1.Progression of lobaplatin for cancer
Journal of International Oncology 2012;(12):907-909
Lobaplatin is the third generation platinum drug.Many studies on pharmacodynamics have confirmed that lobaplatin can block the cell cycle and induce cell apoptosis,and thus inhibits tumor cell proliferation effectively.Lobaplatin is not cross-resistant to cisplatin.Besides,it has good curative effect to various kinds of cancer patients with mild adverse reactions,and the patients are well tolerable to it.

International Journal of Laboratory Medicine 2016;37(18):2534-2536
Objective To evaluate the effect of splenectomy on hematological and immune system for children with major thalas‐semia .Methods This retrospective study was performed on 68 children with major thalassemia .The indexes of blood and immune system included white blood cell ,red blood cell ,hemoglobin ,platelet ,immunoglobulin IgG ,IgM and IgA and serum complement C3 , C4 ,which were recorded at pre‐splenectomy ,3 months and 3 -12 months post‐splenectomy .Results The mean age of children in this study was 8 .6 ± 3 .1 years .There were 28 children with α‐thalassemia ,35 with β‐thalassemia and 5 with αβ‐thalassemia .The white blood cell ,red blood cell and platelet count increased significantly both at 3 and 3-12 months post‐splenectomy as compared with pre‐splenectomy .The red blood cell and hemoglobin in children with β‐thalassemia or αβ‐thalassemia were significantly lower than children withα‐thalassemia both at pre and post‐splenectomy .However ,the platelet count were similar .The immunoglobulin IgA and IgM were significantly lower at post‐splenectomy than pre‐splenectomy .However ,the IgG ,C3 and C4 did not decrease sig‐nificantly .Conclusion Splenectomy could increase the hemoglobin level and improve the anemia in children with major thalassemia . However ,it might be harmful to the immune system .

Objective To investigate the distribution characteristics of motor endplates in musculuslevatorani of dif-ferent gestational ages. Methods 20~24 weeks female fetuses were categorized as Group A, and 24~28 weeks female fetuses as group B. Karnovsky-Roots iron cyanide copper staining ( hematoxylin) was used to study the aver-age weight, the morphology, distribution and changes in number of motor end plate. Results The motor endplates morphology and distribution of consistent oval of 20 ~28 weeks female fetuses showed a curve distribution in the musculuslevatorani fibers foreign 1/3 . The weight and numbers of motor endplates in Group A were less than those of group B. Conclusion 20 ~28 weeks female fetuses' musculuslevatorani are visible on the motor end plates, and no significant difference is found in morphology and distribution of the curve along the muscle fibers. The num-ber of motor endplates increases with the increase of anal muscle weight mentioned.

Methods:An advanced biotechnology-immunoaffinity column was used for the extraction of aflatoxin Bl from the samples, and an HPLC method with post-column derivation was applied to detect aflatoxin Bl in edible vegetable oil, and the results were com-pared with those of the national standard thin layer fluorescence method. Results:The linear range of aflatoxin Bl was 10. 2-51. 0 ng · ml-1(r=0. 9996), the average recovery was 87. 3%(RSD=0. 96%, n=6), and the detection limit was 1 μg · kg-1. Conclu-sion:The method is simple, rapid and sensitive, which can be used as a promoted conventional method for the detection of a large number of samples.

Objective To analyze the articles of Journal of Intentational Oncology published from 2000 to 2009, and offer reference for the edition and publication of the journal. Methods Bibliometric analysis was used to analyze articles published in Journal of International Oncology from 2000 to 2009, including the quantity analysis, ration of fund-aided articles and authors analysis. Results 2 551 pieces of articles were published,including 182 pieces of original articals, 2 198 pieces reviews and 171 pieces of abstracts, and the density was 0. 3 piece per page. Fund-aided articles were 536 pieces and the ration of fund-aided articles was 0. 21. Fundaided articles and the ration were rising in these ten years.

BACKGROUND: It is difficult to in vitro isolate and culture the ovarian surface epithelium with high purity, strong vitality and stable biological characteristics. Tissue adherence and enzymatic digestion are commonly used for primary culture, but there are certain problems in cel col ection, cel viability and cel purity. OBJECTIVE: To establish a method for primary isolating, culturing and identifying human ovarian epithelium. METHODS: The ovarian surface epithelium was obtained with cel brush innovatively, and then the cells were isolated and purified with erythrocyte spal ation and differential adherence. The epidermal growth factor was added into the serum-free Dulbecco’s modified Eagle’s medium-F12 medium for cel culture. The cel morphology was observed under inverted microscope, and hematoxylin-eosin staining and immunocytochemical staining were used to identify the cells, then the growth curve was draw. RESULTS AND CONCLUSION: The ovarian surface epithelium became adherent after cultured for 24 hours, and reached fusion basical y after cultured for 6-12 days. The cells were polygonal or flat with strong transparency and refraction. The morphological characteristics of the cells were in line with those of the normal epithelial cells, and almost al the isolated cells could express the epithelial cells surface marker CK19. The cells could be passaged for 6-8 generations with wel growth and the cel growth curve was in “S” shape. The purity of the cells was more than 95%. The results suggest that cel brush method is simple to operate and can obtain a large amount of ovarian surface epithelium rapidly. The purity of the isolated cells can reach to 95% after treated with erythrocyte spal ation and differential adherence method and the cells are in stable growth.

To clarify the meaning, role and significance of the new idea of the modern basic theory of traditional chinese medicine, We clarified its origin and evolution starting from the basic concept of idea in this paper, re-vealed the basic connotation and relationship of ideas, scientific ideas, Chinese medicine ideas, and the new ideas of the modern basic theory of traditional Chinese medicine, and tried to give proper definitions; summarized three roles of scientific ideas. According to this basis, we demonstrated the new idea is the scientific ideas with core spirit run-ning through rational questioning, scientific testing, research and conclusion being accepted three-point line cen-tral interlocking; and have three roles changing the theory of traditional chinese medicine, guiding the innovative research on chinese medicine and elevating the scholars' thoughts. We proposed yin and yang to refer to the hypothesis of body's physiology and pathology and prevention and treatment effects, given an empirical analysis a feasible way of medicine and philosophy separation and yin and yang turning to medicine; displayed the guidance of new idea and to show the scientific connotation and scientific value of the theory of traditional Chinese medicine.

Objective To observe the effect of MG132 on the expression of extracellular regulated kinase 1/2 (ERK1/2) and connective tissue growth factor (CTGF) in rat peritoneal mesothelial cells (RPMCs) induced by high glucose.Methods RPMCs were isolated,cultured and passaged by trypsin,then identified.The second generation of cultured RPMCs were used in the experiment.RPMCs were divided into normal control group,high glucose (1.5%,2.5%,4.25%) for 24 hours,high glucose (2.5%) for 0,12,24,48 hours,incubated with MG132 (0.5,1,2 μmol/L) for half an hour and then with high glucose (2.5%) for 24 hours.ERK1/2 protein was detected by Western blotting,and CTGF protein in supernatant was detected by ELISA.Results Compared with the control group,the expression of p-ERK1/2 was significantly increased in the groups stimulated by high glucose (P <0.01),reached the peak at 24th hour (P < 0.01),and then the expression decreased at 48th hour,but still was higher than that in the normal control group (P < 0.01).CTGF protein expression of RPMCs induced by high glucose increased,in time-and dose-dependent manner (P < 0.05).MG132 could significantly decrease the expression of ERK1/2 and CTGF induced by high glucose (P<0.05).Conclusions MG132 can decrease the expression of p-ERK1/2 and CTGF in RPMCs induced by high glucose.The ubiquitin proteasome pathway participates in the development of peritoneal fibrosis,and blocking the way may contribute to the prevention of peritoneal fibrosis.
