Objective Different methods were used for the analysis of different medical and health institutions in Henan Province in 2012 of hospital bed utilization,to find bed utilization problems,and provide reference for the rational allocation of resources.Methods Static beds utilization model method (SBMA)and the method of rank sum ratio(RSR)were used for planning of data in“2012 health statistics yearbook of Henan province”,for comprehensive analysis of bed utilization efficiency.Results Among the medical and health institutions in Henan province in 2012,general hospitals,maternal and children hospitals(centers)are found with higher utilization of hospital beds,while other institutions (nursing homes),community health service centers(stations)are found lower.Conclusion Henan Province in 2012 was found on the whole with efficient utilization of hospital beds,yet with rooms of improvement for different medical institutions,especially those at the primary level.

The pathological changes in myocardial cell of diabetic rats were consistent with diabetic cardiomyopathy. The levels of adiponectin and the expression of T-cadherin in diabetic group were increased gradually,and higher than in normal control group

Objective Neurodegenerative diseases, such as ischemia, traumatic injury, Alzheimer's disease, and Parkinson's disease are characterized by neuronal loss and dysfunction. It is known that glutamate-induced toxicity plays an important role in neurodegenerative diseases. Glutamate toxicity seems to be mediated by excessive influx of Ca2+ into neuronal cells through activation of N-methyl-D-aspartate (NMDA) receptor. To search for potential NMDA receptor inhibitors in traditional Chinese medicine. Methods A series of computer methods including drug-likeness evaluation, ADMET tests as well as molecular docking have been used. Results 1,5-O-dicaffeoyl-quinic acid was identified as NMDA receptor inhibitor by virtual screening. Its neuroprotective activity was further confirmed by in vitro test. 1,5-O-dicaffeoyl-quinic acid showed strong neuroprotection against NMDA-induced cell injury. Conclusion 1,5-O-Dicaffeoylquinic acid may be regarded as a potential NMDA receptor inhibitor for the prevention and treatment of neurodegenerative disorders.

Objective To analyze and compare the Eucommia ulmoides leaves from different producing areas by IR;To establish a TLC method for identification of Eucommia ulmoides leaves;To provide a reference for its quality control. Methods The characteristic absorption peaks were identified and the positions and intensities of Eucommia ulmoides leaves from 6 producing areas were compared by IR and second derivative spectrum, including clustering analysis; Separation and identification of the active components in Eucommia ulmoides leaves were conducted by TLC. Results There a difference exited in the characteristic absorption peaks in peakshapes, positions and intensities. And the samples from 6 producing areas could be divided into one category. Results found 6 batches of sample spots of consistent by TLC, but between samples of different producing areas trace components spots existed differences. Conclusion The two methods are direct, simple, fast and convenient, which can provide a reliable evidence for identification and quality control of the Eucommia ulmoides leaves.

To investigate the effect of prostaglandin E_1 (PGE_1) on the liver function following laparotomy, 55 adult patients with normal liver function, undergoing elective laparotomy for gastric cancer under total intravenous anesthesia ,were randomly allocated to receiving intravenous infusion of PGE_1 at rate of 20 to 60ng?kg~(-1). min~(-1)(group PGE_(1,n)=27), or normal saline (group control, n=28 )from the opening of abdomen to the end of operation,respectively. The serum concentrations of glutamin-pyruvic transaminase (GPT)and glutamic-oxaloacetic transaminase (GOT)were measured postoperatively. The results showed that as compared with the values before the operation,the levels of GPT and GOT increased significantly in both groups on the first postoperative day (P

Objective To observe the influence of down-regulation of HtrA1 expression by small interfering RNA on light-injured human retinal pigment epithelium (RPE) cells.Methods Cultured human RPE cells(8th-12th generations)were exposed to the blue light at the intensity of (2000 ± 500) Lux for 6 hours to establish the light injured model.Light injured cells were divided into HtrA1 siRNA group,negative control group and blank control group.HtrA1 siRNA group and negative control group were transfected with HtrA1 siRNA and control siRNA respectively.The proliferation of cells was assayed by CCK-8 method.Transwell test was used to detect the invasion ability of these three groups.Flow cytometry was used to detect the cell cycle and apoptosis.The expression of HtrA1 and vascular endothelial growth factor (VEGF)-A was detected by real time-polymerase chain reaction and Western blot respectively.Results The mRNA and protein level of HtrA1 in the light injured cells increased significantly compared to that in normal RPE cells (t=17.62,15.09;P＜0.05).Compared with negative control group and blank control group,the knockdown of HtrA1 in HtrA1 siRNA group was associated with reduced cellular proliferation (t=6.37,4.52),migration (t =9.56,12.13),apoptosis (t =23.37,29.08) and decreased mRNA (t=17.36,11.32,7.29,4.05) and protein levels (t=12.02,15.28,4.98,6.24) of HtrA1 and VEGF-A.Cells of HtrA1 siRNA group mainly remained in G0/G1 phase,the difference was statistically significant (t=6.24,4.93;P ＜0.05).Conclusion Knockdown of HtrA1 gene may reduce the proliferation,migration capability and apoptosis of light-injured RPE cells,and decrease the expression of VEGF-A.

In order to understand the research status of HUANG Fu-mi's A-B Classic of Acupuncture and Moxibustion, 83 pieces of literature that have been publically published since 1978 were analyzed. A summary was performed according to 7 aspects including version origin, emendation, arrangement and summary, theory discussion, clinical research, value evaluation, the rest questions, etc. It is believed that deep research work has been done on explanations, emendation and translation regarding A-B Classic of Acupuncture and Moxibustion. However, the exploration work on the theory and application is far from enough. Therefore, beginning from historical and cultural background, we should analyze the humanistic spirit of HUANG Fu-mi combined with A-B Classic of Acupuncture and Moxibustion to perform a deep exploration, so we could have a thorough and comprehensive research on HUANG Fu-mi's academic thoughts.

[Objective]To examine whether collagen scaffold(CS) would strengthen calcium phosphate cement(CPC) in vitro,and to investigate whether CPC enhanced with CS would accelerate the osteogenesis for repairing bone defect in rabbits.[Method] A standard 3-piont flexural test was used to fracture the set specimens and to measure the flexural strength,work-of-fracture(WOF) and elastic modulus of CPC and cpclcs.Both cements were implanted into cylinder cavities drilled in 20 rabbit femoral condyles.After 22 and 54 weeks of implantation,histological observations were performed.[Result]The CS had significant effects on composite of mechanical properties.The CPC/CS had a flexural strength 64.2% higher,WOF 3 933.3% higher,and elastic modulus 45.7% lower than the CPC without CS.At 22 weeks,histological study showed collagen fibers of the CPC/CS composite were entirely resorbed and new bone was formed instead.With unreinforced CPC,there were a little bone formation and biodegradation of cement on the margin but not in the interior of CPC.At 54 weeks,plentiful growing bone and bone marrow-like tissue fully filled in pores created by biodegradation of CPC/CS.Although bone formation and biodegradation of cement were more obvious on the margin of CPC cylinder at 54 weeks than 22 weeks,new bone did not present in the interior of CPC yet.[Conclusion]Collagen scaffold not only reinforces CPC,but also accelerates bone formation in the interior of CPC/CS composite.Therefore,CPC/CS could be novel biomaterial as an endosteal implant.
