OBJECTIVE: To investigate whether β-globin gene 3'UTR+101G>C (HBB:c.*233G>C) variant has genetic effect and provide basis for gene diagnosis and genetic counseling. METHOD: Whole blood cell analysis and capillary zone electrophoresis (CZE) were used to analyze the hematological indexes. The most frequent 23 mutations in southern Chinese individuals were routinely measured by PCR-flow fluorenscence immunmicrobeads assay. Sanger sequencing was used to detect the other variants of β-globin gene (HBB). RESULTS: In 463 cases, a total of 7 cases with HBB:c.*233G>C variant were detected, among them 4 cases carried other pathogenic variants of HBB gene (2 cases were in trans, 2 cases were in cis), who had typical hematological characteristics of mild β-thalassemia, and 3 cases also carried abnormal hemoglobin variation, but did not have hematological characteristics of β-thalassemia. CONCLUSION The study shows that HBB:c.*233G > C variant has no obvious genetic effect and should be a benign polymorphism.

OBJECTIVE: To analyze the hematological characteristics of Hb Broomhill and Hb Hornchurch, and prenatal diagnosis should be carried out in two families. METHODS: RBC parameters and hemoglobin electrophoretogram were analyzed on the peripheral blood of all patients, and amniotic fluid was collected for prenatal diagnosis. PCR-Flow fluorescent hybridization and Sanger sequencing were performed for gene diagnosis of thalassemia. RESULTS: Three cases of Hb Broomhill were detected, including 2 cases with common SEA α-thalassemia, which was characterized by hypochromic microcytic mild anemia, the capillary electrophoregram revealed a tiny shoulder peak before the Hb A peak; 1 case was diagnosed as Hb Hornchurch combined with β-thalassemia, which also showed mild anemia. Hemoglobin electrophoretogram showed an abnormal hemoglobin variant peak at Hb A CONCLUSION The carriers of Hb Broomhill and Hb Hornchurch do not have microcytic hypochromic anemia, which do not aggravate the hematological symptoms, such as anemia when being combined with thalassemia of the same type.

OBJECTIVE: To perform genetic analysis, prenatal diagnosis and preimplantation genetic diagnosis (PGD) in a family with a rare deletional β- thalassemia. METHODS: Hematological parameters of the peripheral blood collected from all the family members were analyzed by whole blood cell analysis and capillary zone electrophoresis (CZE). Polymerase chain reaction-reverse dot blot (PCR-RDB) was used to identify 17 common β- thalassemia gene mutations, the multiplex ligation-dependent probe amplification (MLPA) and gap-polymerase chain reaction (gap-PCR) were used to identify β- globin gene cluster deletions. Chorionic villus sample or umbilical cord blood was obtained for prenatal diagnosis. Oligo-cells from blastocyst biopsy were collected for preimplantation genetic diagnosis by whole genome amplification and next generation sequencing. RESULTS: The proband was a carrier of Taiwanese deletion β- thalassemia, two fetuses were both thalassemia majors. The PGD results showed that 6 of 11 tested embryos could be choose for transplantation. CONCLUSION The Taiwanese deletion is a rare type deletion of β- globin gene cluster, and it can lead to thalassemia intermedia or thalassemia major when compounded with other β- globin gene mutation. PGD is another choice for thalassemia couples.

OBJECTIVETo study the value of absolute lymphocyte count/absolute monocyte count (ALC/AMC) and its effect on prognosis in patients with primary follicular lymphoma treated with rituximab combined with cyclophosphamide + doxorubicin + vincristine + prednisone (R-CHOP) chemotherapy.

METHODSSeventy patients with primary follicular lymphomawere in our hospital were treated with R-CHOP chemotherapy, the ALC/AMC value of peripheral blood was recorded, and the prognosis was assessed by the international prognostic index.

RESULTSAccording to the scores of the international prognostic index, 30 (42.86%) patients with score of 0-1 were enrolled in low-risk group, 21(30.00%), patients with score of 2 were enrolled in as the intermediate-risk group and 19 patients(27.14%) with score of 3-5 were enrolled in high-risk group. In the 3 group, the total effective rate of the low-risk group was the highest (95.24%), second was the intermediate-risk group (86.67%) and the total effective rate of the high-risk group was the lowest (78.95%), which showed that the difference was statistically significant (P<0.05); the progression-free survival(PFS) rate of 3 years in the low risk group was the highest (90%), followed by the intermediate-risk group (76.19%), and the PFS rate of the high-risk group was the lowest (52.63%)(P<0.05). The total effective rate of ALC/AMC<4.7 group was significantly lower than that of ALC/AMC ≥4.7 group (68.63% vs 89.47%) (P<0.05), and the PFS rate of 3 years was lower than that of ALC/AMC≥4.7 group (70.59% vs 89.47%) (P<0.05). Multivariate analysis revealed that ALC/AMC value in the peripheral blood was an independent prognostic factor for patients with follicular lymphoma (P<0.05).

CONCLUSIONThe value of ALC/AMC in the peripheral blood may be an important marker for evaluation of prognosis in patients with primary follicular lymphoma treated with R-CHOP chemotherapy, which helps to assess the patient' s immune and tumor microenvironment.

OBJECTIVETo analyze the whole microbial structure in a case of rampant caries to provide evidence for its prevention and treatment.

METHODSClinical samples including blood, supragingival plaque, plaque in the caries cavity, saliva, and mucosal swabs were collected with the patient's consent. The blood sample was sent for routine immune test, and the others samples were stained using Gram method and cultured for identifying colonies and 16S rRNA sequencing. DNA was extracted from the samples and tested for the main cariogenic bacterium (Streptococcus mutans) with qPCR, and the whole microbial structure was analyzed using DGGE.

RESULTSThe patient had a high levels of IgE and segmented neutrophils in his blood. Streptococci with extremely long chains were found in the saliva samples under microscope. Culture of the samples revealed the highest bacterial concentration in the saliva. The relative content of hemolytic bacterium was detected in the samples, the highest in the caries cavity; C. albicans was the highest in the dental plaque. In addition, 33 bacterial colonies were identified by VITEK system and 16S rDNA sequence phylogenetic analysis, and among them streptococci and Leptotrichia wade were enriched in the dental plaque sample, Streptococcus mutans, Fusobacterium nucleatum, and Streptococcus tigurinus in the caries cavity, and Lactobacillus in the saliva. S. mutans was significantly abundant in the mucosal swabs, saliva and plaque samples of the caries cavity as shown by qPCR. Compared to samples collected from a healthy individual and another two patients with rampant caries, the samples from this case showed a decreased bacterial diversity and increased bacterial abundance shown by PCR-DGGE profiling, and multiple Leptotrichia sp. were detected by gel sequencing.

CONCLUSIONThe outgrowth of such pathogenic microorganisms as S. mutans and Leptotrichia sp., and dysbiosis of oral microbial community might contribute to the pathogenesis of rampant caries in this case.

OBJECTIVETo investigate the effects of different hemapheresis procedures on the components of hematopoietic stem cells(HSCs) collected from helathy donors.

METHODStwelve donors were underwent stem cell collection from January 2015 to August 2016, and the stem cells were randomly colleted by AutoPBSC procedure of COBE spectra and MNC procedure of the Spectra Optia blood cell separator, the mononuclear cells, CD34cells, granulocytes, lymphocytes and platelets in the collections were compared.

RESULTSThe circulating blood volume, the acquisition time and dosage of anticoagulants were not significantly different between two procedures. The volume and the mononuclear cell count collected by AutoPBSC procedure were lower than those by the MNC procedure, while the CD34cell count by AutoPBSC procedure was higher than that by the MNC procedure. More lymphocytes and platelets were collected by AutoPBSC procedure as compared with that by the MNC procedure (P<0.05).

CONCLUSIONCompared with MNC procedure of the Spectra Optia blood cell separator, the number of collected stem cells, lymphocytes and platelets are higher by using AutoPBSC procedure of the COBE spectra blood cell separator.

OBJECTIVETo investigate the difference in the vulnerability of carotid atherosclerotic plaques in patients with unilateral and bilateral intraplaque hemorrhage (IPH).

METHODSA retrospective analysis was conducted among 44 patients with unilateral IPH (30 cases) or bilateral IPH (14 cases) in the carotid plaques detected by magnetic resonance imaging (MRI) in our hospital between December, 2009 and December, 2012. The age, maximum wall thickness and incidence of fibrous cap rupture were compared between the two groups.

RESULTSCompared with those with unilateral IPH, the patients with bilateral IPHs had a significantly younger age (66.6∓9.4 years vs 73.7∓9.0 years, P=0.027), a significantly greater maximum plaque thickness (6.3∓1.9 mm vs 5.0∓1.3 mm, P=0.035) and a higher incidence of ulcers (50% vs 13.3%, P=0.025). Logistic regression analysis revealed a significant association between bilateral IPHs and the occurrence of ulcer with an odd ratio (OR) of 6.5 (95% confidence interval [CI]: 1.5-28.7, P=0.014). After adjustment for gender in Model 1, bilateral IPHs were still significantly associated with presence of ulcer (OR=5.7, 95%CI: 1.1-29.2, P=0.036). But after adjustment for age (P=0.131) or maximum plaque thickness (P=0.139) in model 2, no significant correlation was found between bilateral IPHs and the presence of ulcer.

CONCLUSIONCompared with patients with unilateral IPH, those with bilateral IPHs are at a younger age and have a greater plaque burden and a higher incidence of fibrous cap rupture, suggesting a greater vulnerability of the carotid plaques in patients with bilateral IPHs.
