In order to establish more simple and effective rat orthotopic lung transplantation models, 20 rats were divided into donor and recipient groups. Rat lung transplantation models were established by using improved cuff technique. All the 10 operations were accomplished successfully. The mean operative time of recipients was 45 +/- 4 min. The survival time was over 30 days after lung transplantation. The checks of X-ray were almost normal. There was no significant difference in the blood gas analysis before and after clipping the right hilum (P > .05). This method is more simple, applicable and requires less time.

This article reviewed characteristics of geriatric traumatic spinal cord injury, including incidence, causes and clinical features, as well as definition, differenciation, special management and treatment strategy for geriatric traumatic spine and spinal cord injury.

ObjectiveTo investigate the characteristics of patients with flaccid paralysis after high spinal cord injury. Methods1014 cases with traumatic spinal cord injury were investigated. The patients with flaccid paralysis after high spinal cord injury (spinal fractures above the level of T10) were analyzed. Results6 patients were ananlyzed, including 5 males and 1 female, mean of age was (42±12). The neurological injury involved C7 to T8, and the fractures involved T3 to T10. 3 cases had the neurological deterioration upward at least 3 spinal segments after operation compared with the fractures. One case accomplicated with severe pain in the chest had the subacute progressive ascending myelopathy up to C7 level. MRI showed extensive atrophy of thoracic spinal cord 6 months later in 5 cases. ConclusionThe incidence of flaccid paralysis after high spinal cord injury was rare. It presents the extensive thoracic spinal cord atrophy, and the causes and mechanisms are not clear.

BACKGROUND: The expression of Fas antigen and P53 protein in colorectal cancer could reflect the biological character and the prognosis of the tumor.OBJECTIVE: To investigate the relationship between the expression of Fas antigen and P53 protein in coloreetal cancer and the tumor-related biological characters.DESIGN: A controlled experiment by introducing pathological specimens as subjects.SETTING: The study was conducted in the Department of Pathology of Xijing Hospital Affiliated with the Fourth Military Medical University of Chinese PLA.PARTICIPANT S: Totally 32 pathological specimens of colorectal cancer were randomly selected from the Department of Surgery of Xijing Hospital between January 1995 and October 1998. Sixteen normal large intestine tissues were selected form the cadaver of pathology department.METHODS: The expression of Fas antigen and P53 protein in 32 colorectal cancer tissue and 16 normal intestine tissue were tested and compared with immunohistochemical method.MAIN OUTCOME MEASURES: Fas antigen and P53 protein expression in coloreetal cancer and normal intestine, and the clinical indicators of patients with colorectal cancer.RESULTS: The expression of Fas antigen was positive in normal large intestine tissue while the expression of P53 protein was negative. The positive rate of Fas antigen expression in colorectal cancer was 41% (13/32), while the positive rate of P53 expression in colorectal caner was 53% (17/32). Fas antigen significantly decreased in colorectal cancer tissues. The expression of Fas antigen was correlated with the histological type of colorectal cancer and its liver metastasis( P ＜ 0.05) . And the expression of P53 protein was correlated with the liver metastasis of colorectal cancer( P ＜ 0. 05).CONCLUSION: The expression of Fas antigen significantly decreases in colorectal cancer. The higher the malignance is, the more significant less the expression is. Fas antigen does not express in liver metastasis patients. P53protein had positive expression in colorectal cancer tissues, especially in patients with liver metastasis. The reduction and deletion of Fas antigen expression and the excessive expression of P53 protein indicate poor prognosis.

OBJECTIVE:To observe the efficacy and safety of spraying mannatide and 5-fluorouracil in anocelia during sur-gery of lung cancer based on the adjuvant chemotherapy. METHODS:Totally 114 patients with lung cancer radical surgery were randomly divided into observation group(59 cases)and control group(55 cases). There were spraying mannatide(40-80 mg)and 5-fluorouracil(500 mg)in the observation group;and nothing drugs were sprayed in control group. The patients higher than phaseⅡ were treated by adjuvant chemotherapy after surgery for continuous 2 cycles,21 d as a cycle. The clinical data was compared, including amount of bleeding and drainage,hospital stay,complications,toxicity,KPS score,body weight changes,immune func-tion,survival rate and recurrence rates between 2 groups. RESULTS:There were no significant differences among the amount of bleeding and drainage,hospital stay and complications in the 2 groups (P>0.05). The nausea,vomiting,leucopenia,the KPS score,improvement of total effective rate,and improvement rate of body mass,immune function,survival rate in 1 and 2 year (s),recurrence rate and time within 2 years in observation group were significantly better than control group,with significant dif-ferences(P<0.01 or P<0.05). CONCLUSIONS:Spraying mannatide and 5-fluorouracil can reduce the toxicity in anocelia during surgery of lung cancer based on the adjuvant chemotherapy,improve the immune function and survival rate,reduce recurrence rate and prolong the recurrence time.

The incidence of venous thromboembolism after spinal cord injury is high, and its diagnosis and prevention received much attention in clinical research in recent years. Because of the special characteristics, the prevention of venous thrombosis should be combined with basic prevention, physical prevention and drug prevention. According to the different situations of venous thromboembolism in patients with spinal cord injury, the prevention methods need to adjust to carry out multidisciplinary comprehensive treatment.

The management system of work attendance is developed by the support of local area network of No.1 Military Medical Project and by the use of PowerBuilder. The system is applied to record work attendance on net, by which the management department can check work attendance of all departments of our hospital at any time. The application of the system realizes the management of work attendance on network, enhances work efficiency and avoids trivial manual work of count and collection.

Objective To study the effects of breast conserving surgery for early stage breast cancer. Methods The record of 38 patients with 0-IIa-stage breast cancer who received breast conserving surgery from Jan. 2005 to Feb.2010 was reviewed. The short-term effect was analyzed and the cosmetic effect was evaluated according to Rose standard. Results All patients recovered well and they were all satisfied with the shape of their breasts. No complication occurred. During the follow-up, no local recurrence and distant metastasis occurred. Conclusion Satisfactory clinical and cosmetic effect can be achieved by breast-conserving surgery in patients with early stage breast cancer.

The outcome of spinal cord injury is related to many factors, such as mechanism and severity of injury, and differences of individual. The standard of clinical trial plays a very important role in the reliability of the research. especially the inclusion and exclusion criterias, ethical issues, treatment standardization, informed consent and other issues. The effect of these factors on the clinical trial of spinal cord injury was summarized in this article. The inclusion and exclusion criterias to control the consistency should be developed based on the specific research content. Informed consent for clinical trial is also necessary, especially to the clinical trials with uncertainly benefits and risks, as well as the standardization of the operation procedures and rehabilitation treatment.

Objective To assess the value of emergency interventional embolization in treating traumatic spleen rupture. Methods A total of 74 patients with traumatic spleen rupture, who were encountered at authors’ hospital during the period from July 2007 to July 2013, were enrolled in this study. The clinical data were retrospectively analyzed. The patients were divided into embolization group (n = 38) and surgery group (n = 36). Interventional splenic artery embolization was carried out in the patients of the embolization group, and surgical repair was employed in the patients of the surgery group. The operation time, the amount of blood loss during the procedure, the hospitalization days, the preservation rate of the spleen and the occurrence of procedure- related adverse events were recorded, and the results were compared between the two groups. Results No significant difference in the operation time existed between the two groups (P = 0.061). The amount of blood loss during the procedure, the hospitalization days and the occurrence of procedure- related adverse events in the embolization group were significantly lower than those in the surgery group (P < 0.05), while the preservation rate of the spleen of the embolization group was significantly higher than that of the surgery group (P = 0.026). Conclusion Emergency interventional embolization is a safe procedure for the treatment of traumatic spleen rupture, this technique can improve the preservation rate of the spleen when compared with traditional surgical repair treatment.
