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.

OBJECTIVETraditional detection approaches for non-O157 STEC are both time and labour consuming in diseases surveillance. Virulence genes detection based on multiplex PCR could not only improve the detection efficiency but also increase the accuracy.

METHODSSix virulence genes of non-O157:H7 (stx1, stx2, eae, hly, etpD, katP6) were detected by two groups of trebling PCRs. The multiplex PCRs were optimized by melting curve analysis in SYBR Green I real-time PCR. Testing result of multiplex PCR was consistent with serological testing.

RESULTSThe sensitivity limits of the multiplex PCR for stx1, stx2, eaeP, etpD, katP, and hly were 10 ng/ml, 120 ng/ml, 110 ng/ml,165 ng/ml, 85 ng/ml, and 15 ng/ml, respectively, which is similar with that of single PCR. When the multiplex PCR was applied in 120 adults and 90 children diarrhea samples detection, 13 cases were detected for non-O157 positive.

CONCLUSIONThe method we established can be used for non-O157 STEC virulence genes detection and screening with high efficiency and accuracy.

Objective To investigate the effect of collagen scaffold loaded with collagen-binding domain neurotrophin-3 (CBD-NT3) on the extension of cellular processes of dorsal root ganglions (DRGs), and explore the significance of this kind of combinatorial strategies in the spinal cord injury repair. Methods The tail tendons of SD neonatal rats were performed the removal of cellular components to prepare the collagen scaffold; HE staining was employed to evaluate whether the cells were completely removed from the collagen scaffold. The collagen scaffold was loaded with CBD-NT3,and then, they were co-cultured with primary DRGs for 1, 3 and 5 d, respectively. NT3 and PBS were also co-cultured with primary DRGs for 1, 3 and 5 d, respectively, as controls. Cells on the scaffold were stained by fluorescein diacetate (FDA) for morphology observation and the lengths and angles of the processes in each group were also quantitatively analyzed. Scanning electron microcopy (SEM) was employed to observe the topography of scaffold and the ultrastructure of DRGs 3 d after the co-culture.Results HE staining indicated that the cellular components in the scaffold were removed completely.The length of processes elongation in CBD-NT3 treatment group was significantly longer than that in the controls 3 d after the co-culture (P＜0.05). The 95% confidence interval of the angle between the line which the process emerged from the cell soma to the growing tip of the process and the long axis of fiber was 18.8-20.7 degrees. The results of SEM showed that cells could rely on the topography of the scaffold to anchor and grow. Conclusion The combinatorial strategies of collagen scaffold with CBD-NT3 can play a double function for oriented guiding and inducing extension of cellular processes effectively,which may provide a better therapeutic approach for spinal cord injury repair.
