Functional characterization of nine critical genes encoding rate-limiting enzymes in the flavonoid biosynthesis of the medicinal herb Grona styracifolia.

Grona styracifolia is a photophilous legume that contains abundant flavonoids with multiple pharmacological activities, which is used to cure urethral and biliary calculus in China for thousands of years. The authentication of the rate-limiting enzymes involved in the flavonoids biosynthesis pathway enabled a better understanding of the molecular aspect of quality formation and modulation of this medicinal herb. In this study, the chemical distribution characteristics and content of flavonoids in different tissues of Grona styracifolia were analyzed using ultraperormance liquid chromatography coupled with Q-TOF mass spectrometry and showed that active flavonoids were primarily synthesized and stored in the leaves. Subsequently, RNA sequencing (RNA-seq)-based transcriptome profiling of the different tissues revealed that the flavonoids biosynthesis in the leaves was the most active. Meanwhile, 27 full-length transcripts inferred encoding vital enzymes involved in the flavonoids biosynthesis were preliminarily excavated. Finally, four CHSs, four CHIs, and one FNSII were successfully characterized by heterologous expression, which involved in three rate-limiting steps of the flavonoid biosynthetic pathway. In conclusion, these results laid a foundation for further investigation of the molecular mechanism of the biosynthesis and modulation of active flavonoids in Grona styracifolia.

Functional characterization of four mono-terpene synthases (TPSs) provided insight into the biosynthesis of volatile monoterpenes in the medicinal herb Blumea balsamifera.

Blumea balsamifera, a wooden plant belonging to the family Asteraceae, is a medicinal herb with anticancer, antiviral, and multiple pharmacological effects, which are believed to be caused by its essential oil. The essential oil from B. balsamifera is comprised of mono- and sesqui-terpenes as the majority. Unfortunately, this plant has been facing the challenge of resource shortage, which could be effectively alleviated by biological engineering. Therefore, the identification of key elements involved in the biosynthesis of active ingredients becomes an indispensable prerequisite. In this study, candidate genes encoding monoterpene synthase were screened by transcriptome sequencing combined with metabolomics profiling in the roots, stems, and leaves of B. balsamifera. Then, these candidates were successfully cloned and verified by heterologous expression and in vitro enzyme activity assays. As a result, six candidate BbTPS genes were isolated from B. balsamifera, of which three encoded single-product monoterpene synthases and one encoded a multi-product monoterpene synthase. Among them, BbTPS1, BbTPS3, and BbTPS4 could catalyze the formation of D-limonene, α-phellandrene, and L-borneol, respectively. Meanwhile, BbTPS5 functioned in catalyzing GPP into terpinol, ß-phellandrene, ß-myrcene, D-limonene, and 2-carene in vitro. In general, our results provided important elements for the synthetic biology of volatile terpenes in B. balsamifera, which laid a foundation for subsequent heterologous production of these terpenoids through metabolic engineering and increasing their yield, as well as promoting sustainable development and utilization of B. balsamifera.

Serum from acupuncture-treated asthmatic rats regulates p38-MAPK activation in airway smooth muscle cells.

OBJECTIVES: This study aimed to investigate the regulation function of acupuncture on airway smooth muscle cells (ASMCs) of asthmatic rats. METHODS: Male Sprague-Dawley rats were challenged using inhalational Ovalbumin (OVA) to establish an asthma model. The acupuncture points (GV14 for Dazhui, bilateral BL12 for Fengmen, and bilateral BL13 for Feishu) were stimulated for asthma relief. The ASMCs isolated from asthmatic rats were incubated in medium containing the serum obtained from asthmatic rats treated with acupuncture. The expression levels of p38 MAPK and p-p38 MAPK were determined by immunocytochemical and western blot. RESULTS: ASMCs were successfully isolated and cultured. The 20% acupuncture treatment of asthmatic rat serum had the least effect on the proliferation ability of asthmatic ASMCs. The serum from asthmatic rats treated with acupuncture could decrease the expression of p-p38 MAPK in asthmatic rat ASMCs. CONCLUSIONS: The serum from acupuncture-treated asthmatic rats has an effect on treating asthma in rats, and the mechanism of action may be by regulating the p38 pathway.

Metabolomic profiling for the preventive effects of dietary grape pomace against colorectal cancer.

Colorectal cancer (CRC) is one of the most common and deadly cancers worldwide. Grape pomace (GP) is a rich source of bioactive compounds with anti-inflammatory, and anticancer effects. We recently found that dietary GP had protective effects against CRC development in the azoxymethane (AOM)/dextran sulfate sodium (DSS) CRC mouse model through suppression of cell proliferation and modulation of DNA methylation. However, the underlying molecular mechanisms associated with changes in metabolites remain unexamined. This study profiled fecal metabolomic changes in a mouse CRC model in response to GP supplementation using gas chromatography-mass spectrometry (GC-MS) based metabolomic analysis. A total of 29 compounds showed significant changes due to GP supplementation, including bile acids, amino acids, fatty acids, phenols/flavonoids, glycerolipids, carbohydrates, organic acids, and others. The major changes in metabolites of feces include increased deoxycholic acid (DCA) and decreased amino acid content. Dietary GP upregulated the expression of farnesoid X receptor (FXR) downstream genes while decreasing fecal urease activity. DNA repair enzyme MutS Homolog 2 (MSH2) was upregulated by GP supplementation. Consistently, γ-H2AX, as a DNA damage marker, decreased in GP supplemented mice. Moreover, MDM2, a protein in the ataxia telangiectasia mutated (ATM) signaling, was decreased by GP supplementation. These data provided valuable metabolic clues for unraveling the protective effects of GP supplementation against CRC development.

A review of the aromatic genus Adenosma: Geographical distribution, traditional uses, phytochemistry and biological activities.

ETHNOPHARMACOLOGICAL RELEVANCE: The strongly scented genus Adenosma R. Brown (Plantaginaceae) comprises between 26 and 29 species with mainly southeast Asian distributions. Several species are used traditionally, mostly in Asian countries, for medicinal purposes including the treatment of colds and tumors, as well as stomach, liver, and skin disorders. Some species are also used as insecticides and/or insect repellents against mosquitoes or fleas. AIM OF THE REVIEW: Although the potential health benefits of Adenosma spp. are not yet well-known or well-studied in modern medicine, the aim of the present review is to provide a critical appraisal of the current state of knowledge regarding the geographical distribution, traditional uses, phytochemistry, phytochemicals and biological properties of Adenosma spp. MATERIALS AND METHODS: Electronic databases (Web of Science, Science Direct, Google Scholar, Scifinder, Microsoft Academic, eFloras), Biodiversity Heritage Library (BHL), and the China National Knowledge Infrastructure (CNKI), were searched using the key words "Adenosma", "", "", "", "nhân tran", as well as the scientific names of the species, and a library search was also conducted for articles and books related to the subject published in English, Chinese or Vietnamese, as well as Ph.D. theses and M.Sc. dissertations published before April 2020. RESULTS: Adenosma spp. is traditionally used to treat gastrointestinal disorders, hepatitis, colds, and skin problems. Phenolic acids, flavonoids, and terpenoids constitute the main phytochemicals in these plants. Several evaluations based on bioassays have demonstrated biological activity for Adenosma spp., including antidiabetic, anticancer, and insecticidal activities; extracts and isolated compounds have also shown effective biological activity. However, current research has focused only on a few species, and on limited geographical regions, mainly in China and Vietnam. More and broader ethnopharmacological studies are therefore needed to provide further evidence of the health benefits of these plants. CONCLUSIONS: Adenosma spp. are plants rich in essential oils, particularly terpenoids, and the crude extracts have valuable bioactive properties. Certain lines of research based on cell lines and animal models show the potential value in different areas of health management. Further investigation into the traditional knowledge in southeast Asian and Pacific island regions, as well as the into the toxicity and identity of the bioactive compounds and their mechanisms of action is necessary.

Dietary Alpha-Ketoglutarate Promotes Epithelial Metabolic Transition and Protects against DSS-Induced Colitis.

SCOPE: As a natural compound in foods, alpha-ketoglutarate (aKG) is one of the key metabolites maintaining energy homeostasis. This study examines the beneficial effects of dietary aKG against the development of experimental colitis and further explores the underlying molecular mechanisms. METHODS AND RESULTS: Eight-week-old male C57BL/6 mice receive drinking water with or without 1% aKG for 4 weeks. At week 3, colitis is induced by 2.5% dextran sulfate sodium (DSS) for 7 days followed by 7 days recovery. Dietary aKG supplementation decreases DSS-induced body weight loss, gross bleeding, fecal consistency score, and disease activity index. In agreement, aKG supplementation restores DSS-associated colon shortening, ameliorated mucosal damage, and macrophage infiltration into colonic tissue, which are associated with suppressed gut inflammation and Wnt signaling, and improved epithelial structure. Consistently, aKG supplementation enhances M1 to M2 macrophage polarization and strengthens intestinal barrier function. Additionally, aKG supplementation elevates colonic aKG levels while decreasing 2-hydroxyglutarate levels, which increases oxidative instead of glycolytic metabolism. CONCLUSION: aKG supplementation protects against epithelial damage and ameliorates DSS-induced colitis, which are associated with suppressed inflammation, Wnt signaling pathway, and glycolysis. Intake of foods enriched with aKG or aKG supplementation can be an alternative approach for the prevention or treatment of colitis that are common in Western societies.

Virtual screening FDA approved drugs against multiple targets of SARS-CoV-2.

The outbreak of the novel coronavirus severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19) respiratory disease, led to a global pandemic with high morbidity and mortality. Despite frenzied efforts in therapeutic development, there are currently no effective drugs for treatment, nor are there vaccines for its prevention. Drug repurposing, representing as an effective drug discovery strategy from existing drugs, is one of the most practical treatment options against the outbreak. In this study, we present a novel strategy for in silico molecular modeling screening for potential drugs that may interact with multiple main proteins of SARS-CoV-2. Targeting multiple viral proteins is a novel drug discovery concept in that it enables the potential drugs to act on different stages of the virus' life cycle, thereby potentially maximizing the drug potency. We screened 2631 US Food and Drug Administration (FDA)-approved small molecules against 4 key proteins of SARS-CoV-2 that are known as attractive targets for antiviral drug development. In total, we identified 29 drugs that could actively interact with 2 or more target proteins, with 5 drugs (avapritinib, bictegravir, ziprasidone, capmatinib, and pexidartinib) being common candidates for all 4 key host proteins and 3 of them possessing the desirable molecular properties. By overlaying docked positions of drug candidates onto individual host proteins, it has been further confirmed that the binding site conformations are conserved. The drugs identified in our screening provide potential guidance for experimental confirmation, such as in vitro molecular assays and in vivo animal testing, as well as incorporation into ongoing clinical studies.

The effect of tillage systems on phosphorus distribution and forms in rhizosphere and non-rhizosphere soil under maize (Zea mays L.) in Northeast China.

An appropriate tillage method must be implemented by maize growers to improve phosphorus dynamics in the soil in order to increase phosphorus uptake by plant. The objective of this study was to investigate the effects of tillage systems on phosphorus and its fractions in rhizosphere and non-rhizosphere soils under maize. An experimental field was established, with phosphate fertilizers applied to four treatment plots: continuous rotary tillage (CR), continuous no-tillage (CN), plowing-rotary tillage (PR), and plowing-no tillage (PN). Under the different tillage methods, the available P was increased in the non-rhizosphere region. However, the concentration of available P was reduced in the rhizosphere soil region. The soil available P decreased with the age of the crop until the maize reached physiological maturity. The non-rhizosphere region had 132.9%, 82.5%, 259.8%, and 148.4% more available P than the rhizosphere region under the CR, PR, CN, and PN treatments, respectively. The continuous no-tillage method (CN) improved the uptake of soil phosphate by maize. The concentrations of Ca2-P, Ca8-P, Fe-P, Al-P and O-P at the maturity stage were significantly lower than other seedling stages. However, there was no significant relationship between total P and the P fractions. Therefore, a continuous no-tillage method (CN) can be used by farmers to improve phosphorus availability for spring maize. Soil management practices minimizing soil disturbance can be used to impove phosphorus availability for maize roots, increase alkaline phosphatase activity in the rhizosphere soil and increase the abundance of different phosphorus fractions.

[Discussion on clinical application of "touching-bone" acupuncture technique].

The value of the "touching-bone" acupuncture technique in clinical application was explained through the investigation on the origin of the theory of the "touching-bone" acupuncture technique, the analysis on the characteristics of acupoint selection, the introduction of clinical characteristics and the discussion on the mechanism of acupuncture in treatment. The "touching-bone" acupuncture technique refers to deep needling method, originated from the short needling and shu needling of the ancient needling methodslisted in the Internal Classic. The target points are the reaction sites on meridian near to bone and the attachments of soft tissues on bone. During the needle insertion, the needle tip is thrust deeply to the bone or the needle body is closely attached to the bone so as to stimulate periosteum specifically. This needling technique contributes to the satisfactory effect on spasmodic, deep-located and intractable pain disorder, motor system diseases, mental diseases and cerebral diseases, etc. Hence, this acupuncture technique deserves to be promoted in clinical application and explored in research.

Enzyme-free fluorescent detection of microcystin-LR using hairpin DNA-templated copper nanoclusters as signal indicator.

Microcystin-LR (MC-LR) is a potent hepatotoxin that is often associated with blooms of cyanobacteria. The analysis of trace MC-LR plays important role in environmental and health fields. Herein, we developed a low-cost and enzyme-free detection method of MC-LR by using hairpin DNA-templated copper nanoclusters (hpDNA-CuNCs) as fluorescent probe. The hpDNA-template was designed and fabricated by a MC-LR aptamer loop and a double strand stem, which can specifically recognize target MC-LR with strong affinity. The AT-rich and complementary double strand stem serves as a template for the formation of CuNCs. The formed fluorescent sensing probe of hpDNA-CuNCs exhibits maximum emission wavelength at 575 nm. Upon the addition of target MC-LR into the hpDNA-CuNCs, we observed fluorescence was quenched considerably due to the high affinity between MC-LR and hpDNA aptamer strand loop, which indicated a conformational change of hairpin probe from the stem-loop DNA structure to single-stranded DNA. Then, the change of fluorescence intensity can be used to monitor the concentration of MC-LR from 0.005 to 1200 µg L-1 with a detection limit of 0.003 ng L-1. Compared with the previous reports, this method does not require complex DNA sequence design, fluorescence dye label and sophisticated experimental techniques. Moreover, the target MC-LR in real water samples has been detected.

Heavy metal pollution and potential health risks of commercially available Chinese herbal medicines.

A survey was conducted to investigate the pollution and health risks of copper (Cu), cadmium (Cd), lead (Pb), arsenic (As), mercury (Hg) and zinc (Zn) in 60 Chinese herbal medicines (CHMs) collected from a market in Kunming City, Yunnan Province, China. Furthermore, eight CHMs (Cyathulae radix, Drynariae rhizoma, Peucedani radix, Homalomenae rhizoma, Dryopteris setosa, Polygonati rhizoma, Lilii bulbus, and Linderae radix) containing high Cd concentrations were selected to further analyse their Cd chemical forms. Additionally, the dissolution rates of six heavy metals in decoction liquid were also analysed for four CHMs (Typhonii rhizoma, Linderae radix, Homalomenae rhizoma, and Cyathulae radix), and the health risks of heavy metals in CHMs were evaluated. The results showed that the Cd, Hg and Cu concentrations in the 60 CHMs exceeded the limiting values of the "Green Trade Standards of Importing & Exporting Medicinal Plants & Preparations" (WM2-2001), with exceedance ratios of 38.8%, 8.3% and 1.7%, respectively. The majority of Cd was integrated with pectates and protein in CHMs, and the other five Cd chemical forms followed the order of water-soluble > insoluble heavy metal phosphates > oxalate > residual > inorganic form, indicating that Cd had relatively low bioactivity and toxicity. The average dissolution rates of Zn, Cu, Cd, Hg, As and Pb in the four CHMs were 47.4%, 33.8%, 20.5%, 6.1%, 5.4% and 4.8%, respectively. The calculation results of hazard quotients (HQs) for Cd and Hg showed that the CHMs did not pose a threat to human health.

[Open, multicenter, phase â £ clinical trial of Shenbei Guchang capsules in treatment of diarrhea type irritable bowel syndrome].

To evaluate the safety and effectiveness of Shenbei Guchang capsules in treatment of diarrhea type irritable bowel syndrome (yang deficiency of spleen and kidney) under widely used conditions, an open, multicenter, controlled, phase Ⅳ clinical trial was conducted in the drug clinical trial centers of 16 domestic hospitals. 2 123 patients from June 10, 2011 to November 29, 2012 were enrolled in the trial. Drug clinical trial was approved by Sichuan Academy of Medical Sciences, Sichuan Provincial People's Hospital Ethics Committee before implementation. Before the start of trial, subjects were selected according to the research scheme and inclusion criteria, then they would step into the 14 d study after signing Informed Consent Form. All subjects were treated according to the research scheme, evaluated the conditions and filled in CFR sheet, to provide the evaluation data and information on safety and efficacy of Shenbei Guchang capsules. Shenbei Guchang capsules were used to treat diarrhea type irritable bowel syndrome in widely used conditions (2 123 cases), and 2 029 cases of them entered FAS set, cure+markedly effective in 1 921 cases, with a comprehensive curative effect rate of 94.68%; 2 010 cases of them entered PPS set, cure+markedly effective in 1 906 cases, with a comprehensive curative effect rate of 94.83%. The primary symptoms of IBS were abdominal pain and diarrhea. After treatment, both abdominal pain and diarrhea were improved, with significant differences (P<0.000 1). There were significant differences in traditional Chinese medicine symptom scores on both post-treatment day 7 and day 14 as compared with the conditions before treatment (P<0.000 1). 35 cases of adverse events occurred during the trial with an incidence of 1.65%, including 12 cases of drug-related adverse events (adverse reaction) with an incidence of 0.57%, mainly manifested as nausea, abdominal distension and dry mouth, most of which would be spontaneously relieved without any measures. No serious adverse events occurred. The commercially available Shenbei Guchang capsules are proved safe and effective for the treatment of diarrhea type irritable bowel syndrome (yang deficiency of spleen and kidney) under widely used conditions (2 123 cases), and can be continued for clinical promotion and application.

[Design and development of new sham-acupuncture device].

The simple and effective controlled needle devices were provided for acupuncture clinical trial so that the double blind acupuncture trial could be conducted possibly. The basic structure of filiform needle was modified. The needle handle was designed as hollow, the upper 1/3 of needle body as hollow and the lower 2/3 part as solid. The upper and lower parts were linked with an elastic unit. At the same time, the needle pad was attached. With this method, the new sham-acupuncture device was designed and developed. The new sham-acupuncture device could simulate needle insertion, manipulation and the techniques of reinforcing and reducing, without inserting into the human body. This innovation lays the foundation for perfecting the clinical randomized controlled blind trial of acupuncture.

Icetexane diterpenoids from Perovskia atriplicifolia.

Five new icetexane diterpenoids, namely, perovskatones B-D (1, 3, 4), 1α-hydroxybrussonol (2), and 1α-hydroxypisiferanol (5), were isolated from Perovskia atriplicifolia, together with a new natural product (6) and two known compounds, przewalskin E (7) and brussonol (8). The structures of the new compounds were elucidated by detailed analyses of their MS, IR, 1D, and 2D NMR data. Compounds 1-8 were assayed for their inhibitory hepatitis B virus activities in the HepG 2.2.15 cell line. The results suggested that compounds 1 and 2 possessed noticeable anti-hepatitis B virus activity in vitro, suppressing the replication of hepatitis B virus DNA with selectivity index values of 154.3 and 137.7, respectively.

Effects of selenium deficiency on principal indexes of chicken kidney function.

Selenium (Se) deficiency leads to many pathological changes in animals. However, there have been very few reports regarding chicken tissue injury in the kidney caused by Se deficiency. In this study, a chicken Se-deficient disease model has been constructed, and two renal function indexes [including creatinine (CREA) and uric acid (URIC)], seven renal antioxidative function indexes [including glutathione peroxidase (GPx), anti-hydroxyl radical (AHR), catalase (CAT), hydrogen peroxide (H2O2), nitrogen monoxide (NO), glutathione (GSH), and malonyldialdehyde (MDA)], and two organ/tissue injury-related indexes [including inducible nitric oxide synthase (iNOS) and inducible heme oxygenase (HO)-1] were detected and analyzed to investigate the effects of Se deficiency on chicken kidney tissue. The results showed that Se deficiency caused a significant increase in CREA and URIC levels and a decrease in renal antioxidative capacity. Meanwhile, Se deficiency upregulated the expression of organ/tissue injury-related genes, such as the messenger RNA (mRNA) of HO-1 and iNOS as well as their protein expression levels, in the chicken kidney tissue. These data suggest that Se deficiency in birds triggers renal function regression and oxidative stress in the kidney tissue.

[Impact on the gait time cycle of ischemic stroke in the treatment with yin-yang respiratory reinforcing and reducing needling technique].

OBJECTIVE: To compare the difference in the efficacy on gait time cycle of ischemic stroke between yin-yang respiratory reinforcing and reducing needling technique (yin-yang needling) and the conventional acupuncture. METHODS: Sixty cases of ischemic stroke were randomized into a conventional acupuncture group and a yin-yang needling group, 30 cases in each one. The basic treatment (the control of blood pressure, blood sugar and blood lipid, the intravenous drops of ginkgo leaf extract and dipyridamole injection and vinpocetine injection) were applied in the two groups. Additionally, in the conventional acupuncture group, the acupoints of the Stomach Meridian of Foot-Yangming [Biguan (ST 31), Liangqiu (ST 34), Zusanli (ST 36), Shangjuxu (ST 37), Xiajuxu (ST 39), etc.] were selected and stimulated with the even needling technique. In the yin-yang needling group, the acupoints of yin meridians such as Zuwuli (LR 10), Xuehai (SP 10), Yinlingquan (SP 9) and Sanyinjiao (SP 6), etc. and the acupoints of yang meridians such as Biguan (ST 31), Liangqiu (ST 34) and Yanglingquan (GB 34), etc. were selected. The reducing manipulation of respiratory reinforcing and reducing technique was applied to the acupoints of yin meridians and the reinforcing manipulation was applied to the acupoints of yang meridians. The kinematics time parameters were determined and compared before and 4 weeks after treatment. RESULTS: After treatment, the differences in the gait cycle, the phase time of standing (%), the phase time of single support (%), the phase time of unilateral sway (%) on the affected (healthy) foot and phase time of double support (%) were significant as compared with those before treatment in the patients of the two groups (all P < 0.05), in which, the gait cycle (1.75 +/- 0.21 vs 2.02 +/- 0.37), the phase time of standing (%) on the affected (healthy) foot [(65.41 +/- 5.20)% vs (68.37 +/- 6.24)%, (70.99 +/- 6.47)% vs (74.51 +/- 5.19)%], the phase time of unilateral sway (%) on the affected (healthy) foot [(36.08 +/- 4.86)% vs (33.65 +/- 2.94)%, (31.04 +/- 3.41)% vs (26.77 +/- 2.67)%] and the phase time of double support (%) [(36.91 +/- 5.10)% vs (41.22 +/- 5.39)%] in the yin-yang needling group were improved much obviously after treatment as compared with those in the conventional acupuncture group. The differences in support phase time (%), single support phase time (%) and sway phase time (%) were significant between the affected limb and healthy limb of the two groups after treatment (all P < 0.05). CONCLUSION: Yin-yang respiratory reinforcing and reducing needling technique effectively improves hemiplegic gait movement cycle and walking function in patients of ischemic stroke, which is superior to the conventional acupuncture treatment.

[Impacts of yin-yang meridians acupuncture with respiratory reinforcing and reducing manipulation on lower limbs balance function in stroke patients].

OBJECTIVE: To observe the impact on lower limbs balance function in treatment of yin-yang meridians acupuncture with respiratory reinforcing and reducing manipulation involved in the patients of stroke by applying B-PHY balance function test training system so as to provide the objective evidence in treatment of stroke; with acupuncture. METHODS: One hundred patients were randomized into an observation group and a control group, 50 cases in each one. In the control group, the basic treatment was applied, without other relevant rehabilitation therapies associated. In the observation group, with the basic treatment as the control group's, the therapy of the yin-yang meridians acupuncutre with respiratory reinforcing and reducing manipulation was adopted. On the yin meridians, Zuwuli (LR 10), Xuehai (SP 10), Yinlingquan (SP 9), Sanyinjiao (SP 6) and the others were selected and stimulated with reducing manipulation achieved by the coordination of patient's respiration. On the yang meridians, Biguan (ST 31), Liangqiu (ST 34), Yanglingquan (GB 34) and the others were selected and stimulated with reinforcing manipulation achieved by the coordination of patient's respiration. The treatment was given once a day and for 28 days totally. Before treatment and in 28 days of treatment, B-PHY balance function test training system was used to determine the weight shift track parameters (track length, peripheral square, track length of per unit square, left-right offset and rectangle square), the weight shift track distance parameters [mean of X axle weight shift distance (Mean-X), mean of Y axle weight shift distance (Mean-Y), maximum of X axle weight shift distance (Max-X), maximum of Y axle weight shift distance (Max-Y), weight shift distance (LSKG), weight shift square (SSKG), square ratio of weight shift (LFS)], stability coefficient (SI) and weight distribution coefficient (WDI). RESULTS: After treatment, the differences in the weight shift track parameters, SI and WDI were significant as compared with those before treatment in the patients of the two groups (all P<0.01); while the differences in the weight shift distance parameters in the observation group were improved obviously after treatment as compared with those before treatment (all P<0.01), the differences of Mean-X, Max-Y and LFS in the control group were improved after treatment as compared with those before treatment (all P<0.01). Except SSKG, the improvements after treatment in the rest indices in the observation group were better than those in the control group (all P<0.05). CONCLUSION: The yin-yang meridians acupuncture with respiratry reinforcing and re- ducing manipulation effectively improves the lower limbs balance function in the patients of stroke.
