Objective To investigate the protective effects of Green Tangerine induced hypertension and mild hypothermia on focal cerebral ischemia and reperfusion and local cerebral glucose utilization(LCGU)in the in- farction rim in rats.Methods A total of 64 rats were used and randomly divided into a control group,a Green Tan- gerine induced hypertension group,a mild hypothermia group and a combination therapy group.The neurologic defi- cits,infarct size and LCGU were observed in the rats with focal cerebral ischemia and reperfusion.Results Com- pared with the control group,the neurologic deficits(P

Objective To evaluate the diagnostic value of dual-source CT angiography (DSCTA) for intracranial aneurysms.Methods The data of DSCTA and digital subtraction angiography (DSA) were collected from 95 patients with subarachnoid hemorrhage (SAH).The efficacies of detection and description of morphologic features of intracranial aneurysms were analyzed retrospectively.Results A total of 117 aneurysms in 88 patients were detected with DSCTA.Two patients were suspected of having aneurysms,and no aneurysrms were detected in 5 patients.These patients were reexamined with DSA,4 were diagnosed as having aneurysm,and the aneurysms were not detected in 3 patients.DSA results were considered as gold standard,the specificity,sensitivity and accuracy of DSCTA for the detection of intracranial aneurysms were 100％,96.7％and 96.8％,respectively.The larger volume of intracranial aneurysm was,the higher the sensitivity of DSCTA diagnosis would be.Even for small aneurysms,the sensitivity of DSCTA diagnose was more than 90％.In addition,tmeasurement results of the maximum diameter and neck width of aneurysms measured by DSCTA were almost consistent with DSA.Condclusions SCTA is a non-invasive,quick,reliable,and effective method,and can provide accurate imaging information for surgery.The specificity and sensitivity of the diagnosis of aneurysms with DSCTA are almost the same with DSA.It has more advantages than DSA in the emergency operation of intracranial aneurysms.

OBJECTIVE:To investigate the effects of UGT1A6 and UGT1A9 gene polymorphisms on blood concentration of valproic acid in Han epileptic patients.METHODS:Totally 107 Chinese Han epileptic patients were selected from outpatient department of our hospital during Jan.2014-Apr.2015.They were given valproic acid monotherapy treatment for 3 months to 6 years.The steady state concentration ofvalproic acid was detected by EMIT.UGT1A6 (rs2070959,rs6759892) and UGT1A9 (rs13418420,rs2741045,rs2741049,rs6731242,rs72551330) genotypes were detected by MALDI-TOF-MS.The correlation of gene polymorphism with con centration dose ratios (CDR) of valproic acid was investigated.RESULTS:UGT1A9 rs72551330 mutation had not been detected,and the frequency of genotypes in other 6 sites were all in line with Hardy-Weinberg balance (P＞0.05).The CDR of valproic acid in pa tients with UGT1A6 rs2070959,rs6759892 mutation (AG+GG or TG+GG type) were significantly lower than those with wild homozy gote (AA or TT type),with statistical significance (P＜ 0.05).There was no statistical significance in CDR of valproic acid among patients with UGT1A9 rs13418420,rs2741045,rs2741049 and rs6731242 wild homozygote and mutation (P＞0.05).CONCLUSIONS:UGT1A6 rs2070959,rs6759892 gene polymorphisms of Han epileptic patients are associated with blood concentration of valproic acid,and the patients with UGT1A6 rs2070959,rs6759892 mutation need more dose ofvalproic acid.

Objective To evaluate the clinical effect of breast implant on congenital mammary dysplasia with mild pigeon chest deformity. Methods From January 2003 to July 2009,10 cases of female mammary dysplasia (between 20 to 31 years of age) underwent breast implant surgery. Subpectoral placement and transaxillary incision were selected. The surgeon marked the range of the operation on the skin, made a 3-4 cm incision in the armpit, separated the tissue until the pectoral lateral margin, cut the pecto-ralis fascia and bluntly created a suitable pocket under the pectoralis major for the implant. After the implant was placed in the pocket, the incision was closed. Results Ten cases of breast implant surgery did not pose the complications of local skin necrosis, infection, implant shift, heart and lungs dysfunction after one year follow-up. The appearance of anterior chest wall deformity was markedly improved. Conclusions The application of breast implant surgery in the treatment of congenital mammary dysplasia with mild pigeon chest deformity should be promoted, because of the double surgical effect of easy performing, minimal surgical damage, perfect breast shape and concealed deformity.

Objective To investigate the feasibility of ~1H-MR spectroscopy(~1H-MRS)imaging to quantitatively detect fatty liver.Methods Twenty patients with fatty liver and 11 healthy volunteers underwent plain CT scan,conventional MR imaging and ~1H-MRS analysis.The blood lipid and liver function were tested on the same day as the MR examination.~1H-MRS sequence measured the peaks of H_2O and lipid,and the areas under the peaks.The relative contents of the lipid compound were calculated,and compared with the results of CT scan and liver function tests.Results The CT values of the normal group and the fatty liver group were(59?9)HU and(24?11)HU respectively.On ~1H-MRS a protruding high H_2O peak and a flat low lipid peak were observed in the normal group,while the protruding high H_2O peak and a high lipid peak appeared in the fatty liver group.The values of lipid peak in the normal group and the fatty liver group were(0.05?0.01)?10~5,(0.70?0.24)?10~5 respectively(t=4.32,P0.05),the areas under the lipid peak were(1.36?0.73)?10~9、(2.35?1.15)?10~9 respectively(t=5.21,P0.05).Conclusion ~1 H-MRS imaging is feasible to quantitatively detect liver fat and is a non-invasive method for detecting early fatty liver.

Objective To explore the pathologic changes in the brain areas corresponding to specific cognitive function and underlying mechanism of cognitive impairment in patients with epilepsy by DTI study.Methods Forty-four Patients and 20 control subjects received the test of Wechsler Adult Intelligence Scale and the Diffusion-Tensor Imaging examination.Mean diffusivity (MD) and fractional anisotropy (FA) in the normal appearing white matter of interested area were measured.T test was employed to compare the MD and FA between patients and healthy controls,patients with normal and impaired FIQ respectively.The relationships between FIQ and DTI value were analyzed by Bivariate correlations.Results VIQ (100.52?17.63),PIQ (95.10?16.72) and FIQ (98.19?17.76) of the patients with epilepsy were significantly lower than those of health controls (VIQ,PIQ and FIQ were 109.77?13.54,108.11? 12.17 and 109.81?10.57,respectively).Significant reduction of FA in both side of posterior limb of internal capsule (P

Objective To investigate reliability of the infra-nipple broken line incision for breast augmentation.
Methods From January 2012 to January 2013, 15 patients underwent primary bilateral retromuscular breast augmentation with round textured silicone-gel implants and a novel infra-nipple broken line incision. Preoperatively, a semicircular incision was marked along the inferior base of the nipple. It was then extended bilaterally using two transverse right-angled geometric broken lines within the pigmented areolar skin. Follow-up was performed to evaluate the sensation of nipple-areolar complex, the scar, and the shape and texture of the breasts.
Results The average follow-up was 6.7 months. Most of the patients complained of paresthesia of the nipple or breast skin, but transient decreased sensation improved within 3 months. No patients showed permanent sensory changes of the nipple areolar complex at a minimum follow-up of 4 months. The scars were imperceptible in all patients.
Conclusion We believe that for selected patients, the infra-nipple broken line incision is a practical and reliable method to achieve aesthetic result.

OBJECTIVETo observe the therapeutic effects of beta-elemene combined DC/Dribble vaccine in treating mice with hepatic cancer, thus exploring their anti-tumor mechanisms.

METHODSDentritic cells were derived from Balb/c mice's spleen and their phenotypes were identified. Using hepatic cancer cell line BNL1MEA.7R.1 (abbreviated as BNL) originated from Balb/c mice as target cell, DC/Dribble vaccine was prepared via raising the antigen representing carrier autophagosomes (DRips in Blebs, DRibbles), which were rich in tumor antigen information. The mice previously immunized were divided into 4 groups, i.e., the control group, the beta-elemene group, the vaccine group, and the combined group. The PBS was subcutaneously and intraperitoneally injected to mice in the control group. The beta-elemene was intraperitoneally injected at the daily dose of 50 mg/kg to mice in the beta-elemene group and the combined group for 7 successive days. DC/Dribble vaccine was injected into the lymph node of mice in the vaccine group and the combined group on the 1st day, and DC/Dribble vaccine was subcutaneously injected on the 3rd day and the 5th day. All the mice were sacrificed on the 10th day. Their spleens were obtained sterilely, and the suspension was incubated with or without Dribble. The cells were inoculated for 72 h. The contents of IFN-gamma in the supernatant were measured by ELISA. In addition, the spleen cells obtained from the combined group were incubated with different stimulations for 72 h, which were then divided into the control group, the DRibble group, the DC group, and the DC/Dribble vaccine group. The supernatant of cultured cells were collected and the contents of IFN-gamma were measured by ELISA. The liver tumor-bearing mouse model was established, and then the BNL bearing mice were randomly divided into 4 groups, i.e., the control group, the beta-elemene group, the vaccine group, and the combined group. The treatment ways were the same as the immune ways. The tumor size and the survival period were observed in each group. On the 23rd day the mice were sacrificed. The tumor tissue was stripped and stained by HE staining. The pathomorphological manifestations of the tumor tissue were observed by light microscope.

RESULTSIn vitro detection of mice immunized previously by different ways showed that the secretion of IFN-gamma was significantly higher in the combined group than in the rest groups (P < 0.01). The secretion of IFN-gamma was significantly higher in the beta-elemene group and the vaccine group than in the control group (P < 0.01). The spleen cells could be stimulated to secrete a large amount of IFN-gamma in the vaccine group and the Dribble group (P < 0.01). When the beta-elemene was 10 microg/mL as the stimulating dose, the secretion of IFN-gamma obviously increased (P < 0.01). In vivo observation showed that the growth velocity of tumors in mice of the combined group was slowed down. There was statistical difference in the tumor area or the survival period of mice in the combined group, when compared with the other groups (P < 0.01). In HE staining, the surrounding connective tissues of the tumor were wrapped tightly and compactedly, with infiltration of a large amount of inflammatory cells.

CONCLUSIONSbeta-elemene combined DC/Dribble vaccine could induce specific immune cells to secrete secretory cells, thus exerting its anti-tumor effect. Its immunological effects might be associated with enhancing the DC antigen presenting function.
