Forkhead box A1 (FOXA1) is expressed in various organs,including breast,liver,pancreas,bladder,prostate,colon,ovary,lung and esophagus.The FOXA1 expression is associated with the growth and carcinogenesis of these organs.It is recently demonstrated FOXA1 plays a significant role in different biological processes including cell proliferation,differentiation,devolopment,carcinogenesis and the process of epithelial-mesenchymal transition (EMT) etc.Its expression is positively correlated with ER and PR expression,and it is demonstrate to be one of the most important favorate prognostic factors of breast cancer.

Objective To investigate the tracking neurofibra pathway from the hippocamlpal neurons to septal nucleus,and to explore the effects and mechanisms of ghrelin on the learning and memory in septal nucleus lesion rats.Methods Retrogradely tracing method was used to observe Fluorogold (FG) reaching sites in hippocampus.The septal nucleus was destructed by direct current using stereotactic technique.Step-down test and morris water maze were used to test the effects of learning and memory ability by means of microinjecting ghrelin into hippocampal CA1 area in rats.Results After injection of FG into septal nucleus,retrogradely labeled neurons and neurofibra were found in the hippocampal neurons with FG.Ghrelin injection of hippocampal CAI area could promoter learning and memory ability in rats.It showed that the escaped latent period was significantly lengthened ( (3.2 ± 0.9) s vs (6.9 ± 1.1 ) s,P ＜ 0.05) and the wrong numbers in 5 min were obviously decreased in escape response test; and the latency of looking for the plat was significantly shorter in morris water maze test ( 1.8 ±0.4vs 0.8 ± 0.1,P ＜ 0.05 ).However the effects above-mentioned on learning and memory was significantly weak after septal nucleus lesioning.It showed that the escaped latent period was markedly shortened ( ( 19.5 ±3.2)s vs ( 10.5 ± 2.1 ) s,P ＜ 0.05 ) and the wrong numbers in 5 min were obviously increased ( ( 3.9 ± 0.8 ) s vs ( 1.8 ±0.5 ) s,P＜0.05 ) in escape response test.The latency of looking for the plat was significantly lengthened in morris water maze (P＜0.05).Conclusion Ghrelin could elevate the learning and memory ability in hippocampus,and the effects may be related to the septal-hippecampus pathway.

To evaluate effects and mechanism of Captopril on BP of 2 -kidney, 1 -clip reno-vascular hypertensive rats ( 2K1C - RHR ), Platelets cytosolic free calcium, concentration ([Ca2+]i) and platelets aggregation (PAg) are measured. The results are as follows: [Ca2+ ]; and PAg increase significantly (P

BACKGROUND:The repair method of proximal humeral comminuted fractures in the elderly remains controversial. OBJECTIVE:To compare the recovery of shoulder joint function using the hemiarthroplasty of shoulder and locking proximal humeral plate fixation for complex proximal humeral fracture in the elderly. METHODS:A total of 22 elderly patients with complex proximal humeral fracture, who were treated from October 2012 to October 2014, were retrospectively analyzed. 12 cases underwent hemiarthroplasty, and 10 cases received locking proximal humeral plate fixation. Al patients were folowed up after treatment. X-ray films were rechecked during the folow-up. The recovery of shoulder function was evaluated with Neer score. RESULTS AND CONCLUSION:During final folow-up, no prosthetic loosening or avascular necrosis of humeral head was found in the shoulder hemiarthroplasty group, and the Neer score was (81±5) points. In the locking proximal humeral plate fixation group, there was fixator loosening in four cases and avascular necrosis of humeral head in three cases, and the Neer score was (69±5) points (P < 0.05). During repair, mean operation time was shorter in the shoulder hemiarthroplasty group than in the locking proximal humeral plate fixation group. The amount of bleeding was higher in the shoulder hemiarthroplasty group than in the locking proximal humeral plate fixation group (P > 0.05). These data suggest that locking proximal humeral plate fixation and shoulder hemiarthroplasty are effective repair methods for complex proximal humerus fractures, but the hemiarthroplasty had the advantage of early functional exercise and good recovery of shoulder joint.

The incidence of dextrocardia is lower. The dextrocardia is often associated with congenital anatomical abnormalities. The patient with normal cardiac structure of dextrocardia and severe coronary heart disease that needs coronary artery bypasss is rarer. This article summarizes the perioperative management and surgical experience of dextrocardia with bypass surgery via a clinical case.

Objective To investigate the risk factors of postoperative atrial fibrillation (POAF) in patients with on-pump coronary artery bypass grafting (ONCAB). Methods The clinical data of 200 patients with ONCAB were retrospectively analyzed. The patients were divided into POAF group (n=52) and non POAF group (n=148) according to the occurrence of POAF after operation. The perioperative data including age and gender of all patients were collected and analyzed. The index of opinion of statistical results was classified by two categories Logistic regression analysis, and the related risk factors of POAF were analyzed. The receiver operating characteristic (ROC) curves of the age, red blood cell (RBC), left atrial diameter (LAD) and left ventricular ejection fraction (LVEF) were analyzed in two groups. Results The incidence rate of POAF was 26%, mostly occurred in the postoperative period from 1 d to 3 d. Compared with non POAF group, the age, the proportion of patients with age≥62.5 years or older, the proportion of patients with LAD≥35 mm, left ventricular end-diastolic diameter and perioperative transfusion of RBC were increased in POAF group, and data of mechanical ventilation time, ICU stay time and hospitalization time were prolonged, but the LVEF level decrease ( P<0.05). Among them, the elderly (≥62.5 years), increased LAD (≥35 mm), the higher perioperative transmission amount of RBC were the independent risk factors of POAF after ONCAB, and the higher LVEF was a protective factor for ONCAB. The optimal thresholds for age, RBC, LAD and LVEF were 62.5 years, 1U, 35.5 mm, and 0.34. Conclusion The occurrence of POAF after ONCAB is related with age (≥62.5 years old),LAD≥35 mm and perioperative transfusion of RBC, which can be used as clinically to predict the occurrence of POAF.

Objective To summarize the experience of surgical treatment in patients with uremia and severe coronary artery disease, and reduce the perioperative risk thereof. Methods Sixteen chronic renal failure patients who were received haemodialysis and underwent coronary artery bypass grafting (CABG) during the period of February 2009 to December 2016 in Tianjin First Central Hospital were assessed in this retrospective study. Of the 16 patients, 8 patients and 6 patients were treated with off pump and on pump CABG respectively, one patient was treated with CABG and resection of ventricular aneurysm, and one patient was treated with CABG and tricuspid valve replacements. The renal function changes in preoperative and postoperative periods, 2-day and 1-week after surgery were observed. Echocardiography was used to evaluate cardiac function. The improvement of angina was recorded. Results Fourteen patients were successfully withdrawn from ventilator therapy within 24 h after surgery. The tracheal intubation was removed 65-hour after surgery in one patient. One patient died of multiple organ failure on the seventh day after surgery. The average length of ICU staying and in-hospital stay were (125.5 ± 21.6) h and (28.6 ± 7.4) days respectively. The serum creatinine (sCr) and blood urea nitrogen (BUN) were higher in two days after surgery than those before the operation (P < 0.05). Fifteen patients which followed up (the final follow-up date was February 2017) showing cardiac functionⅠ-Ⅱ, ejection fraction (EF)>0.40, and no angina occurred. Conclusion CABG is relatively safe for patients with end-stage renal disease and severe coronary artery disease. CABG can significantly eliminate angina symptoms with satisfactory clinical effect.

Objective To investigate the effects and mechanisms of valproic acid on brain edema,neurobehavioral outcome and inflammatory response after traumatic brain injury (TBI) in rats.Methods TBI animal models were established using Feeney's method.Fifty-four SD male rats,weighting 220-250 g,were randomly divided into 3 groups (n =18):sham operation group (group sham),traumatic brain injury group (group TBI) and valproic acid treatment group (group TBI + VPA).Experimental rats were treated with valproic acid (300 mg/kg,twice daily) by intraperitoneal injection.Rat behavioral outcomes were measured by modified neurologic severity score (mNSS) tests at day 1,3,and 7 after TBI.Brain water content was measured with wet-dry weight method.The blood cells infiltration into cerebral cortex were tested with immunohistochemistry staining against ED-1 for macrophage.Inflammatory cytokines (INF-γ,tumor necrosis factor-α,interleukin-6) were measured by Western blotting.The statistical analysis were performed by ANOVA and chi-square tests using the statistical software program SPSS 13.0.Results Compared with the Sham group,the levels of brain edema,mNSS and macrophage cell infiltration were significantly increased after TBI (all P =0.00).The expressions of inflammatory cytokines were also increased significantly (all P =0.00).Compared with the TBI group,TBI + VAP group had significantly lower brain water content[3day:(80.12 ±0.59)％ vs.(82.14 ±0.67)％,P=0.04;7day:(74.74 ±0.72)％ vs.(77.93 ±0.48)％,P=0.01],and mNSS scores [3 day:(10.53 ±0.32) vs.(11.74 ±0.48),P =0.02;7 day:(7.97 ± 0.32) vs.(10.73 ± 0.42),P =0.01].VPA suppressed macrophage cell infiltration into cerebral cortex [(36.44 ± 0.72) ％ vs.(25.93 ± 0.48) ％ P =0.00].Meanwhile,VPA inhibited the expressions of inflammatory cytokines (INF-γ,TNF-α,IL-6) (P ＜ 0.05).Conclusions Treatment with VPA markedly reduced brain edema and improved neurological outcomes after TBI,possibly mediated by inhibited TBI-induced cerebral inflammatory responses and macrophage cell infiltrating into cerebral cortex.

Objective To summarize the treatment experiences in patients with cardiac surgery-associated acute kidney injury (CSA-AKI). Methods The clinical data of 9 patients with acute renal injury after orthotopic heart transplantation in our hospital from January 2009 to July 2016 were retrospectively analyzed. Three patients were required the high-dose diuretics (furosemide, >80 mg/d) and six patients were received continuous renal replacement therapy (CRRT). The levels of serum creatinine (Cr) and estimated glomerular filtration rate (eGFR) were compared before and after heart transplantation and after the treatment of AKI. The quality of life was observed in patients in perioperative period. Results After the treatment of diuretics or CRRT, patients showed renal function recovery with significant decreased Cr levels and increased eGFR compared with the postoperation. The patients with diuretic therapy revealed a better eGFR recovery than those with CRRT. Conclusion CSA-AKI should be based on the severity of disease, and comprehensive treatment should be taken to reduce renal damage.

Objective To compare cognitive function and alexithymia between the schizophrenic patients treated with chlorpromazine and those treated with clozapine. Methods The patients with schizophrenia in stable condition that received maintenance treatment either with chlorpromazine or clozapine and normal control subjects were recruited (n=24 per group). Neuropsychological tests, including Digit Vigilance Test, Controlled Oral Word Association Test, Trail Making Test-A&B (TMT-A&B), Animal Naming Test, Stroop Color-Word Test, Block Design and Spatial Span Test were used to assess the participant’s cognitive function. The twenty-item Toronto Alexithymia Scale (TAS-20) were used to evaluate the participant’s alexithymia. Results The significant differences were found between the patients and the controls in all items of cognitive function and all factor scores of TAS-20 (P<0.05). There were no significant differences in all items of cognitive function and all factor scores of TAS-20 between chlorpromazine group and clozapine group (P>0.05). Multivari? ate linear regression analysis showed that in the clozapine group, attention function associated with the total score of TAS (β=-0.20, P<0.05), executive function associated with TAS factor 1 (β=-0.26, P=0.03), spatial function associated with TAS factor 2 (β=-0.24, P<0.01). In the chlorpromazine group, attention function associated with TAS factor 2 (β=-1.24, P<0.01), executive function associated with TAS factor 2 (β=-0.33, P=0.02). Conclusions Patients with schizophrenia in maintenance period have widely cognitive impairment and alexithymia, both of which are related to each other.
