Objective To investigate the application and effect on the performance training of adverse events, and to improve the quality of nursing teaching. Methods Totally 120 new graduate nurses in our hospital were randomly divided into study group(n=60)and control group(n=60). Study group used performance training while control group used traditional training mode and evaluation was made from the adverse event knowledge score , number of adverse events and satisfaction degree of stu-dents. Results Adverse event knowledge score of study group (9.57±0.563) was obviously higher than that of control group(84.90±3.245). Satisfaction degree of students in study group(9.57±0.563) was higher than that of control group(7.35 ±0.917), with statistical differences(P<0.01). Number of ad-verse events(n=3) was obviously lower in study group than in control group(n=15), with statistical differences(P<0.01). Conclusion In adverse events teaching, performance training can be helpful in arousing students' interests in learning. Experiences of self-examination and self-correction also make the students have a deep impression on knowledge, which improves the quality of adverse events teaching and reduces the incidence of adverse events in the new graduates.

Many reports have documented a role of insulin and insulin-like growth factor 1 (IGF-1) as growth factors in many cancers. The sequence and structure of insulin receptor (IR) and IGF receptor (IGF-1R) are highly similar. Both receptors are overexpressed in leukemia cells.Studies indicate that insulin can enhance the signal of the phosphoinositide 3-kinase/Akt pathways by activating IR or IGF-1R or hybrid IR/IGF-IR receptors, resulting in the proliferation of leukemia cells. High concentration of insulin may inhibit the growth of leukemia cells, the mechanism of which remains to be unclear. Inhibiting IR and IGF-IR can diminish the proliferation of leukemia cells. Therefore, the assumption of IR/IGF-1R as a potential therapeutic target in leukemia appears reasonable. This article summarizes the recent advancement associated with the signaling pathway of insulin effecting the proliferation of leukemia cells.

Objective To explore the application value of transient elastography (TE)by using transient elas-tography(FibroScan)for the noninvasive diagnosis of hepatic fibrosis and steatosis by measuring liver stiffness (LS)and controlled attenuation parameter (CAP)in the preschool children in Shanghai for their health check - up. Methods A total of 410 children,who underwent health screening in Xinhua Hospital,Affiliated to Shanghai Jiaotong University School of Medicine,from April to November 2017 were collected. LS and CAP values were obtained by the FibroScan device with M - probe. The differences in LS and CAP values between different genders were analyzed,as well as the in-fluencing factors for LS and CAP values. Results A total of 410 preschool healthy children were enrolled. The success rate of valid TE measurements by M - probe in the participating children was 96. 5％ . The LS and CAP values were (3. 22 ± 0. 86)kPa and (176. 74 ± 20. 84)dB/ m,respectively. LS and CAP values didn′t differ significantly in gender (all P > 0. 05). In univariate analysis,the CAP values were significantly associated with height (r = 0. 112,P =0. 026),weight(r = 0. 145,P = 0. 004),body mass index(r = 0. 114,P = 0. 023),waist circumference(r = 0. 178,P =0. 000)and hip circumference(r = 0. 148,P = 0. 003). Conclusions FibroScan equipped with M - probe is feasible for LS and hepatic steatosis measurement in preschool children.

Objective To evaluate the follow-up results of patients with cervical intraepithelial neoplasia Ⅲ(CIN Ⅲ)after surgical treatment.Methods A retrospective analysis of consecutive patients with CIN Ⅲ after surgical treatment between Jan 1st,1999 and Jun 30 th,2004 was performed.The follow- ups of the patients after surgical treatment were assessed.Results In the follow-up of patients with CINⅢ after surgical treatment,the rate of abnormal cytology was 9.3%.The rate of follow-up was higher in patients with cervical conization than in patients with initial hysterectomy and in patients of the oncological group than of the non-oncological group.The rate of follow-up was lower in patients over 40 years old.There was no difference in the residential areas of the patients.Conclusions Cytological follow-up of patients with CINⅢ after operation is varied.The rate of follow-up is lower in patients over 40 years old,in patients having initial hysterectomy and in patients of the non-oncological group.The rate of follow-up is associated with the knowledge about CIN of both surgeons and patients.

Objective To exclude false positivities in detection of IgM antibodies against hepatitis E vires of genotype 4 (HEV-4) using a truncated immunodominant polypeptide of HEV open reading frames (ORF2). Methods The recombinant ORF2 immunodominant polypeptide corresponding to amino acids (AA) 459-607 and a truncated polypeptide corresponding to AA 472-607 were separately applied to coat ELISA plates. Anti-HEV IgM from 35 serum samples with HEV RNA positive, 69 serum samples from healthy individuals and 117 clinically suspicious HEV RNA positive serum samples was detected by an indirect ELISA and was confirmed by western blot in protein level and RT-PCR detecting in RNA level. Results Western blot analysis showed that the sera from HEV patients reacted with the dimmer of peptide 459-607, but they didn't react with the monomer and peptide 472-607. The ELISA showed that all 35 serum HEV RNA positive samples reacted with peptide 459-607 but not with peptide 472-607 and none of the 69 serum samples from healthy individuals reacted with either polypeptide. Among 117 chnically suspicious HEV RNA serum samples, 5 samples reacted simultaneously with both polypeptides. But the difference between 450 nm absorbance (A450) value was less than 0. 5. Western blot analysis demonstrated that all the 5 serum samples were anti-HEV IgM- negative. The 5 serum samples was detected negative by RT-PCR, indicating that the false pesitivities were caused by non-specific absorption. Conclusions ORF2 peptide 459-607 may be used to detect anti-HEV lgM efficiently. The false positivities caused by non-specific absorption can be largely excluded according to the difference between 45Ohm absorbance (A450) value when serum reacts with both polypeptides.
