As a common and frequently-occurring disease,glenohumeral instability is become one of disease which restrict upper limb activity. The diagnosis of this disease is easy, but it is very difficult to assess the degree of periarticular soft tissue injuries. With the development of magnetic resonance imaging and arthroscopy, MRA become the gold standard for evaluation of glenoid labrum, joint capsule and ligaments injury. The traditional manual reduction is a fast, simple method, but often can cause adverse consequences,such as rotator cuff tear,ligament relaxation,and habitual dislocation. Open operation can rebuild stability of joint,but with many new treatment methods,especially the arthroscopic reconstruction has gradually replaced the open operation, and become the mainstream trend, but for the long-term effect of capsular tightening surgery, rotator cuff gap closure is not clear,it is need further follow-up observation.

AIM: To study the effects of artemisunate on anoikis resistance in human breast cancer cells. METHODS: After breast cancer MCF-7 cells were treated with artemisunate, the growth of anchorage independence of breast cancer MCF-7 cells was examined in soft agar colony formation, and apoptosis of breast cancer were evaluated by terminal deoxynucleatidyl transferase-mediated deoxyuridine triphosphate nick end labeling (TUNEL) and DNA ladder. RESULTS: Artemisunate significantly inhibited the growth of anchorage independence of breast cancer MCF-7 cells in soft agar colon formation in a dose-dependent manner. Artemisunate induced apoptosis in breast cancer cells was conformed by DNA ladder and TUNEL assay, which was in a time-and dose-dependent manner. CONCLUSION: Artemisunate inhibits the growth of anchorage independence of breast cancer MCF-7 cells, which is related to anoikis.

Objective To study the clinicopathological features of C3 glomerulonephritis and the associations between plasma complement fragments level and clinical manifestations.Methods The clinical and pathological data of the 12 patients with C3 glomerulonephritis in our division from January 1999 to June 2010 were analyzed retrospectively.Concentrations of plasma factor B,Ba,C3,C3a,C4a and C5a were detected by commercial available sandwich ELISA kits on the day of renal biopsy.Results Ten of the 12 patients were C3 glomerulonephritis without MPGN,and the rest 2 were C3 glomerulonephritis with MPGN.All the patients presented proteinuria.Two of the 10 C3 glomerulonephritis patients without MPGN presented nephrotic range proteinuria,6 with microhematuria,1 with gross hematuria,and 2 with renal insufficiency.One of the 2 C3 glomerulonephritis patients with MPGN presented nephrotic range proteinuria,accompanied by microhematuria,hypertension and renal insufficiency.The other patient showed moderate proteinuria with normal renal function.Most of C3 glomerulonephritis patients without MPGN showed mild mesangial proliferative glomerulonephritis,and 4/10 patients had various degree cresentic formation.One C3 glomerulonephritis patient with MPGN had 47.1％ cresentic formation.The concentration of plasma C3 in C3 glomerulonephritis patients was normal,while the plasma factor B was significantly decreased,and the concentrations of plasma Ba,C3a,C4a and C5a were significantly elevated.The concentration of plasma Ba was positively correlated with the proteinuria level,while the concentrations of plasma C3a,C4a and C5a were not correlated with the levels of proteinuria or plasma creatinine.Conclusions Majority of these 12 patients were C3 glomerulonephritis without MPGN,manifests as nephritic syndrome clinically and mild mesangial proliferative glomerulonephritis histopathologically.Complement activation via alternative pathway may play an important role in the pathogenesis of C3 glomerulonephritis.
