ObjectiveTo observe the efficacy and safety of Fuzheng Huayu tablets （FHT） for treating pulmonary inflammation in patients with coronavirus disease 2019 （COVID-19）. MethodA total of 70（4 cases were lost to follow-up, and 66 cases were finally completed） COVID-19 patients were recruited from February 1 to April 15 in 2020. They were assigned to a control group （35 patients） and a FHT group （31 patients）. The patients in the control group received routine treatment alone and those in the FHT group received FHT in addition to routine treatment. The primary outcome was the ratio of patients showing improvement in chest computed tomographic manifestations after 14 days. The secondary outcome measures included remission rate or progression rate of critical illness， clinical remission rate of respiratory symptoms， routine blood examination， C-reactive protein （CPR） level， procalcitonin （PCT） level， and blood oxygen saturation （SPO2）. The safety was assessed based on liver and kidney functions and adverse events. ResultAfter the 14-day treatment， the ratio of patients showing improvement in the FHT group （100%） was higher than that in the control group （77.1%） （χ2=8.063，P<0.01）. The ratio of disease stages after treatment showed no significant difference between two groups. In the FHT group， the symptoms including cough， dyspnea， and fatigue were alleviated after treatment （P<0.01）. In the control group， the symptoms including fever， cough， and dyspnea were alleviated （P<0.01）， while the fatigue was not relieved after treatment. No significant difference was observed in the clinical symptoms between the two groups after treatment. After treatment， the FHT group showed decreased white blood cell （WBC） count and neutrophil-to-lymphocyte ratio （NLR） （P<0.01）， elevated platelet （PLT） level （P<0.05）， lowered CRP level （P<0.05）， and no significant difference in lymphocyte （LYM）， hemoglobin （Hb）， SPO2 or PCT level. The control group showed decreased NLR （P<0.05） and WBC count （P<0.01）， elevated PCT level （P<0.05）， and no significant change in LYM， Hb， PLT， SPO2 or CRP level after treatment. Furthermore， the FHT group had higher PLT level than the control group （P<0.05） after treatment， and other indicators had no significant differences between the two groups. The liver and kidney functions had no significant difference between the two groups after treatment. ConclusionFHT can safely promote the absorption of acute pulmonary inflammation in COVID-19 patients.

Surgical tracheoplasty for children with congenital tracheal stenosis undergoing previous balloon dilatation or tracheal metal stent placement: a series of 9 cases / 中华外科杂志

Objective: To examine the outcomes of Slide tracheoplasty for the children with severe congenital tracheal stenosis received previous repeated balloon dilatation or metal stent placement under endoscopy. Methods: A retrospective study was conducted in 9 children with congenital tracheal stenosis undergoing previous interventional therapy under tracheoscopy and later received Slide tracheoplasty due to obvious respiratory symptoms at Department of Cardiac Surgery, Qilu Children's Hospital of Shandong University between February 2017 and July 2021. There were 7 males and 2 females with a median age at operation of 72.4 months (range: 13.3 to 98.9 months), and the median weight was 19.0 kg (range: 9.0 to 33.0 kg). Among the 9 patients, 2 patients began to receive repeated balloon dilatation (more than 3 times) 17.8 and 51.8 months ago respectively. One patient received metal stents placement into the trachea for 4 days and the other 6 children for median 56.8 months (range: 21.6 to 74.2 months). Complete tracheal cartilage rings and long segmental stenosis were present. in all 9 children. Operative details and outcome measures, including the need for endoscopic airway intervention and mortality, were collected. Results: Slide tracheoplasty was performed in all cases. Two patients with repeated balloon dilatation had different thickness of tracheal wall, local scar hyperplasia and irregular lumen. Among them, 1 case had obvious local calcification of tracheal wall, which was difficult to suture. The metal stent in one patient with short time of placement was completely removed. However, only part of the metal stents could be removed due to the long placement time in the other 6 cases. There was no operative death in the 9 children. The median postoperative tracheal intubation time was 25.3 hours (range: 17.4 to 74.5 hours). A silicone stent was placed in the trachea of 1 child due to obvious respiratory symptoms. Follow-up of median 11 months (range: 1 to 23 months) showed that no death occurred after discharge and all children had basically normal activity tolerance with no obvious respiratory symptoms. Conclusions: Slide tracheoplasty is feasible for children undergoing prior balloon dilatation or metal stents placement. Previously repeated balloon dilatation or metal stent placement under endoscopy increased the difficulty of slide tracheoplasty, the metal stent could not be completely removed after a long time.

Determination of genome-wide DNA and total RNA methylation in rats with myocardial infarction by mass spectrometry / 药学学报

To detect the methylation level of genome-wide DNA and total RNA in the process of heart failure, we established the method of ultra-high performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) to observe the change and synchronization of methylation rate of myocardial infarction (MI) tissue and peripheral blood. Animal welfare and experimental process were in accordance with the regulations of the Animal Ethics Committee of Guangzhou Medical University. The rats with myocardial infarction were divided into three groups: 1st, 4th, and 8th week to simulate different levels of cardiac function. And they were euthanized at the same time to keep the same age. DNA and RNA were extracted from infarct marginal tissues and peripheral blood lymphocytes, and then decomposed into single nucleosides by enzymolysis. The methylation rate of DNA and RNA was measured and calculated quantitatively. The results showed a concordant methylation changes in tissue and blood, and the methylation level of genome-wide DNA and total RNA was increased after myocardial infarction in rats. In this study, we obtained the preliminary data of DNA and RNA methylation during the occurrence and development of heart failure, further indicating that epigenetic changes can be used as biomarkers for early diagnosis of heart failure.

Study on relationship between lncRNAs and circRNAs in tumor / 中国药理学通报

With the development of whole genome and transcrip-tome sequencing technologies, a growing body of long noncoding RNAs (lncRNAs) and circular RNAs (circRNAs) has been i-dentified and is receiving increasing attention. LncRNAs and circRNAs are non-protein encoding transcripts whose functions are crucial for advancing our comprehensive understanding of bi-ological processes in human health and diseases, specifically tumor. And there is a close relationship between circRNAs and lncRNAs in their origin and function. In this paper, we have re-viewed the recent advances of lncRNAs and circRNAs in tumor by focusing on their relationships, which may help to distinguish them and identify tumor biomarkers further.

MicroRNA Profiling of Transgenic Mice with Myocardial Overexpression of Nucleolin / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Nucleolin (NCL) is the most abundant RNA-binding protein in the cell nucleolus and plays an important role in chromatin stability, ribosome assembly, ribosomal RNA maturation, ribosomal DNA transcription, nucleocytoplasmic transport, and regulation of RNA stability and translation efficiency. In addition to its anti-apoptotic properties, the underlying mechanisms associated with NCL-related roles in different cellular processes remain unclear. In this study, the effect of NCL on microRNA (miRNA) expression was evaluated by generating transgenic mice with myocardial overexpression of NCL and by analyzing microarrays of mature and precursor miRNAs from mice.</p><p><b>METHODS</b>Using microinjection of alpha-MyHc clone 26-NCL plasmids, we generated transgenic mice with myocardial overexpression of NCL firstly, and then mature and precursor miRNAs expression profiles were analyzed in NCL transgenic mice (n = 3) and wild-type (WT) mice (n = 3) by miRNA microarrays. Statistical Package for the Social Sciences version 16.0 software (SPSS, Inc., Chicago, IL, USA) was used to perform Student's t-test, and statistical significance was determined at P < 0.05.</p><p><b>RESULTS</b>Several miRNAs were found to be differentially expressed, of which 11 were upregulated and 4 were downregulated in transgenic mice with myocardial overexpression of NCL compared to those in WT mice. Several differentially expressed miRNAs were subsequently confirmed and quantified by real-time quantitative reverse transcription-polymerase chain reaction. Bioinformatics analysis was used for the prediction of miRNA targets. Furthermore, in vitro experiments showed that NCL regulated miR-21 expression following hydrogen peroxide preconditioning.</p><p><b>CONCLUSIONS</b>Myocardial-protection mechanisms exerted by NCL might be mediated by the miRNAs identified in this study.</p>

MicroRNA expression profile in the process of cyclic mechanical stretch promoting C2C12 myogenesis / 中国组织工程研究

BACKGROUND:In recent years,the incidence of skeletal muscle injury becomes higher and higher,but the skeletal muscle repair ability is limited;therefore,studies on the molecular mechanism of skeletal muscle repair play a positive role in the treatment of skeletal muscle injury.OBJECTIVE:To explore the role of microRNA in skeletal muscle regeneration.METHODS:C2C12 myoblasts were cyclic stretched in vitro by the Flexercell-5000 flexible device,and the appropriate stretch condition which could induce myogenesis was selected.The microRNA expression alteration during mechanical stretch-induced myoblast myogenesis was explored using high-throughout sequencing,and the differentially expressed microRNAs were further studied by the bioinformatics analysis.RESULTS AND CONCLUSION:10％ deformation,0.125 Hz cyclic mechanical stretch could promote myoblast proliferation and increase MyoD and Myogenin expressions in C2C12 myoblasts.MicroRNA expression profile alteration,including the downregulated miR-500-3p/1934-5p/31-3p/378a-5p/3473b/331-3p/5097 and upregulated miR-340-5p/449c-Sp/1941-3p,were all involved in the stretch-mediated myoblast myogenesis,and the MAPK signal pathway seemed to participate in this process.These results suggest that the low frequency of the cyclic mechanical stretch can upregulate the expression levels of myogenic regulatory factors through the alteration of MicroRNA expression,further inducing myogenesis,which the MAPK signal pathway may be involved in.

Treatment of children with advanced-stage lymphoblastic lymphoma with pegaspargase

To evaluate the feasibility of Pegaspargase instead of L-asparaginase to treat children with advanced-stage lymphoblastic lymphoma [LBL] on the Berlin-Frankfurt-Munster [BFM]-95 protocol. Fifty-four newly diagnosed patients with stage III or IV LBL and without any treatment were enrolled in this study. Pegaspargase took place of L-asparaginase in BFM-95. The complications and treatment responses of patients treated on the BFM-95 protocol and modified BFM-95 protocol were then evaluated respectively. For LBL patients treated with BFM-95 protocol or modified BFM-95 protocol, the complete response, event-free survival, overall survival were similar. Stage 4 myelosuppression was the most common complication in both groups. Besides that, among 31 patients receiving modified BFM-95 protocol, coagulation defects were the most common complication. In contrast, anaphylactic reaction was the most common complication in the other 23 patients receiving BFM-95 protocol. Modified BFM-95 protocol is available to children with advanced-stage LBL with an equal outcome and enhances its compliance and decreases the incidence of anaphylactic reaction, compared to BFM-95 protocol. Coagulation defects are the major complication and tolerable in modified one
