Objective To clarify whether the intravenous administration of embryonic stem cells(ESCs)could home in on injured myocardium caused by acute myocardial infarction(MI)in rats and to improve the cardiac function afterwards,and to explore the possible effect of inflammatory factor TNF-?on it.Methods ESCs were cultured in vitro and transfected with green fluorescence protein(GFP).The model of heart failure post MI in rats was established by permanent ligation of left coronary anterior descend artery.After operation the rats were administered with 10~7 ESC via tail vein every other day for 6 days.The sham and MI without ESCs infusion groups served as control.Six weeks later,the hemodynamic measurement was employed to evaluate the cardiac function.Immunohistochemistry assay was used to detect the GFP expression in heart and other organs,and the cardiac specific protein Tropinin I(Tn I)expression in GFP positive spot of heart.Meanwhile,the co-culture in vitro of ESC and neonatal rat cardiomyocytes was used to observe the effect of overexpression of TNF-?in cardiomyocytes on ESC migration.Results Six weeks after MI,cardiac function was significantly improved in rats administered with ESC in comparison with those of MI group.Histological changes demonstrated that infused ESCs formed GFP-positive grafts in infracted myocardium.Alternatively,the positive immunostaining for Tn I was found in the area corresponding to GRP positive staining.In regard to other organs,only in spleen a few GFP positive cells were found.This would indicate that circulating ESC could translocate to infracted myocardium and to form cardiac tissue.Migration assay of ESC in vitro indicated that cultured cardiomyocytes with overexpression of TNF-aobviously enhanced the migration of ESCs in comparison with cardiomyocytes without transfection. Conclusion Intravenously infused ESC could home in on infarcted myocurdium and futher differentiate into cardiomyocytes which led to the improvement of cardiac function.In the setting of acute MI the homing mechanism Could be associated with locally released inflammatory factors such as TNF-?which may play as a chemotactic agent on circulating ESC.

AIM: To analyze the effect of preoperative intravitreal injection of Ranibizumab ( lVR ) in patients undergoing pars plana vitrectomy ( PPV ) for proliferative diabetic retinopathy ( PDR) .
●METHODS:ln this retrospective research, 62 patients (67 eyes ) with PDR in the First Affiliated Hospital of Xinjiang Medical University from Jun. 2014 to Jun. 2015 were recruited. They were assigned to an experimental group ( n=37 eyes ) and a control group ( n=30 eyes ) . The patients in experimental group were given 1 injection of lVR ( Lucentis 1. 0mg/0. 1mL ) 1wk before surgery, whereas those in control group went down to surgery directly. The average operation time, iatrogenic breaks, the use of tamponade, electric coagulation, and vision increase rate were comparatively analyzed between two groups.
●RESULTS:The average operation time was (91. 7±20. 8) min in the experimental group vs (117. 6±18. 6)min in the PPV group(t = -5. 314,P<0. 05). The rate of electric coagulation (11%) vs (47%), (χ2 =8. 963, P=0. 006);iatrogenic breaks (5%) vs (33%), (χ2=8. 789, P=0. 004) and silicone oil or inert gas tamponade ( 27. 0%) vs (53. 3%), (χ2 = 4. 828, P = 0. 043 ). The rate of visual improvement (75. 7%) vs (46. 7%), (χ2 = 5. 960, P =0. 022 ) . There was no severe complication associated with surgery, such as choroidal detachment, retinal detachment and endophthalmitis.
●CONCLUSION:lVR before microincision vitrectomy can effectively shorten the operation time, reduce the use of electric coagulation and intraocular tamponade, and improve the rate of visual improvement for PDR patients.

OBJECTIVETo observe the clinical efficacy of comprehensive Western medical treatment plus Compound Yindan Decoction (CYD) in treatment of acute cholestatic hepatitis (ACH).

METHODSUsing randomized controlled study, 60 ACH patients in line with inclusive criteria were randomly assigned to the treatment group (treated by comprehensive Western medical treatment plus CYD) and the control group (treated by comprehensive Western medical treatment alone), 30 in each group. Scores for symptoms and levels of liver functions [total bilirubin (TBIL), direct bilirubin (DBIL), alkaline phosphatase (ALP), glutamyl transpeptidase (GGT), total biliary acid (TBA)] were observed before and after treatment.

RESULTSCompared with before treatment in the same group, total scores for symptoms decreased in the treatment group and the control group at the end of the 1st and the 4th week after treatment (all P < 0.05). Compared with the control group, total scores for symptoms decreased in the treatment group at the end of the 1st week (P < 0.05). Compared with before treatment, serum levels of TBIL, DBIL, ALP, GGT, and TBA all decreased in the two groups at the end of the 4th week after treat- ment (P < 0.01). Compared with the control group, serum levels of TBIL, DBIL, ALP, GGT, and TBA all decreased in the treatment group at the end of the 1st and the 2nd week after treatment (P < 0.05). Compared with the control group, the average time for TBIL and DBIL decreasing to the level less than five times the normal value was significantly shorter in the treatment group (P < 0.05).

CONCLUSIONCYD could significantly improve clinical symptoms of ACH patients, decrease serum levels of TBIL and DBIL, reduce serum levels of ALP, GGT, and TBA, obviously improve cholestasis, and promote the recovery.
