The mortality rate of portal hypertension complicated with variceal bleeding in decompensated liver cirrhosis patients decreased dramatically in recent three decades,mainly benefited from the“forward blood flow”hypothesis proposed in the 1980s and splanchnic vascular tone theory to explain the mechanism of portal hypertension in advanced liver cirrhosis,thereby introducing clinically three types of drugs,namely,somatostatin and its derivatives,terlipressin,and nonselective beta blockers. The abovementioned drugs together with endoscopic variceal ligation, sclerotherapy and histoacryl injection have made a milestone contribution to the dramatic decreasing of mortality rate in liver cirrhosis patients with portal hypertension and bleeding. Recent advances in knowledge on the molecular mechanisms of increase of hepatic portal blood inflow,hepatic sinusoidal endothelium dysfunction and neovascularization form the basis of current emerging therapies for portal hypertension. We can expect that most likely this will result in more effective treatment and prevention for portal hypertension in liver cirrhosis patients.

Acromegaly is an endocrine and metabolic disease with insidious onset. Delays in its diagnosis and treatment significantly increase the incidence of complications. Early detection, diagnosis, and treatment are extremely important for the prognosis of patients with acromegaly. Based on a large quantity of evidence in recent years, Chinese Expert Consensus on the Diagnosis and Treatment of Acromegaly(2020) has standardized the diagnosis and the treatment strategies of acromegaly. In the non-surgical treatment section, according to the categories of drugs used to treat acromegaly, the indications, selection, administration, dosage and precautions of pharmaceutical treatment have been clarified with specific recommendations. It is hoped that the new consensus can further guide and standardize the clinical management of acromegaly.

?7nAChR, an important neurotransmitter recptor,is w il dly expressed in the central and peripheral neuronal system, which is involved i n neuronal signal transduction and the regulation of physiological functions in the central neuronal system. Several studies have demonstrated that ?7nAChR is identified in non-neuronal cells such as endothelial cells, vascular smooth mus cle cells, bronchial epithelial cells, skin keralinocytes and is involved in the regulation of mitosis,differentiation, organization of the cytoskeleton, cell -cell contact, locomotion and migration. These (in vitro and in vivo) s tudies indicated that ?7nAChR participated in the secretion and release of seve ral bioactivity molecules in endothelial cells, mediated intercellular signal tr ansduction, and regulated angiogenesis. These studies suggested an endogenous ch olinergic target for angiogenesis mediated by endothelial ?7nAChR.

【Objective】To observe the jaundice-relieving effect of therapy of clearing heat and draining dampness combined with cooling blood and normalizing gallbladder function for severe icterohepatitis with damp-heat in liver and gallbladder.【Methods】Seventy-one severe icterohepatitis patients with damp-heat in liver and gallbladder were randomized into groups A(n=38) and B(n=33).The two groups received routine basic treatment and symptomatic treatment,group A was treated with heat-clearing,dampness-draining,blood-cooling and bile-draining herbs,and group B with intravenous drip of small-dose 654-2 additionally.Serum levels of total bilirubin(TBil),direct bilirubin(DBil),glutamic pyruvic transaminase(ALT),prothrombin activation(PTA) and jaundice duration were observed for the evaluation of jaundice-relieving effect.Meanwhile,the changes of gallbladder ultrasonograms were observed.【Results】After treatment,serum levels of TBil and ALT were decreased in both groups(P0.05)but the markedly effective rate in group A was higher than that in group B(P

OBJECTIVE:To observe the effect of the side-hole hollow bone cement nail on promoting bone fracture healing. METHODS:This experiment was performed in the Third Hospital of Hebei North College from July 2006 to December 2008. Femoral neck samples were obtained from 60 adult corpses of which the patients were dead one year at most with the mean age of 70 years. X-ray examination showed a significant osteoporosis,but no other abnormalities. Hollow nail was provided by Sanyou Medical Apparatus Co.,Ltd.,Shanghai; self-cohesion methyl methacrylate bone cement was provided by Dental Material Factory,the Second Medical University of Shanghai. In the maximal axial pulling-out force group,the hollow nails were directly implanted into 10 femoral neck samples after drilling at the axial center. The polymethyl methacrylate bone cement was inserted into other 10 femoral neck samples after drilling at the axial center,and the side-hole hollow nail were then implanted. The pulling out experiment was performed by AGS-10KN material testing machine to measure the maximal axial pulling-out strength of hollow nail and the maximal loading when the nail was loose during anti-bending cycle experiments. RESULTS:① The maximal axial pulling-out force of 10 femoral neck samples implanting the hollow nail was 471.5-1 070.5 N,with the mean value of (855.0 ? 207.5) N; the maximal axial pulling-out strength of femoral neck samples implanting the side-hole hollow nail added by poly-methyl methacrylate bone cement was 2 023.7-3 572.1 N,with the mean value of (2 943.3 ? 535.8) N. The maximal axial pulling-out strength in the combined group was significantly greater than hollow nail implantation group (P

OBJECTIVE: To investigate the effect and mechanism of Curcumenol against leukemia and to provide theoretical basis for the development and utilization of Curcumenol.METHODS:Curcumenol liposomes were prepared by mechanical dispersion method and ultrasonic method.MTT method was used to detect the inhibitory effects of Curcumenol and other drug on L1210 proliferation in mice with Lymphocytic leukemia.The apoptosis of L1210 cells induced by Curcumenol was observed under confocal microscope by trypan blue exclusion test and Hoechst 33258/PI double staining.RESULTS: Curcumenol significantly inhibited the proliferation of L1210 cells and induced apoptosis of L1210 cells.CONCLUSION: The anti-tumor effect of Curcumenol is possibly achieved by inducing the apoptosis of L1210 cells.

OBJECTIVE:To probe into the related problems in the application of the cost-effectiveness analysis in pharmacoeconomics METHODS:To discuss the problems in the cost-effectiveness analysis by means of literature metrology,pharmacoeconomic criteria and mathematical proof RESULTS & CONCLUSION:When the cost-effectiveness analysis is adopted in evaluating the economy of drugs,we should especially pay attention to the selection of the clinical treatment indices,the calculation of costs,the usage of the incremental analysis and the comparison with the cost-minimization analysis
