Splanchnic nerve block (SNB) is performed to relieve intractable upper abdominal pain caused by carcinoma of the upper G-I tract. Not all patients achieve satisfactory pain relief; therefore, a second or third nerve block trial may need to be performed. In this study, an attempt was made to analyze the possible factors which might affect the result of repeated SNB in 42 the patients among 264 patients who received SNB at Severance Hospital during the period from January 1985 to December 1989. The results are as follows: 1) Among the 42 patients, including 30 males and 12 females, the fifties and forties were the major age groups. 2) Among the underlying diseases, stomach cancer was the most common (18 cases) and pancreatic cancer was next (14 cases). 3) The main locations of pain were the upper abdomen, epigastrium and entire abdomen in decreasing order. 4) Among the thirty-nine cases of first SNB combined with ascites, 13 cases received a repeat block, 81.0% of whom had had metastatic lesion. 5) There were 54.2% who had had single or combined treatment, operation, chemotherapy or radiotherapy before SNB. 6) Twently seven cases (64.3%) had received opioid medication for pain control. 7) In the 75% alcohol group, 11.7% of patients required a second block, and in the pure and 50% alcohol group, 9.6% of patients required a second block within two weeks of the first block. Three cases in both of these repeated block groups required a third block; representing 3.9%, of the 75% alcohol group and 1.6% of the pure and 50% alcohol group. 8) The volume of alcohol used was more than 16 ml bilaterally in both cases. 9) The points of the inserted needle were positioned in the upper and anterolateral part of the $L_1$ vertebra on both sides on the anteroposterior roentgenogram. The contrast media was spread upward along the anterior margin of the vertebral body and posteriorly in repeat block. The frequency of repeat block was higher in cases with ascites or metastasis. The instance of repeat block within 2 weeks of the first block was lower in the pure and 50% alcohol group than in the 75% alcohol group. Thus, alcohol concentration and patient status may be considered factors which influence the result of repeated SNB. We suggest early application of SNB in upper abdominal cancer patients.

Background: Malignant mesothelioma (MM) is an aggressive tumor of mesothelial surfaces. Previous studies have observed an association between ABO blood groups and risk of certain malignancies, including pancreatic and gastric cancer; however, no information on any association with MM risk is available. The aim of this study was to investigate possible associations amoong MM clinicopathological features and ABO blood groups and Rh factor. Materials and Methods: In 252 patients with MM, the ABO blood group and Rh factor were examined and compared with the control group of 3,022,883 healthy volunteer blood donors of Turkish Red Crescent between 2004 and 2011. The relationship of blood groups with various clinicopathological features were also evaluated in the patient group. Results: The median age was 55 (range: 27-86) and 61.5% of patients were male. While 82.8% of patients had a history of exposure to asbestos, 60.7% of patients had a smoking history. Epithelioid (65.1%) was the most common histology and 18.7% of patients had mixed histology. Overall, the ABO blood group distribution of the 252 patients with MM was comparable with the general population. The median overall survival (OS) was 14 months (95% confidence interval, 11.3-16.6 months). The median OS for A, B, AB, and O were 11, 15, 16, and 15 months respectively (p=0.396). First line chemotherapy was administered to 118 patients. The median OS of patients on pemetrexed or gemcitabine was longer than patient who was not administered chemotherapy [17 months (95%CI, 11.7-22.2) vs. 9 months (95%CI, 6.9-11.0); p<0.001]. Conclusions: The results of this study suggest that patients with MM can benefit from treatment with pemetrexed or gemcitabine in combination with cisplatin. We did not observe a statistically significant association between ABO blood group and risk of MM.

"Ginseng (Panax ginseng C.A. Meyer) has been a popular herbal remedy used in eastern Asian cultures for thousands of years, and a number of health claims are made for it. Modern therapeutic claims for ginseng refer to vitality, immune function, cancer, cardiovascular diseases, diabetes and sexual function. These claims are mostly based on uncontrolled or non-randomized studies. Among modern therapeutic claims, however, therapeutic effects for diabetes can reasonably be accepted. Following experiment was done recently in our lab: this study was designed to compare the antidiabetic activities between Ginseng Radix Alba (GRA), Ginseng Radix Rubra (GRR) and Panax Quinquefoli Radix (PQR) in multiple low dose (MLD) streptozotocin (STZ) (20mg/kg i.p injection for 5 days) induced diabetic rats. In the glucose tolerance test, 500mg/kg of each ginseng ethanol extract was admoinistered intraperitoneally 30min before glucose challenge. While GRA failed to lower blood glucose level, GRR and PQR both significantly prevented the hyperglycemia when compared with the control group. In the MLD STZ-induced diabetic rats, 300 mg/kg of each ginseng ethanol extract was administered intraperitoneally for 2 weeks. Plasma glucose and insulin levels were markedly improved in all treatment groups. While GRR showed the highest antidiabetic activity, and GRA and PQR revealed somewhat equipotent antidiabetic activities, but less than that in GRR-treated group as for as blood parameters and diabetic symptoms such as polydipsia are concerned. Blood glucose levels were closely associated with plasma insulin levels, and this result may suggest that ginseng ethanol extracts showed the activity to enhance insulin secretion as well as preventing destruction of pancreatic islet cells. To elucidate the relationship between antidiabetic activity and ginsenoside profiles, seven major ginsenoside were quantified by HPLC. We figured out the fact that protopanaxatriol (PPT) : proptopanaxadiol (PPD) ratio might play an important role in its hypoglycemia effects."

Xanthogranulomatous inflammation is a rare benign condition involving various organs. However, its pancreas involvement is very rare. To the best of our knowledge, only 17 cases have been described in the literature. Interestingly, all reported 17 cases due to various causes underwent surgical resection. Here, we present a case of xanthogranulomatous pancreatitis in a 63-year-old man. He presented with epigastric pain and solid mass mimicking ductal adenocarcinoma in the body and tail of pancreas on magnetic resonance imaging. The patient was diagnosed as xanthogranulomatous pancreatitis via endoscopic ultrasound-guided fine needle aspiration. After that, he was followed up and monitored without any surgical treatment. Here, we show imaging findings and serial image changes of xanthogranulomatous pancreatitis for this case.

Head and neck squamous cell carcinoma (HNSCC) is the most frequent type of head and neck cancer that usually arises from the mucosal surfaces of several organs including nasal cavity, paranasal sinuses, oral cavity, tongue, pharynx, and larynx. The Wnt signaling pathway is a crucial mechanism for cellular maintenance and development. It regulates cell cycle progression, apoptosis, proliferation, migration, and differentiation. Dysregulation of this pathway correlates with oncogenesis in various tissues including breast, colon, pancreatic as well as head and neck cancers. The present study aims to assess the gene alterations in the Wnt family of genes so as to derive an association with HNSCC. Computational approaches have been utilized for the identification of gene alterations in the Wnt family of genes. Several databases such as cBioportal, STRING, and UALCAN were used for the purpose. The frequency of alteration was high in case of Wnt family member 11 (5%). Gene amplification, deep deletions, missense and truncating mutations were observed in HNSCC patients. There was a marked difference in the gene expression profile of WNT11 between grades as well as normal samples. The survival probability measured using the Kaplan-Meier curve also presented with a significant difference among male and female subjects experiencing a low/medium level expression. The female patients showed less survival probability when compared to the male subjects. This provides the prognostic significance of the WNT11 gene in HNSCC. Taken together, the present study provides clues on the possible association of WNT11 gene alterations with HNSCC, which has to be further validated using experimental approaches.

Objectives : Smilacis Glabrae Rhizoma (SGR) has been used in traditional medicine for treating diseases related to inflammation and cancer. However, the protective effect of SGR has not been reported in the study of acute pancreatitis (AP). Therefore, this study was performed to evaluate the protective effects of SGR water extract on cerulein-induced AP. Methods : AP was induced by intraperitoneal injection of supramaximal concentrations of stable cholecystokinin analogue cerulein ($50{\mu}g/kg$) 6 times at intervals of one hour in mice. SGR water extract (0.01, 0.05, or 0.1 g/kg) was administrated intraperitoneally 1 h prior to the first injection of cerulein. The mice were sacrificed at 6 h after the final injection of cerulein. Pancreas and lung were rapidly removed for histochemical examination and myeloperoxidase (MPO) assay. In addition, polymerase chain reaction (PCR) was performed to examine mRNA levels of proinflammatory cytokines such as interleukin(IL)-6, $IL-1{\beta}$ and Tumor necrosis $factor(TNF)-{\alpha}$. Results : Administration of SGR water extract significantly inhibited pancreatic weight to body weight ratio. In addition, SGR treatment inhibited the histological damages and increase of MPO activity in both pancreas and lung during AP. Also, mRNA levels of IL-6 but not $IL-1{\beta}$and $TNF-{\alpha}$ were inhibited by SGR water extract against AP. Conclusion : Our results revealed that pre-treatment of SGR water extract reduces the severity of cerulein-induced AP. Therefore, this study suggest that SGR could be used as a drug or agent to prevent AP.

Despite improvements in operative techniques and perioperative care, post-hepatectomy liver failure (PHLF) remains the most serious cause of morbidity and mortality after surgery, and several risk factors have been identified to predict PHLF. Although volumetric assessment using imaging contributes to surgical simulation by estimating the function of future liver remnants in predicting PHLF, liver function is assumed to be homogeneous throughout the liver. The combination of volumetric and functional analyses may be more useful for an accurate evaluation of liver function and prediction of PHLF than only volumetric analysis. Gadoxetic acid is a hepatocyte-specific magnetic resonance (MR) contrast agent that is taken up by hepatocytes via the OATP1 transporter after intravenous administration. Gadoxetic acid-enhanced MR imaging (MRI) offers information regarding both global and regional functions, leading to a more precise evaluation even in cases with heterogeneous liver function. Various indices, including signal intensity-based methods and MR relaxometry, have been proposed for the estimation of liver function and prediction of PHLF using gadoxetic acid-enhanced MRI. Recent developments in MR techniques, including high-resolution hepatobiliary phase images using deep learning image reconstruction and whole-liver T1 map acquisition, have enabled a more detailed and accurate estimation of liver function in gadoxetic acid-enhanced MRI.
