ObjectiveTo explore the possible mechanism of the Yiqi Jiedu formula (YQ) in treating ischemic stroke (IS) from the perspective of the microbial-gut-brain axis (MGBA). MethodRats were randomly divided into five groups, with six in each group, including sham surgery group, model group, and low, medium, and high dose YQ groups (1, 5, and 25 mg·kg-1). Except for the sham surgery group, all other groups were established with a middle cerebral artery occlusion (MCAO) model using the thread occlusion method. The success of modeling was determined through neurobehavioral scoring, and the protective effect of YQ on IS was evaluated. Then, the changes in gut microbiota before and after MCAO modeling and YQ administration were compared using 16S rDNA sequencing technology, and the possible biological pathways related to the effect of this formula were analyzed. The expression of inflammatory factors such as interleukin-6 (IL-6), interleukin-17A (IL-17A), and interleukin-10 (IL-10) in serum was detected by enzyme-linked immunosorbent assay (ELISA). Western blot was used to detect the expression of tight junction proteins ZO-1 and Occludin in brain and intestinal tissue, and hematoxylin-eosin staining (HE) was used to observe pathological changes in the cerebral cortex and colon, so as to validate the possible mechanism of action. ResultYQ significantly improved the neurobehavioral score of MCAO rats (P<0.01) and played a good regulatory role in intestinal microbial disorders caused by enriched pathogens and opportunistic pathogens during the acute phase. Among them, significantly changed microorganisms include Morgentia, Escherichia Shigella, Adlercreutzia, and Androbacter. Bioinformatics analysis found that these bacteria may be related to the regulation of inflammation in the brain. Compared with the blank group, the detection of inflammatory factors in the serum of IS model rats showed an increase in inflammatory factors IL-6 and IL-17A (P<0.01) and a decrease in the content of anti-inflammatory factor IL-10 (P<0.01). Compared with the model group, the content of inflammatory factors IL-6 and IL-17A in the serum of the treatment group decreased (P<0.05), and that of anti-inflammatory factor IL-10 increased (P<0.01). The expression results of barrier proteins ZO-1 and Occludin in brain and intestinal tissue showed that the expression levels of both decreased in IS model rats (P<0.05), while the expression levels of both increased in the treatment group (P<0.05). ConclusionAcute cerebral ischemia can lead to an imbalance of intestinal microbiota and damage to the intestinal barrier, and it can increase intestinal permeability. YQ can regulate intestinal microbiota imbalance caused by ischemia, inhibit systemic inflammatory response, and improve the disruption of the gut-blood brain barrier, preventing secondary cascade damage to brain tissue caused by inflammation. The MGBA may be an important mechanism against the IS.

Objective:
To analyze the results of colorectal cancer screening among residents in Baoshan District, Shanghai Municipality from 2013 to 2021, so as to provide the basis for promoting colorectal cancer screening and prevention.
Methods:
Permanent residents aged 50 to 74 years in Baoshan District from 2013 to 2021 were selected as the screening population. The initial screening was conducted using a risk assessment form and fecal occult blood test. Positive results on either the risk assessment form or fecal occult blood test were considered positive for the initial screening. Participants with positive initial screening results were invited to undergo colonoscopy. The positive rate of the initial screening, colonoscopy compliance rate, and colonoscopy results were analyzed.
Results:
A total of 264 907 individuals underwent the initial colorectal cancer screening in Baoshan District from 2013 to 2021, with 65 333 individuals (24.66%) testing positive. Among them, the positive rate of the risk assessment form was 12.16%, and the positive rate of fecal occult blood test was 14.64%. A total of 14 473 individuals completed colonoscopy, with a compliance rate of 22.15%. A total of 1 284 precancerous lesions were detected, with a detection rate of 8.87%, and 386 cases of colorectal cancer were identified, with a detection rate of 2.67%. The positive rate of the initial screening, colonoscopy compliance rate, precancerous lesion detection rate, and colorectal cancer detection rate were higher in males than in females (25.55% vs. 24.06%, 23.12% vs. 21.45%, 11.60% vs. 6.74%, 3.62% vs. 1.93%, all P<0.05). With increasing age, the positive rate of the initial screening increased, the colonoscopy compliance rate decreased, the precancerous lesion detection rate and colorectal cancer detection rate increased (all P<0.05). From 2013 to 2021, the positive rate of the initial screening among residents showed a downward trend, while the colonoscopy compliance rate showed an upward trend (both P<0.05).
Conclusions
The detection rate of precancerous lesions in colorectal cancer was 8.87%, and the detection rate of colorectal cancer was 2.67% in Baoshan District from 2013 to 2021. Male and older individuals were the key populations for screening, and the colonoscopy compliance among residents needs to be improved.

Objective:To analyze the image characteristics of gastrointestinal stromal tumor(GIST) and leiomyoma under white-light endoscopy and ultrasound endoscopy, so as to establish a nomogram model and to validate its performance.Methods:From August 1, 2019, to December 1, 2022, the clinical data of 224 patients with GIST or leiomyoma who underwent endoscopic ultrasound examination at the First Affiliated Hospital of Soochow University were retrospectively analyzed. The 224 patients were divided into the modeling group of 145 cases (78 cases of GIST and 67 cases of leiomyoma), and the validation group of 79 cases (41 cases of GIST and 38 cases of leiomyoma). The basic data of patients, parameters of white-light endoscopy and ultrasound endoscopy were screened to establish a binary logistic regression model and draw a nomogram. The receiver operating characteristic curve (ROC) was drawn, and the area under the curve (AUC) was used to evaluate the diagnostic efficiency of the model, and calibration curve was used to evaluate the consistency of predicted and observed probabilities. The model′s performance was compared with the diagnostic results of junior physicians (attending physicians) and senior physicians (associated chief physician). Decision curve analysis (DCA) was performed to evaluate the net benefit of the model. Independent sample t-test and chi-square test were used for statistical analysis. Results:Under white-light endoscopy, there were statistically significant differences in the lesion locations (esophagus: 0 vs. 56.7% (38/67); cardia: 11.5% (9/78) vs. 13.4% (9/67); gastric: 88.5% (69/78) vs. 29.9% (20/67)) and tumor morphyology (spherical or spheroid: 80.8% (63/78) vs. 28.4% (19/67); shuttle: 19.2% (15/78) vs. 71.6% (48/67)) between GIST and leiomyoma in the modeling group ( χ2=64.51 and 46.37, both P<0.001). Under ultrasound endoscopy, the proportion of patients with GIST whose lesions originated from the muscularis propria layer, with indistinct borders and with internal hyperechoic area were all higher than those of patients with leiomyoma (96.2% (75/78) vs. 62.7% (42/67); 53.8% (42/78) vs. 13.4% (9/67); 35.9% (28/78) vs. 10.4% (7/67)), and the differences were statistically significant ( χ2=25.91, 25.82 and 12.75, all P<0.001). Based on the logistic regression model, a nomogram model was established with age, tumor morphology, lesion origin, boundary clarity, and hyperechoic foci as predictive indicators. In the modeling group, the accuracy of nomogram model in the diagnosis of GIST and leiomyoma was 89.7% and 83.6%, respectively. In the validation group, the sensitivity, specificity, and accuracy in GIST and leiomyoma diagnosis of the nomogram model and senior physicians were all higher than those of junior physicians in differentiating GIST from leiomyoma (90.2%, 87.8% vs. 82.9%; 81.6%, 84.2% vs. 78.9%; 86.1%, 86.1% vs. 81.0%, respectively), and the sensitivity, specificity, and accuracy of the nomogram model were equal to those of senior physicians in differentiating GIST from leiomyoma. The AUCs of the nomogram model in the modeling group and validation group were 0.932 (95% confidence interval 0.891 to 0.974) and 0.916 (95% confidence interval 0.854 to 0.978), respectively. The calibration curves of the model indicated that the consistency between the predicted probabilities and observed probabilities was good, and DCA suggested good clinical net benefits of the model. Conclusion:The model exhibits good test efficiency, discrimination, prediction consistency and clinical net benefit when age, tumor morphology, lesion origin, boundary clarity, and hyperechoic foci are selected as indicators.

MethodsThe death surveillance data of Baoshan District from 2009 to 2021 were collected from the Shanghai chronic disease surveillance information management system. Crude mortality, standardized mortality,potential years of life lost (PYLL), potential years of life lost rate (PYLLR) , average years of potential life lost (AYLL) , annual percentage change (APC) were calculated to analyze the trend of mortality and life loss of pancreatic cancer. ResultsFrom 2009 to 2021, a total of 2117 deaths of pancreatic cancer were reported in Baoshan District, accounting for 7.05% of all cancer deaths. The average age of the death cases was (71.18±10.97)years. The youngest was 3 years old and the oldest was 96 years old. The death component ratio of pancreatic cancer increased with time (P<0.05), and the average death age of women was higher than that of men (P<0.05). The crude mortality of pancreatic cancer was 17.38/105 in Baoshan District from 2009 to 2021, showing a rising tendency (P<0.05) with APC of 3.74%. The standardized mortality of pancreatic cancer was 7.84/105. The crude mortality of pancreatic cancer was 19.71/105 in men and 14.89/105 in women, both showed a tendency towards a rise (P<0.05 ) with APC of 4.44% and 2. 89%, respectively. The crude mortality of pancreatic cancer showed a tendency towards a decline in residents at ages of 45 to 60 years ( P<0.05 ), with APC of 4.74%. The PYLL and PYLLR of pancreatic cancer were 8 115 person-years and 0.67‰ in Baoshan District from 2009 to 2021, while the AYLL of pancreatic cancer was 3.83 years per person. The PYLL was higher in men than in women. ConclusionThe mortality rate of pancreatic cancer in Baoshan District shows an increasing trend. The healthy life of elderly and men is affected largely by pancreatic cancer. It is necessary to strengthen the health education on the prevention/control of pancreatic cancer and healthy life style, thereby improving the tertiary prevention system of pancreatic cancer.

ObjectiveTo investigate the monitoring status and epidemiological characteristics of foodborne disease pathogens in Baoshan District, Shanghai so as to improve early detection and warning capabilities of foodborne diseases outbreaks, and to provide a scientific basis for the prevention and control of foodborne diseases. MethodsAnal swabs or fecal samples from food-borne diarrhea cases were collected from two sentinel surveillance medical institutions in Baoshan District of Shanghai during 2019 and 2021. Salmonella, diarrheagenic Escherichia coli, Shigella, Vibrio parahaemolyticus, campylobacter and norovirus were tested in anal swabs and fecal samples, and all the testing results were statistically analyzed. ResultsA total of 1 693 cases were reported, among which 1 693 anal swabs and fecal samples were collected, with a male-to-female ratio of 1.04∶1. The largest number of cases was from the age group of 45-64 years (504 cases). The highest number of reported cases was among retirees (762 cases). The high-incidence period of the diseases was in summer and autumn, with the highest number of cases associated with meat and meat products (566 cases). The primary location of exposure was at home (1 260 cases). The detection rate of pathogenic bacteria and virus was 21.32%, among which campylobacter accounted for the largest proportion (10.28%). The peak incidence rate was from May to September. The detection rate of norovirus was 13.29%, with a higher incidence in winter and spring. The predominant serotype of Salmonella was Salmonella enteritidis (41.82%), and the predominant local serotype of diarrheagenic Escherichia coli was EAEC (50.52%). Campylobacter was mainly represented by jejuni (81.61%), and the predominant type of norovirus was GⅡ (60.87%). ConclusionCampylobacter has the highest proportion among foodborne pathogens causing foodborne diseases in Baoshan District, followed by diarrheogenic Escherichia coli. And norovirus GⅡ type is the predominant virus. Appropriate prevention and control measures should be taken based on the characteristics of each pathogen's epidemiology.

Chinese Journal of Plastic Surgery 2023;39(9):1013-1019
Melanoma is the skin malignancy with high potential of metastasis, and its morbidity rate is increasing every year. Melanoma patients exhibit a significantly elevated tumor mutational burden, with a higher prevalence of neoantigenic epitopes, leading to widespread activation of immune cells. Consequently, melanoma demonstrates a favorable response rate to immunotherapy. In this study, the infiltration landscape of common immune cells and their function in the melanoma microenvironment were depicted and analyzed. This study contributes to a better understanding among clinical practitioners of the role of the immune system in the development and progression of melanoma, and provides valuable guidance for the development of novel immunotherapeutic agents.
