Objectives: This study is aimed to evaluate the protective effects of GGX on lung injury of Chronic Obstructive Lung Disease (COPD) mice model. Materials and Methods: C57BL/6 mice were challenged with lipopolysaccharide (LPS) and cigarette smoke extract (CSE) and then treated with vehicle only (Control group), dexamethasone 3 mg/kg (Dexa group), gam-gil-tang 200 mg/kg (GGT group), GGX 100, 200, and 400 mg/kg (GGX group). After sacrifice, its bronchoalveolar lavage fluid (BALF) or lung tissue was analyzed with cytospin, Enzyme-Linked Immunosorbent Assay (ELISA), real-time polymerase chain reaction (PCR) and hematoxylin & eosin (H&E), and Masson's trichrome staining. Results: In the COPD model, GGX significantly inhibited the increase of neutrophils, TNF-𝛼, IL-17A, CXCL-1, MIP2 in BALF and TNF-𝛼, IL-1𝛽, IL-10 mRNA expression in lung tissue. It also decreased the severity of histological lung injury. Conclusion: This study suggests the usability of GGX for COPD patients by controlling lung tissue injury.

The purpose of this study is to provide basic data for effective management and prevention of chronic diseases and secondary complications as elderly spinal cord injuries(SCI). The subjects were 200 spinal cord injuries admitted to S hospital from April, 2013 to April, 2018. We investigated the occurrence of chronic diseases and secondary complication through medical records. The results showed that SCI were affected chronic diseases and secondary complications over 50years. The prevalence of chronic diseases and secondary complications over 50 years of age had the odds ratio 11.8 times higher in hypertension and 6.7 times diabetes mellitus. Secondary complications had the odds ratio Osteoporosis 7.5 times, Pneumonia 5.2 times, and central pain 0.4 times. We suggest that continuous management and service of chronic diseases and secondary complications of elderly SCI are necessary. It will be necessary to expand the target population and to study various characteristics including.

Pain is a complex symptom consisting of a sensation underlying potenial disease and associated emotional state. Acute pain is a reflex biological response to injury, in contrast, chronic pain consists of pain of a mininum of 6 months duration and associates with physical, emotional past experience, economic resources of the patient, family and society. Moreover, chronic pain is characterized by physiological affective and behavioral responses that are quite different than those of acute pain. The different type of stimuli exciting pain receptor are mechanical, thermal and chemical stimli and chronic pain are concerned with three of all stimli. The major three components of pain central(Analgesia) system in the brain and spinal cord are 'periaqueductal gray area of the mesencephalon', 'the raphe magnus nucleus' and 'pain inhibitory complex located in the dorsal horns of the spinal cord'. But unfortunately, the central biochemical mechanisms of chronic pain are not clearly defined. To proper management of chronic pain, comprehensive urderstanding as a psychosomatic aspect and multidisciplinary therapeuti-team approach must be emphasized.

Previous reports showed that Compound Astragalus and Salvia miltiorrhiza extract (CASE), which was mainly composed of astragalosides, astragalus polysaccharide and salvianolic acids, inhibited hepatic fibrosis by mediating transforming growth factor-${\beta}$ (TGF-${\beta}$)/Smad signaling. Our aim was to examine the effects of CASE on D-galactosamine (D-GalN) treated liver injury in mice and carbon tetrachloride ($CCl_4$)-induced liver fibrosis in rats. CASE was administered to mice with D-GalN-induced liver injury and to rats with $CCl_4$-induced liver fibrosis, respectively. Liver injury was routinely evaluated by relative liver weight, serum levels of ALT, AST, hyaluronic acid (HA), hepatic malondialdehyde (MDA) content, superoxide dismutase (SOD) activity, hydroxyproline (HYP) and histopathologic changes. Treatment of mice with CASE (60, 120, and 240 mg/kg, ig) significantly lowered ALT, relative liver weight, and MDA levels when compared with D-GalN treated mice. CASE (120, 240 mg/kg) significantly lowered ALT, AST, HA, HYP, and MDA levels against $CCl_4$ treated rats. Decreased SOD level was reversed with CASE treatment. Upon histopathological examination, CASE treatment had significantly inhibitory effect on the progression of hepatic fibrosis in rats. These results indicate that CASE might be effective in treatment and prevention of acute and chronic hepatic injury due to its antioxidant activity.

Objective : Balloon kyphoplasty is a minimally invasive procedure that is mainly performed for refractory pain due to osteoporotic compression fractures. The purpose of this study was to evaluate the results of balloon kyphoplasty performed at different times after an injury. Methods : In this retrospective study, the records of 99 patients who underwent one level of balloon kyphoplasty between January 2005 and December 2007 were reviewed. The patients were divided into three groups : 21 patients treated within 3 weeks of an injury (the acute group), 49 treated within 3 weeks to 2 months of an injury (the subacute group), and 29 patients treated at more than 2 months after an injury (the chronic group). Clinical outcomes were assessed using a visual analogue scale (VAS). In addition, modified MacNab's grading criteria was used to assess the subjective patient outcome. The radiology findings, including vertebral height restoration and procedure related complications, were analyzed based on the different time intervals after the injury. Results : Patients in all three groups achieved marked pain relief in terms of the VAS within 7 days of the procedure. Good or excellent results were achieved by most patients in all three groups. However, the height restoration, the main advantage to performing a balloon kyphoplasty, was not achieved in the chronic group. Moreover, evidence of complications including cement leakage was observed significantly less frequently in the subacute group compared to the other two groups. Conclusion : Although balloon kyphoplasty is an effective treatment for osteoporotic compression fractures, with regard to pain relief, the subacute stage appears to be optimal for treating patients with a balloon kyphoplasty in terms of achieving the best outcomes with minimal complications.

Background: Kidney injury molecule-1 (KIM-1) is known as a good ancillary marker of acute kidney injury (AKI) and its expression has also been observed in acute rejection and chronic graft dysfunction. We tested usefulness of KIM-1 as an indicator of acute and chronic renal graft injury by correlating KIM-1 expression with renal graft function and histology. Methods: A total of 133 zero-time biopsies and 42 follow-up biopsies obtained within 1 year posttransplantation were selected. Renal tubular KIM-1 staining was graded semiquantitatively from 0 to 3 and the extent of staining was expressed as the ratio of KIM-1 positive/CD10 positive proximal tubules using Image J program. Results: KIM-1 was positive in 39.8% of zero-time biopsies. KIM-1 positive cases were predominantly male and had received grafts from donors with older age, deceased donors, and poor renal function at the time of donation, compared with KIM-1 negative cases. KIM-1 expression showed correlation with delayed graft function and acute tubular necrosis. In comparison of KIM-1 expression between stable grafts (n=23) and grafts with dysfunction (n=19) at the time of repeated biopsy, the intensity/extent of KIM-1 staining and renal histology at zero-time did not differ significantly between the two groups. Histologically, KIM-1 expression was significantly increased with both acute and chronic changes of glomeruli, tubules and interstitium, peritubular capillaritis, and arteriolar hyalinosis. Conclusions: KIM-1 can be used as an ancillary marker of AKI and a nonspecific indicator of acute inflammation and tubulointerstitial fibrosis. However, KIM-1 expression at zero-time is not suitable for prediction of long-term graft dysfunction.

Ankle sprains are among the most common injuries sustained during athletic activities and daily life. Acute ankle sprain is usually managed conservatively with functional rehabilitation but the failure of conservative treatment leads to the development of chronic ankle instability. The development of repetitive ankle sprains and persistent symptoms after injury has been termed chronic ankle instability. Acute ankle sprains and chronic ankle instability require a careful evaluation to detect other comorbidities, such as subtalar instability, osteochondral defect, peroneal tendinopathy, tarsal coalition, os trigonum, flexor hallucis longus tendinitis, calcaneus anterior process fracture, and neural injuries. For the successful treatment of acute ankle sprains and chronic ankle instability, the treatment of comorbidity lesions should be performed first.

Epidural hematoma (EDH) can sometimes be life-threatening, although small-volume EDHs can resolve spontaneously like other intracranial hematomas. However, in rare cases, EDH can transform into a chronic form instead of disappearing. In contrast to subdural hematoma, there is no agreed-upon definition or treatment of chronic EDH. A 41-year-old male patient with acute EDH in the bilateral paravertical area due to partial rupture of the sagittal sinus was operated first, and then remnant contralateral hematoma was treated conservatively. One month after surgery, he showed hemiparesis, and brain imaging revealed chronic EDH at the location of the remnant acute hematoma. We performed surgery again to treat chronic EDH through a large craniotomy. Although many cases of EDH are self-limited, clinicians must keep in mind that some cases of EDH, especially those of venous origin and arising in young people, can become chronic and require surgical treatment.

Background: This study aimed to evaluate the impact of the treatment modality on post-procedural acute kidney injury (AKI) and other clinical outcomes in patients with advanced chronic kidney disease who underwent surgical or transcatheter aortic valve replacement (AVR). Methods: A total of 147 patients with advanced chronic kidney disease (stage 3 to 5) who underwent isolated surgical AVR (SAVR group; n=70) or transcatheter AVR (TAVR group; n=77) were retrospectively studied. Postprocedural AKI was defined according to the RIFLE definition (an acronym corresponding to the risk of renal dysfunction, injury to the kidney, failure of kidney function, loss of kidney function, and end-stage kidney disease). Factors associated with postoperative complications and mortality were analyzed using multivariable logistic regression models and Cox proportional hazard models. Results: Postprocedural AKI occurred in 17 (24.3%) and 6 (7.8%) patients in the SAVR and TAVR groups, respectively (p=0.006). Multivariable analyses demonstrated that the SAVR group had higher risks of AKI (odds ratio [OR], 5.63; 95% confidence interval [CI], 1.85-17.73; p=0.002) and atrial fibrillation (OR, 16.65; 95% CI, 4.44-62.50; p<0.001), whereas the TAVR group had a higher risk of permanent pacemaker insertion (OR, 5.67; 95% CI, 1.21-26.55; p=0.028). The Cox proportional hazard models showed that the occurrence of AKI, contrary to the treatment modality, was associated with overall survival. Conclusion: In patients with chronic kidney disease, the risk of postprocedural AKI might be higher after SAVR than after TAVR.
