Objective To investigate the application of vascularized free fibula flaps in reconstruction of mandibular defect,and to evaluate the survival rate and repair effect of the method.Methods 16 patients with mandibular tumor,having a desire to reconstruct mandible,and their systemic state could tolerate the long time operation, were selected to reconstruct mandibular defect by vascularized fibula flaps,of which 12 were male,4 female,aged 24-66 years old,average 45.2 years old.The resection of primary tumor and free fibula flaps were simultaneously conducted,then the fibular flaps were shaped according to the defect location and size of the mandible,and were fixed with reconstructive titanium plate for repair and reconstruction of mandible. The survival of flaps was determined by skin color, texture, and skin temperature of the flaps. The reconstruction effects were evaluated through the patients’surface like photos and X-ray picture of mandible before and after operation.Results All of flaps were survived and no serious complications were found. The complications of the supplied sites were skin tension and wound dehiscence, which were healed by dressing. The mandibular reconstruction effects were good through 2 or more persons’double blind evaluation.Conclusion Free fibula flaps have high survival rate and good results in mandibular reconstruction,and they can meet the needs of various types of mandibular defect repair.

Objective:To explore the medication law and core Traditional Chinese Medicine (TCM) compounds in the treatment of blood stasis vascular dementia (VD) based on data mining.Methods:The literature about TCM treatment for blood stasis VD was retrieved from the databases of CNKI, Wanfang, VIP, and CBM from January 2000 to November 2021. Microsoft Office Excel 2019, SPSS Modeler 18.0, SPSS Statistics 25.0, R X64 4.1.2, and Origin 2021 were used to perform medication frequency analysis, frequency analysis of four properties and five tastes of TCM, association rules, clustering analysis, factor analysis and data visualization.Results:A total of 196 articles were included, with 196 TCM prescriptions, involving 200 kinds of Chinese materia medica. High-frequency drugs were for Acori Tatarinowii Rhizoma, Chuanxiong Rhizoma, Salviae Miltiorrhizae Radix et Rhizoma, Polygalae Radix, Carthami Flos. The medicinal properties were mainly warm, mild and cold, the tastes were mainly sweet, bitter and pungent, and the meridians were mainly liver meridian, spleen meridian and heart meridian. A total of 19 association rules were obtained from the analysis of association rules for 2 kinds of Chinese materia medica, and the rules of the representative were Acori Tatarinowii Rhizoma- Polygalae Radix, Chuanxiong Rhizoma- Carthami Flos, Acori Tatarinowii Rhizoma- Curcumae Radix. A total of 4 categories were extracted through clustering analysis. Factor analysis extracted a total of 8 common factors. Conclusion:The core pathogenesis of blood stasis VD is blood stasis blocking brain collaterals, and there were also pathological factors such as qi deficiency, yin deficiency, phlegm turbidity and so on. The basic treatment is promoting blood circulation and removing stasis, and different methods of promoting blood circulation and drugs are selected. The methods of strengthening spleen and reducing phlegm, nourishing yin and blood, inducing resuscitation, tonifying the kidney and spleen, regulating qi, promoting collaterals and so on can also be used based on syndromes and symptoms of the patients.

Objective To find out if there is any difference in intercondylar fossa width and notch width index (NWI) between tibial intercondylar eminence avulsion fracture and anterior cruciate ligament (ACL) injury.Methods A retrospective study was conducted of the patients who had sought medical attention at Department of Sports Medicine and Adult Reconstructive Surgery,Drum Tower Hospital from June 2014 to May 2018.There were 10 patients with tibial intercondylar eminence avulsion fracture (4 males and 6 females with an average age of 32.7 ± 9.2 years),13 patients with ACL injury (8 males and 5 females with an average age of 31.8 ± 10.9 years) and 22 patients with simple meniscus injury as controls (13 males and 9 females with an average age of 30.9 ± 10.6 years).They all had MRI examination of the knee before surgery.The width of intercondylar fossa and the width and height of bilateral femoral condyles were measured on high resolution images of MRI axial view.NWI was calculated.The 3 groups were compared in intercondylar fossa width and NWI.Results The 3 groups of patients were comparable because there were no significant differences in gender,age,height,weight or BMI between them (P ＞ 0.05).The intercondylar fossa width in the ACL injury group (17.4 ± 3.5 mm) was significantly smaller than that in the avulsion fracture group (20.8 ± 1.1 mm) or in the control group (20.2 ±2.6 mm) (P ＜ 0.05),but no significant difference was detected between the avulsion fracture group and the control group (P ＞ 0.05).NWI in the avulsion fracture group (0.301 ±0.011) was similar to that in the control group (0.280 ±0.039) (P ＞ 0.05) but significantly higher than that in the ACL injury group (0.25 ± 0.05) (P ＜ 0.05).NWI in the ACL injury group was significantly lower than that in the control group (P ＜ 0.05).Conclusions Intercondylar notch stenosis may be a risk factor for ACL injury but may not be associated with tibial intercondylar eminence avulsion fracture.The difference in pathogenesis between tibial intercondylar eminence avulsion fracture and ACL injury may be associated with their difference in NWI.

Healthy lifestyles and good living habits are effective strategies and important approaches to prevent chronic non-communicable diseases. With the development of evidence-based medicine, the evidence translation system has made some achievements in clinical practice. There is, however, no comprehensive, professional and efficient system for translating lifestyle evidence globally. Therefore, the Health Lifestyle Evidence (HLSE) Group of Lanzhou University constructed the HLSE Evidence Translation System (https://hlse.cn/), with the aim of synthesizing, evaluating, translating, and applying lifestyle-related evidence resources. This paper aims to introduce the functional module design of the evidence translation system, the system development process and testing, introduce the interface design and function demonstration, and explain the significance of constructing the HLSE.
