Prognosis analysis of hepatitis B virus recurrence after liver transplantation: a single-center study of 38 cases / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To analyze the prognosis of hepatitis B virus (HBV) recurrence after liver transplantation.</p><p><b>METHODS</b>Thirty-eight patients (37 males; 1 female) with HBV-related end-stage liver disease underwent liver transplantation at our institute between December 1998 and November 2009 and experienced HBV recurrence. Clinical data from pre-transplant and follow-up examinations were retrospectively retrieved from medical records, and included serologic indices of HBV (HBV DNA, markers of liver function) and histological findings from liver biopsy.</p><p><b>RESULTS</b>The median follow-up time was 45.1 months. The median time to HBV recurrence after transplantation was 31.8 months (range: 0.3 to 72.8 months) for histologically benign cases and 13.7 months (range: 0.3 to 66.6 months) for malignant cases. HBV DNA gene mutations were detected in 21% (8/38) of cases. Eighteen patients were treated with entecavir or adefovir, with respect to gene mutations, and HBV DNA fell below 103 copies/ml and liver function became normal. Twenty-two patients died, and causes of death included hepatocellular carcinoma (HCC, n=18), organ failure (n=2), or infection (n=1).</p><p><b>CONCLUSION</b>HBV gene mutations and HCC recurrence were important risk factors for HBV recurrence in our study population. In addition, patients with benign liver diseases who received salvage therapy with adefovir or entecavir achieved a satisfactory prognosis.</p>

Chemical constituents of Trichosanthes kirilowii Maxim / 药学学报

To study the chemical constituents of Trichosanthes kirilowii Maxim., chromatographic methods such as D101 macroporous resin, silica gel column chromatographic technology, Sephadex LH-20, octadecylsilyl (ODS) column chromatographic technique and preparative HPLC were used and nine compounds were isolated from a 95% (v/v) ethanol extract of the plant. By using spectroscopic techniques including 1H NMR, 13C NMR, 1H-1H COSY, HSQC and HMBC, these compounds were identified as 5-ethoxymethyl-1-carboxyl propyl-1H-pyrrole-2-carbaldehyde (1), 5-hydroxymethyl-2-furfural (2), chrysoeriol (3), 4'-hydroxyscutellarin (4), vanillic acid (5), alpha-spinasterol (6), beta-D-glucopyranosyl-a-spinasterol (7), stigmast-7-en-3beta-ol (8), and adenosine (9), separately. Among them, compound 1 is a new compound, and compounds 3, 4 and 5 are isolated from the genus Trichosanthes kirilowii Maxim. for the first time.

Long-term complications after liver transplantation / 中国医学科学院学报

<p><b>OBJECTIVE</b>To investigate the long-term complications after liver transplantation.</p><p><b>METHODS</b>Totally 85 living patients who received liver transplantation from December 30th 1998 to May 28th 2002 in Tianjin First Central Hospital were followed up till October 2007. Liver and kidney functions, blood drug levels, blood pressure, blood sugar, and blood fat were recorded and ultrasound imaging was performed during follow-up.</p><p><b>RESULTS</b>At the end of the study, most patients had experienced one or more complications of prolonged immunosuppressant treatment, including posttransplantation diabetes mellitus (21.18%, 18/85), hypertension (10.59%, 9/85), renal impairment (8.24%, 7/85), hyperlipemia (7.06%, 6/85), hyperuricaemia (7.06%, 6/85), denovo malignancy (2.35%, 2/85), new-onset hepatitis C (7.06%, 6/ 85), recurrent hepatitis B (5.56%, 4/72).</p><p><b>CONCLUSION</b>Recipients of liver transportation often suffers long-term complications, which should be carefully managed to improve their quality of life.</p>
