Objective To investigate the changes of serum trace elements and nutritional proteins in children with acute lymphoblastic leukemia and acute myeloid leukemia at the stage of remission.Methods Erythrocyte count,hemoglobin,serum levels of total protein,albumin,iron,ferritin,transferrin,lactate dehydrogenase,ceruloplasmin,cuprum,zinc and their ratio were measured in 43 patients with acute lymphoblastic leukemia,19patients with acute myeloid leukemia at stages of remission(remission groups),and 30 healthy controls(control group)enrolled from Shanghai Children's Medical Center using atomic absorption spectrometry,nophelometry assay,dry chemical method,and chemiluminescence method.The differences of these indicators between remission groups and control group were analyzed.Results Serum levels of total protein(P=0.454),iron(P=0.769),transferrin(P=0.903),and zinc(P=0.343)were not significantly different between the remission groups and the control group.Serum levels of ferritin(P=0.000),lactate dehydrogenase(P=0.000),ceruloplasmin(P=0.000),cuprum(P=0.002),and Cu/Zn ratio(P=0.003)in the remission groups were significantly higher than those in control group.On the contrary,erythrocyte count(P=0.000),hemoglobin(P=0.000)and albumin(P=0.046)were significantly lowerin remission groups than those of control group.Serum levels of all detected indicators were not significantly different between the acute lymphoblastic leukemia remission group and acute myeloid leukemia remission group(P>0.05)except for lactate dehydrogenase(P=0.025).Conclusion At the remission stage of acute lymphoblastic leukemia and acute myeloid leukemia,serum levels of some trace elements and nutritional proteins gradually returned to normal,and the original balance is established again.

Objective　To study the indication, contraindication and short-term clinical effects of stereotactic radiotherapy (X-knife) in lung cancer. Methods　A total of 56 cases (Treatment group) of lung cancer were treated with X-knife composing of the modern 3-D treatment planning system and the stereotactic body frame, and SL-75 accelerator. And another 53 cases only treated with routine external radiation served as the control. In treatment group, 42 cases received 50 Gy radiation, at 2 Gy per day, 5 d per week in the upper mediastinum, hilus of lung, below the primary focus first and then underwent X-knife for the primary focuses, and other 14 recurrent and metastatic cases received irradiation of 8-12 Gy per day, 5 d by X-knife alone. Results　The actually reexamination rate for 1, 3, 6, and 12 months after X-knife treatment in 78 focuses from 56 cases was 79.5% (62/78), 89.8% (70/78), 87.2% (68/78) and 78.2% (61/78) respectively. The focuses reappeared in 3 months after the treatment and the growth rates of focus in 3, 6, and 12 month after the treatment were 2.6% (2/78), 5.1% and 9% (7/78) respectively. There were 2 focuses received a second treatment with X-knife because no change after the first one. Both the 1-and 2-year survival rates of 36 cases of the primary lung cancer in the treatment group were higher than that of control group (89.1%, 53.9% and 77.4%, 39.6%). Conclusion　The stereotactic radiotherapy is of applicable and prospective in the treatment of lung cancer. The indications include: ①As a boost dose in case when primary focus is less than 5 cm after the first external radiotherapy may reduce the exposure of lung tissue to x-ray and the occurrence of radiation pneumonia; ②Treatment for the recurrence after radiotherapy and operation; ③Radical treatment for the metastatic focus less than 5 cm. Attention must be paid to when multiple treatment is carried on the volume of the focus, the Karnofsky scores and the general condition when stereotactic radiotherapy combined with X-knife for lung cancer.

Objective Queuing theory is the mathematical study of how waiting lines or queues are formed and dissipated o -ver time, which aims to work out the optimal design and optimal control of queuing systems based on the research of probability and regularity of various queuing systems .The aim of paper was to find out the maximum acceptable waiting time for outpatients in stomatol -ogy department and explore the rational allocation of dentists based on queuing theory model . Methods Questionnaires , worktime measurement and queuing theory model were applied to calculate indicators of queuing system in outpatient services of Stomatology De -partment , getting the maximum waiting time accpetable for patients and the reasonable number of dentists . Results The maximum acceptable waiting time for outpatients was 34.02 ±7.07 minutes, and it was reasonable to allocate 25 doctors in the morning and 16 doctors in the afternoon . Conclusion Applying queuing theory helps to optimize dentist number in outpatient services of Stomatology Department and provide scientific reference to improve medical efficiency .

Objective To explore the clinical characteristics,relationship between treatment and prognosis of sarcoidosis and relationship of relapse to prednisone.Methods The clinical data of 165 patients with sarcoidosis were collected.The clinical characteristics,treatment process and prognosis,relationship of relapse with prednisone maintenance dose and course of treatment were retrospective analyzed.Results Among them,the most common involved systems were lung and lymph nodes.The involvement rates of lung,extra-thorax lymph nodes,cutaneous,ocular,salivary glands,liver & spleen,kidney and nervous system was 87.3％,51.5％,6.7％,6.1％,6.1％,4.2％,1.2％ and 1.2％ respectively.Unilateral tonsil,breast,ovary and bone involvement was seen in only 1 patient respectively with an involvement rate of 0.6％.A retrospective analysis was made for 114 cases with complete follow-up data.The mean follow-up period was (11.7 ± 5.7) (5-32) years.And 46 cases had no symptom on routine medical examinations.The most common consulted departments were respiratory,dermatological and general surgery departments.Among 74 patients on prednisone,48 patients (64.9％) were cured while 13 patients (17.6％) relapsed.Whereas in the observation group,25/38 patients (65.8％) remitted spontaneously and only 1 patient (2.6％) had recurrence.Relapse occurred more often in prednisone therapy group than in observation group (P ＜ 0.05).Longer prednisone 10-15 mg daily maintenance and a longer total course of treatment were associated with fewer recurrence(P ＜ 0.05).Conclusions The clinical manifestations of sarcoidosis vary and many patients have a self-limiting course.The most common involved systems are lung and lymph nodes.Stage Ⅰ / Ⅱ disease should be observed before prednisone therapy.Prednisone 10-15 mg daily for at least 6 months and a total course of treatment over 18 months may prevent relapse.
