Objective To study Baizhu's inhibitory effect on S180 sarcoma growth and its effect on Bcl-2 expression in tumor-transfected mice. Methods S180 cells were subcutaneously injected into 60 healthy Kunming mice. Meanwhile the mice were dealt with MTX or Baizhu, separately; the weight of tumor was measured in the following two weeks; the expression of Bcl-2 was detected by RT-PCR. Results The tumor's weight in Baizhu group was lower than that in model group, but higher than in MTX group (P<0.05), but Baizhu's inhibition was not associated with its dose (P>0.05), and Baizhu's rate of tumor growth inhibition was lower than that of MTX. Compared with that in control group, Bcl-2 expression was lower in Baizhu group obviously. Conclusion Baizhu can inhibit tumor growth and serve as an adjuvant drug in tumor therapy.

Objective To investigate the risk factors of mild cognitive impairment (MCI) in patients with type 2 dia-betes (T2DM), and the clinical evidence for the early diagnosis and treatment thereof. Methods A total of 217 T2DM pa-tients were divided into T2DM with MCI group (n=92) and T2DM with normal cognitive function(NMCI) group (n=125). Mon-treal cognitive assessment scale (MoCA) and activities of daily living scale (ADL) were used to assess the functional status in two groups of patients. The general clinical data and biochemical indicators were obtained and compared in two groups. Re-sults There were statistical differences in age, smoking history, education status, high sensitive C reactive protein (hs-CRP), coronary heart disease, hypertension, glycated hemoglobin A1c (HbA1c) and T2DM history between two groups. Re-sults of univariate logistic regression analysis showed that old age, longer course of T2DM, smoking history, higher hs-CRP and HbA1c, complicated with coronary heart disease and hypertension were risk factors for T2DM with MCI, while the higher education status was a protective factor. Multiple logistic regression analysis showed that old age and longer T 2DM history were risk factors, and the higher education was a beneficial factor for T2DM with MCI. Conclusion Many risk factors may play a part in T2DM with MCI. Early detection and prompting medical attention may help prevent and decrease the preva-lence of MCI in patients with T2DM.

Objective To investigate the relationship between serum uric acid and traditional risk factors of coronary artery disease. Basic information was obtained by using questionnaire and measured for blood pressure , height ,weight. Venous blood was collected for detecting fasting plasma glucose ,serum lipid and uric acid. All data were analyzed with SPSS 20.0. Correlation analysis was used to assess the association of serum uric acid and traditional risk factors of coronary artery disease in patients with coronary artery disease. Results The mean value of serum uric acid in coronary artery disease is 6.3 mg/dL. The level of serum uric acid was significantly higher in male than that in female. Serum uric acid and body mass index(r = 0.137,P < 0.001),systolic blood pressure (r = 0.053,P = 0.025)and triglycerides(r = 0.188,P < 0.001)had a positive correlation. Serum uric acid was negatively correlated with high density lipoprotein cholesterol(r =-0.146,P < 0.001)and estimated glomerular filtration rate(r=-0.340,P<0.001). Serum uric acid was higher in patients with men,smoking,drinking,and chronic CAD. The serum uric acid level was lower in patients with exercise time more than 30 minutes than no movement or movement time less than 30 minutes. Conclusion Elevated serum uric acid were associated with body mass index,systolic blood pressure,triglyceride,high density lipoprotein cholesterol,estimated glomerular filtration rate,male,smoking,and chronic CAD.

Objective To investigate the epidemiological characteristics of incipient neonatal hyperbilirubinemia. Methods The clinical data of admitted neonates with hyperbilirubinemia were retrospectively analyzed from June 2012 to May 2013. Results Two hundred and eight-four neonates with hyperbilirubinemia were enrolled and the ratio of male:female was 1.51:1. For the causes of hyperbilirubinemia, the incidences of ABO hemolytic and sepsis were higher in term infants than those in preterm infants, and the incidences of pneumonia, necrotizing enterocolitis and intracranial hemorrhage were higher in preterm infants than those in term infants (P<0.05). Compared with the preterm infants, the term infants had jaundice appearance and peak at earlier time, shorter duration of jaundice, faster decline rate of jaundice, higher levels of albumin and indirect bilirubin at the peak of jaundice (P<0.01). In the term infants, the time of jaundice appearance and peak were earlier in hemolytic group than those in non-hemolytic group (P<0.05). In preterm infants, the peak of transcutaneous bilirubin was higher in hemolytic group than that in non-hemolytic group (P<0.05). Six cases with bilirubin encephalopathy had abnormalities cranial MRI imaging, and the MRI was not entirely consistent with the peak level of bilirubin. Conclusions There are clinical differences between hemolytic and non-hemolytic hyperbilirubinemia in both term and preterm infants.

ObjectiveTo discuss the relationships among spastic paralysis and motor function, balance function and other clinical variables after stroke.MethodsAssessed the clinical spastic index of hemiplegic lower limbs with CSI scale, motor function with Fugl-Meyer Assessment, and balance function with Berg Equilibrium Scale, respectively. And then analyzed the relationship between clinical spasm index with motor function, balance function of the hemiplegic lower limbs with Pearson correlation analysis. Finally, ascertained which was the most important factor affecting the clinical spasm index of spastic lower limbs with stepwise regression analysis.ResultsThere is negative correlation between clinical spasm index with motor function and balance function, respectively. Tendon reflex, muscular tension and clonus are the deciding factors to motor function(P<0.05) and balance function(P<0.05) of the hemiplegic lower limbs.ConclusionThe clinical spasm index of hemiplegic limbs can affect the recovery of motor function and balance function significantly. So, assessing and improving the clinical spasm index of paralytic lower limbs can optimize the rehabilitation program to stroke patients.
