Aim] To summarize and introduce the clinical experience of Chang Qing in the treatment of refractory asthma. [Method] To analyze the clinical experience and academic views of Chang Qing in the treatment of refractory asthma from the perspective of etiology and pathogenesis; and to discuss his basic prescription compatibility and flexible drug-applying characteristics. [Result] According to Chang Qing's clinical experience, while addressing the symptoms, treating the root is badly needed. He insists that in the period of acute exacerbation the adjustment of traditional Chinese medicine dosage should be used to rapidly bring the asthma under control until the symptoms disappear or obviously ease, then nourishing spleen and kidney to reduce the relapse of asthma. [Conclusion] In the aspect of treating the refractory asthma, Chang Qing has got rich clinical experience and effective. methods to relieve the asthma,his clinical dialectic thinking and the originality of prescription are greatly worth learning.

Objective To observe the effect of relative humidity on indoor concentrations of formaldehyde and ammonia. Methods 12 currently decorated rooms were randomly divided into 3 groups, 4 rooms involved in each, in which the average relative humidity of rooms were 55%,65% and 75% respectively. The concentrations of formaldehyde, ammonia were monitored every two days for 9 consecutive days according to GB/T18204.26 -2000 and GB/T18204.25-2000. Results The concentrations of formaldehyde and ammonia decreased gradually with the prolongation of the experimental period. The concentrations of formaldehyde in the rooms of 55%,65% and 75% relative humidity groups decreased significantly after the 5th, 3rd, 3rd day of the experiment compared with those in the same group at the 1st day of the experiment respectively(P

With the rapid development of intensity modulated radiation therapy (IMRT) technique,the accuracy of radiotherapy has improved,while the pretreatment dose verification has become more complex.Although the experimental measurements,a widely used way to perform dose verification,is accurate and effective,its time-consuming and labor-intensive is still a challenge for physicist.The independent dose verification method such as the depth dose-off axis ratios (OAR) empirical model,Clarkson integral model,convolution model and Monte Carlo model,could partially solve these problems effectively when the accuracy is ensured within a certain range.This approach could save physicists' time to conduct dose recalculation and plan check,and has become the hotspot in the world.This paper,therefore,mainly introduces the correction-based and the model-based independent dose verification methods,and briefly discusses the development of dose verification for IMRT plans.

Objective To investigate the changes and relationships between the serum endogenously produced interleukin-10(IL-10),nitric oxide synthase(NOS) and inducible nitric oxide synthase(iNOS) in acute myocardial ischemia and reperfusion.Methods Forty-two rats were randomly divided into two groups: myocardial ischemia and reperfusion group(the control group) and methylprednisolone treatment group.The rats in the control group and methylprednisolone treatment group received intravenous injection of placebo and methylprednisolone before ischemia respectively.The plasma IL-10,NOS and iNOS were detected at 0.5 h after ischaemia and 0.5h,2 h after reperfusion,respectively.Result The plasma IL-10,NOS and iNOS gradually increased at 0.5 h after ischaemia and 0.5h,2 h after reperfusion in the two groups.The levels of plasma IL-10 were significantly higher in the methylprednisolone treatment group in different time points than those in the control(all P

Objective To study the value of transthoracic echocardiography (TTE) in interventional treatment of congenital heart diseases. Methods TTE was used to identify patients with atrial septal defect (ASD, n=26), ventricular septal defect (VSD, n=23) or ductus arteriosus (PDA, n=16). They received interventional treatment with domestic made nitinol occluder. The TTE was then used to monitor the entire process of the surgery and to assess the effect of the surgery. Results The treatment with indigenous nitinol occluder failed in five patients, including two with ASD, two with VSD, and one with PDA. The other sixty-one patients were freated successfully with the occluder. Once the procedure was completed, those patients were found to have neither abnormal valvular regurgination as shown by TTE, nor any shunt flow around the occluder as shown by both TTE and angiocardiography. One month later, TTE demonstrated that the position of all the occluclers remained stable, and no residual leakage or shunt was detected by TTE in all of the sixty-one patients, and the same results were obtained after three months. However, two days after the surgery, ECG showed that three of the patients with VSD suffered from different degrees of atrioventricular block on the second postoperative day, but they eventually recovered after treatment. The successful rate of the procedure was 93.8% (61/65). Conclusions Transthoracic echocardiography may play an important role at three stages (pre-, during- and after), i.e. to select the most suitable patients before the procedure, accurately identify the location, and release of the occluder at the end of the operation; and finally, it serves as a promising method to evaluate the treatment result in patients during their follow-up period.
