ObjectiveThis paper aims to systematically collect and organize ancient and modern clauses and studies containing Xieqingwan， excavate and analyze the key information of Xieqingwan， and provide a reference for facilitating the development of the classic formula Xieqingwan. MethodsThe composition， dosage， decocting methods， usage， and other key information of Xieqingwan in ancient traditional Chinese medicine books were collected and analyzed by means of literature research and metrological methods. The modern clinical application of Xieqingwan was summarized. ResultsA total of 42 pieces of effective data involving 32 ancient traditional Chinese medicine books were collected. Xieqingwan was first recorded in Xiaoer Yaozheng Zhijue. The drug origin of this formula is basically clear in the ancient traditional Chinese medicine books. The modern drug usage and decocting method were as follows： Angelicae Sinensis Radix， Gentianae Radix et Rhizoma， Chuanxiong Rhizoma， Gardenia seeds， Radix et Rhizoma Rhei， Notopterygii Rhizoma et Radix， and Saposhnikoviae Radix were grounded to fine powder， decocted with honey， and finally formed into pills with the size of a chicken head （1.5 g）. It was suggested that half a pill or one pill were taken for one dose with warm Lophatheri decoction and sugar. The indications and clinical application had developed from the recordings in Xiaoer Yaozheng Zhijue and evolved from pediatrics to ophthalmic otolaryngology， neurology， dermatology， digestion， and respiratory diseases. The main pathogenesis of these diseases is heat in the liver meridian and is treated. The effect of Xieqingwan is "clearing away heat and toxicity， removing fire and relaxing the bowels， and dispersing swelling and relieving pain". It is recommended to use the corresponding preparation methods in the 2020 Edition of Pharmacopoeia of the People's Republic of China. Modern clinical studies are centered around the clinical application of Xieqingwan， which is often modified and used in treating Tourette syndrome， herpes， febrile convulsion， sleepwalking， and insomnia. ConclusionThis paper conducts a thorough textual research of the key information of Xieqingwan， induces its historic evolution， and confirms its key information， so as to provide a reference for the future development of Xieqingwan.

Objective:To establish a 14-day prognosis model for emergency patients with acute ischemic cerebral stroke and evaluate its predictive efficacy.Methods:A prospective cohort study was conducted. Patients with acute ischemic stroke admitted to the emergency department of Beijing Bo’ai Hospital within 72 hours of onset from October 2018 to December 2020 were enrolled. Univariate and multivariate logistic regression analysis were used to screen the risk factors of poor prognosis. The ROC curve was drawn to determine the cut-off value of continuous variables and discretise data with reference to clinical practice. The corresponding scores were set up according to the β regression coefficient of each variable, and the clinical scale prediction model of short-term prognosis of acute cerebral infarction was established. Patients with ischemic stroke in the hospital from January to December 2021 were selected as the internal validation, to verify the constructed predictive model.Results:A total of 321 patients were included in the study, including 223 in the training set and 98 in the internal validation set. Multivariate logistic regression analysis showed that age, hypersensitive C-reactive protein, prealbumin (PA), infarct volume, Frailty Screening Questionnaire (FSQ) and National Institute of Health Stroke Scale (NIHSS) were independent risk factors for poor short-term prognosis of acute cerebral infarction. The total score of the clinical prediction scoring system for short-term prognosis of acute cerebral infarction in the emergency department was 15 points, including age ≥74 years (1 point), PA ≤373 mg/L (2 points), large artery atherosclerosis (1 point), cardiogenic embolism (2 points), infarct volume ≥ 2.18 cm 3 (2 points), FSQ ≥3 points (1 point), NIHSS ≥4 points (6 points); The area under the ROC curve (AUC) of the scoring system for predicting short-term poor prognosis of acute cerebral infarction was 0.927 (95% CI: 0.894-0.960). The optimal cut-off value was ≥5 points, and the sensitivity and specificity were 0.770 and 0.976, respectively. In the internal validation set, the scoring system had similar predictive value for poor outcomes (AUC=0.892, 95% CI:0.827-0.957). Conclusion:The scoring system for short-term prognosis prediction of acute ischemic cerebral infarction has good diagnostic efficacy, and could guide clinicians to judge the prognosis of emergency patients in the early stage.

BACKGROUND:Low to moderate intensity aerobic exercise can help protect knee cartilage.Long-chain non-coding RNAs are crucial for gene regulation.Among them,HOTAIR can activate numerous transcriptional co-repressors to repress the activation of certain genes. OBJECTIVE:To detect the expression levels of HOX transcript antisense RNA(HOTAIR)and other related factors in chondrocytes of high fat-fed mice and after low to moderate intensity exercise intervention,and to investigate their role in cartilage injury and sports rehabilitation. METHODS:Thirty C57BL/6 male mice were randomly divided into control group(normal feeding),high fat feeding group and high fat feeding plus treadmill exercise group,with 10 mice in each group.The mice in the high fat feeding plus treadmill exercise group were subjected to an 8-week low to middle intensity treadmill exercise,and the mice in the other two groups were caged.During this period,body mass was weighed every week on Sunday.After the 8-week exercise,both lower extremities of mice were taken,and the knee joint was scanned using Micro CT to make a 3D femoral condyle image to obtain relevant parameters.Hematoxylin-eosin and safranin O-fast green staining of the knee joint were performed for Mankin and Osteoarthritis Research Society International(OARSI)scoring.RT-PCR was performed to detect the mRNA levels of cartilage metabolic indicators and lipid metabolism indicators,including type II collagen,matrix metalloproteinase 13,interleukin 1,low-density lipoprotein receptor-related protein 5,HOTAIR and its downstream factor lysine specific demethylase 1. RESULTS AND CONCLUSION:The body mass of high fat-fed mice were higher than that of the control group(P<0.01),and the body mass of the high fat feeding plus treadmill exercise group was lower than that of the high fat feeding group(P<0.05).The connectivity density of high fat-fed mice was higher than that of the control group(P<0.01).Mankin and OARSI scores of the high fat feeding were higher than those of the control group(P<0.01)and high fat feeding plus treadmill exercise group(P<0.05).The mRNA level of type II collagen was higher in the control group than the high fat feeding plus treadmill exercise group(P<0.05)and high fat feeding group(P<0.01)as well as higher in the high fat feeding plus treadmill exercise group than the high fat feeding group(P<0.01).The mRNA levels of matrix metalloproteinase 13,interleukin 1,low-density lipoprotein receptor-related protein 5,HOTAIR and lysine specific demethylase 1 were higher in the high fat feed group than the control group and high fat feeding plus treadmill exercise group(P<0.01).To conclude,high fat feeding can increase the bone substance of the femoral condyle,lead to knee cartilage wear,and cause chondrocyte metabolism disorder.HOTAIR is highly expressed in this process.An 8-week low to middle intensity treadmill exercise can reduce body mass,alleviate knee cartilage wear,improve chondrocyte function and down-regulate HOTAIR expression in mice.

To reduce the subjectivity and uncertainty present in the current international methods of drug value pricing when converting value into monetary prices,based on the hedonic pricing theory,it considers the post-negotiation price between manufacturers and payers as a reasonable price reference in the value pricing of Chinese patent medicine.By constructing an indicator system for the characteristics of Chinese patent medicine,it selects and measures the value characteristic variables that affect the price of Chinese patent medicine.It serves as the theoretical foundation and research basis for establishing a Hedonic price model between characteristic price variables and negotiation prices,thereby promoting the enhancement of rationality and objectivity in value-guided pricing of Chinese patent medicine.
