Tumor 2008;28(11):964-967
Objective: To observe the effect of bortezomib (Btzmb) on the differentiation and function of osteoclasts from patients with multiple myeloma (MM) during their maturation in vitro and investigate the influence of Btzmb on the expression of tumor necrosis factor receptor-associated factor (TRAF6), one of the key signaling molecules on the upstream of osteoclasts differentiation. Methods: Osteoclast precursor mononuclear cells were isolated from peripheral blood of MM patients and cultured with receptor activator of NF-κB ligand (RANKL) and macrophage colony stimulating factor (M-CSF) and different concentrations of Btzmb. The number of tartrateresistan acid phosphatase (TRAP)-positive osteoclasts was counted. The TRAP activity in the supernatant was tested. The extent of the ivory slice resorption was observed. The effects of Btzmb on the mRNA and protein expressions of TRAF6 were determined by RT-PCR and Western blotting, respectively. Results: After Btzmb 2.5 and 5 nmol/L treatment, the number of osteoclasts were reduced compared with the control group [(157 ±21) and (98 ± 15) vs (307 ± 25), P < 0.05]. The number of the ivory slice resorption decreased [(53 ± 24)% and(29 ± 7)% of the control, P < 0.05]. The TRAP activity in the supernatant was inhibited [(86 ± 24)% and(60 ± 25)% of the control, P < 0.05]. The activity of TRAF6 protein gradually declined and the levels of TRAF6 mRNA also decreased at 24 h after Btzmb treatment. Conclusion: Btzmb can inhibite the differentiation and function of osteoclasts. The action of Btzmb may be related with TRAF6.

Objective To compare the effects of every-other-day dose simvastatin administration with that of daily therapy of same dose.Methods This was a randomized,prospective,nonblinded clinical trial.The 186 patients with high low-density lipoproteim cholesterol(LDL-C) and/or high total cholesterol (TC),triglycerides (TG),low high-density lipoprotein cholesterol(HDL-C)was studied.All patients were randomized into two groups.The every-other-day do- sing group recerived 20mg of simvastatin in alternate-day and daily dosing group received 20mg of simvastatin every day.Before and after 6 weeks,12 weeks of treatment,serum lipoprotein,Live function tests and ereatine kinase con centra- tion and so on were drawn and bad-side effect were studies.Results The two groups significantly reduce LDL-C,TC, TG and a little increased HDL-C compared with baseline.No stalistically significant differences existed between the two groups in percentage in decrease in lipoprotain at 6 weeks,12 weeks compared with baseline.The bad-side effect in the two groups also had not a singnificant different.Conclusion The every-other-day dose of simvastatin have similar effi- cacious and safe to daily dosing in patients with hyperlipidemia and some cost savings.It can take a primary prevention to coronary heart disease in patients with relatively low-risk hyperlipidemia.

Objective To explore the value of brainstem auditory evoked potential(BAEP),visual evoked potential(VEP)and Revised Visual Retention Test(VRT)in detecting impairment of central nervous system in patients with acute leukemia(AL).Methods Neuropack-Ml type evoked potential machine(Japan)was used to check brainstem auditory evoked potential(BAEP)and visual evoked potential(VEP).BAEP,VEP and VRT were examined in 30 cases with acute leukemia(group AL)and in 30 age and sex matched healthy subjects as a control(groupC).Indexes of BAEP including peak latency(PL)of waves I ,IB ,V and inter-peak latency(IPL)of waves Ⅰ~Ⅲ,Ⅲ ~Ⅴ,Ⅰ~Ⅴand indexes of VEP(P100PL)were determined.VRT was accomplished meanwhile applying B method with C pattern,C method with D pattern,D method with E pattern.The correct scores and error scores were recorded separately.Results BAEP:the abnormal rate of the group AL was 23.3 %.Compared with control group,we found significant longer latency of wave Ⅲ、Ⅴ(P<0.05)and significant elongation in the mean inter-peak latencies of Ⅰ~Ⅴ(P<0.05).VEP:the abnormal rate of the group AL was 26.7% ,the P100 PL of the patients was longer than that in the control group(P<0.05).VRT:the abnormal rate of the group AL was 33.3%.The results of VRT showed that the score in the group AL in D method with E pattern was lower than that in the control group(P<0.05).Conclusion BEAP,VEP and VRT could detect the impairment of central nervous system in patients with acute leukemia sensitively,and give clues to early diagnosis of central nervous system leukemia(CNSL).

Objective To investigate the status and requirement of knowledge of reproduction and acquired immunodeficiency syndrome (AIDS)/sexually transmited disease (STD) in pregnant adolescents with abortion in order to conduct proper interventions. Methods Two hundred and ninety-one unmarried pregnant adolescents below 22 years old with abortion completed questionnaires which involved the information on individual social-demographics characteristics, knowledge of reproduction, AIDS/STD and sex-related beliefs, attitudes and partners. Results Among these 291 adolescents, 37.7% experienced first sexual intercourse before 19 years old, 69.1% performed well in the knowledge of reproduction, and 62.6% and 43.5% did well in the knowledge of AIDS and the knowledge of the other STD, respectively. The rate of implementation of contraception was far less than that of awarenesss of contraception(P<0.05). These pregnant adolescents were not enthusiastic for seeking reproductive knowledge, and 45.0% would like to acquire the knowledge from professionals. Conclusion The knowledge of reproduction and AIDS/STD in the pregnant adolescents is not adequate, and they fail to carry out the proper behaviors of contraception. More education should be conducted on AIDS/STD prevention and contraception among pregnant adolescents.

Objective To evaluate the safety and effectiveness of vitrectomy combined with internal limiting membrane (ILM) tamping on macular hole and retinal detachment (MHRD) in highly myopic eyes.Methods 23 patients (23 eyes) were retrospectively reviewed,who were diagnosed as MHRD through examination of the ocular ftmdus,optic coherence tomography (OCT) and B-mode ultrasonography.There were 5 males (5 eyes) and 18 females (18 eyes).The mean age was (62.35 ± 8.28) years.The mean course of disease was 1.1 months.The logarithm of the minimum angle of resolution (logMAR) best-corrected visual acuity (BCVA) was 2.31 ± 0.72.The mean axial length was (28.66 ± 1.99) mm.All patients underwent 23G microincision vitrectomy.After vitreous gel and cortex were gently resected,the ILM around the edges of the macular hole was stained with indocyanine green,and was folded and pushed to fill the macular hole gently.Then silicone oil or C3F8 gas tamponade was applied in 18 eyes and 5 eyes,respectively.The silicone oil was removed after 3 months.The follow-up was 6 months.The BCVA,macular hole closure,retinal anatomical reattachment were retrospectively observed,and were used to evaluate the safety and effectiveness of the surgery.Results At the 6 months after surgery,the logMAR BCVA was improved to 1.13 ± 0.38,the difference was significant (t=l 5.33,P=0.00).The postoperative macular hole closure rate and retinal anatomical reattachment rate were 100%.There were no ocular or systemic adverse events observed in all patients.Conclusion Vitrectomy combined with ILM tamping is an effective and safe treatment for the high myopic eyes with MHRD.
