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.

OBJECTIVESTo explore whether the angiotensin I -converting enzyme (ACE) I/D (insertion/ deletion) polymorphism is associated with the susceptibility to high altitude pulmonary edema (HAPE) in the Han Chinese.
METHODSOne hundred and forty-seven HAPE-p (HAPE patients) and 193 HAPE-r (HAPE resistants) were enrolled from the Yushu earthquake reconstruction workers in Qinghai province where the altitude is over 3 500 m above sea level. Blood samples were collected from each of the HAPE-p and HAPE-r groups. Information about physiological phenotypes was obtained via fieldwork investigation. The ACE-I/D polymorphism in HAPE-p and HAPE-r was detected by polymerase chain reaction (PCR).
RESULTSThe SaO2 was significantly lower while HR was significantly higher in HAPE-p group than those in HAPE-r group. The genotype frequencies of ACE-I/D for II, ID, DD in HAPE-r and HAPE-p groups were 0.430, 0.446, 0.124 and 0.435, 0.469, 0.095, respectively, the allelic frequencies of I and D were 0.650, 0.350 and 0.670, 0.330, respectively. The OR of ID, DD and D alleles relative to II for HAPE was 0.961 (0.610-1.514), 1.322 (0.634-2.758) and 1.080 (0.783-1.489). There was no significant difference of the genotypic and the allelic frequencies in ACE-I/D polymorphism between HAPE-p and HAPE-r groups.
CONCLUSIONSThere is no relation between ACE-I/D polymorphism and HAPE in the Han Chinese.

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.
