The effect of amygdalin joint hydroxysafflor yellow A (HSYA) on the endplate chondrocytes derived from intervertebral discs of rats induced by IL-1beta and the possible mechanism were studied and explored. Chondrocytes were obtained from endplate of one-month SD rat intervertebral discs and cultured primary endplate chondrocytes. After identification, they were divided into normal group, induced group, amygdalin group, HSYA group and combined group. CCK-8 kit was adopted to detect the proliferation of the endplate chondrocytes. FCM was measured to detect the apoptosis. Real-time PCR method was adopted to observe the mRNA expression of Aggrecan, Col 2 alpha1, Col 10 alpha1, MMP-13 and the inflammatory cytokines IL-1beta. The protein expression of Col II, Col X was tested through immunofluorescence. Compared with the normal group, the proliferation of the endplate chondrocytes decreased while the apoptosis increased (P < 0.05). With down regulation of the mRNA expressions of Aggrecan, Col 2 alpha1 and up regulation of the mRNA expressions of Col 10 alpha1, MMP-13, IL-1beta (P < 0.05), the protein expression of Col II decreased while the protein expression of Col X increased. Compared with the induced group, amygdalin group, HSYA group, the combined group could inhibit the apoptosis and promote the proliferation (P < 0.05). They could increase the mRNA expressions of Aggrecan and Col 2 alpha1 while decrease the mRNA expressions of Col 10 alpha1, MMP-13 and IL-1beta (P < 0.05). They could also enhance the protein expression of Col II while reduce the protein expression of Col X. The effect of the combined group was significantly better than that of amygdalin and HSYA. Amygdalin joint HSYA could inhibit the degeneration of the endplate chondrocytes derived from intervertebral discs of rats induced by IL-1beta and better than the single use of amygdalin or HSYA.

A capacitively coupled contactless conductivity detector for high performance liquid chromatography was developed. The detector was consisted of a signal generator, a signal amplifier, and a pair of tubular electrodes. A plastic connecting tube following the separation column was threaded through the two tubular electrodes. When the separated components passed the region between two tubular electrodes, they would be sensed. The instrumental parameters of this detector were investigated, including the internal diameter of connecting tube,the frequency and voltage of excitation signal, electrodes length, and the gap between two electrodes. The 0.5 mm of internal diameter of connecting tube, 70 kHz of excitation frequency, 60 V of excitation voltage,10 mm of electrodes length and 1.5 mm of gap between two electrodes were finally found to be the best working conditions for the detector. This HPLC-C4D(capacitively coupled contactless conductivity detector) was applied to the analysis of oleic and linoleic acids in Brucea javanica oil. The chromatographic peak area was linear with concentration for oleic and linoleic acids in 5-1000 μg/mL, and the limit of detection reached 2.5 μg/mL and 1.0 μg/mL,respectively. The results demonstrate that the present method is sensitive and accurate, proving this homemade contactless conductivity detector has a great application potential for pharmaceutical analysis in future development.

OBJECTIVETo discuss the perioperative management of hemophiliacs A with orthopaedic complications.

METHODSTo regulate the injection of factor VIII concentrate in peroperative period by testing the level of factor VIII:C in 27 cases. The lever of factor VIII:C was improved to 30% - 50% at the day before the operation. To the severe patients, it was maintained at 58.5% - 89.3% during the operation and at 47.0% - 78.4% in postoperation. While to the gentle, it was maintained at 38.5% - 52.5% during the operation and at 29.2% - 52.3% in postoperation. The individualized surgical procedures were carried out, such as arthrocentesis, open knee synovectomy or arthroscopic synovectomy, evacuation or curettage of haematoma, debridements, internal fixation.

RESULTSAll patients were cured in 14 - 105 days by regulating the injection of factor VIII during the peroperative period. The usage of factor VIII was 1 200 - 70 250 IU.

CONCLUSIONWhile the hemophiliacs have orthopaedic complications, it is necessary to promise the factor VIII:C being maintained at the lever of hemostasis during the peroperative period. The hemophiliacs are endurable to the operation.

The study was purposed to detect BAFF/APRIL gene expression changes in bone marrow mononuclear cells (BMMNC) and myeloma cell line U266 after interference with glucocorticoid and bortezomib. After separation of BMMNC from 7 patients with multiple myeloma, BAFF/APRIL mRNA expression in BMMNC and U266 cell line was detected by real-time PCR after treated with dexamethasone 100, 200 µg/ml, methylprednisolone 100, 200 µg/ml, bortezomib 0.1 µg/ml alone and dexamethasone or methylprednisolone combined with bortezomib respectively for 48 hours. The results showed that U266 cells and BMMNC of untreated MM patients highly expressed BAFF/APRIL genes. When dexamethasone, methylprednisolone or bortezomib was added to U266 cells or BMMNC alone, BAFF/APRIL gene expression decreased as compared with the blank control (p < 0.01). The inhibiting effect of bortezomib to BAFF/APRIL expression was obviously strong(p < 0.05). When dexamethasone or methylprednisolone combined with bortezomib, the BAFF/APRIL gene expression further decreased compared with dexamethasone or methylprednisolone alone (p < 0.01). As compared with the group of methylprednisolone combined with bortezomib, BAFF/APRIL gene expression decreased in dexamethasone combined with bortezomib with a statistically significant difference (p < 0.05). It is concluded that the expression of BAFF/APRIL gene is down-regulated after bing treated with glucocorticoids and bortezomib, which suggests that besides the glucocorticoid receptor and proteasomes targets, BAFF/APRIL and their receptor sites may be new targets of glucocorticoids and bortezomib.

3 mg/L was significantly worse than in those with hs-CRP≤3 mg/L (18.18%,5.45%;P=0.044,log-rank test). Higher hs-CRP concentration was an independent predictor of death or new vascular event(OR 3.609;95% CI 0.869—14.992;P=0.047).Conclusion Higher hs-CRP concentration in acute phase after ischemic stroke is an independent predictor of death or new vascular event in a year.

OBJECTIVETo evaluate the effect of vertebral height restoration of vertebroplasty for osteoporotic vertebra compression fractures (VCFs).

METHODSFrom October 2004 to June 2007, a total of 37 patients with 40 VCFs were treated by vertebroplasty. There were 12 males and 25 females with a mean age of (72.4 +/- 12.7) years (ranged, 48 to 87). Pain easement state was evaluated by visual analog scale (VAS) before and after operation, as well as in followed-up. Preoperative and postoperative vertebral height, kyphosis angle at fractured levels were measured on X-rays.

RESULTSAll of patients were followed-up for 12 to 47 months (averaged, 35.8 +/- 9.6). The VAS score was 8.4 +/- 1.6 before operative, 2.1 +/- 1.2 at the 2nd day after operative, there were significant difference between pre-and postoperative (P < 0.05); the average follow-up VAS was 1.6 +/- 0.9, there were significant difference as compared with the preoperative (P < 0.05). Lateral X-ray showed that the preoperative degree of vertebral height in the of anterior and middle vertebral were (72.0 +/- 10.6)% and (68.0 +/- 15.6)%, and postoperative were (76.0 +/- 8.6)% and (73.0 +/-6.1)%, respectively. There were no significant difference in vertebral height between preoperative and postoperative. The vertebral kyphosis angle was corrected from preoperative (7.8 +/- 2.7) degree to postoperative (8.1 +/- 2.3) degree.

CONCLUSIONVertebroplasty is a safe and effective method for treatment of osteoporotic VCFs, it can relieve the pain effectively. Failure to restore vertebaral height does not seem to interfere with the excellent pain management.

OBJECTIVE: To explore KM3 multiple myeloma (MM) cell line specific cytotoxic T lymphocyte (CTL) response in vitro mediated by autologous dendritic cells (DCs) aroused by KM3 cells' lysates and acid-eluted peptides. METHODS: Monocytes were isolated from the peripheral blood of healthy individuals and MM patients, and were cultured in serum medium with IL-4, GM-CSF, and TNF-alpha to generate DCs. These DCs were pulsed by KM3 cells' lysates or the acid-eluted peptides, then incubated with autologous T lymphocytes for 3 days to induce KM3 cell antigen specific CTL. MTT assay was performed to examine the specific KM3 cells' lysing ability of CTL. RESULTS: DCs were generated in peripheral blood monocytes cultured in the serum medium containing GM-CSF, IL-4, and TNF-alpha. Autologous T lymphocytes induced by IL-2 and DCs pulsed with KM3 cells' lysates or the acid-eluted peptides showed strong killing effect on KM3 cells. CONCLUSION The DCs pulsed by KM3 cells' lysates or the acid-eluted peptides incubated with autologous T lymphocytes can induce KM3 cell antigen specific CTL.
