Objective To analyze negative lymph nodes of 34 non-small cell lung cancer(NCLC) patients with total correction by means of fluorescent quantitation PCR and immunohistcchemistry,and to form molecular bi- ology staging.Methods Clinical data and tissue samples of 193 lymph nodes were collected from 34 patients under- going resection for non-small cell lung cancer.Using fluorescent quantitation reverse transcription-polymerase chain reaction(RT-PCR) and immunohistochemistry method,lymph nodes were examined for CEA gene mRNA,P53 and CK to form molecular biology staging.All the patients were followed-up for an average of forty months.Results The CEAmRNA was identified in 21.7% (42/193) lymph nodes negative patients from 17 patients(17/34,50%); TMN staging was up-regulated in 8 patients;positive lymph nodes were increased in 9 patients.P53 and AE1/AE3 were identified 9.8%(19/193) from 11 patients,18.6 % (36/193)from 15 patients,separately;TMN staging was up-regulated in 2 patients of P53 examination and 5 patients of AE1/AE3 analysis;positive lymph nodes were in- creased in in 7 patients of P53 examination and 11 patients of AE1/AE3 analysis.There was obvious statistical sig- nificance in them,but the molecular biology staging based on the three markers was not an independent factor on re- currence and metasis of lung cancer.Conclusion CEAmRNA.P53 and AE1/AE3 analysis could find lung cancer micrometasis more sensitively to form molecular biology staging which was relative to the prognosis,but not an inde- pendent prognostic indicator.It might be good to the therapy strategy after operation.

There are similarities between magnetotactic bacteria and Acidithiobacillus ferrooxidans (A. ferrooxidans) which isolated from Acid mine drainage(AMD). The weak magnetotaxis of some bioleaching bacteria isolated were found by microscope. A magnetophoresis apparatus was designed based on these weak magnetotaxis and be used to analysis the movement of these strains. The physiological properties of the anear magnetic field strain and removed magnetic field strain which isolated successfully by magnetophoresis apparatus have large difference. The nanometer magnetic particles was extract from the Acidithiobacillus ferrooxidans which purified by spread plate method from AMFS and its main elements are Fe and O by energy spectrum analysis. The results show that A. ferrooxidans have weak magnetotaxis and can be isolated by magnetophoresis. With the development of this new isolating method, the research of magnetotactic bacteria and bioleaching will get more benefit from it.

Objective To investigate the hepatoprotective effect of silybin-phosphatidylcholine complex(SPC) in sepsis rats.Me-(thods) Fifty Wistar immature rats were randomly divided into 3 groups:normal control(10 cases),septic group(30 cases) and interfe-(rence) group(10 cases).In septic group and interference group,rats were treated by cecal ligation and puncture(CLP).Meanwhile,the interference group was given SPC before 2 hours of CLP and after 2 hours of CLP.Blood of rats was taken from all groups to determine the levels of serum tumor necrosis factor-?(TNF-?),interleukin-1(IL-1),alanine aminotransferase(ALT) and aspartate aminotransferase(AST) at varying intervals.Results The levels of serum TNF-?,IL-1,ALT and AST after CLP were significantly elevated in septic group compared with the normal control group(P

OBJECTIVETo establish an adolescent violence crime prediction model, and to assess the value of serotonin transporter (5-HTT) gene polymorphism for the assessment and prediction of violent crime.

METHODSInvestigative tools were used to analyze the difference in personality dimensions, social support, coping styles, aggressiveness, impulsivity, and family condition scale between 223 adolescents with violence behavior and 148 adolescents without violence behavior. The distribution of 5-HTT gene polymorphisms (5-HTTLPR and 5-HTTVNTR) was compared between the two groups. The role of 5-HTT gene polymorphism on adolescent personality, impulsion and aggression scale also was also analyzed. Stepwise logistic regression was used to establish a predictive model for adolescent violent crime.

RESULTSSignificant difference was found between the violence group and the control group on multiple dimensions of psychology and environment scales. However, no statistical difference was found with regard to the 5-HTT genotypes and alleles between adolescents with violent behaviors and normal controls. The rate of prediction accuracy was not significantly improved when 5-HTT gene polymorphism was taken into the model.

CONCLUSIONThe violent crime of adolescents was closely related with social and environmental factors. No association was found between 5-HTT polymorphisms and adolescent violence criminal behavior.

OBJECTIVETo observe the preventive effect of rats' serum containing Buyang Huanwu Decoction (BYHWD) on cultured cardiomyocyte apoptosis of neonatal rat induced by means of 24 hrs hypoxia and 4 hrs reoxygenation, and to investigate its mechanism concerned with nitric oxide (NO).

METHODSMyocyte apoptosis was detected by flow cytometry and ELISA with Annexin V-PI double labeled method. The lactate dehydrogenase (LDH) releasing level was measured with ultraviolet spectrophotometer. The NO concentration was determined by modified Yu method and the concentration of thiobarbituric acid response substance (TBARS) was tested by Ohkawa method.

RESULTSBYHWD contained rats' serum could significantly prevent cardiomyocyte from apoptosis induced by hypoxia and reoxygenation. After hypoxia-reoxygenation, the NO, LDH and TBARS levels in the supernatant of cultured liquid treated with BYHWD were significantly lower than those in non-treated cultured liquid, the effect of BYHWD was dose-dependent.

CONCLUSIONBYHWD can prevent cardiomyocytes from apoptosis induced by hypoxia and reoxygenation, its mechanism might be related with oxygen free radical and NO scavenging produced during the hypoxia-reoxygenation process.

OBJECTIVETo probe the recovery mechanism of Zhenggu powder (ZGP) on acute soft tissue injury in cell levels.

METHODSForty rabbits which established animal model of acute soft tissue injury with hammer hitting,were divided randomly into normal group (A), model group (B), vaseline group (C)and ZGP group (D). Injured part was applied external drug daily after model was made. All animals were killed after using drug for 4 days. The local tissue of injured part was taken pathologic study, and was measured the content of IL-1beta, IL-6, TNFalpha by ELISA method and TXB2, 6-keto-PGF1alpha by RIA method.

RESULTSMuscular tissue of group A was normal. But that of group B and C was aberrant,such as swelling and broken of muscular fiber or infiltration of inflammatory cell. Such histological change of group D was lightly and hyperplasia of blood vessel was found. The contents of IL-1beta, TNFalpha, TXB2 and TXB2/6-keto-PGF1alpha in group D were lower than that of group B and group C. On the contrary, the contents of 6-keto-PGF1alpha in the group D were higher than that of group B and group C. The difference of content of IL-6 between groups was not obvious.

CONCLUSIONZGP could promote not only the dilution and the transportation of inflammatory cell factors,but also the repair and the regeneration of the injured tissue structures. The therapeutic effect of ZGP was not relative to IL-6.
