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.

The regulatory region and the signal peptide sequence of the sacB gene has been amplified by PCR using Bacillus subtilis chromosomal DNA as template, and an inducible secretion vector has been developed based on this sequence, which was ligated with Bacillus subtilis alkaline proteinase gene. Transform Bacillus subtilis DB403 with this vector, and the expression of the inserted Bacillus subtilis alkaline proteinase gene can be induced by addition of sucrose into the medium.

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 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.

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.
