ABSTRACT
OBJECTIVE@#To investigate the influencing factors on prognosis of adult patients with chronic primary immune thrombocytopeuia (ITP) after rituximab treatment and predictive value of platelet (Plt) count.@*METHODS@#Clinical data of 52 adult patients with chronic primary ITP treated with rituximab from January 2012 to December 2016 were retrospectively analyzed, including 32 patients for failed in treatment as group A and 20 patients for succeeded in treatment as group B. The independent risk factors influencing the clinical efficacy of rituximab were analyzed. The influence of CD41 megakaryocyte count in bone marrow diagnosed for first time on the response rate of patients with 1-year followed-up were observed, and the Plt count were calculated to predict the clinical efficacy index and the best cut-off point.@*RESULTS@#The CD41 megakaryocyte count in bone marrow for first time treatment in group B were significantly higher than that in group A (P＜0.05). Multivariate Logistic regression analysis showed that the number of CD41 megakaryocytes in bone marrow＜150 at first diagnosis was the independent risk factor influencing the clinical efficacy of rituximab (OR=5.40，95%CI：1.82-15.66，P=0.00). The response rate of 1-year followed-up in patients with CD41 megakaryocyte count ≥150 at first diagnosis was significantly higher than that of CD41 megakaryocyte count ＜150 (P＜0.05). The Plt count level in group B was significantly lower than that in group A at the 3rd, 14th, 21th, 30th, 60th, 90th, 180th, 270th and 360th days after first treatment with rituximab (P＜0.05). ROC curve analysis showed that the best cut-off point for Plt count was 50×10/L and AUC was 0.68 at the 14th day after first treatment with rituximab (95%CI: 0.57-0.78, P=0.00). The predictive sensitivity and specificity of clinical efficacy in adult patients with chronic primary ITP treated with rituximab were separately 48.73% and 87.58%, and the AUC in 30th and 60th day after rituximab treatment were separately 0.74 (95%CI: 0.64-0.87, P=0.00), 0.93 (95%CI：0.82-0.98，P=0.00).@*CONCLUSION@#Adult patients with chronic primary ITP may possess long-term remission after rituximab treatment, but the prognosis is poor for patients with bone marrow megakaryocyte count ＜150. The Plt counts in 14th, 30th and 60th days after rituximab treatment can effectively predict the long-term clinical efficacy and guide the formulation of treatment plans.

Based on the outpatient interview and literature review,the initial framework of the outpatient experience of human caring scale was formed with 9 dimensions of outpatient process.The research aim was to improve the scale by Delphi method.Sixteen experts in medical management,human caring or medical education were invited to evaluate the importance of the dimensions and items of the scale and provided some expertise via filling out the Delphi consultation questionnaires twice in the consulting round.In the first round,the recovery rate showing the experts' positivity was 80％;the coefficient of reliability (Cr) ascertaining the authority of the evaluation was 0.92;the mean and full mark ratios responding the concentration of the evaluation were 2.88-4.94 and 6.25％-93.75％ respectively;the coefficients of variation (CV) and the Kendall's W determining the concordance of the evaluation were 5.06％-52.15％ and 0.21-0.24 respectively.In the second round,the recovery rate was 93.75％;the Cr was 0.93;the mean was 3.93-4.93;the full mark ratios were 26.67％-93.33％;the Kendall's W was 0.14-0.31,the CV was 5.25％-23.61％.Via the two-round Delphi study,the scale that included 10 dimensions and 61 items has been improved.Ten dimensions are pre-hospital medical service,guidance,registration,waiting,diagnosis & treatment,paying,inspection & assay,medicine receiving,therapy/injection/transfusion and global evaluation.It was concluded that Chinese scholars have paid high attention to human caring and outpatient experience.The experts have given high agreements about the dimensions which were established with Chinese outpatient process.The dimensions are different from the similar researches about outpatient experience study.In the future,it is necessary to survey the outpatients to test the construct validity,internal consistency reliability and others of the scale to improve the scale.

ABSTRACT
The risk factors and precautions of inpatient suicide were explored. Thirty suicide victims were drawn from the adverse event reports of suicidal act during hospitalization in a general hospital from 2008 to 2014. Data were gathered from the focus group interviews of twelve nurses who had experienced inpatient suicide. The data were analyzed by using analytical technique based on grounded theory, and software QSR NVIVO8 was used to aid the collation of data. Three main themes of risk factors about inpatient suicide emerged from the analysis: individual value, social factors and environmental factors. The individual value was categorized into different groups such as sense of guilt, hopelessness and low self-esteem. Social factors included two aspects of negative life events and social support. Three themes of precautions about inpatient suicide appeared in this study: evaluation, nursing and information exchange. Evaluation was elaborated from both physical and psychological assessments. This finding extends existing work of risk factors and precautions about inpatient suicide and brings new knowledge about the reasons why inpatients commit suicide.
ABSTRACT
Maca (Lepidium meyenii) is an herbaceous plant that grows in high plateaus and has been used as both food and folk medicine for centuries because of its benefits to human health. In the present study, ITS (internal transcribed spacer) sequences of forty-three maca samples, collected from different regions or vendors, were amplified and analyzed. The ITS sequences of nineteen potential adulterants of maca were also collected and analyzed. The results indicated that the ITS sequence of maca was consistent in all samples and unique when compared with its adulterants. Therefore, this DNA-barcoding approach based on the ITS sequence can be used for the molecular identification of maca and its adulterants.
