Airway obstruction in children is a rare,in recent years,with the development of CT technology and the development of fiber bronchoscopy,the number of cases of children with tracheal stenosis has increased year by year,but difficult clinical problem,with no clear agreement on optimal therapeutic approach.Stenting of the airway has been used successfully in adults,and is an attractive alternative in children.Fundamental differences of pediatric compared to adult use include the benign nature of most stenoses,the narrow and soft airways of children,the required long-term tolerance and adaptation to growth.So it is controversial in the indications.

Objective To investigate and analyze the residents′knowledge and satisfaction on basic public health services in five districts of Gansu ,to judge the implementation effect of the current policy ,in order to provide the suggestion to improve the effect of the implementation of the policy of basic public health services .Methods Based on typical sampling method ,1 688 rural and urban residents had been investigated coming from five counties in Gansu by using questionnaires to survey .Results The de‐gree of residents′knowledge about the policy was low (57 .23% );the residents could know about the policy through a variety of ways ,and mainly for medical staff to promote by approaching their homes ;91 .94% of surveyed residents thought that policy service was more convenient when they were accepting ;90 .99% of surveyed residents thought that they satisfied with the service attitude of staff ;82 .35% of surveyed residents believed that the policy service effects was obvious ;90 .11% of surveyed residents overall satisfied with the service of policy .The above results were different in proportion in various counties(P<0 .05) .Conclusion The degree of residents′knowledge and satisfaction on basic public health services in five districts of Gansu still needs to be improved .

Objective To explore the rehabilitation outcome and influencing factors of functional recovery in patients with nontraumatic spinal cord injury (NTSCI). Methods A retrospective analysis was done on 49 cases suffering from NTSCI who recepted rehabilitation therapy from December 2014 to November 2016. The main indicator of the rehabilitation effect was Modified Barthel Index (MBI). A total of 49 cases were divided into two groups, effective group (31 cases) and ineffective group (18 cases) according to whether their MBI on discharge had beated the target setted on admission. The following factors:ages, gender, injury causes, injury level, injury grade, injury severity, the types of paralysis, hospitalization time, sick time, complications number, MBI on admission and discharge, operation, early rehabilitation were evaluated by Univarite analysis and Logistic stepwise regression to assess how they influenced rehabilitation outcome. Results After systematically rehabilitation training, MBI had apparent improvement, from (38.98 ± 24.90) score on admission to (56.35 ± 22.69) score on discharge and had statistical significance(Z=-4.95, P=0.00), which showed that rehabilitation training can effectively improve patients′ self-care ability of daily living. Regression analysis found that the MBI on admission (OR=1.044, P=0.010) and hospitalization time(OR=1.044, P=0.039) had a noticeable effect on the rehabilitation outcome, while all the other factors, such as age, sex, injury grade, injury level, injury severity, complications number hadn′t show concrete effect on rehabilitation outcome. Conclusions Patients with NTSCI should have early rehabilitation, medical staff should assess their admission MBI, make a strict rehabilitation training plan to improve rehabilitation efficiency, shorten hospitalization time, improve the patients quality of life.

Objective To investigate the effects of filter reuse on solute clearances, safety and oxidative stress parameters in on-line hemodiafiltration(HDF) . Methods 8 stable maintained uremic patients were treated by post-dilution on-line HDF with first-use or reuse F60 polysulfone filter, respectively. Both blood-side and dialysate-side solute clearances at 20 minute of HDF or during the whole session were measured. Whole blood interleukin-1?(IL-1?) production was monitored before HDF, after HDF, and at 20 minutes of HDF at both venous and arterial lines. Plasma before and after treatment and dialysate were collected for measuring total ascorbic acid, dehydroascorbic acid and total vitamin E. Restults No difference of small molecular substance clearances was observed in blood and dialysate side, while filter reuse group had a significantly higher dialysate side clearance and a significantly lower absorption clearance for ?2-microglobulin. In contrast with stable vitamin E concentration during dialysis, total ascorbic acid level decreased after treatment, with reuse group further inducing a reduced ration of dehydroascorbic acid to total ascorbic acid. No significant changes were found in whole blood IL-1? production within and between each group, so did intra-dialysis symptoms and temperature curves. Reuse filter also caused more albumin loss through high-flux membrane than that of first-use filter. Conclusions Although reuse filter can maintain both small and large molecular weight substance clearance, it increases albumin loss through high-flux membrane. Reuse filter does not stimulate white blood cell to produce more cytokine than the first-use filter, but it increases oxidative stress, and may harm uremic patients in a long run.

Objective To evaluate the clinical efficacy and safety of celiac continued circulatory hyper -thermia perfusion with chemotherapy in the treatment of cancer with ascites .Methods Databases including the Cochrane Library MEDLINE,PubMed,Embase,CBM,VIP,CNKI and WanFang Data,and the other sources as supplying .The literatures were screened according to the inclusion criteria ,extracted data and assessed the meth-odological quality ,and then meta -analysis was performed using RevMan 5.0.2 software.Results Totally 14 RCTs with 867 patients were included .Meta-analysis showed that compared intraperitoneal chemotherapy ,with celiac continued circulatory hyperthermia perfusion had a significant difference in CR ( OR=3.18,95%CI:2.18~4.64,P<0.00001),PR(OR=2.05,95%CI:1.51~2.77,P<0.00001),overall effective rate(OR=4.88, 95%CI:3.59~6.46,P<0.00001).The incidence of adverse reactions was no statistically significant in the two groups.Conclusion Celiac continued circulatory hyperthermia perfusion with chemotherapy in the treatment of cancer with ascites demonstrates better efficacy and safety ,but it still needs to verify the above conclusion .

Objective To investigate the relationship between helicobacter pylori(Hp) infection and Henoch-Schonlein purpura(HSP) in children and find out the etiological treatment for HSP.Methods Positive rate of Hp-IgG between normal children and children with HSP were compared.Infection of Hp was detected by rapid urease test,and relationship between infection of Hp and clinical symptom in Henoch purpura was analyzed.Children with HSP were randomly divided into two groups and were respectively treated with Hp eradication therapy together with conventional therapy and conventional therapy only.The recurrence rates were compared.Results The infection rate in 150 children with HSP,especially the 90 children with Henoch purpura was significantly higher than that in normal children,and it was in positive correlation with abdominal symptom.Hp infection with triplex therapy for 2 weeks in HSP could reduce the recurrence of HSP.Conclusions Hp infection may be one of the reasons of HSP in children,and is related with Henoch purpura.Eradication of Hp can reduce recurrence of HSP.

Objective To investigate the molecular and cell signal transduction mechanisms by Lactobacillus cell wall extract(LCWE)inducing human-β-defensin-2(hBD-2)expression in human vaginal epithelial cells.Methods The induction of hBD-2 in human vaginal epithelial cells(WZV-1)by LCWE was observed using real-time PCR and Western blot.After stimulating WZV-1.the activation of NF-κB and p38MAPK signaling pathways were determined by Western blot.The induction of hBD-2 in WZV-1 cells by LCWE was observed with signaling pathways inhibitors of NF-κB and p38MAPK using real-time PCR and Western blot.Results The results showed that LCWE significantly upregulated hBD-2 expression in the time and dose-dependent manner.The maximal stimulatory effect of LCWE on the expression of hBD-2mRNA in WZV-1 cells were observed at the concentration of 50μg/ml after treatment for 8 h.After stimulation by 50μg/ml LCWE,Western blot analysis demonstrated that the phosphorylation of p38MAPK increased at 0.5 h significantly,peaked at 1 h,moreover the concentration of NF-κB in nucleus increased at 0.5 h significantly(P<0.05),peaked at 2 h.Blocking with inhibitor of NF-κB and(or)p38MAPK pathways results in decreased levels of HBD-2 expression.Conclusion These findings suggest that p38MAPK and NF-κB pathways play the important roles in induction of hBD-2 expression by LCWE in human vagihal epithelial cells.

Objective To analyze the effect of cervical.curvature and intervertebral height on the surgical outcome of posterior decompression in patients with multi-level cervical spondylotic myelopathy.Method A total of 50 patients with multi-segment cervical spondylotic myelopathy (≥ 3 segments),treated with posterior decompression from June 2006 to January 2009 were retrospectively analyzed.Twenty six patients underwent cervical omni-posterior decompression and lateral mass screw internal fixation (group A); 24patients underwent expansive open-door laminoplasty (group B).The effects of changing of cervical curvature and intervertebral height on JOA score and VAS score were analyzed.Results All patients were followed up for 8 months to 4 years (average,24 ±5.5 months).There were statistical differences of cervical curvature angles between preoperative and 3 days postoperatively in group A,while no statistical differences in group B.There were no statistical differences of cervical curvature angles between 3 days,6 months and 3 years postoperatively in group A,while there were differences in group B After further analysis of the loss of cervical curvature and intervertebral height,the result showed that JOA score and VAS score in the low-loss group were better than those in the high-loss group.Conclusion Lateral mass screw internal fixation after cervical omni-posterior decompression had many advantages such as reducing the change of cervical curvature,the loss of intervertebral height and incidence of cervical axial symptoms.
