Background Glucocorticoid is a common drug for treatment of thyroid-associated ophthalmopathy (TAO) with good effectiveness.But some adverse reactions of glucocorticoid are inevitable.At recent years,99technetium-methylene bisphosphonate(99Tc-MDP) is being paid more and more attentions in the treatment of TAO,but its effectiveness and safety is worthy of comparison to traditional treatment methods.Objective This study was to evaluate the efficacy of treatment with intravenous injection of 99Tc-MDP for TAO.Methods The Cochrane Library,CNKI,PubMed,Wanfang database,Weipu net were searched in computer and Google Scholar was searched manually.The randomized controlled trail (RCT) of intravenous injection of 99Tc-MDP for TAO were collected from establishment of database through April,2012.The quality of included literature was assessed based on the methodology of the study.The evaluating indexes included the primary treating outcomes,such as total efficacy,exophthalmic extent and recurrence rate as well as secondary outcomes such as adverse effect.RevMan 5.1 software was used for Mate analysis.Results A total of 11 RCTs were identified with 706 patients.Subgroup analysis was carried out based on the outcome measures and intervention.No significant difference was found in the overall effective rate between intravenous injection of 99Tc-MDP and immunosuppressive treatment (RR =0.96,95 ％ CI:0.76 to 1.22,P=0.740).However,the effective rate was significant different between intravenous injection of 99Tc-MDP and oral prednisone (RR =1.25,95 ％ CI:1.06-1.46,P =0.007) or between intravenous injection of 99 Tc-M DP and the blank control group (RR =2.53,95 ％ CI:1.68-3.81,P =0.000).Significant difference also was found in the total effective rate between intravenous injection of 99Tc-MDP with methyprednisone and methyprednisone alone (RR =1.27,95％ CI:1.05-1.53,P =0.010).There were significant differences in the effective rate of proptosis between intravenous injection of 99Tc-MDP and oral prednisone (RR=2.02,95％ CI:1.44-3.56,P=0.020).The recurrence rate of TAO was significant different between intravenous injection of 99Tc-MDP and oral prednisone (RR =0.51,95％ CI:0.33-0.78,P=0.002).Less adverse responses were seen in the intravenous injection of 99Tc-MDP group than the oral prednisone group and immunosuppressive treatment group.Conclusions Intravenous injection of 99Tc-MDP for TAO appears to be of a similar effectiveness to immunosuppressive method.The combination of intravenous injection of 99Tc-MDP with methyprednisone seems to be more effective than methyprednisone alone,with little systemic adverse effect after application.

Objective To investigate the correlation between invasion ability and cytoskeleton remodeling of hepatocarcinoma cell by atomic force microscopy (AFM) and to explore mechanical properties during genesis,development and invasion of hepatocellular carcinoma (HCC).Methods Four HCC cell lines (MHCC-97H,MHCC-97L,SMMC-7721 ,Huh-7 )with different invasive ability were studied.Mechanical parameter (Young′s modulus)was measured by AFM.The pattern of cytoskeleton remodeling of HCC cell lines with different invasive ability was detected by immunofluorescent staining. The difference of cell invasive ability was tested by cell scratch experiment in other to verify mechanical data.Kruskal-Wallis H test was used to compare the differences between groups.Results The results of AFM indicated that Young′s modulus of cytoplasma area and nucleus area decreased gradually as cell invasion ability increased (χ2 =472.78,622.43,both P <0.01).According to invasive ability from low to high,Young′s modulus of cell cytoplasm area of Huh-7,SMMC-7721 ,MHCC-97L and MHCC-97H were 1 602.43 (845 .48,3 317.25)Pa,1 055 .28 (367.48,2 280.77)Pa,1 026.78 (369.20,2 019.96)Pa and 503.12 (366.11 ,700.31)Pa,respectively.Young′s modulus of cell nucleus area of Huh-7,SMMC-7721 ,MHCC-97L and MHCC-97H were 2 823.98 (1 262.78,4 440.07 )Pa,1 313.43 (590.71 , 2 678.62)Pa,1 285 .17 (583.29,1 961 .19)Pa and 655 .57 (441 .29,943.39)Pa,respectively.The results of immunofluorescent staining showed that the stronger the cell invasive ability,the worse cytoskeletal integrity and more irregular cell microfilament distribution. In cell scratch assay, the migration rate of MHCC-97H was 46.67% in 24 h and 86.47% in 48 h,that of MHCC-97L was 45 .70%in 24 h and 82.86% in 48 h,that of SMMC-7721 was 39.41 % in 24 h and 79.85 % in 48 h and that of Huh-7 was 34.60% in 24 h and 72.09% in 48 h,which showed that the cell migration orderly in creased as the cell invasion ability increased.Conclusions It seemed that HCC with higher invasive ability had lower Young′s modulus,softer cell,stronger deformability,worse cytoskeleton integrity and more irregular cell structure,and vice versa.

The results showed that 9 strains presented cytotoxic activities to at least one of the tested tumor cells, five strains exhibited strong antimicrobial activity against Staphylococcus aureus, one strain had inhibitory effect on Phytophthora parasitica. It was evidently that the endophytic fungi of C. hainanensis are potential resources to find valuable bioactive components.

Objective To investigate the effect of acupuncture combined with minimally invasive hematoma aspiration on a rabbit model of brain injury in the acute stage of intracerebral hemorrhage (ICH). Methods A total of 65 healthy New Zealand white rabbits were randomly divided into a sham operation (SO) group, an ICH group,a hematoma aspiration (HA) group, and an acupuncture and hematoma aspiration (AHA) group. Models of ICH were established in the latter three groups. The HA group was treated with minimally invasive hematoma aspiration and the AHA group was treated with both acupuncture and minimally invasive hematoma aspiration. At 6 hours and 1, 3 and 7 days after the ICH models were established, brain water content (BWC) was measured, and the expression of matrix metalloproteinase-9 ( MMP-9 ) in the rabbits' brains was detected by immunohistochemistry. MMP-9activity was detected by gelatin zymography. Results The BWCs of the ICH group, HA group and AHA group rabbits were significantly higher than those of the SO group. The BWCs of the HA group and AHA group animals descended significantly more than those in the ICH group as time went on, especially on the 3rd day in the AHA group. Immunohistochemistry and gelatin zymography showed that the expression and activity of MMP-9 in these test groups decreased with time, especially on the 3rd day in the AHA group. Conclusions Acupuncture combined with hematoma aspiration can reduce injury in the acute stage of ICH, and inhibition of the expression of MMP-9 may be the mechanism.
