OBJECTIVE To investigate the value of rigid bronchoscope combined with fiber bronchoscope application in children with airway obstruction.METHODS Retrospective analysis of 176 cases children with airway obstruction from January 1, 2006 to January1, 2016, all patients were diagnosised and treated in our hospital. RESULTS All children were acceptted rigid bronchoscopy combined with fiber bronchoscope under general anesthesia, then received the different thrapy according to the different causes. 104 patients with airway foreign body were all obtained satisfactory effect, 2 cases of children with bronchial foreign body(cap) inspection, failed to remove and contact thoracic surgery doctors to remove the foreign body by thoracotomy. 10 plastic bronchitis patients improved after treatment or cured. 7 cases of bronchial tuberculosis were cured after treatment. 4 patients with airway tumor after minimally invasive surgery, obtained good effect, 2 cases were turned to the other cancer hospital. 2 cases of patients with tracheal stenosis, the symptom is reduced after expansion. Bronchial granulation, tracheomalacia, bronchial softening, bronchial atresia patients improved after treatment. This group of all patients with pneumonia were cured after symptomatic treatment.CONCLUSION Rigid bronchoscopy and fiber bronchoscope are both useful for diagnosis and treatment of children with airway obstruction, both have its advantages and disadvantages, combined application can improve the accuracy of disease diagnosis and timely intervention on the patients.

Objective To investigate the expression of transforming growth factor?1(TGF-?1)in human colorectal carcinoma and its value for predicting the prognosis.Methods The expression of TGF-?1 and vascular endothelial growth factor(VEGF)was measured in specimens of 52 coloreetal cancers by immunohistoehemistry.The features of clinical pathology were analyzed and the follow-up of all patients were conducted.The correlation between the expression of TGF-?1 and the survival time was studied with Log-rank test.Results Of 52 patients,no expression of TGF-?1 and VEGF was observed in 11 and 14 patients,and the expression was noticed in 41 and 38 patients,respectively.There was a signifi- cant positive correlation between expression of TGF-?1 and expression of VEGF(x~2＝0.633,P＜0.01). Furthermore,the expression of TGF-?1 was significantly correlated with Dukes staging(x~2＝19.866,P＜0.01)and metastasis of lymph nodes(x~2＝13.152,P＜0.01).The 3-year overall survival rates(OSR)in all patients was 49.1% and the 3-year OSR of patients with and without expression of TGF-?1 were 20.5% and 69.2% respectively(x~2＝11.64,P＝0.0006).Conclusion The expression of TGF-?1 could be served as an important predicator for prognosis of coloreetal carcinoma.

Objective To analyze the safety and diagnostic value of ultrasound-guided biopsy with simple biopsy clip in children.Methods Under simple biopsy clip 52 cases were performed percutaneous renal biopsy.Then the curative rate and the incidence rate of complications were evaluated.Results Of 52 cases,49 cases(94.23%) gained enough renal tissue specimen for histological evaluation;Three failed cases occurred at early stage,nothing was found at later stage.The main complication was macroscopic hematuria occurred only once or twice after the operation and perirenal hematoma in 1.92% of the cases.No other severe complications were found.Conclusions The biopsy clip is convenient and sterile,and can guide the biopsy device exactly and safely.The use of 18-gauge biopsy gun and the automated biopsy device in children can decrease the complication rate,which can be easily performed.

Objective To explore the effect of the midwife-leading labor pain management model on the pregnancy outcomes and pain control satisfaction.Methods The randomized grouping and single blind trial design were performed.One hundred and ten pregnant women were recruited and randomized into the control group (n=55) and intervention group (n=55).The control group received the routine prenatal examination by the outpatientdepartment obstetric doctors and intrapartum nursing care during labor.On this basis the intervention group participated in the labor pain educational course in the midwife clinic,and received the repeated pain assessment and pain management intervention during labor.Results There was no statistical difference in the delivery mode between the two groups(P＞0.05).The cesarean section rate without indication in the intervention group was significantly lower than that in the control group,the difference was statistically significant(x2 =6.798,P＜0.05).The average each item score of the labor pain education and pain control satisfaction in the intervention group was significantly higher than that in the control group,the difference was statistically significant(P＜0.01).Conclusion The midwife-leading labor pain management model can reduce the cesarean section rate without indication,and improves the satisfaction of labor pain education and pain control in pregnant women and parturients.

Objective To establish an index system of the key factors of elimination of schistosomiasis. Methods A ques?tionnaire was designed based on the reference review,and 24 scientists working in the field of schistosomiasis control or re?search or management were investigated by using the Delphi method. The importance of each index reflecting the endemicity of schistosomiasis was scored by each scientist. The assessing system for key factors of eliminating schistosomiasis was established , and the normalized weight and combined weight were calculated. Results The assessing system included three indexes in the first grade,seven indexes in the second grade and thirteen indexes in the third grade. Among the indexes in the first grade,the normalized weights of endemicity,natural environment and social environment were 0.371 1,0.339 5,and 0.289 4,respective?ly. Among the indexes in the second grade,the economy showed the highest combined weight of 0.289 4 while the agriculture and sanitation both showed the lowest score of 0.112 7. Among the indexes in the third grade,the infection rate of animals showed the highest combined weight of 0.124 6 while the agriculture and plant structure both showed the lowest score of 0.053 0. Conclusion The indexes of the assessing system provide the scientific evidence for surveillance work when elimination of schis?tosomiasis.

Objective To analyze negative lymph nodes of 34 non-small cell lung cancer(NCLC) patients with total correction by means of fluorescent quantitation PCR and immunohistcchemistry,and to form molecular bi- ology staging.Methods Clinical data and tissue samples of 193 lymph nodes were collected from 34 patients under- going resection for non-small cell lung cancer.Using fluorescent quantitation reverse transcription-polymerase chain reaction(RT-PCR) and immunohistochemistry method,lymph nodes were examined for CEA gene mRNA,P53 and CK to form molecular biology staging.All the patients were followed-up for an average of forty months.Results The CEAmRNA was identified in 21.7% (42/193) lymph nodes negative patients from 17 patients(17/34,50%); TMN staging was up-regulated in 8 patients;positive lymph nodes were increased in 9 patients.P53 and AE1/AE3 were identified 9.8%(19/193) from 11 patients,18.6 % (36/193)from 15 patients,separately;TMN staging was up-regulated in 2 patients of P53 examination and 5 patients of AE1/AE3 analysis;positive lymph nodes were in- creased in in 7 patients of P53 examination and 11 patients of AE1/AE3 analysis.There was obvious statistical sig- nificance in them,but the molecular biology staging based on the three markers was not an independent factor on re- currence and metasis of lung cancer.Conclusion CEAmRNA.P53 and AE1/AE3 analysis could find lung cancer micrometasis more sensitively to form molecular biology staging which was relative to the prognosis,but not an inde- pendent prognostic indicator.It might be good to the therapy strategy after operation.
