Squalene synthase (SQS) is a key enzyme in plant terpenoid biosynthetic pathway. This study focused on cloning and analysis of Huperzia serrata SQS (HsSQS1) gene. After searching the transcriptome dataset of H serrata, one unique sequence encoding SQS was discovered. The primers were designed according to the transcript sequence of HsSQS1 from the H. serrata transcriptome dataset. The open reading frame of HsSQS1 was cloned using RT-PCR strategy. The bioinformatic analysis of this gene and its corresponding protein were performed. The cDNA (named as HsSQS1) contains a 1263 bp open reading frame and encodes a predicted protein of 420 amino acids. The GenBank accession number for this gene is JQ004938. HsSQS1 contains two transmembrane regions, without signal peptide. The conserved domain of squalene synthase was presented in HsSQS1. HsSQS1 was more abundant in H. serrata root than in leaf and stem. This study cloned and analyzed squalene synthase gene from H. serrata for the first time. The result will provide a foundation for exploring the mechanism ofterpenoid biosynthesis in H. serrata plants.

Contributions of Xin'an medical school and physicians to acupuncture theory were introduced in the article. Academic theories or characteristics of several physicians of Xin'an school such as YANG Xuan-cao, WU Kun, WANG Ji, WU Yi-ding, ZHENG Mei-jian and XU Chun-fu, et al were sorted out. Contributions of inheriting and illustrations on acupuncture theory were analyzed so as to expound its significance and value on modern acupucture clinic.

The purpose of the present study was to explore the seizure-induced changes in Bad (Bcl-2-associated death protein), 14-3-3, phosphoBad, Bcl-2 and Bcl-XL expression in the rat model of focal limbic seizure. Unilateral intra-amygdaloid injection of kainic acid (KA) was made to induce seizure. Electroencephalogram (EEG) and regional cerebral flow (r-CBF) were monitored continuously. Diazepam (30 mg/kg) was administered to terminate the seizure. The apoptotic and surviving neurons in the hippocampus were observed by terminal deoxynucleotidyl transferrase-mediated dUTP nick end labeling (TUNEL) and cresyl violet staining, the expression of Bad, 14-3-3, phosphoBad, Bcl-2 and Bcl-XL were detected with immunofluorescence, Western blot and immunoprecipitation. The results showed that TUNEL-positive neurons appeared at 8 h and reached maximum at 24 h following seizure cessation within the ipsilateral CA3 subfield of the hippocampus. Seizure induced the dephosphorylation of Bad and the dissociation of Bad from its chaperone protein 14-3-3 and subsequent dimerization of Bad with Bcl-XL. The expression of phosphoBad decreased and Bcl-2 increased. There was little change in r-CBF after the seizure. These results suggest that seizure leads to a dephosphorylation of Bad and an upregulation of Bcl-2. Dephosphorylation of Bad may be injurious while the upregulation of Bcl-2 may be protective to the brain damage induced by seizures, but not related with r-CBF.

Objective To evaluate the safety and effcacy of intracomnary autologous bone marrow mononuclear cells(BM-MNCs)transplantation in patients with dilated cardiomyopathy(DCM).Methods On top of standard therapy,DCM patients received BM-MNCs transplantation(n=71)or saline injection (n=187).The baseline clinical characteristics of two groups were comparable.Data on echocardiography,Holter,six-minute-walk test,cardiac SPECT and annual hospital days were obrained in all patients at baseline,1,3,6,12 and 24 months after transplantation.Results Six-minute-walk distance was significantly longer at one month[(345±76)m vs. (286±104)m,P<0.05]and thereafter(all P<0.05)in BM-MNCs group compared with saline group.Left ventricular ejection fraction(LVEF)at one month in BM-MNCs group was significantly higher compared with saline group[(41.5±9.4)%vs.(37.3± 6.6)%,P<0.05]and with pre-transplantation value[(41.5±9.4)%vs.(32.4±8.5)%,P<0.05] while LVEF was similar at 24 months after transplantation between the two groups[(43.6±6.3)%vs.(43.2±6.0)%.P>0.05 ].Three months after transplantation,the number of ischemic segments of BM-MNCs group wag significantly reduced compared with that of saline group(2.0±1.0 vs.3.1 ±1.4,P<0.05)and with baseline(2.0±1.0 vs.3.1±1.2,P<0.05)while the number of necrotic segments were similar in both groups during the follow-up.There were no significant difference in survival between two groups during 2 years follow·up(95.4%vs.94.9%,P>0.05)but the aflnual hospitalization days of BM-MNCs group was significantly lower than that of saline group[(23.6±13.4)d vs.(33.0±14.0)d,P>0.05].Conclusions Intracoronary transplantation of autologous BM.MNCs was safe and could increase LVEF and the six-minute-walk distance and reduce hospitalization days for patients witIl dilated cardiomyopathy.

Objective To investigate the effect Angiontensin(1-7) [Ang(1-7)] on left ventricular dysfunction and myocardial apoptosis on rat model of adriamycin-induced dilated cardiomyopthy ( ADR-DCM ).Methods Weight-matched adult male Wistar rats were randomly divided into 3 groups:( 1 )the ADR-DCM group (n =25 ),in which 2.5 mg/kg of ADR was weekly intravenously injected for 10 weeks.( 2 ) Ang ( 1-7 ) group ( n =25 ),in which ADR rats were simultaneously treated with angiotensin-(1-7) (24 μg · kg-1 · h-1,ip.) for 12 weeks.(3) normal control group (n =10).Hemodynamics and echocardiography examination were performed at 12 weeks.The malondialdehyde (MDA) was measured by TBA methods.The plasma concentration of Ang Ⅱ was determined by immunoradiometric assay.The pathological change was analyzed by histological hematoxylin-eosin staining.Myocardial apoptosis was assessed by TUNEL method.The protein expression of pro-apoptotic protein caspase-3,Bax and antiapoptotic protein Bcl-xl in cardiomyocytes were detected by Western blot.Results Mortality was significantly lower in Ang(1-7) group than in ADR-DCM group (16％ vs.40％,P ＜0.01 ).Compared to the control group,left ventricular end-diastolic diameter ( LVEDD),left ventricular end systolic diameter (LVESD) and left ventricular end-diastolic pressure (LVEDP) were significantly increased in ADR-DCM group ( all P ＜ 0.01 ) while fractional shorting ( FS), + dp/dtmax and - dp/dtmax were significantly reduced in ADR-DCM group ( all P ＜0.01 ).LVEDD,LVESD and LVEDP were significantly reduced while FS,+ dp/dtmax and -dp/dtmax were significantly higher in Ang( 1-7 ) group compared to the ADR-DCM group,but still higher than the control group ( all P ＜ 0.01 ).The concentrations of Ang Ⅱ and MDA were higher in the ADR-DCM group than in the control group ( P ＜ 0.01 ),which were significantly reduced by Ang(1-7) treatment (P ＜ 0.01 ).The TUNEL-positive cells and apoptosis index,the expression of proapoptotic protein caspase-3 and Bax were significantly higher while the expression of anti-apoptotic protein Bcl-xl was significantly lower in the ADR-DCM group than in the control group (all P ＜ 0.01 ) which could all be partially reversed by Ang(1-7) treatment ( all P ＜ 0.01 ).Conclusion Ang (1-7) could significantly attenuate left ventricular dysfunction and myocardial apoptosis in this model by downregulating pro-apoptotic protein caspase-3 and Bax and upregulating anti-apoptotic protein Bcl-xl expression.
