The research result industrialization means the scientific research results of the laboratory transfer into productive force,a realistic production,in the market.The management for the research result industrialization should improve further the service in order to promote the industry progress.This paper presented the status quo of our country research achievement transformation and compared with research result industrialization of the developed countries,and point out the mode of combination of production,education,and research and the different research result transformation mode would effect the transformation rate of the research results.Meanwhile,some related solutions under current condition were suggested in the paper.

Objective To research the electrocardiogram (ECG) manifestations of common electrolyte disturbance and to discuss the accuracy of ECG diagnosis. Methods One hundred and sixty-nine hospitalized patients with hyperkalemia and 170 patients with hypokalemia were selected and the results of ECG were analyzed. Results In mild hyperkalemia patients (serum potassium concentration 5.5- 6.5 mmol/L), the ECG abnormal rate was 91.4% (64/70). In mild hypokalemia patients (serum potassium concentration 3.0-3.5 mmol/L), the ECG abnormal rate was 56.9% (41/72). There was significant difference (P < 0.05). The greater the deviation of serum potassium concentration, the more obvious the characteristic changes of ECG. Conclusions In addition to the blood biochemical test, ECG is also a kind of check tool that can help to diagnose abnormal blood potassium.

Objective To investigate the mRNA expression of survivin, livin and XIAP gene in peripheral blood of patients with gastric cancer and its relationship with clinico-pathological features.Methods This study included 50 patients with gastric cancer and 20 healthy donors. The expression of survivin, livin and XIAP gene was detected by reverse transcription-quantitative polymerase chain reaction (RT-QPCR) using a molecular beacon probe, while recombination plasmid containing the sequence of survivin, livin and XIAP was standard. The relationship between copies of survivin, livin and XIAP gene expression in peripheral blood with gastric cancer and clinical data was analyzed. Results A linear standard curve was obtained between 103 ～ 1010 copies. The copies of survivin, livin and XIAP mRNA in peripheral blood of patients with gastric cancer did not correlate with gender, age, and histological types ( P ＞ 0.05). There were positive relationships between copies of survivin, livin and XIAP gene with lymph node metastasis and TNM stage (P ＜0.05 ). The expression of survivine, livin and XIAP was all negative in peripheral blood of healthy people. 52% (17/33) of patients suffered from recurrence or metastasis who had positive expression of survivin and/or livin and/or XIAP mRNA, while it was 18% (3/17)among the negative survivin and/or livin and/or XIAP mRNA caces ( P ＜ 0.05). Conclusions The expression of survivin, livin and XIAP mRNA can be used to detecte micro-metastasis in peripheral blood circulation of gastric cancer.

Objective To investigate the diagnostic value of microRNA (miRNA) in peripheral venous blood for depressive disorder.Methods Real-time fluorescence quantitative PCR (RT-qPCR) was used to verify expression level of miRNAs in peripheral blood of non-specific mental retardation children,which were aberrantly expressed in depressive disorder patients,and then Receiver Operating Characteristics (ROC)curve was employed to confirm the sensitivity and specificity of abnormal miRNA expression in depressive disorder and non-specific mental retardation.Results MiR-1972,miR-26b,miR-4485,miR-4498 and miR-4743 were upregulated significantly in case group of depressive disorder(P＜0.05),meanwhile miR-4485 and miR-4743 in aforementioned 5 miRNAs also upregulated significandy in patients of non-specific mental retardation(P＜0.05),but miR-26b showed no significant difference between case group of non-specific mental retardation and the control group (P＞0.05).The ROC curve of miR-26b in depressive disorder patients and their control group showed that the sensitivity and specificity were 0.609,0.664 respectively,and the area square under the curve was 0.614(P=0.021).The ROC curve of miR-26b in patients of depressive disorder and non-specific mental retardation indicated that the sensitivity and specificity were 0.784 and 0.471,and area square under the curve was 0.643 (P=0.003).Conclusion miR-26b probably have diagnostic value for depressive disorder,which may comorbidity with non-specific mental retardation.But genetic and psychosocial mechanism of comorbidity still needs further exploration.

AIM:To detect the endogenous expression of B-cell leukemia/lymphoma 6 member B (BCL6B) in FHC and LoVo cells, and to investigate the effects of BCL6B on proliferation and migration of LoVo cells for further explo-ring the underlying mechanism .METHODS:The endogenous expression of BCL 6B in the FHC and LoVo cells was detec-ted by RT-PCR and Western blot .The methods of MTT assay , colony formation assay , wound healing assay and Transwell chamber experiment were employed to examine the biological functions of BCL 6B in the LoVo cells.The mRNA and protein levels of BCL6B, cyclin D1 and matrix metalloproteinase-9 ( MMP-9) were determined by RT-PCR and Western blot , re-spectively.The level of phosphorylated protein kinase B (p-AKT) was detected by Western blot.RESULTS:BCL6B ex-pression was notably repressed in the LoVo cells as compared with the FHC cells , which were significantly increased by transfection with pcDNA3.1-BCL6B.The abilities of proliferation and migration of the LoVo cells at 72 h were inhibited by 28.33%(P<0.01) and 36.11%(P<0.05) in BCL6B group.The mRNA levels of cyclin D1 and MMP-9 in the cells of BCL6B group were decreased by 39.90%(P<0.01) and 77.36% (P <0.05), and the protein levels of cyclin D1, MMP-9 and p-AKT were reduced by 44.00%(P<0.05), 47.06%(P<0.01) and 32.88% (P<0.05), respectively. CONCLUSION:BCL6B inhibits proliferation and migration of the LoVo cells , and the PI3K/AKT signaling pathway is in-volved in this process .

Objective To evaluate hepatitis B virus large surfsce protein(LHBs) in monitoring of antiviral treatment.Methods LHBs.HBV serum markers and HBV DNA loads in 46 patients with adefovir dipivoxil(ADV) therapy were monitored for the whole course(60 weeks).Enzyme linked immunosorbent assay(ELISA),time differentiate immunofluoresence assay and real.time polymerase chain reaction(RT-PCR)were performed to detect LHBs,HBV serum markers and HBV DNA loads,respectively.And correlation analysis was also performed.Results Both LHBs and HBV DNA declined during the ADV treatment.and the correlation coefficient was 0.97.but LHBs declined after HBV DNA.There were 20 patients with HBV DNA<5×102/mL at 60th week.in which 8 were LHBs negative;in 14 recurrent patients,the HBV DNA turned to negative and became positive again,3 with negative LHBs;while in 12 patients resistant to the ADV therapy.2 were LHBs negative.Conclusion Dynamic monitoring of LHBs is useful in the evaluation of antiviral treatment.

Objective To investigate the feasibility of induction of experimental chronic pancreatitis rat model with L-arginine.Methods Animals were randomly divided into control group,arginine 12 h group,arginine 24 h group and arginine 7 d group with 10 rats in each group.L-arginine solution was intraperitoneally injected twice with an interval of 1 h.Serum amylase and glucose levels at corresponding time points were detected and histopathological scores of pancreas were evaluated.Collagen in pancreas was stained with Van Gieson method.Results Serum amylase levels were (1 634±890 ) U/L,( 3 872±2 676 ) U/L,( 3 307±2 197)U/L and (1 561±304) U/L in control group,arginine 12 h group,arglnine 24 h group and arginine 7 d group,respectively.The serum amylase level in arginine 7 d group was significantly lower than those in arginine 12 h group and arginine 24 h group (P ＜ 0.05 ).There was no significant difference in serum glucose level among all the groups.Histopathological scores were 0.8±0.4,5.1±2.6,6.5±2.2 and 4.5±1.6,respectively.The histopathological score of arginine 7 d group was significantly lower than those in arginine 24 h group (P ＜ 0.05 ).Obvious collagen could be found in pancreatic parenchyma in arginine 7 d group,while little collagen was found in pancreatic tissue in control,arginine 12 h and arginine 24 h groups.Conclusions Injection of L-arglnine induced fibrosis in pancreatic parenchyma and proliferation of tubular complex 7 days later,and it could be used for chronic pancreatitis model induction.
