1.Advances on biomechanics and kinematics of sprain of ankle joint.
China Journal of Orthopaedics and Traumatology 2015;28(4):374-377
Ankle sprains are orthopedic clinical common disease, accounting for joint ligament sprain of the first place. If treatment is not timely or appropriate, the joint pain and instability maybe develop, and even bone arthritis maybe develop. The mechanism of injury of ankle joint, anatomical basis has been fully study at present, and the diagnostic problem is very clear. Along with the development of science and technology, biological modeling and three-dimensional finite element, three-dimensional motion capture system,digital technology study, electromyographic signal study were used for the basic research of sprain of ankle. Biomechanical and kinematic study of ankle sprain has received adequate attention, combined with the mechanism research of ankle sprain,and to explore the the biomechanics and kinematics research progress of the sprain of ankle joint.

2.Research progress of HIF-1 in cancers
Practical Oncology Journal 2014;(6):565-568
Transcription factorhypoxia inducible factor -1(HIF-1)plays a key role in cell adaption to hypoxia(from 21%O2 to 1%O2).Researches have shown that HIF -1 is closely related to occurrence and de-velopment in many malignant cancers .In this paper,we review the effect of HIF -1 in tumor growth,metastasis, apoptosis and angiogenesis .
3.Content Determination of Hesperidin in Shuhouyin by HPLC
Chinese Journal of Information on Traditional Chinese Medicine 2006;0(11):-
Objective To establish a HPLC method for the content determination of hesperidin in Shuhouyin. Methods Chromatographic assay was performed on CenturySIL C18-AQ (250 mm?4.6 mm, 5 ?m) column at room temperature. The mobile phase was acetonitrile-0.2% phosphoric acid solution (21∶79). The flow rate was 0.8 mL/min. The detection wavelength was at 284 nm. The sample size was 20 ?L. Results Good linear relationship of hesperidin achieved in the range of 1.004~10.04 ?g. The average recovery rate was 98.59% with RSD=0.72%. Conclusion The method is simple, accurate and stable with good reproducibility. This method can be used for determination of hesperidin in Shuhouyin.
4.Individualized surgical treatment for chronic pancreatitis
Chinese Journal of Digestive Surgery 2014;13(4):241-243
Because of the complex pathogenesis and progressive development,it is difficult to define the optimal surgical time and procedure for chronic pancreatitis.The individualized treatment of chronic pancreatitis should resect the inflammatory mass of the head of the pancreas and preserve the pancreatic parenchyma to postpone the injury of pancreatic function and improve life quality as well as decrease the risk for carcinogenesis of pancreatic cancer.Conservative and endoscopic treatment can be considered in the early stage,while surgical intervention should be applied for chronic pancreatitis with stenosis or obstruction of pancreatic duct and calcification of the pancreatic parenchyma.Frey procedure can be performed on patients only with stone in or dilation of pancreatic duct ; patients with obvious inflammatory mass or calcification of the head of the pancreas should receive Beger procedure to decrease the morbidity of pancreatic cancer.
5.Lactate and tumor
Journal of International Oncology 2012;39(2):111-113
Lactate is considered a dead-end product of glycolysis.Its generation and accumulation promotes tumor growth and metastasis,and it is related to the poor prognosis of tumor.But recent studies have found,tumor cells can also uptake and utilize lactate.With the recent advances in tumor metabolism and gene therapy,lactate is a potential therapeutic target in tumors.
6.Analysis of the anus and anal canal etiology of postoperative nosocomial infection and immune function changes
International Journal of Laboratory Medicine 2015;(3):341-342
Objective To investigate the etiology of the nosocomial infection and immune function changes anus and anal after operation.Methods 130 patients who needed anus and anal canal surgery were recruited in the study.The clinical data were recor-ded and postoperative nosocomial infection data were observed,including infection type,distribution,pathogenic analysis and im-mune function.Results A total of 67 cases of nosocomial infection occured,the infection rate was 51.5% (67/130),the main types of infection were perineal wound infection,abdominal infections and pelvic infections,urinary tract and vaginal infections were rare. 93 isolates were collected,of which gram-negative bacilli accounted for 67.7% (63/93 ),including bacteroides fragilis (21.5%), Escherichia coli (18.3%),Pseudomonas aeruginosa (10.8%);Gram-positive bacteria accounted for 23.7% (30/93 ),including Staphylococcus aureus(17.2%),Staphylococcus epidermidis(6.5%);5 fungi were isolated accounting for 5.4%,other strains ac-counted for 3.2%.All the immune parameters detected in patients with postoperative nosocomial infection were statistically differ-ent from those before infection(P <0.05)except for IgM(P >0.05).Conclusion The incidence of nosocomial infection was rela-tively high in patients who had anus and anal canal surgery,which could serious affect the patients'outcomes,preventive and control measures should be taken in clinical practice.
7.Method of auxiliary retraction in single incision laparoscopic surgery
International Journal of Surgery 2015;42(5):337-340
Single incision laparoscopic surgery (SILS) has many advantages than standard multiport laparoscopic cholecystectomy (MLC),such as small trauma,less postoperative pain,shorter hospital stay,good cosmetic effect,and so on.Especially the satisfying cosmetic result of no abdominal scar is more important.But the SILS is also faced with many difficulties.The operation time of SILS were significantly longer in duration than MLC.The safety and the technical feasibility were lower for the SILS whose operation complications are more than the MLC.The main reason is that the operation field don't exposureis sufficient and the formation of surgical operation triangle is not easy.In order to overcome these difficulties,scholars have used the auxiliary methods of exposing the operative field in various operation,including the penetration of abdomen wall retraction and intraperitonealretractionand abdomen wall retraction.This paper with review the advantages and disadvantages of the above methods aiming to affer more values for clinical doctors in opperating SILS who get more knonledge abont it.
8.Clinical observation of continuous jejunal interposition after total gastrectomy:a report of 60 cases
Chinese Journal of Postgraduates of Medicine 2014;37(z1):61-63
Objective To explore the application value of gastrointestinal reconstruction by continuous jejunum interposition after total gastrectomy.Methods A retrospective analysis in March 2006 to March 2012 was performed in 60 patients with gastric underwent continuous jejunal interposition after total gastrectomy.Results There were no operation death and anastomotic fistula.Follow-up for 12-24 months,some patients had mild reflux esophagitis,generation of gastric capacity of more than 300 ml,emptying time of 30-100 min.The quality of life was improved after operation.Conclusions Continuous jejunal interposition pouch is safe and reliable,with satisfactory effect of digestive tract reconstruction.
9.The new market -oriented training mode of nutrition majors
Chinese Journal of Medical Education Research 2003;0(04):-
In order to nurture the undergraduate majors of nutrition to fit society’s need,it is necessary to establish a new market-oriented talent training mode adaptable to both the market and society. This mode can also provide reference for the talent training of other emerging professions. Exploring the argument basis,theoretical design,practical development and research plan of this mode.
