ABSTRACT
Objective To investigate the relationship between the expression of bone sialoprotein(BSP) and the bone metastasis of breast cancer.Methods 840 cases of female breast cancer patients were retrospectively analyzed.The patients were divided into breast cancer bone metastasis group and no bone metastasis group according to whether the patients had bone metastasis after treatment,BSP expression in paraffin specimens of 840 cases of primary breastcancer was determined by immunohistochemical method,x2 test and COX survival analysis was used in analysis of influencing factors of bone metastasis and 5 years survival after treatment of breast cancer.Results 840 cases of breast cancer postoperatively of single factor analysis showed that age,primary tumor size,clinical stage,TNM and molecular typing were statistically significant(P ＜0.05).BSP in bonemetastasis group was significantly higher than that in patients without bone metastasis(non metastasis group and bone metastasis group)(P ＜ 0.05).However,CerbB-2,lymph node metastasis,whether menopause,pathological type,cell grading showed no correla tion.Multivariate analysis revealed that age,tumor volume,clinicalstage,three negative breast and high expression of BPS were risk factors for bone metastasis.COX survival analysis of breast cancer 5 year survival rate,BSP high expression group and low expression group was statistically significant (P ＜ 0.05).Conclusion The clinical stage,age,primary lesion size and molecular type are the main risk factors for bone metastasis after breast cancer treatment.Bone sialoprotein expression is closely related to breast cancer bone metastasis.
ABSTRACT
Objective Discussion the relationship of PALB2 and AR expression in triple negative breast cancer and its clinical pathological features. Methods The SP immunohistochemical staining was adopted to detect the expression of PALB2 and AR in 178 cases of TNBC, PALB2 divided into two groups according to the expression of different, and to analyze the clinical pathological features and prognostic impact of different AR expression status. Results 178 cases of TNBC, that PALB2 missing expression 47 cases (26.4%), AR expression of 60 cases (33.7%), between of them were negatively correlated (-1≤r<1, P<0.05), in PALB2 negative group, AR expression associated with family history, lymph node metastasis, clinical stage and recurrence and metastasis (P<0.05), and 5-year disease-free survival lower than AR negative expression, Log rank = 4.453, P = 0.035. Conclusion PALB2 negative expression while AR positive expression in TNBC have synergistic effect with disease progression, PALB 2 and AR combined detection may provide a new basis for the prognosis of TNBC interpretation, and recommending take further studies to confirm.

Methods 72 patients with ICH from October 2013 to October 2015 in our hospital were selected, and randomly divided into experimental group and control group, 36 cases in each group.The control group used dehydration to reduce intracranial hypertension, improve cerebral circulation, promote nutritional metabolism and anti infection and other conventional treatment,and the experimental group daily intravenous infusion of 1.0 mg of nifedipine on the basis of control group, a course of ten days.The activity dependence, clinical efficacy, MESS score, ICH score, BI score, brain hematoma and brain edema volume were observed and compared between the two groups before and after treatment.Results After treatment, the activity dependence of the experimental group was significantly better than that of the control group ( P <0.05 );the clinical effective rate of the experimental group was significantly higher than that of the control group (P<0.05).BI scores of both groups were increased after treatment, MESS scores were reduced(P<0.05);The BI score of the experimental group was significantly higher than that of the control group (P<0.05),and the MESS score was significantly lower than that of the control group (P <0.05).The volume of cerebral hematoma and the volume of cerebral edema were significantly reduced after treatment in both groups (P<0.05),there was no significant difference in the volume of cerebral hematoma between two groups,there was significant difference in the volume of cerebral edema between two groups (P <0.05).Conclusion Nifedipine can effectively reduce cerebral edema in patients with cerebral hemorrhage, reduce the degree of neurological deficit, improve clinical efficacy.
ABSTRACT
Background and purpose:Triple-negative breast cancer (TNBC) is currently the focus of breast cancer research. Researches demonstrated that the molecular biological characteristics of different ethnic groups are not the same. This study mainly probed into the expression of endothelial growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) in Han and Uygur TNBC patients, and the relationship between the expression and prognosis of patients.Methods:From Jan. 2007 to Jan. 2009, 167 patients were admitted. Among those, 121 were Han and 46 were Uygur patients. The expressions of EGFR, and VEGF were detected by PV-9000 immunohistochemical staining, and compared with lymph node metastasis and clinical staging. The results were analyzed by SPSS 18.0 statistical software.Results:Five-year disease-free survival (DFS) of two groups had no indifferent (P>0.05). EGFR and VEGF positive rate of Han patients was lower than that of Uygur patients (P0.05). Uygur TNBC patients might have a different prognostic factor as compared with Han patients. Further studies need to be carried out.

Conclusion Lyophilizing the long-circulation epirubicin liposomes can effectively improve the stability of the preparation.
ABSTRACT
Objective To investigate whether polymorphism of 102 T/C in 5-HTR2A (serotonin receptor 2A) are associated with Tourette syndrome (TS) in Chinese Han population or none.Methods A total of 101 TS patients and their parents were recruited for the study.The genetic contributions of the 5-HTR-2A 102 T/C polymorphism in 5HTR2A were evaluated using polymerase chain reaction and restriction enzyme digestion (PCRRFLP) and haplotype relative risk (HRR) and transmission disequilibrium test (TDT) statistics.Results The results revealed no significant associations between the 5-HTR-2A 102 T/C polymorphism and TS (HTR-2A 102T/C,TDT =0.353,df=1,P =0.621 ;HRR =1.127,x2 =0.358,P =0.550,95％ CI:0.762-1.666).Conclusion The data suggest that the HTR-2A 102 T/C polymorphism may not be associated with susceptibility to TS in the Chinese Han population.However,these results need to be replicated using larger datasets collected from different populations.
ABSTRACT
Objective To investigate the effect of exercise on calcium modulin in myocardial sarcoplasmic re-ticulum of animal type 1 diabetes model in rat. Methods A total of 40 Spragne-Dawley rats were randomly dividedinto 4 groups : a normal control group, an exercise training group, a diabetes group and a diabetes plus exercise-traininggroup. At the end of 4- week-exercise training after the establishment of the diabetes model by intraperitoncal injectionof sterptozotocin, the animals were sacrificed and the level of blood glucose, insulin, blood fat and glycosylated serumprotein were tested. The gene expression of calcium modulin proteins was measured by reverse transcription-polymerasechain reaction, and the Western blotting technique was used to measure the protein of sarcoplasmic endoplasmic reticu-lure Ca<'2+> -ATPase (SERCA2) and phaspholamban (PLB). Results The level of biochemical indicator of exercisegroup is not affected when comparing with that of the control group, but significantly changed in diabetic group ( P <0. 01 ) ; The level of blood glucose, insulin, blood fat and glycosylated serum protein were ameliorated in diabetic rats inthe exercise training group. No significant changes in mRNA level of SERCA2, PLB and ryanodine receptor type 2(RYR2) were observed between control and diabetic group, the same to protein expression of SERCA2 and PLB. Butexpression of calcium modulin mRNA was significantly increased in exercise group and diabetic rats in the exercisetraining group comparing with that of the control and diabetic groups ( P < 0.01 ), the same to protein expression ofSERCA2 and PLB. Conclusion Exercise exerted good protective effects on the myocardial injury with 1 type diabetesrat, which might attribute to the upregnlated expression of SERCA2, PLB and RYR2 in diabetic rat heart.
