Objective To analyze the CT findings of lung cystic echinococcosis with infections, and to assess the value of CT examination. Methods The CT characters of 23 cases of pathologically proved lung cystic echinococcosis were analyzed and CT findings were compared with pathology. Results All 23 cases of lung cystic echinococcosis appeared as single cystic lesions. Fifteen cases appeared in the right lung, and the other 8 in the left. The lesions located in lower lobe were more than those in the upper lobe. According to the CT examination, it could be divided into two types: (1) simple lesion (7 cases) appeared as irregular solid mass with different size, crude edge, and lobulation, and with fiber shadows in the lung field around the lesions. In 6 cases, curvilinear or spotty calcification occurred in the lesions. (2) echinococcosis as a bag (16 cases) appeared as a mass with cystic changes in lung tissue with different size and off-center cystic cavity. The lesions took the form of ball or irregular shape. The edge was crude. Around the focus, prickle-like or patchy changes were detected. Ruptured lesions showed “water snake” or “flow ribbon” signs in 4 cases. In 7 cases, calcification occurred on the cystic wall or extended into the inside contents. Conclusion CT could accurately demonstrate the location, appearance, internal structure, and adjacent situation of the cystic echinococcosis, providing valuable information for correct diagnosis and treatment.

Objective To investigate the value of transvaginal color Doppler sonography (TVCDS) and magnetic resonance imaging (MRI) in diagnosis for myometrial invasion of eudometrial cancer before surgical operation, in comparison with pathological examinations. Methods TVCDS and MRI were undergone before surgical operation in 34 patients with endometrial cancer confirmed by biopsy to evaluate depth of its myometrial invasion, as compared to those with postoperative pathological examinations. Results Predictive accuracy for myometrial invasion by TVCDS was 85%, with sensitivity, specificity, positive predictive value and negative predictive value of 80%, 9/9, 100% and 9/14, respectively, and predictive accuracy by MRI was 68%, with sensitivity, specificity, positive predictive value and negative predictive value of 60%, 8/9, 15/16 and 8/18, respectively. Resistance index (RI) averaged 0.51 for flow signal to detect superfical myometrial invasion by color Doppler flow imaging (CDFI) and 0.43 for deep myometrial invasion. Conclusions TVCDS and MRI can be used before surgical operation to judge the depth of myometrial invasion for patients with endometrial cancer, particularly more suitable for its screening, which will be helpful to judge the depth of myometrial invasion incorporated with resistance index by color Doppler flow signal.

OBJECTIVE: To investigate the feasibility of introducing self-assembling peptides as protein drug carrier.METHODS: By using RAD16-Ⅰ as a model of self-assembling peptides,lysozyme as the model of protein drug,the property of self-assembling peptide solution containing protein to form hydrogel in-situ were characterized by rheology,and the property of protein release in vitro from self-assembling peptide in-situ hydrogel was studied.RESULTS: The self-assembling peptide RAD16-Ⅰ can form hydrogel with certain mechanical intensity rapidly after its solution contained protein being mixed with PBS.Proteins can release easily from RAD16-Ⅰ hydrogel in a sustained-release manner to some extent.About 80% of proteins can be released from the hydrogel within 8 hours and the cumulative protein release from 1.5% hydrogel was less than 90%.The bio-activity of lysozyme released from RAD16-Ⅰ hydrogel was well preserved as 98% to 115%.CONCLUSION: Self-assembling peptide can be employed as potential in-situ hydrogel carrier for protein drugs.

Objective To investigate the effect of hydrogen peroxide (H2O2) pretreatment on free mitochondrial cyto-chrome c (Cyt-c) release in mitochondrial levels, and reveal the mechanism of the ischemic preconditioning (IPC) on the ischemia reperfusion (IR) injury thereof. Methods The rat liver mitochondria was isolated and made free mitochondria. Free mitochondria were divided into 5 groups:control group (C) and different concentrations of Ca2+groups (12.5, 25, 50 and 100 μmol/L). The levels of Cyt-c and second mitochondria-defived activator of caspase (Smac) were detected after 10 min stimulation of free mitochondria. The free mitochondrial IPC reperfusion model was made and divided into seven groups:C group, IR group and different concentrations of H2O2 groups (2 μL H2O2 in 200 μL system respectively, final concentration of 1, 2, 5, 20 and 100 μmol/L respectively). 100 μmol/L Ca2+was used again on the simulation of IR group. The level of Cyt-c release was detected. The changes in the activity of cardiolipin were detected in IR group and H2O2 (1 and 2 μmol/L of final concentration) groups.Results Compared with C group, there were significantly higher levels of Cyt-c and Smac emission in 25, 50, and 100 μmol/L Ca2+groups (P<0.05). Compared with IR group, there was significantly decreased level of Cyt-c emission in H2O2 (1 and 2 μmol/L) groups (P < 0.05). The activity of cardiolipin was changed when reducing release of Cyt-c. Conclusion Cyt-c was bonded with cardiolipin more closely when the low concentration of H2O2 pretreatment in mitochondria. There was a lower level of Cyt-c emission in mitochondria after stimulation with high concentration of Ca 2+(100 μmol/L Ca2+). The blocking apoptotic pathway plays a key fact in the effect of IPC on IR injury.

Objective To investigate the relationship between single nucleotide polymorphism (SNP) of Fas ligand (FasL) and fulminant hepatitis B in Han Chinese. Methods HBV infected subjects were enrolled in this case-control study, including 233 cases of inactive HBsAg carrier, 68 patients with fulminant hepatitis B,100 cases of spontaneous hepatitis B clearance, 102 patients with hepatitis B virus (HBV) related cirrhosis and 112 patients with HBV related primary hepatocellular carcinoma. The blood samples and clinical data were collected. FasL-844T/C polymorphisms of enrolled subjects were examined by TaqMan real time fluorescent genotyping polymerase chain reaction (RT-PCR). A adjusted odds ratios (OR)and 95% confidence intervals (CI)were calculated using the Logistic regression model. Results After adjusting the factors of gender and age, binary Logistic regression analyses indicated that the genotype frequencies of FasL-844 CC,CT,TT in inactive HBsAg carriers were 50. 64% ,39. 91% and 9. 44% respectively, and those in cases of fulminant hepatitis B were 79. 41%, 17. 65% and 2. 94%, respectively. The analysis also revealed that FasL-844CC genotype in inactive HBsAg carriers was high risk factor of developing fulminant hepatitis B (OR =4. 729,95%CI:0. 510 - 21. 282,P = 0. 043), while there were no statistic significances in other cases (P>0. 05). Conclusion The inactive HBsAg carriers harboring FasL-844CC may have greater susceptibility to fulminant hepatitis B, which need arouse high attention.
