Objective To evaluate the risk factors for healthcare-associated infection (HAI)in patients in depart-ment of cardiology.Methods Clinical data of inpatients were performed retrospective case-control analysis,patients with HAI were as case group,while without HAI were as control group,factors for HAI between two groups were compared.Results 117 cases of HAI occurred among 2 308 patients,infection rate was 5.07%.The main infection site was respiratory tract (n=71 ,60.68%);a total of 90 pathogenic isolates were isolated,gram-negative bacteria, gram-positive bacteria,and fungi accounted for 72.22%(n=65),22.22%(n=20),and 5.56%(n=5)respective-ly.Univariate analysis revealed that 7 variables were risk factors for HAI,multivariate non-conditional logistic re-gression analysis revealed that independent risk factors for HAI were age,cardiac function classification,serum al-bumin level,and invasive operation.Conclusion HAI rate is higher among cardiology inpatients,which is related to many factors.Attention should be paid to the elderly,long term hospitalization,heart failure correcting,treatment for complications,reducing of invasive procedure,and strict sterile manipulation.

Objective To sum up the experience of laparoscopic assisted radical resection for colorectal cancer. Methods Radical resection was operated on 40 patients with colorectal cancer under laparoscope. According to the Dukes’ classification, 21 patients were classified as stage A, 16 patients as stage B and 3 patients, stage C.There were 2 cases of cecum cancer, 4 cases of ascending colon cancer, 13 cases of sigmoid colon cancer, and 21 cases of rectum cancer. Results Laparoscopic assisted operations were accomplished in all the 40 patients. The operation time was 110.8?23.5 min and the intraoperative blood loss was 150.4?23.2 ml. The patients began to ambulate 12.2?3.8 hours after the surgery and the time to first passing flatus was 39.3?4.2 hours. Follow- up for 2～72 months (mean, 38.5 months) found no metastasis, local recurrence, and port or incision implantation in all the patients but one,who refused chemotherapy and had a cancer recurrence one year after surgery. Conclusions Laparoscopic radical resection is applicable to colorectal cancer at Dukes’ stage A, B, or C, in which the lymph nodes can be removed as thoroughly as open radical surgery.
