The effect of dark tea fermentation liquid with Eurotium Cristatum on the activity of digestive enzyme was researched, as fellowing amylase, protease, lipase. The results showed that dark tea fermentation liquid with Eurotium Cristatum may increase remarkably the activity of ?-amylase and protease, but decrease efficiently the activity of lipase. The fermentation liquid improves the digestion and absorption of starch and protein, but inhibits the decomposition and absorption of fat, so it can explain the mechanism of Fu-brick tea's health functions.

Objective To analyze the survival rate of HIV /AIDS patients receiving highly active antiretroviral therapy(HAART)since the implementation of the national Four Free and One Carepolicy against HIV in Hangzhou.Methods Clinical data of 2370 AIDS patients were collected from National AIDS Comprehensive Treatment Information System Treatment Library from 2004 to 2014.The data, including basic information,viral load,CD4 +T lymphocyte counts,starting time of treatment,WHO clinical stage,infection pathways and follow-up were respectively analyzed.Kaplan-Meier and Cox proportional hazards models were used to analyze the survival rate and the factors affecting survival.Results The total follow-up time was 3968.14 person years and 57 patients died in 2370 patients with a mortality rate of 1 .44 /100 person years (57 /3968.14).Kaplan-Meier method showed that the cumulative survival rates of the first,third and fifth year were 98.08%,96.20% and 95.24%,respectively.The overall mortality rate fell from 6.06 /100 person years in 2006 to 1 .44 /100 person years in 2014.The mortality rate of AIDS-related disease declined from 1 .10 /100 person years in 2009 to 0.90 /100 person years in 2014.Multivariate Cox regression analysis showed that the risk of death for patients with CD4 +T 200-349 cells/μL was 0.466 times(95%CI 0.246-0.882)as that for patients with CD4 +T cells <200 /μL.The risk of death was 3.408 times(95%CI 1 .365-8.506)in patients aged≥ 50 years,3.788 times(95%CI 1 .645-8.718)in patients aged 40 to <50 years,and 2.593 times(95%CI 1 .139-5.905)in patients aged 30 to 40 years as that in patients aged <30 years.The mortality risk for patients with baseline WHO stage Ⅲ and Ⅳ was 1 .960 times as patients with WHO stage Ⅰ and Ⅱ (95% CI 1 .117-3.439 ).Conclusions Patients with increased age,low CD4 +T counts and baseline WHO stage Ⅲ or Ⅳ are main risk factors affecting survival rate of HIV /AIDS patients,early antiviral therapy is the key for improving the survival rate of patients.

To investigate the effects of complex danshen solution and heparin on the changes of blood coagulation factors in rats with hemorrhagic shock, and to explore the therapy of coagulopathy by compound danshen solution, the rat model of hemorrhagic shock was set up, 40 SD rats were randomized into four groups: sham operation, shock, compound danshen solution and heparin groups, each group was composed of 10 SD rats. Plasma SFMC, TM, ATIII, D-D, t-PA, PAI levels and APTT were detected, incidences of bleeding complications between heparin and danshen group were compared. The results showed that plasma SFMC, D-D levels in shock group were higher but ATIII level in shock group was lower than that in sham operation group, compound danshen solution group and heparin group (P < 0.001), TM levels obviously increased in shock group and heparin group (P < 0.001). There was no significant difference between compound danshen solution and sham-operation groups. Plasma t-PA, D-D levels obviously increased after shock for 2 hours, PAI level reached the peak after shock for 4 hours, but t-PA decreased. After shock for 6 hours, plasma PAI descended, t-PA continually drop in, but PAI and D-D remained in higher levels. Plasma D-D level in heparin group was lower than that in shock group, t-PA level was higher than that in shock group, but there was no significant difference between in heparin and shock groups. Plasma t-PA, PAI and D-D levels in compound danshen solution group were lower than that in shock group. APTT of danshen group was lower than that of shock group and heparin group. Bleeding incidences was 30% in heparin group and 0% in danshen group, respectively. It is concluded that compound danshen solution may used to treat hypercoagulation and hyperfibrinolysis. In comparsion with heparin, danshen posses-ses advantages of safety with less bleeding complication and needs not tight monitor.

The stability of melittin in different solvents (water, deoxygenated water, physiological saline, PBS, 50% ethanol, ethanol, glycerol)was studied and the results showed that the stability of melittin is not influenced by light, temperature and pH in 50% ethanol, which melittin can be completed dissolved when compared with ethanol and glycerol, in such, 50% ethanol was chosen as solvent storage when measured content of melittin. Then the effect of different concentrations of PBS, the pH of PBS and rat skin ho- mogenates were tested, and the results showed that melittin was degraded rapidly at low concentration solution and low ionic strength. Increasing pH of PBS and rat skin homogenate can accelerate the degradation of melittin. These researches provide an experimental ba- sis for further study of melittin.
