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.

BACKGROUND: Due to differences in designs and methods,the results of effects of ankle foot orthosis(AFO)on kinematics,kinetics and energy consumption during walking in children with cerebral palsy remain controversial.OBJECTIVE: To explore the effects of AFO on gait characteristics in children with spastic cerebral palsy.METHODS: A total of 21 ambulatory children with cerebral palsy were selected.A plantar pressure gait analysis system was used to perform plantar pressure gait analysis tests of participants when walking with an AFO and without an AFO at the same time of one day,under the same physical condition.All plantar pressure data were recorded,including cadence,cycle time of gait,absolute symmetry index(ASI)of each gait phase,and visualized pressure diagram including dynamic plantar pressure diagram and Center of Gravity's transfer track diagram.Visualized pressure diagrams were described and analyzed.RESULTS AND CONCLUSION: Gait cycle time was shortened in the children walking with an AFO compared with walking without an AFO(P< 0.01).ASI of single-foot supporting phase,swing phase,double-foot supporting phase and gait cycle time of children walking with AFO was significantly reduced compared with children walking without AFO(P < 0.05).Center of Gravity's transfer track diagram of children with cerebral palsy was disordered and could not show as butterfly-shape graphics with good symmetry.After wearing an AFO,the diagram became more ordered.Results show that when wearing an AFO,the gait cycle time in gait was shortened,and the cadence was increased; the symmetry of gait was improved,and the general walking ability was increased.Plantar pressure gait analysis technology can be effectively applied to evaluate the balancing ability of children with spastic cerebral palsy in gait using accurate data and visualized diagrams.

ObjectiveTo study the effect of salmon calcitonin in treating knee osteoarthritis.MethodsFortyeight cases of knee osteoarthritis were randomly divided into four groups,twelve cases each group.A group:acetaminophen+glucosamine hydrochloride,B group:meloxicam+glucosamine hydrochloride,C group:salmon calcitonin + glucosamine hydrochloride,D group:salmon calcitonin.Acetaminophen and meloxicam can stop as pain symptoms disappeared.Other drugs were treated for 12 weeks.A follow up was carried out to compare visual analogue score and 12-item short form health survey.ResultsTwelve weeks later,A,B,C,D four groups' visual analogue score decreased from before treatment 5.6±1.2,5.5±1.2,5.4±1.0,5.1±l.2 to 1.9±0.8,1.2±0.7,0.8±0.6,0.9±0.7,12-item short form health survey score from before treatment - 23.4±3.1,- 23.8±3.0,-24.8 ±3.8,-22.4±2.8 to -15.1±4.7、- 14.5±4.7,-9.3±6.2,-10.2±5.3.There was significant difference before and after treatment in every group(P＜ 0.05).The visual analogue scores of B,C and D group outweigh A group's (P＜ 0.05).A and B groups'scores of 12-item short form health survey were lower to C and D groups' ( P ＜ 0.05 ).ConclusionsSalmon calcitonin can relieve pain in treating knee osteoarthritis.

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 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
