Objective To describe the patients′satisfaction with multimodal analgesia management after total knee arthroplasty. Methods 110 patients with total knee arthroplasty selected from February 2013 to February 2014 were recruited to complete a questionnaire, which was composed of the Visual Analogue Scale (VAS) , the Houston Pain Outcome Instrument (HPOI), and the Scale of Perceptions of Patients′Pain. Results VAS scores at different times were ranged from (2.14±1.21) points to (1.19±0.62) points, mean rating for general satisfaction with pain management was 80.04% (136.06/170.00), satisfaction with education on pain control was only 63.20% (37.92/60.00). Patients with different age and educational level of satisfaction with pain control had significant differences (P<0.05). Patients who thought relieving pain was harmful was 56.4% (62/110), the patients who did not understand the impact of pain on the body was 62.7% (69/110), the patients who did not understand the common methods of analgesia was 59.1%(65/110), the patients who did not understand the adverse reactions of pain measures was 63.6% (70/110). Conclusions Patients′satisfaction with the analgesic effect of multimodal analgesia is higher after total knee arthroplasty, while satisfaction with education on pain control was lower. Nurses should strengthen health education to patients with total knee arthroplasty about knowledgement of multimodal analgesia.

Objective: To describe the differences of plasma folate concentration and prevalence of folate deficiency in genders and ages in Chinese adults aged 35 to 64 years. Methods: By cross-sectional analysis, plasma folate concentration was measured in 2 545 adults including men and women by microbiological assay. Results: (1) Men tended to have lower plasma folate concentration and higher prevalence of folate deficiency(9.70 nmol/L, 31.0%) than did women(14.2 nmol/L, 12.5%, P=0.001). (2) Men in South have significantly higher plasma folate concentration and lower prevalence of folate deficiency than in North. The difference of plasma folate concentration was not evident between urban and rural area, but evident in North between in winter and spring. There were no significant differences of prevalence of folate deficiency for men between urban and rural areas in both regions. For women, the differences of plasma folate concentration in areas were significant, which were higher in South and urban, and lower in North and rural areas. (3) Plasma folate concentration increased with age in Southern men. A similar trend for others was not significant. Conclusion: Men have lower plasma folate concentration and higher prevalence of plasma folate deficiency than do women. The distribution of plasma folate concentrations in urban and rural areas seems different between men and women.

The relationship between the hepatic ischemia/reperfusion (I/R) injury and the balance of nitric oxide/endothelins (NO/ET) was studied. The changes of the ratio of NO/ET and the hepatic injury were observed in a rat hepatic I/R model pretreated with several tool drugs. In the acute phase of hepatic I/R injury, the ratio of plasma NO/ET was reduced from 1.58 +/- 0.20 to 0.29 +/- 0.05 (P < 0.01) and the hepatic damage deteriorated. NO donor L-Arg and ET receptor antagonist TAK-044 could alleviate the hepatic I/R injury to some degree, whereas NO synthase inhibitor L-NAME aggravated the damage. It was concluded that the hepatic I/R injury might be related with the disturbance of the NO/ET balance. Regulation of this balance might have an effect on the I/R injury.

Objective: To compare two methods (microbial assay and radioimmunoassay) for measuring plasma folate concentrations, and to examine the relationship between plasma folate levels, and alcohol consumption, tobacco use and body mass index, and the risk of hyperhomocysteinemia in China. Methods: We used a microtiter plate microbial assay and a radioimmunoassay to measure the folate concentration in 88 plasma samples. After comparing the results of these two methods and fitting a regression line, we examined the geographical, seasonal, and gender differences in folate concentration of plasma collected from 2 422 adults in south and north areas in China, and evaluated the association of plasma folate concentration, with alcohol consumption, cigarette smoking, and body mass index, and with the risk of hyperhomocysteinemia, using the data from the two assays. Results: The data from the two assays had a linear relationship ( r =0.879, P =0.000); the regression was Y =0.683 X +0.308 (where X and Y were nature logarithmic transformations of plasma folate by microbial assay and radioimmunoassay, respectively); however, the mean plasma folate levels by microbial assay were much higher than those obtained by radioimmunoassay. Both data sets showed similar plasma folate distributions among Chinese adults, associations with other risk factors, and the risk of hyperhomocysteinemia. We estimated that 19.9% of the Southerners and 67.1% of the Northerners had plasma folate concentrations by radioimmunoassay lower than the 6.8 nmol/L used to define plasma folate deficiency. Conclusion: There is a linear relationship between plasma folate levels determined by microbial assay and radioimmunoassay, but because of the different levels obtained in the two assays, it is difficult to use the microbial assay results to evaluate folate status at this time. The use of 10.5 nmol/L as a cut off for plasma folate deficiency by microbial assay needs further study.
