An innovative approach,named associating liver partition and portal vein ligation for staged hepatectomy (ALPPS),has made possible a marked increase in future liver remnant (FLR) over a short period of time,and has challenged the concept of unresectability.To date,ALPPS has been employed for a variety of primary and metastatic liver tumors from many centers across the world.Many technical variations of ALPPS have been described.However,much controversy has surrounded this procedure,and many problems remain to be solved,such as the reasons for rapid hypertrophy,the technical feasibility,safety and long-term oncologic outcomes,and the result compared with the conventional two-stage hepatectomy.These aspects are needed to be evaluated further in large-scale studies.We believe that the ALPPS procedure will has much room for further development.

A simple, rapid and accurate method is described for the determination of icariin in Fuchun Tablets by reversed-phase high-efficiency liquid chromatography. The samples were first extracted with 70% alcohol for 50 minutes The resulting solutions were chromatographed on aYWG-C18 column.By using a mobile phase of methanoltetrahydrofuran-water (26.5:15.9:56.7) and a detection wavelength at 274 nm, the recovery for 101.02%, CV=2.4%,are obtained.The method can be employed for the quality control of Fuchun Tablets.

Objective To explore the clinical application value of whole-brain CTA-CTP imaging in cerebral arteriovenous malformation (cAVM).Methods Fifteen patients diagnosed with cAVM by CTA-CTP imaging were included in this retrospective analysis study. The angioarchitecture of cAVM lesions were recorded from 4D-CTA images.Using DSA as the golden standard,the diagnostic accuracy of 4D-CTA was evaluated in 13 cases.The perfusion patterns of vessel nidus and peritumoral tissues were analyzed from the CTP images.Bleeding ratios of patients with different angioarchitecture and perfusion patterns were compared.Results 4D-CTA could dynamically display the angioarchitecture details of cAVM lesions and show the whole process of the contrast agent in and out of the vessel nidus.Although the result of 4D-CTA was consistent with that of DSA in most cases,a few fine feeding arteries and draining veins were missed.The nidus in thirteen cases was with high perfusion and the peritumoral tissues were with low perfusion.Another two cases were with low perfusion due to the presence of hematoma.Nine cAVMs suffered from small size,single feeding artery,deep venous drainage and vessel nidus with increased MTT,peritumoral tissues with decreased MTT were more likely to suffer a hemorrhage (P<0.05).Conclusion Whole-brain CTA-CTP imaging could be a valuable adjunct in noninvasive diagnosis of cAVM and predicting the bleeding risk factors.

OBJECTIVE: To evaluate the utilization and its trend of narcotic analgetics in this hospital.METHODS: The use of narcotic analgetics during the period 2005-2007 in our hospital was analyzed retrospectively.RESULTS: The consumption quantity of narcotic analgetics in our hospital increased year-on-year,much as in the consumption of morphine preparations,with oral morphine preparations dominating the 3 first places over the 3 years,however,the increase of pethidine was slowed down in consumption quantity.CONCLUSION: The use of narcotic analgetics in our hospital is rational on the whole,but measures should be taken to tighten the control on the use of narcotic analgetics.

OBJECTIVE:To validate the microbial limit tests of Shuanghuanglian oral liquid.METHODS:The recovery rates of 4 kinds of test organisms including E.coli treated by Shuanghuanglian oral liquid were detected by routine method,culture medium dilution method,and membrane-filter procedure respectively.RESULTS:Shuanghuanglian oral liquid was found to be of bacteriostatic action.The contamination of solution couldn't be detected by routine method.The recovery rate of the test organisms detected by membrane-filter procedure was higher than by culture medium dilution method,but the recovery rates in both methods were all up to the requirement.CONCLUSION:Membrane-filter procedure should be considered preferentially in performing microbial limit test for Shuanghuanglian oral liquid.

Objective To investigate the causes of biliary tract complications after liver transplantation, and to put forward effective measures of prevention, diagnosis and treatment. Methods The literatures of recent years were reviewed and summarized. Results The causes of biliary tract complications after liver transplantation are very complex, and there are no standard preventive measures. Treatment differs according to causes. Conclusion One of the most important causes leading to biliary complications is preservative and ischemic injury. Poorly operative techniques and blood supply to biliary tract are also disastrous. Improving T tube placement can reduce the incidence of biliary complications related with T tube. To prevent biliary complications, it is crucial to completely wash the biliary tract, avoid damaging the blood supply to donor biliary tract and manage perfect biliary mucosa-to-mucosa anastomosis without tension. T tube cholangiography combined with noninvasive MRCP enables accurate depiction of the biliary tree and diagnosis of biliary complications. Doppler ultrosonography should be routinely applied postoperatively. Timely application of interventional radiological technique is a valuable nonoperative procedure for treatment of biliary complications. Meanwhile, biliary sludge or cholestasis and mixed infections of biliary tract should be handled actively and properly.

The presumed consent principle in organ donation as one of the legal systems to obtain organs has a-chieved some success in practice.However,it is controversial in the ethical and legal aspects.Some Chinese scholars express concern about the implementation of presumed consent in the context of Chinese culture.In order to explicit whether the principle of presumed consent in organ donation is suitable for the Chinese culture,this pa-per considered that there are positive factors in promoting organ donation in Chinese culture through the study of the relationship among the types of presumed consent,the presumed consent and informed consent and the ethical prin-ciple of respect for autonomy.Under the regulation and promotion of state law,the principle of presumed consent can also play the positive role in promoting organ donation in the context of Chinese culture.

Systemic juvenile idiopathic arthritis (sJIA) is a systemic inflammatory disease characterized with arthritis in one or more joints,fever,rash and serositis.Due to the atypical symptoms and poor prognosis,it's a great challenge in the clinical diagnosis and treatment efficacy evaluation in sJIA.These challenges could be addressed by the identification of clinical biomarkers,aiming at evaluating the disease severity,predicting the activity and prognosis of sJIA.This review will be focus on genetics,serum and cellular markers in sJIA and summarize the relative application on diagnosis and treatment.

The effects of polysaccharidical peptides (PSP) on the functions of tumour infiltrating lymphocytes (TILs) in vitro was explored. The results showed that PSP, at the concentration of 37-1200?g/ml, promoted the proliferation of TILs in dose-related manner. Combination of PSP with interleukin-2 (IL-2) enhanced the cytotoxicity of TILs and reduced the dose of IL-2 used for activating TILs. The results suggested that PSP could augment the proliferation and cytotoxicity of TILs in vitro.
