Objective To study trabeculectomy with adjustable sutures on the ocular function score in pa-tients with angle-closure glaucoma .Methods 98 cases ( 134 eyes ) were randomly divided into the two groups , the control group(n=49 cases,66 eyes) and the observation group (n=49 cases,68 eyes).The patients in the control group were operated through trabeculectomy ,while the patients in the observation group were operated through trabe-culectomy with adjustable sutures .The occurrence of the two groups of patients intraocular pressure changes , and recovery of sight,shallow anterior chamber before and after surgery three months were observed .Postoperative 1d,3d, 1m and 3m ocular function score were compared .Results Postoperative 3 months IOP were significantly lower ( t=3.921,5.746,all P<0.01),and compared with the control group ,the observation group significantly decreased (t=2.680,P<0.05).Postoperative 3 months visual acuity significantly improved in patients (t=2.460,2.976,all P<0.05),and compared with the control group,the observation group improved more significantly (t =2.062,P <0.05).The incidence of postoperative shallow anterior chamber were 12.1% in the control group and 2.9% in the observation group Shallow anterior chamber in observation group was significantly less than that in the control group (χ2 =7.98,P<0.01).The two groups of patients after ocular surface scores were decreased in the observation group after 1d,3d,1m and 3m and ocular scores were lower than that of the control group ( t =2.1901,2.680,3.172, 3.013,all P<0.05).Conclusion Trabeculectomy with adjustable sutures can promote the recovery of angle-closure glaucoma,ocular function.

Objective The localization of AQP4 was studied in the brain,especially,in the periventricular organs,such as ependyma,choroid plexues,area postrema(AP) and neurohypophysis,and telencephalon as well as two kinds of endocrine gland:pineal gland and adenohypophysis,so as to provide morphological basis for water transport and balance,the secretion and regulation mechanisms of endocrine gland in the brain. Methods Immunohistochemical staining techniques(LAB-SA,BCIP/NBT) were used. Results AQP4 was most abundantly expressed in the tissues directly contacting with CSF,including the cerebral pia mater,ependyma lining of ventricules and the aqueductal system and choroid plexues.Heavy express of AQP4 was also found in the perivascular glial processes of the brain tissue.In addition,AQP4 was also distributed to the pyramidal cell layer of hippocampus,granular cell layer and polymorphic cell layer of dentate gyrus,adenohypophysis(intermedius included) and pineal gland cells as well as the periventricular organs such as area postrema(AP) and neurohypophysis.Conclusion The localization of AQP4 indicates that AQP4 is involved in not only the transport and balance of water,electrolyte metabolism and the regulation of secretion of the endocrine gland,but also in the neuroendocrine activity of the hypothalamus.

Objective To analysis the risk factors for elevated ALT level in patients with Non-alcoholic fatty liver diseases (NAFLD).Method Fifty-six (male 25,female 31) NAFLD patients with elevated ALT and 153 NAFLD patients (male 64,female 89) with normal ALT and 160 (male 80,female 80) health subjects were selected.ALT was detected by rate assay,total cholesterol (TC),triglycerides (TG),low-density lipoprotein cholesterols (LDL-C),high-density cholesterol (HDL-C) and uric acid (UA) were detected by enzymatic method.Free fatty acid (FFA) was detected by immunoturbidimetry assay.Spearman correlation was used to analysis the relation between ALT and TC,TG,LDL-C,HDL-C,UA and FFA.Logistic regression was used to analyses the risk factor for elevated ALT level.Results TC,TG,LDL-C,UA and FFA levels were significantly higher in NAFLD group (including normal ALT group and elevated ALT group) than those in health group no matter male and female,HDL-C was significantly lower in these two groups when compared to control group,but binary logistic regression and spearman analysis showed that only UA and FFA were the risk factors for elevated ALT level and significantly positively correlated with ALT level,abnormal UA and FFA for male were associated with 3.96-fold(95CI％ =1.40～ 11.22,P=0.010) and 3.27-fold (95 ％ CI =1.14 ～ 9.40,P =0.028) of increased risk of elevated ALT level respectinely,correlation coefficient were 0.40(P=0.000),0.29(P=0.006),Meanwhile Exp(B) of elevated ALT level for female with abnormal UA,FFA were 4.49 (95CI％=1.79～11.28,P=0.001) and 3.17 (95CI％ =1.25～8.04,P=0.015),correlation coefficient were 0.34 (P =0.000),0.27 (P =0.003).Conclusion Elevated ALT level was not associated with dyslipidemias,but related to UA and FFA.They can be used as candidate markers for predicting severity of liver damage.

Objective To observe the expression of neuroglobin in brain of rat with septic shock,and study the protective effect of neuroglobin.Methods Sixty male SD rats were randomly di-vided into two groups,30 rats in each.The rats in group M were injected LPS 10 mg/kg through tail vein to establish septic shock model,the success standard of septic shock was systolic blood pressure dropping to 60% of the basic values;the control group were given equal volume of NS.The levels of rat TNF-α,IL-6 and NGB in serum at the time points of before LPS injection (T0 ),1 h (T1 ),2 h (T2 ),4 h (T3 )and 6 h(T4 )after LPS injection were measured using ELISA kits.NGB and caspase-3 protein expression in brain were determined using Western blotting.Results Compared with group C and T0 ,the TNF-α,IL-6 concentrations in serum and caspase-3 in brain were increased significantly at T1-T4 (P <0.05),NGB protein content in serum and brain at T3 and T4 were increased significantly (P <0.05).Conclusion Cell apoptosis and inflammatory response are discovered in the brain during septic shock.NGB is over-expressed in brain of rats with septic shock,which may play a role of pro-tective function.

Healthy male Wistar rats were prepared as model of precancerous lesion of gastric mucosa. The tongue, pH of tongue surface, dropped cells from tongue fur, histology of tongue. and corresponding gastric mucosa, pH of gastric juice, mucosal histological changes in both groups were observed. Results revealed that, in the rats with precancerous lesion, the tongues were bare or only with little fur, dark purplish tongue with petechia. pH of both tongue and gastric juice were high, which were both coincided with the syndrome type of asthenic gastric - qi and blockage of collaterals by stagnant blood.

Objective To detect the expressions of circulating microRNAs (miRNAs) of peripheral whole blood in Alzheimer's disease (AD) and investigate the potential roles of the miRNAs as diagnostic bi omarkers for Alzheimer's disease.Methods Peripheral blood samples were obtained from 110 AD patients and 150 age-and gender-matched normal controls.The concentrations of seven candidate miRNAs,including miR-9,miR-29a,miR-29b,miR-101,miR-181c,miR-137and miR-126,were measured with a real-time quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) method.The data of two groups were collected and analyzed by SPSS 19.0 software.Results It was found that miR-29a (P=1.12×10-5) and miR-101 (P=6.24× 10-7) were markedly down-regulated in peripheral blood of AD patients compared with normal controls.In addition,logistic regression analysis revealed peripheral whole blood miR-29a/101 combination could be a potential biomarker of AD with better specificity (82％) and sensitivity (75％).Conclusions miR-29a/101 combination in peripheral whole blood may serve as a useful noninvasive diagnostic biomarker for AD.

Objective To investigate the expression of C/EBP homology protein (CHOP) in peripheral brain tissue of patients with severe traumatic brain injury (TBI) and its correlation with the injury severity.Methods The study included peripheral brain tissues of 41 TBI patients (TBI group).Another 16 autopsy specimens succumbed to other diseases (except for TBI or other central nervous system diseases) were selected as controls.The control group and TBI group were subdivided into immaturity group (≤18 years),adult group (18-59 years) and elderly group (＞59 years).According to Glasgow Coma Scale (GCS) on admission,TBI group was classified as severe TBI group (GCS of 6-8) and particularly-severe TBI group (GCS of 3-5).CHOP expression in peripheral tissues after TBI was compared in between different age,gender and GCS.Nerve cell apoptosis was detected by TUNEL technique and correlation between CHOP level and apoptotic number was analyzed.Results There were no age and gender differences regarding CHOP expression in control group (P ＜ 0.05).Compared with control group,expression of CHOP presented notable up-regulation in TBI group (P ＜ 0.05).Expression of CHOP presented no gender difference in TBI group (P ＞ 0.05),but its expression was lower in the aged than in adult or immaturity (P ＜ 0.05) as well as notably higher in particularly-severe TBI group than in severe TBI group (P ＜ 0.05).Nerve cell apoptosis in TBI group was far greater in number than that in control group (P ＜0.05).A positive correlation was observed between CHOP level and apoptotic index (r =0.72,P ＜ 0.05).Conclusion Expression level of CHOP after TBI is closely related to the injury severity and nerve cell apoptosis,but the apoptosis pathway induced by CHOP may not be a major factor in secondary brain injury after TBI in the aged patients.
