Objective To explore the clinical process and prognosis of middle and intermediate uveitis in children and adults.Methods A total of 121 patients with intermediate uveitis admitted to our hospital from January 2012 to December 2014 were enrolled in the study.Among them,there were 67 cases with monocular involvement and 54 cases with binocular involvement;59 cases were children and 62 cases were adults.All subjects were treated with personalized regimen according to the severity of the disease.The treatment effects and prognosis were compared between patients with different ocular involvement,children and adults.Results The total effective rate of treatment in patients with monocular involvement,children,patients with binocular involvement and adults were 92.5％,93.2％,92.6％ and 91.9％,respectively (all P ＞ 0.05).There was no significant difference in acute phase protein and visual acuity between the patients with ocular involvement and children,adults before treatment (all P ＞ 0.05),and there was no significant difference in the indexes between two groups after treatment (all P ＞ 0.05).The acute phase protein in each group after treatment was decreased,and the visual acuity was obviously increased,there were statistical differences before and after treatment (all P ＜ 0.05).Conclusion Individualized treatment regimen for patients with intermediate uveitis can improve the therapeutic effect,control inflammation and improve visual acuity.The curative effect is not significantly related to age and degree of ocular involvement.

The preliminary results of inactivation of model parvovirus M13Mp 18 in plasma by long-waveUVA irradiation combined with psoralen derivatives were described.At 8-MOP concetration of300?g/ml plasma and UVA intensity of 11.5mW/cm~2,the UVA irradiation for 30～120 min couldresult in virus inactivation of 10~(5～9) infectious dose/ml.Quenchers were used to reduce the damage ofUVA to proteins in order to improve the clotting factor recovery after irradiation.2mmol/Lglutathione,or 2mmol/L glutathione with 2 mmol/L mannitol could significantly improve the Frecovery after irradiation.

Objective To investigate the effect of melatonin on serum malondialdehyde (MDA), NF-κB, tumor necrosis factor-α(TNF-α) andβ2-microglobulin (β2-MG) levels in secondary brain damage following intracerebral hemorrhage patients.Methods 90 patients secondary brain damage following intracerebral hemorrhage were divided into experimental group and control group, 45 cases in each group.The control group were given conventional treatment after surgical removal of hematoma, and the experimental group, on the basis of control group, were given melatonin capsule (6 mg melatonin) , orally, once a day, for 2 weeks treatment.The levels of MDA, NF-κB, TNF-αand β2-MG in patients’ serum were detected.Results The MDA, NF-κB, TNF-αand β2-MG levels after treatment significantly decreased compared with before treatment in two groups (all P<0.05), and the above indexes in experimental group significantly decreased compared with control group ( P <0.05 ).Conclusion Melatonin can significantly reduce the levels of MDA, NF-κB, TNF-αand β2-MG levels in brain injury patients with cerebral hemorrhage, and repair brain damage, which has a guiding significance for clinical use.

Objective To investigate the effect of different composed combination of EGCG and cisplatin on human colon adenocarcinoma cell line SW620 and the related mechanisms. Methods SW620 cells at exponential phase were treated with cisplatin(5 mmol.L-1)and EGCG(0, 25, 50 and 100 mmol.L-1).Seventy hours after the cultivation, cell proliferation was detected with MTT;the percentage of apoptotic cells was determined by flow cytometry;expression levels of JAK2, p-JAK2, p-STAT3, STAT3, Bax, Bcl-2, cleavage-PARP, and cleavage-caspase3 were detected by Western blotting. Results The SW620 cell proliferation rate was(95±5)%,(67±5)%,(42±5)%(22±4)% and the apoptotic rat was 5%, 15%, 35%, 57%in the 0, 25,50, 100 mmol.L-1 EGCG groups, respectively.Moreover, EGCG up-regulated the expression of Bax, cleavage-PARP and cleavage-caspase3(P<0.05)and down-regulated the expression of p-JAK2, p-STAT3 and Bcl-2(P<0.05)in a dose-dependent manner, but had no influence on the expression of JAK2 and STAT3(P>0.05). Conclusion EGCG can promote cisplatin-induced apoptosis and proliferation inhibition of human colon adenocarcinoma cell lines of SW620 by suppressing JAK2/STAT3 gignaling pathway.

Background:14 C-urea breath test(14 C-UBT)is widely used for diagnosis of Helicobacter pylori(Hp)infection owing to its noninvasiveness and high sensitivity and specificity. Nevertheless,the presence of false-negative result can influence the diagnostic accuracy. Aims:To investigate the possible causes of false-negative 14 C-UBT for improving the accuracy of diagnosis. Methods:Eight-two cases with confirmed false-negative 14 C-UBT and 813 controls with true-positive 14 C-UBT at the People’s Hospital of Xinjiang Uygur Autonomous Region from Jan. 2014 to Aug. 2014 were enrolled. Patients in both groups were diagnosed as positive for Hp infection by Warthin-Starry silver staining combined with Hp stool antigen test. Univariate and multivariate analysis were performed to screen the factors related with false-negative 14 C-UBT. Results:In univariate analysis,5 variables were significantly different between case group and control group(P ﹤ 0. 05),and were taken into the multivariate analysis. Logistic stepwise regression analysis revealed that bile reflux( OR = 3. 961,P ﹤0. 001),post subtotal gastrectomy(OR = 9. 734,P ﹤ 0. 001),type Ⅱ Hp infection(OR = 1. 892,P = 0. 012)and upper gastrointestinal bleeding( OR = 4. 979,P ﹤ 0. 001 ) were the independent risk factors for false-negative 14 C-UBT. Conclusions:Bile reflux,upper gastrointestinal bleeding,post subtotal gastrectomy and type Ⅱ Hp infection might be the influential factors for false-negative 14 C-UBT. Combined tests for Hp infection should be suggested in patients with negative 14 C-UBT who had undergone subtotal gastrectomy or complicated with bile reflux or upper gastrointestinal bleeding.

Objective To explore the correlation between Helicobacter pylori (H.pylori) infection and colorectal cancer.Methods From January 2008 to January 2014,263 patients pathologically diagnosed as colorectal cancer were selected as colorectal cancer group,and at the same period 263 patients with normal colon mucosa under colonoscopy were set as control group.The rates of H.pylori infection,the rates of H.pylori infection in patients with different pathological types of colorectal cancer,the rates of H.pylori infection accompanied with atrophic gastritis and the rates of H.pylori infection accompanied with intestinal metaplasia of two groups were retrospectively analyzed.The difference of H.pylori infection between proximal colorectal cancer and distal colorectal cancer was compared.Chi-square test was performed for comparison and odds ratio (OR) value and 95％ confidence interval (CI) were calculated.Results Among 263 patients with colorectal cancer,the H.pylori infection rate of colorectal cancer group was 63.50％ (167/263),which was higher than that of control group (39.54％,104/263),and the difference was statistically significant (x2 =27.66,OR=2.66,95％ CI 1.85 to 3.83,P＜0.01).There was no statistical difference in rates of H.pylori infection among different pathological types of colorectal cancer (x2=0.15,P=0.93).The rate of H.pylori infection accompanied with atrophic gastritis in patients with colorectal cancer was 46.39％ (122/263) which was higher than that of control group (23.57％,62/263),and the difference was statistically significant (x2=28.53,OR=2.94,95％CI 1.98 to 4.36,P＜0.01).The rates of H.pylori infection accompanied with intestinal metaplasia in patients with colorectal cancer was 17.87％ (47/263) which was higher than that of control group (4.18％,11/263),and the difference was statistically significant (x2=23.56,OR=5.50,95％CI 2.76 to 10.95,P＜0.01).There was no significant difference in the rate of H.pylori infection between the proximal colorectal cancer and the distal colorectal cancer (x2 =1.48,P =0.22).Conclusion H.pylori infection,together with atrophic gastritis and intestinal metaplasia caused by it are correlated with colorectal cancer.

Early gastric cancer is the gastric cancer limited to mucosa or submucosa no matter there is lymph node metastasis or not,and its prognosis is relatively good. China is the high morbidity area of gastric cancer,most patients with gastric cancer are diagnosed at an advanced stage losing the chance of operation and the survival rate is low. Therefore, early diagnosis and treatment is crucial for improving the survival rate of patients with gastric cancer. This article reviewed the progress in study on diagnosis of early gastric cancer from the following aspects:serology,imaging,endoscopy and genetics.

Objective To study the effect of caveolin-1 on renal injury and the expression of tight junction proteins in MRL/lpr mice kidney.Methods The mice were divided into 4 groups:5 mice in the normal control group (BALB/c mice);the MRL/lpr lupus mice (n=18) were randomly divided into the MRL/lpr group in which 6 mice were included;the negative control group in which 6 mice were included;the caveolin1 transfection group in which 6 mice were included.The changes of urine protein,the levels of urea (BUN) and creatinine (Cr) were detected.The expressions of claudin-5,occludin,ZO-1 and caveolin-1 protein were determined by western bloting.Analysis of variance was used to determine statistical significant differences between the two groups.A significance level of 0.05 was considered as signigicant.Results Compared with the control group,24 h urine protein [(2 894±437) mg,(412±72) mg],BUN [(8.7±1.5) mmol/L,(6.9±0.4) mmol/L],Cr [(106±22) μmol/L,(85±4) μmol/L] were significantly increased,level of caveolin-1 protein increased (265±17,61±6),the level of occludin (114±12,190±12),claudin-5 (60±5,80±6) and ZO-1 (98±11,206±15) protein decreased in the MRL/lpr group (P＜0.05).After caveolin-1 transfection,the levels of urinary protein [(1 253±249) mg,(2 894±437) mg],BUN [(6.5±1.3) mmol/L,(8.7±1.5) mmol/L],Cr [(78±17) μmol/L,(106±22)μmol/L] were significantly decreased,and the levels of occludin (218±16,114±12),claudin-5 (87±6,60±5)ZO-1 (313±17,98±11) were increased (P＜0.05).Conclusion The expression of caveolin-1 protein in the renal tissues of lupus nephritis increases.Caveolin-1 can reduce the expression of tight junction proteins and contribute to progres-sion of lupus nephritis.
