Objective To study the relationship between Noble grade and distribution of myocardial bridge and atherosclerosis. Methods The clinical data of 192 patients with myocardial bridge diagnosed by coronary artery angiography were retrospectively analysed.The clinical symptoms,electrocardiographic and echocardiographic findings were analysed to explore the relationship between Noble grade and distribution of myocardial bridge and atherosclerosis,and the outcomes of medical treatment were also investigated. Results The positive rate of myocardial bridge detected by coronary artery angiography was 10.2%,which was usually observed in the middle part of left anterior descending coronary artery.All the patients with grade 3 of Noble grade experienced chest pain or palpitation,43.8% had ischemic ST-T changes on electrocardiogram,and 37.5% had abnormal segmental ventricular wall on echocardiography.However,patients with Noble grade 1 and 2 did not have ischemic ST-T changes on electrocardiogram or abnormal segmental ventricular wall on echocardiography.The prevalence of atherosclerosis in proximal coronary artery of myocardial bridge was significantly higher than those of mural coronary artery and distal coronary artery(P

0.05).Compared with non-myocardial infarction group,the prevalence of normal segmental ventricular wall motion and ejection fraction in myocardial infarction group was significantly lower,while those of akinesia and paradoxical motion were significantly higher(P

Objective To investigate the role of apelin-13, a vasoactive peptide, in rat myocardial ischemia-reperfusion injury in vivo and explore its signal transduction pathway. Methods Rats were randomly divided into control group (n=10) and Apelin-13 group (n=15), and in vivo models of rat myocardial ischemia-reperfusion injury were established. Normal saline (control group) or Apelin-13 (Apelin-13 group) was administered intravenously 5 min before reperfusion. TTC and Evan's blue staining were used to determine the infarction size (IS) and area at risk (AAR), apoptotic cells were quantified by TUNEL method, and the expression of ERK1/2 was determined by Western blotting. Results IS/AAR and apoptosis index of Apelin-13 group were significantly lower than those in control group [(38.33±12.95) % vs (52.61±11.00)% and (0.21±0.02) vs (0.31±0.05)](P <0.05). The expression of p-ERK1/2 in Apelin-13 group was significantly increased than that in control group [(1.15±0.16) vs (0.63±0.07)](P < 0.05). Conclusion Apelin-13 may protect rat hearts from in vivo ischemia-reperfusion injury, reduce infarction size and attenuate myocardial apoptosis, which may be mediated by the activation of ERK1/2 MAPK signal transduction pathway.

Objective]To compare the efficacy and safety of retroperitoneal laparoscopic intrasinusal pyelolithotomy (RLIP) and percutaneous nephrolithotomy(PCNL)in the treatment of solitary renal pelvic stone.[Methods]From March 2012 to September 2016,101 patients with solitary renal pelvic stone,divided into RLIP group(n=46)and PCNL group(n=55),were retrospectively analyzed to compare the difference between the two groups in clinical curative effect.[Results]There was no difference between the two groups regarding age,sex,stone side and stone size. Although the operative time was significantly longer,the stone-free rate in the RLIP group was significantly higher than that in the PCNL(P < 0.05). The postoperative complication of urinary tract infection was lower in the RLIP group (P < 0.05),however ,no significant difference was found in postoperative discharge time ,fever (>38.5℃)and the decrease values of hemoglobin and glomerular filtration rate.[Conclusion]Compared to PCNL,RLIP was more efficient and slight safer in the management of solitary renal pelvic stone ,and had a certain value for generalization in clinic.

Objective To study the effects of moderate hypothermia on cerebral glucose and ATP contents andmitochondrial succinate dehydrogenase (SDH) activity in neonatal rats with hypoxic-ischimic brain damage (HIBD).Methods Seven-day-old Sprague-Dawley rat pups were subjected to ligation of the left carotid artery followed by exposureto hypoxia environment of 8 % O2 for 2 h, then they were randomly assigned into normothermic recovered group ( Ingroup) and moderate-hypothermic recovered group (IH group). The sham-operated rats which were used as the controlwere assigned into the normothermic control group (NC group) and moderate-hypothermic control group (HC group).The contents of glucose and ATP and activity of mitochondrial SDH were assayed at 0, 2, 6, 24, 48, 72 h after HIBD.Results The cerebal glucose contents in the IN and IH groups were significantly lower than those of the NC and Hcgroups 0 h after HIBD. Two hours after HIBD, the glucose content recovered to norhal level. The concentration of ATPand activity of SDH in the IN group decreased first, then they recovered gradually and reached a peak 72 hours afterHIBD. After 6 hours or 2 hours of HIBD, the ATP content or SDH activity of the brain in the IH group weresignificantly higher than those in the IN group. The ATP concentration was closely related to the SDH activity ( r =0.515, P <0.01). Conclusions Moderate hypothermia might protect brain tissue by inhibiting the decrease of SDHactivity and increasing the synthesis of ATP.

Objective To clone and express a high mobility group box 1(HMGB1)protein of Schistosoma japonicum(Main-land strain)and analyze its function. Methods The DNA fragment of open reading frame encoding Sj HMGB1 protein was ampli-fied by RT-PCR from the mRNA of S. japonicum worms,then it was subcloned into the expression vector pET28a(+)to form the recombinant expression plasmid SjHMGB1-pET28a. The recombinant expression plasmid was transformed into the component E. coli BL21(DE3),and the tranformant containing recombinant expression plasmid was induced with IPTG to express the recombi-nant protein SjHMGB1. The recombinant SjHMGB1 protein was purified by affinity chromatography with nickel chelating affinity chromatography agarose gel. The Gel retard experiment and animal immunization were performed to analyze the DNA binding ca- pacity and the immunologic property of recombinant SjHMGB1. The expression levels of HMGB1 in different life cycle stages of S. japonicum were analyzed by Western bloting and RT-PCR. Female ICR mice were immunized with the recombinant SjHMGB1 pro-tein and infected with 45±2 cercariae of S. japonicum after three immunizations. Forty-two days post-infection,the worms and eggs of S. japonicum were recovered from the portal vein and liver tissue,respectively. The worm and egg reduction rates were calculat-ed respectively. Results A 530 bp of specific DNA fragment was amplified from mRNA of S. japonicum by RT-PCR,which was the open reading frame(ORF)encoding SjHMGB1protein confirmed by DNA sequencing analysis. The recombinant expression plasmid SjHMGB1-pET28a was constructed by cloning the ORF of SjHMGB1 into a expression vector pET28a(+). The bacterium transformants containing the recombinant plasmid expressed a soluble recombinant protein about 28 kDa after induced by IPTG, and the recombinant SjHMGB1 protein was purified by nickel chelating affinity chromatography. The gel retard experiment showed that the recombinant SjHMGB1 protein could bind to both supercoiled DNA and linear DNA,and the recombinant protein immu-nized mice produced high titers of antiserum IgG. Western bloting indicated that the recombinant SjHMGB1 protein was recognized specifically by the S. japonicum-infected mice serum. Above results showed that the recombinant SjHMGB1 protein possessed both functional activity and immunogenicity as the natural protein. RT-PCR and Western blot results showed that SjHMGB1 was abun-dantly expressed in the adult and egg stages whereas barely detectable in the cercaria stage. The immune protection experiment showed that the recombinant SjHMGB1 induced mice to produce high titers of specific antibody IgG but failed to conduct an effec-tive immune protection against S. japonicum. Conclusion The gene encoding HMGB1 from S. japonicum and the soluble recombi-nant SjHMGB1 protein with natural functional activity are obtained,and the recombinant SjHMGB1 has a high immunogenicity but is not able to induce an effective immune protection against S. japonicum.
