According to the designed specific primers of gene fragment based on the Salvia miltiorrhiza transcriptome data, with the method of reverse transcription polymerase chain reaction (RT-PCR), this study cloned full-length cDNA sequence of 1-hydroxy-2-methyl-2-(E)-butenyl-4-diphosphate synthase gene from Salvia miltiorrhiza bge.f.alba, this sequence is named as SmHDS and its GenBank registration number is KJ746807. SmHDS, 2 529 bp long, contains an ORF of 2 229 bp, encodes 742 amino acids, including 5' UTR 170 bp and 3' UTR 130 bp. Using bioinformatics software, having made a homology analysis of the obtained sequence, we can have a conclusion that SmHDS have a close genetic relationship with HDS of Salvia miltiorrhiza. Analysis result of prokaryotic expression revealed that in Escherichia coli, SmHDS expressed target proteins which in size are comparable with the protein predicted. Meanwhile, the 4 factors which can influence the protein expression were optimized, the 4 factors are inducing temperature, inducing time, IPTG concentrations and density of inducing host bacterium (A600). The optimal expression conditions of SmHDS were 30 degrees C until the A600 is 0.6, and add IPTG to a final concentration of 0.2 mmol x L(-1), and the induction time of 20 h. It provides theoretical basis for the further study of the function of 1-hydroxy-2-methyl-2-(E)-butenyl-4-diphosphate synthase in the biosynthesis of tanshinone compounds.

Objective: To detect the changes of serum level of connective tissue growth factor (CTGF) in patients with ST-segment elevation myocardial infarction (STEMI) and to study the correlation between CTGF level and the maximal activity of creatine kinase-MB (CK-MB). Methods: Our research included 2 groups of patients: STEMI group and unstable angina (UA) group. All patients were treated in our hospital from 2013-07 to 2014-06,n=50 in each group. In STEMI group, the serum levels of CTGF were examined by ELISA at 24h, 2, 7, 14 days of onset, and in UA group, CTGF level was examined at 24h of onset. The CK-MB activity levels were measured in STEMI group at the same time points by immunosuppression method. Results: The serum level of CTGF in UA patients at 24 h of onset was (10.34 ± 2.00) ng/mL, and in STEMI patients were (16.76 ± 3.17) ng/mL at 24h, (29.87 ± 4.90) ng/mL at 2d, (45.02 ± 8.35) ng/mL at 7d and (31.61 ± 4.40) at 14d. The CTGF levels in STEMI group at different time points were all higher than UA group at 24h of onset,P<0.01. In STEMI group, the CTGF levels were increasing from 24h to 7d, then decreasing at 14d, allP<0.01. In STEMI group, the highest protein concentration of CTGF was positively related to the maximal activity of CK-MB at 7 days of onset (r=0.859,P=0.000). Conclusion: CTGF expression has been up-regulated in STEMI patients which might be related to myocardial ifbrosis. The protein level of CTGF is related to MI size, it shows certain predictive value in relevant patients.

OBJECTIVE: To investigate the lexical tone perception and quality of life of Nurotron cochlear implant users. METHOD: Forty-nine adult cochlear implant users participated in this study. Mandarin tone identification test developed by Beijing Institute of Otolaryngology was used to evaluate the tone perception. Nijmegen cochlear im plantation questionnaire (NCIQ) was administered to quantify the quality of life. RESULT: (1) The average scores of tone perception in quiet was 67.26%. The tone perception rates under quiet condition for all cochlear implant recipients were higher than the opportunity level. (2) The average scores of tone perception under noisy condition was 51.92%. Exc ept for two recipients, the tone perception rates under noise condition for the rest recipients were better than chance. (3) The confusion patterns of tone recognition showed that Tone 3 was the easiest tone to perceive. (4) The postimplant scores for the total , basic sound perception, advanced sound perception, speech pro duction, self-esteem, activity and social interactions of NCIQ were 55.4, 72.4, 54.0, 63.4, 50.7, 47.3 and 44.7, respectively. CONCLUSION The Nurotron cochlear implant users had the ability for lexical tone perception and had an improvement in quality of life after cochlear implantation.

Objective To investigate the disease situation of adult carotid atherosclerosis in water-related endemic fluorosis areas in Heilongjiang province in 2008 so as to explore the relationship between water-related endemic fluorosis and incidence of carotid atherosclerosis disease. Methods A total of 266 participants over the age of 40 from four villages in Zhaozhou county with water fluoride ≥ 1.0 mg/L in a fluorosis area and 283 residents over the age of 40 from four villages in Tailai county with water fluoride ＜ 1.0 mg/L in a nonfluorosis area were investigated. A portable-type B mode color ultrasound was used to examine the left carotid artery of all participants.The carotid atherosclerosis was diagnosed and graded through the ultrasonograms. Results The prevalence rates of carotid atherosclerosis in the 4 fluorosis villages(Xinfeng, Taipingshan, Baochan and Houzheng villages) were 47.3% (35/74), 63.5%(40/63), 73.3%(33/45) and 60.7%(51/84), respectively, and in the 4 nonfluorosis villages(Hala,Qianxing, Sanjia and Ailin villages) were 32.7% (17/52), 32.9% (24/73), 39.2% (31/79) and 30.4% (24/79),respectively. The prevalence rates of carotid atherosclerosis in every villages standardized by age were 47.3% ,63.5%,73.3% ,60.7% and 34.7% ,36.3% ,43.0% ,41.3%, respectively. Statistic method used was Wilcoxon two sample test and the differences were significant(T = 26, P ＜ 0.05 ). Total carotid atherosclerosis positive rate standardized by age in the 4 fluorosis villages was significantly higher than that in the 4 nonfluorosis villages[57.5%(153/266) ,37.8% (107/283), x2 = 21.36, P ＜ 0.01 ]. After standardized by age, the severity of carotid atherosclerosis was significantly different between fluorosis villages and nonfluorosis villages (x2 = 36.15, P ＜ 0.01 ). Conclusion The prevalence rate of carotid atherosclerosis in endemic fluorosis area is higher than that in nonfluorosis area.

Objective To analyze the epidemiologic characters of human plague from Rattus flavipectus plague natural foci in Yunnan Province from 1986 to 2006 and to provide references for prevention and control strategy.Methods Data were collected and analyzed on epidemic situation of human plague in the past twenty-one years.Results From 1986 to 2006,the total human plague cases from Rattus flavipectus plague natural foci in Yunnan were 507,accounted for 59.5%(507/866)of the total cases in the whole country.There were three peaks of human plague outbreak in 1990,1996 and 2000.The number of annual cases were 73,88 and 122,accounting for 97.3%(73/75),89.8%(88/98),48.0%(122/254)of the total cases in the whole country respectively.The epidemic areas were mainly located in the west,southwest and southeast pans of Yunnan,but the number of cases changed with year in different prefectures(or cities).Seasonal pattern analyses revealed that the epidemic could occur in whole year,with a peak period through July to November,especially September.There were different prevalence of plague cases in age and professions,which related to the chance of contact with infected animals and infectious fleas.All human plague cases were primary bubonic plague.Conclusions The results suggested that there were clear epidemic characteristics for human plague for Rattus flavipectus plague natural foci in Yunnan.In order to control human plague effectively,it was necessary to reinforce surveillance and warning system to diminish the outbreak of human plague.

High resolution melting (HRM), an important technology for genotyping and mutation scanning, has broad prospects in the authentification of traditional Chinese medicine. This paper selected universal trnH-psbA primers and used HRM to establish a new methods for identification of Akebia herbs. PCR was conduct at the annealing temperature of 58 degrees C and 35 cycles. The range of the DNA template concentration, the primer concentration and the Mg2+ ion concentration were further analyzed. The results showed the Tm values of Caulis Akebiae was (81.84 ± 0.16), (85.28 ± 0.16) degrees C and Caulis Clematidis Armandii was (83.22 ± 0.19) degrees C and Caulis Aristolochiae manshuriensis was (81.67 ± 0.14) degrees C, (84.24 ± 0.10) degrees C with 5-125 mg - L-' DNA template, 0.4 μmol x L(-1) primer, 2.0 mmol x L(-1) Mg2+. This method can achieve the authentification of Akebia herbs and is simple, fast, high-throughput, visual.
