Objective To study the CT performances and literature review of myoepithelioma (ME)of the parotid gland,to improve the recognition and diagnostic accuracy of this disease.Methods The CT findings of 1 2 cases with ME of the parotid gland confirmed by surgery and pathology were analyzed retrospectively,the characteristics of the age of onset,gender,size,location,density,boundary and enhancement were analyzed.And then,the related literatures were reviewed.Results Among the 1 2 patients,5 were male and 7 were female,age ranged from 11 to 68 years old,with a median age of 45.2 years.2 patients had the symptom of tenderness and fever, and the other 10 patients were asymptomatic and painless preauricular mass,2 of which were gradually enlarged.All the tumors were single in this study,2 had visible capsule infiltration or unclear boundaries,and other 10 had intact or smooth edges.CT showed that the masses all located in the parotid gland(1 in the deep lobe and 11 in the superficial lobe).The diameter of the tumor was 10 mm to 50 mm,with an average of 29.1 mm.The density was uniform in 2 cases and irregular cystic degeneration and necrosis in the other 10 cases.Mild enhancement was found in the arteriovenous phase after enhanced scanning,in which 8 cases had marginal enhancement or nodular enhancement in the arterial phase,and gradual filling into the center in the venous phase.Conclusion The CT performances of ME of the parotid gland have define characteristics.The possibility of myoepithelioma of the parotid gland should be taken into account when it has continuous centripetal reinforcement after enhancement,combing with the single cystic solid mass with clear boundary in superficial lobe of the parotid gland.Malignant myoepithelioma (MM)should be considered when the tumor envelope is incomplete or the boundary with the surrounding structure is not clear.

OBJECTIVE：To provide reference for improving the pharmaceutical care in China. METHODs ：By comparing the development history ，training contents and status quo of the standardized training system of resident pharmacists in Beijing and clinical pharmacists in China ，combining with policy guidance of the current development trend of clinical pharmacy ，the regins were discussed to optimize the mode of standardization training for inpatient pharmacists in Beijing. RESULTS & CONCLUSIONS：Standardized training for resident pharmacists in Beijing was a compulsory post-graduate education for pharmacists in Beijing hospitals. Post training of clinical pharmacists mainly focused on post-graduate education ，and the main training content was the practical ability of pharmacists in clinical pharmacy ，could be divided to general clinical pharmacists and specialized clinical pharmacists. The standardized training for resident pharmacists in Beijing consisted of two stages ，the first stage was general skills training ，the second stage was specialized skills training. The training content and rotation department of clinical pharmacy in the first stage were similar to post training of general clinical pharmacists in China ，and the training assessment required was more workload for trainees ，but it was not the key point of completion assessment for standardized training of resident pharmacists. During 2015-2017，154 trainees completed the training in Beijing and participated in the second stage completion examination of the standardized training of the resident pharmacists. At the same time ，43 trainees（27.92％）participated in the training of clinical pharmacists. 228 trainees participated in the training of clinical pharmacists in Beijing during the same period ， and showed an increasing trend ；most of them had passed the Beijing standardized training for resident pharmacists. It is suggested that the standardized training of resident pharmacists in Beijing can absorb the advantages of post training of clinical pharmacists. In the first stage of training ，the post training of general clinical pharmacists should be carried out at the same time. The post training of specialized clinical pharmacists can be included in the two-stage training of inpatient pharmacists.

Objective: To study the relationship between STAT3 gene (rs2293152, rs957970) polymorphism and susceptibility to bronchial asthma in children, and to lay the foundation for search of the candidate pathogenic gene of asthma and early prevention of the disease. Methods: One hundred and thirty hospitalized asthmatic children or out-patients with asthma at Affiliated Hospital of Southwest Medical University from September 2013 to September 2017 were selected as asthmatic group, and at the same time 145 healthy children were selected from the Affiliated Hospital of Southwest Medical University as the healthy control group.Apply sequence specific primers-polymerase chain reaction (SSP-PCR) was applied to detect susceptibility single nucleotide polymorphism (SNP) of STAT3 gene (rs2293152, rs9579700). The statistical differences in distribution between genotype and allele were analyzed between the asthma group and the healthy control group. Results: The distribution frequency of CC genotype of rs2293152 in STAT3 gene was significantly higher in the asthmatic group (19.2%)than that in the healthy control group (9.0%) (χ²=6.065, P=0.014). C allele was significantly higher in asthmatic group (41.9% vs.33.8%) (χ²=3.861, P=0.049). There was no significant difference in the distribution of rs957970 in STAT3 gene between the asthma group and the healthy control group. Conclusions The SNP of rs2293152 in STAT3 gene is associated with susceptibility to asthma in children in South Sichuan.C allele may be the susceptible gene for childhood asthma, while the SNP of rs957970 in STAT3 gene has no significant correlation with childhood asthma in Southern Sichuan.
