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.

Objective To investigate the value of panel fluorescence in situ hybridization (panel FISH)for detection of genomic aberrations in chronic lymphocytic leukemia(CLL). Methods Five types of fluorescein-labelled DNA probes including five sequence specific probes D13S25 for 13q14. 3, RB1, p53, ATM (11 q23)and centromeric probe for chromosome (CSP12) were used to perform fluorescence in situ hybridization assays in 17 patients with CLL. Its results were compared with that obtain by conventional cytogenetic (CC)examination. Results In 17 patients with CLL, CC examination showed that only one case (1/17) was found to have chromosomal abnormality that was simultaneous trisomies 3,8 and 18, whereas panel FISH assay showed that 10 cases (10/17) were found to have genomic aberrations including deletion of D13S25 in 4 cases,deletion of ATM in 2 cases,deletion of p53 in 1 case,deletion of D13S25 combined RB1 in 1 case and 1 case with a variety of abnormalities. Conclusions Panel FISH is a useful method for detection of genomic aberration in CLL If it is combined with CC,it can obviously enhance the detection rate of chromosomal abnormalities in CLL.

Objective:
To construct a model for clinical identification of spotted fever (SF) and severe fever with thrombocytopenia syndrome (SFTS), so as to provide insights into early identification of SF and SFTS.
Methods:
The clinical data of laboratory-confirmed SF and SFTS patients in secondary and tertiary hospitals in Lu'an City, Anhui Province from May 2017 to May 2021 were retrieved from Chinese Disease Prevention and Control Information System. Factors affecting SF were identified using a logistic regression model, and the model for early identification of SF and SFTS was created. The model fitting effect was evaluated using Hosmer-Lemeshow test, and the value of the model for identification of SF and SFTS was evaluated using the area under the receiver operating characteristic curve (AUC).
Results:
Data of 62 SF cases and 115 SFTS cases were included. Multivariable logistic regression analysis showed that rash (β=5.994), C-reactive protein (β=4.409), white blood cell (β=-3.176) and platelet (β=-3.234) were included in the model, which were scored 6, 4, -3 and -3, with a total score ranging from -5 to 10. Hosmer-Lemeshow test revealed a high model fitting effect (χ2=3.245, P=0.662). The AUC of the model was 0.992, and the sensitivity and specificity were 0.935 and 0.991 if the cutoff was 1.
Conclusion
A model for early identification of SF and SFTS that includes four variables of rash, C-reactive protein, white blood cell and platelet has been created, which has a high accuracy.
