Chinese Journal of Information on Traditional Chinese Medicine 2014;(6):33-34,37
Objective To discuss the features and general patterns of adverse drug reaction (ADR) of Xiangdan injection, and provide reference for clinical safe medication. Methods The author retrieved 73 cases about ADR of Xiangdan injection in domestic medicine journals from 2002 to 2012, collected and analyzed the information about patients’ general conditions, medicine dosage and solvent, ADR happening time, clinical manifestations, and prognosis. Results The main clinical manifestation of ADR was anaphylactic shock, with the incidence rate of 46.58%(34/73), and the happening time was mainly within 30 minutes after the patients received Xiangdan injection (46/73, 63.01%). Conclusion TCM injection should be used properly. At the same time, clinical medication monitoring should be strengthened, with a purpose to reduce and avoid ADR of Xiangdan injection.

Objective To explore the mechanism of immune tolerance in chronic B hepatitis, the effects of HBV infection on the functions of macrophages and related mechanism of signal transduction by transfection in vitro were studied. Methods Peritoneal macrophages of mice were isolated regularly and cultured, transfected transiently with pcDNA3-HBV or pcDNA3 plasmid DNA and cultured under the stimulation of LPS. After 72 h, RT-PCR was performed to detect the expression of PreS1, TNF-? or IL-1? mRNA. To detect the expression of NF-?B RelA protein by FCM, and the level of nitric oxide in cultural supernatant was measured with Griess reaction. Results After being transfected with pcDNA3-HBV,peritoneal macrophages had the expression of PreS1 mRNA, but have lower level of TNF-?、IL-1? mRNA and transcriptional factor NF-?B, compared with pcDNA3-transfected control group; the level of nitric oxide in pcDNA3-HBV group was also decreased. Conclusions Transient transfection of pcDNA3-HBV could decrease the function of macrophages directly by inhibiting NF-?B activity and effector molecules production, which may be one of the mechanisms of immune tolerance in chronic B hepatitis.

It had been proved by many evidences that several heat shock proteins (HSPs) expression is up-regulated in tissue-derived primary lung cancer, and HSPs may play important roles in development, in resistant to drugs and in prognosis of lung cancer. However, there have not still systemic research on which HSPs,especially HSP70 can be or not thought as a new biological target in the therapy to lung cancer. In order to address the expression and roles of heat shock protein 70 (HSP70) in lung adenocarcinoma, immunoblotting was performed to detect the expression of HSP70 in tissue specimens from lung adenocarcinoma which were diagnosed unambiguously by branch fibromicroscopy and were excised. It showed that in the normal lung tissues, the expression of HSP70 was less then that in cancer tissues. After down-regulation of HSP70 protein by HSP70 anti-sense oligonucleotides in A549 cell line, MTT assay showed that the proliferation of A549 cells was inhibited remarkably after the treatment with HSP70 antisense oligonucleotides and Act D. There had significant differential in HSP70 antisense treatment group followed by Act D treatment and Act D treatment group. Results of Hoechst33258 staining revealed that HSP70 antisense oligonucleotides could promote Act D-mediated apoptosis in A549 cells with a higher percentage of apoptotic cells (26.91?3.73)% than that of Act D-treated group (16.83?3.41)% (P

Objective:To investigate the mRNA expression of the WIF-1 gene and the methylation of its promoter in breast can-cer, and to determine the correlation between the epigenetic aberrant WIF-1 DNA methylation and the clinicopathological significance of WIF-1 in breast cancer . Methods:RT-PCR and sensitive methylation-specific-PCR (MSP) were used to detect WIF-1 mRNA ex-pression and the methylation of the WIF-1 promoter in 30 breast cancer samples as well as in tumor-adjacent tissue samples and 9 be-nign breast tissues. Results:The WIF-1 mRNA expression in 30 breast cancer samples significantly decreased compared with those of the other two groups. In addition, WIF-1 methylation was more frequent in breast-tumor tissues compared with those in tumor-free tis-sues. Meanwhile, WIF-1 mRNA expression in breast cancer tissues involved the abnormal methylation of its promoter. Clinicopatholog-ical correlation analysis showed that the abnormal methylation of the WIF-1 gene promoter was not associated with age, TNM stage, histotype, or lymph node metastasis. Conclusion:WIF-1 mRNA expression loss due to abnormal methylation may be a crucial factor in breast cancer development and can thus be used in the prognosis and progression of the disease.
