Objective:To explore the current situation and influencing factors of quality of life of septic patients in intensive care unit (ICU) after discharge, and to provide theoretical basis for clinical early psychological intervention and continuity of care.Methods:A prospective observational study was conducted. The septic patients who were hospitalized in the department of critical care medicine of the Affiliated Hospital of Jining Medical University and discharged with improvement from January 1 to December 31, 2022 were selected as the research objects. The demographic information, basic diseases, infection site, vital signs at ICU admission, severity scores of the condition within 24 hours after ICU admission, various biochemical indexes, treatment process, and prognostic indexes of all the patients were recorded. All patients were assessed by questionnaire at 3 months of discharge using the 36-item short-form health survey scale (SF-36 scale), the activities of daily living scale (ADL scale), and the Montreal cognitive assessment scale (MoCA scale). Multiple linear regression was used to analyze the factors influencing the quality of life of septic patients after discharge from the hospital.Results:A total of 200 septic patients were discharged with improvement and followed up at 3 months of discharge, of which 150 completed the questionnaire. Of the 150 patients, 57 had sepsis and 93 had septic shock. The total SF-36 scale score of septic patients at 3 months of discharge was 81.4±23.0, and the scores of dimensions were, in descending order, role-emotional (83.4±23.0), mental health (82.9±23.6), bodily pain (82.8±23.3), vitality (81.6±23.2), physical function (81.4±23.5), general health (81.1±23.3), role-physical (79.5±27.0), and social function (78.8±25.2). There was no statistically significant difference in the total SF-36 scale score between the patients with sepsis and septic shock (82.6±22.0 vs. 80.7±23.6, P > 0.05). Incorporating the statistically significant indicators from linear univariate analysis into multiple linear regression analysis, and the results showed that the factors influencing the quality of life of septic patients at 3 months after discharge included ADL scale score at 3 months after discharge [ β= 0.741, 95% confidence interval (95% CI) was 0.606 to 0.791, P < 0.001], length of ICU stay ( β= -0.209, 95% CI was -0.733 to -0.208, P = 0.001), duration of mechanical ventilation ( β= 0.147, 95% CI was 0.122 to 0.978, P = 0.012), total dosage of norepinephrine ( β= -0.111, 95% CI was -0.044 to -0.002, P = 0.028), mean arterial pressure (MAP) at ICU admission ( β= -0.102, 95% CI was -0.203 to -0.007, P = 0.036) and body weight ( β= 0.097, 95% CI was 0.005 to 0.345, P = 0.044). Conclusions:The quality of life of patients with sepsis at 3 months after discharge is at a moderately high level. The influencing factors of the quality of life of patients with sepsis at 3 months after discharge include the ADL scale score at 3 months after discharge, the length of ICU stay, the duration of mechanical ventilation, the total dosage of norepinephrine, MAP at ICU admission and body weight, and healthcare professionals should enhance the treatment and care of the patients during their hospitalization based on the above influencing factors, and pay attention to early psychological intervention and continued care for such patients.

Objective:To explore the relationship between gratitude and academic burnout incollege students,as well as the role of psychological well-being and proactive coping in their relationship.Methods:A total of 1 038 college students from 4 universities were selected andassessedwith the Gratitude Scale(GQ-6),Flourishing Scale(FS),Proactive Coping Scale(PCS)and Maslach Burnout Inventory-General Survey(MBI-GS).SPSS macro pro-gram Process and Bootstrap method were used to test the mediating effect.Results:The MBI-GS scores were higher in boys than in girls(P＜0.01),and higher in those with left behind experience thanin those without left behind ex-perience(P＜0.001).The GQ-6 scores were negatively associated with the MBI-GS scores(β=-0.19,P＜0.001).PCS scores played an independent mediating role between GQ-6 scores and MBI-GS scores(Indirect effect=0.05,95％CI=0.02-0.09),while the scores of psychological well-being and proactive coping had a chain mediating effect between gratitude scores and academic burnout scores(Indirect effect=0.06,95％CI=0.03～0.01).Conclusion:It suggests that gratitude is related to academic burnout in college students,and proactive cop-ing plays an independent mediating role,while psychological well-being and proactive coping play a chain media-ting role.

Objective To investigate the characteristics of imaging signs of giant cell tumor(GCT)of the hand and foot bones.Methods The clinical,X-ray,CT and MRI images of 18 cases of GCT of hand and foot bones diagnosed by pathology were analyzed retrospectively.And compared with 54 cases of long bone GCT imaging manifestations.Results Among the 18 GCT cases of hand and foot bones,there were 8 cases of hand,10 cases of foot,including 12 cases of short tubular bone and 6 cases of tarsal bone.All lesions were dilatant osteolytic bone destruction involving the joint surface,in which the short tubular bone GCT showed central growth,the tumor occupied the entire wide diameter of the bone,the lesion range was long,consistent with the bone axis,easy to invade the surrounding soft tissue,sclerotic edge,bone ridge,lobed and periosteal reaction were rare,and prone to recurrence after surgery.The GCT of tarsal bone and short tubular bone showed eccentric growth,and there was statistical difference(P<0.05).The probability of pathological fracture in GCT of long bone was significantly greater than that of short tubular bone.There was no significant difference between the two groups in swelling growth,involvement of bone end and ethmoid sign of bone cortex.Conclusion Compared with long bone GCT,hand and foot bones are rare occurrence site of GCT,which is more aggressive than long bone GCT and prone to recurrence after surgery.Full attention should be paid to its imaging characteristics to provide more accurate image information for clinical treatment strategies.

Objective:To investigate the ultrasonic characteristics of lymph node metastasis of papillary thyroid carcinoma and the predictive value of silent mating-type information regulation2 homolog1 (SIRT1) .Methods:90 PTC patients admitted from May. 2022 to May. 2023 were selected. According to the ultrasonography of patients with lymph node enlargement, hypoecho, unclear boundary, microcalcification and other conditions, the patients were divided into 26 cases in the LNM group and 64 cases without LNM. All patients underwent thyroid ultrasonography, and their serum samples were collected. Serum SIRT1 levels were detected by enzyme-linked immunosorbent assay (ELISA) double-antibody sandwich method. ROC was used to analyze the predictive value of ultrasonic characteristics and serum SIRT1 for LNM in PTC patients.Results:Compared with the group without lymph node metastasis, the proportion of patients with multiple tumor lesions ( P=0.001), tumor diameter ≥1 cm, hypoecho, unclear boundary and microcalcification was higher in the group with lymph node metastasis ( P<0.05). The serum SIRT1 level of LNM group (5.12±1.24) ng/mL was lower than that of (8.76±1.35) ng/mL in the other group ( P<0.05). ROC results showed that when the optimal cut-off value of serum SIRT1 was 7.59 ng/mL, the area under the curve was 0.78 (95% CI: 0.746- 0.835). The sensitivity and specificity were 79.43% and 71.56%, respectively. Multiple tumors, tumor diameter ≥1 cm ( P=0.018), unclear boundaries ( P=0.005), microcalcification ( P=0.001), and serum SIRT1 < 7.59 ng/mL ( P<0.001) had good clinical value in the evaluation of lymph node metastasis of papillary thyroid carcinoma, and the combined detection had a higher predictive value, with a sensitivity of 84.57%. Multivariate analysis showed that tumor boundaries were unclear ( OR=2.812, 95% CI: 1.220-6.482), microcalcification ( OR=4.145, 95% CI: 1.335-12.870), and serum SIRT1 decreased ( OR=2.399, 95% CI: 1.580-3.642) were independent risk factors for lymph node metastasis of papillary thyroid carcinoma ( P<0.05) . Conclusions:Lymph node metastasis of papillary thyroid carcinoma is characterized by unclear boundary and micro-calcification on ultrasound, and serum SIRT1 is decreased. The combined detection of ultrasound features and serum SIRT1 has a good predictive value in predicting lymph node metastasis in patients with papillary thyroid cancer.

Objective:To investigate the risk factors of lower extremity deep venous thrombosis (LEDVT) in patients with sepsis during hospitalization in intensive care unit (ICU), and to construct a nomogram prediction model of LEDVT in sepsis patients in the ICU based on the critical care scores combined with inflammatory markers, and to validate its effectiveness in early prediction.Methods:726 sepsis patients admitted to the ICU of the Affiliated Hospital of Jining Medical University from January 2015 to December 2021 were retrospectively included as the training set to construct the prediction model. In addition, 213 sepsis patients admitted to the ICU of the Affiliated Hospital of Jining Medical University from January 2022 to June 2023 were retrospectively included as the validation set to verify the performance of the prediction model. Clinical data of patients were collected, such as demographic information, vital signs at the time of admission to the ICU, underlying diseases, past history, various types of scores within 24 hours of admission to the ICU, the first laboratory indexes of admission to the ICU, lower extremity venous ultrasound results, treatment, and prognostic indexes. Lasso regression analysis was used to screen the influencing factors for the occurrence of LEDVT in sepsis patients, and the results of Logistic regression analysis were synthesized to construct a nomogram model. The nomogram model was evaluated by receiver operator characteristic curve (ROC curve), calibration curve, clinical impact curve (CIC) and decision curve analysis (DCA).Results:The incidence of LEDVT after ICU admission was 21.5% (156/726) in the training set of sepsis patients and 21.6% (46/213) in the validation set of sepsis patients. The baseline data of patients in both training and validation sets were comparable. Lasso regression analysis showed that seven independent variables were screened from 67 parameters to be associated with the occurrence of LEDVT in patients with sepsis. Logistic regression analysis showed that the age [odds ratio ( OR) = 1.03, 95% confidence interval (95% CI) was 1.01 to 1.04, P < 0.001], body mass index (BMI: OR = 1.05, 95% CI was 1.01 to 1.09, P = 0.009), venous thromboembolism (VTE) score ( OR = 1.20, 95% CI was 1.11 to 1.29, P < 0.001), activated partial thromboplastin time (APTT: OR = 0.98, 95% CI was 0.97 to 0.99, P = 0.009), D-dimer ( OR = 1.03, 95% CI was 1.01 to 1.04, P < 0.001), skin or soft-tissue infection ( OR = 2.53, 95% CI was 1.29 to 4.98, P = 0.007), and femoral venous cannulation ( OR = 3.72, 95% CI was 2.50 to 5.54, P < 0.001) were the independent influences on the occurrence of LEDVT in patients with sepsis. The nomogram model was constructed by combining the above variables, and the ROC curve analysis showed that the area under the curve (AUC) of the nomogram model for predicting the occurrence of LEDVT in patients with sepsis was 0.793 (95% CI was 0.746 to 0.841), and the AUC in the validation set was 0.844 (95% CI was 0.786 to 0.901). The calibration curve showed that its predicted probability was in good agreement with the actual probabilities were in good agreement, and both CIC and DCA curves suggested a favorable net clinical benefit. Conclusion:The nomogram model based on the critical illness scores combined with inflammatory markers can be used for early prediction of LEDVT in ICU sepsis patients, which helps clinicians to identify the risk factors for LEDVT in sepsis patients earlier, so as to achieve early treatment.
