Objective To investigate the feasibility and clinical efficacy of the interventional thrombolytic therapy in acute segmental renal infarction.Methods From December 2007 to November 2015 data of patients with acute segmental renal infarction treated in our institute were retrospectively reviewed. There were 5 male patients and 2 female patients, All patients age ranged from 45 to 76 years old ( median 70 years old), All patients had clinical symptoms,including left flank pain with vomiting in 3 patients and right flank pain with vomiting in 4 cases. 4 cases with cerebral thrombosis, atrial fibrillation and hypertension, 3 cases had hypertension and diabetes.4 cases was possible of renal artery embolism diagnosed by Doppler ultrasound, renal arteries showed no abnormality, while other 3 cases had no obvious symptoms.CT test revealed low density area wedge-shaped, coated substrate edge, but no obvious occupying lesions in the pole of the kidneys.Furthermore, enhanced scan showed uneven enhancement, delayed distortion, and the lesion density below the renal parenchyma in the pole of the kidneys.Digital subtraction angiography ( DSA) were performed and the patients were given saline 20 ml and urokinase200 000 U at 15 minutes interval through indwelling catheter injection two times, followed by normal saline 20 ml and urokinase100 000 U injection once.Subsequently, the patients were given urokinase 100 000 U through the indwelling catheters infusion every four hours.Concurrently, the patients were given 6 000 U of low molecular weight heparin sodium injection subcutaneously every 12 h, as well as expansion treatment. 24 hours after the treatment, observing the infarction area by the original DSA catheter angiography.Results All patients were successfully treated.Followed up for 3 months to 7 years, 1 patient died of cerebral infarction and hypertension after 8 months, other patients were alive without evidence of renal infarction recurrence in CT examination, and condition of patients with atrial fibrillation gradually recovered. Conclusion The diagnosis of ASRI requires enhanced CT and DSA examination due to its rare incidence and the high misdiagnosis rate in clinic.Early diagnosis and use of interventional thrombolytic therapy method is a feasible and effective treatment method.

Objective To observe the protective effect of the separate zinc gluconate oral and combined of Salvia injection on whole blood metal ion of calcium,magnesium,iron,copper and zinc concentration in noise-induced rats.Methods 50 female SD rats were randomly divided into a control group,a noise group,a zinc gluconate noise group (plus zinc group),a Salvia injection noise group (plus Salvia group) and a Zinc gluconate oral liquid and Salvia injection noise group (combined group),with10 rats in each group.Except the control group did not expose to noise,the rest groups were continuously exposed to high frequency steady noise for two weeks.Each group was compared for the concentration differences of whole blood metal ion of calcium,magnesium,iron,copper and zinc after the intervention of noise.Results ① In each group at the comparison of the calcium ion concentration: Calcium ion concentration of the control group(1.25± 0.16)mmol/L and the combination group(1.27 ± 0.10) mmol/L was significantly lower than the noise group (1.42 ± 0.18) mmol/L.The rest groups compared to each other were not statistically significant.②Magnesium ion concentration was highest in the noise group (1.53 ± 0.10)rmtmol/L),and lowest in the control group (130 ± 0.29) mmol/L,and the noise group was significantly higher than that of the control group.The mean of magnesium ion concentration in plus zinc group (1.42± 0.27) mmol/L,plus Salvia group (1.38± 0.15) mmol/L and combined group(l.37±0.11)mmol/L were lower than the noise group,but the difference was not significant (P＞0.05).③ The iron ion concentration of the noise group (5.47± 1.29)mmol/L was significantly lower than the other four groups (P＜0.05).The control group,plus zinc group,plus Salvia group,the combined group showed no significant differences.④ Whole blood copper ion concentration of the noise group (16.69 ± 4.18) μmol/L was significantly lower than the control group (21.53 ± 3.78) μmol/L and the combination group(19.53± 1.92)μmol/L with a statistical difference; compared with the control group,the concentration of copper ions in plus zinc group(16.19± 1.93)mμol/L was significantly lower (P＜0.05).⑤The whole blood zinc ion concentration in the noise group (50.83±7.99)μmol/L was significantly lower than the other groups,zinc ion concentration in the plus Salvia group (53.87±6.77)μmol/L was significantly lower than the control group (63.86± 8.83) μmol/L; the whole blood zinc ion concentration showed no difference between the plus zinc group (54.81 ± 5.90) μmol/L,plus Salvia group and combined group (59.21 ± 3.90) μmol/L.Conclusion Combined zinc gluconate oral solution and Salvia injection had protective effect on whole blood metal ion concentration affected by noise.The protection effect of zinc gluconate oral solution and Salvia injection combination was stronger than any individual.

To study the multidrug resistance activity of 1-alkyl-2-acetyl-1, 2, 3, 4-tetrahydroisoquinoline derivatives. Methods: A series of novel tetrahydroisoquinoline derivatives bearing at C-1 position a carbon chain derived from fatty acids were prepared through the Bischler-Napieralski cyclization reaction. Their multidrug resistance (MDR) reversal cancerous multidrug resistance activities were evaluated against K562 and K562/DOX cell lines in vitro by MTT assay with verapamil as a control. Results and Conclusion: The structures of these tetrahydroisoquinolines were confirmed by extensive spectroscopic methods(1H NMR, MS, IR and elemental ana-lyses). MDR results showed that compounds 7 and 10 exhibited moderate reversal activities, and were slightly less potent than those of verapamil against K562 cell line. It is believed that compounds 7 and 10 have MDR activity.
