Methods:A total of 392 patients with seasonal allergic rhinitis were selected from the population of the epidemiological investigation project of allergic diseases in Hohhot, Inner Mongolia. The project was led by Department of Allergy, Beijing Shijitan Hospital, Capital Medical University, and assisted by Hohhot First Hospital from April to May 2023. The patients were randomly divided into a spleen aminopeptide group (296 cases) and control group (96 cases) at a ratio of 3∶1, and the enrollment period was from June 1 to 14, 2023. The treatment group was treated with spleen aminopeptide oral solution for 12 weeks starting from 4-6 weeks (±7 days) before the pollen dispersal period, while the control group was treated with a simulated agent of spleen aminopeptide oral solution. Both the treatment group and the control group were treated with oral antihistamines and/or nasal glucocorticoids as needed during the pollen dispersal period. Evaluate the therapeutic effect by comparing the symptom scores, drug scores and quality of life scores of the two groups, and detect the expression levels of cytokines in serum. Symptom scores, quality of life scores, drug scores and laboratory results were compared by independent sample t test/Kruskal-Wallis test and χ2 test/Fisher′s exact test. Results:Compared with the control group, spleen aminopeptide treatment for 12 weeks significantly improved symptoms of nasal congestion [ M( Q1, Q3):2(1, 2) vs. 2(1, 3), H=6.308, P<0.05], nasal itching [ M( Q1, Q3):2(1, 2) vs. 2(1, 3), H=4.966, P<0.05], sneezing [ M( Q1, Q3):2(1, 2) vs. 2(1, 3), H=5.245, P<0.05], runny nose [ M( Q1, Q3):2(1, 2) vs. 2(1, 3), H=5.41, P<0.05] and tearing [ M( Q1, Q3):1(0, 2) vs. 1(0, 3), H=4.664, P<0.05]. At 12 weeks of treatment, the scores of nasal symptoms and ocular symptoms in control group and experimental group were significantly increased compared with baseline ( P<0.05). In experimental group, nasal congestion [ M( Q1, Q3):1(0, 1) vs. 1(0, 2), H=4.042, P<0.05], eye itching/foreign body sensation/redness symptom scores [ M( Q1, Q3):1(0, 2) vs. 1(0, 2), H=5.302, P<0.05] and total scores [ M( Q1, Q3):4(-1, 9) vs. 5(0, 12.5), H=3.958, P<0.05] were significantly increased. The antihistamine drug score of the splenic peptide treatment group at 6 weeks were lower than that of the control group ( H=4.232, P<0.05). After 12 weeks of treatment, the antihistamine drug score [ M( Q1, Q3):10(0, 24) vs. 19(2, 36.5), H=6.67, P<0.05] and the total drug score [ M( Q1, Q3):28.5(5, 77.5) vs. 46(6, 155.5), H=3.995, P<0.05] were significantly lower than those of the control group. The serum IL-17A levels of the treatment group were significantly lower than those of the control group after 6 weeks (0.7±1.77 vs. 0.85±1.67 ,H=10.08, P<0.05) and 12 weeks (0.81±1.63 vs. 0.94±1.73, H=5.196, P<0.05) of splenic aminopeptide treatment. Conclusions:Early treatment with spleen aminopeptide oral solution can significantly improve nasal and ocular symptoms of patients with seasonal allergic rhinitis, reduce the use of drugs during the onset period, and improve the quality of life. It may exert an immunomodulatory effect by reducing the expression level of IL-17A in the serum of patients.Objects:To conduct a study on the prevention and treatment of seasonal allergic rhinitis in Hohhot, Inner Mongolia, evaluate the preventive and therapeutic effects of spleen aminopeptide oral solution on seasonal allergic rhinitis, and explore its related mechanisms.

Objective To investigate the effect of Cyclocarya paliurus(Batal.)lljinskaja polysaccharides on insulin resistance in type 2 diabetic rats by regulating glucose transporter 4(GLUT4)translocation in islet and liver.Methods High-fat diet combined with low-dose streptozotocin(35 mg·kg-1)to induce type 2 diabetes model,all the rats were randomly divided into model control group,Cyclocarya paliurus polysaccharides groups(5,10 g·kg-1)and metformin group(0.25 g·kg-1),and treated for eight weeks(n=9 in each group).Fasting glucose and lipid were determined.Histopathology of rat islet and liver were observed by hematoxylin and eosin staining.Protein expressions of phosphorylated phosphoinositide-3-kinase(p-PI3K),phosphorylated serine-threonine kinase 1(p-Akt1),and GLUT4 in islet were measured by immunohistochemistry staining.GLUT4 translocation in the islet and liver was detected by immunofluorescence.Results Compared with the model control group,the Cyclocarya paliurus polysaccharides group and metformin group had declined fasting glucose levels and increased high-density lipoprotein(P＜0.05).The structure of the islets and liver was relatively complete.The content of p-PI3K,p-Akt1 and GLUT4 in the islet increased(P＜0.05).GLUT4 translocation in the liver and islet enhanced(P＜0.05).Conclusions Cyclocarya paliurus polysaccharides alleviate glucose and lipid metabolism disorders.The mechanism may lay in it activating protein expressions of p-PI3K,p-Akt1,and GLUT4 in islet cells.GLUT4 translocation to the islet and liver cell membrane are increased to regulate peripheral islet resistance.

Objective:To investigate the independent predictors for malignancy in colorectal laterally spreading tumors (LSTs) by therapeutic endoscopy.Methods:Data of consecutive patients with colorectal LSTs who underwent endoscopic treatment in Beijing Friendship Hospital between June 2013 and March 2019 were collected for retrospective analysis. Patients′ gender, age, body mass index, smoking history, and endoscopic and histological results were reviewed. Univariate analysis was used to identify the associated factors for malignancy of colorectal LSTs. Factors with statistical significance in univariate analysis were used in multivariate logistic regression to determine the independent predictors.Results:A total of 323 patients with 341 colorectal LSTs were involved in the study. The rate of malignancy was highest in non-granular pseudo depressed (NG-PD) subtype [85.48% (53/62)], followed by granular nodular mixed (G-NM) subtype [76.97% (117/152)]. Both of the above rates were significantly higher than that of granular homogenous (G-H) subtype [29.51% (18/61), P<0.001] and non-granular flat elevated (NG-FE) subtype [24.24% (16/66), P<0.001]. Univariate analysis showed that NG-PD subtype ( P<0.001, OR=18.40, 95% CI: 7.46-45.42), G-NM subtype ( P<0.001, OR=10.45, 95% CI: 5.30-20.58), rectosigmoid location ( P<0.001, OR=2.33, 95% CI: 1.47-3.69) and size ≥2 cm ( P<0.001, OR=2.60, 95% CI: 1.60-4.00) associated with malignancy for colorectal LSTs. In multivariate logistic regression, NG-PD subtype ( P<0.001, OR=17.51, 95% CI: 7.06-43.43), G-NM subtype ( P<0.001, OR=8.25, 95% CI: 4.07-16.73) and size ≥2 cm ( P=0.032, OR=1.80, 95% CI: 1.05-3.08) remained to be independent predictors. Conclusion:LSTs of NG-PD subtype, G-NM subtype or size ≥2 cm are high risk factors of malignancy, in which cases, en bloc resection is required.

Objective:To investigate the risk factors for prolonged procedure time of endoscopic submucosal dissection (ESD) for colorectal laterally spreading tumors (LSTs).Methods:Consecutive patients who underwent ESD for colorectal LSTs at Beijing Digestive Disease Center from June 2013 to March 2019 were retrospectively analyzed. Univariate analysis was used to identify factors associated with prolonged procedure time (≥60 min). Factors with significant difference in univariate analysis were included in multivariate logistic regression to determine the independent risk factors.Results:A total of 201 patients (age 65.05±10.44 years old, 53.73% were males) with 213 LSTs (diameter 2.52±1.67 cm) were included. En bloc resection rate, complete resection rate and curative resection rate were 93.90%, 84.04% and 79.81%, respectively. Intraoperative perforation rate, delayed perforation rate and delayed bleeding rate were 1.88%, 0.94% and 1.41%, respectively. Diameter ≥3 cm ( OR=13.48, P<0.001), granular nodular mixed (G-NM) subtype ( OR=25.28, P=0.002), granular homogenous subtype ( OR=9.00, P=0.045), location of rectosigmoid ( OR=3.08, P=0.002) and positive non-lifting sign ( OR=3.40, P=0.012) were associated with longer procedure time in univariate analysis. In multivariate logistic regression, diameter ≥3 cm ( OR=9.29, P<0.001), G-NM subtype ( OR=8.80, P=0.043) and positive non-lifting sign ( OR=3.43, P=0.043) were independent risk factors for prolonged procedure time. Longer procedure time was associated with lower rates of complete resection (69.56% VS 88.55%, P=0.003) and curative resection (63.64% VS 85.50%, P=0.002), and increased rate of carcinoma (86.96% VS 51.91%, P<0.001). Conclusion:LSTs of size over 3 cm, G-NM subtype or positive non-lifting sign predict prolonged procedure time, which is associated with reduced efficacy of ESD and higher risk of carcinoma.

Objective: To investigate the self-reported prevalence, clinical characteristics, complications of allergic rhinitis (AR) and the sensitization of outdoor air pollen allergens in children in the Inner mongolia grassland region. Methods: A multistage, stratified and random clustered sampling with a face-to-face interview survey study in children from 0 to 17 years old was performed together with 10 common allergen skin prick tests (SPT) and measurements of the daily pollen count in 6 regions in the Inner mongolia grassland region from May to August of 2015. SAS 9.4 software was used for data analysis. Results: A total of 2 443 subjects completed the study. The self-reported prevalence of AR was 26.6%. The prevalence of boys was higher than that of girls (28.8% vs 24.3%, χ²=6.157, P<0.05). Subjects from urban areas showed higher prevalence than rural areas (34.7% vs 18.8%, χ²=79.107, P<0.05). There was significant regional difference in the prevalence of AR among the six areas investigated (χ²=221.416, P<0.05). The main clinical symptoms of AR were sneezing (88.2%) and nasal congestion (78.6%). Among combined diseases, asthma accounted for 16.5% (107/650), rhinoconjunctivitis accounted for 47.9% (311/650). The peak season of AR was April and July, with the top SPT positive allergens of Artemisia species and chenopodium in this area. Conclusions The prevalence AR in children in the Inner mongolia grassland region is extremely high. Sneezing is the main clinical symptom. Rhinoconjunctivitis is the most common combined disease. High summer and autumn pollen exposure is the main cause of AR.

Objective To evaluate the efficacy and safety of 1 940 nm thulium laser on peroral endoscopic myotomy (POEM) for treatment of patients with achalasia of cardia. Methods Fifteen patients undergoing POEM in Beijing Friendship Hospital from February 2016 to November 2016 were enrolled and divided into 1 940 nm thulium laser group ( n＝7) and high frequency electric knife group ( n＝8) using zelen′s design, with followed-up for three months. The operation time, success rate, efficacy, and complications were compared between the two groups. Results All the procedures were successfully completed. There was no significant difference on baseline between the two groups ( P＞0. 05). The time of total operation, creating submucosal tunnel, myotomy, and closing incision were not significantly different between the two groups (all P＞0. 05). The bleeding amount, creating tunnel bleeding amount, and myotomy bleeding amount were not significantly different between the two groups (all P＞0. 05). The complication rate during operation and one week after operation was not significantly different between the two groups ( P＝0. 76).The time of creating mucosal incision for the 1 940 nm thulium laser group was longer than that of the high frequency electric knife group ( 3. 7 ± 3. 0 min VS 2. 3 ± 1. 3 min, P＝ 0. 02). After one month of follow-up, the efficiency of the 1 940 nm thulium laser group and the high frequency electric knife group was 100. 0%(7/7) and 87. 5%(7/8), respectively (P＝0. 33), and the complication rate was 14. 3%(1/7) and 12. 5%(1/8), respectively (P＝0. 92). After three months of follow-up, the efficiency of the two groups was 100. 0%(7/7) and 75. 0%( 6/8), respectively ( P＝0. 16), and the complication rate was 28. 6%(2/7) and 12. 5%(1/8), respectively (P＝0. 60). Conclusion 1 940 nm thulium laser and high frequency electric knife both have good utility on POEM.1 940 nm thulium laser decreases the operating time and bleeding compared with high frequency electric knife.

Objective To observe the clinical curative effects of Changwei Shu combined with conventional western medicine therapy in treating the sepsis patients with gastrointestinal dysfunction.Methods A total of 120 cases of sepsis patients with gastrointestinal dysfunction were randomly divided into treatment group and control group,60 patients in each group.The control group was given conventional western medicine therapy,and the treatment group was given Changwei Shu combined with conventional western medicine therapy.After treatment for 7 days,the clinical efficacy and safety were evaluated by observing the changes in white blood cell (WBC) count,procalcitonin (PCT) level,intra-abdominal pressure (IAP),gastrointestinal dysfunction scores,and scores of acute physiology and chronic health evaluation (APACHE Ⅱ).Results (1) For one case dropped out and one was excluded from the treatment group,and 4 cases dropped out and 2 were excluded from the control group,a total of 58 cases in the treatment group and 54 in the control group were included into the study at the end of the trial.(2) The total effective rate of the treatment group was 91.38％ and that of the control group was 88.89％,the difference being significant (P ＜ 0.05).(3) After treatment,WBC count,PCT level and IAP of the two groups were improved (P ＜ 0.01 compared with those before treatment),and the improvement of the treatment group was superior to that of the control group (P ＜ 0.01).(4) After treatment,gastrointestinal dysfunction scores and APACHE Ⅱ scores of the two groups were decreased(P ＜ 0.01 compared with those before treatment),and the decrease of the treatment group was superior to that of the control group (P ＜ 0.01).(5) During the treatment,4 cases from the treatment group had nausea,and 5 cases from the control group had nausea and abdominal distention,and the symptoms disappeared spontaneously one week later.No obvious changes were found in the hepatic and renal function of the two groups.Conclusion Changwei Shu exerts an effect on reducing the inflammation,improving the gastrointestinal function,and relieving the illness severity of sepsis patients with gastrointestinal dysfunction.

Objective To investigate the influencing factors for non/low-response to hepatitis B vaccine in infants of HBsAg-positive mothers.Methods A total of 286 HBsAg-positive pregnant women and their infants were recruited from the Third People's Hospital of Taiyuan during July 2011 to January 2013.The infants were immunized with hepatitis B vaccine according to the 0-1-6 month vaccination schedule and followed up for 12 months.The serum HBV DNA level of mothers,neonates and infants were detected by electro chemilum inescence immunoassay kits and fluorescene quantiative polymerase chain rection.Results Among 286 infants,the rate of non/low-response to hepatitis B vaccine was 18.53％ (53/286).Non-conditional logistic regression analysis indicated that the mother's HBV DNA level ≥ 1 × 107 copies/ml (0R=2.592,95％CI:1.121-5.996) and natural birth (OR=1.932,95％CI:1.021-3.654) were the risk factors for non/low-response to hepatitis B vaccine,the risks were 2.592 times and 1.932 times higher compared with the infants whose mothers were HBV DNA negative and the infants whose mothers had cesarean delivery.There was no multiplicative or additive interaction between high HBV DNA load and natural birth (OR=1.055,95％CI:0.209-5.321),(RERI=1.617,95％CI:-4.038-7.272;AP=0.364,95％CI:-).527-1.225;SI=1.195,95％CI:0.270-13.135).After stratified analysis of mother's HBV DNA level,delivery mode of mothers was not associated with non/low-response of their infants.Conclusion The mother's load of HBV DNA ≥ 1 × 107 copies/ml might be the factor for non/low-response to hepatitis B vaccine in infants of HBsAg positive mothers.
