Objective To analyze the efficacy, safety, and learning curve of the three-lobe holmium laser enucleation of the prostate(HoLEP)in the treatment of benign prostatic hyperplasia(BPH)in a county-level hospital.Methods A retrospective analysis was conducted on the clinical data of 65 BPH patients who underwent the three-lobe HoLEP performed by a single surgeon at the Department of Urology, Yining County People's Hospital, during Dec.2023 and Jun.2024.The enucleation efficiency was calculated by dividing the weight of the enucleated prostatic tissue by the enucleation time.A case scatter diagram of enucleation efficiency was plotted according to the chronological order of the operations, and the learning curve was analyzed after fitting.Based on the inflection points of the learning curve, the learning process was divided into the initial learning, mastery, and proficiency phases.The basic clinical data, perioperative indicators, postoperative complications, and follow-up indicators were compared among the different learning phases.Results All 65 procedures were successfully completed.Marked by the enucleation efficiency reaching a plateau, cases 1-20 were defined as the initial learning phase, cases 21-40 as the mastery phase, and cases 41 onwards as the proficiency phase.The prostate volume in the proficiency phase was significantly larger than that in the initial learning and mastery phases(both P<0.05).There were no statistically significant differences in other baseline characteristics among the three groups(all P>0.05).The operation time [(105.50±19.12)min vs.(85.25±26.92)min vs.(69.00±23.58)min] and enucleation time [(76.90±14.19)min vs.(63.70±22.24)min vs.(48.80±20.48)min] showed a decreasing trend across the three groups(all P<0.05).The enucleation efficiency in both the mastery and proficiency phases was significantly higher than that in the initial learning phase [(1.16±0.44)g/min vs.(0.85 ±0.25)g/min, P<0.05;(1.36±0.49)g/min vs.(0.85±0.25)g/min, P<0.05].The enucleation efficiency in the proficiency phase was slightly higher than that in the mastery phase, but the difference was not statistically significant(P= 0.389).There was no significant difference in the incidence of perioperative complications among the three groups(all P>0.05).At the 6-month follow-up, the international prostate symptom score(IPSS), post-void residual(PVR), and maximum urinary flow(Qmax)were significantly improved compared to preoperative values in all three groups(all P<0.05);however, no significant differences were observed among the three groups(all P>0.05).Conclusion The three-lobe HoLEP for the treatment of BPH is safe and effective in a county-level hospital setting.Surgeons with some experience in endoscopic surgery can preliminarily master this technique after a learning period of approximately 20 procedures.

Chronic lung allograft dysfunction (CLAD) is a common complication after lung transplantation, which severely impairs the long-term survival of patients. At present, effective therapeutic approaches remain lacking. Dysregulation of the lung microbiome acts as a pathogenic factor for a variety of pulmonary diseases. Accumulating studies have demonstrated that the compositional characteristics of the lung microbiome after lung transplantation are closely associated with CLAD. Therefore, this article reviews the definition of CLAD, characteristics of the lung microbiome, the influence of the lung microbiome on the occurrence and progression of CLAD, the potential mechanisms underlying the lung microbiome in the pathogenesis of CLAD, and microbiome-based intervention strategies for CLAD. It aims to provide novel insights for the prevention and treatment of CLAD following lung transplantation and further improve the prognosis of lung transplant recipients.

Objective:To investigate the value of a multi-parameter MRI nomogram model in evaluating the recurrence risk of hormone receptor (HR)-positive breast cancer.Methods:This study was a retrospective cross-sectional study. A retrospective analysis was conducted on the clinicopathological data (age, menopausal status, axillary lymph node metastasis, etc.) and imaging data of 220 patients with HR-positive breast cancer who underwent breast MRI examination and were pathologically confirmed at the Second Affiliated Hospital of Nantong University from January 2018 to December 2023. All patients underwent preoperative MRI examinations. Their MRI features were analyzed, and the maximum diameter of the lesion and the apparent diffusion coefficient (ADC) value were measured. Finally, the clinical treatment score (CTS5 score) after 5 years was calculated, and all patients were divided into a low recurrence risk (CTS5 score 3.13 points) and a medium to high recurrence risk (CTS5 score≥3.13 points) group. The patients were followed up through the electronic medical record system or by phone until December 31, 2024 to determine recurrence status. The patients were divided into the recurrence group and the non-recurrence group. The differences in clinicopathological data, MRI features and CTS5 scores between the recurrence group and the non-recurrence group were compared using independent sample t-tests, Mann-Whitney U tests or χ2 tests. Indicators with P0.05 in the univariate analysis were included in the multivariate logistic regression to screen the independent risk factors for predicting the recurrence of HR receptor-positive breast cancer, and a nomogram was constructed to establish the nomogram model. The receiver operating characteristic curves and the area under the curve (AUC) were used to evaluate the efficacy of the nomogram model in predicting the postoperative recurrence risk of patients with HR-positive breast cancer. The variance inflation factor (VIF) was used to evaluate the multicollinearity among independent variables. Calibration curves and decision curve analysis (DCA) were used to assess the fit and net clinical benefit of the nomogram model. Results:Among 220 patients with HR-positive breast cancer, 196 cases were in the non-recurrence group and 24 cases were in the recurrence group. There were statistically significant differences in the maximum diameter of the lesion, axillary lymph node metastasis, ADC value, CTS5 grouping, and CTS5 score between the recurrence group and the non-recurrence group ( P0.05). Multivariate logistic regression analysis showed that the maximum diameter of the lesion ( OR=1.110, 95% CI 1.169-1.503, P0.001), ADC value ( OR=0.993, 95% CI 0.993?0.989, P0.001), and axillary lymph node metastasis ( OR=8.842; 95% CI 2.120?36.884, P=0.003) were independent factors influencing postoperative recurrence in patients with HR-positive breast cancer, and a nomogram model was constructed based on this. VIF analysis showed that no significant multicollinearity was detected among the variables (VIF5). The AUC value of the nomogram model for predicting postoperative recurrence in patients with HR-positive breast cancer was 0.868 (95% CI 0.794-0.942), the sensitivity was 0.875, and the specificity was 0.781. The calibration curve showed that the prediction curve of this model for predicting postoperative recurrence in HR-positive breast cancer patients was basically consistent with the ideal curve trend. DCA showed that this model had a relatively high clinical benefit within the threshold probability range of 0.01% to 90.00%. Conclusion:The nomogram constructed based on multi-parameter MRI features can predict the postoperative recurrence risk of HR-positive breast cancer patients, with good consistency and predictive ability.

Objective:To compare the efficacy of active warming versus conventional warming during the perioperative period of robotic-assisted total hip arthroplasty (THA) for femoral neck fracture in elderly patients.Methods:A retrospective cohort study was conducted to analyze the clinical data of 312 elderly patients with femoral neck fracture who underwent robot-assisted THA at Second Affiliated Hospital of Xi ′an Jiaotong University from January 2024 to January 2025, including 196 males and 116 females, aged 65-89 years [(77.0±7.3)years]. Among them, 156 patients received standardized thermal management (active warming group), involving the administration of pre-warmed intravenous fluids and use of an inflatable warming blanket preoperatively, combined application of a forced-air warming system and warmed fluids intraoperatively, and transfer to a temperature-controlled ward combined with a foot circulatory compression device postoperatively. The other 156 patients received conventional warming with cotton quilts (conventional warming group), involving no administration of pre-warmed intravenous fluids preoperatively, use of warmed fluids intraoperatively, and transfer to a standard ward without the use of a foot circulatory compression device postoperatively. Core body temperature was compared between the two groups at 30 minutes preoperatively, 30 minutes intraoperatively, immediately postoperatively, and at 1 hour, 1 day, 5 days, and 7 days postoperatively. Changes in the coagulation function, including prothrombin time (PT), thrombin time (TT), activated partial thromboplastin time (APTT), and the inflammatory marker C-reactive protein (CRP) were assessed at 1 day preoperatively and at 1, 5, and 7 days postoperatively. Length of hospital stay and incidence of postoperative complications (incision infection, deep vein thrombosis, cardiac complications, and unplanned reoperations) were also recorded. Results:The core body temperature at 30 minutes intraoperatively, immediately postoperatively and at 1 hour postoperatively was (36.77±0.17)℃, (36.29±0.14)℃, and (36.35±0.14)℃ in the active warming group, significantly higher than (36.12±0.27)℃, (35.49±0.25)℃, and (35.67±0.29)℃ in the conventional warming group ( P<0.01). No significant differences in body temperature were observed between the two groups at 30 minutes preoperatively, at 1, 5, or 7 days postoperatively ( P>0.05). At 1 day postoperatively, the PT, TT and APTT were (8.5±1.3)seconds, (10.0±0.9)seconds and (24.8±2.3)seconds, significantly lower than (9.7±1.3)seconds, (12.1±1.5)seconds and (29.2±2.7)seconds in the conventional warming group ( P<0.01). There were no significant differences in PT, TT, APTT or CRP levels between the two groups at 1 day preoperatively or at 5 and 7 days postoperatively ( P>0.05). The CRP level at 1 day postoperatively was (8.0±3.0)mg/L in the active warming group, significantly lower than (13.5±3.2)mg/L in the conventional warming group ( P<0.05). There were no significant differences in CRP between the two groups at 1 day preoperatively or at 5 and 7 days postoperatively ( P>0.05). The average length of hospital stay was (12.2±1.4)days in the active warming group, significantly shorter than (14.9±1.4)days in the conventional warming group ( P<0.01). The perioperative complication rate was 6.4% (10/156) in the active warming group, significantly lower than 17.9% (28/156) in the conventional warming group ( P<0.01). Conclusion:For elderly patients with femoral neck fracture operated via robot-assisted THA, active warming during the perioperative period can more effectively maintain intraoperative normothermia, improve early postoperative coagulation function, reduce inflammatory response, shorten the length of hospital stay, and decrease complication rate when compared with conventional warming.

The " liver disease affecting to the spleen" theory first appeared in Nanjing and was further elaborated in Jingui Yaolue. This theory encapsulates the traditional Chinese medicine principles of the " unity of the five viscera" and the " preventive treatment of disease" . The theory emphasizes that the spleen is the pivotal point where depression may progress from a functional disorder to an organic disease. The liver governs the emotions and qi flow, whereas the spleen is responsible for qi, blood, and body. In the early stages of the disease, emotional disorders and qi flow disorders primarily affect the liver, manifesting as depression or low mood. As the condition progresses, the liver (Wood) overacts on the spleen (Earth), disrupting liver and spleen functions and causing qi and blood disharmony. This stage is marked by fatigue and psychomotor retardation. Prolonged illness depletes qi and blood, eventually involving all five viscera, disrupting the harmony of the five spirits, and affecting both body and spirit. At this advanced phase, intense emotional distress or agitation often arises, accompanied by a heightened risk of suicide. The disease progression follows a dynamic " qi-blood-spirit" pattern, in which depression begins in the liver, characterized by qi stagnation, then affects the spleen, involving blood disharmony. In later stages, the disease eventually affects all viscera, with profound effects on both physical and mental health. Treatment strategies should align with the disease stage. Early intervention should focus on regulating the flow of qi, treating the liver, and strengthening the spleen. In the middle stages, qi and blood should be harmonized while promoting the harmonized functions of the liver and spleen. In the later stages, treatment should harmonize the five viscera to restore balance between body and spirit. Guided by this theory, integrating modern medical understanding of the progression of depression from emotional to somatic symptoms and adopting a stage-based approach to treatment in clinical practice can yield effective therapeutic outcomes for managing depression and related disorders.

Aromatherapy refers to the method of using the aromatic components of plants in appropriate forms to act on the entire body or a specific area to prevent and treat diseases. Essential oils used in aromatherapy are hydrophobic liquids containing volatile aromatic molecules, such as limonene, linalool, linalool acetate, geraniol, and citronellol. These chemicals have been extensively studied and shown to have a variety of functions, including reducing anxiety, relieving depression, promoting sleep, and providing pain relief. Terpenoids are a class of organic molecules with relatively low lipid solubility. After being inhaled, they can pass through the nasal mucosa for transfer or penetrate the skin and enter the bloodstream upon local application. Some of these substances also have the ability to cross the blood-brain barrier, thereby exerting effects on the central nervous system. Currently, the academic community generally agrees that products such as essential oils and aromatherapy from aromatic plants have certain health benefits. However, the process of extracting a single component from it and successfully developing it into a drug still faces many challenges. Its safety and efficacy still need to be further verified through more rigorous and systematic experiments. This article systematically elaborated on the efficacy of aromatic substances, including plant extracts and natural small molecule compounds, in antibacterial and antiviral fields and the regulation of nervous system activity. As a result, a deeper understanding of aromatherapy was achieved. At the same time, the potential of these aromatic substances for drug development was thoroughly explored, providing important references and insights for possible future drug research and application.

Objective:To investigate the value of a multi-parameter MRI nomogram model in evaluating the recurrence risk of hormone receptor (HR)-positive breast cancer.Methods:This study was a retrospective cross-sectional study. A retrospective analysis was conducted on the clinicopathological data (age, menopausal status, axillary lymph node metastasis, etc.) and imaging data of 220 patients with HR-positive breast cancer who underwent breast MRI examination and were pathologically confirmed at the Second Affiliated Hospital of Nantong University from January 2018 to December 2023. All patients underwent preoperative MRI examinations. Their MRI features were analyzed, and the maximum diameter of the lesion and the apparent diffusion coefficient (ADC) value were measured. Finally, the clinical treatment score (CTS5 score) after 5 years was calculated, and all patients were divided into a low recurrence risk (CTS5 score 3.13 points) and a medium to high recurrence risk (CTS5 score≥3.13 points) group. The patients were followed up through the electronic medical record system or by phone until December 31, 2024 to determine recurrence status. The patients were divided into the recurrence group and the non-recurrence group. The differences in clinicopathological data, MRI features and CTS5 scores between the recurrence group and the non-recurrence group were compared using independent sample t-tests, Mann-Whitney U tests or χ2 tests. Indicators with P0.05 in the univariate analysis were included in the multivariate logistic regression to screen the independent risk factors for predicting the recurrence of HR receptor-positive breast cancer, and a nomogram was constructed to establish the nomogram model. The receiver operating characteristic curves and the area under the curve (AUC) were used to evaluate the efficacy of the nomogram model in predicting the postoperative recurrence risk of patients with HR-positive breast cancer. The variance inflation factor (VIF) was used to evaluate the multicollinearity among independent variables. Calibration curves and decision curve analysis (DCA) were used to assess the fit and net clinical benefit of the nomogram model. Results:Among 220 patients with HR-positive breast cancer, 196 cases were in the non-recurrence group and 24 cases were in the recurrence group. There were statistically significant differences in the maximum diameter of the lesion, axillary lymph node metastasis, ADC value, CTS5 grouping, and CTS5 score between the recurrence group and the non-recurrence group ( P0.05). Multivariate logistic regression analysis showed that the maximum diameter of the lesion ( OR=1.110, 95% CI 1.169-1.503, P0.001), ADC value ( OR=0.993, 95% CI 0.993?0.989, P0.001), and axillary lymph node metastasis ( OR=8.842; 95% CI 2.120?36.884, P=0.003) were independent factors influencing postoperative recurrence in patients with HR-positive breast cancer, and a nomogram model was constructed based on this. VIF analysis showed that no significant multicollinearity was detected among the variables (VIF5). The AUC value of the nomogram model for predicting postoperative recurrence in patients with HR-positive breast cancer was 0.868 (95% CI 0.794-0.942), the sensitivity was 0.875, and the specificity was 0.781. The calibration curve showed that the prediction curve of this model for predicting postoperative recurrence in HR-positive breast cancer patients was basically consistent with the ideal curve trend. DCA showed that this model had a relatively high clinical benefit within the threshold probability range of 0.01% to 90.00%. Conclusion:The nomogram constructed based on multi-parameter MRI features can predict the postoperative recurrence risk of HR-positive breast cancer patients, with good consistency and predictive ability.
