ObjectiveTo observe the effectiveness of collagen sponge for reducing volume of drainage after surgery for lumbar spinal stenosis. MethodsOne hundred and eighty-six patients who suffered from lumbar spinal stenosis were divided into two groups by random digits table method. The test group(96 cases) used collagen sponge to cover dura mater before placing drainage tube,the control group (90 cases) was treated without collagen sponge. The volume of drainage at 1,12,24 h after surgery were observed, the blood routine test was carried out at before and 48 h after surgery and the volume and ratio of blood transfusion after surgery was also measured and compared between the two groups. ResultsThe volume of drainage were significantly decreased in the test group compared with the control group at 1,12,24h after surgery [( 106.11 ± 20.02 ) ml vs. ( 127.02 ± 25.09) ml, (236.12 ± 34.06) ml vs. (327.31 ± 51.21 )ml, (355.16 ± 49.03 ) ml vs.( 506.36 ± 85.29 ) ml](P ＜ 0.05 ). The volume and the ratio of blood transfusion in the test group were ( 176.27 ± 21.37) ml and 10.42％(10/96) ,which were greatly lower than those in the control group[(445.94 ±24.56) ml and 32.22％ (29/90)](P ＜0.05). The number of RBC and the concentration of Hb were (2.96 ± 0.45 ) × 1012/L and ( 106.75 ± 7.30) g/L, differently in the test group at 48 h after surgery,which were increased significantly compared with the control group[(2.35 + 0.57) × 1012/Land (90.45 ± 5.10) g/L](P ＜ 0.05 ). ConclusionsCollagen sponge provides rapid ,effective and durable hemostasis and decreases the leak of cerebrospinal fluid after surgery for lumbar spinal stenosis. It can be used as an effective and economic method to reduce the volume of drainage after surgery.

BACKGROUND:Nano-hydroxyapatite/polyamide artificial bone has good biocompatibility and strong tissue binding force, which exerts a significant role in the recovery of neurological function. OBJECTIVE: To investigate the clinical effect of nano-hydroxyapatite/polyamide artificial bone in anterior cervical fusion. METHODS: Ninety patients with cervical spondylosis and traumatic dislocation of the cervical spine were randomized into observation group and control group. Patients in the two groups underwent nano-hydroxyapatite/polyamide artificial bone and autologous iliac bone implantation, respectively. Surgical condition, Japanese Orthopaedic Association score, vertebral height loss and bone fusion rate were compared and analyzed at different time after implantation. RESULTS AND CONCLUSION:There were no significant differences in surgical time, out of bed time, postoperative hospitalization time between the two groups (P > 0.05), but the intraoperative blood loss was significantly lower in the observation group than the control group (P < 0.05). Japanese Orthopaedic Association scores were significantly increased in the two groups at 3 and 6 months after operation and at last folow-up than before (P < 0.05), but there was no difference in the Japanese Orthopaedic Association score between the two groups (P> 0.05). The vertebral height loss and bone fusion rate had no difference between the two groups at 6 months after operation and at the last folow-up (P > 0.05). No adverse effects occurred in the two groups. These findings indicate that nano-hydroxyapatite/polyamide artificial bone has good clinical effects in anterior cervical fusion, and the treatment effect is equivalent to autologous iliac bone graft.

Amblyopia greatly affects the physical and mental development of children. Acupuncture is effective for amblyopia, though its mechanism remains unclear. This article summarized the mechanism of acupuncture treatment of amblyopia from the perspectives of morphology of neurons in visual cortex, visual electrophysiology, and molecular biology, etc. It was found that acupuncture may treat amblyopia through repairing the morphological and ultrastructural damages of neurons in visual cortex, promoting the electrical activities in visual pathway and visual cortical neurons, and modulating the synthesis and expression levels of factors involved in visual system. Nevertheless, further studies are required to unveil the mechanism of acupuncture treatment of amblyopia.

Objective To assess the effects of non-pharmacological means physical exercise and ketogenic diet on neurobehavior of developmental rats with recurrent seizures.Methods Chinese and English literatures from PubMed,EMBASE,OVID MEDLINE,Chinese Biomedical Literature Database (CBM),Academic literature database,Wan fang database,Chongqing Chinese Science and Technology Periodical Database (the time of building a databaseAugust 2012) by the computer were researched.Those articles according to inclusion and exclusion criterias were inclusived qualified randomized controlled studies and their quality were evaluated.Then the Meta-analysis was performed by Rev Man 5.1.Results 1.Physical exercise intervention:Six articles were included according to the inclusion criterias,2 in Chinese,4 in English.The differences among recurrent-seizure and non-exercise(RS + NE) group,recurrent-sei-zure and physical exercise (RS + PE) group,non-seizure and non-exercise(NS + NE) group,non-seizure and physical exercise(NS + PE) group were respectively compared.There was significant difference in escape latency between RS +NE group and RS +PE group(WMD =13.96,95％ CI:8.46-19.46,P ＜0.000 01).There was no significant difference in escape latency between NS + NE group and NS + PE group(WMD =-1.53,95％ CI:-6.77-3.70,P =0.57).2.Ketogenic diet intervention:Five articles were included,2 in Chinese,3 in English.The differences among non-seizure and normal diet (NS + ND) group,non-seizure and ketogenic diet (NS + KD) group,recurrent-seizure and normal diet (RS + ND) group,recurrent-seizure and ketogenic diet(RS + KD) group were respectively compared.(1)There were significant differences in scores and escape latency between NS + ND group and NS + KD group (WMD =18.82,8.80,95 ％ CI:15.64-22.01,1.48-16.12,P ＜ 0.000 01,P =0.02).(2) There was no significant difference in scores and escape latency between RS + ND group and RS + KD group(WMD =-23.72,7.16,95％ CI:-98.55-51.11,-0.52-14.84,P =0.53,0.07).There was significant difference in discharge threshold between RS + ND group and RS + KD group (WMD =34.57,95 ％ CI:16.46-52.69,P =0.0002).Conclusions This study suggested that non-pharmacological means such as physical exercise and ketogenic diet would protect the brain from damages of irecurrent seizures.Additionally,ketogenic diet may be bad to the neuro-behavior of normal rats.There had no evidence to indicate the relationship between physical exercise and normal rats neurobehavior.

Objective To investigate the impairment and the effect factors of encoding of episodic memory in patients with cerebral infarction. Methods 112 cases cerebral infarction patients and 115 healthy elders as controls were tested for episodic memory encoding with episodic pictures accomplished in computer, and compare the differences of encoding of episodic memory between the two groups. Results The remember indexes ( REM )of encoding memory test in patient group was significantly lower than that in control group( (70.81 ± 6.08 )vs (84.67 ± 4.49), P ＜ 0.01 ). The REM in patients with different impaired areas was significantly different ( (65.88 ± 5.73 ), (68.92 ± 4.65 ), (73.39 ± 6.20), ( 73.53 ± 3.44), P ＜ 0. 01 ). The REM in frontal lobe infarction group was significantly lower than that in temporal lobe infarction group (P ＜ 0.05 ), and in temporal lobe infarction group was significantly lower than that in basal ganglia infarction group and corona radiate infarction group (P＜0.05, P＜0. 01). The REM in cortex infarction group was significantly lower than that in under cortex group ( ( 67.37 ± 5.40 ), ( 73.46 ± 4.99 ), P ＜ 0.01 ). The REM in small cerebral infarction group was significantly higher than that in large cerebral infarction group( (72.67 ±4.47 ), (67.56 ± 6.18 ), P＜0.01 ). The size of cerebral infarction diameter was related with the REM( r= -0.39, P＜0. 01 ). The REM among control group,infarction with atrophy group, and infarction without atrophy group were significantly different( (67.03 ± 6. 17 ),( 72.84 ± 5. 00 ), ( 84.67 ± 4.49 ), P ＜ 0. 01 ). The REM in infarction with atrophy group was significantly lower than that in infarction without atrophy group and control group( both P＜0.01 ) ,The REM in infarction without atrophy group was significantly lower than that in control group (P ＜ 0.01). Conclusion The encoding of episodic memory was impaired in cerebral infarction patients. The infarction parts,size of infarction area and atrophy was related with the impairment of encoding of episodic memory.
