Notch signaling is one of the most important signaling pathways in vertebrates and inverte -brates.It regulates apoptosis,proliferation,differentiation and so on.The up -regulation,down -regulation or structural changes of Notch signal are closely related to the development of various malignant tumors .In the pres-ent study,four Notch phenotypes(Notch1-4)have been identified,which bind to their ligands respectively (Jag-ged1,Jagged2,Delta1,Delta3,Delta4).Notch plays an important role in a variety of malignant tumors .This review focuses on the role of Notch in a variety of solid malignancies ,including its role in the process of tumor develop-ment and treatment .

Objective To study the pathology and treatment of huge nonhepatic tumors in the right upper quadrant of abdomen.Methods The clinical data of 9 patients with huge nonhepatic tumor in the right upper quadrant of abdomen treated surgically at our hospital from May 2004 to December 2009 were retrospectively analyzed.Results Preoperative imaging failed to define the tumors as nonhepatic in original in 7 patients and operation failed to recognize the origin of the tumors in 2 patients.All the tumors were successfully resected,with combined hemigastectomy in 1 patient,partial resection of the lateral wall of the infrahepatic vena cava in 2,complete resection of adipose capsule of the right kidney in 2,pancreatoduodenectomy plus transverse colectomy in 1,and transection of pancreatic duct of the body and tail of the pancreas and pancreaticojejunostomy in 1.The median operation time was 390 min (318-660 min).The median intraoperative blood loss was 2560 ml (400-6000 ml).The median intraoperative blood transfusion was 2450 ml (0 -5250 ml).The average diameter of the resected tumor was 14.5 cm (11-30 cm),and the average tumor weight was 2465 g (960-5100 g).Postoperative pathological diagnoses showed that 8 patients had malignant tumors and 1 had a potentially malignant and undifferentiated tumor (solid pseudopapillary tumor of pancreas).Perioperative pancreatic anastomotic leak occurred in 1 patient,and there were no severe postoperative complications and operative death in this series.Tumor recurrence was detected 5 months following operation in 1 patient.The 1,2-,3-year survival rates were 100％,56％,33％,respectively.One patient survived for more than 5 years.Conclusions Huge non-hepatic tumors in the right upper quadrant of abdomen could easily be misdiagnosed as hepatic neoplasms.The surgical resection rate was high.The prognosis for patients who received resectional treatment was satisfactory.

Object To study the hemolytic effect of total saponins from Ginseng (Gs), Radix Ophiopogonis (ROs) and Shengmaisan, a compound preparation of the two saponins, and the antihemolytic effect of antioxidants on hemolysis. Methods The percentage of hemolysis was indirectly calculated by measured cyanomethemoglobin, and morphological changes of red blood cells (RBCs) was examined by light microscope. Results Gs did not lead to hemolysis while both ROs and Shengmaisan induced lysis in a concentration dependent manner. RBCs deformation can be observed by light microscopic study. The hemolysis was partly inhibited by addition of glucose or antioxidants including mannitol and ?-tocopherol. Conclusion The intensity of hemolytic effect varied with different saponins present in the compound preparation, and may be associated with the type of saponin and partly due to its ability to enhance lipid preoxidation of RBCs membrane.

The study aims to develop a unified method to determine seven phenolic acids (neochlorogenic acid, chlorogenic acid, 4-caffeoylquinic acid, caffeic acid, isochlorogenic acid B, isochlorogenic acid A and isochlorogenic acid C) contained in honeysuckle flower that is the monarch drug of all the eight Yinqiao Jiedu serial preparations using quantitative analysis of multi-components by single-marker (QAMS). Firstly, chlorogenic acid was used as a reference to get the average relative correction factors (RCFs) of the other phenolic acids in ratios to the reference; columns and instruments from different companies were used to validate the durability of the achieved RCFs in different levels of standard solutions; and honeysuckle flower extract was used as the reference substance to fix the positions of chromatographic peaks. Secondly, the contents of seven phenolic acids in eight different Yinqiao Jiedu serial preparations samples were calculated based on the RCFs durability. Finally, the quantitative results were compared between QAMS and the external standard (ES) method. The results have showed that the durability of the achieved RCFs is good (RSD during 0.80% - 2.56%), and there are no differences between the quantitative results of QAMS and ES (the relative average deviation < 0.93%). So it can be successfully used to the quantitative control of honeysuckle flower principally prescribed in Yinqiao Jiedu serial preparations.

Objective To observe the anti-inflammatory and analgesic effects of CNZ,an optimized prescrition of Liushen Wan based on our previous studies,so as to provide some pharmacological evidence for its further clinical use. Methods Both acetic-acid-induced increased mouse vascular permeability and carrageenan-induced mouse footpad edema were used to study the anti-inflammatory activity of CNZ.Meanwhile,its analgesic activity was evaluated in mice model of pain induced by thermal stimulus and acetic acid.The above activities were compared with those of Liushen Wan.Results CNZ significantly reduced acetic-acid-induced dye leakage at the doses of 16,32 and 64mg/kg after single oral administration.Meanwhile,CNZ at the two higher doses also markedly inhibited carrageenan-induced foot- pad edema,which exerted the strongest effect at 3 hours after carrageenan injection,and lasted over 5 hours.On the other hand,CNZ remarkably suppressed acetic-acid-induced writhing response at low,moderate-and high-doses, and significantly prolonged pain threshold in hot plate assay at moderate-and high-doses 0.5 hour after oral adminis- tration,lasting over 3 hours.Overall,its potency was similar to that of Liushen Wan.Conclusion CNZ has significant anti-inflammatory and analgesic activities.

Objective:To investigate the clinical manifestations and distribution characteristics of dry eye patients with ocular discomfort symptoms in Jilin Province, and to analyze the relationship between the risk factors associated with dry eye and its severity. Methods:The secondary or tertiary hospitals in Jilin Province were randomly selected and used as screening bases from July 2014 to August 2015.1 173 people initiative to the hospital for eye examinations after publicity were selected.Questionnaire was used to collect the subjective symptoms of dry eye.The breakup time(BUT) of tear film, corneal fluorescein staining, meibomian gland and tear secretion were examined and the detection rate and risk factors of dry eye of the dry eye patients with different clinical characteristics were analyzed.Results: A total of 1 122 people was actually surveyed, 896 individuals were diagnosed as dry eye, and the prevalence rate was 79.8%. The prevalence rate of the females was higher than of the males(χ2 =4.070,P<0.05).The prevalence of dry eye between different ages was statistically significant(χ2 =61.547,P<0.05).The multivariate Logistic regression analysis results showed that the age ≥40 years (40-49 years,OR =6.313,95% CI: 3.498-11.393;50-59 years,OR =6.919,95% CI: 3.876-12.351;60-69 years,OR =5.175,95% CI: 2.650-10.104;over 70 years,OR =9.508,95% CI: 3.608-25.061), moderate grade of meibomian gland dysfunction(MGD) (OR =2.123,95% CI: 1.186-3.803), and the patients with rheumatoid arthritis (OR =2.186,95% CI: 1.098-4.353) and eye surgery (OR =3.692,95% CI: 1.204-11.323) were the risk factors for dry eye. While the occupation of farmer was a protective factor for dry eye (OR =0.351, 95% CI: 0.135-0.917).Conclusion:Age, occupation, MGD grade, rheumatoid arthritis and eye surgery history affect the occurrence of dry eye to a certain extent. So enough attention and appropriate health guidance should be given to reduce the incidence of dry eye.

Objective To investigate the correlation between ADAM33 T1, S2 gene polymorphism and Bronchial asthma risk in china. Methods We retrived the relevant published studies about ADAM33 T1, S2 gene polymorphism and bronchial asthma risk. Then we divided the population into Chinese and other Asian population. Odds ratio (OR) of Case group and control group was selected as the effect index. Stata 11.0 software was used to calculate heterogeneity test, ORs and 95%CI of two areas, and gave the forest plot and funnel plot of meta results. Results A total of 27 studies were included in this analysis,18 studies in ADAM33 T1 site were 3881 cases in case group, and 3780 cases in control group;and 14 studies in ADAM33 S2 site were 3222 cases in case group, and 3513 cases in control group. Additive model, dominant model, recessive model of ADAM33 T1 in Chinese had association with the susceptibility of bronchial asthma. The results were OR=1.488, 95% CI:1.002-2.167 in Additive model, OR=1.619, 95%CI:1.059-2.475 in dominant model;OR=2.523, 95%CI:1.910-3.333 in recessive model. Three models of ADAM33 T1 in other Asian country had no association with the susceptibility of Bronchial Asthma. Three gene model of ADAM33 S2 in Asian had no association with bronchial asthma susceptibility. Except ADAM33 T1 polymorphism in recessive model, other mode of T1, S2 had no publication bias in Chinese population. Conclusion There are association between ADAM33 T1 gene polymorphism and bronchial asthma, but ADAM33 S2 gene polymorphism and bronchial asthma have no association in Chinese population.

Objective To evaluate perfusion computed tomography in the assessment of portal vein pressure changes in an experimental dog model of liver cirrhosis and portal hypertension.Methods The canine model of cirrhosis and portal hypertension was induced by portal vein stenosis with combination of systemic thioacetamide(TAA) feeding in drinking water.All of the Beagles in control group and cirrhotic group underwent hepatic perfusion on a spiral CT scanner.The parameters of hepatic perfusion were calculated by the method of deconvolution.The portal vein pressure was measured by a laparotomy surgery.Results ① In control group, the portal vein pressure was ( 14.5 ± 2.2) cm H2O, while it was (23.1 ± 2.8) cm H2O in PHT group, there was significant difference in the portal vein pressure between the two groups (P＜0.05).② The blood flow(BF) was (112 ±14) ml·100 g-1·min-1 in controls, while ( 96 ± 11) ml·100 g-1·min-1 in PHT group; the blood volume ( BV ) in control group and PHT group was (10 ±3) ml·100 g-1 and (11 ± 5) ml· 100 g-1, respectively; the mean transit time( MTT) was (7.1 ± 2.0) s and (10.4 ± 3.5) s, respectively; the hepatic arterial fraction (HAF) was ( 24 ± 5) % and ( 37 ± 6)% , respectively; the hepatic arterial perfusion (HAP) was(27 ±6) ml·100 g-1·min-1 and (35 ±5) ml·100 g-1·min-1, respectively; the portal venous perfusion (PVP) was (85 ± 13) ml·100 g-1·min-1 and (61 ±11) ml·100 g-1·min-1, respectively.There was significant difference in all parameters between the two groups except the parameter BV(P ＜ 0.05).③ In PHT group, the PVP and BF were negatively correlated with the portal vein pressure, while positively correlated with MTT and HAF.Portal vein pressure was negatively correlated with PVP, the equation, Y = 36.624 -0.219X, was deduced with linear regression analysis, by which the portal vein pressure in PHT Beagles was ( 23.2 ± 2.4) cm H2O, which was correlated with the observed by laparotomy value (23.1 ± 2.8) cm H2O (r = 0.843, P ＜ 0.05).Conclusion CT perfusion is a new non-invasive and effective method for assessment of portal vein pressure.

Objective To investigate the value of multi-slice computed tomography angiography (MSCTA)in the detection of intracranial micro-aneurysms(aneurysm≤3 mm in maximal diameter, IMA).Methods The clinical history and images of 826 patients with suspected intracranial aneurysms were retrospectively analyzed.All patients underwent MSCTA on 16-slice row CT before hospitalization(from 2 h to 4 d after symtom onset).All intracranial aneurysms were confirmed by digital subtraction angiography (DSA), three-dimensional rotational angiography (3DRA) or surgery.Two independent radiologists assessed all the images.The MSCTA findings were compared with the DSA/3DRA results.The sensitivity, specificity, and accuracy of MSCTA for diagnosis of IMA was calculated.The diagnostic consistency between DSA/3 DRA and MSCTA was determined by Kappa statistics.The prevalence of multiple aneurysms between the group of patients with IMA and the group of patients without IMA was evaluated by Chi-square test Results A total of 889 aneurysms in 788 of the 826 patients were detected.Among them, 706 patients had single aneurysm and 82 patients had multiple aneurysms.No aneurysms were detected in 38 patients.Among the 212 patients who underwent DSA/3 DRA, 271 aneurysms were found and 232 were IMA.MSCTAdetected 229 IMA.There was 1 false-positive finding and 4 false-negative findings by MSCTA.The sensitivity, specificity and accuracy of MSCTA for IMA was 98.3% (228/232), 97.4% (38/39), 98.2% (266/271).There was excellent agreement between two techniques (Kappa=0.927, P<0.05).The prevalence of multiple aneurysms was 21.2% (45/212) in the patient group with IMA and 6.4% (37/576) in the group without IMA.There was statistically significant difference between the two groups (X~2=36.421, P<0.01).Conclusions The detection value of IMA by MSCTA was high.The cutoff level of diameter of intracranial IMA should be adjusted from 4-5 mm to ≤3 mm.
