OBJECTIVE To evaluate the impact of sublingual immunotherapy(SLIT)on the balance of Treg/Th17 cells and related cytokines in preschool children aged 3-6 years with allergic rhinitis(AR).METHODS Seventy preschool children aged 3-6 years with AR were divided into the SLIT group and the medication group,and their clinical data were retrospectively analyzed.The medication group received symptomatic treatment alone,while the SLIT group received a combined treatment of SLIT and symptomatic medication,with a 3-year follow-up period.The Treg/Th17 cell balance,serum levels of TGF-β,IL-10,IL-17,IL-21,as well as the total nasal symptom score(TNSS),total medication score(TMS),and visual analog scale(VAS)scores were compared before and after treatment between the two groups.RESULTS After 3 years of treatment,both groups showed significant improvements(P<0.05)in the percentages of CD4+CD25+Foxp3+Treg and CD4+IL-17+Th17 cells among CD4+T cells,percentages of Treg and Th17 cells,serum levels of TGF-β,IL-10,IL-17,IL-21,TNSS,TMS,and VAS scores.Moreover,the SLIT group exhibited significantly better outcomes compared to the medication group(P<0.05).CONCLUSION SLIT can modulate the balance of Treg/Th17 cells and improve serum levels of TGF-β,IL-10,IL-17,and IL-21.

Objective:To explore the epidemiological characteristics and spatiotemporal clustering of foodborne infection of Vibrio ( V.) parahaemolyticus in Ningbo, Zhejiang Province, from 2014 to 2022, and provide reference and evidence for the prevention and control of related diseases. Methods:The incidence data on of foodborne infection of V. parahaemolyticus in Ningbo from 2014 to 2022 were collected from Ningbo Foodborne Disease Surveillance System, and the case counts and the positive rates in different districts (counties, cities) were calculated. Spatial autocorrelation analysis and spatiotemporal scanning analysis were conducted to analyze the spatiotemporal clustering of the diseases. Results:A total of 1 822 cases of foodborne infection of V. parahaemolyticus were reported in Ningbo from 2014 to 2022, with an overall positive rate of 3.78%. Spatial autocorrelation analysis showed that the positive rate of foodborne infection of V. parahaemolyticus in Ningbo was unevenly distributed from 2014 to 2022, Ninghai was a high-high clustering area, while Zhenhai was a high-low clustering area, and Jiangbei was a low-low clustering area. The annual incidence was high during July-September. Spatiotemporal scanning analysis found one class Ⅰ spatiotemporal clustering area and three class Ⅱ spatiotemporal clustering areas, with the class Ⅰ spatiotemporal clustering area being observed in Jiangbei and Zhenhai from 2019 to 2022. Conclusions:Spatiotemporal clustering of foodborne infection of V. parahaemolyticus existed in Ningbo from 2014 to 2022, with an annual high incidence period from July to September. The key areas for the prevention and control of foodborne infection of V. parahaemolyticus are coastal districts (counties, cities) in Ningbo.

Objective:To analyze the distribution characteristics of special types of diabetes in China, in order to provide a theoretical basis for the diagnosis and treatment of special types of diabetes.Methods:Pubmed, CNKI, and WanFang Data were searched for the case reports and clinical studies of special types of diabetes in China from 2011 to 2021. After independent literature screening by 2 researchers according to the inclusion and exclusion criteria, diseases and the number of corresponding cases included were extracted for statistics. The etiological composition and disease characteristics of three subtypes of special type diabetes were analyzed.Results:A total of 613 articles(7 377 patients)were included and roughly divided into eight subtypes of special type diabetes according to etiological classification for disease composition analysis. The results by ratio in descending order were as follows: mono-genetic gene defects in islet β-cell function, pancreatogenic diabetes, diabetes induced by drugs or chemicals, endocrine disease, mono-genetic gene defects in insulin action, other genetic syndromes associated with diabetes, infection, and uncommon immune-mediated diabetes. The disease composition of the three subtypes of special types of diabetes that we focused on were mono-genetic gene defects in islet β-cell function(50.21%), pancreatogenic diabetes(35.65%), and mono-genetic gene defects in insulin action(1.56%). The composition analysis of the special types of diabetes in each subtype showed that neonatal diabetes mellitus(NDM, n=1 749, 23.71%)and maturity onset diabetes in young(MODY, n=1 554, 21.07%)accounted for the largest proportions. According to the composition analysis of each subtype of MODY patients, the top three subtypes were MODY2(50.89%), MODY3(16.03%), and MODYX(8.91%). In addition, taking MODY as an example, patients with de novo mutations(DNMs)and(or)new mutation sites were summarized and analyzed. The results revealed 31 MODY patients with DNMs(1.99%) and 339 MODY patients with new mutation sites(21.81%). Conclusions:According to the literature analysis, NDM and MODY represent the largest proportion of patients with special type diabetes in China. MODY2 patients make up the largest proportion of MODY patients. In addition, diabetic patients carrying DNMs and(or)new mutation sites should be taken seriously.

Objective: To analyze the epidemiological and pathogenic characteristics of foodborne diseases among students in Ningbo from 2014 to 2021, so as to provide a scientific basis for the prevention and control of foodborne diseases in schools. Methods: Information on foodborne disease cases among students attending all surveillance hospitals in Ningbo from 2014 to 2021 was collected from the Foodborne Disease Surveillance System of Zhejiang Province, and epidemiological characteristics and pathogenic analysis were analyzed. Results: A total of 3 602 cases of foodborne diseases in the student population were reported in Ningbo, of which 54.58% were males and 45.42% were females. Students aged 18 years and above accounted for the highest incidence group, and the incidence time mainly showed two peaks in May to June and September to October. Meat and meat products accounted for the largest proportion of suspicious foods (21.11%), and the positive pathogen detection rates were 11.20% for Norovirus, 3.30% for Vibrio parahaemolyticus, 1.77% for Salmonella, 1.30% for diarrheogenic Escherichia coli and 0.18% for Shigella. Conclusion The main suspect foods for foodborne diseases among students in Ningbo are primarily meat and meat products, and the main etiological agent is norovirus, which requires strengthening food safety health education and food safety management.

Objective: To investigate the lunch supply in primary and middle school dining rooms in Ningbo City, so as to provide the scientific evidence for guiding rational dietary supply and improving student health. Methods: A primary school and a junior high school were randomly sampled from each of 10 counties (districts) in Ningbo City. Food receipt and balance, dinner supply and number of students with meals were collected from school dining rooms with questionnaires formulated by Zhejiang Provincial Center for Disease Control and Prevention, and all foods in school dining rooms provided by enterprises were sorted and recorded. Daily mean lunch food, energy and nutrient supply was calculated per student, and evaluated with the Student Electronic Nutritionist platform, the 2013 revision of Chinese Dietary Reference Intakes and the national criteria of Nutrition Guidelines of Student Meals (WS/T 554-2017). Results: Six urban primary schools, six urban junior high schools, four rural primary schools and four rural junior high schools were enrolled, and there were two schools with meals provided by enterprises and eighteen schools with meals provided by their dining rooms. Appropriate supply of cereals and potatoes, excessive supply of livestock and poultry meat, vegetable oil and salt, and low supply of fruits, eggs, milk and soybean and nuts were found in primary and junior high school, and notably, milk and fruits were not provided by any rural junior high schools. Excessive energy supply was found in primary schools (excessive energy supply in rural primary schools and appropriate in urban primary schools), and appropriate energy supply was seen in junior high schools. High energy ratios of protein and fat, low energy ratio of carbohydrate, low supply of diatery fiber, vitamin A and calcium, appropriate supply of vitamin B1, B2 and C, and sufficient supply of iron and zinc were found in primary and junior high school. Conclusion Unreasonable dietary structure, excessive energy supply and nutrient imbalance are found in lunch supply by primary and junior high schools in Ningbo City.

Objective:To analyze the incidence and risk factors of non-acute symptomatic portal vein thrombosis (PVT) after endoscopic gastric variceal injection (GVI) in the treatment of liver cirrhosis with gastric variceal bleeding (GVB).Methods:66 patients with GVB who were treated with GVI for the first time from July 2017 to October 2019 in Minhang Hospital Affiliated to Fudan University were retrospectively analyzed. The data of gender, age, preoperative Child-Pugh grade, preoperative platelet count, preoperative plasma D-dimer concentration, preoperative splenic length, preoperative portal vein velocity, preoperative splenic vein velocity, preoperative portal vein diameter, preoperative splenic vein diameter, treatment times, total number of injection points, total dose of sclerosing agent and tissue adhesive agent were collected. The patients were divided into PVT group and non-PVT group according to the occurrence of non-acute symptomatic PVT within one year after GVI. Univariate analysis was performed first, and then the factors with P<0.2 were included in the binary logistic regression model to screen the risk factors of PVT after GVI. Results:There were 25 cases (37.88%) in PVT group and 41 cases (62.12%) in non-PVT group. There were significant differences in D-dimer concentration, spleen length, Child-Pugh grade and total dose of sclerosing agent between the two groups ( P<0.05). The D-dimer concentration ( OR=2.319, 95% CI:1.359-3.956), spleen length ( OR=1.044, 95% CI:1.007-1.081) and total dose of sclerosing agent ( OR=1.075, 95% CI:1.004-1.152) were independent risk factors for PVT ( P<0.05). Conclusions:Preoperative D-dimer concentration, spleen length and total dose of sclerosing agent can predict the risk of PVT after GVI. In order to reduce the risk of PVT after GVI, the dose of sclerosing agent should be reduced as much as possible.

Objective:The particularity of drugs determines the particularity of drug patents. From the legal perspective, this means that special terms should be included designed in the patent law system.The interests of patent holders are not fully protected currently, although some drug related provisions have been set in the current patent law. Along with the many reforms that China has implemented in the field of new drug research and development, there are some problems related to drugs that need to be resolved in the patent system, This article will explore this issue.Methods:Based on the particularity of drug patents, this paper analyzes the necessity of improving the relevant provisions of the patent law for the research and development of new drugs, and proposes suggestions for improving the terms of drug patents.Results:There is still space for improvement in terms of balancing the interests of the innovator, the generic maker and the public.Conclusions:The necessary improvements and adjustments to the drug provisions in the patent laws and regulations need to be made in order to further enhance the patent system’s role in promoting the research and development of new drugs.

Objective The aim of the study was to explore the influencing factors of exercise tolerance in patients with myocardial infarction (MI) after percutaneous coronary intervention (PCI) revascularization in acute state. Methods A total of 112 patients with first MI undergoing PCI revascularization in acute state and completing cardiopulmonary exercise testing (CPET) were enrolled. Exercise capacity was evaluated by peak oxygen consumption percentage (VO2 peak%) in CPET. Patients were divided into normal exercise capacity (NEC) group (n=40) and abnormal (AEC) group (n=72) according to VO2 peak% value. Clinical manifestations, histories of hypertension and diabetes, medications, coronary arterial angiography and echocardiography findings of patients were compared. The onsets of diabetes and blood glucose levels during the period of CPET were evaluated in the MI patients with diabetes. The patients were followed up for major adverse cardiovascular events (MACE) (admission due to chest pain, re?revascularization, re?infarction and all?cause death) within 24 months after PCI. Multivariate logistic regression analyses were conducted to examine influencing factors for exercise tolerance. Results The ratio of diabetes, type C lesions in the AEC group were higher than those in the NEC group (diabetes: 37.5% vs. 17.5%; type C lesions: 69.4% vs. 42.5%, respectively, all P<0.05). The left ventricular ejection fraction (LVEF) in patients in the AEC group was lower than that in the NEC group [(60.6±10.0) % vs. (65.0±8.2) %, P=0.019]. Multivariate logistic regression analyses showed that history of diabetes and history of type C lesions were the independent risk factors for the declined exercise capacity in the MI patients after PCI revascularization ( OR=3.14, 95%CI 1.167-8.362, P=0.023; OR=3.32, 95%CI 1.444-7.621, P<0.01). Among the MI patients with diabetes, the duration of diabetes in the AEC group was significantly longer than that in the NEC group[ (7.7 ± 3.6)years vs. (5.0 ± 2.4)years] and the proportions of subjects reaching target levels of fasting plasma glucose (40.7% vs. 57.1%) and glycosylated hemoglobin A1c(HbA1c) (55.6% vs. 71.4%) in this group were significantly lower than those in the NEC group (all P<0.05). A multivariate logistic regression analysis showed that reaching HbA1c target was an independent predictor of improved exercise tolerance in MI patients with diabetes who received PCI ( OR=2.518, 95%CI 1.395-7.022, P=0.021). No significant differences were observed in incidence of admission due to chest pain, re?revascularization and re?infarction between the two groups within 24 months after PCI between the groups. Conclusions Diabetes and type C lesions are independent risk factors of declined exercise capacity in patients with first myocardial infarction who received revascularization in acute state. Reaching target HbA1c is independent factor of improved exercise capacity in patients with myocardial infarction and diabetes.
