Objective To explore the relationship between tumor necrosis factor (TNF) gene polymorphisms in donors and recipients and the incidence and severity of acute graft-versus-host diseases (aGVHD) after unrelated allogeneic hematopoietic stem cell transplantation (alIo-HSCT). Methods Single nucleotide polymorphisms (SNPs) of TNFα-238 (G/A), TNFα-857 (C/T), TNFα-863 (C/A), TNFα-1031 (T/C), TNFβ + 252 (A/G) were analyzed by Multiplex SNaPshot analysis in 76 pairs of donors and recipients. Results Transplantation involving donors with TNFα-857 CC genotype resulted in a higher incidence of grade Ⅱ-Ⅳ aGVHD than donors with CT genotype (91.3% vs 8. 7% , P =0. 039). In the 23 patients with grade Ⅱ-Ⅳ aGVHD, no patients had TNFβ +252 AA genotype, 19 (82.6%) had GA genotype and 4 (17.4%) had GG genotype. There was a significant difference in the distribution pattern of the TNFβ +252 (AA, GA and GG) genotypes in these patients (P =0.03). There was no significant association of TNFα-238 (G/A), TNFα-863 (C/A) and TNFα-1031 (T/C) polymorphisms with the risk of aGVHD. Conclusion These results suggest donor TNFα-857 CC genotype is related to a higher incidence of grade Ⅱ -Ⅳ aGVHD, and patients with TNFβ +252 AA genotype have protection against the risk of grade Ⅱ -Ⅳ aGVHD.

OBJECTIVETo investigate the protective effects of Huperzine A, a potent acetylcholinesterase inhibitor, against the hypoxic ischemic brain damage (HIBD) of the cognitive and morphology in the neonatal rats.
METHODSPostnatal 7 days old rats were given vehicle or Huperzine A (0.05 mg/kg or 0.1 mg/kg, i.p.) following HIBD (unilateral carotid artery ligation followed by hypoxia) or sham operation, and then tested the learning ability and memory in the Morris water maze (MWM) from 36 to 40 postnatal days. The performance in MWM (escape latency, probe time) were recorded to evaluate the learning and memory dysfunction. At the end of MWM trials, the rats were decapitated and their brains were histologically analyzed. The tissue loss in different brain regions including striatum, cortex, and hippocampus were analyzed by image analysis system. The CA(1) subfield neurons numbers were counted to evaluate the brain damage. The acetylcholinesterase histochemistry staining was used to determine the activity of acetylcholinesterase in different brain regions.
RESULTSCompared with sham-operated group, HIBD rats with the vehicle treatment displayed significant tissue losses in the hippocampus (including CA(1) neurons), cortex, and striatum, as well as severe spatial memory deficits (escape latency: 44 s vs 30 s, P < 0.05, probe time: 14 s vs 40 s, P < 0.01). Huperzine A treatment (0.1 mg/kg) resulted in significant protection against both HI-induced brain tissue losses and spatial memory impairments (mean escape latency: 34 s vs 44 s, P < 0.05, probe time: 35 s vs 14 s,P < 0.01). However, Huperzine A treatment (0.05 mg/kg) did not show any significant improvement of spatial memory impairments (mean escape latency: 45 s vs 44 s, P > 0.05, probe time: 17 s vs 14 s, P > 0.05), but moderate to severe brain tissue losses. There was a pronounced reduction of CA(1) neuron density in ipsilateral hemisphere of vehicle-treated group and 0.05 mg/kg Huperzine A group compared with contralateral hemisphere or ipsilateral hemisphere of sham-operated group and 0.1 mg/kg Huperzine A group (72 vs 232, P < 0.01, 72 vs 229, P < 0.01, respectively). There was a close linear correlation between the CA(1) neurons cell number and the mean escape latency for 5 d acquisition trials (r = 0.777, P < 0.01).
CONCLUSIONThe unilateral HI brain injury in a neonatal rat model was associated with cognitive deficits, and that Huperzine A treatment may be protective against both brain injury and spatial memory impairment. Huperzine A showed a therapeutic potential for the treatment of hypoxic-ischemic encephalopathy (HIE) caused by the perinatal asphyxia.

OBJECT:
To obtain values of normal human lung and diffuse pathological changes, in order to provide a simple and convenient diagnostic method for measuring human visceral organs in the autopsy of pathology and forensic pathology.
METHODS:
The exact mass, volume and density of normal and pathological lung were synchronously measured with the intelligentized volume-densimeter made by authors.
RESULTS:
The date-base about the volume and density of human lung with different races were established for anatomy, anthropology and biodynamics. In two cases of over-load in circulation and water toxicosis, the severe lung edema was proved with the scale of lung density, which was atypical edema in the lung tissue.
CONCLUSION
Measurement of visceral organs in the autopsy can assist to an integrative pathological diagnosis.

PCR sequencing ITS genes methods were used to assess the genetic diversity of Morinda officinalis How different populations. The sequence of Morinda officinalis ITS gene was 567 bp in length, and the content of G/C was 64.5%. In this study, 17 haplotypes were obtained, which were at a high level of branching, and the haplotypes of Guangdong population showed to be the expansion origin. The result of the analysis of molecular variance (AMOVA) also showed that the percentage of variation among populations (56.65%) was greater than that within a population (43.35%). The F(ST) value was 0.566 5, and the genetic divergence among populations was significant. Mantel test results also indicated that the level of geneflow was positively correlated with geographic distances (R2 = 0.721 1). The result showed a good correlation between genotype and geographic distribution of Morinda officinalis, and ITS gene sequencing could be useful molecular method for the genuineness and phylogeography of Morinda officinalis.

OBJECTIVETo explore a new method to treat brachial plexus root avulsion experimentally by reimplantation combined with transplantation of neural stem cells (NSCs) modified by neurotrophin-3 gene (NT-3).
METHODSThe total RNA was extracted from neonatal rat striatum and the NT-3 cDNA was obtained by reverse transcription and amplified by polymerase chain reaction. The NT-3 gene was transferred into NSCs via the pLEGFP-C1, an expression plasmid vectors. The untransfected NSCs, the pLEGFP-C1 treated NSCs, and the pLEGFP-C1-NT-3 treated NSCs were transplanted into corresponding spinal cord segment with brachial plexus root avulsion. The survival, differentiation, and migration of the transplanted cells were determined under confocal laser scanning microscope or by immunohistochemistry method. The nerve regeneration was evaluated by gross observation, electrophysiological examination and reverse horseradish peroxidase tracing.
RESULTSThe NT-3 gene was successfully amplified and transferred into neural stem cells via the plasmid vectors. The transplanted cells survived, differentiated, and migrated and NT-3 was expressed within the spinal cord. The animals regained some muscle strength which was less than 3-degree muscular strength according to the British Medical Research Council (BMRC) evaluating system. The results of electrophysiological examination and reverse horseradish peroxidase tracing were superior in the pLEGFP-C1-NT-3 group to the NSCs untransfected group or the pLEGFP-C1 group.
CONCLUSIONTransplantation of NSCs modified by NT-3 gene combined with reimplantation is a relatively effective way to treat brachial plexus root avulsion experimentally. It still need further study to improve the results.
