Objective: To study the cognitive function of patients with myasthenia gravis.Methods: Cognitive function of 35 patients with general myasthenia gravis and 31 patients with Eye-Muscles myasthenia gravis,and 35 control subjects was examined with cognitive measures of Recall of Auditory Verbal Learning Test,Symbol Digit Modalities Test,Trail Making Test,Logic Memory Test,Stroop Color Words Test(A、B 、C),Verbal fluency Test and Boston Naming Test.Results: MG patients performed worse than the control subjects on several cognitive measures.Conclusion: There is disorder of cognitive function in the patients with myasthenia gravis,revealing that there may exist deficiency in the central neuroal system of the patients with myasthenia gravis.

Objective\ To evaluate the efficacy of atrial lead implantation during atrial fibrillation.Methods\ In 10 patients(group A),the atrial leads were implanted during atrial fibrillation and the sensing and pacing parameters before and after restoring to sinus rhythm were compared with the parameters of patients whose atrial leads were implanted during sinus rhythm (group B).Results\ During follow-up,the sensing and pacing parameters were measured,and there were no significant difference between group A and B.In group A,mean atrial potential amplitude during atrial fibrillation was correlated with the telemetered atrial potential amplitude during sinus rhythm.Conclusion\ Atrial lead implantation during atrial fibrillation is feasible.

Objective To explore the application effect of the wechat public platform in follow-up management of patients with moderate or severe craniocerebral injury.Methods 98 patients admitted in the craniocerebral department of our hospital from February to November 2014 were selected and divided into two groups by random number table method,with 48 cases in the control group and 50 cases in the observation group;the traditional follow-up management mode using telephone was adopted to patients in the control group,while the follow-up management mode using the wechat public platform was adopted to those in the observation group,with a follow-up period of 3 months;for patients in both groups,their activities of daily living (ADL) and exercise of self-care agency (ESCA) abilities before and after intervention,occurrence of adverse events and complications within the follow-up period,and their degree of satisfaction towards the follow-up management were collected.Results After intervention,ADL score,total scores of ESCA and total scores of satisfaction towards the follow-up management among patients in the observation group were 87.34±15.26,24.36±17.24 and 86.07±14.82,which were significantly higher than that among patients in the control group were 66.72±14.62,99.37±15.29 and 61.14±13.19 (t=7.941,7.982,6.962,all P ＜0.01);within intervention,the observation group had significantly lower total occurrence rate of adverse events and complications which was16.00％ (8/50) compared to the control group 39.58％ (19/48) (x2=6.824,P ＜ 0.01).Conclusions By establishing the follow-up management mode for patients with craniocrerbral injury through the wechat public platform,effect of the follow-up management can be effectively promoted,prognosis of patients can be improved and patients' degree of satisfaction can be enhanced;it is worth of being further promoted clinically.

The angiotensinogen(AGT) expression and angiotensin Ⅱ (AngⅡ ) secretion levels in cultured SD rat mesangial cells were determined. High glucose up-regulated AGT mRNA(0. 29±0.07 vs 0. 20±0. 05,P< 0.05)and protein(0.66±0.23 vs 0.37±0. 15,P<0.05) expression and Ang Ⅱ secretion [(9.85±2.08 vs 7.50± 1. 51) pg/ml,P<0. 05]levels, which were down-regulated by pyrrolidine dithiocarbamate( PDTC) treatment via inhibiting NF-κB activity.

Objective To explore the in vitro isolation of ?2m-/Thy-1+ bone marrow-derived liver stem cells(BDLSCs) which bear double features of stem and liver cells from bone marrow stem cells(BMSCs)as so to provide suitable donor cells for the treatment of liver diseases by cellular transplant. Methods ?2m-/Thy-1+ BDLSCs were isolated by magnetic bead cell sorting(MACS) method from cholestatic rats in vitro,and cell purity was detected using flow cytometry.Liver associated phenotype markers were characterized by RT-PCR and immunofluorescence staining. Results BDLSCs isolated by MACS were purified and viable,and possessed hepatocyte-like features at gene and protein levels. Conclusion ?2m-/Thy-1+ BDLSCs are special subsets of BMSCs which may have promising potentials in the stem cell-based treatment of liver diseases.

Objective To identify the isolated rat bone marrow derived mesenchymal stem cells(MSCs),and evaluate the efficiency of adenoviral vector expressing human urokinase type plasminogen activator(uPA) in transfection of rat MSCs and its effect on proliferation of MSCs. Methods MSCs were isolated and purified by pasted wall purification,and were identified by immunicytochemistry.The transfection efficiency of uPA was detected by fluorescent microscopy,the expression of uPA in MSCs was detected by Western blotting,and the proliferation of MSCs was evaluated by MTT. Results The harvested MSCs exhibited the typical appearance of MSCs,and it was revealed by immunohistochemistry that the expression of MSCs markers CD29 and CD90 was positive,while that of CD34 and CD45 was negative.A tendency of increase in expression of green fluorescent protein(GFP) was observed with increase of multiplicity of infection(MOI).After transfection with AduPA for 72 h,the transfection efficiency reached(94.0?1.5)% at MOI of 80,and positive GFP cells could still be observed even after 7 d.The transfected uPA had no effect on the proliferation of MSCs. Conclusion MSCs are favourable genetic vectors to express uPA,and can be used for treatment of liver fibrosis.

Objective To investigate the percentage of CD4 + C125 +Tregs in peripheral blood of patients with sepsis and its effect on cell immunity so as to unravel the effect of immunomodulatory therapy on it. Method Fourty patients with sepsis in ICU were randomly (random number) divided into experimental group and control group . The patients of experimental group were treated with Ulinastatin and immunoregulation agent (Thymosin αl) as well. The blood specimens were collected just before treatment, 3 days and 8 days after treatment. The percentages of CD4 + CD25 + Tregs and lymphocyte subsets were detected by using FCM (flow cytometry), and TNF-α, IL-6 and IL-10 assayed by using ELISA, and APACHE Ⅱ scores were calculated. Results Before treatment, the percentage of CD4 + CD25 + Tregs increased, and the number of lymphocytes and the percentage of T lymphocytes decreased, especially the CD4 + T lymphocytes and CD4+/CD8+ decreased more markedly, and the levels of IL-6 and TNF-α increased. After treatment,the percentage of CD4+ CD25 + Tregs was decreased, the number of lymphocytes and CD4 +/CD8 + increased, and the levels of APACHE Ⅱ score, IL-6 and TNF-α decreased especially in the experimental group decreased more significantly (P ＜ 0. 05). Conclusions The percentage of CD4 + CD25+ Tregs in peripheral blood can reflect the immune status of patients with sepsis and become a novel indicator to estimate the progress of sepsis, and the immunity and prognosis of patients. Treating the patients with Thymosin αl and Ulinastatin can raise their immunity, decrease the levels of IL-6, TNF-α and APACHE Ⅱ score and improve their prognosis.
