[Comparative analysis of plastomes of Rubus chingii and R. chingii var. suavissimus].

Rubus chingii and R. chingii var. suavissimus are unique dual-purpose plant resources, with significant nutraceutical, pharmaceutical, and economic value, as well as promising prospects for further development. To investigate the genetic structure and evolutionary characteristics of these two varieties, this study conducted plastome sequencing using the Illumina HiSeq XTen sequencing platform. Subsequently, the study performed assembly, annotation, and characterization of the genomes, followed by a comparative plastome and phylogenetic analysis using bioinformatics techniques. The results revealed that the plastomes of R. chingii and R. chingii var. suavissimus exhibited a tetrad structure, comprising a large single-copy region(LSC), a small single-copy region(SSC), and two inverted repeat regions(IRs). The study identified a total of 56 simple sequence repeats(SSRs) after comparative analysis, predominantly consisting of A and T. Furthermore, the structure of the IR boundary genes in both varieties was found to be highly conserved, with only minor nucleotide variations. Additionally, the study identified three highly variable regions: rps16-trnQ-psbK, trnR-atpA, and trnT-trnL, which held promise as potential identification marks for further development and utilization. Phylogenetic analysis results obtained by the maximum likelihood and Bayesian inference methods demonstrated a close clustering of R. chingii and R. chingii var. suavissimus(100% support), with their closest relatives being R. trianthus. This study, focusing on plastome-level genetic distinctions between these two varieties, lays a foundation for future species protection, development, and utilization.

Glutamine enhances sucrose taste through a gut microbiota-gut-brain axis in Drosophila.

AIMS: Amino acids (AAs) are known to play important roles in various physiological functions. However, their effect on sweet taste perception remains largely unknown. MAIN METHODS: We used Drosophila to evaluate the effect of each AA on sucrose taste perception. Individual AA was supplemented into diets and male flies were fed on these diets for 6 days. The proboscis extension response (PER) assay was applied to assess the sucrose taste sensitivity of treated flies. We further utilized the RNA-seq and germ-free (GF) flies to reveal the underlying mechanisms of sucrose taste sensitization induced by glutamine (Gln). KEY FINDINGS: We found that supplementation of Gln into diets significantly enhances sucrose taste sensitivity. This sucrose taste sensitization is dependent on gut microbiota and requires a specific gut bacterium Acetobacter tropicalis (A. tropicalis). We further found that CNMamide (CNMa) in the gut and CNMa receptor (CNMaR) in dopaminergic neurons are required for increased sucrose taste sensitivity by Gln diet. Finally, we demonstrated that a gut microbiota-gut-brain axis is required for Gln-induced sucrose taste sensitization. SIGNIFICANCE: These findings can advance understanding of the complex interplay between host physiology, dietary factors, and gut microbiota.

Natural compounds as obesity pharmacotherapies.

Obesity has become a serious global public health problem, affecting over 988 million people worldwide. Nevertheless, current pharmacotherapies have proven inadequate. Natural compounds have garnered significant attention due to their potential antiobesity effects. Over the past three decades, ca. 50 natural compounds have been evaluated for the preventive and/or therapeutic effects on obesity in animals and humans. However, variations in the antiobesity efficacies among these natural compounds have been substantial, owing to differences in experimental designs, including variations in animal models, dosages, treatment durations, and administration methods. The feasibility of employing these natural compounds as pharmacotherapies for obesity remained uncertain. In this review, we systematically summarized the antiobesity efficacy and mechanisms of action of each natural compound in animal models. This comprehensive review furnishes valuable insights for the development of antiobesity medications based on natural compounds.

Nutritional geometry framework of sucrose taste in Drosophila.

Dietary protein (P) and carbohydrate (C) have a major impact on the sweet taste sensation. However, it remains unclear whether the balance of P and C influences the sweet taste sensitivity. Here, we use the nutritional geometry framework (NGF) to address the interaction of protein and carbohydrates on sweet taste using Drosophila as a model. Our results reveal that high-protein, low-carbohydrate (HPLC) diets sensitize to sweet taste and low-protein, high-carbohydrate (LPHC) diets desensitize sweet taste in both male and female flies. We further investigate the underlying mechanisms of the effects of two diets on sweet taste using RNA sequencing. When compared to the LPHC diet, the mRNA expression of genes involved in the metabolism of glycine, serine, and threonine is significantly upregulated in the HPLC diet group, suggesting these amino acids may mediate sweet taste perception. We further find that sweet sensitization occurs in flies fed with the LPHC diet supplemented with serine and threonine. Our study demonstrates that sucrose taste sensitivity is affected by the balance of dietary protein and carbohydrates possibly through changes in serine and threonine.

Ginseng volatile oil prolongs the lifespan and healthspan of Caenorhabditis elegans.

Ginseng volatile oil (GVO) is one of the main components of ginseng and has antibacterial and anti-inflammatory properties. In this study, gas chromatography-mass spectrometry (GC-MS) was applied to characterize GVO chemical composition, and 73 volatile components were detected from GVO. Caenorhabditis elegans was used as animal model to further elucidate the antioxidant and anti-aging effects of GVO in vivo. The results suggested that GVO significantly prolonged the lifespan of C. elegans and promoted its health without damaging its reproductive capacity. In addition, GVO increased the antioxidant capacity and survival rate of nematodes after heat shock. Transcriptional sequencing showed that autophagy-related genes atg-4.2, atg-7, lgg-2, and cyd-1 were up-regulated, and superoxide dismutase 1 (sod-1) expression was increased after GVO pretreatment. Considering the role of autophagy and antioxidant in aging, the expression of autophagy substrate P62 protein in BC12921 strain was analyzed and found to decrease by more than 50.00% after treatment with GVO. In addition, the lifespan of SOD-1 mutant nematodes was not significantly different from that of the control group. SOD activity and autophagy were activated, which is a clear expression of hormesis. All these results suggest that GVO prolongs the lifespan and healthspan of C. elegans, and its biological functions may be related to hormesis.

Phylogenomics and Genetic Diversity of Arnebiae Radix and Its Allies (Arnebia, Boraginaceae) in China.

Arnebiae Radix is a traditional medicine with pleiotropic properties that has been used for several 100 years. There are five species of Arnebia in China, and the two species Arnebia euchroma and Arnebia guttata are the source plants of Arnebiae Radix according to the Chinese Pharmacopoeia. Molecular markers that permit species identification and facilitate studies of the genetic diversity and divergence of the wild populations of these two source plants have not yet been developed. Here, we sequenced the chloroplast genomes of 56 samples of five Arnebia species using genome skimming methods. The Arnebia chloroplast genomes exhibited quadripartite structures with lengths from 149,539 and 152,040 bp. Three variable markers (rps16-trnQ, ndhF-rpl32, and ycf1b) were identified, and these markers exhibited more variable sites than universal chloroplast markers. The phylogenetic relationships among the five Arnebia species were completely resolved using the whole chloroplast genome sequences. Arnebia arose during the Oligocene and diversified in the middle Miocene; this coincided with two geological events during the late Oligocene and early Miocene: warming and the progressive uplift of Tianshan and the Himalayas. Our analyses revealed that A. euchroma and A. guttata have high levels of genetic diversity and comprise two and three subclades, respectively. The two clades of A. euchroma exhibited significant genetic differences and diverged at 10.18 Ma in the middle Miocene. Three clades of A. guttata diverged in the Pleistocene. The results provided new insight into evolutionary history of Arnebia species and promoted the conservation and exploitation of A. euchroma and A. guttata.

[Evaluation of genetic diversity of ginseng fruit color germplasm resources: based on SSR analysis].

Illumina Xten was employed for shallow sequencing of Panax ginseng(ginseng) samples, MISA for screening of SSR loci, and Primer 3 for primer design. Polymorphic primers were screened from 180 primers. From the successfully amplified polymorphic primers, 15 primers which featured clear peak shape, good polymorphism, and ease of statistics were selected and used to evaluate the genetic diversity and germplasm resources of 36 ginseng accessions with different fruit colors from Jilin province. The results showed that red-fruit ginseng population had high genetic diversity with the average number of alleles(N_a) of 1.031 and haploid genetic diversity(h) of 0.172. The neighbor-joining cluster analysis demonstrated that the germplasms of red-fruit and yellow-fruit ginseng populations were obviously intermixed, and pick-fruit ginseng germplasms clustered into a single clade. The results of STRUCTURE analysis showed high proportion of single genotype in pick-fruit ginseng germplasm and abundant genotypes in red-fruit and yellow-fruit ginseng germplasms with obvious germplasm mixing. AMOVA revealed that genetic variation occurred mainly within populations(62.00%, P<0.001), and rarely among populations(39%, P<0.001), but homogenization was obvious among different populations. In summary, pink-fruit ginseng population may contain rare genotypes, which is the basis for breeding of high-quality high-yield, and multi-resistance varieties, genetic improvement of varieties, and sustainable development and utilization of ginseng germplasm resources.

Heterogeneous Genetic Diversity Estimation of a Promising Domestication Medicinal Motherwort Leonurus Cardiaca Based on Chloroplast Genome Resources.

Leonurus cardiaca has a long history of use in western herbal medicine and is applied for the treatment of gynaecological conditions, anxiety, and heart diseases. Because of its botanical relationship to the primary Chinese species, L. japonicus, and extensive medical indications that go beyond the traditional indications for the Chinese species, it is a promising medicinal resource. Therefore, the features of genetic diversity and variability in the species have been prioritized. To explore these issues, we sequenced the chloroplast genomes of 22 accessions of L. cardiaca from different geographical locations worldwide using high-throughput sequencing. The results indicate that L. cardiaca has a typical quadripartite structure and range from 1,51,236 bp to 1,51,831 bp in size, forming eight haplotypes. The genomes all contain 114 distinct genes, including 80 protein-coding genes, 30 transfer RNA genes and four ribosomal RNA genes. Comparative analysis showed abundant diversity of single nucleotide polymorphisms (SNPs), indels, simple sequence repeats (SSRs) in 22 accessions. Codon usage showed highly similar results for L. cardiaca species. The phylogenetic and network analysis indicated 22 accessions forming four clades that were partly related to the geographical distribution. In summary, our study highlights the advantage of chloroplast genome with large data sets in intraspecific diversity evaluation and provides a new tool to facilitate medicinal plant conservation and domestication.

Chinese herbal medicines are expected to be developed as antiaging drugs or used in the medical cosmetology industry.

Therapeutic effect of oxyberberine on obese non-alcoholic fatty liver disease rats.

BACKGROUND: Berberine (BBR) has been widely used to treat non-alcoholic fatty liver disease (NAFLD). The metabolites of BBR were believed to contribute significantly to its pharmacological effects. Oxyberberine (OBB), a gut microbiota-mediated oxidative metabolite of BBR, has been firstly identified in our recent work. PURPOSE: Here, we aimed to comparatively investigate the anti-NAFLD properties of OBB and BBR. METHODS: The anti-NAFLD effect was evaluated in high-fat diet-induced obese NAFLD rats with biochemical/ELISA tests and histological staining. The related gene and protein expressions were detected by qRT-PCR and Western blotting respectively. Molecular docking and dynamic simulation were also performed to provide further insight. RESULTS: Results indicated OBB remarkably and dose-dependently attenuated the clinical manifestations of NAFLD, which (100 mg/kg) achieved similar therapeutic effect to metformin (300 mg/kg) and was superior to BBR of the same dose. OBB significantly inhibited aberrant phosphorylation of IRS-1 and up-regulated the downstream protein expression and phosphorylation (PI3K, p-Akt/Akt and p-GSK-3ß/GSK-3ß) to improve hepatic insulin signal transduction. Meanwhile, OBB treatment remarkably alleviated inflammation via down-regulating the mRNA expression of MCP-1, Cd68, Nos2, Cd11c, while enhancing Arg1 mRNA expression in white adipose tissue. Moreover, OBB exhibited closer affinity with AMPK in silicon and superior hyperphosphorylation of AMPK in vivo, leading to increased ACC mRNA expression in liver and UCP-1 protein expression in adipose tissue. CONCLUSION: Taken together, compared with BBR, OBB was more capable of maintaining lipid homeostasis between liver and WAT via attenuating hepatic insulin pathway and adipocyte inflammation, which was associated with its property of superior AMPK activator.

[Effect of intranasal acupuncture on neurogenic inflammation in allergic rhinitis rabbits].

OBJECTIVE: To observe the effect of intranasal acupuncture on allergic rhinitis (AR), and expression of substance P (SP), vasoactive intestinal peptide (VIP) and neuropeptide Y (NPY) proteins in the nasal mucosa and contents of serum immunoglobulin E (IgE), interleukin 4 (IL-4) and interferon-γ (IFN-γ) in AR rabbits, so as to explore its mechanisms underlying improvement of AR. METHODS: New Zealand rabbits were randomly divided into normal control, AR model, non-acupuoint acupuncture (NAA) and intranasal acupuncture (INA) groups, with 8 rabbits in each group. The AR model was established by intra-peritoneal injection of egg protein and nasal mucosal stimulation. In the INA group, bilateral "Neiyingxiang" (EX-HN9) within the nasal cavity (the anterior attachment area of the inferior turbinate, about 1 cm away from the nasal limen) were acupunctured by mani-pulating the filiform needles for a while with uniform reinforcing and reducing methods, followed by keeping the needles for 20 min. In the NAA group, shallow acupuncture was applied to the skin of the outer margin of the cheeks, followed by keeping the needle for 20 min. The acupuncture treatment was conducted once every other day for 7 days. The symptoms of sneezing frequency, nasal secretion amount and nasal itching were scored. The expression levels of SP, VIP and NPY in the nasal mucosa tissue were detected by immunohistochemistry, and the serum IgE, IL-4, and IFN-γ contents were detected by ELISA. RESULTS: After modelling, the symptom score, expression of SP and VIP, and serum IgE and IL-4 contents were significantly higher (P<0.01,P<0.05), NPY expression and serum IFN-γ content significantly lower (P<0.05, P<0.01) in the model group than in the normal control group. Following the intervention, the symptom scores, expressions of SP and VIP, and serum IgE and IL-4 contents were remarkably decreased (P<0.05, P<0.01), while the NPY expression and serum IFN-γ content were significantly up-regulated (P<0.05, P<0.01) in the INA group than in the model group. The effects of INA group were significantly superior to those of NAA group in reducing symptom score, SP and VIP expression, and serum IgE and IL-4 contents and up-regulating NPY expression and IFN-γcontent (P<0.05, P<0.01). There were a positive correlation between the expressions of SP and VIP and contents of serum IgE and IL-4 (P<0.05), and a negative correlation between the expressions of SP and VIP and IFN-γ content (P<0.05). CONCLUSION: INA treatment can relieve symptoms of AR in AR rabbits, which may be associated with its effects in regulating the expression of SP, VIP and NPY of the nasal mucosa, and contents of serum IgE, IL-4 and IFN-γ to improve neurogenic inflammation.

Alpha-Lipoic Acid Attenuates Cadmium- and Lead-Induced Neurotoxicity by Inhibiting Both Endoplasmic-Reticulum Stress and Activation of Fas/FasL and Mitochondrial Apoptotic Pathways in Rat Cerebral Cortex.

Although many studies have reported toxic effects of cadmium (Cd) and lead (Pb) in the central nervous system, few studies have investigated the combined toxicity of Cd and Pb. The mechanisms by which these combined heavy metals induce toxicity, as well as effective means to exert neuroprotection from these agents, remain poorly understood. To investigate the protective effects of alpha-lipoic acid (α-LA) on Cd- and/or Pb-induced cortical damage in rats, 48 Sprague-Dawley rats were exposed to drinking water containing 50 mg/L of Cd and/or 300 mg/L of Pb for 12 weeks, in the presence or absence of α-LA co-treatment (50 mg/kg) via gavage. We observed that exposure to Cd and/or Pb decreased the brain weight/body weight ratio and increased Cd and/or Pb contents as well as ultrastructural damage to the cerebral cortex. Cd and/or Pb also induced endoplasmic-reticulum (ER) stress and activated Fas (CD95/APO-1)/Fas ligand (FasL) and mitochondrial apoptotic pathways. Furthermore, co-treatment of Cd and Pb further exacerbated part of these phenotypes than treatment of Cd or Pb alone. However, simultaneous supplementation with α-LA attenuated Cd and/or Pb-induced neurotoxicity by increasing the brain weight/body weight ratio, reducing Cd and/or Pb contents, ameliorating both nuclear/mitochondrial damage and ER stress, and attenuating activation of Fas/FasL and mitochondrial apoptotic pathways. Collectively, our results indicate that the accumulation of Cd and/or Pb causes cortical damage and that α-LA exerts protection against Cd- and/or Pb-induced neurotoxicity. These findings highlight that α-LA may be exploited for the treatment and prevention of Cd- and/or Pb-induced neurotoxicity.

Branched chain amino acids impact health and lifespan indirectly via amino acid balance and appetite control.

Elevated branched chain amino acids (BCAAs) are associated with obesity and insulin resistance. How long-term dietary BCAAs impact late-life health and lifespan is unknown. Here, we show that when dietary BCAAs are varied against a fixed, isocaloric macronutrient background, long-term exposure to high BCAA diets leads to hyperphagia, obesity and reduced lifespan. These effects are not due to elevated BCAA per se or hepatic mTOR activation, but rather due to a shift in the relative quantity of dietary BCAAs and other AAs, notably tryptophan and threonine. Increasing the ratio of BCAAs to these AAs resulted in hyperphagia and is associated with central serotonin depletion. Preventing hyperphagia by calorie restriction or pair-feeding averts the health costs of a high BCAA diet. Our data highlight a role for amino acid quality in energy balance and show that health costs of chronic high BCAA intakes need not be due to intrinsic toxicity but, rather, a consequence of hyperphagia driven by AA imbalance.

Therapeutic effect of Brucea javanica oil emulsion on experimental Crohn's disease in rats: Involvement of TLR4/ NF-κB signaling pathway.

Brucea javanica is an important Chinese folk medicine traditionally used for the treatment of dysentery (also known as inflammatory bowel diseases). Brucea javanica oil emulsion (BJOE), the most common preparation of Brucea javanica, has a variety of pharmacological activities. In this follow-up investigation, we endeavored to illuminate the potential benefit of BJOE on 2, 4, 6-trinitrobenzenesulfonic acid (TNBS)-induced Crohn's disease (CD) in rats and decipher the mechanism of action. The result illustrated that BJOE treatment significantly reduced the body weight loss, disease activity index and macroscopic scores, ameliorated shortening of colon length, arrested colonic histopathological deteriorations, lowered the histological scores in parallel to the model group. Furthermore, BJOE also decreased the levels of MPO and pro-inflammatory cytokines (TNF-α, IL-1ß, IL-6, IL-17, IL-23 and IFN-γ), and increased the levels of anti-inflammatory cytokines (IL-4, IL-10 and TGF-ß) as compared with the model group. In addition, the elevated mRNA expression of MMP-1, MMP-3 and RAGE induced by TNBS was remarkably inhibited by BJOE, SASP or AZA treatments, while the mRNA expression of PPAR-γ was significantly enhanced. Furthermore, the activation of TLR4/NF-κB signaling pathway was significantly inhibited by AZA and BJOE treatment when compared with that of TNBS-treated rats. Our study suggested that BJOE exerted superior therapeutic effect to SASP and AZA in treating TNBS-induced colitis in rats. The protective effect of BJOE may involve the inhibition of the TLR4/NF-κB-mediated inflammatory responses. These results indicated that BJOE held promising potential to be further developed into a novel candidate for the treatment of CD.

Secretory overproduction of a raw starch-degrading glucoamylase in Penicillium oxalicum using strong promoter and signal peptide.

Raw starch-degrading enzymes (RSDEs) are capable of directly degrading raw starch granules below the gelatinization temperature of starch, which may significantly reduce the cost of starch-based biorefining. However, low yields of natural RSDEs from filamentous fungi limit their industrial application. In this study, transcriptomic and secretomic profiling was employed to screen strongest promoters and signal peptides for use in overexpression of a RSDE gene in Penicillium oxalicum. Top five strong promoters and three signal peptides were detected. Using a green fluorescent protein (GFP) as the reporter, the inducible promoter pPoxEgCel5B of an endoglucanase gene PoxEgCel5B and the signal peptide spPoxGA15A of a raw starch-degrading glucoamylase PoxGA15A were respectively identified as driving the highest GFP production in P. oxalicum. PoxGA15A-overexpressed P. oxalicum strain OXPoxGA15A, which was constructed based on both pPoxEgCel5B and spPoxGA15A, produced significantly higher amounts of recombinant PoxGA15A than the parental strain ∆PoxKu70. Furthermore, crude enzyme from the OXPoxGA15A strain exhibited high activities towards raw starch from cassava, potato, and uncooked soluble starch. Specifically, raw cassava starch-degrading enzyme activity reached 241.6 U/mL in the OXPoxGA15A, which was 3.4-fold higher than that of the ∆PoxKu70. This work provides a feasible method for hyperproduction of RSDEs in P. oxalicum.

Sucralose Promotes Food Intake through NPY and a Neuronal Fasting Response.

Non-nutritive sweeteners like sucralose are consumed by billions of people. While animal and human studies have demonstrated a link between synthetic sweetener consumption and metabolic dysregulation, the mechanisms responsible remain unknown. Here we use a diet supplemented with sucralose to investigate the long-term effects of sweet/energy imbalance. In flies, chronic sweet/energy imbalance promoted hyperactivity, insomnia, glucose intolerance, enhanced sweet taste perception, and a sustained increase in food and calories consumed, effects that are reversed upon sucralose removal. Mechanistically, this response was mapped to the ancient insulin, catecholamine, and NPF/NPY systems and the energy sensor AMPK, which together comprise a novel neuronal starvation response pathway. Interestingly, chronic sweet/energy imbalance promoted increased food intake in mammals as well, and this also occurs through an NPY-dependent mechanism. Together, our data show that chronic consumption of a sweet/energy imbalanced diet triggers a conserved neuronal fasting response and increases the motivation to eat.

[Triple-strong stimulation therapy at Dazhui (GV 14) in prevention and treatment of children allergic rhinitis: a randomized controlled trial].

OBJECTIVE: To evaluate the short-term efficacy and long-term preventive effect on recurrence in prevention and treatment of children allergic rhinitis treated with the multiple therapy at Dazhui (GV 14) as the main acupoint and acupoint plaster therapy. METHODS: One hundred and twenty cases of children allergic rhinitis were randomized into a triple-strong stimulation therapy group and an acupoint plaster therapy group, 60 cases in each one. In the triple-strong stimulation therapy group, Dazhui (GV 14) was the main acupoint, combined with one of Feishu (BL 13), Zhiyang (GV 9) and Shenshu (BL 23) accordingly. The heavy needling technique was adopted with the three-edged needle, followed by heavy cupping and heavy moxibustion. The treatment was given once every 3 days, continuously for 10 times. In the acupoint plaster therapy group, the acupoints selected were same as the triple-strong stimulation therapy group. The self-prepared Chinese herbal plaster was used, 4 h to 8 h each one time, once every 3 days, continuously for 10 times. The changes in the symptom and physical sign scores were observed before treatment, after treatment and in 6 months follow-up visit after treatment in the two groups. The clinical efficacy was compared between the two groups. RESULTS: After treatment and in 6 months follow-up visit after treatment, the symptom scores, physical sign scores and symptom scores of each item were different signi ficantly as compared with those before treatment in the triple-strong stimulation therapy group (P<0.01, P<0.05), and the results in the triple-strong stimulation therapy group were better than those in the acupoint plaster therapy group (all P<0.01). In 6 months follow-up visit, the total effective rate was 94.6% (53/56) in the triple-strong stimulation therapy group and was 25.9% (15/58) in the acupoint plaster therapy group, indicating the significant difference (P<0.001). CONCLUSION: The triple-strong stimulation therapy at Dazhui (GV 14) achieves the superior effect on the prevention and treatment of children allergic rhinitis as compared with the acupoint plas ter therapy and has good long-term effect of the prevention from recurrence.

[Impacts on the lower limb motor function in children with spastic cerebral palsy treated by Jin three-needle therapy combined with MOTOmed intelligent motor training].

OBJECTIVE: To compare the differences in the efficacy on lower limb motor function in children with spastic cerebral palsy between the combined therapeutic program of Jin three-needle therapy and MOTOmed intelligent motor training and the simple MOTOmed. METHODS: Eighty children with spastic cerebral palsy were randomized into an observation group and a control group, 40 cases in each group. In the observation group, Jin three-needle therapy was used at four mind points, three brain points, three intelligent points, three temporal points, three knee points and three foot points, as well as Chengjin (BL 56), Chengshen (BL 57) and the other. Additionally, MOTOmed was given in assistance with conventional rehabilitation training. In the control group, MOTOmed and the conventional rehabilitation training were adopted. In the two groups, the treatment was given once a day, 20 treatments made one session and there were 3 to 5 days at interval between the two sessions. The efficacy evaluation was performed after continuous 3 sessions of treatment. The gross motor function measure (GMFM) and modified Ashworth scale (MAS) were applied for the evaluation before and after treatment in the two groups. RESULTS: After 3 sessions of treatment, GMFM score was increased apparently as compared with that before treatment in the two groups (P < 0.01, P < 0.05). After treatment, GMFM score in the observation group was increased more remarkably than that in the control group (55.32 +/- 17.10 vs 47.48 +/- 17.18, P < 0.05). After treatment, the total effective rate of gastrocnemius Ashworth spasm grade [90.0% (36/40)] in the observation group was better apparently than [72.5% (29/40)] in the control group (P < 0.05). CONCLUSION: The combined therapeutic program of Jin three-needle therapy and MOTOmet intelligent motor training improves the lower limb motor function of the children with spastic cerebral palsy and its efficacy is better than simple MOTOmed.

[Effect of Spearmint oil on inflammation, oxidative alteration and Nrf2 expression in lung tissue of COPD rats].

OBJECTIVE: To investigate the effect of Spearmint oil on inflammation, oxidative alteration and Nrf2 expression in rats with chronic obstructive pulmonary disease(COPD). METHODS: COPD model was induced by intratracheal instillation of Klebsiella pneumonia and lipopolysaccharide (LPS) for 12 weeks in rats, and COPD rats were treated with Spearmint oil for 3 weeks. After COPD was induced, the pathological changes, changes in leucocyte number in blood and bronchoalveolar lavage fluid (BALF), MDA in lung homogenate and Nrf2 expression were observed. The effects of Spearmint oil on these changes were determined. RESULT: Spearmint oil 100 mg*kg(-1)significantly reduced leucocyte numbers in BALF, and attenuated bronchiolitis, pulmonary interstitial inflammation and inflammation cell infiltration. Spearmint oil 30-300 mg*kg(-1)decreased the destruction of pulmonary alveolus and the thickness of bronchioles walls, and inhibited goblet cell proliferation. Spearmint oil significantly reduced MDA in lung homogenate, and decreased the expression of Nrf2 protein in lung tissues. CONCLUSION: Spearmint oil has protective effect on lung injury in COPD rats, since it improves pulmonary inflammation,oxidative alteration, and enhances Nrf2 protein expression.
