?AlM: To evaluate the long - term effects of laser peripheral iridectomy ( LPl ) and trabeculectomy in treating early chronic angle-closure glaucoma.
?METHODS: Ninety-eight patients (102 eyes) with early chronic primary angle-closure glaucoma were randomly divided into two groups. Group A of 50 patients (54 eyes) was treated with LPl and group B of 48 patients (48 eyes) with trabeculectomy. After 3 - 8y of follow - up observation, comparison would be made from the perspectives of postoperative eyesight, intraocular pressure, anterior chamber angle, visual field and cup/disc ratio ( C/D) .
?RESULTS:ln group A, 24 eyes with eyesight declining, 22 eyes with theintraocular pressure>21mmHg (1mmHg=0. 133kPa), 21 eyes with chamber angle synechia >180o, 21 eyes with visual field narrowed, 21 eyes with C/D ratio enlarged. The results of group B for the same items were 10, 5, 4, 4, 4 eyes respectively. The comparative difference was statistically significant (P<0. 05).
?CONCLUSlON:Good effects will be achieved for early-stage chronic angle - closure glaucoma with surgical method. Trabeculectomy is obviously better than LPl for the long-term effects.

Objective To study the correlation between 8-Iosmerie Porastglnadin-2a(8-iso-PGF2α) 、hypersensitive C-reactive protein(hs-CRP) and coronary heart disease(CHD). Methods 153 CHD patients were divided into 3 groups,including 52 cases of acute myocardial infarction(AMI) ,50 cases of unstable angina(UAP) ,51 cases of stable angina(SAP) and control group consisted of 50 healthy people. The levels of hs-CRP and 8-iso-PGF2α were measured. Person correlation analysis was used to analyze the relationship between the level of hs-CRP and 8-isoPGF2α. Results The levels of hs-CRP and 8-iso-PGF2α were significantly higher in AMI, UAP and SAP group than those in control group(all P ＜0.05). Compared with SAP group,the levels of hs-CRP and 8-iso-PGF2α were increased in AMI and UAP groups (all P ＜ 0. 05) . The level of hs-CRP was positively associated with the level of 8-iso-PGF2α. Conclusion hs-CRP and 8-iso-PGF2α should be the markers of coronary atherosclerosis and involved in the process of CHD. The levels of serum hs-CRP and 8-iso-PGF2α were correlated with the severity of CHD.

Based on the fact that the signals of electroencephalogram (EEG) possess non-linear and non-stationary properties, Hilbert-Huang Transform (HHT) was proposed for the EEG analysis of driving fatigue. Firstly, C4-lead EEG was selected, and the data of normal driving state and fatigue driving state was analyzed by HHT to explore the differences. Then O2-lead EEG was chosen for contrastive analysis of differences between the different leads. It was found through the analysis that the EEG signals had different Hilbert marginal spectrums for different states, and there were also some differences at the same state for the two leads. It can be certain that HHT can well distinguish different states of drivers as a novel approach for driving fatigue detection, and the selected lead may affect detectable results to some extent.

Objective To study the recovery mechanism of dysphagic patients after stroke using functional magnetic resonanee imaging(fMRI). Methods Thirteen patients with dysphagia caused by unilateral cortical or subcortical lesions were recruited into a dysphagia group,and eight age-matched healthy volunteers were recruited as controls.Both grouDs performed experimental volitional swallowing tasks during fMRI studies.All patients of the dys-phagia group received rehabilitation treatment targeting dysphagia.Of the 13 dysphagia patients,7 reached almost complete recovery and were identified as recovered in follow-up fMRI studies.A 3.0 T MR scanner and echo planar imaging(EPI)T_2 WI sequence were employed to obtain the fMRI data.SPM2 software was used for post-processing of the fMRI data and displaying activated brain maps.Lateral index(LI)was calculated as LI:(C-1)/(C+I).Paired t tests were used to compare activated brain volume before and after complete recovery. Results Consistent activation of the bilateral primary sensorimotor cortex,anterior cingulated gyrus and the bilateral insular cortex were observed in the control group. Activation of the pons,medulla,left cerebellum,left prefrontal area,right occipital area and the left insular cortex were observed in the dysphagia group.Activation was observed in the bilateral primary sensorimotor cortex.bilateral prefrontal area,bilateral superior temporal gyrus,left insular cortex,bilateral frontal o-pereulum and anterior cingulated gyrus in the recovered patients.The total activated volume before recovery in the ip-silesional hemisDhere was significantly less compared with the contralesional hemisphere in the dysphagia group.In the recovered patients,both the activated brain volume of the ipsilesional hemisphere and value of LI were significant-ly larger than those at the initial examination.Conclusions Decreased activation in the sensorimotor cortex,the in-sular lobe and the cingulate gyms might be causes.of dysphagia.Compensation by the contralesional hemisphere in the early stages and then the restoration of the ipsilesional hemisphere after recovery may be mechanisms of dysphagia recovery in stroke patients.

Objective To investigate the effects of partial body weight supported treadmill training (BW- STT) on post-stroke depression (PSD) and on patients' quality of life.Methods Sixty patients with PSD were re- cruited and divided into a training group (n=30,male 17,female 13) and a control group (n=30,male 16,fe- male 14).All patients were treated with routine internal medication and rehabilitation.The patients of the training group also received BWSTT in addition to their routine treatment.All patients' neurological impairment was evaluated using the Modified Edinburgh-Scandinavian Stroke Scale (MESSS).The Hamilton depression scale (HAMD) was used for evaluating the degree of depression.The Fugl-Meyer scale and the Barthel index were used to assess ambula- tion and balance,and facility in the activities of daily living.All patients were assessed before and after the treat- ment.Results After four weeks of treatment,depression in the training group had improved significantly more than in the control group.Conclusion BWSTT intervention is very important for patients with PSD:it can reduce the degree of depression and improve the quality of life.

OBJECTIVETo preliminarily investigate the influence of hypoxia on human umbilical vein endothelial cells (HUVECs), and the effect of Ginkgo biloba extract 50 (GBE50) on it.

METHODSFlow cytometry, TUNEL, RT-PCR, Western blot, etc. were applied, to study the effect of hypoxia and GBE50 on endothelial cells.

RESULTSAfter being interfered by hypoxia for 24 h, the levels of reactive oxygen species (ROS) in HUVECs and the apoptotic rate either in the early or in the late stage significantly increased, and accompanied with the increased levels of endothelin-1 mRNA (ET-1) and endothelial oxide synthase (eNOS) protein. However, when HUVECs were pretreated with GBE50 (25 [microg/ml) 4 h before hypoxia, the apoptotic rate in the early or late stage and expression of ET-1 mRNA significantly decreased (P < 0.05), and the heightened ROS level and eNOS expression partially decreased (P > 0.05).

CONCLUSIONHypoxia can induce endothelial dysfunction, which could be partially or significantly reversed by GBE50, it shows a certain protective effect on hypoxia induced endothelial dysfunction.

Objeetive To investigate the clinical significance of combined detection of lipoprotein associated serum phospholipase A2 (Lp-PLa2),homocysteine (Hcy) and cystatin C (CysC) in the diagnosis of hypertensive disorders complicating pregnancy (HDCP).Methods From January 2013 to May 2016 in Changan Hospital,selected 113 cases of pregnancy induced hypertension patients as the observation group,and were divided into three group A,B and C (group A:55 cases of HDCP patients,group B:32 cases of mild preeclampsia and group C for patients with severe preeclampsia 26 cases).At the same period,selected 50 cases of normal college pregnancy as control group,serum Lp-PLa2 (enzyme-linked immunosorbent assay),Hcy (cyclophorase method) and CysC (particle enhanced turbidimetric method),the test results were analyzed and compared.Results Serum Lp-PLa2,Hcy and CysC test results in the control group,the observation group A,observation group B and observation group C increased significantly,in the observation group C increased most obviously.Compared with the control group,the serum levels of Lp-PLa2,Hcy and CysC in the observation group were significantly higher,the difference was statistically significant (F=8.102,7.231 and 6.926,all P＜0.05).Pearson correlation analysis showed that there was a positive correlation between serum Lp-PLa2,Hcy and CysC and blood pressure (r=0.71,0.69,0.63,all P＜0.05).The abnormal rate of serum Lp-PLa2,Hcy and CysC for three joint detection was higher than that of single detection,and the difference was statistically significant (x2 =6.725,P＜0.001).The abnormal rate of serum Lp-PLa2,Hcy and Cys single test results increased with the exacerbation of HDCP,and the difference was statistically significant (x2=9.351,P＜0.000).Conclusion Serum Lp-PLa2,Hey,CysC and pregnancy would be closely related to the occurrence and development of hypertension syndrome,so combined detection of HDCP can improve the detection rate of abnormal results,and it has important clinical significance for early diagnosis and prognosis of HDCP.

OBJECTIVETo observe the effect of adenovirus-mediated overexpression of AMP-activated protein kinase (AMPK) on apoptosis of hepatic stellate cell line LX2.

METHODSAfter adenovirus infection of the LX2 cells, the exogenous gene expression was detected by Western blotting, and cell apoptosis evaluated by flow cytometry with PI staining. Agarose gel electrophoresis was performed to detect the DNA ladder, and the expressions of caspase-3, Bcl-2 and Bax are detected by Western blotting.

RESULTWith AMPK overexpression, apoptotic peak and DNA ladder of the infected cells appeared, and pro-caspase-3 was activated to transform into caspase-3 accompanied by up-regulated Bax expression, whereas Bcl-2 expression was hardly detectable by Western blotting.

CONCLUSIONOverexpression of AMPK mediated by the adenovirus can induce LX2 cell apoptosis, possible as a result of up-regulated Bax expression with low Bcl-2 expression.
