Objective To explore the effects of self-differentiation,social support,social adaptation on suicidal ideation.Methods A simplified cluster sampling method,involving the random selection of 3097 college students in 23 departments,was used to estimate the scores of Chinese version of Self Differentiation Inventory for university student(SDI),Social Support Rating Scale(SSRC),College Student Adaptability Scale (CSAS) and Adult Suicidal Ideation Questionnaire(ASIQ).The independent-samples t-test,Pearson correlation coefficients and stepwise regression analyses were used as statistical analysis techniques.Results The correlation coefficients were negatively significant between suicidal ideation and self-differentiation,social support and social adaptation (r=-0.24,-0.17,-0.29,P＜0.001).Social adaptation showed the strongest predictability for suicidal ideation (β=-0.19,P＜0.001),followed by self-differentiation (β3=-0.13,P＜0.001),social support (β3=-0.08,P＜0.001).Independent samples t-test showed that college students with suicidal ideation showed a significant reduction in interpersonal adaptation,social support,self-differentiation compared to those without suicidal ideation.Conclusion Self-differentiation level,social support and social adaptability may be effective predictors for suicidal ideation among college students.Future intervention programs may focus on enhancing the interpersonal skills of college students to reduce prevalence of suicidal behavior.

With the continuous development of musculoskeletal ultrasound,ultrasound diagnosis of inflammatory arthri tis,especially early diagnosis had an increasing important role.Psoriatic arthritis (PsA) was a kind of inflammatory arthritis,which was closely related with psoriasis.It could involve the whole body's large and small joints,especially peripheral joints (often asymmetric),sacroiliac joint and spine.The course of PsA was protracted and easy to recur.Clinical and ima ging manifestations of PsA are similar to rheumatoid arthritis (RA),and need to identify diagnosis.The diagnosis and antidiastole in musculoskeletal ultrasound of PsA were reviewed in this article.

Objective Atherosclerosis is widely accepted as a chronic inflammatory disease. Serum biomarkers for vulnerable plaques not only serve as diagnostic tools for the identification of patients with acute coro-nary syndrome, but also assist the identification of high-risk patients. However, the existing data are limited and conflicting. In the present study, we determined whether the plasma levels of interleukin-1β (IL-1β) are correlated with adverse cardiac outcomes in patients with ST-evaluate acute myocardial infarction (STEAMI) undergoing pri-mary percutaneous coronary intervention (PCI). Effect of the plasma intedeukin-1β level on prognosis of patients with ST-segment elevation acute myocardial infarction. Method This prospective single-center study included 96 patients with SIEAMI with onset < 12 h who underwent primary PCI, 271 patients with stable angina pectoris (SAP) and 148 control subjects without coronary artery disease who were consecutively admitted to hospital be-tween Mar, 2006 and Mar, 2008. Plasma IL-1β levels were measured by enzyme-linked immunosorbent assay in all subjects. The patients with STEAMI were then followed prospectively for the occurrence of major adverse car-diac events (MACE) (including cardiovascular death, non-fatal myocardial infarction, heart failure, and cardio-genie shock) during hospitalization. We determined the association between IL-1β levels with the risk of MACE using multivariate logistic regression. Results Compared with the SAP patients and control subjects, patients with STEAMI had higher levels of IL-1β (P < 0.05). During hospitalization, 32 patients (33.3%) experienced MACE [23 males, 9 females; age: (75.44±13.45) years]. In the STEAMI patients, IL-1β was elevated in patients with MACE compared with patients without MACE (median [range]: 26.52 [12.010 to 155.244] pg/mL vs 2.157 [0.433 to 83.021] pg/mL; P < 0.01) by non-parameter analysis. Significant and positive correlations be-tween IL-1β and cardiac troponin-I (cTnI) (r = 0.353, P =0.004) were observed by Spearman's correlations analysis. Multivariate logistic regression analysis revealed that IL-1β levels ≥20 pg/mL were significantly and in-dependently associated with MACE during hospitalization (odds ratio: 32.05; 95% confidence interval: 4.28 to 240.151; P =0.001). Conclusions The present study revealed that patients with STEAMI had elevated IL-1β levels on admission. The plasma IL- 1β level is an independent inflammatory predictor for in-hospital MACE in pa-tients with STEAMI undergoing percutaneous coronary intervention.

Objective To explore the risk factors associated with cardiac valve calcification(CVC)in main-tenance hemodialysis patients and its effect on long-term prognosis.Methods A total of 157 patients with ma-intenance hemodialysis who underwent echocardiography in the hospital from January 1,2016 to January 1,2018 were retrospectively analyzed.The subjects were divided into 101 cases in non-CVC group and 56 cases in CVC group according to the results of cardiac ultrasound examination,and the clinical data were compared be-tween the two groups.Multivariate Logistic regression model was used to analyze the risk factors of CVC in maintenance hemodialysis patients.Kaplan-Meier survival curve and Cox regression model were used to ana-lyze the relationship between CVC and all-cause death in maintenance hemodialysis patients.Results The dia-betes history ratio,triglyceride,serum corrected calcium,serum phosphorus and C-reactive protein(CRP)lev-els in CVC group were higher than those in non-CVC group,and the serum albumin level was lower than that in non-CVC group,with statistical significance(P＜0.05).CRP,diabetes history,serum albumin＜35 g/L,serum corrected calcium＞2.35 mmol/L and high serum phosphorus were independent risk factors for CVC in maintenance hemodialysis patients(P＜0.05).CVC,age,serum albumin＜35 g/L and high serum phos-phorus were independent risk factors for all-cause death in maintenance hemodialysis patients(P＜0.05).Conclusion CRP,diabetes history,serum albumin＜35 g/L,serum corrected calcium and high serum phos-phorus are closely related to the occurrence of CVC in maintenance hemodialysis patients,and CVC,age,ser-um albumin＜35 g/L and high serum phosphorus are correlated with long-term all-cause death in mainte-nance hemodialysis patients.

OBJECTIVETo compare two different routes of totally implantable venous access ports (TIVPs) from the upper arm vein and the subclavian vein in terms of complications for patients with gastrointestinal malignancy.

METHODSPatients who underwent implantations of TIVPs from September 2013 to January 2015 were retrospectively evaluated. The outcome measurements were rates and types of postprocedural early-stage and long-term complications.

RESULTSA total of 208 patients(upper arm vein group, 86; subclavian vein group, 122) were included in this study. All TIVPs were implanted successfully. The rate of catheter displacement was higher in upper arm vein group(14.0% vs 5.7%, P=0.04), while other postprocedural early-stage complications had no significant difference between the two groups. The occurrence of transfusion obstacle and rates of overall postprocedural long-term complications were significantly lower in upper arm vein group than that in subclavian vein group(1.2% vs. 9.8%, P=0.02; 7.0% vs. 27.0%, P=0.01, respectively).

CONCLUSIONCompared with subclavian vein group, upper arm vein group has lower postprocedural long-term complication rates and is recommended as a safe and comfortable choice for port implantation.

Objective To investigate the effects of xenogenic bone with chitosan/norvancomycin sustained-release biomaterials in treating infectious bone defects in rabbits.Methods Xenogenic bone with chitosan/norvancomycin sustained-release biomaterials was made by electrospinning technique.Rabbit infectious bone defect models were made by Methicillin-resistant Staphylococcus aureus.A successful model was evaluated with the standard of more than three points in Norden score assessment.All models were divided into two groups by random number table method,with eight models in each.The control group was treated with surgical debridement,and the experimental group was implanted with bone particles of xenogenic bone with chitosan/norvancomycin sustained-release system after debridement.Postoperatively,general conditions,X-ray,histological results of HE staining,and bacteriological examination results of the rabbits were observed.Results X-ray showed significant bone defects,sequestration,periosteal reaction,and soft tissue swelling after one month of modeling,with Norden score of (3.84 ± 0.52) points.The general conditions were good and the sinus tracts were healed in experimental group after two months of treatment.The control group demonstrated generally poor conditions with swollen sinus and purulent discharge.Two rabbits were died of sepsis.The pathological scores of tibial were (0.41 ± 0.08) points in experimental group,and (3.27 ± 0.26) points in control group by gross observation.The pathological score of experimental group was significantly lower than control group(P ＜ 0.05).The bone defects were basically repaired in experimental group.The longest diameter of bone defect in experimental group was (0.11 ± 0.02)cm,significantly smaller than (0.48 ± 0.06) cm in control group (P ＜ 0.05).There were no obvious signs of osteomyelitis and the bone defects were well repaired in experimental group.Periosteal reaction,soft tissue swelling,a substantial number of bone destruction,and sequestration were observed in control group.The Norden score was (1.32 ± 0.23) points in experimental group,lower than (5.21 ± 0.48) points in control group(P ＜ 0.05).HE staining showed a large amount of trabecular bone formation,bone cell formation,and fibrous hyperplasia in experimental group,with no obvious signs of infection.On the other hand,infiltration of inflammatory cells,necrotic tissue,and sequestration were observed in control group.The histological score was(0.61 ± 0.10) points in experimental group,lower than (4.21 ± 0.41) points in control group (P ＜0.05).The negative rate of bacterial culture in experimental group was 33％,lower than 100％ in control group (P ＜ 0.05).Conclusion Xenogenic bone with ehitosan/norvancomycin sustained-release biomaterials has excellent effect in infection clearance and bone defect reparation in treatment of infectious bone defects in rabbits.

Objective:To explore the risk factors of intensive care unit acquired weakness (ICUAW) in patients with sepsis, and to evaluate the predictive value of each risk factor for ICUAW.Methods:A case control study was conducted, 60 septic patients admitted to the intensive care unit (ICU) of Henan Provincial People's Hospital from October 20, 2020 to February 20, 2021 were enrolled. The patients were divided into two groups: sepsis ICUAW group and sepsis non-ICUAW group. The data of gender, age, body mass index (BMI), acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, complications, mechanical ventilation, duration of ICUAW, length of stay in ICU, fasting blood glucose, blood lactic acid (Lac), procalcitonin (PCT), C-reactive protein (CRP), sequential organ failure assessment (SOFA) score, outcome, antimicrobial agent, glucocorticoid, sedatives and analgesics drugs and vasoactive drugs were collected. Risk factors were screened by univariate Logistic regression analysis, and odds ratio ( OR) was adjusted by multivariate binary logistic regression, P < 0.05 was considered as independent risk factors. Finally, the receiver operating characteristic curve (ROC curve) was drawn to analyze the predictive value of independent risk factors. Results:The APACHEⅡ score of the sepsis ICUAW group was significantly higher than that of the sepsis non-ICUAW group (23.05±8.17 vs. 15.33±4.89, P < 0.05), the total length of stay in the ICU was significantly longer than that of the sepsis non-ICUAW group (days: 15.1±9.2 vs. 8.5±3.4, P < 0.05), the improvement rate of patients was significantly lower than that of the sepsis non-ICUAW group [45.0% (9/20) vs. 95.0% (38/40), P < 0.05]. After univariate Logistic regression and multicollinearity test analysis, 7 factors including APACHEⅡ score, average SOFA score, blood lactic acid, proportion of mechanical ventilation, sedatives and analgesics drugs, type of antibiotics and type of vasoactive drugs were included in the binary Logistic regression model [ OR: 1.21, 2.05, 2.26, 0.21, 1.54, 2.07, 1.38, 95% confidence interval (95% CI): 1.09-1.35, 1.42-2.94, 1.12-4.57, 0.05-0.66, 1.03-2.29, 1.27-3.37, 0.96-2.00, all P < 0.05]. Hosmer-Lemchaw test P = 0.901, and the correct percentage of prediction was 85%, indicating good model fit. Multivariate binary Logistic regression analysis showed that APACHEⅡ score and average SOFA score were independent risk factors for the occurrence of ICUAW in septic patients (APACHEⅡscore: OR = 1.17, 95% CI was 1.004-1.376, P = 0.044; average SOFA score: OR = 1.86, 95% CI was 1.157-2.981, P = 0.01). ROC curve analysis showed that the mean value of APACHEⅡ score, average SOFA score and their combined detection had a certain predictive value for the occurrence of ICUAW in sepsis patients, areas under ROC curve (AUC) were 0.787, 0.881, 0.905, 95% CI was 0.646-0.928, 0.791-0.972, 0.828-0.982, all P < 0.05. When the cut-off value was 19.500, 6.225, 0.375, the sensitivity was 75%, 90%, 90%, and the specificity were 80%, 80%, 85%, respectively. Conclusion:APACHEⅡ score and average SOFA score can be used as independent risk factors for the occurrence of ICUAW in sepsis, and their combined predictive value is better than that of individual index.
