ABSTRACT
Purpose: To propose a three?step sterilization method for Goldmann tonometer prism (GTP) and to analyze the sterilization effects of each step. Methods: 120 patients (240 eyes) who underwent Goldmann applanation tonometer (GAT) IOP measurement were enrolled in this study. GTPs were used individually for each patient and wiped by swabs soaked with 75% ethyl alcohol, ofloxacin eye drops, and 75% ethyl alcohol for at least 5 s. GTPs were directly pressed onto the surface of agar plates before (W0) and after three?step sterilization (W1, W2, and W3). All the agars were sent to the laboratory in 2 h and incubated at 37°C for 48 h. Subsequently, the growth of microbial species was assessed through visual inspection of the colonies at the inoculation points on the agar surface. Results: Staphylococcus. epidermidis was the most frequently isolated bacterium and was observed in 23.33% of all prisms. Most of the bacteria were eliminated at W3 except Staphylococcus. epidermidis and Kocuria roseus in one case. The isolation rates of Staphylococcus genus and Staphylococcus. epidermidis were significantly decreased (both with P < 0.001). The number of bacteria types isolated from prisms at time point W2 and W3 had a statistically significant difference compared with W1 and W (both with P < 0.05), while W2 and W3 exhibited no significant difference. Conclusion: This three?step sterilization method for GTP proved to be effective and safe for repeated use. We recommend using ofloxacin to prevent the transmission of pathogens based on ethyl alcohol, which could also bring some economic benefits.
ABSTRACT
@#Objective To investigate the current status of outpatient pain management in patients with pulmonary disease after surgery by WeChat and to provide a basis for postoperative pain management. Methods A total of 449 patients who underwent thoracic surgery in our hospital from December 2017 to May 2018 were enrolled, including 156 males and 293 females with an average age of 22-83 (55.54±11.17) years. Brief Pain Inventory was adopted for pain assessment in 24-48 hours after discharge and 24 hours after removal of from the wound. Results Totally 98.22% of the patients reported that they suffered from pain in 24-48 h after discharge, most pain position was still at drainage port (45.21%), the overall pain score was 2.75 (2.00, 3.25) points, and 82.85% of patients adopted physical methods to relieve pain. After removal of stitches at the drainage port, 79.29% of the patients suffered from pain, the pain site was mainly at the drainage port (47.88%), and the overall pain score was 1.75 (1.25, 2.25) points, and 73.94% of patients adopted physical methods to relieve pain. The score of the overall influence degree of pain on patients was 2.29 (1.86, 2.86) points and 1.86 (1.29, 2.43) points, while pain had the greatest influence on sleep and mood. The scores were 4.00 (3.00, 5.00) points, 3.00 (2.00, 4.00) points and 2.00 (1.00, 4.00) points, 3.00 (2.00, 4.00) points, respectively. Conclusion Under the concept of enhanced recovery after surgery, the overall pain level of patients with pulmonary disease after discharge is mild pain, but the application rate of drug analgesia in patients is low. The overall effect of pain on postoperative patients with lung cancer is low, but it has a great impact on sleep and mood. Medical staff should strengthen the pain education for patients in order to improve their pain self-management ability.
ABSTRACT
The chemical constituents of fistular onion stalk obtained by supercritical CO2 extraction were separated and purified by silica gel and sephadex LH-20 gel column chromatography and the preparative TLC method and four flavonoids were obtained.On the basis of the spectral data,they were structurally identified as(+)-catechin,(-)-epicatechin,astragalin,and 3-O-β-D(2-O-β-D-glucopyranosyl)-glucopyranosides of kaempferol.
