ABSTRACT
<b>Objective</b> To evaluate clinical efficacy of lung transplantation for lung chronic graft-versus-host disease (cGVHD) after hematopoietic stem cell transplantation (HSCT). <b>Methods</b> Clinical data of 12 patients undergoing lung transplantation for lung cGVHD were retrospectively analyzed. Preoperative clinical manifestations and involved organs of patients were analyzed. The lung function before and after lung transplantation was compared, and the survival of patients after lung transplantation was analyzed. <b>Results</b> Eleven patients underwent HSCT due to primary hematological malignancies, including 9 cases of leukemia, 1 case of myelodysplastic syndrome, 1 case of lymphoma. And 1 case underwent HSCT for systemic lupus erythematosus. Among 12 cGVHD patients, skin involvement was found in 8 cases, oral cavity involvement in 5 cases, gastrointestinal tract involvement in 4 cases and liver involvement in 3 cases. All 12 patients developed severe respiratory failure caused by cGVHD before lung transplantation, including 9 cases of typeⅡ respiratory failure and 3 cases of type Ⅰ respiratory failure. Two patients underwent right lung transplantation, 2 cases of left lung transplantation and 8 cases of bilateral lung transplantation. The interval from HSCT to lung transplantation was 75 (19-187) months. Upon the date of submission, postoperative follow-up time was 18 (7-74) months. Ten patients survived, 1 died from severe hepatitis at postoperative 22 months, and 1 died from gastrointestinal bleeding at postoperative 6 months. No recurrence of primary diseases was reported in surviving patients. <b>Conclusions</b> Lung transplantation is an efficacious treatment for lung cGVHD after HSCT, which may prolong the survival time and improve the quality of life of the recipients.
ABSTRACT
Objective To explore the role of a new apoptosis related gene TFAR 19 in the pathogenesis of systemic lupus erythematosus (SLE) and the relationship between TFAR 19 and SLE.Methods ELISA was used to test if there is relation between TFAR 19 and SLE.Results It was found that in active SLE patients there was higher titer of TFAR 19 antibody than that in stability patients and normal controls.No significant difference was seen between stability patients and normal controls.Conclusion It is first put forward that TFAR 19 may be related with SLE pathogenesis and disease activity.
ABSTRACT
The putative allergens,clinical manilestations and patch tests of traditional Chinese medicinal materials (CMM) which cause contact dermatitis (CD) are studied in this paper. 14 patients with CMM CD and 351 controls were patch tested with the standard series of allergen produced by the Beijing Medical University and the suspected drugs been tised. It was found that most CMM CD were caused by the CMM frequently used topically for "analgesic and antiphlogistic". All the patients patch tested with suspected drugs gave positive results. Some patients also reacted to fragrance mix, colophony, rubber mix and ammoniated mercury. The positive rates of fragrance mix and colophony in CMM CD patients were significantly higher than controls while rubber mix and ammoniated mercury were not. The results indicated that the topical analgesic and antiphlogistic CMM especially those containing fragrance may be liable to cause sensitization. CMM CD can be diagnosed by patch testing the putative drugs.
ABSTRACT
Objective To investigate the therapeutic effect of oral viaminate(a vitamine A acid derivative)on acne and its effect on the expression of androgen receptor.Methods Two hundred and eigh-teen patients with acne were allocated to treatment group and control group at random:treatment group was treated by oral viaminate;control group was treated by oral minocycline.The treatment lasted for four weeks.The effect of viaminate on the expression of androgen receptor was studied in COLO-16cells in vitro by using Northern blot or Western blot.Results The therapeutic effect of oral viaminate in treatment group was higher than that in control group(P
