We present an unusual case of an unstable pelvic fracture during pregnancy period, who suffered fetal death and splenic rupture simultaneously which developed massive delayed hemorrhage in abdomen. When considering potential causes of fetal death, direct trauma to the uterus, placenta, or fetus was not associated with a higher fetal mortality rate, compared with maternal hemorrhage. A cesarean section and splenectomy could rescue the maternal life from the hemorrhage situation. Successful treatment of these rare cases is possible with careful pre-, peri-, and post-operative evaluation of the mother and fetus by a multidisciplinary team.

AIMTo study the endogenous mechanism for the inhibition of aquaporin-1 expression in rat renal proximal tubule epithelial cells in response to acetazolamide.

METHODSPrimary cultured rat renal proximal tubule epithelia cells were divided into two groups: one was subjected to 1 x 10(-5) mol.L-1 acetazolamide, the other served as normal control. When grown to sub-confluency, the cells were disintegrated to perform isoelectrofocusing electrophoresis in order to find the differential proteins induced by the acetazolamide treatment. The differential proteins were defined by peptide mass fingerprinting technology.

RESULTSTwo differential proteins were found in the cell disintegrant. The pI 3.8 protein was reduced after treatment, which showed 21.4% similarity with the brush border membrane myosin from rat brain and testis, and 27% with glycogen phosphorylase; The pI 5.5 protein was increased on the contrary, with 20% similarity to phosphatidylinositol transfer protein alpha isoform.

CONCLUSIONAcetazolamide inhibited AQP1 expression probably by affecting the expression of pI 3.8 and pI 5.5 proteins.

Purpose: Nowadays most children with congenital heart disease (CHD) are expected to survive to adulthood. The healthcare focus needs to pay close attention to the important developmental tasks during their growth process. The women with CHD face some challenges in their critically developmental stages during pregnancy, delivery, and even motherhood. The lived experience of being a mother needs to be further concerned. This study aimed to explore the lived experience of first-time mothers with CHD. Methods: Descriptive phenomenological design was adopted. Semi-structured interviews were conducted from April to August 2018 with 11 primiparous women with CHD, who were recruited from the pediatric and adult cardiology outpatient departments at a medical center and who had a child aged between 6 months and 3 years. Giorgi's phenomenological analysis method was employed. Results: Six main themes arose from the analysis: (1) recognizing pregnancy risks, (2) performing self-care for health, (3) building self-worth from my baby, (4) adapting to postpartum life and adjusting priorities, (5) enjoying being a first-time mother, and (6) the factors contributing to success in high-risk childbirth. Conclusions The experiences that occurred prior to and after labor that were identified in this study can assist women with CHD to more capably prepare for and understand the process of becoming a mother, including recognition of the importance of a prepregnancy evaluation. The findings of this study can help women with CHD to better understand the path to becoming a mother and prepare themselves for the challenges that lie ahead.

This study was purposed to explore the expression of glucosylceramide synthase (GCS) in human leukemia cells and its relationship with multidrug resistance. RT-PCR was used to analyze peripheral blood samples from 53 leukemia patients with multidrug resistance/non-resistance, and to detect the expression level of GCS gene in HL-60 cells and HL-60/ADR cells, the expression level was compared with the level of mdr-1. The expressions of GCS protein and P-gp protein in HL-60 cells and HL-60/ADR cells were assayed by Western blot analysis. The results showed that the relative optical density ratio of GCS gene amplified bands in samples of leukemia patients with drug-resistance was significantly higher than that in samples of leukemia patients with drug non-resistance group (P < 0.05), meanwhile the significant enhancement of optical density value of GCS gene amplified bands accompanied by high expression of mdr-1 gene. Their correlation showed positive (P < 0.01, r = 0.6). The GCS mRNA and protein were overexpressed in HL-60/ADR cells, and their expression levels were obviously higher than that in HL-60 cells, meanwhile the expression of mdr-1 mRNA and P-gp also significantly increased in HL-60/ADR cells. It is concluded that the high level of GCS in leukemia patients possibly is associated with multidrug resistance of leukemia cells.

The effect of lanthanum carbonate on abdominal aortic calcification (AAC) in the elderly maintenance hemodialysis (MHD) patients was investigated. Fifty-four cases subjected to routine MHD complicated with skin pruritus admitted to our hospital were selected and randomly divided into case group (n=28) and control group (n=26). The control group was given routine MHD alone. The case group was given lanthanum carbonate additionally on the basis of routine MHD. The changes of itching degrees at first and third month, and serum calcium, phosphorus, calcium-phosphorus products, intact parathyroid hormone (iPTH) levels and AAC scores at third month after treatments were compared between the two groups. The correlation between calcium-phosphorus products and AAC scores was also analyzed. There was no significant difference in the baseline of blood urea nitrogen (BUN), serum creatinine (Scr), uric acid, albumin, hemoglobin, C reactive protein (CRP), low density lipoprotein (LDL), high density lipoprotein (HDL), triglyceride, total cholesterol between case group and control group (P>0.05 for all). There was also no significant difference in the baseline itching scores between the case group and the control group (P>0.05). At 1st and 3rd month after treatment, the itching scores in the case group were 14.2 ± 3.2 and 10.5 ± 2.3, respectively, which were significantly lower than the baseline and those in the control group (P<0.05 for all). At 1st and 3rd month after treatment, the itching scores in the control group were 23.6 ± 5.9 and 24.8 ± 6.3, respectively, which were significantly higher than the baseline (P<0.05). There was no significant difference in the baseline of serum calcium, phosphorus, calcium-phosphorus products, iPTH levels between the case group and control group (P>0.05). At 3rd month after treatment, serum phosphorus, calcium-phosphorus products and iPTH levels in the case group were decreased significantly as compared with the baseline (P<0.05), and the serum calcium, phosphorus, calcium-phosphorus products, and iPTH levels were statistically decreased as compared with those in the control group (P<0.05). The AAC scores showed statistically significant difference between the case group and the control group (P<0.05). The serum phosphorus and AAC scores showed a positive correlation in both two groups. It was suggested that the administration of lanthanum carbonate in the elderly MHD patients can effectively relieve itching, and simultaneously reduce serum phosphorus and iPTH levels, resulting in the attenuation of vascular calcification.

Objective To analyze the change of urinary iodine in a cohort of intervention trial and to observe the role of different doses on salt iodization and related impact factors on nutritional condition of iodine. Methods Multistage cluster sampling was used to sample three townships in two counties for community intervention with different doses (15 ± 5, 25 ± 5, 35 ± 5)mg/kg. Results Compared to the (35 ± 5)mg/kg group, the urine iodine levels of three experimental townships were gradually declining in county B when time went on, and the (15 ± 5) mg/kg group showed anobvious results, at 6,12,18 and 24 months, with the urine iodine level as 180.00,186.10,150.04,191.28 &mu;g/L respectively, which were in accordance with the WHO standard and reached to appropriate range (187.96&mu;g/L) at the 18 month. The townships at county Y under intervention had declined slightly, but the urine iodine levels did not reach the WHO standard. The thyroid volume declined from 3.65 ml to 3.40 ml in two counties and the difference between them was statistically significant. Conclusion To some extent, reducing the iodine concentration in salt, had a role of lowering the urine iodine level and reducing the strumous rate.

OBJECTIVETo evaluate the value of GeneSearch(TM) BLN assay as an intraoperative diagnostic method of sentinel lymph node metastases in breast cancer patients.

METHODSNinety consecutive patients were involved in this study. SLNs were intraoperatively identified and dissected, and then sectioned vertically to the long axis into multiple blocks. The odd blocks were tested by BLN assay and even ones prepared for frozen sectioning (FS), while all blocks were evaluated by touch imprint cytology (TIC). Post-operatively, residual tissues of the even blocks were assessed by histopathologic examination (4 - 6 µm thick serial sectioning permanent H&E slides were performed every 150 µm and one block made 6 slides).

RESULTSBLN assay could be performed within less than 35 min after learning curve of 10 cases. A correlation was found between cycle time values of mammaglobin or cytokeratin-19 and size of metastases, with Spearman correlation coefficients of 0.67 and 0.71, respectively. The accuracy, sensitivity, specificity, positive predict value (PPV) and negative predict value (NPV) of the assay were 95.6%, 93.3%, 96.7%, 93.3% and 96.7%, While FS had the sensitivity, specificity, PPV, NPV of 76.7%, 100%, 100%, 89.6%, and TIC of 73.3%, 100%, 100%, 88.2%, respectively. The sensitivity of the assay was higher than that of FS (P = 0.07), and was significantly higher than that of FS (P = 0.04). When assessing patients with micro-metastases, the assay had a sensitivity of 85.7%, which was significantly higher than that of FS and TIC (P = 0.03).

CONCLUSIONGeneSearch(TM) BLN Assay can replace FS and TIC for the intraoperative assessment of SLN.

Objective: Individuals with dementia are at a substantially elevated risk for mortality; however, few studies have examined multimorbidity patterns and determined the inter-relationship between these comorbidities in predicting mortality risk. Methods: This is a prospective cohort study. Data from 6,556 patients who were diagnosed with dementia between 1997 and 2012 using the Taiwan National Health Insurance Research Database were analyzed. Latent class analysis was performed using 16 common chronic conditions to identify mortality risk among potentially different latent classes. Logistic regression was performed to determine the adjusted association of the determined latent classes with the 5-year mortality rate. Results: With adjustment for age, a three-class model was identified, with 42.7% of participants classified as “low comorbidity class (cluster 1)”, 44.2% as “cardiometabolic multimorbidity class (cluster 2)”, and 13.1% as “FRINGED class (cluster 3, characterized by FRacture, Infection, NasoGastric feeding, and bleEDing over upper gastrointestinal tract).” The incidence of 5-year mortality was 17.6% in cluster 1, 26.7% in cluster 2, and 59.6% in cluster 3. Compared with cluster 1, the odds ratio for mortality was 9.828 (95% confidence interval [CI]=6.708–14.401; p<0.001) in cluster 2 and 1.582 (95% CI=1.281–1.953; p<0.001) in cluster 3. Conclusion Among patients with dementia, the risk for 5-year mortality was highest in the subpopulation characterized by fracture, urinary and pulmonary infection, upper gastrointestinal bleeding, and nasogastric intubation, rather than cancer or cardiometabolic comorbidities. These findings may improve decision-making and advance care planning for patients with dementia.

OBJECTIVETo explore the relationship between the overexpression of PKA RIalpha mRNA and cliniopathological parameters in lung cancer.

METHODSRT-PCR was used to detect the expression of PKA RIalpha mRNA in 54 cases with human lung cancer and matched normal tissues.

RESULTS(1) The expression of PKA RIalpha mRNA was significantly higher in cancer tissue (66.7%) than in normal tissues (20.4%) (P < 0.01). (2) The expression was significantly correlated with TNM stage (P < 0.01), being increased with TNM stage. (3) The expression was significantly higher in patients with positive lymph nodes than in those with negative lymph nodes (P < 0.01). (4) There were no significant associations of PKA RIalpha mRNA expression with histological type, differentiation grade or size of the tumor.

CONCLUSIONThis study indicates that the overexpression of PKA RIalpha mRNA may play an important role in the progression, metastasis and prognosis of lung cancer.
