Summary: Receptor mediated gene delivery is a new gene transfer strategy. Asialoglycoprotein receptor (ASGP-R), the receptor of asialoorosomucoid (Asor), is specially expressed on the surface of hepatocyte. In this paper, the nuclide 131I was combined with Asor to form a kind of soluble nuclide-protein complex, which can be specifically endocytosed into hepatocyte by ASGP-R. After intravenous injection of the complex into experimental animals, the deposition of Asor in vivo and the targeting quality of hepatocyte was detected by ECT. This research testified the feasibility of targeting Asor complex delivery to hepatocyte mediated by ASGP-R in vivo, and provided foundation for the genetic diagnosis and gene therapy of hepatic cell-related diseases.

OBJECTIVETo search for an optimum method for testicular prothesis implantation in the treatment of testis loss.

METHODSWe retrospectively analyzed the surgical methods and outcomes of 53 cases of terminal prostate cancer and 4 cases of unilateral testicular torsion treated by implantation of testicular prothesis with the polypropylene mesh.

RESULTSThe 57 male patients all received testicular prothesis with the polypropylene mesh. All the patients were satisfied with the appearance and size of the scrotum after surgery. No scrotal hematoma, prosthesis infection, or autoimmune disease occurred postoperatively.

CONCLUSIONTestis loss is not a rare condition clinically, for the treatment of which surgical implantation of testicular prothesis with the polypropylene mesh can achieve both a fine tissue compatibility and a desirable scrotal appearance.

Objective To understand the current situation of occupational exposure and occupational safety attitudes among nursing students in Kunming Medical University, and to find effective interventions to improve nurses' occupational safety,and to reduce occupational exposure.Methods 854 students in Kunming Medical University were investigated by a questionnaire survey, including Demographic characteristics, Occupational exposure conditions, Occupational safety attitude and Gathers, quit intention . The correlations between occupational safety attitudes and occupational exposure were analyzed with Simple Linear Correlation.Results There were 94.30%female respondents,and only 5.70%male respondents.The average age of respondents was 22.52±2.90 years. The Simple Linear Correlation analysis showed that correlation between Negative attitude and occupational exposure was positive correlated, the occupational exposure and Support from managers, and Optimistic were negative correlation ( <0.05) .Conclusions Occupational safety and attitude are related to occupational exposure. Nursing students should apply standardized operation to improve the professional quality and ability. Schools should strengthen the education of occupational protection for nursing students. Hospital management should regularly organize nurses to study occupational exposure protection knowledge,give full affirmation of the nurse's achievements in the work, and offer certain reward appropriately.

Aim To observe whether the activation of aldehyde dehydrogenase 2 ( ALDH2 ) can protect a-gainst diabetes induced liver injury in rat model, and analyze the role of JNK pathway in the liver protection induced by activation of ALDH2 . Methods All male SD rats were randomly divided into three groups: nor-mal control group ( Con ) , diabetes group ( DM ) and ethanol + diabetes group ( EtOH + DM ) . After 8 weeks, the fasting blood glucose ( FBG) level, glyco-sylated hemoglobin ( HbA1c) level, serum AST and ALT levels were measured. The changes of hepatic pa-thology were observed by hematoxylin and eosin ( HE) staining method. The protein expressions of ALDH2, JNK and p-JNK in liver tissue were measured. Result Compared with control group, in DM group, the lev-els of FBG and HbA1c, serum AST and ALT levels were increased significantly. The structure of liver mor-phology was destroyed, disarranged and unclear, the hepatocyte was swollen, and a large number of inflam-matory cells were infiltrated. ALDH2 protein expres-sion was decreased, while the expressions of JNK, p-JNK and the ratio of p-JNK/JNK were increased. Com-pared with DM group, in EtOH+DM group, the levels of FBG and HbA1c, serum AST and ALT levels were decreased. The expression of ALDH2 protein was in-creased, accompanying with the decrease of JNK, p-JNK protein expressions and the ratio of p-JNK/JNK. Conclusion Activation of ALDH2 can protect the liv-er against diabetes induced liver damage in rat model, which may be relevant with inhibiting the JNK path-way.

ObjectiveTo evaluate magnesium sulfate and compound polyethylene glycol electrolyte in bowel preparation before capsule endoscopy.MethodsA total of 81 patients were randomly divided into two groups.Group A (n =41 ) received compound polyethylene glycol electrolyte,and group B (n =40) received magnesium sulfate combined with compound polyethylene glycol electrolyte. Positive detection rate,intestinal preparation score,the incidence of capsule retention and solution quality,liver and kidney function were compared between those two groups.ResultsThe positive detection rates of capsule endoscopy were 65.9％ (27/41) in group A and 62.5％ (25/40) in group B,which were nonsignificantly different (x2 =0.099,P ＞ 0.05).The intestinal preparation scores of 19 patients in group A were ≤4 and those of 22 patients were ≥6,while those of 28 patients in group B were ≤4 and of 12 patients were ≥6,which were significantly different (x2 =4.653,P ＜ 0.05). The rates of capsule retention of group A and B were 2.4％( 1/41 ) and 5.0％ (2/40) respectively,which were not significantly different (x2 =0.372,P ＞ 0.05 ).Obvious abdominal pain,nausea or vomitting occurred in no patients of the two groups.There was no difference in electrolyte level or liver and kidney function between those two groups (P ＞ 0.05 ).ConclusionMagnesium sulfate combined with compound polyethylene glycol electrolyte is applicable for the bowel preparation before capsule endoscopy.
