Objective To analysis the level of 25 hydroxy vitamin D[25(OH)D] in Xinjiang Han and Uyghur elderly male patients with T2DM and osteoporosis, and the correlation between 25(OH)D levels and bone mineral density(BMD). Methods We collected 281 cases of T2DM patients from Hans and Uyghurs, divided them into four groups according to the nationality and BMD: Han non-osteoporosis(NOP) group including 127 cases(group A), Han osteoporosis(OP) group 21 cases(group B), Uyghur NOP group 103 cases(group C), Uyghur OP group 30 cases(group D). Recorded and compared their 25(OH)D levels, and analyzed the correlation between 25(OH)D levels and BMD. Results In the same nationality,the level of 25(OH)D in group B were lower than those in group A(P<0.05), and group D were lower than those in group C(P<0.05); In T2DM patients combined with OP, the levels of 25(OH)D in group D were lower than those in group B(P<0.05); Correlation analysis showed that 25(OH)D was positively correlated with BMD. Conclusion The level of 25(OH)D in elderly male patients with T2DM combined with osteoporosis, those of Uyghurs are lower than those of Hans. T2DM patients with lower 25(OH)D level are more likely to combine OP. The 25(OH)D level test may help to identify the risk of combining OP in T2DM patients.

Objective To assess the 25-hydroxyvitamin D (25-OH-D) and interleukin-17(IL-17) status in patients with systemic lupus erythematosus(SLE) and its clinical significance. Methods 40 SLE patients along with 20 matched controls were collected. Chemilumineseent immunoassay (CLIA) was used to detect the levers of serum 25-OH-D. The levels of serum IL-17 were evaluated using enzyme-linked immunosorbent assay (ELISA). Results Serum 25-OH-D level in SLE patients was significantly lower than in healthy controls (P<0.01). Serum 25-OH-D level in active SLE patients was significantly lower than in inactive SLE patients (P<0.01). Lever of IL-17 was significantly higher in SLE patients than in healthy controls (P<0.01). Insufficiency of 25-OH-D was related to renal disorders. Serum 25-OH-D level was negatively correlated with systemic lupus erythematosus disease activity index (SLEDAI) scores(r=-0.844, P<0.01)and serum levels of IL-17(r=-0.596, P<0.01). Conclusion Insufficiency of 25-OH-D is prevalent in SLE patients. It is associated with nephritis, disease activity and high serum levels of IL-17, thus it may play an important part in the inflammatory process in SLE.

Objective To investigate the value of stamp pressure(SP), somatosensory and motor evoked potentials(SEP,MEP) monitoring in carotid endarterectomy. Methods 19 patients with carotid endarterectomy were retrospectively analyzed.SP, SEP and MEP were monitored during the operation.National Institutes of Health Stroke Scale (NIHSS) and Modified Rankin Scale (mRS) were used to evaluate the neurological function before and 6 months after surgery. Results Intraluminal shunting was not performed in 10 patients with normal SP, SEP and MEP.However, intraluminal shunting technique was used in 5 patients (SP<50 mmHg and SEP fluctuation decreased by 50％) and 3 patients (SP≥50 mmHg and SEP fluctuation decreased by 50％).1 patient showed the fluctuation of MEP decreased by 50％, while SP and SEP was normal, no shunting was performed.All patients were successfully operated, and no mortality occurred.The mRS score, not the NIHSS score, revealed statistically difference between preoperation and 6 months after surgery (P<0.05). Conclusion The combination of SP, SEP and MEP monitoring maybe useful for preventing ischemic stroke after carotid endarterectomy, increasing the safety of surgery.
