To evaluate the effectiveness of comprehensive psychological intervention for reducing the preoperative stress response in sterility women. Forty sterility women were equally divided into intervention group and control group. Heart rate(HR), blood pressure(BP), Zung anxiety grade and depression grade scores(SAS, SDS) were recorded; serum concentrations of glucose (GLU), cortieosteroid (Cor), adrenocorticotropic hormone(ACTH) and angiotensin (A Ⅱ) were measure in both groups at admission and before operation. These parameters before surgery were significant higher than those at admission for control group(P<0.05); but there were no significant differences for intervention group (P>0.05). The results indicate that comprehensive psychological intervention can reduce the preoperative stress response of sterility patients.

Objective To analyze the CT findings of benign lymphoepithelial lesion (BLEL) of major salivary glands.Methods The CT findings of 11 cases with BLEL which were clinically and pathologically confirmed were analyzed.The relevant literatures were reviewed.All the patients received plain CT.Among them,5 patients had contrast CT as well.The location,number,shape,margin,density,and enhancement characteristics of the lesions were observed.Results Of 11 BLEL,8 lesions were located in the parotid gland,three in the submandibular gland.There were 7 cases with bilateral multiple lesions,and 4 cases with unilateral solitary lesion.BLEL of major salivary gland could be classified into three types according to the CT findings,including multinodular type,solitary mass type,and diffusely infiltrating type.Multinodular type was the most common type.The typical CT findings of the lesion included diffusely enlargement of bilateral parotids and (or) submandibular glands,heterogeneous increase of density of the parenchyma with multiple soft tissue density nodules,and multiple cystiform hypodense.On contrast-enhanced CT,the lesions mostly manifested as heterogeneous enhancement.The solid part of the nodules showed moderate or marked enhancement.However,the cystiform hypodense showed no enhancement.Conclusion Although the CT findings of BLEL of major salivary glands are variable,they still share some common characteristics,which are useful in the clinical diagnosis.

PurposeTo investigate the correlation between iodine concentration and clinical severity of acute pancreatitis (AP) through the quantitative evaluation with dual-energy spectral computed tomography (DESCT), so as to find out an effective imaging technology in the evaluation of clinical severity of AP.Materials and Methods Sixty patients with AP confirmed clinically (AP group) and 30 patients with normal pancreas (control group) were retrospectively analyzed. All the patients underwent enhanced CT scan in the spectral imaging mode. Iodine concentration and normalized iodine concentration (NIC) were respectively measured during arterial phase and portal phase in the material-decomposition images by using a spectral imaging viewer (GSI Viewer). Results Iodine concentration and NIC were significantly higher in the control group than in the AP group (P<0.05,P<0.001). In the AP group, according to Ranson grading, 24 patients were in the mild grade, 20 patients were moderate, and 16 patients were severe. Iodine concentration and NIC decreased along with the increase of their Ranson grade. There were significant difference in iodine concentration and NIC among the three subgroups (iodine concentration on arterial phase:F=8.776,P<0.01; iodine concentration on portal phase:F=4.019,P<0.05; NIC on arterial phase:F=12.700,P<0.001; NIC on portal phase:F=8.732,P<0.01). Iodine concentration and NIC on arterial and portal phases in the mild grade group were both significantly higher than those in the moderate grade group (P<0.05); however, iodine concentration on arterial and portal phases, and NIC on arterial phase in the severe grade group were significantly lower than those in the moderate grade group (P<0.05).Conclusion DESCT can analyze hemodynamic changes in AP quantitatively, which is of great value in evaluating changes in AP of each grade.

AIM: To investigate the effect on growth and activity of telomerase in esophageal carcinoma cells by inhibiting ubiquitin-proteasome pathway(UPP). METHODS: The esophageal carcinoma cell strain Eca9706 was treated with MG-132 to inhibit its UPP specially. The effect of growth suppression on cells was evaluated with MTT assay, morphologic changes of cells were observed under microscope, cell cycle and apoptosis were detected by flow cytometry (FCM). DNA fragment analysis was used to confirm the presence of apoptosis. The activity of telomerase was detected. RESULTS: MG-132 had obvious inhibitory effect on the growth of Eca9706 cells in a dose and time-dependent manner. Obvious pathologic change of cells were observed under microscope, cells became round, small and exfoliating. The FCM analysis showed that the ratio of esophageal carcinoma cells of G_1 phase increased and a obviously apoptotic sub-G_1 peak was found. Agarose electrophoresis showed marked ladder. The activity of telomerase was obviously inhibited. CONCLUSIONS: MG-132 significantly inhibits the growth and the activity of telomerase of Eca 9706 cells. These findings indicate that inhibiting UPP is a new strategy for the treatment of esophageal carcinoma. [

Objective To investigate the expression profile of mRNAs in brain samples collected from pronuclear transfer (PNT) mice. Methods Female CD-1 mice were superovulated, and zygotes were collected after mating with adult male mice. Zygotes with two pronuclei were selected for pronuclear transfer manipulation, and then the reconstructed zygotes were transferred into the oviduct of pseudopregnant female mice. The infant mice obtained from pronuclear transfer were called PNT group, while the embryoes that were not performed pronuclear transfer was regarded as control group. Total RNA were extracted from brain samples of both PNT and control mice, and cDNA were labeled with fluorescent dye. Genes that were differentially expressed were identified using the Agilent mouse mRNA array. Gene ontology analysis and pathway analysis were also completed. Results Compared with control group, 392 mRNAs were expressed differentially, which showed more than 2.0 times variation and statistical significance, accounting for 1.7% of all mRNAs. Among those 366 mRNAs were up-regulated and 26 mRNAs were down-regulated. Eleven mRNAs came to 4.0 times variation in total. Gene ontology analysis indicated that differentially expressed genes were significantly enriched in alternative mRNA splicing, small GTPase mediated signal transduction, regulation of insulin receptor signaling pathway, hydrolase activity, transmembrane transporter activity and pyrophosphatase activity. Significant enriched pathway terms contained ion channel transport, fatty acid metabolism, butanoate metabolism, triacylglycerol and ketone body metabolism. Conclusion Pronuclear transfer might influence some key metabolism process in mouse brain.
