Purpose This study aims to investigate the clinicopathological features of diffuse pulmonary menin-gotheliomatosis(DPM).Methods The clinical data of 10 patients with DPM undergoing video-assisted thoracic sur-gery(VATS)were collected,and their clinical and pathological characteristics were analyzed using immunohistochem-istry.Results The detection rate of DPM was 1.19‰,with 90％of the patients being female.DPM predominantly occurred in the age range of 40-60 years,with an average age at diagnosis of 50.7 years.Most patients had no smok-ing history.Pathological diagnosis combined with imaging findings was the main method for diagnosing DPM.80％of the patients were prone to concurrent early-stage invasive pulmonary adenocarcinoma.Laboratory indicators,including pulmonary function,were generally normal.Chest CT showed diffuse multiple ground-glass opacity or cystic nodules in both lungs,with the number of nodules in both lungs ranging from dozens to hundreds,and the maximum diameter of the nodules was 2-6 mm.The median volume and CT value of the pulmonary nodules were 35.32 mm3 and-566 HU,respectively.Pathological features mainly included multiple meningothelial-like nodules observed under the micro-scope.Immunophenotypically,CD56,EMA,PR,and vimentin were often positive.Conclusion DPM is a rare lung disease with no obvious clinical symptoms,and is more common in middle-aged and elderly women.Diffuse multiple nodules in both lungs are its main imaging features.Most DPM patients are complicated with lung adenocarcinoma,and regular follow-up is recommended.

Objective:To evaluate the clinical efficacy of endoscopic treatment of superficial non-ampullary duodenal adenoma.Methods:A retrospective analysis was performed on the clinical data and follow-up information of patients diagnosed with superficial duodenal non-ampullary adenomas via preoperative endoscopy and treated endoscopically at Peking University First Hospital between January 2013 and January 2024. The overall en bloc resection rate, complete resection rate of the lesion, perioperative complications, and recurrence rates were evaluated. Patients were categorized into three groups based on their treatment modality: endoscopic mucosal resection (EMR)（ n=46）, endoscopic submucosal dissection (ESD)（ n=16）, and modified ESD (ESD with snare, ESD-S)（ n=24）. Comparative analyses were conducted to evaluate operative time, en bloc resection rate, and complete resection rate among the three groups. Results:Among 86 patients, the overall en bloc and complete resection rates were 87.2% (75/86) and 86.0% (74/86), respectively. No case of delayed bleeding was observed during the perioperative period. Intraoperative perforation occurred in two patients, both of whom improved following conservative management. Delayed perforation was noted in four patients, and three of them were successfully managed with surgical intervention, while one case was resolved after conservative treatment. During the follow-up period, local recurrence was identified in two patients. Following re-treatment with endoscopy and continuous surveillance, no further recurrence was observed. The operative times for the EMR group, ESD-S group, and ESD group were 4 (1-36) minutes, 25 (5-190) minutes, and 46 (5-150) minutes, respectively. Significant differences were observed in operative times among the three groups ( Hc=49.892, P<0.001). The en bloc resection rates for the EMR, ESD-S, and ESD groups were 80.4% (37/46), 91.7% (22/24), and 100.0% (16/16), respectively. The complete resection rates were 80.4% (37/46), 91.7% (22/24), and 93.8% (15/16) for the respective groups. Conclusion:Endoscopic treatment demonstrates favorable efficacy and safety for superficial non-ampullary duodenal adenoma. In addition to traditional EMR and ESD, ESD-S is also an effective procedure for endoscopic treatment of non-ampullary duodenal adenoma.

ObjectiveTo explore the establishment of performance assessment indicators for the classification and grading of public health staff in district-level Centers for Disease Control and Prevention (CDCs), and to provide a basis for such evaluations. MethodsThrough literature review and group interviews, performance evaluation indicators were developed based on competency evaluation. Experts were invited to evaluate the weight of performance evaluation indicators for public health staff from different categories, with the average value used to represent the weight of each indicator. ResultsTwenty-nine experts from universities in Shanghai, municipal CDCs, and district CDCs participated, yielding an expert authority coefficient of 0.86. The performance evaluation indicators for department managers were categorized into three levels, with 4 indicators at the primary level, 16 indicators at the secondary level, and 42 indicators at the tertiary level, while those for general staff included 4 primary indicators, 15 secondary indicators, and 36 tertiary indicators. Significant differences were observed in the weight coefficients of the primary indicators (internal operations, professional work, and learning and growth) between department managers and general staff. The top three secondary indicators for department managers were department management, monitoring and prevention, and level of expertise. For mid-level and senior staff, the top three secondary indicators were monitoring and prevention, level of expertise, and research work. The top three secondary indicators for junior staff were monitoring and prevention, professional expertise, and professional attitude. No significant statistical differences were found among tertiary indicators. ConclusionThe developed performance evaluation indicators are reliable. Staff at different levels and classifications should be evaluated using different performance evaluation standards to accurately reflect individual performance and contributions.

AIM: To compare the clinical efficacy, vault, and rotational stability of horizontal, oblique, and vertical implantation of Toric implantable collamer lens(TICL).METHODS: Retrospective cohort study. A total of 92 cases(120 eyes)who underwent TICL implantation from July 2018 to March 2022 and had regular follow-up for at least 1 a postoperatively(1 d, 1 wk, 1, 3, 6 mo, and 1 a)at Wuhan Bright Eye Hospital were collected. The patients were divided into three groups, with 34 cases(45 eyes)in horizontal implantation group, 25 cases(29 eyes)in oblique implantation group(29 cases), and 33 cases(46 eyes)in vertical implantation group. Uncorrected distance visual acuity(UDVA), corrected distance visual acuity(CDVA), diopters, vault, and rotation angle(deviation of the actual axis of TICL from the expected axis).RESULTS: All surgeries were uneventful, and there were no complications such as infection, secondary glaucoma, or cataract opacity. Safety and efficacy of the surgery: the CDVA of the three groups of patients was better than or equal to the preoperative CDVA at 1 a postoperatively, and there was no statistically significant differences in postoperative UDVA and CDVA of the three groups(P>0.05). The safety index at 1a postoperatively was 1.34±0.21, 1.34±0.17, and 1.31±0.18 for the horizontal, oblique, and vertical groups, respectively. The efficacy index was 1.26±0.21, 1.33±0.18, and 1.27±0.16 for the three groups, respectively, both with no statistically significant differences(P>0.05). Vault: there was a significant difference in postoperative vault among the three groups(P=0.003), with the vertical group having the lowest vault, followed by the horizontal group and the oblique group. The vaults at different follow-up time points within each group showed significant differences(P<0.001), and all decreased over time. Residual astigmatism: there was no significant difference in residual astigmatism among the three groups(P=0.130), but there were differences at different follow-up time points within each group(P<0.001). Rotation angle: no significant differences in rotation angle were observed among the three groups(P=0.135), but there were differences at different follow-up time points within each group(P<0.001).CONCLUSION: The implantation of TICL in different orientations has good safety and efficacy, the postoperative rotational stability is good, and the appropriate angle can be selected to implant TICL according to the clinical situation.

Objective To investigate the trends of major thyroid function indices in Chinese adolescent females at different ages and the differences from adult reference intervals.Methods A total of 791 female students from 4 junior high schools were enrolled in the study by selecting one junior high school in each of the following locations:Minhang District of Shanghai,Haimen City of Jiangsu Province,Yuhuan City of Zhejiang Province,and Deqing County of Zhejiang Province from Oct to Nov 2017 and from Jan to Mar 2019.The subjects were subjected to physical examination as well as thyroid hormone levels;and the Pubertal Developmental Events Self-Assessment Scale(PDS)was used to evaluate the staging of pubertal development.Follow-ups were conducted after 2 years,with the same survey content.Thyroid function levels were assessed in 5 age groups between 11 to 15 years old,95%CI were calculated,and mixed linear models were used to analyze the effects of age and pubertal developmental stage on hormone levels.Results The reference intervals for thyroid stimulating hormone(TSH),free triiodothyronine(FT3)and free thyroxine(FT4)in adolescent females differed significantly from those of adults,with misclassification rates ranging from 2.98%to 5.17%.Statistically significant differences were found for age,pubertal development staging,and the interaction of age and pubertal staging after correcting for BMI,waist circumference(all P<0.05).TSH levels were more affected by age before the completion of pubertal development,the level of the 12-year-old group was higher than that of the 11-year-old group(P=0.001 2)and the 13-year-old group(P<0.000 1);FT3 levels showed greater variability with age during late pubertal stage,with levels significantly higher at 13 years of age than at 11 and 12 years of age(P<0.0001),and gradually decreasing after 13 years of age(P<0.000 1).In contrast,FT4 levels were generally less affected by age between 11 and 15 years of age,with levels slightly higher at 13-15 years of age than at 11-12 years of age(P<0.000 1).Conclusion The levels of TSH,FT3,and FT4,as indicators of thyroid function in adolescent females,differ significantly from those of adults,and are differently affected by age and the stages of pubertal development;further refinement of the reference intervals for age-and pubertal-development-specific thyroid indicators is necessary.

Objective To construct trajectory models of care-seeking patterns for type 2 diabetes mellitus(T2DM)patients,analyze the influencing factors of different trajectories,and explore the fasting blood glucose control levels of T2DM patients with different trajectories.Methods A retrospective cohort study was carried out on 18088 T2DM patients who had health records and been involved in the diabetic management in Community Health Service Center of Minhang District,Shanghai from 2006 to 2009.Starting from Jan 1,2010,participants were followed up until Dec 31,2019,with complete follow-up information.Group-based trajectory modelling(GBTM)was employed to identify and construct the fluctuation trajectory of fasting blood glucose in the patients.Bayesian information criterion(BIC),average posterior probability(AvePP)and other evaluation indicators were used to select the optimum subgroup number model.Then the differences in demographic characteristics,health status,family history,fasting blood glucose,BMI,etc were compared among different categories.Multinational logistic regression model was constructed to explore the influencing factors of different fluctuation trajectories.Cox regression analysis was used to examine the relationship between the long-term trajectories of care-seeking patterns and fasting blood glucose control level.Results Using GBTM analysis,we constructed the optimal Model 4 to categorize 18088 T2DM patients with community health records into five distinct trajectory subgroups:continuous non-attendance group(22.29%),low-level increasing group(15.09%),high-level slowly decreasing group(14.18%),high-level rapidly decreasing group(14.90%),and continuous regular attendance group(33.54%).With the continuous regular attendance group serving as the reference,gender,age,place of residence,baseline comorbidity of hypertension,baseline fasting plasma glucose level,and BMI were found to influence the community attendance trajectories of T2DM patients(P<0.05).After adjusting for confounding factors,Cox regression analysis revealed that compared to the continuous non-attendance group,the low-level increasing group,high-level slowly decreasing group,and continuous regular attendance group had better glycemic control,with HRs of 0.37(95%CI:0.34-0.39),0.72(95%CI:0.67-0.78),and 0.78(95%CI:0.73-0.84),respectively.The glycemic control level in the high-level rapidly decreasing group was comparable,with an HR of 1.06(95%CI:0.99-1.12).Conclusion Based on the optimal model,the community medical treatment trajectories of T2DM patients showed different dynamic characteristics.Factors such as gender,residence,hypertension,and weight loss may influence these varying trajectories.Regular community visits and follow-up may help control blood glucose levels.

Epigenomic imbalance drives abnormal transcriptional processes,promoting the onset and progression of cancer.Although defective gene regulation generally affects carcinogenesis and tumor suppression networks,tumor immunogenicity and immune cells involved in antitumor responses may also be affected by epigenomic changes,which may have significant implications for the development and application of epigenetic therapy,cancer immunotherapy,and their combinations.Herein,we focus on the impact of epigenetic regulation on tumor immune cell function and the role of key abnormal epigenetic processes,DNA methylation,histone post-translational modification,and chromatin structure in tumor immunogenicity,and introduce these epigenetic research methods.We emphasize the value of small-molecule inhibitors of epigenetic modulators in enhancing antitumor immune responses and discuss the challenges of developing treatment plans that combine epigenetic therapy and immuno-therapy through the complex interaction between cancer epigenetics and cancer immunology.

OBJECTIVE To compare the cost-utility of eight programmed death 1(PD-1)/programmed cell death-ligand 1(PD-L1) inhibitor combination regimens for first-line treatment of advanced non-small cell lung cancer(NSCLC) from the perspective of Chinese healthcare system. METHODS Relevant data were derived from a published network meta-analysis and randomized controlled trails, a three-state Markov model was established to analyze the cost-utility of eight immunotherapy combinations. The robustness of results were validated through sensitivity analyses and a series of scenario analyses was also conducted. RESULTS The incremental cost-utility ratio(ICUR) of the sintilizumab plus chemotherapy group and the tislelizumab plus chemotherapy group were ￥125143.88/quality adjusted life year(QALY) and ￥189609.64/QALY, respectively, which were less than the willingness-to-pay(WTP) threshold of ￥257094/QALY, and all the ICURs of other PD-1/PD-L1 inhibitor combination regimens exceeded the WTP threshold and were not economical. Scenario analyses found that even if the medical insurance reimbursement ratio reached 80%, the different combinations of pembrolizumab, nivolumab and atezolizumab were not economical. CONCLUSION Compared with other PD-1/PD-L1 inhibitor combination regimens, sintilizumab plus chemotherapy and tislelizumab plus chemotherapy have cost-utility advantages in the first-line treatment of advanced NSCLC, which can provide a certain reference for selecting a reasonable treatment plan for NSCLC patients.
