Sepsis is a major problem in the pediatric critical care medicine.The related research indi-cates that the nutrition risk may be one of the risk factors that affect the incidence and mortality of sepsis. Through nutritional risk screening and assessment,it can be used to provide reference for assessing the nutri-tional risk,the nutritional support and the effect of nutritional support on prognosis of children with sepsis.At present,there are few studies on the nutritional risk and nutritional support in children with sepsis.In this arti-cle,we reviewed the research progress on nutritional risk and nutritional support in children with sepsis.

Biliary tract infection is the most commonly seen severe complication of malignant obstructive jaundice (MOJ)with a high mortality rate. Bile bacterial infection in MOJ patients is related with a variety of clinical factors and the therapeutic approaches including surgical operation,ERCP and percutaneous transhepatic cholangial drainage( PTCD). Bile bacterial culture combined with drug sensitivity test is of great importance for selection of optimal antibacterial agents. In this article,the related factors,current status of therapeutics,biliary bacterial spectrum and drug sensitivity in MOJ with biliary tract infection were reviewed for defining the clinical indicators and guiding the use of antibacterial agents.

Objective To build occupational management skills training mode for the community patients with psychosis in recovery stage by using action research method. Methods Action research method was applied to mental rehabilitation patients in Sunshine Psychiatric Garden of Shanghai to manage vocational rehabilitation support. By literature verification and empirical experience, the key problems were found out, and goals were established. Then management skills according to planning, action, observation, reflection and correction were implemented. This circle were spiraled for 2-3 times stages, and verification and evaluation before and after action practice based on Negative Symptom Rating scale (SANS) and Social Disability Screening Scale (SDSS). Results The community mental vocational rehabilitation was built with action research and based on the evidence of foreign psychic rehabilitation supportive individual placement and support. The mode should consider the professional characteristics of technical, social and economic. Also, it should contain professional ability, social skills and job adaptability training and performance evaluation, and offer salary allowance. The factors of SANS in 21 patients after practice were significantly improved (P < 0.01), and most of the factors in the SDSS were significantly improved (P < 0.01). Conclusions Community psychic vocational rehabilitation using action research method is a kind of advanced nursing practice, and also a process of evidence-based practice, which can provide a systematic, specific, practical work method for community mental rehabilitation institutions to force vocational rehabilitation training.

The effects of monoterpene perilly alcohol (POH) alone or in combination with STI571 on the proliferation and apoptosis of the cell line K562 positive for Bcr/Abl were investigated. By using cell culture, the effect of the drugs on the proliferation of the cells was studied. TUNEL and flow cytometry assay of FITC-Annexin V and PI labeled cells were applied to detect the effects of the drugs on the apoptosis of the cells. The results showed that at 36 h, IC50 of POH on K562 positive for Bcr/Abl and HL-60 negative for Bcr/Abl were 81.0 +/- 11.3 micromol/L and 113.6 +/- 23.4 micromol/L respectively (P>0.05). POH could inhibit the proliferation of K562 in a time- and dose-dependent manner with the inhibitory rate of 100 micromol/L POH on K562 cells at 36 h being (53.2 +/- 3.65)%. K562 cells were more sensitive to STI571 than POH. IC50 of STI571 on K562 cells in 36 h was (0.256 +/- 0.054) micromol/L. In a time- and dose-dependent manner, POH induced the apoptosis of K562 cells with the percentage of apoptotic cells by 100 micromol/L POH at 40 h being (21.0 +/- 3.3)%. Both 100 micromo/L POH and 0.2 micromol/L STI571 had the same inhibitory effects on the K562 cells at 36 h. But at 12 and 24 h, the inhibitory rate of POH was significantly higher than that of STI571 (P<0.05) and the ability of STI571 inducing apoptosis at 36 h was greater than that of POH. 50 micromol/L, 100 micromol/L and 200 micromol/L POH in combination with 0.2 micromol/L STI571 could obviously increase the inhibitory effects on the cellular proliferation. Combined use of 50 micromol/L, 100 micromol/L, 200 micromol/L with 0.2 micromol/L STI571 could strongly induced apoptosis, especially 200 micromol/L POH in combination with 0.2 micromol/L STI571. It was concluded that the antileukemia effect of POH had no obvious Bcr/Abl positive selectivity. POH can inhibit the proliferation of K562 and induce the apoptosis in a time- and dose-dependent manner. K562 cells were more sensitive to STI571 than POH. POH in combination with STI571 could obviously enhance the abilities of STI571 inhibiting the proliferation and inducing apoptosis of K562 cells.
