After half a century of development,liver transplantation has become an important means to solve the problem of end-stage liver diseases and has greatly improved the prognosis of the patients.This article reviewed and summarized the post-operation intensive care management and treatment of complication in children with liver transplantation.

OBJECTIVETo investigate the expression of divalent metal transporter 1 (DMT1) mRNA in male Sprague-Dawley rat heart of different ages and the expression of DMT1 regulated by dietary iron.

METHODSReverse transcriptase (RT)-PCR and Western blot were used in this study.

RESULTS(1)Two isoforms of DMT1 mRNA [with and without iron-responsive element (IRE)] were both detected in rat heart, which were correlated with heart iron content. During development, both of two isoforms of DMT1 mRNA expression were the lowest at the age of PND 7, and increased at PND 21, 63 to 196. (2) After fed with a high iron diet or low iron diet for 6 weeks, the rats developed iron overload or iron deficiency respectively. No significant differences in DMT1 mRNA expression were detected among iron overload, iron deficiency and control rats. By using Western blot analysis, a 21% and 40% reduction in DMT1 protein non IRE form and IRE form respectively were found in iron overload rat (P<0.01, compared with control). Increases (26% approximate, equals 28%) in the levels of two isoforms of DMT1 protein were also observed in iron deficient rat (P<0.01, compared with control).

CONCLUSIONThe level of DMT1 mRNA expression in heart is age dependent;the two isoforms of DMT1 protein may be both regulated by iron on the posttranscriptional mechanism.

OBJECTIVETo observe the clinical effect of self-formulated Tongdatang serial recipe (TDT) in treating antipsychotic drug-induced galactorrhea-amenorrhea syndrome (GAS).

METHODSOne hundred female schizophrenic patients with antipsychotic drug-induced GAS were selected and equally assigned to the treatment group and the control group at random. Both received antipsychotic drug-therapy, but combined with TDT and placebo respectively. The efficacy was evaluated by determining prolactin level before, 4 and 8 weeks after treatment.

RESULTSThe treatment course was completed in 96% of patients. Therapeutic efficacy on the 49 patients of the treatment group was cured in 31 (63.3%), markedly effective in 11 (22.4%), effective in 4 (8.2%) and ineffective in 3 (6.1%), with total effective rate of 93.9%, while in 47 patients of the control group, the corresponding cases (%) was 0, 3 (6.4%) , 7 (14.9%) and 37 (78.7%), respectively, with the total effective rate of 21.3%. Prolactin levels in the two groups were insignificantly different before treatment, it reduced in the treatment group after treatment (P < 0.01), and the decrement in the treatment group was more significant than that in the control group (P < 0.05).

CONCLUSIONSatisfactory effect could achieved by using TDT for treatment of antipsychotic drug-induced GAS.

Aim To evaluate the effects of pantoprazole on various experimental acute ulcer inrats and mice. Methods The model of a gastric ulcer of rats or mice was caused bystree- induced ulcer and ligatel pylurus-induced ulcer. Results & Conclusions At adose of 5, 10, 20 mg? kg-1 of Pantoprazole can markedly decrease the ulcer index ofstree-induced ulcer. Pantoprazole(4, 8, 16 mg? kg -1 ) significantly decrease the areaof ligated pylorus-induced gastric ulcer. It was also found that pantoprazole caninhibit the output of basic gastric acid.

Objective To compare the diagnostic value of renal ultrasound scan (RUS) and 99Tcmdimercaptosuccinic acid (DMSA) renal scintigraphy in children with acute pyelonephritis (APN). Methods In all, 165 children with initial clinical diagnosis of APN, aged from 1.5 months to 11 yrs ( median 20 months), were included in the study, all of which were examined with RUS and DMSA renal scientigraphy. The diagnosis with DMSA renal scientigraphy results was taken as the standard reference to evaluate the diagnostic sensitivity and specificity of RUS. Results Of 99 out of all 330 kidneys that were found abnormal on DMSA renal scientigraphy, 31 were abnormal on RUS. Of the rest normal kidneys on DMSA scans renal scientigraphy, 4 were abnormal on RUS. Thus diagnostic sensitivity of RUS for APN was 31.3%(31/99) and specificity was 98.3% (227/231). Conclusions Although RUS provides with high diagnostic specificity for children with APN, its low sensitivity may underestimate the clinical evaluation of APN.More often than not, 99Tcm-DMSA renal scientigraphy is a clinical necesscity for the definite RUS diagnosis.

Four compounds were isolated from the 70% EtOH extract of Ardisia crispa by using various chromatographic techniques, including silica gel, ODS and semi-preparative HPLC. The structures of 1-4 were elucidated based on physicochemical properties and spectroscopic data. These compounds were defined as crispalactone A (1), (+)-pinoresinol (2), 3,5-dimethoxy-4- hydroxyphenol-1-O-β-D-glucopyranoside (3) and (+)-schizandriside (4). Compound 1 is a new γ-valerolactone derivative, and compounds 2-4 are firstly isolated from Ardisia crispa.

In order to provide the evidences for CD19 as a better antibody targeting molecule for B lineage acute leukemias than CD20 through the multi-parameter flow-cytometry analysis of leukemia cells, the samples from 321 patients with acute leukemia (AL) were immunophenotyped by multi-color flow cytometry and CD45/SSC gating strategy followed by the analysis of CD19 and CD20 expression. The results showed that the positive rate of CD19 (115/116, 99.1%) in 116 cases with B lineage acute lymphoblastic leukemia (B lineage ALL) was significantly higher than that of CD20 (33/116, 28.4%) (P < 0.01); in 17 patients with B lineage/Myeloid (B/My) acute mixed lineage leukemia (AMLL), the former positive rate (17/17, 100%) was also higher than the latter (5/17, 29.4%) (P < 0.01). Both of the two antigens were negative in 29 patients with acute T lymphoblastic leukemia and 7 patients with T/My AMLL. The positive rates of CD19 and CD20 in 152 patients with acute myeloid leukemia (AML) were 7.2% and 2.0%, respectively. The difference of the fluorescence intensity between the two antigens on the cells from each patient with B lineage ALL or B/My AMLL was statistically significant (t = 20.68, P < 0.001). The specificity of CD19 and CD20 in B lymphocytic lineage was 92.3% (132/143) and 92.7% (38/41), respectively, while the sensitivity was 99.2% (132/133) and 28.6% (38/133), respectively, the former sensitivity was significantly higher than the latter (chi(2) = 144.018, P = 0.001). It is concluded that CD19 continuously and steadily express on almost all subtypes of B lineage leukemic cells with homogeneous pattern while only a small number of leukemias express CD20. Both the specificity and sensitivity of CD19 were very high with a much broader reaction pattern than that of CD20 on this group of diseases. These indicate that CD19 may be a better antibody targeting molecule than CD20 for patients with B-lineage acute leukemia.

OBJECTIVETo investigate the effect of S-allyl-L-cysteine (SAC) on isolated rat heart subject to ischemia/reperfusion(I/R) injury and the mechanisms.

METHODSThe isolated perfused rat hearts on a Langendorff apparatus were subjected to global ischemia for 30 min and followed by 120 min of reperfusion. Hemodynamic index, the production of formazan and the level of lactate dehydrogenase (LDH) in the coronary effluent were determined. Superoxide dismutase (SOD) and reactive oxygen species (ROS) in myocardial homogenates were measured.

RESULTSCompared with I/R group, the hemodynamics were greatly improved, the production of formazan was increased, and LDH level in effluent was reduced in SAC group. SAC improved the SOD activity and significantly decreased the level of ROS. In addition, threonine (Thr) attenuated the protective effect of SAC significantly.

CONCLUSIONSAC has protective effect against myocardial ischemia/reperfusion injury on rats. The possible mechanism is that SAC be transported into the cell through alanine-serine-cysteine-transporter 1 (ASCT-1) improves SOD activity and reduces the level of ROS.
