Modulating the RFamide-related peptide-3/G protein-coupled receptor 147 signaling pathway with nourishing Yin-removing fire herbal mixture to alleviate precocious puberty in female rats: An experimental study.

Background: Precocious puberty (PP) involves early activation of the hypothalamic gonadotropin-releasing hormone (GnRH) generator. The RFamide-related peptide/G protein-coupled receptor 147 (RFRP3/GPR147) signaling pathway is vital in inhibiting GnRH and delaying puberty onset. The nourishing Yin-removing fire (NYRF) herbal mixture has shown promising results in treating PP. Objective: This study aimed to assess the impact of the NYRF herbal mixture on the RFRP3/GPR147 signaling pathway in the hypothalamus and its potential in alleviating PP in female rats. Materials and Methods: In a controlled experiment, 24 female Sprague-Dawley rats (11.20 ± 0.69 gr, postnatal day [PD5]) were divided into normal, model, normal saline, and NYRF groups (n = 6/each). PP was induced in the model, normal saline, and NYRF groups by subcutaneous injection of danazol at PD5. The NYRF herbal mixture or normal saline was administered from PD15. Serum sex hormone levels and hypothalamic samples were collected for mRNA and protein expression at PD30. Results: In the model group, hypothalamic GnRH and kisspeptin levels increased, while RFRP3 and GPR147 levels decreased, luteinizing hormone levels elevated, reproductive organ coefficients increased, and the vagina opened earlier compared to the normal group. Conversely, the NYRF group exhibited lower GnRH and kisspeptin levels but higher RFRP3 levels in the hypothalamus. Serum luteinizing hormone levels were reduced, reproductive organ coefficients were reduced, and the vaginal opening was delayed compared to the model and normal saline groups. Conclusion: The NYRF herbal mixture delayed sexual development in rats with PP by hypothalamic upregulating RFRP3 and downregulating GnRH and kisspeptin.

The paper introduces CHEN Rixin's experience and ideas of heat-sensitive moxibustion for Wenyang Yangshen (warming-up yang and nourishing the spirit) in treatment of insomnia of yang deficiency. This type of insomnia is caused by yang insufficiency of the body and malnutrition of the spirit. The treatment focuses on Wenyang Yangshen. Replenishing yang (Shenque [CV 8], Qihai [CV 6] and Guanyuan [CV 4]) is combined with promoting yang circulation (Taiyang [EX-HN 5]). The acupoint combination is optimized through identifying the heat sensitivity. Sparrow-pecking moxibustion and mild moxibustion are used to control the appropriate moxibustion temperature, efficiently stimulate deqi and individually saturate the dose of moxibustion so as to target the principle of treatment and improve the sleep quality.

Nourishing Yin traditional Chinese medicine: potential role in the prevention and treatment of type 2 diabetes.

Type 2 diabetes mellitus (T2DM), a common and frequently occurring disease in contemporary society, has become a global health threat. However, current mainstream methods of prevention and treatment, mainly including oral hypoglycemic drugs and insulin injections, do not fundamentally block the progression of T2DM. Therefore, it is imperative to find new ways to prevent and treat diabetes. Traditional Chinese medicine is characterized by multiple components, pathways, and targets with mild and long-lasting effects. Pharmacological studies have shown that nourishing yin traditional Chinese medicine (NYTCM) can play a positive role in the treatment of T2DM by regulating pathways such as the phosphatidylinositol 3-kinase/serine-threonine kinase, mitogen-activated protein kinase, nuclear factor-kappa B, and other pathways to stimulate insulin secretion, protect and repair pancreatic ß cells, alleviate insulin resistance, ameliorate disordered glucose and lipid metabolism, mitigate oxidative stress, inhibit inflammatory responses, and regulate the intestinal flora. The pharmacologic activity, mechanisms, safety, and toxicity of NYTCM in the treatment of T2DM are also reviewed in this manuscript.

Effect of nourishing and purging fire Chinese herbal mixture on delaying light-induced premature puberty in rats.

OBJECTIVE: To elucidate the mechanism of the nourishing Yin and purging fire Chinese herbal mixture (NYPF) in delaying light-induced premature puberty in rats. METHODS: Twenty-one days old female Sprague-Dawley rats were randomly assigned to normal group (N), long light exposure group (L), NYPF and normal saline group (NS). Rats in the L, NYPF and NS groups were exposed to 16 h: 350 lux light/8 h: dark, while rats in the N group were exposed to 12 h: 50 lux light/12 h: dark. NYPF and normal saline was administered to the rats in the NYPF group or NS group, respectively, from day 21. Five rats in every group were sacrificed at 9 p.m. on day 28 (P28), on the day when rat's vulva opened in the L group (L-VO), on the day when the first estrous interphase occurred in rats of L group (L-E1), and on the day when the second estrous interphase occurred in rats of L group (L-E2), respectively. RESULITS: On day 34, all rats in the L group, 80% of rats in the NS group, 40% of rats in the N group, and 20% of rats in the NYPF group showed complete opening of the vulva. At P28, mRNA level of hypothalamic kisspeptin (Kiss-1) in the L group was significantly higher than that in the N group (P < 0.05). The rats in the L and NS groups had significantly lower hypothalamic arginine-phenylalanine-amide (RFamide)-related peptide 3 (RFRP-3) mRNA levels than those in the N group (P < 0.05), whereas RFRP-3 mRNA level was significantly higher in the NYPF group than that in the L group (P < 0.05). At L-VO, the ovarian index of the L and NS groups was significantly higher than that of the N group (P < 0.05) and estradiol (E2) level of the NYPF group was significantly lower than that of the N and NS groups (P < 0.05); hypothalamic Kiss-1 mRNA level in the L and NS groups was significantly higher than that in the N and NYPF groups (P < 0.05), whereas hypothalamic RFRP-3 mRNA level in the L, NYPF, and NS groups was significantly lower than that in the N group (P < 0.05). At L-E1, E2 level of the L and NS groups was significantly higher than that of the N group (P < 0.01), whereas it was significantly lower in the NYPF group than that of the N, L, and NS groups (P < 0.01), and serum luteinizing hormone level of the L and NS groups was significantly higher than that of the N group (P < 0.05); levels of serum melatonin and ovarian melatonin receptor 1 (MT-1) mRNA in the L, NYPF, and NS groups were significantly lower than those in the N group (P < 0.05). At L-E2, the uterine organ index of the NYPF group was significantly lower than that of the L group (P < 0.05); and ovarian MT-1 mRNA level of the L and NS groups was significantly lower than that in the N group (P < 0.05). CONCLUSIONS: NYPF can delay puberty onset in rats exposed to strong light for a prolonged duration, and regulation of the gene expression of Kiss-1 and RFRP-3 in the hypothalamus has been suggested as one of the mechanisms.

Lessons for strengthening policymaking for obesity and diet-related noncommunicable disease prevention: A narrative synthesis of policy literature from the Western Pacific Region.

Obesity and diet-related noncommunicable diseases (NCDs) have a profound impact on individuals, households, health care systems, and economies in low- and middle- income countries (LMICs), with the Western Pacific Region experiencing some of the highest impacts. Governments have committed to improving population diets; however, implementation challenges limit effective policy action. We undertook meta-narrative synthesis of the academic literature and used theories of policymaking and implementation to synthesize current knowledge of issues affecting the adoption and implementation of policies to prevent obesity and diet-related NCDs in LMICs in the Western Pacific Region. We found that political leadership and management of food and nutrition policies often diluted following policy adoption, and that nutrition and health advocates find it difficult to enforce policy compliance from actors outside their sectors. Opportunities for strengthening implementation of food and nutrition policies in the Western Pacific include (1) improved and earlier engagement between health policymakers and implementing agencies; (2) focusing on the need for increased accountability from governments, including through effective engagement and organization of actor networks, knowledge sharing, and in highlighting where stronger action is required; and (3) identifying and building the strategic capacities of policy actors in framing, advocacy, coalition-building, knowledge translation, and leadership.

[Gender differences in antidepressant effect of raw Rehmanniae Radix].

For the first time, this study evaluated the gender differences and mechanisms of the antidepressant effects of raw Rehmanniae Radix(RRR) based on the classic depression model with traditional Chinese medicine syndrome of Yin deficiency and internal heat. The depression model with Yin deficiency and internal heat was established by the widely recognized and applied method of thyroxine induction of the classic depression model with Yin deficiency and internal heat(chronic unpredictable mild stress). Male and female mice were simultaneously treated with RRR. The study analyzed indicators of nourishing Yin and clearing heat, conventional antidepressant efficacy test indicators, and important biomolecules reflecting the pathogenesis and prevention and treatment mechanisms of depression, and conducted a correlation analysis of antidepressant efficacy, Yin-nourishing and heat-clearing efficacy, and biological mechanism in different genders, thereby comprehensively assessing the antidepressant effects of RRR on depression of Yin deficiency and internal heat, as well as its gender differences and mechanisms. RRR exhibited antidepressant effects in both male and female mouse models, and its antidepressant efficacy showed gender differences, with a superior effect observed in females. Moreover, the effects of RRR on enhancing or improving hippocampal neuronal pathology, nucleus-positive areas, postsynaptic dense area protein 95, and synaptophysin protein expression were more significant in females than in males. In addition, RRR significantly reversed the abnormal upregulation of nuclear factor(NF)-κB/cyclooxygenase 2(COX2)/NOD-like receptor thermal protein domain associated protein 3(NLRP3) pathway proteins in the hippocampus of both male and female mouse models. The antidepressant effects of RRR were more pronounced in depression female mice with Yin deficiency and internal heat syndrome, possibly due to the improvement of neuronal damage and enhancement of neuroplasticity. The antidepressant mechanisms of RRR for depression with Yin deficiency and internal heat syndrome may be associated with the downregulation of the NF-κB/COX2/NLRP3 pathway to reduce neuronal damage and enhance neuroplasticity.

[Network Meta-analysis of Qi-supplementing and Yin-nourishing Chinese patent medicines in treatment of early diabetic nephropathy].

This study aimed to evaluate the efficacy of Qi-supplementing and Yin-nourishing Chinese patent medicine in the treatment of early diabetic nephropathy(DN) by network Meta-analysis to explore the Chinese patent medicine with optimal efficacy and provide references for preventing renal deterioration and delaying the progression of early DN. Eight databases, including CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library, and Web of Science, were searched for clinical randomized controlled trial(RCT) of Qi-supplementing and Yin-nourishing Chinese patent medicines in the treatment of early DN. After the literature mee-ting the inclusion criteria was screened, the quality of the literature was evaluated using the Cochrane risk-of-bias tool, and network Meta-analysis was performed using the BUGSnet package in R 4.2.1. Seventy-two research articles with a sample size of 6 344 cases were included, involving eight Chinese patent medicines and seven outcome indicators. The results of the network Meta-analysis showed that(1)in terms of improving urinary albumin excretion rate(UAER), Chinese patent medicines combined with conventional treatment were superior to conventional treatment, and Qiyao Xiaoke Capsules + conventional treatment was optimal.(2)In terms of reducing serum crea-tinine(Scr), Bailing Capsules + conventional treatment had superior efficacy.(3)In terms of reducing 24-hour urine total protein(24hUTP), Shenyan Kangfu Tablets + conventional treatment and Jinshuibao Capsules + conventional treatment had equivalent efficacy, and Shenyan Kangfu Tablets + conventional treatment was superior.(4)In terms of improving fasting blood glucose(FBG), Shenyan Kangfu Tablets + conventional treatment had superior efficacy.(5)In terms of improving total cholesterol(TC), Qiyao Xiaoke Capsules +conventional treatment had superior efficacy.(6)In terms of reducing triglyceride(TG), Bailing Capsules + conventional treatment had superior efficacy.(7)In terms of safety, the occurrence of adverse reactions was reported in seven interventions, but due to the large clinical heterogeneity, the quantitative analysis could not be performed. Overall, Qi-supplementing and Yin-nourishing Chinese patent medicines combined with conventional treatment were superior to conventional treatment alone in the treatment of early DN. The results showed that Qi-supplementing and Yin-nourishing Chinese patent medicines combined with conventional treatment had good clinical efficacy, and they could significantly reduce renal function indicators such as UAER, Scr, and 24hUTP, and reduce blood sugar and blood lipid, which can provide evidence-based support for the treatment of early DN. However, due to the differences in the quantity and quality of the included research articles, large-sample, multi-center, high-quality studies are still needed for further verification.

Safe and Durable Treatment of Dentin Hypersensitivity via Nourishing and Remineralizing Dentin Based on ß-Chitooligosaccharide Graft Derivative.

Dentin hypersensitivity (DH) is a common symptom of various dental diseases that usually produces abnormal pain with external stimuli. Various desensitizers are developed to treat DH by occluding dentine tubules (DTs) or blocking intersynaptic connections of dental sensory nerve cells. However, the main limitations of currently available techniques are the chronic toxic effects of chemically active ingredients and their insufficiently durable efficacy. Herein, a novel DH therapy with remarkable biosafety and durable therapeutic value based on ß-chitooligosaccharide graft derivative (CAD) is presented. Particularly, CAD indicates the most energetic results, restoring the amino polysaccharide protective membrane in DTs, significantly promoting calcium and phosphorus ion deposition and bone anabolism, and regulating the levels of immunoglobulin in saliva and cellular inflammatory factors in plasma. Exposed DTs are occluded by remineralized hydroxyapatite with a depth of over 70 µm, as shown in in vitro tests. The bone mineral density of Sprague-Dawley rats' molar dentin increases by 10.96%, and the trabecular thickness of bone improves to about 0.03 µm in 2 weeks in the CAD group compared to the blank group. Overall, the ingenious concept that modified marine biomaterial can be a safe and durable therapy for DH is demonstrated by nourishing and remineralizing dentin.

The regularity of nourishing-yin prescription for treating ascites due to hepatitis B cirrhosis based on data mining technology.

Background: Clinically, Chinese medicine is mostly used to treat ascites due to hepatitis B cirrhosis by nourishing-yin. We summarize the pattern of prescriptions for nourishing-yin inascites due to hepatitis B cirrhosis based on data mining to better use traditional Chinese medicine (TCM) to treat cirrhotic ascites in hepatitis B. Methods: Articles published from 2000 to 2020 on ascites due to hepatitis B cirrhosis were searched in the Chinese National Knowledge Infrastructure and Chinese Science and Technology Journal Database. The results of the search were screened and then treated as the data sources in turn. Based on the data sources, a prescription database of ascites due to hepatitis B cirrhosis was constructed. The data mining was conducted by statistical analysis of frequency and association. Core herbs, including the property and flavor, channel tropism, regularities of medicinal recipes, and core sets, among others, were examined. Results: Through combing 199 articles, a total of 201 prescriptions were selected, involving 138 kinds of herbs. The efficacy of cold herbs was slightly higher than that of warm herbs. The main flavors of herbs were sweet, bitter, and pungent. There were 30 herbs used ≥26 times in 201 prescriptions. The highest frequency of use was Poria cocos, followed by atractylodis macrocephalae, and radix astragali. Ninety-nine commonly used drug combinations were obtained according to the association rules, of which there were 60 associated drug groups with a frequency ≥34, of which the highest frequency was poria cocos-rhizoma atractylodis macrocephalae, poria cocos-oriental water plantain rhizome, poria cocos-radix astragali. Frequent medicinal recipes consisted largely of medicines for tonifying deficiency, including diuretics for eliminating dampness, medicines for promoting blood circulation and removing blood stasis, and supplements for clearing heat and regulating qi. Conclusions: Through data mining, it was found that when TCM treats ascites due to hepatitis B cirrhosis, it attaches importance to using methods of tonifying deficiency and invigorating spleen for diuresis based on nourishing-yin to improve the clinical efficacy, which can provide reference for TCM's clinical use of nourishing-yin to treat ascites due to hepatitis B cirrhosis.

Mechanisms by which kidney-tonifying Chinese herbs inhibit osteoclastogenesis: Emphasis on immune cells.

The immune system plays a crucial role in regulating osteoclast formation and function and has significance for the occurrence and development of immune-mediated bone diseases. Kidney-tonifying Chinese herbs, based on the theory of traditional Chinese medicine (TCM) to unify the kidney and strengthen the bone, have been widely used in the prevention and treatment of bone diseases. The common botanical drugs are tonifying kidney-yang and nourishing kidney-yin herbs, which are divided into two parts: one is the compound prescription of TCM, and the other is the single preparation of TCM and its active ingredients. These botanical drugs regulate osteoclastogenesis directly and indirectly by immune cells, however, we have limited information on the differences between the two botanical drugs in osteoimmunology. In this review, the mechanism by which kidney-tonifying Chinese herbs inhibiting osteoclastogenesis was investigated, emphasizing the immune response. The differences in the mechanism of action between tonifying kidney-yang herbs and nourishing kidney-yin herbs were analysed, and the therapeutic value for immune-mediated bone diseases was evaluated.

[Pharmacological research progress of five classical prescriptions in treatment of chronic heart failure].

Chronic heart failure(CHF) is a comprehensive clinical syndrome caused by multiple factors that result in structural and/or functional abnormalities of the heart, leading to impaired ventricular contraction and/or relaxation functions. This medical condition represents the final stage of various cardiovascular diseases. In the treatment of CHF, multiple clinical studies have demonstrated the benefits of using traditional Chinese medicine(TCM) to control oxidative stress, inflammation, and apoptosis, thereby delaying ventricular remodeling and reducing myocardial fibrosis. In this study, common TCM syndromes in the diagnosis and treatment of CHF in recent years were reviewed and summarized. Five common treatment methods including benefiting Qi and activating blood circulation, enhancing Qi and nourishing Yin, warming Yang for diuresis, eliminating phlegm and dampness, rescuing from collapse by restoring Yang, and corresponding classic prescriptions in prevention and treatment of CHF were concluded under the guidance of TCM syndrome differentiation thinking. Meanwhile, research progress on the modern pharmacological effects of these classic prescriptions was systematically discussed, so as to establish a unique treatment system for CHF by classic prescriptions under the guidance of TCM syndrome differentiation theory and provide innovative diagnosis and treatment strategies for clinical CHF.

Smart Self-Nourishing and Self-Healing Artificial Skin Composite Using Bionic Microvascular Containing Liquid Agent.

Artificial skin composites have attracted great interest in functional composite materials. The aim of this study was to prepare and characterize a smart artificial skin composite comprising a bionic microvascular with both self-nourishing and self-healing functions. A poly(vinyl alcohol)-glycerol-gelatin double network organic hydrogel was used as the artificial skin matrix. The hydrogel had high mechanical strength because of the strong hydrogen bond formed between the PVA and glycerol (GL). The gelatin (GEL) increased the toughness and elasticity of the hydrogel to ensure the strength of the artificial skin and fit of the interface with the body. The bionic polyvinylidene fluoride (PVDF) microvascular had excellent thermal stability and mechanical property in artificial skin. Results indicated that self-nourishing was successfully realized by liquid release through the pore structures of the bionic microvascular. The bionic microvascular healed microcracks in the artificial skin when damage occurred, based on a self-healing test.

Is Chinese herbal formula (nourishing Yin therapy) effective and well tolerated as an adjunct medication to hydroxychloroquine in the treatment of primary Sjögren's syndrome? A meta-analysis of randomised controlled trials.

BACKGROUND: Previously, data mining methodology was used to identify 71 patented prescriptions in Chinese patent databases, indicating that Yin-nourishing therapy (YNT) may be an adjunct medication to hydroxychloroquine in the treatment of primary Sjögren's syndrome (pSS). The purpose of this study was to investigate effects of the addition of YNT, which includes tonifying liver and kidney therapy (TLKT) and replenishing Qi and nourishing Yin therapy (RQNYT), in the treatment of pSS. METHODS: Fourteen databases (including Chinese, English, Japanese, Korean and Latin databases) were searched to identify randomised controlled trials (RCTs) of YNT plus hydroxychloroquine (YNTPH) versus hydroxychloroquine alone in patients with pSS. Relevant publications up to June 2021 were selected. A meta-analysis and trial sequential analysis (TSA) were performed using Review Manager 5.3, Stata 14.0 and TSA 0.9 software. The quality of identified studies was assessed based on the Cochrane risk of bias tool and GRADE (grading of recommendations, assessment, development and evaluation) criteria. RESULTS: We included five RCTs with a total of 345 participants. Pooled results indicated significant differences in short-term outcomes, which were assessed via European League Against Rheumatism (EULAR) Sjögren's Syndrome Patient Reported Index (ESSPRI), EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI), tear production, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and immunoglobulin G (IgG) results when YNTPH was compared with hydroxychloroquine use alone (p < 0.05). No significant difference in salivary flow rate was reported. The most common side effect reported for both groups was gastrointestinal reaction. Sensitivity analyses suggested that heterogeneity might be ascribed to clinical methodology. Subgroup analyses revealed heterogeneities regarding salivary flow rate were eliminated. TLKT appeared to be better than RQNYT for improving salivary flow rate. TSA only supported changes in ESSPRI, ESSDAI and ESR values. For all studies, the quality of evidence was low. CONCLUSION: YNTPH may be an effective complementary therapy. Current evidence, however, is insufficient for determining whether YNTPH is more effective than hydroxychloroquine alone. Well-designed RCTs are needed to determine the role of YNT in pSS treatment.

Enhancement of Swimming Endurance by Herbal Supplement M3P.

OBJECTIVE: To investigate the effect of M3P (containing Deer antler, Cordyceps sinensis, Rhodiola rosea, and Panax ginseng); an herbal remedy with the function of tonifying Kidney (Shen) and invigorating Spleen (Pi), replenishing qi and nourishing blood; on fatigue alleviation, endurance capacity and toxicity. METHODS: Swimming with weight-loading of 24 male ICR mice was used to evaluate the endurance capacity, and fatigue-related plasma biomarkers were determined. Mice were randomly assigned to control or M3P treatment groups with 6 mice for each group and were orally administered with M3P everyday for 8 weeks at doses 0, 10, 33 or 100 mg/kg. Swimming time to exhaustion was measured in a specialized water tank. Lliver and kidney functions, body weight, and hematological profile were determined to evaluate the safety and toxicity after long-term M3P administration. RESULTS: M3P supplementation 100 mg/kg significantly increased swimming endurance time up to approximate 2.4 folds of controls (P<0.05). The plasma concentrations of cortisol and hepatic glycogen content were significantly increased in mice received M3P (P<0.05, P<0.01 respectively). The lactic acid level and blood glucose were not changed after M3P treatment (P>0.05). The liver and kidney functions muscle damage biomarker creatine, body weight, and hemograms were not altered in M3P supplementation (P>0.05). CONCLUSION: M3P supplementation may improve swimming endurance accompanied by increasing hepatic glycogen content and serum cortisol level without major toxicity.

[Xianfang Huoming Decoction improves sperm quality in asthenospermia mice: An investigation based on the detoxification and sperm-nourishing method].

OBJECTIVE: To investigate the mechanism of Xianfang Huoming Decoction (XHD) improving sperm motility in mice with asthenospermia (AS). METHODS: Thirty normal BALB/c mice were randomly divided into six groups, blank control, AS model control, low-dose XHD, medium-dose XHD, high-dose XHD and levocarnitine + vitamin E (LC+VE). The AS model was established in the latter five groups by injection of methotrexate at 0.5 mg/kg once a week, and the mice in the blank control group were injected with the same volume of normal saline, all for 8 weeks. From the ninth week, the animals in the blank control and AS model control groups were treated with PBS at 0.1 ml/d, those in the low-, medium- and high-dose XHD groups with XHD at 7.13, 14,2 and 28.52 g/kg/ d respectively, and those in the LC+VE group with LC+VE (30:1) at 0.55 g/kg/d, all for 4 weeks. Then, the bilateral epididymides were harvested from all the mice for preparation of a sperm suspension and observation of the total numbers of sperm and motile sperm. The testis tissues were obtained for to determination of the expressions of Nrf-2- and HO-1-related mRNA and proteins by fluorescence staining, RT-PCR and Western blot. RESULTS: Compared with the AS model controls, the mice treated with low-, medium- and high-dose XHD showed dramatically increased sperm concentration (ï¼»22.36 ± 16.02ï¼½ vs ï¼»39.04 ± 4.50ï¼½, ï¼»40.76 ± 6.57ï¼½ and ï¼»41.04 ± 8.39ï¼½ ×106/ml, P < 0.01) and motility (ï¼»22.89 ± 14.96ï¼½% vs ï¼»47.98 ± 4.74ï¼½%, ï¼»48.53 ± 6.03ï¼½% and ï¼»49.31 ± 6.24ï¼½%, P< 0.01), decreased level of reactive oxygen species (ROS) (ï¼»16.82 ± 14.96ï¼½% vs ï¼»12.08 ± 3.26ï¼½%, ï¼»10.77 ± 2.21ï¼½% and ï¼»9.56 ± 2.08ï¼½%, P< 0.01), and up-regulated expressions of Nrf-2- and HO-1-related mRNA and proteins in the testis tissue (P < 0.05 or P < 0.01). CONCLUSION: Xianfang Huoming Decoction inhibits the development of oxidative stress by up-regulating the expressions of Nrf-2- and HO-1-related mRNA and proteins in the testis tissue, which has provided theoretical evidence for its clinical application in the treatment of asthenospermia.

Impact of Policies in Nutrition and Physical Activity on Diabetes and Its Risk Factors in the 28 Member States of the European Union.

Since healthy eating and physically active lifestyles can reduce diabetes mellitus (DM) risk, these are often addressed by population-based interventions aiming to prevent DM. Our study examined the impact of nutritional and physical activity policies, national diabetes plans and national diabetes registers contribute to lower prevalence of DM in individuals in the member states of the European Union (EU), taking into account the demographic and socioeconomic status as well as lifestyle choices. Datasets on policy actions, plans and registers were retrieved from the World Cancer Research Fund International's NOURISHING and MOVING policy databases and the European Coalition for Diabetes report. Individual-based data on DM, socioeconomic status and healthy behavior indicators were obtained via the European Health Interview Survey, 2014. Our results showed variation in types and numbers of implemented policies within the member states, additionally, the higher number of these actions were not associated with lower DM prevalence. Only weak correlation between the prevalence of DM and preventive policies was found. Thus, undoubtedly policies have an impact on reducing the prevalence of DM, its increasing burden could not be reversed which underlines the need for applying a network of preventive policies.

Achieving Food System Transformation: Insights From A Retrospective Review of Nutrition Policy (In)Action in High-Income Countries.

BACKGROUND: Comprehensive nutrition policies are required urgently to help transform food systems to more equitably deliver healthy, sustainable diets. METHODS: Literature was searched systematically for nutrition policies of the then 34 Organisation for Economic Co-operation and Development (OECD) members as part of a scoping study. Recently, results were re-analysed, against the NOURISHING framework. RESULTS: Twenty-three nutrition policy documents were identified for 19 jurisdictions. Most policy actions focused on the behaviour change communication domain: all (100%) promoted consumption of 'healthy' choices. In the food environment domain, most policies included food labelling (84%), product reformulation (68%), providing healthy foods in public institutions (89%, mainly schools), and restricting food advertising (53%), largely through voluntary codes. Relatively few economic tools were being applied. There was very little focus on reducing consumption of 'unhealthy' food or drinks. Not all nutrition policy actions identified were covered by the NOURISHING framework. CONCLUSION: The NOURISHING framework could be expanded to more comprehensively encompass the health and sustainability dimensions of food systems, eg, by detailing optimum governance arrangements. As recently as seven years ago, half of the most developed economies globally did not have a publicly available nutrition policy. Existing policies were dominated by conventional nutrition education approaches, while policy actions targeting food environments, and regulatory and legislative reforms, were rare. This is consistent with a neo-liberal approach centring individual responsibility. No examples of the multi-strategy, inter-sectoral, coordinated, evidence-based policies required to drive systemic transformation were identified. Therefore, it is not surprising that rates of obesity and diet-related conditions have continued to rise in these jurisdictions, nor that governments are currently off-track to deliver the systemic transformation required to meet relevant global health and sustainable development goals.

Effectiveness of nourishing Yin and tonifying Yang sequential therapy in combination with Climen on diminished ovarian reserve: a retrospective study.

OBJECTIVE: To evaluate the clinical efficacy of nourishing Yin and tonifying Yang sequential therapy (NYTYST) in combination with the Western Medicine Climen in treating diminished ovarian reserve (DOR). METHODS: From September 2014 to September 2016, 46 patients with DOR who received NYTYST and Climen (treatment group) and 51 patients who received Climen only (control group) at the Jiangsu Provincial Traditional Chinese Medicine Hospital (Nanjing, China) were retrospectively reviewed. Before and at 3 months after treatment, serum levels of follicle-stimulating hormone (FSH), FSH/luteinizing hormone (LH), estradiol (E2), and anti-Mullerian hormone (AMH), the antral follicle count (AFC), stromal peak systolic velocity (PSV), symptom scores, and the clinical effectiveness rate were measured and compared between the two groups. RESULTS: After treatment, serum levels of FSH, FSH/LH and E2, and symptom scores were significantly decreased compared with before treatment (all P < 0.05) in the two groups. AMH levels, AFC, and PSV were significantly increased after treatment compared with before treatment in both groups (all P < 0.05). Serum levels of FSH, FSH/LH, and E2 after treatment were significantly lower in the treatment group than in the control group (all P < 0.05). However, AMH levels and the AFC were significantly higher after treatment in the treatment group than in the control group (both P < 0.05). The clinical effectiveness rate was significantly higher in the treatment group than in the control group (87% vs 68.6%, P < 0.05). CONCLUSION: NYTYST combined with Climen may be more effective in treating DOR than Climen alone.

Synergistic nourishing 'Yin' effect of iridoid and phenylpropanoid glycosides from Radix Scrophulariae in vivo and in vitro.

ETHNOPHARMACOLOGICAL RELEVANCE: Radix Scrophulariae (RS), is a renowned traditional Chinese medicine used as nourishing 'Yin'. The iridoid glycosides (IG) and phenylpropanoid glycosides (PG) are main chemical constituents in RS. However, there had been no pharmacological experiment studies of synergy between IG and PG. Due to the constituents interactions, exploring their synergy profile is of great important for explaining the essence of nourishing 'Yin' efficacy of RS. AIM OF STUDY: The present study was undertaken to evaluate synergistic nourishing 'Yin' effect of IG and PG from RS in vivo and in vitro through their immunoregulation and antioxidant activities. MATERIALS AND METHODS: In this study, IG and PG fractions in RS were isolated and identified by High Performance Liquid Chromatography coupled with tandem quadrupole time-of-flight Mass Spectrometry (HPLC-Q-TOF-MS). The synergistic nourishing 'Yin' effect of two fractions were investigated in vivo and in vitro with thyroxine-induced 'Yin' deficiency (YD) mice model and primary splenic lymphocyte, respectively. The exterior syndrome signs and serologic and cellular biomarkers changes were detected. Then, the synergistic coefficient (SC) of IG and PG on every pharmacodynamics index were calculated by Webb method. RESULTS: Compared with model and mono-therapy group (IG or PG group), IG combined with PG group significantly ameliorated YD by exerting immunoregulation and antioxidant effects. Based on the SC, IG and PG possessed a synergistic effect on heart rate, average speed, upright times, spleen index, LPO, SOD, IL-6, Na+-K+-ATP enzyme in vivo, and cAMP/cGMP, IFN-γ/IL-10, and MDA in vitro with SC > 1. CONCLUSIONS: The nourishing 'Yin' benefits were clearly produced when IG and PG were used in combination, which provided the scientific evidence of multiple-components and multiple-approach synergistic effect of Chinese traditional herbal medicine to control and management of diseases.
