BACKGROUND:The metastatic potential of hepatocelular carcinoma cels is key factor influencing patient’s prognosis. To observe the effect of human bone marrow mesenchymal stem cels on metastasis of hepatocelular carcinoma is of great significance for improving the lifetime of hepatocelular carcinoma patients. OBJECTIVE:To explore the biological effect of human bone marrow mesenchymal stem cels on hepatocelular carcinoma cels with different metastatic potentials. METHODS:Human bone marrow mesenchymal stem cels and hepatocelular carcinoma cel suspension with high and low metastatic potentials were respectively injected into the Transwel chamber, and after 36 hours of co-culture, ELISA method was used to detect the absorbance value as wel as cel counting method was used to observe the changes in the invasion ability of hepatocelular carcinoma cels. The effects of human bone marrow mesenchymal stem cels on the proliferation of hepatocelular carcinoma cel suspension with high and low metastatic potentials were determined using cel counting kit-8. PCR method was adopted to measure the expression of osteopontin, bone specific sialoproteins, integration (alpha V), transforming growth factor beta 1 and programmed cel death protein 5. RESULTS AND CONCLUSION:(1) The number of migrated hepatocelular carcinoma cels was significantly lower in the co-culture group than the single culture group, and based on the semi-quantitative detection of invasion ability, the absorbance value of the co-culture group was significantly lower than that in the single culture group (P < 0.05). (2) The expression of osteopontin and bone specific sialoproteins was significantly decreased in the co-culture group with high metastatic potential (P < 0.05), but there was no change in the expression of integration (alpha V) (P> 0.05). In the co-culture group with low metastatic potential, the expression of osteopontin, bone specific sialoproteins, and integration (alpha V) were declined remarkably (P < 0.05). (3) Results from the semi-quantitative detection of proliferation ability showed that the absorbance value of the co-culture group was significantly higher than that of the single culture group (P < 0.05). (4) In the co-culture group with high metastatic potential, the expression of transforming growth factor beta 1 was up-regulated significantly (P< 0.05), but the expression of programmed cel death protein 5 showed no changes (P > 0.05). However, in the co-culture group with low metastatic potential, the expression of transforming growth factor beta 1 and programmed cel death protein 5 was both increased dramaticaly (P < 0.05). These findings suggest that the human bone marrow mesenchymal stem cels reduce the invasion ability of hepatocelular carcinoma cels, and enhance their ability of proliferation.

OBJECTIVETo provide evidence for Chinese medical treatment of children with EB virus infection by exploring its clinical efficacy from multiple angles.

METHODSTotally 81 children patients were randomly assigned to the treatment group (46 cases) and the control group (35 cases). Patients in the treatment group took Chinese medical decoction, while those in the control received intravenous dripping of Ganciclovir and oral administration of pidotimod. The treatment period for the two groups was 2 weeks. Patients were followed-up till the 12th week. Clinical symptoms such as fever, lymphadenopathy and hepatosplenomegaly, as well as lab indices such as abnormal lymphocyte percentage, EB virus antibody, virus DNA load, T cell subsets, immunoglobulin, and so on were observed before and after treatment, at week 4 and 12 of follow-ups.

RESULTS(1) The total effective rate at week 2 was 95.6% in the treatment group, higher than that of the control group (94.3%), but there was no statistical difference between the two groups. (2) The time for defervescence, duration of pharyngeal hyperemia, duration of swollen tonsils was shorter in the treatment group than in the control group (P<0.05). The subsidence of lymphadenopathy, hepatomegaly, and abnormal lymphocytes was better in the treatment group than in the control group (P < 0.05). (3) The positive cases of peripheral blood hetero-lymphocyte was significantly reduced after treatment, at week 4 and 12 of follow-ups both in the treatment group and the control group (P < 0.01). The expression of IgA and IgM decreased after treatment in the two groups when compared with before treatment in the same group (P < 0.05, P < 0.01). IgG in the treatment group also obviously decreased after treatment, at week 4 and 12 of follow-ups (P < 0.05, P < 0.01), while it decreased only after treatment in the control group (P < 0.05). Activities of AST and ALT in the treatment group and the AST activity in the control group were markedly improved when compared with those before treatment (P < 0.05). Compared with the control group, the abnormal lymphocyte positive case number obviously decreased in the treatment group after treatment, at week 4 and 12 of follow-ups (P < 0.05). (4) After treatment, at week 4 and 12 of follow-ups, CD3+ and CD8+ significantly decreased; CD4+, CD4/CD8, and B cells significantly increased in the two groups, when compared with before treatment (P < 0.05). NK cells significantly increased more in the treatment group after treatment, at week 4 and 12 of follow-ups, higher than before treatment as well as the control group (P < 0.05). (5) EB viral DNA and EB viral CA-IgM negative conversion case numbers significantly increased in the two groups after treatment, at week 4 and 12 of follow-ups (P < 0.05). Compared with the control group, EB viral DNA and EB viral CA-IgM negative conversion case numbers significantly increased in the treatment group after treatment and at week 4 of follow-ups (P < 0.05).

CONCLUSIONSTreatment of EB virus infection by Chinese medical treatment was effective. It could promote the recovery of EB viral infection, and reduce the risk of vicious disease after EB viral infection.

It was reported that a complete antifertility action of alpha-chlorohydrin in combination with glycidol in male rats after a daily oral dose of 5mg/kg and 75mg/kg respectively for two days. Simultaneously some ultrastructural changes including mitochondrial swelling, atrophy of Golgi complex, decreasing in pinocytotic vesicles and stereocilia were found in principal cells of epididymis within 3 days after medication.In this experiment the animals received 3, 6 and 9 courses of treatment respectively, each course included two days of administration with a daily dose mentioned above and eight days of cessation of medication.The specimens of initial segment of epididymis, liver and kidney were taken at the end of 3 rd, 6 th and 9th courses of treatment for electron microscopy.The principal cells of initial segment of epididymis revealed a normal feature at the end of 3 rd and 9 th course of treatment. But at the end of 6 th course of treatment, the atrophy of Golgi complex and the decrease in stereocilia and pinocytotic vesicles were found in some principal cells.Any ultrastructural changs of sperms in the initial segment were not found by electron microscope.There was also mitochondrial changes with striking increase in the density of the matrix and reduction of size in some liver cells at the end of 6 th course of treatment, but not at the end of 3 rd or 9 th course of treatment. The epithelial cells of nephron in all the specimens revealed a normal ultrastructural feature.The results suggest that the ultrastructural changes of the principal cells and the liver cells induced by the mixture of the drugs could be recovered at the end of treatments.
