Interleukin-33 (IL-33), a novel identified member of IL-1 superfamily, is involved in the development and progress of various immune-related diseases, including inflammatory bowel disease (IBD), via its receptor ST2-mediated pathway, but the mechanism is not fully clarified. It has been reported that IL-33 plays a dual role in promoting inflammation and inducing protective effect in intestinal mucosa. This article reviewed the relationship between IL-33/ST2 signal pathway and IBD.

Background: As a routine examination, peripheral blood leukocytes or white blood cell count is considered to be a simple biological marker for inflammatory diseases; neutrophil and peripheral blood mononuclear cells are also closely related to the activity and severity of various diseases. Aims: To investigate the clinical significance of peripheral blood neutrophil/lymphocyte ratio (NLR) and monocyte/lymphocyte ratio (MLR) in ulcerative colitis (UC). Methods: A total of 62 patients with UC from October 2017 to July 2019 at the Second Affiliated Hospital of Zhengzhou University were collected. Forty-two individuals accepting physical examination were served as control group. Neutrophil count, monocyte count, lymphocyte count, NLR, MLR were compared between the two groups, and their correlations with C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), Mayo score, UCEIS score were analyzed. ROC curve was used to analyze the efficacy of the parameters for diagnosis of UC. Results: Compared with controls, neutrophil count, monocyte count, NLR and MLR in UC patients were significantly increased (P<0.05), while lymphocyte count was significantly decreased (P<0.05). Compared with mild UC, neutrophil count, monocyte count, NLR and MLR in moderate to severe UC were significantly increased (P<0.05), while lymphocyte count was significantly decreased (P<0.05). Neutrophil count, monocyte count, NLR and MLR were positively correlated with CRP, ESR, Mayo score and UCEIS score, while lymphocyte count was negatively correlated with above-mentioned indices (P<0.05). When the cut-off value was 0.470, the sensitivity of NLR for diagnosing UC was 0.613, the specificity was 0.857, AUC was 0.731 (95% CI: 0.636-0.827); when the cut-off value was 0.439, the sensitivity of MLR for diagnosing UC was 0.629, the specificity was 0.810, AUC was 0.726 (95% CI: 0.630-0.822). Conclusions: NLR and MLR are elevated in patients with UC, and can reflect the disease activity, which may be used as a serum marker for diagnosis and evaluation of UC.

Objective To investigate the mobility of the lung tumors in order to guide the margin that CTV is to be expanded to PTV during stereotaetic radiotherapy for lung tumors.Methods Eighty-three lung tumom ineluded,in which 7 invaded the chest wall.1-2 gold marker(s)was/were implanted into or nearby the tumor.The motion of lung tumors in x(right-left),y(superior-inferior)and:(anterior-posterior)directions were measured via X-ray simulator system.One week later,1.25 mm thick of 16-slice spiral CT lung scan were taken.Apex,middle,and bottom of the lung were classified according to anatomic boderlines.Results No significant difference was detected among movements of apex,middle and bottom of the lung lesions in x axis direction((1.6±0.8),(2.6±1.1),(2.8±1.7)mm,respectively(F=1.76,P=0.179))and,y axis direction((2.0±1.3),(4.3±2.8),(4.0±2.0)mm,respectively(F=2.06,P=0.135))in 76 lesions of 63 patients.Significant differences were detected in:axis((2.7±0.8),(7.3±3.6),(12.0±5.3)mm(F=16.33,P=0.000)).The mobilities of the 7 lesions of 7 patients invading the chest wall were very small in all directions(0.9±0.7,0.7±0.7.and 2.0±0.6 mm,respectively).Motion amplitude did not correlate with the sex,age,height,weight and FEV1/FVC(r=-0.001-0.136.all P>0.05).Conclusions Motion amplitude of lung tumor due to breathing is associated with tumor loeation and status of chest wall invoivement.Identification of the mobile rules and the influencing factors is important for the internal margin set-up in lung tumor radiotherapy.

Objective To evaluate the clinical efficacy of small endoscopic sphincterotomy combined large-bal-loon dilation in treatment of common bile duct stones 1.0~2.5 cm in diameter. Methods 426 patients with large common bile duct (CBD) stones 1.0~2.5 cm in size were reviewed in our hospital between June 2010 and June 2014. They were randomized underwent small endoscopic sphincterotomy combined large-balloon dilation (SESPLBD) (n=218) or endoscopic sphincterotomy (EST) ( n= 208) for lithotripsy. The therapeutic outcome and complications were reviewed and compared. Results SESPLBD had higher complete duct clearance in one session (95.41 % vs. 93.75%), but there was no statistical significant difference. Bleeding was much less occurred in SESPLBD than in EST (2.29 % vs. 7.69 %, P= 0.025), especially when the stones were bigger than 1.5 cm in diameter. Mechanical lithotripsy was performed less in SESPLBD (13.76%vs 25.96 %, P=0.002), especially when the stones were 1.5 ~2.0 cm in diameter. There was no statistical significant difference in the incidence rate of post-ERCP pancreatitis (9.17 % vs. 6.73 %,P = 0.452), hyperamylasemia (19.72 % vs. 18.27 %,P = 0.796), perforation and death. Conclusions SESPLBD could be a safe method for large bile duct stones 1.0~2.5 cm in size. Compared with routine EST, it had less bleeding rate and mechanical lithotripsy requirement without increasing the incidence rate of post-ERCP pancreatitis or hyperamylasemia.

Diabetic cardiomyopathy(DCM)is a unique myocardial disease caused by diabetes mellitus,which can increase the risk of heart failure and death,and is one of the main causes of death of diabetes mellitus patients worldwide.Although the research on the pathogenesis of DCM has made great progress,it has not yet been fully clarified.Many studies have shown that long noncoding RNAs(lncRNAs)can interact with microRNAs(miRNAs)as competitive endogenous RNAs(ceRNAs),participate in the regulation of gene expression,and then affect the development of DCM.This article gives an overview of lncRNAs and its biological functions as well as ceRNA hypothesis,and focuses on the role of lncRNAs as ceRNAs in regulating the occurrence and development of DCM.

Objective: To investigate the prevalence and associated factors of spinal curvature abnormalities among primary and secondary school students in the Guangxi Zhuang Autonomous Region, so as to provide a scientific basis for the prevention and control of such abnormalities. Methods: From September to November 2023, adopting a stratified cluster random sampling method, spinal curvature screenings and questionnaire surveys were conducted among 168 931 students from grade 4 of primary school to grade 12 of high school in 111 districts and counties across 14 cities in Guangxi. Chi square tests and binary Logistic regression analysis were used to analyze influencing factors of spinal curvature abnormalities. Results: In 2023, the detection rate of poor posture among students above grade 4 in Guangxi was 4.24% , and the detection rate of spinal curvature abnormalities was 2.13%. The detection rate was higher among urban students (2.84%) than rural students (1.66%), boarding students (2.61%) than non-boarding students (1.60%), and high school students (3.16%) than junior high (2.45%) and primary school students (1.15%), and the differences were statistically significant ( χ 2=269.85, 221.44, 565.10, P <0.01). A trend of increasing detection rates with higher grade levels was observed ( χ 2 trend =617.63, P <0.01). Binary Logistic regression analysis indicated that students without boarding at school ( OR =0.82, 95% CI =0.75-0.90), engaging in high-intensity physical activity for over 60 min per day ≥5 days per week ( OR =0.90, 95% CI =0.82-0.98), and adequate sleep ( OR =0.87, 95% CI =0.81-0.94) had lower risks of detecting spinal curvature abnormalities ( P <0.05). Conclusions The prevalence of spinal curvature abnormalities increases with grade level among primary and secondary school students in Guangxi. Regular moderate-to-vigorous physical activity demonstrates protective effects against spinal abnormalities.

Objective: To explore the comorbidity and associated factors of dental caries and overweight/obesity among primary and secondary school students in Guangxi, so as to provide a scientific basis for the development of targeted prevention strategies. Methods: A stratified cluster random sampling method was used to survey 178 700 students from the fourth grade of primary school to the third year of high school in Guangxi Zhuang Autonomous Region from September to November 2023, including physical examination, oral screening, and questionnaire survey. Chisquare tests and binary Logistic regression analysis were employed to investigate the related factors of the cooccurrence of dental caries and overweight/obesity among students. Results: The comorbidity rate of dental caries and overweight/obesity was 9.55%, with urban areas (9.95%) higher than rural counties (9.24%), boys (10.54%) higher than girls (8.54%), primary school students (11.49%) higher than senior high school students (8.92%) and junior high school students (8.05%), and nonboarding students (11.44%) higher than boarding students (7.94%), and all differences were statistically significant (χ2=26.07, 207.91, 471.54, 629.14,P<0.01). Multivariate Logistic regression analysis showed that consuming cereal for breakfast (OR=0.91, 95%CI=0.88-0.94), drinking milk in the past week (OR=0.89, 95%CI=0.83-0.95), meeting sleep standards (OR=0.95, 95%CI=0.91-0.99), and brushing teeth at least once a day (OR=0.82, 95%CI=0.73-0.93) had a lower risk of the comorbidity of dental caries and overweight/obesity. In contrast, drinking beverages in the past week (OR=1.14, 95%CI=1.09-1.20), consuming fried foods in the past week (OR=1.11, 95%CI=1.06-1.17), eating fruit ≥1 time every day (OR=1.06, 95%CI=1.02-1.11), consuming fruit ≥1 type every day (OR=1.07, 95%CI=1.01-1.12), and having fish, poultry, meat, or eggbased breakfasts (OR=1.03, 95%CI=1.05-1.13) had a higher risk of the comorbidity of dental caries and overweight/obesity (P<0.05). Conclusions Dietary habits and lifestyle behaviors are associated with the comorbidity of dental caries and overweight/obesity among primary and secondary school students in Guangxi. Guiding students to form healthy living habits is helpful to preven dental caries and overweight/obesity.

Objective: To investigate the association between medium to long term PM 2.5 exposure around school areas and overweight/obesity among primary and secondary school students in Guangxi, providing data support and theoretical foundations for scientifically addressing overweight and obesity in primary and secondary school students. Methods: From September to November 2023, a stratified cluster random sampling method was employed to select 251 183 students aged 7-18 years (grade 1 to grade 12) from 14 prefecture level cities (111 districts and counties) in Guangxi. PM 2.5 mass concentration data were obtained from the Tracking Air Pollution in China (TAP) dataset. Preliminary comparative analysis was conducted using the Mann-Whitney U test, while binary Logistic regression models were applied to quantify the relationship between PM 2.5 exposure and overweight/obesity. Restricted cubic spline analysis was further utilized to examine the nonlinear association between PM 2.5 concentration and overweight/obesity risk. Results: The detection rate of overweight/obesity among Guangxi students in 2023 was 19.5%. The median PM 2.5 concentration in the year prior to the study was higher in the overweight/obesity group (23.22 μg/m 3) compared to the non overweight/obesity group (22.63 μg/m 3) ( Z=-15.66, P <0.01), and consistent trends were observed across gender (male/female) and educational stage (primary/junior/senior high school) subgroups (all P <0.01). Binary Logistic regression revealed that for every 10 μg/m 3 increase in the annual average PM 2.5 concentration, the risk of overweight/obesity increased by 12% ( OR=1.12, 95%CI=1.09- 1.15 , P <0.01). Restricted cubic spline analysis indicated a nonlinear relationship between monthly PM 2.5 levels and overweight/obesity risk ( P trend <0.01). Below 22.68 μg/m 3, PM 2.5 exposure showed no significant association with obesity risk; above the threshold, the risk increased with rising PM 2.5 levels. Conclusion Medium to long term PM 2.5 exposure around school environments is significantly associated with overweight/obesity among primary and secondary school students.

Galectin⁃3 is an endogenous lectin with extensive immunomodulatory effects, and plays an important role in inflammatory response, autoimmunity and tumorigenesis. However, the expression of galectin⁃3 in ulcerative colitis (UC) and its relationship with disease activity of UC are unclear. Aims: To detect the expression of galectin⁃3 in colon tissue and serum in UC patients, and explore the relationship between galectin⁃3 and disease activity. Methods: Thirty⁃ three patients with UC diagnosed and treated from March 2019 to December 2019 at the Second Affiliated Hospital of Zhengzhou University were recruited, and 20 paracancerous normal tissue of colon cancer patients were served as controls. The expression of galectin ⁃ 3 in colon tissue was detected by immunohistochemistry SABC. Serum samples of 24 UC patients and 20 healthy controls were collected. Serum level of galectin⁃3 was detected by ELISA. Results: The positive expression rate of galectin⁃3 in colon tissue in UC patients was significantly lower than that in paracancerous normal tissue, and the difference was statistically significant (P<0.05). The positive expression rate in mild UC patients was higher than that in moderate to severe UC patients, and the difference was statistically significant (P<0.05). The positive expression rate in remission stage was higher than that in active stage, and the difference was statistically significant (P<0.05). Serum galectin⁃3 level in UC patients was higher than that in healthy control group, and the difference was statistically significant (P<0.05). Serum galectin ⁃ 3 level in moderate to severe UC patients was higher than that in mild UC group, and the difference was statistically significant (P<0.05). Serum galectin ⁃ 3 level in active UC patients was higher than that in remission UC patients, and the difference was statistically significant (P<0.05). Conclusions: In UC patients, the expression of galectin⁃3 in colon tissue and serum are dysregulated, and the expression of galectin⁃3 in colon tissue is decreased, especially in moderate to severe UC, while the serum galectin⁃3 level is opposite to the tissue expression.

Objective To investigate the antimicrobial resistance profile of the clinical isolates collected from selected hospitals across China. Methods Twenty-nine general hospitals and five children's hospitals were involved in this program. Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or automated systems. Results were interpreted according to CLSI 2017 breakpoints. Results A total of 190 610 clinical isolates were collected from January to December 2017, of which gram negative organisms accounted for 70.8％ (134 951/190 610) and gram positive cocci 29.2％ (55 649/190 610). The prevalence of methicillin-resistant strains was 35.3％ in S. aureus (MRSA) and 80.3％ in coagulase negative Staphylococcus (MRCNS) on average. MR strains showed much higher resistance rates to most of the other antimicrobial agents than MS strains. However, 91.6％ of MRSA strains were still susceptible to trimethoprim-sulfamethoxazole, while 86.2％ of MRCNS strains were susceptible to rifampin. No staphylococcal strains were found resistant to vancomycin. E. faecalis strains showed much lower resistance rates to most of the drugs tested (except chloramphenicol) than E. faecium. Vancomycin-resistant Enterococcus (VRE) was identified in both E. faecalis and E. faecium. The identified VRE strains were mainly vanA, vanB or vanM type based on phenotype or genotype. The proportion of PSSP or PRSP strains in the non-meningitis S.pneumoniae strains isolated from children decreased but the proportion of PISP strains increased when compared to the data of 2016. Enterobacteriaceae strains were still highly susceptible to carbapenems. Overall, less than 10％ of these strains (excluding Klebsiella spp.) were resistant to carbapenems. The prevalence of imipenem-resistant K. pneumoniae increased from 3.0％ in 2005 to 20.9％ in 2017, and meropenem-resistant K. pneumoniae increased from 2.9％ in 2005 to 24.0％ in 2017, more than 8-fold increase. About 66.7％ and 69.3％ of Acinetobacter (A. baumannii accounts for 91.5％) strains were resistant to imipenem and meropenem, respectively. Compared with the data of year 2016, P. aeruginosa strains showed decreasing resistance rate to carbapenems. Conclusions Bacterial resistance is still on the rise. It is necessary to strengthen hospital infection control and stewardship of antimicrobial agents. The communication between laboratorians and clinicians should be further improved in addition to surveillance of bacterial resistance.
