OBJECTIVE: To explore the efficacy of acupuncture based on "gut-brain axis" combined with sensory integration training in children with autism spectrum disorder (autism) and its effect on gastrointestinal symptoms. METHODS: A total of 96 children with autism were randomized into an observation group and a control group, 48 cases in each group, with 3 cases dropped out. Children in the control group received sensory integration training. On the basis of the treatment in the control group, children in the observation group received acupuncture therapy based on "gut-brain axis", and the point selection of scalp acupuncture was forehead five needles, i.e. bilateral Touwei (ST8), Toulinqi (GB15), Shenting (GV24) and Sishencong (EX-HN1), the point selection of body acupuncture was Zhongshu (GV7) and bilateral Tianshu (ST25), Pishu (BL20), Xinshu (BL15), Zusanli (ST36), Hegu (LI4), Taichong (LR3). Acupuncture was delivered once every other day, 3 times a week. Both groups were treated for 12 weeks. Before and after treatment, the scores of autism behavior checklist (ABC), childhood autism rating scale (CARS), autism treatment evaluation checklist (ATEC) and gastrointestinal TCM symptoms, as well as the relative abundance of intestinal flora were compared, and the clinical efficacy was evaluated in the two groups. RESULTS: After treatment, the ABC and CARS scores were decreased compared with those before treatment in the two groups (P<0.001, P<0.05), and the ABC and CARS scores in the observation group were lower than those in the control group (P<0.01). After treatment, the item scores of language, sensory perception, sociability, behavior, and the total score of ATEC in the observation group were decreased compared with those before treatment (P<0.001, P<0.01), the item scores of language, sociability, behavior, and the total score of ATEC in the control group were decreased compared with those before treatment (P<0.01, P<0.001, P<0.05); the each-item and total scores in the observation group were lower than those in the control group (P<0.05). After treatment, the scores of loose stool, stomach duct pain, stomach duct stuffiness, decreased appetite, and the total scores of gastrointestinal TCM symptoms were reduced compared with those before treatment in the two groups (P<0.001), and the above scores in the observation group were lower than those in the control group (P<0.001). After treatment, the relative abundance of Escherichia coli and Enterococcus was decreased compared with that before treatment in the two groups (P<0.001), and the above relative abundance in the observation group was lower than that in the control group (P<0.001); the relative abundance of Bifidobacterium and Lactobacillus was increased compared with that before treatment in the two groups (P<0.001), and the above relative abundance in the observation group was higher than that in the control group (P<0.001). The total effective rate was 88.9% (40/45) in the observation group, which was higher than 66.7% (30/45) in the control group (P<0.05). CONCLUSION On the basis of sensory integration training, acupuncture based on "gut-brain axis" can improve the behavioral status and gastrointestinal symptoms, and correct the imbalance of intestinal flora in children with autism.

Objective To analyze the dynamic changes and influencing factors of Mycobacterium tuberculosis(TB)infection in grade-1 students in senior high school at the time of enrollment and one year after enrollment.Methods In 2022,TB screening was carried out among grade-2 students in 4 senior high schools in Binhai and Xiqing Districts of Tianjin.Basic information of students was collected,and TB infection detection results of grade-1 students in senior high school at the time of enrollment were collected retrospectively.Positive rate,strong positive rate and positive conversion rate from tuberculin skin test(TST)results of students were compared.Univariate and multiva-riate logistic regression models were used to analyze the relevant influencing factors for positive conversion of TST results.Results The overall positive rate of 1 839 students one year after enrollment was higher than that at the enrollment(46.82％vs 33.12％),while strong positive rate was lower(12.51％vs 13.00％),both with statisti-cally significant differences(both P＜0.001).One year after enrollment,64 out of 1 230 students who were origi-nally negative for TST in their first year of senior high school turned positive,with a positive conversion rate of 5.20％(95％CI:3.93％-6.48％).One year after enrollment,TST results showed that the average diameter of induration was 5(2,8)mm,diameter was 2(0,5)mm at the enrollment of the first year of senior high school,but the difference was not statistically significant(P=0.478).The difference range of average diameter of induration was±21 mm,39.70％of students being within±2 mm.Students with increased and decreased average diameter of induration accounted for 65.09％and 28.49％,respectively.Multivariate logistic regression analysis result showed that students in boarding school had a higher risk of positive conversion compared with non-boarding school students(OR=4.842,95％CI:2.794-8.392).Conclusion The screening of TB infection among grade-2 students in senior high school should be strengthened,with a focus on boarding school students.Early detection of tuberculosis patients and newly infected individuals can provide reference for implementing precise prevention and control.

Objective To observe the effectiveness and safety of pirfenidone in the prevention and treatment of radiation-induced lung injury in esophageal cancer.Methods We retrospectively analyzed the data of 103 patients with esophageal cancer,of whom 53 in the combined group were treated with simultaneous chemoradiotherapy combined with pirfenidone and 50 in the control group were treated with simultaneous chemoradiotherapy only.The patients were followed up for three years to observe the treatment effects,adverse effects,and survival,as well as the incidence of radiation-induced lung injury,lung function,and changes in lung injury cytokine levels within one year after radiotherapy.Results Treatment efficiency in the combined group was higher than that in the control group(86.8%vs.70.0%,P＜0.05).The two-and three-year survival rates in the combined group were 84.9%and 71.7%,respectively,which were higher than those(68.0%and 52.0%)in the control group(P＜0.05).The one-,two-,and three-year disease-free survival rates in the combined group were 86.8%,67.9%,and 47.2%,respectively,which were higher than those(62.0%,46.0%,and 28.0%)in the control group(P＜0.05).The incidence rates of radiation pneumonitis at three months,pulmonary fibrosis at six months,and one year after radiotherapy in the combined group were 22.6%,13.2%,and 14.0%,respectively,which were lower than those(42.0%,30.0%,and 31.8%)in the control group at the same time(P＜0.05).At the end of radiotherapy and at three months,six months and one year after radiotherapy,the combined group showed higher levels of lung function indicators but lower levels of lung injury-related cytokines than the control group(P＜0.05).The incidence of rash in the combined group was 18.9%,which was higher than that(2.0%)in the control group(P＜0.05).However,no statistically significant difference in the incidence and severity of other adverse reactions was found between the two groups(P＞0.05).Conclusion Pirfenidone not only effectively reduces radiation-induced lung injury and improves lung function in esophageal cancer patients undergoing simultaneous chemoradiotherapy,but also helps improve tumor control rates and patient survival with a good safety profile.

Objective:To analyze the fail mode of neoadjuvant therapy combined with surgery for locally advanced esophageal squamous cell carcinoma (ESCC) after long-term follow-up.Methods:Clinical data of consecutive 238 patients with locally advanced resectable ESCC who underwent neoadjuvant therapy combined with surgery in Zhejiang Cancer Hospital from September 2012 to October 2019 were retrospectively analyzed. The failure mode in the whole cohort was analyzed after long-term follow-up. The overall survival (OS) and disease free survival (DFS) rates were analyzed by Kaplan-Meier method. Survival differences were determined by log-rank test.Results:The pathological complete response (pCR) rate was 42.0% in 238 patients. After a median follow-up of 46.1 months, tumor progression occurred in 96 patients (40.3%), including 25 patients (10.5%) with local recurrence, 61 patients (25.6%) with distant metastases, and 10 patients (4.2%) with simultaneous local recurrence and distant metastases. The median OS and DFS were 64.7 months and 49.9 months. And the 3-, 5-, and 7-year OS and DFS rates were 70.0%, 52.8%, 36.4% and 63.5%, 42.5%, and 30.0%, respectively. The 3-, 5-, and 7-year locoregional recurrence-free survival rates and distant metastasis-free survival rates were 86.0%, 71.4%, 61.2% and 70.6%, 55.9%, 43.0%. Compared with non-pCR patients, the overall progression rate and distant metastasis rate of pCR patients were lower (26.0% vs. 50.7%, 16.0% vs. 32.6%, both P<0.05). And the 3-, 5-, and 7-year OS (83.0% vs. 60.2%, 69.7% vs. 41.7%, 50.4% vs. 27.7%, all P<0.001) and DFS rates (80.4% vs. 51.4%, 63.9% vs. 31.2%, 45.9% vs. 20.3%, all P<0.001) were significantly better in pCR patients. Conclusions:Distant metastasis is the main failure mode of patients with locally advanced ESCC after neoadjuvant therapy. Patients with postoperative pCR can achieve better long-term survival.

Objective: To analyze the level and trend of microbial contamination in food in rural compulsory education schools in Baiyin City, so as to provide a reference for playing an early warning role in eliminating potential food safety hazards as soon as possible. Methods: According to the "National Food Contaminants and Harmful Factors Risk Monitoring Workbook", etc., 8 pathogenic bacteria such as Salmonella, Listeria monocytogenes, Staphylococcus aureus, total bacterial count, and 2 hygienic indicator bacteria of coliform were tested. Results: A total of 908 food samples were collected from 2013 to 2021, 47 were positive and the overall positive rate was 5.18%. The positive rate of samples collected in different years showed a downward trend year by year. The detected pathogenic bacteria ranked from high to low as follows: Escherichia coli (1.87%), Bacillus cereus (0.99%), Staphylococcus aureus (0.44%), mold (0.33%), Listeria monocytogenes (0.22%). Hygiene indicator bacteria total number of bacteria exceeded the standard rate was higher (2.09%). Among all kinds of food, milk and dairy products, frozen food, cold food, barbecue, rice and flour products had higher positive rates. According to quarterly statistics, the positive rate in the first and second quarters was relatively high. Conclusion There are different degrees of microbial contamination risks in the food of rural compulsory education schools. All relevant departments should pay attention to the current situation of school food hygiene and safety in poverty stricken areas, and strengthen rural compulsory education school food, especially for milk and dairy products, frozen food, cold food, Supervision of key foods such as barbecue, rice and flour products, and efforts to improve their safety standards, do a good job in school food hygiene and safety, and ensure the healthy growth of young people.

Background: Esophageal mucosal injury induced by gastroesophageal reflux is a key link to the development of Barrett's esophagus-associated adenocarcinoma. However, the molecular mechanism is still not elucidated. Aims: To investigate the role of differentially expressed genes (DEGs) after stimulating esophageal cells with acid and bile acid in the development of esophageal adenocarcinoma (EAC). Methods: The DEGs were obtained through bioinformatics methods after stimulating esophageal cells with low pH and deoxycholic acid, and GO, KEGG enrichment analysis were performed. Protein-protein interaction (PPI) network was performed to screen the hub genes, and their relationships with prognosis and tumor stage of EAC patients were analyzed. The role of co-expressed genes of GADD45B in EAC was also analyzed. Results: Thirty-one overlapping DEGs were obtained after stimulating esophageal cells with low pH and deoxycholic acid, which mainly enriched in the cytokine-cytokine receptor interaction, transcription factors activity, and regulation of cell proliferation and apoptotic process. High expression of GADD45B was correlated with the survival prognosis and tumor stage of EAC patients. GADD45B and its co-expressed genes were involved in the production of tumor necrosis factor. Conclusions: The high expression of GADD45B induced by acid and bile acid is correlated with the prognosis and tumor stage of EAC patients, and is a potential diagnosis and treatment target for Barrett's esophagus-associated adenocarcinoma.

Objective To investigate and analyze the reasons for the omission of adjuvant radiotherapy after breast-conserving surgery (BCS) in patients with breast cancer.Methods The clinicopathologial characteristics and socioeconomic data of 55 breast cancer patients undergoing BCS without postoperative adjuvant radiotherapy in our hospital from 2012 to 2016 were retrospectively analyzed.Results Among the 55 patients who did not receive radiotherapy,25 patients were due to low local recurrence risk,12 patients were due to economic or family reasons,12 patients were due to fear of adverse reactions of radiotherapy,and 5 patients were not recommended by primary physicians for radiotherapy.In addition,3 cases with multiple distant metastases and 3 cases with concomitant thyroid cancer didn't received radiotherapy.Conclnsions Low risk local recurrence is the main reason for the omission of adjuvant radiotherapy,followed by the fear of radiation-induced toxicity and poor financial support.Patient education and medical insurance may improve the adjuvant radiotherapy compliance.

Objective: To analyze the distribution of the regulator of G protein signaling 2 (RGS2) gene C1114G polymorphism in children with vasovagal syncope (VVS) and the associated clinical classification groups, and to explore the association between RGS2 C1114G and VVS. Methods: This was a prospective case-control study. A head-up tilt test (HUT) was performed in 300 children visiting Children's Hospital Affiliated to Shanghai Jiaotong University from August 2010 to December 2015 for unexplained syncope. A total of 150 children with positive HUT and a diagnosis of VVS were enrolled and assigned to the VVS group. The VVS group was further divided into 3 subgroups based on characteristics of the heart rate and blood pressure measured during the HUT. A total of 150 children with negative HUT were enrolled and assigned to the HUT-negative group. A total of 150 healthy children were enrolled as the normal control group for genetic polymorphism detection. The clinical characteristics of patients in the VVS group and the HUT-negative group were recorded. Peripheral blood samples of each case were collected. RGS2 C1114G polymorphism was evaluated using high-resolution melting curve and polymerase chain reaction together with gene sequencing. The genotype and allele frequency were analyzed and compared among different groups (VVS, HUT-negative, and normal control) and VVS subgroups. Comparisons among groups were performed using Chi-square test. Results: Patients in the VVS group (48 males and 102 females, aged (10.1±3.2) years) were more frequently female (68.0% vs. 57.3%;χ²=5.090, P=0.024) compared with patients in the HUT-negative group (67 males and 83 females, aged (10.8±2.2) years). No significant difference was found regarding the distribution of the CC genotype, CG genotype and GG genotype among the VVS group (n=98, 65.3%; n=36, 24.0%; n=16, 10.7%), the HUT-negative group (n=112, 74.7%; n=28, 18.7%; n=10, 6.7%) and the normal control group (n=108, 72.0%; n=31, 20.7%; n=11, 7.3%) (χ²=3.632, P=0.458). There was no significant difference in the frequencies of C allele and G allele in the VVS group (n=232, 77.3%; n=68, 22.7%), the HUT-negative group (n=252, 84.0%; n=48,16.0%) and the normal control group (n=247, 82.3%; n=53, 17.7%) (χ²=4.659, P=0.097). The 150 children in the VVS group were further divided into the mixed-response subgroup (n=83), vasodepressor-response subgroup (n=42) and cardioinhibitory-response subgroup (n=25). The CC genotype, CG genotype and GG genotype in the mixed-response subgroup, the vasodepressor-response subgroup and the cardioinhibitory-response subgroup were (n=65, 78.3%; n=16, 19.3%; n=2, 2.4%), (n=20, 47.6%; n=11, 26.2%; n=11, 26.2%) and (n=13, 52.0%; n=9, 36.0%; n=3, 12.0%), respectively. The frequencies of C allele and G allele in the mixed-response subgroup, the vasodepressor-response subgroup, and the cardioinhibitory-response subgroup were (n=146, 88.0%; n=20, 12.0%), (n=51, 60.7%; n=33, 39.3%) and (n=35, 70.0%; n=15, 30.0%), respectively. The percentages of the GG genotype and G allele were significantly higher in the vasodepressor-response subgroup than the other two subgroups (χ²=21.698, 25.345, all P=0.000). Conclusions No significant association was found between RGS2 C1114G polymorphism and VVS in children. Due to the higher distribution of GG genotype and G allele in the vasopressor-response subgroup, RGS2 C1114G may be associated with the regulation of blood pressure during the onset of VVS in children.
