Objective To study the effect of transient intensive insulin treatment on the serum free fatty acid (FFA) in newly diagnosed type 2 diabetic patients.Methods Sixty-four newly diagnosed type 2 diabetic patients were treated with transient intensive insulin.The fasting plasma glucose (FPG),2 hours post-prandial glucose (2hPG),lipid,fastin insulin (FINS),and serum FFA was examined hefore and after treatment.Results The levels of FPG,2hPG,total cholesterol (TC),triglycerides (TG),low density lipoproteins cholesterol (LDL-C),FFA and HOMA-IR after treatment were (9.68 ± 2.02) mmol/L,(12.77 ± 1.35) mmol/L,(4.26 ± 1.07) mmol/L,(1.52 ± 0.58) mmol/L,(2.50 ±0.75) mmol/L,(435.84 ± 190.94) μmol/L,0.51 ± 0.62,and they decreased obviously compared with those before treatment [(14.66 ± 3.50) mmol/L,(17.43 ±4.89) mmol/L,(5.03 ±0.94) mmol/L,(2.05 ± 1.42) mmol/L,(2.91 ±0.78) mmol/L,(586.68 ±229.45)μmol/L,0.65 ± 0.89](P＜0.05).The level of HOMA-β increased obviously (2.70 ± 0.83 vs.1.74 ± 1.04)(P＜0.05).The increase of HOMA-β and the decrease of HOMA-IR was positively correlated with the decrease of FFA.Conclusion The transient intensive insulin treatment can evidently decrease the level of FFA that can improve beta-cell function and relieve insulin resistance in newly diagnosed type 2 diabetic patients.

Objective To investigate the current status of application of the Confusion assessment method for the Intensive Care Unit (Cam-ICU),and to explore its influencing factors.Methods A total of 300 patients admitted to were enrolled.The researchers and nurses used Cam-ICU to assess patients' delirium,respectively,and the differences in deliriun assessment were analyzed.Results For delirium assessment,the Kappa value was 0.546 between the researchers and nurses.The consensus rate was 17.6％ for hypoactive delirium,and 77.8％ for hyperactive delirium in 44 delirium patients.Logistic regression analysis showed that APACHE Ⅱ score,RASS score and delirium type were influencing factors of accurate assessment of delirium.Conclusion The consistence of assessment of delirium by ICU nurses is generally good,but the accuracy of assessment of hypoactive delirium is the worst.

Objective To explore the nursing effect of modified prone position and traditional prone position in the skin protection of patients with prone position in ICU. Methods A total of 60 ICU patients with prone position treatment were selected in June 2014 to May 2015. According to the digital method the patients were randomly divided into the control group and the experimental group with 30 cases in each.The control group adopted traditional way of prone position with the head and chest pad pushed up. used by patients not pad up way of improvement of prone position. The incidence of skin pressure injury and the incidence of stress in the two groups were compared. Results The incidence of skin pressure injury was 20.0％(6/30) in the experimental group and 66.7％(20/30) in the control group, and the difference was statistically significant (χ2=13.30, P < 0.05). Conclusions Modified prone position has obvious advantages in reducing the incidence of skin pressure ulcer and is suitable for patients with clinical prone position.

Objective:To analyze the correlation between capillary filling time (CRT) and lactate clearance rate in patients with septic shock, so as to provide reference for the clinical application of CRT in patients with septic shock.Methods:A prospective study was conducted on 70 patients with septic shock. CRT, mean arterial pressure (map) and sequential organ failure (SOFA) score, Acute Physiology and Chronic Health Evaluation Scoring System (APACHE Ⅱ) score, mechanical ventilation and lactate clearance rate were collected at 3 sites (forehead, knee and nail bed) respectively at 2 time points after admission and 6 hours after admission. The correlation between CRT changes and lactate clearance rate was compared.Results:When lactate clearance rate of more than 10% in 6 hours, the Pearson coefficients of the three sites were 0.823 for nail bed ( P<0.05), 0.232 for forehead and 0.254 for knee ( P>0.05). When lactate clearance rate of less than 10% in 6 hours, the Pearson coefficients of the three sites were 0.299 for nail bed, 0.247 for forehead and 0.254 for knee ( P>0.05). Conclusion:When lactate clearance rate of more than 10% in 6 hours, there is a good correlation between the CRT of nail bed and the lactate clearance rate of patients. The CRT of nail bed can be a practical tool for clinical evaluation of microcirculation.

Objective:To analyze the late gadolinium enhancement (LGE) manifestations, cardiac function, and myocardial strain by feature tracking (FT) in Takayasu arteritis (TA) with pulmonary artery involvement (PTA) using cardiac MR (CMR), and then to investigate manifestations of the impaired myocardial structure and function.Methods:A retrospective study was performed on 32 patients with PTA and 21 healthy subjects without cardiopulmonary diseases from January 2017 to December 2020. All of them underwent CMR examinations. According to the presence of pulmonary arterial hypertension (PAH),PTA patients were divided into two groups including PAH group (11 cases) and non-PAH group (21 cases). LGE manifestations were observed and Fisher exact test was used for statistical analysis between the two groups. Cardiac function parameters and FT values including global peak strain of the left and right ventricle were calculated separately in PAH, non-PAH group of patients and healthy controls, using One-way ANOVA or non-parametric Kruskal-Wallis test for statistical analysis including a pairwise comparison between groups. The correlations between FT values of the PAH group and parameters measured by right heart catheterization test (RHC) and transthoracic echocardiography were analyzed using Pearson or Spearman correlation analysis.Results:There were 23 PTA patients (71.9%) with LGE. LGE in the interventricular insertion points (IPs)(11/11), and in the mid-wall (11/11) or epicardial (10/11) myocardium was more common ( P values were 0.006,<0.001 and 0.011, respectively) in PAH group, compared with LGE in the IPs (11/21), and in the mid-wall (7/21) or epicardial (9/21) myocardium in non-PAH group. The absolute values of left ventricular global peak circumferential strain (LVGPCS), left ventricular global peak longitudinal strain (LVGPLS) and right ventricular global peak longitudinal strain in PAH group were smaller than those in healthy subjects ( P<0.05). The absolute values of LVGPCS and LVGPLS in non-PAH group were smaller than those in healthy subjects ( P<0.05). In PAH group, mean pulmonary artery pressure of RHC was correlated with several FT parameters ( P<0.05), especially left ventricular global peak radial strain ( r=-0.807, P=0.009) and LVGPCS ( r s=0.817, P=0.007). Conclusions:Myocardial injury can be seen in PTA patients. And LGE in the IPs and LGE in the mid-wall or epicardial myocardium is more common in PTA patients with PAH. LVGPCS and LVGPLS can early indicate left heart dysfunction in PTA patients without PAH.
