Objectives@#. A primary reason for the low adoption of hearing aids (HAs) among the large population with sensorineural hearing loss is the perception that these devices may negatively impact remaining hearing ability. Research addressing this issue has yielded conflicting results. This study examined the long-term effects of HAs on standard audiometric changes in individuals with sensorineural hearing loss. @*Methods@#. We retrospectively analyzed patients who acquired unilateral HAs between 2015 and 2017 and demonstrated consistent use over a 5-year period. We examined demographics, medical comorbidities, audiometric data, and questionnaire results from the Hearing Handicap Inventory for the Elderly and the International Outcome Inventory for Hearing Aids. Additionally, we reviewed each patient’s history of noise exposure and prior HA use. @*Results@#. The study included 55 patients who used unilateral HAs, with a mean follow-up period of 5.32 years. Among them, 31 patients (56.4%) used the HA on the right side. Audiometric data from the aided side showed no significant difference from the unaided side in either the pre-fit pure-tone average of air conduction (AC) or word recognition score (WRS) (P

Background@#The importance of digital technology is increasing among older adults. In this study, the digital health technology utilization status, purpose, and satisfaction of older adults were investigated according to frailty. @*Methods@#A face-to-face survey was conducted among adults aged 65 years or older. Frailty was defined using the Korean version of the fatigue, resistance, ambulation, illnesses, and loss of weight scale. @*Results@#A total of 505 participants completed the survey, with 153 (30.3%) identified as pre-frail or frail and 352 (69.7%) as healthy. All respondents used smartphones; 440 (87.1%) were application users, and 290 (57.4%) were healthcare application users. Wearable devices were used by only 36 patients (7.1%). Pre-frail or frail respondents used social media more frequently than healthy respondents (19.4% vs. 7.4%, P < 0.001). Among the respondents, 319 (63.2%) were not able to install or delete the application themselves, and 277 (54.9%) stated that the application was recommended by their children (or partner). Pre-frail and frail respondents used more healthcare applications to obtain health information (P = 0.002) and were less satisfied with wearable devices (P = 0.02). @*Conclusion@#The usage rate of digital devices, including mobile phones among older adults in Korea is high, whereas that of wearable devices is low. There was a notable difference in the services used by pre-frail and frail respondents compared to healthy respondents. Therefore, when developing digital devices for pre-frail and frail older adults, it is crucial to incorporate customized services that meet their unique needs, particularly those services that they frequently use.

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting both upper and lower motor neurons (MNs) with large unmet medical needs. Multiple pathological mechanisms are considered to contribute to the progression of ALS, including neuronal oxidative stress and mitochondrial dysfunction. Honokiol (HNK) has been reported to exert therapeutic effects in several neurologic disease models including ischemia stroke, Alzheimer's disease and Parkinson's disease. Here we found that honokiol also exhibited protective effects in ALS disease models both in vitro and in vivo. Honokiol improved the viability of NSC-34 motor neuron-like cells that expressed the mutant G93A SOD1 proteins (SOD1-G93A cells for short). Mechanistical studies revealed that honokiol alleviated cellular oxidative stress by enhancing glutathione (GSH) synthesis and activating the nuclear factor erythroid 2-related factor 2 (NRF2)-antioxidant response element (ARE) pathway. Also, honokiol improved both mitochondrial function and morphology via fine-tuning mitochondrial dynamics in SOD1-G93A cells. Importantly, honokiol extended the lifespan of the SOD1-G93A transgenic mice and improved the motor function. The improvement of antioxidant capacity and mitochondrial function was further confirmed in the spinal cord and gastrocnemius muscle in mice. Overall, honokiol showed promising preclinical potential as a multiple target drug for ALS treatment.

OBJECTIVE@#To investigate the effect of acetylcorynoline (Ace) for promoting functional recovery of injured spinal cord in rats and explore the underlying mechanism.@*METHODS@#Rat models of spinal cord injury (SCI) were treated with intraperitoneal injection of different concentrations of Ace, with the sham-operated rats as the control group. After the treatment, the changes in motor function of the rats and the area of spinal cord injury were assessed with BBB score and HE staining, and the changes in pro-inflammatory cytokine levels and microglial activation were determined using PCR, ELISA and immunofluorescence staining. In a lipopolysaccharide (LPS)-treated BV2 cell model, the effects of different concentrations of Ace or DMSO on microglial activation and inflammatory cytokine production were observed. Network pharmacology analysis was performed to predict the target protein and signaling mechanism that mediated the inhibitory effect of Ace on microglia activation, and AutoDock software was used for molecular docking between Ace and the target protein. A signaling pathway blocker (Osimertinib) was used to verify the signaling mechanism in rat models of SCI and LPS-treated BV2 cell model.@*RESULTS@#In rat models of SCI, Ace treatment significantly increased the BBB score, reduced the area of spinal cord injury, and lowered the number of activated microglia cells and the levels of pro-inflammatory cytokines (P < 0.05). The cell experiments showed that Ace treatment significantly lower the level of cell activation and the production of inflammatory cytokines in LPS-treated BV2 cells (P < 0.05). Network pharmacology analysis suggested that EGFR was the main target of Ace, and they bound to each other via hydrogen bonds as shown by molecular docking. Western blotting confirmed that Ace inhibited the activation of the EGFR/MAPK signaling pathway in injured mouse spinal cord tissue and in LPS-treated BV2 cells, and its inhibitory effect was comparable to that of Osimertinib.@*CONCLUSION@#In rat models of SCI, treatment with Ace can inhibit microglia-mediated inflammatory response by regulating the EGFR/MAPK pathway, thus promoting tissue repair and motor function recovery.

Objective:To evaluate the value of shear wave elastography (SWE) in skin assessment of Systemic sclerosis (SSc).Methods:A total of 58 SSc patients admitted to Peking University Third Hospital from May 2021 to October 2022 and 41 healthy volunteers were included in the study. Skin shear wave elastography (SWE) was performed at 17 sites defined in modified Rodnan skin score (mRSS) measurement, and shear wave velocity values were recorded to evaluate skin hardness. SPSS 22.0 software was used to analyze the skin hardness of SSc patients and healthy controls, and the correlation between skin hardness of SSc patients and clinical data was analyzed. A logistic regression model was constructed to evaluate the diagnostic efficacy of skin hardness at different sites of SSc patients, and to further select the most practical measurement site.Results:The SWE value of SSc patients was significantly higher than that of healthy control group ( P<0.05). There was a positive correlation between SWE and mRSS in the measurement of bilateral fingers, bilateral dorsal hands, bilateral forearms, fore-chest, abdomen, bilateral thighs, and bilateral dorsal feet. Skin stiffness measured by SWE was significantly correlated with SSc disease activity score (EScSG-DAI), ( r=0.71, P<0.001), disease injury score (SCTC-DI), (P=0.55, P=0.005) and functional score (HAQ-DI), ( r=0.46, P=0.003). Reducing the number of measurement sites to 12 (bilateral fingers, bilateral hands, bilateral forearms, bilateral upper arms, forehead, fore-chest, bilateral dorsum of feet) performs as well as all 17 measurement sites simultaneously in assessing disease activity. Conclusion:SWE is a good evaluation tool to reflect the skin lesions of SSc, which is of great value for the diagnosis and evaluation of the disease. We can further standardize the measurement sites and select the most appropriate evaluation strategy, so as to achieve better clinical application.

Objective:Exploring the clinical efficacy of using ultra-thin lobulated anterolateral thigh perforator flap(ALTPF) with retrograde separation of perforating vessels from the superficial and deep junction layer of the superficial fascia to repair large soft tissue defects in the foot.Methods:From August 2021 to November 2022, 8 patients (5 males and 3 females) were admitted to the Second Department of Hand and Foot Surgery, the Affiliated Central Hospital of Dalian University of Technology. The patients were 28 to 52 years old in age. The soft tissue defects were located in dorsal and plantar foot. At the plantar foot, the wound involved the weight-bearing area with explosion of bone, tendon or internal fixtures. The area of soft tissue defects was 6.0 cm × 5.0 cm - 16.0 cm × 8.0 cm, and the sizes of ALTPF were 8.0 cm ×5.5 cm - 18.0 cm × 8.5 cm. Preoperative high frequency CUD combined with CTA angiography were employed to locate the 2 flap perforator vessels. By keeping the perforator vessels at center and according to the soft tissue defect area and the wound shape, an ALTPF with a proper size and shape was designed in anterolateral thigh. The perforator were separated in the boundary layer between superficial and deep fascia, where it helped to obviously thin the flap. After the flap was harvested, it was further lobulated between the 2 perforators into 2 lobes after having confirmed the effective blood supply. Finally the lobulated ALTPF was transferred to covered the defect in foot. Cautions should be taken to ensure that the flap covered the weight-bearing area of foot. All the donor sites were directly sutured. Postoperative follow-up was conducted to observe the survival of flaps and the functional recovery of the reconstructed site, also to evaluate the clinical effect. Postoperative follow-up included outpatient visits and reviews over WeChat or telephone. Recovery of the ankle motor function was evaluated according to the American Orthopedic Foot and Ankle Societ (AOFAS) ankle-hind foot score scale.Results:All 8 ALTPF survived. Over 6 to 18 months (10.8 months in average) of follow-up, the transferred flaps had good blood supply, soft in texture, with good elasticity and thin in appearance. Appearance and function of donor sites recovered well, except 1 patient who had mild scar hyperplasia. The plantar flap had good abrasion resistance. No flap damage, bleeding or granulation tissue hyperplasia occurred when walking. The mean score of AOFAS ankle-hind foot score achieved 95.6.Conclusion:The application of ultra-thin lobulated ALTPF with retrograde separation of perforating vessels from the superficial fascia at the junction layer for repairing large soft tissue defects in the foot has good clinical efficacy.

This study aims to systematically review the efficacy and safety of different traditional Chinese medicine injections combined with conventional treatment for patients with post-acute myocardial infarction heart failure. The relevant randomized controlled trial(RCT) was retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library with the time interval from inception to May 13, 2023. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Network Meta-analysis was then performed in RevMan 5.3 and Stata 15.1. A total of 68 RCTs involving 11 traditional Chinese medicine injections and 5 995 patients were included. The results were explained based on the surface under the cumulative ranking curve(SUCRA).(1) In terms of reducing major adverse cardiovascular event(MACE), the therapies followed the trend of Xinmailong Injection+conventional treatment(83.8%) > Yiqi Fumai Injection+conventional treatment(57.1%) > Xuebijing Injection+conventional treatment(56.6%) > Shenmai Injection+conventional treatment(53.1%) > Shenfu Injection+conventional treatment(45.3%) > conventional treatment(4.0%).(2) In terms of increasing left ventricular ejection fraction(LVEF), the therapies followed the trend of Yiqi Fumai Injection+conventional treatment(84.0%) > Shenmai Injection+conventional treatment(69.6%) > Shenfu Injection+conventional treatment(62.7%) > Xinmailong Injection+conventional treatment(61.6%) > Shuxuening Injection+conventional treatment(54.8%) > Shenqi Fuzheng Injection+conventional treatment(46.7%) > Shengmai Injection+conventional treatment(45.9%) > Breviscapine Injection+conventional treatment(39.9%) > Danhong Injection+conventional treatment(38.8%) > Huangqi Injection+conventional treatment(38.7%) > conventional treatment(7.3%).(3) In terms of reducing B-type natriuretic peptide(BNP), the therapies followed the trend of Xinmailong Injection+conventional treatment(98.6%) > Shenmai Injection+conventional treatment(57.7%) > Shenfu Injection+conventional treatment(52.5%) > Shengmai Injection+conventional treatment(30.1%) > conventional treatment(11.0%).(4) In terms of reducing cardiac troponin Ⅰ(cTnⅠ), the therapies followed the trend of Shenmai Injection+conventional treatment(92.3%) > Yiqi Fumai Injection+conventional treatment(61.5%) > Shenfu Injection+conventional treatment(51.2%) > Shengmai Injection+conventional treatment(48.1%) > Xinmailong Injection+conventional treatment(26.6%) > conventional treatment(20.3%).(5) In terms of reducing high-sensitivity C-reactive protein(hs-CRP), the therapies followed the trend of Shenmai Injection+conventional treatment(79.9%) > Xinmailong Injection+conventional treatment(68.1%) > Shenfu Injection+conventional treatment(63.1%) > Xuebijing Injection+conventional treatment(56.7%) > Shengmai Injection+conventional treatment(51.1%) > Shenqi Fuzheng Injection+conventional treatment(42.8%) > Huangqi Injection+conventional treatment(34.7%) > conventional treatment(3.5%).(6) A total of 22 RCTs reported the occurrence of adverse reactions, mainly involving the damage of the circulatory system, digestive system, and coagulation function. The current evidence suggested that Xinmailong Injection+conventional treatment may have the best therapeutic effect in reducing MACE and BNP; Yiqi Fumai Injection+conventional treatment may be the best in increasing LVEF; Shenmai Injection+conventional treatment may be the best in reducing cTnI and hs-CRP. The safety needs further quantitative research and analysis. However, more high-quality RCT is required to validate the above conclusions due to limitations in the quality and quantity of the included studies.

Among them, 23 patients underwent orthopedic robot-assisted resection (robot-assisted surgery group), and 25 patients received traditional open surgery (traditional surgery group). There was no significant difference ( P>0.05) in gender, age, disease duration, lesion location and size, and preoperative visual analogue scale (VAS) score, and musculoskeletal tumor society (MSTS) score between the two groups. The surgical time, intraoperative blood loss, intraoperative lesion localization time, initial localization success rate, infection, and recurrence were recorded and compared. VAS scores before surgery and at 24 hours, 1, 3, 6, and 9 months after surgery and MSTS score before surgery and at 3 months after surgery were assessed.@*RESULTS@#All patients completed the surgery successfully, with no significant difference in surgical time between the two groups ( P>0.05). Compared to the traditional surgery group, the robot-assisted surgery group had less intraoperative blood loss, shorter lesion localization time, and shorter hospitalization time, with significant differences ( P<0.05). The initial localization success rate was higher in the robot-assisted surgery group than in the traditional surgery group, but the difference between the two groups was not significant ( P>0.05). All patients in both groups were followed up, with the follow-up time of 3-12 months in the robot-assisted surgery group (median, 6 months) and 3-14 months in the traditional surgery group (median, 6 months). The postoperative MSTS scores of both groups improved significantly when compared to those before surgery ( P<0.05), but there was no significant difference in the changes in MSTS scores between the two groups ( P>0.05). The postoperative VAS scores of both groups showed a gradually decreasing trend over time ( P<0.05), but there was no significant difference between the two groups after surgery ( P>0.05). During follow-up, except for 1 case of postoperative infection in the traditional surgery group, there was no infections or recurrences in other cases. There was no significant difference in the incidence of postoperative infection between the two groups ( P>0.05).@*CONCLUSION@#Orthopedic robot-assisted osteoid osteoma resection achieves similar short-term effectiveness when compared to traditional open surgery, with shorter lesion localization time.

Objective:To investigate the serum levels of soluble low-density lipoprotein receptor 11 (sLR11), endothelial cell-specific molecule-1 (ESM-1), and advanced glycosylation end products (AGE) in patients with preeclampsia (PE) and their ability to predict adverse pregnancy outcomes.Methods:A total of 141 PE patients (PE group) and 60 normal pregnant women (control group) who were admitted to the Zhangjiakou Maternal and Child Health Hospital from January 2020 to October 2022 were selected. Serum levels of sLR11, ESM-1, and AGE were detected in each group. PE patients were divided into mild preeclampsia (MP, n=78) and severe preeclampsia (SP, n=63) according to the severity of the disease. PE patients were also divided into an adverse pregnancy outcome group ( n=57) and a good pregnancy outcome group ( n=84) based on the occurrence of adverse pregnancy outcomes. Receiver operating characteristic (ROC) curve analysis was used to evaluate the ability of serum levels of sLR11, ESM-1, and AGE to predict adverse pregnancy outcomes in PE patients. Pearson correlation analysis was used to examine the correlation between serum levels of sLR11, ESM-1, and AGE in PE patients. Results:Serum levels of sLR11, ESM-1, and AGE were significantly higher in the PE group than in the control group (all P<0.001). Serum levels of sLR11, ESM-1, and AGE were significantly higher in the SP group than in the MP group (all P<0.001). Serum levels of sLR11, ESM-1, and AGE were significantly higher in the adverse pregnancy outcome group than in the good pregnancy outcome group (all P<0.001). ROC curve analysis showed that the combination of sLR11≥11.65 μg/L, ESM-1≥2.14 μg/L, and AGE≥57.38 ng/ml had the largest area under the curve (AUC) for predicting adverse pregnancy outcomes in PE patients (0.947, 95% CI: 0.890-0.995), with a sensitivity of 97.3% and specificity of 82.0%. Pearson correlation analysis showed that serum levels of sLR11, ESM-1, and AGE were positively correlated in PE patients (all P<0.001). Conclusions:Serum levels of sLR11, ESM-1, and AGE are significantly increased in PE patients and are closely related to disease severity. The combination of these three factors has good value in predicting adverse pregnancy outcomes in PE patients.
