To summarise the clinical experience of treating insomnia with the method of resolving depression， regulating the middle， and tranquilising mind. It is believed that the key to the pathogenesis of insomnia lies in qi depression， disharmony of qi pivot， and disharmony of qi and blood， and the core treatment is to resolve depression， regulating the middle， and tranquilising mind. The self-prescribed Jieyu Anmian Formula （解郁安眠方） could be used as the basic treatment， then modified according to the performance of the patient and syndromes. For syndrome of liver depression restricting spleen， the treatment should soothe liver and invigorate spleen， resolve depression and regulate the middle； for syndrome of liver depression and phlegm coagulation， the treatment should resolve depression and phlegm， support the earth and free the wood； for syndrome of liver depression transforming into fire， the treatment should soothe liver and clear fire， resolve depression and dysphoria； for syndrome of qi stagnation and blood stasis， the treatment should activate blood and regulate the middle， resolve depression and tranquilise mind.

Esophageal scar stenosis following chemical burns is a common and complex clinical issue.According to the Zargar classification,approximately 90％of patients with third-degree burns and 15％-30％of those with second-degree burns will develop esophageal or pyloric stenosis.Personalized treatment strategies tailored to the specifics of esophageal stenosis are particularly important.This review focuses on the selection of anastomotic sites during esophageal reconstruction following chemical burns and summarizes perioperative evaluations and timing of surgery.Overall,the treatment strategy for esophageal scar stenosis emphasizes personalized medicine,taking into account the characteristics of the stenosis and carefully selecting the most suitable surgical approach to achieve optimal therapeutic outcomes.

ObjectiveTo compare colonoscopy compliance rates under different screening strategies, to explore ways to enhance colonoscopy compliance among residents with colorectal carcinoma. MethodsResidents aged between 50‒80 years were recruited through extensive community outreach and voluntary participation. A total of 210 630 residents who participated in the colorectal carcinoma screening program in Jiading District, Shanghai, between 2013 and 2019 were selected as the research subjects. All subjects underwent a colorectal carcinoma risk assessment questionnaire survey and two fecal occult blood tests (FOBT). Positive results in the initial screening were defined as a positive questionnaire survey or a positive result in at least one FOBT. Participants with positive initial screening results were advised to undergo colonoscopy screening in a hospital. Colonoscopy results were collected from hospital reports and physician follow-ups. Compliance with colonoscopy was analyzed under different screening strategies to identify possible factors influencing residents’ willingness to undergo the procedure. ResultsA total of 21 403 individuals (10.16%) were identified as positive with the questionnaire survey, 31 595 individuals (15.00%) tested positive with at least one FOBT. Combined questionnaire and FOBT positivity was observed in 3 501 individuals (1.66%). Among the 48 453 individuals with positive initial screening results, 17 230 (35.56%) underwent colonoscopy, and a total of 315 cases of colorectal cancer were detected. The sensitivity, specificity value of FOBT initial screening were 83.81% and 84.66%, respectively. According to the combined risk assessment and FOBT initial screening preliminary screening, the lowest colonoscopy compliance rate (25.63%) was observed among individuals with only a positive questionnaire, and the highest compliance rate (52.55%) was among those with both positive questionnaire survey and two positive FOBT results. Multivariate analysis revealed that FOBT positivity had the greatest impact on colonoscopy compliance. Those with one positive FOBT test result were 2.64 times more likely to undergo colonoscopy screening than those with negative FOBT results, while individuals with two positive FOBT results were 3.18 times more likely to do so. After adjusting for FOBT results, individuals with positive questionnaire survey results were 1.43 times more likely to undergo colonoscopy screening than those with negative results (95%CI: 1.34‒1.52). Compared to questionnaire-based risk assessment, FOBT results were more influential in determining compliance with colonoscopy. ConclusionThe choice of initial screening method significantly impacts residents’ compliance with colonoscopy. While implementing colorectal carcinoma screening programs, it is necessary to strictly adhere to screening protocols, including risk assessment and FOBT. Additionally, efforts should be made to raise public awareness, encouraging residents to actively participate in risk assessments and FOBT, thereby improving their compliance with colonoscopy.

Background and Aims:Tumor deposits(TDs)may influence prognosis beyond the current 8th edition AJCC pTNM nodal classification in gastric cancer(GC).This study investigates the prognostic value of TD number and proposes an improved pN staging(mpN)that classifies patients with TD number>1 as pN3b.We validated the mpN staging against the 8th AJCC pN staging.Methods:A dual-center retrospective cohort study was performed,including 1 327 patients who underwent radical gastrectomy at Sun Yat-sen University Cancer Center(2011-2015;test cohort)and 340 patients from Guangdong Provincial People's Hospital(2015-2022;validation cohort).Patients were dichotomized into low-TD(≤1)and high-TD(>1)groups.Outcomes were overall survival(OS)and disease-free survival(DFS).Survival analyses used Kaplan-Meier curves,IPTW,and Cox regression.Predictive performance of staging systems was assessed by time-dependent ROC(tROC)/tAUC,concordance index(C-index)and Akaike information criterion(AIC).Results:TDs were present in 435/1 327(32.7%)in the test cohort.Presence of TD was associated with worse OS(IPTW-adjusted HR=2.69,95%CI=2.18-3.31,P<0.01)and DFS(HR=2.82,95%CI=2.32-3.42,P<0.01).In multivariable models,TD remained an independent adverse factor for OS(HR=1.65,95%CI=1.34-2.05;P<0.01)and DFS(HR=1.74,95%CI=1.43-2.11,P<0.01).Increasing TD number correlated with progressively poorer survival;X-tile identified>1 as an optimal cutoff,with high-TD patients showing markedly worse outcomes(OS:adjusted HR=3.65,95%CI=2.74-4.88;DFS:adjusted HR=3.74,95%CI=2.85-4.91;both P<0.01).Incorporation of TD number into the mpN staging(assigning TD>1 to pN3b)improved prognostic discrimination:in the test cohort 5-year OS tAUC was 0.746 for mpN vs.0.703 for AJCC pN(C-index 0.738 vs.0.721,AIC 5 805.27 vs.5 849.30);similar improvements were observed in the validation cohort.Conclusion:TD presence and number exert significant negative prognostic impact in GC.Classifying patients with TD number>1 as pN3b enhances prognostic accuracy.Routine reporting of TD counts and further prospective multicenter validation of mpN staging are warranted.

This study analyzed the clinical characteristics,diagnosis,treatment,and outcomes of disseminated Tsalaromycosis marneffei(DTSM)in non-HIV-infected patients.A retrospective analysis was conducted on 20 cases of non-HIV-infected DTSM treated at Guangzhou Chest Hospital between January 2015 and December 2021.Clinical data,including demographic characteris-tics,time to diagnosis,clinical manifestations,comorbidities,treatment details,and outcomes,were collected and analyzed.Among the 20 cases,9 were in males,and 11 were in females;the median age was 46(range:1-70)years.The median time from symptom onset to definitive diagnosis was 12(range:1-24)months,and 16 cases were initially misdiagnosed with mycobacterial disease.More than half the patients exhibited four major clinical features:fever,lymphadenopathy,skin lesions,and bone lesions.Pulmonary imag-ing abnormalities were observed in 19 cases,and an average of(3.6±1.6)lung lobes were involved.The positive detection rate of multi-sample cultures(70%,14/20)was significantly higher than that identified through histopathological examination(25%,5/20)(χ2=8.120,P=0.004).Findings for all five patients with positive next-generation sequencing(NGS)results were further confirmed through pathogen culture or histopathology.After antifungal treatment,14 patients showed clinical improvement and were discharged.In conclusion,non-HIV-infected DTSM is characterized by complex clinical manifestations and extensive pulmonary involvement,thus leading to frequent misdiagnosis and diagnostic delays.Pathogen detection methods,such as multi-sample cultures and NGS,demonstrate superior diagnostic accuracy to histopathological examination.Early identification and standardized antifungal therapy are critical factors in determining patient outcomes.

Objective The study aimed to compare the efficacy and safety of tislelizumab combined with chemotherapy versus pembrolizumab combined with chemotherapy as first-line treatments for advanced lung squa-mous cell carcinoma.Methods We retrospectively reviewed and analyzed the medical records of 116 patients with advanced lung squamous cell carcinoma treated with first-line chemotherapy plus tislelizumab or pembrolizumab in Guangzhou Chest Hospital from September 2020 to April 2024.We focused on analysis of time to treatment failure(TTF)and objective response rate(ORR)as well as disease control rate(DCR)and treatment-related adverse events(TRAEs).Results At a median follow up of 19.7 monyhs,the median TTF was 9.7 months in the tislelizumab group and 7.7 months in the pembrolizumab group(P<0.05).In addition,the ORR in the tislelizumab group was significantly higher than that in the pembrolizumab group(77.6%vs.60.3%,P<0.05),with DCRs of 93.1%and 87.9%,respectively(P=0.342).Regarding safety,the proportions of grade 3 or higher TRAEs and any-grade TRAEs were comparable between the two groups:29.3%and 81.0%in the tislelizumab group,and 32.8%and 87.9%in the pembrolizumab group,respectively.The most common TRAEs in both groups were hematological toxicities.Conclusions Tislelizumab plus chemotherapy demonstrated better efficacy and safety compared to pembrolizumab with chemotherapy as first-line treatment for Chinese patients with advanced lung squamous cell carcinoma.

Objective:To evaluate the safety and efficacy of combined inflatable mediastinoscopy with laparoscopy guided by the concept of “reduced field and port” during esophagectomy for esophageal cancer.Methods:This is a retrospective cohort study. The clinical data of 497 patients with esophageal squamous cell carcinoma who underwent minimally invasive esophagectomy at the Center of Minimally Invasive Thoracic Surgery, the Second Affiliated Hospital of Naval Medical University, between January 2017 and December 2024 were retrospectively analyzed. There were 416 male and 81 female patients, with an age of (68.3±8.0) years (range: 44 to 89 years). Patients were divided into the traditional video-assisted thoracoscopic surgery group (Group A, n=354) and the combined inflatable mediastinoscopy with laparoscopic surgery group(Group B, n=143) based on the surgical approach. Furthermore, Group B was subdivided into the multiport laparoscopic group (Group B1, n=81) and the single-incision laparoscopic surgery plus one port group (Group B2, n=62). Perioperative indicators and postoperative survival differences were compared between the groups. Inter-group comparisons were performed using the independent sample t-test, χ2 test, or Fisher′s exact probability test. Survival curves were plotted using the Kaplan-Meier method, and the Log-rank test was used to analyze the survival differences between groups. Results:Compared with Group A, Group B demonstrated a significantly shorter operative time ((181.8±11.4) minutes vs. (196.7±8.1)minutes, t=16.09, P<0.01), a lower incidence of postoperative pulmonary complications (8.4% (12/143) vs. 17.8% (63/354), χ2=6.27, P=0.012), lower perioperative mortality (0 vs. 3.1%(11/354), P=0.039), and a shorter postoperative hospital stay ((16.2±2.2)days vs. (18.9±4.1)days, t=8.56, P<0.01). There was no significant difference in the anastomotic leak rate, number of lymph nodes dissected, or intraoperative blood loss between the two groups (all P>0.05). Overall survival time and recurrence-free survival time showed no significant difference between the two groups (all P>0.05). Subgroup analysis revealed no significant differences in perioperative indicators or postoperative complication rates between Group B1 and Group B2. Conclusions:Compared with traditional thoracoscopic combined with laparoscopic surgery, inflatable mediastinoscopy offered advantages in terms of lower postoperative pulmonary complication rates, shorter operative time, reduced postoperative hospital stay, and lower perioperative mortality. The “reduced field and port” concept could further minimize surgical trauma during the transmediastinal approach for esophagectomy while ensuring surgical safety and efficacy.

Objective:To investigate the differential effects of proton FLASH irradiation and conventional dose rate (CONV) irradiation on human normal liver cells WRL68 and human hepatocellular carcinoma cells HepG2.Methods:Using a 100 MeV high-current proton cyclotron accelerator, WRL68 and HepG2 cells were subjected to CONV (0.8 Gy/min) and FLASH (40 Gy/s) irradiation with 4 Gy protons. After irradiation, changes in cell proliferation, apoptosis, and cell cycle arrest were detected at different time points. Additionally, transcriptome sequencing was employed to analyze alterations in the gene expression profiles of the two cell lines.Results:For WRL68 cells, compared with CONV irradiation, proton FLASH irradiation enhanced cell proliferative activity ( t=10.18-16.67, P<0.05), reduced the apoptotic rate ( t=3.21-8.30, P<0.05), and decreased the proportion of cells arrested in the G 2 phase at the same time points ( t=34.08-65.16, P<0.05). In contrast, for HepG2 cells, proton FLASH irradiation significantly inhibited cell proliferation ( t=2.57-9.39, P<0.05), increased the apoptotic rate ( t=3.25-66.70, P<0.05), and similarly induced cell cycle arrest predominantly in the G 2 phase ( t=10.87-27.47, P<0.05). Transcriptome sequencing identified 906 differentially expressed genes (DEGs) between the FLASH group and the CONV group in WRL68 cells, and 1 243 DEGs were detected in HepG2 cells. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses of these DEGs suggested that cellular adhesion and oxygen effect may serve as crucial microscopic mechanisms underlying FLASH radiotherapy. Conclusions:Under proton FLASH irradiation, the radiation-induced damage to human normal liver cells was significantly alleviated, whereas the damage to hepatocellular carcinoma cells was aggravated. The identified DEGs are involved in multiple radiobiological functional pathways.
