1.Methods of acquiring tumor antigens
Journal of International Oncology 2011;38(10):750-753
How to acquire new tumor antigens is a hotspot in cancer research currently.According to the nature of antigen epitope binding its ligand,we can identify and get unknown antigen epitope even its amino acid sequence through some analytical techniques and experiments,from T lymphocytes and monoclonal antibody levels.So the molecular mechanisms of tumor immunity will be more distinct.

3.Histone deacetylase 6: structure, functions and development of selective inhibitors.
Acta Pharmaceutica Sinica 2015;50(1):7-14
Histone deacetylase 6 (HDAC6) is an unique subtype of histone deacetylases with two tandem deacetylase domains and substrate specificity for non-histone proteins. It is involved in many important physiological and pathological processes and has become a promising therapeutic target in recent decades. Different kinds of potent HDAC6-selective inhibitors have been reported around the world. This paper reviews the progress in the study of structure and functions of HDAC6 as well as the development of HDAC6-selective inhibitors.
4.One case of pleomorphic adenoma originates from inferior nasal turbinate.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2014;28(20):1622-1622
Pleomorphic adenoma (PA) is the most common benign tumor of the salivary glands. Originating from the nasal cavity is very rare. This paper reports one case of pleomorphic adenoma of the inferior nasal turbinate to analyze the clinic characteristic of this disease. Although these tumors are rarely seen in everyday practice, one should consider this possibility as an uncommon aetiology when confronted with an intranasal mass.

Objective To observe the therapeutic effects of stellate ganglion block (SGB) with oxycodone and acetaminophen tablets on the treatment of migraine. Methods 100 patients with migraine were divided into two groups randomly. They received SGB with oxycodone and acetaminophen tablets (experimental group) or only SGB (control group) respectively. The parameters included pain intensity before and 1 d,3 d,1 w,1 m and 3 m after the treatment, and pain relief rate of each patient. The adverse effects were also evaluated. Results The pain intensity described as numeric rating score (NRS) decreased in the two groups at each time point. In the experimental group, the value of NRS was significantly less than that in the control group at 3d,1m and 3m after the treatment. The effec-tive rate ha the experimental group and the control group were 88% and 68%. Conclusion SGB with oxycodone and acetaminophen tablets is more effective for migraine and deserves widely used in patients.
7.Prognostic factors of 152 cases with Ⅲ/Ⅳ stage nasopharyngeal carcinoma
China Oncology 1998;0(04):-
Purpose:To compare the survival rates of hyperf ractionated radiotherapy plus concurrent chemotherapy with hyperfractionated rad iotherapy alone in the treatment of stage Ⅲ/Ⅳ nasopharyngeal carcinoma (NPC) a nd analyze the prognostic factors. Methods:Between December 1992 and December 1995, 144 NPC patien ts were randomized into hyperfractionated radiotherapy plus concurrent chemother apy (R +C) and hyperfractionated radiotherapy alone (R alone).Radiotherapy were similar in the two groups: 1.2 Gy/f, twice a day. Chemotherapy was given to R + C patients before and during the course of radiotherapy. Results:The 5-year overall survival rates of the R + C and R alone groups were 63.3% and 50.7%,repectively . The factors influencing the resu lts were N stage,chemotherapy and the peripheral blood hemoglobin concentration . Conclusions:Hyperfractionated radiotherapy plus concurrent chem otherapy can improve the survival rate, especially for the patients with N2-N3 stage.The negative prognostic factors for Ⅲ/Ⅳ NPC are N2-N3 stage, radiothera py alone and the reduction of hemoglobin during treatment.
8.Three dimensional finite element simulation of humerus fracture caused by indirect force
Orthopedic Journal of China 2006;0(08):-
[Objective]To simulate the biomechanics mechanism and environment of humeral fracture caused by indirect impact force for the purpose of biomechanics understanding and treatment of such fracture.[Method]Based on the data source, which was high-resolution anatomic slice images from approximal clavicle to distal humerus, 1 mm thickness and totally 380 layers, the geometric model of total shoulder joint was established according to the order:point, line,area, and further meshed to set up the three dimension finite element model of shoulder, fracture sites and instantaneous stress and strain of humerus were simulated and analyzed under the condition which longitudinal impact force was loaded on the humerus based on the 12 functional positions of shoulder(abduction 30?、 45?、 60?、 90?, and simultaneous neutrality, internal rotation 45?,external rotation 45?).[Result]According to the humeral shaft load-strain curve in different functional positions of shoulder, linear relation was found when load changed from 0 N to 250 N, after which non-linear come out, and even load was removed , bone was deformed eternally. With the rise in load amount, the increase in stress was detected. When abduction degree changed from 90? to 30?, the strain of humerus, both the lateral and the medial increased gradually,and increase in internal rotation 45?and external rotation 45? was more significant than that in neutrality. Meanwhile, stress difference could be seen between the lateral and the medial , and medial was larger than the lateral. Increase in stress in rotation positions was quicker and more than that in other functional positions.[Conclusion]Based on 4 abduction degrees (30?, 45?, 60?, 90?) and 3 rotation degrees(neutrality, internal rotation 45?,external rotation 45?) ,the three dimensional finite element shoulder could simulate precisely stress, strain, general trend of fracture line, three dimension images of bone failure. Three dimension finite element simulation and analysis of shoulder is a valuable mechanical method for research on biomechanics theory related to humerus fracture.

Objective To evaluate the medical efficiency of sample hospitals in Sanming city before and after Sanming health care reform.Methods One tertiary hospital,two general county hospitals and two TCM county hospitals in Sanming were sampled for the study.Two dimensions(the intensity index of medical work and work efficiency index)were selected.In addition,six indexes were identified,namely the number of discharged patients,number of outpatients and emergency diagnostics,doctor′s daily workload per capita for inpatients,bed turnover times,bed utilization rate and average days of stay.Descriptive trend analysis and comprehensive index method were applied in turn to evaluate the longitudinal changes in medical efficiency at the sample hospitals before and after the medical reform.Results The five sample hospitals in Sanming were found with less days of stay in average,and three were found with year-by-year rise of medical efficiency index,with one of them rising from 1.57 to 2.42.Conclusions Sanming′s health care reform has effectively improved internal operational efficiency at the sample hospitals,and has well addressed the relationship of medical service efficiency and scale expansion.On the other hand,the relationship between work intensity and medical efficiency needs to be further balanced,resource allocation to be further optimized,and more priority to be put in the development of TCM hospitals.
