Objective Under the requirements of dose distribution in target and normal tissue ,five radiotherapy fields are de‐voted to making Intensity‐modulated radiation therapy (IMRT) plan ,thus the IMRT radiotherapy of Nasopharyngeal Carcinoma (NPC) could be underway with the radiotherapy field as few as possible .Methods Through the comparison of the NPC patients′IMRT plans in our hospital ,the angle of fields have been make out with 0° ,75° ,125° ,225°and 285° .At the same time ,this field scheme is compared with projects of front five fields ,behind five fields and share five fields .The result was statistically analyzed . Results In these four field schemes ,the maximum and minimum dose in the target area showed no statistically difference (P>0 . 05) ,while in the average dose ,D95 and normal tissue dose have statistical difference (P<0 .05) .Conclusion Comprehensive com‐parison of the dose distribution in the target and normal tissue in these four field schemes showed that the field scheme with the an‐gles of 0° ,75° ,125° ,225°and 285°could obtain better results ,so this field scheme should be more suitable for local area NPC patient′s IM RT .

AIM: To study effects of hyperbaric oxygen (HBO) and cyclosporin A (CsA) on the contents of active oxygens and nitric oxide (NO) in spleens of skin transplanted mice. METHODS: The donor mice BALB/C and receptor mice Cs7BL/6 were tested for skin transplantation. The HBO group mice were,treated with 99.2 % oxygen under 0.25 MPa for 1.5 hours, while CsA group mice were treated with CsA 0.5 rmg· kg- t· d- 1 by abdomen injection. After 14 days, the spleen were extracted the contents of malondialdehyde (MDA) and NO and the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH - PX), catalase (CAT) and NO synthases (NOS) were determined. RESULTS: (1) Compared with the control group, the transplantation group, HBO group and CsA group have markedly increased the content of MDA and the activities of GSH - PX and CAT; Compared with the transplantation group, the CsA group have markedly increased activity of SOD and reduced activities of GSH - PX and CAT; the HBO group have markedly reduced the activity of GSH - PX and increased the activities of CAT and SOD (P < 0.01 ). (2) Compared with the control group, the transplantation group have markedly increased the content of NO and the activity of NOS; Compared with the transplantation group, the HBO group have markedly increased the activity of NOS and reduced the content of NO ( P < 0.01 ); The content of NO and the activity of NOS in CsA group was not changed significantly. CONCLUSION: In the lymphocytes of the transplantation group, the peroxidation is intensified, and the content of NO and the activity of NOS increased. HBO and CsA may activate the systems of oxidation/antioxidation and NO/NOS in spleen, which may be related to their mechanism of inhibition rejection.

Objective To explore the feature of electrical physiology and the key aspect of diagnosis in early stage of spinal muscular atrophy in infants.Method The back clinical data of the musle change of electrical physiology within 25 cases were analyzed.Results The children were ill in 1 year old,with the symptom that four limbs present symmetry and paralysing slowly,low limbs being more serious than upper limbs,the close and the distant of the four limbs.The levels of creatine kinase(CK) and lactate dehydrogenase(LDH) in serum were normal and the case unconcentrated was not seen rarely.The show of electromyogram(EMG) was that three limbs presenting wide-range losing nerve electric potential in peace state,when straingently the deadline was long and the motor unit potential(MUP) was high,when strain highly the eletric potential was decreased;the speed of nerve conduction was common.Muscle inspection was typical nervine myatrophy.Conclusion The clinical feature,the changes of muscle electrical physiology and the muscle inspection are valuable for diagnosis so as to afford reliable evidence for further gene diagnosis.J Appl Clin Pediatr,2006,21(3):167
