OBJECTIVETo study the absorption kinetics of dehydrocavidine in rats' stomachs and intestines.
METHODThe absorption kinetics was investigated by the in situ perfusion in rats and the concentrations of drug perfusion solutions were determined by HPLC.
RESULTThe hourly absorption percentages of dehydrocavidine in stomach, small intestine were 8.88%, 2.08%, respectively. Although the absorption rate constants of dehydrocavidine in duodenum and jejunum are more than that in ileum and colon, there is no significance difference between them. The absorption rate constants kept at the same level when the concentrations of drug perfusion solution are at middle and high level. The increase of the pH of perfusion solution didnt significantly affect the absorption rate constants of the drug.
CONCLUSIONDehydrocavidine was absorbed poorly at stomach and all segments of intestine in rats, but the absorptions in stomach are better than intestine. Dehydrocavidine was absorbed mainly via passive transport mechanism between middle and high concentration levels.

Objective To comprehensively evaluate the curative effect and adverse effects of rituximab plus cyclophosphamide, vincristine, doxoruhicin and prednisone(R-CHOP) chemotherapy and CHOP chemotherapy alone on the treatment for low and moderate malignant B cell non-Hodgkin lymphoma (NHL). Methods By the application of the systematic review method of Cochrance International Collaboration, the world-wide randomized controlled trials (RCT) on the comparison between different curative effects of R-CHOP and CHOP chemotherapy alone on the treatment low and moderate malignant B cell NHL was collected and the study results was evaluated systematically. Results Seven RCT studies involving 1569 patients and had no heterogeneity between themselves (χ=5.31,P=0.50). The baseline of patients characteristics was comparable in all the studies. By comparing complete response (CR) rate and adverse effects through fixed effect analysis model, the results showed that R-CHOP was better than CHOP chemotherapy on the treatment for low and moderate malignant B cell NHL(OR =2.22, 95 %CI 1.72-2.85, P <0.000 01), and adverse events of R-CHOP had no significant difference compared with CHOP chemotherapy alone (P>0.05). Conclusion With good curative effect on the treatment low and moderate malignant B cell NHL and without obvious differences from the CHOP chemotherapy alone in adverse effects, R-CHOP chemotherapy should be recommended as the best treatment method for low and moderate malignant B cell NHL And much more well-designed clinical RCT should be made to further prove its clinical effect.

Objective To assess the clinical significance of detecting the immune markers in idiopathic thrombocytopenic purpura (ITP). Methods The frequencies of circulating B cells secreting platelet-specific antibody, platelet-specific antibody, the percentage of T lymphocyte subsets, the percentage of reticulated platelet and the level of thrombopoietin in 64 ITP patients and 31 healthy controls were measured with enzyme-linked immunospot assay (ELISPOT),modified monoclonal antibody immunobilization of platelet antigens assay (MAIPA), flow cytometry and sandwich enzyme-linked innnunosorbent assay respectively. Results Compared with the controls[1.3 ± 0. 5/105 peripheral blood mononuclear cell (PBMC), (0.33±0.06,0.41±0.03), (22.08±4.54)% and (8.19±2.46)%], the frequencies of circulating B cells secreting platelet-specific antibody (7.6±4.6/105 PBMC in acute ITP group, 5.3±3.0/105 PBMC in chronic ITP group), platelet-specific antibody (including the anti-GP Ⅱ b/Ⅲa antibody, anti-GP Ⅰ b/X antibody) (0.51 ±0.11, 0.48±0.06 in acute ITP group; 0.49±0.10,0.46±0.09 in chronic ITP group), the percentage of CD8+ T Lymphocyte (27.09±9.86 ) %, the percentage of reticulated platelet in ITP patients[the megakaryocyte cytosis group (24. 85 ± 19. 18)%, the normal megakaryocyte group (23.89±18.90)%]were significantly increased ( all P<0.05).The frequencies of circulating B cells secreting platelet-specific antibody in acute ITP patients were notably increased (P<0.05) compared to the chronic ITP patients. In T lymphocyte subsets, the percentage of CD3+T lymphocyte and CD4+ T lymphocyte and the ratio of CD4+/CD8+ in the patients with ITP[(60.88±14.59)%, (28.41±10.55)%, 1.18±0.59]were notably decreased than those in the healthy controls [(69.89±6.43)%, (35.38±5.05) %, 1.64±0.29, P<0.05]. There was no apparent difference of the level of thrombopoietin between ITP patients with megakaryocyte cytosis (72. 09 ± 41.64 ) and health controls (75.37± 26. 32, P > 0. 05 ), however, the level of thrombopoietin of ITP patients with normal megakaryocyte apparently increased (118.60±70.72, P<0.05). Conclusion Detecting the frequencies of circulating B cells secreting platelet-specific antibody, platelet-specific antibody, the percentage of T lymphocyte subsets, the percentage of reticulated platelet and the level of thrombepoietin in the patients with ITP may improve the diagnosis and guide clinical therapy.

Aim To study the effects of HiHi and HiLo on the lipid metabolism in rats through blood lipids and fatty acid oxidation in gastrocnemius of rats. Methods Thirty male SD rats were selected by means of adaptive training, and then divided into 3 groups randomly: living low-training low group (LoLo), living high-training high group (HiHi), and living high-training low group (HiLo). The rats ran on a treadmill 60 min a day at the speed of 35 m/min under normoxic condition or 30 m/min under hypoxic condition (13.6% of ambient FIO_2), 6 days a week for 4 weeks. The samples from blood and gastrocnemius were removed 24 hours after the last training by the end of 4-week experiment. TC, TG, HDL and LDL were tested with a full-automatic biochemical analyzer. LPL, leptin and AD were measured using ELISA. Real-time quantitative PCR was adopted to test the expression of PPARa and CPT-1 mRNA in rats' gastrocnemius. Results Compared to the LoLo, TC and TG decreased significantly (P0.05) and LPL and AD increased significantly (P<0.01) in HiHi.' PPARa mRNA and CPT-1 mRNA expressions in gastrocnemius were significantly higher in HiHi(P<0.05) than in LoLo, and significant descent of HDL(P<0.05) and CPT-1 mRNA expression(P<0.01) revealed in HiLo, as compared to the LoLo. Compared to the HiLo, HDL(P<0.05), and LPL, AD and CPT-1 mRNA expression(P<0.01) enhanced in HiHi. Conclusion (l) HiHi was more superior in regulation of blood lipids than LoLo due to increasing of LPL, and could facilitate fatty acid oxidation because of enhancement of CPT-1 mRNA, AD and PPARa mRNA. (2) Comparing to the normoxic training, HiLo had no beneficial effect on the blood lipid metabolism and decreased the fatty acid oxidation in gastrocnemius.(3 )HiHi was more superior in the effeet of HDL thah HiLo due to increasing of LPL, and could facilitate fatty acid oxidation because of enhancement of AD and CPT-1 mRNA.
