To investigate the induction of apoptosis of mouse colonic adenocarcinoma CT26 cells by recombinant Clostridium difficile toxin B (rTcdB), CT26 cells were exposed to different concentrations of rTcd B. Inhibition of cell proliferation was measured by MTT assay. The activation of Caspase 3 was measured by colorimetric method. Cell morphological analysis and flow cytometry were performed to confirm cell apoptosis. rTcd B inhibited the proliferation of CT26 cells in a timeand dose-dependent manner. Caspase 3 activity in CT26 cells was elevated remarkably after rTcd B exposure for 6 h, 12 h, 18 h or 24 h, as compared with the control group. Morphological changes were observed by fluorescence microscopy. The exposure of rTcd B to CT26 cells induced a timeand dose-dependent apoptotic cell death as determined by flow cytometry analysis. The results showed that recombinant Clostridium difficile toxin B induced apoptosis of CT26 cells.

The desired DNA product of KGPcd and KGP-hag was obtained from the total DNA of Porphyromonas gingivalis by PCR with two pairs of gene specific primers. The segment of KGPcd and KGP-hag (about 1.5kb and 1.6kb) was inserted into pGEM-T easy Vector. The double-stranded DNA of the postitive clone was analyzed by restriction endonuclease mapping and DNA sequenceing. The sequences of KGPcd and KGP-hag were consistent with those of the references appeared. The proteins of KGPcd and KGP-hag will be obtained for further study.

AIM: To explore correlation,consistency and comfort between traditional tear film examination methods and Oculus Keratograph.METHODS: A retrospective study.Totally 101 cases (101 eyes) were diagnosed myopia and then accepted LASEK (laser epithelial keratomileusis).Non-invasive tear film break-up time(NIBUT),lower tear meniscus height(LTMH) were measured with Oculus Keratograph,fluorescein tear film break-up time(fl-BUT) and Schimer Ⅰ test (SⅠt) were performed on all cases.The correlations analysis between NIBUT and fl-BUT,LTMH and SⅠt were performed by Spearman rank correlation,consistency check between NIBUT and fl-BUT by Bland-Altman analysis.Visual analogue scale(VAS) was applied on evaluating the comfort of two kinds of examination methods.RESULTS: LTMH and SⅠt showed positive correlation (rs=0.346,P=0.001).NIBUT and fl-BUT showed positive correlation (rs=0.393,P=0.001),95% consistency limits range-9.62 to 14.18 in Bland-Altman Figure.There was significant difference between VAS of NIBUT and VAS of fl-BUT(z=-2.324,P=0.020).There was significant difference between VAS of LTMH and VAS of SⅠt (z=-8.845,P=0.001).CONCLUSION: Oculus Keratograph can objectively measure NIBUT and LTMH,and was more comfortable than traditional tear film examination methods.It can effectively assess tear film function before corneal refractive surgery.

Objective To explore the impact factors for post-thaw embryo survival rate and clinical pregnancy rate in frozen-thawed embryo transfer program. Methods The clinical data of 573 cycles of frozen-thawed embryo transfers were retrospectively analysed. Groups were divided according to the pre-freeze embryo quality, pre-freeze embryonic developmental stage, frozen-thawed embryo quality and cryopreservation technique, respectively, and post-thaw embryo survival rates and/or clinical pregnancy rates were compared among groups. Results The clinical pregnancy rate of high quality pre-freeze embryo was significantly higher than that of low quality pre-freeze embryo (31.8% vs 20.0%) (P< 0.05). There was no significant difference in the post-thaw survival rates and clinical pregnancy rates between embryos frozen at day 2 of ferrtilization and those frozen at day 3 of ferrtilization(79. 1% vs 82.9% and 25.5% vs 31.2%, respectively) (P>0.05). The clinical pregnancy rates of the transfer cycles only with fully intact embryos and with mixed embryos were significantly higher than that only with partially damaged embryos(36.7% vs 24.1% and 29.2% vs 24.1%, respectively)(P<0.05). The post-thaw survival rate and post-thaw high-quality embryo rate were significantly higher in those processed with modified cryopreservation technique than in those processed with original cryopreservation technique (82.0% vs 66.3% and 50.0% vs 27.5%, respectively)(P<0.05). Conclusion Pre-freeze embryo quality, post-thaw embryo survival rate and post-thaw embryo quality have a positive correlation to subsequent clinical pregnancy rate. Favorable cryopreservation technique may ensure the success of post-thaw embryo recovery and transfer.

OBJECTIVETo investigate the etiology of 1977 patients from northern China with acute (ALF), sub-acute (SALF) or acute-on-chronic liver (ACLF) failures.

METHODThe age, gender, etiology, pathogenesis, and prognosis of the 1977 patients with liver failures were retrospectively analyzed.

RESULTSOf the 1977 cases, the three most common causes of ALF were HEV (33.96%) or HBV (13.21%) infections or those caused by medicines (9.43%). The three predominant causes of SALF were medicines (31.53%), HEV (16.22%) or HBV (9.91%) infections, but those of the ACLF were HBV (90.29%) infection, alcoholic hepatopathy (2.65%), and HBV super infected with HEV (2.26%) infections. 90.09% (1781) patients were infected by hepatotropic viruses. Of these 1781 patients, the most common cause of their liver failures was HBV infection (92.93%). In these HBV infected patients, 77.10% were from 26 to 55 years old. From 2005 to 2007, there were 39 patients with alcoholic liver failure. In the past two years, there were 23 patients with drug induced liver failure. The improvement rate of the 1977 patients after their treatments was 35.56%. The improvement rate of HEV infected liver failure was higher than drug induced liver failure (P less than 0.05); no statistical significance was found between other groups (P more than 0.05).

CONCLUSIONDifferent types of liver failure have different predominant causes. HBV infection is the most common cause in our 1977 patients. In the past two years, the number of drug induced liver failures and alcoholic liver failures have been increasing.

Objective To observe the clinical efficacy of SHAO's five-needle therapy in treating active ulcerative colitis. Method By following a randomized controlled design, 57 patients with active ulcerative colitis were divided into a lung-intestine simultaneous treatment group of 28 cases and an intestine treatment group of 29 cases. The lung-intestine simultaneous treatment group was intervened by SHAO's five-needle therapy plus medications including oral administration of mesalazine, sulfasalazine suppositories via rectal insertion and Ge Gen Qin Lian decoction via enema; the intestine treatment group was intervened by medications. The two groups were both treated successively for4 weeks. The Sutherland Disease Activity Index (Sutherland DAI) was observed in the two groups and the release rate was also assessed; the main clinical symptom and sign scores of the two groups were recorded before and after treatment. Result The Sutherland DAI score dropped after treatment in both groups (P<0.05), and the between-group difference was statistically significant (P<0.05); the scores of abdominal pain, diarrhea and stool mixed with pus and blood declined after treatment in both groups (P<0.05), and the between-group differences were statistically significant (P<0.05); the lung-intestine simultaneous treatment group was superior to the intestine treatment group comparing plus medications the therapeutic efficacy regarding the symptoms and signs (P<0.05). Conclusion SHAO's five-needle therapy can rapidly release the clinical symptoms and body signs of active ulcerative colitis and enhance the clinical efficacy.
