ABSTRACT
OBJECTIVE@#To compare the clinical efficacy between visual trephine arthroplasty assisted percutaneous transforaminal endoscopic discectomy (VPTED) and traditional percutaneous transforaminal endoscopic discectomy(PTED) in the treatment of lumbar disc herniation.@*METHODS@#The clinical data of 60 patients with lumbar disc herniation admitted from June 2019 to December, 2020 was retrospectively analyzed. There were 38 males and 22 females, aged from 26 to 58 years old with an average of (43.63±8.48) years, 47 cases were on L4,5 segment and 13 cases were on L5S1 segment. Among them, 32 were treated with VPTED (group A) and 28 were treated with traditional PTED (group B). The general conditions of all the patients were recorded, including intraoperative fluoroscopy times, operation time, hospital stay and surgical complications during follow-up. The arthroplasty area ratio was observed by sagittal CT at the middle level of the intervertebral foramen. Visual analogue scale (VAS) and Japanese Orthopaedic Association (JOA) score of low back pain, Oswestry disability index (ODI) were used to evaluate the clinical efficacy between two groups.@*RESULTS@#All patients were followed up from 9 to 15 months with an average of (12.10±1.16) months. There was no statistical difference of preoperative general data between two groups. The operation time, fluoroscopy times and hospital stay were (70.47±5.87) min, (13.66±1.34) times and (6.31±0.69) d in group A, and (90.71±7.66) min, (22.82±2.48) times and (6.54±0.92) d in group B. The operation time and intraoperative fluoroscopy times in group A were lower than those in group B(P<0.05). There was no significant difference in hospital stay between two groups (P>0.05). No obvious surgical complications were found during the follow-up in both groups. The arthroplasty area ratio in group A was (29.72±2.84)% and (29.57±2.20)% in group B, respectively, with no significant difference (P>0.05). There was no significant difference in VAS, ODI and JOA score between two groups before operation and at the final follow-up(P>0.05), but the final follow-up was significantly improved(P<0.05).@*CONCLUSION@#The two surgical methods have definite clinical efficacy in the treatment of lumbar disc herniation. Visual trephine arthroplasty assisted percutaneous transforaminal endoscopic discectomy has the advantages of high efficiency and rapidity when establishing the channel, and can significantly reduce the operation time and intraoperative fluoroscopy times.

It made a brief introduction to a series of AQo (assessment of quality of life) instruments,which was consisted of the developments,features,utility tariffs and applications about AQoL-4D,AQoL-6D,AQoL-7D and AQoL-8D,so as to provide basic support for health economic evaluations,especially for health utility measurements and cost-utility analysis in China.
ABSTRACT
It systematically summarized Finland's 15D instrument's development,content and its application status in health eco-nomic evaluation field,so as to provide references for implementing economic evaluation research in China,especially for health utilitymeasurement and cost-utility analysis.
ABSTRACT
AIM: To estimate the pooled prevalence of myopia among primary school students in mainland China during 1980- 2013. Myopia had become a growing public health issue, with high prevalence rates in mainland China, particularly among children. However, we still had no population-based nationwide studies of the prevalence of myopia among primary school students in recent years. METHODS: Wanfang, Chinese National Knowledge Infrastructure and PubMed databases were searched independently until Dec. 31, 2013 to identify relevant articles. Data from the eligible articles were extracted by two reviewers. All of the data analyses were conducted using Meta-Analyst software (version 3. 13, USA). RESULTS: Thirty - seven eligible studies published between 1980 and 2013 were selected with a total of 245248 individuals. The pooled prevalence of myopia among the included individuals was 26. 5% (95% CI: 21. 8% -31. 7%). The prevalence of myopia increased with age (from 8. 4%at 6-8y to 57. 4% at 12-14y). CONCLUSION: The pooled prevalence of myopia among primary school students in mainland China was much higher than that of western countries or regions. The prevalence of myopia increased with age among primary school students. This study should be valuable for myopia prevention and treatment in mainland China.
