Objective To study the etiology of surgical infection and antibiotic resistance of infective bacteria,so as to provide evidence for clinical treatment.Method The composition and antibiotic resistance in surgical specimens of pathogenic bacteria from January 2008 to December 2010 was analyzed retrospectively.Results A total of 321 pathogens isolated,Gram-negative bacteria 201,accounting for 62.6％,Gram-positive cocci 114,accounting for 35.5％,Fungus 6,accounting for 1.9％.Escherichia coli 116(36.1％),Klebsiella pneumoniae 24(7.5％),Staphylococcus aureus 34(10.6％),Pseudomonas aeruginosa 18(5.6％),Enterococcus faecalis 16(5.0％).Staphylococcus species of Staphylococci methicillinresistant Staphylococcus atureus(MRS),Coagulase-negative staphylococci MRS and ultra wide-spectrum beta-lactamases(ESBLs)detection rate was 52.9％(18/34),83.7％(36/43)and 35.0％(49/140),respectively.The resistance rates of Gram-negative bacilli to piperacillin/tazobactam,ceftazidime,amikacin,imipenem and meropenem were below 20％,Gram-positive cocci,staphylococci to new compound sulfamethoxazole,minocycline,rifampin,vancomycin,teicoplanin and fusidic acid resistance rates were less than 40％,various pathogens had varies resistance.Conclusions Specimens of surgical infection pathogens widely distribute in different drug-resistant bacteria,some strains of multi-drug resistant infection,causing clinical failure of empirical therapy,clinical laboratory susceptibility results should be based on the rational use of antibiotics,to avoid the overuse of antibiotics.

Objective:To investigate the association between anxiety and the change of humoral immune functions and its correlation with HLA-DQB1 polymorphisms.Methods:Total 31 resident doctors were selected randomly and tested by State-Trait Anxiety Inventory(STAI).IgG,IgA,IgM,complement C3 and complement C4 were detected with BECKMAN array360 system;HLA-DQB1*02、*03、*04、*05 and*06 alleles were individually amplified by polymerase chain reaction(PCR)using exon2 group-specific primers.The correlation between immune function and HLA-DQB1 polgmorphisms were investigated.Results:Statistical analysis showed that there was positive correlation with State Anxiety (Ta) and complement C3,either Trait Anxiety (Tc) and complement C3.There was significant difference between HLA-DQB1*02 positive and negative in Ta (P＜0.05),while no difference in complement C3(P＞0.05).There was significant difference between HLA-DQB1*04 positive and negative in Ta and Tc(P＜0.05),while no difference in complement C3(P＞0.05).Conclusion:Anxiety could change some humoral immune functions and this is related with HLA-DQB1 polymorphism.

To establish a new method for the determination of chondroitin sulfate. The method was based on the interaction of sodium chondroitin sulfate with 4-amino-3-hydrazino-5-mercapto-1,2,4-triazole to yield a violet product, 6-mercapto-3-substituted-s-triazolo-\[4,3-b\]-s-tetrzaine derivatives. Absorbance at 540 nm obeyed Beer's Law within the concentration range from 0.1 to 1.0 g?L~(-1)and the results were precise and accurate. The method was operationally simple and had a good precision and sensitivity.

Objective To study CT value in diagnosis and differential diagnosis of submandibular tumor.Methods The CT features of submandibular tumors proved by pathology in 20 cases were analyzed retrospectively and compared with pathologic findings. Double-blind was used to evaluate the value of CT in differentiating both malignant and benign submandibular tumors. Results Of 20 patients,8 were benign tumors, 6 appeared as homogeneous density and well-defined, 2 appeared as inhomogeneous density and partial ill-defined.12 case were malignant of them, 10 were irregular in shape, 8 were heterogeneous indensity, 7 were ill-defined, 5 were well-defined in shape, 4 were homogeneous indensity. Double-blind indicated that 75% submandibular tumors could be qualified by CT, but could not determine the histological type of tumors. Conclusion CT can differentiate most of malignant submandibular tumors from benign tumors, but can not be used to categorize the histological type of tumors.

Objective: To analyze the application value of radionuclide myocardial perfusion imaging in the localization and diagnosis for stable angina pectoris in clinical practice. Methods: A total of 70 patients who had been diagnosed with stable angina pectoris (SAP) were enrolled, and all patients underwent ATP-loaded ATP-99Tcm-MIBI (99Tcm-MIBI) myocardial perfusion imaging (MPI) and coronary angiography (CAG) were used to compare the accuracy of MPI imaging in localization and diagnosis for SAP. Results:In the 70 cases of patients with two methods of examination: ①In MPI diagnosis, positive patients were 50 cases, and the positive predictive value of SAP, sensitivity, negative predictive value and specificity were, respectively, 92.0%, 90.2%, 75.0% and 78.9%. There were 45 patients were consistently diagnosed as SAP by the two methods and the total compliance rate was 90.0%. ②in 70 patients, 51 cases were diagnosed as SAP by CAG examination, the positive rate was 72.9%; ③in 50 MPI positive patients, 46 patients were consistent with the results of CAG diagnosis, and the positive rate was 92.0%. The difference between the two methods was statistically significant (x2= 5.72, P<0.05). Conclusion: 99Tcm-MIBI myocardial perfusion imaging can be used as a gatekeeper in patients with stable angina pectoris, and has high application value in the location and diagnosis for stable angina pectoris. The diagnosis and treatment links of stable angina pectoris can save costs and provide a reliable evidencet for clinical practice.

Objective To investigate the efficacy of intensity-modulated radiation therapy(IMRT)and the prognosis factors in advanced cervical cancer.Methods A total of 218 cases of cervical cancer patients treated in Affiliated Tumor Hospital,Guangxi Medical University,between July 2007 and July 2012,were divided into IMRT group and routine radiotherapy group (conventional group,94 vs 124 cases).To compare the short-term effects of two groups by Chi-square test,and the incidence rate of 1,3,5-year survival by rank sum test ; to compare the acute and chronic toxicity of the two groups by rank sum test.And to analysis prognostic factors by log-rank test and Cox proportional hazard model and multiple linear regression analysis.Results (1) The effective rate in IMRT group was 95.7％ (90/94),which in the conventional group was 86.3％ (107/124; P ＜0.01).The 1,3,5-year overall survival rates in IMRT group were not significant difference than those in conventional group (87.6％ vs 90.1％,73.4％ vs 81.5％,and 72.3 ％ vs 75.7％ ;all P ＞ 0.05).The rate of acute gastrointestinal toxicity was 41.5 ％ (39/94) in IMRT group,vs 42.7％ (53/124) in conventional group(P ＜ 0.01); and the incidence of acute hematopoietic toxicity in IMRT group was 76.6％ (72/94),which was 78.2％ (97/124) in conventional group (P ＜0.01) ; the incidence of acute genitourinary toxicity was 12.8％ (12/94) in IMRT and 8.1％ (10/124) in conventional group(P =0.248).The late gastrointestinal,genitourinary and hematopoietic toxicities were 18.1％ (17/94),16.0％ (15/94) and 25.5％ (24/94),which were lower than those in conventional group 91.9％ (114/124),47.6％ (59/124) and 56.4％ (70/124),respectively (all P ＜0.01).(2) Univariate analysis showed that the International Federation of Gynecology and Obstetrics (FIGO) stage,histological grade and tumor size were closely associated with 5 years disease-free survival rates and overall survival rates (all P ＜ 0.05).Multivariate analysis showed that FIGO stage and histological grade were closely associated with 5 year overall survival rates (all P ＜ 0.01).FIGO stage and histological grade were independent factors to patients' 5-year overall survival rates in cervical cancer (P ＜0.01).Conclusion IMRT would be to reduce the acute and chronic toxicity,and to improve the quality of patients' life,but did not improve the 5 years survival rate in advanced cervical carcinoma.

Objective We discussed the optimal method for intestinal preparation before colonoscopy examination in order to increase the success rate of intestinal examination and reduce the incidence of adverse effect. Methods We divided 120 patients who were to undergo colonoscopy examination into group A, B and C with 40 cases in each group. Group A received oral magensium sulfate 100ml and 6000ml water after that on the morning of the examination. Group B received oral magensium sulfate 50ml and 2000ml in the evening before the examination, oral magensium sulfate 50ml and 400ml water on the morning of the examination. Group C was given oral magensium sulfate 100ml and 4000～5000 water at the same time. Group A and B took part in appropriate activity and were given health education. The effect of intestinal preparation was compared between the three groups. Results The cleaning degree of group B was better than those of the other two groups (P<0.05). The adverse effect of group B was less than that of group C (P<0.01). Conclusions Oral intake of magensium sulfate in the evening before and on the morning of the examination for intestinal preparation could increase the cleaning degree of intestine, facilitate the observation of disease part and lessen adverse effect. It gave satisfying examination results and made patients satisfied.
