ObjectiveTo survey the usage of prophylactic antimicrobial agents in type Ⅰ incision surgical operation.MethodsThe data of medication of 140 patients with type Ⅰ incision operation including thyroid surgery,breast surgery and repairing hernia surgery were investigated and statistically analyzed.ResultsThe preventative antibiotics usage in type Ⅰ incision operations was 100％.The frequency ranking of the perioperative antibiotics application was cephamycins ( 116 cases),cephalosporins ( 18 cases) and aminoglycosides ( 8 cases ).127 patients received antibacterials before operation.The total time for medication at least 1 day,up to 4 days.The antibacterials used in single kind and two kinds were 136 cases and 4 cases.ConclusionThe prophylactic use of antimicrobials in patients undergoing type Ⅰ incision operations in this hospital was irrational in the rate of antimicrobials use,choice of drug categories and medication duration,etc.Antibiotic prophylaxis in type Ⅰ incision perioperative should be further strengthened to supervise and management so as to promote rational use.

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.

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 study the effect of hydroxychloroquine (HCQ) on the suppressors of cytokine signaling (SOCS) in the kidney of MRL/lpr mice and evaluate the protection of HCQ on lupus nephritis.Methods Twenty-six rats were randomly divided into 3 groups:the control group which was consisted of 6 mice; the MRL/lpr group which was consisted of 10 mice; and the HCQ group which was consisted of 10.24-hour urinary protein level and anti dsDNA levels were tested.The expressions of SOCS-1 and SOCS-3 protein were determined by western blot.Analysis of variance was used to determine statistically significant differences between the two groups.A P value less than 0.05 was considered to be statistically significant.Results Compared with the control group,the levels of 24-hour urinary protein [(2 356.6±509.3) mg vs (440.3±90.1)mg] and anti ds-DNA (128.7±32.3 vs 14.9±1.4) were significantly increased in the MRL/lpr group,the expression levels of SOCS-1 and SOCS-3 protein were increased.After treated with HCQ,the levels of 24-hour urinary protein [(70.8±11.1) mg vs (2 356.6±509.3) mg] and anti-dsDNA (111.8±330.1 vs 128.7±32.3)were significantly decreased,the expression level of SOCS-1 and SOCS-3 protein decreased significantly (P＜ 0.05).Conclusion HCQ can inhibit SOCS expression in the kidney of lupus mice,reduce proteinuria and delay progression of immune disorders and lupus nephritis.

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.

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.
