ABSTRACT

UPLC-Q-TOF-MS and serum pharmacochemistry were employed to study the migrating components in rat sera after intragastric administration of the water extracts of Puerariae Lobatae Radix(PLR) and Puerariae Thomsonii Radix(PTR). After the respective intragastric administration of PLR and PTR extracts, blood samples were collected from the orbital vein. The serum samples were treated by protein precipitation method with methanol and acetonitrile at a ratio of 1∶1 and then passed through Agilent ZORBAX RRHD SB-C_(18) column(3 mm×100 mm, 1.8 μm) and Agilent SB-C_(18) pre-column(3 mm×5 mm, 1.8 μm) with 0.1% formic acid aqueous solution(A)-acetonitrile(B) as the mobile phase. The elution was performed at the flow rate of 0.25 mL·min~(-1), the column temperature of 40 ℃, and the injection volume of 2 μL. By comparison of the total ion chromatogram and secondary fragment ion information of PLR and PTR water extracts, PLR-and PTR-containing sera, and blank serum, we found 42 migrating components(including 17 prototype components and 25 metabolites) in the sera of rats treated with PLR and 35 migrating components(including 15 prototype components and 20 metabolites) in the sera of rats treated with PTR. Thirty-three common components were shared by the two treatments, including 13 prototype components and 20 metabolites. The differences of migrating components in the PLR-and PTR-treated rat sera provide a scientific basis for further study of the active components and quality markers of PLR and PTR.

ABSTRACT

Objective:To explore the effect of handicraft training administered over the Internet on sensation disorders and on the mental status and life quality of stroke survivors.Methods:A total of 75 stroke survivors in the sequelae stage and with sensory disturbance were randomly divided into a general training group of 26 (group A), a handicraft training group of 26 (group B), and a handicraft training group of 23 using Internet instruction (group C). In addition to 40 minutes of routine physical and sensory training rehabilitation every morning, groups A and B were given traditional training and handicraft training, while group C was given handicraft training delivered over the Internet for 40 minutes every afternoon, five days a week for 4 weeks. The traditional training involved inserting wooden boards, plate grinding, as well as sorting beans. The handicraft training involved digital painting, making non-woven flowers, silk screening flowers and paper-rolling. Before and after the 4 weeks of treatment, all of the subjects were assessed using the Fugl-Meyer sensory assessment (FMA-S), the Hamilton Anxiety Scale (HAMA), the Modified Barthel Index (MBI), and the physical component summary scale (PCS) and mental component summary scale (MCS) of the 36-item short-form health survey.Results:After the treatment, significant improvement was observed in their average scores of all three groups in all of the assessments. Groups B and C showed significantly greater improvement in the average FMA-S, HAMA and MBI scores than group A. And the average HAMA and MCS scores of group C were significantly better than those of group B.Conclusion:Handicraft training delivered over the Internet can improve the sensory functioning, mental status and life quality of stroke survivors in the sequelae stage with sensory disturbance.

ABSTRACT

Alismatis Rhizoma(AR)is widely used in Chinese medicine,and its major bioactive components,tri-terpenes,reportedly possess various pharmacological activities.Therefore,it is very important to study the metabolism of triterpenes in vivo.However,the metabolism of AR triterpene extract has not been comprehensively elucidated due to its complex chemical components and metabolic pathways.In this study,an ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry method,which was based on the characteristic ions from an established database of known triterpenes,was used to analyze the major metabolites in rats following the oral administration of Alismatis Rhizoma extracts(ARE).As a result,a total of 233 constituents,with 85 prototype compounds and 148 metabo-lites,were identified for the first time.Hydrogenation,oxidation,sulfate and glucuronidation conjugation were the major metabolic pathways for triterpenes in AR.In addition,the mutual in vivo transformation of known ARE triterpenes was discovered and confirmed for the first time.Those results provide comprehensive insights into the metabolism of AR in vivo,which will be useful for future studies on its pharmacodynamics and pharmacokinetics.Moreover,this established strategy may be useful in meta-bolic studies of similar compounds.

ABSTRACT

BACKGROUND@#Recent genome-wide association studies have identified an important role of T-cell receptor α (TRA) gene in the development of narcolepsy type 1. However, the role of TRA haplotype polymorphisms in the symptomatic diversity of narcolepsy remains unclear. This study aimed to investigate whether TRA polymorphisms can influence the symptomatic diversity of narcolepsy.@*METHODS@#Totally, 903 patients with narcolepsy type 1 were included in the study. Patients were divided into different groups according to their symptoms. First, 13 genotyped single nucleotide polymorphisms in the TRA were assessed for their association with symptoms of narcolepsy. We used the Chi-square test to determine differences in genotype frequencies in patients with narcolepsy. Further, we identified the haplotypes and variations of the TRA and tested their association with the symptoms of narcolepsy using a logistic regression model.@*RESULTS@#According to the results of the logistic regression, TRA haplotypes TG and CT were significantly associated with auditory hallucination, with odds ratios of 1.235 (95% confidence interval [CI], 1.012-1.507) and 1.236 (95% CI, 1.012-1.511), respectively (P < 0.05).@*CONCLUSIONS@#The patterns of haplotype in TRA (haplotypes TG and CT) are associated with hypnagogic auditory hallucination in patients with narcolepsy type 1. However, further studies are needed to confirm our results and explore the underlying mechanisms.

ABSTRACT

Chronic low-back pain (CLBP) is one of the most common pain conditions. Current clinical guidelines for low-back pain recommend acupuncture for CLBP. However, there are very few high-quality acupuncture studies on CLBP in older adults. Clinical acupuncture experts in the American Traditional Chinese Medicine Association (ATCMA) were interested in the recent grant on CLBP research announced by the National Center for Complementary and Integrative Health. The ATCMA experts held an online discussion on the subject of real-world acupuncture treatments for CLBP in older adults. Seven participants, each with more than 20 years of acupuncture practice, discussed their own unique clinical experience while another participant talked about the potential mechanism of acupuncture in pain management. As a result of the discussion, a picture of a similar treatment strategy emerged across the participants for CLBP in older adults. This discussion shows that acupuncture may have complicated mechanisms in pain management, yet it is effective for the treatment of chronic pain involving maladaptive neuroplasticity; therefore, it should be effective for CLBP in older adults.

ABSTRACT

Few studies have focused on the cost of acupuncture treatments although acupuncture has become popular in the United States (U.S.). The purpose of the current study was to examine the out-of-pocket costs incurred from acupuncture services based on an online website, OkCopay.com. We examined descriptive statistics (range, median and 20% intervals) for the cost of acupuncture "first-time visits" and "follow-up visits" in 41 metropolitan regions in the U.S. The acupuncture prices of 723 clinics throughout 39 metropolitan regions were included, except for Birmingham, Alabama and Detroit, Michigan as there was no online data available at the time of the study for these two regions. The cost range for a first-time acupuncture visit was $15-400; the highest median was $150 in Charleston, South Carolina, while the lowest was $45 in St. Louis, Missouri. The top 10 cities for the highest median were: Baltimore, Washington, D.C., New York, San Francisco, San Jose, Boston, Atlanta, Seattle, Portland and Indianapolis, with the median $120, while the median for all 723 clinics was $112. For the follow-up visits, the cost range was $15-300; the highest median was $108 in Charleston, South Carolina, and the lowest $40 in Miami, Florida. The 10 cities with highest median follow-up acupuncture visit costs were: New York, Baltimore, New Orleans, Washington, D.C., Philadelphia, San Francisco, San Jose, Seattle, Boston and Atlanta, with the median $85, while for all 723 clinics the median price was $80. The estimation of the average gross annual income of each acupuncturist from the regions studied was $95,760, while the total annual cost of patients seeking acupuncture services in the U.S. was about $3.5 billion in 2018.

ABSTRACT

<p><b>BACKGROUND</b>Vulvodynia, or vulvar pain, is a common condition in women; however, there are few evidence-based clinical trials evaluating nonpharmacological therapies for this condition. Acupuncture is one complementary and integrative medicine therapy used by some patients with vulvodynia. This study evaluates two different acupuncture strategies for the treatment of vulvodynia and aims to evaluate whether either of the acupuncture protocols reduces vulvar pain, pain duration or pain with intercourse. The study also examines how long the effect of acupuncture lasts in women with vulvodynia.</p><p><b>METHODS/DESIGN</b>The study is designed as a randomized controlled trial, focused on two acupuncture protocols. Fifty-one patients who have had vulvodynia for more than 3 months will be recruited. Among them, 34 patients will be randomized into Groups 1a and 1b; those who are unwilling to receive acupuncture will be recruited into the standard care group (Group 2). Patients in Group 1a will have acupuncture focused on the points in the pudendal nerve distribution area, while patients in Group 1b will receive acupuncture focused on traditional (distal) meridian points. Patients in Group 2 will receive routine conventional treatments, such as using pain medications, local injections and physical therapies or other nonsurgical procedures. Acupuncture will last 45 min per session, once or twice a week for 6 weeks. The primary outcome measurement will be objective pain intensity, using the cotton swab test. The secondary outcome measurement will be subjective patient self-reported pain intensity, which will be conducted before cotton swab test. Pain intensities will be measured by an 11-point Numeric Pain Rating Scale. Pain duration and pain score during intercourse are recorded. Local muscle tension, tenderness and trigger points (Ashi points) are also recorded. All measurements will be recorded at baseline (before the treatment), at the end of each week during treatment and at the end of the 6 weeks. Follow-up will be done 6 weeks following the last treatment.</p><p><b>DISCUSSION</b>Results of this trial will provide preliminary data on whether acupuncture provides better outcomes than nonacupuncture treatments, i.e., standard care, and whether acupuncture focused on the points in pudendal nerve distribution, near the pain area, has better results than traditional acupuncture focused on distal meridian points for vulvodynia.</p><p><b>TRIAL REGISTRATION</b>Clinicaltrials.gov: NCT03481621. Register: March 29, 2018.</p>

ABSTRACT

A rapid and accurate method of UFLC-Q-TOF-MS/MS combined with multivariate statistical analysis was established for the identification of Ainsliaea fragrans from different origins in this study. The A. fragrans from different producing areas of Jiangxi, Yunnan, Henan and Jiangsu were determined by UFLC-Q-TOF-MS/MS in the negative ion mode. And the data of the study were analyzed by the Markerview and other software for the PCA and OPLS-DA cluster analysis as well as t test. The results of the principal component analysis(PCA)showed that the main components from different origins were well distinguished. And the results of multivariate statistical showed the differences and similarities between different producing areas. Besides, 40 different compounds were identified in the negative ion mode. This method for identifying A. fragrans from different producing areas has the advantages of rapid accuracy and simplicity, which laid the foundation for the evaluation of the quality of the A. fragrans.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the underlying mechanisms of cyclovirobuxinum D (Cvb-D) on alleviating cardiac hypertrophy in rats.</p><p><b>METHODS</b>Sprague-Dawley rats were randomly divided into 5 groups: control group; levothyroxine-induced cardiac hypertrophy group (model); levothyroxine-induced cardiac hypertrophy + Cvb-D group (Cvb-D); levothyroxine-induced cardiac hypertrophy + captopril group (captopril); levothyroxine-induced cardiac hypertrophy + SB203580 group (SB203580), n=10 for each group. Rats were daily administered the respective drugs continuously for14 days by gastric gavage. A rat model of cardiac hypertrophy was established by intraperitoneal injection of levothyroxine to investigate whether Cvb-D protects against cardiac hypertrophy by inhibiting the p38 mitogen-activated protein kinase (MAPK) signaling pathway and preventing apoptosis of cardiac cells.</p><p><b>RESULTS</b>Treatment with Cvb-D significantly deceased left ventricle hypertrophy, improved the histopathology, hemodynamic conditions, and cardiac function in rats with cardiac hypertrophy. Compared with the normal control group, in rats with cardiac hypertrophy, expression of bax in the heart and phospho-p38 MAPK protein levels were significantly up-regulated (P<0.01 or 0.05), whereas the bcl-2 protein level was down-regulated (P<0.01). In contrast, Cvb-D treatment reversed the changes in bax and phospho-p38 MAPK protein levels but increased the bcl-2 protein level (P<0.01 or 0.05), and these effects were similar to those of captopril and SB203580 (a specific p38MAPK inhibitor) treatment. Furthermore, both Cvb-D, captopril and SB203580 reduced mRNA expression of p38α, p38β, c-fos, and c-jun mRNA, and Cvb-D had a stronger effect (P<0.01).</p><p><b>CONCLUSION</b>These results demonstrate that Cvb-D protects against cardiac hypertrophy, which is possibly mediated by prevention of cardiac cell apoptosis and inhibition of the p38MAPK signaling pathway.</p>

ABSTRACT

Objective:To observe the effects of bama nectar in kidney-yang deficienct mice and on the mating ability and sperm counts of normal mice. Methods:The weight, body temperature, locomotor activity, cold-resistant,genital organ coefficient and lipid peroxidation of the hydrocortisone-induced kidney-yang deficient mice were detected. The genital organ ccoefficient, immune organ co-efficient and erectile function of the ovariectomized mice were detected. The mating ability and the sperm counts of normal mice were measured. Results:Compared with the model group, bama nectar obviously increased the weight, body temperature and locomotor ac-tivity of the hydrocortisone-induced kidney-yang deficient mice, and improved the locomotor activity, the organ coefficient of seminal vesicle, prostate gland, preputial gland and epididymis. Furthermore, bama nectar significantly increased the SOD activity in serum and reduced the level of MDA in serum when compared with the model group (P<0.05 or P<0.01). Compared with the model group, bama nectar could increase the organ coefficient of foreskin and thymus gland in the ovariectomized mice, and shorten the erec-tile latency (P<0. 05). Compared with the normal group, bama nectar improved the mating ability and the sperm counts of the male mice (P<0. 05 or P<0. 01). Conclusion:Bama nectar has beneficial effects on invigorating kidney and strengthening yang.

ABSTRACT

To study the pharmacokinetics and tissue distribution characteristics of α-hederin sodium salt in rats. 100 mg•kg⁻¹ α-hederin sodium salt was given to the rats by intragastric administration, and LC-MS/MS method was used to determine its concentration at different time in plasma and tissues. Plasma and tissue samples were treated with methanol protein deposition method. Main pharmacokinetic parameters were as follows: tmax (0.97±1.23) h, Cmax (222.53±57.28) μg•L⁻¹, AUC0-t (1 262±788.9) h•μg•L⁻¹, T1/2 (17.94±9.50) h. α-hederin can be detected in heart, liver, spleen, lung, kidney, brain, muscle and adipose. The results showed that α-hederin sodium salt was absorbed fast and eliminated slowly in rats after oral administration. It was widely distributed in body tissues and livers kept the highest concentrations among various tissues at different time, so it can be speculated that α-hederin may have certain targeting property on livers.

ABSTRACT

To explore the association of serum Dickkopf-1 (DKK-1) levels with the development of ankylosing spondylitis (AS) and rheumatic arthritis (RA) in humans, databases including PubMed, EBSCO, Springerlink, Ovid, WANFANG and China National Knowledge Infrastructure (CNKI) were searched to identify relevant studies. On the basis of rigorous inclusion and exclusion criteria, case–control studies of the relationships between serum DKK-1 levels and AS and RA published before December 2014 were enrolled. Statistical analyses were performed using Comprehensive Meta-analysis 2.0 (CMA 2.0). Seven case–control trials with a total of 300 AS patients, 136 RA patients and 232 healthy controls were included in this study. Meta-analysis results revealed that DKK-1 serum levels were significantly higher in AS patients than in normal controls (standard mean differences (s.m.d.)=0.301, 95% confidence interval (CI)=0.094–0.507, P=0.004), whereas no significant difference in DKK-1 serum levels was observed between RA patients and healthy controls (s.m.d.=0.798, 95% CI=−2.166–3.763, P=0.598). Serum DKK-1 level may be closely related to the development of AS but not of RA.
