BACKGROUND:Taurine is an important non-enzymatic system antioxidant in the lens.The mechanism of its anti-oxidative effect is mainly to protect lens from oxidative injury by anti-lipid peroxidation.OBJECTIVE:This study was to observe the effect of exogenous taurine on lens epithefial cell apoptosis-induced by H2O2 in vitro.DESIGN:A randomized controlled animal experiment.SETTING:Department of Ophthalmology,Affiliated Hospital of Qingdao University Medical College.MATERIALS:Seventy-five adult New Zealand standard tabbits,of either gender,weighing 1.5-2.5 kg,were provided by Qingdao Laboratory Animal Center.Reagent kit for in situ detecting cell apoptosis(Sigma Company,USA),taurine and H2O2(Shanghai Guangda Chemical Reagent Factory,China)were included in this study.METHODS:This study was performed in the Department of Ophthalmology and Central Laboratory.Affiliated Hospital of Qingdao University Medical College from Mav 2005 to June 2007.Rabbit lenses were harvested and randomly divided into 3 groups:control group,in which,clear lenses were incubated in non-serum and non-phenolsulfonphthalein MEM medium which was renewed every 24 hours,H2O2 group,in which,clear lenses were incubated in non-serum and non-phenolsulfonphthalein MEM medium containing 1 mmol/L H2O2 with addition of 62 μL H202(30 g/L)every 6 hours,and H2O2+taurine group,in which,clear lenses were incubated in non-serum and non-phenolsulfonphthalein MEM medium containing 1 mmol/L H2O2 and 10 g/L taurine.which was renewed every 6 hours.The protocol was conducted in accordance with ethical guidelines for the use and care of animals.MAIN OUTCOME MEASURES:Observation of lens opacity 6.12,24.48 and 72 hours after culture;Lens epithelial cell apoptosis determined by DNA in situ end labeling and DNA fragment analysis.RESULTS:Lens opacity:The lens opacity in the H2O2 group was aggregrated gradually along with the time of oxidative injury.The lens opacity in the H2O2 group was severer than that in the H2O2+taurine group.Lens epithelial cell apoptosis:There were no apoptotic cells in the control group within 72 hours.The number of apoptotic cells in the H2O2 group was increased gradually with the prolonged time of oxidative injury.Till the 72nd hour,the cells were all tamed into apoptotic cells.A few aopototic celIs were found in the H2O2+taurine group since hour 24,and then were more and more,and the number of apoptotic cells accounted for about 30%at hour 72.The apoptotic rate in the H202+taurine group was significantly lower than that in the H2O group at each time point(q=8.6845,P＜0.01).There was no significant difference in apoptotic rate between the H202+taurine group and the control group (P＞0.05). Findings of DNA fragmentation assay:The DNA"ladder"was found in the H2O2 group at hours 24,36,48 and 72,while no DNA"ladder"but only normal electrophoresis straps were present in the other two groups 24 hours after culture.CONCLUSION:Taurine can inhibit the oxidative injury-induced apoptosis of rabbit lens epithelial cells,and alleviate lens opacity.

Anterior shoulder instability is a very difficult issue to treat,especially with glenoid bone defect.When the defect is small,there is little influence on shoulder instability.The larger the defect is,the more influence there will be.Most authors agree that glenoid bone reconstruction should be considered when glenoid bone defect is more than 20％-25％.In this condition soft tissue procedures alone are not enough to provide stability to the shoulder.To date,there is still not an ideal typing of glenoid bone defect.There are many methods of assessing the size of bone defect.Pico system is one of the most common methods,as it is easier and more precise.Numerous surgical procedures have been described to address the bone defect.The Bristow procedure,the Latarjet procedure and the Eden-hybinette procedure are effective and most popular around the world.The Latarjet procedure can provide more bone blocking than the Bristow procedure,and is more popular.The Eden-hybinette procedure dose not need coracoid transfer and then has no damage of normal anatomical structure.But it also lack the hanging effect of the conjoint tendon.After all,each procedure has its advantage and disadvantage in treating anterior shoulder instability associated with glenoid bone defect and should be chosen depending on the characteristics of each patient and the preference of each surgeon.Furthermore,more new and effective treatments are still needed.

OBJECTIVE:To study the effects of Xiaoruzeng capsule on the gastric acid and pepsin in rats. METHODS:Rats were randomized into a blank group (distilled water),a positive control group (3.6 mg/kg omeprazole ) and the groups of low, middle and high doses of Xiaoruzeng capsule [2.25,4.5,9.1 g(crude drug)/kg]. These groups were respectively marked as groups A,B,C,D and E,with 10 rats in each group. All the rats were given corresponding drugs,ig,for consecutive 10 d. Their suc-cus gastricus was collected 3 h after the last administration,and determined for pH value with precision pH test strip and for free acidity and total acidity by acid-base neutralization titration method. The content and activity of pepsin were determined and calculat-ed with the test kit and microplate reader. The pathological change of the stomach was observed under the electron microscope. RE-SULTS:Compared with group A,groups B,C and D had higher pH value of succus gastricus;groups C,D and E had lower free acidity;groups B,C and D had lower total acidity,group E had higher total acidity;groups B,D and E had lower activity of pep-sin;and group C had higher content of pepsin. Compared with group B,group D had lower pH value of succus gastricus;group C had lower total acidity;group E had higher acidity;and groups C,D and E had higher activity of pepsin. There was statistical sig-nificance(P<0.01 or P<0.05). Gastric mucosal erosive haemorrhage was noted in three rats in group E,and other groups demon-strated no obvious pathological change. CONCLUSIONS:Low dose of Xiaoruzeng capsule can slightly inhibit the gastric acid in rats,but will not effect the activity of pepsin.

Objective To explore the clinical characteristics and related factors of Helicobacter pylori (Hp) infection in gastric stump lesion.Methods Eighty-nine patients with subtotal gastrectomy gastrointestinal symptoms underwent gastroscope,the clinical data were retrospectively analyzed.The relationship between gastric Hp infection and different operation reasons,different operation,different degree of inflammation,postoperative time,the existence of bile reflux was assessed.Results There were 29 cases of gastric Hp infection,the positive rate of Hp was 32.6％ (29/89).There were no significant difference between different preoperative disease such as duodenal ulcer (bleeding/perforation),gastric ulcer (bleeding/perforation),gastric cancer,leiomyosarcoma and HP infection (P ＞0.05).There was no significant different positive rate of Hp infection between Billroth Ⅰ and Billroth Ⅱ after operation (P ＞0.05).The rate of Hp infection increased with the degree of inflammation (moderate to severe) in gastric stump and anastomotic inflammation.There were significant difference [gastritis severity of inflammation:27.3％ (12/44) vs.57.1％ (16/28),anastomotic inflammation:25 ％ (10/40) vs.50％ (18/36),P ＜ 0.05] ;there was significant difference between two groups of more than 10 years [43.9％ (18/41)] and less than 10 years [22.9％ (11/48)] of Hp infection rate (x2 =4.433,P =0.035) ; the positive rate of Hp infection in group of no bile reflux under gastroscopy were higher than the group of bile reflux,there was significant difference [22.2％ (10/45) vs.43.2％ (19/44),x2 =4.449,P =0.035).Multivariate Logistic regression analysis showed that,the degree of inflammation (severe) and bile reflux was associated with gastric Hp infection,inflammation (severe) was the dominant risk factor [OR =1.24,95％ CI:1.22-1.56,P =0.01],with bile reflux were protective factors [OR =0.76,95％CI:0.58-0.99,P =0.04].Conclusions Hp infection can promote and aggravate the gastric remnant mucosa inflammation,Hp infection and bile reflux can lead to gastric mucosa pathological changes,there can be independence pathogenic factors,also can cause at the same time,regulate the eradication of residual gastric Hp infection is very important,also deal with the residual stomach regular line of gastroscope and Hp,histologic examination.

Background:Dysregulation of microRNAs is associated with intestinal mucosal barrier injury,intestinal inflammation and intestinal dysfunction. Abnormal expression of microRNAs occurs in patients with inflammatory bowel disease(IBD). Aims:To investigate the expression and significance of microRNA-595( miR-595)in IBD. Methods:A total of 100 patients with IBD at Nanjing General Hospital of Nanjing Military Command of PLA from July 2012 to July 2014 were enrolled,in which 63 cases were ulcerative colitis(UC)and 37 cases were Crohn’s disease(CD). According to disease activity,patients were divided into active UC(aUC)group,remissive UC(rUC)group,active CD(aCD)group and remissive CD(rCD)group. A total of 42 healthy subjects were served as normal control(NC)group. Specimens of serum and intestinal tissue were collected. Expression of miR-595 in serum and intestinal tissue was determined by fluorescence quantitative PCR. Luciferase report gene plasmid containing the 3’UTR of neural cell adhesion molecule 1(NCAM1)or fibroblast growth factor receptor 2(FGFR2)and plasmid containing miR-595 were co-transfected into human colon cancer cell line HCT116 to detect the effect of miR-595 on transcriptional activities of NCAM1 and FGFR2. Results:Expression of miR-595 in serum and intestinal tissue in UC and CD groups was significantly higher than that in NC group(P < 0. 05), and that in aUC and aCD groups was significantly higher than that in rUC and rCD groups,respectively(P < 0. 05). MiR-595 could down-regulate the transcriptional activities of NCAM1 and FGFR2 through directly binding to the 3’UTR of NCAM1 and FGFR2. Conclusions:Expression of miR-595 in serum and intestinal tissue is increased in patients with IBD and correlates with disease activity. MiR-595 inhibits the expressions of tight junction protein NCAM1 and FGFR2,thereby inducing injury of intestinal mucosal barrier and promoting intestinal inflammation. MiR-595 can serve as a serum biomarker for diagnosis of IBD and disease activity evaluation.

OBJECTIVETo observe the effect of activation of aldehyde dehydrogenase 2 (ALDH2) by ethanol on the expression of c-Jun N-terminal kinase (JNK) in the kidney of diabetic rats.

METHODSEightheen healthy male SD rats were randomly divided into 3 groups (n = 6): normal control group, diabetes group and ethanol + diabetes group. After 8 weeks, 24 h urine samples from rats were collected to detect urinary protein content. The kidney was isolated and the ratio of kidney weight/body weight (index of kidney weight) was detected. The levels of fasting blood glucose, glycosylated hemoglobin serum urea nitrogen and serum creatinine were measured. Morphological changes of renal tissue were observed by optical microscope. The protein expressions of ALDH2 and JNK in renal tissue were detected by Western blot.

RESULTSCompared with the normal control rats, the levels of fasting blood glucose, glycosylated hemoglobin, serum urea nitrogen, serum creatinine and the index of kidney weight were increased markedly in diabetic rats. The expression of ALDH2 protein was decreased, while p-JNK, JNK protein expressions and the ratio of p-JNK/JNK were increased. The morphological observation was shown that the amount of glomerular mesangial matrix were increased, basement membrane were thickened and capillary lumen were narrowed. However,in ethanol + diabetes group, renal function was improved and the damage of renal structure was attenuated. The expression of ALDH2 protein was increased, while p-JNK, JNK and the ratio of p-JNK/JNK were decreased.

CONCLUSIONEnhanced ALDH2 expression can protect kidney in diabetic rats, which may be relevant with inhibitting the activity of JNK pathway.

OBJECTIVETo investigate the efficacy and mechanism of Fengshikang (FSK) in treating rheumatoid arthritis (RA).

METHODSThirty-eight patients with RA of damp-heat block syndrome type in Chinese medicine (CM), were randomized into two groups. They all received glucocorticoid therapy for 1 month, but FSK was administered to the 20 patients in the CM group in addition, while to the 18 in the WM group, MTX was given. Besides, a normal control group with 20 healthy subjects was set up. Blood levels of RA related indices were measured and compared.

RESULTSAfter treatment, the levels of rheumatoid factor (RF) and C-reactive protein (CRP) were significantly reduced in both groups (P<0.05), but the reduction was more significant in the CM group (P<0.05). No significant change was found in the level of ESR after treatment and showed no significant difference between groups (P>0.05). Both hGRalpha mRNA and hGRbeta mRNA expressions were significantly higher in the patients than in the normal controls (P<0.01), they were lowered after treatment in the CM group (P<0.01), but significant reduction could only be found in level of hGRbeta mRNA in the control group (P<0.01).

CONCLUSIONFSK combined with glucocorticoid can effectively control the inflammatory reaction, decrease the level of hGRalpha and hGRbeta expressions and enhance the clinical efficacy in treating RA.
