Single-incision laparoscopic cholecystectomy (SILC) represents a significant evolution in minimally invasive surgery, designed to accomplish cholecystectomy via a single umbilical incision. This approach seeks to reduce abdominal wall trauma while optimizing cosmetic outcomes. SILC is a safe and feasible minimally invasive technique for cholecystectomy under defined conditions; however, its broader adoption will require further evidence-based research and the establishment of standardized protocols to support its widespread implementation. When performed by skilled surgeons in carefully selected patients, SILC demonstrates clinical outcomes comparable to those of conventional multiport laparoscopic cholecystectomy, with notable improvements in incision aesthetics. Nonetheless, the technique is limited by a constrained operative field and a protracted learning curve. In response, continuous advancements in instrumentation and procedural modifications have propelled the further development and clinical integration of SILC. Drawing on current literature and clinical experience, this review delineates the technical characteristics, current clinical applications, primary benefits, and prevailing challenges associated with SILC.

Objective To assess the clinical value of a novel surgical technique—Tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device in the resection of anterior mediastinal masses. Methods Patients who underwent tubeless subxiphoid uniportal video-assisted thoracoscopic surgery via balance-shaped sternal elevation device in anterior mediastinal masses process at the Department of Thoracic Surgery, West China Hospital, Sichuan University from March to April 2025 were included, and their clinical data were analyzed. Results A total of 4 patients were included, with 2 males and 2 females, aged 58-75 years. The diameter of the tumor was 2.5-3.0 cm. The operation time was 60.0-150.0 min, intraoperative blood loss was 5-10 mL, pain score on the 3rd day after surgery was 0 points, and postoperative hospital stay was 2-3 days. All patients achieved complete resection of the masses and thymus without perioperative complications. Conclusion The tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device technique optimizes surgical visualization and instrument maneuverability while avoiding complications related to conventional anesthesia and tubing, thereby markedly enhancing the minimally invasive profile of anterior mediastinal masses resections. In addition to maintaining procedural safety, this approach effectively reduces postoperative pain and accelerates patient recovery, highlighting its potential for widespread clinical adoption.

Objective:To explore the value of bedside lung ultrasound in the early diagnosis and severity assessment of ventilator-associated pneumonia (VAP).Methods:A prospective observational study was conducted in 60 patients with VAP (VAP group) and 62 patients without VAP (control group) who were admitted to department of intensive care unit of General Hospital of Ningxia Medical University from September 2018 to July 2020. The gender, age and underlying diseases of non-VAP group were matched with VAP group. The general clinical data such as gender, age, underlying diseases, department source of the patient, acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, sequential organ failure assessment (SOFA) score were recorded. The body temperature, white blood cell count (WBC), procalcitonin (PCT), oxygenation index (PaO 2/FiO 2), alveolar artery oxygen differential pressure (P A-aDO 2) were recorded. During mechanical ventilation, the patient's body temperature, WBC, sputum characteristics, and the change of the lung ultrasound were dynamically observed. With or without dynamic air bronchogram, lung ultrasound was considered to be positive as long as there were small subpleural consolidation or tissue-like sign. Ventilator-associated pneumonia lung ultrasound score (VPLUS) and lung ultrasound score (LUSS) were performed, and chest CT scan was completed on the same day. Use positive chest CT scan as the standard to evaluate the diagnostic efficacy of lung ultrasound, VPLUS score, and the combination of the two with PCT for VAP. LUSS was used to assess the severity of disease in patients with VAP. The correlation between LUSS and PaO 2/FiO 2, P A-aDO 2, APACHEⅡscore and SOFA score were analyzed. Results:① General information: compared with non-VAP group, VAP group had more emergency surgery patients [51.7% (31/60) vs. 33.9% (21/62), P = 0.047], APACHEⅡ score and SOFA score were significantly higher (APACHEⅡscore: 15.4±5.7 vs. 13.4±3.4, P = 0.021; SOFA score: 8.8±4.2 vs. 6.3±3.3, P < 0.001), body temperature tended to rise (℃: 38.3±0.8 vs. 38.0±0.9, P = 0.054), more patients had airway purulent secretions [65.0% (39/60) vs. 41.9% (26/62), P = 0.011], and mechanical ventilation time and length of ICU stay were longer [mechanical ventilation time (days): 10.5 (6.6, 15.0) vs. 4.3 (3.0, 6.0), P < 0.001; length of ICU stay (days): 14.8 (9.0, 18.0) vs. 6.0 (4.0, 9.1), P < 0.001], 28-day mortality rate was higher [31.7% (19/60) vs. 9.7% (6/62), P = 0.003].② Diagnostic efficacy evaluation: when lung ultrasound was positive, VPLUS≥3 and PCT > 0.5 μg/L were used separately for the diagnosis of VAP, the sensitivity was 73.3%, 75.0%, 61.7%, respectively; the specificity was 80.6%, 58.1% and 59.7%, respectively; the 95% confidence interval (95% CI) was 0.685-0.842, 0.574-0.748, 0.514-0.694, respectively, all P < 0.05, positive lung ultrasound had good sensitivity and specificity. When positive lung ultrasound or VPLUS≥3 were combined with PCT > 0.5 μg/L for tandem test, the specificity of VAP diagnosis was increased to 95.2% and 83.9%, respectively; but the specificity of VAP diagnosis of positive lung ultrasound combined with PCT > 0.5 μg/L was higher than VPLUS ≥3 combined with PCT > 0.5 μg/L (95.2% vs. 83.9%, P < 0.05).③ Correlation analysis: LUSS showed a significant positive correlation with APACHEⅡ and SOFA score ( r values were 0.407, 0.399, P values were 0.001, 0.002, respectively), LUSS had no relation with PaO 2/FiO 2 and P A-aDO 2 ( r values were 0.189, -0.064, P values were 0.629, 0.149, respectively). Conclusions:Lung ultrasound can early detect VAP , and its diagnostic specificity is significantly improved when combined with PCT > 0.5 μg/L. LUSS is closely related to the severity of disease in VAP patients, therefore, lung ultrasound may be an effective method for early diagnosis and efficacy evaluation of VAP patients.

Abstract Objective　To explore the clinical status and correlation of ruminant thinking and sleep quality in isolated population during the COVID-19 epidemic. Methods　Insomnia Severity Index Scale （ISI） and Rumination Thinking Scale （RRS） were used to investigate 107 persons in a centralized isolation site in Deyang，Sichuan. Results　The detection rate of insomnia among isolated personnel was 37.4%. Correlation analysis showed that the total score of the RRS was positively correlated with the ISI （r=0.468，P<0.05）；the repeated deep thinking was positively correlated with the ISI （r=0.35，P<0.05）；the compulsive thinking dimension was positively correlated with the sleep ISI （r=0.382，P<0.05）；the depression-related dimension was positively correlated with the ISI （r=0.468，P<0.05）. Multivariate Logistic regression analysis showed that marriage was a risk factor for sleep disturbance （P<0.05）；however，increasing age was a protective factor （P<0.05）. Conclusion　Quarantined people are prone to sleep disorders during the epidemic，and ruminant thinking is strongly positively related to sleep disorders. For public health emergencies，improving ruminant thinking may have important research value for regulating sleep disorders.

Objective To analyze the clinical manifestations of familial acute necrotizing encephalopathy (ANE)and to improve the recognition of this disease. Methods The clinical data of a 25 - month - old girl with fa-milial and recurrent ANE with evidence of mutation in the RANBP2 gene were collected and analyzed,and the gene examination of their family members was performed. Results A previously healthy girl experienced recurrent ANE epi-sodes at the ages of 8 months,18 months and 25 months,respectively. At each beginning of each episodes the patient presented with lethargy and tremor of limbs following febrile illness of 3 - 4 days,even developed coma and convulsions in the last time. Brain magnetic resonance imaging showed bilateral and high T2 signal changes in thalamus,cerebellum and hippocampus. Abnormal signals also appeared in the brainstem,claustrum,corpus scallosum and cortex(temporal, parietal and cingulate)also appeared abnormal signals. Spinal MRI showed spinal cord involvement. The girl recovered after her first episode;she could speak but could not walk steadily after the second time;after the third episode,al-though she regained consciousness from coma,she could no longer speak or walk. The patient's sister died of encephali-tis at the age of 18 months. Her paternal uncle had suffered from dysnoesia from meningitis at his 17 months of age. The patient and her grandmother,father,uncle and one of her aunts harbored a mutation(c. 1754C ﹥ T)in RANBP2 gene. Conclusions Familial ANE has typical clinical manifestations and characteristic MRI findings. The patient with recur-rent history,especially with positive family history,should have the mutation in RANBP2 gene detected earlier in order to clarify the diagnosis of ANE.

BACKGROUNDSignificant efforts have been made to identify factors that differentiate patients treated with novel therapies, such as bortezomib in multiple myeloma (MM). The exact expression pattern and prognostic value of the cancer/testis antigen preferentially expressed antigen of melanoma (PRAME) in MM are unknown and were explored in this study.

METHODSThe transcript level of PRAME was detected in bone marrow specimens from 100 newly diagnosed MM patients using real-time quantitative polymerase chain reaction, and the prognostic value of PRAME was determined through retrospective survival analysis. PRAME expression higher than the upper limit of normal bone marrow was defined as PRAME overexpression or PRAME (+).

RESULTSSixty-two patients (62.0%) overexpressed PRAME. PRAME overexpression showed no prognostic significance to either overall survival (n = 100) or progression-free survival (PFS, n = 96, all P > 0.05) of patients. The patients were also categorized according to regimens with or without bortezomib. PRAME overexpression tended to be associated with a lower two-year PFS rate in patients treated with non-bortezomib-containing regimens (53.5% vs. 76.9%, P = 0.071). By contrast, it was not associated with the two-year PFS rate in patients with bortezomib-containing regimens (77.5% vs. 63.9%, P > 0.05). When the patients were categorized into PRAME (+) and PRAME (-) groups, treatment with bortezomibcontaining regimens predicted a higher two-year PFS rate in PRAME (+) patients (77.5% vs. 53.5%, P = 0.027) but showed no significant effect on two-year PFS rate in PRAME (-) patients (63.9% vs. 76.9%, P > 0.05).

CONCLUSIONPRAME overexpression might be an adverse prognostic factor of PFS in MM patients treated with non-bortezomib-containing regimens. Bortezomib improves PFS in patients overexpressing PRAME.
