Objective To explore the efficiency of postoperative individualized chemotherapy based on genetic testing results for non-small cell lung cancer (NSCLC). Methods Fifty-six NSCLC patients at stageⅡorⅢA who accepted video-assisted thoracic operation were divided into two groups:the individualized chemotherapy group (n=26) and non individual?ized chemotherapy group (n=30). The fresh lung tumor tissue of individualized chemotherapy group was tested target gene,in?cluding excision repair cross complementing 1 (ERCC1),ribonucleotide reductase subunit M1 (RRM1),β-tubulinⅢ,thymi?dylate synthase(TS),epidermal growth factor receptor (EGFR) and breast cancer gene 1 (BRCA1). The theraputic plan was based on genetic testing results in individualized chemotherapy group, and the non individualized chemotherapy group re?ceiving gemcitabine plus cisplatin. The 1-year disease free survival (DFS), 2-year disease free survival (DFS), the progres?sion-free survival (PFS) and the overall survival (OS) were compared between two groups. Results The 2-year DFS (57.69%), PFS (22.1 ± 5.0 months) and OS (24.1 ± 3.2 months) were significantly higher in the individualized chemotherapy group than those of non individualized chemotherapy group (respectively 30.00%, 18.9 ± 6.2 months, 21.9 ± 4.3 months, P<0.05). There was no significant difference in 1-year DFS between two groups (88.46%vs 83.33%, P<0.05). Conclusion The individualized chemotherapy based on genetic testing results can enhance the 2-year DFS, PFS, OS and the efficiency of postoperative adjuvant chemotherapy for NSCLC.

Objective To research the possible relati onship between exercise-induced HSP72mRNA and ultrastructure of myocardium in rats. Methods 36 SD rats were randomly divided into four groups:control group,one week training group(T1),two weeks training group(T2),three weeks train ing group(T3).The rats in T1,T2 and T3 were trained on treadmill with 75%VO 2ma x intensity for 1 week,2 weeks and 3 weeks respectively.All rats were sacrificed within 24 hours after training and HSP72 mRNA expression of cardiac myocytes we re detected by reverse transcription-polymerase chain reaction(RT-PCR).The chang es of ultrastructure of myocardium in rats were also analyzed by electron micros cope.Results (1)HSP72 mRNA expression in T1 and T2 group were si gnificant higher than controls and T3 group.(2)According to electron microscope results of cardiac myocyte in rats,the sequence of damage degree from slight to severe was T3

0.05). With prolonged of the training period, all the above indexes reverted gradually. Conclusion There might exist an inner correlation between the protective function of myocardium and the expression of myocardial HSP72 mRNA after training.

Objective To investigate the relation of a lipopolysaccharide receptor CD14C-159T gene polymorphism to severe sepsis susceptibility and outcome in postoperation.Methods A prospective,consecutive entry study WSS made among 42 postoperative severe sepsis admitted in neurosurgeon,and 50 health volunteers.The genomic DNA of peripheral blood nucleated was extracted.Typing of each patient for the CD14-159C/T gene polymorphism was performed by restrictive fragment length polymorphism(RFLP).Genotypes were then related to the susceptibility and mortality rate of severe sepsis.Results Development of postoperative severe sepsis increased in patients homozygous for the allele T(78.4%)than that of the allele C(21.6%)(P＜0.05).The mortalitv of sepsis were significantly higher in patients with CD14 homozygous for the T allete(TT)(84.6%)than those with genotype TC (15.4%)and C ailetc(CC)(O).Conclusion The single base pair polymorphism at position-159 in the CD14 gene promoter might influence the development of severe sepsis as well as outcome in postopration.

Objective To investigate the elinieopathologie features of refractory epilepsy. Methods The clinical and pathologic features of refractory epilepsy of 273 cases undergoing surgical treatment in Xuanwu Hospital from January 2005 to December 2007 were reviewed retrospectively. Results The mean age of seizure onset and disease duration were 11.0 years and 11.2 years respectively. The following pathologic subgroups were identified: malformation of cortical development (MCD, 158/273) including focal cortical dysplasia (FCD) type Ⅰ (104, the mean age of seizure onset and disease duration were 11.1 years and 11.2 years respectively), FCD type Ⅱ (30, the mean age of seizure onset and disease duration were 7. 9 years and 12. 7 years respectively) , mild MCD (6) , tuberous sclerosis complex (6) and other types (9) , brain turnouts (26/273, the mean age of seizure onset and disease duration were 14. 5 years and 6. 3 years respectively), ulegyria (63/273), brain infections (13/273), vascular malformation (3/273), cyst (3/273), cholesteatoma (1/273) and other unknown types (6/273). Dual pathology was identified in 31 of 158 MCD cases. Eighty-six of 134 (64. 2%) FCD cases were type Ⅰ B predominantly seen in temporal lobe. Twenty of 26 (76. 9%) brain tumours were mixed neuronal-glial tumours predominantly located in temporal lobe. Cortical dysplasia was often seen in these cases. Conclusions The 3 most common causes of refractory epilepsy are MCD, ulegyria and brain tumours. The predominant subtype of FCD is type Ⅰ B often located in temporal lobe, in which associated hippoeampal sclerosis is often seen. Brain tumors in patients with refractory epilepsy are almost benign neoplasms located in temporal lobe, in which the most frequent type is mixed neuronal-glial tumour.

Objective To study the locations of P-glycoprotein(P-gp),multi-drug resistanceassociated protein (MRP) and lung resistance.related protein(LRP)in brain tissue of focal cortical dysplasia (FCD) and to compare the quantity of these proteins in different brain tissues in an effort to study the mechanism of refractory epilepsy and to provide theoretical basis for medical treatment in patients with epilepsy.Methods The brain tissues of 16 cases with refractory epilepsy were collected during surgery,including 8 cases of focal cortical dysplasia type Ⅰ(FCD Ⅰ)and 8 cases of focal cortical dysplasia type Ⅱ (FCD Ⅱ) Five cases of glioma without history of epilepsy were included as the control group.Envision method was used to observe the location and intensity of expression of these three proteins.Western-Blot was used to analyze these proteins quantitatively.Results In brain tissue,the locations of P-glycoprotein,multi-drug resistance-associated protein and lung resistance-related protein were difierent.P-gp located mainly in capillary endothelial cells;MRP in neurons components;the location of LRP included capillary endothelial cells,balloon cells and the matrix of lesions.The expressions of three proteins in brain tissue of FCD were significantly higher than in control group(P-gp:0.520 ±0.121,MRP:0.132±0.018,LRP:0.092.±0.018,U=0.000,P<0.01).The expressions of P-gp and LRP in lesions of FCD Ⅱ(3.809 ±0.842 and 0.655±0.303,respectively)were higher than that in surrounding regions(2.636 ±0.622 and 0.290±0.096,U value were 6.000 and 4.500,both P<0.01).Conclusions P-gp,MRP and LRP expressed at different position of focal cortical dysplasia,suggesting that their roles were distinctive.

Objective To investigate the clinicopathologic features of the brain tissue from multilobar resection or hemispherectomy for refractory epilepsy. Methods The clinical and pathologic findings of 46 cases seen at Xuanwu hospital from 2005 to 2009 were reviewed retrospectively. Results The mean age of seizure onset and disease duration were 3.9 years and 10.2 years, respectively. There were 33 cases of hemispherectomy and 13 cases of multilobar resection. Temporal lobe abnormality was seen in all cases. The pathologic subgroups were as follows: ulegyria (31/46), malformation of cortical development (MCD, 7/46 ) and infection (8/46). Microscopic examination of ulegyria showed cortical architectural disturbances, neuronal loss, reactive gliosis and appearance of corpora amylacea. We also noted deposition of hemosiderin (13 cases), calcification (9 cases) and island-like neurons (5 cases). All ulegyria cases were accompanied by varying degree of cortical dysplasia, and hippocampus sclerosis were identified in 7 cases. MCD comprised of 5 cases of focal cortical dysplasia ( FCD), including 3 cases of FCDⅠB, 1 case of FCDⅡA and 1 case of FCDⅠA, 1 case of polymicrogyria and 1 case of porencephaly. Among 8 infection eases, there were 5 cases of Rasmussen encephalitis ( RE), l case of cysticercosis, 1 case of tuberculous meningitis and l case of Cytomegalovirus encephalitis. Conclusions The most common pathological category of specimens from hemispherectomy or multilobar resection is ulegyria with obvious temporal lobe abnormality. This is followed by MCD ( with FCDⅠB as the main type) and central nervous system infection (RE as the most frequent abnormality).

Objective To compare the expression and distribution of drug resistance proteins Pglycoprotein (P-gp) and lung resistance protein (LRP) in brain tissues of patients with refractory epilepsy and to investigate the relationship between expression of drug resistance proteins and concentration of antiepileptic drug carbamazepine (CBZ).Methods We included the brain tissues of 26 cases with refractory epilepsy who had in the experiment.They had following pathologic diagnosis: focal cortical dysplasia (FCD) Ⅰb (n =10),FCD Ⅱ a (n =4),FCD Ⅱb (n =2) and brain tumorsincluding ganglioglioma (n =6) and dysembryoplastic neuroepithelial tumor(n =4).Immunohistochemistry staining using EnVision system was used to reveal the expression location of P-gp and LRP,and Western blot in SDS-polyacrylamide gel was used to quantitatively analyze the expression of P-gp and LRP.Fluorescence polarization immunoassay was used to determine concentration of CBZ.Results Both P-gp and LRP performed(μg/ml) prominent overexpression in brain tissues of patients with refractory epilepsy,especially in the lesions of both FCD type Ⅱ (P-gp: 2.593 ±0.829 vs 1.711 ±0.292,t =-2.201,P=0.028;LRP:1.352 ±0.445 vs 1.179 ±0.593, t =-2.516,P =0.028, respectively)and tumor(P-gp:1.567 ±0.092 vs 0.775 ± 0.101, t =2.698, P =0.024; LRP: 1.091 ± 0.239 vs 0.825 ± 0.297, t =3.997, P =0.003respectively).The concentration of CBZ in lesions of brain tumors were lower than which in surrounding regions(0.848 ±0.726 vs 0.948 ±0.785, t =-3.056,P =0.014), while P-gp and LRP were higher than which in surrounding regions in 80％ cases.There was no relationship between expression of drug resistance proteins and concentration of CBZ.Conclusions In processing of drug resistance, P-gp and LRP play important roles.However, there is no correlation between expression of drug resistance proteins and concentration of CBZ, suggesting epilepsy drug resistance to be a complicated mechanism.
