Objective To evaluate the therapeutic effects of different intracranial pressure lower-ing regimens in patients with acute large-area cerebral infarction based on electrical impedance tomo-graphy(EIT)technology.Methods A total of 75 patients with acute large-area cerebral infarction were selected as the study subjects and randomly divided into study group(n=40,using mannitol combined with albumin to decrease intracranial pressure)and control group(n=35,using mannitol alone to decrease intracranial pressure).EIT technology was used to continuously monitor the changes in intracranial pressure within 48 hours in the patients.Clinical data of the two groups were collected,and the 24-hour intracranial pressure change rate,48-hour intracranial pressure change rate,ICU stay duration,hospitalization duration,antibiotic use duration,and National Institutes of Health Stroke Scale(NIHSS)score at discharge were observed and compared between the two groups.A 90-day sur-vival follow-up was also conducted.Results There was no statistically significant difference in the 24-hour intracranial pressure change rate between the two groups(P＞0.05).The 48-hour intracrani-al pressure change rate in the study group was higher than that in the control group,and the difference was statistically significant(P＜0.05).The ICU stay duration,hospitalization duration,and antibiotic use duration in the study group were all shorter than those in the control group,and the NIHSS score at discharge in the study group was lower than that in the control group,with statistically significant differences(P＜0.05).The follow-up results showed that the survival duration in the study group was longer than that in the control group,and the 90-day cumulative survival rate in the study group was higher than that in the control group,but the differences were not statistically significant(P＞0.05).The modified Rankin Scale score in the study group was lower than that in the control group,and the difference was statistically significant(P＜0.05).Conclusion Compared with the use of mannitol alone,early use of mannitol combined with albumin can effectively decrease the in-tracranial pressure within 48 hours,shorten the hospitalization duration,and improve neurological function in patients with acute large-area cerebral infarction.

Objective:To explore the therapeutic effect of compound Kuijie Ankang Decoction on ulcerative colitis (UC) model mice by non targeted metabonomics; To explore its mechanism.Compound Kuijie Ankang.Methods:The mice were randomly divided into blank control group, model group, Kuijie Ankang Decoction group and sulfasalazine group, with 12 mice in each group. Except the blank control group, the other groups were given 1.5% DSS solution for free drinking to prepare UC model. After successful modeling, Kuijie Ankang Decoction group was intragastrically administered with compound Kuijie Ankang Decoction of 9.68 g/kg, sulfasalazine group was intragastrically administered with sulfasalazine capsule suspension of 320 mg/kg, model group and blank control group were intragastrically administered with equal volume of purified water, once a day, for 7 consecutive days. The body mass and disease activity index (DAI) score of mice were measured. ELISA was used to measure the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6), and interleukin-10 (IL-10) in the colon tissue of mice; the protein expressions of Claudin-1 and Zo-1 in colon tissue were detected by immunofluorescence method. HE staining was used to observe the pathological changes in the colon, and UHPLC-OE-MS technology was used to analyze the endogenous metabolite structure of mouse colon tissue, differential metabolites and related metabolic pathways were screened.Results:Compared with the model group, the colon length in Kuijie Ankang Decoction group and sulfasalazine group increased ( P<0.01), the DAI score decreased ( P<0.01), the levels of TNF-α, IL-1β and IL-6 in colon tissue decreased ( P<0.01), the level of IL-10 increased ( P<0.01), and the average optical density of Claudin-1 and Zo-1 protein increased ( P<0.01 or P<0.05). Metabolomics analysis identified 26 potential differential metabolites, including nicotinamide adenine dinucleotide, guanine, gamma aminobutyric acid, and thiamine, affecting 26 key metabolic pathways, including lysine biosynthesis, thiamine metabolism, cysteine and methionine metabolism. Conclusion:Kuaijie Ankang Decoction may improve metabolites such as Gamma aminobutyric acid and thiamine through metabolic pathways such as lysine biosynthesis to alleviate inflammatory reactions, thereby exerting therapeutic effects on ulcerative colitis in mice.

ObjectiveTo investigate the immunomodulatory effect of polysaccharides from Astragali Radix-Angelicae Sinensis Radix herb pair（Qi-gui polysaccharides） on lipopolysaccharide（LPS）-induced RAW264.7 macrophages and to characterize the structure of the active component Qi-gui homogeneous polysaccharide（AAPS-4a）， and evaluate its protective effect on ulcerative colitis（UC）. MethodsThe effects of six Qi-gui polysaccharides（0.01-100 mg·L^-1） on the proliferation of RAW264.7 cells were assessed by cell proliferation and activity assay（CCK-8）， and enzyme-linked immunosorbent assay（ELISA） was used to investigate the effects of the six polysaccharides（3， 10 mg·L^-1） on the secretion levels of tumor necrosis factor（TNF）-α， interferon（IFN）-β， and nitric oxide（NO） in LPS-induced RAW264.7 cells. After screening for active polysaccharides， high-performance size-exclusion chromatography（HPSEC） was used to determine its homogeneity and relative molecular weight， then its characteristic functional groups were identified by Fourier transform infrared spectroscopy（FT-IR）， monosaccharide composition was analyzed by high performance liquid chromatography（HPLC）， methylation analysis combined with gas chromatography-mass spectrometry（GC-MS） was performed to determine the types and linkage modes of sugar residues， and one- and two-dimensional nuclear magnetic resonance（NMR） were used to identify the sugar residue composition and configuration of the active polysaccharide. Finally， experimental animals were divided into the normal group， model group， AAPS-4a low-dose group（50 mg·kg^-1）， AAPS-4a high-dose group（100 mg·kg^-1）， and sulfasalazine（SASP） group （75 mg·kg^-1）. Except for the normal group， the acute UC mouse model was induced using 3.5% dextran sulfate sodium salt（DSS）. Each treatment group was administered the corresponding dose via oral gavage for 7 days， and changes in body weight were recorded. After treatment， the spleen index and disease activity index（DAI） score were calculated， TNF-α and interleukin-6（IL-6） levels in the serum were detected by ELISA， and histopathological changes in colon tissue were observed by hematoxylin-eosin（HE） staining. ResultsAt the cellular level， AAPS-4a exhibited a dose-dependent inhibition of LPS-induced increases in TNF-α， IFN-β， and NO levels（P<0.01）. Structural characterization of AAPS-4a revealed that it was a homogeneous polysaccharide with a relative molecular weight of 7.6×10³ Da， consisting of mannose（Man）， glucose（Glc）， and galactose（Gal） in a molar ratio of 1.3∶23.9∶1.0. It was primarily composed of five sugar residues of 1，6-α-D-Glcp， T-α-D-Glcp， 1，3-β-D-Galp， 1，4-α-D-Manp， and 1，2-α-D-Galp. In vivo experiments showed that compared with the normal group， the model group demonstrated markedly increased DAI score and spleen index， significantly reduced colon length， and significantly elevated levels of TNF-α and IL-6（P<0.01）. Compared with the model group， the AAPS-4a high-dose group significantly reduced the DAI score and spleen index， as well as TNF-α and IL-6 levels， and improved colonic atrophy（P<0.05， P<0.01）. Pathological observations showed that AAPS-4a significantly inhibited inflammatory cell infiltration in colon tissue and alleviated pathological damage. ConclusionAAPS-4a， a neutral homogeneous polysaccharide composed of 1，6-α-D-Glcp， T-α-D-Glcp， 1，3-β-D-Galp， 1，4-α-D-Manp and 1，2-α-D-Galp， is identified as a key bioactive component contributing to the anti-UC effect of the Qi-gui herb pair. Its immunoregulatory and anti-UC properties suggest its potential as a therapeutic agent for UC.

The integration of medical treatment and disease prevention(hereinafter referred to as"med-prevent integra-tion")constitutes a vital strategy for achieving universal health objectives.Party-building initiatives in university-affiliated hospi-tals present a novel approach to enhance this integration at the primary care level.This study identifies three major challenges in current practice,including insufficient conceptual integration between medical and preventive services,inadequate cross-depart-mental coordination and resource allocation,and imperfect accountability mechanisms within Party-building frameworks.From the perspective of integrated governance,we propose a comprehensive pathway where party-building facilitates the systematic conver-gence of ideological orientation,organizational structure,cultural values,and institutional mechanisms.These findings provide both theoretical framework and practical guidance for university-affiliated hospitals to deepen primary-level med-prevent integration through Party-building initiatives.

Ulcerative colitis(UC)is a common disease of the digestive system.Phosphatidylinositol-3-kinase(PI3K)/synuclein/threonine kinase(AKT)is closely related to cell survival,apoptosis,inflammation and other biological processes,and the expression levels of PI3K and AKT significantly increase during the course of UC,with accelerated apoptosis,improved inflammation,and damaged intestinal mucosal barrier function.In recent years,a large number of basic and clinical trials have been conducted on PI3K/AKT signaling pathway in TCM,and the results indicate that PI3K/AKT signaling pathway is expected to be an important potential target for UC treatment.This article analyzed the mechanism of the regulation of PI3K/AKT signaling pathway in TCM from monomer,extract,compound and acupuncture,and suggested that the regulation of this signaling pathway is of great significance for the prevention and treatment of UC,and provide reference for drug development.

Objective:To systematically investigate the short-term efficacy of total knee arthroplasty in the treatment of osteoarthritis coupled with fixed patellar dislocation.Methods:A retrospective analysis was conducted on a cohort of 11 patients diagnosed with knee osteoarthritis and fixed patellar dislocation who underwent total knee arthroplasty at Panzhihua Central Hospital from January 2018 to October 2021. The cohort comprised 4 males and 7 females, aged 63.45±4.76 years (range, 56-70 years), all of whom underwent unilateral surgery. There were 5 left and 6 right knees, with a body mass index of 23.20±2.02 kg/m 2 (range, 20.8-27.6 kg/m 2) and a disease course of 12.63±4.81 years. According to the American Society of Anesthesiologists classification, 9 cases were categorized as grade II, and 2 cases as grade III. Recovery of patellar trajectory during total knee arthroplasty, using medial synovial flap transposition to repair lateral joint capsule. Preoperative and postoperative assessments included knee joint range of motion, Knee Society score (KSS), University of California Los Angeles (UCLA) score, and visual analogue scale (VAS). Results:All 11 patients were followed up for a period of 28.64±4.01 months (range, 24-36 months). Two patients exhibited subcutaneous fat liquefaction locally after surgery, which resolved following dressing changes. All wounds achieved primary healing. Two of them developed intramuscular vein thrombosis after surgery and were cured after anticoagulant treatment. The range of motion of the knee joint increased from 63.18°±17.07° before surgery to 104.55°±16.80° at the last follow-up, with a statistically significant difference ( t=14.041, P<0.001). The KSS score increased from 38.00±6.78 points to 80.91±5.65 points, with a statistically significant difference ( t=16.472, P<0.001). The UCLA score increased from 3.18±1.17 to 6.73±1.35, with a statistically significant difference ( t=9.694, P<0.001). The VAS decreased from 6.09±0.94 points to 2.32±0.64 points, with a statistically significant difference ( t=16.600, P<0.001). At the last follow-up, imaging examinations showed no cases of patellar subluxation or dislocation, no tearing or breakage of the knee extension device, and no infection or loosening around the prosthesis. Conclusion:Utilizing medial synovial flap transposition for repairing the lateral joint capsule proves to be an effective technique for key capsule repair. Total knee arthroplasty for osteoarthritis combined with fixed patellar dislocation demonstrates satisfactory early clinical outcomes.
