OBJECTIVETo study the impact of the chloride channel dysfunction of the cystic fibrosis transmembrane conductance regulator (CFTR) on the cytoskeleton of Sertoli cells in the mouse.

METHODSTM4 Sertoli cells were cultured and treated with CFTR(inh)-172 at the concentrations of 1, 5, 10 and 20 μmol/L for 48 hours. Then the cytotoxicity of CFT(inh)-172 was assessed by CCK-8 assay, the expressions of F-actin and Ac-tub in the TM4 Sertoli cells detected by immunofluorescence assay, and those of N-cadherin, vimentin and vinculin determined by qPCR.

RESULTSCFTR(inh)-172 produced cytotoxicity to the TM4 Sertoli cells at the concentration of 20 μmol/L. The expressions of F-actin and Ac-tub were decreased gradually in the TM4 Sertoli cells with the prolonging of treatment time and increasing concentration of CFTR(inh)-172 (P < 0.05). The results of qPCR showed that different concentrations of CFTR(inh)-172 worked no significant influence on the mRNA expressions of N-cadherin, vimentin and vinculin in the Sertoli cells.

CONCLUSIONThe CFTR chloride channel plays an important role in maintaining the normal cytoskeleton of Sertoli cells. The reduced function and expression of the CFTR chloride channel may affect the function of Sertoli cells and consequently spermatogenesis of the testis.

Due to the diversity of components within the traditional Chinese medicines (TCMs), the release profiles of the components in the TCM dosage forms vary dramatically and no quantification method is available to determine the variance yet. Based upon the principles of Kalman filter method, the authors defined a new parameter, relative chemomic error (epsilon), to evaluate the asynchronous nature of the components in TCMs, and a derivative parameter as synchronization factor (SF) to quantify the synchronicity of the chemome of the TCMs. The average synchronization factor (SF(av)) was accordingly derived to simultaneously quantify the release/dissolution profiles of the multi-components in TCMs. Randomly generated simulation data were processed to demonstrate the chemomic data processing and the methodology. The results indicated that the novel parameter epsilon was well correlated (r = 0.996 8) with the coefficient of variation from the conventional release profiles of all the components. As the asynchronicity was the intrinsic characteristics of the multi-component TCMs, the synchronicity might be a new target of quality control of TCMs. The methods established by this report can be used a quantitative tool for the evaluation of the chemomic release synchronization of TCMs.

OBJECTIVETo transfect a short hairpin RNA (shRNA) against survivin gene into human T lymphoblastic leukemia cell line Jurkat, and to explore the effects on apoptosis and proliferation of transfected cells.

METHODSThe survivin-shRNA expression vector were constructed and transfected into Jurkat cells. Expression of survivin mRNA and protein were assessed by RT-PCR and Western blot analysis respectively. Apoptosis index of transfected Jurkat cells was quantified by flow cytometry. The potential of cell proliferation was described by cell growth curves.

RESULTSIn survivin-shRNA transfected Jurkat cells, survivin mRNA levels were significantly reduced by 66.67% ( transient transfection) and 60.69% ( stable transfection) respectively, compared with that in control-shRNA treated group and PBS treated group (P < 0.05); and the levels of survivin protein were significantly reduced by 63.41% (transient transfection) and 60.18% (stable transfection), compared with that in the two control groups (P < 0.05). Apoptosis index was significantly increased during both transient and stable transfection, respectively [(22. 41 +/- 2.83)% and (20.73 +/- 2.56)% (P < 0.05)]. Survivin-shRNA also inhibited the proliferation of Jurkat cells.

CONCLUSIONSVector-based survivin-shRNA can effectively reduce the expression of survivin gene, induce apoptosis

OBJECTIVETo study the effect of atorfastatin on the cognitive function of patients with vascular cognitive impairment (VCI) and different apolipoprotein E genotypes.

METHODSThe ApoE polymorphism was genotyped by PCR sequencing and the patients were divided into Eepsilon4 carrier (epsilon4+) group (n=24) and epsilon4- group (n=51). All the patients were given 20 mg oral atorfastatin every evening. The indices of TC, TG, HDL-C, LDL-C, as well as the scores of MMSE and clock-drawing test were compared between the two groups before and 24 weeks after the treatment.

RESULTSCompared with those without epsilon4 allele, epsilon4+ patients had obviously increased plasma LDL level and lowered scores of MMSE. Plasma TC, TG and LDL-C were decreased significantly in the two groups after the treatment, and the improvement of TC was greater in patients without epsilon4 allele. The scores of MMSE increased significantly in patients with epsilon4 allele. The improvement in the scores of MMSE and clock-drawing test was greater in epsilon4+ group than in epsilon4- group.

CONCLUSIONAtorfastatin may improve the cognitive function in patients with VCI carrying epsilon4 allele, the effect of which may not be related to lowed blood lipids.

OBJECTIVETo investigate the effects of immature dendritic cells (imDC) expressing chemokine receptor-7 (CCR7) on acute graft-versus-host disease (aGVHD) in allogeneic bone marrow transposed (allo-BMT) mouse model.

METHODSWe constructed the lentiviral vectors carrying mouse CCR7 gene and infect imDC effectively in vitro. GVHD model was established with C57BL/6(H-2b) donor mice and BALB/c (H-2d) recipient mice. After irradiation, recipients were injected with donor bone marrow and spleen cells along with CCR7-modified dendritic cells. Mice were randomized into irradiation, transplant control, pXZ9-imDC (empty vector control) and CCR7-imDC groups. Survival, GVHD score, histopathological analysis and plasma levels of inflammatory cytokines were observed.

RESULTSThe mean survival in irradiation, transplantation, pXZ9-imDC and CCR7-imDC groups were (8.20±1.48)d, (12.20±2.78)d, (20.70±6.01)d and (27.5±7.55)d respectively. The survival in CCR7- imDC group was significantly improved compared with other groups (P<0.05). GVHD scores in transplantation, pXZ9-imDC and CCR7-imDC groups were (6.90±1.66), (5.60±0.97) and (4.10±1.79) respectively. CCR7-imDC group had significantly lower GVHD score and minor tissue damages shown by histopathological analysis than the other groups. Plasma IFN-γ level increased and reached the peak at +10 day in transplant group, while it gradually decreased in pXZ9-imDC and CCR7-imDC groups, and then reached the nadir at +20 day post-allo-BMT, with the lowest level in CCR7-imDC group (P<0.01). Plasma IL-4 decreased in transplant group, while it gradually increased in pXZ9-imDC and CCR7-imDC groups and reached the highest level at + 10 day in CCR7- imDC group (P<0.01). The 95%-100% of H-2b positive cells in recipient mice on + 30 day post-allo-BMT demonstrated the complete donor- type implantation.

CONCLUSIONGenetically modified immature DC by CCR7 gene could alleviate damages by GVHD and prolong survival of recipient mice after allo-BMT.

Yinqiaojiedu honeyed pills were equally divided into 1/4, 1/8, 1/12, and 1/16 parts. The materiomics release rates within 12 h of the intact Yinqiaojiedu honeyed pills and the divided granules were determined by the paddle method with a rotate speed at 100 r x min(-1), and the materiome was quantified by UV-scan and Kalman filter methods. The intact Yinqiaojiedu honeyed pills behaved typical sustained release profiles, while the well-divided portions also maintained a sustained release profile over 2-4 h. The release rates were well correlated with the extents for the divisions of the pills. The Weibull distribution parameters, Td and T50, were reduced in line with the particle size, indicating that the ways of administration of the pills may play a role in the in vivo pharmacokinetics of the pills. The visualization results showed obvious difference of materiomic release synchronicities between the intact pills and the equally divided particles, and the divisions enhanced the asynchronization. Therefore the novel theory of materiomic release/dissolution kinetics of traditional Chinese medicines (TCMs) quantitatively proved the traditional dosage form, namely, honeyed pills, as a prototype of the sustained-release dosage form with a visualization of the scientific connotation to the old saying in the classics of TCM, Pills, the moderate ones in action. In terms of materiome increase for each period of the release profiles, the materiomic release synchronicity was visually demonstrated. The novel theories provided methodological basis for the evaluation of traditional dosage forms and the design of the modern drug delivery systems for TCMs.

OBJECTIVETo evaluate the biological effect on the synthesis of the extracellular matrix (ECM) in the cultivation of adult degenerative nucleus pulposus cells using the stiring microcarrier system in vitro.

METHODSThirty-four specimens were collected after intervertebral fusion operations of the patients with intervertebral disc herniation diseases from September 2005 to May 2009. The specimens were then randomly allocated into 2 groups for in vitro cultivation: monolayer culture group and microcarrier culture group. On the exponential phase, SP-ABC immunohistochemical staining and Western blot quantitative analysis were conducted in the two groups to detect the collagen type I and II. Proteoglycan contents of two groups in different growth phases were detected with (35)S-sulfate incorporation assay.

RESULTThe expressions of collagen type I and II in microcarrier culture group were significantly higher than those in monolayer culture group: SP-ABC immunohistochemical staining (collagen type I: 32.5 ± 4.4 vs. 15.2 ± 1.2, t = 2.871, P < 0.01; collagen type II: 43.6 ± 4.1 vs. 23.1 ± 2.2, t = 2.375, P < 0.05); Western blot quantitative analysis (collagen type I: 0.62 ± 0.08 vs. 0.50 ± 0.06, t = 3.327, P < 0.01; collagen type II: 1.46 ± 0.08 vs. 0.86 ± 0.04, t = 2.453, P < 0.05). Nucleus pulposus cells cultivated in stiring microcarrier system showed significantly increased proteoglycan synthesis than monolayer culture group does on both exponential phase and stationary phase (exponential phase: 34 821 ± 312 vs. 21 046 ± 673, t = 2.134, P < 0.05; stationary phase: 45 134 ± 175 vs. 32 193 ± 713, t = 2.801, P < 0.01).

CONCLUSIONSThe expression of collagen type I, II and proteoglycan of adult degenerative nucleus pulposus cells are positive regulated by the stiring microcarrier system, which can be used in the mass amplification of the adult degenerative nucleus pulposus cells.
