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.

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.

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.

AIM:To investigate the differences among Lenstar 900, A-scan ultrasound and keratometer in measurement of axial length ( AL ) , anterior chamber depth ( ACD ) and corneal curvature ( K1 , K2 , Km ) , and evaluate the consistency of the instruments, with the purpose providing references for the clinical application of Lenstar 900.
METHODS: In this study we picked up 36 patients ( 50 eyes ) underwent cataract surgery, and lens nucleus hardness were under level IV. Before the operation, AL, ACD and K1 , K2 , Km were measured by Lenstar 900, A-scan ultrasound and keratometer respectively. The differences between the results were compared by the paired t-test. The correlation of the results was analyzed by Pearson correlation analysis, and the consistency was measured by Bland-Ahamn method.
RESULTS: The mean AL and ACD values measured by Lenstar 900 and A-scan ultrasound had no significantly statistic differences (P>0. 05). The K1, K2, Km measured by Lenstar 900 and keratometer were not significantly statistical different (P>0. 05). The results measured by these three instruments had close linearity correlation ( r>0.9, P<0. 01). The consistency of the results was well in Bland-Ahamn analysis.
CONCLUSION:The preoperatively biometric result of Lenstar 900, A - scan ultrasound and keratometer in patients with cataract are all reliable, and they can be substituted by each other. However, Lenstar 900 can not only measure AL, ACD and corneal curvature at the same time, but also cornal thickness, lens thickness, white to white, pupil size, optical axis eccentricity, retinal thickness and so on. It has a number of advantages such as non-touching, convenient and efficient, and can be recommended to use widely.

Objective To investigate the effect of resveratrol on the proliferation and invasion of human pancreatic cancer PANC-1 cells. Methods Five groups including blank control group, 0. 1% dimethylsulfoxide (DMSO) group and resveratrol groups (50, 100, 200 μmol/L) were established. The proliferation of PANC-1 cells was detected by MTT assay. The apoptosis and cell cycle change were analyzed by flow cytometry. The invasive ability of PANC-1 cells was observed with a Transwell cell culture chamber. The expressions of Bax, Bcl-2,matrix metalloproteinases 2 (MMP-2) and 9 (MMP-9) of the PANC-1 cells were assayed by real-time quantitative PCR and Western blot. All data were analyzed using the analysis of variance. Results ( 1 ) The inhibition rate of resveratrol on the proliferation of PANC-1 cells was 0 in the blank control group, 3.25% ±0.42% in the 0. 1% DMSO group, 13.23% ± 1.68% in the 50 μmol/L of resveratrol group, 42.25% ± 3.20% in the 100 μmol/L of resveratrol group, and 56.94% ±5.31% in the 200 μmol/L of resveratrol group. There was a significant difference in the inhibition rate among the five groups (F=460. 10, P<0.05). (2) The apoptosis rate was 0.05% ±0.03% in the blank control group, 3.39% ± 1.77% in the 0. 1% DMSO group, 6.92% ± 1.85% in the 50 μmol/L of resveratrol group, 19.05% ± 2.01% in the 100 μmol/L of resveratrol group, and 27. 17% ±6.43% in the 200 μmol/L of resveratrol group. There was a significant difference in the apoptosis rate among the five groups (F = 38.84, P < 0.05). (3) There was no significant effect of 0. 1% DMSO on the cell cycle of PANC-1 cells. The number of PANC-1 cells in the G0/G1 and S phase was increased. (4) The average number of invading PANC-1 cells was 61 ± 13 in the blank control group, 54 ± 13 in the 0. 1% DMSO group, 48 ± 15 in the 50 μmol/L of resveratrol group, 23 ±6 in the 100 μ mol/L of resveratrol group and 18 ±7 in the 200 μmol/L of resveratrol group. There was a significant difference in the number of invading PANC-1 cells among the five groups (F = 69.08, P < 0.05 ). (5) There were up-regulated mRNA and protein expressions of Bax and down-regulated mRNA and protein expressions of Bcl-2, and the expressions of MMP-2 and MMP-9 of the PANC-1 cells were inhibited in the resveratrol groups. The changes of the protein expressions of Bax, Bcl-2, MMP-2, MMP-9 were consistent with the changes of the mRNA expressions of the four indexes. Conclusion Resveratrol can significantly inhibit the proliferation and invasion, as well as induce apoptosis of PANC-1 cells in vitro.
