Objective To investigate the effects of different doses of oxycodone on postoperative pain and stress response in patients undergoing gynecological laparoscopic surgery. Methods Sixty patients scheduled for gynecological laparoscopy,aging from 18 to 50 years old,of ASA Ⅰ or Ⅱ,were included and randomized into three groups:control group (group C),low dose of oxycodone group (group L),high dose of oxycodone group (group H),20 cases in each group.Pa-tients in group L,H received 0.05,0.1 mg/kg oxycodone respectively while paitents in group C re-ceived saline 5 ml 1 5 min before the end of the surgery.Visual analogue scale(VAS)pain score and RASS score were measured on 1,6,12 and 24 h postoperatively.Glucose and serum cortisol were also measured before the operation and on time points of 6,12 and 24 h after the operation.Adverse effects were recorded too.Results Compared with group C,VAS were significantly lower in group L and H within 1 hour postoperatively.(P <0.05).VAS was significantly lower in group H than that in group C and L at 6 h postoperatively (P <0.05 ).The RASS scores of group L and H were significantly lower than those in group C (P <0.05)at 1 h postoperatively.Blood glucose and serum cortisol of group L and H increased at 6,12 and 24 h after operation (P <0.05).Compared with group C,blood glucose and serum cortisol were significantly lower in group L and group H at 6,12 h after operation (P <0.05).There was no significant difference in the incidence of adverse reactions in each group. Conclusion Oxycodone 0.1 mg/kg injected before the end of gynecological laparoscopic surgery could effectively relieve postoperative pain with less adverse reactions,and decrease postoperation stress re-sponse.

Objective: To investigate the relationship between personality characteristics and turnover intention of the medical staff in an infectious diseases hospital. Methods: Using the cluster sampling method, a total of 366 members of medical staff were selected from different departments in an infectious disease hospital from May to August, 2013. The general information, such as sex, age, education level, and professional title, were collected and they were subjected to a survey using Cattell’s 16 Personality Factor Questionnaire and Turnover Intention Scale. The data were subjected to logistic regression analysis. Results: Compared with the Chinese norm, the medical staff in the infectious disease hospital had significantly higher scores of intelligence, stability, bullying, excitability, perseverance, social boldness, fantasy, privateness, independence, and self-discipline and significantly lower scores of gregariousness, sensitivity, suspicion, anxiety, and tension (P<0.05). Of the 366 members of medical staff, 22 (6.01%) had a very low turnover intention, low in 152 (41.53%) , high in 61 (16.67%) , and very high in 131 (35.79%). The logistic regression analysis showed that sensitivity, suspicion, fantasy, privateness, anxiety, openness to change, and independence were the risk factors for turnover intention (P<0.05) . Conclusion Compared with the Chinese norm, the medical staff in the infectious disease hospital have a better mental quality and a higher turnover intention. The individuals with sensitivity, suspicion, fantasy, and anxiety are prone to having turnover intention.

Objective To investigate the differential expression of microRNA (miRNA) in schizophrenia (SZ) patients,and explore the comorbidity of SZ and depression disorder based upon miRNA expression.Methods Affymetrix array analysis was used to investigate the differentially expressed miRNA in SZ patients firstly,and then quantitative real-time polymerase chain reaction (qRT-PCR) was further carried out to confirm the selected miRNA in peripheral blood mononuclear cells of 40 SZ patients,whom were administered by Positive and Negative Syndrome Scale (PANSS) and the selected miRNAs in depression disorder patients has also been confirmed by Affymetrix array analysis and qRT-PCR in our previous studies.Results Affymetrix array analysis indicated that there existed 33 miRNAs which differentially expressed (32 up-regulated and 1 down-regulated) compared with normal controls.qRT-PCR results suggested that the expression of 8 miRNAs (miR-1273d,miR-1303,miR-3064-5p,miR3131,miR-3687,miR-4428,miR-4725-3p and miR-5096) were significantly up-regulated in SZ;the miRNA differentially expressed in depression disorder patients also had differential expression in SZ patients (P＜0.05).There were significant correlation between the miRNAs differentially expressed in depression disorder patients and in SZ patients (P＜0.01).MiR-1972 differentially expressed in depression disorder patients had significant positive correlation with the positive symptoms of PANSS (P＜0.05),and miR-26b was positively correlated with composite factor (P＜0.05).Conclusion Comorbidity of SZ and depression disorder is observed not only on the clinical symptoms,but on the molecular genetic basis.

Objective To analyze the monitoring results of iodine deficiency disorders (IDD) of Dehong State in 2017,to find out the present situation of prevention and control of IDD,and to provide scientific basis for guiding the comprehensive prevention and control of IDD in our state in the future.Methods According to "Yunnan Iodine Deficiency Disorders Monitoring Program",a sampling survey was conducted in 5 counties (cities) of Dehong State,Yunnan Province.Urine and household salt samples were collected from children aged 8 to 10 years old and pregnant women in Mangshi,Lianghe County and Yingjiang County.Iodine content was detected.In addition,household salt samples of Ruili City and Longchuan County were collected to detect iodine content.Results There were 1 609 salt samples from local inhabitants,the coverage rate of iodized salt was 99.19％ (1 596/1 609),the edible rate of qualified iodized salt was 95.03％ (1 529/1 609) and the median of iodized salt was 23.76 mg/kg.The median of urinary iodine in 623 children aged 8 to 10 years old was 221.34 μg/L and the thyroid enlargement rate was 0.48％ (3/623).The median of urinary iodine in 346 pregnant women was 159.52 μg/L.Conclusion The iodine nutrition of children aged 8 to 10 years old and pregnant women of Dehong State is appropriate in 2017.

OBJECTIVE: To establish a deep-learning architecture based on faster region-based convolutional neural networks (Faster R-CNN) algorithm for detection and sorting of red ginseng (Ginseng Radix et Rhizoma Rubra) with internal defects automatically on an online X-ray machine vision system. METHODS: A Faster R-CNN based classifier was trained with around 20 000 samples with mean average precision value (mAP) of 0.95. A traditional image processing method based on feedforward neural network (FNN) obtained a bad performance with the accuracy, recall and specificity of 69.0%, 68.0%, and 70.0%, respectively. Therefore, the Faster R-CNN model was saved to evaluate the model performance on the defective red ginseng online sorting system. RESULTS: An independent set of 2 000 red ginsengs were used to validate the performance of the Faster R-CNN based online sorting system in three parallel tests, achieving accuracy of 95.8%, 95.2% and 96.2%, respectively. CONCLUSION The overall results indicated that the proposed Faster R-CNN based classification model has great potential for non-destructive detection of red ginseng with internal defects.
