Objective To investigate the effect of construct the Notch1 (NICD) eukaryotic expression vector on the proliferation and differentiation of rat bone marrow mesenchymal stem cells (BMSCs) in vitro. Methods Rat BMSCs were experimented as the object. NICD eukaryotic expression vector was constructed. pEGFP-N1-NICD expressing plasmids were used to transfect BMSCs. The study included control group (CON group), empty vector group (VEC group) and the trans-fection group (TRA group). After 48-hour transfection, BMSCs were observed for general morphology. The protein expres-sions of NSE, GFAP and Notch1 were detected by real-time PCR and Western blotting assay respectively. The apoptosis, cy-cle distribution and cell proliferation were evaluated by flow cytometry and MTT assay. Results The DNA sequencing con-firmed that the pEGFP-N1-NICD recombinant plasmid was successfully constructed, and both VEC group and TRA group expressed green fluorescence after 48-hour transfection. The relative expression levels of Notch1 and GFAP mRNA and pro-tein were significantly higher in TRA group than those in VEC group and CON group (P<0.05), and there was no significant difference between VEC group and CON group. After 48-hour transfection, the ratio of living cells was significantly lower in TRA group than that of CON group and VEC group, and the early apoptotic rate and late apoptotic rate were significantly higher in TRA group than those of CON group and VEC group (P<0.05). The late apoptotic rate was significantly higher in VEC group than that of CON group. The proportion of G1/G0 cells was significantly higher in TRA group than that of CON group and VEC group, but S and G2/M cells were significantly lower (P<0.05). The value of growth curve was gradually de-creased in TRA group than that of CON group and VEC group (P<0.05). Conclusion The high expression of NICD gene might induce apoptosis of BMSCs, inhibit the proliferation in part, and induce into glial-like cell differentiation.

Objective The purpose of this study was to investigate the correlation of high sensitivity C-reactive protein (hsCRP) and fibrinogen with carotid artery arteriosclerosis of patients with cerebral infarction. Methods One hundred and thirteen patients with cerebral infarction were assigned as study group, and 102 healthy persons as control group. The levels of serum hsCRP and Fib in the two groups were measured. The carotid artery arteriosclerosis and carotid intimal-medial thickness (IMT) were examined by color Doppler and B-ultrasound. Results The value of IMT between study group and control group was statistically significant. The positive rates of carotid artery arteriosclerosis plaque and vulnerable plaque in study group were significantly higher than those in control group (all<0.05) . The level of serum hsCRP was significantly higher in study group than that of control ( <0.05) . The level of serum Fib between study group and control group was not statistically significant ( >0.05) . Conclusion The level of hsCRP was closely related to the degree of carotid artery arteriosclerosis and the occurrence and development of cerebral infarction. But the level of Fib was not closely related to the degree of carotid artery arteriosclerosis.

Objective To assess the efficacy of mycophenolate mofetil (MMF) combined with prednisone in the treatment of idiopathic membranous nephropathy (IMN) patients with positive serum phospholipase A2 receptor (PLA2R) antibody.Methods An open prospective study was performed on twenty-four biopsy-proven IMN patients with positive serum PLA2R antibody in Guangzhou First People''s Hospital from June 2012 to June 2016.The 24 patients were divided into two groups: MMF group in which MMF combined with prednisone was given for 12 months and CTX group in which intravenous cyclophosphamide (CTX) was monthly given combined with oral prednisone.Results After 6 months of immunosuppressive therapy,complete remission and partial remission rates were 25.0% vs.16.7% and 25.0% vs.25.0% in the MMF group and CTX group,respectively (P>0.05).In the MMF group and CTX group,serum PLA2R antibody in the same amount (8/12,66.7%) of patients turned negative.At the end of twelve-month treatment,all patients with negative PLA2R antibodies achieved complete or partial remission.Clinical remission (including complete and partial remission) rates in the MMF group and CTX group were both 66.7%.After immunosuppressive therapy,the levels of proteinuria and serum albumin in the two groups were significantly improved,but no significant difference were found between the two groups (proteinuria:F within-grouP=98.688,P<0.01;F between-grouP=0.133,P=0.719;F cross-grouP=1.223,P=0.304;serum albumin:F within-grouP=30.629,P<0.01;F between-grouP=0.137,P=0.715;F cros-grouP=0.455,P=0.565).At the end of six and twelve months of treatment,the proteinuria (after six months,MMF group: (2 893±2 515) mg/g vs.(6 236±2 117) mg/g,t=-3.522,P=0.002;CTX group: (2 690±2 254) mg/g vs.(5 386±2 447) mg/g,t=-2.808,P=0.010;after twelve months,MMF group:1 025(99-4 635) mg/g vs.(6 236±2 117) mg/g,Z=-3.291,P<0.0005;CTX group: (775(41-3 517) mg/g vs.(5 386±2 447) mg/g,Z=-3.118,P=0.001) and serum albumin levels (after six months,MMF group: (28.5±9.7) g/L vs.(19.8±4.4) g/L,t=2.841,P=0.012;CTX group: (29.0±7.6) g/L vs.(22.3±4.1) g/L,t=2.690,P=0.016;at the end of twelve months of treatment,,MMF group: (32.4±8.5) g/L vs.(19.8±4.4) g/L,t=4.570,P<0.0005;TX group: (32.2±7.9) g/L vs.(22.3±4.1) g/L,t=3.862,P=0.001) of the two groups were better than those prior to treatment.Conclusion For the IMN patients with positive serum PLA2R antibody,MMF combined with prednisone was as effective as conventional CTX combined with prednisone in the negative conversion of PLA2R antibody and the remission.The negative conversion of PLA2R antibody after 6 months of immunosuppressive treatment was an important indicator of predicting the remission.

Objective To investigate the efficacy and safety of clopidogrel hydrogen sulfate plus nimodipine in treating transient cerebral ischemic attack.Methods A total of 159 outpatients and inpatients with transient cerebral ischemic attack in the neurosurgery department and the neurology outpatient department of our hospital from January 1,2012 to September 1,2016 were divided into 3 groups.The group A(43 cases) orally took clopidogrel hydrogen sulfate plus aspirin;the group B (51 cases) treated with oral clopidogrel hydrogen sulfate plus nimodipine;the group C(65 cases) was treated with clopidogrel hydrogen sulfate plus nimotop.The curative effects were observed in 3 groups.The differences of PT.APTT,FIB and PLT in 3 groups were compared between before and after treatment.Results The total effective rate of the group A and C was significantly better than that of the group B(P<0.05),the curative effect had no statistical difference between the group A and C (P>0.05);the effect of the group B and group C on coagulation was superior to that of the group A(P<0.05).The three group had no severe bleeding events(cerebral bleeding,etc.),the difference was statistically significant.Conclusion Clopidogrel hydrogen sulfate combined with nimotop can significantly reduce the frequency of transient cerebral ischemic attack,has little influence on the coagulation indicators,and is safe and effective.

Objective To analyze the status of supply and the affected factors of the home care of the elderly in community of Shenzhen.Methods The investigation was carried out in 78 community health ser-vice centers and 216 elderly from 6 communities using self-designed questionnaire.Results 84% of the el-derly had the demand of home care, 38.1% of them had even received home care services.In 32 demand items of home care, the top 6 were in turn the blood pressure monitoring, the blood sugar monitoring, the health consults, the caregivers guidance, the psychological care, medication instruction.48 of 78 commu-nity health service center provided door-to-door services, 44% of them(home care service center)provided more than 10 projects, 67% of the center provided more than 5 projects, 17% of them provided 2 projects, 30 community health service center did not provide door-to-door service.The main reasons that influenced home care delivery in community were the shortage of nursing staff of home medical care, the risk factors, the medical environment, and the limited health care facilities.Conclusions The elderly has large de-mand to the home care service, home care which the community health center provided is lagging and in short supply.It is imperative to increase the number of community nurses, improve the community home care profession standard and promote stable development of home care.
