Objective To investigate the effect of competitive N-methyl-D-aspartate (NMDA) receptor antagonist LY274614 [(?)-6-phosphonomethyl-decahydroisoquinolin-3-carboxylic acid] on the development of morphine tolerance and dependence.Methods Male Spraque-Dawley rats were rendered tolerant and dependent by subcutaneous injection of morphine(15mg/kg body weight) three times a day for 10 consecutive days. LY274614 (2, 4, 6 mg/kg body weight) was also given subcutaneously by subcutaneous injection. Antinociception was measured by tail-flick (TF) test. Tail was exposed to the heat source(a beam of high intensity light). The time from the beginning of exposure to removal of tail from the path of the heat source was taken as latency. The baseline TF latency without medication was 4-5 seconds. A ten-second maximum exposure to the heat source was used to minimize damage to tissue during the multiple measurements. Morphine prolonged TF latency. With the development of tolerance TF latency gradually returned to baseline value. Physical dependence on morphine was assessed by abstinence syndrome precipitated by subcutaneous injecting naloxone 10 mg/kg on the tenth day. According to method of Blasig, the number of jumping/30min after naloxone injection was recorded as an index pf abstinence syndrome. Rats were randomly divided into 8 groups (n=6-8). Each group received morphine 15 mg/kg or normal saline (NS) 1.5 ml/kg+LY274614 (2.0,4.0,6.0 mg/kg) or NS, group 1: morphine+NS; group 2: NS+NS; group 3:morphine+LY274614 (2mg/kg); group 4: NS+LY274614 (2mg/kg); group 5: morphine+LY274614 (4mg/kg); group 6: NS+LY274614 (4mg/kg); group 7: morphine+LY274614 (6mg/kg); group 4: NS+LY274614 (6mg/kg).Results LY274614 itself did not have analgesic action, but if used with morphine, it did inhibit the development of tolerance. In group 5 and 7 the decrease in TF latency was more gradual than that in morphine+saline group. 4 and 6 mg/kg LY274614 reduced the number of jumping/30min following naloxone injection.Conclusions LY274614 can inhibit morphine tolerance and dependence rendered by consecutive subcutaneous morphine injection.

Objective To investigate the coping mode and quality of life of patients with malignant glioma during chemotherapy.Methods European organization for research and treatment of cancer quality of life,Core 30(EORTC QLQ-C30) and medical coping modes questionnaire(MC-MQ)were used for the survey among 45 patients with malignant glioma during chemotherapy.Results The scores on patients' emotion function and role function were(7.80±2.52)and(16.26±5.35),both at a low level.The avoidance factor in copy mode was scored(16.26±5.35),significantly lower than the norm(14.44±2.97)(P<0.05). Conclusion Nurses should make pertinent measures for intervention,encouraging patients to take right cope mode and keeping positive attitude so as to improve their quality of life.

Objective To investigate health beliefs and fluid status in diabetic peritoneal dialysis patients, to explore the relation between fluid status and health beliefs in diabetic peritoneal dialysis patients. Methods The data were collected from the peritoneal dialysis center in Ningxia Medical University General Hospital from January 2014 through January 2015. A total of 64 diabetic peritoneal dialysis patients were recruited and investigated with health beliefs scale, fluid status and laboratory index, the influencing factors were analyzed with Logistic regression. Results Levels of perceived barriers in diabetic peritoneal dialysis patients was the lowest. The score of perceived barriers, levels of albumin and daily water intake in pedal edema diabetic peritoneal dialysis patients were 35.34±10.31, (29.90±4.51) g/L,(860.34±516.71) ml/d, and the results in the non-pedal edema patients were 31.67±12.47, (32.72±6.87) g/L, (872.22±271.85) ml/d, the difference was significant (t=-1.99,2.09,-3.07, P<0.05 or 0.01). Perceived barriers in diabetic peritoneal dialysis patients was positively correlated with edematous level (r=0.16,P<0.05) and perceived capacity balancing was negatively correlated with edematous level (r=-0.25,P<0.05). Regression analysis showed that marital status,dialysis age,daily water intake and perceived barriers were the main factors influencing fluid control in diabetic peritoneal dialysis patients. Conclusions Fluid control in diabetic peritoneal dialysis patients is affected by their health beliefs, this indicates that diabetic peritoneal dialysis patients must have insufficient awareness of fluid status and fluid adherence. It is suggested that they should establish comprehensive health beliefs.

Objective Based on the theory of preventive treatment and constitution regulation, to observe the clinical efficacy of point application for stable chronic obstructive pulmonary disease (COPD).Methods Seventy-nine qi deficiency or yang deficiency patients in stable COPD were randomized into a treatment group of 40 cases and a control group of 39 cases. The control group received conventional medication and the treatment group additionally received point application in canicular days or the three-nine days in winter. The frequency of catching cold, the situation of acute exacerbation of chronic obstructive pulmonary disease (AECOPD), constitution types and scores of traditional Chinese medicine (TCM), pulmonary function [the level of forced expiratory volume in one second (FEV1), the percentage of FEV1 in predicted value, FEV1’s ratio to forced vital capacity (FVC)], BODE index (body mass index, airflow obstruction, dyspnea and exercise capacity index) and therapeutic effects were recorded in the two groups before and after the treatment. The correlation analysis was performed between the scores of constitution and the frequency of catching cold, AECOPD, syndrome scores of TCM, BODE index.Results The cold times, AECOPD attack times, times of hospitalization for AECOPD and syndrome scores of TCM were significantly changed in the treatment group after treatment (P<0.01,P<0.05). There were statistically significant changes in the cold times, AECOPD attack times, and syndrome scores of TCM in the two groups after treatment (P<0.05). The total effective rate was 85.7% in the treatment group versus 70.3% in the control group, and the difference was statistically significant (P<0.05). The scores of the main abnormal constitution (qi deficiency or yang deficiency) and balanced constitution were significantly changed in the treatment group after treatment (P<0.01,P<0.05). There were statistically significant differences in the scores of the main abnormal constitution and balanced constitution between the two groups after treatment (P<0.01,P<0.05). There were no statistically significant changes in each item of pulmonary function in the two groups after treatment (P>0.05). After the treatment, the change of the BODE score in the treatment group was significantly different from that in the control group (P<0.01). A significant positive correlation was found between the main abnormal constitution scores and the cold times, AECOPD attack times, times of hospitalization for AECOPD, syndrome scores of TCM in the treatment group after treatment (P<0.05,P<0.01). A significant negative correlation was found between the balanced constitution scores and the cold times, AECOPD attack times, times of hospitalization for AECOPD, syndrome scores of TCM in the treatment group after treatment (P<0.05,P<0.01).Conclusion Point application is an effective method for stable COPD.

Background Small incision lenticule extraction (SMILE) is lack of eye-tracking system and there is controversy in the treatment of astigmatism.It is very important to understand its correction effctiveness for myopic astigmatism.Objective This study was to evaluate the clinical outcomes in the correction of myopic astigmatism between SMILE and femtosecond laser assisted laser in situ keratomileusis (FS-LASIK).Methods In this retrospective study,95 eyes of 51 patients and 69 eyes of 40 patients with myopic astigmatism underwent the SMILE surgery and FS-LASIK surgery respectively in Tianjin Eye Hospital from December 2013 to July 2014 under the informed consent.No significant differences were found in spherical power,astigmatic power and spherical equivalent (SE) between the SMILE group and FS-LASIK group before surgery (all at P＞0.05).The uncorrected visual acuity (UCVA),best corrected visual acuity (BCVA),manifest refraction,slit-lamp microscopy,intraocular pressure and corneal topography were measured before surgery and 1 day,1 week,1 month,3 months after surgery.Vector analysis was used to calculate the components of astigmatism before and after surgery.Correction index (CI),index of success (IOS),angle of error (AofE) and flattening index (FI) were used to evaluate the correction effectiveness of astigmatism.Safety index and efficacy index were used to evaluate the recovery status of visual acuity.The corrected effectiveness was compared between the two groups,and the correlations of kappa angle with measured parameter were assessed by Spearman rank correlation analysis.Results The mean spherical power,astigmatic power and SE were (0.003±0.106),(-0.063 ± 0.126) and (-0.029 ± 0.101) D in the SMILE group,which were significantly lower than (0.112 ± 0.212),(-0.091 ± 0.142) and (0.067 ± 0.198)D in the FS-LASIK group (Z =-4.328,-3.197,both at P＜0.05).Vector analysis showed the postoperative with-the-rule astigmatism in the SMILE group and oblique astigmatism in the FS-LASIK group respectively,and the CI and F1 in the SMILE group were significantly lower than those in the FS-LASIK group (Z =-3.051,-3.126,both at P ＜ 0.05).The insignificant reduce in IOS and AofE were seen in the SMILE group compared with the FS-LASIK group (Z=-1.557,P=0.119;Z =-1.923,P =0.054).In addition,the safety index and efficacy index were not significantly different between the two groups (both at P ＞ 0.05).Negative correlations were found between safety index or efficacy index and preoperative kappa angle in the SMILE group (r =-0.258,-0.257,both at P＜0.05).Conclusions Both SMILE and FS-LASIK surgeries are effective and safe in correcting myopic astigmatism with good postoperative visual acuity.SMILE surgery shows less axis rotation and higher accuracy than FS-LASIK because of small incision and flapless procedure.The correction of cylinder can adjust based on experience of surgeon.

Background The use of adaptive optics (AO) system in ophthalmic clinic and basic studies has increased in recent years.However,there are few reports on the stability of ocular aberrations after correction.Objective This study was to analyze the stability of aberration after correction by observing the repeatability of ocular aberration measurements.Methods Forty-one postgraduate school students and volunteers who meet the conditions were included from February to April 2014.The Zernike aberration coefficients including astigmatism (Z2-2,Z22),defocus (Z02),trefoil (Z33,Z3-3),coma (Z3-1,Z13),spherical aberration (Z40) and the value of root mean square (RMS) including 3rd-order to 7th-order aberrations,total higher-order aberrations (HOAs) and total ocular aberrations (TOAs) were measured by using AO system.The repeatability and stability of these data after corrected with AO system were analyzed.The repeatability was evaluated by ANOVA,within-subject standard deviation (Sw),repeatability (r) and intra-class correlation coefficients (ICC).The stability was evaluated by the nonparametric Friedman's rank test.Results AO system showed excellent repeatability on Z2-2,Z22,Z20 and TOA RMS (ICC＞ 0.9),good repeatability on Z13,Z33,Z3-3,Z40,3rd-order RMS,4th-order RMS,HOA RMS (ICC ＞ 0.75),poor repeatability on Z3-1,5th-order RMS,6th-order RMS,7th-order RMS (ICC ＜ 0.75).Repeatability (2.77 Sw) values ranged from 0.009 mm (7th-order RMS) to 0.163 mm (Z31).After low-order ocular aberrations were corrected,It was founded that Z2-2,Z22 reached stable state at the 4th second;Z02 was stable at the 6th second;Z3-3 and Z33 reached stable state at the 4th second and third second,separately;Z13 was stable from 3rd-second to 9th-second,Z3-1 was stable at the 4th-second.Z40 and HOA RMS were stable at the third second and fifth second,respectively.The Z2-2,Z02,Z22,Z3-3,Z3-1,Z33,Z40 and HOA RMS were significantly different among different time points before and after low-order aberrations correction (all at P ＜ 0.05).Z2-2,Z22,Z20 reached stable state at the 4th-second,3rd-second and 5th-second,respectively;Z3-3,Z33 reached stable state at the 2nd-second and 3rd-second,respectively;Z3-1and Z40 reached stable state at the 2nd-second;HOA RMS reached stable state at the 5th-second.Conclusions After correcting the human ocular aberration,different aberrations can reach stable state at different time.The time of Z02,Z22,Z3-3,Z3-1,Z40reaching stable state after 2nd-order to 5th-order ocular aberrations correction was earlier than those of lower-order aberrations correction.
