1.Genetic evolution and heterogeneity of multiple myeloma: a report from the 2013 EHA annual meeting
Journal of Leukemia & Lymphoma 2013;22(8):449-450,455
Recent studies have shown that multiple myeloma (MM) is preceded by a premalignant state called monoclonal gammopathy of undetermined significance (MGUS) and smoldering multiple myeloma (SMM).Some of the genetic changes of MM are also present in MGUS and SMM,including chromosomal translocations,copy number changes,somatic mutations and so on.This article discusses the genetic heterogeneity.

Objective To study the correlation between alopecia areata and the susceptibility genes identified in our previous study with Han Chinese population. Methods The study performed an independent replication study using 736 cases and 1 840 controls. DNA was extracted from peripheral blood leukocytes by salting out with saturat-ed NaCl solution according to standard methods. The evidence for association had been obtained from former gene study. Then a fine-mapping study and genotyped the locus with an additional 17 SNPs were performed. Data were analyzed with the use of Plink 1. 07 software. Results Only one SNP achieved nominal significance, rs3087243 (P = 0. 041, OR = 1. 18, 95% CI = 1. 01 ~ 1. 38). The other 16 genes (TLR1, DMBT1, CHIT1, GBP4, CIITA, IL31RA, CD96, INPPL1, MASP2, IL-13, KIAA0350, PTPN22, SPATA5, TRAF1 / C5, IL1A, IL2R) failed. A further stratification analysis of alopecia areata was adopted, including the analysis of family history, the age of on-set and the severity of alopecia areata. The stratification analysis revealed that the age of onset > 20 years achieved nominal significance P < 0. 05 for one SNP, rs2416808 (P = 0. 018, OR = 1. 35, 95% CI = 1. 05 ~ 1. 74), where-as, the other results were of no statistical significance. Conclusion The results indicate that 17 SNPs may not be associated with AA in Han Chinese population. Further study should be performed in a larger Han Chinese sam-ples.

Objective To investigate angiogenesis and mosaic vessel in colorectal carcinoma.Methods Forty-nine patients suffering from colorectal carcinoma were studied.Endothelial cell was labelled with monoclonal anti-human CD_~31 antibody,tumor cell was labelled with monoclonal anti-human CEA antibody.Endothelial cell and tumor cell were labelled by double-stained immunohistochemistry.The quantity of microvessel was estimated by counting microvessel density (MVD) at hot spots,and the quantity of mosaic vessels (MV) and double-stained cells were estimated at the same visual field.The relationship between mosaic vessels,microvessel density and Dukes staging were analyzed.Results The MVD in colorectal carcinoma "hot spots" was counted.The MVD of Dukes staging B was 43.98?21.46,staging C was 59.54?26.95,and staging D was 70.80?19.04.MVD increased gradually accompanied by clinical staging.There was statistical difference between staging B and D (P

Objective To study the expression and clinical significance of FoxM1 and Cep55 protein in basal-like breast carcinoma (BLBC).Methods The expression of FoxM1 and Cep55 protein in 66 cases of BLBC,70 cases of non-BLBC and 66 cases of normal adjacent breast tissue were detected by immunohistochemistry.Their relationship with the clinical pathological factors was analyzed.Results The positive rate of FoxM1 protein in BLBC,non-BLBC and normal adjacent breast tissue was 77.3% (51/66),60.0%(42/70) and 13.6%(9/66),Cep55 protein was 74.2%(49/66),57.1%(40/70) and 16.7%(11/66),respectively.BLBC and non-BLBC tissue were higher than normal adjacent breast tissue,and BLBC tissue was higher than non-BLBC,there was significant difference (P <0.05).In BLBC tissue,the positive expression of FoxM1 and Cep55 protein correlated with lymph nodes metastasis and TNM staging (P <0.05),while did not correlate with age,menopause,tumor size (P > 0.05).There was direct correlation between the positive expression of FoxM1 and Cep55 protein (r =0.259,P < 0.05).Conclusion FoxM1 and Cep55 protein may play an important role in the carcinogenesis and development of BLBC,and both of them have the synergistic effect.

Objective To investigate iodine nutritional status of pregnant women of Taizhou City,in order to provide a basis for assessment whether normal consumption of iodized salt is needed,to take complement iodine measure and to carry out monitoring of urinary iodine and thyroid function in pregnant women.Methods Early pregnancy (gestation < 4 months),medium (4 to 7 months gestation) and late (pregnancy≥8 months) of each of more than 300 pregnant women were chosen from maternal and child health (hospital) and part of the township hospitals of Taizhou City (district) from September 2012 to December 2013.Based on the principle of informed consent,disposable urine and blood samples were collected,urine iodine and thyroid hormone [serum thyroid stimulating hormone (TSH),three free triiodothyronine (FT3) and free thyroid hormone (FT4)] were measured.Urinary iodine was measured using a urinary iodine rapid quantitative detection kit,thyroid function was measured by an electrochemical method.Use 95% of the reference value range of thyroid function in pregnant women as the basis for evaluation of thyroid function in pregnant women.Results A total of 997 pregnant women were investigated,early stage,medium-term and late pregnancy women were 302,357 and 338,respectively.The median urinary iodine was 124,129,119 μg/L,pregnant women in late pregnancy had the lowest iodine urine.The median TSH of early stage,medium-term and late pregnancy women were 2.03,2.18,2.22 mU/L;the mean FT3 and FT4 of the three groups were (4.39 ± 0.66),(4.06 ± 0.61),(3.92 ± 0.61)pmol/L and (14.56 ± 2.56),(13.08 ± 2.03),(12.70 ± 2.38)pmol/L,respectively.The rate of abnormal thyroid function was 4.91% (49/977),mainly in subhypothyroidism [48.98% (24/49)].Conclusions Poor iodine-nutritional status exists in some pregnant women in Taizhou City.It is necessary to strengthen the propaganda and education of pregnant women on iodine supplement knowledge in the future,and carry out routine monitoring of urinary iodine and thyroid function in early pregnancy.

Objective To examine the relationships between a number of potential risk or protective factors and the risk of depression and anxiety among a population of adolescent elite athletes in Guangzhou city. Methods A whole sample was consisted of 520 students,and the information of their age,gender,characteristics and others was investigated. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scales(HADS). Data were analyzed using multiple stepwise regression analysis. Results After adjusting for other variables,students who had a high risk of anxiety were underweight (sβ =2.482) when compared to those who were of normal weight. Reduced risk of anxiety was associated with older students ( sβ = 4. 365), students with moderate educated mothersβ=3. 153) , and students who perceived very high pressure from teachers/coaches (sβ=5.372). A significant increase in the risk of depression was associated with variables including: students aged between 15 and 16 years(sβ =3.367) ,students who had a family history of chronic diseases (sβ =2.765) , and poor overall support(sβ = 4.365). Reduced risk of depression was associated with students with moderate educated mothers( sβ = 6.764) and students who perceived very high pressure from teachers/coaches(sβ = 4. 167). Conclusion Various risk and protective factors have been identified for anxiety and depression. These results have direct implications on the development of appropriate preventive strategies for mental problems among young elite athletes.
