[Purpose/Significance] To analyze the factors affecting the quality of 24-hour self-service library service under the background of normal state of COVID-19 epidemic prevention and control, and to perform comprehensive and reasonable evaluation. It is of certain guiding significance for self-service libraries to deal with possible public health emergencies in the future. [Method/Process] Through semi-structured interviews, using root theory, combining the characteristics of 24-hour self-service libraries, and from the aspects of literature resources, physical environment, system function, interaction quality and management level, we selected 21 indicators to build service quality evaluation index system, and used hierarchical analysis to determine the weight of various indicators, form a calculation formula of self-service library comprehensive score under the background of normal state of epidemic prevention and control. Finally, two 24-hour self-service libraries were selected for the empirical study. [Results/Conclusions] Under the background of normal state of COVID-19 epidemic prevention and control, and on the basis of ensuring the quality of their information resources, self-service libraries should pay attention to the environment in the libraries, improve management efficiency, and do a good job in daily maintenance.

Objective To systematically evaluate the clinical effect of regenerative technology in repairing apical bone defects. Methods A computer search was used to retrieve the regenerative technology in databases such as China Knowledge Network (CNKI), Wanfang Medical Network, VIP Information Chinese Journal Service Platform (VIP), Cochrane, Web of Science, PubMed, CBM, Ovid, Medline and other databases for repairing apical bone defects A randomized controlled study of efficacy, the retrieval time is from the establishment of the database to March 2020. Two researchers independently screened the literature, extracted the data and evaluated the quality, and used RevMan5.3 software for meta-analysis. Results A total of 27 literatures were included. Compared with the simple apical curettage group, the overall effective rate of hydroxyapatite, Bio-oss bone, hydroxyapatite combined membrane, Bio-oss combined bone membrane, and biofilm was higher and the cure rate was higher. Higher, the difference was statistically significant (P<0.05). Conclusion The regenerative technique has a better clinical effect than simple apical curettage, and it can better repair apical bone defects. [ABSTRACT FROM AUTHOR]

Objective To investigate the correlation between the range of dead bone of the patients,with spinal tuberculosis and the therapeutic effect of antituberculosis drugs. Methods Ninety-six patients with spinal tuberculosis of adjacent double vertebral bodies were enrolled in the prospective cohort study. The lesions were scanned continuously with a thickness of 0. 5 mm by 320 slice spiral CT. The largest extent of the dead bone on the axial section,the coronal section and the sagittal section were calculated respectively. The patients were treated by standard antituberculosis chemotherapy regimen. The patients whose symptoms of tuberculosis poisoning and range of dead bone and abscesses were reduced,local pain were relieved,ESR and C reactive protein decreased,were included in the effective group and were conservatively treated for 12 months. The patients with increased range of dead bone and abscesses,or achieved the indication of operation were included in the invalid group. Risk factors affecting the effectiveness of antituberculosis drugs,such as sex,age,course of disease,and range of dead bone were analyzed by univariate and multivariate logistic regression. The ROC curve was used to determine the appropriate positive reference value. Results One case of atlantoaxial tuberculosis was excluded because the dead bone of whom couldn’t be measured according to the method of measurement of spinal tuberculosis in other places. Four cases of drug-resistant tuberculosis were excluded,in which one case showed resistance by abscess puncture and culture,one by puncture biopsy and resistance gene detection,2 by postoperative pathological tissue culture. Two cases strongly required surgery because of worrying about the effectiveness of conservative treatment and then were excluded.Fifty eight patients of 89 patients enrolled in the study at last were successfully treated with antituberculosis drugs and the others undertook operation. The effective rate of conservative treatment with antituberculosis drugs was 65. 2%. The 89 patients aged 15-80 years,with an average age of 41. 2 years. There were 57 males and 32 females. The course of disease ranged from 0. 5 months to 72 months,with an average of 7. 6 months. The average range of dead bone was 5. 8% in transverse section,4. 6% in coronal section,4. 9% in sagittal section,5. 1% of composite range. When transverse sectional dead bone range exceeded 1. 9%,surgical treatment was needed probably by the result of the ROC curve. When composite dead bone range exceeded 2. 6%,surgical treatment was needed probably. Conclusions The range of dead bone of the patients with spinal tuberculosis has the correlation with the therapeutic effect of antituberculosis drugs,whereas sex,age and the course of disease do not. When transverse sectional dead bone range exceeds 1. 9%,surgical treatment is needed probably by the result of the ROC curve. When composite dead bone range exceeds 2. 6%,surgical treatment is needed probably. [ABSTRACT FROM AUTHOR]

Objective: To compare the clinical outcome between minimally invasive transforaminal approach and traditional posterior approach in the treatment of single level lumbar tuberculosis, and to evaluate the safety and reliability of minimally invasive transforaminal approach for single level lumbar tuberculosis. Methods: 73 patients with single level lumbar tuberculosis were followed up.Among them, 40 cases received traditional posterior surgery, and 43 cases received minimally invasive transforaminal surgery. The operation time, intraoperative blood loss and postoperative drainage were compared between two groups. Clinical outcomes in terms of back pain VAS score and ODI score were performed before surgery and during follow-up. Fusion rate between the two groups was comparied at the time of last follow-up. Results: After surgery, all patients significantly reduced back pain, and body temperature returned to normal within 2 week. The operation time, intraoperative blood loss and postoperative drainage in minimally invasive transforaminal surgery group were 180± 35, 350± 50, 320± 80 respectively, which were significantly less than 180± 35, 350± 50, 320±80 respectively in traditional surgery group (P<0.05). When followed up before surgery and 1 month, 3 month, 6 month, 12 month, final time after surgery, the low back pain VAS scores were 8.7± 1.2, 4.5± 1.1, 3.5± 1.1, 2.0± 1.4, 1.3± 0.5,1.2± 0.5 and the ODI scores were(77± 6)%, (31± 5)%, (23± 8)%, (14± 6)%, (8±4)%, (7± 3)% respectively in minimally invasive transforaminal surgery group. At the same times, the VAS scores were 8.5± 1.1, 2.7± 0.7, 2.1± 0.6, 1.9± 0.7, 1.1± 0.4, 1.1± 0.4, and the ODI scores were (78± 5)%, (23± 6)%, (14± 7)%, (12± 5)%,(7± 2)%, (7± 2)% respectively in traditional surgery group. The VAS and ODI scores in minimally invasive transforaminal surgery group were lower than that of traditional posterior surgery group at 1 and 3 months after operation (P<0.05), and there was no difference between two groups regarding to VAS and ODI scores at other times (P>0.05). All the patients achieved spinal fusion at the final follow-up. Conclusion: For single level lumbar tuberculosis, minimally invasive transforaminal approach can achieve the same therapeutic effect and the fusion rate with traditional posterior surgery, which was highly reliability because of lower bleeding, operation time and drainage.
