2.Effects of 8-bromo-7-methoxychrysin and sorafenib on apoptosis of liver cancer stem-like cells
Chinese Journal of Tissue Engineering Research 2015;(45):7263-7267
BACKGROUND:We tried to combine 8-bromo-7-methoxychrysin and sorafenib in order to offset the tolerance of hepatocelular cancer stem cels to sorafenib, thereby comprehensively improving the therapeutic efficacy on hepatocelular carcinoma. OBJECTIVE:To observe the effects of 8-bromo-7-methoxychrysin, sorafenib and their combination on apoptosis of liver cancer stem-like cels SMMC-7721, and to analyze their mechanisms. METHODS:SMMC-7721 cels were treated with 8-bromo-7-methoxychrysin, sorafenib alone and their combination for 24 hours. Then, flow cytometry was used to detect cel apoptosis and western blot assay was used to determine nuclear factor-κB protein expression. RESULTS AND CONCLUSION:Compared with 8-bromo-7-methoxychrysin group and sorafenib group, the apoptotic rates of SMMC-7721 cels were significantly enhanced after treatment with the combination of 8-bromo-7-methoxychrysin group and sorafenib (2.5, 5, 10, 50 μmol/L), and meanwhile, the protein expression of nuclear factor-κB was down-regulated significantly. These findings indicate that the combined therapy of 8-bromo-7-methoxychrysin group and sorafenib can enhance the apoptosis of SMMC-7721 cels, which may be associated with down-regulation of nuclear factor-κB protein.

Objective To observe the impact of the five-emotion restrictive therapy on coronary heart disease. Methods109 hospitalized patients with coronary heart disease were randomly divided into a experimental of 56 patients and a control group of 53 patients according to length of stay. The control group was treated with the conventional therapy; the experimental group was imposed five-emotion restrictive psychological intervention on the basis of conventional therapy. The investigation was done using self-rating anxiety scale(SAS) and self-rating depression scale(SDS) on 1 day after admission and ld before discharge respectively. SAS and SDS scores were surveyed. At the same time Holter monitoring and normal ECG test were compared. Results Compared with control group, the experimental group 1 d before discharge of the SAS and SDS scores were (41.9±7.4) and (38.6±8.4), and the difference was statistically significant (P<0.01) . The total effective rate of Holter monitoring and normal ECG was 64.15% and 92.85% in the control and experimental group, and the difference was significant (P<0.01) . ConclusionThe pathological seven emotions have a certain affection on the incidence of coronary heart disease, treatment and prognosis of the course. Five-emotion restrictive psychological intervention can adjust timely psychological state of patients, eliminate negative emotions, and significantly help the incidence, treatment and prognosis of the disease.

ObjectiveTo discuss the application value of high frequency ultrasound (HFUS) characteristics, acoustic radiation force impulse (ARFI) imaging technology and contrast-enhanced ultrasound (CEUS) in the diagnosis of soft tissue hemangioma.MethodsTo retrospectively analyze the clinical data of 44 cases of soft tissue hemangioma that were treated in Capital Medical University Affiliate Beijing Chaoyang Hospital from August, 2013 to May, 2014, and to analyze the difference between the characteristics of HFUS, ARFI and CEUS in soft tissue hemangioma and normal surrounding tissue.ResultsHFUS shows the features of morphological diversity of sinus shape expansion tube structure, unclear boundary, irregular configuration, compressibility and partial strong echo in the phlebolith. Color Doppler ultrasound (CDFI), detects abundant interphase red-blue bloodstream signal slowly and consistently. The blood signal is strengthened after partial compression. CDFI shows more vein spectrum in the lesion. The discrepancy of comparison between VTQ and SWV value of soft tissue hemangioma and surrounding muscular tissue possesses statistical significance [(1.082±0.183) m/svs (1.414±0.331) m/s,P<0.01]. Ultrasound contrast can show the relationship between diseased region and surrounding tissue clearly, which is beneficial to the selection of operation method and prognosis.ConclusionThrough conventional two-dimensional ultrasound and high frequency CDFI, and further combining the acoustic pulse radiation ARFI technology and CEUS technology, the soft tissue hemangioma can’t only be more accurately diagnosed, but also provides more reliable diagnostic basis for clinic.

Objective To investigate the expression of miR-30d in breast cancer tissues and demonstrate the regula-tive effects of miR-30d ASO on the invasion and migration of breast cancer cells in vitro. Methods The expression levels of miR-30d in 108 breast cancer tissues and their adjacent tissues were detected by real-time quantitative PCR method. Af-ter transfection with miR-30d ASO, the biological effects of miR-30d on in breast cancer cells was measured by transwell as-say and wound healing assay. The expressions of matrix metalloproteinase (MMP)-2 and MMP-9 were analyzed by Western blot assay. Results The expression level of miR-30d was found to be over-expressed in breast cancer tissues(P<0.05). Compared with control group and nonsense interference group, the miR-30d expression was significantly decreased in breast cancer cells(transfection with miR-30d ASO). Results of transwell and wound healing assay showed that the invasion and mi-gration ability decreased significantly after transfection with miR-30d ASO, and expressions of MMP-2 and MMP-9 were down-regulated (P<0.05). Conclusion miR-30d was over-expressed in human breast cancer. The invasion and migration of breast cancer cells can be effectively inhibited by decreasing the expression of miR-30d. miR-30d may become a new tar-get for the regulation of invasion and migration in breast cancer.

Objective To analyze the clinical characteristics,treatment and prognosis of primary lymphoma of bone (PLB).Methods Retrospective analysis of 9 cases with newly diagnosed PLB was performed.The primary lesion was located in bone and no evidence of lesion was found in other tissues.All the lesions were confirmed by histological examination and immunohistochemical staining.The clinical manifestation and radiological appearance of all cases were non-specific.Results 9 patients were enrolled in the current study including 6 males and 3 females with average age of 34 years old (15-71 years old).All cases had suffered local pain or edema as initial symptom.Single bone infiltration was detected in 7 patients,while multiple bones infiltration was noticed in 2 patients.The lesion distribution was as follows:4 lesions were situated in pelvis (3 in ilium and 1 in sacral),1 in femur,1 in humerus,1 in scapula,and 2 in spine.2 cases were treated with radiotherapy and chemotherapy,3 cases were treated with chemotherapy and hematopoietic stem cell transplantation,1 case was treated with chemotherapy and surgery,and 3 cases received chemotherapy alone.With in a median follow-up of 8 months,6 patients showed overall response (including 5 cases of complete response and 1 case of partial response).Conclusions PLB is a rare condition,and the diagnostic criteria and treatment are still not well defined.Early diagnosis and prompt treatment usually achieves satisfactory prognosis.The possibility of PLB must be concerned for patients with bone pain,soft tissue swelling or unexplained fractures,and pathological examination should be carried on as soon as possible.
