Sequential Therapy Based on Evolvement of Patterns: A New Model for Treatment of Alzheimer's Disease
Abstract：In order to solve the problem of long-term (>9 months) efficacy in the treatment of Alzheimer's disease (AD) by conventional therapy (CT), a staged and multiply-targeted sequential therapy based on the evolvement of patterns (STEP) was developed. Its main innovations include: (1) the time order of evolution of patterns defined by Chinese medicine (CM) in AD was found, that is, "the orderly pattern evolution starting from Shen (Kidney) deficiency, progressing to phlegm, stasis and fire, and worsening to severe toxin as well as functional collapse"; (2) the cascade hypothesis of Shen deficiency in AD and its sequential therapy based on Shen-reinforcing was proposed, that is, "reinforcing Shen in the early stage and throughout the whole process, resolving phlegm, activating blood and purging fire in the middle stage, detoxifying and replenishing vitality to stop the collapse in the advanced stage", and through meta-analysis, clinical drug use was optimized, thus the leap from "inferential selection" to "evidence-based selection" was realized; (3) the STEP regimen combined with CT maintained cognitive and behavioral stability in AD patients for at least 12 months, with cognitive enhancement and behavioral synergy after 9 months, and cognitive benefit was superior to CT at 9, 12, 15, 18, 21, and 24 months, respectively. The 2-year cognitive improvement rate was increased by 25.64% (P=0.020) and the cognitive deterioration rate was decreased by 48.71% (P=0.000). Among them, the cognitive and functional benefits of Shen-reinforcing therapy for very early AD (350 cases) for 1 year were better than the placebo (P<0.001), and the dementia conversion rate was reduced by 8.85% (P=0.002). The behavioral symptomatic relief of patients with vascular dementia received fire-purging therapy (540 cases) was superior to those received CT (P=0.016). These data suggested that the STEP regimen has synergistic effects on CTs at least in terms of cognitive benefit, and the earlier the use, the greater the benefit will have. Therefore, the STEP regimen should be considered as one of the clinical options, particularly for the dearth of effective pharmaceutical or immunological interventions that are currently available for AD.Keywords：Alzheimer's disease;pattern evolvement;sequential therapy;Chinese medicine- 398

- Abstract：Objective:To assess the effect and safety of Huannao Yicong Formula (还脑益聪方, HYF) in the treatment of patients with mild-to-moderate Alzheimer's disease (AD).Methods:Sixty patients with mild-tomoderate AD were evenly randomized into HYF group and donepezil group with the random number method. Patients in the HYF group took 5 g of HYF granules twice daily and 5 mg placebo of donepezil once daily. Patients in the donepezil group took 5 mg donepezil once daily and 5 g placebo of HYF granules twice daily. The intervention lasted for 6 months. Clinical researchers, participants and statisticians were blinded to the treatment assignment throughout the study. The primary outcomes were scores of Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) and Chinese Medicine Symptom Scale (CM-SS). The secondary outcomes were scores of Montreal Cognitive Assessment (MoCA) test and Mini-Mental State Exam (MMSE). The serum levels of acetylcholinesterase (AchE) and amyloid-β protein 42 (Aβ42) were detected with enzymelinked immunosorbent assay kits. The scale assessments were conducted at baseline, the 3rd and 6th months of treatment, respectively. Biochemistry tests were conducted at baseline and the 6th month of treatment.Results:A total of 52 patients completed the trial, 28 in HYF group and 24 in donepezil group. Compared with the baseline, HYF and donepezil significantly decreased the total scores of ADAS-Cog and CM-SS, and significantly increased the scores of MoCA and MMSE after 6-month treatment (all P<0.01). Both treatments remarkably reduced the serum levels of AchE and Aβ42 (both P<0.05). The CM-SS total effective rate of HYF was significantly higher than donepezil [75.00% (21/28) vs. 54.17% (13/24), P<0.05]. No severe adverse events were observed in both groups.Conclusion:HYF is effective and safe for improving the cognitive function in mildto-moderate AD patients.

Published：2021-08-27 - Abstract：Objective:To evaluate the effect of tai chi exercise on cardiac and static lung function for older community-dwelling adults at risk of ischemic stroke.Methods:A total of 170 older community-dwelling adults (aged 55–75 years old) at risk of ischemic stroke were allocated to either tai chi training group (85 cases, five 60-min sessions of tai chi training per week for 12 weeks) or control group (85 cases, usual pbysical activity for 12 weeks) using a computer-generated randomization. The echocardiographic parameters of cardiac structure, cardiac function and static lung function were measured at baseline, after 12 weeks of intervention and additional 12-week follow-up period by a blinded professional staff member using a color Doppler ultrasound imaging device or a cardiopulmonary function instrument. The t test and linear mixed model based on the intention-to-treat analysis principle was used to calculate the effect. The adverse effect was observed.Results:Most of echocardiographic parameters on the cardiac structure, cardiac function and static lung function between the tai chi group and control group did not have a significant difference either post 12-week intervention or additional 12-week follow-up period. Only three parameters involving in right ventricular diameter (P=0.024), main pulmonary artery diameter (P=0.002) and vital capacity maximum (P=0.036) were beneficial to be improved in the tai chi group compared to the control group by the analysis of mixed linear model. No adverse effects were found during the intervention period.Conclusions:The 12-week tai chi exercise did not have an obvious beneficial effect on cardiac structure, cardiac function and static lung function in older community-dwelling adults at risk of ischemic stroke.

Unique MicroRNAs Signature of Lymphocyte of Yang and Yin Syndromes in Acute Ischemic Stroke Patients
Abstract：Objective:To identify the differentially expressed microRNAs (miRNAs) profiles of yang and yin syndromes in patients with acute ischemic stroke, and to provide the molecular basis of the classification of these two syndrome types in acute ischemic stroke patients.Methods:A microarray assay was performed to assess the expression pattern of miRNAs in the lymphocyte of acute ischemic stroke patients. Target genes for the deregulated miRNAs were predicated using the online bioinformatic algorithms and functional annotation via Kyoto encyclopedia of genes and genomes pathway analysis for miRNAs predicted targets was carried out. Based on the predicted target genes of differentially expressed miRNAs, the miRNA-gene-network and miRNA-pathwaynetwork were constructed.Results:Yang score based on tongue texture, urine, dejecta, and appearance, etc. showed that clinical symptoms were distinct between yang and yin syndromes. There were significantly higher total leukocyte number and lower total protein level in patients with yang syndrome compared with those in patients with yin syndrome (P<0.05). Comprehensive miRNA analysis identified 36 unique down-regulated miRNAs in yang syndrome group, and 20 unique down-regulated and 2 unique up-regulated miRNAs in yin syndrome group. The key regulatory miRNAs, gene, and pathways in the yang syndrome were hsa-miR-93-5p and -320b, enabled homolog, the metabolic pathways and mitogen-activated protein kinase signaling pathways, respectively, while those in the yin syndrome were hsa-miR-424-5p and -106b-5p, CNOT4, hepatitis B and pathways in cancer, respectively.Conclusion:These results offered insight into the molecular basis underlying the different pathogenesis of yang or yin syndrome, providing clues for the individualized therapeutic strategies of acute ischemic stroke.Keywords：acute ischemic stroke;yang syndrome;yin syndrome;microRNAs profile;diagnosis;Chinese medicine- 468

Published：2021-08-27 - Abstract：Objective:To evaluate the effect of Pien Tze Huang (片仔癀, PZH) on breast cancer chemoresistance and related epithelial-mesenchymal transition (EMT) and investigate the underlying mechanisms.Methods:3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay was used to determine the cell viability. Adriamycin (ADR) staining observed by fluorescence microscope was performed to detect the accumulation of ADR. Transwell assay was used to analyze the cell migration and invasion. Western-blot was performed to detect the protein expression of related genes.Results:MCF-7/ADR cells were resistant to ADR treatment, and PZH treatment inhibited the viability of MCF-7/ADR cells in a dose-dependent manner. PZH treatment also increased the intercellular accumulation of ADR and down-regulated the expression of ABCG2 and ABCB1 in MCF-7/ADR cells (P<0.05). In addition, PZH treatment inhibited EMT, migration and invasion of MCF-7/ADR cells (P<0.05). Moreover, PZH suppressed activation of transforming growth factor β1 (TGF-β) signaling in MCF-7/ADR cells (P<0.05).Conclusion:PZH treatment can effectively overcome chemoresistance via down-regulating ABCG2, ABCB1 and inhibit EMT in ADR resistant human breast cancer cells via suppression of the TGF-β1 pathway.Keywords：Pien Tze Huang;Chinese medicine;breast cancer;chemoresistance;epithelial-mesenchymal transition

Published：2021-08-27 - Abstract：Objective:To test the hypothesis that the inhibition of endoplasmic reticulum (ER) stress-induced apoptosis in oxidized low-density lipoproteins (ox-LDL)-induced human aortic-vascular smooth muscle cells (HA-VSMCs) was associated with suppression of the protein kinase RNA-like ER kinase (PERK)-eukaryotic translation initiation factor 2α (eIF2α)-activating transcription factor 4 (ATF4)-CCAAT/enhancer binding protein homologous protein (CHOP) signaling pathway by Pollen Typhae total flavone (PTF).Methods:Primary HA-VSMCs were cultured and identified. The cultured HA-VSMCs were randomized into 5 groups, including a normal control group, an ox-LDL group (70 μg/mL high ox-LDL), an HPTF group (70 μg/mL high ox-LDL+500 μg/mL PTF), an MPTF group (70 μg/mL high ox-LDL+250 μg/mL PTF), and a LPTF group (70 μg/mL high ox-LDL+100 μg/mL PTF) in the first part; and a normal control group, an ox-LDL group (70 μg/mL high ox-LDL), an MPTF group (70 μg/mL high ox-LDL+250 μg/mL PTF), a shRNA group (transducted with PERK shRNA lentiviral particles), a scramble shRNA group (transducted with control shRNA lentiviral particles), an MPTF+ox-LDL+shRNA group (250 μg/mL PTF+70 μg/mL high ox-LDL+PERK shRNA lentiviral particles) and an ox-LDL+shRNA group (70 μg/mL high ox-LDL+PERK shRNA lentiviral particles) in the second part. The protein expression levels of ER-associated apoptosis proteins were detected by Western blot, and their mRNA expression levels were detected by quantitative real-time reverse transcription-polymerase chain reaction. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was applied to test cell viability, and the level of apoptosis was monitored by flow cytometry.Results:The MTT assay and flow cytometry showed that the ox-LDL group had a significant increase in apoptosis, which was attenuated in PTF treatment groups and shRNA groups. Moreover, the ox-LDL group had increased protein and mRNA levels of binding immunoglobulin protein and ER-associated apoptosis proteins, such as PERK, eIF2α, ATF4 and CHOP, which were attenuated in PTF treatment groups and shRNA groups.Conclusions:The apoptosis induced by ox-LDL had a strong relation to ER stress. The protective effect of PTF on ER stressinduced apoptosis was associated with inhibition of the PERK-eIF2α-ATF4-CHOP pathway, which might be a potential therapeutic strategy for enhancing the stability of atherosclerotic plaques.Keywords：Pollen Typhae total flavone;endoplasmic reticulum stress;protein kinase RNA-like endoplasmic reticulum kinase-eukaryotic translation initiation factor 2α-activating transcription factor 4-CCAAT/enhancer binding protein homologous protein pathway;apoptosis;vulnerable atherosclerotic plaque

- Abstract：Objective:To investigate the immediate analgesic effect of sinew acupuncture for patients with soft-tissue injuries (STIs).Methods:Two hundreds eligible adult patients suffering from STIs were recruited and received sinew acupuncture with flexible treatment schedules. The number of treatment sessions was pragmatically decided by each patient on the basis of their pain relief. The outcome measurement was the change of pain rating in the Visual Analogue Scale (VAS) during the first 5 sessions. The adverse effect was also observed.Results:Of the 200 patients recruited, 7 were excluded due to incomplete data. In total, 888 sinew acupuncture treatments were administered to patients at 14 injury sites (including head, neck, shoulder, arm, chest, elbow, wrist, hand, waist and hip, knee, thigh, calf, ankle, and foot) where pain was felt. Compared with the baseline, the VAS rating after the first and last treatments were both significantly reduced at all the injury sites (P<0.01). The VAS rating was also significantly reduced after each session of treatment in the first five sessions (P<0.01). No serious adverse effect was observed.Conclusion:Sinew acupuncture had not only an immediate analgesic effect for STIs, but also an accumulated analgesic effect during the first 5 treatment sessions.Keywords：sinew acupuncture;soft-tissue injury;analgesic effect;pain;Visual Analogue Scale

Published：2021-08-27 - Abstract：Objective:To evaluate the involvement of different CD4+ T cell subtypes in the anti-asthmatic effects of acupuncture in asthmatic mice.Methods:BALB/c mice were challenged by ovalbumin (OVA) for the establishment of experimental asthma model. Mice were divided into 4 groups by a random number table including the normal control, asthma model, acupuncture and sham acupuncture groups (14 per group). Acupoints Dazhui (GV 14), bilateral Fengmen (BL 12) and Feishu (BL 13) were selected for manual acupuncture treatment every other day for 4 weeks and Huantiao (GB 30) was selected for sham acupuncture. Airway hyperresponsiveness was examined by Buxco Pulmonary System. Pulmonary histopathology analysis was performed for inflammatory cell infiltration and mucus hypersecretion by haematoxylin eosin staining and periodic acid-Schiff staining. Inflammatory mediators assays of serum were investigated by enzyme-linked immunosorbent assay and Bio-Plex. CD4+ T cell subpopulations including the expression levels of important factors in T lymphocyte polarization in lung tissue were examined by flow cytometric and Western blot analyses. Related pathways were detected by Western blot assay.Results:Compared with the OVA-induced asthma model group, acupuncture could attenuate airway hyperresponsiveness, inhibit inflammatory cell infiltration and mucus hypersecretion (P<0.05 or P<0.01). Furthermore, acupuncture increased the expressions of T-bet and Foxp3+, the cell numbers of CD4+ interferon gamma (IFN-γ)+ and CD4+ Foxp3+ in lung tissue and the level of Treg type cytokine interleukin (IL)-10 in serum (P<0.05 or P<0.01). Meanwhile, acupuncture reduced the RAR-related orphan receptor gamma t (RORγt) level, the cell numbers of CD4+ IL-17A+ as well as the levels of IL-5, IL-13 and IL-17A in serum (P<0.05 or P<0.01). In addition, both acupuncture and sham acupuncture could inhibit the phosphorylation of p38 and p44/42 (P<0.01).Conclusion:Acupuncture could alleviate allergic airway inflammation by strengthening the activities of Th1 and Treg, thus regulating the balance of CD4+ T cell subtypes in experimental asthmatic mice.Keywords：acupuncture;asthma;Th2;Th17;Treg

- Abstract：Objective:To evaluate the effect of Zhizhu Kuanzhong Capsules (枳术宽中胶囊, ZKC) for functional dyspepsia (FD) through meta-analysis.Methods:Online databases, including PubMed, EM base, China National Knowledge Infrastructure, Wanfang Data, VIP database and Cochrane Library, were searched for randomized controlled trials (RCTs) of ZKC for FD from the inception to April, 2016. Trials were selected according to inclusion criteria and were evaluated with quality assessment standards in the Cochrane Handbook for Systematic Reviews of Interventions and Jadad scale. RevMan 5.3 and GRADEprofiler 3.6 were used for statistical analysis and evidence quality assessment.Results:Twenty-three trials with 2,496 patients were included and most of them were of poor methodological quality. ZKC alone or ZKC combined with routine Western medicine (WM) showed a better clinical effect rate compared with the control group of WM [odds ratio (OR)=3.32, 95% confidence interval (2.66, 4.15), P<0.00001]. No serious adverse reactions were reported.Conclusions:ZKC alone or ZKC combined with routine WM could significantly improve the clinical effective rate in the treatment of FD. The quality of the evidence is low, so it is necessary to design multicenter, strictly randomized and double-blind controlled trials with large samples to validate the conclusions.Keywords：Zhizhu Kuanzhong Capsules;functional dyspepsia;randomized controlled trial;meta-analysis;Chinese medicine

- Abstract：As the worldwide population ages, the prevalence of Alzheimer's disease (AD) increases. However, the results of promising medications have been unsatisfactory. Chinese acupuncture has a long history of treating dementia, but lack of evidence from well-designed randomized controlled trials that validate its efficacy and safety, as well as its lack of clear underlying mechanisms, contribute to its limited application in clinical practice. In recent years, brain imaging technologies, such as functional magnetic resonance imaging and positron emission tomography, have been used to assess brain responses to acupuncture in a dynamic, visual, and objective way. These techniques are frequently used to explore neurological mechanisms of responses to acupuncture in AD and provide neuroimaging evidence as well as starting points to elucidate the possible mechanisms. This review summarizes the existing brain imaging evidence that explains the effects of acupuncture for AD and analyzes brain responses to acupuncture at cognitive-related acupoints [Baihui (GV 20), Shenmen (HT 7), Zusanli (ST 36), Neiguan (PC 6), and Taixi (KI 3)] from perspectives of acupoint specificity and acupoint combinations. Key issues and directions to consider in future studies are also put forward. This review should deepen our understanding of how brain imaging studies can be used to explore the underlying mechanisms of acupuncture in AD.Keywords：acupuncture;Alzheimer's disease;brain response;acupoint specificity;neuroimaging
