AIM: To build an allergic rhinitis model to evaluate the effect of budesonide on the eosinophils and histamine in nasal mucosa in allergic rhinitis guinea pig.METHODS: 33 guinea pigs were randomly divided into three groups: natural controlled group,allergic rhinitis(AR) group and budesonide treatment group.Allergic rhinitis model in guinea pigs were built by using toluene-2,4-disocyanate(TDI) nasal immunization and challenge.The indexes of clinical symptoms,pathomorphological diagnosis and content of histamine in mucosa were used to evaluate the potency of budesonide when used to treat allergic rhinitis.RESULTS: The expression of eosinophils and the content of histamine in nasal mucosa in AR group both were significantly higher than that of in natural controlled group(respectively,P(0.05)).CONCLUSION: Budesonide could effectively reduce the expression of eosinophils and content of histamine in nasal mucosa,but it is invalid in releasing the symptoms of AR in guinea pig.The reason of this phenomenon may be concerned with the method of model building.

AIM: To evaluate the changes in central corneal thickness (CCF) caused by mydriasis with Mydrin-P.METHODS: A total of 106 eyes of 53 patients with refractive errors were studied. Each eye had instillation of Mydrin-P to obtain mydriasis. CCT was examined before and after mydriasis using ultrasonic pachymeter.RESULTS: CCT increased significantly after mydriasis with Mydrin-P.CONCLUSION: Mydrin-P can affect the measurement of CCT.

Objective To study the effect of early nutrition on the development of physique and small intestine inrats with intrauterine growth retardation (IUGR). Methods Eight normal pubs fed with normal protein diet (20 % )were used as normal controls. The IUGR pups were assigned into normal protein diet group (IC group), low-protein dietgroup (IL group) and high protein diet group (IH group). On the 1st, 21st and 28th day after birth respectively, theweight and length of small intestine (SI), the body weight and length, and the activities of disaccharidase weremeasured. Results The body weight and length, weight and length of SI in rats with IUGR at birth were allsignificantly lower than those in normal rats ( P ＜ 0.05). Body length, body weight, length and weight of SI in ILgroup were all lower than those in IC, IH and normal control groups in the first 4 weeks after birth. The physique andsmall intestine in IH group caught up growth quickly, the body weight in the 4th week reached the normal value. In thethird week, the lactase activity in IL and IH groups were higher than that in normal control group ( P ＜0.05). In the4th week, the sucrase activity in IL group was lower than that in normal control ( P ＜ 0.05). Conclusions Earlynutrition after birth has an important effect on the development of physique and SI in rats with IUGR.

Objective To report two cases of severe pulmonary complication after bortezomib treatment for multiple myeloma. Methods Two cases of severe pulmonary complication after bortezomib treatment patients with relapsed multiple myeloma wereas discussed with review of literature. Results Two relapsed MM patients were treated with bortezomib and thalidomide or dexametbasone. Cough, dyspnea, fever and hypoxia developed after completion of bortezomib. Chest X-ray revealed bilateral pulmonary infiltrates,but infection was not identified with sputum cultures, and broad-spectrum antibiotics were ineffective.Conclusion Severe pulmonary injury was rare complication in patients receiving treatment for multiple myeloma, however, it was a life-threatening disorder. Prophylaxis corticosteroids maybe effective. Although corticosteroids are effective, but the mechanism of lung injury associated with bortezomib is unclear, and further evaluation of this potential toxicity is appropriate.

Objective To investigate the clinical value of serum follicle stimulating hormone(FSH) and testicular volume in the etiology diagnosis of azoospermia.Methods The clinical data of 373 patients with azoospermia were analyzed retrospectively.The patients were divided into the group A,B and C according to their FSH detected level.The FSH level was normal in the group A,slightly increase in the group B and severe increase in the group C.The testicular volume and the spern retrieval success rate of each group were analyzed statistically.Results The testicular sperm retrieval success rates in the group A,B and C were 70.81％,22.22％ and 0 respectively;the average testicular volumes in the three groups were(11.39±5.06),(8.79±4.18),(6.96±4.12)mL respectively,the differences among the three groups were statistically significant(P＜0.05).Conclusion In the patients with azoospermia,the FSH level and testicular volume help to judge the testicular spermatogenic functional status and identify the type of azoospermia.

We reviewed the modern development of clinical application and experimental reseach on the prescription Biejiajian Wan (BJ), which are the basement that we will study its anti-renal fibrosis. At present, the prescription BJ is mainly applied to the treatment of chronic heptic desease. Its experimental reseach is mainly confined to the studing of anti-heptic fibrosi. Refering the scientific and technological result of anti-heptic fibrosis, we think the prescription BJ would have the effection of anti-renal fibrosis on the basis of theory of planning treatment according to diagnosis. But it has not been reported to the prescription BJ on the clinical and experimental reseach on anti-renal fibrosis. Therefore, it is very important to take on clinical reseach of the prescription BJ and discuss the effecting mechanism of anti-renal fibrosis from the level of integration, cell and molecule, which will help to enlarge the clinical application of the prescription Biejiajianwan and explained the essence of "persistent diseases injuring collateral branch of large channel" in traditional Chinese medicine.

OBJECTIVETo study the impact of different planning target volume (PTV) margin settings on surface and superficial dose distribution and explore the resolution of high superficial dose when the target area is close to the surface during head and neck intensity-modulated radiotherapy (IMRT).

METHODSA typical superficial target volume was designed in an circular neck phantom. Two experimental inverse IMRT plans were conducted with 8MV X ray, and in plan A, the superficial side of PTV margin ranged from 0 to 5 mm, while other side margins were 5 mm; in plan B, an suppositional machine dosimetry data for IMRT optimization was established in which the build-up dose was eliminated, and this machine data was used to optimize the inverse IMRT plan followed by recalculation of the planned dose distribution with the actual clinical machine dosimetry data. The variation of the surface and superficial dose resulting from set-up error and the dose distribution to CTV were compared. The adequate PTV margin was analyzed when the CTV approached the surface.

RESULTSIn plan A, the high dose greater than the prescribed dose was found in the surface and superficial region when the superficial sparing distance was between the surface and PTV d<3 mm, and the 3 mm set-up margin increased this superficial dose remarkably. Reducing the superficial side of PTV margin lowered the high superficial dose effectively and allowed maintenance of the prescribed dose to the CTV. To avoid reduction of the dose to the CTV to below 95% of the prescribed dose, the superficial side of PTV margin should be greater than 1 mm. Plan B effectively lowered the surface doses and maintained the prescribed dose to the CTV.

CONCLUSIONSWith appropriate techniques for optimizing inverse IMRT, more homogeneous superficial dose can be achieved.
