[Regulatory effect of Shudihuang on expressions of BDNF/TrkB and NRG-3 in prefrontal cortex and striatum of ADHD model rats]
Zhongguo Zhong Yao Za Zhi 2018 Sep;43(17):3539-3544.PMID:30347924DOI:10.19540/j.cnki.cjcmm.20180522.004.
To observe the effect of Shudihuang on behaviors and expression of BDNF/TrkB and NRG-3 in prefrontal cortex and striatum of attention deficit hyperactivity disorder (ADHD) model rats. Thirty 4-week-old spontaneous hypertension rats (SHR) were randomly divided into model group, methylphenidate hydrochloride (MPH, 2 mg·kg⁻¹·d⁻¹) and Shudihuang group (2.4 g·kg⁻¹·d⁻¹). Another 10 Wistar-Kyoto (WKY) rats were selected as normal control group. The 0.5% CMC-Na solution was administered to model group and WKY rats (2 mL·kg⁻¹·d⁻¹). All of the rats were treated for 4 weeks. The open field test was performed at the 14th and 28th days after gavage, in order to evaluate the spontaneous and impulsive behaviors. Subsequently, gene and protein expressions of BDNF/TrkB and NRG-3 were tested by RT-qPCR and Western blot. Compared with model group, MPH and Shudihuang groups showed significant reduction in total distance, mean velocity and central distance in the open field test (P<0.05), and Shudihuang group displayed a shorter central distance than MPH group (P<0.05). RT-qPCR and Western blot analysis indicated that expressions of BDNF/TrkB and NRG-3 were lower in prefrontal cortex and striatum of SHR compared with WKY rats. Four weeks later after administration, both Shudihuang and MPH significantly elevated mRNA and protein expressions of BDNF/TrkB and NRG-3 (P<0.05).In conclusion, neurodevelopmental disorder mediated by BDNF/TrkB and NRG-3 was closely related with SHR rats' behaviors. Shudihuang may ameliorate the spontaneous and impulsive behaviors by up-regulating the expressions of BDNF/TrkB and NRG-3 and improving growth and maturation of neurons in SHR.
Synthetic cannabinoid "Black Mamba" infidelity in patients presenting for emergency stabilization in Colorado: a P SCAN Cohort
Clin Toxicol (Phila) 2018 Mar;56(3):193-198.PMID:28862050DOI:10.1080/15563650.2017.1357826.
Background: Use of new psychoactive substances (NPS) has increased over the last decade. During this period, variability of both clinical presentations and chemical compositions of these compounds has increased. Synthetic cannabinoids (SCs) are the most commonly used NPS and there are more than 100 documented unique molecules in this class. "Black Mamba", often associated to ADB-FUBINACA, is the most commonly used SC in Colorado. It has been linked to kidney injury, myocardial toxicity, seizures, and death. Objectives: We aim to identify the chemical constituents and quantification of eight cases of reported "Black Mamba" use in order to further understand the clinical variability in patients presenting for emergency stabilization. Methods: We report data from eight cases of reported "Black Mamba" use prospectively captured through the Colorado site of the Psychoactive Surveilance Consortium and Analysis Network (P SCAN). P SCAN is a geographically representative group of academic hospitals that capture clinical presentation, outcome, and biologic samples from patients that present for emergency stabilization following NPS use. Serum and urine samples were analyzed and quantified by liquid chromatography-quadrupole time-of-flight mass spectrometry after a qualitative screen for over 600 unique NPS compounds. Results: In the reported eight cases, the median age was 28 years old. There were four male and four females. Four patients had agitation/delirium and four patients had chest pain. Normal saline, benzodiazepines and ondansetron were the common treatment provided in the emergency department (ED). Two patients were discharged from the ED and six patients being admitted for emergency observation with a median length of stay (LOS) of six hours. No deaths were reported. Confirmatory testing revealed that only five patients (62.5%) had SCs found in blood or urine samples. Cocaine, NRG-3, 3-methoxyphencyclidine hydrochloride (MeO-PCP), and methamfetamine were identified in other presentations. Conclusions: The wide range of clinical presentations from "Black Mamba" use may be explained by the wide variability of chemical constituents found by laboratory analysis.
