1.Effect of cyclooxygenase-2 inhibitor in anti-leukemia
Journal of International Oncology 2012;39(6):462-464
Cyclooxygenase-2 (COX-2) plays an important role in the development of leukemia.COX-2 inhibitor plays a certain anti-leukemia role in the process.Many studies show that COX-2 inhibitor plays antileukemia role by inhibiting the proliferation of leukemia cell,promoting apoptosis,affecting cell cycle,inhibiting cell metastasis and reversing cell drug resistance and so on.Therefore,the researches about the anti-leukemia mechanisms of COX-2 inhibitor will provide a new target in clinical prevention and treatment of leukemia.
2.Investigate progress on risk factors and risk assessment of osteoporotic fractures.
China Journal of Orthopaedics and Traumatology 2014;27(3):261-265
Osteoporotic fracture is the most destructive ending of osteoporosis, many interacting risk factors play a role in its occurrence. With age, the bodies function decline gradually. Symptoms like soreness of the waist, back pain, cramp of the lower limb and weakness appears. These are related to TCM syndrome factors like kidney deficiency, liver deficiency, spleen deficiency and blood stagnation. Symptoms can act as a warning of the occurrence of osteoporotic fracture in the early stages. The risk assessment tool of osteoporotic fracture is mostly developed on the basis of modern risk factors and thus lacks syndrome differentiation, that may limit its utilization. If the relevant content of syndrome differentiation is integrated into the forecasting tool and a risk assessment tool of osteoporotic fracture which complies with the demographics of China is built up, population risk assessment for high of risk could be established and scientific evidence for the adoption of effective interventions could be applied.

Objective To explore the mechanism of aluminum-induced damage of learning and memory by studying the change of calcium-calmodulin-dependent protein kinase Ⅱ(CaMKⅡ) in the hippocampus of lactational rats. Methods Three groups of clean pregnant Wistar rats (120-200 g) were randomly divided into 3 groups. On the first day of parturition, the dams of two groups were given 0.3% and 0.6% AlCl3 through drinking water and terminated on the weaning day (21 days). Western blot was used to determine the content and activity of ?-CaMKⅡ. Results The aluminum levels in the blood and brain of aluminum-treated rats were obviously higher than that in the control (P

In the past two decades,with the development of electron optics,computer and imaging,hip arthroscopy surgery has become the best effective method in the diagnosis and treatment of the hip discord,as a method integrates less invasive and invisible characteristics.The indication of hip arthroscopy gradually expands and has become the gold standard in the diagnosis and therapy of hip discord.Recent research shows hip arthroscopy can provide early diagnosis and treatment hip unexplained pain,such as femoroacetabular impingement(FAI),labral tears,chondral lesions,furthmore hip arthroscopy shows good prospects in the treatment avascular necrosis of femoral head,synovial abnormalities,post hip arthroplasty discomfort.

Objective To describe a new surgical approach to treatment of scapular neck and body fractures and evaluate the clinical outcomes. Methods From December 2002 to October 2004, 13 cases of the scapular neck and body fractures including 9 males and 4 females with age range of 22-48 years (mean 31 years) were admitted into our hospital. There were seven cases with neck fractures, two with associated clavicle fractures, six with mere body fractures, seven with associated subluxation of humeral head and three with associated rib fractures. Internal fixation and open reduction reconstruction using titanium plate and screws were for treatment of scapular neck and body fractures in all 13 cases by making straight incision along lateral border of the scapula. Results The operation lasted for 40-80 minutes, with intraoperative blood loss for 30-80 ml. The follow up for 4-24 months showed average fracture healing time for 6-8 weeks and satisfactory results in 10 cases. Conclusion The surgical approach with straight incision along the lateral border of the scapula can attain perfect reduction and internal fixation of scapular neck and body fractures as well as satisfactory functional recovery with minor (trauma.)

The evaluation of glomerular filtration rate is important in the diagnosis,treatment, and prognosis for patients. Although there are different equations widely used and convenient,the accuracy of them on the specific populations, including diabetic patients and the elderlys, still needs further discussion. We recommend using the Chronic Kidney Disease Epidemiology Collaboration ( CKD-EPI) from creatinine and cystatin C in the elderlys. For diabetic patients, however, this equation should be recommended with cautions.

Using gene fusion technology, polypeptide fusion tags can be engineered into target proteins at the genetic level.The resultant recombinant proteins may possess the biochemical properties of the imported fusion tags.Therefore, it is possible to take advantage of fusion tags to improve and evaluate protein expression, to detect and track protein targets, and to purify and characterize proteins.However, it is necessary to eliminate any influence of the fusion tag in structural characterization experiments or in isolating pharmaceutical proteins.Scientists must therefore remove fusion tags prior to structural and functional analyses when fusion tags are suspected of interfering with the biological activity of a protein or influencing its behavior.The fusion tag can be removed by several methods including harsh chemical treatment, mild enzymatic cleavage by endoprotease or exoprotease, and intein-mediated self-cleavage.Here the literature is reviewed in relation to principles, applications, and approaches of each method.

Objective To evaluate the outcomes of meniscal injures treated by Ho∶YAG laser using arthroscopy.MethodsA total of 31 patients with meniscal injury were treated with holmium∶YAG laser by arthroscopy from January 2006 to March 2008 in our hospital.Among the cases,11 had flap tear,8 had horizontal tear,6 showed bucket-handle tear,and 6 were found with longitudinal tear.The pre-and post-operative Lysholm score,and compilations in the patients were recorded.Results The operation was completed successfully in all the cases with a mean operation time of 44 min(rang,22-55 min).No injuries to the vessels and nerves occurred in the surgery.The patients got out of bed in 1 to 4 days after the surgery(mean,2.1 days).All the surgical wounds achieved primary healing.Follow-up was carried out in the patients for 9 to 28 months(mean,14.5 months).The patients showed significantly lower Lysholm score at 6 months during the follow-up than that determined before the operation(92?6 vs 57?13,t=13.61,P=0.00).Among the cases,21 showed excellent outcomes,7 were good,and 3 were improved.The rate of excellent and good results was 90.3%(28/31).Conclusion Ho∶YAG laser is a safe,simple,and effective tool in cutting menisci under a arthroscope.
