OBJECTIVE:To evaluate the status quo and the tendency of the use of antihypertensives in our hospital. METHODS: The utilization of antihypertensives during 2005～2007 in our hospital were analyzed statistically in respect of the consumption sum, DDDs and average daily cost etc. RESULTS: Over the 3 years, the consumption sum and DDDs of the antihypertensives used in our hospital increased markedly, especially those of calcium antagonists, angiotensin, ACEI and diuretic antihypertensives. The consumption of AGT Ⅱreceptor blocking agents increased year by year. CONCLUSION: The utilization structure of antihypertensives in our hospital is basically reasonable. It is of great importance to develop effective compound antihypertensive drugs with low-cost and less ADRs.

Objective To systematic review the methodological quality of guidelines for Guillain-Barré syndrome (GBS) in children, to provide a reference for clinical evidence-based medicine. Methods Guidelines concerning GBS were electronically retrieved from PubMed, EMbase, CBM, Wanfang data, CNKI and Vip. The guide databases includes major medical institutions and industry sites such as NGC, GIN, TRIP , CDC, IDSA, AAP, WHO, Chinese Health and Family Planning Committee website, library of clinical guidelines China and Chinese clinical guidelines for collaboration. All the data were searched from inception of the database or network to Oct. 2013. Two reviews independently screened literature according to the inclusion and exclusion criteria, and assessed the quality of guideline using the AGREEⅡ. Intraclass correlation coefficient (ICC) was used to examine the conformance of the raters' evaluation scores. Results A total of 5 guidelines concerning GBS were included, with a time range from 2003 to 2012, and origins from USA, EU and Canada. The final recommendation levels of the 5 articles were level B. According to the AGREEⅡ, domain 3 and 4 showed the higher scores, and scores were generally low in domain 5. Plasma exchange (PE) and intravenous immuneglobulin (IVIG) showed positive effects on the treatment of GBS. But it was not recommended that combined PE and IVIG. Corticosteroids are also not recommended for GBS treatment. Conclusions The recommendations of medicines for GBS are basically consistent. However, the classification criteria of the levels of evidence and recommendation are still unconsistent and suboptimal. The guidelines on GBS should be improved in“Applicability”in future.

Objective:To investigate the levels of AP-1 in hippocampus of rats at different time points after carbon monoxide poisoning.Methods: Carbon monoxide poisoning delayed encephalopathy model by using intraperitoneal injection of carbon monoxide.Uesd HE observed the pathological changes in hippocampus of rats.The levels of AP-1 was observed by immunohistochemistry and Western blot analysis.TUNEL was used to detect apoptotic neurons in hippocampal CA1 area.Results: HE dyeing conditions,the hippocampus cell of air group (AC) and blank group (BC) were normal at each time point.Pathological changes occurred in the hippocampus cell of Carbon monoxide group (CO),reduction in the number of cells,disorder of cells,intercellular space expansion,nuclear fragmentation,anachromasis and pyknotic.Immunohistochemical results,the AP-1 expression level at each time point in group CO were higher than group AC and BC.On 3th day it reached a peak.The comparison at all time points among the groups in the first three days were significantly different in statistics(P<0.05).Western blot results,the expression of AP-1 was consistented with the immunohistochemical results on the time distribution trend.TUNEL results,AI in group CO was higher than those in group AC and BC at all time points,there were significant differences(P<0.05) and 7th reached the peak of apopotsis.Conclusion: Inside the hippocampus of rats,there are increasing in AP-1 . Maybe it is one of the important pathogenesis of DEACMP .

Objective To study the effects of nuclear factor E2-related factor 2 (Nrf2) in delayed encephalopathy in rats after acute carbon monoxide poisoning. Methods One hundred and sixty-eight rats were randomly divided into three groups: forty-eight rats in the blank control group (BC group), sixty rats in the air control group (AC group) as well as in the carbon monoxide poisoning group (CO group). The DEACMP model was established by improved intraperitoneal injections. The animals were valuated at 1st ,3rd, 7th, 14th, 21th, 28th day after acute carbon monoxide poisoning. Tunnel method was used to test the pyramidal cell apoptosis in the hippocampal CA1 area. The expression of Nrf2 was tested by immunohistochemical method and Western Blot method. Result In the CO group, the apoptosis index (AI) started to increase from first day and achieved it's peak at the 7th day (20.20 ± 1.78), then began to decrease slowly. The apoptosis index was still higher than that in the other groups at 28th day. And the apoptosis index of the CO group was markedly higher than the other two groups at each time point. The Nrf2 protein started to increase from 1st day in the CO group , reached its peak at 3rd day (8.20 ± 1.08), reduced later, maintained at a high level at 28th day, and expressed significantly higher than other groups at each time point. Conclusions The Nrf2 has a linear correlation with apoptosis , and plays a dual role in DEACMP because it rapidly increased in first three days to against apoptosis. But it continuously has been excessive expressed from 7th to 28th day in promoting the apoptosis of hippocampus pyramidal cells and may be a positive factor in DEACMP.

Objective To investigate the influence of calcitonin on bone mineral density and biomechanics around the artificial pros-thesis in ovariectomized diabetic rabbit model. Methods Fourteen femina New Zealand white rabbits at the age of 5 months old were select-ed, which weight 2.24 -2.65kg, averaging 2.26kg. First, the model of rabbit with diabetic osteoporosis was successfully established by the compound method of ovariectomy plus streptozotocin. Osteotomy in the middle part of femur was performed in both groups, fixation of artifi-cial prosthesis was done with 3.0 kirschner wire. After that, Rabbit models with diabetic osteoporosis were randomly divided into experimen-tal group and control group. Rabbits in the experimental group were treated with calcitonin 6U intramuscular injection once every other day. In control group, intramuscular injection of normal saline solution 1.5ml once every three days. Rabbit models of two groups were sacrificed in the 24th week. The BMD of the region of interest (ROI) around the prosthesis were detected before experiment and 8, 16 and 24 weeks after injection. After rabbits were killed, experimental femurs in both groups were complete removal and soft tissues were rejected. Determi-nation of the pull-out and torsion bone biomechanics experiments of prosthesis was done in both groups respectively. Results The BMD of ROI in the experimental group before operation was (0.1863±0.004)g/cm2 and (0.1753±0.005)g/cm2 in 24 weeks after operation, in control group before operation was (0.1865±0.002)g/cm2 and (0.1638±0.005)g/cm2 in 24 weeks after operation. There were significant difference between the two groups(P < 0.05). Biomechanical show that the pull-out strength in the experimental group was (312.68±8.73 )N/cm2 and (205.43±12.45 ) N/cm2 in control group. There were significant difference between the two groups(P < 0.05). The tor-sion strength in experimental group was (80.47±2.51) N/cm2 and (38.52±0.64) N/cm2 in control group. There were significant differ-ence between the two groups(P < 0.05). Conclusion Salmon calcitonin can reduce the bone turnover rate around prosthesis and decrease bone absorption in the rabbit of diabetic osteoporosis models, accelerate the bone formation around prosthesis, and increase the BMD. It can ameliorate the quality of bone around prosthesis, improve its biomechanics property, and increase the holding power between prosthesis and body mass. It is of clinical significance for the prevention and treatment of aseptic loosening artificial prosthesis.

Objective To observe the protective effects of natural antioxidant tea polyphenols(TP) on myocardial free radical metabolic disorder in mice induced by inhalation of hypobaric pure oxygen under 5500 m hypobaric condition. Method Fourty-two male Kunming mice were randomly divided into three groups(n=14 each):group A, normal control; group B, inhalation of pure oxygen(>96%) at simulated altitude of 5500 m in an animal altitude chamber;group C(TP protection group), same as group B but 100 mg/kg of TP was given orally before the exposure. The exposure time was 2 h/d,3 d/wk for a total of 8 wk, and distilled water was given to groups A and B before exposure. After experiment, the mice were decapitated on the next day and the heart was quickly removed. Malondialdehyde(MDA) concentration, superoxide dismutase(SOD) activity and nitric oxide(NO) content were measured. In addition, Cu,Zn-SOD and inducible NO synthase(iNOS) enzymatic contents in myocardial tissue were qualitatively examined by immunohistochemical assaying. Result Compared with the control, MDA concentration, SOD activity and Cu,Zn-SOD enzymatic content in group B were significantly increased(P<0.05).But in TP protection group, myocardial MDA formation was significantly decreased(P<0.01) and SOD activity and Cu,Zn-SOD expression restored to normal. On the contrary, myocardial NO generation and iNOS expression were significantly reduced after repeated inhalation of hypobaric oxygen at 5500 m.NO metabolism regained to normal after repeated administration of TP. Conclusion Natural antioxidant TP had protective effects on myocardial free radical metabolic disorder induced by inhalation of hypobaric pure oxygen under 5500 m hypobaric condition.
