Objective To determine the dietary nutritional status of rural residents in Midwestern Shandong Province,in order to improve the dietary pattern and health status of them.Method 11 987 residents,from 10 273 households,were included in this study by multi-stage randomized cluster sampling in 8 counties located in Midwestern Shandong Province.Questionnaire of Food Frequency (QFF) was applied to collect the information about the amount and frequency of food consumed by the subjects in the past year.Results The average intake of cereal,vegetable,fruit,meat,egg,milk,bean,oil and salt per reference man per day was 553.9 g,310.6 g,58.2 g, 36.3 g,50.1 g,16.7 g,34.4 g,44.8 g and 12.3 g,respectively.The average intake of energy,carbohydrate,protein,fat and dietary fiber per reference man per day was 12 095.6 kJ,451.8 g,85.6 g,78.8 g and 18.7 g as well Cereal food provides 66.1% of total energy; however,the meat provides only 6.6% of that.Carbohydrate,protein and fat amount to around 63.2%,12.0% and 24.8% of total energy, respectively.24.0% of fat intake was from animal food,while 76% of that was from vegetable food.Conclusions The intake of energy, protein,fat was sufficient for these subjects;however,the intake of vegetable,fruit,bean and meat was lower than the dietary reference intake.Moreover,oil and salt intake in these subjects was much higher than Chinese Recommended Nutrient Intakes.Thus,the amelioration of dietary pattern in rural residents will be an important task for nutrition workers in rural area of Midwestern part of Shandong Province in the future.

Objective:To evaluate the immunogenicity of recombinant factor H binding protein(fHBP) by detecting serum antibody titer and serum bactericidal antibody test (SBA).Methods:fHBP sequence was selected and synthesized, connected to plasmid pET43.1a, transformed to Escherichia coli BL21(DE3), and expressed two recombinant fHBP proteins, included two subfamilies, fHBPA and fHBPB. After purification, the recombinant fHBP proteins were immunized to rabbits and mice. The immune antiserum titer and the bactericidal titer to epidemic strains of meningococcal bacteria group B were measured by ELISA and SBA respectively. Results:The antiserum titer of fHBP immunized rabbits was greater than 2.0×10 6, and that of immunized mice was not less than 1.0×10 6. fHBP immunized rabbit serum had bactericidal titer more than 1∶128 to 41 strains A subfamily and 20 strains B subfamily in the SBA against 69 endemic strains, and there was no cross-protection between the subfamily bacteria. The bactericidal titers of mouse serum immunized fHBPA to strains A subfamily such as Nm210902 Nm211009、Nm450522 were 1∶1 024, 1∶608、1∶861, to Nm510703、Nm311304、Nm431002 were 1∶234、1∶861、1∶430 respectively, and mouse serum immunized fHBP B to strains B subfamily Nm311302、Nm311304、Nm431002 were 1∶876、1∶274、1∶1858, all of three strains were positive in bactericidal titers. Conclusions:the titer of fHBP antiserum was higher than 1.0×10 6, the bactericidal titer was no less than 1∶128 to 61 epidemic strains, and it has a 94.2% protective effect on 69 meningococcal epidemic strains group B.

Objective To-identify the factors associated with radiation-induced liver disease (RILD) and to describe the probability of RILD using the Lyman normal tissue complication(NTCP) model for primary liver carcinoma(PLC) treated with hypofractionated conformal therapy (CRT).Methods A total of 109 PLC patients treated with hypofractionated CRT were prospectively followed according to the Child-Pugh classification for liver cirrhosis,93 patients in class A and 16 in class B.The mean dose of radi- ation to the isocenter was (53.5?5.5) Gy,fractions of (4.8?0.5) Gy,with interfraction interval of 48 hours and irradiation 3 times per week.Maximal likelihood analysis yielded the best estimates of parameters of the Lyman NTCP model for all patients;Child-Pugh A and Child-Pugh B patients,respectively.Results Of all the patients,17 developed RILD (17/109),8 in Child-Pugh A(8/93 ) and 9 in Child-Pugh B(9/ 16).By multivariate analysis,only the Child-Pugh Grade of liver cirrhosis was the independent factor (P= 0.000) associated with the developing of RILD.The best estimates of the NTCP parameters for all 109 pa- tients were n=1.1,m=0.35 and TD_(50) (1)=38.5 Gy.The n,m,TD_(50) (1) estimated from patients with Child-Pugh A was 1.1,0.28,40.5 Gy,respectively,compared with 0.7,0.43,23 Gy respectively,for patients with Child-Pugh B.Conclusions Primary liver cancer patients who possess Child-Pugh B cirrho- sis would present a significantly greater susceptibility to RILD after hypofractionated CRT than patients with Child-Pugh A cirrhosis.The predominant risk factor for developing RILD is the severity of hepatic cirrhosis in the liver of PLC patients.

Objective To investigate the frequency of CD4~+CD25~+FOXP3~+Treg cells in the peripheral blood of systemic lupus erythematosus(SLE)patients and its association with disease activity.Methods Pe- ripheral blood mononuclear cells(PBMC)from 28 patients(including 18 active SLE)and 22 healthy controls were counted and stained for CD4,CD25 and intracellular FOXP3.Cells were examined by 3-color staining on the Epics XL-MC and data were analyzed using EXPO32 software.Disease activity was assessed by systemic lupus erythematousus activity index(SLEDAI).Results The frequency of CD4~+CD25~+FOXP3~+Treg cells was significantly decreased in patients with active SLE compared with patients with inactive SEE and controls [(1.08?0.43)%,(1.58?0.45)% and(1.66?0.34)%,P

UNLABELLED: Abstract: OBJECTIVE: To investigate the bacterial succession on rat carcasses and to evaluate the use of bacterial succession for postmortem interval (PMI) estimation. METHODS: Adult female SD rat remains were placed in carton boxes. The bacterial colonization of circumocular skin, mouth and vagina was collected to be identified using culture-dependent biochemical methods. The changes in community composition were regularly documented. RESULTS: The bacterial succession in three habitats showed that Staphylococcus and Neisseria were predominated in early PMI, especially Staphylococcus aureus and Neisseria lactamica in 6 hours after death. Lactobacillus casei developed on the 3-4 days regularly, and kept stable at a certain level in late PMI. CONCLUSION The involvement of normal and putrefactive bacteria in three body habitats of rat remains can be used for PMI estimation.

AIMTo assess the psychometric properties of the Chinese Index of Premature Ejaculation (CIPE).

METHODSThe sexual function of 167 patients with and 114 normal controls without premature ejaculation (PE) were evaluated with CIPE. All subjects were married and had regular sexual activity. The CIPE has 10 questions, focusing on libido, erectile function, ejaculatory latency, sexual satisfaction and difficulty in delaying ejaculation, self-confidence and depression. Each question was responded to on a 5 point Likert-type scale. The individual question score and the total scale score were analyzed between the two groups.

RESULTSThere were no significant differences between the age, duration of marriage and educational level (P> 0.05) of patients with and without PE and normal controls. The mean latency of patients with PE and normal controls were 1.6 +/- 1.2 and 10.2 +/- 9.5 minutes, respectively. Significant differences between patients with (26.7 +/- 4.6) PE and normal controls (41.9 +/- 4.0) were observed on the total score of CIPE (P< 0.01). Using binary logistic regression analysis, PE was significantly related to five questions of the original measure. They are the so-called the CIPE-5 and include: ejaculatory latency, sexual satisfaction of patients and sexual partner, difficulty in delaying ejaculation, anxiety and depression. Receiver Operating Characteristic (ROC) curve analysis of CIPE-5 questionnaire indicated that the sensitivity and specificity of CIPE were 97.60 % and 94.74 %, respectively. Employing the total score of CIPE-5, patients with PE could be divided into three groups: mild (>15 point) 19.8 %, moderate (10-14 point) 62.8 % and severe (< 9 point) 16.7 %.

CONCLUSIONThe CIPE-5 is a useful method for the evaluation of sexual function of patients with PE and can be used as a clinical endpoint for clinical trials studying the efficacy of pharmacological intervention.
