Objective To observe the effect of electromyographic biofeedback therapy and kinesitherapy on patients with radial nerve injury.Methods 82 patients with radial nerve injury were divided into control group (n=41) and treatment group (n=41). The control group was treated with medcine and acupuncture, while the treatment group received electromyographic biofeedback therapy and kinesitherapy in addition. The radial nerve function was assessed and analyzed by electromyogram (EMG) and motor conduction velocity (MCV) before and after treatment. Results After 12 weeks of treatment, limb motor function, EMG and MCV were better in the treatment group than in the control group (P<0.05). Conclusion Electromyographic biofeedback therapy and kinesitherapy can effectively improve the limb motor function of patients with radial nerve injury

Dual-energy X-ray absorptiometry(DEXA),scanning electron microscopy,and bone biomechanical test were used to assess comprehensively bone quantity and quality of ovariectomized rats. In OVX rats,not only bone mineral density (BMD) of lumbar vertebrae in vivo and vitro,but also BMD of femora (except for R3 region) and proximal metaphysis(R1 region) in vitro decreased obviously (P<0.01)，whose bone loss rates of L5 and L6 were the highest and achieved 13%; the trabeculae of OVX rats were few，fine, and discontinued and there were lacunae on the surface;in OVX rats,both compressive strength of vertebral bodies and the mechanical properties of femora decreased;the falling degree of the former was greater;the maximal compressive power of lumbar vertebrae decreased with 33.32%. We conclude that after 4-month post-ovariectomy, the bone quantity and quality of six-month-old rats decreased, especially in the area of abundant cancellous bone such as vertebral bodies,distal femora; the assessment of the efficiency of new drugs to prevent and treat postmenopausal osteoporosis using rat models should include these drugs' effects to the bone mass, the bone structure, and the bone strength.

Objective To study the effect of comprehensive treatment on common peroneal nerve injury. Methods 80 patients with common peroneal nerve injury were divided into treatment group (n=40) and control group (n=40). The treatment group accepted ultrashort wave, modulated medium frequency electrotherapy and electromyographic biofeedback therapy, while the control group accepted medication,acupuncture and excecise. All the patients were assessed with Fugl-Meyer assessment (FMA) in lower limbs before and after treatment.The effectiveness were recorded with MCRR. Results The scores of FMA of lower limb significantly improved after treatment and improved more in the treatment group than in the control group (P<0.05). The excellent and good rate was 80.00% in the treatment group, and 50.00% in the control group (P<0.01). Conclusion It is effective of comprehensive treatment on common peroneal nerve injury.

Ojective To compara the individual differences and clinical efficacy of cis-atracurium intermittent bolus injected according to fat-free mass and real body weight. Methods Forty patients (ASAI-II) who had no neuromuscular disease and underwent selective abdominal surgery under general anesthesia were randomly divided into group FFM (n=20) and group RBW(n=20) according to the different administration method. The responses of adductor pollicis to train-of-four (TOF) stimulation were monitored. Anesthesia was induced with propofol 2 mg/kg, fentanyl 3 ug/kg, cis-atracurium 129.6μg/kg (group FFM) or 100μg /kg (group RBW),and maintained with propofol and fentanyl given by target-controlled infusion. Intubation was attempted when T1 reached maximal inhibition. When the TOF stimulus T1 recovery to 5%, both group additional cis-atracurium 64.8 μg/kg (group FFM) or 50μg /kg (group RBW). The onset time, nonresponsive time, clinical duration, recovery index, pharmacological duration, cis-atracurium consumption, interval and frequency were recorded. Results No significant differences were found in general, interval, frequency,onset time, clinical duration, nonresponsive time,recovery index, pharmacological duration between the two groups (P > 0.05); There were significant differences in the cisatracurium consumption between two groups (P < 0.05); Compare with the group RBW, the differences of pharmacological duration and nonresponsive time between different individuals in group FFM were smaller (P < 0.05). Conclusion It can reduce the individual differences of muscle relaxant effect to apply cis-atracurium and cis-atracurium consumption according to fat-free mass.

Objective To investigate the effects of N - acetylcysteine (NAC) on apoptosis and the expressions of Fas/FasL mRNA in lung tissue of rats with paraquat - induced acute lung injury.Methods Forty five male SD rats were randomly (random number) divided into normal control group,paraquat (PQ) group,and NAC treatment group.The rat model of acute lung injury was made with 2％ PQ induction in dose of 25 mg/kg injected,and NAC was injected into the PQ poisoning rats (200 mg/kg) 30 minutes after PQ administration in NAC treatment group.In the control group,equal amount of saline instead was injected into the rats.Apoptosis was detected by using TUNEL method and the expressions of Fas/FasL mRNA were evaluated by using reverse transcription polymerase chain reaction (RT- PCR),and the levels of Fas/FasL protein were detected by using western blot analysis.Results Compared with control group,cell apoptosis and expressions Fas/FasL mRNA in PQ group were significantly different ( P ＜ 0.05 ).Compared with PQ group,cell apoptosis and expressions Fas/FasL mRNA in NAC group were significantly decreased,were significant lower (P ＜ 0.05).Conclusions NAC inhibited apoptosis in lung tissue of rats with paraquat induction by regulating the activation of Fas/FasL systems.

Objective To observe the expression of tumor necrosis factor-α(TNF-α)in acute lung injury caused by paraquat(PQ)in rats,and investigate the mechanism of the rhubarb in respect of pmteetive effects.Method PQ intragastrically poisoning at the dose of 50 mg/kg made a model of the acute lung injury in Sprague-Dawley(SD)rats.Totally 144 adult healthy SD rats(72 female,72male)were randomly divided into control group (group A,n=24),poisoned group(group B,n=48),rhubarb treated group(group C,n=48)and the shaln poisoning group(group D,n=24).Rats of group B and group C were poisoned intmgastrically with PQ(50 mg/kg).and rats of group C and group D were intervened intragastrieally with 300 mg/(kg·d)of rhubarb in 15 min-utes.The white blood cells and total cells in bronchoalveolar lavage fluid(BALF)were counted by using a blood cell counting plate and the protein content of BALF was measured by using the way of Lowry in order to calculate the neutmphiks pereentage and lung permeability index.A small portion of left lung was stained with HE to observe the pathological changes and the expression oftumor necrosis factor-α in the rest of the left lung was observed with immunohistochemistry.The data were handled by the analysis of variance and NK method using SPSS 14.0.Re-suits Compared with group A,the lungs of rats mainly showed congestion,edema and leukocytes infiltration in group B,and fibrosis was found onlyt in a few rats.And the rate neutrophils percentage,protein content and lung permeability index in BALF increased(P＜0.01).The expression of TNF-α were obviously inereased at 12 hours after PQ poisoning,and immtmohistochemistry score (IHS)was higher,and peaked at 24 hours later(P＜0.05),then remained on a high level for a while and sluggishly declined.Compared with group B,the changes of above mentioned were alleviated obviously,and the expression of TNF-α delayed with the less magnitude of increasing an an obvious tendency of less expression.Compared with group B,delayed,lower increasing extent,obviously re-ducing tendency in group C with statistical difference in IHS(P＜0.05).Conclusions Rhubarb ameliorates a-cute lung injury caused by PQ poisoning in rats by means of inhibiting the expression of TNF-α in turn to alleviate inflammatory reaction.
