Treatment of Psoriasis Vulgaris with Medicated Thread Moxibustion of Zhuang Medicine: A Multicenter Randomized, Parallel Controlled Trial / 中国结合医学杂志

OBJECTIVE@#To explore the efficacy and safety of Zhuang medicine medicated thread moxibustion (ZMTM) on psoriasis vulgaris.@*METHODS@#A multicenter, randomized, parallel controlled clinical trial was designed. A total of 241 outpatients with psoriasis vulgaris were randomly divided into a control group (120 cases) and a treatment group (121 cases) using a central block randomization from June 2015 to May 2018. The control group was treated with Western medicines alone including pidotimod dispersible tablets, vitamin B compound tablets, and compound cod liver oil-zinc oxide ointment. The treatment group was treated with ZMTM every 2 days combined with Western medicines. The two groups received continuous intervention for 30 days. The primary outcome was Psoriasis Area and Severity Index (PASI), and the secondary outcomes included Itch Rating Scale, Dermatology Quality of Life Index (DLQI), Hamilton Anxiety Rating Scale (HAMA), as well as PASI response rate. Meanwhile, adverse events were evaluated during the whole clinical trial. Follow-up was carried out 30 days after treatment.@*RESULTS@#There were 5 cases of shedding in this trial. In intention-to-treat analysis, 236 cases were included and each group contained 118 cases. On the 30th and 60th days, PASI scores of patients in each group were significantly lower than that at baseline (P<0.01) and the PASI score reduction of the treatment group was greater than that of the control group (P<0.01). Itch Rating Scale, DLQI, and HAMA scale were decreased in both groups after treatment, and the treatment group showed a better therapeutic effect (P<0.01). The response rates of PASI 50 and 75 were significantly higher than those in the control group [81.4% (96/118), 43.2% (51/118) vs. 41.5% (49/118), 11.0% (13/118), respectively, P<0.05]. During follow-up, the improvements in scores of PASI, Itch Rating Scale, DLQI, and HAMA of the treatment group were significantly greater than those of the control group (P<0.01). The response rates of PASI 50 and 75 in the treatment group were significantly higher than those in the control group, respectively (both P<0.05). No obvious adverse reaction was found in either group.@*CONCLUSION@#ZMTM combined with Western medicines showed a better therapeutic effect in the treatment of psoriasis vulgaris without obvious adverse reaction.

Effect and Safety of Acupuncture for Type 2 Diabetes Mellitus: A Systematic Review and Meta-analysis of 21 Randomised Controlled Trials / 中国结合医学杂志

OBJECTIVE@#To evaluate the effects of acupuncture on hypoglycaemic outcomes in type 2 diabetes mellitus (T2DM).@*METHODS@#PubMed, Embase, Cochrane Library, and ClinicalTrials.gov were searched from inception up to July 2020, to identify randomised controlled trials (RCTs) that enrolled patients with T2DM and compared acupuncture combined with antidiabetic drugs to antidiabetic drugs alone. The primary outcomes were haemoglobin A1c (HbA1c) and fasting blood glucose (FBG). The secondary outcomes included 2-h blood glucose (2hBG), fasting insulin (FINS), homeostatic model assessment for insulin resistance (HOMA-IR), and acupuncture-related adverse events. Mean difference (MD) and 95% confidence interval (CI) were used as the effect measure in the meta-analysis. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation tool.@*RESULTS@#Twenty-one RCTs (n=1,188) were included. The meta-analytic results showed that the acupuncture group had greater reductions in FBG (MD -6.46 mg/dL, 95% CI -11.95 to -0.98; moderate-quality evidence) and HOMA-IR (MD -1.23, 95% CI -2.16 to -0.31; low-quality evidence), but comparable changes in HbA1c (MD -0.39%, 95% CI -0.84 to 1.61; very-low-quality evidence), 2hBG (MD -4.99 mg/dL, 95% CI -20.74 to 10.76; low-quality evidence), and FINS (MD -1.32 µIU/mL, 95% CI -3.76 to 1.12; low-quality evidence). No data on the incidence of diabetic complications were found. All acupuncture-related adverse events reported were mild.@*CONCLUSIONS@#The current evidence suggests that acupuncture, as a complementary therapy to antidiabetic drugs, has a small but statistically significant effect on decreasing FBG and improving insulin resistance. The effects of acupuncture on HbA1c, 2hBG, and FINS remain uncertain. Acupuncture is generally safe in patients with mild diabetes. More evidence for the long-term effects of acupuncture on T2DM is needed. (Trial registration No. CRD42018115639).

A combined quality evaluation method that integrates chemical constituents, appearance traits and origins of raw Rehmanniae Radix pieces / 中国天然药物

The quality control of Chinese herbal medicine is a current challenge for the internationalization of traditional Chinese medicine. Traditional quality evaluation methods lack quantitative analysis, while modern quality evaluation methods ignore the origins and appearance traits. Therefore, an integrated quality evaluation method is urgent in need. Raw Rehmanniae Radix (RRR) is commonly used in Chinese herbal medicine. At present, much attention has been drwan towards its quality control, which however is limited by the existing quality evaluation methods. The present study was designed to establish a comprehensive and practical method for the quality evaluation and control of RRR pieces based on its chemical constituents, appearance traits and origins. Thirty-three batches of RRR pieces were collected from six provinces, while high-performance liquid chromatography (HPLC) was applied to determine the following five constituents, including catalpol, rehmannioside A, rehmannioside D, leonuride and verbascoside in RRR pieces. Their appearance traits were quantitatively observed. Furthermore, correlation analysis, principal components analysis (PCA), cluster analysis and t-test were performed to evaluate the qualities of RRR pieces. These batches of RRR pieces were divided into three categories: samples from Henan province, samples from Shandong and Shanxi provinces, and those from other provinces. Furthermore, the chemical constituents and appearance traits of RRR pieces were significantly different from diverse origins. The combined method of chemical contituents, appearance traits and origins can distinguish RRR pieces with different qualities, which provides basic reference for the quality control of Chinese herbal medicine.

Meanwhile, 2 similar cases in the previous literature were also discussed.@*RESULTS@#The bone marrow examination indicated that the patient with B-cell acute lymphocytic leukemia. The lymph node biopsy showed that the patient was T lymphoblastic/myeloid lymphoma. The 8p11 abnormality was found by the examination of bone marrow chromosomes. The RT-PCR examination showed that the BCR-ABL fused gene was negtive. The FGFR1 breakage was found by using the FISH with FGFR1 probe in lymph node. The Mutation of FMNL3, NBPF1 and RUNX1 genes was found by using the whole exome sequencing. The patient received allo-HSCT under CR2. By the follow-up till to September 2019, the patient survived without the above-mentioned disease.@*CONCLUSION@#EMS manifest as neoplasms involving T-lineage, B-lineage, and myeloid-lineage simultaneously is extremely rare. Although the FGFR1 gene-targeted therapy can be conducted, allo-HSCT should be actively considered.

Effects of Huatan Jiangzhuo decoction on diet-induced hyperlipidemia and gene expressions in rats / 中国天然药物

Huatan Jiangzhuo decoction (HJD) is a combination of six traditional Chinese medicines that were used for lipid metabolism-related disorders, but its efficacy and underlying mechanisms have not been explored by modern research strategies. This study aimed to investigate the therapeutic role of HJD in determining the transcriptome level. Hyperlipidemia model was established by feeding Sprague-Dawley rats with high-fat diet. Differentially expressed genes (DEGs) were detected by high-through transcriptome sequencing, followed by gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. The total cholesterol (TC) and triglyceride (TG) levels in hyperlipidemia model rats were significantly increased, whereas high-density lipoprotein (HDL) concentration decreased when compared to normal rats, and HJD significantly downregulated TC concentrations and liver coefficient in the hyperlipidemia rats. Histology staining showed that HDJ greatly recovered the lipid accumulation in rat hepatic stellate cells and aortic arch vascular wall thickness of hyperlipidemia rats. One thousand nine hundred and thirty-six DEGs were identified in the HJD-treated hyperlipidemia rats, which were associated with various biological processes and signaling pathways such as peroxisome proliferator-activated receptors, AMP-activated Protein Kinase , and insulin signaling pathways. Quantitative reverse transcription-polymerase chain reaction further confirmed the downregulated expression of cholesterol 7-α-hydroxylase(CYP7A1), liver orphan receptor(LXRα),peroxisome proliferator-activated receptor gamma(PPARγ),andSterol Response Element-Binding Protein 1c(SREBP1c) genes in hyperlipidemia rats treated with HJD. Our data first elucidated the gene expression profile of high-fat diet-induced hyperlipidemia in rats after HJD treatment, and lipid metabolism-related genes (CYP7A1, LXRα, PPARγ, and SREBP1c) may be potentially biomarkers for HJD-alleviated hyperlipidemia.

Effect of Thick-Needle Therapy in Patients with Bell's Palsy at Recovery Stage: A Multi-center Randomized Controlled Trial / 中国结合医学杂志

OBJECTIVE@#To compare the clinical effects of thick-needle therapy (TNT) and acupuncture therapy (AT) on patients with Bell's palsy (BP) at the recovery stage.@*METHODS@#A total of 146 eligible participants from 3 hospitals in China were randomized into the TNT group (73 cases) and the AT group (73 cases) using a central randomization. Both groups received Western medicine thrice a day for 4 weeks. Moreover, patients in the TNT group received subcutaneous insertion of a thick needle into Shendao (GV 11) acupoint, while patients in the AT group received AT at acupoints of Cuanzhu (BL 2), Yangbai (GB 14), Dicang (ST 4), Xiaguan (ST 7), Jiache (ST 6), Yingxiang (LI 20) and Hegu (LI 4), 4 times a week, for 4 weeks. Both groups received 2 follow-up visits, which were arranged at 1 month and 3 months after treatment, respectively. The primary outcome measure was House-Brackmann Facial Nerve Grading System (HBFNGS) grade. And the clinical recovery rates of both groups were evaluated according to the HBFNGS grades after treatment. The secondary outcome measures included the facial disability index (FDI) and electroneurogram (EnoG). The adverse events were observed and recorded in both groups.@*RESULTS@#Three cases withdrew from the trial, 2 in the TNT group and 1 in the AT group. There was no signifificant difference in the clinical recovery rates between the TNT and AT groups after 4-week treatment [40.85% (29/71) vs. 34.72% (25/72), P>0.05]. At the 2nd follow-up visit, more patients in the TNT group showed reduced HBFNGS grades than those in the AT group (P0.05).@*CONCLUSION@#The clinical effect of TNT was equivalent to that of AT in patients with BP at recovery stage, while the post-treatment effect of TNT was superior to that of AT.

OBJECTIVE@#To calculate the imbalance degree (IBD) of left-right meridian (IBD-LRM), IBD of exterior-interior meridian (IBD-EIM) and IBD of hand-foot meridians (IBD-HFM) of impedance in extracellular fluid of cells in twelve meridians of healthy subjects, so as to provide foundation for meridian diagnosis.@*METHODS@#A total of 31 healthy volunteers were enrolled and bioelectrical impedance spectroscopy (BIS) was applied. The constant current (from 1 to 100 kHz, 200 μA) was connected into the bilateral twelve meridians through two excitation electrodes with a distance of 10 cm. Two measuring electrodes, with an interval of 5 cm, were set in between the two excitation electrodes to collect the voltage amplitude and phase. The Cole-Cole curve fitting was used to calculate the impedance of extracellular fluid of cells in the twelve meridians; the IBD-LRM, IBD-EIM and IBD-HFM as well as their absolute values were calculated.@*RESULTS@#The impedance of extracellular fluid in the left side was higher than that in right side in the large intestine meridian, the small intestine meridian and the bladder meridian (<0.05, <0.01). The mean value of IBD-LRM of extracellular fluid was (4.0±1.4) %; the mean value of absolute value of IBD-LRM was (15.0±1.1) %; the maximum absolute value of IBD-LRM was the bladder meridian. The mean value of IBD-EIM was (3.3±1.0) %; the mean value of absolute value of IBD-EIM was (17.9±1.6) %; the maximum absolute value of IBD-EIM was the bladder meridian and the kidney meridian. The impedance of extracellular fluid of hand meridian, hand meridian and hand meridian were lower than those of foot meridians. The mean value of IBD-HFM was (-2.6±1.1) %; the mean value of absolute value of IBD-HFM was (19.7±1.7) %; the maximum absolute value of IBD-HFM was meridian; the imbalance of meridians was greater than meridians. There were significant differences in impedance of extracellular fluid between left and right and between hands and feet (<0.05, <0.01).@*CONCLUSION@#The extracellular fluid of left-right meridians of healthy subjects is different, but the absolute value of IBD is low; the mean value of exterior meridian and interior meridian is very close, and the absolute value of IBD is medium; the impedance of the foot meridians are greater than the hand meridians, and the absolute value of IBD is relatively high.

The aim of this paper was to systematically evaluate the toxicity-reducing effect of Tripterygium-licorice in animal experiments,and also to provide evidence for basic research on the toxicity reduction of Tripterygium wilfordii. The PubMed,EMbase,Web of Science,CBM,CNKI and Wan Fang Databases from their establishment to August 31 th,2018 were searched. Two independent reviewers screened the papers,extracted the data,assessed the risk of bias using SYRCLE assessment tool and conducted Meta-analysis with Rev Man 5. 3 software. A total of 10 papers involving 31 studies were finally included,15 studies of which were used for Meta-analysis. Four studies were included for chronic hepatotoxicity animal model. In experimental group( 34 animals),Tripterygium was administered at dose of 0. 09-0. 1 mg·kg-1·d-1,and glycyrrhizic acid was administered at dose of 90-100 mg·kg-1,both for 2 weeks; in control group( 34 animals),glycyrrhizic acid was replaced with equal volume of normal saline. Eleven studies were included for acute hepatotoxicity animal model. In experimental group( 66 animals),glycyrrhizic acid was administered at dose of 75-480 mg·kg-1 for 7 days,then glycyrrhizic acid was stopped,and Tripterygium began to be administered at dose of 0. 6-1. 0 mg·kg-1 per 24 h or 48 h for a total of 1-2 times; in control group( 66 animals),glycyrrhizic acid was replaced with equal volume of normal saline or corresponding solvent. The results of Meta-analysis showed that in both chronic hepatotoxicity animal model and acute hepatotoxicity animal model,the transaminase levels in the experimental group were lower than those in the control group( P < 0. 05). Subgroup analysis of acute hepatotoxicity animal model showed that the transaminase levels in the experimental group were lower than those in the control group for every subgroup except " glycyrrhizic acid 75 mg·kg-1" subgroup. However,in terms of the mean difference( MD) and confidence interval( CI),there was no significant difference in transaminase decline between each subgroup. Low dose of glycyrrhizic acid( 90-100 mg·kg-1) has a toxicity-reduction effect on chronic hepatotoxicity induced by tripterygium( 0. 09-0. 10 mg·kg-1). Middle and high doses of glycyrrhizic acid( 120-480 mg·kg-1) have a toxicity-reduction effect on acute hepatotoxicity induced by tripterygium( 0. 6-1. 0 mg·kg-1),but with no significant dose-effect relationship.

Discussion on the classification of acupoints / 中国针灸

This paper discusses the existing classification of acupoints and puts forward a new classification method of acupoints. Through the definition of 3 kinds of acupoints and the analysis of the original meaning of points, it is pointed out that the existing classification of acupoints has overlapping among different categories. The acupoints are reclassified based on the characteristics of acupoints in reflecting and treating disease as well as the application of acupoints in clinic. Acupoints can be divided into traditional acupoints and modern holographic acupoints, among which traditional acupoints can be divided into meridian system points and extra points. According to their structure and function features, meridian system points can be divided into meridian points, collateral points, meridian-muscles points and cutaneous region points. The new classification method of acupoints highlights the importance of channel-collateral theory in acupuncture clinic and the feature of acupuncture in the diagnosis and treatment of disease.

Effects of Chinese traditional medicine-selected recipe Q0409 on ability of learning and memory in SAM-P/8 mice / 中国病理生理杂志

AIM:To investigate the effects of Chinese traditional medicine-selected recipe Q0409 on the ability of learning and memory in SAM-P/8 mice. METHODS:Total 91 mice (4-month-old SAM-P/8 mice, SAM-R/1 mice and Kunming mice) were used in the study, in which the male and female animals were labeled separately. According to the performance of Morris water maze test, the mice were divided into 5 groups randomly. The mice were fed with different drugs or distilled water for 60 d (from 4 months to 6 months). The mice were fed with the drugs from 61 d to 65 d, and 1 h later each time, the Morris water maze test was carried out. After this Morris test were finished at 65 d, the mice were killed immediately and their hippocampal tissues were isolated. Half of the hippocampal tissues were added with precooled normal saline and made into 10% (g/mL) homogenate for detecting the protein content and acetyl cholinesterase (AChE) activity. The other half was fixed with 4% paraformaldehyde and embedded with paraffin for immunohistochemical staining of amyloid β-protein (Aβ). RESULTS:Compared with model group, the results of navigation training and spatial probe training in Morris water maze test were significantly improved (P<0.05), and the activity of AChE in the hippocampal ho-mogenate was significantly decreased (P<0.05) in Q0409 treatment group. No difference in Q0409 group was observed compared with control group and positive drug (huperzine A) group. Immunohistochemical staining showed no typical "se-nile plaques" in the male mice of Q0409 group, while there was shallower and smaller brown staining in the hippocampus of the female mice of Q0409 group. The positive area of Aβ deposition decreased in the CA1 area of hippocampal tissues in Q0409 group. These results were similar to those in positive drug group. CONCLUSION:Q0409 improves the ability of learning and memory in SAM-P/8 mice, which is related to the inhibition of AChE activity and the reduction of Aβ protein deposition in the hippocampus. The effects is similar to those of huperzine A.

Detection and clinical significance of myeloid-derived suppressor cells in peripheral blood of patients with Parkinson disease / 中国病理生理杂志

AIM:To detect the myeloid-derived suppressor cells(MDSCs )in peripheral blood from the pa-tients with Parkinson disease(PD)and its clinical significance.METHODS:The patients(n=80)diagnosed PD from January 2016 to March 2017 in our hospital and 20 healthy volunteers were selected as the subjects.According to the Hoehn-Yahr staging,80 PD patients were staged,of whom 22 were Ⅰ,24 were Ⅱ,20 were Ⅲ,14 were Ⅳ,and 0 was Ⅴ. Peripheral blood(5 mL)samples from the patients with PD and the healthy volunteers were collected and the mononuclear cells were isolated.The levels of CD14 +CD11b+cells and CD14 -CD11b+cells in the peripheral blood were detected by flow cytometry.The two populations of the cells were sorted by magnetic beads.The mRNA levels of arginase 1(ARG1),interleukin-10(IL-10)and cyclooxygenase 2(COX-2)were detected by qPCR.The expression of surface membrane pro-teins CD14 and CD11b,and immunosuppressive factors ARG1,IL-10 and COX-2 was determined by Western blot and ELISA.RESULTS:No significant change of CD14 +CD11b+cells between the patients with PD and normal controls was observed,but the cells with CD14 -CD11b+increased significantly in the patients with PD compared with the control peo-ple(P<0.05).The CD14 -CD11b+cells in peripheral blood of the patients were related to the stage of Hoehn-Yahr.The CD14-CD11b+and CD14+CD11b+cells showed high levels of IL-10 and COX-2,and the high level of ARG1 was only expressed in the CD14 -CD11b+cells.The expression of ARG1 in the CD14 -CD11b+population from PD patients was significantly different from that of CD14+CD11b+population and normal subjects(P<0.05).CONCLUSION:The CD14-CD11b+cells and ARG1 expression level in peripheral blood of the PD patients can be used to evaluate the patho -genesis and staging.Immunosuppression may play an important role in the pathogenesis and development of PD.

Understanding Qi Running in the Meridians as Interstitial Fluid Flowing via Interstitial Space of Low Hydraulic Resistance / 中国结合医学杂志

Qi, blood and the meridians are fundamental concepts in Chinese medicine (CM), which are components of the human body and maintain physiological function. Pathological changes of qi, blood and meridians may lead to discomfort and disease. Treatment with acupuncture or herbal medicine aims to regulate qi and blood so as to recover normal function of the meridians. This paper explores the nature of qi as well as compares and correlates them with the structures of the human body. We propose a conceptualization of qi as being similar to the interstitial fluid, and the meridians as being similar to interstitial space of low hydraulic resistance in the body. Hence, qi running in the meridians can be understood as interstitial fluid flowing via interstitial space of low hydraulic resistance.

Molecular mechanism of Xuebijing injection in treatment of sepsis according to “drug-target-pathway” network / 药学学报

This study was aimed to construct a “drug-target-pathway” network of Xuebijing injection for sepsis treatment in an effort to explore the “multi-components, multi-targets, multi-pathways” mechanism based on “system-system” research mode. Active ingredients of Xuebijing injection were used to predict the potential targets according to reversed pharmacophore matching method. The pathway information was acquired from DAVID and KEGG database. The Cytoscape software was used to construct the “ingredient-target-pathway” network of Xuebijing injection for sepsis treatment. The results showed that 21 major active ingredients of Xuebijing injection regulated 550 targets (HRAS, GSK3B, BTK, AK, et al) and affected 10 inflammation and immune-related pathways, such as B cell receptor signaling pathway, VEGF signaling pathway, natural killer cell mediated cytotoxicity, Toll-like receptor signaling pathway. The sepsis therapeutic effect of Xuebijing injection reflected the action features of traditional Chinese medicine as multi-ingredients, multi-targets, multi-pathways. This research clarifies the material basis of Xuebijing injection for anti-inflammation and immunoregulation, providing a scientific basis for elucidation the mechanism of Xuebijing injection in the treatment of sepsis.

Strategy of constructing post-market integral evaluation system of traditional Chinese medicine injection / 中国中药杂志

As an important representative of modern Chinese medicine, traditional Chinese medicine (TCM) injzection has become an indispensable part of the Chinese medicine industry. However, its development is now restricted by the bottleneck of insufficient core competitiveness, low-level research and production, even injection quality and the safe use are not guaranteed. Thus, it is urgent to reevaluate post-marketing TCM injection generally and to make secondary development. Under current circumstances, taking major brands which have good clinical and market foundation, as well as research value, as the main subject of cultivation and evaluation is an important approach to innovative development of TCM injection industry. Unlike oral proprietary Chinese medicine, the cultivatation of major brands of TCM injection needs higher technical support, quality standards and more timely feedback. Therefore, a post-market integral evaluation system adaptive to TCM injection is required. This article discussed some key points on the construction of a post-market integral evaluation system of TCM injection in three levels： optimizing evaluation methods, building synergistic innovation platforms which combine the medical research institutions and pharmaceutical enterprises, and finally constructing the integral evaluation system. A "five to one" structure has been proposed to enhance TCM injection effectiveness, safety and adaptability on the whole, which are from the following aspects： mechanism research, clinical evidence validation, literature information mining, sustainable development of resources and industrialization operation.
