Intestinal Cckbr-specific knockout mouse as a novel model of salt-sensitive hypertension via sodium over-absorption / 老年心脏病学杂志（英文版）

OBJECTIVES@#To investigate the value of CCKBRfl/fl villin-Cre mice as a mouse model of salt-sensitive hypertension (SSH).@*METHODS@#In the first part, 2-month-old CCKBRfl/fl villin-Cre mice (CKO) and control CCKBRfl/fl mice (WT) were fed with normal diet (0.4% NaCl) or high salt diet (4% NaCl), separately for 6 weeks. In the rescue study, one week of hydrochlorothiazide or saline injection were treated with the CKO mice fed high salt diet. The blood pressure, biochemical indexes, and the expression of small intestinal sodium transporters (NHE3, NKCC1, eNaC) was detected. The organ injury markers (MMP2/MMP9) and the histopathological changes of kidneys were observed, whereas the changes of duodenal sodium absorption were detected by small intestinal perfusion in vivo.@*RESULTS@#The CCKBRfl/fl villin-Cre mice with high salt intake exhibited high blood pressure, increased duodenal sodium absorption and urinary sodium excretion, and with renal injury. The protein expression of NHE3, NKCC1 and eNaC were also significant increase in the intestine of CKO-HS mice. Treatment with hydrochlorothiazide remarkably attenuated the elevated blood pressure by high salt absorption in the CCKBRfl/fl villin-Cre mice, but no significant histopathological changes were observed.@*CONCLUSIONS@#These results support a crucial role of intestinal Cckbr deficiency on SSH development and the diuretic antihypertension effect in CCKBRfl/fl villin-Cre mice. The CCKBRfl/fl villin-Cre mice with the high salt intake may serve as a stable model of salt-sensitive hypertensive induced by sodium overloading.

Impact of Smoke-Free Legislation on Acute Myocardial Infarction and Subtypes of Stroke Incidence in Shenzhen, China, 2012-2016: An Interrupted Time Series Analysis / 生物医学与环境科学（英文）

OBJECTIVE@#This study assesses the impact of smoke-free legislation on the incidence rate for acute myocardial infarction (AMI) and stroke in Shenzhen.@*METHODS@#Data on ischemic ( n = 72,945) and hemorrhagic ( n = 18,659) stroke and AMI ( n = 17,431) incidence covering about 12 million people in Shenzhen from 2012 to 2016 were used. Immediate and gradual changes in incidence rates were analyzed using segmented Poisson regression.@*RESULTS@#Following the smoke-free legislation, a 9% (95% CI: 3%-15%) immediate reduction was observed in AMI incidence, especially in men (8%, 95% CI: 1%-14%) and in those aged 65 years and older (17%, 95% CI: 9%-25%). The gradual annual benefits were observed only in hemorrhagic and ischemic stroke incidence, with a 7% (95% CI: 2%-11%) and 6% (95% CI: 4%-8%) decrease per year, respectively. This health effect extended gradually to the 50-64 age group. In addition, neither the immediate nor gradual decrease in stroke and AMI incidence rates did not show statistical significance among the 35-49 age group ( P > 0.05).@*CONCLUSION@#Smoke-free legislation was enforced well in Shenzhen, which would generate good experiences for other cities to enact and enforce smoke-free laws. This study also provided more evidence of the health benefits of smoke-free laws on stroke and AMI.

@#Objective    To evaluate the effectiveness and safety of a central venous catheter for thoracic drainage after video-assisted thoracoscopic lobectomy compared with a conventional chest tube. Methods    This study collected 200 patients with lung cancer who underwent thoracoscopic lobectomy and systematic hilar and mediastinal lymph node dissection between January 2018 and September 2019 in our hospital. The patients were randomly divided into two groups, including a group A (left with 28F chest tubes postoperatively) and a group B (left with 12G central venous catheters postoperatively). Patients in both groups were left with 2 chest tubes after upper lobectomy and 1 chest tube after middle or lower lobectomy. Duration and total volume of drainage, length of hospital stay, maximum visual analogue scale score and so forth were compared between the two groups. Results    Finally, 151 patients were included for analysis. There were 73 patients in the group A, including 26 males and 47 females, with an average age of 55.38±9.95 years, and 78 patients in the group B, including 37 males and 41 females, with an average age of 59.86±10.18 years. No statistical  difference was found between the two groups in drainage volume on postoperative day 2, and proportion of prolonged air leaks, hemothorax, chylothorax or drain reinsertion (all P>0.05). There was a statistical difference in drainage volume on postoperative day 1 [200.0 (120.0, 280.0) mL vs. 57.5 (10.0, 157.5) mL, P=0.000], postoperative day 3 [155.0 (100.0, 210.0) mL vs. 150.0 (80.0, 215.0) mL, P=0.023], total volume of drainage [890.0 (597.5, 1 530.0) mL vs. 512.5 (302.5, 786.3) mL, P=0.000], maximum pain score (2.29±0.72 points vs. 2.09±0.51 points, P=0.013) and length of hospital stay [7 (7, 9) d vs. 5 (4, 7) d, P=0.000]. Conclusion    Compared with conventional chest tubes, central venous catheters for chest drainage in patients with lung cancer after thoracoscopic lobectomy shortens the length of hospital stay and reduces postoperative pain.

Molecular Mechanism Analysis of Dengzhan Shengmai Capsules Against Chronic Cerebral Hypoperfusion / 中国实验方剂学杂志

ObjectiveBased on the protective effect of Dengzhan Shengmai capsules （DZSM） on chronic cerebral hypoperfusion （CCH）， network pharmacology was employed to investigate the molecular mechanism. MethodCCH model was established by right common carotid artery ligation. The mice were divided into sham operation group， model group， ginaton group （48 mg·kg-1）， DZSM low- and high-dose groups （0.040 5， 0.162 g·kg-1）. The efficacy was evaluated by the Morris water maze test and open-field test. The underlying mechanism of DZSM for CCH was analyzed by network pharmacology and verified by molecular biology experiments. PubChem， GeneCards， Metascape and other databases were used for targets collection and enrichment analysis. Besides， the association of ingredients targets of DZSM with disease targets of CCH， core target network and chemical components-core targets-pathways network were constructed by STRING 11.0 and Cytoscape 3.7.1. ResultThe escape latency of CCH mice significantly shortened on the 3rd to 5th day after DZSM low-dose treatment， the crossing times， time spent in the target quadrant， movement distance and distance in the central region of CCH mice significantly increased after DZSM low-dose and high-dose treatment. The results of network pharmacology indicated that DZSM might play a key role by regulating inflammatory response， phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway， cytokine-cytokine receptor interaction， tumor necrosis factor （TNF） signaling pathway， blood circulation， angiogenesis， extracellular matrix and other related biological processes and pathways， and acting as targets such as interleukin-6 （IL-6）， TNF， insulin-like growth factor 1 （IGF1）， vascular endothelial growth factor A （VEGFA）， epidermal growth factor （EGF）. The results of biological experiments showed that DZSM could reduce the expression of IL-6 in brain tissue of CCH mice. ConclusionDZSM provides a protective effect during CCH， and its multi-component， multi-pathway， multi-target mechanism is also revealed， which provides a basis for further study of the mechanism.

Automated Framework and Visualization-based Analysis of Concept Evolution of Spleen and Stomach Diseases and Syndromes in Traditional Chinese Medicine / 中国实验方剂学杂志

ObjectiveTo collect and screen records concerning the spleen and stomach diseases and syndromes in ancient books of traditional Chinese medicine （TCM） using an automated framework and to systematically explore the concept evolution of spleen and stomach diseases and syndromes using the visualization method. MethodA total of 1 224 kinds of ancient book data in the Ancient Books of Traditional Chinese Medicine Database （V2.1） were analyzed using the automated testing tool Selenium WebDriver with the Python 3.8 programming language and the etree library of Lxml for automatic collection and statistics of the "book title" "author" "classification" "dynasty" "completion time"， and "informative abstract". After being checked and collated， the collected data were visually analyzed with Tableau （V2020.1.3） for figuring out the concept evolution of spleen and stomach diseases and syndromes in the past dynasties from the perspectives of symptoms and signs， etiology and pathogenesis， principle-method-recipe-medicinal， and prognosis. ResultA total of 7 203 clauses were automatically collected from 989 ancient books. It was found that in the pre-Qin period， there were few ancient books related to the spleen and stomach diseases and syndromes， and the understandings were confined to the superficial symptoms or signs and the basic etiology and pathogenesis. From the Han to Sui and Tang dynasties， the related concepts gradually increased and the descriptions about the manifestations are more detailed than those in previous dynasties. The etiology， diagnosis， and treatment system of the spleen and stomach diseases and syndromes were further perfected. In the Song， Jin， and Yuan dynasties， such concepts as independent signs，symptoms， as well as nature and location of spleen and stomach diseases and syndromes were enriched. In the Ming and Qing dynasties， a TCM syndrome differentiation and treatment system for spleen and stomach diseases and syndromes was formed， and the related concepts were gradually simplified and unified. ConclusionThe concepts of spleen and stomach diseases and syndromes have undergone an evolution from simplicity to complexity and then back to simplicity. There are numerous ancient books discussing the concepts of spleen and stomach diseases and syndromes， exhibiting a fluctuating yet rising trend with time. The automated framework enables the construction of a lightweight database of spleen and stomach diseases and syndromes. Based on data visualization， the concept evolution of the spleen and stomach diseases and syndromes from ancient times to the present has been efficiently uncovered， which is conducive to tracing the origin and development of spleen and stomach diseases and syndromes in TCM. This has provided reference for related research of spleen and stomach diseases in modern Chinese medicine.

Research Status and Comparison on Medicinal Plants of Callerya and Millettia in China / 中国实验方剂学杂志

The Leguminosae perennial vines of Callerya and Millettia have many species and wide distribution， not only can be used for medicines， but also they have ornamental and insecticidal effects. With increasing demand for Spatholobi Caulis， and the reserves of wild medicinal materials are on the verge of exhaustion， resulting in the increasing number of mixtures and substitutes in the market， which makes it urgent to study the origin of Spatholobi Caulis. By referring to related literature， there are three major origins of Spatholobi Caulis， including Callerya， Millettia and Spatholobus. Callerya is separated from Millettia， they are divided and united for many times， now the official website of Flora of China has accepted the revision of them as two genera. This paper intends to compare the chemical components and pharmacodynamic effects of Callerya and Millettia， aiming to explore the similarities and differences between the two genera， so as to determine the rationality and necessity of separating Callerya from Millettia. After comparing， it was found that the chemical composition and pharmacodynamic effects of the two genera were different， which supported the separation of Callerya from Millettia， and it was not recommended to mix use of them.

Single-nucleus transcriptomic landscape of primate hippocampal aging

The hippocampus plays a crucial role in learning and memory, and its progressive deterioration with age is functionally linked to a variety of human neurodegenerative diseases. Yet a systematic profiling of the aging effects on various hippocampal cell types in primates is still missing. Here, we reported a variety of new aging-associated phenotypic changes of the primate hippocampus. These include, in particular, increased DNA damage and heterochromatin erosion with time, alongside loss of proteostasis and elevated inflammation. To understand their cellular and molecular causes, we established the first single-nucleus transcriptomic atlas of primate hippocampal aging. Among the 12 identified cell types, neural transiently amplifying progenitor cell (TAPC) and microglia were most affected by aging. In-depth dissection of gene-expression dynamics revealed impaired TAPC division and compromised neuronal function along the neurogenesis trajectory; additionally elevated pro-inflammatory responses in the aged microglia and oligodendrocyte, as well as dysregulated coagulation pathways in the aged endothelial cells may contribute to a hostile microenvironment for neurogenesis. This rich resource for understanding primate hippocampal aging may provide potential diagnostic biomarkers and therapeutic interventions against age-related neurodegenerative diseases.

Suitable soil moisture contents for water use efficiency and saponins accumulation in Panax notoginseng / 中草药·英文版

Objective: The moisture content in the soil directly affects the yield and quality of Panax notoginseng, especially at the age of three years old. However, the suitable moisture for the growth of P. notoginseng is unknown. In this study, the effects of different soil moisture on the growth of P. notoginseng were studied. Methods: Four different water treatments (0.45 field capacity (FC), 0.60 FC, 0.70 FC, and 0.85 FC) were set up in Shilin County, Yunnan Province, China. The water consumption and daily dynamic of water consumption were determined daily (from April 21 to October 18, 2012), and the daily dynamic of water consumption under different weather conditions (sunny and rainy) was determined. The transpiration coefficient and water use efficiency were calculated through dry matter accumulation and total water consumption. Accumulation of saponins of roots of P. notoginseng were analyzed by HPLC after treated, and the soil moisture content suitable for the growth of P. notoginseng was estimated by regression fitting of the active ingredient accumulation and the soil moisture content. Results: The water consumption of 0.85 FC, 0.70 FC, 0.60 FC and 0.45 FC were 2.89, 3.68, 3.37 and 2.73 kg/plant per day, respectively. The water consumption of P. notoginseng from June to August was greater than other months. The daily dynamic of water consumption on sunny days and sunny days after rain showed a “double peak” feature, and it showed a “single peak” feature on rainy days. The water uses efficiency (WUE) of 0.85 FC, 0.70 FC, 0.60 FC and 0.45 FC were 2.51, 3.32, 4.59, 3.39 gDW/kg H

miR-532-3p inhibits the progression of tongue squamous cell carcinoma by targeting podoplanin / 中华医学杂志(英文版)

BACKGROUND@#The association between miR-532-3p and tongue squamous cell carcinoma (TSCC) has been examined in the literature to improve the survival rate of patients with this tumor. However, further studies are needed to confirm the regulatory roles of this microRNA (miRNA) in TSCC. The objective of this study was to investigate the roles played by and the underlying mechanism used by the miR-532-3p/podoplanin (PDPN) axis in TSCC development.@*METHODS@#Western blotting and quantitative real-time reverse transcription-polymerase chain reaction (RT-qPCR) were performed to evaluate the PDPN expression level in TSCC tissues and cells. The proliferative, adhesive, and migratory capabilities of TSCC cells (CAL-27 and CTSC-3) were examined using cell counting kit-8 (CCK-8), cell adhesion, and wound-healing assays, respectively. The dual-luciferase reporter (DLR) assay was later conducted to confirm the relationship between miR-532-3p and PDPN.@*RESULTS@#The results indicated that PDPN expression was enriched in TSCC tissues and cells, and that the expression of PDPN was associated with some clinicopathological parameters of TSCC, including lymph node metastasis (P = 0.001), tumor-node-metastasis (TNM) staging (P = 0.010), and grading (P = 0.010). Further analysis also showed that PDPN knockdown inhibited the viability, adhesive ability, and migratory capacity of CAL-27 and CTSC-3 cells, effects that could be reversed by the application of a miR-532-3p inhibitor. Additionally, PDPN was found to be a direct target of miR-532-3p.@*CONCLUSIONS@#This research suggested that by targeting PDPN, miR-532-3p could inhibit cell proliferation viability, adhesion, and migration in TSCC. Findings also revealed that the miR-532-3p/PDPN axis might provide more insights into the prognosis and treatment of TSCC.

Correlation of circulating tumor DNA EGFR mutation levels with clinical outcomes in patients with advanced lung adenocarcinoma / 中华医学杂志(英文版)

BACKGROUND@#Circulating tumor DNA (ctDNA) is a promising biomarker for non-invasive epidermal growth factor receptor mutations (EGFRm) detection in lung cancer patients, but existing methods have limitations in sensitivity and availability. In this study, we used the ΔCt value (mutant cycle threshold [Ct] value-internal control Ct value) generated during the polymerase chain reaction (PCR) assay to convert super-amplification-refractory mutation system (superARMS) from a qualitative method to a semi-quantitative method named reformed-superARMS (R-superARMS), and evaluated its performance in detecting EGFRm in plasma ctDNA in patients with advanced lung adenocarcinoma.@*METHODS@#A total of 41 pairs of tissues and plasma samples were obtained from lung adenocarcinoma patients who had known EGFRm in tumor tissue and were previously untreated. EGFRm in ctDNA was identified by using superARMS. Through making use of ΔCt value generated during the detection process of superARMS, we indirectly transform this qualitative detection method into a semi-quantitative PCR detection method, named R-superARMS. Both qualitative and quantitative analyses of the data were performed. Kaplan-Meier analysis was performed to estimate the progression-free survival (PFS) and overall survival (OS). Fisher exact test was used for categorical variables.@*RESULTS@#The concordance rate of EGFRm in tumor tissues and matched plasma samples was 68.3% (28/41). At baseline, EGFRm-positive patients were divided into two groups according to the cut-off ΔCt value of EGFRm set at 8.11. A significant difference in the median OS (mOS) between the two groups was observed (EGFRm ΔCt ≤8.11 vs. >8.11: not reached vs. 11.0 months; log-rank P = 0.024). Patients were divided into mutation clearance (MC) group and mutation incomplete clearance (MIC) group according to whether the ΔCt value of EGFRm test turned negative after 1 month of treatment. We found that there was also a significant difference in mOS (not reached vs. 10.4 months; log-rank P = 0.021) between MC group and MIC group. Although there was no significant difference in PFS between the two groups, the two curves were separated and the PFS of MC group tended to be higher than the MIC group (not reached vs. 27.5 months; log-rank P = 0.088). Furthermore, EGFRm-positive patients were divided into two groups according to the cut-off of the changes in ΔCt value of EGFRm after 1 month of treatment, which was set at 4.89. A significant difference in the mOS between the two groups was observed (change value of ΔCt >4.89 vs. ≤4.89: not reached vs. 11.0 months; log-rank P = 0.014).@*CONCLUSIONS@#Detecting EGFRm in ctDNA using R-superARMS can identify patients who are more likely sensitive to targeted therapy, reflect the molecular load of patients, and predict the therapeutic efficacy and clinical outcomes of patients.

The similarity evaluation shows that the similarity of 32 batches of A. membranaceus var. mongholicus samples was 0.688-0.993. Among them, the similarity of samples in Shanxi, Inner Mongolia, Ningxia is 0.688-0.993, 0.835-0.989, 0.934-0.988, respectively and the similarity of samples in Gansu is 0.729-0.876 except No. 25 sample. The results of CA show that the samples of A. membranaceus var. mongholicus can be grouped into four categories according to the production area except the No. 11 and No. 25 samples. The results of PCA indicate that 32 batches of A. membranaceus var. mongholicus samples can be clustered according to quality and origin, and the quality of A. membranaceus var. mongholicus in Inner Mongolia is the closest to the wild breed. The results of OPLS-DA indicate that there are six components that can distinguish the wild and domestic A. membranaceus var. mongholicus, which are malonylastragaloside Ⅰ, astragaloside Ⅰ, calycosin-7-O-β-D-glycoside-6″-O-malonate, calycosin-7-O-β-D-glycoside, formononetin-7-O-β-D-glycoside-6″-O-malonate, and astrapterocarpan-3-O-β-D-glycoside-6″-O-malonate. The established method can be used to analyze differences between A. membranaceus var. mongholicus origin and planting environment, and can provide references for the protection and replacement of wild A. membranaceus var. mongholicus resources, and the cultivation, processing and production of A. membranaceus var. mongholicus.
