Objective To assess the application effect of the catheter management software on the management of Indwelling urinary catheter in the Emergency intensive care unit (EICU). Methods A prospective control study of targeted surveillance of catheter-associated urinary tract infection was conducted from January 2014 to December 2015 in EICU. The patients were divided into two groups. The patients in control group (131 patients) were treated from January 1, 2014 to December 31, 2014 and received routine catheter management, and the patients in test group (135 patients) were treated from January 1, 2015 to December 31, 2015, and received catheter management by software. The catheter management software was developed and applied, and the process specification which collaborated with the software was established. The quality of the catheter management including the omission rate of the catheter management, the rate of urinary catheter-associated urinary tract infections (CAUTI) and the rate of catheter used etc were evaluated after the software's application. Results Through software applications, the omission rate of the catheter management, the omission rate of urine drainage bag replacementand the omission rate of urinary catheter replacement in test group were significantly lower than those in control group:0 vs. 36.64%(48/131), 0 vs. 15.27%(20/131) and 0 vs. 9.92%(13/131), P<0.01 or<0.05. The performance rate of catheter daily management in test group was significantly higher than that in control group: 99.26%(134/135) vs. 64.12%(84/131), P<0.01. The rate of CAUTI in test group was significantly lower than that in control group: 1.90‰ vs. 9.16‰, χ2=4.843, P=0.028. The rate of catheter used in test group was significantly lower than that in control group: 60.74%(82/135) vs. 73.28%(96/131), P<0.01. Conclusions The development and the establishment of the management software can improve the rate of implement, and declinethe rate of CAUTI.

OBJECTIVETo investigate the therapeutic effect of mustard seed on allergic contact dermatitis (ACD) in mice and explore the mechanism.

METHODSEighteen BALB/c mice were randomly divided into normal control group, model group and mustard seed group. The mice in the normal control group and model group were fed with normal chow, and those in mustard seed group were given 5% mustard seed mixed in the chow. Three weeks later, ACD was induced on the ear using 2, 4-dinitrofluorobenzene. After 24 h, the swelling of the ear was examined, and the rats were sacrificed to collect the ear tissue ears and blood for histopathological and immunohistochemical examinations, RT-PCR and enzyme-linked immunosorbent assay.

RESULTSIn mice with ACD, feeding with mustard seeds significantly lessened the ear swelling, improved the tissue histopathology, lowered the number of infiltrating Langerhans cells, and reduced the expressions of IL-1β, TNF-α and IL-6 mRNA in the ear, but did not cause significant changes in serum levels of IL-4, IFN-γ and IL-17.

CONCLUSIONMustard seed inhibits ACD in mice possibly by suppressing the expressions of IL-1β, TNF-α and IL-6 mRNA and inhibiting Langerhans cell migration in the epidermis.

OBJECTIVETo investigate the role of NLRP3 inflammasome in imiquimod-induced psoriasis-like inflammation in mice and the therapeutic effects of mustard seed (Sinapis Alba Linn).

METHODSThirty BALB/c mice were randomized equally into blank control group (fed with normal forage and treated with vehicle), model group (fed with normal forage and treated with 5% imiquimod cream), and experimental group (fed with 5% mustard seed forage and treated with 5% imiquimod cream). RT-PCR was used to detect the mRNA expression of NLRP3, ASC, caspase-1, and caspase-11. Immunohistochemistry was performed to determine the expression and distribution of ASC and caspase-1. ELISA was used to test the serum levels of interleukin-1β (IL-1β) and IL-18.

RESULTSCompared with the blank control group, the mice with imiquimod-induced psoriasis-like inflammation showed significantly increased NLRP3, ASC, caspase-1, and caspase-11 mRNA expressions, ASC and caspase-1 protein expressions , and serum levels of IL-1β and IL-18 (P<0.05). These changes were obviously attenuated by feeding the mice with mustard seed.

CONCLUSIONNLRP3 inflammasome is involved in imiquimod-induced psoriasis-like inflammation in mice, and mustard seed may suppress the inflammation induced by IL-1β and IL-18 through down-regulating the expression of NLRP3 inflammasome.

Objective To study the effect of early entreat nutrition (EN) standardized treatment on optimization of blood glucose control and prognosis in acute respiratory distress syndrome (ARDS) patients with mechanical ventilation (MV). Methods Forty-two patients with MV of ARDS admitted to Huzhou First Municipal People's Hospital from April 2015 to March 2017 were enrolled. April 1st, 2016 was taken as the time node, the patients treated from April 1st, 2015 to March 31st, 2016 were assigned in the control group (n = 20), while the patients treated from April 1st, 2016 to March 31st, 2017 were included in the experimental group (n = 22). The patients in experimental group were given conventional treatment, in 24-48 hours after admission gastrointestinal decompression was stopped and early EN was begun through a nasointestinal tube; the patients in control group received conventional treatment and routine EN (given 48 hours after admission). The differences in nutritional support indexes, the blood glucose variability indexes and the prognostic related indicators were compared between the two groups. Results Compared with the control group, the initiation time for EN tolerance, first defecation time, time of reaching target feeding amount were significantly earlier in the early EN standardized treatment process management [time of initial EN tolerance (hours): 106.82±42.84 vs. 157.29±56.76, first defecation time (hours): 71.29±23.43 vs. 104.69±26.94, time of reaching target feeding amount (days): 6.24±1.25 vs. 9.86±2.36], the proportions of EN/EN+parenteral nutrition (PN) and the nasointestinal tube feeding reaching the standard on 7 days in experimental group were significantly increased [the proportion of EN/EN+PN:98.69% vs. 78.69%, the nasointestinal tube feeding reaching standard: 68.18% (15/22) vs. 45.00% (9/20)], average level of blood glucose (GLUave), maximum value of blood glucose (GLUmax), standard deviation of blood glucose (GLUsd), coefficient of variation of blood glucose (GLUcv), hyperglycemia incidence, incidence of multiple organ dysfunction syndrome (MODS), 28-day mortality were significantly decreased [GLUave (mmol/L): 9.4±2.6 vs. 11.5±3.9, GLUmax (mmol/L): 14.19±2.36 vs. 16.26±4.89, GLUsd (mmol/L): 4.86±1.27 vs. 6.87±2.46, GLUcv: (49.86±6.32)% vs. (59.95±5.81)%, hyperglycemia incidence: 59.09% (13/22) vs. 80.00% (16/20), incidence of MODS: 59.09% (13/22) vs. 80.00% (16/20), 28-day mortality: 36.36% (8/22) vs. 45.00% (9/20)], minimum value of blood glucose (GLUmin) was significantly increased (mmol/L: 5.86±2.32 vs. 4.18±1.86), invasive MV time was significantly shorted (hours:156.82±26.84 vs. 169.93±32.34) with statistically significant differences (all P < 0.05). Early EN could also improve the patient's pulmonary oxygenation function. Since 9 days of disease course, the oxygenation index (PaO2/FiO2) in the experimental group was significantly higher than that of the control group [mmHg (1 mmHg = 0.133 kPa): 256.97±18.63 vs. 239.82±21.72, P = 0.068], but there was no significant difference in the length of ICU stay (days: 13.9±3.6 vs. 14.8±3.4, P > 0.05). Conclusion The early EN standardized treatment process management can improve the nutritional status, decrease blood sugar fluctuations, and further benefit the improvement of the prognosis of ARDS patients with MV.
