Intestinal dysbiosis and disrupted bile acid(BA)homeostasis are associated with obesity,but the precise mechanisms remain insufficiently explored.Hepatic protein phosphatase 1 regulatory subunit 3G(PPP1R3G)plays a pivotal role in regulating glycolipid metabolism;nevertheless,its obesity-combatting potency remains unclear.In this study,a substantial reduction was observed in serum PPP1R3G levels in high-body mass index(BMI)and high-fat diet(HFD)-exposed mice,establishing a positive correlation between PPP1R3G and non-12α-hydroxylated(non-12-OH)BA content.Additionally,hepatocyte-specific overexpression of Ppp1r3g(PPP1R3G HOE)mitigated HFD-induced obesity as evidenced by reduced weight,fat mass,and an improved serum lipid profile;hepatic steatosis alleviation was confirmed by normalized liver enzymes and histology.PPP1R3G HOE considerably impacted systemic BA homeostasis,which notably increased the non-12-OH BAs ratio,particularly lithocholic acid(LCA).16S ribosomal DNA(16S rDNA)sequencing assay indicated that PPP1R3G HOE reversed HFD-induced gut dysbiosis by reducing the Firmicutes/Bacteroidetes ratio and Lactobacillus population,and elevating the relative abundance of Blautia,which exhibited a positive correlation with serum LCA levels.A fecal microbiome transplantation test confirmed that the anti-obesity effect of hepatic PPP1R3G was gut microbiota-dependent.Mechanistically,PPP1R3G HOE markedly suppressed hepatic cholesterol 7α-hydroxylase(CYP7A1)and sterol-12α-hydroxylase(CYP8B1),and concurrently upregulated oxysterol 7-α hydroxylase and Takeda G protein-coupled BA receptor 5(TGR5)expression under HFD conditions.Furthermore,LCA administration significantly mitigated the HFD-induced obesity phenotype and elevated non-12-OH BA levels.These findings emphasize the significance of hepatic PPP1R3G in ameliorating diet-induced adiposity and hepatic steatosis through the gut microbiota-BA axis,which may serve as potential ther-apeutic targets for obesity-related disorders.

Objective To analyse the risk factors for postoperative infection in traumatic tibial plateau fractures and to construct a Nomogram prediction model.Methods One hundred and forty-eight patients with traumatic tibial plateau fractures who underwent surgery in our hospital from October 2019 to August 2021 were selected for the study,and were divided into an infected group(n=20)and an uninfected group(n=128)according to whether they developed infection after surgery.The general data of the two groups were compared;the predictive value of statistically significant continuous variables was analysed using the ROC experiment;the risk factors affecting postoperative infection in traumatic tibial plateau fractures were analysed using the logistic regression experiment;and the clinical efficacy of the Nomogram model was verified using internal data.Results In the comparison of general data such as age and gender between the two groups,the differences were not statistically significant(P>0.05).Compared with the uninfected group,patients in the infected group had a higher percentage of diabetes mellitus,open fracture type,and osteofascial compartment syndrome,and longer operative time and hospital stay(P<0.05);diabetes(yes),fracture type(open),osteofascial compartment syndrome(yes),and operative time(>3 h)were risk factors affecting postoperative infection in traumatic tibial plateau fractures.The AUCs for operative time and hospital stay were not 0.792 and 0.651;the optimal stage values were not 3 h and 13 d(P<0.05);the Nomogram model predicted a C-index of 0.744(0.651-0.807)for the risk of postoperative infection in traumatic tibial plateau fractures.The model predicted the risk of infection after traumatic tibial plateau fracture at a threshold of>0.09.Conclusion Diabetes mellitus(yes),fracture type(open),osteofascial compartment syndrome(yes),and operative time(>3 h)were risk factors affecting postoperative infection in traumatic tibial plateau fractures,and the Nomogram model constructed based on the above variables had good predictive value.

10.Morin Mediates Protective Effects on Bone in Aged Rats by Inhibiting ERK1/2-p38 Signaling Pathway
Journal of Sun Yat-sen University(Medical Sciences) 2024;45(2):261-267
ObjectiveTo investigate the effects of morin treatment on bone metabolism and bone mass in aged rats, and to clarify the possible mechanism. MethodsTen young female Sprague-Dawley rats (3 months old) and 20 old female Sprague-Dawley rats (24 months old) were randomly divided into three groups: Control group (CON, 10 young rats); Model group (MOD, 10 young rats); 10 old rats and SangHuangSu Group (SSS, 10 old rats). During the experiment, the SSS group received intraperitoneal injection of morin (10 mg / kg) daily. The treatment lasted for 12 weeks. After treatment, Micro-CT, HE stained sections, serological tests and Western blot were used to observe the treatment effect and possible mechanism. ResultsAfter 12 weeks of treatment, compared with MOD group, the number and density of bone trabeculae in SSS group were significantly improved. The BMD, Conn. D, Tb. N, Tb.Th and Tb.Sp of the left femur in the SSS group were significantly better than those in the MOD group(P <0.05). After 12 weeks of treatment, the levels of CTX-1, osteocalcin, TRACP-5b and PINP in SSS group were significantly lower than those in MOD group(P <0.05). Compared with the MOD group, the ERK1/2-p38 signal pathway was significantly inhibited and the levels of ERK1/2 and p38 were significantly decreased in the SSS group(P <0.05). ConclusionMorin pigment mediates the protective effect on the bones of aged rats by inhibiting the ERK1/2-p38 signaling pathway and reducing bone turnover.
