ERAS,namely enhanced recovery after surgery,refers to the implementation of optimized EBM (evidence-based medicine) measures comprised of preoperative preparation,anesthesia and postoperative management,in order to reduce psychological stress and physiological trauma,thus contributing to rapid recovery.Recently,researches focus mainly on adult ERAS and are rarely seen in pediatric surgeries.Considering the more sophisticated process children faced,it is urgent and strongly-needed to enforce optimization of perioperative management in pediatric surgeries.Difficulties and challenges exist in the process of ERAS in pediatric surgery,such as the break-through of traditional concepts,cooperation between departments of the anesthesiology and surgery,the fasting time issue,implementation of goal-di-rected fluid therapy,anesthesia method selection,analgesia mode and drug options.Prospective,multicenter clinical trials are needed to explore and solve the problems.In this paper,we review the present situation,difficulties,and prospects in ERAS of pediatric surgery.

Objective To construct and identify the shRNA plasmid vector targeting nuclear factor erythroid-2-related factor 2 (Nrf2),and to collect the strongest RNAi effect of Nrf2 shRNA sequence.Methods Nrf2 gene was targeted gene.Three shRNA sequences were designed by software and synthesized by chemical method: shRNA-1,shRNA-2 and shRNA-3.The double strand shRNA oligo was ligated to the vector.The construct was verified by sequencing analysis.BV2 cells were transfected with expressing shRNA plasmid vectors using Lipofectamine 2000.The expression of Nrf2 in the levels of mRNA was detected by real-time PCR,and Western Blot was adopted to abserve the expression of Nrf2 protein.Results Sequencing analysis suggested that the shRNA vectors targeting Nrf2 possessed correct nucleotide sequence and read frame.The result of Real-time PCR and Western Blot showed that the sequence of shRNAi-3 could more effectively knockdown the expression level of Nrf2 than the others.Conclusions The shRNA vectors targeting Nrf2 are successfully constructed and the shRNA can signidicantly inhibit the expression of Nrf2.These findings could provide an experimental basis for further study on Nrf2 signaling pathway in stroke field.

Objective　To evaluate the safety of biopsy of the prostate guided by transrectal ultrasound.Methods　Three hundred and seventeen patients suspected to have prostate cancer were examined and 208 patients were followed up.Results　One hundred and eighty-one patients followed up did not feel severe pain during the biopsy of the prostate. Clinical manifestations induded 12 cases of hematuria,4 dases of hematospermia,1 case of fever, 2 cases of pollakisuria and urodymia,2 cases of uroschesis,which disappeared after corresponding treatment.Conclusions　Biopsies of the prostate guided by transrectal ultrasound is advantageous in diagnosis of prostatic carcinoma.

OBJECTIVE: We used electrophysiological methods to study that whether GABA could elicit OHCs outward currents provide evidence for exsitence of GABA-A receptor and investige the relationship between the effect of GABA and the development of OHCs. METHOD: We used whole-cell recording OHCs at current-clamp or voltage-clamp to verify the function of GABA receptor on OHCs. Then we counteds the responsive cells vs. total number cells, and according to results to study the relationships between the GABA receptor and development of OHCs. RESULT: OHC was elicited outward current or hyperpolarized by GABA and the responsive cells were decreased with development. CONCLUSION The result of GABA receptor decreasing with development suggested that the receptor may draw efferents to OHCs or facilitate the MOC-OHC synapse formation.

To study the effects of connective tissue mast cells ( CTMCs ) on T cell activation in an antigen-dependent manner.Methods: Connective tissue mast cells were differentiated from mouse bone marrow cells.Alexa Fluor 488-conjugated ovalbumin (OVA)/IgG immune complexes were generated and incubated with CTMCs ,and analyzed by flow cytometry to detect the antigen uptake by CTMCs via Fcγreceptors ( FcγRs ).The relevant effects on antigen-specific T cell activation and proliferation were further determined by CD 69 and Ki67 expression.Results: A magnificent increase in OVA uptake was seen in CTMCs treated with OVA/IgG immunocomplex after 24-hour incubation ,compared with that treated with fluorescent OVA alone.OVA-incorporated mast cells induced OVA-specific CD4+T-cell activation and proliferation.Conclusion:It was suggested that the binding of IgG receptor FcγRs could elicit CTMCs reaction and ,as a result,to mediate crosstalk between professional APCs and T cells.

Objective:To explore the strain experiences by suicides and to test the strain theory of suicide.Methods：A consecutive sample of 155 suicides(91 males and 64 females)aged from 15 to 34 years was studied with the psychological autopsy method.Informants consisted of family members and close friends of the suicides.Suicide stories were composed based on the background information of the suicides and what happened at the suicide site and then content-analyzed and rated by independent judges.Results:All of the victims had experienced at least one type of strain before suicide took place.The sequence of the 4 types of strains beginning with the most frequent one was coping strain,100%;aspiration strain,81%,deprivation strain,72% and value strain,45%.Generally,males experienced more coping strains,especially loss of money or investment than females [(8.85±3.64)vs.(7.72±3.77),(0.35±0.92)vs.(0.09±0.52);Ps<0.05],except for the traditionalism and modernity for status of women,religion and atheism [(0.08±0.37)vs.(0.53±0.97),(0.00±0.00)vs.(0.06±0.30);Ps<0.05].As age increased,value strain tended to increase(r= 0.16,P=0.048),whereas aspiration strain tended to decrease(r= -0.30,P<0.001).Conclusion：With the prevalence of dissonant stresses among suicide victims,it is suggested that crisis intervention and suicide prevention should begin with strain reduction through psychological counseling and therapy.
