Objective To assess the value of transcatheter superselective arterial embolization in treatment of renal traumatic hemorrhage. Methods 20 patients underwent digital subtraction angiography with definite diagnosis before embolization. Embolization materials used in the study were gelfoam sponge chips and steel coils including 14 cases of segmental arteries with their branches through superselective renal arterial embolization. 6 cases were treated by selective renal arterial embolization. Results After renal artery embolization, macroscopic hematurin disappeared on 3th to 5th day after the procedure. With an average of 29 months of follow-up, there was no recurrent hemorrhage associated with normal renal function and blood pressure. Conclusions Superselective renal arterial embolization has advantages of less aggression, less complications, and good hemostatic efficacy, with maximal preservation of renal tissue and function for treatment of mild and moderate renal injuries.

TCM higher education has cultivated a large number of high-level TCM professionals in the past sixty years.Against the backdrop of social progress in China,a system of cultivating faculty of TCM higher education has been put in place that features an organic link-up between college,after graduation and continuing education.Academic community serves as a starting point in the system.This paper mainly illustrates our understanding of academic community,life-long education through connecting the three phases and its implementation.

Objective To evaluate the effect of therapeutic hypercapnia on the balance between cer-ebral O2supply and demand in the patients undergoing arthroscopic shoulder surgery in the beach chair posi-tion(BCP). Methods Forty-eight patients of both sexes, aged 21-64 yr, weighing 45-80 kg, of Ameri-can Society of Anesthesiologists physical statusⅠorⅡ, scheduled for elective arthroscopic shoulder surgery in the beach chair position, were divided into 2 groups(n=24 each)using a random number table: control group(group C, end-tidal pressure of carbon dioxide 35-40 mmHg)and therapeutic hypercapnia group (group H, end-tidal pressure of carbon dioxide 45-50 mmHg). The regional cerebral oxygen saturation (rSO2)was recorded after induction and before BCP, immediately after BCP, at 3, 6, 9, 12, 15, 18, 21, 24, 27 and 30 min after BCP and at the end of surgery(T0-12). The occurrence of cerebral desaturation events, extubation time, duration of stay in postanesthesia care unit, development of nausea and vomiting and requirement for vasoactive drugs were recorded during surgery. Results Compared with the baseline at T0, the rSO2was significantly decreased at T1-12in group C and at T2-6in group H(P<005). The rSO2was significantly higher at T1-12, and the incidence of cerebral desaturation events was lower in group H than in group C(P<005). There was no significant difference between the two groups in the extubation time, dura-tion of stay in postanesthesia care unit, incidence of nausea and vomiting or requirement for vasoactive drugs (P>005). Conclusion Therapeutic hypercapnia can improve the balance between cerebral O2supply and demand in the patients undergoing arthroscopic shoulder surgery in the BCP.
