Abstract: Objective To construct a mouse model of Schistosoma japonicum liver disease induced by direct injection of Schistosoma japonicum eggs through the portal vein and evaluate its effectiveness, in order to provide a new animal model for schistosomiasis liver disease research. Methods Fifteen 8-week-old C57BL/6 male mice were randomly divided into control group and egg injection group, with 5 in the control group and 10 in the egg injection group. On day -14, 5 000 live eggs were injected into the abdominal cavity of mice, and on day 0, the mice were anesthetized and the abdominal cavity was opened. 5 000 live eggs were injected through the portal vein, and the control group was injected with equal volume of phosphate buffer (PBS). 5 mice in the egg group were killed on day 10 and 30, respectively. The control group mice were killed on day 10, and their serum and liver tissue were collected. Hematoxylin eosin staining (HE) and Masson staining were performed, and alanine aminotransferase (ALT), aspartate aminotransferase (AST), and liver hydroxyproline (HYP) content were detected using a microplate spectrophotometer. Liver fibrosis-related genes, Th1 and Th2 type immune response-related genes were analyzed by real-time fluorescence quantitative PCR (qPCR). Liver injury, egg granuloma and fibrosis, and adaptive immune response were detected to evaluate the effect of portal vein injection of eggs while inducing mouse model of schistosomiasis liver disease. Results The results showed that significant egg granulomas appeared in the liver of mice after injection of eggs into the portal vein for 10 and 30 days. There was no statistically significant difference in the area of egg granulomas between the 10-day group and the 30-day group (t=0.975, P=0.332). Masson staining and liver hydroxyproline content detection showed significant fibrosis in the liver. The qPCR results showed that, compared with the control group, the expression levels of fibrosis marker genes, such as α⁃Sma (alpha smooth muscle actin), Col1a1 (collagen type Ⅰ alpha 1), and Tgfb1 (transforming growth factor beta 1), were significantly increased (t=6.380, 7.533, 5.314; P=0.002, 0.001, 0.007), and then decreased on the 30th day, with no statistical difference compared to the control group (t=0.940, 1.529, 1.746; P=0.778, 0.543, 0.457). At the same time, the expression levels of Th1 type immune response-related genes, such as tumor necrosis factor alpha (Tnf), interferon gamma (Ifng), and Th2 type immune response-related genes, such as interleukin-5 (Il5), interleukin-13 (Il13), significantly increased 10 days after eggs injection (t=6.163, 4.589, 5.651, 5.367; P=0.003, 0.018, 0.020, 0.009). In addition, there was no significant change in the levels of AST and ALT in the serum of each group of mice (t=0.982, 3.450; P=0.771, 0.074. t=1.164, 0.564; P=0.697, 0.917). Conclusions A mouse model of schistosomiasis liver disease induced by portal vein injection of worm eggs was constructed. The study provides a new modeling method for studying the mechanism of liver fibrosis in schistosomiasis..

OBJECTIVE: To study the assistant effect of Scutellaria barbata extract (ESB) in 5-fluorouracil (5-FU) chemotherapy. METHODS: A mouse model of transplanted hepatoma H22 was used in this study to evaluate the synergic and attenuating effects of ESB in chemotherapy. Tumor inhibition rate, life span of mice and the toxicity of chemotherapy were observed. The body weight, tumor weight, thymus index and spleen index in H22-bearing mice were also measured. The phagocytotic function of macrophages was studied by observing phagocytization of peritoneal macrophages. RESULTS: The increase of body weight in 5-FU plus ESB groups was higher than that in 5-FU group, and the side effects such as anorexia, abdominal distention and athrepsy were relieved. Compared with untreated group, prolonged lifetime in 5-FU plus high-dose ESB group and 5-FU plus low-dose ESB group was improved. Life prolongation rates in 5-FU plus high-dose ESB group and 5-FU plus low-dose ESB group were 61.46% and 23.59% respectively. High-dose ESB, 5-FU, 5-FU plus low-dose ESB and 5-FU plus high-dose ESB could inhibit the tumor growth, and the tumor inhibition rates were 36.98%, 42.26%, 52.45% and 65.28%, respectively. Thymus index and spleen index were increased significantly in 5-FU plus low-dose ESB group and 5-FU plus high-dose ESB group. White blood cell (WBC) count was decreased obviously in 5-FU group, while the count of WBC was increased in 5-FU plus low-dose ESB group and 5-FU plus high-dose ESB group. The phagocytotic function of macrophages was also increased in 5-FU plus low-dose ESB group and 5-FU plus high-dose ESB group. CONCLUSION: ESB can enhance the effect of chemotherapy, relieve the side effects and improve immune function of mice in chemotherapy. These results suggest that ESB, as a biochemical modulator to enhance the therapeutic effects, is useful in cancer chemotherapy.

Objective To explore the value of B-type natriuretic peptide (BNP) predicting cardiac events after noncardiac surgery in the aged patients. Methods The level of BNP, the score of Goldman analysis and the cardiac risk grade of ACC/AHA guideline were analyzed in 274 aged patients for cardiac outcome after noncardiac surgery. Results Preoperative BNP concentration>100 pg/ml,score of Goldman≥13,and the high or moderate risk grade by ACC/AHA guideline were related with cardiac events. There was no significant difference in the index such as sensitivity,specificity, accuracy,positive predictive value and negative predictive value for cardiac events between BNP level and cardiac risk grade. Compared with the score of Goldman, BNP was more sensitive (100% vs 55.6%)and negatively predictive (100% vs 96.3%) for cardiac events. Conclusion The risk of cardiac events after noncardiac surgery could be predicted with the level of BNP before operation in the aged patient.

Objective:To compare the perioperative complications of carotid endarterectomy with patch angioplasty or primary closure.Methods:The clinical data of 492 carotid endarterectomy patients at the Vascular Surgery Department of Anzhen Hospital from Mar 2003 to Dec 2016 was analyzed retrospectively.Results:There were 364 cases (74%) in the patch angioplasty group and 128 cases (26%) in the primary closure group. The incidence of perioperative ischemic stroke was significantly lower in the patch angioplasty group than that in the primary closure group (0.8% vs. 3.9%, P=0.031), and there was no difference in the incidence of the remaining perioperative complications. By subgroup analysis, the incidence of perioperative ischemic stroke was significantly lower in the patch angioplasty group than in the primary closure group when the diameter of the internal carotid artery was <5 mm (0.7% vs. 6.0%, P=0.001), whereas there was no difference between the two groups when the diameter of the internal carotid artery was ≥5 mm. Conclusions:Carotid endarterectomy with patch angioplasty can reduce the incidence of perioperative cerebral infarction, especially in cases with an internal carotid artery diameter <5 mm.
