OBJECTIVE:To study the enterococcal distribution in clinical samples and their drug resistance to commonly use antibiotic and provide the guidance for rational administration.METHODS : Adopting paper diffusion method to observe the drug resistance of enterococci isolated from clinical samples in our hospital and analyzing their distribution in the samples.RESULTS :Enterococcus faecalis accounts for 44.1% in 227 strains and Enterococcus faecium accounts for 37.9%,the other kinds of enterococci were rare.There was no statistical difference between drug resistance of Enterococcus faecium and that of enterococcus faecalis. Vancomycin was the most potent antimicrobial.Penicillin,ampicillin,and nitrofurantion showed good antibacterial activity against enterococcus faecalis. Enterococcus faecium displayed high-level resistance against antibiotics in addition to glycopeptides.CONCLUSION:Doctor should pay attention to the drug resistance about clinically common pathogenic bacterium. Continual surveillance of resistance rate of enterococcus is important to direct the treatment of enterococcus infections.

China Pharmacy 1991;0(06):-
OBJECTIVE:To provide the reference for the set-up of precautions against flu pandemic in China.METHO_DS:RNA of influenza viruses isolated from flu children in flu seasons between 2003 and 2005 in Beijing was extracted and amplification of M2 gene fragments associated with ion channel were performed by one step reverse transcription–polymerase chain reaction(RT-PCR).The sequencing of amino acid was determined,and its bioinformation was analyzed with software,then the positions of amino acid for resistance to amantadine were detected.RESULTS:20 of 31 isolated strains were resistant to amantadine,the percentage of which was 66.7%.CONCLUSION:The monitoring of drug resistance to flu viruses should be strengthened in China.
3.Determination of baicalin, rhein and berberine in Yiqing Capsule by HPLC
Chinese Traditional Patent Medicine 1992;0(02):-
AIM: To determine the contents of baicalin, berberine, rhein in Yiqing Capsule(Radix et Rhizoma Rhei, Radix Scutellariae, Rhizoma Coptidis) by HPLC. METHODS: The HPLC system consisted of Kromasil C 18 column (150 mm?4.6 mm, 5 ?m), 0.02 mol?L -1 phosphoric acid (TEA adjusted to pH=6.82)-acetonitrile(40∶11) mixture as mobile phase, detection wavelength at 254 nm, flow rate of 1.0 mL?min -1. RESULTS: The calibration curves of three ingredients were linear within the range of 3.666-73.32 mg?L -1(r=0.9998, baicalin), 0.3112-15.56 mg?L -1(r=0.9998, rhein), 1.221-50.04 mg?L -1(r=0.9999,berberine), respectively. The average recovery of baicalin is 102.3%(RSD=2.5%), berberine for 101.8%(RSD=1.8%), and rhein for 98.3%(RSD=2.9%). CONCLUSIONS: The method is rapid, sensitive and accurate.
4.Conventional MRI,DWI characteristics and pathological basis of angiomatous meningioma
Journal of Practical Radiology 2014;(6):911-913,922
Objective To explore the conventional MRI,diffusion-weighted imaging (DWI)characteristics and the pathological basis of angiomatous meningioma.Methods The conventional MRI,DWI and pathological manifestations of 7 cases with angioma-tous meningioma confirmed by surgery and pathology were analyzed retrospectively.The apparent diffusion coefficient (ADC)value of the tumors and contralateral normal brain parenchyma were measured and compared with each other.Results Among the 7 ca-ses,5 cases were in the convexity of brain (4 cases in the frontal part and 1 case in the parietal part),and 2 cases in the parasella. 6 cases showed hypointense on T1 WI and hyperintense on T2 WI,and 1 case showed isointense on both T1 WI and T2 WI.The necro-sis within the tumor was seen in 2 cases.The flowing void phenomenon was seen in 6 cases.The significant peritumoral edema was seen in 5 cases on FLAIR.Significant enhancement on contrast-enhanced T1 WI was seen in all the cases.The average ADC value of the tumors (1.35×10 -3 mm2/s)was significently higher than that of the contralateral normal parenchyma (0.92 × 10 -3 mm2/s) (t=7.21,P <0.01).Mature vessel component was seen on pathological section in all the cases.For immunohistochemically analy-sis,the expression of vimentin (Vim)was positive in 6 cases and scattered positive in 1 case.The expression of epithelial membrane antigen (EMA)was positive in all the cases.Conclusion The MRI features of angiomatous meningioma are closely correlated with rich blood vessels.The ADC value of the tumor is higher than that of the contralateral parenchyma,which is helpful for the diagno-sis.

6.Next generation sequencing technologies in clinical virological detection
Chinese Journal of Laboratory Medicine 2017;40(5):338-340
Next generation sequencing technologies,providing high speed and throughput that contribute greatly to DNA sequencing,have many applications in clinical virology,including identification of novel or unsuspected viruses,evaluation of human viromes,investigation of viral genetic diversity and evolution,monitoring of antiviral drug resistance,and analysis of virus-host interaction.Meanwhile,due to the complexity in bioinformatics data processing and lack of quality management standards,further efforts and explorations need to be put in the application and quality management of NGS in clinical laboratory.
7.Valsartan Improves Endothelial Function in Essential Hypertension Patients
Chinese Journal of Hypertension 2006;0(08):-
Objective To evaluate the effect of valsartan on endothelial function in patients with essential hypertension. Methods Thirty six patients of essential hypertension recieved valsartan(80 mg/d) for 8 weeks. After treatment, serum NO, SOD and MDA were measured using chemically colorimetric method. Brachial artery endothelium-dependent dilation function(FMD) was determined by high resolution ultrasonography. Twenty six health adults served as controls. Results Compared with the control, FMD was significantly decreased (P
