Objective To find out the recent progress in research of cl inical appl ication of fascia lata allograft. Methods The domestic and international articles were reviewed to summarize the princi pal properties, processing techniques, and various uses of fascia lata allograft. Results Histologically fascia lata is composed of parallel and compact bundles of collagen fibers with few cells and immunologically it is low-antigenic. After varied tissue processing and storage techniques, fascia lata, as the scaffold only with the extracellular matrix, has been used in cl inical practice and achieved good results, such as ophthalmology, urology, and orthopaedics. Conclusion Because of these unique properites in repairing defects and reconstructing functions, fascia lata allograft, as a natural biomaterial, is promising to be used in more aspects withthe development of the biomedical techniques.
To explore the method of inducing axial vascularization in a processed bovine cancellous bone scaffold by using an arteriovenous loop, and to evaluate its effect of vascularization. Methods Custom-made processed bovine cancellous bone discs were processed into cyl inder with circular grooves. Thirty male SD rats weighing 300-350 g (3-4 months old) were randomly divided into 2 groups (n=15 per group): experimental group in which the femoral veins in the groin of rats were separated and transplanted to the contralateral femoral artery and vein stump, the processed bovine cancellousbone scaffold was inserted into the arteriovenous loop, which was placed into the annular groove. Control group, in which the blood vessels in the groin of rats were cut, no anastomosis was conducted, and the processed bovine cancellous bone scaffold was planted. At 2, 4 and 8 weeks after operation, gross observation, ink infusion histology observation and microvessel bulk density detection were conducted. Results At each postoperative time point, the samples in the experimental group were fresh red, the circulation of blood vessels were smooth bidirectionally, while the samples in the control group were dark red soft, and flexible. Ink infusion histology observation showed the processed bovine cancellous bone scaffold in the experimental group had obvious vascularization, the blood vessels tended to be mature and integrated into network, and neovascular sprouts originated from arteriovenous loop were evident, especially at 8 weeks after operation; while there was no vascularization in the control group. At 2, 4 and 8 weeks after operation, the bulk density of the microvessels in the experimental group was (3.59 ± 1.84), (16.61 ± 10.23) and (39.04 ± 13.46) μm3/μm3, respectively, and it was (2.43 ± 0.97), (6.79 ± 2.92) and (25.31 ± 10.98) μm3/μm3, respectively, in the control group. Significant differences was noted between two groups at 4 and 8 weeks after operation (P lt; 0.05), and no significant difference was evident at 2 weeks after operation (P gt; 0.05). Conclusion Inducing vascularization in a rocessed bovine cancellous bone using an arteriovenous loop is a new strategy of prevascularization and may provide valuable clues for the preparation of functional artificial bone

After 38 years of development, the procedure of selection and evaluation of the World Health Organization Essential Medicine List (WHO EML) is increasingly scientific and formal. However, peer review for the applications of WHO EML is always required in a short period. It is necessary to build up a set of methods and processes for rapid review. The most important items for the rapid review of WHO EML peer reviewers are: 1) to confirm the requirements and identify the purposes; 2) to establish the research questions and translate the questions into the ‘Participants, Interventions, Comparators, Outcomes, Study design' (PICOS) format; 3) to search and screen available evidence, for which high-level evidence is preferred, such as systematic reviews or meta-analyses, health technology assessment (HTA), clinical guidelines; 4) to extract data, where we extract primary information based on the purposes; 5) to synthesize data by qualitative methods, assess the quality of evidence, and compare the results; 6) to provide the answers to the applications, quality of evidences and strength of recommendations. Our study established a set of methods and processes for the rapid review of WHO EML peer review, and our findings were used to guide the reviewers to fulfill the 19th WHO EML peer review. The methods and processes were feasible and met the necessary requirements in terms of time and quality. Continuous improvement and evaluation in practice are warranted.
ObjectiveTo evaluate the effects of sevoflurane and propofol on preoperative implicit and explicit memories in general anaesthesia patients of elective surgery. MethodsThe surgical inpatients in Sichuan Provincial People's Hospital were enrolled from December 2013 to May 2014, and were randomly divided into three groups (S, P, M). In Group S, anesthesia was induced and maintained with sevoflurane. In Group P, anesthesia was induced and maintained with propofol. Midazolam was not utilized throughout the whole anaesthesia for the above groups. Patients in Group S and Group P were given a list of test materials to remember and listen before the anesthesia. Within 12 to 36 hours after operation, memory was assessed, based on the Buchner's model applied on the process dissociation procedure (PDP) using a phrases task. The Group M was given the same test materials, and received test with the PDP in 12 to 36 hours before surgery. Value A and value R were used to represent the implicit memory score and the explicit memory score, respectively. ResultsA total of 150 patients were included, and 50 cases were included in each group. During testing, 2 cases were excluded, 3 cases were loss to follow-up, so finally 49 cases were included in the Group S, 47 cases in the Group P and 49 cases in the Group M. The results showed that there were significant differences in the implicit memory score (A) and the explicit memory score (R) among the three groups (all P values <0.05). The explicit memory score (R) of the Group M was higher than those of the Group P and Group S (all P values <0.05), the implicit memory score (A) in the Group M was higher than those of the Group S and Group P (all P values <0.05), and the implicit memory score (A) in the Group S was higher than that of the Group P (P<0.05). ConclusionPropofol and sevoflurane can decrease the score of explicit memory after anesthesia within 12 to 36 hours, and there are no significant differences in explicit memory between the two drugs. Both propofol and sevoflurane can decrease the score of implicit memory, but the influence of sevoflurane on the implicit memory is less than propofol within 12 to 36 hours.
The concept of clinical trial transparency has been promoted for more than 40 years. The act of clinical trial registration, report guidelines development, and data sharing has has been strongly pushed forward and become a common practice. The clinical trial process being the key procedure of trial operation and quality control, determines the accuracy of the results. However, the process report of clinical trials is insufficient. In this article, we summarize the importance of clinical trial process report and provide corresponding suggestions. We propose that medical journals, reporting guidelines developers and clinical trial registration platforms should work together to strengthen the process report of clinical trials and promote full transparency of clinical trials.
ObjectiveGiven the relatively limited resources available for tumor radiotherapy, the reengineering theory to the tumor radiotherapy process of a tertiary hospital is applied to improve the efficiency of medical service, shorten patient waiting time and improve patient satisfaction. MethodsThe tumor radiotherapy process of a tertiary hospital was studied from January 2017 to September 2018. The indicators such as efficiency and satisfaction were analyzed before reconstruction (from January to December 2017) and after reconstruction (from January to September 2018). ResultsAfter radiotherapy process reengineering, on the one hand, the medical efficiency was improved: the number of new patients for radiotherapy per month rose by 16.58% (P<0.05), and the number of daily radiotherapy increased by 5.80% (P<0.05). On the other hand, the patient treatment process became more concise: the preparation time was shortened from 2-3 days to 1 day, while the waiting time for radiotherapy was shortened by nearly 10 days, and the overall satisfaction of patients increased from 64.17% to 83.55%. ConclusionIt can improve the operation efficiency of tumor radiotherapy and improve patient satisfaction under the condition of relatively fixed resources through the reconstruction of the information-based tumor radiotherapy process.
