ABSTRACT
OBJECTIVE@#To explore the effect of intermittent pneumatic compression(IPC) combined with 3M thermometer on the prevention of deep venous thrombosis(DVT) in patients with femoral intertrochanteric fracture.@*METHODS@#From March 2016 to August 2019, 127 patients with femoral intertrochanteric fractures who underwent proximal femoral nail antirotation(PFNA) were retrospectively analyzed. They were divided into two groups according to different methods of thrombus prevention and treatment. Among them, 63 patients in group A did not use IPC and 3M thermometer;64 cases in group B were treated with IPC combined with 3M thermometer. Color Doppler ultrasound was used to dynamically monitor the DVT and changes of lower limbs during perioperative period. The venous thrombosis of lower limbs was monitored at 0, 24, 72 h and > 72 h after operation(recheck every 3 days until discharge).@*RESULTS@#Occurrence of DVT of lower limbs after PFNA operation in two groups:there were 5 cases (7.8%) in group B and 20 cases (31.7%) in group A, there was significant difference between two groups (P=0.001). There was no significant difference in lower limb DVT between two groups at 0, 72 and > 72 h after operation(P>0.05), but the formation rate of group A was significantly higher than that of group B at 24 h after operation (P=0.049). There was no significant difference in DVT formation between group A and group B(P>0.05). However, the formation of DVT in group A was significantly higher than that in group B(P=0.012).@*CONCLUSION@#Intraoperative IPC combined with 3M thermostat can effectively prevent DVT of lower limbs in patients undergoing PFNA surgery.

In order to promote the standardization of traditional medicines in Laos， China and Laos jointly formed a census team to conduct resource survey， market survey， species identification and others of medicinal plants in Laos. According to the principles of nationality， tradition， effectiveness and commonness， 160 medicinal materials and 40 prescriptions were selected and collected into Lao Herbal Pharmacopoeia after recommendation， examination of experts and review by the established expert committee. Moreover， quality standards of traditional medicine and scientific and clear translation methods were formulated in line with the national conditions of Laos， and the contents were finally compiled according to the 2010 edition of Chinese Pharmacopoeia. The promulgation and implementation of Lao Herbal Pharmacopoeia is a successful example of cooperation in the field of health care between China and Laos， which is conducive to promoting mutually beneficial cooperation between China and Association of Southeast Asian Nations （ASEAN） countries in the field of traditional medicine， and making traditional medicine play a greater role in the medical and health services of ASEAN countries.
ABSTRACT
Andrographis Herba is a commonly used plant medicine, and has been recorded in pharmacopeias of different countries. However, there are some differences in the quality standards. Based on this, this paper compare the quality standards of Andrographis Herba between Chinese Pharmacopoeia, Hong Kong Chinese Materia Medica Standards, United States Pharmacopoeia, European Pharmacopoeia and Indian Pharmacopoeia, including origin, botanical characteristics, identification(microscopic identification and chromatographic identification), content determination, specific test(such as impurities, loss on drying, extractives, pesticides, heavy metals, mycotoxins, and other items) and storage requirements, so as to provide a reference for studying international quality standards of Andrographis.

Spatholobi Caulis, the vine stem of Spatholobus suberectus and widely used in China and Southeast Asian nations, has the effects on nourishing the blood and promoting blood flow, regulating menstruation and relieving pain, and invigorating the nerves. Through consulting the herbal textual and local chronicles, we summarized the original textual research and medicinal evolution on Spatholobi Caulis to analyze the changes of varieties in different historical periods. Further, the major active ingredient in Spatholobi Caulis was discussed. According to the literature to date, 60 flavonoids compounds have been isolated and could be divided into isoflavones, dihydroflavones, flavanols, dihydroflavonols, procyaninides, chalcones, pterocarpans, isoflavanols, isoflavanones and aurone according to their molecular structures. These indicative ingredients in Spatholobi Caulis showed pharmacological activities on regulation of the blood system, anti-tumor, anti-oxidation, anti-virus, anti-bacteria and inhibition of melanin deposition. This review will provide reference and basis for the sustainable use of resources and industry development on Spatholobi Caulis.
ABSTRACT
Protection of traditional Chinese medicine (TCM) resources is the foundation of sustainable development of TCM industry, which includes the in-situ and ex-situ conservation. The development of TCM resource ex-situ conservation was reviewed, and hotpots in the conservation and its development practices were analyzed. Therefore national TCM resource ex-situ conservation systems were proposed, including the establishment of TCM resources introduction gardens, TCM resource in vitro conservation library and TCM resource bio-information sharing platform, rational distribution of TCM resources ex-situ conservation agencies, along with the advancement of TCM varieties breeding, and the perfection of Chinese herbal medicines seed and seedlings market, which are of significant importance on the guidance of TCM resource ex-situ conservation development.
ABSTRACT
According to the transcriptome dataset of Panax notoginseng, the key geranylgeranyl pyrophosphate synthase gene (GGPPS) in terpenoid backbone biosynthesis was selected to be cloned. Using specific primer pairs combining with RACE (rapid amplification of cDNA ends) technique, the full-length cDNA sequence with 1 203 bp, which containing a 1 035 bp open reading frame, was cloned and named as PnGGPPS. The corresponding full-length DNA sequence contained 2 370 bp, consisted of 1 intron and 2 exons. The deduced protein PnGGPPS contained 344 amino acids and shared more than 73% identity with GGPPS from Ricinus communis and Salvia miltiorrhiza. PnGGPPS also had specific Aspartic acid enrichment regions and other conserved domains, which belonged to the Isoprenoid-Biosyn-C1 superfamily. The quantitative real-time PCR showed that PnGGPPS expressed in different tissues of 1, 2, 3 years old root, stem, leaf and 3 years old flower, and the expression level in 3 years old leaf was significant higher than that in other organs, which suggested that it might not only be involved in the regulation of the growth and development, but also be associated with the biosynthesis of chlorophyll and carotenoids, the development of chloroplast, the shade habit and the quality formation of P. notoginseng.
