Objective To investigate the effect of exercise on calcium modulin in myocardial sarcoplasmic re-ticulum of animal type 1 diabetes model in rat. Methods A total of 40 Spragne-Dawley rats were randomly dividedinto 4 groups : a normal control group, an exercise training group, a diabetes group and a diabetes plus exercise-traininggroup. At the end of 4- week-exercise training after the establishment of the diabetes model by intraperitoncal injectionof sterptozotocin, the animals were sacrificed and the level of blood glucose, insulin, blood fat and glycosylated serumprotein were tested. The gene expression of calcium modulin proteins was measured by reverse transcription-polymerasechain reaction, and the Western blotting technique was used to measure the protein of sarcoplasmic endoplasmic reticu-lure Ca<'2+> -ATPase (SERCA2) and phaspholamban (PLB). Results The level of biochemical indicator of exercisegroup is not affected when comparing with that of the control group, but significantly changed in diabetic group ( P <0. 01 ) ; The level of blood glucose, insulin, blood fat and glycosylated serum protein were ameliorated in diabetic rats inthe exercise training group. No significant changes in mRNA level of SERCA2, PLB and ryanodine receptor type 2(RYR2) were observed between control and diabetic group, the same to protein expression of SERCA2 and PLB. Butexpression of calcium modulin mRNA was significantly increased in exercise group and diabetic rats in the exercisetraining group comparing with that of the control and diabetic groups ( P < 0.01 ), the same to protein expression ofSERCA2 and PLB. Conclusion Exercise exerted good protective effects on the myocardial injury with 1 type diabetesrat, which might attribute to the upregnlated expression of SERCA2, PLB and RYR2 in diabetic rat heart.

Objective To compare the time-course of relaxant effect of rocuronium between patients with ocular and generalized myasthenia gravis (MG).Methods Twenty-seven ASA physical status I or Ⅱ patients with MG of both sexes,aged 12-64 yr,with body mass index of 17-26 kg/m2,scheduled for elective extended thymectomy,were divided into 2 groups according to Osserman stage:ocular group (group O,n =10) and generalized group (group G,n =17).Anesthesia was induced with iv injection of fentanyl 2 μg/kg,midazolam 0.05 mg/kg,and propofol 1.5 mg/kg.All patients were tracheal intubated and mechanically ventilated.Anesthesia was maintained with iv infusion of propofol 4-8 mg· kg-1 · h-1 and remifentanil 0.2 μg· kg-1 · min-1.Twitch tension was monitored in the adductor pollicis muscle by train-of-four stimulation of the ulnar nerve (intensity 60 mA,interval 12 s,frequency 2 Hz,wave length 0.2 ms).Rocuronium 0.6 mg/kg was injected intravenously after calibration.Mean arterial pressure (MAP),HR,heart rate variability (HRV) and low frequency and high frequency (LF/HF) ratio was recorded.The onset time of muscle relaxation,time for T1 to recover to 25％,time for T1 to recover to 50％ and recovery index were recorded.Results Compared with the baseline value,there were no significant changes in MAP,HR,HRV,LF/HF ratio at all time points in the two groups (P ＞ 0.05).Compared with group O,there was no significant change in the onset time of muscle relaxation,and the time for T1 to recover to 25％,time for T1 to recover to 50％ and recovery index were significantly prolonged in group G (P ＜ 0.05).Conclusion The duration of rocuronium-induced neuromuscular block is significantly longer in patients with generalized MG than those with ocular MG,while the onset time is comparable between the two groups.

OBJECTIVE: To investigate the effect of dxamethasone (DEX) on the expression of Tregs in allergic rhinitis (AR) mice, and explore the mechanism of glucocorticoid in the treatment of AR. METHOD: AR murine model was established by sensitization and challenge with OVA, besides intervention treatment with DEX was carried out in AR model. The behavior observation was used to evaluate the improvement effect of DEX on AR symptoms. The morphological characteristics of nasal tissues were observed by HE staining after fixation and decalcification. The mononuclear cells were obtained by grinding spleens, and the total RNA was extracted for reverse transcriptase polymerase chain reaction to investigate the level of mRNA expression of Foxp3. The changes of CD4+ Foxp3+ Tcells in spleen of mice were analyzed by flow cytometry. RESULT: BALB/c mice received OVA sensitization followed by OVA intranasal challenge, the frequencies of sneezing and nose-scratching increased significantly in AR group (44. 50 ± 5. 61 and 72. 94 ± 8. 76) compared with control group (12. 68 ± 1. 87 and 26. 76 ± .2. 89), P<0. 01; The frequencies decreased significantly in DEX group (26. 04 ± 3. 93 and 56. 79 ± 5. 64), P< 0. 05 compared with AR group. The continuity of nasal mucosa ciliated columnar epithelium in AR group was destroyed and appeared to be repaired in DEX group. Inflammatory cells infiltration was also markedly decreased by DEX treatment. The proportion of CD4+ Foxp3+ T cells in AR group (3. 89 ± 0. 39)% decreased, P<0. 01 vs control group (4. 63 ± 0. 15) %. DEX treatment induced production of Tregs (6. 89 ± 0. 49)%, P<0. 05 vs control group. DEX significantly increased the expression of Foxp3 mRNA (P<0. 05) compared with AR and control group. CONCLUSION DEX reduce upper airway allergic inflammation effectively, which may be mediated by promoting the expression of Foxp3 and inducing the amplification of Tregs in vivo.
