Objective To observe the effects of berberine hydrochloride on the secretion of interleukin-6(IL-6)from human periodontal ligament cells(PDLCs)cultured in vitro.Methods Periodontal ligament tissues were isolated from extracted human premolars,and PDLCs were cultured in vitro.After identification by immunohistochemistry technique,human PDLCs were divided into LPS group and NLPS group according to whether lipopolysaccharide(LPS,50 ?g/mL)was contained in cell culture media.Then in accordance with the final concentrations of berberine hydrochloride in cell culture media(0,0.010,0.020,and 0.030 g/L),the groups were subdivided into LPS and NLPS control group,LPS1 and NLPS1 group,LPS2 and NLPS2 group,LPS3 and NLPS3 group.IL-6 contents in supernatants of each group were determined by enzyme-linked immunosorbent assay,and statistical analysis and comparison were conducted as well.Results Compared with corresponding LPS and NLPS groups,IL-6 contents in supernatants of LPS3 group and NLPS3 group reduced markedly(P

Objective:To observe the difference of the therapeutic effect between heat-sensitive moxibustion and warm needling therapy for cervical spondylosis of vertebral artery type (CSA).
Methods:A total of 60 cases with CSA who met the inclusion criteria were randomly divided into a heat-sensitive moxibustion (HSM) group and a warm needling therapy (WNT) group according to the visiting sequences, with 30 cases in each group. Patients in the former group were treated by heat-sensitive moxibustion, while patients in the latter group were treated by warm needling therapy. Both groups were treated once every other day, with 10 times as 1 course of treatment, and the therapeutic effects were evaluated after 1 course of treatment.
Results:After 1 course of treatment, the total effective rate of the HSM group was 93.3%, versus 83.3% in the WNT group. There was a statistically significant difference between the two groups (P<0.05).
Conclusion:Heat-sensitive moxibustion has better therapeutic effect for CSA than warm needling therapy.

Fanconi anemia (FA) is an rare autosomal recessive inherited disease which manifests progressive marrow failure, congenital bone malformation, high risk to cancers and so on. Chromatin of FA cells display auto-instability and high hypersensitivity to interstrand DNA cross-links such as mitomycin C. As normally FA develop into acute myeloid leukemia easily, it has been regarded as pre-leukemia state. Till now 11 FA genes have been found and play a role in sustaining stability of gene groups through the same mechanism. As an active connecting protein, FANCF protein play an important part in correct FA complex formation. Which makes FANCD2 single ubiquitin. Ubiquitin FANCD2 induces chromatin and BRCA1 interact, and repair injured DNA. FA gene defect makes gene group instable and increases the risk of chromatin collapse, which finally leads to acute myeloid leukemia and myelodysplastic syndrome.

AIM: The aim of this investigation was to confirm the best operation conditions in the membrane separation of protein from the homogenate of red earthworm, Eisenia faefida. METHODS: Ultrafiltration membrane of fresh red earthworm with the cut-off of 10 000 was used as the target process, with the homogenate flux as index, the best value of operation parameters such as pressure、 temperature, surface rotation speed and feed concentration were fixed on. RESULTS: (1) The best suitable operation conditions were 0.25 MPa, 30?C , 200 r/min, pH=6.7, 33.3% (w:w) concentration and not a bit of NaCl. (2) The molecular weight distribution of protein in the homogenate of red earthworm mainly lay between 50 000~100 000. CONCLUSION: The obtained experimental results will provide pilot scale test with data support.

Objective To explore the mechanism of lower molecular weight heparin(LMWH) in the treatment of severe acute pancreatitis(SAP). Methods Wistar rats were randomly divided into 3 groups: Sham group(S group),severe acute pancreatitis group(SAP group) and LMWH treatment group(H group). The serum amylase,IL-6,expressions of p65 mRNA and the activity of NF-?B were tested. Results The value of amylase and IL-6 in SAP group was significantly higher than that in H group (P

Epidermal growth factor receptor (EGFR) is found to express at high levels in a variety of solid tumors including gliomas. This study was to examine the effect of an EGFR-tyrosine kinase inhibitor (AG1478) alone or in combination with cisplatin (CDDP) on the growth of glioma cells (U87). U87 glioma cells were treated with AG1478 (10 μmol/L) or CDDP (25 μmol/L) as a single agent or in combination for 24 or 48 h. The expression of EGFR and the components in its downstream signaling pathway [extracellular signal-regulated kinase (ERK), protein kinase B (AKT)] in U87 glioma cells was detected by Western blotting. Cell growth, cell cycle distribution and cell apoptosis were determined by MTT method and flow cytometry, respectively. The results showed that CDDP could induce the activation of EGFR and the components in its downstream signaling pathways in a concentration-dependent manner. The combined treatment of AG1478 with CDDP could inhibit the proliferation of U87 glioma cells, arrest the cell cycle and promote cell apoptosis. In the EGFR signaling pathway, AG1478 decreased the phosphorylation of ERK, AKT and EGFR in U87 glioma cells. It was concluded that the combined treatment of AG1478 and CDDP may exert synergistic inhibitory effects on the growth of glioma cells by suppressing the activities of EGFR, AKT and ERK.

Objective To modify the techniques for establishment of an abdominal working heart transplantation model in rats and to sum up the key factors to success.Methods A total of 180 12-week old Brown Norway rats ( donor) and Lewis rats ( recipient) were used in this study:50 BN rats and 50 Lewis rats for pilot experiment, and 40 BN rats and 50 Lewis rats for the formal experiment.The rat model of working heart heterotopic transplantation was adopted and estab-lished by Wiedemann’ s mode.We transplanted the heart from BN rats to Lewis rats and analyzed the survival rate, causes of death and histological changes of the heart ( HE staining) in this experiment.Results After exercise and modification, the survival rate was increased to 77.5%, and the mean total duration of operation was 71 ±11 min, and the mean ische-mic time of the donor hearts was 34 ±5 min.Histological examination ( HE staining) of the cardiac allograft showed a mild inflammatory cell infiltration in the graft at 24 h after transplantation, indicating that the model was reliable.Conclusions A variety of factors may affect the final operation success rate in the establishment of this heart transplantation model.A-mong them, the major affecting factors include: healthy animals, donor heart protection, rapid and effective vascular su-ture, and postoperative animal management.
