Objective To study the incidence of pelvic adhesions in endometriosis(EM) and the relationship between pelvic adhesions and pain symptoms. Methods The incidence of pelvic adhesions, dysmenorrhea, chronic pelvic pain, dyspareunia, dyschizia in 480 patients with EM were studied retrospectively to evaluate the correlation between pelvic adhesions and the degree of pain symptoms. In accordance with the revised American Fertility Society classification (r-AFS), it was observed that 155 cases were in Stage Ⅰ,33 cases were in stage Ⅱ,108 cases were in stage Ⅲ and 184 were cases in stage Ⅳ. Results (1) Among 480 cases with EM, 72.3% (347/480) of patients have pelvic adhesions simultaneously, of which 25.2% (39/155) patients were in Stage Ⅰ, 78.8% (26/33) patients were in Stage Ⅱ, 90.7% (98/108) patients were in Stage Ⅲ and 100.0% (184/184) patients were in Stage Ⅳ. It was found that positive correlation existed between the degree of pelvic adhesions and clinical staging of EM(rs=0.870,P<0.01).(2) 61.0%(293/480) of patients presented dysmenorrhoea, of which the percentages of mild, moderate and severe dysmenorrhea were 52.2%(153/293), 26.6%(78/293), 21.2% (62/293), respectively. The rate of patients presenting chronic pelvic pain (CPP), dyspareunia and dyschezia were 23.8% (114/480), 15.4% (74/480) and 7.1% (34/480), respectively. (3) Ovarian adhesions was positively correlated with dysmenorrhea and CPP(rs=0.367 and 0.267,P<0.01). Adhesion of the bottom and posterior wall of uterus was positively correlated with dysmenorrhea and CPP (rs=0.336, 0.164,P<0.01); adhesions of fallopian tubes were positively correlated with dysmenorrhea, CPP and dyschezia (rs=0.283, 0.225 and 0.159, P<0.01). Adhesions of rectum was positively correlated with dysmenorrhea (rs=0.101,P<0.05). In addition to dyspareunia, the degree of pelvic adhesions was positively correlated with dysmenorrhea, CPP and dyschezia (rs=0.470, 0.273, 0.132, P<0.01). Conclusion Pelvic adhesions are characteristic lesions of endometriosis, the site and degree pelvic adhesions are closely correlated with pain symptoms.

Objective To study the influence of spinal instability after lamina decompression in symptoms and progno?sis. Methods The 76 patients were followed up for a minimum of 4 more years. The patients were divided into instability group (n=27) and non-instability (n=49) group according to the X-ray result of the final follow-up. The visual analogue scale (VAS) score, JOA score and improvement rate were compared between two groups at preoperation, 3-month after operation and the final follow-up. Results There were no significant differences in gender, age and mean follow-up time between two groups. There were no significant differences in VAS and JOA scores before surgery, 3-month after surgery and final follow-up between two groups. Postoperative VAS score decreased and JOA score increased with the increase in follow-up time (P<0.05). There were no significant differences in improvement rate [(80.0±8.8)%vs (83.6±11.7)%] and improvement ratio [81.48%(22/27) vs 61.22%(30/49)] between two groups (P > 0.05). Conclusion Although some patients show instability even with lumbar spondylolisthesis after lamina decompression on radiograph,which is no correlation with improvement of symptoms. With appropriate indications, lamina decompression is a simple and effective surgical method,which also retains the spinal movement function.

Aim To investigate the effects of Ang Ⅱ receptor antagonist irbesartan on the expressions of connective tissue growth factor(CTGF) and membrane-type 1 matrix metalloproteinase(MT1-MMP) in high glucose-cultured rat glomerular mesangial cells(GMCs).Methods High concentration glucose and irbesartan were used to stimulate the cultured rat GMCs in vitro.The mRNA and protein expressions of CTGF and MT1-MMP were detected with semi-quantitative RT-PCR and Western blot.The secreted collagen Ⅳ in the supernatants of the GMCs was detected by enzyme-linked immunoadsorbent assay(ELISA).Results Compared with control group,the expressions of CTGF were continuously increased in GMCs under high concentration glucose medium;otherwise the mRNA and protein levels of MT1-MMP in GMCs were decreased in a time-dependent manner at the same time.These changes were accompanied by increased secretion of collagen Ⅳ.Irbesartan could inhibit those changes induced by high glucose.Conclusions High glucosecould induce the expression of CTGF and inhibit the expression of MT1-MMP in GMCs.Irbesartan could inhibit the secretion of ECM in GMCs under high concentration glucose medium,partly by regulating the expressions of CTGF and MT1-MMP.

Objective To investigate the effect of suppressor of cytokine signaling-1 (SOCS-1)on expression of monocyte chemoattractant protein-1 (MCP-1)in human glomerular mesangial cells (HMCs) under high concentration of glucose. Methods Stable transfections of HMC with pCR3.1 vector and pCR3. 1-SOCS-1 were performed with hpofectamine 2000, and cells were selected with geneticin. Cells were stimulated with low glucose (LG, 5.5 mmol/L), high glucose (HG, 30 mmol/L), LG plus mannitol (24.5 mmol/L) and AG490 (10 μmol/L). The protein expression levels of SOCS-1, signal transducer and activators of transcription 1,3 (STAT1, STAT3),p-STAT1 and p-STAT3 were observed by Western blotting. The protein synthesis of MCP-1, FN and type Ⅳ collagen in the supernatants of the HMCs were detected by ELISA and radioimmunoassay. The expression level of SOCS-1 and MCP-1 mRNA was measured by BT-PCR.Results HG induced the expression of SOCS-1 protein and mRNA in HMCs in time-dependant manner, peaked at 4 h, and gradually decreased to baseline at 24 h. Compared with low glucose control group, the phosphorylation levels of STAT1 and STAT3 and the expression of MCP-1 mRNA [(0.39±0.05) vs (0.16±0.02)]were significantly increased in HMCs under high glucose medium (P <0.01 ). Exposure of HMCs to high glucose conditions showed high concentration of MCP-1 [(459±67) ng/L vs (241±19) ng/L], fibronectin [(5.84±0.61) mg/L vs (3.41±0.31) mg/L]and type Ⅳ collagen [(16.45±2.30) μg/L vs (9.56±1.52) μg/L]in the supernatants (all P<0.01).Overexpression of SOCS-1 inhibited the phosphorylation levels of STAT1 and STAT3 and the expression of MCP-1 mRNA [(0.34±0.04) vs (0.42±0.05)]in HMCs under high glucose condition (all P<0.05). Compared with vector control group, the concentration of MCP-1 [(387±47) ng/L vs (463±56) ng/L], fibronectin [(4.61±0.57) mg/L vs (5.76±0.74) mg/L]and type Ⅳ collagen [(13.4±2.32) μg/L vs (17.1±2.57) μg/L]was decreased in supernatants of HMCs with SOCS-1 overexpression (all P<0.05). Compared with HG group, the expression of MCP-1 mRNA (0.31±0.04) and the concentration of MCP-1 [(361±53) ng/L], FN [(5.46±0.71) mg/L]and type Ⅳ collagen [(15.2±1.97) μg/L]in supernatants were decreased in HMCs treated with AG490.Conclusion Overexpression of SOCS-1 inhibits overproduction of MCP-1 and ECM proteins in HMCs under high glucose conditions, which may be partly by regulating the phosphoryhtion of STAT1 and STAT3.
