OBJECTIVE: To evaluate the partial biomechanical properties of the posterior occipital muscles (rectus capitis posterior major, rectus capitis posterior minor, and obliquus capitis inferior) in patients with cervical vertigo. METHODS: A total of 30 patients with cervical vertigo admitted from April 2024 to September 2024 were included in the vertigo group, and 30 age-and gender-matched healthy subjects were recruited as the normal group. In the vertigo group, there were 21 females and 9 males, with an average age of (24.00±2.25) years;in the normal group, there were 22 females and 8 males, with an average age of (23.00±3.00) years. Shear wave elastography was used to measure the thickness and stiffness of the posterior occipital muscles in both groups. RESULTS: In the vertigo group, there were no statistically significant differences in the Young's modulus values (E) of stiffness of the posterior occipital muscles (rectus capitis posterior major, rectus capitis posterior minor, obliquus capitis inferior) between the left and right sides(P>0.05). The Young's modulus values(E) of stiffness of the right posterior occipital muscles (rectus capitis posterior major, rectus capitis posterior minor, obliquus capitis inferior) in the cervical vertigo group were (39.66±8.21) kPa, (45.61±5.85) kPa, and (43.73±5.22) kPa, respectively, which were significantly higher than those in the normal group 33.97(17.76) kPa, 41.38(8.99) kPa, 38.27(12.58) kPa, with statistically significant differences (P<0.05). In the vertigo group, the Young's modulus values(E) of stiffness of the left rectus capitis posterior major and left obliquus capitis inferior were (40.41±9.13) kPa and (42.11±6.20) kPa, respectively, which were significantly greater than those in the normal group (33.30±11.31) kPa, 38.94(14.62) kPa, with statistically significant differences(P<0.05);however, there was no statistically significant difference in the left rectus capitis posterior minor between the two groups(P>0.05). In the vertigo group, there were no statistically significant differences in the stiffness of the posterior occipital muscles (rectus capitis posterior major, rectus capitis posterior minor, obliquus capitis inferior) between the left and right sides(P>0.05). Additionally, there were no statistically significant differences in the thickness of the bilateral posterior occipital muscles between the vertigo group and the normal group (P>0.05). CONCLUSION The posterior occipital muscles of patients with cervical vertigo are stiffer than those of healthy individuals, while there is no significant difference in muscle thickness between the two groups.

Objective To evaluate the potential of the BIBP-H fluorescent probe in the detection of the oxidative stress levels after cerebral ischemia-reperfusion(CIRI).Methods In vitro,the potential of BIBP-H probe was in detection of oxidative stress was first assessed with fluorescence imaging in rat neuroblastoma(B104)cells after L-glutamic acid stimulation.And then,the effects of edaravone and dexborneol(EDA)and glutathione(GSH)pretreatment on the fluorescence intensity were evaluated.Later,a totally of 28 male C57BL/6 mice were randomly assigned into four groups:transient middle cerebral artery occlusion(tMCAO)group,EDA+tMCAO group,GSH+tMCAO group,and sham group.After 1.5 h ischemia and 12 h reperfusion,the mice were treated with BIBP-H via tail vein injection.In vivo,ex vivo,and tissue fluorescence imaging were utilized to evaluate the probe's cerebral ischemia-reperfusion injury(CIRI).Results ① BIBP-H probe did not exhibit fluorescence signals in cultured B104 cells,but showed red fluorescence in B104 cells treated with L-glutamic acid.The signals significantly decreased when pretreated with EDA or GSH.② Both the sham-operated mice intravenously injected with the BIBP-H probe and the tMCAO mice without injection of the probe showed negative results in in vivo fluorescence imaging.③ tMCAO mice treated with BIBP-H exhibited red fluorescence signals in the ischemic hemisphere in vivo,with significantly reduced fluorescence intensity after EDA or GSH infusion during reperfusion ④ The fluorescence area examined with BIBP-H was consistent the cerebral infarction area detected with triphenyltertrazolium.Conclusions The BIBP-H probe effectively monitored oxidative stress levels both in vivo and in vitro,demonstrating its potential in CIRI detection.
