Traditional medicinal knowledge in Lancang-Mekong River:a case study in Lancang Lahu autonomous county / 中国中药杂志

Lancang Lahu autonomous county, where the Lancang-Mekong River flows by, was selected as the case site to investigate the traditional medicinal knowledge(TMK). A comparison of TMK between Lancang county and other places in the Lancang-Mekong sub-region was conducted. Research on TMK has been seldom reported although there are abundant medicinal resources in this sub-region. The key informant interview and other methods have been adopted in the field surveys in the past six years. The investigation revealed that there was rich TMK and various herbal medicine resources in Lancang county. A total of 220 folk prescriptions have been collected, which were normally simple with easy processing methods and usages, and most raw materials were freshly used. As for medicinal plants, 121 species in 67 families have been documented. Other findings included that TMK in Lancang county was remained at the level of medication based on experience only. The processing methods of herbal medicines were simple and the bioactive ingredients were not clear. Without text and cultural support for self-teaching, coupled with conservative inheritance, it resulted in massive losses of TMK. The folk doctors have accumulated their factions based on self-study or ancestral experience. There was different treatment experience among folk doctors, but the safety and effectiveness should be paid attention to. The folk doctors used various herbal medicines, but there was a lack of standards or specifications for quality control. Given the problems existing in inheritance and development, conservation strategies were proposed in the present study.

Feasibility Study of Intelligent Automatic Registration Ultrasound-CT/MR Fusion Imaging Based on Liver Surface / 中山大学学报(医学科学版)

@#【Objective】To explore the feasibility and simplicity of intelligent automatic registration ultrasound-CT/ MR fusion imaging based on liver surface in localization of focal liver lesions. 【Methods】 Thirty patients with detected focal liver lesions by contrast- enhanced CT or MR were enrolled for ultrasound- CT/MR fusion imaging using the PercuNav fusion imaging system in PHILPS EPIQ7. Both intelligent automatic registration ultrasound- CT/MR fusion imaging based on liver surface（intelligent method）and the conventional internal plane method（manual method）were used for ultrasound-CT/MR fusion imaging. The success rate of registration，the initial registration error and the times of fine-tuning were compared between these two methods.【Results】In all 30 patients，the success rates of registration were both 96.67%（29/30）using intelligent method and manual method. There was no significant difference between these two methods when compared the initial registration error and the times of fine- tuning （P>0.05）. According to the further stratified analysis，in 10 lesions in the left liver，the initial registration error of the manual method was less than that of intelligent method，the difference was statistically significant（P=0.00）. Although the times of fine-tuning of the manual method was less than that of intelligent method，there was no statistically significant difference（P=0.09）；In 20 lesions in the right liver，the initial registration error and the times of fine-tuning of the intelligent method were superior to those of the manual method. The differences were statistically significant （P<0.05）. 【Conclusion】 Intelligent automatic registration ultrasound- CT/MR fusion imaging based on liver surface is a feasible method with high success rate for ultrasound-CT/MR fusion imaging. Compared with the conventional internal plane method，the fusion imaging process is more simple and efficient for the lesions in right liver. It helps to reduce experience dependence of fusion imaging for the operators.

The association between the whole blood riboflavin level and the occurrence, development and prognosis of esophageal squamous cell carcinoma / 中华预防医学杂志

Objective@#To investigate the association between the whole blood riboflavin level and the occurrence, development and prognosis of esophageal squamous cell carcinoma (ESCC) in China. @*Methods@#From March 2014 to September 2018, ESCC patients from three hospitals (the Affiliated Hospital of Medical College of Shantou University, Shantou Central Hospital in Southern Chaoshan area and First Affiliated Hospital of Zhengzhou University in Northern Taihang Mountain) were selected as a case group; non-esophageal patients who had a physical examination were selected as a control group. The case and control group were paired by age (±5 years) and a 1:1 ration. A total of 1 528 subjects were enrolled including 764 patients in the case group and 764 patients in the control group. About 3-5 ml venous blood samples were collected, and the erythrocyte glutathione reductase activity coefficient (GRAC) was measured to assess the whole blood riboflavin level. A multivariate conditional logistic regression model was used to analyze the association between the GRAC and the risk of ESCC. The association between the GRAC and the prognosis of ESCC was analyzed by using Cox proportional risk regression model based on 288 patients with complete survival data. They were divided into two groups, the high GRAC group (GRAC≥7.87) group and the low GRAC group (GRAC<7.87) according to the strongest correlation between the total survival time, survival outcome and GRAC (GRAC=7.87). @*Results@#Among the 1 528 patients, 958 patients were from Southern Chaoshan area, including 479 patients in the case group with an average age about (59.90±9.34) years and 479 patients in the control group with an average age about (59.55±8.77) years. Other 570 patients were from Northern Taihang Mountain area, including 285 patients in the case group with an average age (58.39±5.19) years and 285 patients in the control group with an average age about (58.74±4.57) years. The multivariate conditional logistic regression showed that the OR (95%CI) of the GRAC and the risk of ESCC was 1.009 (0.998-1.019). The Cox proportional hazard regression model analysis showed that the HR (95%CI) of the high GRAC group was 1.712 (1.034-2.824) compared with the low GRAC group in the 50-70 years group. @*Conclusion@#The whole blood riboflavin level might not be associated with the occurrence of ESCC. The high whole blood riboflavin level would be more beneficial to the prognosis of ESCC patients aged 50-70 years.

Studies on volatile oils compounds of Acorus macrospadiceus based on GC-MS, an ethnomedicinal and food plant used by local people in southwest China / 中国中药杂志

Acorus macrospadiceus is a common medicinal and food plant used different ethnic groups in Guizhou and surrounding areas. In this paper, the leaf and rhizome tissues of A. macrospadiceus were hydro-distilled to extract the volatile oils. The chemical constituents of these oils were analyzed by GC-MS and identified using the NIST 14.0 & NIST 14.0s mass spectral libraries. The relative contents of chemical constituents from the different plant parts were determined by area normalization. The analysis of A. macrospadiceus volatile oils resulted in the identification of 25 compounds from the leaf and 36 compounds from the rhizome. The identified compounds accounted for 97.85% of the leaf essential oil content and 97.18% of the rhizome essential oil content. The main volatile constituent of A. macrospadiceus was identified as estragole (93.56% of total oil content in leaf and 71.62% of total oil content in rhizome). Fourteen compounds were found to be common to essential oils of both leaf and rhizome. However, the relative amounts of these compounds were significantly different between the plant parts; the remaining identified compounds were unique to each part. This comparison of volatile oils from the different parts of A. macrospadiceus can serve as a reference for future development. Because of the higher estragole content and better harvesting sustainability of the leaves compared to rhizomes, the leaves of A. macrospadiceus deserve consideration for sustainable development. However, when we use it as a medical plant, we should draw a distinction between it with A. tatarinowii.

Identification of crocus sativus and its adulterants from Chinese markets by using DNA barcoding technique

Background: saffron [Crocus sativus L.] is a common but very expensive herbal medicine. As an important traditional medicine, it has an outstanding effect in treating irregular and painful menstruation. Recently, the over-demand tendency of saffron results in an unusual phenomenon in the medicinal markets. Adulterants and saffron-like substitutes are intentionally mixed into medicinal markets and pharmacies or online stores, affecting drug safety and food quality

Objectives: Our study aimed to identify saffron from its adulterants via DNA barcoding

Materials and Methods: Samples [13 saffron + 4 others containing Carthamus tinctorius or Chrysanthemum x morifolium] obtained from 12 different provinces of China. Through DNA barcoding, samples were compared using three candidate markers, trnH-psbA, rbcL-a and ITS2

Results: trnH-psbA and rbcL-a were capable of distinguishing different accessions. ITS2 could identify samples even at intra-specific level. According to these three barcodes, four samples were identified saffron-like substitutes

Conclusions: the adulterant rate in Chinese markets reaches as high as 33.33% that may cause health risks and further may reduce saffron efficacy once is being used as herbal remedy. In order to make a distinction between C. sativus with other genera as adulterants, DNA barcoding is suggested
