ABSTRACT

@#In addition to the typical respiratory symptoms, COVID-19 patients present with clinical manifestations of cardiovascular system damage, and they are at higher risk of intensive care or mortality. The mechanism of COVID-19's impact on the cardiovascular system is still unclear, therefore we need to pay close attention to it. Based on the existing research, this paper focused on the concurrent characteristics of the cardiovascular system diseases, summarized the possible mechanisms of cardiovascular system damage, including the coronavirus invaders directly into cardiomyocytes and its conduction system, with complications or accompanying conditions such as cytokine storm, imbalance of oxygen supply and demand, drug influence, stress and other damage to cardiovascular system. Meanwhile, current clinical manifestations and treatment methods of COVID-19 were summarized.

ABSTRACT

Retinal pigment epithelial (RPE) is primarily impaired in age-related macular degeneration (AMD), leading to progressive loss of photoreceptors and sometimes choroidal neovascularization (CNV). mTOR has been proposed as a promising therapeutic target, while the usage of its specific inhibitor, rapamycin, was greatly limited. To mediate the mTOR pathway in the retina by a noninvasive approach, we developed novel biomimetic nanocomplexes where rapamycin-loaded nanoparticles were coated with cell membrane derived from macrophages (termed as MRaNPs). Taking advantage of the macrophage-inherited property, intravenous injection of MRaNPs exhibited significantly enhanced accumulation in the CNV lesions, thereby increasing the local concentration of rapamycin. Consequently, MRaNPs effectively downregulated the mTOR pathway and attenuate angiogenesis in the eye. Particularly, MRaNPs also efficiently activated autophagy in the RPE, which was acknowledged to rescue RPE in response to deleterious stimuli. Overall, we design and prepare macrophage-disguised rapamycin nanocarriers and demonstrate the therapeutic advantages of employing biomimetic cell membrane materials for treatment of AMD.

ABSTRACT

Hepatic ischemia/reperfusion injury (HIRI) is a serious complication that occurs following shock and/or liver surgery. Gut microbiota and their metabolites are key upstream modulators of development of liver injury. Herein, we investigated the potential contribution of gut microbes to HIRI. Ischemia/reperfusion surgery was performed to establish a murine model of HIRI. 16S rRNA gene sequencing and metabolomics were used for microbial analysis. Transcriptomics and proteomics analysis were employed to study the host cell responses. Our results establish HIRI was significantly increased when surgery occurred in the evening (ZT12, 20:00) when compared with the morning (ZT0, 08:00); however, antibiotic pretreatment reduced this diurnal variation. The abundance of a microbial metabolite 3,4-dihydroxyphenylpropionic acid was significantly higher in ZT0 when compared with ZT12 in the gut and this compound significantly protected mice against HIRI. Furthermore, 3,4-dihydroxyphenylpropionic acid suppressed the macrophage pro-inflammatory response in vivo and in vitro. This metabolite inhibits histone deacetylase activity by reducing its phosphorylation. Histone deacetylase inhibition suppressed macrophage pro-inflammatory activation and diminished the diurnal variation of HIRI. Our findings revealed a novel protective microbial metabolite against HIRI in mice. The potential underlying mechanism was at least in part, via 3,4-dihydroxyphenylpropionic acid-dependent immune regulation and histone deacetylase (HDAC) inhibition in macrophages.

ABSTRACT

Cannulated Screw is a common internal fixation for the treatment of femoral neck fractures. However, the traditional implantation method has disadvantages such as inaccuracy and large radiation exposure. Based on the anatomical characteristics of the femoral neck and geometric principles, we develop a novel guide device for cannulated screws insertion. The cadaver experiment showed that it can improve the accuracy of cannulated screws implantation, reduce puncture attempts and the radiation exposure of doctors and patients.

ABSTRACT

Drug instructions,the statutory and technical documents recording effectiveness and safety information,are an important basis for guiding doctors,pharmacists,and patients to use drugs rationally,and their scientificity,standardization,and accuracy directly affect the medication safety of the public. The sections of adverse drug events,contraindications,precautions,warnings,and application for specific populations in drug instructions directly express safety information and measures for rational use of drugs. In the drug life cycle,marketing authorization holders( MAHs) need to update safety information in the instructions promptly to ensure the safety and effectiveness of clinical drug medication. At present,revising instructions is an important measure to control drug risks. In the drug life cycle,in order to standardize the revision of safety information in the instructions by MAHs and eliminate inexact terms such as " unclear",the Technical Specifications for Revision of Safety Information in Marketed Chinese Patent Medicine Instructions,a series of group standards,have been established under the guidance of Standardization Department,China Association of Chinese Medicine. Therefore,on the basis of the existing rules and regulations,the standardized technical procedures for revising instructions came into being to help clinical safe and rational medication of drugs,and implement the strategy of " Healthy China".

ABSTRACT

The abnormality of platelet function plays an important role in the pathogenesis and evolution of blood stasis syndrome (BSS). The explanation of its mechanism is a key scientific issue in the study of cardiovascular and cerebrovascular diseases and treatment. System biology technology provides a good technical platform for further development of platelet multi-omics, which is conducive to the scientific interpretation of the biological mechanism of BSS. The article summarized the pathogenesis of platelets in BSS, the mechanism of action of blood activating and stasis resolving drugs, and the application of genomics, proteomics, and metabonomics in platelet research, and put forward the concept of "plateletomics in BSS". Through the combination and cross-validation of multi-omics technology, it mainly focuses on the clinical and basic research of cardiovascular and cerebrovascular diseases; through the interactive verification of multi-omics technology and system biology, it mainly focuses on the platelet function and secretion system. The article systematically explains the molecular biological mechanism of platelet activation, aggregation, release, and other stages in the formation and development of BSS, and provides a new research idea and method for clarifying the pathogenesis of BSS and the mechanism of action of blood activating and stasis resolving drugs.

ABSTRACT

Objective:To investigate the therapeutic effect of Yanghe decoction combined with Tounongpowder on patients with acute plasma cell mastitis and its influence on inflammatory factors.Methods:A total of 120 patients with acute plasma cell mastitis admitted to Yantai Affiliated Hospital of Binzhou Medical College from May 2019 to May 2020 were selected, and divided into control group (60 cases) and combination group (60 cases). The control group was treated with western medicine, and the combination group was treated with Yanghe decoction and Tounongpowder on the basis of the control group. Seven days was 1 course and a total of 4 courses were continued. The scores of symptoms and signs and clinical effects of the two groups before treatment and 1 month after treatment were compared. The serum interleukin(IL)-1β and IL-6 were measured by radioimmunoassay, and tumor necrosis factor-α(TNF-α) was measured by enzyme-linked immunosorbent assay.Results:After 1 month of treatment, the scores of breast swelling, breast lumps, breast pain, breast fistula symptoms and signs in the two groups were significantly decreased, the scores of above index in the combination group were significantly lower than those in the control group, and the differences were statistically significant ( P<0.05). The total effective rate in the combined group was higher than that in control group: 91.7%(55/60) vs. 76.7% (46/60), and the difference was statistically significant ( χ2 = 8.456, P<0.05). After 1 month of treatment, the serum levels of IL-1β, IL-6 and TNF-α in the two groups were significantly reduced, and the serum levels of above 3 index in the combination group were significantly lower than those in the control group: (3.24 ± 0.92) ng/L vs. (3.81 ± 1.02) ng/L, (1.12 ± 0.42) ng/L vs. (1.41 ± 0.35) ng/L, (32.27 ± 19.03) ng/L vs. (43.04 ± 21.58) ng/L, and the differences were statistically significant ( P<0.05). After treatment, the liver and kidney functions of the two groups were not abnormal, and the differences in adverse reactions such as headache, dizziness, nausea and vomiting were not statistically significant ( P>0.05). Conclusions:Yanghe decoction combined with Tounongpowder can significantly improve the clinical symptoms of patients with acute plasma cell mastitis, with a definite clinical effect. Its mechanism of action may be related to reducing the levels of IL-1β, IL-6, and TNF-α and reducing the inflammatory response.

ABSTRACT

Objective:To evaluate the auxiliary diagnosis value of bacterial culture, polymerase chain reaction (PCR) and serum anti-pertussis toxin immunoglobulin G (AntiPT-IgG) level detection in suspected pertussis.Methods:A total of 110 suspected cases of pertussis treated in the Department of Pediatrics of Wuhu No.1 People′s Hospital from June 2018 to May 2019 were recruited for the study.The nasopharyngeal swabs of all cases were collected for Bordetella pertussis culture and specific nucleic acid PCR detection.Serum samples of 78 cases were collected for the detection of AntiPT-IgG level by enzyme linked immunosorbent assays.Results:The positive rates of bacterial culture group and PCR group were 21.8% and 30.0%, respectively, with no statistically significant difference ( χ2=1.198, P>0.05). The culture positive rate of cases with the duration of cough<2 weeks was 32.1%, which was signi-ficantly higher than that of cases with the duration of cough about 2-4 weeks (14.3%) or >4 weeks (9.1%) ( χ2=6.522, P<0.05). The PCR positive rate of cases with the duration of cough <2 weeks was 39.6%, which was also significantly higher than that of cases with the duration of cough about 2-4 weeks (25.7%) or > 4 weeks (13.6%) ( χ2=6.126, P<0.05). The mean value for serum AntiPT-IgG level of 78 cases was (75.727±78.454) IU/mL, the median AntiPT-IgG levels of cases with the duration of cough<2 weeks and about 2-4 weeks were 5.909 IU/mL and 20.948 IU/mL, respectively, and the positive rates were 14.7% and 38.1%, respectively.The AntiPT-IgG level of cases with the duration of cough> 4 weeks and that at convalescent stage were (79.281±68.254) IU/mL and (107.242±75.750) IU/mL, and the positive rates were 39.1% and 57.1%, respectively. Conclusions:In the vaccine era, the results of pathogenic and serological tests should be combined to assist the clinical diagnosis of pertussis.The positive rate of bacterial culture and specific nucleic acid pathogen detection in children with cough duration less than 2 weeks is high, and the serological diagnosis is more effective after the duration of cough is over 4 weeks.

ABSTRACT

Objective To observe the 24-week survival status of patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) treated with plasma exchange (PE) and double plasma molecular adsorption system (DPMAS) alone or in combination, and to establish a predictive model for 24-week prognosis. Methods Related clinical data were collected from 133 patients with HBV-ACLF who received PE and DPMAS alone or in combination in The Affiliated Provincial Hospital of Anhui Medical University from January 2015 to December 2019, and according to the survival status at the 24-week follow-up after treatment, they were divided into survival group with 71 patients and death group with 62 patients. A total of 55 patients with HBV-ACLF who received PE and DPMAS alone or in combination in The Second Affiliated Hospital of Anhui Medical University from January 2018 to January 2020 were enrolled as validation group to validate the performance of the model. Related clinical data included mode of artificial liver support therapy, age, sex, total bilirubin (TBil), international normalized ratio (INR), creatinine (Cr), serum sodium, platelet count (PLT), albumin (Alb), and presence or absence of ascites, hepatorenal syndrome, hepatic encephalopathy, and gastrointestinal bleeding. The t -test was used for comparison of normally distributed continuous data between two groups, and the Wilcoxon rank-sum test was used for comparison of continuous data with skewed distribution between two groups; the chi-square test and the Fisher's exact test were used for comparison of categorical data between groups. The Cox regression model was used to analyze the influencing factors for the prognosis of HBV-ACLF patients after PE and DPMAS alone or in combination and establish a predictive model; the receiver operator characteristic (ROC) curve was plotted and the DeLong method was used to compare the area under the ROC curve (AUC) between the new predictive model and Model for End-Stage Liver Disease (MELD)/MELD combined with serum sodium concentration (MELD-Na) scores. Results At 24 weeks after treatment, 71 patients survived and 62 patients died in the modeling group. The Cox regression analysis showed age (hazard ratio [ HR ]=1.030, P =0.013), TBil ( HR =1.018, P < 0.001), INR ( HR =1.517, P < 0.001), and PLT ( HR =0.993, P =0.04) were independent influencing factors for 24-week survival. According to the results of the Cox regression analysis, a prognostic model for HBV-ACLF patients treated with PE and DPMAS alone or in combination was established as ATIP=0.029×age (years)+0.018×TBil (mg/dL)+0.417×INR-0.007×PLT (10 9 /L). Both the modeling group and the validation group showed that the ATIP model had a better predictive performance than MELD and MELD-NA scores(all P < 0.05). Conclusion Age, TBil, INR, and PLT are independent influencing factors for the 24-week survival of HBV-ACLF patients treated with PE and DPMAS alone or in combination, and the ATIP model has a good performance in predicting the 24-week prognosis of HBV-ACLF patients treated with PE and DPMAS alone or in combination.

ABSTRACT

OBJECTIVE@#To explore the expression of CD40/CD40L in multiple myeloma(MM) patients and its influence on prognosis.@*METHODS@#Thirty patients with MM treated in Cangzhou People's Hospital from May 2016 to June 2017 were selected and divided into MM group, then 30 healthy people with a physical examination in our hospital at the same time were selected as the normal group. The serum CD40/CD40L levels of the patients in the two groups was detected by flow cytometry, and its correlation with the lymphocyte population, pathological grade and prognostic significance of MM patients was anaysis.@*RESULTS@#The expression of CD40 in serum of the patients in MM group was significantly higher than those in normal group (P0.05). The levels of CD40 and CD40L in the patients before and after chemotherapy showed no difference(P>0.05). The levels of Ts and NK cells in the patients of MM group were lower than those in normal group (P0.05). The CD40 level was correlated with the serum total B lymphocyte level of the patients in MM group (r=0.877, P=0.005). There was a correlation with CD40L and Th cells in the serum of MM patients (r=-0.783, P=0.035). The expression of serum CD40 in the patients at phase III-IV was higher than those of the patients at phase I-II, the levels of serum CD40L in MM patients at different periods showed no significant difference(P>0.05). The survival rate of MM patients with high CD40 expression was lower than that of MM patients with low CD40 expression (χ@*CONCLUSION@#The increasing of CD40 level in MM patients is related to the pathological grade of the patients. Chemotherapy can reduce the level of CD40. The increasing of CD40 is an important factor for the poor prognosis of MM patients. CD40L level is not meaningful for MM treatment and prognosis.

ABSTRACT

To explore the mechanism of Hedyotis Diffusae Herba-Smilacis Glabrae Rhizoma(HDH-SGR) in treating lung adenocarcinoma based on big data bioinformatics combined with network pharmacology analysis and molecular docking technology. The chemical components and potential therapeutic targets of HDH-SGR were obtained from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP). Lung adenocarcinoma-related genes were obtained from The Cancer Genome Atlas(TCGA), Therapeutic Target Database(TTD), Pharmacogenetics and Pharmacogenomics Knowledge Base(PharmGKB), Online Mendelian Inheritance in Man(OMIM), DrugBank, and GeneCards. "Drug component-target" network was constructed using Cytoscape to screen out key compounds. STRING was used to build protein-protein interaction(PPI) network and core targets were screened out by Cytoscape-CytoNCA topology analysis. Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) analyses of target genes were performed by R-clusterProfiler. Finally, key compounds were docked to core target genes using AutoDock. The results showed that 22 active compounds and 499 potential therapeutic targets were obtained from HDH-SGR. A total of 14 332 lung adenocarcinoma-related targets were screened out through six data platforms, including 182 common targets. Fifteen core targets were screened out from the PPI network. GO and KEGG analyses revealed significant enrichment of relevant target genes in various biological processes, cellular functions(e.g., response to lipopolysaccharide, nuclear receptor activity, and ligand-activated transcription factor activity) and close relationship between target genes and non-small cell lung cancer signaling pathways. Based on the results of molecular docking validation, diosgenin, quercetin, naringenin, taxifolin, 2-methoxy-3-methyl-9,10-anthraquinone, stigmasterol, and β-sitosterol were able to bind tightly to the core targets. HDH-SGR can intervene in lung adenocarcinoma through multiple targets and signaling pathways, such as non-small cell lung cancer signaling pathways. The binding of active components in Chinese medicine to key targets is presumedly one of the mechanisms that produce therapeutic effects.

ABSTRACT

Ischemic cardiovascular and cerebrovascular diseases threatening human health and survival have high morbidity and mortality. The common cause of them is reduced blood supply caused by vascular stenosis, atherosclerosis, and infarction. However,the pathological processes of ischemic cardiovascular and cerebrovascular diseases are complex, involving oxidative stress, calcium overload, inflammation, apoptosis, autophagy and other mechanisms. Protein drugs such as recombinant tissue plasminogen activator(rt-PA) and urokinase have been proved with excellent therapeutic effects and huge economic and social benefits in the clinical treatment and interventional therapy. Among them, peptide drugs have shown unique advantages and potential prospects owing to their strong biological activity, high target specificity, biochemical diversity, and low toxicity. Chinese medicinal materials, characterized by multi-component and multi-target therapy, have also shown excellent clinical efficacy against ischemic cardiovascular and cerebrovascular diseases. However, the research and development of related peptides in Chinese medicinal materials is at the initial stage. Therefore, this paper reviewed the targets and action mechanisms of a variety of Chinese medicinal material-derived polypeptides with activities against ischemic cardiovascular and cerebrovascular diseases, aiming to provide support for the in-depth research as well as the clinical development and application of these polypeptides.

ABSTRACT

The traditional Chinese medicine(TCM) syndrome of blood stasis refers to blood stagnation in meridians and viscera, with the main symptoms of pain, mass, bleeding, purple tongue, and unsmooth pulse. Cardiovascular and cerebrovascular diseases are among the major chronic diseases seriously harming the health of the Chinese. Among the coronary heart disease and stroke patients, most demonstrate the blood stasis syndrome. Platelet is considered to be one of the necessary factors in thrombosis, which closely relates to the TCM syndrome of blood stasis and the occurrence of cardiovascular and cerebrovascular diseases. The clinical and laboratory research on platelet activation and aggregation has been paid more and more attention. Its purpose is to treat and prevent blood stasis syndrome. In this study, the authors analyzed the research on the dysfunctions of platelets in blood stasis syndrome, biological basis of TCM blood stasis syndrome, and the effect of blood-activating stasis-resolving prescriptions on platelets, aiming at providing a reference for exploring the mechanism of platelet intervention in the treatment of TCM blood stasis syndrome and the pathways and targets of Chinese medicine in the prevention and treatment of the syndrome.

ABSTRACT

Objective:To analyze the risk factors for postoperative pulmonary venous obstruction after correction of total anomalous pulmonary venous connection(TAPVC).Methods:We retrospectively reviewed all patients undergoing operative repair of TAPVC in our institution from December 2013 to January 2018. Patients with functionally univentricular circulations or atrial isomerism were excluded. Patients were divided into two groups according to whether there was pulmonary vein obstruction. The clinical variables of the two groups were compared. Variables for the multivariable analysis were chosen if there was statistical significance on univariable analysis.Results:145 patients were included, 91(63%) males, aged 4(2, 8)months and weight 5.5(4.5, 7.5)kg. Mean follow-up interval was(51±23) months. Postoperative obstruction developed in 27 patients(18.6%). The differences of anatomic type[supracardiac 18(67%) vs.59(50%), cardiac 4(15%) vs. 50(42%), infracardiac 3(11%) vs. 1(1%), mixed 2(7%) vs. 8(7%), P=0.003], preoperative obstruction[yes 19(70%) vs. 37(31%), no 8(30%) vs. 81(69%), P<0.001], associated cardiac lesions[yes 13(48%) vs. 27(23%), no 14(52%) vs. 91(77%), P=0.008] and bypass time[109(89, 129)min vs. 88(70, 110)min, P=0.002] between two groups were statistical significant. A multivariable model showed preoperative obstruction( P<0.001) and bypass time( P=0.009) were associated with postoperative obstruction. Conclusion:The incidence of pulmonary vein obstruction after correction of TAPVC was still high. If there was preoperative obstruction, or the bypass time was too long during operation, the surveillance of pulmonary vein obstruction should be strengthened after operation.

ABSTRACT

Objective:This study aims to review two surgical techniques results of the reoperation for left atrioventricular valve(LAVV) failure in repaired atrioventricular septal defect.Methods:All consecutive patients with repaired atrioventricular septal defect(AVSD) who underwent redo-LAVV surgery from 2005 to 2019 were included. Patients with single ventricles, banding, atrial isomerism, and complex associated anomalies were excluded. Univariate analysis included repair and replacement. Data analyzed included number and year of primary AVSD and redo-LAVV operation, morphology of AVSD, mortality, and reoperation, early and long-term survival.Results:There were a total of 28 patients including 7 boys(25%) with age of 114.5 months(63.0-194.5 months). The mean body weight was 28.55 kg(15.5-55.9 kg). There were 11(39.3%) patients with complete AVSD and 17(60.7%) with partial AVSD, and 21(75%) patients with LAVV valvuloplasty(LAVVP), 7(25%) patients with LAVV replacement(LAVVR). The aortic cross clamp time was significantly longer in patients who underwent LAVVR compared to LAVVP[LAVVR 94 min(79-107)min vs. LAVVP 66 min(45-83 min), P<0.05]. The technique of cleft closure with LAVVP 18(87.5%) more than LAVVR 2(28.6%), P<0.05. Conclusion:The postoperative left atrio-ventricular valve(LAVV) regurgitation is the main reason of the reoperation. The technique of cleft closure with LVVR-Repair is favorable. At follow-up, survivors with re-LVVR-Repair have high rates with numerous operations.
