Objective Through gene reconstruction we generated pcDNA 3-survivin-mutant(Cys84Ala)plasmid, then the plasmid DNA was further transfected into gastric carcinoma cells by liposomal delivery. The effects of mutant survivin on cytokinetics of the gastric carcinoma cells were obversed. Methods By using immunohistochemical staining, the expression of survivin was detected in the gastric cancer tissues, and apoptosis was detected by flow cytometry. The PARP and cytochrome C expressions were determined by Western blot, the mitotic catastrophe was determined by immunofluorescence. Results Inhibition of survivin by mutant survivin cDNA could induce apoptosis, increase caspase-3 activity, cleave PARP and promote cytochrome C release in gastric cancer cells. Inhibition of survivin also caused mitotic catastrophe in gastric cancer cells. Conclusion Inhibition of survivin may induce apoptosis and mitotic catastrophe in gastric cancer. Survivin targeting gastric cancer therapy might be of potential benefit in the future.

Objective To assess CT, MR manifestations and diagnostic value in hepatic tuberculosis. Methods CT findings in 12 cases and MR findings in 4 cases with hepatic tuberculosis proved by surgery or biopsy were retrospectively analyzed. Results (1) CT findings: one case of serohepatic type of hepatic tuberculosis was multiple nodular lesions in the subcapsule of liver. Parenchymal type were in 10 cases, including multiple,miliary, micronodular and low density lesions with miliary calcifications in 2 cases, singular, low density mass with multiple flecked calcifications in 3 cases, multiple cystic lesions in 1 case, multiple micronodular and low density lesions fusing into multiloculated cystic mass or “cluster” sign in 3 cases, and singular, macronodular and low density lesion with multiple miliary calcifications in 1 case. One case of tuberculous cholangitis showed marked dilated intrahepatic duct with multiple flecked calcifications in the porta hepatis. (2) MR findings in 4 cases were hypointense on both T 1WI and T 2WI in one case, hypointense on T 1WI and hyperintense on T 2WI in 3 cases. Enhanced MR in 3 cases showed slightly peripheral enhancement or with multilocular enhancement. Conclusions Various types of hepatic tuberculosis had their different imaging findings. The typical CT and MR findings could suggest the diagnosis.

Acetaminophen(AAP)-induced hepatic injury is one of the common causes of drug-induced hepatic injury.Up to date,the mechanisms of AAP-induced hepatic injury are still incompletely understood.Recent advances suggest that reactive metabolite formation,glutathione depletion,alkylation of proteins,especially mitochondrial proteins and peroxynitrite formation are critical initiating events for the toxicity.This review will focus on more recent advances in mitochondrial dysfunction after AAP overdose.Additional,oxidative stress and inflammatory mediators are also important for the overall outcome.

Objective To assess the clinical value of low-frequency mini - probe sonography ( LFMPS) in preoperative localization of pancreatic endocrine tumors comparing with other imaging methods. Methods Twenty one cases with suspected pancreatic endocrine tumors were enrolled from June 2000 to June 2002, we compared the diagnostic results of LFMPS, transcutaneous ultrasonography ( US) , helico-computed tomography ( HCT) and magnetic resonance imaging (MRI) with surgical localization and histopathological results by using Fujinon 7. 5 MHz miniature probe and SP-701 ultrasonic system. Results Sixteen pancreatic insulinomas and 1 extra pancreatic VIPoma (vesoactive intestinal polypeptide tumor) were confirmed by surgery and histopathological examination in 17 of the 21 patients, and the rest 4 patients didn't receive surgical procedure because of the negative results in all imaging studies. Among pancreatic lesions, they located on head, body and tail in 9, 3 and 4 cases respectively; the average diameter of all 17 lesions was 2. 02cm. LFMPS correctly localized the tumor in 14 of 17 patients (82. 4% ) while CT in 15 of 17 patients (88. 2% ) , MRI in 12 of 17 patients (70. 6% ) and US in 9 of 17 patients (52. 9% ). Besides, the diagnostic accuracy of LFMPS in detection of small size (

Traditional Chinese medicine (TCM) has its own system of diagnosis and treatment theory, and its methods for evaluating clinical efficacy are different from those of Western medicine. Applying evaluation techniques and methods that are used in Western medicine mechanically to TCM will not work. So building evaluation techniques, which adhere to regulations and characteristics of TCM, is necessary and imperative. As the quality of life and patient-reported outcome instruments were brought into practice and developed, clinical evaluation ideas and methods for TCM are provided with an opportunity for development. This article puts forward the concept of subjective complex outcomes (SCOs), which constitutes subjective feelings gained from the patient, doctor and caregiver, different from laboratory parameters. SCOs provide a multidimensional and complex health-related quality of life (HRQL) assessment and focus on the source of assessment information of diseases. This article also introduces a case study building SCO methods of TCM treatment for chronic obstructive pulmonary diseases, in order to promote discussion and provide a platform for future research.
