Postoperative subacute static progressive stretch does not increase the risk of distal lower limb venous thromboembolism / 中华创伤杂志(英文版)

PURPOSE@#Static progressive stretch (SPS) can be applied to treat chronic joint stiffness. However, the impacts of subacute application of SPS to the distal lower limbs, where deep vein thrombosis (DVT) is common, on venous thromboembolism remain unclear. This study aims to explore the risk of venous thromboembolism events following subacute application of SPS.@*METHODS@#A retrospective cohort study was conducted on patients diagnosed with DVT following a lower extremity orthopedic surgery before being transferred to the rehabilitation ward from May 2017 to May 2022. Patients with unilateral lower limb comminuted para-articular fractures, transferred to rehabilitation ward for further treatment within 3 weeks after operation, followed up more than 12 weeks since initial manual physiotherapy, and diagnosed DVT by ultrasound before rehabilitation course were included in the study. Patients with polytrauma, without evidence of previous peripheral vascular disease or incompetence, had medication for thrombosis treatment or prophylaxis before the operation, detected with paralysis due to nervous system impairment, infected after operation during the regime, or with acute progression of DVT were excluded. The included patients were randomized to the standard physiotherapy and the SPS integrated groups for observation. Associated DVT and pulmonary embolism data were collected during the physiotherapy course to compare the groups. SSPS 28.0 and GraphPad Prism 9 were used for data processing. A p < 0.05 was set significant difference.@*RESULTS@#In total of 154 patients with DVT participating in this study, 75 of them were treated with additional SPS for postoperative rehabilitation. The participants in the SPS group showed improved range of motion (12.3° ± 6.7°). However, in the SPS group, there was no difference in thrombosis volume between the start and termination (p = 0.106, p = 0.787, respectively), although difference was seen intra-therapy (p < 0.001). Contingency analysis revealed the pulmonary embolism incidence (OR = 0.703) in the SPS group compared to the mean physiotherapy.@*CONCLUSION@#The SPS technique is a safe and reliable option to prevent potential joint stiffness without aggravating the risk of distal DVT for postoperative patients suffering from relevant trauma.

Vinegar-processed Euphorbiae Pekinensis Radix improves intestinal flora disorder and reduces colon toxicity / 中国中药杂志

The present study investigated the effect of Euphorbiae Pekinensis Radix(EPR) on intestinal flora structure before and after vinegar processing and explored the detoxification mechanism of vinegar-processed EPR. In this study, the extraction efficiency of casbane diterpenes from EPR with different solvents was investigated, and the optimal solvent was selected to enrich these components. After 14 days of intragastric administration of total diterpene extract of EPR and vinegar-processed EPR, 16 S rDNA sequencing technology was used to detect the structural changes of intestinal flora. The flora related to the intestinal toxicity of EPR was screened out based on the results of intestinal pathological damage by correlation analysis. The results showed that Soxhlet extraction with chloroform as extraction solvent could enrich Casbane diterpenes in EPR. As revealed by 16 S rDNA sequencing results, EPR could significantly change the structure of intestinal flora, which could be reversed by vinegar-processing EPR. Some intestinal flora candidates might be related to detoxification of vinegar processing. The correlation analysis of intestinal flora candidates and indexes related to intestinal mucosal injury showed that compared with EPR, vinegar-processed EPR could down-regulate the abundance of some pathogenic bacteria such as Mucispirillum, Bilophila, and Ruminiclostridium, and up-regulated some probiotics such as Enterorhabdus, Ruminococcaceae_UCG-014, Barnesiella, and Candidatus. The intestinal toxicity caused by EPR may be related to the disturbance of intestinal flora, and vinegar-processed EPR can improve intestinal flora disorder by up-regulating the abundance of probiotics and down-regulating the abundance of pathogenic bacteria to remodel the intestinal mucosal barrier and reduce toxicity.

Protection by microRNA-7a-5p Antagomir Against Intestinal Mucosal Injury Related to the JNK Pathway in TNBS-Induced Experimental Colitis.

BACKGROUND: Increasing evidence shows that microRNA-7a-5p (miR-7a-5p) plays an important role in regulating the inflammatory process in inflammatory bowel disease (IBD). How miR-7a-5p contributes to this process is poorly defined. The purpose of this study was to examine whether miR-7a-5p regulates 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced inflammatory responses via the JNK pathway. METHODS: Colitis was induced in male mice by intracolonic administration of TNBS; mice were divided into 3 groups: normal control (NC), TNBS, and miR-7a-5p antagomir-treated group. Inflammatory responses were estimated by disease activity index (DAI) and histological scores. The relative expressions of miR-7a-5p and tight junction protein, ZO-1, were detected by RT-qPCR. Western blot assays were used to estimate the level of JNK pathway proteins and ZO-1. After miRNA-antagomir injection, the extent of colonic tissue injury and expression levels of ZO-1 and JNK in intestinal tissue were compared. RESULTS: miR-7a-5p and p-JNK expression were higher in the intestinal tissue of the TNBS group as compared to NC. Inhibition of the expression of miR-7a-5p resulted in significantly decreased expression of p-JNK but increased expression of ZO-1 and promoted the recovery of intestinal mucosa. CONCLUSION: This work demonstrates a correlation between the JNK pathway and miR-7a-5p in TNBS-induced experimental colitis in mice, which may provide a new research direction for the treatment of IBD.

Effect of electroacupuncture on SIRT1/NF-κB signaling pathway in adipose tissue of obese rats / 中国针灸

OBJECTIVE@#To explore the effect of electroacupuncture (EA) on insulin sensitivity, adipose tissue inflammatory reaction and silent information regulation factor 1(SIRT1)/nuclear factor kappa B (NF-κB) signaling pathway in obese rats.@*METHODS@#A total of 100 SPF-grade Wistar male rats were collected. Thirteen rats of them were selected randomly as the normal group and fed with common forage, and the rest rats were fed with high-fat forage. Eight weeks later, 39 rats that met the obesity criteria were randomized into a model group, an EA group and a sham-EA group, 13 rats in each one. In each group, 3 rats were collected randomly and the hyperinsulinemic-euglycemic clamp was exerted to record glucose infusion rate (GIR) so as to determine insulin sensitivity. Afterwards, in the EA group, EA was applied to "Zusanli" (ST 36), "Fenglong" (ST 40), "Zhongwan" (CV 12) and "Guanyuan" (CV 4), stimulated with continuous wave, 2 Hz in frequency, 1 mA in current intensity, for 15 min. The treatment was given once every 2 days, 3 times a week, for 8 weeks totally. In the sham-EA group, the needles were inserted shallowly at the sites, 5 mm lateral to each of the acupoints stimulated in the EA group, and the electrodes were attached to the needle handles, but without electric stimulation exerted. The rest management was the same as the EA group. Before and after intervention, the body mass and the insulin sensitivity were measured. After intervention, the white adipose tissue was collected from the kidney in the rats. Western blot was adopted to detect the relative protein expressions of SIRT1, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and acetylated NF-κB (Ac-NFκB). The real-time fluorescence quantitative PCR was used to detect the mRNA expressions of SIRT1, IL-6 and TNF-α. The immunofluorescence double labeling method was applied to detect the co-expression of SIRT1 and Ac-NFκB in adipose tissue.@*RESULTS@#After fed with high-fat forage for 8 weeks, the body mass was significantly increased and GIR decreased in the rats of the model group as compared with the normal group (0.05). Compared with the normal group, in the model group, the protein and mRNA expressions of SIRT1 in adipose tissue were decreased, and the protein expression of Ac-NFκB increased, the protein and mRNA expressions of IL-6 and TNF-α increased (0.05). The results of immunofluorescence double labeling showed that SIRT1 and Ac-NFκB were co-expressed in adipose tissue.@*CONCLUSION@#Electroacupuncture significantly reduces the body mass, inflammatory reaction conditions of adipose tissue and improves insulin sensitivity in obese rats. Regarding the potential mechanism, after the activation of SIRT1/NF-κB signaling pathway by electroacupuncture, and down-regulates the transcription of downstream inflammatory factors.

MAFLD vs. NAFLD: shared features and potential changes in epidemiology, pathophysiology, diagnosis, and pharmacotherapy / 中华医学杂志(英文版)

Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease worldwide, placing an increasing burden on human health. NAFLD is a complex multifactorial disease involving genetic, metabolic, and environmental factors. It is closely associated with metabolic syndrome, obesity, and type 2 diabetes, of which insulin resistance is the main pathophysiological mechanism. Over the past few decades, investigation of the pathogenesis, diagnosis, and treatments has revealed different aspects of NAFLD, challenging the accuracy of definition and therapeutic strategy for the clinical practice. Recently, experts reach a consensus that NAFLD does not reflect the current knowledge, and metabolic (dysfunction) associated fatty liver disease (MAFLD) is suggested as a more appropriate term. The new definition puts increased emphasis on the important role of metabolic dysfunction in it. Herein, the shared features and potential changes in epidemiology, pathophysiology, diagnosis, and pharmacotherapy of the newly defined MAFLD, as compared with the formerly defined NAFLD, are reviewed for updating our understanding.

Objective To assess and compare the incidence,clinical characteristics,treatment,and prognosis of acute heart failure patients from different grades hospitals in Beijing.Methods In this prospective internet prognosis registered study (Beijing AHF Registry),a total of 3 335 consecutive patients admitted to 14 emergency departments in Beijing from January 1st 2011 to September 23rd 2012 were enrolled.According to hospital grade,these patients were divided into two groups,349 patients were from secondary hospitals,and 2 956 patients were from tertiary hospitals.Results Among the 3 335 patients,the medium age was 71 (58,79) years,and male accounted for 53.16％.The most common underlying disease were coronary disease (43.27％),hypertension (17.73％),cardiomyopathy (16.07％) etc.The average treatment time in Emergency Department was 66.82 h.The emergency department mortality rate was 3.81％ (127 cases).The 30-day and 1-year cumulative all-cause mortality were 15.3％ and 32.27％,respectively.The 30-day and 1-year cumulative all-cause readmission were 15.64％ and 46.89％,respectively.Compared with patients in tertiary hospitals,patients in secondary hospitals had more onset acute heart failure patients (63.64％ vs.49.93％),shorter emergency department treatment time (12 h vs.41 h),lower discharge rate (3.43％ vs.37.45％) and emergency department mortality(1.58％ vs.4.09％).Compared with those in tertiary hospitals,1-year cumulative all-cause mortality (25.6％ vs.33.2％),cardiovascular disease mortality (20.2％ vs.26.0％),aggravated heart failure mortality (22.4％ vs.28.8％) were lower in secondary hospitals.Following propensity score matching,compared to tertiary hospitals,patients in secondary hospitals showed lower utilization rate of beta-blockers and ACEFARB (4.51％ vs.28.17％,1.41％ vs.9.58％),except the pironolactone.Conclusion Acute heart failure in emergency department is associated with a high mortality rate and readmission rate.There is still a big gap between guidelines recommend medication current treatments for acute heart failure.

Effect of EP4 gene silencing on the growth and migration of papillary thyroid carcinoma K1 cells / 实用医学杂志

Objective To investigate the effect of EP4 gene silencing on the growth and migration of K1 cells. Methods K1 cells with stable knockdown of EP4 were constructed with lentiviral vector. QRT-PCR and western blot analysis were used to detect the expression of EP4 mRNA and protein in K1 cells. CCK8 assay and flow cytometry were employed to measure cell viability and apoptosis. Transwell assay was applied to detect cell migration. Results Compared with the negative control group,the mRNA and protein expression of EP4 were sig-nificantly decreased in K1 cells with stable knockdown of EP4. Furthermore,shRNA-mediated silencing of EP4 gene remarkably suppressed cell viability and induced apoptosis of K1 cells.The migration of K1 cells with knock-down of EP4 was decreased compared with the negative control group. Conclusions EP4 gene silencing can in-hibit growth and induce apoptosis of K1 cells.Downregulation of EP4 can significantly reduce migration of K1 cells.

Systematic review of the effectiveness of intratracheal injection of pulmonary surfactant in the treatment of neonatal respiratory distress syndrome / 临床儿科杂志

Objective To evaluate the effectiveness of intratracheal injection of pulmonary surfactant (LISA) combined with continuous positive airway pressure (CPAP) on the treatment of neonatal respiratory distress syndrome (RDS). Methods The databases of PubMed, EMBASE, Cochrane, China National Knowledge Infrastructure (CNKI), Wanfang Database, Weipu Database and China Biology Medicine disc (CBM) were searched, and all of the randomized controlled trial of LISA combined with CPAP for treatment of RDS were included. RevMan 5.2 was used to perform meta-analysis. The differences of mortality, bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP), intraventricular hemorrhage (IVH), periventricular leukomalacia (PVL), and other complications between LISA group and control group were compared in 0.05). Conclusion The mechanical ventilation and the incidence of BPD is significantly reduced in the treatment of neonatal respiratory distress syndrome by LISA, but it has no effect on the incidences of other complications and mortality.

Research report of the clinical application effect of Clampcath trocar in immune adsorption / 重庆医学

Objective To observe the application effect of Clampcath trocar in immune adsorption.Methods A tatol of 40 patients underwent immune adsorption in our hospital were divided into the observation group and the control group according to the random number table method,with 20 cases in each group.In the observation group,20 cases were treated with Clampcath trocar as temporary vascular access for immune adsorption,and in the control group,20 cases were treated with 16 G indwelling needle as temporary vascular access for immune adsorption.The blood flow,tube plugging rate,discount rate,indwelling time of immune adsorption of patients in each group were compared.Results The tube blocking rate and discount rate of the observation group were significantly lower than that of the control group (P＜0.05),the difference wasstatistically significant;in the observation group,the blood flow was significantly higher than that in the control group (P＜ 0.01),the indwelling time of the observation group was longer than that of the control group (P＜0.05),the difference was statistically significant.Conclusion Clampcath trocar could be used as temporary vascular access for immune adsorption,of which the operation is simple,and is cheap and affordable.Meanwhile,it has advantages include low tube plugging rate and discount rate,long indwelling time and sufficient blood flow,thus it could alleviate the suffering of patients and reduce the waste of resources,and it's worthy of clinical promotion.
