RESUMO

Severe isolated tricuspid regurgitation following left-sided heart valve surgery appears a growing clinical concern. Due to elevated operational risk of redo-sternotomy operation, it brings upon poor prognosis and decreased quality of life for these patients, and technical challenges for cardiac surgeons as well. With the advancing of minimally invasive surgical theory and skills, Chinese cardiac surgeons are building up their own surgical experience with this patient population. However, there remains controversy about the optimal surgical timing and strategy for these high-risk patients. With the lack of recommendation from evidence-based medicine, it is necessary to learn from the pioneers' experience and contemplate on gains and losses in clinical practice, which would help to improve the safety and outcome of the procedure and to benefit these patients.

RESUMO

Objective: To examine the short-term outcomes of minimally invasive reoperation for severe tricuspid regurgitation after left-sided valve surgery. Methods: From January 2015 to December 2018, a total of 89 patients with severe tricuspid regurgitation after left-sided valve surgery received reoperation in Department of Cardiovascular Surgery, Zhongshan Hospital, Fudan University were included in this study. There were 21 males and 68 females, aging of (56.4±7.9) years (range: 41 to 74 years). The interval between previous left-sided valve surgery and tricuspid reoperation was (14.1±6.1) years (range: 4 to 33 years). A combination of multiple minimally invasive techniques were adopted, including endoscopy-assist right minithoracotomy approach, peripheral cannulation strategy with the vacuum-assist single venous drainage technique, heart beating technique, and temporary percutaneous pacemaker implantation, with a concomitant enhancement in preoperative right cardiac function optimization. Results: All patients received minimally invasive isolated tricuspid valve replacement (n=81) or tricuspid valve repair (n=8). After the application of multiple minimally invasive techniques, the operative mortality rate was only 3.4% (3/89). The causes of death were progressive right heart failure with multiorgan failure (n=1) and low cardiac output associated with postoperative bleeding (n=2). Regarding to the perioperative complications, renal replacement therapy rate was 5.6% (5/89), permanent pacemaker implantation rate was 1.1% (1/89), and the incidence of stroke was 0. Mechanical ventilation time was 24(24) hours, ICU stay time was 2.5 (3.0) days (M(Q(R))). During the short-term follow-up, there were no case of severe tricuspid regurgitation, 2 cases of moderate regurgitation, 4 cases of mild-to-moderate regurgitation. Conclusions: For severe tricuspid regurgitation after left-sided valve surgery, the advanced minimally invasive techniques can significantly reduce the operative mortality and morbidity. Minimally invasive bioprosthetic tricuspid valve replacement is a reliable alternative for severe tricuspid regurgitation after left-sided valve surgery.

RESUMO

Late tricuspid regurgitation after left-sided valve surgery can negatively affect long-term prognosis. The surgical timing and strategy of tricuspid valve reoperation will have important impact on the surgical outcomes. However, there is no clear recommendations of the surgical timing for this condition in the current guidelines. Generally, tricuspid valve reoperation should be performed before irreversible right heart failure occurs. Although tricuspid valve repair is the first choice for tricuspid regurgitation, bioprosthetic tricuspid valve replacement might be a reliable alternative when tricuspid leaflets have severe rheumatic damage or right ventricle and tricuspid annulus significantly dilate. Combined minimally invasive surgical techniques, including right minithoracotomy approach, accessing the right atrium directly through the pericardium with limited dissection, peripheral cannulation strategy with the vacuum-assist single venous drainage technique and heart beating technique, can significantly decrease the operative mortality and postoperative bleeding. With development of interventional therapy, transcatheter tricuspid valve repair or replacement may become alternatives for tricuspid regurgitation after left-sided valve surgery in the future.

RESUMO

OBJECTIVE: To elucidate whether long non-coding RNA (lncRNA) Bmncr could inhibit RANML-induced osteoclast differentiation, thus alleviating the progression of osteoporosis. MATERIALS AND METHODS: Expression level of lncRNA Bmncr at different stages of osteoclast differentiation was detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). After Bmncr overexpression or knockdown in RAW 264.7 cells, expression levels of osteoclast-related genes were detected. Bone marrow mesenchymal stem cells (BMMs) isolated from rats undergoing ovariectomy (OVX) were induced with RANKL (50 ng/mL) and M-CSF (50 ng/mL) for 120 h. TRAP staining was conducted to count the number of TRAP-positive osteoclasts containing more than three nuclei. Bone resorption area of bone fragments was quantitatively analyzed. Osteoporosis model in mice was established. Mice were subjected to MicroCT analyses for recording BMD and BV/TV. The expression level of lncRNA Bmncr in the marrow and spleen of osteoporosis mice was examined. RESULTS: LncRNA Bmncr was lowly expressed in the marrow and spleen of osteoporosis mice. Besides, Bmncr expression gradually downregulated during RANKL-induced in vitro osteoclast differentiation, reaching the lowest level at 72 h. The overexpression of Bmncr reduced the amount of osteoclasts, inhibited bone resorption capacity, and downregulated expression levels of Atp6v0d2, Acp5, Ctr, and Mmp9. Conversely, Bmncr knockdown obtained the opposite trends. CONCLUSIONS: LncRNA Bmncr inhibits RANKL-induced osteoclast differentiation, thus alleviating the progression of osteoporosis.

RESUMO

Portal vein thrombosis (PVT) is one of the serious complications in the decompensated stage of liver cirrhosis, which is often accompanied by the aggravation of liver cirrhosis and other complications and in severe cases; it may induce gastroesophageal variceal hemorrhage and endanger the lives of patients. Furthermore, the most common complication in decompensated stage of cirrhosis is history of gastroesophageal variceal hemorrhage and the formation of PVT that may be a risk factor to promote each other. Presently, there are guidelines for diagnosis and treatment of gastroesophageal variceal hemorrhage in liver cirrhosis, but there is still a lack of in-depth understanding of cirrhosis complicated with PVT. This paper summarizes advances in the study of gastroesophageal variceal hemorrhage complicated with PVT in liver cirrhosis in order to enhance the understanding of risk factors for diagnosis and treatment.

RESUMO

Objective: To evaluate the progress and influence factors of asymptomatic osteonecrosis of the femoral head(ONFH). Methods: MRI was performed on the contralateral hips of 174 patients with unilateral symptomatic ONFH who admitted at Department of Orthopaedics, the Second Affiliated Hospital of Xi'an Jiaotong University from January 2012 to December 2018. Eighty-three of 174 patients with unilateral ONFH were found suffering from contralateral ONFH(47.7%), of which 77 patients were followed up.There were 28 males and 49 females with age of 48.6 years (range: 21-73 years). The pathogenesis, ARCO classfication, areas and position of osteonecrosis were collected.Independent sample t test, χ(2) test, Fisher exact test, multivariate Logistic regression were used to analyze the potential influence factors. Results: Patients were followed up for 36.7 months. During the following up period, ARCO classification of 28 patients (36.4%) progressed.The progress of asymptomatic ONFH was not related to the gender, age and original ARCO classification, but related to the pathogenesis, position and area of osteonecrosis (all P<0.05). Conclusion: The progress of asymptomatic osteonecrosis is related to the pathogenesis, position and area of osteonecrosis,but most of asymptomatic ONFH will not progress.

RESUMO

OBJECTIVE: A previous study reported that glucose-regulated protein 94 (GRP94) is involved in mechanical stress-induced chondrocyte apoptosis; however, the underlying molecular mechanisms remain unknown. The present study aimed to investigate the post-transcriptional regulatory mechanism of microRNAs (miRs) in mechanical stress-induced chondrocyte apoptosis by targeting GRP94. MATERIALS AND METHODS: Annexin V-fluorescein isothiocyanate/propidium iodide (PI) staining was conducted to evaluate the apoptosis of chondrocytes. The mRNA and protein expression levels were measured by reverse transcription-quantitative polymerase chain reaction and Western blotting, respectively. The targeted genes were predicted using a bioinformatics tool and further investigated via a luciferase reporter assay. RESULTS: The results demonstrated that cyclic loading led to significant increases in GRP94 expression in chondrocytes; however, the expression levels of miR-150 were downregulated. Bioinformatics analysis and a luciferase reporter assay indicated that GRP94 was a direct target of miR-150, as the expression of GRP94 was dysregulated following transfection with miR-150 mimics or inhibitors. In addition, mechanical stress-induced chondrocyte apoptosis was suppressed by transfection with miR-150 mimics, while the protective effects of miR-150 mimics in this process were inhibited by GRP94 overexpression. CONCLUSIONS: MiR-150 upregulation suppressed mechanical stress-induced chondrocyte apoptosis; the underlying molecular mechanism may be mediated, at least partially, via the inhibition of GRP94 expression.

RESUMO

Objective: To investigate the effects of probiotics and synbiotics on inflammation and microbiota of acute colitis in mice. Methods: C57BL/6J mice were divided into 4 groups randomly. Each group had 10 mice and was given 2.5% dextran sulfate sodium (DSS) drinking water for 5 days other than the blank control group. Except for model control group, other two groups were administrated with probiotics and synbiotics, respectively. Probiotics was composed of Lactobacillus acidophilus, Lactobacillus rhamnosus and Bifidobacterium lactis, while synbiotics was composed of the aforementioned probiotics, inulin and galactooligosaccharide. Feces of different periods and mucosa samples were collected to analyze the differences of enteric flora by 16s rDNA sequencing. Results: (1) Pathological scores in probiotics group and synbiotics group were 5.40±2.79 and 7.25±2.87, respectively, which were significantly lower than those in the model control group with scores 27.00±7.94. Model control group, probiotics group and synbiotics group showed lower flora diversity, increased Bacteroides and decreased Faecalibacterium than blank control group. The mucosal microbiota was different from fecal flora in abundance and species for each group, and Mucispirillum was more common in mucosa. Conclusions: Probiotics and synbiotics alleviate the inflammation of acute colitis in mice. Imbalance of beneficial genera to harmful genera is the characteristic of acute colitis. Supplementation of probiotics and synbiotics contributes to regulating the balance of intestinal microbiota.

RESUMO

OBJECTIVE: To investigate whether craving and demographic factors to predict relapse in alcohol dependence. METHODS: This study was a prospective cohort study. From August 2017 to August 2018, 158 Han male inpatients who met the diagnositic and statistical manual disorders-fourth version(DSM-IV) alcohol dependence diagnostic criteria were recruited from three mental hospitals in China. The participants were interviewed at baseline and followed up by telephone after 3 months for assessment. The baseline assessment after the acute withdrawal period included demographic data and alcohol-related data, clinical institute withdrawal assessment-advanced revised (CIWA-Ar), withdrawal and cue-induced craving on visual analog scale (VAS), Michigan alcoholism screening test (MAST), self-rating anxiety scale (SAS), self-rating depression scale (SDS) and alcohol urge questionnaire (AUQ). According to the follow-up results, "relapse" was defined as the consumption of beverages containing ethanol at any time during the follow-up study, and "time to relapse" was defined as the number of days from the first drinking to the baseline. Whether relapse occurred and the time to relapse were the primary endpoints. Cox proportional hazard regression model was used to analyze the factors affecting the relapse of alcohol dependence. RESULTS: In the study, 158 alcohol dependence patients were finally included, age from 21 to 60 years, with the mean age of (40.31±9.14) years. The relapse rate was 63.7% three months after baseline assessment. According to Cox univariate analysis and multivariate analysis, the age (OR=0.975, P=0.030) and CIWA-Ar scores (OR=1.126, P=0.010) significantly predicted relapse. And there was no significant difference in education level, marital status, withdrawal and cue-induced craving on VAS, SAS and SDS between the relapse group and the non-relapse group (P>0.05). CONCLUSION: Age and severity of alcohol-dependent withdrawal symptoms during hospitalization are significantly related to relapse for alcohol in alcohol-dependent patients. To be exact, the older age is a protective factor, that is to say, the younger patients are prone to relapse, while the risk of relapse is raised by the higher severity of withdrawal symptoms. However, neither cue-induced nor withdrawal craving can predict relapse of alcohol-dependent patients.

RESUMO

Objective: To compare the advantages and disadvantages of total arterial revascularization (TAR) and conventional off-pump coronary artery bypass (OPCAB) grafting in patients with left ventricular dysfunction (LVD). Methods: Between January 2008 and March 2015, 76 patients who were scheduled to undergo selective OPCAB were selected for cardiac surgery in Zhongshan Hospital, Fudan University. The left ventricular ejection fraction of enrolled patients was less than 35%. Among those patients, 38 patients in TAR group underwent total arterial OPCAB with bilateral internal mammary artery, left and/or right radial artery, and another 38 patients in control group underwent conventional OPCAB with left internal mammary artery and great saphenous vein. The clinical data of all patients were collected. The follow-up was performed within 36 months. Results: There was no significant difference in preoperative clinical data between the two groups (all P>0.05). Additionally, there was no significant difference in the application rate of internal mammary artery, positive inotropic drugs and intra-aortic balloon pump (IABP) use between the two groups (all P>0.05). The operation time of TAR group was longer than that of control group [(278.3±31.2) min vs (196.7±19.1) min, P<0.01]. There was no significant difference in perioperative mortality between the two groups (5.3% vs 7.9%, P=0.64). The volume of operative drainage and blood transfusion in TAR group increased significantly at 24 hours after operation [(895.0±236.2) ml vs (585.4±172.5) ml, (656.3±84.4) ml vs (433.3±62.9) ml, both P<0.01]. There was no significant difference in perioperative complications such as heart, kidney and lung failure between the two groups (all P>0.05). At 12 months after operation, there were no significant differences in survival rate, cardiac death rate, angina recurrence, myocardial infarction, re-treatment rate of revascularization, re-hospitalization rate from cardiac insufficiency, graft patency rate, cardiac function and echocardiographic data between the two groups (all P>0.05). From 24 to 36 months after operation, all the above indexes in TAR group were better than those in control group except for echocardiographic data (all P<0.05). Conclusions: For LVD patients, the early clinical efficacy of the two surgical methods is similar, but for the long-term outcomes, the whole arterial OPCAB operation is obviously superior. However, the shortcomings of total arterial OPCAB are that operative drainage and the use of blood products increased significantly after operation.

RESUMO

Objective: To report on the two years outcome of Chinese multi-center study of the treatment of high risk non-calcified pure aortic regurgitation with transcatheter heart valve replacement (TAVR) using domestic made J-Valve™ system. Methods: The national multi-center clinical study of the treatment of high risk non-calcified pure aortic regurgitation with transcatheter heart valve replacement using domestic made J-Valve™ system was conducted during the period from April 2014 to July 2015. The follow-up time was up to 2 years. Forty-three cases with predominant aortic valve regurgitation were enrolled for transapical implantation of the J-Valve™ system from 3 Chinese centers, including 16 patients from Zhongshan Hospital, Fudan University, 23 patients from West China Hospital, Sichuan University, and 4 patients from Fuwai Cardiovascular Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. There were 30 males and 13 females in this cohort. The age of the patients was (74±6) years (range: 61 to 84 years). The patiens were all sympotmatic preoperatively. All patients were considered at prohibitive or high risk for surgical valve replacement (Logistic European System for Cardiac Operative Risk Evaluation of (25.5±5.3)%, range: 20.0% to 44.4%) after evaluation by an interdisciplinary heart team. Comprehensive clinical and echocardiographic assessments were scheduled before discharge and at 30 days, 12 months, and 24 months after the procedure. Results: One patients was converted to surgical aortic valve replacement (SAVR) due to valve embolism into the arch. The other 42 cases had J-Valve™ systems implanted successfully. One patient died from multi-organ disorder due to paravalvular leak (PVL) during perioperative period. There was no acute myocardial infarction, stroke or coronary obstruction during the perioperative period. The median follow-up time was 725 days (range: 6 to 1 082 days). There were 5 patients died during the 2 years, follow-up, 2 patients had stroke, 2 patients had permanent pacemaker implanted. Three patients had valve related reinterventions: One for intraoperative valve embolism into the aortic arch followed by a conversion to SAVR which was mentioned above. One patient underwent SAVR on the postoperative day 6 due to moderate PVL and ventricular dysfunction. One patient underwent SAVR 6 months after primary procedure due to prosthesis thrombosis and severe aortic valve stenosis.Thirty-six patients with J-valve™ implanted survived to the latest echocardiogram follow-up, 25 patients had trivial or less PVL, 9 patients had mild PVL, and the transvalvular gradient after valve implantation was favorable at (9.8±5.8) mmHg (1 mmHg=0.133 kPa). Conclusions: Transapical implantation of domestic made J-Valve™ transcatheter heart valve system for patients with predominant aortic regurgitation has a excellent early outcome. This novel technology is safe and effective.

RESUMO

Objective:This study was aimed to compare the long-term effects of house dust mite (HDM) subcutaneous immunotherapy (SCIT) in a cohort of Chinese pediatric and adult patients with allergic rhinitis (AR).Method:Total of 48 AR patients received standardized HDM-SCIT for 3 years, and they received 3 years of standardized dust mite-specific subcutaneous immunotherapy, followed by 2 years after treatment. Prior to treatment (baseline) and at the end of the 3-year and 5-year treatment periods, all patients were evaluated for total nasal symptom scores(TNSS),total combined score (TCS;symptoms(nasal+ocular)+daily medication score),and rhinoconjunctivitis quality of life questionnaire(RQLQ).Safety of HDM-SCIT was assessed according to adverse events reported.Result:Fifteen pediatric and 33 adult AR patients completed the study.HDM-SCIT significantly improved symptoms and RQLQ scores at the 3 rd year and 5th year in both children and adults. Superior efficacy was observed at the 3-year and 5-year timepoints in children compared to adults. The safety of HDM-SCIT was comparable in children and adults with AR.Conclusion:A 3-year course of HDM-SCIT is an effective, safe and sustainable long-term treatment in both pediatric patients and adults with AR, although children appear to achieve better long-term efficacy compared to the adults.

RESUMO

Objective:The aim was to assess the prevalence of sensitized inhalant allergens in patients with allergic rhinitis (AR), analyze the differences of aeroallergen sensitization rates (SRs) in different areas, and define the minimal number and the type of aeroallergens required to identify patients as sensitized. Method:Six thousand two hundred and eighty five patients suffering from AR symptoms in Beijing, Heilongjiang, Inner Mongolia, Hebei and Shandong areas underwent standardized skin prick test (SPT) with 20 common aeroallergens during the period from Jan 2011 to Jul 2013 when seeking medical help in Beijing Tongren Hospital. The differences of aeroallergen sensitization rates in different areas were compared. Chi square was used in statistical analysis. Conditional approach allowed to determine the aeroallergen selection. Result:Among the 6 285 self-reported AR patients investigated, 5 575 (88.7%) patients had at least one positive skin prick reaction. The most common aeroallergen in Beijing, Heilongjiang, Hebei and Shandongwere house dust mites (HDMs). SRs of HDMs in these four areas decreased with latitude increment, whereas SRs of mugwort, ragweed and dandelion in these four areas increased with latitude increment. The three most prevalent aeroallergens in Inner Mongolia were mugwort (59.86%), ragweed (47.62%) and dandelion (46.26%), respectively. Overall, 8 allergens allowed identification ≥95% of sensitized subjects in Beijing. Conclusion:Der f was the most prevalent allergen in patients with AR in Beijing, Heilongjiang, Hebei and Shandong Areas, whereas SR of mugwort was highest in Inner Mongolia. Sensitization pattern of aeroallergens varied with areas. Eight allergens allowed identification of the majority of sensitized subjects in screening panels for allergy in Beijing.

RESUMO

Macrolides are a type of antibiotics with macrocyclic lactone ring, which have been commonly used in the treatment of diffuse panbronchiolitis, chronic obstructive pulmonary disease, bronchial asthma, cystic fibrosis and other diseases. Macrolides not only have effect on antibacterial, but also effect on anti-inflammatory and immunoregulation. Chronic rhinosinusitis (CRS) is a common disease entity of infectious and inflammatory diseases that involved in nasal cavity and nasal sinuses, with various clinical phenotypes. With the high prevalence of CRS, it seriously affects the quality of patients' life. In recent years, a large number of studies have shown that long-term low-dose macrolides are effective in parts of patients with CRS. Although the mechanism of macrolides for CRS has not yet been clarified. According to recent studies, it might be related with anti-inflammatory or immunoregulation of macrolides and the different phenotypes of CRS. The safety and mechanism of long-term macrolides are needed further clarification.
