The liver is an important organ of the body,with an extraordinary capacity for responding to physical or chemical injuries by regenerating. The mechanisms behind liver regeneration are very complicated as hundreds of substances are involved.However,most of them are not liver-specific,such as HGF,EGF etc. We recently isolated a pure protein with hepatic stimulatory activity from the extract of a weanling calf liver and named its hepatopoietin Cn (HPPCn).This paper,with reference to our own work, mainly reviews the development and bioactivity about hepatic stimulator substance(HSS),augmenter of liver regeneration(ALR),hepassocin(HPS) and HPPCn,which are liver-specific biologically active peptides.

Objective To study the mechanisms of Curcumin-induced apoptosis on human gastric cancer cell line SGC-7901.Methods SC,C-7901 cells were treated with various concentrations of Curcumin and the growth inhibition rates of it were accessed by MTT method.Apoptosis of gastric cancer cells were in- spected by flow cytometry.The expression of Fas and survivin in gastric cancer cells were evaluated by west- ern blot.Results Curcumin could effectively inhibit the growth of gastric cancer cells in dose-dependent and time-dependent manners,the sub-peak appeared and the apoptotic rate was increased.The expressions of Fas was higher in Western blot,meanwhile,the expressions of survivin was decreased.Conclusion Curcumin could significantly inhibit the growth and induce apoptosis of gastric cancer cells(SGC-7901),Curcumin could probably through up-regulating Fas and down-regulating surviving to induce apoptosis.

Objective A scientific evaluation of hospital culture with the Dimension organizational culture model, in view of features of China's general public hospitals.Methods Based on Denison model, according to the characteristics of the public general hospitals in China, the authors developed a tool for organizational culture assessment (TOCA) by using the survey data from 87 hospitals in three provinces from the East, Central, and West areas in China.Results This tool, an evaluation scale, comprises the four cultural characteristics of direction, consistency, participation, and adaptability, as well as 13 cultural dimensions of social responsibility and competitive consciousness. The tool is tested as having good internal reliability and validity.Conclusion The TOCA provides hospital administrators with a tool for hospital culture evaluation, diagnosis and improvement.

Objective To probe the effects of nuclear factor kappa B (NF-?B) on cell apoptosis and left ventricular segmental function in acute ischemia repeffusion in dogs.Method Twenty-four dogs were randomly divided into three groups:without left anterior artery (lAD) ligation group (C group),LAD was occluded 30 min following reperfusion 120 minutes in isehemical reperfusion group (IR group),and dogs were administered with PDTC before LAD ligation in ischemical reperfusion plus pyorrole dithitocarbamate group (PDTC group).The left ventricular segmental function was detected by echo cardiography using strain rate anlysis software.EF measured by Simpson's method.Cardiac myocyte apoptosis numbers were determined by terminal deoxynudeotidy transferease-mediated biotinylated deoxyuridine triphosphate nick end labeling (TUNEL).lmmunohistochemistry and western-blot anylysis of NF-?B protein expression.Results NF-?B was obviously expression on injury myocardium of IR group,and increased significantly in contrast to control group (P0.05)Conclusions NF-?B might play an important role in acute myocardial ischemia reperfusion.PDTC reduces myocardial iscbemia/repeffasion injury by preventing expression of factor NF-?B.

Objective To assess the early prognosis of 117 patients after carduopulmonary resuscitation (CPR) in ICU by using the markers of inflammation,Glasgow Coma Scale (GCS) and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) scores.Methods A total of 117 CPR patients admitted between 2010 January to 2012 December were enrolled for study.Within 24 h after admission,inflammatory markers,blood routine items,hepatorenal function,electrolytes of blood were measured.The GCS and APACHE Ⅱ scores were recorded.Arterial blood gas analyses were performed at 0,12,and 24 h after hospitalization,and the 12-h and 24-h lactate clearance rates were calculated.Seven days after treatment,according to the outcomes,the patients were divided into survival group and death group,and the clinical data of two groups were analyzed.Results (1) Of them,73 patients died and 44 survived.Factor analysis showed that age,time elapsed from resuscitation to ICU admission,D-dimer,arterial oxygenation index (FiO2),arterial blood pH,arterial blood lactate concentration upon ICU admission,GCS score and APACHE Ⅱ score were significantly different between the two groups (P ＜ 0.05or P ＜ 0.01); (2) Two classification logistic regression analysis showed that D-Dimer,GCS score and APACHE Ⅱ score significantly correlated with the mortality risk of the patients in the wake of CPR with relative odds ratios of 1.000,2.091,and 0.531,respectively (P ＜ 0.05 or P ＜ 0.01) ; (3) Receiver operating characteristic curve analysis indicated that the area under the curve of GCS (0.821) and APACHE Ⅱ (0.869) had higher predictive value than D-dimer (0.655).The highest accuracy (84.6％) in predicting patient survival was achieved when the GCS score was 6.5.Meanwhile,the highest accuracy (82.1％) in predicting patient death was achieved when the APACHE Ⅱ score was 17.5.Conclusions Both GCS score and APACHE Ⅱ score has obvious correlation with the prognosis of the critically ill patients after CPR and could be used to predict prognosis at early stage.

Objective To evaluate the value of GE′s Q-analysis real-time ultrasonic elastography quantitative analysis software in the diagnosis of breast diseases and explore the best cutoff point of the breast diseases diagnosis.Methods The elastograms of 71 breast lesions(66 patients)were evaluated by using the GE LOGIQ E9 with the Q-analysis software.All the 71 lesions were diagnosed as malignant and benign lesions by surgery or biopsy.The receiver operating characteristic (ROC)curves of the entirety elasticity rate and local elasticity rate was performed.We compared the areas under ROC curves ( AUC) of the two modalities and confirmed the best cutoff point of the breast diseases diagnosis .We also assessed the sensitivity and specificity of the two modalities .Lastly we assessed the ROC curves with Z test to determine whether the difference between the two modalities was significant .Results Among the 71 leisions (66 patients),there were 37 benign lesions and 34 malignant ones.The elastograms of the leisions showed that the elasticity of 37 benign leisions was good ,the hardness value was low and the texture was even .As for the 34 malignant leisions,the elasticity was bad,the hardness value was high and the texture was uneven .The AUC of the local modality was 0.899 ( >0.5).The AUC of the entire modality,was 0.985 ( >0.5).Both modalities were accurate for the diagnosis of breast diseases .When the cutoff point of entirety elasticity rate was set as 3.60,the sensitiveness was 82.4%and the specificity was 86.5%.When the cutoff point of local elasticity rate was set as 2.60,the sensitiveness was 97.1% and the specificity was 91.9%.The difference between the two modalities was significant (Z =2.621,P=0.0088).Conclusions Q-analysis real-time ultrasonic elastography quantitative analysis is able to evaluate the rigidity and texture of tissue and is valuable to distinguish benign breast lesions between malignant breast lesions .The sensitiveness and specificity of local modality are higher than that of entirety modality .
