The central amygdala (CeA) is a crucial modulator of emotional, behavioral, and autonomic functions, including cardiovascular responses. Despite its importance, the specific circuit by which the CeA modulates blood pressure remains insufficiently explored. Our investigations demonstrate that photostimulation of GABAergic neurons in the centromedial amygdala (CeMGABA), as opposed to those in the centrolateral amygdala (CeL), produces a depressor response in both anesthetized and freely-moving mice. In addition, activation of CeMGABA axonal terminals projecting to the nucleus tractus solitarius (NTS) significantly reduces blood pressure. These CeMGABA neurons form synaptic connections with NTS neurons, allowing for the modulation of cardiovascular responses by influencing the caudal or rostral ventrolateral medulla. Furthermore, CeMGABA neurons targeting the NTS receive dense inputs from the CeL. Consequently, stimulation of CeMGABA neurons elicits hypotension through the CeM-NTS circuit, offering deeper insights into the cardiovascular responses associated with emotions and behaviors.

Objective To explore the early detection value of estimated glucose disposal rate(eGDR)for non-alcoholic fatty liver disease(NAFLD),providing a simple tool for precise clinical intervention.Methods A cross-sectional analysis was conducted on totally 3 262 participants with complete data from the National Health and Nutrition Survey Database of the United States from 2007 to 2018.Univariate regression and multivariate logistic regression analyses were used to explore the correlation between the estimated glucose treatment rate and the incidence of non-alcoholic fatty liver disease.Subgroup analysis,restricted cubic spline and threshold effect analysis were conducted to investigate the potential factor influences and nonlinear relationships.Result Among all the included populations,948 cases(25.29%)were diagnosed with NAFLD,and the number gradually decreased with the increase of the estimated glucose treatment rate(P<0.001).Multivariate logistic regression showed that the estimated grape processing rate was negatively correlated with non-alcoholic fatty liver disease(OR=0.86,95%CI:0.83~0.88,P<0.001),and when the estimated glucose processing rate was≥10.246,it could significantly reduce the risk of non-alcoholic fatty liver disease(OR=0.20,95%CI:0.10~0.39,P<0.001),and stratified analysis further confirmed this result.Conclusion The eGDR is significantly associated with the incidence risk of NAFLD.A higher eGDR indicates a lower risk of NAFLD.This implies that in clinical practice,the risk of disease detection can be quantified through this indicator,thereby identifying potential patients earlier and initiating intervention.Countermeasures As decision-makers,they should strengthen public health education on non-alcoholic fatty liver disease,reduce health risks by promoting healthy diets and lifestyle interventions,and pay attention to the cardiovascular health of high-risk groups for non-alcoholic fatty liver disease.At the same time,promote the research and application of drugs,and dynamically adjust policies through continuous disease monitoring to comprehensively reduce the burden of non-alcoholic fatty liver disease.

OBJECTIVE:
To observe and compare the shoulder joint function, complications and clinical effects of hemiarthroplasty and open reduction and locking plate in the treatment of comminuted proximal humeral fracture (Neer IV) with 3D printing technique.
METHODS:
From March 2012 to April 2018, 31 middle age and elderly patients with comminuted proximal humeral fractures (Neer IV) were treated, including 4 males and 27 females, aged from 55 to 94 years old with an average age of 71 years, with a course of 1 to 3 years. Among them, 20 cases were treated with open reduction and locking plate internal fixation (ORIF group) and 11 cases were treated with lower half shoulder replacement (HA group) assisted by 3D printing technology. Using CT data and Mimics software of Materialise Company in Belgium, the reconstruction of fracture was simulated on computer. The height of fracture end to humeral head, the height of tubercle to humeral head, the angle of humeral head backward obliquity were measured to assist the hemiarthroplasty. Follow-up and X-ray examination were performed, the incidence of complications were observed, and Neer score was used for the shoulder joint function.
RESULTS:
Thirty-one patients were followed up for 1 to 3 years with an average of 2 years. In HA group, there was no prosthesis loosening, fracture and subsidence, the head of artificial humerus was intact, the fracture of nodules and nodules did not heal in 1 case, Neer score was 84.18±3.55; in ORIF group, there were 8 cases of proximal humerus bone resorption, 1 case of fracture nonunion, 1 case of internal fixation loosening, Neer score was 55.91±10.78; there was significant difference in Neer score of shoulder joint function between the two groups(<0.05).
CONCLUSIONS

OBJECTIVETo explore the diagnosis and treatment of tarsometatarsal joint complex injury (TJC).
METHODSFrom January 2007 to January 2009,16 patients with tarsometatarsal joint complex injury were treated with open reduction and internal fixation. There were 12 males and 4 females, ranging in age from 21 to 45 years with an average of 34.1 years. Seven cases were left and 9 cases were right and all injuries caused by direct violence. Four cases caused by traffic accident 5 by fall from high and 7 by crush injury. Intercuneiform dislocation were in 11 cases, naviculocuneiform joint dislocation in 3 cases and cuboid fracture in 2 cases. All the cases were three column injuries. According to the situation of exploring and the stability, screw fixation was used for intertarsal joint, internal and middle column tarsometatarsal joint, the Kirschner wire fixation for external column and miniature plate fixation for comminuted fracture of metatarsal bones and compressible fracture of cuboid. The criteria of the AOFAS Foot and Ankle Surgery by the United States Association of ankle-rear foot functional scale was used to evaluate the clinical effect.
RESULTSAll the patients were followed up,the duration ranged from 6 to 18 months(averaged 12.6 months). According to the score system of AOFAS,the total score was (74.6+/-10.4 ) points, including pain items of (29.3+/-5.9), the score of functional items of (32.4+/-5.6) points, and power lines of (12.9+/-2.6). All the incisions were primarily healed without infection, skin necrosis,fixture broken or loosen. Three cases received arthrodesis due to osteoarthritis. Four cases were followed up continually because they only had the radiologic osteoarthritis without pain.
CONCLUSIONAnatomical reduction and stable fixation is the key point of the treatment of tarsometatarsal joint complex injury. Open reduction and internal fixation at the first stage is good for secondary arthrodesis.
