BACKGROUND: Peripheral facial paralysis is treated at present only with traditional traumatic methods, such as acupuncture, moxibustion,needling with physical therapy, point-injection, thread burial therapy,scraping therapy, etc. Those methods do not act directly on the lesion of facial nerve and they are long in duration of treatment and low in curative rate. The constant magnetic aerobic atruamatic method along meridian just makes up the shortcoming of the traditional therapies.OBJECTIVE: To observe the therapeutic effects of constant magnetic aerobic atruamatic method along meridian on treatment of peripheral facial paralysis.DESIGN: Case analysis.SETTING: Department of Facial Paralysis, College of Stomatology, Fourth Military Medical University of Chinese PLA.PARTICIPANTS: Totally 1 500 cases of first diagnosed peripheral facial paralysis were employrd in 18 provinces and autonomic regions in China from June 1998 to June 2004, of which, 935 cases were male and 565 cases female. Of 103 cases were aged varied from 1.5 to 19 years, 1 105 cases from 20 to 50 years and 292 cases from 51 to 74 years. Of 672 cases were left palsy and 828 cases were right palsy. The duration of sickness was varied from 1 day to 40 years.METHODS: Constant magnetic aerobic therapy for 20 minutes was applied on facial-palsy effective points for all of cases [No.1 point: in the depression inferior to mastoid process behind ear lobe on the affected side,corresponding to the mastoid foramen, from which, the facial nerve emerges. No.2 point: on the arch top of mastoid process behind ear lobe on the affected side. No.3 point: about 3.33 cm (1 cun) above No.1 point. No.4: in the conjunction between the point about 0.5 cm posterior to the external auricular tract and the one 0.5 cm inferior to helix cms. No.5 point:about 1 cun anterior to ear apex. No.6 point: on the top of the upper border of helix on the affected side] and supplementary points [Qianzheng (Extra),Dicong (ST 4), bilateral Hegu (LI 4)], once per day, 10 days makes one course. There were a couple of days at interval between two courses, totally two courses were required. Point and oxygen therapies were applied simultaneously. Oxygen therapy: 20 minute/time, once per day, 10 days made one course, at the volume of oxygen 2-4 L/minute. Evaluation of therapeutic effects: It was to compare the changes between the affected side and healthy side in forehand wrinkles, frowning, closing eyes, whistling, blowing and smiling and the changes between two sides in nasal labial groove and philtrum during showing the teeth and at static state. Comparison of bilateral muscularis function of healthy people and patients were obtained with the six-point and four-line measurement.MAIN OUTCOME MEASURES: Results of evaluation on clinical therapeutic effects.RESULTS: Totally 1 500 cases of peripheral facial paralysis entered result analysis, no dropped out case. After 20 days treatment, 1 385 cases (92.33%) were recovered, 92 cases (6.13%) appeared significant effect, 22cases (1.74%) were improved and 1 case (0.07%) was no effect. The total effective rate was 99.93%.CONCLUSION: Constant magnetic field in combination with oxygen therapy is characterized as no pain, no trauma, no cross infection and no second injury of facial nerve, safe and convenient operation, short duration of treatment and high curative rate. It improves remarkably the symptoms of facial paralysis and recovers facial function.

Objective To investigate the effect of Lokomat gait training rehabilitation robot on joint motion and lower limb function in hemiplegic patients after stroke.Methods Forty hemiplegic patients after stroke were randomized equally into a robotic group and a control group (20 cases in each group).The robotic group received robotic rehabilitation therapy in addition to routine rehabilitation training,while the control group was only given instructions for routine rehabilitation training.All the patients were assessed at the beginning of the training and at the end of 4,8 and 10 weeks of treatment.The Fugl-Meyer Assessment of lower extremities (FMA),range of motion (ROM) in hip and knee,force and tone of bilateral hip/knee flexors and extensors were used to evaluate stepping function before training,and after 4,8 and 10 weeks of treatment.Results There was no significant difference between the 2 groups with regard to FMA scores,the ROM in hip and knee,as well as force and tone of bilateral hip/ knee flexors and extensors (P ＞ 0.05).After treatment,the robotic group was significantly improved with all the evaluation indexes when compared to its baseline values (P ＜ 0.05).It was also shown that the robotic group improved to a significantly greater extent than the control group (P ＜ 0.05).Pearson's correlation analysis demonstrated a positive relationship between the ROM of knee or hip and lower limb function (P ＜ 0.05).Conclusions The Lokomat gait training rehabilitation robot can improve the lower extremities functions,as indicated by increase of ROM and muscle strength as well as decrease in muscle spasticity in hemiplegic patients after stroke.

Objective: To explore the coping strategies of students of military medical university, and the relationship between coping strategies and mental health. Methods: 4786 students of military medical university were assessed with the Simplified Coping Style and SCL-90. Results: 30～40% of the student chose active strategies when facing stresses. Fewer students adopt negative strategies (2～38%). The SCL-90 score of the students of military medical university were lower than students of other military schools. Positive coping strategies were associated with less SCL-90 score (fewer somatic and mental discomfort).Conclusion:Coping strategies are associated with mental health in student of military medical university.

Objective: To explore the coping strategies of the elderly with Impaired Glucose Regulation(IGR), to compare the differences of coping strategies among the groups of different prognosis and to provide some advice on psychological intervention. Methods: Fasting Plasma Glucose (FPG)and two-hour postprandial Plasma Glucose of OGTT(OGTT2hPG)of 220 old persons with IGR were tested, and they were assessed by TCSQ. Results: 27.73%～78.64% of old people with IGR chose active strategies when facing stress, 4.09%～18.18% of them adopted negative strategies. There were no significant differences of coping strategies among the groups of different prognosis. Conclusion: It was better to pay more attention to those who mainly selected negative strategies in psychological intervention on the elderly with IGR.

Objective:To investigate the effect of body mass index (BMI) on setup errors in intensity-modulated radiotherapy for cervical cancer and explore the optimal position for patients with different BMI without taking into account the rotation error and the changes in target area and adjacent organs.Methods:A total of 90 patients were divided into three groups according to their BMI: light weight group (BMI≤18.4 kg/m 2), normal weight group (18.5 kg/m 2≤BMI≤23.9 kg/m 2) and overweight group (BMI≥24 kg/m 2). Thirty patients were assigned into each group including15 patients in the supine position and 15 patients in the prone position. In total, 2 250 sets of CBCT scan data of 90 patients were obtained. The setup errors were recorded and analyzed in each group. The margins of the optimal position were calculated according to the formula of M PTV=2.5+ 0.7. Results:When BMI was not taken into account, there was no significant difference in the setup errors between the supine and prone positions in the x, y and z directions (all P>0.05). When BMI was considered, the setup error in the supine position were significantly smaller than those in the prone position in the x and y directions in the light weight group, whereas there was no significant difference in the setup errors between the supine and prone positions in the z direction ( P>0.05). The corresponding M PTV in the supine position was 4.76, 4.27 and 5.73 mm, respectively. In the normal weight group, there was no significant difference in the setup errors between the supine and prone positions in the x and y directions (both P>0.05), whereas the setup error in the prone position was smaller than that in the supine position in the z direction. The corresponding M PTV in the prone position were 6.42, 10.21 and 4.91 mm, respectively. In the overweight group, there was no significant difference in the setup errors between the supine and prone positions in the x and z directions (all P>0.05), whereas the setup error in the prone position was smaller than that in the supine position in the y direction. The corresponding M PTV in the prone position were 5.88, 5.26 and 5.32 mm, respectively. Conclusions:Without taking into account the rotation error and the changes in target area and adjacent organs, when the BMI≤18.4, the supine position is recommended. When the BMI≥18.5, it is better to choose the prone position.

Objective To review the efficacy of different rehabilitation training on walking locomotion for chronic incomplete spinal cord injury (SCI) by Meta-analysis. Methods PubMed, CNKI, Wanfang Database, and Google academic search were applied to search for clinical trials on chronic incomplete spinal cord injury to review the efficacy of gait training. Meta-analysis was to assess the clinical trials by Rev-Man 4.2. Results Gait training improved the walking speed for chronic incomplete spinal cord injury. The efficacy of partial body weight support treadmill training combined with functional electrical stimulation was confirmed. The efficacy of artificial aided training and robot-aided training remained uncertain. Conclusion Gait training was effective to improve walking ability for chronic incomplete spinal cord injury, but the evidence was insufficient.

Objective To investigate the effect of grape seed proanthocyanidin extract (GSPE) on learning and memory ability after cerebral ischemia/reperfusion injury in rats and its mechanism. Methods 72 healthy male Sprague-Dawley rats were divided into sham group (n=18), model group (n=18) and GSPE groups (20 mg/kg, 200 mg/kg, n=18 for each group). The GSPE groups were administered GSPE orally for 4 weeks, while the sham group and model group were given water 10 ml/kg. Then their middle cerebral arteries were obstructed for 2 h and reperfused, excepted the sham group. 6 rats from each group were selected to test with Morris water maze 12 h, 24 h and 48 h after reperfusion respectively. And then, their brain tissues were stained with Hematoxylin-Eosin staining to observe under optical microscope. The level of superoxide dismutase (SOD) and malondialdehyde (MDA) in the brain tissues were measured. Results Compared with the sham group, the latency significantly prolonged, and the incidence of crossing the area the platform located reduced in the model group in the Morris water maze test, with the SOD decreasing and MDA increasing (P<0.05). Compared with the model group, the latency reduced and the incidence of crossing the area increased in the GSPE 200 mg/kg group, with the SOD increasing and MDA decreasing (P<0.05). Conclusion GSPE may suppress peroxidation after the cerebral ischemia/reperfusion to protect brain and learning and memory ability from injury.

Objective To study the utility of sleep intervention combined with memory training for alleviating dysmnesia in the elderly and provide a basis for improving memory function. Methods A total of 647 community-dwelling elderly people were evaluated using the Pittsburgh Sleep Quality Index (PSQI) and the Rivermead behavioral memory test ( RBMT). One hundred and fifty elderly persons with sleep disorders and dysmnesia were divided into three groups; the control group, the memory intervention group, and the sleep plus memory training group. Sleep quality and dysmnesia were evaluated again after 3 months of intervention. Results Among the 647 elderly people, the incidence of sleep disorders was 38. 8% , and of dysmnesia was 78. 4%. Dysmnesia was significantly more prevalent among subjects who also had sleep disorders. After three months of intervention, instant recall scores had declined in the control group while scores on 7 kinds of memory function had improved significantly in the memory intervention group. Scores on 10 measures of memory and sleep quality improved in the sleep plus memory intervention group. Compared to the control group, scores on 9 kinds of memory improved significantly in the memory intervention group and scores on 11 kinds of memory improved in the sleep plus memory intervention group. Compared to the memory intervention group, scores on 5 kinds of memory had improved significantly in the sleep plus memory intervention group. Conclusions The occurrence of dysmnesia in elderly people is influenced by sleep quality. Memory training can improve their memory function, but sleep intervention combined with memory training is even more effective.

Objective To investigate the effect of treadmill running pretreatment on the expression of CyclinA and CyclinE protein in hippocampus of rats after global cerebral ischemia and reperfusion.Meth-ods 60 healthy male wister rats were randomly divided into control group, model group and experiment group.Global cerebral ischemia reperfusion model was generated by improved four-vessel occlusion as de-scribed according to the description of Pulsinelli's method.Rats in the experiment group were performed treadmill running for 2 weeks before injury.The water maze test was performed at 24 h and 48 h respectively after injury to determine the spatial memory ability of rats.Morphological changes of hippocampus were ob-served by HE staining ( hematoxylin-eosin staining) at 3 h,6 h,24 h,48 h after injury and the expression of CyclinA and CyclinE were detected by immunohistochemical staining.Results Compared with control group,the survival rate of neurons in the model group was significantly decreased at each time point.Morris water maze test showed that the escaping latency of rats in the model group was significantly prolonged( 24 h (24.35±3.99)s,48 h(33.08±5.85)s),and the frequency of crossing the platform was decreased(24 h(6.80 ±0.79),48 h(4.00±0.67)).The expression of CyclinA was increased significantly in the model group ((8.40±0.52)/high view,(11.70±1.06)/high view,(15.50±0.53)/high view,(22.40±0.52)/high view) as well as the expression of CyclinE((20.30±0.48)/high view,(15.20±0.63)/high view,(10.00± 0.82)/high view,(7.70±0.68)/high view) (P<0.05).Compared with model group,the survival rate of neurons in the model group was significantly increased at each time point.Morris water maze test showed that the escaping latency of rats in the experiment group was significantly shorten(24 h(13.21±2.73) s,48 h (24.20±4.66)s),and the frequency of crossing the platform was increased(24 h(9.70±0.95),48 h(6.30± 1.16)).The expression of CyclinA was significantly increased in the model group((10.60±0.84)/high view),(16.70± 0.68)/high view),(24.50±0.53)/high view),(36.20±1.40)/high view) as well as the expression of CyclinE((31.60 ±0.70)/high view),(24.50±0.70)/high view),(16.80±0.63)/high view),(9.10±0.74)/high view) (P<0.05).Con-clusion The treadmill running pretreatment improves the function of spatial memory after global cerebral ischemia and reperfusion,potenlially mediated by regulating the expression for cell cycle proteins,which have a protective effect on cerebral brain tissue.

To explore the stability of Shenkang injection respectively in five different solutions to choose the best com-patibility program and improve the rational drug use. Methods:The pH value, insoluble particles and the content of protocatechuic al-dehyde in Shenkang injection were determined after mixed with five solutions. Results:In the 6-hour mixing, the change order of proto-catechuic aldehyde content was 0. 9% sodium chloride injection> 5% fructose injection> 10% invert sugar injection > 5% dextrose injection> 10% glucose injection, especially in 0. 9% sodium chloride injection, the content was decreased by 20%. The number of insoluble particles was increased after the 2-hour mixing except in 10% invert sugar injection solution, and the increase in the four so-lutions was beyond the requirement in the 2010 edition of Chinese Pharmacopoeia, and the number of insoluble particles in 0. 9% sodi-um chloride injection was the highest with the fastest change. During the experimental process, the pH value was stable. Conclusion:The five solutions show influence on stability of Shenkang injection in varying degrees. Shenkang injection in 0. 9% sodium chloride in-jection is the least stable, which should be used with caution in clinics, while invert sugar injection and glucose injection can be the best choice for Shenkang injection and the mixed solution should be used up in 2h.
