Objective To evaluate the role of the expression of heat shock protein 70 (HSP70) and heme oxygenase-1 (HO-1) in the reduction of renal ischemia-reperfusion (I/R) injury by ischemic postconditioning in tats.Methods One hundred and forty healthy male SD rats weighing 250-280 g were randomized into 4 groups ( n = 35 each) : sham operation group (S group) ; I/R group; ischemic postconditioning group (IPo group); quercetin (an inhibitor of HSP) + ischemic postconditioning group (Q + IPo group). Renal I/R was produced by clamping bilateral renal pedicels for 45 min followed by reperfusion. In group S, bilateral kidneys were only exposed through a midline incision but their- pedicels were not clamped. In IPo and Q + IPo groups, 45 min ischemia was followed by three 10 s episodes of ischemia at 10 s intervals for reperfusion and in addition intraperitoneal quercetin 100 mg/kg was injected at 1 h before ischemia in group Q + IPo. Blood samples from hearts were obtained at 0, 1, 3, 6, 12, 24 and 48 h of reperfusion (T0-6) and the rats were then sacrificed and kidneys removed to detect the expression of HSP70 and HO-1 mRNA and protein in renal tissues. The blood samples obtained at T3 were used to determine serum creatinine (Cr) and urea nitrogen (BUN) concentrations and the expression of caspase-3 mRNA . The apoptosis in the renal tissues was detected using TUNEL and apoptotic index ( AI) was calculated. Microscopic examination was performed with light microscope. Results Compared with group S, the serum Cr and BUN concentrations and AI were significantly increased at T3,the expression of caspase-3 mRNA was up-regulated at T3, and the expression of HSP70 and HO-1 mRNA and protein was up-regulated at T0-6 in the other groups (P ＜ 0.05) . Compared with group I/R, the serum Cr and BUN concentrations and AI were significantly decreased at T3, the expression of caspase-3 mRNA was down-regulated at T3, and the expression of HSP70 and HO-1 mRNA and protein was up-regulated at T1-5 in group IPo ( P ＜ 0.05) . Compared with group IPo, the serum Cr and BUN concentrations and AI were significantly increased at T3, the expression of caspase-3 mRNA was up-regulated at T3, and the expression of HSP70 and HO-1 mRNA and protein was down-regulated at T1-5, in group Q + IPo ( P ＜ 0.05) . The microscopic examination showed that the renal I/R injury was significantly attenuated by ischemic postconditioning and the degree of injury in group IPo was similar to that in group I/R. Conclusion The expression of HSP70 and HO-1 is involved in the reduction of renal I/R injury by ischemic postconditioning in rats.

OBJECTIVETo observe the clinical efficacy differences among warming-promotion acupuncture, regular acupuncture and psychological care for post-earthquake depression.

METHODSNinety cases of post-earthquake depression in Gansu province were randomly divided into a warming-promotion acupuncture group, a regular acupuncture group and a care group, 30 cases in each one. The psychological treatment was applied in the care group; the regular acupuncture at Baihui (GV 20), Sishencong (EX-HN 1)), Fengchi (GB 20), Shenmen (HT 7), Yang-lingquan (GB 34), Taichong (LR 3) and Sanyinjiao (SP 6) was used in the regular acupuncture group; based on the treatment of regular acupuncture group, the warming-promotion acupuncture was applied in the warming-promotion acupuncture group, once a day. Ten days were taken as one course with an interval of two days between two courses. Totally 3 treatment courses were completed. The Hamilton depression (HAMD) scale before and after treatment in each group was observed while the efficacy was analyzed.

RESULTSAll three treatments were effective for depression. The total cured rate was 86.67% (26/30) in the warming-promotion acupuncture group, which was obviously superior to 50.00% (15/30) in the regular acupuncture group (P < 0.01) and 33.33% (10/30) in the care group (P < 0.001). After the treatment, the score of HAMD was all reduced in three groups, in which the effect in warming-promotion acupuncture group was superior to that in the regular acupuncture group and care group (9.02 +/- 2.37 vs 10.73 +/- 2.28 and 11.05 +/- 2.01, P < 0.05, P < 0.01).

CONCLUSIONThe warming-promotion acupuncture has positive effect on post-earthquake depression, which has special effect and is worthy of clinical generalization and application.

Objective To evaluate the value of prenatal ultrasound in the interrupted aortic arch (IAA), and analyze the reasons of misdiagnosis and improve diagnostic ratio of this kind of defects. Methods Ultrasonic characteristics were analyzed in 16 fetuses with aortic arch anomalies, which were compared with ultrasound image and autopsy results of the normal fetus. The relativity of fetal IAA and abnormal chromosome was also analyzed. Results Among the 16 cases, 15 cases were confirmed by anatomy and the accuracy of ultrasound diagnosis was 94% (15/16), of which one case was serious constriction of aortic arch, one case was error type, three cases were obtained explicit type due to unsatisfactory results of prenatal ultrasound. The coincidence rate of ultrasonic type was 73% (11/15). All of the corrected diagnosed cases were detected with ventricular septal, of which 5 cases were detected with complete endocardial cushion defect, 9 cases were found extra cardiac malformations. Among the 7 karyotype check cases, 3 cases were diagnosed with Trisomy 18, 1 case Trisomy 13, while the rest 3 cases normal. The incidence rate of Trisomy 18 was 43 % (3/7). Conclusions Prenatal ultrasound shows a high accuracy in diagnosing fetal interrupted aortic arch (IAA ), but there’s a need to be improved in explicit typing. It is difficult to identify fetal interrupted aortic arch (IAA) and serious constriction of aortic arch (COA). The incidence rate of Trisomy 18 in the abnormal chromosome of fetal IAA is high.
