Pediatric kidney disease prevalence has increased over the past decades.The key result of children with chronic kidney disease (CKD) is end-stage renal disease (ESRD) who needs renal replacement therapy with significantly increased risk of cardiovascular disease and metabolic syndrome.It is essential to diagnose CKD in the early phase by assessment of kidney function.We assess the kidney function by detecting serum creatinine(SCr) and blood urea nitrogen(BUN),which are traditional biomarkers and not sensitive to diagnose AKI.We also use cystatin C and β2-microglobulin to evaluate kidney function,which are controversial in clinic.It is difficult to evaluate kidney function exactly for children because glomerular filtration rate(GFR) is different in children with different age and gender.It should be more sensitive and specific to assess pediatric kidney function by applying blood and urine biomarkers and GFR equation together.Nowadays,we should find a more precise equation to evaluate GFR for children in order to monitor the kidney disease progression.It may provide the exact timing for the treatment to prevent ESRD.Therefore,we summarize some GFR equations in order to detect more suitable equation to evaluate GFR for Chinese children with different age,gender and nutrition status.

Small for gestational age (SGA) infants are defined as infant with a birth weight below the 10th percentile of the average weight for gestational age or below 2 standard deviations for gestational age.More evidences have suggested that compared with the appropriate for gestational age infants,besides the short stature,there are also higher risks of lower intelligence,poor academic performance,low social competence,behavioral problems in SGA infants.

Objective To investigate the clinical efficacy of laparoscopic myomectomy surgery and open myomectomy surgery for the patients with uterine fibroids.Methods 78 patients with uterine fibroids in our hospital were divided into observation group and control group by random serial number,and each group had 39 cases.The observation group was given laparoscopic myomectomy,while the control group was given open myomectomy surgery.The average time,average blood loss,postoperative exhaust time and average postoperative hospitalization days were compared between the two groups.Results The operative time,blood loss,postoperative exhaust time and hospital stay time of the observation group were (113.3 ± 15.1) min,(50.5 ± 27.5) ml,(19.5 ± 5.1) h and (4.6 ± 0.5) d,while those in the control group were (61.5 ± 12.7) min,(100.9 ± 35.7) ml,(37.6 ± 4.9) h and (7.7 ± 0.6) d,the differences were significant between the two groups (t =11.79,10.35,8.06,7.11,all P ＜ 0.05).Conclusion Compared with open myomectomy surgery,laparoscopic myomectomy can not only shorten the hospital stay,but also reduce the time of discharge,and it is worth to be further promoted in clinical.

Ki-67,as one kind of nucleoantigen expressed in proliferated cells, has positive correlation with clinical stage, nodal status and Her-2,while negative correlation with estrogen receptor(ER). High Ki-67 expression influnced by endocrine therapy and chemotherapy indicates good proliferative activity. Ki-67, also as an independent prognostic factor of early breast cancer, provides prognostic information combined with other biologic markers. Ki-67 gives additional information breast cancer prognosis staging.

Kawasaki disease (KD) is an acute, self-limited vasculitis of children and the principal cause of acquired heart disease in children in developed countries. The recent follow-up studies of KD revealed that cardiac sequelae had been observed for many years in a minority of patients with KD. Cardiac sequelae especially the coronary artery aneurysm is the leading cause of ischemic heart disease or even the sudden death.The long-term management of KD was developed in many countries in order to prevent the cardiac events.This paper reviews the long-term prognosis and follow-up of KD.

ObjectiveTo investigate the value of serum β2-microglobulin for diagnosis of early renal insufficiency. MethodsThe levels of β2-microglobulin and Scr were measured in one hundred and twelve patients diagnosed of nephropathy and 41 of control group.And the results were analyzed. ResultsCompared with the control group,there was significant difference in serum β2-microglobulin(all P＜0.05).The levels of β2-microglobulin of renal insufficiency were increased,include(3.51 ± 0.46)mg/L,(5.8 ± 1.13)mg/L,(12.4 ± 3.63)mg/L,and (21.3 ± 4.73)mg/L,also correlated with degree of Scr,and negatively correlated with degree of Ccr. ConclusionSerum β2-microglobulin could be used as the early diagnostic marker of early renal insufficiency.

Objective:To establish an HPLC method for the determination of two ingredients in losartan potassium and hydrochlo-rothiazide tablets. Methods: Losartan potassium and hydrochlorothiazide were separated on a Zorbax Eclipse XDB-C8 ( 200 mm × 4. 6 mm, 5 μm)column, the mobile phase consisted of 0. 01 mol·L-1 monopotassium phosphate solution(adjusting pH to 3. 0 with phosphoric acid)-acetonitrile(70∶30)with the flow rate of 1. 0 ml·min-1. The column temperature was set at 35℃, the detection wavelength was 271nm and the injection volume size was 20 μl. Results:The linear range of losartan potassium and hydrochlorothiaz-ide was 39.63-118.89 μg·ml-1(r=0.999 9) and 9.47-28.41 μg·ml-1(r=0.999 6) with the average recovery of 99.4%(RSD=1. 0%,n=9)and 99. 8%(RSD=0. 9%, n=9), respectively. Conclusion: The method is simple, fast, accurate and reproduci-ble, which is suitable for the determination of losartan potassium and hydrochlorothiazide tablets.

Henoch-Schonlein purpura (HSP) is the most common form of childhood autoimmune vascular inflammatory diseases,the incidence rate showed an increasing trend,its pathogenesis has not yet been fully elucidated.Thl7 cells are recently discovered to be a new kind of different from Th1,Th2 effector of CD4+ T cell subsets,Th17/Treg imbalance is closely related to the pathogenesis of HSP.The paper reviewed the related researches.

Objective:To investigate the effect of curcumin on the proliferation and the protein expression of Pleiotrophin(PTN) in cervical cancer Caski cells. Methods:MTT was used to assay the proliferation of Caski cells which were treated with different concentrations of curcumin. The immunocytochemistry was used to assay the distinctive expression of PTN in Caski cells which were treated by curcumin or not. The effects of curcumin with different concentrations on the protein levels of PTN were tested by Western blotting. Results:The proliferation of Caski cells were inhibited by curcumin in a does-dependent manner.Immunocytochemistry assessment showed the expression of PTN was significant down-regulated after treated with curcumin. Western blotting showed the curcumin could down-regulate the expression of PTN,and this was a does-dependent action. Conclusion:Curcumin could inhibit the proliferation and the PTN expression of Caski cells significantly,which may be one of the molecular mechanisms anticancer of curcumin.

Objective To investigate the value of serum apolipoprotein M (APOM)concentration in the diagnosis of bacterial pneumonia and its disease severity evaluation.Methods The serum APOM concentration was examined in 250 cases of pneumonia and 50 healthy controls by using the double antibody sandwich ELISA.The ROC curve was used to evaluate the diagnostic value of APOM on bacterial pneumonia and the Bayes discriminant analysis was adopted to construct the discriminant equation based on APOM concentration for evaluating its discriminant significance to the disease severity.Results The serum APOM concentration in the bacterial pneumonia group was (28.9±10.5)μg/mL,which was significantly higher than (19.4±8.93)μg/mL in viral pneu-monia group,(16.4±5.62)μg/mL in the other pneumonia group and(18.1 ±6.15)μg/mL in the healthy controls,the differences had statistical significance(P <0.01).The area under ROC curve for APOM in diagnosing bacterial pneumonia could reach 0.843, showing the good sensitivity and specificity.Moreover,the serum APOM concentration was positively correlated with the disease severity of bacterial pneumonia.The discriminant equation based on APOM concentration as well as sex,age,systolic pressure,body temperature and heart rate could better conduct the classification on the disease severity of bacterial pneumonia and its accuracy could reach to 86.7%.Conclusion The serum APOM concentration has an important clinical value for the diagnosis of bacterial pneumonia and its disease severity evaluation.
