Purpose To investigate the expression of the Cx43 and E-cad protein in esophageal carcinoma and normal esophageal tis-sue and to discuss their relationship. Methods SP immunohistochemical and Western blot analysis were used to detect the expression of Cx43 and E-cad in esophageal carcinoma and normal esophageal tissue. The relation between their expression and esophageal carci-noma was investigated. Results Immunohistochemical assay and Western blot analysis showed the expression levels of Cx43 and E-cad in esophageal carcinoma were significantly lower than that in normal esophageal tissue. The expression of Cx43 had correlation with lymph node metastasis. The expression of E-cad had correlation with degrees of pathological differentiation. There was a positive rela-tionship between the expression of Cx43 and E-cad in same sample. Conclusion Expression of Cx43 and E-cad protein is low in e-sophageal carcinoma, which can be helpful in the prediction of the biological behavior and prognosis of esophageal carcinoma.

Objective: This work aimed to construct stable MCF-7 cell sublines from which staphylococcal nuclease domain con-taining 1 (SND1) expression was interfered to analyze the effect of SND1 silencing on the proliferation and metastasis of MCF-7 cells. Methods: The lentivirus that could mediate SND1 silencing was prepared. MCF-7 cells were infected with the lentiviruses to construct stable sub-cell lines. Quantitative real-time polymerase chain reaction and Western blot analysis were employed to determine SND1 ex-pression level. MTS, wound healing, and transwell assays were applied to analyze the effect of SND1 silencing on the proliferation, mi-gration, and invasion of MCF-7 cells. Results: A lentivirus expression vector that contains sequences encoding shRNAs targeting SND1 and an shRNA negative control were successfully established. The lentiviruses (LV-SH1, LV-SH2, LV-SH3, and 和 LV-NC) were then collected and packaged. Stabilized MCF-7 sublines were prepared through infection with lentiviruses. The most efficient MCF-7 stable cell subline, MCF-SH3, was selected for SND1 silencing. Compared with the control cell, the proliferation, migration, and inva-sion potential of MCF-SH3 were significantly decreased. Conclusion: SND1 could promote the proliferation, migration, and invasion of breast cancer cells. Thus, silencing SND1 expression will inhibit such proliferation, migration, and invasion. These results indicated that the unusual expression of SND1 is associated with breast cancer and may participate in cancer progression by affecting prolifera-tion, migration, and invasion.

OBJECTIVE:To promote plasma concentration monitoring of anti-tuberculosis agents in the clinic.METHODS:Results of plasma concentration monitoring of rifampicin and isoniazid in tuberculosis patients of our hospital from Aug.2005 to Dec.2008 were analyzed retrospectively.RESULTS:Plasma concentration samples were collected from 241 patients treated with rifampicin and 53 patients treated with isoniazid 2 hours after medication.Plasma concentrations of rifampicin in 10.4% of patients were below the normal level and 31.9% were higher than the normal level.Plasma concentrations of isoniazid in 71.7% of patients were below the normal level and 15.1% were higher than the normal level.CONCLUSION:Plasma concentration monitoring of anti-tuberculosis agents is a valuable tool to adjust the dosage of drugs,which is valuable for rational use of drugs in tuberculosis patients.

International Classification of Functioning, Disability and Health (ICF) is one of core classifications launched by WHO. This paper discussed interactive model of functioning and disability and terminological system based on ICF and approaches of the developments of standardized measurement instruments.

HPLC analysis was performed to study the changes in chemical composition of ginseng extracts prepared from high quality ginseng with 0, 2, 4, 8 h of steamed times. An UFLC-MS/MS multiple-reaction monitoring (MRM) quantitative analysis was made to investigate the pharmacokinetic behavior differences of ginsenosides in mice ig administered of ginseng extracts with different steamed times in the negative ion mode, with Digoxin as the internal standard substance. The mice were injected with LPS to establish inflammation model after ig administration of ginseng for a week and the contents of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in mice plasma were detected by ELISA, in order to study on anti-inflammatory effects of ginseng with different steamed times. It was determined that levels of TNF-α and IL-1β were significantly decreased in inflammation model group ig administered of ginseng extracts with 8h of steamed time. The results showed that the chemical components in ginseng changed after steaming and the components into the blood changed, correspondingly. Ginseng with steamed 8 h contributes to anti-inflammatory effects. These results provided an experimental basis for revealing the active substance basis and dose-effect relationship of ginseng on anti-inflammatory effect.

ObjectiveTo explore the relationship between diet habits and constitution type of 8448adults from 9 provinces and municipalities of China.MethodsA total of 8448 participants from Jiangsu,Anhui,Gansu,Qinghai,Fujian,Beijing,Jilin,Jiangxi and Henan Province were enrolled in this study.The clinical information of constitution type,diet habits and demographic characteristics was collected.Logistic regression analysis was used to evaluate the relationship between diet habits and constitution type.ResultsLogistic regression analysis showed that gentleness type and Qi-deficiency were correlated with sweet food ( OR =1.22,P ＜ 0.05 ). There was a significantly positive correlation between Yangdeficiency and hot food intake ( OR =2.89,P ＜ 0.05 ),as well as between Yin-deficiency and cold food intake ( OR =1.56,P ＜ 0.05).Phlegm-wetness was mainly caused by fatty food consumption ( OR =2.07,P ＜ 0.05 ).Barbecue food was positively correlated with Wet-heat type ( OR =1.64,P ＜ 0.05 ),Bloodstasis type ( OR =1.37,P ＜ 0.05 ),and Qi-depression type ( OR =1.35,P ＜ 0.05 ).Special diathesis type was related to dietary preference of sweet food ( OR =1.29,P ＜ 0.05 ).ConclusionDifferent type of constitution may be related to specific lifestyle or diet habits,and diet habit might play a positive role in Gentleness type or health condition.
