ObjectiveTo determine the impact of lupus flares on maternal and fetal outcomes in pregnant patients with systemic lupus erythematosus(SLE).MethodsData was obtained from 46 pregnancies of 44 pregnant women with SLE.The relationship between lupus flares and pregnant outcomes,and the risk factors for adverse maternal and fetal prognosis were analyzed.T-test,X2 test or Fisher's exact test and Logistic regression were used for statistical analysis.Results① Lupus flares occurred in19(41％)pregnancies(group A) and stable lupus disease was observed in 27(59％) pregnancies(group B) during pregnancy.Compared to pregnancies in patients with stable lupus disease at the conception(n=32),pregnancies in patients with unstable lupus disease at the conception(n=8) had higher lupus flare during pregnancy( 100％ vs 16％,P＜0.05).(②) The common manifestations of lupus flares during pregnancy were lupus nephritis (LN) (11 cases),skin rashes (10 cases),arthritis (7 cases),and the common complication was infection ( 11 cases).(③) The incidence of premature labor,fetal growth retardation (FGR) and fetal loss in group A was 42％,47％ and 26％ respectively,which was significantly higher than that of the group B (7％,15％ and 0 respectively)(P＜0.05).There was no difference in the incidence of preeclampsia,fetal distress and neonatal asphyxia between the two groups ( 16％ vs 7％,16％ vs 19％,5％ vs O,respectively,P＞0.05).The incidence of premature labor and FGR in patients with active LN was higher than that of patients without active LN (55％ vs 11％,64％ vs 17％,respectively,P＜0.05).(④)The binary Logistic regression analysis showed that renal impairment,hypocomplementemia,aPL and serum urea nitrogen level were independent risk factors for premature delivery,FGR,fetal loss and fetal distress.Conclusion(①) Lupus flares during pregnancy increase the incidence of premature labor,FGR and fetal loss.Active LN during pregnancy can increase the incidence of premature labor and FGR.② Renal impairment,hypocomplementemia,aPL and serum urea nitrogen level are associated with adverse fetal outcomes in pregnant patients with SLE.

Objective To observe the effect of bacillus bifidus preparation on the prevention of gastrointestinal side effects in children with acute lymphocyte leukemia (ALL) during high-dose methotrexate (HD-MTX) chemotherapy.Methods One hundred and fifty-two ALL children were randomly assigned into 2 groups according to the suggestion of diagnosis and treatment of ALL in childhood.There were 76 patients in each group.In the treatment group,there were 46 male and 30 female,aged 2 to 13 years old (the median age was 8 years).While in the control group,there were 41 male and 35 female (the median age was 8.2 years).They were treated with the same chemotherapy schedule (HD-MTX),supportive therapies and infection preventive measures.ALL children in the treatment group were additionally given the bacillus bifidus preparation (one tablet for 2 to 6 years old,and two tablets for 7 to 15 years old,3 times daily),if their WBC was more than 2.0?109 L-1.Those in the control group were given vitamin B complex tablets (one tablet for 2 to 6 years old and two tablets for 7 to 15 years old,3 times daily).Results ALL children in treatment group had less diarrhea,abdominal pain,nausea and vomiting,or liver function impairment induced by chemotherapy than those in control group.However,the bacillus bifidus preparation had no significant effects on the symptoms of fever and oral mucosal erosions in the period of chemotherapy.Conclusion The bacillus bifidus preparation is clinically useful for the prevention of gastrointestinal side effects associated with HD-MTX chemotherapy.

OBJECTIVETo investigate the effect of urokinase on hepatic fibrogenesis in rats.

METHODSHepatic fibrosis was induced in rats by complex pathogenic factors including subcutaneous injections of carbon tetrachloride, alcohol and cholesterol feeding. Animals were randomly divided into 3 groups: normal control group, hepatic fibrosis group (complex pathogenic factors for 6 weeks), UK prevention group (complex pathogenic factors+UK for 6 weeks). The animals were sacrificed at the end of week 6. The expression of alpha-SMA, uPA, PAI-1, TGFb1, TIMP-1, collagen type I and type III proteins in hepatic fibrosis tissue was detected by immunohistochemistry, the expression of PAI-1 and TGFb1 mRNA in the hepatic fibrosis tissue was quantified by real time RT-PCR. The serum levels of hyaluronicacid (HA), alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin (TBil) and the content of liver hydroxyproline (Hyp) were detected using ELISA kits.

RESULTSThe serum ALT, AST, TBil, HA and the content of liver Hyp were (46.66+/-6.30) U/L, (126.26+/-31.65) U/L, (31.11+/-4.20) micromol/L, (109.70+/-18.81) microg/L and (0.98+/-0.09) mg/(g liver), respectively, in UK prevention group, which were significantly lower than those [(101.57+/-11.97) U/L, (205.89+/-56.26) U/L, (67.75+/-2.75) micromol/L, (184.43+/-32.36) microg/L and (1.65+/-0.16) mg/(g liver), respectively] in hepatic fibrosis group (q = 3.3801-20.0061, P < 0.01). The levels of a-SMA, collagen type I, type III, TIMP-1, PAI-1, TGFb1 proteins were (299.27+/-37.36), (210.05+/-27.17), (192.94+/-24.48), (213.70+/-32.21), (204.25+/-17.92), (205.97+/-23.81), respectively, in UK prevention group, which were significantly lower than those [(418.83+/-30.21), (323.77+/-21.53), (302.37+/-31.43), (376.63+/-25.19), (313.53+/-26.67) and (327.42+/-36.75), respectively] in hepatic fibrosis group. The level of uPA protein was increased, and the expression of PAI-1, TGFb1 mRNA in hepatic fibrosis tissue was decreased in UK prevention group.

CONCLUSIONIn the early stage of hepatic fibrogenesis, urokinase can attenuate the progression of rat hepatic fibrosis via upregulation of uPA, downregulation of TGFb1, and inhibition of HSC activation.

As an extension of proteomics, peptidomics has been widely used in medical and biological researches. However, the effect of reproducibility of identification method on peptidomics is not yet clear. In this work, the urine sample of a healthy people was analyzed for seven times in parallel by nano-liquid chromatography-high-resolution tandem mass spectrometry. To illustrate the variability and stability among these experiments, the number of spectra, the utilization of total spectra, the number of identified peptides, the number of proteins, and the ionic strength and retention time of peptides were counted and compared. The average number of peptides was 208 and the standard deviation was 38. 7. After all of data were combined, 426 peptides belonging to 114 proteins were obtained, while only 109 peptides coming from 35 proteins were identified in each experiment, indicating that there were both an randomness and a relative stability for LC-MS analysis. Increasing the number of parallel experiments would expand the data set of peptidomics, but the rate of increase would decrease over 3 or more measurements. Compared with peptides, the results of peptidomics were more stable at protein level, indicating that proteins were more robustly peptidomics biomarker than the peptides.

This study was aimed to investigate the expression of Hippo signaling pathway core element MST1 gene in acute leukemia (AL) patients, and explore its relation with AL pathogenesis and prognosis. 50 newly diagnosed patients with AL, 33 normal people, 23 patients with AL in complete remission, 12 refractory or relapsed patients were tested for the expression of MST1 gene by real-time quantitative PCR, Western blot was used to further validate the level of MST1 protein expression. And combined with clinical data, prognostic factors of the patients were analyzed. The results indicated that compared with the normal people, the expression level of MST1 in newly diagnosed patients with AL significantly decreased (P < 0.05), but significantly increased in AL patients with complete remission (CR), the difference of expression was statistically significant before CR and after CR (P < 0.05). Compared with refractory or relapsed patients, the expression level of MST1 gene in newly diagnosed patients was not significantly different (P > 0.05). Besides, the expression level of MST1 between the patients with CR and the normal people was not significantly different (P > 0.05). It is concluded that the low expression of MST1 may be related with the pathogenesis and prognosis of AL.

OBJECTIVETo explore the clinical and pathological features of liver injury in adults with acquired rubella.

METHODSThirty-six adult patients with acquired rubella (AAR) were enrolled in this study, the liver functions were dynamically analyzed, liver biopsy was done in two patients.

RESULTSLiver injury was found in 77.8% of the 36 patients, with slight elevation of ALT and/or AST. The highest incidence and the most serious liver injury occurred in the period of 6-10d after vanishing of the rashes. Viral inclusion bodies were found in the liver specimen, with complete histological architecture but slight inflammation. The mean hospitalization days of AAR accompanied with liver injury and without liver injury were 18.2 days, 7.8 days, respectively (u=3.596>1.96, P<0.05).

CONCLUSIONHigh incidence of liver injury is observed in the adult patients with acquired rubella occurred in recent years, usually exhibited by mild liver injury with slight elevation of ALT. The elevation of AST or jaundice may indicate more serious liver injury, and these patients should be given active treatment to prevent acute liver failure. Liver injury may prolong the course of rubella patients.
