Objective: To explore the potential category patterns of risk prevention and control behaviors of HIV infection among young students who have sex with men (MSM) and their impact on HIV infection and late detection, aiming to optimize intervention strategies. Methods: From September 2017 to December 2024, a total of 1 637 MSM young students in Tianjin were recruited through both online and offline channels. Latent class analysis was applied to classify 11 HIV risk prevention and control behaviors [condom use during the most recent anal sex in the past 6 months, consistent condom use, use of water based lubricants, abstinence from recreational drugs, regular on site professional testing, fixed sexual partners, partner testing, awareness of partner s HIV testing results, testing before sexual activity, nucleic acid testing, and use of pre exposure prophylaxis (PrEP) or post exposure prophylaxis (PEP)]. Multivariate Logistic regression analyzed associations between demographic characteristics/intervention services factors and latent classes. Differences in HIV infection and late detection across behavior patterns were compared. Results: HIV risk prevention and control behaviors among MSM students were classified into three latent classes:condom dependent group (38.42%), low prevention group (27.73%), and comprehensive prevention group (33.85%). Students who received condom promotion/testing services were more likely to belong to the comprehensive prevention group ( OR =5.58), while those who received peer education were less likely to the comprehensive prevention group ( OR =0.43) (both P <0.01). Among the MSM student population, the HIV infection rate was 4.83%, with 2.26% of cases detected late. The HIV infection rate (1.45%) and late detection proportion (0.82%) in the comprehensive prevention group were lower than those in the low prevention group (7.89% and 3.83%, respectively) ( χ 2=16.20, 7.31, both P <0.01). Conclusions HIV risk prevention and control behaviors among MSM young students exhibit significant heterogeneity. Comprehensive prevention strategies can effectively reduce HIV infection and late detection risks. It is necessary to optimize peer education content and improve the accessibility of diversified prevention measures such as PrEP/PEP to enhance HIV prevention and control.

Objective:To summarize the characteristics of color doppler flow imaging (CDFI) of ocular toxocariasis (OT) in children.Methods:A retrospective clinical study. From July 2014 to June 2020, 61 OT patients with 61 eyes diagnosed through clinical and laboratory testing in the Department of Ophthalmology of Beijing Tongren Hospital of Capital Medical University were included in the study. There were 45 males with 45 eyes and 16 females with 16 eye (male: female=2.81:1). Age were (6.93±2.50) years. The right eye and left eye were 29 and 32 eyes, respectively. Both eyes of the patient underwent two-dimensional ultrasound and CDFI examination. Two dimensional ultrasound was used to estimate the axial length (AL) of the affected eyes and healthy eyes on the opposite side. Among them, 52 cases were measured for AL using optical biometry and/or A-mode ultrasound. Vitreoretinal surgery was performed within one week after ultrasound examination. Two-dimensional ultrasound was used to observe the morphology of vitreous opacity, its connection to the eyeball wall, and whether posterior vitreous detachment and retinal detachment have occurred. CDFI examination was used to observe the presence of blood flow signals on the pathological membrane. The detection rates of different forms of vitreous opacity and traction retinal detachment were calculated. The location of proliferative lesions in the eye was analyzed. Paired t-test was performed to compare the AL of the affected eye and the healthy eye on the opposite side. Perform Kappa consistency test on the location of proliferative lesions was used during CDFI examination and vitreoretinal surgery. Results:All affected eyes have varying degrees of vitreous opacity. Among them, 23 eyes (37.7%, 23/61) showed typical "Christmas tree" like turbidity; 27 eyes (44.3%, 27/61) had clustered and striped echoes; 9 eyes (14.8%, 9/61) had weak punctate and strip echoes. Two eyes (3.3%, 2/61) showed a large amount of dense punctate and strip-shaped echoes. There were 50 eyes (82.0%, 50/61) with traction retinal detachment, of which 46 eyes (92.0%, 46/50) had visible blood flow signals on the detached retina, and the remaining 4 eyes (8.0%, 4/50) had no blood flow signals. During CDFI and surgery, there were 5 (8.2%, 5/61) and 4 (6.6%, 4/61) eyes with visible proliferative lesions in the periphery, respectively; 18 (29.5%, 18/61) and 14 (23.0%, 14/61) eyes were distributed in the posterior pole, respectively; there were 38 (62.3%, 38/61) and 43 (70.5%, 43/61) eyes with both peripheral and posterior polar regions, respectively. The consistency between CDFI and surgery in detecting the location of proliferative lesions was good ( κ=0.832, 95% confidence interval 0.691-0.973, P<0.001). The two-dimensional ultrasound measurement results showed that the AL of the affected eye was shorter than that of the contralateral healthy eye in 46 cases (75.4%, 46/61). Among the 52 patients who underwent AL biometry, the AL of the affected eye was shorter than that of the contralateral healthy eye by (0.63±0.68) mm, and the difference was statistically significant ( t=-6.738, P<0.05). Conclusions:CDFI can clearly display various intraocular lesions (vitreous opacity and traction retinal detachment) and eyeball sizes in children with OT. Vitreous opacity is often manifested as "Christmas tree" like, clustered, strip-shaped.

ObjectiveTo investigate the effects of maltol aluminum exposure on miR-193a-3p, demethylase AlkB homolog 5 (ALKBH5), phosphatase and tensin homolog deleted on chromosome ten (PTEN) and protein kinase B (AKT), and whether miR-193a-3p is involved in aluminum-induced cognitive impairment by regulating ALKBH5/PTEN/AKT signaling pathway. Methods Specific pathogen-free male SD rats were randomly divided into control group and low-, medium- and high- dose groups according to their body weight, with eight rats in each group. Rats in the low-, medium-, and high- dose groups were intraperitoneally injected with maltol aluminum solution at concentrations of 10.00, 20.00, and 40.00 μmol/kg body weight, respectively, while the rats in control group were given an equal volume of 0.9% sodium chloride solution. Rats were injected for five days every week for three months. After injection, the novel object recognized test was used to assess the learning and memory ability of the rats. The relative expression of miR-193a-3p and B-cell lymphocytoma-2 (Bcl-2), Bcl-2 associated X protein (Bax) and cysteine aspartate protease-3 (Caspase-3) mRNA in rat hippocampus was detected using the real-time quantitative polymerase chain reaction. The relative protein expression of ALKBH5, PTEN, and AKT2 in the rat hippocampus was detected using Western blot. Results The discrimination index and the preference index of the new object recognition test of the rats in high-dose group were lower than those in control group and low-dose group (all P<0.05). The relative expression of miR-193a-3p and Bcl-2 mRNA in the hippocampus of the rats in high-dose group was lower than those in control group and low-dose group (all P<0.05). The relative mRNA expression of Bax in the high-dose group was higher than those in the control group and low-dose group (both P<0.05). The relative mRNA expression of Caspase-3 of the rats in the high-dose group was higher than that in the other three groups (both P<0.05). The relative protein expression of ALKBH5 in the hippocampus of the rats in the high-dose group was lower than that in the control group (P<0.05). The relative expression of PTEN protein was higher than those in the control group and low-dose group (both P<0.05). The relative protein expression of AKT2 was lower than those in the control group and low-dose group (both P<0.05). Conclusion Sub-chronic aluminum exposure can inhibit the expression of miR-193a-3p in the hippocampus of rats, which may disrupt the ALKBH5/PTEN/AKT pathway and affect normal neuronal homeostasis and cellular function. This pathway may play an important role in aluminum-induced cognitive impairment.

BACKGROUND:Recent studies have shown that research on naringin anti-osteoporosis mostly stays in in vitro and in vivo experiments.Understanding the mechanism of related signaling pathways and the expression of related proteins and some specific genes is an important way to deeply understand naringin anti-osteoporosis.At present,traditional Chinese medicine has been confirmed to have a significant role in anti-osteoporosis.Naringin is one of the main active ingredients in Rhizoma Drynariae.Its effectiveness and mechanism of action against osteoporosis have been gradually recognized by scholars,and its clinical and basic research has been gradually emphasized. OBJECTIVE:To analyze and summarize the research progress of naringin in anti-osteoporosis in vitro and in vivo,thereby providing some ideas for the next step to study its related mechanism of action. METHODS:The relevant literatures included in CNKI and PubMed database were searched with the Chinese search terms of"naringin,osteoporosis,traditional Chinese medicine compound,pathogenesis,signaling pathway,bone marrow mesenchymal stem cells,osteoblasts,osteoclasts"in Chinese and English,respectively.The corresponding criteria were established according to the research needs,and finally 69 articles were included for review. RESULTS AND CONCLUSION:Naringin blocks the increase in the number of osteoclasts and adipocytes,the decrease in the number of osteocytes and osteocalcin(+)cells induced by fructose-rich diet,and promotes the secretion of Sema3A from osteoblasts and osteocytes,thereby enhancing local bone formation and inhibiting osteoclast production by activating the Wnt/β-catenin pathway.Naringin is an important way to induce autophagy of osteoblasts,but autophagy-related proteins participate in osteoblast differentiation and bone formation.Lack of autophagy in osteoblasts reduces mineralization and leads to an imbalance in the number of osteoblasts and osteoclasts,which results in bone loss and decreased bone density.The composite scaffold loaded with naringin can be used as a necessary carrier for bone defect repair and has excellent bone repair properties.Naringin can also accelerate the growth of new bone tissue by increasing the local contents of bone morphogenetic protein 2 and vascular endothelial growth factor.Naringin can regulate bone metabolism and inhibit oxidative stress via ERK,PI3K/Akt and Wnt signaling pathways to improve osteoporosis,which can play a good role in preventing and controlling the disease.However,the depth and breadth of the relevant research is insufficient.Based on the mechanism of the current study,we should investigate the specific mechanisms by which naringin regulates different pathways and inter-pathway interactions in the future,which will be beneficial to the multifaceted development of naringin used in the treatment of osteoporosis..

Objective To observe the value of 18F-fluoro-dihydroxy-phenylalanine(18F-FDOPA)PET/CT for evaluating the efficacy of radiochemotherapy for advanced glioma.Methods Data of 84 patients with advanced glioma who received precision radiotherapy combined with synchronous chemotherapy were retrospectively analyzed.The patients were divided into effective group(complete remission+partial remission+stable disease,n=60)and ineffective group(progressive disease,n=24)according to the efficacy of radiochemotherapy.18F-FDOPA PET/CT metabolic parameters of tumors,including tumor metabolic tumor volume(MTV),maximum standard uptake value(SUVmax)and mean standard uptake value(SUVmean)were compared between groups,also before and after radiochemotherapy within groups.Spearman correlation analysis was used to observe the correlations of metabolic parameters and the efficacy of radiochemotherapy.Results After radiochemotherapy,MTV,SUVmax and SUVmean of tumors in effective group were lower than those of tumors in ineffective group(all P＜0.05).Significant differences of metabolic parameters were found before and after radiochemotherapy in effective group(all P＜0.05).MTV,SUVmax and SUVmean of advanced glioma were negatively correlated with the efficacy of radiochemotherapy(r=-0.63,-0.52,-0.50,P＜0.001,P=0.007,P=0.010).Conclusion 18F-FDOPA PET/CT was helpful for evaluating the efficacy of radiochemotherapy for advanced glioma.

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.

ObjectiveTo investigate the potential effect of ursodeoxycholic acid （UDCA） in the prevention and treatment of COVID-19 in patients with chronic hepatitis B. MethodsClinical data were collected from 324 patients with chronic hepatitis B who were treated in Beijing Ditan Hospital， Capital Medical University， from January to December 2022， and according to whether UDCA was administered， they were divided into UDCA group and control group. The propensity score matching （PSM） method was used to balance the confounding factors such as age， sex， and chronic complications， and the two groups were compared in terms of SARS-CoV-2 infection rate， symptoms， and recovery time after COVID-19. The two groups were also compared in terms of related laboratory markers （white blood cell count ［WBC］， hemoglobin ［Hb］， platelet count ［PLT］， alanine aminotransferase ［ALT］， aspartate aminotransferase ［AST］， albumin ［Alb］， alkaline phosphatase ［ALP］， total bilirubin ［TBil］， triglyceride ［TG］， and total cholesterol ［TC］）， vaccination， and the incidence rate of liver disease symptoms after COVID-19. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of data with skewed distribution between the two groups； the chi-square test and the continuously corrected chi-square test were used for comparison of categorical data between two groups. The binary Logistic regression model was used for univariate and multivariate analyses to investigate the influencing factors for COVID-19 after matching. ResultsThere were 87 patients in the UDCA group and 237 patients in the control group， and after PSM， there were 78 patients in the UDCA group and 137 patients in the control group， with good balance between the two groups. There was a significant difference in SARS-CoV-2 infection rate between the UDCA group and the control group ［82.1% （64/78） vs 95.6% （131/137）， χ²=10.847， P=0.001］. After COVID-19， compared with the control group， the UDCA group had a significantly lower proportion of the patients with chill （10.9% vs 38.9%， χ²=16.124， P<0.001） and cough （56.3% vs 74.8%， χ²=6.889， P=0.009）. There was a significant difference between the UDCA group and the control group in the proportion of the patients with a recovery time of ≤7 days after COVID-19 （79.7% vs 61.1%， χ²=6.760， P=0.009）. Both univariate and multivariate logistic regression analyses showed that UDCA was an independent influencing factor for COVID-19 （odds ratio=0.21 and 0.17， both P<0.05）. ConclusionUDCA is an protective factor against COVID-19 in patients with chronic hepatitis B and can alleviate related symptoms to some extent and shorten the recovery time， and therefore， it has an important value in the prevention and treatment of COVID-19.

Objective To explore the effect of endophytes on Nanyang Mugwort by analyzing the diversity of endophytic flora and its correlation with the content of key secondary metabolites in three compartments of Nanyang Mugwort,and the effect of medicinal material quality.Methods In this study,high-throughput sequencing and high-performance liquid chromatography(HPLC)were carried out to determine the distribution endophytes and key secondary metabolites in three compartments of Nanyang Mugwort respectively.The endophytic communities that were significantly correlated with key secondary metabolites were screened by Pearson correlation analysis.Results We found endophytic diversity and composition showed compartment specificity,and bacterial and fungal alpha diversity values(Chao and Ace)in the root compartment were significantly higher than that of leaf and stem.Linear discriminant analysis efect size(LEfSe)analyses identified some potential microbial biomarkers,such as Rhizobium,Streptomyce,Xanthomonadaceae,and Sordariomycetes.Pearson correlation analysis showed that endophytes(such as Rhizobium,Pseudomonas,Flavobacterium,Streptomyces Aspergillus,and Olpidium)were significantly correlated with contents of some phenylpropanoid and flavonoid metabolites in our study(P<0.05).Conclusion In this study,some endophytic communities with significant correlation between key secondary metabolites of Nanyang Mugwort were identified,which provided valuable information to guide the isolation of endophytic strains related to key secondary metabolites and improve the quality of Nanyang Mugwort.
