This study was aimed to investigate the effect of Xiao-Jian-Zhong decoction and its disassembled prescriptions on the content determination of paeoniflorin . A gradient HPLC system was used in the quantitative analysis of paeoniflorin on Diamonsil RP-C18 column ( 250 mm × 4 . 6 mm , 5 μm ) with the mixed solvents of acetonitrile and water . The flow rate was 1 . 0 mL?min-1 and the detection wavelength was 230 nm . The results showed that the content of paeoniflorin had great changes comparing with X iao-Jian-Zhong decoction with its different disassembled prescriptions . The analysis of variance showed that the difference among groups was sig-nificant (P < 0.05). SNKq analysis showed that there was significant difference between groups 6 and 1, 6 and 2 , 6 and 5 ( P < 0 . 05 ) . But no significant difference was existed among group 6 , 3 and 4 ( P > 0 . 05 ) . It was concluded that liquorice and cassia twigs were helpful to the dissolution of paeoniflorin in the decoction . But jujube and ginger had few effects . The content of paeoniflorin in group 5 which does not include maltose was the highest among all groups . It may be due to the fact that paeoniflorin was wrapped in the maltose of X iao-Jian-Zhong decoction .

Idopathic pulmonary fibrosis (IPF),with unknown pathogeny,is a interstitial lung disease. The pathological features are diffuse epithelial-cell lesion and excessive extracellular matrix deposition. Many investigators consider alveolar epithelial cells impairment and abnormal activation,fibroblast proliferation and myofibroblast differentiation as causes,resulting in excessive extracellular matrix disorganization of lung. Recently,it is believed that telomeres and telomerases might play a role in regulating the capacity of fibroblast proliferation and aberrant epithelial repair in IPF. The aim of this article is to review the telomeres,telomerases and their relationship with the idopathic pulmonary fibrosis,furthmore,to identify the etiology and pathogenesis of the idopathic pulmonary fibrosis and provide the study measure for establishing an effective treatment.

OBJECTIVETo evaluate the protective effects of punicosides on alcohol induced acute liver injury in mice and its possible mechanisms as well.

METHODThe 60 mice were randomly divided into normal control, model group, three dose groups of punicosides with low, medium and high, then there is silibinin group. Three dose groups of punicosides and silibinin were given in advance by gavage for 4 weeks, then the mouse model of alcoholic acute liver injury was established. The serum levels of ALT, AST and TG were determined, and the mice were killed to calculate somatic index of liver, thymus as well as spleen. MDA, SOD, GSH-Px and GSH-ST were detected in the liver homogenate. Histopathological changes of the liver were observed by HE staining. The expression of MCP-1 and NF-kappaB in the liver tissues were detected by immunohistochemistry.

RESULTMid and high dose of punicosides reduced the liver index in mice significantly, improved liver steatosis, decreased the level of ALT, AST and TG in serum and the content of MDA in liver homogenate, furthermore the two dose groups increased the activity of SOD, GSH-Px and GSH-ST, inhibited the expression of MCP-1 and NF-kappaB in liver tissue.

CONCLUSIONPunicosides can protect the acute liver damage induced by alcohol.

Objective To investigate the apoptosis of gastric carcinoma SGC-7901 cell induced by histone deacetylase inhibitor(TSA)and to clarify its mechanisms.Methods The apoptosis-inducing role of TSA on gastric carcinoma SGC-7901 cell was investigated with the help of cell proliferation assay,Annexin V stain,cell flow analyzer and Tunel assay.Western blot,gene chips,real time PCR were employed to study the influence and mechanisms of TSA on the expression of gastric carcinoma cell SGC-7901 p53,bax,etc.Results TSA could induce the apoptosis of gastric carcinoma SGC-7901 cells,increase the expression of p53 and bax,and decrease the expression of bcl-2.survivin and easpase in gastric carcinoma SGC-7901 cells.TSA could transfer AIF and EndoG from mitochondria to nucleus.The apoptosis induced by TSA was brought about through the regulation of multiple apoptosis-related genes,and the apoptosis pathway induced by TSA was caspase-independent.Conclusion TSA can induce caspase-independent apoptosis in gastric carcinoma SGC-7901 cell through the regulation of multiple apoptosis-related genes.

OBJECTIVETo investigate the clinical effect and safety of chiropractic in treating cervicogenic sudden hearing loss.

METHODSFrom January 2011 to October 2013, 90 patients with cervicogenic sudden hearing loss were randomly divided into treatment group and control group according to the random number table produced by SPSS 19.0 software. In the treatment group, there were 17 males and 28 females, aged from 31 to 62 years old with an average of (47.57±9.43) years; course of disease was from 1 to 3 days with an average of (1.43±0.68) days; pure-tone audiometry score was from 46.5 to 77.8 dB with the mean of (61.20±9.83) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 17 to 31 scores with an average of (23.46±7.18) scores. In the control group, there were 15 males and 30 females, aged from 28 to 64 years old with an average of (45.77±6.99) years; course of disease was from 1 to 3 days with an average of (1.50±0.73) days; pure-tone audiometry score was from 48.1 to 75.0 dB with the mean of (63.91±8.05) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 20 to 29 scores with an average of (25.61±10.43) scores. The patients of control group were treated with dexamethasone intravenous drip of 10 mg, 3 days later, decreased to 5 mg, 3 days again. And with the methycobal intravenous drip of 500 μg, treatment continued for 10 days. The patients of treatment group were treated with chiropractic additionally except for the therapeutic methods of control group. Chiropractic included local muscle loosening, attacking point, bilateral pulling atlanto-axial joint, and continuous treatment for 10 days. The pure-tone audiometry score and NPQ score were compared between two groups after treatment.

RESULTSAfter the treatment, pure-tone audiometry score and NPQ score in treatment group improved to (40.23± 8.14) dB and (12.70±8.29) scores respectively, which were obviously better than that of control group's (37.70±10.61) dB and (21.24±11.13) scores (P<0.05).

CONCLUSIONCompared with routine method for cervicogenic sudden hearing loss, additional chiropractic can improve hearing and relieve neck pain effectively.

BACKGROUND: Similar to other prosthesis, metal-metal prosthesis would produce plenty of wear particles and metal ions, mainly presented as cobalt (Co~(2+)) and chromium (Cr~(3+)), which can lead to osteolysis, eventually, result in aseptic loosening. OBJECTIVE: To observe the effect of Co~(2+) and Cr~(3+) ions on the cells viability and expression of RANK in rats m0nocyte-macrophage cells (RAW264.7) in vitro. METHODS: Monocyte-macrophage cells (RAW264.7) were cultured in vitro, and then the cells were exposed to Co~(2+) and Cr~(3+) ions. The cell viability was assured by MTT test and the level of RANK Mrna was detected by semi-quantitative RT-PCR at different times. RESULTS AND CONCLUSION: Compared to the control group, MTT test demonstrated that Co~(2+) and Cr~(3+)ions could decrease the cell activity of monocyte-macrophage cells obviously. When the cells were exposed to Co~(2+) Cr~(3+) ions, compared to the control group, the Mrna expression of RANK of the metal ions group was increased at 12 hours (P < 0.05), reached its peak level at 24 hours (P < 0.05), and decreased at 48 hours than that of 24 hours (P < 0.05). The results revealed that metal ions have a cytotoxic effect on monocyte-macrophage cells, stimulate the expression of RANK, and have the potential of facilitating monocyte-macrophages cells transform into osteoclast-like cells.
