Objective To analyze the risk factors for traumatic cerebral venous sinus occlusion (CVSO)and to investigate the strategies of early diagnosis of traumatic CVSO. Methods The clinical data of 212 patients with moderate to severe closed traumatic brain injury from January 2012 to December 2015 were analyzed retrospectively. Logistic regression analysis was used to evaluate the risk factors for traumatic CVSO. Results Of the 212 patients with traumatic brain injury, 16.5%(35/212) patients had CVSO. Ten patients had CVSO of thrombotic type (typeⅠ), 16 patients had CVSO of compression type (typeⅡ), and 9 patients had CVSO of mixed type (typeⅢ). Logistic regression analysis showed that skull fracture (OR = 8.141; 95%CI: 3.224-20.840) and epidural hematoma of crossing venous sinus (OR = 3.179; 95%CI: 1.470-7.037) were the risk factors for CVSO, and the former was more significantly correlated with CVSO. Female gender was the risk factor for CVSO typeⅠ(OR =10.425; 95%CI: 1.831-30.053), epidural hematoma of crossing venous sinus was the risk factor for CVSO typeⅡ(OR = 5.766; 95%CI: 1.885-18.197), and skull fracture, epidural hematoma of crossing venous sinus, and the previous history of vein thrombosis was the risk factors for CVSO type Ⅲ(OR =18.005, 4.596, 11.394; 95%CI: 2.021-58.836, 1.144-19.525, 1.436-46.558). Conclusions In the early diagnosis of traumatic CVSO, the crossing venous sinus fracture line and epidural hematoma should be given attention. Attention should be paid to the history of venous thrombosis. MR venography and CT venography contributes to early diagnosis of CVSO.

Objective: To explore the feasibility of needling the Belt Vessel (BV) for low back pain. Methods: The relevant literature was systematically reviewed; the relationship between the BV and low back pain was illustrated; the clinical features of BV-related low back pain as well as the key points of acupoint selection in treatment were summarized, and the efficacy of needling the BV for treating low back pain was observed. Results: The BV is closely related to low back pain. The main clinical manifestations of BV-related low back pain include sagging distension in the low back, enlarged abdomen, and pain radiating to the groin. The main acupoints for treating low back pain via needling the BV include Mingmen (GV4), Wushu (GB27) and Ashi points near the transverse process of the third lumbar spine. Needling the BV can swiftly and effectively relieve both the low back pain and associated symptoms. Conclusion: Needling the BV can effectively alleviate the typical BV-related low back pain.

OBJECTIVE Explore the waysof cochlear implantation(CI)surgery technique for bilateral profound sensorineural hearing loss patients with otitis media and mastoiditis. METHODS CI was performed in 29 patients with different of otitis media and mastioditis,26 of them underwent a single-stage operation,and 3 had a two-stage operation,according to the degree and extent of lesion. For patients with mild inflammation,cochlear implantation was performed after complete eradication of inflammation at the same protocol the patients with severe inflammation underwent an intact canal wall tympanomastoidectomy or reconstructed it initially,cochlear implantation was performed after the initial procedures. RESULTS One- stage or tow-stage operations of CI were carried out for 29 patients with otitis media and mastoiditis. All electrodes were implanted successfully,in which the CI went normally and electrode array were protected well. None of the cases showed recurrence of infection during an average follow-up period of 2-8 years. CONCLUSION The CI could be performed in otits media and mastoiditis patients after reversionary surgery . Individual management based on the degree and extent of the local lesion was emphasized.
