Objective To observe the acute pain service for analgesia effect and complications of postopera-tive analgesia and satisfaction after cesarean section.Methods 360 patients undergoing cesarean section and postop-erative continue analgesia were randomly divided into two groups.The control group (group C,n =178)was given with routine postoperative self -control analgesia give guidance.In the observation group (group A,n =182),a group for acute pain was founded,and the patients were explained about PCA self -control analgesia related knowledge before operation,together with the APS analgesia group people,the patients were given with postoperative pain management,observed self -control analgesia efficacy and side effects,and gives the corresponding treatment and guidance.The difference of analgesia incomplete and complication were observed such as nausea and vomiting,calm, itchy skin.Questionnaires that postoperative analgesia satisfaction survey were filled inafter discharged.The satisfac-tion of nurse with the APS were observed.Results Postoperative analgesia complication in group A were significantly lower than that in group C(P <0.01,P <0.05),APS analgesic incomplete in group C was significantly higher than groupA (χ2 =11,P <0.01).The satisfaction of PCA in group A were significantly higher than group C (P <0.01, P <0.05),ward nurses job satisfaction also increased significantly (t =2.63,P <0.05).Conclusion Acute pain service effectively improve analgesic quality and reduce related complications after cesarean section increase patients postoperative analgesia satisfaction,increase the ward nurses job satisfaction.

0.05); serum HBsAb levels of pregnant mice and neonatal mice in group with CpG-1826 (20 ?g)+hepatitis B vaccine significantly higher than those in group with CpG-1826 (10 ?g, 40 ?g)+ hepatitis B vaccine,hepatitis B vaccine and control respectively(P0.05).Conclusions Combination injection of CpG-1826 20 ?g and hepatitis B vaccine can markedly increase serum antibody levels of pregnant mice and neonatal mice, but don′t affect the survival quantity, the growth and development of neonatal mice.CpG-1826 is an ideal immune adjuvant for neonates with immature immune system during pregnancy.

?ig-h_3 was first identified as a transforming growth factor-beta1-inducible gene in human lung adenocarcinoma cell line. It encodes for a secreted extracellular matrix (ECM) protein, which is thought to act on cell attachment and ECM composition. Previous study showed that ?ig-h_3 were highly expressed in human hepatoma cell lines and lowly expressed in human normal hepatic cells. The present study aimed to transfect ?ig-h_3 into 7721 cells to investigate its effect on secretion of MMPs in the transfected human hepatoma cells. Full-length ?ig-h_3 gene,cloned by reverse transcription polymerase chain reaction (RT-PCR) was inserted into the eukaryotic expression vector pEGFP-C_2. The recombinant plasmid was transfected into 7721 cells with Lipofectamine2000 and Gelatin-Zymography were adopted to detect the production of MMPs in the transfected cells. Results showed that ?ig-h_3/pEGFP-C_2 recombinant expression plasmid was successfully constructed and achieved high transfection efficiency. MMPs expression of the transfected cells was promoted significantly. These results suggest that overexpression of ?ig-h_3 promoted the production of MMPs, indicating that ?ig-h_3 may play roles in the invasive and metastatic processes of hepatoma.

CoQ10 has been used not only as a medicine but also as food supplements because of its various physiological and biochemical activities. A full-factorial central composite design and response surface methodology were used for optimizing three precursors Solanesol, 4-hydroxybenzoic acid and methionine to maximize the production of CoQ10 by Rhodopseudomonas palustris J001. The optimization of the model predicted a maximum response 40.6 [(mg CoQ10)(g dried biomass)-1] CoQ10 production with 124.8 mg l-1 Solanesol, 267.7 mg l-14-hydroxybenzoic acid and 130.2 mg l-1 methionine, respectively. A new combination was prepared according to the result. The observed response was 40.5 ± 0.2 [(mg CoQ10)(g dried biomass)-1] and was 109.8%higher than in the control with no addition of the three precursors.

Objective:To identify the characteristics and risk factors of the refractures after percuta-neous kyphoplasty ( PKP) and percutaneous vertebroplasty ( PVP) .Methods:A retrospective analysis of 148 patients who had undergone PKP or PVP between March 2006 and October 2013 inPeking University People’ s Hospital was conducted.In the study, 29 patients with 42 refractured vertebra and 119 patients without refracture were included.All the patients were observed for a time of (34.4 ±26.8) months. Clinical, imaging and procedure related factors ( gender, age, height, weight, body mass index, the level of the injured vertebra, the time interval between the procedure and the refracture, the level of the refractured vertebra, the bone cement volume injected, performed PKP or PVP,performed unilateral or bilateral, the percentage of anterior vertebral height restoration, the correction of the Cobb angle, cement diffusion, bone mineral density, presence or absence of diabetes mellitus, history of fractures of the whole body, anti-osteoporosis treatment, cement leakage) for each group were analyzed by Cox propor-tional hazards regression analysis.Results:Of all the patients,16 (55.17%, 16/29) had refractures in the adjacent vertebra, and 13 (44.83%, 13/29) had refractures in the nonadjacent vertebra.Refrac-tures within 3 months accounted for 31.03%(9/29) of all the refractures, and within 1 year accounted for 55.17%(16/29).Both older age (P=0.027, HR=1.051, 95%CI=1.006-1.098) and a his-tory of fractures of the whole body (P=0.012, HR=0.386, 95%CI=0.184-0.812) were statistical-ly significant as the independent risk factors for predicting refractures.Others were not associated with re-fractures ( P>0.05) .Conclusion:Older age and a history of fractures of the whole body are the inde-pendent risk factors of the refractures after PKP and PVP.The mechanism of the refractures after PKP and PVP is mainly the natural development of osteoporosis.

Objective:To study the association between non-syndrome cleft lip and palate (NSCL/P)and MAFB (rs6072081, rs6065259,rs17820943,rs11696257)gene polymorphism in NingXia Hui and Han population.Methods:512 cases of NSCL/P,258 case of Hui nationality and 254 of Han,174 cases of complete 3 core family members(patients and their parents),142 cases of single parents families(patients and their single parents),were collected in patient group.505 cases of healthy newborns were collected in control group.The MAFB gene SNPs were determined with TaqMan SNPs genotyping methods and the data were analyzed by case-con-trol analysis,transmission disequilibrium test(TDT)and family based association test(FBAT).Results:Case-control analysis found that,there was a statistical significance of the genotypes and allele frequency between patients and the controls in MAFB of the 4 locus (P <0.05);but all of the 4 locus showed no difference in patients with cleft palate(P >0.05).Conclusion:The 4 locus single nucle-otide polymorphism was associated with NSCL/P in Ningxia population.

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 perform a molecular epideminlogical investigation on the types of Leptospira interrogans isolates from leptospirosis patients and animal hosts in Jiangxi province,using a pulsed-field gel electrophoresis (PFGE).Methods The extracted chromosomal DNA from leptospiral isolates were digested with restriction endonuclease Not Ⅰ and the DNA segments were separated by using PFGE.By BiOnurerics V4.0 software and 75% similarity as the standard,the obtained PFGE images from leptospiral isolates were managed to establish a digitization database and then the PFGE maps of leptospiral isolates were compared with those of reference standard strains belonging to 15 serovars in 15 serogroups of L.interrogans,for cluster analysis.Results 139 strains of L.interrogans isolated from different areas of Jiangxi province were classified into 46 PFGE types.Among the PFGE types,LepNot Ⅰ.0071,LepNotⅠ.0072 and LepNot Ⅰ .0043 were the predominant types that accounting for 28.06%,15.11% and 7.19% of all the leptospiral isolates,respectively.The PFGE maps from 84.89% (118/139) of the 139 leptospiral isolates were found to basically match those of 6 reference standard strains belonging to 6 serovar in 6 serogroups of L.interrogans.In the 118 matched ieptospiral isolates,32.37% (45 strains),15.83% (22 strains) and 15.11% (21 strains)belonged to sero-groups Icterohaemorrhagiae serovar Lai,sero-groups Australis serovar Australis and sero-group Javanica serovar Javanica,respectively.Conclusion PFGE seemed a fast,accurate and effective method for typing of L.interrogans isolates.Serogroup Icterohaemorrhagiae serovar Lai and followed by serogroup Australis serovar Australis as well as serogroup Javanica serovar Javanica were the predominant L.interrogans species in humans and animal hosts in Jiangxi province.

OBJECTIVETo analyse the levels of polychlorinated dibenzo-p-dioxins and dibenzo-furans (PCDD/Fs) in sea fish samples in some sea area in China surveyed by using isotope dilution HRGC/HRMS and was evaluated the local people with PCDD/Fs exposure from eating fish.

METHODSSeven different kinds of fish and twenty fishes were sampled totally. Dibenzo-p-dioxins and dibenzo-furans were extracted from fish samples by Soxhlet extraction, concentrated and purified by FMS column chromatograph and enriched by carbon column. Confirmation and quantitative analysis at ng/kg level of PCDD/Fs was performed by HRGC/HRMS using multiple ion detection mode (MID).

RESULTSCarp-2 was the certified reference material obtained from the NRC Institute of Canada. The concentration of 9 compounds was consistent with the certified value, and precision was evaluated in this study. The relative standard deviation was less than 15 percent for three times determination. The average concentration of 20 sea fishes was 1.48 ng/kg wet weight, the range was in 0.21-8.10 ng/kg wet weight, and the average total toxicity equivalency factor (TEQ) was 0.292 ng TEQ/kg (wet weight basis) and the range was 0.030-1.291 ng TEQ/kg for these 20 fishes. The evaluation exposure from fish for local people was 0.58 pg WHO-TEQ/kg BW.day.

CONCLUSIONThe levels of PCDD/Fs was different from sample to sample, and the exposure from fish be less than WHO tolerance limit standard, however, the status for PCDD/Fs pollution should not be ignored especially when having an intake of multi-food.

The newly developed approach of tissue engineering has been shown to be great potential on the ligament reconstruction, however, the criterion for the scaffolding material was strict. The scaffold material must have enough strength as well as elasticity, at the same time, it should be biocompatible. As a nature protein, silk is a promising tissue engineering scaffold material for its excellent mechanical property. However, because of the contamination of sericin, the chief problem of silk's medical use is degumming. We compared three degumming reagents to choose the one which has least effect on the mechanical property of silk, and then the best degumming condition was confirmed: 0.4%NazCO3, 90 degrees C, 1 h. Rat bone morrw mesenchymal stem cells (rMSCs) were seeded on the fibroin, and scanning electron microscope (SEM) and fluorescence microscope were used to detect the biocompatibility of it. And the results showed that fibroin had outstanding biocompatibility and cell affinity, which indicated the further use of fibroin in tissue engineering.
