In order to summarize the experience in physician recruitment and training process,an investigation was carried out on young physicians recruited from campus from 2007 to 2011.The results showed that the assessments of departments of the young physician's on theirs' medical ethics,professional values,theoretical knowledge,clinical competence and other aspects were higher.This indicated that these young physicians have higher overall quality.In addition,compared with the above-described abilities,the results also showed that the assessments on theirs' foreign language oral communication skills,research capacity,innovation capability,and so on,were lower.Therefore the hospital should continue to increase assessments to the candidates during the campus recruitment stage,and to develop targeted training plans so as to strengthen the ability of young physicians continually.

To promote sustainable development of the hospital,Peking University Cancer Hospital adopted a series of measures to help advance the health professionals,which include a favorable recruiting and training systemsto attract high-level talents,recruit qualified graduates,supporting outstanding young asholars to studying abroad,etc.. These measures have achieved remarkable results,and have in turn greatly promoted the continuous development of medical practice and scientific research work of the hospital.

Objective To explore the correlation between resistins rs2161490and rs1423096 genotype with type 2 diabetes mellitus (T2DM)in Guangdong.Methods Collected 178 blood of newly diagnosed T2DM in the Second Affiliated Hospital of Guangzhou Medical University from January 2015 to November 2015 as the patient group and 192 blood of healthy physi-cal examination as the control group.Analysis of the two groups of gene distribution frequency was to reach the genetic equi-librium,comparative two gene loci frequencies of resistin rs2161490 and rs1423096 in case group and control group was sta-tistically significant,and compared the distribution frequency of rs2161490 locus T→C and rs1423096 locus A→G between the patient group and the control group.Then made a logistic regression analysis:analysing the risk two loci each genotype of resistin rs2161490 and rs1423096 to T2DM,adjust of the gender and age,and the changes of the risk of the two variables. Comparative blood lipids biochemical indexes between case group and the control group,mode the correlation analysis be-tween TG,CHOL,HDL-C and LDL-C levels of serum lipids in patients with rs2161490 and rs1423096 each genotypewere performed.Results The sample was consistent with Weinberg Hardy’s law of inheritance,which was representative of the population,comparing two gene loci frequency of resistin rs2161490 and rs1423096 of case group and control group:com-parinng CT,TT,CC of rs2161490 genotype,there was no statistically significant difference (P=0.834,>0.05),and com-parinng AA,AG,GG of rs2161490 genotype,there was no statistically significant difference (P=0.960,>0.05).Each gen-otypes with T2DM risk analysis,there was no statistically significant difference(P>0.05).Adjusting the risk change after the two variables,gender and age,there was no statistically significant difference (P>0.05);TG,CHOL,HDL-C and LDL-C in each of the genes expression levels correlation analysis,there was no statistically significant difference (P>0.05).Con-clusion Analysis results showed that the frequency of two loci all genotypes in the case group and control group were no statistical significance (P>0.05).The risk of two loci gene type of rs2161490 with rs1423096 and type 2 diabetes were be-fore and after the covariate adjustment had no statistical significance (P>0.05 ).Each genotype of rs2161490 with rs1423096 and lipid levels had no statistical significance (P>0.05).Thus infer that two genotypes is not risk for type 2 dia-betes genes in guangdong area.

Objective To evaluate the effects and safety of uterine artery embolization for uterine leiomyoma. Methods Total of 185 patients with uterine leiomyoma were treated by UAE. They were followed for one to 6 years to observe the changes of leiomyoma size and improvement in clinical symptoms. Ovarian function was evaluated in 44 cases. Results Bilateral embolization of uterine arteries was performed in 185 patients. Follow-up of 1 ～6 years for 292 leiomyoma indicated that one to 9 months after embolization, shrinkage of leiomyoma size was the most significant factor. One year after embolization, leiomyoma sizes decreased a little. Shrinkage of submucous leiomyoma was more significant than that of intratumoral one, and the latter was more significant than subserous one. Shrinkage of leiomyoma with large size ( volume ≥ 150cm~3) was less than that of small one. Menorrhagia, anemia and pressure symptoms were all resolved. There was no significant difference between pre- and post embolization ovarian hormone level. Conclusions The significant reduction in leiomyoma volume and resolution of clinical symptoms confirmed that the treatment validity of symptomatic leiomyomas by UAE. UAE is an effective therapeutic procedure which has no adverse effect on the ovarian function.

Objective To investigate the feasibility and safety of transabdominal perposterior mediastinum radical operation in the treatment of cardiac carcinoma. Methods Twenty-six cases of cardiac carcinoma invading low esophagus underwent transabdominal posterior mediastinum radical resection. Among them 9 patients received radical proximal gastroesophagectomy, and 17 cases did radical total gastroesophagectomy. Results The procedures were all successful. The mean operation time for total gastrectomy was (189±39) min, proximal subtotal gastrectomy was (153±35) min. The averge blood loss of total gastrectomy was (200±80) ml, proximal subtotal gastrectomy was (168±76) ml. The harvest of celiac lymph nodes were (23.3±7.3), esophageal lymph nodes were (4.1±2.0). Pneumonia was complicated in 4 cases and there was no anastomotic hemorrhage, leakage nor stenosis. All patients were followed up from 5 to 51 months, liver metastasis was found in 4 cases, lung metastasis in 2 patients and death in 1. There was no anastomotic stoma tumor recurrence. Conclusion It was feasible and safe to perform transabdominal perposterior mediastinum radical operation for cardiac carcinoma patients, provided that diaphragms was not involved and tumor invaded esophageal length was less than 5 cm.

AIM: To explore the possible changes in cell adhesion molecules and composition of complement activation in patients with acute myocardial infarction (AMI). METHODS: The expression of leukocyte CD18, soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular-cell adhesion molecule-1 (sVCAM-1) and composition of complement activation (sC5b-9) concentrations of patients with AMI (67 cases), old myocardial infarction (OMI, 42 cases) and 38 healthy volunteers were measured using enzyme-linked immunosorbent assay(ELISA). RESULTS: The expression of leukocyte CD18, sICAM-1,sVCAM -1 and sC5b-9 were significantly higher in AMI patients than that in normal controls and OMI patients(P

To explore the mechanism of protecting erythrocyte deformability (ED) of polysaccharide sulfate(PSS)and propyllene glycolmannurate sulfate(PGMS) in patients with acute myocardial infarction (AMI). The erythrocyte filtration index(EFI),erythrocgte membrane Na+,K+-ATPase .glutathione peroxidase(GSH-Px)activity and lipid peroxide(LPO) were measured in 52 patients with AMI. Meanwhile the effects of PSS and PGMS on EFI, Na+,K+-ATPase ,GSH-Px and LPO in AMI patients were observed in vitro. The results showed that the EFI and LPO were markedly higher ,Na+ ,K+-ATP ase and GSH-Px were si-hnificantly lower in patients than those in control(P0. 05). These results indicate that PSS and PGMS could improve the ED in patients ,and the efficacy of PSS or PGMS was related to enchancement of erythrocyte membrane ATP-ase anci GSH-Px activity.
