Objective To investigate the influence of the pain management path on the postherpetic neuralgia patients. Methods Ninety patients with postherpetic neuralgia were divided into two groups by random digits table method:the control group and the experimental group, 45 cases in each group. The patients in the control group accepted conventional nursing care, the patients in the experimental group accepted the pain management path nursing care. The scores of pain and the overall satisfaction were assessed, the incidence of common adverse reactions at 5 and 10 days after the treatment, hospitalization expenses and hospitalization days were recorded. Results The gender, age, course of disease and degree of pain had no significant difference between the experimental group and the control group at admission (P>0.05). After 5 and 10 days treatment, the scores of pain in the experimental group were (3.07±1.34) , (1.09±0.90) points, and these were (4.29±1.74), (2.27±1.32) points in the control group, the differences were statistically significant (t=3.74, 4.94, all P<0.01). After 5 and 10 days treatment, the scores of the overall satisfaction in the experimental group were (5.50 ± 1.71), (7.96 ± 1.30) points, and these were (4.50 ± 1.60), (7.00 ± 1.50) points in the control group, the differences were statistically significant (t=-2.89,-3.37, all P<0.01). After 10 days treatment, the incidence of constipation was 26.67% (12/45) and 53.33% (24/45) in the experimental group and the control group respectively, the difference was statistically significant between the two groups (χ2=6.667, P<0.05). The hospitalization days were (13.71 ± 3.05) d and (15.76 ± 3.54) d in the experimental group and the control group respectively, the difference was statistically significant between the two groups (t=2.934, P<0.01). The hospitalization expenses were (11798.38 ± 3312.33) yuan and (13972.24 ± 3726.66) yuan respectively, there was significant difference between the two groups (t=2.925, P < 0.01). Conclusions The application of the pain management path for the pain management in patients with postherpetic neuralgia, can relieve the pain, reduce the incidence of adverse effects, hospitalization expenses and days, improve the overall satisfaction of the patients.

Objective:To explore the gene-body mass index (BMI) interaction on coronary heart disease (CHD) in the Chinese adult twins.Methods:A total of 20 340 same-sex twin pairs registered in the Chinese National Twin Registry (CNTR) were enrolled in this study. Classical twin structure equation model was used to estimate the gene-BMI interaction on CHD.Results:After adjusting for age, we found that genetic variance of CHD differed as the function of BMI in male twins, which indicated the presence of a gene-BMI interaction on CHD ( P=0.008).The genetic moderating effect ( βa) was -0.14 (95% CI: -0.22--0.04), indicating that for each logarithmic transformation value of BMI increase, genetic path parameters would decrease by 0.14, which would result in the decrease of genetic variance of CHD. And the heritability of CHD was 0.77 (95% CI: 0.65-0.86) among the male twins with lower BMI (<24.0 kg/m 2), but 0.56 (95% CI: 0.33-0.74) among the male twins with high BMI (≥24.0 kg/m 2). However, there was no evidence suggesting that BMI could moderate genetic variants of CHD in female. Conclusion:We found a significant gene-BMI interaction on CHD in the Chinese male adult twins in China, and the heritability of CHD was higher among the twins whose BMI was <24.0 kg/m 2.
