Objective:Using surface-based morphometry (SBM), this study longitudinally tracks dynamic changes in whole-brain cortical morphological parameters in depression patients before and after vortioxetine treatment. Through three-dimensional topological characterization, we investigate the neuroanatomical correlations between cortical structural reorganization and improvements in affective symptoms and cognitive functions.Methods:Prospectively collected clinical data from 22 outpatients with depression (10 males and 12 females, aged 18-50 years, mean age 28.1±9.1) who attended Beijing Huilongguan Hospital clinic from October 2018 to December 2019. An age-matched healthy control group ( n=21; 10 males and 11 females, aged 22-44 years, mean age 30.8±6.6) was recruited concurrently. The Hamilton Rating Scale for Anxiety (HAMA), the 17-item Hamilton Depression Scale (HAMD 17), and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) were used to evaluate the severity of depressive symptoms and cognitive function in patients. Structural magnetic resonance imaging (sMRI) was performed to assess brain structural indices in depression patients before and after vortioxetine treatment, as well as in healthy controls. Whole-brain cortical structure measurements were calculated for all subjects using CAT12 software. Paired-sample t-tests were used to compare changes in cortical structure and clinical scale scores in depression patients before and after treatment, and two-sample t-tests were conducted to compare whole-brain cortical structure differences between patients (pre-and post-treatment) and healthy controls. Multiple regression analysis in SPM 12 was applied to examine the correlation between post-treatment cortical structural indices and clinical and cognitive scale scores in patients. Spearman correlation analysis was used to evaluate the correlation between changes in whole-brain cortical structure and cognitive function before and after vortioxetine treatment. Results:After vortioxetine treatment, patients with depression exhibited significant reductions in HAMA and HAMD 17 scores, along with significant increases in immediate memory, delayed memory, and total RBANS scores, with statistically significant differences observed ( t=8.43, 12.28, -4.71, -2.41, -3.86 respectively; all P<0.05), while there were no significant changes in visual span, language function, or attention ( P>0.05). Compared to healthy controls, depression patients showed a significantly reduced gyrification index in the right insula/superior temporal gyrus before treatment (28.74±1.20 vs 27.44±1.17; t=4.47, P<0.001), but no significant differences in whole-brain cortical structure were observed before and after treatment or between post-treatment patients and healthy controls ( P>0.05). Correlation analysis indicated that fractal dimension was negatively correlated with HAMA and HAMD 17 scores after treatment, while gyrification index was positively correlated with HAMD 17 ( rpartial=-0.79, -0.83, 0.72; P<0.05). Visual span was positively correlated with fractal dimension ( rpartial=0.78) and negatively correlated with gyrification index ( rpartial=-0.73, P<0.05). Sulcal depth was negatively correlated with attention and RBANS total scores ( rpartial=-0.77, -0.75; P<0.05). Additionally, changes in gyrification index in the left fusiform gyrus were positively correlated with changes in attention ( r=0.51), changes in gyrification index in the left posterior cingulate gyrus were positively correlated with changes in immediate memory ( r=0.58), and changes in sulcal depth in the left superior frontal gyrus were negatively correlated with changes in language ability ( r=-0.79) (both P<0.05). Conclusion:Vortioxetine treatment can improve anxiety and depressive symptoms in depression patients, as well as enhance certain cognitive functions, while also affecting cortical structure in the specific cortical area. Changes in cortical structure after vortioxetine treatment are closely related to clinical symptom improvement and cognitive function changes.

The integrated medical and elderly care is a major livelihood issue in China, and also an important measure to positively respond to the national strategy of population aging.In July 2024, the Aging Health Department of the National Health Commission issued the "Standard for the Elderly to Shift of Beds Between Elderly Care and Medical Zones Within the Integrated Area of Medical Treatment and Maintenance(WS/T845-2024)" . This standard takes comprehensive geriatric assessment as the main focus, determines the dynamic evaluation indicators for bed conversion between elderly care and medical zones, and establishes an evaluation standard, which is of great significance for standardizing the development of the integrated area of medical treatment and maintenance and meeting the health needs of the elderly in different periods.This article introduced the background and significance of the standard formulation, interpreted the content of the standard in detail, and summarized the overall thinking and usage methods when formulating the standard, which was helpful for relevant personnel to correctly understand the standard and promote its implementation.

Objective To investigate the expression of serum exosomal long non-coding RNA X chromo-some inactivation specific transcript(LncRNA XIST)and microRNA(miR)-130a-3p in gestational diabetes mellitus(GDM)patients and its relationship with pregnancy outcome.Methods A total of 149 GDM patients(GDM group)and 149 healthy pregnant women(control group)admitted to the hospital from January 2021 to January 2024 were selected.Serum exosomal LncRNA XIST,miR-130a-3p and glucose and lipid metabolism indexes of the two groups were detected and compared.The correlation of LncRNA XIST and miR-130a-3p levels with glycolipid metabolism indexes was analyzed by Pearson method.Univariate and multivariate Logis-tic regression models were used to analyze the influencing factors of pregnancy outcomes in GDM patients.Re-ceiver operating characteristic(ROC)curve was used to analyze the predictive efficacy of serum exosomal Ln-cRNA XIST and miR-130a-3p levels alone and in combination for pregnancy outcomes in GDM patients.Results Serum exosomal LncRNA XIST levels,fasting insulin(FINS),fasting blood glucose(FBG),insulin resistance index(HOMA-IR),2-hour postprandial glucose(2 hPG),total cholesterol(TC),triglyceride(TG)and low density lipoprotein cholesterol(LDL-C)levels in GDM group were higher than those in control group(P＜0.05),and the levels of miR-130a-3p and high density lipoprotein cholesterol(HDL-C)were lower than those in the control group(P＜0.05).LncRNA XIST was positively correlated with FINS,FBG,HOMA-IR,2 hPG,TC,TG and LDL-C,and negatively correlated with HDL-C(P＜0.05).miR-130a-3p was negatively correlated with FINS,FBG,HOMA-IR,2 hPG,TC,TG and LDL-C,and positively correlated with HDL-C(P＜0.05).Among the 149 GDM patients,43 cases showed adverse pregnancy outcome,accounting for 28.86％.The increase level of FBG,the increase level of LncRNA XIST and the increase of HOMA-IR were risk factors for adverse pregnancy outcome in GDM patients,while the increase of miR-130a-3p was a protec-tive factor.The ROC curve analysis showed that the predictive efficacy of combined detection was superior to that of single indicator detection.Conclusion The serum exosomal LncRNA XIST of GDM patients is highly expressed,and miR-130a-3p is lowly expressed,and the combined detection of the above indexes has a high predictive value for pregnancy outcome.

Radiotherapy is an important part of the standard treatment regimen for rectal cancer, bringing survival benefits and improved quality of life to patients with rectal cancer. However, the radiotherapy resistance of rectal cancer patients greatly limits the effectiveness of treatment and affects the prognosis of patients. The emergence of nanoparticles provides a new way to improve radiotherapy resistance of rectal cancer, which can overcome radiotherapy resistance by inhibiting DNA damage repair, affecting cell cycle, targeting delivery, enhancing DNA damage, and regulating tumor microenvironment, etc. In this article, complex coordination mechanism leading to radiotherapy resistance in rectal cancer was reviewed, current relevant studies on nanoparticles in improving radiotherapy response in rectal cancer were summarized, and the feasibility and future research direction of the combination of nanoparticles and radiotherapy in clinical treatment of rectal cancer were discussed.

Objective:To investigate the use of folded flap for repair of laryngeal and hypopharyngeal defect and the clinical efficacies of laryngeal and hypopharyngeal function reconstructions after surgery of piriform sinus cancer.Methods:A retrospective analysis was performed for 10 cases of piriform sinus cancer that were treated in the Second Norman Bethune Hospital of Jilin University from January 2020 to April 2023 and all patients were males, aged 42-68 years. The first choice of treatment for all patients was surgery. After function neck dissection and tracheotomy, partial laryngectomy and hypopharyngectomy were carried out. The folded island flaps were prepared and used for the repairs of laryngeal and hypopharyngeal defects and the reconstructions laryngeal and hypopharyngeal functions. The patients were followed up.Results:The laryngeal and pharyngeal cavities were reconstructed well in 10 patients, and all the flaps survived, with no case of pharyngeal fistula. All patients were able to eat normally through the mouth at 2 weeks after surgery without obvious choking, and 4 patients completed the swallowing function evaluation without aspiration or only a small amount of aspiration. All the 10 patients underwent postoperative radiotherapy. The postoperative follow-up time was 5.4-41.4 months, and there was no case with tumor recurrence or death. Laryngoscopy showed that 8 patients had a spacious new laryngeal orifice, which met the conditions for extubation, of whom 7 patients had their tracheal tubes removed and 1 patient was still under observation, and that 2 patients had a slightly narrowed new laryngeal orifice due to a thick skin flap, with further follow-up observation. All patients retained their phonatory functions after surgery.Conclusion:Folded island flap can be used for the function reconstructions of the larynx and hypopharynx after surgery of pyriform sinus cancer.

Neoadjuvant chemoradiotherapy (NCRT) is the standard therapeutic strategy for locally advanced rectal cancer (LARC). Due to the different responses of patients to NCRT, the clinical prognosis of patients varies greatly. Therefore, it is important to establish sensitive biomarkers to predict the response of patients to treatments before NCRT. Immune cells in the tumor microenvironment (TME) were closely related to the efficacy of NCRT in patients with LARC. This paper reviewed the research progress on the relationships of cytotoxic T cells, programmed death-ligand 1 (PD-L1), tumor-associated macrophages (TAMs), regulatory T cells (Treg) and neutrophil to lymphocyte ratio (NLR) with chemoradiotherapy sensitivity in rectal cancer, illustrated the potential and limitations of these immune cells in predicting chemoradiotherapy response in rectal cancer, and provided a feasible direction for future researches.

Objective:To explore the association between cognitive function and the level of gamma-amino-butyric acid(GABA)in anterior cingulate cortex(ACC)before and after treatment in patients with major depres-sion disorder.Methods:Totally 31 medication-naive patients with major depression disorder meeting the criteria of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)and 33 normal controls were col-lected.Each eligible patient received treatment with selective serotonin reuptake inhibitor agents for 8 weeks.The MATRICS Consensus Cognitive Battery(MCCB)was used to evaluate the cognitive function.By means of 1H magnetic resonance spectroscopy,anterior cingulate cortex GABA concentrations were measured.Results:At base-line,the concentration of ACC GABA relative to water(GABA+/W)was lower in the patient group than in the control group(P＜0.05)and increased after treatment(P＜0.05).ACC GABA+/W was negatively associated with verbal learning and visual memory score in patient group at baseline(correlation coefficient and P value were r=-0.40,P＜0.05;r=-0.42,P＜0.05,respectively).The ACC GABA+/W difference resulted of treatment in patient group was positively associated with the difference of working memory score and the difference of reasoning and problem-solving score(correlation coefficient and P value were r=0.58,P＜0.05;r=0.66,P＜0.05,respec-tively).Conclusion:The cognitive dysfunction of patients with major depression disorder may not be related to the degree of depression and anxiety.And improvement of cognitive function may be associated with increase of ACC GABA concentrations.
