Objective To investigate the influence factors of central venous catheter related infections (CVC-RI) in postoperative patients with gastric carcinoma treated with parenteral nutrition,in order to provide scientific basis for prevention and treatment.Methods Using the retrospective study method,150 patients who treated with parenteral nutrition after operation of gastric carcinoma from December 2013 to March 2014 were selected.Information including age,sex,anamnesis,catheter indwelling time,infusion rate of nutrient solution,and so on were collected.Patients with central venous catheter related infections were set as infection group,patients without infection as the control group,and the group logistic regression analysis was used to analyze the collected data.Results 21 patients in infection group had CVC-RI,and the incidence was 14.00％ (21/150),while 129 patients in control group had CVC-RI.Univariate analysis showed there was significant difference between infection group and control group in age,anamnesis,catheter indwelling time and infusion rate of nutrient solution (x2=17.126,5.447,12.795,7.973,P＜0.05),however there was no significant difference in sex,health insurance,the success rate of catheterization and whether glutamine was in nutrient solution (P＞0.05);the group logistic regression analysis showed that age (OR=15.927,95％CI 3.305-76.756,P＜0.05)and catheter indwelling time (OR=3.511,95％CI 1.028-11.992,P＜0.05) were independent risk factors for CVC-RI,however infusion rate of nutrient solution (OR=0.140,95％CI 0.033-0.597,P＜0.05) was a protective factor.Conclusions For the postoperative patients with gastric carcinoma treated with parenteral nutrition,CVC-RI is closely related to age,catheter indwelling time and infusion rate of nutrient solution.So reducing catheter indwelling time,restoring the enteral nutrition under condition permission as so on as possible can reduce infection of elderly patients.

This study was aimed to analyze compatibility rules of Chinese drugs and prescription design in the pre-vention and treatment of scleroderma. The database of scleroderma treated by Chinese medicine was set up. And then, association rules were used to analyze the prescription compatibility rules. The results showed the highest fre-quency of drugs in the treatment of scleroderma were Astragalus, Angelica sinensis and Salvia. The tonifying and re-plenishing medicinal, blood-activating and stasis-resolving medicinal and exterior-releasing medicinal were with the highest frequency. The commonly used formula in the treatment of scleroderma was Y ang-He decoction. For herbal groups, occurrence of the highest was the combinations of Ramulus Cinnamomi-Astragalus and Carthamus tinctorius L.-Astragalus. Three kinds of herbals were commonly coupled, such as Polygonum multiflorum Thunb. and Caulis Spatholobi with Salvia, P. multiflorum Thunb. and R. Cinnamomi with Salvia, P. multiflorum Thunb. and Astragalus with Salvia, prepared Radix Rehmanniae and Codonopsis with C. tinctorius L., prepared Radix Rehmanniae and Codonopsis with R. Cinnamomi, Codonopsis and Radix paeoniae rubra with R. Cinnamomi. Four kinds of herbals such as R. Cinnamomi, Glycyrrhiza uralensis Fisch., Astragalus and Codonopsis were commonly coupled. It was con-cluded that compatibility rules of Chinese medicine in the prevention and treatment of scleroderma laid the founda-tion for herbal medicine selection and prescription design.

Objective To verify the effectiveness of electrical impedance tomography (EIT) with multi-layer electrodes in gastric emptying measurement by simulation experiments using EIT with three-layer electrodes.Methods Firstly,EIT system with three-layer electrodes and gastric emptying measurement simulation equipment was designed and constructed to simulate gastric emptying process and obtain EIT reconstruction images.Secondly,the region where the electrical characteristic of gastric changes was selected as region of interest.Finally,the relative impedance change rate in region of interest for every image obtained from all three layers was consecutively recorded,then the gastric emptying curve was formed and gastric emptying time was calculated.Results There are obvious differences among the sharp of impedance change curves of interested region for three layers,and the gastric emptying time and process of each layer is also different from one another.It is suggested that the passing path and emptying manner of food in gastric emptying process reflected by EIT images varied from layer to layer.Therefore,the necessity and feasibility of using EIT with three-layer electrodes in gastric emptying measurement study is verified.Conclusions EIT with three-layer electrodes can provide more abundant information of gastric motility function associated with gastric emptying pathology and physiology state.It is likely to be a noninvasive,convenient and effective imaging method for the detection and evaluation research on gastric emptying and gastric motility.

According to the multi-information characteristic of pulse tracings in traditional Chinese medicine(TCM) and the dynamic analysis and identification technique of sonogram,the multi-information detection system of pulse examination was constructed by combining B-type ultrasound and flexible transducer.It made information integration of supersonic dynamic image,pressure pulse wave,photoelectric capacity pulse wave and electrocardiogram,and though the aggregate analysis of computer information processing technique,established the pulse tracings signature analysis method,formed optimized solving scheme for describing the four attributes("location,velocity,shape and potential") of pulse examination in TCM.From the multi-information data of healthy people's pulse tracings collected by this system,it can be infer that the new method of objectification of pulse examination referred in this article is feasible,and have gain the prospective effect.It provides a new method and characteristic data for the clinical study of objectification of pulse examination and teaching of TCM.

Objective To investigate the effects of RNA interference(RNAi)targeting human epithelial growth receptor-2(HER-2)gene on the invasive and chemotactic ability of SKOV3 cells. Methods Glyeeraldehyde-3-phosphate dehydrogenase(GAPDH)was used as the positive control. Lipofectamine 2000 mediated transient transfection was conducted to transmit the siRNA into SKOV3 cells. Three pairs of specifically targeted(HER-2 siRNA Ⅰ,HER-2 siRNA Ⅱ,HER-2 siRNA Ⅲ)sequence were selected in the coding region of HER-2 mRNA.Transfection of HER-2 siRNA was conducted with lipofeetamine 2000 in ovarian carcinoma cell line SKOV3.The HER-2 gene expression was assessed by real- time PCR and western blot assays.Changes of invasive and chemotaetie capacity of SKOV3 cells were measured by polycarbonates coated with or without matrigal.Results Western blot results showed that the expression of GAPDH protein was decreased in specifically transfected cells and with the increase of siRNA dose,the expression of GAPDH protein was decreased.GAPDH protein gray value in control group, different doses(0.5,1.0,1.5,2.0 ?g)GAPDH siRNA interference groups were 0.6855?0.0259,0.5698 ?0.0275,0.4542?0.0296,0.3341?0.0178 and 0.1816+0.0180,respectively.There was a significant difference in each group(F=198.126,P

Objective To investigate the neural mechanism of the reduction of switch cost induced by short presentation of the task cue.Methods The event-related potentials (ERP) was recorded from 19 subjects while they performed a Chinese Stroop switching task.The factorial design of repeated-measures was adopted with the cue presentation time (100/1000 ms) and the type of succeeding task (repeat/switch).Results For the switch cost of reaction time (the switch subtracts the repeat),the difference between the long cue group (15.0 ± 33.3 ms) and the short group (0.80 -±40.7 ms) had the significantly tendency( t (18) =- 1.77,P=0.09).During the stage of cue processing,the ERP effects of cue reveal in the frontal-occipital areas ( 100 ～ 200 ms),frontoparietal and tempo-occipital regions (200 ～500 ms),frontoparietal network and centro-occipital regions (500 ～900ms).During the stage of task execution,the ERP effects of the cue were observed from the left fronto-occipital areas ( 300 ～ 400 ms) to parieto-occipital areas (400 ～ 900 ms).The ERP effects of the task started from the right hemisphere (500 ～600 ms ) and extended to bilateral prefrontal and centro-parietal area (600 ～900 ms ).Conclusion The short cue presentation can not only start up the preparation of frontoparietal network earlier during cue processing stage but also enhance its retrieval in the left dorsal lateral frontal cortex during task executive stage.
