Objective To acknowledge the effect of T-lymphocyte subset on lymph node micrometastasis in esophageal cancer patients by the study of the correlation between T-lymphocyte subset and micrometastasis.Methods CD3+、CD4+、CD8+and CD4+/CD8+ were examined in esophageal cancer patients under thoracotomy by flow cytometry,and the micrometastasis were examined by immunohistochemistry in lymph node that were diagnosed as negative for metastases by routine histopathological analysis.Two groups were divided by with or without micro-metastasis,T-lymphocyte subset were compared with two groups.Results CD3+,CD4+ and CD4+/CD8+were significantly lower in group with micrometastasis than in group without micrometastasis,CD8+ was significantly higher in group with micrometagtasis than in group without micrometastasis.Conclusion T-lymphocyte subset is closely associmed with micrometastasis and low CD3+,CD4+ and high CD8+ T-lymphocyte is associated with poor cancer-specific survival.

Objective In order to provide the reasons for local injecting Xiaozhiling to treat malignant tumors. Methods 10 mice were subcutaneosly injected with S 180 Tumor cell to create tumor models and then Xiaozhiling 10ml/kg were intratumorly injected for 3 times.Finally,observation and comparison were made for the pathologic changes under optic and electronic microscopies. Results The results showed that Xiaozhiling had strong antitumor effect on S 180 tumor(adquate rate was 37.3%).Pathalogical exemination revealed that the tumor tissue necrosed obviously,some wesslincataneous cells breaked up, red blood cells extravasation,micro blood clots formed.No changes occurred in the control group. Conclusions Xiaozhiling could be a new drug for clinical treatment of malignant tumor.

Objective: To observe the effect of Ruxiankang (RXK) Capsule (Radix Bupleuri, Poria, Rhizoma Atractylodis macrocephalae, Radix Angelicae Sinensis, Radix Paeoniae Alba, Rhizoma Cyperi, etc.) on mammary gland and sex hormone of rat with mastoplasia. Methods: After benzoate estradiol and progestogen were injected into rats for 30 days the mastoplasia model was made, the model rats were treated with tamoxifen and RXK Capsule for 30days, and injected estradiol at the same time. Results: RXK Capsule and tamoxifen could significantly inhibit HMG rat's mammary gland swell, reduce quantity of lobule alveolus in mammary glands and secretion ( P

Objective To investigate the impacts of γ-ray radiation on gene expressions of peripheral blood lymphocytes in SD rats,and to screen differential expression genes and biological pathways closely related to radiation injury.Methods The differential gene expression of peripheral blood lymphocytes in SD rats was selected by microarray at 6 h after 2 Gy 60Co γ-ray exposure in vitro and in vivo.Bioinformatics analysis of the differentially expressed genes was performed by using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases.Real-time quantitative PCR was applied to verify the screen results of the microarray.Results Fifty-five genes with three times over-expressed level were screened out from the radiation groups both in vitro and in vivo and they were involved in 6 signaling pathways.There were two differentially expressed genes of microarray assay were verified by PCR assay.Conclusions Differential expressed genes in the peripheral blood lymphocytes of SD rats could be induced by γ-ray radiation and they cooperatively contributed to a variety of biological processes.

ObjectiveTo summarize the experience of percutaneous nephrolithotomy under flexible ureteroscope in the treatment of staghorn calculi.Method The clinical data of 30 patieits with staghorn calculi undergoing percutaneous nephrolithotomy under flexible ureteroscope were reviewed for summarizing the surgical cooperation experience.Results All operations were successful,with the clearance rates of stage one and stage two calculi 86.0% and 95.0%,respectively.There occurred one case of massive hemorrhage,but no cases of kidney perforation,peritoneal perforation,liquid pneumothorax or organ damage.Conclusion Well-prepared surgical cooperation,full mastery of surgical procedures and skilled cooperation can increase surgical efficiency and safety by shortening surgical duration.

Literature of TCM contains abundant information of Chinese medicine. Traditional Chinese medicine information is characterized by its high degree of knowledge-intensive and complex inter-knowledge, so it is difficult to integrate and share knowledge. TheShanghanlun is one of the Chinese medical classics, and it includes the rules and methods of syndrome differentiation and treatment and it showed good effects in the clinical application. However, it is difficult to master for beginners. As a kind of knowledge organization tool, topic maps can flexibly define the relationship between knowledge, which realizes the visualization of knowledge network, and integrates and shares the distributed knowledge. This paper focused on the current situation of topic maps researches. The topic maps was used to organize the original content ofShanghanlun, construct the concept model of it and explore the specific application of topic maps technology in the field of traditional Chinese medicine.

OBJECTIVE:To improve hydroscopicity and fluidity of traditional Chinese drug extractum by spray drying and to improve affixes to the wall of the drier during drying for providing reasonable relative humidity of production.METHODS:The compounding of adjuvant and the technology were optimized by orthogonal experiment,and the hydroscopicity and fluidity of powdered extract were investigated.RESULTS:The hydroscopicity of traditional Chinese drug extractum can be greatly decreased by adding 3% gum arabic and 7% ?-CD.The optimum technological conditions were as follows:extractum density of 1.10g? mL-1,temperature of intake airflow of 170℃,atomization pressure of 0.5Mpa,and feed material speed of 400mL? h-1 by orthogonal experiment.The critical relative humidity of the optimum formula was 64%.CONCLUTION:The problems of time consuming and moisture absorption of traditional Chinese drug extractum existed in the traditional old technology can be improved in this new technology.

Objective To evaluate surgical therapy for recurrent rectovaginal fistula.Methods In this study.two patients were treated by endorectal advancement flap repair and one patient was treated by vascular pedicled segment of small bowel.Results All patients were cured and followed up from 4 to 20 months.During the period of follow-up there was no recurrence.Conclusions The procedures and timing of operation are important factors for a successful repair.Both the endorectal advancement flap and patch of intestine provide an effective methods in repairing recurrent rectovaginal fistula.
