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 .
2.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.

Psychological behavior training curriculum in military medical college was recon-structed after investigating psychological behavior training class in 45 military colleges. The measures taken included:establishing scientific management model, optimizing the teaching object and content, reforming the teaching method and improving multiple assessment methods. Self rating symptom scale symptom checklist 90(SCL-90) was used to test the psychological condition of students before and af-ter the teaching experiment. Results showed that seven factors were of statistical significance for stu-dents. Factors of fear and paranoia were statistically insignificant.

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.

Objective:To establish an HPLC method with post-column derivation for the determination of aflatoxin B1 in edible vegetable oil. 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 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.

Aim To study the pharmacokinetics characteristics of galanthamine hydrohromide sustained release tablets and conventional tablets in healthy volunteers after a single and multiple oral doses. MethodsA single and multiple oral doses of galanthamine hydrohromide sustained release tablets and conventional tablets were given to 20 healthy male volunteers in a randomized cross-over study. We developed an LC-MS assay using naloxone as the internal standard to determine the plasma concentrations of galanthamine, calculate the pharmacokinetic parameters and evaluate the relative bioavailability and sustained release characteristics of galanthamine hydrohromide sustained release tablet. Results The pharmacokinetic parameters of the sustained release tablet and conventional tablet obtained from the single-dose study were as follows: the HVD_12 C_max(time span during which the plasma concentration is at least half of the C_max value)were (15.4?1.7) h and (5.4?2.5) h, the retard quotients (R△,the HVD_12 C_max ratio of sustained release tablets to conventional tablets) of sustained release tablet was 3.4?1.4, the T_max were (4.4?1.5) h and (1.3?1.2) h, the C_max were (27.5?2.9) ?g?L-1 and (53.7?12.7) ?g?L-1.Results showed significant sustained release characteristics of the sustained release tablet. The relative bioavailability of the sustained release tablet was (95.9?14.2) %。The pharmacokinetic parameters of the sustained release tablet and conventional tablet obtained from the multi-dose study were as follows: the T_max were (3.0?1.6) h and (0.9?0.3) h,the CSS_max were (58.8?9.4) ?g?L-1 and (52.0?6.9) ?g?L-1,the CSS_min were (16.2?4.0) ?g?L-1 and (22.5?5.0) ?g?L-1,the C_av were (39.0?3.9) ?g?L-1 and (37.1?5.0) ?g?L-1,the DF were 1.1 ?0.3 and 0.8?0.1, respectively. Results of two one-side t test showed that AUC_SS、CSS_max、C_av of two tablets were bioeqivalent. Conclusion Results showed that the sustained release tablet and the regular tablet were bioequivalent in absorbed extent, and the sustained release tablet exhibited a good retarding effect in release.
