Objectives This study sought to investigate the relationship between age, sex and alterations in levels of % carbohydrate-deficient transferrin (%CDT) and gamma-glutamyl transferase (GGT) in patients admitted with alcohol dependence. Methods The study retrospectively enrolled 187 patients who were diagnosed with alcohol dependence according to the Diagnostic and Statistical Manual of Mental Disorders-Fourth edition (DSM-IV) and were admitted into a closed ward in Hallym University Hangang Sacred Heart Hospital from 2009 to 2012 and Hallym University Kangnam Sacred Heart Hospital from 2012 to 2017. Demographic factors (age, sex) and biochemical markers [%CDT, GGT, mean corpuscular volume (MCV), aspartate transferase (AST), alanine transferase (ALT)] were collected by reviewing medical records. Alterations in the levels of %CDT and GGT in different groups for each demographic factor were compared after correcting for confounding variables (age, initial %CDT, GGT, MCV, AST, ALT). Results Decreased %CDT and GGT were observed during the period of abstinence after admission. The normalization period for %CDT increased with age, while the normalization period for GGT was longer in female patients. Conclusions These results suggest that alcohol-dependent patients that vary in age have different alterations in %CDT, while different sexes have different alterations in GGT. Age and sex can be potential indicators of treatment response after abstinence in patients with alcohol dependence. Further studies are needed to evaluate the relationship between these factors with regards to physiological and hematological changes in alcohol dependence.

The purpose of this study was to investigate the possibility of Inonotus obliquus as an functional resource. To assess the effects of Inonotus obliquus in culturing method by using unpolished rice in 15non-insulin dependent diabetes mellitus persons, we examined changes of hematological and chemical variables, DM indices content in serum during the Inonotus obliquus supplementation. GOT, GPT concentrations were significantly decreased. But TIBC content was significantly increased. Fasting glucose level during Inonotus obliquus supplementation was decreased respectively. These results show that modest dose of Inonotus obliquus in culturing method by using unpolished rice supplementation can decrease fasting blood glucose level without any changes in health indices and nutrition status of the non-insulin dependent diabetes mellitus person. These results indicated that Inonotus obliquus in culturing method by using unpolished rice diet is effective therapeutic regimen for the control of metabolic derangements in diabetes mellitus. Also, the results imply that Inonotus obliquus in culturing method by using unpolished rice can be used as possible functional food materials. However, large amounts of Inonotus obliquus in culturing method by using unpolished rice showed be used cautiously application.

Recently, as the male silkworm pupae, bee pupae have the potential that strengths men's vitality on vascular endothelial nitric oxide in endothelial cells. Especially we prepared alcohol extract of pupae of bumblebee, native bee named Hobakbul, Bombus ignitus. The alcohol extract of pupae of B. ignitus was administered to rats at doses of 0, 0.04, 0.2, 1 or 2 g/kg as a single oral dose. There were no observed clinical signs or deaths related to treatment in all the groups tested. Therefore, the approximate lethal dose of the alcohol extract B. ignitus pupae was considered to be higher than 2 g/kg in rats. Mild decreases in body weight gain in male were observed dose-dependently within B. ignitus pupae alcohol extract treated groups in dose response manner over 2 weeks. Throughout the administration periods, no significant changes in diet consumption, ophthalmologic findings, clinical pathology (hematology, clinical chemistry and coagulation) or gross pathology were detected. Minor changes in male and female rats were found in hematological parameters for all or partial of B. ignitus pupae extract treated groups but all the changes observed were within the physiological range. From these results, it was concluded that there was no-evidence of specific toxicity related to the ingestion of alcohol extract of B. ignitus pupae.

Purpose: To compare the efficacy and toxicity of gemcitabine versus docetaxel in a second-line setting of nonsmall cell lung cancer (NSCLC) patients previously treated with platin-based combination chemotherapy. Materials and Methods: We retrospectively evaluated the medical records of 57 patients treated with single agent gemcitabine or docetaxel in second-line setting of advanced NSCLC who received one prior platinum-based therapy. Results: The mean age was $56.7{\pm}8.39$ years with 55 (96.5%) males and two (3.5%) females. Forty of them received docetaxel and 17 gemcitabine. The mean number of chemotherapy cycles was $6.8{\pm}4.0$ in the gemcitabine group, while it was $4.6{\pm}3.0$ in the docetaxel group. Overall response rates were 8% and 12% (P=0.02) for gemcitabine and docetaxel, respectively. The median survival time was 22 versus 21 months for gemcitabine and docetaxel, respectively. The median times to progression were 8 and 5 months. There was no difference between the two groups in terms of incidence of adverse affects (40% vs 47.1%). All of the hematological side effects were grade 1/2. No major toxicity was encountered necessitating stopping the drug for either group. Conclusions: Treatment with gemcitabine demonstrated clinically equivalent efficacy with a significantly improved safety profile compared with those receiving docetaxel in the second-line setting for advanced NSCLC in this study. Based on these results, treatment with gemcitabine should be considered a standard treatment option for second-line NSCLC.

An experiment was conducted for 80 days to determine the effect of feeding and starvation on the survival, growth, gonad-somatic index (GSI), hepato-somatic index (HSI), viscera index (LSI), the morphometric changes and hematological parameter in a cultured catfish, Silurus asotus. The survival and growth of the starved group was lower than those of the fed group during the experiment. Starvation resulted in retardation of growth, which provides examples of the reduction of final body weight, growth rate of body weight, specific growth rate and condition factor, whereas the fed group continued to grow and remained in good condition. Blood analysis (cortisol, glucose, aspartate aminotransferase, alanine aminotransferase, red blood cell and hemoglobin) showed significant differences between the fed and starved groups at the end of the experiment. These results suggest that all nutritional parameters used for starvation and feeding in this study appear to be a useful index of nutritional status in the cultured catfish.

Objective: To investigate the clinical effects of whole brain radiotherapy concomitant with targeted therapy for brain metastasis in non-small cell lung cancer (NSCLC) patients with chemotherapy failure. Materials and Methods: Of the 157 NSCLC patients with chemotherapy failure followed by brain metastasis admitted in our hospital from January 2009 to August 2012, the combination group (65 cases) were treated with EGFR-TKI combined with whole brain radiotherapy while the radiotherapy group (92 cases) were given whole brain radiotherapy only. Short-term effects were evaluated based on the increased MRI in brain 1 month after whole brain radiotherapy. Intracranial hypertension responses, hematological toxicity reactions and clinical effects of both groups were observed. Results: There were more adverse reactions in the combination group than in radiotherapy group, but no significant differences were observed between the two groups in response rate (RR) and disease control rate (DCR) (P>0.05). Medium progression free survival (PFS), medium overall survival (OS) and 1-year survival rate in combination group were 6.0 months, 10.6 months and 42.3%, while in the radiotherapy group they were 3.4 months, 7.7 months and 28.0%, respectively, which indicated that there were significant differences in PFS and OS between the two groups (P<0.05). Additionally, RPA grading of each factor in the combination group was a risk factor closely related with survival, with medium PFS in EGFR and KRAS mutation patients being 8.2 months and 11.2 months, and OS being 3.6 months and 6.3 months, respectively. Conclusions: Whole brain radiotherapy concomitant with target therapy is favorable for adverse reaction tolerance and clinical effects, being superior in treating brain metastasis in NSCLC patients with chemotherapy failure and thus deserves to be widely applied in the clinic.

The level and activity of critical regulatory proteins in cells are tightly controlled by several tiers of post-translational modifications. HIF-1α is maintained at low levels under normoxia conditions by the collaboration between PHD proteins and the VHL-containing E3 ubiquitin ligase complex. We recently identified a new physiologically relevant mechanism that regulates HIF-1α stability in the nucleus in response to cellular oxygen levels. This mechanism is based on the collaboration between the SET7/9 methyltransferase and the LSD1 demethylase. SET7/9 adds a methyl group to HIF-1α, which triggers degradation of the protein by the ubiquitin-proteasome system, whereas LSD1 removes the methyl group, leading to stabilization of HIF-1α under hypoxia conditions. In cells from knock-in mice with a mutation preventing HIF-1α methylation (Hif1α^KA/KA), HIF-1α levels were increased in both normoxic and hypoxic conditions. Hif1α^KA/KA knock-in mice displayed increased hematological parameters, such as red blood cell count and hemoglobin concentration. They also displayed pathological phenotypes; retinal and tumor-associated angiogenesis as well as tumor growth were increased in Hif1α^KA/KA knock-in mice. Certain human cancer cells exhibit mutations that cause defects in HIF-1α methylation. In summary, this newly identified methylation-based regulation of HIF-1α stability constitutes another layer of regulation that is independent of previously identified mechanisms.
