?ln recent years, the number of patients with diabetes increase rapidly. Diabetic retinopathy ( DR ) , one of the complications of diabetes, is also the important aspect of current and future prevention of blindness in our country. Now, more and more scholar have noticed the important role of immune inflammation in the pathogenesis of diabetic retinopathy. ln this article, we reviewed the role of interleukin-6 ( lL-6 ) in diabetic retinopathy.

Objective To investigate the expressions of transferrin receptor (TfR) mRNA, ferritin(Fn) mRNA and iron regulatory proteinl (IRP-1) mRNA in the placentas complicated with fetal iron deficiency(ID). Methods Depending on the cord SF,the subjects were divided to fetal ID group and fetal iron sufficient( IS) group. TfR mRNA, Fn mRNA and IRP - 1 mRNA in placentas were measured by RT - PCR. Results 1. The expression of TfR mRNA in ID group was 1.10 ? 0. 26, it was significantly higher than that in IS group (t=0.028 P0.05) ;4. TfR mRNA and Fn mRNA correlated with fetal IS respectively. Conclusion Fetal ID induces highly expressed TfR mRNA and lower level of Fn mRNA to furthest satisfy the iron need for fetus.

Objective To investigate the role of CTLA4-Ig and anti-CD40L monoclonal antibody in the acute rejection of pancreaticoduodenal transplantation model of rats.Methods Pancreaticoduo- denal transplantation model was established from the donor F344 rats to the Lewis recipients(diabetes models).The models were divided into 4 groups:groups A,B,C and D with 12 rats in each group. Two days after transplantation,recipients were injected intraperitoneally with saline,CTLA4-Ig(200?g),anti-CD40L monoclonal antibody(200?g),CTLA4-Ig(200?g)combined with anti-CD40L monoclonal antibody(200?g)respectively.On the day 1,4,7,10 after transplantation,the grafts were harvested for histopathological examination and RT-PCR to determine the levels of interleukin (IL)-2,interferon(IFN)-?,IL-4 and IL-10;The blood CD3~+,CD4~+and CD8~+ T cells were detected by flow cytometry.On the day 4 after transplantation,the CD4~+ CD25~+ T cells in the grafts were de- tected by flow cytometry.Results As compared with group A,the severity of the rejection of grafts in groups B,C and D were depressed;Down-regulation of IL-2 was observed in the groups B,C and D, and the levels in group D were lowest.Down-regulation of IFN-7 was detected in the groups B,C and D,but there was no significantly difference between groups D and B or groups D and C.Up-regulation of IL-4 was observed in the groups B and C,and the levels in group D were lower than in groups A,B and C.Up-regulation of IL-10 was observed in groups B and C,and there was significant difference between groups D and B or groups D and C.The CD3~+,CD4~+ and CD8~+ T cells in groups B,C and D were less,but more CID4~+ CD25~+ T ceils in transplanted pancreas were observed,more notably in group D than in group C.Conclusions Combined use of CTLA4-Ig and anti-CD40L monoclonal anti- body can remarkably diminish the severity of the rejection,which might be mediated by altering the balance in Th1/Th2 and increasing the number of CD4~+ CD25~+ regulatory T cells.Co-stimulation blockade with CTLA4-Ig and anti-CD40L monoclonal antibody induction seems to be an attractive strategy to control allograft rejection.

Objective To evaluate the effect of 36-neuro-motorial examination on early diagnosis of children with cerebral palsy within 1 year-old.Methods36-neuro-motorial examination was analysed in 210 children with cerebral palsy from 2 to 12 months. Results4-29 items reflecting the abnormity of reflex, muscle tone, posture and motion were observeed in patients with cerebral palsy.If these abnormities were laid according as frequency among 2-6 months,reflex abnormities are knee tendon reflex, palmar grasp reflex,Babinski sign,asymmetrical tonic neck reflex,ankle clonus,sitting equilibrium reflex,stepping reflex,crossed extension reflex,tonic labyrinthine reflex,trunk incurvation reflex,Moro reflex; posture abnormities are head to back≥15°,from supine to the side position, axillar suspension reflex,posterior neck fovea≥1cm in the supine position,landau reflex,Vojta reflex,traction reflex,tonic torticollis,abnormal spontaneous posture;muscle tone abnormities are foot dorsiflexion angle,scarf sign,tonic palmar grasp,to up the foot heel≥30° in the stand position,thumb decussation to the palm,poples angle,adductor angle,heel-ear angle; others are head cycle≤-2s, squint, active movement attenuation or abnormity, auditory abnormity, visual abnormity, ophthalmodonesis, epilepsy.Conclusions 36-neuro-motorial examination is effective for early diagnosis of cerebral palsy within 1 year.

Objective To study the expression and function relations of the p63 in ovarian serous carcinoma,and compare them with normal ovary tissue.Methods RT-PCR,in situ hybridization and im- munohistochemistry were used to detect the expression of the p63 in ovarian serous carcinoma,ovarian bor- derline serous tumors,ovarian benign serous tumors and normal ovary tissues.Results All samples ex- pressed p63 mRNA through RT-PCR and immunohistochemistry,while the levels of expression in ovarian tu- mors was higher than that of normal ovary.p63 in human borderline and malignant ovarian tumors was higher than that in human benign ovarian tumors with significant difference,which suggested p63 may play great roles in the origin and progression of ovarian tumors.The result of in situ hybridization showed that positive expression rate of p63 mRNA in ovarian cancer (92.1%) was significantly higher than that in normal ovary(0) or LWP ovarian cancer(50.0%).Conclusion Expression of p63 plays an important role in the development of varian carcinoma,and along with the difference of histological stage and clinico-pathological stage,the ex- pression of p63 gene and protein level were different.

Organic solvent tolerant microorganism(OSTM) is a novel extremophile and it hasn't been systematically studied until 1980s.Relying on certain mechanisms,the OSTM is able to effectively de-fend and decrease the toxicity from organic solvents,which enable the OSTM to be potentially applied in the industrial fields such as whole-cell catalysis and environmental treatment,etc.The comprehen-sively understanding of the mechanisms involved in organic solvent tolerance of OSTM could be com-bined with genetic engineering in order to modify and optimize the various specifications of OSTM,and further broaden its application in other industrial areas.Latest studies on the tolerant mechanisms of OSTM,in this paper,will be reviewed from four aspects such as vesicle exocytosis and changes of phos-pholipid composition in membrane,etc.Besides,the application of OSTM in whole-cell catalysis and other fields will be introduced.

Objective To evaluate the effects of 131 adrenoceptor anfisense on blood pressure and?1 adrenoceptor mRNA and protein levels in 2 kidney 1 clip(2K1C)rats.Method 2KIC hypertensive rots were produced by clipping renal artery of SD rats.Liposome/AS-ODNs 2.0 were tested intravenously in rats with 2KIC hypertension.Animals were divided into 5 groups(n=18 in each group):?1-AS-ODN group,?1-IN-ODN group,2K1C group,Sham group and SD group.Blood pressure was measured by tail-cuff method,the levels of myocardial?adreneceptor mRNA and protein were tested by RT-PCR and binding assay.Results On the basis of the magnitude and duration of hypotension,?1-AS-ODN decreased blood pressure by 39 mmHg at the most for 4 weeks.Compared with the 2KIC group,?1-AS-ODN did not significantly change the levels of myocardial?1 adrenoceptor mRNA but significantly decreased the levels of myocardial?1 adrenoceptor protein at 2,7,30 days (P
