Objective To analyze hematosis of modified homemade Buxue decoction discriminate on patients with hemorrhagic anaemia after unilateral total hip arthroplasty and prognosis.Methods88 patients with hemorrhagic anaemia who underwent unilateral total hip arthroplasty in our hospital from February 2015 to Janurary 2017 were selected, they were randomly divided into the observation group and the control group, 44 cases in each group.The control group received pure western medicine after unilateral total hip arthroplasty, the observation group added modified homemade Buxue decoction discriminate on the basis of the control group.Clinical therapeutic effect on anemia, hematosis indexes including hemoglobin (HB), red blood cell (RBC), erythrocrit (HCT) in the two groups were compared, occurrence of complications during postoperative treatment, hip scores were used to compared prognostic differences in the two groups.ResultsTotal effective rate of the observation group 95.45% was significantly higher than the control group (81.82%) (P<0.05);there was no significant difference in Hb, RBC and HCT level before the treatment in the two groups, Hb (130.23±13.09)g/L, RBC (4.16±0.71)×1012/L and HCT (0.42±0.03) in the observation group after the treatment were significantly higher than the control group (P<0.05);complication rate in the observation group 9.10% was significantly lower than the control group (25.00%) (P<0.05);there was no significant difference in hip joint function scores before the treatment in the two groups, hip joint function score in the observation group after the treatment (79.73±5.42)scores was significantly higher than the control group (P<0.01).ConclusionTreatment effect of modified homemade Buxue decoction discriminate on hemorrhagic anaemia after unilateral total hip arthroplasty is significant, can promote recovery of hematosis, hip joint and motor function effectively.

13th Five-Year period is China's comprehensive completion of the decisive stage of a well-off society,when the development of public hospitals is facing great opportunities and challenges.Five development concepts introduced by the fifth Plenary Session of the 18th CPC Central Committee,offer guidance on public hospital reform and development.Among such concepts,innovation is leading the first power of hospital development;Coordination is the inherent requirements of the hospital' s sustainable and healthy development;Green is a necessary condition for the sustainable development of the hospital,and also an important reflection of the hospital development achievement;Opening is the only way for the rapid development of hospital;Sharing is the essential requirement of hospital development.Five development concepts shall guide the reform and development of Chinese public hospitals during the period of 13th Five-Year.

Objective By discussing the relationship between allergic diseases caused by pollen,pollen density and meteorological factors,making out the warning for the allergic diseases caused by pollen,in order to provide a public service.Methods The data of meteorology from 2001 to 2005 of Tianjin,the pollen monitoring of the Weather Iron Tower Station day by day and the allergic patients whose skin tests were positive in Tianjin Municipal Chest Hospital and Tianjin Municipal Police Hospital were taken to statistical analysis on the rule of seasonal allergic diseases,the relationship between allergic diseases and pollen density and meteorological factors(such as vapor pressure and wind speed),and the prediction equations were obtained for allergic diseases caused by pollen.Results There was obviously positive correlation between the incidence rate of pollinosis(y),weighted pollen density(x11) and vapor pressure(x22) within twenty-days before the onset.The multiple correlation coefficient was 0.805 and the prediction equation was y =2.385+ 0.079 3x11 +3.507x22.Conclusion There is a close correlation between the incidence rate of pollinosis and pollen density.The allergic diseases caused by pollen are also affected by the change of air temperature,varieties of pollen and humidity.

brain and fatty. The accumulation excretion ratios within 96 h were 70.16% in urine and only 1.35% in feces after iv administration in rats, while within 24 h was 3.46% in bile. Conclusion The results of pharmacokinetics of novel r-hirudin in rats given by iv determined by RA are different from those determined by TCA-RA, but the trends indicated by the two methods are the same; urine excretion is the major excretion pathway.

AIM: In order to investigate the possible cumulative and chronic toxicity of paralytic shellfish poisoning (PSP) and provide more information on toxicity of PSP. METHODS: The sub-acute toxicity of PSP was evaluated in the rat. PSP was extracted from the seafood in market, and the toxicity of the extract was determined by mouse bioassay. The extracts in different toxicity were administrated to rats through gastrotube for 35 days. The biochemical and pathological changes in vital tissues in rats were examined by the detections of some function indexes in blood and urine and the observations under optical microscope during both the exposure period and the subsequent 10-day withdrawal term. RESULTS: No biochemical and pathological changes in tissues occurred for the control and low-dose group (4.6 ?g STX/kg), whereas some changes happened for the middle (9.2 ?g STX/kg) and high groups (18.4 ?g STX/kg). In experiment, some renal function indexes changed in the mid-dose group, and some of the cardiac, hepatic and renal functions indexes altered for the high dose group with some changes in weight of the thymus gland and spleen. What is more, the liver and kidney became indistinct with some inflammatory changes, and some muscles had ruptured for the 40% rats in high-dose group. CONCLUSION: These results suggest that long-term intake of PSP at a concentration, which doesn't exceed the threshold of standard, has some toxicity on rats, and that the toxicity of PSP has an accumulative effect. In a word, it is unsafe for us to eat frequently bivalve seafood polluted by PSP toxins.

Aim To study the inhibitory effects of gambogenic acid in combination with miR-218 on cervical cancer HeLa cells and its mechanisms.Methods Eukaryotic expression vector of miR-218(pmi8-218) was transfected into HeLa cells.Transcript levels of miR-218 were quantified by real-time quantitative PCR.HeLa cells were incubated with different concentrations of gambogenic acid alone or in combination with pmiR-218.The cell growth inhibiting ratio of HeLa cells was assessed by MTT assay.Cell apoptosis was measured by fluorescence activated cell sorting.The expression levels of Bcl-2, Bax and E-cadherin were measured by Western blot and qRT-PCR.Results Levels of miR-218 transcript significantly increased in pmiR-218 transfected HeLa cells.Overexpression of miR-218 may enhance the sensitivity of HeLa cells to gambogenic acid.Over expression of miR-218 could enhance the effect of gambogenic acid on inhibition cell proliferation, promoting apoptosis of HeLa cells.pmiR-218 could enhance the regulation of Bax expression and decrease the expression of Bcl-2 in HeLa cells.Conclusions Over expression of miR-218 may enhance the sensitivity of HeLa cells to gambogenic acid;miR-218 can enhance the effect of gambogenic acid on inhibition cell proliferation and promote the apoptosis of HeLa cells, and the mechanism may be related to down-regulation of Bcl-2/Bax expression.
