Objective:To analyze the feature of anaphylactic shock induced by alprostadil injection. Methods: Totally 1624 pa-tients treated with alprostadil injection in our hospital from January to March 2014 were undergone adverse drug reaction monitoring. Six cases of anaphylactic shock induced by alprostadil injection were statistically analyzed. Results:6 cases of anaphylactic shock induced by alprostadil injection occurred in the department of intervention and most of thd reaction happened in arterial injection. Two lot num-ber of drugs were in high frequency. Patients showed a sharp fall in blood pressure, chest discomfor, palpitation, shortness of breath, paleness, sweating and other symptoms. After anti allergy, blood pressure, oxygen the rapy and other treatment measures vital signs gradully stabilized. Conclusion:Anaphylactic shock induced by alprostadil injection is in correlation with the administration mode of artery injection. The change of the patient' s condition and vital signs should be closely observed when we inject the patient with alpros-tadil injection. We must prevent the occurrence of serious adverse reactions.

Objective To investigate the diagnostic significance of endoscopic findings in Henoch-Schonlein purpura(HSP),especially when abdominal pain preceded the cutaneous lesions.Methods The clinical data and gastroscopic findings in 37 cases of children with HSP were studied and analysed retrospectively in order to detect the pathological changes in the stomach and duodenum mucosa.The biopsy was taken in the pathological changeing place,and the relationship between clinical and endoscopic findings was analyzed.Results Detection rate of the pathological changes in the stomach and duodenum mucosa was 62.2%,31.3% of which experienced only cutaneous lesions,100% of which presented the acute abdominal pain.Three patients were not checked up the pathological changes.Of them,1 had arthritis,2 had Henoch-Schonlein nephritis.Characteristically endoscopic findings in the stomach and duodenum mucosa were found.The endoscopic findings included anabrosis,hyperemia,edema and hemorrhage.Conclusions Detection rate of the pathological changes in the stomach and duodenum mucosa is higher.Endoscopy is very helpful to the early diagnosis of HSP in children,especially abdominal pain presented firstly.

AIM To observe the endometrium receptivity of polycystic ovary syndrome patients and research advance of expression of HOXA10 in endometrium.METHODS Eighty PCOS patients were divided into treatment group and control group,40 persons in each group randomly.The control group was treated with clomiphene (CC) + human menopausal gonadotropin (HMG) + human chorionic gonadotropin (HCG),and the treatment group was treated with CC + HMG + HCG + Yin-Nourishing Yang-Supplementing.After 3 periods,take a record for below:endometrial thickness (Em) in the middle,advanced stage and mid-secretory phase of hyperplasia endometrii,the levels of spiral artery PI/RI in midluteum endometrium,the levels in serum of E2 and P in midluteum endometrium,the expression of HOXA10 mRNA from both groups,clinical pregnancy rate and abortion rate for each group.RESULTS Compared with the control group,endometrial thickness in the treatment group was increased and there is statistical difference in the middle and late follicle phases (P ＜ 0.05),but there was no statistical difference in midluteum endometrium (P ＞ 0.05);the level of E2 and P in the treatment group were raised (P ＜0.05) with statistical significance;PI and RI were obviously contracted (P ＜ 0.01).Expression of HOXA10 mRNA was increased (P ＜ 0.01).Compared with the control group,the treatment group had a significant difference in pregnancy rate (P ＜ 0.05).The abortion rate was lower,but there was no statistical significance (P ＞ 0.05).CONCLUSION Yin-Nourishing Yang-Supplementing Treatment can obtain higher pregnancy rate and lower abortion rate of PCOS patients and the mechanism might be associated with raising the expression of HOXA10 mRNA and reducing spiral artery PI/RI,also improving the function of corpus luteum treatment,then to improve the receptivity of endometrium.Yin-Nourishing Yang-Supplementing Treatment is well worth popularizing in further clinical application.

Objective To study the gait of children with spastic cerebral palsy (SCP) using plantar pressure measurement (PPM).Methods Twenty SCP children and 84 healthy children were recruited,and PPM was used to compare their gait cycle time,cadence,and standardized gait cycle parameters.Results Compared with the control group,gait cycle times in the SCP group were obviously prolonged,and their cadence was significantly slower.The side support phase and swing time in the SCP group were shorter,while the double support phase was longer than that of children in the control group.Conclusion PPM can be used to assess the gait of SCP children efficiently.

Objective To investigate the influence of electrocardiogram(ECG)-controlled dose modulation on exposure dosage and image quality of cardiac CT imaging in a cardiac phantom with simulated fluctuant heart rate.Methods The basal heart rate of the cardiac pulsating phantom was set as 60 bpm.the experimental situations were divided as 6 groups according to different heart rates.The cardiac imaging was performed on the cardiac phantom when the ECG-controlled dose modulation was firstly turned off.The exposure dosage of each scan sequence was documented.The standard deviation of the CT values of the phantom was measured on the central slice after coronal reformation of the raw data.The quality of 2D and 3D images were scored.Thell cardiac imaging was performed when ECG modulation was on and set as four groups according to different modulation parameters.All the data were documented as before.The results from the five groups with and without ECG modulation current were analyzed bv F test and comparative rank sum test using the statistical software SPSS 10.0.Results Statistical analysis showed no significant difference(P＞0.05)between the SNR of images(SD value was 27.78 and 26.30)from the groups that full mA output at wide reconstruction phase(69%～99%)when the heart rate was fluctuant(≥7.5 bpm).There was also no significant difference(P＞0.05)between the quality of the 2D and 3D images.But there was a significant difference(P＜0.01)between the SNR of images(SD value was 26.78 and 29.90)that full mA was only used at 85%reconstruction phase when the heart rate Was fluctuant(≥7.5 bpm).The exposure dosage was remarkably reduced when the ECG modulated current was on than when it Was off under fluctuant heart rate.Furthermore.there were significant difierence(P＜0.01)among the difierent ECG modulated current parameter groups.The exposure dosage can be reduced by 44.7%under the situation that the heart rate was fluctuant.Whell the fluctuation of the heart rate was≤12.5 bpm,there wag no obvious relationship between the fluctuation of the heart rate and the exposure dosage (the variation was from 0.1 to 1.1 mSv),but if the heart rate fluctuation was＞12.5 bpm,the exposure dosage would increase obviously (from 0.6 to 1.7 mSv).Conclusion For cardiac imaging with 16-slice row CT,the application of ECG modulated current can effectively reduce the exposure dosage without compromising the image quality even if heart rate was fluctuant.

Objective To evaluate the effect of low-dose colonic CT scanning in image quality and lesion revealing with different noise idex.Methods Model group:in order to find the optimal scanning parameter range,small simulated polyps in pig colon was prepared and mA was modulated by regulating noise index.Images were reprocessed with CT colonography and Raysum reconstructions.Image quality and the lesion revealing situation were evaluated and scored based on both reconstructive and axial images.The study of patient group was prospective and continuous.All positive cases were comfirmed by biopsy or surgery pathology.Two groups of patients were enrolled.First group(39 cases from January 2007 to June 2007):patients were divided into three sub-groups randomly(15 cages with NI=10,13 cases with NI:13,11 cases with NI=16),while NI was not changed with position.Second group(32 cases from Jury 2007 to January 2008):patients were scanned and NI was changed with different position(NI=10,20).The average X-ray radiation values of two patient groups were compared with standard values.All data were processed with rank sum tesL Results First group:when NI=10,the average scores of axial and constructive images were 4.2 and 2.4 respectively,when NI=13,those were 3.2 and 2.5 respectively,When NI=16.those were 2.9 and 2.7 respectively.and the average CTDlw were 17.51,12.90 and 5.94 mGy respectively.When NI increased,the average scores of axial decreased(H=20.01,P＜0.01),the average scores of constructive images did not changed(H=0.81,P＞0.05).Second group:when NI=10,the average scores of axial and constructive images were respectively 3.6 and 2.3,when NI=20,those were 2.2 and 2.3 respectively,and the average CTDIw was 11.63 mGy.When NI increased from 10 to 20,the average scores of axial decreased(H=20.84,P＜0.01),the average scores of constructive images did not decreased(H=0.29,P＞0.05).In the first group,the average CTDIw wag reduced by 35.0%,52.1%and 77.9%respectively when NI was 10,13 and 16.In the second group,the average CTDIw Was reduced by 56.8%.Conclusions Auto-mA low-dose CT scanning could reduce X-ray radiation obviously,while not affecting image quality.
