Chinese Journal of Immunology 2001;0(10):-
Objective:To explore whether the mRNA expression of TNFRSF12 in peripheral blood leukocytes of SLE patients is abnormal and to determine whether the TNFRSF12 gene is susceptibility gene to SLE.Methods:The level of mRNA expression of TNFRSF12 in peripheral blood leukocytes was detected by TaqMan one-step RT-PCR method.Results:The mRNA expression pattern in SLE patients is different to that of normal control.The mRNA in SLE consists of 2 types of isoforms of TNFRSF12,encoding membrane bound glycoprotein and potentially secreted molecules respectively,whereas only the latter in normal control.After PHA treatment,the mRNA expression pattern in normal control becomes the same as that of SLE patients.Overall TNFRSF12 mRNA expression was significantly decreased in active SLE group and significantly increased in lupus nephritis group.Conclusion:The results indicated that TNFRSF12 may play a role in the pathogenesis of SLE and was susceptibility gene to SLE.

Objective To investigate the efifcacy of thalidomide combined with VAD in treatment of elderly multiple myeloma(MM). Methods 76 cases of elderly MM were randomly divided into two groups, control group (n=38) were treated with VAD alone while the observation group (n=38) were treated with thalidomide and VAD. Clinical efifcacy and adverse reactions in two groups were compared. Results The total effective rate in observation group was 84.21%, which was signiifcantly higher than 55.26%in control group (P<0.05). After treatment, the M protein, myeloma cells andβ2-microglobulin in observation group were (20.77±4.15)×10-2μg/mL, (12.84±2.85)×10-2μg/mL and (2.48±0.53)μg/mL, which were signiifcantly lower than before treatment and control group(P<0.05). Hemoglobin in observation group was (108.83±5.81) g/L, which was signiifcantly higher than before treatment and control group(P<0.05). The adverse reactions were nausea, vomiting, drowsiness, constipation, infection and rash and so on in two groups after treatment, and there was no signiifcant difference between two groups. Conclusion Thalidomide combined with VAD regimen has a better effect in treatment of elderly multiple myeloma than single VAD, has less adverse reactions and well tolerated.

Objective · To observe effect of 17β estrodial (17β E2) with different concentrations on C type natriuretic peptide (CNP), insulin like growth factor 1 (IGF1), and natriuretic peptide receptor B (NPR-B) expression and proliferation of growth plate chondrocytes of rats in vitro. Methods · Eight Wistar rats were sacrificed and their epiphyseal cartilages of the upper tibias were separated to obtain chondrocytes on the 14th day after birth. Then chondrocytes were cultured with 17β E2 in different concentrations (10-4、10-6、10-8、10-10 and 10-12 mol/L) for 48 h, while control group was cultured without 17β E2. CCK8 method, ELISA and qRT-PCR were used to analyze the proliferation of chondrocytes, the levels of CNP and IGF1 in culture medium and mRNA levels of CNP, NPR-B and IGF1, respectively. Results · 17β E2 in different concentrations affected the proliferation of growth plate chondrocytes significantly. When the concentration of 17β E2 was 10-8 mol/L, it had the strongest effect on the cell proliferation. When the concentration increased to 10-4 mol/L, the proliferation of chondrocytes was inhibited. With the increasement of 17β E2 concentration, the levels of CNP in the culture medium and the mRNA levels of CNP in the chondrocytes were significantly different. The highest levels of CNP protein and mRNA both appeared in 10-8 mol/L group, while the lowest levels both appeared in 10-4 mol/L group. IGF1 and its mRNA also reached the highest levels in 10-8 mol/L group,but the lowest concentration and mRNA level were in 10-10 mol/L group and 10-12 mol/L, respectively. Both CNP mRNA and protein levels were positive correlated with the proliferation of chondrocytes (P=0.000). Nevertheless, there was no significant correlation between the proliferation of chondrocytes and IGF1 mRNA or protein levels (P>0.05). Conclusion · 17β E2 modulates proliferation of rat growth plate chondrocytes in a dose-effect manner. It enhances proliferation at relatively low concentrations (10-10-10-8 mol/L) and inhibits proliferation at high concentration. This effect is positively related to CNP expression in chondrocytes.

Iron uptake mechanism of Vibrio alginolyticus was primarily investigated. V.alginolyticus could survive in the medium with high-concentration iron chelator. The strain of V. alginolyticus isolated from diseased fish produced more siderophore than that from marine environment. The extract of siderophore from V. alginolyticus could stimulate the growth of Escherichia coli mutant AN93. Under iron limitation,the growth rate was decreased and several outer membrane proteins were induced. Adding iron into the iron-limited medium the normal growth could be recovered.

Objective To explore the feasibility and value of preservation of left colonic artery (LCA) in dealing with inferior mesenteric artery (IMA) in laparoscopic anterior resection of rectal carcinoma.Methods The clinical data of 72 cases of laparoscopic anterior resection of rectal carcinoma from April 2010 to October 2013 were retrospectively analyzed including 32 cases with preservation of LCA (observation group) and 40 cases without preservation of LCA (control group).The blood loss,operative time,postoperative exhaust time,terminal ileum stoma,the number of lymph nodes removed around the root of IMA,the rate of lymph node metastasis around the root of IMA and prognosis were compared between two groups.Results There was no significant difference in the blood loss,operative time,postoperative exhaust time,terminal ileum stoma,the number of lymph nodes removed around the root of IMA,the rate of lymph node metastasis around the root of IMA between two groups (P > 0.05).No case in observation group needed to free the splenic flexure of colon and to make the terminal ileum stoma,while 3 cases in control group needed to free splenic flexure of colon because of blood supply disorder in the proximal intestine (P =0.046),and 4 cases underwent terminal ileum stoma following anastomosis (P =0.042).No anastomotic leakage occurred in observation group,while 2 cases of anastomotic leakage occurred in control group(P =0.090).After followed up for 6-48 months,no significant difference was found in local recurrence and liver metastasis in two groups (P > 0.05).Conclusion Laparoscopic anterior resection of rectal carcinoma with preservation of LCA in dealing with IMA can effectively retain the blood supply of proximal intestine.

Objective:To determine the inflammatory factor levels and inflammatory cell percentages in the patients with cough variant asthma (CVA ), and to clarify their potential role in the pathogenesis of CVA unresponsive to bronchodilator treatment.Methods:60 patients with CVA were randomly selected and divided into CVA unresponsive to bronchodilator treatment group (n=30)and CVA responsive to bronchodilator treatment group (n=30).As the same time 30 cases of healthy persons were used as normal control group.The levels of interluekin-8 (IL-8)and esoinophil cationic protein (ECP)in their induced sputum were detected,the classification of inflammatory cells in their induced sputum were observed, and their scores of cough symptom were recorded. Results:The IL-8 level in the induced sputum of the patients in CVA unresponsive to bronchodilator treatment group was higher than that in CVA responsive to bronchodilator treatment group and normal control group (P<0.05).The ECP level in the induced sputum of the patients in CVA unresponsive to bronchodilator treatment group was lower than that in CVA responsive to bronchodilator treatment group (P<0.05),but it was similar to the level in normal control group (P>0.05).The neutrophil percentages in the induced sputum of the patients in CVA unresponsive to bronchodilator treatment group were higher than those in CVA responsive to bronchodilator treatment group and normal control group (P<0.05).The scores of cough symptom of the patients in CVA unresponsive to bronchodilator treatment group was positively correlated with IL-8 level (r=0.764,P<0.01), and the scores of cough symptom of the patients in CVA unresponsive to bronchodilator treatment group was positively correlated with the neutrophil percentage in induced sputum (r=0.889,P<0.01).Conclusion:IL-8 and neutrophil may be associated with the incidence of CVA unresponsive to bronchodilator treatment. They can aggravate the inflammation and hypersensitivity of airway and cough symptom. The determination of IL-8 and neutrophil can be used as an accessory method in the diagnosis and j udgement of severity degree and curative effect of CVA in clinic.
