Objective:To study the influence of neurogenic anorectum induced by myelodysplasia on function of anorectum.Methods:Twenty-five patients with myelodysplasia were evaluated by anorectal manometry.The function of anal sphincter was evaluated by resting pressure,contractive pressure and the length of high pressure;The sensation of rectum was evaluated by rectal maximum volume threshold;The function of defecation reflex was evaluated by rectoanal inhibitory reflex.Results:Anal resting pressure in the children with neurogenic anorectum induced by myelodysplasia( 25.8?3.4)mmHg was lower than that in normal children(66.7?24)mmHg.The maximum contractive pressure of anus in patients (86.6?20.1)mmHg was lower than that in normal children(129.0?18.8)mmHg.The length of high pressure in patients (17.5?4.5)mm was lower than that in normal children(23.6?4.6)mm.The rectal volume at sensory threshold in patients(62.1?8.5)ml was higher than that in normal children(36.0?12.6)ml.Rectal maximum volume threshold in patients(141.4?22.6)ml was higher than that in normal children (109.5?12.2)ml.Rectoanal inhibitory reflex was identified in both patients and normal children.Conclusions:Anorectal manometry may provide objective assessment of the neurogenic damage of anorectum in myelodysplasia including the damage of sphincter and the decrease of the rectal sensation. Rectoanal inhibitory reflex was identified in both patients and normal children. The major objective of anorectal treatment for patients with myelodysplasia was to strengthen the function of external sphincter, internal sphincter and pelvis floor muscle and to repair the sensation of rectum.

Objective To study HRCT appearances,clinic value and pathological fundament of the pulmonary honeycombing.Methods 60 patients including three groups with pulmonary honeycombing underwent HRCT scan.The comparative study of HRCT-pathology was done in 6 pulmonary postmortems with honeycombing.Results On HRCT images,honeycombing cysts were round-like with air inside,the cyst walls included remains of pulmonary inherent components and hyperplastic fibrotic tissue in pathology.The diameter of cysts was small,58 cases of them belonged to small group(90.6%).The distribution of lesions was mainly at lower(47cases,71.9%)and peripheral lung zone(52cases,81.3%),but there were differences in different type of the diseases.The cysts might become larger and it is impossible to recovery.Conclusion The honeycombing cysts appear as cystic cavities arranging as multiple layers,the cystic walls consist of different tissues in pathology,that are the manifestations of the end-stage of pulmonary fibrosis.HRCT appearances in different patients in three groups were different.

Objective To observe the effect of biofeedback therapy combined with electrical stimulation in patients with traumatic faecal incontinence.Methods Eishty-two patients with traumatic faecal incontinence were treated once daily with electric stimulation delivered via an intra-anal electrode.They also followed a biofeedback regimen including strengthening,sensory and coordination biofeedback.The whole progrtun consisted of 3 sessions of supervised treatment in hospital followed by 3 sessions of home therapy(10 days per session with an interval of 7days between the sessions).Clinical scores and anorectal function were assessed before and after the program.Results Before treatment,there were 9 patients with good clinical scores,and the general rate of fair and poor clinical scores Was 89%.After therapy,61 patients had good scores,and the general rate of fair and poor Was 26%.Anorectal squeeze pressure and sphincter electromyographic amplitude had improved significantly,the rectal sensory threshold Was decreased significantly,and 76%of the patients who had no external anal sphincter reflex recovered.At the two years follow-up,68% of the patients had maintained the clinical outcomes.Conclusion Biofeedback therapy in conjunction with electrical stimulation has significant therapeutic effects on patients with traumatic faecal incontinence.

ObjectiveTo investigate the possible mechanisms for biocompatibility of chitosan material using agarose/chitosan blended hydrogels as a model.Methods A series of agarose/chitosan blended hydrogels with different chitosan content were prepared by the blending method.The chemical groups of the blended hydrogels were analyzed by the Fourier transform infrared (FTIR) spectroscopy.The blending compatibility between the agarose and chitosan was evaluated with the fluorescein-4-isothiocyanate (FITC) staining method.The charge of the blended hydrogels was determined by the zeta potential measurement.The adsorption of total fetal bovine serum (FBS) proteins and bovine serum albumin (BSA) on the blended hydrogels was measured by the bicinchoninic acid (BCA) method.The adsorption of fibronectin (FN) on the blended hydrogels was measured with ELISA.Cell culture experiment adopted human microvascular endothelial cell line (HMEC-1) as the model.The cytocompatibility was studied by evaluating adhesion,proliferation,and morphology of the cells on the blended hydrogels.Results Characteristic chemical groups of chitosan could be detected in the agarose/chitosan blended hydrogels.The chitosan had a good blending compatibility with the agarose.The amino groups of chitosan were uniformly distributed in the blended hydrogels.The blended hydrogels were strongly positively charged at acidic pH (pH 3.0),however,the zeta potentials of all the hydrogels were reduced to nearly 0 mV at neutral pH (pH 7.4).There were no significant differences in the adsorption of total FBS proteins and BSA between the blended hydrogel groups.However,the adsorption of FN on the hydrogels significantly increased with the increase of chitosan content.Cell culture experiment indicated that the cytocompatibihty of the blended hydrogels was significantly improved with the increase of chitosan content.The HMECs exhibited higher levels of adhesion,spreading,and proliferation on the hydrogels with higher chitosan content.ConclusionResults in this study indicated that the chitosan component preferentially adsorbed FN compared to the other serum proteins,leading to adhesion and spreading of the cells on the blended hydrogels.In contrast to prevailing views,it was found in the present study that the biocompatibility of chitosan did not relate to its positive charge.

Objective: To investigate the shortterm efficiency of overflow fecal incontinence treated by biofeedback and electrical stimulating therapy.

The grading of clinical incontinence degree ,measurement of pressure of the anus and rectum, electromyogram of muscles of solum plevis were done before and after the therapy. Results: Followup was done for a mean of 4.5 years (range 3 to 5), the subjective scores, maximum contractive pressure of anus, last contractive time, rectal volume at sensory threshold, contraction amplitude of external anal sphincter and pudenda neural latency were significantly different from the ones before treatment (P

Background: Pseudorabies (PR), caused by the pseudorabies virus (PRV), is an endemic disease in some regions of China. Although there are many reports on epidemiological investigations into pseudorabies, information on PRV gI antibody dynamics in one pig farm is sparse. Objectives: To diagnose PR and analyze the course of PR eradication in one pig farm. Methods: Ten brains and 1,513 serum samples from different groups of pigs in a pig farm were collected to detect PRV gE gene and PRV gI antibody presence using real-time polymerase chain reaction and enzyme-linked immunosorbent assay, respectively. Results: The July 2015 results indicated that almost all brain samples were PRV gE gene positive, but PRV gI antibody results in the serum samples of the same piglets were all negative.In the boar herd, from October 2015 to July 2018 three positive individuals were culled in October 2015, and the negative status of the remaining boars was maintained in the following tests. In the sow herd, the PRV gI antibody positive rate was always more than 70% from October 2015 to October 2017; however, it decreased to 27% in January 2018 but increased to 40% and 52% in April and July 2018, respectively. The PRV gI antibody positive rate in 100-day pigs markedly decreased in October 2016 and was maintained at less than 30% in the following tests. For 150-day pigs, the PRV gI antibody positive rate decreased notably to 10% in April 2017 and maintained a negative status from July 2017. The positive trend of PRV gI antibody with an increase in pig age remarkably decreased in three tests in 2018. Conclusions The results indicate that serological testing is not sensitive in the early stage of a PRV infection and that gilt introduction is a risk factor for a PRV-negative pig farm. The data on PRV gI antibody dynamics can provide reference information for pig farms wanting to eradicate PR.
