Objective :To explore influence of nicorandil on plasma levels of high sensitive C reactive protein (hsCRP) and soluble T cell CD40 ligand (sCD40L) and therapeutic effect of nicorandil in patients with microvascular angina pectoris .Methods :A total of 102 patients with microvascular angina pectoris were enrolled ,randomly and equally divided into routine treatment group (received routine comprehensive treatment ) and nicorandil group (received nic-orandil based on routine comprehensive treatment ,5mg ,3 times/d) ,both groups were treated for eight weeks . Plasma levels of hsCRP and sCD40L were measured and compared between two groups before and eight weeks after treatment ,and therapeutic effect was compared between two groups .Results : Compared with before treatment there were significant reductions in plasma levels of hsCRP and sCD 40L in both groups after eight weeks ;compared with routine treatment group after treatment ,there were significant reductions in plasma levels of hsCRP [ (2.63 ± 0.25) mg/L vs.(1.80 ± 0.28) mg/L] and sCD40L [ (71.88 ± 3.71) pg/ml vs .(55.25 ± 2.47) pg/ml] in nicorandil group , P＝0. 001 all.Total effective rate of nicorandil group was significantly higher than that of routine treatment group (78.43% vs.56.86%,P＝0.02).Conclusion :Nicorandil can significantly rise clinical effect ,reduce plasma levels of hsCRP and sCD40L in patients with microvascular angina pectoris .

Comparison of Different Dosages of Rocuronium on Abdominal Wound Closure / 昆明医科大学学报

Objective To evaluate the effects of different dosages of rocuronium on abdominal wound closure under general anesthesia.Methods Ninety ASA class I or II patients scheduled for elective abdominal surgery under general anesthesia were randomized into three groups with 30 cases each.Each group received rocuronium 1 time of ED95 (0.3 mg/kg),0.5 time of ED95 (0.15 mg/kg),0.2 time of ED95 (0.06 mg/kg) respectively when closing the abdominal wall.TOF recovered to 25%, 75%, 90%, time of eye-opening on command, time of head-lift for more than 5 seconds,extubation time, the rate of upper airways obstruction after extubation and the satisfaction score for the muscle relaxation to general surgeons were recorded.Results TOF values had no significantly different among the three groups before abdominal wound closure (P＞0.05).Compared with group A and group B,time of TOF in group C was significangtly increased after administration of rocuronium (P＜0.05) . Time of TOF recovery to 25%, 75%, 90%in group C were significangtly decreased (P＜0.01).Compared with group A and group B, time of eye-opening on command ,head-lift for more than 5 seconds and extubation time were significantly shorter in group C.There were 8,4,0 patients undwent upper airways obstruction among each group respectively after extubation (P＜0.05).The satisfaction score for muscle relaxation among three groups had no significant difference.Conclusion An additional administration of 0.2 time of ED95 (0.06 mg/kg) rocuronium before abdominal wound closure in abdominal surgery can achieve satisfactory muscle relaxation for surgeons.

Impacts of high-volume hemofiltration on hemodynamics and vascular endothelial permeability in children with septic shock / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To investigate the effects of high-volume hemofiltration (HVHF) on hemodynamics, vasoactive factors, and vascular endothelial permeability in children with septic shock by a comparative analysis.</p><p><b>METHODS</b>Thirty-six children who were diagnosed with septic shock between January 2013 and September 2014 were randomly divided into control and observation groups (n=18 each). Children in the control group were treated with the standard-volume hemofiltration (SVHF), while children in the observation group were treated with HVHF. The hemodynamic indices and levels of vasoactive factors including 6-keto-prostaglandin F1α (6-keto-PGF1α), thromboxane B2 (TXB2), soluble E-selectin (sE-selectin), and endothelium-derived relaxing factor (EDRF) were determined before and after treatment. In addition, the effects of ultrafiltrate on endothelial cell permeability were assessed.</p><p><b>RESULTS</b>Compared with the control group, the observation group had significantly higher mean arterial pressure, significantly higher blood oxygen saturation, and a significantly lower heart rate after treatment (P<0.05). The levels of TXB2 and sE-selectin were significantly lower in the observation group than in the control group (P<0.05), while the levels of 6-keto-PGF1α and EDRF were significantly higher in the observation group than in the control group (P<0.05). Compared with the control group, the ultrafiltrate significantly attenuated the transepithelial electrical resistance in the observation group (P<0.05).</p><p><b>CONCLUSIONS</b>Compared with SVHF, HVHF is a more effective approach for improving the hemodynamics and levels of vasoactive factors and reducing the vascular endothelial permeability in children with septic shock.</p>

Clinical characteristics and prognosis of 33 children with severe acute respiratory syndrome in Guangzhou area / 中华儿科杂志

<p><b>OBJECTIVE</b>Since the outbreak of a highly contagious new pneumonia, atypical pneumonia or severe acute respiratory syndrome (SARS) occurred in Guangzhou area, 33 children with this syndrome were treated in the authors' hospital. The present study aimed to understand clinical characteristics and prognosis of pediatric SARS patients in Guangzhou area.</p><p><b>METHODS</b>Clinical manifestations, laboratory and radiologic findings, therapeutic approaches and prognosis of the 33 children with SARS in Guangzhou area were analyzed.</p><p><b>RESULTS</b>Of the 33 cases, 17 were males and 16 were females. The age was between 3 months to 13 years, and 3 - 12 years old patients accounted for 82%. Five (15%) cases had an evident history of contacting SARS patient before the symptoms occurred. Another 5 (15%) cases had a history that contacts of these patients (family members or friends) developed fever and/or cough later. The most common symptoms in this cohort were fever (100%) and cough (91%). Most of the cases had high fever, higher than 39 degrees C. Near half of the cases had nonproductive cough. The initial blood cells count showed that total white blood cell (WBC) count was (2.5 - 9.7) x 10(9)/L. In 22 (67%) cases the WBC count was < 5.0 x 10(9)/L, and in 10 (30%) WBC was (5.0 - 7.0) x 10(9)/L, in 18 cases most of the WBC were lymphocyte count. Chest radiograph showed patchy infiltrates, in 15 cases the changes were unilateral, and in 18 were bilateral. The radiologic changes developed fast, in some cases the changes progressed from one side to both sides. The opacity was absorbed slowly, significant absorption took in average two weeks. Elevated ALT was found in 3 cases and elevated CK-MB in 2 cases. Treatment included isolation, good ventilation of the ward, bed rest, supportive regimens, low volume oxygen inhalation, use of Chinese traditional medicine, antibiotics to prevent bacterial infection, and anti-inflammation therapy. All the patients recovered and discharged from hospital after a mean period of 10.0 +/- 3.8 days.</p><p><b>CONCLUSION</b>SARS in children may have its own characteristics. The main clinical manifestations were high fever and cough while no severe toxic symptoms, nor respiratory failure was seen; few symptoms or signs suggesting involvement of systems other than respiratory system were seen. Chest radiograph showed uni- or bilateral asymmetric air-space infiltrates which could worsen quickly and were absorbed slowly. Though there were severe changes in the lung, the patients might not have corresponding symptoms or signs. The total white blood cell count in peripheral blood did not increase. All the patients studied had a favorable outcome after the combined treatment.</p>

Significance of Monitoring Serum Level of Gentamycin in Children with Serious Illness / 实用儿科临床杂志

Objective To explore the serum level of gentamycin for orally in children with serious illness.Methods The serum level of gentamycin in 41 children who were in serious illness [multiple organ dysfunction(MODS)group with 21 cases and non-MODS group with 20 cases ] were monitored and the patients were treated with select decontamination of the digestive tract(SDD) from October 2004 to April 2005.Dosage:10 mg/(kg?d),orally taken three times(every 8 hours) one day.The blood after taking the drug one hour later in the fourth day was selected and the serum level of getamycin was monitored.Results Thirty-six children of 41 cases serum level of gentamycin were negative and 5 children(4 in MODS group and 1 in non-MODS group) who had alimentary tract hemorrhage were masccline in serum after taking gentamycin one hour later in the forth day.The absorption of gentamycin from enteric after orally was not(rela)-ted to MODS.There were statistics value between the gestrintestinal tract ulcer and serum level of gentamycin.Conclusions The safety for treating the children in serious illness with gentamycin for SDD is obvious.But we suggest to monitor the serum level of gentamycin for who has severe alimentary tract hemorrhage together with insufficiency of liver and kindey.
