The triglyceride-glucose(TyG)index has emerged as a novel metabolic marker,and research on it in the intensive care unit(ICU)has gradually increased in recent years.The TyG index combines the levels of triacylglycerol(TG)and glucose,reflecting the body's insulin resistance(IR)and metabolic status,and its potential clinical applications have garnered widespread attention.Current studies indicate a significant association between the TyG index and the prognosis of ICU patients,metabolic syndrome,and various critical illnesses.However,despite some studies revealing the potential clinical value of the TyG index in critically ill patients,there is still a lack of systematic reviews to comprehensively assess the application status of this indicator in the ICU setting.This article aims to review the clinical applications of the TyG index in ICU patients and its relationship with prognosis,metabolic syndrome,and critical illnesses,emphasizing its importance in the assessment and management of critically ill patients,with the hope of providing references and insights for future related research.

Objective:To explore the feasibility and and clinical efficacy of lingual mucosa replacement ureteral stenosis repair and plasty for the treatment of long segment ureteral polyps.Methods:Clinical data of 3 patients (4 sides) with long-segment ureteral polyps admitted to the Second Hospital of Lanzhou University from October 2017 to October 2019 were retrospectively analyzed. Two cases were male and one case was female. The ages were22, 16, and 45 years old. Preoperative urologic ultrasound, CT urography and ureteroscopy were performed. The lesions were located on the left side in 3 cases and on the right side in 1 case; the stenosis was located in the middle and upper ureter; the length of the ureteral stenosis was 6, 7, 6, and 6 cm, respectively; and the preoperative blood creatinine was 72, 85, and 70 μmol/L, respectively. Three cases underwent ureteral stenosis repair and plasty with tongue mucosal substitution. During the operation, the ureter was fully exposed and longitudinally incised, polyps were removed, and 7.0-10.0 cm long and 1.5-2.0 cm wide lingual mucosa was harvested according to the length of the stenosis, and then the lingual mucosa was transplanted to the muscular layer and the inner surface of the sheath in the stenosed ureter, fixed with 6-0 thread until the muscular layer was rolled into shape and wrapped with a large omentum. All of them left one double-J tube in the ureter on the affected side. Perioperative results and complications were recorded. The patients' blood creatinine and anterior and posterior renal pelvic diameters were compared before and after treatment.Results:In our study, all three 4-sided surgeries were successfully completed without any serious intraoperative or postoperative complications (Clavien-Dindo score ≥ grade Ⅲ). Mean surgical. Time was (240.0±49.0) min, intraoperative bleeding was 50 ml, postoperative drain retention time was (6.3±2.5) d, and median postoperative hospitalization time was 6.5(3, 9)d. The double J-tube was removed at 3 months postoperatively, and renal function and imaging tests were reviewed. Because the postoperative follow-up results of patient 1 were missing, the mean value of blood creatinine in the other 2 patients was 73.0 μmol/L at 3 months postoperatively, which was significantly improved compared with the preoperative value of 58.2 μmol/L, and the difference was statistically significant ( P < 0.05). And the average value of anterior and posterior renal pelvic separation diameters of the other 2 patients after surgery was <5 mm, which was significantly improved compared with the preoperative value of 17.9 mm, but the difference was not statistically significant ( P>0.05).There was no restenosis in all 2 patients after surgery, and the intravenous urography showed that the ureter was patent after the surgery, and the degree of urinary obstruction did not aggravate. The group was followed up for 3 to 8 months (mean 4.7 months), and no recent complications have occurred so far. Conclusions:Lingual mucosa replacement ureteral stenosis repair and plasty for the treatment of ureteral polyps in the long segment has a high success rate and precise efficacy, and its operation is feasible.

Objective:To analyze the evaluation value of contrast-enhanced ultrasound (CEUS) combined with automatic volumetric ultrasound in the efficacy of neoadjuvant chemotherapy (NAC) for breast cancer.Methods:A retrospective study was conducted on 98 female patients with breast cancer admitted to Shaanxi Provincial Cancer Hospital from January to December 2022. All patients received 4 cycles of NAC, and underwent conventional ultrasound, automatic volumetric ultrasound, CEUS, and histopathological examination before and after treatment. Based on the post-treatment histopathological efficacy, patients were divided into the effective group ( n=67) and the ineffective group ( n=31). The CEUS and automatic volumetric ultrasound parameters before and after treatment, as well as the evaluation efficacy of these two types of parameters for NAC efficacy in breast cancer, were compared. The value of CEUS combined with automatic volumetric ultrasound in evaluating NAC efficacy for breast cancer was analyzed. Results:After NAC treatment, the CEUS parameters [time to peak (TTP) and arrival time (AT) of contrast agent] were longer than those before treatment, while the peak intensity (PI) was lower than that before treatment (all P<0.05); the automatic volumetric ultrasound parameters (tumor volume, area, thickness, length, and width) after NAC treatment were all smaller than those before treatment (all P<0.05). After treatment, the PI, volume, area, thickness, length, and width in the effective group were significantly smaller than those in the ineffective group, while the TTP and AT were significantly longer than those in the ineffective group (all P<0.05). Receiver operating characteristic (ROC) curve analysis showed that the area under the curve (AUC) of CEUS parameters and automatic volumetric ultrasound parameters for predicting effective NAC efficacy in breast cancer was 0.837(0.749-0.904) and 0.864(0.780-0.925), respectively, with no statistically significant difference between the two ( P=0.674). The AUC of the combined parameters for predicting effective NAC efficacy was 0.942(0.875-0.979), which was significantly higher than that of CEUS parameters or automatic volumetric ultrasound parameters alone ( Z=2.947, 2.135, P=0.003, 0.033). Conclusions:The combination of CEUS and automatic volumetric ultrasound parameters has high value in the efficacy evaluation of NAC for breast cancer and can be used as a clinical reference.

Objective To investigate the clinical and MRI features of primary non-urachal adenocarcinoma of the bladder.Methods The clinical and MRI data of 9 patients with histopathologically confirmed primary non-urachal adenocarcinoma of the bladder were analyzed retrospectively.Results Clinical symptoms of hematuria were present in 7 cases and urinary irritation symptoms in 5 cases among all patients.On MRI,1 case showed diffuse thickening of the bladder wall,8 cases showed a solitary nodular/cauliflower-like mass in the bladder with iso-hypointensity on T1WI and slight hyperintensity on T2WI,and patchy areas of hyperintensity on T2WI were seen in some patients.The apparent diffusion coefficient(ADC)ranging from 0.83× 10 3 mm2/s to 1.85× 10 3 mm2/s,mean ADC was approximately 1.23×10-3 mm2/s.Dynamic enhancement showed mild to marked enhancement,with some rim or compartmentalized enhancement,and patchy or diffusely distributed areas of no enhancement can be seen.No cystic changes and necrosis were seen in all patients,invasion of the muscularis propria and above were seen in 7 cases,lymph node metastasis was seen in 3 cases,and distant metastasis was seen in 2 cases.Conclusion Primary non-urachal adenocarcinoma of the bladder has certain clinical and MRI features.Patients often present with hematuria and urinary irritation symptoms,and some may present with blennuria.MRI shows that the lesion is solitary and more aggressive,with some hyperintensity on T2 WI,cystic changes and necrosis are rare.These features help to improve the accuracy of preoperative diagnosis to some extent,and the final diagnosis still relies on pathology.

Objective This study investigated lower limb biomechanics and lateral asymmetry during the continuous vertical jump(CVJ)landing process in individuals with unilateral functional ankle instability(FAI)and compared these characteristics with those of healthy individuals.Methods Fourteen males with unilateral FAI were selected as the experimental group,and 14 males without ankle joint injury were matched to the control group.Both the groups performed 30 CVJ landing tasks.Lower limb kinematic and kinetic characteristics during the 1st,15th,and 30th CVJ landings were synchronously collected using Vicon and Kistler equipment,and a 2×3 mixed analysis of variance was adopted for the data.Results In the execution of CVJ landing tasks,patients with FAI demonstrated no significant differences in the kinematic and kinetic characteristics of the affected limbs compared with healthy controls.However,a greater degree of lateral asymmetry was observed in the FAI group,particularly in the symmetry index(SI)of the vGRF peak.Despite the increase in the number of jump landings and consequent increase in fatigue levels,which led to adjustments in lower limb movement patterns,these adjustments did not appear to have a significant impact on the biomechanical characteristics and asymmetry of the affected limb in patients with FAI.Conclusions This study provides a theoretical basis for the prevention of recurrent ankle sprains in patients with FAI,as well as rehabilitation training prior to their return to sports.These findings underscore the importance of addressing lower limb asymmetry in the rehabilitation training of patients with FAI to reduce the risk of potential long-term injuries.When formulating rehabilitation plans for patients with FAI,particular attention should be paid to the correction of lower limb asymmetry with consideration of biomechanical adaptability under different states to achieve a more comprehensive rehabilitation outcome.

Immunothrombosis refers to the innate immune response caused by thrombosis in blood vessels(especially microvessels).Immunothrombosis is related to immune cells and specific thrombosis related molecules,producing intravascular scaffolds that promote pathogen recognition,inhibition,and destruction,thereby protecting the integrity of the host.However,abnormal or uncontrolled activation of immunothrombosis may be harmful to the host and serve as the foundation for various infectious and inflammatory related thrombotic diseases.Therefore,understanding the potential mechanisms of immunothrombosis plays a decisive role in developing more effective therapies for thrombosis treatment and prevention.This review provides an overview of the mechanisms of immunothrombosis in order to understand new treatment strategies for reducing the risk of immunothrombosis.

Objective:To investigate the clinical efficacy of percutaneous vertebral-disc plasty (PVDP) in the treatment of very severe osteoporotic vertebral compression fractures (vsOVCF).Methods:A total of 26 patients with vsOVCF were treated by PVDP at Department of Spine Surgery, The Second Affiliated Hospital, Nantong University from November 2019 to August 2021. They were 8 males and 18 females with an age of (77.9±5.2) years. Fracture sites: T11 in 9 cases, T12 in 13 cases, L1 in 7 cases, and L2 in 2 cases. The loss of vertebral height exceeded 2/3 of its original height. The curative effects were evaluated by comparing the visual analogue scale (VAS), Oswestry disability index (ODI) and local kyphosis angle (LKA) at preoperation, 1 day postoperation and the last follow-up.Results:This cohort was followed up for 12(10, 15) months. No obvious neurological damage or other serious complications occurred. The VAS scores [(2.9±0.7) and (2.2±0.7) points] and ODIs [28.0%±4.8% and 16.9%±4.0%] at 1 day postoperation and the final follow-up were significantly lower than the preoperative values respectively [(6.7±0.8) points and 66.7%±6.0%], and the values at the last follow-up were significantly lower than those at 1 day postoperation ( P<0.05). The LKAs at 1 day postoperation and the last follow-up (18.1°±4.1° and 19.5°±4.4°) were significantly smaller than that before operation (32.0°±5.2°) ( P<0.05), but there was no significant difference between 1 day postoperation and the last follow-up in LKA ( P>0.05). Conclusion:PVDP is an effective surgical treatment of vsOVCF, because it can relieve pain and improve local kyphosis with satisfactory clinical outcomes.
