Objective To investigate the feasibility of establishing tumor model of MDR in rabbit liver with VX2 tumor induced by adriamycin. Methods 20 white rabbits were randomly divided into 4 groups with 5 for each. Liver tumor was established with VX2 tissue together with or without MDR-induced for their formations. VX2 tumor without MDR-induced was included in group A and B ,while MDR-induced tumor was employed in groupe C and D. Contrast enhanced CT was performed three weeks later to assess the volume of tumors. 4 mg adriamycin (dilute with 2ml of saline) was infused in group A and C via the common herpatic artery directly and respectirely; whereas same amount of saline adminisfrated through the same way for group B and D. Follow up CT was performed one week later to assess the change of tumor. Apoptosis rate was analized for each group by means of flow cytometry (FCM). Results No significant difference was found between the 4 groups three weeks after the establishment in term of tumor volume. Follow up CT performed 1 week after the treatment showed the volume increase of tumor for all groups. Group A was significantly lower than the other three groups in tumor growth rate (P0.05). The apoptosis rate of group A detected by FCM was significantly higher than the other three groups(P0.05). Conclusion Implanted liver tumor with VX2 induced by, adriamycin in tumor carrying rabbits possesses the character of drug resistance, which is profitable to be a liver tumor model of MDR for the therapeutic trial.

Objective: To explore the relationship between prevalence of atrial fibrillation (AF), iskhemia stoke and CHA2DS2-VASc score in patients≥65 years in order to provide prevention and treatment basis in clinical practice. Methods: A total of 5016 patients admitted in our hospital from 2013-10 to 2015-10 were enrolled. The patients were divided into 2 groups: AF group, n=437 and Non-AF patients, n=4579; according to age, the patients were further assigned into 4 subgroups as <65 years subgroup, (65-74) years subgroup, (75-84) years subgroup and ≥85 years subgroup. The risk factors for AF occurrence were retrospectively studied. Results: Compared with the Non-AF group, the patients in AF group had the elder age and more male gender, both P<0.001; more patients combining with hypertension, coronary artery disease (CAD), diabetes, sick sinus syndrome and rheumatic heart disease, all P<0.001. Age, male gender, CAD, sick sinus syndrome and rheumatic heart disease were the independent risk factors for AF occurrence. Compared with Non-AF group, AF group showed the higher prevalence rate of ischemic stroke and the elder onset age, both P<0.01. For non-valvular AF, the ratio of patients with CHA2DS2-VASc score≥2 was higher than those with CHA2DS2-VASc score<2 and the rate of anticoagulant therapy was decreasing by age increasing, all P<0.001. Conclusion: Age, male gender, CAD, sick sinus syndrome and rheumatic heart disease were independently related to AF occurrence. Non-valvular AF patients had the higher risk for ischemic stroke than non-AF patients, anticoagulation therapy should be conducted at the early stage.

Objective To explore the effect of Jiangzhipailuan decoction in regulating PPARα( belong to the nuclear receptor family of ligand-activated transcription factors ), PGC- 1α ( peroxime proliferator activated releptour)and SREBP-1c( belong to the baichelix-loop-helix-leucine zipper class of transcription factors), SCAP( SREBP cleavage activating protein) related to lipid metabolism in the treatment of polycystic ovarian syndrome. Methods 84 patients suffered polycystic ovary syndrome were randomly divided into 4 groups: one received traditional Chinese medicine treatment, one western medicine treatment, one combination therapy and one as the control group. Traditional Chinese medicine group was treated with Jiangzhipailuan decoction treatment for 3 months, western medicine group was treated with up to Diane-35 ( ethinyl cyproterone tablets) for three cycles, while the combination therapy group was treated with traditional Chinese medicine ,western medicine as well as combined treatment for 3 courses. Results In the combination therapy group the PPARα, PGC-1α and decreased SREBP-1c, SCAP copy number was significantly improved ,and body mass index was significantly lowered. The total improvement rate of menstrual in three groups were 71.42% ,75.00% ,92.86% respectively. Conclusion Jiangzhipailuan decoction played a prominent role in regulating PPARα,PGC-1α and SREBP-1c,SCAP related to lipid metabolism in the treatment of polycystic ovarian syndrome.

The expressions of estrogen receptor (ER) α,ERβ1,and ERβ2 in thyroid carcinoma,thyroid adenoma,and adjacent normal thyroid tissue were determined by RT-PCR and immunohistochemistry,and the relationship of expression levels of three ERs and the main clinical pathologic parameters were evaluated.The result showed that ERα mRNA expression in papillary thyroid carcinoma(PTC) tissues was significantly higher than adjacent normal tissue,while,ERβ2 mRNA expression in PTC tissues was significantly lower than normal tissue ( P＜0.05 ).The positive expression of ERβ1 and ERβ2 in the thyroid carcinoma was related with the histological variant of carcinomas; the ERβ2 expressions were related with the lymph node metastasis and TNM staging of the carcinomas.These results suggest that the decreased ERβ2 expression may induce proliferation and carcinogenesis of thyroid follicular epithelial cells as well as progression of the carcinoma,and is a powerful prognostic indicator.

Objective To investigate the expression of NF-κBp65 in hippocampus after the XST intervention therapy in the SD rats with global cerebral I/R injury and testify the protective effect of XST after global cerebral I/R injury.Methods 72 healthy SD rats were randomly divided into 3 groups,sham operation(SO) group ( n =24),I/R group( n =24) and XST group( n =24).The model of acute global cerebral ischemia/reperfusion (including:I/R and XST group) injury was produced by means of simple Pulsinelli- brierley's four arteries occlusion method.H.E.staining was performed to detect the number of surviving neurons and TUNEL was used to detect the rate of neurons apoptosis.The expression activation of NF-κB p65 in hippocampus comu-ammonis ( CA1 ) region were examined by immunohistochemical method (SABC).Results The survival pyramidal neurons in the XST group continued to increase,and it was significantly more than the I/R group at each time-point after reperfusion[ (99.23 ±4.22)/mm vs (75.83 ±7.17 )/mm,(80.93 ± 5.36)/mm vs (51.50 ± 8.26 )/mm,(103.24 ± 5.48 )/mm vs (35.67 ± 13.17 )/mm,( 126.22 ± 7.54 )/mm vs (9.83 ± 4.71 )/mm ],the differences were statistically significant ( P ＜0.01 ).The apoptosis rate of pyramidal cell in the XST group at each time-point were more significantly reduced than the I/R group [ ( 8.82 ± 2.71 ) ％ vs ( 22.58 ± 4.68 ) ％.( 19.15 ± 6.23 ) ％ vs (42.68 ± 3.04 ) ％,( 11.82 ± 2.87 ) ％ vs ( 55.51 ± 6.81 ) ％,( 8.44 ± 3.23 ) ％ vs ( 71.69 ± 7.71 ) ％ ],the differences were statistically significant ( P ＜0.01 ).The positive neurons of NF-κBp65 expression in the XST group at different time-points were significantly less than the L/R group[ ( 13.20 ±2.50) vs ( 18.00 ± 1.87),(8.20 ±5.31) vs (41.60±3.65),(6.70±3.36) vs (55.30±5.10),(7.10±3.57) vs (72.80 ±4.71)],the differences were statistically significant ( P ＜ 0.05,P ＜ 0.01 ).Conclusions After global cerebral ischemia/reperfusion,XST could protect the brain from global cerebral ischemia/reperfusion injury by holding up the expression of NF- kappaB p65,and inhibiting neuronal apoptosis,and increasing the number of surviving neurons.Thus,the results of this experiment could provide a powerful and weighty objective indication for XST being used during cerebral resuscitation.
