Evaluation and optimization of content determination method of Chrysanthemi Flos in Chinese Pharmacopoeia / 中国中药杂志

This study discovered that the resolution of 3,5-O-dicaffeoylquinic acid(isochlorogenic acid A) in the content determination method of Chrysanthemi Flos in Chinese Pharmacopoeia(ChP)(2020 edition) was poor, which affected accurate quantification. We tested the method in ChP with chromatographic columns of seven brands to clarify the problems in the existing method, optimized the chromatographic conditions by adjusting the mobile phase composition and elution ratio and replacing the chromatographic column packing, and carried out the reproducibility assay for the new method. The two methods were compared for the content determination results of Chrysanthemi Flos prepared from six different varieties. As evaluated by the resolution based on different chromatographic columns of seven brands, the existing method failed to separate isochlorogenic acid A and isochlorogenic acid D well. The peaks of the two components were not completely separated on three chromatographic columns, and isochlorogenic acid A and isochlorogenic acid D generated a co-effluent peak in the other four columns. Isochlorogenic acid A and isochlorogenic acid D could be completely separated under the optimized chromatographic conditions. The difference in the peak areas of isochlorogenic acid A+isochlorogenic acid D obtained by the optimized method and the method in ChP was not significant, with deviation less than 3.0%, which further proved that the result measured by the method in ChP was the co-effluent of isochlorogenic acid A and isochlorogenic acid D. The optimized method can ensure the accurate quantification of isochlorogenic acid A. The existing content determination method of Chrysanthemi Flos has the problem of poor resolution. It is recommended to revise the chromatographic conditions for the content determination method of Chrysanthemi Flos to improve the resolution of isochlorogenic acid A and ensure its accurate quantification.

[Recommendations on quality standards of Andrographis Herba and its processed slices in Chinese Pharmacopoeia (2020 edition)].

To improve and perfect the quality standards and propose recommendations for the revision of quality standards for Andrographis Herba and its processed slices in Chinese Pharmacopoeia(ChP)(2020 edition) based on the problems and limitations in ChP(2015 edition). TLC identification method with andrographolide and control herbs as references was established using silica gel G thin layer plate, with chloroform-methylbenzene-methanol(8∶1∶1) as developing solvent, and 10% sulfuric acid ethanol solution as colour-developing agent. This method has good reproducibility, strong specificity and high sensitivity. As compared with the original method in ChP 2015, this method has better development effect and clearer spots. Based on the previous research, a quantitative analysis of multi-components by single-marker(QAMS) method with andrographolide as the internal reference substance was developed to simultaneously determine the contents of 4 diterpene lactones: andrographolide(S), neoandrographolide(A), 14-deoxyandrographolide(B), and dehydroandrographolide(C). The relative correction factors of f_(A/S), f_(B/S), and f_(C/S) were determined as 1.12, 0.79, and 0.63, respectively. The relative retention time of t_(A/S), t_(B/S), and t_(C/S) was 1.95, 2.18, and 2.25, respectively. According to the content determination results in 46 batches of crude drugs and 38 batches of processed slices, it was stipulated that the total contents of 4 diterpene lactones should not be less than 1.5% and 1.2% in crude drugs and processed slices, respectively. As compared with the original method in ChP 2015, the present QAMS method could not only reduce the detection cost and improve the efficiency, but also can be used to evaluate the quality of Andrographis Herba and its processed slices more comprehensively and objectively. Diterpene lactones are generally recognized as the effective components in Andrographis Herba, and their contents in leaves were much higher than those in stems. However, almost all of the current commercial processed slices are processed from stems, so their quality is gene-rally poor and the efficacy is hard to be guaranteed. Therefore, the weight percentage of leaves should be added into the inspection items of the processed slices and it should not be less than 25%.

Correlation between Depressive Behavior and Expressions of S100β and Brain-derived Neurotrophic Factor in Hippocampus and Frontal Cortex of Rats / 中国医学科学院学报

To investigate the association between chronic unpredictable mild stress (CUMS)-induced depressive-like behavior in rats and expressions of brain-derived neurotrophic factor (BDNF) and S100β in the hippocampal and prefrontal cortex. Rats were randomly assigned to three groups:saline control group,saline+CUMS group,and citalopram +CUMS group. CUMS was used for depression modeling in rats. Depressive-like behavior in rats were evaluated by open-field test,sucrose preference test,and novel object recognition test. S100β and BDNF expressions were tested by enzyme-linked immunosorbent assay. Rats in the saline+CUMS group had significantly lower score in sucrose preference [(52.48±13.14)%],basic motor tasks [(845.8±371.4)s],fine motor tasks [(565.6±211.9)s],and longer resting time [(282.6±11.8)s] compared to the control group [(84.30±6.15)% (=7.49,=0.000),(1239.1±281.6)s (=2.83,=0.008),(801.8±150.9)s (=3.05,=0.003),(268.2±12.8)s (=2.72,=0.001)]. Compared with the citalopram+CUMS group,rats from the saline+CUMS group also showed significantly lower results in sucrose preference [(80.55±11.31)%,=5.39,=0.000],basic motor tasks [(1156.4±314.7)s,=2.13,=0.031],and fine motor tasks [(736.1±150.0)s,=2.21,=0.008]. There were no significant differences in the expression of hippocampal and prefrontal BDNF between these two groups,but rats from the saline+CUMS group expressed significantly higher levels of S100β compared to rats from the citalopram+CUMS group [(13.22±2.23) ng/g (10.55±2.72) ng/g,=2.67,=0.014]. Pearson correlation analysis revealed that the expression of S100β was positively correlated with the expression of BDNF in the prefrontal cortex and hippocampus (=0.35,=0.034;=0.36,=0.034).The novel object recognition index was positively correlated with the expression of BDNF in the hippocampus(=0.38,=0.021),and the duration of fine-motor activities was negatively correlated with S100β in the prefrontal cortex (=-0.36,=0.037). Different types of depressive behaviors in rats induced by CUMS are associated with the selective expression of S100β and BDNF in two different brain cortex. S100β protein and BDNF may independently participate in the pathogenesis of depression.

Objective To investigate the therapeutic effect of enteral nutrition in patients with severe traumatic brain injury (sTBI) by nasogastric tube and nasointestinal tube.Methods A retrospective case control study was made on 64 patients with sTBI hospitalized from October 2013 to December 2015.The patients were assigned to nasogastric tube group (n=32) and nasointestinal tube group (n=32) according to the random number table, and the same nutrient solution was given to all patients.Eighteen male and 14 female patients aged (37.8±8.7)years were identified in nasogastric tube group, and the Glasgow coma score (GCS) was (4.7±1.3)points.Twenty males and 14 females aged (39.7±6.5)years were identified in nasointestinal tube group, and the GCS was (4.1±1.2)points.Triceps skinfold thickness, body mass index, hemoglobin, level of serum albumin and level of prealbumin were measured and compared between groups before and after operation.Incidence of complications was recorded as well.Results All the above-mentioned indexes of the two groups did not differ significantly before the therapy (P>0.05), but showed significant differences 7 and 15 days after therapy (P<0.05).Incidence of complications in nasointestinal tube group (17 lung infection, nine gastrointestinal bleeding, 11 electrolyte imbalance) was lower than that in nasogastric tube group (seven lung infection, two gastrointestinal bleeding, one reflux esophagitis, four electrolyte imbalance) (P<0.05).Conclusion Nasointestinal tube enteral nutrition is better than nasogastric tube enteral nutrition in improving nutritional status and reducing complications in patients with sTBI.

Impact of sulfur fumigation on quality of Scutellariae Radix / 中国中药杂志

Sulfur fumigation usually causes transformation of chemical components of traditional Chinese medicine (TCM). As for the process and storage of TCM, the sulfur fumigation has been no longer recommended by the government. This study is to explore the impact of the sulfur fumigation on the quality of Scutellariae Radix. Distillation combined with ion-chromatography was used to evaluate the residue of sulfur dioxide in 180 batches of Scutellariae Radix decoction pieces and 26 batches of Scutellariae Radix herbs. In addition, LC-MS combined with principal component analysis (PCA) was used to compare the changes in chemical components and flavonoid content in radix scutellariae before and after sulfur fumigation. As a result, 74 batches of Scutellariae Radix decoction pieces were determined to be unqualified on the basis of the residue limit of sulfur dioxide in Chinese Pharmacopoeia 2015 Vol. Ⅳ (≤150 mg•kg⁻¹), with a qualification rate of 35.9%. All of the unqualified samples were decoction pieces. The fingerprint and PCA indicates that flavonoid content of Scutellariae Radix had no change before and after sulfur fumigation, but flavonoid glycosides decreased after sulfur fumigation and baicalin decreased sharply. The flavonoid glycoside was hydrolyzed to flavone aglycone in the process of sulfur fumigation, which caused the decrease in content of falvonoid glycosides and had an impact on the quality of Scutellariae Radix. The decoction pieces of Scutellariae Radix were seriously fumigated with sulfur in the processing, suggesting the key regulatory point is the decoction pieces production process.

Study of hypoxia-induced immune injury and its intervention measure / 中国应用生理学杂志

<p><b>OBJECTIVE</b>To explore the characteristic of hypoxia-induced immune injury, its mechanisms and the intervention measure.</p><p><b>METHODS</b>The change of immune organ index, T lymphocyte subsets of peripheral blood and immune organ in mice during hypoxia were detected. Lymphocyte apoptosis of immune organ, pathology of lung and kidney in mice were observed. Then by way of prophylaxis we studied the effect of Chinese Traditional Medicine on hypoxia-induced immune injury in mice.</p><p><b>RESULTS</b>(1) Exposure to hypoxia at 8 000 m simulated altitude for 8 h resulted in marked decrease in CD4+ CD8+ thymocytes and marked increase in CD4+ CD8-, CD4- CD8+ thymocytes (P < 0.01). After 3 days of hypoxia, the mice had a much lower percentage of CD4+ T-cell (P < 0.05). The ratio of CD4+/CD8+ decreased significantly and aforesaid changes of thymocyte were further enlarged. Also mice had a pronounced increase in rates of late apoptosis or necrosis of spleen lymphocyte and thymocyte (P < 0.05). After 6 days of hypoxia, index of spleen was significantly increased (P < 0.05), index of thymus was significantly decreased (P < 0.05) and CD3+, CD4+, CD8+ lymphocyte percentage of spleen were significantly decreased (P < 0.01). Also late apoptosis or necrosis lymphocytes of spleen and thymus were further increased (P < 0.01), viable cell rates of spleen lymphocyte and thymocytes were markedly decreased (P < 0.01), early apoptosis rates of spleen lymphocyte were markedly increased (P < 0.01). There was no significant change in the percentage of CD8+ lymphocyte in peripheral blood during the whole hypoxia period. (2) New Compound Codonopsis Pilosula (NCCP), Xiang Qi Polysaccharide (XQP) and NCCP + XQP could significantly increase the number of peripheral blood CD3+, CD4+ and spleen CD4+, but had no significant influence on the number of spleen CD8+. XQP and XQP+ NCCP could significantly decrease the number of CD4+ CD8+ (P < 0.01), increase that of CD4+ CD8- (P < 0.01), and had no significant influence on CD4- CD8+ in thymus. However, NCCP didn't influence the component of thymocytes.</p><p><b>CONCLUSION</b>After hypoxia at 8 000 m simulated altitude decrease of lymphocyte of periphery in mice may be related with increase of apoptosis and necrosis of lymphocyte, and with increase of distribution of lymphocyte to lung in early period of exposure. NCCP and XQP have hopeful prospect in intervention study of hypoxia-induced immune injury.</p>
