BackgroundPatients with depressive episode and schizophrenia have a high risk of suicide. The sleep electroencephalogram power spectral density characteristics of patients with depressive episode accompanied by suicidal behavior and those with schizophrenia may be different， but there is currently a lack of direct comparative studies on these two groups of patients. ObjectiveTo compare the sleep electroencephalogram power spectral density between depressive episode and schizophrenic patients with suicidal behavior， in order to provide references for exploring predictive indicators of suicidal behavior. MethodsFrom June 2018 to December 2020， 20 patients with depressive episode and 20 patients with schizophrenia who had committed suicide within the past month and were treated at the outpatient department of Shenzhen Kangning Hospital were selected. All of them met the diagnostic criteria for depressive episode or schizophrenia as defined in the International Classification of Diseases， tenth edition （ICD-10）. Using a random sampling method， 20 volunteers with matching gender and age to the patient groups were selected from the Cuiping community in Shenzhen as the control group. The subjective sleep of the patients was evaluated using the Insomnia Severity Index （ISI）， the Dysfunctional Belief and Attitude about Sleep （DBAS）， the Disturbing Dreams and Nightmare Severity Index （DDNSI）， and the Epworth Somnolence Scale （ESS）. The objective sleep of the patients was assessed using polysomnography. The sleep electroencephalogram was filtered and the power spectral density of the brain wave was analyzed and processed for all the subjects. The subjective and objective sleep conditions of the two patient groups were compared， and the sleep electroencephalogram power spectral density of the patient groups and the control group were also compared. ResultsA comparison of subjective and objective sleep conditions between patients with depressive episode accompanied by suicidal behavior and patients with schizophrenia accompanied by suicidal behavior showed no statistically significant differences （P>0.05）. Comparisons of sleep electroencephalogram power spectral density in the W stage （average power of α wave， total power of δ wave， average power of δ wave， average power of θ wave）， N1 stage （average power of β wave， total power of α wave， total power of δ wave）， N2 stage （total power of α wave， average power of α wave， total power of δ wave， average power of δ wave）， N3 stage （average power of α wave， average power of δ wave）， and R stage （total power of α wave， average power of α wave， total power of δ wave， average power of δ wave） between patients with depressive episode accompanied by suicidal behavior， patients with schizophrenia accompanied by suicidal behavior， and the control group showed statistically significant differences （P<0.05 or 0.01）. The total power of δ wave in the W stage and the average power of β wave and δ wave in the N1 stage were higher in two patient groups were higher than those of the control group. The total power of α wave and the average power of α wave in the N2 stage were lower than those of the control group， while the average power of δ wave was higher than that of the control group. The average power of α wave in the N3 stage of both patient groups were lower than that of the control group， while the average power of δ wave was higher than that of the control group. The total power and average power of α wave in the R stage were lower than those of the control group， while the total power and average power of δ wave were higher than those of the control group. All the differences were statistically significant. Patients with depressive episode accompanied by suicidal behavior had higher average powers of α wave， δ wave， and θ wave in the W stage compared with the control group， while the total power of α wave in the N1 stage was lower in the former group. All these differences were statistically significant （P<0.05）. ConclusionThe depressive episode patients accompanied by suicidal behavior have highly overlapping sleep electroencephalogram abnormal patterns with those of schizophrenia patients， mainly manifested as a general decrease in α wave power （N2， N3， R stage） and a general increase in δ wave power （W， N1， N2， N3， R stage） as well as β wave power in N1 stage. At the same time， patients with depressive episode accompanied by suicidal behavior also show specific changes， including an increase in the average power of α and θ waves during the wakefulness period （W stage）， and a decrease in the total power of α wave in N1 stage. ［Funded by Guangdong Province High-level Clinical Key Specialty （with supporting funds from Shenzhen City） （number， SZGSP013）； Shenzhen Key Medical Discipline （number， SZXK041）； Shenzhen Clinical Medicine Research Center Project （number， 20210617155253001）］

"Weibing" is a fundamental concept in traditional Chinese medicine (TCM), representing a transitional state characterized by diminished self-regulatory abilities without overt physiological or social dysfunction. This perspective delves into the biological foundations and quantifiable markers of Weibing, aiming to establish a research framework for early disease intervention. Here, we propose the "Health Quadrant Classification" system, which divides the state of human body into health, sub-health, disease-susceptible state, and disease. We suggest the disease-susceptible stage emerges as a pivotal point for TCM interventions. To understand the intrinsic dynamics of this state, we propose laboratory and clinical studies utilizing time-series experiments and stress-induced disease susceptibility models. At the molecular level, bio-omics technologies and bioinformatics approaches are highlighted for uncovering intricate changes during disease progression. Furthermore, we discuss the application of mathematical models and artificial intelligence in developing early warning systems to anticipate and avert the transition from health to disease. This approach resonates with TCM's preventive philosophy, emphasizing proactive health maintenance and disease prevention. Ultimately, our perspective underscores the significance of integrating modern scientific methodologies with TCM principles to propel Weibing research and early intervention strategies forward.

ObjectiveTo observe the clinical efficacy of Tongfu Kuanzhong decoction （TFKZ） in the treatment of constipation-predominant irritable bowel syndrome （IBS-C） with spleen deficiency and Qi stagnation and its effects on anorectal manometry and colonic electrical activity parameters. MethodsSixty-four patients with IBS-C of the spleen deficiency and Qi stagnation type were included as research subjects and were randomized into the observation group （thirty-two cases） and control group （thirty-two cases）. The control group was orally administered mosapride citrate tablets， and the observation group was orally administered TFKZ. Both groups were treated for 4 weeks. The traditional Chinese medicine （TCM） syndrome scores， patient assessment of constipation symptoms （PAC-SYM） score， general anxiety disorder-7 （GAD-7） score， patient health questionnaire-9（PHQ-9）score， anorectal manometry， and colonic electrical activity parameters were observed before and after treatment in the two groups. ResultsThe total points of TCM syndromes were significantly lower in both groups after treatment （P<0.01） and lower in the observation group （P<0.05）. The fecal symptoms， rectal symptoms， abdominal symptoms， and total symptom scores of the patients in both groups were significantly decreased after treatment （P<0.01）， and the rectal symptoms， abdominal symptoms， and total symptom scores of the observation group were lower （P<0.05，P<0.01）. In both groups， the forced anal residual pressure and the initial rectal sensation threshold decreased after treatment （P<0.05，P<0.01）， and forced anal residual pressure in the control group was lower （P<0.01）. After treatment， the GAD-7 and PHQ-9 scores of patients in both groups decreased significantly （P<0.01）， and the GAD-7 score of the observation group was significantly lower （P<0.01）. After treatment， the average wave amplitude at different time points of each lead increased significantly in both groups， compared with that before treatment （P<0.01）. The average wave amplitude of each lead of the ascending colon， descending colon， sigmoid colon， and rectum in the observation group at 5 min before the meal and 10 min after the meal， as well as that of the ascending colon and rectum at 20 min and 30 min after the meal， was higher than that of the control group （P<0.05）. ConclusionTFKZ is effective in the treatment of IBS-C. Its mechanism may be related to the regulation of colonic function by down-regulating the forced anal residual pressure and the initial rectal sensation threshold and up-regulating the amplitude and frequency of intestinal electrical activity in each intestinal segment of the colon.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective To explore the efficacy and mechanism of the aqueous extract of Sauropus spatulifolius in treating constipation based on network pharmacology analysis and experiments.Meth-ods Network pharmacology analysis was conducted using an online platform to investigate the molec-ular mechanism of Sauropus spatulifolius in treating constipation.Loperamide-induced mouse consti-pation models and intestinal epithelial cell(IEC)injury models were constructed.Therapeutic effects were evaluated using indicators such as the time to the first black stool,fecal water content,and gas-trointestinal transit rate.Annexin V-FITC staining was used to assess apoptosis,JC-1 staining was used to detect mitochondrial membrane potential,chemiluminescence was used to measure adenosine triphosphate(ATP)levels,and western blotting was used to detect the expression of relevant proteins.Results Network pharmacology analysis revealed that 29 active components in Sauropus spatulifolius targeted 19 genes associated with constipation,with AKT1 identified as one of the key genes.Exper-imental results demonstrated that the aqueous extract of Sauropus spatulifolius effectively alleviated loperamide-induced constipation symptoms in mice,including weight loss,reduced intestinal motili-ty,prolonged defecation time,and decreased fecal water content.Additionally,the aqueous extract of Sauropus spatulifolius inhibited IEC-6 cell apoptosis,restored mitochondrial membrane potential,and maintained intracellular ATP levels.The therapeutic mechanism involved downregulating the ex-pression of Bel-2-associated X protein(Bax),cytochrome C,Cleaved-Caspase3,and aquaporin 3(AQP3),as well as enhancing protein kinase B(Akt)phosphorylation.Conclusion The aque-ous extract of Sauropus spatulifolius effectively ameliorates constipation symptoms in mouse models,and its mechanism may be related to improving intestinal cell energy metabolism,inhibiting IEC ap-optosis,and reducing AQP3 expression,suggesting that Sauropus spatulifolius could serve as a po-tential drug for the clinical treatment of constipation.

Objective:To evaluate the long-term effectiveness of lingual mucosal graft ureteroplasty (LMGU) for managing long-segment (≥5 cm) ureteral strictures in a multi-institutional cohort of patients.Methods:A multi-center retrospective case series study was conducted on clinical data from 42 patients undergoing LMGU for long-segment ureteral strictures (≥5 cm) across five institutions between February 2017 and June 2024. The cohort comprised 31 males and 11 females, with an age of (43.4±12.0) years (range: 15 to 64 years) and a body mass index of (24.6±2.6) kg/m2 (range: 16.0 to 30.0 kg/m2). Strictures involved the left ureter in 24 cases and right ureter in 18 cases, demonstrating a stricture length of (6.4±1.5) cm (range: 5.0 to 11.5 cm). Surgical interventions included either onlay ureteroplasty or augmented anastomotic ureteroplasty, selected according to intraoperative findings. Intraoperative parameters, postoperative complications, and follow-up outcomes were analyzed.Results:Laparoscopic surgery was performed in 22 cases and robot-assisted surgery in 20 cases. Among the 42 patients, 22 underwent onlay ureteroplasty while 20 received augmented anastomotic ureteroplasty. The graft length was (5.9±1.8) cm (range: 3.0 to 12.0 cm), operative time (191.5±55.6) minutes (range: 105.0 to 350.0 minutes), and intraoperative estimated blood loss (86.7±73.6) ml (range: 10.0 to 400.0 ml). All procedures were successfully completed without conversion to open surgery. The postoperative hospital stay was (7.6±2.0) days (range: 4.0 to 15.0 days), with double-J stent removal at 6 to 8 weeks postoperatively. During a follow-up of (49.1±25.0) months (range: 12.0 to 99.0 months), no stricture recurrence was observed in any patient.Conclusion:LMGU is a safe, feasible, and effective long-term technique for managing long-segment (≥5 cm) ureteral strictures.

OBJECTIVE To evaluate the efficacy and safety of letermovir in preventing cytomegalovirus(CMV)infection after allogeneic hematopoietic stem cell transplantation(allo-HSCT).METHODS A retrospective cohort study was conducted,enrolling patients who underwent allo-HSCT at the Department of Hematology,Shanghai General Hospital Affiliated to Shanghai Jiao Tong University School of Medicine,from August 30,2022,to February 21,2024.Patients who initiated letermovir prophylaxis within 28 days post-transplantation were assigned to the experimental group(99 cases),while those who did not initiate letermovir within this period were assigned to the control group(18 cases).The incidence and clinical characteristics of CMV infection(including the number of CMV infection cases,the number of cases progressing to CMV disease,recurrent CMV disease,onset time of CMV infection,and treatment duration),immune function recovery within 120 days post-transplantation,and the occurrence of transplantation-related complications(including CD4+and CD8+T-cell recovery,Epstein-Barr virus infection,acute graft-versus-host disease,human herpesvirus 6 infection,and posttransplant lymphoproliferative disorders)and adverse events were recorded.Univariate and multivariate Cox regression analyses were performed to identify factors influencing CMV infection.RESULTS A total of 117 patients were included,among whom 15 developed CMV infection,5 progressed to CMV disease,and 2 experienced recurrent CMV disease.The CMV infection rate in the experimental group was significantly lower than that in the control group(P＜0.001),and the onset time of CMV infection was significantly delayed(P=0.014).The proportion of patients with CD4+T-cell counts≥200 cells/μL in the experimental group was significantly lower than that in the control group(P=0.022).During the follow-up period,elevated creatinine levels were observed in 1 patient,and nausea and vomiting were observed in 2 patients.Multivariate Cox regression analysis revealed that the use of high-dose corticosteroids was a risk factor for CMV infection(HR=6.230,95%CI of 1.255-30.926,P=0.025),while initiating letermovir within 28 days post-transplantation was a protective factor(HR=0.125,95%CI of 0.045-0.348,P＜0.001).CONCLUSIONS Early initiation of letermovir after allo-HSCT significantly reduces the CMV infection rate and delays the onset of infection,with favorable short-term safety.

Objective:To assess the impact of preoperative Naples prognostic score on the prognosis of patients with hepatocellular carcinoma (HCC) after hepatic resection.Methods:Retrospective analysis was conducted on the data of 323 patients with HCC who underwent radical hepatectomy in Zhejiang Provincial People's Hospital from January 2012 to December 2017, including 281 males and 42 females, aged (56.6±11.3) years. All patients were divided into three groups according to their preoperative Naples prognostic scores: group A (0) ( n=37), group B (1-2) ( n=193), group C (3-4) ( n=93). Survival was analysed by the Kaplan-Meier method, and differences in survival were compared by the log-rank test. Univariate and multivariate Cox regression were used to analyse the effect of Naples prognostic score on prognosis. Results:The 1-, 3- and 5-year cumulative survival rates of HCC patients after hepatectomy were 91.9%, 78.4% and 68.3% in the A group, 89.1%, 76.1% and 64.4% in the B group, and 84.9%, 63.3% and 43.5% in the C group, respectively, and the cumulative survival rates showed a decreasing trend among the three groups, and the differences were statistically significant (all P<0.05). The recurrence-free survival rates at 1, 3 and 5 years after hepatectomy were 93.4%, 63.3% and 44.3% in the A group, 77.7%, 46.5% and 35.6% in the B group, and 64.1%, 41.1% and 28.2% in the C group, respectively, and the recurrence-free survival rates showed a decreasing trend among the three groups, and the differences were statistically significant (all P<0.05). On Cox multivariate analysis, patients with HCC of 3-4 had a higher risk of death after hepatic resection than those patients of 0 ( HR=2.011, 95% CI: 1.048-3.859, P=0.036), and the risk of postoperative recurrence was also higher than those patients of 0 ( HR=1.820, 95% CI: 1.081-3.066, P=0.024). Conclusion:Preoperative Naples prognostic score performs as a prognostic influence factor on survival and recurrence-free survival after hepatectomy in patients with HCC.
