The aim of this paper is to apply Raman spectroscopy technique to develop rapid quantitative models for five kinds of Traditional Chinese Medicine containing CaCO3. In the experiment, Raman spectras of 67 batch of sample including Otolithum Sciaenae, Galaxeae Os, Ophicalcitum, Calcite, Stalactite and their mixture which had different content of CaCO3 were collected, and the quantitative models were established by using an improved siPLS to optimize the characteristic spectral bands and using the CaCO3 contents which were measured by EDTA titration method as references. Compared with the results by EDTA titration, the established quantitative model for CaCO, content showed a prediction result that the average relative deviation of the prediction results is 2. 71% and the average recovery rate was 100.46%, when the content is between 0.465 4-0.999 7, and when the characteristic spectral bands of 1 290-1 280, 730-714, 700-690, 660-650, 465-460, 455-445, 405-385 cm(-1) had been optimized. The result also showed that the model using Raman spectroscopy and based on an improved siPLS can get a rapid determination for contents of 5 kinds of Traditional Chinese Medicine containing CaCO3.

The aim of this paper is to apply near infrared spectroscopy techniques to construct a rapid identification method for 8 kinds of mineral Chinese Medicines containing carbonates. The qualitative model using clustering analysis method in OPUS software can identify accurately 8 kinds of carbonate-containing mineral Chinese medicines. The near-infrared quantitative model was established by using partial least squares method (PLS) for 7 mineral Chinese Medicines in which main component is calcium carbonate. Compared with the results by EDTA titration, the established quantitative analysis model for calcium carbonate content showed a good prediction result that when the content is between 47.61% -99.17%, the average relative deviation of the prediction result is 0.24% and the average recovery rate was 100.3%. The results also showed that the model using near infrared spectroscopy can get not only a rapid identification of the 8 mineral Chinese medicines containing carbonates, but also an accurate and reliabe content determination of calcium carbonate for the 7 mineral Chinese medicines which contain the component.

Objective Previous studies showed that hypoxia preconditioning could protect cardiac function against subsequent myo-cardial infarction injury. However, the effect of hypoxia on left ventricular after myocardial infarction is still unclear. This study therefore aims to investigate the effects of hypoxia training on left ventricular remodeling in rabbits post myocardial infarction. Methods Adult male rabbits were randomly divided into three groups: group SO (sham operated), group MI (myocardial infarc-tion only) and group MI-HT (myocardial infarction plus hypoxia training). Myocardial infarction was induced by left ventricular branch ligation. Hypoxia training was performed in a hypobaric chamber (having equivalent condition at an altitude of 4000 m, FiO214.9%) for 1 h/day, 5 days/week for four weeks. At the endpoints, vascular endothelial growth factor (VEGF) in the plasma was measured. Infarct size and capillary density were detected by histology. Left ventricular remodeling and function were as-sessed by echocardiography.Results After the 4-week experiment, compared with the group SO, plasma VEGF levels in groups MI (130.27 ± 18.58 pg/mL,P< 0.01) and MI-HT (181.93 ± 20.29 pg/mL,P< 0.01) were significantly increased. Infarct size in Group MI-HT (29.67% ± 7.73%) was deceased remarkably, while its capillary density (816.0 ± 122.2/mm2) was significantly increased. For both groups MI and MI-HT, left ventricular end-diastolic and end-systolic dimensions were increased whereas left ventricular ejection fraction was decreased. However, compared with group MI, group MI-HT diminished left ventricular end-diastolic (15.86 ± 1.09 mm,P< 0.05) and end-systolic dimensions (12.10 ± 1.20 mm,P< 0.01) significantly and im-proved left ventricular ejection fraction (54.39 ± 12.74 mm,P< 0.05).ConclusionHypoxia training may improve left ven-tricular function and reduce remodeling via angiogenesis in rabbits with MI.

The highly-pathogenic EV71 strain is the primary cause of mortality in hand-foot-and-mouth disease (HFMD) associated with neurological symptoms, for which no clinically effective drugs or vaccines exist. This study aimed to construct infectious cDNA clones of the EV71 highly-pathogenic strain and the cell-culture adapted strain using a reverse genetics approach. The genomic RNAs of EV71 parent strains were used as the templates for RT-PCR amplification, and then the PCR products that overlapped the full-length genome were connected into the pBR322 vector to produce infectious clones of pEV71 (HP) and pEV71 (CCA), respectively. The results showed that the HP strain propagated much more quickly than the CCA strain. The rescued viruses derived from the infectious clones not only maintained their consistency with their parent strains in terms of genomic sequences, but also retained their respective biological phenotypes. This research will contribute to our understanding of EV71 pathogenesis and the development of novel vaccines against HFMD.

ObjectiveTo investigate and compare the prevalence,awareness and risk factors of chronic kidney disease (CKD) between urban and rural population in Guangxi province in order to provide information for prevention and treatment of CKD.MethodsBy a stratified multistage random sampling method,18 to 74 years old residents in Guangxi province were surveyed. They wereevaluatedbyquestionnaire,urinaryalbumin/creatinineratio, hematuria (microscopic examination of centrifuged urine sediment),kidney B-mode ultrasound,and abnormal results were reviewed 3 months later.Estimated glomerular filtration rate(eGFR) was calculated with the simplified MDRD equation modified by a Chinese coefficient.The risk factors associated with CKD were also investigated.Results There were no significant differences between urban and rural residents in the prevalence of albuminuria (5.22％ vs 5.47％) and hematuria (1.07％ vs 1.11％)(all P＞0.05).The prevalence of renal lithiasis in rural residents was significantly higher than that in the town(10.54％ vs 6.95％)(P＜0.05).The decreased renal function between urban and rural residents(3.87％ vs 4.04％,P＞0.05) had no significant difference.The prevalence of CKD was 9.58％ in urban and 9.42％ in rural(P＞0.05).The prevalence of albuminuria according to the age distribution was different between urban and rural,which increased along with the age in urban but showed two peaks(30-40 years old and 60-74 years old) in rural.Based on logistic regression analysis,the risk factors for albuminuria were diabetes,hyperuricemia,the history of cardiovascular disease,chronic tonsillitis and HBsAg positive.The risk factors for kidney function decline were age,hyperuricemia,hypertension,diabetes,renal lithiasis and history of cardiovascular disease.The awareness rate of CKD in urban was significantly higher than that in rural (14.45％ vs 6.27％,P＜0.05).Conclusions The prevalenceof CKD has no significant difference between urban and rural in Guangxi province.The awareness rate of CKD in urban is significantly higher than that in rural.It is needed to enhance the prevention and treatment of CKD in rural.

Volatility can influence the lifetime of particles in the atmosphere, and provide useful information on the formation of secondary aerosol. The previous studies generally utilized thermodenuder ( TD ) to investigate the volatility behavior of particles. Using TD, semivolatile species are vaporized at different temperature, and the vaporized gas is adsorpted by activated charcoal. However, carbon might be emitted from activated charcoal under high temperature or activated charcoal ageing. In this study, a new method was developed for the measurement of particle volatility by coupling a thermodiluter system to an online single particle aerosol mass spectrometer ( SPAMS) . Aerosol particles were passed into two different channels, and then analyzed by SPAMS. Through Channel 1, aerosol particles were heated to different temperature by heating tube, then non-volatile particles and volatile gas entered into the diluter. After diluting and cooling by diluent air, the non-volatile particles were analyzed by SPAMS. Through Channel 2, aerosol particles were analyzed directly by SPAMS without the heating process. Particle volatility was obtained by comparing the information ( particle size, particle number and mass spectrum ) of particles through Channels 1 and 2. Laboratory tests showed that the diluter could avoid the re-condensation of volatiles to the particles. This developed method was applied in the real time measurement of individual particle volatility in the spring of Guangzhou. The results showed that these particles were primarily comprised of highly volatile and moderate volatile species.

The influence on 10 kinds of ginsensides of different processed methods of Panacis Quinquefolii Radix was discussed. White Panacis Quinquefolii Radix (sliced and dried at -80 °C), red Panacis Quinquefolii Radix( steamed, sliced and dried at -80 °C) and commercial Radix Panacis Quinquefolii (dried by electric blast air) processed by different methods. HPLC-PDA-ESI- MS method was established before by our team. Ten kinds of ginsenosides of them were determined. The content of total ginsenosides were as follow: commercial Panacis Quinquefolii Radix > white Panacis Quinquefolii Radix > red Panacis Quinquefolii Radix. Compared with white Panacis Quinquefolii Radix, the content of Re, Rc, Rb3 and Rb2 of Red Radix Panacis Quinquefolii decreased but increased that of Rg,, Rb1. Both Rg2 and Rg, were not found in white Panacis Quinquefolii Radix and commercial Panacis Quinquefolii Radix by PDA detector, and low response in ESI-MS, while red Panacis Quinquefolii Radix was to the high content that of 0. 027% and 0.040 1%. The constituent of RA0 of red Panacis Quinquefolii Radix was higher than the other two. After Panacis Quinquefolii Radix processed, the kind and content of ginsensides were significantly changed. The constituent of some kinds of ginsensides was increased and some decreased. Rf was not found in all Panacis Quinquefolii Radix samples which were consistent with the former documents.
