ABSTRACT

Objective:To optimize the clinical nursing pathway, service program and evaluation parameters of percutaneous coronary intervention(PCI), for references for the cost accounting and compensation mechanism of nursing program in public hospitals.Methods:After literature analysis and group discussion, the initial templates were constructed for the PCI clinical nursing pathway, nursing service projects, and their evaluation parameters. 15 experts were consulted by two rounds of Delphi method to optimize PCI nursing path, nursing service items and their evaluation parameters (basic labor consumption, basic time consumption, technical difficulty and risk degree).Results:Two rounds of Delphi method finally determined the PCI clinical nursing path and 27 nursing service items, and adjusted the evaluation parameters of 10 nursing service items. The new projects for PCI clinical nursing services included adjustment and review of dual antiplatelet therapy plans, postoperative rehabilitation nursing, and key project verification. The three nursing service projects with the highest level of technical difficulty and risk were intravenous blood transfusion, gastric catheterization, and gastrointestinal decompression. The two items with the highest importance assigned were high pump assisted arterial/venous infusion (blood) and invasive continuous arterial blood pressure monitoring.Conclusions:The PCI clinical nursing pathway and nursing service project constructed in this study could closely integrate with clinical practice, highlight the integrated nursing service model, and reflect the labor value of nurses.

ABSTRACT

Objective@#To quantitatively assess biochemical alterations in the cartilage of the subtalar and midtarsal joints in chronic lateral ankle instability (CLAI) patients with isolated anterior talofibular ligament (ATFL) injuries and combined calcaneofibular ligament (CFL) injuries using MRI T2 mapping. @*Materials and Methods@#This study was performed according to regulations of the Committee for Human Research at our institution, and written informed consent was obtained from all participants. Forty CLAI patients (26 with isolated ATFL injuries and 14 with combined ATFL and CFL injuries) and 25 healthy subjects were recruited for this study. All participants underwent MRI scans with T2 mapping. Patients were assessed with the American Orthopedic Foot and Ankle Society (AOFAS) rating system. The subtalar and midtarsal joints were segmented into 14 cartilage subregions. The T2 value of each subregion was measured from T2 mapping images. Data were analyzed with ANOVA, the Student’s t test, and Pearson’s correlation coefficient. @*Results@#T2 values of most subregions of the subtalar joint and the calcaneal facet of the calcaneocuboid joint in CLAI patients with combined CFL injuries were higher than those in healthy controls (all p 0.05). Moreover, T2 values of the medial talar subregions of the posterior subtalar joint in patients with combined CFL injuries showed negative correlations with the AOFAS scores (r = -0.687, p = 0.007; r = -0.609, p = 0.021, respectively). @*Conclusion@#CLAI with combined CFL injuries can lead to cartilage degeneration in subtalar and calcaneocuboid joints, while an isolated ATFL injury might not have a significant impact on the cartilage in these joints.

ABSTRACT

Objective To investigate the effect of BOPPPSmodel in the clinical teaching of ward inspection in the standardized training of residents in the department of obstetrics and gynecology. Methods Residents who participated in the standardized training in the department of obstetrics and gynecology in our hospital (January to December 2016) were randomly divided into two groups: teaching experimental group(n=30) and control group(n=35). BOPPPSteaching and traditional teaching methods were applied respectively. The comprehensive assessment scores of the theory test, skill operation test and questionnaire survey were evaluated in both groups. Results The comprehensive assessment scores of the fundamental knowledge test, clinical skill operation test and questionnaire survey in the teaching group were significantly higher than those in the control group(P<0. 05). Most students in BOPPPSteaching group held the opinions that BOPPPSteaching could help to improve learning initiative, cultivate communication skills of doctors to patients, stimulate clinical thinking, and improve learning efficiency. At the same time, students also mentioned that the BOPPPSmodel had a greater pressure on them, which consumed a great number of time and energy. There were significant differences in the scores between the two groups(P<0. 05). Conclusion Application of BOPPPSmodel teaching of ward inspection in the standardized training of residents in the department of obstetrics and gynecology can contribute to the improvement of teaching quality and comprehensive ability of the trainees.

ABSTRACT

Malignant pleural mesothelioma (MPM) is a tumor of mesodermal origin that arises from the serosa of the pleura, peritoneum, pericardium or tunica vaginalis. MPM is well known to have a poor prognosis with a median survival time of 12 months. Accurate diagnosis, staging and restaging of MPM are crucial with [18F] flurodeoxy-D-glucose positron emission tomography (FDG PET/CT) playing an increasingly important role. Here we report a case of MPM with unusual contiguous soft tissue spread of the tumor along the dermal and fascial planes characterized by PET/CT. Given that the loco-regional tumor in the thorax was under control on PET/CT, the death of the patient was most likely associated with physiologic or metabolic causes associated with an extra-thoracic tumor.

ABSTRACT

Objective To verify whether early growth response-3(EGR3) gene is targeted by microRNA-181b using molecular biology methods so as to provide guidance for the subsequent study on microRNA-181b`s role in the molecular mechanisms of schizophrenia.Methods Bioinformatic methods predicted that EGR3 gene is targeted by microRNA-181b.PCR methods amplified the fragment in EGR3 gene 3`UTR including the putative microRNA-181b binding site.Then the sequence was cloned into the pmirGLO luciferase vector.The DNA sequences of the amplified fragments were identified by restriction enzyme digestion and sequencing, and were consistent with the reference sequence from UCSC.This constructed vector was marked as pmirGLO-EGR3 vector.Finally, the pmirGLO vector, the pmirGLO-EGR3 vector, microRNA-181b mimics and negative control (NC) were divided into 5 groups and transfected into HEK393T cells;the luciferase activity was tested by dual luciferase reporter gene assay.Results The results of restriction enzyme digestion and sequencing demonstrated that the PCR fragmentwas successfully cloned into pmirGLO vector.The transfection results showed that the recombinant plasmid was successful transfected into HEK293T under the fluorescence microscope, with transfection efficiency being about 90%.The results of dual luciferase activity assay demonstrated that microRNA-181b significantly decreased the reporter gene`s activity compared with the NC.Conclusion At the cellular level, the schizophrenia susceptibility gene EGR3 was verified to be targeted by micorRNA-181b, which provides a new clue for the subsequent study on microRNA-181b`s role in the molecular mechanisms of schizophrenia.

ABSTRACT

To establish an animal model of acute-on-chronic liver failure (ACLF) that would replicate the pathological process of ACLF in humans, rats were administered porcine serum (PS) for 11 weeks. Liver fibrosis was determined by pathological and biochemical assessments. The animals then were injected with d-galactosamine (d-gal) and lipopolysaccharide (LPS). The survival times of animals with cirrhosis and ACLF were determined over 48 h. Other animals were killed at 0, 4, 8 and 12 h after administration of d-gal/LPS. Liver injury was assessed by histopathological analysis and biochemical indices, and apoptosis was detected by Western blot and TUNEL analysis. After PS administration for 11 weeks the serum levels of hyaluronic acid and N-procollagen type III peptide increased significantly, and serious fibrosis and cirrhosis was observed at weeks 10 and 11. Cirrhotic rats were injected with d-gal/LPS to induced ACLF; the rate of mortality over 48 h was 80%. ALT and AST levels increased markedly at 4 h, but decreased significantly at 8 and 12 h post-treatment. The total bilirubin, direct bilirubin, and total bile acids levels increased markedly at 8 and 12 h. Clotting times, TNF-and IL-6 levels increased significantly, except for 12 h post-treatment. Apoptosis, inflammation and necrosis were elevated as determined by hematoxylin-eosin staining and TUNEL assays. BCL-2 levels decreased significantly, While BAX levels increased significantly. Cytochromeexpression peaked at 8 h post-d-gal/LPS treatment. In conclusion, an ACLF model induced by PS and d-gal/LPS was established and the underlying mechanisms of ACLF development were explored.

ABSTRACT

Tetralogy of Fallot (TOF) is one of the most common forms of cyanotic congenital heart disease usually managed by serial surgical repairs. The repaired prosthetic valve or conduit is susceptible to life-threatening infection. FDG-PET is an effective alternative to evaluate the source of infection when other examinations are inconclusive. We report an unusual case of an infected pulmonary artery conduit after TOF repair although the echocardiogram was negative for vegetation, which was later confirmed by surgery and pathology. The case highlights the role of FDG-PETas a problem-solving tool for potential endocarditis and cardiac device infection cases after complex cardiac surgery.

ABSTRACT

OBJECTIVE@#To investigate the expressions of transforming growth factor beta1 (TGF-beta1) and bone morphogenetic protein-2 (BMP-2) in human mandible fracture callus and their quantity changes in the process of healing.@*METHOD@#Thirty callus samples from the fractured mandible bone stumps were collected during operation, and two callus samples were collected from the angle-square jaw patients as controls. The expressions of TGF-beta1 and BMP-2 were test by the immunohistochemistry technic-SABC-staining in different periods of human fractured mandibular callus and in osseous tissue of normal angle of mandible.@*RESULT@#The TGF-beta1 and BMP-2 were expressed in callus of different periods but not in normal bone tissue. The expression of TGF-beta1 increased slowly during the first three weeks after fracture and reached its maximum in the third week, and then weakened gradually. The expression of BMP-2 increased gradually during the first two weeks after fracture and reached its maximum in the second week, then the expression weakened gradually.@*CONCLUSION@#(1) BMP-2 may be one of the factors promoting the repair of fracture. (2) TGF-beta1 could be another signal pathway in repairment of fracture. (3) There could exist some synergistic effects between TGF-beta1 and BMP-2 in the process of fracture healing.

ABSTRACT

Objective To investigate the risk factors of uroschesis in patients with cervical cancer after extensive hysterectomy.Methods The clinical data of 92 patients with cervical cancer who had undergone extensive hysterectomy plus pelvic lymph node dissection from August 2008 to June 2011 were analyzed retrospectively.The incidence rate and related risk factors of uroschesis after operation were analyzed.Results Thirty-one of 92 cases had postoperative uroschesis.The incidence rate of uroschesis was 33.70%.Univariate analysis showed that age,intraoperative blood loss,time of indwelling urinary catheter and urinary tract infection had significant correlation with postoperative uroschesis (P <0.05).While operative time,clinical stage,pathological type,preoperative adjuvant therapy,postoperative wound infection or fat liquefaction had no obvious correlation with postoperative uroschesis (P> 0.05).Multivariate Logistic regression analysis showed that age,time of indwelling urinary catheter and urinary tract infection were risk factors of postoperative uroschesis.Conclusions Age,time of indwelling urinary catheter and urinary tract infection are independent factors of postoperative uroschesis.The key method to reduce the incidence rate of postoperative uroschesis is to shorten the continuous catheterization time with comprehensive measure,to prevent and control urinary tract infection in early time.

ABSTRACT

The purpose of the present study is to use beta-cyclodextrin polymers (beta-CDP) with different cross-linked degree (CLD) to form inclusion complexes with ibuprofen and examine the effects of structural and compositional factors of beta-CDP on its drug loading and release behaviors. A series of beta-CDP with different CLD were synthesized and characterized by Fourier Transform Infrared Spectroscopy (FT-IR) and 13C NMR spectrum. The beta-CDP was systemically characterized for the relation between the CLD of beta-CDP and the drug loading and release as well. The results of FT-IR and 13C NMR showed that similar peak-shaped vibration of beta-CDP and beta-CD implies that the polymer keeps the original characteristic structure of beta-CD. The CLD of the beta-CDP played a critical role in the drug loading and release, increasing the CLD resulted in reduction of drug loading, but increase in drug release.

ABSTRACT

Background and purpose:In order to look for the new biomarker with higher specificity and sensitivity, we investigated the relationship between expression of MGB-2 and chemotherapy response, and tried to find out whether MGB-2 may sever as a prognostic factor for the patients with ovarian carcinoma. Methods:The expression of MGB-2 was detected by flow-cytometry technology in ovarian carcinoma tissue. We analyzed the correlations among MGB-2 expression and clinical pathological factors, therapeutic effect and prognosis of the patients with ovarian carcinoma.Results:Positive detection of MGB-2 was 78%.(66/885). For the patients whose serum CA125 level did not drop to normal level after two courses of chemotherapy, the MGB-2 positive rate was significantly higher than in those whose serum CA125 level decreased markedly ( 85% vs. 62%, P=0.018). The positive rate was also higher in patients with recurrent disease than in those without recurrence (83% vs. 67%, P=0.097). In univariate survival analysis, the expression of MGB-2 was significantly associated with median survival time (P=0.021).Conclusions:MGB-2 expression is correlated with chemotherapy response and poor prognostic for the patients with ovarian carcinoma.

ABSTRACT

Neurotrophic factors are proteins that play an important role in the development and maintenance of neural networks. They released in the brain's response to injury and in neurodegenerative disorders and took part in the protective process. The fact that they can be used to prevent damage to neurons associated with brain lesions in animal models of neurodegenerative disorders supports the above mentioned hypothesis as well. However, they are proteins that do not easily cross the blood brain barrier. The induction of neurotrophic factors by systemically administered some medicines would be an elegant way to overcome problems of application.

ABSTRACT

In both clinical and animal experiments,it has been confirmed that the inflammation in brain is involved in the development of brain damage after the ischemia.However,the pro-inflammatory mechanism is extremely complicated.Recently,a growing number of reports indicates that many factors play their roles in the inflammation,such as leukocyte,interleukin-1?(IL-1?),tumor necrosis factor(TNF)and mast cells.They are released/presented in the region of cerebral ischemia and include both ischemic and secondary brain injury.
