Qingzao Jiufeitang is a famous classical formula for treating lung injury caused by warm and dryness， included in the Catalogue of Ancient Famous Classical Formulas（The First Batch）. By systematically organizing ancient and modern literature on this formula， this study analyzed and verified the origin， medicinal composition， original plants and processing， dosage and decoction method， efficacy and application of this formula. According to the research， Qingzao Jiufeitang was first recorded in Yimen Falyu in the Qing dynasty， and its creation was mainly inspired by the Ming dynasty physician MIAO Xiyong's idea of the moisturizing drugs with sweet flavour and cold nature. Based on the 2020 edition of the Pharmacopoeia of the People's Republic of China（hereinafter referred to as the Chinese Pharmacopoeia） and the textual research results of modern scholars on traditional Chinese herbal medicines， the botanical sources and processing methods of the herbs in this formula are basically clarified. Among them， Mori Folium， Gypsum Fibrosum， Ginseng Radix et Rhizoma， Sesami Semen Nigrum， Asini Corii Colla， Ophiopogonis Radix and Eriobotryae Folium are consistent with the 2020 edition of the Chinese Pharmacopoeia. The primary source of Glycyrrhizae Radix et Rhizoma is the dried roots and rhizomes of Glycyrrhiza uralensis， family Leguminosae， while the primary source of Armeniacae Semen Amarum is the dried mature seeds of Prunus armeniaca， family Rosaceae. It is recommended to use Gypsum Ustum， stir-fried Sesami Semen Nigrum， stir-fried Armeniacae Semen Amarum， Asini Corii Colla bead， and honey-fried Eriobotryae Folium， and the rest of the raw products. According to the conversion of ancient and modern doses， the recommended dosages are 11.19 g for Mori Folium， 9.33 g for Gypsum Fibrosum， 3.73 g for Glycyrrhizae Radix et Rhizoma， 2.61 g for Ginseng Radix et Rhizoma， 3.73 g for Sesami Semen Nigrum， 4.48 g for Ophiopogonis Radix， 2.61 g for Armeniacae Semen Amarum， 3.73 g for Eriobotryae Folium. The decoction method is to add 300 mL of water， decoct it down to 180 mL， remove the residue， and then add 2.98 g of Asini Corii Colla into the decoction. Take it warm after meals， two to three times a day. Qingzao Jiufeitang has the effects of clearing dryness and moistening the lungs， nourishing Yin and invigorating Qi. In ancient times， it was mainly used to treat stagnation and depression of various Qi， as well as paralysis， asthma and vomiting. In modern clinical practice， it is mostly used to treat diseases in respiratory system， otolaryngology， skin system and digestive system caused by warm-dry impairing lung， deficiency of both Qi and Yin. The above research results can provide a reference for the later development of Qingzao Jiufeitang.

The effect of realgar nanoparticles (NPs) on endogenous small molecules in rat kidney was analyzed by mass spectrometry-based metabolomics.The relationship between the changes of metabolites and the nephrotoxicity of realgar NPs was also discussed to provide a basis for the further toxicity study and the clinical application of realgar NPs.SD rats were randomly divided into seven groups,including control group,three doses (40,200,1 000 mg/kg) of relegar and realgar NPs groups,respectly.After 28 days of continuous intragastric administration,all rats were sacrificed and their serum and kidney samples were collected.The toxic effect of realgar NPs on kidney tissues were examined by biochemical analysis and histopathologic examination,which revealed a dosedependent nephrotoxicity induced by realgar NPs.The LC-MS and GC-MS analysis were performed for the subsequent metabolomics study.A series of 32 metabolites were found to be altered significandy in the kindey of realgar NPs treated rats,and might serve as potential nephrotoxicity biomarkers.The results of metabolic pathway analysis indicated that the nephrotoxicity of realgar NPs might be associated with the disorders of the amino acids and phosphatidic acid metabolism.

Objective: The purpose of this study was to determine the relationship between TCM pattern and Hp infection and apoptosis of stomach mucosa in chronic gastritis, to discover the substance of TCM Pattern of chronic gasuitis on genetic molecular level and to establish syndrome differentiation system of chronic superficial gastritis on molecular level Methods: Get gastric mucosa tissue by electronic gastroscope. Hp infection, expression of Fas and bel-2 of 41 cases of incoordination between the liver and stomach group (IBLS group) and 50 cases of Dampness-beat in spleen and stomach(DHSS group) of chronic superficial gastritis were investigated by immunohistocbemistry examination, with 10 healthy persons as control group. Muti-factor non-condition logistic regression analysis was adopted to analyze the data. Results: The positive rate of HP was of 22%, 52% and 10% respectively in the IBLS group, the DHSS group and the control group. The positive rate of HP in the DHSS group was significant higher than in the IBLS and control group, showing there is a significant correlation between DHSS patern and HP infection. The expression rate of bcl-2 antigen was 24.2%, 76.0% and 30.0% respectively in the IBLS, DHSS and control group. The expression rate of bcl-2 antigen in the DHSS group was significant higher than in and the IBLS and control group(P＜0.01), showing there was significant correlation between DHSS pattern and expression rate of bcl-2 antigen(P＜0.01). The expression rate of Fas antigen was 70.7% and 46% respectively in the IBLS and DHSS group, the expression rate of Fas antigen in the IBLS group was significant higher than in DHSS group(P＜0.01), showing there was a significant correlation between IBLS pattern and expression rate of Fas antigen(P＜0.01).Conclusion: The result suggested that there was a certain relationship between HP infection and TCM pattern, the positive rates of HP was higher in DHSS pattern compared with the IBLS group. There was a certain relationship between the expression of bcl-2 and Fas in DHSS pattern, IBLS pattern may probably promoted apoptosis in gastritis, whereas HP infection performed as a main role in apoptosis in DHSS pattern. Bcl-2, liP and Fas might contribute to syndrome differentiation of chronic gastritis.

[Objective]To investigate the relationship of TCM syndrome patterns with gastrointestinal motility and hormones in functional dyspepsia (FD). [Methods] Among 30 cases of dyskinetic FD, 16 with liver depression and qi stagnation were allocated to Group B, 14 with spleen and stomach deficiency to Group C and 20 healthy volunteers served as control group ( Group A). Gastric evacuation, elctrogastrogram (EGG), serum motilin and migrating motor complex (MMC) wave of gastric antrum and duodenum during digestion were examined and analysed statistically. [Results]Gastric evacuation, contraction index and amplitude of phase II MMC wave, contraction amplitude and coordinated contraction of phase III MMC wave, and the main power of emptying EGG in empty stomach were decreased in Group B and Group C as compared with those in Group A,and those in Group C were lower than those in Group B, the differences being significant (P

Objective To study the mechanism of Danshi Qing Tablet (DQT) in treating cho lelithiasis. Methods Sixty guinea pigs were randomly allocated to five groups : Group A (normal control), Group B (model control), Group C (treated with low d osage of DQT), Group D (treated with high dosage of DQT) and Group E (treated w ith Xiaorong Gandanjieshi Tablet). Guinea pig models of cholelithiasis were esta blished by subcutaneous injection of lincomycin. Results After six weeks of treatment, the content of the bile acid (BA) was higher and the content of tota l bil irubin TBIL and Ca 2+ was lower in Group C and Group D than those in Group B. The ga llstone formation rate in Group D was 27.27%, which was lower t han that in Group B (80%), the difference being significant (P
