Objective To compared the decreasing characteristics of formaldehyde and benzene concentrations in indoor air after decoration. Methods The concentrations of formaldehyde and benzene in indoor air of hotels were determined within one week, one year and more than one year after decoration. Results The concentrations of benzene in indoor air reached the peak(mean: 0.534 mg/m 3) within one week after decoration, and then decreased gradually.The concentrations of formaldehyde were not high within one week after decoration,and then increased gradually, reached the peak (mean: 0.141 mg/m 3) within one year after decoration,then decreased gradually. Conclusion After decoration,the decreasing characteristics of the concentrations of formaldehyde and benzene showed a difference that the concentrations of benzene decreased faster than that of formaldehyde did.

Objective To investigate the epidemiologic features of infant rotavirus(RV) diarrhea in Guilin area .Methods The detection of group A rotavirus were performed on 1 300 patients from Guilin 181st hospital by using immune colloidal gold method , and the epidemiological analysis were done according to the detection results .Results In the 1 300 patients ,132 were found rotavir‐us positive ,the total positive rate was 10 .15% .The positive rate of >1-2 years old group was the highest(23 .08% ) ,compared with other age groups(P<0 .05) .In November ,December and January ,the positive rates were 24 .14% ,20 .00% ,23 .53% ,respec‐tively .Compared with the positive rate in other months ,there was statistically significant difference(P<0 .05) .Conclusion Infants of 6 months to less than 2 years old in Guilin have higher detection rate of RV infection ,and the infection peak appears in autumn and w inter .

Bosentan is a non-selective endothelin receptor antagonist,which plays an important role in the treatment of children with pulmonary arterial hypertension.Bosentan has shown to improve exercise capacity,hemodynamics and reduce pulmonary vascular resistance in pediatric patients.The main adverse effect is less severely comparing with the adult.The combination of bosentan with other drugs can improve the life quality furtherly.Further study of large-scale trials needs focus on the long-effects of bosentan,the ideal period of therapy and the effects of combination therapy in children.

Objective:To observe the correlation among cardiac function ,inflammation factor and plasma testoster‐one level in aged male patients with chronic heart failure (CHF) .Methods :A total of 91 male CHF inpatients were selected from our hospital ,including 31 cases with NYHA cardiac function class Ⅱ ,30 cases with class Ⅲ and 30 ca‐ses with class Ⅳ .Another 40 corresponding male patients without CHF were regarded as non‐CHF control group . Plasma levels of testosterone ,interleukin (IL)‐6 ,tumor necrosis factor (TNF)–α and brain natriuretic peptide (BNP) and cardiac function were compared between two groups .Results:Compared with non‐CHF control group , there were significant reductions in plasma testosterone level , P<0. 05 or 0. 01 ,and they more reduced along with NYHA cardiac function class rose in all CHF subgroups ,P<0.05 or <0.01 .Correlation analysis indicated that tes‐tosterone level was inversely correlated with IL‐6 and TNF‐α levels (r= -0.244 , -0.322 , P<0.05 both) ,and positively correlated with LVEF (r=0.322 ,P=0.01) .Conclusion:In patients with chronic heart failure ,the poo‐rer cardiac function is ,the lower plasma testosterone level is .Testosterone level measurement contributes to judging disease degree and prognosis of patients with chronic heart failure .

Objective To investigate the expression and significance of Smad4 in peripheral hepatocytes of lesions in mice with hepatic alveolar echinococcosis.Methods Eight mice in the test group were inoculated with alveolar echinococcosis and 8 mice in the control group were injected with normal saline.The expression of Smad4 protein in the hepatic tissue of the mice was detected by immunohistochemistry method,and the data were analyzed by chi-square test.The effect of alveolar echinocoeeosis on the expression of Smad4 protein was investigated.Results Smad4 was detected in cell nuclei and partly in the cytoplasm.Six months after the establishment of the mice model for alveolar echinococeosis,the expression of Smad4 in the hepatic tissue in the test group was significantly higher than in the control group(x2=19.869,P＜0.05).The number of Smad4 with positive expression in the hepatocytes in the test group was slightly higher than in the control group,and the expression intensity of Smad4 in the test group was greater than in the control group(x2=58.3 10,P＜0.05).Conclusions The increase of the expression of Smad4 protein in the periphery hepatocytes and tissues of hepatic alveolar echinococcosis lesions may play a role in hepatic cirrhosis and immune evasion.

Objective To investigate rheumatic disease manifestations in patients with myelodysplastic syndromes and explore possible causes.Methods Nine myelodysplastic syndromes(MDS)inpatients with rheumatic disease manifestations were reviewed retrospectively.Results Nine patients with the diagnosis of MDS had active rheumatic disease manifestations with various degree of hypergammaglobulinemia and positive autoantibodies.Two patients had rheumatoid arthritis(RA)and RA+anti-phospholipid syndrome(APS),four systemic lupus erythematosus(SLE)and SLE+polymyositis(PM),one patients had adult onset Still's disease, one with acute arthritis and cutaneous vassulitis,one had lupus-like manifestations including polyserositis,al- buminuria,hypocomplementemia and positive Commb's test.Conclusion The rheumatic disease manifesta- tions in patients with myelodysplastic syndromes are characterized by various active rheumatic disease manifes- tation.Immunological abnormalities and ineffective hematopoiesis are persistent.Immunologic abnormalities in MDS such as impaired function of T and B cells,hypergammaglobulinemia,positive autoantibodies,may be the causes of various rheumatic manifestations.We suggest that there is a significant association between myeludys- plastic syndrome and rheumatic diseases.
