Aim To investigate Jaridonin′s selective killing of cancer cells and explore the related molecular mechanism. Methods After treatment by Jaridonin for 24 h, the effect of Jaridonin on the cell viability was examined using MTT assay. The effect of Jaridonin on cytomorphology and mitochondrial membrane poten-tial (Δψm) was observed by a fluorescence microsco-py. The apoptosis of cell lines treated with Jaridonin, as well as the level of reactive oxygen species ( ROS ) was analyzed by flow cytometry. Expression of the pro-teins related with mitochondria apoptosis pathways was detected by Western blot. Results Jaridonin caused strong antiproliferative and apoptotic effects on MGC-803 cells, but there were not remarkable effects on GES-1 cells. Furthermore, the expression of Bax was up-regulated, and the release of cytochrome c from mi-tochondria to cytosol was also promoted in MGC-803 cells treated by Jaridonin. The cleavage of caspase-3 in MGC-803 cells was also observed. Jaridonin increased persistently intracellular levels of ROS in MGC-803 cells, whereas the level of ROS in GES-1 rose in the first stage, and then decreased, and dropped to the basic level after 6 h. More interestingly, Jaridonin-in-duced ROS accumulation and the inhibition of MGC-803 cell proliferation were almost completely attenuated in the presence of GSH. Conclusions Jaridonin se-lectively kills cancer cells and induces apoptosis in MGC-803 through ROS-mediated mitochondrial dam-age.

This article reports the results of tandem mass spectrometry and the mutation features of the ETFDH gene for an infant with multiple acyl-CoA dehydrogenase deficiency. The results of tandem mass spectrometry showed that C14 : 1, C8, C6, C10, and C12 increased. Exon sequencing was performed on this infant and his parents and revealed double heterozygous mutations in the ETFDH gene of the infant: c.992A>T and c.1450T>C. The former was inherited from his mother, and the latter was inherited from his father. c.1450T>C was shown to be the pathogenic mutation in the HGMD database. PolyPhen2, SIFT, and PROVEAN all predicted that the novel mutation c.992A>T might be pathogenic, and the mutant amino acids were highly conserved across various species. The findings expand the mutation spectrum of the ETFDH gene, and provide molecular evidence for the etiological diagnosis of the patient with multiple acyl-CoA dehydrogenase deficiency as well as for the genetic counseling and prenatal diagnosis in the family.

OBJECTIVETo investigate the effects of simple hypobaric hypoxia on parameters of hematology and blood rheology in order to establish a rat model of simulated high altitude polycythemia (HAPC) for the study of pathophysiologic mechanisms and medical prevention and treatment of HAPC.

METHODSForty-eight male Wistar rats were randomly divided into three normal control groups and three hypoxia model groups. Normal control group rats were bred in normoxia conditions, and hypoxia group rats were subjected to hypoxic exposure for 8 hours per day at simulated 5 500 m high altitude in a hypobaric chamber. After hypoxic exposure for 2, 4, 12 weeks, one group of normal control and hypoxia model rats were killed and blood was collected, respectively. Then parameters of erythrocyte and blood rheology were examined.

RESULTSMucous membrane of hypoxia model rats showed obviously cyanosis after 2 weeks hypoxic exposure. Hemoglobin concentration of hypoxia model rats were beyond 210 g/L after 2 weeks, 4 weeks and 12 weeks hypoxia exposure and significantly increased than that of normal control rats respectively. Besides, RBC counts, hematocrit, whole blood viscosity, erythrocyte aggregation index of hypoxia model rats were all notably higher than those of normal control rats respectively.

CONCLUSIONA rat model of high altitude polycythemia can be rapidly established by hypobaric hypoxia exposure at simulated 5 500 m high altitude for 8 hours daily.

Objective:To investigate the polymorphisms at HLA-A,-B,-DRB1 loci in Dalian Han population. Methods: A total of 10 000 unrelated marrow donors who live in Dalian were genotyped by SBT and SSO methods. Haplotype frequencies and linkage dis-equilibrium values were calculated by ARLEQUIN software,and DA genetic distances between populations were calculated by poptree2 software. Results: A total of 18 HLA-A alleles, 32 HLA-B alleles and 13 HLA-DRB1 alleles were found in Dalian Han population. HLA-A?02 (31. 65% ),B?40(14. 84% ) and DRB1?15(15. 82% ) occurred most frequently. A?30-B?13-DRB1?07 (4. 56% ) was determined to be the most common three-locus haplotype and the second predominant haplotype was A?02-B?46-DRB1?09 ( 2. 43% ) . A ?30-B ?13 ( 6. 00% ) and B ?13-DRB1 ?07 ( 59. 89% ) were the most common two-locus haplotypes. Moreover,A?33-B?58 and B?13-DRB1?07 were strongest haplotypes with the linkage disequilibria values 0. 336 6 and 0. 665 1,respectively. In China,the closest genetic distances were found with Heilongjiang (0. 001) followed by Jilin (0. 002) and Shandong (0. 002),the furthest was found with Taiwan (0. 047). Compared with other populations worldwide,the closest genetic distances were found with Thailand (0. 029) and Korea (0. 03),the furthest was found with Italy (0. 183). Conclusion: Dalian Han population had rich polymorphism at HLA-A,-B,-DRB1 loci,and the distribution of HLA-A,-B and-DRB1 was in line with the charac-teristics of the northern population.

AIM:To explore the effect of sex on the formation of chronic pancreatitis(CP)by comparing the differences in L-arginine-induced CP model between male and female mice.METHODS:Male(n=42)and female(n=42)Kunming mice were randomly divided into 4 groups:female control group, female CP group, male control group and male CP group(n=18 in each control group, n =6 at each time point; n=24 in each CP group, n=8 at each time point).The mice in CP groups were intraperitoneally injected with 20%L-arginine(3 g/kg,twice/d,1 d/week).After modeling for 2 weeks,4 weeks and 6 weeks,the mice were anesthetized and sacrificed.The morphological changes and the degree of fibrosis in the pancreas were observed by HE and Masson staining.The positive expression rate of F4/80 in the pancreatic tissues was observed by the method of immunohistochemistry.The mRNA expression of interleukin-6(IL-6), α-smooth muscle actin(α-SMA)and fibronectin(FN)in the pancreas were detected by real-time PCR.The protein of pancreas was extracted to detect the expression of α-SMA and FN by Western blot.RESULTS:At 2 weeks,4 weeks and 6 weeks after intraperitoneal injection of L-arginine, the pancreatic tissues were obviously injured and exhibited different degrees of fibrosis in female and male CP groups.At the same time,there were significant differences in the degree of pan-creatic injury between male and female mice,and the degree of pancreatic lesion in the male mice was significantly more severe.The positive rate of F4/80 in the pancreas of male CP mice was significantly higher than that in female CP group at the same time point after modeling.At every time point, the mRNA expression of IL-6 in the pancreas was increased in both female and male CP groups,but that in male CP group was higher(P<0.05).The fibrosis indexes,α-SMA and FN, were both highly expressed at mRNA and protein levels after modeling, but compared with the female group, the time of positive expression in male mice was earlier and the expression level was higher(P<0.05).CONCLUSION: The CP model is successfully established by intraperitoneal injection of 20%L-arginine,and a difference in the degree of pathologic alteration in pancreas between male and female mice exists.CP is more effectively induced by L-arginine in male mice,and the degree of fibrosis is more pronounced.The reason may be related to the sensitivity of male mice to L-arginine,causing more serious inflammatory response.Therefore,male mice are more suitable for establishing CP animal model.

Objective: To assess the feasibility of coronary lfow reserve (CFR) detection by SPECT myocardial perfusion imaging using a self developed software with preliminary clinical veriifcation. Methods: CFR calculation software was developed according to Mat lab guide. A total of 16 patients were enrolled including 13 male and 3 female at the mean age of (58±11) years . CAG conifrmed that 25 coronary branches were with stenosis>50% and 23 branches were without stenosis. 2-day ATP/rest99mTc-sestamibi dynamic SPECT myocardial perfusion imaging was conducted to detect CFR. First transit counts were used to sketch the interested pulmonary artery segments and to obtain the arterial input curve of contrast agent as total PAC reached to heart. Reconstructed short-axis images were divided into 3 sections to sketch interested territories (ROI) and to obtain RMC at each territory. Estimated CFR was expressed by the ratio of MBF=RMC/PAC followed by calculating the ratio of MFR=MBFstress/MBFrest. Results: The difference between simulated value and true value could be ignored which conifrmed that our program may accurately measure CFR. The reproducibility by different operators (r=0.986) and the same operator (r=0.983) was good. CFR value in non-stenosis branches were higher than stenosis branches (1.28 ± 0.19) vs (1.10 ± 0.27),P=0.008 and CFR value in stenosis branches was negatively related to stenosis degree (r=-0.5,P=0.02). Conclusion: Our self developed software is reliable for CFR detection by SPECT myocardial perfusion imaging; preliminary study showed good application prospect in clinical practice.
