The serumlevels of hyaluronic acid (HA), procollagen Ⅲ (PC-Ⅲ), Ⅳ collagen (Ⅳ-C) and Laminin (LN) of thepatients were determined, compared and analyzed before treatment and after 3-month treatment in the twogroups. The results showed that in the treatment group, the levels of HA, PC-Ⅲ, Ⅳ-C and LN after3-month treatment were significantly lowered as compared to that before treatment (P<0.01). In thecontrol group, only the HA level was obviously lowered (P<0.05). There was an significant difference(P<0.05) in PC-Ⅲ and Ⅳ-C and a very significant difference (P<0.01) in HA after treatment between thetwo groups. It is therefore concluded that Da Ding Feng Zhu Decoction can lower serum indexes of liverfibrosis.展开更多

Although scholars disagreed about the effect of AD on infertility, more and more evidence showed that AD was closely related to the str uct ural and func ti onal defects of the eutopic endomet rium and myomet rial junc tional zone (MJZ), which may lead to embryo implantation failure and infertility. With the rapid development of imaging technology, the accuracy of diagnose AD has been enhanced, more and more infertility patients were diagnosed with AD. At the same time, a series of pathogenic hypothesis have been proposed to explain the relationship between AD. In addition, AD may influence the patient's reproductive function by affecting sperm transport, embryo implantation, altering uterine peristalsis, influencing the structure and function of endometrium, and changing the intrauterine environment. At present, the treatment of AD-associated infertility is similar to the treatment of AD. The commonly used treatment methods include drug therapy, conservative operative treatment, drug combination surgery, and Chinese medicine treatment and so on. The clinical and experimental studies of AD complicated with infertility and its possible pathogenesis and treatment in recent years are reviewed in this article.展开更多

Methods: A total of 128 UC patients who received treatment in the hospital between January 2013 and April 2017 were collected and divided into control group and observation group by random number table. Control group received conventional oral drug therapy, and the observation group received retention enema by caulis sargentodoxae enema combined with oral drug therapy. Before treatment and after 4 weeks of treatment, the differences in the levels of immunoglobulin and inflammatory response indexes in serum as well as intestinal flora levels in mucosa lesion tissue were compared between the two groups.Results: The differences in levels of immunoglobulin and inflammatory response indexes in serum as well as intestinal flora levels in mucosa lesion tissue were not statistically significant between the two groups of patients before treatment. After 4 weeks of treatment, IgA, IgG, IgM and IL-4 contents in serum as well as bifidobacterium and lactobacillus levels in mucosa lesion tissue of observation group were higher than those of control group while ESR, CRP, IL-6 and TNF-αcontents as well as E. coli level in mucosa lesion tissue were lower than those of control group. Conclusion: Retention enema by caulis sargentodoxae enema combined with oral drugs can effectively optimize the immune inflammatory state and balance the intestinal flora distribution in patients with UC.展开更多

Autophagy plays dual roles in the survival and death of cancer cells. Therefore, we investigated the exact role of autophagy in As2O3-induced apoptosis in liver cancer cells.Methods: The viability of hepatoma cells was determined using the MTT assay with or without fetal bovine serum. The rate of apoptosis in liver cancer cells treated with As2O3was evaluated using flow cytometry, Hoechst 33258 staining, and TUNEL assays. The rate of autophagy among liver cancer cells treated with As2O3was detected using immunofluorescence, Western blot assay and transmission electron microscopy.Results: Upon treatment with As2O3, the viability of HepG2 and SMMC-7721 cells was decreased in a time-and dose-dependent manner. The apoptosis rates of both liver cancer cell lines increased with the concentration of As2O3, as shown by flow cytometry. Apoptosis in liver cancer cells treated with As2O3was also shown by the activation of the caspase cascade and the regulation of Bcl-2/Bax expression.Furthermore, As2O3treatment induced autophagy in liver cancer cells;this finding was supported by Western blot, immunofluorescence of LC3-II and beclin 1, and transmission electron microscopy. In liver cancer cells, As2O3inhibited the phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin(PI3K/AKT/mTOR) signal pathway that plays a vital role in both apoptosis and autophagy. The PI3K activator SC-79 partially reversed As2O3-induced autophagy and apoptosis. Furthermore, inhibiting autophagy with 3-methyladenine partially reversed the negative effects of As2O3on cell viability.Serum starvation increased autophagy and amplified the effect of As2O3on cell death.Conclusion: As2O3induces apoptosis and autophagy in liver cancer cells. Autophagy induced by As2O3may have a proapoptotic effect that helps to reduce the viability of liver cancer cells. This study provides novel insights into the effects of As2O3against liver cancer.展开更多

Metabolomics is the scientific study of dynamic chemical processes involving metabolites as well as metabolic response of living organisms. Metabolomics, a research method with integrity and dynamics, corresponds to the overall regulatory effect of acupuncture and is in line with the overall concept of traditional Chinese medicine(TCM) and the concept of homeostasis. In the recent years, metabolomics has been extensively applied to the clinical and experimental study of IBD, and its potential applied value has been unanimously acknowledged by the researchers. In this article, the application status of metabolomics in acupuncture is summarized, and the research ideas to study the mechanism of acupuncture in the regulation and control of IBD by metabolomics are preliminarily explored.展开更多
