ABSTRACT
By reviewing the materia medica， medical books and scripture history， combining modern and contemporary literature and field investigation， this paper systematically reviewed the name， origin， scientific name， producing area， quality， harvesting and processing of Scorpio in famous classical formulas to clarify the relationship between ancient and modern times and provide a reference basis for the development of related famous classical formulas. After the textual research， it can be seen that there are many names of Scorpio， and most of the materia medica use Xie or Quanxie as the official name. The origin of Scorpio used in the past dynasties is Buthus martensii， which is the same in ancient and modern times. B. martensii is mainly distributed in the central and eastern parts of China， as well as Mongolia， Korea and other places， located in East Asia. Therefore， pharmaceutical workers in China mostly continue to use the early Chinese name， that is， Dongya Qianxie， while modern Scorpiones taxonomists set its Chinese name as Mashi Zhengqianxie. In order to maintain the stability and continuity of the origin of Scorpio， the previous editions of Chinese Pharmacopoeia have always used the name of B. martensii. The geo-authentic producing area of Scorpio， which has been respected in the past dynasties， was Qingzhou， Shandong. Until the Republic of China， due to the different processing methods in the production area， the geo-authentic producing area expanded to Yu county， Henan， with Yu county as the distribution center， the best quality of Scorpio is produced by boiling in clear water and drying after boiling. The origin processing of Scorpio is mainly divided into clean water and salt water boiling and then drying， where the method of boiling with salt water was first described in Bencao Yuanshi， the purpose is antiseptic and suitable for storage， and the salt should be washed away when used clinically. There are few processing methods of Scorpio， in ancient times， it was used for roasting or frying after removing the feet， in modern times， it is mostly to remove impurities， wash and dry. Scorpio is not only used for medicinal purposes， but also has the habit of eating in many areas， so the consumption of resources is relatively large， and it is still mainly harvested from the wild， resulting in the decrease of wild resources year by year. Based on the research conclusion， it is recommended that B. martensii， which is produced in Qingzhou， Luyi or Yuzhou， should be used in the the development of famous classical formulas containing Scorpio， and the origin processing is preferable to be dried after boiling with water， and the processing specification should be selected as raw products. And B. martensii in geo-authentic producing areas was used as the seed source to establish a standardized breeding base to ensure the sustainable development of the resources of Scorpio.
ABSTRACT
Objective:To analyze the expression of glial fibrillary acidic protein (GFAP) and neuronal nuclei (NeuN) antigen in hippocampus based on the depression model of juvenile rats caused by chronic unpredictable stress (CUS), and to explore the effect of electroacupuncture vagus nerve on CUS depression model.Methods:Six juvenile SD rats were selected as the control group (without any stimulation), and the rest were divided into CUS group, pseudo stimulation group, fluoxetine group and electroacupuncture group by random number method after CUS modeling, with 6 rats in each group. Fluoxetine group was given 10 mg/kg fluoxetine intervention; control group and CUS group were given the same amount of normal saline intervention; In the electroacupuncture group, the distal vagus nerve was stimulated after ligation, while in the pseudo stimulation group, only vagus nerve was isolated without electrical stimulation. After 28 d of intervention, the five groups were subjected to Open-field Test and Sucrose Preference Test. Hippocampal neurons were detected by hematoxylin and eosin (HE) staining, and the expressions of GFAP and NeuN in hippocampal were detected by immunohistochemistry.Results:After CUS modeling and before intervention, the number of vertical and horizontal movements, sucrose consumption and sucrose preference in CUS group, pseudo stimulation group, fluoxetine group and electroacupuncture group were significantly lower than those in the control group (all P<0.01); After the intervention, the above indexes in CUS group and pseudo stimulation group were still lower than those in the control group (all P<0.01), but the above indexes in fluoxetine group and electroacupuncture group were significantly higher than those in CUS group and pseudo stimulation group (all P<0.01). HE staining showed that the arrangement of hippocampal neurons in CUS group and pseudo stimulation group were loose, and there were cell swelling and pyknosis, which was significantly improved in fluoxetine group and electroacupuncture group. Immunohistochemical results showed that compared with the control group, the expression of GFAP increased and NeuN decreased in the hippocampus of CUS group and pseudo stimulation group (all P<0.01); Compared with CUS group and pseudo stimulation group, the expression of GFAP decreased and NeuN increased in fluoxetine group and electroacupuncture group (all P<0.01). Conclusions:Electroacupuncture of vagus nerve can obviously improve the depression symptoms of juvenile rats, which is similar to fluoxetine, and may be related to regulating the expression of GFAP and Neun in hippocampus.
ABSTRACT
Objective:To analyze and compare the clinical indicators and the liver failure-related prognostic score of patients with amanita phalloides poisoning with different prognoses, and to explore potential prognostic indicators.Methods:A retrospective case-control study was conducted. The clinical data of 52 patients with amanita phalloides poisoning admitted to the department of emergency of Xijing Hospital Affiliated to Air Force Medical University from September 2016 to September 2021 were collected, including general information (gender, age), clinical indicators at admission [mean arterial pressure (MAP), total bilirubin (TBil), aspartate transaminase (AST), alanine transaminase (ALT), albumin (ALB), serum creatinine (SCr), blood urea nitrogen (BUN), creatine kinase (CK), D-dimer, fibrinogen degradation product (FDP), prothrombin time (PT), activated partial thromboplastin time (APTT), prothrombin activity (PTA), international normalized ratio (INR), white blood cell count (WBC), platelet count (PLT)], liver failure-related prognostic score [sequential organ failure assessment (SOFA), chronic liver failure (CLIF)-SOFA score, European Foundation for the Study of Chronic Liver Failure-organ failure (CLIF-C OF)], and 28-day outcome. The clinical indicators and liver failure-related prognostic scores of the patients with different prognoses were compared. Receiver operator characteristic curve (ROC curve) was used to determine the prognostic value of statistically significant indicators between different prognosis of patients with amanita poisoning.Results:A total of 45 patients were enrolled, of which 38 survived and 7 died within 28 days. The coagulation indicators including PT, APTT, INR, and liver failure-related prognostic scores including SOFA score, CLIF-SOFA score, and CLIF-C OF score in the patients of death group were significantly higher than those in the survival group [PT (s): 69.59±15.94 vs. 25.99±4.64, APTT (s): 83.44±17.82 vs. 42.64±3.79, INR: 6.13±1.47 vs. 2.07±0.33, SOFA score: 11.57±1.38 vs. 6.03±0.77, CLIF-SOFA score: 9.86±2.17 vs. 5.55±0.67, CLIF-C OF score: 11.71±0.97 vs. 8.37±0.35], and PLT was significantly lowered (×10 9/L: 80.57±29.65 vs. 169.60±11.80, all P < 0.05). ROC curves showed that coagulation indicators including PT, APTT, INR, PLT, and liver failure-related prognostic scores including SOFA score and CLIF-C OF score were associated with the prognosis of patients with amanita phalloides poisoning, with the area under the ROC curve (AUC) of > 0.75. The sensitivity of the clinical indicators was above 85%, and the AUC and specificity of INR were the highest, which were 0.88 [95% confidence interval (95% CI) was 0.74-1.00] and 83.0%, respectively; meanwhile, the sensitivity of the liver failure-related prognostic scores was 100%, and the AUC and specificity of the CLIF-C OF score were the highest, which were 0.86 (95% CI was 0.74-0.99) and 66.0%, respectively. Conclusion:INR and CLIF-C OF score can be used to evaluate the poor prognosis of patients with amanita phalloides poisoning.
ABSTRACT
Isatis indigotica Fort. (Ban-Lan-Gen) is an herbal medicine prescribed for influenza treatment. However, its active components and mode of action remain mostly unknown. In the present study, erucic acid was isolated from Isatis indigotica Fort., and subsequently its underlying mechanism against influenza A virus (IAV) infection was investigated in vitro and in vivo. Our results demonstrated that erucic acid exhibited broad-spectrum antiviral activity against IAV resulting from reduction of viral polymerase transcription activity. Erucic acid was found to exert inhibitory effects on IAV or viral (v) RNA-induced pro-inflam-matory mediators as well as interferons (IFNs). The molecular mechanism by which erucic acid with antiviral and anti-inflammatory properties was attributed to inactivation of NF-kB and p38 MAPK signaling. Furthermore, the NF-kB and p38 MAPK inhibitory effect of erucic acid led to diminishing the transcriptional activity of interferon-stimulated gene factor 3 (ISGF-3), and thereby reducing IAV-triggered pro-inflammatory response amplification in IFN-β-sensitized cells. Additionally, IAV- or vRNA-triggered apoptosis of alveolar epithelial A549 cells was prevented by erucic acid. In vivo, erucic acid administration consistently displayed decreased lung viral load and viral antigens expression. Meanwhile, erucic acid markedly reduced CD8+cytotoxic T lymphocyte (CTL) recruitment, pro-apoptotic signaling, hyperactivity of multiple signaling pathways, and exacerbated immune inflammation in the lung, which resulted in decreased lung injury and mortality in mice with a mouse-adapted A/FM/1/47-MA(H1N1) strain infection. Our findings provided a mechanistic basis for the action of erucic acid against IAV-mediated inflammation and injury, suggesting that erucic acid may have a therapeutic potential in the treatment of influenza.
ABSTRACT
OBJECTIVE:To provide reference for better improving the risk perception of Omeprazole sodium for injection in nurses in a third-grade class-A hospital,strengthening risk management of ward drugs and ensuring safety of patients. METHODS:Nurses in the clinical departments in a third-grade class-A hospital where usage frequency of Omeprazole sodium for injection was relatively more were adopted as study subjects and a self-designed questionnaire was used to investigate on related knowledge on medication risk in nurses in emergency department,gastroenterology department,ICU and CCU in 2012 and 2014. RESULTS:51 and 81 questionnaires were distributed in 2012 and 2014,and 51 and 81 were effectively received with effective recovery of 100%and 100%,respectively. In both surveys,100% surveyed nurses could correctly choose one solvent at least,1.96% and 3.70%nurses could correctly choose 2 solvents;correct answering rates of intravenous administration time were 94.12% and 96.30%,re-spectively;correct answering rates of stable duration after preparation were both lower than 9%;correct answering rates of adverse reaction of this drug were 3.92% and 1.23%,respectively;correct answering rates of interaction of this drug were 1.96% and 6.17%,respectively;correct answering rates of stable formulation of this drug were 17.65%and 22.22%,respectively;the propor-tion of nurses observing ADRs were 25.49% and 13.58%,respectively;the proportion of nurses finding inappropriate compatibility were 15.69% and 22.22%,respectively,Ornidazole and sodium chloride injection was the most used incompatible drug;45% or more nurses hoping to strengthen the continuing education of nursing personnel. CONCLUSIONS:Nurses in this third-grade class-A hospital lack certain knowledge on the medication risk of Omeprazole sodium for injection,the drug risk management is not sufficient,and awareness prevention of drug risk is relative weak. It is suggested that the hospital should strengthen drug risk management system,nurses should strengthen the learning about drug risk and play the role of clinical pharmacists in the drug risk management to reduce the related drug risk and incidence of adverse reactions.
ABSTRACT
Objective To evaluate the effects of multiple exposures to sevoflurane anesthesia on the expression of apolipoprotein E (ApoE) in the hippocampus of neonatal rats.Methods Twenty-four pathogen-free Sprague-Dawley rats (12 males,12 females),aged 7 days,weighing 15-20 g,were randomly divided into 2 groups (n=12 each) using a random number table:control group (group Con) and multiple exposures to sevoflurane anesthesia group (group Sev).On postnatal day 7,14 and 21,2.6％ sevoflurane was inhaled for 2 h in group Sev,while the mixed gas of oxygen and air was inhaled instead of sevoflurane in group Con.Morris water maze test was carried out on postnatal day 31-37 to assess cognitive function.The rats were then sacrificed,and the hippocampus was removed to determine the expression of ApoE protein in hippocampal CA1,CA3 and DG regions (by immunohistochemistry) and the expression of ApoE mRNA (by fluorescent quantitative real-time reverse transcriptase polymerase chain reaction).Results There was no significant difference between the two groups in cognitive function (P＞0.05).Compared with group Con,the expression of ApoE protein in hippocampal CA1 and CA3 regions and ApoE mRNA was significantly up-regulated in group Sev (P＜0.05),and no statistically significant change was found in the expression of ApoE protein in hippocampal DG region in group Sev (P＞0.05).Conclusion Multipie exposures to sevoflurane anesthesia can up-regulate the expression of hippocampal ApoE and produce mild neurotoxicity without causing changes in cognitive function in neonatal rats.

ABSTRACT
AIM To study the protective effect of Gn-3 (a stilbene polymer isolated from Gnetum parvifolium) against liver injury induced by CCl4, N-acetyl-p-aminophenol (APAP) and Bacillus Calmette-Guerin (BCG) plus bacterial lipopolysaccharide (LPS) in mice. METHODS The experimental model of liver injury were induced by 0.1% CCl4 ip (10 mL*kg-1*d-1 for 3d), APAP ip (150 mg*kg-1) or BCG (5 mg) plus LPS (7.5 μg) in mice. The levels of ALT in serum, MDA and GSH in liver tissues were detected. The histopathologic changes were observed by light microscope. RESULTS Gn-3 was shown to markedly reduce the elevated serum ALT levels, liver tissue MDA and improve the histopathological changes in all the three experimental liver injury models. No effect of Gn-3 was observed on the liver GSH level in liver injury mice. CONCLUSION Gn-3 was found to inhibit the development of liver injury caused by CCl4, APAP, or BCG plus LPS. This means that Gn-3 has liver protective effects.
ABSTRACT
Hepatic carcinomas were induced with the administration of diethyl-nitrosamine (DEN) in rats. The morphological changes of the liver tissues in the course of carcinogenesis could be divided into 3 successive stages: the nonspecific changes reacting to the drug toxicity, non-cancerous hyperplastic nodules of hepatocytes and ductular cystadenomatous lesions,and the lesions of genuine malignancy including hepatocellular carcinoma and cholangiocarcinoma.The ultrastructural alterations of hepatocellular carcinoma showed a complicate picture and were related to the differentiation of the tumor cells. In one case of cholangiocarcinoma, numerous cytoplasmic dense-core granules similar to the neurosecretary granules seen in apudoma were found in some of the tumor cells, which is postulated to be a special type of cholangiocarcinoma. On the basis of the results, Ihe histogenesis of the neoplasms after DEN administration is considered to originate from hyperplastic nodules of hepatic cells and ductular hyperplasia.
