Influence of Sodium Bicarbonate (SB) in several doses on some pharmacokinetic parameters and the anti-inflammatory action of Aspirin (ASP) in a large dose was studied in rats of experimental inflammatory model. It was showed that SB significantly reduced the Tp, T_(1/2), AUC and increased the Ke, Cmax of plasma salicylic acid (SA). The anti-inflammatory effect of ASP was diminished as well. All of the changes, were enhanced as the doses of SB increased. The results in this paper suggested that combining ASP with SB in antirheumatic therapy might be an unreasonable regime.

Objective To analyze the symptoms and signs in forty-five Lambert-Eaton myasthenia syndrome (LEMS) patients retrospectively. Characteristics of electrophysiological examinations were investgated. Methods Forty-five LEMS patients were reviewed and information gathered regarding clinical complains neurological symptoms, and other concomitant diseases. The records showed that repetitive nerve stimulation (RNS) and nerve conduction velocity (NCV) were performed in all patients. Needle electromyography (EMG) and skin sympathetic response (SSR) were performed in some patients. Results (1) The mean age of neurological clinical onset age was (51.2 ±6. 8) years old. The two most common symptoms were slight weakness of lower extremities ( n = 35 ) and upper extremities (n= 5). Dysarthria was found in 3 patients and neck weakness in 2 patients. Tendon reflex decreased and disappeared in 38 patients. Autonomic nervous system manifestations were presented in 30 patients. (2) RNS increasing was observed in all patients from 156% to 636%. Low frequency RNS abnormalities were found in 29 patients.Sensory nerve conduction velocity abnormalities or sensory nerve conduction velocity combined motor nerve conduction velocity abnormalities were found in 19 patients ( 42% ). Of the 30 patients who underwent a needle EMG examination, 20 had myogenic or neurological damage. Thirteen abnormal findings were observed in 25 patients who underwent SSR examination. Conclusion The most common manifestations were weakness in lower extremities and autonomic nervous system dysfunction. Many abnormal electrophysiological results were found in LEMS patients, including NCV and EMG abnormalities. These findings indicated that clinical manifestations exceed the neuromuscular junction and perhaps included the peripheral nerve and muscle.

Objective To study the role of hydrogen sulfide(H2S)in the pathogenesis of acute lung injury (ALI)-induced oleic acid(OA)and its regulatory effects on the inflammatory msponse.Method The ALI models in SD rats were produced by intravenous injection of OA(0.1 ml/kg).Forty-nine male SD rats were divided into three groups randomly:control group,OA group and OA+sodium hydrosulfide(NaHS)group.Rats of OA group and OA+NaHS group were sacrificed at 2,4 and 6 hours after the administration of OA,respectively.Rats of control group were sacrificed at 6 hours after intravenous normal saline(0.1 ml/kg).PaO2,lung tissue wet/dry(W/D)ratio and IQA score were determined.The concentrations of H2S in lung tissue and plasma were tested by sensitive sulphur electrode.The IL-6.IL-8 and IL-10 levels were measured by doubleantibody sandwich ELSIA.Results Compared with control group,of lung tissues was observed in rats treated with OA induced ALI,which led PaO2 dropped,and lung tissue W/D ratio,PMN%in alvedolar lavage and IQA raised score in the lung at 2,4 or 6 hours after OA injection(P＜0.01).In addition,IL-6,IL-8,and IL-10significantly increased,IL-6[plasma,control:(73.95±14.68)pg/ml,2 h:(186.70±23.85)pg/ml,4 h:(238.50±26.46)pg/ml,6 h:(215.95±25.86)pg/ml,P＜0.01;lung tissue,control:(60.58±12.91)pg/ml,2 h:(160.32±24.57)pg/ml,4 h:(195.27±46.28)pg/ml,6 h:(185.66±17.42)pg/ml,P all =0.000)],IL-8[plasma,control:(80.69±20.42)pg/ml,2 h:(184.11±19.51)pg/ml,4 h:(286.20±53.34)pg/ml,6 h:(241.30±45.85)pg/ml,P＜0.01;lung tissue,control:(69.14±15.96)pg/ml,2 h:(174.10±20.36)pg/ml,4 h:(249.02±31.17)pg/ml,6 h:(237.74±34.18)pg/ml,P＜0.01] and IL-10[plasma,control:(39.78±8.97)pg/ml,2 h:(111.18±11.46)pg/ml,4 h:(115.60±13.91)pg/ml,6h:(102.41±9.93)pg/ml,P＜0.01;lung tissue,control:(71.86±14.19)pg/ml,2 h:(126.96±18.72)pg/ml,4 h:(151.88±27.61)pg/ml,6 h:(137.28±14.22)pg/ml,P all=0.000] levels.in association with a decreased H2S content of plasma lung tissue decreased in[plasma,control:(36.58±6.80)μmol/L,2 h:(21.30±2.75)μmol/L,4 h:(20.63±1.26)μmol/L,6 h:(20.00±1.60)μmol/L,P＜0.01;lung tissue,control:(27.61±2.20)μmol/L,2 h:(20.67±1.37)μmol/L,4 h:(20.79±1.10)μmol/L,6 h:(18.92±0.75)μmol/L,P＜0.01]were observed in the plasma and lung tissue of OA-treated rats compared to controls.Administration of NaHS prior to OA treatment could lessen the lung pathologic changes induced by OA and elevate the concentrations of H2S in plasma[4 h:(26.67±3.44)μmol/L vs(20.63±1.26)μmol/L,P=0.042;6 h:(26.98±4.93)μmol/L vs(20.00±1.60)μmol/L,P＜0.05]and lung tissue[4 h:(23.20±1.48)μmol/L vs(20.79±1.10)μmol/L,P=0.011;6 h:(21,43±1.79)μmol/L vs(18.92±0.75)μmol/L,P=0.016].At the same time,the levels of IL-6 in plasma(185.37±21.98)pg/ml vs(238.50±26.46)pg/ml,4 h,P=0.000;(124.22±21.84)pg/ml vs(215.95±25.86)pg/ml,6 h,P＜0.01]and IL-8(199.40±34.56)pg/ml vs(286.20±53.34)pg/ml,4 h,P＜0.01;(146.58±20.23)pg/ml vs(241.30±45.85)pg/ml,6 h,P＜0.01]decreased significantly,but the level of IL-10(154.48±18.08)pg/ml vs(115.60±13.91)pg/ml,4 h,P=0.000;(138.06±20.01)pg/ml vs(102.41±9.93)pg/ml,6 h,P＜0.01]increased significantly.Conclusions The levels of endogenous H2S drop during the course of ALI oleic acid induced in rats.Exogenous H2S could decrease the levels of inflammatory factors(IL-6and IL-8),but increase the level of anti-inflammatory factors(IL-10).It could change the ratio of inflammatory factors/anti-inflammatory factors and therefore play a protective role against oleic acid induced ALI in rats.

Aim To investigate the inhibitory effect of hydrogen sulfide on expression of elastin in hypoxic pulmonary hypertensive (HPH) rats. Methods Twenty-four rats were randomly divided into three groups:control group (n=8), hypoxic group (n=8) and hypoxia+NaHS group (n=8). Pulmonary artery mean pressure (mPAP) of three group rats was measured via right ventricular catheterization. Right ventricle and left ventricle+septum of each rats were isolated from intact rats and weight of right ventricle/(weight of left ventricle+septum) ratio was calculated. The percentage of muscularized arteries of small pulmonary arteries was measured using a light microscope. The expression of elastin and TGF-? in pulmonary artery smooth muscle cells was observed with immunohistochemistry. Results mPAP and weight of right ventricle/(weight of left ventricle+septum) ratio were significantly higher in rats of hypoxic group than those of control group (P

Objective To investigate the time and rate of generalization developed from ocular symptoms in adults to generalized myasthenia gravis (GMG).Methods The data from 456 adult patients who started on ocular symptoms during Jan 2005 to Jan 2012 were retrospectively studied,with a follow-up period of 3 months to 17 years.The data included transfer time,Osserman type,difference between steroids group and no-steroids group.Results (1) During the follow-up period,197 (43.2％) patients developed to generalized myasthenia gravis,58.4％ (115/197)in one year after onset of ocular symptoms,74.1％ (146/197) in 2 years and 80.7％ (159/197) in 3 years.86.8％ (171/197) developed to Osserman Ⅱ a or Ⅱ b.(2) Of 233 patients untreated with steroids,134 (57.5％) developed to GMG,while 63 (28.3％) of 223 patients who were treated with steroids developed to GMG (x2 =38.57,P ＜ 0.01).There were no difference between two groups in transfer time and Osserman type.Conclusion MG initiated from ocular syndromes in adults easily develops to GMG in 2 years.Patients treated with steroids have low chance of generalization.
