Objective To investigate the effect of restriction decision wheel and grade ICU patients with critical consciousness disorder. Methods Two hundred and fifty four patients in ICU with critical consciousness disorder from July to December 2012, who were intubated and constrained with their limbs due to the risk of unexpected extubation, were divided into the control group (n=125) and the experiment group (n=129), according to registration sequence. The former were constrained to their limbs after evaluation referring to the constraint nursing form and the latter was constrained by using the constraint decision-making wheel and grade. The two groups were compared in terms of restraint rate, unplanned extubation rate, and incidence of skin abnormality. Results The restraint rate of the observation group was significantly lower than that of the control group (P<0.01). There was no incidence of abnormal skin in the two groups. There was no significance in the rate of unplanned extubation between the two groups (P>0.05). Conclusion Constraints decision making wheel and grade is effective in ensuring patients'safety and improving the quality of nursing safety management by reducing unnecessary constraints or the incidence of delayed constraints.

OBJECTIVE To explore the effect of clofenotane (DDT) on epithelial-mesenchymal transition (EMT) and the relevant molecular mechanism in human colorectal cancer cells. METHODS Human colorectal cancer cells DLD1 were treated with DDT 0.01, 0.1, 1.0, 10.0 and 100.0 nmol·L-1 for 48 h. Then, the morphology of DLD1 cells was observed. mRNA levels of E-cadherin, N-cadherin, vimentin and Snail1 were detected by real-time PCR. Protein expression of STAT3 signaling pathway of proteins STAT3 and p-STAT3 was detected by Western blotting. STAT3 inhibitor WP1006 (5μmol · L-1) was added to determine its impact on DDT-induced alternation of STAT3/Snail1 signaling and EMT-related molecules. Protein expression of STAT3 and p-STAT3 was detected by Western blotting and mRNA levels of E-cadherin, N-cadherin, Vimentin and Snail1 were detected by real-time PCR. RESULTS DLD1 cell morphology was changed after exposure to DDT 0.01-100.0 nmol · L- 1. Meanwhile, real-time PCR showed that the mRNA level of E-cadherin was significantly decreased compared with normal cell control (P<0.01), which was 42.4±2.8%of that in the normal control group. The mRNA levels of N-cadherin, Vimentin and Snail1 were significantly increased (P<0.01), which were 1.91±0.1, 1.5±0.2 and 1.5±0.1 times that of the normal control group. DDT 0.1, 1.0 and 10.0 nmol · L-1 exposure induced up-regulation of STAT3 and p-STAT3 protein levels (P<0.01), which were 2.1 and 1.8 times that of the normal control group. The addition of STAT3 inhibitor WP1066 (5 μmol · L-1) prevented STAT3 from phosphorylation as well as the up-regulation of Snail1(P<0.01), which was (56.3 ± 0.9)% that of the DDT 1.0 nmol · L-1 treat?ment group. Compared with DDT treatment alone, the mRNA levels of EMT-related molecules were remarkably reversed by WP1066 (5 μmol · L- 1) co-treatment, increasing E-cadherin but decreasing N-cadherin and vimentin in DLD1 cells(P<0.01), which were 50.2±2.9%and 61.6±6.1%of those in the DDT 1.0 nmol · L- 1 treatment group, respectively. CONCLUSION DDT alters the expressions of EMT-related molecules including E-cadherin, N-cadherin and vimentin via STAT3/Snail1 signaling, thus promoting the EMT process in human colorectal cancer cells. This progress may be closely related to DDT-induced colorectal cancer development.

Objective To investigate the outcome of free posterolateral leg perforator flap in the reconstruction of soft tissue defects of oral and maxillofacial area.Methods From February,2014 to August,2016,16 patients were performed defect reconstruction following oral cancer ablation with free posterolateral leg perforator flap including 3 cases of sequamous cell carcinoma of the tongue,6 cases of carcinoma of the buccal mucosa,7 cases of sequamouse cell carcinoma of the floor of mouth.The flap ranged from 5.0 cm×3.0 cm to 13.0 cm ×9.0 cm in size,and were adjected to the soft tissue defects of oral and maxillofacial area.The outcome of reconstruction was evaluated by considering the facial appearance,the swallowing and the speach function,the ranges of mouth opening and patient prognosis.Results All 15 transplanted flaps survived well and only 1 survived after disposing in time,because of vascular crisis.The donor sites were closed directly without donor-site morbidity.All patients were satisfactory with their facial appearance,the ranges of mouth opening and swallowing and speech function.Conclusion The free posterolateral leg perforator was an ideal free tissue for repairing functionally oral and maxillofacial defects,sinceit including some beneficial characteristic such as constant blood vessel,flexible and divese design,abundant and position-latent donor site tissues,small operation loss,flexible preparation and loss of major vascular nerves.

Objective ST-T complex change, which represents the ventricle repolarization phase, is the main clinical indicator in detecting myocardial ischemia (MI) based on electrocardiogram (ECG) signals.However, its feature point location is not accurate due to interferences. In this paper, a new approach about myocardial ischemia analysis was proposed based on QRS complex. Methods QRS complex, representing the ventricle depolarization process, was used to analyze myocardial ischemia, and some parameters were extracted synthetically in time domain. Then they were used for statistical analysis of myocardial ischemia states and non-myocardial ischemia states. Results Five parameters had significant differences after verification of Non-MI signals in MIT-BIH database and MI signals in long-term ST database (LTST) and they were: QRS upward and downward slopes, transient heart rate, R angle and Q angle in a triangle QRS. Conclusion Five parameters extracted from QRS complex had significant differences. The proposed method provides an important basis for myocardial ischemia detection.
