Objective To explore the value of combined ultrasound parameters, including the hepatorenal index (HRI) and renal resistance index (RRI), with cystatin C (CysC) in monitoring early acute kidney injury (AKI) after liver transplantation. Methods Perioperative data from 121 liver transplant recipients who received organs from donation after brain death were collected. The HRI and RRI of the recipients were measured on postoperative days 1-7 and at 1 month, and the CysC levels were measured on postoperative day 1. The recipients were divided into the AKI group (n=53) and the non-AKI group (n=68) based on whether AKI occurred within 7 days after operation. The data of the two groups were compared, and the ultrasound parameters before and after recovery in the AKI group were analyzed. The value of combined HRI, RRI and CysC in monitoring AKI was also analyzed. Results AKI occurred in 53 recipients, with an incidence rate of 43.8%, including 30 cases of stage 1, 18 cases of stage 2, and 5 cases of stage 3. Among them, 49 cases occurred on postoperative day 1, and 4 cases occurred on postoperative day 2. Of these, 43 cases recovered within 7 days after surgery, 8 cases recovered within 2 months after surgery, 1 case was lost to follow-up, and 1 case received renal replacement therapy. The body mass index and preoperative CysC levels were higher in the AKI group than in the non-AKI group, and the operative time was longer in the AKI group than in the non-AKI group (all P < 0.05). The HRI on postoperative day 1 was lower in the AKI group than in the non-AKI group, while the RRI and CysC levels were higher (all P < 0.05). When AKI occurred, the HRI was lower than the baseline level, and the RRI was higher than the baseline level. As AKI recovered, the HRI gradually increased, and the RRI gradually decreased. The receiver operating characteristic curve analysis showed that the sensitivity and specificity of HRI ≤ 1.12 for predicting AKI were 0.623 and 0.878, respectively, with an area under the curve (AUC) of 0.801. The sensitivity and specificity of RRI ≥ 0.65 for predicting AKI were 0.878 and 0.676, respectively, with an AUC of 0.825. The sensitivity and specificity of CysC ≥ 1.38 mg/L for predicting AKI were 0.736 and 0.882, respectively, with an AUC of 0.851 (all P<0.01). The combination of HRI and CysC (AUC=0.897, P<0.01), RRI and CysC (AUC=0.910, P<0.01), and all three parameters combined (AUC=0.934, P<0.01) were more effective than using each parameter alone. Conclusions HRI and RRI may be used to monitor the occurrence and recovery of early AKI after liver transplantation. The combination of these two parameters with CysC has a high application value in monitoring early AKI after liver transplantation.

Peri-implant keratinized mucosa (PIKM) augmentation refers to surgical procedures aimed at increasing the width of PIKM. Consensus reports emphasize the necessity of maintaining a minimum width of PIKM to ensure long-term peri-implant health. Currently, several surgical techniques have been validated for their effectiveness in increasing PIKM. However, the selection and application of PIKM augmentation methods may present challenges for dental practitioners due to heterogeneity in surgical techniques, variations in clinical scenarios, and anatomical differences. Therefore, clear guidelines and considerations for PIKM augmentation are needed. This expert consensus focuses on the commonly employed surgical techniques for PIKM augmentation and the factors influencing their selection at second-stage surgery. It aims to establish a standardized framework for assessing, planning, and executing PIKM augmentation procedures, with the goal of offering evidence-based guidance to enhance the predictability and success of PIKM augmentation.

Diabetes has long been considered a risk factor in implant therapy and impaired wound healing in soft and hard oral tissues. Magnesium has been proved to promote bone healing under normal conditions. Here, we elucidate the mechanism by which Mg2+ promotes angiogenesis and osseointegration in diabetic status. We generated a diabetic mice model and demonstrated the alveolar bone healing was compromised, with significantly decreased angiogenesis. We then developed Mg-coating implants with hydrothermal synthesis. These implants successfully improved the vascularization and osseointegration in diabetic status. Mechanically, Mg2+ promoted the degradation of Kelch-like ECH-associated protein 1 (Keap1) and the nucleation of nuclear factor erythroid 2-related factor 2 (Nrf2) by up-regulating the expression of sestrin 2 (SESN2) in endothelial cells, thus reducing the elevated levels of oxidative stress in mitochondria and relieving endothelial cell dysfunction under hyperglycemia. Altogether, our data suggested that Mg2+ promoted angiogenesis and osseointegration in diabetic mice by regulating endothelial mitochondrial metabolism.

Objective:Exploring the value of contrast enhanced ultrasound (CEUS) plus transient elastography in evaluating donor livers for C-I donors and predicting the occurrence of early allograft dysfunction (EAD).Methods:Between September 1, 2022 and August 31, 2023, the relevant clinical data were retrospectively reviewed for 75 pairs of donors and recipients. Based upon whether or not there was a postoperative onset of EAD, the recipients were assigned into two groups of EAD (16 cases) and non-EAD (59 cases) . All donors were examined by contrast-enhanced ultrasonography and FibroScan. QLAB analysis software was utilized for analyzing the results of contrast-enhanced ultrasound. Liver parenchyma at 3 cm below liver capsule was selected as a region of interest for plotting the time-intensity curve (TIC) . And the contrast-enhanced ultrasonic parameters of two groups were recorded. FibroScan transient elastography instrument was employed for quantifying liver stiffness 12 times in right lobe of donor liver and recording quantitative parameters of liver stiffness measurement (LSM) and controlled attenuation parameter (CAP) .Results:Inter-group comparison of gender, age, body mass index (BMI) and ICU length of stay showed no statistically significant differences ( P>0. 05) . However, significant differences existed in the levels of platelet [ (122. 44±85. 82) vs (197. 22± 140. 93) ×10 9/L]and cholinesterase [ (3 473. 44±1 368. 54) vs (4 252. 93±1 365. 37) U/L]within the first 24h pre-operation ( P=0. 047, P=0. 047) . Peak intensity (PKI) and area under the curve (AUC) were lower in EAD group than those in non-EAD group [ (16. 44±4. 70) dB vs 19. 85±4. 39 dB, P=0. 009; (1 366. 76±508. 10) dB·s vs (1 675. 23±498. 77) dB·s, P=0. 014]. There were statistically significant differences ( P=0. 009, P=0. 032) . Arterial-portal arrival interval (APAI) and LSM were higher in EAD group than those in non-EAD group[6. 50 (5. 00, 10.75) s vs 5. 00 (4. 00, 7. 00) s, P =0. 24; 8. 60 (6. 32, 11. 65) kPa vs 6. 10 (5. 40, 7. 90) kPa, P=0. 014]. Receiver operating characteristic (ROC) curve analysis revealed that PKI, AUC, APAI and LSM had AUC values of 0. 703, 0. 664, 0. 683 and 0. 702, respectively in predicting postoperative EAD. And combined prediction of EAD occurrence based upon these parameters had an AUC of 0. 776, a Youden index of 0. 508 with cutoff values, sensitivity and specificity of 0. 800, 0. 813 and 0. 695 respectively. Spearman' s correlation analysis revealed a negative correlation between APAI and AUC values ( r= -0. 404, P<0. 001) . Conclusions:The combination of CEUS and transient elastography can comprehensively evaluate the status of microcirculatory perfusion, fibrosis and steatosis of liver grafts from brain death donors. It offers a great predictive value for postoperative occurrence of EAD.

Objective To develop a nomogram model based on the clinical features and the radiomics texture analysis of multimodal magnetic resonance imaging(MRI),so as to predict the tumor response in patients with advanced hepatocellular carcinoma(HCC)3 months after receiving transcatheter arterial chemoembolization(TACE).Methods A total of 105 patients with advanced HCC,whose diagnosis was pathologically-confirmed at the Suzhou Municipal Ninth People's Hospital between January 2017 and December 2021,were enrolled in this study.The patients were randomly divided into training group(n=63)and verification group(n=42).Before chemotherapy,T1WI,T2WI,dynamic contrast-enhanced(DCE)scan,and diffusion-weighted imaging(DWI)were performed by using a 3.0T MRI scanner.A.K.software was used to extract the texture.Three months after chemotherapy,according to the modified Response Evaluation Criteria in Solid Tumors(mRECIST)the patients were divided into response group(n=63)and non-response group(n=42).Results Compared with the response group,in the non-response group the percentage of Child-Pugh grade B and BCLC stage C was obviously higher and the serum alpha fetoprotein(AFP)level was remarkably elevated(P<0.05).A.K.software extracted 396 MRI texture features,and LASSO regression analysis screened out 6 optimal predictors.The radiation score(Rad-score)was calculated by ROC.The AUC of Rad-score for predicting tumor non-response after TACE by ROC in the training group and verification group were 0.842 and 0.803 respectively.Multivariate logistic regression model analysis showed that AFP≥50 ng/mL(OR=1.568,95%CI=1.234-1.902,P=0.003),Child-Pugh grade B(OR=1.754,95%CI=1.326-2.021,P=0.001),BCLC stage C(OR=1.847,95%CI=1.412-2.232,P=0.001)and Rad-score(OR=2.023,95%CI=1.569-2.457,P<0.001)were the independent risk factors for tumor non-response.Clinico-radiomics combination had the highest AUC value for predicting tumor non-response.The correction curve showed that the nomogram model had a good agreement.Conclusion The quantitative score of radiomics texture analysis of multimodal MRI has a certain value in predicting tumor non-response in advanced HCC patients 3 months after TACE,and the nomogram model,which is constructed if combined with clinical factors,carries good practical potential.(J Intervent Radiol,2024,32:63-68)
