Abstract

Investigation of the 95% EtOH extract of stems of Dendrobium findlayanumafforded four new seco-dendrobines, findlayines A–D (1–4); two known dendrobines, dendrobine (5) and 2-hydroxydendrobine (6); and four new phenolic compounds, dendrofindlaphenols A–C (7, 9, and 10) and 6″-de-O-methyldendrofindlaphenol A (8). Compounds 1and 2are the first seco-dendrobines possessing a seven-membered lactam moiety, with 3and 4derived from the oxidative cleavage of the C-2–C-3 bond of dendrobine. The structures were established using spectroscopic methods and by comparison with literature data. The absolute configurations of 1–4were confirmed via single-crystal X-ray diffraction data. Cytotoxic activity assays against HL-60, SMMC-7721, A-549, MCF-7, and SW480 human cancer cell lines revealed IC50values ranging from 2.3 to 5.3 μM for compound 7, from 19.4 to 34.4 μM for 8, and from 49.4 to 96.8 μg/mL for the EtOAc extract. An assay of the inhibition of NO production with RAW 264.7 cells indicated that 8had an IC50value of 21.4 μM, and the EtOAc extract, 10.5 μg/mL. The EtOAc extract possessed DPPH radical scavenging activity of 69.93% at 100 μg/mL.

Abstract

Worldwide, prostate cancer (PCa) is the second most common malignancy in males. We undertook a meta-analysis to compare the efficacy and safety of conventional laparoscopic radical prostatectomy with a transperitoneal (TLRP) approach, versus that of an extraperitoneal (ELRP) approach, for treatment of localized PCa. A comprehensive literature search retrieved 14 publications, with a total of 1715 patients. Meta-analysis of these studies showed that an ELRP approach was associated with a significantly shorter postoperative catheterization time (MD: 1.99; 95% CI: 0.52 to 3.54; P = 0.008), less blood transfusion rate (OR: 2.05; 95% CI: 1.03 to 4.06; P = 0.04), shorter intestinal function recovery time (MD: 0.08; 95% CI: 0.52 to 1.09; P

Abstract

Objective: To analyze the expression and clinical characteristics of CD68 in bone marrow and peripheral blood of patients with acute myeloid leukemia (AML)., Methods: The expression of CD68 in bone marrow blast cells was detected by four-color flow cytometry in 50 newly diagnosed AML patients and 23 controls. The expression of CD68 in peripheral blood of 85 newly diagnosed AML patients, 29 remission AML patients and 24 controls was detected by ELISA. The correlation between the expression rate of non-M3 AML bone marrow CD68, peripheral blood CD68 concentration and white blood cell count and other clinical data was compared respectively., Results: The median CD68 expression rate in myeloid leukemia cells of non-M3 AML patients was 19.7%, significantly higher than control (0.2%) (P<0.001). The median concentration of non-M3 CD68 in peripheral blood was 67.97 pg/ml, significantly higher than in control (29.94 pg/ml)（P<0.01）. There was no statistically significant difference in the plasma CD68 concentration of the peripheral blood between the newly diagnosed (45.72 pg/ml) and the remission stage (55.12 pg/ml) of non-M3 AML patients by paired analysis (P>0.05). The results showed that the higher the expression rate of CD68 in bone marrow, the higher the count of white blood cells in peripheral blood, and the lower the count of hemoglobin and platelet in peripheral blood. The higher the plasma concentration of CD68 in peripheral blood, the higher the white blood cell count and the lower the complete remission rate., Conclusion: The expression of CD68 both in bone marrow and peripheral blood of patients with non-M3 AML is higher than that of control group. Patients with high expression of CD68 show a low rate of complete remission, suggesting that the expression level of CD68 is correlated with treatment response.

Abstract

Objective: To analyze the results of immunophenotyping in patients with acute T-lymphoblastic leukemia (T-ALL) so as to improve the understanding of early T-cell precursor acute T-lymphoblastic leukemia (ETP-ALL) and near ETP-ALL with elevated CD5., Methods: The results of immunophenotypes in 62 patients with newly diagnosed adult T-ALL in our hospital were retrospectively analyzed. According to the expression of CD5, CD1a, CD8 and My/S antigens, the patients were divided into 3 groups: ETP, near ETP and non-ETP. The immunophenotypic characteristics and basic clinical data of three groups were compared and analyzed., Results: There were significant differences in age, white blood cell and plt counts as well as percentage of bone marrow blasts among three groups (P＜0.05). ETP and near ETP mainly belonged to Pro T and pre T, and non-ETP mainly belonged to cortical T and mature T. The positive rates of My/S, CD1a, CD8 and CD5 were significantly different among three groups (P＜0.01). The positive rates of CD4 and CD3 in non-ETP group were significantly higher than those in ETP and near-ETP group (P＜0.01). The positive rate of CD56 in near-ETP group was 50%, which was significantly higher than that in ETP group (16.7%) and non-ETP group (0%) (P＜0.01)., Conclusion: According to the expression of CD5, CD1a, CD8 and My/S antigens, T-ALL patients can be divided into three groups: ETP, near ETP and non ETP, the immunophenotypes and basic clinical data among 3 groups are statistically different.

Abstract

Objective: To investigate the primary culture technique in vitro, and to evaluate the influence of the prostate donor age and the collagen coating on the primary prostatic cell culture., Methods: Three different methods (enzymic digestive method, tissue culture and enzymic digestive method combined with tissue culture) were investigated in the primary prostatic cell culture, the stromal cell were identified by immunocytochemistry., Results: Compared with the methods of digestion (either with or without tissue culture), tissue culture possessed better cellular adherence and proliferative ability. Thin coating of collagen on culture flask could improve the adherence of cell and promote cell proliferation. Prostate stromal cells from donors aged > or = 60 years old grew slower than those from donors aged < 60 years old., Conclusion: Tissue culture is a simple, convenience method for the primary benign prostatic hyperplasia(BPH) stromal cell culture. Thin coating of collagen in culture flask could improve the primary culture, and prostate stromal cells from donors aged < 60 years old are more suitable for stromal cell culture.
