The aim of this study is to investigate the protective effect of idebenone (IDE) combined with borneol (BO) against Parkinson's disease (PD). In this study, wild-type AB zebrafish and transgenic Tg ( vmat2: GFP) zebrafish with green fluorescence labeled dopamine neurons were used to establish the PD model with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine hydrochloride (MPTP). Following drug treatment, the behavioral performance and dopamine neuron morphology of zebrafish were evaluated, and regulation of dopamine signaling pathway-related genes was determined using RT-qPCR. The results showed that IDE combined with BO improved the behavioral disorders of zebrafish such as bradykinesia and shortening movement distance, also effectively reversed the damage of MPTP-induced dopaminergic neurons. At the same time, the expression of dopamine synthesis and transportation-related genes was up-regulated, and the normal function of the signal transduction pathway was restored. The combination showed a better therapeutic effect compared to the IDE monotherapy group. This study reveals the protective mechanism of IDE combined with BO on the central nervous system for the first time, which provides an important experimental basis and theoretical reference for clinical combination strategy in PD treatment.

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.

Objective:To analyze the difference of clinical characteristics and outcomes of infants with moderate and severe pediatric acute respiratory distress syndrome(PARDS)diagnosed according to baseline oxygenation index(OI) in pediatric intensive care unit(PICU).Methods:Second analysis of the data collected from the "Efficacy of pulmonary surfactant (PS) in the treatment of children with moderate and severe ARDS" program.Retrospectively compare of the differences in clinical data such as general condition, underlying diseases, OI, mechanical ventilation, PS administration and outcomes among infants with moderate and severe PARDS divided by baseline OI who admitted to PICUs at 14 participating tertiary hospitals from 2016 to December 2021.Results:Among the 101 cases, 55 cases (54.5%) were moderate and 46 cases (45.5%) were severe PARDS.The proportion of male in the severe group (50.0% vs.72.7%, P=0.019) and the pediatric critical illness score(PCIS)[72 (68, 78) vs.76 (70, 80), P=0.019] were significantly lower than those in the moderate group, while there was no significant difference regarding age, body weight, etiology of PARDS and underlying diseases.The utilization rate of high-frequency ventilator in the severe group was significantly higher than that in the moderate group (34.8% vs.10.9%, P=0.004), but there was no significant difference in PS use, fluid load and pulmonary complications.The 24 h OI improvement (0.26±0.33 vs.0.04±0.34, P=0.001) and the 72 h OI improvement[0.34 (-0.04, 0.62) vs.0.15 (-0.14, 0.42), P=0.029)]in the severe group were significantly better than those in the moderate group, but there was no significant difference regarding mortality, length of hospital stay and intubation duration after diagnosis of PARDS between the two groups. Conclusion:In moderate and severe(divided by baseline OI) PARDS infants with invasive mechanical ventilation, children in severe group have better oxygenation improvement in the early stage after PARDS identified and are more likely to receive high frequency ventilation compared to those in moderate group.Baseline OI can not sensitively distinguish the outcomes and is not an ideal index for PARDS grading of this kind of patient.

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 explore changes in high-risk sexual behaviors and associated factors in HIV-infected men who have sex with men (MSM) in industrial workers, and provide evidence for designing behavioral interventions for this population.Methods:In this observational study, HIV-infected MSM were recruited in industrial workers using convenient sampling during August to September 2021. The sample size was estimated to be 530. A questionnaire was used and combined with routine follow-up to collect socio-demographic characteristics, high-risk sexual behaviors, partner notification, viral load testing and history of sexually transmitted diseases before and after diagnosis of HIV infection. The χ2 test was used to analyze the changes in high-risk sexual behaviors before and after diagnosis and logistic regression was conducted to identify factors associated with high-risk sexual behaviors. Results:A total of 560 HIV-infected MSM in industrial workers were recruited in this study. Of whom, 32.1% (180/560) had unprotected anal intercourse (UAI) within 12 months after diagnosis . The proportions of those having UAI with casual, commercial and regular same-sex partners significantly decreased from 73.4% (381/519), 75.1% (187/249) and 69.5% (207/298) within 12 months before diagnosis to 36.2% (146/403), 40.2% (86/214) and 34.2% (67/196) within 12 months after diagnosis , respectively. Educational level of college or above (a OR=0.41, 95% CI:0.23-0.71), passive anal sex (a OR=0.40, 95% CI:0.19-0.85), both active and passive anal sex after diagnosis (a OR=0.40, 95% CI:0.20-0.83) and no unprotected oral sex (a OR=0.02, 95% CI:0.01-0.05) were negatively associated with UAI within 12 months after diagnosis. Whereas, not considering necessary to use condom consistently after having repeated undetectable viral load (a OR=3.02, 95% CI:1.37-6.69) was positively associated with UAI within 12 months after diagnosis. Conclusions:Compared with that before diagnosis of HIV infection, although the prevalence of UAI seemed to decrease in HIV-infected MSM in industrial workers after diagnosis, nearly one third of them had high-risk sexual behaviors. Therefore, relevant interventions should be strengthened to reduce high-risk sexual behaviors.

Objective:To explore the cognition of the "undetectable equals untransmittable" ("U=U") concept and associated factors among HIV-infected men who have sex with men (MSM) receiving antiviral treatment (ART) in Shenzhen, and provide evidence for designing promotion and advocacy strategies for the "U=U" concept.Methods:We recruited HIV-infected MSM receiving ART using convenient sampling method combined with routine follow-up in Shenzhen through conducting observational survey. The sample size was estimated to be 475. A questionnaire was administered to collect socio-demographic characteristics, sexual behaviors, ART, viral load testing and the cognition towards "U=U" in HIV-infected MSM. Logistic regression was used to access factors associated with acceptance of "U=U".Results:A total of 490 HIV-infected MSM receiving ART were recruited. Of whom, 60.2% (295/490) were aware of "U=U" and 50.6% (248/490) accepted "U=U". Multiple logistic regression showed that participants who had an educational level of college or above (a OR=1.76,95% CI: 1.12-2.75) were more likely to accept "U=U". Those who had no local residency (a OR=0.51,95% CI: 0.29-0.92), had viral load >0 copies/ml in the last testing (a OR=0.61,95% CI: 0.38-0.98) and were unaware of "U=U" (a OR=0.13, 95% CI: 0.09-0.21), were less likely to accept "U=U". Conclusions:HIV-infected MSM receiving ART had a low cognition level of "U=U" in Shenzhen. Promotion and advocacy on this concept through healthcare workers should be enhanced in combination with routine follow-up in order to improve their ART adherence and outcome of treatment. Furthermore, developing related guidelines on "U=U" according to the characteristics of HIV-infected individuals is warranted to improve the normalization of promotion and advocacy on "U=U".

Objective:To investigate the risk factors for death in children with acute necrotizing encephalopathy (ANE) in pediatric intensive care unit (PICU).Methods:This was a multicenter retrospective study. Thirty-nine children with ANE were from PICUs in 4 centers from December 1, 2014 to December 1, 2020. The 4 participating centers were Beijing Children′s Hospital, Shengjing Hospital of China Medical University, Hebei Children′s Hospital, and Bao′an Maternity & Child Health Hospital. Patients were divided into survival and non-survival groups by the outcome at discharge, and the differences in clinical data between the two groups were compared. Risk factors for death in children with ANE and the odds ratios ( OR) were analyzed by univariable Logistic regression. Results:Thirty-nine children with ANE were included. There were 18 males and 21 females. The median onset age was 30 months. The mortality at discharge was 41% (16/39). The onset age of most patients (74%, 29/39) was younger than 4 years old. Influenza virus was the most common precursor infection (80%, 20/25). Patients with shock at PICU admission were more common in the non-survival group (12/16 vs. 17% (4/23), P=0.001). Glasgow coma score (GCS) at PICU admission was significantly lower in the non-survival group than survival group (3 (3, 6) vs. 6 (5, 7), Z=-2.598, P=0.009). The optimal cut-off value was 4. The proportion of patients with GCS ≤ 4 at PICU admission was higher in the non-survival group (10/16 vs. 22% (5/23), P=0.018). ANE severity score (ANE-SS) at PICU admission was significantly higher in the non-survival group (5 (2, 6) vs. 2 (1, 4), Z=-2.436, P=0.015). The proportion of patients with high risk ANE-SS was higher in non-survival group than the survival group (9/16 vs. 22% (5/23), P=0.043). The proportion of application of high-dose methylprednisolone (20 mg/(kg·d)) was significantly higher in survival group than non-survival group (43% (10/23) vs. 1/13, P=0.031). Univariable Logistic regression indicated that risk factors for death in children with ANE were shock ( OR=14.250, 95% CI 2.985-68.018, P=0.001), GCS≤4 ( OR=6.000, 95% CI 1.456-24.733, P=0.013) and high risk ANE-SS ( OR=4.629, 95% CI 1.142-18.752, P=0.032) at PICU admission. Conclusions:ANE usually occurs in children under 4 years old after influenza infection. Shock, GCS≤4 and high risk ANE-SS at PICU admission were risk factors for death in children with ANE. High-dose methylprednisolone may improve the prognosis of children with ANE.

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.
