Objective To investigate the situations of close contacting with MDR-TB in family and analysis the necessity and urgency of family protection.Methods Nine typical primary MDR-TB cases in our hospital that close contacted with family pulmonary TB patients.their relatives contacted with them and their treatment prognosis were retrospectively analyzed.Results All of the 9 cases were transmitted by lineal MDR-TB relatives.In one case,3 generations were pumonary TB patients.All of 4 family members were pulmonary TBpatients in another case.3 cases were treated with operations:2 cases with pulmonary lobectomy and 1 case with intestinal resection.Treatment prognosis:3 cases cured,2 cases not cured,4 cases dead.Conclusions Family close contacting with MDR-TB patients should be intervened earlier:including health education,effective protection and health examination regularly et al.

OBJECTIVETo investigate the effect of SIRT6/NF-κB signal axis in delaying hematopoietic stem/progenitor cell senescence with ginsenoside Rg1, in order to provide theatrical and experimental basis for looking for methods for delaying HSC senescence.

METHODSca-1 + HSC/HPC was isolated by magnetic cell sorting (MACS) and divided into five groups: the normal control group, the aging group, the positive control group, the Rg1 anti-senescence group, and the Rg1-treated group. Senescence-associated β-galactosidase (SA-β-Gal) staining, cell cycle analysis and hemopoietic progenitor cell mix (CFU-Mix) were adopted to determine the effect Rg1 in delaying or treating Sca-1 + HSC/HPC senescence biology. The mRNA and protein of senescence regulation molecules SIRT6 and NF-KB were examined by realtime fluorescence quantitative PCR (FQ-PCR) and western blotting.

RESULTCompared with the senescence group, the Rg1 anti-senescence group and the Rg1-treated group showed lower percentage in SA-β-Gal-stained positive cells, decreased cell proportion in G1 phase, increased number of CFU-Mix, up-regulated in SIRT6 mRNA and protein expression, down-regulation in NF-KB mRNA and protein expression. The Rg1 anti-senescence group showed more evident changes in indexes than the Rg1-treated group.

CONCLUSIONRg, may inhibit Sca-1 + HSC/HPC senescence induced by t-BHP by regulating SIRT6/NF-KB signal path.

Coptidis Rhizoma-Euodiae Fructus has been widely used for the treatment of digestive diseases since Song Dynasty, and therapeutic efficacy is very obvious. Modern research found that alkaloids are the main bio-active constituents, and some of their contents have striking difference after compatibility of the two herbs. The Chinese medicine pair (CMP) has extensive biological activities, such as the effect of gastrointestinal effect, anti-tumor, lowering the blood pressure and blood fat and so on. And some action mechanism of CMP also got partial demonstration. This paper mainly summarized the bio-active constituents, compatibility effects, action mechanism and clinical applications of the CMP, which can provide a basis for further research and development of the CMP.

OBJECTIVETo observe the effect of American Ginseng Capsule (AGC) on the liver oxidative injury and the Nrf2 protein expression in the liver tissue of rats exposed by 900 MHz cell phone electromagnetic radiation.

METHODSTotally 40 male SD rats were randomly divided into the normal control group, the model group, the Shuifei Jibin Capsule (SJC) group, and the AGC group,10 in each group. Rats in the normal control group were not irradiated. Rats in the rest three groups were exposed by imitated 900 MHz cellular phone for 4 h in 12 consecutive days. Meanwhile, rats in the SJC group and the AGC group were intragastrically administrated with suspension of SJC and AGC (1 mL/200 g body weight) respectively. Normal saline was administered to rats in the normal control group and the model group. The histolomorphological changes of the liver tissue were observed by HE staining. Contents of malonic dialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH), and glutathione peroxidase (GSH-PX)were detected by colorimetry. The Nrf2 protein expression of hepatocytes was detected by immunohistochemical assay and Western blot.

RESULTSCompared with the normal control group, hepatocyte nucleus was atrophied or partially disappeared, the contents of liver MDA and Nrf2 protein obviously increased (P <0. 05, P <0. 01); contents of liver SOD and GSH decreased (P <0. 05) in the model group. Compared with the model group, karyopyknosis was obviously attenuated and approached to the normal level in the SJC group and the AGC group. The contents of liver MDA and Nrf2 protein expression decreased (P <0. 05), and the contents of liver SOD, GSH, and GSH-PX obviously increased (P < 0.05) in the SJC group. The contents of liver MDA and the Nrf2 protein expression decreased (P < 0.05), and contents of SOD and GSH obviously increased in the AGC group (P <0.01, P <0.05).

CONCLUSIONSThe electromagnetic radiation induced by 900 MHz cell phone could affect the expression of Nrf2 protein, induce oxidative injury, and induce abnormal morphology of liver cells. SJC and AGC could promote the morphological recovery of the liver cells. Its mechanism might be related to affecting the expression of Nrf2 protein and attenuating oxidative damage of liver cells.
