Background: Maturity-onset diabetes of the young (MODY) due to variants of hepatocyte nuclear factor 1-beta (HNF1β) (MODY5) has not been well studied in the Chinese population. This study aimed to estimate its prevalence and evaluate the application of a clinical screening method (Faguer score) in Chinese early-onset diabetes (EOD) patients. Methods: Among 679 EOD patients clinically diagnosed with type 2 diabetes mellitus (age at diagnosis ≤40 years), the exons of HNF1β were sequenced. Functional impact of rare variants was evaluated using a dual-luciferase reporter system. Faguer scores ≥8 prompted multiplex ligation-dependent probe amplification (MLPA) for large deletions. Pathogenicity of HNF1β variants was assessed following the American College of Medical Genetics and Genomics (ACMG) guidelines. Results: Two rare HNF1β missense mutations (E105K and G454R) were identified by sequencing in five patients, showing functional impact in vitro. Another patient was found to have a whole-gene deletion by MLPA in 22 patients with the Faguer score above 8. Following ACMG guidelines, six patients carrying pathogenic or likely pathogenic variant were diagnosed with MODY5. The estimated prevalence of MODY5 in Chinese EOD patients was approximately 0.9% or higher. Conclusion MODY5 is not uncommon in China. The Faguer score is helpful in deciding whether to perform MLPA analysis on patients with negative sequencing results.

OBJECTIVE: To evaluate the effectiveness of early internal fixation combined with free anterolateral thigh perforator flap (ALTPF) transplantation in the treatment of open ankle fracture-dislocation. METHODS: A retrospective analysis was performed on the clinical data of 13 patients with open ankle fracture-dislocation who were admitted and met the inclusion criteria between January 2021 and May 2024. Among them, there were 9 males and 4 females, with the ages ranging from 23 to 61 years (mean, 45.3 years). Fracture types included 5 cases of simple medial or lateral malleolar fracture-dislocation, 7 cases of bimalleolar (medial and lateral) fracture-dislocation, and 1 case of trimalleolar fracture-dislocation. Additionally, 3 cases were complicated with bone defects (1 medial malleolus defect and 2 lateral malleolus defects). All injuries were classified as type ⅢB according to the Gustilo-Anderson classification for open fractures. The size of wound defects ranged from 7 cm×5 cm to 18 cm×12 cm. The time from injury to surgery was 2-20 hours (mean, 4 hours). All patients underwent emergency thorough debridement upon admission. The fracture-dislocation was temporarily stabilized with an external fixator, and the wound was covered with antibiotic-impregnated bone cement sheets or vacuum sealing drainage. Definitive internal fixation of the fracture and free ALTPF transplantation were performed 5-7 days after the initial emergency procedure. Postoperatively, wound healing, flap survival, and fracture union were monitored. At last follow-up, clinical outcomes were assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score. RESULTS: All 13 patients were followed up 6-24 months (mean, 8.2 months). All flaps survived completely, and all fractures achieved union, with an union time of 3-11 months (mean, 5.5 months). One patient developed a superficial infection at the wound margin, which healed after regular dressing changes and drainage. No internal fixation-related complication (e.g., deep infection, implant loosening, or secondary ankle instability) were observed. At last follow-up, the total AOFAS ankle-hindfoot score was 78.6±13.5, with 3 excellent, 7 good, 2 fair, and 1 poor cases, yielding an excellent and good rate of 76.9%. CONCLUSION Early internal fixation combined with ALTPF transplantation for open ankle fracture-dislocation can shorten the treatment course and maximize the recovery of ankle joint function.

OBJECTIVE: To explore the effect of acupuncture therapy on dysphagia in patients with Parkinson's disease. METHODS: This randomized controlled study lasted 42 days and included 112 patients with Parkinson's disease and dysphagia. Participants were randomly assigned to the experimental and control groups (56 cases each group) using the completely randomized design, all under routine treatment. The experimental group was given acupuncture therapy. The primary outcome was Penetration-Aspiration Scale (PAS). The secondary outcomes were (1) Standardized Swallowing Assessment (SSA), and (2) nutritional status including body mass index (BMI), serum albumin, prealbumin, and hemoglobin. Adverse events were recorded as safety indicators. RESULTS: One participant quitted the study midway. There were no significant differences in baseline assessment (P>0.05). After treatment, both groups showed significant improvement in PAS, SSA and nutritional status except for BMI of the control group. There were significant differences between the two groups in the PAS for both paste and liquid, SSA (25.18±8.25 vs. 20.84±6.92), BMI (19.97±3.34 kg/m²vs. 21.26 ±2.38 kg/m²), serum albumin (35.16 ±5.29 g/L vs. 37.24 ±3.98 g/L), prealbumin (248.33 ±27.72 mg/L vs. 261.39 ±22.10 mg/L), hemoglobin (119.09±12.53 g/L vs. 126.67±13.97 g/L) (P<0.05). There were no severe adverse events during the study. CONCLUSION: The combination of routine treatment and acupuncture therapy can better improve dysphagia and nutritional status in patients with Parkinson's disease, than routine treatment solely.

Ethanol detection plays an important role in food industry,environmental monitoring,medical health monitoring,prevention of drunk driving,etc.The development of low-cost,high-performance ethanol sensors has important application value.In this study,a ZnO/FeS nano heterojunction ethanol sensor was prepared on commercial ceramic silver electrode substrate.The sensing characteristics of the sensor for ethanol gas were systematically studied.The results showed that ZnO had a nanowire structure,and the FeS was coated on the ZnO nanowire in the form of nanosheets.The sensor performed well for ethanol detection in environments with relative humidity ranging from 30%to 60%,with a detection range from 0.2 mg/m3 to 50 mg/m3.At the optimum operating temperature of 300℃,the response of ZnO/FeS nano heterojunction sensor to 50 mg/m3 ethanol was 15.6,the response time was 5.0 s,and the detection limit was as low as 0.101 mg/m3,which was obviously better than that of commercial ethanol sensor.This sensor was highly selective for ethanol compared to other gases such as CO,NH3,acetone,etc,and could steadily work for 30 days.The fabricated sensor had good development potential in the field of low-cost and high-performance ethanol gas detection.

OBJECTIVE To systematically evaluate the efficacy and safety of different induction regimens for AIDS complicated with cryptococcal meningitis.METHODS PubMed,Embase,Cochranre library,Web of science,CNKI,Wanfang,Weipu and other databases were systematically searched to collect randomized controlled trials related to the induction treatments of AIDS complicated with cryptococcal meningitis.The search was limited to Oct.2024.The Cochrane risk of bias evaluation system was used to evaluate the quality of the literature,and Stata 15.1 and Revman 5.3 software were used for network meta-analysis.RESULTS A total of 17 randomized controlled trials involving 3,281 patients were included.The result of network meta-analysis showed that the treatment regi-men with the lowest early mortality was the short-course of amphotericin B+fluconazole+flucytosine;the regi-men with the lowest late mortality was a single high-dose amphotericin B liposome;the regimen with the highest 14-day fungal clearance rate was amphotericin B+flucytosine;the regimen with the lowest incidence of grade 3+4 anemia was a single high-dose amphotericin B liposome;the regimen with the lowest incidence of grade 3+4 re-nal injury was amphotericin B liposome;the regimen with the lowest incidence of grade 3-4 hypokalemia was flu-conazole+flucytosine.CONCLUSION According to the comprehensive analysis of various indices,there is good efficacy and safety for the inclusion of short-course amphotericin B regimen and single high-dose amphotericin B li-posome as induction period therapy for AIDS complicated with cryptococcal meningitis.
