Objective To observe the time-dependent changes of astrocytes and microvessels in the ischemic core and surrounding areas.Methods Glial fibrillary acidic protein (GFAP)was measured by HE,and CD31 by immunohistochemistry as markers in post-mortem specimens from ten patients,who died of cerebral infarction.Results Each section of the infarcted brains was divided into four areas (the area 0-3).GFAP expressed a little in area 0 and 1,increased in a time-dependent manner in area 2 and 3;CD31 die not expressed in area 0,expressed a little in the area 1,and increased in area 2 and 3 continuously.Conclusions The proliferation of astrocytes and microvessels may play a significant role in the process of restoration after cerebral infarction.

Objective To investigate the operative methods and their efficacy of the modified decompressive craniectomy in combination with indirect revascularization for the treatment of massive cerebral infarction. Methods The clinical data of 15 patients with massive cerebral infarction who underwent modified decompressive craniectomy in combination with encephaloduroarteriomyosynangiosis were analyzed retrospectively. The clinical efficacy was assessed according to the mortality, Barthel Index and modified Rankin scale. Results All the patients were followed up, and 12 patients survived 3 months after operation, of those, 4 had a good functional outcome; 11 patients survived 6 month after operation, of those, 7 had a good functional outcome. Conclusions The modified decompressive craniectomy in combination with indirect revascularization for the treatment of massive cerebral infarction could effectively treat massive cerebral infarction and increase the survival rate and life quality of patients, however, the surgical timing, surgical indications and surgical skills are needed to master accurately.

OBJECTIVETo investigate the therapeutic effect of Yiqi Huaju Recipe (YHR) combined with routine therapy on the blood pressure, the blood pressure variability and other cardiovascular risk factors in hypertension patients complicated with metabolic syndrome (MetS).

METHODSTotally 43 hypertension patients complicated with MetS were recruited in this study and randomly assigned to the treatment group (22 cases, treated with basic routine treatment +YHR) and the control group (21 cases, treated with basic routine treatment + placebo). The treatment course was 12 weeks. Detected were parameters such as 24-h ambulatory blood pressure monitoring (ABPM), body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), homeostatic model assessment for insulin resistance (HOMA-IR), fasting glycosylated hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), 2 h postprandial plasma glucose (2 h PPG), fasting plasma insulin (FPI), serum lipid, etc.

RESULTSThe anthropometric parameters and plasma glucose levels (except HbAlc) were obviously lowered after treatment than before treatment in the treatment group (P < 0.01, P < 0.05). Besides, better effects were obtained in the WC, WHR, 2 h PPG, FPI and HOMA-IR (P < 0.05). The average blood pressure amplitude, the blood pressure variability, and blood pressure load at any time point were more obviously improved in the two groups after treatment than before treatment (P < 0.01, P < 0.05). Besides, partial indices were better in the treatment group than in the control group (P < 0.01, P < 0.05).

CONCLUSIONSYHR combined with routine therapy exhibited better effect on reducing the blood pressure amplitude, the blood pressure variability, and the blood pressure load in hypertension patients complicated with MetS. It could also effectively decrease the risk of other vascular disease.

Objective To evaluate the effect of health education in controlling the iodine deficiency diserders(IDD) in order to provide reference data for the further prevention and control. Methods Each village of 3 towns in Congjiang County was selected in 2007, where the health education lasting for 10 months had been implemented in the school students of 3-6 grade and the villagers. The school students of 3-6 grade and 30 housewives in the villagers were investigated for their IDD control knowledge, the salt consuming conditions as well as the sales of both rough and fine salt at a salt retail site in each village before and after the health education was implemented. Results The awareness rate of the knowledge of IDD control in the students and housewives was 91.4% (581/636) and 78.3% (282/360), respectively after intervention, which significantly increased (χ2= 532.044, 326.117, both P < 0.01) compared with the rate of 28.2% (184/652) and 11.4% (41/360) before intervention. The proportion of consuming fine salt was 91.8%(146/159) and 95.6%(86/90), significantly inereased(χ2= 236.623, 135.350, both P < 0.01) compared with 6.1%(10/163) and 7.8% (7/90) found before intervention. The selling proportion of fine salt at the salt retail site in the village was 60.0%(900/1500), significantly increased(χ2= 824.176, P < 0.01) compared with 10.0%(150/1500) before intervention. Conclusions Health education and promotion is solid foundation for effectively controlling IDD, through which the students and villagers are actively and voluntarily involved in the program and hence have formed good living and hygiene habits, thus expected effect has been obtained.

OBJECTIVETo explore clinical outcomes and advantages of anterior small-incision focus debridement with posterior internal fixation through muscle spa ring in treating patients with lumbar spinal tuberculosis.

METHODSFrom February 2010 to February 2014, totally 82 patients with lumbar spinal tuberculosis were treated by posterior individual fixation with small-incision focus debridement,including 50 males and 32 females with an average of 50.5 years old. All patients were divided into two groups according to different procedures. Forty-nine patients in group A were treated with anterior small-incision focus debridement with posterior internal fixation through muscle spa ring at stage I ; and 33 patients in group B were treated with focus debridement with posterior internal fixation by extraperitoneal approach at stage I . Postoperative mechanical ventilation time, preoperative and postoperative Cobb angle, visual analogue scale (VAS), erythrocyte sedimentation rate (ESR) and Frankel grading were observed and compared. Postoperative complications, stability of internal fixation and bone union were compared.

RESULTSAll patients were followed-up from 15 to 36 months with an average of 23.7 months. Psoas abscess of three patients in group A and 1 patient in group B on the opposite side increased and were healed by the secondary apocenosis. The other 78 cases were healed at stage I, and no sinus tract formation, incisional hernia, leakage of cerebrospinal and occurrence of spinal tuberculosis were occurred. Fracture healing time ranged from 3 to 7 months with an average of 4.6 months. Postoperative mechanical ventilation time and VAS score in group A was better than group B. There were no statistical differences in Cobb angle, ESR and Frankel grading at the final following-up between two groups.

CONCLUSIONAnterior small-incision focus debridement with posterior internal fixation through muscle spa ring in treating patients with lumbar spinal according to degree of damage is a safe and effective method.

OBJECTIVETo observe the effects of ginkgo flavone aglycone (GA) on oxidized low-density lipoprotein (ox-LDL) induced oxidative injury of human aortic endothelial cells (HAECs) and its mechanisms.

METHODSHAECs were in vitro cultured. Then they were divided into 6 groups, i.e., the vehicle control group, the ox-LDL group, the GA 30 mg/L group, the GA 60 mg/L group, the GA 90 mg/L group, and the Vit E group. The oxidative injury model was duplicated in the rest 5 groups by adding 150 mg/L ox-LDL except the vehicle control group. GA was added as intervention at corresponding dose to the GA 30 mg/L group, the GA 60 mg/L group, and the GA 90 mg/L group. Vit E at 200 micromol/L was administered to those in the Vit E group. The survival rate of HAECs was detected by MTT. The contents of reactive oxygen species (ROS) in HAECs were determined by CM-H2DCFDA fluorescent probe. The contents of NADPH oxidase were detected by ELISA. The levels of malondialdehyde (MDA) were measured by thiobarbituric acid (TBA) test. The contents of nitric oxide (NO) were determined by Griess reagent method. The contents of superoxide dismutase (SOD) were detected by xanthine oxidase method.

RESULTSCompared with the vehicle control group (100.00%), the cell survival rate in the ox-LDL group (70.68%) obviously decreased (P <0.05). The cell survival rate was 88. 95% in the VitE group, 83.25% in the GA 30 mg/L group, and 94.93% in the GA 60 mg/L group, obviously higher than that of the ox-LDL group (70.68%, P <0.05). The optimal effects were shown in the GA 60 mg/L group. Compared with the vehicle control group, the contents of ROS, MDA, and NADPH oxidase increased, the contents of NO and the SOD activity decreased in the ox-LDL group, showing statistical difference (P <0.05). Compared with the ox-LDL group, the contents of ROS, MDA, and NADPH oxidase decreased, the NO content and the SOD activity increased in the GA 30 mg/L group, the GA 60 mg/L group, and the Vit E group, showing statistical difference (P <0.05). The optimal effects were shown in the GA 60 mg/L group.

CONCLUSIONSGA could obviously inhibit ox-LDL induced synthesis of ROS, lower the contents of MDA, and elevate the levels of NO. Its mechanisms might be associated with increasing the activity of SOD and lowering the activity of NADPH oxidase.
