Objective:To evaluate the change of sleep-wake rhythm after extracorporeal circulation (ECC) in New Zealand rabbits,and to explore the role of clock genes in sleep-wake rhythm disorder by ECC.Methods:A total of 54 New Zealand rabbits were randomly divided into 3 groups:a normal group (Group N),a sham group (Group S) and a model group (Group ECC).Electrocorticogram (ECOG),electroophthalmogram (EOG) and electromyogram (EMG) were respectively recorded by multipurpose EEG recorder,and the sleep-wake rhythm was also recorded.The mRNA and protein expressions of period1 (Per1) and cryptochrome1 (Cry1) were detected by semiquantitative reverse transcriptase PCR (RT-PCR) and Western blot in pineal gland of rabbits.The differences between the 3 groups were compared.Results:1) Compared with the Group N and Group S at 24,48 h respectively,the total amount of sleep (TAS),light time,slow wave sleep (SWS) in the Group ECC at 24,48 h were significantly reduced (all P＜0.05),and the proportion of light sleep increased (all P＜0.05),the proportion of SWS decreased (all P＜0.05);2) Compared with the Group N and Group S,the expression of Per1 mRNA in the Group ECC at 24,48 h and Cry1 mRNA at 24 h significantly increased (all P＜0.05);3) Compared with the Group N and Group S,the expression of Perl protein in the Group ECC at 48 h and Cry1 protein at 24 h significantly increased (all P＜0.05);4) In the Group ECC,the sleepwake rhythm disorder and clock genes expression were ameliorated at 72 h after surgery.Conclusion:ECC can cause sleep-wake rhythm disorder in New Zealand rabbits,which may be related to the abnormal expression of Per1 and Cry1,and their transcription proteins.

Objective: To compare the efficacy of Tuina (Chinese therapeutic massage) plus physical agents and physical agents alone for lateral collateral ligament injury of ankle in gymnasts, and to explore the feasibility of Tuina for injury intervention in competitive athletes.Methods: A total of 64 gymnasts with types Ⅰ-Ⅱ lateral collateral ligament injury of ankle were selected and divided into a control group and an observation group according to a full analysis set based on the intention-to-treat principle, with 32 cases in each group. Patients in the control group received ultrasound and microwave treatment, while those in the observation group received additional Tuina manipulations. The efficacy was evaluated by total effective rate, visual analog scale (VAS) score, and American Orthopedic Foot and Ankle Society ankle-hindfoot scale (AOFAS-AHS) score. Results: The total effective rate was 96.9％ in the observation group and 90.6％ in the control group. There was no statistical difference in the total effective rate between the two groups (P>0.05). The markedly effective rate was 75.0％ in the observation group and 46.9％ in the control group. The markedly effective rate in the observation group was higher than that in the control group (P<0.05). After treatment, the VAS scores of both groups showed a downward trend, and there were statistical differences between different treatment time points in the same group (P<0.05). After one and three months of treatment, the VAS scores of the observation group were lower than those of the control group (P<0.05). There were statistical differences in the AOFAS-AHS score before and after treatment within the same group (P<0.05). After one month of treatment, there was no statistical difference in the AOFAS-AHS score between the two groups (P>0.05). After three months of treatment, the AOFAS-AHS score in the observation group was higher than that in the control group, indicating statistical significance (P<0.05). There was an interaction between time and group (P<0.05). Conclusion: Tuina plus physical agents can improve the symptoms of lateral collateral ligament injury of ankle in gymnasts. This combined treatment is superior to physical agents alone in relieving pain and improving joint functions. Therefore, Tuina plus physical agents can be used as a treatment for lateral collateral ligament injury of ankle in gymnasts.

Objective To evaluate the effect of ulinastatin on the expression of metabotropic glutamate receptor Ⅱ ( mGluRⅡ) during cerebral ischemia-reperfusion ( I∕R) in rats. Methods Forty-eight male Sprague-Dawley rats, aged 6-8 weeks, weighing 230-280 g, were divided into 3 groups ( n=16 each) by a random number table method: sham operation group (S group), cerebral I∕R group (I∕R group) and ulinastatin group ( U group) . The model of cerebral I∕R injury was established by occluding the right middle cerebral artery using a nylon thread with a rounded tip inserted into internal carotid artery and advanced cranially until resistance was met. Middle cerebral artery occlusion was maintained for 2 h followed by 24-h reperfusion. Ulinastatin 100000 U∕kg was injected via the tail vein immediately after onset of reperfusion in group U. The neurological deficit score ( NDS) was assessed after 24 h of reperfusion. The rats were then sacrificed, and brain tissues were obtained for determination of brain infarction ( by TTC staining) , expression of IκB-α in cerebral ischemic penumbra ( by Western blot) and expression of mGluRⅡ in cerebral ischemic penumbra ( by immunofluorescent staining) . The percentage of cerebral infarct vol-ume was calculated. Results Compared with S group, the NDS and percentage of cerebral infarct volume were significantly increased, the expression of mGluRⅡ in cerebral ischemic penumbra was up-regulated, and the expression of IκB-α in cerebral ischemic penumbra was down-regulated in I∕R and U groups ( P<0. 05). Compared with I∕R group, the NDS and percentage of cerebral infarct volume were significantly de-creased, the expression of mGluRⅡ in cerebral ischemic penumbra was down-regulated, and the expres-sion of IκB-α in cerebral ischemic penumbra was up-regulated in U group ( P<0. 05) . Conclusion The mechanism by which ulinastatin mitigates cerebral I∕R injury may be related to inhibiting the expression of mGluR Ⅱ in cerebral ischemic penumbra of rats.

Objective: To observe the efficacy of herbal cake-partitioned moxibustion for lumbar disc herniation (LDH) due to kidney deficiency and blood stasis and observe the influence of this method on lumbar functions and inflammatory factors in patients with this condition. Methods: A total of 120 LDH patients who met the inclusion criteria were randomly divided into three groups, including a herbal cake-partitioned moxibustion group, a flour cake-partitioned moxibustion group, and a Western medication group, with 40 patients in each group. The patients in the Western medication group were treated with diflunisal tablets, 0.5 g per dose, 2 doses a day. Those in the herbal cake-partitioned moxibustion group were treated with additional herbal cake-partitioned moxibustion group at Back-Shu Points and Jiaji (EX-B2) Points once a day. Those in the flour cake-partitioned moxibustion group were treated with the same methods as in the herbal cake-partitioned moxibustion group, except that the herbal cake was replaced by a flour cake. All the patients were treated for 10 d. After treatment, the scores of the visual analog scale (VAS) and Japanese Orthopaedic Association (JOA) and the changes of the interleukin (IL)-6, tumor necrosis factor (TNF)-α, and substance P (SP) levels were observed, and the efficacy was evaluated. Results: After treatment, the VAS score and the levels of IL-6, TNF-α, and SP were lower than those before treatment, and the JOA score was higher than that before treatment in the three groups, indicating intra-group statistical significance (P<0.05). The VAS score and the levels of IL-6, TNF-α, and SP of the herbal cake-partitioned moxibustion group were lower than those of the flour cake-partitioned moxibustion group and the Western medication group, while the JOA score of the herbal cake-partitioned moxibustion group was higher than that of the other two groups, indicating inter-group statistical significance (P<0.05). The total effective rate of the herbal cake-partitioned moxibustion group was 92.5％, higher than that of the flour cake-partitioned moxibustion group (80.0％) and the Western medication group (72.5％), indicating inter-group statistical significance (P<0.05). Conclusion: On the basis of Western oral medication, additional herbal cake-partitioned moxibustion can alleviate the pain and improve the lumbar functions in patients with LDH due to kidney deficiency and blood stasis. The efficacy of the integrated method is better than that of either flour cake-partitioned moxibustion or Western medication alone, which may be related to the reduction of serum inflammatory factors.
