Objective Surgical treatment of lung cancer needs to follow strict quality control standard for the aims of accuracy of pathological staging and potentially improved prognosis.However,there are short of studies related to surgical quality analysis.Methods One hundred and twelve patients were enlisted with the diagnosis of lung cancer and received surgical intervention in 2007.Surgical quality of these cases were retrospectively analyzed in compliance with three international standards,National Comprehensive Cancer Network (NCCN),American College of Surgeons’ Oncology Group (ACOSOG),and International Association for the Study of Lung Cancer (IASLC).Results No surgical death was reported in this group.According to NCCN,ACOSOG and IASLC standards,qualified operations were 82 cases (80.4％),73 cases (71.6％),45 cases (44.1％) in 102 cases with R0 resection,respectively.The median total lymph nodes,median mediastinal nodes,and N1 nodes were 27 (range 0-63),16.5 (range 0-43),and 10.5 (range 0-26),respectively.The median mediastinal node stations resected were 4 (range 0-6).In the mediastinum,stations of 4R,5,6 and 7 presented the highest frequency of receiving lymph node dissection.For N1 stations,10 and 12 were among the top list.For the whole group,1-year survival,3-year survival and 4-year survival were 92％ (95％ CI,89-95),67％ (95％ CI,62-72),57％ (95％ CI,52-62),respectively.Conclusion Quality control is the essential part of surgical treatment of lung cancer,which will facilitate the baseline standardization of clinical research.Since IASLC provides the strictest standard for lung cancer surgery,we suggest that all thoracic surgeons need to follow this standard to secure the accuracy of pathological diagnosis and for a potential better prognosis.

Objective To explore the puberty and height development in childern with congenital adrenal hyperplasia(CAH) due to 21-hydroxylase deficiency(21-OHD) with the simple virilizing(SV) form.Methods Patients of SV 21-OHD,diagnosed and treated in Tianjin Children's Hospital from Jan.1970 to Jan.2008,were treated with cortisone acetate or hydrocortisone after diagnosed,and blood investigations were performed as part of monitoring,and dosages were adjusted accordingly to obtain normal growth velocity and slow bone age(BA) development.Gonadotropin-releasing hormone agonist(Gn-RHa) was given after the appearance of central precocious puberty(CPP).Forty-one patients(18 females,23 males) had achieved final height before Dec.31st 2008,and their puberty and height development were analyzed in this longitudinal study by contrast the ages and statures of obtaining final height(FH),chronological age(CA) and BA of G2/B2 stage,duration from G2/B2 stage to obtain FH and stature development of different gender during this period and the influences of compliancy on the ages and statures of obtaining FH were contrasted.Results With regarding to the age of testicular volume ≥4 mL,78.26% boys were before 9 years old.As far as the age of breast development was concerned,38.89% girls were before 8 year old and 66.67% menarche occurred before 10 year old.The differences between the duration and stature development of the period from the state of G2/B2 to skeletal maturation of different gender were significant (Pa

Objective To analyze rate of and reasons for not undertaking insulin pump therapy in children with type 1 diabetes(T1DM) and explore potential countermeasures.Methods Two hundred and seventy-eight persons of T1DM,diagnosed in Tianjin Children′s Hospital from Jan.2000 to Dec.2008,were assigned to fill in a questionnaire on T1DM and insulin pump therapy.Reasons for different compliances were analyzed and strategies were explored.Results Eighty-five point twenty-five percent of the children(237 persons) undertook the therapy and 14.75%(41 persons) refused.In the group of younger than 3 years,58.33%(21 persons)accepted the therapy,while in the group of older than 3 years,89.26%(216 persons) undertook it,consequently there was statistically significant difference(?2=23.83,P

Objective To investigate the effects of α-lipoic acid on mitochondrial energy metabolism of liver in the rat with obstructive jaundice. Methods Seventy-two male SD rats were randomly divided into groups of sham operation and bile duct-ligation + normal soldium( BDL + NS) and bileduct-ligation + α-lipoic acid( BDL + LA). Malondialdehyde(MDA) , superoxide dismutase(SOD) and ATP, ADP, AMP in rat liver's mitochondrion were examined on days 7,14,21 after operation. Results MDA contents, ADP contents and AMP contents of liver' s mitochondrion were significantly increased at each time point in BDL + NS-group,while SOD contents and ATP contents of liver' s mitochondrion decreased remarkably on the 7th, 14th days; MDA content of liver' s mitochondrion in BDL + LA group was more lower than that in BDL + NS group (P ＜ 0. 01 )on the 21st day; MDA content was further increased in BDL + NS group and in BDL + LA group but there was no difference in their comparisons. On the 7th, 14th days, SOD contents and ATP contents in BDL + LA group were significantly higher than that in BDL + NS group( 7th days,P ＜ 0. 01; 14th days,P ＜ 0.05 ), On the 21 st day SOD contents in BDL + NS group had no difference with that in BDL + LA group (P ＞ 0. 05). Conclusions LA has a protective effect on energy metabolism of liver' s mitochondrion in the initial ,metaphase stage of obstructive jaundice.

Objective To investigate the clinical effect of magnesium sulfate combined with nifedipine in the treatment of patients with pregnancy induced hypertension( HDCP) .Methods Retrospective study was used in this study and 116 patients with HDCP from January 2013 to July 2015 in department of obstetrics and gynecology from our hospital were divided into two groups, including routine group of 62 patients who received routine treatment +magnesium sulfate) and combination group of 54 patients who received routine treatment +magnesium sulphate +nifedipine.The clinical effect was analyzed after five days’ continuous treatment.Results The systolic blood pressure, diastolic blood pressure,24h urinary protein, random urine protein /creatinine,serum homocysteine (Hcy) and CRP values in combination group were lower than routine group (P<0.05).There were no statistical difference in maternal uterine inertia, neonatal asphyxia, fetal distress, postpartum hemorrhage rate between the two groups after the treatment.But the rate of cesarean section in the combination group(50.00%)was significantly lower than that in the routine group(68.25%)(P <0.05).Conclusion Magnesium sulfate combined with nifedipine in the treatment of patients with HDCP had better antihypertensive effect, and would not increase fetal adverse birth outcomes incidence and significantly reduce the rate of cesarean section.

Purpose To investigate the prognostic significance of NQO1 protein expression in colorectal carcinoma ( CRC) patients. Methods 192 cases of primary CRC, 28 of colonic dysplasia, and 44 of adjacent non-tumor tissues were selected for immunohisto-chemical staining of NQO1 protein. Correlation between NQO1 overexpression and clinicopathologic characteristics, and the survival rates were calculated by the statistical methods. Results The strongly positive rate of NQO1 protein in CRC was significantly higher than that in gastric dysplasia and adjacent non-tumor tissues (P<0. 01, respectively). NQO1 high-expression rate was positively cor-related with differentiation, serosal invasion, lymph node metastasis, and clinical stage (P <0. 05, respectively). Survival curve showed that the disease-free survival and 5-year survival rates of the patients with high NQO1 expression were obviously shorter than those of patients with low NQO1 expression (P<0. 001, respectively). Further analysis showed that, high expression of NQO1 predic-ted the lower disease-free survival and 5-year survival rates in late-stage patients (P<0. 01, respectively). Importantly, NQO1 was an independent risk factor for the prognosis of CRC using Cox proportional hazards regression model ( HR: 1. 398,95%CI: 1. 011 ~1. 934, P=0. 043). Conclusions Detection of NQO1 protein expression in CRC has an important clinical significance, and it is ex-pected to become a new biomarker for CRC.

Objective To explore the therapeutic effect and possible mechanisms of Xuebijing injection for treatment of acute pulmonary thromboembolism(APE)in rabbits. Methods Twenty-four New Zealand rabbits with big ears were randomly divided into control group,model group and Xuebijing group(each n=8). The model of APE was performed by re-infusing of autologous blood clots. After the model was established,in the rabbits of the Xuebijing group,Xuebijing injection 1 mL/kg was injected into the ear marginal vein,twice daily for consecutive 7 days. In the model and control groups,the same amount of normal saline was given via the same route. The changes in plasma levels of B-type natriuretic peptide(BNP)were detected by enzyme-linked immunosorbent assay(ELISA) at the time points of 8 hours and 1,3,5,7 days,and after 7 days the lungs of the rabbits were removed for the lung histopathological examination. Results The BNP levels of the model group and Xuebijing group were significantly higher compared with the level of control group at 8 hours after embolization,the model group being the most significant(all P<0.05). On day 3,the BNP levels of the model group and Xuebijing group reached their peaks,and then gradually decreased,but the level of model group was significantly higher than that of Xuebijing group(ng/L:581.1±144.6 vs. 251.5±22.5,P<0.05). On day 7,the BNP level of Xuebijing group fell to the level of the control group(ng/L:78.5±9.4 vs. 50.9±11.5),the level of the model group also decreased,but it was still much higher than that of the Xuebijing group(ng/L:214.1±47.6 vs. 78.5±9.4,P<0.05). Histopathological examination showed Xuebijing could significantly reduce the infarct size with mild inflammatory cell infiltration,but the infarct size of the model group was obviously bigger than that of the Xuebijing group and accompanied by relatively more inflammatory cell infiltration. Conclusion Xuebijing injection can significantly reduce the plasma BNP level of the rabbits with pulmonary embolism,and in the mean time ameliorate the degree of inflammatory infiltration in the lung tissue and infarct.
