Chinese Journal of Primary Medicine and Pharmacy 2012;19(10):1472-1473
ObjectiveTo compare the clinical efficacy and side effects of liver damage of the methylprednisolone (methylprednisolone tablets ) and prednisone treating nephrotic syndrome compicated with hepatitis B.Methods66 patients with nephrotic syndrome complicated with hepatitis B were randomly divided into control group and observation group,and each group had 33 cases.The control group was given prednisone in the morning,while the observation group was received methylprednisolone.The clinical efficacy and side effects of liver damage were compared between the two groups.ResultsAfter the treatment,the biochemical index significantly improved compared with the pre-treatment( all P < 0.05 ) ;The total effective rate of observation group was 93.94% higher than 84.85% of the control group( x2 =1.44,P > 0.05 ).However,there was no significant difference between the two groups( P >0.05) ;The observation group was significantly higher than the control group in negative rate of HBV-DNA (x2 =4.69,P < 0.05 ) ;The side effects of liver damage in the observation group were lower than the control group (t =5.62,5.13,P < 0.05 ).ConclusionMethylprednisolone and prednisone for treating patients with nephrotic syndrome compicated with hepatitis B had good clinical efficacy,and methylprednisolone was more effective than prednisone,especially it had less side effects of liver damage than prednisone.

5.Progress in the relationship between environmental estrogen bisphenol A and obesity
International Journal of Pediatrics 2011;38(3):283-286
Bispheno|A(BPA)is an endocrine disruptor with estrgenic properties,which is a widely used industrial platicizer.When exposure to BPA for long-term,it would impact on multiple systems and organs including reproductive.developmental,neurological,endocrine function and so on,particularly in obesity.ExpoSUre to BPA during pregnancy and postnate,it can increase the sensitivity to obesity in offsprings.BPA may be contributed to obesity by enhancing triglyceride accumulation and accelerating adipocytes differentiation,affecting endocrine function of adipocytes and blood glucose and insulin metabolism.However,the dosage effect of BPA is not a simple linear rehionship.The impact of environment-related dosage on the human is worthy ot research in future.
6.Simultaneous Determination of Imperatorin, Isoimperatorin and Magnolin in Quchuan Capsules by HPLC
China Pharmacist 2015;18(10):1832-1834
Objective:To develop a method to simultaneously determine the content of imperatorin, isoimperatorin and magnolin in Quchuan capsules by HPLC. Methods:A Shiseido CAPCELL PAK C18 column(150 mm × 4. 6 mm,5 μm) was used. The mobile phase consisted of acetonitrile(A)-water(B) with gradient elution at a flow rate of 1. 0 ml·min-1 and the column temperature was at 30℃. The detection wavelength was set at 278 nm from 0 to 25 min and 248 nm from 25 to 70 min. The injection volume was 10 μl. Results:The linear range of imperatorin,isoimperatorin and magnolin was 6. 126-55. 134 μg·ml-1(r=0. 999 7), 9. 862-88. 758 μg ·ml-1(r =0.999 8) and 4.830-43.470 μg·ml-1(r =0.999 8), respectively.

9.Current research in animal models of dry age-related macular degeneration
Chinese Journal of Experimental Ophthalmology 2015;33(1):76-79
Age-related macular degeneration (AMD) is the leading cause of the irreversible vision loss in population over 55 years of age.With the increasingly serious problem of aging,the prevalence of AMD is rising year by year.However,as the pathogenesis of dry AMD is largely unknown,the effective therapy still is lack.Given that there was a lack of proper animal models,it brought about obstacles to researches about molecular mechanism underlying dry AMD.Nowadays,lots of murine models of dry AMD have been established and developed,which provide suitable tools for relevant researches.But,different dry AM D models show varied pathogenesis features,and a reasonable choice of models is very important for different studies.The characteristics of different dry models were reviewed in this article.
10.Diagnosis and treatment of bone disease of multiple myeloma
Journal of Leukemia & Lymphoma 2010;19(7):443-446
Up to 90 % of multiple myeloma patients can develop to osteolytic lesions. Although the conventional X radiography can only demonstrate the lytic bone disease when 30 % of the trabecular bone loss, it still remains the gold standard of the staging procedure of newly diagnosed myeloma patients. CT scans are more sensitive than X radiography for detecting small lytic lesions. MRI or CT is the choice of diagnosis to assess suspected cord compression. Technicium-99m bone scan in patients with myeloma usually underestimate the extent of bone damage. Treatments of myeloma bone disease include bisphosphonate therapy, novel targeted agents, surgical intervention and radiation therapy.
