Background Reliable intraocular pressure (IOP) measurement is essential in glaucomatous study.TonoLab is a newly designed tonometer for small animals,however,its repeatability and reproducibility remains unknown.Objective This study aimed to evaluate the repeatability and reproducibility of TonoLab rebound tonometer in DBA/2J mice.Methods Intraocular pressure was measured in both eyes of 63 DBA/2J mice aged 7 months under systemic anesthesia with TonoLab rebound tonometer.IOP of each eye was measured for 3 times by two observers independently and consecutively using TonoLab rebound tonometer,and the data were obtained in single blind method.Within standard deviation (Sw),interclass correlation coefficient (ICC),within coefficient of variation (CVw) and corresponding 95% confidence interval (CI) were calculated to evaluate the repeatability of measuring result from single observer,and Bland-Altman method was used to assess the agreement between two observers.The abnormal data which affected repeatability was analyzed.Results Among the 126 eyes,105 eyes showed the normal IOP with mean value (12.98 ± 1.05) mmHg from observer 1 and (12.41 ±0.92) mmHg from observer 2.Ocular hypertension was found in 21 eyes with mean value (27.76 ± 1.95) mmHg and (27.49 ± 1.28) mmHg for observer 1 and observer 2 respectively.Sw,ICC and CVw for observer 1/observer 2 were 1.34/1.11 mmHg,0.90/0.92,8.24%/7.42% in normal eyes and 2.21/1.49 mmHg,0.89/0.95,6.97%/4.82% in hypertensive eyes.The average bias between two measuring values from different observers was 0.60 mmHg in the normal eyes (95% CI:-5.20-6.30 mmHg) and 0.30 mmHg in the hypertensive eyes (95% CI:-7.30-7.80 mmHg).Conclusions TonoLab rebound tonometer can offer a good intraobserver repeatability in both normal and hypertensive eyes in mice,but the agreement between two observers is outside an acceptable level.So we consider IOP in mice obtained by TonoLab rebound tonometer is reliable and accurate from a single observer.

Objective:To study the effect of totally endoscopic surgery and Miccoli surgery for papillary thyroid microcarcinoma. Methods Totally 64 patients with papillary thyroid microcarcinoma from April 2013 to April 2014 in our hospital were divided into the ob-servation group and the control group according to a random number table.And the intraoperative and postoperative situation of the two groups were compared.Results The number of lymph node dissection,postoperative hospital stay,hospital costs of the two groups had no sig-nificant difference (P >0.05).The blood loss,operative time,drainage time,amount of drainage,incision length,time of postoperative recov-ery of the observation group were significantly less than those of the control group with statistical significance (P <0.05).But the cosmetic score of observation group after operation was lower than that of the control group,and there was a significant difference (P <0.05).Postop-erative pain grade of the observation group was better than the control group with statistical significance (P <0.05).The complication rate of control group was significantly higher than the observation group (P <0.05).Conclusion Miccoli surgery for papillary thyroid microcarci-noma has more advantages compared with totally endoscopic surgery in terms of blood loss,operative time,drainage time,amount of drainage, incision length,time of postoperative recovery,and degree of pain.Moreover,it has a lower complication rate and high security,which should be the first choice in clinic surgery.

Objective To explore the factors influencing the sitting early away from bed after operation in elderly patients having hip fractures.Method Forty-six elderly patients with hip fractures who were taking postoperative functional exercises of sitting away from bed and 32 nurses were investigated on the influential factors by a questionnaire.Results More than 52.1%of the patients believed the factors influencing their sitting early away from bed including lack of family support,worry about insufficient physical strength and fear of pains.65.6%of the nurses thought the factor was their inadequate assessment.Conclusion Such measures as enhancing family support,nutritional support,relief of pains from sitting from bed and improving nurse’s ability in rehabilitative training instruction are important for the patients to sit early away from bed after operation on hip fractures.

Objective This study investigated the differences between axillary temperature monitored for 5min and 10min with mercury in glass thermometers. Methods A sample of 365 patients had axillary temperatures monitored for five minutes and ten minutes, Relevant research data were analyzed by meta analysis. Results At α=0.05 level, the result of paired t test between 5 minutes and 10 minutes temperature indicated that there was statistical difference, Meta analysis had the same result, Temperaturedata of 365 patients were expressed in the Bland-Altman plot which displayed that their consistency can not be accepted in the professional. Conclusions The optimal axillary mercury thermometer placement time for recording human body temperature is 10 minutes.

Objective To investigate the compliance of evidence-based nursing on post-operative elders with hip fracture sitting at early stage. Methods A total of 108 post-operative elders with hip fracture were divided into the observation group and the control group with 54 cases in each group with random digit table. The patients in the control group sit from bed based on their state of vital signs and mental status on the 2nd or 3rd postoperative day. And those in the observation group employ evidence-based nursing on the basis of the control group. The degree of anxiety, postoperative fatigue and compliance of patients were compared. Results Two weeks after the operation, the degree of anxiety scored 40.96±5.13, postoperative fatigue scored 1.89±0.65 in the observation group, which were lower than those of the control group, 56.40±4.28, 4.55±0.71, the difference was significant (t=288.41, 412.35, both P<0.01). The rate of compliance in the observation group was 94.44% (51/54), and the rate of the control group was 77.77%(42/54). The rate of compliance in the observation group was higher than that of the control group(χ2=8.57, P<0.05). Conclusions Using evidence-based nursing on post-operative elders with hip fracture sitting at early stage is able to improve the compliance of patients. It is good for reducing the postoperative complications, improving activities of daily life and mental state, promoting rehabilitation in patients as well.

Objective To explore the inner feelings of gestational diabetes at their primary use of the real-time blood glucose monitoring. Method Using the qualitative method, 10 gestational diabetic patients monitored their blood glucose using the real-time blood glucose monitoring for the first time and then were interviewed, the acquired results treated with phenomenological analysis. Result The inner feelings of the 10 patients were summarized including 5 themes:worry about the safety of the fetus, fear on alarming at monitoring, different views on four times input of finger blood glucose values, worry about inaccuracy in blood glucose monitoring data, changes in mental conditions and diets. Conclusion Health care workers should provide the gestational diabetic patients with targeted care strategies based on presence of psychological status and knowledge needs so as to improve their compliance, reduce the psychological burden of patients and control their blood glucose level.

AIM: To establish identification and determination methods for aristolochic acids. METHODS: The extracts of the sample were developed on silica gel G F254 plate, using supernatant layer of the mixture of toluene-ethyl acetate-water-formic acid (20 ∶10 ∶1 ∶1) as the mobile phase. Chromatogram system:gradient elution with mobile phase consisting of (A) 1% acetic acid in water and (B) methanol was used. The initial condition was at 40% of B and gradient up to 100% B in 15 minutes before returning to the initial conditions. Detection was at 310 nm. The column temperature was set at 40℃ and flow-rate was set at 1.0 mL/min. RESULTS: TLC:the Rf value of aristolochic acid Ⅰ was 0.50 and aristolochic acid Ⅱ was 0.53. The results of assay were shown as follow: The average recovery of aristolochic acid Ⅰ was 103.3% (RSD=0.98%). The average recovery of aristolochic acid Ⅱ was 95.97% (RSD=1.2%). CONCLUSION: It reveals that the methods we described are accurate, rapid and reproducible.
