Conclusion It′s no affect for diagnosis to improve children′s head CT scanning parameter, and leads reduction of CT dosage obviously.

OBJECTIVE To understand the resistant bacteria infection condition of earthquake casualty and provide evidence for reducing their transmission in hospital.METHODS The staff members of Department of Hospital Infection Management monitored the bacteria cultures and report 38 resistant bacteria infective wounded every day.Set up the system measures to manage resistant bacteria infection of earthquake casualty and monitored,guided and checked the implement countermeasures.RESULTS Among 419 samples,there were 70 resistant bacteria and 97.1% were G-bacteria,the main pathogens were Acinetobacter baumannii,Pseudomonas aeruginosa,Enterobacter cloacae,Klebsiella pneumoniae,and Escherichia coli.The main infective sites were respiratory tract and wounds.The resistant bacteria had the high drug resistance to the third and fourth cephalosporins,aminoglycosides and sulfonamides.The sensitive rate to amikacin,gentamicin,imipenem,piperacillin/tazobactam,sulfamethoxazole/trimethoprim compound,tobramycin and nitrofurantoin.CONCLUSIONS Real-time monitoring the earthquake casualty with resistant bacteria infection can find the infective wounds in time and make effective intervention measures.It is the important method to prevent and control the hospital infection.

Objective:To investigate the status of rumination in patients with primary glaucomatous visual field defect and explore the influencing factors.Methods:Totally 267 patients with primary glaucomatous visual field defect were selected via convenience sampling method. Invasive rumination, purpose rumination, and self-management behaviors among different visual field were compared. The main influencing factors of invasive rumination and purpose rumination were analyzed.Results:Total score of rumination in patients with primary glaucomatous visual field defect was (29.90±5.58) points, average item score of self-management behaviors was (2.81±0.31) points. There were no significant difference in invasive rumination, purpose rumination, self-management behaviors among different visual field ( P>0.05). Accidental injury, life adjustment, income of family per mouth and degree of education could explain 30.7% of the total invasive rumination variation; disease management, body function promotion and accidental injury could explain 11.1% of the total purpose rumination variation. Conclusions:Rumination and self-management behaviors in patients with primary glaucomatous visual field were at a lower middle level and middle level respectively. Medical staff should attach importance to assess the invasive rumination among these patients with accidental injury, poor ability of life adjustment, low income of family per mouth and low degree of education. Through lowering the negative experience, changing the cognitive and taking correct self-management behaviors, then prognosis of disease would be improved.

OBJECTIVE: To observe the clinical effects of Xinfeng Capsules (XFC), a traditional Chinese medicine for invigorating the spleen to resolve dampness and dredging collaterals, on patients with rheumatoid arthritis (RA) and anemia, and to investigate its mechanism. METHODS: Forty patients with RA and anemia were divided into three groups: XFC-treated group (n=20), Tripterygium glycosides Tablets (TGT)-treated group (n=10) and methotrexate (MTX)-treated group (n=10). The patients in each group took corresponding medicine for three months. The response rates of the three groups were evaluated after treatment. The general symptoms and specific signs and symptoms of RA were observed before and after the treatment. The indexes of blood routine examination and some other laboratory indexes such as erythrocyte sedimentation rate (ESR), and blood levels of rheumatoid factor (RF), iron, C-reaction protein (CRP), immunoglobins (Ig), complements 3 and 4, tumor necrosis factor-alpha (TNF-alpha), interleukin-10 (IL-10) and erythropoietin (EPO) were all examined and compared before and after treatment. RESULTS: The total response rate in the XFC-treated group was similar to those both in the TGT-treated and MTX-treated groups. The effects on relieving specific symptoms of RA in the three groups were also similar. The ESR and serum levels of RF, CRP, IgG, IgA and IgM were all decreased after treatment as compared with those before treatment in the three groups, and there were no significant differences among those laboratory indexes in the three groups after treatment. The XFC displayed more obvious effects on improving the general symptoms of patients with RA and anemia, increasing the blood levels of hemoglobin, iron and IL-10, while decreasing the serum level of TNF-alpha and regulating the serum EPO level, as compared with those in the TGT-treated and MTX-treated groups. CONCLUSION: The XFC for invigorating the spleen to resolve dampness and dredging collaterals was developed on the basic principle of regulating spleen. It can obviously improve the symptoms and laboratory indicators of RA. Such effects may be related to maintaining the balance of cytokines, regulating the serum level of EPO and increasing the serum iron level in patients with RA and anemia.
