BACKGROUND:To study the phenotypes of side population cells in leukemia is important for understanding the heterogeneity and origin of tumor cells, molecular markers and targeted therapy.
OBJECTIVE:To identify whether the human chronic myeloid leukemia cellline-K562 contains side population cells or not, and to further observe the differences in expressions of leukocyte differentiation antigens from side population cellsubset and non-side population cells subset.
METHODS:Flow cytometry was used to detect whether there were side population cells in the K562 celllines. Then, the expression of CD34+, CD34+CD38-, CD34+CD38+, HLA-DR+cells in the side population subsets and non-side population subsets.
RESULTS AND CONCLUSION:Flow cytometry results showed that the K562 cellline contained side population cells, and the proportion of side population cells was much lower. The side population cells accounted for (2.7±0.5)%of viable cells in K562. The expressions of CD34+cells and CD34+CD38-cells in the side population subset were significantly higher than those in the non-side population subsets. The expressions of CD34+CD38+cells and HLA-DR+cells in the side population subset and non-side population subset did not have a significant difference. Heterogeneity was found in the differentiation antigen expression between the side population subset and non-side population subset.

OBJECTIVETo investigate the clinical manifestations, pathological characteristics, and treatments of urothelial-type mucinous adenocarcinoma of the prostate (UMAP).

METHODSWe reported a case of UMAP, reviewed relevant literature, and analyzed the clinicopaothological features, diagnosis, treatment, and prognosis of the disease.

RESULTSThe patient was a 60-year-old male and underwent transurethral resection of the prostate for dysuria. Postoperative pathology indicated mucinous adenocarcinoma and sigmoidoscopy revealed no primary colon cancer. Immunohistochemical staining showed the negative expressions of PSA and P504s and positive expressions of CK7, CK34 β E12, CK20, and CDX2. Thus UMAP was confirmed and treated by intensity-modulated radiotherapy. Then the patient was followed up for 30 months, which showed desirable therapeutic result, with neither local progression nor distant metastasis.

CONCLUSIONUMAP has a bad prognosis and its diagnosis depends on pathological and immunohistocchemical examinations. It responds well to radical prostatectomy but is not sensitive to endocrine therapy. Radiotherapy can be considered for those who are not fit to receive radical prostatectomy.

OBJECTIVETo determine the effective dose of hepatitis B immunoglobulin (HBIG) for clearing maternally-transmitted hepatitis B virus (HBV) from a newborn.

METHODSFull-term neonates born to HBV-infected mothers were tested for hepatitis B surface antigen (HBsAg) and HBV DNA in venous blood, Individuals with positive results within two hours after birth were selected for study, and divided among two treatment groups: research group receiving HBIG continually adjusted to quantitative levels of neonatal HBsAg and HBV DNA levels; control group receiving standard HBIG 200IU dose. All neonates were also treated with 10 micrograms of recombinant vaccine. The decreases in HBsAg and HBV DNA over 12 months were comparatively analyzed between the two treatment groups.

RESULTSThe two treatment groups (HBIG adjusted vs. standard) were statistically similar in Apgar score (9.38+/-0.49 vs. 9.37+/-0.48), neonate body weight (3458.67+/-374.93 vs. 3558.61+/-322.85 g), maternal age (26.33+/-3.63 vs. 25.33+/-3.03), and initial HBsAg and HBV DNA levels (rank sum test Z = 1.381, and Z = 0.700, respectively) (all, P more than 0.05). Successful clearance of HBV infection within 12 months was achieved in significantly more neonates in the HBIG adjusted therapy group than in the standard therapy group (82.8% vs. 57.4%; x2 = 9.696, P less than 0.05).

CONCLUSIONAdjusting the neonatal HBIG dose according to HBsAg and HBV DNA levels can improve the success rate of clearing maternally-transmitted HBV.

OBJECTIVETo evaluate the impact of specific siRNA on survivin gene in transfected leukemia cells.

METHODThe small interfering RNA (siRNA) targeted survivin mRNA was synthesized in vitro and was transfected into K562 cell by Hiperfect into human leukemia cell line K562, which has high survivin expression level. The level of survivin mRNA expression was determined by quantitative reverse transcription polymerase chain reaction (RT-PCR) with SYBR GREEN I. The apoptosis index of cytotrophoblasts were determined and analyzed by FCM (Annexin V-FITC/PI staining methods). The cell proliferation was examined by MTT at 48 h and 72 h after transfection.

RESULTThe level of mRNA expression was significantly inhibited by the siRNA 48 h and 72 h after transfection, the suppression rate of survivin mRNA separately reached 85.21%, 94.35% mensurated by quantitative RT-PCR with SYBR GREEN I, cell proliferation was inhibited significantly by 45.02% and 50.88%, respectively, the apoptotic rate detected by Annexin V-FITC assay reached 12.28%and 21.55%, respectively.

CONCLUSIONThe chemosynthesized siRNA targeting survivin could significantly down-regulate survivin mRNA. Survivin siRNA was able to inhibit the proliferation of leukemia cell line K562. Survivin may become a new target for leukemia gene therapy.

This study was aimed to investigate the relationship between Richter's syndrome (RS) transformation and clinical characteristics as well as karyotype of patient with chronic lymphocytic leukemia (CLL). By the follow-up of a patient with CLL, the clinical characteristics, karyotype, treatment pattern and its effect, as well as disease progression were monitored regularly with serological test, flow cytometry and FISH technique. The results indicated that the patient typically presented with history of CLL at initial diagnosis, with expression of CD5(+), CD19(+) and CD23(+), Binet stage C, as well as karyotype aberration of trisomy 12, and poorly responded to 4 cycles of standard chemotherapy of FCR regimen. The disease progression was confirmed at 5 months with the symptoms of fever in the absence of infection, elevated lactate dehydrogenase level and rapidly enlarging lymphnodes which showed typically diffuse large B cell lymphoma by the biopsy. It is concluded that karyotype aberration of trisomy 12 is one of the risk factors for RS transformation, and treatment pattern of the patient with CLL may be associated with the transformation of RS.
