Annexin-1 (ANX1) is a 37 kDa protein that is induced and secreted by glucocorticosteroid hormone. The secreted ANX1 has been believed to exert its function by binding to its putative rnembrane receptor. In this report we demonstrate that ANXl receptor (ANX1R) signal blocks the interleukin-1B (IL-1B) receptor signal pathway in human peripheral blood mononuclear cells (PBMCs). When PBMCs were treated with both IL-1B (100 ng/ml) and PMA (10 ng/ml) in the absence or presence of dexamethasone for 5 days, dexamethasone (100 nM) suppressed lymphocyte proliferation to 24% of the control. However addition of anti-ANX1 polyclonal antibody of 1:200 and 1:1,000 dilution to this system induced recovery of proliferation to 80% and 40%, respectively, when compared to the control. In the mixed lymphocyte reaction, dexamethasone suppressed lymphocyte proliferation to 9% of that of control when stimulated with IL-1B (100 ng/ml) and phorbol myristate acetate (10 ng/ml). Addition of anti-ANX1 polyclonal antibody (1:1,000) to this system also recovered the proliferation to 20% of that of the control system. In the ANX1 receptor induction experiment using flow cytometry, ANX1 receptor expression on lymphocytes, CD4+ T cells, CD8+ T cells and monocytes increased depending on the externally added IL-1B ranging from 10 to 1,000 ng/ml. From these results, it is evident that dexamethasone induces ANX1 secretion into the culture medium and anti-ANX1 polyclonal antibody abolishes the effects of dexamethasone. Furthermore these results imply that extracellular ANX1 exerts its effects by binding to the receptor on the cell membrane and the activated signal(s) of ANX1R block IL-1B receptor signal in the lymphocytes.

BACKGROUND: The goal of this study was to analyze the process and characteristics of withholding or withdrawal of life support (WLS) in Korean intensive care units (ICUs). METHODS: This was a single-centered retrospective analysis of patients who died in the ICUs of a tertiary hospital in Korea from January to December 2012. WLS informed consents and clinical data were analyzed. RESULTS: Of 285 deaths during the study period, informed consents for WLS were obtained from 228 patients (80.0%). All WLS decisions were made by family members after the patient's loss of decision-making capacity. Decisions were made most frequently by the patient's son (50.6%). Patients in the WLS group were older than those in the non-WLS group, and older age was associated with the WLS decision. Thirty-seven patients (16.2%) died within one hour of WLS approval, and 182 patients (79.8%) died on the day of WLS approval. The most frequently withheld life support modality was chest compression (100%), followed by defibrillation (95.9%) and pacemaker insertion (63.3%). CONCLUSIONS: Aggressive and invasive life support measures were those most frequently withheld or withdrawn by decision-makers in Korean ICUs. The most common proxy was the son, rather than the spouse.

3.The Effects of General Characteristics, Lifestyle and Nutrients on Obesity, Serum Lipids and C-Reactive Protein for Adults.
Korean Journal of Rehabilitation Nursing 2008;11(2):99-106
PURPOSE: The purpose of this study was to identify predictors of obesity, serum lipids and CRP in Korean adults. The predictors of obesity and serum lipids were the subject's general characteristics, life style, eating habit and nutrients. The predictors of CRP were the subject's general characteristics, life style, eating habit, nutrients, obesity and serum lipids. METHOD: 115 subjects who had visited the health examination center at a hospital participated in the study. The data analysed with descriptive analysis, ANOVA, Chi-square test, Pearson correlation coefficient and multiple regression. RESULT: Sex, married, eating out (4< or =/w), eating out (2-3/w) and age (61< or =) were anticipated variable on BMI(R2=0.488). Sex and overeating (2-3/w) were anticipated variable on body fat(R2=0.218). Drink (4-6/w), age (51-60), sex, vegetable fat and Systolic BP were anticipated variable on total cholesterol (R2=0.217). Age (51-60), vegetable fat and unmarried were anticipated variable on LDL (R2=0.180).Sex was anticipated variable on HDL and Triglyceride (R2=0.054, 0.192). Breakfast (1-3/w) and meal (2/d) were anticipated variable on CRP (R2=0.1268). CONCLUSION: It is thought that decreasing eating out and overeating might be important to prevent obesity. It is thought that decreasing drinking and fat eating might be important to improve serum lipids. It is thought that eating breakfast might be important to decrease CRP.

4.Comparison of Clinical Outcomes between Rebound Hyperthermia and Non-Rebound Hypertherma Groups in Postcardiac Arrest Syndrome Patients Undergoing Targeted Temperature Management
Journal of Korean Critical Care Nursing 2023;16(3):99-108
Purpose:
: This retrospective study aims to provide basic data for intervention to improve clinical outcomes and identify the characteristics of the rebound hyperthermia (RHG) and non-rebound hyperthermia (NRHG) groups by checking body temperature in patients with post-cardiac arrest syndrome.Method : The study involved 118 patients who completed target temperature management (TTM) in an acute-care unit. Data were analyzed for frequency, percentages, mean, standard deviation, median, and quartiles, and compared using the chi-squared test and Mann–Whitney U-test.
Results:
: Rebound hyperthermia (RH) was observed in 74 (62.7%) patients, predominantly male (69.5%), with an average age of 64.54 ± 15.98, and a body mass index of 23.22 ± 4.75kg/m2 (overweight). Hypertension (50%) was the most common co-morbidity, followed by diabetes and heart disease (33.1%). Neuron-specific enolase levels were higher in the NRHG 24, 48, and 72 hours after recovery of spontaneous circulation (p = .037, p< .001, p= .008). The APHCHE Ⅳ was also higher in the NRHG (p< .001). RH occurred 25.49 (7.28–52.96) hours after TTM completion, lasting for 2 (1–3) hours. Temperature reduction strategies included notifying doctors, administering antipyretics, and nursing intervention, with the latter being the most common at 94.6%. Half of the subjects in the RHG and 77.3% in the NRHG fell into cerebral performance categories 3, 4, and 5 (p= .003).
Conclusion
: RH is more likely a body mechanism related to CPR and TTM than a result of pathogenic infection. Therefore, we require an active intervention for hyperthermia, and a patient-specific nursing intervention protocol.

A 44-year-old man was cutting an outer plate of a ship, at a depth of 25 m below sea level. Following a sudden explosion, he was discovered unconscious and was carried to the surface by other divers. There was no evidence of vital signs upon arrival at the hospital. Postmortem computed tomography, which was performed prior to autopsy, revealed massive pneumocephalus in the brain, pneumohemothorax, diffuse lung contusions with multiple traumatic lung cysts, air-fluid level in the cardiac chamber of the chest, and pneumoperitoneum in the abdomen. Postmortem external examination showed a circular abrasion on the jaw, diffuse subcutaneous emphysema, and contusion in the right upper arm. An internal examination revealed intravascular air bubbles in all four chambers of the heart, and diffuse pulmonary trauma including contusion, laceration, and multiple traumatic cysts. Blast injury to the chest, and air embolism due to the underwater explosion were established as the underlying cause of death.

PURPOSE: To evaluate the long-term outcomes of fascial sling operation conducted at multicenters in Korea. MATERIALS AND METHODS: 564 patients, who underwent fascial sling operation for stress urinary incontinence, between December 1996 and May 2001, at 10 institutions in Korea, were included in this study. They were all followed up for a period of at least 2 years. History taking, a physical examination, and urodynamic studies, including Valsalva leak point pressure (VLPP), were conducted before the operation. Postoperative symptoms and satisfaction were assessed using a questionnaire. The 269 (47.7%), 266 (47.2%) and 29 (5.1%) patients underwent operations with autologous rectus fascia, cadaveric allograft fascia and autologous fascia lata, respectively. RESULTS: The mean follow up period was 43.6 months, ranging from 24 to 77 months. Stress urinary incontinence was cured in 485 (86.0%) patients and improved in 31 (5.5%). In autologous fascia group, 252 (84.6%) patients were cured and 18 (6.0%) improved; whereas, in allograft fascia group 233 (87.6%) patients were cured and 13 (4.9%) improved. 253 (84.9%) patients with autologous fascia and 228 (85.7%) patients with allograft fascia were satisfied, making a total of 481 patients (85.3%) that were satisfied with the operation. According to the fascia length and preoperative VLPP value, there were no differences in the success and patient satisfaction rates. There were 197 (34.9%) patients with preoperative urge urinary incontinence, and 92 (46.7%) of these were either cured or improved postoperatively. However, de novo urge urinary incontinence was noted in 8 patients (1.4%). CONCLUSIONS: Our results suggest that the long-term outcome of fascial sling operation for the treatment of stress urinary incontinence was satisfactory.

PURPOSE: Many investigators suggested that changes in hormonal environment in the postmenopausal women functionally or histologically effect the clitoris and vagina. We investigated the mechanism of female se xual dysfunction occurring in the decreased hormonal status, and aimed to establish and experimental base for the hormone replacement in postmenopausal women to correct sexual dysfunction. MATERIALS AND METHODS: Twenty mature female New Zealand white rabbits were randomly divided into three groups; control group, oophorectomy group, estrogen replacement group after oophorectomy. Nitric oxide synthase (NOS) activity and the degree of expression of neuronal NOS (nNOS) and endothelial NOS (eNOS), collagen content in clitoral tissues were analysed. RESULTS: nNOS and eNOS were significantly increased in the oohporectomized group while decreased in the estrogen replacement group (p<0.01). NOS activity showed the similar pattern of change (p<0.05). Oophorectomy induced a significant increase in collagen content, while the ratio of smooth muscle content was increased significantly after the estrogen replacement (p<0.01). CONCLUSIONS: Estrogen deficiency induces collagen synthesis and decreases the content of smooth muscle in clitoris, resulting in a structural relaxation difficulty. We believe that NOS becomes more active to improve the relaxation difficulty and that hormone replacement helps to restore the normal state of smooth muscle relaxation. Considering these findings, we suggest that estrogen down-regulates NOS and its activity.

An unusual case of homicide of a 21-year-old man who was smothered with a hot steam towel by his mother and a pastoress in the name of exorcism. Homicidal smothering in adults is rare, but does occur when the victims are not capable of defending themselves in situations such as chronic illness, old age, drug intoxication or when restrained by other people. In this case, distinct facial scalding was a clue to smothering with a hot steam towel.

A renal angiomyolipoma (AML) is an unusual benign tumor that is composed of adipose tissue, smooth muscle, and abnormal blood vessels. AMLs can occur sporadically or can be associated with tuberous sclerosis. A ruptured renal AML may manifest as lift-threatening hypovolemic shock or sudden death. Herein, the authors present an autopsy case of traumatic rupture of a renal AML in a patient with tuberous sclerosis.
