Objective To discuss the application effects of CBI teaching method in medical English Teaching of respiration medicine. Methods Dividing 120 students of Grade 2009 in Jining Medical College into two groups including control group (60) and experimental group (60). The tradi-tional teaching method was adopted in the control group and CBI teaching method was adopted in the experimental group. After finishing the courses, medical professional English level test and standard-ized patients test were applied in the two groups. Students' English studying interests and autonomous English learning ability were also investigated by questionnalres. SPSS 17.0 software was used for sta-tistical analysis, and the data were processed by t test and 字2 test, with the level of a test equal to 0.05. Results The medical professional English level test scores, standardized patients test scores and the total average scores of autonomous English learning ability in experimental group were respectively [(81.97±4.91), (80.33±5.85), (3.88±0.38)], and they were significantly higher than those in the control group [(70.40±4.78), (70.48± 4.79), (2.98±0.26), with P values below 0.01]. Satisfaction degrees in the improvement of learning motivation, learning time, learning method, learning attitude and dealing with study difficulties in experimental group were better than those of control group (χ2=13.084, 8.000, 13.297, 11.627, 13.374, P=0.000). Conclusion CBI teaching method is better than traditional teaching method and it transfers English learning into the learning of professional knowledge and skills of respiratory medicine, stirs the interests of students, improves their autonomous English learning ability and strengthens their abilities to learn and apply English language.

Prior to the formation of new metastases,a large number of cancer cells released from the primary tumor enter the dormancy period.Once the dorruancy is broken,tumor cells will recover the capability of proliferation.In recent years,various hypotheses and mechanisms of tumor metastasis have been studied.Primary tumor resection is considered to be an important factor to break tumor dormancy state.It is recognized as an important reason to promote tumor metastasis.The improvement of surgical technique and further study on the mechanism of dormancy may provide new ideas for the treatment of metastatic tumor.

Objective To investigate the clinical characteristics of diabetic retinopathy(DR)and diabetic nephropathy(DN)and their correlation. Methods All of 9237 hospitalized type 2 diabetes patients from January 2004 to June 2009 were collected. The prevalence and clinical of characteristics of DR and DN as well as their relationship were analyzed. Results The total prevalence of DR was 33.0%(3045/9237),and the prevalence of DR in the microalbuminuria, macroproteinuria and macroalbuminuria combined with renal dysfunction patients were 36.3%(588/1618),53.7%(1113/2074)and 70.7%(1206/1706)respectively.The prevalence of DN was 58.4%(5398/9237). Compared with that in the diabetes patients without DR, the levels of microalbumin and total protein in the urine were higher in the patients with moderate non-proliferative diabetic retinopathy(NPDR), serious NPDR and proliferative diabetic retinopathy(PDR), but the endogenous creatinine clearance rate was lower(P＜ 0.05). According to the non-conditional Logistic regression model,the risk factors of DR included diabetes duration,urinary protein,fibrinogen, C-reactive protein and peripheral neuropathy, and the risk factors of DN included diabetes duration, HbA1c, systolic blood pressure,urinary protein,low density lipoprotein and DR. Conclusions DR and DN are the chronic microvascular complications in the type 2 diabetes and have higher prevalence. There are good correlations between DR and DN.

Objective To explore the way to evaluate hemodynamics of posterior circulation distal ischemia with PWI. Methods Thirty-two patients with vertebral basilar artery severe stenosis were reviewed and compared with thirty normal persons. Information and data of PWI and MRA were collected and analyzed. Following parameters were observed, index of vascular stenosis, collateral vessels, cerebral blood flow (rCBF), cerebral blood volume (rCBV), and mean transit time (rMTT). Results All the patients had at least one vertebral basilar artery with more than 70% stenosis. There were 17 cases with severe vertebral artery stenosis , 20 cases with severe basal artery stenosis , 8 cases with severe superior cerebellar artery stenosis , 17 cases with posterior cerebral artery stenosis , 22 cases with after the traffic artery open , 11 cases with soft meningeal arteries show and 12 cases with small artery show. The ratio of ROI with frontal white matter was lower than the rCBF and rCBV in the country group. MTT value was extended and P value of the parameters in both groups was less than 0.05, reflecting the statistical difference. Conclusions PWI combined with MRA can effectively evaluate the posterior circulation distal ischemia area and tissue perfusion , as well as the hemodynamic status of ischemia area.

Objective To discuss the relationships between regular pattern changes of plasma fibrinogen (Fib),D-dimer and fibrinogen degradation products (FDP) levels and the recent dissolution of thrombus in patients with pulmonary embolism (PE) in 14 days after treatment.Methods A prospective study was conducted.PE patients admitted to Departments of Respiratory Disease in 4 hospitals from January 2015 to March 2016 were enrolled and all of them were treated with thrombolysis and/or anticoagulation after admission.The computed tomographic pulmonary angiography (CTPA) was examined pre-treatment and 14 days post-treatment in PE patients.The pulmonary artery obstruction index (PAOI) was assessed according to the Mastora scoring method to estimate the thrombus load.The plasma Fib,D-dimer and FDP levels were measured before and on 1,2,3,5,7 and 14 days after treatment,and the relationships between the change regularities of these parameters and PAOI were also analyzed.Results A total of 42 PE patients were enrolled.The curve change of coagulation-fibrinolytic system parameters in 14 days after treatment showed that the Fib level was raised to its peak on the 3rd day after treatment and then decreased (g/L:4.24 ± 1.45 vs.3.83 ± 1.56),representing that its curve change was in accordance with the quadratic model (P =0.095).After treatment,the D-dimer and FDP levels were kept declining,they were reached the valley on 14th day [D-dimer (mg/L):1.58 ± 1.38vs.8.84 ± 6.35,FDP (mg/L):4.23 ± 3.63 vs.23.41 ± 16.54],and their curve changes were in accordance with the cubic model (F was 32.190 and 34.326,respectively both P =0.000).The PAOI variation before and 14 days after treatment [(18.77 ± 14.22)％] was not correlated with Fib variation [(1.20 ± 0.93) g/L,r =-0.194,P =0.219],but was positively correlated with D-dimer variation [(7.29 ± 7.10) mg/L] and FDP variation [(19.29 ± 18.67) mg/L,r was 0.556 and 0.460,respectively;P was 0.020 and 0.002,respectively].Conclusions The D-dimer and FDP levels are kept falling in PE patients after treatment,suggesting that the pulmonary artery embolus is being dissolved.

Objective:To investigate the correlation between serum concentration of vasohibin-1 (VASH-1) and urinary albumin creatinine ratio (UACR) in patients with type 2 diabetes mellitus (T2DM) and diabetic nephropathy.Methods:The clinical data of 196 patients with T2DM from February 2017 to December 2020 were analyzed retrospectively. According to whether diabetic nephropathy (DN) was combined, 33 patients without DN of T2DM were divided into the control group,and 163 patients with DN of T2DM were divided into the case group, and the case group was divided into four groups:normal albuminuria group (groupⅠ, UACR <30 mg/g, 21 cases),microalbuminuria group (groupⅡ, UACR ≥30-≤300 mg/g, 50 cases), clinical albuminuria group (group Ⅲ, UACR>300 mg/g, 43 cases), and clinical albuminuria hypertensive group (groupⅣ, UACR >300 mg/g with hypertension, 49 cases). Serum levels of VASH-1,C-reactive protein(CRP), erythrocyte sedimentation rate (ESR) and transforming growth factor β1 (TGF-β1) with other biochemical indicators were measured. T-test was used for comparison between measurement data groups in accordance with normal distribution, one-way ANOVA was used for comparison between multiple groups, q-test was used for pairwise comparison, and χ2 test was used for comparison between counting data groups. The influencing factors were analyzed by multivariate Logistic regression.Pearson correlation analysis was used to analyze the correlation between vash-1 and UACR. Results:UACR((1 175.9±120.4) mg/g), CRP((9.80±2.01) mg/L), ESR((20.61±2.20) mm/h),TGF-β1((16.75±2.05) μg/L), VASH-1((645.3±183.5) ng/L) in case group were higher than that in the control group((11.5±2.0) mg/g, (4.77±1.34) mg/L, (8.33±1.56) mm/h, (10.63±1.97) μg/L, (416.3±162.1) ng/L), and there were significant differences between the two groups ( t=123.39,13.76,30.54,15.75,6.66; all P<0.001). Multivariate logistic regression analysis showed that VASH-1 ( OR=1.881,95% CI 1.146-3.089), UACR( OR=1.511,95% CI 1.064-2.146), TGF-β1( OR=1.846,95% CI 1.135-3.001)were all risk factors for DN of T2DM ( P values were 0.009, 0.022 and 0.012). Serum VASH-1 ((693.5±201.4), (709.8±214.7) ng/L] in group Ⅲ and group Ⅳ were higher than those in group Ⅰ and group Ⅱ ((585.3±162.1), (632.9±165.5) ng/L). There was significant difference between the two groups ( F=129.46, P<0.001). The CRP ((7.08±1.36), (8.99±3.72), (10.58±3.48), (11.64±3.50) mg/L), ESR ((17.36±1.76), (19.05±4.12), (21.45±5.74), (22.69±9.13) mm/h) and TGF- β1 ((14.75±1.97), (16.50±1.90), (17.06±1.23), (18.39±1.46) μg/L) of groupⅠ, groupⅡ, groupⅢ and groupⅣ increased gradually, and there were significant differences between the four groups ( F values were 73.48, 156.61, 25.83; all P<0.001). Pearson correlation analysis showed that there was a significant positive correlation between VASH-1 and UACR ( r=0.532, P=0.008). Conclusion:The concentration of VASH-1 in serum of patients with T2DM complicated with DN increased with the increase of UACR. VASH-1 may become a new marker for predicting early DN of T2DM.

Objective To investigate the value of MR diffusion tensor imaging(DTI)in assessment of the microstructural changes of the trigeminal nerve,and analyze it's correlation with the degree of vascular compression. Methods Thirty-four patients with trigeminal neuralgia from November 2015 to April 2017 were retrospectively analyzed in this study.And they were treated by microvascular decompression(MVD). There were 11 cases of gradeⅠ,16 cases of gradeⅡand 7 cases of gradeⅢaccording to the severity of the contact between nerves and vessels during the operation. All of them were scanned with three dimensional time-of-flight(3D-TOF)sequences, three dimensional fast imaging employing steady state acquisition(3D-FIESTA)sequences and DTI before undergoing surgical decompression. According to the preoperative MR scans,the trigeminal nerves were divided into the healthy side without neurovascular contact (25 cases) and the healthy side with a neurovascular contact (9 cases).The DTI parameters of the trigeminal nerve,including the anisotropic fraction(FA)and the ADC values were obtained.Comparison of the FA and ADC values of the trigeminal nerve between the different stages of the affected side was performed with single factor analysis of variance, and the paired samples t test was used to compare the difference of FA and ADC values of bilateral trigeminal nerve. The difference of FA and ADC values between the asymptomatic side with or without vascular contact was compared with independent sample t test. Spearman correlation analysis was used to evaluate the correlation between DTI parameters and the degree of compression. Results The FA values of patients with grades Ⅰ,ⅡandⅢwere 0.311±0.009, 0.308±0.007 and 0.299±0.009 respectively,and there was significant difference among different levels(F=5.269,P<0.05).The ADC values of the three grades were(2.298 ± 0.309)×10-3,(2.214 ± 0.175)×10-3and (2.259 ± 0.248)×10-3mm2/s respectively, showing no statistically significant difference(F=0.402,P>0.05). The FA values of bilateral trigeminal nerves in healthy side without neurovascular contact and in healthy side with neurovascular contact were statistically significant (t=-32.528,-25.178,P<0.05). There was significant difference in the ADC value of bilateral trigeminal nerves in the group without neurovascular contact(t=2.162,P<0.05).There was no statistically significant difference in the ADC values of bilateral trigeminal nerves in the healthy side of the neurovascular contact group(P>0.05).There were no statistically significant differences in the FA and ADC values between the two groups on the healthy side of the trigeminal nerve(P>0.05).The FA value was negatively correlated with the degree of vascular compression (r=-0.453,P<0.05),while the ADC value was not correlated with the degree of vascular compression(P>0.05). Conclusion DTI imaging can be used to evaluate the degree of trigeminal nerve injury. More obvious vascular compression leads to lower FA value.
