OBJECTIVE: To investigate the inhibitory effect of Celastrus orbiculatus extracts (COE) on the proliferation of lymphoma cells and the immune regulation ability on inflammation and thrombophilia in vivo. METHODS: The 38B9 lymphoma cells were treated with COE (160 µ g/mL) and CTX (25 µ mol/L). The apoptosis rate and cell cycle of each group were detected by flow cytometry. The secretion of inflammatory factors, including interleukin (IL)-6, IL-10, and tumor necrosis factor α (TNF-α), in cell supernatant was detected by enzyme-linked immunosorbent assay (ELISA). In vivo, BALB/c mice were subcutaneously injected with 38B9 lymphoma cells to establish lymphoma model. COE (3 mg·kg^-1·d^-1) and CTX (40 mg·kg^-1·d^-1) were administered to the model mice, respectively. The expression of plasma inflammatory factors (IL-6, IL-10 and TNF-α) and thrombus indexes, including D-dimer (D-D), von Willebrand factor (vWF) and tissue factor (TF), were detected by ELISA before tumor bearing (1 d), after tumor formation (14 d) and after intervention (21 d). PicoGreen dsDNA was used to detect the level of serum neutrophil extracellular traps (NETs). Flow cytometry was used to detect the expression of platelet activation marker calcium-dependent lectin-like receptor 2 (CLEC-2). The tumor growth and survival of mice were recorded. RESULTS: The 38B9 lymphoma cells were apoptotic after the intervention of COE and CTX. The ratio of G₂-M phase cells decreased in COE intervented cells compared with the control cells (P<0.05), and S phase cells decreased in CTX intervented cells (P<0.05). Also, the secretion level of IL-6 was significantly reduced after COE or CTX intervention (P<0.05), and IL-10 was significantly increased (P<0.05). Furthermore, the tumor mass was reduced, and the median survival time was longer in COE and CTX intervented tumor-bearing mice than in non-intervented mice. The significantly lower levels of TNF-α, IL-6, NETs, TF, DD and CLEC-2, as well as higher IL-10 were observed in COE and CTX treatment mice in comparision with the control mice (P<0.05). CONCLUSION COE has a mild and stable anti-tumor effect, which can reduce the secretion of inflammatory factors by lymphoma cells and regulate thrombophilic state caused by tumor inflammatory microenvironment.

This study aims to evaluate the quality consistency of Saposhnikoviae Radix based on carbohydrates, and explore the potential of carbohydrates as the internal quality control indicators of Saposhnikoviae Radix. The total polysaccharides were quantified by UV-Vis spectrophotometry and the molecular weight range of the polysaccharides was determined by high performance gel-permeation chromatography-evaporative light scattering detection(HPGPC-ELSD). The monosaccharides in polysaccharides and the free monosaccharides were quantified by high performance liquid chromatography-UV detection(HPLC-UV), and the oligosaccharides and fructose were quantified by high performance liquid chromatography-evaporative light scattering detection(HPLC-ELSD). The carbohydrate-based quality of Saposhnikoviae Radix was compared among 45 batches of commercial samples and 13 batches of self-collected samples. The results showed that the molecular weight distribution, monosaccharide composition, oligosaccharide, and free monosaccharide composition were similar in the 58 batches of samples. The average content of total polysaccharides, oligosaccharides, and total free monosaccharides in commercial samples were 39.66, 148.79, and 68.62 mg·g~(-1), respectively. The content showed significant differences among batches, with the highest differences of 3.51, 1.75, and 2.58 times, respectively. The RSD of the relative ratios of monosaccharides in the polysaccharides in commercial samples reached 28%-45%. The average content of total polysaccharides, oligosaccharides, and total free monosaccharides in self-collected samples were 68.07, 145.76, and 42.04 mg·g~(-1), respectively, with the inter-region differences of 2.88, 1.88, and 1.07 times, respectively. The RSD of the relative ratios of monosaccharides in polysaccharides in self-collected samples ranged from 8.2% to 59%. The total polysaccharides and total free monosaccharides in self-collected samples were 1.72 times higher and 1.63 times lower, respectively, than those in commercial samples. The content of oligosaccharides was similar between self-collected samples and commercial samples. To sum up, carbohydrates are one of the material bases for the internal quality consistency of Saposhnikoviae Radix. The qualitative characteristics of polysaccharides and the quantitative characteristics of polysaccharides and oligosaccharides are related to the origin of medicinal materials. Moreover, the quantitative characteristics of polysaccharides and free monosaccharides may be related to the storage conditions. Carbohydrates are potential indicators for the quality control of Saposhnikoviae Radix and deserve attention.

OBJECTIVE: This study aimed to investigate the regulation of histone-like nucleoid structuring protein (H-NS) on biofilm formation and cyclic diguanylate (c-di-GMP) synthesis in Vibrio parahaemolyticus RIMD2210633. METHODS: Regulatory mechanisms were analyzed by the combined utilization of crystal violet staining, quantification of c-di-GMP, quantitative real-time polymerase chain reaction, LacZ fusion, and electrophoretic-mobility shift assay. RESULTS: The deletion of hns enhanced the biofilm formation and intracellular c-di-GMP levels in V. parahaemolyticus RIMD2210633. H-NS can bind the upstream promoter-proximal DNA regions of scrA, scrG, VP0117, VPA0198, VPA1176, VP0699, and VP2979 to repress their transcription. These genes encode a group of proteins with GGDEF and/or EAL domains associated with c-di-GMP metabolism. CONCLUSION One of the mechanisms by which H-NS represses the biofilm formation by V. parahaemolyticus RIMD2210633 may be via repression of the production of intracellular c-di-GMP.

By referring to the standards and procedures of WHQ Handbook for Guideline Development, under the guidance of relevant laws, regulations, and technical documents, in line with the principle of "evidence-based, consensus-based, experience-based", and based on the best available evidences, fully combined with expert experience and patient preferences, we summarized eight clinical questions in this paper: can traditional Chinese medicine(TCM) treatment improve the clinical symptoms and the degree of dyspnea in patients with stable chronic obstructive pulmonary disease(COPD) Can TCM treatment reduce the number of exacerbations in patients with stable COPD? Can TCM treatment improve the exercise tolerance of patients with stable COPD? Can TCM treatment improve the quality of life of patients with stable COPD? Can TCM treatment delay the decline of lung function in patients with stable COPD? Can TCM treatment improve anxiety and depression in patients with stable COPD? Does the point application therapy benefit patients with stable COPD? Can non-pharmacological treatment benefit patients with stable COPD? Based on these eight clinical problems, the cha-racteristics of TCM itself, and actual clinical situation, the recommendations of TCM to treat the stable COPD were formed in this guideline, with intention to provide advice and guidance to clinicians in the use of TCM to treat stable COPD, to relieve symptoms, improve exercise tolerance, improve health status, prevent disease progression, prevent and treat exacerbations, and improve clinical efficacy. Due to the influence of the user's region, nationality, race and other factors, the implementation of this guideline should be based on the actual situations.

To systematically review the efficacy and safety of Liujunzi Decoction combined with Western medicine in the treatment of stable chronic obstructive pulmonary disease(COPD). Three English databases and four Chinese databases were systematically searched from the database establishment to April 1, 2020. We screened randomized controlled trial(RCT) according to the pre-determined inclusion and exclusion criteria, then extracted data. Methodological quality of included studies was assessed with Cochrane bias risk evaluation tool. Data were analyzed by using RevMan 5.3. A total of 401 articles were retrieved and finally 17 RCTs were included in this study, involving 1 447 patients, and the overall quality of the included studies was not high. Meta-analysis showed that, in reducing traditional Chinese medicine symptom score, Liujunzi Decoction combined with conventional Western medicine or Salmeterol Xinafoate and Fluticasone Propionate Powder for Inhalation was superior to conventional Western medicine or Salmeterol Xinafoate and Fluticasone Propionate Powder for Inhalation alone. In reducing the grade of modified medical research council(mMRC), Liujunzi Decoction combined with Salmeterol Xinafoate and Fluticasone Propionate Powder for Inhalation was superior to Salmeterol Xinafoate and Fluticasone Propionate Powder for Inhalation alone. In reducing COPD assessment test(CAT) score, Liujunzi Decoction combined with conventional Western medicine was superior to conventional Western medicine alone. In delaying the decline of forced expiratory volume in one second(FEV_1) or % in the expected value, Liujunzi Decoction combined with conventional Western medicine or Salmeterol Xinafoate and Fluticasone Propionate Powder for Inhalation was superior to conventional Western medicine or Salmeterol Xinafoate and Fluticasone Propionate Powder for Inhalation alone. In delaying the decline of ratio of FEV_1 to forced vital capacity(FEV_1/FVC), Liujunzi Decoction combined with conventional Western medicine was superior to conventional Western medicine alone, but there was no statistical difference between Liujunzi Decoction combined with Salmeterol Xinafoate and Fluticasone Propionate Powder for Inhalation and Salmeterol Xinafoate and Fluticasone Propionate Powder for Inhalation alone. In reducing acute exacerbation rate, there was no statistical difference between Liujunzi Decoction combined with Salmeterol Xinafoate and Fluticasone Propionate Powder for Inhalation and Salmeterol Xinafoate and Fluticasone Propionate Powder for Inhalation alone. On the other outcome measures of Liujunzi Decoction combined with other Western medicine, Meta-analysis could not be conducted and conclusions due to the inclusion of only one study. In terms of the occurrence of adverse reactions, some studies did not mention, so the safety of Liujunzi Decoction combined with Wes-tern medicine could not be determined in this paper. Due to the limitations of the quality and quantity of inclu-ded studies, the efficacy of Liujunzi Decoction combined with Western medicine for COPD still needs more high-quality studies for confirmation, and its safety needs to be further verified.

This article analyze acupoint selection and characteristics of plaster therapy for stable chronic obstructive pulmonary di-sease(COPD) by data mining. The CNKI, VIP, CBM, WanFang, PubMed, EMbase, Cochrane Library were retrieved for collecting clinical studies of plaster therapy for stable COPD. After literature screening, a total of 46 systematic reviews were included. Frequency statistics, cluster analysis, and Apriori correlation analysis were used to analyze the pattern and characteristics of plaster therapy for stable COPD. The result showed that the main acupoints for stable COPD were BL13, Dingchuan, CV22, BL23 and BL20. The acupoints used are mainly concentrated on the chest and back. The most frequently used meridian is the bladder meridian. Analysis of the acupoints yielded 27 correlation rules. And cluster analysis grouped the high frequency acupoints into 5 categories. The results of the study showed that the current choice of acupoints is rather concentrated. "Local acupuncture points" and "matching points with front and back" were the main acupoint selection rules. The choice of acupuncture points reflected the traditional Chinese medicine treatment principle of strengthening healthy Qi to eliminate pathogenic factor, treating both manifestation and root cause of disease, and preventing measure taken after the occurrence of disease.

Objective: To explore the risk predictive value of lipoprotein-associated phospholipase A2 (Lp-PLA2) on acute coronary syndrome(ACS) and to study the relationship between Lp-PLA2 and the severity of coronary stenosis in ACS patients. Methods:A total of 155 ACS patients admitted in our hospital were enrolled. The patient were divided into 2 groups:AMI (acute myocardial infarction) group, n=49 and UA (unstable angina)group, n=106; in addition, there was a Control group, n=44 subjects with normal coronary angiography (CAG).Blood levels of Lp-PLA2 were examined, CAG was conducted and GRACE score, SYNTAX score,Gensini score were calculated. Based on Grace score, ACS patients were divided into 3 subgroups: Low risk subgroup, Grace score≤108, Mid risk subgroup,Grace score 109-140 and High risk subgroup,Grace score≥140.The above parameters were comparedamong different groups. Results: Compared with UA group and Control group, AMI group had increased blood level of Lp-PLA2, P<0.05. Compared with Low risk subgroup, High risk subgroup had much higher Lp-PLA2, P<0.05. Correlation analysis showed that Lp-PLA2 level was positively related to Gracescore (r=0.301, P<0.001). By SYNTAX score and Gensini score evaluation,Lp-PLA2 levels were similar among different subgroups. Conclusion:Blood level of Lp-PLA2 had certain risk predictive value in ACS patients; while it was not related to the severity of coronary stenosis.
