This paper explored the specific peptides from Bubali Cornu by ultra-performance liquid chromatography-tandem mass spectrometry and based on mathematics set theory. Following the profile analysis of peptides from Bubali Cornu, Bovis Grunniens Cornu, Caprae Hircus Cornu, and Suis Cornu by nano LC-LTQ-Obitrap-MS after digestion with trypsin, the relationship of peptide composition among different samples was analyzed using the mathematics set theory. The ones that existed only in the Bubali Cornu set rather than in any other set were considered as the specific peptides of Bubali Cornu. The further bioinformatic analysis revealed four specific peptides from Bubali Cornu, whose specificity was verified by UPLC-QQQ-MS. The results showed that these four peptides could be used for distinguishing Bubali Cornu from Caprae Hircus Cornu and Suis Cornu. This study has provided a rapid and simple method for seeking the specific peptides in animal medicines, which can be utilized for quality evaluation of animal medicines, thus making them authenticable and traceable.

The present study comprehensively compared the content of chondroitin sulfate in Cervi Cornu Pantotrichum(CCP) and Cervi Cornu(CC) of different specifications and explored the feasibility of chondroitin sulfate as an indicator to distinguish between CCP and CC. Twenty-two batches of CCP of different specifications(two-branched velvet antler and three-branched velvet antler) from 15 habitats, CC from 6 habitats, and 60 batches of CCP slices prepared from different parts(wax slices, powder slices, gauze slices, and bone slices) were collected. High-performance liquid chromatography(HPLC) was used to determine chondroitin sulfate content in CCP and CC of different specifications. Cluster analysis was used to classify CCP slices of different specifications. The results showed that CCP contained abundant chondroitin sulfate. The average content of chondroitin sulfate was 2.35 mg·g~(-1) in two-branched velvet antler and 1.79 mg·g~(-1) in three-branched velvet antler, significantly higher than 0.11 mg·g~(-1) in CC. Chondroitin sulfate content in wax slices, powder slices, gauze slices, and bone slices were 7.81, 8.39, 1.33, and 0.54 mg·g~(-1), respectively. Cluster analysis showed that gauze slices and bone slices could be clustered into one category and distinguished from wax slices and powder slices. CCP slices prepared from different parts could be separated well through chondroitin sulfate content. Based on the five principles of Q-marker selection, chondroitin sulfate can be used as a potential Q-marker for the identification of CCP and CC, as well as a potential quality indicator for CCP slices of different specifications(wax slices, powder slices, gauze slices, and bone slices). This research provides data support for CCP quality evaluation.

Cervi Colla, deer's gelatin, had two kinds of original sources historically, including the skin and antler of deer, known as Cervi Corii Colla(Lupijiao, LPJ) and Cervi Cornus Colla(Lujiaojiao, LJJ) respectively.LJJ is the mainstream of the market, while LPJ is only used by common people in Guizhou and Jilin etc. This article sorted out the ancient and modern literature(since Rites of the Zhou in Zhou Dynasty) on Cervi Colla and conducted the herbalogical study. The results of the study include:① In ancient China, there were six types of commonly-used Colla derived from six animals, including deer, horse, cow, rat, fish and rhinoceros. Cervi Colla was ranked the most top among them, and it was often used as adhesive to make bow and Chinese inksticks and more commonly used as a medicine.Cervi Cornus Colla was first described as a medicinal by the name "Bai Jiao"(white gelatin)in The Divine Husbandman's Classic of Material Medica(Shen Nong Ben Cao Jing).② Initially, both the skin and antler were used as raw materials to make Cervi Colla, but antler became the only raw material, and deer skin disappeared from the mainstream of raw materials for Cervi Colla. This can be attributed to other diverse and luxurious uses of the skin, such as making dress and hats, etc., and the easy accessibility of deer antlers. ③ The sources of Cervi Colla were not limited to Cervus elaphus(red deer) or C. nippon(sika deer), and it also included animal from the family Cervidae, such as Elaphurus davidianus(elk) and C. unicolor(sambar). ④ The processing method was passed down from ancient times to the present, and no significant changes had occurred. ⑤ LPJ and LJJ had many similar effects, and their nature was both warm. The effect of LJJ was to warm the liver and kidney, replenish vital essence and blood, and to reinforce Yang. While the effect of LPJ was to reinforce both Yin and Yang, replenish blood, and stop bleeding. It has a unique advantage for both reinforcing Yin and Yang. The findings of this paper can provide support for the promotion of LPJ and the development of its medicinal value.

Eleven steroid hormones (SHs: androstene-3,17-dione, estrone, β-estradiol, α-estradiol, testosterone, dehydroepiandrosterone, 17á-hydroxyprogesterone, medroxyprogesterone, megestrol acetate, progesterone, and androsterone) were detected from New Zealand deer (Cervus elaphus var. scoticus) velvet antler (NZA, 鹿茸). A method for the quantification of eleven SHs was established by using ultraperformance liquid chromatography (UPLC)-MS/MS. The linearities (R² > 0.991), limits of quantification (LOQ values, 0.3 ng/mL to 23.1 ng/mL), intraday and interday precisions (relative standard deviation: RSD < 2.43%), and recovery rates (97.3% to 104.6%) for all eleven SHs were determined. In addition, a method for the quantification of three 7-oxycholesterols (7-O-CSs: 7-ketocholesterol, 7α-hydroxycholesterol, and 7β-hydroxycholesterol) in the NZA was established by using an HPLC-photodiode array (PDA) method. The linearities (R² > 0.999), LOQ values (30 ng/mL to 350 ng/mL), intraday and interday precisions (RSD < 1.93%), and recovery rates (97.2% to 103.5%) for the three 7-O-CSs were determined. These quantitative methods are accurate, precise, and reproducible. As a result, it is suggested that the five steroid compounds of androstene-3,17-dione, androsterone, 7-ketocholesterol, 7α-hydroxycholesterol, and 7β-hydroxycholesterol could be marker steroids of NZA. These methods can be applied to quantify or standardize the marker steroids present in NZA.

We identified the echinostome metacercariae in Chinese mystery snails, Cipangopaludina chinensis malleata, from Xiengkhuang Province, Lao PDR with morphologies of adult worms recovered. Total 20 snails were examined with artificial digestion method and then the collected metacercariae were orally infected to a mouse and a rat. Adult worms recovered from experimental animals were observed with a light microscope and a SEM. The metacercariae were round, 125×123 μm in average size, with a moderately thick cyst wall, collar spines distributed in the head collar and excretory granules in 2 canals of excretory tube. Adult flukes (3-week-old in a rat) were elongated, ventrally curved and 5.310×1.023 mm in average size. Head collar distinct, bearing 43 collar spines with 5 end group ones on each side. Oral sucker subterminal, prepharynx very short, pharynx well developed, and esophagus relatively short. Cirrus sac well developed, with a saccular seminal vesicle, and ventral sucker very large. Ovary round and on the median line of the body. Testes tandom and elongated. Eggs operculated, elliptical and 90×57 μm in average size. In the SEM observation, the head crown prominent, with 43 collar spines resembled with horns of younger stag. Scale-like tegumental spines were densely distributed on the surface between the head collar and ventral sucker, and their densities were decreased posteriorly. Conclusively, the metacercariae detected in C. chinensis malleata from Lao PDR were identified as those of Echinostoma macrorchis based on the morphological characteristics of adult worms.

BACKGROUND: Thin or damaged endometrium causes uterine factor-derived infertility resulting in a failure of embryonic implantation. Regeneration of endometrium is a major issue in gynecology and reproductive medicine. Various types of cells and scaffolds were studied to establish an effective therapeutic strategy. For this type of investigations, production of optimal animal models is indispensable. In this study, we tried to establish various murine uterine damage models and compared their features. METHODS: Three to ten-week-old C57BL/6 female mice were anesthetized using isoflurane. Chemical and mechanical methods using ethanol (EtOH) at 70 or 100% and copper scraper were compared to determine the most efficient condition. Damage of uterine tissue was induced either by vaginal or dorsal surgical approach. After 7-10 days, gross and microscopic morphology, safety and efficiency were compared among the groups. RESULTS: Both chemical and mechanical methods resulted in thinner endometrium and reduced number of glands. Gross morphology assessment revealed that the damaged regions of uteri showed various shapes including shrinkage or cystic dilatation of uterine horns. The duration of anesthesia significantly affected recovery after procedure. Uterine damage was most effectively induced by dorsal approach using 100% EtOH treatment compared to mechanical methods. CONCLUSION: Taken together, murine uterine damage models were most successfully established by chemical treatment. This production protocols could be applied further to larger animals such as non-human primate.

This present study is to detect the content of free thiols(-SH) in the horn derived traditional Chinese medicines( TCMs) from different animals and different regions by using fluorescence derivatization method. TCEP was used as a disulfide bond reducing agent,while SBD-F as a derivatization reagent. Fluorescent spectrophotometry was used to determine the content of-SH,and the maximum excitation wavelength and emission wavelength were set as 375 and 510 nm,respectively. As a result,under the optimized condition,the extraction of Caprae Hircus Cornu showed the highest free-SH concentration,followed by Bovis Grunniens Cornu,Bubali Cornu,and Elaphuri Davidiani Cornu. In the present study,we point out that the-SH-contained components might be the most important material basis in animal horn derived TCMs. With good accurate,sensitive and rapid properties,the present method can provide reference basis for the quality evaluation of animal horn derived TCMs and guides for the investigation on effective material basis.
