International cooperation and exchanges plays an important role in the disciplines development in hospital,and can indirectly improve the overall capacity and quality of healthcare..This paper draw on 10 years of international cooperation and exchange in the practice of discipline development,,analyzed working patterns and mechanisms to strengthen international scientific cooperation.

The presence of hepatitis B virus (HBV) proteins leads to changes in the cellular gene expression. As a consequence, the cellular signaling processes are influenced by the actions of HBV proteins. It has been shown that HBV nucleocapsid protein and the amino-terminal part of polymerase termed as terminal protein (TP) could inhibit interferon signaling. Further, the global gene expression profiles differ in hepatoma cells with and without HBV gene expression and replication. The expression of interferon (IFN) stimulated genes (ISGs) was differently regulated in cells with HBV replication and could be modulated by antiviral treatments. The HBV TP has been found to modulate the ISG expression and enhance the HBV replication. The modulation of the cellular signaling processes by HBV may have significant implications for pathogenesis.

Objective: To explore the association of the serum levels of cytokine IL-10 with the occurrence of cachexia from patients with low-third gastric cancer. Methods: Radioimmunoassay was used to examine the serum levels of IL-10 in 150 patients with low-third gastric cancer and 135 healthy controls. Results: The serum levels of IL-10 were significantly higher in patients with low-third gastric cancer than controls(Z=-11.862, P<0.01). The serum levels of IL-10 were significantly higher in patients with low-third gastric cancer of clinical stageⅢ/Ⅳ than those with clinical stageⅠ/Ⅱ(Z=-10.028, P<0.01). The serum levels of IL-10 were significantly higher in patients with cachexia than those without(Z=-10.369, P<0.01). Logistic regression analysis showed that IL-10 was associated with odds ratios of 1.599 (95%CI:1.299-1.870, P<0.01) for cachexia. Conclusion: The serum levels of IL-10 are possibly associated with the occurrence of cachexia from patients with low-third gastric cancer.

Purpose To investigate the clinical pathological features, histologic features, and prognosis of solid papillary carcinoma ( SPC) of breast. Methods Nine cases of SPC of breast were analyzed by morphological observation, AB-PAS staining and immuno-histochemical MaxVision staining. The follow-up and analysis of the clinical datas of these nine cases were performed and relevant liter-atures were also reviewed. Results The age of 9 cases of SPC of breast ranged from 32 to 83 years old (mean age is 69. 2 years old). Three cases presented with nipple discharge. Nuclear levels of 9 cases were between low to mid-level. Seven cases were associated with intracellular and extracellular mucus secretion, two cases with calcification, and 3 cases with comedonecrosis. All of these nine cases were ER, PR positive and the positive rates were high ( >70%) , HER-2 was all negative. Syn expression in these nine cases were diffused positive except for one case showing focal positive, 4 with CgA diffused positive, 1 with partial positive and 4 were negative of CgA. Six patients had partial loss of the expression of myoepithelial markers, and 3 cases with complete myoepithelial expression. Ki-67 proliferation index was between 3% and 20%. Except for only one case with small area of invasive ductal carcinoma (IDC) (2 mm in great diameter) , all other cases were not associated with other types of breast cancer, sentinel lymph nodes and/or axillary/supracla-vicular lymph nodes metastasis. 8 patients accepted breast-conserving surgey, one case did not undergo radical mastectomy for small le-sion. All of these cases were accepted further endocrine drugs treatment and only one case accepted chemical therapy simultaneously because of the accompanied IDC. None of them was found to relapse for 3 to 61 months (mean 19. 6 months) of follow-up. Conclusion Nine cases of SPC of breast showed some characteristics such as relatively low nuclear level, often accompanied by intracellular and extracellular mucus secretion, positive for neuroendocrine marker, low lymph node metastasis rate, and no recurrence, which suggest that SPC may have a better clinical prognosis.

The medical consulting service, disease inquiry and seeking medical advice functions of 10 commonly available APP software in China for seeking medical advice, such asRapid Asking Doctors,Handholding Doc-tor Selection, andChunyu Handholding Doctors, were compared, which showed that although the functions of APP software in China for seeking medical advice could meet the requirement of people for seeking medical advice, importance should be further attached to their accurate and integrative information and establishment of profit-making model in order to promote the sustainable development of medical APP software.

Objective To introduce Checklist Individual Strength(CIS)into China,and evaluate its reliability and validity.Methods CIS was translated into Chinese language and the reverse translation was done by several experts.Validity and reliability were implemented in 214 cases with cerebral infarction.Results 4 components were extracted in factor analysis,and the total cumulative contribution was 78.984%.By correlation analysis,the twenty items were divided into 4 domains:subjective feeling of fatigue,concentration,motivation and physical activity,it was same as in the English version.Cronbach α of four domains were 0.9256,0.9072,0.7598,and 0.9157,respectively.Conclusion Psychometric properties(reliabilities and validities)of CIS Chinese version is met with satisfaction and seems to be adaptable to Chinese cerebral infarction patients.

Objective To analyze the instruments for post stroke fatigue, Fatigue Severity Scale (FSS)，Checklist Individual Strength (CIS) and Fatigue Impact Scale (FIS). Methods The FSS，CIS and FIS were applied in 214 cases with cerebral infarction. They were combined together at the (sub)scale level, and evaluated with Mokken Scale Analysis for Polytomous Items, for validity and reliability. Results and Conclusion Three scales were and The combined scale proved to be acceptable (H>0.5). 3 components were extracted in factor analysis, and the their total cumulative contribution was 77.504%, with reliability (α) of 0.8097，0.7094 and 0.8019 respectively. FSS put emphasis on the fatigue experiences of stroke patients, CIS on the influence of fatigue on, and FIS on the social function.

Purpose To describe clinicopathological features, diagnosis and differential diagnosis of Castleman′s disease. Methods Retrospective analyses of the clinical data, clinicopathology and immunohistochemistry were conducted in ten cases of Castleman dis-ease and reviewed of literature. Results There were 8 cases of unicenrtic Castleman′s disease and 2 cases of multicentric Castleman′s disease. Pathologically, there were 6 cases of hayline vascular types, one case of plasmatcyic type and 3 cases of mixed type in all Castleman′s disease. Immunohistochemically, all cases were negative for BCL-6 and CD10, and Ki-67 expression was less than or e-qual to 30%. There were 4 cases with complete follow-up data, including one case of intermediate type, 3 cases of hyaline vascular type which were healed by surgical resection without recurrence. Conclusions Castleman′s disease is a rare and lymphoproliferative disorders with unknown cause, it is not easy to diagnose before the operation. Whether immunohistochemical features reflect abnormal immune function or play unknown role in the pathogenesis of Castleman′s disease is also demanded further study.

Cervical anastomosis by the thoracic approach for the treatment of upper esophageal cancer can simplify surgical steps and reduce incidence of anastomotic leak. This approach has been used for 26 patients with upper esophageal cancer who were admitted to the Jiangsu Cancer Hospital from July 2006 to August 2009. The mean length between lesion and incisor was 23.3 cm. General anesthesia and double-lumen intubation through left posterolateral incision in the fifth intercostal space was adopted. The stomach was dissociated with the technique of "in situ dissociation", and esophagus was dissociated conventionally. Double purse-string suture was adopted to fix the esophageal mucosa onto the supportive base of the stapler, and make purse-string suture to fix stomach on the center pole of the stapler. There was one failure case which has been converted to the manual cervical anastomosis, and the operations for the rest 25 cases were completed successfully, without anastomotic leakage and positive margin. The average blood loss was (352 ±211 )ml, and the average operation time was (3.7 ±0.6 )hours.
