OBJECTIVE:
To investigate the characteristics and influencing factors leading to sudden cardiac death (SCD) of incarcerated prisoners.
METHODS:
Seventy-five SCD cases of prisoners between 2000 and 2013 in Henan province were collected, and environment, psychological and physical factors were retrospectively analyzed. Combined with histopathological results, specific factors of SCD were also studied.
RESULTS:
In the 75 cases, 21 cases (28%) had definite chronic past medical histories, and 75 cases (100%) had cardiovascular disease confirmed by autopsy.
CONCLUSION
Due to presence of the potential cardiac diseases, special incarcerated environment, psychological stress, and body-restraint might be the precipitating factors in SCD of those prisoners.

Miscanthus sinensis Anderss is a perennial C4-grass. It is a promising bioenergy plant, which has been proposed as general feedstock for biomass and lignocellulosic biofuel production. In this study, the flower and leaf buds transcriptomes of Miscanthus sinensis Anderss were sequenced by the platform of Illumina HiSeq 2000. In total 98 326 Unigenes were generated by de novo assembly with an average length of 822 bp and N50 of 1 023 bp. Based on the NR, NT, Swiss-Prot, KEGG, GO and COG databases (Evalue < le-5), 74 134 (75.40%) Unigenes were annotated. A total of 45 507 Unigenes were mapped into different GO terms. In KEGG pathways identification, 36 710 sequences were assigned to 128 KEGG pathways. Sorghum bicolor (37 731, 60.86%), Zea mays (16 258, 26.22%), and Oryza sativa (3 065, 4.94%) showed high similarity to Miscanthus sinensis Anderss. And 24 photosynthesis-related enzyme genes were identified. The result provides a foundation for further characterizing the functional genes in Miscanthus sinensis Anderss.

The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor that regulates gene expression in a range of cells, including immune and epithelial cells. AhR signaling plays important roles in the immune system in both health and disease states. Tapinarof is a first-in-class small-molecule topical therapeutic AhR modulating agent launched for the treatment of psoriasis. To improve the activity and chemical stability of Tapinarof, a series of 2-phenylchromen-4-one derivatives were designed, synthesized and evaluated as novel AhR agonists. Compounds

OBJECTIVETo explore the killing effect of the mutant herpes simplex virus thymidine kinase (HSV-sr39tk) and its wild-type (HSV-tk) mediated by lentiviral vector on T lymphocytes in vitro and compare T cell survival rate after GCV or ACV treatment.
METHODSThe three-plasmid lentiviral vector system including packaging plasmid DeltaNRF, envelope plasmid VSV-G and vector plasmid (pTK151 + HSV-sr39tk or pTK151 + HSV-tk) were cotransfected into human embryonic kidney 293T cells using modified calcium phosphate precipitation methods. The packaged virus was harvested 72 h later. The survival of T cells expressing HSV-sr39tk or HSV-tk was measured by MTT assay after 4 day-culture against a gradient of GCV or ACV concentrations.
RESULTSThe three plasmids were effectively cotransfected and a high titre of lentivirus was obtained (2 x 10(6) IU/ml). 39tk(+) T cell survival rates declined promptly when the prodrug GCV/ACV concentrations increased from 0 micromol/L to 10 micromol/L. The T cell survival rates in GCV group declined from (96.04 +/- 3.23)% to (36.76 +/- 4.38)% while in ACV group from (97.31 +/- 4.61)% to (43.75 +/- 8.99)%. However, when GCV/ACV concentrations were more than 10 micromol/L, further decline of 39tk(+) T cell survival rates became unobvious. The growth rate of 39tk(+) T cell exposed to GCV or ACV was obviously lower than that in un-transfected T cells (P < 0.05). Tk(+) T cells were sensitive to GCV (P < 0.05), but not to ACV (P > 0.05). There was a significant difference in killing effects between 39tk(+) T cell + GCV group and tk(+) T cell + GCV group (P < 0.05).
CONCLUSIONThe lentiviral vectors containing HSV-sr39tk gene could infect T lymphocytes effectively and stably without affecting the proliferation of the transduced cell. In contrast to HSV-tk gene, T cells infected HSV-sr39tk were more sensitive not only to GCV but also to ACV.

OBJECTIVETo construct a recombinant lentiviral vector (pXZ208-BDDhFVIII) mediating B-domain-deleted human coagulation factor VIII (BDDhFVIII) gene and investigate its expression in HLF, Chang-Liver and MSC cells.
METHODSBDDhFVIII gene fragment was separated by endonuclease digestion and was cloned into the multiple cloning sites of pXZ208 to construct a recombinant lentiviral vector pXZ208-BDDhFVIII. Viral particles were prepared by means of three-plasmid cotransfection of 293T package cells by calcium phosphate precipitation. After infection, the coagulant activity of human FVIII in the culture medium of 293T, HLF, Chang-Liver and MSC cells was assayed by one-stage method. The gene transduction efficiency was assayed by flow cytometry (FCM). Furthermore, PCR was performed to test the integration of BDDhFVIII.
RESULTSThe infection rates of HLF, Chang-Liver and MSC were (74.52 +/- 7.57)%, (27.24 +/- 6.53)% and (42.34 +/- 5.84)% respectively. The activities of FVIII in supernatants of HLF, Chang-Liver and MSC were (54.1 +/- 5.6)%, (22.5 +/- 2.9)% and (12.5 +/- 2.7)% respectively. BDDhFVIII gene integration was detected in all the infected cells.
CONCLUSIONThe recombinant lentiviral vector pXZ208-BDDhFVIII was successfully constructed and efficiently integrated into target cells to express human FVIII activity in vitro.

OBJECTIVETo investigate the h4 allele (C35T) frequency of alpha-1,2-fucosyltransferase gene in Chinese population.
METHODSThe polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method for identifying C35T variant was established by using PCR to amplify a 125 bp FUT1 gene fragment, including C35T variant sequence, and the PCR product was digested by Hae III restriction enzyme. One hundred and fifty-eight random samples from Chinese blood donor were screened by PCR-RFLP.
RESULTSAmong 158 Chinese individuals with normal ABO and H blood group phenotypes, 8 and 83 were homozygous with 35T/T and 35C/C, respectively, while 67 were heterozygous with 35C/T. The allele frequencies were compatible with Hardy-Weinberg equilibrium.
CONCLUSIONThe C35T substitution of FUT1 gene is not a mutation which gives rise to a non-functional h allele responsible for para-Bombay phenotype but a single nucleotide polymorphism in Chinese population.

OBJECTIVETo establish strategies for preventing graft versus host disease (GVHD) and reducing treatment associated morbidity while preserving graft versus leukemia (GVL) effect in nonmyeloablative allogeneic bone marrow transplantation (allo-BMT), with or without donor lymphocyte infusion (DLI) after BMT.
METHODS3 x 10(7) bone marrow cells mixed with 1 x 10(7) spleen cells from the same BALB/c mouse were transplanted into the nonablative irradiated inbred 615 mouse which received a single subcutaneous injection of 1 x 10(6) L615 leukemia cells three days before. The experiments were designed as follows (ten mice in each group): myeloablative BMT control group (group A), nonmyeloablative conditioning without BMT group (group B), nonmyeloablative BMT group (group C), and nonmyeloablative BMT + DLI group (group D). GVL effects were assessed by survival time, white blood cell count and L615 cells in peripheral blood and histologic changes. GVHD was assessed by signs of weight loss, ruffled fur, diarrhea and histologic changes of skin, liver and small intestines. Chimerism was detected by cytogenetic analysis and PCR technique.
RESULTSThe survival time of group A, B, C and D was (20.3 +/- 13.4), (15.9 +/- 1.1), (21.6 +/- 1.7) and (37.8 +/- 2.0) days, respectively, being no significant difference between group A and group C (P > 0.05). The survival time of group C was longer than that of group B (P < 0.01). And among group B, C and D, group D had the longest survival time (P < 0.01). GVHD signs and histologic changes were observed in 60% of control group mice at + 14 day, but none of group C and group D. 40% of mice in group A died of treatment associated morbidity within two weeks, but none in group C and group D. Allogeneic chimerism was kept in group A, but excluded gradually in group C.
CONCLUSIONGVL effect seems preserved in nonmyeloablative BMT mice, but weaker than that in myeloablative BMT mice. GVL effect seems to be enhanced by DLI after nonmyeloablative BMT. GVHD and transplantation associated morbidity seems to be reduced in nonmyeloablative BMT.
