4. Pharmacognosy Identification of Hippocampus barbouri Based on the Combination of the Morphological Characteristics and DNA Barcodes
Chinese Pharmaceutical Journal 2019;54(24):2047-2054
OBJECTIVE: To obtain the key identification information of Hippocampus barbouri (H. barbouri), investigate the pharmacognosy of the seahorse adulteration H. barbouri, using the combination of morphological and DNA barcoding technique. METHODS: Typical morphological characteristics of H. barbouri were studied based on the observations according to the previous reports and traditional pharmacognosy methods. Genomic DNAs of H. barbouri and other related seahorse species were extracted and the DNA barcoding genes of COI, 16S and ATP6 sequences were amplified and sequenced, respectively. In order to determine advantages of three barcodes for the identification of hippocampus, MEGA 7 was performed to analyze the intraspecific and interspecific distances and construct the NJ phylogenetic trees based on three different barcoding genes. RESULTS: The most typical distinguishing features of H. barbouri included the streak of the nose, five radial lines in the eyelid, and the long and short intervals of the tail thorns. The lengths of COI, 16S and ATP6 sequences were 649-650, 574 and 603 bp, respectively, with the maximum K2P intraspecific distances were 0.012, 0.003 and 0.003, respectively. The intraspecific distances of the three barcodes were far smaller than the corresponding minimum K2P interspecific distances of H. barbouri and other seven related seahorse species, existing an obvious barcoding gap. The NJ phylogenetic trees based on COI, 16S and ATP6 sequences showed that H. barbouri samples formed of a group indicating that H. barbouri could be distinguished from other seahorse species through the three DNA barcoding markers. In addition, H. barbouri showed close genetic relationship with H. histrix according to the NJ trees. Furthermore, the NJ tree structures of COI and ATP6 were more stable than that of 16S. CONCLUSION: The pharmacognostical investigation bases on the morphological identification and DNA barcodes obtained the key identification information of H. barbouri, providing the possibility for quick and accurate identification of this species. The COI, 16S and ATP6 barcoding genes can be used for further molecular identification markers for seahorse species. This study provides a new technical method for the development and quality control of hippocampus.

OBJECTIVETo observe the primary prevention role of Wuling Capsule (WC) on poststroke depression (PSD) patients.
METHODSAcute stroke patients were recruited and randomized into 2 groups by stratification, 55 in each group. All patients received same routine treatment of cardiovascular diseases. Patients in the experimental group additionally took WC (0.33 g each pill), 3 pills per day, three times per day; while those in the control group additionally took placebos, 3 pills per day, three times per day. Two weeks consisted of one therapeutic course. The diagnosis of PSD was performed once every other week. Those in accordance with PSD diagnosis discontinued any drug therapy. Those not in accordance with PSD diagnosis continued the drug therapy for 1-12 therapeutic course(s) (in total of 6 months). If they were still not in accordance with PSD diagnosis, then they discontinued the drug therapy. The morbidity of PSD, the average time of depression occurrence, Hamilton depression rating scale (HAMD) score, and adverse reactions were observed.
RESULTSThe 1-, 3-, and 6-month morbidity of PSD was 8%, 16%, and 34% in the experimental group, while they were 19.6%, 29.4%, and 54.9% in the control group. The occurrence rate was lower in the experimental group than in the control group. Besides, there was statistical difference in the 6-month occurrence rate between the two groups (chi2 = 4.465, P < 0.05). The average time of PSD occurrence was longer in the experimental group than in the control group (14.96 +/- 8.31 weeks vs. 9.36 +/- 6.06 weeks; t=6.762, P < 0.05). The HAMD score at the PSD occurrence was 11.96 +/- 2.14 in the experimental group, lower than that of the control group (14.57 +/- 4.24), showing statistical difference (t=5.641, P < 0.05).
CONCLUSIONWC was superior to the placebos in lowering the incidence of PSD, delaying the occurrence time of PSD, attenuating the depression degree of PSD, and had certain preventive effect on the incidence of PSD.

This study provides the candidate sequences in the identification of Radix et Rhizoma Clematidis and its adulterants using DNA barcoding. We amplified and sequenced the region psbA-trnH, with the data of 284 sequences from GenBank, the differential intra- and inter-specific divergences, genetic distance, barcoding gap were used to evaluate five barcodes, and the identification efficiency was assessed using BLAST1 and Nearest Distance methods. The results showed that psbA-trnH barcodes performed high identification efficiency and inter-specific divergences among the five different DNA barcodes. Analysis of the barcoding gap and NJ tree showed psbA-trnH was superior to other barcodes. Based on the identification and PCR amplification efficiency, psbA-trnH can be the ideal barcode to identify Radix et Rhizoma Clematidis and its adulterants accurately.

The marine biological source of mineral drugs recorded in Chinese Pharmacopoeia (2010 version) mainly including pearl, nacre, clam shell, common oyster shell, ark shell, cuttle bone, and sea-ear shell are widely used in clinical. Calcium carbonate and a small amount of protein are the main components in this type of drugs. In this paper, a systematical and comparable study were carried out by determination of calcium carbonate by EDTA titration method, the crystal of calcium carbonate by X-Ray powder diffraction and the total amino acids (TAAs) of the hydrolyzed samples by ultraviolet spectrophotometry method. As a result, the crystal structure is calcite for common oyster shell, mixture of calcite and aragonite for nacre and sea-ear shell, aragonite for the other drugs. The content of calcium carbonate ranged from 86% to 96%. Cuttle bone has the highest amount of TAAs among the seven drugs which reached 1.7% while clam shell has the lowest content of 0.16% on average. In conclusion, an effective method was developed for the quality control of marine mineral drugs by comprehensive analysis of calcium carbonate and TAAs in the seven marine mineral drugs.
