Hepatic alveolar echinococcosis is a highly invasive zoonotic parasitic disease with poor prognosis. Surgical intervention serves as the pivotal approach to achieve radical cure and improve the prognosis of hepatic alveolar echinococcosis patients. In recent years, with the popularization of the concept of precision surgery and the development of the multidisciplinary diagnosis and treatment model, the surgical treatment strategies for hepatic alveolar echinococcosis have been continuously enriched, and the selection of surgical procedures has become increasingly diversified. Although key surgical techniques such as radical hepatectomy, autologous liver transplantation and allogeneic liver transplantation have achieved remarkable progress in clinical application, many insurmountable challenges still remain. Therefore, by sorting out the latest evidence-based advances in the field of surgical treatment for hepatic alveolar echinococcosis, this article focuses on discussing the application status and bottlenecks of radical hepatectomy, autologous liver transplantation and allogeneic liver transplantation in hepatic alveolar echinococcosis, aiming to provide a reference for the clinical treatment of hepatic alveolar echinococcosis.
2.Analysis of related factors for the comorbidity of allergic rhinitis and obesity among primary and secondary school students in Inner Mongolia
Chinese Journal of School Health 2026;47(1):27-31
Objective:
To investigate the factors influencing the co-prevalence of allergic rhinitis and obesity among primary and secondary school students in Inner Mongolia, so as to provide a data foundation and theoretical basis for developing targeted intervention measures.
Methods:
In September and October 2024, a stratified cluster random sampling method was employed to select 139 102 students from 539 schools across 12 leagues/cities and 103 banners/counties in Inner Mongolia Autonomous Region. Participants who were diagnosed with allergic rhinitis by a doctor at least once within one year and had a body mass index ≥ 28 kg/m 2 were considered to have comorbid conditions.
Results:
The coprevalence rate of allergic rhinitis and obesity among primary and secondary school students in Inner Mongolia was 6.4% (8 931 cases). Lasso-Logistic regression revealed that nonboarding status, higher maternal education, consuming high protein foods ≥1 time daily, occasionally or never eating breakfast, engaging in moderate to vigorous physical activity for ≥60 minutes on fewer than half of holidays, and having been exposed to second hand smoke in person within the past seven days were associated with higher odds ratios for co-prevalence of allergic rhinitis and obesity( OR = 1.23 , 1.22-1.63, 1.20, 1.19, 1.38, 1.35); being female, higher grade level, residence in flag/county/district areas, non only child status, never having consumed a full glass of alcohol, non hypertensive status, and households without pets were associated with lower co-prevalence risks ( OR =0.65, 0.67-0.77, 0.81, 0.87, 0.73, 0.41, 0.68) (all P <0.05). The ROC curve indicated an area under the curve of 0.64 for the predictive model, demonstrating satisfactory discriminatory ability. The calibration curve showed consistency between predicted and actual occurrence probabilities.
Conclusions
The co-prevalence of allergic rhinitis and obesity among primary and secondary school students in Inner Mongolia is closely associated with demographic characteristics, dietary behaviours, and lifestyle habits. Future prevention and control strategies should prioritize these factors to implement targeted interventions.

ObjectiveTo investigate the mechanisms of Runmu Dihuang decoction (RMDHD) in treating perimenopausal dry eye with liver-kidney Yin deficiency syndrome based on the silent information regulator 3 (SIRT3)/hypoxia-inducible factor-1α (HIF-1α)/nuclear factor-κB (NF-κB) signaling pathway. MethodsSixty female Sprague-Dawley rats were randomly divided into six groups (n=10 per group): Sham operation group, model group, sodium hyaluronate eye drop group, and low-, medium-, and high-dose RMDHD groups (5.625, 11.25, 22.50 g·kg-1). Except for the sham operation group, all rats underwent bilateral ovariectomy and were administered 0.1% benzalkonium chloride eye drops combined with long-term chronic irritation to establish a perimenopausal dry eye model with liver-kidney Yin deficiency syndrome. Drug administration began in the 11th week after modeling and continued for 21 days. General conditions, screen-grip test scores, tear secretion volume, tear film breakup time (TFBUT), and corneal fluorescein staining were recorded. Serum levels of reactive oxygen species (ROS), follicle-stimulating hormone (FSH), estradiol (E2), and progesterone (PROG) were measured by enzyme-linked immunosorbent assay (ELISA). Pathological changes in the lacrimal glands, corneas, and uteri were observed using hematoxylin-eosin (HE) staining. Protein expression levels of SIRT3, HIF-1α, phosphorylated NF-κB p65 (p-NF-κB p65), and total NF-κB p65 in the lacrimal glands were detected by Western blot. The expression of inflammatory cytokines interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in the lacrimal glands was assessed by immunohistochemistry (IHC). ResultsAfter model establishment, no significant differences were observed among the groups except the sham operation group. Compared with the sham operation group, the other groups exhibited slowed movement, dull responses, increased irritability, reduced body weight, elevated rectal temperature, decreased screen-grip test scores, reduced tear secretion, and significantly shortened TFBUT (P<0.05). After treatment, compared with the model group, the sodium hyaluronate eye drop group and all RMDHD groups showed improved general conditions, significantly increased tear secretion (P<0.05), prolonged TFBUT (P<0.05), and elevated screen-grip test scores (P<0.05). Serum ROS and FSH levels were significantly decreased, while E2 and PROG levels were significantly increased (P<0.05). Pathological damage to the cornea, lacrimal glands, and uterus was ameliorated. In addition, protein expression levels of SIRT3 and HIF-1α in the lacrimal glands were significantly upregulated (P<0.05), whereas the expression of p-NF-κB p65, IL-1β, and TNF-α was significantly downregulated (P<0.05). ConclusionRMDHD increases tear secretion and TFBUT, improves lacrimal gland and corneal injury, and alleviates dry eye symptoms in a perimenopausal dry eye rat model with liver-kidney Yin deficiency syndrome. The underlying mechanism may be related to regulation of the SIRT3/HIF-1α/NF-κB signaling pathway, inhibition of oxidative stress and inflammatory responses, and reduction of ocular surface tissue damage.

Renal hilar tumors pose significant surgical challenges due to their proximity to major renal vessels and the collecting system. In robot-assisted partial nephrectomy, although both anterior and posterior lip tumors are considered renal hilar tumors, their operative difficulty and complication profiles differ markedly owing to distinct anatomical relationships and vascular adjacency. Anterior lip tumors, often involving tributaries of the renal vein, carry a relatively higher risk of intraoperative and postoperative bleeding. In contrast, posterior lip tumors, closer to the renal artery, are more likely to prolong warm ischemia time, thereby increasing the risk of postoperative renal impairment. Regarding urine leakage, although anterior lip tumors are theoretically closer to the collecting system and may pose a slightly elevated risk, precision reconstruction strategies—such as lip reconstruction based on sinus space anatomy—can effectively mitigate this risk. However, the specific difference in urine leakage risk between anterior and posterior lip tumors warrants further investigation. Both anterior and posterior lip tumors of the kidney can achieve low positive surgical margin rates in experienced centers. Complication risks are affected by multiple factors, including tumor anatomical complexity, warm ischemia time, and surgeon experience. Notably, R.E.N.A.L. score>8 is associated with significantly increased complication risks. Preoperative meticulous imaging evaluation, selection of an appropriate surgical approach based on tumor location, controlled warm ischemia time, and application of delicate suturing and reconstruction techniques are essential strategies to reduce complications.

Objective To investigate the clinical prognostic value of the prognostic nutritional index (PNI) in patients with renal cell carcinoma (RCC) undergoing partial nephrectomy.Methods A retrospective analysis was conducted on the clinical data of RCC patients who underwent partial nephrectomy at our hospital during 2020 and 2024.The optimal cutoff value of PNI was determined based on the maximum Youden index from the receiver operating characteristic (ROC) curve.The clinicopathological characteristics, overall survival (OS), and progression-free survival (PFS) between patients with different PNI levels were compared.Cox regression analysis was used to explore the independent prognostic factors for RCC patients. Results Based on the ROC curve, the optimal cutoff value corresponding to the maximum Youden index was calculated to be 46.675, at which point the sensitivity was 65.3% and the specificity was 62.2%.Of the 815 patients included in the study, 293 (36.0%) patients had a PNI<46.675.Cox regression analysis confirmed that preoperative PNI, tumor diameter, ISUP classification, and ECOG score were independent risk factors for postoperative OS in patients with RCC who underwent PN (P<0.05).In addition, preoperative PNI, tumor diameter, ISUP classification and ECOG score were independent risk factors for postoperative PFS (P<0.05).After covariates in the multivariable Cox regression model were adjusted, patients in the low PNI group demonstrated significantly shorter overall survival (HR=2.392, P<0.001) and significantly poorer progression-free survival (HR=2.076, P<0.001) compared to those in the high PNI group.Conclusion Preoperative PNI has significant clinical value in evaluating the prognosis of RCC patients undergoing partial nephrectomy.An elevated preoperative PNI is associated with a better prognosis.

Abnormal synaptic plasticity is an early pathological feature of Alzheimer disease (AD). Synaptic damage and dysfunction initiate neuronal degeneration and death, ultimately leading to cognitive impairment. Traditional Chinese medicine (TCM) can effectively ameliorate cognitive dysfunction through multitarget regulation of synaptic plasticity. This review summarizes the mechanisms by which TCM, including active components, single herbs, and classical formulas, modulates synaptic plasticity, offering new insights for future research and clinical applications. Relevant experimental studies published between 2020 and 2024 were retrieved from major databases, including China National Knowledge Infrastructure, the National Science and Technology Library, Wanfang Data, Elsevier, ScienceDirect, PubMed, SpringerLink, and Web of Science. Network pharmacology and bioinformatics approaches were used to predict the therapeutic effects and mechanisms of TCM on AD-related synaptic plasticity. In total, 15 TCM single herbs and 11 TCM formulas were identified as enhancing AD-related synaptic plasticity. Additionally, 15 active ingredients targeting synaptic plasticity in AD were retrieved from TCM databases over the past decade. This review provides novel perspectives and strategic directions for future AD research and therapeutic development.

ObjectiveTo investigate the mechanism of Hei Xiaoyaosan (HXS) in ameliorating cognitive impairment in the rat model of Alzheimer's disease (AD) by regulating the adenosine 5'-monophosphate-activated protein kinase (AMPK)/sterol regulatory element-binding protein 2 (SREBP2)/proprotein convertase subtilisin/kexin type 9 (PCSK9)/low-density lipoprotein receptor-related protein 1 (LRP-1) signaling pathway to clear amyloid-β (Aβ) from the peripheral circulation. MethodsNinety 8-week-old specific pathogen-free (SPF)-grade male Sprague-Dawley (SD) rats were acclimatized for 1 week. After acclimatization, 10 rats were randomly selected as the blank control group, and the remaining 80 rats were prepared for surgical modeling. Among the 80 rats for modeling, 70 were anesthetized and injected with 1 μL of amyloid-β1-42 (Aβ1-42) solution into the bilateral hippocampal CA1 region for the modeling of AD, and the remaining 10 were assigned to the sham operation group, which received an injection of 1 μL normal saline at the same anatomical site. The successfully modeled rats were randomly assigned into 6 groups (n=10 per group): a model group, a donepezil hydrochloride group, an acadesine (AICAR, an AMPK agonist) group, and high-, medium-, and low-dose HXS groups. After 42 consecutive days of administration intervention, the Morris water maze test and T-maze test were performed to evaluate the learning and memory abilities of rats. Fluoro-Jade B (FJB) staining was conducted to observe pathological changes of neurons in the rat hippocampus, and thioflavin S staining to quantify the area of Aβ deposition in the hippocampal region. Immunofluorescence double staining (IF-DS) was performed to detect the expression of LRP-1 and Aβ signals in the liver tissue. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the levels of Aβ1-42 and soluble LRP-1 (sLRP-1) in the serum. Western blot was performed to determine the protein levels of AMPK, phosphorylated AMPK (p-AMPK), SREBP2, PCSK9, and LRP-1 in the liver tissue. Real time polymerase chain reaction(Real-time PCR) was adopted to assess the mRNA levels of AMPK, SREBP2, PCSK9, and LRP-1 in the liver tissue. ResultsCompared with the blank control group, the model group showed increased total swimming distance on day 6 and path length in the target quadrant on day 7 (P<0.01), a decreased correct alternation rate in the T-maze test (P<0.01), disarrangement of hippocampal neurons, increased FJB-positive cells (P<0.01), enlarged area of Aβ deposition (P<0.01). reduced LRP-1 fluorescence signals and enhanced Aβ fluorescence signals in the liver tissue (P<0.01), elevated serum level of Aβ1-42, declined serum level of sLRP-1 (P<0.01), downregulated protein levels of p-AMPK and LRP-1 as well as mRNA levels of AMPK and LRP-1, and upregulated protein and mRNA levels of SREBP2 and PCSK9 in the liver tissue (P<0.01). Compared with the model group, the high-dose HXS group, donepezil hydrochloride group, and AICAR group exhibited reduced total swimming distance and target quadrant path length (P<0.05, P<0.01), an increased correct alternation rate in the T-maze test (P<0.05), decreased FJB-positive cells (P<0.01), reduced Aβ deposition (P<0.01) in the hippocampal tissue, enhanced LRP-1 signals and weakened Aβ signals in the liver tissue (P<0.01), a declined serum level of Aβ1-42 and an elevated serum level of sLRP-1 (P<0.01), upregulated protein levels of p-AMPK and LRP-1 as well as mRNA levels of AMPK and LRP-1, and downregulated protein and mRNA levels of SREBP2 and PCSK9 in the liver tissue (P<0.01). ConclusionHei Xiaoyaosan can regulate the AMPK/SREBP2/PCSK9/LRP-1 signaling pathway to enhance the clearance of peripheral Aβ by the liver tissue and reduce Aβ deposition in the brain, thereby improving the learning and memory abilities of AD rats.

ObjectiveTo investigate the role and mechanism of Hei Xiaoyaosan in regulating asparaginyl endopeptidase (AEP) to inhibit tau protein (tau) phosphorylation, amyloid-beta protein (Aβ) deposition, and neuroinflammation in the prevention and treatment of Alzheimer's disease (AD). MethodsNinety SPF-grade SD male rats of 8 weeks old were selected and randomly grouped as follows: 10 rats in the blank group, 10 rats in the sham group (bilateral hippocampus injected with 1 μL normal saline), and 70 rats in the modeling group (bilateral hippocampus injected with 1 μL Aβ1-42 solution for the modeling of AD). Fifty successfully modeled rats were selected and randomly assigned into the model, donepezil hydrochloride (positive control, 0.45 mg·kg-1), and high-, medium-, and low-dose (15.30, 7.65, and 3.82 g·kg-1, respectively) Hei Xiaoyaosan groups. Rats were administrated with corresponding agents by gavage once a day for 42 days. Morris water maze and Y maze tests were carried out to assess the cognitive abilities of rats. Hematoxylin-eosin (HE) staining was employed to observe morphological changes in hippocampal neurons, and immunohistochemistry (IHC) was employed to assess phosphorylation (p)-tau and Aβ expression in the hippocampal tissue of rats. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the levels of interleukin-1 beta (IL-1β), interleukin-18 (IL-18), and Aβ1-42 in the hippocampal tissue. Western blot was employed to determine the protein levels of AEP, tau, phosphorylated tau (p-tau), α-Syn (α-Syn), phosphorylated α-Syn (p-α-Syn), Toll-like receptor 2 (TLR2), and NOD-like receptor thermal protein domain associated protein 3 (NLRP3). Real time polymerase chain reaction (Real-time PCR) was employed to determine the mRNA levels of AEP, tau, α-Syn, TLR2, and NLRP3. ResultsCompared with the blank group, the model group showed prolonged escape latency, a decreased percentage of time spent in the platform quadrant, and a decreased alternation rate (P<0.01), a reduced number, shrinkage, and increased vacuoles of hippocampal neurons, increased expression of p-tau and Aβ in the hippocampus (P<0.01), elevated levels of IL-1β, IL-18, and Aβ1-42, up-regulated protein and mRNA levels of AEP, tau, α-Syn, TLR2, and NLRP3, and up-regulated protein levels of p-tau and p-α-Syn (P<0.01). Compared with the model group, the positive control group and the high-dose Hei Xiaoyaosan group exhibited shortened escape latency (P<0.01), an increased percentage of retention time in the target quadrant, an increased alternation response rate (P<0.05, P<0.01), alleviated neuronal shrinkage, regular morphology and arrangement of neurons in the hippocampal tissue, lowered levels of p-tau and Aβ in the hippocampal tissue (P<0.05, P<0.01), declined levels of IL-1β, IL-18, and Aβ1-42, downregulated mRNA and protein levels of AEP, tau, α-Syn, TLR2, and NLRP3, and downregulated protein levels of p-tau and p-α-Syn (P<0.05, P<0.01). ConclusionHei Xiaoyaosan can protect hippocampal neurons and ameliorate cognitive impairment in the rat model of AD. Specifically, it may inhibit AEP to regulate tau phosphorylation, Aβ deposition, and neuroinflammation.

ObjectiveTo investigate the effect and mechanism of Hei Xiaoyaosan in preventing and treating Alzheimer's disease (AD) by activating autophagy through regulating the adenosine monophosphate-activated protein kinase (AMPK)/UNC-51 like autophagy activating kinase 1 (ULK1) signaling pathway. MethodsNinety 8-week-old male SPF-grade SD rats were selected and randomized into two groups: a blank control group (n=10) and a modeling group (n=80). From the modeling group, 10 rats were randomly assigned as a sham group (bilateral hippocampal injection of 1 μL normal saline), while the remaining 70 rats were injected with 1 μL Aβ1-42 solution bilaterally into the hippocampus to replicate the AD model. The Morris water maze test was conducted to screen the successfully modeled rats, which were then randomly allocated to the model, donepezil hydrochloride, 5-aminoimidazole-4-carboxamide 1-β-D-ribofuranoside (AICAR, an AMPK agonist), and high-, medium-, and low-dose Hei Xiaoyaosan groups, with 10 rats per group. After 42 days of drug intervention, the Morris water maze and open field tests were conducted to assess learning and memory abilities and motor function. Pathological changes in the hippocampal tissue were observed by Nissl staining, and autophagy-related pathological damage was examined via transmission electron microscopy (TEM). The expression of LC3 in the hippocampus was observed by immunofluorescence staining. The protein levels of AMPK, phosphorylate (p)-AMPK, ULK1, p-ULK1, p62, and autophagy related 7 (Atg7) were determined by Western blot, while the mRNA levels of AMPK and ULK1 were measured by Real-time polymerase chain reaction (Real-time PCR). ResultsCompared with the blank control group, the model group showed increased escape latency (P<0.01) and decreased platform crossings (P<0.01) on day 6 in the water maze test, reduced total distance traveled and average speed in the open field test (P<0.01), disarranged neurons with Nissl body loss and evident autophagic damage, weakened LC3 fluorescence signal (P<0.01), downregulated protein levels of p-AMPK, p-ULK1, and Atg7 and mRNA levels of AMPK and ULK1 in the hippocampus (P<0.01), and upregulated protein level of p62 (P<0.01). Compared with the model group, the positive drug group, high-dose Hei Xiaoyaosan group, and AICAR group showed decreased escape latency (P<0.05, P<0.01) and increased platform crossings (P<0.01) on day 6, and increased total distance traveled and average speed in the open field test (P<0.05). The positive drug group, high- and medium-dose Hei Xiaoyaosan groups, and the AICAR group showed alleviated cellular structural damage, regular neuronal arrangement, increased Nissl bodies, and orderly distribution of autophagosomes. Furthermore, the LC3 fluorescence intensity was enhanced in the positive drug group, high- and medium-dose Hei Xiaoyaosan groups, and the AICAR group (P<0.01). The positive drug group, high-dose Hei Xiaoyaosan group, and the AICAR group exhibited upregulated protein and mRNA levels of p-AMPK and p-ULK1 (P<0.05, P<0.01), upregulated protein level of Atg7 (P<0.05, P<0.01), and downregulated protein level of p62 (P<0.01). ConclusionHei Xiaoyaosan can improve learning and memory abilities and alleviate pathological status in the rat model of AD by regulating the AMPK/ULK1 signaling pathway, enhancing cellular autophagy, and repairing damaged nerve cells.

ObjectiveTo compare the differences in color, odor, coumarin content and microbial community composition of Angelicae Dahuricae Radix(ADR) during different drying processes, and to explore the correlation between changes in microbial community composition and changes in quality indexes of ADR. MethodsThe fresh ADR was processed at three drying temperatures(50, 70, 100 ℃) by drying and steaming cutting, semi-fresh cutting and drying, fresh cutting and drying, and sulfur fumigation methods. The color values of samples were extracted by Adobe Photoshop 2022 software and subjected to principal component analysis(PCA), electronic nose was used to identify the odor information of medicinal powders and subjected to loadings analysis, PCA, and linear discriminant analysis(LDA), and high performance liquid chromatography(HPLC) was used to determine the contents of five coumarins(bergapten, oxypeucedanin, imperatorin, phellopterin, isoimperatorin). The samples for microbial detection were taken from fresh dried samples, 50 ℃(dried and steamed cut, sulfur fumigated) samples, and 100 ℃(dried and steamed cut) samples when the water content was 50% and 14%, respectively. And the changes of microbial community composition during processing were determined by high-throughput sequencing method. The relationship between the changes of microbial community composition and the changes of odor, color and active component content of ADR during drying process was analyzed by Pearson correlation analysis. ResultsThe color quantification results showed that an increase in drying temperature led to the decrease of brightness value(L), and the increases of red-green value(a) and yellow-blue value(b), and the change of processing method had no obvious effect on the color of medicinal materials. The results of odor quantification showed that W1S, W2S, W5S, W2W and W1W sensor were sensitive to the odor changes of ADR and could be used to distinguish ADR decoction pieces from different processing methods. The results of HPLC showed that the coumarin content of ADR decreased with the increase of drying temperature and the delay of processing time, the optimal processing method was drying and steaming cutting method, and the optimal temperature was 50 ℃. High-throughput sequencing results showed that the dominant bacteria in ADR during processing were Achromobacter, Agrobacterium, Nocardioides, Mycobacterium and Enterobacter, the dominant fungi were Coprinopsis, Meyerozyma and Apiotrichum. The results of correlation analysis showed that the quality indexes of ADR were positively correlated with Agrobacterium, Mycobacterium in bacteria, Candida in fungi, and negatively correlated with Bacillus in bacteria. ConclusionThere are significant differences in the color, odor, coumarin content and microbial community composition of ADR in different drying processes, and the best drying method is drying and steaming cutting at 50 ℃. The relative abundance changes of 9 bacterial genera and 4 fungal genera are closely related to the quality formation of ADR during the drying process.
