Differences of the structure, succession and function of Clostridial communities between jiupei and pit mud during Luzhou-flavour baijiu fermentation / 生物工程学报

Clostridia inhabiting in jiupei and pit mud plays key roles in the formation of flavour during the fermentation process of Luzhou-flavour baijiu. However, the differences of Clostridial communities between jiupei and pit mud remains unclear. Here, the species assembly, succession, and metabolic capacity of Clostridial communities between jiupei and pit mud were analysed by high-throughput sequencing and pure culture approaches. The ratio of Clostridial biomass to bacterial biomass in the pit mud was relatively stable (71.5%-91.2%) throughout the fermentation process. However, it varied widely in jiupei (0.9%-36.5%). The dominant Clostridial bacteria in jiupei were Clostridium (19.9%), Sedimentibacter (8.8%), and Hydrogenispora (7.2%), while Hydrogenispora (57.2%), Sedimentibacter (5.4%), and Caproiciproducens (4.9%) dominated in the Clostridial communities in pit mud. The structures of Clostridial community in pit mud and jiupei were significantly different (P=0.001) throughout fermentation. Isolated Clostridial strains showed different metabolic capacities of volatile fatty acids in pure culture. Spatial and temporal heterogeneity of Clostridial communities existed in the baijiu fermentation pit, which was closely related to the main flavour components of Luzhou-flavour baijiu.

Bronchiolitis Obliterans Syndrome after Hematopoietic Stem Cell Transplantation Treated by WANG Shu-chen with Tongue Picture as the Key Link / 中国中医药信息杂志

This article introduced professor WANG Shu-chen's experience in picture treating bronchiolitis obliterans syndrome (BOS) after hematopoietic stem cell transplantation with tougue picture as the key link. Patients with BOS showed deficiency of essence of tongue crack, which should be treated by warming kidney yang, replenishing essence and marrow; fester tongue for qi disorder, inflammation caused by fire, which should be treated by regulating qi, and clearing heat; exfoliative fur accumulation, which should be treated with blood stasis and toxin, removing blood stasis and toxin; thick and greasy fur, which should be treated by warming spleen and activating spleen.

Toll like receptor expression in spleen of rat skin transplantation model / 中国免疫学杂志

Objective:The expression patterns of TLR4,9,10 in the rat spleen were compared between the rat model of acute skin-transplant rejection and physiologically normal rats ,and their physiological significance were accessed.Methods:6 Wistar and 6 SD rats were used as donors ,and another 24 SD rats were used as recipients which were divided into 4 groups of 6.The same back skin slices were transplanted from donor to recipient , Group A:allograft ( Wistar to SD );Group B:homograft ( SD to SD );Group C:autograft;and Group D:normal SD rats as control.Rat spleens were collected at 1,4,7,10,14,and 21 days after surgery ,and mRNA levels of TLR4,9,10 in splenic mononuclear cells were determined by real-time PCR and corresponding protein expression was accessed by immunohistochemistry.Results:TLR4,9,10 mRNA levels of Group A were significantly higher than that of Group B and C ( P0.05).TLR4,9,10 expressions were moderate (++) to strong (+++) in Group A,and generally weak (+) in Group B,C and D.Conclusion:The patterns of TLR4,9,10 mRNA and protein expression in the rat model of acute skin-transplant rejection indicate that the three genes are involved in acute transplant rejection;the three genes may be expressed coordinately;inhibition of the Toll-like receptors may provide therapeutic targets for acute transplant rejection.
