Effect of Nitric Oxide on Potassium Channels of Rat Airway Smooth Muscle Cells

Summary: The effect of nitric oxide donor sodium nitroprusside (SNP) on resting membrane potential (Em) and potassium currents of the bronchial smooth muscle cells from rats was investigated. All experiments were conducted in conventional whole-cell configuration. The changes of Em and potassium currents after addition of 0. 1 mmol/L SNP were measured under the current-clamp mode and the voltage-clamp mode respectively. Results showed that (1) SNP could decrease the Em from --33. 8±7.4 mV to -43. 7±6. 7mV (n=10, P＜0. 01); (2) SNP could increase the Ca2+-activated K+ channel peak currents under ramp protocol from 466.9±180. 1 pA to 597. 7±237. 6 pA (n= 7, P＜0. 01), and the currents under pulse protocol at +50 mV were increased from 544.2±145.4 pA to 678.1±206. 2 pA (n=6, P＜0.05); (3) SNP also could increase voltage-gated K+ channel peak currents under ramp protocol from 389. 6±84. 1 pA to 526. 7±98. 7 pA (n=7, P＜0. 01), the currents under pulse protocol at +50 mV were increased from 275.7±85.2 pA to 444.3±128.5 pA(n=6,P＜0. 01). It was concluded that SNP increases the activities of Ca2+-activated K+ channels and voltage-gated K+ channels and leads to K+ efflux and hyperpolarization of the cell membrane, resulting in a decrease of the cell excitement.     

Expression of Platelet Membrane Glycoprotein Ib/Ⅸ/Ⅴ Complex,a Receptor of Thrombin,in Patients with Hemorrhagic Thrombopathy

To investigate the role of platelet membrane glycoprotein （GP） Ib/Ⅸ/Ⅴ complex and its subunit GP Ibα in patients with hemorrhagic thrombopathy （HT）, the expressions of GP Ib/Ⅸ/Ⅴ complex and GP Ibα,defined as mean fluorescence intensity （MFI）, were assessed by flow cytometry. The maximum aggregation of platelet was determined by turbidity method. These indicators were compared among 68 HT patients with the presenting complaint of hemorrhage, 33 well-controlled HT patients and 32 normal healthy subjects. The results showed that the MFI of GP Ib/Ⅸ /Ⅴ complex and GP Ibα was markedly lower in HT patients with current hemorrhage than that in the healthy subjects, with difference being statistically significant （P〈0.05）. There was no significant difference in the expressions of GP Ib/ Ⅸ/ Ⅴ complex and GP Ibα between well-controlled HT patients and normal healthy subjects （P〉0.05）. It was concluded that the expression of GP Ib/Ⅸ /Ⅴ complex, the receptor of thrombin and von Willebrand factor, was down-regulated in HT patients with current hemorrhage, which might result in the dysfunction of platelet aggregation and recurrence of HT.

Effect of Trace Elements on Retinopathy of Prematurity

The effect of the trace elements on retinopathy of prematurity(ROP) were studied.Thirty preterm infants who had potential high risk factors of ROP were selected as observation group and 18 normal infants as control groups.By using atom spectrophotometer,the contents of serum trace elements(Mg,Cu,Zn,Mn,Se) were measured and analyzed statistically.The contents of serum Zn,Cu and Se in observation group were 0.75±0.22,0.41±0.20 and(134.07±71.57)×10-3 mg/L respectively,and 0.55±0.12,0.65±0.194 and(202.92±44.71)×10-3 mg/L in control group respectively(P<0.01).The contents of Cu and Se were obviously lower and that of Zn higher in observation group than those in control group.The same results were obtained between the infants with ROP and controls(P<0.01).However,there was no significant difference in the contents of serum Mg and Mn between two groups(P>0.05).It was concluded that the contents of serum Cu and Se in preterm infants who had high risk factors of ROP were obviously lower than in the controls.The contents of serum Cu and Se in the ROP infants were also much lower while contents of Zn much higher.Attention should be paid to the detection of the trace elements in preterm infants in order to prevent the deficiencies of Cu and Se.Only in this way can we prevent the deficiencies of Cu and Se,so as to decrease the ROP risk factors and prevent the disease.     

K<Superscript>+</Superscript> channels and their effects on membrane potential in rat bronchial smooth muscle cells

Summary In order to investigate the K⁺ channels and their effects on resting membrane potential (Em) and excitability in rat bronchial smooth muscle cells (BSMCs), the components of outward K⁺ channel currents and the effects of K⁺ channels on Em and tension in rat bronchial smooth muscle were observed by using standard whole-cell recording of patch clamp and isometric tension recording techniques. The results showed that under resting conditions, total outward K⁺ channel currents in freshly isolated BSMCs were unaffected by ATP-sensitive K⁺ channel blocker. There were two types of K⁺ currents: voltage-dependent delayed rectifier K⁺ channel (K_v) and large conductance calcium-activated K⁺ channel (BK_Ca) currents. 1 mmol/L 4-aminopyridine (4-AP, an, inhibitor of K_V) caused a significant depolarization (from −8.7±5.9 mV to −25.4±3.1 mV,n=18,P<0.001). In contrast, 1 mmol/L tetraethylammonium (TEA, an inhibitor of BK_Ca) had no significant effect on Em (from −37.6±4.8 mV to −36.8±4.1 mV,n=12,P>0.05). 4-AP caused a concentration-dependent contraction in resting bronchial strips. TEA had no effect on resting tension, but application of 5 mmol/L TEA resulted in a left shift with bigger pD₂ (the negative logarithm of the drug concentration causing 50% of maximal effect) (from 6.27±0.38 to 6.89±0.54,n=10,P<0.05) in the concentration-effect curve of endothine-1, and a right shift with smaller pD₂ (from 8.10±0.23 to 7.69±0.08,n=10,P<0.05) in the concentration-effect curve of isoprenaline. It was suggested that in rat BSMCs there may be two types of K⁺ channels, K_v and BK_Ca, which serve distinct roles. K_v participates in the control of resting Em and tension. BK_Ca is involved in the regulation of relaxation or contraction associated with excitation. LIU Xiansheng, male, born in 1969, M. D., Ph. D.

Effects of Phorbol-12,13-dibuterate on Sodium Currents and Potassium Currents in Rat Trigeminal Ganglion Neurons

The effects of phorbol-12,13-dibuterate (PDBu) on total sodium current (INa-total), tet-rodotoxin-resistant sodium current (INa-TTXr), 4-AP-sensitive potassium current (IA) and TEA-sensitive potassium current (IK) in trigeminal ganglion (TG) neurons were investigated. Whole-cell patch clamp techniques were used to record ion currents in cultured TG neurons of rats. Results revealed that 0.5 μmol/L PDBu reduced the amplitude of INa-total by (38.3±4.5)% (n=6, P<0.05), but neither the G-V curve (control: V0.5 =-17.1±4.3 mV, k=7.4±1.3; PDBu: V0.5=-15.9±5.9 mV, k=5.9±1.4; n=6, P>0.05) nor the inactivation rate constant (control: 3.6±0.9 ms; PDBu: 3.6±0.8 ms; n=6, P>0.05) was altered. 0.5 μmol/L PDBu could significantly increase the amplitude of INa-TTXr by (37.2± 3.2)% (n=9, P<0.05) without affecting the G-V curve (control: V0.5=-14.7±6.0 mV, k=6.9± 1.4; PDBu: V0.5=-11.1±5.3 mV, k=8.1±1.5; n=5, P>0.05) or the inactivation rate constant (control: 4.6±0.6 ms; PDBu: 4.2±0.5 ms; n=5, P>0.05). 0.5 μmol/L PDBu inhibited IK by (15.6±5.0) % (n=16, P<0.05), and V0.5 was significantly altered from - 4.7±1.4 mV to -7.9 ±1.8 mV (n=16, P<0.05). IA was not significantly affected by PDBu, 0.5 μmol/L PDBu decreased IA by only (0.3±3.2)% (n=5, P>0.05). It was concluded that PDBu inhibited INa-total but enhanced INa-TTXr, and inhibited IK without affecting IA. These data suggested that the activation of PKC pathway could exert the actions.     

Altered Nutrition State in the Severe Multiple Trauma Patients Undergoing Adjuvant Recombinant Human Growth Hormone Nutritional Support Therapy

In order to observe the nutrition state in the severe multiple trauma patients undergoing adjuvant recombinant human growth hormone (rhGH) nutritional support therapy, 45 patients with severe multiple traumas (ISS>25) were randomly divided into 3 groups. All the 3 groups had been supplied with nitrogen and caloricity according to the need of patients for 16 days. The rhGH therapy started 48 h after surgery and lasted for 14 days in two rhGH-treated groups in which rhGH was 0.2 and 0.4 U/(kg·d) respectively, and the resting group served as control one. The levels of nitrogen balance, prealbumin and safety variables (blood sugar, Na , TT3 and TT4) were observed and com- pared among the three groups. The levels of nitrogen balance on the postoperative day (POD) 3 and 5 in the rhGH-treated groups were -1.28±3.19, 5.45±2.00 and -0.18±2.55, 6.11±1.60, respectively, which were significantly higher than those in the control group (-5.17±1.68 and -1.08±3.31, P<0.01). The values of prealbumin on the POD 3 and 5 in the rhGH-treated groups were 180.19±27.15, 194.44±50.82 and 194.94±29.65, 194.11±16.17, respectively, which were significantly higher than those in the control group (117.42±19.10 and 135.63±28.31, P<0.01). There was no sig- nificant difference between the rhGH 0.2 U/(kg·d) group and rhGH 0.4 U/(kg·d) group in both of the levels of nitrogen balance and prealbumin. It is concluded that the nutritional support therapy with adjuvant rhGH which starts 48 h after surgery improves the nutrition state of the patients with severe multiple trauma. It is safe for severe multiple trauma patients who accept rhGH at the dose of 0.2 and 0.4 U/(kg·d).

Summary Whether tranilast had antagonistic effect on proliferation inhibition and collagen synthesis promotion induced by TGF-\sB₂ in cultured human trabecular meshwork cells was investigated. Suspension of 1×10⁴ cultured human trabecular meshwork cells of 3–5 passage was distributed in each well of a 96-well disk and divided into control group and experimental group. After 24 h, 0 μg/ml (control), 12.5 μg/ml, 25 μg/ml, 50μg/ml tranilast with 3.2 ng/ml TGF-\sB₂ were added into the incubation medium. Another 24 h later, proliferation and collagen synthesis in cultured human trabecular meshwork cells were examined respectively by using tetrazolium-based semiautomated colormetric (MTT) assay and³H-proline incorporation with liquid scintillation technique. The results showed absorbance (A) values of the experimental groups were 0.9036±0.3017, 1.1361±0.1352, 1.2457±0.1524 according to the different concentrations of tranilast, and 0.8956±0.1903 of the control group. In comparison with the control group, 25 μg/ml (q=3.23,P<0.05), 50 μg/ml (q′=4.70,P<0.01) tranilast significantly antagonized the decrease of theA values induced by TGF-\sB₂ in the cultured human trabecular meshowrk cells. In comparison with the control group [817.37±124.21 cpm/10⁴ cells], 12.5 μg/ml (620.33±80.46 cpm/10⁴ cells,q′=4.26,P<0.05), 25 μg/ml (59.4.58±88.13 cpm/10⁴ cells,q′=4.81,P<0.01), 50 μg/ml (418.64±67.90 cpm/10⁴ cells,q′=8.62,P<0.01) tranilast significantly inhibited the incorporation of³H-proline into the cultured human trabecular meshwork cells promoted by TGF-\sB₂ in a dose-dependent manner. It was concluded that tranilast had the antagonistic effect on the proliferation inhibition and collagen synthesis promotion induced by TGF-\sB₂ in the cultured human trabecular meshwork cells.

Influence of L-arginine on the Expression of eNOS and COX2 in Experimental Pulmonary Thromboembolism

The influence of L-arginine on endothelial nitric oxide synthase (eNOS) and cyclooxy-genase 2 (COX2) was observed in experimental pulmonary thromboembolism and the action mechanism on pulmonary thromboembolism was explored. Wistar rats were randomly divided into control group, model group and treatment group. Pulmonary thromboembolism models were established by auto-blood back transfusion, and L-Arg 100 mg/kg was intraperitoneally injected after successful model preparation. The animals were sacrificed at 3 h, 1 day, 3 days and 7 days after embolism. Plasma NO, TXB2 and 6-Keto-PGF1αwere detected. The expression of eNOS and COX2 protein and mRNA in pulmonary tissues was detected by immunohistochemistry and RT-PCR respectively. The results showed that pulmonary thrombosis could be seen post pulmonary embolism and inflammatory reaction was significant. Plasma NO was decreased (P<0.01), and the levels of TXB2, 6-Keto-PGF1αand T/P ratio were all elevated. The expression of eNOS protein and mRNA in the pulmonary tissue was down-regulated (P<0.05), while that of COX2 protein and mRNA was upregu-lated (P<0.01). In treatment group, the level of NO was increased, the levels of TXB2 and T/P ratio were decreased, but the level of 6-Keto-PGF1αwas increased. The expression of eNOS protein and mRNA in pulmonary tissue was upregulated (P<0.05), while that of COX2 protein and mRNA was down-regulated (P<0.05). In conclusion, L-arginine can educe the role of pulmonary tissue protection through up-regulating the expression of intra-pulmonary NOS and down -regulating COX2 in pulmonary thromboembolism.     

Effect of Interleukin-1β on IA and IK Currents in Cultured Murine Trigeminal Ganglion Neurons

To investigate the effect of interleukin-1β (IL-1β) on IA and IK currents in cultured murine trigeminal ganglion (TG) neurons, whole-cell patch clamp technique was used to record the IA and IK currents before and after 20 ng/mL IL-1β perfusion. Our results showed that 20 ng/mL IL-1β inhibited IA currents (18.3±10.7)% (n=6, P<0.05). IL-1β at 20 ng/mL had no effect on G-V curve of IA but moved the H-infinity curve V0.5 from -36.6±6.1 mV to -42.4±5.2 mV (n=5, P<0.01). However, 20 ng/mL IL-1β had effect on neither the amplitude nor the G-V curve of IK. IL-1β was found to selec- tively inhibit IA current in TG neurons and the effect may contribute to hyperalgesia under various in- flammatory conditions.     

Simvastatin increases the activity of endothelial nitric oxide synthase via enhancing phosphorylation

3-hydroxy-3-methylgulutaryl-coenzyme A （HMG-CoA） reductase inhibitors or statins are a kind of lipid-lowering agents and have been used for the prevention and treatment of Cardiovascular diseases. Recent studies suggested that statins, besides lowering cholesterol, may protect vessels by enhancing the activity of endothelial nitric oxide synthase （eNOS）. In the present study, we investigated if simvastatin increases eNOS activity through its phosphorylation in 293 cells （293-eNOS） with stable expression of eNOS. The results showed that incubation of 293-eNOS cells with simvastatin （10 μm/L） for 2 h significantly increased in the activity of eNOS as shown by the conversion of L-arginine to L-citrulline （2889.70±201.51 versus 5630.18＋218.75 pmol/min . mg proteins） （P〈0.01）. Western blotting revealed that simvastatin increased phosphorylation of eNOS at 1177 （ser） and also 495 （thr） but did not affect the overall expression of eNOS or inducible NOS. Further study found that simvastatin raised phosphorylation levels of Akt and AMPK, and such effect could be antagonized by Akt inhibitor or AMPK inhibitor. These results suggest that simvastatin could stimulate,the activity of eNOS via its phosphorylation by Akt and AMPK, which provides a new mechanism, other than lipid-lowering effect, for the cardiovascular protection of statins.     

Protective effects of eplerenone on podocyte injury in adriamycin nephropathy rats

To investigate the protective effects of eplerenone on adriamycin-induced renal injury and the possible mechanisms involved,36 male Sprague-Dawley rats were randomly divided into control group,adriamycin nephropathy(AN) group and eplerenone-treated group(100 mg.kg-1.d-1 eplerenone).Blood pressure,24-h urinary protein,serum potassium,sodium and creatinine were measured 28 days after adriamycin injection(a single tail intravenous injection of 6.5 mg/kg adriamycin).The morphological changes of renal tissues were observed by light and electron microscopy.Immunohistochemistry and Western blotting were performed to examine the expression of TGF-β1 and desmin in renal cortex.The results showed that 28 days after adriamycin injection,there were no significant changes in the level of serum potassium,sodium,creatinine concentrations and blood pressure values in the rats of the three groups.Meanwhile,the 24-h proteinuria excretion in the AN group was significantly higher than that in the control group(P<0.01),but that in the eplerenone-treated group was substantially reduced when compared with that in the AN group(P<0.05).Mild mesangial cell proliferation and matrix expansion,diffuse deformation and confluence of foot processes in podocytes were found in the AN group.By contrast,rats in the eplerenone-treated group exhibited obvious attenuation of these morphological lesions.The protein expression of TGF-β1 and desmin in the AN group was markedly up-regulated in contrast to that in the control group(P<0.01),whereas that in the eplerenone-treated group was much lower than in the AN group(P<0.05).It was concluded that eplerenone may ameliorate the proteinuria and the development of pathological alteration in adriamycin-induced nephropathy presumably via the inhibition of cytokine release,and restore the morphology of podocytes independent of its blood pressure-lowing effects.     

Determination of CD30 expression on peripheral blood T lymphocyte subsets in patients with hemorrhagic fever with renal syndrome by FCM

Summary To determine the CD₃₀ expression on peripheral blood T lymphocyte subsets in patients with hemorrhagic fever with renal syndrome (HFRS) and its clinical implications, double immunofluorescence technique and flow cytometry were used. There was no significant difference among the severe group, mild-moderate group and normal control group in the CD+CD₃₀ T lymphocyte subset. While the CD₄ ⁺CD₃₀ ⁻ T cells of HFRS patients were increased and the difference between severe group and mild-moderate group or normal control group were very significant (P<0.01) and the difference between the mild-moderate group and normal control group was also significant (P<0.05). The CD₈ ⁺CD₃₀ ⁻ T cells were increased while the CD₈ ⁺CD₃₀ ^- T cells decreased obviously in HFRS patients, and the differences among three groups in both subsets were very significant (P<0.01). The results showed that the humoral immunity and cellular immunity are overactive in HFRS patients during acute phase. The loss of balance between T lymphocyte subsets may play an important role in the pathophysiology of HFRS and is closely correlated with the severity of the HFRS.

Clinical study on the treatment of premature ejaculation by Uighur medicine Gu-jing-mai-si-ha Tablet (固精麦斯哈片)

Objective:To observe the effect of Uighur medicine Gu-jing-mai-si-ha Tablet (固精麦斯哈片,GJMSHT) for treatment of premature ejaculation (PE) and to explore part of its mechanism. Methods:The condition of patients was scored by related questionnaire,and the intravaginal ejaculation latency time (IELT) was observed before and after GJMSHT treatment,with the blood levels of nitric oxide (NO) and prostaglandin F_(2α)(PGF_(2α)) detected in PE patients as well.The results were compared with those in the control group.Results:After treatment,the scores of PE and IELT,as well as the levels of NO and PGF_(2α) all increased significantly compared to those before treatment in the treated group (P<0.01),while in the control group,all the parameters were insignificantly changed (P>0.05). Therefore,the difference of these parameters between the two groups after treatment all showed statistical significance (P<0.01).Conclusion:GJMSHT could treat PE effectively,its mechanism is possibly by strengthening the coordination of the related smooth muscles through increasing the blood levels of NO and PGF(2α),and the endurance of patients to the cavitary effect of prostatico-urethral pressure,thus postponing the arrival of urgent ejaculatory feeling.
