Journal of Central South University(Medical Sciences) 2009;34(2):148-151
ObjectiveTo determine the clinical effect and the prospect of cervical side-to-side stapled esophagogastric anastomosis. MethodsEighteen cases of upper and middle thoracic esophageal carcinoma were treated with esophagectomy and cervical side-to-side stapled esophagogastric anastomosis. The clinical data were collected and retrospectively analyzed. The average age of patients was 60.7 years and the ratio of male to female was 17∶1. The tumor included 4 upper part and 14 middle thoracic parts. The length of tumors was from 1 cm to 7 cm, with an average of 3.2 cm.ResultsThe post-operative TNM staging(AJCC) included 4 Stage Ⅱa,9 Stage Ⅱb,and 5 Stage Ⅲ. The operative incisions included 8 nontransthoracic cervical and abdominal double incisions, 9 right cervico-thoraco-abdominal triple incisions, and 1 left cervico-thoracic incision. One (5.56%) patient complicated with anastomotic leakage and was cured in 2 weeks by cervical drainage and absolute diet. All the 18 patients were followed up for 1 to 5 years,and no anastomotic stricture was found. Reflux esophagitis was found in 2 and the incidence rate was 11.11%.ConclusionCervical side-to-side esophagogastric anastomosis is a safe procedure with larger resection of margins and fewer complications. It is worth replicating.

AIM: To evaluate the effect of tissue factor on intravascular migration of tumor cells.METHODS: Expression of tissue factor in tumor cells (HT1080) was analyzed by flow cytometry and immunofluorescence staining. An in vitro model was used to observe intravascular migration of tumor cells. RESULTS: High expression of tissue factor was observed in tumor cells (HT1080). The antibody for tissue factor inhibited intravascular migration of tumor cells. CONCLUSION: Tissue factor stimulated tumor metastasis through promoting intravascular migration of tumor cells.

Objective To investigate the feasibility of using a new type carina type tracheal prosthesis made of complex material to replace trachea and carina defects. Methods According to biomechanics index, a new carina type tracheal prosthesis was designed and constituted with carbon fiber and silicon. 19 dogs were divided into two groups randomly: group A(n=11), the carina type tracheal prosthesis anastomosed directly to dog′s trachea and bronchus;group B(n=8), based on group A, meanwhile the diaphragm was incised and the pedicel caul was transplanted from abdominal cavity to thorax to enwrap the carina type tracheal prosthesis and anastomotic site. Results The average survival period post operation in group A and group B were (3.462?1.849)d and (6.475?1.062)d ,respectively. There was significant difference of the survival period between two groups(P

Marine medicine is an important part of Chinese medicine and a growth point of marine economy development.Exploration on the exact weight ratios and curative effect to expand marine medicine clinical application is a significant issue in marine medicine research at this stage. This paper presented a research supposition of“documents retrieval, extraction of marine medicine cases, establishment of case database, statistic analysis, data mining, herb pair Game Theory model establishment, herb pair usage under fixed dosage and matching, in order to explore a new idea of researching marine medicine combined with Game Theory. Through the literature retrieval and text extraction, 458 cases with the herb pair ofLong-Gu (LG) andMu-Li(ML) were received to establish the partnership game model. The iterative removals of strictly dominated strategies were adopted. Assuming that LG and ML used with an equal amount of 30 g was the best response, which reached the Nash equilibrium. The results suggested that dosages of LG and ML used equally at the amount of 30 g, 25 g, 24 g, 20 g, 18 g, 15 g were rationalizable strategies. Frequencies of using an equal amount of 30 g LG and ML was the most of mathematical statistics. LG and ML of 30 g were used equivalently to treat symptoms such as insomnia, inappetence, chills, tinnitus, physically and mentally fatigued, spontaneous sweating and night sweating, and so on with the effect of tranquilizing and constricting. The results can be validated and complemented among association rules analysis, mathematical statistics and game model. It implied that it was feasible to apply mathematical statistics and data mining in combination with Game Theory to study the marine medicine herb pair.

Objective:To explore effects of Idazoxan(IDA) on changes of neuroglial cells in spinal cords of rats with experimental autoimmune encephalomyelitis(EAE).Methods:Rat EAE was induced by immunization with spinal cord homogenates of Geania pigs.EAE clinical manifestations were assessed in terms of the scoring standards.Histological investigation and immunohistochemistry were observed for the inflammatory dedmylinative lesion of CNS and morphology of glial cells.Results:Ida could not decrease the incidence of EAE,but alleviate its clinical manifestation and histological changes.On day 15 after immunization,astrocytes in and around the inflammatory dedmylinative lesion of CNS in EAE rats treated with Ida increased in number and size,on the contrary,microglia decreased in number and size.Conclusion:Ida has protective effects on EAE and its functional mechanism may be concerned with modulation of immunological mechanism of CNS.

OBJECTIVE: To explore the association between low flow rate and reperfusion injury during the process of preserving liver by cold machine perfusing perfluorochemical oxygen carder solution. METHODS: Forty-four male adult Wister rats were randomly divided into normal, control, experimental Ⅰ and experimental Ⅱ groups. In the normal group, the removed liver was performed isolated reperfusion guided by Clavien method. In the other 3 groups, the removed liver was infused through the portal vein by the 4-5 ℃ conserved perfluorochemical oxygen carder solution. The infused rate was controlled at 0.4, 0.2, 0.1 mL/(min·g) with 18 hours perfusion, After that, isolated reperfusion was performed. The activity of aspartate aminotransferase, alanine transaminase and endotheiin mass concentration of the effluent was detected at minutes 10, 30, and 60 after reperfusion. The histopathological changes of liver under light and election microscopy were also observed. RESULTS: The activity of aspartate aminotransferase, alanine transaminase and endothelin mass concentration had no remarkable differences between the experimental Ⅰ group and control group (P > 0.05). The differences between the experimental Ⅱ group and control group were remarkable (P < 0.05). The light and electron microscopy showed that the histopathological changes of liver in the control and experimental Ⅰ groups was lightener than experimental Ⅱ group. CONCLUSION: During the process of preserving liver by cold machine perfusion, the rate of 0.1 ml/(min·g) perfluorochemical oxygen carder solution increase the injury of hepatocyte and sinusoidal endothelial cells, which eventually result in severity of reperfusion injury.

Objective To identify the biomarkers which can be used of estimating the biological behaviors of prostate cancer with osseous metastasis by SELDI-TOF-MS. Methods Screening for potential tumor biomarkers of serum samples from 19 prostate cancer patients and 35 prostate cancer patients with osseous metastasis by using the technology of SELDI-TOF-MS and CM 10 protein chips (Ciphergen Inc. USA).The PBS Ⅱ protein chip reader was used to analyze the CM10 protein chips and transform the protein information into the form of spectra. The protein contents of two groups in the same mass-to-charge ratio (M/Z value) were analyzed and preceded the analysis of variance by Biomarker Wizard software. The proteins whose contents in serum were significantly different, which was distinguished the correctly groups by Biomarker Pattern software. Results The contents of 4 proteins in the two groups were significantly different and the M/Z values of these 6 proteins were from 2000 to 20 000. The relative protein content of prostate cancer patients group was higher than that of Prostate Cancer patients with osseous metastasis group at the M/Z value of 2089,4281, 3507 and 4178 [(4.63±8.03) vs (9.88±10.77), (19.78±21.46) vs (26.73±19.41), (5.46±10.14) vs (8.10±8.74), (38.01 ±26.27) vs (45.25±20.40), (P<0.05)]. The relative protein content of prostate cancer patients group was lower than that of prostate cancer patients with osseous metastasis group at the M/Z value of 15 900 and 16 081 [(11.52±16.80) vs (4.84±5.83), (8.55±12.64) vs (3.56±3.90), (P<0.05)]. Conclusion The associated serum protein in prostate cancer with osseous metastasis can be quickly and exactly diagnosed by SELDI-TOF-MS with high sensitivity and specificity. This new method will be widely used in clinical application.
