Objective　 To investigate the relationship between of serum bilirubin concentrations and risk of coronary heart drsease (CHD). Methods　 Serum bilirubin concentrations were determined in 12 cases with acute myocardial infarction(AMI)、37 cases with unstable angina pectoris (UAP) and 30 cases with UAP with arrhythmia. Results　 The serum total bilirubin(TB)、direct bilirubin(DB)、indirect bilirubin(IB) concentrations were lower in the three study groups of CHD than in the controls. There was significant difference between the patients with CHD and the controls. However, there was no significant difference among the three study groups of CHD. Conclusion　 Serum bilirubin concentrations was inversely and statistically significantly related to risk of CHD.

The internal limiting membrane (ILM),composed of collagen fibers,glycosaminoglycans,laminin and fibronectin,is the basement membrane of the retinal Müller glia cells and serves as an interface between the vitreous and retina.The ILM is the structural interface between the vitreous and retina.ILM removal ensures separation of the posterior hyaloid from the macular surface,which can relieve macular traction and prevent postoperative epiretinal membrane formation.Thus,vitrectomy with ILM peeling has become an increasingly utilized and vital component in surgical intervention for various vitreoretinal disorders.However,many recent studies showed that ILM peeling is a procedure that can cause immediate traumatic effects and progressive modification on the underlying inner retinal layers.There were some surgical strategy (fovea-sparing ILM peeling or inverted internal limiting membrane flap technique,or Abrasion Technique).But some controversies exist,such as when ILM peeling is necessary,which adjuvant to use to perform the procedure,and what is the best technique to peel the ILM.A full assessment ILM structure and function and related factors of surgery is helpful to predict the anatomical and functional prognosis.

Mucosa-associated lymphoid tissue (MALT} lymphoma is a low grade B-cell lymphoma arising from MALT of extra-nodal. A link of Helicobacter pylori (HP) infection with gastric MALT lymphoma was confirmed in the early years. Currently, growing evidence indicates that development of non-gastric MALT lymphoma is also associated with infections by microbial pathogens. t(l1;18)(q21;q21)、t(l;14)(p22;q32) and t (14;18)(q32;q21) are specifically associated with MALT lymphoma, which occur at variable incidences in MALT lymphoma of different sites. The oncogenic activity of these three chromosome translocations is linked by antigen receptor-mediated NF-κB activation.In addition, a number of novel genetic abnormalities have been recently identified in MALT lymphoma. The findings of these microbial pathogens and molecular genetics would be helpful in better understanding the pathogenesis of MALT lymphoma and also useful for the diagnosis at early stage and proper treatments of MALT lymphoma.

AIM:To study the effects of different duration of sleep deprivation (SD) on neurogranin (Ng),protein kinase C (PKC) and Ca2+-calmodulin dependent protein kinase II (CaMK II) mRNA expressions in hippocampus and forebrain of rats. METHODS:Male Wistar rats were divided into three groups:24 h,48 h and 72 h experimental groups. Each group was divided into sleep deprivation group (SD group) and control group (C group). SD model was established by sleep deprivation box. One step methods by Trizol was used to extract hippocampus and forebrain neuronal total RNA. The changes of Ng,PKC and CaMK II mRNA expressions were detected by SYBRA green I RT-PCR. RESULTS:(1) The expression of Ng mRNA in hippocampus of SD group was significantly lower than that in C group after 24 h,48 h and 72 h SD (P

OBJECTIVE: To investigate the antagonistic effect of Salvia miltiorrhiza on cyclosporine A (CsA)-induced chronic nephrotoxicity. METHODS: 54 patients underwent renal transplantation were divided into 3 groups according to dosage of salvia miltiorrhiza: CsA+high-dose of salvia miltiorrhiza group, CsA+loe-dose of salvia miltiorrhiza group (trial group) and CsA control group (control group). Plasma concentration of CsA, serum creatinine (Scr), blood urea nitrogen (Bun), 24 h urines and 24 h urinary protein were recorded. The parameters of morphology and hemodynamics were compared among 3 groups. The differences of index among 3 groups were analyzed statistically. RESULTS: The level of Scr, Bun and 24 h urinary protein in CsA+high-dose of salvia miltiorrhiza group were decreased significantly while 24 h urines was increased, compared with other 2 groups. There was significant difference among 3 groups (P0.05). The intrarenal blood flow and renal arterial resistance index were increased significantly in CsA+high-dose of salvia miltiorrhiza group. CONCLUSION: High-dose of salvia miltiorrhiza combined with CsA can reduce the CsA-induced nephrotoxicity perfently.

thyroid cancer(TC-1 ),a nuclear protein coded by TC-1,regulates the cell cycle,participates transcription and translation,and is correlated with the proliferation of normal and cancer cells.TC-1 participates in the Wnt/beta-catenin signaling pathway which can promote the up-regulation of proto-oncogene.Hence it plays an important role in the malignant transformation and development of the tumors,such as thyroid cancer,gastric cancer and breast cancer.Therefore,as a potential tumor-associated protein,it's likely to be used for fundamental research and gene targeting therapy.

Epithelial cell adhesion molecules (EpCAMs) play an important role in the process of gene expression and regulation by combining with nuclear receptor.Aberrant expression of EpCAMs has been detected in different types of cancers,such as breast cancer,lung cancer,gastric cancer,and etc.The research of EpCAMs in circulating tumor cells enrichment,tumor pathogenesis and prognosis will be conducive to achieve new breakthroughs in cancer targeted therapy.

To investigate the changes in serum enzymes (ALP、LDH、CK) in dogs suffered from gunshot wounds in limbs in hot and humid environment, 12 dogs were divided into two groups randomly: hot and humid environment (HHE) group and normal environment (NE) group. The contents of ALP, LDH and CK in peripheral blood were assayed at 0h, 2h, 4h, 6h, 8h, 12h and 24h postinjury. The results showed that the contents of serum enzymes tended to rise after gunshot injuries, especially CK. The changes in the contents of serum enzymes in HHE group appeared earlier and more obviously than those in NE group. In conclusion, the contents of serum enzymes coincided with the severity of local tissue damage, and change in the content of CK was more sensitive after tissue injury. The results suggested that hot and humid environment would aggravate systemic reactions and tissue damage after gunshot injuries.

To explore the prevention of deterioration of damaged tissue in gunshot wounds in limbs in hot and humid environment, 18 healthy male mongrel dogs were divided into three groups randomly: hot and humid environment (HHE) group, normal environment (NE) group, and heat acclimatization (HA) group. Histopathological changes and bacterial quantity in wound tracks were observed at postinjury o, 1, 4, 6, 8, 12 and 24h. It was found that the swelling of limbs and local pathological changes in injured tissues of HA group were significantly less serious and appeared later than those of HHE group, but severer and appeared earlier than those of NA group. The period that the bacterial quantity reaching the critical point of infection was 8h in HHE group, 12h in HA group and NE group. It is concluded that the pathological changes in gunshot injury in dogs inflicted in hot and humid environment could be lessened by exercise with heat acclimatization.
