Objective : There were few reports on the treatment of Adult-onset Still's disease and Diffuse cerebral dysfunction. This oriental medical treatment shows the possibility of healing Adult-onset Still's disease and Diffuse cerebral dysfunction, therefore we announce this. Methods : The acupuncture, herbal medicine, herbal acupucture(Jahageo, Nockyong) therapies were applied for treating this patient's chief symptom(chest discomfort, palpitation, rigidity, mentality change, global aphasia, dysphagia, coughing and sputum) Results : 1. Adult-onset Still's disease is a rare systemic inflammatory disorder of unknown etiology, characterised by salmon-colored rash, intermittent spiking high fever, arthralgia and variety of systemic features. This is one type of Juvenile arthritis. 2. Diffuse cerebral dysfunction is an anoxic-ischemic encephalopathy, and most cause of this is the hypoxia caused by hypotention or respiratory distress. 3. After oriental medical treatments, his chief symptoms were improved. Conclusion : The more study about oriental medical treatment on Adult-onset Still's disease and Diffuse cerebral dysfunction is needed.

Background: Recent studies show that mitophagy, the autophagy-dependent turnover of mitochondria, mediates pulmonary epithelial cell death in response to cigarette smoke extract (CSE) exposure and contributes to the development of emphysema in vivo during chronic cigarette smoke (CS) exposure, although the underlying mechanisms remain unclear. Methods: In this study, we investigated the role of mitophagy in the regulation of CSE-exposed lung bronchial epithelial cell (Beas-2B) death. We also investigated the role of a phosphodiesterase 4 inhibitor, roflumilast, in CSE-induced mitophagy-dependent cell death. Results: Our results demonstrated that CSE induces mitophagy in Beas-2B cells through mitochondrial dysfunction and increased the expression levels of the mitophagy regulator protein, PTEN-induced putative kinase-1 (PINK1), and the mitochondrial fission protein, dynamin-1-like protein (DRP1). CSE-induced epithelial cell death was significantly increased in Beas-2B cells exposed to CSE but was decreased by small interfering RNA-dependent knockdown of DRP1. Treatment with roflumilast in Beas-2B cells inhibited CSE-induced mitochondrial dysfunction and mitophagy by inhibiting the expression of phospho-DRP1 and -PINK1. Roflumilast protected against cell death and increased cell viability, as determined by the lactate dehydrogenase release test and the MTT assay, respectively, in Beas-2B cells exposed to CSE. Conclusion: These findings suggest that roflumilast plays a protective role in CS-induced mitophagy-dependent cell death.

Transient peripheral eosinophilia occurs in several disorders, such as allergic diseases, cancer, and parasitic infections. However, in most cases, their presence is not accompanied by tissue destruction or organ dysfunction. In certain disease states, eosinophils can accumulate in any organ in the body and cause tissue destruction as a result of the eosinophil infiltration or the toxic effects of the degranulated proinflammatory products. Idiopathic hypereosinophilic syndrome is a rare disorder characterized by persistent eosinophilia of an unknown origin, usually associated with a dysfunction of organs such as the heart, lung, skin, and nervous system. Idiopathic hypereosinophilic syndrome usually has an indolent course over a period of several months. However, in some cases, they have grave symptoms if vital organs such as heart and lung are infiltrated. Here we report a case of idiopathic hypereosinophilic syndrome presenting acute pulmonary edema involving the heart, bone marrow, and lung with a review of the relevant literatures.

The purpose of this study was to analyze the effect of acute respiratory training feedback upon a change on HRV-Autonomic nervous system in middle-aged women. The research subjects were totally 24 middle-aged women(40-60 years old), were randomly allocated 12 people to the respiratory training group and 12 people to the control group, and then were carried out the acute respiratory training. The feedback exercise in the respiratory training group was conducted for totally 15 minutes. Following the 10-minute breath awareness training according to the expert's guidance, the 5-minute autonomous breathing exercise was implemented. The data analysis was carried out Repeated Measures ANOVA with SPSS WIN 20.0. The conclusions that were obtained through this are as follows. The middle-aged women got significantly higher in SDNN, RMSSD, LF, HF after the acute respiratory training. Compared to the control group. the respiratory training group was indicated to have gotten higher significantly in SDNN, RMSSD, LF, HF. Mean HR and LF/HF were not shown a significant difference in both the main effect of group & period and the interaction effect of group & period. Above of a result the acute respiratory training feedback is effective for SDNN, RMSSD, sympathetic activity, parasympathetic activity in the middle-aged women. Thereby, the respiratory training program improves autonomic nervous system, being considered to be possibly expected the effective value of exercise intervention available for relieving stress and recovering autonomic dysfunction in the middle-aged women.

Background: Extracorporeal membrane oxygenation (ECMO) during severe acute respiratory failure helps to recover the pulmonary function. This study evaluated our experience with veno-venous ECMO in adult patients with acute respiratory failure. Methods: From January 2007 to July 2009, ECMO was used on 54 patients. Of these 54 patients, 7 were placed on veno-venous ECMO for acute respiratory failure. The indications of ECMO were based on the lung dysfunction measured as a $PaO_2/FiO_2$ ratio <100 mm Hg on $FiO_2$ of 1.0, or an arterial blood gas pH <7.25 due to hypercapnia despite the optimal treatment. $EBS^{(R)}$, $Bio-pump^{(R)}$, and Centrifugal Rotaflow $pump^{(R)}$ were used and all cannulations were performed percutaneously via both femoral veins. When the lung function was improved, an attempt was made to wean on ECMO at moderate ventilator settings followed by decannulation. Results: Five of the 7 patients were male and the mean age was $46.3{\pm}18.3$. The causes of acute respiratory failure were 3 cases of pneumonia, 2 near-drownings, 1 pulmonary hemorrhage due to acute hepatic failure and 1 mercury vapor poisoning. The mean support time of ECMO was $17.3{\pm}13.7$ days. Of the 7 patients implanted with ECMO, 5 patients (71%) were weaned off ECMO and 3 patients (43%) survived to hospital discharge after a mean 89.6 hospital days. Conclusion: The early use of ECMO for acute respiratory failure in adults due to any cause is a good therapeutic option for those unresponsive to the optimal conventional treatments.

Objective: The prevalence of metabolic syndrome and type 2 diabetes is increasing worldwide. Mitochondrial dysfunction is known to be involved in insulin resistance and obesity, researches have been increasing highly. Astragali Radix extract (ARE) or its main components have been shown to perform comparably to insulin by significantly reducing blood glucose levels in animal models however, the influence on mitochondrial dysfunction are not well understood. Methods: ARE (0.2, 0.5 and 1.0 mg/ml) or metformin (2.5 mM) were treated in C2C12 after 6 day-differentiation. The expressions of adenosine monophosphate (AMP)-activated protein kinase (AMPK) and phosphorylation AMPK, peroxisome proliferators-activated receptror ${\gamma}$ coactivator $1{\alpha}$ ($PGC1{\alpha}$), nuclear respiratory factors 1 (NRF1), mitochondrial transcription factor (Tfam) and myosin heavy chain were detected with western blotting or polymerase chain reaction analysis. The morphological changes were also investigated. Results: ARE dose dependently increased phosphorylation of AMPK and respectively activated mRNA expressions of $PGC1{\alpha}$, NRF1 and Tfam which are mitochondrial biogenesis regulators. Furthermore, there were some morphologic differences of differentiated cells between ARE treatment and control. Conclusions: This study suggests that ARE has the potential to increase muscle mitochondrial function by activating AMPK and $PGC1{\alpha}$.

Fat embolism syndrome is a collection of respiratory, neurological and cutaneous symptoms and signs associated with trauma and other disparate surgical and medical conditions. The incidence of clinical syndrome is low while the embolization of marrow fat appears to be an almost inevitable consequence of long bone fractures. The pathogenesis is a subject of conjecture and controversy. There are two theories which have gained acceptance(mechanical theory, biochemical theory). Onset of symptom is usually within 12 to 72 hours, but may manifest as early as 6 hours to as late as 10 days. The classic triad of fat embolism syndrome involves pulmonary changes, cerebral dysfunction and petechial rash. The cornerstone of treatment is preventing the stress response, hypovolemia and hypoxia and operative stabilization of fractures. Corticosteroid are the only drugs which have repeatedly shown a positive effect on the prevention and treatment of fat embolism syndrome. We report a case of post-traumatic fat embolism syndrome with severe cerebral involvement without respiratory distress. A 55 years old female had a traffic accident. She sustained pelvic bone fracture and both humerus fracture. Approximately 4 hours after the accident, mental status change developed without a focal neurologic deficits. She had no respiratory symptom and sign. Her brain MRI showed multiple cerebral fat embolism lesion. The patients received supportive treatment with corticosteroid, albumin. Her neurologic status stabilized over several days. After orthopedic surgery, she was discharged 62 days after admission.

A mechanical circulatory support system is a life-saving option for treating acute severe respiratory failure or cardiac failure. There are currently a few types of assist devices and the Twin-Pulse Life Support (T-PLS) system is a kind of pulsatile pump. We report here on three patients with severe life threatening cardiopulmonary dysfunction who had the T-PLS system used as an assist device. The indications for applying the T-PLS system were continuing respiratory or cardiac failure in spite of maximal ventilatory and inotropic support. There were two patients with acute respiratory failure due to infection and one patient with cardiac failure due to acute myocarditis. One respiratory failure patient and one cardiac failure patient survived after applying the T-PLS system for 3 days and 5 days, respectively. The T-PLS system is useful as an assist device and it should be considered before multi-organ failure occurs.

Background : Recent discoveries on the physiology of an erection have demonstrated that the organic causes of impotence are more common, and psychogenic impotence is correspondingly less common than was formally believed. The incidence of sexual dysfunctions in chronic obstructive pulmonary disease (COPD) patients is largely unknown or may be perfunctorily attributed to the associated illness or to aging. This study investigated whether or not the impotence was related to the COPD itself as well as whether or not it nay stem from organic causes in a notable proportion of such patients. Methods : The sexual function was evaluated in 10 COPD patients and 10 normal control subjects. A nocturnal Rigi Scan was performed to evaluate the erectile function of each group. The level of hormones such as the free testosterone, prolactin and thyroid stimulating hormone (TSH) was measured, and a pulmonary function test and arterial blood gas analysis was performed. Results : The time duration and frequency of a penile erection were significantly lower in COPD patients than the controls (p<0.05). In addition, the $PaO_2$ levels correlated with the time duration of the penile erection. Conclusion : These results suggest that COPD is one of the causes of organic erectile dysfunction.

From May 1, 1993 to May 31 1995, the authers studied retrospectively 211 patients who underwent cardiovascular operation with cardiopulmonary bypass(CPB). Because we were interested in new development of ARF(prevalence, mortality rate, and main risk factors), we performed a multivariate statistical analysis about data of patients with preoperative serum creatinine values of less than 1.5 mg/dL. Normal renal function before operation(serum creatinine level less than 1.5 mg/dL) was registered in 198(74%) patients. Of these, 27(14%) patients showed postoperative renal complication, including 20(10%) patients classified as renal dysfunction(serum creatinine level between 1.5 and 2.5 mg/dL) and 7(4%) patients as acute renal failure(serum creatinine level higher than 2.5 mg/dL). The mortality rate was 5.8% in normal patients, 5% in patients with renal dysfunction, and 43% when acute renal failure developed(p=0.036). Indeed, the renal impairment proved to be an independent predictor of mortality(odd ratio 2.52∼11.25), along with cardiovascular(odd ratio 4.20) and respiratory(odd ratio 2.18) complications. Multivariate analysis identified the following variables as independent risk factors for postoperative renal impairment : advanced age(odd ratio 1), need for emergency operation(odd ratio 3.78), low-output syndrome(odd ratio 3.66), respiratory complication(odd ratio 1.30), need for deep hypothermic circulatory arrest(odd ratio 1.4). The 13 patients(7%) with preoperative renal failure showed a significantly higher morbidity and mortality rate than those without renal complications before operation. We concluded that the likelihood of severe renal complications is resonably low in the patients undergoing cardiac operation without preexisting renal dysfunction, but associated mortality remains high. A prominant role of hemodynamic factor in the development of postoperative acute renal failure must be recognized during preoperative, intraoperative, and postoperative periods.
