Trial was made on a new way of administering drugs topically for eye conditions using a collagen corneal shield to deliver the agents. A 4mm perforating incision was made at the center of the rabbit's cornea. Thirty rabbits were used which were devided at random into 3 groups. The first group served as control, the second group was given basic fibroblastic growth factor (bFGF) as eyedrops, and the third groedup collgsu aen shields which had been soaked in bFGF. After 8 days, the maximum pressures that the corneas could stand were significantly different among the 3 groups (p

Objective: Our aim was to investigate the relationship between tumor doubling time (TD) and the prognosis of patients with lung cancer.Methods:According to the diameter of tumor or its shadow,the TD of tumor was calculated and postoperative survival time (PST) were predicted based on the Geddes' nomogram.The statistic analysis was performed after comparison with the actual survival time (AST).Results:There was no significant difference of TD among tumors of different histological types (P>0.05).The accumulated survival in patients with TD>100 days was higher than those with TD<100 days, with a significant difference (P<0.05).The AST in patients underwent surgery was markedly higher than the PST,indicating that the operation was effective.Conclusion:Tumor TD may be a valuable parameter for evaluating the prognosis and surgical treatment in patients with lung cancer.

Objective:To discuss the effect of transitional care on the quality of life ( QOL) and psychology in acute myocardial infarction patients after PCI. Methods:The acute myocardial infarction patients accepted PCI in our university affiliated hospitals were selected and divided into experimental group and control group randomly. The control group received routine care during the period of hospitalization. The experimental group received transi-tional care including home visits, massed learning, telephone follow-up, and the establishment of WeChat and QQ group. The QOL, anxiety, and depression were investigated pre-intervention and six months post-interven-tion to evaluate the effect of transitional care. Results:After transitional care six months later, the QOL scores in the experimental group were significantly higher than those in the control group, SAS and SDS scores were lower in experimental group than those in the control group ( P<0 . 05 ) . Conclusions:Transitional care for acute myocar-dial infarction patients after PCI could improve their QOL, and relieve their anxiety and depression level in different degrees.

Objective To investigate efficacy in Alpmstadil and Shenkang on regulating renal function and lipids in patients with chronic renal failure (CRF).Methods Ninety-eight cases of CRF patients were collected for the study,and 1:1 randomized,double-blind experiment grouping principles were used in the current study.All cases were divided into study group and the control group (49 cases of each group).The two group were given the high quality low protein,low fat low salt diet,inftion control,diuretic swelling,correct acidosis,buck,correction of electrolyte imbalance and other conventional treatment.The patients in study group on the basis of conventional therapy were given 20 g Alprostadil injection + 100 ml saline,intravenous infusion of 1times/d,and 100 ml Shenkang injection +300 ml 5％ glucose the solution,intravenous infusion of 1 times/d.While patients of control grrup on the basis of conventional therapy plus 200 mg Ligustrazine + 250 ml 5％Glucose Injection,intravenous infusion of 1times/d.Two groups were treated for 14 d.Before and after treatment,renal function,lipid metabolism,adverse drug reactions were observed and determined.Results There was no significant difference in term of renal function between two groups before treatment(P ＞ 0.05).After treatment,the levels of serum creatinine,blood urea nitrogen,24 h-Urine protein and creatinine clearance(Ccr) in study group were (313.7 ±66.2) mmol/L,(15.3 ±2.9) mmol/L,(1.24 ±0.45) g/24 h and (35.7 ±5.4) mmol/L respectively,significant different from those in control group ((358.4 ± 53.9) mmol/L,(18.4 ± 3.0) mmol/L,(1.57 ±0.39) g/24 h and (28.4 ±4.3) mmol/L;t =3.754,7.864,5.873,4.312,P ＜0.05).There was no significant difference in term of blood fat between two groups before treatment (P ＞ 0.05).In study group,the levels of glycerin trilaurate,cholesterol total,high density hpoprotein cholesterol,low density lipoprotein cholesterol were significantly different than those in the control group ((2.12 ± 1.26) mmol/L vs.(2.32 ± 1.34) mmol/L,(4.91 ± 1.43) mmol/vs.(5.35 ± 1.31) mmol/L,(1.39 ± 0.43) mmol/L vs.(1.23±0.37) mmol/L,(2.39 ± 0.68) mmol/L vs.(2.73 ± 0.88) mmol/L; t =3.876,4.661,5.387,8.543 ; P ＜ 0.05) after treatment.There were no adverse drug reactions in both groups.Conclusion Combined usage of alprostadil and shenkang injection could significantly improve the patient's renal function,lipid metabolism disorders and shows no significant adverse reactions,suggesting that it is worthy of clinical application and promotion.

Objective To investigate the level of disaster nursing ability and cognitive status of nursing manager,explore the characteristics and influencing factors,in order to provide a basis for intervention in improving the capacity of disaster nursing care.Methods 113 nursing managers were recruited by convenience sampling from a first-class ternary hospitals in Anhui province.They were investigated by a self-designed demographic data questionnair and disaster nursing and cognitive scale.Results The score of the disaster nursing ability of the nursing managers was 114.12±18.21,the mean score was 2.65±0.42,both below the medium level.Regression analysis showed that the nursing age of nurse manager,whether accepted disaster nursing training after work were the influencing factors of the disaster nursing ability of the nursing managers and explained 33.5％ of the variance.Conclusions The capacity of disaster nursing care of nurse managers is not high.The nursing age of nurse manager,whether accepted disaster nursing training after work were the influencing factors of the disaster nursing ability of the nursing managers.

The diagnosis of post-concussion symptoms (PCS) has been a controversial issue because of that its pathogenesis is often involved in both neural damage and psychosocial factors. Recent researches have examined the diagnostic and evaluating value of several available methods or tools, including clinical interview, conventional CT and magnetic resonance imaging (MRI), neuropsychologic testing and neurochemical test. In mild traumatic brain injury (MTBI), there exist diffusive damages to white matter distributed particularly near the gray matter-white matter boundary and in the long white-matter tracts in midline structures. The conventional imaging techniques are unable to detect any positive evidence due to the diffusive nature of these injuries. This paper is to review epidemiologic study, diagnostic criteria and relevant disputes, conventional diagnostic strategy and new MRI techniques, and then evaluate the application and prospective value of them in the diagnosis and rating of PCS and MTBI. Non-invasively quantitative assessments of modern brain imaging technique may be developed to sensitive and promising tools in the diagnosis and forensic evaluation of PCS.

Apolipoprotein M-sphingosine-1-phosphate axis ( apoM-S1P axis ) signaling pathway consists of apolipoproteinM (apoM), sphingosine-1-phosphate (S1P) and sphingosine-1-phosphate receptor (S1PR).Plasma apoM belongs to lipocalinsuperfamily members , and is mainly associated to high density lipoprotein( HDL), whereas HDL-cholesterol correlates inversely with cardiovascular risk .The ability of apoM to bind S1P is due to a lipophilic binding pocket within the lipocalin structure of the apoM molecule . S1P, a bioactive mediator of phospholipid metabolism , predominantly abound in HDL among all lipoproteins.S1P can not only be used as intracellular second messengers , but also as intercellular signal molecules, activating of G protein-coupled receptors (S1PR) to mediate various physiological functions.It′s clear that apoM protects human beings from atherosclerosis .Furthermore, recent studies showed that S1P has a significant impact on atherosclerosis , and ApoM-S1P axis may play a important role in the pathogenesis or progression of atherosclerosis .
