Objective:To observe clinical significance between changes of OPN,IL-18 levels and relation ship with hepatic function in patients with chronic hepatic disease infected by HBV.Methods:The levels of OPN,IL-18 in peripheral blood of 102 patients with chronic hepatitis B,34 patients with hepatitis B-related cirrhosis,95 HBV carriers and 20 healthy people as the control group were respectively detected with ELISA.Results:The levels of OPN and IL-18 in chronic hepatitis B and hepatitis B-related cirrhosis groups were significantly increased compared with that of health control group(P

Objective To investigate the gene defects of a pedigree with inherited coagulation factor Ⅺ (FⅪ) deficiency by analyzing its phenotype and molecular genetic characteristics. Methods A pedigree with inherited FⅪ deficiency was enrolled in this study. The activated partial thromboplastin time (APTF), prothrombin time (PT), FⅪ activity (FⅪ: C) and FⅪ antigen (FⅪ: Ag) were determined for phenotype diagnosis. Fifteen exons and their flanks of F11 gene from the proband's genomic DNA were amplified by polymerase chain reaction (PCR), and the PCR products were directly sequenced to analyze the F11 gene mutation. The PCR products amplified from genomic DNA from the proband, her parents and 100 healthy donors were digested with restriction enzyme BssSI to exclude gene polymorphism and confirm the mutation site. The cleavage site in the signal peptide was predicted by the SignalP software. Results The values of APTT, PT, FⅪ: C and FⅪ: Ag of the proband were 69.5 s, 12.3 s, 2.6% and 2.5%, respectively, indicating that this case was cross-reacting material (CRM) negative. The same values of healthy controls were 35 s, 13 s, 100% and 100%, respectively. As compared with Genbank AY191837 sequence, four variants in F11 exons were found. G3733C heterozygous mutation in exon 2 causod Gly to Arg substitution at-1 amino acid position in signal peptide (G-1R). The G3733C mutation in exon 2 introduced a new BssSI enzyme digestion site. Further analysis of the 100 randomly collected DNA samples from the normal population excluded the possibility of G3733C as a polymorphism. CI6642T heterozygous mutation in exon 8 introduced a premature stop codon at 263 amino acid position (Q263Term). Conclusions G-1R mutation and Q263Term compound heterozygous mutation in F11 gene are the mechanism of FⅪ deficiency for the proband. G-1R mutation is a novel F11 gene mutation causing inherited FⅪ deficiency.

Objective: To observe relation among sICAM-1 level in the sera of patients with chronic viral hepatic disease, viral replication and the clinical significance. Methods: The level changes of sICAM-1, IL-1,IL-8 and TNFa in the sera of patients with chronic hepatitis B(CH),chronic severe hepatitis B(CSH) and hepatocirrhosis (HC) were detected by ELISA. Results: The levels of sICAM-1,IL-1,IL-8 and TNFa in sera of the patients with chronic viral hepatic disease were significantly higher than those of healthy control group(P<0.01). The bilirubin level in the sera of patients with chronic viral hepatic disease of different clinical types positively correlated with sICAM-1 and cytokine activities. The sICAM-1 level in the sera of HBV-DNA or HBeAg positive patients was significantly higher than those of negative patients(P<0.05,P<0.01). Conclusion: The sICAM-1 level and activities of cytokine IL-1,IL-8 and TNFa as well as the bilirubin level in the sera of the patients can reflect the necrosis degree of hepatocytes, and the sICAM-1 level and activities of IL-1,IL-8 and TNFa were related to state of HBV carrier or the active degree of HBV in patients with hepatic disease.

Objective To investigate the effects of different umbilical cord ligation methods on anemia and jaundice in preterm infants with a gestational age less than 32 weeks.Methods A total of 135 preterm infants with a gestational age less than 32 weeks were recruited and randomly divided into the umbilical cord milking group,the delayed cord clamping group and the immediate cord clamping group,with 45 cases in each group.Comparisons among three groups were performed on hemoglobin,hematocrit at 1 h and 1 week after birth,and bilirubin peak,total time of phototherapy,the incidence of anemia,pathologic jaundice as well as polycythemia before discharge.Results Finally 40 cases in the umbilical cord milking group,42 cases in the delayed cord clamping group and 38 cases in the immediate cord clamping group were recruited.Compared with the immediate cord clamping group,Hb(g/L)and hematocrit(％) levels were significantly higher in the umbilical cord milking group and the delayed cord clamping group(P＜0.05),the anemia rate was significantly lower in umbilical cord milking group and the delayed cord clamping group(P＜0.05).However,there were no statistical differences in Hb(g/L) and hematocrit(％) levels as well as ane mia rate between the umbilical cord milking group and the delayed cord clamping group (P＞0.05).There were no significant differences among three groups in bilirubin peak,total time of phototherapy and the incidence of pathologic jaundice as well as polycythemia.Conclusion Umbilical cord milking and delayed cord clamping can both reduce the anemia rate,but not increase the risk of pathological jaundice.Umbilical cord milking can be preferred method for preterm infants with a gestational age less than 32 weeks and asphyxia.

Objective:To explore the application effects of a new self-designed device for measuring postpartum blood loss in women with postpartum hemorrhage after vaginal delivery, so as to provide a basis for early identification and treatment of postpartum hemorrhage.Methods:The research was a quasi-experiment study. A total of 12 824 women who delivered vaginally in Women's Hospital of Nanjing Medical University from July 2021 to June 2022 were conveniently selected. Among them, the pregnant women enrolled from January to June 2022 were selected as the experimental group, and the pregnant women enrolled from July to December 2021 were included in the control group, with 6 412 cases in each group. The self-designed new postpartum blood loss measuring device was used to evaluate the blood loss in the experimental group, while the traditional blood collecting basin was taken in the control group.The differences between the two groups in the assessment error of 24 hours postpartum blood loss, postpartum blood loss at 2 hours and 24 hours, postpartum hemorrhage rate, severe postpartum hemorrhage rate and midwives′ satisfaction with the assessment of blood loss were compared.Results:The assessment error of 24 hours postpartum blood loss in the experimental group was 180.00 (80.00, 300.00) ml, which was lower than 192.00 (80.00, 310.00) ml in the control group, and the difference was statistically significant ( Z = - 2.04, P<0.05). The postpartum blood loss at 2 hours and 24 hours in the experimental group was 312.00 (290.00, 330.00) ml and 415.00 (385.00, 440.00) ml, respectively, which was higher than 310.00 (280.00, 330.00) ml and 407.00 (380.00, 435.00) ml in the control group, and the differences were statistically significant ( Z = - 9.86, - 5.42, both P<0.001). The rates of postpartum hemorrhage and severe postpartum hemorrhage in the experimental group were 6.50% (417/6 412) and 2.21% (142/6 412), respectively, higher than 4.71% (302/6 412) and 1.59% (102/6 412) in the control group, and the differences were statistically significant ( χ2 = 19.49, 6.69, both P<0.05). Midwives′ satisfaction score with the assessment of blood loss in the experimental group was (18.17 ± 1.02) points, higher than that in the control group (17.78 ± 1.17) points, and the difference was statistically significant ( t = 2.33, P<0.05). Conclusions:The use of a new device for measuring postpartum bleeding during vaginal delivery can reduce errors in evaluating postpartum blood loss within 24 hours, improve the detection rate of postpartum hemorrhage and severe postpartum hemorrhage, and midwives are satisfied with it.
