Objective: To explore the mechanism of the Peiyuan Jieyu formula in treating depression by assessing its impact on a lipopolysaccharide-induced (LPS-induced) depression mouse model. Methods: We created a mouse model of depression by exposing mice that had previously received chronic stress to intraperitoneal LPS injections. The mice were divided into the following groups: control, model, fluoxetine, Tiansi Yin, Sini powder, and low-, medium-, and high-dose Peiyuan Jieyu formula groups. Forced swim and tail suspension tests were used to assess the efficacy of the depression (despair) model, and weight gain rates were also measured. Furthermore, serum levels of various depression and inflammation-associated molecules, including tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), tryptophan, 5-hydroxytryptamine, kynurenine (KYN), and kynurenic acid (KA) were assessed. Furthermore, the expression levels of ionic calcium-binding adaptor molecule-1 (IBA-1) and indoleamine 2,3-dioxygenase (IDO) mRNA in hippocampal microglia were measured. Results: The model group displayed greater despair-associated immobility, which was shortened in response to various doses of Peiyuan Jieyu formula. Furthermore, formula administration significantly reduced serum TNF-α levels and hippocampal IDO mRNA expression. The high formula dose also reduced IFN-γ and IBA-1 levels, the latter was also decreased in response to the medium formula dose. However, the low formula dose reduced serum KYN level and KYN/tryptophan (TRP) and KYN/KA ratios. Conclusion The Peiyuan Jieyu formula holds immense potential in treating depression in a mouse model, potentially inhibiting inflammation and improving TRP-KYN metabolic disorders.

Sepsis is a syndrome of systemic inflammatory response in which the body′s response to infection is dysregulated, and is characterized by persistent infection, excessive inflammation and immunosuppression, etc. It often leads to organ dysfunction and can be life threatening, and also a common complication after trauma. The pathogenesis of post-traumatic sepsis is still unclear at present due to the complexity of its etiology, progression and prognosis. Multi-omics technology is a method to combine two or more single omics for comprehensive analysis, which can reveal the interaction network among the disease-associated molecules from multiple perspectives and aspects and is of great significance for the analysis of the pathogenesis of post-traumatic sepsis. To this end, the authors reviewed the research progress on the role of multi-omics technology in elucidating the pathogenesis of post-traumatic sepsis from the perspectives of genomics, transcriptomics, proteomics, metabolomics, single-cell transcriptomics and combination of multi-omics technologies, etc so as to provide a reference for the researches on post-traumatic sepsis.

Venous thromboembolism (VTE) is a complication in children with acute lymphoblastic leukemia (ALL). The Chinese Children's Cancer Group-ALL-2015 protocol was carried out in China, and epidemiology, clinical characteristics, and risk factors associated with VTE were analyzed. We collected data on VTE in a multi-institutional clinical study of 7640 patients with ALL diagnosed in 20 hospitals from January 2015 to December 2019. First, VTE occurred in 159 (2.08%) patients, including 90 (56.6%) during induction therapy and 108 (67.92%) in the upper extremities. T-ALL had a 1.74-fold increased risk of VTE (95% CI 1.08-2.8, P = 0.022). Septicemia, as an adverse event of ALL treatment, can significantly promote the occurrence of VTE (P < 0.001). Catheter-related thrombosis (CRT) accounted for 75.47% (n = 120); and, symptomatic VTE, 58.49% (n = 93), which was more common in patients aged 12-18 years (P = 0.023), non-CRT patients (P < 0.001), or patients with cerebral thrombosis (P < 0.001). Of the patients with VTE treated with anticoagulation therapy (n = 147), 4.08% (n = 6) had bleeding. The VTE recurrence rate was 5.03% (n = 8). Patients with VTE treated by non-ultrasound-guided venous cannulation (P = 0.02), with residual thrombus (P = 0.006), or with short anticoagulation period (P = 0.026) had high recurrence rates. Thus, preventing repeated venous puncture and appropriately prolonged anticoagulation time can reduce the risk of VTE recurrence.

Objective:To evaluate the efficacy and safety of cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) in the treatment of pseudomyxoma peritonei (PMP).Methods:In this descriptive case series study, we retrospective analyzed the records of PMP patients treated with CRS and HIPEC between January 2013 and June 2023 at Affiliated Cancer Hospital and Institute of Guangzhou Medical University. The inclusion criteria were as follows: (1) Aged 18 to 75 years and nonpregnant women. (2) Histologically confirmed diagnosis of pseudomyxoma peritonei. (3) Karnofsky Performance Scale (KPS)>70. (4) The functions of major organs such as the heart, liver, lungs, and kidneys can tolerate major surgery for long periods of time. (5) No evidence of extra-abdominal metastasis. Patients with extensive intra-abdominal adhesions or severe infectious diseases were excluded. The main outcomes were overall survival (OS) and postoperative major complications. The postoperative major complications were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (version 5.0). We used the peritoneal cancer index (PCI) score to quantitatively assess the peritoneal metastases and the completeness of cytoreduction (CCR) score at the end of surgery (CCR-0 and CCR-1 considered to be complete CRS).Results:A total of the 186 PMP patients with a median age of 56 (interquartile range extremes (IQRE), 48-64) years were included, 65 (34.9%) males and 121 (65.1%) females. The median peritoneal cancer index (PCI) score was 28 (20-34). Appendiceal origin accounted for 91.4%. Histological types were low grade in 99 patients (53.2%), high grade in 57 patients (30.6%), and 55 patients (29.6%) received complete cytoreduction (CCR-0/1). The median operative duration was 300 (211-430) minutes for all patients. Treatment-related 30-day mortality was 2.7%; 90-day mortality 4.3%; reoperation 1.6%; and severe morbidity 43.0%. Within the entire series, anemia(27.4%), electrolyte disturbance(11.6%), and hypoalbuminemia(7.5%) were the most frequent major complications (grade 3-4). The incidences of gastrointestinal anastomotic leakage, abdominal bleeding, and abdominal infection were 2.2%, 2.2%, and 4.3%, respectively. After a median follow-up of 38.1 (95%CI:31.2-45.1) months, the 5-year OS was 50.3% (95%CI: 40.7%-59.9%) with a median survival time of 66.1 (95%CI: 43.1-89.1) months. The survival analysis showed that patients with pathological low grade, low PCI, and low CCR score had better survival with statistically significant differences (all P<0.05). Further stratified into complete and incomplete CRS subgroups, the 5-year OS of the CCR-0 and CCR-1 subgroups was 88.9% (95%CI: 68.3%-100.0%) and 77.6% (95%CI: 62.7%-92.5%), respectively; and 42.0% (95%CI: 29.5%-54.5%) in the CCR-2/3 subgroup. Conclusions:CRS and HIPEC may result in a long-term survival benefit for PMP patients with acceptable perioperative morbidity and mortality. This strategy, when complete CRS is possible, could significantly prolong survival for strictly selected patients at experienced centers.

Objective:To evaluate the efficacy and safety of vedolizumab (VDZ) in the treatment of active ulcerative colitis (UC).Methods:From November 1, 2020 to October 30, 2022, at the Department of Gastroenterology, the Sixth Affiliated Hospital of Sun Yat-sen University, 81 UC patients who received VDZ treatment and completed a 14-week follow-up were retrospectively selected. The clinical data of patients, including age, disease duration, disease activity of UC were collected. The VDZ efficacy evaluation included primary and secondary efficacy indicators. The primary efficacy indicator was the clinical remission rate after 14 weeks of VDZ treatment, and the secondary efficacy indicators included the clinical response rate, steroids-free remission rate, endoscopic remission rate after 14 weeks of treatment as well as the clinical response rate, clinical remission rate, steroids-free remission rate, secondary loss of response rate after 52 weeks of treatment. The adverse reactions during the treatment were recored. Taking clinical remission after 14 weeks of treatment as the dependent variable, univariate analysis was performed to identify the risk factors affecting clinical remission of VDZ. Binary logistic regression analysis was used for multivariate analysis to determine the independent risk factors of VDZ-included clinical remission. Chi-square test and Wilcoxon signed-rank test were used for statistical analysis.Results:Among the 81 UC patients, the age was 40.0 years old (29.0 years old, 53.5 years old) and the disease duration was 42.5 months (22.5 months, 94.7 months). The proportion of patients with mild active UC was 21.0% (17/81), the proportion of patients with moderate active UC was 64.2% (52/81), and the proportion of patients with severe active UC was 14.8% (12/81). After 14 weeks of treatment, the total Mayo score decreased from baseline level of 7.0 (6.0, 9.0) to 1.0 (0.0, 3.0), and the difference was statistically significant ( Z=-6.87, P<0.001). The clinical response rate was 84.0% (68/81) and the clinical remission rate was 69.1% (56/81) after 14 weeks of treatment. Of the 17 patients treated with combination of corticosteroid therapy, 10 achieved steroid-free remission, and the endoscopic remission rate was 34.8% (23/66). Of the 43 patients followed up to 52 weeks, the total Mayo score of UC patients decreased from baseline level of 7.0 (6.0, 9.0) to 0.0 (0.0, 1.0) after 52 weeks of treatment, and the difference was statistically significant ( Z=-3.25, P<0.001). The clinical response rate was 69.8% (30/43), and the clinical remission rate was 65.1% (28/43). Of the 13 patients treated with combination of corticosteroid therapy, 10 patients achieved steroid-free remission. The secondary loss of response rate was 15.2%(5/33) .The result of the univariate analysis showed that previous use of glucocorticoids was a risk factor of clinical remission after 14 weeks of VDZ treatment ( χ2=5.88, P=0.015). The result of multivariate logistic regression analysis showed that previous use of glucocorticoids was an independent risk factor of clinical remission after 14 weeks of VDZ treatment ( OR=3.429, 95% confidence interval 1.235 to 9.517, P=0.014). During the follow-up period, 12.3% (10/81) of patients developed Clostridium difficile infections, except for 1 case stopped VDZ treatment because the clinical response was not reached, remaining 9 cases continued VDZ treatment after received anti- Clostridium difficile treatment. Conclusion:VDZ has good clinical efficacy and safety in the treatment of Chinese UC patients, and patients with no history of glucocorticoid use may be more likely to achieve clinical remission after 14 weeks of treatment.

Objective:To investigate the perioperative complications and risk factors of postoperative death in patients with acute Stanford type A aortic dissection (ATAAD).Methods:The perioperative data of 228 patients with ATAAD who underwent continuous surgery in the Affiliated Hospital of Jining Medical University from January 2013 to July 2021 were retrospectively analyzed. The complications were analyzed. According to the survival within 30 days after surgery, they were divided into death group (24 cases) and survival group (204 cases). The risk factors of postoperative death were analyzed by univariate and multivariate logistic regression. The receiver operating characteristic (ROC) curve was drawed to evaluate the predictive efficacy of various risk factors on postoperative death of ATAAD patients.Results:The first three complications before operation were hypoxemia (10.1%, 23/228), pericardial tamponade (7.9%, 18/228), renal insufficiency (5.3%, 12/228), the first three complications after surgery were hypoxemia (75.8%, 173/228), renal insufficiency (26.8%, 61/228) and liver insufficiency (26.3%, 60/228). A total of 24 patients died, the fatality rate was 10.5%(24/228). Logistic regression analysis showed that age≥55 years old ( OR=7.733, 95% CI: 1.986-30.111, P=0.003), preoperative pericardial tamponade ( OR=5.641, 95% CI: 1.546-20.577, P=0.009), cardiopulmonary bypass time (CBP)≥200 min ( OR=1.008, 95% CI: 1.002-1.014, P=0.007) and postoperative renal insufficiency ( OR=5.875, 95% CI: 1.927-17.907, P=0.002) were independent risk factors for early death after ATAAD. The area under the ROC curves of joint prediction was 0.905 (95% CI: 0.820-0.950, P<0.01). The sensitivity and specificity of joint prediction were 88.4%, 76.5%, respectively. Conclusions:ATAAD has many perioperative complications and high mortality. Age≥55 years old, preoperative pericardial tamponade, CPB time≥200 min, and postoperative renal insufficiency were independent risk factors for postoperative death in ATAAD patients.

Mantle cell lymphoma (MCL) is a distinct histological type of B-cell lymphoma with a poor prognosis. Several agents, such as proteasome inhibitors, immunomodulatory drugs, and inhibitors of B cell lymphoma-2 and Bruton's tyrosine kinase have shown efficacy for relapsed or refractory (r/r) MCL but often have short-term responses. Chimeric antigen receptor (CAR) T-cell therapy has emerged as a novel treatment modality for r/r non-Hodgkin's lymphoma. However, long-term safety and tolerability associated with CAR T-cell therapy are not defined well, especially in MCL. In this report, we described a 70-year-old patient with r/r MCL with 48-month duration of follow-up who achieved long-term remission after CAR T-cell therapy. CAR T-cell-related toxicities were also mild and tolerated well even in this elderly patient. This report suggested that CAR T-cell therapy is a promising treatment modality for patients with MCL, who are generally elderly and have comorbid conditions.

Objective: To investigate the value of texture analysis based on diffusion-weighted magnetic resonance imaging (DWI) in the differential diagnosis of atypically enhanced small hepatocellular carcinoma (sHCC) and dysplastic nodules (DNs) in liver cirrhosis. Methods: Data of 59 cases with atypical enhancement and solitary cirrhotic nodule (≤2 cm) confirmed by dynamic contrast enhanced MRI and surgical pathology specimen were analyzed retrospectively. Among them, 37 cases were of atypically enhanced sHCC and 22 cases of DNS. The DWI signal characteristics of the lesions were analyzed to measure the average apparent diffusion coefficient (ADC) value of the lesions, and the ADC ratio of the lesion to the liver parenchyma. MaZda software was used to manually draw the region of interest to extract the texture parameters of DWI lesions. The three sets (combination of Fisher coefficient, classification of error probability combined with average correlation coefficient and interactive information) were used to select the thirty optimal texture parameters. Raw data analysis (RDA), principal component analysis (PCA), linear discriminant analysis (LDA) and non-linear discriminant analysis (NDA) were performed for texture classification. The difference of ADC value and ADC ratio between sHCC and DNS group was compared by independent sample t-test, and χ2 test was used to compare the count data (or rate). ROC curve analysis was used to evaluate the diagnostic efficiency. Results: The sensitivity, specificity and accuracy of DWI high-signal in the identification of atypically enhanced sHCC and DNs were 94.6% (35/37), 68.2% (15/22), and 84.7% (50/59), respectively. The ADC ratio of atypically enhanced sHCC was significantly lower than DNs, and the difference was statistically significant (t = 2.99, P = 0.002). The sensitivity, specificity, and accuracy for the diagnosis of atypically enhanced sHCC were 73.0% (27/37), 72.7% (16/22) and 72.9% (43/59), respectively. The sensitivity, specificity and accuracy of DWI texture analysis in diagnosing atypically enhanced sHCC were 94.6% (35/37), 95.5% (21/22) and 94.9% (56/59).The diagnostic efficiency of DWI texture analysis (AUC = 0.94) was significantly higher than DWI high-signal (AUC = 0.81) and ADC ratio (AUC = 0.72). Conclusion The texture analysis based on DWI can identify atypically enhanced sHCC and dysplastic nodules under the background of cirrhosis, and its efficacy is better than qualitative and quantitative DWI.
