Obstructive sleep apnea (OSA) is a global public health concern characterized by repeated upper airway collapse during sleep. Research indicates that OSA is a risk factor for the development of various diseases, including cardiovascular disease, metabolic disorders, respiratory diseases, neurodegenerative diseases, and cancer. Exosomes, extracellular vesicles released by most cell types, play a key role in intercellular communication by transporting their contents-such as microRNA, messenger RNA, DNA, proteins, and lipids-to target cells. Intermittent hypoxia associated with OSA alters circulating exosomes and promotes a range of cellular structural and functional disturbances involved in the pathogenesis of OSA-related diseases. This review discusses the potential roles of exosomes and exosome-derived molecules in the onset and progression of OSA-associated diseases, explores the possible underlying mechanisms, and highlights novel strategies for developing exosome-based therapies for these conditions.

This study established a high performance liquid chromatography(HPLC) fingerprint of Chuanxiong Rhizoma from different producing areas and screened its potential differential components for producing areas by chemometrics. Furthermore, the content of the above differential components in Chuanxiong Rhizoma from different producing areas was measured and compared. Then, the geoherbalism markers(geo-markers) that can be used to distinguish Dao-di and non-Dao-di Chuanxiong Rhizoma were excavated by chemometrics. In fingerprint studies, a total of 27 common peaks were determined, and the fingerprint similarity for 37 batches of Chuanxiong Rhizoma samples from different producing areas was above 0.968. The orthogonal partial least squares-discriminant analysis(OPLS-DA) was capable of distinguishing Chuanxiong Rhizoma from Sichuan and from three other provinces, as well as Dao-di Chuanxiong Rhizoma(from Dujiangyan) and non-Dao-di Chuanxiong Rhizoma(from other producing areas) in Sichuan province. Meanwhile, 14 potential differential components in Chuanxiong Rhizoma from different provinces and 16 potential differential components in Chuanxiong Rhizoma from different producing areas in Sichuan were screened by the variable importance in projection(VIP) analysis under OPLS-DA. The reference standards were used to identify 10 potential differential components in the common peaks, and subsequent content determination verified that the content of the above 10 potential differential components was different among different producing areas. Then, the OPLS-DA and VIP analysis were performed with the content of the 10 potential differential components as variables. The results showed that Z-ligustilide, chlorogenic acid, and the ratio of butylidenephthalide/senkyunolide A were the geo-markers that can distinguish Chuanxiong Rhizoma from Sichuan and Chuanxiong Rhizoma from Shaanxi, Hebei, and Jiangxi, while Z-ligustilide, n-butylphthalide, and the ratios of Z-ligustilide/senkyunolide A and butylidenephthalide/senkyunolide A were the geo-markers that can distinguish Dao-di Chuanxiong Rhizoma(from Dujiangyan) and non-Dao-di Chuanxiong Rhizoma(from other producing areas) in Sichuan province. This study elucidated the differences in material basis of Dao-di and non-Dao-di Chuanxiong Rhizoma based on fingerprinting and content determination combined with chemometrics, which provides a reference for the study of material basis of Dao-di traditional Chinese medicine.

OBJECTIVE: To compare the effectiveness of dynamic fixation and plate augmentation combined with bone grafting for femoral nonunion after interlocking intramedullary nails. METHODS: Between January 2008 and December 2022, a total of 128 patients who developed femoral nonunion following static fixation with interlocking intramedullary nailing were retrospectively analyzed. All patients underwent either dynamic intramedullary nail fixation or plate fixation with bone grafting while retaining the original intramedullary nail. There were 104 males and 24 females;the age ranged from 19 to 59 years old with an average of(32.70±9.21) years old. Patients were categorized into dynamization group and plate group based on the distinct treatment modalities. There were 67 patients in the dynamization group, comprising 54 males and 13 females. The age range was from 19 to 58 years old, with a mean age of (32.68±9.33) years old. All patients underwent open reduction and anterograde interlocking intramedullary nail fixation. Dynamic fixation was implemented between 10 and 28 months postoperatively.The plate group comprised 61 patients, of whom 50 were male and 11 were female. The age distribution ranged from 20 to 59 years old, with a mean age of (32.84±9.07) years old. All patients underwent open reduction and anterograde interlocking intramedullary nailing. Plate reinforcement fixation was performed between 10 and 30 months postoperatively. The incision length, duration of surgery, intraoperative blood loss, hospitalization period, fracture healing status, and incidence of complications were compared between the two groups of patients. RESULTS: All patients were followed up for a minimum duration of 1 year. The mean follow-up period for the dynamization group was(26.12±11.82) months, compared to (26.57±12.48) months for the plate group. No statistically significant difference was observed between the two groups (P>0.05). The incision size (2.73±1.21) cm, operation time (22.73±3.20) min and blood loss (19.06±6.22) ml in the dynamization group were significantly less than those in the plate group(22.53±2.24) cm, (126.40±13.91) min and(237.36±81.56) ml, respectively(P<0.05). All nonunion in the plate group were successfully healed, and the healing time duration ranged from 4 to 7 months with an average of(6.16±0.99) months. In the dynamization group, a total of 42 patients achieved fracture healing, with a healing duration ranging from 4 to 8 months with an average of (6.26±1.23) months. There was significant difference in healing rate between 2 groups (P<0.05), but there was no significant difference in healing time between 2 groups (P>0.05). The average treatment cost was(17 700.18±4 846.27) yuan in the plate group and (334.24±18.16) yuan in the dynamization group, and there was significant difference in costs between 2 groups (P<0.05). CONCLUSION Either dynamic fixation or plate augmentation combined with bone grafting is an effective method, but dynamic fixation is superior to plate augmentation combined with bone grafting for the treatment of femoral hyperplastic nonunion after interlocking intramedullary nails. Dynamic fixation offers several advantages, including simplified procedures, reduced trauma, and cost-effectiveness in medical expenses, making it superior to additional plate fixation combined with bone grafting. However, dynamic fixation is not suitable for the treatment of femoral atrophic nonunion.

BACKGROUND: China is seeing a growing demand for rehabilitation treatments for post-stroke upper limb spastic paresis (PSSP-UL). Although acupuncture is known to be effective for PSSP-UL, there is room to enhance its efficacy. OBJECTIVE: This study explored a semi-personalized acupuncture approach for PSSP-UL that used three-dimensional kinematic analysis (3DKA) results to select additional acupoints, and investigated the feasibility, efficacy and safety of this approach. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This single-blind, single-center, randomized, controlled trial involved 74 participants who experienced a first-ever ischemic or hemorrhagic stroke with spastic upper limb paresis. The participants were then randomly assigned to the intervention group or the control group in a 1:1 ratio. Both groups received conventional treatments and acupuncture treatment 5 days a week for 4 weeks. The main acupoints in both groups were the same, while participants in the intervention group received additional acupoints selected on the basis of 3DKA results. Follow-up assessments were conducted for 8 weeks after the treatment. MAIN OUTCOME MEASURES: The primary outcome was the Fugl-Meyer Assessment for Upper Extremity (FMA-UE) response rate (≥ 6-point change) at week 4. Secondary outcomes included changes in motor function (FMA-UE), Brunnstrom recovery stage (BRS), manual muscle test (MMT), spasticity (Modified Ashworth Scale, MAS), and activities of daily life (Modified Barthel Index, MBI) at week 4 and week 12. RESULTS: Sixty-four participants completed the trial and underwent analyses. Compared with control group, the intervention group exhibited a significantly higher FMA-UE response rate at week 4 (χ² = 5.479, P = 0.019) and greater improvements in FMA-UE at both week 4 and week 12 (both P < 0.001). The intervention group also showed bigger improvements from baseline in the MMT grades for shoulder adduction and elbow flexion at weeks 4 and 12 as well as thumb adduction at week 4 (P = 0.007, P = 0.049, P = 0.019, P = 0.008, P = 0.029, respectively). The intervention group showed a better change in the MBI at both week 4 and week 12 (P = 0.004 and P = 0.010, respectively). Although the intervention group had a higher BRS for the hand at week 12 (P = 0.041), no intergroup differences were observed at week 4 (all P > 0.05). The two groups showed no differences in MAS grades as well as in BRS for the arm at weeks 4 and 12 (all P > 0.05). CONCLUSION: Semi-personalized acupuncture prescription based on 3DKA results significantly improved motor function, muscle strength, and activities of daily living in patients with PSSP-UL.

OBJECTIVE: Humans are exposed to complex mixtures of environmental chemicals and other factors that can affect their health. Analysis of these mixture exposures presents several key challenges for environmental epidemiology and risk assessment, including high dimensionality, correlated exposure, and subtle individual effects. METHODS: We proposed a novel statistical approach, the generalized functional linear model (GFLM), to analyze the health effects of exposure mixtures. GFLM treats the effect of mixture exposures as a smooth function by reordering exposures based on specific mechanisms and capturing internal correlations to provide a meaningful estimation and interpretation. The robustness and efficiency was evaluated under various scenarios through extensive simulation studies. RESULTS: We applied the GFLM to two datasets from the National Health and Nutrition Examination Survey (NHANES). In the first application, we examined the effects of 37 nutrients on BMI (2011-2016 cycles). The GFLM identified a significant mixture effect, with fiber and fat emerging as the nutrients with the greatest negative and positive effects on BMI, respectively. For the second application, we investigated the association between four pre- and perfluoroalkyl substances (PFAS) and gout risk (2007-2018 cycles). Unlike traditional methods, the GFLM indicated no significant association, demonstrating its robustness to multicollinearity. CONCLUSION GFLM framework is a powerful tool for mixture exposure analysis, offering improved handling of correlated exposures and interpretable results. It demonstrates robust performance across various scenarios and real-world applications, advancing our understanding of complex environmental exposures and their health impacts on environmental epidemiology and toxicology.
