[Conclusions]There are a lot of compatibility knowledge in classical prescriptions. Comprehending and grasping the compatibility characters and the clinical applications of the Angle Medicinesof Aconiteare is very unique and ingenious for modern clinic.

ObjectiveTo explore the effects of heat treatment and ultraviolet B (UVB) radiation alone or in combination on the expression of heat shock protein (HSP) 72 in human epidermal melanocytes.Methods Melanocytes were obtained from human foreskin,and subjected to primary culture.After 3 to 5 passages,the melanocytes were classified into 4 groups:control group (receiving no treatment),heat treatment group (treated with heat at 42 ℃ for 1 hour every day for 3 days),UVB group(irradiated with UVB at 50 mJ/cm2 daily for 3days),combination group(treated with heat at 42 ℃ for 1 hour followed by irradiation with UVB at 50 mJ/cm2daily for 3 days).After another 2- to 6-hour culture following the last treatment,melanocytes were collected and subjected to real time PCR and Western blot for the detection of HSP72 mRNA and protein expression,respectively.ResultsThe mRNA and protein expressions of HSP72 were significantly higher in the heat treatment group and combination group than in the control group (mRNA:6.584 ± 0.871 and 7.269 ± 0.454 vs.0.975 ± 0.089,both P ＜ 0.001; protein:2.022 ± 0.058 and 2.080 ± 0.045 vs.0.532 ± 0.033,both P ＜ 0.001 ),but was similar between the UVB group and control group (mRNA:0.832 ± 0.084 vs.0.975 ± 0.089,P ＞ 0.05;protein:0.546±0.021 vs.0.532 ± 0.033,P ＞ 0.05).The ANOVA of factorial design showed that neither heat treatment nor UVB irradiation had interaction effect on the mRNA or protein expression of HSP72 (F =2.106,1.399 respectively,both P ＜ 0.05).ConclusionsHeat treatment can cause an increase in the expression of HSP72,which may enhance the function of melanocytes and protect melanocytes from UVB induced damage.

ObjectiveTo investigate the effect of heat treatment combined with narrow band ultraviolet B(NB-UVB) on cultured normal human melanocytes in vitro.MethodsMelanocytes were isolated from the foreskin of normal human,cullured in vitro,and irradiated with NB-UVB of different doses(20,30,50,70,90,120 and 180 mJ/cm2).Then,MTT assay was performed to evaluate the proliferation and activity of melanocytes to determine the optimal dose of UVB for the next experiment.Melanocytes were classified into 3 groups to be treated with heat at 42 ℃ for 1 hour (heat group),irradiated with UVB at 50 mJ/cm2 (UVB group),or irradiated with UVB at 50 mJ/cm2 followed by heat treatment at 42 ℃ for 1 hour (combination group),daily for 3 successive days; those receiving no treatment served as the control.After 24-hour culture following the last treatment,tyrosinase activity was evaluated with L-dopa as the substrate,melanin content was detected by NaOH assay,and cell cycle stages were determined by flow cytometry.ResultsNB-UVB irradiation decreased the viability of melanocytes in a dose-dependent manner,and the optimum dose of UVB was 50 mJ/cm2.The tyrosinase activity of melanocytes was 0.244 ± 0.018 and 0.310 ± 0.015 respectively in the UVB group and combination group,and increased by 3.8％ (P ＜ 0.05) and 31.9％ (P ＜ 0.05) respectively compared with the control group (0.235 ± 0.018); the melanin content was 0.201 ± 0.016 and 0.286 ± 0.019,respectively in the UVB group and combination group,and increased by 17.5％ (P ＜ 0.05 ) and 67.3％ (P ＜ 0.05) compared with the control group (0.171 ± 0.016).In comparison with the control group,the percentage of melanocytes in G1 phase was decreased by 23.94％ in the UVB group(P＜ 0.05) and 33.51％ in the combination group(P ＜ 0.05),while that in S phase and G2 phase increased by 15.35％ (P ＜ 0.05 ) and 11.93％ (P ＜ 0.05),respectively in the UVB group,and 17.76％ (P ＞ 0.05) and 16.08％ (P ＞ 0.05),respectively in the heat group.ConclusionHeat treatment and NB-UVB can synergistically enhance the tyrosinase activity and accelerate melanogenesis,proliferation and differentiation,of melanocytes.

OBJECTIVEThis study aimed to improve students' ability in practical and theoretical courses of oral health education and to promote students' learning interest and initiative.

METHODSFourth-year students of the oral medical profession from 2006 to 2008 at Weifang Medical University were chosen as research objects for oral health education to explore the experimental teaching reform. The students were divided into test and control groups, with the test group using the "speak out" way of teaching and the control group using the traditional teaching method. Results of after-class evaluation of the test group, as well as final examination and practice examination of the two groups, were analyzed and compared.

RESULTSAfter-class evaluation results of the test group showed that the "speak out" teaching method was recognized by the students and improved students' ability to understand oral health education. The final examination and practice examination results showed that the score of the test group was higher than that of the control group (P < 0.01).

CONCLUSION"Speak out" teaching methods can improve students' ability for oral health education, in accordance with the trend of teaching reform.

BACKGROUND:Fetal bovine serum based media used for expanding and cryopreserving human mesenchymal stem cells raise safety concerns in the clinical setting. OBJECTIVE:To investigate the feasibility of human umbilical cord blood plasma as a replacement for fetal bovine serum in culture and cryopreservation of human mesenchymal stem cells derived from umbilical cord. METHODS:Umbilical cord blood units were suitable for this research if they fulfil ed the donor selection criteria of the Guangzhou Cord Blood Bank strictly. Cord blood plasma was ready to use after col ected from the plasma reduction during the suitable cord blood units processing and pooling. Umbilical cord mesenchymal stem cells were harvested from the umbilical cord tissue of health ful-term newborns after delivery by enzyme digestion and were cultured in the presence of Dulbecco’s modified Eagle’s medium/Ham’s nutrient mixture F-12 containing either fetal bovine serum or pooled cord blood plasma. Morphology, proliferation, immunophenotype detected by flow cytometry and differentiation toward adipogenic and osteogenic lineages were utilized for investigating the effect of media on umbilical cord mesenchymal stem cells after 3-5 passages. Then cells were cryopreserved in media containing 10%dimethyl sulfoxide, 20%fetal bovine serum or 20%pooled cord blood plasma for at least 6 months. Viability, adhesion, proliferation, immunophenotype and osteogenic differentiation of the cells were assessed after thawing. RESULTS AND CONCLUSION:The morphology (spindle-shaped and plastic-adherent), phenotype and differentiation potential (osteogenic and adipogenic) were almost indistinguishable between cells cultured in fetal bovine serum or cord blood plasma medium, while cells grown in cord blood plasma medium demonstrated significantly higher proliferation rates than those in medium containing fetal bovine serum. After thawing, the cells maintained their adherence to the culture surface and differentiation potential to osteoblasts, but cells from cord blood plasma cryopreservation medium showed significantly better plastic attachment and produced greater cellnumbers than fetal bovine serum for the first three post-thaw passages. The results demonstrate that cord blood plasma can sever as an effective substitute to fetal bovine serum for growth, maintenance and differentiation of umbilical cord mesenchymal stem cells, and thus it wil be a safe choice for clinical-scale production of human mesenchymal stem cells.

Objective To explore the molecular and cytogenetic abnormalities in multiple myeloma (MM).Methods The la-boratory data of bone marrow smears were retrospectively analyzed in 61 patients of MM.24 hours short-term culture of bone marrow and R banding technology were performed in 31 patients.Among these patients,10 cases were selected for de-tecting the IgH gene expression by the interval FISH method.Results The proportions of myeloma cells were 0.19~0.94 in bone marrow smears of 61 patients.In 31 patients,25 patients had enough metaphases for analysis,in which 19 cases (71.3%)had abnormal clones,8q24,11q13,13q14 and 17p13 were important structural abnormalities,where 14q32 rear-rangement was the most characteristic abnormal structure,6 patients were detected IgH gene rearrangement.Conclusion Bone marrow smear combined with other laboratory examinations could make the diagnosis of MM,chromosomal abnormali-ties may help to explore the pathogenesis of MM,and provide a theoretical basis for the early diagnosis,treatment and prog-nosis of this disease.
