Objective In order to provide a large quantity of retinal pigment epithelial cells (RPE cells) in vitro, we want to estab-lish method for culturing pig RPE cells. Methods RPE cells were separated with trypsin and cultured in vitro. The cells were identified by immunohistochemical staining with anti-human keratin and transmission electron microscope (TEM). Results Cultured RPE cells gradually presented transparent and fusiform shape. Immunohistochemical staining demonstrated that the cells were stained by anti-human keratin, and the cultured cells showed typical ultrastructure of RPE cells. Conclusion The cultured cells may be the foundation of pig RPE cells.

Objective: To provide policy recommendations for improving price negotiation system of patented drugs in China. Methods: This paper comparatively analyzes the commonalities and characteristics between Korea’ and Germany’s price negotiation models for patented drugs from three aspects of their goals, procedures and effects. Results:The key objective of both Korea’ and Germany’s price negotiation systems for patented drugs is to efficiently improve the utilization of national health insurance services, and responsibilities are properly assigned among differ-ent institutions to ensure the equity and efficiency of negotiations. However, due to the differences in national cir-cumstances, there is a big difference in the selection of technical assessment criteria. Conclusion: This paper sug-gests China to strengthen the convergence between price negotiations for patented drugs and medical insurance reim-bursement policy, to establish a technical assessment system with the innovation extent for patented drugs as its core, and to develop scientific and rational negotiation procedures and division of responsibilities as well.

OBJECTIVE:To evaluate the application effects of PDCA cycle management in the outpatient prescription intervention.METHODS:A total of outpatient prescriptions (pre-intervention group) during Jan.-Dec.2014 and 918 659 (intervention group) were selected during Jan.-Dec.2015 were selected from a hospital.Irrational 9utpatient prescriptions were analyzed before and after the application of PDCA cycle management,and the improvement of main indexes were compared such as unsuitable usage and dosage,incomplete clinical diagnosis writing,no physicians' signature on the prescription or inconsistent with sample.RE SULTS:Before intervention,there were 2 347 irrational prescriptions,including 1 401 nonstandard prescriptions,849 unsuitable prescriptions and 97 abnormal prescriptions.After intervention,there were 1 161 irrational prescriptions,including 695 nonstandard prescriptions,425 unsuitable prescription and 41 abnormal prescriptions,decreasing 50.53％,50.39％ 49.94％ and 57.73％,respectively.The proportion of unsuitable usage and dosage,incomplete clinical diagnosis writing,no physicians' signature on the prescription or inconsistent with sample,nonstandard prescription paper,unsuitable indications,no signature and date for prescription revision or no reason and new signature for overdose use,outpatient prescriptions more than 7 d common dose or emergency prescriptions more than 3 d common dose without special situation in total amount of outpatient prescriptions decreased from 0.72‰,0.57‰,0.45‰,0.27‰,0.20‰,0.19‰ and 0.15‰ before intervention to 0.32‰,0.25‰,0.19‰,0.11‰,0.09‰,0.08‰ and 0.07‰ after intervention.CONCLUSIONS:PDCA cycle management significantly improves the quality of outpatient prescriptions.There still are irrational outpatient prescriptions in this hospital,and it is to be intervened continuously.

OBJECTIVE:To prepare a Chinese medicinal agent for external application on burn wounds.METHODS:To establish the formula,preparation technic and quality control standard of burn oil solutions I and to observe the therapetuic effect.RESULTS:The preparation technic was feasible and method of quality control simple.The mean recovery was 99.68%(N=5),RSD=0.80%.Burn wounds

AIM To explore the effect of ACE inhibitor on early kidney hypertrophy and its mechanism in diabetic rats. METHODS Rats were randomly divided into three groups: uninephrectomized rats, streptozotocin induced diabetic rats and diabetic rats treated with benazepril (an ACE inhibitor, 10 mg?kg -1 ?d -1 , ig). Activity of ACE was determined by the fluorimetric assay. Expression of TGF? 1 mRNA and TGF? 1 and p21 CIP1 protein was measured by Northern blot analysis and Western blot analysis, respectively. RESULTS After 1 week, the diabetic rats developed a body weight loss, kidney weight/body weight increased and renal cortex ACE activity elevated despite a decrease in plasma ACE activity. Northern blot analysis showed that renal cortex TGF? 1 mRNA expression in the diabetic rats was enhanced by 1.3 times, compared with uninephrectomized rats. Western blot analysis showed that TGF? 1 and p21 CIP1 protein expression were also increased. Administration of benazepril for one week significantly suppressed kidney hypertrophy. ACE activity in the plasma, renal cortex and medulla was reduced by 89%,70% and 70 5%, respectively. Expression of TGF? 1 mRNA as well as expression of TGF? 1 and p21 CIP1 protein was reduced by 47 7%, 49 5% and 60 0%, respectively. CONCLUSION Our results suggest that the suppression of ACE inhibitor on diabetic kidney hypertrophy might partially be associated with a decrease in the expression of TGF? 1 and p21 CIP1 in diabetic rats renal cortex. However, its exact mechanism remains to be further explored.

Objective To study the superiority and safety of cup-shaped womb manipulator auxiliary peritoneoscope in entire womb excision. Methods 180 cases with hysterectomy were randomly divided into cup-shaped womb manipulator auxiliary peritoneoscope group(treatment group) and tradition into the abdominal group( control group) ,and the amount of bleeding and postoperative complications,and patient recovery were observed in the two groups. Results Compared with the control group, the quality of life of patients with anal exhaust time, average length of staying, postoperative recovery daily time were significantly improved, and there were statistically significant differences between two groups ( P ＜ 0. 05 ). There was no serious complication in the two groups. Conclusion Cup-shaped womb manipulator auxiliary peritoneoscope hysterectomy was a safe and feasible operation,and could relieve harm and improve patients quality of life.

This review snmmarized and estimated the management of cataract blindness in China recently,and introduced the purport of clinic medical economics.Based on it,it was proposed that our service system of cataract blindness could use the experiences of other countries as reference and engaged in more investigations in search of Chinese way for cataract blindness.

Objective To evaluate the feasibility of combined application of helicobacter pylori stool antigen(HpSA)-and traditional serology in epidemiologic study of helicobacter pylori(Hp) infection in children. Methods Hp serum IgG antibodies were examined among 480 healthy children. Heticobacter pylori stool antigen(HpSA) were measured among children who were seropositive. Hp status was defined as positive when stool antigen test was positive, Hp status was defined as negative when seronegative. A case - control study was conducted to identify risk factors of Hp infection in preschool children. Results Among 480 preschool children, 172 (35 8 %) were sero- positive, 64(13.3 %) with positive result of HpSA test were diagnosed as current Hp infection. Univariate factor analysis demonstrated that Hp infection clustered in families and Hp infection was often acquired in childhood by oral-oral and fecal - oral person to person transmission. Conclusions HpSA and serology screening are two nomnvasive tests, simple not costly, effective and accurate. The combination of these 2 noninvasive methods can be applied in epidemiologic study of Hp infection in childrenJAppl Clin Pediatr,2004,19(11):948-950
