Objective To analyze the application value of evidence-based nursing(EBN) in LASEK surgery.Methods Totals of 120 cases of LASIK surgery patients from December 2013 to December 2015 were selected, and divided into observation group and control group by sortition. Patients in observation group received EBN, while patients in control group received routine nursing. Systolic blood pressure(SBP), diastolic blood pressure( DBP ) , heart rate, and SAS score before surgery, postoperative complications after 1 week, visual acuity, diopter and intraocular pressure after 4 weeks, and Haze grading are observed in two groups. Results The preoperative SBP, DBP and heart rate in observation group were lower than in the control group, SAS score in observation group was lower than the control group, differences were statistically significant ( P<0.05);complication rate 1. 67% in observation group was lower than 8. 67% in control group 1 week after surgery. The difference was statistically significant (χ2=5. 886, P<0. 05 ); 4 weeks after surgery, visual acuity in observation group was higher than that in control group, diopter was lower than in control group, and intraocular pressure was lower than in control group, The difference was statistically significant ( P<0.05);4 weeks after surgery, 1.67% patients in observation group were Haze 1 and was lower than that 11.67% in control group (P<0.05).Conclusions The application of EBN in LASEK surgery can effectively relieve patients′negative emotions, reduce the complication rate, and improve the surgical curative effect.

At present, the contents and class hours of contact lens course cannot meet the teaching and clinical requirements. Therefore, the curriculum of contact lens on practical operation was optimized, the number of practice hours was increased, and various models for practice course were applied, including problem-based learning, community practice course, and practice enhancement course, to improve students' learning interest and initiative. A variety of evaluation models were used to help teachers understand the performances of their students and make adjustments in the process of teaching and evaluation, so as to improve students' score of practical test, help them better master the practical skills and enter clinical practice without difficulties. The feedback scores of teachers in clinical practice have also been improved compared with the former ones.

Objective: To observe the effect of traditional Chinese medicine foment package in spontaneous heat position pad to prevent lower extremity deep venous thrombosis (LEDVT) during general anesthesia. Methods: From April 2018 to April 2019, 160 cases during general anesthesia were selected and divided into the control group(common hot pad for leg and knee) and the experimental group(self-control position pad for leg and knee) with 80 cases each by the random number table method. The coagulation function and deep venous thrombosis were observed and compared between the two groups. Results: There was no significant difference in coagulation function between the two groups on the 1 day before operation (P > 0.05). The level of D-dimer, prothrombin time, fibrinogen, platelet count on the 5 days after operation was (1.28 ± 0.39) g/L, (11.75 ± 0.81) s, (4.37 ± 0.71) g/L, (203.39 ± 32.12)×10⁹/L in the control group, and (0.96 ± 0.17) g/L, (11.45 ± 0.67) s, (3.93 ± 0.65) g/L, (186.10 ± 34.69)×10⁹/L in the experimental group, and there was significant difference between the two groups (t=2.553-6.728, P <0.01). The incidence of LEDVT on the 5 day after operation was 4%(3/80) in the experimental group and 18% (77/80) in the control group, and there was significant difference between the two groups (χ²=5.005, P<0.05). Conclusions The spontaneous fever knee pad with traditional Chinese medicine foment package can improve the blood coagulation function of general anesthesia patients, and the incidence of LEDVT is lower than that of the control group 5 days after operation.

ObjectiveTo evaluate the effectiveness of stone needle thermocompression and massage compared to flurbiprofen gel patch in relieving chronic musculoskeletal pain in the shoulder and back， and to explore the potential mediating mechanism through muscle elasticity. MethodsA total of 120 patients with chronic musculoskeletal pain in the shoulder and back were randomly assigned to either stone needle group or flurbiprofen group， with 60 patients in each. The stone needle group received stone needle thermocompression and massage for 30 minutes， three times per week； the flurbiprofen group received flurbiprofen gel patch twice daily. Both groups were treated for 2 weeks. Pain improvement， as the primary outcome， was assessed using the Global Pain Scale （GPS） at baseline， after 2 weeks of treatment， and again 2 weeks post-treatment. To explore potential mechanisms， a mediator analysis was conducted by measuring changes in superficial and deep muscle elasticity using musculoskeletal ultrasound at baseline and after the 2-week treatment period. ResultsThe stone needle group showed significantly greater pain relief than the flurbiprofen group 2 weeks post-treatment. After adjusting for confounders related to pain duration， the between-group mean difference was -8.8 ［95% CI （-18.2， -0.7）， P＜0.05］. Part of the therapeutic effect was mediated by changes in deep muscle elasticity， with a mediation effect size of -1.5 ［95% CI （-2.0， -0.9）， P = 0.024］， accounting for 17.9% of the total effect. ConclusionStone needle thermocompression and massage can effectively relieve chronic musculoskeletal pain in the shoulder and back， partly through a mediating effect of improved deep muscle elasticity.
