The principal investigator responsibility system has been progressively under implementation at some of the domestic medical universities. However, since there are big differences between military medical universities and civilian ones in terms of organizational structures, tasks to be committed, functions and personnel systems, military medical universities have to consider own characteristics and well handle the following four pairs of relations in the process of implementing principal investigator responsibility system: the relation between the subject groups and the teaching and research sections, the relation between the subject research and the discipline construction, the relation between the subject research and the personnel training, and the relation between the collective assessment and the individual assessment in the process of performance assessment.

Objective To investigate the clinical application of nasal-insertion type ileus-tube in the treatment of adhesive small intestinal obstruction. Methods A total of 221 patients with simple adhesive small intestinal obstruction, who were admitted to authors’ hospital during the period from January 2010 to Aug. 2014, were enrolled in this study. The patients were randomly divided into nasal-insertion type ileus-tube group (n=111) and nasogastric tube group (n=110). After the procedure, the patients were kept under close observation, focusing on the abdominal distention, gastrointestinal decompression amount, the recovery time of anal exhaustion and defecation, the vanishing time of intestinal air-liquid plane on erect abdominal X-ray film, etc. The cure rate, effective rate and transit-operation rate were calculated. The results were compared between the two groups. Results The tube placement operation was successfully performed in all patients. Compared with the nasogastric tube group, in the nasal-insertion type ileus-tube group the recovery time of abdominal distention, anal exhaustion and defecation and the vanishing time of intestinal air-liquid plane on erect abdominal X-ray film were obviously shorter, and the gastrointestinal decompression amount was larger. In the nasal-insertion type ileus-tube group the cure rate and effective rate were significantly increased, while the transit-operation rate was decreased; the differences between the two groups were statistically significant (P<0.05). Conclusion For the treatment of adhesive small intestinal obstruction, the placement of nasal-insertion type ileus-tube is effective and reliable. This technique can strikingly improve the clinical symptoms, therefore, it is worthy of promotion and application in clinical practice.

Objective:
To determine the hemoglobin level and blood pressure and the factors that influence their recovery in relocated workers who were unfit for duties at high altitude.
Methods:
The physical examination data of 693 relocated workers who previously worked at high altitude were dynamically monitored from January 2006 to June 2015 in order to examine the recovery of hemoglobin level and blood pressure.
Results:
The rate of hemoglobin recovery was 81.37% among the 161 relocated workers with abnormal hemoglobin levels, and the rate of blood pressure recovery was 69.51% among the 164 relocated workers with abnormal blood pressure. The rates of hemoglobin and blood pressure recovery were decreased in individuals aged 40 years and older. The peak recovery time of hemoglobin was 11-15 months following relocation, and that of blood pressure was 5-7 months and 11-13 months following relocation. The half-year blood pressure recovery rate and 2-year hemoglobin recovery rate following relocation were significantly higher in workers who worked at 2500-3000 m altitude than in those at ≥3000 m (
