ObjectiveTo investigate the influence of entecavir （ETV） versus tenofovir alafenamide fumarate （TAF） on renal function in previously untreated patients with chronic hepatitis B （CHB）. MethodsA retrospective analysis was performed for the clinical data of 167 previously untreated CHB patients who received ETV or TAF treatment for at least 48 weeks at the outpatient service of Department of Infectious Diseases in The First Affiliated Hospital of Nanchang University from September 2019 to November 2023， and according to the antiviral drug used， they were divided into ETV group with 117 patients and TAF group with 50 patients. In order to balance baseline clinical data， propensity score matching （PSM） was used for matching and analysis at a ratio of 2∶1， and the two groups were compared in terms of estimated glomerular filtration rate （eGFR） and the incidence rate of abnormal renal function at week 48. According to eGFR at week 48， the patients were divided into normal renal function group and abnormal renal function group. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. The multivariate Logistic regression analysis was used to investigate the influencing factors for abnormal renal function， and the receiver operating characteristic （ROC） curve was used to assess the performance of each indicator in predicting abnormal renal function. The Kaplan-Meier method was used to analyze the cumulative incidence rate of abnormal renal function， and the log-rank test was used for comparison. The analysis of variance with repeated measures was used to compare the dynamic changes of eGFR during antiviral therapy in CHB patients. ResultsAfter PSM matching， there were 100 patients in the ETV group and 50 patients in the TAF group. There were no significant differences in baseline clinical data between the ETV group and the TAF group （all P>0.05）， with an eGFR level of 112.29±9.92 mL/min/1.73 m² in the ETV group and 114.72±12.15 mL/min/1.73 m² in the TAF group. There was a reduction in eGFR from baseline to week 48 in both groups， and compared with the TAF group at week 48， the ETV group had a significantly lower eGFR （106.42±14.12 mL/min/1.73 m² vs 112.25±13.44 mL/min/1.73 m²， t=-2.422， P=0.017） and a significantly higher incidence rate of abnormal renal function （17.00% vs 4.00%， χ²=5.092， P=0.024）. After the patients were divided into normal renal function group with 131 patients and abnormal renal function group with 19 patients， the univariate analysis showed that there were significant differences between the two groups in age （Z=-2.039， P=0.041）， treatment drug （ETV/TAF） （χ²=5.092， P=0.024）， and baseline eGFR level （t=4.023， P<0.001）， and the multivariate Logistic regression analysis showed that baseline eGFR （odds ratio ［OR］=0.896， 95% confidence interval ［CI］： 0.841 — 0.955， P<0.001） and treatment drug （OR=5.589， 95%CI： 1.136 — 27.492， P=0.034） were independent influencing factors for abnormal renal function. Baseline eGFR had an area under the ROC curve of 0.781 in predicting abnormal renal function in CHB patients， with a cut-off value of 105.24 mL/min/1.73 m²， a sensitivity of 73.68%， and a specificity of 82.44%. The Kaplan-Meier curve analysis showed that the patients with baseline eGFR≤105.24 mL/min/1.73 m² had a significantly higher cumulative incidence rate of abnormal renal function than those with baseline eGFR>105.24 mL/min/1.73 m² （χ²=22.330， P<0.001）， and the ETV group had a significantly higher cumulative incidence rate of abnormal renal function than the TAF group （χ²=4.961， P=0.026）. With the initiation of antiviral therapy， both the ETV group and the TAF group had a significant reduction in eGFR （F=5.259， P<0.001）， but the ETV group only had a significant lower level of eGFR than the TAF group at week 48 （t=-2.422， P=0.017）； both the baseline eGFR≤105.24 mL/min/1.73 m² group and the baseline eGFR>105.24 mL/min/1.73 m² group had a significant reduction in eGFR （F=5.712， P<0.001）， and there was a significant difference in eGFR between the two groups at baseline and weeks 12， 24， 36， and 48 （t=-13.927， -9.780， -8.835， -9.489， and -8.953， all P<0.001）. ConclusionFor CHB patients initially treated with ETV or TAF， ETV antiviral therapy has a higher risk of renal injury than TAF therapy at week 48.

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.

ObjectiveTo investigate the protective effect of the extract of Liuwei Dihuangwan （LW） on mitochondrial damage in the Alzheimer's disease （AD） model of Caenorhabditis elegans （C. elegans）. MethodC. elegans transfected with human β-amyloid protein （Aβ） _1-42 gene was used as an AD model. The rats were divided into blank group， model group， metformin group （50 mmol·L^-1）， and low， medium， and high dose （1.04， 2.08， 4.16 g·kg^-1） LW groups. Behavioral methods were used to observe the sensitivity of 5-hydroxytryptamine （5-HT） in nematodes. Western blot was used to detect the expression of Aβ in nematodes. Total ATP content in nematodes was detected by the adenine nucleoside triphosphate （ATP） kit， and mitochondrial membrane potential was detected by the JC-1 method. In addition， the mRNA expression of Aβ expression gene （Amy-1）， superoxide dismutase-1 （SOD-1）， mitochondrial transcription factor A homologous gene-5 （HMG-5）， mitochondrial power-associated protein 1 （DRP1）， and mitochondrial mitoprotein 1 （FIS1） was detected by real-time fluorescence quantitative polymerase chain reaction （RT-PCR）. ResultThe extract of LW could reduce the hypersensitivity of the AD model of nematodes to exogenous 5-HT （P<0.05） and delay the AD-like pathological characteristics of hypersensitivity to exogenous 5-HT caused by toxicity from overexpression of Aβ in neurons of the AD model of nematodes. Compared with the blank group， in the model group， the mRNA expression of Aβ protein and Amy-1 increased （P<0.01）， and the mRNA expression of SOD-1 and HMG-5 decreased （P<0.01）. The mRNA expression of DRP1 and FIS1 increased （P<0.01）， and the level of mitochondrial membrane potential decreased （P<0.05）. The content of ATP decreased （P<0.01）. Compared with the model group， in the positive medicine group and medium and high dose LW groups， the mRNA expression of Aβ protein and Amy-1 decreased （P<0.05，P<0.01）， and the mRNA expression of SOD-1 and HMG-5 increased （P<0.01）. The mRNA expression of DRP1 decreased （P<0.05，P<0.01）， and that of FIS1 decreased （P<0.01）. The level of mitochondrial membrane potential increased （P<0.01）， and the content of ATP increased （P<0.05，P<0.01）. ConclusionThe extract of LW may enhance the antioxidant ability of mitochondria， protect mitochondrial DNA， reduce the fragmentation of mitochondrial division， repair the damaged mitochondria， adjust the mitochondrial membrane potential， restore the level of neuronal ATP， and reduce the neuronal damage caused by Aβ deposition.

ObjectiveTo investigate the differences in clinical features and mortality rate between native patients with chronic liver failure （CHF） and migrated patients with CHF after treatment with double plasma molecular adsorption system （DPMAS） in high-altitude areas. MethodsA total of 63 patients with CHF who received DPMAS treatment in the intensive care unit of General Hospital of Tibet Military Command from January 2016 to December 2021 were enrolled， and according to their history of residence in high-altitude areas， they were divided into native group with 29 patients and migrated group with 34 patients. The two groups were compared in terms of baseline data and clinical features before and after DPMAS treatment. The independent-samples t test was used for comparison of normally distributed continuous data between groups， and the paired t-test was used for comparison before and after treatment within each group； the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups， and the Wilcoxon signed rank sum test was used for comparison before and after treatment within each group； the chi-square test was used for comparison of categorical data between groups. The Kaplan-Meier method was used to plot survival curves， and the Log-rank test was used for comparison of the risk of death. ResultsCompared with the native group， the migrated group had a significantly higher proportion of Chinese Han patients （χ²=41.729， P<0.001）， and compared with the migrated group， the native group had a significantly longer duration of the most recent continuous residence in high-altitude areas （Z=3.364， P<0.001）. Compared with the native group， the migrated group had significantly higher MELD score and incidence rates of hepatic encephalopathy， hepatorenal syndrome， and gastrointestinal bleeding （Z=2.318， χ²=6.903， 5.154， and 6.262， all P<0.05）. Both groups had significant changes in platelet count （PLT）， hemoglobin count （HGB）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， albumin， total bilirubin （TBil）， direct bilirubin （DBil）， lactate dehydrogenase （LDH）， creatinine （Cr）， and international normalized ratio （INR） after DPMAS treatment （all P<0.05）. Before DPMAS treatment， compared with the native group， the migrated group had significantly higher levels of ALT， AST， TBil， DBil， LDH， Cr， BUN， and INR （all P<0.05） and a significantly lower level of HGB （P<0.05）； after DPMAS treatment， compared with the native group， the migrated group had significantly greater reductions in PLT and HGB （both P<0.05） and still significantly higher levels of ALT， AST， TBil， DBil， LDH， BUN， and INR （all P<0.05）. The 60-day mortality rate of patients after DPMAS treatment was 52.5% （95% confidence interval ［CI］： 41.7 — 63.8） in the native group and 81.3% （95%CI： 77.9 — 85.6） in the migrated group. Compared with the native group （hazard ratio ［HR］=0.47， 95%CI： 0.23 — 0.95）， the migrated group had a significant increase in the risk of death on day 60 （HR=2.14， 95%CI： 1.06 — 4.32， P=0.039）. ConclusionCompared with the native patients with CHF in high-altitude areas， migrated patients have a higher degree of liver impairment， a lower degree of improvement in liver function after DPMAS treatment， and a higher mortality rate. Clinical medical staff need to pay more attention to migrated patients with CHF， so as to improve their survival rates.

ObjectiveTo investigate the mechanism by which Liuwei Dihuang Erzhiwan combination inhibit the lung metastasis of spontaneous breast cancer in mice by regulating the recruitment of myeloid-derived suppressor cells （MDSCs）. MethodThree hundred and eighty SPF-grade 10-month-old female breeders of Kunming mouse were palpated at the mammary gland site once every 3 days. Mice that have not had a lump touched after being raised for 6 months are used as control group. After tumor development， the mice were randomized into model， positive control （paclitaxel， intraperitoneal injection at 0.01 g·kg^-1 every other day for 22 d）， Liuwei Dihuangwan （0.65 g·kg^-1·d^-1 by gavage）， Erzhiwan （5.41 g·kg^-1·d^-1 by gavage）， and Liuwei Dihuang Erzhiwan combination （6.05 g·kg^-1·d^-1 by gavage） groups. The mice were euthanised when the tumor reached a diameter of about 15 mm， and the tumor and lung tissues were collected. The survival time， tumor mass， and lung metastasis rate of tumor-bearing mice were recorded. Hematoxylin-eosin （HE） staining was used to observe the histopathological and morphological changes of mouse tumor and lung tissues. Immunofluorescence （IF） was used to detect the distribution of MDSCs in tissues of mice in each group by double-staining of MDSCs cells with lymphocyte antigen 6 complex site G6D （Ly6G） and CD11 antigen-like family member B （CD11b）. Western blot was employed to determine the protein levels of matrix metalloproteinase-9 （MMP-9）， transforming growth factor-β （TGF-β）， zinc finger transcription factor 1 （Snail1）， and E-cadherin in the tumor tissue and CC motif chemokine 9 （CCL9） and CC motif chemokine receptor 1 （CCR1） in the lung tissue. ResultDuring the modelling period， the paclitaxel group and Chinese medicine intervention groups had longer median number of days of survival and lower tumor weight， lung metastasis rate， and lung nodule than the model group （P<0.05， P<0.01）. HE staining showed an increase in tumor cell necrosis in the paclitaxel group and the Liuwei Dihuang Erzhiwan combination group. The paclitaxel group and Chinese medicine intervention groups had lower fluorescence intensity of MDSCs in the tumor tissue than the model group （P<0.05， P<0.01）. Compared with the normal control group， the model group showed increased fluorescence intensity of MDSCs in the metastatic lung tissue （P<0.01）， which， however， was decreased in the paclitaxel group and Chinese medicine intervention groups （P<0.01）. The model group showed higher protein levels of MMP-9， TGF-β， and Snail1 and lower protein level of E-cadherin in the tumor tissue than in the normal control group （P<0.01）. Compared with model group， paclitaxel and Chinese medicine interventions downregulated the protein levels of MMP-9， TGF-β， and Snail1 （P<0.05， P<0.01） and upregulated the protein level of E-cadherin in the tumor tissue （P<0.01）. Moreover， the Liuwei Dihuang Erzhiwan combination group had lower protein levels of TGF-β and Snail1 than the Liuwei Dihuangwan group and Erzhiwan group （P<0.05）. In the metastatic lung tissue， the expression of CCL9 and CCR1 was higher in the model group than in the normal control group， paclitaxel group， and Chinese medicine intervention groups （P<0.05， P<0.01）. ConclusionLiuwei Dihuang Erzhiwan combination inhibit tumor growth， prolong survival time， and reduce the occurrence of lung metastasis in the mouse model of spontaneous breast cancer by reducing the recruitment of MDSCs in the tumor and lung tissues and modulating the phenotypes of epithelial-mesenchymal transition （EMT）-related molecules and the expression of CCL9/CCR1.

Objective To compare the anesthetic effect and safety of Ciprofol and Propofol combined with Fentanyl in painless bronchoscopy for conscious patients in intensive care unit(ICU).Methods 60 conscious patients who underwent painless bronchoscopy from October 2022 to January 2023 were selected.According to the random number table method,30 cases were divided into the control group(Propofol 1.5 mg/kg + Fentanyl 1 μg/kg)and 30 cases were divided into the experimental group(Ciprofol 0.4 mg/kg + Fentanyl 1 μg/kg).Systolic blood pressure,diastolic blood pressure,heart rate,respiratory frequency,and percutaneous arterial oxygen saturation(SpO2)were recorded before anesthesia(T1),during the examination(T2),and at the completion of the examination(T3)in the two groups,and the success rate of induction of general anesthesia,the time of induction of anesthesia,the time of bronchoscopy,the time of eye-opening,the total dosage of medications used,the incidence of injection pain,and the incidence of intraoperative adverse reactions(hypotension,respiratory depression,bradycardia,and bucking)in the two groups were compared.Results Analysis of the data revealed significant group,time,and interaction effects for systolic blood pressure,diastolic blood pressure,heart rate,and respiratory frequency at different time points(P<0.05).The experimental group had a shorter induction time of anesthesia[1.40(1.10,1.62)min]in comparison to the control group[1.60(1.30,2.10)min](P<0.05),and the experimental group required a less amount of drug to achieve the desired outcome[(21.40±1.82)mg]compared to the control group[(78.75±6.71)mg](P<0.05).Furthermore,the incidence of injection pain(3.33%)and respiratory depression(6.67%)was significantly reduced in the experimental group compared to the control group(36.67%)and(30.00%)(P<0.05).Conclusion The use of Ciprofol in combination with Fentanyl has been found to provide effective anesthesia during bronchoscopy,while also increasing safety and decreasing the incidence of adverse events.It is worthy of clinical application.

OBJECTIVE To study the effects of Phellodendron amurense polysaccharides （PAP） on improving gouty nephropathy （GN） in rats， and to investigate its mechanism primarily by interfering the p38 mitogen-activated protein kinase （p38 MAPK）/nuclear factor-κB（NF-κB）/tumor necrosis factor-α（TNF-α）. METHODS Sixty rats were randomly divided into normal group （water）， model group （water）， allopurinol group （positive control， 20 mg/kg）， PAP high-dose， medium-dose and low-dose groups （100， 50， 25 mg/kg， by raw material） after being stratified by body weight， with 10 rats in each group. Except for the normal group， the other groups were induced to construct GN model by giving 1 500 mg/kg potassium oxazinate and 100 mg/kg adenine intragastrically for 14 days. After modeling， the rats in each group were given relevant medicine/water intragastrically， once a day， for consecutive 28 days. After the last medication， the levels of biochemical parameters related to renal function [uric acid， creatinine （Cr）， blood urea nitrogen （BUN）， xanthine oxidase （XOD）] were detected in rats， and the histopathological changes in the rat kidney were observed. The protein expressions of monocyte chemoattractant protein-1（MCP-1），TNF-α and interleukin-6（IL-6） as well as the phosphorylation levels of p38 MAPK and NF-κB p65 protein were determined in renal tissue of rats. RESULTS Compared with the normal group， the model group suffered from the dilatation of renal tubules， structural damage to glomeruli， accompanied by inflammatory infiltration and fibrosis； the contents of uric acid， Cr， BUN and XOD， the protein expressions of MCP-1，TNF-α and IL-6 and the phosphorylation levels of p38 MAPK and NF-κB p65 protein were all increased significantly （P＜0.05 or P＜0.01）. Compared with the model group， the pathological symptoms of renal tissue in rats had been improved to varying degrees in different dose groups of PAP； the contents of uric acid， Cr， BUN and XOD， protein expressions of MCP-1， TNF-α and IL-6， the phosphorylation levels of p38 MAPK and NF-κB p65 protein in PAP high-dose and PAP medium-dose groups were all decreased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS PAP exhibits an anti-GN effect， the mechanism of which may be associated with inhibiting the p38 MAPK/NF-κB/TNF-α signaling pathway.

Objective:Osteosarcoma is the most common malignant bone tumor in children and adolescents,characterized by a high potential for proliferation and metastasis.Patients with osteosarcoma who have distant metastases generally have a poor prognosis.Challenges in treatment include incomplete resection of tumor and chemotherapy resistance,with no effective cure currently available.Recent studies suggest that β-1,4-N-acetyl-galactosaminyltransferase 1(B4GALNT1)plays a role in the progression of various malignant tumors.However,the function of B4GALNT1 in osteosarcoma cells has not been reported.This study aims to investigate the expression of B4GALNT1 in osteosarcoma tissues compared to normal tissues and to explore its effects on the proliferation,migration,and invasion of osteosarcoma cells,thereby providing new theoretical foundations and directions for the treatment of osteosarcoma patients. Methods:Tumor tissues and corresponding normal tissue samples were collected from 16 osteosarcoma patients who underwent tumor resection at the Second Xiangya Hospital of Central South University.The patients'ages ranged from 8 to 17 years(median age 12 years).The expression of B4GALNT1 mRNA in osteosarcoma tissues,corresponding normal tissues,3 osteosarcoma cell lines(MG63,Saos-2,and U2OS),and human fetal osteoblastic cells(hFOB)was detected using real-time reverse transcription PCR(real-time RT-PCR).The effects of B4GALNT1 knockdown on the proliferation of osteosarcoma cells Saos-2 and U2OS were analyzed using cell counting kit-8(CCK-8)assays and colony formation assays.The effects of B4GALNT1 knockdown on the migration and invasion abilities of Saos-2 and U2OS cells were evaluated using Transwell migration and invasion assays.Western blotting analysis was performed to assess the impact of B4GALNT1 knockdown on the expression of epithelial-mesenchymal transition(EMT)and invasion-related proteins in Saos-2 and U2OS cells. Results:Real-time RT-PCR results showed that B4GALNT1 mRNA expression levels were significantly higher in osteosarcoma tissues and the 3 osteosarcoma cell lines compared to normal tissues and hFOB cells(all P＜0.0 1).CCK-8 and colony formation assays indicated that B4GALNT1 knockdown significantly reduced the proliferation rate of osteosarcoma cells compared to the control group(all P＜0.05).Transwell migration and invasion assays demonstrated that B4GALNT1 knockdown significantly decreased the number of migrating and invading osteosarcoma cells(all P＜0.01).Western blotting analysis revealed that B4GALNT1 knockdown inhibited the expression of N-cadherin,Snail,Vimentin,and matrix metalloproteinase 9(MMP9)compared to the control group(all P＜0.01). Conclusion:B4GALNT1 is upregulated in osteosarcoma tissues and cell lines,and its knockdown suppresses the malignant phenotype of osteosarcoma cells.B4GALNT1 may function as an oncogene in the proliferation and metastasis of osteosarcoma cells.

OBJECTIVE To investigate the effect of Lycii Fructus-Chrysanthemi Flos herbal pair on the occurrence and progres-sion of light source-induced myopia in guinea pigs.METHODS The three-band fluorescent lamp was used to irradiate guinea pigs to establish a model of light source-induced myopia.Lycii Fructus-Chrysanthemi Flos herbal pair extract was added in the feed to raise guinea pigs.Ophthalmic A-type ultrasonic measuring instrument was used to detect the eye axis.HE staining was used to observe pathological damage to the retina of the guinea pigs.Enzyme-linked immunosorbent assay(ELISA)was used to detect dopamine(DA)and melatonin(MT)levels in guinea pig retinas,and transcriptomic analysis and other methods were used to explore the effects of Lycii Fructus-Chrysanthemi Flos on light-induced myopia in guinea pigs.RESULTS After 6 weeks,compared with the normal group,the eye axis of model group guinea pigs increased significantly(P<0.01),thus,the myopia model was successfully established.Lycii Fruc-tus-Chrysanthemi Flos herbal pair extract could effectively slow down the thickening of the lens and the deepening of the vitreous cavi-ty,thereby delaying the overgrowth of the eye axis in model guinea pigs.The retinal tissue of guinea pigs in the model group became thinner,the thickness and number of cells in the inner and outer nuclear layer of the retina were significantly reduced,the ganglion nu-clei were sparse,the vacuolization of the ganglion cell layer was obvious.Lycii Fructus-Chrysanthemi Flos extract could protect retinal cells.The thickness and cell number of the retinal inner nuclear layer and outer nuclear layer were increased,and ganglion cell nuclei were increased.ELISA assay showed that the concentrations of DA and MT in the retina of model group guinea pigs were significantly reduced(P<0.05),and the medium and high doses of Lycii Fructus-Chrysanthemi Flos herbal pair extract could effectively increase the concentration of dopamine in the retina and serum of guinea pigs in the model group(P<0.01,P<0.001).The differential genes screened by eye transcriptomics analysis were mainly enriched in PPAR signals pathway,collagen-containing extracellular matrix and other related pathways.ELISA results showed that the high dose of Lycii Fructus-Chrysanthemi Flos extract could significantly increase the content of PPARγ and COL1A1(P<0.01)and reduce the content of SMA(P<0.05).CONCLUSION The Lycii Fructus-Chry-santhemi Flos herbal pair extract has effects on delaying the occurrence and progression of light source-induced myopia in guinea pigs,protecting retinal cells,improving DA secretion disorders caused by artificial light environment,and regulating the level of PPAR,which has positive significance for the prevention and control of light source-induced myopia and provides a scientific basis for the ra-tional use of drugs in clinical practice and the creation of eye health products.

Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.
