RESUMEN
In order to comprehensively evaluate the quality of Viticis Fructus, this study established HPLC fingerprints and evaluated the quality of 24 batches of Viticis Fructus samples from different species by similarity evaluation and multivariate statistical analysis(PCA, HCA, PLS-DA). On this basis, an HPLC method was established to compare the content differences of the main components, including casticin, agnuside, homoorientin, and p-hydroxybenzoic acid. The analysis was performed on the chromatographic column(Waters Symmetry C_(18)) with a gradient mobile phase of acetonitrile(A)-0.05% phosphoric acid solution(B) at the flow rate of 1 mL·min~(-1) and detection wavelength of 258 nm. The column temperature was 30 ℃ and the injection volume was 10 μL. The HPLC fingerprint of 24 batches of Viticis Fructus samples was established with 21 common peaks, and nine peaks were identified. Similarity analysis was carried out based on chromatographic data of 24 batches of chromatographic data of Viticis Fructus, and the results showed that except for DYMJ-16, the similarity of Vitex trifolia var. simplicifolia was ≥0.900, while that of V. trifolia was ≤0.864. In addition, the similarity analysis of two different species showed that the similarity of 16 batches of V. trifolia var. simplicifolia was 0.894-0.997 and that of the eight batches of V. trifolia was between 0.990 and 0.997. The results showed that the similarity of fingerprints of these two species was different, but the similarity between the same species was good. The results of the three multivariate statistical analyses were consistent, which could distinguish the two different species. The VIP analysis results of PLS-DA showed that casticin and agnuside contributed the most to the distinction. The content determination results showed that there was no significant difference in the content of homoorientin and p-hydroxybenzoic acid in Viticis Fructus from different species, but the content of casticin and agnuside was significantly different in different species(P<0.01). The content of casticin was higher in V. trifolia var. simplicifolia, while agnuside was higher in V. trifolia. The findings of this study show that there are differences in fingerprint similarity and component content of Viticis Fructus from different species, which can provide references for the in-depth study of the quality and clinical application of Viticis Fructus.

With reference to the production process documented in Chinese Pharmacopoeia, this paper prepared the calibrator samples of Xiaochaihu Granules from multiple batches and established a method for fingerprint analysis and content determination that could be used to evaluate Xiaochaihu Granules available in market. Multiple batches of Chinese herbal pieces contained in Xiaochaihu Granules were collected for preparing the calibrator samples according to the process in Chinese Pharmacopoeia. Following the establishment of fingerprints for calibrator samples by UHPLC, the method for determining the contents of saikosaponin B2, saikosaponin B1, baicalin, wogonoside, baicalein, liquiritin, glycyrrhizin G2 and glycyrrhizic acid in Xiaochaihu Granules was established. The experimental results showed that the fingerprints of calibrator samples had 26 common peaks, covering the chemical compounds of main herbs Bupleuri Radix, Scutellariae Radix, Changii Radix, Glycyrrhizae Radix et Rhizoma, and Rhizoma Zingiberis Recens. The similarity of fingerprints for 47 batches of Xiaochaihu Granules from 31 companies with the calibrator sample fingerprint ranged from 0.74 to 0.99, indicating good applicability of the established fingerprint. The contents of main components baicalin, saikosaponin B2, and glycyrrhizic acid in Xiaochaihu Granules were within the ranges of 22.917-49.108 mg per bag(RSD 19%), 0.28-2.19 mg per bag(RSD 62%), and 0.897-6.541 mg per bag(RSD 41%), respectively. The quality difference in saikosaponin B2, and glycyrrhizic acid among different manufacturers was significant. The fingerprint analysis and content determination method for calibrator samples of Xiaochaihu Granules prepared according to the production process in Chinese Pharmacopoeia has been proved suitable for evaluating the quality of Xiaochaihu Granules from different manufacturers. Saikosaponin B2, glycyrrhizic acid, and liquiritin should be added as content control indicators for Xiaochaihu Granules, aiming to further improve the product quality.

Astragali Radix is one of the most commonly used medicinal materials. In recent years, its cultivated varieties and a variety of adulterants have flooded the market, which makes its quality uneven, and the development of quality control methods has become a research hotspot. Therefore, figuring out the quality markers of Astragali Radix is of great significance for its comprehensive evaluation. In this study, the fingerprints of 15 batches of Astragali Radix were established by HPLC, and the main components causing intergroup differences were screened out by PLS-DA. On the basis of literature review and network pharmacology analysis, the targets and pathways of active ingredients were obtained from SwissTargetPrediction, PubChem Compound and other databases, and then the "component-target-pathway" network was constructed with Cytoscape 3.7.1 for the prediction of potential quality markers. Twenty-eight common peaks were identified in the established fingerprint, and three differential components were selected as potential quality markers for Astragali Radix, which were astragaloside Ⅳ, calycosin-7-O-β-D-glucoside and ononin. The proposed method based on HPLC fingerprint of Astragali Radix is convenient and feasible, facilitating the improvement in its quality control.

The brain and heart has a tight relationship upon physiology and pathology during the development of cardiovascular and cerebrovascular diseases with clinical conditions interacting with each other and complex pathological mechanisms. Clinical studies prove that cerebral diseases such as stroke usually happen with cardiac diseases as complications, and cardiac diseases such as atrial fibrillation can also cause cerebral diseases, which can even aggravate brain atrophy and lead to cognitive impairment. Traditional Chinese medicine (TCM) also believes that “the substance of Shenming is located in the brain and the function in the heart.” Specifically, Yuanshen is in the brain and Shishen is in the heart, which thus makes the heart and brain closely related. If Shenming in any of them is impaired, the other one would also be injured. Therefore, the pathological mechanisms of brain-heart mutual damage have become one of the current research hotspots. This paper, combined with the clinical research status of the brain-heart mutual damage, summarized its pathological mechanisms from the perspectives of inflammatory responses, dysregulation of autonomic nervous system, apoptosis, energy metabolism and oxidative stress. The necessity of “brain-heart concurrent regulation” was proposed and the research progress on the treatment of cerebral and cardiac diseases with TCM represented by Naoxintong capsule was profiled in the light of heart and brain function described by TCM and the holistic concept of TCM treating cerebral and cardiac diseases. This paper reviews the pathological mechanisms of brain-heart mutual damage and the research progress on its treatment with TCM, which can provide reference for the prevention and treatment of cardiovascular and cerebrovascular diseases and further research on them.

OBJECTIVE: To observe the auxiliary analgesic effect of wrist-ankle acupuncture on patients undergoing transforaminal endoscope surgery. METHODS: A total of 64 patients with lumbar disc herniation who underwent percutaneous lateral transforaminal endoscope surgery were randomly divided into an observation group and a control group, 32 cases in each group. The patients in the control group were treated with injection of 1% lidocaine for routine local infiltration anesthesia. The patients in the observation group were treated with wrist-ankle acupuncture at lower 5 area and lower 6 area for 30 min, 5 min before routine local infiltration anesthesia; immediately, 15 min, 30 min after insertion the left-right technique, up-down technique, and rotation technique were applied for six times, respectively. The mean arterial pressure (MAP), heart rate (HR), blood oxygen saturation (SpO2) and pain visual analogue scale (VAS) were compared between the two groups at the time points of intraoperative puncture (T1), circular saw grinding (T2), and placement of working channel (T3). The intention of reoperation was recorded immediately after operation and 24 h after operation. The expectation and treatment credibility scale (ETCS) was used to evaluate the relationship between patients' expectation and efficacy 5 min before operation and immediately after operation. RESULTS: At T2 and T3 during the operation, the MAP and HR in the obserrvation group were lower than those in the control group, while SpO2 was higher than that in the control group (P<0.05). At T1, there was no significant difference of MAP, HR and SpO2 between the two groups (P>0.05). At T2, the peak VAS and average VAS in the observation group were lower than those in the control group (P<0.05), but there was no significant difference at T1 and T3 (P>0.05). The intention of reoperation in the observation group was higher than that in the control group both immediately after operation and 24 h after operation (P<0.05). In the observation group, the scores of each item in ETCS immediately after operation were higher than those 5 min before operation (P<0.05), while in the control group there was no significant difference between immediately after operation and 5 min before operation (P>0.05). The scores of ETCS1, ETCS2 and ETCS3 immediately after operation in the observation group were higher than those in the control group (P<0.05). CONCLUSION: The wrist-ankle acupuncture has positive auxiliary analgesic effect on lumbago during transforaminal endoscope surgery, and strengthens the patients' confidence on the operation effect.

RESUMEN
Intestinal absorption liquid was prepared by using everted intestinal sac method; meanwhile, its recipes were decomposed or restructured. Platelet aggregation activity was examined by biochemical tests and a microplate reader. One or more kinds of Chinese medicines which displayed inhibiting activity in Naoxintong Capsules were screened through separation and combination of prescription. The results showed that Naoxintong Capsules could inhibit ADP-induced platelet aggregation. Recipe decomposition and restructuring results showed that Salviae Miltiorrhizae Radix et Rhizoma, Paeoniae Radix Rubra, Cinnamomi Ramulus and Hirudo were the main effective medicines in inhibiting platelet aggregation. Furthermore, Cinnamomi Ramulus played a vital role in inhibiting activity among those four kinds of Chinese medicines. Coumarin derived from intestinal absorption liquid of Cinnamomi Ramulus had inhibiting activity in the range of 50-200 μmol·L⁻¹, and other ingredients such as cinnamyl alcohol and cinnamaldehyde also had inhibiting activities. In conclusion, Salviae Miltiorrhizae Radix et Rhizoma, Paeoniae Radix Rubra, Cinnamomi Ramulus and Hirudo are the main components for inhibiting ADP-induced platelet aggregation, and Cinnamomi Ramulus has the most strongest inhibiting activity in Naoxintong Capsules.

Cardiovascular and cerebrovascular diseases (CCDs) are the primary causes of death in Chinese adults. With the increase in morbidity and mortality rates and the decrease in the age of onset, CCD becomes a very natural target for traditional Chinese medicine. Schisandrae Chinensis Fructus (SCF) is the dry ripe fruit of Schisandra chinensis (Turcz.) Baill., which features a sweet and sour taste and the effects of calming the heart and tranquilizing the mind. It is mainly used for treatment of dysphoria and palpitation, insomnia and dreamful sleep due to the lack of spirit preservation. The main components of SC include lignans, volatile oils and polysaccharides. This review summarized the pharmacological effects of SC and its active components in the treatment of CCDs. The results showed that SCF and its active components protect against cardiovascular diseases mainly through the antioxidant, apoptosis inhibition and anti-inflammatory mechanisms. In addition, they protect against cerebrovascular diseases mainly by increasing energy metabolism, regulating autophagy and inhibiting apoptosis, antioxidant, and regulating nerve neurotransmitters and circadian genes. In conclusion, lignans are the most active components in SCF. This study provides a reference for the clinical research and utilization of SCF, as well as the application basis for co-treatment of cardiovascular and cerebrovascular diseases.
