According to traditional Chinese medical theory"Qi in motion can normalize blood circulation". To study the therapeutic effect of herbs regulating Qi on inhibition of tumor metastasis,their influence on blood stasis was investigated. Results showed that the herbs could slow down platelet aggregation and normalize the balance between TXA2 and PGI2. Hence,the herbs could inhibit tumor growth and metastasis.

ObjectiveTo discuss the clinical diagnosis and treatment of multiple endocrine neoplasia ( MEN ) 2A, and report the mutation of the RET proto-oncogene in a pedigree of three patients with MEN 2A.MethodsBilateral adrenalectomy was performed on two of the three patients with hypertension and bilateral adrenal-conserving adrenal pheochromocytoma resection was performed on the other patient. All three patients were treated by total thyroidectomy and neck lymphadenectomy. Twelve family members were recruited to the study. Peripheral blood was collected and total genomic DNA was prepared for polymerase chain reaction (PCR). PCR products of exon 10 and exon 11 of the RET proto-oncogene were purified and a direct DNA sequence analysis was performed.ResultsThe pathological diagnosis of the specimens was bilateral adrenal pheochromocytoma and medullary thyroid carcinoma in all the three patients. There was no tumor recurrence or distant metastasis after 1.5 - 5 years of follow-up. A missense mutation of TGC (Cys)to CGC (Arg) at codon 634 in exon 11 of the RET proto-oncogene was detected in all three patients. Genetic screening identified two mutation carriers in the other members of this pedigree.ConclusionGenetic mutation screening and surgical intervention may be helpful to the members of high-risk families.

Objective:To study the cytokine mechanism of Jiawei Xuanfei Toujie Ji(JXT)therapy to influenza infected mouse.Methods:Mice were inoculated intranasally with mouse lung-adapted influenza virus strain(FM1),and were treated with JXT. At 5th days after postinoculation were sacrificed, and IL-2,TNF-?,IL-6,IFN-? in their sera were measured with ELISA kits, their lungs sections were stained with hematoxylin and eosin.Results:Compared with model group ,the levels of IL-2 and IFN-? in JXT group were dramatically higher,and the levels of TNF-? and IL-6 were lower,and pathological effects of influenza pneumonia showed less lung injury.Conclusion:Regulative effects on cytokine may be one of the factors that JXT decrease the pathogenesis of influenza-induced acute lung injury.

AIM: To study the effect of berberine(Ber) on invasion and migration of PG cells from a high metastatic human giant lung carcinoma cell line and to explore its mechanism. METHODS: Agarose drop method was used to detect PG migration; transwell cabin with FN in lower chamber was adopted to detect PG chemotaxis. PG adhesion to FN and martrigel was detected by MTT; PG invasive ability was determined by transwell cabin covered with martrigel. Expression of MMP2/TIMP2 protein and mRNA were detected by quantitative immunocytochemical method and RT - PCR respectively. RESULTS: After PG was treated by Ber( 10 mg/L) for 24 h: 1 ) migration distance of Ber- treated PG cells was markedly shorter than that of control cells (P <0. 01 ) and the number of passed membrane cells towards FN was much fewer than that of control cells ( P < 0. 01 ); 2) PG adhesion to FN and martrigel was inhibited remarkably by Ber compared with control PG; 3) the migration of PG cells through the martrigel -coated transwell was significantly inhibited by the addition of Ber; 4) MMP2 expression was reduced significantly(P <0. 01 ), while the TIMP2 expression showed up - regulating tendency, but had no differences compared with control group (P > 0. 05). The MMP2/TIMP2 ratio was decreased; 5 )the MMP2 mRNA/TIMP2 mRNA ratio was decreased by Ber. CONCLUSION: Inhibition of cell migration, adhesion to ECM and invasion into ECM of tumor cells and regulation of homeostasis between MMPs and TIMPs to maintain ECM integrity may be the basic mechanism of inhibitive effect of Ber on invasion and metastasis of tumors.

Objective To evaluate the feasibility and accuracy of full volume three-dimensional echocardiography(FV3DE) for quantifying the left ventricular volume in healthy fetuses. Methods Two hundred and twenty-two normal fetuses with gestational ages between 20 and 40 weeks were investigated. Full volume three-dimensional, two-dimensional (2D) and M-mode images were acquired by Philips iE33 system and data was processed offline using QLAB analysis software. Left ventricular end-systolic volume(ESV) and end-diastolic volume ( EDV) were measured using semiautomated border detection echocardiographic techniques, and compared with 2D biplane Simpson's method and M-mode Teichholz formula. Results Thirty-six fetuses with poor three-dimensional images and 5 twin pregnancies were excluded,the study subjects consisted of 181 singleton fetuses. The highest concordance correlation ( r =0.987 for EDV, r =0.988 for ESV) P <0. 001) was noted between 2D biplane Simpson's and FV3DE-derived values with a small bias (0. 332 ml for EDV,0. 135 ml for ESV). The Bland-Altman analysis showed that FV3DE had the best reproducibility than M-mode Teichholz formula and 2D biplane Simpson's method. Intra- and interobserver error of EDV were 2.85% and 4.22% for FV3DE,8.37% and 8.98% for 2D biplane Simpson's rule,30. 63% and 54. 70% for M-mode Teichholz formula. Intra- and interobserver error of ESV were 2.34% and 6. 14% for FV3DE,6. 26% and 11.7% for 2D biplane Simpson's rule,43.06% and 66.03% for M-mode Teichholz formula. Conclusions FV3DE is a novel technique that can be more accurate than conventional methods in quantification of fetal left ventricular volumes, it may provide new insight into evolving fetal cardiac structure and function.

Objective To retrospectively analyze the relationship between progression free survival (PFS) and overall survival (OS) in patients with non small cell lung cancer (NSCLC), and to detect the influence of plasma fibrinogen and D-dimer levels before treatment in the prognosis of advanced stage (stageⅢB-Ⅳ) of NSCLC. Methods The study comprised 134 NSCLC patients with clear pathological diagnosis. All patients were grouped by plasma fibrinogen and D-dimer levels before treatment. We set the normal values of fibrinogen as≤4 g/L and D-dimer as≤500μg/L(FEU). Patients with normal levels of fibrinogen and D-dimer were grouped into low risk group, patients with elevated fibrinogen or D-dimer were grouped into median risk group, and patients with both elevated values were grouped into high risk group. Chi-square test and one way ANOVA analysis were used to analyze the clinicopathologic features of different groups. The OS and PFS in different groups were analyzed by Kaplan-Meier analysis. Univariate analysis of PFS and OS were conducted. Then multivariate analysis was conducted with the Cox regression model in three groups. Results The clinicopathologic features showed no differences between different groups. There were significant differences in OS and PFS between high risk group and other groups. In the survival curves, the high risk group showed poor prognosis. The result of multivariate analysis showed that clinical stage (OS:RR=1.846, 95%CI 1.150-2.964,P=0.011; PFS:RR=1.762, 95%CI 1.190-2.609, P=0.005) and grouped by fibrinogen and D-dimer (OS:RR=1.415,95%CI 1.050-1.908,P=0.023;PFS:RR=1.373,95%CI 1.070-1.761,P=0.013) were prognostic factors for patients with NSCLC. Conclusion The plasma fibrinogen and D-dimer levels before treatment are closely related with the prognosis of NSCLC patients. And a high plasma fibrinogen and D-dimer levels before treatment are associated with poor prognosis in advanced stage of NSCLC patients.

AIM:To study the effect of Yiqi Huoxue Jiedu Fang(YHJ),composed of ginsenoside,penex notogingseng and berberin,on tumor growth and metastasis and to explore its mechanism.METHODS:Murine Lewis lung carcinoma transplant model was established and mice were treated with YHJ by intraperitoneal injection.After 10 days,the inhibitory rate of tumor,pathology of tumor and PCNA of tumor cells were detected.After 20 days,numbers of metastatic foci on lung surface and microvessel density(MVD)were determined.Expression of VEGF in tumor and serum were also analyzed by immunohistochemical test and ELISA,respectively.RESULTS:YHJ reduced the weight of tumor and the amount of metastatic foci.The inhibitory rates of tumor at high and low dose of YHJ(24 mg?kg-1?d-1,12 mg?kg-1?d-1)were 48.29% and 37.26%,and the number of metastatic foci was 1.67 and 3.50,while control was 6.44.Furthermore,PCNA of tumor cells,MVD of tumor and VEGF expression in serum and tumor were decreased in YHJ treatment goup as compared with control.CONCLUSION:YHJ remarkably inhibits Lewis lung carcinoma growth and metastasis in mice.Its mechanism may be related to inhibition of angiogenesis.
