Objective To investigate the prevalence of Paragonimus infection in freshwater crabs from selected areas of Yunnan Province, and to perform molecular characterization and phylogenetic analysis of the isolated parasites based on the internal transcribed spacer 2 (ITS2) and cytochrome c oxidase subunit I (COI) gene sequences. Methods Freshwater crabs were collected from both local markets and natural streams in Zhaotong City, Pu’er City, Dehong Dai and Jingpo Autonomous Prefecture, Baoshan City, Honghe Hani and Yi Autonomous Prefecture and Lincang City of Yunnan Province from May to August 2025. Paragonimus metacercariae were isolated using a sieve and sedimentation method. After morphological identification of the metacercariae, the infection rate and infection intensity of Paragonimus in freshwater crabs were calculated. Then genomic DNA was extracted from an individual metacercaria, and ITS2 and COI gene fragments were amplified using a PCR assay and sequenced. The obtained sequences were aligned with those available in the GenBank database. Genetic distances were calculated with the software MEGA 11.0 based on the Kimura 2-parameter model, and phylogenetic trees were built using the neighbour-joining method. Results A total of 600 freshwater crabs were collected, with 18 positive for Paragonimus metacercariae. The prevalence of Paragonimus infection was 12.00% (18/150) in freshwater crabs from Zhaotong City, while no Paragonimus infection was detected in crabs from other five prefectures (cities). Twenty metacercariae were recovered, with an overall infection intensity of 1.11 metacercariae per crab. Morphological observation revealed two types of Paragonimus metacercariae, including 19 resembling P. skrjabini, and 1 resembling P. paishuihoensis. Ten metacercariae of distinct morphotypes were randomly selected for molecular identification, and sequence alignment and phylogenetic analysis of ITS2 and COI genes identified 9 as P. skrjabini and 1 as P. paishuihoensis. The nine ITS2 gene sequences shared 98.34% to 100.00% homology with the reference sequence of P. skrjabini (GenBank accession number: KX129924.1), and the single ITS2 gene sequence showed 100.00% homology with the reference sequence of P. paishuihoensis (GenBank accession number: OM401939.1), while its COI sequence showed 98.80% homology with the reference sequence of P. paishuihoensis (GenBank accession number: AB679288.1). Phylogenetic analysis further confirmed that the 10 sequences were clustered separately into the clades of P. skrjabini and P. paishuihoensis. Conclusions This study reports the first detection of P. paishuihoensis in freshwater crabs from Zhaotong City, Yunnan Province, and confirms P. skrjabini as the dominant Paragonimus species in this region. Molecular identification and phylogenetic analysis based on ITS2 and COI genes are effective to distinguish Paragonimus species, which provides the scientific evidence for precise control of paragonimiasis in Yunan Province.

Objective:To evaluate the efficacy and safety of baricitinib combined with ruxolitinib cream in the treatment of progressive nonsegmental vitiligo.Methods:Clinical data were retrospectively collected from patients with progressive nonsegmental vitiligo in Boao Super Hospital. All the patients were treated with oral baricitinib daily (2 mg/day for patients weighing ≤ 50 kg; 4 mg/day for those > 50 kg) in combination with topical application of ruxolitinib cream twice daily for 24 consecutive weeks. Disease severity was assessed using the facial vitiligo area scoring index (F-VASI) and total body VASI (T-VASI) at baseline, week 12, and week 24. Adverse reactions were monitored throughout the treatment course.Results:Six patients with progressive nonsegmental vitiligo were collected, including 3 males and 3 females, aged 26 - 42 years, with the disease duration ranging from 0.5 to 25 years. At week 12, 3 patients achieved a 50% ~ < 75% improvement in facial vitiligo lesions (F-VASI 50), 1 patient achieved F-VASI 75 (75% ~ < 90% improvement), and 1 patient achieved T-VASI 50; at week 24, 4 patients achieved F-VASI 50, 1 patient achieved F-VASI 75, 1 patient achieved F-VASI 90 (≥ 90% improvement), and 3 patients achieved T-VASI 50. During the treatment, upper respiratory infection occurred in 1 patient, acne in 1 patient, pruritus in 2 patients, elevation of total cholesterol levels in 2 patients, and increase of high-density lipoprotein levels in 2 patients. No severe adverse events were observed during the treatment.Conclusion:The combination therapy with baricitinib and ruxolitinib cream may have potential efficacy and safety in the treatment of progressive nonsegmental vitiligo.

Objective To explore the potential profiles of symptom burden among stroke patients and to analyze the differences in the characteristics of different classes of stroke patients,providing references for clinical nursing practice.Methods A convenience sampling method was used to select 485 stroke patients treated at 4 tertiary-level general hospitals in Anhui Province from July to December 2024 as the study population.The general information questionnaire,Stroke Symptom Cluster Scale,Personal Mastery Scale,and Cognitive Reserve Index questionnaire.Latent profile analysis was employed to explore the categories of symptom burden among stroke patients,and multiple logistic regression was used to assess the influence factors of each category.Results A total of 456 valid questionnaires were collected,with a valid response rate of 94.02％.Symptom burden among stroke patients can be divided into 4 latent profiles:low symptom burden group(69.08％),multiple symptom burden group(8.12％),moderate burden-physical activity impairment group(11.18％),and moderate burden-emotional and cognitive language impairment group(11.62％).The patient's age,number of stroke episodes,number of chronic diseases,systemic inflammation response index,personal mastery,and cognitive reserve were the factors influencing the latent profiles of symptom burden in stroke patients(P＜0.05).Conclusion The symptom burden of stroke patients shows significant heterogeneity.Medical staff can develop targeted nursing interventions based on the category characteristics and influencing factors of the symptom burden in stroke patients.

Chest drains are often placed after lung cancer surgery, but the tube often leads to postoperative pain and affects recovery. With the popularization of the concept of enhanced recovery after surgery(ERAS), we urgently need to reform the application of chest drains. In this article, we will discuss the latest research progress on drain thickness, placement and suture methods, and perioperative management, aiming to provide reference for clinical application.

Adolescent idiopathic scoliosis(AIS)is a complex three-dimensional deformity involving coronal,sagittal,and axial planes,with a prevalence that should not be overlooked.With advancements in technology and in-depth research,an increasing number of hospitals and physicians are exploring standardized diagnostic and treatment approaches for AIS.Comprehensive and in-depth understanding is required for AIS,including its etiology,screening and diagnosis,classification,assessment and examination,treatment options,exploration of current focus,and evaluation of quality of life.Such understanding ensures that the diagnostic and treatment are scientific,standardized,and timely.Based on the principles of evidence-based medicine,a consensus on the diagnosis and treatment of AIS is reached after multiple discussions among spinal surgery experts,aiming to provide reference and guidance for clinical practice.

OBJECTIVE To systematically evaluate the repair strategies for temporal bone-parotid composite defects,compare the clinical applicability of local muscle flaps and free flaps,and provide references for optimizing the reconstruction of complex head and neck defects.METHODS We retrospectively analyzed the medical records of 17 patients with postoperative defects in the temporal bone-parotid region treated at Beijing Tongren Hospital,Capital Medical University,between January 2018 and June 2023.There were 11 males and 6 females,with a median age of 58 years(range:42-72 years).All patients had undergone radical resection.Defects were reconstructed with local flaps in 13 cases(temporalis muscle flap,n=6;sternocleidomastoid flap,n=3;submental platysma flap,n=2;submental island flap,n=2)and with free flaps in 4 cases(anterolateral thigh fascial flap,n=1;anterolateral thigh flap,n=1;free abdominal adipofascial flap,n=2).RESULTS The primary diseases of the 17 patients were malignant tumors of the external auditory canal and parotid gland(6 cases of squamous cell carcinoma,6 cases of adenoid cystic carcinoma,and 3 cases of ductal carcinoma).All flaps survived completely.One patient with temporalis muscle flap repair developed postoperative wound infection,which healed after debridement and dressing change.The median follow-up period was 16 months(4-29 months).Two cases(11.8%)of external auditory canal squamous cell carcinoma had local recurrence,one case(5.9%)of parotid ductal carcinoma developed pulmonary metastasis 9 months after surgery and died at 15 months.The remaining 14 cases(82.4%)were tumor-free survivors.Functional evaluation showed that the local tissue flap group had a shorter repair time,but was limited by muscle flap rotation arc;the free flap group could accurately match the defect shape,but the surgical time was prolonged to 3.5-4.5 hours.Fourteen cases(82.4%)received postoperative adjuvant radiotherapy.None of the tissue flaps developed radiation necrosis after radiotherapy.CONCLUSION Temporal bone-parotid composite defects need to balance the dual requirements of surgical cavity coverage and cosmetic repair.Local muscle flaps are easy to operate and have reliable blood supply,suitable for small and medium-sized defects;free tissue flaps have better shape adaptability in complex three-dimensional defect reconstruction,but require microsurgical technical support.The repair plan should be comprehensively decided based on the defect range,vascular conditions,and radiotherapy plan.The data of this group confirmed that both techniques can achieve stable therapeutic effects.

Acute kidney injury (AKI) has high morbidity and mortality, but effective clinical drugs and management are lacking. Previous studies have suggested that macrophages play a crucial role in the inflammatory response to AKI and may serve as potential therapeutic targets. Emerging evidence has highlighted the importance of forkhead box protein O1 (FoxO1) in mediating macrophage activation and polarization in various diseases, but the specific mechanisms by which FoxO1 regulates macrophages during AKI remain unclear. The present study aimed to investigate the role of FoxO1 in macrophages in the pathogenesis of AKI. We observed a significant upregulation of FoxO1 in kidney macrophages following ischemia-reperfusion (I/R) injury. Additionally, our findings demonstrated that the administration of FoxO1 inhibitor AS1842856-encapsulated liposome (AS-Lipo), mainly acting on macrophages, effectively mitigated renal injury induced by I/R injury in mice. By generating myeloid-specific FoxO1-knockout mice, we further observed that the deficiency of FoxO1 in myeloid cells protected against I/R injury-induced AKI. Furthermore, our study provided evidence of FoxO1's pivotal role in macrophage chemotaxis, inflammation, and migration. Moreover, the impact of FoxO1 on the regulation of macrophage migration was mediated through RhoA guanine nucleotide exchange factor 1 (ARHGEF1), indicating that ARHGEF1 may serve as a potential intermediary between FoxO1 and the activity of the RhoA pathway. Consequently, our findings propose that FoxO1 plays a crucial role as a mediator and biomarker in the context of AKI. Targeting macrophage FoxO1 pharmacologically could potentially offer a promising therapeutic approach for AKI.

Intentional tooth replantation (ITR) is an advanced treatment modality and the procedure of last resort for preserving teeth with inaccessible endodontic or resorptive lesions. ITR is defined as the deliberate extraction of a tooth; evaluation of the root surface, endodontic manipulation, and repair; and placement of the tooth back into its original socket. Case reports, case series, cohort studies, and randomized controlled trials have demonstrated the efficacy of ITR in the retention of natural teeth that are untreatable or difficult to manage with root canal treatment or endodontic microsurgery. However, variations in clinical protocols for ITR exist due to the empirical nature of the original protocols and rapid advancements in the field of oral biology and dental materials. This heterogeneity in protocols may cause confusion among dental practitioners; therefore, guidelines and considerations for ITR should be explicated. This expert consensus discusses the biological foundation of ITR, the available clinical protocols and current status of ITR in treating teeth with refractory apical periodontitis or anatomical aberration, and the main complications of this treatment, aiming to refine the clinical management of ITR in accordance with the progress of basic research and clinical studies; the findings suggest that ITR may become a more consistent evidence-based option in dental treatment.

Objective To study the predictive value of adenosine monophosphate-activated protein kinase(AMPKα)and hepatocyte nuclear factor 4(HNF4)expression for local recurrence and distant metastasis after laparoscopic radical gastrectomy for gastric cancer.Methods Two hundred and ninety-four patients who underwent laparoscopic radical gastric cancer surgery admitted to Suining Central Hospital from January 2020 to August 2022 were selected.These patients were categorized into a recurrence and metastasis group(n=59)and a non-recurrence and non-metastasis group(n=235)based on postoperative local recurrence and distant metastasis.Gastric cancer tissue specimens obtained from surgical resection were used to detect and compare the cancer tissues of AMPKα mRNA and HNF4 mRNA between the two groups,and the data were statistically analyzed.Results The AMPKα mRNA and HNF4 mRNA in the recurrence and metastasis group were lower than those in the non recurrence and metastasis group(P<0.05);the point-biserial correlation showed that AMPKα mRNA(r=-0.816)and HNF4 mRNA(r=-0.803)were negatively correlated with postoperative local recurrence and distant metastasis(P<0.001),and the net correlation analysis showed that this relationship still existed after excluding confounding factors(P<0.001).Logistic regression analysis showed that AMPKα mRNA and HNF4 mRNA were postoperative local recurrence and distant metastasis related influencing factors(P<0.001);the interaction analysis showed that AMPKα mRNA and HNF4 mRNA were in a super multiplication model,and the decrease of HNF4 mRNA had a positive interaction effect on the decrease of AMPKα mRNA(P<0.05);the AUC of AMPKα mRNA+HNF4 mRNA was higher than that of AMPKα mRNA or HNF4 mRNA(Z=4.261,4.275,P<0.05).Conclusion Co-mbined detection of AMPKα and HNF4 expression can predict the risk of local recurrence and distant metastasis after laparoscopic radical gastrectomy for gastric cancer.
