Objective:To investigate the predictive value of thrombus permeability for poor outcome and symptomatic intracranial hemorrhage (sICH) after endovascular therapy (EVT) in patients with middle cerebral artery occlusion stroke.Methods:Patients with middle cerebral artery occlusion stroke underwent EVT at the Cardiocerebrovascular Disease Hospital, the Affiliated Hospital of Yan'an University from January 2018 to January 2024 were included retrospectively. Thrombus attenuation increase (TAI) was used to evaluate thrombus permeability. The poor outcome was defined as a modified Rankin Scale score >2 at 90 days after procedure. sICH was defined as an increase of ≥4 of the National Institutes of Health Stroke Scale (NIHSS) score relative to baseline or lowest within 7 days after EVT, and CT scan showed cerebral hemorrhage. Multivariate logistic regression analysis was used to determine the independent influencing factors of poor outcome and sICH. Receiver operating characteristic (ROC) curves was used to evaluate the predictive value of TAI for poor outcome and sICH. Results:A total of 77 patients with middle cerebral artery occlusion stroke received EVT treatment were enrolled, including 44 males (57.1%), aged 62.1±12.4 years. Thirty-three patients (48.1%) had poor outcome, 35 (45.5%) experienced hemorrhagic transformation, of which 12 (15.6%) were sICH. Multivariate logistic regression analysis showed that TAI (odds ratio [ OR] 0.930, 95% confidence interval [ CI] 0.883-0.980; P=0.007) and sICH ( OR 0.868, 95% CI 0.784-0.961; P=0.006) were the independent influencing factors of poor outcome. ROC curve analysis showed that the area under the curve of TAI for predicting poor outcome at 90 days was 0.836 (95% CI 0.742-0.930). The cut-off value was 10.135 HU. The sensitivity and specificity were 73.0% and 92.5%, respectively. The area under the curve of TAI for predicting sICH was 0.750 (95% CI 0.637-0.902). The cut-off value was 18.200 HU. The sensitivity and specificity were 94.1% and 64.5%, respectively. Conclusions:TAI has certain predictive value for poor outcome and sICH after EVT in patients with middle cerebral artery occlusion stroke. Patients with higher thrombus permeability are less likely to develop sICH after EVT and have a higher likelihood of good outcome.

Protein phosphorylation plays a key role in Mycobacterium tuberculosis, the pathogen of tuberculosis, holding promise as a new target of anti-tuberculosis drugs. We used M. smegmatis, a close relative of M. tuberculosis, as a model organism to study the protein phosphorylation at different growth phases. We identified 573 phosphorylated peptides and 816 phosphorylated sites of 385 proteins in the M. smegmatis samples at both logarithmic and stationary phases, and then established a comprehensive dataset of phosphorylated proteins in M. smegmatis. By comparing the expression levels of phosphorylated proteins between the logarithmic and the stationary phase with the selected ion monitoring (SIM) strategy, we verified 68 upregulated proteins involved in cell division and protein translation, and 69 downregulated proteins mainly involved in the tricarboxylic acid cycle pathway. The differentially expressed phosphorylated proteins were significantly enriched in important cellular cycle events such as cell elongation and division. The findings of this study provide proteome evidence for elucidating the phosphorylation in both M. smegmatis and M. tuberculosis.

Despite growing prevalence and incidence, the management of gout remains suboptimal. The intermittent nature of the gout makes the long-term urate-lowering therapy (ULT) particularly important for gout management. However, patients are reluctant to take medication day after day to manage incurable occasional gout flares, and suffer from possible long-term toxicity. Therefore, a safe and easy-to-operate drug delivery system with simple preparation for the long-term management of gout is very necessary. Here, a chitosan-containing sustained-release microneedle system co-loaded with colchicine and uricase liposomes were fabricated to achieve this goal. This microneedle system was confirmed to successfully deliver the drug to the skin and maintain a one-week drug retention. Furthermore, its powerful therapeutic potency to manage gout was investigated in both acute gouty and chronic gouty models. Besides, the drug co-delivery system could help avoid long-term daily oral colchicine, a drug with a narrow therapeutic index. This system also avoids mass injection of uricase by improving its stability, enhancing the clinical application value of uricase. In general, this two-drug system reduces the dosage of uricase and colchicine and improves the patient's compliance, which has a strong clinical translation.

ObjectiveTo explore the clinical efficacy and safety of Qifu Yixin prescription in treating chronic heart failure in the patients with the syndrome of heart Qi deficiency, so as to provide clinical evidence for the treatment of chronic heart failure with this prescription and promote the clinical application and transformation of this prescription. MethodA total of 106 chronic heart failure patients with the syndrome of heart Qi deficiency who met the criteria in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine (TCM) from September 2022 to May 2023 were selected and randomized into an observation group (53 cases) and a control group (53 cases). Both groups received routine Western medicine treatment. In addition, the observation group received Qifu Yixin prescription, while the control group received placebo. The treatment course for both groups was 12 weeks. The New York heart association (NYHA) cardiac function grading, N-terminal pro-B-type natriuretic peptide (NT-proBNP), soluble growth-stimulating expression gene 2 (sST2), left ventricular ejection fraction (LVEF), the ratio of early diastolic maximum mitral flow velocity (E) to early diastolic mitral annular motion velocity (e') (E/e'), left ventricular end diastolic diameter (LVEDD), TCM syndrome scores, 6-minute walking test (6MWT), Minnesota Living with Heart Failure Questionnaire (MLHFQ), and Kansas City Cardiomyopathy Questionnaire (KCCQ) were determined before and after treatment. ResultFinally, 102 patients were included for analysis, including 51 patients in the observation group and 51 patients in the control group. After treatment, 42 patients in the observation group showed improved cardiac function grading, with a total response rate of 82.35%, and 32 patients in the control group showed improved cardiac function grading, with a total response rate of 62.75%. The total response rate regarding the cardiac function in the observation group was higher than that in the control group (χ2=4.923, P<0.05). The observation group outperformed the control group in lowering the NT-proBNP level, elevating LVEF, decreasing the E/e' ratio (P<0.05), reducing LVEDD and sST2 levels, and recovering TCM syndrome score, 6MWT score, MLHFQ score, and KCCQ score (P<0.05). None of the safety indexes in the two groups showed abnormal values before and after treatment, and no serious adverse reaction was observed. ConclusionQifu Yixin prescription can improve the heart function, exercise tolerance, and quality of life and alleviate the TCM syndrome of the chronic heart failure patients with the syndrome of heart Qi deficiency by inhibiting myocardial fibrosis.

The theory of "liver opens at the eyes" was first seen in Yellow Emperor's Internal Canon of Medicine, which is the ancient people's summary of the connection between the liver and the eyes. The theory of "liver opens at the eyes" suggests the characteristic of "co-damage and co-recover of liver and eyes". It has been found in clinical practice that liver diseases and eye diseases often occur together, and "liver and eyes co-recover" is an ideal choice. The key to achieving "liver and eyes co-recover" is to analyze its pharmacological material basis and mechanism. With the development of modern medicine, more and more evidence indicates that the liver and eyes have complex and close relationships in physiological and pathological aspects. In a pathological state, there is a phenomenon of "liver and eyes co-damage", and after the intervention of traditional Chinese medicine, "liver and eyes co-recover" occurs. "Liver and eyes co-damage and co-recover" can be explained through the "co-material basis and co-action mechanism". On this basis, the research group tentatively proposed that the liver and eyes had "four common characteristics" (4CCs), namely "co-damage, co-recover, co-material basis, and co-action mechanism" from the theoretical connotation of traditional Chinese medicine, clinical practice, and molecular biology. Additionally, the group also took the intervention of Prunella vulgaris, traditional Chinese medicine, for removing liver fire and improving eyesight on immune liver injury (ILI) and allergic conjunctivitis (AC) as examples to analyze 4CCs. This project aims to deeply analyze the scientific connotation of the theory of "liver opens at the eyes", reveal the common characteristics and biological essence of liver and eyes, explore a new research paradigm of "liver and eyes co-recover", and provide a reference for the study of common problems of multi-organ associated diseases.

Objective:To analyze the clinical characteristics of acute ischemic stroke (AIS) patients with negative cerebral CT perfusion (CTP) and influencing factors for their prognoses.Methods:A retrospective analysis was performed; 448 patients with AIS admitted to Department of Neurology, Sixth Affiliated Hospital of Nantong University from January 2020 to June 2021 were enrolled. CTP images of these patients were processed by RAPID software, and they were divided into CTP-negative group and CTP-positive group according to cerebral infarction core and ischemic penumbra volumes. The clinical data were compared between patients from CTP-negative group and CTP-positive group and between patients from CTP-negative and CTP-positive subgroups accepted thrombolytic therapy. According to the prognoses 3 months after discharge, CTP negative patients were divided into poor prognosis group and good prognosis group. Independent influencing factors for poor prognosis in negative CTP patients were analyzed by univariate and multivariate Logistic regressions.Results:(1) In these 448 patients, 154 (34.4%) were with negative CTP and 294 (65.6%) were with positive CTP; compared with the CTP-positive group, the CTP-negative group had significantly younger age, significantly higher percentage of patients with diabetes, significantly lower percentage of patients with atrial fibrillation, statistically higher baseline systolic blood pressure, and significantly lower baseline National Institutes of Health Stroke Scale (NIHSS) scores, early neurological deterioration (END) incidence, modified Rankin scale (mRS) scores 3 months after discharge, and proportion of patients with poor prognosis ( P<0.05); significant differences in distributions of responsible circulations for the lesions and etiological classification (TOAST) were noted between the 2 groups ( P<0.05). Of the 448 patients, 270 received thrombolytic therapy, including 101 CTP-negative patients and 169 CTP-positive patients; compared with the CTP-positive subgroup, the CTP-negative subgroup had significantly younger age, significantly lower percentage of patients with atrial fibrillation, statistically higher baseline systolic blood pressure, and significantly lower baseline NIHSS scores, END incidence, mRS scores 3 months after discharge, and proportion of patients with poor prognosis ( P<0.05). (2) Of the 154 CTP negative patients, 31 had poor prognosis and 123 had good prognosis. Univariate Logistic regression analysis showed that baseline blood glucose, fasting blood glucose, glycosylated hemoglobin (HbA1C), baseline NIHSS scores and fibrinogen were the influencing factors for prognoses of CTP negative patients, with significant differences ( P<0.05). Multivariate Logistic regression analysis found that NIHSS ( OR=0.827, 95% CI: 0.743-0.920, P<0.001) and HbA1 C ( OR=0.763, 95% CI: 0.609-0.956, P=0.019) were independent influencing factors for poor prognosis of CTP-negative patients. Conclusion:AIS patients with negative CTP have milder neurological impairment, better prognosis, and higher safety of receiving intravenous thrombolysis than those with positive CTP; AIS patients with negative CTP enjoying high baseline NIHSS scores and HBA1c have poor prognosis.

Urinary tract infection (UTI) is one of the most common infectious diseases. It has the characteristics of high recurrence rate and prolonged course. At present, the problem of antibiotic resistance is becoming more and more serious, the incidence of adverse reactions is high, and the disadvantages of long-term administration appear, which brings severe challenges to the treatment of recurrent urinary tract infection. The prevention and treatment of UTI recurrence has become the focus of research. Recurrent urinary tract infection is related to the immune regulation mechanism of the body. Administration of immune regulation can provide new ideas for prevention and treatment. The vaccine based on immune regulation to prevent rUTI has made some progress. It can not only reduce the frequency of recurrences, but also decrease related symptoms. At the same time, the vaccine has good tolerance, high safety and good application prospect. This paper aims to summarize the progress of immune regulation and immune vaccines in vivo and clinical research.
