This paper aims to discuss how to reasonably make use of the procurement resources,measurement resources,maintenance resources,management resources,financial resources,environment resources and other auxiliary resources.The integration of medical equipment and various resources can raise medical equipment index and improve hospital efficiency and benefit.

By comparing the current methods of public bidding,a new method for inviting public bidding is introduced including its basic process,organization methods and concrete implementation steps.What's more,a series of related things are discussed in detail such as the name lists of invitees,the requirement and technical parameters in inviting public bidding,time and place,specialists in judge group,confirmation of successful bidder,publicizing advice note for successful bidder,etc.The main purpose is to save the medical cost in hospital and make full use of the existing resources.It is proved to be feasible in practice.

Several common methods of remittance for foreign trade are introduced in the course of purchasing imported medical equipment.The advantages and disadvantages of every remittance method are also elaborated.The best method should be chosen by hospitals according to the actual situations so as to lower or avoid unnecessary risks and raise economic benefits.

The computerization of medical consumable warehouse-in&out has become a general trend of modern medical consumable management.The medical consumable management software in No.1 Military HIS is modified and improved so as to be integrated with practice for better management of medical consumable.

The bidding method based on network platform is introduced. Combining internet resource with invite tender, a set of perfect system on hospital internet bidding is built to expand the number and scope of suppliers. To meet the requirement of hospitals, the corresponding suppliers are selected and the work efficiency of invite tender is improved. The whole level of material centralized purchasing is advanced and purchasing cost can be reduced by developing system of internet bidding.

Objective To investigate the effects of Qiliqiangxin capsule on serum concentration of adiponectin (APN) and heart function in patients with uremia combined with heart failure. Methods Uremia patients combined with heart failure were randomly divided into treatment group and control group , both of which were given anti-failure routine therapy. The patients in treatment group were treated with Qiliqiangxin capsule for 8 weeks and those in control group with placebo. The New York Heart Association (NYHA) heart function classi-fication, left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left ventricular ejection fraction(LVEF), and the levels of APN were observed before and after treatment. Results The level of APN in uremic patients combined with heart failure was significantly higher than that in normal subjects. With the increase in the class of NYHA heart function, the serum concentrations of APN increased, but the difference was not significant(P > 0.05). After 8 weeks′ treatment, the effective rate in treatment group was higher than that in control group (P < 0.05). LVEDD and LVESD in both groups decreased significantly. LVEF in both groups increased, but serum concentration of APN decreased significantly. More obvious effects were observed in treatment group (P < 0.05). Conclution Qiliqiangxin capsule could significantly reduce the level of APN and improve heart function in patients with uremia combined with heart failure.

Objective To study the effect of formaldehyde exposure on DNA-protein crosslinks (DPC) in buccal mucosa cells in students who were taking anatomy course.Methods The modified SDS-KCl precipitation assay published by Zhitkovich and Costa in 1992 was applied to detect DNA-protein crosslinks in human cells.And this method has been used to explore DPC induced by different pollutants in numerous studies.37 medical students (20 males and 17 females) aged 19.24?1.09 (mean?standard deviation) and 40 students (20 males and 20 females) in natural science college aged 19.55?0.99 (mean?standard deviation) were studied.The frequency of exposure to formaldehyde was 6 h per week in exposed group.Results Concentrations of formaldehyde in anatomy laboratory ranged from 0.42 to 1.57 mg/m3.Exposure to formaldehyde resulted in an increase of DNA-protein crosslinks.The percentage (mean?standard deviation) of DNA-protein crosslinks in exposed and nonexposed students were 25.72%?6.48% and 22.88%?5.34% respectively(P0.05).Conclusion The result of the present study suggests that formaldehyde exposure in medical students increases the frequency of DNA-protein crosslinks in buccal mucosa cells and females may be more sensitive to formaldehyde exposure.

Objective To investigate the efficacy and safety of intravitreous injection with triamcinolone acetonide (TA) for cystoid macular edema (CME) due to central retinal vein occlusion (CRVO). Methods Fourteen eyes of 14 patients with CME due to CRVO underwent intravitreous injection with 0.1 ml TA (40 mg/ml). Best-corrected visual acuity, intraocular pressure (IOP), slitlamp examination, fundus fluorescein angiography, and optical coherence tomography (OCT) were performed on the patients before and after the injection. The follow-up period was 10-22.4 months, with the mean of 15.9 months. Results The average visual acuity was 0.1 before the treatment; while 1 month and 3 months after the injection, the visual acuity of all of the patients improved, including ≥0.2 in 71.43% and 63.6% of the patients, respectively, and ≥0.5 in 42.9% and 27.3%, respectively. After then, the visual acuity of some patients decreased, and in the final visit, 4 eyes (28.6%) had a visual acuity of ≥0.2, and 1 eye (7.1%) of ≥0.5. Compared with that before the treatment, the visual acuity of 10 (71.4%) eyes improved and 4 (28.6%) eyes declined. One month after the treatment, the macular edema disappeared in 10 eyes (71.4%) and alleviated in 4 (28.6%). In the final visit, macular edema disappeared in 4 eyes, alleviated in 9, and aggravated in 1. In the follow-up duration, high IOP [22.3-40.1 mm Hg (1 mm Hg=0.133 kPa)]. In the final visit, posterior subcapsular cataract was found in 7 eyes. Conclusion Intravitreous injection with TA may be effective in reducing CME and enhancing the visual acuity in a short term with high IOP in some eyes. In the long-term follow-up period, the rate of recurrence of CME and incidence of posterior subcapsular cataract is high.

Objective To summarize the experience of surgical treatment and to explore the oper-ation method choice of ascending aortic aneurysm caused by Marfan Syndrome. Methods The clinical da-ta of 16 patients from 2005 January to 2011 November were retrospectively analyzed. Results Among all, there was no operative mortality,but 6 cases of early postoperative complications(37. 5%),including 2 ca-ses of arrhythmia,2 cases of pulmonary infection,1 case of renal insufficiency and 1 case of pneumothorax. The follow-up time was 12~63(25 ± 9)months. During follow-up,2 patients died(12. 5%),1 due to rup-tured abdominal aortic aneurysms and 1 due to renal failure. Besides there were 2 cases of anticoagulation complications and 1 case of coronary heart disease. Conclusion Although sparing aortic root replacement of aortic valve has similar curative effect as Bentall operation and avoids the mechanical valve-related com-plications,the indications are relatively strict. Bentall operation is still the first choice for severe patients.

Objective To investigate the clinical value of neutrophil-to-lymphocytc ratio(NLR) in identifying blood stream infection caused by different pathogens and for differentiating coagulase negative staphylococcus(CNS)bloodstream infection and contamination.Methods Medical records of 500 patients who underwent blood culture test and routine blood test at the same time were retrospectively analyzed,blood culture negative group 356 patients,blood culture positive group 144 patients,which included Gram-negative group,Gram positive group,fungi group,CNS bloodstream contamination and mingled group.Collected the results and calculated the NLR at the same time.NLR were applied by t test of each group.ROC curve was used to determine the cut off value of NLR.Results ①Mean values of NLR in negative blood culture,blood stream infection group,CNS bloodstream infection and contamination were 6.12,13.15,10.11 and 6.24.NLR had statistical difference between negative blood culture and blood stream infection group,CNS bloodstream infection group and contamination group (P＜0.05).②Mean values of NLR in and fungi group were 15.33,11.63 and 10.58,respectively.NLR had statistical difference between Gram-positive bacteria group and Gram-negative bacteria group (P＜0.05).NLR had no differences among Gram-positive bacteria (15.33) and Gram negative bacteria (11.63) compared with (10.58) fungi respectively (P＞0.05).③The area under the curve of NLR predicting a positive blood culture,distinguishing Gram-positive bacteria and Gram-negative bacteria,differentiating CNS bloodstream infection and contamination were 0.86,0.60 and 0.75,respectively.The optimal cut off values of NLR for predicting a positive blood culture,distinguishing Gram-positive bacteria and Gramnegative bacteria,differentiating CNS bloodstream infection and contamination were 10.45,7.50 and 8.10 respectively.Conclusion NLR is highly effective in distinguishing blood stream infection and differentiating CNS bloodstream infection and contamination.
