Survivin is a protein that inhibits apoptosis and regulates cell division.The cDNA sequence of survivin was amplified by RT-PCR and sub-cloned into the prokaryotic expression vector pET-21b(+),followed by transformation into E.coli strain BL21(DE3) and induction with IPTG.The recombinant survivin protein fusing with 6?His tag was expressed in E.coli in the form of inclusion body at the expression level over 60% of the total cell protein.Results of Western blotting showed that recombinant survivin reacted specifically with anti-human survivin antibody.After gel filtration,the recombinant protein reached the purity over 95%,which facilitate the study of diagnosing and inhibitor agents targeting survivin.

AIM: To study effects of hyperbaric oxygen (HBO) and cyclosporin A (CsA) on the contents of active oxygens and nitric oxide (NO) in spleens of skin transplanted mice. METHODS: The donor mice BALB/C and receptor mice Cs7BL/6 were tested for skin transplantation. The HBO group mice were,treated with 99.2 % oxygen under 0.25 MPa for 1.5 hours, while CsA group mice were treated with CsA 0.5 rmg· kg- t· d- 1 by abdomen injection. After 14 days, the spleen were extracted the contents of malondialdehyde (MDA) and NO and the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH - PX), catalase (CAT) and NO synthases (NOS) were determined. RESULTS: (1) Compared with the control group, the transplantation group, HBO group and CsA group have markedly increased the content of MDA and the activities of GSH - PX and CAT; Compared with the transplantation group, the CsA group have markedly increased activity of SOD and reduced activities of GSH - PX and CAT; the HBO group have markedly reduced the activity of GSH - PX and increased the activities of CAT and SOD (P < 0.01 ). (2) Compared with the control group, the transplantation group have markedly increased the content of NO and the activity of NOS; Compared with the transplantation group, the HBO group have markedly increased the activity of NOS and reduced the content of NO ( P < 0.01 ); The content of NO and the activity of NOS in CsA group was not changed significantly. CONCLUSION: In the lymphocytes of the transplantation group, the peroxidation is intensified, and the content of NO and the activity of NOS increased. HBO and CsA may activate the systems of oxidation/antioxidation and NO/NOS in spleen, which may be related to their mechanism of inhibition rejection.

Objective: To evaluate the immunomodulatory activity of the roots and rhizomes in Rosa laevigata (Rosa Laevigata Radix) in Guangxi, Yunnan, and Guizhou provinces. Methods: The effects of cellular immunity, humoral inmunity, and non-specific immunity were investigated on delayed-type hypersensitivity, serum hemolysin antibody, and carbon clearance of mice, respectively. Results: Rosa Laevigata Radix could inhibit the delayed-type hypersensitivity and serum hemolysin antibody in mice, but had no effect on carbon clearance. All the roots and rhizomes of R. laevigata from different habitats had no statistically significant difference on immunomodulatory activity. Conclusion: The roots and rhizomes of R. laevigata from different habitats have the similar immunosuppressive activity.

AIM: To evaluate cell proliferation, apoptosis and migration of human retinal pigment epithelial cells ( RPE) when co - cultured with human marrow mesenchymal stem cells ( hMSCs ) in condition of hypoxia and hyperglycemia so as to explore possible mechanisms of diabetes aggravating choroidal neovascularization ( CNV) preliminarily.
METHODS:Both hMSCs and RPE cells were co-cultured in a transwell system. The experiment was divided into four groups: 21% O2 with 5. 56mmol/L glucose ( control group, A ), 21% O2 with 30mmol/L glucose ( hyperglycemia and normoxia group, B ) , 5% O2 with 5.56mmol/L glucose ( normoglycemia and hypoxia group, C ) and 5% O2 with 30mmol/L glucose ( hyperglycemia and hypoxia group, D) . Cell Counting Kit-8 (CCK-8) was used to detect the proliferation of RPE cells in each group at 12, 24 and 48h respectively. Flow cytometry was performed to observe apoptosis of RPE cells at 24h. Additionally, we assessed migration
capabilities of RPE via transwell assay under the condition of hyperglycemia and hypoxia by co-culturing of hMSCs.RESULTS:In this co-culturing system, at 12, 24 and 48h, group B (1. 61±0. 41, 1. 80±0. 34;1. 91±0. 35), C (1.34±0. 46, 1. 94±0. 40, 2. 14±0. 41) and D (1. 98±0. 47, 2.26±0.42, 2. 55±0. 40) showed significantly higher proliferation rate than group A (0. 92±0. 45, 1. 27±0. 32, 1.59±0. 41, P<0. 05). The migration capabilities of RPE in group B (149. 5±9. 19), C (140±9. 90) and D (170. 5±7. 78) increased dramatically compared with group A ( 114. 5±7.78, P<0.05) at 24h, whereas there was no significant difference of apoptosis ratio among four groups (P>0. 05).
CONCLUSION:By coexistence with hMSCs, the synergy of hyperglycemia and hypoxia can improve migration and proliferation of RPE cells, and have no effect on apoptosis of RPE cells within short period.

OBJECTIVETo establish discriminant functions of diarrhea-predominant irritable bowel syndrome (IBS-D) by studying it from quantitative diagnosis angle, hoping to reduce interference of subjective factors in diagnosing and differentially diagnosing Chinese medical syndromes of IBS-D.

METHODSA Chinese medical clinical epidemiological survey was carried out in 439 IBS-D patients using Clinical Information Collection Table of IBS. Initial syndromes were obtained by cluster analysis. They were analyzed using step-by-step discrimination by taking information of four Chinese medical diagnostic methods and serum brain-gut peptides (BGP) as variables.

RESULTSClustering results were Gan stagnation Pi deficiency syndrome (GSPDS), Pi-Wei weakness syndrome (PWWS), Gan stagnation qi stasis syndrome (GSQSS), Pi-Shen yang deficiency syndrome (PSYDS), Pi-Wei damp-heat syndrome (PWDHS), cold-damp disturbing Pi syndrome (CDDPS). Of them, GSPDS was mostly often seen with effective percentage of 34. 2%, while CDDPS was the least often seen with effective percentage of 5.5%. A total of 5 discriminant functions for GSPDS, PWWS, GSQSS, PSYDS, and PWDHS were obtained by step-by-step dis- crimination method. The retrospective misjudgment rate was 4.1% (16/390), while the cross-validation misjudgment rate was 15.4% (60/390).

CONCLUSIONThe establishment of discriminant functions is of value in objectively diagnosing and differentially diagnosing Chinese medical syndromes of IBS-D.

OBJECTIVETo study the blood pressure (BP) changes in the liver transplant recipients.

METHODSA total of 206 patients without preoperation hypertension received liver transplantation in our hospital from February 2001 to July 2005. The BP level and serum immunosuppressant concentration at preoperation and various time points post operation were determined.

RESULTSCompared with the preoperation, the average systolic and diastolic pressure was significantly increased at the 2 week, 1, 2, 4 and 6 months post operation. The mobility of hypertension increased significantly after liver transplantation, with the highest mobility (46.49%) at the 1st month post operation. There was no linear correlation between the immunosuppressant (FK506) concentration and the BP level at any time point.

CONCLUSIONThere was a high hypertension incidence after liver transplantation. Although the use of immunosuppressive drugs accompanied with the BP increase, there was no linear correlation between the immunosuppressant concentration and the BP level post operation.
