OBJECTIVETo examine the effects of rat marrow stromal cells (rMSCs) on gene expression of local brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) after injection of rMSCs into Cistern Magnum of adult rats subjected to traumatic brain injury (TBI).
METHODSA modified Feeney's TBI model was created in 48 adult rats. rMSCs were harvested from 3-month-old rats, and injected into Cistern Magnum in 24 rats subjected to TBI (Group cell transplantation). Saline was given through Cistern Magnum to another 24 rats subjected to TBI (Group saline control). Animals were sacrificed 1, 2 and 3 weeks after intervention, and special brain tissue blocks were dissected for total RNA extraction from each block. BDNF and NGF mRNA were reverse-transcribed into cDNA and further expanded by polymerase chain reaction (PCR). The expression of target genes was evaluated using semi-quantitative methods.
RESULTSGroup cell transplantation had higher BDNF and NGF gene expressions than Group saline control during a period of less than 3 weeks (P<0.05).
CONCLUSIONSrMSCs transplantation via Cistern Magnum in rats subjected to traumatic brain injury can enhance expressions of local brain NGF and BDNF to a certain extent.

OBJECTIVETo detect alterations of microsatellite loci [transforming growth factor beta receptor II (TGF-betaRII)(A)(10), TGF-betaRII(GT)(3), hMSH3(A)(8), hMSH6(C)(8), Bax(G)(8), IGFIIR(G)(8), IGFIIR(CT)(3)] and point mutations of TGF-betaRII (TGF-betaRII 452/454, TGF-betaRII 533).
METHODSPCR-SSLP, microdissection-PCR-SSLP, PCR-SSCP, clone sequencing and immunohistochemistry were used.
RESULTSThe mutation rate of TGF-betaRII(A)(10) in RER+ (replication error positive) colorectal carcinomas was 33% (3/9). Similar mutations were also observed in adenomas with severe dysplasia. No mutations at other microsatellite loci were found. RER+ colorectal cancers mainly occurred in male patients at a young age and were more common in the colon than in the rectum (P < 0.05).
CONCLUSIONSRER+ colorectal cancers were found in young males and commonly located in the colon. A one third mutation rate in TGF-betaRII(A)(10) in these patients is lower than that observed in western populations, which may imply diverse pathways of carcinogenesis of RER+ colorectal carcinoma. TGF-betaRII(A)(10) mutation may play a role in the transforming process from an adenoma with severe dysplasia to a full blown carcinoma.

OBJECTIVETo assess the reaction of cytokines induced killer (CIK) cells treatment in hematopoietic injury at different levels on patients with benzene poisoning and seek a novel, safe and effective immunotherapy for benzene poisoning.
METHODSCIK cells were in vitro activated by interleukin-2 (IL-2) and granulocyte-macrophage-colony-stimulating factor (GM-CSF) from the peripheral blood mononuclear cells (PBMC). Thirty-two patients with benzene poisoning were treated with CIK cells. Nineteen patients with mild or moderate benzene poisoning in the control group were treated with VitB4, batilol, leucogen, inosine and stanozolol. The results for treatment of 12 patients with aplastic anemia induced by severe benzene poisoning (the efficacy rate and the case fatality rate) were analyzed. The change of T-lymphocyte subset analyzed by flow cytometry was also observed before and after treatment.
RESULTSFor mild or moderate benzene poisoning, the increase of WBC and RLT in CIK group was higher than that in the control group (P < 0.05). The CD(4)/CD(8) levels were significantly increased after CIK treatment. And for severe benzene poisoning, the effective rate of the CIK group was 91.7% and the mortality rate was 0%.
CONCLUSIONCIK treatment is safe and effective for hematopoietic injury caused by benzene poisoning. The mechanism may be related with the immune modulation of CIK treatment on immunodeficiency of patients with benzene poisoning.

OBJECTIVETo study the gene mutation in a patient with multiple exostoses, identify the disease-causing gene mutation.
METHODSPolymerase chain reaction and DNA sequencing were used to screen the EXT1 or EXT2 gene mutation, while mismatch primer amplification and restriction endonuclease digestion were performed to confirm the mutation.
RESULTSBy DNA sequencing, a mutation in the seventh intron was detected and located at 26 bp of 3' splice site upstream in EXT1 gene, which was unreported before. Mismatch primer amplification and restriction fragment length polymorphism analysis suggested that this mutation was not detected in the normal control.
CONCLUSIONThe mutation 1633-26(C-->A) may be the disease-causing mutation in this patient with multiple exostoses.

OBJECTIVETo investigate the results of reconstruction of hypopharyngeal circumferential and cervical esophageal defects with free jejunal transfer.
METHODSRetrospective review of 112 patients who underwent pharyngoesophageal reconstruction with free jejunal interposition. Analysis was confined to the patients with advanced hypopharyngeal, esophageal or recurrent laryngeal squamous cell cancer. Kaplan-Meier method was used to identify the accumulative survival rate.
RESULTSThe free jejunal success rate was 94.6% (106/112). The pharyngocutaneous fistula rate and anastomoses narrow rate were 8.9% (10/112) and 12.5% (12/96) respectively. The perioperative mortality rate was 1.8% (2/112). Except 1 case of dead, 6 cases with flap failure and 2 cases with laryngeal preservation, other 103 cases had resumed oral feeding.
CONCLUSIONSThe success rate of free jejunal transplantation is high and free jejunal interposition is an ideal reconstruction method for patients who have hypopharyngeal circumferential and cervical esophageal defects after tumor resection.

OBJECTIVESTo observe the role of PPARgamma during the activation process of hepatic stellate cells (HSC).
METHODSBy morphology and RT-PCR, we study the changes of expression of PPARgamma in culture-activated HSC or in vivo activated HSC induced by dimethylnitrosamine (DMN).
RESULTSIn vitro, the expression level of PPARgamma in freshly isolated HSC (0.72+/-0.01) significantly reduced to 0.48+/-0.03 on the third day of culture (t = 19.8372, P<0.01), and reduced 70% on the seventh culture-day and could not be detected after the second passage. In vivo, HSC freshly isolated from normal control rats expressed PPARgamma (0.76+/-0.01). During the development of rat liver fibrosis induced by DMN, the expression level significantly reduced to 0.46+/-0.02 after the third injection of DMN (t = 29.5318, P<0.01), and reduced 66% on the end of first week and could not be detected on the end of second and third week.
CONCLUSIONThe expression of PPARgamma might play an important role on the maintenance of resting-form of HSC, and the reduction of expression of PPARgamma might be an early event during the activation process of HSC.
