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.
Primary breast angiosarcoma (PBA) is a rare malignant tumor, and few clinical cases have been reported. In this case, the mammographic and contrast-enhanced magnetic resonance imaging of PBA were reported, and the relevant pathologic basis was also briefly introduced in order to enhance the clinicians’ understanding of the imaging manifestations of this rare disease.
Liver cancer is one of the world’s most prevalent malignancies, and is also the third leading cause of cancer death in China. Hepatitis and cirrhosis background is a major feature of liver cancer patients in China, which makes specific requirements that suits the national conditions in many aspects of prevention and control like screening diagnosis, treatment options, and prognosis follow-up. The Specifications for Diagnosis and Treatment of Primary Liver Cancer (2017 Edition), which is based on China’s practice, proposes liver cancer staging in line with China’s national conditions and forms a multi-disciplinary joint diagnosis and treatment model based on surgical treatment. Liver transplantation is included in liver cancer as one of the surgical treatments option. It also emphasizes the support of evidence-based medicine. The Specifications for Diagnosis and Treatment of Primary Liver Cancer (2017 Edition) may have laid a solid foundation for future diagnosis and treatment of liver cancer in China.
Objective To give an individualized treatment to a young woman with primary dysmenorrhea. Methods According to the basic principle and methods of evidence-base medicine, we searched The Cochrane Library (Issue 1, 2009), MEDLINE (PubMed, January 1950 to May 2009), ACP Journal Club (OVID, January 1991 to May 2007) for systematic reviews and randomized controlled trials (RCTs) to acquire the best clinical evidence on the treatment of primary dysmenorrhea. Results A total of 11 systematic reviews and 1 RCT were identified. A reasonable treatment plan was made through combining the patient’s will with her family members’. Conclusion The treatment effect on primary dysmenorrhea of the young woman is improved by an individualized treatment plan based on an evidence-based method.
ObjectiveTo compare the efficacy and safety of three different modes of blood flow blocking in hepatectomy for primary hepatocellular carcinoma.MethodsThe clinical data of 152 patients with primary hepatocellular carcinoma who underwent hepatectomy and postoperative pathology examination in our department in recent 3 years (2017–2020) were retrospectively analyzed. According to the modes of intraoperative hepatic blood flow occlusion, the patients were divided into three groups: intermittent Pringle method (IPM) group (41 cases), IPM was applied only; hemihepatic group (35 cases), hemihepatic blood flow blocking method was used only; and combined group (76 cases), combined hemihepatic blood flow blocking method and IPM. SPSS software was used to compare the differences of the three groups’ general data, intraoperative blood loss and postoperative liver function indexes. The changes of transaminase levels in the three groups were observed dynamically.ResultsBaseline data of the three groups were not statistically significant (P>0.05). There were no statistically significant differences in operative time, the number of resected liver segments, blood transfusion rate, incidence of complications, and postoperative length of stay among the three groups (all P>0.05). The intraoperative blood loss of the combined group and the IPM group were significantly less than that of the hemihepatic group (P<0.05). There was no difference in blood loss between the combined group and the IPM group (P>0.05). However, the blocking times in the combined group were significantly less than those in the IPM group (P<0.05). The transaminases in the three groups were close to the preoperative level on the fifth day after operation. Conclusions In hepatectomy of primary hepatocellular carcinoma, the three blocking modes are safe and effective. The combined application of hemihepatic blood flow blocking method and intermittent Pringle method can significantly reduce intraoperative blood loss, reduce the number of blocking, and do not aggravate the liver function injury.
