ABSTRACT
Objective To investigate the effect of miR-107 on the function of human non-small cell lung cancer cell line A549 and its possible target genes.Methods The experiment was divided into the liposome+miR-107 mimics overexpression group(OV-miR-107 group),liposome+miR-107 inhibiting mimics downregulation group(KD-miR-107 group)and liposome+ negative control mimics group(NC group).The cell transfections of siRNA were siRNA-1,siRNA-2 and siRNA-3 respectively.The cellular prolifer-ation capacity was detected by MTT assay.The cellular cycle was detected by flow cytometry.The dual luciferase reporter gene as-say was performed to detect the downstream target gene of miR-107.The real time quantitative reverse transcription PCR and Western blot were respectively employed to examine mRNA and protein expression levels of downstream target gene.Results miR-107 inhibited the proliferation of A549 cells in a time-and dose-dependent manner(P<0.05).miR-107 arrested more A549 cells at the G0G1phase,and the proportions of S phase and G2M phase were decreased(P<0.05).miR-107 combinded with the 246 bp-253 bp of CCNE1 3′-untranslated region,and decreased mRNA and protein expression of CCNE1(P<0.05);after down-regulating CC-NE1 in A549 cells,siRNA-2 inhibited cellular proliferation(P<0.05)and blocked the cells to stay at G0G1phase(P<0.05).Con-clusion miR-107 inhibits the proliferation of human non-small cell lung cancer cell line A549 and regulates the cellular cycle by tar-geting CCNE1.
ABSTRACT
OBJECTIVE:To improve the electronic prescription prior-review mode and increase the rate of qualified prescrip-tions. METHODS:The electronic prescription prior-review mode of our hospital was established by setting up outpatient and emer-gency electronic prescription review team,review evidence and enforcement measures. Aimed at these problems as low review effi-ciency at initial stage,non-unified standards and untimely feedback,quality control circle and internet tools WeChat were used to improve the mode and evaluate its effects. RESULTS:The electronic prescription prior-review mode of our hospital was improved by optimizing system settings,unifying review standard,one-to-one feedback and communication with WeChat public platform, etc. Average time of prescription prior-review had reduced from 50 s to 30.58 s;the rate of qualified prescriptions had increased from 86.77% to 95.30%;prescription review efficiency and the rate of qualified prescriptions had been improved significantly. CONCLUSIONS:The implementation and continuous improvement of electronic prescription prior-review mode can reduce the rate of unqualified prescriptions and promote rational drug use in outpatient and emergency department.
ABSTRACT
Objective To investigate the clinical characteristics of a clustering infection caused by human adenovirus-B type 7 (HAdV-B7) which occurred in one military camp located at the southeastern coastal region in January 2014.Methods All clinical characteristics of the 70 patients were collected for analysis,including clinical symptoms and signs,chest computer tomography (CT) scans and laboratory results.Throat swabs were collected and real time polymerase chain reaction (RT-PCR) was performed to detect viral nucleotide.Results The prominent symptoms of these patients with HAdV-B7 infection included fever (100.0％,70/70),cough (82.9％,58/70),productive cough (72.9％,51/70) and sore throat (61.4％,43/70).All patients showed posterior pharyngeal wall linear congestion with ovoid follicle.Fifty-four (77.1 ％) patients had enlarged tonsils and 46 (65.7 ％) patients had tonsils covered by white secretions.Fifty-eight (82.9 ％) patients had pharyngeal follicular hyperplasia.Fifty-one (72.9 ％) patients had abnormalities on chest radiograph,including lung-marking fuzzy,pulmonary interstitial inflammation and parenchymal serous exudation.Of the 54 throat swabs from patients,34(63.0％) were identified as HAdV-B7.All patients were cured.Conclusions The clinical features of patients with HAdV-B7 infection are different from other viral infection.HAdV-B7 is easy to cause clustering infection in particular populations.Early detection and early intervention are needed to avoid exacerbation and transmission.
ABSTRACT
Objective:To investigate the role of clinical pharmacists in the process of chemotherapy for a patient with intracranial glioma. Methods:Usage and dosage of antitumor drugs, drug interactions, adverse drug reactions and medication education after dis-charged as the breakthrough points, clinical pharmacists and clinicians explored options for the patient treatment and adjusted the medi-cation timely according to the condition. Results:There were no serious adverse drug reactions in the adjusted therapeutic regimen and the treatment results of the patient were satisfactory. Conclusion:Clinical pharmacists provide pharmaceutical care can play an impor-tant role in improving the safety and effectiveness of drug use.
ABSTRACT
Objective To evaluate the clinical application and safety of CT-guided transthoracic cutting needle lung biopsy in diagnosing diffuse lung diseases. Methods By using automatic biopsy gun (14 & 16 gauge), CT-guided transthoracic cutting needle lung biopsy was performed in 29 cases with diffuse lung diseases. The samples obtained were sent for pathological and immunohistochemical examination. The sampling successful rate, the diagnostic accuracy and the occurrence of complications were analyzed. Results Technical success rate was 100%, and large size of sample enough for pathological and immunohistochemical examination was obtained in all 29 cases. Definite pathological diagnosis could be made in 25 cases, with the positive diagnostic rate of 82.8%. The main complications included pneumothorax and pulmonary hemorrhage. The symptoms in most cases were not severe and disappeared within one week after the treatment. Conclusion For the diagnosis of diffuse lung diseases, CT-guided transthoracic cutting needle lung biopsy is a safe, easy, effective and reliable method with high successful rate, high diagnostic value and fewer complications, in these respects this technique is superior to transbronchial lung biopsy, open lung biopsy and video-assisted thoracoscopic lung biopsy. Therefore, this technique should be popularized in clinical practice.
