Objective To investigate the distribution of TCM Syndromes of Parkinson's disease(PD).Methods The 125 PD patients were graded according to Hoehn-Yahr(H&Y) criteria for assessment.The assigned TCM physician investigated TCM syndromes of these patients with the structured questionnaire which was based on literature and experience of experts.Results Of 125 cases,96 ones(76.8%) presented a single syndrome,and 29 ones(23.2%) presented complex syndrome.The positive rate of main syndrome was in an order of deficiency of both the Spleen and Kidney(22.4%),yin deficiency of the Liver and Kidney(18.4%),yang deficiency of the Spleen and Kidney(16%),qi deficiency of both qi and yin(15.2%),phlegm-heat stirring up the wind(12.8%),qi deficiency with blood stasis(4.8%),deficiency of both yin and yang(4%),damp abundance due to the Spleen deficiency(3.2%),endoretention of damp heat(1.6%),stagnation of the Liver qi with deficiency of the Spleen and Liver fire flaring(0.8%).There existed a significant difference in the distribution of TCM syndromes in H&Y 1.0~1.5 and H&Y 2.0~3.0(P

Autologous stem cell transplantation(ASCT) significantly increased the complete response rate(CR) and long-term survival in the patients younger than 65 years with multiple myeloma(MM). ASCT in the early stage of disease is currently considered the standard therapy in younger patients with newly diagnosed MM. High-dose melphalan with 200 mg/m2 is still considered the best conditioning. Double autotransplant is recommended for the patients without having VGPR after the first ASCT. Novel pretransplant induction regimens and conditioning with novel drugs such as bortezomib could improve the effect of ASCT. The best curative approach in multiple myeloma is allogeneic transplantation (allo-HSCT) with much higher CR. The long-term survival of patients receiving conventional/myeloablative conditioning (MAC) allo-HSCT is not better than that of the ASCT because of higher transplant-related mortility (TRM). Allo-HSCT with MAC has almost universally been replaced by the dose-reduced intensity conditioning allogeneic transplantation (Allo-RIC),which has lower TRM. More patients and long-term follow-up are needed to test the efficacy of single ASCT followed by Allo-RIC in patients with multiple myeloma.

Abstract: Objective To understand the difference of DNA sequence and RNA sequence of paired pol region in HIV patients in constructing HIV genetic transmission network, and to provide scientific data for constructing molecular transmission networks using DNA sequences. Methods　The whole blood and plasma samples of HIV patients living in 2014 and newly reported in 2015-2018 in Liuzhou, Guangxi, were collected, DNA and RNA sequences were extracted, amplified, sequenced, spliced and aligned, and then genetic transmission networks were constructed, and the connectivity consistency of genetic transmission networks constructed by DNA and RNA sequences was compared. Results In this study, a total 2 983 participants were investigated, which were 2014 baseline and 2015-2018 newly reported HIV patients, of which 2 590 participants were only DNA sequences in 2014 baseline, 196 HIV patients were both DNA and RNA sequences of paired pol region in 2014 baseline, and 197 newly reported HIV patients were both DNA and RNA sequences of paired pol region in 2015-2018. In 393 DNA and RNA sequences of paired pol region, the genotype of DNA sequence and RNA sequence were consistent, and there was no statistically significant difference in genetic distance between paired DNA sequences and RNA sequences (Z=-2.72, P=1.00). The connection consistency rate of genetic transmission networks constructed by DNA and RNA sequences of paired pol region of 2015-2018 newly reported with the baseline DNA sequences was 91.4% (108/197). And the connection consistency rate of genetic transmission networks constructed by DNA and RNA sequences of paired pol region of 2015-2018 newly reported with the baseline RNA sequences was 97.0% (191/197). There was no statistical difference in antiretroviral therapy to reduce the risk of HIV secondary transmission between genetic transmission networks constructed by DNA and RNA sequences of paired of pol gene newly reported from 2015 to 2018 with baseline DNA sequence. Conclusion　DNA sequence and RNA sequence of paired pol region of HIV patients have good consistency in genotype, genetic distance, and genetic transmission network construction, and both DNA and RNA sequences can be used for genetic transmission network analysis.

A new method for determining transaminase activity based on the color change of the reaction solution was established, by using alanine-dependent transaminase VfTA from Vibrio fluvialis JS17 as the research object coupled with pyruvate oxidase and horseradish peroxidase. After the optimization of the conditions, the linear relationship between VfTA activity units and the absorbance at 400 nm was investigated. This method was also applied to determine the activity of commercial transaminase ATA117. The results showed that the detection limit of transaminase VfTA activity was up to 0. 45 U/mL and the detection limit of ATA117 activity was up to 0. 5 U/mL. The transaminase activity could be quickly judged according to the color depth of the reaction solution.

Fine particulate matter (PM2.5) not only directly damages lung tissue, but also can be absorbed into blood through alveolar capillaries, which is toxic to the cardiovascular system. PM2.5 can affect lipid metabolism, endothelial function, coagulation and thrombosis through oxidative stress, inflammatory reaction, autonomic nervous dysfunction and immune regulation abnormality, so that it promote arteriosclerosis, plaque instability, and increase the morbidity and mortality of cardiovascular disease. We reviewed the effects and mechanisms of PM2.5 on arteriosclerosis, in order to provide the evidence for the studies into prevention of cardiovascular diseases caused by air pollution.
