Objective To assess the lipid profiles of obese patients undergoing laparoscopic gastric by-pass surgery.Methods A retrospective observational study was performed , involving 25 patients(BMI>28 kg/m2 ) who consecutively underwent gastric bypass surgery in the First Affiliated Hospital of Nanjing Medical Univer -sity from Oct.2010 to Dec.2012.For the surgery, a small gastric pouch about 30 ml was performed with 100 cm biliopancreatic limb and 100-200 cm alimentary limb.Total cholesterol(TC),triglycerides(TG),high density lip-oprotein( HDL) and low density lipoprotein ( LDL) at baseline and 1, 3, 6, 9 and 12 months after surgery were measured.Related complications were recorded .Results All surgeries were performed laparoscopically and no serious complications occurred .TC, TG, and LDL significantly reduced after the surgery (P<0.05 for all).In-versely, HDL disclosed a significant rise(P<0.05).Of the lipid profiles at baseline, only HDL concentration displayed a correlation with BMI .Percentage of excess weight loss ( PEWL ) displayed significant correlation with the variety of TG、LDL、HDL after surgery(P<0.05 for all).Conclusions Laparoscopic gastric bypass is a safe operation which improves the lipid metabolism of obese patients .The operation can decrease the concentration of TC, TG, LDL and increase HDL level .

Objective To observe the adjuvant therapy efficacy of Saccharomyces boulardii sachets in liver cirrhosis patients with spontaneous bacterial peritonitis(SBP).Methods 72 liver cirrhosis patients with SBP were randomly divided into the observation group and control group.The patients in the control group (30 cases) were giv-en routine medical treatment such as anti-infection,correction of hypoproteinemia,liver protection,and diuresis,etc. At the base of the control group,the patients in the observation group (32 cases) were orally given Saccharomyces boulardii ( Baili Pharmaceutical Factory,French) 0.5g for one time,two times daily for 10 days.The changes of serum interleukin-6(IL-6),pmcalcitonin (PCT) and hypersensitive c-reactive protein (hs-CRP) levels in the two groups were observed and compared before and after treatment, and curative effect and safety were also observed. Results Before treatment,the serum IL-6,PCT and hs-CRP levels in the two groups had no obviously statistical difference(all P>0.05),but after treatment,the serum IL-6,PCT and hs-CRP levels of the observation group were much lower than those of the control group[(60.50 ±19.10) pg/mL vs (98.32 ±17.20) pg/mL,(1.80 ± 0.34)μg/L vs (6.38 ±3.56)μg/L,(6.20 ±4.15) mg/L vs (20.28 ±8.30) mg/L,t=8.147,7.246,8.529,all P<0.01].Meanwhile,the total effective rate of the observation group was significantly higher than that of the control group(93.75%vs 73.33%,χ2 =4.771,P<0.05).The incidence rate of DAR between the two groups had no obvi-ously statistical difference(9.38% vs 13.33%,χ2 =0.242,P>0.05).Conclusion Saccharomyces boulardii can significantly reduce serum IL-6,PCT and hs-CRP levels of liver cirrhosis patients with SBP,and reduce inflamma-tion reaction to control development of SBP.

Objective To compare the difficult degree,differences in gastric pouch volume,the complications,and postoperative weight loss effect of two gastric pouch practices in laparoscopic gastric bypass for bariatrics.Methods We retrospectively analyzed laparoscopic gastric bypass surgery in 76 bariatrics cases from May 2010 to May 2012.Two methods were used to create gastric pouch,among which 39 cases were operated with the dissection landmark method (called dissection),and 37 cases with bougie airbags 30 ml (called the bougie).Parameters were compared between the 2 groups including operation time for gastric pouch,the amount of staple cartridges,intraoperative complications,blood loss,and postoperative excess weight loss percentage (EWL ％),the postoperative bleeding,obstruction,fistula and other complications.Results All patients were followed up for more than one month.The dissection group used longer time in creating gastric pouch than that in the bougie group [(58 ± 27) min,(42 ±21) min,P ＜ 0.01].The number of staple cartridges used were significantly different between the two groups [(6.2 ±3.0),(4.3 ± 2.0),P ＜ 0.01].There were 10 cases of complications in the dissection group (26％),and 3 cases in the bougie group (8％) (P ＜0.05).One month after the surgery,one each patient had transient hematochezia.There was no gastric pouch-related complications in the two groups postoperation.There was no difference in excess weight loss (P ＞ 0.05).Conclusions The two methods can achieve the same effect on excess weight loss.The bougie method used less time in creating the gastric pouch,less consumable materials,and less complications occurred in creating gastric pouch.

Objective To investigate the clinical significance of CD28 expression on peripheral blood T lymphocytes in children with juvenile idiopathic arthritis (JIA).Methods Flow cytometry and tri-color direct immunofluorescence were used to examine CD3 + T lymphocyte subsets and CD28 expression in whole blood (using the no-wash method) from 36 children with JIA.Results During the active phase of disease,the frequency of CD28 + expression on both CD4 + and CD8 + T cells in the peripheral blood of children with JIA was significantly lower than in normal controls (P ＜ 0.01).The frequency of CD4 + CD28-T cells in the peripheral blood of children with JIA was significantly higher than in normal controls (P ＜ 0.01).CD4 + T cell counts in the peripheral blood of children with JIA,which were mostly of the CD4 + CD28-T cell subtype,were significantly higher than in normal controls (P ＜ 0.01),whereas the CD8 + T cell count was significantly reduced (P ＜0.01).During the resting phase,CD4 +/CD8 + T cell counts and CD28 expression in the peripheral blood of children with JIA were significantly different from normal controls (P ＞ 0.05).Conclusions The frequency of CD4 + CD28-T cells can be used as an indicator of the active phase of JIA.CD4 + T cell and CD4+ CD28-T cell apoptosis was inhibited in JIA patients.These immune-active T lymphocytes with continued survival can promote the occurrence and development of JIA.
