Objective: To explore the related factors of college students social network addiction based on problem behavior theory, so as to provide a basis for improving social networking addiction in this population. Methods: From May to June 2023, a method combining convenient sampling and cluster random sampling was used to select 1 768 college students from five universities in Shanghai for a questionnaire survey on social networking addiction, self esteem, loneliness, depressive symptoms, social support, interpersonal needs, sense of distress and frustration; at the same time, the physical exercise, smoking and drinking of college students were investigated. Multivariate Logistic regression analysis was applied to explore the association between the three systems of the problem behavior theory (personality, behavior, and social environment) and social networking addiction among college students. Results: The score on the Social Network Addiction Tendency Scale was (21.08±6.29) among college students, and the detection rate of social networking addiction was 66.29%. After adjusting for gender, family economic status, parental divorce status, and whether being an only child, multivariate Logistic regression analysis showed that in the personality system, higher loneliness ( OR =1.66) and higher depressive symptoms ( OR =2.18) were associated with increased risk of social networking addiction among college students; in the behavior system, alcohol consumption ( OR =1.42) was associated with higher risk of soical networking addiction compared to non drinkers; and in the social environment system, low social support ( OR =1.43) was associated with increased risk of social networking addiction (all P <0.05). Conclusions The rate of social networking addiction among college students is relatively high, and the systems of personality, behavior, and social environment are all related to social network addiction. Providing social support, cultivating healthy lifestyle habits, and increasing interpersonal interactions may help reduce excessive dependence on social networking among college students.

Objective To investigate the expression of PROM2,RALY and Rab15 in non-small cell lung cancer(NSCLC)and the predictive value for the development of bone metastasis in NSCLC.Methods One hundred and thirty four patients diagnosed with NSCLC in our hospital from Mar 2016 to Feb 2022 were retrospectively analyzed.Patients were divided into bone metastasis(BM)and non-bone metastasis(NBM)groups based on the occurrence of bone metastasis during follow-up.Immunohistochemistry was used to detect the expression of PROM2,RALY,and Rab15 in cancer tissues.The relationship between the expression of these markers and bone metastasis was analyzed,and Cox regression was used to identify risk factors for bone metastasis in NSCLC patients.Results During the follow-up period,43 patients with NSCLC developed bone metastases.Patients with bone metastases had higher age,BMI,percentage of adenocarcinoma,and positive expression of PROM2,RALY and Rab15 than those without bone metastases(P＜0.05).Multifactorial Cox analysis showed that age,type of pathology,ECOG,and the positive PROM2 expression were significant risk factors for bone metastases in NSCLC patients(P＜0.05).Among patients with bone metastases,those with positive PROM2 expression had a shorter median bone metastasis-free survival time compared to PROM2-negative patients(P＜0.05).Conclusion PROM2 positive expression is an independent risk factor for bone metastasis in NSCLC patients,and is closely related to their prognosis.

BACKGROUND: Early control of low-density lipoprotein cholesterol (LDL-C) is crucial for reducing the progress of cardiovascular disease. However, its additional role to the risk of primary osteoporosis in men with coronary heart disease was inconclusive. Our study aims to determine the association of LDL-C and its trajectories for osteoporosis risk in the middle-aged and aged men of China. METHODS: The retrospective cohort study of 1546 men aged 69.74 ± 11.30 years conducted in Beijing, China from 2015 to 2022. And the incidence of primary osteoporosis was annually recorded. LDL-C trajectories were further identified by latent class growth model using repeated measurements of LDL-C. The association of baseline LDL-C for osteoporosis was estimated using hazard ratio (HR) with 95% CI in Cox proportional hazard model, while mean level and trajectories of LDL-C for osteoporosis were evaluated using odds ratio (OR) with 95% CI in logistic regression model. RESULTS: During the median 6.2-year follow-up period, 70 men developed primary osteoporosis. The higher level of baseline LDL-C (HR = 1.539, 95% CI: 1.012-2.342) and mean LDL-C (OR = 2.190, 95% CI: 1.443-3.324) were associated with higher risk of osteoporosis in men with coronary heart disease after adjusted for covariates. Compared with those in the LDL-C trajectory of low-stable decrease, participants with medium-fluctuant trajectory, whose longitudinal LDL-C started with a medium LDL-C level and appeared an increase and then decrease, were negatively associated with osteoporosis risk (OR = 2.451, 95% CI: 1.152-5.216). And participants with initially high LDL-C level and then a rapid decrease demonstrated a tendency towards reduced risk (OR = 0.718, 95% CI: 0.212-2.437). CONCLUSIONS Elevated LDL-C level and its long-term fluctuation may increase the risk of primary osteoporosis in men. Early controlling a stable level of LDL-C is also essential for bone health.

OBJECTIVE: To preliminarily investigate the effect of buccal acupuncture therapy on ameliorating postoperative pain and enhancing recovery quality among patients undergoing radical resection of gastrointestinal cancers. METHODS: Fifty-two participants were randomized at a 1:1 ratio to either the buccal acupuncture or the control group. The acupuncture protocol entailed targeting 5 predetermined acupoints [CA-2 (Upper jiao), CA-3 (Middle jiao), CA-4 (Lower jiao), CA-6 (back), and CA-7 (waist) and two adjustable acupoints [CA-1 (head) and CA-8 (sacrum)] on each side of the face. The outcomes included the Numeric Rating Scale (NRS) scores for each day within 7 days postoperatively, 15-Item Quality of Recovery Scale (QoR-15) scores, analgesics consumption during and after surgery, incidences of postoperative nausea and vomiting, and perioperative levels of interleukin-6 and glucose. Adverse events related to acupuncture were recorded. RESULTS: Of the initial 52 participants, 46 completed the study and were included in the analysis. Findings indicated that the buccal acupuncture group experienced significantly reduced resting NRS scores in post-anesthesia care unit and throughout the postoperative phase (P=0.001 and P=0.003, respectively), along with enhanced QoR-15 scores on the 3rd postoperative day (P=0.008), compared to the control group. No notable differences were identified in the remaining indicators (P>0.05). CONCLUSION Buccal acupuncture therapy demonstrated significant effectiveness in reducing postoperative pain and improving recovery quality for patients undergoing radical resection of gastrointestinal cancers, presenting a viable intervention without associated adverse outcomes.

Background: Maturity-onset diabetes of the young (MODY) due to variants of hepatocyte nuclear factor 1-beta (HNF1β) (MODY5) has not been well studied in the Chinese population. This study aimed to estimate its prevalence and evaluate the application of a clinical screening method (Faguer score) in Chinese early-onset diabetes (EOD) patients. Methods: Among 679 EOD patients clinically diagnosed with type 2 diabetes mellitus (age at diagnosis ≤40 years), the exons of HNF1β were sequenced. Functional impact of rare variants was evaluated using a dual-luciferase reporter system. Faguer scores ≥8 prompted multiplex ligation-dependent probe amplification (MLPA) for large deletions. Pathogenicity of HNF1β variants was assessed following the American College of Medical Genetics and Genomics (ACMG) guidelines. Results: Two rare HNF1β missense mutations (E105K and G454R) were identified by sequencing in five patients, showing functional impact in vitro. Another patient was found to have a whole-gene deletion by MLPA in 22 patients with the Faguer score above 8. Following ACMG guidelines, six patients carrying pathogenic or likely pathogenic variant were diagnosed with MODY5. The estimated prevalence of MODY5 in Chinese EOD patients was approximately 0.9% or higher. Conclusion MODY5 is not uncommon in China. The Faguer score is helpful in deciding whether to perform MLPA analysis on patients with negative sequencing results.

Objective To investigate the expression of adenosine A3 receptor(ADORA3)in human glioma and its effects on prognosis and epithelial-mesenchymal transition.Methods The mRNA expression data and corresponding clinical information of ADORA3 were obtained from TCGA,CGGA,Rembrandt,Gravendeel and Gill databases,and the effects of ADORA3 expression on the prognosis of glioma patients and the process of epithelial-mesenchymal transition were analyzed.The surgically resected glioma samples of 35 cases,along with non-tumor brain tissues of 7 cases obtained from decompression surgery for severe craniocerebral injury were collected in the Department of Neurosurgery at Renmin Hospital of Wuhan University from July 2023 to April 2024,and the ADORA3 expression was detected by immunohistochemical staining.Glioblastoma multiforme(GBM)cells of U87 and U251 were transfected with NcRNA and SiRNA,respectively,as the control group and the knockdown group,and the effects of ADORA3 on cell invasion ability and epithelial-mesenchymal transition related proteins were analyzed by Transwell and Western blot.Results Bioinformatics analysis and immunohistochemical staining showed that the expression level of ADORA3 in human glioma tissues was significantly higher than that in non-tumor brain tissues(P<0.05),and the expression of ADORA3 was associated with glioma WHO grading(P<0.05).Kaplan-Meier survival curve analysis in TCGA,CGGA,Rembrandt and Gravendeel databases showed that the overall survival rate of patients with high ADORA3 expression was significantly lower than that of patients with low ADORA3 expression(P<0.001);and Cox regression analysis showed that high expression of ADORA3 was an independent risk factor for poor prognosis in patients with glioma(P<0.05);the expression level of ADORA3 in the mesenchymal type of GBM patients was significantly higher than that of the classical type and the proneural type;furthermore,ADORA3 showed significant correlations with epithelial-mesenchymal transition related markers of Vimentin,SNAI1,SNAI2,TWIST1,TWIST2,MMP2,CD44,and FN1.The knockdown of ADORA3 in vitro reduced the cell invasive ability,decreased the expression levels of MMP2,Vimentin,and SNAI1 proteins,and increased the expression of E-cadherin,with statistically significant differences(P<0.05).Conclusion ADORA3 is highly expressed in glioma,which can promote the process of epithelial-mesenchymal transition in patients,and serve as an independent risk factor for poor prognosis.

Objective To explore the influencing factors of intestinal obstruction(IO)in patients with laparoscopic radical resection of colorectal cancer(LRRCC).Methods From March 31,2021 to March 31,2024,clinical data of 389 patients with colorectal cancer(CRC)were retrospectively selected.According to whether IO occurred during their postoperative hospitalization,they were divided into the IO group with IO(68 cases)and the non-IO group without IO(321 cases).The clinical data of IO group and non-IO group were compared and multivariate Logistic regression analysis was used to study the influencing factors of IO in CRC patients undergoing LRRCC.Results The proportions of patients with TNM stage Ⅲ,lymph node metastasis,preoperative anemia,preoperative hypoproteinemia,history of abdominal surgery,preoperative IO,intraoperative fistula,LRRCC with left hemicolectomy(LH),LRRCC with right hemicolectomy(RH),and postoperative abdominal infection in the IO group were higher than those in the non-IO group,the differences were statistically significant(P<0.05).Multivariate Logistic regression analysis showed that TNM stage Ⅲ(OR＾=1.872,95%CI:1.253～2.798),lymph node metastasis(OR＾=1.808,95%CI:1.181～2.766),preoperative anemia(OR＾=1.900,95%CI:1.051～3.435),preoperative hypoproteinemia(OR＾=1.642,95%CI:1.143～2.360),history of abdominal surgery(OR＾=1.704,95%CI:1.118～2.597),preoperative IO(OR＾=1.857,95%CI:1.064～3.240),intraoperative fistula(OR＾=1.696,95%CI:1.085～2.651),LRRCC with LH(OR＾=1.084,95%CI:1.012～1.161),LRRCC with RH(OR＾=1.164,95%CI:1.070～1.267),postoperative abdominal infection(OR＾=1.904,95%CI:1.019～3.558)were all independent risk factors for IO in patients with CRC after LRRCC(P<0.05).Conclusion TNM stage Ⅲ,lymph node metastasis,preoperative anemia,preoperative hypoproteinemia,history of abdominal operation,preoperative IO,LRRCC with LC,LRRCC with RH,intraoperative fistula and postoperative abdominal infection are independent risk factors for IO in CRC patients after LRRCC.Clinically,relevant high-risk CRC patients can be treated accordingly to reduce the risk of IO.

The differences in chemical quality characteristics between Xinjiang Rehmannia glutinosa and R. glutinosa were analyzed to provide a theoretical basis for the introduction and quality control of R. glutinosa. In this study, the high performance liquid chromatography(HPLC) fingerprints of 6 batches of Xinjiang R. glutinosa and 10 batches of R. glutinosa samples were established. The content of iridoid glycosides, phenylethanoid glycosides, monosaccharides, oligosaccharides, and polysaccharides in Xinjiang R. glutinosa and R. glutinosa was determined by high performance liquid chromatography-diode array detection(HPLC-DAD), high performance liquid chromatography-evaporative light scattering detection(HPLC-ELSD), and ultraviolet-visible spectroscopy(UV-Vis). The determination results were analyzed with by chemical pattern recognition and entropy weight TOPSIS method. The results showed that there were 19 common peaks in the HPLC fingerprints of the 16 batches of R. glutinosa, and catalpol, aucubin, rehmannioside D, rehmannioside A, hydroxytyrosol, leonuride, salidroside, cistanoside A, and verbascoside were identified. Hierarchical cluster analysis(HCA) and principal component analysis(PCA) showed that Qinyang R. glutinosa, Mengzhou R. glutinosa, and Xinjiang R. glutinosa were grouped into three different categories, and eight common components causing the chemical quality difference between Xinjiang R. glutinosa and R. glutinosa in Mengzhou and Qinyang of Henan province were screened out by orthogonal partial least squares discriminant analysis(OPLS-DA). The results of content determination showed that there were glucose, sucrose, raffinose, stachyose, polysaccharides, and nine glycosides in Xinjiang R. glutinosa and R. glutinosa samples, and the content of catalpol, rehmannioside A, leonuride, cistanoside A, verbascoside, sucrose, and glucose was significantly different between Xinjiang R. glutinosa and R. glutinosa. The analysis with entropy weight TOPSIS method showed that the comprehensive quality of R. glutinosa in Mengzhou and Qinyang of Henan province was better than that of Xinjiang R. glutinosa. In conclusion, the types of main chemical components of R. glutinosa and Xinjiang R. glutinosa were the same, but their content was different. The chemical quality of R. glutinosa was better than Xinjiang R. glutinosa, and other components in R. glutinosa from two producing areas and their effects need further study.

ObjectiveNeuroinflammation plays a crucial role in both the onset and progression of ischemic stroke, exerting a significant impact on the recovery of the central nervous system. Excessive neuroinflammation can lead to secondary neuronal damage, further exacerbating brain injury and impairing functional recovery. As a result, effectively modulating and reducing neuroinflammation in the brain has become a key therapeutic strategy for improving outcomes in ischemic stroke patients. Among various approaches, targeting immune regulation to control inflammation has gained increasing attention. This study aims to investigate the role of in vitro induced regulatory T cells (Treg cells) in suppressing neuroinflammation after ischemic stroke, as well as their potential therapeutic effects. By exploring the mechanisms through which Tregs exert their immunomodulatory functions, this research is expected to provide new insights into stroke treatment strategies. MethodsNaive CD4⁺ T cells were isolated from mouse spleens using a negative selection method to ensure high purity, and then they were induced in vitro to differentiate into Treg cells by adding specific cytokines. The anti-inflammatory effects and therapeutic potential of Treg cells transplantation in a mouse model of ischemic stroke was evaluated. In the middle cerebral artery occlusion (MCAO) model, after Treg cells transplantation, their ability to successfully migrate to the infarcted brain region and their impact on neuroinflammation levels were examined. To further investigate the role of Treg cells in stroke recovery, the changes in cytokine expression and their effects on immune cell interactions was analyzed. Additionally, infarct size and behavioral scores were measured to assess the neuroprotective effects of Treg cells. By integrating multiple indicators, the comprehensive evaluation of potential benefits of Treg cells in the treatment of ischemic stroke was performed. ResultsTreg cells significantly regulated the expression levels of both pro-inflammatory and anti-inflammatory cytokines in vitro and in vivo, effectively balancing the immune response and suppressing excessive inflammation. Additionally, Treg cells inhibited the activation and activity of inflammatory cells, thereby reducing neuroinflammation. In the MCAO mouse model, Treg cells were observed to accumulate in the infarcted brain region, where they significantly reduced the infarct size, demonstrating their neuroprotective effects. Furthermore, Treg cell therapy notably improved behavioral scores, suggesting its role in promoting functional recovery, and increased the survival rate of ischemic stroke mice, highlighting its potential as a promising therapeutic strategy for stroke treatment. ConclusionIn vitro induced Treg cells can effectively suppress neuroinflammation caused by ischemic stroke, demonstrating promising clinical application potential. By regulating the balance between pro-inflammatory and anti-inflammatory cytokines, Treg cells can inhibit immune responses in the nervous system, thereby reducing neuronal damage. Additionally, they can modulate the immune microenvironment, suppress the activation of inflammatory cells, and promote tissue repair. The therapeutic effects of Treg cells also include enhancing post-stroke recovery, improving behavioral outcomes, and increasing the survival rate of ischemic stroke mice. With their ability to suppress neuroinflammation, Treg cell therapy provides a novel and effective strategy for the treatment of ischemic stroke, offering broad application prospects in clinical immunotherapy and regenerative medicine.
