Objective To observe the effects of parathyroidectomy(PTX) on bone metabolism and bone mineral density(BMD) in maintenance hemodialysis patients with secondary hyperparathyroidism (SHPT).Methods A total of 26 dialysis patients with SHPT were treated with PTX.Serum calcium,phosphorus,alkaline phosphatase(ALP) levels were determined by standard methods.The levels of serum intact parathyroid (iPTH),osteocalcin (OC),procollagen type Ⅰ aminoterminal propeptide (PINP),β-crosslaps (β-CTX) were measured by chemiluminescence.BMD was measured by dual energy X ray absorptiometry.iPTH,OC,PINP,β-CTX,serum calcium,phosphorus,ALP were measured before parathyroidectomy and 1,3,6,12,18,24 months after operation.Lumbar spine (LS) and femoral neck (FN) BMD were measured before and 24 months after PTX.Results Compared with that before operation,serum OC[(104.49±25.42) μg/L vs (695.46±355.62) μg/L,P ＜ 0.01] and PINP levels [(248.36 ± 159.38) μg/L vs (809.28 ± 283.50) μg/L,P＜ 0.01] progressively decreased 3 months after PTX,and serum β-CTX levels [(1.60±0.64) μg/L vs (3.37±1.34) μg/L,P ＜ 0.01] decreased 1 month after PTX.Compared with that before operation,BMD levels increased 24months after PTX in LS[(0.88±0.23) g/cm2 vs (0.78±0.23) g/cm2,P ＜ 0.01] andFN[(0.96±0.19) g/cm2 vs (0.84±0.24) g/cm2,P ＜ 0.01],and Z-scores were also increased in both LS[(-1.24±0.55) vs (-1.66± 0.24),P ＜ 0.01] and FN[(-1.51 ±0.72) vs (-1.93 ± 0.40),P ＜ 0.01].Correlation analysis showed that baseline iPTH was positively correlated with ⊿Z-score in FN (r=0.584,P=0.002) and LS (r=0.400,P=0.043),and so did the OC with ⊿Z-score in FN (r=0.651,P ＜ 0.001) and LS (r=0.509,P=0.008).Conclusion The levels of OC,PINP and β-CTX are reduced and BMD is improved in hemodialysis patients with SHPT after PTX.

Objective To investigate the relationship of nuclear factor kappa B(NF-κB),Bcl-2 and Bax with limb function after acute spinal cord injury in rats. Methods Forty-eight rats were divided at random into a control group and an experimental group with 24 rats in each.The spinal cords of the rats in the experimental group were injured at the T8,9,10 level through moderate compression.Four hours,8 h,and 1,3,7 and 14 days after the injury,4 rats were selected randomly from each group and graded with a BBB score.They were then sacrificed and their spinal cords were collected.Immunohistochemical measurements were used to observe the expression of NF-κB, Bcl-2 and Bax. Results NF-κB,Bcl-2 and Bax were observed in the injured spinal nerve cells of rats in the exper imental group but were absent in the control group.After injury,the expression of these factors increased at first and then decreased.BBB scores for limb function increased gradually.No correlation was found between the changes in NF-κB and Bcl-2,but the expression of NF-κB was positively correlated with that of Bax.There was negative correla tion between NF-kB levels and BBB scores,and between NF-kB levels and the ratio of Bcl-2 to Bax. Conclusion In rats,there is a close negative correlation between NF-kappa B levels,the ratio of Bcl-2/Bax and limb function after acute spinaI cord iujury.
