OBJECTIVE To establish the ultra-high liquid chromatography （UPLC） characteristic spectrum of Uncariae Ramulus Cum Uncis from different producing areas， to conduct chemical pattern recognition analysis， and to identify the medicinal materials of their different origins and counterfeit products. METHODS UPLC method was adopted to establish the characteristic spectra of 43 batches of Uncariae Ramulus Cum Uncis from different origins； cluster analysis combined with principal component analysis were used to analyze their quality； Uncariae Ramulus Cum Uncis from different origins and counterfeit products were identified. RESULTS UPLC specific spectrum of Uncariae Ramulus Cum Uncis was established， and 13 common peaks were calibrated； peak 2 was identified as catechin， peak 3 as chlorogenic acid， peak 4 as cryptochlorogenic acid， peak 7 as isochlorogenic acid B， peak 8 as isodehydroguotenine， peak 9 as isooguotenine， peak 10 as dehydroguotenine， peak 11 as isochlorogenic acid C， peak 12 as goutenine， and peak 13 as camptothecin. Through cluster analysis， the medicinal materials of 43 batches of Uncariae Ramulus Cum Uncis could be divided into 5 categories according to their different origins. Further principal component analysis revealed that the principal component comprehensive scores of Uncariae Ramulus Cum Uncis produced in Jiangxi and Hunan were relatively high， ranging from 0.264 to 2.904. The specific chromatogram could effectively distinguish among the different origins and their counterfeit products of Uncariae Ramulus Cum Uncis. CONCLUSIONS The established UPLC specific chromatogram can be used for quality control of Uncariae Ramulus Cum Uncis， and the study found that the quality of Uncariae Ramulus Cum Uncis from Jiangxi and Hunan provinces is relatively good.

Gastrointestinal motility disorder is an important cause of digestive system diseases. Patients often suffer from nausea， vomiting， gastric retention， gastroparesis， constipation， and many other symptoms， and their quality of life is seriously reduced. Prokinetic agents are routinely used in clinical practice， but their long-term use is prone to problems such as reduced efficacy and increased adverse reactions. Since the incidence of gastrointestinal diseases has continued to rise globally in recent years， there is an urgent need for clinical development of safe and effective treatment strategies. Aurantii Fructus， a traditional Chinese medicine， has the effect of smoothing Qi and eliminating distention， and it has been used to treat gastrointestinal diseases for thousands of years. In modern clinical practice， it is mainly used for the treatment and auxiliary treatment of various gastrointestinal diseases such as functional dyspepsia， functional constipation， and irritable bowel syndrome. The efficacy is remarkable， and no adverse reactions have been reported at conventional doses. Therefore， it can greatly improve the symptoms of patients with gastrointestinal diseases and improve their quality of life. Modern research has revealed that there are many active components in Aurantii Fructus， among which flavonoids have the highest content and the most types. Flavonoids are the main active components in Aurantii Fructus to regulate gastrointestinal motility. Aurantii Fructus and its active components can affect gastrointestinal hormones， neural pathways， Cajal mesenchymal cells， and other multiple mechanisms. They can adjust gastrointestinal motility and correct gastrointestinal motility disorders， showing potential application value in the treatment of gastrointestinal motility disorders. However， a comprehensive analysis of Aurantii Fructus in this aspect is still lacking. This study summarized the pharmacological activities of active components of Aurantii Fructus extract and its flavonoids， volatile oils， alkaloids， and coumarin on the regulation of gastrointestinal motility and explored the latest research progress on its mechanism. Finally， the adverse reactions of Aurantii Fructus were summarized. It aims to provide a scientific basis for the research and clinical application of Aurantii Fructus and its active components in the regulation of gastrointestinal motility.

OBJECTIVE To ascertain the substance benchmarks of the classic prescription Huangqi Guizhi Wuwu Decoction(HGWD),examine the quantitative value transfer throughout the entire process of HGWD,from herb pieces to decoction,concentrated solution and finally freeze-dried powder,and provide a valuable reference for the preparation method and scientific evaluation of bench-mark samples of classic prescriptions containing volatile substances.METHODS According to the Key information table of Ancient Classic Prescriptions(25 prescriptions)released by China,15 batches of HGWD were prepared.The multi-index content determination and characteristic chromatogram analysis methods were established,and the characteristic peak attribution and similarity evaluation were carried out.The multi-index contents of HGWD and its freeze-dried powder were investigated and compared,and the quantitative value transfer in the preparation process of decoction-concentrated solution-freeze-dried powder was analyzed.The physical form of the benchmark samples were scientifically and reasonably determined,and the content and transfer rate range of each component in the HGWD benchmark samples were determined,and the HGWD substance benchmarks were established.RESULTS The contents of cinnamaldehyde and cinnamyl alcohol in HGWD decreased significantly during the concentration and drying process,and the other in-dex components could be transferred more completely between the decoction,concentrated solution and freeze-dried powder.The simi-larity of the characteristic chromatograms of 15 batches of HGWD benchmark samples were all over 0.9,and 8 characteristic peaks were identified,which were from Paeoniae γadix Alba,Cinnamomi γamulus and Ginger.The paste-forming rate ranged from 8.0%to 11.0%.The content of Astragaloside Ⅳ was 0.04%-0.07%and the transfer rate was 9.0%-18.0%.The content of paeoniflorin was 1.5%-3.0%and the transfer rate was 33.0%-62.0%.The content of cinnamyl alcohol was 0.02%-0.04%,and the transfer rate was 25.0%-47.0%.The content of cinnamic aldehyde was 0.02%-0.05%and the transfer rate was 0.7%-1.5%.The content of cinnamic acid was 0.03%-0.06%and the transfer rate was 17.5%-34.0%.The content of 6-gingerol was 0.04%-0.08%and the transfer rate was 7.0%-14.0%.CONCLUSION The physical form of the decoction as the HGWD benchmark sample is deter-mined,which provides reference for the scientific selection of the physical form of the benchmark sample of classic prescriptions contai-ning volatile substances.The quality indexes of HGWD substance benchmarks are established,and the quantitative value transfer is an-alyzed,which provides the basis for the development of the classic prescription compound preparation.

Meta-analysis showed that age [MD=2.56, 95%CI (1.61, 3.52), P<0.001], hypertension [OR=1.77, 95%CI (1.18, 2.66), P<0.001], EuroSCORE Ⅱ score [MD=0.70, 95%CI (0.34, 1.06), P<0.001], frequent atrial premature beats or atrial tachycardia [OR=3.77, 95%CI (2.13, 6.68), P<0.001], left atrium diameter (LAD) [MD=1.64, 95%CI (0.26, 3.03), P=0.010], left ventricular ejection fraction (LVEF) [MD=−1.84, 95%CI (−2.85, −0.83), P<0.001], right coronary stenosis [OR=2.49, 95%CI (1.29, 4.81), P=0.006], three-vessel coronary artery lesions [OR=0.73, 95%CI (0.54, 0.97), P=0.030], not using β blockers [OR=0.81, 95%CI (0.69, 0.96), P=0.010], operation time [MD=10.13, 95%CI (8.15, 12.10), P<0.001], duration of mechanical ventilation [OR=2.85, 95%CI (1.79, 3.91), P<0.001] were risk factors for new-onset atrial fibrillation after OPCABG. Conclusion Advanced age, hypertension, high EuroSCOREⅡ score, frequent atrial premature beats or atrial tachycardia, increased LAD, decreased LVEF, right coronary stenosis, three-vessel coronary artery lesions, not using β blockers, prolonged operation time and mechanical ventilation are risk factors for new-onset atrial fibrillation after OPCABG. Due to factors such as the methodology, content and quality of the included literature, the conclusion of this study need to be supported by more high-quality studies.

Objective:To investigate the protective effects of Huoxue Rongluo Decoction on hypoxic-ischemic brain damage (HIBD) rats; To clarify the expression of AMPK signaling pathway during HIBD injury and repair.Methods:On the basis of the hypoxia ischemia reperfusion model, an improved hypoxia bottle was used to establish a full-term HIBD rat model. Totally 60 successfully modeled mice were divided into model group and TCM group using a random number table method, with 30 mice in each group and 30 mice in a control group. Two hours before surgery, TCM group was orally administered with Huoxue Rongluo Decoction 1.17 g/100 g (equivalent dose). The control group and model group were orally administered with equal volume of physiological saline. Two hours after surgery, it was orally administered again, twice a day, for consecutive 5 d. Behavioral tests (convulsion assessment, Longa score, suspension test, water maze test) were used to evaluate the motor nerve function and long-term learning ability of young rats in different groups. HE staining and electron microscopy were used to observe the pathological changes of brain tissue and mitochondrial damage. Evans blue (EB) staining and brain water content measurement were used to detect blood-brain barrier permeability and brain edema. The expression of AMPK signaling pathway related genes in brain tissues of different groups of young rats was detected by PCR array technique.Results:Compared with the model group, the convulsions of the rats in the TCM group were improved, the Longa score was significantly reduced, the grip strength test score and suspension time were significantly improved, the escape latency was significantly shortened, and the number of crossing platforms significantly increased ( P<0.05); the degree of neuronal and mitochondrial damage in the TCM group was reduced, and cerebral vascular permeability and brain water content were significantly reduced ( P<0.01). The results of PCR array showed that compared with the control group, 2 genes were significantly up-regulated and 12 genes were significantly down-regulated in the brain tissue of the model group; compared with TCM group, 15 genes were relatively down-regulated in the model group. Conclusion:Huoxue Rongluo Decoction can significantly reduce the degree of brain injury after HIBD, improve the motor nerve function and long-term learning and cognitive ability of model rats, and its damage repair mechanism is related to the expression regulation of AMPK signaling pathway related genes.
