Objective To investigate the change of lung function in children with atypical asthma and different lung function index to evaluate the difference of bronchial dilation test positive rate.Methods Seventy-one cases of atypical asthma children routine monitoring lung function,underwent bronchial dilation test,the airway index changes were observed.Results Seventy-one cases of atypical asthma children with big airways function index of forced expiratory volume in first second FEV1,percentage of FEV1 to forced vital capacity (FVC) were basic normal,and the reaction of small airways function index of forced expiratory flow at 25％ of FVC,forced expiratory flow at 50％ of FVC,forced expiratory flow at 75％ of FVC,forced expiratory flow at 25％-75％ of FVC were decreased in different degrees,and mainly for medium and severe damage.FEV1 as evaluation index,the positive rate of bronchial dilation test diastolic was 47.9％ (34/71),and forced expiratory flow rate at 25％-75％ in FVC as evaluation index,the positive rate of bronchial dilation test was 69.0％ (49/71),there was significant difference (x2 =8.086,P =0.004).Conclusions Lung function changes in atypical asthma children are mainly on small airways,and mainly for medium and severe damage,the bronchial dilation test positive rate in such children using the evaluation,forced expiratory flow rate at 25％-75％ in FVC can assist FEV1,decrease the rate of misdiagnosis and missed diagnosis.

Objective To investigate clinical and imaging features of malignant transformation in monostotic fibrous dysplasia (FD).Methods Radiography (n=12),computed tomography (CT)(n=7)and magnetic resonance imaging (MRI)(n=5)data of 12 monostotic FD cases proved by surgery and pathology were retrospectively reviewed.Results Among 12 cases,6 cases underwent surgery.Their images showed osteolytic lesions in the operative area with direct signs of aggressiveness (poorly defined margin,cor-tical destruction and soft tissue mass).For the 6 cases without surgery,radiography and CT showed poorly margin,osteolytic le-sions within or near the area of ground-glass opacity.MRI showed lesions with heterogeneous signal intensity and pronounced con-trast-enhancement.Histopathologically,9 cases were osteosarcomas,2 cases were fibrosarcomas,and 1 case was malignant fibrous histiocytoma (MFH).Conclusion The imaging information of malignant transformation of FD can provide evidence of possible ma-lignancy.

The action of BTHP on a-adrenoceptor was studied in anococcy-geus muscles, vas deferens and cell membrane of cerebral cortex of rats and aortic strips, saphenous vein of rabbit. BTHP produced parallel shifts to the right of dose-response curves for phenylephrine in rat anococcygeus muscle and rabbit aortic strips without change in the maximal responses. Their pA2 values were 5.8 and 5.86 respectively. BTHP was also a competitive antagonist for presynaptic and postsynaptic ?2-adrenoceptors on prostatic portion of rat vas deferens( pA2 against clonidine=5.2 ) and on rabbit saphenous vein ( pA2 against B-HT920=5.3 ) . BTHP decreased in dose-dependent manner 〔8H〕 prazosin and 〔3H〕 clonidine specific binding to ?1- and ?2- adrenoceptors on cell membrane of cerebral cortex in rats with IC50 of4 and 9.5 ?mol/L and with Ki ( apparent dissociation constant ) of 3.5 and 8.1?mol/L respectively, suggeating that BTHP has affinity for both ?1 and ?2- adrenoceptors of rat cerebrance.

Objective To investigate the image characteristics and clinical application of 18F-FDG PET/CT in autoimmune pancreatitis (ALP).Methods The PET/CT images from six male patients (age ranging from 51 to 78(average 69) years) with AIP from 2005 to 2012 were studied retrospectively.Of the six patients,two had follow-up PET/CT images after steroid therapy.The morphologic abnormality was visually analyzed and SUV was calculated.Scores were obtained according to the SUV of pancreas compared with that of the liver (3 =SUV higher than liver,2=SUV similar to liver,1 =SUV lower than liver).The difference between the regular and delayed SUV was compared by paired t test using SPSS 17.0.Results All of the 6 patients showed diffuse FDG uptake in the entire pancreas with SUVmax of 3.2-6.0(5.2± 1.1).Five patients had score 3 and one had score 2.Five patients had delayed scan,of which 4 had increased uptake (SUVmax5.3-7.2),but the SUVmax was not significantly different compared to that before delay scan (4.8-6.0,t =-2.424,P＞0.05).Five patients showed extrapancreatic uptake,especially in the salivary glands.After the steroid therapy,the enlarged pancreas reduced and the intense uptake of the pancreas disappeared.The extrapancreatic uptake showed coinstantaneous remission.Conclusions Increasing FDG uptake at entire pancreas was observed in patients with AIP.18F-FDG PET/CT may be useful for detecting AIP and the associated extrapancreatic uptake,and monitoring the change after therapy,yet it needs further evaluation.

Objective To evaluate the clinical efficacy and safety of traditional Chinese medicine on internal and external treatment of acne.Methods 128 patients in Dermatology Department of Xiyuan Hospital CACMS from May 2012 to March 2013 were collected and randomly divided into Chinese medicine group and western medicine group.The patients of Chinese medicine group were divided into invasion of the Lung by Wind-Heat syndrome and damp-heat oflmg and stomach syndrome,respectively taking acne liquid 1 or 2 orally and using the herb mask once a week.The western medicine group took Roxithromycin Capsules orally and smeared 0.3％ Viaminate and Vitamin E Cream.The treatment period lasted for 6 weeks,and collected the photograph of the target lesion before and after research every 2 week and evaluated the efficacy.Result The total efficacy rate were 90.77％ (59/65) and 74.60％ (47/63) for Chinese medicine group and western medicine group respectively,with significant difference between them(x2=11.83,P＜0.05).The efficacy rates were 87.50％ and 93.94％ for invasion of the Lung by Wind-Heat syndrome and damp-heat of lung and stomach syndrome respectively,with no significant difference between them(x2=0.416,P＞0.05).The TCM symptom scores after treatment [Chinese medicine group (4.36 ± 2.45),western medicine group (8.62± 2.49)] had significant difference in two groups respectively compared with before treatment[Chinese medicine group(15.33±6.08),western medicine group(14.34±5.29),P＜0.05].The difference of TCM symptom scores after treatment between the two groups also had a significant difference (P＜0.05).The TCM symptom scores after treatment of invasion of the Lung by Wind-Heat syndrome group and damp-heat of lung and stomach syndrome group were (4.50±3.01) and (4.24±1.83),which had a significant difference compared with before treatment respectively[(15.37±7.03)and(15.29±5.13),P＜0.05].Conclusion The TCM internal and external treatment on acne could reduce the number of lesions and improve TCM symptom scores.The effect of treating invasion of the Lung by Wind-Heat syndrome and damp-heat of lung and stomach syndrome with TCM was almost equal.

Interleukin-22 (IL-22) is a member of the IL-10 family, which exhibits a similar structure and immune function with IL-10. IL-22 is mainly secreted by Th22, Th1, and Th17 cells, innate lymphoid cells (ILCs), and γδT and NKT cells. IL-22 is mainly in-volved in autoimmune diseases, malignant tumors, and infective diseases. As such, studies have focused on the function of IL-22 cyto-kine in the pathogenesis of various malignant tumors. Studies revealing the expression and pathogenesis of IL-22 in malignant tumors possibly provide a new method to treat and prevent malignant tumors. In our study, the discovery, structural characteristics, and func-tions of IL-22 in malignant tumors are reviewed.

Objective To evaluate the effect of hypothermia on somatosensory evoked potentials (SSEPs). Methods Thirteen ASA Ⅱ or Ⅲ patients aged 23-51 yr weighing 45-82 kg scheduled for cardiac surgery were enrolled in this study. Bilateral median nerve SSEPs (N9, N13, N20) were recorded after induction.The MAP, peak latency and amplitude of N9, N13 and N20 were recorded when the target temperature (36, 35,34, 33 ℃ ) was reached during the cooling and rewarming periods. The neurological dysfunction was recorded after operation. Results The peak latency was prolonged and MAP was decreased with the decrease in the body temperature during the cooling period, the peak latency was shortened with the increase in the body temperature during the rewarming period ( P ＜ 0.05), but no significant change in the amplitudes was found ( P ＞ 0.05). The regression equation of the interaction between the peak latency and body temperature was YN9= -0.558X + 28.994(r=-0.673), YN13 =-1.121X+53.242 (r= -0.702) , YN20 = -1.458X+72.036(r= -0.702) during the cooling period (P ＜ 0.05), and YN9 = - 0.505X + 27.313 ( r = - 0.634), YN13 = - 0.905X + 46.249(r= -0.619), YN20 = - 1.142X + 61.668 (r= -0.600) during the rewarming period (P ＜0.05). No neurological dysfunction was found in all the patients. Conclusion Hypothermia can prolong the peak latency of SSEP and does not alter the SSEP amplitude.

Experiment Ⅰ. Twenty-eight rats were randomly assigned into Near-Infrared Information Radiation (NIIR) group and control group. Two weeks later each rat was innoculated intraperitoneally with Salmonella typhosa H antigen (HAg) and cyclophosphamide (CY). Peripheral lymphocyte counts in the NIIR group were significantly higher than those in the control group on the fifth day after administration of CY. Experiment Ⅱ, Fifty-four rats were randomly divided into NIIR group given CY and H Ag intraperitoneally, CY and H Ag group and H Ag group for treatment. By the end of the fourth week, the survival rate and serum IgG level in the NIIR group were significantly higher than those in the CY and HAg group. By the end of 2nd week, the titer of the anti-H antibody of the HAg group and NIIR group was significantly higher than that of the CY and HAg group. Experiment Ⅲ. Thirty rats were randomly allocated to NIIR group and control group. Spleen cells were taken and cultured with Con A for 24h to induce IL-2 and the activity of IL-2 in the NIIR group was significantly higher than that in the control group. The NK activity in NIIR group was higher but not significant and ADCC in the NIIR group was significantly higher than that in the control group. The results suggest that NIIR is capable of enhancing immunoreaction in immunosuppressive bodies by promoting the function recovery of T helper cells, therefore NIIR is effective to regulate the immunological function on chronic active hepatitis.
