Objective　To assess the CT manifestations and diagnostic value in the pancreatic tuberculosis(PTB)with review of the literatures. Methods　All cases of PTB proved by surgery or biopsy were examined with plain and enhanced CT scans. Results　The CT findings in one case with multiple-nodular type of PTB were diffuse enlargement of the pancreas with multiple, nodular, and low-density lesions; The nodular lesions had peripheral enhancement. 7 cases of local type of PTB encroached on pancreatic head. 4 cases showed local soft tissue masses with multiple flecked calcifications in 2 cases and mild enhancement in one case; Cystic masses was found in 2 cases, with mural calcification in 1 case and multiloculated cystic mass in 1 case, respectively; Massive pancreatic head calcification was demonstrated in one case. In these 8 cases of PTB, the lesion extended out of pancreas in 4 cases, including abdominal tuberculous lymph nodes, tuberculous peritonitis, and hepatosplenic tuberculosis. Conclusion　CT findings of PTB were various but had some characteristics. Pancreatic masses with multiple flecked calcification or mild enhancement could suggest the diagnosis. Abdominal tuberculosis accompanied with the pancreatic lesion, especially tuberculous lymph nodes, was highly suggestive of the diagnosis of PTB.

AIM: To observe the expression of apoptosis-related proteins in hippocampal neurons of (ovariectomized) (OVX) rats and explore the neuroprotective mechanism of the App17-mer peptide. METHODS: Female Wistar rats were randomly divided into three groups. Bilaterally ovariectomized rats with injection of App 17P peptide (3.5 ?g in 0.1 mL/per rat, three times a week) formed the experimental group (17P+ OVX group). Anti-AIF, Bcl-2 and Bax antibodies were applied in the immunohistochemistry experiment. TUNEL was employed to detect apoptosis. RESULTS: The number of apoptotic neurons was clearly higher in hippocampal and cortex in OVX group than that in OVX+17P group. Immunohistochemistry demonstrated the increased expression of AIF, Bax in hippocampal neurons of OVX group. OVX group showed a significantly reduced expression of Bcl-2 in hippocampal neurons. Hippocampal tissue from OVX group showed the increased expression of AIF, Bax, and showed diminished expression of Bcl-2, treating with App17-mer peptide normalized the expression of these proteins. CONCLUSIONS: The expression of apoptosis-related proteins were abnormal in the OVX rats, App17-mer peptide normalized these changes. Estrogen deficiency induced neuronal apoptosis, and App17-mer peptide diminished apoptosis.

Serum sialic acid (SA) levels were detected by neuraminidase method in 366 patients with malignant tumor, 40 patients with benign diseases and 40 healthy subjects.For 277 malignant tumor patients, serum SA levels were monitored before and after treatment.The serum SA levels in malignant tumor group were significantly higher than those in benign diseases and control groups (P ＜0.01 ), but there were no differences between normal and benign groups (P ＞0.05 ).Serum SA levels were decreased in malignant tumor patients with remission and stable disease after treatment.In remission or stable patients the decrease of serum SA levels occurred in the first three months and no changes were found from the fourth to sixth month; meanwhile SA levels were elevated in patients with instablc condition.

The purpose of this study was to compare eating habits and food attitudes between depressed and normal adults. The subjects were selected (n = 6217) from those who participated in the 2008 Korean National Health and Nutrition Examination Survey (KNHANES IV). The subjects were divided into the depressed (DG, n = 841) and normal groups (NG, n = 3969). DG was those who have depression now or who have experienced depressing feelings more than two weeks or per year. The general characteristics, anthropometric measurement, eating habits, the dietary guideline recognition and practices were compared by using chi-square test and t-test. Also the partial correlations were analyzed by SAS (Statistical analysis system, version 9.1) program. There was a significantly higher rate of DG among the female (74.32%), with low education (44.6%) and low-income (32.0%) subjects (p < 0.001). DG showed significantly lower snacking and dining out. There was significantly higher rate of DG who responded "none" in frequency of snack (27.10%) and dining out (29.50%) (p < 0.001). Also DG showed significantly lower rate of the subjects who ate with the family than NG. Also, DG showed significantly lower dietary guideline recognition level and practice than NG. Correlation between depression symptom and various factors showed that positive correlation with low snack intake and dining out frequencies. However, correlation was relatively weak. In conclusion, eating habits and recognition levels and practice of dietary guidelines of DG were significantly different from NG. DG showed significantly lower frequencies of snack, dining out, and eating with family.

Background and purpose:Δ133p53 can promote tumor cell growth, but the exact mechanism is not clear. This study was aimed to observe the expression and signiifcant of the p53 isoformsΔ133p53 and p53 gene downstream molecules MDM2 and cyclin G1 genes by 5-FU-MKN45 gastric cancer cell line model. Methods:Af-ter using different concentrations of 5-FU (50μg/mL, 100μg/mL) to human gastric cancer cell line MKN45, inhibition rate should be detected by MTT assay, the changes ofΔ133p53 mRNA, MDM2 mRNA and cyclin G1 mRNA express-ing were detected by reverse transcription-polymerase chain reaction (RT-PCR). Differences between these groups were analyzed by ANOVA, comparisons within groups were analyzed by t-test, bivariate correlation was analyzed by Pearson linear correlation. Results:MTT results showed that with the increased concentration of 5-FU and the extension of time, the cell inhibition rates increased gradually. The inhibition rates of 50μg/mL 5-FU were 41.10%, 54.79%and 68.48%, for culturing 24, 48 and 72 hours. There were statistically signiifcant differences between the groups(F=45.52, P=0.00). The inhibition rates of 100μg/mL 5-FU were 69.53%, 78.21%and 86.92%, for culturing 24, 48 and 72 hours. There were statistically signiifcant differences between the groups(F=85.58,P=0.00). The inhibition rates of 50 and 100μg/mL were 41.10%and 69.53%, for culturing 24 hours. There were statistically signiifcant differences between the groups(F=51.29, P=0.00). The inhibition rates of 50 and 100μg/mL were 54.79%and 78.21%, for culturing 48 hours. There were statistically signiifcant differences between the groups(F=51.29, P=0.00). The inhibition rates of 50 and 100μg/mL were 68.48%and 86.82%, for culturing 72 hours. There were statistically signiifcant differences between the groups(104.91, P=0.00). RT-PCR results showed that with the increase of the concentration of 5-FU, theΔ133p53 mRNA, MDM2 mRNA and cyclin G1 mRNA expression gradually declined in gastric cancer cell line MKN45 cells, and there were statistically signiifcant differences between the groups(F=738.532, 1 396.607, 2 785.56,P=0.00). Cor-relation analysis showed that the expressions ofΔ133p53 mRNA and MDM2 mRNA in gastric cancer were positively correlated (r=0.871, P=0.01), while the expression of cyclin G1 mRNA and p53 mRNA had no obvious relevance (P=0.13). Conclusion:In the 5-FU-MKN45 gastric cancer cell line model, anti-tumor pathway ofΔ133p53 isomers is related with MDM2 but was not related with cyclin G1.
