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.

Growth arrest DNA damage-inducible protein 45 β (GADD45B) has been reported to be a regulatory factor for active DNA demethylation and is implicated in the modulation of synaptic plasticity and chronic stress-related psychopathological processes. However, its precise role and mechanism of action in stress susceptibility remain elusive. In this study, we found a significant reduction in GADD45B expression specifically in the ventral, but not the dorsal hippocampal CA1 (dCA1) of stress-susceptible mice. Furthermore, we demonstrated that GADD45B negatively regulates susceptibility to social stress and NMDA receptor-dependent long-term potentiation (LTP) in the ventral hippocampal CA1 (vCA1). Importantly, through pharmacological inhibition using the NMDA receptor antagonist MK801, we provided further evidence supporting the hypothesis that GADD45B potentially modulates susceptibility to social stress by influencing NMDA receptor-mediated LTP. Collectively, these results suggested that modulation of NMDA receptor-mediated synaptic plasticity is a pivotal mechanism underlying the regulation of susceptibility to social stress by GADD45B.

The incidence of hypertriglyceridemic acute pancreatitis(HTG-AP)has been gradually rising in recent years.According to published findings,high triglyceride levels are strongly associated with the severity of acute pancreatitis,and may lead to a higher incidence of complications and worse prognosis.However,the risk factors associated with HTG-AP have not been systematically explored.Early identification and effective management of high triglyceride levels and other potential causes thereof are crucial for reducing the recurrence of acute pancreatitis in clinical practice.Herein,we reviewed the predictive factors of HTG-AP from the perspectives of etiology,pathogenesis,and the relevant biomarkers,such as C-reactive protein,Ca2+,PT,and D-dimer.We aim to provide important early warning signals for clinicians,thereby helping develop personalized treatment protocols and building a more accurate risk prediction model.

Objective:To explore the effect of training program based on service-oriented leadership theory on alleviating the degree of job burnout of clinical nurses, and provide reference for improving the situation of job burnout of nurses.Methods:From January to December 2023, 10 head nurses of a Grade A general hospital were selected by random number table method for training, and 5 nurses were selected from the department of each head nurse by random number table method, a total of 50 nurses were selected as research objects. Through the training program based on the service-oriented leadership theory, the selected head nurses were trained on the service-oriented leadership theory, job burnout and burnout mitigation methods and passed the examination. The training period was 2 months. The general data of 50 nurses were collected, and the job burnout of nurses was investigated by using the Maslach Burnout Inventory before and 6 months after the training of head nurses, and the changes of scores of each dimension were compared by paired t-test. Results:The nurses were (30.4±5.5) years old and their working life was (8.1±6.1) years. The total detection rate of job burnout before training was 100% (50/50), the detection rate of moderate to severe emotional exhaustion was 60% (30/50), and the detection rate after training was 36% (18/50). The detection rate of moderate to severe depersonalization was 72% (36/50) and 40% (20/50) after training. The detection rate of moderate to severe lack of job accomplishment was 86% (43/50) and 54% (27/50) after training. After 6 months of head nurses training, the scores of emotional exhaustion and depersonalization of nurses were significantly lower than those before training, while the scores of personal achievement were significantly higher than those before training, with statistical significances ( P<0.05) . Conclusion:The training program based on service-oriented leadership theory can scientifically prevent and alleviate nurses' job burnout after receiving training of administrators, which is helpful to improve the current situation of nurses' job burnout and reduce the degree of nurses' job burnout, and can play a positive role in promoting nurses' physical and mental health.

Objective To construct and validate a clinical prediction model for delayed extubation undergoing non-emergency major surgery based on the random forest algorithm.Methods Clinical data of 7 528 patients undergoing non-emergency major surgery under general anesthesia from January 2018 to De-cember 2022 were retrospectively collected.The patients were divided into two groups according to whether extubation was performed within 2 hours after surgery:non-delayed extubation group(≤2 hours)and de-layed extubation group(＞2 hours).All the patients were randomly divided into a training set and a valida-tion set in a ratio of 7 ∶ 3.The predictive factors for delayed extubation after surgery were screened through LASSO regression and Logistic regression.The random forest model was established and verified by random forest algorithm.Results There were 123 patients(1.6%)experienced delayed extubation after surgery.ASA physical status,department,intraoperative use of flurbiprofen ester,dexmedetomidine,glucocorticoid,hypocalcemia,severe anemia,intraoperative blood transfusion,and airway spasm were identified as inde-pendent predictive factors for delayed extubation.The area under curve(AUC)value of the random forest prediction model in the validation set was0.751(95%CI0.742-0.778),and the sensitivity was98.1%,and the specificity was 41.9%.Conclusion The predictive model of delayed extubation undergoing non-e-mergency major surgery based on random forest algorithm has a good predictive value,which may be helpful to prevent delayed extubation undergoing non-emergency major surgery.

BACKGROUND:As a dominant breed pig in southwest China,the southern Yunnan small-ear pig has been widely used as an experimental animal in the basic research of other disciplines,but there are still no reports on its application in anterior cruciate ligament reconstruction. OBJECTIVE:To establish a large animal model of the southern Yunnan small-ear pig with anterior cruciate ligament with autologous Achilles tendon was established. METHODS:Twenty adult female Yunnan small-ear pigs were equally randomized into two groups.In the autologous Achilles tendon group,the right knee anterior cruciate ligament was reconstructed with autologous Achilles tendon as a graft,while in the sham-operated group,a similar operation was performed on the right knee without any treatment of the anterior cruciate ligament.General conditions of each pig were observed and recorded before and 12 months after surgery.Ligaments and grafts were taken for gross observation and MAS scoring.Hematoxylin-eosin staining was performed to observe morphological characteristics of ligaments.The staining and arrangement of type I and type Ⅲ collagen were evaluated by immunohistochemistry.Transmission electron microscopy was used to observe the type,size,diameter,ratio,and distribution of collagen fibers in ligaments. RESULTS AND CONCLUSION:All animals had normal diet and activity,good wound healing,no obvious inflammatory reaction,no local purulent infection,and no significant changes in mental and urinary conditions compared with those before surgery.The reconstructed cruciate ligament of the knee was intact,with no stiffness and normal range of motion.Both the anterior drawer and Lachman tests were negative.Gross observation of the graft:12 months after surgery,the grafts was in good position,with good integrity,obvious tension,ligament color close to the original anterior cruciate ligament,and complete surface synovial coverage.Most of the intraarticular ligaments in the autologous Achilles tendon group were defined as MAS I type and a few were defined as MAS Ⅱ type.In the sham-operated group,the intraarticular ligament was defined as MAS I type.Hematoxylin-eosin staining indicated that,12 months after surgery,collagen fibers in the autologous Achilles tendon group began to appear bundled,isotropic,and uniformly arranged,with more obvious isotropic corrugations,and the nuclei were mainly linear or spindle-shaped,which were similar to those in normal anterior cruciate ligament tissue of the sham-operated group.Immunohistochemistry results indicated that,12 months after surgery,there was a higher expression of type I collagen and significantly less expression of type Ⅲ collagen in the reconstructed anterior cruciate ligament in the autologous Achilles tendon group.The degree of type I and type Ⅲ staining was similar in the two groups.Under the transmission electron microscope,the diameter,arrangement and density of collagen fibers in the reconstructed anterior cruciate ligament of the autologous Achilles tendon group were similar to those of the original anterior cruciate ligament at 12 months after surgery,indicating that the ligament remodeling process had been basically completed in the autologous Achilles tendon group at 12 months after surgery.Through a comprehensive evaluation of animal general conditions,ligament general view,MAS score,hematoxylin-eosin staining,immunohistochemistry,and transmission electron microscopy observation,we successfully established a large animal model of anterior cruciate ligament reconstruction using autogenous Achilles tendon in southern Yunnan small-ear pigs,with good morphological,histological and ultrastructural results.

Objective:To evaluate whether individualized dialectical treatment decoction taken for≥6 months after radical surgery for stageⅡ-Ⅲ colorectal cancer(CRC)is superior to surgery alone at preventing early(within 2 years)recurrence and metastasis.Methods:Patients with CRC who underwent radical surgery were enrolled consecutively in The First Affiliated Hospital of Henan University of CM and The First Affiliated Hospital of Henan University.The primary outcome was defined as early recurrence and metastasis for patients who underwent≥6 months of traditional Chinese medicine(TCM)treatment versus those who did not after surgery(Non-TCM).Multivariable modified Pois-son regression was used to model the primary outcome,and propensity score matching(PSM)was included in the regression-based sensit-ivity analysis.Results:A total of 103 patients received TCM treatment and 384 did not.In the entire cohort,the multivariable modified Pois-son regression model showed that the adjusted risk for early recurrence and metastasis was lower in the TCM group10.7%(12/103)vs.21.4%(82/384),relative risk(RR):0.448,95%confidence interval[CI]:0.261-0.769).PSM analysis was used at a 1:2 ratio,resulting in 99 pa-tients in the TCM group and 198 patients in the Non-TCM group.The TCM group still showed a lower risk for early recurrence and metastas-is 11.1%(11/99)vs.21.2%(42/198),RR:0.464,95%CI:0.227-0.948.The results of sensitivity analysis were consistent with multivariable ana-lysis.In this prespecified subgroup analysis,the difference in the rate of the primary outcome between the TCM and the Non-TCM groups was greater among males and those with N2 and moderately-highly differentiated tumors.Kaplan-Meier survival analysis showed that the incidence of early-recurrence-and metastasis-free survival was significantly higher in the TCM group than the Non-TCM groups.Conclusions:For patients with stage Ⅱ-Ⅲ colorectal cancer after radical surgery,individualized dialectical treatment with TCM was associated with a lower risk of early recurrence and metastasis.
