Objective:To evaluate the bioequivalence of two kinds of domestic nimesulide granules in healthy volunteers. Meth-ods:In self-control and two-way crossover design, 18 healthy male volunteers were divided into two groups randomly. Each subject was given 100 mg test or reference nimesulide granules with single dose. The concentration of nimesulide in plasma was determined by HPLC. The concentration of nimesulide in plasma was calculated and compared statistically to evaluate the bioequivalence between the two kinds of granules by DAS 2. 1 software. Results:The main pharmacokinetic parameters of test and reference preparations were as follows:Cmax was(9. 28 ± 2. 05) and(9. 41 ± 2. 31)μg·ml-1;Tmax was(3. 50 ± 1. 86)and(3. 56 ± 1. 65)h;T1/2 was (3. 43 ± 0. 85) and(3.38 ±0.68)h;AUC0-24 was(77.78 ±18.42)and(81.69 ±23.50)μg·ml·h-1;AUC(0-∞) was (79.07 ±19.21)and(82.92 ± 24. 11)μg·ml·h-1, respectively. The 90% confidential interval of ln(AUC0-24), ln(AUC0-∞) and ln(Cmax) of the test preparation was 90. 7%-107. 9%,90. 6%-111. 2% and 90. 7%-103. 0%, respectively. The relative bioavailability was (96. 7 ± 37. 6)%. Con-clusion:The two nimesulide granules are bioequivalent.

Objective:To investigate the effect of donor lymphocyte infusion (DLI) by intra-bone marrow (IBM) or intravenous (IV) on the incidence of graft-versus-host disease(GVHD) after allogeneic peripheral hematopoietic stem cell transplantation (allo-PBSCT).Methods:Female C57BL/6 mice as recipients received total body irradiation (TBI) on day 0,followed by injection of peripheral hematopoietic stem cells from mobilized male BALB/c with granulocyte-colony stimulating factor (rhG-CSF),and DLI was performed via IV or IBM.The extent of GVHD was compared in recipients received allogeneic IBM-DLI with those received IV-DLI.The percentage of donor-derived cells and CD4~+CD25~+ regulatory T cells (Tregs) was detected by flow cytometry.14 days after DLI,the levels of IL-4 and interferon (IFN)-γ were tested by ELISA.Results:It was found that the frequency and severity of GVHD were reduced in IBM-DLI compared with that of IV-DLI (P＜0.01).7 days after transplantation,the percentage of H-2~d-positive cells was over 95% in all surviving transplanted mice;and 14 days after transplantation,the percentage of Tregs detected as CD4~+CD25~+ was significantly higher in recipients treated with IBM-DLI than those treated with IV-DLI(P＜0.01).Compared with that of the recipients in IBM-DLI group,the level of IL-4 was significantly decreased,while the level of IFN-γ were elevated in group IV-DLI (P＜0.01).Conclusion:IBM-DLI could induce the proliferation of Tregs and the Th polarizing to Th2,resulting in decreasing the incidence and alleviating severity of GVHD after allo-PBSCT.

Objective To investigate the predictive value of class Ⅲ β-tubulin protein expression in tumor tissue for the efficacy of taxol combined chemotherapy in stage Ⅲ s/Ⅳ gastric carcinoma patients.Methods Tumor biopsy samples were obtained and class Ⅲ β-tubulin protein expression were examined by immunohistochemical staining before chemotherapy.According to different expression of class Ⅲ β-tubulin,the patients were divided into two groups,group A(low expression of class Ⅲ β-tubulin),group B(high expression of class Ⅲ β-tubulin).The patients were assigned to be received 4 to 6 cycles of Taxol and S-1 chemotherapy regimens and followed up until death or lost.Response rate(RR),overall survival(OS)and time to tumor progression(TTP)were assessed.Results There was no significant difference in clinical characteristics among patients with different expression rate.The RR was higher and TIP was longer in group A than in group B(53.3 ％ vs 36.7 ％,198 days vs 146 days,P ＜ 0.05 respectively),and no significant differences of OS in two groups(P ＞ 0.05).Conclusion The expression level of class Ⅲ β-tubulin in tumor tissue is probably a predictor for the efficacy of taxol in gastric cancer patients,taxol combined chemotherapy is more suitable for patients with lower expression of class Ⅲ β-tubulin.

Aim To investigate and compare the phar-macokinetics of doxapram injection in healthy subjects of different Chinese nationalities including Han, Mon-golian, Korean, Hui and Uigur, and the influence of gender,in order to provide instruction and help for the usage of doxapram for both clinic and remedy of battle wound. Methods An HPLC-UV method was used to determine the plasma concentration of doxapram. Fifty healthy subjects ( five males and five females of each nationality) were recruited for the study. A single dose of 50 mg doxapram was administered intravenously to the healthy subjects, and blood samples were collected at various predetermined time points. The pharmacoki-netic parameters were calculated by DAS software and were compared by SPSS 13. 0 software, in order to as-sess the influence of nationality or gender on pharmaco-kinetics of doxapram. Results The results indicated that the pharmacokinetic profile of doxapram in vivo could be described as two-compartment model. The main pharmacokinetic parameters for Han, Mongolian, Korean, Hui and Uygur were as follows: Cl ( 0. 25 ± 0. 11 ) , ( 0. 33 ± 0. 11 ) , ( 0. 27 ± 0. 07 ) , ( 0. 26 ± 0. 06) and (0. 39 ± 0. 25) L·h-1 ·kg-1 , while Cmax (1. 55 ± 0. 52 ) , ( 1. 02 ± 0. 30 ) , ( 1. 31 ± 0. 47 ) , (1. 48 ± 0. 46 ) and ( 0. 99 ± 0. 35 ) mg · L-1 . The AUC0-12. 5 , AUC0-∞ and Cmax of Chinese Han were sig-nificantly higher than those of Uigur and Mongolian ( P<0. 05 ) , while there was no significant difference in other parameters ( P>0. 05 ) . There were statistically significant differences in Vc , Vd and CL between young males and females ( P < 0. 05 ) . Conclusion The large inter-individual variation in the main pharmacoki-netics suggests the dosage of doxapram should be ad-justed for different nationalities for both clinic and rem-edy of battle wound.

Objective To study the clinical effect of Self-made Sanjin-Weiwei decoction for patinets with upper urinary tract calculi after extracorporeal shock wave lithotripsy (ESWL). Methods A total of 200 patients with upper urinary tract calculi after ESWL in our hospital from January 2015 to Octomber 2016 were enrolled in this study. The subjects were divided into the control group (n=100) and the treatment group (n=100) randomly. The control group were treated with conventional treatment after ESWL, and the treatment group were treated with conventional treatment plus the Self-made Sanjin-Weiwei decoction after ESWL,and the two groups were treated for 45 days. The clinical effects of both groups were compared. The first time average row stone time and renal colic average frequency of both groups after treatment was compared. The stone platoon net rate of both groups after 1 month, 2 months, 3 months were compared. The incidence of adverse reactions, like dry mouth, nausea, painful urination, blood in urine, of both groups during the treatment were compared. Results The total effect rate of the treatment group was 86.0%, significantly higher than 62.0% of the control group(χ 2=14.969,P<0.001).The first time average row stone time(4.18 ± 1.30 d vs.7.52 ± 2.08 d,t=13.617)and renal colic average frequency(0.67 ±0.21 vs.1.55 ±0.87,t=9.833)of the treatment group were significantly lower than the control group (P<0.05). The stone platoon net rate of the treatment group after 1 month (93.0% vs.74.0%,χ 2=13.101),2 months(98.0% vs.82.0%,χ 2=14.222),3 months(100.0% vs.84.0%,χ 2=17.391)were significantly higher than the control group (P<0.05). The incidence of adverse reactions (7.0% vs. 15.0%, χ2=4.735)of the treatment group were significantly lower than the control group(P<0.05).Conclusions The Self-made Sanjin-Weiwei decoction for patinets with upper urinary tract calculi after ESWL has a good effect and low incidence of adverse reactions, can reduce the renal colic and improve the stone platoon net rate.
