Objective To observe the protection of aprotinin, ulinastatin and aminomethylbenzoic acid, aminomethylbenzoie acid on blood fibrinolytie system during cardiopulmonary bypass(CPB). Methods Thirty-six patients with rheumatic heart disease who were treated by valve replacement were randomly divided into three groups: aprotinin group (group A, 12 cases): aprotinin 2000 kU was added into the priming solution; ulinastatin and aminomethylbenzoic acid group (group UP, 12 cases): ulinastatin 12 000 U/kg and aminomethylbenzoic acid 10 mg/kg was added into the priming solution; aminomethylbenzoie acid group (group P, 12 cases): aminomethylbenzoic acid 10 mg/kg was added into the priming solution. Results There was no significant difference in CPB time and blood transfusion among three groups; the postoperative 24 h chest tube drainage in group UP was (443.3 ± 150.8) ml, in group P was (430.0 ± 178.3) ml and in group A was (290.0 ± 98.0) ml, there were significant differences between group UP, group P and group A (P < 0.05). There was 1 case of severe allergic reaction in group A. Conclusion Aprotinin, ulinastatin and aminomethylbenzoic acid, aminomethylbenzoic acid are effective in stabilizing blood fibrinolytic system and preserving platelet function during CPB, leading to less postoperative blood loss.

Objective To investigate the effect of extracorporeal shock wave therapy (ESWT) on early and mid-term knee osteoarthritis (KOA). Methods 70 patients were randomly assigned to ESWT group (n=34) or control group (n=36). The ESWT group was given shock wave on unilateral knee, while the control group accepted shock wave with the energy density of 0. They were evaluated with Visual Analog Scale (VAS) on movement, Lequesne Index and Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index before and 12 weeks after the intervention. Results The scores of VAS, Lequesne Index and WOMAC Osteoarthritis Index improved more in the ESWT group than in the control group after intervention (P<0.01). Conclusion ESWT is effective on KOA as a non-surgical treatment.

OBJECTIVETo investigate the effect of sphingosine kinase 1 (SphK1) on the proliferation, apoptosis, migration and invasion of colon cancer TH-29 cells and to explore its molecular mechanisms.

METHODSPhorbol 12-myristate 13-acetate (PMA) was used to induce the activity of SphK1 and N, N-dimethylsphingosine (DMS) was used to suppress the activity of SphK1. Cell prolieration and apoptosis were detected by MTT assay and flow cytometry, respectively. The migration and invasion capabilities of the cells were assessed in Transwell chambers. The activity of SphK1 was assayed by autoradiography. Western blot was used to evaluate the protein expression of SphK1, p38, phosphorylated p38 (p-p38) and SAPK/JNK.

RESULTSPMA and DMS were able to induce and suppress the activity and protein expression of SphK1 in a time-dependent manner, respectively. PMA enhanced and DMS suppressed the cell viability in a time- and dose-dependent manner. Being treated with 100 nmol/L PMA or 50 µmol/L DMS for 0, 6, 12, 24 h, the cell apoptosis rates of PMA group were (9.35 ± 0.84)%, (7.61 ± 0.48)%, (5.53 ± 0.76)% and (0.56 ± 0.33)%, contrastly, that of DMS group were (9.18 ± 0.94)%, (12.06 ± 1.41)%, (19.80 ± 2.36)% and (31.85 ± 3.60)%, respectively. Compared with the control group, the cell migration and invasion capabilities of the PMA group were significantly enhanced, and that of the DMS group were significantly suppressed. The migration cell number of control, PMA and DMS groups were 68.75 ± 6.15, 109.33 ± 11.63 and 10.83 ± 2.48, the invasion cell number of control, PMA and DMS groups were 55.42 ± 4.50, 90.58 ± 7.06 and 9.58 ± 2.39, respectively. With the elevating activity and expression of SphK1, the protein expressions of p38, p-p38 and SAPK/JNK were strikingly suppressed. On the contrary, after treating with DMS the protein expressions of p38, p-p38 and SAPK/JNK were enhanced.

CONCLUSIONSSphK1 potently enhances the prolieration, migration and invasion of colon cancer HT-29 cells, meanwhile suppresses the cell apoptosis. The suppressing of the p38 and SAPK/JNK signalling pathways may be one of its molecular mechanisms.

Objective To assess the diagnostic value of combined testing of urinary bladder cancer antigen(UBC),hyaluronic acid(HA)and survivin in the detection of bladder cancer.Methods This study included 64 bladder cancer patients and 20 urinary benign disease patients.The examinations of urine UBC by enzyme-linked immunosorbent assay(ELISA),HA by radioimmunology assay,survivin by RT-PCR and urine cytology were performed in them.Results The sensitivity of UBC(85.9%,55/64),HA (89.1%,57/64)and survivin(93.8%,60/64)was significantly higher than that of urine cytology (40.6%,P＜0.01).The specificity of UBC,HA,survivin and urine cytology was 85.0%(17/20),80.0% (16/20),95.0%(19/20)and 95.0%(19/20),respectively;there was no significant difference among these 4 methods(P＞0.05).The sensitivity of UBC,HA and survivin was also significantly higher than that of urine cytology in different histologic stages and grades(P＜0.05).The sensitivity of UBC and survivin was not significantly different among different histologie stages and grades(P＞0.05).With regard to HA test, the sensitivity in G_2 and G_3 groups was significantly higher than G_1 group(P＜0.01),but there was no differ- ence between G_2 and G_3 groups(P＞0.05);and no difference among different histologic stages(P＞0.05). However,the sensitivity of cytology was improved with the higher grade of bladder cancer(P＜0.01);there was no difference among histologic stages(P＞0.05),By combined use of UBC,HA and survivin,both the sensitivity and specificity were 100%.Conclusions The study indicates that UBC,HA and survivin are better diagnostic markers for the early detection of urinary bladder cancer.These tests are simple,feasible and noninvasive with higher sensitivity and specificity.In addition,combined use of them can improve the diag- nostic sensitivity and specificity.

BACKGROUND:Esophagectomy is a very important method for the treatment of resectable esophageal cancer, which carries a high rate of morbidity and mortality. This study was undertaken to assess the predictive score proposed by Ferguson et al for pulmonary complications after esophagectomy for patients with cancer. METHODS:The data of patients who admitted to the intensive care unit after transthoracic esophagectomy at Cancer Hospital of Chinese Academy of Medical Sciences and Peking Union Medical College between September 2008 and October 2010 were retrospectively reviewed. RESULTS:Two hundred and seventeen patients were analyzed and 129 (59.4％) of them had postoperative pulmonary complications. Risk scores varied from 0 to 12 in all patients. The risk scores of patients with postoperative pulmonary complications were higher than those of patients without postoperative pulmonary complications (7.27±2.50 vs. 6.82±2.67;P=0.203). There was no significant difference in the incidence of postoperative pulmonary complications as well as in the increase of risk scores (χ2=5.477,P=0.242). The area under the curve of predictive score was 0.539±0.040 (95％CI 0.461 to 0.618;P=0.324) in predicting the risk of pulmonary complications in patients after esophagectomy. CONCLUSION:In this study, the predictive power of the risk score proposed by Ferguson et al was poor in discriminating whether there were postoperative pulmonary complications after esophagectomy for cancer patients.

BACKGROUND:Readmission to intensive care unit (ICU) after discharge to ward has been reported to be associated with increased hospital mortality and longer length of stay (LOS). The objective of this study was to investigate whether ICU readmission are preventable in critical y il cancer patients. METHODS:Data of patients who readmitted to intensive care unit (ICU) at National Cancer Center/Cancer Hospital of Chinese Academy of Medical Sciences (CAMS) and Peking Union Medical College (PUMC) between January 2013 and November 2016 were retrospectively collected and reviewed. RESULTS:A total of 39 patients were included in the final analysis, and the overall readmission rate between 2013 and 2016 was 1.32％ (39/2,961). Of 39 patients, 32 (82.1％) patients were judged as unpreventable and 7 (17.9％) patients were preventable. There were no significant differences in duration of mechanical ventilation, ICU LOS, hospital LOS, ICU mortality and in-hospital mortality between patients who were unpreventable and preventable. For 24 early readmission patients, 7 (29.2％) patients were preventable and 17 (70.8％) patients were unpreventable. Patients who were late readmission were all unpreventable. There was a trend that patients who were preventable had longer 1-year survival compared with patients who were unpreventable (100％ vs. 66.8％, log rank=1.668, P=0.196). CONCLUSION:Most readmission patients were unpreventable, and all preventable readmissions occurred in early period after discharge to ward. There were no significant differences in short term outcomes and 1-year survival in critically ill cancer patients whose readmissions were preventable or not.

OBJECTIVE: To determine the relationship between intravoxel incoherent motion (IVIM) imaging derived quantitative metrics and serum soluble CD40 ligand (sCD40L) level in an embolic canine stroke model. MATERIALS AND METHODS: A middle cerebral artery occlusion model was established in 24 beagle dogs. Experimental dogs were divided into low- and high-sCD40L group according to serum sCD40L level at 4.5 hours after establishing the model. IVIM imaging was scanned at 4.5 hours after model establishment using 10 b values ranging from 0 to 900 s/mm². Quantitative metrics diffusion coefficient (D), pseudodiffusion coefficient (D*), and perfusion fraction (f) of ischemic lesions were calculated. Quantitative metrics of ischemic lesions were normalized by contralateral hemisphere using the following formula: normalized D = D(stroke) / D(contralateral). Differences in IVIM metrics between the low- and high-sCD40L groups were compared using t test. Pearson's correlation analyses were performed to determine the relationship between IVIM metrics and serum sCD40L level. RESULTS: The high-sCD40L group showed significantly lower f and normalized f values than the low-sCD40L group (f, p < 0.001; normalized f, p < 0.001). There was no significant difference in D*, normalized D*, D, or normalized D value between the two groups (All p > 0.05). Both f and normalized f values were negatively correlated with serum sCD40L level (f, r = −0.789, p < 0.001; normalized f, r = −0.823, p < 0.001). However, serum sCD40L level had no significant correlation with D*, normalized D*, D, or normalized D (All p > 0.05). CONCLUSION: The f value derived from IVIM imaging was negatively correlated with serum sCD40L level. f value might serve as a potential imaging biomarker to assess the formation of microvascular thrombosis in hyperacute period of ischemic stroke.

OBJECTIVETo explore the impact of ideal health behaviors and health factors on the detection rate of the carotid plaques.

METHODSSubjects with previous stroke, TIA, myocardial infarction were excluded from the study. A total of 5852 employees (active and retired employers from Tangshan Kailuan company) aged 40 years and over were included through stratified random sampling. Information was obtained from the unified questionnaire, measurements of blood biochemistry and carotid artery ultrasonography.

RESULTS(1) The carotid artery plaque detection rates were 67.0%, 52.3%, 50.5%, 44.3%, 37.2%, 31.9%, 26.1% and 4.2% in the groups with 0, 1, 2, 3, 4, 5, 6 and 7 components of ideal cardiovascular health behaviors and health factors, respectively. (2) The carotid artery plaques total burden score [TBS: M (Q1, Q3)] were 7(7,7), 7(5,7), 7(5,7), 5(3,5), 5(3,5), 5(3,5), 3(3,3), 3(3,3) in the groups with 0, 1, 2, 3, 4, 5, 6 and 7 components of ideal cardiovascular health behaviors and health factors, respectively. (3) Multiple logistic regression analysis showed that 3, 4, 5 and greater than 5 components of ideal cardiovascular health behaviors and health factors were protective factors against carotid plaques compared to less than 2 components of ideal cardiovascular health behaviors and factors (all P < 0.05), the OR (95%CI) values were 0.78 (0.62 - 0.98), 0.53(0.62 - 0.98), 0.52 (0.39 - 0.71) and 0.40 (0.25 - 0.64), respectively.

CONCLUSIONIncreasing ideal cardiovascular health behaviors and factors are negatively linked with the detection rate and TBS of the carotid plaques.

OBJECTIVETo study the characteristics of inheritance and epidemiology of gallstone disease in one pedigree.

METHODSA gallbladder disease-specific questionnaire was administered to all family members to ascertain histories of cholecystectomy and other medical conditions as well as anthropometrical data. Laboratory examination and ultrasonography were performed to determine the existence of gallstone.

RESULTSOne hundred and thirteen members of four generations in the index family were enrolled in the study. The prevalence of gallstone in females (34.48%) was higher than in males (23.64%) but with no significant difference. The prevalence in the second and third generations (52%) was higher than in others (20%) (P < 0.05). The heritability and standard error showed as 86.38% +/- 46.46% in I generations. Body mass index, histories of hypertension, hyperlipidemia and blood glucose were positively related to gallstone disease (P = 0.012, < 0.01, 0.017, 0.043, respectively) in this family. Gallstone disease was not significantly related to history of diabetes, daily alcohol or diet habit. Plasma cholesterol and triglyceride levels were not correlated with gallstone disease.

CONCLUSIONGallstone disease presented aggregation in the family and was in accordance with the characteristics of autosomal dominant inheritance. Being female, obesity, hypertension and history of hyperlipidemia might serve as risk factors to this family.
