Vascular endothelial growth factor receptors ( VEGFR ) belong to the receptor-type tyrosine kinase ( RTK ) super family and play important roles in tumor angiogenesis.Abnormal activation of VEGFR results in several disorders including cancer.VEGFR-2 is the major signal transducer for angiogenesis, and therefore, it becomes a good target for the inhibition of tumor development and metastasis.Nowadays, the VEGFR-based antiangiogenic therapy becomes one of the most powerful clinical strategies for cancer treatment.In this review, small molecular VEGFR-2 inhibitors are classified according to their structural features, their biological activities and current statue are briefly introduced.

Objectives To investigate the risk factors of acute renal injury (acute kidney injury) in patients with acute left heart failure.Methods Clinical data of 188 patients with acute left heart failure who were admitted to our hospital were retrospectively analyzed.Logistic regression analysis was used to assess the risk factors for AKI.Results Among 188 patients with acute left heart failure,incidence of acute kidney injury was 33.51％.Univariate and Multivariable logistic regression analyses showed that the independent predictors of acute kidney injury were lower baseline eGFR (OR=4.294,P ＜ 0.001) and anemia (OR=3.573,P=0.006).Conclusions The incidence of acute left heart failure complicated with AKI was high.Basic state of renal function and anemia were the independent risk factors for AKI.

Objective To explore the relationship between physical growth of infants and family feeding be -havior.Methods Demographic information was collected from 516 objects.Height,weight,head circumference,chest circumference were measured and feeding behavior was evaluated using prospective observational study method . Results (1) Feeding behavior score was positively associated with infant physical development indicators ,the be-tween groups differences of infant age ,body weight,body length were statistically significant (P<0.05).(2)The re-sults of Pearson correlation analysis showed that weight , head circumference of infants at 18 months and length at 24 months were significantly correlated with feeding behavior score (P<0.05).(3)The analysis of feeding behavior factors found that food preparation was associated with weight infants at 18 months(P<0.05);behavior of infants and height,weight,head circumference,chest circumference of children in the 18 months of age were related(P<0.05);infant feeding environment in the 18-month-old was related with their height,weight,head circumference(P<0.05). Conclusion It is suggested that well family feeding pattern might be a certain stimulative role in young children ′s physical growth and development .

Objective To approach the diagnostic value of contrast-enhanced ultrasonography(CEUS)for the detection of traumatic laceration of pancreas. Methods Sixty cases of pancreatic traumatic model were made in twelve healthy swines after the animals were anesthetized and laparotomized. Then the conventional ultrasonography(US) and CEUS were performed in each case to diagnose the traumatic region,immediately. The results were compared with surgical findings. Results Among sixty injuries,the detection rate of conventional ultrasonography was 66. 7%,the detection rate of CEUS was 88.3%. Conclusions CEUS shows higher detection rate than conventional US in diagnosing pancreatic laceration,and it also can improve the diagnostic value of ultrasound for the detection of pancreatic laceration.

Objective To investigate the clinical features,early diagnosis and individualized treatment of renal hypophosphatemia and osteomalacia induced by adefovir dipivoxil (ADV) in patients with chronic hepatitis B (CHB).Methods Thirty-nine CHB or hepatitis B virus (HBV)-related cirrhosis patients of renal hypophosphatemia and osteomalacia induced by ADV were consecutively collected.The clinical features were analyzed and treatment outcome was followed up.Results The mean age of the 39 patients was 54 (27-71) years old.There were 26 male and 13 female patients,and 19 patients with cirrhosis.The mean ADV treatment duration was 69 (range 18-116) months,and 31 patients were treated for 36-96 months.The mean serum phosphate was 0.68 (0.42-0.79) mmol/L.Twenty-six cases developed renal hypophosphatemic osteomaolacia,of which 14 had bone pain and 19 had abnormally elevated alkaline phosphatase (ALP).Three patients had increased serum creatinine and 24 patients had decreased estimated glomerular filtration rate (eGFR).After individualized treatment,patients gained normal serum phosphate in mean of 2.0 (range 0.5-6.0) months,and had bone pain remission in the mean of 0.8 (range 0.2-1.0) month and bone pain disappeared in the mean of 1.5 (range 0.5-5.0) months.Function indices of liver and kidney were improved gradually,and the bone mineral density examination improved slowly.Conclusions CHB and HBV-related cirrhosis patients treated with longterm ADV could develop renal hypophosphatemia and hypophosphatemic osteomalacia,which is partially reversible.Monitoring serum phosphate,creatinine and cystatin C is necessary during long-term ADV therapy.After confirmed diagnosis,withdrawal or dosage reduction of ADV,and switch to telbivudine or entecavir should be considered.Meanwhile,serum phosphate and HBV DNA level should be monitored.

Objective To investigate the anti-fatigue activity of fermented grain-containing blueberry anthocyanins ( LANHE,LH) in mice.Methods Experiments were conducted in two phases .In the first phase , forty mice were randomly divided into four groups:control group(distilled water,dw) and three LH administration groups (8.75,17.5 and 35.08 ml/kg body mass).In the second phase, mice were randomly divided into two groups:high-dose LH group (35.08 ml/kg body mass) and control group (dw 35.08 ml/kg body mass).After four weeks, a forced swimming test was performed and the biochemical parameters related to fatigue were examined .Results and Conclusion The administration groups showed a significant increase of swimming time to exhaustion compared with the control group , especially the high-dose group ( P<0.001).There was no significant change in the blood lactate between the two groups , but at 20 min after swimming, the lactic acid(LA) contents of the high-dose group were lower than in the control group (P>0.05).LH could significantly increase the liver glycogen contents and decrease the serum contents (P<0.05).These data indicate that LH has anti-fatigue activity and can elevate the exercise tolerance in mice .

Objective To investigate the application and effect of aerobic exercise of pulmonary rehabilitation in patients with chronic obstructive pulmonary disease (COPD).Methods Ninety-four hospitalized patients with COPD from June 2011 to June 2012 were enrolled.The clinical curative effect and safety of aerobic exercise of pulmonary rehabilitation in patients with COPD were observed and compared.Results After 3 months treatment,first second forced expiratory volume (FEV1) and forced vital capacity (FVC) were increased compared with those before treatment [(3.25 ± 0.49) L vs.(2.59 ± 0.55) L,(1.95 ± 0.41) L vs.(1.44 ± 0.48) L],and there were significant differences (P ＜ 0.05).There was no significant difference in FEV1/FVC before and after treatment (P ＞ 0.05).After 3 months treatment,arterial partial pressure of oxygen and arterial oxygen saturation were increased compared with those before treatment [(87.61 ± 8.56) mm Hg(1 mm Hg =0.133 kPa) vs.(63.88 ± 8.79) mm Hg,0.9648 ±0.0449 vs.0.7632 ± 0.0477],partial pressure of arterial carbon dioxide was decreased compared with that before treatment [(30.57 ± 9.47) mm Hg vs.(49.23 ± 9.54) mm Hg],and there were significant differences (P ＜ 0.05).There was no signifi.cant difference in blood pressure and heart rate before and after treatment (P＞ 0.05).No obvious adverse reactions were observed.Conclusions The aerobic exercise of pulmonary rehabilitation can improve significantly lung function.It is safe and rehable,and has less adverse reaction in patients with COPD.It is worthy of promotion and use.

Objective: To explore the risk factors for hyperlipidemic acute pancreatitis (HTGP). Methods: The clincial data of 169 HTGP cases admitted in Capital Medical University Attached Xuanwu Hospital from September 2012 to December 2018 were retrospectively analyzed. Patients were divided into severe HTGP group (n=63) and mild or moderately severe HTGP group (n=106). Clinical data were compared between two groups and variables with statistically significance and clinical values were chosen and included for binary logistic regression to explore the independent risk factors for severe HTGP. Results: Severe HTGP patients′ heart beat and respiratory rate were significantly higher than moderately severe or mild HTGP cases, while the percentage of patients with previous AP history in severe HTGP group was obviously lower than moderately severe or mild HTGP cases. There were no statistically significant differences on other baseline data and previous history. Severe HTGP patients had significantly higher white blood cell, mean platelet volume, erythrocyte sedimentation rate, total protein, C-reaction protein on first day, C-reaction protein on third day, amylase, lipase, triacylglycerol, prothrombin time, D-dimer, fibrinogen, CTSI, APACHEⅡ score and Ranson score than those in moderately severe or mild HTGP cases; the lymphocyte count, albumin-globulin ratio, uric acid, apolipoprotein-A1, blood calcium, prothrombin activity were obviously lower than those in moderately severe or mild HTGP cases; and all the differences were statistically significant. Triglyceride and CRP on the first and third day, CTSI, APACHEⅡ score and Ranson score were included for binary logistic regression model, and the results showed that triglyceride on the first day (OR=1.08, 95% CI 1.02-1.14, P=0.01), C-reaction protein on the third day (OR=1.01, 95% CI 1.00-1.01, P<0.01), CTSI score(OR=1.51, 95% CI 1.06-2.13, P=0.02), APACHEⅡ score(OR=1.22, 95% CI 1.07-1.40, P<0.01)were the risk factors of severe HTGP, while triglyceride on the third day (OR=0.8, 95% CI 0.69-0.91, P=0.00)was the protective factor of severe HTGP. Conclusions Triglyceride on the first day, C-reaction protein on the third day, CTSI score and APACHEⅡ score were the risk factors of severe HTGP, which deserve special attention.

Objective: To explore the correlation of apolipoprotein levels with the severity of hyperlipidemic acute pancreatitis. Methods: Clinical date of 169 patients with hyperlipidemic acute pancreatitis (AP) admitted in our hospital from September 2012 to December 2018 were retrospectively analyzed. Apolipoprotein (Apo) AⅠ, Apo B, Apo B/Apo AⅠ ratio were compared among hyperlipidemic AP patients with different severity. Pearson correlation analysis was conducted to explore the correlation of Apo AⅠ, Apo B, Apo B/Apo AⅠ with Atlanta classification, CTSI score, APACHE-Ⅱscore, RANSON score and C-reaction protein level. The optimal cut-off point of apolipoproteins for predict the severe hyperlipidemic AP was determined by ROC curve. The local and systemic complications of pancreatitis patients with different Apo levels were compared with chi-square test. Results: There were no significant differences in general conditions among patients with severe AP (SAP), median-severe AP (MSAP) and mild AP (MAP). The Apo AⅠ levels of SAP [ (0.89±0.36) g/L] were lower than those of MSAP [(1.07±0.40)g/L, t=2.07, P=0.04] and MAP [(1.14±0.70) g/L, t=2.55, P=0.01]. Apo AⅠ was negatively correlated with Atlanta classification (r=-0.24, P<0.01). The optimal cut-off point of Apo A Ⅰ to predict SAP was 0.8 g/L, with the sensitivity of 0.877, specificity of 0.674 and Youden index of 0.55. The area under curve (AUC) was 0.623 (P<0.01). The proportions of SAP patients [52.94% (27/51) vs. 30.51%(36/118), χ²=7.66, P<0.01] and the patients of APACHE-Ⅱscore>8 [70.59%(36/51) vs. 55.08%(65/118), χ²=3.56, P=0.04] in patients with Apo AⅠ≤0.8 g/L were higher than those in patients with Apo AⅠ>0.8 g/L. Conclusion Apolipoprotein AⅠ level is negatively correlated with Atlanta classification and Apo AⅠ level can be used to predict severity of hyperlipidemic acute pancreatitis.
