Objective To explore the effect of group psychological training on the mental health and self consistency of nurses from operating rooms.Methods 52 nurses of an operating room were randomized into the treatment group(n=25)and the control group(n=27): The latter received humane care and instructions for mental self care and the former received group psychological training for 8 weeks based on the same treatment as in the control group.Symptom checklist 90(SCL-90)and self consistency and congruence scale(SCCS)were used to assess and compare the difference of the two groups before and after training.Results The intra-and inter-group comparisons between pre-and post-intervention showed statistical differences in terms of the total score by SCL,interpersonal sensitivity,depression and hostility,total score by SCCS and the score on the subscale of inconsistency between themselves and their experience(all P<0.05 or P<0.01).Conclusion Group psychological training can effectively improve the level of mental health and self consistency of OR nurses and thus can improve the total psychological status of the OR nurses.

BACKGROUND:The in vitro construction of intestinal smooth muscle layer,as an important component of the intestinal wall,has attracted much attention in the bionic construction of tissue-engineered intestinal canal. OBJECTIVE:To explore the effects of cyclic mechanical stretching on the growth activity of intestinal smooth muscle cells and the expression of functional genes within collagen strips. METHODS:The collagen band culture system of intestinal smooth muscle cells was constructed using a self-designed collagen strip stretching culture device with self-made rat tail collagen as a scaffold and primary rat intestinal smooth muscle cells as seed cells.EthD-1/Calcein-AM cell activity staining,magenta staining,cytoskeleton-Ki67 immunofluorescence staining were used to observe the growth activity and proliferation of the cells,and quantitative RT-PCR was used to detect the expression of desmin,α-sma,and vimentin functional genes. RESULTS AND CONCLUSION:The collagen band culture system of intestinal smooth muscle cells was successfully constructed,and intestinal smooth muscle cells in the band had good cell activity.The number of Ki67 positive cells increased and desmin,α-sma and vimentin were significantly overexpressed under cyclic stretching and dynamic culture conditions(P＜0.001).To conclude,mechanical stimulation is beneficial to maintain the growth phenotype of smooth muscle cells and promote their functional differentiation during three-dimensional culture in vitro.

Recent studies heve demonstrated that Akkermansia muciniphila (A.muciniphila) plays an important role in human health and disease , including regulating the development of the immune system and the metabolic phenotype of the host.This article reviews the research progress on A.muciniphila in recent years, focusing on the basic characteristics , the influencing factors of colonization , and the underlying mechanism of maintaining intestinal homeostasis of A.muciniphila.Additionally, the article summarizes the potential association between A.muciniphila and the chronic metabolic diseases such as obesity , atherosclerosis,diabetes mellitus and infectious diseases.The perspect of A.muciniphila as a new generation of probiotics in clinical medicine and the challenge for its industrialization are also discussed in the article .

Nonalcoholic fatty liver disease (NAFLD) is a hepatic manifestation of metabolic syndrome and a common cause of liver cirrhosis and cancer. Akkermansia muciniphila (A. muciniphila) is a next-generation probiotic that has been reported to improve metabolic disorders. Emerging evidence indicates the therapeutic potential of A. muciniphila for NAFLD, especially in the inflammatory stage, nonalcoholic steatohepatitis. Here, the current knowledge on the role of A. muciniphila in the progression of NAFLD was summarized. A. muciniphila abundancy is decreased in animals and humans with NAFLD. The recovery of A. muciniphila presented benefits in preventing hepatic fat accumulation and inflammation in NAFLD. The details of how microbes regulate hepatic immunity and lipid accumulation in NAFLD were further discussed. The modulation mechanisms by which A. muciniphila acts to improve hepatic inflammation are mainly attributed to the alleviation of inflammatory cytokines and LPS signals and the downregulation of microbiota-related innate immune cells (such as macrophages). This review provides insights into the roles of A. muciniphila in NAFLD, thereby providing a blueprint to facilitate clinical therapeutic applications.

Both immunosuppressants and antibiotics (ABX) are indispensable for transplant patients. However, the former increases the risk of new-onset diabetes, whereas the latter impacts intestinal microbiota (IM). It is still unclear whether and how the interaction between immunosuppressants and ABX alters the IM and thus leads to glucose metabolism disorders. This study examined the alterations of glucose and lipid metabolism and IM in mice exposed to tacrolimus (TAC) with or without ABX. We found that ABX further aggravated TAC-induced glucose tolerance and increased insulin secretion. Combined treatment resulted in exacerbated lipid accumulation in the liver. TAC-altered microbial community was further amplified by ABX administration, as characterized by reductions in phylum Firmicutes, family Lachnospiraceae, and genus Coprococcus. Analyses based on the metagenomic profiles revealed that ABX augmented the effect of TAC on microbial metabolic function mostly related to lipid metabolism. The altered components of gut microbiome and predicted microbial functional profiles showed significant correlation with hepatic lipid accumulation and glucose disorders. In conclusion, ABX aggravated the effect of TAC on the microbiome and its metabolic capacities, which might contribute to hepatic lipid accumulation and glucose disorders. These findings suggest that the ABX-altered microbiome can amplify the diabetogenic effect of TAC and could be a novel therapeutic target for patients.
