Evaluation of Relationship of Pueraria lobata Quality from Different Producing Areas Based on "Climate Factor-component Content-antioxidant Capacity" / 中国实验方剂学杂志

ObjectiveThe correlation of Pueraria lobata producing areas， climate factors， total flavonoids of P. lobata， polysaccharide content of P. lobata， and antioxidant activity of P.lobata for medicinal application was analyzed， and the relationship between climate factors and the formation of P. lobata quality was evaluated. MethodThe scavenging rates of 1,1-diphenyl-2-picrylhydrazyl radical 2,2-diphenyl-1-(2,4,6-trinitrophenyl)hydrazyl（DPPH） and 2, 2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)（ABTS） radicals by total flavonoids and polysaccharides of P. lobata were detected， and the correlation between the contents of each component and the information of producing areas and climate factors was analyzed. ResultThe ABTS+ scavenging rate by total flavonoids of P.lobata was negatively correlated with altitude （P<0.05） and positively correlated with annual sunshine hours （P<0.05）. The altitude was positively correlated with the total flavonoid content， while the annual sunshine hours were negatively correlated with the total flavonoid content. There was a negative correlation between total flavonoid content and ABTS+ scavenging rate by total flavonoids. In other words， lower altitude and longer annual sunshine hours indicated lower total flavonoid content and higher ABTS+ scavenging rate by total flavonoids. The ABTS+ scavenging rate by polysaccharides of P. lobata was negatively correlated with the frost-free period （P<0.05） and the mean temperature in July （P<0.01）. There was a positive correlation between the polysaccharide content of P. lobata and the frost-free period. The mean temperature in July was positively correlated with the polysaccharide content of P. lobata （P<0.05）. The polysaccharide content of P. lobata was negatively correlated with the ABTS+ scavenging rate by polysaccharides of P. lobata. In other words， a shorter frost-free period in the producing area and lower mean temperature in July indicated lower polysaccharide content of P. lobata and higher ABTS+ scavenging rate by polysaccharides of P. lobata. The mean temperature in July was significantly correlated with the contents of total flavonoids and polysaccharides in P. lobata samples （P<0.05）. The lower mean temperature in July was often accompanied by lower total flavonoid content of P. lobata， lower polysaccharide content of Pueraria lobata， and stronger antioxidant activity of P. lobata samples. ConclusionThe ability of P. lobata to remove ABTS+ is stronger than that of DPPH+. There is a significant correlation between climate factors， content， and antioxidant capacity in each producing area. Further research on the internal law of the formation of medicinal active components of P. lobata induced by core climate factors will provide a scientific basis for revealing the formation mechanism of genuine P. lobata and the subsequent control of P. lobata quality according to the environment of producing areas.

Drought is a common limiting factor affecting rice yield and quality. Cerium oxide nanoparticles(nanoceria) have been widely reported to improve crop stress tolerance. However, the effects and mechanisms of nanoceria on rice drought tolerance are still unknown. The aim of this study is to investigate whether nanoceria can improve rice drought tolerance by modulating reactive oxygen species(ROS) homeostasis and nitric oxide(NO) levels. Our results showed that compared with no-nanoparticle treatment, nanoceria significantly increased the fresh weight of rice seedlings under drought stress(19%, P < 0. 05). Also, under drought stress, the ROS level of rice leaves treated with nanoceria was significantly lower(82%, P < 0. 05) than leaves treated with buffer. The leaf NO level after nanoceria treatment, however, is significantly higher(46%, P < 0. 05) than that with no-nanoparticle treatment under drought stress. Moreover, compared with control plants, nanoceria maintained better membrane integrity in rice leaf cells under drought stress, showing a 70% decrease(P < 0. 05) in dead leaf cells. This study explores the mechanisms underlying nanoceria’s improved rice drought tolerance by affecting ROS and NO levels, which not only further enriches our knowledge about the interaction between nanoparticles and crops under abiotic stress but also gives more support on the sustainable development of nano-enabled agriculture.

MiR-326 regulates EphB3 to inhibit invasion and metastasis of breast cancer cells / 中国药理学通报

;Aim To investigate the molecular mechanism of miR-326 inhibiting breast cancer invasion and metastasis by regulating EphB3 expression. Methods RTFQ-PCR was used to examine the expression of miR-326 in normal breast epithelial cells and breast cancer cells and the transfection efficiency of miR-326 overexpression plasmid. EdU cell proliferation assay and Transwell assay were used to examine the changes in proliferation, migration and invasion ability of different subgroups of cells. Dual luciferase assay was used to verify the presence of binding sites for miR-326 and EphB3. Western blot was used to detect the expression of EphB3 in breast cancer cells after overexpression of miR-326. Results RTFQ-PCR results showed that miR-326 was lowly expressed in breast cancer cells and successfully transfected (P < 0. 05). EdU proliferation assay and Transwell assay results showed that overexpression of miR-326 in breast cancer cells inhibited proliferation, migration and invasive ability (P < 0. 05). The results of dual luciferase assay showed that miR-326 could interact with the 3'-UTR of EphB3 (P < 0. 05). Western blot and Transwell assays showed that miR-326 could negatively regulate EphB3 to inhibit invasive metastasis of breast cancer cells (P < 0. 05). Conclusions MiR-326 acts as a cancer suppressor genes in the development of breast cancer and suppresses the invasion and metastasis of breast cancer cells by regulating the expression of EphB3.

Phenotype and genotype analyses of two pedigrees with inherited fibrinogen deficiency / 中华血液学杂志

Objective: To analyze the phenotype and genotype of two pedigrees with inherited fibrinogen (Fg) deficiency caused by two heterozygous mutations. We also preliminarily probed the molecular pathogenesis. Methods: The prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and plasma fibrinogen activity (Fg∶C) of all family members (nine people across three generations and three people across two generations) were measured by the clotting method. Fibrinogen antigen (Fg:Ag) was measured by immunoturbidimetry. Direct DNA sequencing was performed to analyze all exons, flanking sequences, and mutated sites of FGA, FGB, and FGG for all members. Thrombin-catalyzed fibrinogen polymerization was performed. ClustalX 2.1 software was used to analyze the conservatism of the mutated sites. MutationTaster, PolyPhen-2, PROVEAN, SIFT, and LRT online bioinformatics software were applied to predict pathogenicity. Swiss PDB Viewer 4.0.1 was used to analyze the changes in protein spatial structure and molecular forces before and after mutation. Results: The Fg∶C of two probands decreased (1.28 g/L and 0.98 g/L, respectively). The Fg∶Ag of proband 1 was in the normal range of 2.20 g/L, while it was decreased to 1.01 g/L in proband 2. Through genetic analysis, we identified a heterozygous missense mutation (c.293C>A; p.BβAla98Asp) in exon 2 of proband 1 and a heterozygous nonsense mutation (c.1418C>G; p.BβSer473*) in exon 8 of proband 2. The conservatism analysis revealed that Ala98 and Ser473 presented different conservative states among homologous species. Online bioinformatics software predicted that p.BβAla98Asp and p.BβSer473* were pathogenic. Protein models demonstrated that the p.BβAla98Asp mutation influenced hydrogen bonds between amino acids, and the p.BβSer473* mutation resulted in protein truncation. Conclusion: The dysfibrinogenemia of proband 1 and the hypofibrinogenemia of proband 2 appeared to be related to the p.BβAla98Asp heterozygous missense mutation and the p.BβSer473* heterozygous nonsense mutation, respectively. This is the first ever report of these mutations.

Objective To analyze the epidemiological characteristics of newly reported advanced schistosomiasis cases in Sichuan Province, so as to provide the evidence for analyzing the causes and formulating targeted control measures of newly reported advanced schistosomiasis cases. Methods Individual case investigation forms for advanced schistosomiasis cases were collected from the Sichuan Provincial Epidemic Annual Report System from 2011 to 2022, and patients’ demographics, previous medical history and liver parenchymal grading were retrieved. All advanced schistosomiasis cases’ medical records were reviewed, and the subtypes of schistosomiasis-endemic villages where the cases’ household registration were, floating population, survival and death and time of death were collected. Results A total of 321 newly reported advanced schistosomiasis cases were found in Sichuan Province from 2011 to 2022, with a male to female ratio of 0.99 to 1. There were 274 cases at ages of over 50 years (85.4%), with the highest proportion seen at ages of 60 to 69 years (87 cases, 27.1%), and splenomegaly was the most common type (180 cases, 56.1%), with no dwarfism type detected. The highest number of cases was reported in 2011 (78 cases), followed by in 2022 (74 cases), and the highest number of cases were reported in Meishan City (199 cases, 62.0%), Dongpo District (131 cases, 40.8%), and hilly subtype areas (136 cases, 42.4%). As of the end of 2022, there were 111 deaths due to advanced schistosomiasis, with the highest number of deaths seen in 2018 (25 deaths), and the highest mortality was seen among patients with the ascites type (41.2%). There were 47 (37.3%), 40 (59.5%) and 4 (23.5%) cases with grade III liver parenchyma among patients with splenomegaly, ascites, and colonic proliferation types, respectively, and there was a significant difference in the grading of III liver parenchyma among three types of patients (H = 12.092, P < 0.05), with more severe liver parenchyma injuries seen among patients with the ascites type than among those with splenomegaly and colonic proliferation type (Z = 24.262 and 44.738, both Padjusted values < 0.05). Conclusions There have been newly reported advanced schistosomiasis cases in Sichuan Province during recent years, and patients with the ascites type should be given a high priority among advanced schistosomiasis cases in Sichuan Province. Intensified clue surveys are needed for early identification and treatment of advanced schistosomiasis cases, so as to increase the survival rate and improve the quality of life.

Comprehensive evaluation of Pinellia ternata germplasm resources based on phenotypic trait classification / 中国中药杂志

The evaluation of germplasm resources is the prerequisite for the development, utilization, and conservation of Chinese medicinal resources. The selection of excellent germplasm is the key to the breeding and orderly production of Pinellia ternata. In this study, 21 germplasm materials of P. ternata from major production areas in China were collected and analyzed for population diversity after phenotypic preliminary screening. The results have revealed that the P. ternata population has abundant phenotypic variation, and the phenotypic changes could be divided into five phenotypes in terms of organ trait variation. Further analysis of variation in 20 quantitative traits of the population revealed that the coefficient of variation for adenosine content(339.05%) was the largest, while the coefficient of variation for the underground plant height(16.35%) was the smallest. Correlation analysis showed that there was a strong correlation among various traits, with 52 pairs of traits showing highly significant correlation(P<0.01) and 19 pairs of traits showing a significant correlation(P<0.05). The 21 germplasms in the test could be classified into three major clusters by cluster analysis, with Cluster Ⅱ having the highest number and content of nucleosides, making it suitable for the selection and breeding of P. ternata varieties with high content of nucleosides. The yield in Cluster Ⅲ was higher than that in other groups, making it suitable for the selection and breeding of P. ternata varieties with a high yield. All trait indicators could be simplified into five principal component factors through principal component analysis, and the cumulative contribution rate was up to 86.04%. Further, comprehensive analysis using membership function and stepwise regression analysis identified nine traits, such as plant height, main leaf length, and underground plant height as characteristic indicators for the comprehensive evaluation of germplasm resources of P. ternata. BX007, BX008, and BX005 were identified as germplasms with both high yield and high uridine content, with BX007 having the highest uridine content of 479.51 μg·g~(-1). It belonged to the germplasm of P. ternata with double bulbils and could be cultivated as a potential good variety. Based on the phenotypic classification of P. ternata, systematic resource evaluation was carried out in this study, which could lay a foundation for the excavation of genetic resources and the breeding of new varieties of P. ternata.

Contamination of common food-borne pathogens in foods sold in Changzhou / 公共卫生与预防医学

Objective To understand the contamination status of common food-borne pathogens in foods sold in Changzhou, and to provide evidence for food safety risk assessment and prevention of food-borne diseases. Methods From 2010 to 2020 , 2 513 samples of 17 types of foods were collected in Changzhou area. The detection of pathogenic bacteria was carried out in accordance with the standard operation procedure specified in the “Workbook for Surveillance on Food Microorganisms and Pathogenic Factors in Jiangsu Province”. Results A total of 260 positive samples of common food-borne pathogens were detected in all 2 513 samples with an overall detection rate of 10.30%. Single factor analysis showed that the detection rate of pathogenic bacteria in non-ready-to-eat samples was higher than that in ready-to-eat samples (χ2=148.875，P =0.000). The detection rate of pathogenic bacteria in bulk samples was higher than that in prepackaged ones (χ2=70.956，P=0.000). There is a difference in the detection rate of food-borne pathogens from different types of sampling sites (χ2=65.017，P=0.000). Logistic regression analysis showed that ready-to-eat food, packaging type, and sampling season were significantly correlated with the detection rate of food-borne pathogens. The detection rate of pathogenic bacteria in samples collected in the third or fourth quarters was higher than that in the first quarter. Conclusion The commercial foods sold in Changzhou have a relatively high level of contamination of food-borne pathogenic bacteria, and they should be fully heated and sterilized before consumption. The relevant departments should strengthen supervision and health education in summer and autumn.

Prevalence and incidence of heart failure among community in China during a three-year follow-up / 老年心脏病学杂志（英文版）

BACKGROUND@#Epidemiological surveys on heart failure (HF) in Chinese community are relatively lacking. This study aimed to estimate the prevalence and incidence of HF among community residents in southern China.@*METHODS@#Baseline data of this prospective study was collected from 2015 to 2017 among 12,013 permanent residents aged ≥ 35 years in Guangzhou, China. The same survey process was carried out for individuals aged ≥ 65 years after a three-year follow-up.@*RESULTS@#The overall prevalence of HF in community residents aged ≥ 35 years was 1.06%. Male had significantly higher risk of HF prevalence [odds ratio (OR) = 1.50, P = 0.027]. The gender-adjusted risk of HF was 1.48 times higher per 10 years aging. HF prevalence was statistically associated with atrial fibrillation, valvular heart disease, hypertension and chronic obstructive pulmonary disease after adjusting for age and gender (OR = 8.30, 5.17, 1.11, 2.28, respectively; all P < 0.05). HF incidence in individuals aged ≥ 65 years were 847 per 100,000 person-years. Baseline atrial fibrillation, valvular heart disease, and diabetes mellitus were risk factors for HF incidence for individuals aged ≥ 65 years adjusting for age and gender (OR = 5.05, 3.99, 2.11, respectively; all P < 0.05). Besides, residents with new-onset atrial fibrillation and myocardial infarction were at significantly higher risk of progression to HF (OR = 14.41, 8.54, respectively; all P < 0.05).@*CONCLUSIONS@#Both pre-existing and new-onset cardiovascular diseases were associated with HF incidence in southern China. Management of related cardiovascular diseases may be helpful to reduce the incidence of HF.

OBJECTIVE@#To develop and validate a nomogram for predicting outcomes of patients with gastric neuroendocrine neoplasms (G-NENs).@*METHODS@#We retrospectively collected the clinical data from 490 patients with the diagnosis of G-NEN at our medical center from 2000 to 2021. Log-rank test was used to analyze the overall survival (OS) of the patients. The independent risk factors affecting the prognosis of G-NEN were identified by Cox regression analysis to construct the prognostic nomogram, whose performance was evaluated using the C-index, receiver-operating characteristic (ROC) curve, area under the ROC curve (AUC), calibration curve, DCA, and AUDC.@*RESULTS@#Among the 490 G-NEN patients (mean age of 58.6±10.92 years, including 346 male and 144 female patients), 130 (26.5%) had NET G1, 54 (11.0%) had NET G2, 206 (42.0%) had NEC, and 100 (20.5%) had MiNEN. None of the patients had NET G3. The numbers of patients in stage Ⅰ-Ⅳ were 222 (45.3%), 75 (15.3%), 130 (26.5%), and 63 (12.9%), respectively. Univariate and multivariate analyses identified age, pathological grade, tumor location, depth of invasion, lymph node metastasis, distant metastasis, and F-NLR as independent risk factors affecting the survival of the patients (P < 0.05). The C-index of the prognostic nomogram was 0.829 (95% CI: 0.800-0.858), and its AUC for predicting 1-, 3- and 5-year OS were 0.883, 0.895 and 0.944, respectively. The calibration curve confirmed a good consistency between the model prediction results and the actual observations. For predicting 1-year, 3-year and 5-year OS, the TNM staging system and the nomogram had AUC of 0.033 vs 0.0218, 0.191 vs 0.148, and 0.248 vs 0.197, respectively, suggesting higher net benefit and better clinical utility of the nomogram.@*CONCLUSION@#The prognostic nomogram established in this study has good predictive performance and clinical value to facilitate prognostic evaluation of individual patients with G-NEN.

Meta-analysis of Effect of Tripterygium wilfordii Polyglycoside Tablets Combined with Methotrexate and/or Leflunomide on Autoantibodies in Rheumatoid Arthritis / 中国实验方剂学杂志

ObjectiveTo evaluate the effect of Tripterygium wilfordii polyglycoside tablets （TWPT） combined with conventional synthetic disease-modifying antirheumatic drugs （csDMARDs） including methotrexate （MTX） and/or leflunomide （LEF） on autoantibodies in rheumatoid arthritis （RA） patients. MethodPubMed， EMBASE， Web of Science， Cochrane Library， China National Knowledge Infrastructure （CNKI）， VIP， Wanfang Data， and China Biomedical Literature Service System （SinoMed） were searched for randomized controlled trials （RCTs） of TWPT combined with MTX and/or LEF in the treatment of RA patients from database inception to December 1， 2021. Primary outcome indicators included rheumatoid factor （RF） and anti-citrullinated protein antibody （ACPA）， and secondary outcome indicators included immunoglobulin （IgA， IgG， and IgM） and adverse drug events （ADE）. ResultThirty-one RCTs， involving 2 643 adult patients， were included， including 20 RCTs of TWPT combined with MTX， 10 of TWPT combined with LEF， and one of TWPT combined with MTX and TWPT. The follow-up time ranged from two weeks to 13 months. Compared with csDMARDs alone， TWPT combined with other drugs significantly improved serum RF of RA patients ［SMD=-2.45， 95% CI ［-2.97， -1.93］， P<0.000 01］， anti-CCP ［SMD=-1.41， 95% CI （-2.35， -0.48）， P=0.003］， IgM ［SMD=-1.90， 95% CI （-3.03， -0.76）， P=0.001］， and IgA ［SMD=-1.18， 95% CI （-2.23， -0.12）， P=0.03］. There were no significant effects on IgG ［SMD=-1.02， 95% CI （-2.04， 0.01）， P=0.05］ and ADE ［RR=0.87， 95% CI （0.66， 1.15）， P=0.32］. ConclusionThe results of this study show that compared with csDMARDs alone， TWPT combined with csDMARDs can effectively improve the levels of autoantibodies in RA patients without increasing the incidence of ADE. However， due to the limited quality and quantity of the included RCTs， the relevant conclusions are only used as a reference for the clinical diagnosis and treatment of RA， and more high-quality studies are still needed to further confirm their efficacy.

Objective: To analyze and compare the efficacy and safety of pingyangmycin fibrin glue composite (PFG) and pingyangmycin dexamethasone composite (PD) in the treatment of pharyngolaryngeal venous malformation (VM). Methods: The clinical data of 98 patients with pharyngolaryngeal VM who underwent sclerotherapy with pingyangmycin composite in the First Affiliated Hospital of Sun Yat-sen University from June 2013 to November 2022 were retrospectively analyzed. According to their treatment, patients were divided into PFG group (n=34) and PD group (n=64), among those patients there were 54 males and 44 females, aged 1-77(37.06±18.86)years. The lesion size, total treatment times and adverse events were recorded before and after treatment. And the efficacy was divided into three grades: recovery, effective and invalid. According to the length of VM, all patients were divided into three subgroups, to compare the differences in efficacy and treatment times between each two groups.And finally the adverse events and their treatments were analyzed. SPSS 25.0 software was used for statistical analysis. Results: The efficacy of PFG group was 94.11%(32/34), the recovery rate was 85.29%(29/34).And the efficacy of PD group was 93.75%(60/64), the recovery rate was 64.06%(41/64). No serious adverse eventst occurred in subgroup comparison, there was no statistical difference between the two groups in efficacy and the times of treatments when the length was≤3 cm (Zefficacy=1.04, ttreatment times=2.18, P>0.05); when the length was 3-5 cm, there was no significant efficacy difference between the two groups(Zefficacy=1.17, P>0.05), but the treatment times of PFG were less (ttreatment times=4.87, P<0.01); when the length≥5 cm, efficacy of PFG was significantly better than PD (Zefficacy=2.94, P<0.01), and had fewer treatments times (ttreatment times=2.16, P<0.01). There were no serious adverse events in either group during treatment and follow-up. Conclusion: Both PFG and PD are safe and effective composite sclerotherapy agent for the treatment of laryngeal VM, but PFG has a higher cure rate and fewer treatment times for massive lesions.

The basic information of the patients, tumor pathological characteristics, and treatment methods were entered, and the treatment information and survival data after discharge were followed up and recorded. The Kaplan-Meier method was used to construct survival curves, and the log-rank test to analyze the differences in survival between groups. Cox Regression model analysis of risk factors affecting the prognosis of G-NEN patients. Results: Among the 501 cases confirmed as G-NEN, 355 were male and 146 were female, and their median age was 59 years. The cohort comprised 130 patients (25.9%) of neuroendocrine tumor (NET) G1, 54 (10.8%) of NET G2, 225 (42.9%) of neuroendocrine carcinoma (NEC), and 102 cases (20.4%) of mixed neuroendocrine-non-neuroendocrine(MiNEN). Patients NET G1 and NET G2 were mainly treated by endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR). The main treatment for patients with NEC/MiNEN was the same as that for gastric malignancies, namely radical gastrectomy+lymph node dissection supplemented with postoperative chemotherapy. There were significant differences in sex, age, maximum tumor diameter, tumor morphology, tumor numbers, tumor location, depth of invasion, lymph node metastasis, distant metastasis, TNM staging and expression of immunohistological markers Syn and CgA among NET, NEC, and MiNEN patients (all P<0.05). Further for NET subgroup analysis, there were significant differences between NET G1 and NET G2 in the maximum tumor diameter, tumor shape and depth of invasion(all P<0.05). 490 patients (490/501, 97.8%) were followed up with a median of 31.2 months. 163 patients had a death during follow-up (NET G1 2, NET G2 1, NEC 114, MiNEN 46). For NET G1, NET G2, NEC and MiNEN patients,the 1-year overall survival rates were 100%, 100%, 80.1% and 86.2%, respectively; the 3-year survival rates were 98.9%, 100%, 43.5% and 55.1%, respectively. The differences were statistically significant (P<0.001). Univariate analysis showed that gender, age, smoking history, alcohol history, tumor pathological grade, tumor morphology, tumor location, tumor size, lymph node metastasis, distant metastasis, and TNM stage were associated with the prognosis of G-NEN patients (all P<0.05). Multivariate analysis showed that age ≥60 years, pathological grade of NEC and MiNEN, distant metastasis, and TNM stage III-IV were independent factors influencing the survival of G-NEN patients (all P<0.05). 63 cases were stage IV at initial diagnosis. 32 of these were treated with surgery and 31 with palliative chemotherapy. Stage IV subgroup analysis showed that the 1-year survival rates were 68.1% and 46.2% in the surgical treatment and palliative chemotherapy groups, respectively, and the 3-year survival rates were 20.9% and 10.3%, respectively; the differences were statistically significant (P=0.016). Conclusions: G-NEN is a heterogeneous group of tumors. Different pathological grades of G-NEN have different clinicopathological features and prognosis. Factors such as age ≥ 60 years old, pathological grade of NEC/MiNEN, distant metastasis, stage III, IV mostly indicate poor prognosis of patients. Therefore, we should improve the ability of early diagnosis and treatment, and pay more attention to patients with advanced age and NEC/MiNEN. Although this study concluded that surgery improves the prognosis of advanced patients more than palliative chemotherapy, the value of surgical treatment for patients with stage IV G-NEN remains controversial.

A case of stage Ⅲ pneumoconiosis with large shadow by burr-like changes misdiagnosed as lung cancer / 中华劳动卫生职业病杂志

Pneumoconiosis is characterized by chronic lung inflammation and fibrosis, and inflammation can promote pulmonary fibrosis, which in turn leads to pneumoconiosis. When a large shadow with a long diameter of not less than 2 cm and a short diameter of not less than 1 cm appears in the lung, it can be classified as stage Ⅲ pneumoconiosis. This paper reports a case of stage Ⅲ pneumoconiosis with a large shadow in the upper right lung accompanied by burr-like changes misdiagnosed as lung cancer by CT examination.When the large shadow lesions in patients with pneumoconiosis and lung cancer are difficult to distinguish on CT, an additional MRI examination, particularly T(2)W imaging sequence is useful sequence for identifying the two.

Traditional Chinese medicine microbiomics and its research strategies / 中国中药杂志

The tight relationships between microbiome and traditional Chinese medicine(TCM)have been widely recognized. New technologies, results, and theories are emerging in the field of microbiomics in recent years with the advances in high-throughput sequencing and multi-omics technologies. Based on the previous research, the present study has proposed the concept of TCM microbiomics(TCMM), which is an interdisciplinary subject aiming at elucidating the functions and applications of microbiome in the areas of herb resources, herb processing, herb storage, and clinical effects by using modern technology of biology, ecology, and informatics. This subject essentially contains the structures, functions, interactions, molecular mechanisms, and application strategies of the microbiome associated with the quality, safety, and efficacy of TCM. Firstly, the development of the TCMM concept was summarized, with the profound understanding of TCMM on the complexity and entirety of microbiome being emphasized. Then, the research contents and applications of TCMM in promoting the sustainable development of herb resources, improving the standardization and diversification of herb fermentation, strengthening the safety of herb storage, and resolving the scientific connotation of theories and clinical efficacy of TCM are reviewed. Finally, the research strategies and methods of TCM microbiomics were elaborated from basic research, application research, and system research. TCMM is expected to promote the integrative development of TCM with frontier science and technology, thereby expanding the depth and scope of TCM study and facilitating TCM modernization.

Hepatotoxicity and mechanism of Rhododendri Mollis Flos based on zebrafish model / 中国中药杂志

This study used the zebrafish model to explore the hepatotoxicity of Rhododendri Mollis Flos(RMF). The mortality was calculated according to the number of the survival of zebrafish larvae 4 days after fertilization under different concentration of RMF, and the dose-toxicity curve was fitted to preliminarily evaluate the toxicity of RMF. The liver phenotypes under the sublethal concentration of RMF in the treatment group and the blank control group were observed by hematoxylin-eosin(HE) staining and acridine orange(AO) staining. Meanwhile, the activities of alanine aminotransferase(ALT) and aspartate aminotransferase(AST) were determined to confirm the hepatotoxicity of RMF. Real-time quantitative polymerase chain reaction(real-time PCR) and Western blot were used to determine the expressions of genes and proteins in zebrafish larvae. Gas chromatography time-of-flight mass spectrometry(GC-TOF-MS) was used to conduct untargeted metabolomics testing to explore the mechanism. The results showed that the toxicity of RMF to zebrafish larvae was dose-dependent, with 1 100 μg·mL~(-1) of the absolute lethal concentration and 448 μg·mL~(-1) of sublethal concentration. The hepatocyte apoptosis and degeneration appeared in the zebrafish larvae under the sublethal concentration of RMF. The content of ALT and AST in zebrafish larvae at the end of the experiment was significantly increased in a dose-dependent manner. Under the sublethal concentration, the expressions of genes and proteins related to apoptosis in zebrafish larvae were significantly increased as compared with the blank control group. The results of untargeted metabolomics showed that the important metabolites related to the he-patotoxicity of RMF were mainly enriched in alanine, aspartic acid, glutamic acid, and other pathways. In conclusion, it is inferred that RMF has certain hepatotoxicity to zebrafish larvae, and its mechanism may be related to apoptosis.

Development of flow cytometry and its application in plant research / 生物工程学报

Flow cytometry is a multi-parameter, rapid and efficient method for qualitative analysis and quantitative determination of various fluorescently labeled particles in liquid flow. Flow cytometry has been applied in multiple disciplines such as immunology, virology, molecular biology, cancer biology and infectious disease monitoring. However, the application of flow cytometry in plant research is hampered due to the special composition and structure of plant tissues and cells, such as cell walls and secondary metabolites. In this paper, the development, composition and classification of flow cytometry were introduced. Subsequently, the application, research progress and application limitations of flow cytometry in plant field were discussed. At last, the development trend of flow cytometry in plant research was prospected, which provides new perspectives for broadening the potential application scope of plant flow cytometry.

The common morphology and clinical significance of the axillary arch / 中华外科杂志

Axillary arch is the most common type of axillary muscle fiber variation, with about 10.8% incidence in the Chinese population. Its natural forms are varied and fluid, with different starting points and terminations, and clinicians frequently lack recognition. Under commonly applicated sentinel lymph node biopsy, the axillary arch has been endowed with more clinical significance. The fabric of axillary arch will not only block lymphatic drainage in axilla and unclear anatomical level of axillary dissection, but also compress the axillary neurovascular bundle, causing upper limb venous thrombosis, lymphedema and nerve entrapment. The intumescent axillary arch may also show abnormal axillary bulge. In addition to finding axillary arch during cadaveric study and operation, several of imaging methods availably diagnose axillary arch preoperative, which can create new way for detection of axillary arch and extension of the surgical plan of sentinel lymph node biopsy. Although embryology and comparative anatomy have been used to explain the origin of the axillary arch, most of the ideas are still hypotheses and need further study.
