OBJECTIVETo observe the therapeutic effect of Qingfei Huatan Quyu method (QHQ, a Chinese medicinal therapy for clearing Fei-heat and dissolving phlegm-stasis) combined with hormone-antibiotic therapy (HAT) on radiation pneumonia (RP).
METHODSEighty-one patients with RP were randomized into two groups, 41 patients in the control group and 40 in the treatment group were treated with HAT alone and HAT combined with QHQ respectively for 21 days. The severity of RP was evaluated before and after treatment according to the criteria of the radiation therapy oncology group. The effect on TCM symptoms and chest roentgenogram, as well as on plasma levels of interleukin-6 ( IL-6) and transform growth factor-beta (TGF-beta) were detected.
RESULTSAfter treatment, number of patients with RP graded as 0, 1, 2, 3, and 4 in the treatment group was 23, 10, 4, 2, and 1, respectively, while in the control group, 14, 9, 11, 4, and 3, respectively. The combined therapy showed effects in improving RP grading (P <0.01) and TCM syndromes were superior to those of HAT respectively (P < 0.05). Besides, levels of IL-6 and TGF-beta were lowered after treatment in the treatment group, showing a significant difference to those in the control group (P <0.05).
CONCLUSIONQHQ combined with HAT has a definite therapeutic effect on RP. It could efficiently decrease the plasma levels of IL-6 and TGF-beta in patients with RP.

Using matchmaker yeast two-hybrid system, it has been demonstrated that there exists an interaction between the cellular C terminal of alpha(1A)-adrenergic receptor (alpha(1A)-AR) and a segment of bone morphogenetic protein-1 (BMP-1). In the present study binding between the two proteins was further determined in human embryonic cell 293 (HEK293), a mammalian expression system. Mammalian expression vector PCP3HA was constructed by PCR and consisted of segments of BMP-1 cDNA, and vector PDT-alpha(1A) consisted of the full-length cDNA of human alpha(1A)-AR. They were transfected to HEK293 cells and examined by Western blot. alpha(1A)-AR and the segment of BMP-1 could be detected in the lysis of transfected cells. Then binding between alpha(1A)-AR and the segment of BMP-1 in HEK293 cell was determined by enzyme-linked immunosorbent assays (ELISA) and co-immunoprecipitation. In ELISA experiment, the ELISA microwell plate was first coated with anti-FLAG M2 antibody, which recognizes the FLAG-tagged alpha(1A)-AR, then the cell lysis, anti-HA rabbit polyclonal antibody and HRP conjugated anti-rabbit antibody were added in turn. The OD(490) values among the control group, PDT-alpha(1A) transfection group and PCP3HA transfection group, exhibited no significant difference (0.034+/-0.027, 0.042+/-0.019, 0.030+/-0.0096), but the OD(490) values of PDT-alpha(1A) and PCP3HA co-transfection group (0.57+/-0.12) were significantly higher than those of the other groups (P<0.001, respectively). In co-immunoprecipitation experiments, HEK293 cells expressing alpha(1A)-AR or/and segment of BMP-1 were lysed and incubated with anti-FLAG M2 antibody, then the immunoprecipitation pellet was immunoblotted with either the HRP conjugated anti-FLAG antibody or the anti-HA antibody, which recognizes the HA-tagged segment of BMP-1. Segment of BMP-1 was present in the pellet immunoprecipitation of PDT-alpha(1A) and PCP3HA co-transfected group. In conclusion, the results indicate that alpha(1A)-AR and the segment of BMP-1 are present in the same complex in HEK293 cells.

Variant pulmonary vein anatomy (PVA) has been reported to influence the recurrence of atrial fibrillation (AF) after radiofrequency ablation.However,the effects of PVA on AF in patients undergoing cryoballoon ablation (CBA) remain unknown.The present study aimed to examine the impact of PVA on the long-term outcome of CBA for AF.A total of 78 patients (mean age 60.7±10.9 years,64.1% males) with symptomatic and drug-refractory paroxysmal AF were enrolled in the study.Left atrium (LA) and PVA acquired at computed tomography angiography (CTA) were reconstructed with CARTO(R) 3 SYSTEM.Patients were routinely evaluated by 24-hour Holter monitoring following CBA.Cox regression was used to detect the predictors of AF recurrence after CBA.The results showed abnormal PVA in 30 patients (38.5%) and 18 patients (23.1%) had left common PV (LCPV).Electrical pulmonary vein isolation was achieved in all patients.After a mean follow-up of 689.5±103.8 days,it was found that patients with abnormal PVA had similar AF recurrence rate to those with normal PVA (26.7% vs.25.0%,P=0.54),and there was no significant difference in AF recurrence rate between LCPV patients and non-LCPV patients (33.7% vs.23.3%,P=0.29).Cox regression analysis showed that AF duration (72.9±9.0 vs.42.3±43.2 months,HR 1.001;95%CI 1.003-1.014;P<0.001) and cryo-applications of right-side PVs (3.0±1.6 vs.4.7±1.7,HR 0.661;95% CI 0.473-0.925;P=0.016) were independent predictors of freedom from AF,but PVA was not identified as a predictor of long-term success.In conclusion,the variant PVA cannot significantly influence the long-term outcome of AF patients undergoing CBA;longer AF duration and less cryo-applications of right-side PVs are associated with higher AF recurrent rate.

OBJECTIVETo investigate the biological behavior including survival and proliferation of CD34 + CD38--Lin--cells when they are cultured at single cell level.
METHODSPurified umbilical cord blood CD34 + CD38--Lin--cells were separated at single cell level in 96-well plates using flow cytometry for four groups: control group (CD34 + CD38--Lin--cell plus stem cell medium) , Shh group (CD34 + CD38--Lin--cell plus stem cell medium and Shh), BMP-4 group (CD34 + CD38--Lin--cell plus stem cell medium and BMP-4), Jagged-1 group (CD34 + CD38--Lin--cell plus stem cell medium and Jagged-1). Methylcellulose medium was used in the colony-forming experiment which was also in four groups as previously. The number of cells and colony-forming units in each well for the four groups was evaluated at different time points (day 1, 3, 7) with fluorescence microscopy counting method.
RESULTSDivision of single cell was observed to be amplified in all of these groups from day 3. And meanwhile, after 1-week culture, the survival rates for the treated groups were all higher than the control group (Jagged-1 group > BMP-4 group > Shh group > control), while the cell number in each well was also highest in the Jagged-1 group (Jagged-1 group > BMP-4 group > control). The number of wells with a cell number of zero was significantly fewer in all treated groups (especially the Jagged-1 group) than in the control group; meanwhile, the number of wells with a cell number higher than 17 was evidently higher in all the treated groups (especially the BMP-4 group) more than controls. Colony-forming units for erythroid (BFU-E), granulocyte (CFU-G), macrophage (CFU-M), and granulocyte macrophage (CFU-GM) were observed for all of these experimental groups, and there was no significant difference between the four experimental groups.
CONCLUSIONSCD34 + CD38 - Lin - cell can achieve the survival, self-renewal and proliferation when cultured at single cell level, and the adding of Shh, BMP-4, and Jagged-1 can enhance such capabilities. However, CD34 + CD38 - Lin - cell can only maintain cell totipotency in its niche.

OBJECTIVESTo explore the clinical characteristics of cardiac syncope (CS) in children, and understand their significance in predicting the cardiac syncope.
METHODSTwenty-three patients were referred to our department for evaluation of syncope. The diagnosis of the above cases was cardiac syncope. Each patient was interviewed using a standard questionnaire. The clinical histories and standard baseline electrocardiogram were analyzed to identify the variables contributing to the diagnosis of CS in children.
RESULTSA cardiac cause was identified in 23 syncopal patients presenting to the Department of Pediatrics, Peking University First Hospital: sick sinus syndrome in 7, congenital long QT syndrome in 4, third degree atrioventricular block in 2, supraventricular tachycardia in 2, ventricular tachycardia in 1, atrial fibrillation in 1, pacemaker dysfunction in 1, idiopathic pulmonary hypertension in 3, hypertrophic cardiomyopathy in 1, and dilated cardiomyopathy in 1. The average age of CS patients was 9 years. In totally 23 patients, exertion related syncope spells were found in 14 cases (60.9%), syncope spells at various position 7/23 (30.4%), absence of prodromes in 12/23 (52.2%), syncope spells with incontinence in 4/23 (17.4%), history of heart disease in 4/23 (17.4%). Abnormal standard baseline electrocardiogram was found in 21 cases (91.7%).
CONCLUSIONSThe children with cardiac syncope have overt clinical features, especially abnormal findings in electrocardiogram and exertion related syncope spells are the most common clinical features.
