ABSTRACT

OBJECTIVES@#To explore the effect mechanism of electroacupuncture (EA) on functional constipation (FC) at the combined lower he-sea and front-mu points of large intestine based on enteric neuronal autophagy.@*METHODS@#A total of 40 SPF Kunming mice were randomly divided into 5 groups (n = 8), i.e. a control group, a model group, an acupuncture group, a 3-methyl adenine (3-MA) group, and a 3-MA + acupuncture group. Except the control group, the FC model was established by gavage with compound diphenoxylate suspension for 14 days in the other 4 groups. After successful modeling, the mice of the acupuncture group and the 3-MA + acupuncture group received EA at bilateral "Tianshu" (ST 25) and "Shangjuxu" (ST 37), stimulated for 30 min with disperse-dense wave, 2 Hz/15 Hz of frequency, 1 mA of intensity. EA was delivered once daily. One course of treatment was composed of 5 days and 2 courses were needed, with an interval of 2 days. An intraperitoneal injection of 3-MA (15 mg/kg) was administered 30 min before EA in the mice of the 3-MA group and the 3-MA + acupuncture group, once daily. Before and after intervention, the time of the first black stool defecation and defecation behaviors in 6 h were observed in each group. After intervention, in every group, the small intestine propulsion rate was calculated, the colon tissue morphology was observed using HE staining, the ultrastructure of enteric neuronal autophagy was observed under transmission electron microscope, and the expressions of microtubule-associated protein 1 light chain 3 (LC3), Beclin-1 and neuronal nuclear antigen protein (NeuN) in neurons of colonic muscularis were determined by immunohistochemistry.@*RESULTS@#Before intervention, when compared with those in the control group, the time of the first black stool defecation was prolonged (P<0.01, P<0.05), and numbers (P<0.01), wet weight (P<0.01, P<0.05) and water content (P<0.05, P<0.01) of stool in 6 h were reduced in the model, acupuncture, 3-MA and 3-MA + acupuncture groups. After intervention, compared with those in the control group, the time of the first black stool defecation was longer (P<0.05), and numbers (P<0.01), wet weight (P<0.01) and water content (P<0.01) of stool in 6 h were decreased in the model group. The time of the first black stool defecation was shortened (P<0.01), and numbers (P<0.01), wet weight (P<0.01) and water content (P<0.01) of stool in 6 h were increased in the acupuncture group when compared with those in the model group. The time of the first black stool defecation was extended (P<0.01), and numbers (P<0.01), wet weight (P<0.01) and water content (P<0.01) of stool in 6 h were declined in the 3-MA + acupuncture group in comparison with those in the acupuncture group. All layers of colon tissue were normal and intact in each group. When compared with the control group, the small intestine propulsion rate and the average optical density (OD) values of LC3, Beclin-1 and NeuN in neurons of colonic muscularis were decreased (P<0.01), and autophagosomes were dropped in the model group. In the acupuncture group, the small intestine propulsion rate and the average OD values of NeuN, LC3 and Beclin-1 in neurons of colonic muscularis increased (P<0.01,P<0.05), and autophagosomes were elevated when compared with those in the model group. The small intestine propulsion rate and the average OD values of NeuN, LC3 and Beclin-1 in neurons of colonic muscularis were dropped (P<0.05,P<0.01) in the 3-MA + acupuncture group in comparison with those in the acupuncture group.@*CONCLUSIONS@#Electroacupuncture may promote enteric neuronal autophagy and increase the number of neurons so that the intestinal motility can be improved and constipation symptoms can be relieved in FC mice.

ABSTRACT

In the systemic perspective, family is a system capable of self-organization, which possesses enough resources and ability to solve its own problems. To promote family health, the systemic therapists are required to consider each family member’s opinions and construction to certain problems, and assist them to discover and activate their own resources as well. Promoting family health also requires members to actively develop a sharing pattern within the family, exert the positive role of family rules, develop an authoritative parenting style so as to promote the mental health of children. Family members should ensure the clear and open boundaries between different subsystems, and maintain the stability of subsystem of the husband and wife especially. Furthermore, family members in different subsystems should make reasonable trade-offs and choices corresponding to different situations in order to both minimize conflicts and maintain the satisfying function of the family system. A healthy and ideal intimate relationship is interpreted from the systemic perspective of " evolvable, changeable, associative" on the core of " intimacy, passion and commitment" . The relationship will enhance partners' personal growth, in which the partners can not only examine its dynamic variations together but also deepen the understanding and acceptance of each other under the circumstances of bilateral original families and living environments. In addition, a healthy conjugal relationship has higher requirements such as " kinship" , commitment to two families of the couple and the children, and balancing the benefits between core family and original family.

ABSTRACT

Body image flexibility (BIF) is the specific type of psychological flexibility in the research field of body image, which reflects the ability to experience negative body image and related events in an open and acceptive way, and take actions consistent with one's values. Body image is actually not stable. If negative body image could not be adjusted effectively in time, it would develop into body image disturbance (BID), which is one of the core symptoms and psychopathological mechanisms of eating disorder (ED) and body dysmorphic disorder (BDD). BIF is one of the important factors in this development path, gaining more and more attention as a protective factor for body image. So far, most studies focus on eating disorder patients and related sub-clinical populations. Body image-acceptance and action questionnaire is the most widely used measurement. BIF is related to some sample characteristics, such as gender, age and body size.Cultural context also has an impact on it.Positive and negative body image and eating disorder pathological characteristics are also strongly associated with BIF. As to the intervention, the application of mindfulness, acceptance and compassion in treatment may improve BIF. Future studies need to improve the research methods and designs, and pay attention to other samples. More specific interventions need to be developed, of which the therapeutic mechanisms also need to be explored.

ABSTRACT

Objective:To compare the influence of single and staged percutaneous coronary intervention (PCI) on long-term prognosis in patients with multi-vessel coronary artery disease.Methods:Using prospective research methods, 1 832 patients with multi-vessel coronary artery disease from January to December 2013 in Fuwai Hospital, Chinese Academy of Medical Sciences were selected. According to the time of PCI, the patients were divided into single PCI group (1 218 cases) and staged PCI group (614 cases). The patients were followed up for 2 years, the primary endpoint was major cardiovascular and cerebrovascular event (MACCE), including target vessel-related myocardial infarction (TV-MI), target vessel-related revascularization (TVR), cardiogenic death and stroke, and the secondary endpoint was stent thrombosis. The propensity score matching (PSM) was applied to balance the discrepancies between 2 groups, and the baseline and follow-up data were compared. The Kaplan-Meier survival curves were drawn to evaluate the survival rates events; multifactor Cox proportional risk regression was used to analyze whether staged PCI was an independent risk factor for the endpoint events.Results:The in-hospital stay, duration of procedure and synergy between percutaneous coronary intervention with taxus and cardiac surgery (SYNTAX) score in single PCI group were significantly lower than those in staged PCI group: (5.54±3.09) d vs. (9.50±4.06) d, (43.12±28.55) min vs. (79.54±44.35) min, (14.04±7.63) scores vs. (18.51±7.79) scores, and there were statistical differences ( P<0.01); there were no statistical difference in complete revascularization rate and SYNTAX score after PCI between 2 groups ( P>0.05). Based on 2-year follow-up, the incidences of TV-MI and stent thrombosis in staged PCI group were significantly higher than those in single PCI group: 2.1% (13/614) vs. 0.5% (6/1 218) and 2.0% (12/614) vs. 0.4% (5/1 218), and there were statistical differences ( P<0.01). Kaplan-Meier survival curves analysis results showed that the event-free survival rates of TV-MI and stent thrombosis in single PCI group were better than those in staged PCI group (99.5% vs. 97.9% and 99.6% vs. 98.0%, P<0.01). Multifactor Cox proportional risk regression analysis results showed that staged PCI was an independent risk factor for stent thrombosis ( HR = 3.91, 95% CI 1.25 to 12.18, P = 0.019). After PSM, the incidences of TV-MI and stent thrombosis in staged PCI group were significantly higher than those in single PCI group: 2.1% (13/614) vs. 0.7% (4/614) and 2.0% (12/614) vs. 0.5% (3/614), and there were statistical differences ( P<0.05); Kaplan-Meier survival curve analysis results showed that the event-free survival rates of TV-MI and stent thrombosis in single PCI group were significantly higher than those in staged PCI group: (99.3% vs. 97.9% and 99.5% vs. 98.0%, P<0.05); multifactor Cox proportional risk regression analysis results showed that staged PCI was not an independent risk factor of stent thrombosis ( HR = 2.29, 95% CI 0.58 to 9.00, P = 0.234). Both before and after PSM, there were no evidences for interaction between the type of angina pectoris and staged PCI ( P>0.05). Conclusions:Although a seemingly increase exists in the incidence of TV-MI and stent thrombosis in the staged PCI group, staged PCI is an independent risk factor neither for MACCE and its components, nor for stent thrombosis. In addition single PCI reduces the in-hospital days and duration of PCI procedure, which may be a relatively reasonable approach to clinical practice.

ABSTRACT

Intervertebral disc degeneration (IDD) is an age-related degenerative disease and a major cause of low back pain. IDD greatly impairs the quality of life of patients and dramatically increases the economic burden of patient families. There are currently no effective intervention and treatment for IDD, partly due to a lack of understanding of its pathogenesis. The establishment and characterization of IDD animal models are critical for defining mechanisms underlying its pathogenesis. IDD is a complex process, which is affected by mechanical stress, injury, biochemistry and gene expression. In this review article, we summarize several IDD animal models generated by utilizing abnormal mechanical stress, injury, biochemical and chemical induction and gene knockout. Biomechanics play a key role in maintaining intervertebral disc homeostasis, and abnormal mechanical stress can cause IDD. Usually, IDD is accompanied by structural injury which exacerbates IDD. In addition, biochemical and chemical induction and knockout of key genes can also lead to IDD. Among the different factors causing abnormal mechanical stress, there are two mechanical stress models: pressure model and instability model. According to the structure of intervertebral disc, there are two structural injury models: the nucleus pulposus and annulus fibrosus injury model and the cartilage endplate injury model. The biochemical and chemical induction model and the gene knockout model are summarized, and the applications and limitations of different IDD animal models are discussed.

ABSTRACT

Eating disorder (ED) is a kind of chronic refractory mental disorder with high prevalence rate, high recurrence rate, high disability rate and heavy social burden.There is a close relationship between eating disorder and emotional regulation.More and more studies have shown that ED patients have abnormal emotional regulation.Emotional disorder is a feature of ED patients, and ED patients are easy to take abnormal eating ways to relieve their negative emotions.Studies have shown that the amygdala, ventral striatum (VS), nucleus accumbens (NAc), anterior cingulate cortex (ACC), prefrontal cortex (PFC) and subcallosal components (SCC) are crucial for emotion regulation and homeostasis.The structural and functional changes of these brain regions are closely related to emotional stimuli and impaired regulation in patients with ED.The purpose of this review is to summarize the neural mechanism of ED abnormal emotion regulation and discuss the future research direction.

ABSTRACT

With the development of society, eating disorders(EDs) have attracted people's attention because of their chronicity, high fatality rate and heavy social burden. However, the current treatment mainly includes psychotherapy and drug therapy, but the therapeutic effect is not satisfactory. Studies suggest that patients with EDs have brain abnormalities related to the prefrontal cortex. In recent years, the neuromodulation therapies, especially the non-invasive neuromodulation therapies, have become a research hotspot because of their few side effects and easy to use. At present, they have been used in mental disorders such as depression, obsessive-compulsive disorder, substance addiction and so on. A small number of studies on EDs have also been carried out. This paper reviews the related studies on anorexia nervosa and bulimia nervosa, and introduces the working principles of deep brain stimulation, transcranial magnetic stimulation and direct current stimulation and their efficacy in the treatment of EDs. Previous studies have shown that neuromodulation therapies are effective in the treatment of EDs. However, the existing research results are not exactly same, and the best parameters need to be clarified. In the future study, it is necessary to integrate cognitive, neuroimaging and biomarker data to identify different endophenotypes in EDs, so as to help clarify the disease mechanism, help patients with EDs to formulate individual treatment plans, improve clinical symptoms, and put forward suggestions and prospects for future research and application.

ABSTRACT

Directed evolution is a cyclic process that alternates between constructing different genes and screening functional gene variants. It has been widely used in optimization and analysis of DNA sequence, gene function and protein structure. It includes random gene libraries construction, gene expression in suitable hosts and mutant libraries screening. The key to construct gene library is the storage capacity and mutation diversity, to screen is high sensitivity and high throughput. This review discusses the latest advances in directed evolution. These new technologies greatly accelerate and simplify the traditional directional evolution process and promote the development of directed evolution.

ABSTRACT

Objective: To explore the related factors of premature acute myocardial infarction(AMI), and to compare the the long-term outcomes in patients with and without premature AMI after percutaneous coronary intervention (PCI). Methods: This study was a prospective cohort study.From January 2013 to December 2013, 10 724 consecutive patients with coronary heart disease undergoing PCI in Fuwai Hospital were enrolled. Among them 1 920 patients with the diagnosis of AMI were divided into two groups: premature AMI (man≤50 years old, woman≤60 years old) and non-premature AMI. The baseline characteristics were collected, and multivariate logistic regression was uesed to analysis the related factors of premature AMI. The clinical outcomes, including the major adverse cardiovascular and cerebrovascular events(MACCE) which was the composite of cardiac death, myocardial infarction, revascularization, stroke and stent thrombosis, as well as bleeding events, during hospitalization, at 2 years and 5 years follow-up were analyzed. Results: A total of 1 920 AMI patiens were included(age was (56.5±11.3) years old),with 1 612(84.0%) males. There were statistically significant differences between the two groups in gender, body mass index, blood lipid, complications, inflammatory markers, etc (all P<0.05). Multivariate logistic regression analysis showed body mass index(OR=1.06, 95%CI 1.01-1.10, P<0.01), triglyceride(OR=1.47, 95%CI 1.14-1.90, P<0.01), serum uric acid level(OR=1.02, 95%CI 1.01-1.04, P<0.01), high density lipoprotein cholesterol level(OR=0.33, 95%CI 0.14-0.78, P=0.01) and history of hypertension(OR=0.72, 95%CI 0.56-0.93, P=0.01) were independent related factors of premature AMI. The incidence of all-cause death and cardiac death were lower during hospitalization, at 2 years and 5 years follow-up in the premature AMI group than in non-premature AMI group(all P<0.05). In the premature AMI group, the incidence of MACCE and stroke was lower, with more bleeding events in 5 years follow-up(all P<0.05). Conclusions: Metabolic abnormalities, including high BMI, high triglyceride level and high serum uric acid, low high-density lipoprotein cholesterol level are the related factor of premature AMI. The incidence of ischemic events in patients with premature AMI is lower, while the incidence of bleeding events is higher than non-premature AMI patients.

ABSTRACT

Objective: To analyze the association between plasma high-density lipoprotein cholesterol (HDL-C) levels and the severity of coronary artery disease, and to evaluate the impact of HDL-C levels on long-term outcomes in patients underwent percutaneous coronary intervention (PCI). Methods: A total of 10 458 consecutive patients underwent PCI from January 2013 to December 2013 at Fuwai hospital were enrolled in this study. Patients were divided into three groups according to HDL-C tertiles: low HDL-C group (HDL-C≤0.89 mmol/L, n=3 525), median HDL-C group (HDL-C>0.89-1.11 mmol/L, n=3 570) and high HDL-C group (HDL-C>1.11 mmol/L, n=3 363). SYNTAX score was used to evaluate the severity of coronary artery disease, linear regression was used to analyze the relationship of HDL-C and SYNTAX score. Kaplan-Meier survival analysis was used to compare the outcomes among the three groups. Multivariate Cox regression was used to define the potential associations of HDL-C and outcomes. Results: The HDL-C level was (1.03±0.28) mmol/L and the SYNTAX score was 11.7±8.1. Patients were older, proportion of female, stable angina pectoris, successful PCI and left ventricular eject fraction value were higher, while incidence of diabetes mellitus was lower, hyperlipidemia, old myocardial infraction, smoking history and left main and three vessels disease were lower in high HDL-C group (all P<0.05). Patients in high HDL-C group also had the lowest SYNTAX score (12.2±8.4 vs. 11.7±8.1 vs. 11.2±7.8, P<0.001). Both univariate and multivariate linear regression analysis showed that HDL-C was negatively associated with SYNTAX score, e.g. Univariate analysis: β=-0.046, P<0.001; Multivariate analysis: β=-0.058, P=0.001. And 10 400 (99.4%) patients completed 2-year follow up. At 2-year follow-up, there were no difference in all-cause death, cardiac death, myocardial infarction, revascularization, stroke, major adverse cardiovascular and cerebral events (MACCE) and stent thrombosis among three groups (P for trend>0.05), while patient in high HDL-C group experienced the highest BARC type 2 bleeding events (P for trend=0.018). Multivariate Cox regression analysis showed that HDL-C level was not an independent risk factor of 2-year adverse ischemia events (P>0.05) and 2-year bleeding events (P>0.05). Conclusion: In patients underwent PCI, plasma HDL-C level is negatively associated with SYNTAX score, but not an independent risk factor of ischemic and bleeding events post PCI.

ABSTRACT

Objective:To explore the effect of childhood traumatic experience and impulsive traits on symptom dimensions in patients with obsessive-compulsive disorder(OCD).Methods:A cross-sectional study was performed to enroll 134 patients with obsessive-compulsive disorder diagnosed by DSM-Ⅳ and 82 healthy controls to match. The obsessive compulsive inventory-revised(OCI-R) questionnaire, and the Barratt impulsiveness scale (BIS-11) and Childhood trauma questionnaire-short form(CTQ-SF) were used to assess the symptom dimensions, impulsive traits, and childhood trauma levels of two groups.The Yale-Brown Obsessive-compulsive Scale (Y-BOCS) was used to assess severity of disease in OCD patients. The scores of each dimension of obsessive-compulsive symptoms were used as dependent variables. The impulse characteristics of different components and childhood trauma scores were independent variables. Multivariate regression analysis was used to explore the influence of impulsive traits and childhood trauma on obsessive-compulsive symptoms.Results:The scores of OCD patients in nonplanning impulsivity (26.80±4.57), attentional impulsivity(18.96±3.51), emotional abuse(6 (5, 9)), physical abuse (5(5, 6)), emotional neglect (11 (9, 14)) were higher than those in healthy controls ((24.39±4.15), (16.18±2.76), 6 (5, 7), 5 (5, 5), (10.00±3.42) respectively) ( P<0.05, P<0.01). Each subscore of OCI-R in patients with OCD was significantly higher than those in healthy controls (all P<0.01). Multiple regression analysis indicated that the ordering scores of obsessive-compulsive patients was affected by attentional impulsivity and physical neglect ( B=0.191, P=0.011; B=0.273, P=0.005). The emotional abuse was the major impact factor of the hoarding symptom ( B=0.204, P=0.002). The score of obsessions was affected by attentional impulsivity and emotional abuse ( B=0.499, P<0.01; B=0.175, P=0.008). The scores of neutralizing were influenced by attentional impulsivity and physical neglect ( B=0.365, P<0.01; B=0.199, P=0.034). Conclusion:Childhood trauma and attentional impulsivity of OCD patients have different effects on different obsessive-compulsive symptoms.

ABSTRACT

Objective@#To analyze factors associated with unplanned revascularization (UR) risk in patients with coronary artery disease (CAD) who underwent percutaneous coronary intervention (PCI).@*Methods@#A total of 10,640 cases with CAD who underwent PCI were analyzed. Multivariate COX regressions and competing risk regressions were applied.@*Results@#The patients who underwent UR following PCI in 30 days, 1, and 2 years accounted for 0.3%, 6.5%, and 8.7%, respectively. After multivariate adjustment, the number of target lesions [hazard ratio ( ) = 2.320; 95% confidence interval ( ): 1.643-3.277; < 0.001], time of procedure ( = 1.006; 95% : 1.001-1.010; = 0.014), body mass index ( = 1.104; 95% : 1.006-1.210; = 0.036), incomplete revascularization (ICR) ( = 2.476; 95% : 1.030-5.952; = 0.043), and age ( 1.037; 95% : 1.000-1.075; = 0.048) were determined as independent risk factors of 30-day UR. Factors, including low-molecular-weight heparin or fondaparinux ( = 0.618; 95% : 0.531-0.719; < 0.001), second-generation durable polymer drug-eluting stent ( 0.713; 95% : 0.624-0.814; < 0.001), left anterior descending artery involvement ( = 0.654; 95% : 0.530-0.807; < 0.001), and age ( = 0.992; 95% : 0.985-0.998; = 0.014), were independently associated with decreased two-year UR risk. While, Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery score ( = 1.024; 95% : 1.014-1.033; < 0.001) and ICR ( = 1.549; 95% : 1.290-1.860; < 0.001) were negatively associated with two-year UR risk.@*Conclusion@#Specific factors were positively or negatively associated with short- and medium-long-term UR following PCI.

ABSTRACT

Eating disorder is a kind of complex multifactorial disease. Although the etiology of the disease is still not fully expounded, it is certain that its etiology is closely related to biological, psychological and sociocultural factors. It is helpful to make early predictions and interventions for patients with eating disorders by learning through the studies of risk factors for eating disorder, which is also meaningful to provide more guidance and evidence for clinical work. Guided by recent studies, this review summarizes recent findings and clarifies the latest identified risk factors for eating disorders in the main areas of biology, psychology, and sociocultural environment.

ABSTRACT

BACKGROUND@#It is currently unclear if fibrinogen is a risk factor for adverse events in patients receiving percutaneous coronary intervention (PCI) or merely serves as a marker of pre-existing comorbidities and other causal factors. We therefore investigated the association between fibrinogen levels and 2-year all-cause mortality, and compared the additional predictive value of adding fibrinogen to a basic model including traditional risk factors in patients receiving contemporary PCI.@*METHODS@#A total of 6293 patients undergoing PCI with measured baseline fibrinogen levels were enrolled from January to December 2013 in Fuwai Hospital. Patients were divided into three groups according to tertiles of baseline fibrinogen levels: low fibrinogen, <2.98 g/L; medium fibrinogen, 2.98 to 3.58 g/L; and high fibrinogen, ≥3.58 g/L. Independent predictors of 2-year clinical outcomes were determined by multivariate Cox proportional hazards regression modeling. The increased discriminative value of fibrinogen for predicting all-cause mortality was assessed using the C-statistic and integrated discrimination improvement (IDI).@*RESULTS@#The 2-year all-cause mortality rate was 1.2%. It was significantly higher in the high fibrinogen compared with the low and medium fibrinogen groups according to Kaplan-Meier analyses (1.7% vs. 0.9% and 1.7% vs. 1.0%, respectively; log-rank, P = 0.022). Fibrinogen was significantly associated with all-cause mortality according to multivariate Cox regression (hazard ratio 1.339, 95% confidence interval: 1.109-1.763, P = 0.005), together with traditional risk factors including age, sex, diabetes mellitus, left ventricular ejection fraction, creatinine clearance, and low-density lipoprotein cholesterol. The area under the curve for all-cause mortality in the basic model including traditional risk factors was 0.776, and this value increased to 0.787 when fibrinogen was added to the model (IDI = 0.003, Z = 0.140, P = 0.889).@*CONCLUSIONS@#Fibrinogen is associated with 2-year all-cause mortality in patients receiving PCI, but provides no additional information over a model including traditional risk factors.

ABSTRACT

Objective@#Patients with acute coronary syndrome due to multivessel disease (MVD) were at the highest risk of adverse cardiovascular events. Neutrophil to lymphocyte ratio (NLR) was proposed as a marker of cardiovascular risk. Present study evaluated the independent predictive value of NLR for acute myocardial infarction (AMI) patients with MVD.@*Methods@#AMI patients with MVD (n=1 433) underwent percutaneous coronary intervention (PCI) between January 2013 and December 2013 were followed up for 2 years. Patients were divided into 2 sub-groups based on an optimal cut off value of NLR to predict 2-year all-cause mortality. The primary endpoint was all-cause death. The secondary endpoint was long-term major adverse cardiovascular and cerebrovascular events (MACCE).@*Results@#By receiver operating characteristics curve analysis, the optimal cut-off value of admission NLR to predict 2-year all-cause mortality was 3.39 (area under the curve 0.765, sensitivity 71%, specificity 73%). The high NLR group(n=396) had higher prevalence of prior myocardial infarction, prior PCI and intra-aortic balloon pump use (IABP)(P<0.01). Compared to the low NLR group (n=1 037), patients in the high NLR group were older, had higher level of neutrophil count and high-sensitivity C-reactive protein (hs-CRP) (P<0.001), but lower level of lymphocyte count, estimated glomerular filtration rate (eGFR) and ejection fraction (P<0.001). During the follow-up period, rate of long-term all-cause death was significantly higher in the high NLR group than in the low NLR group (5.1% (20/396) vs. 0.8% (8/1 037), P<0.001). Cardiac death (4.0% (16/396) vs. 0.7% (7/1 037), P<0.001) and MACCE (21.7% (86/396) vs. 12.6% (131/1 037), P<0.001) were also significantly higher in the high NLR group than in the low NLR group. Multivariate Cox analysis showed that NLR ≥ 3.39 was determined as an independent predictor of 2-year all-cause mortality (HR=3.23, 95%CI 1.38-7.54, P=0.007) and MACCE (HR=1.58, 95%CI 1.19-2.10, P=0.002) in this patient cohort after adjusting for other risk factors. Correlation analysis showed that the NLR was positively correlated with hs-CRP levels (r=0.241, P<0.001).@*Conclusion@#Our study demonstrates that admission NLR ≥ 3.39 is an independent predictor of long term all cause death and MACCE in AMI patients with MVD post PCI.

ABSTRACT

Objective@#To investigate the impact of coronary lesion calcification on the long-term outcome of patients with coronary heart disease after percutaneous coronary intervention.@*Methods@#In this prospective observational study, a total of 10 119 consecutive patients with coronary heart disease undergoing percutaneous coronary intervention from January 1 to December 31, 2 103 in our hospital were enrolled. The patients were divided into non/mild calcification group (8 268 cases) and moderate/severe calcification group (1 851 cases) according to the angiographic results. The primary endpoint was one-year major adverse cardiovascular events (MACE), including all-cause death, myocardial infarction, and target vessel revascularization.@*Results@#The patients were (58.3±10.3) years old, and there were 2 355 females (23.3%). Compared with non/mild calcification group, patients in the moderate/severe calcification group were older ((60.0±10.6) years vs. (57.9±10.2) years, P<0.01), and had higher proportion of female (25.4% (470/1 851) vs. 22.8% (1 885/8 268), P=0.02), debates (33.9% (628/1 851) vs. 29.0% (2 399/8 268), P<0.01), hypertension (68.0% (1 259/1 851) vs. 63.7% (5 264/8 268), P<0.01), coronary artery bypass grafting (4.6% (85/1 851) vs. 3.2% (268/8 268), P<0.01), stroke (12.6% (233/1 851) vs. 10.4% (861/8 268), P=0.01), and renal dysfunction (6.2% (115/1 851) vs. 3.7% (303/8 268), P<0.01). Compared with non/mild calcification group, patients in themoderate/severe calcification group experienced longer procedure time (37 (24, 61) min vs. 27 (17,40) min, P<0.01) and stent length was longer (32 (23,48) mm vs. 27 (18,38) mm, P<0.01), and percent of rotational atherectomy was higher (2.56%(57/2 229) vs. 0.03% (3/11 930), P<0.01). One-year follow-up results showed that MACE (7.5% (139/1 846) vs. 4.9% (402/8 243), P<0.01), all-cause death (1.0% (19/1 846) vs. 0.6% (49/8 243), P=0.04), myocardial infarction (2.2% (41/1 846) vs. 1.4% (114/8 243), P=0.01), and target vessel revascularization (5.0% (92/1 846) vs. 3.2% (266/8 243), P<0.01) were all significantly higher in moderate/severe calcification group than in non/mild group. Multivariate Cox regression analysis showed that moderate/severe calcification was an independent predictor of MACE at one-year after the procedure (HR=1.41, 95%CI 1.16-1.72, P<0.01).@*Conclusion@#Moderate/severe calcification in coronary lesion is an independent predictor of long-term poor prognosis in coronary heart disease patients undergoing percutaneous coronary intervention.

ABSTRACT

Objective@#To evaluate the efficacy and safety of intravenous thrombolysis with recombinant tissue-plasminogen activator (rt-PA) in elderly patients with early-stage mild ischemic stroke (IS).@*Methods@#This was a prospective, open-label, controlled study.Ninety-four elderly patients with mild IS admitted to our hospital from January 2014 to December 2017 were randomized into a thrombolysis arm (TA, n=46) and a control arm (CA, n=48). The short-term endpoints were the National Institutes of Health stroke scale (NIHSS) scores on 3rd, 7th, 14thday after admission and the secondary endpoints were the modified Rankin Scale (mRS) score and the morbidity of recurrence IS within 90 days.Safety was evaluated by the incidence of intracranial hemorrhage (IH) and early neurological deterioration (END) during hospitalization.@*Results@#The baseline NIHSS scores of patients in the TA and CA groups were similar [(4.1±0.7) vs.(4.1±0.7)]. However, there were significant differences in the NIHSS score on 3rd [(3.4±1.2) vs.(4.2±1.4)], 7th[(3.0±1.8) vs.(4.1±1.6)] and 14thday [(2.5±2.0) vs.(3.4±1.6)], respectively, between the TA group and the CA group.Furthermore, the TA group was associated with a significantly higher proportion of patients with good prognosis (mRS, 0-2), compared with the CA group (71.7% vs.35.4%, P<0.01). Receiver operating characteristic curve analysis showed that patients with baseline NIHSS>3 could benefit from thrombolytic therapy.There were 1 case of symptomatic IH and 1 case of progressive stroke in the TA group, and 1 case of IH and 2 cases of progressive stroke in the control group.There were no significant differences in the rate of either END or IH between the two groups (P>0.05). Two patients in the TA group and three patients in the control group had recurrent IS within 90 days and the recurrence rate of IS was also similar within 90 days (P>0.05).@*Conclusions@#Intravenous thrombolytic therapy with rt-PA can improve the prognosis of elderly patients with mild stroke without increased risk of END, IH, or recurrence of IS.

ABSTRACT

Objective@#To preliminarily observe the effects of application of micro-negative pressure in children with small-area deep partial-thickness burn.@*Methods@#From January 2016 to August 2018, 64 children with small-area deep partial-thickness burn who were admitted to the Department of Burn Surgery of the First Affiliated Hospital of Naval Medical University were recruited in this prospective randomized controlled study. According to the random number table, they were divided into negative pressure group [18 boys and 14 girls, aged (3.9±1.6) years with total burn area of (5.5±2.2)% total body surface area (TBSA)] and conventional group [20 boys and 12 girls, aged (3.8±1.7) years with total burn area of (5.8±1.6)% TBSA], with 32 patients in each group. After admission, simple debridement was performed in the patients of 2 groups. After that, the children in negative pressure group were treated with micro-negative pressure with negative pressure material replaced every 3 to 5 days. Children in conventional group were treated with silver sulfadiazine cream with dressing change every other day. On post injury day (PID) 14 and 21, general wound observation was performed, the wound healing rate was calculated, the exudates from the wounds were cultured and the positive detection rate was calculated. The number of patients requiring surgical skin grafting was recorded and the rate of surgical skin grafting was calculated, and the complete wound healing time was recorded in the patients of 2 groups. Scar formation was evaluated by the Vancouver Scar Scale (VSS) in 3, 6, and 12 months after wound healing. Data were processed with chi-square test, t test, Bonferroni correction, and analysis of variance for repeated measurement.@*Results@#(1) On PID 14, all the necrotic tissue in the wounds of patients in negative pressure group was removed, with few exudates, and most of the wounds had been epithelialized; most of necrotic tissue in the wounds of patients in conventional group was removed, with more exudates and smaller wound healing area than those in negative pressure group. On PID 21, most of the wounds of patients in negative pressure group were healed, and the exudates were rare, while the wound healing area of patients in conventional group was significantly smaller than that in negative pressure group with more exudates. (2) On PID 14 and 21, the wound healing rates [(49.8±3.3)% and (95.8±2.4)%] of patients in negative pressure group were significantly higher than those in conventional group [(40.0±3.2)% and (75.3±2.5)%, t=11.899, 33.461, P<0.01]. (3) On PID 14 and 21, the positive detection rates of wound bacteria of patients in negative pressure group were significantly lower than those in conventional group (χ2=6.275, 5.741, P<0.05). (4) The rate of surgical skin grafting of patients in negative pressure group was significantly lower than that in conventional group (χ2=5.333, P<0.05). (5) The complete wound healing time of patients in negative pressure group [(23.9±2.3) d] was significantly shorter than that in conventional group [(27.9±1.8) d, t=-7.806, P<0.01]. (6) In 3, 6, and 12 months after wound healing, the VSS scores [(6.9±1.8), (5.6±1.4), (3.4±1.5) points] of patients in negative pressure group were significantly lower than those in conventional group [(9.0±1.5), (7.4±2.0), (5.7±1.6) points, t=-4.987, -4.127, -5.988, P<0.01].@*Conclusions@#In comparison with routine dressing change, the treatment of application of micro-negative pressure in children with small-area deep partial-thickness burn can significantly improve the wound healing rate and rate of surgical skin grafting, decrease the wound infection rate, shorten the wound healing time, and improve the wound healing quality.

ABSTRACT

Objective@#To observe the safety and impact of short-term anticoagulant therapy on prognosis after selective percutaneous coronary intervention (PCI) in patients with coronary artery disease.@*Methods@#From January 2013 to December 2013, 9 769 consecutive patients underwent selective PCI in Fuwai Hospital were retrospectively included in this study. Patients were divided into two groups, including non-post-PCI anticoagulant therapy group and low-dose and short-time post-PCI anticoagulant therapy group (enoxaparin 0.4 ml/12 h or fondaparinux 2.5 mg/day by subcutaneous injection for 2-3 days after PCI). All patients were evaluated at 30 days, 180 days and 12 months for major adverse coronary and cerebral events (MACCE) including all-cause death, myocardial infarction, revascularization and stroke as well as in-stent thrombosis and bleeding events. Data from 1 755 pairs of patients were analysis after propensity score matching. The clinical outcomes were compared between groups by using Kaplan-Meier survival analysis before and after propensity score matching. Multivariable Cox analysis was used to define the impact and determinants of post-PCI anticoagulation on clinical outcomes.@*Results@#one thousand seven hundred and fifty-five (18.0%) patients didn′t receive post-PCI anticoagulation and 8 014 (82.0%) patients received post-PCI anticoagulation, 5 666 (58.0%) patients received enoxaparin and 2 348 (24.0%) patients received fondaparinux. Patients were younger and incidence of female patients was less, incidence of renal dysfunction and acute coronary syndrome were higher in low-dose and short-time post-PCI anticoagulant therapy group than in non-post-PCI anticoagulation group (all P<0.05). Similarly, patients with post-PCI anticoagulation were associated with more left main coronary artery lesion and branch lesion (P<0.05). Post-PCI anticoagulation patients were associated with less trans-femoral process, more drug-eluting stents implantation and less simple balloon dilatation (all P<0.05). Nine thousand seven hundred and seventeen (99.5%) patients completed 2 years follow up. Post-PCI anticoagulation patients had significantly lower 30-day all-cause death (0.05% (4 cases) vs. 0.46% (8 cases), P<0.001) and stroke (0 vs. 0.11% (2 cases), P=0.003), lower 180-day all-cause death (0.17% (14 cases) vs. 0.57% (10 cases), P=0.002), revascularization (2.07% (166 cases) vs. 3.71% (65 cases), P<0.001) and MACCE (3.49% (280 cases) vs. 5.47% (96 cases), P<0.001), lower 2-year revascularization (7.61% (610 cases) vs. 12.84% (225 cases), P<0.001) and MACCE (10.92 (875 cases) vs. 16.01% (281 cases), P<0.001). Multivariable Cox regression analysis showed that post-PCI anticoagulant therapy was an independent protective factor of 30-day (HR=0.17, 95%CI 0.05-0.62, P=0.007), 180-day all-cause death (HR=0.37, 95%CI 0.16-0.87, P=0.023) and MACCE (HR=0.74, 95%CI 0.58-0.94, P=0.013), 2-year MACCE (HR=0.71, 95%CI 0.62-0.81, P<0.001). After propensity score matching, post-PCI anticoagulation therapy remained as an independent protective factor of 30-day all-cause death (HR=0.11, 95%CI 0.01-0.92, P=0.042) and 2-year MACCE (HR=0.81, 95%CI 0.68-0.96, P=0.015).@*Conclusions@#Low-dose and short-time post-PCI anticoagulant therapy may decrease 30-day all-cause death, 180-day all-cause death and MACCE and 2-year MACCE, and meanwhile this option does not increase bleeding risk in patients underwent selective PCI.
