Multiple myeloma is a monoclonal plasma cell malignant proliferative disease,accounting for about 10％ of malignaut tumors of blood system.In recent years,due to the application of hematopoietic stem cell transplantation and the application of MDT by combining new drug such as thalidomide,lenalidomide and bortezomib,the average survival of MM patients was significantly longer than before.The treatment strategy should be individualized before treatment according to the patient's age,physical condition and complications.In this paper,the treatment strategy of multiple myeloma patients were reviewed.

After the background, main contents and paper writers of the medical journal Yi Chao founded in Nanjing during the late period of Republic of China were analyzed with stress laid on its characteristics of nursing experiences and surgical treatment procedures for diseases, its historical values in studying the debate on traditional Chinese and Western medicine and the history of public health and medical cause during the period of Republic of China were elaborated.

Objective To find the frequencies of FcγRIIIA polymorphisms in Chinese people and the potential role of these polymorphisms(SNPs) in systemic lupus erythermatosus(SLE) and lupus nephritis(LN).Methods The investigation covers 324 unrelated Chinese SLE patients and 319 controls.FcγRIIIA F158V polymorphism was genotyped by specific primer-polymerase chain reaction(PCR).Results The frequency of F allele of FcγRIIIA polymorphism is 60.8% in Chinese people.FcγRIIIA polymorphism revealed a significant difference of both genotype and allele distribution in SLE patients and controls.LN patients have a significant increase in carrier frequency of the FF genotype, while the VV genotype reveals a significant decreased risk of early onset of LN.ConclusionsFcγRIIIA polymorphisms is potentially related with SLE in Chinese people.The homozygous FF genotype of FcγRIIIA might be the risk factor for LN, while the homozygous VV genotype might be the protective factor for late onset lupus nephritis.

Objective To evaluate the relationship between iodine intake and the prevalence of thyroid diseases in Urumqi.Methods A total of 1693 subjects were investigated.Serum thyroid hormones,thyroid autoantibodies,and urinary iodine concentration were determined,and type B ultrasonography of thyroid gland was performed in all participants.Result The urinary iodine level revealed that 9.5％ of the subjects were iodine deficient and 30.0％ iodine excessive.The average median urinary iodine was 254.9 μg/L.Serum total T4 level in the idione adequate and more than adequate groups was significantly higher than the other 2 groups [ ( 9.02±2.63 ) vs (7.69±2.85)、(8.45 ±2.13 ) μg/dl,both P＜0.05 ],and serum TSH level in the idione deficient group was significantly higher than the other 2 groups [ (3.00±1.86) vs (2.37±1.91),(2.27±1.86) mIU/L,both P＜0.01 ].There was no significant statistical difference in positive rates of thyroid autoantibodies,morbidities of thyroid dysfunction and goiter among 3 groups.Conclusion The iodine deficient situation has been corrected in Urumqi.There is no difference in morbidities of thyroid diseases in population with different iodine intakes.

A study program was worked out by analyzing the papers on Chinese drug prescriptions. A database of Chinese drug prescriptions was developed by automatic abstraction of data from the papers on Chinese drug pre-scriptions using the regular expression form in order to provide a new visual angle for studying the information in Chinese drug prescriptions.

Objective To study the application CT scans in Nuss procedure for pectus excavatum. Metlhods 648 children with pectus excavatum underwent Nuss procedure from July 2002 to September 2008 The preoperative CT scan was carried out for evaluation of the deformity degree and morphology classification of chest wall malformation, the deformity in relation with adjacent tissue and associated different disorder. Results Nuss procedure was successfully performed in all 648 patients. The preoperative CT scan showed medium deformity of the pectus excavatum in 73 cases ( 11.27% ) and severe deformity in 575 cases (88.73%). Morphologic classification of the pectus excavatum were symmetric type in 407cases (62.81% ) , eccentric type in 83( 12.81% ) ,and unbalanced type in 158( 24.38% ). 116 cases with pectus excavatum were associated with other different disorders, among them 55 cases ( 17.9% )were diagnosed by CT scan. 28 cases received stimultanously operation for their abnormalities. Conclusion CT scan is a useful tool for evaluation the deformity degree and morphology classification, direct the operation, reduce the complications and find other different disorders. It should be a routine examination before Nuss procedure.

Objective To study the expression of ?-catenin and cox-2 in the bulge cells of hair follicle and investigate the relationship of their expression on cell proliferation. Methods The hair follicle was prepared from the resected cheek skin of 20 Wistar rats aged 7 days. The bulge cells were resected from the intact hair follicle and cultured in vitro. Immunocytochemical technique (ICC) was applied to detect ?-catenin and cox-2 expression in bulge cells at culture day 3, 5, 8, 13. Results ?-catenin and cox-2 strongly expressed in bulge cells and the expression correlated with the culture days. ?-catenin appeared in both plasma and nucleus, while cox-2 only in nucleus. Conclusion ?-catenin and cox-2 were correlated with bulge cells proliferation, and cox-2 might be the target gene of ?-catenin signaling pathway in nucleus.

Objective To determine the effects of dose reduction on multi-slice spiral CT(MSCT) of neonatal head and assess the lowest possible radiation for acceptable clinical images.Methods Fifty-seven newborns suspected intracranial hemorrhage were entered into the study and underwent MSCT scans.Original images at three anatomic levels (posterior fossa, basal ganglia, centrum semiovale) were collected and synthetic noise was added so as to simulate dose reductions of 25%, 40%, 50% and 70%, respectively by using the noise addition tool.A total of 855 image data sets were obtained for the 57 patients.Original and simulated dose-reduction scan images were analyzed.Image noise and image quality were assessed by two independent experienced pediatric radiologists using diagnostic acceptability score, subjective image noise score on a 5-peint scale and objective noise index.Image noise was measured by respectively placing region of interest (ROI) at cerebellum, thalamus and corona radiata of 3 different slices.And the noise index and mean value was calculated.The degree of inter-observer concordance was determined by Kappa statistical analysis.The Spearman statistical correlations between the noise index and diagnostic acceptability score were performed.Results On the images of original dose and simulated dose reductions of 25%, 40%, 50% and 70%, the diagnostic acceptability was 4.47±0.51, 3.96±0.33, 3.21±0.45, 2.92±0.32, and 1.85±0.57, respectively,the subjective image scores were 1.62±0.48, 1.99±0.48, 2.76±0.81, 3.19±0.67, and 4.27±0.54, respectively, the noise index were 1.90±0.19, 2.17±0.20.2.44± 0.25, 2.68±0.28, and 3.37±0.39, respectively.The two radiologists had good intembserver agreement for diagnostic acceptability (K=0.860, P=0.017) and for image noise scoff ng (K=0.630, P=0.022).There was significant statistical correlation between image noise index and diagnostic acceptability (r= 0.826,P=0.001).At 40% dose reduction to the standard protocol, the noise index was 2.44 and the image quality score was 3.21 which were considered clinically acceptable.Conclusion The study revealed that acceptable imagos could be obtained with mean noise index of 2.44 and 40% dose reduction.
