Objective:To investigate the changes of T lymphocyte subsets in patients with stage Ⅰ and Ⅱ cervical cancer after surgery and their relationship with postoperative lymph node metastasis according to the International Federation of Gynecology and Obstetrics (FIGO) stage (2014) .Methods:A total of 192 patients with FIGO stage ⅠA, ⅠB1, ⅠB2 and ⅡA1 who received radical cervical cancer resection and pelvic lymph node dissection in People's Hospital of Yuechi County of Sichuan Province and West China Guang'an Hospital of Sichuan University from November 2018 to November 2020 were selected for this study. According to FIGO stage, patients were divided into stage Ⅰ group ( n=85) and stage Ⅱ group ( n=107) . The dynamic changes of T lymphocytes subsets in patients with different FIGO stages were compared before and after surgery. Repeated measurement of variance was used to analyze the levels of T lymphocytes subsets in patients of different stages during treatment. Logistic regression was used to analyze the influencing factors of postoperative lymph node metastasis in patients with cervical cancer. Multivariate logistic regression was used to analyze the relationship between T lymphocytes subsets and postoperative lymph node metastasis. Receiver operator characteristic (ROC) curve was used to analyze the predictive efficacy of T lymphocytes level in postoperative lymph node metastasis. Results:The postoperative lymph node metastasis rate in stage Ⅱ patients [32.71% (35/107) ] was higher than that in stage Ⅰ patients [14.12% (12/85) ], with a statistically significant difference ( χ2=8.86, P=0.003) . Compared with the stage Ⅱ group, the levels of CD3 +, CD4 + T lymphocytes and CD4 +/CD8 + ratio were significantly higher in the stage Ⅰ group 1 day before surgery (all P<0.001) , and the level of CD8 + T lymphocytes was significantly lower ( P<0.001) . The levels of CD3 +, CD4 +, CD8 + T lymphocytes and the ratio of CD4 +/CD8 + showed dynamic changes at different stages after surgery. On 1, 7 and 30 days after surgery, the levels of CD3 +, CD4 + T lymphocytes and the ratio of CD4 +/CD8 + in stage Ⅰ group were higher than those in stage Ⅱ group (all P<0.001) , CD8 + T cell levels were lower than those in stage Ⅱ group (all P<0.001) . There were statistically significant differences in T lymphocytes subsets CD3 +, CD4 +, CD8 + and CD4 +/CD8 + time effect, intergroup effect and interaction effect between the two groups (all P<0.001) . Univariate analysis showed that the pathological type ( OR=1.85, 95% CI: 1.14-2.33, P=0.015) , differentiation degree ( OR=1.93, 95% CI: 1.18-2.67, P=0.024) , depth of myometrial invasion ( OR=2.08, 95% CI: 1.26-2.59, P=0.012) , tumor morphology ( OR=2.17, 95% CI: 1.57-2.63, P=0.009) , parametrial invasion ( OR=1.95, 95% CI: 1.43-2.76, P=0.036) and lymphovascular space invasion ( OR=2.03, 95% CI: 1.28-2.57, P=0.021) were the influencing factors for postoperative lymph node metastasis in patients with FIGO stage Ⅰ and Ⅱ cervical cancer. Multivariate analysis showed that the degree of differentiation ( OR=1.75, 95% CI: 1.08-2.03, P=0.015) , depth of myometrial invasion ( OR=2.30, 95% CI: 1.43-2.84, P=0.021) , parametrial invasion ( OR=2.50, 95% CI: 1.76-2.97, P=0.018) and lymphovascular space invasion ( OR=1.96, 95% CI: 1.03-2.51, P=0.033) were independent factors for postoperative lymph node metastasis in patients with FIGO stage Ⅰ and Ⅱ cervical cancer. Multivariate logistic regression analysis showed that the levels of CD3 +, CD4 +, CD8 + T cells and the ratio of CD4 +/CD8 + in patients with stage Ⅰ and stage Ⅱ cervical cancer 1 day before surgery were independent influencing factors for postoperative lymph node metastasis (all P<0.05) . ROC curve analysis showed that the areas under the curve of CD3 +, CD4 +, CD8 + T lymphocytes levels and the ratio of CD4 +/CD8 + in stage Ⅰ patients 1 day before surgery for predicting postoperative lymph node metastasis were 0.86, 0.82, 0.83, 0.89, respectively, and those in stage Ⅱ patients were 0.90, 0.93, 0.87, 0.95, respectively. CD4 +/CD8 + ratio was significantly more effective in predicting postoperative lymph node metastasis than other indexes (all P<0.001) . Conclusions:The levels of CD3 +, CD4 + T lymphocytes, and the CD4 +/CD8 + ratio in patients with FIGO stage Ⅰ and Ⅱ cervical cancer are significantly higher in 1-30 days after surgery than before, while the level of CD8 + T lymphocytes is significantly lower than before. There is a significant correlation between T lymphocytes subsets and lymph node metastasis after surgery. In addition, low differentiation, depth of myometrial invasion ≥1/2, parametrial invasion, and lymphovascular space invasion are independent risk factors for postoperative lymph node metastasis.

Objective: To explore the relative importance of different food attributes and levels in food decision making of school aged children, and to understand their meal preferences, so as to provide the evidence for formulating precise intervention strategies for dietary behaviours of school aged children. Methods: From May to June 2024, a total of 854 children aged 11 to 15 years old were selected from 2 middle schools (each school in urban and rural areas) in both Hubei Province and Anhui Province by stratified cluster random sampling method to conduct a D-optimal discrete choice experiment. The mixed Logit model was used to analyze children s preference for meal attributes and different levels, and to calculate the relative importance (RI) of attributes and willingness to pay (WTP) in meal choices. Results: The included five food attributes had statistical significance on meal choice of school aged children ( P <0.05). The relative importance of food attributes affecting the meal choices of school aged children in descending order were dining mode ( RI =31.26%), food varieties ( RI =30.56%), cooking method( RI =23.84%), taste( RI =8.06%) and price ( RI =6.27%). Among them, school aged children preferred home cooked meals ( β =0.74) (WTP=86.3 yuan),varied foods(grain/tubers+vegetables+fish, meat, eggs and beans) ( β =0.61) (WTP=71.9 yuan), fried/roasted cooking ( β =0.51) and spicy taste ( β =0.33).Price was negatively correlated with meal choices( β =-0.01) ( P <0.05). Based on residential area and body mass index (BMI), the stratified analysis showed that dining mode was highest in the relative importance for rural children with overweight and obese children ( RI =31.28%,34.17%), both of whom preferred home cooked meals ( β =0.76, 0.91), and meals containing fish, meat, eggs and beans with grain/tubers or grain/tubers and vegetables in terms of food choice (area: β =0.53, 0.53 ; BMI: β =0.55, 0.56) ( P <0.05). Conclusions School aged children have different preferences for different attributes of meals. The quality of school meals should be improved,the cost of buying healthy meals should be reduced,targeted family health education should be carried out,and healthy cooking methods should be advocated.

OBJECTIVE To systematically evaluate medication risk prediction models for hospitalized adult patients and provide references for their development and clinical application. METHODS Databases including PubMed， Embase， Web of Science， CNKI， Wanfang data， VIP and CBM were searched for studies on medication risk prediction models from their inception to May 2024. After screening the literature， extracting data， and evaluating the quality of the literature， descriptive analysis was performed on the results of the included studies. RESULTS A total of 13 studies were included， involving 12 models. Nine studies used Logistic regression algorithm for modeling， and the number of included predictive factors ranged from 3 to 11； the area under the receiver operating characteristic curve ranged from 0.65 to 0.865. The literature quality evaluation results showed that 10 studies had high risk of bias； 10 studies had high applicability risk. A total of 31 predictive factors were extracted， including 15 items of basic patient information， 3 test indicators， and 5 items of medication information， and 8 others. CONCLUSIONS The existing medication risk prediction models for hospitalized adult inpatients are mainly Logistic regression algorithm， with predictive factors mainly focusing on basic indicators such as demographics. The overall prediction performance of the models needs to be improved， and the overall risk of bias is relatively high.

This study investigates the pharmacokinetics and metabolic characteristics of three marine-derived piericidins as potential drug leads for kidney disease: piericidin A (PA) and its two glycosides (GPAs), glucopiericidin A (GPA) and 13-hydroxyglucopiericidin A (13-OH-GPA). The research aims to facilitate lead selection and optimization for developing a viable preclinical candidate. Rapid absorption of PA and GPAs in mice was observed, characterized by short half-lives and low bioavailability. Glycosides and hydroxyl groups significantly enhanced the absorption rate (13-OH-GPA > GPA > PA). PA and GPAs exhibited metabolic instability in liver microsomes due to Cytochrome P450 enzymes (CYPs) and uridine diphosphoglucuronosyl transferases (UGTs). Glucuronidation emerged as the primary metabolic pathway, with UGT1A7, UGT1A8, UGT1A9, and UGT1A10 demonstrating high elimination rates (30%-70%) for PA and GPAs. This rapid glucuronidation may contribute to the low bioavailability of GPAs. Despite its low bioavailability (2.69%), 13-OH-GPA showed higher kidney distribution (19.8%) compared to PA (10.0%) and GPA (7.3%), suggesting enhanced biological efficacy in kidney diseases. Modifying the C-13 hydroxyl group appears to be a promising approach to improve bioavailability. In conclusion, this study provides valuable metabolic insights for the development and optimization of marine-derived piericidins as potential drug leads for kidney disease.

Long-term hypertension causes excessive vascular remodeling and leads to adverse cardiovascular events. Balance of ubiquitination and deubiquitination has been linked to several chronic conditions, including pathological vascular remodeling. In this study, we discovered that the expression of ubiquitin-specific protease 25 (USP25) is significantly up-regulated in angiotensin II (Ang II)-challenged mouse aorta. Knockout of Usp25 augments Ang II-induced vascular injury such as fibrosis and endothelial to mesenchymal transition (EndMT). Mechanistically, we found that USP25 interacts directly with Forkhead box O3 (FOXO3) and removes the K63-linked ubiquitin chain on the K258 site of FOXO3. We also showed that this USP25-mediated deubiquitination of FOXO3 increases its binding to light chain 3 beta isoform and autophagosomic-lysosomal degradation of FOXO3. In addition, we further validated the biological function of USP25 by overexpressing USP25 in the mouse aorta with AAV9 vectors. Our studies identified FOXO3 as a new substrate of USP25 and showed that USP25 may be a potential therapeutic target for excessive vascular remodeling-associated diseases.

BACKGROUND: The optimal antidepressant dosages remain controversial. This study aimed to analyze the efficacy of antidepressants and characterize their dose-response relationships in the treatments of major depressive disorders (MDD). METHODS: We searched multiple databases, including the Embase, Cochrane Central Register of Controlled Trials, PubMed, and Web of Science, for the studies that were conducted between January 8, 2016, and April 30, 2023. The studies are double-blinded, randomized controlled trials (RCTs) involving the adults (≥18 years) with MDD. The primary outcomes were efficacy of antidepressant and the dose-response relationships. A frequentist network meta-analysis was conducted, treating participants with various dosages of the same antidepressant as a single therapy. We also implemented the model-based meta-analysis (MBMA) using a Bayesian method to explore the dose-response relationships. RESULTS: The network meta-analysis comprised 135,180 participants from 602 studies. All the antidepressants were more effective than the placebo; toludesvenlafaxine had the highest odds ratio (OR) of 4.52 (95% confidence interval [CI]: 2.65-7.72), and reboxetine had the lowest OR of 1.34 (95%CI: 1.14-1.57). Moreover, amitriptyline, clomipramine, and reboxetine showed a linear increase in effect size from low to high doses. The effect size of toludesvenlafaxine increased significantly up to 80 mg/day and subsequently maintained the maximal dose up to 160 mg/day while the predictive curves of nefazodone were fairly flat in different dosages. CONCLUSIONS: Although most antidepressants were more efficacious than placebo in treating MDD, no consistent dose-response relationship between any antidepressants was observed. For most antidepressants, the maximum efficacy was achieved at lower or middle prescribed doses, rather than at the upper limit.

Ileocecal duplication is a rare congenital gastrointestinal abnormality,with lesions predominantly localized near the ileocecal valve and manifesting as cystic structures.Clinically,it presents with diverse symptoms,including abdominal pain,vomiting,abdominal mass,etc.However,symptoms such as intussusception and appendicitis are easily confused with it.Furthermore,the imaging features of ileocecal duplication are nonspecific,which further increases the risk of misdiagnosis.Treatment options include laparoscopic surgery and laparotomy.Notably,laparoscopic surgery is highly feasible,especially for infants and young children,and achieves a prognosis comparable to that of laparotomy.In the case report presented in this study,a 1-year-old male patient was admitted to the hospital due to abdominal pain.Definitive diagnosis could not be established through comprehensive imaging examinations,and the diagnosis of ileocecal duplication cyst was ultimately confirmed surgically.Additionally,the diagnosis,imaging features,treatment,and prognosis of ileocecal duplication are systematically collated and summarized.

Objective:To investigate the protective effect of PSD95 on neurobehavioral abnormalities and synaptic damage in cortex induced by hypoxia exposure in mice.Methods:The 3-week-old C57BL/6 male mice were injected with neuron-specific adeno-associated virus through stereotaxic brain after 7 days of normal environment adaptation.The mice were divided into normoxia group(AAV-NC-Nor),control hypoxia group(AAV-NC-Hyp),normal oxygen group with over-expression of postsynaptic density-95(PSD95)(AAV-PSD95-Nor),and hypoxia group with over-expression of PSD95(AAV-PSD95-Hyp).Using a hypobaric hypoxia chamber,PSD95-overexpressing mice were continuously ex-posed to hypoxic conditions for 14 days to establish a hypoxia exposure model.The open field,elevated cross maze and conditioned fear tests were used to detect the neurobehavioral activities of mice,and Golgi staining was used to observe the density of neuronal dendritic spines in cortex.The expression of PSD95,SYN1 and N-methyl-D-aspartate receptor subtype 2A(NMDAR2A)were detected by Western blot.Result:Compared with the normal oxygen group,the total distance and average speed of exercise in the open field experiment of mice in hypoxia group increased(P＜0.01),the rigidity time of mice in the conditioned fear box decreased(P＜0.01),and the density of dendritic spines in cortical region decreased(P＜0.05).The expressions of PSD95,SYN1 and NMDAR2A were decreased(P＜0.05).After the over-expression of PSD95,the autonomic activity of mice was reduced,the fear memory was relieved(P＜0.05),the dendrite density was reversed(P＜0.05),and the expression of synaptic related protein was increased(P＜0.05).Conclusion:Over-expression of PSD95 can alleviate neurobehavioral abnormalities and decline of fear memory induced under hypoxia exposure,protect neuronal dendritic spine injury in cortical region,and up-regulate the expression of syn-aptic protein.
