Objective To study the correlation between prognosis of non-small cell lung cancer ( NSCLC) patient and serum levels of HGF and IL-6. Methods Eligible 109 NSCLC patients and preoperative blood samples of each patient in our hospital from March 2013 to May 2014 were collected. Then the levels of HGF and IL-6 of serum samples were detected by using ELISA kit. All patients were followed up for 1 year. The neoplasm staging:67 cases were stagingⅠ-Ⅱ,38 cases were stagingⅢ,2 cases were staging IV. There were 79 cases with ad-enomatous carcinoma( ADC) ,26 cases with squamous carcinoma( SCC) and 4 cases with NSCLC. According to the TNM staging,there were 79 cases in pN( -) group,31 in pN( +) group,77 in pT(T1-T2) group and 28 in pT(T3-T4) group. Results The average concentration of HGF and IL-6 in serum were 860 pg/mL and 2. 7 pg/mL respectively. Analysis of survival indicated that,compared to those patient with lower serum level of HGF and IL-6,the survival rate of patient with high serum level was much lower. The difference was statistically signifi-cant (HGF,P=0. 019;IL-6,P=0. 002). The analysis of the patients with stageⅢdisease separately also indicated that survival rate of pa-tient with lower serum of HGF and IL-6 was higher than others. Conclusion The serum levels of HGF and IL-6 might be a effective indica-tors for predicting prognosis of the NSCLC paitents.

Objective To study the effect ofQianzheng powder through point directional transdermal drug delivery technique for the patients with urge incontinence(UI) after stroke.Methods Seventy patients with UI after stroke were randomly divided into treatment group and control group(each group 35 patients). Qianzheng powder through point directional transdermal drug delivery was given to the treatment group, but the tolterodine through mouth was given to the control group. The urinary diary and bladder function at baseline and after 2 weeks' treatment were observed.Results After treatment, the total effect rate(88.2%vs. 63.6%,χ2=5.575) in the treatment group were better than that in the control group (P<0.01).The duration of voided (17.05 ± 6.21 times/48 hvs. 28.63 ± 9.62 times/48 h,t=5.872), the times of urinary incontinence (2.08 ± 1.24 times/48 hvs. 7.19 ± 2.46 times/48 h,t=10.784), the average voided volume (282.38 ± 14.32 mlvs. 185.82 ± 15.43 ml,t=26.561), the times of nocturia (1.38 ± 0.34 times per nightvs. 2.45 ± 1.56 times per night,t=3.906), the initial Sensory capacity of bladder (246.76 ± 21.95 mlvs. 176.43 ± 20.64 ml,t=13.502), the maximum capacity of bladder (495.80 ± 26.72 mlvs. 295.81 ± 28.46 ml,t=29.663), the residual urine volume (12.25 ± 6.83 ml vs. 33.63 ± 7.25 ml,t=12.428) in the treatment group showed significantly more improvement than those in the control group (P<0.01).Conclusions TheQianzheng powder by point directional transdermal drug delivery could reduce the symptoms of urinary incontinence, and improve the life quality of patients with UI after stroke.

Objective:Based on Co-occurrence Matrix and Run-length Matrix,we studied cerebral infarction patients' MR image texture characters.The aim is to investigate the differences of lesion textures characters between patients' groups and normal control groups,so that we can use this tiny change to realize early diagnosis of cerebral infarction.Methods:Texture features were extracted from MR images of patients and normal control groups respectively.Fisher test was applied to choose valid textures characters and made features classifier.Results:Linear discriminant analysis can achieve 88.31% classification accuracy.This demonstrated that cerebral infarction patients and normal control groups have the differences of textures Characters in MR image.Conclusion:We can discover cerebral infarction patients' MR image texture characters change by texture analysis,so that early diagnosis of cerebral infarction would be realized.

OBJECTIVE:To observe the clinical efficacy and safety of recombinant human endostatin (rh-endostatin) combined with Lobaplatin for injection and irinotecan injection in the treatment of advanced recurrent small cell lung cancer (SCLC). METHODS:A total of 88 patients with advanced recurrent SCLC in our hospital were divided into control group (41 cases) and observation group (47 cases) according to random number table. Control group was given Irinotecan injection+Lobaplatin for injection. Observation group was additionally given Recombinart human endostatin injection 15 mg added into 0.9%Sodium chloride injection 250 mL,ivgtt,qd,for consecutive 14 d,every 14 d. A treatment course lasted for 28 d,and both groups were treated for 2 courses. The clinical efficacy,the levels of serum carcinoembryonic antigen(CEA),the scores physical state (ECOG) and quality of life (QOL) before,after treatment were observed in the two groups,and the survival and adverse reactions of the two groups were compared. RESULTS:The total response rate of observation group was 59.6%,which was higher than 43.9% of control group,but there was no statistical significance (P>0.05). Before treatment, there was no significant difference in serum CEA levels,ECOG scores or QOL scores,between 2 groups(P>0.05);after treatment,the serum CEA levels of the two groups were significantly decreased,and the observation group was significantly lower than the control group,with statistically significant (P<0.05). In observation group,ECOG scores decreased while QOL scores increased significantly,and significantly better than the control group,with statistical significance(P<0.05). The overall survival(OS)of observation group was 16.8 months,which was significantly higher than 11.5 months of control group,with statistical significance (P<0.05). The incidence of leucopenia in observation group was significantly higher than control group;the incidence of leucopenia and abnormal liver function were significantly lower than control group,with statistical significance(P<0.05). CONCLUSIONS:Rh-endostatin injection combined with lobaplatin and irinotecan can improve serum CEA levels and the quality of living aswell as prolong the survival time.

Objective:To develop a liquid chromatography/tandem mass spectrometry employing precolumn derivatization method for determination of peramivir in rat plasma.Methods: The sample preparation consisted of a protein precipitation extraction followed by derivatization with hydrochloric acid (10 mol/L) methanol (10∶90, v/v) and determined by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). The positive ion SRM mode was performed and the precursor-to-the-product ion transitions of m/z 343→284 and 299→152 were used to measure the derivative of peramivir and Ro 64-0802 (I.S.). The chromatographic separation was achieved using a Zorbax RX-C8 (2.1 mm × 150 mm × 5 μm) analytical column with an isocratic mobile phase composed of acetonitrile-water-formic acid (30∶70∶0.1, v/v/v, 0.2 ml/min). Results:The method was linear over a concentration range of 10 to 10 000 ng/ml. The LLOQ was 10 ng/ml. The average inter-day/intra-day precision values ranged from 5.0% to 7.1%, respectively, while the accuracy values ranged from 89.9% to 106.1%.Conclusion: In this method, retention time is greatly improved, the matrix effects are decreased by chemical derivatization. This method has been successfully applied to the preclinical and clinical research of peramivir.

ObjectiveTo analyze the relationship between result of hemorheology and non-pathological factors such as sex, age and life habit.Methods3483 healthy adults who had health examination were divided into different groups according to sex and age, and results of hemorheological test of them were analyzed and compared with reference values.ResultsAll hemorheological indexes of men were higher than that of women. The whole blood viscosity of female had an increasing trend along with the age increasing. However, the result of hemorheology of male showed that the index of the age of 30~49 was higher than the age of more than 50, and had a decreasing trend along with the age increasing after the age of 50. The index of high shear viscosity, low shear viscosity and hematocrit of both male and female were all higher than the reference values offered by apparatus.ConclusionEffect of non-pathological factors such as age, sex and life habit on index of hemorheology should be considered.
