Objective To study the value and effectiveness of surgical management and mapping in supratentorial tumoral complicated with epilepsy and to study the correlations between tumor and the epileptogenic focus.Methods The clinical data of 121 patients with supratentorial cerebral tumor but epilepsy as initial symptom were retrospectively analyzed for the incidence of pre-and postoperative epileptic seizures,including grade Ⅰ glioma in 1 5 cases and grade Ⅱ glioma in 35 cases,grade Ⅲ-Ⅳglioma in 12 cases,menigoma in 32 cases,metastases in 10 cases,cavernous angiomas in 15 cases,and ependymomas in 2 cases.Results Surgery based on CT/MRI,seizure type and EEG changes was conducted.There was no death in operation.The highest incidence was in frontal lobe and the lowest in occipital lobe.Correlations between localization of tumor and the epileptogenic focus:there were 50 cases in the same location,near or beside tumors in 28 cases,far separate apart(＞2 cm)from tumors in 25 cases,no relationship was found in 18 cases.103 patients were followed up for one to nine years.31 patients had a few seizures in the early postoperative period.Epileptic seizures were cured without anti-epilepsy drugs in 83 cases.Conclusion There are some differences between tumors'location and epileptogenic focus in supratentorial tumoral epilepsy.The location and size of epileptogenic zone should be detected before and during operation.The resection of the tumor combined with the resection of the epileptogenic zone"epilepsy surgery"can provide good results.

The aim of the study is to establish a new method of quality evaluation and validate its feasibilities by the simultaneous quantitative assay of four lignanoids in Schisandra chinensis. A new quality evaluation method, quantitative analysis of multi-components by single marker (QAMS), was established and validated with Schisandra chinensis. Four main lignanoids, schisandrin, schisantherin A, deoxyschizandrin and gamma-schizandrin, were selected as analytes and schisandrin as internal reference substance to evaluate the quality. Their contents in 13 different batches of samples, collected from different bathes, were determined by both external standard method and QAMS. The method was evaluated by comparison of the quantitative results between external standard method and QAMS. No significant differences were found in the quantitative results of four lignanoids in 13 batches of S. chinensis determined by external standard method and QAMS. QAMS is feasible for determination of four lignanoids simultaneously when some authentic standard substances were unavailable, and the developed method can be used for quality control of S. chinensis.

The complex field cure instrument is a new medical instrument with which an experiment was carried out. Rats were continuously irradiated by the complex field for 90 days, with a day's total dose of 285.9 M.T.G. while other rats weren't irradiated for control group. The animals were respectively killed at 7d, 14d, 30d, 60d and 90d, and their blood samples were taken for cell and humoral immune analysis. The results show that values of lymphocyte transform rate, soluble receptor (SIL-2R), total hemolytic complement levels (CH50) and immunoglobulin (A.G.) after irradiation are more than those of the control group having proved that the instrument may improve immune function of rats.

OBJECTIVETo explore the impact of ideal health behaviors and health factors on the detection rate of the carotid plaques.

METHODSSubjects with previous stroke, TIA, myocardial infarction were excluded from the study. A total of 5852 employees (active and retired employers from Tangshan Kailuan company) aged 40 years and over were included through stratified random sampling. Information was obtained from the unified questionnaire, measurements of blood biochemistry and carotid artery ultrasonography.

RESULTS(1) The carotid artery plaque detection rates were 67.0%, 52.3%, 50.5%, 44.3%, 37.2%, 31.9%, 26.1% and 4.2% in the groups with 0, 1, 2, 3, 4, 5, 6 and 7 components of ideal cardiovascular health behaviors and health factors, respectively. (2) The carotid artery plaques total burden score [TBS: M (Q1, Q3)] were 7(7,7), 7(5,7), 7(5,7), 5(3,5), 5(3,5), 5(3,5), 3(3,3), 3(3,3) in the groups with 0, 1, 2, 3, 4, 5, 6 and 7 components of ideal cardiovascular health behaviors and health factors, respectively. (3) Multiple logistic regression analysis showed that 3, 4, 5 and greater than 5 components of ideal cardiovascular health behaviors and health factors were protective factors against carotid plaques compared to less than 2 components of ideal cardiovascular health behaviors and factors (all P < 0.05), the OR (95%CI) values were 0.78 (0.62 - 0.98), 0.53(0.62 - 0.98), 0.52 (0.39 - 0.71) and 0.40 (0.25 - 0.64), respectively.

CONCLUSIONIncreasing ideal cardiovascular health behaviors and factors are negatively linked with the detection rate and TBS of the carotid plaques.

OBJECTIVETo investigate the abnormal expression of interferon-induced transmembrane protein 3 (IFITM3) in hepatocellular carcinoma (HCC) and the effect of IFITM3 knock-down on the biological behaviors of hepatocellular carcinoma HepG2 cells.

METHODSWestern blot analysis and immunohistochemical staining were used to determine the expression of IFITM3 protein in 60 HCC samples and paired adjacent tissues. A small interfering RNA fragments of IFITM3 (IFITM3 siRNA) was transiently transfected into HepG2 cells and expressions of IFITM3 at mRNA and protein levels were examined by qRT-PCR and Western blotting. The changes in the proliferation of the transfected cells were determined using cell counting kit 8 (CCK8) assay, and the cell invasion and migration were tested using Transwell assay and wound-healing assay.

RESULTSCompared with the adjacent tissues, HCC tissues expressed significantly higher levels of IFITM3. In HepG2 cells, transfection with IFITM3 siRNA resulted in significant down-regulation of IFITM3 expression at both the protein and mRNA levels and obviously suppressed cell proliferation, invasion, and migration ability as compared with the cells transfected with scrambled siRNA and control cells (P<0.05).

CONCLUSIONSIFITM3, which is overexpressed in HCC, plays a vital role in the proliferation and invasion of HCC cells and may serve as a potential target for gene therapy of HCC.

OBJECTIVEThis study aimed to investigate the effects of gene polymorphism of heat shock protein 70-2 (HSP 70-2) 1267A/G on the mRNA level HSP 70-2 mRNA and the protein level HSP 70 in human lung cancer.

METHODSForty six lung cancer patients diagnosed histopathologically between February and August 2008 from a hospital in zhengzhou were enrolled as the subjects in this study. Gene polymorphism of HSP 70-2 1276A/G in 46 patients with lung cancer was detected by PCR-RFLP. The mRNA levels of HSP 70-2 mRNA and the protein levels of HSP 70 in lung tissue and para-cancerous tissues of these subjects were determined by RT-PCR and Western blotting respectively.

RESULTSThe expression levels of HSP 70-2 mRNA (1.02 ± 0.30) and HSP 70 protein (0.44 ± 0.12) in the lung cancer tissues was significantly higher than that in para-cancerous tissues (0.19 ± 0.04, 0.12 ± 0.02). The relative levels of HSP 70-2 mRNA in the subjects with AA genotype (1.32 ± 0.22) were significantly higher than the patients with AG genotype or GG genotype (0.95 ± 0.17, 0.70 ± 0.16) at the site of 1267 (A/G) (P < 0.01); however, the relative protein levels of HSP 70 were 0.47 ± 0.13 (AA genotype), 0.42 ± 0.11 (AG genotype), 0.45 ± 0.11 (GG genotype), respectively, which showed no statistically significant difference (P > 0.05).

CONCLUSIONThe polymorphism of HSP 70-2 1267 (A/G) is highly associated with the transcription level of HSP 70-2 mRNA, but not with the expression level of HSP 70 protein.

OBJECTIVETo explore the different effects of systolic blood pressure (SBP) and low density lipoprotein on carotid plaques (LDL-C).

METHODSA total of 101 510 serving and retired workers of a company who participated in the health examination in 2006-2009, 5852 participants were selected as study subjects by stratified random sampling according to the age and sex ratio. These subjects took their health examination in 2010-2011 including the carotid ultrasound. Finally, 5361 eligible participants with complete data were included in the analysis. The detection and weighted rates of carotid plaques were calculated for four groups: normal SBP and LDL-C group (3524 subjects), normal SBP and high LDL-C group (356 subjects), elevated SBP and normal LDL-C group (1308 subjects) and elevated SBP and high LDL-C group (173 subjects). The effects of different baseline SBP and LDL-C on detection rates of the carotid artery plaques were analyzed by logistic regression.

RESULTSThe detection rate of carotid plaques in normal SBP and LDL-C group, normal SBP and high LDL-C group, elevated SBP and normal LDL-C group, elevated SBP and high LDL-C group was 33.7% (1186/3524), 41.3% (147/356), 64.8% (847/1308), 68.8% (119/173) (χ(2) = 425.75, P < 0.05) and the weighted detection rate was 36.0%, 42.0%, 64.5% and 68.3% respectively. For men, the detection rate was 44.2% (877/1985), 51.1% (97/190), 70.6% (657/930), 71.3% (82/115) (χ(2) = 194.02, P < 0.05) and the weighted detection rate was 31.2%, 36.1%, 49.8% and 50.3% respectively. For women, the detection rate was 20.1% (309/1539), 30.1% (50/166), 50.3% (190/378), 63.8% (37/58) (χ(2) = 180.17, P < 0.05) and the weighted detection rate was 30.9%, 46.3%, 70.3%, and 88.1% respectively. After adjusted for other risk factors, the OR (95%CI) value was 1.37 (1.05 - 1.78), 2.05 (1.74 - 2.43) and 2.12 (1.45 - 3.12) for normal SBP and high LDL-C group, elevated SBP and normal LDL-C group and elevated SBP and high LDL-C group respectively compared with normal SBP and LDL-C group.

CONCLUSIONElevated SBP and high LDL-C were risk factors of the carotid artery plaques. Compared with high LDL-C, elevated SBP may add a higher risk for carotid plaques.

OBJECTIVETo explore the association between blood pressure level and incidence of carotid arterial plaque in middle-aged and elderly people.

METHODSA total of 5852 individuals were randomly stratified from the 101 510 health examination survey participants in Tangshan Kailuan Company community during 2006-2007. A total of 5440 people (age above 40 years old, free of stroke, TIA and myocardial infarction) were enrolled in the final analysis. A questionnaire survey, blood biochemical analysis and carotid artery ultrasound examination were finished by trained medical staff. Sixteen individuals without carotid artery plaques information and 35 individuals without blood pressure information were excluded. Finally, a total of 5389 participants [3235 male, mean age: (54.7 ± 11.8) years] were analyzed. According to 2010 Chinese guideline to prevention and treatment of hypertension and blood pressure level classification, participants were divided into normotensive group (n = 1377), high normal blood pressure group (n = 1971) and hypertensive group (n = 2041). Multivariate logistic regression analysis was used to determine the risk factors of the carotid artery plaques.

RESULTSAge, male gender, BMI, IMT, TG, FBG, smoking and alcohol drinking rate were significantly higher in high normal blood pressure group than in normotensive group (all P < 0.05), LDL-C, HDL-C, hs-CRP and TC were similar between these two groups. Incidence of carotid artery plaques in normotensive, high normal blood pressure and hypertensive groups was 24.8%, 37.4%, 60.2% respectively. The risk of carotid artery plaques was increased to 38% and 163% in high normal and hypertensive groups compared to normotensive group, the OR ratio was 1.38 (95%CI: 1.15-1.66) and 2.63 (95%CI: 2.18-3.18), respectively. After adjusting gender, age, smoking, alcohol consumption, TG, TC, HDL-C, FBG, hs-CRP and BMI, the risk of developing carotid artery plague was increased in proportion to increasing blood pressure and the OR value was 1.24 (95%CI:1.01-1.52) , 1.69 (95%CI:1.34-2.15) and 2.66 (95%CI:2.20-3.21) in high normal group I [SBP/DBP 121-129/80-84 mm Hg(1 mm Hg = 0.133 kPa)] and high normal group II (SBP/DBP 130-139/85-89 mm Hg) and hypertensive group, respectively.

CONCLUSIONSThe cardiovascular risk factors and prevalence of carotid artery plague increase in proportion to blood pressure level in this cohort. The detection rate of carotid artery plague is already significantly increased in individuals with high normal blood pressure.

OBJECTIVEThis study was conducted to evaluate the effects of postoperative immune enhancing enteral nutrition on the immune system, inflammatory responses, and clinical outcome of patients undergoing major abdominal surgery.

METHODSThis study was designed as a multicenter, prospective, randomized and controlled clinical trial. One hundred twenty-four patients undergoing major abdominal surgery were randomly assigned to receive either an immune enhancing enteral diet or an isocaloric and isonitrogenous control enteral diet for seven days. Enteral feeding was initiated 24 hours after surgery. Host immunity was evaluated by measuring levels of IgG, IgM, IgA, CD4, CD8, and CD4/CD8, and the inflammatory response was determined by assessing IL-1alpha, IL-2, IL-6, IL-10, and TNF-alpha levels. Infectious complications were also recorded.

RESULTSOne hundred twenty patients completed the study and four patients were excluded. On postoperative day 9, among patients receiving an immune enhancing diet, IgG, IgA, CD4 and CD4/CD8 levels were significantly higher and TNF-alpha and IL-6 concentrations were significantly lower compared to the control group. Moreover, among patients receiving an immune enhancing diet, when comparing preoperation to day 9 postoperation levels, increases in IgA, CD4, and CD4/CD8 levels were significantly higher than in control patients and increases in TNF-alpha concentrations were significantly lower. No statistically significant differences were found between the two groups with regard to infectious complications.

CONCLUSIONSPostoperative administration of immune enhancing enteral nutrition in patients undergoing major abdominal surgery can positively modulate postoperative immunosuppressive and inflammatory responses.
