Objective To investigate the clinical efficacy of nephrotic syndrome in children adjunctively treated by underatured lactalbumin.Methods Thirty-six cases of nephrotic syndrome were studied for about 1 year.The changes in red blood cells of reduced glutathione(GSH) were analyzed in 18 cases of underatured lactalbumin treatment group and 18 cases of control group.The clinical presentations were observed in both groups.Results GSH levels increased in underatured lactalbumin treatment group when compared with control group.The frequency of relapse and upper respiratory tract infection in underatured lactalbumin treatment group were significantly reduced compared with control group.Conclusion Underatured lactalbumin can provide support for the potential use of an antioxidant therapy in these patients.

ObjectiveTo investigate the extracorporeal clearance rate of imipenem in severe infection patients in the mode of continuous vena-venous hemofiltration (CVVH) during continuous renal replacement therapy (CRRT), in order to approach if the concentration of imipenem in plasma could achieve effective levels of anti-infection, and to explore the effect of time and anticoagulation measure on imipenem clearance during CRRT treatment.Methods A prospective observational study was conducted. All adult severe infection patients complicating acute kidney injury (AKI) in the Department of Critical Care Medicine of the Fourth Hospital of Hebei Medical University from March 2013 to September 2014, who were prescribed imipenem as part of their required medical care, and CRRT for treatment of AKI were enrolled. 0.5 g doses of imipenem was administered intravenously every 6 hours or 8 hours according to random number table, and infused over 0.5 hour. The unfractionated heparin was used for anticoagulation in the patients without contraindications, and no anticoagulation strategy was used in the patients with high risk of bleeding. At 24 hours after first time of administration, postfilter venous blood and ultrafiltrate samples were collected at 0, 0.25, 0.5, 0.75, 1, 2, 5, 6, and 8 hours after imipenem administration. The concentration of imipenem in above samples was determined with liquid chromatography-mass spectrometer/mass spectrometer (LC-MS/MS).Results A total of 25 patients were enrolled. Thirteen patients received imipenem intravenously every 6 hours, and 12 patients, every 8 hours. The anticoagulation was conducted with heparin in 13 cases, and 12 cases without anticoagulation. The intra-day precision, inter-day precision, matrix effect, and recovery rate in low, medium, and high concentration of plasma and ultrafiltrate, and the stability of samples under different conditions showed a good result, the error of accuracy was controlled in the range of±15%. With the application of Prismaflex blood filtration system and AN69-M100 filter, under the mode with CVVH, the total clearance rate of imipenem was (8.874±2.828) L/h when the actual dose of replacement fluid was (31.63±1.48) mL·kg-1·h-1, the total CRRT clearance rate of imipenem in vitro was (2.211±0.539) L/h, which accounting for (30.1±15.7)% of the total drug clearance. In 6 hours interval dosage regimen, the percentages of the time> 4×minimum inhibitory concentration (MIC) at specific 4×MIC of 2, 4, 6, and 8μg/mL of imipenem were more than 40% of the dosing interval. But in the 8 hours interval dosage regimen, when the level was above the 4×MIC of 4μg/mL, maintaining time would drop below 40% of the dosing interval, with significant differences compared with that in 6 hours interval dosage regimen [4×MIC = 2μg/mL: (60.84±20.25)%vs. (94.01±12.46)%,t = 4.977,P = 0.001; 4×MIC = 4μg/mL: (39.85±15.88)% vs. (68.74±9.57)%,t = 5.562, P = 0.000; 4×MIC = 6μg/mL: (27.58±13.70)% vs. (53.97±8.36)%,t = 5.867,P = 0.000; 4×MIC = 8μg/mL:(18.87±12.43)% vs. (43.48±7.83)%,t = 5.976,P = 0.000]. No significant change in sieving coefficient of imipenem was found within a short time (6 hours), which indicated that there was no effect of anticoagulation on clearance of imipenem by AN69-M100 filter, and no statistical significance was found with repeated measure analysis (F = 0.186, P> 0.05).ConclusionsThe clearance rate of imipenem is increased significantly in vitro under the mode of CVVH with the actual dose of replacement fluid was (31.63±1.48) mL·kg-1·h-1 in severe infective patients with severe sepsis complicating AKI, affecting the level of plasma drug concentration, need to adjust the dosage regimen. When the time of the dosing interval was shortened, the concentration of imipenem in patients' plasma could be increased significantly. In a short period of time, the sieving coefficient of imipenem through AN69 filter is not affected by anticoagulation measures and time cleaning efficiency will not decline.

Objective To study the value of lung window and soft tissue window in measuring colon diseases with experimental CTVC examination.Methods Twenty-four artificial polypoid diseases were placed with glue in a thoroughly cleaned porcine colon(overall length,150 era)that was distented with air and submerged in a water phantom and scanned 10 times on a 64-MSCT(GE Light speed)with identical scanning parameters.The data were reconstructed every 0.625 mm and reviewed using 2D images, navigation,MPR and 3D volume-rendered images on a GE AW 4.2 workstation.The maximum diameters of the artificial polypoids were measured by two radiologists with more than 10 years working experience in lung window(W = 1000,L =-700)and soft tissue window(W =400,L =40),respectively.The average value of maximum diameters of the artificial polypoids were measured for 10 times and were compared with the actual diameter.Results Twenty-four artificial polypoid diseases and their shape,size,loeation and relation of diseases with bowel wall were all showed excellently.The maximum diameter measured was close to the actual diameter.The average value was mostly less than actual diameter and a few of them more than the actual diameter.The maximum diameter measured in lung window was close to the actual diameter,and there was no difference between the two data sets(t =0.431,P =0.669).There was difference between the maximum diameter measured in soft tissue window and the virtual diameter(t = 2.691,P = 0.010). Conclusion In screening the colon diseases,CTVC is a good method of choice with no insult or less insult, and higher repeatability.The lung window should be chosen in measuring colon diseases in CTVC examination.

Objective To study the state of erythrocyte immune function in neonates with hyperbilirubinemia,and analyze the influence of various clinical status on erythrocyte immune function.Methods Fifty-two neonates with hyperbilirubinemia were enrolled and 104 healthy neonates as the control group.The adherence rate of complement 3b-receptor on the surface of red blood cell(RBC-C3bRR) and the immune complex adherence rate of red blood cell(RBC-ICR) were detected with erythrocyte saccha-romycete rosettet test.Results 1.The level of RBC-C3bRR in neonates with hyperbilirubinemia was lower than that in control group,and the level of RBC-ICR in neonates with hyperbilirubinemia was higher than that of control group(Pa0.05).3.Comparing the neonates with unconjugated bilirubin of different concentrations,there were significant difference in RBC-ICR(Pa0.05).4.There were positive correlation between RBC-ICR and bilirubin,unconjugated bilirubin in the neonates(Pa0.05).Conclusion Erythrocyte immune function in neonates with hyperbilirubinemia is obviously lower than that of control group and it is influenced by the concentratron of bilirubin and the time of phototherapy.

Objective To explore the correlation between hyperlipidemia and colorectal polyps by compare the level of serum lipids in patients with colorectal polyps.Methods The levels of total cholesterol (TC),triglyceride (TG) and low density lipoprotein-cholesterol (LDL-C) of 159 patients with colorectal polyps and 138 controls were tested.The serum lipids between colorectal polyps group and control group,of colorectal polyps with different pathological type,of adenomatous polyps with different pathological type,of adenomatous polyps with different location,colorectal polyps of different gender were compared.Chi square test or t test were performed for data analysis.Results The incidence of hyperlipidemia of colorectal polyps group was 41.5％ (66/159),which was higher than that of control group (16.7％,23/138) and the difference was statistically significant (x2 =36.56,P＜0.01),its levels of TG,TC and LDL-C were all higher than those of the latter ((1.52±0.56) mmol/L vs (1.06 ± 0.42) mmol/L,(5.22±0.86) mmol/L vs (4.52±0.96) mmol/L,(2.85±0.66) mmol/L vs (2.52± 0.35) mmol/L; t=4.23,4.02,3.72,all P＜0.01).There were no significant differences in the levels of TC,TG and LDL-C between colorectal polyps with different pathological type (all P＞ 0.05).The incidence of hyperlipidemia of tubular villous adenoma and villous adenoma (progressive adenomas) was 60.0％ (15/25),which was higher than that of tubular adenoma group (33.3％,20/60) and the difference was statistically significant (x2=5.18,P＜0.05).The incidence of hyperlipidemia of left colon and rectal polyps group was 46.2％ (49/106),which was higher than that of right colon polyps group (28.6 ％,12/42) and the difference was statistically significant (x2 =3.87,P＜0.05).The incidence of hyperlipidemia of male colorectal polyps group was 47.2％ (51/108),which was higher than that of female group (29.4％,15/51) and the difference was statistically significant (x2 =4.53,P＜0.05).The level of TG of male colorectal polyps group was higher than that of female group ((1.84 ± 0.73) mmol/L vs (1.55±0.65) mmol/L) and the difference was statistically significant (t=3.98,P＜0.05).Age (r=0.766,P=0.009),TG level (r=0.535,P=0.012) and TClevel (r=0.688,P=0.025) were positively correlated with genesis of colorectal polyps.Conclusion There is a significant correlation between hypertriglyceride,hypercholesteremia and colorectal polyps.

Objective To study the expression of Ca-A/K channel-related molecules glutamate receptor 2 and 1(GluR2/1) in hippocampus tissues of neonatal rats with hypoxic-ischemic brain damage (HIBD). Methods A total of 60 7-day-old Sprague-Dawley rats were randomly divided into sham operation group and HIBD group. Hippocampal tissues were obtained at 0 h, 1 h, 6 h, 24 h, 48 h and 72 h after HIBD. The expression of GluR2, GluR1 and autophagy marker protein Beclin-1, LC3 were detected by Western blot assay. Results Edema and focal softening and necrosis were observed 6 h after HIBD in the brains of neonatal rats. Compared with Con group, at each time point, the expression levels of GluR2 were lower while the levels of GluR1, Beclin-1 and LC3 were higher significantly in HIBD group (P<0.05). The protein levels of LC3, Beclin-1, GluR1 and GluR2 in hippocampus tissues of HIBD group were significantly different among different time points after the estab-lishment of HIBD model (F=10.65~701.14, P<0.01). The protein level of GluR2 was decreased from 1 h to 24 h after HIBD and reached the lowest level at 24 h. The levels of GluR1, Beclin-1 and LC3 were increased at 6 h, plateaued at 24 h and remained there until 48 h. The levels of these proteins returned back to the initial level at 72 h. Conclusions Ca-A/K channel-related mol-ecules GluR2 and GluR1 play important roles in the autophagic cell death of hippocampus tissues in neonatal rats with hypoxic-ischemic brain damage.
