Objective To investigate the correlation between 24 h urinary protein quantitation and pregnancy outcome in patients with pre-eclampsia.Methods A total of 332 pre-eclampsia patients were selected in Tongji Hospital from January 2014 to December 2016.The patients were divided into microalbuminuria group(24 h urinary protein quantification ＜ 0.3 g,n =46),mild proteinuria group (0.3 g ≤ 24 h urinary protein quantification ＜ 2.0 g,n =98),moderate proteinuria group (2.0 g ≤ 24 h urinary protein quantification ＜ 5.0 g,n =71) and severe proteinuria group(24 h urinary protein quantification ≥ 5.0 g,n =117) according to the results of 24 h urinary protein quantification.The pregnancy outcomes were compared between the four groups.Results The 24 h urinary protein quantification and the serum creatinine,urea nitrogen,uric acid levels in the mild proteinuria group,moderate proteinuria group and severe proteinuria group were significantly higher than those in the microalbuminuria group (P ＜ 0.05);and gestational week was significantly shorter than that in the microalbuminuria group (P ＜ 0.05).The 24 h urinary protein quantification and serum urea nitrogen,uric acid levels in the moderate proteinuria group were significantly higher than those in the mild proteinuria group (P ＜ 0.05);and gestational week was significantly shorter than that in the mild proteinuria group (P ＜ 0.05);but there was no significant difference in serum creatinine level between the two groups (P ＞ 0.05).The 24 h urinary protein quantification,serum creatinine,urea nitrogen and uric acid levels in the severe proteinuria group were significantly higher than those in the mild proteinuria group (P ＜ 0.05);and the gestational week was significantly lower than that in the mild albuminuria group (P ＜ 0.05).The 24 h urinary protein quantification in the severe proteinuria group was significantly higher than that in the moderate proteinuria group (P ＜ 0.05),but there was no significant difference in the gestational week and serum creatinine,urea nitrogen,uric acid levels between the two groups (P ＞0.05).There was no significant difference in the rates of cesarean section and spontaneous labor between the four groups (P ＞0.05).The rate of induced labor in the moderate proteinuria group and the severe proteinuria group was significantly higher than that in the mild albuminuria group and the microalbuminuria group (P ＜ 0.05).There was no significant difference in the rate of induced labor between the mild proteinuria group and the microalbuminuria group (P ＞ 0.05).There was no significant difference in the rate of induced labor between the severe proteinuria group and the moderate proteinuria group (P ＞ 0.05).The incidence of complications in microalbuminuria group,mild proteinuria group,moderate proteinuria group and severe proteinuria group was 30.43％ (14/46),47.96％ (47/98),74.65％ (53/71) and 74.36％ (87/117) respectively;the incidence of complications in the moderate proteinuria group and the severe proteinuria group was significantly higher than that in the microalbuminuria group and the mild albuminuria group (P ＜ 0.05),but there was no significant difference in the incidence of complications between microalbuminuria group and mild albuminuria group (P ＞ 0.05),there was no significant difference in the incidence of complications between the moderate proteinuria group and the severe proteinuria group (P ＞0.05).The incidences of premature birth and neonatal asphyxia in the mild proteinuria group were significantly higher than that in the microalbuminuria group (P ＜ 0.05),and the body mass of the neonates was significantly lower than that in the microalbuminuria group (P ＜0.05),but there was no significant difference in the perinatal mortality rate and the incidences of fetal growth restriction(FGR) and poor neonatal resuscitation between the two groups (P ＞ 0.05).The incidences of FGR,premature birth,neonatal asphyxia,poor neonatal resuscitation and the perinatal mortality in the moderate proteinuria group and severe proteinuria group were significantly higher than those in the microalbuminuria group (P ＜ 0.05);and neonatal body mass was significantly lower than that in the mieroalbuminuria group (P ＜ 0.05).The incidences of FGR,premature birth and poor neonatal resuscitation and perinatal mortality in the moderate proteinuria group were significantly higher than those in the mild proteinuria group (P ＜ 0.05);and the neonatal body mass was significantly lower than that in the mild proteinuria group (P ＜ 0.05);but there was no significant difference in the neonatal asphyxia incidence between the two groups (P ＞ 0.05).The incidences of FGR,premature birth,neonatal asphyxia,poor neonatal resuscitation and perinatal mortality in the severe proteinuria group were significantly higher than those in the mild proteinuria group (P ＜ 0.05);and the body mass of the newborns was significantly lower than that in the mild albuminuria group (P ＜ 0.05).The incidence of neonatal asphyxia in the severe proteinuria group was significantly higher than that in the moderate proteinuria group (P ＜ 0.05),but there was no significant difference in the incidences of FGR,premature birth,poor neonatal resuscitation,perinatal mortality and neonatal body mass between the two groups (P ＞ 0.05).Conclusions The of 24 h urinary protein quantitation is closely related to the pregnancy outcome in patients with pre-eclampsia,the 24 h urinary protein quantification should be regularly detected in the patients with pre-eclampsia.When the urinary protein quantitation is more than 2.0 g,the incidences of maternal complications and poor prognosis of the perinatal infants is significantly higher,but the boundary value of the 24 h urinary protein quantitation for the diagnosis of severe pre-eclampsia still needs further large sample study.

Objective To explore the changes of proteomic spectra from plasma of patients with lung cancer or benign lung diseases and health controls in order to establish a primary diagnosis model of lung cancer. Methods The proteomic spectra from plasma of 108 patients with lung cancer, 40 patients with benign lung diseases and 22 healthy individuals were analysed by surface-enhanced laser desorption/ionization time of flight mass spectrometry ( SELDI-TOF-MS). The best decision tree model was established by cluster analysis and principal component analysis. Then the model was blindly validated by the protein of 21 patients with lung benign diseases and 47 patients with stage I lung cancer. Results Twenty-three significantly differentially expressed protein peaks were successfully detected (P <0.001). Blinded validation suggested that the accuracy for diagnosing lung cancer was 72. 06%, the sensitivity and specificity were 72. 34% and 71.43%, respectively, and the positive predictive value and negative predictive value were 85. 0% and 78. 95%, respectively. Conclusion SELDI-TOF-MS protein chip technology provides a new tool for the early diagnosis of lung cancer.

Objective To explore the relationship between the clinical features,serological markers and European League Against Rheumatism SS Disease Activity Index (ESSDAI) scores of primary Sj(o)gren's syndrome (SS).Methods We enrolled 106 patients,who fulfilled the 2002 classification criteria for primary SS from December 2008 to January 2015,to evaluate the relationship among the clinical characteristics,laboratory features,serological variables and ESSDAI scores.According to serological variables,the prognosis was subdivided into three distinct groups:favourable (no serological markers),intermediate (one serological marker) and poor (two or more serological markers).These data were analyzed by Chi-square test and variance analysis.Results The mean ESSDAI score of 106 pSS patients was (11±7).ESSDAI score was categorized according to the EULAR-SS recommendations as low activity,moderate activity and high activity (scores of 0-4,5-13 and ≥14,respectively),and the positive rate of antinuclear antibody (ANA) 1:100 (6 cases,37.5％;37 cases,66.1％;32 cases,94.1％) in three different ESSDAI levels was statistically different (x2＝18.110,P＜0.01).Those with positive ANA 1:100[positive (13±7) and negative (7±4)],anti-SSA antibody postive (12±7) and negative (9±7),anti-RNP antibody (positive 16±9 and negative 10±6) had higher ESSDAI scores than those with negative ones (F=8.812,P=0.0001;F=3.862,P=0.024;F=5.786,P=0.004).No statistical difference in ESSDAI means were found between patients with positive anti-SSB antibody,rheumatoid factor (RF),FS level,dry mouth,Raynoud's phenomenon and psychosomatic diseases.The ESSDAI scores of favourable group,intermediate group and poor group were significantly different (8±5,10±7,14±7,F=8.715,P=0.000 1).In comparison with the other two groups,the poor pSS patients had a higher frequency of positive ANA 1:100 (15 cases,55.6％;20 cases,57.1％;40 cases,90.9％),anti-SSA antibody(11 cases,0.7％;23 cases,41.1％;36 cases,81.8％),anti-SSB antibody (6 cases,2 2.2％;13 cases,37.1％;23 cases,52.3％),anti-RNP antibody (0 case,0;2 cases,5.7％;9 cases,20.5％) (x2=17.408,P=0.002;x2=14.306,P=0.006;x2=12.330,P=0.015;x2=1 1.482,P=0.022).Conclusion Patients with two or more serological markers may have higher ESSDAI score,and which in turn may associate with poor prognosis.
