Objective To investigate whether the effect of rabeprazole in treating gastroesophageal reflux disease is related to CYP2C19 gene polymorphisms.Methods 278 patients with gastroesophageal reflux disease confirmed by endoscopy and proton-pump inhibitor testing were enrolled in this study,including non erosive reflux disease (NERD) in 122 cases,the reflux esophagitis (RE) in 98 cases and Barrett esophagus in 58 cases.They were treated with rabeprazole for 8 weeks.GerdQ scores before and after the treatment were completed,endoscopy was performed again in patients with RE after treatment.The blood CYP2C19 genotyping was detected by matrix assisted laser desorption ionization time of flight mass spectrum(MALDI-TOF-MS).Results According to the genotype of CYP2C19,they were divided into extensive metabolizers,intermediate metabolizers and poor metabolizers,accounted for 39.57%,42.45% and 17.98%,respectively.There was no significant difference in GerdQ scores of three groups before treatment,and also had no significant difference after 8 weeks treatment,but in each subgroup GerdQ scores after treatment was decreased significantly than before treatment.The total effective rate of 98 patients with RE by endoscopy was 86.73%,but there was no significant difference in total effective rate of the three groups after treatment.Conclusion Rabeprazole is effective in the treatment of gastroesophageal reflux disease.Moreover,rabeprazole is less affected by CYP2C19 genotype and therefore its curative effect is more stable.

With more and more attention and investment on acupuncture scientific researches, considerable outcomes and achievements has been acquired, but the shortcoming of low transformation rate of acupuncture research achievements is gradually exposed. Nowadays there is no related report on this problem, so based on achievement translational research in other areas and practical situation of acupuncture, the existing problems and solutions are analyzed. As a result, the existing problems include (1) the research content is mainly basic research and clinical research but less acupuncture device research, leading to limited transformation efficiency; (2) the evaluation system and transformation pattern are still needed to be perfect. The solutions are (1) to properly evaluate the research achievements of acupuncture, (2) to advocate the concept and method of translational medicine, (3) to reform the policy and system, and (4) to establish valid platforms covering research, outcomes and transformation.

Objective To explore the clinical characteristics,management and pregnancy outcome in patients with ovarian tumor and ovarian tumor like condition complicated with pregnancy.Methods The clinical data of 248 patients with ovarian tumor and ovarian tumor like condition eomplicated with pregnancy who treated,operated and pathology conducted from January 2003 to December 2009 was analyzed retrospectively.Results Among of 248 patients,8 patients were found by pelrioscopy,184 patients were found by sonography.The rate of ovarian tumor and ovarian tumor like condition during pregnancy was 0.49％ (248/50 652),about 52.82％(131/248)were diagnosed as benign tumor,most of them were ovarian mature teratoma(22.18％,55/248).About 45.56％(113/248)were diagnosed as ovarian tumor like condition,most of them were ovarian chocolatecyst(23.79％,59/248).Four patients(1.61％,4/248)were ovarian malignant tumor.Two hundred and sixteen received operation,term birth was in 164 patients,premature birth was in 19 patients,miscarriage was in 33 patients.Conclusions Pelvioscopy and sonogaraphy are principally important in the diagnosis and detection of ovarian tumor during pregnancy.Pregnancy complicated with ovarian tumor or ovarian tumor like condition should be treated by tumor resection.Suitable surgery intervention during second trimester is safe.

Objective To investigate the predictive value of the 40 Hz auditory steady state response (40-Hz ASSR) in the short-term prognosis of patients with brainstem stroke.Methods The 40-Hz ASSR and brainstem auditory evoked potentials (BAEP) examinations were recorded and graded from 36 patients with brainstem stroke admitted in the Neurological Intensive Care Unit (NICU). Tue end point of short-term prognostic evaluation was at the time of leaving the NICU. Tue patients with brainstem stroke were divided into the survival group (n =21) and the death group (including brain death,n = 15). The correlation between the grade of the 40-Hz ASSR or BAEP and the short-term prognosis was analyzed. Results The grade of the 40-Hz ASSR (r=0.571,P =0.000) or BAEP (r =0.441,P =0.001 ) was significantly correlated with the short-term prognosis in patients with brainstem stroke. The sensitivity,specificity and accuracy of the 40-Hz ASSR were 60.00％,100％ and 83.33％,respectively,and those for BAEP were 66. 67％,71.43％ and 69. 44％,respectively. Conclusions Tue 40-Hz ASSR has a certain short-term prognostic value in patients with brainstem stroke. The higher the grade of 40-Hz ASSR is,the more serious the illness,and the worse the prognosis.

Calcium phosphate cement (CPC) is considered as an important bone repairing materials due to its excellent biocompatibility, osteoconductivity and remodellability, the study about its performance is still a hot topic in the field of bone tissue engineering. Premixed calcium phosphate cements (PCPC) has advantages that can save operatiion time,be convenient to the operation and preservation compared with the traditional way of immediately mixing calcium phosphate cement. PCCP has overcome the shortcomings of uneven and inadequate mixing, and can be arbitrarily remodeled according to the shape of defect, thus researches on PCCP has also become more and more interested

Background contamination is a major problem in the analysis of organophosphate esters (OPEs). In this study, the possible sources of OPEs pollution were screened and several different ways were applied to minimize the blank contamination. Under the strict quality control measures, the cleanup efficiency of different solid phase extraction (SPE) was investigated for OPEs in different environmental matrices. A method was developed for the detection of 7 OPEs in dust, soil and sediment samples by gas chromatograph coupled with mass spectrometry ( GC / MS). Target compounds were extracted by hexane:dichloromethane (1 : 1, V/ V) followed by aminopropyl silica gel SPE column cleanup for dust, and target compounds in soil and sediment were Soxhlet extracted and cleanuped by two-step SPE. The results showed that the aminopropyl silica gel SPE column displayed the best purification performance among the three employed columns. Instrumental detection limits among the 7 OPEs ranged from 2. 5 to 25. 8 μg / L, and the method limits of quantification (MLOQs) in dust and soil sample ranged from 1. 4 to 15. 7 ng / g and 0. 3 to 2. 9 ng / g, respectively. The average recoveries of 7 OPEs in different matrices ( dust and soil) at two spiked concentration levels ranged from 67. 9% to 117. 4% . The proposed method was successfully applied to detect OPEs in different environmental matrices collected in Shanghai.
