Background/Aims: Extended hepatectomy combined with caudate lobe resection has been approved for the radical resection of hilar cholangiocarcinoma. There was a lack of credible research on the clinical value of caudate lobectomy (CL) for intrahepatic cholangiocarcinoma involving the hepatic hilus when combined with hepatectomy. We aimed to compare the short-term and long-term outcomes of the combined procedure with those of only CL for curative resection of intrahepatic cholangiocarcinoma involving the hepatic hilus. Methods: This single-center retrospective cohort study of patients with hilar cholangiocarcinoma was conducted from January 2007 to December 2021. Patients who underwent radical resection were enrolled in this study. The short-term and long-term clinical outcomes of the groups were compared before and after propensity score matching (PSM). Results: A total of 282 patients were included. There were no statistically significant differences in perioperative clinical outcomes between the CL group and the non-CL group before and after PSM. Compared to patients in the non-CL group, patients in the CL group had significantly longer overall survival before and after PSM (p=0.007 before PSM, p=0.033 after PSM). Moreover, compared to the non-CL group, the CL group had longer disease-free survival before and after PSM (p<0.001 before PSM, p=0.019 after PSM). Conclusions The postoperative complications of the CL group were comparable to those of the non-CL group. CL improved the long-term survival of patients with intrahepatic cholangiocarcinoma involving the hepatic hilus when combined with hepatectomy. Therefore, hepatectomy combined with caudate lobe resection should be performed for patients with hilar cholangiocarcinoma.

  Objective  To explore the mechanism of Wnt5a on keratinocyte involved in the peripheral sensitization of complex regional pain syndrome type-Ⅰ (CRPS-Ⅰ) by regulating the expression of MMP9, and search for potential therapeutic strategies.  Methods  Cultured HaCaT cells were treated with oxygen glucose deprivation/re-oxygenation (OGD/R). The early stage of mitochondrial damage and membrane potential changes after OGD/R and the effects of Box5 (Wnt5a inhibitor) at different concentrations (20 μmol/L, 40 μmol/L) on MMP9 were explored. Adult male Sprague-Dawley rats were divided into Control group(n=8), CPIP group (n=8), Box5 (20) group (n=8) and Box5 (40) group (n=8). The rat chronic post-ischemia pain (CPIP) model was established to mimic the pathophysiological process of CRPS-Ⅰ. Box5 (20) group and Box5 (40) group were treated with intraplantar injection of 20 μmol/L and 40 μmol/L Box5 100 μL, respectively. The changes of mechanical withdrawal threshold and thermal withdrawal latency were measured within two weeks, and the skin inflammatory infiltration and keratosis were observed by HE staining. The expression of MMP9 was observed by immunofluorescence, and the levels of IL-1β and TNF-α in dorsal root ganglion of different groups were detected by ELISA.  Results  Vitro experiment: After OGD/R treatment, the mitochondrial atrophy was observed in OGD/R group under transmission electron microscope and the average fluorescence intensity of MMP9 was found to increase significantly (P<0.001). Compared with Control group, the mitochondrial membrane potential in OGD/R group decreased significantly by JC-1 detection (P=0.027). Compared with OGD/R group, only Box5 (40) group had a statistically significant increase in mitochondrial membrane potential (P=0.046). Animal experiment: Behavioral tests showed that the mechanical pain threshold and thermal pain threshold of CPIP group were significantly decreased at each time point (D1, D2, D4, D10, D14) (all P<0.05). HE staining indicated that there was a large-scale infiltration of inflammatory cell in the dermis and excessive keratosis in the epidermis, and the thickness of stratum granulosum and stratum spinosum increased significantly (P < 0.001). Immunofluorescence analysis showed that the expression of MMP9 in CPIP group was significantly increased (P<0.001). Compared with CPIP group, the fluorescence intensity of MMP9 in Box5 (20) group (P=0.002) and Box5 (40) group (P<0.001) were significantly decreased. ELISA results showed that the concentrations of IL-1β (P=0.048) and TNF-α (P=0.002) in CPIP group were significantly increased. Compared with CPIP group, the concentrations of IL-1β (P=0.047) and TNF-α (P=0.047) were significantly decreased in Box5 (40) group.  Conclusions  Peripheral ischemia reperfusion injury leads to overexpression of MMP9 on keratinocytes, resulting in CRPS-Ⅰ peripheral sensitization. Targeted inhibition of Wnt5a/MMP9 pathway can reverse pain behavior in rat model of CPIP, thus providing a strategy for clinical treatment of chronic pain.

  Objective  To elucidate whether coffee consumption and caffeine intake was associated with various subtypes of pain based on extensive data from publicly accessible databases.  Methods  The information was extracted from three cycles of the American National Health and Nutrition Examination Survey (1999—2000, 2001—2002, 2003—2004), encompassing data on coffee consumption, pain information, and 11 covariates (including age, gender, race, etc.). Multinomial logistic regression in three models were utilized for analysis.  Results  A total of 13 428 participants were included in this study, with a mean age of (49.79±19.06)years and a male-to-female ratio of 0.9∶1. Daily coffee intake: non-drinker 7794(58.0%), > 0-2 cups 2077(15.5%), > 2 cups 3557(26.5%); daily caffeine intake: without intake 7794(58.0%), > 0-200 mg 3152(23.5%), > 200 mg 2482(18.5%); pain situation: no pain or pain duration < 24 h 10 202(76.0%), acute pain 910(6.8%), subacute pain 369(2.7%), chronic pain 1947(14.5%). After weighting, 13 428 participants were expected to represent 190 million(190 709 157) U.S. citizens aged ≥20 years, and the overall prevalence of acute, subacute, and chronic pain in the U.S. population during that period was estimated to be 8%, 3%, and 16%, respectively. Without adjusting for covariates, individuals who consumed more than 2 cups of coffee or 200 mg of caffeine per day exhibited an elevated risk of chronic pain compared to non-coffee/caffeine drinkers, with an odds ratio of 1.354(95% CI: 1.187-1.544) and 1.372(95% CI: 1.185-1.587), respectively. After adjusting for partial covariates including age, sex, and race, individuals who consumed more than 2 cups of coffee or more than 200 mg of caffeine per day still demonstrated an increased risk of chronic pain with an odds ratio of 1.243(95% CI: 1.083-1.427) and 1.249 (95% CI: 1.072-1.456), respectively. However, after all covariates were adjusted, there was no significant association between coffee/caffeine consumption and chronic pain. Furthermore, the number of cups of coffee consumed or caffeine intake showed no significant correlation with acute and subacute pain.  Conclusions  Compared with nondrinkers, heavy daily coffee drinkers may be more likely to have chronic pain, but it is affected by multiple factors. Basic research and prospective clinical studies are needed to further determine the causality in this association.
