OBJECTIVES: To investigate the chain mediating role of family care and emotional management in the relationship between social support and anxiety among rural primary school students. METHODS: A questionnaire survey was conducted among students in grades 4 to 6 from four counties in Hunan Province. Data were collected using the Social Support Rating Scale, Family Care Index Scale, Emotional Intelligence Scale, and Generalized Anxiety Disorder -7. Logistic regression analysis was used to explore the influencing factors of anxiety symptoms. Mediation analysis was conducted to assess the chain mediating effects of family care and emotional management between social support and anxiety. RESULTS: A total of 4 141 questionnaires were distributed, with 3 874 valid responses (effective response rate: 93.55%). The prevalence rate of anxiety symptoms among these students was 9.32% (95%CI: 8.40%-10.23%). Significant differences were observed in the prevalence rates of anxiety symptoms among groups with different levels of social support, family functioning, and emotional management ability (P<0.05). The total indirect effect of social support on anxiety symptoms via family care and emotional management was significant (β=-0.137, 95%CI: -0.167 to -0.109), and the direct effect of social support on anxiety symptoms remained significant (P<0.05). Family care and emotional management served as significant chain mediators in the relationship between social support and anxiety symptoms (β=-0.025,95%CI:-0.032 to -0.018), accounting for 14.5% of the total effect. CONCLUSIONS Social support can directly affect anxiety symptoms among rural primary school students and can also indirectly influence anxiety symptoms through the chain mediating effects of family care and emotional management. These findings provide scientific evidence for the prevention of anxiety in primary school students from multiple perspectives.

【Objective】 To explore the effects of finasteride on the gene expression in patients with benign prostatic hyperplasia (BPH) through transcriptome analysis. 【Methods】 Postoperative prostate tissues from patients who underwent prostatectomy at Peking University Third Hospital during Oct.2020 and Oct.2021 were collected.The patients were divided into medication group and non-medication group based on whether they had taken finasteride for a long time before surgery, with 8 patients in either groups.Transcriptome sequencing analysis was performed and the results were validated with qPCR and immunohistochemistry analysis. 【Results】 Compared with the non-medication group, 857 up-regulated and 806 down-regulated genes were screened in the medication group.Pathway enrichment analysis showed that finasteride induced down-regulation of vascular endothelial growth factor D (VEGFD) expression in the focal adhesion pathway.Inter group network analysis suggested that the calcium signaling pathway was key in the entire process.GSEA enrichment analysis further revealed the up regulation of CD38 gene expression in the calcium signaling pathway.The qPCR and immunohistochemistry analysis supported the transcriptome results mentioned above, and found that androgen receptor (AR) expression was also increased. 【Conclusion】 Finasteride reduces prostate microvascular formation by downregulating the expression of VEGFD in the focal adhesion pathway, thereby reducing the risk of bleeding during prostate hyperplasia surgery. Long-term use of finasteride leads to the up regulation of CD38 expression in the calcium signaling pathway, which may lead to the development of finasteride resistance.

Transcatheter aortic valve replacement(TAVR)has emerged as a promising therapeutic alternative for addressing aortic valve-related pathologies.However,the occurrence of rapid arrhythmias linked to TAVR procedures is progressively drawing scrutiny.Presently,pharmacologic interventions constitute the mainstay of managing atrial arrhythmias related to TAVR,while the potential of ablation as a viable treatment modality remains undefined.Notably,in cases where the arrhythmia's genesis is presumed to be intricately linked to the prosthetic valve,the practicality and safety of ablation procedures remain unverified.Our institution has successfully ventured into radiofrequency ablation for a distinctive patient presenting with this intricate condition,thereby tentatively affirming the efficacy and safety of catheter ablation administered on the surface of prosthetic valves.

Objective:To investigate the expression and clinical significance of CD30 in patients with diffuse large B-cell lymphoma(DLBCL).Methods:A retrospective analysis was conducted on 124 cases of primary DLBCL diagnosed at Changzhou Second People's Hospital Affiliated with Nanjing Medical University from January 2018 to July 2020.The expression of CD30 in patients with DLBCL was detected by immunohistochemical method,and the clinicopathological characteristics were analyzed and compared between CD30+and CD30-groups.Kaplan-Meier analysis was used for survival analysis.The relationship between CD30 expression and clinical features and prognosis were analyzed.Results:Among the 124 patients with DLBCL,19 patients expressed CD30,and the positive rate is 15.32％.The clinico-pathological characteristics of CD30+in patients with DLBCL were characterized by low age,more common in males,fewer extranodal lesions,lower international prognostic index(IPI),GCB type being more common in Hans subtype,and achieving better therapeutic effects(P＜0.05).However,there were no significant statistical differences in B-symptoms(P=0.323),Ann Arbor staging(P=0.197),Eastern Cooperative Oncology Group(ECOG)score(P=0.479),lactate dehydrogenase(LDH)(P=0.477),and the involvement of bone marrow(P=0.222).There were significant differences in OS and PFS between the CD30+and CD30-groups(x2=5.653,P=0.017;x2=4.109,P=0.043),the CD30+group had a better prognosis than that of the CD30-group.The results of subgroup analysis showed that the CD30+group in the IPI score=1-2,LDH elevated group had a better prognosis(P＜0.05).In the subgroups of Ann Arbor staging Ⅲ-Ⅳ(P=0.055)and non GCB type(P=0.053),the CD30+group had a good prognosis trend,but the difference was not statistically significant.The results of univariate analysis showed that the good prognosis of DLBCL patients was closely related to CD30+expression,no B-symptoms,early Ann Arbor staging,low ECOG score,normal LDH,low IPI score,fewer extranodal involvement,and obtaining the best therapeutic effect as CR(all P＜0.05).COX multivariate regression analysis showed that the presence of B-symptoms and achieving the best therapeutic effect as Non-CR were independent risk factors affecting the prognosis of DLBCL patients(P＜0.05).Conclusion:The CD30+expression in DLBCL patients indicates a good prognosis and has certain diagnostic value in evaluating the prognosis of DLBCL patients.

OBJECTIVE: To observe clinical efficacy of percutaneous endoscopic transforaminal discectomy (PETD) and target radioffrequency thermal coblation nucleoplasty(CN) on inclusive lumbar disc herniation(LDH) in different age groups, and provide a basis for clinical formulation of precise and individualized treatments. METHODS: A retrospective analysis of 219 patients with lumbar disc herniation treated with PETD and CN between January 2018 and June 2021 was performed, in which 107 patients were treated with PETD and 112 with CN. Patients were stratified by age into young group(≤45 years old), middle-aged group(>45 years old and <60 years old) and older group(≥60 years old). Before treatment, 3 days, 1 month and 6 months after treatment, visual analogue scale (VAS), Japanese Orthopaedic Association (JOA) score, infrared thermal imaging temperature difference (△T) and lumbar range of motion (ROM) were evaluated and clinical efficacy were compared in the different age groups between two treatment methods. RESULTS: ①VAS and JOA score outcomes, in the same age group and the same treatment method, the VAS and JOA scores at different time points postoperatively were obviously improved (P<0.05). For the same age group and the different treatment methods, the older group had lower VAS and higher JOA scores after PETD than after CN (P<0.05), and there was no significant difference between the young group and middle-aged group (P>0.05). There was no significant difference in VAS and JOA scores at the same time between age groups by PETD treatment (P>0.05). The VAS was higher and the JOA score was lower in older group than in young group and middle-aged group at 1, 6 months after CN treatment(P<0.05). ②△T and ROM outcomes, in the same age group and same treatment method, postoperative △T and ROM at different time points were obviously improved(P<0.05). There was no significant difference in △T between two methods of PETD and CN at the same age(P>0.05), there was no significant difference in ROM between young group and middle-aged group(P>0.05), ROM was higher after PETD treatment than after CN treatment(P<0.05). There was no significant difference in △T and ROM at the same time between age groups by PETD treatment(P>0.05). There was no significant difference in △T between age groups by CN treatment, but the ROM was smaller in older group than in young group and middle-aged group after CN treatment(P<0.05). CONCLUSION Both PETD and CN for inclusive LDH have good efficacy, the curative benefit for older patients receiving PETD within 6 months after surgery more than CN, and CN is more appropriate for young and middle-aged patients.

ObjectiveTo investigate the effect of LncRNA GAPLINC on the cell proliferation of RA-FLSs. MethodsRA-FLSs were cultured from synovial specimens. The expression of LncRNA GAPLINC in RA-FLSs and trauma-FLSs groups was detected by qRCR. GAPLINC suppression was transfected by siRNA and the inhibition efficiency was detected by qRCR. Flow cytometry was adopted to determine the change of cell growth and cell cycle distribution. 【ResμLts】 The expression of LncRNA GAPLINC was significantly higher in RA-FLSs than that of the trauma-FLSs （P<0.05）.Transfection of GAPLINC-siRNA significantly decreased the expression of LncRNA GAPLINC. GAPLINC silence in RA-FLSs revealed significant inhibition in cell proliferation which was showed by the reduced cell number in S phase（P<0.05）. Moreover， flow cytometry assay showed GAPIINC-siRNA treatment group had an accumμLation of cells in the G0/G1 phase and decreased RA-FLSs in the S and G2/M phase（P<0.05）. After GAPLINC knockdown， mRNA and protein levels of Cyclin D1 and PCNA， which were positively correlated with proliferative phenotype， were decreased （P<0.05）， while p21， which was negatively correlated with proliferative phenotype， was up-regμLated （P<0.05）. ConclusionsThe mRNA expression of GAPLINC was higher in RA-FLSs compared with trauma-FLSs ，which was statistically significant（P<0.05）. The silence of LncRNA GAPLINC coμLd significantly inhibit RA-FLSs cell growth and suppress the cell cycle transformation， which suggests that GAPLINC may play a role in the regμLation of proliferation of RA-FLSs， leading to synovial hyperplasia and contributing to RA progression.

Based on the concept of quality by design(QbD), the Box-Behnken design-response surface methodology combined with standard relation(SR) and analytic hierarchy process(AHP)-entropy weight method(EWM) was applied to optimize the extraction process of the classic prescription Yihuang Decoction. The content of geniposidic acid, phellodendrine hydrochloride, and berberine hydrochloride in Yihuang Decoction, the extract yield, and fingerprint similarity were used as the critical quality attributes(CQAs) of the extraction process. The extraction time, water addition, and extraction times were used as the critical process parameters(CPPs). After determining the levels of each factor and level through single-factor experiments, response surface experiments were designed according to the Box-Behnken principle, and the experimental results were analyzed. The SR between each sample and the reference sample under various evaluation indicators of different extraction parameters was calculated. The weights of the five evaluation indicators were determined using AHP-EWM, followed by comprehensive evaluation. A function model between CPPs and CQAs characterized by comprehensive scores was established to predict the optimal extraction process parameters. In the final comprehensive weight coefficients, the yield rate accounted for 43.1%, and the content of berberine hydrochloride, phellodendrine hydrochloride, and geniposidic acid accounted for 35.1%, 6.3%, and 15.5%, respectively. After comprehensive score analysis with SR, the established second-order polynomial model was statistically significant(P<0.01, and the lack of fit was not significant). The predicted optimal extraction conditions for Yihuang Decoction were determined as follows: 8-fold volume of water, extraction time of 1.5 h, and extraction once. The mean comprehensive score of the validation experiment was 85.77, with an RSD of 0.99%, and it met the quality control stan-dards for the reference sample of Yihuang Decoction. The results indicate that the optimized extraction process for Yihuang Decoction is stable and reliable, and the water extract is close in quality attributes to the reference sample. This can serve as a foundation for the research and development of granules in the future. Box-Behnken design-response surface methodology combined with SR and AHP-EWM can provide references for the modern extraction process research of other classic prescriptions.
