2.Influence of tranilast on expression of OPN and interstitial ED1+ macrophages infiltration in rats with chronic cyclosporine A nephrotoxicity
Chinese Journal of Practical Internal Medicine 2006;0(20):-
Objective To evaluate the effect of tranilast on chronic cyclosporin A(CsA)nephrotoxicity rats and the possible mechanisms of protective effect of it.Methods Rats were on low salt diet and CsA was administered by gastric gavage at a dose of 20 mg/(kg?d)for 28 days,and tranilast was gave to these rats in a dose of 400 mg/(kg?d).The renal function and renal morphology were observed at1,2 and 4 weeks after administration of tranilast.Results CsA induced the corruption of normal condition and weight lost were markedly delayed after administration of tranilast.On histopathology tranilast attenuated tubular cells vacuolations as well as interstitial damage including interstitial ED1+ macrophages infiltration and focal interstitial fibrosis.Meanwhile,tranilast down-regulated the protein of OPN in kidney.Conclusion Tranilast can attenuate the structural changes of kidney in chronic CsA nephrotoxicity rats.Decreased CsA-related ED1+ macrophages,OPN up-regulation expression in the kidney may be related to mechanisms of protective effect of tranilast in the treatment of CsA induced chronic nephrotoxicity.

Objective To measure the concentration of the amniotic fluid EPO(AFEPO) and investigate the relationship between AFEPO levels and fetal hypoxia. Methods Their AFEPO and the umbilical vein serum EPO (UVSEPO) were measured thirty pregnancy induced hypertension pregnancies (PIH group) , 30 gestational diabetic pregnancies (Diabetic group) and 25 normal pregnancies (control group) were terminated by cesarean section by using a chemiluminescent enzyme labeled immunometric assay (CELIMA). Meantime, umbilical artery pH (UapH), base excess(UaBE) and UapO2 and so on were also measured. Results The mean concentrations of AFEPO and UVSEPO in PIH (1.42?0.33 and 1.63?0.37) and Diabetic group (1.53?0.25 and 1.81? 0.34) were significantly higher than those in control group (0.91?0.11 and 1.13?0.14), ( P

Objective:To investigate the role of the expression of E-cadherin(E-Cad) and tissue inhibitor of metalloproteinases-2(TIMP-2) in carcinogenesis and progression of colorectal cancer(CRC).Methods:The E-Cad and TIMP-2 expressions were studied immun ohistochemistrically in 30 specimens of colorectal adenoma and 60 specimens of CRC.Results:The expression rates of E-Cad were 87.10% in colorectal adenoma and 55.00% in CRC, the former was apparently higher than that of the later (P0.05);The significant relationship was observed between low TIMP-2 expression and Dukes stage, metastasis of lymph node and distant organs and poor prognosis.Conclusion:The detection of expression about E-Cad and TIMP-2 may be helpful to judge the malignant behavior and metastasis and prognosis with colorectal carcinoma,furthermore the expression of TIMP-2 may be used to know prognosis of patients.

Objective To examine the clinical effect and learning curve of endoscopic thyroidectomy via chest-areolar approach in the treatment of benign thyroid nodules. Methods From January 2012 to May 2016,49 patients underwent endoscopic thyroidectomies via chest-areolar approach in Xuanwu Hospital ,Capital medical university. The clinical characteristics ,prognosis and operation time were retrospectively analyzed. The patients were divided into 9 groups according to the surgical sequence ,and the learning curves were analyzed by using moving average method. Results 49 endoscopic thyroidectomies via chest-areolar approach were performed successfully. The average size of the nodules was(2.80 ± 0.62)cm. 10 patients underwent bilateral thyroidectomy and 39 underwent unilateral thyroidectomy. The average operation time was(157.49 ± 21.23)min. 2 cases received re-operation due to postoperative pathology of malignancy. There were no postoperative recurrent laryngeal nerve injuries. 11 patients suffered from asymptomatic hypocalcemia with parathyroid hormone in the normal range. All of the patients were satisfied with the cosmetic results. The learning curves indicated that 35 endoscopic thyroidectomies were needed to be performed in the early study stage. Conclusions For surgeons with experience of conventional thyroidectomies,endoscopic thyroidectomy via chest-areolar approach is feasible and safe for selected patients. There is a significant learning curve in the application of endoscopic thyroidectomy. In the early study stage of endo-scopic thyroidectomy,35 cases are basically required for beginning surgeons to practice the surgical operation.

Objective To study the roles of soluble intercellular adhesion molecule 1(sICAM 1) in the pathogenesis of pregnancy induced hypertension (PIH). Methods Serum levels of sICAM 1 were measured by enzyme linked immunosorbent assay(ELISA) in 65 women with PIH (PIH group : 15 mild PIH, 24 moderate PIH and 26 severe PIH) and 25 normal pregnant women (control group). The serum levels of IL 1? and TNF ? were measured by chemiluminescent ELISA at the same time. Results Serum concentrations of sICAM 1 were significantly higher ( P

Objective To explore the extent of axillary lymph node dissection in breast cancer patients with positive sentinel lymph nodes.Methods In this series,95 patients underwent complete axillary lymph node dissection (CALND) following positive sentinel lymph nodes identified and 97 patients underwent partial axillary lymph node dissection (PALND) at the absence of positive sentinel lymph nodes.The influence of different extent of axillary lymph node dissection was evaluated.Results The positive rate of level(Ⅰ + Ⅱ) non-sentinel lymph nodes (NSLN) and level Ⅲ lymph nodes was 68.4% and 29.5%,respectively,in CALND group.In PALND situation,57.9% CALND cases would have changed pathologic stage from pN1 to pN2 or pN3.But with level Ⅲ lymph node dissection followed PALND,only 2.1% cases had changed pathologic stage from pN2 to pN3.Multivariate logistic regression showed that the number of positive SLNs (OR =2.157) and positive rate of SLNs (OR =10.374) were risk factors for having positive level Ⅲ lymph nodes.CALND needed longer operation time and larger postoperative drainage volume.Conclusions In cases of breast cancer with ≥ 3 positive sentinel lymph nodes,complete axillary lymph node dissection should be considered.

Objective To investigate the effects of intrathecal(IT)CX3 CR1 neutralizing antibody(antiFKR)on morphine tolerance in rats with bone cancer pain(BCP)and the unlerlying mechanism.Methods Forty-eight adult female SD rats aged 3 months weighing 180-200 g were randomized into 4 groups(n =12 each):group I sham operation(S); group Ⅱ BCP + normal saline(NS); group Ⅲ BCP + IgG(IgG)and group ⅣBCP + anti-FKR.Bone cancer pain(BCP)was induced by injecting Walker 256 cancer cells 10 μl(400 cells/ μl)into the medullary cavity of right tibia in groups Ⅱ,Ⅲ and Ⅳ.Ten days later morphine 20 μg/kg was administered IT twice a day for 7 consecutive days.Starting from the 8th day NS,IgG and anti-KFR 10 μl was administered IT once a day for 3 consecutive days in groups Ⅱ,Ⅲ and ⅣⅣ respectively.Paw withdrawal threshold to yon Frey filament stimulation(MWT)and paw withdrawal duration(MWD)were determined bcfore(To,baseline)and at 3,6,9 day after intra-tibial cancer cell inoculation(T1.2,3),on the 3rd and 7th day of IT morphine(T4.5)and on the 3rd day of IT NS/lgG/anti-KFR(T6).The animals were killed at T6 after last pain behavior assessment.The lumbar segment(L4-6)of the spinal cord was removed for determination of the expression of CX3 CR1 protein(by Western blot),μ-opioid receptor and TRPV1 receptor(by immuno-histochemistry)in the dorsal horn of spinal cord.Results IT morphine significantly eased BCP at T4,but morphine analgesia was significantly reduced on the 7th day of IT morphine in the 3 groups indicating morphine tolerance which was significantly relieved by anti-KFR in group Ⅳ.IT anti-KFR significantly down-regulated CX3CR1 prolein and TRPVI receptor expression and up-regulated μ-opioid receptor in group Ⅳ as compared with IT NS and lgG in groups Ⅱ and Ⅲ.Conctusion IT anti-KFR can relieve morphine tolerance in the rats with bone cancer pain by up-regulating μ-opioid receptor and down-regulating CX3 CR1 protein and TRPVI receptor expression.
