0.05). TNF-? in group EK and EKM was lower than that in group E (P0.05). Conclusions Ketamine can inhibit the release of TNF-? caused by LPS and increase myocardial cAMP level, protecting myocardium from sepsis. This may be one of the anti-septic shock mechanisms of ketamine. Combination of midazolam with ketamine does not affect the anti-septic shock property of ketamine.

Objective To systematically review the efficiency of 18 F-FDG PET in glioma grading by using Meta-analysis. Methods Retrieval in PubMed and China National Knowledge Infrastructure (CNKI)was performed. Relevant papers concerning with glioma diagnoses with 18 F- FDG PET were selected. Paper quality was evaluated according to the standard of diagnostic test recommended by Cochrane Workshop. The data of glioma malignancy degree defined as semi-quantitatively and qualitatively were extracted from the papers. Meta-analysis was conducted with the Meta-Disc software to calculate pooled weighted sensitivity and specificity with 95% confidence interval (CI). Summary receiver operating characteristic (SROC) curve was performed and the areas under the curve (AUC) were calculated. Results Seven hundred and fifty-three patients from 17 papers ( 16 in English, 1 in Chinese) were included. Two hundred and seventy-two patients from 11 papers were using semi-quantitative (tumor to cortex ratio, T/C; tumor to white matter ratio,T/W) method and 481 patients from 9 papers were using qualitative method (visual observation, some of the papers had 2 or more methods). After heterogeneity test was done, different effect models were selected. The pooled weighted sensitivity, specificity and diagnostic odds ratio (DOR) with 95% CI for T/C group was 0. 952 (95% CI: 0. 903 -0. 980), 0. 409 (95% CI: 0. 318-0. 504) and 11. 746 (95% CI:5. 368-25. 702) respectively. The pooled weighted sensitivity, specificity and DOR with 95% CI for T/W group was 0. 857 (95% CI: 0. 768-0. 922), 0. 538 (95% CI: 0. 431 -0. 642) and 22. 066 (95% CI:7. 077-68. 800) respectively. The pooled weighted sensitivity, specificity and diagnostic odds ratio (DOR)with 95% CI for qualitative method was 0.810 (95%CI: 0.757-0.855), 0.870 (95%CI: 0. 819-0.911 ) and 15.282 (95% CI: 3. 716-62. 851 ) respectively. The AUC for T/C group, T/W group and qualitative method was 0.8604, 0. 8373 and 0. 8724 respectively. Conclusions Grading glioma by 18 F-FDG PET with semi-quantitative method may provide high diagnostic sensitivity. If qualitative method is used, the diagnostic specificity may be higher.

Objective To investigate the effect of MDR1 and MDR3 gene silence by shRNA of human breast carcinoma cell line MCF-7/Adr,and explore the role of MDR1 and MDR3 in adriamycin-resistance of breast carcinoma cells. Methods shRNA plasmid vector specifically targeting MDR1 and MDR3 gene was transfected into cells. The control group was transfected with empty vector. The concentration of adriamycin was detected by the flow cytometry (FCM). Cell apoptosis was analysed by FITC-Annexin-V/PI double staining. Cell viability and the IC50 of adriamycin on MCF-7/Adr cells were determined by MTT method. MDR1 and MDR3 mRNA were assessed by RT-PCR. P-gp expression was detectedby immunochemistry. Results After treatment with ABCB1 and ABCB4 shRNA plasmid vector, the apoptosis of MCF-7/Adr cells was (30.21±1.65)%and (22.07±2.17)% respectively. Compared with untransfecedgroup and empty vector transfection group the difference was significant(P＜0.01). MDR1 and MDR3 shRNAcould increase cellular adriamycin accumulation of MCF-7/Adr cells. MCF-7/Adr cells viability and the IC50were significantly decreased after transfection. Compared with untransfeced group and empty vector transfectiongroup, the mRNA level of MDR1 and MDR3 in MCF-7/Adr cells were decreased by (89.5±0.8)%and(85.1±1.2)%, the reduction of MDR1 and MDR3 mRNA was in a time-dependent manner. Immunochemistry proved that the expression of p-gp was significantly inhibited. Compared with untransfeced group and empty vector transfection group the difference was significant (P＜0.05). Conclusion The shRNA can effectively and specifically silence the expression of MDR1 and MDR3 gene, reverse the adriamycin-resistance mediated by P-gp in MCF-7/Adr cells. The reversal effect of adriamycin-resistance by shRNA of MDR1 is more effective than that of MDR3.

AIM: To explore the clinical effects of high frequency electrical capsulotomy in maturation period cataract surgery.
●METHODS: A total of 68 cases of maturation period cataract were selected and underwent the surgery of continuous circular capsulorhexis using the high frequency electrical capsulotomy.
●RESULTS: The success rate was 91% in 68 cases with the high frequency electrical capsulotomy.
● CONCLUSION: The high frequency electrical capsulotomy in maturation period cataract surgery has significant advantages and brilliant clinical values.

Objective To discuss the informatization of multi hospitals. Methods Considering about the current situation of in‐formation construction to the First Affiliated Hospital of Chongqing Medical University, a set of solution was put forward based on the all in one card together with the two level information platform. Results Initial trials proved the feasibility of the solution. Con‐clusion The informatization of the multi hospitals contributes a lot to the source sharing between the regional hospitals, the im‐provement of hospital management and a better medical service.

Objective To explore the effect of different doses of tirofiban for PCI, myocardial injury and arterial flow conditions.Methods 70 patients undergoing PCI elevation acute myocardial infarction, were randomly and equally divided into the observation group and the control group.The control group of patients before PCI given haplotype character loading dose of tirofiban, the observation group were given a double load before PCI tirofiban.Recording and analyzing two groups of patients cTnI (cardiac troponin I), 90 minST section down percentage circumstances.Results The patients after 6h, 12h, 24hcTnI contents were (2.11 ±0.50,3.50 ±1.64,3.28 ±1.15) ng/mL was significantly lower than the control group (4.09 ± 1.13,9.48 ±2.61,5.79 ±1.26) ng/mL, and the difference was significant(P<0.05); the observation group were CTFC, 90 min fall within ST respectively was significantly better than the control group ( P<0.05 ) .Conclusion Preoperative use of double loading dose of tirofiban can effectively improve the blood flow after PCI,, and reduce the incidence of myocardial injury and postoperative cardiovascular events.

Conventional diagnostic methods used for pathologic nipple discharge (PND) include color ultrasound, mammary mo-lybdenum target X-ray radiography (mammography), nipple cytologic smears, and ductography. Diagnosis of PND through inspection yields indirect signs and has low positive rate. Fiberoptic ductoscopy (FDS) allows direct visualization of intra-ductal lesions, evaluates etiology of PND, and accurately locates intraductal lesions through wire marking. FDS is a valuable test for the early diagnosis of breast cancer and can help identify appropriate location for surgical excision. Interventional treatment for ductal ectasia and inflamma-tion is also efficient. Our study discusses FDS as a novel diagnosis and treatment method for PND patients.
