ABSTRACT
Objective To investigate the significance of hypoxia inducible factor lα and lactate and lactate clearance in patients with septic shock.Methods A prospective observational study was conducted.Thirty healthy volunteers (control group) and 40 cases of septic shock patients in EICU were recruited.According to the survival time,40 patients with septic shock were divided into survival group (21 cases,survival time ＞ 28 days) and death group (19 cases,survival time ≤ 28 d).The HIF-lα level was tested by ELISA assay.Lactate level of 0,6,12,24 h in arterial blood were also tested.Lactate clearance rate of the 6 h,12 h and 24 h were calculated.The association of HIF-1α and lactate level and lactate clearance rate,APACHE Ⅱ score and prognosis were evaluated.Results 40 patients with septic shock,20 male and 20 femnales,the mean age was (61.3 ± 12.8) years.The 28 day mortality rate was 47.5％.The average APACHE Ⅱ score was (23.7 ± 4.83) and arterial blood lactate levels was (5.88 ± 2.73) mmol/L.In death group and survival group,the levels of HIF-1α levels and blood lactate were significantly higher than that in the control group (P ＜ 0.05).The death group increased more significantly (P ＜ 0.05).In death group,the 6 h,12 h and 24 h lactate clearance rate were lower than the survival group (all P ＜ 0.01).APACHE Ⅱ score were higher than that in survival group (P ＜ 0.05) and the difference is statistically significant.The lactate and HIF-1α were positively correlated (r =0.868,P ＜ 0.01).Blood lactate and HIF-1α levels were all positively correlated with APACHEⅡ score (r =0.804,P ＜ 0.01) and (r =0.811,P ＜ 0.01).Conclusion The level of HIF-1α,blood lactate,lactate clearance rate are closely related with the severity and prognosis of septic shock and may become an important indicator of the prognosis.
ABSTRACT
Objective To investigate the effects of Yiqi Congming pill combined with western medicine on hearing and sleep quality in tinnitus patients. Methods 60 tinnitus patients caused by liver fire treated in our hospital from May 2015 to February 2017 were selected for the study and randomly divided into the observation group and the control group, with 30 cases in each group. The two groups were given conventional western medicine and Yiqi Congming pills combined with western medicine respectively. The effective rates of treatment, the speech pure-tone average (PTA), speech recognition threshold (SRT) and Pittsburgh Sleep Quality Index (PSQI) were compared between the two groups, and the adverse reactions were observed. Results The effective rate of the observation group was 93.33％, which was higher than that of the control group with 73.33％ (P<0.05). After treatment, the levels of PTA, SRT the scores of PSQI were significantly lower in the observation group than those in the control group (P<0.05). There were no differences in the incidence rates of adverse reactions between the two groups. Conclusions Yiqi Congming pill combined with western medicine can effectively treat tinnitus caused by liver fire, and improve hearing and sleep quality without obvious adverse reactions. Therefore it is worthy of clinical promotion and application.
ABSTRACT
Objective To confirm the synthesis conditions of Ganoderma lucidum Polysaccharide-Fe (Ⅲ) Complex, and study on adsorption kinetics of it.Methods Adopt alcohol sedimenting technique and decoloring, dialysis, etc, extracting refined polysaccharide from Ganoderma lucidum.The solution of the Polysaccharide with FeCl3 react in alkaline conditions.To synthesize the polysaccharide iron complexes(GPC).The iron contents were determined by o-phenanthroline spectrophotography and and study on adsorption kinetics of Ganoderma lucidum Polysaccharide-Fe (Ⅲ) Complex.Results GPC is red brown and shapeless powder,it's liable to dissove in water,its solution is neutral,without precipitation,dissociation and Fe3 +at the pH from 3 to 12,and insoluble in organic solvents.So GPC is very stable.At the same time under different temperatures, the Fe3 + and polysaccharide on the adsorption quantity of increased gradually over time, the basic stability after 1.5 h.At the same time, with different temperatures the adsorption quantity of polysaccharide Fe3 + increases with the rise of temperature.Conclusion GPC may become a new ideal oral iron.Time and temperature are the key fabrication processes of GPC.
ABSTRACT
Objective To observe the effect of Jisheng injection(JI)in preserving isolated heart of mice.Methods Langendorff' s isolated -perfused mouse heart mod el was established.The isolated hearts were preserved in modified Eu-ro -Collins solution(MECS)and MECS with JI added for 3h,7.5h and8.5h respectively.Cardiac functio n,coronary flow and myocardial water -volume (MWV)were observed after 3h ,7.5h and 8.5h of preservation,heart reactivatio n(HR)rate,coronary flow,MWV and time for HR were also observed.Results After 3h of preservation and 20min,30min or 40min of reperfusion,cardiac function and coronary flow in three M ECS +JI groups and especially in that of large dose were improved as compared with t hose in MECS group;MWV in large -dose and moderate -dose groups was obvi-ously lower than that in MECS group(P
