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 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.

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.

Rhei Rhizoma is a Chinese medicine with multiple botanical origins. There is a problem to identify it with conventional methods. To compare the characteristics of chloroplast matK gene sequences of different Rheum species and authenticate inspected species, the matK gene sequences of different species from different origins were amplified, cloned, and sequenced. Genomic DNA of Rheum plants was extracted using modified DNA extracted Kit and matK gene sequences were analyzed by ContingExpress, DNAman and MEGA5.0. The length of matK gene sequences of Rheum palmatum, R. tanguticum and R. officinale were 1 518 bp containing 57 variable loci. According to the mutation sites, R. palmatum, R. tanguticum and R. officinale were divided into different genotypes separately. Based on the established method according to the loci 587, 707, 838, we successfully identified the genuine Rheum species from its adulterants.
