Objective To observe the effects of electro-acupuncture on the expression and inhibition of DNA binding protein 2 (Id2) and myelin basic protein (MBP),and to explore the mechanism of remyelinization after compressive spinal cord injury (CSCI) in rats.Methods Fifty-four SD rats were randomly divided into a control group and a treatment group,and each was further subdivided into 3 time point subgroups:3,7 and 14 days.There were 9 rats in each subgroup.The CSCI models were made with a self-designed method.The acupuncture points Jiaji (EX-B2),bilateral Zusanli (ST36) and Taixi (KI3) were selected for treatment.Electro-acupuncture (continuous wave,2 Hz,1.5 V)was applied to the bilateral Zusanli (ST36) and Taixi (KI3) points.The control group received the injury but no treatment.The changes in the ultrastucture of the nerve fibers＇ white matter were de-termined by transmission electron microscopy (TEM).The alterations in the expression of MBP and Id2 were observed by double labeled immunofluorescence and Western blotting on the 3rd,7th and 14th day after the injury.Results TEM showed that the myelin sheaths in the control group had degenerated,swollen,and even broken down after CSCI.Changes to the myelin sheaths in the treatment group were milder than those in the control group.The immunofluorescence results showed the amount of Id2-immunoreactive oligodendrocytes in the control group to be (20 ±2) on the 3rd day after CSCI,becoming (16 ± 1) on the 14th day.The differences among the 3 control subgroups were not statistically significant.The amount of Id2-immunoreactive oligodendrocytes in the treatment group was (13 ± 1) on the 3rd day,reaching a minimum the 14th day.The differences among the 3 treatment groups were statistically significant.The differences compared with the control group at the same time points were also statistically significant.Western blotting showed that the expression of Id2 in the contrast and treatment groups was (1.12 ±0.12) and (0.67 ±0.01) respectively on the 3rd day after CSCI,and both decreased with time.The expression of Id2 in both groups reached their minima ((0.86 ±0.02) and (0.25 ±0.01) respectively) on the 14th day.The difference between the treatment groups and the contrast group was statistically significant at each time point.The expression of MBP in the contrast and treatment groups at day 3 was (0.44 ± 0.02) and (0.67 ± 0.04) respectively,and these increased with time.The expression of MBP in both groups peaked at the 14th day (at (0.95 ± 0.04) and (1.74 ± 0.09) respectively).These differences were again statistically significant.Conclusion Electro-acupuncture can regulate the expression of Id2 and MBP after CSCI.The down-regulation of Id2 which controls MBP negatively and the up-regulation of MBP may contribute to remyelination in the injured spinal cord.

Objective To observe the effect of the electroacupuncture ( EA) on the expression of cyclin-de-pendent kinase 5 ( Cdk5 ) in rats with muscle contusion and to explore its mechanism. Methods Thirty-two Sprague-Dawley rats were randomly divided into a normal group of 4, a model group of 4, a natural recovery group ( NR) of 12 and an EA group of 12. All except those in the normal group had acute skeletal muscle contusion induced through a heavy blow. The EA group was treated with 15 minutes of EA daily beginning 48 h after the injury while the other rats received no EA. The model group was sacrificed 24 h after modeling, and rats from the NR and EA groups were sacrificed on the 7th, 14th and 21st day after the modeling to collect tissues. Hematoxylin eosin ( HE) staining, Western blotting and quantitative real-time fluorescence PCR were used to observe any histological changes, as well as Cdk5 protein and mRNA expression. Results The HE staining showed that the other 3 groups displayed larger a-mounts of muscle fiber fracture, dissolution and inflammatory cell invasion than was observed in the normal group. Compared with the NR group, quicker recovery was seen in the EA group as evidenced by faster muscle satellite cell proliferation and more new muscle fiber generation. The average Cdk5 protein expression in both the NR and EA groups was higher than in the normal group, and that of the EA group was significantly lower than that of the NR group. Conclusions Muscle contusion can increase Cdk5 expression in skeletal muscles, at least in rats. EA can promote the restoration of skeletal muscle function, probably by inhibiting CDK5 protein and mRNA expression.

Objective To investigate correlation between demyelination and caspase-12 expression alteration after compressed spinal cord injury (CSCI) so as to discuss mechanism of demyelinating lesion after CSCI.Methods Seventy-five adult SD rats were randomly divided into five groups,ie,normal group,control group,compression 1 d,3 d and 7 d groups,with 15 rats per group.Models of spinal cord compression were established with a self-made device.Ultrastructure of the demyelinated nerve fibers was observed by electronic microscope and oligodendrocyte apoptosis was detected by TUNEL staining and double labeling immunofluorescence.Immunoblotting was used to defect caspase-12 that was related to cell apoptosis.Results Demyelination of nerve fiber occurred after CSCI and was aggravated with time.Apoptosis of oligodendrocytes was found after CSCI,and showed significant difference between compression 7 d group and normal group (P ＜ 0.05).Caspase-12 was also upregulated with extension of compression time.Conclusion Caspase-12 mediating oligodendrocyte apoptosis is one of the mechanisms of nerve fiber demyelination after CSCI.

Objective To investigate the role of demyelination and the alteration of chondrotin sulfate proteoglycan (CSPG,NG2) expression after compression injury of the spinal cord (CSCI).Methods Seventy-five adult Sprague-Dawley rats were randomly divided into a normal group,a sham-operation group,a CSCI 1 day group,a CSCI 3 day group,and a CSCI 7 day group.There were 15 rats in each group.The injuries in the CSCI groups were inflicted using a technique devised in our laboratory.Basso-Beattie-Bresnahan (BBB) neurological function assessment was used to assess the rats' motor function,osmic acid staining and transmission electronic microscopy (TEM)were used to observe any pathological changes of myelinated nerve fibers in the white matter at 1,3 and 7 days after CSCI.The amount of myelinated nerve fibers in the posterior funiculus of the spinal cord and the ratio of myelin sheath thickness to axon diameter (the G-ratio) were calculated.Any alteration in NG2 expression was observed by Western blotting.Results The average neurological function assessment scores in the CSCI groups were (1.23 ±0.45),(0.65 ± 0.35) and (0.00 ± 0.00) respectively.Compared with the normal group (21.00 ± 0.00) and the sham operation group (21.00 ± 0.00),the differences were all statistically significant.The rats' motor function deteriorated gradually with time after the CSCI.Osmic acid staining showed that the white matter was intact in the normal and sham groups.After being compressed the myelinated nerve fibers became swollen,degenerated and broke down.The amount of myelinated nerve fibers in the normal group,the sham operation group and the three CSCI groups was (2771 ± 108),(2675 ± 199),(2403 ± 161),(1708 ± 70) and (8 10 ± 95) respectively.The amount of myelinated nerve fibers decreased in the CSCI groups and reached a minimum on the 7th day.The difference was statistically significant.The TEM quantity analysis showed that the G-ratios in the normal,sham operation,and CSCI 1 day,3 day and7 day groups were (18.10±0.4),(17.70±1.0),(6.69 ±0.8),(5.73 ±0.4) and (4.95 ±0.5) respectively.Compared with the normal and sham operation groups,the G-ratios in the 3 CSCI groups were lower and reached their minimum on the 7th day after injury.The difference was statistically significant.TEM observation showed that the axons and myelin sheaths were intact in the normal and sham groups.After CSCI the axons became swollen and cell organelles in the axoplasm degenerated and decreased.The layers of myelin sheath shrank,folded and even wrinkled,which had an onion-like appearance.The oligodendrocytes exhibited chromatin condensation.Macrophages showed infiltration.Western blotting showed that the expression of NG2 in the CSCI groups reached a maximum on the 1st day after injury and then decreased with time.The expression of NG2 in the CSCI groups was higher than in the normal and sham groups,and the difference was statistically significant.Conclusion Demyelination occurs after CSCI-the amount of myelinated nerve fibers decreases and neurological deficits increase with time.The expression of NG2 was associated with changes in the myelin sheaths after CSCI and contributed to recovery of the myelin sheath through proliferation and differentiation to oligodendrocytes and perhaps other kinds of cells.

Objective To explore the epidemiological status of abnormal glucose metabolism and its influential factors among middle and aged population with hypertension in Chengdu area. Methods In 2008, after adopting the methods of stratified cluster sampling, the authors investigated 4685 subjects of the middle and aged population between the age of 40-79 in Chengdu urban and rural area by checking blood pressure and oral glucose tolerance test (OGTY). Patients with previously known diabetes mellitus (DM) were only asked to perform fasting glucose and to carry out a questionnaire. Comparison of the prevalence rates of abnormal glucose metabolism in hypertensive and non-hypertensive subjects was carried out. The prevalence rates of isolated impaired glucose tolerance (I-IGT) and isolated postprandial hyperglycemia (IPH) among middle and aged subjects with hypertension were acquired and the influential factors of abnormal glucose metabolism among middle and aged subjects with hypertension were analyzed. Results The prevalence rate of abnormal glucose metabolism in the hypertensive subjects was obviously higher than that in the non-hypertensive subjects; without using OGTT, 72.9% of the pre-diubetic and 54. 4% of the new diagnosed DM patients would remain undiagnosed if fasting plasma glucose detection was used alone. Age, diabetic history of first degree relatives ,overweight or obesity were the risk factors for the development of abnormal glucose metabolism among middle and aged male subjects with hypertension in Chengdu area. Exercise training and high education level were the protective factors. Age, diabetic history of first degree relatives,abdominal obesity and hypertriglyceridemia were the risk factors for the development of abnormal glucose metabolism among middle and aged female subjects with hypertension in Chengdu area. Conclusions More than 50% of middle and aged subjects with hypertension in Chengdu area has accompanying abnormal glucose metabolism. OGTT easily discloses the abnormal status and should be a routine procedure in the diagnosis of pre-diabetes or DM in such population. Appropriate exercise, learning diabetes-related knowledge to take reasonable lifestyle, and intervention of metabolic factors such as overweight or obesity are advised. Abdominal obesity and hypertriglyceridemia play important roles in leading to abnormal glucose metabolism among middle and aged population with hypertension.

Objective To observe the effects of massage on inflammation,oxidative stress and autophagy during the repair of acute contusion of skeletal muscles so as to explore its biological mechanisms.Methods Forty-two adult Sprague-Dawley rats were randomly divided into a control group (n =6),a model group (n =18),and a treatment group (n =18).Acute contusion of the gastrocnemius muscles of the rats in the model and treatment groups was inflicted using a home-made impactor.Beginning forty-eight hours later,15 minutes of massage was administered daily for two weeks.After one,7 and 14 days of the massage treatment,the injured gastrocnemius was resected from 6 rats of both the model and treatment groups.Morphological changes were observed using haematoxylin and eosin (HE) staining.The serum content of tumor necrosis factor alpha (TNF-α),interleukin1β (IL-1 β),C reactive protein (CRP) and prostaglandin E2 (PGE2) were detected using enzyme-linked immunosorbent assay (ELISA).The serum content of superoxide (SOD) and malondialdehyde (MDA) were detected using spectrophotometry.The expression of microtubule-associated protein 1 light chain 3 (LC3),Bcl-2 homeodomain protein Beclin1 and ubiquitin binding protein P62 were detected using Western blotting.Results The HE staining showed more significant collapse and swelling of cells in the model group than in the control group at each time point.New muscle cells were observed at days 7 and 14 in the model group.At each time point,significantly better recovery was observed in the treatment group compared to the model group,with more new muscle cells and better cell morphology.According to the ELISA results,a significant increase in serum pro-inflammatory factors occurred in the model group compared to the control group and compared to the treatment group after one day and 7 days of treatment.The average serum content of SOD and MDA in the model group was significantly higher than in the control group,while the average serum content of SOD in the treatment group was significantly higher than in the model group and that of MDA was significantly lower.Western blotting showed a significant decrease in LC3 (Ⅱ/Ⅰ) and Beclin1,as well as a significant increase in P62 in the model group at each time point compared with the treatment group and the controls.Conclusion Inflammation and oxidative stress increase significantly in a skeletal muscle after injury,but autophagy decreases significantly.Massage can effectively reduce the inflammatory response and oxidative stress and promote autophagy,which leads to quicker repair of skeletal muscles.
