ABSTRACT

To explore the changes and the reaction mechanisms between soil microecological environment and the content of secon-dary metabolites of plants under water deficit, this study carried out a pot experiment on the 3-leaf stage seedlings of Rheum officinale to analyze their response mechanism under different drought gradients(normal water supply, mild, moderate, and severe drought). The results indicated that the content of flavonoids, phenols, terpenoids, and alkaloids in the root of R. officinale varied greatly under drought stresses. Under mild drought stress, the content of substances mentioned above was comparatively high, and the content of rutin, emodin, gallic acid, and(+)-catechin hydrate in the root significantly increased. The content of rutin, emodin, and gallic acid under severe drought stress was significantly lower than that under normal water supply. The number of species, Shannon diversity index, richness index, and Simpson index of bacteria in the rhizosphere soil were significantly higher than those in blank soil, and the number of microbial species and richness index decreased significantly with the aggravation of drought stresses. In the context of water deficit, Cyanophyta, Firmicutes, Actinobacteria, Chloroflexi, Gemmatimonadetes, Streptomyces, and Actinomyces were the dominant bacteria in the rhizosphere of R. officinale. The relative content of rutin and emodin in the root of R. officinale was positively correlated with the relative abundance of Cyanophyta and Firmicutes, and the relative content of(+)-catechin hydrate and(-)-epicatechin gallate was positively correlated with the relative abundance of Bacteroidetes and Firmicutes. In conclusion, appropriate drought stress can increase the content of secondary metabolites of R. officinale from physiological induction and the increase in the association with beneficial microbe.

ABSTRACT

OBJECTIVES@#To study the clinical characteristics of plastic bronchitis (PB) in children and investigate the the risk factors for recurrence of PB.@*METHODS@#This was a retrospective analysis of medical data of children with PB who were hospitalized in Children's Hospital of Chongqing Medical University from January 2012 to July 2022. The children were divided into a single occurrence of PB group and a recurrent PB group and the risk factors for recurrence of PB were analyzed.@*RESULTS@#A total of 107 children with PB were included, including 61 males (57.0%) and 46 females (43.0%), with a median age of 5.0 years, and 78 cases (72.9%) were over 3 years old. All the children had cough, 96 children (89.7%) had fever, with high fever in 90 children. Seventy-three children (68.2%) had shortness of breath, and 64 children (59.8%) had respiratory failure. Sixty-six children (61.7%) had atelectasis and 52 children (48.6%) had pleural effusion. Forty-seven children (43.9%) had Mycoplasma pneumoniae infection, 28 children (26.2%) had adenovirus infection, and 17 children (15.9%) had influenza virus infection. Seventy-one children (66.4%) had a single occurrence of PB, and 36 cases (33.6%) had recurrent occurrence of PB (≥2 times). Multivariate logistic regression analysis showed that involvement of ≥2 lung lobes (OR=3.376) under bronchoscopy, continued need for invasive ventilation after initial removal of plastic casts (OR=3.275), and concomitant multi-organ dysfunction outside the lungs (OR=2.906) were independent risk factors for recurrent occurrence of PB (P<0.05).@*CONCLUSIONS@#Children with pneumonia accompanied by persistent high fever, shortness of breath, respiratory failure, atelectasis or pleural effusion should be highly suspected with PB. Involvement of ≥2 lung lobes under bronchoscopy, continued need for invasive ventilation after initial removal of plastic casts, and concomitant multi-organ dysfunction outside the lungs may be risk factors for recurrent occurrence of PB.

ABSTRACT

Dengzhan Shengmai capsule, as a compound Chinese patent medicine, consists of four herbs: Herba Erigerontis, Ginseng, Ophiopogon, and Schisandrae Chinensis Fructus, and contains significant components of flavonoids, lignans, saponins, and organic acids. It is widely used clinically to treat cerebrovascular diseases such as chronic cerebral hypoperfusion and dementia with remarkable efficacy. This study proposes a research strategy for multi-component traditional Chinese medicine metabolites based on prediction databases and unfolds the analysis using Dengzhan Shengmai capsule as an example. Using the UPLC-Q-TOF/MS method, the analytical method was established and detected biological samples such as urine, feces, and bile of rats before and after administration based on the prediction of theoretical metabolites of Dengzhan Shengmai capsule. The possible secondary fragment ion information of metabolites was identified by comparing the detected results with prediction databases. The metabolites were identified based on the archetypal component mass spectrometric cleavage law and multistage mass spectrometric data. 51 metabolites, mainly flavonoid, organic acid, and lignan constituents, were finally identified from rat biosamples based on 306 theoretical metabolites of Dengzhan Shengmai capsule. This study provides a new strategy for the identification of metabolites in vivo and the analysis of metabolic pathways of TCM. The study complied with the procedures established by the Animal Experiment Ethics Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences and passed the animal experiment ethics examine (No. 00003645).

ABSTRACT

Yinchenzhufu decoction (YCZFD) is a classic formula for treating Yin Huang syndrome, which can improve liver injury caused by cholestasis. However, the mechanism of action of YCZFD still remains unclear. This article used network pharmacology, molecular docking, animal experiments, and molecular biology methods to explore the mechanism of YCZFD in treating liver injury caused by cholestasis. A mouse model of acute cholestasis induced by lithocholic acid was used to investigate the effects of YCZFD on liver injury. The experimental procedures described in this paper were reviewed and approved by the Ethical Committee at the Shanghai University of Traditional Chinese Medicine (approval NO. PZSHUTCM190823002). The results showed that YCZFD could reduce the levels of blood biochemical indicators and improve hepatocyte damage of cholestatic mice. Then, multiple databases were used to predict the corresponding targets of YCZFD active components on cholestatic liver injury. An intersection target protein-protein interaction (PPI) networks based on String database and Cytoscape software was used to demonstrate the possible core targets of YCZFD against cholestatic liver injury. The results indicated that core targets of YCZFD include tumor necrosis factor, interleukin-1β, non-receptor tyrosine kinase Src, interleukin-6, etc. GO (gene ontology) and KEGG (kyoto encyclopedia of genes and genomes) enrichment analysis indicated that YCZFD may regulate the tumor necrosis factor signaling pathway, nuclear factor-κB signaling pathway, bile secretion, and other related factors to ameliorate the cholestatic liver injury. AutoDockTools software was used to perform molecular docking verification on the core targets and components of YCZFD. To verify the results of network pharmacology, UPLC-MS/MS method was used to determine the effect of YCZFD on levels of bile acid profiles in mouse liver tissues. It was found that treatment with YCZFD significantly reduced the content of free bile acids, taurine bound bile acids, and total bile acids in the liver tissues of cholestatic mice. Then, results from real time PCR and Western blot also found that YCZFD can upregulate the expression of hepatic nuclear receptor farnesoid X receptor, metabolizing enzyme (UDP glucuronidase transferase 1a1), and efflux transporters (bile salt export pump, multidrug resistance-associated protein 2, multidrug resistance-associated protein 3, etc) in cholestasis mice, promote bile acid metabolism and excretion, and improve bile acid homeostasis. Moreover, YCZFD can also inhibit pyroptosis and inflammation by regulating NOD-like receptors 3 pathway, thereby inhibiting cholestatic liver injury.

ABSTRACT

OBJECTIVES@#To investigate the levels of fat-soluble vitamins A, D, and E in children with obesity and their influencing factors.@*METHODS@#A total of 273 children with obesity who attended the Department of Clinical Nutrition, Xi'an Children's Hospital, from January 2019 to April 2021 were enrolled as the obesity group. A total of 226 children with normal body weight who underwent physical examination during the same period were enrolled as the control group. Anthropometric parameters and body composition were measured for both groups, and the serum concentrations of vitamins A, D, and E were also measured.@*RESULTS@#Compared with the control group, the obesity group had significantly higher serum levels of vitamin A [(1.32±0.21) μmol/L vs (1.16±0.21) μmol/L, P<0.001] and vitamin E [(9.3±1.4) mg/L vs (8.3±1.2) mg/L, P<0.001] and a significant reduction in the level of 25-hydroxyvitamin D [(49±22) nmol/L vs (62±24) nmol/L, P<0.001]. In the obesity group, the prevalence rates of marginal vitamin A deficiency, vitamin D deficiency/insufficiency, and vitamin E insufficiency were 5.5% (15/273), 56.8% (155/273), and 4.0% (11/273), respectively. After adjustment for body mass index Z-score and waist-to-height ratio, serum vitamin A level was positively correlated with age (P<0.001), while vitamins E and 25-hydroxyvitamin D levels were negatively correlated with age in children with obesity (P<0.001). After adjustment for age, the serum levels of vitamin A, vitamin E and 25-hydroxyvitamin D were not correlated with degree of obesity, percentage of body fat, and duration of obesity in children with obesity, while the serum levels of vitamins A and E were positively correlated with waist-to-height ratio (P<0.001).@*CONCLUSIONS@#There are higher serum levels of vitamins A and E in children with obesity, especially in those with abdominal obesity, while serum vitamin D nutritional status is poor and worsens with age. Therefore, vitamin D nutritional status should be taken seriously for children with obesity, and vitamin D supplementation should be performed when necessary.

ABSTRACT

The clinical comprehensive evaluation of drugs is an important basis for the return of clinical value, decision-making of medical and health authorities, and allocation of medical resources. In July 2021, the National Health Commission issued the Guidelines for the Management of Clinical Comprehensive Evaluation of Drugs(trial version 2021), which required the evaluation to be implemented from the six dimensions(safety, effectiveness, economy, innovation, suitability, and accessibility), and made detailed arrangements for the clinical comprehensive evaluation of drugs. As Chinese patent medicine differs from chemical medicines in terms of effective components and action modes, the clinical comprehensive evaluation of Chinese patent medicine should highlight the characteristics and advantages of traditional Chinese medicine(TCM) on the basis of general requirements of comprehensive clinical evaluation of drugs. At present, in the clinical comprehensive evaluation of Chinese patent medicine, unified report standards have not yet been generated, resulting in the uneven quality of existing reports. To standardize the clinical comprehensive evaluation report of Chinese patent medicine and improve its quality, the editorial team, based on the relevant policy documents of clinical comprehensive evaluation of drugs, formulated the clinical comprehensive evaluation report standards for Chinese patent medicine in combination with the previous practice and expert opinions. The report standards, containing seven sections with 15 items determined, focus on data source, evaluation content, evidence synthesis, quality control, and evaluation results supported with detailed interpretations to help researchers better understand and apply the report standards for clinical comprehensive evaluation of Chinese patent medicine, improve the report quality, and provide references for the decision-making by the national medical management authorities.

ABSTRACT

Due to the limited resource of bear bile powder, the major raw material of Tanreqing Capsules(TRQ), cultured bear bile powder is used as a replacement to develop the Tanreqing Capsules Substitute(TRQS). An LC-MS/MS method was established in this study for simultaneous quantitation of 8 compounds from TRQS in rat plasma: tauroursodeoxycholic acid(TUDCA), taurocheno-deoxycholic acid(TCDCA), ursodeoxycholic acid(UDCA), chenodeoxycholic acid(CDCA), ferulic acid, wogonoside, baicalin, and forsythoside A. Thereby, the pharmacokinetic behaviors of TRQ and TRQS were evaluated. Concentration of endogenous compounds TUDCA, TCDCA, UDCA, and CDCA was determined with the stable isotope surrogate analytes: D4-TUDCA, D4-TCDCA, D4-UDCA, and D4-CDCA. Plasma samples were extracted by acetonitrile-induced protein precipitation. The LC conditions are as follows: Waters BEH C_(18) column(2.1 mm×100 mm, 1.7 μm), mobile phase of 10 mmol·L~(-1) ammonium formate aqueous solution(containing 0.01% formic acid) and acetonitrile-methanol mixture(1∶5). MS conditions are as below: multiple reaction monitoring(MRM), ESI~(+/-). Concentration of UDCA, CDCA, TUDCA, and TCDCA was corrected with a response factor, which is the ratio between the responses recorded for the surrogate and the authentic analyte at the equal concentration. Each of the plasma components showed good linearity(r > 0.995 1). Accuracy and precision met the criteria(inter-day RSD<7.0%, RE 89.98%-112.0%; intra-day RSD<12%, RE 90.41%-111.2%). The recovery was 64.83%-119.9% and matrix effect was 87.15%-113.8%. The validated method was applied for pharmacokinetic study of TRQS and TRQ(po, 0.94 g·kg~(-1)). There was no significant difference in C_(max) and AUC_(0-24 h) of baicalin, UDCA, TUDCA, and TCDCA between the two groups, indicating similar pharmacokinetic behaviors between TRQS and TRQ in rats.

ABSTRACT

Due to the profound theoretical rationale, perfect diagnosis and treatment system, and characteristic medicinal resources, Tibetan medicine has been passed down to the present day as one of the four traditional medicine systems all over the world. With the development of modern society and the change in people's concept of seeking medical services, Tibetan medicine has gradually attracted wide attention by virtue of its natural, green and safe diagnosis and treatment characteristics, which enables it to be vigo-rously developed and inherited. There are numerous ancient books on Tibetan medicine, covering a large number of ancient prescriptions, which has laid a solid foundation for later scholars to thoroughly investigate the diagnosis and treatment rules in Tibetan medicine and apply them to modern clinical practice. Screening the classic prescriptions that meet modern clinical needs from those numerous ancient books is a new direction in the inheritance and development of Tibetan medicine. On the basis of historical origin and current application status of ancient prescriptions in Tibetan medicine, this paper preliminarily elaborated the definition of classic prescriptions of Tibetan medicine and their general screening principles and precautions, and also discussed the modern inheritance paths of classic prescriptions in Tibetan medicine from basic research, post-marketing evaluation, and the development of novel preparations. Considering the shortcomings in the present study, the key technical issues mentioned need to be more deeply explored and analyzed in future studies.

ABSTRACT

Objective: Chrysophanol (Chry) displays potent anticancer activity in human cancer cells and animal models, but the cellular targets of Chry have not been fully defined. Herein, we speculated whether mitochondria were a target involved in Chry-induced cytotoxicity. Methods: Human liver cancer cell line HepG2 was incubated. The cytotoxicity was evaluated by MTT assay. Mitochondria localization was evaluated by a confocal microscopy. Mitochondrial membrane potential ΔΨm was detected by TMRE staining and determined by the flow cytometer. The levels of ATP, mitochondrial superoxide anions, and GSH/GSSG were determined according to the assay kits. The apoptosis were evaluated through Hoechst33342/PI and Annexin V/PI staining, respectively. The expression of cyclophilin D (CyPD) was determined by immunoblot method, and the interaction between CyPD and Chry was analyzed by molecule docking procedure. Results: Chry itself mainly localized in mitochondria to cause mitochondrial dysfunction and cell death in HepG2 cells. As regard to the mechanism, cyclosporin A as the inhibitor for the formation of mitochondrial permeability transition pore (mPTP) moderately suppressed cell death, indicating mPTP involved in the process of cell death. Further, Chry enhanced the protein expression of Cyclophilin D (CyPD) which is a molecular componentry and a modulator of mPTP, while antioxidant N-acetyl-L-cysteine inhibited the expression of CyPD. Molecule docking procedure disclosed two hydrogen-bonds existed in CyPD-Chry complex with −11.94 kal/mol of the binding affinity value. Besides, the mtDNA-deficient HepG

ABSTRACT

Objective@#To investigate the relation between nicotinic acetylcholine receptor subunit (nAChR) genes and schizophrenia, and the relation between tag single nucleotide polymorphism (rs1317286, rs1044396, rs6494212, rs16969968, and rs684513) and schizophrenia in Han Chinese people. @*Methods@#The protein-protein interaction (PPI) network among nAChR protein and 350 proteins encoded by schizophrenia-related susceptibility genes was constructed through the String database to explore whether nAChR genes were associated with schizophrenia in these known databases. Then, five single nucleotide polymorphisms (SNPs) of CHRNA3 (rs1317286), CHRNA4 (rs1044396), CHRNA7 (rs6494212), and CHRNA5 (rs16969968, rs684513) were analyzed in a sample of 1,035 schizophrenic patients and 816 healthy controls. The interaction between the markers was analyzed using multifactor dimensionality reduction (MDR) software. Power analysis was performed using the Quanto program. @*Results@#There are no significant differences in genotype or allele distribution were identified between the patients and controls (p>0.05). The haplotypes constructed by four markers rs1317286, rs6494212, rs16969968, and rs684513 were not associated with schizophrenia either. However, a significant association between models made of rs1317286, rs1044396, rs6494212, and rs684513 and schizophrenia was revealed in interaction analysis (p<0.05). @*Conclusion@#The nAChR protein may have effects on the development of schizophrenia through the interaction with proteins encoded by schizophrenia-related susceptibility genes, but no relation was found between selected polymorphisms and schizophrenia in the collected Han Chinese people. However, interaction analysis suggested four-SNP model has an important effect on schizophrenia.

Objective:To establish a new fast and accurate method for identifying the authenticity and specifications of Fritillariae Cirrhosae Bulbus based on electronic nose technology, and to discuss the feasibility of this technology in the identification of decoction pieces. Method:Fritillariae Cirrhosae Bulbus was used as the research object, 80 batches of samples to be tested were collected, and the olfactory sensory data of the electronic nose were taken as independent variables (<italic>X</italic>), the results of the method contained in the 2020 edition of <italic>Chinese Pharmacopoeia</italic> were taken as the focus, and the traditional empirical identification results were used as benchmarking information (<italic>Y</italic>). Four chemometric methods, including discriminant analysis (DA), least square support vector machine (LS-SVM), principal component analysis-DA (PCA-DA) and partial least squares-DA (PLS-DA), were used to establish the identification model [<italic>Y</italic>=<italic>F</italic>(<italic>X</italic>)] of authenticity and commodity specifications of Fritillariae Cirrhosae Bulbus, respectively. Wherein, the identification accuracy and time-consuming was taken as indicators to discuss the results. Result:After cross-verification by leave-one-out method, the correct rates of the above four models were 93.75%, 91.25%, 95.00% and 95.00%, respectively, and the PCA-DA and PLS-DA identification models were the best in terms of authenticity identification. In specification identification, the correct rates of these four models were 86.67%, 88.00%, 89.33% and 68.00%, respectively, and the PCA-DA identification model was the best. The electronic nose had a high accuracy in the identification of authenticity and specification model, and the time consuming was relatively short. Conclusion:Electronic nose technology can identify Fritillariae Cirrhosae Bulbus accurately and quickly, and has significant advantages in terms of timeliness and correct judgment rate.

ABSTRACT

Objective:To study the clinical efficacy of modified Shengyutang on patients with active stage psoriasis vulgaris due to Qi and blood deficiency. Method:The 134 cases were randomly divided into control group and observation group, with 67 cases in each group. The control group was given avic a capsule + Danggui Buxuewan, while the observation group was given avic a capsule + modified Shengyutang for 4 weeks, respectively. The psoriasis area and severity index (PASI), dermatological life quality index (DLQI) and psoriasis vulgaris due to Qi and blood deficiency syndrome were observed before and after treatment. The serum growth factor [endothelial cell specific molecule-1 (ESM-1), transforming growth factor-<italic>β</italic><sub>1</sub>(TGF-<italic>β</italic><sub>1</sub>), vascular endothelial cell growth factor (VEGF)], hemorheological indicators [high cut blood viscosity (HBV), low cut blood viscosity (LBV), erythrocyte sedimentation rate (ESR)], CC cphenotype receptor(CCR)6, CC cphenotype ligand 20 (CCL20), monocyte chemotactic protein-4 (MCP-4) in serum and tissue fluid of lesions were detected. Clinical efficacy and recurrence follow-up for 12 months were compared. The safety was evaluated between two groups. Result:Three cases in control group and one case in observation group fell off during the study period. The total effective rate was 96.97% (64/66) in observation group, which was higher than 81.25% (52/64) in control group (<italic>χ</italic><sup>2</sup>=5.064, <italic>P</italic><0.05). During the 12-month follow-up, the recurrence rate was 20.31% (13/64) in observation group, which was lower than 51.92% (27/52) in control group (<italic>χ</italic><sup>2</sup>=6.038, <italic>P</italic><0.05). Compared with control group after treatment, PASI, DLQI, TCM syndromes, ESM-1, TGF-<italic>β</italic><sub>1</sub>, VEGF, HBV, LBV, ESR, CCR6, CCL20 and MCP-4 in observation group were significantly reduced (<italic>P</italic><0.05). No obvious blood and urine routine, or heart, liver and renal dysfunction was observed in the two groups. The incidence of adverse reactions was 3.03% (2/66) in observation group, which was lower than 26.56% (17/64) in control group (<italic>χ</italic><sup>2</sup>=5.764, <italic>P</italic><0.05). Conclusion:Modified Shengyutang can significantly improve the clinical symptoms of patients with active stage psoriasis vulgaris due to Qi and blood deficiency, with a low recurrence rate and the incidence of adverse reactions.

ABSTRACT

Qingkailing Injection is one of the most commonly used traditional Chinese medicine injections with significant clinical application for the treatment of multiple diseases. This study aims to analyze the systematic reviews( SRs) of Qingkailing Injection,in order to provide reference for the clinical application of Qingkailing Injection and the development of relevant clinical practice guidelines. We searched CNKI,CBM,Wanfang,VIP,Pub Med,Cochrane Library and EMbase to collect SRs from the time of database establishment to August 2020. The eligible SRs were included according to the inclusion and exclusion criteria. AMSTAR 2 was used to assess the methodological quality. The diseases,drugs in combinations and results were extracted and analyzed. A total of 24 SRs were selected,including 10 for the treatment of acute cerebrovascular diseases,9 for respiratory infections,2 for viral hepatitis,1 for chronic obstructive pulmonary disease,and two for the adverse effects of Qingkailing Injection. Only three entries of AMSTAR 2 item were fully reported by over 70%,and the rest were reported by less than 70%,with no report about item 2,3 and 10. Twenty-nine outcome indicators were correlated with the included SRs,of which three mostly frequent outcomes were effectiveness,adverse reaction,and neurological deficit scores,showing a good efficacy of Qingkailing Injection. The common severe adverse reaction was anaphylaxis,and mild adverse reactions were skin and mucous membrane reactions. The most frequently combined drug was antibiotics,mainly Penicillin and Penicillin+Pioneeromycin. The existing evidences showed that the methodological quality of SRs of Qingkailing Injection needed to be improved and Qingkailing Injection had an obvious efficacy. However,the selection of outcome indicators for clinical trials and SRs shall be standardized,and the reporting of basic information,such as drug combination,shall be strengthened to provide more powerful clinical services.

ABSTRACT

Objective To investigate the prognosis of two rare imported patients with human African trypanosomias (HAT) after treatment in a follow-up study, and to evaluate the therapeutic efficacy, so as to provide insights into the treatment of imported HAT patients. Methods The white blood cells in cerebrospinal fluid samples and the trypomastigotes in cerebrospinal fluid and blood samples were monitored in an imported case with Trypanosoma brucei rhodesiense infection 1, 3, 11 and 25 months post-treatment and in an imported case with T. brucei gambiense infection 1, 3, 8 and 12 months post-treatment to evaluate the therapeutic efficacy and prognosis. Results There were 1, 1, 4 and 2 white blood cells in per μL of cerebrospinal fluid in the case with T. brucei rhodesiense infection 1, 3, 11 and 25 months post-treatment, and there were 3, 6, 4 and 3 white blood cells in per μL of cerebrospinal fluid in the case with T. brucei gambiense infection 1, 3, 8 and 12 months post-treatment. In addition, no trypomastigotes were identified in the cerebrospinal fluid or blood samples of either case with T. brucei rhodesiense or T. brucei gambiense infection. Conclusion Following standardized treatment, two imported cases with human African trypanosomiasis cases recover satisfactorily, without any signs of relapse.
