Objective: To verify that COX-2 promoter can drive its downstream genes specifically in COX-2-positive o-varian cancer cells; Moreover, comparing with CMV promoter, analyze the transcript efficiency of COX-2 promoter. Methods: Contacting the recombinant plasmids named COX-2-BAX and CMV-Luc. After transient transfection liposome-mediated with the plasmids COX-2-Luc and CMV-Luc, respectively, the expression of Luciferase reporter gene was measured in COX-2-positive ovarian cancer cell line-SKOV3 and COX-2-negative colon cancer cell line-SW480. SKOV-3 and SW480 were transfected with COX-2-BAX and CMV-BAX in the same way, respectively. The apoptosis rates were measured through flow cytometry. Results: The recombinant plasmids named COX-2-BAX and CMV-Luc were constructed successfully. The expression efficiency of reporter gene was 1554 ? 86. 5 in SKOV3 and 53. 7 ? 10.9 in SW480 after 24 hours transfected with phPES2, 9851. 7 ? 129. 5 in SKOV3 and 8831. 0 ? 167. 3 in SW480 after 24 hours transfected with CMV-Luc in the same way. The apoptosis rate was 10.4% in SKOV3 and 3.7% in SW480 after transfected with COX-2-BAX, 21.7%in SKOV3 and 25. 6% in SW480 after 36 hours transfected with pcDNA3-BAX in the same way. Conclusions: COX-2 promoter can drive its downstream genes specifically in COX-2-positive ovarian cancer cell lines, but its expression efficiency wasmarkedly lower than CMV promoters. With proper modification, COX-2 promoter is expected to be useful in gene therapy of ovarian cancers.

Objective To research the electrocardiogram (ECG) manifestations of common electrolyte disturbance and to discuss the accuracy of ECG diagnosis. Methods One hundred and sixty-nine hospitalized patients with hyperkalemia and 170 patients with hypokalemia were selected and the results of ECG were analyzed. Results In mild hyperkalemia patients (serum potassium concentration 5.5- 6.5 mmol/L), the ECG abnormal rate was 91.4% (64/70). In mild hypokalemia patients (serum potassium concentration 3.0-3.5 mmol/L), the ECG abnormal rate was 56.9% (41/72). There was significant difference (P < 0.05). The greater the deviation of serum potassium concentration, the more obvious the characteristic changes of ECG. Conclusions In addition to the blood biochemical test, ECG is also a kind of check tool that can help to diagnose abnormal blood potassium.

Objective To investigate the variation patterm in activity concentration of 210Pb in atmospheric aerosol in Qindao and evaluate its internal radiation effect to human body.Methods 210Pb activity concentration of aerosol samples was measured by high purity germanium(HPGe) γ spectrometer for purpose of ascertaining its variation in aerosol in Qingdao from April 2015 to March 2016.Results 210Pb activity concentration in aerosol varied from 0.06 to 1.61 mBq/m3 and the mean of (0.70 ± 0.50) mBq/m3,slightly higher than the UNSECAR 1988 report recommended value of O.50 mBq/m3.In this study,210Pb activity concentration in aerosol was high from December 2015 to February 2016 and low from August to November.Radiation dose assessment revealed that the annual committed effective dose to adults delivered by 210Pb was 6.35 × 10-6 Sv.The monthly variation in activity concentration variation of 210Pb in atmospheric aerosol in Qingdao was similar as in Xiamen.Conclusions Activity concentration of 210Pb in atmospheric aerosols in Qingdao varied largely dependent on atmospheric environmental pollution.210Pb contributed less to the adult annual committed effective dose.However,more attention should be drawn to the long-term radiation effects to aduhs due to the 210Pb potentially deposited in lungs.

Febrile infection -related epilepsy syndrome(FIRES)is a newly named entity of epileptic encepha-lopathy in recent years.As one of the hot spots studied by domestic and foreign scholars,the etiology and pathogenesis of FIRES,which has a poor treatment and outcome,are undefined.It manifests with refractory seizures and status epilep-ticus in previously healthy school -aged children after banal febrile illness.In addition,with the negative response to currently available treatments,there are a poor prognosis and a high mortality rate in FIRES.Survivors are typically left with refractory partial epilepsy and severe cognitive impairment.Through domestic and foreign literature,this article re-views the potential pathogenesis,clinical features,treatment and prognosis of the syndrome,and provides theoretical ba-sis and new ideas for clinical diagnosis and treatment.
