The cure rate of the two groups showed no difference on the eighth week. Conclusions Application of Mepilex to treat patients with high risk of pressure sore has good effect.

Objective To investigate the effect of intraperitoneal injection of thalidomide on pain behaviors in a mouse model of bone cancer pain. Methods 36 male C3H/HeJ mice were divided randomly into tumor group (n= 18) and sham group (n= 18) ,six mice from each group were chosen to examine the time course of changes in behavior after tumor cells inoculated to the bone. 2 × 105 osteosarcoma NCTC 2472 cells were implanted into the intramedullary space of the right femurs of mice to induce ongoing bone cancer related pain behaviors. The sham group was inoculated by α-MEM without any cells. On the day before inoculation,the tumor mice were divided randomly into tumor + thalidomide group and tumor + vehicle group. The sham group mice were further divided randomly into sham + thalidomide group and sham + vehicle group. Pain ethology indexes such as paw withdrawal mechanical threshold (PWMT) and paw withdrawal thermal latency (PWTL) were observed on 1 d before inoculation and on 3 d ,5 d ,7 d, 10 d, 14 d after inoculation. Results ( 1 ) At day 7 after the operation, compared with sham mice ( 1. 70 ± 0. 33 ) g, PWMT of tumor mice decreased to ( 1.07 ± 0. 30) g (P ＜ 0. 05 ). At day 10, PWTL shortened to ( 12.60 ± 1.69 ) s (P ＜ 0. 05 ) compared with sham mice ( 17.70 ± 1.54 ) s. And the pain behaviors of tumor mice were aggravated along with the development of cancer pain. (2) At day 7 after the operation, compared with tumor + vehicle group ( 1. 07 ± 0.39 ) g, PWMT of tumor + thalidomide group increased to ( 1. 53 ± 0. 39 ) g (P ＜0.05). At day 10, PWTL extended to ( 16.48 ± 1.13 ) s compared with sham mice ( 12.64 ± 1. 56) s (P ＜0. 05 ). Conclusion Intraperitoneal injection of thalidomide can efficiently relieve mechanical hyperalgia and thermal hyperalgia in a mouse model of bone cancer pain.

Objective:To determine the predictive value of serum neurofilament light chain (NfL) on neurologic function in out-of-hospital cardiac arrest (OHCA) patients.Methods:The clinical data of 96 OHCA patients admitted to Cangzhou Central Hospital from January 2018 to March 2022 were retrospectively analyzed. According to the Glasgow-Pittsburgh cerebral performance category (CPC) upon hospital discharge, the patients were divided into the favorable neurologic function (grade 1-2) and poor neurologic function (grade 3-5) groups. The difference of serum NfL was compared between the two groups, and the relationship between serum NfL and neurologic function was assessed using correlation analysis and logistic regression analysis. The area under the curve (AUC), sensitivity, and specificity of serum Nfl were calculated by receiver operating characteristic (ROC) curve. Hanley & McNeil method test was used to compare the difference of AUCs between serum NfL and neuron specific enolase (NSE).Results:Twenty-six percent (25/96) patients were discharged with favorable neurologic function. Serum NfL in the favorable neurological function group was significantly lower than that in the poor neurologic function group (47.6 pg/mL vs. 261.4 pg/mL, P<0.001). Correlation analysis showed that serum NfL was positively correlated with neurologic function ( r=0.69, P<0.001). Logistic regression analysis showed that serum NfL was independently associated with neurological function ( OR=0.92, 95% CI: 0.86-0.98; P=0.010). ROC curve indicated that the AUC of serum NfL in predicting poor neurologic function was 0.95 (95% CI: 0.92-0.99), with a sensitivity of 84.5% and a specificity of 100% at the cutoff value of 80.0 pg/mL. The AUC of serum NSE in predicting poor neurologic function was 0.79 (95% CI: 0.69-0.89), with a sensitivity of 67.6% and a specificity of 80.0% at the cutoff value of 45.1 ng/mL. A pairwise comparison using Hanley & McNeil method showed that the AUC of serum NfL in predicting poor neurologic function was higher than that of NSE ( Z=3.22, P=0.001). Conclusions:Serum NfL is helpful for clinician to predict neurologic function in OHCA patients.
