Objective To investigate the expressions of intermedin /adrenomeduliin 2 (IMD/AM2) and its receptor calcitonin receptor-like receptor (CRLR) in the kidney of rats after renal ischemia reperfusion injury(IRI). Methods Male Wistar rats were divided randomly into two groups: sham group and operation group. Renal IRI model was induced by clamping both renal arteries. Blood and kidney were harversted at 0 h, 6 h, 12 h, 24 h, 48 h, 72 h after reperfusion, respectively. Renal histological changes were semi-quantitated. Expressions of IMD and CRLR in the kidney were detected by Western blot, and the content of IMD in serum was measured by radioimmunity at 12 h, 48 h, 72 h after repeffusion. Results Kidneys of renal IRI model rats displayed significant pathologic changes, and the changes were much severer at 48 h after reperfusion. The expressions of IMD and CRLR in kidney were significantly up-regnlated at 12 h, 48 h, 72 h after renal IRI (P<0.01). The level of IMD in serum increased at 12 h, 48 h, 72 h after renal IRI (P<0.05). Conclusion The expressions of IMD and its receptor are up-regulated in the kidney after renal IRI, which may participate in the pathophysiological changes induced by renal IRI.

BACKGROUND: Currently, the researches on knee plaster immobilization paralysis animal models are popular in the world, but there are some insufficiencies with the knee paralysis animals, for example, poor animal selection, inappropriate plaster selection and pure gypsum instability, which affect the subsequent results.
OBJECTIVE: To establish a rabbit model of knee paralysis by the knee fixation with plaster casts and wire.
METHODS: A total of 20 New Zealand white rabbits were randomly divided into two groups. Models of right knee paralysis were established and fixed by plaster casts and wire. Normal controls were considered as the control group. At 8 weeks after fixation, right knee and pathologic histology were observed in the right knee.
RESULTS AND CONCLUSION: The knee joints were translucent, smooth, and shiny, without the cartilage defect in the control group, and the cartilaginous elasticity and rigidity were good, and the arrangement of chondrocytes was normal. There were no inflammatory infiltrations in the articular capsule of the normal rabbits. In the model group, the knee joint was matt and opaque. Articular cartilage became thin, and showed poor elasticity. The cartilages were degenerated. Articular surface was rough, and had defects. There were smal amount of joint fluid or no joint fluid. Cartilage cel s shrank or disappeared, and the number of cartilage cel s reduced with degeneration and necrosis. Subchondral bone became sclerosis with trabecular bone of hyperplasia. The arrangement of cartilage cel s was disordered, with hyalinization and synovial vil ous hypertrophy. Cel clustering phenomenon was seen. There were a large number of lymphocytes, plasma cel s and neutrophil infiltration in cartilages. The typical pathological changes of the knee paralysis present in the rabbit cartilage. These results demonstrate that the rabbit model of knee paralysis can be successful y established by using fixation method with plaster casts and wire, which has the advantages of simple operation, strong fixation and no injury.

Objective To investigate the effect of video -assisted thoracoscopic surgery (VATS)and conventional thoracotomy in treatment of thoracic esophagus cancer,to provide the reference for clinical.Methods 90 cases of thoracic esophageal cancer in our hospital from January 2012 to January 2015 were chosen as the research subjects.They were randomly divided into observation group(application of VATS treatment)and the control group (application of traditional open chest surgery).The quantity difference,chest drainage,hospitalization time,complica-tions,recovery conditions and other indicators of bleeding were compared in the two groups.Results The operation time of the observation group[(267.6 ±76.5)min]was shorter than that of the control group[(324.4 ±87.6)min]. The amount of intraoperative bleeding[(235.3 ±79.5)mL],drainage volume[(327.5 ±95.2)mL]of the observation group were less than the control group[(398.2 ±98.3)mL and (752.6 ±156.4)mL].Postoperative hospitalization time[(12.2 ±3.2)d]of the observation group was shorter than the control group[(15.8 ±4.4)d].The differences were statistically significant (t =3.276,8.644,15.575,4.439,all P <0.05).There were no significant differences between two groups in recurrence and metastasis rate,mortality rate and total survival rate (χ2 =0.123,0.212, 0.212,all P >0.05).The complication rate of the observation group was lower than that of the control group,the difference was statistically significant (χ2 =4.865,P <0.05).Conclusion In the treatment of thoracic esophageal carcinoma,VATS and conventional thoracotomy surgery has good effect,and VATS has small injury,less complication.

Aim To study the effect of tetrandrine ( Tet ) on proliferation of MCF-7 breast cancer cells and the possible mechanism underlying this biological process. Methods CCK-8, flow cytometric and Western blot were introduced to analyze the effect of Tet on proliferation and apoptosis in MCF-7 cells.Re-al-time PCR and/or Western blot assay were employed to detect the effect of Tet on expression of IGFBP-5 , p53 and MDM2.CCK-8 and recombinant adenovirus were utilized to determine the effect of IGFBP-5 on the proliferation inhibitory effect of Tet .Western blot assay was introduced to evaluate the effect of IGFBP-5 on p53 which was induced by Tet .Results Tet inhibited the proliferation , arrested cell cycle at G 1 phase and decreased the expression of PCNA concentration dependently in MCF-7 cells.Meanwhile, Tet increased the percentage of apoptotic cells , the level of Bad and reduced the level of Bcl-2.Tet increased the expres-sion of IGFBP-5 either mRNA or protein , over-expres-sion of IGFBP-5 enhanced the anti-proliferation activity of Tet in MCF-7 cells, but knockdown of IGFBP-5 at-tenuated this effect of Tet .Tet increased the level of p53 and decreased that of MDM2, and exogenous IG-FBP-5 enhanced the effect of Tet on p53 and MDM2, respectively .Conclusion Tet can inhibit the prolifer-ation of MCF-7 cells, and this activity is partly media-ted by increasing the function of p 53 signal , which may be triggered by the Tet-induced IGFBP-5.

BACKGROUNDCoronary computed tomographic angiography (CCTA) has been widely used in patients who are at intermediate risk for having stable coronary artery disease (SCAD), and 2013 European Society of Cardiology Guidelines on the Management of SCAD (2013G) recommended the appropriate application of CCTA. However, 2013G has not been subjected to systematic analyses for subsequent impact on clinical practice.

METHODSA total of 5320 patients suspected with SCAD were enrolled and scheduled for CCTA from March 2013 to September 2014. For each patient, pretest probability of SCAD was calculated according to updated Diamond-Forrester model (UDFM). Appropriate CCTA or appropriate stress test was determined as described in the 2013G. A generalized estimating equation model was used to determine the trends in the half-monthly rate of appropriate CCTA.

RESULTSOverall, only 61.37% of patients received appropriate CCTA, and there was insignificant change over time (P = 0.8701). The application of CCTA in patients who should have had a stress test accounted for most of the inappropriate CCTA before (22.29%) or after (19.98%) the publication of the 2013G. In all patients or any subgroup, no significant change in the adjusted half-monthly rate of appropriate CCTA was found after the publication of the 2013G (odds ratio, 1.002; 95% confidence interval, 0.982-1.021; P = 0.8678).

CONCLUSIONSThese findings suggest that the 2013G have not, to date, been fully incorporated into clinical practice, and the clinical utilization of CCTA remains unreasonable to some extent.

BACKGROUNDEarly onset severe preeclampsia is a specific type of severe preeclampsia, which causes high morbidity and mortality of both mothers and fetus. This study aimed to investigate the clinical definition, features, treatment, outcome and risk factors of early onset severe preeclampsia in Chinese women.

METHODSFour hundred and thirteen women with severe preeclampsia from June 2006 to June 2009 were divided into three groups according to the gestational age at the onset of preeclampsia as follows: group A (less than 32 weeks, 73 cases), group B (between 32 and 34 weeks, 71 cases), and group C (greater than 34 weeks, 269 cases). The demographic characteristics of the subjects, complications, delivery modes and outcome of pregnancy were analyzed retrospectively.

RESULTSThe systolic blood pressure at admission and the incidence of severe complications were significantly lower in group C than those in groups A and B, prolonged gestational weeks and days of hospitalization were significantly shorter in group C than those in groups A and B. Liver and kidney dysfunction, pleural and peritoneal effusion, placental abruption and postpartum hemorrhage were more likely to occur in group A compared with the other two groups. Twenty-four-hour urine protein levels at admission, intrauterine fetal death and days of hospitalization were risk factors that affected complications of severe preeclampsia. Gestational week at admission and delivery week were also risk factors that affected perinatal outcome.

CONCLUSIONSEarly onset severe preeclampsia should be defined as occurring before 34 weeks, and it is featured by more maternal complications and a worse perinatal prognosis compared with that defined as occurring after 34 weeks. Independent risk factors should be used to tailor the optimized individual treatment plan, to balance both maternal and neonatal safety.
