Objective To discuss CT techniques and features of gastric antrum canser.Methods The findings of gastric antrum cancer were analysed in 38 cases with the review of literature.Results The CT findings of gastric antrum cancer were thickening of gastric wall,formation of soft tissue tumour,narrowing of gastric antrum lacuna and in combination with ulcer.The duodenum and around stomach could be invaded by tumor.Conclusion The full view of gastric antrum carcinoma and its relation with adjacent organs can be distinctively showed by CT.

Objective To study the clinical characteristics of Henoch-Sch(o)nlein purpura (HSP) in children.Methods We retrospectively analyzed the clinical data of 124 children with HSP.Results Among these 124 children,54.84% of the children presented upper respiratory tract infection before the onset of HSP.The purpura recurred in 30 of 47 children with Henoch-Sch(o)nlein purpura nephritis and in 22 of 77 children without Henoch-Schonlein purpura nephritis,respectively (P＜0.05).The incidence of Henoch-Sch(o)nlein purpura nephritis was significantly higher in children who had purpura,gastrointestinal symptoms,and joint symptoms simultaneously than in those only with purpura (P＜0.05).The elevated levels of IgA and C reactive protein were found in 67.35% and 39.39% of the children,respectively.Conclusion The most important predisposing factor of HSP is upper respiratory tract infection.The children with recurrence of purpura or those who have purpura,gastrointestinal symptoms,and joint symptoms simultaneously are more likely to present renal damage.

Objective To propose a method to calculate sample size for survival analysis in single-arm trials.Methods Through theoretical formula derivation,we provided sample size estimation method for survival analysis in single-arm trials.Monte-Carlo simulations using STATA software were conducted to obtain the empirical power,so as to verify the accuracy of the estimated sample size.Results Simulation results showed that,when α =0.025 and α =0.01,the power of the sample size calculated by the formula is in accordance with the predetermined power.Conclusions The formula of sample size estimation we proposed could achieve the predetermined power for survival analysis in single-arm trials.Findings of this study provide reliable basis for sample size estimation of early stage antineoplastic drug clinical studies.

Objective　To observe the influence of intravenous anesthesia with ketamine or propofol on intraocular pressure (IOP) in pediatric patients. Methods　27 pediatric patients, ASA grade Ⅰ～Ⅱ, were divided into ketamine and propofol groups. Basic anesthesia was conducted with ketamine 4～6 mg*kg-1 combined droperidol 0.04～0.1 mg*kg-1 intramuscularly. Anesthesia maintained with continous infusion of 0.04% ketamine or 0.04% propofol following intravenous bolus of ketamine 1 mg*kg-1 or propofol 1 mg*kg-1 in ketamine group and propofol group respectively. IOP, systemic blood pressure(SBP), diastolic blood pressure(DBP), heart rate(HR) and pulse oxygen saturation(SpO2) were measured at 10 minutes after basic anesthesia, 3 minutes after intravenous bolus of ketamine or propofol and end of surgery. Results　There were no differences in IOP between two groups after basic anesthesia. IOP increased or decreased significantly after intravenous bolus of ketamine or propofol respectively. IOP in ketamine group decreased near to the level in propofol group at end of surgery. There were no statistic differences in SBP, DBP and HR between two groups priopration. SpO2 did not change (but in one patient decreasing to below 95% ) and significantly decreased within 5 minutes of intravenous bolus of ketamine and propofol respectively. Conclusion　Ketamine increases IOP propofol decreases IOP. Ketamine combined propofol can keep from increase of IOP but strength respiration inhibition.

Objective To observe clinical effect of treating ophthalmoplegia with acupuncture combined with point injection. Methods 25 cases patients with ophthalmoplegia were randomly recurited into a control group and a treatment group. The control group was treated with western medicine and the treatment group was treated with acupuncture combined with point injection. The clinical effect of both groups was observed after treatment. Results The clinical effect in the treatment group was significantly higher than that of the control group (P<0.05) . Conclusion The treatment of ophthalmoplegia with acupuncture combined with point injection has a good effect.

0.05). After operation about 50% cases (11/22) improved the menstrual dysfunction, and most cases avoid doing operation again in short period. Conclusion While cases chosen properly and adequate operative preparation, it is feasible and valuable to carry out cesarean section and myomectomy at the same time.

Objective To observe the anti-aging effect of Yinao capsule. Methods The rat model of acute incomplete cerebral ischemia was established, and determined the content of superoxide dismutase (SOD), lipid peroxidation (LPO) and Evans blue in brain tissue, determined the serum SOD content of normal rats. Formed blood platelet thrombus by common carotid artery-external jugular vein blood flow bypass operation of rats, and weighed wet weight of thrombus. Results The Yinao capsule can increase SOD and Evans blue content of brain tissue from rat model of acute incomplete cerebral ischemia, at the same time, decrease the LPO content. It can enhance serum SOD content of normal rats, and inhibit the formation of experimental thrombus. Conclusion The Yinao capsule can prevent the occurrence of senile diseases, and defer organism aging.

OBJECTIVE To compare the air sterilization effect of in operating room used by different air sterilization methods.METHODS Four types sterilization methods were used to operating room air.Then sampling monitoring and evaluation were done.RESULTS The qualification rate of air sterilization were 79.17%,62.79%,79.63%,97.22% in peroxyacetic acid fumigating,simple ultraviolet radiation,peroxyacetic acid fumigating combined with simple ultraviolet radiation,ultraviolet light circulation wind air sterilization machine,respectively.The sterilization effect of ultraviolet light circulation wind was better than the others.CONCLUSIONS Ultraviolet light circulation wind air sterilization machine can be used to air sterilization in non-laminar air flow purify operating room.

OBJECTIVE To discuss the importance of communication in infection control.METHODS To eliminate the obstacles in infection control,we used different communication skills and manners to gain the aid from the leadership.RESULTS Both the leadership and everyone else in the hospital supported our work in infection prevention and control,for they had known the importance of infection control,especially in hospital.We communicated with them about the knowledge in this aspect in different means.CONCLUSIONS The professional technician should take different ways in communication to solve the problems in every department in the daily work,which can help us to achieve success in infection control.

Objective To observe clinical effect of treating blepharospasm with acupuncture. Methods 27 patients with blepharospasm were randomly recruited into a control group and a treatment group. The control group was treated with western medicine, and the treatment group was treated with acupuncture. The clinical effects of both groups were observed. Results Total effective rate in the treatment group and the control group was 85.7% and 69.2%, respectively. There was a significant dieffference between the two groups (P<0.05) . Conclusion The treatment of acupuncture on blepharospasm is better than western medicine.
