Objecave The effects of PGF2α on the reactive oxygen species generation and cardiomyocyte hypertrophy were examined in experiments on the cultured neonatal rat cardiomyocytes.It is to study the role of ROS in the signaling pathway of cardiomyocyte hypertrophy induced by PGF2α.Methods The level of intracellular ROS wag measured by the ROS-specific probe 2',7'-dichlorofluorescin diacetate (DCF-DA).Cardiomyocyte hypertrophy was determined by total protein content of the cells and the cell diameter.Results In the cardiomyocytes treated with PGF2α(1nmol/l,10nmol/l,100nmol/l),the fluorescence intensity of intracellular DCF-DA increased by 38.99%,61.76% and 93.55% respectively compared with control group(F=195.69,P＜0.01).It is indicated that PGF2α can induce intracellular ROS generation on the cultured neonatal rat cardiomyocytes in a dose-dependent manner.Compared with control group,the total protein increased by 39.51%, 69.93%and 139.06%respectively(F=74.014,P＜0.01),and the cell diameter increased by 29.02%,60.79%and 127.40%respectively(F=721.02,P＜0.01).It is indicated that PGF2α induce cardiomyocyte hypertrophy on the cultured neonatal rat cardiomyocytes in a dose-dependent manner.Conclusion PGF2α can induce intracellular ROS generation and cardiomyocyte hypertrophy on the cultured neonatal rat cardiomyocytes in a dose-dependent manner.

Long non-coding RNA urothelial carcinoma associated 1 (UCA1) is initially discovered and named in bladder cancer tissue,which is highly expressed in multi types of tumor tissues,such as bladder cancer,ovarian cancer,lung cancer,suggesting that UCA1 acts as oncogene.UCA1 is confirmed to regulate tumor cell proliferation,apoptosis,invasion and migration,which plays an important role in the occurrence and development of cancers.UCA1 is expected to become a new biomarker for diagnosis,prognosis and drug susceptibility,which may be a promising therapeutic target of cancer.

Objective To improve a HPLOUV method for the determination of Tramadol hydrochlo-ride in human plasma. Method Alkalinized samples of plasma were extracted with dichloromethane. Tramadol and internai standard were analyzed on Elite C18 column (200mm?5.0mm, 5?m) with a acetoni-trile-phsphate buffer (pH6.5) (74:26, v/v) mobile phase and detedted at 220nm. Results The Calibra-tion plots in human plasma were linear (r=0.9984, n =5) from 10 to 800 ng/ml. The limit of detection was 10 ng/ml. For 20, 100, 400 ng/ml check samples, intra-run precisions (RSD) were 3.81% -5.44% and inter-run preceisions (RSD) were 3.95% -4.41% , respectively. The average recoveries were 89% , 96% and 92% for the low, middle and high check samples, respectively. Conclusion The improved ana-lytical method for Tramadol hydrochloride was found to be sensitive, simple and rapid, suitable for applica-tion in forensic toxicological analysis and routine determination of numerous samples.

Objective To evaluate the therapeutic effects,acute and late side-effects of cisplatin plus 5-fluorouracil (PF) schemed chronomodulated chemotherapy combined with concurrent intensitymodulated radiotherapy(IMRT) for nasopharyngeal carcinoma.Methods A total of 48 nasopharyngeal carcinoma patients treated with chronomodulated chemotherapy plus concurrent IMRT were retrospectively studied.The radiation doses prescribed to the gross target volume GTVnx of nasopharyngeal,to the positive neck lymphnodes GTVnd,to the clinical target volume CTV1,and to CTV2 were 73.92-77.88,69.96,60.06-66.00 and 50.96-56.00 Gy respectively.The Kaplan-Meier survival analysis was used to calculate the local-regional progression-free rate.The acute and late side-effects were graded according to RTOG radiation morbidity scoring criteria.Results The complete remission (CR) rate was 41.6％(20/48) ; the partial remission (PR) rate was 47.9％ (23/48) ; the stable disease (SD) rate was 4.2％(2/48) ; and the local tumor control rate was 89.6％.Most of the patients had grade 1 to 2 acute side effects and grade 0 to 1 late side-effects.No grade 4 acute and late toxicity was observed.1,2,4-year survival rates were 93.8％,79.2％ and 64.5％,respectively.The DVH analysis showed that IMRT improved the total dose and dose per-fraction to the target volume with considerable dose reduction of the normal structures at the same time.Conclusions PF chronomodulated chemotherapy plus concurrent intensity-modulated radiotherapy for NPC could improve therapeutic effects with satisfactory tolerance of the side effects.

Objective To explore the diagnostic values of dual energy lung perfusion in the diagnosis of pulmonary embolism by using dual-source CT (DSCT). Methods Thirty patients with clinically suspected pulmonary embolism underwent dual-energy scanning with dual-source CT. The scanned data were integrated into three groups including 140, 80 kV and coefficient of 0.3. According to the CT pulmonary angiography (CTPA) of the fusion data, the patients were divided into pulmonary embolism group and normal group. The thin-slice reconstruction of data was analyzed using dual-energy perfusion imaging analysis software. The lung field was divided into upper, middle and lower part to make quantitative analysis of lung tissue perfusion. Paired t-tests were used in the normal patients to compare bilateral lungs, and independent samples t-tests were applied to compare the embolism group and normal group, while minimum intensity projection images (MinIP) were utilized in the assessment of lung ventilation. Results Dual energy CT showed symmetrical homogeneous perfusion in 16 normal cases, without significant perfusion defects. Quantitative analysis showed that left and right lung perfusion were (27 ± 7) and (28 ± 8 ) HU respectively, and no significant difference was found between the two sides ( t=-1.73, P ＞0.05 ).Perfusion of the left upper, middle and lower lung was ( 23 ± 6), (24 ± 6), and (28 ± 8) HU respectively, while the perfusion of right upper, middle and lower lung was (26 ±8), (27 ±8), and (28 ±9) HU respectively, showing no statistical significant difference between the two sides (t=-1.91, -1.96,-1.73 ,P＞0.05 ). Angiography of pulmonary embolism group(14 cases)showed filling defects in the pulmonary trunk, segments and sub-segments. Pulmonary perfusion imaging showed low perfusion or defectsin lung field that dominated by embolic vessels. Quantitative analysis showed that the perfusion of the whole lung and the middle and lower lung were (22 ±5), (22 ±8), and (21 ±8) HU in the embolism group,which were significantly different from the normal group (t=-2. 10, -2.32, -2.63, P＜0.05).Minimum intensity projection images showed a good consistency of abnormal ventilation zone area and perfusion abnormalities. Conclusions Pulmonary perfusion status, especially pulmonary embolism, can be analyzed by dual energy CT scanning. It helps to early discover and precisely locate the embolism.
