Metabolic profile changes of kidney aging and protective effects of Polygonatum sibiricum polysaccharides on D-galactose-induced aging mice / 数字中医药（英文）

Objective@#To investigate the metabolic trajectory of kidney aging and the effects of Polygonatum sibiricum polysaccharides (PSP) against kidney aging in D-galactose (D-gal)-induced aging mice, based on ultra-performance liquid chromatography/Q-Exactive Orbitrap mass spectrometry (UPLC-Q-Exactive MS/MS). @*Methods@#A total of 36 C57 BL/6J mice were randomly allocated to six groups: control (CON), model (MOD), PSP low-dose (PSP-L), PSP medium-dose (PSP-M), PSP high-dose (PSP-H), and positive drug ascorbic acid (VC) groups. To create models of aging mice, D-gal was intraperitoneally administered to all other groups of mice except the CON group. After modeling, the appropriate Chinese medicine [PSP-L: 150 mg/(kg·d), PSP-M: 300 mg/(kg·d), PSP-H: 600 mg/(kg·d)] or positive drug [ascorbic acid, 300 mg/(kg·d)] was administered for intervention. Key markers of renal function in urine and serum of mice in each group, such as creatinine (Crea), urea nitrogen (BUN), and uric acid (UA) levels, as well as key indicators of oxidative stress in serum and kidney, including superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and glutathione peroxidase (GSH-Px) were determined to validate the successful establishment of kidney aging models and to estimate the effects of PSP. Hematoxylin and eosin (HE), periodic acid Schiff (PAS), and β-galactosidase staining were used to assess the renal pathological changes. The metabolic profiles of serum, kidney, and urine samples from CON, MOD, and PSP-H groups were analyzed by UPLC-Q-Exactive MS/MS, and pattern recognition methods were used to outline the metabolic trajectory of kidney aging and to identify the characteristic metabolites. @*Results@#Age-related alterations in renal histopathology and impaired renal function in mice were also associated with oxidative stress indicators. Following the injection of PSP [PSP-H: 600 mg/(kg·d)], the pathological indices associated with aging were adjusted to normal levels, renal function and oxidative stress were improved in aging mice, and renal pathological damage was markedly improved. Meanwhile, the potential biomarkers were identified by UPLC-Q-Exactive MS/MS analysis and were further analyzed to form related metabolic pathways, with P < 0.05 as a threshold. The results showed that purine, sphingolipid, glycerophospholipid, tryptophan, and riboflavin metabolisms were the main metabolic pathways associated with aging. After administration of PSP, these pathological indices returned to normal levels, and biomarkers related to the aging process, such as adenosine monophosphate (AMP), tryptophan, and 5-hydroxytryptophan, also demonstrated, to some degree, reverse regulation (promoting synthesis). @*Conclusion@#Metabolomics methods based on UPLC-Q-Exactive MS/MS and multivariate statistical analysis can be adopted to establish metabolic profiles in aging mice. PSP has been shown to protect against kidney aging by interfering with the purine, sphingolipid, glycerophospholipid, tryptophan, and riboflavin metabolisms in the kidney.

Objective:To observe the clinical efficacy of Wenjing Huayu Zhitong therapy in treating primary dysmenorrhea (PD) with cold coagulation and blood stasis, and to explore its immune mechanisms on PD. Method:The 108 PD patients with cold coagulation and blood stasis syndrome were collected and randomly divided into traditional Chinese medicine (TCM) group, ibuprofen group and placebo group according to the random number table method, with 36 cases in each group. All patients received corresponding medicines three days before menstruation. The patients in TCM group were treated with TCM and ibuprofen sustained release capsule simulator. The patients in ibuprofen group were treated with ibuprofen sustained-release capsule and TCM simulator. The patients in placebo group were treated with TCM simulator and ibuprofen sustained-release capsule simulator. Treatment lasted for 6 consecutive days for three menstrual cycles, and follow-up was conducted for three menstrual cycles after drug withdrawal. The visual analogue score (VAS), total time of abdominal pain and TCM symptom scores in each menstrual cycle were recorded. The levels of CD3+, CD4+, CD8+ and the ratio of CD4+/CD8+ in peripheral blood before and after treatment were detected by flow cytometry. Result:After treatment for three menstrual cycles, both the TCM group and ibuprofen group were better than placebo group in reducing VAS score and reducing total abdominal pain time (P<0.01). The long-term follow-up effect after drug withdrawal in TCM group was significantly better than that in ibuprofen group (P<0.01). The total effective rate was 91.43% (32/35) in TCM group, 66.67% (10/33) in ibuprofen groups, and 30.30% (10/33) in placebo group . The efficacy of the TCM group was better than that of the ibuprofen group (χ2=-2.971, P<0.01), and the efficacy of the ibuprofen group was better than that of the placebo group (χ2=-2.371, P<0.05). After treatment, the levels of CD3+, CD4+ and CD4+/CD8+ in TCM group were significantly increased and the levels of CD8+ were decreased significantly as compared with those before treatment (P<0.01). After treatment, the levels of CD4+ and CD4+/CD8+ in TCM group were higher (P<0.05，P<0.01)，while the levels of CD8+ were significantly lower than those in ibuprofen group and placebo group (P<0.01). Conclusion:Wenjing Huayu Zhitong therapy can reduce the VAS score and accumulative time of abdominal pain, and improve the dysmenorrhea symptoms in patients with PD. Reversal of the T cell subsets disorder may be one of its mechanisms in treating PD with cold coagulation and blood stasis.

Retrospective analysis and discussion on 74 cases of adverse reactions of traditional Chinese medicine injection / 中国中药杂志

As a modern dosage form drug with rapid effect, traditional Chinese medicine (TCM) injection has been more and more used in clinical practice. Meanwhile the safety of TCM injection has attracted more and more attention. The retrospective analysis on 74 cases of adverse reaction of TCM injections collected from 2007 to 2016 in the Third Affiliated Hospital of Beijing University of Chinese Medicine showed that the proportion of men and women with adverse reactions was 0.54:1; the average age was 62.5 years old; 21 kinds of TCM injections were involved. Among them, the most reported were blood-regulating agents. The top four kinds of TCM injections with highest adverse drug reactions (ADRs) were Tanreqing injection, Danhong Injection, Shuxuening Injection and Xuesaitong for injection. The top three clinical manifestations of adverse reactions were lesions of skin and its appendages, damage of circulatory system and damage of nervous system. The potential causes of the adverse reactions of TCM injections were analyzed, and it was believed that individual difference, medicine, pharmaceutical excipients, solvent and TCM syndrome differentiation may be the main five causes for the adverse reactions of TCM injections. In order to reduce the adverse reactions of TCM injections, it is suggested that the clinical pharmacists should participate in the application management of TCM injections in the hospital; the production enterprises shall strengthen the whole life cycle management of the drugs; and at the same time, the drug control and administration authorities should improve the drug management methods constantly and encourage the development of TCM injections to the high quality level.

Evaluating the efficacy of Tui Na in treatment of childhood anorexia: a meta-analysis.

CONTEXT: Medical practitioners are now seeing more children younger than 15 y who are developing childhood anorexia. Hua Tuo chiropractic treatments are an ancient and practical massage therapy and are a type of Tui Na therapy, which has been used for curing childhood anorexia for thousands of years in China. Research literature suggests that chiropractic care produces outcomes at least comparable with alternative treatments. OBJECTIVE: The research team intended to perform a systematic review to identify and synthesize evidence on the efficacy of Tui Na for treatment of childhood anorexia. DESIGN: Systematic searches were conducted for studies evaluating Tui Na therapy in electronic databases MEDLINE, EMBASE, PsychINFO, the Cochrane Library, the Cumulative Index to Nursing and Allied Health Literature, the Midwives Information and Resource Service, the Health Management Information Consortium, the Health Management and Information Service, PubMed, the Chinese National Knowledge Infrastructure (CNKI), the Chinese Biomedical Literature Database (CBM), the Chinese Scientific Journal Database VIP, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), and the Chinese Clinical Trial Register-from inception to November 2011. The research team hand-searched reference lists and journals, extracted data from the papers, and assessed the quality of the research. PARTICIPANTS: Participants of the reviewed studies were infants and children younger than 15 y. RESULTS: Of the 109 papers identified, 3 papers reported on randomized, controlled trials (RCTs) involving 332 patients; 45 covered cohort or quasi-experimental studies; and 61 discussed nonintervention studies. Meta-analysis results from the 3 RCTs showed that Tui Na can improve the curative effect compared with oral medicine that is used for infants and young children with anorexia and can also increase a child's weight. CONCLUSIONS: The level of evidence reported was mixed, but given the available evidence, the research team concluded that Tui Na therapy was a viable intervention that could benefit infants and young children with anorexia. No serious adverse events were reported. Larger randomized, controlled trials are required to explore the effects of Tui Na therapy for treatment of childhood anorexia further.

Determination of six triterpene acid contents in effective fraction of Eriobotryae Folium by quantitative analysis of multi-components by single-marker / 中草药

Objective: To develop a quantitative analysis of multi-components by single-marker (QAMS) method for the simultaneous determination of six triterpene acid (euscaphic acid, tormentic acid, maslinic acid, corosolic acid, oleanolic acid, and ursolic acid) contents in the effective fraction of Eriobotryae Folium. Methods: Ursolic acid was used as the internal reference substance, and the relative correlation factors (RCF) of euscaphic acid, tormentic acid, maslinic acid, corosolic acid, and oleanolic acid were determined by HPLC-ELSD with good reproducibility. The contents of the five components were calculated according to the RCF, respectively. The contents of these six triterpene acids in 15 batches of effective fraction were determined by the external standard method. The rationality, feasibility, and repeatability of the QAMS method were verified by comparing the results obtained from the two different methods. Results: For the six triterpene acids, there was no significant difference between the quantitative results with the two different methods in the 15 batches. Conclusion: The method established in this research is accurate and feasible that it just needs to assay single-marker (ursolic acid) for the determination of six triterpene acids in the effective fraction of Eriobotryae Folium simultaneously. Therefore, this method could provide a new reference for the quality assess of multi components in Chinese materia medica.
