RESUMO

Puerariae Lobatae Radix, the dried root of Pueraria lobata, is a traditional Chinese medicine with a long history. Puerariae Lobatae Caulis as an adulterant is always mixed into Puerariae Lobatae Radix for sales in the market. This study employed hyperspectral imaging(HSI) to distinguish between the two products. VNIR lens(spectral scope of 410-990 nm) and SWIR lens(spectral scope of 950-2 500 nm) were used for image acquiring. Multi-layer perceptron(MLP), partial least squares discriminant analysis(PLS-DA), and support vector machine(SVM) were employed to establish the full-waveband models and select the effective wavelengths for the distinguishing between Puerariae Lobatae Caulis and Puerariae Lobatae Radix, which provided technical and data support for the development of quick inspection equipment based on HSI. The results showed that MLP model outperformed PLS-DA and SVM models in the accuracy of discrimination with full wavebands in VNIR, SWIR, and VNIR+SWIR lens, which were 95.26%, 99.11%, and 99.05%, respectively. The discriminative band selection(DBS) algorithm was employed to select the effective wavelengths, and the discrimination accuracy was 93.05%, 98.05%, and 98.74% in the three different spectral scopes, respectively. On this basis, the MLP model combined with the effective wavelengths within the range of 2 100-2 400 nm can achieve the accuracy of 97.74%, which was close to that obtained with the full waveband. This waveband can be used to develop quick inspection devices based on HSI for the rapid and non-destructive distinguishing between Puerariae Lobatae Radix and Puerariae Lobatae Caulis.

RESUMO

Zhuru Tang( from the Effective Prescriptions for Universal Relief) listed in the Catalogue of Ancient Classical Formulas( The First Batch) by the State Administration of Traditional Chinese Medicine,is usually used to treat stomach fever and vomiting. The first step of the research and development of the classic formula compound preparations is to follow the principle of the ancient method,comb through the literature of all dynasties,and then investigate the historical evolution of the prescription,the evolution of formula significance and the clinical application. Based on this principle,we searched the Chinese Medical Classics Database and relevant literature materials to conduct textual research on the history,evolution of formula significance,clinical application,decocting method,as well as the basis and processing of traditional Chinese medicine from the perspectives of " recipe" and " medicine",in order to provide reference for the development and research of Zhuru Tang.

RESUMO

The type and frequency of simple sequence repeats( SSRs) in the genomes was investigated using the DNA sequence data of Pueraria lobata and P. thomsonii. Based on these SSRs,20 pairs of SSR primers were designed and 5 high polymorphism primer pairs were selected to analyze genetic diversity of 9 cultivars of P. thomsonii in Jiangxi province. The results showed that the 5 pairs of primers could generate 16 polymorphic alleles bands. The average polymorphism information content( PIC) of each SSR primer pair was 0. 600 7.According to the genetic similarity coefficients,the 9 cultivars of P. thomsonii can be classified into 6 germplasms. This study established DNA identity cards with 5 pairs of SSR primers for different germplasm resources of P. thomsonii in Jiangxi province,which provided reference information for the selection of fine germplasms of P. thomsonii and the theoretical basis for the study of Dao-di herbs.

RESUMO

This study aimed to investigate the anti-inflammatory effects of N-methylcytisine (NMC) in a dextran sulfate sodium (DSS)-induced colitis model and explore its possible mechanisms. Experimental colitis was induced by administering the mice with 5% DSS for 7 days. Different doses of NMC (1, 4 and 16 mg/kg) and 5-aminosalicylic acid (100 mg/kg) were given orally once every day for 7 days. The protective effect of NMC was evaluated using the disease activity index, colon length and results of histopathological examination. The possible mechanisms of NMC were explored by evaluating the expression levels of tumour necrosis factor-α, interleukin-1ß and interleukin-6 (IL-6) using ELISA and analysing the protein expression levels of nuclear factor (NF)-κB p65, p-NF-κB p65, p-IκB, IκB, IκB kinase (IKK) and p-IKK using western blots. Results demonstrated that the oral administration of NMC attenuated the DSS-induced clinical symptoms and pathological damage. In addition, NMC treatment significantly reduced myeloperoxidase activity and level of pro-inflammatory cytokines. Further studies revealed that NMC blocked the activation of NF-κB by inhibiting IκB and IKK phosphorylation. These findings suggested that NMC exerts anti-inflammatory effects on DSS-induced colitis, and its mechanism may be related to the suppression of NF-κB activation. Thus, NMC may have potential therapeutic value in the treatment of colitis.

RESUMO

Increasing evidence demonstrates inflammation contributes to neuronal death following cerebral ischemia. Lycium barbarum polysaccharide (LBP) has been reported to prevent scopolamine-induced cognitive and memory deficits. We recently indicated that LBP exerts neuroprotective effect against focal cerebral ischemic injury in mice via attenuating the mitochondrial apoptosis pathway. The aim of this study was to investigate the neuroprotective effects of LBP against the behavioral dysfunction induced by focal cerebral ischemia injury in mice. Following 7 successive days of pretreatment with LBP (10, 20 and 40 mg/kg) and nimodipine (4 mg/kg) by intragastric gavage, mice were subjected to middle cerebral artery occlusion (MCAO). Following reperfusion, cerebral blood flows, the total power of the spontaneous EEG, and morphological changes were estimated. Learning and memory ability, and motor coordination were determined by Morris water maze task, rotarod and grip test. Western blot analysis, Real-Time fluorogenic PCR assays, and immunofluorescence staining were used to examine the expression of proinflammatory mediators and activation of microglia. The present study showed that LBP pretreatment significantly enhanced regional cortical blood flow and the total power of the spontaneous EEG, improved memory and motor coordination impairments, and inhibited over-activation of microglia and astrocytes after MCAO. Further study demonstrated LBP suppressed MCAO-induced activations of P65 NF-κB and P38 MAPK, and prevented up-regulations of proinflammatory mediators in hippocampus. Our data suggest that LBP can exert functional recovery of memory and motor coordination deficits and neuroprotective effect against cerebral ischemic injury in mice.

RESUMO

Chinese medicine prices often have sharp rise or fall, and even the impact of short-term price rise on the quality of feed can't be ignored.On the other hand, the production of traditional Chinese medicine is strictly subject to resource constraints, so much of the industrial production due to lack of or prohibited use of resources must bestopped. Based on 203 Chinese patent medicines in the National Essential Drugs (2012 Edition), the factors that influence the supply of essential drugs of traditional Chinese medicine were analyzed and seven indicators for the supply of essential medicines were designed in this paper. According to the Chinese herbal medicine resources survey and dynamic monitoring service system data, a multi-index comprehensive evaluation model based on radar chart analysis was proposed, providing a holistic and overall evaluation of the supply situation of essential drugs of traditional Chinese medicine. The evaluation results were concise, clear and intuitive. In this paper, Jiuwei Qianghuo Wan and Ganmao Qingre Keli were taken as the examples to prove that the proposed comprehensive evaluation method is concise, clear, intuitive, credible and practical.

RESUMO

The supply of Chinese patent medicine is influenced by the price of raw materials (Chinese herbal medicines) and the stock of resources. On the one hand, raw material prices show cyclical volatility or even irreversible soaring, making the price of Chinese patent medicine is not stable or even the highest cost of hanging upside down. On the other hand, due to lack of resources or disable some of the proprietary Chinese medicine was forced to stop production. Based on the micro-service architecture and Redis cluster deployment Based on the micro-service architecture and Redis cluster deployment, the supply security monitoring and analysis system for Chinese patent medicines in national essential medicines has realized the dynamic monitoring and intelligence warning of herbs and Chinese patent medicine by connecting and integrating the database of Chinese medicine resources, the dynamic monitoring system of traditional Chinese medicine resources and the basic medicine database of Chinese patent medicine.

RESUMO

BACKGROUND: There has been limited research on the use of non-Saccharomyces yeasts for the production of cherry wines. This work used an autochthonous Torulaspora delbrueckii strain 49 (TD49) in association with a commercial S. cerevisiae RC212 yeast, to investigate the effect of multi-starter culture (sequential inoculation and simultaneous inoculation) and fermentation temperature on the quality of cherry wines. RESULTS: Both TD49 and RC212 proliferated during alcoholic fermentation (AF) under sequential inoculation conditions, whereas in the case of simultaneous inoculation, TD49 increased slowly at first and then declined sharply near the fermentation end. The analytical profile showed that both mixed fermentations produced lower levels of volatile acidy and higher levels of aromatic compounds than those from RC212 mono-culture. During sensory analysis, wines from sequential fermentation obtained the highest score, mainly due to the higher intensity in 'fruity' and 'floral' characters. As for the influence of temperature, a low temperature (20 °C) enhanced TD49 persistence during AF, but the sensory quality decreased anyway; 30 °C resulted in decreases in most measured descriptors. Therefore, 25 °C was selected as the best culture temperature. CONCLUSION: TD49/RC212 sequential inoculation and fermentation at 25 °C significantly enhanced the cherry wine quality.

RESUMO

To explore the pharmacological principle of Artemisia carvifolia,the text mining technique was used. All the references of A. carvifolia were collected from PubMed database, and then the rules of the main ingredient,relative diseases, organs, tissues, proteins and metabolites were analyzed. Finally, a network was set up. Then it was found that the main ingredients included sesquiterpenoids,flavonoids,and volatileoils.The diseases such as malaria, cerebral malaria, falciparum malaria, visceral leishmaniasis and systemic lupus erythematosus were often treated with A. carvifolia. In association in organ were the liver, skin, trachea,lungs,and spleen.Correlations with tissues were mainly including macrophages, T lymphocytes, blood vessels, epithelial cells.The protein was correlation with it involved CYP450, PI3K, TNF-α, AASDPPT, DNA polymerase and so on. Comprehensive and systematic treatment principle of A. carvifolia was obtained by text mining, which was helpful in clinical application.

RESUMO

This paper was aimed to explore the relationship between Artemisia annua and tumor, and investigate its anti-tumor mechanism based on the bioinformatics molecular network analysis, text mining technique and other related methods. Text mining tool Polysearch database was used to get the information, and after formatting conversion, the information was imported into the bioinformatics analysis software Cytoscape3.2.1 for visualization and subsequent bioinformatics molecular network analysis .It was shown that the A. annua was associated with the tumor by 8 key proteins: TNF,VEGF,PI3K, ALDH1, Bcl-2, MicroRNA, p38 and CASP3 by text mining technique. The main biological processes involved in its anti-tumor effect included cell cycle, post-translational protein modification, cell cycle regulation, protein ubiquitination and organelle tissues regulation. The key network analysis showed that the action may be achieved by regulation of triglyceride metabolic process, positive regulation of triglyceride metabolic process, positive regulation of triglyceride catabolic process, regulation of budding cell apical bud growth, negative regulation of mitotic cell cycle, negative regulation of meiotic cell cycle, and positive regulation of transcription factors. The results showed that the anti-tumor effect of A. annua may be associated with regulating lipid metabolism of tumor cells, decomposing large amounts of lipids, releasing energy, reducing the rate of tumor cell division and accelerating tumor cell apoptosis.

RESUMO

Artemisiae Annuae Herba has used as a medicine for more than 2 000 years. To infer based on the modern study results, Artemisiae Annuae Herba used for the treatment of malaria recorded in Zhou Hou Bei Ji Fang before 1 700 years should come from Artemisia annua. Based on the data of Chinese materia medica, from the field of treatment hotness and preventing attack of malaria etc., the Dao-di producing district of Artemisiae Annuae Herba should at Jingzhou (now Hubei) and surrounding areas in history. From the view of anti-malaria components artemisinin content, the Dao-di growing producing district of Artemisiae Annuae Herba should locate at Chongqing, Guangxi and its surrounding provinces. The study results showed that A. annua was harvested in flower bloom at autumn, and in this time it also had higher artemisinin content. If A. annua was stored exceed six months, artemisinin could be degraded about thirty percent. So it should be stored in a cool and dry place generally. Wild A. annua had a rich genetic diversity. Artemisinin content of A. annua breeding in experimental field could reache to two percent.

RESUMO

This study examined the effect of mixed fermentation of non-Saccharomyces (Torulaspora delbrueckii ZYMAFLORE Alpha(TD n. Sacch) and Metschnikowia pulcherrima JS22) and Saccharomyces cerevisiae yeasts (D254 and EC1118) on the production of cherry wines, in comparison with commonly used mono-culture. Results obtained during AF demonstrated that negligible inhibitory effect was observed in S. cerevisiae/Alpha pair, whereas a strong antagonistic effect was detected between MJS22 and S. cerevisiae strain, resulting in an early death of MJS22. For volatile components determined, S. cerevisiae/MJS22 couple was found to significantly boost the production of most detected compounds, more particularly in higher alcohols, esters, acids and terpenes; while the characteristic of S. cerevisiae/Alpha pair is an increase in fruity esters, higher alcohols and decrease in acid production. Sensory evaluation revealed that S. cerevisiae/MJS22 pair reinforced sweet, green and fatty notes to the cherry wines, and S. cerevisiae/Alpha trial enhanced the fruity odour and reduced green note.

RESUMO

PURPOSE: To determine the prevalence of anxiety and depression in patients with nasopharyngeal carcinoma (NPC) and to identify central symptoms and bridge symptoms among psychiatric disorders. METHODS: This cross-sectional study recruited patients with NPC in Guangzhou, China from May 2022, to October 2022. The General Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9) were used for screening anxiety and depression, respectively. Network analysis was conducted to evaluate the centrality and connectivity of the symptoms of anxiety, depression, quality of life (QoL) and insomnia. RESULTS: A total of 2806 respondents with complete GAD-7 and PHQ-9 scores out of 3828 were enrolled. The incidence of anxiety in the whole population was 26.5% (depression, 28.5%; either anxiety or depression, 34.8%). Anxiety was highest at caner diagnosis (34.2%), while depression reached a peak at late-stage radiotherapy (48.5%). Both moderate and severe anxiety and depression were exacerbated during radiotherapy. Coexisting anxiety and depression occurred in 58.3% of those with either anxiety or depression. The generated network showed that anxiety and depression symptoms were closely connected; insomnia was strongly connected with QoL. "Sad mood", "Lack of energy", and "Trouble relaxing" were the most important items in the network. Insomnia was the most significant bridge item that connected symptom groups. CONCLUSION: Patients with NPC are facing alarming disturbances of psychiatric disorders; tailored strategies should be implemented for high-risk patients. Besides, central symptoms (sad mood, lack of energy, and trouble relaxing) and bridge symptoms (insomnia) may be potential interventional targets in future clinical practice.

RESUMO

Trivalent oral poliovirus vaccine (tOPV) has been withdrawn and instead an inactivated poliovirus vaccine (IPV) and bivalent type 1 and type 3 OPV (bOPV) sequential immunization schedule has been implemented since 2016, but no immune persistence data are available for this polio vaccination strategy. This study aimed to assess immune persistence following different polio sequential immunization schedules. Venous blood was collected at 24, 36, and 48 months of age from participants who had completed sequential schedules of combined IPV and OPV in phase III clinical trials. The serum neutralizing antibody titers against poliovirus were determined, and the poliovirus-specific antibody-positive rates were evaluated. A total of 1104 participants were enrolled in this study. The positive rates of poliovirus type 1- and type 3-specific antibodies among the sequential immunization groups showed no significant difference at 24, 36, or 48 months of age. The positive rates of poliovirus type 2-specific antibody in the IPV-IPV-tOPV group at all time points were nearly 100%, which was significantly higher than the corresponding rates in other immunization groups (IPV-bOPV-bOPV and IPV-IPV-bOPV). Immunization schedules involving one or two doses of IPV followed by bOPV failed to maintain a high positive rate for poliovirus type 2-specific antibody.
