2. Evaluation of new ischemic brain damage after using protective filter device during carotid artery stenting with diffusion-weighted magnetic resonance imaging
Chinese Journal of Cerebrovascular Diseases 2011;8(3):130-133
Objective: To evaluate new ischemic brain damage after using protective filter device during carotid artery stenting with diffusion-weighted magnetic resonance imaging (DWI). Methods: A total of 60 patients with carotid stenosis (stenotic rate 50%-95%) were included in this study. They underwent carotid artery stenting and were divided into protective filter device group (n = 30) and none protective filter device group (n = 30). DWI was performed within 24 hours before and after the procedure. The number, size, and location of new cerebral ischemic lesions after the procedure were counted. Results: Circled digit oneDWI was performed within 24 hours after the procedure. A total of 18 patients occurred high-density ischemic cerebral lesions, six of them (20%) were in the protective filter device group and 12 (40%) were in the none protective filter device group. There was no significant difference (P >0.05). Circled digit two A total of 41 new ischemic cerebral lesions were detected, 14 of them were in the protective filter device group and 27 were in the none protective filter device group. The lesions mainly located in the same sides of stents. There was no significant difference in the constituent ratio of the lesion sites between two groups (P > 0.05). Circled digit threeThere were 33 lesions of ≤3 mm diameter, 13 of them were in the protective filter device group and 20 were in the none protective filter device group. There were 8 lesions >3 mm in diameter, one of them was in the protective filter device group and 7 were in the none protective filter device group. There was no significant difference in the constituent ratio of the lesion size between the two groups (P >0.05). Conclusion: Using protective filter device during carotid artery stenting may decrease the occurrence of new ischemic cerebral lesions, especially large large sized lesions. However, new ischemic cerebral lesions may occur during the procedure.

Chinese Traditional and Herbal Drugs 2020;51(23):5963-5971
Objective: To study the scientific connotation "carbonizing retains characteristics" of Platycladi Cacumen (PC). Methods: Chemical constituents of PC and Platycladi Cacumen Carbonisata (PCC) of different carbonizing degree were compared by HPLC characteristic chromatogram, and the chromatographic peaks were assigned; PC and PCC of different carbonizing degree and the characteristic components changed before and after being carbonized were used to compare the impact to hemostasis in vitro and inhibition of zebrafish cerebral hemorrhage. Results: Chemical compositions of PC were affected by different carbonizing degree, when carbonizing degree is moderate, the content of myricitrin, quercitroside, isoquercitroside, amentoflavone and hinokiflavone original in PC were significantly reduced and the amount of quercetin and kaempferol which were newly produced were higher. In vitro hemostatic experiments showed that compared with the blank group, the APTT and FIB of PC which was carbonized moderately were significantly different (P < 0.01) and TT was significantly different (P < 0.05). It also had obvious inhibition effect on zebrafish cerebral hemorrhage when the concentration of PC carbonized moderately was 50 μg/mL (P < 0.01). The enhanced hemostasis was significantly related to newly produced compositions quercetin and kaempferol. Conclusion: Chemical compositions of PC changed significantly after being carbonized and the hemostatic effect was enhanced,which were related to the processing degree. The scientific connotation and traditional processing requirements of "carbonizing retains characteristics" was preliminarily analyzed when the carbon medicine was processed by this study, which provides a certain idea for the research on traditional processing theory of carbon medicine.

The main problems and solutions of mineral drugs in clinical use were studied based on the investigation on the quality of Haematitum and Fluoritum pieces in venalicium. The outward appearance and intrinsic quality of Haematitum and Fluoritum pieces in venalicium were studied by the requires which were in the first part of Chinese Pharmacopoeia published in 2010. The outward appearance and intrinsic quality of mineral drugs had large differences, the disqualification rate was 41.67% in 12 batches of Haematitum pieces and the disqualification rate was 53.85% in 13 batches of Fluoritum pieces. The crushing granularity of mineral drugs should be defined, the quality standards should be further improved. The drug adiministration ought to strengthen inspection and supervision in order to ensure the stability and reliability of the clinical efficacy.

OBJECTIVETo identify the Cynomorii Herba and its analogues species using DNA barcoding technique.
METHODTotal genomic DNA extracted from all materials using the DNA extraction kit. The internal transcribed spacer 2 (ITS2) regions were amplified using polymerase chain reaction (PCR), and purified PCR products were sequenced bi-directionally. Sequence assembly and consensus sequence generation were performed using the CodonCode Aligner 3.7.1. The Kimura 2-Parameter (K2P) distances and GC content were computed using MEGA 5. 0. Species identification analyses were conducted through the species identification system for traditional Chinese medicine and neighbor-joining (NJ) trees.
RESULTThe ITS2 sequence lengths of Cynomorii Herba were 229 bp. The average intra-specific genetic distances of Cynomorii Herba were 0.003. The average inter-specific genetic distances between Cynomorii Herba and its adulterants species were 0.760. The results showed that the minimum inter-specific divergence is larger than the maximum intra-specific divergence. The species identification system for traditional Chinese medicine and NJ trees results indicated that Cynomorii Herba and its adulterants species can be easily identification.
CONCLUSIONThe ITS2 region is an efficient barcode for identification of Cynomorii Herba, which provide a new technique to ensure clinical safety in utilization of traditional Chinese medicine.

OBJECTIVETo evaluate the curative effect of Danxiaoling Pill (DXLP), a Chinese herbal preparation, in treating intrahepatic cholestasis in pregnancy (ICP).
METHODSFifty-eight cases of ICP were divided randomly into two groups and treated by DXLP and Composite Yiganling as control respectively with the other identical conventional treatment. The changes of clinical symptoms, related laboratory parameters after treatment and the condition of labor were observed.
RESULTSThe total effective rate in both groups was 100%, but the markedly effective rate in the DXLP treated group was higher than that in control group (P < 0.01). Levels of blood cholyglycine acid (CGA), alanine transaminase (ALT), aspartate transaminase (AST), total bilirubin, total cholesterol and low density lipoprotein were all decreased in both groups after treatment, but DXL showed a better efficacy in decreasing CGA, ALT and AST than that of Yiganling. Moreover, the amniotic fluid meconium contaminated rate, premature delivery occurrence in the DXLP group were lower than those in the control group, while the weight of newborn baby was higher in the former than in the latter.
CONCLUSIONDXLP could effectively lower the serum bile acid and improve liver function in treating ICP.
