Patients at the same pathological stage of esophageal cancer (EC) that received the same surgical therapy by the same surgeon may have distinct prognoses. The current study aimed to explore the possibility of differentially-expressed microRNAs (miRNAs) underlying this phenomenon. Samples were collected from EC patients at the same tumor node metastasis (TNM) stage but with different prognoses. Paracancerous normal tissues were taken as controls. The specimens were histopathologically analyzed. Differentially-expressed miRNAs were analyzed using real-time quantitative reverse transcription polymerase chain reaction. Compared with patients with poor prognosis, those with good prognosis exhibited 88 two-fold or more than two-fold increased miRNA fragments and 4 half-decreased miRNAs. The most noticeably up-regulated miRNAs included hsa-miR-31, hsa-miR-196b, hsa-miR-652, hsa-miR-125a-5p, hsa-miR-146b, hsa-miR-200c, hsa-miR-23b, hsa-miR-29a, hsa-miR-186, hsa-miR-205, hsa-miR-376a, hsa-miR-410, hsa-miR-532-3p, and hsa-miR-598, whereas the most significantly-downregulated miRNAs were hsa-let-7e, hsa-miR-130b, and hsa-miR-103. EC patients at same TNM stage but with different prognoses show differentially-expressed miRNAs.

This research developed an intravenous (IV) vancomycin dosing nomogram based on the clinical pharmacokinetic data of Korean adult patients. Total 99 pairs of steady-state peak and trough serum concentrations of vancomycin were obtained from 73 adult patients in a tertiary general hospital. Serum vancomycin concentrations were determined to assess the appropriateness of initial vancomycin dosing. Only 47.2% of the cases were within therapeutic range. To characterize the clinical pharmacokinetics (PK) of vancomycin, PK parameters including elimination rate constant ( $K_{e}$) half-life( $T_{1}$2/), clearance (C $l_{van}$), volume of distribution ( $V_{d}$) were calculated by using one-compartment, first order pharmacokinetic equations. PK parameters were evaluated based on the differences of patients'renal function and age. Regression analysis showed a significant correlation between C $l_{van}$ and $C_{cr}$ (C $l_{van}$ = -1.89+0.914 $C_{cr}$ , r=0.763) and between $K_{e}$ and $C_{cr}$ , ( $K_{e}$=-0.0037+0.00139 $C_{cr}$ =0.724). The relationship between $K_{e}$ and $C_{cr}$ , and the mean $V_{d}$ were utilized for developing the nomogram to individualize the initial dosing regimen of vancomycin for the patients with various degrees of renal functions. The nomogram may be used as an efficient tool to determine safe and effective doses of vancomycin for the Korean adult patients.nts.nts.nts.s.nts.

Objectives: The aims of this study are 1) to determine if GAST is a better indicator in predicting ovarian response to COH compared with patient's age or basal FSH level and 2) to evaluate its role in detecting abnormal ovarian response. Design: Prospective study in 118 patients undergoing IVF-ET using GnRH-a short protocol during May-September 1995. Materials and Methods: After blood sampling for basal FSH and estradiol $(E_2)$ on cycle day two, 0.5ml (0.525mg) GnRH agonist ($Suprefact^{(r)}$, Hoechst) was injected subcutaneously. Serum $E_2$ was measured 24 hours later. Initial $E_2$ difference $({\Delta}E_2)$ was defined as the change in $E_2$ on day 3 over the baseline day 2 value. Sixteen patients with ovarian cyst or single ovary or incorrect blood collection time were excluded from the analysis. The patients were divided into three groups by ${\Delta}E_2$; group A (n=30):${\Delta}E_2$<40 pg/ml, group B (n=52): 40 pg/ml${\leq}{\Delta}E_2$<100 pg/ml, group C (n=20): ${\Delta}E_2{\leq}100$ pg/ml. COH was done by GnRH agonist/HMG/hCG and IVF-ET was followed. Ratio of $E_2$ on day of hCG injection over the number of ampules of gonadotropins used ($E_2hCGday$/Amp) was regarded as ovarian responsiveness. Poor ovarian response and overstimulation were defined as $E_2$ hCGday less than 600 pg/ml and greater than 5000 pg/ml, respectively. Results: Mean age $({\pm}SEM)$ in group A, B and C were $33.7{\pm}0.8^*,\;31.5{\pm}0.6\;and\;30.6{\pm}0.5^*$, respectively ($^*$: p<0.05). Mean basal FSH level of group $A(11.1{\pm}1.1mlU/ml)$ was significantly higher than those of $B(7.4{\pm}0.2mIU/ml)$ and C $(6.8{\pm}0.4mIU/ml)$ (p<0.001). Mean $E_2hCGday$ of group A was significantly lower than those of group B or C, i.e., $1402.1{\pm}187.7pg/ml,\;3153.2{\pm}240.0pg/ml,\;4078.8{\pm}306.4pg/ml$ respectively (p<0.0001). The number of ampules of gonadotropins used in group A was significantly greater than those in group B or C: $38.6{\pm}2.3,\;24.2{\pm}1.1\;and\;18.5{\pm}1.0$ (p<0.0001). The number of oocytes retrieved in group A was significantly smaller than those in group B or C: $6.4{\pm}1.1,\;15.5{\pm}1.1\;and\;18.6{\pm}1.6$, respectively (p<0.0001). By stepwise multiple regression, only ${\Delta}E_2$ showed a significant correlation (r=0.68, p<0.0001) with $E_2HCGday$/Amp, while age or basal FSH level were not significant. Likewise, only ${\Delta}E_2$ correlated significantly with the number of oocytes retrieved (r=0.57, p<0.001). All four patients whose COH was canceled due to poor ovarian response belonged to group A only (Fisher's exact test, p<0.01). Whereas none of 30 patients in group A (0%) had overstimulation, 14 patients among 72 patients (19.4%) in group B and C had overstimulation (Fisher's exact test, p<0.01). Conclusions: These data suggest that initial $E_2$ difference after GAST may be a better prognostic indicator of ovarian response to COH than age or basal FSH level. Since initial $E_2$ difference demonstrates significant association with abnormal ovarian response such as poor ovarian response necessitating cycle cancellation or overstimulation, GAST may be helpful in monitoring and consultation of patients during COH in IVF-ET cycle.

목 적 : Tei 지수는 전반적인 심기능을 양적으로 쉽게 측정할 수 있는 장점이 있으나 심박동수, 전부하, 후부하에 영향을 받을 수 있으며 같은 심장 cycle에서 측정하기 어려운 단점이 제시되고 있다. 이에 반해 modified Tei 지수는 TDI을 이용하여 같은 cycle 내에서 측정 가능하기 때문에 기존의 Tei 지수의 단점을 보완할 수 있는 새로운 방법으로 제시되고 있다. 방 법 : 가와사키병의 급성기 환아 48명을 두 군(modified Tei 지수가 0.37 미만인 24명을 1군, modified Tei 지수가 0.37 이상인 24명을 2군), 그리고 열이 없는 정상 소아 30명을 대조군인 3군으로 나누어 연구를 시행하였다. 혈액 검사, TDI, 고식적인 심초음파를 시행하였다. 수축기 심근 속도, 초기 이완기(E') 심근 속도, 그리고 후기 이완기(A') 심근 속도와 조직 이동을 심저, 심중간부, 심첨에서 측정하였다. Ejection fraction(EF), Tei 지수, modified Tei 지수를 계산하였다. 결 과 : 백혈구수와 CRP는 2군에서 대조군에 비해 유의하게 높았다. 좌심실 기저부 수축기 심근 조직 이동, 초기 이완기 및 후기 이완기 심근 조직 이동이 2군에서 대조군에 비해 유의하게 감소하였다. Modified Tei 지수와 심실 기저부의 수축기 심근조직 이동(r=0.331), 초기 이완기(E') 심근 조직 이동(r=0.296), 그리고 후기 이완기(A') 심근 조직 이동(r=0.266)이 음의 상관관계를 보였다. Modified Tei 지수가 증가할수록 ESR(r=0.561)과 CRP(r=0.427)가 유의하게 증가하는 양의 상관관계가 보였다. EF과 Tei 지수는 정상이었다. 결 론 : 가와사키병에서 TDI를 이용한 modified Tei 지수는 EF이나 Tei 지수로 구별되지 않았던 심기능 이상을 발견하는데 매우 도움이 되는 유용한 지표로 생각된다.

Background: Lung cancer is one of the commonest and most lethal cancers throughout the world. The majority of the patients present at advance stage and are not suitable for curative intent treatment. Even among patients with localized disease, there has been underutilization of curative treatment modalities. The aim of this study was to analyze the radical treatment utilization rates in patients with non small cell lung cancer (NSCLC) treated at our centre. Materials and Methods: We analyzed case records of 104 patients with a pathologically confirmed diagnosis of NSCLC having stage 1-3B disease who were treated at our centre over last 3 years, to assess the utilization of curative treatment modalities i.e. surgery or radical radiotherapy. Results: The median age of this cohort was 58 years. Out of 104 patients only 33 (31.7%) received curative intent treatment, 14 undergoing curative resection and 19 receiving radical doses of radiotherapy. The baseline characteristics of both the groups (with or without radical treatment) were not different. Major factors associated with underutilization with curative treatment were progressive disease or loss of follow up after chemotherapy and inappropriate use of TKI and/or palliative radiotherapy in patients with stage 1-3B disease. Patients who did not receive radical treatment had inferior PFS and OS than those who received radical treatment. Conclusions: In our practice we observed gross underutilization of curative intent treatment modalities in patients with NSCLCs which is associated with inferior survival.

Objectives: This study aimed to investigate the characteristics of early maladaptive schemas and their associations with clinical symptoms in patients with schizophrenia. Methods: Forty-eight patients with schizophrenia, 49 patients with major depressive disorder, and 50 healthy controls completed the Young Schema Questionnaire and symptom measures including the Brief Psychiatric Rating Scale-Expanded (BPRS-E). Results: The schizophrenia group had significantly higher scores than the healthy controls and lower scores than the depression group in most schemas. Compared with healthy controls, the schizophrenia group exhibited higher scores in 10 schemas, i.e., mistrust, social isolation, failure, dependence, vulnerability to harm, enmeshment, insufficient self-control, subjugation, emotional inhibition, and negativity schemas (all p<0.001). Moreover, vulnerability to harm, enmeshment, subjugation, and negativity schemas were correlated with total scores of the BPRS-E (0.37≤r≤0.43, all p<0.05). Regarding the five BPRS domains, emotional deprivation schema showed significant relationships with negative (r=0.50, p=0.005) and disorganization (r=0.39, p=0.033) symptoms, while no schemas showed correlations with positive symptoms. Conclusion: These results suggest that most schemas in patients with schizophrenia pertain to impaired autonomy and performance as well as disconnection and rejection domains and may improve our understanding and the treatment of schizophrenia from a perspective of schema therapy focused on these domains.

Objective: To explore the sensitivity of gastric cancer cells to chemotherapy drugs in elderly patients and its correlation with cyclooxygenase-2 (COX-2) expression in cancer tissue. Materials and Methods: Forty-three elderly patients with gastric cancer (observation group) and 31 young patients with gastrointestinal tumors (control group) who were all diagnosed by pathology and underwent surgery in the 89th Hospital of Chinese People's Liberation Army were selected. Drug sensitivity testing of tumor cells in primary culture was carried out in both groups using a methyl thiazolyl tetrazolium (MTT) method, and the expression of COX-2 and the factors related to multi-drug resistance (MDR) in cancer tissue were assessed by immunohistochemistry. Results: The inhibition rates (IR) of vincristine (VCR), 5-fluorouracil (5-FU), oxaliplatin (L-OHP), mitomycin (MMC) and epirubicin (eADM) on tumor cells in the observation group were dramatically lower than in the control group, with statistical significance (P<0.05 or P<0.01). The positive rates of COX-2, glutathione s-transferase-${\pi}$ (GST-${\pi}$) and P glycoprotein (P-gp) expression in cancer tissue in the observation group were all higher than in control group (P<0.05), while that of DNA topoisomerase $II{\alpha}$ ($TopoII{\alpha}$) expression lower than in the control group (P<0.01). In the observation group, COX-2 expression in cancer tissue had a significantly-positive correlation with GST-${\pi}$ and P-gp (r=0.855, P=0.000; r=0.240, P=0.026), but a negative correlation with $TopoII{\alpha}$ (r=-0.328, P=0.002). In the control group, COX-2 expression in cancer tissue was only correlated with P-gp positively (r=0.320, P=0.011). Bivariate correlation analysis displayed that COX-2 expression in cancer tissue in the observation group had a significantly-negative correlation with the IRs of 5-FU, L-OHP, paclitaxel (PTX) and eADM in tumor cells (r=-0.723, P=0.000; r=-0.570, P=0.000; r=-0.919, P=0.000; r=-0.781, P=0.000), but with hydroxycamptothecine (HCPT), VCR and 5-FU in the control group (r=-0.915, P=0.000; r=-0.890, P=0.000; r=-0.949, P=0.000). Conclusions: Gastric cancer cells in elderly patients feature stronger MDR, which may be related to high COX-2 expression.

Purpose: The robotic system for surgery was introduced to gastric cancer surgery in the early 2000s to overcome the shortcomings of laparoscopic surgery. The more recently introduced da Vinci $Xi^{(R)}$ system offers benefits allowing four-quadrant access, greater range of motion, and easier docking through an overhead boom rotation with laser targeting. We aimed to identify whether the $Xi^{(R)}$ system provides actual advantages over the $Si^{(R)}$ system in gastrectomy for gastric cancer by comparing the operative outcomes. Materials and Methods: We retrospectively reviewed all patients who underwent robotic gastrectomy as treatment for gastric cancer from March 2016 to March 2017. Patients' demographic data, perioperative information, and operative and pathological outcomes were collected and analyzed. Results: A total of 109 patients were included in the $Xi^{(R)}$ group and 179 in the $Si^{(R)}$ group. Demographic characteristics were similar in both groups. The mean operative time was 229.9 minutes in the $Xi^{(R)}$ group and 223.7 minutes in the $Si^{(R)}$ group. The mean estimated blood loss was 72.7 mL in the $Xi^{(R)}$ group and 62.1 mL in the $Si^{(R)}$ group. No patient in the $Xi^{(R)}$ group was converted to open or laparoscopy, while 3 patients in the $Si^{(R)}$ group were converted, 2 to open surgery and 1 to laparoscopy, this difference was not statistically significant. Bowel function was resumed 3 days after surgery, while soft diet was initiated 4 days after surgery. Conclusions: We found no difference in surgical outcomes after robotic gastrectomy for gastric cancer between the da Vinci $Xi^{(R)}$ and da Vinci $Si^{(R)}$ procedures.
