ABSTRACT

Objective:To investigate the diagnostic value of Chinese-thyroid imaging reporting and data system (C-TIRADS) combined with shear wave elastography (SWE) in thyroid microcarcinoma.Methods:The clinical data of 270 patients (367 nodules) who underwent thyroid ultrasound examination and confirmed by pathology from January 2019 to June 2021 in the Affiliated Hospital of Jining Medical University were analyzed retrospectively. All patients were assisted by SWE in preoperative ultrasound examination to measure the maximum elastic modulus (E max), the average elastic modulus (E mean) and the minimum elastic modulus (E min). The receiver operating characteristic (ROC) curve was drawn to get the optimal threshold of SWE according to the pathological results. The diagnostic value of C-TIRADS, SWE and their combined in different diameters thyroid micronodules was analyzed. Results:Among 367 thyroid nodules, 119 nodules were benign and 248 nodules were malignant. The area under the curve (AUC) of E max in diagnosing TMC was significantly larger than that of E mean and E min (0.883 vs. 0.822 and 0.706), and there was statistical difference ( P<0.05); the best cut-off value of E max was 29.5 kPa. The ROC curve analysis results showed that the AUC of C-TIRADS combined with SWE in diagnosis of TMC was significantly larger than that of C-TIRADS and SWE alone (0.884 vs. 0.800 and 0.853), and there was statistical difference ( P<0.05); the sensitivity, accuracy and negative predictive value of C-TIRADS combined with SWE in diagnosis of TMC were significantly higher than those of C-TIRADS alone (90.32% vs. 80.24%, 89.10% vs. 80.11% and 81.10% vs. 65.97%), and there were statistical differences ( P<0.05). Thyroid nodules were divided into ≤0.5 cm nodules (56 nodules) and 0.5 to 1.0 cm nodules (311 nodules) according to the maximum diameter, the sensitivity and accuracy of C-TIRADS combined with SWE in diagnosing TMC in 0.5 to 1.0 cm nodules were significantly higher than those in ≤0.5 cm nodules: 91.82% (202/220) vs. 78.57% (22/28) and 90.68% (282/311) vs. 80.36% (45/56), and there were statistical differences ( χ2 = 4.99 and 5.20, P<0.05), but there was no statistical difference in specificity between 2 groups ( P<0.05). Conclusions:C-TIRADS combined with SWE can further improve the diagnostic value of TMC, which is worth popularizing and applying in clinic.

ABSTRACT

Objective@#To investigate the occurrence of lymph node micrometastasis in pancreatic head carcinoma and analyze its effect on the prognosis of patients.@*Methods@#The lymph nodes in 40 patients who received pancreatoduodenectomy with regional lymphadenectomy were dissected by surgical magnification microscopy. The expression of cytokeration(AE1/E3) were detected by immunohistochemical staining in the pathologically negative lymph nodes. The frequency of lymph nodes metastases and micrometastases, as well as the relationship between metastasis and prognosis were analyzed.@*Results@#1 550 lymph nodes were dissected from 40 patients. Lymph node metastases was pathologically detected in 27 patients (67.5%) and in 199 lymph nodes(12.8%). No.13(24.1%, 68/282), No.14(18.1%, 58/321), No.12(12.7%, 31/245), No.16(12.3%, 30/243) and No.17(11.4%, 12/105) lymph nodes groups had higher frequency of metastases. Lymph node micrometastases was immunohistochemically detected in 6 patients and 130 lymph nodes. No.14(16.5%, 53/321), No.13(15.2%, 43/282), No.16(6.2%, 15/243), No.12(4.9%, 12/245) and No.8(5.0%, 7/141) lymph nodes groups had higher frequency of micrometastases. The total ratio of patients with postive lymph nodes invasion and the ratio of positive lymph nodes invasion were 82.5% and 21.2%. 11 patients survived more than one year. 29 patients died of recurrence or metastasis within 8~11 months after surgery. The 1-year survival rate was 27.5%. 1-year survival rate was 14.9% in HE (+ ) patients, and 33.3% in HE (-) AE1/E3 (+ ) patients (P=0.632). AE1/E3 (-) HE (-) patients had a 1-years survival rate of 71.4%, which was statistically higher than that in HE (+ ) group patients (P=0.010).@*Conclusions@#AE1/E3 combined with pathological examination can significantly improve the detection rate of lymph nodes micrometastasis in pancreatic head carcinoma patients. Micrometastasis is commonly found in No 13, 14, 12, 16, 8 lymph nodes groups. Lymph nodes micrometastasis had a significant effect on the prognosis of patients. Special attention should be payed to No 13, 14, 16, 12, 17 lymph nodes groups during radical duodenopancreatectomy.

ABSTRACT

BACKGROUND/AIMS: Gastric hypersensitivity contributes to abdominal pain in patients with functional dyspepsia. Recent studies showed that hormones induced by stress are correlated with visceral hypersensitivity. However, the precise mechanisms underlying gastric hypersensitivity remain largely unknown. The aim of the present study was designed to investigate the roles of corticosterone (CORT) on excitability of dorsal root ganglion (DRG) neurons innervating the stomach. METHODS: DRG neurons innervating the stomach were labeled by DiI injection into the stomach wall. Patch clamp recordings were employed to examine neural excitability and voltage-gated sodium channel currents. Electromyograph technique was used to determine the responses of neck muscles to gastric distension. RESULTS: Incubation of acutely isolated DRG neurons with CORT significantly depolarized action potential threshold and enhanced the number of action potentials induced by current stimulation of the neuron. Under voltage-clamp mode, incubation of CORT enhanced voltage-gated sodium current density of the recorded neurons. Pre-incubation of GF109203X, an inhibitor of protein kinase C, blocked the CORT-induced hyperexcitability and potentiation of sodium currents. However, pre-incubation of H-89, an inhibitor of protein kinase A, did not alter the sodium current density. More importantly, intraperitoneal injection of CORT produced gastric hypersensitivity of healthy rats, which was blocked by pre-administration of GF109203X but not H-89. CONCLUSIONS: Our data strongly suggest that CORT rapidly enhanced neuronal excitability and sodium channel functions, which is most likely mediated by protein kinase C but not protein kinase A signaling pathway in DRG neurons innervating the stomach, thus underlying the gastric hypersensitivity induced by CORT injection.

ABSTRACT

Silibinin, from milk thistle (Silybum marianum), is a flavonolignan with anti-oxidative and anti-inflammatory properties. It has been therapeutically used for the treatment of hepatic diseases in China, Germany and Japan. Recently, increasing evidences prove that silibinin is also a potent antitumor agent, and the major anti-tumor mechanism for silibinin is the prominent inhibition of the activities of receptor tyrosine kinases (RTKs) and their downstream signal molecules in a variety of tumor cell lines, such as epidermal growth factor receptor 1 (EGFR) and insulin-like growth factor 1 receptor (IGF-1R) signaling pathways. Meanwhile, the evidences that silibinin selectively scavenges hydroxyl free radical (*OH) and specifically inhibits the action of nuclear factor kappaB (NF-kappaB) provide more complicated explanations for its antioxidant and anti-inflammatory effects. Some new findings such as that silibinin attenuating the cognitive deficits induced by amyloid beta protein (Abeta) peptide through its antioxidative and anti-inflammatory properties is valuable to broad the medical prospect of silibinin. In this review, we discuss the molecular pharmacological mechanisms of silibinin, focusing on its inhibition of tyrosine kinases, actions of antioxidation, free radical scavenging, immunoregulation and anti-inflammation.
