Journal of Applied Clinical Pediatrics 2004;0(12):-
Objective To explore the value of electroneurophysiological detection in diagnosis of children progressive muscular dystrophy (PMD).Methods The clinical features and laboratory data were analyzed in 32 children with PMD ,and electromyography(EMG) and nerve conduction velocity(NCV) were performed.Parameters studied included spontaneous activity , duration and amplitude of motor unit potential(MUP),pattern of recruitment as strong contracting,sensory conduction velocity(SCV),motor conduction velocity(MCV), distal latency and distal amplitude. Results The abnormality rates of spontaneous potentials was 49.2% and 80.9% in tibialis anterior.The decrease of duration of MUP was 29.7%-62.4%.Amplitude of strong contracting was significantly decreased.There were different from those in normal children(P

Objective To study the individualized dose of warfarin in treating atrial fibrillation in elderly patients. Methods Forty-one elderly in-patients with atrial fibrillation were recruited.Warfarin was used tO start anti-coagulation therapy with the target INR value 1.6-2.5.The data of demographic variables,concomitant diseases,medications and laboratory values were collected,then correlated these factors with the maintenance dose of warfarin. Results Warfarin dose requirements were significantly associated with age(r=-0.535,P<0.01),sex(r=-0.494,P<0.01),height (r=0.484,P<0.01),weight(r=0.453,P<0.01),body surface area(r=0.388,P<0.05),concomitant use of a sulfonylurea medication(r=-0.446,P<0.01)and serum albumin level(r=0.520,P<0.01).The multivariate regression model includedthe variables of age,sex,serum albumin level and concomitant use of a sulfonylurea medication.This algorithm explained 65.4%of the variance in the maintenance dose of warfarin(R=0.808,R2=65.4%). Conclusions The warfarin dose in treating atrial fibrillation in elderly patients can be estimated from demographic,clinical and laboratory factors that can be obtained at the time of warfarin initiation.

Objective To investigate the incidence and risk factors of acute kidney injury (AKI) in patients with multiple soft tissue contusion.Methods A total of 513 patients diagnosed as multiple soft tissue contusion in the First Affiliated Hospital of Xinjiang Medical University from January 1,2008 to January 1,2013 were retrospectively analyzed.Demographics,clinical data and laboratory examinations before and after AKI were collected and analyzed.Results The age of all subjects was 31.30 (12-78) years old with the male to female ratio of 2.1∶ 1.AKI occurred in 74 cases with an incidence rate of 14.4%.No AKI was observed in patients with assault injuries,while AKI was found in 27 cases (36.5%) with car accident injuries and 4 cases (5.4%) with other injuries.AKI showed in 1 case(1.4%) with damaged area under 1%,in 4 cases(5.4%) with damaged area ranged from 1% to < 3%,10 cases (13.5%) with damaged area ranged from 3% to 5% and 19 cases (25.7%) with damaged area over 5% with significant difference among the groups (P < 0.01).Incidence rate of AKI was significantly higher in patients with chronic kidney disease (CKD) than those without CKD (54.5% vs 20.3%,P < 0.01).Two of the AKI cases died,with a mortality rate of 2.7%.Multivariate logistic regression analysis showed that the followings were the independent risk factors for the occurrence of AKI in patients with multiple soft tissue injuries:age (OR =1.996),basic serum creatinine (OR =0.976),basic evaluated GFR (eGFR) (OR =0.964),serum potassium (OR =2.117),myoglobin (OR =0.950) and damaged area (OR =1.811).Conclusions Incidence rate of AKI is quite high in multiple soft tissue contusion.Age,basic serum creatinine,basic eGFR,serum potassium,myoglobin and damaged area are the independent risk factors for the occurrence of AKI in patients with multiple soft tissue injury.

Objective To review the experience of perioperative management and effect of valve replacement combined with renal dysfunction.Methods 536 cases of valve replacement.According to preoperative glomerular filtration rate(GFR),renal dysfunction was classified as normal in 322 cases,mild in 162,moderate in 40 and severe in 12.Logistic regression analysis was used to assess the effect of preoperative renal dysfunction on operative mortality and morbidity.Results Patients with a lower GFR were older and more likely to have hypertention.They also tended to have larger left ventricular end-diastolic diameter and worse left ventricular ejection factor.Operative mortality rose inversely with declining renal function,from 2% for those with normal renal function to 17% for patients with severe renal dysfunction.Renal dysfunction was significantly associated with a large blood transfusions,re-intubation,longer mechanical ventilation,intensive care unit stay and hospital stay.Conclusion Preoperative renal dysfunction is an important factor of postoperative mortality and morbidity for valve replacement.We must pay more attention to perioperative management.

Objective To estimate the biological effects of leptin on human HaCaT keratinocytes and explore their molecular mechanisms.Methods Cell counting kit-8 (CCK-8) was used to evaluate the proliferation of cultured HaCaT cells treated with different concentrations of leptin for 24 and 48 hours.Some HaCaT cells were classified into four groups to remain untreated,be treated with leptin (100 μg/L) and piceatannol (a specific inhibitor of STAT3 phosphorylation) alone or in combination for 24 hours,respectively,followed by the evaluation of cell proliferation using CCK-8 kit.Flow cytometry was performed to assess cell cycle of HaCaT cells treated with leptin of 100 μg/L,Western blot to determine the phosphorylation level of Erk1/2 and STAT3 in HaCaT cells treated with leptin of 100 μg/L for different durations.Statistical analysis was done by Student's t-test for unpaired data using GraphPad Prism 5 software.Results The proliferation of HaCaT cells was accelerated to different degrees after treatment with leptin of 50 and 100 μg/L for 24 and 48 hours,and the accelerating effect was in a dose-dependent manner within 24 hours (r =0.9989,P < 0.05).Piceatannol apparently inhibited the promotive effect of leptin on the proliferation of HaCaT cells.There was an obvious elevation in the percentage of cells at S phase ((57.70 ± 5.88)% vs.(42.50 ± 7.55)%,P > 0.05),but a significant decrease in that at G0/G1 phase ((39.70 ± 1.57)% vs.(45.20 ± 1.44)%,P < 0.05),with a significant increase in proliferation index (0.603 ±0.0157 vs.0.564 ± 0.0144,P < 0.05) in HaCaT cells treated with leptin of 100 μg/L for 24 hours compared with the untreated controls.Western blot showed that leptin of 100 μg/L markedly enhanced the phosphorylation level of STAT3 in HaCaT cells.Conclusion Leptin may upregulate the proliferation of HaCaT cells through activation of STAT3 pathway.
