Objective To investigate the effects of endogenous sulfur dioxide(SO2) on pulmonary vascular inflammation in rats with monocrotaline (MCT)-induced pulmonary hypertension.Methods Thirty-two Wistar rats were randomly divided into 4 groups(n =8 for each group):control group,MCT group,MCT + L-aspartic acid-β-hydroxamate(HDX) group,and MCT + SO2 group.Rats in the MCT group,MCT + HDX group,and MCT + SO2 group were subcutaneously injected with MCT(60 mg/kg) on the first day.For rats in MCT + HDX group,HDX(25 mg/kg,on day 0,7 and 14) was given orally after injection of MCT; and rats in MCT + SO2 group were subcutaneously injected with the SO2 donor sodium sulfite/sodium bisulfate(Na2SO3/NaHSO3,and mole ratio was adjusted to approximately 3:1) each day.Rats in the control group received only the same volume of solvent vehicle only.After 3 weeks,mean pulmonary artery pressure(mPAP) of each rat was evaluated by using a right cardiac catheterization procedure.Immunohistochemistry was used to detect the expression of inflammatory related factor intercellular adhesion molecule-1 (ICAM-1) and the key molecules of nuclear factor-κB (NF-κB) signal transduction pathway,including p65 and inhibitor of NF-κB (IκBα) in the small pulmonary artery endothelial cells.Results The differences in mPAP,expression of ICAM-1,IκBα and p65 in the small pulmonary artery endothelial cells were found among the 4 groups (mPAP:F =53.334,P ＜ 0.01 ; ICAM-1:F =183.82,P ＜ 0.01 ; IκBα:F =142.89,P ＜ 0.01 ; p65:F =105.46,P ＜0.01).The mean pulmonary artery pressure(mPAP) was significantly raised in MCT group rats as compared with that of the control group along with upregulated expressions of ICAM-1 protein and p65 protein in small pulmonary artery endothelial cells,while the expression of IκBα protein in small pulmonary artery endothelial cells was significantly low.After administration of HDX,the mPAP and the expression of ICAM-1 protein and p65 protein in small pulmonary artery endothelial cells further increased compared with those of MCT group,while the expression of IκBα protein in small pulmonary artery endothelial cells was significantly lower than that of MCT group.Whereas with treatment of SO2 derivatives,the mPAP,the expression of ICAM-1 protein and p65 protein in small pulmonary artery endothelial cells were significantly lower than those of MCT group,while the expression of IκBα protein in small pulmonary artery endothelial cells increased significantly compared with that of MCT group.Conclusions Endogenous SO2 might inhibit the activation of NF-κB pathway in the small pulmonary artery endothelial cells,attenuate the pulmonary vascular inflammation and prevent the MCT-induced pulmonary hypertension in rats.

Objective:To analyze the incidence and risk factors of non-acute symptomatic portal vein thrombosis (PVT) after endoscopic gastric variceal injection (GVI) in the treatment of liver cirrhosis with gastric variceal bleeding (GVB).Methods:66 patients with GVB who were treated with GVI for the first time from July 2017 to October 2019 in Minhang Hospital Affiliated to Fudan University were retrospectively analyzed. The data of gender, age, preoperative Child-Pugh grade, preoperative platelet count, preoperative plasma D-dimer concentration, preoperative splenic length, preoperative portal vein velocity, preoperative splenic vein velocity, preoperative portal vein diameter, preoperative splenic vein diameter, treatment times, total number of injection points, total dose of sclerosing agent and tissue adhesive agent were collected. The patients were divided into PVT group and non-PVT group according to the occurrence of non-acute symptomatic PVT within one year after GVI. Univariate analysis was performed first, and then the factors with P<0.2 were included in the binary logistic regression model to screen the risk factors of PVT after GVI. Results:There were 25 cases (37.88%) in PVT group and 41 cases (62.12%) in non-PVT group. There were significant differences in D-dimer concentration, spleen length, Child-Pugh grade and total dose of sclerosing agent between the two groups ( P<0.05). The D-dimer concentration ( OR=2.319, 95% CI:1.359-3.956), spleen length ( OR=1.044, 95% CI:1.007-1.081) and total dose of sclerosing agent ( OR=1.075, 95% CI:1.004-1.152) were independent risk factors for PVT ( P<0.05). Conclusions:Preoperative D-dimer concentration, spleen length and total dose of sclerosing agent can predict the risk of PVT after GVI. In order to reduce the risk of PVT after GVI, the dose of sclerosing agent should be reduced as much as possible.

Objective:To investigate the status and the relationship of social support, depression, personality and sleep quality in patients with malignant bone tumors and their relationship, and provide scientific basis for postoperative rehabilitation and nursing.Methods:186 patients with malignant bone tumors undergoing chemotherapy in orthopedics department of the Second Xiangya Hospital of Central South University from January 2017 to December 2019 were selected to complete the Center for Epidemiological Studies Depression Scale (CES-D), the Perceived Social Support Scale (PSSS), the Optimism-Pessimism Scale (OPS), and the Pittsburgh Sleep Quality Index (PSQI). The demographic differences of various variables were compared and the correlation among social support, personality, sleep quality and depression in patients with malignant bone tumors were tested. Then, by structural equation model, the mediating role of personality and sleep quality between social support and depression was analyzed.Results:The incidence of depression in patients with malignant bone tumors was 57.6%(107/186), and the incidence of severe depression was 14.7%(27/186). Depression in patients with malignant bone tumors was negatively correlated with scores of social support and pessimism (all P<0.01), and positively correlated with scores of optimism and sleep quality (all P<0.05); Family support, pessimism, sleep quality and daytime dysfunction can effectively predict depression in patients with malignant bone tumors (all P≤0.05); Structural equation model analysis showed that personality and sleep quality play a chain mediating role between social support and depression. Conclusions:The incidence of depression is higher in patients with malignant bone tumors. Family support, pessimism, sleep quality and daytime dysfunction are predictors of depression in patients with malignant bone tumors. Personality and sleep quality play a chain mediating role in the influence of social support on depression.

Objective To analyze clinical prognosis, risk factors and predictive indexes of hyperkalemia in recipients after heart transplantation. Methods Clinical data of 158 recipients were retrospectively analyzed. According to the serum potassium levels within postoperative 1-year follow-up, all recipients were divided into the normal serum potassium level group (n=83), hyperkalemia group (n=43) and severe hyperkalemia group (n=32). The incidence and prognosis of hyperkalemia after heart transplantation were summarized. The risk factors and predictive indexes of hyperkalemia after heart transplantation were identified. Results The incidence of hyperkalemia and severe hyperkalemia within postoperative 1 year was 47.5%(75/158) and 20.3%(32/158), respectively. In the severe hyperkalemia group, the fatality was 16%(5/32), higher than 8%(7/83) in the normal serum potassium level group and 7%(3/43) in the hyperkalemia group. The mean serum creatinine (Scr) within 6 months before heart transplantation, the final total bilirubin level before heart transplantation, postoperative hemodialysis time, the Scr level and N-terminal pro-brain natriuretic peptide level at postoperative 1 d were the independent risk factors for hyperkalemia following heart transplantation (all P < 0.05). The mean Scr level within 6 months before heart transplantation, postoperative hemodialysis time, and Scr levels at postoperative 1 and 7 d could be used to predict postoperative severe hyperkalemia. Conclusions The recipients with severe hyperkalemia after heart transplantation obtain poor prognosis. The mean Scr level within 6 months before heart transplantation, the final total bilirubin level before heart transplantation, postoperative hemodialysis time, and the Scr level and N-terminal pro-brain natriuretic peptide level at postoperative 1 d are the independent risk factors for hyperkalemia after heart transplantation. Perioperative Scr level and postoperative hemodialysis time may be used to predict the incidence of severe hyperkalemia within 1 year after heart transplantation.

Objective: To explore the longitudinal changes and related predictive factors of anxiety and intolerance of uncertainty (IU) among Chinese college students, so as to provide theoretical reference for promoting students mental health. Methods: Intolerance of Uncertainty Scale-short Form and the 7 item Generalized Anxiety Disorder Scale were administered among 5 683 students from 22 universities in Guangdong Province from September 10 to October 17, 2021 (T1, baseline survey), and from March 15 to April 22, 2023 (T2). Using paired sample t-test to analyze the changes in anxiety and IU among college students, a linear regression model was established to explore factors that can predict anxiety, IU and their changes during T1 and T2 periods. Results: During the T1 period, the average scores of anxiety and IU among college students were (3.26±3.46, 34.88±7.96), while during the T2 period, they were (4.41±4.16, 36.40±8.07). During the T2 period, the levels of anxiety and IU among college students were higher than those during the T1 period ( t=19.59, 13.67, P <0.01). The linear regression results showed that age ( B = -0.02 ), moderate ( B =-0.18) and poor ( B =-0.88) mental health status, as well as online browsing of Corona Virus Disease 2019 (COVID-19) epidemic (later called as epidemic) related information for >1-<3 hours ( B =-0.30) and ≥3 hours ( B =-0.22), all of which could negatively predict changes in anxiety during T1 to T2 periods. Living in rural areas ( B =0.11) could positively predict changes in anxiety during T1 to T2 periods ( P <0.05). Moderate ( B =-0.19) and poor ( B =-0.47) mental health status, browsing epidemic related information online for >1-<3 hours ( B =-0.32) and ≥3 hours ( B =-0.33), academic performance being moderately affected by the epidemic ( B =-0.10), and personal planning being moderately affected by the epidemic ( B =-0.13) and severely affected ( B =-0.22), all of which could negatively predict changes in IU during T1 to T2 periods ( P <0.05). Conclusions Levels of anxiety and intolerance of uncertainty increases significantly after epidemic. Mental health status of college students should need long term monitoring, and students with poor mental health should need special attention.

Objective:To investigate the level of psychological resilience in patients with mouth neoplasms, analyze its influencing factors and find the mediating variables affecting the psychological resilience of patients with mouth neoplasms so as to provide basis for improving the psychological adaptation of patients with mouth neoplasms.Methods:Using the convenient sampling method, a total of 230 patients with mouth neoplasms from 2 ClassⅢ Grade A hospitals in Shenyang from May 2016 to October 2017 were selected as the research objects. The general situation questionnaire, Psychological Resilience Scale, Herth Hope Scale, Revised Life Orientation Test, Perceived Social Support Scale and Perceived Stress Scale-10 were used to investigate the psychological status of the research objects.Results:The score of psychological resilience of 230 patients with mouth neoplasms was (67.93±12.65) , which was in the middle level. The psychological resilience level of patients with mouth neoplasms was positively correlated with their hope level, optimism level and perceived social support level ( P<0.01) , but negatively correlated with perceived stress level ( P<0.01) . The influencing factors of psychological resilience in patients with mouth neoplasms included education level, hope and optimism, which could explain the variation of psychological resilience of patients with mouth neoplasms in 48.2% ( P<0.05) . Among them, the hope was the complete mediating variable of the relationship between social support level, stress perception level and psychological resilience of patients with mouth neoplasms, and the partial mediating variable of the relationship between optimistic level and psychological resilience. Conclusions:Hope is a key variable affecting psychological resilience in patients with mouth neoplasms. It is necessary to take targeted measures to promote the good psychological adaptation of patients by improving the hope level of patients.

Objective:To investigate the clinical application and effect of orbicularis oculi muscle shaping in lower blepharoplasty.Methods:A retrospective analysis was performed on the clinical data of 32 cases of flabby blepharoplasty patients admitted to the Orthopedic Surgery Clinic of Sichuan people＇s Hospital from October 2018 to September 2019. At the same time of transcutaneous blepharoplasty, 32 patients were treated with orbicularis oculi muscle shaping to remove the relaxed orbicularis oculi muscle, to reconstruct the annular strength and shape of the orbicularis oculi muscle, to strengthen the supporting structure of the lower eyelid, to reset the relationship between the external canthus orbicularis muscle and the skin, and then to reconstruct the soft tissue filling degree of the lower eyelid margin. The safety, efficacy and stability of the operation were evaluated by Barton grading, postoperative complications and scoring before and after operation and satisfactory analysis based on patients＇ satisfaction scale after operation.Results:All the patients were free of postoperative infection and healed at stage I. There were 2 cases of ecchymosis, 3 cases of ocular foreign body sensation, and no cases of infection, lower eyelid retraction, lower eyelid ectropion, or retrobulbous hematoma. The mean Barton score of all patients before surgery was 1.88±0.49, and the mean Barton score after surgery was 0.53±0.51. The t-test showed that the difference was statistically significant ( t=15.75, P<0.05), and the postoperative lacrimal groove deformity was improved. According to the score of satisfaction scale, 7 people were basically satisfied (21.88%) and 25 people were very satisfied (78.12%). Conclusions:Forming in the orbicularis oculi muscle relaxation eyelid bag type of prosthesis, in addition to the part of the orbicularis oculi muscle relaxation, deformation, and widely shed canthus outside skin and orbicularis connection, make the next eyelid edge to reproduce the full shape, obviously the bulging under the eyelid relaxation, the shape of the degree of repair, lateral canthus wrinkles tail department have also improven, restoring the full eyelid platform. The operation has strong pertinence, simple procedures, less complications and better long-term effect.

Objective:To investigate the biological behavior spectrum of platelet-derived growth factor alpha receptor (PDGFRA)-mutant gastrointestinal stromal tumor (GIST), and to compare the clinical values of the Zhongshan method of benign and malignant evaluation with the modified National Institutes of Health (NIH) risk stratification.Methods:A total of 119 cases of GIST with PDGFRA mutation who underwent surgical resection at Zhongshan Hospital, Fudan University from 2009 to 2020 were collected. The clinicopathological data, follow-up records, and subsequent treatment were reviewed and analyzed statistically.Results:There were 79 males and 40 females. The patients ranged in age from 25 to 80 years, with a median age of 60 years. Among them, 115 patients were followed up for 1-154 months, and 13 patients progressed to disease. The 5-year disease-free survival (DFS) and overall survival (OS) were 90.1% and 94.1%, respectively. According to the modified NIH risk stratification, 8 cases, 32 cases, 38 cases, and 35 cases were very-low risk, low risk, intermediate risk, and high risk, and 5-year DFS were 100.0%, 95.6%, 94.3%, and 80.5%, respectively. There was no significant difference in prognosis among the non-high risk groups, only the difference between high risk and non-high risk groups was significant ( P=0.029). However, the 5-year OS was 100.0%, 100.0%, 95.0% and 89.0%, and there was no difference ( P=0.221). According to the benign and malignant evaluation Zhongshan method, 43 cases were non-malignant (37.4%), 56 cases were low-grade malignant (48.7%), 9 cases were moderately malignant (7.8%), and 7 cases were highly malignant (6.1%). The 5-year DFS were 100.0%, 91.7%, 77.8%, 38.1%, and the difference was significant ( P<0.001). The 5-year OS were 100.0%, 97.5%, 77.8%, 66.7%, the difference was significant ( P<0.001). Conclusions:GIST with PDGFRA gene mutation shows a broad range of biological behavior, ranging from benign to highly malignant. According to the Zhongshan method, non-malignant and low-grade malignant tumors are common, the prognosis after surgery is good, while the fewer medium-high malignant tumors showed poor prognosis after surgical resection. The overall biological behavior of this type of GIST is relatively inert, which is due to the low proportion of medium-high malignant GIST. The modified NIH risk stratification may not be effective in risk stratification for PDGFRA mutant GIST.

Mesenchymal stem cells have emerged as a promising cell therapy for anti-tumor research due to their homing properties,low immunogenicity,anti-angiogenic activity,anti-inflammatory properties,and paracrine effects.Paclitaxel has been clinically used for over thirty years in the treatment of various tumors such as ovarian cancer,lung cancer,and breast cancer.However,the broad-spectrum anti-tumor properties of paclitaxel are not possessed by the aforementioned cell therapies.Moreover,its adverse reactions,including peripheral neuropathy,bone marrow suppression,and gastrointestinal reactions,have long plagued cancer patients.In recent years,many studies have focused on combining cell therapy with chemotherapy to achieve better treatment outcomes,giving rise to a new drug delivery system that utilizes mesenchymal stem cells as carriers for delivering chemotherapeutic drugs.This review summarizes the research progress in MSC-based drug delivery systems for paclitaxel.
