OBJECTIVE To investigate the effects and mechanisms of Lycium ruthenicum Murr. in improving sleep. METHODS Network pharmacology was employed to identify the active components of L. ruthenicum and their associated disease targets, followed by enrichment analysis. A caffeine‑induced zebrafish model of sleep deprivation was established , and the zebrafish were treated with L. ruthenicum Murr. extract (LRME) at concentrations of 0.1, 0.2 and 0.4 mg/mL, respectively; 24 h later, behavioral changes of zebrafish and pathological alterations in brain neurons were subsequently observed. The levels of inflammatory factors [interleukin-6 (IL-6), IL-1β, IL-10, tumor necrosis factor-α (TNF-α)], oxidative stress markers [superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), catalase (CAT)], and neurotransmitters [5- hydroxytryptamine (5-HT), γ-aminobutyric acid (GABA), glutamic acid (Glu), dopamine (DA), and norepinephrine (NE)] were measured. The protein expression levels of protein kinase B1 (AKT1), phosphorylated AKT1 (p-AKT1), epidermal growth factor receptor (EGFR), B-cell lymphoma 2 (Bcl-2), sarcoma proto-oncogene,non-receptor tyrosine kinase (SRC), and heat shock protein 90α family class A member 1 (HSP90AA1) in the zebrafish were also determined. RESULTS A total of 12 active components and 176 intersecting disease targets were identified through network pharmacology analysis. Among these, apigenin, naringenin and others were recognized as core active compounds, while AKT1, EGFR and others served as key targets; EGFR tyrosine kinase inhibitor resistance signaling pathway was identified as the critical pathway. The sleep improvement rates in zebrafish of LRME low-, medium-, and high-dose groups were 54.60%, 69.03% and 77.97%, 开发。E-mail:hjp_yft@163.com respectively, while the inhibition ratios of locomotor distance were 0.57, 0.83 and 0.95, respectively. Compared with the model group, the number of resting counts, resting time and resting distance were significantly increased/extended in LRME medium- and high-dose groups (P<0.05). Neuronal damage in the brain was alleviated. Additionally, the levels of IL-6, IL-1β, TNF-α, MDA, Glu, DA and NE, as well as the protein expression levels of AKT1, p-AKT1, EGFR, SRC and HSP90AA1, were markedly reduced (P<0.05), while the levels of IL-10, SOD, GSH-Px, CAT, 5-HT and GABA, as well as Bcl-2 protein expression, were significantly elevated (P<0.05). CONCLUSIONS L. ruthenicum Murr. demonstrates sleep-improving effects, and its specific mechanism may be related to the regulation of inflammatory responses, oxidative stress, neurotransmitter balance, and the EGFR tyrosine kinase inhibitor resistance signaling pathway.

ObjectiveTo detect the proportion of splenic follicular helper T (Tfh) cells and their functionally related cytokine expression levels in the incomplete embryo implantation disorder (EID) model mice, and to explore the immunological mechanism of Tfh in infertility caused by embryo implantation disorder. MethodsSixteen female Kunming mice were randomly divided into two groups, with eight mice in each group. On day 4 of pregnancy, an incomplete EID mouse model was established by oral gavage of mifepristone suspension, while an equal volume of saline was administered to the control group. On day 8 of pregnancy, the mice were euthanized. Flow cytometry was used to detect the levels of Tfh cells in the spleen lymphocytes of both incomplete EID mice and normal control mice. qRT-PCR was performed to measure the mRNA levels of B-cell lymphoma 6 (Bcl-6) and C-X-C chemokine receptor type 5 protein (CXCR5) in the spleen lymphocytes of both groups. Western blot was employed to assess the protein expression levels of Bcl-6 and CXCR5 in the spleen lymphocytes of both groups. Serum levels of interleukin-4 (IL-4), IL-6, and IL-21 were measured by ELISA. Immunohistochemistry (IHC) was used to observe the expression levels of progesterone receptor (PR), Bcl-6, and CXCR5 proteins in the uterine endometrial tissue of mice in both groups. ResultsIncomplete-type EID mice had a reduced number of embryo implantation points and reduced endometrial PR expression. Flow assay results showed that the proportion of CD4+CXCR5+Tfh cells in splenic lymphocytes of incomplete-type EID mice was significantly higher than that of normal controls (P<0.05). Compared with the normal control group, Bcl-6 and CXCR5 mRNA levels and protein levels were elevated in splenic lymphocytes of incomplete EID mice, with statistically significant differences (P<0.05); serum IL-4, IL-6, and IL-21 levels were elevated in incomplete EID mice, and Bcl-6 and CXCR5 proteins in the endometrium were significantly elevated (P<0.05). ConclusionThe increase of Tfh cells and their associated cytokines Bcl-6 and CXCR5 is associated with the development of incomplete EID, and may be involved in the development of female immune infertility.

OBJECTIVE To investigate the efficacy and safety of omadacycline in the treatment of macrolide-unresponsive Mycoplasma pneumoniae pneumonia (MUMPP) in children. METHODS A retrospective study was conducted on children aged 1-18 years old with MUMPP who were hospitalized in the Department of Pediatrics, the First Affiliated Hospital of Xinjiang Medical University from January 2022 to June 2025. According to the selection of secondary antibiotics after 72 h of initial treatment with macrolides, they were divided into the omadacycline group and the doxycycline group. Based on conventional treatment, children in the omadacycline group were given intravenous infusion of 2.4 mg/kg (once daily) of omadacycline tosylate, while children in the doxycycline group were given oral doxycycline hydrochloride tablets at 2 mg/kg (twice daily). The efficacy and safety were compared between the two groups of pediatric patients. Univariate analysis and multivariate Logistic regression analysis were performed on clinical efficacy, and subgroup analysis along with multiple sensitivity analyses were conducted to verify the robustness of the conclusions. RESULTS A total of 284 children with MUMPP were included in this study, with 142 in the omadacycline group and 142 in the doxycycline group. In terms of efficacy, although the hospitalization time of children in the omadacycline group was longer than that in the doxycycline group ( P <0.05), the lung lesion absorption rate and clinical efficacy were significantly higher or better than those in the doxycycline group ( P <0.05). The results of multivariate Logistic regression analysis showed that medication (OR=5.300, 95%CI: 2.526-11.123), length of hospital stay (OR=1.348, 95%CI: 1.167-1.556), and medication duration (OR=1.422, 95%CI: 1.169-1.729) were influencing factors of clinical efficacy ( P <0.05). The subgroup analysis results showed that the clinical efficacy of omadacycline was significantly better than that of doxycycline in all subgroups ( P <0.05). The results of multiple sensitivity analysis showed that the regression coefficients B of the four models (gradually adjust variables) before and after inverse probability of treatment weighting were significantly greater than 1 ( P <0.05). In terms of safety, there was no statistically significant difference in the inci dence of adverse drug reactions between the two groups of patients ( χ 2 =0.447, P =0.504). CONCLUSIONS In the case of hospitalization and prolonged medication, the efficacy of omadacycline in treating childhood MUMPP is superior to that of doxycycline, and its safety is good.

OBJECTIVE To investigate the therapeutic effect and mechanism of Qiwei dongqingye powder (QDP) on bronchial asthma in mice. METHODS The mice were divided into blank group (normal saline), model group (normal saline), dexamethasone group (2 mg/kg), and QDP low-, medium-, and high-dose groups (200, 400, 800 mg/kg), with 14 mice in each group. Except for the blank group, mice in all other groups were given ovalbumin via intraperitoneal injection followed by aerosol inhalation to induce a bronchial asthma model. During the modeling process, mice in each group were administered corresponding drug solutions or normal saline intragastrically/intraperitoneally. After the last medication, the number of cells in the bronchoalveolar lavage fluid (BALF) of the mice was observed and counted; the pathological changes of the bronchus and lung tissue were observed; the levels of malondialdehyde (MDA), nitric oxide (NO), total superoxide dismutase (T-SOD), and glutathione peroxidase (GSH-Px) in the lung tissue of the mice were determined, and the level of interleukin-17 (IL-17) in the BALF and serum was determined. Transcriptomics was employed to predict and validate the mechanism of action of QDP against bronchial asthma. RESULTS Compared with the model group, the total cell count, neutrophil count, lymphocyte count, and macrophage counts in the BALF of the QDP high-dose group were all significantly reduced ( P <0.05); the levels of MDA and NO in the lung tissue, and the levels of IL-17 in the BALF and serum were all decreased significantly ( P <0.05); the levels of T-SOD and GSH-Px were significantly increased ( P <0.05); the arrangement of lung tissue cells tended to normalize, with reduced infiltration of inflammatory cells and decreased exfoliation of bronchial simple columnar epithelial cells. The transcriptomic results revealed that the differentially expressed genes were B-cell receptor signaling pathway, nuclear factor κB (NF-κB) signaling pathway, ferroptosis signaling pathway, and others. Further validation revealed that, compared with the model group, the expression levels of NF-κB p65 and chemokine ligand 20, as well as the phosphorylation level of NF-κB inhibitor protein α, were significantly decreased in the lung tissues of the mice in all QDP groups ( P <0.05). Conversely, the protein expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase 1 (HO-1) were significantly increased ( P <0.05). CONCLUSIONS QDP can effectively alleviate bronchial asthma by inhibiting the NF-κB signaling pathway, activating the Nrf2/HO-1 signaling pathway, regulating oxidative stress, and reducing inflammatory responses.

Background Methicillin-resistant Staphylococcus aureus (MRSA) is an important pathogen for both human bloodstream infections and mastitis in cows. However, little attention has been paid to the cross-host transmission of MRSA from cows to high-risk groups in China. Objective To determine the MRSA colonization rates among dairy cows and dairy farm workers in Xinjiang, identify the antibiotic resistance profiles and molecular characteristics of the isolates, and provide scientific evidence for the formulation of targeted infection control strategies. Method A cross-sectional survey combined with laboratory pathogen analysis was conducted. From June to August 2024, large-scale dairy farms in Xinjiang region were selected as study sites. Nasal swabs (n=96) and skin swabs (n=39) were collected from workers, and bovine nasal swab samples (n=109) were collected simultaneously. All samples were subjected to MRSA isolation, cultivation, and identification, followed by antibiotic susceptibility testing to characterize resistance phenotypes. Staphylococcus aureus protein A (Spa) typing was performed to determine strain genotypes and elucidate MRSA colonization rates and molecular epidemiological patterns. Results A total of 35 MRSA strains was successfully isolated from 244 samples. The MRSA colonization rates among dairy farm workers and dairy cows were 20.83% (20/96) and 12.84% (14/109), respectively, with an overall isolation rate of 14.34% (35/244). Among the workers, the nasal colonization rate was 16.67% (16/96), and the skin colonization rate was 12.82% (5/39). One worker exhibited MRSA colonization at multiple body sites. All MRSA strains were resistant to cefoxitin (100%, 35/35). The resistance rates to erythromycin and clindamycin were 42.86% (15/35) and 34.29% (12/35), respectively. Thirteen strains showed a multidrug-resistant phenotype, whereas all strains were susceptible to vancomycin. The MRSA isolates exhibited high genetic diversity, with 13 Spa types identified, among which t441 was the most prevalent (8 strains). Both t441 and t034 types were detected in samples from both the dairy cows and their handlers. These two Spa types also carried and stably inherited specific resistance combinations, including erythromycin–clindamycin–cefoxitin and ciprofloxacin–erythromycin–clindamycin–gentamicin–cefoxitin–tetracycline, and a statistically significant association was also observed between the two resistance profiles and the bacterial types (P < 0.001). In addition, one novel Spa type strain was identified. Conclusion MRSA colonization rates among dairy cows and dairy farm workers in Xinjiang are relatively high, with evidence of multi-site colonization. The isolates exhibit high levels of multidrug resistance and genetic diversity, indicating a potential risk of cross-host transmission.

Objective To compare the cost and efficacy of ambulatory versus hospitalized surgery for lung tumor patients. Methods Two researchers independently conducted a computer search on February 14, 2025, in databases including CNKI, PubMed, Web of Science, Ovid Medline, Cochrane Library, and Wanfang Database, with the search period covering from the inception of these databases to February 2025. The outcome indicators were postoperative complication rate, length of hospital stay, hospitalization costs, et al. For the included randomized controlled trials and non-randomized controlled trials, we used the Cochrane risk of bias assessment tool and the Newcastle Ottawa Scale (NOS) respectively to evaluate the quality of the literature, and extracted data from the included studies for meta-analysis using RevMan 5.4 and Stata 18.0. Results A total of 12 researches were ultimately included, consisting of 2 randomized controlled trials, 2 prospective cohort studies, and 8 retrospective cohort studies, involving a total of 76 403 patients. All researches were evaluated as high-quality. Meta-analysis showed that the ambulatory surgery group had advantages over the hospitalized surgery group in terms of operation time [MD=−21.07, 95%CI (−30.55, −11.58), P<0.001], length of hospital stay [MD=−2.17, 95%CI (−3.25, −1.09), P<0.001], hospitalization costs [SMD=−1.22, 95%CI (−2.18, −0.26), P=0.01], and overall postoperative complications [OR=0.48, 95%CI (0.32, 0.74), P<0.001]. There was no statistically significant difference between the two groups in terms of postoperative hoarseness [OR=0.62, 95%CI (0.24, 1.61), P=0.33] and postoperative chylothorax [OR=0.27, 95%CI (0.07, 1.07), P=0.06]. Conclusion Compared to conventional hospitalized lung tumor resection, ambulatory lung tumor resection can significantly reduce the patient’s surgery and hospital stay time, decrease hospitalization costs, and reduce the incidence of postoperative complications. Ambulatory surgery can improve hospital efficiency while reducing the economic burden on patients. It is worthy of further promotion and application.

Hepatitis D virus (HDV), as a defective virus, relies on the envelope protein of hepatitis B virus (HBV) to complete replication and transmission. Chronic hepatitis B (CHB) patients comorbid with HDV infection may experience significant acceleration of liver disease progression and a significantly higher risk of serious complications such as liver cirrhosis and hepatocellular carcinoma (HCC) compared with the patients with CHB alone, which poses a serious threat to the life and health of patients. At present, the coverage rate of HDV screening needs to be improved, and some patients with HBV/HDV co-infection have not been found in time. Therefore, strengthening the understanding of HDV among clinicians, expanding the scope of HDV screening, identifying patients with infection in a timely manner, and performing standardized antiviral therapy and long-term follow-up management are of great significance for improving the prognosis of patients, reducing disease burden, improving the quality of life of patients, and achieving the global goal of “eliminating viral hepatitis as a public health threat by 2030”.

OBJECTIVE To form an expert consensus on the clinical application of parenteral direct thrombin inhibitors (DTIs) in patients during the perioperative period. METHODS Led by Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital (the Affiliated Hospital of UESTC), a multidisciplinary working group was established. Through literature review and the Delphi method, clinical questions related to the rational perioperative use of parenteral DTIs were identified. A structured design was adopted using the “Population-Intervention-Comparison-Outcome” framework; systematic searches were conducted in CNKI, Medline, Embase and other databases. Relevant evidence from randomized controlled trials and cohort studies was included and synthesized. Evidence quality was assessed using the Grades of Recommendations Assessment,Development and Evaluation (GRADE) approach, and recommendations were formulated through multiple rounds of Delphi surveys and expert consensus meetings. RESULTS &CONCLUSIONS Seven recommendations (each with an expert consensus rate exceeding 90%) on the use of parenteral DTIs in perioperative patients were developed. These recommendations specify drug selection, dosing ranges, key monitoring points, and safety management strategies for parenteral DTIs in various scenarios, including the perioperative period of ventricular assist device implantation, the perioperative period of cardiac surgery, perioperative patients with lower-extremity atherosclerotic disease, the perioperative period of percutaneous coronary intervention in patients with acute coronary syndrome, the perioperative period of carotid artery stenting in patients with carotid stenosis, the perioperative period of patients with right heart thrombosis, and patients who develop related thrombosis and dysfunction after a central venous catheter insertion. In addition, warning and management pathways for perioperative bleeding and thrombotic events were proposed. This expert consensus, which is formulated based on the best available evidence, provides evidence-based guidance for standardized and individualized use of parenteral DTIs in perioperative period.

Objective To explore the causal relationships between 13 micronutrients (copper, selenium, zinc, calcium, folate, iron, magnesium, vitamin A, vitamin B6, vitamin B12, vitamin C, vitamin D, and vitamin E) and risk of tuberculosis (TB) through a two-sample Mendelian randomization (MR) study. Methods The Genome-Wide Association Study (GWAS) data about micronutrients and TB were obtained from the IEU Open GWAS and FinnGen Biobank, and Bayesian Weighted Mendelian Randomization (BWMR) and Inverse Variance Weighted (IVW) methods were employed to explore the causal relationship between micronutrients and risk of TB. The robustness and reliability of the results were assessed through horizontal pleiotropy tests, heterogeneity tests, and leave-one-out sensitivity analyses. Results The BWMR results indicated that iron (OR = 0.40, 95% CI : 0.20- 0.79, P = 0.008) and vitamin C (OR = 0.42, 95% CI : 0.20 - 0.87, P = 0.019) were protective factors against TB infection, while no causal relationships were found between other micronutrients with TB infection. The IVW method produced consistent results with BWMR. The results for other micronutrients were robust and reliable (P > 0.05), except for calcium-related Instrumental Variables (IVs), which exhibited heterogeneity (P < 0.05). Conclusion Iron and vitamin C may play a protective role in reducing the risk of TB, whereas the remaining micronutrients show no significant causal relationship with TB.

AIM:To investigate the effects of high-altitude hypoxic exposure on retinal injury and the associated changes in oxidative stress-related indicators in rats. METHODS: Twenty-four healthy male Sprague-Dawley(SD)rats were randomly divided into a plain group and a high-altitude group, with 12 rats(24 eyes)in each group. Rats in the plain group were housed under normoxic conditions in an SPF-grade animal facility, whereas rats in the high-altitude group were placed in a special environmental chamber simulating an altitude of 6 000 m for 7 d. Optical coherence tomography(OCT)was used to assess retinal layer architecture and quantify retinal thickness. Hematoxylin-eosin(HE)staining was performed to observe retinal histopathological changes. Immunofluorescence(IF)was used to detect the expression of hypoxia-inducible factor-1α(HIF-1α)in retinal tissue. Transmission electron microscopy(TEM)was applied to examine the ultrastructure of retinal ganglion cells(RGCs). Enzyme-linked immunosorbent assay(ELISA)was used to measure the levels of malondialdehyde(MDA), total superoxide dismutase(T-SOD), and reduced glutathione(GSH)in retinal tissue. In addition, intracellular reactive oxygen species(ROS)levels in retinal tissue were assessed using the 2',7'-dichlorodihydrofluorescein diacetate(DCFH-DA)fluorescent probe. RESULTS: OCT examination revealed disorganized retinal architecture in the high-altitude group, with increased inner and middle ring thickness and decreased outer ring thickness compared with the plain group(all P<0.05). HE staining showed varying degrees of retinal layer damage, blurred layer boundaries, loosely arranged RGCs, and partial cellular necrosis in the high-altitude group. IF analysis demonstrated significantly increased HIF-1α expression in the inner nuclear layer of the high-altitude group(P<0.01). TEM revealed mitochondrial swelling, disrupted cristae, and reduced matrix electron density in RGCs of the high-altitude group. ELISA and fluorescence probe assays showed significantly elevated MDA levels and ROS fluorescence intensity, accompanied by decreased T-SOD and GSH levels in the retinal tissue of the high-altitude group(all P<0.05). CONCLUSION: Exposure to a high-altitude hypoxic environment induces marked morphological and ultrastructural damage in the rat retina and significantly enhances oxidative stress, suggesting that oxidative stress may play a critical role in retinal injury induced by high-altitude hypoxia.
