ResultAfter treatment， the total effective rate of the observation group ［95.35% （41/43）］ was significantly better than that of the control group ［79.07% （34/43）］， and the difference was statistically significant （χ2=5.108， P<0.05）. After treatment， the scores of the primary and secondary TCM syndromes in the observation group and the control group were significantly decreased （P<0.05）. After treatment， the scores of primary and secondary TCM syndromes in the observation group were significantly lower than those in the control group （P<0.05）. After treatment， the pathological scores of gastric mucosa atrophy， activity， chronic inflammation， intestinal metaplasia， and dysplasia were significantly lower in the observation group and control group （P<0.05）. After treatment， the pathological scores of gastric mucosa atrophy， activity， chronic inflammation， intestinal metaplasia， and dysplasia in the observation group were significantly lower than those in the control group （P<0.05）. After treatment， the Hp conversion rate in the observation group was significantly increased compared with the control group （P<0.05）. After treatment， the levels of inflammatory indicators NLR and IL-1β in the observation group and control group were significantly lower （P<0.05）， and the levels of inflammatory indicators NLR and IL-1β in the observation group were significantly lower than those in the control group （P<0.05）. After treatment， the levels of PGI and PGⅠ/PGⅡ in the observation group and control group were significantly higher （P<0.05）， and the levels of PGI and PGⅠ/PGⅡ in the observation group were significantly higher than those in the control group （P<0.05）. After treatment， the G-17 level of the observation group and the control group was different at different time points （P<0.05）， and the G-17 level of the observation group was higher at different time points than that of the control group （P<0.05）. The G-17 level of the observation group had an increasing trend compared with the control group （P<0.05）. There was no significant difference in the risk of adverse reactions between the two groups. ConclusionThe combination of Jianpi Huoxue prescription and acupuncture can effectively alleviate symptoms， increase Hp negative conversion rate， inhibit inflammation， and regulate PG and G-17 levels in CAG patients， thus controlling or even reversing gastric mucosal atrophy and reducing the probability of its progression to gastric cancer.

Integrated pharmacokinetics and pharmacometabolomics to reveal the synergistic mechanism of a multicomponent Chinese patent medicine, Mailuo Shutong pills against thromboangiitis obliterans.

BACKGROUND: Mailuo Shutong Pills (MLST) have displayed pharmacological activity against thromboangiitis obliterans (TAO). However, the active ingredients and therapeutic mechanism of MLST against TAO remained to be further clarified. PURPOSE: The aim of this study was to explore the active components of MLST and their synergistic mechanism against TAO by integrating pharmacokinetics (PK) and pharmacometabolomics (PM). METHODS: TAO model rats were established by sodium laurate solution. Firstly, the efficacy of MLST was evaluated by gangrene score, blood flow velocity, and hematoxylin-eosin (H&E) staining. Secondly, PK research was conducted on bioavailable components to characterize their dynamic behaviors under TAO. Thirdly, multiple plasma and urine metabolic biomarkers for sodium laurate-induced TAO rats were found by untargeted metabolomics, and then variations in TAO-altered metabolites following MLST treatment were analyzed utilizing multivariate and bioinformatic analysis. Additionally, metabolic pathway analysis was performed using MetaboAnalyst. Finally, the dynamic link between absorbed MLST-compounds and TAO-associated endogenous metabolites was established by correlation analysis. RESULTS: MLST significantly alleviated gangrene symptoms by improving the infiltration of inflammatory cells and blood supply in TAO rats. Significant differences in metabolic profiles were found in 17 differential metabolites in plasma and 24 in urine between Sham and TAO rats. The 10 bioavailable MLST-compounds, such as chlorogenic acid and paeoniflorin, showed positive or negative correlations with various TAO-altered metabolites related to glutamate metabolism, histidine metabolism, arachidonic acid metabolism and so on. CONCLUSION: This study originally investigated the dynamic interaction between MLST and the biosystem, providing unique insight for disclosing the active components of MLST and their synergistic mechanisms against TAO, which also shed light on new therapeutic targets for TAO and treatment.

Protective effects and mechanisms of Lizhong decoction against non-alcoholic fatty liver disease in a rat model.

OBJECTIVE: To investigate the protective effects and molecular mechanisms of Lizhong decoction (, LZD) against non-alcoholic fatty liver disease (NAFLD). METHODS: Male Wistar rats were fed a high-fat diet for four weeks to induce NAFLD, and were administered LZD by gavage for four weeks. Potential therapeutic targets for NAFLD were analyzed using network pharmacology. Liver pathology was evaluated using Oil Red O and hematoxylin-eosin staining. Furthermore, mitochondrial function, lipid metabolism, oxidative stress, and inflammatory response were examined. RESULTS: Rats with NAFLD exhibited high levels of hepatic damage and cholesterol deposition. Moreover, apoptosis was increased, superoxide dismutase and glutathione content were reduced, malondialdehyde content was increased, and the protein expression of inflammatory cytokines and p-c-Jun N-terminal kinase was increased. The LZD treatment ameliorated mitochondrial dysfunction, reduced liver damage, inhibited oxidative stress and inflammatory response, upregulated peroxisome proliferator-activated receptor (PPAR)-γ expression, and suppressed dipeptidyl peptidase 4 (DPP4) expression in the liver. CONCLUSION: It was found that LZD alleviates NAFLD by activating PPAR-γ and inhibiting DPP4.

Identifying quality markers of Mailuoshutong pill against thromboangiitis obliterans based on chinmedomics strategy.

BACKGROUND: Mailuoshutong pill (MLSTP) is a traditional Chinese medicine (TCM) for the treatment of Thromboangiitis obliterans (TAO, Buerger's disease) which is a segmental non-atherosclerotic inflammatory occlusive disorder. However, the mechanism and quality standards of MLSTP have not been sufficiently studied. PURPOSE: This work aims to investigate the potential mechanisms and quality markers (Q-markers) of MLSTP treating TAO based on the chinmedomics strategy. METHODS: The therapeutical effect of MLSTP on TAO rats was evaluated by changes in body weight and clinical score, regional blood flow velocity and perfused blood vessel distribution, hematoxylin-eosin (H&E) staining, serum metabolic profile. Moreover, both endogenous metabolites and exogenous components were simultaneously detected in serum based on ultra-high performance liquid chromatography coupled with a Q Exactive hybrid quadrupole-orbitrap high resolution mass spectrometry (UHPLC-Q-Orbitrap HRMS), and multivariate analysis was applied to identify the biomarkers, as well as the dynamic changes of metabolites were observed to explore the mechanism of action of MLSTP. In addition, the pharmacodynamic material basis were identified by correlation analysis between biomarkers and absorbed constituents. Finally, the Q-markers of MLSTP were determined according to the screening principles of Q-marker and validated the measurability. RESULTS: MLSTP treatment alleviated disease severity of TAO, reduced inflammatory infiltration, and ameliorated vascular function. 26 potential biomarkers associated with glutamate metabolism, linoleic acid metabolism, arachidonic acid metabolism and so on were identified. Besides, 27 prototypical components were identified in serum, 16 of which were highly correlated with efficacy and could serve as the pharmacodynamic material basis of MLSTP against TAO. In addition, 7 compounds, namely, sweroside, chlorogenic acid, calycosin-7-glucoside, formononetin, paeoniflorin, liquiritigenin and 3-butylidenephthalide, were considered as potential Q-markers of MLSTP. Ultimately, the measurability of the seven Q-markers was validated by rapid identifcation and quantifcation. CONCLUSION: This study successfully clarified the therapeutic effect and Q-markers of MLSTP by chinmedomics strategy, which is of great significance for the establishment of quality standards. Furthermore, it provides a certain reference for the screening of Q-markers in TCM prescriptions.

Successfully treated recalcitrant atopic eczema with acupoint autohemotherapy: A case report and hypothesized mechanism of the therapy / 中西医结合学报

Acupoint autohemotherapy at bilateral Zusanli (ST36) and Xuehai (SP10) was used to treat a 26-year-old female patient who had suffered from recalcitrant atopic eczema (AE) for five years. The treatment was applied at a frequency of once per week for the first month, followed by a three-month period of once every other week. At the end of treatment, the patient's AE symptoms were entirely resolved, and by the end of a six-month follow-up her immunoglobulin E level had returned to the normal range. Further, there was no relapse of AE symptoms during the six-month follow-up. Therefore, we hypothesized that after the repeated treatments the local inflammatory reaction induced by autologous blood injection triggered a local immune response, followed by a systemic immune response after the repeated treatment, finally leading to the anti-inflammation and immunomodulation effects. This case suggests that acupoint autohemotherapy could be used as an effective complementary treatment for recalcitrant AE, especially in cases where other treatments have failed. Further comparative studies are needed to corroborate the value and mechanisms of this therapy.

Relationship Between Syndrome Elements and Therapy of Ischemic Stroke Based on Scale Hierarchy and Principal Component Analysis / 中国实验方剂学杂志

Objective:To study the distribution of ischemic stroke treatment with data mining technology and evaluate its clinical efficacy. Method:China National Knowledge Infrastructure Database（CNKI），China Science and Technology Reader's Digest Database（VIP），Wanfang Data，Chinese Biomedical Literature Database（Sino Med）were retrieved from January 1978 to December 2018. The clinical observation and study literatures on the treatment of ischemic stroke with the combination of traditional Chinese medicine and Western medicine were retrieved in the four databases. After standardized and hierarchical collection and processing of all syndromes，treatment methods，prescriptions and other information in the literatures，a database of syndrome elements and treatment of ischemic stroke was established. Syndrome factors and treatment methods were analyzed by scale evaluation and hierarchical classification methods. Kendall's tau-b correlation analysis，principal component analysis and other statistical methods were used to describe the correlation and distribution of syndrome factors and treatment methods of ischemic stroke. Result:The results of heterogeneity analysis showed that the included literatures were homogeneous and could be combined with subsequent statistics. A total of 450 syndromes and treatment methods were included in this study，and 1 287 single syndrome elements and 1 562 single treatment methods were obtained after unified and standardized splitting. Besides the corresponding syndrome elements and treatment methods，phlegm-dampness-invigorating Qi（-0.52） and Qi deficiency-invigorating Qi（-0.56） were also highly correlated. The study team represented the importance of syndrome and treatment elements with class Ⅰ，Ⅱ，Ⅲ from high to low. Qi deficiency，blood stasis and fire heat，phlegm，viscera excess were class Ⅰ syndrome elements；Yin deficiency，endogenous wind were class Ⅱ syndrome elements；Yin deficiency and Yang deficiency were class Ⅲ syndrome elements；Removing phlegm dampness，clearing heat，clearing the hollow viscera and extinguishing wind，promoting blood circulation to remove blood stasis，tonifying Qi were class Ⅰ treatment of ischemic stroke，and removing phlegm dampness，clearing heat，clearing the hollow viscera were more likely to appear simultaneously； and extinguishing wind，activating blood circulation and removing blood stasis，and benefiting Qi were more likely to appear simultaneously. Nourishing Yin and regulating Qi were class Ⅱ therapies of ischemic stroke，which were highly correlated and often appear simultaneously. Inducing resuscitation，tonifying Yang and dredging collaterals were class Ⅲ，Ⅳ，Ⅴ therapies. Conclusion:Qi deficiency，blood stasis，phlegm dampness，fire heat and viscera excess were the main syndromes of ischemic stroke，while Qi deficiency and blood stasis，phlegm heat and viscera excess were the main syndromes. Eliminating phlegm and dampness，clearing heat，clearing the hollow viscera，promoting blood circulation and removing blood stasis，extinguishing wind and benefiting Qi were the main therapies for the treatment of ischemic stroke. In clinical treatment for ischemic stroke，the therapies for relieving phlegm and dampness，clearing heat and relieving organs are often used in combination，and the therapies for promoting blood circulation and removing blood stasis were often used in combination with the therapies for invigorating Qi and extinguishing wind for the synergistic effect.

OAS models were made in the latter three groups by intragastrical administration of tripterygium glycosides at 40 mg per kg of the body weight per day, and meanwhile the animals in the low- and high-dose QLP groups were treated with QLP at 1.62 and 3.24 g per kg of the body weight per day, respectively, while those in the OAS model group with normal saline, all for 30 consecutive days. Then all the rats were executed for obtaining the testis weight, testis viscera index, epididymal sperm concentration and motility, reproductive hormone levels, and antioxidation indexes and observation of the histomorphological changes of the testis tissue by HE staining.@*RESULTS@#After 30 days of intervention, the low- and high-dose QLP groups, as compared with the OAS model controls, showed significantly improved epididymal sperm concentration (［14.57 ± 3.95］ and ［39.71 ± 11.31］ vs ［4.71 ± 1.25］ ×10⁶/ml, P <0.05) and motility (［3.71 ± 1.11］ and ［4.29 ± 1.80］ vs ［0.57 ± 0.53］%, P <0.05), increased levels of sex hormone binding globulin (SHBG) (［94.83 ± 11.17］ and ［88.05 ± 9.21］ vs ［56.74 ± 8.29］ nmol/L, P <0.05) and free testosterone (FT) (［27.27 ± 3.63］ and ［32.80 ± 2.51］ vs ［22.81 ± 2.75］ nmol/L, P <0.05), decreased level of follicle-stimulating hormone (FSH) (［1.49 ± 0.62］ and ［1.12 ± 0.83］ vs ［1.71 ± 0.52］ mIU/ml, P <0.05), but no significant change in the total testosterone (TT) level. Meanwhile, the level of superoxide dismutase (SOD) was markedly elevated in the low- and high-dose QLP groups in comparison with the OAS model control group (［277.14 ± 15.84］ and ［299.60 ± 20.83］ vs ［250.04 ± 31.06］ U/ml, P <0.05) while that of reactive oxygen species (ROS) remarkably reduced (［397.61 ± 62.71］ and ［376.84 ± 67.14］ vs ［552.20 ± 58.07］ IU/ml, P <0.05). HE staining showed that QLP intervention significantly increased the layers and quantity of spermatogenic cells in the testicular seminiferous tubules of the OAS rats.@*CONCLUSIONS@#QLP can effectively protect the reproductive system of oligoasthenospermia rats by raising sperm quality, elevating reproductive hormone levels, reducing oxidative stress injury, and improving histomorphology of the testis.

Acupuncture combined with moxibustion plaster for nerve-root type cervical spondylosis / 中国针灸

<p><b>OBJECTIVE</b>To compare the clinical efficacy differences between acupuncture combined with moxi-bustion plaster and electroacupuncture (EA) for nerve-root type cervical spondylosis.</p><p><b>METHODS</b>A total of 60 casesof nerve-root type cervical spondylosis were randomly divided into a plaster group and an EA group, 30 cases ineach one. Patients in the plaster group were treated with regular acupuncture at Jiaji(EX-B 2) points and ashipoints, combined with moxibustion plaster at Gaohuang (BL 43); patients in the EA group were treated with EAat identical acupoints as plaster group. The treatment was given once a day, and 5 days were taken as one course;there was an interval of 2 days between courses and totally 2 courses were performed. The pain questionnaires andquantitative score of signs and symptoms were observed before and after treatment in the two groups. The clinicalefficacy of the two groups was compared.</p><p><b>RESULTS</b>The total effective rate was 96. 7% (29/30) in the plastergroup, which was not significantly different from 93. 3% (28/30) in the EA group (P>0. 05). After treatment,PRI, VAS and PPI were all reduced in the two groups (all P<C. 01), which were also significantly different be-tween the two groups (all P<0. 05). The quantitative score of each sign and symptom was increased after treat-ment in the two groups (all P<0. 01). Compared with the EA group, the work and life ability, function, feelingand strength of hand were increased in the plaster groups (all P<. 05). Pain score of neck and shoulder aftertreatment in the EA group was higher than the plaster group (all P<0. 05).</p><p><b>CONCLUSION</b>Acupuncture combinedwith moxibustion plaster and EA both have superior clinical efficacy for nerve-root type cervical spondylosis; EA issuperior to acupuncture combined with moxibustion plaster on relieving pain, while acupuncture combined withmoxibustion plaster is superior to EA on improving life quality, muscle strength and feeling.</p>

Pollen viability, stigma receptivity and fruiting characteristics of botanical origin of Jinxianlian / 中国中药杂志

The viability and life span of pollen were evaluated by TTC (2,3,5-triphenyl tetrazlium chloride) and the peroxidase solution, the stigma receptivity were estimated by benzidine-H2O2 method and the fruiting characteristics were investigated. The results showed that (1) Anoectochilus roxburghii and A. formosanus appeared the same up-and-down trend of the pollen viability, increased and then decreased. The storage temperature and storage time had significant impact on the pollen viability. With the extension of storage time, the pollen activity decreased. 4 degrees C refrigerator storage may be extended the pollen vitality. (2) The stigma had receptivity in 1st day and reached the highest level in the 4th day after blooming. A. roxburghii lost receptivity in the 8th day while A. formosanus lost receptivity in the 10th day after blooming. (3) The different pollination had significant impact on seed setting rate. The seed setting rate of artificial cross-pollination was higher than that of the artificial self-pollination. Collecting pollen in the 3rd day and carrying out artificial cross-pollination in the 4th day after blooming can significantly improve seed setting rate. The results provided technical assurance for A. roxburghii and A. formosanus breeding of new varieties and seed breeding.

The Efficacy and Safety of Wenxin Keli in Patients with Frequent Premature Ventricular Contractions: A Randomized, Double-blind, Placebo-controlled, Parallel-group, Multicenter Trial / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Premature ventricular contractions (PVCs) are common in the general population, and frequent PVCs may result in the poor quality of life or even the damage of cardiac function. We examined the efficacy and safety of a traditional Chinese medicine Wenxin Keli for the treatment of frequent PVCs among a relatively large Chinese cohort.</p><p><b>METHODS</b>We performed a randomized, double-blind, placebo-controlled, parallel-group, multicenter trial. A total of 1200 eligible participants were randomly assigned in a ratio of 1:1 to receive Wenxin Keli or the placebo for 4 weeks. The primary and secondary endpoint was the change of PVC numbers and PVC-related symptoms after a 4-week treatment compared with baseline, respectively. In addition, vital signs, laboratory values, and electrocardiographic parameters were assessed in a safety analysis.</p><p><b>RESULTS</b>At the initial evaluation, no significant differences in the baseline characteristics were observed between the Wenxin Keli group and the placebo group. A smaller number of PVCs was observed after the 4-week treatment than at baseline, in both the Wenxin Keli group (5686 ± 5940 vs. 15,138 ± 7597 beats/d, P < 0.001) and the placebo group (10,592 ± 8009 vs. 14,529 ± 5929 beats/d, P < 0.001); moreover, the Wenxin Keli group demonstrated a significantli greater reduction in the frequency of PVCs than the placebo group (P < 0.001). In a full analysis set, patients in the Wenxin Keli group exhibited significantly higher total effective responses in the reduction of PVCs compared to those in the placebo group (83.8% vs. 43.5%,P < 0.001). The per-protocol analysis yielded similar results (83.0% vs. 39.3%,P < 0.001). Treatment with Wenxin Keli also demonstrated superior performance compared to the placebo with respect to PVC-related symptoms. No severe adverse effects attributable to Wenxin Keli were reported.</p><p><b>CONCLUSIONS</b>Wenxin Keli treatment effectively reduced the overall number of PVCs and alleviated PVC-related symptoms in patients without structural heart diseases and had no severe side effects.</p>
