Objective To evaluate the therapeutic effect of Xiao'er Zhixie Paste (XZP) by using the young rat model of chronic diarrhea,and to explore its mechanism.Methods Chronic diarrhea model in young rats was induced by ig senna.Rats were ig with Montmorillonite powder of 1.62 g/kg,XZP of low,medium,and high dose (2.03,4.05,and 8.10 g/kg) for treatment.Loose stools rate,loose stool grade and diarrhea index were determined 1 and 3 d after treatment respectively.The water content of small intestine was measured and blood was collected for testing serum succinate dehydrogenase (SDH),amylase,D-xylose by colorimetric determination,testing serum D-lactic acid,IL-1 β,and TNF-α by Elisa after administration.Results The rate of loose stools in XZP 4.05 and 8.10 g/kg dose group,and diarrhea index in 8.10 g/kg dose group significantly reduced after the first treatment.The loose stools rate of XZP 2.03,4.05,and 8.10 g/kg dose group,diarrhea index,serum D-lactic acid level in 4.05,8.10 g/kg group significantly reduced,and serum D-xylose level in 8.10 g/kg dose group significantly increased 3 d after treatment.However,XZP had no significant effect on SDH,amylase activity and IL-1β,TNF-α levels.Conclusion XZP has obvious therapeutic effect on chronic diarrhea in young rats,the mechanism is to increase improve the absorptive function and permeability of intestinal tract.

Objective To explore the efficacy and safety of ticagrelor plus cilostazol of different dosage in the treatment of low-weight patients after PCI.Methods A total of 148 consecutive ACS patients (body weight ≤ 65 kg) past PCI and with aspirin intolerance were enrolled and randomly divided into four groups.Patients given cilostazol 50mg twice daily plus clopidogrel 75 mg daily were named as the CC50 mg group.Patients in the CC100 mg group were given cilostazol 100 mg twice daily plus clopidogrel 75 mg daily.The TCS0 mg group were given cilostazol 50 mg twice daily plus standard ticagrelor 90mg twice daily and the TC100 mg group were given cilostazol 50 mg twice daily plus standard ticagrelor 90 mg twice daily.All patients were followed up clinically for 6 months.The clinical endpoints were MACEs and bleeding events.Platelet aggregation at 7 and 30 days after treatment the incidence of clinical endpoints during followup were compared between the four groups.Results Patients in the TC100mg group had the lowest platelet aggregation rates tested on both the 7th and 30th day after treatment among all the 4 groups.After 6 months of follow up,the MACEs rate was not significantly different between the four groups (P =0.930).Bleeding events rates in the TC100 mg group the highest among the 4 but without groups significant differences.Conclusions In ACS patients with low body weight ≤ 65 kg) past PCI and with aspirin intolerance,cilostazol 50mg twice daily plus ticagrelor is a safe and efficacious therapeutic regimen.

Objective To assess the efficacy of early detection of breast cancer and the prognostic value of breast self-examination(BSE).Methods Randomized controlled trials(RCTs)involving BSE were included the present meta-analysis based on their qualities.The pooled analysis was performed with RevMany 4.2.8.Results Three RCTs were identified and then they were included the present metaanalysis.In women who conducted a BSE.the rate of biopsy fora lump in breast was 1.27%in the first 5 years,2.47%in more than 5 years but less than or equal to 10 years,and 2.50%in more than 10 years, respectively,all of which were significantly higher than in those who could not conduct a BSE(P<0.05) There was no significant difierence in the rate of final diagnosis and the mortality for breast cancer between the two populations in any follow-up time(P>0.05).Conclusion The rate of biopsy for a lump in breast in women could be increased by a BSE.which should not have been discarded from the early detection of breast cancer completely despite it is not helpful in increasing the rate of final diagnosis and decreasing the mortality for breast cancer.

Objective To study the alteration of hepatocyte growth factor and c-met in the lungs of rats with pulmonary arterial hypertension and its possible underlying mechanisms.Methods Left pneumonectomy plus monocrotaline injection was used for rat PAH model.Rats were executed after measurement of their pulmonary arterial pressure at 1,2, 3 and 4 weeks after MCT injection.Then the right lung and heart were harvested for further analyses.Expression of HGF and c-met was determined by RT-PCR and Western blot.Expression of eNOS and caspase-3 was analyzed immunohistochemically and intrapulmonary TGF-β and ET-1 was analyzed with ELISA.Results Compared with the normal controls, manifestations of right heart hypertrophy and failure, well-elevated pulmonary arterial pressure were observed 28 days after left lung resection and MCT injection.Pulmonary vascular remodeling (i.e., pulmonary fibrosis, hyperplasia of pulmonary arterial endothelial cells and vascular smooth muscle cells in tunica media, as well as decease of vascular density) was observed.Intrapulmonary HGF expression decreased in a time-dependent manner at both mRNA and protein levels 4 weeks after MCT injection, while c-met stayed unchanged.Immunohistochemically, expression of eNOS was reduced and caspase-3 strengthened.On the contrary, ET-1 and TGF-β were obviously up-regulated(P ＜ 0.01).Conclusion Intrapulmonary HGF expression was obviously downregulated in PAH rats, accompanying with reduction of NO and increase of ET-1 and TGF-β expression, while c-met still unchanged.

Objective To explore the effect of early rehabilitation on patients with hand-foot-mouth disease following acute flaccid paralysis. Methods 31 patients with hand-foot-mouth disease following acute flaccid paralysis were in isolation ward of Children's Hospital of Shanxi Province from Aug. 2009 to Oct. 2010. 21 cases of them were given early rehabilitation while 10 cases were divided into control group because their parents refused the rehabilitation intervention. The course was 4 months. Results In the rehabilitation group, 20 cases recovered,1 improved obviously. In the control group, only 1 improved, 9 had no effect. Conclusion Early rehabilitation can improve the motor function of children with hand-foot-mouth disease following acute flaccid paralysis.

OBJECTIVETo explore the effect of Yanghe Huayan Decoction (YHD, a representative recipe for warming yang mass dissipating) in inhibiting precancerosis of breast cancer (PBC) and on the protein and mRNA expression of ki67.

METHODSThe PBC rat model was established by dimethylbenzanthracene (DMBA), and 9 weeks later rats were randomly divided into the blank control group, the model group, the YHD group, the Sanjie Huatan Decoction group (SHD), the Pingxiao Tablet group (PT), and the tamoxifen group. Rats in the model group were administered with water by gastrogavage. Rats in the YHD group received YHD (deglued antler powder 12 g, prepared rhizome of rehmannia 9 g, cassia bark 6 g, white mustard seed 3 g, zedoary root 12 g, appendiculate cremastra pseudobulb 15 g, chekiang fritillary bulb 9 g, licorice root 6 g) at the daily dose of 7.2 g/kg by gastrogavage. Rats in the SHD group received SHD (oldenlandia diffusa 15 g, Scutellaria Barbata 15 g, Trichosanthes Kirilowii 15 g, pinellia 9 g) at the daily dose of 5.4 g/kg by gastrogavage. Rats in the PT group received PT at the daily dose of 144 mg/kg by gastrogavage. Those in the tamoxifen group received tamoxifen at the daily dose of 4 mg/kg by gastrogavage. Pathomorphological changes of the breast tissue were observed by HE staining. The positive rate and the gray value of ki67 expression were detected by immunohistochemical assay. And the expression of ki67 mRNA was detected by q-PCR.

RESULTSCompared with the model group, the general hyperplasia and the occurrence rate of precancerous lesion were higher and the occurrence rate of invasive carcinoma was lower in each treatment group (P < 0.05). Except the SHD group, the intensity of ki67 grey value increased in each treatment group (P < 0.05, P < 0.01). Except the PT group, the positive rate of ki67 and mRNA expression of ki67 increased in the rest treatment groups (P < 0.05, P < 0.01). Compared with the YHD group, there was no statistical difference in the occurrence rate of infiltration or the occurrence rate of precancerous lesion (P > 0.05). The positive rate of ki67 expression and mRNA expression of ki67 increased in the PT group, showing statistical difference (P < 0.05).

CONCLUSIONSYHD could partially inhibit and reverse canceration of breast cancer. It also could inhibit ki67 protein and mRNA expression. Its effect was similar to tamoxifen and superior to PT. So it was suitable for prevention and treatment of precancerous lesion of breast cancer.
