Objective To observe the influence of δ-opioid reperfusion in rats with change in serum protein S-100B level and to explore the neuroprotective effect of DADLE during cerebral resuscitation. Method The model of global cerebral ischemia and reperfusion was induced by bilateral common carol id artery occlusion combined with hypotension. Fifty SD rats were randomly divided into five groups: sham operation group, model group, DADLE pretreated group, DADI.E treated postischemia group, DADLE treatment during reperfusion group ( n = 10 for each group) .In sham operation group,the rats were operated without ischemia and treatment; in model group, rats had global cerebral ischemia and reperfusion model up without any treament; in DADLE pretreated group, rats received DADlE before ischemia; in DADLE treatment postischemia group,rats had DADLE immediately after ischemia; in DADLE treatment during reperfusion group,rats got DADLE during early reperfusion. After the establishment of model, serum protein S-JOOB was measured by using ELlSA.One-way analysis of variance and SNK test were used for comparison between groups. Results The serum protein S-100B level was (475.56±1.93) pg/ml in sham operational group and that was much lower than that in model group and DADLE treatment groups. While the levels of serum protein S-100B in all DADLE treatment groups were reduced significantly in comparison with model group. There were no differences in the levels of serum protein KS-100B between DADLE treatment groups. Conclusions The δ-opioid receptor DADLE exerts neuroprotective effects on global cerebral ischemia and reperfusion in rats.

In order to ef fectively control the quality ofSophora lfos carbonisatus (flower and flower buds), this study established quality control methods and standard of the decoction pieces. Referring to the related methods in appendix of Chinese Pharmacopoeia (2010 Edition), the moisture, total ash, acid insoluble ash, alcohol extracts ofSophora lfos carbonisatus were measured, respectively, with rutin, quercetin as control substance. The eluents for rutin and quercetin are ethyl acetate - formic acid - water (8: 1:1) and chloroform - methanol - water (6.5:1:1), respectively and all TLC plates were observed at 365 nm. Total flavonoids are measured by visible - UV - spectrophotometric, and rutin and quercetin were determined by HPLC. The chromatographic conditions for rutin are: Kromasil C18 as the stationary phase, methanol -1% acetic acid (32:68) as mobile phase, flow rate: 0.8 mL·min-1, detection wavelength 257 nm,the column temperature 35℃; for quercetin: Kromasil C18 as the stationary phase, methanol -0.4% acetic acid (44:56) as the mobile phase, flow rate: 0.8 mL·min-1, detection wavelength 257 nm, the column temperature 40℃.The contents of moisture, total ash, acid insoluble ash, should not exceed 6%, 16%, 8.0% in flower and not exceed 6.0%,9.0%, 1.5% in buds, respectively. Under the conditions of TLC, in flower and flower buds, 2 reference substances can be separated well with others. Extract, total flavonoids, rutin, quercetin were no lower than 40.0%, 5.0%, 2.5%,0. 2% in flower and no lower than 45.0%, 10.0%, 5.0%, 0.9% in buds, respectively. The established standards can improve the levels of quality control, provide experimental data for safety and efficacy of clinical application of Sophora flos carbonisatus, and also offer supporting data for the Chinese Pharmacopoeia 2015 Edition.

Objective To study the feasibility and safety of performing nephrectomy together with the removal of complicated inferior vena cava tumor thrombus under profound hypothermia and arrested circulation. Methods After made the median thoraco-abdominal incision, the exploration of the abdominal organs was done. The right kidney, inferior vena cava and renal pedicle were well exposed then. After the whole body heparinization, cannulas were put into ascending aorta, superior vena cava, aortic root and right superior pulmonary vein. The body temperature was reduced to 20℃ with cardiopulmonary bypass unit and the extracorporeal circulation was stopped then. Cut open the inferior vena cava at vena renalis dextra ingress and the F16 urinary catheter was inserted into atrum dextra through inferior vena cava and inflated. The tumor thrombus was pulled out and the right kidney was removed. The inferior vena cava incision was sutured to close and the extracorporeal circulation was resumed and patient was re-warmed.Results The operation time was 330 min and the extracorporeal circulation time was 90 min, while the profound hypothermia with circulatory arrest time was 20 min. The estimated blood loss during operation was 400 ml and 6 unit red cells and 600 ml blood plasm were transfused. The patient was awaked 2.5 h after the operation, food intake resumed 4 days after operation and the patient was discharged on day 10 post-operatively. After 6 months'follow-up, there were no local recurrence and metastasis occurred. Conclusion The technique of profound hypothermia and circulation arrest could improve the safety and efficacy in the treatment of renal cell carcinoma with suprahepatic (level Ⅲ) caval tumor thrombus.
