Objective To observe the treatment effect of Buyang Huanwu Decoction combined with low molecular weight heparin calcium injection in treating deep venous thrombosis (DVT) in lower limb after cesarean section. Methods Seventy-six cases of DVT after cesarean were randomly divided into 2 groups. Thirty-six cases of control group were injected low molecular weight heparin calcium subcutaneously 100 AXaIU/kg twice daily, and forty cases of treatment group were treated with Buyang Huanwu Decoction additionally. After analysing the clinical symptoms and sign before and after treatment, HBV, LBV, PV, FIB, PLT, APTT, TT, PT and indexes of impedance plethysmography, CDFI were observed to evaluate the efficacy. Results After treatment, the total effective rate of treatment group was 97.5%(39/40), and the control group was 77.8%(28/36), the difference was statistically significant (P<0.05). The differences of hemorheological indexes (HBV, LBV, PV, FIB) and impedance plethysmography indexes between before and after treatment in treatment group were statistically significant (P<0.05), while the differences of blood coagulation indexes (APTT, TT, PT) were not significant (P>0.05). No adverse reaction was found during treatment. Conclusion The treatment of DVT after cesarean section with Buyang Huanwu Decoction combined with low molecular weight heparin calcium injection is safe and effective.

Purpose To investigate effect of valsartan on expression of Notch pathway and production of extracellular matrix. Methods Urine protein and production of extracellular matrix were measured after diabetic mice were treated with valsartan. The levels of Jag-ged1, Notch1, Notch intracellular domain 1 (NICD1), transforming growth factor-β1 (TGF-β1), TypeⅣcollagen and Laminin were determinated by immunohistochemistry, Western blot and real-time PCR. Results Valsartan suppressed urine protein and production of extracellular matrix in diabetic mice (P<0. 05). Valsartan also inhibits overexpression of Jagged1, Notch1, NICD1, TGF-β1, Type Ⅳ collagen and Laminin in glomerular tissues of diabetic mice (P<0. 05 or P<0. 01). Conclusion Valsartan inhibits activa-tion of Notch pathway in glomerular tissues of diabetic mice, inhibits production of extracellular matrix in glomerulus and delays glomer-ulosclerosis.

Aging changes of somatostatin (SS) mRNA-positive neurons in the dorsal hippocampus of old rats were studied by in situ hybridization histochemistry and image analysis. In the young rats,SS mRNA-positive cell bodies were mainly located in the pyramidal and polymorphic cell layers of the CA1 and CA2 regions, and in the strata radiatum and polymorphic cell layer of the CA3 region, and in the polymorphic cell layer of dentate gyrus. In the old rats,SS mRNA-positive cell bodies were concentrated in the polymorphic cell layer and denate gyrus. A marked decrease of number of SS mRNA-positive cell bodies and a significant increase of gray value of SS mRNA-positive cell bodies were found in the dorsal hippocampus and dentate gyrus of the old rats as compared with the young rats. No significant age difference in the sectional area of SS mRNA-positive cell bodies was observed in the dorsal hippocampus. The results showed that there were apparent changes with aging of the SS mRNA-positive cell bodies in the dorsal hippocampus of the rats. The significance of the changes remains to be studied further.

Objective To evaluate the protective effect of Bletilla striata polysaccharide ( BSPS) on immunological and chemical liver injury in mice. Methods Thirty Kunming male mice were randomly divided into five groups, including the normal control group,model control group,and low-,middle-,and high-dose BSPS groups (n=6 each).Tail vein injection of ConA was carried out to establish the ConA-induced liver injury model.After different treatments,all the animals were sacrificed,and the plasma levels of ALT and AST were tested.Additionally,sixty Kunming male mice were randomly divided into six groups,including the normal control group,model control group,silymarin group,and low-,middle-,and high-dose BSPS groups (n=10 each).Tail vein injection of CCl4 was performed to establish the CCl4-induced acute liver injury model.After different treatments,the plasma levels of ALT and GSH were tested.The effects of BSPS on the weights of the liver and spleen were examined. Results The levels of ALT and AST were reduced in BSPS-treated mice when compared with those experiencing only ConA-induced liver injury ( model control group) ,and significant difference was found between the middle-and high-dose BSPS groups and the model control group (P<0.01,P<0.05).The weights of the liver and spleen and the level of ALT were reduced in BSPS-treated mice as compared with those with only CCl4-induced acute liver injury (model control group),while the level of GSH was significantly increased in middle-and high-dose BSPS groups (P<0.05). Conclusion BSPS at low,middle,and high doses can prevent against the ConA-induced immunological liver injury and CCl4-induced acute liver injury in mice.

Objective To investigate the radiological features of granulomatous mastitis (GM) in dynamic contrast enhanced MRI (DCE-MRI) and DWI and to differentiate it from the breast cancer in diagnose.Methods Forty five cases of GM and 64 cases of breast cancer confirmed by surgical histopathology or biopsy were retrospectively analyzed in the study.All of the patients were examined preoperatively by DCE-MRI and DWI.Including lesion type,location,enhancement pattern,nipple retraction,supplying arteries,skin thickening and axillary adenopathy in the two groups were evaluated and analyzed by using x2 test.One-way ANOVA was employed to compare the ADC values between the abscess area of GM and non-abscess area,and the difference among the breast cancer lesion area.Dynamic enhancement MR pharmacokinetic parameters were used to measure including early-phase enhancement rate (EER),peak enhancement ratio(Emax),and time to peak ehhancement(Tmax).The statistical differences of EER,Emax and Tmax between the two groups were calculated by using Wilcoxon test.Results In 45 cases of GM,DCE MR images showed nonmass-like lesions (43 patients) and mass-like lesions (2 patients); the nipple involved(16 patients) and segment involved (29 patients);rim-like with heterogeneous enhancement (40 patients) and heterogeneous enhancement (5 patients); nipple retraction (24 patients) supplying arteries dilatation (42 patients),skin thickening (29 patients),and axillary adenopathy (17 patients).Corresponding to the radiological features above,in the 64 breast cancer cases,it showed 54,10,5,59,30,34,16,51,12 and 20,respectively.There were statistical significance between GM and breast cancer in lesion type,location,enhancement pattern,and nipple retraction (x2=67.574,13.075,20.297,20.398 and 23.510,respectively,all P＜0.01).But no differences were existed between 2 groups in supplying arteries and axillary adenopathy(x2=3.928 and 0.502,P＞0.05).EER,Emax and Tmaxin GM were 146.58％,191.13％,195.00 s in GM and 118.13％,159.43％,183.33 s in breast cancer,respectively.Significant statistic differences between GM and breast cancer were found in EER and Emax(Z values were-2.271 and-2.948,P＜0.01).But it did not show significant difference in Tmax (Z =-0.548,P＞0.05).The ADC values of GM on abscess area,non-abscess area,and breast cancer lesion area were (8.0±2.6) × 10-3,(11.3± 1.7) × 10-3 and (8.2± 1.1) × 10-3mm2/s,respectively.There were significant differences in the groups (F=52.167,P＜0.01).Conclusions The characteristic of radiological findings can be found in GM by using advanced MR imaging techniques.DCE-MRI combined with DWI is useful in the differential diagnosis between GM and breast cancer.
