Objective:To evaluate the role of using the double body position CT(DBP-CT)in the staging of advanced gastric cancer.Methods:We performed CT examination in 85 patients with advanced gastric cancer which were divided into the double postion group(55 cases)and the single position group(30 cases),after oral intake water agent.The preoperative CT findings of each group was compared with surgical findings respectively and the accuracy in the CT staging of advanced gastric cancer of each group was estimated.Results:The accuracy in the preoperative CT staging of double position group was 89.09%,and in single postition group was 60%.There was a significant difference(P＜0.05).Conclusion:Our findings show that the DBP-CT is surperior to the single position group in finding lesion,confineing the range of the tumour,and determing the degree of adjacent invasion.It can improve the diagnostic accuracy in the preoperative staging of advanced gastric cancers significantly.

Objective To evaluate the role of different kinds of body positon in the stomach CT scanning.Methods It included 30 normal adults who underwent CT scanning in four differnent kinds of body positions.The relationship between the body position and the image appearence in the each part of stomach has been analysed.Results The results showed that the adjusting of body position was useul in revealing gastric wall and perigastric organs.The best imaging result of fundus ventriculi part of stomach can be obtained with the head down and the feet high position while patients lie on his back.The best body position to reveal corpus ventriculi part is in prone position and the best body position to reveal pars pylorica part is in right lateral position.There is a very significant difference between supine position and the best revealing position of each part of stomach prespectively(?

To investigate the relationship between serum glutamic acid decarboxylase antibody (GAD-Ab)titer and the first-phase insulin release (1PH)in newly-diagnosed type 2 diabetic patients. 1053 newly-diagnosed type 2 diabetic patients were divided into 3 groups, including 71 individuals with GAD-Ab≥1 U/ml (positive group), 171 individuals with GAD-Ab ranging from 0 to 1 U/ml (negative-1 group), and 811 individuals with GAD-Ab=0 (negative-2 group). IPH was evaluated by arginine stimulation test. In the patients of negative-2, negative-1, and positive groups, the respective values of 1 PH were subsequently decreased significantly (P< 0. 01) , and the detection rates of the decreased insulin secretion were 74. 85%, 87. 13%, and 100%, respectively. Stepwise regression analysis indicated that disease duration, GAD-Ab titer, HbA_1C, and body mass index were the major independent contributing factors. The titer of GAD-Ab has an important impact on 1PH defect in type 2 diabetic patient. Detection of GAD-Ab not only provides an evidence for clinical type, but would also be helpful in determining the islet β-cell function.

Objective To analyze the risk factors of retinopathy and nephropathy in hospitalized patients with type 2 diabetics. Methods 24 h-urinary albumin was measured in 2 338 patients with type 2 diabetic hospitalized from July, 2002 to Sep, 2008 in our hospital. All the subjects were divided into normalbuminuria group (NA) and diabetic nephropathy group (DN), the latter consisted of microalbuminuria group (MAU) and macroalbuminuria group (CAU). All the patients were divided into normal retina group (NR) and diabetic retinopathy group (DR), the latter consisted of background diabetic retinopathy group (BDR) and proliferative diabetic retinopathy group (PDR) according to fundus photography. Results (1) The percentages of DR and DN of this cohort were 28.8% and 28.7%, respectively.The percentage of DR and DN had no statistical difference between male and female (27.8% vs 30.0%;29.6% vs 27.6%, P>0.05). (2) The percentage of DR was 23.1%, 37.7% and 56.6% in NA, MAU and CAU group, respectively. There was significant difference among different albuminuria group (P<0.01). (3) The percentage of DN was 23.1%, 41.1% and 59.3% in NR, BDR and PDR group, respectively. There was significant difference among different DR group (P<0.01). (4) Combined with DN, diabetes duration, systolic pressure, hemoglobin A1C, triglyceride were independently associated with DR by Logistic regression analysis. Meanwhile, combined with DR, systolic pressure, hemoglobin A1C, and triglyceride were all independently associated with DN. Conclusions The onset and progression of microvascular complications in type 2 diabetic patiens are correlated with hemoglobin A1C and systolic pressure. Diabetic retinopathy is closely correlated with diabetic nephropathy.

OBJECTIVETo study the expression of Skp2 in cervical squamous cell carcinoma (SCC) and its precancerous lesions, and to investigate its relationship with human papillomavirus (HPV) infection.

METHODSThe expression of Skp2 protein and HPV16/18 DNA was determined using immunohistochemistry and in-situ hybridization in 30 cases of normal cervical squamous epithelium, 29 cases of low-grade intraepithelial neoplasia, 31 cases of high-grade intraepithelial neoplasia and 31 cases of cervical SCC.

RESULTSSkp2 expression was not detected in normal cervical squamous epithelium and no significant difference was obtained statistically on Skp2 expression between normal cervical squamous epithelium and low-grade intraepithelial neoplasia (P > 0.05). However, the expression of Skp2 gradually increased with elevation of epithelial lesion grading in an order from low to high grade and to cervical SCC (P < 0.01). The positive rate of HPV16/18 DNA in cases of normal cervical squamous epithelium, low-grade, high-grade intraepithelial neoplasia and cervical SCC was significantly different (P < 0.01), although both high-grade intraepithelial neoplasia and cervical SCC had a similar high HPV infection rate up to 96.8%. There was no correlation obtained between Skp2 expression and HPV16/18 infection in low-grade intraepithelial neoplasia. In contrast, expression of Skp2 and HPV infection were significantly correlated in both high-grade intraepithelial neoplasia and cervical SCC (gammaH = 0.373, gammaC = 0.416, P < 0.05).

CONCLUSIONSAbnormal expression of Skp2 is present mainly in high-grade cervical intraepithelial neoplasia and invasive carcinoma, which may be considered as a surrogate marker for the high-grade lesions. Skp2 may play a key role in the development of cervical squamous carcinoma induced by HPV16/18 infection, through E7-Skp2-Rb signaling pathway.

OBJECTIVEJianyate Hao (JYTH) , a traditional Chinese medicine formula, which has been used effectively to treat depression in the past ten years. The purpose of this study was to explore the antidepressant effect of acute administration with JYTH and its possible mechanism.

METHODthe animals behavioral despair models of depression, the tail suspension and forced swimming tests, were used to explore the antidepressant effects of JYTH. In addition, the locomotor activity test was used to detect the change of locomotor activity. The monoamine oxidase activity in the mouse brain was also determined by using fluorospectrophotometry.

RESULTJYTH (17.5, 35, 70 g x kg(-1), ig) could decrease the duration of immobility in both tail suspension and forced swimming tests, and the effect of JYTH (35 g x kg(-1) ig) was resembling imipramine (10 mg x kg(-1), ip) in relieving depression. And the effective doses (17.5, 35, 70 g x kg(-1), ig) did not alter locomotion activity. Moreover, JYTH (35 g x kg(-1), ig) was found to inhibit monoamine oxidase activity in the mouse brain.

CONCLUSIONThese findings suggest that JYTH exerts antidepressant effect in animals behavioral despair tests and the underlying mechamism may involve the inhibition monoamine oxidase activity in the mouse brain.

This study is to investigate the protective effect of longistyline A against corticosterone-induced neurotoxicity in PC12 cells. While PC12 cells were exposed to 100 micromol x L(-1) corticosterone for 48 h, cell survival rate was reduced and lactate dehydrogenase (LDH) release increased. In parallel, corticosterone caused significant elevations of DNA fragmentation, [Ca2+]i and caspase-3 activity. However, when the PC12 cells were incubated with longistyline A (4.0, 8.0 and 16.0 micromol x L(-1)) in the presence of 100 micromol x L(-1) corticosterone for 48 h, the effects were evidently alleviated, but dose-dependent manner was not obvious. In summary, longistyline A could generate a neuroprotective effect against corticosterone-induced neurotoxicity in PC12 cells possibly by decreasing [Ca2+]i and caspase-3 activity.
