1.Expression and correlation of Cx43 and E-cad in esophageal carcinoma
Chinese Journal of Clinical and Experimental Pathology 2015;(10):1099-1101,1106
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.
2.Preparation of lentivirus silencing SND1 and its influence on breast cancer cell proliferation and invasion
Chinese Journal of Clinical Oncology 2013;(13):749-753
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.

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.

Objective:To analyze the job preference of doctors at township health center ( THC) and provide references for formulating effective policy. Methods:238 cases of doctors were sampled from Shandong, Anhui and Shaanxi provinces. Using a discrete choice experiment, we analyzed the data with a conditional logit model. Results:The most important job attribution was salary, followed by education for children, permanent post, work location, training opportunity, and years before promotion. The OR value of the monthly income of 8 000 yuan is 7. 0 compared to 2 000 yuan. Doctors will pay 3 857 yuan and 3 294 yuan respectively for better education for children and perma-nent posts. Monthly income increasing to 8 000 yuan will reduce the quitting rate from 35% to 8%, and providing better education for children and permanent posts will reduce 5%. The permanent posts at township health center and non-permanent posts in county hospital have the same appeal to the doctor. Conclusion:When choosing a job, doc-tors at THCs valued salary the most. Improving the education level for children can be beneficial for attracting and re-taining doctors at THCs. A permanent post is more attractive to doctors than non-permanent posts at THCs.

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.

Objective To investigate the antigenicity of foreign antigen in recombinant vaccinia virus (VACV) after elimination of B8R,and provide help to improve the efficacy of VACV-based vaccines,and provide guidance for vaccine design.Methods Transfer vector pSC11-OVA was generated,and OVAgene was in,rted into VACV with B8R deletion.The biological characteristics of recombinant VACV was investigated in vitro,and the immune responses against OVA were tested in vivo.Results The plague phenotypes and growth of wcombinant VACV and its parental strains were essentially identical.Cellular immuneresponse against OVA was augmented in mice infected with B8R-deleted recombinant VACV when comparedwith those infected with B8R-intact recombinant VACV.Conclusion Deletion of B8R and insertion of OVAdoes not affect the biological characteristics of VACV.Immunogenicity of exogenous target antigens can beimproved in VACV with B8R deficiency.Deletion of dominant epitopes may provide a vector with more efficiency for vaccines and gene therapy.
