1.Two cases of neck region Kimura's disease.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2015;29(11):1042-1043
Kimura's disease is a rare, benign, slow-growing chronic inflammatory swelling with a predilection for the head and neck region and is almost always with peripheral blood eosinophilia and elevated serum IgE levels. It is endemic in Asian males and rare in Western people. Surgical excision of the lesion is the first line therapy. Drug and radiation therapy have to be considered for the refractory lesions.

Objective To evaluate the effect of airway pressure release ventilation (APRV) in patients with acute lung injury/acute respiratory distress syndrome (ALI/ARDS), to evaluate the extent of ventilator-induced lung injury (VILI), and to explore its possible mechanism. Methods A prospective study was conducted in the Department of Critical Care Medicine of the First Hospital of Hebei Medical University from December 2010 to February 2012. The patients with ALI/ARDS were enrolled. They were randomly divided into two groups. The patients in APRV group were given APRV pattern, while those in control group were given lung protection ventilation, synchronized intermittent mandatory ventilation with positive end-expiratory pressure (SIMV+PEEP). All patients were treated with AVEA ventilator. The parameters such as airway peak pressure (Ppeak), mean airway pressure (Pmean), pulse oxygen saturation (SpO2), mean arterial pressure (MAP), heart rate (HR), central venous pressure (CVP), arterial blood gas, urine output (UO), the usage of sedation and muscle relaxation drugs were recorded. AVEA ventilator turning point (Pflex) operation was used to describe the quasi-static pressure volume curve (P-V curve). High and low inflection point (UIP, LIP) and triangular Pflex volume (Vdelta) were automatically measured and calculated. The ventilation parameters were set, and the 24-hour P-V curve was recorded again in order to be compared with subsequent results. Venous blood was collected before treatment, 24 hours and 48 hours after ventilation to measure lung surfactant protein D (SP-D) and large molecular mucus in saliva (KL-6) by enzyme linked immunosorbent assay (ELISA), and the correlation between the above two parameters and prognosis on 28 days was analyzed by multinomial logistic regression. Results Twenty-six patients with ALI/ARDS were enrolled, and 22 of them completed the test with 10 in APRV group and 12 in control group. The basic parameters and P-V curves between two groups were similar before the test. After 24 hours and 48 hours, mechanical ventilation was given in both groups. The patients' oxygenation was improved significantly, though there were no significant changes in hemodynamic parameters. The Pmean (cmH2O, 1 cmH2O = 0.098 kPa) in APRV group was significantly higher than that in control group (24 hours: 24.20±4.59 vs. 17.50±3.48, P < 0.01; 48 hours: 18.10±4.30 vs. 15.00±2.59, P < 0.05). After ventilation for 24 hours, the ratio of patients with increased Vdelta in APRV group was higher than that in control group (90% vs. 75%), but without statistical difference (P > 0.05). The SP-D level (μg/L) in serum in APRV group showed a tendency of increase (increased from 19.70±7.34 to 27.61±10.21, P < 0.05), in contrast there was a tendency of decrease in control group (decreased from 21.83±7.31 to 16.58±2.90, P > 0.05), the difference between the two groups was statistically significant (P < 0.05). After 48-hour ventilation, SP-D in APRV group was decreased, but no change was found in control group, and no significant difference was found as compared with that of the control group (16.45±8.17 vs. 17.20±4.59, P > 0.05). There was no significant difference in serum KL-6 between the two groups before and after ventilation. The SP-D and KL-6 levels in serum were unrelated with 28-day survival rate of the patients. The odds ratio (OR) of SP-D were 0.900 [95% confidence interval (95%CI) = 0.719-1.125], 1.054 (95%CI = 0.878-1.266), 1.143 (95%CI = 0.957-1.365), and the OR of KL-6 were 1.356 (95%CI = 0.668-2.754), 0.658 (95%CI = 0.161-2.685), 0.915 (95%CI = 0.350-2.394) before the test, 24 hours and 48 hours after ventilation (all P > 0.05). Conclusions APRV was similar to lung protective ventilation strategy in oxygenation and improvements in the lung mechanics parameters. APRV with a higher Pmean can recruit alveolar more effectively, and it had no impact on hemo-dynamics, but might exacerbate VILI.

[ ABSTRACT] AIM: To observe the effect of microRNA-19a ( miR-19a) on the lipid catabolism of hepatocyte LO2, and to explore the potential mechanism.METHODS: miR-19a was over-expressed or silenced by transfection of miR-19a mimics or miR-19a inhibitor into LO2 cells, then the mRNA level of miR-19a was detected by real-time PCR.The potential target of miR-19a was found by the method of bioinformatics through internet website.The effect of miR-19a on the 3’ UTR of peroxisome proliferator-activated receptorα(PPARα) was measured by dual luciferase reporter assay, and the protein level of PPARαand its 2 major downstream rate-limiting enzymes involved in lipid catabolism, acyl-coenzyme a dehydrogenase (ACADM) and carnitine palmitoyltransferase 1A ( CPT1A), were detected by Western blotting.Mean-while, the effect of miR-19a on the generation of ketone body was measured by beta-hydroxybutyric acid (β-OHB) detec-tion assay.RESULTS:The mRNA level of miR-19a was dramatically elevated by the transfection of miR-19a mimics, and sharply decreased by the transfection of miR-19a inhibitor (P<0.05).PPARαwas found as a potential target of miR-19a, and dual luciferase reporter assay and Western blotting confirmed the regulatory effect of miR-19a on the expression of PPARα, with the protein level changes of ACADM and CPT1A.miR-19a mimics down-regulated, while miR-19a inhibitor up-regulated the concentration ofβ-OHB in LO2 cells (P<0.05).CONCLUSION:miR-19a regulates the lipid catabo-lism of hepatocytes by targeting the PPARαand its 2 downstream rate-limiting enzymes.

Objective To investigate safety and efficiency of anti-coagulation therapy in patients with high-risk of bleeding and multiple organ dysfunction syndrome (MODS) during continuous veno-venous hemofiltration (CVVH). Meth-ods Forty patients with high-risk bleeding MODS during CVVH in our hospital were divided into heparin-free group (A group) and low-dose heparin group (B group). Blood coagulation function, platelets counts, blood urea nitrogen, serum creati-nine, PaO2/FIO2 and Apache Ⅱ scores in two groups were tracked before treatment and 24 h, 48 h after treatment. Filter lifespan, median ventilation time, ICU admission time and bleeding complications were observed. Results (1)There was significant difference in levels of blood urea nitrogen, serum creatinine, PaO2/FIO2 and ApacheⅡscores at 24 h, 48 h after treatment between in low-dose heparin group and those in heparin-free group (P<0.05). (2)Levels of activated partial thromboplastin time(APTT), thrombin time (TT) were prolonged. Platelets count were significantly lower at 24 h after treat-ment than that before treatment in low-dose heparin group. Levels of APTT, TT and platelets count had no changes with pro-longed time of CVVH therapy.(3)Average ventilation time, ICU admission time were obviously shorter in low-dose heparin group than that in heparin-free group. Filter lifespan was significant longer in low-dose heparin group than that in heparin-free group, (P<0.05).(4)Bleeding in skin and mucosa was observed in 1 case in low-dose heparin group without other se-vere bleeding complications. Conclusion The results of monocentric study show that low dose of heparin ensure smooth op-eration of CVVH in patients with MODS and high-risk bleeding. The clinical application is safe and efficient.
