Objective To compare with the different effect of the plasma and serum containing Danshen Injection (DI) on the angiogenesis. Methods The DI-containing plasma and serum at different concentrations and sampled at different time were prepared. The effect of DI-containing plasma and serum on the angiogenesis of chicken chorioallantoic membrane (CAM) was observed by using CAM model. Results The proliferation of vessels in all DI-containing plasms and serum groups and DI group was obvious as compared with that in the group of the blank plasma and serum(P

Objective: To investigate the effect with its possible mechanisms of zacopride on vasodilatation of isolated coronary arterial rings in experimental rats.
Methods: The tension of vasodilatation of isolated coronary arterial rings of male SD rats was recorded by Powerlab and DMT system. The rats were divided into 4 groups: +Endo (vehicle) group, +Endo (zacopride) group and -Endo (vehicle) group, –Endo (zacopride) group.n=6 in each group. The vasodilatation effects of zacopride on KCl (60 mmol/L) and U46619 (10-6 mol/L) pre-constricted arterial ring were recorded; the effects of different agents on zacopride caused vasodilatation were studied.
Results: In both +Endo (zacopride) and –Endo (zacopride) groups, zacopride showed a dose dependent vasodilatation effect on coronary ring pre-constricted by KCl and U46619. The maximum vasodilatation effect of zacopride in KCl treated+Endo (zacopride) group was (90.15 ± 6.38) %, in U46619 treated-Endo (zacopride) group was (81.67 ± 4.97 ) %; the maximum vasodilatation effect of zacopride in KCl treated-Endo (zacopride) group was (85.48±5.04) %, in U46619 treated–Endo (zacopride) group was (79.65 ± 3.51) %, compared to each corresponding vehicle group, allP<0.05. The inhibitor of IK1 channel, BaCl2 could signiifcantly reduce the vasodilatation effect of zacopride in KCl and U46619 pre-constricted coronary ring,P<0.05. However, the inhibitor of eNOS (L-NAME), the blocker of KCa channel (TEA), blocker of Kv channel (4-AP) and blocker of KATP channel (Glib) had no such signiifcant effects, allP>0.05.
Conclusion: Zacopride had vasodilatation effect on coronary arterial ring which was pre-constricted by KCl and U46619, which might be related to the channel of IK1.

OBJECTIVETo explore the optimal treatment for craniocerebral trauma complicated with thoraco-abdominal injuries.

METHODSA total of 2165 cases of craniocerebral trauma complicated with thoraco-abdominal injuries admitted to our hospital between July 1993 and June 2003 were retrospectively studied. Among them, 382 cases sustained severe craniocerebral trauma (in which 167 were complicated with shock), 733 thoracic injuries, 645 abdominal injuries and 787 thoraco-abdominal injuries. On admittance, 294 cases had developed shock. With the prime goal of saving life, respiratory and circulatory systems and encephalothilipsis were especially treated and monitored. Priority in management was directed to severe or open injures rather than to moderate or closed injures. For cases with cerebral hernia due to intracranial hematoma and severe shock due to blood loss, cerebral hernia and shock were treated concurrently.

RESULTSAfter treatment, 2024 (93.49%) cases survived and the other 141 (6.51%) died. Among patients who had severe craniocerebral injury with shock and those without, 78 (46.71%) and 53 (24.56%) died, respectively. For patients who had underwent craniocerebral and thoraco-abdominal operations concurrently and those who had not, the death rates were 58.49%-65.96% and 28.57% respectively, indicating a significant difference (P<0.05).

CONCLUSIONSTreatment for hematoma hernia, shock and disturbed respiration is the key in the management of multiple trauma of craniocerebral, thoracic or abdominal injuries, especially when two or three conditions occurred simultaneously. Unless it is necessary, operations at two different parts at the same time is not recommended. It is preferred to start two concurrent operations at different time.
