AIM: To compare the effects of different surgeries in the treatment of angle closure glaucoma with cataract and the improvement of quality of life.METHODS: The clinical data of 60 cases (60 eyes) with angle closure glaucoma and cataract who were admitted to the hospital between January 2014 and October 2016 were collected.According to the surgical method, they were divided into the control group (simple trabeculectomy, n=28) and the observation group (trabeculectomy combined with phacoemulsification and intraocular lens implantation, n=32).The changes of visual acuity and intraocular pressure before and after surgery were compared between the two groups.The incidence of postoperative complications was statistically analyzed, and the quality of life was compared between the two groups.RESULTS: Before surgery, there was no significant difference in visual acuity, intraocular pressure and anterior chamber depth between the two groups (P>0.05).At 4wk after surgery, the visual acuity of two groups increased and intraocular pressure decreased.The anterior chamber depth of observation group increased while that of the control group decreased (P<0.05).At 4wk after surgery, the visual acuity and anterior chamber depth of observation group were higher than that of the control group but intraocular pressure was lower than that of control group (P<0.05).The success rate of surgery and the opening rate of chamber angle after surgery in the observation group were higher than those in the control group (P>0.05).The incidence of postoperative complications in the observation group was lower than that in the control group (P<0.05).Before surgery, there was no statistically significant difference in quality of life score between the two groups (P>0.05).At 4wk and 3mo after surgery, the scores of the two groups increased (P<0.05), and the quality of life scores of observation group were higher than those of the control group at different time (P< 0.05).CONCLUSION: The success rate of trabeculectomy combined with phacoemulsification and intraocular lens implantation is high in the treatment of angle closure glaucoma with cataract.The regimen can improve the visual function, reduce the incidence of postoperative complications, and improve the quality of life of patients.

Objective To explore the influence of homocysteine(Hcy)on liver cystathionine-?-synthase(CBS)and methylenetetrahydrofolate reductase(MTHFR)system in apoE-/- mice,and determine the effects of atorvastatin and/or folate/vitamin B12 on liver CBS and MTHFR system.Methods Eighty male 6-week-old apoE-/- mice were randomly divided into two groups:65 mice were fed with a chow diet containing 2%(wt/vol)L-methionine(homomethionine group)and 15 mice were fed with normal saline(control group).Two months later,the 60 mice survived in homomethionine group were subdivided into four groups:group Ⅰ(untreated),Ⅱ(3 mg/kg atorvastatin),Ⅲ(3 mg/kg atorvastatin+2 mg/kg folate+30 ?g/kg vitamin B12)and Ⅳ(2 mg/kg folate+30 ?g/kg vitamin B12).After one month,Western blotting was performed to detect the liver CBS and MTHFR system protein expression in each group.Results The relative expression of liver CBS and MTHFR was significantly lower in group Ⅰ than in control group(P

AIM:To investigate the myocardial protective effect of endometrial stem cell ( EnSC)-derived cyto-kine cocktail ( EdCC) on myocardial ischemic reperfusion injury and the MEK-ERK signaling pathway.METHODS: A mouse model of myocardial ischemic reperfusion injury was established.Infarct area, cell apoptosis, and expression of cleaved caspase-3 and phosphorylatied ERK1/2 were determined by TTC/Evans blue staining, TUNEL assay and Western blot, respectively.RESULTS:The mesenchymal characteristics were observed in the EnSCs with expressing CD90 and in absence of CD34 and CD45.EdCC contained (6 811 ±312) ng/g epidermal growth factor (EGF) protein.The phospho-rylation of ERK1/2 markedly increased after injection of EdCC, but was abolished by MEK1 inhibitor PD98059 ( 5 mg/kg) .EdCC decreased the infarct area and apoptotic cell number in the border zone and inhibited caspase-3 activation. However, the effects were abolished by MEK1 specific inhibitor PD98059.EGF did not decrease the infarct area, but the EGF receptor antagonist AG-1487 (6 mg/kg) partly abolished the myocardial protective effect of EdCC.CONCLUSION:EdCC protects the myocardium from ischemic reperfusion injury via activating MEK1-ERK signaling pathway, indicating an essential role in the transmission of stem cell therapy from the cell transplantation to cytokine based strategy.

Objective To explore the risk factors affecting prognosis of children with Tourette syndrome(TS).Methods The follow-up visits were conducted on the clinical data of 98 cases with TS(85 male,13 female;aged 4-16 years old)from 1997 to 2005 in Wuhan children's hospital.All cases were consistent with the diagnostic criteria of TS in the 4th edition of Diagnostic and Statistical Manual of Mental Disorders(DSM-Ⅳ).The investigations were performed by the investigators who received special training using the unified questionnaire with the methods of direct inquiry or by telephone.The factors included sex,age,severity of TS,the primary symptoms,family history,coexisting diseases,basic diseases,perinatal abnormity and family-social relations.The prognosis of TS and these factors were analyzed by linear regression and stepwise regression with SPSS 12.0 software.Results About 16 cases lost follow-up and the other 82 cases with follow-up(72 male and 10 female)received retrospective review.They were 14 to 25 years old with complete data,and 50 cases healed,32 cases not healed.Results from non-conditional simple variant Logistic regression showed that such cases were associated with the following factors:age,family history of TS,severity of TS,coexisting diseases,basic diseases and perinatal abnormity(Pa0.05).Out of 6 suspicious factors,there were coexisting diseases(OR=84.088,95%CI 10.850-651.682),severity of TS(OR=13.956,95% CI 2.412-80.762),and family history of TS(OR=27.127,95% CI 1.047-702.831)of risk factors.Conclusion The long-term prognosis of children with TS may be related with coexisting disease,severity of TS and family history respectively.

Objective To evaluate the efficacy and safety of levetiracetam (LEV) monotherapy on children with epilepsy.Methods Forty-one children (26 cases were male,15 cases were female) with epilepsy aged 7 months to 13 years were treated with LEV as monotherapy.These patients were selected from Department of Neurology ,Wuhan Children′s Hospital, from Aug.2007 to Aug.2009.The starting do-sage of LEV was (13.6?4.7) mg?kg-1?d-1,twice daily,and its objective dosage was (25.7?7.5) mg?kg-1?d-1,twice daily.LEV monotherapy was investigated by a self-controlled and open-label research,and the follow-up period ranged from 6 months to 2 years.Results The effective rate was 68.3% (28 cases),with 39.0% (16 cases) achieving seizure freedom in LEV monotherapy of children with epilepsy.Thirteen patients (31.7%) had poor efficacy in reduction of seizures,7 patients (17.1%) discontinued LEV monotherapy due to either an inadequate seizure control or aggravated seizures.Fifteen patients (36.6%) had the therapy-related adverse events in LEV monotherapy,including gastrointestinal dysfunction (5 cases),irritability (5 cases),dizziness (2 cases) and somnolence (2 cases).The adverse effects appeared in 2-4 weeks of early LEV therapy and were spontaneously disappeared in 1 week to 1 month of continuing therapy.Conclusions The LEV monotherapy is effective and safe for the control of partial and generalized seizures in children with epilepsy.LEV appears to be a broad-spectrum,first-line anti-epileptic drug in treatment of children with epilepsy.

Objective To investigate whether homocysteine(Hcy) induces apoptosis of endothelial cells via a pathway involving caspases3 and whether simvastatin antagonizes the proapoptotic effects of Hcy by regulating c-IAP. Methods Human umbilical vein endothelial cells(HUVEC) were treated with Hcy,with or without simvastatin,for 24 h.Cell apoptosis was evaluated by Annexin V staining and flow cytometery,as well as TUNEL.The mRNA and protein levels of caspase3,c-IAP-1 and c-IAP-2 were analyzed by RT-PCR and Western blot,respectively. Results Treatment with both low(0.5 mmol/L) and high(3.0 mmol/L) concentrations of Hcy-induced HUVEC apoptosis was accompanied by an increased level of caspase3 expression and activation,together with decreased c-IAP-1 and c-IAP-2 level.Simvastatin upregulated c-IAP-1 and c-IAP-2 expression while attenuated Hcy-induced apoptosis and caspase3 activation. Conclusion Hcy may induce HUVEC apoptosis via a pathway involving caspase3,which can be partially antagonized by simvastatin,possibly through upregulated c-IAP-1 and c-IAP-2 expression.

Objective To compare 99Tcm-MIBI MPI with delayed enhancement MRI (DE-MRI) in patients with idiopathic dilated cardiomyopathy (IDCM). Methods Forty patients with IDCM were included. They underwent both rest 99Tcm-MIBI myocardial perfusion imaging and DE-MRI within 7 days. 99Tcm-MIBI MPI was performed to identify diffuse or segmental abnormal perfusion patterns including reduced or defect perfusion segments. DE-MRI images were divided into 4 categories: no delayed enhancement, septal, subendocardial and transmural delayed enhancement, x2 test was used for data analysis. Results Diffuse and segmental perfusion abnormality on 99Tcm-MIBI MPI were found in 19 (47.5%) and 21 (52.5%)patients respectively, while DE-MRI enhancement was simultaneously found in 5 patients of the former (5/19, 26.3%) and 18 (18/21, 85.7%) of the latter (x2 =14.401, P＜0. 001). For those (n=18) with both segmental perfusion abnormality and DE-MRI enhancement, the number of segments of the 4 DE-MRI respectively. A significant difference was found in the DE-MRI enhancement categories between normal and defect perfusion segments (x2 = 29. 183, P ＜0.001 ) and between reduced and defect perfusion segments as well (x2 =25. 110, P＜0. 001). Conclusions Both diffuse and segmental perfusion abnormalities on 99Tcm-MIBI MPI can be found in patients with IDCM. DE-MRI enhancement is more frequently found in patients with segmental perfusion abnormality.

Objective To evaluate the myocardial blood supply in patients with metabolic syndrome (MS) using 99Tcm-MIBI SPECT MPI. Methods A total of 342 patients were divided into four groups according to the number of abnormal metabolic indices: no abnormal metabolic index (Group 1), one abnormal index (Group 2), two abnormal indices (Group 3), three or more abnormal indices (Group 4). Each patient underwent two-day protocol of gated stress and rest 99Tcm-MIBI MPI. One hundred and three of the 342 patients were clinically diagnosed as MS and underwent CAG within 1 month after MPI. χ2test was used to evaluate the difference among the four groups and Kappa test to analyze the correlation between MPI and CAG. Results Compared with CAG, the diagnostic sensitivity, specificity, positive and negative predictive values by 99Tcm-MIBI SPECT MPI for coronary artery diseases (CAD) in 103 MS patients were 80.5% (33/41), 85.5% (53/62), 78.6% (33/42) and 86.9% (53/61), respectively. The correlation coefficient between MPI and CAG was 0.657 (P<0.001). The abnormal MPI rates in group 1, 2, 3 and 4 were 23.3% (10/43), 32.9% (26/79), 54.4% (56/103), and 57.3% (67/117), respectively (χ2=23.22, P<0.001). Conclusions In MS patients,99Tcm-MIBI SPECT MPI can be useful for evaluating myocardial blood supply and the myocardial ischemia rates may correlate positively with the number of abnormal metabolic indices.

OBJECTIVETo investigate the protect effects of sodium ferulate (SF) on the daunormbicin(DNR-induced cardiotoxicity in juvenile rats.

METHODSForty male juvenile SD rats were randomly divided into control group (Control), daunorubicin group (DNR), sodium ferudate treatment group (DNR + SF), sodium ferudate group (SF) (n = 10) . Juvenile rats were intraperitoneally treated with DNR (2.5 mg/kg every week for a cumulative dose of 10 mg/kg) preparation immature myocardial injury model in presence with SF (60 mg/kg) oral treat- ment for 25 days. The left ventricular pressure and its response to isoproterenol were measured using left ventricular catheter. Rat myocardium myocardial pathology specimens and ultrastructure changes were also observed. The expression of cardiac Troponin I (cTNI) was detected by Western blot and RT-PCR. Results: SF treatment could inhibit the decreasing of heart rates induced by DNR damage (P < 0.05); it could increase the left ventrivular end diastolic pressure(LVEDP), heart rate, the maximal left ventrivular systolic speed(LVP + dp/dtmax) and the maximal left ventrivular diastolic speed (LVP-dp/dtmax) responding to isoproterenol stimulation(P < 0.01); SF also could improve the myocardial ultrastructure injuries and inhibit the decreasing of cTNI expression caused by DNR damages (P < 0.05).

CONCLUSIONSF treatment could alleviate the decreasing of cardiac reservation induced by DNR damages in juvenile rats, which might be related to its reversing the effects on the cardiac systolic and diastolic function injuries and its inhibiting effects on the decreasing of cTNI expression caused by DNR. The mechanism of SF preventing daunorubicin-induced cardiotoxicity in juvenile rats is relevant to inhabited cardiac Troponin I expression.
