목적: 다른 소화기계 악성종양에 비하여 위암에서 종양표지자의 역할은 매우 제한적이다. 여러 연구들에서 종양표지자는 예후 및 재발과 밀접한 연관이 있음이 보고되었으나, 종양표지자를 이용한 수술 전 원격전이 예측의 유용성에 관한 보고는 매우 드물다. 대상 및 방법: 2004년부터 2006년까지 본원에서 위암으로 수술을 시행 받은 환자 중 종양 표지자의 비특이적 증가를 초래하는 요인을 가진 환자를 제외한 788명의 환자를 대상으로 수술 전 CEA, CA 19-9와 임상병리학적 특성간에 상관관계를 분석하였다. 결과: CEA 양성여부는 연령, 성별과 같은 종양과 무관한 비특이적 인자에 의해서도 영향을 받으며, 림프절 전이여부와 독립적인 상관관계가 있었으나 종양의 침윤도와는 상관관계가 없었다. 원격전이의 예측에서 CEA는 복막전이나 혈행성 전이와 유의한 상관관계가 없었다. 이에 비해 CA 19-9는 종양의 침윤도 림프절 전이와 각각 독립적인 상관관계를 보였으며, 원격전이 중 복막 전이여부와 유의한 상관관계를 보였다. 특히, 증가 정도에 따라 CA 19-9가 5배 이상 증가 시에 복막전이에 대한 위험도가 유의하게 증가함을 보였다. 결론: CA 19-9는 측정이 간편하고 용이할 뿐만 아니라, 수술 전 비치유인자인 복막전이를 예측하는데 도움을 줌으로써, 이에 따른 환자의 추가적인 검사를 통하여 적절한 치료 방침을 세우는데 임상적으로 유용한 도구라고 판단된다.

목적 : 골육종 환자의 조직과 혈청에서 DNase, RNase, 5'-nucleotidase, alkaline phosphatase 및 amylase 활성도를 측정하여 그 활성도의 변동을 보았고 이들 효소가 골육종의 표지자로 이용될 수 있는지 알아보았다. 대상 및 연구방법 : 골육종 환자의 혈청과 종양조직은 1 2예로부터 얻었으며, 이에 대한 대조조직은 동일 환자의 정상부위에서 채취하였다. 조직 추출액을 얻어서 핵산, 단백함량, 그리고 효소 활성도의 측정에 사용하였다. DEAE-cellulose chromatography에 의해 골육종 조직의 acid DNase, neutral RNase, RNase inhibitor와 단백을 분리하고 그활성도와 단백 함량을 측정하였다. 결과 : 골육종 조직의 acid DNase, RNase, 5'-nucleotidase, alkaline phosphatase 활성도는 유의하게 상승하였고, 효소활성도의 양성율도 높게 나타났다. neutral RNase의 활성도가 특히 높았으며, RNase inhibitor는 neutral RNase와 복합을 이루면서 그 활성도가 유의하게 증가하였다. 혈청 neutral RNase 활성도가 유의하게 상승하였다. DEAE-cellulose column chromatography에 의해 acid DNase는 단일효소로서, 그리고 neutral RNase는 5개의 isozyme으로 분리되었다. 결론 : 이들 효소의 병용이 골육종의 생화학적 표지자로서 이용될 수 있을 가능성을 시사하였다. 또한 혈청 neutral RNase활성도의 측정이 골육종의 생화학적 표지자로서의 역할을 시사하였다. acid DNase와 neutral RNase가 골육종의 발생과 억제과정에 작용하고 있을 가능성을 시사하였다.

해양오염의 진단을 위한 생화학적 오염지표 설정의 기초연구의 일환으로, 오염이 심각한 서해안의 오염지표에 관한 연구에 이어, 남해안의 오염도를 평가하기 위하여 오염도가 적은 동해안 포항의 자연산 넙치를 대조군으로 하여 남해산 양식산 넙치 (Paralichthys olivaceus)의 혈액중의 지질성분을 분석 평가하였다. 남해안의 양식산 넙치의 혈청중의 헤모글로빈의 함량은 포항의 자연산 넙치 대비 각각 $4\~17\%$의 감소현상이 나타나서 헤모글로빈의 파괴가 상달함을 알 수 있었다. 남해안의 양식산 넙치의 혈청중의 중성지질, 총콜레스테롤 및 LDL-콜레스테롤의 함량은 대조군으로 사용한 포항의 자연산 넙치대비 각각 $12\~25\%,\;9\~19\%$ 및 $17\~25\%$나 높았다. 이러한 사실은 해양오염 뿐만 아니라 양식산 넙치의 사료의 과량 투여 및 운동량 부족도 관계할 것으로 판단된다. 남해안의 양식산 넙치의 동맥경화지수 (AI) 및 인지질에 대한 총콜레스테롤의 함량비 (T-Chol/PL ratio)도 대조군으로 사용한 포항의 자연산 넙치 대비 각각$26\~43\%$ 및 $17\~26\%$나 높아서 남해안의 양식산 넙치의 오염도가 심각한 것으로 판단된다. 한편 남해안의 양식산 넙치의 HDL-콜레스테롤의 함량은 대조군으로 사용한 포항의 자연산 넙치 대비 일부 지역을 제외하고는 $15\~25\%$나 낮아서 상당히 문제가 있었다. 사실 운동량이나 섬유질 및 생선 단백질의 섭취에 따라 증가하는 HDL-콜레스테롤이 감소한다는 사실은 연안해역의 환경개선책이 시급함을 말해준다.

Pyroptosis is an inflammatory form of programmed cell death that is linked with invading intracellular pathogens. Cardiac pyroptosis has a significant role in coronary microembolization (CME), thus causing myocardial injury. Tanshinone IIA (Tan IIA) has powerful cardioprotective effects. Hence, this study aimed to identify the effect of Tan IIA on CME and its underlying mechanism. Forty Sprague-Dawley (SD) rats were randomly grouped into sham, CME, CME + low-dose Tan IIA, and CME + high-dose Tan IIA groups. Except for the sham group, polyethylene microspheres (42 ㎛) were injected to establish the CME model. The Tan-L and Tan-H groups received intraperitoneal Tan IIA for 7 days before CME. After CME, cardiac function, myocardial histopathology, and serum myocardial injury markers were assessed. The expression of pyroptosis-associated molecules and TLR4/MyD88/NF-κB/NLRP3 cascade was evaluated by qRT-PCR, Western blotting, ELISA, and IHC. Relative to the sham group, CME group's cardiac functions were significantly reduced, with a high level of serum myocardial injury markers, and microinfarct area. Also, the levels of caspase-1 p20, GSDMD-N, IL-18, IL-1β, TLR4, MyD88, p-NF-κB p65, NLRP3, and ASC expression were increased. Relative to the CME group, the Tan-H and Tan-L groups had considerably improved cardiac functions, with a considerably low level of serum myocardial injury markers and microinfarct area. Tan IIA can reduce the levels of pyroptosis-associated mRNA and protein, which may be caused by inhibiting TLR4/MyD88/NF-κB/NLRP3 cascade. In conclusion, Tanshinone IIA can suppress cardiomyocyte pyroptosis probably through modulating the TLR4/MyD88/NF-κB/NLRP3 cascade, lowering cardiac dysfunction, and myocardial damage.

Percutaneous coronary intervention and acute coronary syndrome are both closely tied to the frequently occurring complication of coronary microembolization (CME). Resveratrol (RES) has been shown to have a substantial cardioprotective influence in a variety of cardiac diseases, though its function and potential mechanistic involvement in CME are still unclear. The forty Sprague-Dawley rats were divided into four groups randomly: CME, CME + RES (25 mg/kg), CME + RES (50 mg/kg), and sham (10 rats per group). The CME model was developed. Echocardiography, levels of myocardial injury markers in the serum, and histopathology of the myocardium were used to assess the function of the cardiac muscle. For the detection of the signaling of TLR4/MyD88/NF-κB along with the expression of pyroptosis-related molecules, ELISA, qRT-PCR, immunofluorescence, and Western blotting were used, among other techniques. The findings revealed that myocardial injury and pyroptosis occurred in the myocardium following CME, with a decreased function of cardiac, increased levels of serum myocardial injury markers, increased area of microinfarct, as well as a rise in the expression levels of pyroptosis-related molecules. In addition to this, pretreatment with resveratrol reduced the severity of myocardial injury after CME by improving cardiac dysfunction, decreasing serum myocardial injury markers, decreasing microinfarct area, and decreasing cardiomyocyte pyroptosis, primarily by blocking the signaling of TLR4/MyD88/NF-κB and also reducing the NLRP3 inflammasome activation. Resveratrol may be able to alleviate CME-induced myocardial pyroptosis and cardiac dysfunction by impeding the activation of NLRP3 inflammasome and the signaling pathway of TLR4/MyD88/NF-κB.

Objective: To explore the expression and significance of tumor specific growth factor (TSGF), carcinoembryonic antigen (CEA) and alpha fetoprotein (AFP) in cancer tissue and serum of patients with colon cancer. Materials and Methods: Radical surgery for colon cancer was performed on 43 patients with laparoscopu under conditions of general anesthesia. The Elisa method was used to detect the levels of serum TSGF, CEA and AFP before and after radical operation, and cancer tissue underwent TSGF, CEA and AFP immunohistochemistry staining after laparoscopic surgery. The decreased conditions of serum TSGF, CEA and AFP in patients with colon cancer at different levels of differentiation and clinical stagings were analyzed, and the relationships of expression rates between histological types, colon cancer morphology, lymph node metastasis and TSGF, CEA as well as AFP in cancer tissue were assessed. Results: Compared with before radical surgery, the levels of serum TSGF, CEA and AFP decreased notably in patients after operations (p<0.01). The decreased degree of TSGF and CEA was the largest in patients with poorly differentiated cancer tissue (p<0.01), while that of AFP was noted in patients with moderately differentiated cancer tissue (p<0.01). The decreased degree of TSGF and AFP was the largest in patients at phase Dukes A (p<0.01), while that of CEA in patients at phase Dukes C (p<0.01). There were no significant differences among the positive expression rates of TSGF, CEA and AFP with different histological types and colon cancer morphologies (p>0.05). The positive expression rates of TSGF and CEA in patients with lymph node metastasis were significantly higher than those without lymph node metastasis (p<0.01). Conclusions: TSGF, CEA and AFP can be used to evaluate the effect of radical operation for colon cancer, and the changed levels of different markers are associated with tumor differentiation, clinical stating and presence or absence of lymph node metastasis.

Objective : Subarachnoid hemorrhage (SAH) is a condition characterized by bleeding in the subarachnoid space, often resulting from the rupture of a cerebral aneurysm. Delayed cerebral ischemia caused by vasospasm is a significant cause of mortality and morbidity in SAH patients, and inflammatory markers such as systemic inflammatory response index (SIRI), systemic inflammatory index (SII), neutrophil-to-lymphocyte ratio (NLR), and derived NLR (dNLR) have shown potential in predicting clinical vasospasm and outcomes in SAH patients. This article aims to investigate the relationship between inflammatory markers and cerebral vasospasm after aneurysmatic SAH (aSAH) and evaluate the predictive value of various indices, including SIRI, SII, NLR, and dNLR, in predicting clinical vasospasm. Methods : A retrospective analysis was performed on a cohort of 96 patients who met the inclusion criteria out of a total of 139 patients admitted Trakya University Hospital with a confirmed diagnosis of aSAH between January 2013 and December 2021. Diagnostic procedures, neurological examinations, and laboratory tests were performed to assess the patients' condition. The Student's t-test compared age variables, while the chi-square test compared categorical variables between the non-vasospasm (NVS) and vasospasm (VS) groups. Receiver operating characteristic (ROC) curve analyses were used to evaluate the diagnostic accuracy of laboratory parameters, calculating the area under the ROC curve, cut-off values, sensitivity, and specificity. A significance level of p<0.05 was considered statistically significant. Results : The study included 96 patients divided into two groups : NVS and VS. Various laboratory parameters, such as NLR, SII, and dNLR, were measured daily for 15 days, and statistically significant differences were found in NLR on 7 days, with specific cut-off values identified for each day. SII showed a significant difference on day 9, while dNLR had significant differences on days 2, 4, and 9. Graphs depicting the values of these markers for each day are provided. Conclusion : Neuroinflammatory biomarkers, when used alongside radiology and scoring scales, can aid in predicting prognosis, determining severity and treatment decisions for aSAH, and further studies with larger patient groups are needed to gain more insights.

The effects of Malloti Cortex Water Extract (MCWE), bergenin (isolated as an active component from MCWE), and acetylbergenin (synthesized from acetylation of bergenin) on the liver fibrosis induced by bile duct ligation (BDL) in rats. We studied hydroxypro1ine (HYP) as a marker of collagen accumulation in the liver, alanine aminotransferase (s-ALT), aspartate aminotransferase (s-AST), and alkaline phosphatase (s-ALP) as serum markers of liver cell damage induced by BDL, MCWE, bergenin, and acetylbergenin decreased towards normal the accumulated levels of HYP in the liver and the elevated serum levels of s-ALT, s-AST and 5-ALP. The results indicate that MCWE, bergenin, and acetylbergenin ameliorated the liver damage induced by BDL in rats.

Background: Vaspin and Retinol binding protein-4 (RBP4) are new adipokines mainly produced by adipose tissue. Considering that medullary thyroid carcinoma (MTC) is a malignant neuroendocrine tumor, and to date the relationship between serum levels of vaspin and RBP4 with MTC has not been studied, in this matched case-control study we evaluated their possible significance to this tumor type. Materials and Methods: A total of 45 patients with MTC (21 males and 24 females) and 45 healthy persons as a control group (24 males and 21 females) were selected. The two groups were matched for age, sex and body mass index. Serum Vaspin and RBP4 levels were measured by enzyme-linked immunosorbent assay (ELISA) methods in both groups. Also, weight and height were measured and body mass index was calculated too. Results: In total, patients with MTC had significantly higher serum vaspin levels compared to the controls (0.52ng/ml vs. 0.45ng/ml, P=0.0241). However, no significant difference was found in serum RBP4 concentrations between the patients with MTC and the controls ($15.2{\pm}2.55{\mu}g/ml$ versus $15.1{\pm}3.34{\mu}g/ml$, p>0.05). Conclusions: The results of this study demonstrated that serum RBP4 levels in MTC patients are not significantly different from those found in healthy individuals and did not correlate with MTC. On the other hand, higher levels of serum vaspin are associated with an increased risk of MTC. Thus Vaspin may be a novel and promising biomarker for diagnosis or confirmation of MTC in conjunction other specific tumor markers.
