Objective To explore effect of probiotics on improving the feeding intolerance in very low birth weight infants(VLBWI). Methods Sixty cases of VLBWI were randomly divided into two groups, 30 infants as therapy group,another 30 infants as control group.All infants in two groups were given aggressive intravenous nutrition and enteral feeding with preterm formulars. At the same time, probiotics were administered combined with preterm formulars to infants in therapy group. Milk amount, gastric residual, initial time of enteral feeding, time required for full enteral feeding and body weight on day 21 after birth were all recorded.Results Rate of no gastric residual increased significantly in therapy group compared with that of control group(t=6.24 P

OBJECTIVE:To establish a method for the content determination of L-epicatechin in Actinidiae arguta. METHODS:HPLC was performed on the column of Kromasil C18 with mobile phase of acetonitrile-0.2%Acetic acid solution(15:85,V/V)at a flow rate of 1.0 ml/min,detection wavelength was 210 nm,column temperature was 25 ℃,and the volume injection was 10 μl. RESULTS:The linear range of L-epicatechin was 10.47-167.52 μg/ml(r=0.999 9);RSDs of precision,stability and reproducibility tests were lower than 2%;average recovery was 98.07%-101.71%(RSD=1.39%,n=6). CONCLUSIONS:The method is simple, accurate and reliable,and suitable for the content determination of L-epicatechin in A. arguta.

Population pharmacokinetics of vancomycin (VAN) in the Chinese patients was described by using nonlinear mixed-effects modeling (NONMEM). 619 VAN serum concentrations data from 260 patients including 177 males and 83 females were collected separately from two centers. A one-compartment model was used to describe this sparse data. No significant difference was observed between two center datasets by introducing SID covariate. The final model was as CL= (θ (base0+ θ(max) x(1 -e(-θ(Age)(Age/72) and V = θ x θ (Age)(Age/72). The creatinine clearance (CL(Cr)) and Age were identified as the most significant covariate in the final model. Typical values of clearance (CL) and volume of distribution (V) in the final model were 2.91 L x h(-1) and 54.76 L, respectively. Internal model validation by Bootstrap and NPDE were performed to evaluate the robustness and prediction of the final model. The median and 95% confidence intervals for the final model parameters were based on 1000 Bootstraps. External model evaluation was conducted using an independent dataset that consisted of 34 patients to predict model performance. Pharmacodynamic assessment for VAN by AUC (0-24 h) to MIC ratios of over 400 was considered to be the best to predict treatment outcomes for patients. AUC (0-24 h) was calculated by clearance based on the above population model. The results indicate that the conventional dosing regimen probably being suboptimal concentrations in aged patients. The approach via population pharmacokinetic of VAN combined with the relationship of MIC, Age, CL(Cr) and AUC(0-24 h)/MIC can predict the rational dose for attaining efficacy.

Objective To explore the composition principles of prescriptions for simple obesity based on the analysis of medical literature issued in recently 30 years about Chinese medicine for simple obesity. Methods We collected literature of Chinese medicine in treating simple obesity from VIP, CNKI, Wanfang, CBM and CMCC/CMCI databases, and screened out the formulas for simple obesity to establish a formula database. And then the medication rules were figured out with the Traditional Chinese medicine Inheritance Support System version 2.5 (TCMISS 2.5) software. Results A total of 57 formulas were screened out. And the top 10 herbs with highest occurrence frequency in the prescriptions were Poria, Rhizoma Atractylodis Macrocephalae, Rhizoma Alismatis, Radix et Rhizoma Rhei, Fructus Crataegi, Radix Astragali, Radix Glycyrrhizae, Folium Nelumbinis, Pericarpium Citri Reticulatae and Semen Cassiae. After data mining, we got 13 high-frequency herb-pair combinations and 31 core combinations, and 8 new prescriptions were extracted. Conclusion The research has achieved the quantitative description of the relationship between the Chinese medicines, the extraction of the core combinations and the discovery of new Chinese medicine prescriptions for simple obesity. The results will provide references for the development of new Chinese medicines for the treatment of simple obesity .

Spinal biomechanics, especially the range of spine motion,has close connection with spinal surgery. The change of the range of motion (ROM) is an important indicator of diseases and injuries of spine, and the essential evaluating standards of effect of surgeries and therapies to spine. The analysis of ROM can be dated to the time of the invention of X-ray and even that before it. With the development of science and technology as well as the optimization of various types of calculation methods, diverse measuring methods have emerged, from imaging methods to non-imaging methods, from two-dimensional to three-dimensional, from measuring directly on the X-ray films to calculating automatically by computer. Analysis of ROM has made great progress, but there are some older methods cannot meet the needs of the times and disappear, some classical methods such as X-ray still have vitality. Combining different methods, three dimensions and more vivo spine research are the trend of analysis of ROM. And more and more researchers began to focus on vivo spine research. In this paper, the advantages and disadvantages of the methods utilized recently are presented through viewing recent literatures, providing reference and help for the movement analysis of spine.

Objective To explore cost of standard operation procedure of primary public healthcare services.Methods Standard operation procedure of primary public healthcare services was put forward according to national basic public healthcare service standards (2011 edition) in 2012.Random sampling method was used to choose participants from two community sanitary service centers,two township heahhcare centers and one maternity and child heahhcare hospital.Service standard operation procedure was used to measure human cost and supportive cost of public healthcare services.Results Management of 10 thousand patients who had different diseases needed various numbers of medical staff (MS),such as health profile needed 3.4 MS,hypertension management needed 10.8 MS,diabetes management needed 10.6 MS,elderly people care needed 9.2 MS,child care needed 4.6 MS,maternal care needed 24.3 MS,psychosis management needed 13.3 MS,and planned immunity for children needed 4.6 MS.Besides,the people whole covered service projects need 2.4 MS per 100 thousand people.The research showed that managing 1 sample of different kind people needed different human cost,such as health profile needed 22.67 yuan,hypertension management needed 72.69 yuan,planned immunity for children needed 30.68 yuan,diabetes management needed 71.34 yuan,old people management needed 61.50 yuan,child care needed 30.88 yuan,maternal care needed 157.15 yuan,psychosis management needed 74.25 yuan.Besides,the people whole covered service projects needed 124.9 thousand yuan per 100 thousand people.Conclusion For primary public healthcare service project,it should be critical to modify manning regulation and labor costs.
