The inheritance of famous old traditional Chinese medicine (TCM) doctors plays an essential role in the fields of TCM research. Qualitative interviews allow for subjectivity and individuality within clinical experience as well as academic ideas of doctors, making it a potential appropriate research method for inheritance of famous old TCM doctors. We summarized current situations of inheritance research on famous old TCM doctors, and then discussed the feasibility of applying qualitative interviews in inheritance of famous old TCM doctors. By combining our experience in research on inheritance of famous old TCM doctors, we gave some advice on study design, interview implementation, data transcription and analyses , and report writing, providing a reference for further relevant research.

Objective: To study the optimum process of Shanxiangyuan (Turnipia argute) Baccal Tablet. Methods: Inhibition effect on bacteria is observed and concentration of ursolic acid is determined for choosing the optimum process of Shangxiangyuan Baccal Tablet. Results: The optimum process is that the crude powder of the leaves of Turnipia arguta is soaked by 70% alchol for 72 hours and percolated. The liquid is concentrated to the density of 1.20. Sugar powder and dextin are as excipients. The granules are made by the way of spray drying. Conclusion: The process is reasonable and favorable for industrial production.

OBJECTIVETo analyze the change in drug resistance of Staphylococcus aureus (SAU) in the PLA general hospital from January 2008 to December 2012, and to provide solid evidence to support the rational use of antibiotics for clinical applications.

METHODSThe SAU strains isolated from clinical samples in the hospital were collected and subjected to the Kirby-Bauer disk diffusion test. The results were assessed based on the 2002 American National Committee for Clinical Laboratory Standards (NCCLS) guidelines.

RESULTSSAU strains were mainly isolated from sputum, urine, blood and wound excreta and distributed in penology, neurology wards, orthopedics and surgery ICU wards. Except for glycopeptide drugs, methicillin-resistant Staphylococcus aureus (MRSA) had a higher drug resistance rate than those of the other drugs and had significantly more resistance than methicillin-sensitive Staphylococcus aureus (MSSA) (P < 0.05). In the dynamic observation of drug resistance, we discovered a gradual increase in drug resistance to fourteen test drugs during the last five years.

CONCLUSIONDrug resistance rate of SAU stayed at a higher level over the last five years; moreover, the detection ratio of MRSA keeps rising year by year. It is crucial for physicians to use antibiotics rationally and monitor the change in drug resistance in a dynamic way.

[ ABSTRACT] AIM: To investigate the regulatory mechanism of histone acetylation on cardiac hypertrophy in -duced by phenylephrine , and to provide a new idea for preventing and curing hypertrophic cardiomyopathy .METHODS:Phenylephrine was given by continuous subcutaneous injection for modeling cardiac hypertrophy in C 57BL/6 mice.The le-vel of histone H3 lysine 27 acetylation (H3K27ac) in the promoter of cardiac nuclear transcription factor GATA4 and the mRNA expression of GATA4 were identified by chromatin immunoprecipitation (ChIP) and real-time PCR, respectively. Meanwhile, the protein expression of histone H3K27ac, atrial natriuretic peptide (ANP) and α-myosin heavy chain (α-MHC) was determined by Western blot .Cardiac hypertrophy in the mice was observed by HE staining and echocardio-graphy.RESULTS:The results of Western blot showed that the level of histone H 3K27ac in phenylephrine group was sig-nificantly increased compared with normal saline group (P<0.05), and ChIP-qPCR data showed that the level of histone H3K27ac in the promoter of GATA4 was increased significantly in the same samples (P<0.05).The expression levels of GATA4 mRNA and ANP protein in phenylephrine group were apparently increased compared with normal saline group ( P<0.05).However, histone acetylase inhibitor anacardic acid attenuated histone H 3K27 hyperacetylation induced by pheny-lephrine, and downregulated the over-expression of GATA4 and ANP in the heart of the mice (P<0.05).HE staining and echocardiography data showed that phenylephrine apparently increased left ventricular posterior wall thickness and de -creased left ventricular end-systolic diameter and left ventricular end-diastolic diameter , while anacardic acid also reversed these indexes that mentioned above and attenuated cardiac hypertrophy induced by phenylephrine in the mice .CONCLU-SION:Histone acetylation modification imbalance is involved in cardiac hypertrophy induced by phenylephrine , and the histone acetylase inhibitor anacardic acid decreases histone hyperacetylation induced by phenylephrine and attenuates car -diac hypertrophy in the mice .

Objective To investigate the effects of H3K9ac hyperacetylation mediated by histone acetylases on the overexpression of MEF2C in the hearts of fetal mice exposed to alcohol during pregnancy,and provide new interven-tion targets for prevention and treatment of cardiac dysplasia caused by alcohol exposure.Methods C57BL/6 mice were divided into 5 groups randomly,blank control group,dimethylsulfoxide (DMSO)group,alcohol group,alcohol +anacardic acid group and anacardic acid group,and then the hearts of fetal mice were collected to be analyzed.Chroma-tin immunoprecipitation and Western blot were used in assaying the binding of histone acetylases and the level of H3K9ac to the promoter of MEF2C in the hearts of fetal mice.The mRNA expression of MEF2C was tested by adopting real -time PCR.Results The level of H3K9ac in the promoter of MEF2C in the hearts of fetal mice exposed to alcohol was higher than that in the hearts of fetal mice exposed to saline (1 .30 ±0.1 9 vs 0.45 ±0.01 ),there was statistically significant difference (P <0.05),while the binding of E1 A -binding protein (p300),p300 /cyclic adenosine mono-phosphate response element binding protein -associated factor (PCAF)and steroid receptor coactivator -1 (SRC1 )to the promoter of MEF2C were abnormally elevated in the hearts of fetal mice treated by alcohol (1 .68 ±0.08 vs 0.82 ± 0.08,1 .08 ±0.05 vs 0.42 ±0.02,1 .1 8 ±0.05 vs 0.39 ±0.08),and there were statistically significant differences (all P <0.05).The expression of MEF2C mRNA in alcohol group was higher than that in blank control group (1 .36 ± 0.1 2 vs 0.29 ±0.03),there was statistically significant difference(P <0.05).However,a pan -acetylases inhibitor, anacardic acid,could decrease significantly the binding of p300 and PCAF to the promoter of MEF2C (1 .52 ±0.05 vs 0.63 ±0.09,1 .1 3 ±0.04 vs 0.45 ±0.04),and correct abnormal hyperacetylation of H3K9ac induced by alcohol (1 .58 ±0.08 vs 0.67 ±0.05),and down -regulate the over -expression of MEF2C in the hearts of fetal mice exposed to alcohol (1 .36 ±0.1 2 vs 0.41 ±0.05 ),and there were statistically significant differences (all P <0.05 ). Conclusions Hyperacetylation of H3K9ac mediated by p300 and PCAF may be a key regulatory factor in the over -expression of cardiac nuclear transcription factor MEF2C in the hearts of fetal mice exposed to alcohol during pregnan-cy.Anacardic acid can significantly attenuate the level of H3K9ac through inhibiting the binding of p300 and PCAF to the promoter of MEF2C,and down -regulate the over -expression of cardiac nuclear transcription factor MEF2C in the hearts of fetal mice.

AIM:To study the effects of FK506 binding protein 12.6(FKBP12.6) overexpression on the performance of sarcoplasmic reticulum(SR) in ventricular myocytes of rats with heart failure.METHODS:The adenovirus(Ad)-mediated gene transfer was used to overexpress FKBP12.6 in ventricular myocytes of rats with heart failure.Western blotting and reverse transcriptase-polymerase chain reaction(RT-PCR) analysis were used to reveale specific overexpression of FKBP12.6.X-rhod-1-AM was used as the Ca2+ indicator,and cells were viewed under a confocal microscope.RESULTS:Adenovirus mediated overexpression of FKBP12.6 resulted in a 5-fold increase in relative FKBP12.6 mRNA levels and a 4-fold increase in relative FKBP12.6 protein levels at 48 h after transfection compared with control.The amplitude of the fluorescence [Ca2+]i transient was significantly increased in Ad-FKBP12.6-GFP cardiomyocytes compared with Ad-GFP myocytes(peak F/F0,3.16?0.42 vs 1.43?0.38,P
