Objective:To analyze the efficacy, influencing factors, and risk warning of multi-plane low-temperature plasma radiofrequency ablation（MLT-RFA） in the treatment of obstructive sleep apnea hypopnea syndrome（OSAHS）. Methods:A total of 118 OSAHS patients admitted from October 2022 to June 2024 were selected as the research subjects. They were divided into mild group（n=46）, moderate group（n=52）, and severe group（n=20） according to the severity of their condition. MLT-RFA treatment was used for all patients. After surgery, the results of polysomnography（PSG） and the changes in the Calier Sleep Apnea Quality of Life Index（SAQLI） were observed before and after treatment. The incidence of complications after treatment was recorded, and the clinical efficacy of the patients was evaluated. At the same time, they were divided into a treatment effective group（n=106） and an ineffective group（n=12） according to their effects. The general clinical data of the two groups were compared, and binary logistics regression analysis was conducted to identify independent factors that affect treatment efficacy and construct a model. ROC curve analysis was used to evaluate the diagnostic efficacy of the model. Results:The treatment effectiveness rate of the mild group was 93.48%, the moderate group was 90.38%, and the severe group was 80.00%. There was no statistically significant difference in the treatment effectiveness rate among the three groups（P>0.05）. The AHI of the mild group, moderate group, and severe group increased sequentially, while the LSaO2and SAQLI scores decreased sequentially. After treatment, the AHI of all three groups decreased compared to before treatment, while the LSaO2and SAQLI scores increased compared to before treatment, and the differences were statistically significant（P<0.05）. The pre-treatment AHI of the effective group was lower than that of the ineffective group, and the pre-treatment LSaO2and SAQLI were higher than those of the ineffective group, with statistically significant differences（P<0.05）. Pre-treatment LSaO2and pre-treatment SAQLI are independent factors affecting the efficacy of MLT-RFA（P<0.05）. The AUC of pre-treatment LSaO2, pre-treatment SAQLI, and combined prediction were 0.907, 0.763, and 0.947, respectively, with sensitivities of 0.896, 0.840, and 0.917, and specificities of 0.833, 0.667, and 0.887, respectively. Conclusion:MLT-RFA has a significant effect on the treatment of OSAHS, and the AHI, LSaO2, and SAQLI of patients before treatment can predict the treatment effect, with LSaO2 and SAQLI being independent influencing factors. The combinerd prediction model exhibits high diagnostic efficiency, sensitivity, and specificity.

Objective:To explore the risk factors for malnutrition after a traumatic brain injury and to construct a model which usefully predicts that risk.Methods:This was a retrospective study of 374 patients with a craniocerebral injury for whom the relevant clinical data were available. Based on their nutritional status, they were stratified into a malnutrition group ( n=220) and a control group ( n=154). Univariate and multivariate logistic regressions were evaluated seeking to identify the independent risk factors associated with malnutrition, and a prediction model was constructed based on the results. The model′s discrimination ability and accuracy were assessed using a receiver operating characteristics (ROC) curve. Results:A total of 220 patients (58.8%) developed malnutrition. Multifactorial logistic regression analysis showed that the independent risk factors for malnutrition were: age ≥60 years, pulmonary infection, dysphagia, cognitive impairment, a GCS score ≤8, or a Barthel index ≤40. In the ROC curve analysis, the area under the curve quantifying the model′s ability to predict malnutrition was 0.924 (95% CI: 0.896, 0.951), with a sensitivity of 0.868 and a specificity of 0.857, indicating its good prediction performance. Conclusions:Age ≥60 years, pulmonary infection, dysphagia, cognitive impairment, a GCS score ≤8 or a Barthel index ≤40 are independent predictors of malnutrition after a traumatic brain injury. The prediction model constructed based on those risk factors has demonstrated useful predictive power for malnutrition.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To investigate the clinical manifestations, therapeutic strategies and prognostic outcomes in pediatric patients with severe Mycoplasma pneumoniae pneumonia (SMPP) complicated by cardiac thrombosis. Methods:This case series study retrospectively analyzed 15 pediatric patients with SMPP complicated by cardiac thrombosis. The patients was recruited from the Department of Pediatric Respiratory Medicine at Shandong Provincial Hospital Affiliated to Shandong First Medical University between July 2018 and January 2025. Comprehensive clinical data and follow-up information were collected.Results:Among the 15 children, 10 were male and 5 were female, and the age of onset was 8.0 (6.3, 10.0) years. All 15 children presented with fever and cough, while additional symptoms included dyspnea in 7 cases, chest pain in 6 cases, hemoptysis in 3 cases, and chest tightness in 1 case. The white blood cell count was 11.7 (9.5, 15.9)×10 9/L, C-reactive protein was 31.6 (17.5, 64.8) mg/L and lactate dehydrogenase was 548.2 (410.4, 768.3) U/L. A total of 14 children underwent testing for the Mycoplasma pneumoniae drug resistance genes 2063A>G and 2064A>G, of which 13 tested positive. The plasma D-dimer levels of 15 children were 8.77 (7.23, 12.50) mg/L, all of which were higher than normal. Among the 15 children, 5 had decreased activity of anticoagulant proteins (protein C, protein S, antithrombin Ⅲ), and 8 tested positive for antiphospholipid antibodies. Chest CT scans of all 15 children showed pulmonary consolidation and (or) atelectasis, with pleural effusion present in 12 cases. In the 15 children, thrombosis was detected at 14.0 (11.0, 18.0) days after the onset of illness. The locations of cardiac thrombosis included the right ventricle in 9 cases, the right atrium in 5 cases, and the left atrium in 1 case. Additionally, 10 cases had pulmonary vascular embolism, comprising 9 cases of pulmonary artery thrombosis and 1 case of pulmonary vein thrombosis. After anticoagulant treatment, cardiac thrombi disappeared in 10 children. Five children who did not show improvement with anticoagulation underwent surgical thrombectomy. In the follow-up of 15 children, lung imaging basically returned to normal, with no major hemorrhagic events or other adverse events. Conclusions:In children with Mycoplasma pneumoniae pneumonia, the presence of clinical symptoms such as shortness of breath, chest pain and hemoptysis, along with elevated plasma D-dimer levels, should raise suspicion for the possibility of cardiac thrombosis. SMPP complicated by cardiac thrombosis, prognosis is good following anticoagulation or surgical treatment.

In this experiment, self-assembled nanoparticles(SANs) were prepared by the pH-driven method, and Her-HCP SAN was constructed by using herpetrione(Her) and Herpetospermum caudigerum polysaccharides(HCPs). The average particle size and polydispersity index(PDI) were used as evaluation indexes for process optimization, and the quality of the final formulation was evaluated in terms of particle size, PDI, Zeta potential, and microstructure. The proposed Her-HCP SAN showed a spheroid structure and uniform morphology, with an average particle size of(244.58±16.84) nm, a PDI of 0.147 1±0.014 8, and a Zeta potential of(-38.52±2.11) mV. Her-HCP SAN significantly increased the saturation solubility of Her by 2.69 times, with a cumulative release of 90.18% within eight hours. The results of in vivo unidirectional intestinal perfusion reveal that Her active pharmaceutical ingredient(API) is most effectively absorbed in the jejunum, where both K_a and P_(app) are significantly higher compared to the ileum(P<0.001). However, the addition of HCP leads to a significant reduction in the P_(app) of Her in the jejunum(P<0.05). Furthermore, the formation of the Her-HCP SAN results in a notably lower P_(app) in the jejunum compared to Her API alone(P<0.001), while both K_a and P_(app) in the ileum are significantly increased(P<0.001, P<0.05). The absorption of Her-HCP SAN at different concentrations in the ileum shows no significant differences, and the pH has no significant effect on the absorption of Her-HCP SAN in the ileum. The addition of the transporter protein inhibitors(indomethacin and rifampicin) significantly increases the absorption parameters K_a and P_(app) of Her-HCP SAN in the ileum(P<0.05,P<0.01), whereas the addition of verapamil has no significant effect on the intestinal absorption parameters of Her-HCP SAN, suggesting that Her may be a substrate for multidrug resistance-associated protein 2 and breast cancer resistance proteins but not a substrate of P-glycoprotein.

OBJECTIVE: To compare clinical efficacy of transaxillary posterior margin approach and translateral margin approach for the treatment of Miller typeⅡand Ⅳ scapular fractures. METHODS: From June 2020 to June 2024, 28 patients with fresh scapular fractures (Miller typeⅡand Ⅳ) who were treated with open reduction and locked plate internal fixation were retrospectively analyzed and divided into two groups. There were 13 patients in posterior axillary margin group, including 8 males and 5 females, aged from 26 to 71 years old with an average of (39.2±6.5) years old;5 patients with typeⅡand 8 patients with type Ⅳ according to Miller classification;9 patients caused by falling down, 4 patients caused by car accident;7 patients on the right side, 6 patients on the left side;the time from injury to operation ranged from 3 to 5 days with an average of (4.07±0.86) days. There were 15 patients in lateral scapula margin group, including 10 males and 5 females, aged from 27 to 63 years old with an average of (43.6±8.5) years old;7 patients with typeⅡand 8 patients with type Ⅳ according to Miller classification;10 patients caused by falling down, 5 patients caused by car accident;6 patients on the right side, 9 patients on the left side;the time from injury to operation ranged from 3 to 5 days with an average of (4.20±0.67) days. Operative time, intraoperative blood loss, fracture healing time, glenopolar angle (GPA) immediately after operation were compared between two groups. Visual analogue scale (VAS) and Constant-Murley shoulder joint function score were used to evaluate clinical effect at 3 and 6 months after operation, respectively, and the joint motions were evaluated at 6 months after operation. RESULTS: None of patients occurred wound infection, vascular and nerve damage, loosening or rupture of internal fixation. Both groups were followed up for 8 to 12 months with an average of (9.6±1.5) months. Operative time and intraoperative blood loss of posterior axillary margin group were (76.92±5.60) min and (84.86±10.08) ml, respectively, which were better than those of lateral scapula margin group(84.67±6.93) min and(115.00±12.39) ml(P<0.05). Immediate GPA in posterior axillary margin group (36.62±0.87) °and lateral scapula margin group (36.20±0.82)°were significantly improved compared with preoperative (16.10±1.14) °, (16.20±1.20) °(P<0.05), while there was no statistical significance between two groups (P>0.05). There were no significant difference in fracture healing time and postoperative VAS at 3 and 6 months between two groups (P>0.05). Postoperative Constant-Murley score of posterior axillary margin group (75.00±4.02) was higher than that of lateral scapular margin group (70.86±4.24) at 3 months (P<0.05), while there was no significant difference between two groups at 6 months after operation (P>0.05). At 6 months after operation, joint motion of posterior axillary margin group in flexion (160.38±13.61)°, abduction (154.61±13.91)°, rotation (83.08±2.53)°, rotation (62.69±2.59) ° and extension (51.54±3.15) °, respectively, which were higher than that of lateral scapular margin group in (148.00±15.44)°, (144.00±11.05)°, (79.67±3.99)°, (57.33±4.95)°, (47.33±4.16)°(P<0.05). CONCLUSION Compared with lateral margin of scapula intermuscular space approach, Buttress approach through the posterior axillary margin for the treatment of Miller typeⅡand Ⅳ scapular fractures provides extensive intraoperative visual field exposure, stable fracture support and less surgical trauma, which could shorten operative time and reduce intraoperative blood loss, providing a new reference for the treatment of complex scapular fractures.

OBJECTIVE: To explore the effect of nano-hydroxyapatite/collagen composite (nHAC) on bone graft fusion after anterior cervical discectomy and fusion (ACDF) in patients with cervical spondylosis and low bone mass. METHODS: A retrospective analysis was conducted on 47 patients with low bone mass who underwent ACDF from 2017 to 2021. They were divided into the nHAC group and the allogeneic bone group according to different bone graft materials. The nHAC group included 26 cases, with 8 males and 18 females;aged 50 to 78 years old with an average of (62.81±7.79) years old;the CT value of C₂-C₇ vertebrae was (264.16±36.33) HU. The allogeneic bone group included 21 cases, with 9 males and 12 females;aged 54 to 75 years old with an average of (65.95±6.58) years old;the CT value of C₂-C₇ vertebrae was (272.39±40.44) HU. The visual analogue scale (VAS), neck disability index (NDI), and Japanese Orthopaedic Association (JOA) spinal cord function score were compared before surgery, 1 week after surgery, and at the last follow-up to evaluate the clinical efficacy. Imaging assessment included C₂-C₇ Cobb angle, surgical segment height, intervertebral fusion, and whether the cage subsidence occurred at 1 week after surgery and the last follow-up. RESULTS: The follow-up duration ranged from 26 to 39 months with an average of (33.27±3.34) months in the nHAC group and 26 to 41 months with an average of (31.86±3.57) months in the allogeneic bone group. At 1 week after surgery and the last follow-up, the VAS, NDI scores, and JOA scores in both groups were significantly improved compared with those before surgery, with statistically significant differences (P<0.05). At 1 week after surgery, the C₂-C₇ Cobb angles in the nHAC group and the allogeneic bone group were (14.26±10.32)° and (14.28±8.20)° respectively, which were significantly different from those before surgery (P<0.05). At the last follow-up, the C₂-C₇ Cobb angles in both groups were smaller than those at 1 week after surgery, with statistically significant differences (P<0.05). At 1 week after surgery, the height of the surgical segment in the nHAC group was (31.65±2.55) mm, and that in the allogeneic bone group was (33.63±3.26) mm, which were significantly different from those before surgery (P<0.05). At the last follow-up, the height of the surgical segment in both groups decreased compared with that at 1 week after surgery, with statistically significant differences (P<0.05). At the last follow-up, 39 surgical segments were fused and 6 cages subsided in the nHAC group;40 surgical segments were fused and 7 cages subsided in the allogeneic bone group;there was no statistically significant difference between the two groups (P>0.05). Compared with the CT value of vertebrae without cage subsidence, the CT value of vertebrae with cage subsidence in both groups was significantly lower, with a statistically significant difference (P<0.05). CONCLUSION The application of nHAC in ACDF for patients with low bone mass can achieve effective fusion of the surgical segment. There is no significant difference in improving clinical efficacy, intervertebral fusion, and cage subsidence compared with the allogeneic bone group. With the extension of follow-up time, the C₂-C₇ Cobb angle decreases, the height of the surgical segment is lost, and the cage subsides in both the nHAC group and the allogeneic bone group, which may be related to low bone mass. Low bone mass may be one of the risk factors for cervical spine sequence changes, surgical segment height loss, and cage subsidence after ACDF.

Peyronie's disease (PD) is a disorder characterized by fibrous plaque formation in the penile tissue that leads to curvature and complications in advanced stages. In this study, we aimed to compare four injectable induction agents for the establishment of a robust rat model of PD: transforming growth factor-β1 (TGF-β1), fibrin, sodium tetradecyl sulfate (STS) combined with TGF-β1, and polidocanol (POL) combined with TGF-β1. The results showed that injection of TGF-β1 or fibrin into the tunica albuginea induced pathological endpoints without causing penile curvature. The STS + TGF-β1 combination resulted in both histological and morphological alterations, but with a high incidence of localized necrosis that led to animal death. The POL + TGF-β1 combination produced pathological changes and curvature comparable to STS + TGF-β1 and led to fewer complications. In conclusion, fibrin, STS + TGF-β1, and POL + TGF-β1 all induced PD with a certain degree of penile curvature and histological fibrosis in rats. The POL + TGF-β1 combination offered comparatively greater safety and clinical relevance and may have the greatest potential for PD research using model rats.

The circadian clock is an important internal time regulatory system for a range of physiological and behavioral rhythms within living organisms. Testosterone, as one of the most critical sex hormones, is essential for the development of the reproductive system, maintenance of reproductive function, and the overall health of males. The secretion of testosterone in mammals is characterized by distinct circadian rhythms and is closely associated with the regulation of circadian clock genes. Here we review the central and peripheral regulatory mechanisms underlying the influence of circadian clock genes upon testosterone synthesis. We also examined the specific effects of these genes on the occurrence, development, and treatment of common male diseases, including late-onset hypogonadism, erectile dysfunction, male infertility, and prostate cancer.
