Objective To observe the clinical characteristics and prognosis of primary nephrotic syndrome (PNS) in the elderly. Methods The clinical and pathological features of 52 elderly patients with PNS and 64 non-elderly patients with PNS were retrospectively analyzed and compared.The elderly patients with PNS received routine treatment:oral corticosteroids prednisone 1mg·kg-1 ·d-1.After 8 weeks maintenance treatment,if symptoms were alleviated,the prednisone dose was gradually reduced to a maintenance dose, then was stopped gradually. If symptoms were not alleviated, the cyclophosphamide or cyclosporine, mycophenolate mofetil was added. Results There were significant differences in the numbers of patients complicated with hypertension, infection,chronic renal insufficiency and hematuria between the elderly group and non-elderly group (P＜0. 05＝.But there were no significant differences in the level of blood albumin, quantitative measurement of 24 hours urinary protein and incidence rate of acute renal insufficiency between the two groups (P＞0.05). The major pathological types of PNS in the elderly were membranous nephropathy (46.2 %),IgA nephropathy (23. 1 %) and focal segmental glomerulosclerosis ( 11.5 %), respectively. And the major pathological types of PNS in non-elderly group were mesangial proliferative glomerulonephritis (32.8%), IgA nephropathy ( 25.0% ) and minimal change nephropathy ( 20. 3 %), respectively.Complete remission after treatment was found in 31 patients(59.6%), partial remission in 18 cases and inefficacy in 3 cases. Conclusions The major clinicopathological type of PNS in the elderly is membranous nephropathy and should be treated using corticosteroids and immunosuppressive agents,with different effects in different pathological types.

Objective To investigate the correlation between asymmetric dimethylarginine (ADMA) and endothelial dysfunction in patients with type 2 diabetic nephropathy.Methods The 81 patients with type 2 diabetic nephropathy were selected.According to the urinary albumin excretion rate (UAER),the patients were divided into micro-albuminuria group (DN1 group,UAER 21-199 mg/24 h,38 cases) and macro-albuminuria group (DN2 group,UAER ≥ 200 mg/24 h,43 cases).The 20 healthy people were defined as control group.Intimal-media thickness and endothelial dysfunction of the radial artery of right forearm were detected by color Doppler ultrasound.The serum level of ADMA was determined by enzyme-linked immunosorbent assay.Results There was no significant difference in radial artery inner diameter intimal-media thickness among the 3 groups (P ＞ 0.05).The Endothelial dependent diastolic function (EDD) and endothelial independent diastolic function (EID) in DN1 group and DN2 group were significantly lower than those in control group [(10.45 ± 2.58)％ and (7.56 ± 2.17)％ vs.(15.72 ± 3.05)％,(15.42 ± 2.71)％ and (15.37 ± 2.92)％ vs.(19.31 ± 3.76)％,P ＜ 0.05],and the EDD in DN2 group was significantly lower than that in DN1 group (P＜ 0.05).The serum ADMA in DN1 group and DN2 group was significantly higher than that in control group [(0.63 ± 0.08) and (0.92 ± 0.12) μ mol/L vs.(0.39 ± 0.05)μmol/L,P ＜0.05],and in DN2 group it was significantly higher than that in DN1 group (P ＜0.05).In patients with type 2 diabetic nephropathy,the serum ADMA and EDD had negative correlation (r =-0.81,P =0.020),but the serum ADMA and C reactive protein had positive correlation (r =0.75,P =0.034).Conclusions The serum level of ADMA is significantly increased in patients with type 2 diabetic nephropathy.There is a close correlation between ADMA and endothelial dysfunction of artery.

Objective To investigate the prevalence features of helicobacter pylori (Hp) infection,anemia and iron deficiency in a po-pulation of Wuhan children with 2 to 6 years old,and the relationship between Hp infection and anemia,iron deficiency in the children.Methods Randomly taking 95 children who had taken tests in our hospital's check-up centre in 2008 as the study objects,2 kinds of exa-mination were employed to detect Hp infection.Serum levels of Hp-IgG were measured by enzyme linked immunosorbent assay (ELISA) methods to evaluate past infection.The 14C urea breath test (14C-UBT) was conducted to obtain information of the presence of current/active Hp infection.In the morning 3 mL fasting venous blood was collected to determine the serum levels of Hp-IgG antibodies and ferritin.Hemoglobin values were determined with a hemoglobinometer.Serum levels of C-reactive protein (CRP) were tested in order to determine whether the children had evidence of current inflammation or infection.In addition,demographic information such as age and gender of the children and information about their use of antibiotics within the prior month were recorded.All cases were divided into 2 groups including the Hp infection group and non-Hp infection group according to laboratory examinations,then the Logistic regression was applied to analyze the relationship between Hp infection and anemia,iron deficiency.The Kappa identity test was taked to compare the 2 measures.Results Of the 95 children,18.9% were anemic and 36.8% were iron deficient.Forty percent of the cohort had Hp-IgG antibodies,74.4% tested positive by the UBT.Presence of Hp-IgG emerged as a significant risk factor for anemia,iron deficiency in adjusted analysis controlling for demographic factors,current inflammation,and antibiotic use.Conclusions Findings from different measure of Hp may reflect different stages of infection,with UBT results reflecting an earlier stage of infection,and presence of Hp-IgG reflecting established Hp infection associated with anemia,iron deficiency.

OBJECTIVE: To develop a five fluorescence-labeled multiplex amplification system for 15 loci and study genetic polymorphism in Xinjiang Uygur population. METHODS: The STR loci were screened. The alleles were named according to the number of repeats by sequencing. The sensitivity, species specificity, identity and stability of the five fluorescence-labeled multiplex amplification system for the 15 loci were all tested. Then, the genetic polymorphism was analyzed in Xinjiang Uygur population and compared with other ethnic groups including Xizang Tibetan, Xiuyan Manchu, and Guangzhou Han population. RESULTS: The 15 loci multiplex amplification system was established. The sensitivity was 0.3 ng with good species specificity, identity and stability. The distributions of genotype for 13 STR loci in Uygur population were in accordance with Hardy-Weinberg equilibrium with no genetic linkage between these loci. Most loci showed statistically significant among different populations. CONCLUSION The established system has application value in forensic evidence. The 13 STR loci in Uygur population have

OBJECTIVETo observe the antiviral efficacy of Ganneng Dripping Pill (GDP) in treating patients with chronic hepatitis B.

METHODSEighty-four patients of chronic hepatitis B with positive HBV-DNA, HBsAg, and HBeAg were randomly assigned to 2 groups, the treated group (56 patients) treated with GDP and the control group (28 patients) treated with lamivudine. The therapeutic course for both groups was 6 months. The negative conversion rate of HBeAg and HBV-DNA, changes of liver function, symptoms and physical signs in patients were observed before and after treatment.

RESULTSIn the treated group, the negative conversion rate of HBV-DNA and HBeAg was 54.0% (27/50) and 30.0% (15/50) respectively, and the ALT normalizing rate was 80.0% (40/50), while those were 67.86% (19/28), 21.8% (6/28) and 75.0% (21/28) respectively in the control group, showing no significant difference between the two groups (all P > 0.05). However, the AST normalizing rate was 97.96% (48/49) in the treated group, higher than that in the control group (48.0%, 12/25, P < 0.01); and the clinical symptoms, especially the poor appetite, lassitude, gastric distention and yellow urine, were improved more significantly in the treated group than those in the control group (P <0.05 or P < 0.01).

CONCLUSIONGDP has a favorable short-term effect on chronic hepatitis B, it could effectively inhibit HBV replication and improve the liver function, symptoms and signs in patients.

Objective To investigate the correlation between asymmetric dimethylarginine (AD-MA) and endothelial dysfunction in patients with uremia.Methods Uremic patients who did not receive hemodialysis were defined as A group (n =40) ; uremic patients who had received hemodialysis were divided into B group (n =45) ;healthy people were defined as C group (n =20) ;and chronic kidney disease (stage 2 ～ 4) patients were defined as D group (n =20).The diameter of intima-media thickness,and endothelium-dependent or independent dilation (EDD or EID) of radial artery in right forearm were detected with diasonography.The levels of ADMA were determined by high-performance liquid chromatography.Results Compared to C group,the levels of ADMA in A,B and D groups were significantly increased [C:(0.78 ±0.19) μmol/L,A:(1.51 ±0.16) μ mol/L,B:(1.13 ±0.14) μmol/L,D:(0.92 ±0.11) μmol/L; P ＜0.05].Compared to A group,the levels of ADMA were significantly decreased in B group (P ＜0.05).EDD and EID were decreased significantly in A,B and D groups compared to C group [EDD:C:(13.52±1.73)％ vs A:(7.32 ±0.54)％,B:(9.02 ±0.86)％,D:(10.13 ±1.25)％,P ＜0.05;EID:C:(14.45±1.85)％ vsA:(10.37 ±1.51)％,B:(9.54±1.39)％,D:(11.17±1.56)％,P ＜0.05].EDD in B group was significantly lower than A group (P ＜0.05).In group A,a negative correlation was found between EDD and the level of ADMA (r =-0.81,P =0.020).Conclusions ADMA level was significantly increased in uremic patients.A close correlation existed between ADMA and endothelial dysfunction of radial artery.

BACKGROUND: This study aimed to observe the effect of early goal directed therapy (EGDT) on tissue perfusion, microcirculation and tissue oxygenation in patients with septic shock. METHODS: Patients with early septic shock (<24 hours) who had been admitted to the ICU of Zhongda Hospital Affiliated to Southeast University from September 2009 through May 2011 were enrolled (research time: 12 months), and they didn't meet the criteria of EGDT. Patients who had one of the following were excluded: stroke, brain injury, other types of shock, severe heart failure, acute myocardial infarction, age below 18 years, pregnancy, end-stage disease, cardiac arrest, extensive burns, oral bleeding, difficulty in opening the mouth, and the onset of septic shock beyond 24 hours. Patients treated with the standard protocol of EGDT were included. Transcutaneous pressure of oxygen and carbon dioxide (PtcO2, PtcCO2) were monitored and hemodynamic measurements were obtained. Side-stream dark field (SDF) imaging device was applied to obtain sublingual microcirculation. Hemodynamics, tissue oxygen, and sublingual microcirculation were compared before and after EGDT. If the variable meets the normal distribution, Student's t test was applied. Otherwise, Wilcoxon's rank-sum test was used. Correlation between variables was analyzed with Pearson's product-moment correlation coefficient method. RESULTS: Twenty patients were involved, but one patient wasn't analyzed because he didn't meet the EGDT criteria. PtcO2 and PtcCO2 were monitored in 19 patients, of whom sublingual microcirculation was obtained. After EGDT, PtcO2 increased from 62.7±24.0 mmHg to 78.0±30.9 mmHg (P<0.05) and tissue oxygenation index (PtcO2/FiO2) was 110.7±60.4 mmHg before EGDT and 141.6±78.2 mmHg after EGDT (P<0.05). The difference between PtcCO2 and PCO2 decreased significantly after EGDT (P<0.05). The density of perfused small vessels (PPV) and microcirculatory flow index of small vessels (MFI) tended to increase, but there were no significant differences between them (P>0.05). PtcO2, PtcO2/FiO2, and PtcCO2 were not linearly related to central venous saturation, lactate, oxygen delivery, and oxygen consumption (P>0.05). CONCLUSION: Peripheral perfusion was improved after EGDT in patients with septic shock, and it was not exactly reflected by the index of systemic perfusion.

Objective To explore the protection of valsartan combined with simvastatin on kidney in early diabetic nephropathy rats. Methods Diabetic nephropathy rats model were induced by streptozocin (STZ) ,the experimental rats were randomly divided into 5 groups: control (group C), diabetic nephropathy (group D) ,diabetes treated with valsartan (group X) ,diabetes treated with simvastatin (group Z) ,and diabetes treated with combined valsartan and simvastatin ( group L). Blood glucose (BG), HbA1c, blood cholesterol ( TC), trigalloylglycerol ( TG ), blood ureanitrogen ( BUN ), serum creatinine (SCr) , urinary albumin excretion rate (UAER) were measured, and the podocyte ultrastructure was observed by transmission electronic microscopy. Results The levels of BG, HbA1c,TC,TG and UAER in group D increased significantly compared togroup C(BG:[20.3 ±3.2]mmol/L vs [6.1 -±0. 4]mmol/L;HbA1c:[7.18 ±0.47]% vs [3.37 ±0. 15]% ;TC: [2. 69 ±0. 35] mmol/L vs [1.28 ±0. 24] mmol/L;TG: [3.09 ±0. 37] mmol/L vs [1.18 ±0. 25]mmol/L) (P ＜ 0. 05 ). Creatinine clearance rates (Ccr) in group D ( [0. 89 ± 0. 19] ml/min ) decreased significantly compared to group C( [1.27 ±0. 33] ml/min) ,as well as group X,Z and L( Ps ＜ 0. 05 ). UAER in group D was significantly higher than that in group C ( [19. 87 ±3. 85] μg/24 h vs [3. 67 ± 1.01] μg/24 h) (P ＜ 0. 05 ), as well as group X, Z and L ( P ＜ 0. 05 ), and the improvement in group L was particularly significant ( P ＜ 0. 05 ). The projections of podocyte in group D severely syncretized, there were slightly improvement in group X, Z and L compared to group D, and the improvement in group L was remarkable. Conclusion The treatment with valsartan, simvastatin and their combination will effectively protect the kidney in early diabetic nephropathy rats,and the effect of using the combination therapy is much better.
