Objective This paper aims to analyze the current situation of procurement project demonstration in public hospitals to enhance cost control capabilities and improve services provided by public hospitals.Methods This study took the project demonstration of equipment procurement at a specific tertiary hospital as an example to identify common defects in the pro-ject demonstration and enhance its effectiveness in public hospitals.Results The current project demonstration process in public hospitals lacked integration with the actual hospital situation,resulting in excessively long time for demonstration,low efficiency,and unclear responsibilities.Conclusion Adopting flexible forms,shortening the duration,expanding departmental involvement,and ensuring administrative departments serve clinics in an integrated manner are key to enhancing the project demonstration ca-pacity in public hospitals.

Objective To assess the effects of the risk factors of grafts from donors after cardiac death (DCD) on the prognosis of liver transplantation (LT).Methods In this retrospectively study,215 cases of LT using DCD donor grafts were performed at our institution from September 2013 to January 2017.Due to the loss to follow-up in 4 cases,211 cases were enrolled in the study.The following DCD donor data were collected:gender,age,primary disease,ABO blood type,body mass index (BMI),medical history (fatty liver,hypertension),ICU hospitalization time,mechanical ventilation time,warm ischemia time,cold ischemia time,and indexes of routine laboratory test before donation.Statistical analyses using the Kaplan-Meier method,log-rank test,multivariate step-wise Cox regression were performed.Results Of the 211 donors,univariate analysis showed that the overall 6-month,1-,and 3-year survival rate after DCD LT was 88％,84％,and 82％,respectively.Univariate analysis showed that donor serum sodium level ＜136 mmol/L (P =0.018) and cold ischemia time ＞9 h (P =0.013) were all significant risk factors affecting overall survival after DCD LT.Additionally,donor BMI ＞30 kg/m2 (P =0.011) and donor age ＞60 years (P =0.025) were significantly associated with postoperative complications.Multivariate analysis showed that donor serum sodium level (P=0.025) was an independent risk factor of survival after DCD LT.Conclusion To select suitable DCD liver allografts and control risk factors of donor can help to improve outcomes of recipients.

Objective To investigate the incidence of osteodystrophy induced by diving decompression in Yantai.Methods One hundred and seventy-one dive fishing personnel,who were hospitalized in our hospital,were selected as our research subjects.Paranasal sinuses,both shoulders,hips and knees had routine X-ray detection for study.Results Of all the patients,166 had a history of different degrees of joint pain and muscle pain.X-rays detection revealed that most divers were suffering from decompressed osteodystrophy.Conclusions With the extension of diving service,the incidence of decompressed osteodystrophy was increased gradually year by year.
