Objective To analyze the differences of ADC values in breasts of women of different ages and different menstrual phases, so as to direct the choice of the examination time of MR DWI. MethodsThe breasts of 65 healthy volunteers were scanned with the routine MRI plain scan and DWI in the menstrual, proliferative and secretary phases. DWI was conducted with single shot echo planar imaging technique and b value were 0, 1000 s/mm2. The women were divided into three groups: Group 1(aged 20 to 29 years, 21 cases), Group 2 (aged 30 to 39, 21cases), and Group 3 (aged 40 to 49, 23 cases). The ADC values of all 130 breasts at nipple level in the different phases were measured. The ADC values in the three age groups and in the different menstrual phases were compared using ANOVA. Results The mean ADC values of Group 1 were (2.14±0.14) ×10-3, (2.03±0.18) ×10-3and (2.10±0.19)×10-3mm2/s for left breast, and (2.08±0.17) ×10-3, (2.02±0.16) ×10-3and (2.09±0.17) ×10-3mm2/s for right breast in the menstrual, proliferative and secretary phases. They were slightly higher than Group 3, which were (2.02±0.27) ×10-3, (1.97±0.25) ×10-3and (2.03±0.22)×10-3 mm2/s for left breast and (1.99±0.29) ×10-3, (1.93±0.26) ×10-3and (2.03±0.28)×10-3 mm2/s for right breast. The mean ADC values of Group 2 [left breast: (1.94±0.25) ×10-3, (1.91±0.21) ×10-3and (1.97±0.21)×10-3 mm2/s ; right breast: (1.97±0.26)×10-3, (1.89±0.25)×10-3and (1.96±0.22)×10-3 mm2/s) were the lowest among the three age groups. There were significant differences in different menstrual phases (F= 23.600, P＜0.01), but no statistical difference was found among the three age groups or between left breasts and right breasts (F= 1.683, 2.248;P＞0.05).Conclusions The mean ADC values of breasts decrease markedly in the proliferative phase.The effects of the menstrual cycle on the breast ADC values should be considered in the evaluation of breast diseases with DWI.

Objective:To conduct data mining on hospital accreditation results for inspirations and clues in hospital management.Methods:The Apriori function contained in the arules package of R software was used to extract the association rules. This practice aimed to analyze association rules of the accreditation results of 56 tertiary hospitals which were made based on tertiary hospital accreditation standard(2011)and Detailed Rules from 2017 to 2019; to explore the correlation between the clauses, and analyze the inspirations for hospital management.Results:A total of 6 566 138 and 247 rules were generated for all clauses and core clauses, receptively. The top 10 rules sorted by lift were selected as strong association rules. Among them, the minimum lift of all clauses and core clauses was 1.41 and 1.53, respectively. There was a strong correlation between the establishment of a quality and safety management team in the hospital and the development & implementation of relevant regulations by the hospital. There were strong correlations among emergency service procedure and regulations, patient rights to know, responsibility system by the first one to receive a complaint, medical safety(adverse)event reporting, development & implementation of antimicrobial management system, as well as training for prevention of multi-drug resistance infection measures, and multi-drug resistance infection hospital infection control system.Conclusions:This study suggested that hospital management should highlight the correlation between regulations development and staffing, that between indicator systems and monitoring feedback systems, and that between indicators in different sectors in the medical process. These correlations can be used as management clues and inspirations for hospital management.

Objective To explore the satisfaction of tertiary hospital employees, and to offer a basis for human resources management and decision-making improvement in hospitals.Methods The total area of China was divided into eastern, central and western areas by stratification sampling, and totally 15716 employees from 104 university hospitals and provincial hospitals in the three areas were selected by convenience sampling and investigated. This study was conducted online, and the time of sample return was from October 1st to November 30th, 2015. The employees were investigated for their satisfaction with the status of hospital management with the National Monitoring of Employees' Satisfaction Scale, which took into consideration such characteristics as position, sex, age, marital status, education, income, labor relations, working years and title.Results As for the position, the employees specialized in nursing showed the highest degree of satisfaction (91.10 points), while the employees working on medical positions had the lowest degree of satisfaction (85.34 points). Female employees had a higher degree of satisfaction than male ones, and married employees had a slightly lower degree of satisfaction than unmarried employees. Medical employees at different levels showed different degrees of satisfaction. Clinical front-line employees had lower satisfaction with their give and take than the employees on other positions.Conclusions The HR department of hospitals should pay attention to the employees' real concerns, and take measures to improve medical and nursing staffs' job satisfaction.

Objective:To characterize tibial plateau fractures using a computed-tomography-based "four-column and nine-segment" classification.Methods:A retrospective analysis was conducted of the 698 adult patients with tibial plateau fracture (704 knees) who had been admitted to Department of Orthopedics, The Affiliated People's Hospital of Jiangsu University from December 2007 to May 2018. They were 377 males and 321 females with an average age of 51.6 years. The left knee was affected in 371 cases (53.2%), the right knee in 321 cases (46.0%) and bilateral knees in 6 cases (0.9%). According to the differentiated morphological characteristics, the tibial plateau and proximal fibula were divided into 4 columns, which were subdivided into 9 segments. Tibial plateau injury index (TPII) was innovatively introduced to represent the extent of injury. Fracture mapping was retrospectively analyzed according to the "four-column and nine-segment" classification based on the CT imaging.Results:The rates of one-column, two-column, three-column and four-column injuries were 30.5% (215/704), 31.5% (222/704), 28.0% (197/704), and 9.9% (70/704), respectively. On average, 2.2 columns ± 1.0 columns and 3.6 segments ± 2.1 segments were affected in each case. The mean TPII was 5.7±3.0. The rates of mild, moderate and severe comminuted fractures were 50.0% (352/704), 37.5% (264/704), and 12.5% (88/704). The columns most frequently affected were the lateral column (572, 81.3%) and the intermedial column (524, 74.4%) while the less frequently involved ones the medial column (219, 31.1%) and the fibular column (218, 31.0%). The sequence of the segments affected was the posterolateral segment (465, 66.1%), the anterolateral segment (453, 64.3%), the posteromedian segment (379, 53.8%) and the tubercle segment (85, 12.1%).Conclusions:The novel "four-column and nine-segment" classification may be a beneficial system for clinical diagnosis, statistical analysis and prognostic judgment of tibial plateau fractures.

In order to explore the effects of Coptis detoxification powder on immune suppression and inflammatory response caused by heat stress in animals,Bama pigs were used as experimental animals to establish an animal model of heat stress,and the effects of Coptis detoxification powder on transcriptional activation of TLRs mRNA in PBMC induced by heat stress and its mediated ex-pression of inflammatory factors were studied in vivo.The animal model of heat stress was estab-lished by artificial climate greenhouse,Chinese medicine"Coptis detoxification powder"was pre-pared,and its inhibitory effect on heat stress and inflammation was studied by preventive and therapeutic administration.Real-time fluorescence quantitative PCR was used to determine the transcriptional changes of HSP70,TLRs and IL-17 mRNA,and ELISA was used to determine the dynamic changes of serum IL-2,IL-6 and TNF-α.Western blot and indirect immunofluorescence(IFA)were used to determine the nuclear translocation and protein expression of p65 phosphoryl-ated protein in NF-κβ inflammatory factor pathway.The transcription of PBMC TLRs mRNA and its mediated inflammatory factor expression and function in Bama pigs under heat stress were sys-tematically analyzed.The results showed that the experimental animal model of Bama pigs under heat stress was successfully established,and heat stress significantly up-regulated the mRNA tran-scription levels of HSP70,TLR2,TLR4 and inflammatory factor IL-17,resulting in significantly enhanced expressions of serum inflammatory factors IL-2,IL-6 and TNF-α.The NF-κβ pathway significantly promoted the level of p65 nuclear phosphorylation and the expression of cytoplasmic protein.The Chinese medicine"Coptis detoxification powder"could significantly reduce the upreg-ulation effect of heat stress conditions on the transcription levels of HSP70 and TLRs mRNA,thus inhibiting the mRNA transcription of inflammatory factor IL-17 and the expression of IL-2,IL-6 and TNF-α in serum,and significantly antagonizing the transcriptional activity of NF-κβ caused by heat stress.It showed good anti-heat stress effect.The anti-inflammatory effects of Chinese veteri-nary medicine prescription"Coptis detoxification powder",its pathway of action and its effectors were investigated,the expression and secretion levels of the regulatory factors related to the path-way associated with TLRs mRNA inhibition were analyzed,and the functional effects and mecha-nism of its clinical anti-heat stress and anti-inflammatory effects were clarified,which laid a data foundation for the promotion and application of this prescription and related mechanism research.
