One of its primary surgical treatments of tricuspid regurgitation is tricuspid valve biological valve replacement. Catheter tricuspid valve-in-valve implantation is a novel interventional alternative for biological valve failure. The non-invasive lung fluid measuring device remote dielectric sensing (ReDSTM) has been increasingly incorporated into clinical practice as a means of monitoring chronic heart failure in recent years. This report describes the process and outcomes of the first instance of perioperative lung fluid volume evaluation following transcatheter tricuspid valve implantation utilizing ReDSTM technology. The patient has a short-term, substantial increase in postoperative lung fluid volume as compared to baseline.

Donors with a serum sodium concentration of >155 mmol/L are extended criteria donors for liver transplantation (LT). Elevated serum sodium of donors leads to an increased incidence of hepatic dysfunction in the early postoperative period of LT; however, the exact mechanism has not been reported. We constructed a Lewis rat model of 70% hepatic parenchymal area subjected to ischemia-reperfusion (I/R) with hypernatremia and a BRL-3A cell model of hypoxia-reoxygenation (H/R) with high-sodium (HS) culture medium precondition. To determine the degree of injury, biochemical analysis, histological analysis, and oxidative stress and apoptosis detection were performed. We applied specific inhibitors of the epithelial sodium channel (ENaC) and Na⁺/Ca²⁺ exchanger (NCX) in vivo and in vitro to verify their roles in injury. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) levels and the area of hepatic necrosis were significantly elevated in the HS+I/R group. Increased reactive oxygen species (ROS) production, myeloperoxidase (MPO)‍-positive cells, and aggravated cellular apoptosis were detected in the HS+I/R group. The HS+H/R group of BRL-3A cells showed significantly increased cellular apoptosis and ROS production compared to the H/R group. The application of amiloride (Amil), a specific inhibitor of ENaC, reduced ischemia-reperfusion injury (IRI) aggravated by HS both in vivo and in vitro, as evidenced by decreased serum transaminases, inflammatory cytokines, apoptosis, and oxidative stress. SN-6, a specific inhibitor of NCX, had a similar effect to Amil. In summary, hypernatremia aggravates hepatic IRI, which can be attenuated by pharmacological inhibition of ENaC or NCX.

Adolescent idiopathic scoliosis(AIS)is a complex three-dimensional deformity involving coronal,sagittal,and axial planes,with a prevalence that should not be overlooked.With advancements in technology and in-depth research,an increasing number of hospitals and physicians are exploring standardized diagnostic and treatment approaches for AIS.Comprehensive and in-depth understanding is required for AIS,including its etiology,screening and diagnosis,classification,assessment and examination,treatment options,exploration of current focus,and evaluation of quality of life.Such understanding ensures that the diagnostic and treatment are scientific,standardized,and timely.Based on the principles of evidence-based medicine,a consensus on the diagnosis and treatment of AIS is reached after multiple discussions among spinal surgery experts,aiming to provide reference and guidance for clinical practice.

Both cold stress and ischemia-reperfusion injury significantly contribute to poor prognosis after liver transplantation(LT).However,limited animal models incorporating both stimuli hinder the advance-ment of transplant-related research.Here,a simplified and reproducible isolated perfused liver model is established to simulate the stresses experienced by livers maximally during transplantation.We provide a detailed protocol for a straightforward technique that requires 20-30 min for harvesting,24-48 h for static cold storage(SCS),and 2 h for normothermic machine perfusion(NMP)to induce LT-like stresses in the liver.Hepatic injury from SCS and NMP(LT-like stresses)is evaluated using three types of parameters.The pH values and hepatic enzyme levels of cold preservation solutions and perfusate serve as dynamic indicators of hepatic injury.Bile production and portal venous resistance directly reflect liver function,whereas pathological analysis visually illustrates the location and extent of injury.This animal model eliminates the influence of hemodynamic and immune factors,yielding highly reproducible results,and is strongly recommended as a standardized animal model for inducing LT-like stresses.

Objective To observe the clinical efficacy of therapy focusing on regulating spleen and stomach for the treatment of acoustic hypersensitivity(AH),which also named as auditory hyperaesthesia,and to explore the relevant factors influencing the efficacy.Methods From January 2018 to December 2023,the patients admitted to the outpatient department of otolaryngology-head and neck surgery of the First Affiliated Hospital of Guangzhou University of Chinese Medicine and diagnosed as AH with complete medical data were included as study subjects.Follow-up through telephone or network was carried out for those patients who with uncertain prognosis.The changes in the pre-and post-treatment scores of Indicators of Acoustic Hypersensitivity Severity(IAHS)were used as the reference index for efficacy evaluation,and the cure rate and effective rate were used as the efficacy analysis indexes for statistical analysis.And then the efficacy of traditional Chinese medicine(TCM)medical care combined with health care focusing on regulating spleen and stomach for the treatment of AH was evaluated.Furthermore,multivariate logistic regression was used to explore the relevant factors influencing the efficacy of AH.Results A total of 298 cases of AH patients meeting the inclusion criteria were collected,among which 151 cases(50.67%)were cured,22 cases(7.38%)were markedly effective,75 cases(25.17%)were effective,and 50 cases(16.78%)were ineffective,with a total effective rate of 83.22%(248/298).The univariate analysis results showed that eight factors(including post-treatment lifestyle score,range of lifestyle adjustment,severity of AH,duration of the disease,presence of tinnitus,presence of hearing drop,presence of vertigo,and age)had an influence on the efficacy,and the differences were statistically significant(P<0.05 or P<0.01).However,the factors of gender,occupation,education level,and history of noise exposure had no influence on the efficacy(P>0.05).The multivariate binary logistic regression analysis showed that five factors,namely post-treatment lifestyle score,range of lifestyle adjustment,severity of AH,presence of vertigo and duration of the disease,had a significant correlation with the cure rate of AH(P<0.05 or P<0.01),and four factors,namely post-treatment lifestyle score,severity of AH,range of lifestyle adjustment and age,had a significant correlation with the effective rate of AH(P<0.05 or P<0.01).Conclusion The method of TCM medical care and health care focusing on regulating spleen and stomach exerts a better efficacy for AH patients.And the lifestyle,severity of AH,duration of the disease,age,and presence of vertigo are the relevant factors affecting the outcomes,which is worthy of further in-depth study.

ObjectiveTo demonstrate the long-term effect of Yishi Therapy for primary tinnitus and analyze the factors affecting the effectiveness. MethodsWe conducted long-term follow-ups of primary tinnitus cases treated with Yishi Therapy during 1 January 2017 to 30 June 2023 by face-to-face， online and telephone between 1 July 2023 and 31 January 2024， to understand the final regression of primary tinnitus and lifestyle changes. We retrospectively analysed the basic data of patients before treatment， and statistically analysed the recovery rate and overall effective rate of tinnitus treated by the Yishi Therapy， and the factors affecting the effectiveness such as lifestyle， age， duration of disease， gender， tinnitus location， severity of tinnitus， accompanying symptoms and complications on the overall effective rate. ResultsA total of 496 cases of primary tinnitus completed follow-ups successfully， and the total Tinnitus Evaluation Questionnaire （TEQ） at follow-up was significantly lower than that before treatment （P＜0.001）. Among the 496 cases， 101 （20.36%） cases cured， 189 （38.10%） cases showed significant improvement， 116 （23.39%） cases were effective， 90 （18.15%） cases were ineffective， and the overall effect rate was 81.85% （406/496）. At follow-up， the score of lifestyle was higher than that before treatment （P＜0.001）. Grouped by the score of lifestyle at follow-up， the effective rates of better lifestyle group and poor lifestyle group were 97.53% （237/243） and 66.80% （169/253）， respectively， with statistical significance （P＜0.001）. Grouped by the mean value of the difference in lifestyle scores before and after treatment， the effective rates of the group with greater lifestyle adjustment and the group with smaller adjustment were 97.55% （239/245） and 66.53% （167/251）， respectively， and the differences were statistically significant （P＜0.001）. Binary logistic regression showed that the better lifestyle， the greater lifestyle adjustment and the severity of tinnitus were positively correlated with the total effective rate of tinnitus （P＜0.001）， while older and hearing loss were negatively correlated with the total effective rate of tinnitus （P＜0.05）. ConclusionYishi Therapy on primary tinnitus shows good long-term effect， lifestyle， severity of tinnitus， hearing loss or not， age are the relevant factors affecting the efficacy of tinnitus， lifestyle is the main factor affecting clinical efficacy.

Objective To explore the difference of serum inflammatory factors in patients with first episode schizo-phrenia,patients with relapse episode schizophrenia and healthy people,and the correlation between serum inflam-matory factors with negative symptoms in patients with schizophrenia,so as to provide reference for clinical inter-vention.Methods A total of 86 patients with first episode schizophrenia(first episode group),80 patients with re-lapse episode schizophrenia(relapse episode group)and 82 healthy people(control group)were included in the study.The difference of serum inflammatory factors among the three groups and the correlation between serum inflammatory factors with negative symptoms were analyzed.Results There were significant differences in serum interleukin(IL)-1β and IL-16 levels among the three groups(P<0.05).The analysis and comparison between the two groups showed that the serum IL-1β in first episode group was significantly higher than that in relapse episode group and control group(P<0.05),serum IL-16 in first episode group and relapse episode group was significantly higher than that in control group(P<0.05).Serum IL-1β was negatively correlated with PANSS general psycho-pathological scale factor score in first episode group(P<0.05),and serum IL-16 was positively correlated with PANSS negative symptom scale factor score in relapse episode group(P<0.05).IL-16 level might be an inde-pendent risk factor affecting the onset of first episode group and relapse episode group(P<0.05).Conclusion There are differences in serum levels of IL-1β and IL-16 between patients with schizophrenia and healthy people.Serum IL-16 levels in patients with relapse episode schizophrenia are associated with negative symptoms.IL-16 lev-el may be an independent risk factor for schizophrenia.

Astrocytes are the largest glial population in the mammalian brain. However, we have a minimal understanding of astrocyte development, especially fate specification in different regions of the brain. Through lineage tracing of the progenitors of the third ventricle (3V) wall via in-utero electroporation in the embryonic mouse brain, we show the fate specification and migration pattern of astrocytes derived from radial glia along the 3V wall. Unexpectedly, radial glia located in different regions along the 3V wall of the diencephalon produce distinct cell types: radial glia in the upper region produce astrocytes and those in the lower region produce neurons in the diencephalon. With genetic fate mapping analysis, we reveal that the first population of astrocytes appears along the zona incerta in the diencephalon. Astrogenesis occurs at an early time point in the dorsal region relative to that in the ventral region of the developing diencephalon. With transcriptomic analysis of the region-specific 3V wall and lateral ventricle (LV) wall, we identified cohorts of differentially-expressed genes in the dorsal 3V wall compared to the ventral 3V wall and LV wall that may regulate astrogenesis in the dorsal diencephalon. Together, these results demonstrate that the generation of astrocytes shows a spatiotemporal pattern in the developing mouse diencephalon.

BACKGROUND:There is no consensus on the optimal bone tunnel position in the lateral clavicle,which guides coracoclavicular ligament reconstruction.Postoperative complications such as enlargement of the lateral clavicle bone tunnel,bone osteolysis,clavicle fracture,and failure of internal fixation are likely to occur.Bone mass density plays an important role in the strength and stability of endophytic fixation.Regional differences in the bone mass density of the distal clavicle should not be overlooked in the repair and reconstruction of acromioclavicular dislocation.Currently,there are no quantitative clinical studies in humans regarding the bone mass density of the distal clavicle. OBJECTIVE:To measure the magnitude of bone mass density in different regions of the distal clavicle by quantitative CT to provide a reference for surgeons to repair and reconstruct the coracoclavicular ligament. METHODS:101 patients undergoing quantitative CT checking in Fuyang People's Hospital Affiliated to Anhui Medical University from October to December 2022 were enrolled,from which 1 616 samples of subdivisional bone mass density of the distal clavicle were measured.For each of the quantitative CT samples,firstly,the distal clavicle was divided medially to laterally into the following four regions:conical nodal region(region A),inter-nodal region(region B),oblique crest region(region C)and distal clavicular region(region D).Secondly,each region was divided into the first half and the second half to determine eight subdivisions,then setting semiautomatic region of interest(ROI)in each subdivision:(ROI A1,A2,B1,B2,C1,C2,D1,and D2).Thirdly,each quantitative CT scan was transferred to the quantitative CT pro analysis workstation,and cancellous bone mass density was measured in the distal clavicle ROI.Finally,the clavicular cortex was avoided when measuring. RESULTS AND CONCLUSION:(1)There was no statistically significant difference in bone mineral density on the different sides of the shoulder(P＞0.05).(2)The analysis of bone mineral density in eight sub-areas of the distal clavicle A1,A2,B1,B2,C1,C2,D1,and D2 showed statistically significant differences(P＜0.05).It could be considered that there were differences in bone mineral density in different areas of the distal clavicle.After pairwise comparison,there was no statistically significant difference in bone mineral density between A1 and A2,D1 and D2,A2 and B1(P＞0.05),and there was a statistically significant difference in bone mineral density between the other sub-areas(P＜0.05).(3)The bone mineral density in the region A2 of the anatomical insertion of the conical ligament was significantly higher than that in the inter-nodular area(region B)(P＜0.05).The bone mineral density in the region A1 was higher than that in the region A2,but the difference was not statistically significant(P＞0.05).The bone mineral density in the region C1 of the anatomical insertion of the trapezium ligament was higher than that in regions C2,D1 and D2,and the bone mineral density in the inter-nodular area(region B)was significantly higher than that in regions C and D(P＜0.05).(4)These results have suggested that there are differences in bone mass density in different regions of the distal clavicle;regional differences in bone mass density in the distal clavicle during repair and reconstruction of acromioclavicular dislocation cannot be ignored.Consideration should be given not only to biomechanical factors but also to the placement of implants or bone tunnels in regions of higher bone mass density,which could improve the strength and stability of implant fixation and reduce the risk of complications such as bone tunnel enlargement,osteolysis,fracture and implant failure.
