This study aims to reveal the effect and mechanism of Gentianella turkestanorum total extract(GTI) in ameliorating non-alcoholic steatohepatitis(NASH). UPLC-Q-TOF-MS was employed to identify the chemical components in GTI. SwissTarget-Prediction, GeneCards, OMIM, and TTD were utilized to screen the targets of GTI components and NASH. The common targets shared by GTI components and NASH were filtered through the STRING database and Cytoscape 3.9.0 to identify core targets, followed by GO and KEGG enrichment analysis. AutoDock was used for molecular docking of key components with core targets. A mouse model of NASH was established with a methionine-choline-deficient high-fat diet. A 4-week drug intervention was conducted, during which mouse weight was monitored, and the liver-to-brain ratio was measured at the end. Hematoxylin-eosin staining, Sirius red staining, and oil red O staining were employed to observe the pathological changes in the liver tissue. The levels of various biomarkers, including aspartate aminotransferase(AST), alanine aminotransferase(ALT), hydroxyproline(HYP), total cholesterol(TC), triglycerides(TG), low-density lipoprotein cholesterol(LDL-C), high-density lipoprotein cholesterol(HDL-C), malondialdehyde(MDA), superoxide dismutase(SOD), and glutathione(GSH), in the serum and liver tissue were determined. RT-qPCR was conducted to measure the mRNA levels of interleukin 1β(IL-1β), interleukin 6(IL-6), tumor necrosis factor α(TNF-α), collagen type I α1 chain(COL1A1), and α-smooth muscle actin(α-SMA). Western blotting was conducted to determine the protein levels of IL-1β, IL-6, TNF-α, and potential drug targets identified through network pharmacology. UPLC-Q-TOF/MS identified 581 chemical components of GTI, and 534 targets of GTI and 1 157 targets of NASH were screened out. The topological analysis of the common targets shared by GTI and NASH identified core targets such as IL-1β, IL-6, protein kinase B(AKT), TNF, and peroxisome proliferator activated receptor gamma(PPARG). GO and KEGG analyses indicated that the ameliorating effect of GTI on NASH was related to inflammatory responses and the phosphoinositide 3-kinase(PI3K)/AKT pathway. The staining results demonstrated that GTI ameliorated hepatocyte vacuolation, swelling, ballooning, and lipid accumulation in NASH mice. Compared with the model group, high doses of GTI reduced the AST, ALT, HYP, TC, and TG levels(P<0.01) while increasing the HDL-C, SOD, and GSH levels(P<0.01). RT-qPCR results showed that GTI down-regulated the mRNA levels of IL-1β, IL-6, TNF-α, COL1A1, and α-SMA(P<0.01). Western blot results indicated that GTI down-regulated the protein levels of IL-1β, IL-6, TNF-α, phosphorylated PI3K(p-PI3K), phosphorylated AKT(p-AKT), phosphorylated inhibitor of nuclear factor kappa B alpha(p-IκBα), and nuclear factor kappa B(NF-κB)(P<0.01). In summary, GTI ameliorates inflammation, dyslipidemia, and oxidative stress associated with NASH by regulating the PI3K/AKT/NF-κB signaling pathway.

As a recognized rare and highly fatal disease, hereditary angioedema (HAE) is difficult to diagnose and characterized by recurrent edema involving the head, limbs, genitals and larynx, etc. Diagnosis of HAE is not difficult. However, low incidence and lack of clinical characteristics lead to difficulty of doctors on timely diagnosis and correct intervention for HAE patients. Therefore, it is crucial to improve the awareness of this disease and prevent its recurrence. for HAE patients. In view of absent cognition of doctors and the general public on HAE, patients often suffer from sudden death or become disabled due to laryngeal edema which cannot be treated in time. Thus, based on the Internet mobile terminal platform, the team set up an all-day rapid emergency response system which is provided for HAE patients by setting up "one-click help". The aim is to offer optimization on overall management of HAE and designed the intelligent follow-up management to provide timely assistance and specialized suggestion for patients with acute attacks.

Allergic diseases affect about 40% of the world's population. Environmental factors are important in the occurrence and development of allergic diseases. Dust mites are one of the most important allergens in the indoor environment. The World Health Organization proposes the "four-in-one, combination of prevention and treatment" treatment principle for allergic diseases, in which environmental control to avoid or reduce allergens is the first choice for treatment. Modern people spend much more time at home (including sleeping) than outdoors, and the control of the home environment is particularly critical. This practice introduces the hypoallergenic home visit program, which including home environment assessment, environmental and behavioral intervention guidance, and common household hypoallergenic supplies and service guidance for the patient's home environment. The real-time semi-quantitative testing of dust mite allergens, qualitative assessments of other indoor allergens, record of patients' household items and lifestyle, and precise, individualized patient prevention and control education will be conducted. The hypoallergenic home visit program improves the doctors' diagnosis and treatment data dimension, and becomes a patient management tool for doctors outside the hospital. It also helps patients continue to scientifically avoid allergens and irritants in the environment, effectively build a hypoallergenic home environment, reduce exposure to allergens in the home environment, and achieve the goal of combining the prevention and treatment of allergic diseases.

Objective: To analyze the clinical features of patients with acute pulmonary embolism (APE) living in high altitude area of Yunnan province. Methods: This was a cross-sectional retrospective study. APE patients, hospitalized in our hospital between January 2017 and December 2019, were included. The selected patients were divided into low-risk group, medium-risk group and high-risk group according to risk stratification. The clinical data of patients, including demographic data, the main symptoms, risk factors of APE, heart rate and systolic blood pressure and laboratory testing results (D-dimer, cardiac troponin I (cTNI), N terminal B-type natriuretic peptide (NT-proBNP)) and echocardiography and electrocardiogram examination results, were obtained through the electronic medical record system. The clinical characteristics of selected patients were analyzed. Results: A total of 392 patients, aged (63.5±15.7) years, 224 males (57.14%), were included in this study and there were 59 low-risk, 304 medium-risk and 29 high-risk patients in this cohort. The main clinical manifestations were chest pain (157(40.05%)), dyspnea (107(27.30%)), hemoptysis (55(14.03%)), syncope as the first symptom (20(5.10%)), and only 6 cases (1.53%) presented with the typical "Virchow's triad". Most of the patients were accompanied by atypical chest tightness (223(56.89%)) and cough (208(53.06%)). The main risk factors were venous thrombosis of lower limbs (179(45.66%)), hypertension (138(35.20%)), surgery (63(16.07%)), and chronic obstructive pulmonary disease (COPD) (62(15.82%)). There were 57 cases (14.54%) of coronary heart disease, 57 cases (14.54%) of diabetes, 51 cases (13.01%) of cerebral infarction, 47 cases (12.00%) of advanced age, 15 cases (3.83%) of tumor, 7 cases (1.79%) of activity restriction, 6 cases (1.53%) of pregnancy and 4 cases (1.02%) of hormone use in this cohort. The proportion of lower extremity venous thrombosis was significantly higher in low-risk group than in medium-risk group (P<0.01), COPD was more common in high-risk and medium-risk groups than in low-risk group (P<0.01), hypertension was more common in high-risk group than in medium-and low-risk groups (P<0.01). The proportion of advanced age was significantly higher in medium-risk group than in low-risk group (P<0.01). There were no significant differences in RBC and hemoglobin level between low-, medium-and high-risk groups (P>0.05). The level of D-dimer was significantly higher in high-risk group than in medium-and low-risk groups (P<0.05). Levels of NT-proBNP and cTNI were significantly higher in high-risk group than in medium- and low-risk groups (P<0.05). Increased proportion of cTNI and NT-proBNP was significantly higher in high-risk group than in medium- and low-risk groups (P<0.05). There were 105 (26.79%) patients with pulmonary hypertension (PAH). The incidence of PAH was significantly higher in high-risk group than in low-risk group (P<0.01). There were 104 patients (26.53%) with right ventricular enlargement, and the incidence of right ventricular enlargement was significantly higher in high-risk group than in medium-and low-risk groups (P<0.01). Characteristic changes of electrocardiogram in patient with APE were T-wave inversion of limb leads (98(25.00%)), followed by S_ⅠQ_ⅢT_Ⅲ (83(21.17%)). Conclusions: The main clinical manifestations of APE in Yunnan high altitude area are chest pain and dyspnea, and syncope is the first symptom in some patients, but the typical "Virchow's triad" is rare. The most common risk factors are lower extremity venous thrombosis, hypertension, and COPD. Clinical symptoms, risk factors and laboratory examination results differ among patients with different risk stratification.

ObjectiveTo improve the current standard of Belladonnae Herba in the 2020 edition of Chinese Pharmacopoeia. MethodTaking hyoscyamine sulfate， atropine sulfate and scopoletin as reference substances， and ethyl acetate-methanol-concentrated ammonia（17∶4∶2）as developing solvent， thin layer chromatography （TLC） was applied in the qualitative identification of Belladonnae Herba. The moisture， total ash and ethanol-soluble extract of Belladonnae Herba were determined based on the general principles in the 2020 edition of Chinese Pharmacopoeia （volume Ⅳ）. The contents of hyoscyamine sulfate and scopolamine hydrobromide were analyzed by high performance liquid chromatography （HPLC） with mobile phase of acetonitrile-54 mmol·L^-1 phosphate buffer solution （14∶86）， flow rate of 1.0 mL·min^-1 and detection wavelength at 210 nm. ResultThe spots in the TLC were clear with good separation and specificity. Hyoscyamine sulfate and scopolamine hydrobromide showed a good linearity with peak area in the range of 0.024 7-0.789 6 g·L^-1 （r=0.999 9） and 0.003 9-0.124 0 g·L^-1 （r=0.999 9）， the average recoveries of these two ingredients were 100.29% （RSD 1.6%） and 99.04% （RSD 1.4%）， respectively. The limits for moisture， total ash in Belladonnae Herba should be less than 13.0% and the limit for the ethanol-soluble extract should be more than 10.0%. Due to the low content and wide variation of scopolamine hydrobromide， the content of hyoscyamine sulfate should not be less than 0.098%. ConclusionThe established method is simple， specific and reproducible， which can be used to improve the quality control standard of Belladonnae Herba.
