Heparin-binding hemagglutinin as a composition antigen of tuberculosis vaccine exerts protective immune effects by inducing IL-17 / 中华预防医学杂志

To explore the protective immune effect induced by mucosal delivery heparin-binding hemagglutinin (HBHA)-a candidate vaccine antigen of Mycobacterium tuberculosis. Female C57BL/6 mice were between 6 and 8 weeks of age before experimental use. Thirty mice received different immunization strategies and were randomly divided into the control group, the early secreting antigen target-6 (ESAT-6) intranasal immunization group, the HBHA intranasal immunization group, the BCG priming PBS control group, or BCG priming HBHA boost group, 6 mice in each group. In order to analyzed the immune effect, the concentrations of plasma Interleukin-17A (IL-17A) and other cytokines were measured by ELISA. Quantitative real-time PCR analyses were performed to detect the relative quantity (RQ) mRNA of IL-17A in the lung. The lung tissue sections were stained to detect the formation of the tertiary lymphoid structures. The chemokines contributed to formation of the tertiary lymphoid structures were also measured. Flow cytometry was used to detect the frequency of Th1 and Th17 cells in the system. Sixty mice in the BCG priming PBS control group and the BCG priming HBHA boost group were sacrificed at different time points after infection to count the lung bacterial burden. The concentrations of plasma IL-17A and relative quantity of lung IL-17A mRNA were highest in the BCG priming HBHA boost group [(14.76±4.73) pg/mL,RQ (12.27±6.71)], which was significantly higher than the control group [(5.57±2.95) pg/mL,RQ (1.30±0.97)] (t=4.213, P<0.001; t=5.984, P<0.001), and also significantly higher than the BCG priming PBS control group [(6.81±2.18) pg/mL,RQ (1.44±1.16)] (t=3.646 P=0.001; t=6.185 P<0.001). Compared with the BCG priming PBS control group (0.38±0.38)% the frequency of spleen Th17 cells were also significantly increased (t=-0.280 , P=0.048) in the BCG-primary HBHA boost group (1.02±0.34)%. In addition, HBHA boosting could promote better formation of the tertiary lymphoid structures in the lung, and decrease the bacterial load on the early stage after BCG challenge. Collectively, mucosal delivery of HBHA can effectively enhance the protective effect after BCG vaccination, and it is a potential candidate vaccine component.

Study on intermittent fasting changing fecal metabolism pattern of mice based on metabolomics technique / 药学学报

Increasingly researches suggested that intermittent fasting (IF) can be part of a healthy lifestyle, which can improve risk factors associated with obesity and diabetes. Based on LC-MS metabolomics technology, this study preliminarily discussed the effect of IF on the metabolism of mice under normal physiological conditions by detecting the fecal metabolites. All experiments were approved by the Animal Research Committee of Shanghai University of Traditional Chinese Medicine. Animal welfare and the animal experimental protocols were strictly consistent with related ethics regulations of Shanghai University of Traditional Chinese Medicine. The mice were subjected to intermittent fasting for 10 weeks by fasting for 24 hours on alternate days, and their feces at 5 and 10 weeks were collected. The results show that the weight, food and water intake was not significant altered in mice with IF, but fasting blood glucose level was decreased. We found that fecal metabolites change was present at 5-week, being more prominent in 10-week. Relative to the control mice, we detected 17 and 108 metabolites in two time points, respectively. These metabolites were mainly enriched in the pathways of linoleic acid metabolism and bile acid biosynthesis. We further found that 10 metabolites may be a close correlation with IF, which had the same change trend at two time points. In conclusion, the present study provides a new approach to study the metabolism mechanism in IF treatment of related diseases.

Determination of six effective ingredients in Imperatae Rhizoma concentrated granules by ultra-performance liquid chromatography using two internal references / 药学学报

To simultaneously determine the contents of p-coumaric acid, chlorogenic acid, 5-caffeoylquinic acid, 4-caffeoylquinic acid, caffeic acid and ferulic acid in Imperatae Rhizoma concentrated granules, an ultra-high performance liquid chromatography (UPLC) with two internal references method (TIRM) was established and validated. Chromatographic separation was achieved on a ZORBAX RRHD Eclipse Plus C18 column (2.1 mm × 100 mm, 1.8 µm) using 1.7 mmol·L-1 oxalic acid in water and methanol as mobile phase. The flow rate was 0.4 mL·min-1 and the column temperature was set as 35 ℃. The relative correction factors (RCFs) of caffeic acid and ferulic acid using p-coumaric acid as internal reference were calculated and the RCFs of 4-caffeoylquinic acid and 5-caffeoylquinic acid were calculated using chlorogenic acid as the internal reference. The TIRM was fully validated for linearity, accuracy, repeatability, stability and recovery so that it could be compared with the external standard method (ESM). The RCFs of 5-caffeoylquinic acid, 4-caffeoylquinic acid, caffeic acid, and ferulic acid were 1.069, 1.022, 1.368, and 1.493, respectively. The TIRM and ESM were used to determine the contents of six ingredients in Imperatae Rhizoma concentrated granules from different manufacturers and the variation between results was within acceptable limits. In conclusion, the newly established TIRM allowed simultaneous determination of six ingredients (p-coumaric acid, chlorogenic acid, 5-caffeoylquinic acid, 4-caffeoylquinic acid, caffeic acid, ferulic acid) in Imperatae Rhizoma concentrated granules, providing support for the quality control of this traditional Chinese medicine.

Research progress of Curcuma kwangsiensis root tubers and analysis of liver protection and anti-tumor mechanisms based on Q-markers / 中国中药杂志

Curcuma kwangsiensis root tuber is a widely used genuine medicinal material in Guangxi, with the main active components of terpenoids and curcumins. It has the effects of promoting blood circulation to relieve pain, moving Qi to relieve depression, clearing heart and cooling blood, promoting gallbladder function and anti-icterus. Modern research has proved its functions in liver protection, anti-tumor, anti-oxidation, blood lipid reduction and immunosuppression. Considering the research progress of C. kwangsiensis root tubers and the core concept of quality marker(Q-marker), we predicted the Q-markers of C. kwangsiensis root tubers from plant phylogeny, chemical component specificity, traditional pharmacodynamic properties, new pharmacodynamic uses, chemical component measurability, processing methods, compatibility, and components migrating to blood. Curcumin, curcumol, curcumadiol, curcumenol, curdione, germacrone, and β-elemene may be the possible Q-markers. Based on the predicted Q-markers, the mechanisms of the liver-protecting and anti-tumor activities of C. kwangsiensis root tubers were analyzed. AKT1, IL6, EGFR, and STAT3 were identified as the key targets, and neuroactive ligand-receptor interaction signaling pathway, nitrogen metabolism pathway, cancer pathway, and hepatitis B pathway were the major involved pathways. This review provides a basis for the quality evaluation and product development of C. kwangsiensis root tubers and gives insights into the research on Chinese medicinal materials.

The clinical phenotype and gene analysis of syndromic deafness with PTPN11 gene mutation / 中华耳鼻咽喉头颈外科杂志

Objective: To analyze the clinical phenotype and screen the genetic mutations of hereditary deafness in three deaf families to clarify their molecular biology etiology. Methods: From January 2019 to January 2020, three deaf children and family members were collected for medical history, physical examination, audiology evaluation, electrocardiogram and cardiac color Doppler ultrasound, temporal bone CT examination, and peripheral blood DNA was obtained for high-throughput sequencing of deafness genes. Sanger sequencing was performed to verify the variant sites among family members. The pathogenicity of the variants was evaluated according to the American College of Medical Genetics and Genomics. Results: The probands in the three families had deafness phenotypes. In family 1, proband had multiple lentigines, special facial features, growth retardation, pectus carinatum, abnormal skin elasticity, cryptorchidism and other manifestations. In family 2, proband had special facial features, growth retardation and abnormal heart, and the proband in family 3 had growth retardation and abnormal electrocardiogram. Genetic testing of three families detected three heterozygous mutations in the PTPN11 gene: c.1391G>C (p.Gly464Ala), c.1510A>G (p.Met504Val), c.1502G>A (p.Arg501Lys). All three sites were missense mutations, and the mutation sites were highly conserved among multiple homologous species. Based on clinical manifestations and genetic test results, proband 1 was diagnosed with multiple lentigines Noonan syndrome, and probands 2 and 3 were diagnosed with Noonan syndrome. Conclusion: Missense mutations in the PTPN11 gene may be the cause of the disease in the three deaf families. This study enriches the clinical phenotype and mutation spectrum of the PTPN11 gene in the Chinese population.

Rapid hemostasis: a novel and effective outpatient procedure using microwave ablation to control epistaxis of isolated mucosal bulge lesions / Hemostasia rápida: um procedimento ambulatorial novo e eficaz utilizando ablação por micro-ondas para controlar a epistaxe de lesões isoladas protuberantes da mucosa

Abstract Introduction Recurrent epistaxis is commonly encountered in the rhinology outpatient clinic. Under endoscopic guidance, both bipolar cautery and monopolar forceps (combined with suction) have been employed to control the bleeding. However, the use of monopolar forceps requires the placement of grounding pads. Most procedures are currently performed in operating rooms. Objective We investigated outcomes after the use of Microwave Ablation (MWA) to control epistaxis in adults with isolated mucosal bulge lesions. All procedures were performed with patients under local anesthesia in our outpatient clinic. Methods This is a retrospective cohort study. We included 83 adults with epistaxis of isolated mucosal bulge lesions. Microwave ablation was performed in the outpatient clinic to control bleeding, after induction of local anesthesia. The primary outcome was successful hemostasis. The secondary outcomes were the rebleeding rates at weeks 1 and 4 and month 6, and complications (crust or synechiae formation, septal perforation, and/or orbit or brain complications). Results All bleeding points were successfully ablated; hemostasis was achieved within 1-2 min. The mean pain score was 1.83 intra-operatively and 0.95 1 h postoperatively. No patient re-bled, and no severe MWA-related complication (septal perforation, synechiae formation, or orbit or brain complication) was recorded to 6 months of follow-up. Conclusions Endoscopic microwave ablation with patients under local anesthesia is a novel, safe, effective, rapid, well-tolerated, outpatient treatment for adults with epistaxis of isolated mucosal bulge lesions, especially those for whom general anesthesia might be risky, those with electrical implants, and those exhibiting contraindications for arterial embolization.

Sob orientação endoscópica, foram empregados tanto o cautério bipolar quanto a pinça monopolar (combinados à sucção) para controlar a condição. No entanto, o uso de pinças monopolares requer a colocação de placas de aterramento. Atualmente, a maioria dos procedimentos é feita em salas de cirurgia. Objetivo Investigamos os resultados após o uso da ablação por micro-ondas (MWA, do inglês Microwave Ablation) no controle da epistaxe em adultos com lesões isoladas protuberantes da mucosa. Todos os procedimentos foram feitos em nosso ambulatório com os pacientes sob anestesia local. Métodos Estudo de coorte retrospectivo. Foram incluídos 83 adultos com epistaxe de lesões isoladas protuberantes da mucosa. A ablação por micro-ondas foi feita no ambulatório para controlar o sangramento, após a administração de anestesia local. O desfecho primário foi uma hemostasia bem-sucedida. Os desfechos secundários foram as taxas de ressangramento, nas semanas 1 e 4 e no mês 6, e complicações (formação de crostas ou sinéquias, perfuração septal e/ou complicações orbitais ou cerebrais). Resultados Todos os pontos de sangramento foram contidos com sucesso; a hemostasia foi alcançada em 1-2 minutos. O escore médio de dor foi de 1,83 no intraoperatório e de 0,95 1 h no pós-operatório. Nenhum paciente apresentou ressangramento e nenhuma complicação grave relacionada à MWA (perfuração septal, formação de sinéquias ou complicações orbitais ou cerebrais) foi registrada em 6 meses de seguimento. Conclusões A ablação endoscópica por micro-ondas com pacientes sob anestesia local é um tratamento ambulatorial novo, seguro, eficaz, rápido e bem tolerado para adultos com epistaxe de lesões isoladas protuberantes da mucosa, especialmente aqueles para os quais a anestesia geral pode ser arriscada, indivíduos com implantes elétricos e aqueles com contraindicações para embolização arterial.

Objective: To analyze the medication rules of traditional Chinese medicine (TCM) preventive oral prescriptions for COVID-19. Methods: The preventive oral prescriptions for COVID-19 published by national and provincial health and wellness committees, administrations of TCM, medical institutions at all levels, medical masters and Chinese medicine experts were collected to establish a database, manual screening was carried out according to the inclusion and exclusion criteria, and frequency statistics, association rule analysis. The mutual information method, entropy hierarchical clustering and other methods were improved through Excel and the TCM inheritance auxiliary platform V2.5 to mine the rules and characteristics of medication. Results: The selected 157 prescriptions contained a total of 130 TCMs. The top five TCMs with the highest use frequency were Glycyrrhizae Radix et Rhizoma (86), Astragali Radix (80), Lonicerea Japonicae Flos (70), Atractylodis Macrocephalae Rhizoma (62), Saposhnikoviae Radix (60). In accordance with TCM efficacy classification, most of them were medicines for qi-tonifying (279), followed by medicines for clearing heat and drying dampness (163), dispelling pathogenic wind-cold (126), resolving dampness (111), as well as dispelling pathogenic wind-heat (99). The characteristics of four-natures of the selected medicines are as follows: most of them were cold (59), followed by warm (38) and mild (21). In terms of five-taste, most of them were sweet (26) and acrid-and-bitter (24), followed by sweet-and-bitter (20), bitter (20) and acrid (15). For the meridian attribution, the five-zang organs and six-fu organs were all involved, most of them attributed to lung meridian (80), followed by stomach meridian (57) and spleen meridian (40). Based on association rule analysis, 12 commonly used medicine combinations with two or three TCMs were found. The commonly used medicinal pairs included Astragali Radix and Saposhnikoviae Radix (51), Astragali Radix and Atractylodis Macrocephalae Rhizoma (46), Atractylodis Macrocephalae Rhizoma and Saposhnikoviae Radix (43), Astragali Radix and Atractylodis Macrocephalae Rhizoma and Saposhnikoviae Radix (38), Forsythiae Fructus and Astragali Radix (37), and so on. In addition, 14 core combinations of medicines were obtained by complex system entropy cluster analysis, on this basis, six new prescriptions were screened out based on unsupervised entropy hierarchical clustering analysis. According to The Catalogue of Edible Traditional Chinese Medicinal Materials, Traditional Chinese Medicinal Materials for Health Food, and New Resources of Food published by National Health Commission of the People's Republic of China, there are 35 species belonging to the group of edible traditional Chinese medicinal materials, 20 species belonging to the group of new resources of food, 31 species belonging to the group of traditional Chinese medicinal materials for health food, 19.11% of the preventive oral prescriptions for COVID-19 were composed of the medicines belonging to the above three groups. Besides, there are 11 toxic species, and 24.84% of the preventive oral prescriptions for COVID-19 contained toxic TCMs. Conclusion: We found that invigorating qi and resolving dampness were the main treatment used to prevent for COVID-19, combined with the methods for strengthening vital energy and eliminating pathogenic factors. Most of the preventive oral prescriptions for COVID-19 were treated in lung, spleen and stomach meridians. In the process of selecting prescriptions and using TCMs to prevent for COVID-19, the safety of preventive medicines was also emphasized. And the theory of “Preventive Treatment of Disease” was embodied in these preventive oral prescriptions for COVID-19. For the prescriptions containing toxic TCMs, special attention should be paid to their safety in clinical application.

Traditional medicinal plants for arthropod-borne diseases of five countries in Lancang-Mekong region:a review / 中国中药杂志

Arthropod-borne diseases, such as malaria and dengue fever, have frequently beset five countries(Cambodia, Vietnam, Laos, Myanmar, and Thailand) in the tropical rainy Lancang-Mekong region, which pose a huge threat to social production and daily life. As a resort to such diseases, chemical drugs risk the resistance in plasmodium, non-availability for dengue virus, and pollution to the environment. Traditional medicinal plants have the multi-component, multi-target, and multi-pathway characteristics, which are of great potential in drug development. Exploring potential medicinals for arthropod-borne diseases from traditional medicinal plants has become a hot spot. This study summarized the epidemiological background of arthropod-borne diseases in the Lancang-Mekong region and screened effective herbs from the 350 medicinal plants recorded in CHINA-ASEAN Traditional Medicine. Based on CNKI, VIP, and PubMed, the plants for malaria and dengue fever and those for killing and repelling mosquitoes were respectively sorted out. Their pharmacological effects and mechanisms were reviewed and the material basis was analyzed. The result is expected to serve as a reference for efficient utilization of medicinal resources, development of effective and safe drugs for malaria and dengue fever, and the further cooperation between China and the other five countries in the Lancang-Mekong region.

Quality control of red ginseng based on the ratio of ginsenosides Ro/Re / 药学学报

Ginsenoside Ro decreased measures of inflammation, aging, oxidants and thrombus formation in a previous study. To measure ginsenoside Ro content in red ginseng from different years, an optimized extraction method was developed to determine ginsenoside Rg1, Re, Rb1 and Ro content by HPLC in 43 batches of red ginseng from different origins, growing years and manufacturers. The results indicate that the best extraction method was to ultrasonify a 1 g sample in 70% methanol for 50 min. The total running time of the optimized gradient was 50 min using a C18 core-shell column and was half the time described in the Chinese Pharmacopoeia, 2015 edition. The separation resolution of all of targeted compounds was greater than 1.6. The peak shape of ginsenoside Ro was optimal when the mobile phase consisted of acetonitrile and water with 0.1% phosphoric acid. The content of ginsenoside Ro was in the range of 0.11% to 0.43%, and the average content was 0.26%, which was higher than that of ginsenoside Rg1 and Re. The ratio of ginsenoside Ro and Re as a threshold could be used to discriminate red ginseng from different growing years; in addition, 100%, 94.4% and 46.6% of red ginseng from six, five and four years exceeded the threshold of 1.3. Our optimized analytical method for characterization of red ginseng is convenient and shortens the assay time.

Optimization of extraction technology of Guizhi Zhumian Capsule by orthogonal design and pharmacodynamics test / 中草药

Objective: To optimize the extraction technology of Guizhi Zhumian Capsules (GZC). Methods: Based on the analysis of the single factor experiment Results:, the orthogonal test method was adopted to study the three factors including the amount of water added, extraction time, and extraction frequency by taking the dry extract yield of the medicinal materials and transfer rate of geniposide as indicators to optimize the water extraction process of GZC. To optimize the alcohol precipitation process of GSC, these factors including the concentration of the medicinal materials, alcohol content, and time of alcohol precipitation were investigated. The extracts before and after alcohol precipitation were compared by improving sleep pharmacodynamics. Results: The best water extraction technology of GZC was decocted three times with 10 times of water, 0.5 h each time. The optimal alcohol precipitation process was to concentrate the filtrate of water extraction to 1 mL, which was equivalent to 1 g of the original medicinal materials, with 80% alcohol content and 12 h alcohol precipitation time. Compared with the negative control group, the water extract group of GZC could prolong the sleep time of pentobarbital sodium mice and increase the sleep rate of mice under the lower dose of pentobarbital sodium valve (P 0.05). Conclusion: The pharmaceutical efficacy of the extract before and after alcohol precipitation was different. In order not to affect the drug effect, the water extraction process was finally selected as the best extraction process.
