Data Envelopment Analysis (DEA) method is used to evaluate the efficiency of 41 tertiary hospitals in 2015 in Beijing.The possible causes of non-DEA effective hospitals are analyzed,and the direction and measures of non-DEA effective hospitals to promote scientific research efficiency are put forward.

Objective To explore Sex differences of total homocysteine(tHcy) levels,and relationship between serum creatinine and homocysteine,and renal regulation to homocysteine in patients with cerebrovascular diseases within normal serum creatinine concentrations. Methods The levels of fasting serum tHcy?Scr?triglyceride(TG)?total cholesterol(TCHO)?high density lipoprotein cholesterol(HDL-C)?high density lipoprotein cholesterol(LDL-C)were determinedin groups of cerebral infarction(CI,278 males and 160 females),cerebral hemorrhage(CH,22 males and 16 females)and transient ischemic attacks(TIAs,27 males and 20 females).The situation that patients along with hypertension and diabetes mellitus were also investigated in three groups. Results Comparison in three groups:the tHcy concentrations were significantly higher in CI than in TIAs(P 0.05). Sex comparison(327 males,196 females,from CI,CH,TIAs):the tHcy concentration were significantly higher in males than females[P

In this paper, the biological compatibilities of FGF/Collagen compound sponges are evaluated. Intracutaneous stimulation test and shortterm muscle embedding test of FGF/Collagen compound sponges made of different materials are performed. Experimental data are analyzed and evaluated according to the standard. The two sponges get marks of 0 in acute eye stimulation test and intracutaneous stimulation test, thus they are not stimulating to tissues. In shortterm muscle embedding test, they don't lead to inflammation reactions and can be degraded and absorbed in short term. FGF/Collagen compound sponge proves good biological compatibility and has a cheerful prospect in medicine.

AIM: Hydroxymethylglutaryl CoA (HMG-CoA) reductase inhibitors, such as simvastatin, have been shown to reduce atherosclerotic cardiovascular morbidity and mortality by mechanisms unrelated to its lipid-lowering effect. Several studies have shown that simvastatin induces apoptosis in a varieties of cell lines including vascular smooth muscle cells (VSMC). The aim of this study was to investigate the signal pathways involved in apoptosis induced by simvastatin. METHODS: Cultured VSMC were treated with simvastatin. Calpain activity was determined by measuring Ca 2+ ionophore-specific calpain substrate (suc-LLVY-AMC), caspase-3 activation was detected by Western blot, and apoptotic changes were distinguished by annexin Ⅴ binding and DNA laddering. RESULTS: After incubated with 30 ?mol/L simvastatin for 8 h, calpain activity had a marked increase ( P

This article summarized the management status of scientific research fund of our hospital. It focused on the whole process management which included the establishment,application and permission of the fund,supervision and tracking of the granted projects.All the management process was dealt with the management mode including standard management,scientific management and tracking management.Some effective experiences were obtained from the whole process management.

Since Peking University People's Hospital Research and Development Funds were founded as "Seed Funds" in 2006, its management concept has been developing. During the development, the policy-oriented service replaced the policy-based single service. The three-dimensional service system was formed. As the result, the scientific research outputs increased annually with good development condition.

OBJECTIVE: To introduce an operation of subscapularis slide from its origin and anterior release from its insertion for treatment of medial rotation contracture, subluxation and dislocation of the shoulder caused by obstetric brachial plexus palsy (OBPP). METHODS: Thirty-six cases with medial rotation contracture of the shoulder were diagnosed by measurement of the inferior glenohumeral angle, passive lateral rotation of the shoulder and plain radiographs. Subscapularis slide was performed in 24 cases with simple medial rotation contracture, and anterior release in 12 cases with complex contracture-medial rotation contracture combined with subluxation, dislocation, or other deformities of the shoulder joint. Systems of Mallet scoring and Gilbert grading for the shoulder were used to evaluate the postoperative shoulder function. RESULTS: With follow up for a minimum of six months, 32 cases got apparent gains from operations, accounting for 88.8% of the total operated on. The younger the child was, the better the result. Of 4 cases with no operative effects, 3 had no flexion of the elbow preoperatively, suggesting a poor recovery of the upper trunk of the brachial plexus; the rest one had no repair of the severed subscapularis tendon. CONCLUSIONS: Subscapularis slide and anterior release of the shoulder are effective for treatment of medial rotation contracture as well as its consequence of subluxation and dislocation of the shoulder in OBPP. The operative effect is related to children's age and the recovery extent of the upper trunk of the brachial plexus.

Objective To investigate the processing characteristics of locative prepositions in patients with Chinese aphasia,and to provide the theoretical evidence for the rehabilitation of aphasia.Methods Twenty aphasic patients caused by left-hemisphere stroke and twenty matched normal controls were studied.Using the locative prepo- sition repeating task(single words,locative preposition phrases and words in sentences),the comprehension task, filling-gap task,the visual-spatial function task and the short-term memory task,we compared the performance be- tween these two groups.Results The aphasic patients had more difficulty in repeating locative prepositions in sen- tences,in comprehension task and filling-gap task,their short term memory was impaired.Both groups did well in re- peating single words and phrases.Conclusion The processing of locative prepositions was impaired in Chinese aphasics.The repetition of locative prepositions was more difficult than that of phrases and single words.The preposi- tions were often omitted.It might be due to the impairment of their short-term memory,or it might have something to do with role they played in the syntactic structure.The latter might also impact the comprehension and filling-gap score.We should make plans before rehabilitation therapy.

The scientific research achievements and possible impact factors were analyzed statistically in the hospital during the past 10 years,especially in 2007,and the analysis result showed the development trends of the scientific research and impact factors of rewards.Also,to improve medical scientific research and its management level,the author proposed the related countermeasures and suggestions in this artiele.
