Objective To evaluate the value of combined hepatectomy in radical resection for hilar cholangiocarinoma. Methods The clinical data and follow-up data of 67 patients of resection for hilar cholangiocarinoma in Henan Tumor Hospital from June 2005 to october 2008 were retrospectively analyzed. Results According to intraoperative exploration situation and bismuth types, tumor resection was combined performed with hepatectomy (n＝38)or non-hepatectomy (n＝29). The rate of R0 resection was 55.3% in hepatectomy group(n＝21) and 34.5% in non-hepatectomy group(n＝10), and the difference was significant（P＝0.024）. The incidence of complications were 39.5% in hepatectomy group(n＝15) and 13.4% in non-hepatectomy group(n＝4), and one patient with liver and kidney failure died in hospital. The 1, 3, 5 years of survival rate were 89.3%,53.6% and 32.1% respectively in R0 group (n＝31) and 69.7%,30% and 10% respectively in R1～R2 group(n＝36), there were significant differences in the postoperative survival rate between both groups（P＝0.018). The 1, 3, 5 years of survival rate were 81.8%,48.5% and 24.2% in hepatectomy group and 75%,32% and 16% in non-hepatectomy group respectively, and the differences were significant（P＝0.037). Conclusions Aggressive resection including combined hepatectomy for hilar cholangiocarcinoma can play an important role for curative effect and long term survival rate.

Objeetive To analyze the clinical significance of serial microproteinuria and urease detection in early diagnosis of antibiotics damage to kidney by observing the changes of urine microalbumin/creatinine ratio (mAlb/Cr),transferrin (TRF),IgG,α1-microglobulin (α1-M G),β2-microglobulin (β2-M G),retinol-binding pmtein(RBP) and N-acetyl-β-D-glucosaminidase(NAG).Methods A total of 161 children with pneumonia whose test results were normal of urine protein,blood urea nitrogen (BUN) and serum creatinine (Scr),and had no related history of kidney diseases were selected.All the patients were divided into three groups according to antibiotics for the treatment,the penicillins (penicillin G,amoxicillin and potassium clavulanate,ticarcillin and potassium clavulanate) group,the cephalosporins (cefazolin,cefuroxime,ceftriaxone,cefoperazone,ceftazidime) group and the macrolides (erythromycin,azithromycin) group.Changes of mAlb/Cr,TRF,IgG,α1-MG,β2-MG,RBP,NAG,BUN,Scr levels of the patients one week before and after use the antibiotics were observed,and statistically analyzed.Results In the penicillins group and macrolides group,the results showed that none of the serial microproteinuria and urease changed(all P ＞ 0.05).In the cephalosporins group,the urine mAlb/Cr,TRF,β2-MG and NAG were higher than before using the antibiotics [(15.56 ± 5.98) mg/g vs.(21.08 ± 10.88) mg/g,(1.61 ± 0,14)mg/L vs.(1.66 ±0.14) mg/L,(0.25 ±0.09)mg/L vs.(0.28 ±0.11)mg/L,(4.62 ±3.80) U/L vs.(4.98 ±3.97) U/L,t =-5.11,-3.24,-2.29,-2.04,P ＜ 0.05 ～ 0.001].The levels of BUN and Scr revealed no change in all the patients(all P ＞ 0.05).Conclusion Combined detection of serial microproteinuria and urease has great clinical significance in judgment and warning of early renal damage by antibiotics.

Objective To analyze the expression of Yes-associated protein and risk factors in differentiated thyroid carcinoma. Methods Clinical data of 152 patients with differentiated thyroid carcinoma and 27 cases of benign thyroid tumor from Changji Hui Autonomous Prefecture People’s Hospital of Xinjiang, were analyzed retrospectively. According to the expression levels of Yes-associated protein in differentiated thyroid cancer and benign thyroid tumor, univariate Chi-square test and multivariate Logistic regression methods were used to analyze the relationship between Yes-associated protein and gender, age, thyroid stimulating hormone(TSH) level, nodule size, capsule integrity, histological type and lymph node metastasis, in order to find out risk factors in differentiated thyroid cancer. Results The positive rate of expressed Yes-associated protein in benign thyroid tumor group was 66.7%(18/27), which was significantly higher than 31.58%(48/152) of differentiated thyroid cancer group, and the difference was statistically significant(χ2=12.127, P<0.01). Under an optical microscope, changes of Yes-associated protein were found to be mainly located in the nucleus and cytoplasm , and in benign thyriod tumor the degree of staining was deep, strong positive or moderately positive; differentiated thyroid carcinoma was lightly stained or no staining, weakly positive or negative. Chi-square test showed that the expression of Yes-associated protein was not affected by sex, age and pathological type(χ2= 0.419, 0.221, 0.315, all P >0.05); TSH level, nodule size, capsule integrity, lymph node metastasis had an impact on the expression of Yes-associated protein which was down regulated (χ2=4.020, 8.424, 4.386, 6.673, P<0.05 or<0.01). Logistic regression analysis showed that the nodule size was not a risk factor ( odds ratio , OR ) of Yes-associated protein expression (OR=1.929, P>0.05); TSH levels above 4.5 mU/L, lymph node metastasis and envelope incomplete were risk factors that down regulated the expression of Yes-associated protein (OR=2.167, 2.665, 3.048, all P<0.05). Conclusion Yes-associated protein is down regulated in differentiated thyroid cancer. Elevated TSH levels , incomplete capsule and lymph node metastasis are risk factors of Yes-associated protein down expression and differentiated thyroid cancer.

Objective To assess the efficacy and safety of nebulized hypertonic saline solution in infant with bronchiolitis.Methods From January 2014 to January 2016,95 patients at 3-13 months old in our hospital who diagnosed as bronchiolitis were randomly divided into three groups.On the basis of conventional suit support treatment,the observation group A was given nebulized 3％ hypertonic saline (n =32),the observation group B was given nebulized 3％ hypertonic saline and salbutamol (n =32),and the control group C was given nebulized normal saline (0.9％) and salbutamol (n =31),this therapy was repeated every 6 hours until discharge.The Lowell score,clinical symptoms remission time,days of hospitalization and incidence rate of adverse reaction of the three groups were compared.Results After treatment,the symptoms and signs of the three groups were all improved.The Lowell scores were lower in the two observation groups compared to the control group C in 24,48,72 hours after treatment[(5.81 ±1.53) points and (5.85 ± 1.37) points vs.(6.61 ± 1.54) points,(4.75 ± 1.34) points and (4.72 ± 1.30) points vs.(5.52 ± 1.29) points,(3.19 ± 1.15) points and (3.22 ± 1.16) points vs.(3.90 ± 1.01) points,Z =-1.999,-2.241,-2.518 and-2.002,-2.335,-2.316,all P ＜ 0.05).And the cough,wheezing remission time and pulmonary rales disappearance time,days of hospitalization in the two observation groups were also shorter,there were statistically significant differences [(6.63 ± 1.41) d and (6.56 ± 1.37) d vs.(7.35 ± 1.25) d,(5.19 ± 1.03) d and (5.25 ± 1.05)d vs.(5.87 ± 1.09)d,(5.75 ±1.34)d and (5.72 ± 1.51)d vs.(6.68 ± 1.60)d,(7.25 ± 1.37)d and (7.16±1.48)d vs.(8.10±l.47)d,Z=-2.498,-2.469,-2.359,-2.213 and-2.982,-2.405,-2.373,-2.222,P ＜0.05,or P ＜0.01)].There were no significant differences in the Lowell score,the length of time of cough,wheeze,lung rales disappears and the length of hospital stay between the observation group A and observation groupB[(5.81 ± 1.53) points vs.(5.85 ± 1.37) points,(4.75 ± 1.34) points vs.(4.72 ±1.30) points,(3.19± 1.15) points vs.(3.22 ± 1.16) points,(6.63 ± 1.41) d vs.(6.56 ± 1.37) d,(5.19 ±1.03)d vs.(5.25 ± 1.05)d,(5.75 ± 1.34) d vs.(5.72 ± 1.51) d,(7.25 ± 1.37) d vs.(7.16 ± 1.48) d,Z =-0.164,-0.021,-0.140,-0.295,-0.167,-0.374,-0.233,all P ＞ 0.05].Children in three groups had no serious adverse events (all P ＞ 0.05).Conclusion Nebulized hypertonic saline in the treatment of bronchiolitis can relieve symptoms and signs,shorten the hospitalization time,and has less adverse reaction,it is worthy of clinical use.
