ObjectiveTo investigate the relationship of 24-hour ambulatory pulse pressure (24hPP) with left ventricular mass index (LVMI) in elderly essential hypertension patients. MethodsThe data of 110 elderly patients with essential hypertension from January to December 2012 were collected in the study. All patients received 24-hour ambulatory blood pressure monitoring and echoeardiographic examination 24hPP and LVMI were calculated according to the results of 24-hour ambulatory blood pressure monitoring and echocardiographic measurements. The patients were divided into group A [24hPP<60 mm Hg (1 mm Hg=0.133 kPa), n=70] and group B (24hPP≥60 mm Hg, n=40). ResultsThe 24-hour systolic blood pressure and 24hPP for patients in group B were significantly higher than those in group A (P<0.001). Compared with group A patients, the interventricular septal thickness, left ventricular posterior wall thickness, left ventricular mass and left ventricular mass index were significantly higher in group B (P<0.05). Pearson correlation analysis showed that 24hPP had a positive correlation with LVMI in the elderly essential hypertension patients (r=0.33, P<0.001). Multiple stepwise regression analysis showed that 24hPP was the main factor for the increase of LVMI in elderly essential hypertension patients (β=0.90, P<0.001). ConclusionThe 24hPP is positively correlated with LVMI in elderly essential hypertension patients. The 24hPP is an important risk factor for left ventricular structural damage in elderly essential hypertensive patients.
Objective To evaluate the effect of antihypertensive agents on primary aldosteronism (PA) screening test in the real world clinical practice; to explore the antihypertensive regimen and the corresponding aldosterone versus renin ratio (ARR) cut-off point of hypertension patients undergoing PA screening. Methods Hypertensive patients who underwent PA screening in the Department of Endocrinology & Metabolism of West China Hospital of Sichuan University between January 2010 and December 2020 were selected. According to the PA diagnostic criteria, patients were divided into the PA group and the essential hypertension (EH) group. The antihypertensive drugs, diastolic blood pressure, systolic blood pressure, blood electrolyte, plasma renin activity, plasma aldosterone, ARR were collected before and after the washout period; aldosterone before and after captopril test, and aldosterone before and after saline infusion test were collected. The above indicators of the two groups of patients were compared and analyzed. Results A total of 488 patients were included. Among them, there were 391 cases in the PA group and 97 cases in the EH group. There were statistically significant differences in age, systolic blood pressure, diastolic blood pressure, blood sodium, blood potassium, plasma renin activity, aldosterone, and ARR between the two groups (P<0.05). There was a significant difference in diagnostic results for PA screening between pre-eluting ARR and post-eluting ARR among patients taking 1-3 antihypertensive agents; however, there was no significant difference among patients taking 4 or more antihypertensive agents (P=0.547). Among the 488 patients included, calcium channel blocker and/or angiotensin converting enzyme inhibitors / angiotensin receptor interceptor were the most used antihypertensive regimen. ARR≥23.6(ng/dL)/[ng/(mL·h)] could be used as the cut-off point of ARR screening PA before elution. Conclusions When PA screening is performed in patients with hypertension, it can be directly screened for patients taking 4 or more antihypertensive drugs. As to patients taking 1-3 antihypertensive drugs, such as calcium channel blocker and/or angiotensin converting enzyme inhibitors / angiotensin receptor interceptor, ARR≥23.6 (ng/dL)/[ng/(mL·h)] can be selected as the cut-off value.
【Abstract】Objective To investigate the imaging features of malignant invasion of major intrahepatic ductal structures (the portal and hepatic venous vasculature, the bilie duct) by primary hepatocellular carcinoma (HCC) using multidetector-row spiral CT (MDCT). Methods We retrospectively analyzed 68 documented HCC patients with tumorous invasion of the major intrahepatic ductal structures who had undergone contrast-enhanced dual-phase MDCT scanning of the upper abdomen.The morphological changes of the portal and hepatic venous vasculature, the bile duct, and the liver parenchyma at both the hepatic arterial phase and portal venous phase images were carefully observed and recorded. Results Among the 68 patients, 47 patients had malignant invasion of the intrahepatic portal venous vessels with secondary tumor thrombus formation; 12 patients had tumor involvement of the hepatic veins and intraheptic segment of the inferior vena cava; Tumor invasion of the bile duct was seen in 9 patents. The direct CT signs of tumor invasion of intrahepatic venous vessels included: ①dilatation or enlargement of the involved vein with intraluminal softtissue “filling defect”； ②enhancement of the tumor thrombus at hepatic arterial phase, the so-called “venous arterialization” phenomenon. The indirect CT signs included: ①arterial-venous shunt, ②early and heterogeneous enhancement of the hepatic parenchyma adjacent to HCC focus, ③cavernous transformation of the portal vein. The CT signs suggesting tumor invasion of the bile duct included: ①dilation of the bile ducts near or proximal to HCC lesion, ②soft-tissue nodule or mass inside the bile ducts. Conclusion Invasion of major intrahepatic ductal structures by HCC will present corresponding CT imaging features. Contrast-enhanced MDCT dualphase scanning combined with appropriate image postprocessing techniques can better evaluate the malignant invasion of major intrahepatic ductal structures.
In 2022, there were 367.7 thousands new cases and 316.5 thousands deaths of primary liver cancer in China. Radiofrequency ablation (RFA) is one of the radical treatments for liver cancer. It has the characteristics of definite curative effect, minimal invasion and low cost. In patients with early liver cancer, the curative effect is similar to surgical resection. The concept and practice of precision surgery provide new ideas for improving the efficacy of RFA. Based on the RFA treatment experience of more than ten thousand cases, the author’s team has carried out research on the precise ablation treatment of primary liver cancer. Now, the author will combine the existing literature and our team’s experience to discuss the application and prospect of the precise surgery concept in RFA treatment.
Objective To study the association and the effect of the expression of p16 and p53 protein on the occurence and development of gallbladder carcinoma. Methods The expression of p16 and p53 protein were detected in 40 cases of gallbladder carcinoma with immunohistochemical method. Results The expressions of p16 and p53 protein were closely correlated to the tumor pathological grade, lymph mode metastasis and prognosis. p16 protein was correlated to the Nevin classifications. Conclusion The results indicate that the low expression rate of p16 protein occurred in the advanced stage of gallbladder carcinoma. The expression of p16 and p53 protein are helpful in judging the malignant degree and prognosis of primary gallbladder cancer.
ObjectiveTo discuss the effects of diabetes mellitus (DM) on gastrointestinal hormone changes before and after hepatocellular carcinoma (HCC) operation. MethodsThe clinical data of 143 patients with HCC treated in this hospital from April 2007 to Febuary 2010 were analyzed, which 43 patients with DM (DM group) and 100 patients without DM (NDM group). Gastrin (GAS) and motilin (MTL) levels were measured on day 3 before operation and on day 1, 2, and 7 after operation. Results① The blood MTL levels decreased and GAS levels increased on day 1, 2, and 7 after operation as compared with the levels before operation (all Plt;0.05). ② The blood MTL level and GAS level before operation in the DM group was higher than that in the NDM group (Plt;0.05), MTL level decreased while GAS level increased more significantly on day 1, 2, and 7 after operation (Plt;0.05). ③ The first anus exhausting time of patients with NDM was much earlier than that with DM (Plt;0.05). ④ The first anus exhausting time with DM over 10 years and fasting plasma glucose over 10 mmo1/L was obviously extended (Plt;0.05). ConclusionDM affectes GAS and MTL level changes after HCC operation, recovery of gastrointestinal function would be delayed if patients with long course of DM and poor control of plasma glucose.
