Chinese Journal of Integrated Traditional and Western Medicine 2014;34(4):471-474
OBJECTIVETo investigate the effect of Xiaoyao Powder (XP) and its compatible prescriptions on the ethology, morphology, and activities of neurotransmitters, thus exploring their effects and mechanism in preventing and treating D-galactose induced Alzheimer's disease (AD) model mice, and clarifying the compatibility mechanism for soothing Gan, nourishing blood, and invigorating Pi.
METHODSSixty SPF mice were randomly divided into the blank control group, the model group, and the XP group, Shugan Jianpi group (SJ), Shugan Yangxue group (SY), and Jianpi Yangxue group (JY), 10 in each group.The AD mouse model was prepared by peritoneal injecting D-galactose. Meanwhile, mice in the blank control group and the model group were administered with physiological saline (at the daily dose of 24 mL/kg) by gastrogavage. Mice in the XP group (2.485 g/kg), the SY group (1.136 g/kg), the SJ group (1.775 g/kg), and the JY group (2.059 g/kg) were administered with corresponding medicated decoction by gastrogavage, with the gastric volume of 24 mL/kg. On the 41st day the training of capability for learning and memory was started. On the 42nd day capability for learning and memory was tested. The brain tissue was cut. One half was used to determine the contents of homogenate acetyl cholinesterase (AchE), choline acetyltransferase (ChAT), and monoamine oxidase (MAO).Another half was used to carry out morphological observations.
RESULTSThe capability for learning and memory could be improved and the latency time could be lowered in all the treatment groups. Besides, the homogenate AchE and MAO could also be elevated, ChAT could be lowered; the morphology, number, and distribution of neurons could be improved. But the improvement of ethology, morphology, and activities of neurotransmitters were most obviously seen in the XP group.
CONCLUSIONSXP could improve the ethology, morphology, and activities of neurotransmitters, and showed better effects on prevention and treatment of AD. The rationality of compatibility methods and combination thinking ways of soothing Gan, nourishing blood, and invigorating Pi were clarified.

5.Recent advances in drug development targeting bile acids transporters and related disease
Acta Pharmaceutica Sinica 2022;57(12):3576-3586
Bile acids (BAs) are a major component of bile salt, which plays a vital role in the metabolism of lipids in humans. Ninety-five percent of bile acids are recycled by the enterohepatic circulation (EHC), and therefore EHC is essential for bile acid homeostasis. There are four transporters that mediate the transmembrane transport of bile acids, each of which plays an important role in the enterohepatic circulation. Gene defects in bile acid transporters can lead to disorders of the enterohepatic circulation, ultimately leading to clinical phenotypes such as metabolic diseases and even death. Bile transporter expression is altered in patients with various metabolic disease states, suggesting that disruption of bile acid transporters may be a pivotal pathological mechanism for the development of metabolism diseases. Thus, many drugs targeting bile acid transporters are being developed. We provide a concise overview of the progress of bile acid transporters research, discuss the relationship between different bile acid transporters and disease development, and summarize the current progress in drug development targeting bile acid transporters.

Objective To investigate demographic factors implicated in the functional maturation of autologous arteriovenous fistula in a population of patients with end-stage renal disease. Methods The data of 335 consecutive patients with end-stage renal disease who were performed autologous arteriovenous fistula from January 2010 to December 2015 were analyzed retrospectively. The parameters affecting autologous arteriovenous fistula functional maturation were screened. Results Overall arteriovenous fistula functional maturation rate was 78.14%(218/279). The arteriovenous fistula functional maturation rate was 68.33%(82/120) in diabetes and 85.54%(136/159) in non-diabetes, and there was significant difference (χ2=11.844, P<0.01). The arteriovenous fistula functional maturation rate was 62.26%(33/53) in hypoproteinemia and 81.86%(185/226) in non-hypoproteinemia, and there was significant difference (χ2=9.648, P<0.01). Diabetes and hypoproteinemia were the risk factors to promote functional maturation (OR=6.003, 8.476). The arteriovenous fistula functional maturation rate was 87.10%(81/93) in calcium channel blockers using and 73.66%(137/186) in non-calcium channel blockers using, and there was significant difference (χ2=6.556, P<0.05). Calcium channel blockers was the protective factor for promoting functional maturation (OR=0.086). Conclusions Diabetes and hypoproteinemia are found to be associated with functional non-maturation, while calcium channel-blocker agents are associated with better functional maturation.

Objective To screen and identify the predominant T-and B-cell ( T-B) combined an-tigenic epitopes on the outer membrane protein Loa22 of pathogenic Leptospira interrogans ( L.interrogans) stains and to further analyze their immunogenicity.Methods PCR analysis was used to detect loa22 gene in L.interrogans strains belonging to eight different serogroups or serovars prevalent in China.The PCR prod-ucts were sequenced after T-A cloning.A prokaryotic expression system for loa22 gene of L.interrogans sero-group Icterohaemorrhagiae serovar Lai strain Lai was constructed.The expressed recombinant protein rLoa22 was extracted by Ni-NTA affinity chromatography.The rabbit anti-rLoa22 serum samples and IgG were pre-pared.The T-B combined antigenic epitopes on Loa22 protein were predicted by using professional bioinfor-matic softwares.Phage display in combination with Western blot assay and ELISA were performed to identify the immunogenicity of the recombinant phage PⅢ protein-displayed and artificially-synthesized T-B com-bined antigenic epitopes, respectively.MTS assay and ELISA were performed to detect the activation of T cells and the expression of IL-2, IL-4 and IFN-γinduced by T-B combined antigenic epitopes, respectively. Results All of the tested pathogenic Leptospira strains were positive for loa22 gene, sharing 85.5%-99.8%homologies in nucleotide sequences and 93.9%-99.5%homologies in amino acid sequences.The construc-ted prokaryotic expression system for loa22 gene efficiently expressed the rLoa22 protein.Among four T-B combined antigenic epitopes (Loa22-77, Loa22-90, Loa22-125 and Loa22-157), only Loa22-90 epitope presented a strong positive band in Western blot analysis.The proliferation of CD4+T cells and the expres-sion of IL-2 ( Th1 ) and IL-4 ( Th2 ) were significantly enhanced by the stimulation with Loa22-90 epitope peptide (P<0.05).Conclusion Loa22 protein is a sequence-conserved genus-specific outer membrane protein of L.interrogans.The Loa22-90 epitope is the predominant T-B combined antigenic epitope of Loa22 protein, which might be used as a candidate antigenic epitope in the development of multiple antigenic pep-tide ( MAP) vaccines against Leptospira infection.
