BACKGROUND: Prevention of tissue damage during early hours of cerebral ischemia has remained a major challenge in acute stroke management.Whether the application of hyperbaric oxygen (HBO) can protect cerebraltissue or not remains a question to be answered.OBJECTIVE: In cerebral ischemia-reperfusion rat model we studied the change on CGRP and β-endorphine levels and the therapeutic implication with hyperbaric oxygenation.DESIGN: A randomized controlled animal study.SETTING: Animal Research Department of Capital University of Medical Science.MATERIALS: The experiment was carried out at the Animal Research Department of the Capital University of Medical Science from December 2003 to February 2005. Sixty three healthy Sprague-Dewey female rats were randomly divided into 9 groups. There were 7 in the sham operation group. Four groups with 7 in each group received cerebral ischemia followed by reperfusion (IR) and blood sample taken at 6, 24, 48 and 96 hourrespectively. Another 4 groups (IR-HBO) with 7 in each received cerebral ischemia and reperfusion under hyperbaric oxgenation with blood sampling at 6, 24, 48 and 96 hours.INTERVENTIONS: With the exception of sham operation groups, animals in all the experimental groups were exposed to global cerebral is chemia of 20 minutes duration. Sham operation group and the IR groups remained under the normal atmospheric pressure. The HBO chamber was flushed with 100% oxygen for 5 minutes and raised the pressure in 5 minutes to a steady pressure at 0.2MPa. Rats in IR-HBO groups were put into the chamber with inhalation of 100% oxygen for 45 minutes and decompression was done for 15 minutes. The rats in HBO group were placed into the HBO chamber after 3-hour post reperfusion on the first day and this treatment was repeated for three consecutive days, always at the same time.Plasma was collected after 6 hours, 24 hours, 48 hours or 96 hours post cerebral reperfusion, respectively.MAIN OUTCOME MEASURES: The level of CGRP and β-EP in the plasma were measured by RIA (Radio-immunoassay).RESULTS: Sixty-three rats entered the final analysis. ① At 6-hour ischemia-repefusion: CGRP in HBO group was increased (64.12±18.16) ng/L and the onset time was earlier than that in IR group and the level was higher than those in IR group (32.62 ±11.72)ng/L and sham operation group (49.09±8.59)ng/L at the same time point (F=6.614, P ＜ 0.001, P ＜ 0.05). Β-EP level in 6-hour HBO group was slightly increased, but recovered at 24-hour, 48-hour, 96-hour HBO groups. ② At 24-hour and 48-hour ischemia-reperfusion: The plasma CGRP levels of the HBO group recover within 24-hours [(43.53±22.73)ng/L, F=0.390; (46.02±10.64)ng/L,F=0.969, P ＞ 0.05]. ③ 96-hour ischemia-reperfusion: CGRP increase in the IR group (81.74±20.64)ng/L was higher than that in the sham operation group (49.09±8.59)ng/L and the HBO group (40.98±20.52)ng/L at the same time point (F=6.419, P ＜ 0.01); and also obviously higher than those in 6-hour, 24-hour and 48-hour IR group (F=10.806, P ＜ 0.01).The β-EP level at 96-hour HBO group was decreased to the lowest as compared with that in the sham operation group [(370.00±130.15)ng/L,(872.30±403.92)ng/L, F=3.691, P ＜ 0.05].CONCLUSION: ① HBO in the early period of cerebral ischemia can reduce the onset of injury of cerebral tissue through increasing CGRP level and decreasing β-EP level; ②The more times treated by HBO, the better is its therapeutic effect.

OBJECTIVE: Uur aim was to investigate the association between OSAHS and mean platelet volume (MPV) value. METHOD: This study included 70 cases with OSAHS in our ward between Jan. 2012 and Jan. 2014, and the OSAHS patients were divided two groups: mild- to moderate group and severe group; 30 age-and sex-matched healthy subjects was in control group. The correlation among the levels of the number of platelets (PLT), MPV, platelet distribution width (PDW) were evaluated in the two groups. RESULT: PLT count was significantly lower in the severe group than the control group [(202. 8 ± 68. 9] × 10(9)/L, (235. 9 ± 65. 2) × 10(9)/L]; MPV and PDW were significantly higher in the severe group [(10. 9 ± 0. 9), (10. 4±0. 8) fL; (12. 9 ± 1. 9) %, (12. 0 ± 1. 4) %]. There was not significantly difference of MPV between the mild to moderate group and the control group [(10. 7 ± 0. 7), (10. 4 ± 0. 8)fL]. CONCLUSION MPV levels are elevated in patients with the severe OSAHS.

Objective To investigate the impact of human adipose-derived stem cells(hASCs) -plastelet-rich plasma(PRP) composite on the wound healing of radiation skin injury of nude mice.Methods ASCs were isolated from healthy adults after liposuction, conducted primary culture and subculture.PRP was prepared by two-step ultracentrifugation.The ASCs-PRP composite was prepared with ASCs (1 ×107cells/ml) at passage 6 and PRP.Twenty-four nude mice were randomly divided into 4 groups (n=6).A round shaped full-thickness skin defect (D=1cm) was made on the mice back after 20Gy (60Co) round shaped exposure (D=2cm).Right after radiation, wounds were treated as follows,in group A,there was ASCs+PRP, in group B, PRP,in group C, ASCs,in group D, sham group.The wounds were observed at postoperative 7 and 14 days.HE and CD31 stain were observed at 14th days after surgery.Results The wound healing of group A healed completely at 14th days.In group D,the wound healing were slowest and still filled with granulation tissue at 14th days.The wound healing of group B and group C were faster than that of group D, but they haven′t healed completely at 14th days.The inflammatory cells were significantly lower and the blood vessel density positive rate were significantly higher in ACSs+PRP group than in ACSs group,PRP group and sham group (P<0.05).Conclusion ASCs-PRP Composite can accelerate the wound healing of radiation skin injury by promoting wound angiogenesis.

Objective To evaluate the effect of Danshen Chuanxiongqin injection combined with Xuesaitong capsule on blood viscosity in patients with pulmonary heart disease.Methods 80 patients with pulmonary heart disease who were admitted to our hospital between January 2013 and November 2015 were studied,the patients were randomly divided into the combined group and the control group according to the order of admission,40 cases in each group.Control groups were treated with Xuesaitong capsule,and the combined group were treated with Danshen Chuanxiongqin injection on the basis of the control group.The clinical efficacy,blood viscosity(whole blood viscosity,plasma viscosity,whole blood viscosity ratio),blood indexes(blood platelet aggregation rate,erythrocyte aggregation index,erythrocyte deformation index),cardiac function and safety were observed.Results There were no significant differences in blood rheological indexes,LVEF,MAP and HR between the two groups before treatment.After treatment,the whole blood viscosity,plasma viscosity,whole blood viscosity ratio,platelet aggregation rate,erythrocyte aggregation index,erythrocyte deformation index,MAP and HR in the two groups were significantly lower than those before treatment,while LVEF was significantly higher,and the changes in the combined group were more significant than those in the control group(P<0.05).After treatment,the clinical total effective rate of treatment in the combined group(88.89％)was significantly higher than that in the control group(62.50％).Conclusion Danshen Chuanxiongqin injection combined with Xuesaitong capsule is effective in the treatment of pulmonary heart disease.It can significantly reduce blood viscosity,blood related indexes and improve cardiac function.
