A 67-year-old male visited Pusan Veterans Hospital due to general weakness and weight loss for 6 months. Physical examination showed non-tender 4 finger breaths sized splenomegaly and both inguinal and cervical lymphadenopathy. The white blood cell count was 25,300/uL with 91% morphologically mature lymphocytes. Bone marrow aspirate revealed hypercellularity with 74.5% lymphocytes morphologically similar to peripheral lymphocytes. The immunophenotpying study of lymphocytes displayed the phenotype of CD19(+), CD20(+), HLA-DR(+), sIg(+) but CD5(-). We concluded that this patients's diagnosis is CD 5 negative B-cell chronic lymphocytic leukemia.

OBJECTIVE: To observe the changes in protein expression induced by botulinum toxin A (BoNT-A) injection and to characterize the molecular and cellular action of mechanisms of BoNT-A injection on skeletal muscles using proteomic elements as biomarkers. METHODS: BoNT-A was injected into left gastrocnemius muscles of 12 Sprague-Dawley rats (2 months of age) at a dosage of 5 units/kg body weight. For the controls same volume of normal saline was injected to right gastrocnemius muscle of each rat. Muscle samples were obtained at 4 time points (3 rats per time point): 3, 7, 14, and 56 day post-injection. To reveal the alterations in muscle protein, we performed 2-dimensional electrophoresis (2DE) and compared Botox group and normal saline group at each time point. Altered protein spots in 2DE were identified using matrix-assisted laser desorption/ionization-time-of-flight mass spectrometer (MALDI-TOF MS) proteomics analysis. RESULTS: Compared with normal saline group, 46 protein spots showed changed protein expression. Twelve protein spots demonstrated increased volume and 34 protein spots demonstrated decreased volume. Among spots of decreased volume, 17 spots showed statistically significant differences. Thirty-eight identified proteins were associated with alterations in energy metabolism, muscle contractile function, transcription, translation, cell proliferation, and cellular stress response. CONCLUSION: BoNT-A gives influences on muscle contractile function and energy metabolism directly or indirectly besides neurotoxic effects. Proteomic expression provides better understanding about the effect of BoNT-A on skeletal muscle.

BACKGROUND/AIMS: Various predictive factors for peginterferon alpha and ribavirin therapy in chronic hepatitis C have been reported, but the effect of adherence to therapy has not been established. We investigated how adherence affects the sustained virologic response (SVR). METHODS: We analyzed 92 chronic hepatitis C patients receiving peginterferon alpha and ribavirin combination therapy. Patients were first identified as having either genotype 1 or genotype non-1 infection and then categorized into three groups according to their adherence to the treatment protocol: (1) patients who received > or =80% of the recommended dosage of both peginterferon alpha and ribavirin for > or =80% of the intended duration of therapy, (2) patients who received <60% of the recommended dosage of both peginterferon alpha and ribavirin for <60% of the intended duration of therapy, and (3) patients who were not included in either group 1 or 2. RESULTS: The rates of early virologic response, end of treatment response, and SVR differed significantly with the degree of adherence to the treatment. The SVRs of genotype 1 patients were 86.7%, 26.7%, and 66.7% in groups 1, 2, and 3, respectively (P=0.003), and those of genotype non-1 were 100%, 16.7%, and 88.9%, respectively (P<0.001). CONCLUSIONS: Adherence to therapy is a key factor in achieving an SVR. Supportive strategies to improve adherence will increase overall SVR rates.

BACKGROUND/AIMS: We compared the recurrence of hepatocellular carcinoma (HCC) and the survival of patients who received radiofrequency ablation (RFA) after transarterial chemoembolization (TACE) with patients treated with TACE or RFA alone. METHODS: This study included 201 patients with HCC, who were consecutively enrolled at Seoul St. Mary's Hospital between December 2004 and February 2010. Inclusion criteria were a single HCC < or = 5.0 cm or up to three HCCs < or = 3.0 cm. We used a propensity score model to compare HCC patients (n = 87) who received RFA after TACE (TACE + RFA) with those who received TACE (n = 71) or RFA alone (n = 43). RESULTS: The median follow-up period was 33.3 months (range, 6.8 to 80.9). The TACE + RFA group showed significantly lower local recurrence than the RFA or TACE groups (hazard ratio [HR], 0.309; 95% confidence interval [CI], 0.130 to 0.736; p = 0.008; and HR, 0.352; 95% CI, 0.158 to 0.787; p = 0.011, respectively). The overall survival was significantly better in the TACE + RFA group compared to the RFA group (HR, 0.422; 95% CI, 0.185 to 0.964; p = 0.041). However, the survival benefit was not different between the TACE + RFA and TACE groups (p = 0.124). Subgroup analysis showed that among patients with a tumor size < 3 cm, the TACE + RFA group had significantly better long-term survival than those in the TACE or RFA groups (p = 0.017, p = 0.004, respectively). CONCLUSIONS: TACE + RFA combination treatment showed favorable local recurrence and better overall survival rates in early-stage HCC patients. Patients with tumors < 3 cm are likely to benefit more from TACE + RFA combination treatment. Additional studies are needed for the selection of suitable HCC patients for TACE + RFA treatment.

Annals of Rehabilitation Medicine 2014;38(3):317-326
OBJECTIVE: To compare transverse abdominis (TrA) contractility in stroke patients with hemiparesis and healthy adults using musculoskeletal ultrasonography. METHODS: Forty-seven stroke patients with hemiparesis and 25 age-matched healthy control subjects participated in this study. Stroke patients were divided into three groups on the basis of their degree of ambulation. Group A consisted of 9 patients with wheelchair ambulation, group B of 23 patients with assisted ambulation, and group C of 15 patients with independent ambulation. Inter-rater reliability regarding ultrasonographic measurement of abdominal muscle thickness in the control group was assessed by two examiners. The TrA contraction ratio (TrA contracted thickness/TrA resting thickness) was measured during abdominal drawing-in maneuver and was compared between the patients and the control group and between the ambulation groups. RESULTS: The inter-rater reliability ranged from 0.900 to 0.947. The TrA contraction ratio was higher in the non-paretic side than in the paretic side (1.40+/-0.62 vs. 1.14+/-0.35, p<0.01). The TrA contraction ratio of the patient group was lower in the non-paretic side as well as in the paretic side than that of the control group (right 1.85+/-0.29, left 1.92+/-0.42; p<0.001). No difference was found between the ambulation regarding the TrA contraction ratio. CONCLUSION: The TrA contractility in hemiparetic stroke patients is significantly decreased in the non-paretic side as well as in the paretic side compared with that of healthy adults. Ultrasonographic measurement can be clinically used in the evaluation of deep abdominal muscles in stroke patients.

BACKGROUND: This retrospective study analyzed the causes of failure in the management process from the identification of brain-dead potential organ donors to actual donation in Korea over the past 5 years. METHODS: Data of 8,120 potential brain deaths reported to the Korea Organ Donation Agency were used, including information received at the time of reporting, donation suitability evaluation performed by the coordinator after the report, and data obtained from interviews of hospital medical staff and the donor's family. RESULTS: From January 2012 to December 2016, the total number of brain-dead potential organ donors in Korea was 8,120, of which 2,348 (28.9%) underwent organ procurement surgery with designated recipients. While the number of transplant donors has increased over time, the ratio of transplant donors to medically suitable brain-dead donors has decreased. The common causes of donation failure included donation refusal (27.6%), non-brain death (15.5%), and incompatible donation (11.6%); 104 potential donors (7.8%) were unable to donate their organs because they were not pronounced brain dead. CONCLUSION: The rate of successful organ donation may be increased by analyzing the major causes of failure in the brain-dead organ donation management process and engaging in various efforts to prevent such failures.

BACKGROUND/AIMS: According to recent prevalence of hepatitis A virus (HAV) infection, acute liver failure (ALF) due to HAV infection is observed frequently in parallel. The aim of this study was to elucidate the clinical, laboratory, and pathologic features of patients who have undergone emergency liver transplantation (LT) due to fulminant HAV infection. METHODS: Clinical, laboratory, and pathologic data of 11 transplant recipients with anti-HAV IgM-positive ALF between December 2007 and May 2009 were analyzed, and compared with data of 10 recipients who underwent LT for the management of ALF due to other causes. RESULTS: The median age of the patients with HAV-related ALF was 34 years (range: 15-43 years). The levels of hemoglobin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and creatinine were higher and the level of bilirubin was lower in the HAV-related ALF group than in the other group (P=0.005, 0.001, 0.001, 0.010, and 0.003, respectively). The time from the onset of initial symptoms to the development of encephalopathy was shorter in the HAV-related ALF group than in the other group (median 5 days, range: 4-13 days; P<0.001). In patients with HAV-related ALF, laboratory findings and clinical prognostic parameters including the Acute Liver Failure Study Group prognostic index, King's College criteria, and model for endstage liver disease (MELD) and Child-Pugh scores were not associated with the grade of hepatic encephalopathy or time of progression to encephalopathy. CONCLUSIONS: The results of this study indicate that the clinical condition of patients with HAV-related ALF requiring emergency LT aggravates rapidly. Prognostic parameters are not sufficient for discriminating transplant candidates in patients with fulminant hepatitis A.

BACKGROUND/AIMS: Enhanced replication of hepatitis C virus (HCV) is well described in the setting of moderate to severe immunosuppression. The aims of this retrospective study were to determine the incidence of enhanced HCV replication in hepatocellular carcinoma (HCC) patients undergoing transarterial chemolipiodolization (TACL) and to identify the factors associated with enhanced replication of HCV. The clinical pattern of enhanced HCV replication was compared with hepatitis B virus (HBV) reactivation during TACL. METHODS: This study enrolled 49 anti-HCV-seropositive patients who were diagnosed with HCC between January 2005 and December 2010 and who underwent TACL using epirubicin and/or cisplatin with consecutive HCV RNA copies checked. For comparison, 46 hepatitis B surface antigen1-positive patients with HCC who were treated with TACL were also enrolled. The frequency, associated factors, and clinical outcomes of enhanced HCV replication were analyzed and compared with those of HBV reactivation during TACL. RESULTS: Enhanced replication of HCV occurred in 13 (26.5%) of the 49 anti-HCV-seropositive patients during TACL. Of these 13 patients, 4 developed hepatitis, but none of the subjects developed decompensation due to the hepatitis. No significant clinical factors for enhanced HCV replication during TACL were found. Compared with HBV reactivation, the frequency of hepatitis attributed to enhanced HCV replication was significantly lower than that for HBV reactivation (8.2% vs. 23.9%, P=0.036). CONCLUSIONS: TACL can enhance HCV replication; however, the likelihood of hepatitis and decompensation stemming from enhanced HCV replication was lower than that for HBV reactivation in patients undergoing TACL.

OBJECTIVE:
The aim of this study is to summarize preclinical studies on herbal medicines used to treat cancer cachexia and its underlying mechanisms.
METHODS:
We searched four representing databases, including PubMed, EMBASE, the Allied and Complementary Medicine Database, and the Web of Science up to December 2016. Randomized animal studies were included if the effects of any herbal medicine were tested on cancer cachexia. The methodological quality was evaluated by the Collaborative Approach to Meta-Analysis and Review of Animal Data from Experimental Studies (CAMARADE) checklist.
RESULTS:
A total of fourteen herbal medicines and their compounds were identified, including Coptidis Rhizoma, berberine, Bing De Ling, curcumin, Qing-Shu-Yi-Qi-Tang, Scutellaria baicalensis, Hochuekkito, Rikkunshito, hesperidin, atractylodin, Sipjeondaebo-tang, Sosiho-tang, Anemarrhena Rhizoma, and Phellodendri Cortex. All the herbal medicines, except curcumin, have been shown to ameliorate the symptoms of cancer cachexia through anti-inflammation, regulation of the neuroendocrine pathway, and modulation of the ubiquitin proteasome system or protein synthesis.
CONCLUSIONS
This study showed that herbal medicines might be a useful approach for treating cancer cachexia. However, more detailed experimental studies on the molecular mechanisms and active compounds are needed.

OBJECTIVETo study various experts' opinions on the defifinition and diagnosis of blood stasis in China.
METHODSWe e-mailed the selected experts to explain the purpose of the study and to invite them to participate and asked them to name a time for the investigator to call them. Eight experts and fifive organizations were interviewed in the research community investigating blood stasis in China.
RESULTSSix main categories emerged from the interviews: (1) blood stasis concepts; (2) blood stasis-related biomarkers; (3) methods of diagnosing blood stasis; (4) drugs for promoting blood circulation and dissipating stasis; (5) blood stasis-related diseases; and (6) blood stasis-related societies. The consensus among the interviewed experts was that the defifinition of blood stasis is rather complicated and that there is no gold standard marker for detecting blood stasis.
CONCLUSIONSThis paper acquired experts' opinions on the defifinition and diagnosis of blood stasis in order to establish a modern concept of blood stasis. This paper also developed a diagnostic tool and diagnostic indices for blood stasis and identifified biological indices and pathologic mechanisms related to blood stasis, which might be of great reference value in future blood stasis standardization research.
