This study was aimed to analyze the composition principles of prescriptions for sequela of apoplexy collected in the CNKI by the Traditional Chinese Medicine Inheritance Platform (TCMIP), in order to provide a reference for clinical selection of medication. Prescriptions for the sequela of apoplexy treatment in CNKI were collected. Based on the TCMIP, the medication rules of prescription were analyzed by data mining method after data entry. A total of 190 prescriptions involving 204 herbs for sequela of apoplexy treatment were screened and studied. The herbs for blood-activating andqi-tonifying were used with higher frequency. There were 36 commonly used herbal pairs. The herb pair of Dang-Gui(Radix Angelicae Sinensis) andHuang-Qi (Radix Astragali) was with the highest frequency. The herbal combination with three types of herbs wasDi-Long (Pheretima),Dang-Gui andHuang-Qi. The herbal combination with four types of herbs wasChuan-Xiong (Rhizoma Chuanxiong),Di-Long,Dang-Gui andHuang-Qi. The analysis on association rule showed thatChuan-Xiong,Dang-Gui,Tao-Ren (Semen Persicae),Hong-Hua(Flos carthami) andHuang-Qiwere often combined with each other. A total of 48 core combinations and 11 new prescriptions were mined. It was concluded that the prescriptions for sequela of apoplexy were mainly composed with herbs for blood-activating,qi-tonifying and collateral-dredging. According to the flavor and meridian tropism theory of Chinese medicine, the herbal medication selection in the prescription was mostly warm and hot in nature, sweet and pungent flavor, and the meridian tropism of the liver and spleen meridian.

Objective To observe the characteristics of liver-kidney yin deficiency syndrome in late stage of spontaneously hypertension rats (SHRs). Methods Ten 12-month-old healthy male SHRs were put into syndrome observer group (SHR group), while ten male WKY rats with the same age were set as control group (WKY group). Syndrome differentiation method on rats was employed to transform the four-diagnostic information into general behavior indexes with the same significance. The afternoon anal temperature, tongue color, holding power, ability of learning and memory, serum estradiol and testosterone level were observed, compared and analyzed. Results Compared with the WKY group, rats in the SHR group had higher afternoon anal temperature, redder tongues, poorer strength and claw holding power and their ability of learning and memory was retarded; the level of serum estradiol was lower;the ratio of estradiol to testosterone was higher. All of these were largely in line with deficiency of live-kidney yin syndrome. Conclusion SHRs in late stage show characteristics of liver-kidney yin deficiency syndrome.

Objective To investigate the effect of Shanzha Xiaozhi capslue on intima-media thickness(IMT) and plaques score of carotid artery in patients with non-acute phase coronary heart disease and traditional Chinese medicine(TCM)syndrome of phlegm and blood stasis. Methods A prospective study was conducted to carry out a research on 102 patients with non-acute phase coronary heart disease and TCM syndrome of phlegm and blood stasis. They were randomly divided into two groups:a control group(50 cases)treated with conventional western medicine alone and a observation group(52 cases)which was treated by both conventional western medicine and Shanzha Xiaozhi capslue(the main TCM ingredients:Shanzha,Dahuang)0.7 g,3 times a day,the therapeutic course being 6 months in both groups. The cardiocerebral vascular incidences of the two groups were observed,in the mean time,the carotid artery IMT and plagues score were registered,the scores of phlegm stagnation syndrome and blood-stasis syndrome were measured,adverse reaction was observed and compared in both groups before and after treatment. Results After treatment,the occurrence of major adverse acute cardiovascular and cerebrovascular events in observation group were reduced significantly compared with those in the control group(5.77%vs. 20.00%,P<0.05). The IMT and plaques score of carotid artery and the scores of phlegm stagnation syndrome and blood-stasis syndrome were all decreased obviously compared to those before treatment,and the effect was more remarkable in the treatment group〔IMT of carotid artery(mm):0.80±0.13 vs. 0.95±0.12,the plaques score:1.35±0.65 vs. 1.75±0.88, phlegm syndrome score:20.98±6.42 vs. 35.55±9.22,blood-stasis syndrome score:23.23±5.12 vs. 28.95±6.38, P<0.05 or P<0.01〕. Abdominal pain appeared in 2 patients of observation group without other adverse reactions. Conclusion Shanzha Xiaozhi capsule can stabilize atherosclerotic plaque and reduce the occurrence of acute adverse cardiocerebral vascular events in patients with non-acute phase coronary heart disease and phlegm and blood stasis syndrome possibly by removing phlegm and blood stasis to decrease the IMT and plaques score of carotid artery.

OBJECTIVETo study the influence of aconite root, a Chinese medicinal herb with hot property, on energy metabolism and gene expression spectrum, and to analyze the possible mechanism of it effect.

METHODThirty two SPF Wistar rats were randomly divided into aconite root group and control group. Decoction of aconite root and NS were intragastrically administrated with the concentration of 10 mL x kg(-1) respectively once a day for 20 days. Temperature, energy intake (EI), digestive energy (DE) and metabolic energy (ME) were measured. The activity of ATPase and succinate dehydrogenase (SDH) in liver was detected by colorimetry. The gene expression of liver was detected with Illumina's rat ref-12 gene array. The differential expression genes were selected, annotated and classified based on gene ontology (GO). Real-time quantitative reverse-transcriptase PCR (Q-RT-PCR) was used to test the accuracy of the array results.

RESULTCompared with the control group, the toe temperature (TT) on the 10th and 20th day after the administration,the EI/BM( body mass), DE/BM, ME/BM and the activity of Na+ - K+ - ATPase, Ca2+ - Mg2+ - ATPase and SDH of liver in the aconite root group increased significantly (P<0.05). There were 592 differential expression genes in aconite root group compared with the control group. Based on Go analysis, the most significant genes was related to metabolic process (lgP = - 15.5897).

CONCLUSIONAconite root could improve the energy metabolism in rats, by influencing the metabolic process of sugar, lipid and amino acid, which may be the main molecular mechanism of warming yang and dispelling cold for the treatment of the cold syndrome according to Chinese medicine theory.

Objective: To analyze the molecular characteristics of Listeria monocytogenes strains from ready-to eat food in China. Methods: A total of 239 Listeria monocytogenes strains isolated from ready-to-eat food in 2017, all strains underwent whole-genome sequencing (WGS) , and comparisons uncovered population structure derived from lineages, clonal complex, serogroups, antimicrobial susceptibility and virulence, which were inferred in silico from the WGS data. Core genome multilocus sequence typing was used to subtype isolates. Results: All strains were categorized into three different lineages, lineage Ⅱ was the predominant types in food, and IIa was the main serogroups. CC8, CC101 and CC87 were the first three prevalent CCs among 23 detected CCs, accounting for 49.4%. Only 4.6% (11 isolates) of tested strains harbored antibiotic resistance genes, which were mostly trimethoprim genes (7 isolates, 2.9%). All strains were positive for LIPI-1, and only a part of strains harbored LIPI-3 and LIPI-4, accounting for 13.8% (33 isolates) and 14.2% (34 isolates), respectively. ST619 carried both LIPI-3 and LIPI-4. 51.5% (123 isolates) of strains carried SSI-1, and all CC121 strains harbored SSI-2. Different lineages, serogroups and CCs can be separated obviously through cgMLST analysis, and 24 sublineages were highly concordant with CCs. Conclusion Ⅱa was the main serogroups in ready-to-eat food isolates in China; CC8, CC101 and CC87 were the prevalent CCs, and CC87 isolates was hypervirulent isolates, cgMLST method can be adopted for prospective foodborne disease surveillance and outbreaks detection.
