Rapid identification and differential markers of Curcumae Radix decoction pieces of different sources based on Heracles Neo ultra-fast gas phase electronic nose / 中国中药杂志

Since Curcumae Radix decoction pieces have multiple sources, it is difficult to distinguish depending on traditional cha-racters, and the mixed use of multi-source Curcumae Radix will affect its clinical efficacy. Heracles Neo ultra-fast gas phase electronic nose was used in this study to quickly identify and analyze the odor components of 40 batches of Curcumae Radix samples from Sichuan, Zhejiang, and Guangxi. Based on the odor fingerprints established for Curcumae Radix decoction pieces of multiple sources, the odor components was identified and analyzed, and the chromatographic peaks were processed and analyzed to establish a rapid identification method. Principal component analysis(PCA), discriminant factor analysis(DFA), and soft independent modeling cluster analysis(SIMCA) were constructed for verification. At the same time, one-way analysis of variance(ANOVA) combined with variable importance in projection(VIP) was employed to screen out the odor components with P<0.05 and VIP>1, and 13 odor components such as β-caryophyllene and limonene were hypothesized as the odor differential markers of Curcumae Radix decoction pieces of diffe-rent sources. The results showed that Heracles Neo ultra-fast gas phase electronic nose can well analyze the odor characteristics and rapidly and accurately discriminate Curcumae Radix decoction pieces of different sources. It can be applied to the quality control(e.g., online detection) in the production of Curcumae Radix decoction pieces. This study provides a new method and idea for the rapid identification and quality control of Curcumae Radix decoction pieces.

Efficacy of external treatment of integrated traditional Chinese and Western medicine on chloasma / 中华医学美学美容杂志

Objective:To explore the efficacy of external treatment of integrated traditional Chinese and Western medicine on melanized type complicated with vascularized type of chloasma.Methods:A total of 82 patients (aged 26-50 years, with an average age of 44.5 years) with melanized type complicated with vascularized type of chloasma were selected, and randomly divided into groups: 28 cases in the traditional Chinese medicine control group were treated with traditional Chinese medicine pourmask combined with surrounded facial acupuncture; 26 cases in Western medicine control group underwent wet compress with 0.5% tranexamic acid solution. In the integrated Chinese traditional and Western medicine treatment group, 28 cases were treated with 2 regimens. After 8 weeks, MASI score was carried out, and vascular hyperplasia in skin lesions was observed by polari-light skin scope.Results:After treatment, the MASI scores in the three groups were all decreased, and the decreasing rate of MASI scores from high to low was as follows: Integrated Chinese traditional and Western medicine treatment group (8.60±4.53) > TCM control group (6.26±3.20) > Western medicine control group (4.39±2.11). After treatment, the vascular hyperplasia scores in the three groups were all decreased, and the value of vascular hyperplasia in the integrated Chinese traditional and Western medicine treatment group (2.57±0.63) and Western medicine control group (1.55±0.51) was greater than that in TCM control group (0.96±0.51), but there was no significant difference between the integrated Chinese traditional and Western medicine treatment group and Western medicine control group.Conclusions:External treatment of integrated traditional Chinese and Western medicine is effective in the treatment of melanized type complicated with vascularized type of chloasma, and wet compress with tranexamic acid solution can inhibit vascular hyperplasia in patients with chloasma.

Quality value transmitting of substance benchmarks of Zhuru Decoction / 中国中药杂志

A total of 18 batches of Zhuru Decoction samples were prepared. Chromatographic fingerprints were established for Zhuru Decoction and single decoction pieces, the content of which was then determined. The extraction rate ranges, content, and transfer rate ranges of puerarin, liquiritin, and glycyrrhizic acid, together with the common peaks and the similarity range of the fingerprints, were determined to clarify key quality attributes of Zhuru Decoction. The 18 batches of Zhuru Decoction samples had 25 common peaks and the fingerprint similarity higher than 0.95. Puerariae Lobatae Radix, Glycyrrhizae Radix et Rhizoma, and Zingiberis Rhizoma Recens had 21, 3, and 1 characteristic peaks, respectively. The 18 batches of samples showed the extraction rates within the range of 18.45%-25.29%. Puerarin had the content of 2.20%-3.07% and the transfer rate of 38.5%-45.9%; liquiritin had the content of 0.24%-0.85% and the transfer rate of 15.9%-37.5%; glycyrrhizic acid had the content of 0.39%-1.87% and the transfer rate of 16.2%-32.8%. In this paper, the quality value transmitting of substance benchmarks of Zhuru Decoction was analyzed based on chromatographic fingerprints, extraction rate, and the content of index components. A scientific and stable method was preliminarily established, which provided a scientific basis for the quality control and formulation development of Zhuru Decoction.

Acupuncture Treatment for Post-Stroke Dysphagia: An Update Meta-Analysis of Randomized Controlled Trials / 中国结合医学杂志

<p><b>OBJECTIVE</b>To explore the effectiveness and safety of acupuncture in patients with post-stroke dysphagia by an update meta-analysis.</p><p><b>METHODS</b>Potentially eligible RCTs aimed to evaluate the effects of acupuncture vs. non-acupuncture treatments, such as rehabilitation training or routine medication on the swallowing difficulty after stroke were searched from PubMed, Cochrane Library, China National Knowledge Infrastructure, and other database from the earliest record to June 2016. Patient demographics, regimens for acupuncture, type of controls, methods of randomization, and measurements of the clinical symptoms of dysphagia were retrieved. The relative risk (RR) and 95% confidence interval (CI) of effective rate of dysphagia was calculated after intervention performed following admission. Subgroup analyses and a metaregression analysis were performed to describe the heterogeneity.</p><p><b>RESULTS</b>Twenty-nine RCTs comprising 2,190 patients were included. The included studies had a medium quality grade based on the Consolidated Standards of Reporting Trials (CONSORT) and Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA) checklist. Acupuncture therapy provided a higher effective rate compared with nonacupuncture treatments [RR=1.33, 95% confidence interval (CI), 1.25 to 1.43]. Subgroup and meta-regression analyses suggested that acupuncture intensity and measurement method were main sources of heterogeneity and resulted in a significant difference for pooled effect size. No severe adverse events were documented in these RCTs.</p><p><b>CONCLUSIONS</b>Our meta-analysis provides a new evidence supporting the efficacy and safety of acupuncture in treatment to post-stroke dysphagia in short-term compared with rehabilitation or medication.
