Objective To evaluate the potential effect of HLF (Hawthorn leave flavonoids, w/w, 80% flavonoids) against thrombus formation, effect of HLF on hypoxia-treated human umbilical vein endothelial cell (HUVECs) was studied. Method The levels of cytotoxicity and NO upon HUVECs were studied by flow cytometry. Moreover, the level of calcium ion in HUVECs was examined through laser scanning confocal microscopy. Result Data from this study showed that HLF at concentrations of 5 μg/ml and 10 μg/ml decreased the cytotoxicity of hypoxia to HUVECs (P<0.05, P<0.01). The intracellular levels of NO and calcium ion were downregulated by HLF at concentrations of 5 μg/ml (P<0.01; P<0.01) and 10 μg/ml (vs control, P<0.01; P<0.01) too. Conclusion Results observed suggest that HLF protect HUVECs from hypoxia partly through its regulative effect on NO and calcium ion levels.

The process of liver metastasis of colorectal cancer includes tumor cells invasion,survival in blood stream,extravasation to the liver and proliferation. It is involved in series of molecular markers,among which vascular endothelial growth factor and endothelial growth factor receptor are the major targets.

Objective To explore the effect of the prenatal dexamethasone treatment on the preventionof wet lung syndrome in the newborn of elective caesarean section at term. Methods Two hundred cases of elective caesarean section at term (the gestation age was less than 39 weeks) were divided into observation group and control group,with 100 cases in each by random digits table. Observation group was treated with four intramuscular injections of 6 mg dexamethasone in the 24 hours to 7 days before delivery, and control group was treated with 0.9% sodium chloride injection with the same method. The clinical data and the incidence of the wet lung syndrome of the newborn were collected. Results The incidence of the wet lung syndrome of the newborn was 1%(1/100) in observation group and 9%(9/100) in control group,and the incidence of the severity of the wet lung syndrome of the newborn was 1% ( 1/100) in observation group and 2%(2/100) in control group. There were no complication in observation group and 1 case in control group.The incidence and the severity of the wet lung syndrome of the newborn in observation group were less than that in control group significantly (P = 0.009,0.049). Conclusion Prenatal dexamethasone treatment can reduce the incidence of the wet lung syndrome of the newborn and decrease the incidence of the severity and complication of elective caesarean section at term.

Objective To explore the effects of aspirin on formation and dispersion of Pseudomonas aeruginosa (P.aeruginosa) biofilm.Methods The broth microdilution method was used to detect the minimal inhibitory concentration(MIC) of aspirin for P.aeruginosa.The anti-biofilm effects of aspirin on P.aeruginosa were determined on the microtiter plates combined with crystal violet staining.The serial dilution method for counting colony number on microtiter plate was used to explore the effects of aspirin on initial adherence of P.aeruginosa.Results The MIC values of aspirin against PAO1,PA18,PA53 and PA67 strains of Pseudomonas aeruginosa were 5,2.5,5 and 5 mg/mL respectively.Aspirin significantly inhibited the formation and dispersion of the biofilm of PAO1 and PA18 strains (t =5.65,P ＜ 0.05 and t =5.06,P ＜ 0.05 for inhibition;t =6.45,P ＜ 0.05 and t =6.26,P ＜ 0.05 for dispersion) at the concentration of 2.5 mg/mL.Similar effects were also found in the determination for PA67 and PA53 strains(t =6.45,P ＜0.05 and t =6.26,P ＜ 0.05 for inhibition;t =7.82,P ＜ 0.05;t =9.18,P ＜ 0.05 for dispersion) at aspirin concentration of 1.25 and 0.313 mg/mL respectively.Aspirin inhibited the initial adherence of P.aeruginosa at the concentration of 2.5 mg/mL(P ＜0.05).Conclusion Aspirin could significantly inhibit the initial adherence and biofilm formation of P.aeruginosa and disperse the 24 hour-formed mature bioiflm.

Anhedonia, or markedly diminished interest or pleas-ure, is a hallmark symptom of depression.As a psychopathological symptom, anhedonia was first noted in the early 19th century.The neurobiological mechanisms that underline anhedonia and its role in diagnosing depression disorder or evaluating antidepressant response have long been aroused attention for nearly a century.Consequently, there are many measuring methods established in both the animal study and human research, which would be reviewed in the present study.

[Objective] To observe the curative effects and the influence of activity of Superoxide dismutase(SOD) and contents of Maleic dialdehyde(MDA) of Qingchangyukui Gel in Rats with Experimental Ulcerative Colitis. [Method]Ulcerative Colitis model was established in Wistar rats by injecting trinitro-benzene-sulfonic acid (TNBS)into anus, and then treated with Qingchangyukui Gel and salisy-lazosulfa-pyridine(SASP) respectively. Isolating the colon and measuring the SOD and MDA after treating for two weeks. [Results]Colon mucous membrane in the model group had serious erosion, ulcer, damaging of glandular organ, high inflammation grade; activity of SOD in model group was significantly lower than in normal group and contents of MDA increased. The other groups, especially in Qingchangyukui Gel group, had different levels of inflammation repairing, ulcer healing, increasing of SOD and reducing of MDA. [Conclusion]TNBS can cause Colon mucous membrane inflammation and ulcer, reducing of SOD and increasing of MDA , which are the typical pathological change of Ulcerative Colitis; the Qingchangyukui Gel has the effects of increasing the activity of SOD and reducing contents of MDA, therefore it can effectively treat the UC rat.

Objective To investigate CT findings of atypical pheochromocytoma.Methods 18 cases of atypical pheochromocytoma were verified with operation and pathology.2 cases were extra-adrenal pheochromocytoma,3 cases were bilateral or multiple pheochromocytoma,7 cases were non-function pheochromocytoma and malignant pheochromocytoma were 6 cases.Results All atypical pheochromocytoma showed equivalent density mass with necrosis in CT scanning,calcification was rare.Most of them had strong enhancement in parenchyma.Conclusion (1)Atypical pheochromocytoma has high tendency to malignance.(2)CT has high locational and qualitative rate in diagnosing atypical pheochromocytoma but can not different malignance from benign pheochromocytoma,except the mass has metastatic signs.The diagnosis of non-function pheochromocytoma has to consider biochemical and other examination.

Objective To investigate CT features of adrenal neoplasms.Methods 9 cases of rare adrenal neoplasms were verified with operation and histology.3 cases were ganglioneuroma,2 cases were neuroblastoma and the remaining four were cyst,neurofibroma,lipoma and mesenchymoma.Results Adrenal cyst,neuroblastoma and lipoma had their obvious CT features.All adrenal ganglioneuroma,neurofibroma and mesenchymoma had low or equivalent density.Ganglioneuroma and neurofibroma had no enhancement but mesenchymoma had slight or moderate enhancement.Conclusion It is difficult or impossible to distinguish these tumors,except cyst,neuroblastoma and lipoma,from non-function adenoma or pheochromocytoma.
