Chinese journal of integrative medicine 2018;24(10):794-800
Diabetic peripheral neuropathy (DPN) seriously affects the quality of life in patients with type 2 diabetes mellitus. This paper reviews the role of Chinese medicine in the main treatment goal of DPN, including protecting pancreatic β-cells, in the use of antioxidation therapy to delay disease progression, and in the endpoint of neural repair and regeneration. We propose that protecting the body from injury caused by high glucose and oxidative stress, and promoting repair and regeneration of nerves should be the research direction for the prevention and treatment of DPN.
2.Coptidis Rhizoma-Contained Traditional Formulae for Insomnia: A Potential to Prevent Diabetes?
Chinese journal of integrative medicine 2018;24(10):785-788
It has been well known that insomnia and sleep deprivation can lead to many metabolic diseases such as type 2 diabete mellitus (T2DM). Chinese medicine (CM) has been used to improve insomnia and showed many good therapeutic effects. Some Coptidis Rhizoma-contained traditional formulae have been found to exert obvious effects on insomnia, such as Jiaotai Pill (), Huanglian Ejiao Decoction (), Huanglian Wendan Decoction (), Niuhuang Qingxin Pill (), and Zhusha Anshen Pill (). Coptidis Rhizoma, a traditional herbal medicine which can purge Xin (Heart) fire, is the most important component of these formulas. Studies have found that these formulae could improve T2DM symptoms. We hypothesized that treating insomnia theoretically may help to prevent diabetes and organized many experimental studies in this review and concluded that Coptidis Rhizoma-contained traditional formulae for insomnia might be a potential to prevent diabetes.

BACKGROUNDThe domestic prevalence of chronic hepatitis B (CHB) in China is 7.18% in 2006, imposing great societal healthcare burdens. Nucleot(s)ide analogues (NUCs) anti-hepatitis B virus (HBV) therapies are widely applied despite the relatively low rate of seroconversion and high risk of drug-resistant mutation. More effective treatments for CHB deserve further explorations. Combined therapy of NUCs plus Chinese herbal medicine (CHM) is widely accepted in China, which is recognized as a prospective alternative approach. The study was primarily designed to confirm the hypothesis that Tiaogan-Yipi Granule (, TGYP) or Tiaogan-Jianpi-Jiedu Granule (, TGJPJD) plus entecavir tablet (ETV) was superior over ETV monotherapy in enhancing HBeAg loss rate.
METHODSThe study was a nationwide, large-scale, multi-center, double-blind, randomized, placebo-controlled trial with a designed duration of 108 weeks. A total of 16 hospitals and 596 eligible Chinese HBeAg positive CHB patients were enrolled from November 2012 to September 2013 and randomly allocated into 2 groups in 1:1 ratio via central randomization system: experimental group (EG) and control group (CG). Subjects in EG received CM formulae (TGYP or TGJPJD, 50 g per dose, twice daily) plus ETV tablet (or ETV placebo) 0.5 mg per day in the first 24 weeks (stage 1), and CHM granule plus ETV tablet (0.5 mg per day) from week 25 to 108 (stage 2). Subjects in CG received CHM Granule placebo plus ETV tablet (0.5 mg per day) for 108 weeks throughout the trial. The assessments of primary outcomes (HBV serum markers and HBV-DNA) were conducted by a third-party College of American Pathologists (CAP) qualified laboratory. Adverse effects were observed in the hospitals of recruitment.
DISCUSSIONThe study was designed to compare the curative effect of CM plus ETV and ETV monotherapy in respect of HBeAg loss, which is recognized by the European Association for the Study of the Liver as "a valuable endpoint". We believe this trial could provide a reliable status for patients' "journey" towards durable responses after treatment discontinuation. The trial was registered before recruitment on Chinese Clinical trial registry (No. ChiCTR-TRC-12002784, Version 1.0, 2015/12/23).

OBJECTIVETo investigate the effects of the flower buds extract of Tussilago farfara Linné (Farfarae Flos; FF) on focal cerebral ischemia through regulation of inflammatory responses in activated microglia.
METHODSBrain ischemia was induced in Sprague-Dawley rats by a transient middle cerebral artery occlusion (tMCAO) for 90 min and reperfusion for 24 h. Twenty rats were randomly divided into 4 groups (n=5 per group): normal, tMCAO-induced ischemic control, tMCAO plus FF extract 300 mg/kg-treated, and tMCAO plus MK-801 1 mg/kg-treated as reference drug. FF extract (300 mg/kg, p.o.) or MK-801 (1 mg/kg, i.p.) was administered after reperfusion. Brain infarction was measured by 2,3,5,-triphenyltetrazolium chloride staining. Neuronal damage was observed by haematoxylin eosin, Nissl staining and immunohistochemistry using anti-neuronal nuclei (NeuN), anti-glial fibrillary acidic protein (GFAP), and anti-CD11b/c (OX42) antibodies in ischemic brain. The expressions of inducible nitric oxide synthase (iNOS), tumor necrosis factor (TNF-α), and hypoxia-inducible factor-1a (HIF-1α) were determined by Western blot. BV2 microglial cells were treated with FF extract or its main bioactive compound, tussilagone with or without lipopolysaccharide (LPS). Nitric oxide (NO) production was measured in culture medium by Griess assay. The expressions of iNOS, COX-2 and pro-inflammatory cytokines mRNA were analyzed by reverse transcription-polymerase chain reaction. The expression of iNOS, and COX-2 proteins, the phosphorylation of ERK1/2, JNK, and p38 MAPK and the nuclear expression of NF-κB p65 in BV2 cells were determined by Western blot.
RESULTSFF extract significantly decreased brain infarctions in ischemic rats (P<0.01). The neuronal death and the microglia/astrocytes activation in ischemic brains were inhibited by FF extract. FF extract also suppressed iNOS, TNF-α, and HIF-1α expression in ischemic brains. FF extract (0.2 and 0.5 mg/mL, P<0.01) and tussilagone 20 and 50 μmol/L, P<0.01) significantly decreased LPS-induced NO production in BV2 microglia through downregulation of iNOS mRNA and protein expression. FF extract and tussilagone significantly inhibited LPS-induced expression of TNF-α, IL-1β, and IL-6 mRNA, and also suppressed the phosphorylation of ERK1/2, JNK and p38 MAPK and the nuclear expression of NF-κB in a dose-dependent manner.
CONCLUSIONSFF extract has a neuroprotective effect in ischemic stroke by the decrease of brain infarction, and the inhibition of neuronal death and microglial activation-mediated inflammatory responses.

OBJECTIVETo investigate the neuro-protective effects of Acanthopanax senticosus Harms (EAS) on mesencephalic mitochondria and the mechanism of action, using a mouse model of Parkinson's disease (PD).
METHODSThe chemical fingerprint analysis of the extract of Acanthopanax senticosus Harms (EAS) was performed using the ultra performance liquid chromatograph and time of flight mass spectrometry. Thirty mice were randomly divided into the control group, the MPTP model group, and the EAS treated group with MPTP (MPTP+EAS group, 10 in each group). The MPTP model group and the MPTP+EAS group received MPTP-HCl (30 mg/kg i.p) once a day for 5 days. The control group received an equal volume of saline (20 mL/kg i.p) once a day for 5 days. Induced by 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine hydrochloride daily (MPTP-HCl, 30 mg/kg) for 5 days, the PD mice were treated with EAS at 45.5 mg/kg daily for 20 days. The behavioral testing of mice was carried out using the pole-climbing test. The integrity and functions of neurons were examined in mesencephalic mitochondria in a PD mouse model, including nicotinamide adenine dinucleotide dehydrogenase ubiquinone flavoprotein 2 (NDUFV2), mitochondrially encoded nicotinamide adenine dinucleotide dehydrogenase 1 (MT-ND1), succinate dehydrogenase complex subunit A (SDHA), and succinate dehydrogenase cytochrome b560 subunit (SDHC).
RESULTSAfter treatment with EAS, the behavioral changes induced by MPTP were attenuated significantly (P<0.05). EAS protected the mesencephalic mitochondria from swelling and attenuated the decreases in their membrane potential (both P<0.05), which was supported by an ultra-structural level analysis. The changes in reactive oxygen species (ROS), malonic dialdehyde (MDA), oxidative phosphorylation (OXPHOS) system 4 subunits levels and PD-related proteins expressions (parkin, Pink1, DJ-1, α-synuclein, and Lrrk2) reverted to near normal levels (all P<0.05), based on the results of immune-histological and Western blotting observations.
CONCLUSIONSThe neuro-protective effects of EAS are linked to protecting mice against MPTP-induced mitochondrial dysfunction and structural damage. Therefore, EAS is a promising candidate for the prevention or treatment of mitochondrial neurodegenerative disorders, such as PD.

OBJECTIVETo assess the effectiveness of Yishen Jiangu Granules (, YSJGG) on aromatase inhibitor-associated musculoskeletal symptoms (AIMSS).
METHODSA single-arm, open-label study was conducted in 34 postmenopausal women with breast cancer who experienced AIMSS. Patients were treated with YSJGG for 12 weeks (12.4 g orally twice daily). The primary outcome was a change in the mean worst pain score of Brief Pain Inventory-Short Form (BPI-SF) over 12 weeks, and the second outcomes included changes in pain severity and pain-related interference of BPI-SF and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Modified Score for the Assessment of Chronic Rheumatoid Affections of the Hands (M-SACRAH), the Functional Assessment of Cancer Therapy-Breast (FACT-B), bone mineral density (BMD) and blood indices such as calcium (Ca), phosphate (P), and alkaline phosphatase (ALP).
RESULTSOf 37 women recruited, 30 initiated the therapy and 24 were evaluable at 12 weeks. The primary outcome (BPI-SF worst pain scores) achieved a 2.17-point reduction compared with baseline (5.75±1.87 vs 3.58±2.15, P<0.01). There were reductions in pain severity (decreased 1.65, P<0.01) and pain-related interference (decreased 2.55, P<0.01). The changes in WOMAC and M-SACRAH scores were similar to BPI-SF (P<0.05). In the FACT-B, only physical well-being and functional well-being were improved compared with baseline (P<0.05). No clinical differences were found in BMD, Ca, P and ALP.
CONCLUSIONYSJGG is an effective and well-tolerated agent to reduce AIMSS.

OBJECTIVETo evaluate the efficacy of Xuebijing Injection (, XBJ) on the lung injury induced by cardiopulmonary bypass (CPB).
METHODSFifty patients undergoing CPB were randomized to either the saline group or XBJ group according to a random number table (25 cases in each group). The patients in the saline group received saline and patients in XBJ group received XBJ at 12 h prior to the operation, at the beginning of the operation, and at 12 h after the second injection. The PaO/FiO at extubation 3 days post-operation, duration of ventilation in the intensive care unit (ICU), and lengths of stay in the ICU and hospital were recorded. The levels of inflammatory mediators including interleukin (IL)-1β, IL-8, IL-10, and C-reactive protein (CRP) in bronchoalveolar lavage fluid (BALF) and plasma were measured. The neutrophil count and elastase neutrophil elastase in BALF were also measured. In addition, adverse events were monitored.
RESULTSThe PaO/FiO in the XBJ group was higher than that in the saline group from 12 to 72 h post-operation (all P<0.05). The blood levels of IL-1β, IL-8, and CRP in the XBJ group from 12 to 72 h were all significantly lower than those in the saline group (all P<0.05). In contrast, the level of the anti-inflammatory cytokine IL-10 was significantly higher in the XBJ group than in the saline group (P<0.05). In addition, 4 patients presented with atelectasis in the saline group and none in the XBJ group. Ten patients experienced mild acute respiratory distress syndrome (ARDS) during hospitalization, and 5 patients with mild ARDS were in the XBJ group (P<0.05).
CONCLUSIONXBJ shows protective potential against lung injury in patients who undergo CPB surgery, possibly through the downregulation of inflammatory mediators, reduction in neutrophil infiltration, and upregulation of IL-10 (Trial registry: ChiCTR-TRC-14004628).

Type 2 diabetes mellitus (T2DM) is one of the common endocrinology diseases that greatly affects the health care sector and economy. Application of hypoglycemic drugs has its own drawbacks and the use of non-drug therapy on treating T2DM has drawn much attention recently. This paper reviewed the research development of the non-pharmacological interventions on T2DM in recent years, including dietary therapy, exercise therapy, psychotherapy, acupuncture and moxibustion therapies and so on. The authors mentioned the problems in the research of non-drug treatment for blood glucose control of T2DM and put forward new ideas for the research in the future. Further well-designed trials with large sample size and long-term follow-up are needed to confirm current conclusions.

OBJECTIVETo explore the effectiveness and safety of acupuncture in patients with post-stroke dysphagia by an update meta-analysis.
METHODSPotentially eligible RCTs aimed to evaluate the effects of acupuncture vs. non-acupuncture treatments, such as rehabilitation training or routine medication on the swallowing difficulty after stroke were searched from PubMed, Cochrane Library, China National Knowledge Infrastructure, and other database from the earliest record to June 2016. Patient demographics, regimens for acupuncture, type of controls, methods of randomization, and measurements of the clinical symptoms of dysphagia were retrieved. The relative risk (RR) and 95% confidence interval (CI) of effective rate of dysphagia was calculated after intervention performed following admission. Subgroup analyses and a metaregression analysis were performed to describe the heterogeneity.
RESULTSTwenty-nine RCTs comprising 2,190 patients were included. The included studies had a medium quality grade based on the Consolidated Standards of Reporting Trials (CONSORT) and Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA) checklist. Acupuncture therapy provided a higher effective rate compared with nonacupuncture treatments [RR=1.33, 95% confidence interval (CI), 1.25 to 1.43]. Subgroup and meta-regression analyses suggested that acupuncture intensity and measurement method were main sources of heterogeneity and resulted in a significant difference for pooled effect size. No severe adverse events were documented in these RCTs.
CONCLUSIONSOur meta-analysis provides a new evidence supporting the efficacy and safety of acupuncture in treatment to post-stroke dysphagia in short-term compared with rehabilitation or medication. More high-quality and large-scale research studies are needed.
