New technologies and ideas are constantly emerging recently. With the arrival of the era of minimally invasive surgery, most of the colorectal cancer surgeries can be conducted through minimally invasive techniques. In this study, we discuss the status, characteristics, controversy, and consensus of minimally invasive techniques in colorectal cancer surgery.

ObjectiveThis paper discusses the instructional design of ＂General survey of medical culture＂,to provide the basis for the implementation of the teaching.MethodsThe first round of our teaching situation was concluded,to improve the teaching objectives,content,methods and the content and methods of teaching evaluation.Results The course is a new medical humanities curriculum to improve medical knowledge of the human spirit of nursing students,training the cultural literacy,but the teaching content should be combined with professional features,and teaching evaluation methods should be improved.ConclusionsRigorous designed curriculum,flexible and diverse teaching methods and forms of assessment and suggestions from the students are conducive to the improvement of the course.

Objective To summarize the main nursing point and experience of allogeneic small bowel transplantation.Methods One case underwent allogeneic small bowel transplantation in our hospital on the first of December 2010,the nursing measures were summarized.Results The patient passed the operation well-off,and survived the infection phase and repulsion phase in the transplantation ward.Conclusions Valid preoperative evaluation,taking active measures to prevent intraoperative hypothermia and infection,using self-made vacuum pads to prevent pressure sores during operation,are the guarantees for successful operation.

0.05).There was no significant variations of the parameters of newborns according to different levels of maternal serum ferritin. It has been shown that the iron status of mother does not affect the iron status of the infant. Fetus can draw enough iron to satisfy its need for growth and development, and this may cause iron deficiency in the mother. So, prophylaxis of iron deficiency during pregnancy is indicated.

The therapeutic trial of iron on 114 preschool children was studied. Before and after the trial, the iron status of the children was determined by measuring hemoglobin, free erythrocyte protoporphyrin, the ratio of free erythrocyte protoporphyrin/hemoglobin, serum iron, transferrin, transferria saturation, and serum ferritin. All of the children were given a two-month course of ferrous sulfate (4mg iron/kg/ day orally). The iron status of 4 years age group was superior to the 1-4 years group before the therapeutic trial. But after the trial, the iron status of these two groups was very significantly improved, all of the parameters of each group reached at the same levels. Those children with mean value of hemoglobin 3?g/g had good response. Of the 114 children 70 were iron deficient (61.4%), 83 had an increase in venous hemoglobin greater than 0.5g/dl after the trial (72.8%). Since the therapeutic trial is more economical and simpler so we favor to give the trial among the preschool children whose hemoglobin is below 12g/dl and/ or free erythrocyte protophyrin/hemoglobin ratio greater than 3?g/g, in order to avoid missing the iron-responsive individuals.

The induction of DNA single-strand breaks(ssb)by exposure to hematoporphyrin photosensitizer(PSD-007)followed by photoirradiation was observed in mice leukemia cells(L7712)in vitro. DNA ssb increased with the increase of dose of light in the rangeof 6.3-21 J/cm2 after treatment with 30?g/ml PSD-007. In lower concentration(1?g/ ml)of the drug,no ssb could be estimated after light exposure. Whan the concentration of PSD-007 was increased from 10 to 30?g/ml, however, the amount of ssb showed a rapid increase and tend to reach a plateau at 50ug/ml.comparing with ?-ray irradiation, we observed that PSD-007 could not increase the amount of ssb in cells irradiated with ?-ray and the most of ssb could be rejoined after incubation at 37℃ for 1 hour in the presence of PSD-007. However, DNA ssb induced by photosensitizer and light could not be repaired in post-photorad iated incubation. It is suggested that there exist some differences between the damages induced by photosensitization and by ioning radiation.From our experiment, we believe that DNA damage of cells is an early and critical event in photosensitization, which is different from that induced by y-ray irradiation.

3,= 4, the sensitivity and specificity in predicting response before iron administration were 77.4, 47.5; 71.7, 75.4; 52.8, 90.2; 18.9, 96.7 respectively. Both sensitivity and specificity were higher in two parameters combined, so that the two parameters combined to screen iron deficiency would be better. Because both sensitivity and specificity were higher in Hb and FEP/Hb, so we prefer Hb and FEP measurement for screening iron deficiency.

Objective To observe the effectiveness of naloxone treatment for acute alcohol toxicosis.Methods The effectiveness of naloxone treatment for 262 cases of acute alcohol toxicosis were compared with the effectiveness of routine treatment for 184 cases of the same toxicosis.Results The mean syptom subsidence time of medium degree toxicosis cases and the mean consciousness regaining time of serious degree toxicosis cases of naloxone treatment group were separately (05?02) hours and (98?21) hours(P

Objective To investigate the pathogen and inspection methods of the middle-aged women with constipation and evaluate the accuracy and clinical application of imaging to constipation.Methods First colonic transit test were used to 98 cases of middle-aged women who were diagnosed constipation by doctors,then air-barium double contrast examination were applied.Defecation radiography or simulation rectum defecography were used to those who were diagnosed as outlet obstruction.According to the measure target and diagnostic criteria of professor LU,the results were studied.Results 6 cases were abnormal within 8 cases who were inspected by barium enema.14cases were abnormal within 16 cases who were inspected by defecation radiography.Colonic transit test were used to 74 cases and only 6 cases were normal.16 cases were true slow transmission and 20 cases were false slow transmission.52 cases were outlet obstruction.20 volunteers were inspected by suspension barium sulfate and simulation rectum defecography.Conclusions Air-bariun double contrast examination could discover the organic disease and abnormal of rectum.colonic transit test,defecation radiography and simulation rectum defecography were simply and perfect methods to discover the pathogen of constipation.

Objective To investigate the role of survivin gene in the pathogenesis of endometriosis (EMs). Methods The expressions of survivin in endometriosis and normal endometrium tissue were determined ; the effects of GnRHa and COX-2 on the expression of survivin mRNA in endometriosis and normal endometrium in vitro and the effects of GnRHa and COX-2 on the apoptosis index in the cultured ectopie endometrial cells were investigated. Re-sults ①The expression of survivin mRNA was higher in patients with endometriosis than that of healthy controls (P <0.01) ,with no cyclical variation. ②GnBHa exerted a dose-dependent suppression of survivin mRNA expres-sion in cultured ectopic endometrioma cells as well as COX-2. The significant suppression was observed at the 100μg/L concentration of GnRHa and at the 40 μmol/L concentration of COX-2. No cooperation was found between them (P > 0.05). Conclusion ①The up-regulation of survivin mRNA expression may reduce the sensitivity of en-dometriotic cells to apeptosis. Elevated expression of survivin mRNA in ectopic endometrium may have important im-plications for the survival and proliferation of the ectopic endometrial tissue.②Both GnRHa and COX-2 can promote apoptosis by inhibiting survivin mRNA expression in ectopic endometrioma cells in vitro.
