ABSTRACT
@#To investigate the freshness, high molecular weight substances, the determination of polypeptide, haemolysis and agglomeration, biological activity of Cervus and Cucumis polypeptide injection; to provide the direction for improving the quality of products for enterprises; furthermore, to provide reference for the revision of the quality standards of Cervus and Cucumis polypeptide injection. Firstly, we investigated the factors affecting the freshness of the injection, including biogenic amines, aflatoxins, the acid value and peroxide value of the melon seeds. The method of dansyl chloride pre-column derivatization-HPLC was used to determine the content of 8 biogenic amines in Cervus and Cucumis polypeptide injection. The method validation results showed good specificity, precision, linearity and recovery rates, which was suitable for the determination of biogenic amines in Cervus and Cucumis polypeptide injection. The results of sample determination showed that relatively higher concentrations of cadaverine were detected in the products from company B. The results of aflatoxins, acid value and peroxide value showed that the melon seeds from some companies had rancidity, mildew and other problems, indicating that the quality standards of multi-component biochemical drugs containing animal- and plant-derived components should be controlled in terms of freshness. Secondly, the methods for the determination of high molecular weight substances and polypeptides in the quality standard were improved. Tricine-SDS-PAGE electrophoresis was used instead of gel chromatography to determine the high molecular weight substances, which improved the accuracy of determination. The kits were used instead of folin-phenol for the determination of peptide content, which is easy to operate, specific and suitable for high-throughput sample determination. Finally, the haemolysis, agglomeration, and biological activity of Cervus and Cucumis polypeptide injection were studied. The results showed that no haemolysis and agglomeration were found in all samples, and the inhibitory effect of samples on THP-1 proliferation in vitro from different companies was different to some extent. In conclusion, the optimized quality standard is more suitable for the detection of Cervus and Cucumis polypeptide injection, and can lay the foundation for improving the safety of multi-component biochemical drugs.
ABSTRACT
Two new polypeptides were isolated and purified from the extract of deer bone (constitutive part of Cucumis and Cervus polypeptide injection) by various column chromatography including C₄ 300Å and Sephadex G-50, as well as semipreparative HPLC. Their N-terminal amino acid sequences were identified by De Novo sequencing on the basis of MALDI-TOF-MS data and Explorer™ software. The N-terminal amino acid sequences of polypeptides were identified as NH₂-Gly-Pro-Val-Gly-Pro-Thr-Gly-Pro-Val-Gly-Ala-Ala-Gly-Pro-Ser-Gly-Pro-Asp (Mei18 peptide, 1) and NH₂-Ala-Gly-Pro-Ala-Gly-Pro-Leu-Gly-Pro-Leu-Gly-Pro-Leu-Gly-Pro-Leu-Gly-Pro-Pro-Asp-Ser-Try-Asp (Mei23 peptide, 2), respectively. Mei18 and Mei 23 peptides are new polypeptides.
ABSTRACT
@#The cervus and cucumis polypeptide is widely used in clinical practice, mainly for arthritis, ankylosing spondylitis, various types of fractures, lumbocrural pain and other diseases. Reports of Kounis syndrome (anaphylaxis associated acute myocardial ischemia syndrome) caused by cervus and cucumis polypeptide are rare. In this paper, cervus and cucumis polypeptide was applied for osteoarthritis of the patient with no history of coronary heart disease. Kounis syndrome appeared after intravenous drip for one minute. The patient was cured and discharged after treatment with antianaphylaxis and acute myocardial ischemia. As a common clinical drug, the cervus and cucumis polypeptide should be alert to the possibility of Kounis syndrome if acute myocardial ischemia occurs.
ABSTRACT
To analyze the clinical drug use characteristics and medication rules of cervus and cucumis polypeptide injection (CCP injection) for the patients with lumbar vertebra diseases. Based on the electronic medical data of 6 990 patients with CCP injection for lumbar vertebra diseases from 25 first-class hospitals over the whole country from 2004, statistical analysis was conducted for their general information, diagnostic information, orders information, laboratory test information and treatment results. The results showed that the age distribution was highest in patients aged 45 to 64 (3 883, 55.55%); protrusion of lumbar intervertebral disc was most common among lumbar vertebra diseases (5 519, 82.50%); and TCM syndrome mainly included hemostasis. The daily dose was most between 8-12 mL, with a usual treatment course of 1-3 d. Commonly used western medicines in combined drug use included hypertonic dehydrating agent, antibiotics and nutrition nerve medicines, and the commonly used traditional Chinese medicines in combined drug use included the drugs with promoting blood circulation to remove blood stasis, kidney-tonifying and bone-building agents, and formula for clearing heat and removing toxicity, etc. The most commonly used western medicines are methylamine, adenosine, lidocaine injection, mannitol, et al, and the most commonly used Chinese medicines included Jintiange capsules, Qianggu capsules, et al. It is suggested that CCP injection for lumbar vertebrae diseases is mainly used in middle-aged and elderly patients, and is frequently used in combination with kidney-tonifying and bone-building agents, drugs with promoting blood circulation to remove blood stasis, analgesic agents and antibiotics.
ABSTRACT
This paper was aimed to understand the clinical features of traditional Chinese medicine (TCM) through the analysis of relevant information among fracture patients treated by the Cervus and Cucumis Polypeptide Injection (CCPI).The study was conducted among fracture patients treated by CCPI in the hospital information systems (HIS) among 26 national triple-A hospitals from 2003 to 2014.The general information,TCM syndrome and solar term of morbidity were analyzed.The results showed that the number of patients from 45-64 years old were the most,accounting for 39.84％.Among them,the number of male patients from 18-44 years old was the most,accounting for 43.38％;the number of female patients from 45-64 year old was the most,accounting for 44.33％.The main TCM syndrome of admission and discharge was qi stagnation and blood stasis,which accounted for 60.53％ and 53.08％,respectively.Beginning of Summer (7th solar term) and Rain Water (2nd solar term) were solar terms with the most patients,which accounted for 5.26％ and 5.24％,respectively.It was concluded that the majority of fractures patients treated with CCPI were the elderly.The syndrome of qi stagnation and blood stasis was the most.The hospital admission of most patients was at the Beginning of Summer and Rain Water.It provided theoretical basis to pay attention on TCM syndrome differentiation in the treatment of clinical fractures.The treatment should be adapted to the characteristics of the disease itself,the change of solar terms,and dialectical medication.

ABSTRACT
[Objective]To study whether Cervus and Cucumis Polypeptide(CCP ,Lugua polypeptide) can treat osteoporosis or not. [Methods]Forty 4-month-old female SD rats were randomized into four groups(10 in each group) ,including SHAM,0VX, OVX+CCP1 and OVX+CCP2 groups. Male rats in OVX groups take the ovariectomized surgery. Since the 13th week, rats in groups A and B got 0.9% physiological saline injection once in a day, group C was treated with CCP 0.4mL/(kg·d)injection and group D treated with CCP0.8mL/(kg·d) injection once one day. Twelve weeks later, al rats were sacrificed for obtaining specimen. Took right femurs, measured the bone biomechanical properties. [Results ]After 12 weeks since injection, the biomechanical property of right femurs in group OVX was significantly lower than that of the SHAM group( P<0.01); parameters such as maximum load and elastic load in group OVX+CCP1 and OVX+CCP2 were higher than that of group OVX(P<0.05), but lower than that of group SHAM(P<0.05). The distinction of the above parameters was significant( P<0.05)between group OVX+CCP1 and OVX+CCP2. [Conclusion]1.CCP can significantly im-prove the bone internal biomechanical properties in ovariectomized(OVX) rats, so it has function to treat osteoporosis caused by drop in estrogen level. There are differences of bone biomechanical properties aspects when treated with different dosage of CCP, which shows the tendency of dose-dependent effect. So we can conclude that CCP may have dose-dependent effect.
