Objective:To explore the impact of the Yiqi Huoxue formula combined with nucleos(t)ide analogs (NAs) antiviral therapy on the serum N-glycan abundance in patients with hepatitis B-related liver fibrosis so as to clarify the application value of the oligosaccharide chain test (GT) for dynamic monitoring of the liver fibrosis progression.Methods:Sixty-two cases diagnosed with chronic hepatitis B at the Department of Hepatology, the Third Hospital of Hebei Medical University, between January 2020 and December 2022 were enrolled and divided into a Yiqi Huoxue Formula (YQHX) combined with NAs group and an NAs monotherapy group ( n=31), with 31 cases in each group for a total of 96 weeks of follow-up. Patient's basic clinical characteristics and liver stiffness measurement (LSM) were collected. GT was used simultaneously to detect the serum N-glycan profile and abundance changes. The nonparametric Mann-Whitney U test was used to compare the differences between the two groups. Enumeration data were expressed as number of cases and percentages (%). The χ2 test was used to compare constituent ratios between two or more groups. Correlation analysis was performed using the Spearman method, with P<0.05 considered statistically significant. Results:The proportion of patients was significantly higher in the YQHX combined with NAs group than the NAs monotherapy group [61.29% (19/31) vs. 9.68% (3/31), P<0.05] with no progression in liver fibrosis staging following 96 weeks of follow-up. The abundance of the N-glycan marker peak 8 [triantennary N-glycan (NA3)] had resulted in significant change for liver fibrosis improvements ( P<0.05), which predicts liver fibrosis progression and reversal in populations sensitive to traditional Chinese medicine. Conclusion:The combined application of Yiqi Huoxue formula and NAs can significantly promote the improvement rate of hepatitis B-related liver fibrosis. Serum N-glycan peak 8 may serve as a potential biomarker for monitoring the reversal of hepatitis B-related liver fibrosis.

OBJECTIVE To prepare polyethylene glycol （PEG）-modified flower lactose （FL） loaded Curcumin （Cur） solid lipid nanoparticle （SLN） inhalable micropowder （referred to as “PEG-Cur-FL”）. METHODS PEG-Cur-FL was prepared by the solvent emulsification diffusion low-temperature solidification method， and its encapsulation efficiency， drug loading capacity， powder properties， aerodynamic particle size， in vitro deposition properties， and in vitro release characteristics were characterized. The mice were divided into Cur-SLN-FL （unmodified with PEG） group and PEG-Cur-FL group， with 55 mice in each group. Both groups of mice were given a single inhalation of 5 mg/kg （calculated as Cur） of the corresponding drug micropowder through an air tube. At 0.25， 0.5， 1， 2， 4， 6， 8， 12， 24， 48 and 72 hours after administration， eyeballs were removed to collect blood and tracheal， lung， liver and kidney tissues were separated. The mass concentration of Cur in mouse plasma and various tissue samples was measured， and the tissue distribution and retention of the drug were analyzed. RESULTS The encapsulation efficiency and drug loading capacity of PEG-Cur-FL were （86.2±1.8）% and （4.2±0.2）%， respectively； the bulk density and tap density were （0.24±0.01） g/cm3 and （0.30±0.01） g/cm3， respectively； the aerodynamic particle size was （2.74±0.64） μm； the in vitro effective site deposition rate （secondary drug deposition rate） was （45.07±2.79）%. Compared with Cur raw materials， Cur-SLN- FL and PEG-Cur-FL had sustained release effects under both leakage and non-leakage conditions， and PEG-Cur-FL had a smoother sustained release in artificial lung fluid， with release characteristics consistent with the Weibull model. The results of in vivo distribution showed that the drug concentration in the lung tissue of PEG-Cur-FL group was significantly lower than that of Cur- SLN-FL group during the same period after 1 hour of administration， while the drug concentration in the lung tissue at 4 to 48 hours was significantly higher than that of Cur-SLN-FL group during the same period （P＜0.05）； the plasma drug concentrations of the PEG-Cur-FL group at all time points from 0.25 to 12 hours were significantly lower than those of the Cur-SLN-FL group during the same period （P＜0.05）， and the drug concentrations in liver and kidney tissues were also lower than those of the Cur-SLN-FL group during the same period （P＜0.05）. CONCLUSIONS PEG-Cur-FL is prepared successfully； the inhalable micropowder has good inhalability and release performance； after administration through the trachea， the effective concentration of Cur in lung tissue can be increased， while reducing its plasma drug concentration and drug distribution concentration in non-target organs.

Objective:To explore the effect of the combination of robot-assisted total knee arthroplasty and pressure sensor on early postoperative outcomes.Methods:Twenty patients who underwent YUANHUA robot-assisted TKA between September 2024 and December 2024 were prospectively enrolled. After randomization and exclusion of one patient lost to follow-up, 10 patients were included in the pressure-sensor group and 10 in the control (no-pressure) group. In the pressure-sensor group, surgeons used a pressure sensor to assist in soft tissue balancing after osteotomy, whereas in the control group, balancing was performed empirically. In both groups, medial and lateral compartment pressures of the knee at 10°, 45°, 90°, and 120° of flexion were recorded using a pressure sensor prior to component implantation. Clinical outcomes were evaluated preoperatively and at 1 day, 3 days, 1 week, 2 weeks, 6 weeks, and 3 months postoperatively using the visual analog scale (VAS), Knee Society Score (KSS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Forgotten Joint Score (FJS).Results:All 20 procedures were completed successfully, and patients were followed for at least 3 months. At 10° of knee flexion, the difference between medial and lateral compartment pressures was significantly smaller in the pressure-sensor group (0.99±59.44 N) than in the control group (97.18±84.34 N; t=-2.948, P=0.009). At 45° of flexion, the corresponding differences were -12.99±36.20 N and 51.48±76.40 N, respectively ( t=-2.411, P=0.032). No significant differences in VAS, KSS, or WOMAC scores were observed between groups preoperatively ( P>0.05). At 3 months postoperatively, the KSS was significantly higher in the pressure-sensor group (174.40±16.39) compared with the control group (138.50±38.35, t=2.722, P=0.014). The WOMAC and VAS scores were significantly lower in the pressure-sensor group (12.70±11.00 and 1.20±0.92, respectively) than in the control group (27.30±18.54 and 2.70±2.00; t=-2.142, P=0.046; t=-2.153, P=0.045). At 2 weeks and 3 months postoperatively, the FJS scores in the pressure-sensor group [70.00±26.06 and 88.07(83.52, 95.83)] were significantly higher than those in the control group [37.92±32.42 and 50.00(32.50, 67.75); t=2.439, P=0.025; Z=-2.466, P=0.014]. Conclusion:The combination of precise osteotomy using robot-assisted TKA and soft tissue balancing guided by a pressure sensor provided more accurate medial-lateral compartment balance and significantly enhanced early postoperative clinical outcomes.

Objective To construct fluorescent molecular probes targeting at tumor heat shock protein 90(Hsp90)in order to enhance tumor-specific recognition.Methods The human pancreatic adenocarcinoma cell line PANC-1 and the human small cell lung cancer cell line NCI-H446 were used as the research targets to study the uptake and clearance of Cy5-P7 by tumor cells with flow cytometry as well as immune-fluorescence technology;The mechanism to mediate entrance of Cy5-P7 into the cells by Hsp90 was investigated by blocking of the PANC-1 cell surface pro-teins with monoclonal antibody to Hsp90;Human pancreatic cancer cell line PANC-1 was subcutaneously injected into posterior dorsum of BALB/c nude mice to construct a xenogeneic subcutaneous tumor model to validate the in vivo tumor recognition ability by Cy7-P7 as well as its in vivo distribution in mice.Results The uptake of Cy5-P7 by cells was significantly reduced in low temperature(P<0.05);An average fluorescence intensity in Cy5-P7-trea-ted cells was significantly reduced after blocking with a monoclonal antibody to Hsp90(P<0.05);The fluorescence intensity at the tumor site of Cy7-P7 group was higher than that of control group(P<0.05),and there was a significant presence of Cy7-P7 in the kidney and tumor fluorescence.Conclusions Cy5-P7 can effectively target at Hsp90,and its specific binding significantly enhanced the cellular uptake of Cy5-P7 fluorescent probe,which im-proved the sensitivity and accuracy of fluorescence imaging.Cy7-P7 showed good tumor active recognition in vivo,and was able to be enriched at the tumor site and metabolized out of the body in 48 h,which may effectively sup-port accurate tumor recognition.

Objective To explore the effects of modified prone ventilation combined with bronchoscopic alveolar lavage on respiratory mechanics and hemodynamics in children with Acute Respiratory Distress Syndrome(ARDS),as well as to evaluate the clinical treatment efficacy.Methods A total of 96 ARDS children receiving mechanical ventilation treatment in the emergency intensive care unit of Kunming Children's Hospital from January 2021 to December 2023 were selected and randomly assigned into three groups:Group A(prone ventilation group,n=32),Group B(modified prone ventilation group,n=32),and Group C(modified prone ventilation combined with bronchoscopic alveolar lavage group,n=32).The changes in the following parameters before and after treatment among the three groups were compared:oxygenation indicators:arterial oxygen partial pressure(PaO2),arterial oxygenation index(PaO2/FiO2);respiratory mechanics indicators:lung compliance,mean airway pressure,plateau airway pressure,and total airway resistance;hemodynamic indicators:cardiac output,cardiac index,systemic vascular resistance index,and mean arterial pressure;clinical efficacy indicators time to disappearance of rales,mechanical ventilation duration,and length of hospital stay;and incidence of complications:arrhythmia,airway obstruction,pressure injuries,total incidence of catheter dislodgment,and gastric content reflux.Results The oxygenation indicators in Group C after treatment were superior to those in Groups A and B(P<0.05).The respiratory mechanics indicators in Group C after treatment were also better than those in Groups A and B(P<0.05).In terms of hemodynamics,there were no statistically significant differences in cardiac output,cardiac index,and mean arterial pressure among Groups A,B,and C after treatment(P>0.05).However,the SVRI in Group C was better than that in Groups A and B(P<0.05).Curative effect for Group C were also better than those for Groups A and B(P<0.05).The incidence of complications in Group C showed no significant difference compared to Groups A and B(P>0.05).Conclusion The modified prone ventilation combined with bronchoscopic alveolar lavage treatment scheme demonstrates better therapeutic effects compared to traditional treatment methods,significantly improving oxygenation and respiratory mechanics indicators as well as the systemic vascular resistance index in children,and is worthy of clinical promotion.

Social working memory (SWM)-the ability to maintain and manipulate social information in the brain-plays a crucial role in social interactions. However, research on SWM is still in its infancy and is often treated as a unitary construct. In the present study, we propose that SWM can be conceptualized as having two relatively independent components: "externally oriented SWM" (e-SWM) and "internally oriented SWM" (i-SWM). To test this external-internal hypothesis, participants were tasked with memorizing and ranking either facial expressions (e-SWM) or personality traits (i-SWM) associated with images of faces. We then examined the neural correlates of these two SWM components and their functional roles in empathy. The results showed distinct activations as the e-SWM task activated the postcentral and precentral gyri while the i-SWM task activated the precuneus/posterior cingulate cortex and superior frontal gyrus. Distinct multivariate activation patterns were also found within the dorsal medial prefrontal cortex in the two tasks. Moreover, partial least squares analyses combining brain activation and individual differences in empathy showed that e-SWM and i-SWM brain activities were mainly correlated with affective empathy and cognitive empathy, respectively. These findings implicate distinct brain processes as well as functional roles of the two types of SWM, providing support for the internal-external hypothesis of SWM.

Eight new diterpenoids, Isodons A-H (1-8), comprising seco-abietane and abietane-type structures, together with 13 known analogues (9-21), were isolated from Isodon lophanthoides (Buch.-Ham. ex D. Don) Hara. The compounds (+)-3/(-)-3, (+)-4/(-)-4, and (+)-5/(-)-5 were identified as three enantiomeric pairs. The planar structures and absolute configurations of 1-8 were determined through high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), 1D & 2D nuclear magnetic resonance (NMR) spectroscopy, electronic circular dichroism (ECD) calculations, and X-ray diffraction crystallography. A cholesterol 7α-hydroxylase (Cyp7a1) luciferase reporter assay revealed significant anti-cholestatic activities for compounds 1, (+)-4, 6, 7, 12-14, and 16. Additionally, compound 6 demonstrated anti-cholestatic effects through the farnesoid X receptor (FXR)-associated signaling pathways in vitro and in vivo. These findings suggest potential applications for I. Lophanthoides in pharmaceutical development.

Hepatic fibrosis is a key pathological process in the development of chronic liver disease to cirrhosis, and its core mechanism involves the activation of hepatic stellate cells(HSC) and abnormal deposition of extracellular matrix(ECM). Although existing treatments, such as antiviral drugs, can delay disease progression, they have the problem of single therapeutic targets and cannot reverse fibrosis. Accordingly, multidimensional intervention strategies are urgently needed. Recent studies have shown that circadian rhythm disorders aggravate hepatic fibrosis by regulating metabolism, immunity, and inflammation. Traditional Chinese medicine(TCM) plays a unique role in restoring the circadian clock via multi-target and holistic regulation. This paper establishes a three-dimensional network by systematically integrating biological clock, metabolism, and immunity for the first time to elucidate the scientific connotation of the theory of time-concerned treatment of TCM, and proposes a new strategy for the development of time-targeted compound prescriptions, providing innovative ideas for the treatment of hepatic fibrosis.

OBJECTIVES: To investigate the effects of methylenetetrahydrofolate reductase (MTHFR) rs1801133 and γ-glutamyl hydrolase (GGH) rs11545078 gene polymorphisms on plasma concentrations and toxicity following high-dose methotrexate (MTX) therapy in children with acute lymphoblastic leukemia (ALL). METHODS: Children with ALL treated at the Xuzhou Children's Hospital of Xuzhou Medical University from January 2021 to April 2024 were selected for this study. Genotypes of MTHFR rs1801133 and GGH rs11545078 were determined using multiplex polymerase chain reaction. MTX plasma concentrations were measured by enzyme-multiplied immunoassay technique, and toxicity was graded according to the Common Terminology Criteria for Adverse Events version 5.0. The relationships between MTHFR rs1801133 and GGH rs11545078 genotypes and both MTX plasma concentrations and associated toxicities were analyzed. RESULTS: In the low-risk ALL group, the MTHFR rs1801133 genotype was associated with increased MTX plasma concentrations at 72 hours (P<0.05). In the intermediate- to high-risk group, the MTHFR rs1801133 genotype was associated with increased MTX plasma concentrations at 48 hours (P<0.05), and the GGH rs11545078 genotype was associated with increased MTX plasma concentrations at 48 hours (P<0.05). In the intermediate- to high-risk group, the MTHFR rs1801133 genotype was associated with the occurrence of reduced hemoglobin (P<0.05), and the GGH rs11545078 genotype was associated with the occurrence of thrombocytopenia (P<0.05). CONCLUSIONS Detection of MTHFR rs1801133 and GGH rs11545078 genotypes can be used to predict increased MTX plasma concentrations and the occurrence of toxic reactions in high-dose MTX treatment of ALL, enabling timely interventions to enhance safety.
