Efficacy of peginterferon alfa-2a combined with entecavir in sequential treatment of chronic hepatitis B / 中国基层医药

Objective:To investigate the efficacy of peginterferon alfa-2a (Peg-IFNα-2a) combined with entecavir in sequential treatment of chronic hepatitis B.Methods:A total of 106 patients with chronic hepatitis B who received treatment in Affiliated Hangzhou Xixi Hospital of Zhejiang University School of Medicine from January 2020 to February 2022 were included in this study. They were divided into a control group (entecavir treatment, n = 53) and a study group (sequential therapy with Peg-IFNα-2a followed by entecavir, n = 53). Liver function indicators, liver fibrosis indicators, clinical treatment efficacy, and incidence of adverse reactions were compared between the two groups before and after treatment. Results:After treatment, total bilirubin, alanine aminotransferase and aspartate transaminase in the control and study groups were (94.79 ± 8.71) μmol/L and (67.67 ± 9.19) μmol/L, (256.93 ± 44.07) U/L and (186.56 ± 48.37) U/L, (256.47 ± 43.73) U/L and (200.69 ± 41.34) U/L, and they were (140.05 ± 26.15) μmol/L and (141.32 ± 25.35) μmol/L, (433.66 ± 77.16) U/L and (429.77 ± 73.73) U/L, (352.34 ± 65.19) U/L and (354.05 ± 66.13) U/L before the treatment. After treatment, these indexes in each group were decreased compared with before treatment ( t = 19.19, -12.13, -28.85, -20.96, -19.27, -12.03, all P < 0.05). After treatment, these indexes in the study group were significantly lower than those in the control group ( t = -6.49, -7.30, -6.74, all P < 0.001). After treatment, the levels of hyaluronic acid, laminin, type III procollagen peptide, and type IV collagen in the control and study groups were (124.91 ± 22.99) μg/L and (101.29 ± 22.67) μg/L, (132.71 ± 25.37) μg/L and (110.56 ± 25.49) μg/L, (116.93 ± 20.29) μg/L and (93.14 ± 20.39) μg/L, (63.14 ± 12.19) μg/L and (50.81 ± 11.63) μg/L, and they were (175.73 ± 48.56) μg/L and (177.61 ± 48.51) μg/L, (163.43 ± 41.52) μg/L and (165.57 ± 41.59) μg/L, (139.71 ± 31.75) μg/L and (141.72 ± 31.78) μg/L, (106.97 ± 32.24) μg/L and (104.02 ± 34.12) μg/L before treatment. After treatment, the levels of these indexes in each group were significantly decreased compared with before treatment ( t = -13.04, -8.68, -10.43, -5.82, -13.35, -6.26, -13.02, -10.72, all P < 0.05). After treatment, the levels of these indexes in the study group were significantly lower than those in the control group ( t = -5.32, -4.48, -6.02, -5.32, all P < 0.001). The total response rate in the study group was 88.68% (47/53), which was significantly higher than 62.26% (33/53) in the control group ( χ2 = 9.98, P < 0.05). The HBsAg conversion rate in the study group was 33.96% (18/53), which was significantly higher than 1.32% (6/53) in the control group ( χ2 = 7.75, P < 0.05). There was no statistically significant difference in the incidence of adverse reactions between the study and control groups [26.42% (14/53) vs. 30.19% (16/53), χ2 = 0.81, P > 0.05]. Conclusion:Sequential therapy with Peg-IFNα-2a followed by entecavir can effectively improve liver function,reduce liver fibrosis , improve clinical treatment efficacy, and will not increase adverse reactions.

Assessment of mitral annulus (p3 segment) asymmetric deformity in myocardial infarction with ischemic regurgitation by real time three-dimensional echocardiography.

OBJECTIVE: The three-dimensional (3D) saddle shape of the mitral annulus (MA) is well characterized in humans, but segmental MA deformity and regurgitation suffered after the ischemic damage of myocardial infarction (MI) is poorly understood. In this study, such changes were assessed in patients with ischemic mitral regurgitation (IMR) post-MI, using our computerized 3D echo technique. METHODS: A patient cohort (n = 72) with IMR due to inferior or anterior MI and normal controls (n = 20) were enrolled for 3D MA echo studies. Sequential coordinates of MA were manually measured from each of 18 radial planes, cropped in midsystole, to generate 3D MA images. In addition, six segmental (A1, A2, A3, P1, P2, P3) parameters of MA and global features, such as circumference, area, and height, were calculated. RESULTS: All six segments of MA were significantly dilated in the IMR group compared with corresponding segments of normal controls. Although there were no significant intragroup differences in A1, A2, and A3 segments, a greater degree of P3 segmental MA deformity was observed only in patients following inferior MI. CONCLUSION: The MA dilatation observed in patients with IMR after MI was more pronounced in patients with anterior versus inferior MI. However, P3 segmental dilatation of MA was significantly greater in patients after inferior IM with significant IMR, corresponding with more severe asymmetric MA deformity.

Expression of RUNX3 mRNA in primary liver cancer and its clinical significance / 中华肝胆外科杂志

Objective To study the expression of RUNX3 mRNA in primary liver cancer (PHC) tissue and its surrounding normal tissue,and its clinical significance.MethodsReverse transcription polymerase chain reaction (RT-PCR) was performed to detect the expression of RUNX3 mRNA in tumor and peritumor tissues in 51 patients with PHC.The relationship between RUNX3 mRNA expression and some clinical pathological parameters was analyzed.ResultsThe relative expression values of RUNX3 mRNA in the tumor tissue and the surrounding normal tissue were 0.4509±0.0963 and 0.9147± 0.0222,respectively.The difference was significant (t=33.6087,P＜0.001).The RUNX3 mRNA expression in tumor tissue correlated with some clinical pathological parameters including low tumor differentiation,positive cancer embolus and intrahepatic invasion and metastasis.The RUNX3 mRNA expression was not correlated with other clinicopathological parameters including gender,cancer diameter,cancer location,hemorrhage and necrosis of cancer,and histotype.ConclusionRUNX3 may be a new tumor suppressor gene for PHC.

Clinical analysis of 165 cases of pancreaticoduodenectomy / 中华胰腺病杂志

Objective To investigate the evolution of pancreaticoduodenectomy and its significance in different time periods. Methods The clinical data of 165 patients from 1988 to 2008 in the department of general surgery, Zhangzhou Municipal Hospital with pancreaticoduodenectomy were retrospectively analyzed.Among 165 cases, simple pancreatoduodenectomy (PD) were performed in 138 cases, pylorus preserving pancreatoduodenectomy (PPPD) were performed in 14 cases, and extended pancreaticoduodenectomy were performed in 13 cases. The methods of pancreato-enteric reconstruction in pancreaticoduodenectomy included 68 cases with binding pancreaticojejunostomy (Peng's type Ⅰ ); 61 cases with pancreaticogastrostomy; 30 cases with traditional pancreaticojejunostomy; and 6 cases with duct-to-mucous pancreaticojejunostomy.Results From 1988 to 1998 (the first 10 years), 50 patients underwent pancreaticoduodenectomy, including 42 cases of PD and 8 cases of PPPD, and no case of extended pancreaticoduodenectomy. The mean amount of blood loss was (620 ± 180)ml, mean amount of blood transfusion was (530 ± 120)ml, the mean operation time was (6.5 ±3.5)h. Anastomotic fistula occurred in 7 cases, the incidence of anastomotic fistula was 14.0%(7/50); and 2 cases died during perioperative period with a mortality rate of 4.0% (2/50). From 1999 to 2008 (the latter 10 years), 115 patients underwent pancreaticoduodenectomy, including 96 cases of PD, 6 cases of PPPD, and 13 cases of extended PD. The mean amount of blood loss was (360 ± 110)ml, mean amount of blood transfusion was (400 ± 6 ) ml, the mean operation time was ( 3.0 ± 2.5 ) h, Anastomotic fistula occurred in 4 cases with an incidence of 3.5% ( 4/115 ); and one case during perioperative period with a mortality rate of 0.61%. The postoperative follow up time was ranging from 6 months to 5 years in 109 patients, the 1, 3,5 year survival rate was 87.2%, 54.1% and 39.5%. Conclusions In the latter 10 years, the amount of blood loss, the operation time, the mortality, and the incidence of pancreatic fistula have decreased significantly compared to the first 10 years.
