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.

Conclusion Cx43 and E-cad in breast invasive ductal carcinoma has a certain synergy in the process of the occurrence and development,which related to its metastasis occurred.

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 status of soil fertility of Good Agricultural Practices ( GAP) base for Spatholobus suberectus Dunn. (SSD) in Pingyuan county of Guangdong province, thus to provide reference for GAP research and the subsequent fertilization for SSD. Methods The deep layer and superficial layer of GAP soil were collected for the physiochemical detection and nutrient assay. Compared with the classification standard of the second national general soil investigation, single base soil fertility index was diagnosed and the comprehensive soil fertility was evaluated with modified Nemoro Index. Results The soil pH value and the contents of exchangeable calcium and magnesium were unbalanced, and the contents of macroelements of nitrogen and phosphonium, microelements, and organic matter were low. Therefore, the measures for improving the base soil fertility should be as follows: ( 1) soil amendments of bentonite, gypsum and slaked lime should be used to adjust the soil pH value; ( 2) each plant should be given 10 kg of slaked organic fertilizer as base fertilizer; ( 3) in the process of nurturing, some special micro-fertilizer solution should be used to treat the cut slips, and 5 kg of urea should be used for every 667 meter square of land; ( 4) besides compound fertilizer, every 667 meter square of land should be fertilized with 15 kg of ammonium dihydrogen phosphate for the supplement of nitrogen and phosphorus, and slaked lime and magnesium carbonate should be used for the supplement of soil moderate-quantity elements after transplantation. Conclusion The comprehensive fertility of Pingyuan GAP base for Spatholobus suberectus Dunn. is at low level, and should be improved in combination with GAP requirements.

Objective To investigate the effects of penehyclidine hydrochloride on activities of nuclear factor kappa B (NF-kB) and activator protein-1 (AP-1) during actue lung injury induced by blunt chest trauma-hemorrhagic shock and resuscitation (HSR) in rats.Methods Thirty male Sprague-Dawley rats,aged 8 weeks,weighing 250-300 g,were randomly assigned into 3 equal groups (n =10 each) using a random number table:sham operation group (group S),blunt chest trauma-HSR group (group THSR) and penehyclidine hydrochloride group (group PHCD).The model of actue lung injury induced by blunt chest trauma-HSR was induced by dropping a 300 g weight onto a precordium in anesthetized rats.Blood was withdrawn via the femoral artery 5 min later until MAP was decreased to 35-45 mmHg within 15 min and maintained at this level for 60 min,followed by resuscitation.In PHCD group,PHCD 2 mg/kg was injected intravenously at 60 min after hemorrhagic shock.At 6 h after the model was established,blood samples were obtained for measurement of concentrations of tumor necrosis factor-alpha (TNF-α) in serum.The lungs were then removed for determination of lung water content,myeloperoxidase (MPO) activaty (by colorimetric assay),NF-κB and AP-1 activaties (using electrophoretic mobility shift assay) in lung tissues,and for microscopic examination of pathologic changes (under light microscope).The left lung was lavaged,and lung permeability index (LPI) was calculated.Results Compared with S group,lung water content,LPI,serum TNF-α level and activites of MPO,NF-κB and AP-1 were significantly increased in THSR and PHCD groups.Compared with THSR group,lung water content,LPI,serum TNF-α concentrations and activites of MPO,NF-κB and AP-1 were significantly decreased in PHCD group.The pathological damage to lung tissues was significantly reduced in PHCD group as compared with THSR group.Conclusion PHCD can inhibit activities of NF-κB and AP-1 in lung tissues,thus mitigating acute lung injury induced by blunt chest trauma-HSR in rats.

Objective To evaluate cardiac biomarkers as biological risk factors for cardiovascular and all-cause motality in HD patients.In addition,a multimarker approach including inflammatory index was performed to improve the cardiovascular and all-canse risk assessment of these patients.Methods The author measured Troponin-T (TnT),N-terminal pro brain natriuretic peptide (NT-proBNP) and high-sensitivity C-reactive protein (HsCRP),collected the clinical data at baseline (January 2012) in 229 HD patients in three hemodialysis centers in Haidian District of Beijing,recorded time and cause of death in the next 1000 days.Kaplan-Meier was used to calculate survival rate and impact factors of prognosis.Cox proportional hazard model was used to estimate significance of =TnT,NT-proBNP and HsCRP and adjusted hazard ratios (HRs) of death.Results During the followup,37 patients died,mainly from cardiac cause (54.05％,20/37).Univariate analysis found old age,diabetes,cardiovascular disease,low serum albumin,CRP≥3 mg/L,TnT≥0.1 mg/L,NT-proBNP≥ 4381 ng/L were associated with prognosis.Elevated cTnT,NT-proBNP or HsCRP were all associated with increased cardiovascular and all-cause motality.Moreover,the combination of all parameters (NTproBNP≥4381 ng/L and TnT≥0.1 mg/L and HsCRP≥3 mg/L) were dramatically associated with increased cardiovascular cause mortality (HR=25.25,P ＜ 0.01) and all-cause mortality (HR=27.33,P ＜ 0.01).The association were significant even after full adjustment for cardiovascular (HR=14.33,P ＜ 0.01) and all-cause mortality (HR=1 1.54,P ＜ 0.01) respectively.Conclusions A combined index of cardiovascular risk factors could provide supplementary risk stratification in HD patients for cardiovascular mortality and all-cause mortality,strongly supporting the annual routine determination of these biomarkers.
