ABSTRACT
Objective Our retrospective study was aimed to analyze the clinical value of serum CEA and CA19-9 in patients with chole-lithiasis.Methods The clinical data of 98 patients with cholelithiasis and 44 patients with inguinal hernia received treatment in our hospital from February 2011 to February 2015 were retrospectively analyzed.The expressive levels of CEA and CA19-9 of the patients were detected and compared.The important roles of CEA and CA19-9 in the patients with cholelithiasis were analyzed.Results The levels of CEA,CA19-9 and inflammatory factors in normal group and control group had no statistical differences (P>0.05).The levels of CEA,CA19-9 and inflam-matory factors in rising group were higher than those in control group (P0.05),but the levels of CEA,CA19-9,inflammatory factors in rising group were obvi-ously decreased( P<0.05) .Conclusion The levels of CEA and CA19-9 in patients with cholelithiasis had correlation with inflammation of biliary tract,which will increased by severe choleithiasis.
ABSTRACT
The regulation mechanism of arecoline on rat hepatic CYP2E1 was studied in vivo. After oral administration of arecoline hydrobromide (AH; 4, 20 and 100 mg x kg(-1) x d(-1)) to rats for one week, the hepatic CYP2E1 mRNA level remained unchanged, but the hepatic CYP2E1 protein content was dose-dependently increased. Additionally, although the hepatic CYP2E1 activity was induced by AH treatment, the induction was attenuated with the increase in dosage. The results indicate that the effect of arecoline on rat hepaticdoes not involve transcriptional activation of the gene, but largely involves the stabilization of CYP2E1 protein against degradation or increased efficiency of CYP2E1 mRNA translation, and additionally involve the post- ranslational modification of CYP2E1 protein. Furthermore, the CYP2E1 response is fairly equal among the different species, the induction of rat hepatic CYP2E1 by arecoline suggests that there is a risk of metabolic interaction among the substrate drugs of CYP2E1 in betel-quid use human.
ABSTRACT
Objective To evaluate the clinical value of noninvasive positive-pressure ventilation (NPPV) treatment in acute respiratory distress syndrome caused by acute pancreatitis. Methods A retrospective study of 27 cases, with acute respiratory distress syndrome (ARDS) caused by acute paucreatitis,who were admitted to our department from Jan 2007 to May 2010 and treated with NPPV, was performed. The changes of heart rate, respiratory rate, PaO2, oxygenation index (OI) and PaCO2 before and after treatment were compared. Results The heart rate, respiratory rate of 25(92.6％ ) patients decreased from (118.4 ±13.4)/min, (32.1 ± 1.7)/min to ( 81.9 + 8.5 )/min, ( 19.9 ± 2.1 )/min; PaO2, OI and PaCO2 increased from (74.1 ±5.0)mmHg, (148.2 +10.0)mmHg, (28.7 ±1.6)mmHg to (110.4 ±20.8)mmHg, (204.5±71.1)mmHg, (38.4 +3.6)mmHg 48 h after NPPV, respectively, and they recovered and were transited to oxygen supply by Venturi mask. 2 (7.4％) patients deteriorated and were transited to invasive positive-pressure ventilation support. Conclusions NPPV could effectively improve oxygenation of patients with ARDS caused by acute pancreatitis. The procedure of NPPV is relatively easy to use and to learn with few complications, and worth of clinical application.
ABSTRACT
Objective To explore the efficacy and safety of low dose dopamine combined with phentolamine in the treatment of primary nephrotic syndrome (PNS) with edema. Methods Retrospective control studies were performed in 155 patients of PNS with edema, who received comprehensive treatment with small dose dopamine combined with phentolamine (group A). Patients treated with furosemide infusion were recruited as control (group B). Results The urinary output, urinary sodium increased after therapy in group A, showing significant differences (P ＜ 0. 01). But urinary potassium excretion, serum sodium and potassium showed no significant difference after therapy in group A. The urinary output, urinary sodium and potassium excretion increased and the serum sodium and potassium decreased after therapy in group B, all showing significant differences between before and after treatment (P ＜0. 01). The edema relief rate,urinary output, urinary sodium excretion, serum sodium and potassium in group A was significantly higher whereas urinary potassium excretion were significantly lower than those of group B(P ＜0. 01). The rate of drug adverse reaction in group A was significantly lower than that of group B. Conclusion Low dose dopamine combined with phentolamine in PNS with edema is safe and effective,which may be a substitute of diuretic like furosemide in the treatment of edema of patients with different blood volume.
ABSTRACT
Objective To investigate the efficacy of laboratory tests in the renal damage early diagnosis of children with Henoch-Schoalein purpura (HSP) and clinical effect of early intervention.Methods For the 143 HSP patients with normal repeated urine routine test findings,renal function biomarkers including urinary proteins ( immunoglobulin G (IgG),micro-albumin ( MA ),transferrin (TRF),a1 -microglobulin ( α1 -MG),β2-Microglobulin (β2-MG) ) and urinary enzymes ( N-acetyl-beta-D-glucosaminidase ( NAG ),γ-glutamyltransferase (y-GT) ) were detected to investigate the details of renal function changes.One hundred and thirty-one HSP patients,who had abnormal laboratory test findings of renal function biomarkers mentioned above,were randomly divided into control group ( n =65 ) and intervention group ( n =66 ),and both groups received comprehensive treatment including cimetidine,loratadine and calcium agents.However,66 patients in intervention group received low-dose heparin via micropump-based continuous intravenous infusion and regular oral diammonium glycyrrhizinate treatment.Sixty-five patients were enrolled in control group,without further treatment.Results Among the 143 patients with normal urine routine examination,131 cases (91.61％ ) had abnormal findings of renal function biomarkers.After therapy either for 2 months or 4 months,urine protein and urine enzymes were lower than before treatment,and the difference was significant (P ＜ 0.01 ).In the control group only β2-MG,NAG,γ-GT3 indexes significantly lowered at the end of 2 months ( P ＜0.01 ),and all parameters were significantly decreased at the end of 4 months ( P ＜0.01 ).Furthermore,Intervention group had lower levels of renal function biomarkers at the end of 2 months or 4 months,as compared with the control group,showing significant difference ( P ＜0.05 or P ＜0.01 ).Urinary IgG,MA,TRF,NAG recovered rapidly in the intervention group after 4 months and almost returned to the normal,but urinary α1-MG,β2-MG,γ-GT recovered slowly and still remained abnormal after 4 months due to the varying severity.After treatment for 4 months,the rate of urine testing abnormalities was higher in the control group than in the intervention group (36.92％ vs 6.10％ ),and the difference was significant (P ＜0.05).Conclusion Combined detection of renal function biomarkers is helpful for early diagnosis of renal damage in HSP patients.Early intervention with heparin and diammonium glycyrrhizinate can prevent kidney damage,delay disease progress.Early diagnosis and early intervention should be emphasized for the treatment strategy of the renal damage of children with HSP.
ABSTRACT
ObjectiveTo determine the risk factors and the optimal management of hepatic artery complications (HAC) after orthotopic liver transplantation.MethodsThe clinical data of 180 orthotopic liver transplantation patients performed between January 2005 and September 2007 was reviewed.The incidence of HAC between primary liver carcinoma and benign diseases of liver was compared.ResultsTwelve (6.7％) episodes of HAC were identified.3 were hepatic artery thrombosis (HAT) and 9 were hepatic artery stenosis (HAS).The incidence of HAC in patients with primary liver carcinoma (6/39) was higher than benign disease (6/141)(P＜0.05).ConclusionsThe keys to management of HAC after orthotopic liver transplantation are to diagnose the complication in time and to select the proper treatment based on the type of HAC.
ABSTRACT
Stroke is an important cause for childhood disability and death.Its risk factors and pathophysiological processes have significant differences with the adult patients.The common risk factors for pediatric arterial ischemic stroke (AIS) include cerebral arteriopathy,cardiac diseases,blood system and metabolic diseases,infection,and genetic factors.The clinical manifestations of AIS are different because of the age,underlying cause,and location of stroke.After a full examination,some risk factors or precipitating factors can be identified in more than 90％ of children with AIS,and thus emphasizing the importance of comprehensive diagnosis and evaluation.Although a number of clinical guidelines for pediatric stroke have been published,its evidence base is rather weak.Therefore,the present treatment mainly bases upon the expert consensus and the conclusions from the adult stroke studies.This article reviews the epidemiology,risk factors,clinical evaluation,managment and outcome of pediatric AIS.
ABSTRACT
AIM: To study the role of peroxisome proliferator-activated receptor-α (PPAR-α) signal transduction pathway in cardiac hypertrophy induced by high glucose and insulin (HGI). METHODS: The cultured neonatal rat cardiomyocytes were used to observe the effect of fenofibrate (FF), a selective PPAR-α agonist, on cardiomyocyte hypertrophy induced by HGI (glucose at concentration of 25.5 mmol/L and insulin at 0.1 μmol/L). The cardiomyocyte hypertrophic responses were assayed by measuring the cell surface area, protein content, and mRNA expression of atrial natriuretic factor (ANF). The expressions of mRNA and protein were assayed by real -time PCR and Western blotting. RESULTS: In cultured cardiomyocytes, HGI induced profound change of hypertrophic morphology, the significant increase in cell surface area, protein content and ANF mRNA expression compared to those in vehicle control (P<0.01), but the expressions of PPAR-α mRNA and protein decreased significantly (P<0.05). At the same time, the expression of cyclooxygenase 2 (COX-2), one of the PPAR-α downstream effectors was obviously elevated (P<0.05). However, FF (0.1, 0.3 and 1 μmol/L) inhibited the cardiomyocyte hypertrophy induced by HGI in a concentration-dependent manner (P<0.01). FF at concentration of 0.3 μmol/L increased the expressions of PPAR-α in both mRNA and protein levels (P<0.05) and inhibited the expressions of COX-2 (P<0.05), which were abolished by MK 886 (0.3 μmol/L), a selective PPAR-α antagonist (P<0.05). CONCLUSION: PPAR-α signal transduction pathway and its downstream effector COX-2 might involve in the cardiomyocyte hypertrophy induced by HGI.
