Objective To improve the diagnosis of metastatic adrenal carcinomas. Methods 123 cases of primary canc-er which had been proved by autopsy in recent 10 years were reviewed. 23 cases of metastatic adrenal carcinomas werefound in all cases,the metastatic being unilateral in 20 and bilateral in 3. Results All the 23 cases of metastatic adrenal-carcinomas had been found missed diagnosis. Conclusion 16 cases are from lung cancer,among which 8 cases are smallcell lung cancer. It is important to prevent metastatic adrenal carcinomas from small cell lung cancer.

Objective To explore the expression levels and significance of Caveolin-1 and proliferating cell nuclear antigen (PC-NA) in esophageal squamous cell carcinoma .Methods Immunohistochemical SP method was used to detect the expression levels of caveolin-1 and PCNA in 150 cases of esophageal squamous cell carcinoma and 35 cases of normal esophageal squamous cell . Results The expressions of Caveolin-1 in esophageal carcinoma was significantly higher than in normal esophageal mucosa (P<0 .05) ,caveolin-1 was related to lymph node metastasis ;The expressions of PCNA in esophageal carcinoma was significantly higher than in normal esophageal mucosa(P<0 .05) ,PCNA was related to age ,lymph node metastasis and tumor size .The expression of Caveolin-1 was positively correlated with PCNA (r=0 .266 ,P<0 .05) .Conclusion Caveolin-1 and PCNA overexpression might be related to the occurrence ,development and metastasis of esophageal squamous cell carcinomas .

Objective:To retrospectively study the curative effect of Vbeam 595nm pulsed dye laser(PDL)in treating the mid-term infantile hemangiomas(IHs),and analyze and explore the possible influencing factors of that.Methods:A total of 219 IHs patients who underwent PDL treatment in Tangshan Maternal and Child Health Care Hospital from January 2020 to December 2022 were selected,and they received follow-up at least 6 months.The relationship between the treatment effect and the month age,location,thickness of hemangioma and the number of treatments was analyzed.Results:The median month age of the 219 pediatric children was 7 months,and the average month age of them was(4-10)months,and there was a total of 219 lesions.There were no statistically significant differences in the general data such as month age and the characteristics of lesion between different genders(P＞0.05).The overall effective rate of treatment was 92.7%,and the median number of treatments was 3 times,and the average number of treatments was(2-4)times.There were no statistically significant differences in the comparisons of gender,the number of treatments and the treatment outcome(P＞0.05).The curative effects of 6 pediatric children were poor,whose month age was 13(8,19)months.The curative effects of 10 pediatric children were general,whose month age was 13(8,14)months.The curative effects of 31 pediatric children were favorable,whose month age was 8(4,10)months.The curative effects of 172 pediatric children were excellent,whose month age was 6(4,9)months.The difference of month age of pediatric children among different curative effect was significant(Z=24.863,P＜0.001),and the pediatric children with better curative effect had smaller month age.The treatment outcome of pediatric children with hemangioma was correlated with the thickness of lesion,the area size of lesion and the number of treatment(r=-0.32,-0.46,-0.46,P＜0.05),respectively.The effective treatment mainly focused on the treatments of the 2nd-4th times.The adverse reaction caused by treatment was skin erythema,and the rate of the total residual after six months of the complication was 5.48%.Conclusion:The treatment of 595nm PDL combined with dynamic cooling device(DCD)can provide a safe and effective treatment for IHs.Early intervention for IHs can improve the curative effect,and reduce the course of treatment,and further reduce the possibility of corresponding complications.

Objective To investigate the incidence and risk factors of acute kidney injury(AKI) requiring continuous renal replacement treatment(CRRT) in patients with acute type A aortic dissection after Sun's operation.Methods A retrospective analysis of consecutive patients with acute type A aortic dissection underwent Sun's operation in Beijing Anzhen Hospital,Capital Medical University from January 2009 to December 2015.These patients were divided into two groups according to whether had severe postoperative AKI requiring CRRT treatment:the dialysis group(AG,65 cases) and the control group(CG,618 cases),we compared the clinical outcomes of patients in two groups and analyzed the related risk factors.Results 50 patients(7.3％) died in hospital.Compared with patients in CG group,patients in AG group had higher age,more patients with preoperative coronary heart disease,pericardial tamponade,and higher rates of intraoperative coronary artery hypass surgery or valve surgery,the results were statistically different between the two groups(P ＜0.05).The patients in AG group had a higher mortality rate in hospital(26.2％ vs.5.3％),and the difference was statistically significant(P ＜0.001).The results of multiple regression analysis suggested that the age ＞ 50 years,preoperative history of pericardial tamponade,intraoperative need for combined coronary artery bypass grafting or valve surgery,and cerebral perfusion time ＞40 min were independent risk factors for CRRT treatment of postoperative severe AKI(P ＜0.05).Conclusion The incidence of severe AKI requiring CRRT treatment in patients with acute type A aortic dissection after Sun's operation was 9.5％,and the discharge survival rate in AG group was lower than that in CG group.An important way to reduce the incidence of severe AKI requiring CRRT after sun's surgery is to shorten the intraoperative cerebral perfusion time as much as possible.

Objective To evaluate the efficacy and safety of preoperative intra-aortic balloon pump(IABP) insertion in acute myocardial infarction(AMI) without cardiogenic shock(CS) patients receiving off-pump coronary artery bypass grafting ( OPCABG).Methods 444 consecutive AMI patients who underwent isolated OPCABG from January 2009 to December 2016 were enrolled.158 patients who underwent preoperative IABP placement(IABP group) and the other of 286 patients who did not have IABP placement(control group).The in-hospital mortality rate, postoperative complications, mechanical ventilation time, ICU stay and hospital length were compared between the two groups.Results The overall mortality was 5.0%.135 pairs of patients were matched.The preoperative IABP insertion showed benefits in postoperative survival rate compared with the control group(0 vs.5.9%, P＝0.004).However, patients with preoperative IABP were more likely to prolong duration of mechanical ventilation and ICU stay.The postoperative length of stay in hospital didn't show significant difference between the two groups.Conclusion Survival advantage was observed from preoperative IABP insertion in AMI patients without CS under-going OPCABG.

Objective:To investigate the safety and the efficacy of percutaneous and surgical approach in femoro-femoral veno-arterial extracorporeal membrane oxygenation (VA-ECMO) cannulation.Methods:All consecutive patients implanted with femoro-femoral VA-ECMO between January 2018 and December 2020 in Beijing Anzhen Hospital, Capital Medical University. Propensity score matching was used to compare outcomes of percutaneous and surgical groups while controlling for confounders.Results:Among the 276 patients who received femoro-femoral VA-ECMO (62 surgical and 214 percutaneous), propensity-score matching selected 52 pairs of patients with similar characteristics with mean age of(59.6±13.0)years old, in which 26 patients were female. There were a lower ECMO cannulation-associated complication (28.8% vs. 48.1%, P=0.044) and a lower hospital mortality (42.3% vs. 67.3%, P=0.010) in the percutaneous group. The circuit blood flow after ECMO initiation was similar in both groups[(3.3±0.8)L·min -1·kg -1 in percutaneous group vs. (3.2±0.7)L·min -1·kg -1 in surgical group, P=0.738]. The serum lactate was declined in both group after ECMO initiation[(5.4±5.8)mmol/L vs. (9.2±6.9)mmol/L, P<0.001 in percutaneous group; (6.3±6.2)mmol/L vs. (10.5±7.0)mmol/L, P=0.003 in surgical group]. Conclusion:Percutaneous approach is a safe and efficient technique in emoro-femoral VA-ECMO cannulation. Compared with surgical cannulation, percutaneous approach is associated with lower ECMO cannulation-associated complication and lower hospital mortality.
