Objective To investigate the status of work fatigue of the disabled and the healthy so that we get to know their employment quality and compressive strength, and then provide the theory basis for the national policy formulation and vocational rehabilitation. Methods We randomly investigated 280 employees (220 disabled, 60 healthy people) in 3 companies from 3 provinces with Fatigue Impact Scale (FIS). Results There was no statistically significant difference between disabled and healthy people about work fatigue, and also that of 3 domains including psycho-social, cognitive and physical activity. After comparison of 40 items on FIS，the disabled had higher fatigue than that of the healthy in 4 items which belonged to psycho-social domain (P<0.05). Conclusion Disabled people are no less than healthy people in compression capability and working capability. They should believe in themselves, and their family and the employees should have more confidence about their work capability than before. Government should provide some support with them on job retention.

Objective: To compare the treatment effect of surgical clipping and endovascular coil embolization for aneurysmal subarachnoid hemorrhage (aSAH) in the elderly. Methods: Elderly patients with aSAH (aged >65 years) treated in Shanghai Pudong Hospital from January 2009 to December 2017 were enrolled retrospectively. They were divided into craniotomy clipping group and endovascular intervention group according to the treatment strategy. The Glasgow Outcome Scale was used for short-term outcome assessment at discharge, 4-5 were defined as good outcome, and 1-3 were defined as poor outcome. Long-term follow-up was performed to assess clinical outcomes using the modified Rankin Scale, 0-2 was defined as good outcome and 3-6 were defined as poor outcome. The clinical and imaging information, perioperative complications, short-term and long-term clinical outcomes, and long-term imaging outcomes were compared between the two groups. Multivariate logistic regression analysis was used to assess the independent influencing factors of clinical outcomes. Results: A total of 68 elderly patients with aSAH were enrolled. Of these, 47 (69.1%) received endovascular coil embolization and 21 (30.9%) underwent microsurgical clipping. There were no significant differences between the two groups in the incidence of perioperative complications, short-term and long-term adverse outcomes, and imaging recurrence rate. Multivariate logistic analysis showed that smoking (odds ratio [OR] 36.319, 95% confidence interval [CI] 3.530-373.640; P=0.003), modified Fisher grade (OR 20.406, 95% CI 2.022-205.964; P=0.011) and World Federation of Neurological Societies (WFNS) grade (OR 4.686, 95% CI 1.012-21.692; P=0.048) were the independent risk factors for short-term poor outcomes in elderly patients with aSAH. Conclusion Both endovascular intervention and microsurgical clipping are safe and effective treatments for elderly patients with aSAH.

Objective:To investigate the prognosis value of baseline contrast-enhanced CT in predicting progression-free survival (PFS) and overall survival (OS) for clinically diagnosed as metastatic far-advanced gastric cancer patients.Methods:Between January 2019 and May 2020, 85 pathologically confirmed gastric adenocarcinoma patients with peritoneal or hepatic metastasis at Shanghai Ruijin Hospital with complete preoperative clinical, image and follow-up data were enrolled in this retrospective study. Clinical factors included performance status (PS) score, tumor location, and tumor serological indicators. Imaging factors included the longest diameter and maximum cross-sectional area of the tumor, CT value, enhancement uniformity, CT extramural venous invasion (ctEMVI), the largest short diameter of the metastatic lymph nodes, confluent lymph nodes, lymph nodes necrosis, fused bulk lymph nodes, the maximum cross-sectional area and CT value of the liver metastases, peritoneal metastasis score, longest diameter of nodules with peritoneal metastasis. Kaplan-Meier survival curve and log-rank test were used to analyze the prognostic differences between groups. Univariate and multivariate Cox proportional hazards regression models were used to identify independent risk factors for PFS and OS.Results:There were significant differences in the maximum cross-sectional area of the tumor, non-contrast CT value, delayed-phase CT value, and delayed-phase CT ratio value between the high- and low-risk groups in PFS ( P<0.05). There were significant differences between the high- and low-risk groups with the maximum cross-sectional area of the tumor in PFS and OS ( P<0.05). In the univariate analysis, the maximum cross-sectional area of tumor, plain-scan CT value, delayed-phase CT value, delayed-phase CT ratio value and the largest short diameter of metastatic lymph nodes were risk factors for PFS ( P<0.05). PS score, CA724, maximum cross-sectional area of the tumor, maximum cross-sectional area of liver metastases, and peritoneal metastasis score were shown as risk factors for OS ( P<0.05). In the multivariate analysis, the maximum cross-sectional area of the tumor and non-contrast CT value were independent risk factors for PFS (HR=0.41, 2.50, P<0.05, 0.006). PS score, CA724 and peritoneal metastasis score were independent risk factors for OS (HR=46.78, 6.26, 92.92, P=0.026, 0.009, 0.007). Conclusions:Tumor size, CT attenuations, and peritoneal metastasis score on baseline CT can be used as independent risk factors for survival in patients with far-advanced gastric cancer with peritoneal or hepatic metastasis. Baseline CT is potentially useful in prediction of the survival status for patients with metastatic far-advanced gastric cancer.

Objective:To verify the clinical safety and efficacy of new intelligent ventilation mode adaptive minute ventilation (AMV)+IntelliCycle ventilation in patients with mild-to-moderate acute respiratory distress syndrome (ARDS).Methods:The patients with mild-to-moderate ARDS, admitted to intensive care unit (ICU) of the First Affiliated Hospital of Jinzhou Medical University from February 2018 to February 2019, were enrolled in the study. The patients were divided into synchronous intermittent mandatory ventilation+pressure support ventilation (SIMV+PSV) group and AMV+IntelliCycle group according to the random number table method. All patients were given mechanical ventilation, anti-infection, analgesia and sedation, nutritional support and symptomatic treatment of primary disease after admission. SV800 ventilator was used for mechanical ventilation. In the AMV+IntelliCycle group, after setting the minute ventilation volume (VE), inhaled oxygen concentration (FiO 2) and positive end expiratory pressure (PEEP), the ventilator was turned on the full-automatic mode, and the preset value of VE percentage was 120%. In the SIMV+PSV group, the ventilator parameters were set as follows: the ventilation frequency was 12-20 times/min, the inspiratory expiratory ratio was 1∶1-2, the peak inspiratory pressure (PIP) limit level was 35-45 cmH 2O (1 cmH 2O = 0.098 kPa), and the setting of FiO 2 and PEEP was as the same as that of AMV+IntelliCycle group, the triggering flow was set to 2 L/min. All of the clinical parameters between the two groups were compared. The main outcomes were duration of mechanical ventilation, ventilator alarm times, manual operation times, and the mechanical power; the secondary outcomes were respiratory rate (RR), VE, tidal volume (VT), PIP, mouth occlusion pressure (P0.1), static compliance (Cst), work of breathing (WOB), and time constant at 0, 6, 12, 24, 48, 72, and 120 hours; and the blood gas analysis parameters of patients before and after ventilation were recorded. Results:A total of 92 patients with mild-to-moderate ARDS were admitted during the study period, excluding those who quit the study due to death, abandonment of treatment, accidental extubation of tracheal intubation and so on. Eighty patients were finally enrolled in the analysis, with 40 patients in SIMV+PSV group and AMV+IntelliCycle group respectively. ① Results of main outcomes: compared with the SIMV+PSV mode, AMV+IntelliCycle ventilation mode could shorten the duration of mechanical ventilation (hours: 106.35±55.03 vs. 136.50±73.78), reduce ventilator alarm times (times: 10.35±5.87 vs. 13.93±6.87) and the manual operations times (times: 4.25±2.01 vs. 6.83±3.75), and decrease the mechanical power (J/min: 12.88±4.67 vs. 16.35±5.04, all P < 0.05). But the arterial partial pressure of carbon dioxide (PaCO 2) of AMV+IntelliCycle group was significantly higher than that of SIMV+PSV group [mmHg (1 mmHg = 0.133 kPa): 41.58±6.81 vs. 38.45±5.77, P < 0.05]. ② Results of secondary outcomes: the RR of both groups was improved significantly with the prolongation of ventilation time which showed a time effect ( F = 4.131, P = 0.005). Moreover, compared with SIMV+PSV mode, AMV+IntelliCycle mode could maintain a better level of RR, with intervention effect ( F = 5.008, P = 0.031), but no interaction effect was found ( F = 2.489, P = 0.055). There was no significant difference in VE, PIP, P0.1 or Cst between the two groups, without intervention effect ( F values were 3.343, 2.047, 0.496, 1.456, respectively, all P > 0.05), but they were significantly improved with the prolongation of ventilation time in both groups, with time effect ( F values were 2.923, 12.870, 23.120, 7.851, respectively, all P < 0.05), but no interaction effect was found ( F values were 1.571, 1.291, 0.300, 0.354, respectively, all P > 0.05). The VT, WOB or time constant in both groups showed no significant changes with the prolongation of ventilation time, and no significant difference was found between the two groups, there was neither time effect ( F values were 0.613, 1.049, 2.087, respectively, all P > 0.05) nor intervention effect ( F values were 1.459, 0.514, 0.923, respectively, all P > 0.05). Conclusion:AMV+IntelliCycle ventilation mode can shorten the ventilation time of patients with mild-to-moderate ARDS, reduce mechanical power, and reduce the workload of medical care, but PaCO 2 in the patients with AMV+IntelliCycle mode is higher than that in the patients with SIMV+PSV mode.

BackgroundObsessive-compulsive personality disorder and obsessive-compulsive disorder （OCD） are common psychological disorders with similar clinical symptoms， but the differences between the two need further clarification. ObjectiveTo explore the clinical features of and influencing factors of obsessive-compulsive personality disorder in patients with OCD， so as to provide references for further relevant clinical diagnosis and treatment. MethodsA total of 195 patients with OCD were selected as the research subjects， who received treatment at the outpatient and inpatient departments of the Affiliated Brain Hospital of Nanjing Medical University from July 2022 to December 2023 and met the diagnostic criteria for OCD in the International Classification of Diseases， tenth edition （ICD-10）. Evaluation was conducted by using the Yale-Brown Obsessive Compulsive Scale （Y-BOCS）， Personality Diagnostic Questionnaire-4+ （PDQ-4+）， Obsessive-Compulsive Inventory-Revised （OCI-R）， Beck Depression Inventory （BDI）， Beck Anxiety Inventory （BAI） and Sheehan Disability Scale （SDS）. In accordance with the score of Obsessive-Compulsive Personality Disorder Scale in PDQ-4+， patients were divided into the OCD group with obsessive-compulsive personality disorder （n=58） and the OCD group without obsessive-compulsive personality disorder （n=137）. Pearson correlation analysis and Spearman correlation analysis were adopted to examine the correlation between clinical features and the score of the Obsessive-Compulsive Personality Disorder Scale. Multiple linear regression analysis was used to explore the influencing factors of OCD patients with obsessive-compulsive personality disorder. ResultsStatistically significant differences were observed between OCD patients with and without obsessive-compulsive personality disorder in the age， family history of mental illness， time without treatment， hoarding and ranking dimension scores in OCI-R， OCI-R total score， score of Obsessive-Compulsive Personality Disorder Scale in PDQ-4， and BDI score （P≤0.05）. OCD patients with obsessive-compulsive personality disorder in the time without treatment， OCI-R total score， hoarding and ranking dimension scores in OCI-R and BDI score are all positively correlated with the score of the Obsessive-Compulsive Personality Disorder Scale （r=0.120， 0.526， 0.364， 0.492， 0.414， P<0.05）. The results of multiple linear regression analysis showed that time without treatment （β=0.132， P<0.05）， hoarding dimension score （β=0.283， P<0.05） and ranking dimension score in OCI-R （β=0.418， P<0.05） were the influencing factors of OCD patients with obsessive-compulsive personality disorder. ConclusionOCD patients with obsessive-compulsive personality disorder may have longer untreated periods， more pronounced functional impairments in hoarding and sorting and more severe depressive symptoms. Untreated time， hoarding symptoms and sorting symptoms may be influencing factors for OCD patients with obsessive-compulsive personality disorder. ［Funded by Jiangsu Province Science and Technology Project （number， BE2021616；number， BE2022678）； Key Project of Nanjing Medical Science and Technology Development Fund （number， ZKX20029）］

Oral squamous cell carcinoma (OSCC) develops on the mucosal epithelium of the oral cavity. It accounts for approximately 90% of oral malignancies and impairs appearance, pronunciation, swallowing, and flavor perception. In 2020, 377,713 OSCC cases were reported globally. According to the Global Cancer Observatory (GCO), the incidence of OSCC will rise by approximately 40% by 2040, accompanied by a growth in mortality. Persistent exposure to various risk factors, including tobacco, alcohol, betel quid (BQ), and human papillomavirus (HPV), will lead to the development of oral potentially malignant disorders (OPMDs), which are oral mucosal lesions with an increased risk of developing into OSCC. Complex and multifactorial, the oncogenesis process involves genetic alteration, epigenetic modification, and a dysregulated tumor microenvironment. Although various therapeutic interventions, such as chemotherapy, radiation, immunotherapy, and nanomedicine, have been proposed to prevent or treat OSCC and OPMDs, understanding the mechanism of malignancies will facilitate the identification of therapeutic and prognostic factors, thereby improving the efficacy of treatment for OSCC patients. This review summarizes the mechanisms involved in OSCC. Moreover, the current therapeutic interventions and prognostic methods for OSCC and OPMDs are discussed to facilitate comprehension and provide several prospective outlooks for the fields.
