BACKGROUND: Prognosis is determined by degrees of outside force and time of spinal cord compression after spinal cord injury. The former factor cannot be changed, but the latter one can be changed through relieving spinal cord compression as early as possible to promote nervous function recovery.OBJECTIVE: To compare the effect of surgical intervention time on nervous function recovery within 72 hours and 10 to 14 days after cervical spinal cord injury.DESIGN: Randomized controlled and before-after controlled study.SETTING: Department of Spine Surgery of the Second Hospital affiliated to Harbin Medical University.PARTICIPANTS: A total of 32 patients with cervical spinal cord injury were selected from the Department of Spine Surgery of the Second Hospital affiliated to Harbin Medical University from April 1998 to August 2001.All patients were divided into two groups according to randomly alternative criteria. There were 16 cases including 10 males and 6 females in early surgical group (within 72 hours) and there were also 16 cases including 12males and 4 females in delayed surgical group (within 10-14 days).METHODS: Patients in early surgical group were undertaken operation at 72 hours after hospitalization, and patients in delayed surgical group were at 10-14 days after hospitalization. Frankel grade, sensory and motor scores were recorded according to criteria set by American Spinal Injury Association before operation and within 24 months after operation.MAIN OUTCOME MEASURES: ① Sensory and motor scores before and after operation; ② Frankel grade before and after operation.RESULTS: ① Improved level of sensory score (difference before and after operation) was higher in early surgical group than that in delayed surgical group (42.6±20.2, 19.2±19.1, P < 0.01). ② Improved level of motor score (difference before and after operation) was higher in early surgical group than that in delayed surgical group (39.7±17.8, 17.3±18.6, P < 0.01). ③Improved level of Frankel grade in early surgical group was superior to that in delayed surgical group (P < 0.01).CONCLUSION: Nervous function recovery of patients with acute cervical spinal cord injury who were suffered from operation within 72 hours is superior to that of those within 10 to 14 days. Therefore, surgical intervention should be undertaken as early as possible in order to promote nervous function recovery after cervical spinal cord injury.

Persicae Semen (PS), a traditional Chinese medicine, has been widely used for the syndrome of blood stasis in China since the Eastern Han Dynasty. In the present study, we developed an HPLC-UV fingerprint analysis method for the quality control of PS. The HPLC fingerprint was performed on Shimadzu Inertsil C18 column (4.6 mm x 250 mm, 5 microm) at 35 degrees C. The mobile phases were composed of acetonitrile and water using a gradient elution. The flow rate was 1.0 mL x min(-1), and the detection wavelength was set at 210 nm. The fingerprint method was validated according to the Guidelines for Traditional Chinese Medicine Injection Fingerprint, and applied to determine 41 batches representative herbs collected from Xinjiang of China. The chromatographic peaks were characterized by UPLC-Q-TOF-MS, and nine of them were identified by comparison with the literature and/or reference standards. In order to classify and assess the samples, hierarchical clustering analysis and partial least square discriminant analysis were performed based on the common chromatographic peaks, and the samples were geographically classified into two classes, with six chemical compounds as classification markers which were significantly different between the two classes (P < 0.05).
