To perfect the medical ethics archives,we should stress the filling system of medical ethics evaluation,the detailed check and registration of medical staff's medical ethics condition.It could form the right think leading and normative professional criterion of medical staff,developing their work potential and decrease the conflict between doctors and patients.The main purpose and significance to establish and perfect the medical ethics archives is that it could bring the guidance,self-discipline,awards and punishments and regulation role in the medical ethics construction.

The problems in nursing postgraduate training in China are summarized,which include the ambiguity of subject orientation,absence of unified standard on training objective,imperfection of tutor team,uncertainty of research direction,lack of scientific research funds,etc.The countermeasures are then proposed,and the direction of nursing postgraduate education reform in China is discussed.

Autophagy is a dynamic process which subcellular membranes undergo morphological changes that lead to the degradation of cellular cytoplasmic organelles and macromolecules.It is regulated by themammalian target of rapamycin ( mTOR ) -dependent or -independent signaling pathways.It has been demonstrated that autophagy is induced or inhibited in various tumor cells,and it is closely related with cell survival and drug resistance.Because of the complex relationships with cell death,the roles of autophagy in cancer developnent,treatment,and drug-resistance are not the same,and thus controlling autophagy properly may become one of new means of cancer therapy.

The BRAFV600E mutation in papillary thyroid carcinoma is the most common genetic event,which is an invasive tumor clinical phenotype and a poor prognosis indicator.The BRAFV600E mutation detection has an important guiding significance for the differential diagnosis of malignant thyroid nodules on preoperative,guiding the surgical resection range of thyroid cancer,judging the patient(s) prognosis and guiding the subsequent treatment of postoperative.

Based on analyzing the problems existed in hostital informatization, the paper proposes using shared-database to realize data sharing among various departments.It mainly introduces shared-database and its function module and customer display module. The introduction of shared-database is conducive to comprehensive management of hospital data, providing basis for future data mining.

Objective To investigate the role of PT H (1-34 ) on the expression of receptor activator factor of NF-κB ligand (RANKL) in the induction of osteoclasts and its effect to osteoclasts on compression side during the repairs of tooth root in rats model of tooth resorption by intermittent injection of small dose of PTH (1-34) .Methods After the model of tooth resorption was established in rats 6-8 weeks in age ,63 male SD rats were divided in three groups .Rats in the control group were not given injec-tions for any drugs ;The negative control group were given injections for normal saline 6μg/kg subcutaneously every other day ;The experimental group were given injections for PTH (1-34) 6 μg/kg(PTH :1 μg/mL) subcutaneously every other day ;then rats in every group were killed on the day 0 ,7 ,10 ,14 ,17 ,21 ,25 .TRAP staining for counting TRAP-positive stained osteoclasts ,calculat-ing the mean ;Ligand RANKL immunohistochemistry and using image-pro-plus image analysis system to measure the average opti-cal density value of compression side .Results On the day of discontinuation ,the tooth resorption continued in each group ;the num-ber of osteoclasts between every two arrays there were no significant statistic differences (P>0 .05);RANKL immunohistochemis-try :Compared with control group and the negative control group ,the experimental group significantly increased in early stage ,and reduced in latest stage(P<0 .05) .Conclusion It indicated that intermittent injection of small dose PTH (1-34) did not cease the rats tooth resorption which occured during the period of tooth repair .

Objective To discuss the value of double tunnel separation technique in the application of laparoscopic radical resection for rectal carcinoma. Methods A retrospective analysis of clinical data of 67 cases of laparoscopic radical resection for rectal carcinoma from September 2010 to July 2014 was made.There were 37 cases of Miles operation and 30 cases of Dixon operation, with laparoscopic double tunnel separation technique which refered to under the sigmoid colon mesentery space and under the mesorectum space. Results All cases of laparoscopic radical resection were completed.The duration of operation was 100-240 min, with an average of 158 min.The intraoperative blood loss was 50-200 ml, with an average of 110 ml.The hospitalization time was 8-15 d, with an average of 10 d.Complications included postoperative anastomotic leakage in 1 case, small intestinal obstruction induced by intestine pelvic adhesion in 1 case, and lower extremity deep venous thrombosis in 1 case, all of which were cured with conservative treatment. Conclusions Double tunnel separation technique in laparoscopic radical resection is helpful to application of total mesorectal excision, thus effectively protects blood vessels, nerves, and ureters.Meanwhile, the lymph nodes and extranodal tumor deposits can be cleaned to the greatest degree.

Objective To study the role of calcitonin-gene-related peptide (CGRP) and substance P (SP) in the pathogenesis of prurigo nodularis. Methods SABC immunohistochemical technique was used to examine the expression of CGRP and SP in lesional skin and uninvolved skin of 30 cases of prurigo nodularis and in skin of 15 normal controls. Results The strong expression of CGRP and SP was observed in the whole epidermis of lesional skin in 30 cases, with the expression surrounding cell membranes. The weak expression of CGRP and SP was observed in nonlesional and normal epidermis. CGRP and SP expression levels had significant differences in the lesional skin and in normal and uninvolved skin (P

Objective:Cardiac index(CI) and mixed venous oxygen saturation SvO2 were studied in 85 patients undergoing coronary artery bypass grafting(CABG). Methods: Measurement of CI and SvO2 was carried out with a fiberoptic ballon-tip thermodilation pulmonary artery catheter. Fentanyl-based anesthesia was applied in all patients. Hemodynamic parame-ters were obtained prior to anesthesia induction as the baseline, after endotracheal intubation, after stemotomy, after weaning of cardiopulmonary bypass, at 6 and 24h after operation. Results: CI and SvO2 increased or was not changed at all time intervals, compared with the baselines. The changes of SvO2 correlated well with those of CI. Conclusion: The results suggest that continuous monitoring of SvO2 may be useful to predicting alteration in CI in patients undergoing CABG.

Physical constraints is a commonly protective medical measure in clinic. if lack of humanistic nurs-ing in the use of the process,then it will give the patient a physical,psychological and ethic issues. This paper sum-marized the research status of humanistic nursing and physical constraints and concluded the humanistic nursing measures before, during, and after physical constraints, and thus to provide a reference for the further implementa-tion of humanistic nursing.
