Objective To investigate the effects of cadmium on bone loss in ovariectomized rats. Methods Female Sprague-Dawley rats, aged 6 months, were divided to 5 groups, i.e. sham operation group (sh) , control group (ovariectomy 0 mg/L Cd), low dose group (ovariectomy+50 mg/L Cd), medium dose group (ovariectomy+100 mg/L Cd), high dose group (ovariectomy+200 mg/L Cd). Cadmium was administrated via drinking water. After 24- week exposure, the following indices were measured, bone mineral density (BMD) at the femurs necks, serum estradiol, urinary and blood cadmium, urinary ? 2-MG, bone calcium and cadmium, and calcium contents in feces and urine. Results Estradiol and BMD significantly declined in the ovariectomized rats. Cadmium administration aggravated the declines of BMD in a dose-effect pattern. Urinary ? 2-MG, the excretions of calcium in feces and urine were significantly higher in cadmium-exposed groups in a dose-effects pattern. And bone calcium was also significantly lower in the group exposed to 200 mg/L cadmium than in the control group. Conclusion It is indicated that cadmium could increase bone loss and decrease BMD in ovariectomized rats by increasing the excretions of calcium in feces and urine.

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.

While the medicine pattern of biomedicine turn to biological-psychology-society, the medical trouble communication becomes more and more important in the medical service. Good medical trouble communication ability is the essential condition of doctor. As oral cavity clinicians, only by gasping the principle of communication can we appropriately utilize some skills of communication exchange,establish the good medical trouble relations with the patient and achieve the good treatment result finally.

There are many progresses in the therapy of MM with ASCT. ASCT improves the ratio of CR,EFS and OS,compared with conventional chemotherapy.Myeloma patients with renal failure or old age also can be candidate for ASCT.Tandem autologous transplantation improves the ratio of CR. Its impact to long-term EFS and OS still need to be judged.To improve conditional project,to choose suitable time,and- toselect consolidation schedule can boost therapeutic effect.

Professional postgraduates in geriatric medicine are one of the most important re-courses of geriatric specialists. However, training model for geriatric postgraduates is still unclear in China. In general, geriatric medicine has no independent training plan, and is included in internal medicine training. Such model cannot represent the feature of geriatric medicine. The present paper aimed to discuss the ability construction for geriatric postgraduates based on the geriatric medicine specialist training experience both at home and abroad, including diagnosis and treatment of multi-system diseases, ability of geriatric assessment, management of geriatric syndromes, consultation for geriatric rehabilitation and ability for continuity health service in order to cultivate the compound tal-ents suitable for the aging society requirement for geriatric medicine in China.

Objective The study aimed to compare the vector system with the hand instrument in the pain severity during scaling and root planning.Methods 60 periodontal patients were randomly divided into two groups for supportive periodontal therapy (SPT):the experimental group (using vector system) and the control group (using gracey instruments),with 30 cases in each group.And the painfulness after SPT was evaluated by Visual Analogue Scale (VAS).Results 66% patients felt mild pain during the supportive periodontal therapy with the application of vector system,while 36% patients felt mild pain in the control group.24 patients in the experimental group accepted vector system for SPT and 23 patients in the experimental group felt less fear of the treatment.Conclusions Patients will feel less discomfort with the application of the vector system,therefore better compliance will be reached.And the cooperation of the doctors and nurses has great impact on the treatment effect.

Objective To improve the establishment of rabbit model with VX2 liver tumor and assess sonographical value in monitoring the tumor growth.Methods Fifteen New Zealand white rabbits were implanted with VX2 tumor in two liver lobes under ultrasound guidance percutaneously.Ultrasound examinations were performed at twenty days and thirty-six days after implantation.At the same time exploratory laparotomy was performed.Results Among 30 implanted tumors of 15 rabbits,16(53%) tumors were successfully implanted with few complications.It took 15 to 40 minutes to implant tumors in one rabbit.Implantation rates of left lobe and right lobe were 53% and 50% respectively,and there was no significant difference.Ultrasound examination could monitor tumor growth well.Conclusions After the improvement,the establishment of model was easier,less time-consuming,minimally invasive and caused few complications than other implantation methods.Serial ultrasound examinations should be performed in monitoring the tumor growth.
