Abstract
Objective: To evaluate the efficacy of the Hodgkin lymphoma (HL)-2013 regimen in the treatment of children with HL, and to investigate the prognostic factors of childhood HL. Methods: Clinical data of 145 children (aged ≤18 years) with newly diagnosed HL, treated with HL-2013 regimen in 8 tertiary referral centers for childhood cancer from August 2011 to April 2021 were analyzed retrospectively. All the diagnosis were confirmed by histopathological morphology and immunohistochemical examination. The clinical characteristics and treatment outcomes were summarized, and the patients were divided into different groups according to clinical characteristics. Kaplan-Meier method was used for survival analysis, and the comparison of survival rates between groups was performed with Log-rank test. Results: Of the 145 cases, there were 115 males and 30 females, the age at diagnosis was 7.9 (5.8, 10.6) years. Cervical lymph node enlargement (114 cases, 78.6%) was the common symptom of the disease, and 57 patients (39.3%) were accompanied by large masses. The most common pathological classification was mixed cell type (93 cases, 64.1%). According to the Ann Arbor staging system, there were 9 cases of stage Ⅰ, 62 cases of stage Ⅱ, 45 cases of stage Ⅲ, 29 cases of stage Ⅳ. According to the risk stratification: there were 14 cases of low-risk group, 76 cases of medium-risk group and 55 cases of high-risk group. Of all patients, 68 cases (46.9%) achieved an early complete remission (CR) after 2 courses of chemotherapy, and the CR rate was 93.8% (136/145) after first-line treatment. Disease recurrence or progression occurred in 22 cases (15.2%). Of all patients, 125 cases survived, 6 cases died and 14 cases were lost to follow-up. Among the survived cases, 123 cases were continuously at CR state,and the follow-up time was 55 (40, 76) months. The 5-year overall survival (OS) and event free survival (EFS) rates were (95.3±1.9)% and (84.2±3.0)% for the entire group, respectively. 5-year OS and EFS rates for patients with stage Ⅲ-Ⅳ were both lower than those for patients with stage Ⅰ-Ⅱ (χ2=6.28 and 7.58, both P<0.05), the 5-year OS and EFS rates for patients in high-risk group were both lower than those for patients in low-risk and medium-risk group (χ2=10.93, 7.79, both P<0.05). The 5-year OS rates for the patient with early CR and without early CR were 100.0% and (90.9±3.6)% (χ2=5.77, P=0.016). EFS rates for the patient with early CR (68 cases) and without early CR (77 cases) were (93.8±3.0)% and (75.8±5.0)% (χ2=8.78, P=0.003). Conclusions: HL-2013 regimen is significantly effective in the treatment of pediatric HL. However, the patients in high-risk group and those without early CR are prone to disease recurrence or progression. Stage Ⅲ-Ⅳ and without early CR were associated with worse prognosis.

Abstract
Objective: To analyze the mutation type of FⅧ gene in children with hemophilia A and to explore the relationship among hemophilia gene mutation spectrum, gene mutation and clinical phenotype. Method: Sixty-two children with hemophilia A from Department of Pediatric Hematology, Tongji Hospital of Tongji Medical College, Huazhong University of Science and Technology between January 2015 and March 2017 were enrolled. All patients were male, aged from 4 months to 7 years and F Ⅷ activity ranged 0.2%-11.0%. Fifty cases had severe, 10 cases had moderate and 2 cases had mild hemophilia A. DNA was isolated from peripheral blood in hemophilia A children and the target gene fragment was amplified by PCR, in combination with the second generation sequencing, 22 and 1 introns were detected. Negative cases were detected by the second generation sequencing and results were compared with those of the international FⅧ gene mutation database. Result: There were 20 cases (32%) of intron 22 inversion, 2 cases (3%) of intron 1 inversion, 18 cases (29%) of missense mutation, 5 cases (8%) of nonsense mutation, 7 cases (11%) of deletion mutation, 1 case(2%)of splice site mutation, 2 cases (3%) of large fragment deletion and 1 case of insertion mutation (2%). No mutation was detected in 2 cases (3%), and 4 cases (7%) failed to amplify. The correlation between phenotype and genotype showed that the most common gene mutation in severe hemophilia A was intron 22 inversion (20 cases), accounting for 40% of severe patients, followed by 11 cases of missense mutation (22%). The most common mutation in moderate hemophilia A was missense mutation (6 cases), accounting for 60% of moderate patients. Conclusion: The most frequent mutation type in hemophilia A was intron 22 inversion, followed by missense mutation, again for missing mutation. The relationship between phenotype and genotype: the most frequent gene mutation in severe hemophilia A is intron 22 inversion, followed by missense mutation; the most frequent gene mutation in medium hemophilia A is missense mutation.

Abstract
We constructed a prokaryotic expression vector expressing the Mycobacterium tuberculosis protein TB16.3, as well as 3 other proteins, including TB15.3, CFP-10, and Rv2626C, which were purified and analyzed for their effectiveness as detection antibodies. The TB16.3 genes of M. tuberculosis H37Rv genomic DNA were amplified by polymerase chain reaction, inserted into the expression vector pET-30a, and expressed in Escherichia coli. An enzyme-linked immunosorbent assay was used to detect the 4 M. tuberculosis antibodies. Engineered E. coli bacteria expressing TB16.3 and the 3 other proteins were constructed and found mainly to be soluble. For recombinant TB16.3 proteins, serum samples of 118 tuberculosis (TB) patients and 96 healthy controls were analyzed. Sensitivity, specificity, and adjusted concordance rate for the TB16.3 antibody were 72.9, 86.5, and 79.6%, respectively. The positive rate of Rv2626C antibody in TB patients (44.1%) was significantly lower than that in normal controls (75.0%, χ(2) = 20.8, P < 0.01). TB15.3 and TB16.3 were used for simultaneous detection and showed sensitivity, specificity, and repeatability rates of 69.4, 96.9, and 83.7%. The antibody positive rate and specificity for patients with lung disease was 9.6 and 90.4%, respectively. TB15.3 and TB16.3 were mixed and detected simultaneously. Combined with the results for TB15.3, the sensitivity, specificity, and concordance rates were 82.2, 95.9, and 88.9%, respectively. The concordance rate was the highest value observed. Target genes were cloned into a host strain and expressed successfully. The TB16.3 recombinant protein may be used as a new serological antigen for tuberculosis diagnosis.

Abstract
We constructed a Mycobacterium tuberculosis vector expressing CFP-10 and Rv2626c to examine the expression of these proteins in Escherichia coli as well as their immunoreactivity. The CFP-10 and Rv2626c genes were amplified from tuberculosis H37Rv genomic DNA using polymerase chain reaction. They were ligated into the expression vector PET30a and expressed in E. coli. Histidine tag nickel column chromatography was used to purify the recombinant protein. An enzyme-linked immunosorbent assay (ELISA) was used for detection. In our E. coli-engineered bacteria containing a CFP10 and Rv2626c plasmid, the target protein was found mainly to be in the soluble form. We formed mixed antigens of the recombinant CFP10 and Rv2626c proteins. ELISA results showed that in 214 blood samples, the positive rate was 77.1%. The target gene was successfully expressed in the host strain. Mixed antigens of the recombinant CFP-10 and Rv2626c proteins can be used as a combination antigen in the serological diagnosis of tuberculosis.

Abstract
Rheological properties of blood, retinal capillary blood flow velocity and oxygen transport efficiency (TE) were measured and calculated from 21 type II diabetic patients (NIDDM) and 19 normal subjects. The results showed that the diabetes group had increased plasma viscosity and blood viscosities (P < 0.05 or better) at all tested shear rates. For both shear rates (gamma) of 225 sec-1 and 450 sec-1, the diabetes group displayed increased internal viscosity of red cells (Tk) (P < 0.002 and P < 0.001, respectively) but lower values of TE (P < 0.001, both). A lower value of retinal capillary blood flow velocity (P < 0.005) was also noted. Upon further analysis of possible relations between Hct values and Tk of red cells, it was found that Hct values were linearly correlated with Tk for both shear rates of the diabetes group (gamma = 225 sec-1 and gamma = 450 sec-1; R = -0.63 and -0.65, n = 21 and 19, respectively, both P < 0.005); control group (gamma = 225 sec-1 and gamma = 450 sec-1; R = -0.84 and -0.82, respectively, n = 19, both P < 0.001) and all subjects (gamma = 225 sec-1 and gamma = 450 sec-1; R = -0.70 and -0.72, n = 40 and 38, respectively, both P < 0.001). The impaired rheological properties of blood and internal viscosity of red cells may result in both reduced capillary blood flow velocities and less oxygen transported to tissues. This may possibly contribute to the deterioration of retinopathy or microangiopathy in diabetic patients.
