ABSTRACT

Objective:To investigate the renal protective effect of Tangshenping capsule (Tangshenping) on diabetic nephropathy (DN) KKAy mice and its effect on Wnt/β-catenin signaling pathway. Method:Sixty female Sprague-Dawley KKAy mice aged 10 weeks old were induced with KKAy rat feed for 10 weeks. The DN animal model was successfully determined with blood glucose (>16.7 mmol·L-1) and 24 hour urine protein (>0.4 mg). The model mice were randomly divided into a model group, an irbesartan group, and low, medium and high-dose Tangshenping group, with 10 female C57BL/6J mice as a control group. The treatment groups were given the corresponding drugs by gavage. The normal group and the model group were given an equal volume of deionized water by gavage. The intragastric dose was 0.01 mL·g-1 body weight coefficient once a day. The general conditions of the mice were observed, the body mass was weighed every 4 weeks, and 24 h urine protein was quantified. At the 26th week, the blood was collected from eyeballs, and the mice were put to death. The quality of the kidneys, serum blood urea nitrogen (BUN), serum creatinine (SCr), triglyceride (TG), malondialdehyde (MDA), nitric oxide (NO) and superoxide dismutase (SOD) content were measured. In situ hybridization and immunohistochemistry were used to detect the expressions of Wnt4, glycogen synthase kinase 3β(GSK3β) and β-catenin in kidney tissues. Result:Compared with model group, body mass, kidney mass/body mass, and 24 h urine protein were significantly lower in high-dose Tangshenping group (PPPβ and β-catenin were decreased (PConclusion:Tangshenping may inhibit the activation of Wnt/β-catenin signaling pathway, reverse the transdifferentiation of renal tubular epithelial cells in DN KKAy mice, delay the progression of renal interstitial fibrosis, and then exert renal protection.

ABSTRACT

Objective To analyze clinical characteristics of severe community-acquired pneumonia during pregnancy and its outcomes, and to explore the relevant risk factors. Methods From September 2012 to September 2017,324 398 pregnancies admitted in 7 tertiary hospitals were included. Clinical data of 33 cases of pregnancies with severe community-acquired pneumonia(severe pneumonia group)and 214 cases of pregnancies with common community-acquired pneumonia (control group) were reviewed retrospectively, including the clinical information, manifestations, laboratory examinations and pregnancy outcomes. Relevant risk factors were analyzed by multivariate logistic regression analysis. Results (1) General data: pregnancies with severe community-acquired pneumonia accounted for 0.010%(33/324 398) of hospitalized pregnancies, the gestational age of two groups were(28±8)and(23±8)weeks, body mass index were(21.7±2.1)and(25.5±3.4)kg/m2, rate of low income were 54.5%(18/33)and 31.8%(68/214), respectively. The differences between two groups were all statistically significant(all P<0.05). No significant differences were found in age, pregnancy and parity times, rate of main pregnant complications such as diabetes and hypertension, educational level, asthma and onset seasons between two groups(all P>0.05). (2)Clinical data: the severe pneumonia group had significantly higher incidence of fever [100.0%(33/33)vs 75.2%(161/214)], shortness of breath(90.9% vs 16.8%)compared with the control group(all P<0.05).The median peripheral leukocytes counts were 12.3×109/L and 10.2×109/L, the hemoglobin level were(84±18) and(107±14)g/L,the albumin level were(26±4)and(37±3)g/L, the median serum urea nitrogen level were 3.7 and 2.4 mmol/L,the serum creatinine level were(72±25)and(45±11)μmol/L, respectively in two groups. The differences were all statistically significant (all P<0.05). No significantly statistical differences were found in coagulation indicator and cardiac function between two groups(all P>0.05).(3) Treatments: in severe pneumonia group, 12 patients(36.4%,12/33)needed invasive mechanical ventilation, 9 patients(27.3%,9/33)needed non-invasive mechanical ventilation, average time of mechanical ventilation was(7±4)days;8 patients(24.2%,8/33)with septic shock needed vasoactive drugs. However, there was no patient in control group needing mechanical ventilation and vasoactive drugs.(4)Pregnant outcomes: one patient(3.0%,1/33)died in the severe pneumonia group, while no death occurred in the control group. The hospital stay between two groups were(15.1±4.1)and(7.0±1.9)days, the rates of abortion and stillbirth between two groups were 42.4%(14/33)and 3.3%(7/214), the rates of premature were 10/19 and 6.3% (13/207), the rates of cesarean were 15/19 and 43.0%(89/207), the rates of low birth weight newborn were 17/19 and 14.0%(29/207), the rates of infected newborn were 15/19 and 10.1%(21/207), the birth weights were(2 165±681)and(3 102±400)g, respectively. The differences between two groups were all statistically significant(all P<0.05).(5)Multivariate logistic regression analysis demonstrated that anemia, low body mass index, hypoproteinemia were risk factors for severe pneumonia in pregnancy(all P<0.05). Conclusions Pregnancy with severe community-acquired pneumonia may be complicated by multiple organ dysfunctions, lead to adverse outcomes. Anemia, malnutrition are risk factors for pregnancy with severe pneumonia. Active and effective treatment may improve its prognosis.

ABSTRACT

A new species of genus shewarella Shewanellade decolorations S12, was isolated from activated sludge of a textile-printing waste-water treatment plant. In the anaerobic condition, S12 could conserve energy for growth by using Fe3 + as the terminal electron acceptor. At the optimal condition of pH8, temperature 30℃, ferric citrate 800mg/L, sodium lactate 2g/ L, yeast extract 0. 5g/ L , the cell growth increased with the raise of the amount of the Fe3+ reduction in 8k The effect of different carbon soucres, nitrogen sources, pH values and growth temperatures on the anaerobic Fe3 + reduction of Shewanella decolorations S12 was investigated. LB was favorable for Fe3 + reduction. Glucose and sodium lactate also were favorable for Fe3+ reduction. The cell growth and Fe3 + reduction increased with the raise of the amount of the yeast extract from 0 to 4g/L The amounts of the sodium lactate of 6g/ L and ferric citrate of 800mg/L were suitable for strain S12 growth and Fe3+ reduction. In the optimum initial pH value range of 6 -8 for Fe3+ reduction, strain S12 growth increased with the raise of the pH val- ue. Strain S12 could growth and reduce Fe3+ at the temperature range of 20 -40℃. The best temperature for strain S12 growth and Fe3 + reduction was 301.
