Objective To explore the influence of uncertainty in illness in compliance of respiratory function exer-cise and rehabilitation after surgery in patients with coronary artery bypass graft (CABG) surgery. Methods Mishel uncer-tainty in illness scale and compliance of respiratory function exercise scale were used to collect data in 108 patients with CABG. The correlation of the uncertainty in illness and compliance of respiratory function exercise was analyzed. Patients were divided into three groups (high score, medium score and low score groups) according to the detection of uncertainty in illness. Values of compliance of respiratory function exercise, postoperative care time, postoperative ventilation time, postop-erative hospital stay duration, 6-min walking test (6MWD) and left ventricular ejection fraction (LVEF) were compared be-tween three groups. Results The uncertainty in illness was in medium level (95.51±9.48) in patients with CABG surgery, which was negatively correlated with compliance of respiratory function exercise (r=-0.926, P<0.01). The postoperative venti-lation time and postoperative care time were less in low score group than those of medium score group and high score group. The compliance of respiratory function exercise, 6-min walking test and postoperative LVEF were better in low score group than those of medium score group and high score group. Conclusion Medical personnel should take targeted interventions to reduce the uncertainty in illness in patients, enhance the compliance of respiratory function exercise, reduce the postopera-tive complications and promote early recovery of patients.

[ ABSTRACT] AIM: To study the effect of adenosine A 2A receptor antagonist SCH58261 on hypoxic-ischemic brain damage ( HIBD) in a mature fetal rabbit model .METHODS:Pregnant New Zealand white rabbits at gestational day 29 were selected and were randomly divided into sham-operated group, hypoxic-ischemic group, SCH58261 0.04 mg/kg group, SCH58261 0.12 mg/kg group and DMSO group.The intrauterine rabbit HIBD model was established .All pregnant rabbits were subjected to cesarean section 24 h after the sham operation or experimental procedure to induce hypoxic-ische-mic injury in the fetus .The survival neonatal rabbits were kept in a neonatal incubator at 35℃.The general conditions of the newborn rabbits were recorded .The degree of neurobehavioral damage in the newborn rabbits was estimated by a neu -robehavioral scoring protocol .The concentration of SCH 58261 in the serum of pregnant rabbits , the serum of neonatal rab-bits and the brain tissues of neonatal rabbits was measured by mass spectrometry .The mRNA expression of Bcl-2/Bax and protein levels of p-P38 mitogen-activated protein kinase (MAPK) in the cortex, hippocampus and striatum area in the brain of the neonatal rabbits were determined by real-time PCR and Western blot .RESULTS:SCH58261 was detected in the se-rum and brain tissues of the newborn rabbits .The SCH58261 concentration was approximately 40 μg/L in the brain tissue of the newborn rabbits .The mRNA expression of Bcl-2 in the cortex , hippocampus and striatum of brain tissues in SCH58261 0.04 mg/kg group and SCH58261 0.12 mg/kg group was higher , and the mRNA expression of Bax was lower than those in HI group (P<0.05).The protein level of p-P38 MAPK in the cortex, hippocampus and striatum of brain tis-sues was reduced in SCH58261 0.04 mg/kg group and SCH58261 0.12 mg/kg group compared with HI group (P<0.05). The protein level of p-P38 MAPK in SCH58261 0.12 mg/kg group was a little lower than that in SCH 58261 0.04 mg/kg group (P<0.05).CONCLUSION: Adenosine A2A receptor antagonist SCH58261 attenuates hypoxia-ischemia induced neonatal brain injury by blocking adenosine A 2A receptor, subsequently inhibiting p-P38 MAPK phosphorylation to reduce neuronal apoptosis .

AIM: To investigate the effect of basic fibroblast growth factor (bFGF) on radiation-induced splenocytic apoptosis of mice. METHODS: At 14 h after whole body irradiation with 0.5 Gy and 1.0 Gy,splenocytes were cultured with and without bFGF,and splenocytic apoptosis was quantitatively analysed by flow cytometry. Cell proliferation was determined by the method of [3H]-TdR incorporation. RESULTS: bFGF(1 ?g/mL and 2 ?g/mL) could reduce the rate of cell apoptosis ,and promote the proliferation of splenocytes. CONCLUSION: bFGF could inhibit radiation-induced splenocytic apoptosis and promote the proliferation of splenocytes and then enhance body immunity.

Objective To evaluate the predictive effect of preoperative pressure-flow studies on the outcome of transurethral prostatectomy.Methods Sixty-three patients with benign prostatic hyperplasia(BPH) were evaluated by using pressure-flow studies,international prostate symptom score,uroflowmetry,and residual urine volume before and 3 months after surgery.The patients were divided into 3 groups(obstruction equivocal and unobstruction) according to the grade of pressure-flow.The outcome of transurethral prostatectomy were analyzed in each group with detrusor contractility(weak or normal).Results Treatment outcome could be predicted by using the grade of benign prostatic obstruction and detrusor contractility.The sensitivity of which was 73.5%,with a specificity of 88.5% and positive predictive value of 96.2%.Conclusions Urodynamic studies provide great predictive value of option in transurethral prostatectomy.

Objective To detect the PML-RARα fusion gene expression of APL patients with FISH and fluorescent quantitative PCR and discuss the sensitivity and specificity of two techniques. Methods The detection of the PML-RARα fusion gene expression of 75 APL patients with FISH and fluorescent quantitative PCR were carried out simultaneously. Results Eighty eight patients of primary and relapse or remission phases were examinated and total conformity rate was 96.59 %. Fourteen primary patients were detected and conformity rate was 100 %. Seventy four relapse or remission patients were detected and conformity rate was 95.95 %. Stem cell essays were detected for six times and conformity rate was 100 %. Conclusion The sensitivity of FISH and fluorescent quantitative PCR is identical for primary APL patients and FISH is more sensitive. But the sensitivity of FISH is weaker than that of fluorescent quantitative PCR for detection of residue disease.

Objective To investigate the effect of stage 1 acute kidney injury (AKI) on the prognosis of patients underwent cardiopulmonary bypass (CPB) cardiac operation. Methods A retrospective analysis was conducted. All patients aged ≥ 18 years who underwent cardiac operation with CPB admitted to Beijing Anzhen Hospital from July 1st, 2013 to December 31st, 2015 were enrolled. According to the standard of serum creatinice (SCr) of Kidney Disease Improving Global Outcomes (KDIGO) criteria, the AKI patients with stage 1 and non-AKI patients were served as the research objects. Perioperative clinical data of two groups were collected, and the prognosis was recorded during follow up to draw the Kaplan-Meier survival curve. Cox regression model was used to analyze the risk factors of prognosis in patients with stage 1 AKI experienced CPB during cardiac operation. Results A total of 5 823 patients were enrolled, of which 1 285 patients with AKI, and those in stage 1 was 998, accounting for 77.67% of total AKI patients; and 4 538 in non-AKI group. The mean follow-up period among survivors was (23.13±12.28) months. Compared with non-AKI patients, 30-day mortality of patients with stage 1 AKI was significantly increased [4.00% (40/998) vs. 0.40% (18/4 538), P < 0.01]. It was showed by Kaplan-Meier survival analysis that the cumulative survival rate of patients with stage 1 AKI was significantly lower than that of non-AKI patients (log-rank = 51.989, P < 0.001). It was showed by further subgroup analysis that the cumulative survival rate of patients with stage 1 AKI without serum creatinine (SCr) recovery was significantly lower than that of patients with SCr recovery from stage 1 AKI (log-rank = 43.580, P = 0.000). It was showed by Cox multivariate analysis that stage 1 AKI [hazard ratio (HR) = 2.725, 95% confidence interval (95%CI) = 1.810-4.230, P = 0.000] and prolonged CPB in patients undergoing cardiac operation (HR = 1.013, 95%CI = 1.001-1.017, P = 0.000), combined with coronary heart disease (HR = 1.046, 95%CI = 1.010-1.063, P = 0.005) and diabetes mellitus (HR = 1.060, 95%CI = 1.010-1.090, P = 0.002) were independent risk factors of death in patients undergoing CPB during cardiac operation. Conclusion Stage 1 AKI is the main stage of AKI and it is independently related to all-cause mortality in patients underwent cardiovascular operation using CPB.

Objective To investigate the relationship between apoptcsis, expressions of VEGF and clinicopathological characteris- tics, and prognosis in esophageal squamous cell carcinoma (ESCC). Methods Sixty-one surgical specimens of primary esophageal squa- mous cell carcinomas were examined for VEGF by immunohistochemical staining (S-P). Apoptcsis was determined by TUNEL (TdT media- ting dUTP-biotin nick end-labeling) method. Clinicopathologic features were examined by histopathology. The prognostic impacts of these pa- rameters were analyzed by univariate and survival analysis. Results AI and VEGF were well correlated with differentiation, TNM stage. Lower tumor differentiation and higher TNM stage were related to decreasing AI and VEGF. In addition, VEGF in the groups of invasion be- yond muscularis and lymph node metastasis is significant higher than that in invasion reaching muacularis and no lymph node metastasis (P <0.01). But there were no significant correlation between AI and invasion( P>0.05). The simple-factor analysis results showed that the decrease of AI, VEGF, lymph node metastases, lower tumor differentiation, and invasion reaching muscularis were related to decrease of sur- vival rate. However, multivariate Cox analysis demonstrated that only AI and VEGF were the significant prognostic factors. Conclusions Apoptosis and angiagenesis participate in ESCC and promote its growth. VEGF is related to angiogenesis of ESCC. The increase of VEGF may promote invasion and lymph node metastasis. AI and VEGF are significant prognostic factors in ESCC.
