Objective To evaluate the clinical value of fasting blood glucose (FBG) in the diagnosis of multiple organ dysfunction syndrome (MODS) caused by pulmonary infection in elderly patients with diabetes. Methods Patients over 65 years old with diabetic pulmonary infection admitted to Department of Cadres Ward of Bethune International Peace Hospital of PLA from July 2015 to December 2016 were enrolled. According to the patient's highest FBG level during pulmonary infection, all patients were divided in two groups. The cases whose FBG ≥8.83 mmol/L were served as suspicious multiple organ dysfunction syndrome in the elderly (MODSE) group, and those had FBG < 8.83 mmol/L were served as suspicious non-MODSE group. The incidence of MODSE in suspicious MODSE group and suspicious non-MODSE group was compared. The receiver operating characteristic curve (ROC) was drawn, and the clinical value of highest FBG in the diagnosis of MODSE caused by pulmonary infection in elderly patients with diabetes was assessed. Results 119 elderly patients with diabetes and pulmonary infection were enrolled in the analysis. All patients were male, with age of 76-105 years with an average of (89.41±4.16) years. Among 119 patients, 55 of them with suspected MODSE, 64 of them with suspected non-MODSE. The incidence of MODSE in suspicious MODSE group was significantly higher than that in suspicious non-MODSE group (78.2% vs. 12.5%), with statistically significant difference (χ2 = 52.108, P = 0.000). The area under the ROC curve of the highest FBG for diagnosis of MODSE was 0.895, and 95% confidence interval (95%CI) was 0.839-0.951 (P < 0.001). When using FBG ≥ 8.83 mmol/L to diagnose MODSE induced by pulmonary infection in elderly patients with diabetes, the sensitivity was 84.3% and the specificity was 82.4%. Conclusion FBG ≥ 8.83 mmol/L, as an indicator reflecting the changes of metabolic function, have a diagnostic value for MODSE caused by pulmonary infection in elderly patients with diabetes.

Objective The study aimed to analyze the clinical data of patients with pulmonary embolism and summarize the clinical characteristics of pulmonary embolism,in order to improve the correct diagnostic rate and the prognosis. Methods Data of 178 patients who were cured in our hospital from January 2011 to December 2014 were analyzed retrospectively,including relative risk factors,clinical behaviors,examination data,misdiagnosis and prognosis. Results Patients with pulmonary embolism had related basic diseases and risk factors. Their clinical symptoms,signs and ordinary detection methods indicated pneumatorexis and cardiovascular injury,but lacked of specificity. The misdiagnosis rate of the first diagnosis was 48.88%,including 22 cases of the misdiagnosis to COPD, 18 cases to pneumonia and 16 cases to coronary heart disease. The misdiagnosis rate of elderly patients was 56.36%, while that of the young and middle-aged patients was 36.80%,the difference was statistically significant,P < 0.05. Computed tomography pulmonary angiography(CTPA)could accurately observe the pathological changes of pulmonary embolism,and all the patients were diagnosed by CTPA in the research. 11 cases(10%)of elderly patients died,while 2 cases(2.9%)happened in young and middle-aged patients. There was no statistical significant difference(P > 0.05). Conclusion Although the related risk factors of pulmonary embolism in patients existed,the misdiagnosed rate of the disease was high and prognosis was poor due to many confusing basic diseases. And the symptoms,signs and ordinary inspection of the patients lacked specificity. CTPA,being utilized to diagnose pulmonary embolism reliably,should be promoted.

OBJECTIVETo assess the level of alpha-fetoprotein (AFP) messenger RNA (mRNA) in peripheral blood of nude mice, and to study its relationship with tumor recurrence and metastasis after curative resection of hepatocellular carcinoma (HCC).
METHODSThe metastatic model of human HCC in nude mice LCI-D20 was used in this study. Curative resection was performed at 10th day after tumor implantation in 28 nude mice. Interferon alpha-1b (IFN alpha-1b) was administered subcutaneously from the next day after resection, at doses of 3 10(7)U/kg/d (8 nude mice), 1.5 10(7) U/kg/d (8 nude mice) respectively in the treatment groups, and normal saline alone in the controlled group (12 nude mice). Thirty-five days after treatment, one milliliter of peripheral blood was taken and AFP mRNA was quantitatively analyzed using TaqMan real-time quantitative RT-PCR. The mice were sacrificed. The size of recurrent tumor was measured and the presence of lung metastases was observed.
RESULTSThe liver recurrent rate, lung metastatic rate and positivity of AFP mRNA in the controlled group were all 100% (12/12), whereas it was 62.5% (5/8), 0% (0/8), 87.5% (7/8) respectively in the IFN alpha-1b 1.5 10(7)U/kg/d treated group. The recurrent tumor in liver of the IFN alpha-1b 1.5 10(7)U/kg/d treated group was much smaller than that of the controlled group (25 mm(3) 2 mm(3) vs 1143 mm(3) 3 mm(3), t =9.27, P<0.01), and the level of AFP mRNA was also lower than that of the controlled group [(85 6)copies/mug vs (955 2) copies/mug, t =4.33, P<0.01]. In the IFN alpha-1b 3 10(7)U/kg/d treated group, there was only one recurrent tumor (0.5 mm(3)), no lung metastasis, and the positivity of AFP mRNA was 0% (?(2)=11.67, P<0.01).
CONCLUSIONSThese results suggest that the level of AFP mRNA in peripheral blood may indicate recurrence and/or metastasis after curative resection of HCC. TaqMan real time quantitative RT-PCR is a very sensitive and convenient method for detecting circulating cancer cells.

Objective To investigate the correlation between serum hepcidin level and iron, mineral metabolism in maintenance hemodialysis (MHD) patients. Methods Seventy-five MHD patients were selected. The serum hepcidin, serum iron and mineral metabolism indexes were detected by enzyme-linked immunosorbent double antibody sandwich method, and their correlation was analyzed. Results The level of serum hepcidin in 75 MHD patients was 87- 264 μg/L. The patients were divided into 3 groups according to serum hepcidin level. In group A, the serum hepcidin level of 26 cases was<120 μg/L; in group B, the serum hepcidin level of 24 cases was 120- 200 μg/L; in group C, the serum hepcidin level of 25 cases was>200 μg/L. There were no significant differences in age, gender, albumin and serum calcium among 3 groups (P > 0.05). The levels of ferritin, transferrin saturation (TS), serum phosphorus and parathyroid hormone (PTH) increased in the 3 groups as the hepcidin level increased, while hemoglobin, serum iron, total iron binding capacity (TIBC), and 25 hydroxy vitamin D decreased significantly, and there were statistical differences (P<0.05). The Pearson correlation analysis result showed that serum hepcidin was positively correlated with ferritin, PTH, serum phosphorus (r = 0.862, 0.536 and 0.320; P<0.01); and serum hepcidin was negative correlation with serum iron, TIBC, hemoglobin, 25 hydroxy vitamin D (r=-0.358,-0.270,-0.284 and-0.614; P<0.01); but there was no correlation between serum hepcidin and albumin and serum calcium (r=0.018 and-0.005, P>0.05). Conclusions The serum hepcidin level in MHD patients is closely related to iron and mineral metabolism.

Objective To explore the effects of both folic acid,p16 protein expression and their interaction on progression of cervical cancerization.Methods Participants were pathologically diagnosed new cases,including 80 women with normal cervical (NC),55 patients with low-grade cervical intraepithelial neoplasia (CIN Ⅰ),55 patients with high-grade cervical intraepithelial neoplasia (CIN Ⅱ/Ⅲ) and 64 patients with cervical squamous cell carcinoma (SCC).Serum folate levels were detected by microbiological assay method while p16 protein expression levels were measured by Western-blot.In vitro,cervical cancer cell lines C33A (HPV negative) and Caski (HPV16 positive) were treated with different concentrations of folate.Proliferation and apoptosis of cells and the levels of p16 protein expression were measured in groups with different folic acid concentrations.Results Results showed that the levels of serum folate were (5.96± 3.93) ng/ml,(5.08±3.43) ng/ml,(3.92 ± 2.59) ng/ml and (3.18 ± 2.71) ng/ml,and the levels ofpl6 protein were 0.80 ± 0.32,1.33 ± 0.52,1.91 ± 0.77,and 2.09 ± 0.72 in the group of NC,CIN Ⅰ,CIN Ⅱ/Ⅲ and SCC,respectively.However,the levels of serum folate decreased (trend X2 =32.71,P< 0.001) and p 16 protein expression increased (trend x2=56.06,P<0.001) gradually along with the severity of cervix lesions.An additive interaction was seen between serum folate deficiency and high expression of p l 6 protein in the CIN Ⅰ,CIN n/Ⅲ and SCC group.Results in vitro showed that,with the increase of folate concentration,the inhibition rate of cell proliferation (C33A:r=0.928,P=0.003;Caski:r=0.962,P=0.001) and the rate on cell apoptosis (C33A:r=0.984,P<0.001;Caski:r=0.986,P<0.001) all increased but the levels of p16 protein expression (C33A:r=-0.817,P=0.025;Caski:r=-0.871,P=0.011) reduced.The proliferation inhibition rate (C33A:r=-0.935,P=0.002;Caski:r=-0.963,P=0.001) and apoptosis rate of cells (C33A:r=-0.844,P=0.017;Caski:r=-0.898,P=0.006) were negatively correlated with the levels of p16 protein expression.Conclusions Our findings indicated that both serum folate deficiency and high expression of p16 protein could increase the risk of cervical cancer and cervix precancerous lesion,and there was an additive interaction between them.Our findings suggested that folic acid supplementation could reverse the abnormal expression of p16 protein,and effectively promote apoptosis and inhibit proliferation in cervical carcinoma cells.

Objective To evaluate the relationship between different levels of central venous pres-sure (CVP) and blood loss during pediatric living donor liver transplantation (LDLT). Methods Pediat-ric patients underwent LDLT in Renji Hospital from 2006 to August 10, 2016 were retrospectively reviewed. The patients were divided into 2 groups according to the different CVP levels before peritoneum closure:central venous pressure<10 mmHg group ( group L) and CVP≥10 mmHg group ( group H) . The primary outcome measure was intraoperative blood loss. The secondary outcome measures were duration of mechani-cal ventilation in intensive care unit (ICU), duration of ICU stay, length of postoperative hospital stay, intraoperative blood loss, intraoperative blood transfusion, intraoperative volume of liquid infused, opera-tion time and anesthesia time. Results A total of 442 pediatric patients were enrolled in this study, with 209 cases in group L and 233 cases in group H. Compared with group H, the intraoperative blood loss was significantly decreased, the anesthesia time, operation time and length of postoperative hospital stay were shortened ( P<0. 05) , and no significant change was found in intraoperative blood transfusion, intraopera-tive volume of liquid infused, duration of mechanical ventilation in ICU or duration of ICU stay in group L ( P>0. 05) . Conclusion Maintaining intraoperative CVP<10 mmHg can markedly reduce the blood loss during LDLT and is helpful for postoperative recovery in pediatric patients.
