PURPOSE: To assess the relationship between dislocation and functional outcomes in supination-external rotation (SER) ankle fractures. METHODS: A retrospective case series study was performed on patients with ankle fractures treated surgically at a large trauma center from January 2015 to December 2021. The inclusion criteria were young and middle-aged patients of 18 - 65 years with SER ankle fractures that can be classified by Lauge-Hansen classification and underwent surgery at our trauma center. Exclusion criteria were serious life-threatening diseases, open fractures, fractures delayed for more than 3 weeks, fracture sites ≥ 2, etc. Then patients were divided into dislocation and no-dislocation groups. Patient demographics, injury characteristics, surgery-related outcomes, and postoperative functional outcomes were collected and analyzed. The functional outcomes of SER ankle fractures were assessed postoperatively at 1-year face-to-face follow-up using the foot and ankle outcome score (FAOS) and American Orthopedic Foot and Ankle Society ankle hindfoot score and by 2 experienced orthopedic physicians. Relevant data were analyzed using SPSS version 22.0 by Chi-square or t-test. RESULTS: During the study period, there were 371 ankle fractures. Among them, 190 (51.2%) were SER patterns with 69 (36.3%) combined with dislocations. Compared with the no-dislocation group, the dislocation group showed no statistically significant differences in gender, age composition, fracture type, diabetes, or smoking history, preoperative waiting time, operation time, and length of hospital stay (all p > 0.05), but a significantly higher Lauge-Hansen injury grade (p < 0.001) and syndesmotic screw fixation rate (p = 0.033). Moreover, the functional recovery was poorer, revealing a significantly lower FAOS in the sport/rec scale (p < 0.001). Subgroup analysis showed that among SER IV ankle fracture patients, FAOS was much lower in pain (p = 0.042) and sport/rec scales (p < 0.001) for those with dislocations. American Orthopedic Foot and Ankle Society ankle hindfoot score revealed no significant difference between dislocation and no-dislocation patients. CONCLUSION Dislocation in SER ankle fractures suggests more severe injury and negatively affects functional recovery, mainly manifested as more pain and poorer motor function, especially in SER IV ankle cases.

Objective:To study the effects of fluoride and aluminum exposure alone and in combination on pyroptosis and the NOD-like receptor protein 3 (NLRP3)/cysteinyl aspartate specific proteinase-1 (Caspase-1)/gasdermin D (GSDMD) signaling pathway in NG108-15 cells.Methods:Using a factorial design method, NG108-15 cells cultured in vitro were divided into control group [0 mg/L sodium fluoride (NaF) + 0 mg/L aluminium trichloride (AlCl 3)], fluoride group (40 mg/L NaF + 0 mg/L AlCl 3), aluminum group (0 mg/L NaF + 160 mg/L AlCl 3), and fluoride + aluminum group (40 mg/L NaF + 160 mg/L AlCl 3) according to the concentrations of NaF and AlCl 3. After 24 hours of cultivation, the cells were collected for subsequent experiments. The fluorescence intensity of pyroptosis index GSDMD in each group was detected by immunofluorescence method. The mRNA expression levels of NLRP3, apoptosis associated speck-like protein (ASC), Caspase-1, and GSDMD in each group were detected by real-time fluorescence quantitative PCR (qRT-PCR). The protein expression levels of NLRP3, ASC, Caspase-1, GSDMD, gasdermin D N-terminus (GSDMD-N) and interleukin-1β (IL-1β) in each group were detected by Western blotting. Results:The immunofluorescence results showed that compared with the control group (1.00 ± 0.02), the fluorescence intensity of GSDMD in the fluoride, aluminum, and fluoride + aluminum groups (1.49 ± 0.02, 1.22 ± 0.04, 1.25 ± 0.03) were higher ( P < 0.05). The results of qRT-PCR showed that compared with the control group (1.00 ± 0.02, 1.00 ± 0.01, 1.00 ± 0.08, 1.00 ± 0.06), the mRNA expression levels of NLRP3 (1.21 ± 0.06, 1.60 ± 0.07, 1.42 ± 0.02), ASC (2.61 ± 0.07, 1.53 ± 0.01, 2.12 ± 0.03), Caspase-1 (1.32 ± 0.05, 1.53 ± 0.04, 2.07 ± 0.05), and GSDMD (1.60 ± 0.03, 1.65 ± 0.04, 2.23 ± 0.05) were higher in the fluoride, aluminum, and fluoride + aluminum groups ( P < 0.05). Western blotting results showed that compared with the control group (1.00 ± 0.04, 1.00 ± 0.08, 1.00 ± 0.05, 1.00 ± 0.02, 1.00 ± 0.03, 1.00 ± 0.06), the protein expression levels of NLRP3 (1.55 ± 0.06, 1.40 ± 0.07, 1.24 ± 0.05), ASC (1.66 ± 0.05, 1.48 ± 0.06, 1.32 ± 0.06), Caspase-1 (1.51 ± 0.02, 1.40 ± 0.01, 1.28 ± 0.03), GSDMD (1.24 ± 0.03, 1.31 ± 0.06, 1.18 ± 0.03), GSDMD-N (1.18 ± 0.04, 1.27 ± 0.03, 1.27 ± 0.03), and IL-1β (1.81 ± 0.03, 1.70 ± 0.08, 1.52 ± 0.05) were higher in the fluoride, aluminum, and fluoride + aluminum groups ( P < 0.05). Conclusion:Exposure to fluoride and aluminum alone and in combination can induce pyroptosis in NG108-15 cells, and the mechanism may be related to up-regulation of molecules related to the NLRP3/Caspase-1/GSDMD signaling pathway.

Objective:To investigate the effects of Japan tallow(JT)on liver injury and gut microbiota regulation in type 2 diabetes mellitus(T2DM)mice,thereby providing a theoretical basis for developing therapeutic edible oils for diabetes treatment.Methods:T2DM animal model was established through a combined approach of nutritional intervention and chemical induction.Experimental animals were first fed a high-fat diet(HFD)for 6 weeks,followed by intraperitoneal injection of freshly prepared streptozotocin(STZ).After successful model establishment,the mice were divided into five groups(n=6 per group):control group without any intervention;T2DM group;HFD reversion to standard chow group;metformin group;and JT intervention group,which received respective treatments for 4 weeks.At the endpoint,fresh fecal samples were collected from all groups,and the gut microbiota composition was analyzed using 16s rDNA high-throughput sequencing.Liver histopathological changes were examined using histological methods.Results:Compared with the normal control(ND),T2DM mice showed significantly increased fasting blood glucose(FBG)levels,with evident hepatocyte lipid accumulation,steatosis,inflammatory cell infiltration,and widespread vacuolar and fatty degeneration.After Japan tallow(JT)intervention,FBG levels decreased significantly,liver color approximated normal appearance,and pathological morphology improved noticeably.16s rDNA sequencing analysis demonstrated that JT treatment could effectively regulate the intestinal microbiota structure in T2DM mice.Increased microbial α-diversity indices(Chao1,observed_species,Faith_pd,Simpson);At the phylum level,increased Verrucomicrobia abundance while decreased Proteobacteria were detected;At the family level,elevated Bifidobacteriaceae and reduced Porphyromonadaceae were seen;At the genus level,Bifidobacterium was promoted and Akkermansia proliferat while Escherichia and Klebsiella were downregulated.Conclusions:Japan tallow exhibits significant effects in alleviating liver tissue damage and regulating intestinal microbiota disorders in T2DM mice,our study indicated new theoretical basis for the research and development of potential strategy for diabetes.

Objective:To analyze the abnormal features of brain structure and functional connection (FC) in adolescent female patients with borderline personality disorder (BPD) and to explore the relationship between brain structure and clinical severity.Method:Eighteen female patients with BPD and 18 healthy controls matched with sex, age and education level aged 12—17 were examined by resting functional magnetic resonance imaging (fMRI). The differences of gray matter volume (GMV) and functional connection between the two groups were compared by voxel-based morphometric measurement and functional connection method, and t-test was used to compare the differences between the two groups. Spearman correlation analysis was used to analyze the correlation between abnormal brain regions, brain regions with different functional connections and Borderline Symptom List (BSL-23) scores. Result:The GMV of the left inferior temporal gyrus ( t=4.23), the right inferior temporal gyrus ( t=4.85), and the left middle orbital frontal gyrus ( t=4.16) were significantly larger in the BPD group than those in the healthy controls (GRF corrected voxel P<0.005, cluster P<0.05 two-tails). FC decreased in left inferior temporal gyrus and right middle temporal gyrus ( t=-6.20), increased in the left inferior temporal gyrus and the right fusiform gyrus ( t=5.75), the left inferior temporal gyrus and the left inferior parietal marginal angular gyrus ( t=4.38;GRF corrected voxel P<0.005, cluster P<0.05, two-tailed). In the BPD group, the increase in orbital frontal gray matter volume was negatively correlated with the emotional items BSL9 (tension; r=-0.523, P=0.023), BSL14 (rapid emotional changes; r=-0.549, P=0.018), BSL15 (tolerated pain; r=-0.589, P=0.010), BSL17 (vulnerable; r=-0.554, P=0.017), BSL5 (self-injury; r=-0.616, P=0.006) and BSL18 (suicide attraction; r=-0.661, P=0.003) in the BSL-23. Conclusion:There are differences in the GMV of the inferior temporal and the left middle orbital frontal lobe in adolescent female patients with BPD. The FC abnormalities of the left inferior temporal and right middle temporal gyrus, the left inferior temporal gyrus and the right fusiform gyrus, the left inferior temporal gyrus and the left inferior parietal marginal angular gyrus, especially the changes of GMV in the orbital frontal brain structure might participate in the pathological mechanism of emotion regulation injury in patients with BPD.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

OBJECTIVE: This study was aimed at investigating the carrier rate of, and molecular variation in, α- and β-globin gene mutations in Hunan Province. METHODS: We recruited 25,946 individuals attending premarital screening from 42 districts and counties in all 14 cities of Hunan Province. Hematological screening was performed, and molecular parameters were assessed. RESULTS: The overall carrier rate of thalassemia was 7.1%, including 4.83% for α-thalassemia, 2.15% for β-thalassemia, and 0.12% for both α- and β-thalassemia. The highest carrier rate of thalassemia was in Yongzhou (14.57%). The most abundant genotype of α-thalassemia and β-thalassemia was -α ^3.7/αα (50.23%) and β ^IVS-II-654/β ^N (28.23%), respectively. Four α-globin mutations [CD108 (ACC>AAC), CAP +29 (G>C), Hb Agrinio and Hb Cervantes] and six β-globin mutations [CAP +8 (C>T), IVS-II-848 (C>T), -56 (G>C), beta nt-77 (G>C), codon 20/21 (-TGGA) and Hb Knossos] had not previously been identified in China. Furthermore, this study provides the first report of the carrier rates of abnormal hemoglobin variants and α-globin triplication in Hunan Province, which were 0.49% and 1.99%, respectively. CONCLUSION Our study demonstrates the high complexity and diversity of thalassemia gene mutations in the Hunan population. The results should facilitate genetic counselling and the prevention of severe thalassemia in this region.
