Objective To assess whether treatment with compound danshen tablets plus alendronate would be safe and effective in women with postmenopausal osteoporosis. Methods 180 women with postmenopausal osteoporosis were randomized to receive combination therapy and independent therapy with compound danshen tablets and alendronate for 6 months. Scores of VRS were assessed,mean serum alkaline phosphatase, serum osteocalcin, urinary creatinine, urinary hydroxyproline, urinary calcium were detected. Bone mineral density of lumbar vertebra 1 ~5 was determined by dual X - ray absorptiometry. Results Mean serum alkaline phosphatase, serum osteocalcin, and urinary creatinine, urinary hydroxyproline, urinary calcium were statistically different between the combination therapy group and the independent therapy group, and bone mineral densities increased in all therapy groups while there was higher elevated level in the combination therapy group. Conclusions The combination therapy of compound danshen tablets with alendronate has a favorable influence on women with postmenopausal osteoporosis.

Studies in recent years revel that there is a close relationship between gastrin/cholecystokinin-2 receptors (GAS/CCK-2R) and pancreatic cancer. CCK-2R is widely distributed in human body, but not in normal exocrine pancreas. However, CCK-2R is abnormally expressed in pancreatic carcinoma. The abnormal expression of CCK-2R in pancreatic tissues leads to the abnormal protein expression and activation, changes in acinar cells' morphology and phenotype and an increase in the sensitivity to carcinogenic substances. And some GAS/CCK-2R antagonists can be used for the early and late treatment of pancreatic cancer.

Objective To evaluate the value of diffusion registration in diffusion tensor imaging (DTI) through comparing the diffusion tensor data to conduct the two kinds of post-processing methods for obtaining the ADC ,eADC and FA values and the vis-ual neural fiber length .Methods 20 cases of DTI data were analyzed retrospectively .The original data were adopted to directly process for obtaining the ADC ,eADC and FA values respectively ,after exerting diffusion registration the ADC ,eADC and FA val-ues were measured again ,at the same time the two different processing modes were performed the fiber trace imaging ,.The changes of ADC ,eADC and FA values in each case were compared before and after exerting the diffusion registration ,and at the same time the differences of fiber length in the same interest area in the fiber trace image were compared before and after exerting the diffusion registration .Results The difference of the ADC and eADC values obtained before and after exerting the diffusion registration in the normal group showed no statistical significance (P=0 .695 3 ,P=0 .632 1) and the FA value difference between before and after ex-erting the diffusion registration had statistical significance (P=0 .032 1);the difference of the ADC and eADC values obtained be-fore and after exerting the diffusion registration in the clinical patients group had no statistical significance ( P= 0 .203 9 ,P=0 .075 4) ,the FA value difference had statistical significance (P=0 .011 4) ,the visual neural fiber length was elongated after exer-ting the diffusion registration .Conclusion The diffusion registration processing can obtain better quality of ADC ,eADC ,FA images and the fiber trace image ,more reliable ADC ,eADC and FA values ,the visual fiber length is elongated ,which has large application value in MR DTI .

Objective To analyze the fusion genes derived from 29 types of chromosome structural aberrations in leukemia patients,and the significances on the MICM typing,risk grouping,and minimal residual disease(MRD)monitoring of leukemia.Methods The bone ulan-ow or blood samples from 141 leukemia patients were analyzed with a novel multiplex nested RT-PCR.In addition.chromosomal karyotypes were investigated in some patients.Results Of the 141 leukemic samples,66(46.8%)carried 13 types of MLL/AF6,MLL/AF9,dupMLL MLI/ENL,CBFβ/MYH11 and TLS,ERG.Fusion genes were positive in 27 of 57 ALL patients(47.4 q%),and 33 of 78 AML patients(42.3%),respectively.In these ALL or AML patients,7 or 6 chromosome structural aberrations were found. Conclusion This multiplex nested RT-PCR reaction could screen 29 types of chromosome structural aberrations at the same time. It may be helpful for the diagnosis, risk grouping,prognosis evaluation and the detection of minimal residual diseases after chemotherapy and bone marrow transplantation in these leukemia patients.

AIM: To study the apoptosis induction of cyclooxygenase - 2 ( COX - 2) inhibitor, celecoxib and adriamycin (ADM) on tumor apoptosis of gastric carcinoma MGC - 803 cells, and to explore their possible molecular mechanism(s) and interactions. METHODS: The number of MGC - 803 cells was observed by MTT assay. Tumor apoptosis was studied by fluorescence microscopy, flow cytometry (FCM), and DNA ladder. RESULTS: MGC -803 cell number was significantly decreased with increasing dose of ADM. Cells were accumulated in G0/G1 phase and the number of cells in S phase was decreased. ADM (5 mg/L) combined with celecoxib (25 μmol/L) markably inhibited the growth of MGC - 803 cells. Significant morphological changes of typical apoptosis were observed after treatment with combined use of celecoxib and ADM. Compared with ADM or celecoxib alone, ADM plus celecoxib obviously enhanced the DNA ladder fragment revealed by agarose gel electrophoresis of DNA. After exposure to combined celecoxib and ADM treatment for 48 h, MGC - 803 cells were accumulated in G0/G1 phase. There was a decrease in the number of cells in S phase as compared to celecoxib or ADM alone. CONCLUSION: Celecoxib and ADM appear to have synergistic effects for the apoptosis induction. This may be an important prospect for applying COX - 2 inhibitors to assist chemical therapy of ADM in clinical use.

One hundred and twenty stroke patients were randomly divided into rehabilitation group (n =60) and control group (n =60).Patients were assessed with National Institute of Health Stroke Scale (NIHSS) ,Fugl-Meyer Assessment (FMA),Bathel Index (BI) and World Health Organization Quality of Life Assessment Instrument Brief Version(WHOQOL-BREF) before and 6 weeks after treatment by the same doctor.The scores of NIHSS,FMA,BI and WHOQOL-BREF were improved significantly in rehabilitation group after treatment; while those of control group were no improved.The scores after treatment of rehabilitation group were significantly higher than those of control group ( P ＜ 0.05 ).

Five hundred elderly patients with ischemic stroke admitted from January 2008 to December 2010 were enrolled in the study,including 352 recurrent cases and 148 primary cases.There was a positive correlation of stroke recurrence with age,blood pressure,blood glucose and lipid levels,smoking and alcohol consumption of patients(P ＜0.05 ); while the stroke recurrence was negatively correlated with physical exercise(P ＜ 0.05).Stepwise multiple regression analysis indicated that the blood pressure,blood glucose and lipid levels were risk factors for the recurrence of ischemic stroke in elderly patients.

Objective To investigate the expressions of TK1 (thymidine kinase 1) in PHC (primary hepatic carcinoma). Methods TK1 and AFP in serum of 33 cases of PHC (primary hepatic carcinoma), 38 cases of hepatic cirrhosis,36 cases of hepatitis and 35 cases of healthy people were detected by means of Western blot—enhanced chemiluminecence and electrochemiluminescence. Results The difference of TK1 level in PHC group indicated significance when compared with that in hepatic cirrhosis group , hepatitis group and control group (U value was 436.4, 352.1, 163.6, respectively, all P < 0.01). TK1 level in patients with PHC was related with differentiation (χ2 = 7.476,P < 0.05) and TNM stage (χ2 = 7.227,P < 0.05),but not with sex, age, tumor diameter, number of tumors, vascular invasion, lymph node metastasis (P > 0.05). Kaplan-Meier curve analysis revealed that PHC patients with TK1≤ 2.0 pmol/L had a significantly shortened overall survival when compared with those with TK1 > 2.0 pmol/L (χ2 = 3.954,P < 0.05). Multivariable Cox regression analysis indicated that the level of TK1 and TNM stage were the independent risk factors for patients with PHC (all P <0.05). Conclusions The detection of TK1 has a certain clinical value in the diagnosis, monitoring and evaluation of the prognosis of the PHC.
