RESUMO
OBJECTIVES@#To study the efficacy and safety of Xiyanping injection through intramuscular injection for the treatment of acute bronchitis in children.@*METHODS@#A prospective study was conducted from December 2021 to October 2022, including 78 children with acute bronchitis from three hospitals using a multicenter, randomized, parallel-controlled design. The participants were divided into a test group (conventional treatment plus Xiyanping injection; n=36) and a control group (conventional treatment alone; n=37) in a 1:1 ratio. Xiyanping injection was administered at a dose of 0.3 mL/(kg·d) (total daily dose ≤8 mL), twice daily via intramuscular injection, with a treatment duration of ≤4 days and a follow-up period of 7 days. The treatment efficacy and safety were compared between the two groups.@*RESULTS@#The total effective rate on the 3rd day after treatment in the test group was significantly higher than that in the control group (P<0.05), while there was no significant difference in the total effective rate on the 5th day between the two groups (P>0.05). The rates of fever relief, cough relief, and lung rale relief in the test group on the 3rd day after treatment were higher than those in the control group (P<0.05). The cough relief rate on the 5th day after treatment in the test group was higher than that in the control group (P<0.05), while there was no significant difference in the fever relief rate and lung rale relief rate between the two groups (P>0.05). The cough relief time, daily cough relief time, and nocturnal cough relief time in the test group were significantly shorter than those in the control group (P<0.05), while there were no significant differences in the fever duration and lung rale relief time between the two groups (P>0.05). There was no significant difference in the incidence of adverse events between the two groups (P>0.05).@*CONCLUSIONS@#The overall efficacy of combined routine treatment with intramuscular injection of Xiyanping injection in the treatment of acute bronchitis in children is superior to that of routine treatment alone, without an increase in the incidence of adverse reactions.

Objective:To explore the distribution characteristics of brachial-ankle pulse wave velocity (BaPWV) in adolescents.Methods:Cross sectional survey research.A total of 1 607 adolescents aged 12-17 years from 5 middle schools in the Haidian District, Beijing from June 2020 to May 2021 were enrolled for measuring their blood pressure, weight, height and the body mass index (BMI), including 782 males and 825 females.BaPWV was measured using an arteriosclerosis detector.They were divided by the age, sex and obesity.Differences of measurement data among multiple groups were compared by one-way ANOVA, followed by the LSD test, and those between groups were compared by the two-sample t-test.The correlation between BaPWV and other indexes was assessed by the Pearson correlation analysis. Results:The median level of BaPWV in adolescents aged 12-17 years increased with age, which was 982.50 cm/s in adolescents aged 12 years, and maximum 1 113.50 cm/s those aged 17 years.BaPWV in adolescents aged 12-17 years was positively correlated with age ( r=0.936, P=0.006). Subgrouped by the sex, the median BaPWV of male and female adolescents aged 12 years was 962.25 cm/s and 997.50 cm/s, respectively, which reached 1 122.50 cm/s and 1 096.00 cm/s in those aged 17 years, respectively.BaPWV of male and female adolescents was positively correlated with the age ( r=0.903, P=0.014; r=0.945, P=0.004). In male adolescents, BaPWV was positively correlated the systolic and diastolic blood pressure, age, weight, height, BMI( r=0.308, P<0.001; r=0.289, P<0.001; r=0.478, P<0.001; r=0.190, P<0.001; r=0.315, P<0.001; r=0.109, P=0.002). In female adolescents, BaPWV also was positively correlated the systolic and diastolic blood pressure, age, weight, height, BMI( r=0.340, P<0.001; r=0.285, P<0.001; r=0.379, P<0.001; r=0.115, P=0.001; r=0.170, P=0.001; r=0.097, P=0.014). In the overall population, BaPWV was statistically significant between the obese and normal groups ( t=-3.428, P=0.001). No significant difference in BaPWV between male and female adolescents aged 12-13 years was identified ( t=0.123, P=0.902 ), but it was significantly lower in female adolescents aged 14-15 years and 16-17 years than those of age-matched males( t=2.315, P=0.021; t=2.152, P=0.032). Conclusions:The median BaPWV level in adolescents aged 12-17 years, increases with the age.Systolic blood pressure, diastolic blood pressure, body weight, BMI, age and height are positively correlated with BaPWV in adolescents.Obesity can increase the stiffness of blood vessels, which is influenced by the sex.

RESUMO
Objective To understand the risk situation of imported schistosomiasis and its main influencing factors in Shang-hai City from 2005 to 2015. Methods A retrospective survey was performed,and the database was established based on the da-ta collection of imported schistosomiasis,Oncomelania hupensis snail situation and mobile population in Shanghai City from 2005 to 2015. Results From 2005 to 2015,the mobile population in Shanghai City increased by 123.92％,which reached about 9816500,and 54.70％of them were located in the inner suburban districts. The accumulated areas with snails of 7.13 hm2 were found in 16 towns of 4 outer suburbs(excluding Chongming District). A total of 23 cases of imported schistosomiasis were found in Shanghai City,and the number of the imported schistosomiasis cases was on the downward trend(rs=-0.782,P=0.004). From 2005 to 2009,11 out of 13 imported schistosomiasis cases(84.62％)were distributed in the inner suburban dis-tricts where no O. hupensis snails were found at the same time. From 2010 to 2015,9 out of 10 imported schistosomiasis cases (90％)were distributed in the outer suburban districts where O. hupensis snails were found at the same time. Conclusion The number of imported schistosomiasis cases in Shanghai is on the downward trend. However,the threat of imported schistosomiasis to the prevention and control of schistosomiasis in Shanghai City should not be ignored.

RESUMO
<p><b>BACKGROUND</b>Macrophage-inducible C-type lectin (MINCLE) is an important member of C-type lectin superfamily, which has been shown evidence for susceptibility to arthritis in animal models. We aimed to investigate the possible association of MINCLE with rheumatoid arthritis (RA) susceptibility in Chinese Han population.</p><p><b>METHODS</b>Haplotypes from HapMap database (Chinese Han Beijing, CHB) were used to select tag-single nucleotide polymorphism (SNP) (r(2) = 0.8) residing in MINCLE gene. A total of 563 patients with RA and 404 healthy controls were TagMan genotyped for SNP rs10841845. Association analyses were performed on the whole data set and on RA subsets based on gender difference and the status of anti-cyclic citrullinated peptide (anti-CCP) antibody in RA patients. Association statistics were calculated by age and sex adjusted logistic regression.</p><p><b>RESULTS</b>Overall, MINCLE SNP rs10841845 was not associated with susceptibility to RA. However, following anti-CCP stratification, rs10841845 GG genotypes conferred a significantly protective effects against anti-CCP-positive RA (OR 0.65, 95%CI 0.430 - 0.995, P = 0.048). Following gender stratification, SNP rs10841845 G allele appeared to insert its RA protective effect only in male patients, both at allele level (G vs. A OR 0.66, 95%CI 0.46 - 0.93, P = 0.018) and at genotype level (GG vs. AA+AG, OR 0.429, 95%CI 0.20 - 0.95, P = 0.036). Notably, the male RA protective effect of rs10841845 G allele was only seen in anti-CCP-positive RA (G vs. A: OR 0.64, 95%CI 0.43 - 0.96, P = 0.029; GG vs. AA+AG: OR 0.375, 95%CI 0.14 - 0.94, P = 0.038). Furthermore, we observed a significant reduction of Disease Activity Score (DAS) 28 score (3.91 ± 0.70 vs. 5.66 ± 0.31, P = 0.022) and serum C-reactive protein levels (31.64 ± 24.13 vs. 91.80 ± 12.02, P = 0.012) in male anti-CCP-positive RA patients carrying rs10841845 GG genotype, compared with patients carrying AA+AG genotypes.</p><p><b>CONCLUSIONS</b>Our study provides the evidence for a gender specific association between MINCLE rs10841845 and RA susceptibility. The SNP rs10841845 G allele appears to have protective effect against anti-CCP-positive RA and confer reduced RA activity in men.</p>

<p><b>BACKGROUND</b>Antibodies against type 3 muscarinic acetylcholine receptor (M3R) are involved in the pathogenesis of Sjögren's syndrome (SS), but the clinical value of them in SS patients has been controversial. The aims of this study were to: (1) establish an improved enzyme-linked immunosorbent assay (ELISA) to detect IgA antibodies against M3R; (2) evaluate the value of IgA antibodies against the second extracellular loop of M3R205-220 (c2M3RP) in diagnosis of SS.</p><p><b>METHODS</b>To increase the ELISA sensitivity, c2M3RP was coupled to bovine serum albumin (BSA) by the glutaraldehyde method and a 96-well microplate was treated by ultraviolet rays before coated. Concentrations of anti-c2M3RP, anti-SSA, and anti-SSB were measured in the sera of 240 individuals: 91 patients with primary SS and 149 controls (16 secondary SS, 27 systemic lupus erythematosus, 40 rheumatoid arthritis and 66 healthy controls). Diagnostic properties of anti-c2M3RP were determined by receiver-operating characteristic curve analysis.</p><p><b>RESULTS</b>The prevalence of serum IgA anti-c2M3RP antibodies in patients with pSS (46%, 42/91) was significantly higher than that in patients with systemic lupus erythematosus (19%, 5/27), in rheumatoid arthritis (15%, 6/40) and in healthy controls (5%, 3/66). However, there was no significant difference between the two SS groups (P = 0.727). The diagnostic performance of IgA anti-M3RP antibodies was similar to anti-SSA assay, but had 22% higher sensitivity than anti-SSB. By analyzing of IgA anti-c2M3RP antibodies, combination of anti-SSA and anti-SSB resulted in increased sensitivity, whereas their specificity was not significantly changed.</p><p><b>CONCLUSIONS</b>The improved anti-c2M3RP ELISA is a novel, sensitive, and specific serological test for the diagnosis of SS. The combined application of anti-c2M3RP, anti-SSA and anti-SSB tests can improve the laboratory diagnosis of SS. The IgA anti-c2M3RP antibodies may serve as a novel diagnostic marker for SS.</p>
