Objective To investigate the clinical significance of I-FISH for detection of genomic abnormalities in MM. Methods Twenty newly diagnosed MM patients(seven cases at stage Ⅰ , five cases at stage Ⅱ and eight cases at stage Ⅲ according to Bataille staging) were analyzed by combining the technique of CC (R-binding stain) and I-FISH [ including GLP13q14 (RBI gene), GLP17p13. 1 (P53 gene),GLP13q14. 3(D13S319) ,GLP1q21 ,GLP14q32(IgH gene) DNA sequence probes]. These two methods were compared for the detection rates of chromosomal and genomic abnormalities in MM and the association between genomic abnormalities and Bataille stages was also analyzed. Results CC examination showed only 1 case [5% (1/20) ] was found complex chromosomal abnormalities--46,XX,-2,del(3) (p21) ,add(6)(q26) ,der(10)(q26),der(14)(q32), + mar, inc[6]. While I-FISH assay showed that 12 cases [60%(12/20) ] were found genomic abnormalities. The frequencies of RB1, D13S319 and P53 were all 30%(6/20), and the frequencies of IgH gene and 1q21 were both 20% (4/20). The detection rate of the I-FISH was much higher than CC (χ2 = 9. 09, P = 0. 001) according to paired χ2 test. Of 20 patients,6 cases had RB1 gene abnormality, 1 case at stage Ⅰ , 2 cases at stage Ⅱ and 4 cases at stage Ⅲ. Of 20 patients, 6 cases had D13S319 gene abnormality, 2 cases at stage Ⅰ , 1 case at stage Ⅱ and 3 cases at stage Ⅲ. Of 20 patients, 6 cases in 20 had P53 gene abnormality, 2 cases at stage Ⅰ and 4 cases at stage Ⅲ. Of 20 patients, 4 cases had 1q21 gene abnormality, 2 cases at stage Ⅰ and 2 cases at stage Ⅲ. Of 20 patients, 4 cases had IGH gene abnormality, 1 case at stage Ⅰ and 3 cases at stage Ⅲ. Conclusion Ⅰ-FISH has higher detection rate for the genomic abnormalities in MM and can be used in detection of MM patients in different Bataille stages.

Stromal preadipocytes from human omental adipose tissues were isolated with enzyme-digesting method,and cultured for inducing differentiation.Preadipocyte factor-1 was abundant during preadipoeyte stage,whereas lipoprotein lipase and PPARγ2 mRNA were rapidly up-regulated at early stage of differentiation and CCAAT/enhancer binding protein expression was increased rather late.In addition,resistin expression and secretion was primarily detectable in preadipocytes,leptin was gradually increased during adipogenesis,whereas adiponectin appeared specifically in mature adipocytes.Insulin-like growth factor-Ⅰ secretion was remarkably detected in both preadipocytes and mature adipocytes.

OBJECTIVE: To observe the therapeutic effect of salvia miltiorrhiza and prednisolone on patients with oral submucous fibrosis (OSF). METHODS: A total of 60 medium-term OSF patients and 60 advanced stage OSF patients were randomly divided into the first group (treated with both salvia miltiorrhiza and prednisolone) and the second group (treated with prednisolone alone). The clinical effect was compared between each group after 3-month treatment. RESULTS: Difference was found in the lesion area of the medium-term cases and the advanced stage cases of the first group before the treatment [(10.37+/-3.40) cm2, (19.60+/-3.27) cm2] and after the treatment [(5.90+/-4.10) cm2, (16.33+/-4.02) cm2] (P<0.05). Significant difference was found in the mouth opening before the treatment [(3.41+/-0.77) cm, (1.98+/-0.39) cm] and after the treatment [(3.87+/-0.67) cm, (2.26+/-0.46) cm] (P<0.05) in the first group. There was significant difference in the lesion area and mouth opening of the medium-term cases of the second group before the treatment [(10.87+/-3.18) cm2, (3.57+/-0.75) cm] and after the treatment [(6.70+/-3.75) cm2, (3.97+/-0.69) cm] (P<0.05). No difference in the lesion area and mouth opening of the advanced stage cases of the second group was found (P>0.05). There was difference in the therapeutic efficacy between the first group (70%) and the second group (16.67%) of the advanced stage cases (P<0.05), but not in the clinical effect between the 2 groups of the medium-term cases (P>0.05). The side effect of prednisolone could be reduced while used together with salvia miltiorrhiza. CONCLUSION There is obvious advantage in treating OSF by the combination of salvia miltiorrhiza and prednisolone.

Objective: To investigate the etiological characteristics of Streptococcus pyogenes that caused scarlet fever from 2012 to 2016 in Tianjin. Methods: The subjects were children diagnosed clinically as scarlet fever in Tianjin scarlet fever monitoring hospital from 2012 to 2016. The exclusion criteria were children with scarlet fever who were unable to cooperate with sampling. A total of 575 cases of children's swabs were collected. Biochemical methods were used to isolate and identify the bacteria of pharynx swab, and the PCR method was used to detect the emm genotyping and superantigen speA and speC, and the resistance of the strains to 10 antibiotics was measured by K-B paper method. We compared the carrying status of superantigen genes by different types of GAS and the resistance of all GAS to different antibiotics. Results: There were 5 emm types (emm1/11/12/22/89). The dominant types were emm12 (52.9%, 100 strains) and emm1 (44.4%, 84 strains). The carrying rates of speA and speC genes were 21.7% (41 strains) and 76.7% (145 strains), respectively. The speA gene carrying rate of emm1 type GAS was 33.3% (28 strains), which were higher than that of emm12 (12% (12 strains)) (χ²=12.21, P<0.001). The speA and speC gene simultaneous carrying rate of emm1 type GAS was 27.4% (23 strains), which was higher than that of emm12 type (12% (12 strains)) (χ²=7.01, P=0.008). The percentages of the strains that were resistant to Azithromycin, Erythromycin, Clarithromycin, Clindamycin, Tetracyclin, Levofloxacin and Chloramphenicol were 96.8% (183 strains), 96.3% (182 strains), 92.1% (174 strains), 92.1% (174 strains), 73.0%(138 strains), 2.1% (4 strains) and 1.6% (3 strains), respectively. All isolates were susceptible to Penicillin, Cefazolin and Vancomycin, and there were statistical significance (χ²=953.28, P<0.001). Conclusion The dominant emm types causing scarlet fever are emm12 and emm1. The frequencies of speA and speC in emm1 and emm12 are different. S.pyrogenes in Tianjin were susceptible to penicillin, cefazolin and vancomycin, but highly resistant to the clindamycin, clarithromycin, erythromycin and azithromycin.

Objective To study the safe dose of Ginseng (Radix et Rhizoma Ginseng) through analysis of literature from Tang dynasty (618 AD) to Republic period(1949 AD).Methods The selection strategy for literature and prescriptions was made to acquire the formulae in need.The authoritative prescription-books from Tang Dynasty to Republic period,or representative books of the renowned doctors who was good at using Ginseng in that period were chosen.From the books above mentioned,prescriptions with Ginseng to tranquilize mind were included,in which insomnia and/or dreaminess were recorded as symptoms or clinical applications.Prescriptions without definite dose or only with dose for children were excluded.All herbal names were standardized according to current TCM terms.Then the maximum,minimum,frequency and 80％ confidence interval of dose were studied.The dose range of Ginseng in deferent dosage form was discussed according to above data.Results Fourteen classical TCM books were included,from which 85 formulae were studied.In the form of root slices decoction,the applied daily dose of Ginseng ranged from 3.73 g to 18.65 g,while in the formulae with symptom of dreaminess,the dose ranged from 7.46 g to 11.19g.In the form of root powder decoction,the single dose range was 0.07 g to 5.16 g,while in the formulae with symptom of dreaminess,the dose range was 1.03 g to 4.45 g.In the form of pill or powder,the single dose range was 0.68 g to 6.54 g,and 12％ to 30％ in total dose of the prescription.Conclusion For the root slices decoction,the favorable dose range of Ginseng is between 7 g and 11 g,but not more than 18.00 g per day.For the root power decoction,the favorable dose range is from 1 g to 4.00 g,and the maximum single dose is 5.00 g.For pill or powder form,the maximum dose is 6.00 g,taking 12％ to 30％ in total prescription.

Objective To analyze the characteristics of antibiotic resistance in group A Streptococ-cus ( GAS) strains isolated from children with scarlet fever in Tianjin in order to provide reference for clinical drug administration. -ethods GAS strains were collected from 2011 to 2016. A total of 276 isolates were analyzed by antibiotic susceptibility test and emm typing. Results All of the isolates were susceptible to penicillin, cefazolin and vancomycin, while 98. 2％ were susceptible to both chloramphenicol and levofloxa-cin. The resistance rates to azithromycin, erythromycin, clarithromycin, clindamycin and tetracycline were 97. 8％, 97. 1％, 94. 2％, 94. 2％ and 79. 3％. The concomitant resistance to erythromycin, azithromycin, clarithromycin, clindamycin and tetracycline was 73. 2％. The resistance rates of GAS strains isolated from different years to tetracycline, clindamycin, clarithromycin, erythromycin and azithromycin were significantly different. A statistically significant difference was found between the percentages of emm12 and emm1 strains resistant to tetracycline (84. 0％ vs 59. 5％, χ2=13. 820, P=0. 000). Conclusions The isolated GAS strains are sensitive toβ-lactams and highly resistant to macrolide antibiotics, clindamycin and tetracycline. Penicillin remains the preferred treatment for GAS infection and cephalosporins may be used as a substitute if the patient is allergic to penicillin.

Transrectal contrast-enhanced ultrasound (CEUS) is an important examination for rectal tumors. The inhomogeneity of the CEUS images has important clinical significance. However, there is no objective method to evaluate this index. In this study, a method based on gray-level co-occurrence matrix (GLCM) is proposed to extract texture features of images and grade these images according the inhomogeneity. Specific processes include compressing the gray level of the image, calculating the texture statistics of gray level co-occurrence matrix, combining feature selection and principal component analysis (PCA) for dimensionality reduction, and training and validating quadratic discriminant analysis (QDA). After ten cross-validation, the overall accuracy rate of machine classification was 87.01%, and the accuracy of each level was as follows: Grade Ⅰ 52.94%, Grade Ⅱ 96.48% and Grade Ⅲ 92.35% respectively. The proposed method has high accuracy in judging grade Ⅱ and Ⅲ images, which can help to identify the grade of inhomogeneity of contrast-enhanced ultrasound images of rectal tumors, and may be used to assist clinical doctors in judging the grade of inhomogeneity of contrast-enhanced ultrasound of rectal tumors.

OBJECTIVETo explore the clinical features and survival of patients with CD56 expression in de- novo acute myeloid leukemia（AML）with t（8;21). .

METHODSClinical data of 82 de novo AML with t（8;21）who were newly diagnosed from Jan 2008 to Apr 2014 were analyzed retrospectively, 50 expressed CD56 and 32 not. Clinical characteristics and prognoses were compared between patients expressing and nonexpressing CD56.

RESULTSThere were no statistically significant differences in terms of age, gender, white blood cell count（WBC）, percentage of bone marrow blasts, extramedullary infiltration rate, the early mortality or the presence of additional cytogenetic abnormalities between CD56 + and CD56- groups（P＞0.05). The expressions of lymphatic antigens CD19 between CD56 + and CD56- groups showed significant difference （30.0% vs 53.1% , P=0.036). The complete remission and 3-year overall survival（OS）showed no significant differences between CD56+ and CD56-groups, while 3- year disease- free survival（DFS）showed significant differences（25.8% vs 46.9%, P=0.014). Multivariable analysis for DFS identified CD56 positivity as an independent predictor. DFS of who received allogeneic hematopoietic stem cell transplantation（HSCT）was better than those treated with intermediate- dose cytarabine/high dose cytarabine（IDAC）as postremission therapy.

CONCLUSIONThe expression of CD56 in de-novo AML with t（8;21) appeared to be associated with poorer prognosis.
