OBJECTIVETo evaluate effects of different treatments on patients with osteoporotic vertebral fracture after percutaneous kyphoplasty in pain and function.

METHODSFrom March 2010 to March 2012,138 patients (165 vertebrae) with thoracic and lumbar vertebral osteoporotic fracture were randomly divided into three groups (control group, treatment group and comprehensive group), 46 cases in each group, and all patients were treated by PKP. Control group were treated with calcium and calcitriol after operation, treatment group added salmon calcitonin see calcimar based on control group, comprehensive group added incrementality waist musculi dorsi function exercise based on treatment group. VAS, ODI scores and BMD before operation, 3 d, 2 weeks, 1 month, 6 months and 12 months after operation were detected and compared.

RESULTSAll operation were performed successfully,38 cases (45 vertebrae) in control group, 36 cases (44 vertebrae) in treatment group and 40 cases (49 vertebrae) were obtained complete following up, there was no significant meaning in following time among three groups (P>0.05). Postoperative VAS and ODI scores at 3 d, 2 weeks and 1 month among three groups were lower than that of before operation (P<0.01). Compared with control group, postoperative VAS score at 3 d, 2 weeks and 1 month were decreasedin treatment group and comprehensive group, but there was no significant meaning in ODI scores (P>0.05). At 6 and 12 months after operation,there was no significant differences in VAS and ODI between control group and treatment group (P>0.05), while VAS score in comprehensive group decreased much than other two groups,decreased continuously (P<0.01). At 12 months after operation, BMD among three groups were increased more than preoperative,and BMD in comprehensive group was more obviously than that of in control and treatment group.

CONCLUSIONPKP, an effective method for the treatment of thoracic and lumbar vertebral osteoporotic fracture, could improve short-term clinical effects by adding calcitonin with calcium supplements and activated vitamin D. Waist musculi dorsi function exercise could improve long-term clinical effects of PKP and improve quality of life.

Objective To observe the different effects of iodine excess on inducing two strain mice thyroiditis. Methods NOD and Balb/c mice, each having 14 mice, were divided into NaI and control group. The mice were given 0.05% NaI water for 8 weeks in NaI group. RIA and ELISA were used respectively to detect TT4, TgAb, TPOAb and TSH level in serum. Morphology changes of thyroid and apoptosis of thyrocytes stained by immunohistochemistry were observed under light microscope. Lymphocytic proliferation of cervical lymph node and spleen to responding to Tg were detected by MTr method. Results After intake of iodine water for 8 weeks, NOD and Balb/c mice showed relative quality of thyroid in Nal group[(104.83±14.52), (155.79±20.77)mg/kg]obviously increased compared with control group[(71.80±20.42), (105.15±21.98)mg/kg, t values:-3.293,-4.429, all P< 0.01)], enlarged follicular lumen with colloid accumulation were observed in thyroid. Serum level of TT4 in Nal group [(29.52±4.42), (19.53± 2.35)nmol/L]to control group[33.40±5.38), (23.47±6.22)nmol/L]of NOD and Balb/c mice showed a decreasing tendency(t values: 1.374,1.567, all P > 0.05). TSH of Nal group showed an increasing tendency in Balb/c mice[(4.14±1.71)μg/L, compared with control [(3.55±1.41)μg/L, t values:-0.705, P > 0.05]and obviously increased in NOD mice [(6.98±0.66)μg/L, compared with control[(555±056)μg/L, t values:-3.562, P< 0.01], but no change of TgAb and TPOAb level in Nal group(1281,1364 cpm, 2.50×103, 0.14×103U/L were observed, compared with control(1297,1220 cpm, 3.17×103,0.03×103 U/L; Zvalues:-0.081,-0.703, -0.244,-1.293, all P > 0.05). In NOD mice NaI group, apoptosis of thyrocytes was more intense than Balb/c mice, obvious infiltration of lymphoeytes, disorganization and focus fibrosis was seen in thyroid. The cell amount of NaI group increased in NOD mice lymph node and spleen cells[(1.100±0.014), (1.076±0.033)]were more than that in the control group [(0.993±0.011), (1.005±0.003), t value:-11.672,-4.314, P < 0.01). Conclusions Iodine leads to enlargement of thyroid and malfunction of thyroid in Balb/c mice. Besides, NOD mice have generate inflammatory reaction in thyroid and produced sensitized lymphocytes to Tg. Iodine excess can induce NOD mice to occur autoimmune thyroiditis.

Epithelial-to-mesenchymal transition (EMT) plays a critical role in cancer metastasis,and is relevant to the inflammatory microenvironment.Lipopolysaccharide (LPS),a cell wall constituent of gram-negative bacteria,has been reported to induce EMT of cancer cells through TLR4 signal.We previously reported that LPS promoted metastasis of mesenchymallike breast cancer cells with high expression of cyclin D 1 b.However,the role of cyclin D1b in LPS-induced EMT has not been fully elucidated.In the present study,we described that cyclin D1b augmented EMT induced by LPS in MCF-7 breast cancer cells.Cyclin D1b markedly amplified integrin αvβ3 expression,which was further up-regulated under LPS stimulation.Our results showed ectopic expression of cyclin D1b promoted invasiveness of epithelial-like MCF-7 cells under LPS stimulation.Additionally,LPS-induced metastasis and EMT in MCF-7-D1b cells might depend on αvβ3 expression.Further exploration indicated that cyclin D1b cooperated with HoxD3,a transcription factor promoting αvβ3 expression,to promote LPS-induced EMT.Knockout of HoxD3 repressed LPS-induced EMT and αvβ3 over-expression in MCF-7 cells with high expression of cyclin D1b.Specifically,all these effects were in a cyclin D1a independent manner.Taken all together,LPS up-regulated integrin αvβ3 expression in MCF-7 cells with high expression of cyclin D 1b and induced EMT in breast cancer cells,which highlights that cyclin D1b may act as an endogenous pathway participating in exogenous signal inducing EMT in breast cancer cells.
