2.Comparison and selective preference of preparation methods of platelet-rich gel
Chinese Journal of Tissue Engineering Research 2014;(3):476-481
BACKGROUND:Platelet-rich plasma gel contains some kinds of growth factors, which play important roles in repair of local trauma and bone defects. Platelet-rich plasma gel is now more and more studied as tissue engineering scaffolds, but there are no unified preparation methods.
OBJECTIVE:To summarize the studies about the preparation methods of platelet-rich plasma gel and the growth factors in platelet-rich plasma gel in recent years, and to compare different methods in order to find which one is better.
METHODS:A online search of PubMed database from January 1980 to January 2013 and China National Knowledge Infrastructure from January 1980 to January 2013 was performed with the key words of“platelet-rich plasma, platelet-rich plasma gel, tissue engineering”in English and Chinese, respectively. The studies about detection and preparation methods of platelet-rich plasma were included and those unrelated to platelet-rich plasma were excluded. Final y, 322 articles were gained and 67 articles were included in result analysis.
RESULTS AND CONCLUSION:Al preparation methods have their advantages. We should select the suitable method according to the goal of study. With the further study of platelet-rich plasma, it wil become more and more important for bone defect repair and tissue engineering research.

Good standardized training of resident physicians is indispensable for high quality medical personnel building.This paper gives a brief introduction to the experiences of endocrinology fellowship trainings in three top hospitals in USA.On the basis of current simation in China,a new and improve the quality'is proposed,and a new approach is explored,which is a valuable reference for the endocrine resident trainings in China.
4.A General Introduction of HIV/AIDS Treatment with Traditional Chinese Medicine in China
Virologica Sinica 2007;22(6):471-475
This paper gives a general introduction of HIV/AIDS treatment with Traditional Chinese Medicine (TCM) in China during the past 20 years. Although the role of TCM in treatment of HIV/AIDS is promising, there is still a long way to go.
6.Evaluation of tramadol for patient-controlled intravenious analgesia after abdominal total hysterectomy
Journal of Xi'an Jiaotong University(Medical Sciences) 1982;0(04):-
Objective To compare the effects and side effects of tramadol and morphine used for patient-controlled analgesia (PCA) delivery system after abdominal total hysterectomy Methods A single centre, randomized double-blind study of ASAⅠ~Ⅱ 80 patients undergoing elective abdominal total hysterectomy with inhalational anesthesia was performed. The patients were divided into four groups: tramadol group (group T, n=20), morphine+droperidol group (group M+D, n=20), morphine group (group M, n=20), and tramadol +droperidol group (group T+D, n=20). The study lasted for 24 h and the following data were collected: heart rate, blood pressure, respiration, VAS, sedation score (SS), Prince Henry score (PHS) as well as side effects. The consumption of analgesics within 24 hours were also recorded. Results VAS and PHS showed no differences between the four groups. M+D group was higher than the other groups in 4, 8, and 12 h of SS. The rates of postoperative nausea and vomiting (PONV) of group T and group M were higher than those of group M+D (P
7.Evaluation on technical efficiency of high-tech medical equipment in county-level public hospitals in Guangxi based on DEA model
China Medical Equipment 2016;13(8):108-111
Objective:To evaluate the efficiency of high-tech medical equipment of county-level hospitals in Guangxi Zhuang Autonomous Region, and to provide a scientific foundation for high-tech medical equipment configuration planning for county-level hospitals.Methods: DEA model was used to evaluate the relative efficiency of 40 county-level hospitals in Guangxi.Results: 4 among 40 hospitals (10.00%) could be categorized as effective hospitals, and pure technical efficiency is not high in 30 hospitals (75.00%). The returns to scale decreased in 20 hospitals (50.00%), and 16 hospitals (40.00%) increased. The average number of the overall efficiency, pure technical efficiency and scale efficiency of the 40 hospitals were 0.684, 0.753 and 0.908 respectively. Conclusion: Departments concerned should set reasonable evaluation index to ensure that the evaluation is scientific. Hospitals should strengthen the internal management of high-tech medical equipment to improve the utilization rate of the equipment. Departments concerned are supposed to curb or enlarge the number of the high-tech medical equipment to improve the scale efficiency of the equipment.
8.Studies on the Feasibility of Celiac Axis Ligation
Chinese Journal of Bases and Clinics in General Surgery 2003;0(03):-
Objective To summarize the study on the feasibility of celiac axis ligation. Methods Literatures about celiac axis ligation were reviewed retrospectively. Results Celiac axis branches included common hepatic artery, splenic artery, left gastric artery which had many variation and collateral flow between celiac and mesenteric vessels by gastroduodenal artery and pancreaticoduodenal artery. Celiac axis could be possibly ligated without obvious complications in patients who had celiac axis injuries, celiac artery aneurysms, upper gastrointestinal haemorrhage, excision of carcinoma around the celiac axis and portal hypertension. However, gallbladder necrosis or perforation, focal infarction of the liver even higher mortality had also been reported. Conclusion Celiac axis ligation should not be performed routinely, but it is surgically possible and may be a life saving approach in certain circumstances.
9.CT Diagnosis of Mediastinal Teratoma
Journal of Practical Radiology 2001;0(06):-
Objective To discuss the CT features of mediastinal teratoma.Methods 35 patients with mediastinal teratoma confirmed by clinical and pathologic data were retrospectively analyzed.Results Most mediastinal teratomas(97.1%) were localized in the middle or upper area of anterior mediastinum.Mediastinal teratoma included cystic teratoma(60.0%) and solid teratoma(40.0%).All kinds of tissues could be found in the tumors.CT features of cystic teratoma(n=21) were the cystic mass with fluid density,most of them(n=19) had the characteristics of "obviouswalled cysts".CT features of solid teratoma(n=14) were the soft-tissue mass with mixed densities.CT features of malignant teratoma(n=5) were that the layer of fatty tissue between the tumor and the surrounding structures disappeared,and that the wall of neighbour vessels were mostly or all surrounded by the tumor.Mediastinal teratoma could cause pleural offusion(n=6) and pericardial offusion(n=12).Conclusion Mediastinal teratomas have obvious CT imaging features.CT has very important value in the diagnosis and differential diagnosis of mediastinal teratoma.
