Patients with spinal cord injury would suffer many complications including hip abnormities. Few reports on spinal cord injury with hip dislocation had been published because of a lower incidence and difficulty to be found in clinical practice. This paper reviewed epidemiology, etiology, diagnosis, prevention and treatment of hip dislocation after spinal cord injury.

BACKGROUND:With the development of industrial society and traffic, the incidence of spinal cord injury has gradualy increased. In addition to radiological laboratory examinations, the neurophysiological test also becomes an effective way of auxiliary examination. Due to the high accuracy and easy operating, neurophysiological test is widely used and the evoked potentials play a role in this project. OBJECTIVE:To summarize the application of somatosensory evoked potentials and motor evoked potentials in rabbits of spinal cord injury. METHODS:A computer-based online research of CNKI and PubMed databases was performed with the key words of “spinal cord injury; evoked potentials; animal models” in Chinese and English. Finaly 33 articles were included in the analysis according to the inclusion and exclusion criteria. RESULTS AND CONCLUSION:The operational approach, waveform analysis, application value, influencing factor of somatosensory evoked potentials and motor evoked potentials were determined in details, the correlation between evoked potentials and prognosis assessment in animals was also detected. Somatosensory evoked potentials is a good indicator for the evaluation of dorsal funiculus of spinal cord, it is easy to operate and reflects the changes of sensory functions. Motor evoked potentials can provide sensitive diagnosis of spinal cord diseases, and they wil be used as a means to assess the spinal cord injury during rehabilitation. The combination of the two can provide a more accurate result.

[Objective] To analyze relations between alcoholic liver disease(ALD) and gut-liver axis, and the intervention effects of Linderae radix(LR) on both of them. [Methods] Research reports about ALD,gut-liver axisand LR on anti ALD at home and abroad in recent years were reviewed, and effects ofgut-liver axisin the occurrence and development of ALD and LR on ALD treatment were summarized. [Results] Recent studies show that there is an abnormalgut-liver axisin ALD,gut permeability and intestinal endotoxemia(IETM) induced by excessive alcohol consumption is one of the key pathogenic factors for the occurrence and development of ALD. Improving intestinal functions to alleviate IETM would be an efficient way to treat ALD. Linderae radix (LR) is a traditional Chinese medicine commonly used for Qi-regulating in clinic ,it possesses a good effect for gastrointestinal function regulation and as reported in recent researches,it has shown a good protective effect on ALD by improving the abnormal gut-liver axisand alleviating IETM. [Conclusions] The abnormalgut-liver axisinduced by excessive alcohol intake is the key factor for ALD formation and development. LR possesses a protective function on ALD viagut-liver axisimprovement.

[Objective]To investigate the medium-term outcomes of surgical treatment of vertigo secondary to cervical spinal instability.[Method]From Oct.2000 to Jun.2006,28 patients underwent operation for vertigo secondary to cervical spinal instability and were followed prospectively.There were 21 females and 7 males with an average age of 42.5 years(rang,30 to 56 years).The involved levels included C3、4 in 12 cases,C4、5 in 8,combined C3、4 and C4、5 in 4,and combined C4、5 and C5、6 in 3.Surgical methods included anterior discectomy and fusion with interbody bone grafting and internal fixation with plate or fusion with cages.JOA score system was used for the evaluation of neurological function.[Result]All the patients were followed for 43 months(30 to 60 months).Satisfactory results were achieved in most of the patiens 3 months after surgery.At latest follow-up,complete relief of the preoperative complaints was obtained in 22 patients with incomplete relief in 4 and no obvious improvement in 2.Neurological function was improved from preoperative JOA 10.10 to postoperative JOA 14.90 with satistically significance.Adjacent unstable segments proximal to fuxion level were noted in three cases but with no recurrence of the preoperative symptoms.[Conclusion]For properly selected patients with vertigo secondary to unstable cervical spine,satisfactory medium-term clinical outcomes can be achieved appropriate surgical methods.

Objective To evaluate the clinical efficacy and safety of bicyelol tablets in treatment of hepatitis B patients infected with YMDD mutation of HBV. Methods Sixty-eight chronic hepatitis patients infected with HBV YMDD mutants and 100 patients with non-mutants HBV were enrolled in the study. All patients received bicyclol tablets orally 150 mg/d, t. i. d, for 24 weeks. Clinical symptoms, signs and adverse effects were observed, and the blood routine, liver function tests, serum HBV markers and HBV DNA loads were examined at 12th and 24th week of the study, Results After treatment for 24 weeks, the normalization rates of ALT and AST in mutant group were 79.4% ( 54/68 ) and 70. 6% (48/68) ; 11 ( 16. 2% ) patients were markedly effective and 14 (20. 6% ) were effective. Clearance rates of HBeAg and HBV DNA were 27.9% ( 17/61 ) and 17.6% ( 12/68 ), while the seroconversion rate of HBeAg was 14. 7% (9/61). The differences of the above indexes were not statistically significant between mutant group and non-mutant group. Conclusion Bicyciol can both protect liver functions and inhibit virus replication in patients infected with HBV YMDD mutants.

Objective To study the effects of linderae on alcoholic-induced acute liver injury in SD rats. Methods Forty SD rats were randomly divided into normal group, model group, biphenyl double ester group,and radix lin-derae group. The levels of serum alanine aminotransferase ( ALT) ,aspartate aminotransferase ( AST) were detected with routine laboratory methods using an autoanalyzer. Histopathological changes were assessed by HE. The activities of superoxidedismutase ( SOD) and the level of malondialdehyde ( MDA) in liver homogenates were measured by spectrophotometry. The expression of interleukin-1β( IL-1β) ,nuclear factor-κB( NF-κB) , and tumor necrosis fac-tor-α ( TNF-α) in the liver were analyzed by immunohistochemistry. Results Compared with the normal group, the levels of serum ALT, AST in rats treated with radix linderae were significantly decreased. The activity of serum and liver tissue SOD was significantly increased. Furthermore, the levels of IL-1β, NF-κB and TNF-αwere signifi-cantly decreased after treatment with radix linderae ( P<0. 05 ) . Conclusion The results of our study indicate that extracts from radix linderae alleviate alcoholic liver injury, in part maybe by improving the SOD activity of liver tis-sue and by increasing the antioxidant capacity. Meanwhile, the ability of linderae to reduce proinflammatory cyto-kine has a direct protective effect on hepatocytes.
