Nowadays the education of medical professional ethics has been obviously weakened.We can see that from some mainly expressions: There are many prejudices about medical ethics and the medical ethics education seems not very effective.But the medical professional ethics education is an important part of medical education,which directly affects the healthy development of medical and hygienic enterprise.And we must correct it,enhance it.We should inherit the good quarters of traditional medical ethics,reestablish the humanism medicine,promote virtue of medical personnel increasing,and establish the professional ethics of medical students before they become doctors.

Objective To study the method, advantage and shortcoming of mini-laparoscopic treatment for indirect inguinal hemia in children. Methods 136 cases with indirect inguinal hernia(right:75cases,left:44 cases,bilateral:17 cases) had been treated by high ligation with mini-laparoscopy. Results The mean operation time was 10 mmin for unilateral hernia and 23 mmin for bilateral hernia. Among 119 cases with unilateral hernia,38 cases had been found with contralateral latent hernia. The mean of postoperative inhospital stay were about 1 ～ 2 day(s). All patients had been followed-up for 3 ～ 12 months,there were only 2 cases recurrence found but no complications was detected.Conclusion Mini-laparoscopic high ligation for indirect inguinal hernia in children is a single, safe, satisfactory, effective,and minimally invasive surgical method.

Objective The aim of this paper was to develop the Mobile Nutrition Order System based on the technology of hospital information system to adapt the nutrition and food security management model in the new situation, so that the unified informa-tization management of diet for patients could be implemented by the Department of Nutrition. Methods The Mobile Nutrition Order System, with the functions of information entry, nutrition recipe, order making and data transmission, could be constructed by the com-bination of technologies between informatization and digital order. Results The automation of nutrition order in hospital was a-chieved, and the nutrition recipe and nutritional therapy could be realized in hospital, the effect was very obvious. Conclusion Since the application of Mobile Nutrition Order System, the labor intensity of servers has been reduced, saving working hours effective-ly.Meanwhile, the management of nutritional therapy was improved and the quality of logistics services in hospital and nutritional ther-apy ascend to a new high.

Objective To explore the application of mini-laparoscopy in the diagnosis and management of nonpalpable undescended testis in children.Methods 38 cases of impalpabal testes(46 testicular) had been operated by mini-laparoscopy in children with cryptorchidism.Results 38 children with nonpalpable undescended testis (46 testicular) had been operated by mini-laparoscope.Results After laparoscopic exploration,inguinal probe and postoperative pathology,it had been confirmed that 2 testicular were absent,34 testicular were found in high inguinal location,10 testicular were located in intraperitoneal cavity.In addition to the absent testicular,the rest had been performed with mini-laparoscope:one period descent fixation 41 testes,Fowler-Stephens (F-S) installment orchiopexy three testes.Follow-up with side testicular atrophy 2,including one period orchiopexy a testis,F-S installment fixation a testicular; Testicular rebound 1,who had been operated with one phase of testicular descent fixtion.Conclusion For inguinal failed to find the testicular,children with cryptorchidism should be done by laparoscopy because of its positioning accuracy,and most children can do a period drop fixed,but for those really intraperitoneal more exalted person,stage surgery should be needed.Its overall treatment effect is satisfactory and is worth popularizing.

Objective To establish reverse transcriptase-polymerase chain reaction(RT-PCR) with primers specific for CEA gene and CK20 gene to detect circulating tumor cells in peripheral blood of esophageal cancer pa-tients,and try to find the relationship between the mRNA expression and micrometastasis. Methods The expressions of CEA,CK20 were analyzed by RT-PCR in 53 cases of esophageal tumor tissue and in peripheral blood,compared with 10 patients with benign esophageal disease and 20 healthy volunteers. Results The expressions of CEA-mRNA, CK20-mRNA were 96.23% (51/53), 100% ( 53/53 ) in 53 esophageal tumor tissue and were 52.83% (28/53), 49.06% (26/53) in peripheral blood of 53 esophageal cancer patients. In control group,there was only one expression of CEA-mRNA in peripheral blood of 10 patients with benign esophageal disease,as well as in 20 healthy volunteers. There was no expression of CK20-mRNA in peripheral blood of 10 patients with benign esophageal disease and 20 healthy volunteers. Conclusion CEA-mRNA, CK20-mRNA might be specific and sensitive markers to detect circu-lating tumor cells in peripheral blood and their expression was closely related to TNM stages of the esophageal cancer patients.
