BACKGROUND: Butylphthalide (NBP) and edaravone (EDV) injection are common acute ischemic stroke medications in China, but there is a lack of large real-world safety studies on them. This study aimed to determine the incidence of adverse events, detect relevant safety signals, and assess the risk factors associated with these medications in real-world populations. METHODS: In this study, data of acute ischemic stroke patients were extracted from the electronic medical record database of six tertiary hospitals between January 2019 and August 2021. Baseline confounders were eliminated using propensity score matching. The drugs' safety was estimated by comparing the results of 24 laboratory tests standards on liver function, kidney function, lipid level, and coagulation function. The drugs' relative risk was estimated by logistic regression. A third group with patients who did not receive NBP or EDV was constructed as a reference. Prescription sequence symmetry analysis was used to evaluate the associations between adverse events and NBP and EDV, respectively. RESULTS: 81,292 patients were included in this study. After propensity score matching, the NBP, EDV, and third groups with 727 patients in each group. Among the 15 test items, the incidence of adverse events was lower in the NBP group than in the EDV group, and the differences were statistically significant. The multivariate logistic regression equation revealed that NBP injection was not a promoting factor for abnormal laboratory test results, whereas EDV had statistically significant effects on aspartate transaminase, low-density lipoprotein cholesterol and total cholesterol. Prescription sequence symmetry analysis showed that NBP had a weak correlation with abnormal platelet count. EDV had a positive signal associated with abnormal results in gamma-glutamyl transferase, alanine aminotransferase, aspartate aminotransferase, prothrombin time, and platelet count. CONCLUSIONS In a large real-world population, NBP has a lower incidence of adverse events and a better safety profile than EDV or other usual medications.

ObjectivePeriprosthetic joint infections （PJI） are currently the most calamitous complication after arthroplasty. Although achievements have been made in many markers for the diagnosis of PJI， the lack of a gold standard remains a great obstacle for early diagnosis. This study aimed to investigate the association between coagulation markers and the development of PJI in patients undergoing revision total joint arthroplasty （TJA）. MethodsWe conducted a retrospective cohort study with a total of 2 517 patients who underwent hip or knee arthroplasties from January 2011 to January 2022 （2 394 with primary TJA， 87 with aseptic revision and 36 with PJI）. We applied univariate analysis and multivariate logistic regression to analyze differences of coagulation factors between primary TJA and aseptic revision or PJI group. Receiver operating characteristic （ROC） curve and area under the curve （AUC） were used to measure the diagnostic value of coagulation factors in predicting PJI. ResultsCoagulation factors and their ratios including plasma fibrinogen （FBG）， prothrombin time （PT）， thrombin time （TT）， activated partial thromboplastin time （APTT）， platelet （PLT）， mean platelet volume （MPV）， platelet distribution width （PDW）， plateletcrit （PCT）， PLT / MPV， PLT / PDW and PLT / PCT were included in this study. High FGB level was strongly correlated with the risk of PJI compared to other coagulation factors. The optimal threshold value of FBG was 4.53 g/L with a sensitivity of 47.22%， a specificity of 93.07% （Primary TJA group vs. PJI group）. Similarly， the optimal threshold value of FBG was 4.44 g/L with a sensitivity of 47.22%， a specificity of 95.40% between the other two groups （Aseptic revision group vs. PJI group）. ROC curve analysis demonstrated moderate diagnostic performance of FBG （AUC value）， indicating a potential to be a diagnostic marker for PJI. ConclusionsFBG is significantly correlated with PJI and it can be used as a potential non-invasive marker for early detection. It may serve as a safe and cost-effective tool for assessing PJI in clinical work.

Itch is an unpleasant sensation that provokes the desire to scratch. While acute itch serves as a protective system to warn the body of external irritating agents, chronic itch is a debilitating but poorly-treated clinical disease leading to repetitive scratching and skin lesions. However, the neural mechanisms underlying the pathophysiology of chronic itch remain mysterious. Here, we identified a cell type-dependent role of the anterior cingulate cortex (ACC) in controlling chronic itch-related excessive scratching behaviors in mice. Moreover, we delineated a neural circuit originating from excitatory neurons of the ACC to the ventral tegmental area (VTA) that was critically involved in chronic itch. Furthermore, we demonstrate that the ACC→VTA circuit also selectively modulated histaminergic acute itch. Finally, the ACC neurons were shown to predominantly innervate the non-dopaminergic neurons of the VTA. Taken together, our findings uncover a cortex-midbrain circuit for chronic itch-evoked scratching behaviors and shed novel insights on therapeutic intervention.

Objective: To investigate the safety and efficacy of embedding the stump of gastroduodenal artery between the left lateral lobe of the liver and the left caudate lobe to prevent bleeding after laparoscopic pancreaticoduodenectomy. Methods: The clinical data of 41 patients who underwent laparoscopic pancreaticoduodenectomy at the second Hospital of Hebei Medical University from October 2021 to April 2022 were analyzed retrospectively.There were 27 males and 14 females, aged (63.0±9.2)years (range: 48 to 78 years), and the body mass index was (24.1±3.2)kg/m² (range: 15.4 to 31.6 kg/m²). After routine laparoscopic pancreaticoduodenectomy, the stump of gastroduodenal artery was embedded between the left lateral lobe and the left caudate lobe of the liver, and the hepatic parenchyma of the left lateral lobe and the left caudate lobe were sutured with absorbable sutures.The occurrence and recovery of postoperative complications (pancreatic fistula, biliary fistula, postoperative abdominal bleeding, abdominal infection, liver abscess) were observed. Results: All the operations of 41 patients were completed successfully.The operation time was (277.5±52.0) minutes (range: 192 to 360 minutes). The entrapment time of gastroduodenal artery stump was (3.1±0.6) minutes (range: 2.3 to 4.2 minutes), and the intraoperative blood loss (M(IQR)) was 300 (200) ml (range: 50 to 800 ml).The results of ultrasound examination of hepatic artery on the first day after operation showed that the blood flows of hepatic artery were unobstructed.Postoperative pancreatic fistula occurred in 3 cases, including grade B pancreatic fistula in 2 cases (1 case with abdominal infection) and biochemical leakage in 1 case. Three patients with pancreatic fistula were discharged successfully after continuous abdominal drainage. There was no biliary fistula, abdominal bleeding, abdominal infection, liver abscess or postoperative liver dysfunction. Conclusion: The encasement of the gastroduodenal artery stump by the left outer and left caudate lobes of the liver may be an effective way to prevent bleeding from the rupture of the gastroduodenal artery stump after laparoscopic pancreatoduodenectomy, which is easy and safe to perform.

Objective: To explore the relationship between obesity status and death stratified by different multi-morbidity status in older adults in China. Methods: Data for older Chinese adults aged ≥65 years were from Chinese Longitudinal Healthy Longevity Survey (CLHLS). Multi-morbidity patterns based on 13 chronic conditions were explored using exploratory factor analysis. Cox models were used to examine relationships between obesity status and death stratified by disease count and multi-morbidity patterns at baseline, respectively. Besides, obesity status was defined by baseline body mass index and waist circumference. Results: A total of 6 272 participants were included in the analyses. Multi-morbidity including cardio-metabolic, sensory perception and other patterns were identified. For those without any chronic condition, compared with those without central obesity, central obesity was associated with a higher risk for death (HR=1.66, 95%CI:1.04-2.66). For those only with one chronic condition, compared with normal weight, underweight was associated with a higher risk for death (HR=1.41, 95%CI: 1.10-1.80). For those with multi-morbidity, compared with normal weight, underweight increased the risk for death (HR=1.19, 95%CI:1.05-1.34). Compared with those without central obesity, central obesity decreased the risk for death (HR=0.88, 95%CI:0.78-0.99). Conclusions: Relationships between obesity status and death varied by multi-morbidity status in older adults in China. Underweight and non-central obesity were associated with increased risks for death in older adults with only one chronic disease or multi-morbidity. Therefore, it is necessary to pay attention to multi-morbidity status in the management of obesity in older adults and provide effective targeted body weight management plan.

Inflammatory bowel disease (IBD) is an, intractable inflammatory autoimmune disease characterized by T-cell infiltration to the colon. Mesenchymal stem cells (MSCs), owing to their immunosuppressive capabilities, have the potential to rescue IBD. But the therapeutic effectiveness of MSCs is sometime thwarted by their variable immunomodulatory ability in vivo. In the present study, we produced engineered MSCs that secrete interleukin10 (IL-10) and evaluated their therapeutic potential in IBD mouse model. The MSCs maintained the phenotype and cell proliferation rate after overexpression of IL-10 by lentivirus (LV) infection. Immune cells and MSCs in vitro co-culture systems exhibited that relative to unmodified MSCs, immune cells co-cultured with IL-10-overexpressing MSCs had significantly lower numbers of T helper 1 cells (Th1) and T helper 17 cells (Th17) (P<0.05), the content of TNF-α in the supernatant of macrophage cells co-cultured with MSCs overexpressing IL-10 was significantly decreased (P<0.0001). Tail vein injection of the IL-10 overexpressing MSCs achieved a better therapeutic effect in the dextran sodium sulfate (DSS) induced colitis mouse model than that of the unmodified MSCs, as indicated by colon length, disease activity index (DAI) and colonic cytokines expression. The experimental results were statistically different (P>0.05). Overall, LV induced MSCs overexpressing IL-10 might be a promising alternative therapeutic option for the treatment of IBD.

Aim To establish subcutaneous and orthotopic transplantation models of human lung cancer in nude mice, and compare the anti-cancer effects of digoxin between the two models. Methods After subcutaneous inoculation of H460 tissues in nude mice, the tumor volume was measured; HE staining and immunohistochemistry were performed; H460-Luc cell suspension was injected into the lung of nude mice toestablish orthotopic tumor model, the in vivo imaging and fluorescence values were recorded, and the tumor lesions in other organs were observed after dissection. Results Compared with control group, the gemcitabine group had a significant anti-tumor effect (P <0.05), and digoxin groups had no significant difference (P > 0.05). HE staining showed that the cell density in each treatment group decreased, and necrosis and/or fibrous hyperplasia were obvious. Immunohistochemistry indicated that the protein expression of p-p38, p-ERK and Nur77 in each treatment group significantly increased in the subcutaneous transplantation model; in the orthotopic transplantation model, the gemcitabine, the middle (P < 0.05) and low dose of digoxin group could inhibit the tumor growth, while the high dose of digoxin group accelerated the development of tumor (P < 0.05). Conclusion Digoxin is more sensitive to orthotopic transplanted tumor than subcutaneous transplanted tumor, anddigoxin may inhibit the tumor growth by up-regulating the expression of p-p38, pERK and Nur77.

ObjectiveThe purpose of this study was to compare the expression of plasma vWF activity， ADAMTS-13 activity and neutrophil-to-lymphocyte ratio （NLR） between patients with acute pulmonary thromboembolism （PTE） and healthy controls， and to explore the clinical value of plasma ADAMTS-13 activity and NLR in diagnosis of acute PTE. MethodsTotally 64 patients with acute PTE and 30 healthy controls were included. Collected clinical data and detected the plasma vWF activity and ADAMTS-13 activity by enzyme linked immunosorbent assay （Elisa）. The correlation between ADAMTS-13 activity and other clinical indexes was explored. Receiver operating characteristic curve （ROC） was mapped to evaluate the activity of ADAMTS-13 and NLR in the diagnosis of patients with acute PTE. ResultsThe comparison between the healthy control group and the acute pulmonary thromboembolism group showed that the ADAMTS-13 activity levels were 83.8% （72.2%， 98.8%） and 63.3% （49.6%， 74.8%）， respectively， the VWF activity levels were 102.7% （89.7%， 117.2%） and 122.6% （96.8%， 156.6%）， respectively， and the differences between the two groups were statistically significant （P＜0.05）. Spearman correlation analysis showed that there was a negative linear correlation between ADAMTS-13 activity and vWF activity with D-dimer （P＜0.05）. The results of multivariate Logistic regression showed that the increase of NLR was an independent risk factor for acute PTE ［OR=1.66， 95% CI （1.10， 2.47）， P=0.014］ and the increase of ADAMTS-13 activity was an independent protective factor for acute PTE ［OR=0.92， 95% CI （0.88， 0.964）， P＜0.001］. When used in the diagnosis of acute PTE， the area under the curve （AUC） for ADAMTS-13 activity was 0.861， 95%CI （0.780， 0.942）， P＜0.001. When combined with NLR， the AUC was 0.902， 95%CI（0.841， 0.963）， P＜0.001. ConclusionsOur results show plasma ADAMTS-13 activity is significantly decreased and vWF activity is significantly increased in patients with acute PTE. ADAMTS-13 and vWF may be the bridge between thrombosis and inflammation. Combined with NLR， plasma ADAMTS-13 activity can improve the accuracy of diagnosis of acute PTE. Our results provide new ideas for exploring the pathogenic mechanism of acute PTE， and provide experimental basis for exploring therapeutic target of acute PTE.

Objective To evaluate the quality of reporting of clinical practice guidelines of rehabilitation.Methods A comprehensive retrieve was performed in electronic databases of PubMed, EMBASE, CNKI, China Biology Medicine disc, Wanfang data, etc., from January 1, 2017 to January 11, 2020. Supplementary searches had been done on relevant websites. Two researchers reviewed literatures and assessed the reporting quality independently by using Reporting Items for Practice Guidelines in Healthcare (RIGHT), and any disagreements needed to be discussed in a consensus meeting.Results A total of 16 guidelines were included, with an average reporting rate of (44.8±27.9)%. Among the seven domains of RIGHT, basic information was reported the highest (57.3%), and evidence (31.3%) and other information (31.3%) was the lowest. The reporting rate was less as the guidelines published in China than in foreign contries (OR = 0.80, 95%CI 0.56-1.16), in original version than in update version (OR = 0.79, 95%CI 0.54-1.16); and higher as developed by various societies or associations than developed by non-societies or associations (OR = 1.15, 95%CI 0.82-1.61), however, no statistically significant difference was found in above comparisons.Conclusion Current clinical practice guidelines of rehabilitation reported with low quality. It is proposed that future guideline developers should report guidelines after RIGHT statements, including key information and content, in order to improve the quality of reporting guidelines.
