Jaundice is a common clinical problem in neonatal period.Phototherapy is a common treatment for neonatal jaundice, but it also has side effects such as fever, diarrhea, rash and so on.In recent years, probiotics have been widely used in neonates with jaundice because they are beneficial to the health of the host, especially when they are treated with light and probiotics are added at the same time, which is more conducive to the elimination of jaundice.Studies have shown that abnormal bilirubin metabolism is closely related to microecology.This article reviews the mechanism and clinical application of probiotics in adjuvant treatment of neonatal jaundice.

BACKGROUND:Previous studies have shown that continuous administration of 1×107 of bone marrow mesenchymal stem cel s can induce immune tolerance in rats undergoing kidney transplantation, but it is not yet found clinical y that curcumin exerts an on immunomodulatory effect on kidney transplantation.
OBJECTIVE:To investigate the effects of different concentrations of curcumin on bone marrow mesenchymal stem cel s-induced immune tolerance in rats after kidney transplantation.
METHODS:Rat model of kidney transplantation was made, and rat models were randomly divided into four groups:transplantation group with no treatment;bone marrow mesenchymal stem cel s group (cel group) injected with 1×107/kg bone marrow mesenchymal stem cel s via the left iliac vein (before peritoneal suture) and tail vein (from the 2nd day) for 10 days;bone marrow mesenchymal stem cel s+low/high dosage of curcumin groups (low/high dosage curcumin groups) injected intragastrical y with 2 or 10 mg/kg curcumin combined with injection of bone marrow mesenchymal stem cel s for 10 days. Transforming growth factor-β1 protein expression in the kidney tissues was examined by immunohistochemical staining. The concentrations of interleukin-2 and interleukin-6 in serum were detected by ELISA assay.
RESULTS AND CONCLUSION:After kidney transplantation, the protein expression of transforming growth factor-β1 in renal tubular epithelial cel s and renal interstitial cel s as wel as the concentrations of interleukin-2and interleukin-6 in serum were significantly higher in the transplantation group than the other groups (P<0.05). Compared with the cel transplantation group, the protein expression of transforming growth factor-β1 as wel as the concentrations of interleukin-2 and interleukin-6 reduced significantly in the low/high dosage curcumin groups (P<0.05). These findings indicate that simultaneous administration of curcumin and bone marrow mesenchymal stem cel s can effectively inhibit immune rejection reaction and improve renal function in rats after kidney transplantation.

OBJECTIVETo investigate the expression of STAT3 and PIAS3 in the renal tissues of rats with lupus nephritis.

METHODSThe kidneys were harvested from 18-week-old female MRL/lpr mice (lupus nephritis model group) and age-matched female BALB/C mice (normal control group). The expressions of STAT3 and PIAS3 mRNA in the renal tissues were measured by real-time quantitative RT-PCR, and the protein levels of STAT3 and p-STAT3 were examined using Western blotting and immunohistochemistry. The laboratory indices and renal histopathology of the mice were also investigated.

RESULTSThe urinary protein, blood urea nitrogen (BUN) and creatinine levels were significantly higher in MRL/lpr mice than in the control mice (P<0.05). The renal histopathology of MRL/lpr mice was characterized by increased mesangiocapillary proliferation and prominent inflammatory infiltration in the tubulo-interstitium, which were absent in the kidneys of normal control mice. Compared with the control mice, MRL/lpr mice showed significantly increased STAT3 mRNA and p-STAT3 protein levels in the renal tissues (P<0.05) with significantly lowered levels of PIAS3 mRNA (P<0.01). No significant difference was noted in the total STAT3 protein levels between MRL/lpr and control mice.

CONCLUSIONMRL/lpr mice have significantly increased expressions of STAT3 mRNA and p-STAT3 protein and decreased expression of mRNA PIAS3 in the kidneys compared with BALB/C mice.

Objective To investigate the survival rate and the influencing factors in lupus nephritis (LN) patients with neuropsychiatric systemic lupus erythematosus (NPSLE). Methods Clinical characteristics and biochemical markers of 78 patients including 59 variances were analyzed. Patients were followed up from the onset of NPSLE to death. Patient survival rate was estimated by Kaplan-Meier method. Cox regression model was used to analyze influencing factors. Results Sixteen (20.5%) of 78 patients died of SLE or its complications. Infection was the main cause of death (31.3%). One-, 3-, 5- and 10-year survival rates were 83.2%, 81.7%, 76.7% and 76.7%, respectively. Hypertension (RR =6.965,95% CI:1.578-30.746, P= 0.010), pulmonary infection (RR=8.171,95% CI:1.954-34.177, P=0.004)and acute renal failure (RR=6.978,95%CI:2.063-23.609, P=0.002) were risk factors of mortality, while cyclophosphamide (CTX) impulse therapy (RR =0.130,95 % CI:0.031-0.541, P=0.005) and resolution of NPSLE (RR= 0.169, 95%CI:0.042-0.679,P=O.012)were protective factors. Conclusions Infection is the main cause of death in patients of LN complicated with NPSLE. Survival rate of LN patients with NPSLE in this study is lower than those of LN and NPSLE alone reported by other authors. Hypertension, pulmonary infection and acute renal failure are risk factors of mortality, while CTX impulse therapy and resolution of NPSLE reduce the mortality and improve the prognosis.
