Cervi Cornu Pantotrichum is a precious animal-derived Chinese medicinal material, while there are often adulterants derived from animals not specified in the Chinese Pharmacopeia in the market, which disturbs the safety of medication. This study was conducted with the aim of strengthening the quality control of Cervi Cornu Pantotrichum and standardizing the medication. To achieve digital identification of Cervi Cornu Pantotrichum from different sources, a digital identification model was constructed based on ultra-high performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry(UHPLC-QTOF-MS~E) combined with an adaptive boosting algorithm(Adaboost). The young furred antlers of sika deer, red deer, elk, and reindeer were processed and then subjected to polypeptide analysis by UHPLC-QTOF-MS~E. Then, the mass spectral data reflecting the polypeptide information were obtained by digital quantification. Next, the key data were obtained by feature screening based on Gini index, and the digital identification model was constructed by Adaboost. The model was evaluated based on the recall rate, F_1 composite score, and accuracy. Finally, the results of identification based on the constructed digital identification model were validated. The results showed that when the Gini index was used to screen the data of top 100 characteristic polypeptides, the digital identification model based on Adaboost had the best performance, with the recall rate, F_1 composite score, and accuracy not less than 0.953. The validation analysis showed that the accuracy of the identification of the 10 batches of samples was as high as 100.0%. Therefore, based on UHPLC-QTOF-MS~E and Adaboost algorithm, the digital identification of Cervi Cornu Pantotrichum can be realized efficiently and accurately, which can provide reference for the quality control and original animal identification of Cervi Cornu Pantotrichum.

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.

The effects of antlers have long been known in traditional Asian medicine. However, few studies have investigated the effects of antlers on immunity. In this study, we investigated whether fermented antler extract (FAE) has immunomodulatory effects on spleen cells. FAE enhanced the activity of spleen cells in a concentration dependent manner compared to antler extract. Interestingly, FAE significantly increased the production of interleukin-12, a representative cytokine of cell-mediated immunity, while it marginally increased that of tumor necrosis factor-alpha. Flow cytometry analysis demonstrated that FAE can protect spleen cells from spontaneous cell death without a significant proportional change in subsets, mainly lymphocytes. Taken together, the results of the present study showed that FAE has beneficial effects on spleen cells, a major type of immune cell, indicating that it can function as an immunomodulator without significant cytotoxicity. These data may broaden the use of FAE in basic research and clinical areas.

Podostroma cornu-damae is a rare, deadly fungus. However, it can be easily mistaken for antler Ganoderma lucidum. In this case report, two patients made tea with the fungus and drank it over a 2-week period. Both patients presented with bicytopenia, and one patient had desquamation of the palms and soles. Both were treated with prophylactic antibiotics and granulocyte colony-stimulating factor. One patient was admitted to the intensive care unit and received a platelet transfusion. Both patients were discharged without complications. Podostroma cornu-damae infections caused by intoxication were successfully treated using our treatment strategy, which consisted of prophylactic antibiotics, platelet transfusion, and granulocyte colony-stimulating factor. We believe this report can guide future treatment.

High resolution melting (HRM) , an important technology for genotyping and mutation scanning, has broad prospects in the authenticity of traditional Chinese medicine. This paper selected universal CO I primers and used HRM to establish a new method for authenticity of Hairy Antler. PCR was conducted at the annealing temperature of 60 °C and 45 cycles. The range of the DNA template concentration, the primer concentration and the Mg2+ ion concentration were further optimized. The results showed that the Tm values of Cervus nippon were (81.96 ± 0.07), (84.51 ± 0.03) °C and Cervus elaphus was(82.58 ± 0.13), (85.95 ± 0.05) °C with 10-100 mg · L(-1) DNA template, 0.2 µLmol · L(-1) primer, 2.0 mmol · L(-1) Mg2+. This method can authenticate of hairy antler and is simple, fast, high-throughput, visualization.

BACKGROUND/OBJECTIVES: We examined the chemical composition and the effect of fermented deer antler on hematopoietic factors in bone marrow cells. MATERIALS/METHODS: For the preparation of fermented deer antler extract (FAB), fermentation was carried out using Bacillus subtilis at 30degrees C for 7 days. The hematopoietic effect of FAB was investigated hematopoietic factors in marrow cells. RESULTS: The contents of total sugar, sulfated glycosaminoglycans, and uronic acid and the dry weight gradually increased with fermentation time. The sialic acid content (from 0.14 mg/mL to 0.54 mg/mL) was the highest on the 4th day of fermentation after which it decreased. The proliferating activity of bone marrow cells increased with fermentation times. The levels of various hematopoietic growth factors were determined to verify the beneficial effect of deer antler extract fermented by B. subtilis on hematopoiesis. FAB increased the number of stem cell factors and granulocyte colony-stimulating factor in bone marrow cells. In addition, FAB augmented the burst-forming unit erythroid and total colonies in splenocyte-conditioned medium compared with non-fermented antler extract (NFA). However, FAB did not affect the mRNA levels of erythropoietin, an important factor for erythropoiesis. CONCLUSIONS: FAB, like NFA, did not directly affect hematopoiesis, but contributed to hematopoiesis by stimulating the production of hematopoietic factors.
