Objective:To evaluate the protective immunity by vaccination of BALB/c mice with rLV-HA-GCN4,a recombinant lentivirus expressing the trimeric HA of swine H1N1 influenza virus. Methods:The female mice were randomly divided into rLV-HA-GCN4,rLV-HA,LV and PBS groups. Mice were primed with plasmid and boosted with lentivirus by the administration of intramuscular thigh injections at an interval of two weeks. At day 28 post-prime immunization,mice were inoculated intranasally with 100TCID50 of swine H1N1 influenza virus in a 50 μl volume. The immune levels were assessed by the T lymphocyte transformation test, flow cytometry,indirect ELISA and the indexes of spleen and lung. Results:The spleen lymphocyte transformation rate was 0. 3±0. 11 in the rLV-HA-GCN4 group at day 14 post-boost immunization, showing a statistical significance ( P<0. 01 ) compared to the PBS group. Meanwhile,rLV-HA-GCN4 could cause T lymphocyte response mainly based on the Th1-type CD4+ T cells. The IgG antibody titer reached to 1:8 000 at day 14 post-boost immunization and approximately 1:7 000 at day 14 post challenge. After challenge,the spleen and lung indexes of rLV-HA-GCN4 group were significantly lower than those of PBS group (P<0. 05). The body weight of rLV-HA-GCN4 group demonstrated a slight decrease before 3 days post challenge and then a gradual increase compared to the LV and PBS groups (P<0. 05). Conclusion:rLV-HA-GCN4 can effectively induce cellular and humoral immune response in BALB/c mice against swine H1N1 influenza virus.

Through consulting the ancient materia medica and medical books, combined with modern literature, this paper made a textual research on the name, origin, producing area, harvesting time and processing method of Piperis Kadsurae Caulis, in order to provide basis for the development of the famous classical formulas containing this herb. According to textual research, it is shown that the earliest name for Piperis Kadsurae Caulis as medicine was Nanteng in Bencao Shiyi, and there were other names such as Dinggongteng and Shinanteng in the ancient materia medica. The name of Haifengteng should appear in the Ming dynasty. Before the Song dynasty, the origin of Piperis Kadsurae Caulis was probably derived from caulis of Piper wallichii. After the Song dynasty, the main origins should be some species in Piper, such as P. kadsura and P. hancei, and its origin in the successive editions of Chinese Pharmacopoeia was only P. kadsura. Combining the original plant research, market survey and distribution of wild resources, it is suggested that the Haifengteng used in the famous classical formulas apart form the P. kadsura, the P. hancei should be add as original plant. Due to climate change and the heat-loving habit of Piper, the producing area of Haifengteng gradually moved from the Qinling Mountains to the southern areas rich in Piper, and Quanzhou area of Fujian province has been recommended since the Ming dynasty. The harvesting period of Piperis Kadsurae Caulis is from July to August in the lunar calendar, the above-ground parts are dried by removing fibrous roots, thin stems and leaves. In the past dynasties, there are few records on the processing of this herb, so it is suggested that Piperis Kadsurae Caulis in famous classical formulas without special processing requirements should be used as raw products.

In this paper, the name, origin, producing area, harvesting, processing and functional indications of Arcae Concha were systematically combed and verified by consulting the ancient and modern literature, in order to provide a basis for the development of famous classical formulas containing Arcae Concha. Arcae Concha was first recorded in the name of Han in Bencao Shiyi, but later, due to the influence of LI Shizhen's error of combining Han item with Kuiha in the Ming dynasty, there were aliases such as Kuilu and Fulao, and Yizong Bidu began to include Walengzi as its correct name and has been used ever since. The textual descriptions and illustrations of the medicinal materials of Arcae Concha contained in the materia medica of the past generations were consistent with the modern Arca inflata, A. subcrenata and A. granosa. In ancient times, there were medicinal records of two parts of shell and meat, but now the shell is used as medicine, and the meat is mostly edible. In ancient times, Zhejiang, Shandong, Guangdong and Guangxi were the main producing areas, and Zhejiang was the best. It is now believed that A. inflata is mostly distributed in the northern part of the Huanghai Sea, A. granosa is mostly distributed in the coastal areas south of Shandong Peninsula in China, and A. subcrenata is widely distributed in the coastal areas of China. Its quality is better in a complete, white, no residual meat and sand. In ancient times, there was no clear harvesting period, and the processing was mainly based on vinegar quenching after calcination or powdering of calcined shell, but now the harvesting period is autumn and winter. After harvesting, it is directly washed and crushed for raw use or processed by calcined method. The records of the medicinal materials in the past dynasties on the properties of Arcae Concha were mainly warm, sweet, salty and mild, and it is now believed that Arcae Concha is salty in taste and mild in nature. In ancient times, it was believed that Arcae Concha were mainly used for coldness in the heart and abdomen, coldness in the waist and spine, benefiting the five internal organs, strengthening the stomach. Nowadays, it is believed that Arcae Concha can eliminate phlegm and remove blood stasis, soften the hardness and dissipate the lumps, produce acid and relieve pain. It can be used in the treatment of stubborn phlegm, gall tumor, scrofula and other symptoms. In conclusion, it is suggested that for the famous classical formulas containing Arcae Concha, the corresponding methods should be selected according to the processing requirements of the drug in the formulas, while those without processing requirements can be determined according to the functional position of the products.

By reviewing the ancient materia medica, medical books and modern literature, this paper made a systematic textual research on Haliotidis Concha in famous classical formulas, including the name, origin, producing area, quality evaluation, harvesting and processing, in order to provide a basis for the development of famous classical formulas containing Haliotidis Concha. The textual research showed that Shijueming was the official name of Haliotidis Concha in past dynasties, and there were also aliases such as Qianliguang, Jiukongluo and Zhenzhumu named after its efficacy, properties and near-phonetic characters. Before the Tang dynasty, the original description of Haliotidis Concha was too concise, which could only be identified as the animal of genus Haliotis, family Haliotidae. During the Song, Yuan, Ming and Qing dynasties, the main varieties were H. diversicolor and H. discus hannai. At the beginning of the Republic of China, a variety of animals from genus Haliotis were used as Haliotidis Concha, and varieties were numerous and continued to this day. In ancient and modern times, the main producing areas in China are Hainan, Guangdong and Shandong, while the foreign producing areas are mainly Japan and Vietnam. The quality evaluation of Haliotidis Concha in ancient books was roughly determined by the number of openings of the expiratory orifice, and seven-hole and nine-hole abalone shells were preferred. In modern times, characters as big, neat, unbroken, clean inside and outside, lustrous, thick shells are preferred. Based on the textual research results and combined with the record years of the Shijueming San, it is suggested that the shells of H. diversicolor or H. discus hannai should be used in the development of this formula, and the raw products should be used as medicine.

Through consulting the ancient herbal books and modern literature, this paper has carried out the textual research on the name, origin, place of origin, harvesting and processing, and other contents of Bruceae Fructus, combed its ancient and modern medicinal history, so as to provide reference for the development of famous classical formulas containing Bruceae Fructus. Through the herbal textual research, It can be verified that, since the Qing dynasty, Bruceae Fructus has been recorded in the materia medica, most of the materia medica in previous dynasties took Bruceae Fructus as its proper name, and Laoyadan, Kushenzi and Yadanzi as the aliases. The main origin of Bruceae Fructus is Brucea javanica, its medicinal part is the fruit, which is harvested from August to October every year, the fruit can be harvested when it is ripe. Bruceae Fructus was first distributed in Fujian, Guangdong and Guangxi, and gradually expanded to the south of China with the change of time. The traditional processing method of Bruceae Fructus is mainly to remove the shell and kernel, and remove the oil by frosting. The 2020 edition of Chinese Pharmacopoeia stipulates that its processing method is to remove the shell and impurities. Based on the research results, it is suggested that the dried mature fruit of B. javanica should be selected for the development of famous classical formulas containing this herb, and the raw products can be used if the original formula does not specify the processing requirements.
