Objective To study the association between serum interleukin-33 (IL-33) level and human stromelysin-2 (ST2) level in patients with rheumatoid arthritis (RA) associated with interstitial lung disease (RA-ILD) and its correlation with lung function and other laboratory parameters.Methods Two hundred and forty-five newly diagnosed RA patients during March 2012 to March 2013 in the in-patient and out-patient clinic of the First Affiliated Hospital of Liaoning Medical College were enrolled into this study.Patients were further divided into RA group (n=187) and RA-ILD group (n=58).Sixty subjects who came to the hospital for routine health check-up was composed of the normal control group.The clinical data of the two groups and controls were collected and their serum IL-33 and ST2 concentrations were measured.The t test was used to compare the difference between the two groups.Multiple variance analysis was used to com-pare the difference between groups.Pearson's correlation analysis was applied to explore the relationship between IL-33 concentrations and related variables.Results ① This study showed that the prevalence of RA associated interstitial lung disease was 23.7％(58/245).② The concentration of IL-33 [(746±43) pg/ml] and ST2 [(3413±169)pg/ml] of the RA-ILD group was significantly higher than that of the RA group [(433±42) pg/ml,(1500±147) pg/ml] (P＜0.01).③The vital capacity (VC％),forced vital capac-ity (FVC％),maximal midexpiratary flow curve (MMF％) and carbon monoxide diffusing capacity (DLCO) of the RA-ILD group were significantly lower than those of the RA group.④ The serum level of IL-33 was negatively correlated with that of RF and ACPA (IL-33 and RF,r=0.82,P＜0.01; IL-33 and ACPA,r=0.55,P＜0.01).Serum level of IL-33 was negaitively correlated with DLCO (r=-0.80,P＜0.01).Conclusion IL-33 participates in the pathogenesis of RA; and may be involved in the pathogenesis of RA-ILD.

Background:Preterm premature rupture of membranes (PPROM) is associated with high neonatal morbidity and mortality.However,the influences of cesarean section (CS) on neonatal outcomes in preterm pregnancies complicated with PPROM are not well elucidated.The aim of this study was to investigate the influence of delivery modes on neonatal outcomes among pregnant women with PPROM.Methods:A retrospective cross-sectional study was conducted in 39 public hospitals in 14 cities in the mainland of China from January 1st,2011 to December 31st,2011.A total of 2756 singleton pregnancies complicated with PPROM were included.Adverse neonatal outcomes including early neonatal death,birth asphyxia,respiratory distress syndrome (RDS),pneumonia,infection,birth trauma,and 5-min/10-min Apgar scores were obtained from the hospital records.Binary variables and ordinal variables were respectively calculated by binary logistic regressions and ordinal regression.Numerical variables were compared by multiple linear regressions.Results:In total,2756 newborns were involved in the analysis.Among them,1166 newborns (42.31％) were delivered by CS and 1590 newborns belonged to vaginal delivery (VD) group.The CS proportion of PPROM obviously increased with the increase of gestational age (X2 =5.014,P =0.025).Compared with CS group,VD was associated with a higher risk of total newborns mortality (odds ratio [OR],2.38;95％ confidence interval [CI],1.102-5.118;P =0.027),and a lower level of pneumonia (OR,0.32;95％ CI,0.126--0.811;P =0.016).However,after multivariable adjustment and stratification for gestational age,only pneumonia was significantly related with CS in 28 to 34 weeks group (OR,0.34;95％ CI,0.120-0.940;P =0.038).There were no differences regarding to other adverse outcomes in the two groups,including neonatal mortality,birth asphyxia,Apgar scores,RDS,pneumonia,and sepsis.Condusions:The proportion of CS of pregnant women with PPROM was very high in China.The mode of delivery does not affect neonatal outcomes of pregnancies complicated with PPROM.

Objective To compare the short-term efficacies of laparoscopic adjustable gastric banding (LAGB) and laparoscopic sleeve gastrectomy (LSG) in the treatment of obesity and type 2 diabetes mellitus,and to investigate the relationship between the body weight loss and the decrease of glucose of the 2 treatment methods.Methods The clinical data of 40 patients with obesity combined with type 2 diabetes mellitus who were admitted to the Changhai Hospital of the Second Military Medical University from January 2010 to December 2011 were retrospectively analyzed.There were 14 patients treated by LAGB (LAGB group) and 26 by LSG (LSG group).The body weight loss and the decrease of glucose at postoperative year 1 of the 2 groups were compared.The differences in the body weight and glucose before and after operation within groups were compared using the paired t test,and the differences in the body weight and glucose between the 2 groups were compared using the multiple analysis of variance.The correlation between the body weight loss and the decrease of glucose was analyzed using the linear regression analysis.Results Laparoscopic surgery was successfully done without conversion to open surgery or intraoperative complications.The operation time and volume of blood loss were (69 ± 16)minutes and (31 ± 14)mL in the LAGB group,(120 ± 15) minutes and (148 ± 48) mL in the LSG group.Complications including postoperative malnutrition,electrolyte disturbance,delayed gastric emptying,bleeding,anastomotic leakage did not occurr in the 2 groups.Two patients were complicated with abdominal incision fat liquefaction,and were cured by symptomatic treatment.(1) The body weight,body mass index (BMI) and waistline had a decrease trend.The body weight,BMI and waistline in the LAGB group were decreased from (117 ± 28)kg,(40 ± 8)kg/m2 and (118 ± 15) cm before operation to (94 ± 28) kg,(33 ± 8) kg/m2 and (92 ± 15) cm at postoperative week 48.The body weight,BMI and waistline in the LSG group were decreased from (119 ± 25)kg,(42 ± 6)kg/m2 and (123 ± 14)cm before operation to (74± 16)kg,(26± 4)kg/m2 and (86 ± 13)cm at postoperative week 48.The EWL had an increase trend in the 2 groups.The EWL in the LAGB group was increased from 7％ ± 2％ at postoperative week 1 to 53％± 24％ at postoperative week 48,and the EWL in the LSG group was increased from 11％ ± 4％ at postoperative week 1 to 90％ ± 20％ at postoperative week 48.There were significant differences in the changes of body weight,BMI,waistline and EWL between the 2 groups (F =60.660,74.490,57.650,90.020,P ＜ 0.05).(2) The levels of glycosylated hemoglobin,fasting glucose,fasting insulin,HOMA-IR,triglyceride,total cholesterol,low-density lipoprotein and high density lipoprotein in the LAGB group were decreased from 8.1％± 0.8％,(8.4±0.6)mmol/L,(21±8)μmol/L,7.9 ±2.9,(1.68±0.50)mmol/L,(6.0±1.1)mmol/L (4.1 ± 0.8) mmol/L,(1.09 ±0.15)mmol/L to 6.4％ ±0.8％,(6.3 ±0.3) mmol/L,(10 ± 3) μmol/L,2.7 ±0.9,(1.04 ± 0.09) mmol/L,(4.3 ± 0.8) mmol/L,(2.3 ± 0.4) mmol/L,(1.22 ± 0.09) mmol/L at postoperative week 48 ; the levels of glycosylated hemoglobin,fasting glucose,fasting insulin,HOMA-IR,triglyceride,total cholesterol,low-density lipoprotein and high density lipoprotein in the LSG group were changed from 7.9％ ± 1.0％,(9.0±1.0)mmol/L,(21 ±9) μ mol/L,8.5 ±3.5,(2.09 ± 0.70) mmol/L,(6.0 ± 1.2)mmol/L,(3.9 ± 1.1) mmol/L,(1.06 ± 0.21) mmol/L before operation to 5.1％ ± 0.8％,(5.2 ± 0.4) mmol/L,(4 ± 1)μmol/L,0.9±0.2,(1.22±0.17)mmol/L,(4.2±0.8)mmol/L,(2.3 ±0.6)mmol/L,(1.30±0.13)mmol/L at postoperative week 48.There was a decrease trend of the glycosylated hemoglobin,fasting glucose,fasting insulin,HOMA-IR,trigluceride,total cholesterol and low density lipoprotein and a increase trend of the high density lipoprotein in the 2 groups.There were significant differences in the levels of glycosylated hemoglobin,fasting glucose,fasting insulin,HOMA-IR,triglyceride,total cholesterol,low-density lipoprotein and high density lipoprotein between the 2 groups (F =57.650,74.270,36.750,42.960,10.870,30.650,32.560,11.490,P ＜0.05).The levels of glucose of the LAGB group at postoperative month 1 and 3 were influenced by BMI (b =0.543,0.753,P ＜ 0.05),while the levels of glucose of the LAGB group did not be influenced by BMI at postoperative month 6 and year 1 (b =0.130,0.222,P ＞0.05).The levels of glucose of the LSG group did not be influenced by BMI at postoperative month 1,3,6 and year 1 (b =0.185,0.035,0.212,0.126,P ＞0.05).Conclusions The efficacy of LSG is superior to LAGB for the treatment of obesity combined with type 2 diabetes mellitus.The efficacy of LAGB is correlated with the change of body weight,while the efficacy of LSG does not correlated with the change of body weight.

Objective To investigate the incidence and pregnancy outcomes of premature rupture of membranes (PROM) in pregnant women in Beijing.Methods A retrospective multicenter study of 18 534 cases delivered in Beijing Obstetrics and Gynecology Hospital,Beijing Friendship Hospital,Daxing MCH Hospital and Tongzhou MCH Hospital from January 2011 to December 2011,was conducted.Results Among 18 534 cases,PROM occurred in 4 504 cases (24.30％),including 3 910 cases of in term PROM (21.10％) and 594 cases of preterm PROM (3.20％).The incidence of premature delivery was 6.17％ (1 144/18 534),and among 1 144 cases of premature delivery 547 cases were PROM (47.81％);the incidence of PROM was 22.75％ (3 957/17 390) in term delivery.The overall cesarean section (CS) rate was 48.50％ (8 989/18 534) and that in pregnant women with PROM was 35.55％ (1 601/4 504),but the CS rate in pregnant women without PROM was 52.66％ (7 388/14 030).The rate of postpartum hemorrhage was 13.12％ (210/1 601)in CS cases and 4.17％ (121/2 903) in vaginal delivery cases (x2 =121.361,P=0.000).The mean hospital stay for PROM was (5.3±2.9) d in CS cases and (4.3±2.3) d in vaginal delivery cases (t =-12.136,P =0.000).Conclusions Without severe maternal or fetal complications,the incidence of PROM is relatively high in Beijing region and PROM may not increase the maternal or fetal complications.Vaginal delivery is the main mode of delivery for PROM.Cesarean section may not cause less neonatal complications,but may lead to more postpartum hemorrhage and longer hospital stay.

SUMOylation is a post - translational modification consisting of covalent conjugation of ubiquitin - like proteins called small ubiquitin related modifier ( SUMO ) . SUMO modification has been shown to significantly alter protein activity, which can modulate protein stability, affect protein-protein interactions, and modify protein localization and trafficking. This process adds another layer of control in eukaryote gene expression, and it regulates both transcriptional activation and repression. This article reviews the current situation and future development of SUMOylation in ophthalmology.
