Published：2021-08-27 - Abstract：To study the changes of adenosine diphosphate (ADP)-induced platelet aggregation rate, and evaluate the effects of Maixuekang Capsule (脉血康胶囊, MKC) on platelet aggregation rate and long-term prognosis of patients with acute coronary syndrome after percutaneous coronary intervention (PCI). A total of 236 patients with acute coronary syndrome, who received successful PCI, were randomly assigned to a trial group (116 cases) and a control group (120 cases) according to random numbers; treatment allocation occurred when the participants met the inclusion criteria and signed the informed consent forms. In the trial group, the patients were treated with MKC combined with routine medication, and in the control group the patients were treated with routine medication. The therapeutic course for the two groups was 12 months and the follow-up was 12 months. The levels of ADP-induced platelet aggregation rate and serum high-sensitive C-reactive protein (hs-CRP) were determined before PCI, 12 h and 30 days after PCI. In the meantime, the incidence of cardio-/cerebrovascular events was recorded during the 12-month follow-up. Compared with before PCI, the levels of ADP-induced platelet aggregation rate and serum hs-CRP were significantly higher at 12 h after PCI (P<0.05). They were significantly reduced after 30-day-treatment of MKC, showing statistical differences when compared with those in the control group (P<0.05). During the 12-month follow-up, the incidence of cardio-/cerebrovascular events was significantly lower in the trial group than in the control group (6.9% vs. 12.5%, P<0.01). ADP-induced platelet aggregation function was significantly elevated after PCI. MKC improved the prognosis of patients with acute coronary syndrome, possibly through inhibiting the platelet aggregation, fighting against inflammation, and protecting the vascular endothelial function.Keywords：acute coronary syndrome;platelet aggregation inhibitors;Percutaneous Coronary Intervention;Maixuekang Capsule

Chinese medicine syndrome distribution of chronic hepatitis b virus carriers in immunotolerant phase
Abstract：To explore Chinese medicine (CM) syndrome distribution of chronic hepatitis B virus (HBV) carriers in immunotolerant phase (ITP). One hundred and eighty-five chronic HBV carriers in ITP, seen in the Third Affiliated Hospital of Sun Yat-sen University from May 2009 to December 2010, were admitted in an observational study under the guidance of CM. Patients’ CM symptoms and signs, demographics, liver biochemistries, and qualitative HBV DNA were recorded in the questionnaires. CM syndromes were then differentiated to 15 detailed types and analyzed by generalization. Lastly, the location, pathogenic factors and nature of the disease were also assessed. When CM syndrome patterns were differentiated to 15 types, there were 27 (15%) no syndrome cases, 94 (50%) single syndrome cases and 64 (35%) compound syndromes cases. The main detailed syndromes included Liver (Gan)-qi depression (LQD), Kidney (Shen)-qi deficiency (KQD), Spleen (Pi)-qi deficiency (SQD) and Kidney-yang deficiency (KYAD). After CM syndromes generalized to five types, their frequency was Spleen-Kidney deficiency (SKD)>LQD>inner dampness-heat retention (IDHR)>Liver-Kidney deficiency (LKD)>blood stasis blocking collateral (BSBC). SKD and LQD occupied 64%. The disease location included Liver, Gallbladder (Dan), Spleen, Stomach (Wei) and Kidney. The pathogenic factors were mainly qi stagnation, qi deficiency, yang deficiency, concurrently dampness-heat and blood stasis. The deficiency syndrome was more than excess syndrome in its nature. Most of chronic HBV carriers in ITP have their CM syndrome, and the most common types are SKAD, LQD. This study suggests that the natural history may be improved through breaking the state of immune tolerance or shorten the time of ITP by strengthening Spleen-Kidney and reliving Liver qi.Keywords：hepatitis B virus carrier;natural history;immune tolerance;Chinese Medicine;Syndrome Differentiation- 840

Published：2021-08-27 - Abstract：To investigate Chinese medicine (CM) patterns and epidemiological characters of patients with influenza-like illness (ILI) syndromes in clinics in China. A prospective multi-center observational epidemiology survey on the clinical CM patterns of ILI and its prevalence was conducted from September 2009 to April 2010. A unified survey questionnaire was developed for data collection of ILI symptoms and CM patterns. Totally 45 hospitals from 22 provinces, municipality cities and autonomous regions of China participated this study. The collected data were input by EPI-data v3.1 and analyzed by SPSS 18.0, which included descriptive analysis and Chi-square test for group comparison. A total of 5,967 ILI patients were included in the study. The proportion of the 18–34 aged group (56.2%) was the largest; students (41.0%) were more than other occupations. Majority of the patients had the wind-heat invading Lung (Fei) syndrome (76%), while in Southwest China mainly wind-heat invading Lung syndrome and wind-cold tightening the exterior syndrome occurred. The typical symptoms of ILI were ranked as fatigue (80.9%), cough (72.2%), sore throat (67.2%), muscular soreness (67.1%), headache (65.4%), aversion to cold (60.1%), thirst (55.1%) and nasal obstruction (48.1%). The ILI patients in clinics were mainly teenagers and young adults. In regard to CM syndrome, wind-heat invading Lung syndrome prevailed in all regions except the Southwest China. The characteristics of CM syndrome of ILI patients may be relevant to age and region distribution.Keywords：clinic;influenza-like cases;Chinese medicine syndrome;epidemiology;multi-center survey

Published：2021-08-27 - Abstract：To investigate the effects and underlying molecular mechanisms of icariin (ICA) on self-renewal and differentiation of neural stem cells (NSCs). NSCs were derived from forebrains of mice embryos by mechanical dissociation into single cell suspension. The self-renewal of NSCs was measured by neurosphere formation assay. The proliferation of NSCs was detected by water-soluble tetrazolium (WST) and 5-ethynyl-2′-deoxyuridine (EdU) incorporation assay. Protein expression of neuron-specific marker tubulin-βIII(TuJ1) and astrocyte-specific marker glial fibrillary acidic protein (GFAP) were measured by immunofluorescence and Western blotting. Using microarray, the differentially expressed genes (DEGs) were screened between NSCs with or without ICA treatment. The signaling pathways enriched by these DEGs and their role in mediating effects of ICA were analyzed. ICA significantly promoted neurosphere formation of NSCs cultured in growth protocol in a dose-dependent manner and achieved the maximum effects at 100 nmol/L. ICA also increased optical absorbance value and EdU incorporation into nuclei of NSCs. ICA had no significant effects on the percentage of TuJ1 or GFAP-positive cells, and TuJ1 or GFAP protein expression in NSCs cultured in differentiation protocol. A total of 478 genes were found to be differentially regulated. Among signaling pathways significantly enriched by DEGs, mitogen activated protein kinase (MAPK) pathway was of interest. Blockade of extracellular signal-regulated kinase (ERK)/MAPK, other than p38/MAPK subfamily pathway partially abolished effects of ICA on neurosphere formation and EdU incorporation of NSCs. ICA can promote the selfrenewal of NSCs at least partially through ERK/MAPK signaling pathway.Keywords：icariin;neural stem cells;self-renewal;differentiation;extracellular signaling-regulated kinase

Published：2021-08-27 - Abstract：To investigate the neuro-protective effects of baicalin in Wistar rats with focal cerebral ischemic reperfusion injury. Ninety adult male Wistar rats weighing 320–350 g were randomly divided into the following groups (n=5): (a) sham control group; (b) vehicle group, subjected to middle cerebral artery occlusion and received vehicle intraperitoneally; (c-e) baicalin groups, which were subjected to the middle cerebral artery occlusion and treated with baicalin 25, 50 and 100 mg/kg, respectively. The neurological scores were determined at postoperative 1, 3 and 7 d after the treatment. The expression of protease-activated receptor-1 (PAR-1), PAR-1 mRNA and Caspase-3 were determined using Western blot, reverse transcription polymerase chain reaction (RTPCR) analysis and immunohistochemistry, respectively. Significant decrease was noted in the neurological score in the baicalin group compared with that of the vehicle group (P<0.01). Additionally, down-regulation of PAR-1 mRNA, PAR-1 and Caspase-3 was observed in the baicalin groups compared with those obtained from the vehicle group (P<0.01). Compared with the low-dose baicalin group (25 mg/kg), remarkable decrease was noted in neurological score, and the expression of PAR-1 mRNA, PAR-1 as well as Caspase-3 in the high-dose group (P<0.05). Baicalin showed neuro-protective effects in focal cerebral ischemic reperfusion injury through inhibiting the expression of PAR-1 and apoptosis.Keywords：Baicalin;cerebral ischemia-reperfusion;protease-activated receptor-1;caspase-3;neuroprotection

Published：2021-08-27 - Abstract：To evaluate the effect of Bear Bile Powder(熊胆粉, BBP) on the growth and apoptosis of HepG2 human hepatocellular carcinoma cells, and investigate the possible molecular mechanisms mediating its anti-cancer activity. HepG2 cells were treated with 0.4–1.0 mg/mL of BBP for 24, 48 and 72 h. The viability of HePG2 cells was determined by MTT assay. Cellular morphology was observed via phase-contrast microscopy. Fluorescence-activated cell sorting analysis with Annexin-V/propidium idodide and 5,5′,6,6′-tetrachloro-1,1′,3,3′-tetraethyl-benzimidazol-carbocyanine iodide (JC-1) staining was performed to determine cell apoptosis and the loss of mitochondrial membrane potential, respectively. Activation of caspase-9 and -3 was evaluated by a colorimetric assay. The treatment with 0.4–1 mg/mL of BBP for 24, 48, or 72 h respectively reduced cell viability significantly by 7%–60%, 20%–90% or 25%–98%, compared with the untreated control cells (P<0.01). In addition, BBP treatment induced morphological changes in HepG2 cells. Furthermore, after treated with 0, 0.4, 0.6, 0.8 and 1.0 mg/mL of BBP, apoptosis cells (including early and late apoptotic cells) were 18.0%±1.3%, 34.9%±2.2%, 33.9%±2.8%, 37.4%±2.8% and 46.0%±2.5%, respectively (P<0.05); and the percentage of cells with reduced JC-1 red fluorescence were 6.6%±0.8%, 8.5%±0.8%, 13.5%±1.6%, 17.6%±2.3% and 46.7%±3.6%, respectively (P<0.01). Finally, BBP treatment significantly and dose-dependently induced activation of both caspase-9 and caspase-3 in HepG2 cells (P<0.05). BBP could inhibit the growth of HepG2 hepatocellular cancer cells through mitochondrion-mediated apoptosis, which may, in part, explain its anti-cancer activity. BBP may be a potential novel therapeutic agent for the treatment of hepatocellular carcinoma.Keywords：bear bile powder;hepatocellular carcinoma;apoptosis;mitochondria

Published：2021-08-27 - Abstract：To investigate the influence of acupuncture parameters on the acupuncture effect through the cluster analysis in Wistar rat model with middle cerebral artery occlusion (MCAO). Duplicated MCAO models by Zea-longa’s thread ligation and chose rats with 1–3 scores assessed by Zausinger’s six-score method to be grouped. The rats were divided into 6 basic control groups [(including a normal group, a sham group, a model control group, a model group without intervention, a Nimodipine group, a lateral-to-Renzhong (DU6) group] and 6 acupuncture groups [a Neiguan (PC6) group, a Weizhong (BL40) group, a Sanyinjiao (SP6) group, a Chize (LU5) group, a Renzhong (DU6) group and a Feixue (non-acupoint) group]. In the acupuncture groups, for every acupoint or needling site, 9 different parameters [2 factors (frequency and time) and 3 levels (180, 120, and 60 cpm of the frequency and 5, 60, and 180 s of the time)] were set respectively by the orthogonal intersection method, in total 54 groups. The rats were treated by acupuncture with a lifting-thrusting manipulation once every 12 h, in total 6 times. Neurobehavioral scores, cerebral blood flow, infarction rate, microcirculation, light microscopy, etc. were measured. The factor analysis was first applied to get the comprehensive effect scores of the samples in the acupuncture groups and then by which the cluster analysis was made with the statistical software of SPSS17.0. For the Neiguan (PC6) group, the exceptional results of acupuncture comprehensive effect were parameters 7, 8, 9, 10; the valid results were parameters 2, 3, 4, and the invalid were parameters 5, 6. For the Weizhong (BL40) group, the exceptional results were parameters 2, 4; the valid results were parameters 3, 5, 6, 7, and the invalid were parameters 8, 9, 10. For the Chize (LU5) group, the exceptional results were parameters 7, 8; the valid results were parameters 3, 4, 5, 6, 9, 10; and the invalid was parameter 2. For the Sanyinjiao (SP6) group, the exceptional results were parameters 4, 6; the valid results were parameters 2, 3, 5; and the invalid were parameters 7, 8, 9,10. For the Renzhong (DU6) group, the exceptional results were parameters 3, 4, 6, 7, 9, 10; the valid results were parameters 2, 5; and the invalid was parameter 8. For the Non-acupoint group, the exceptional result was parameter 10; the valid results were parameters 2, 3, 4, 7, 9; and the invalid were parameters 5, 6, 8. For each meridian acupoint, different acupuncture parameters could consequently get a different acupuncture effect; each meridian acupoint had the most suitable or optimal acupuncture parameters; acupuncture parameters might be the main factors impacting on acupuncture effect.Keywords：middle cerebral artery occlusion;acupuncture parameters;acupuncture effect;cluster analysis;rat

Published：2021-08-27 - Abstract：To critically evaluate the currently available randomized clinical trials regarding the effectiveness of acupuncture in palliative care for cancer patients, hence, to provide sufficient evidences for the widespread use of acupuncture in cancer treatment. Two independent reviewers extracted data from all of the randomized clinical trials (RCTs) that assessed the efficacy of acupuncture in palliative care for cancer patients. Seven databases were searched from their respective inception to December 2010. All eligible trials identified were evaluated by two independent reviewers using the Jadad scale, and data from the articles were validated and extracted. In total, 33 RCTs met the inclusion criteria. The effects of acupuncture on different cancer-related aspects were shown, including chemotherapy or radiotherapy-induced side effects (13/33, 39.4%), cancer pain (6/33, 18.2%), post-operative urinary retention (4/33, 12.1%), quality of life (2/33, 6.1%), vasomotor syndrome (2/33, 6.1%), post-operative gastrointestinal dysfunction (2/33, 6.1%), prevention of prolonged postoperative ileus (2/33, 6.1%), joint symptoms (1/33, 3.0%), and immunomodulation (1/33, 3.0%). The result of our systematic review suggested that the effectiveness of acupuncture in palliative care for cancer patients is promising, especially in reducing chemotherapy or radiotherapyinduced side effects and cancer pain. Acupuncture may be an appropriate adjunctive treatment for palliative care.Keywords：acupuncture;palliative care;cancer;tumor

Published：2021-08-27 - Abstract：To raise traditional medicine to a higher level of scientific research, a mathematical model has been proposed using symbolic notations and operators to describe several disease symptoms generally recognized in traditional medicine. Even though this model to a certain degree offers a mathematical approach to identify the relationships between yin-yang and the five viscera, it is not an efficient means of explaining the pathology in traditional medicine due to its use of superfluous notations and definitions. In this paper, we introduce two concise operators, a self-development operator and an action operator: the former describes the effect of a viscus in the unbalanced state on other viscera: the latter explains the engendering and restraining relationships between the two viscera. These tools are useful to elucidate the interactions among the states of the five viscera based on yin-yang and the five elements theory. Our mathematical model with these two operators facilitates description for the scheme of deficiency-excess of yin-yang in the five viscera. Accordingly, we have mathematically refined the existing results and shown clinical applications as well.Keywords：deficiency-excess mechanism;yin-yang theory;engendering and the restraining operators
