Objective To evaluate the efficacy of entecavir treatment on hepatitis B patients with acute-on-chronic liver failure. Methods Eighty-four hepatitis B patients with acute-on-chronic liver failure were treated with entecavir 0.5 mg daily and Other routine drugs. Another 99 hepatitis B patients with acute-on-chronic liver failure were treated with only routine drugs as control. The survival, liver functions, hepatitis B virus (HBV) DNA level, prothrombin time (PT) were observed. The survival rates of patients with early, middle or late stage of liver failure were analyzed. The comparison of rates were done using chi-square test. The numeration data were compared by t test. The survival rates were compared using Kaplan-Meier method. Results Among patients with early stage of acute-on-chronic liver failure, the survival rate in treatment group was 63.3% (31/49), which was significantly higher than that in control group (39.7%, 23/58) (χ2=5.923, P=0.015). Among patients with middle stage of acute-on-chronic liver failure, the surviral rate in treatment group was 63.0% (17/27), which was significantly higher than that in control group (35.1%, 13/37) (χ2=4.854, P=0.028). Among patients with late stage of acute-on-chronic liver failure, four out of eight cases survived in treatment group, while one out of four cases survived in control group. In patients with serum total hilirubin (TBil) level > 342 μmol/L, the survival rate was 56.0% in treatment group, which was significantly higher than that in control group (26.8%) (χ2=9.351,P=0.002). At week 4 of the treatment, the HBV DNA reduction in treatment group was 3. 95 lg copy/mL, which was higher than that in control group (1.78 lg copy/mL) (t=5.847, P=0.001). Conclusions Entecavir treatment could improve the survival rate of hepatitis B patients with early or middle stage of acute-on-chronic liver failure. And the further study with larger population is needed in patients with late stage of liver failure. In addition, entecavir therapy could also improve the survival rate of patients with TBil >342 μmol/L.

Objective To explore the effect of minimally invasive surgery in patients with multiple fractured ribs complicated with traumatic diaphragmatic hernia. Methods Clinical data of 48 patients with multiple fractured ribs complicated with traumatic diaphragmatic hernia from January 2010 to January 2016 were retrospective analyzed. All the patients were divided into control group and observation group according to the operation method, 24 cases in each. Patients in control group were treated with thoracotomy, while patients in observation group were treated by video-assisted thoracic surgery. Results The incision length, operative time, blood loss, postoperative thoracic drainage time and hospital stay in the observation group were significantly lower than that in control group, and the difference was statistically significant (P < 0.05). Patients with fractured ribs of the two groups were cured after bandage fixation and the observation group were treated with no conversion to thoracotomy. Clinical efficiency of the two groups were 91.67% and 79.16% and the overall complication rate was 8.32% and 37.48% respectively, the difference is statistically significant (P < 0.05). Conclusion The video-assisted thoracic surgery in treatment of multiple fractured ribs complicated with traumatic diaphragmatic hernia has advantages of less trauma and blood loss during operation, shorter operation time, faster postoperative recovery, and better curative effect, lower incidence of complications. It can be further promoted and used in clinical.

To study the effect of cholesterol and 25-OH-cholesterol on cholesterol metabolism in HepG2 cells and the effect of coptisine (Cop) extracted from Coptidis Rhizoma (CR) in reducing and regulating cholesterol. In this study, TC, TG, LDL-c and HDL-c were measured by biochemical analysis; mRNA and protein expressions of LDLR, HMGCR and CYP7A1 were detected by qRT-PCR and Western blot. According to the results, cholesterol and 25-OH-cholesterol inducing could decrease in mRNA and protein expressions of LDLR and CYP7A1, so as to increase TC and LDL-c contents. However, Cop could up-regulate mRNA and protein expressions of LDLR and CYP7A1 and down-regulate that of HMGCR, so as to reduce TC and LDL-c levels. These findings suggested that Cop has potential pharmacological activity for reducing cholesterol, and may reduce cholesterol by regulating mRNA and protein expressions of key genes involved in cholesterol metabolism, such as LDLR, CYP7A1 and HMGCR. This study laid a firm theoretical foundation for developing new natural drugs with the cholesterol-lowering activity.

Aconitum, as a kind of common traditional Chinese medicine, contains multiple biological active substances, with a very high medicinal value but high toxicity. Its major toxic ingredients are aconitine, mesaconitine and hypaconitine, which are also efficient ingredients. Therefore, the safety of its clinical application has aroused wide attention. With the constant deepening of drug development studies, people want to learn about its toxic mechanism and the regularity of its emergence and development of its toxicology, so as to make a scientific and rational assessment for its safety. Therefore, toxicokinetics and metabonomics have gradually become important content in the new drug assessment. During the development of drug performance, it is crucial to establish a scientific, objective and standardized Aconitum safety evaluation system and correctly assess and utilize its toxicity. Having summarized studies on metabonomics and toxicokinetics of Aconitum drugs in recent years, authors proposed to strengthen the studies on Aconitum drug safety assessment and establish a scientific and standardized safety evaluation system as soon as possible, in order to make the national treasure more useful.

BACKGROUND:Some studies have demonstrated that red blood celllysate added into the bone marrow can increase the efficiency of isolating and purifying mesenchymal stem cells, in order to obtain high-purity and high-quantity bone marrow mesenchymal stem cells.
OBJECTIVE:To isolate and culture bone marrow mesenchymal stem cells of rabbit with red blood celllysis in vitro for exploring proliferation characteristics and performing the biological identification of cells.
METHODS:Bone marrow suspension was col ected by puncturing the tibia with medul o-puncture needle. Red blood celllysis was added to the bone marrow suspension, and bone marrow mesenchymal stem cells were isolated and cultured. Numbers of primary cells were recorded at 4, 7, 10, and 13 days later And Growth curves of the cells at passages 2-5 were drawn for comparison of proliferative characteristics. Inverted phase contrast microscope was used to observe the morphological changes of cells. CD34, CD44 antigens of bone marrow mesenchymal stem cells were identified by flow cytometry and immunity fluorescence.
RESULTS AND CONCLUSION:The adherent bone marrow mesenchymal stem cells mainly showed s spindle shape, with homogeneous nuclei, prominent nucleoli, and rich cytoplasm, which were positive for CD44 antigen and negative for CD34 antigen. The primary cells exhibited an“S”shape. Passage 4 cells had a better proliferative ability, rapider growth and more counting of cells as compared with other generations. These findings indicate that red blood celllysis method is a feasible ways of culturing bone marrow mesenchymal stem cells 0 in vitro, and passage 4 cells have the strongest proliferation capacity.

Objective To investigate the level of serum macrophage migration inhibitory factor (MIF) and its correlation with serum precollagen Ⅲ peptide (PⅢP) and tissue inhibitor of metalloproteinase (TIMP)-1 in patients with chronic hepatitis B (CHB) and hepatitis B virus (HBV)-related cirrhosis. Methods Forty-four CHB patients (hepatitis B group), 44 patients with HBV-related cirrhosis (cirrhosis group) and 30 healthy controls (control group) were enrolled in this study. The venous blood was collected and MIF level was detected by enzyme-linked immunosorbent assay (ELISA). Correlations between MIF and PⅢP, TIMP-1 were analyzed in observed groups. Comparison between groups was done using t test. The correlations between MIF level and alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), plasma thromboplastin antecedent (PTA), PⅢP and TIMP-1 were analyzed by rectilinear correlation. Results The levels of serum MIF, PⅢP and TIMP-1 in CHB group and cirrhosis group were all significantly higher than those in control group (t=12.87,5.28, 10.98,t=11.22,14.84,11.17;all P<0.05), while there were no significant differences between CHB group and cirrhosis group (t= -1.05,1.52,--2.07;all P>0.05). There was no correlation between MIF level and ALT, AST, TBil and PTA. MIF level in CHB patients with hepatitis B e antigen (HBeAg) positive and high viral load were both higher than that in patients with HBeAg negative and low viral load. MIF level was both positively correlated with PⅢP level in CHB group and cirrhosis group (r=0. 603, P<0.05 and r=0. 415, P<0. 05, respectively). MIF level was also positively correlated with TIMP-1 level in CHB group (r=0. 458, P<0.05), while not correlated in cirrhosis group (r=0. 210, P>0.05). Levels of PⅢP and T1MP-1 were both correlated in CHB group and cirrhosis group (r=0. 849, P< 0.05 and r=0. 424, P<0.05, respectively). Conclusions The levels of serum MIF are significantly increased both in patients with CHB and cirrhosis. The early production of MIF might be related with viral replication, but not with liver function. MIF participates in formations of hepatitis, liver fibrosis and cirrhosis, which could reflect the degree of liver cirrhosis.

Objective To increase the understanding in protein-losing enteropathy (PLE).Methods Sixty-one PLE patients were enrolled in the study and the clinical characteristics, complicated disease, diagnosis and treatment were analyzed. Results The age of the patients was 16-77 (40±15)years, and the gender ratio was 35:26 (female: male). The main clinical manifestations were bilateral lower limb edema in 51 cases, ascites in 41 cases, bilateral pleural effusion in 23 cases, pericardial effusion in 13cases, abdominal pain in 16 cases and diarrhea in 33 cases. The prominent abnormality in laboratory examinations was hypoalbuminemia. The underlying diseases include systemic lupus erythematosus (SLE) in 28 cases, intestinal lymphangiectasia in 12 cases, hepatic cirrhosis in 5 cases, heart diseases in 5 cases,Crohn's disease in 3 cases, membranous nephropathy in 2 cases, Budd-Chiari syndrome in 1 case. Four cases happened after abdominal operation and 1 case after radiation therapy of gastric cardia cancer. Thirtyseven cases were diagnosed by 99Tcm-labelled human serum albumin scintigraphy and 24 cases were diagnosed clinically. Treatment was focused on underlying diseases. The clinical manifestations in 21 cases of SLE improved after SLE was controlled. In 2 cases of intestinal lymphangiectasia and one with Crohn's disease, the clinical manifestations improved after surgery. The other patients had no improvement.Conclusions PLE was not uncommon in clinical practice. Its predominant characteristics were severe hypoalbuminemia, edema and dropsy of serous cavity. PLE can complicate other diseases such as SLE,intestinal lymphangiectasia. Treatment should be focused on primary disease.

To collect small molecule drugs and their drug target data such as enzymes, ion channels, G-protein-coupled receptors and nuclear receptors from KEGG database as the training sets, in order to establish drug-target interaction models based on the random forest algorithm. The accuracies of the models were evaluated by the 10-fold cross-validation test, showing that the predicted success rates of the four drug target models were 71.34%, 67.08%, 73.17% and 67.83%, respectively. The models were adopted to predict the targets of 26 chemical components and establish the compound-target-disease network. The results were well verified by literatures. The models established in this paper are highly accurate, and can be used to discover potential targets in other traditional Chinese medicine ingredients.
