A simple method of trypsin/collagenase I alternative digestion and iterative culture flask adherence to discard fibroblasts for bovine mammary cell culture was established in this study. By immunohistochemistry, flow cytometry, western blot, Electron microscopy analysis, the characteristics of bovine mammary cells were investigated in vitro. Effect of hyperthermia on the cell ultrastructures was also observed. The results showed that the mammary cells were diploid epithelia with intact 30 pairs chromatins, which could secrete alpha-casein into the medium. After exposed to hyperthermia, the cell condensed chromatin like crescent on the nuclei verges, mitochondria occurred expansion and vacuolization, and apoptotic bodies appeared, which suggested that heat stress could induce apoptosis of the mammary epithelia.

OBJECTIVETo evaluate the efficacy of Chinese medicine (CM) combined adjuvant chemotherapy in postponing relapse and metastasis of radical resected Ib-IIIa stage non-small cell lung cancer (NSCLC) patients, and to explore its effect in improving their quality of life (QOL) and clinical symptoms.
METHODSWe designed a cohort study of 336 radical resected Ib-IIIa NSCLC patients by analyzing disease free survival (DFS) using Log-rank test. They were randomly assigned to the control group (155 cases, treated by adjuvant chemotherapy group) and the test group (181 cases, treated by adjuvant chemotherapy combined CM). By using controlled method, 60 radical resected NSCLC patients undergoing NP/NC program in 2012 (vinorelbine 25 mg/m2, combined with cisplatin 75 mg/m2 on day 1 and day 8/on day 1 or on day 1, 2, and 3; or carboplatin AUC = 5 on day 1) were assigned to the control group (29 cases) and the test group (31 cases). QOL scores (using EORTC QLQ-LC43 questionnaire) and TCM symptoms scores were compared between the two groups before chemotherapy, peri-chemotherapy (one day before the 2nd course of chemotherapy) , and after chemotherapy (20 days after ending the 4th course of chemotherapy).
RESULTS(1) The median DFS was longer in the test group than in the control group, but with no statistical difference between the two groups (42.73 months vs 35.57 months , P = 0.179). In the subgroup analysis, there was statistical difference in IIIa stage DFS. The median IIIa stage DFS of was longer in the test group than in the control group with statistical difference (27.87 months vs 19. 93 months, P = 0.047). (2) In the control study, repeated measured data indicated there was significant difference in physical functions between the two groups (P < 0.05). Total scores for health states decreased more in the test group than in the control group, but with no statistical difference (P > 0.05). Scores for constipation and CM syndrome scores were higher in the test group than in the control group (P < 0.05).
CONCLUSIONSCM had advantages in postponing DFS of radical resected NSCLC patients, especially in IIIa stage. CM could improve their QOL and clinical symptoms during adjuvant chemotherapy.

OBJECTIVETo probe into a treatment method for increasing clinical therapeutic effect on xerophthalmia.
METHODSForty-five cases were randomly divided into acupuncture group 1, acupuncture group 2 and control group. The acupuncture group 1 were treated with acupuncture based on syndrome types, and the acupuncture group 2 with acupuncture at local acupoints, and the control group with dripping of artificial tears. Local symptoms of eyes, S1T, BUT and FL were observed before and after treatment.
RESULTSS1T and BUT increased after treatment in the two groups (P < 0.01, P < 0.05), but did not significantly change in the control group (P > 0.05). There were significant differences in change of FL as the control group compared with the acupuncture group 1 and 2. The total effective rate was 86.7%, 66.7% and 33.3% in the acupuncture group 1, 2 and the control group, respectively.
CONCLUSIONThe integral syndrome differentiation acupuncture can improve secretion of tear, increase stability of tear film, improve local symptoms of eyes with a therapeutic effect better than acupuncture at local acupoints and artificial tears.

BACKGROUNDTo study the relationship of Epstein-Barr virus (EBV) and T cell lymphoma.
METHODSSixty cases of T cell lymphomas were examined for the presence of EBV using in situ hybridization for EBV encoded RNA (EBERs).
RESULTSEBERs were detected in tumor cells in 37(69.8%) of 53 cases with peripheral T cell lymphoma, but in none of seven cases of precursor T lymphoblastic lymphoma. The total detected EBERs were 37(61.6%) in 60 cases of T cell lymphomas. By Revised European-American Lymphoma(REAL) classification, EBERs were detected in 2/2 angioimmuno-blastic T cell lymphoma,17/18 angiocentric lymphoma, 4/6 anaplastic large cell lymphoma and 14/27 peripheral T cell lymphoma, unspecified (51.9%). The frequency of EBERs among the extranodal peripheral T cell lymphoma was higher than the nodal (P less than 0.01) there was no significant correlation with the sex, age and clinical stage.
CONCLUSIONSThis study indicated that high incidence of EBV was observed in peripheral T cell lymphoma, with predilection for angiocentric lymphoma and extranodal presentation.

BACKGROUND: At present, finite element analysis can be used to judge intertrochanteric fractures, but mostly limited in the distribution of stress. Finite element model of various intertrochanteric fractures has not been reported in detail.OBJECTIVE: To build various types of intertrochanteric fracture models with Hypermesh 14.0 and LS-DYNA software to simulate the falling-induced external force on proximal femur, and to evaluate the effect of models, and to analyze the biomechanical mechanism of intertrochanteric fractures. METHODS: Normal side CT image data of one case of elderly intertrochanteric fracture were collected and imported into Mimics software to establish the proximal femur geometric models, were then analyzed and operated by LZ-DYNA solver after imported into Geomagic studio 2013 and Hypermesh 14.0 for smoothing and meshing. Before analysis, the material parameters were set, the boundary conditions were confirmed, and given the loading parameters. The operating results were checked in Hyper View. RESULTS AND CONCLUSION: (1) The distribution of stress of proximal femur exactly matched to the previous study. EvansⅠtype intertrochanteric fracture model was obtained under continuous shear stresses, and six types of fractures were obtained by adjusting the load. (2) These results manifest that based on the Hypermesh 14.0 and LS-DYNA software, the finite element can well simulate the intertrochanteric fractures, and shear stress plays an important role in intertrochanteric fractures, which can provide experimental basis for the prevention and treatment of intertrochanteric fractures.

OBJECTIVETo study the alteration of thymus matrix lymphocyte generator (TSLP) and change of the Th factor in the course of disease development, and to analyze the curative effect of inhalation of Vitamin A (VA) with corticosteroid for the treatment of asthmatic pneumonia.
METHODSAsthmatic pneumonia models were prepared by challenging rats with inhalation of ovalbumin for 4 weeks, and rested for 1 week. The treatment with VA and corticosteroid inhalation for 1 week was followed. The rat thymus and lung specimen were examen by histochemical and immunofluorescence staining.
RESULTSAfter 4 - 5 weeks of stimulation, there were more TSLP-positive cells and alveolar macrophages (AM) found in thymus and lung tissue of asthmatic group, the cell proliferation in spleen and thymus was obvious, and blood Th factors elevated. The inflammation within the lung tissue aggravated gradually. In VA group, the expression of TSLP and Th2 factors were all lowered at the 4th week. The TSLP expression slightly increased at the 5th week, and the cell proliferation within T-cell zone of spleen and thymus was strong at first and weakened later. Alveolar microphages (AM) increased significantly and the inflammation in the lung subsided gradually at the 5th week. In the hormone group, TSLP and Th2 factors expression in both thymus and lung were decreased at the 5th week, while the cell proliferation in thymus and lung was gradually increased. The quantity of AM was decreased, whereas the inflammation of the lung was increased gradually at the 5th week.
CONCLUSIONDuring asthmatic period elevated TSLP expression was accompanied by Th2 type responses while VA and corticosteroid both suppressed TSLP and Th2 factors expression. VA alone promoted T lymphocyte proliferation as well as the antigen elimination function by AM, after ceasing the usage, the lung inflammation abated gradually. In contrast, after ceasing the use of corticosteroid, inflammation aggravated.
