ABSTRACT
Epithelial-mesenchymal transition (EMT) is a complex transformation process and plays an important role in the invasion of cancer cells. The morphological transformation in cancer cells are accompanied by various cellular processes such as alterations in cell adhesion, cell matrix degradation, changes in epithelial markers and mesenchymal markers. Mucin (MUC) is widely distributed in epithelial cells of various tissues and organs and plays an important role in EMT. Meanwhile, MUC also can mediate signal transduction and cell adhesion, participate in tumor invasion and metastasis. This article reviewed the advances in research on EMT and MUC in tumors.
ABSTRACT
Objective:To analyze the efficacy and safety of targeted drug apatinib combined with tegafur, gimeracil and oteracil capsules (TS-1) in the second-line treatment of advanced gastric mucinous adenocarcinoma. Methods: Totally 48 patients with ad-vanced gastric mucinous adenocarcinoma treated with the second-line regimen were randomly divided into the control group and the treatment group with 24 ones in each. The control group received the chemotherapy of TS-1, and the treatment group received apatinib additionally. The adverse reactions and objective effects were observed. Results:The objective response rate (ORR) was 54. 1% and 33. 3% in the treatment and the control group, respectively. The disease control rate (DCR) was 83. 3% and 54. 2% in the treatment and the control group, respectively. There were significant differences on ORR and DCR in both groups(P<0. 05), while no statisti-cal difference was shown in the adverse reactions (P>0. 05) between the two groups. Conclusion:Apatinib combined with TS-1 ex-hibits evident short-term therapeutic effect on advanced gastric mucinous adenocarcinoma, and the adverse reactions can be tolerated.

ABSTRACT
To understand the use in recent 10 years of(GB/T 12346-2006),a standard of The People's Republic of China,so as to provide the evidence for its further establishment and revision,we investigated and analyzed the application ofthrough relevant literature and the textbook. It is found that making use of the standard is being realized in various types of articles and it is described in almost all the textbooks. Implementing the standard intensively promotes the standardization of acupuncture-moxibustion education and clinical manipulation as well as the academic exchange domestically and overseas. In turn,its scientificalness and authority are further strengthened.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the correlation between propagated sensation along meridian (PSM) and TCM constitution at different age stages.</p><p><b>METHODS</b>According to age, 840 participants were divided into a youth group (326 cases), a middle aged group (243 cases) and an elderly group (271 cases). The TCM constitution of all the participants was evaluated, and the PSM test was performed. The distribution of TCM constitution, the occurring rate and transmission of PSM in each group were observed and compared; the correlation between PSM and the TCM constitution was preliminary investigated by Logistic regression analysis.</p><p><b>RESULTS</b>The distribution of nine types of TCM constitution in three groups:the proportion of normal constitution and partial constitution were significantly different (all<0.05); the occurring rate and transmission of PSM in three groups were not significantly different (all>0.05); the proportion of occurring rate for nine types of TCM constitutions in the whole population, from high to low, presented special intrinsic quality, neutral quality,-deficiency quality,-deficiency quality,-deficiency quality, damp-heat quality, phlegm-dampness quality,-stagnation quality and blood-stasis quality; besides, the proportion of occurring rate for different TCM constitutions in the youth group, middle aged group and elderly group was similar to that of whole population. The Logistic regression analysis results indicated the neutral quality (=0.025) and special intrinsic quality (=0.018) were positively while blood-stasis quality (=0.043) was negatively related with PSM in all subjects; the-deficiency quality (=0.025), phlegm-dampness quality (=0.019), blood-stasis quality (=0.012) and-stagnation quality (=0.035) were negatively related with PSM in youth group; the neutral quality (=0.001) was positively related with PSM inthe middle aged group; the neutral quality (=0.006) anddeficiency quality (=0.004) were positively related with PSM in the elderly group.</p><p><b>CONCLUSIONS</b>The occurrence of PSM in different age stages is related with TCM constitution, which could be increased in clinical treatment to improve acupuncture efficacy.</p>
ABSTRACT
Twenty-two items of national criteria of acupuncture-moxibustion operation standardization have been issued by the People’s Republic of China. To understand the situation of use of these criteria, the authors analyzed and studied the situation of application of acupuncture-moxibustion criteria in related papers, textbooks and monographs to provide a basis for further establishing and revising the criteria. The results show that people are building awareness of use of acupuncture-moxibustion criteria, and the criteria have gradually been used in more and more papers, textbooks and works.
ABSTRACT
Objective To explore the role of Kupffer cells( KCs)disorder on the occurrence and development of Nonalcoholic Fatty Liver Disease ( NAFLD) by means of rat model fed with high-fat diet. Methods Twenty-four male SD rats were random divided into model group ( n =12) and normal group( n = 12) , with a high-fat diet and standard diet for 12 weeks. The levels of body weight, liver weight, alanine aminotransferase( ALT), aspartate aminotransferase( AST) , triglyceride(TG) , and total cholesterol( TC) were measured. Routine histological features of hepatic section were observed by H. E staining. The shape changes of KCs in the liver were detected, and the levels of tumor necrosis factor-α(TNF-α) and nitric oxide (NO) secreted by KCs were measured. Results The weight, liver index, the levels of ALT, AST, TG, TC, and the levels of TNF-α and NO secreted by KCs in model group were higher than that in the normal group ( P < 0. 05). Histopathological examination showed hepatocellular macrovesicular steatosis, lobular inflammatory cell infiltration and necrosis. Compared with normal group, the shape and function of KCs in the liver changed largely. Furthermore, these changes of KCs were in accordance with the degree of steatosis, inflammation and necrosis in the liver of the model group. Conclusions The shape and function of KCs changed significantly in NAFLD induced by high-fat diet, and KCs disorder might be involved in the pathogenesis of NAFLD.
ABSTRACT
Objective:To find the threshold value concentration of cobalt causing myocardium cell damage.Methods:Cobalt in different concentrations (10 μg/ml,20 μg/ml,40 μg/ml,80 μg/ml) were added into the medium of cultured myocardium cell of rat (1～3 days old) in vitro.Then the activities of GOT,CK,LDH,HBDH in the medium were measured.Results:The results showed that when cobalt concentration was 10～20 μg/ml,the activity of GOT,CK,LDH,HBDH did not change markedly.But when cobalt concentration was more than 40 μg/ml,the activities of those enzymes increased significantly.Conclusion:The studies demonstrated that the activities of enzymes in the medium of cultured myocardium cell could increase with the difference of coblat concentrations.The threshold value concentration of cobalt which could cause myocardium cell damage is 40 μg/ml.
