[DNA fingerprinting identification of bile power(bile)medicines].

The pig bile powder, bovine bile powder, snake bile, sheep bile, goose bile powder, and bear bile powder were contained by the Chinese Pharmacopoeia. The bile power medicine has a long history in traditional Chinese medicine and definite effect. However, the medicine of bile powder(bile) are similar in morphology. Besides, many medicine lack specific microscopic identification characteristics and chemical characteristics. There is a risk of adulteration, especially when the fake medicine were mixed in authentic medicine, it is difficult to detection. The key to control the quality and ensures the clinical efficacy is the good or bad, true or false of the bile power medicine. The STR typing technology is a method that according to differential typing of PCR amplified lengths to compare and identify individual organisms. Based on the principle of STR typing, the easily, rapid DNA fingerprinting method to identify the bile power and adulteration was established.The original animal or bile powder of pigs, cattle, sheep, chickens, ducks, geese, snakes, bears, fish were collected, the 12 S-L1091/12 S-H1478 and 16 S-L3428/16 S-H3667 was obtained by sifted, the DNA fingerprinting of the bile power and adulteration was obtained by STR typing. Every species has different STR fingerprints, so different species can be identified. Besides, the fingerprints have both the authentic and fake's information, the adulteration of authentic and fake can be identified. Therefore, the method to identify the bile power and adulteration was achieved through the combination of two primers. The DNA fingerprinting method established in this study can also be used for other animal medicine.

[Effects of different stocking density and diet on development of Bufo gargarizans tadpoles].

The effects of four different stocking densities and five different diets on the growth of Bufo gargarizans tadpoles were studied to determine the optimum stocking density and diet. For stocking density experiment, the tadpoles were fed respectively at different density of 200, 500, 1 000 and 2 000 tadpoles per square meter. For diet experiment, the tadpoles were divided into five groups fed respectively with five different diets. The body weight, snout-vent length and tail length were measured every seven days, and mortality was recorded. The results showed that: the survival rates of tadpole before metamorphosis and after metamorphosis were from 68.7% to 96.3% and from 5.7% to 36.0%, respectively; the optimum stocking density is 1 000 tadpoles per square meter for the stocking density had no effect on the survival rate of tadpole before metamorphosis, and the tadpoles had the relative large body weight and survival numbers in 1000 tadpoles per square meter; the diet Ⅱ(37.9% crude protein and 5.7% crude fat), Ⅳ (25.1% crude protein and 4.0% crude fat), and Ⅴ (egg yolk) were all the optimum diets for the diet had no effect on the survival rate of tadpole before metamorphosis and the tadpoles fed with three kinds of diet above had relatively large body weight, and one of these three diets based on their availability and cost should be adopted during breeding period.

[Identification of original species of Mantidis Oötheca (Sangpiaoxiao) based on DNA barcoding].

Both market research and literature reports both found that the ootheca of mantodea was all used as medicine. However, Chinese Pharmacopoeia only records the ootheca of three mantis species. The clinical use of ootheca unrecorded in Chinese Pharmacopoeia, will pose potential risks to drug safety. It's urgent to identify the origin of Mantidis Oötheca. The current researches about original animal in Mantidis Oötheca are based on morphology and unanimous. DNA barcoding fill gaps of the traditional morphological identification, which is widely used in animal classification studies. This study first use DNA barcoding to analyze genetic distance among different Mantidis Oötheca types, align COI sequences between mantis and Mantidis Oötheca and construct the phylogeny tree. The result confirmed that Tenodera sinensis and Hierodula patellifera were the origin insects of Tuanpiaoxiao and Heipiaoxiao, respectively, and Statilia maculate and Mantis religiosa were the origin insects of Changpiaoxiao.

[Study on morphology and anatomy of Akebia trifoliate seeds].

Akebia trifoliate has been reported to have many pharmacological activities and the roots, petioles and seeds are used to different symptoms. However, the structure and anatomy of its seeds was almost not reported until now. In the present study, we investigated the morphological characters of the fruit and seed, and the anatomical characters of the testa, micropyle, embryo and endosperm, which could provide evidences for the study on classification, identification and application of A. trifoliate. Our results showed that the testa of A. trifoliate consisted of an epidermic cell layer, the sclerenchyma cells layer, the parenchyma cells layer and an innermost pigment layer. At the micropylar region, the outermost epidermal cells were specialized the white caruncle-like structure and the testa included a lot of lignified tissues. Endosperm comprises two layer cells. Outermost yellowish-brown layer cells contains lots of fat droplets, and innermost white layer cells contains lots of aleurone grains and crystalloids.

[DNA barcoding application of mitochondrial COI gene sequence in medicinal fish of Culter (Pisces: Cyprinidae)].

The sequence variation of medicinal fish of Culter (Pisces: Cyprinidae) was analyzed by using cytochrome c oxidase subunit I (COI) sequencing collected from different regions of the Yangtze River basin, and we examine whether barcoding of COI can be used to discriminate medicinal fish of Culter. The AT content in the COI region of medicinal fish of Culter was higher than that of GC, which was similar with other species of Cypriniformes. Ninty-six percent of nucleotide changes were observed at the 3rd codon position of COI sequence, but the amino acid compositions translated by COI sequences of all Culter fish stayed the same. It is suggested that most synonymous mutations might occur at the 3rd position. The average Kimura-2-parameter (K2P) distance within-species was lower than 1%, and the K2P distance of pairwise-species was 10 times as much as that of within-species. The phylogenetic tree estimated by Neighbour-joining method indicated that species within genera invariably clustered, and generally so did individuals within species. Individuals from operational taxonomic units designated as different Culter species, supporting morphological evidence for each of these being separate species. It is suggested that the COI barcoding can be used to identify medicinal fish species of Culter.

CFD simulation of water vapour condensation in the presence of non-condensable gas in vertical cylindrical condensers.

This paper presents the simulation of the condensation of water vapour in the presence of non-condensable gas using computational fluid dynamics (CFD) for turbulent flows in a vertical cylindrical condenser tube. The simulation accounts for the turbulent flow of the gas mixture, the condenser wall and the turbulent flow of the coolant in the annular channel with no assumptions of constant wall temperature or heat flux. The condensate film is assumed to occupy a negligible volume and its effect on the condensation of the water vapour has been taken into account by imposing a set of boundary conditions. A new strategy is used to overcome the limitation of the currently available commercial CFD package to solve the simultaneous simulation of flows involving multispecies and fluids of gas and liquid in separate channels. The results from the CFD simulations are compared with the experimental results from the literature for the condensation of water vapour with air as the non-condensable gas and for inlet mass fraction of the water vapour from 0.66 to 0.98. The CFD simulation results in general agree well with the directly measured quantities and it is found that the variation of heat flux in the condenser tube is more complex than a simple polynomial curve fit. The CFD results also show that, at least for flows involving high water vapour content, the axial velocity of the gas mixture at the interface between the gas mixture and the condensate film is in general not small and cannot be neglected.
