Liver transplantation is a valid treatment option for select patients with Hepatocellular Carcinoma HCC and end-stage liver disease. However, in approximately 20% of patients, recurrent HCC is the rate-limiting factor for longterm survival. Despite identification of clinical parameters that may stratify patients at high risk and exhaustive preoperative staging, cancer recurrence is likely the result of microscopic extrahepatic disease. With a desperate donor organ shortage, locoregional ablation techniques and resection are being employed in patients on the waiting list to serve as a bridge to OLT. Further more, some have advocated aggressive surgical resection of isolated metastasis in both the liver and extrahepatic viscera. Whether these creative strategies confer a survival advantage is unknown, requiring longterm follow-up to determine their efficacy.

Objective To observe the clinical efficacy of Simotang oral liquid combined with compound glutamine enteric capsules in the treatment of diarrhea-predominant irritable bowel syndrome (IBS-D) belonging to liver depression and spleen deficiency pattern, and to explore its possible mechanism. Methods Sixty patients were randomly divided into two groups. The treatment goup (30 cases) took Simotang oral liquid and compound glutamine enteric capsules, the control group took Cerekinon and Medilac-S. The treatment course was 4 weeks. Clinical symptoms, 5-hydroxytryptamine (5-HT) and substance P (SP) of both groups were evaluated respectively before and after treatment. Recurrence rate and adverse reactions were recorded. Results The total effective rate after treating 1, 2, 4 weeks between the two groups had no significant difference (P>0.05). Four weeks later, in the treatment group, total score of the symptoms, abdominal distension and defecation urgency were apparently lower than that of control group (P<0.05). The levels of 5-HT and SP of the two groups significantly decreased after treatment (P<0.05). The recurrence rate at 4 weeks after drug withdrawal of treatment group and control group was 10.7%(3/28) and 32.1%(9/28) respectively. The difference between the two groups wasn’t significant (P>0.05). Obvious side effects were not found in the two groups. Conclusion Simotang oral liquid combined with compound glutamine enteric capsules has evident therapeutic effect on IBS-D of liver depression and spleen deficiency pattern, especially good at releasing abdominal distension and defecation urgency. The mechanism may be related with decreasing the levels of 5-HT and SP.

Stimuli-sensitive drug delivery system (SSDDS) is an novel drug delivery carrier.It is sensitive to either the internal physiopathologic changes (pH,temperature) of the body or external stimulus signal (ultrasound,magnetic signal) and controls the release of the drugs that it carries according to the variation of physicochemical property which stimulated by the signals.SSDDS can be prepared from hydrogels,liposomes and magnetic nanoparticles.In contrast to non-stimuli-responsive drug delivery system,SSDDS has remarkable advantages including feedback regulation,stronger controllability and targeting therapy.This paper will review the advancement in stimuli-responsive drug delivery system in recent years.

Objective To explore the correlations between the levels of glycosylated hemoglobin A1c (HbA1c)and N-Terminal pro-Brain Natriuretic peptide(NT-proBNP)in aged diabetes mellitus(DM)patients with heart failure(HF).Methods 127 patients diagnosed as DM complicated by HF and detected HbA1c and NT-proBNP when admitted into hospital,were divided into three groups according to the levels of HBA1C as follows:group A,4%≤HbA1c≤6.9%;group B,7%≤HbA1≤7.9%;group C,HbA1c≥8%.The levels of NT-proBNP were measured and compared.Results There was no statistical difference between group A and B(P＞0.05),where as the　levels of NT-proBNP in group C increased significantly than that in group A and B(P＜0.01);In group C,HbA1c was linear positively correlated to NT-proBNP(r=0.558,P＜0.01).Conclusion Aged DM patients complicated by HF,the level of HbA1c between 4%and 7.9%was acceptable.Meawhile,HhA1c should the independent risk prediction factor for aged DM patients complicated by HF,which could be used as the guide to the clinical therapy to improve the prognosis.

Rapid prototyping technology, a kind of novel digital prototyping technology developed in mid-1980s based on a principle of discrete and accumulation, which fabricates a prototype by accurate accumulation of material according to the CAD models or CT data under the control of the computer without any other device. In recent years, it has shown a great application prospect in the field of orthopedics combined with three-dimensional image reconstruction of spiral CT and MRL In this article, review is given on the application development of rapid prototyping technology in orthopedics, such as organ model preparation and surgical planning, customized implant and bone tissue engineering porosity scaffold fabrication.

Implant drug delivery system(IDDS) is helpful to the therapy of infection、tuberculosis and tumor of bone. With the development of tissue engineering, various materials has been used as the carriers for the IDDS. Research of the carrier materials used in implant drug delivery system is reviewed in this article.

OBJECTIVE:To establish the content determination method of Icariin in Fucongxiang liquid by HPLC.METHODS:HPLC was performed to determine Icariin on VP-ODS column.The mobile phase was acetonitrile:water(30∶70).Detecting wavelength was270nm.RESULTS:The detected concentration of Icariin was in the good linear range of2.8～28.0?g/ml(r=1.0000),and the average recovery was100.03%(RSD=0.54%,n=5).CONCLUSIONS:The estab-lished method is simple,sensitive,accurate and available for the quality control of Fucongxiang liquid.
