Classification Changes of Origin Plants of Traditional Chinese Medicine Based on APG Ⅳ System / 中国实验方剂学杂志

ObjectiveThe angiosperm phylogeny group （APG） Ⅳ system is currently the latest angiosperm classification system. The APG system based on DNA sequence can more naturally reflect the phylogeny and evolution of plants， which has been widely recognized and applied in scientific research and teaching of plants in other countries. Through the comparison between the changes in the APG Ⅳ system and the traditional plant classification system， the changes in the taxonomic status of the original plants of traditional Chinese medicine （TCM） in the 2020 edition of Chinese Pharmacopoeia were reviewed. MethodBy referring to the literature in China and abroad， the changes in the taxonomic status of the original plants of TCM recorded in Chinese Pharmacopoeia were sorted out according to the basic groups of angiosperms in the APG Ⅳ system， including the basal group of ANA， the magnoliid and chloranthales， the basal groups of monocots and eudicots， the superrosids， and the superasterids. ResultThere are about 72 species of TCM in the 2020 edition of Chinese Pharmacopoeia. A total of 76 species of the original plants change in family grade according to the APG Ⅳ system. There are 22 species of TCM belonging to the dicotyledon class， involving 26 species of the original plants. It should be placed in front of the differentiation of monocotyledons and eudicotyledons according to the APG Ⅳ system. ConclusionThis paper largely clarifies the change in the taxonomic status of the original plants of TCM in Chinese Pharmacopoeia according to the APG Ⅳ system， which is helpful to the reviewing literature in China and abroad for the original plants of TCM and facilitates the international academic exchange for TCM. It provides a reference for the revision of textbooks such as Botany and Medicinal Botany in Chinese colleges and universities and will lay the foundation for updating the content of Chinese Pharmacopoeia in the future.

Efficacy of ursodeoxycholic acid in the prevention and treatment of COVID-19 in patients with chronic hepatitis B / 临床肝胆病杂志

ObjectiveTo investigate the potential effect of ursodeoxycholic acid （UDCA） in the prevention and treatment of COVID-19 in patients with chronic hepatitis B. MethodsClinical data were collected from 324 patients with chronic hepatitis B who were treated in Beijing Ditan Hospital， Capital Medical University， from January to December 2022， and according to whether UDCA was administered， they were divided into UDCA group and control group. The propensity score matching （PSM） method was used to balance the confounding factors such as age， sex， and chronic complications， and the two groups were compared in terms of SARS-CoV-2 infection rate， symptoms， and recovery time after COVID-19. The two groups were also compared in terms of related laboratory markers （white blood cell count ［WBC］， hemoglobin ［Hb］， platelet count ［PLT］， alanine aminotransferase ［ALT］， aspartate aminotransferase ［AST］， albumin ［Alb］， alkaline phosphatase ［ALP］， total bilirubin ［TBil］， triglyceride ［TG］， and total cholesterol ［TC］）， vaccination， and the incidence rate of liver disease symptoms after COVID-19. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of data with skewed distribution between the two groups； the chi-square test and the continuously corrected chi-square test were used for comparison of categorical data between two groups. The binary Logistic regression model was used for univariate and multivariate analyses to investigate the influencing factors for COVID-19 after matching. ResultsThere were 87 patients in the UDCA group and 237 patients in the control group， and after PSM， there were 78 patients in the UDCA group and 137 patients in the control group， with good balance between the two groups. There was a significant difference in SARS-CoV-2 infection rate between the UDCA group and the control group ［82.1% （64/78） vs 95.6% （131/137）， χ2=10.847， P=0.001］. After COVID-19， compared with the control group， the UDCA group had a significantly lower proportion of the patients with chill （10.9% vs 38.9%， χ2=16.124， P<0.001） and cough （56.3% vs 74.8%， χ2=6.889， P=0.009）. There was a significant difference between the UDCA group and the control group in the proportion of the patients with a recovery time of ≤7 days after COVID-19 （79.7% vs 61.1%， χ2=6.760， P=0.009）. Both univariate and multivariate logistic regression analyses showed that UDCA was an independent influencing factor for COVID-19 （odds ratio=0.21 and 0.17， both P<0.05）. ConclusionUDCA is an protective factor against COVID-19 in patients with chronic hepatitis B and can alleviate related symptoms to some extent and shorten the recovery time， and therefore， it has an important value in the prevention and treatment of COVID-19.

OBJECTIVES@#To study the clinical and genetic features of Joubert syndrome (JS) in children.@*METHODS@#A retrospective analysis was performed on the clinical data, genetic data, and follow-up data of 20 children who were diagnosed with JS in the Department of Children's Rehabilitation, the Third Affiliated Hospital of Zhengzhou University, from January 2017 to July 2022.@*RESULTS@#Among the 20 children with JS, there were 11 boys and 9 girls. The common clinical manifestations were developmental delay (20 children, 100%), abnormal eye movement (19 children, 95%), and hypotonia (16 children, 80%), followed by abnormal respiratory rhythm in 5 children (25%) and unusual facies (including prominent forehead, low-set ears, and triangular mouth) in 3 children (15%), and no limb deformity was observed. All 20 children (100%) had the typical "molar tooth sign" and "midline cleft syndrome" on head images, and 6 children (30%) had abnormal eye examination results. Genetic testing was performed on 7 children and revealed 6 pathogenic genes, i.e., the CPLANE1, RPGRIP1L, MKS1, CC2D2A, CEP120, and AHI1 genes.@*CONCLUSIONS@#For children with developmental delay, especially those with abnormal eye movement and hypotonia, it is recommended to perform a head imaging examination to determine the presence or absence of "molar tooth sign" and "midline cleft syndrome", so as to screen for JS to avoid missed diagnosis and misdiagnosis. There are many pathogenic genes for JS, and whole-exome sequencing can assist in the diagnosis of JS.

Risk Factors Analysis and Prevention Strategy of Renke Space Edema Complicated with Vocal Cord Adhesion After CO2 Laser Resection / 中山大学学报(医学科学版)

ObjectiveTo investigate the prevention strategy of bilateral vocal cord adhesion after simultaneous Renke space edema resection under CO2 laser. MethodsSeventy patients who underwent CO2 laser resection of bilateral Renke space edema of vocal cords from June 2018 to June 2021 in our hospital were retrospectively selected for this study. According to their postoperative vocal cord adhesion， patients were divided into vocal cord adhesion group （35 cases） and silent band adhesion group （35 cases）， and the general data of the two groups were compared. Multivariate logistic regression analysis was used to evaluate the risk factors for postoperative vocal cord adhesion. The prediction model of postoperative morbidity risk of vocal cord adhesion was established by using chisquared automatic interaction detection （CHAID） classification tree algorithm， and the application value of the model was evaluated by benefit graph and index graph. ResultsMultivariate analysis showed that surgical range and depth of Ⅱ， laser power≥5 W and anterior connection involvement were the risk factors for postoperative vocal cord adhesion ［OR 95%CI： 6.113 （2.346， 17.451）； 5.214 （1.469， 15.263）； 18.651 （1.689， 36.203）］. The classification tree model showed that anterior articulation involvement was an important predictor of postoperative vocal cord adhesion （76.92%； χ2=11.993， P=0.001）， and the benefit graph and index graph showed good models. ConclusionClinical attention should be paid to surgical scope and depth， laser power and anterior union involvement， and timely prevention strategies should be formulated to reduce the risk of vocal cord adhesion in patients.

Mechanism of VPS26 gene promoting implant osseointegration through Wnt/β-catenin pathway in hyperlipidemia rats / 中华口腔医学杂志

Objective: To investigate the mechanism of VPS26 effect on osteogenesis and adipogenesis differentiation of rat bone marrow mesenchymal stem cells (BMSC) in high fat environment, and to explore the effect of VPS26 on implants osseointegration of high fat rats and ectopic osteogenesis in nude mice. Methods: BMSC were cultured under normal osteogenic induction (osteogenic group) and high-fat osteogenic induction (high-fat group).High-fat group was transfected with VPS26 enhancer and inhibitor, and the expression levels of osteogenesis related genes and adipogenesis related genes were examined. Osteogenesis and adipogenesis of BMSC were detected by alkaline phosphatase (ALP) staining and oil red O staining after 7 and 14 days of induction.In osteogenic group,the binding of VPS26 to β-catenin was detected by immunofluorescence staining and immunoprecipitation, and dual luciferase reporter assay (TOP Flash) was used to analyze the TOP/FOP ratio. Eighteen male 12-week hyperlipidemic Wista rats (160-200 g) were implanted with implants, and six in each group were injected with VPS26 overexpression lentivirus (LV-VPS26 group), negative control lentivirus (LV-nc group) and saline (blank control group).Micro-CT analysis , HE and oil red O staining were used to evaluate the osseointegration of the implants and lipid droplets formation of the femur samples. Twenty female 6-week nude mice (30-40 g) were divided into five groups and subcutaneously implanted with osteogenic BMSC non-transfected and transfected LV-VPS26, LV-nc, shVPS26, and shscr lentivirus on the back. Samples were used to observe ectopic osteogenesis. Results: The mRNA expression levels of ALP in the high-fat group BMSC after overexpression of VPS26 (1.56±0.09) were significantly higher than those of the negative control (1.01±0.03) (t=10.09, P<0.001), while those of peroxisome proliferator-activated receptor-γ (PPAR-γ) (t=6.44, P<0.001) and fatty acid-binding protein4 (FABP4) (t=10.01, P<0.001) were lower than those of the negative control. Western blotting results showed that compared with the negative control, protein expression of ALP and Runt-related transcription gene 2 was enhanced in the high-fat group BMSC after overexpression of VPS26 while PPAR-γ and FABP4 were inhibited. ALP activity of BMSC in the high-fat group was stronger after overexpression of VPS26, and the formation of lipid droplets was weaker than that in negative control. The results of immunofluorescence, immunoprecipitation and dual luciferase reporter assays showed co-localization and interaction of VPS26 with β-catenin and a significant 43.10% increase in the TOP/FOP ratio (t=-3.17, P=0.034). VPS26 overexpression enhanced osseointegration and decreased the number of lipid droplets in high-fat rat and enhanced ectopic osteogenesis of nude mice. Conclusions: VPS26 activated osteogenesis differentiation and inhibited adipogenic differentiation of BMSCs through Wnt/β-catenin pathway, promoting osseointegration of high-fat rat implants and ectopic osteogenesis of nude mice.

Clinical and genetic characteristics of children with dopa-responsive dystonia caused by tyrosine hydroxylase gene variations / 中华儿科杂志

Objective: To explore the clinical and genetic characteristics of children with dopa-responsive dystonia (DRD) caused by tyrosine hydroxylase (TH) gene variations. Methods: Clinical data of 9 children with DRD caused by TH gene variations diagnosed in the Department of Children Rehabilitation, the Third Affiliated Hospital of Zhengzhou University from January 2017 to August 2022 were retrospectively collected and analyzed, including the general conditions, clinical manifestations, laboratory tests, gene variations and follow-up data. Results: Of the 9 children with DRD caused by TH gene variations, 3 were males and 6 were females. The age at diagnosis was 12.0 (8.0, 15.0) months. The initial symptoms of the 8 severe patients were motor delay or degression. Clinical symptoms of the severe patients included motor delay (8 cases), truncal hypotonia (8 cases), limb muscle hypotonia (7 cases), hypokinesia (6 cases), decreased facial expression (4 cases), tremor (3 cases), limb dystonia (3 cases), diurnal fluctuation (2 cases), ptosis (2 cases), limb muscle hypertonia (1 case) and drooling (1 case). The initial symptom of the very severe patient was motor delay. Clinical symptoms of the very severe patient included motor delay, truncal hypotonia, oculogyric crises, status dystonicus, hypokinesia, decreased facial expression, and decreased sleep. Eleven TH gene variants were found, including 5 missense variants, 3 splice site variants, 2 nonsense variants, and 1 insertion variant, as well as 2 novel variants (c.941C>A (p.T314K), c.316_317insCGT (p.F106delinsSF)). Nine patients were followed up for 40 (29, 43) months, and no one was lost to follow-up. Seven of the 8 severe patients were treated by levodopa and benserazide hydrochloride tablets and 1 severe patient was treated by levodopa tablets. All the severe patients responded well to levodopa and benserazide hydrochloride tablets or levodopa tablets. Although the weight of the patients increased and the drug dosage was not increased, the curative effect remained stable and there was no obvious adverse reaction. One severe patient developed dyskinesia in the early stage of treatment with levodopa and benserazide hydrochloride tablets and it disappeared after oral administration of benzhexol hydrochloride tablets. Until the last follow-up, motor development of 7 severe patients returned to normal and 1 severe patient still had motor delay due to receiving levodopa and benserazide hydrochloride tablets for only 2 months. The very severe patient was extremely sensitive to levodopa and benserazide hydrochloride tablets and no improvement was observed in this patient. Conclusions: Most of the DRD caused by TH gene variations are severe form. The clinical manifestations are varied and easily misdiagnosed. Patients of the severe patients responded well to levodopa and benserazide hydrochloride tablets or levodopa tablets, and it takes a long time before full effects of treatment become established. Long-term effect is stable without increasing the drug dosage, and no obvious side effect is observed.

Different processed products of Polygonati Rhizoma treat Alzheimer's disease in rats: urine metabolomics based on UPLC-Q/TOF-MS / 中国中药杂志

The study investigated the effects of different processed products of Polygonati Rhizoma(black bean-processed Polygonati Rhizoma, BBPR; stewed Polygonati Rhizoma, SPR) on the urinary metabolites in a rat model of Alzheimer's disease(AD). Sixty SPF-grade male SD rats were randomized into a control group, a model group, a donepezil group, a BBPR group, and a SPR group, with twelve rats in each group. Other groups except the control group were administrated with D-galactose injection(100 mg·kg~(-1)) once a day for seven weeks. The control group was administrated with an equal volume of normal saline once a day for seven consecutive weeks. After three weeks of D-galactose injection, bilateral hippocampal Aβ_(25-35) injections were performed for modeling. The rats were administrated with corresponding drugs(10 mL·kg~(-1)) by gavage since week 2, and the rats in the model and control group with an equal volume of double distilled water once a day for 35 continuous days. The memory behaviour and pathological changes in the hippocampal tissue were observed. The untargeted metabolites in the urine were detected by ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry(UPLC-Q/TOF-MS). Principal component analysis(PCA) and orthogonal partial least square-discriminant analysis(OPLS-DA) were employed to characterize and screen differential metabolites and potential biomarkers, for which the metabolic pathway enrichment analysis was conducted. The results indicated that BBPR and SPR increased the new object recognition index, shortened the escape latency, and increased the times of crossing the platform of AD rats in the Morris water maze test. The results of hematoxylin-eosin(HE) staining showed that the cells in the hippocampal tissue of the drug administration groups were closely arranged. Moreover, the drugs reduced the content of interleukin-6(IL-6, P<0.01) and tumor necrosis factor-α(TNF-α) in the hippocampal tissue, which were more obvious in the BBPR group(P<0.05). After screening, 15 potential biomarkers were identified, involving two metabolic pathways: dicoumarol pathway and piroxicam pathway. BBPR and SPR may alleviate AD by regulating the metabolism of dicoumarol and piroxicam.

It is necessary to formulate the dietary guidelines for school aged children on the basis of the dietary guidelines for the general population, and revise in time according to the changes in the nutritional health status of school aged children. The revision of the dietary guidelines for school aged children is based on the content of Dietary Guidelines for Chinese School aged Children (2016). In addition, according to the revision principles and procedures of the Dietary Guidelines for Chinese Residents, as well as comprehensive consideration of the current prominent dietary and nutritional problems of school aged children in China, Dietary Guidelines for Chinese School aged Children (2022) is finally issued after evidence based researches, discussion and consultation. Dietary Guidelines for Chinese School aged Children (2022) highlights the improvement of nutritional literacy, the cultivation of healthy eating behaviors, the building of healthy food environment, as well as updating the recommendation concerning diet and active physical activity. Dietary pagodas for school aged children of different three ages including 6-10 years, 11-13 years and 14-17 years are added to the guideline. The Guideline provides practical references for parents, teachers, school health workers, medical staff in child health services and workers in centers for disease control and prevention.

Role of microRNA-132 and Mecp2 in methamphetamine dependence / 中国药理学通报

Aim To explore the roles of miRNA-132 and its related proteins(Mecp2, CREB)in the mechanism of methamphetamine(MA)-induced neurotoxicity and dependence.Methods The rats were intraperitioneally injected(ip)with MA(10 mg·kg-1·d-1)to establish methamphetamine dependence model with different dependent time courses of 1 week, 2 weeks, and 4 weeks respectively.The miRNA-132 and Mecp2 mRNA were detected by RT-qPCR, and the Mecp2, p-Mecp2, CREB and p-CREB proteins were detected by Western blot in the tissues of frontal cortex and hippocampus.Results In the frontal cortex, the miRNA-132 and Mecp2 mRNA were up-regulated in MA-dependent groups(P<0.05 and P<0.01), while the Mecp2 protein were down-regulated(P<0.01).MA could promote the phosphorylation of Mecp2 protein in the frontal cortex(P<0.01).In hippocampus, the miRNA-132 was down-regulated in the MA-dependent groups, but Mecp2 mRNA was up-regulated(P<0.05).Mecp2 protein increased in MA-dependent 1 week group(P<0.05), and then recovered with the prolonged time of MA dependence, then decreased in MA-dependent 4 weeks groups(P<0.05)in hippocampus.The phosphorylation level of Mecp2 was significantly decreased in the 1 week group(P<0.01), and then increased in the 2 weeks group(P<0.01)in hippocampus.Conclusions MA could induce an abnormal expression of miRNA-132 in the frontal cortex and hippocampus, and miRNA-132 might inhibit the translation of Mecp2 mRNA and induce the decrease expression of Mecp2 protein in the frontal cortex.But in hippocampus, miRNA-132 does not show the correlation with the Mecp2 expression trend of the frontal cortex.And miRNA-132 regulation does not depend on the expression of Mecp2 in hippocampus.

Clinicopathological features and prognosis of immunoglobulin A nephropathy after renal transplantation / 中华器官移植杂志

Objective:To summarize the relationship between the clinicopathological features and prognosis of immunoglobulin A nephropathy (IgAN) after renal transplantation.Methods:A total of 34 patients with IgAN after renal transplantation confirmed by renal biopsy were enrolled. And another 34 patients with primary IgAN confirmed by initial renal biopsy were adopted as controls. Clinical and pathological features of two groups were compared to explore the relationship between clinicopathological features and prognosis of allograft IgAN.Results:As compared with primary IgAN group, renal function in allograft IgAN group included serum creatinine [(158.5±75.9) vs (84.8±26.8) umol/L], urea nitrogen [(9.7±6.1) vs (5.2±1.4) mmol/L], uric acid [(406.7±87.8) vs (359.0±92.6) umol/L], estimated glomerular filtration rate {(57.4±25.4) vs (91.2±28.6) [ml/(min·1.73m 2)]}. All were statistically significantly higher ( P<0.05) while other parameters showed no differences. Pathologically, the proportion of T1 type (50.0% vs 17.6%) of renal tubular atrophy/interstitial fibrosis was significantly higher in allograft IgAN group than control group ( P<0.05). Furthermore, univariate and multivariate Logistic regression analyses were performed between various pathological parameters and prognosis in allograft IgAN patients. It indicated that the degree of mesangial hyperplasia of patients with transplanted IgAN had a significantly negative impact on the prognosis. Conclusions:The clinicopathological features of patients with allograft IgAN show no difference from those of patients with primary IgAN. And among patients with allograft IgAN, those with severe mesangial hyperplasia often have a worse prognosis.

OBJECTIVE@#To investigate the nutritional status of children with cerebral palsy (CP) and the clinical effectiveness of Subjective Global Nutritional Assessment (SGNA) in nutritional assessment of hospitalized children with CP.@*METHODS@#A total of 208 children with CP, aged 1-5 years, who were hospitalized from April to October 2019 were enrolled as subjects. SGNA was used to investigate nutritional status, and the Z-score method recommended by the World Health Organization was used as a reference standard to validate the clinical effectiveness of SGNA.@*RESULTS@#The detection rate of malnutrition in children with CP was 42.3% by SGNA and 39.4% by the Z-score method (P>0.05). The application of SGNA showed high consistency between different evaluators (κ=0.621, P<0.001). With the Z-score method as the reference standard, SGNA had a sensitivity of 80.5%, a specificity of 82.5%, a positive predictive value of 75.0%, and a negative predictive value of 86.7%, and high consistency was observed between the two evaluation methods (κ=0.622, P<0.001). SGNA was moderately consistent with weight-for-age Z-score and height-for-age Z-score (κ=0.495 and 0.478 respectively, P<0.001) and was poorly consistent with weight-for-height Z-score (κ=0.197, P<0.05).@*CONCLUSIONS@#There is a relatively high incidence rate of malnutrition in children with CP. SGNA can be used as a tool to assess the nutritional status of children with CP.

Discovery and study on potential effect of herbal pair of Uncariae Ramulus cum Uncis-Eucommiae Cortex on pregnancy hypertension based on network pharmacology and molecular docking / 中国中药杂志

This study aimed to explore the optimal indications and mechanism of Uncariae Ramulus cum Uncis(UR)-Eucommiae Cortex(EC) in lowering blood pressure based on network pharmacology and molecular docking. Chemical constituents were collected and screened by TCMSP database. Swiss Target Prediction platform was used to predict the related targets of the drug. OMIM, TCMIP and GeneCards databases were used to collect hypertension-related genes, and the intersections were taken to obtain potential targets for anti-hypertensive treatment of UR-EC. FunRich software was used to enrich the clinical phenotype and expression site of potential target of lowering blood pressure to analyze and predict the optimal indications of UR-EC. STRING database was used for KEGG pathway enrichment analysis, and Cytoscape 3.7.2 was used to construct the network of "composition-target-pathway". The key targets and their corresponding components in the network were analyzed and obtained, and then molecular docking was applied for preliminary verification. Twenty potential active components of UR and 24 potential active components of EC were respectively collected, and 92 anti-hypertensive potential targets of UR-EC were obtained. According to FunRich enrichment results, the optimal indication of UR-EC was pregnancy hypertension, which involved calcium signaling pathway, HIF-1 signaling pathway, neuroactive ligand receptor interaction, renin vascular tightening, VEGF signaling pathway, etc. In addition, AKT1, NOS2, ADRB2, F2, NOS3, SCN5 A, HTR2 A and JAK2 were considered as the key targets in the network. The molecular docking results showed that the screened potential active components had high binding activity with the key targets. This study preliminarily revealed that UR-EC may have therapeutic effects on pregnancy hypertension in terms of sedation, anti-hypertension, anti-inflammatory, anti-oxidation, improvement of vascular endothelial function and so on.
