The Brachyury gene (T-gene) and its coded product Brachyury potein which belong to T-box transcription factor family,are critical in the development of mesoderm and formation of notochord.Recent researches show accumulating evidences of its important role in tumorigenesis and cancer progression.The mechanisms involved may include epithelial-mesenchymal transition,cancer stem cells,cell cycles,senescence and resistance of conventional radiotherapy or chemotherapy.

Aim: To prepare diclofenac sodium-layered double hydroxide nanohybrids(DS-LDH) and investigate its properties. Methods: The diclofenac sodium anions were hybridized with LDH by co-precipitation. The synthetic nanohybrids were characterized by various methods, such as laser particle sizer, XRD, IR, and TEM. Paddle method according to the Chinese Pharmacopoeia was used to determine the dissolution. The anti-inflammation of nanohybrids and diclofenac sodium were compared by the effect on auricular tumescence induced by xylene in mice. Results: The acidic negative ion of layered double hydroxides were replaced by the diclofenac anion to form DS-LDH. Release studies showed that the nanohybrids could serve as controlled release systems for DS. Zn-Al-NO3-LDH was proved to have character of neutral pH which is more suitable for orphthalmic preparation. The DS-LDH nanohybrids could keep the effect of anti-inflammation. Conclusion: Layered double hydroxide nanohybrids can be used as sustained-release carrier of anionic drugs. A novel type of drug-inorganic nanohybrids was prepared successfully which has a potential value of clinical application.

The incidence of adenocarcinoma of the esophagogastric junction ( AEG) is rising rapidly in recent years. AEG as an independent disease different from squamous cell carcinoma of the esophagus and gastric adenocarcinoma is getting acknowledged for most of scholars, with the distinctive anatomy location and involute recurrence and metastasis style. A higher rate of relapse and poor prognosis after resection become conscious since most of patients have been diagnosed with advanced disease, and adjuvant chemoradiotherapy needs to be valued further. But so far, there is no clinical data and subgroup analysis aimed at the value of postoperative treatment for AEG specially, leading to controversy is remaining in patients could get benefit from postoperative treatment, and delineation of the radiation target, etc. The design of the irradiation target should in terms of the clinical?pathological characteristics of the AEG, Siewert'''' s subtypes, the lymph node metastasis mapping and recurrence characteristics after surgery.

Objective To give an empirical study on the interests claims of employees in public hospitals. Methods By questionnaire investigation, to sum up data using factor analysis and pairedsamples T test, and to compare difference between different kinds of patients using ANOVA. Results The interests claims of employees can be summed up to seven factors and there is some significant difference between different kinds of employees. Conclusion At current stage, public hospitals need pay more attention to material interests claims of employees.

Objective:We aimed to explore the clinical features, computed tomography (CT) findings, treatment, and prognosis of bronchopulmonary carcinoid. Methods:Clinical data of 31 patients with primary carcinoid tumor of the lung were retrospectively re-viewed. The prognostic factors were analyzed via Cox univariate and multivariate analyses. Results: Clinical symptoms included coughing or expectoration in 17 of the 31 cases, hemoptysis or blood-stained sputum in 7 cases, and chest pains or shortness of breath in 8 cases. Six cases were asymptomatic. The CT scans showed round or oval nodules with clear boundaries, and enhancement CT scans indicated mild, homogeneous enhancement. Immunohistochemistry results revealed the positive expression rates of synaptophy-sin (Syn), chromogranin A (CgA), and neuron-specific enolase (NSE) were 90.3%(28/31), 87.1%(27/31), and 90.3%(28/31), respec-tively. Therapy and prognosis results were as follows:28 of the total number of patients underwent surgery, among which 3 underwent postoperative adjuvant therapy, 2 received chemotherapy; and only 1 refused treatment. The 1-year overall survival rates were 100%(18/18) and 92.3%(12/13), whereas the 3-year survival rates were 94.4%(17/18) and 69.2%(9/13) in the typical and atypical carcinoid cases, respectively. Cox univariate analysis results revealed that lymphatic metastasis (P=0.02), tissue types (P=0.017), TNM stage (P=0.005), and therapies (P=0.01) were the prognostic factors. Cox multivariate analysis results showed that lymphatic metastasis (P=0.032) and tissue types (P=0.002) were the independent prognostic factors. Conclusion:Compared with other lung cancers, the bron-chopulmonary lung carcinoid has no special clinical manifestation in clinical and radiographic images. The diagnosis was mainly based on histopathology results. Surgery was the main and effective treatment, whereas chemotherapy and radiotherapy showed unsatisfactory results. The overall prognosis was satisfactory. However, the atypical carcinoid was inferior to the typical carcinoid in terms of progno-sis. Pathological typing and lymph node metastasis were significant prognostic factors.

Objective To explore a new peptide-based approach independent of HLA to generate antigen-specific CD+ CD8+T cells. Methods Peripheral blood mononuclear cells(PBMC) were stimula- ted for 6 h with IE-1 peptide pool. Then the activated IFN-γsecreting ceils were tested by immunomagnetic selection. And the selected cells were cultured with radio-inactivated PBMC in medium with 100 IU/ml IL-2 for 4 weeks. Results The generated T cell lines consisted of IE-1 specific CD4+ T (6.88%) and CD8+ T cells 92.99%, which demonstrated antigen-specific killing and cytokine secretion. Conclusion T ceils can be proliferated with this new procedure, and maintain its phenotype and antigen-specific function.

OBJECTIVE:To provide references for the quality assessment of traditional Chinese liquid medicine-Fructus Polygoni Orientalis.METHODS:The description and the physicochemical identification of Fructus Polygoni Orientalis were carried out;the contents of the extractives were determined and the chemical composition of which was studied.The quality of commercial Fructus Polygoni Orientalis medicinal substances from15nationwide areas was investigated.RESULTS:The results showed that the content of the preparation was higher than that of the raw material in the water soluble extractive assaying;the content of the alcohol-soluble extractive was the opposite.Meletin was found to be contained in the Fructus Polygoni Orien?talis acetic ether extraction liquid by the TLC identification.There was only half maturing rate for most of the commercial Fructus Polygoni Orientalis.CONCLUSION:This method can be used as a reference for the quality assessment of Fructus Polygoni Orientalis.

Methods 45 patients after minimally invasive ventficulo-atrial shunt were given preoperative psychological care and preparations, postoperative observation of vital signs, con-sciousness, pupil, with or without intracranial hypertension, inadequate shunt or transitional symptoms, in-fectious symptoms, specific and basic care, awareness of postoperative complications and detailed guidance for discharge and follow-up jobs. Results Half month after shunt 28 cases regained consciousness, 9 cases with alleviated consciousness dysfunction, 8 cases with unchanged consciousness dysfunction, 5 cases with shunt blockage; 3 cases with over-shunt; 5 cases with inadequate shunt, 1 case with blood-borne in-fection, 1 case with shunt exposed, no intracranial infection, air embolism, complications such as endocardi-tis took place. Conclusions Adequate preoperative preparation and close postoperative observation, ef-fective specific care and basic care can increase success rate of ventriculo-atrial shunt and improve the quality of life of patients.
