treatment of the combined therapy of eye acupuncture, Tengliao (Chinese herbal warm dressing technique) and rehabilitation training (eye acupuncture + Tengliao + rehabilitation) as compared with the combined treatment of Tengliao and rehabilitation training (Tengliao + rehabilitation) and the simple rehabilitation training (rehabilitation). METHODS: A total of 356 patients with post-stroke shoulder-hand syndrome of phlegm-stasis obstruction were randomized into an eye acupuncture + Tengliao + rehabilitation group (group A, 122 cases, 2 cases dropped off), a Tengliao + rehabilitation group (group B, 120 cases, 3 cases dropped off) and a rehabilitation group (group C, 114 cases, 1 case dropped off). In the group C, the basic treatment was combined with routine rehabilitation training. In the group B, on the base of the treatment as the group C, Tengliao was exerted. A medical bag composed of over 20 Chinese herbal materials was heated and dressed at the affected area, 30 min each time, 5 times weekly. In the group A, besides the treatment as the group B, eye acupuncture was applied to heart region, kidney region, upper jiao region and lower jiao region, 30 min each time, 5 times weekly. The treatment lasted 28 days in all of three groups. Separately, before treatment, in 7, 14, 21 and 28 days of treatment, as well as in 14 days after treatment of follow-up, the score of visual analogue scale (VAS) for pain, the score of guides to evaluation of permanent impairment (GEPI) and the score of National Institutes of Health stroke scale (NIHSS) were observed in each group. RESULTS: The scores of VAS, GEPI and NIHSS were all improved with the treatment lasting in the three groups (P<0.000 1). In 7, 14, 21 and 28 days of treatment and in follow-up as well, VAS scores in the group A were all lower than the group C (P<0.05). After 14 days of treatment, GEPI score showed increasing trend, while NIHSS score showed decreasing trend in the group A compared with the group B. Before treatment, GEPI score was lower and NIHSS score was higher in the group A compared with the group C (P<0.05). It was suggested that the illness was slightly serious in the group A. After propensity score matching, in 14, 21 and 28 days as well as in follow-up, GEPI scores in the group A were higher than the group C respectively (P<0.05). Regarding NIHSS score at each time point, the difference had no statistical significance between the group A and the group C (P>0.05). CONCLUSION The combined therapy of eye acupuncture, Tengliao and rehabilitation training obtains a better efficacy on post-stroke shoulder-hand syndrome of phlegm-stasis obstruction as compared with rehabilitation training.
