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.

Objective To study the effect of selenium on peripheral and splentic T-cell subset, apoptosis of spleen cells in fluorosis chicken and its mechanism. Methods One hundred and eighty 8-day Hailanhe chicks were randomly divided into 3 groups(each 60): ①control group: 195 mg/kg fluoride and 0.08 mg/kg of selenium; ②fluorine group : 1000 mg/kg fluoride and 0.08 mg/kg of selenium ;③selenium antagonism group : 1000 mg/kg On 30~(th), 60~(th), 90~(th) day, peripheral and splentic CD4~+, CD8~+ T-cell subset analyses underwent flow cytometry and apoptosis of spleen cells were detected by TUNEL for study subjects. Results Compared with control group, the CD4~+ T-cell subset of peripheral in fluorine group was decreased obviously in 30,60,90 days[ (35.36± 4.27)% vs (24.29 ± 2.96)%, (47.65 ± 5.42)% vs (41.62 ± 3.96)%, (49.58 ± 3.98) % vs (42.35 ± 6.03 )%, P < 0.05 or < 0.01 ], CD4~+/CD8~+ ratio also was decreased obviously [ ( 1.701 ± 0.145 )% vs (1.393 ± 0.163)%,(2.712 ± 0.345)% vs (1.781 ± 0.201)%,(2.438 ± 0.356)% vs (1.973 ± 0.229)%, P< 0.05 or < 0.01]. Compared with fluorine group, the CD4~+ T-cell subset of peripheral in selenium antagonism group [ (29.40 ± 3.38)%, (45.40 ± 6.01 )%, (46.85 ± 5.25)%, P < 0.05 or < 0.01 ] was increased obviously in 30,60,90 days,CD4~+/CD8~+ ratio in 60,90 days[(2.004 ±0.314)%,(2.211±0.229)%,all P<0.01]also was increased obviously.Compared with control group,the CD4~+ T-cell subset of spleen cells in fluorine group was decreased obviously in 30,60,90 days[(47.33±5.35)% vs(41.91±4.83)%,(49.28±5.24)% vs(41.26 ±4.56)%,(34.31±4.15)%vs(29.33±2.89)%,all P<0.01],CD4~+/CD8~+ ratio also was decreased obviously[(1.927 ±0.244)% vs(1.525 ±0.265)%,(1.847±0.224)% vs(1.640±0.198)%.(1.265±0.174)% vs(0.878±0.092)%,P<0.05 or<0.01].Compared with fluorine group,the CD4~+ T-cell subset of spleen cells in selenium antagonism group in 60,90 days[(44.87±5.43)%,(32.62±3.37)%,all P<0.05]was increased obviously,CD4~+/CD8~+ ratio in 30,60, 90 days[(1.703 ±0.201)%,(1.772±0.215)%,(0.991±0.124)%,P<0.05 or<0.01]also was increased obviously. The apoptosis ratio of spleen cells in fluorine group in 30,60,90 days[(2.31±0.36)%,(2.76±0.22)%,(3.04± 0.29)%]was higher than that in control group[(1.14±0.21)%,(1.23±0.23)%,(1.29±0.20)%,P<0.01].The apoptosis ratio of spleen cells in selenium antagonism group in 60,90 days[(2.42 ±0.32)%,(2.73±0.39)%]was lower than that in fluorine group(P<0.05 or<0.01).Conclusion A certain concentration of selenium can antagonize the immunity inhibition of fluorine by decreasing apoptosis and improving the unbalance of T-cell subset.
