Objective:To explore the role of γδ T cells in the transdifferentiation of immature dendritic cells(imDC) into osteoclasts(OC). Methods:(1) Peripheral blood mononuclear cells(PBMNC) were cultured with zoledronate(Zol) and recombinant human interleukin-2(IL-2),and PBMNC from healthy volunteers were cultured with granulocyte macrophage colony-stimulating factor (GM-CSF) and recombinant human interleukin-4(IL-4) to differentiate into imDC,which were then cultured with receptor activator nuclear factor к B ligand(RANKL) and macrophage colony-stimulating factor(M-CSF) to differentiate into OC. The purity of γδ T cells,and phenotype changing of OC transdifferentiated from imDC were investigated by flow cytometry. (2) Co-culture system was es-tablished using millicell inserts.γδT cells isolated with immune magnetic bead were placed in the upper compartment and imDC in the lower compartment in the ratio of 10∶1. To explore the role of γδ T cells during differentiation of imDC into OC,tartrate resistant acid phosphatase( TRAP) staining and bone resorption observation staining were used. Tumor necrosis factor-alpha( TNF-α) of supernatant liquid from different cultures was measured using ELISA(Enzyme linked immunosorbent assay) kit. Results:(1) γδT cells can be ex-panded from PBMNC of MM patients, and the production capacity was similar to that of healthy volunteers ( 68. 87%± 20. 94% vs 69. 33%±16. 84%,P>0. 05 ) . ( 2 ) OC could be transdifferentiated from imDC when cultured with RANKL and M-CSF. ( 3 ) The number of TRAP+ multinuclear cell and the absorption area of dentine were significantly lower in the group of imDC indirectly co-cultured with γδ T cells than in the group of control imDC(5.67±0.58 vs 28.33±2.08,4.97%±4.3% vs 28.47%±12.8%, respectively). (4) Under the circumstance of γδ T cell-imDC indirect coculture,TNF-α got significantly higher. Conclusion: γδ T cells might inhibit the transdifferentiation of imDC into OC.γδ T cells-based immunotherapy is expected to be a new treatment for myeloma bone disease.

BACKGROUND: Essential tremor is a kind of dyskinesia disease with a tendency to heredity. β-adnephrin receptor blocker is mainly used for treatment, but the dosage was great, patients could not persist in treatment. Hydrochloric-acid arotinolol, which characterizes by little side effect, is a β-receptor blocking agent combined with blocking effect of α receptor, and is an ideal drug to treat essential tremor in Japan.OBJECTIVE: To observe the reliability and curative effect of hydrochloric-acid arotinolol on essential tremor among Chinese people.DESIGN: Case analysis.SETTING: Neurological Departments of Beijing Hospital of Ministry of Public Health and General Hospital of Beijing Military Area Command of Chinese PLA.PARTICIPANTS: Totally 30 patients with essential tremor, 19 males and 11 females, aged from 21 to 74 years, with course of 1-40 years, average of (15.8±12.6) years, were selected from Neurological Departments of Beijing Hospital of Ministry of Public Health and General Hospital of Beijing Military Area Command of Chinese PLA from April 1999 to December 2000.METHODS: Tremor degree of upper limb, caput and lower limb, degree of dysfunction of hand, tremor degree of hand during writing and circling, and chief complaint of pain caused by tremor were scored before medication and 2, 4 and 6 weeks after medication. Scores were determined as 1 point, 2 points and 3 points according to mild, moderate and severe degree respectively. Evaluated criteria: ① Obviously effective: Differences were more than 7 points before and after treatment. ② Effective: Differences were 6.5-3 points before and after treatment. ③ A little effective: Differences were 3-1.5 points before and after treatment. ④ No changes: Differences were from 1 to -1 points before and after treatment. ⑤ Worse: Differences were less than -1.5 points before and after treatment. Meanwhile, blood pressure and heart rate of patients and side effect of drug were observed.MAIN OUTCOME MEASURES: ① Results of effective evaluation; ②Blood pressure and heart rate before and after treatment; ③ Adverse events and side effect.RESULTS: Totally 30 patients entered the final analysis. ① Among 30 patients with essential tremor, 6 had obvious effect, 11 had effect, 5 had a little effect, 7 had no effect, and 1 was worse. ② Average of blood pressure before treatment was (138.5±14.6)/(84.2±6.4) mm Hg (1 mm Hg=0.133 kPa), and was (130±10)/(79.7±6.3) mm Hg after 1 course. Average heart rate was (77.5±6.4) times/minute before treatment and (75±6.4) times/minute after treatment. The difference was not significant. ③ Among 30 patients, 4 had side effect at various degrees which was accounted for 13.4%; 1 had distress after medication, 1 had agrypnia, 2 had fullness in head and dizziness, and 1 gave up the treatment because of deteriorated tremor.CONCLUSION: Hydrochloric-acid arotinolol can improve tremor symptom of patients obviously and is an effective drug to treat essential tremor with convenient and safe medication.

To study the expression of beta-human chorionic gonadotropin (beta hCG) genes in renal cell carcinomas (RCC) and benign renal disease tissues, nested reverse transcription-polymerase chain reaction (RT-PCR) and restriction endonuclease analysis were employed to detect the expression of beta hCG genes in 44 cases of RCC tissues and 24 cases of benign renal disease tissues. It was found that 52% RCC samples revealed positive for beta hCG mRNA expression. Positive rate in advanced stage and poorly differentiated RCC was higher, but there was no significant difference. The positive rate of beta hCG mRNA expression was 54% in 24 cases of benign renal tissues, including 3 cases out of 6 polycystic kidneys, 7 cases out of 13 renal atrophies, 2 cases out of 2 oncocytomas and 1 case out of 2 pyonephrotic kidneys. beta 7 was most frequently transcribed subtype gene independent on the histology. These findings suggested beta hCG gene transcription is not only involved in RCC but also in benign renal diseases.

Aim The aim of this study is to determine effect of ST2325 on HER2/neu tyrosine kinase signal pathway and cell cycle in breast cancer BT474 cells. Methods Protein expression was detected with immunoblot analysis. Cell cycle distribution was examined using flow cytometry.Results ST2325 inhibited tyrosine phosphorylation of HER-2/neu in a dose-dependent manner with half maximal inhibition occurring at a concentration of 8.7 ?mol?L -1 without reduced HER-2/neu receptor protein expression. Activation of MAPK and AKT, downstream molecules of HER-2/neu-mediated signal transduction pathway was inhibited following exposure to ST2325. After BT474 cells were treated with different concentrations of ST2325 for 24 h, the results of flow cytometry analysis showed cell cycle arrest in G 1 phase. Western blot assay showed up-regulation of p27 protein expression and decrease of hyperphosphorylated Rb and cyclin D1 protein expression.Conclusions ST2325 inhibits HER2 tyrosine kinase phosphorylation and induces G 1 arrest in BT474 cells. Cell cycle arrest in G 1 is associated with p27 up-regulation, decrease of cyclin D1 protein and hyperphosphorylated Rb.
