ABSTRACT

OBJECTIVE@#To evaluate the clinical efficacy and safety of Congrong Shujing Granules ( , CSGs) in treating patients with Parkinson's disease (PD) and Chinese medicine (CM) syndrome of Shen (Kidney) essence deficiency, and to investigate the potential mechanism involving efficacy through a transcriptome sequencing approach.@*METHODS@#Eligible PD patients with syndrome of Shen essence defificiency were randomly assigned to a treatment group or a control group by a random number table, and were treated with CSGs combined with Western medicine (WM), or placebo combined with WM, respectively. Both courses of treatment lasted for 12 weeks. The Unifified Parkinson's Disease Rating Scale (UPDRS) score, the PD Question-39 (PDQ-39) score, CM Syndrome Scale score, and drug usage of all patients were evaluated before and after treatment. Safety was evaluated by clinical laboratory tests and electrocardiographs. Blood samples from 6 patients in each group were collected before and after the trial and used for transcriptomic analysis by gene ontology analysis and Kyoto Encyclopedia of Genes and Genomes pathway analysis. Differentially expressed genes were validated using reverse transcription-polymerase chain reaction.@*RESULTS@#A total of 86 PD patients were selected from the Third Affifiliated People's Hospital of Fujian University of Traditional Chinese Medicine between January 2017 and December 2017. Finally, 72 patients completed the trial, including 35 in the treatment group and 37 in the control group. When compared with the control group after treatment, patients in the treatment group showed signifificant decreases in UPDRS sub-II score, PDQ-39 score, CM syndrome score, and Levodopa equivalent dose (P0.05). A possible mechanism of clinical effificacy was proposed that involved regulating cell metabolism-related processes and ribosome-related pathways. Treatment with CSGs had shown to affect relevant gene loci for PD, including AIDA, ANKRD36BP2, BCL2A1, BCL2L11, FTH1P2, GCH1, HPRT1, NFE2L2, RMRP, RPS7, TGFBR1, WIPF2, and COX7B.@*CONCLUSIONS@#CSGs combined with WM can be used to treat PD patients with CM syndrome of Shen essence defificiency with a good safety. The possible mechanism of action and relevant gene loci were proposed. (Registration No. ChiCTR-IOR-16008394).

ABSTRACT

To develop an attenuated vaccine against the highly pathogenic porcine reproductive and respiratory syndrome (HP-PRRS) virus, the HP-PRRS virus strain TJ was attenuated by serial passages and plaque cloned every 5 to 10 passages in Marc-145 cells. Genetic variation and pathogenicity of HP-PRRSV strain TJ in the course of attenuation were analyzed. The results showed that the strain TJ sustained various sequence changes during the course of attenuation. Fifty-eight amino acids changes and a new continuous 120 amino acids deletion after the discontinuous 30 amino acids deletion (sites 481 and 533-561) occurred in strain TJ passages 140, and the position of 120 amino acids deletion was between 628 to 747 according to VR-2332. Animal test showed that the pathogenicity of strain TJ passages 20 was attenuated obviously, so we presume that genetic variation in nonstructural protein nsp2-nsp5, nsp7 and structural protein GP5 during the attenuation provides the molecular bases for the observed attenuated phenotype.
