Gastrodin is a phenolic glycoside that has been demonstrated to provide neuroprotection in preclinical models of central nervous system disease, but its effect in subarachnoid hemorrhage (SAH) remains unclear. In this study, we showed that intraperitoneal administration of gastrodin (100 mg/kg per day) significantly attenuated the SAH-induced neurological deficit, brain edema, and increased blood-brain barrier permeability in rats. Meanwhile, gastrodin treatment significantly reduced the SAH-induced elevation of glutamate concentration in the cerebrospinal fluid and the intracellular Ca overload. Moreover, gastrodin suppressed the SAH-induced microglial activation, astrocyte activation, and neuronal apoptosis. Mechanistically, gastrodin significantly reduced the oxidative stress and inflammatory response, up-regulated the expression of nuclear factor erythroid 2-related factor 2, heme oxygenase-1, phospho-Akt and B-cell lymphoma 2, and down-regulated the expression of BCL2-associated X protein and cleaved caspase-3. Our results suggested that the administration of gastrodin provides neuroprotection against early brain injury after experimental SAH.

Objective: To investigate the therapeutic effect of creatine phosphate sodium (CP, Neoton) at early stage of myocardium diastolic dysfunction. Methods: A total of 138 cases with myocardium diastolic dysfunction were divided into CP group (n=109) and routine treatment group (n=29). All the patients received routine treatment. The CP group received CP treatment based on routine treatment(CP 2g+5%glucose or 0.9% sodium chloride 100ml, iv. drip, for patients with mild diastolic dysfunction was 1time/d, patients with moderate diastolic dysfunction was 2 times/d), duration was 7~14 days. Color-coded Doppler echocardiography was used to detect transmitral peak early diastolic velocity (E-wave)，transmitral peak late diastolic velocity (A-wave)，peak early diastolic velocity of mitral annulus (Ea), and peak late diastolic velocity of mitral annulus(Aa), and the value of E/A ,Ea/Aa and E/Ea were calculated. Symptoms, signs and items from echocardiography were compared between the two groups before and after treatment. Results: After treatment, all symptoms and signs of patients in two groups significantly improved (P<0.05~0.01), and the marked effective rate in CP group was significantly higher than that of routine treatment group (96.2% vs. 57.1%, P<0.01). In CP group, the marked effective rate of E/A (81.65% vs. 10.34%), Ea/Aa (83.49% vs. 13.79%) and E/Ea (92.86% vs. 12.00%) were significantly higher than those in routine treatment group (P<0.01all). Conclusion: Creatine phosphate possesses marked effect for improve patient’s condition and diastolic dysfunction.

PURPOSE: Parkinson's disease (PD) is a common age-dependent neurodegenerative disease. MiR-212 has been demonstrated to exert protective effects in several neurological disorders. The present study aimed to investigate the role and underlying molecular mechanism of miR-212 in PD. MATERIALS AND METHODS: 1-methyl-4-phenylpyridinium (MPP+)-induced SH-SY5Y cells were applied as a PD model in vitro. RTqPCR was used to measure the expression of miR-212 and Kruppel-like factor 4 (KLF4) mRNA. Western blot analysis was performed to detect the protein levels of KLF4, Notch1 and Jagged1. Cell viability and apoptosis were determined by the Cell Counting Kit-8 and flow cytometry, respectively. Quantitative analysis of caspase-3 activity, lactate dehydrogenase (LDH), reactive oxygen species (ROS), superoxide dismutase (SOD), tumor necrosis factor-α (TNF-α), and interleukin-1 beta (IL-1β) was conducted with corresponding ELISA kits. Dual-luciferase reporter assay was employed to evaluate the relationship between miR-212 and KLF4. RESULTS: MiR-212 was downregulated in MPP+-induced SH-SY5Y cells. Also, miR-212 alleviated MPP+-induced SH-SY5Y cell damage, embodied by increased cell viability, decreased caspase-3 activity, LDH release, ROS production, TNF-α, and IL-1β expression, as well as elevated SOD levels. KLF4 was a direct target of miR-212, and miR-212 repressed KLF4 expression in a post-transcriptional manner. Moreover, miR-212-mediated protection effects were abated following KLF4 expression restoration in MPP+-induced SH-SY5Y cells, represented as lowered cell viability and enhanced apoptotic rate. Furthermore, Notch signaling was involved in the regulation of miR-212/KLF4 axis in MPP+-induced SH-SY5Y cells. CONCLUSION: miR-212 might attenuate MPP+-induced neuronal damage by regulating KLF4/Notch signaling pathway in SH-SY5Y cells, a promising target for PD therapy.

Objective To explore the clinical characteristics of human bocavirus (HBoV) infection in the children with severe lower respiratory tract infection.Methods The clinical data of the hospitalized children with sputum HBoV-positive were analyzed retrospectively,who were hospitalized at the Pediatric Intensive Care Unit of Children's Hospital Affiliated to Capital Institute of Pediatrics from September 1,2016 to March 31,2017.Results A total of 17 children were included in the study.The ratio of male to female was 15 ∶ 2.The diagnostic age ranged from 4 months to 4 years and 10 months old.82.4％ (14/17 cases) of the patients were infants less than 2 years old.Autumn and winter were high-occurrence seasons.Pediatric Critical Illness Scores(PCIS) were 68-88 scores(median 82 scores).PCIS was less than 70 scores in 1 case,and between 70 scores and 80 scores in 7 cases,and more than 80 scores in 9 cases.The main clinical manifestations were respiratory system involvement,including dyspnea in 17 cases (100％),fever in 14 cases (82.4％),cough in 16 cases (94.1％),wheezing in 13 cases (76.5％),and moist rales in 13 cases (76.5％).The main abnormal chest radiological findings showed patchy shadows in 7 cases (41.2％) and consolidation in 6 cases (35.3％).The oxygenation index was 73.9-296.0 mmHg(1 mmHg =0.133 kPa),and median was 176 mmHg.The oxygenation index was between 100-200 mmHg in 7 cases(41.2％),and less than 100 mmHg in 2 cases(11.7％).Type Ⅰ respiratory failure occurred in 11 cases (64.7％),while type Ⅱ respiratory failure occurred in 6 cases (35.3 ％).All of the patients need respiratory support with mechanical ventilation.Among them,6 patients (35.3％) were treated by non-invasive ventilation and their ventilation time were 25-128 h(median 65 h),while 11 patients (64.7％) were treated by invasive ventilation and their ventilation time was 42-178 h(median 70 h).Other organ or system dysfunction is mild.The length of hospital stay ranged from 3 days to 13 days.The cure rate was 100％.Conclusions HBoV infection in the children with severe lower respiratory tract infection is common in infants under 2 years old,with acute onset and rapid recovery.The obvious clinical symptoms are fever,cough,wheezing and dyspnea.Although respiratory failure is common,other organ or system dysfunction is mild,which may bring about a good prognosis.

Objective:To analyze the epidemiological features of respiratory syncytial virus (RSV) infection in Beijing, and monitor the sequence variations in RSV glycoprotein (G) gene and clinical features of infected children.Methods:Respiratory tract specimens were collected from children with acute respiratory infection in the Children′s Hospital Affiliated to Capital Institute of Pediatrics from January 1, 2023 to December 31, 2023. RSV-positive specimens screened by multiple nucleic acid testing were subjected to PCR to amplify the full-length RSV G gene. A phylogenetic tree was constructed after gene sequencing to analyze RSV subtypes and trace G gene variants. Clinical data were retrieved from the medical record system to analyze the clinical features of children with RSV infection in Beijing.Results:A total of 5 489 respiratory specimens were collected from 3 046 male patients and 2 443 female patients. The average age of the patients was 4.36 years. A total of 589 RSV-positive specimens (10.7%, 589/5 489) were detected with 349 from male patients and 240 from female patients. The average age of children with RSV infection was (2.51±2.78) years and the median age was 0.48 years. RSV had been circulating among children in Beijing since March 2023 with two epidemic peaks in May (24.6%, 122/496) and December (18.2%, 126/693). The predominant subtype of RSV in the first half of 2023 was subtype A, but it was replaced by subtype B from November 2023. Phylogenetic analysis revealed a novel G gene of RSV subtype B (RSV-B-BA9-954bp) with a length of 954 bp, which belonged to a new cluster in the phylogenetic tree. The percentage of patients admitted to the Intensive Care Unit (ICU) was higher in children with new variant of RSV subtype B infection than in those with common RSV subtype B infection [44.1% (15/34) vs 25.2% (31/123), χ 2=4.600, P=0.032], while the counts of white blood cells and the levels of C-reactive protein were lower in the children with new variant infection ( P<0.05). Conclusions:RSV has been prevalent among children in Beijing since March 2023 with two epidemic peaks. The predominant A subtype is gradually replaced by to B subtype. A new variant of RSV B G gene (RSV-B-BA9-954bp) is detected among the children.
