Objective To investigate the effects of macrophage inflammatory protein-1α (MIP-1α) combined with molecule 4-1BB L on the tumorigenicity of hepatocellular carcinoma cells in vivo. Methods Mouse MIP-1α (mMIP-1α) expressed Hepa 1-6 cells were transfected with m4-1BBL recombinant retrovirus, the anti-histidinol cells clones were selected and amplified. The expression of m4-1BB L was confirmed by flow cytometry. The growth curve of Hepa 1-6 cells transfected with mMIP-1α and m4-1BBL alone or together was drawn and compared. C57B/L Mice were randomly divided into 7 groups, 9 mice in each group, injected with mMIP-1α+m4-1BB L Hepa 1-6 cells, m4-1BB L Hepa 1-6 cells, mMIP-1α Hepa 1-6 cells, Hepa 1-6 cells, pLXSHD Hepa 1-6 cells or PBS respectively. The tumorigenicity of hepatocellular carcinoma cells and the mice survival rate were compared between each groups. Results Hepa 1-6 mMIP-1α+m4-1BB L cells which expressed both mMIP-1α and m4-1BB L were successfully established. The expression of mMIP-1α and m4-1BB L alone or together did not affect the growth curve of Hepa 1-6 cells. Observed for 5 weeks, no tumor developed in Hepa 1-6 mMIP-1α+m4-1BB L injected mice. The tumorigenicity of Hepa 1-6 mMIP-1α+m4-1BB L was lower than that of Hepa 1-6 mMIP-1α or Hepa 1-6 m4-1BB L in vivo. The survival rate of Hepa 1-6 mMIP-1α+m4-1BBL injected mice(9/9) was higher than that of Hepa 1-6 m4-1BB L injected mice (6/9)or Hepa 1-6 mMIP-1α injected mice (1/9). Conclusion Chemokine MIP-1α combined with costimulatory 4-1BB L lowered the tumorigenicity of hepatocellular carcinoma cells in vivo, and prolonged the mice survival period.

Objective To analyze the relationship between the change of serum vascular epidermis growth factor(VEGF) level and curative effect of pancreatic cancer treated by gamma rays, and evaluate it clinical significance. Methods The serum VEGF level of thirty patients with pancreatic cancer treated by gamma rays were determined before and one month after treatment. The relationship between curative effect,survival, life quality and the serum VEGF level was analyzed. Results The serum VEGF level of 30 cases before treatment was (624.1 ± 144.3) pg/ml, whereas one month after treatment it was (279.3 ± 83.4) pg/ml(P ＜0.01 ). In the 19 patient whose serum VEGF level decreased by more than 50%, CR + PR was gained in 18 patients, improved quality of life in 7 patients, and in the 11 patient whose serum VEGF level decreased by less than 50%, CR + PR in 7 patients, improved quality of life in 1 patient( P = 0.012, P = 0. 028). In 24patients who completed 2 years follow-up, 11 of 15 patients whose serum VEGF level decreased by more than 50% survived more than 1 year, which was higher than that of the patients whose serum VEGF level decreased by less than 50%. Conclusions The serum VEGF level decreased significantly after gamma rays treatment and the extent of decrease could be used as a surrogate to evaluate the therapeutic efficacy.

Objective: To investigate the effects of andrographolide on extracellular signal-regulated kinase 1/2 (ERK1/2) signaling pathway and tumor necrosis factor-α (TNF-α) expression in lipopolysaccharide (LPS)-activated macrophages. Methods: LPS-activated mouse peritoneal macrophages were cultured in media with different concentrations of andrographolide. Cytotoxicity of andrographolide was detected by cell counting kit-8. The macrophages were lysed, and then expressions of phosphorylated ERK1/2, JNK and p38 and nuclear factor-κB inhibitor (IκBα) protein were detected by Western blotting and TNF-α mRNA expression was detected by reverse transcription-polymerase chain reaction. Supernatants of the macrophages were used to detect content of TNF-α protein by enzyme-linked immunosorbent assay. Results: Andrographolide at 1-100 μg/mL showed no cytotoxicity on LPS-activated mouse peritoneal macrophages. Andrographolide inhibited ERK1/2 phosphorylation in LPS-activated murine peritoneal macrophages, which was concentration-dependent (P<0.01). Andrographolide at 1-25 μg/mL had no effects on phosphorylation levels of JNK and p38 and IκBα degradation in LPS-stimulated mouse peritoneal macrophages. In activated macrophages, TNF-α expression was inhibited by 12 μg/mL andrographolide and 20 μmol/L PD98059 (inhibitor of ERK1/2 signaling pathway) at both mRNA expression and protein secretion levels. Conclusion: In LPS-activated macrophages, andrographolide may inhibit the expression of TNF-α by inhibiting ERK1/2 signaling pathway.

Objective:To explore the effect of Wnt/β-catenin signaling pathway on growth plate development of tibial growth plate in young chronic renal failure (CRF) rats.Methods:Four-week-old male SD rats were randomly divided into control group and CRF group ( n=20/per group). Control group was intragastric administration with distilled water, and CRF group was given adenine suspension (150 mg·kg -1·d -1). All the young rats were sacrificed after continuous gavages for 6 weeks. The full length of tibia was compared between the two groups. The width of tibia proximal growth plates was measured by micro-CT scanning, and the width of the growth plate was also measured in histological sections. Chondrocytes isolated from growth plate in two groups were cultured in vitro to P3 generation. Immunohistochemical staining was used to detect the expression of collagen Ⅱ, matrix metalloproteinase 13 (MMP-13) and β-catenin in chondrocytes. Western blotting was used to detect the protein expressions of collagen Ⅱ, MMP-13 and β-catenin. Results:Compared with the control group, the tibial length of rats in the CRF group was shorter [(27.32±5.81) mm vs (35.43±3.61) mm, t=5.226, P<0.001], the width of growth plate in micro-CT picture was more narrow [(0.72±0.22) mm vs (1.13±0.27) mm, t=5.096, P<0.001], and the relative width of the growth plate was also more narrow ( t=6.744, P<0.001) in histological sections. The results of immunohistochemistry and Western blotting showed the expressions of collagen Ⅱ in the CRF group decreased significantly ( t=8.212, P<0.001), MMP-13 ( t=13.091, P<0.001) and β-catenin ( t=7.534, P<0.001) increased significantly compared the control group in chondrocytes. Conclusion:The Wnt/β-catenin signaling pathway is highly expressed in the tibial growth plate of young rats with chronic renal failure, which leads to accelerated degeneration and differentiation of chondrocytes and a closure tendency of growth plate.

OBJECTIVETo correlate sperm nucleoprotein transition (SNT) with sperm morphology, DNA damage and embryo development, and assess its value for assisted reproductive technology (ART).

METHODSThe SNT of 437 infertile men underwent ART were assayed, and its correlation with sperm morphology, DNA damage, fertilization rate, normal fertilization rate, cleavage rate, available embryo rate, D3 high quality embryo rate, blastocyst formation rate and high quality blastocyst rate were analyzed.

RESULTSThe normal morphology rate of sperms, DNA damage, fertilization rate, normal fertilization rate, cleavage rate, embryo transfer rate (ETR), D3 high quality embryo rate, blastocyst formation rate (BFR) and high quality blastocyst in normal males (Group A, abnormal rate≤30%, 135 subjects) did not significantly differ from those with an abnormal rate between 30% and 60% (Group B, 170 subjects) (P>0.05). For those with an abnormal rate of above 60% (Group C, 132 subjects), the sperm normal morphology rate, DNA damage, normal fertilization rate, ETR, D3 high quality embryo rate, high quality blastocyst rate were significantly lower compared with Group A (P<0.01), while no significant difference was found in fertilization rate, cleavage rate and BFR between groups A and C (P>0.05).

CONCLUSIONSNT is related with sperm morphology rate, DNA damage and embryo development, and should be assessed before ART.

OBJECTIVETo explore the genetics mechanism for the phenotypic variability in a patient carrying a rare ring chromosome 9.

METHODSThe karyotype of the patient was analyzed with cytogenetics method. Presence of sex chromosome was confirmed with fluorescence in situ hybridization. The SRY gene was subjected to PCR amplification and direct sequencing. Potential deletion and duplication were detected with array-based comparative genomic hybridization (array-CGH).

RESULTSThe karyotype of the patient has comprised 6 types of cell lines containing a ring chromosome 9. The SRY gene sequence was normal. By array-CGH, the patient has carried a hemizygous deletion at 9p24.3-p23 (174 201-9 721 761) encompassing 30 genes from Online Mendelian Inheritance in Man.

CONCLUSIONThe phenotypic variability of the 9p deletion syndrome in conjunct with ring chromosome 9 may be attributable to multiple factors including loss of chromosomal material, insufficient dosage of genes, instability of ring chromosome, and pattern of inheritance.
