Objective To investigate the influence factors of malnutrition risk in hospitalized children,in order to provide theoretical basis for early identifying hospitalized children at the risk of malnutrition and for guiding clinical nutritional intervention.Methods Hospitalized children in the Department of Pediatrics of our hospital from March 1st 2013 to April 30th 2014 were included and assessed using Screening Tool for the Assessment of Malnutrition in Pediatrics (STAMP).Questionnaire survey was conducted and clinical data was recorded.The children were divided into two groups according to STAMP scores upon admission,namely high malnutrition risk group and low malnutrition risk group.Comparing the differences of basic characteristics,laboratory examinations,and treatments between the two groups,associated factors of statistical significance were detected.With the associated factors identified in single factor analysis as independent variables and STAMP score-based group division as the dependent variable,multifactor unconditional Logistic regression analysis was performed to explore the independent risk factors influencing STAMP scores of hospitalized children.Results A total of 1 406 hospitalized children were included,of whom 738 were at high malnutrition risk,and the other 668 were at low malnutrition risk.Single factor analysis indicated that fever before admission (Z =-3.809,P =0.000),severity of condition (x2 =14.068,P =0.000),age (x2 =5.813,P =0.017),and length of fever before admission (t =2.793,P =0.005) were associated with high malnutrition risk of hospitalized children.Non-conditional Logistic regression suggested that severity of condition (OR =1.557,95％ CI:1.164-2.083,P =0.003),length of fever before admission (OR =1.039,95％ CI:1.011-1.068,P =0.006),and granulocyte count (OR =1.032,95％ CI:1.004-1.061,P =0.027) were risk factors of high malnutrition risk in hospitalized children,and age (OR =0.942,95％ CI:0.909-0.977,P =0.001) was protective factor.Conclusion Age,severity of condition,length of fever before admission,and granulocyte count can provide helpful information for early identification of hospitalized children at high malnutrition risk.

Objective To compare the immunoregulatory role of polysaccharides from Rhizoma Dioscoreae and Rhizoma Dioscoreae Preparata in mice with immunosuppression. Methods Carbon clearance test and hemolysin test were used to evaluate the non-specific and specific immunoregulatory roles of polysaccharides from Rhizoma Dioscoreae and Rhizoma Dioscoreae Preparata by different extraction methods..Result The polysaccharides extracted with cold water from Rhizoma Dioscoreae Preparata had a stronger effect than Rhizoma Dioscoreae on increasing the index of K and enhancing phagocytic function of mononuclear-macrophage and hemolysin level. Conclusion The polysaccharides extracted with cold water from Rhizoma Dioscoreae Preparata have a stronger effect in improving the cellular and humoral immune function than Rhizoma Dioscoreae, which accords with the clinical application and will lay a foundation for further explaining the processing mechanism of Rhizoma Dioscoreae Preparata.

Objective To investigate the difference of serum prealbumin in hospitalized children and its value in Screening Tool for the Assessment of Malnutrition in Pediatrics ( STAMP) in hospital-izedchildren.Methods 867hospitalizedchildrenwererecruitedfromMarch2013toApril2014in the First Affiliated Hospital of Fujian Medical University .All the patients were assessed using STAMP and collected venous blood sample for measuring serum prealbumin within 24 hours after admission.All the patients were surveyed for information regarding gender , age, dietary changes, etc.and their clini-cal data and laboratory results during hospitalization collected .The patients were divided into high mal-nutrition risk group ( HMRG) and low malnutrition risk group ( LMRG) according to STAMP scores upon admission. Results There were 463 children ( 53.4%) in HMRG, and 404 in LMRG (46.6%).Compared with the LMRG, the HMRG had significantly lower serum prealbumin [ (144.7 ± 50.6) mg/L vs.(173.6 ±71.3) mg/L, t=6.795, P=0.000].After controlling for age, course of disease, white blood cell count, albumin, glutamic-oxalacetic transaminase, C-reactive protein in covariance analysis, the HMRG still had significantly lower serum prealbumin than the LMRG [ estimate ( 95% CI): 139.8 ( 134.9 -144.8 ) mg/L vs.157.9 ( 151.9 -163.8 ) mg/L, F =20.433 , P=0.000 ) .Clinical cure rates in HMRG with low serum prealbumin , HMRG with normal serum pre-albumin, LMRG with low serum prealbumin, and LMRG with normal serum prealbumin were 62.9%(95/151), 80.5% (251/312), 77.1% (27/35), and 98.1% (362/369) (χ2 =112.80, P=0.000 ) , respectively; incidences of hospital acquired infection were 21.9% ( 33/151 ) , 8.7%( 27/312 ) , 22.9% ( 8/35 ) , and 1.9% ( 7/369 ) (χ2 =63.55 , P =0.000 ) , respectively. Conclusion High malnutrtion could be distinguished more accurately using the combination of the as-sessment of malnutrition screening tools and serum prealbumin measurement .

Objective To investigate the effect of electroacupuncture at Shenting (DU24) and Baihui (DU20) on learning and memory ability, as well as the nerve cell and the expression of mRNA of Bcl-2 and Bax in the hippocampus of rats with cerebral ischemia/reperfusion (I/R) injury. Methods 45 male Sprague-Dawley rats were randomly diveded into sham group (n=15), control group (n=15) and electroacupuncture group (n=15). The latter 2 groups were modeled with middle cerebral artery occlusion for 2 h and reperfusion. The electroacupuncture group received electroacupuncture at Shenting and Baihui for 7 days. They were tested with Morris water maze, and then, their hippocampus was observed under Nissl staining and the level of Bcl-2 and Bax mRNA were determined with RT-PCR. Results The escape latency decreased (P<0.001) and the frequence the platform was crossed increased (P=0.001) in the electroacupuncture group compared with the model group, with less damage of the nerve cell and the expression of Bax mRNA, and more of Bcl-2 mRNA (P<0.05). Conclusion Electroacupuncture can prevent learning and memory ability from cerebral ischemia/reperfusion injury in rats, which may associate with adjustment of expression of apoptosis-related gene to inhibit apoptosis of nerve cell.

Osteomyelitis (OM) is still a major problem for orthopedists. Numerous studies have shown that genetic factors may play an important role in the pathogenesis of OM. As a third generation genetic marker, single nucleotide polymorphisms (SNPs) have received increasing attention from scholars who are studying genetic susceptibility to OM. In-depth research on the SNPs of susceptibility genes will help to explore new strategies for prevention, diagnosis and treatment of OM. This article reviews the research advances concerning gene SNPs and OM susceptibility.
