Objective To study the course of development of aneurysm of abdominal aorta (AAA) with nonsurgical treatment in senile patients. Methods 37 subjects were included in the study, and they were divided into 3 groups according to the size of aneurysm observed at the first visit. The diameter of aneurysm was measured, and the measurement was repeated at periodic follow up. The yearly increase of the diameter was calculated and analyzed. Results For the 37 patients, the AAA mean diameter was 4.68cm at the first visit. The period of follow-up was 0.5 to 11 years, with a mean of 6.1 years. The average yearly increase in tumor diameter was 0.47cm/year. 14 patients with aneurysm diameter of 6.0cm had an average increase of 0.67cm/year. 5 patients died during the follow-up period, 2 of them died of rupture of the aneurysm, the diameter of which was 8.35cm and 8.91cm, respectively. Endoaneurysmorrhaphy with stent was performed in 7 patients. Conclusion The size of AAA in the senile patients increased slowly if the aneurysm diameter is 6.0 cm, the tumor size might increase quickly, and active intervention is recommended.

Aim To study the effect of rhein on renal damage induced by aristolochic acid. Methods Ze-brafish model of aristolochic acid nephropathy, genera-ted by treating zebrafish larvae with aristolochic acid for 24 h, was treated with rhein simultaneously . Mor-pholigical changes were observed and the creatinine level in larvae tissue was measured. And mRNA ex-pression levels of inflammatory factor cox2 a and fibrosis factor TGF-β1 in larvae tissue were detected using qPCR. Results Some larvae show periocular edema and circulation system defection e. g. weak heart beat, narrow cardiac vesicle, decreased blood flow and even blockage , with a dose-response relationship after expo-sure to aristolochic acid for 24 h. The creatinine level in larvae tissue of the treated group was significantly higher than that of the control larvae. And the expres-sion levels of cox2 a and TGF-β1 in larvae tissue of the treated group were also significantly increased. Per-centage of abnormal larvae and creatinine level in lar-vae tissue were decreased when treated with rhein sim-ultaneously. And the expression levels of cox2a was down-regulated by rhein compared with the aristolochic acid treated group. But rhein had no effect on TGF-β1 expression. Conclusion To some extent rhein can protect renal from damage induced by aristolochic acid.

Objective:To investigate the risk factors and predictive value of early neurological deterioration (END) in patients with minor stroke caused by middle cerebral artery occlusion.Methods:Consecutive patients with minor stroke caused by middle cerebral artery occlusion admitted to Zhangjiagang Hospital Affiliated to Soochow University from October 2021 to May 2023 were retrospectively included. Minor stroke was defined as the National Institutes of Health Stroke Scale (NIHSS) score ≤5 at admission, and END was defined as an increase of ≥4 from baseline in the NIHSS score within 24 h of admission (excluding intracranial hemorrhage). Multivariate logistic regression analysis was used to determine independent risk factors for END. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of various risk factors on END. Results:A total of 130 patients with minor stroke caused by middle cerebral artery occlusion were included, of which 33 (25.4%) had END and 97 (74.6%) did not. Univariate analysis showed that there were statistically significant differences in NIHSS scores, volume with cerebral blood flow <30%, CT perfusion mismatch volume, baseline blood glucose, and baseline white blood cell count between the END and non-END groups (all P<0.05). Multivariate logistic regression analysis showed that CT perfusion mismatch volume (odds ratio [ OR] 1.010, 95% confidence interval [ CI] 1.003-1.017; P=0.007) and baseline white blood cell count ( OR 1.582, 95% CI 1.200-2.085; P=0.001) were the independent risk factors for END. ROC curve analysis showed that the area under the curves of CT perfusion mismatch volume and baseline white blood cell count for predicting END were 0.748 (95% CI 0.660-0.835; P<0.001) and 0.757 (95% CI 0.659-0.854; P<0.001), respectively. The area under the curve of combined predicting END was 0.821 (95% CI 0.738-0.905; P<0.001). Conclusions:CT perfusion mismatch volume and baseline white blood cell count are independent risk factors for the occurrence of END patients with minor stroke caused by middle cerebral artery occlusion, and the combination of the two has good predictive value for END.

Objective To review the clinical characteristics and risk factors of Pseudomonas aeruginosa bloodstream infections. Methods The clinical data of P. aeruginosa bloodstream infections in the First Affiliated Hospital of Soochow University from January 2007 to December 2016 were analyzed retrospectively. Results Of the 251 patients identified, APACHE Ⅱ score on admission was 11.5±5.2. Majority (98.4%, 247/251) of the patients had fever. Leukopenia was found in 125 patients, leukocytosis in 87 patients, neutropenia in 122 patients, agranulocytosis in 113 patients, anemia in 193 patients, and hypoalbuminemia in 120 patients. Overall, 219 patients had at least one underlying disease, primarily hematological malignancy, or malignant solid tumor. Most (229) patients received invasive procedures such as deep venous catheter, urinary catheter, mechanical ventilation before blood sampling. P. aeruginosa was isolated from 108 of the 173 deep venous catheters. In addition, 130 patients received radiation or chemotherapy. Immunosuppressive agents were used in 124 patients. Among the 251 strains of P. aeruginosa, 87.3% were susceptible to amikacin, followed by ciprofloxacin (85.7%) and cefepime (81.6%). Multidrug-resistant P. aeruginosa was isolated from 36 (14.3%) patients, and extensively drug resistant strain was isolated from 7 patients. All the 251 patients were treated withantimicrobial agents, mainly β-lactam/β-lactamase inhibitor combinations, carbapenems or fluoroquinolones. Overall, 20 (8.0%) of the 251 patients died, 37 (14.7%) refused further therapy due to worsening condition, and 194 (77.3%) improved. Binary logistic regression analysis showed that high APACHE Ⅱ score on admission, anemia and hypoalbuminemia were risk factors for poor outcome of bloodstream infectionscaused by P. aeruginosa. Conclusions P. aeruginosa bloodstream infection occurs more readily in immunocompromised patients. High APACHE Ⅱ score on admission, anemia and hypoalbuminemia are associated with poor prognosis. Appropriate empiric antimicrobial treatment as early as possible can improve the prognosis of P. aeruginosa bloodstream infection.

Kunxian Capsule (KX) is a popular Chinese patent medicine for the treatment of rheumatoid arthritis, nephrotic syndrome, systemic lupus erythematosus, Henoch-Schönlein purpura, ankylosing spondylitis, psoriatic arthritis and eczema. However, there is scarcity of comprehensive information on the significance of KX in the clinical application and its side effects. Hence, it is aimed to provide a review of the significance of KX, with a focus on the pharmacological effects, clinical applications, and its adverse reactions. This review was based on the published literatures in PubMed, China National Knowledge Infrastructure and WanFang database. The articles were collected by two independent authors with no time limits applied until November 30, 2022. The search term includes Kunxian Capsule and/or clinical effect, pharmacology, disease, therapy, adverse effects and quality control. KX has been shown to be effective in the treatment of autoimmune arthritis by inhibiting inflammatory responses and inducing apoptosis. Many studies suggest that KX has anti-inflammatory and analgesic properties that aid in the improvement of joint functions. KX dispels wind, removes dampness, invigorates the kidneys, and promotes blood circulation, thereby curing various diseases. However, studies also suggest KX-related adverse reactions in multiple systems. Overall, this review highlights the scientific basis of KX in curing or preventing various diseases and provides novel insights for further research and clinical applications.
