1.Natural modulators of liver X receptors.
Journal of Integrative Medicine 2014;12(2):76-85
Nuclear receptor transcription factors are ligand-activated proteins that control various biological events from cell growth and development to lipid metabolism, and energy and glucose homeostasis. Nuclear receptors are important drug targets for metabolic diseases. Liver X receptors (LXRs) are nuclear receptor transcription factors that play essential roles in regulation of cholesterol, triglyceride, fatty acid, and glucose homeostasis. LXR-deficient mice have shown the association of LXR-signaling pathway dysfunction with several human pathologies including atherosclerosis, hyperlipidemia, Alzheimer's disease and cancer. Thus, LXRs are promising pharmacological targets for these diseases. Synthetic LXR agonists may lower cholesterol, but increase triglyceride and induce fatty liver. The naturally occurring LXR ligands, with moderate activity, may serve as nutraceuticals for prevention or treatment of the disorders, while minimizing potential side effects. In this review, recent advances in natural LXR modulators are summarized including agonist, antagonist and the modulator of LXR pathway.

China Oncology 2000;0(06):-
Purpose:To investigate clinical effects and side reactions of advanced NSCLC by combined chemotherapy base on gemcitabine. Methods:36 cases of advanced NSCLC were divided into two groups: Group 1, 20 cases were treated by gemcitabine 1.6 g at d1,d8,d15 and 80mg/m 2 DDP at d1; Group 2,16 cases were treaded by gemcitabine 1.6 g and paclitaxel 60 mg at d1,d8,d15.Both groups were repeated every 4 weeks and clinical effects were evaluated after 3 cycles.Results:CR 1 case, PR 17 cases, SD 16 cases, PD 2 cases and CR+PR 18 cases (response rate 50 0%) in 36 cases observed. In 20 cases primary treatments:CR+PR 11cases (response rate 55 0%);In 16 cases re-treatments: CR+ PR 7 cases (response rate 43.75%); In 15 cases of advanced NSCLC re-treated by gemcitabine combined with paclitaxel: CR+PR 7 cases (response rate 46.7%). Side reaction: most cases showed bone marrow suppression and symptoms of gastrointestinal side-effects, which included 12 cases of Ⅲ-Ⅳ grades leukocytopenia (33.3%),7 cases of Ⅱ-Ⅲ grades soterocytopenia (19.4%),8 cases of Ⅲ-Ⅳ grades symptoms of gastrointestinal side-effects (22.2%),2 cases of Ⅱ grades abnormal liver function.Conclusions:Better clinical effects have been achieved in the therapy of advanced NSCLC by combined methods based on gemcitabine and side-reactions are tolerable;Nice effects were obtained in the re-treatment of NSCLC by gemcitabine combined with paclitaxel.It is valuable to investigate its Clinical effects more deeply.
4.Diagnosis and treatment of patellar chondroblastoma.
China Journal of Orthopaedics and Traumatology 2013;26(12):1059-1062
Chondroblastoma of the patella, rare occurred in patellar,is a kind of an uncommon benign bone tumor. Compared with giant cell tumor, the morbidity of chondroblastoma is lower. Meanwhile, its clinical manifestations are various, and images are very complicated. Therefore, the understanding of this kind of tumors may be limited even to the orthopedist. The differences of patellar chondroblastoma between other tumor in X-ray, CT and MRI is a spot in recent years. Sometimes patellar chondroblastoma coexists with aneurysmal bone cyst, which is a challenge to obtain an accurate pathological and radiological diagnosis. For the treatment, curettage and bone grafting is one the most popular method, but whether to perform a biopsy before surgery still remain controversy. Some new technique still has an unknown prospect for the treatment such as radiofrequency ablation.

9.The role of exercise in child asthma's combat and management
International Journal of Pediatrics 2010;37(1):106-108
For a long time, people have different ideas about whether asthmatic children can participating in sports as others and how to exercise they need. As restricted by the possibility that exercise may induce asthma, the level of asthmatic children' s exercise is lower than their classmates. Research in recent years in abroad have showed that exercise is not only helpful to children's growth and development psycho`gicat health,but also helpful to asthmatic children's sympton control, reducing asthma exacerbation, reducing medication use and impoving their quality of life, and asthmatic children can exercise safely as long as been managed appropriatly. Scholars have paied more and more attention to the importance of exercise in children asthma' s management, and exercise prescription had been recommended as an important part of children asthma' s management in abroad.
