In order to study the value of sequential and quantitative analysis of chimerism in determination of optional time of donor lymphocyte infusion (DLI) and prediction of efficacy of DLI, six patients with leukemias who relapsed or failed of engraftment were treated with DLI. Serial and quantitative analyses of donor chimerism (DC) both prior to and following DLI were performed by multiplex PCR amplification of STR markers (STR-PCR) and capillary electrophoresis with fluorescence detection. The results showed that at the time of relapse or graft rejection, STR-PCR indicated the decreasing donor chimerism in all six patients, at levels ranging from 27.3% to 85.7%. The declining value of DC (<90%) was detected in four patients at 26 days before relapse or graft rejection diagnosed clinically. Therefore the decrease of value of DC can be identified the high risk of relapse or graft failure and can be used to guide DLI implementation at early stage. In this study the clinical response were seen in two patients, the value of DC in these patients increased with convertion to a predominant donor profile (>90%) or converted to stable FDC shortly after DLI, while in the patients without clinical response, the level of DC decreased persistently or declined after transient increase. Three patients without response received second DLI. It is concluded that the monitoring of chimerism is proved to be a valuable to determine the optional time point of DLI and to early evaluate the efficacy of DLI. Furthermore, it can present a rational basis for treatment of intensification in the patients who did not respond to first-line DLI treatment.

BACKGROUNDIt is known that excessive release of glutamate can induce excitotoxicity in neurons and lead to seizure. Dexamethasone has anti-seizure function. The aim of this study was to investigate glutamate-dexamethasone interaction in the pathogenesis of epilepsy, identify differentially expressed genes in the hippocampus of glutamate-induced epileptic rats by mRNA differential display, and observe the effects of dexamethasone on these genes expression.

METHODSSeizure models were established by injecting 5 microl (250 microg/microl) monosodium glutamate (MSG) into the lateral cerebral ventricle in rats. Dexamethasone (5 mg/kg) was injected intraperitoneally at 30 minutes after MSG inducing convulsion. The rats' behavior and electroencephalogram (EEG) were then recorded for 1 hour. The effects of dexamethasone on gene expression were observed in MSG-induced epileptic rats at 1 hour and 6 hours after the onset of seizure by mRNA differential display. The differentially expressed genes were confirmed by Dot blot.

RESULTSEEG and behaviors showed that MSG did induce seizure, and dexamethasone could clearly alleviate the symptom. mRNA differential display showed that MSG increased the expression of some genes in epileptic rats and dexamethasone could downregulate their expression. From more than 10 differentially expressed cDNA fragments, we identified a 226 bp cDNA fragment that was expressed higher in the hippocampus of epileptic rats than that in the control group. Its expression was reduced after the administration of dexamethasone. Sequence analysis and protein alignment showed that the predicted amino acid sequence of this cDNA fragment kept 43% identity to agmatinase, a member of the ureohydrolase superfamily.

CONCLUSIONSThe results of the current study suggest that the product of the 226 bp cDNA has a function similar to agmatinase. Dexamethasone might relax alleviate seizure by inhibiting expression of the gene.

OBJECTIVETo probe the mechanism of EEG activation and Xingnao Kaiqiao, evaluate the actions of cinnabaris and realgar in Xingnao Kaiqiao of Angong Niuhuang pill, guess the significance of cinnabaris and realgar in specific indication treatment of Angong Niuhuang pill, and provide experimental bases for the rationality of Angong Niuhuang pill building-up.

METHODSeventy SD rats were divided into seven groups: the control, the model, the Angong Niuhuang pill (0.4 g x kg(-1)), the Angong Niuhuang pill without cinnabaris and realgar (0.32 g x kg(-1)) , the cinnabaris and realgar (0.08 g x kg(-1)), the realgar (0.04 g x kg(-1)), and the cinnabaris (0.04 g x kg(-1)). Rats in the control and model groups were given distilled water. After three days of administration, the brain damage model was made by Lipopolysaccharides (LPS) injection through caudal vein and the catecholamine (CA) and its metabolites levels in cerebral cortex, included noradrenaline (NE), adrenaline (E), 3-methocy-4-hydroxyphenylglycol (MHPG), 5-hydroxytryptamine (5-HT), 5-hydroxyindoleacetic acid (5-HIAA), dopamine (DA), Homovanlic acid (HVA), 3,4-dihydroxyphenylacetic acid (DOPAC), were determined by high-performance liquid chromatography with electrochemical detector (HPLC-ECD). Influences of Angong Niuhuang pill, Angong Niuhuang pill without cinnabaris and realgar, cinnabaris and realgar on monoamine transmitters were observed in brain damage rats caused by LPS.

RESULTLPS could raise NE, 5-HT, 5-HIAA levels and reduce E, DOPAC levels, but had no influence on HVA, DA, MHPG levels. Angong Niuhuang pill had the trend of raising E, DOPAC levels and reducing NE level, and could reduce 5-HIAA level obviously comparing with models. But Angong Niuhuang pill without cinnabaris and realgar was different, NE level was significantly higher compared to models and Angong Niuhuang pill, DA level was also significantly higher compared to all groups. Cinnabaris and realgar had the same action trends with Angong Niuhuang pill, and separate realgar could obviously reduce 5-HT.

CONCLUSIONInfluence on CA and its metabolites levels in cerebral cortex may be one of the mechanisms of Angong Niuhuang pill's EEG activation, and cinnabaris and realgar have the same action on CA levels in cerebral cortex. The results of the present work allow us to put forward the hypothesis that cinnabaris and realgar are most likely one of the important material basis in Xingnao Kaiqiao of Angong Niuhuang pill.

This study was aimed to investigate the expressions of vascular endothelial growth factor (VEGF) and cyclooxygenase-2 (COX-2) in patients with multiple myeloma (MM) and its clinical significance. Expression of VEGF was detected by enzyme linked immunosorbent assay (ELISA) and the level of COX-2 was detected by Western blot. The results showed that the serum VEGF level of multiple myeloma patients (365.34 +/- 65.63 pg/ml) was higher than that in the normal persons (122.52 +/- 39.29 pg/ml) (p < 0.05); the serum VEGF level of patients at advanced stage (395.07 +/- 54.90) pg/ml was higher than those at stable stage (300.33 +/- 44.22) pg/ml (p < 0.05). The serum Cox-2 positive rate in the patients (31%) was higher than that in normal persons (0%) (p < 0.01); the serum Cox-2 positive rate in the patients at advanced stage (50%) was higher than those at stable stage (21%) (p < 0.01). It is concluded that VEGF and COX-2 may play an important role in the pathogenesis and development of multiple myeloma, they can be used to evaluate the status of patients with MM.

To study the mechanism of thrombogenesis and search new anti-thrombotic agent, the cDNA for human vWF A1 domain was high-level expressed in E. coli and recombinant protein of vWF A1 with biologic activity was obtained. The gene encoding A1 domain was amplified by PCR from plasmid containing full length cDNA of human vWF. After confirming by DNA sequencing analysis, the recombinant expression plasmid pQE31-vWF/A1 was constructed and introduced into E. coli M15 strain, then induced by IPTG; the expressed protein was purified with Ni-NTA agarose, identified by Western blotting. The results showed that the 854 bp DNA fragment was obtained by PCR from the plasmid containing full length cDNA for human vWF and its sequence was identical to the published sequence. High level expression of A1 protein was yielded after 5 hour-induction, which amounted to 30% of total bacteria protein in inclusion body. Western blot demonstrated it possessed good antigenicity and high specificity. It is concluded that cDNA for vWF/A1 had been cloned successfully, high level expression of A1 protein was achieved in E. oli. This study will provide a basis for the further clinical and basic research on the role of vWF in thrombosis and hemostasis.

The interaction among collagen, von Willebrand factor (vWF) and glycoprotein Ib axis is the first step in hemostasis and thrombosis, especially under high shear condition. To develop a new remedy of anti-thrombosis, mRNA from endothelial cells was extracted, and reverse transcription PCR was adopted to amplify DNA of interest. After sequencing, recombinant expression vector was constructed. The amplified DNA fragment of vWF domain A3 was inserted into expression vector with 6 x his taq, pET20b(+), the recombinant was transformed into E coli (strain DE3) and induced by IPTG. Recombinant vWF-A3 was designated as a recombinant fragment comprising residues 918 - 1114 of mature vWF subunit. It was purified through Ni-NTA resin column and refolded in Tris buffer containing GSH and GSSG. The results showed that rvWF-A3 was expressed successfully in E coli (strain DE3), accounting for 46% of total bacterial protein with its purity of over 95%. It was identified that rvWF-A3 is capable to bind collagen and inhibit the wild vWF binding to collagen by competition. It is concluded that rvWF-A3 fragment might be an effective antithrombotic agent for preventing arterial thrombosis.

Objective To study the dynamic changes of cytokines including tumor necrosis factor-alpha (TNF-?),interleukin-6 (IL-6),IL-8 in serum and cerebrospinal fluid (CSF) of asphyxia neonates,and to analyze the relationship between cytokines levels and severity of brain damage and neurological outcome. Methods The concentrations of TNF-?,IL-6,IL-8 in serum and CSF were measured by radioimmunoassay in 63 asphyxia neonates. Neurological development was evaluated at 12 months by children′s developmental scale of china.Results The serum concentrations of TNF-?, IL-6,IL-8 were significantly higher in asphyxiated neonates than those in the controls,and they were correlated with the degree of encephalopathy. The level of serum TNF-? was hig-(hest) at the first day and IL-6 was highest at the third day. There was no marked dynamic changes within 5 days in serum IL-8 level. The concentrations of TNF-?,IL-8 in CSF were higher at the first and the third day.The dynamic changes of IL-6 in CSF were similar in serum and they were positively correlated. The serum concentration of IL-6 in severe brain injury group was much higher than those of normal and mild group.The CSF concentration of IL-6 in severe brain injury group was much higher than that of normal group. The CSF concentration of IL-8 in severe brain injury group was much higher than those of the normal and mild group. Conclusions The concentrations of TNF-?,IL-6 and IL-8 are increased both in serum and CSF in asphyxiated neonates which are correlated with severity of hypoxic-ischemic encephalopathy. Cytokine-mediated inflammatory reactions may participate in the mechanism of hypoxic-ischemic brain injury after asphyxiaion.The concentration of IL-6 in serum and IL-6, IL-8 in CSF are correlated with the neurological outcome.

OBJECTIVETo summarize the surgical effect and clinical application value of esophagectomy with extended 2-field lymph node dissection for patients with esophageal carcinoma.

METHODSFrom June 1987 to December 2008, 1690 patients with esophageal cancer underwent esophagectomy with extended 2-field (thoracic and abdominal) dissection of lymph nodes. Patients with the middle and lower thoracic esophageal cancer underwent Ivor-Lewis esophagectomy, and patients with upper thoracic esophageal cancer underwent Akiyama esophagectomy. 2-field (thoracic and abdominal) lymph node metastases information and the 1, 3, 5, 10-year survival rates were analyzed retrospectively.

RESULTSLymph node metastases were found in 713 patients. The lymph node metastases rate was 42.2% (713/1690).Thoracic lymph node metastasis rate was 39.3% (665/1690), among which in the right pleural apical para-tracheal triangle was 20.7% (349/1690), in the posterior upper mediastinum was 26.3% (444/1690), in the lower mediastinum was 18.2% (307/1690). Abdominal lymph node metastasis rate was 20.1% (339/1690). THE Postoperative complication rate was 16.4% (278/1690), among which the pulmonary complication rate ranking the first, was 43.6% (136/312). The operative mortality rate was 0.2%. The 1-year, 3-year, 5-year and 10-year survival rates were 88.2% (1388/1574), 63.5% (868/1367), 54.8% (705/1287) and 30.8% (232/754), respectively. The 5-year survival rate in patients without lymph node metastasis was 76.2% (448/588), but that in patients with lymph node metastases was 36.8% (257/669).

CONCLUSIONThe results of this study demonstrated that Ivor-Lewis and Akiyama esophagectomy with two-field lymph node dissection exposes the operation fields clearly and make radical lymphadenectomy thoroughly, especially the lymph nodes in the posterior upper mediastinum around the recurrent laryngeal nerve and in the right pleural apical para-tracheal triangle. It is essential that patients with esophageal carcinoma with lymph node metastases should undergo esophagectomy with extended 2-field dissection of lymph nodes. This can elevate the postoperative 5-year survival rate remarkably.
