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.

AIM:To investigate the inhibitory effects of recombinant human Mullerian inhibiting substance on cell proliferation in human ovarian carcinoma cells (OVCAR8 and SKOV3 cell lines). METHODS:The expression of MISIIR protein and the localization of MISIIR protein were analyzed by Western blotting and confocal spectral microscopy,respectively. Cell apoptosis and cell cycle were detected by flow cytometry (FCM). Cell viability was determined via MTT method. Clone formation test was used to detect oncogenicity in vitro.RESULTS:The MISIIR protein expression in OVCAR8 cells but not in SKOV3 cells was observed. MISIIR expression was seen on the OVCAR8 cell surface and in the cytoplasm with both antibodies. After treated with rhMIS for 48 h,the cell viability was significantly decreased in OVCAR8 cells. rhMIS inhibited the oncogenicity of OVCAR8 cells greatly. The cell apoptosis of OVCAR8 cell exposed to 10 mg/L rhMIS was (31.3±2.1)%,and OVCAR8 cells in the G_1 phase were increased by (70.4±3.0)%. Compared to SKOV3 cells the differences were significant (P<0.01). CONCLUSION:Recombinant human Mullerian inhibiting substance suppresses the growth of MISIIR-positive ovarian cancer cells by inducing apoptosis and cell cycle arrest. We predict that rhMIS might be a new target to treat human ovarian malignancies.

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.

Diabetes mellitus increases the risk of breast cancer and affects the prognosis of breast cancer patients. Metformin, an anti-diabetic drug, decreases blood glucose level and has a role in suppressing various cancers. In addition, metformin has a unique in-hibitory effect on breast cancer, i.e., it can inhibit breast cancer cells in vivo and in vitro. Moreover, metformin exerts its anti-tumor ef-fect on epidermal growth factor receptor 2 (HER-2) positive and monoclonal antibody trastuzumab-resistant breast cancer cell lines, breast cancer stem cells, and triple negative breast cancer cells. Metformin can reduce the risk of the breast cancer in patients with dia-betes, lower histologic grade, and increase expression of estrogen and progesterone receptors. Furthermore, metformin has certain effect on neo-adjuvant chemotherapy for breast cancer. This review aims to clarify the mechanism of metformin in restraining breast cancer based on basic and clinical study results.

Objective To investigate the correlation between serum lipoprotein (a) (Lp(a)) level andischemic stroke and its etiological subtypes. Methods The consecutive inpatients with acute ischemic stroke (case group) and age-and sex-matched healthy subjects (control group) over the same period were enrolled retrospectively. The demographic and baseline clinical data, as well as fasting blood glucose, fibrinogen,homocysteine, total cholesterol, triacylglycerol, high-densitylipoprotein cholesterol, low -density lipoprotein cholesterol, and Lp(a) concentration of the case group and the control group were collected. According to TOAST classification criteria, the patients in the case group were divided into large artery atherosclerosis (LAA), small artery occlusion (SAO) and cardioembolism (CE), and the patients with other determined etiology and undetermined etiology were excluded. Multivariate logistic regression analysis was used to make clear the correlation between serum Lp(a) and acute ischemic stroke and its etiological subtypes. Results A total of 214 patients with ischemic stroke were enrolled. Ninety-seven had LAA (45.33%), 64 (29.91%) had SAO, and 53 (24.77%) had CE. There were 118 subjects in the control group. There were significant differences in the proportions of hypertension, diabetes, hyperlipidemia, atrial fibrillation and alcohol consumption, as well as systolic blood pressure, diastolic blood pressure, fasting blood glucose, total cholesterol, low -density lipoprotein cholesterol, Lp(a), fibrinogen, and homocysteine between the case group and the control group (all P <0.001). Multivariate logistic regression analysis showed that after adjustment for age and sex, Lp(a) is an independent risk factor for ischemic stroke (odds ratio [OR] 2.014, 95% confidence interval [CI ] 1.273-3.092, P = 0.036). The independent risk factors for LAA included hypertension (OR 3.353, 95% CI 1.714-6.558, P = 0.001), systolic blood pressure ( OR 2.786, 95% CI 1.136-5.538, P =0.016), homocysteine ( OR 1.108, 95% CI 1.031-2.191, P = 0.005), total cholesterol (OR 2.169, 95% CI 1.599-4.943, P = 0.001), low -density lipoprotein cholesterol ( OR2.782, 95% CI 1.093-5.238, P =0.024), and Lp(a) (OR 3.072, 95% CI 1.907-8.064, P =0.001). Theindependent risk factors for SAO included hypertension ( OR 7.042, 95% CI 3.189-25.55, P =0.001), diabetes mellitus (OR 5.162, 95% CI 2.372-11.23, P =0.001), fibrinogen (OR 1.667, 95% CI 1.434-2.025, P = 0.045), and homocysteine (OR 1.967, 95% CI 1.859-1.995, P =0.036). The independent risk factors for CE included atrial fibrillation (OR 13.340, 95% CI 4.637-39.20, P = 0.001), fibrinogen (OR 2.365, 95% CI 1.147- 4.904, P =0.029), and Lp(a) (OR 1.656, 95% CI 1.996-3.001, P = 0.035). Conclusions Lp(a) is an independent risk factor for ischemic stroke, and can be used as a serum biomarker for predicting the risk of the onset of ischemic stroke. There are differences in independent risk factors between the different stroke etiological subtypes. Lp(a) is independently associated with LAA and CE; however, it has no independent correlation with SAO.
