OBJECTIVEThis study aimed to explore the effect of the up-regulation of Notch1 on osteoclastogenesis induced to osteoclasts by receptor activator for nuclear factor-kappaB ligand (RANKL) and macrophage colony-stimulating factors (MCSF) in vitro.

METHODSThe bone marrow stem cells (BMSCs) of Rosa(-notch1) mice were cultured and induced to osteoclasts by RANKL and MCSF. The BMSCs were transfected with the Ad-Cre-green fluorescent protein (GFP) virus or Ad-GFP virus. Total RNA from cells was extracted, and the gene expression levels of Notch1, Notch2, Notch3, Notch4, Deltal, Delta3, Delta4, Jagged1, Hes1, and tartrate resistant acid phosphatase (TRAP) were detected at the defined stage by reverse transcription-polymerase chain reaction (RT-PCR). Osteoclast formation was analyzed by TRAP assay.

RESULTSThe number of TRAP-positive multinuclear cells of the experimental group significantly decreased compared with that of the control group. The mRNA expression levels of Notch1, Notch3, Jagged1, Delta3, and Hesl of the experimental group were significantly higher than those of the control group, whereas the TRAP mRNA expression of the experimental group was significantly lower than that of the control group (P<0.05).

CONCLUSIONUp-regulation of Notch1 inhibit osteoclastogenesis of BMSCs induced by RANKL and MCSF in vitro.

OBJECTIVETo evaluate the effect of the oral-appliance in the treatment of ED induced by obstructive sleep apnea-hypopnea syndrome (OSAHS).

METHODSThis study included 40 cases of OSAHS-induced ED. Based on the apnea-hyponea index (AHI) and lowest SaO2, we divided the patients into groups A (AHI < or = 30/h and lowest SaO2 > or = 80%) and B (AHI > 30/h and lowest SaO2 < 80%), and treated them with the oral-appliance for 3 months, followed by evaluation of the therapeutic effect using polysomnography, IIEF-5 questionnaire and Sexual Encounter Profile (SEP) diaries.

RESULTSThirty-seven of the patients accomplished the treatment, 16 in group A and 21 in group B. Compared with the baseline, the AHI was significantly decreased in both groups A (21.4 +/- 7.3 vs 14.2 +/- 6.6, P < 0.05) and B (51.4 +/- 9.5 vs 29.7 +/- 8.1, P < 0.05) after treatment, the IIEF-5 scores increased, even more remarkably in B than in A (3.36 +/- 2.48 vs 1.12 +/- 1.27, P < 0.05). The positive rates of SEP2 and SEP3 were markedly lower in A than in B (37.5% vs 76.2% and 25.0% vs 61.9%, P < 0.05).

CONCLUSIONThe oral-appliance can improve the erectile function of OSAHS-induced ED patients, particularly for those with severe OSAHS.

Objective To investigate the level change of interleukin-4(IL-4) and IL-12, and their effect on airway inflammation in rat asthma. Methods Rat model of asthma was set up by ovalbumin sensitization. Total cell count and eosinophil count in branchoalveolar lavage fluid(BALF) were performed, and levels of IL-4 and IL-12 in BALF were measured by ELISA. Results After ovalbumin sensitization, airway occurred obvious inflammation. Eosinophil count began increasing at 1 hour after sensitization, obviously increased at 8 hours, reached a maximum at 24 hours, started declining at 96 hours, and decreased to near normal range at 7 to 14 days. The changes of total cell count had the same tendency as eosinophil count changes. The level of IL-4 in BALF elevated at 1h after sensitization, reached a maximun at 8 to 96 hours, and reduced to near normal level at 7 to 14 days. The changes of IL-12 in BALF had the same tendency as IL-4 level changes. Eosinophil count was positively related with IL-4 level(r=0.74,P0.05). There was a close correlation between IL-4/IL-12 ratio and eosinophil count (r=0.85,P

Objective To investigate the feasibility and efficacy of combined preoperative chemora- diation program followed by radical surgery in bulky early or moderate uterine cervical cancer.To determine the incidence and predictive value of rasidual disease in the radical hysterectomy specimens after CCR. Methods Thirty-five patients with uterine cervix carcinoma from January 2001 to September 2003 were treated with preoperative external beam radiotherapy to 3060 cGy in 4 weeks.Patients received concurrent continuous infusion cisplatin(20 mg/m~2)on day 1,8,15,22 of four weeks and 5-Fu(4 g)chemotherapy during the first four days and the last four days of the radiation course.Radical surgery was not performed until 4 weeks after the completion of the preoperative treatment.Results Clinical response was 85.71%,complete response,54.29 %;partial response,31.43 %.The analysis of the surgical specimens showed 19 patients had revealed residual disease and 16 patients had revealed no residual disease,the complete pathological response hed been 45.71%.Three-year survival rate was 87.14 % in 35 patients.Three-year survival rate of residual disease patients(76.32 %)was significantly lower than that of no residual disease(100.0 %)(P=0.0358). Three-year survival of cervical stromal invasion less than 1/2 and invasion extra stromal was 100.0 %, 41.67 % respectively(P=0.0109);three-year survival of lymph-vascular space involvement and no lymph- vascula space involvement was 0,85.29 %,respectively(P=0.0148).Conclusion Combined preoperative chemoradiation program followed by radical surgery in bulky early or moderate cervical cancer could reveal an effective efficacy with a tolerant complication.Residual disease is an independent and strong predictive factor.

As a member of tyrosine kinases(TK) family,Epidermal growth factor receptor(EGFR) has an activity of intrinsic protein tyrosine kinase,which plays an essential role in the regulation of signal transduction in the cells.Due to the abnormal expression of EGFR-TK,the certain type cancers may developed and progressed.Based on that,the inhibitors of EGFR-TK could be effective medicines for the treatment of cancer.The EGFR-TK domain was amplified by RT-PCR with RNA of HUVCEs cells as the template and expressed in E.coliBL21(DE3) using plasmid pET30a as vector.The recombinant protein was purified with the affinity chromatography(Ni-NTA),which was identified to have kinase activity catalyzing the substrate phosphorylated with ATP in the enzymatic reaction.Using the recombinant EGFR-TK as target,the screening model for enzymatic inhibitors was constructed.
