The prevalence, causes and outcome of this condition vary among countries due to differences in environmental, socioeconomic, and health delivery systems. The common causes that have been reported in several studies are PIH, Haemorrhages and Sepsis while the outcomes may be either complete renal recovery, progression to CKD and hence dialysis dependency or death. This study aimed at determining clinical presentation and treatment outcomes of Pregnancy-Related Acute Kidney Injury in Pregnant women admitted at the Benjamin Mkapa Hospital, Dodoma, Tanzania. Results: Out of 4007 pregnant women who were admitted to the maternity ward 51 pregnant women were found to have PRAKI. Of those with PRAKI, 74.5% were between 21 to 25 years. The leading causes of PRAKI were PPH 12 (23.53%), Eclampsia 12 (23.53%), and pre-eclampsia 12 (23.5%). Hemodialysis therapy was provided to 22 (43.1%) patients, 15 (29.4%) individuals recovered spontaneously with medical management and 14 (27.5%) missed haemodialysis therapy due to various reasons. The mortality due to PRAKI was 17 (33.3%). Conclusion and Recommendation: Pre-eclampsia/eclampsia and post-partum haemorrhage were found to be the main causes of PRAKI. The mortality related to PRAKI is high and Hemodialysis therapy is vital help to prevent deaths for pregnant women with PRAKI. Pregnant women who develop acute kidney injury should be followed closely and a nephrologist should be consulted early. Early referral should be done by the lower level facilities for all at-risk pregnant women to a specialized multidisciplinary health facility.展开更多

Methods: The research workwas carried out in our hospital from January 2018 toJanuary 2019. In this study, 50 patients were selectedas related breast cancer patients and 50 non-pregnancyrelated breast cancer patients were selected as controlgroup. The clinical characteristics and prognosis ofthe two groups were compared and analyzed. Results:According to the incidence of pregnancy-related breastcancer, the onset of breast cancer is in pregnancy andlactation, with more than half of the total number ofpatients having two or more pregnancies and 74.0%of the patients having breast feeding history. In thetwo groups, most of the patients went to see a doctorbecause of palpable breast masses, and the averagemaximum diameter of tumors in PBC group was (5.13± 3.22)cm, including 5 cases accompanied by dimplesign, 7 cases accompanied by nipple depression, 8cases accompanied by inflammatory changes of skin,3 cases with pathological changes involving wholemilk, and 27 cases (54.00%) with palpable axillaryenlarged lymph nodes on the same side. The averagemaximum value of tumor in Non-PABC group was(3.94 ± 2.11) cm, with 5 cases accompanied by dimplesign, 4 cases accompanied by nipple depression, and 9cases (18.00%) with palpable axillary lymph nodes onthe same side. Conclusion: As far as pregnancy-relatedbreast cancer is concerned, the clinical misdiagnosisrate is relatively high and the prognosis is poor.Prenatal examination and breast-feeding breast cancerexamination are needed to ensure early detection anddiagnosis. This is the key factor to ensure the survivalrate of pregnancy-related breast cancer patients and haspositive significance for clinical development.展开更多

Methods: Collect the literature reports on the early diagnosis of respiratory tract infection in children by the combined detection of WBC, CRP and SAA in recent years, and follow up the relevant literature reports from the selection of “new three routine” laboratory items for rapid diagnosis in pediatric outpatient department and the application of the combined detection of WBC, CRP and SAA in the early diagnosis of respiratory tract infection in children. Results: Many literature studies found that the combined detection of WBC, CRP and SAA has important clinical significance in the early diagnosis of respiratory tract infection in children. Conclusion: Through reviewing the relevant literature, we can understand the application of WBC, CRP and SAA combined detection in the early diagnosis of respiratory tract infection in children. To provide more accurate and reliable laboratory data for the early diagnosis and treatment of respiratory tract infection in children in the future.展开更多

Methods: The serum 13-HCG (β-human chorionic gonadotropin) and PAPP-A levels of 25 normal pregnant women, 28 patients with complete hydatidiform mole and 38 patients with invasive mole were measured by enzyme linked immunosorbent assay (ELISA) during the periods of diagnosis, treatment and follow-up. Results: Compared with control group, patients with complete mole and invasive mole had higher levels of β-HCG (P 〈 0.01). But there was no significant difference between the complete and invasive mole group (P 〉 0.05). The PAPP-A level of complete mole group was significantly higher than that of control group (P 〈 0.01). The PAPP-A level of invasive mole group was significantly higher than that of complete mole group and control group(P 〈 0.05). In complete mole group, serum β-HCG and PAPP-A levels of the patients with malignant sequelae were significantly higher than those with benign sequelae (P 〈 0.05). The β-HCG level had no relationship with the clinical stage of invasive mole. However, the PAPP-A level increased with clinical advancement of invasive mole. The levels of β-HCG and PAPP-A gradually decreased after evacuation in patients with complete moles, but maintained positive or even increased in patients with subsequent malignancy diagnosis of hydatidiform mole and invasive mole, but Conclusion: The PAPP-A level can give us some help not only in early also in the prognosis of malignant sequelae.展开更多

Atherosclerotic arteries obtained at autopsy from patients who died suddenly of cardiac causes indicate that pregnancyassociated plasma protein-A ( PAPP-A ) was abundantly expressed in plaque cells and in the extracellular matrix of ruptured and eroded unstable plaques, but not in stable plaques. Here we examined circulating PAPP-A levels in patients with ACS in order to evaluate its potential use in identifying vulnerable patients.展开更多

In a previous study, we demonstrated that the expression of SP-A in the human renal tubular epithelial (HK-2) cells can be stimulated by lipopolysaccharide (LPS). The present study evaluated the possible signal-transducing mechanisms of LPS-induced SP-A biosynthesis in the HK-2 cells. Methods: Tetrazolium salt colorimetry (MTT) assay was used to detect cell viability of HK-2 cells after LPS stimulation on different time points. HK-2 cells were stimulated with 100 ng/ml of LPS for different durations to determine the effects of LPS on SP-A and toll-like receptor 4 (TLR4) messenger RNA (mRNA) expression, as well as phosphorylation of mitogen-activated/ extracellular signal-regulated kinase (MEK) 1, extracellular signal-regulated kinase 1/2 (ERK1/2), p38 mitogen-activated protein kinase (p38MAPK), and nuclear factor-kappa B (NF-KB) inhibitor-alpha (IkB-a). Then, HK-2 cells were pretreated with CLI-095, a TLR4 inhibitor, to analyze mRNA and protein levels of SP-A and TLR4 and expression of NF-KB ill the cytoplasm and nucleus of HK-2 before LPS exposure. Results: HK-2 cells exposed to 100 ng/ml of LPS for 1,6, and 24 h did not affect cell viability which showed no toxic effect of 100 ng/ml LPS on cells (P = 0.16); however, the biosynthesis of SP-A mRNA and protein in HK-2 cells was significantly increased (P = 0.02). As to the mechanism, LPS enhanced transmembrane receptor TLR4 protein expression. Sequentially, LPS time dependently augmented phosphorylation of MEKI, ERKI/2, and p38MAPK. In addition, levels of phospborylatedand nuclear NF-KB were augmented with LPS exposure for 2 h. LPS-induced SP-A and TLR4 mRNA as well as NF-KB expression were significantly inhibited by pretreatment with CLI-095. Conclusions: The present study exhibited that LPS can increase SP-A synthesis in human renal epithelial cells through sequentially activating the TLR4-related MEK1 -ERK 1/2-NF-kB-dependent pathway.展开更多
