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.

Epithelial-mesenchymal transition (EMT) of cancer can enhance the abilities of invasion and metastasis of cancer cells,which is one of the reasons for treatment failure.Peroxisome proliferator-activated receptor gamma (PPARγ) is an important regulatory factor in EMT of cancer cells.Recent researches show that activation of PPARγplays a role in the occurrence and development of EMT by regulating the E-cadherin,Smad complex and body microenvironment.Therefore,in-depth research for the relationship among PPARγ,EMT and cancer is expected to provide a new direction for tumor treatment.

Objective Valve replacement is a conventional therapy for the mitral insufficiency caused by IE. Mitral valve repair as an optional procedure for the disease has become feasible in recent years. However, concerns from surgeons about the recurrence of endocarditis after mitral valve repair remained. in this study we evaluated the long-term clinical outcomes of patients treated with surgery for the mitral insufficiency caused by infective endocarditis (IE). Methods Between July 1990 and July 2007, 83 consecutive patients (male 62, female 21) with mitral valve IE were enrolled in this study. Forty-one (49.4% )patients received mitral valve repair ( MVP,group A) and 42(50. 6% ) patients received mitral valve replacement ( MVR, group B). Thirty-seven cases had concomitant aortic valve replacement; 1 patient had aortic valve repair; 4 cases had ventricular septal defect repair; 1 case had atrial septal defect repair, 12 cases had bicuspid valve repair; 2 cases had coronary artery bypass graft and 1 case had femoral artery thrombus. Intraoperative transesophageal echocardiography were performed in 18 cases for the evaluation of mitral valve regurgitation. Mean cardiopulmonary bypass time, aortic clamping time and postoperative ventilation time were recorded and analyzed. Mid- and long-term clinical and echocardiographic outcomes were assessed.Results Preoperative left ventricular end systolic diameter, left ventricular ejection fraction and the classification of New York Heart Association in group A were significantly lower than those in group B (P ＜ 0. 05), but no difference was observed between the 2 groups in the cardiopulmonary bypass time and the crossclamping time. However, the intubation time and ICU time were shorter in group A than those in group B ( P ＜ 0.05 ). More vegetations were seen in the MVR group than in the MVP group. Three (3.6% ) patients died after the operation in group B. All patients were assessed as in NYHA Ⅰ-Ⅱ at discharge.A follow-up was done between 1 to 165 months (mean 39 months) with a mean follow-up rate of 95%. In the MVR group, peri-valvular leakage happened in 1 case, cerebral hemorrhage happened in 2 cases and repetitive pleura! effusion in 1 case. One death happened in the MVR group and none in the MVP group. The 10-year survival rate (100% ) in group A was nonsignificantly higher in group A than that (75% ) in group B(P =0.081). Conclusion Mitral valve repair is feasible for treating mitral valve lesions caused by endocarditis, and may provide an optimistic long-term outcome to the patients. The indication for mitral valve repair is mild to moderate mitral valve lesion. Experienced cardiac surgeons, use of antibiotics before and after the operations based on drug-sensitivity test and blood test, as well as follow-up the patients yearly, are important factors for the favorite outcomes.

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.
