Objective To monitor the hospital computer room in real time; ensure the normal running of hospital information system; overcome the disadvantages of wired monitor system. Methods Zigbee was used to build a wireless sensor network. Wireless monitor system for hospital computer room was realized. Results By exerting the advantages of zigbee, hospital computer room was monitored more effectually and the workload of the computer room keeper was reduced. Conclusion Using Hospital computer wireless monitor system based on zigbee can achieve the uniform management and monitoring effectually.

Objective To supervise the execution process of medical orders,prevent and avoid malpraxis,improve the security of the nursing action.Methods On the demand of preventing and reducing malpraxis,the system structure and software design were implemented based on RFID and wireless technology.Results The functions of real-time examining and affirming were achieved in every step of medical orders,including unique identification for the patient identification,medicine and blood bag,etc.Conclusion The system can be ensured the security of patients,improved the quality of medical care,reduced the malpraxises and made great contribution for medical care.

Objective To analyze the clinical characteristics of bloodstream infection in patients with immune function inhibition. Methods A retrospective analysis was conducted. 234 patients with bloodstream infection admitted to intensive care unit (ICU) of the Affiliated Drum Tower Hospital of Nanjing University Medical School from August 1st in 2015 to December 31st in 2017 were enrolled. According to the immune function on the day of bloodstream infection, they were divided into normal immune function group [human leukocyte antigen DR (HLA-DR) > 30%, n = 144] and immunosuppression group (HLA-DR ≤30%, n = 90). The gender, age, primary disease, complication, acute physiology and chronic health evaluationⅡ (APACHEⅡ) with 24 hours after ICU admission, sequential organ failure assessment (SOFA) score, etiology, infection parameters on the day of bloodstream infection [peak temperature, white blood count (WBC), neutrophils ratio, procalcitonin (PCT), and C-reactive protein (CRP)] and prognosis parameters (bacterial clearance time, the length of ICU and hospital stay, 28-day mortality) between the two groups were analyzed. Results 234 patients were enrolled in the final analysis, including 132 males and 102 females, with an average age of (60.5±18.4) years old. Severe pneumonia and abdominal infection were the main causes of primary diseases. There was no significant difference in gender composition, age, APACHEⅡ, SOFA score, other complications and primary morbidity between the two groups except that the proportion of malignant tumors in the immunosuppressive group was higher than that in the normal immune function group [43.3% (39/90) vs. 41.7% (60/144), P < 0.05]. Compared with the normal immune function group, the Gram-positive cocci infection rate in the immunosuppressive group was significantly lowered [40.0% (36/90) vs. 56.2% (81/144)], Gram-negative bacilli infection rate [50.0% (45/90) vs. 39.6% (57/144)] and fungus infection rate [10.0% (9/90) vs. 4.2% (6/144)] were significantly increased (both P < 0.05). The levels of WBC, neutrophils ratio, and PCT on the day of bloodstream infection in the immunosuppressive group were significantly lower than those of normal immune function group [WBC (×109/L): 10.2±2.1 vs. 13.5±3.6, neutrophils ratio: 0.87±0.17 vs. 0.96±0.22, PCT (μg/L): 1.3±1.1 vs. 4.7±2.1, all P < 0.05], but no significant difference in the peak temperature (℃: 38.5±1.7 vs. 38.9±1.3) or CRP (mg/L: 134.0±42.6 vs. 164.0±55.8) was found as compared with normal immune function group (both P > 0.05). Compared with the normal immune function group, the bacterial clearance time in the immunosuppressive group was significantly prolonged (days: 16.0±10.1 vs. 12.3±4.7), 28-day mortality was significantly increased [61.1% (55/90) vs. 44.4% (64/144)] with statistical significances (both P < 0.05), but no significance was found in the length of ICU stay (days: 21.0±17.1 vs. 18.7±10.4) or the length of hospital stay (days: 36.0±28.1 vs. 33.8±16.8, both P > 0.05). Conclusion Gram-negative bacilli was the main pathogen of bloodstream infection in immunosuppressive patients, and the fungal infection rate was high, inflammation reaction was not obvious, bacterial clearance time was long, and prognosis was poor.
