Shen-Shuai-II-Recipe inhibits tubular inflammation by PPARα-mediated fatty acid oxidation to attenuate fibroblast activation in fibrotic kidneys.

BACKGROUND: Shen Shuai Ⅱ Recipe (SSR) is clinically used to treat chronic kidney diseases (CKDs) with remarkable efficacy and safety. In earlier research, we found the anti-inflammatory, antioxidant, and mitochondrial protective properties of SSR in hypoxic kidney injury model, which is closely related to its renal protection. Further work is needed to understand the underlying molecular mechanisms. PURPOSE: Further investigation of the mechanisms of action of SSR against renal interstitial fibrosis (RIF) building on previous research leads. METHODS: Rats receiving CKD model surgery were given with Fenofibrate or SSR once a day for eight weeks. In vitro, the NRK-52E cells were treated with SSR in the presence or absence of 10 µM Sc75741, 0.5 µM PMA, or 1 µM fenofibrate under 1% O2. The effects of SSR on NF-κB/NLRP3 inflammatory cascade, secretion of pro-inflammatory cytokines, fatty acid oxidation (FAO), and renal tubular injury were determined by immunoblotting, luminex liquid suspension chip assay, transmission electron microscopy, and Oil red O staining. Next, we delivered PPARα-interfering sequences to kidney tissue and NRK-52E cells by adeno-associated virus (AAV) injection and siRNA transfection methods. Finally, we evaluated the effect of renal tubular cells on fibroblast activation by co-culture method. RESULTS: SSR attenuated the release of IL-18, VEGF, and MCP1 cytokines, inhibited the activation of NF-κB/NLRP3 cascade, increased the PPARα, CPT-1α, CPT-2, ACADL, and MCAD protein expression, and improved the lipid accumulation. Further studies have demonstrated that one of the ways in which SSR suppresses the inflammatory response to protect renal tubular cells is through the restoration of PPARα-mediated FAO. In addition, by means of co-culture ways, the results demonstrated that SSR attenuated secretion of inflammatory mediators in NRK-52E cells by PPARα/NF-κB/NLRP3 pathway, thereby inhibiting renal fibroblast activation. CONCLUSION: SSR inhibits RIF by suppressing inflammatory response of hypoxia-exposed RTECs through PPARα-mediated FAO.

The Analysis of Serum Klotho Protein Level and Related Gene Polymorphism in Osteoporotic Fracture of Elderly Patients with Osteoporosis.

Objective: Klotho protein level are reported to play important roles in the osteoporosis. To investigate the correlation between serum Klotho protein level and related gene (Klotho G395-A gene) polymorphism and osteoporotic fracture in elderly patients with osteoporosis. Methods: A total of 62 elderly patients with osteoporosis admitted to the Department of Orthopedics of our hospital from January 2021 to June 2022 were included in the study group. Another 62 elderly patients without osteoporosis who underwent a physical examination at the same time were selected as the control group. Patients in the study group were divided into group A (n = 23, osteoporotic fracture) and group B (n = 39, osteoporotic fracture) according to the occurrence of osteoporotic fracture. Serum Klotho protein level was detected in all patients, and its related gene (Klotho G395-A gene) polymorphism was analyzed. After fasting in the morning (fasting for more than 8 hours), 3-5 ml venous blood was collected and immediately placed in a centrifuge tube. Serum was separated and serum Klotho protein level was measured by enzyme-linked immunosorbent assay kit. Polymorphism typing was performed by Taqman allele-specific hybridization analysis. At the same time, general information (gender, age, body mass index, systolic blood pressure, diastolic blood pressure, glycated glucose protein, low-density lipoprotein cholesterol, bone mineral density) was collected. The differences in general data, serum Klotho protein level and Klotho G395-A gene polymorphism between the study group and the control group were analyzed. Spearman analysis was used to analyze the correlation between general data, serum Klotho protein level and Klotho G395-A gene and osteoporotic fracture. Logistic analysis was used to analyze the independent risk factors of osteoporotic fracture. Results: There was no significant difference of the sex, systolic blood pressure (SBP), diastolic blood pressure (DBP), Klotho G395-A genotype GG and alleles A and G between the study group and the control group. There was significant difference of body mass index (BMI), glycated glucose protein, low-density lipoprotein cholesterol (LDL-C), bone mineral density, serum Klotho protein level and Klotho G395-A genotype AA and AG were between the study group and the control group. Gender, age, glycated glucose protein and Klotho G395-A genotype AA were positively correlated with osteoporotic fracture (P < .05), while bone mineral density was negatively correlated with osteoporotic fracture (P < .05). There was no correlationship between the serum Klotho protein level and the incidence of osteoporotic fracture (P > .05). Logistic analysis showed that age, bone mineral density and Klotho G395-A genotype AA were independent risk factors for osteoporotic fracture. Conclusion: The level of serum Klotho protein and related gene polymorphisms are both related to osteoporotic fracture in elderly patients with osteoporosis. It is significant to reduce the incidence of osteoporotic fractures. In future, more experiments are needed to explore the underlying mechanism.

EPs® 7630 Stimulates Tissue Repair Mechanisms and Modifies Tight Junction Protein Expression in Human Airway Epithelial Cells.

Airway epithelium repair after infection consists of wound repair, re-synthesis of the extracellular matrix (ECM), and tight junction proteins. In humans, EPs® 7630 obtained from Pelargonium sidoides roots reduces the severity and duration of acute respiratory tract infections. The effect of EPs® 7630 on tissue repair of rhinovirus-16 (RV-16) infected and control human airway epithelial cells was assessed for: (i) epithelial cell proliferation by manual cell counts, (ii) epithelial wound repair by "scratch assay", (iii) ECM composition by Western-blotting and cell-based ELISA, and (iv) epithelial tight junction proteins by Western-blotting. EPs® 7630 stimulated cell proliferation through cAMP, CREB, and p38 MAPK. EPs® 7630 significantly improved wound repair. Pro-inflammatory collagen type-I expression was reduced by EPs® 7630, while fibronectin was increased. Virus-binding tight junction proteins desmoglein2, desmocollin2, ZO-1, claudin1, and claudin4 were downregulated by EPs® 7630. The RV16-induced shift of the ECM towards the pro-inflammatory type was prevented by EPs® 7630. Most of the effects of EPs® 7630 on tissue repair and regeneration were sensitive to inhibition of cAMP-induced signaling. The data suggest that EPs® 7630-dependent modification of epithelial cell metabolism and function might underlie the faster recovery time from viral infections, as reported by others in clinical studies.

The effects and mechanisms of acupuncture for post-stroke cognitive impairment: progress and prospects.

Stroke is one of the important causes of both disability and death worldwide, which is very common in older adults. Post-stroke cognitive impairment (PSCI) is a common secondary damage of stroke, which is the main cause of long-term disability and decreased quality of life in stroke patients, which brings a heavy burden to society and families. Acupuncture, as one of the oldest and widely used worldwide techniques in Chinese medicine, is recommended by the World Health Organization (WHO) as an alternative and complementary strategy for improving stroke care. This review comprehensively summarizes literature from the last 25 years, showing that acupuncture can exert strong beneficial effect on PSCI. The mechanisms of acupuncture on PSCI involves anti-neuronal apoptosis, promoting synaptic plasticity, alleviating central and peripheral inflammatory reactions, and regulating brain energy metabolism disorders (including improving cerebral blood flow, glucose utilization and mitochondrial structure and function, etc.), etc. The effects and mechanisms of acupuncture on PSCI reviewed in this study provides scientific and reliable evidence for acupuncture application for PSCI.

Visualization of Traditional Chinese Medicine Formulas: Development and Usability Study.

BACKGROUND: Traditional Chinese medicine (TCM) formulas are combinations of Chinese herbal medicines. Knowledge of classic medicine formulas is the basis of TCM diagnosis and treatment and is the core of TCM inheritance. The large number and flexibility of medicine formulas make memorization difficult, and understanding their composition rules is even more difficult. The multifaceted and multidimensional properties of herbal medicines are important for understanding the formula; however, these are usually separated from the formula information. Furthermore, these data are presented as text and cannot be analyzed jointly and interactively. OBJECTIVE: We aimed to devise a visualization method for TCM formulas that shows the composition of medicine formulas and the multidimensional properties of herbal medicines involved and supports the comparison of medicine formulas. METHODS: A TCM formula visualization method with multiple linked views is proposed and implemented as a web-based tool after close collaboration between visualization and TCM experts. The composition of medicine formulas is visualized in a formula view with a similarity-based layout supporting the comparison of compositing herbs; a shared herb view complements the formula view by showing all overlaps of pair-wise formulas; and a dimensionality-reduction plot of herbs enables the visualization of multidimensional herb properties. The usefulness of the tool was evaluated through a usability study with TCM experts. RESULTS: Our method was applied to 2 typical categories of medicine formulas, namely tonic formulas and heat-clearing formulas, which contain 20 and 26 formulas composed of 58 and 73 herbal medicines, respectively. Each herbal medicine has a 23-dimensional characterizing attribute. In the usability study, TCM experts explored the 2 data sets with our web-based tool and quickly gained insight into formulas and herbs of interest, as well as the overall features of the formula groups that are difficult to identify with the traditional text-based method. Moreover, feedback from the experts indicated the usefulness of the proposed method. CONCLUSIONS: Our TCM formula visualization method is able to visualize and compare complex medicine formulas and the multidimensional attributes of herbal medicines using a web-based tool. TCM experts gained insights into 2 typical medicine formula categories using our method. Overall, the new method is a promising first step toward new TCM formula education and analysis methodologies.

Identification and localization of morphological feature-specific metabolites in Reynoutria multiflora roots.

Reynoutria multiflora roots are a classical herbal medicine with unique nourishing therapeutic effects. Anomalous vascular bundle (AVB) forming "cloudy brocade patterns" is a typical morphological feature of R. multiflora roots and has been empirically linked to its quality classification. However, scientific evidence, especially for AVB-specific specialised metabolites, has not been comprehensively revealed thus far. Herein, desorption electrospray ionization-mass spectrometry imaging (DESI-MSI) analysis was applied to carry out an in situ analysis of specialised metabolites distributed specifically at the AVB and cork of R. multiflora roots. To enlarge the scope of compounds by DESI detection, various solvent systems including acetone, acetonitrile, methanol, and water were used to assist in the discoveries of 40 specialised metabolites with determined localization. A series of bioactive constituents including stilbenes, flavonoids, anthraquinones, alkaloids, and naphthalenes were found specifically around the brocade patterns. Notably, phospholipids were detected from R. multiflora roots by in situ analysis for the first time and were found mainly in the phloem of AVB (PAB). This is the first study to use gradient solvent systems in DESI-MSI analysis to locate the specialised metabolites distribution. The discovery of feature-specific compounds will bridge the empirical identification to precision quality control of R. multiflora roots.

Diallyl Trisulfide attenuates alcohol-induced hepatocyte pyroptosis via elevation of hydrogen sulfide.

Garlic is a popular culinary herb for the prevention and treatment of alcoholic liver disease (ALD). Diallyl Trisulfide (DATS) is the major organosulfur compound of garlic. Latest studies indicated that the hepatocyte pyroptosis serves a primary role in the pathogenesis of ALD. The present study aims to assess the inhibitory effect of DATS on alcohol-induced hepatocyte pyroptosis, and to elucidate the potential mechanism by using the hepatocyte cell line HL-7702. Our study found that DATS inhibited alcohol-induced pyroptosis by decreasing gasdermin D (GSDMD) activation. Results illuminated that DATS inhibited alcohol-induced (NOD)-like receptor containing pyrin domain 3 (NLRP3) inflammasome activation by reducing intracellular reactive oxygen species (ROS) accumulation. Furthermore, DATS upregulated hydrogen sulfide (H2S) to resist ROS overproduction. The present study demonstrated that DATS mitigated alcohol-induced hepatocyte pyroptosis by increasing the intracellular level of H2S.

Enhanced Inhibitory Effect of DC-CIK Cells on Lung Adenocarcinoma via Anti-Tim-3 Antibody and Antiprogrammed Cell Death-1 Antibody and Possible Mechanism.

Objective: To investigate the effect and mechanism of blocking the signaling pathways of the T-cell immunoglobulin and mucin domain-containing protein 3 (Tim-3) and programmed death protein 1 (PD-1) in dendritic cell-cytokine induced killer (DC-CIK) cells on human lung adenocarcinoma A549 cells. Methods: Peripheral blood mononuclear cells (PBMCs) were isolated and induced into mature DC-CIK cells by cytokines in vitro. After blocking the Tim-3 and PD-1 signaling transduction pathways with anti-Tim-3 and anti-PD-1 antibodies, DC-CIK cells were coincubated with A549 cells. The killing effect of DC-CIK cells against A549 cells was measured by a CCK-8 assay. The impact of DC-CIK cells on the invasion and migration ability of A549 cells was detected by the Transwell test. The apoptosis rate of DC-CIK cells and the ratio of CD4+, CD8+, and DC-CIK cell subsets were determined by flow cytometry. The cell proliferation of DC-CIK was detected by the CCK-8 assay. Results: The antibodies of anti-Tim-3 antibody and anti-PD-1 could block Tim-3+ and PD-1+ DC-CIK cells and could significantly increase the killing effect of DC-CIK cells on A549 cells. The number of A549 cells under the microporous membrane of the Transwell chamber was reduced considerably in invasion and migration tests. Anti-Tim-3 and anti-PD-1 antibodies significantly reduced apoptosis of DC-CIK cells. No significant differences were observed in the ratios of CD4+ and CD8+ DC-CIK cell subsets or the proliferation capacity of DC-CIK cells in each group. Conclusion: Blocking the Tim-3 and PD-1 signaling pathways of DC-CIK cells with antibodies can enhance the killing ability of DC-CIK cells in A549 cells and significantly suppress the invasion and migration ability of A549 cells. The potential mechanism may be related to reduced apoptosis of DC-CIK cells.

Acupuncture in treating obesity combined with type 2 diabetes mellitus: A systematic review and meta-analysis of randomized controlled clinical trials.

BACKGROUND: and purpose: Most type 2 diabetes mellitus (T2DM) patients are accompanied by overweight or obesity, and it is difficult to concurrently solve these two issues with conventional treatment regimens without experiencing adverse effects. While clinical practice demonstrates that acupuncture is beneficial in treating obesity combined with T2DM, there is a lack of evidence-based medicine to support this claim. The study aims to systematically evaluate the efficacy and safety of acupuncture in treating obesity combined with T2DM. METHODS: By searching eight electronic databases, we collected randomized controlled trials on acupuncture in treating obesity combined with T2DM. Two reviewers independently screened the literature, extracted the data, and assessed the risk of bias in the included studies. Meta-analysis was then performed using RevMan 5.4 software. RESULTS: A total of 13 randomized controlled trials (RCTs) involving 993 patients were eventually included. Meta-analysis results demonstrated the effective rate of clinical symptoms: [RR = 1.19, 95% CI: 1.11, 1.28, P < 0.00001]; body mass index: [MD = -2.11, 95% CI: -2.56, -1.66, P < 0.00001]; fasting plasma glucose: [MD = -1.09, 95% CI: -1.60, -0.59, P < 0.00001]; haemoglobin A1c: [MD = -0.58, 95% CI: -0.95, -0.20, P = 0.002]; triglyceride: [MD = -0.29, 95% CI: -0.46, -0.11, P = 0.001]; waist circumference: [MD = -5.36, 95% CI: -8.68, -2.05, P = 0.002]; body fat rate: [MD = -3.59, 95% CI: -4.28, -2.90, P < 0.00001]. CONCLUSION: Current evidence suggests that acupuncture has advantages in treating obesity combined with T2DM. However, due to low-quality evidence of included research, additional large-sample and high-quality research are required to validate the findings of this study.

Reliability of Evidence to Guide Decision-Making in the Use of Acupuncture for Postpartum Depression.

Background: There is conflicting evidence on the effectiveness of acupuncture in the treatment of postpartum depression (PPD). This study aimed to assess previous systematic reviews/meta-analyses (SRs/MAs) on the effectiveness of acupuncture to treat PPD. Method: SRs/MAs regarding the use of acupuncture for PPD were identified from the establishment of digital databases to November 2021. The Assessing the Methodological Quality of Systematic Reviews 2 (AMSTAR-2) was applied to evaluate the methodological quality of included SRs/MAs. The Grades of Recommendations, Assessment, Development and Evaluation (GRADE) was utilized to evaluate the evidence quality for outcomes of interest. Results: Six studies that conducted quantitative syntheses were included. According to AMSTAR-2, the methodological quality of these SRs/MAs was critically low owing to limitations of items 2, 4, and 7. According to GRADE, no study included high-quality evidence and most studies included low-quality evidence. Conclusions: Acupuncture m be beneficial for PPD, however, due to limitations of current evidence and inconsistent findings, further studies are needed to provide stronger evidence to draw definitive conclusions.

Phototherapy for Cognitive Function in Patients With Dementia: A Systematic Review and Meta-Analysis.

Background: Dementia is a major health burden worldwide. As numerous pharmacological trials for dementia have failed, emerging phototherapy studies have evaluated the efficacy of alternative therapies for cognition. Objective: The objective of this study was to evaluate the association between phototherapy and changes in cognitive deficits in patients with dementia. Methods: PubMed, Embase, Web of Science, PsycINFO, CINAHL, and Cochrane Central Register of Controlled Trials were searched from inception to 27 March 2022. Inclusion criteria were controlled clinical trials of phototherapy interventions reporting pre-post changes in global cognitive function and subdomains in patients with dementia. Data were extracted by two independent reviewers and pooled in random-effects models. Subgroup and meta-regression analyses were conducted to investigate the sources of heterogeneity. Results: Our analyses included 13 studies enrolling a total of 608 participants. Phototherapy showed significant associations with improvements of global cognitive function (standardized mean difference [SMD], 0.63; 95% confidence interval [CI], 0.33-0.94; P < 0.001) and subdomains, especially with respect to attention, executive function, and working memory. Near-infrared (NIR) light-emitting diodes (LEDs) photobiomodulation (SMD, 0.91; 95% CI, 0.46-1.36; P < 0.001) and lasers (SMD, 0.99; 95% CI, 0.56-1.43; P < 0.001) showed more significant associations with improved cognitive functions when compared with normal visible light. In addition, the effect sizes of short-term effects (SMD, 0.63; 95% CI, 0.33-0.94; P < 0.001) were larger than effects assessed in long-term follow-up (SMD, 0.49; 95% CI, -0.24-1.21; P = 0.189). Conclusion: In this meta-analysis, phototherapy interventions were associated with cognitive improvement in patients with dementia. NIR LEDs and lasers had advantages over normal visible light. Domain-specific effects were indicated for attention, executive function, and working memory. Short-term improvement after phototherapy was supported, while evidence for long-term benefits was lacking. Stronger evidence for individualized parameters, such as optimal dosing, is needed in the future.

Comparison of Efficacy of Acupuncture-Related Therapy in the Treatment of Rheumatoid Arthritis: A Network Meta-Analysis of Randomized Controlled Trials.

Background: The refractory, repetitive, and disabling characteristic of rheumatoid arthritis (RA) has seriously influenced the patients' quality of life, and makes it a major public health problem. As a classic complementary and alternative therapy, acupuncture is usually applied for RA combined with disease-modifying anti-rheumatic drugs (DMARDs). However, there are various types of acupuncture, and the curative effects are different in different acupuncture therapies. In this study, we evaluated the clinical efficacy of different acupuncture therapies combined with DMARDs in the treatment of RA. Methods: The randomized controlled trials (RCTs) of acupuncture combined with DMARDs in the treatment of RA were searched in both English and Chinese database of PubMed, Cochrane Library, EMBASE, Web of Science, CNKI, VIP database, Wanfang, and SinoMED, up to October 2021. Literature screening, data extraction, and evaluation of the risk of bias were carried out independently by two researchers, and the data were analyzed by Stata14.2 and GeMTC 0.14.3 software. Results: A total of 32 RCTs were included, including 2,115 RA patients. The results of network meta-analysis were as follows: in terms of improving DAS28 score, Electro-acupuncture + DMARDs has the best efficacy. In terms of improving VAS score, Fire Needle + DMARDs showed the best efficacy. In terms of improving morning stiffness time, acupuncture-related therapies combined with DMARDs were not better than DMARDs alone in improving morning stiffness time in RA patients. In terms of reducing CRP and ESR, Fire Needle + DMARDs showed the best efficacy. In terms of reducing RF, Moxibustion + DMARDs has the best efficacy. Conclusions: The comprehensive comparison of the outcome indicators in 8 different treatments indicates that electro-acupuncture combined with DMARDs is the best combined therapy in improving DAS28 score, while in terms of improving pain and serological markers, fire needle combined with DMARDs and moxibustion combined with DMARDs were the best combined therapies. However, it is impossible to find out which is better between fire needle and moxibustion due to the limited studies. Clinically, appropriate treatment should be selected according to the actual situation. Systematic Review Registration: https://www.crd.york.ac.uk/prospero/#recordDetails, CRD42021278233.

Efficacy and Safety of Acupuncture in the Treatment of Poststroke Insomnia: A Systematic Review and Meta-Analysis of Twenty-Six Randomized Controlled Trials.

Objective: To evaluate the efficacy and safety of acupuncture in the treatment of poststroke insomnia. Methods: PubMed, the Cochrane Library, Embase, Web of Science, China Biology Medicine (CBM), CNKI, VIP, and Wanfang databases were searched by computer from their inception to April 29, 2021, for collecting all randomized controlled trials of acupuncture in the treatment of poststroke insomnia. After two reviewers independently screened the literature, extracted the data, and evaluated the risk of bias in the included studies, the data were analyzed by RevMan 5.3 and STATA 16.0. The quality of outcomes was evaluated by the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Results: A total of 26 studies with 1874 cases were included, which had 942 cases in the treatment group and 932 cases in the control group. Meta-analysis results showed that, compared with oral medications alone, acupuncture alone or acupuncture combined with oral medications could improve the clinical effective rate and the sleep quality of patients, and the combined effects were RR = 1.21; 95% CI: 1.15, 1.27; P < 0.00001 and MD = 3.41; 95% CI: 2.40, 4.41; P < 0.00001, respectively. As for adverse reactions, the incidence of acupuncture alone or acupuncture combined with oral drugs was lower than that of oral drugs alone, which was safer and the combined effect was RR = 0.21; 95% CI: 0.09, 0.48; P=0.0002. Sensitivity analysis showed that the results were stable. We evaluated the quality of evidence with the GRADE system; the clinical effective rate was rated as "LOW," the evidence grade of PSQI score was "LOW," and the evidence grade of adverse reactions was "Very LOW." Conclusion: Acupuncture alone or acupuncture combined with oral drugs is more effective and safer than oral drugs alone in the treatment of poststroke insomnia, which is suitable to promote in clinical practice.

Evaluation of texture, retrogradation enthalpy, water mobility, and anti-staling effects of enzymes and hydrocolloids in potato steamed bread.

The functionalities of hydrocolloids and enzymes in texture, retrogradation enthalpy, water mobility and distribution, and anti-staling effects of potato steamed bread stored for 0, 24, and 48 h at 25 °C were investigated. Four kinds of hydrocolloids, including carrageenan, xanthan gum, arabic gum, sodium alginate, and one kind of enzyme (xylanase) showed little effects on the hardness reduction and springiness retention of potato steamed bread during storage, while the presence of α-amylase and lipase could slow down its staling rate. Potato steamed bread with combination of α-amylase (20 mg/kg) and lipase (40 mg/kg) exhibited the lowest hardness, with a significant reduction of 44.20%, besides improving the specific volume, L*, and overall acceptability in sensory evaluation. The addition of α-amylase and lipase could decrease the retrogradation enthalpy and bound water, and increase the mobility of mobile water. These findings shed efficient methods to retard staling of potato steamed bread.

BACKGROUND: The tic disorders are common neuropsychiatric disorders that affects the growth and development of children and adolescents. Chinese herbal medicine is commonly used for the treatment of tic disorders. However, there is no consensus on the difference in clinical efficacy compared with routine treatment. Therefore, we plan to perform a systematic review and meta-analysis to review the clinical efficacy of Chinese herbal medicine for tic disorders. METHODS: Cochrane Central Register of Controlled Trials, PubMed, EMBASE, Chinese National Knowledge Infrastructure, Chinese Bio-medical Database, and Wanfang database will be searched from their inception until March 31, 2021. The meta-analysis will be conducted with Review Manager 5.3 software to systematically review the clinical efficacy and safety of Chinese herbal medicine for tic disorders. The primary outcome will include the improvement rate (amount) of tic symptoms using related scales or methods, and the secondary outcome will include adverse events. RESULTS: This analysis will provide useful information about clinical efficacy and safety of Chinese herbal medicine for tic disorders. CONCLUSIONS: Our study will generate strong evidence of Chinese herbal medicine for patients with tic disorders and provide suggestions for clinical practice.

[Screening of plant growth-promoting rhizobacteria and its effect on seed germination of Polygonum multiflorum].

In this study, the rhizobacteria and actinomycetes of Polygonum multiflorum were screened for the strains with indole acetic acid(IAA)-producing capacity by Salkowski method, the siderophore-producing strains by Chrome Azurol S(CAS) assay, and the strains with inorganic phosphorus-solubilizing capacity by PKO inorganic phosphorus medium. The strains were identified by morphological identification, physiological and biochemical characteristics, and 16 S rDNA sequences. Furthermore, the effect of growth-promoting strains on the seed germination and development of P. multiflorum was tested. The results showed that among 196 strains, two strains F17 and F42 were found to be capable of producing IAA and siderophore and solubilizing inorganic phosphorus simulta-neously. For F17 and F42, the results are listed below: 38.65 and 33.64 mg·L~(-1) for IAA production, 0.85 and 0.49 for siderophore-producing capacities(A_s/A_r), and 1.35 and 1.70 for inorganic phosphorus-solubilizing capacities(D/d), respectively. Comprehensive analysis revealed that strains F17 and F42 were identified as Pseudochrobactrum asacharolyticum and Bacillus aryabhattai, respectively, and both could significantly promote the seed germination of P. multiflorum.

Prevalence of depressive disorders and treatment in China: a cross-sectional epidemiological study.

BACKGROUND: In China, depressive disorders have been estimated to be the second leading cause of years lived with disability. However, nationally representative epidemiological data for depressive disorders, in particular use of mental health services by adults with these disorders, are unavailable in China. The present study, part of the China Mental Health Survey, 2012-15, aims to describe the socioeconomic characteristics and the use of mental health services in people with depressive disorders in China. METHODS: The China Mental Health Survey was a cross-sectional epidemiological survey of mental disorders in a multistage clustered-area probability sample of adults of Chinese nationality (≥18 years) from 157 nationwide representative population-based disease surveillance points in 31 provinces across China. Trained investigators interviewed the participants with the Composite International Diagnostic Interview 3.0 to ascertain the presence of lifetime and 12-month depressive disorders according to DSM-IV criteria, including major depressive disorder, dysthymic disorder, and depressive disorder not otherwise specified. Participants with 12-month depressive disorders were asked whether they received any treatment for their emotional problems during the past 12 months and, if so, the specific types of treatment providers. The Sheehan Disability Scale (SDS) was used to assess impairments associated with 12-month depressive symptoms. Data-quality control procedures included logic check by computers, sequential recording check, and phone-call check by the quality controllers, and reinterview check by the psychiatrists. Data were weighted according to the age-sex-residence distribution data from China's 2010 census population survey to adjust for differential probabilities of selection and differential response, as well as to post-stratify the sample to match the population distribution. FINDINGS: 28 140 respondents (12 537 [44·6%] men and 15 603 [55·4%] women) completed the survey between July 22, 2013, and March 5, 2015. Ethnicity data (Han or non-Han) were collected for only a subsample. Prevalence of any depressive disorders was higher in women than men (lifetime prevalence odds ratio [OR] 1·44 [95% CI 1·20-1·72] and 12-month prevalence OR 1·41 [1·12-1·78]), in unemployed people than employed people (lifetime OR 2·38 [95% CI 1·68-3·38] and 12-month OR 2·80 [95% CI 1·88-4·18]), and in people who were separated, widowed, or divorced compared with those who were married or cohabiting (lifetime OR 1·87 [95% CI 1·39-2·51] and 12-month OR 1·85 [95% CI 1·40-2·46]). Overall, 574 (weighted % 75·9%) of 744 people with 12-month depressive disorders had role impairment of any SDS domain: 439 (83·6%) of 534 respondents with major depressive disorder, 207 (79·8%) of 254 respondents with dysthymic disorder, and 122 (59·9%) of 189 respondents with depressive disorder not otherwise specified. Only an estimated 84 (weighted % 9·5%) of 1007 participants with 12-month depressive disorders were treated in any treatment sector: 38 (3·6%) in speciality mental health, 20 (1·5%) in general medical, two (0·3%) in human services, and 21 (2·7%) in complementary and alternative medicine. Only 12 (0·5%) of 1007 participants with depressive disorders were treated adequately. INTERPRETATION: Depressive disorders in China were more prevalent in women than men, unemployed people than employed, and those who were separated, widowed, or divorced than people who were married or cohabiting. Most people with depressive disorders reported social impairment. Treatment rates were very low, and few people received adequate treatment. National programmes are needed to remove barriers to availability, accessibility, and acceptability of care for depression in China.

Light therapy improved depression-like behavior induced by chronic unpredictable mild stress in Mongolian gerbils.

Progress has been made in elucidating the mechanism by which light modulates depressive-like behaviors. However, almost all of these studies ignore an important issue, namely, that examining the effects of light therapy in nocturnal animals may be difficult because the influences of light on behavioral responses differ between nocturnal and diurnal animals. To date, few diurnal rodents have been utilized to establish animal models that closely mimic clinical depression. Herein, the chronic unpredictable mild stress model, which is the most representative, reliable, and effective rodent model of depression, was implemented in diurnal Mongolian gerbils for the first time. The gerbils were subjected to two hours of light therapy or fluoxetine treatment for 2 weeks. Our work revealed that Mongolian gerbils subjected to chronic unpredictable mild stress showed depression-like behaviors. Interestingly, we also found that light therapy improved anhedonic behavior more effectively than fluoxetine after two weeks of treatment. In summary, our study is the first to use diurnal Mongolian gerbils, which have the same circadian rhythm as humans, to establish an effective, economical, and practical animal model of depression and confirmed that light therapy could improve depression-like behavior more effectively than fluoxetine to some extent in diurnal Mongolian gerbils, which establishes a good foundation for clarifying the neural mechanism of light therapy for depression.

Hyperoside Attenuate Inflammation in HT22 Cells via Upregulating SIRT1 to Activities Wnt/ß-Catenin and Sonic Hedgehog Pathways.

Neuroinflammation plays important roles in the pathogenesis and progression of altered neurodevelopment, sensorineural hearing loss, and certain neurodegenerative diseases. Hyperoside (quercetin-3-O-ß-D-galactoside) is an active compound isolated from Hypericum plants. In this study, we investigate the protective effect of hyperoside on neuroinflammation and its possible molecular mechanism. Lipopolysaccharide (LPS) and hyperoside were used to treat HT22 cells. The cell viability was measured by MTT assay. The cell apoptosis rate was measured by flow cytometry assay. The mRNA expression levels of interleukin-1ß (IL-1ß), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-α (TNF-α) were determined by quantitative reverse transcription polymerase chain reaction. The levels of oxidative stress indices superoxide dismutase (SOD), reactive oxygen species (ROS), catalase (CAT), glutathione (GSH), and malondialdehyde (MDA) were measured by the kits. The expression of neurotrophic factor and the relationship among hyperoside, silent mating type information regulation 2 homolog-1 (SIRT1) and Wnt/ß-catenin, and sonic hedgehog was examined by western blotting. In the LPS-induced HT22 cells, hyperoside promotes cell survival; alleviates the level of IL-1ß, IL-6, IL-8, TNF-α, ROS, MDA, Bax, and caspase-3; and increases the expression of CAT, SOD, GSH, Bcl-2, BDNF, TrkB, and NGF. In addition, hyperoside upregulated the expression of SIRT1. Further mechanistic investigation showed that hyperoside alleviated LPS-induced inflammation, oxidative stress, and apoptosis by upregulating SIRT1 to activate Wnt/ß-catenin and sonic hedgehog pathways. Taken together, our data suggested that hyperoside acts as a protector in neuroinflammation.

[Preliminary study on memory function of Sorbus aucuparia suspension cell to biotic stress].

Plants have a memory function for the environmental stress they have suffered. When they are subjected to repeated environmental stress, they can quickly and better activate the response and adaptation mechanism to environmental stress, thus realizing long-term stable reproduction. However, most of the relevant studies are applied to crops and Arabidopsis thaliana rather than medicinal plants about the improvement of plant growth status and the effect on phytoalexin biosynthesis. In this study, yeast extract(YE) was used as an elicitor to simulate biotic stress, and the changes in biomass and the content of some secondary metabolites were measured by giving repeated stresses to Sorbus aucuparia suspension cell(SASC). The results showed that the accumulation levels of biomass and some secondary metabolites in SASC subjected to repeated stress are significantly increased at some time points compared with single stress. A phenomenon that SASC can memorize biotic stress is confirmed in this study and influences phytoalexin accumulation in SASC. Furthermore, the work laid the groundwork for research into the transgenerational stress memory mechanism of medicinal plant.
