To explore the feasibility of rapid proto-typing ( RP) technology in the treatment of Standford type A aortic dissection. 5 patients with Standford type A aortic dissection received computed tomography angiography (CTA) of their aortas. The CTA images were then processed by 3D reconstruction with MIMICS16. 0 in order to create aortic dissection models through RP technology based on real patient aorta size with a ratio of 1 ∶ 1 . Accord-ing to these models, the surgeons were able to fully understand the aortic diseases of patients, thus establish indi-vidualized treatment strategies for each patient. Besides, the surgeons simulated operations on the models, which helped them achieve better results in real surgery. These patients experienced no post-operative complications and were discharged from hospital with recovery. In conclusion, RP technology can provide adequate preoperotive prep-arations for patients with Standford type A aortic dissection, improve operation efficiency and accuracy in aortic dis-section and guide precise proximal anchoring of stents during intracavitary therapy.

This study was aimed to evaluate effect of Qinghua Granules (QHG) on glycometabolism, pancreatic islet function and oxidative stress in type-2 diabetics with heat syndrome. A total of 60 cases of type-2 diabetics with heat syndrome (according to the Syndrome Element Syndrome Differentiation) were enrolled in the clinic of the Department of Endocrinology and Metabolism, Shuguang Hospital Affiliated to Shanghai University of Tradi-tional Chinese Medicine. The average age of enrolled cases was (57.9 ± 6.9) years. Enrolled cases were randomly divided into the treatment group and the control group. The original hypoglycemic plan was continued to use. In the treatment group, QHG was administrated. And in the control group, placebo was given. The administration dosage in both groups was one package per day. The treatment course was 12 weeks. The fasting and postpran-dial (120 min after standard meal) blood samples before and after medication were collected. The main evalua-tion indexes were fasting plasma glucose (FPG), postprandial plasma glucose (PPG) and hemoglobin A1c (HbA1c). The secondary evaluation indexes were homeostasis model assessment (HOMA2-%B, HOMA2-%S, HOMA2%-IR), superoxide dismutase (SOD), glutathione peroxidase (GSH-PX), maleic dialdehyde (MDA), total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL) and low-density lipoprotein (LDL). The anal-ysis of variance was used in the comparison of efficacy between two groups . The results showed that HbA1c in the treatment group was obviously reduced, and HOMA2-%B was obviously increased. There was no significant changes in the control group ( P = 0 . 044 , P = 0 . 016 ) . In the treatment group , SOD increased obviously , MDA reduced obviously. There was no significant change in the control group. There was difference b etween two groups (P = 0.011, P = 0.049). There was no change on blood lipids or other evaluation indexes. It was conclud-ed that QHG is effective in the improvement of glycometabolism, islet β-cell functions and oxidative stress in type-2 diabetics with heat syndrome .

Objective To evaluate the left ventricular twist in patients with coronary heart disease (CHD) with two-dimensional strain echocardiography (2DSE). Methods Thirty-eight patients with CHD and 31 control subjects proved with selected coronary angiography were enrolled. Two-dimensional images from LV short-axis views at the levels of mitral annulus and apex in 3 continuous cardiac cycles were recorded. LV ejection fraction (LVEF) was calculated with bi-plane Simpson's method, torsion and torsional rate were obtained in each plane, and the corresponding curve was accessed. Results No statistical difference of conventional echocardiographic parameters such as LV diameter, left atria diameter, LVEF, FS, E/A and E-wave deceleration time were detected, while significant difference of torsional direction (P＜0.01) and global torsion rate (P＜0.05) were found between the two groups. Conclusion The global torsional rate and torsional direction have higher sensitivity than conventional echocardiography in the diagnosis of CHD.

Objective:To observe the effect of moxibustion on learning and memory abilities, corticosterone and glucocorticoid receptor (GR) in subacute aging rats. Methods:Twenty four Sprague-Dawley (SD) rats were randomly divided into a normal group, a model group and a moxibustion group, 8 rats in each group. Rats in the model group and the moxibustion group were subcutaneously injected with 25% D-galactose [125 mg/(kg·bw)] for 40 d continuous; rats in the normal group were injected with saline at the same position for 40 d continuous. Rats in the moxibustion group were given mild moxibustion at bilateral Shenshu (BL 23) at the same time of modeling; rats in the normal group and the model group were only identically grabbed without moxibustion for 40 d. The learning and memory abilities of rats were observed using the Morris water maze at the end of the experiment. Abdominal aorta blood and thymus were collected after water maze experiment. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum corticosterone level, and immunohistochemical method was used to detect the expression of thymus GR. Results:Compared with the normal group, rats in the model group showed that a significantly longer escape latency time (P<0.01) on the third and the fourth days; number of times crossing the platform in 70 s significantly reduced (P<0.01); activity times in the fourth quadrant significantly decreased (P<0.05); serum corticosterone levels increased (P<0.01); thymus GR expression decreased (P<0.05). Compared with the model group, rats in the moxibustion group showed that the escape latency times were significantly shorter on the third, the fourth and the fifth days (P<0.01,P<0.05); number of times crossing the platform in 70 s significantly increased (P<0.05); activity times in the fourth quadrant significantly increased (P<0.05); serum corticosterone levels decreased (P<0.05); thymus GR expression increased (P<0.05). Conclusion:Moxibustion could improve the learning and memory abilities of subacute aging rats, down-regulate serum corticosterone levels, and increase thymus GR content.

Objective: To investigate right ventricular function in patients with pneumoconiosis, and to provide a basis for quantitative diagnosis and treatment of pneumoconiosis in clinical practice. Methods: A total of 43 patients with pneumoconiosis who were hospitalized consecutively in Shijiazhuang Prevention and Treatment Center for Occupational Diseases from May 2015 to May 2016 were enrolled, and according to the stage of pneumoconiosis, they were divided into stage I group with 16 patients, stage II group with 14 patients, and stage III group with 13 patients. A total of 16 healthy subjects were enrolled as control group. Echocardiography was performed and the relevant parameters were recorded, i.e., right ventricular transverse diameter (RVTD), tricuspid annular plane systolic excursion (TAPSE), and right ventricular myocardial performance index(Tei index). Results: There were significant differences in Tei index and TAPSE between all groups (P <0.05) except between the stage I group and the control group in terms of Tei index (P>0.05) and between the stage I group and the stage II group in terms of TAPSE (P>0.05). Right ventricular Tei index was negatively correlated with TAPSE (r=-0.547,P<0.05). Conclusion A combination of right ventricular Tei index and TAPSE can be used for early quantitative evaluation of right ventricular function in patients with pneumoconiosis.

Objective: To observe the effect of moxibustion on the colonic mucosal barrier of rats with ulcerative colitis (UC) induced by dextran sulfate sodium (DSS). Methods: Forty male Sprague-Dawley rats were randomly divided into a normal group and a modeling group, with 20 rats in each group. Rats in the modeling group were subjected to preparing experimental UC models by drinking 4％ DSS for seven consecutive days. Two modeled rats and two normal rats were randomly selected for model identification. After the success of UC model was confirmed, the remaining 18 modeled rats were randomly divided into three groups, a model group, a model + herbal cake-partitioned moxibustion group, and a model + mild moxibustion group, with six rats in each group; the remaining normal rats were randomly divided into three groups, a normal group, a normal + herbal cake-partitioned moxibustion group, and a normal + mild moxibustion group, with six rats in each group. After 7 d of intervention with the herbal cake-partitioned moxibustion or the mild moxibustion, hematoxylin-eosin (HE) staining technique was used to observe the pathological changes of colon tissue under a light microscope; Western blotting and/or immunohistochemical techniques were used to detect the protein expression levels of Occludin, Claudin, junction adhesion molecular 1 (JAM1), mucin 2 (MUC2), and transforming growth factor beta1 (TGF-β1) in rat colon tissue. Results: Compared with the normal group, the colon tissue was severely damaged, the pathological score was significantly increased, and the protein expression levels of Occludin, Claudin, JAM1, MUC2, and TGF-β1 were significantly decreased in the model group (P<0.01); while there were no significant differences in the colonic histopathological score, protein expression levels of Occludin, Claudin, JAM1, MUC2, and TGF-β1 in the normal + herbal cake-partitioned moxibustion group and the normal + mild moxibustion group (P>0.05). Compared with the model group, the model + herbal cake-partitioned moxibustion group and the model + mild moxibustion group showed repaired colon tissue, ulcer healing, significantly reduced pathological score, and significantly increased protein expression levels of JAM1, MUC2, and TGF-β1 (P<0.05); the Occludin protein expression level in the colon tissue of the model + mild moxibustion group was increased (P<0.01). Conclusion: Neither herbal cake-partitioned moxibustion nor mild moxibustion influences the colonic histopathology and intestinal mucosal barrier-related protein expression in the normal rats; both herbal cake-partitioned moxibustion and mild moxibustion can up-regulate the protein expression levels of JAM1, MUC2, and TGF-β1 in the colon tissue of UC rats. Mild moxibustion can up-regulate Occludin protein expression. This may be a mechanism of moxibustion in reducing colonic mucosa inflammation in UC.

OBJECTIVETo evaluate the effect of preoperative transcatheter arterial chemoembolization(TACE) on apoptosis of hepatocellular carcinoma (HCC) cells.

METHODSA total of 136 patients with HCC underwent liver resection. One to five courses of TACE prior to liver resection were performed in 79 patients (TACE group), in which one to four courses of chemotherapy alone were performed in 11 patients (group A), one to five courses of chemotherapy combined with iodized oil were performed in 33 patients (group B), one to three courses of chemotherapy combined with iodized oil and gelatin sponge were performed in 23 patients group C) and one to three courses of chemotherapy combined with iodized oil, ethanol and gelatin sponge were performed in 12 patients (group D). The other 57 patients only received liver resection (non-TACE group). The extent of apoptosis was analyzed by transferase-mediated dUTP nick end labeling (TUNEL) staining. The expressions of Bcl-2 and Bax protein were detected by immunohistochemical method.

RESULTSThe apoptotic index(AI) and level of Bax protein in HCC cells were significantly higher in groups A, B, C and D than those in the non-TACE group (P < 0.05). The level of Bcl-2 protein and ratio of Bcl-2 to Bax protein of HCC cells were significantly lower in Groups A, B, C and D than those in the non-TACE group (P < 0.05).

CONCLUSIONPreoperative TACE regimens may enhance apoptosis of HCC cells by up-regulating the expression of Bax protein and down-regulating the expression of Bcl-2 protein and ratio of Bcl-2 to Bax protein expression.
