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.

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.

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.

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.

Objective To investigate the effects of perineal massage combined with hip joint exercise on the outcome of delivery and mental resilience of primipara.Methods 90 pregnant women in the third trimester(after 36 weeks)who obtained the knowledge about perineal massage from midwife clinic were randomly divided into two groups with 45 cases each.The control group received regular antenatal examination and family self-exercise;the experimental group received perineal massage and hip joint training combined treatment.The delivery outcome,birth experience and maternal mental resilience of the two groups were compared.Results the number of vaginal delivery in the experimental group were higher than that in the control group(P<0.05);the second stage of labor was significantly shorter than that of the control group(P<0.05);the perineal integrity rate was higher than that of the control group(P<0.05);the scores of all dimensions in delivery experience questionnaire were higher than that of the control group(P<0.05);the scores of all dimensions in maternal mental resilience were higher than those of the control group(P<0.05)after intervention.Conclusion The perineal massage which conducted by midwives combined with hip movement can effectively improve the quality of delivery,relieve the negative emotions of pregnant women,improve the psychological elasticity level of pregnant women,and improve the delivery outcomes.

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.

Objective To explore the difference in left ventricular reverse remodeling(LVRR)between coarctation of aorta(CoA)complicated by bicuspid aortic valve(BAV)and that by tricuspid aortic valve(TAV)after percutaneous intervention.Methods The clinical data on 47 patients undergoing percutaneous balloon dila-tion and stent implantation due to CoA in Fuwai Hospital of Chinese Academy of Medical Sciences from January 2014 to December 2021 were retrospectively analyzed.According to the preoperative imaging data,there were 18 patients with BAVA and 29 with TAV.The results of echocardiography before and one year after the procedure were compared.Results CoA Vmax,CoA PG,LVEDd,LVEDdi,LVM and LVMI were significantly improved in CoA patients one year after percutaneous intervention,and 23.4%of the patients developed left ventricular reverse remodeling.AV Vmax,AV PG and LVEDdi in the patients with BAV were higher than those in the TAV group(P = 0.005 and P = 0.007;P = 0.03),and the rate of left ventricular reverse remodeling in BAV patients was lower than that in TAV patients,but there was no statistical significance.Multivariate analysis did not find any influence factors affecting left ventricular reverse remodeling one year after the procedure.Conclusions Part of the CoA patients develops left ventricular remodeling reversal one year after percutaneous intervention.LVRR in patients with BAV is lower than that in those with TAV,which still needs further clinical research.

Objective:To investigate the perioperative impact of closure of mesenteric fissure in laparoscopic right hemicolectomy.Methods:The prospective randomized controlled trial was conducted. The clinical data of 320 patients who underwent laparoscopic right hemicolectomy in 11 medical centers, including The First Affiliated Hospital of China Medical University et al, from November 2022 to August 2023 were selected. Based on block randomization, patients were alloca-ted into the mesenteric fissure non-closure group and the mesenteric fissure closure group. Observa-tion indicators: (1) grouping of the enrolled patients; (2) intraoperative conditions; (3) postopera-tive conditions. Measurement data with skewed distribution were represented as M( Q1, Q3) and com-parison between groups was conducted using the Mann-Whitney U test. Count data were represen-ted as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher's exact probability. Comparison of ordinal data was conducted using the rank sum test. Comparison of visual analog scores was analyzed using generalized estimating equations. Results:(1) Grouping of the enrolled patients. A total of 320 patients with colon cancer were screened for eligibility, including 156 males and 164 females, aged 68(59,73)years. All the 320 patients were allocated into the mesenteric fissure non-closure group with 164 cases and the mesenteric fissure closure group with 156 cases. There was no significant difference in the age, body mass index, American Society of Anesthesiologist score, maximum tumor diameter, anastomosis location, anastomosis method, surgical approach, range of lymph node dissection, tumor staging between the two groups ( P>0.05) and there was a significant difference in the sex between them ( P<0.05). (2) Intraoperative conditions. There was no significant difference between the mesenteric fissure closure group and the mesenteric fissure non-closure group in the volume of intraoperative blood loss, operation time, conversion to laparotomy, intraoperative complication ( P>0.05). Three patients in the mesenteric fissure non-closure group were converted to laparotomy. One patient in the mesenteric fissure closure group was converted to laparotomy, and 2 cases with intraoperative complication were mesenteric hematoma. (3) Postoperative conditions. There was no significant difference between the mesenteric fissure non-closure group and the mesenteric fissure closure group in the overall postoperative complications ( χ2=0.28, P>0.05). There was no significant difference in the occurrence of postoperative intestinal obstruction, abdominal distension, ascites, pleural effusion, gastric paralysis, anastomotic bleeding, anastomotic leakage, or surgical wound infection between the two groups ( P>0.05). There was no significant difference between the two groups in the reoperation, postoperative gastric tube replacement. There was no significant differ-ence in time to postoperative first flatus, time to postoperative initial liquid food intake, time to post-operative resumption of bowel movements, duration of postoperative hospital stay, total hospital expenses between the two groups ( Z=-0.01, 0.43, 1.04, -0.54, -0.36, P>0.05). One patient in the mesenteric fissure non-closure group received reoperation. No perioperative internal hernia or death occurred in either group. The visual analog score decreased with time in both groups. There was no significant difference in the visual analog score between the mesenteric fissure closure group and the mesenteric fissure non-closure group [ β=-0.20(-0.53,0.13), P>0.05]. Conclusion:Compared with closure of mesenteric fissure, non-closure of mesenteric fissure during laparoscopic right hemi-colectomy dose not increase perioperative complications or postoperative management risk.

Objective To investigate the plasma level of interleukin-31(IL-31)in patients with pulmonary arterial hypertension(PAH)and its clinical relevance.Methods The patients who were diagnosed as PAH in Zhongshan Hospital,Fudan University from January 1,2021 to December 30,2023(PAH group)and the healthy people in the same period(control group)were selected.The clinical data and follow-up records were collected.Plasma levels of IL-31,IL-1β,IL-6,IL-10,IL-12p70,monocyte chemoattractant protein-1(MCP-1),tumor necrosis factor-α(TNF-α)and transforming growth factor-β1(TGF-β1)were detected by enzyme-linked immunosorbent assay(ELISA).Pearson correlation test was used to evaluate the correlations between IL-31 and right cardiac catheterization parameters,echocardiography parameters and blood indices in patients with PAH.Cox proportional hazard model was used to analyze the prognostic factors of patients in PAH group.Results A total of 50 patients with PAH and 22 healthy controls were included.There was no significant difference in age,gender,body mass index and left ventricular ejection fraction between the two groups.Compared with the control group,the plasma level of IL-31 in the PAH group was significantly higher(168.82[149.14,177.26]pg/mL vs 152.76[145.58,159.41]pg/mL,P=0.001).Pearson correlation test showed that the plasma level of IL-31 in PAH patient was positively correlated with mean pulmonary artery pressure(r=0.652,P＜0.001)and pulmonary vascular resistance(r=0.651,P＜0.001),but was negatively correlated with tricuspid annular plane systolic excursion(r=-0.496,P＜0.001).Cox proportional hazard model showed that higher plasma level of IL-31 was an independent predictor of readmission for heart failure/all-cause mortality in patients with PAH(HR=1.130,95％CI 1.052-1.214,P=0.001).Conclusions Plasma level of IL-31 may be significantly increased in patients with PAH and be positively correlated with the severity of PAH,and elevated level of IL-31 is predictive of poor prognosis in PAH patients.
