?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 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 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.

OBJECTIVETo study the population structure and ecological distribution of the rhizosperic microorganisms of Angelica sinensis.
METHODThe isolation, culture and identification of microorganisms were studied by the biological methods, and the achieved data were analyzed by the statistical methods for analysis of species diversity.
RESULTWith the growing stages of A. sinensis from Min county of Gansu province, Heqing of Yunnan province and Baoxing of Sichuan province, the quantity of rhizosperic microorganisms increased; and it had reduced since October. In the area of Min county Gansu province, the number ratio of bacteria and fungi was higher than that in the other two areas. In addition, the population diversity and dynamic change were different in three areas. In the area of Min county Gansu province, the number of dominant microbial populations and the population diversities of bacteria, actinomyces and fungi in the rhizosphere were greater than those in the other two areas.
CONCLUSIONThe microecological system and microbial population structure in the rhizosphere of Min county Gansu province were stable. And it was suitable for the growth of A. sinensis in this area.

OBJECTIVETo compare the difference in the efficacy on low back pain of cold-damp pattern between electric-thermal Bian-stone therapy and moxibustion box therapy.
METHODSForty-one cases of low back pain of cold-damp pattern were randomized into an electric-thermal Bian-stone therapy group (group A, 26 cases) and a box moxibustion therapy group (group B, 15 cases). In the group A, the electric-thermal Bian-stone was placed over Shenshu (BL 23) and Weizhong (BL 40). The temperature of stone was adjusted in accordance with patient's comfort. In the group B, moxibustion box was used over Shenshu (BL 23) and Weizhong (BL 40). The treatment was given once every day or every two days. Ten treatments made one session. The symptom and physical signs score of low back pain and the score of cold-damp syndrome were observed before and after treatment in the patients.
RESULTSThe symptom and physical signs score of low back pain and the score of cold-damp syndrome were all improved in the two groups (all P < 0.01). The changing rate of symptom and physical signs and syndrome were (37.04 +/- 32.68)% and (22.85 +/- 29.95)% in the group A, and were (47.29 +/- 22.08)% and (23.89 +/- 22.53)% in the group B, respectively, without significant difference in comparison between the two groups (all P > 0.05).
CONCLUSIONThe efficacy on low back pain of cold-damp pattern treated with the electric-thermal Bian-stone therapy is similar to that of moxibustion box therapy. This therapy is characterized as more convenient, safer operation and less pollution.

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

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.
