ObjectiveTo discuss the clinical features, diagnosis and treatment of mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) syndrome in children.Methods The clinical features and treatment process of two children with MELAS were retrospectively analyzed.ResultsThe main clinical features of MELAS were stroke-like epi-sodes, seizure, visual anomaly and lactic acidosis. Cephalic MRI ifndings performed during episode periods were in accord with the typical radiographic features of MELAS. Gene testing on the two children and their mothers showed the point mutation of A3243G in mitochondrial genome. The symptoms were improved signiifcantly after energy supply and corticosteroid treatment. Conclusions MELAS syndrome is easy to be misdiagnosed due to the varied clinical features. The diagnosis depends on the musclebiopsy and gene testing. Corticosteroid therapy is effective for MELAS syndrome.

Objective To investigate the risk factors for nosocomial pulmonary fungal infection(PFI) in COPD patients.Methods The data of 44 cases of nosocomial PFI were analyzed from Jan 2000 to Jun 2003 in Department of Pulmonary Medicine,the First Hospital of Chongqing Medical University.44 cases of COPD patients were randomized as control.Results According to univariate analysis ,the risk factors associated with nosocomial pulmonary fungal infection include those of long-term use of broad-spectrum antibiotics,long-term use of adrenocortical steroid,diabetes mellitus,type Ⅱ respiratory failure,mechanical ventilation and hypoalbuminemia.But according to multivariate logistic regression analysis long-term use of broad-spectrum antibiotics,hypoalbuminemia,mechanical ventilation diabetes mellitus were risk factors.Conclusion Long-term use of broad-spectrum antibiotics,hypoalbuminemia,mechanical ventilation and diabetes mellitus are independent risk factors for nosocomial pulmonary fungal infection in COPD patients.

This article carefully presented the theoretical origin, clinical applications, operation and cautions of turtle-like moxibustion (direct moxibustion in nature, manifested by wheat-sized moxibustion), for promoting this method in clinic.

Objective To observe the clinical effect of inhibition about gallstone stone after extracorporeal shock wave by Liver gallstones sheet. Methods 60 patients diagnosed gallstone stone from July 2015 to November 2016, randomly divided into treatment group and control group. he treatment group received oral treatment of liver gallstones sheet, control group without special treatment, patients were followed up and recorded gallbladder wall thickness, gallbladder function and gallstone patients were relapse situation, using statistical methods to analyze data. Results After one year observation of patients gallbladder wall thickness, gallbladder function scores were (2.79±0.34,57.70±4.80) than the control group (3.14±0.39,53.13±5.01), and the differences were statistically significant (P<0.05). After one year observation group gallstone recurrence rate was 10.0%, far lower than the control group, 43.3%, and the difference was statistically significant (P<0.05). Conclusion It is worthy of further research and application and it has a good clinical results for the liver gallstones sheet after extracorporeal shock wave lithotripsy inhibition of gallstone stone.

Objective　 To study the effect of basic fibroblast growth factor (bFGF) on proliferating of rabbit lens epithelial cells(RLECs).Methods　The second and three generations of RLECs were exposed to different concentrations of bFGF, and the proliferation characteristics of the cells were measured with methyl thiazolyl tetrazolium (MTT) assay. The ultrastructure of cell were observed with transmission electron microscope (TEM).The changs of cells cycles were observed with flow cytometer (FCM).Results　 After the treatment of bFGF, RLECs showed the marked proliferation , especially in 10μg*L-1 of bFGF . TEM result showed that the cells were more active with bFGF, FCM result showed that the S phase cell obviously increased.Conclusion　bFGF is an important factor that can promote proliferation of RLECs.

A new method for the determination of peptide antibiotics in sediment from aquaculture environment by high performance liquid chromatography-tandem mass spectrometry was developed. The target analytes in sediments were ultrasonically extracted twice with citrate buffer solution and methol mixture (3∶ 4, V/ V), followed by complexation with 0. 5 g of Na2 EDTA, purification with 5 mL of methyl isobutyl ketone, and clean-up with HLB-SPE column. The analytes were separated on a MGII C18 column by gradient elution with 0. 1% formaic acid-0. 1% formaic acid acetonitrile as mobile phase, detected in multiple reaction monitoring (MRM) with electrospray ionization (ESI) under positive ion mode, and quantified by external standard method. The calibration curves were linear (R2 >0. 999) over a concentration range of 10 -10000μg / L for colistin and bacitracin and 4-4000 μg / L for virginiamycin M1 . The limits of detection (S / N = 3) were 5 μg / kg for colistin and bacitracin and 2 μg / kg for virginiamycin M1 . The limits of quantification (S / N=10) was 10 μg / kg for colistin and bacitracin and 4 μg / kg for virginiamycin M1 . At three spiked levels, the recoveries ranged from 79. 7% to 91. 6% (RSD=1. 9% -10. 8% ), showing high sensitivity, good reproducibility and wide applicability.

Objective To understand the correlation between operating room nurses′cognition of patient safety culture and hospitals responsibility,so as to provide basis to establish patient safety measures. Methods A total of 98 operating room nurses participating the meeting were investigated by convenience sampling method with Nurse′s Organizational Climate Scale and Patient Safety Culture Assessment Scale. Results The mean score of nurses′ cognition of patient safety culture was 3.58 ± 0.30,which showed a high level. The mean score of operating room nurses′perception of psychological contract was 2.17 ± 0.58,which was below the middle level. There was a negative correlation between nurses′cognition of patient safety culture and psychological contract (P<0.05). Conclusions Hospitals responsibility need to improve urgently. Nursing administrators should improve resource guarantee, management support and team behavior,in order to promote positive nurses′consciousness and behavior of patient safety and ensure the safety of patients .

Objective:To perfect and improve the quality standard of Malloti Apeltae Radix. Methods:Microscopic identification was used to identify the transverse section and the powder. The water-soluble and the fat-soluble components were identified by TLC. Rutin was used as the reference in the characteristic chromatogram established by HPLC to determine the relative retention time and rel-ative peak area of each characteristic absorption band. A SPOLAR C18 chromatographic column ( 250 mm × 4. 6 mm,5μm) was used with acetonitrile-0. 4% phosphate solution as the mobile phase with gradient elution, the detection wavelength was set at 328 nm, the flow rate was 1. 0 ml·min-1, and the temperature was 35℃. Results: The microscopic characteristics were obvious. The spots of TLC were round and clear with good repeatability. Five characteristic absorption bands were shown in the fingerprints with the relative retention time within ± 5% of reference value of rutin, and the relative area of peak 3 and peak 4 was not lower than 0. 23 and 0. 66, respectively. Conclusion:The method is convenient, fast and repeatable, and the result is accurate and reliable, which can be used to control the quality of Malloti Apeltae Radix effectively, and as the main index of the quality standard.

Currently,China is confronted with the situation of high quality papers and low impact journals.Quality and quantity of English science,technology and medical(STM) journals in our country can not meet the publishing demand of scientific research papers,which becomes the inner boost of developing English STM journals.Along with the implementation of Project for Enhancing International Impact of China STM Journals,a growing number of STM journals launched international cooperation in journal publishing.This paper introduced Genes & Diseases' strategy of launching and managing English journals in cooperation with foreign publisher.Genes & Diseases strictly follows international publishing practice.The editorial office of Genes & Diseases fully aroused the enthusiasm of editors,editorial board members and the editor-in-chief to solicit manuscripts.Meanwhile,the office of Genes & Diseases took advantages of website,social media,Emails,meeting and academic activity,etc to promote the journals.All these experiences can be used as references for those intended or already started to lunch English STM journal.
