Yangjing Zhongyu Tang, from FU Qing-zhu Nvke, is a famous classical formula of clinical value for treating blood deficiency syndrome of female infertility in the Qing dynasty. The prescription seems plain, but it is rigorous and effective with high research value. In this paper, the ancient books and modern documents of Yangjing Zhongyu Tang were analyzed from the aspects of traceability of Chinese materia medica in the formula, pharmacological research, clinical research, etc. It could be concluded that the pharmacological studies of this formula were mostly to investigate the mechanism and efficacy of its treatment for infertility, but there was a lack of comprehensive interpretation of the structure, function and principle of pharmacodynamic substance in this formula. In this paper, combined with the contents of supramolecular imprinting template and network pharmacology, the new direction of pharmacological research of Chinese medicine compound was put forward. Quality control of Yangjing Zhongyu Tang mostly based on small molecule compounds, so it was suggested to break the inherent thinking, and increase the detection of macromolecule compounds and supramolecular of Chinese materia medica. The druggability of this formula involved in the preliminary study of decoctions, plasters and granules. Considering the quality stability of Chinese materia medica in the formula and the scientificity of druggability of this formula, the compatibility principle of traditional Chinese medicine (TCM) and modern supramolecular chemistry theory could be combined to study the change law of druggability of TCM before and after compatibility, so as to provide new reference materials for the follow-up clinical application and development of Yangjing Zhongyu Tang.

Objective: Based on the analysis of the total components of fingerprint and the determination methods of the existing components in the 2015 edition of Chinese Pharmacopoeia, the "point-line-surface" quality standard of Yangjing Zhongyu Tang was established by the "point" of each single component (morroniside, loganin, paeoniflorin, ferulic acid and verbascoside) to the "line" of multicomponent and the "face" of fingerprint of the whole component. Method: XB-C₁₈ column (4.6 mm×250 mm, 5 μm) was used for gradient elution of 0.1% phosphoric acid aqueous solution-acetonitrile. The column temperature was 30℃, the injection volume was 10 μL, the flow rate was 1.0 mL·min^-1, and the detection wavelengths were 240, 316, 230, 334 nm. The contents of these five components in Yangjing Zhongyu Tang were determined by three correction methods, external standard method and regression equation method. At the same time, the fingerprint of Yangjing Zhongyu Tang were analyzed by total component analysis and similarity evaluation. Result: With ferulic acid as reference, the relative correction factor (f) of morroniside, loganin, paeoniflorin and verbascoside were 0.392 1, 0.421 4, 0.261 7, 0.268 6 by multi-point correction method, and their f (slope correction method) were 0.385 4, 0.419 4, 0.255 9, 0.274 0, respectively. Twenty characteristic peaks of fingerprint were analyzed and the similarity was ≥ 0.999.There was no significant difference in the contents of these five components from Yangjing Zhongyu Tang determined by the quantitative assay of multi-components by single-marker (QAMS) correction method, the external standard method and the regression equation method. Conclusion: The comprehensive quality standard established by the total component analysis of fingerprint combined with various determination methods of existing components in the 2015 edition of Chinese Pharmacopoeia has been validated in famous classical formula of Yangjing Zhongyu Tang, which can provide ideas and methods for the quality control with quantitative determination and fingerprint of other famous classical formulas.

Objective: To observe the changes of dysfunctional high density lipoprotein cholesterol (dyHDL) and the intervention effect of Xiangsha Liu Junzitang in rats with spleen deficiency and hyperlipidemia, and reveal the effect and mechanism of Xiangsha Liu Junzitang on dyHDL in rats with spleen-deficiency hyperlipidemia. Method: Seventy-five SPF SD rats were randomly divided into normal group, high fat group, spleen deficiency and high fat group, Xiangsha Liu Junzitang low and high dose groups (5.67, 11.34 g·kg^-1). In the spleen deficiency and high fat group, as well as Xiangsha Liu Junzitang low and high dose groups, composite method of improper diet and exhaustive swimming was used for 15 days for modeling. After modeling for 15 days, normal group was fed with basic diet, while the high-fat group, spleen-deficiency and high-fat group, the Xiangsha Liu Junzitang low and high dose groups were fed with high-fat diet. After 12 weeks, the Xiangsha Liu Junzitang low dose and high dose groups received corresponding dosage of drugs, while normal group, high fat group and spleen deficiency high fat group received corresponding volume of normal saline. After 4 weeks, the contents of total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol cholesterol (LDL-C), and high density lipoprotein cholesterol(HDL-C)were detected by automatic biochemistry analyzer, while D-xylose excretion rate was measured by phloroglucinol method. The morphological changes of liver cells were observed by hematoxylin eosin (HE) staining. The level of PON1, apoA1 and SAA in plasma were detected by enzyme-linked immunosorbent assay (ELISA). Paraoxonase 1(PON1), apolipoprotein A1 (apoA1) and serum amyloid protein A (SAA) gene expression in rats liver were detected by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). Result: As compared with normal group, the serum TC, TG, and LDL-C levels were significantly increased in the high-fat group and spleen-deficiency high-fat group (P<0.05), and HDL-C levels were significantly lower (P<0.05); the levels of PON1 and apoA1 in plasma were decreased (P<0.05), while the content of SAA was increased (P<0.05); the expression of SAA gene in liver tissues was increased (P<0.01), and the expression levels of PON1 and apoA1 genes in liver tissues were significantly decreased (P<0.01). In high-fat group and the spleen-deficiency and high-fat group, the hepatocytes were rounded and scattered, and scattered fat vacuoles were observed. In addition, the urinary D-xylose excretion rate was significantly decreased in the spleen-deficiency and high-fat group (P<0.05). After the intervention with Xiangsha Liu Junzitang, the serum TC, LDL-C levels were significantly decreased (P<0.05); HDL-C levels were significantly increased (P<0.05); plasma PON1, apoA1 levels were increased (P<0.05); the content of SAA was decreased (P<0.05); the expression of SAA gene in liver tissues was decreased (P<0.05); the expression of apoA1 gene was increased significantly (P<0.05). Liver cells swelling was significantly alleviated and fat foaming was reduced. As compared with high-fat group, the plasma PON1 and SAA levels in the spleen-deficiency high-fat group were significantly lower (P<0.05); hepatocyte swelling was obvious and foaming was aggravated. Conclusion: The lipid disorder in hyperlipidemia rats was aggravated by the spleen deficiency, but was corrected after intervention with Xiangsha Liu Junzitang. and its mechanism may be related to the regulation of the expression of dyHDL-related genes and protein.

Objectives: To evaluate the changes of left atrial volume (LAV) and the maximum ostial cross-sectional area (CAS) of pulmonary vein (PV) in atrial fibrillation (AF) patients after circumferential pulmonary vein isolation radiofrequency catheter ablation (CPVA-RFCA) and to explore their relationship to AF recurrence by enhanced cardiac MRI evaluation. Methods: Our research included in 2 groups: Control group, n=20 healthy subjects and AF group, n=78 patients whom were classified into 2 subgroups as Paroxysmal AF subgroup, n=46 and Persistent AF subgroup, n=32; 66 patients received CPVA-RFCA and based on 6 months post-operative recurrence, they were divided into another set of 2 groups: AF recurrent subgroup, n=17 and Non-AF recurrent subgroup, n=49. Pre- and 6 months post-operative maximum ostial CSA of PV were measured by enhanced cardiac MRI, LAV were obtained by 3D reconstruction and the differences were compared between AF group and Control group, Paroxysmal AF subgroup and Persistent AF subgroup, AF recurrent subgroup and Non-AF recurrent subgroup; their relationships to AF recurrence were studied.Results: Compared with Control group, AF group had increased LAV and elevated ostial CSA of superior PV (SPV), both P<0.05. Compared with Paroxysmal AF subgroup, Persistent AF subgroup had increased LAV and elevated ostial CSA of SPV, both P<0.05. Compared with pre-operative condition, at 6 months after the operation, Non-AF recurrent subgroup showed reduced ostial CSAs in left SPV (LSPV), right SPV (RSPV), right inferior PV (RIPV) and decreased LAV, all P<0.05;while AF recurrent subgroup showed expanded RSPV and increased LAV,allP<0.05.Post-operative reductions of LAV and ostial CSA of SPV had close correlation; multivariate Logistic regression analysis indicated that LAV (HR=1.05, P<0.01)and ostial CSA of RSPV(HR=1.09,P=0.05)were related to AF recurrence after RFCA. Conclusions: CAPV-RFCA could reverse left atrial and PV remodeling in AF patients, LAV and ostial CSA of RSPV were related to post-operative AF recurrence.

To explore the clinical application features of Qingkailing injection for adolescent patients. This study was based on the information from the hospitalized patients in 1998-2011 in HIS (hospital information system) of 16 tertiary hospitals in China. 615 adolescent patients with Qingkailing injection were used to investigate the clinical characteristics of Qingkailing injection. Apriori algorithm was adopted to establish the model, and Clementine 12.0 was used for correlation analysis. The results showed that male patients (355 cases) were more than female patients (243 cases); the age of the most patients was under 14 years old, with an average age of 9.40 years old; the hospital stay was most of 4-7 d; the patients were mostly concentrated in pediatrics, mainly including upper respiratory tract infection; outpatient admission to the majority (451 cases, accounting for 75.54%). The traditional Chinese medicine (TCM) syndrome mainly included phlegm-dampness internal resistance (38.46%), Qi and Yin Deficiency (11.54%), Liver qi stagnation (15.38%), and Yang deficiency syndrome (11.54%); the highest admission rate was during Slight Cold (13.01%). In combined application, the most common western medicine pair was Cephalosporin injection+vitamin C (with supporting rate of 24.6%) and the most common TCM pair was Shuanghuanglian+Ganmao Qingre granules (with supporting rate of 4.065%). The most common 3 western medicines in combined use were Potassium chloride injection+Cephalosporin injection+vitamin C (supporting rate of 15.93%); while the most common three Chinese medicines were Shuanghuanglian+Yunnan Baiyao+Ganmao Qingre granules (supporting rate of 1.138%). Qingkailing injection was also widely used in adolescent patients; the diagnosis and use were basically in line with the instructions; men were slightly more than women; age of onset, solar terms and TCM syndromes were highly consistent. Qingkailing injection was mainly combined with western medicines in combined drug use, and Chinese medicines were also available. Combined drug use was more reasonable. Based on the results of the real world HIS, Qingkailing injection could provide the idea and reference for regulating the medication in adolescent patients.
