Radiation-induced cognitive impairment is hypothesized to occur because of dynamic interactions be -tween multiple cell types, including astrocytes, endothelial cells, microglia, neurons, and oligodendrocytes.Cur-rent researche indicates that radiation-induced changes include the decrease in hippocampus neurogenesis , altera-tions of neuronal functions , particularly synaptic plasticity , as well as the elevation of neuroinflammatory cytokines .

Objective To investigate the effect of Danzhijiangtang capsule on serum,fat in type 2 diabetic rats.Methods The model of type 2 diabetes mellitus rats were established by injecting small does streptozotocin(STZ)into abdomen and feeding high sucrose-fat diet.All the rats were divided randomly into five groups.The level of blood glucose,serum insulin,insulin sensitivity index,blood fat(triglyceride, cholesterol,high-density lipoprotein,low-density lipoprotein),free fatty acid after treated were examined. Results Danzhijiangtang capsule could decrease the level of blood fat.Conclusion Danzhijiangtang capsule could improve the blood fat in type 2 diabetic rats.

According to the onset age, a total of 5 674 outpatients with gout admitted in the affiliated hospital of Qingdao University from January 2011 to January 2016 were divided into youth group (≤44 years, n=3 058), middle age group (45~64 years, n=2 101), and elderly group (≥65 years, n=515).Their clinical and biochemical characteristics were analyzed.The results showed that the proportion of gout in the males in three groups was higher than that in the females.The proportions of gout in male youth, middle age, and elderly groups were 98.1%, 93.4%, and 83.1%, respectively.The proportion of gout in females increased with age.The proportion of gout family history in youth group was higher than that in middle age and elderly groups(P<0.05).The proportions of hypertension and impaired fasting glucose(IFG) in elderly group were higher than those in youth and middle age groups (P<0.05), with lower proportions of hypertriglyceride and obesity (P<0.05).The levels of systolic blood pressure, blood urea nitrogen, creatinine in elderly group were increased compared with youth and middle age groups (P<0.05) while the levels of uric acid and triglyceride were decreased (P<0.05), with higher ratio of renal dysfunction (P<0.05).There were no differences in tophus and kidney calculi among three groups (P>0.05).The distributions of the onset joint among three groups revealed statistical difference(P<0.05), but the first plantar toe joint was mostly involved in each group.These results suggest that the clinical characteristics of patients with gout at different onset ages are not identical, should be treated differently.

Objective To assess the efficacy of rociverine tablets combined with imrecoxib tablets and comfortable nursing in the control of bladder spasm after transurethral laser resection of prostate.Methods According to the digital table,120 patients who diagnosed as benign prostate hyperplasia (BPH) were randomly divided into four groups.The patients in combined drug group (group A) were administered rociverine tablets(10mg tid) and imrecoxib tablets (100mg bid) from the day of surgery to the day of catheter removal.The patients in rociverine tablets group (group B) were treated with rociverine tablets (10rag tid),and the patients in imrecoxib tablets group (group C) were administered imrecoxib (100mg bid) from the day of surgery to the day of catheter removal.The patients in group D were administered indometacin suppositories in anus when they felt pain.All patients were given comfortable nursing.The frequency and duration of bladder spasm,the time of bladder irrigation,time needed for washing solution to turn clear,and the time of catheter indwelling in the four groups were observed and compared.Results Compared with group D,group A,group B and group C all had statistically significant differences in the frequency and duration of bladder spasm,the time of bladder irrigation,time needed for washing solution to turn clear,and the time of catheter indwelling (Fa =9.469,Fb =13.443,Fo =12.157,Fd =26.609,Fe =33.717,Ff =30.524,Fs =100.836,Fh =89.985,P3 ＜ 0.001).These parameters were lower in group A than those in group B and group C,and the differences were statistically significant (P1 =0.030,0.002,0.012,0.003,＜ 0.001,＜ 0.001,＜ 0.001,＜ 0.001;P2 =0.030,0.004,0.035,0.001,＜ 0.001,＜ 0.001,＜ 0.001,＜ 0.001).There were no statistically significant differences between group B and group C (all P4 ＞ 0.05).Conclusion Rociverine tablets combinined with imrecoxib tablets for the prevention and treatment of bladder spasm after transurethral laser resection of prostate was effective,which was worthy of clinic application.

Objective To investigate the effects of preconditioning with different concentrations of sevoflurane on the expression of Toll-like receptor 4 (TLR4) in rats with acute lung injury (ALI) induced by lipopolysaccharide (LPS).Methods Thirty adult male Sprague-Dawlcy rats,wcighing 200-250 g,were randomly divided into 5 groups (n =6 each):normal saline group (group NS),group ALI,and preconditioning with different concentrations of sevoflurane groups (groups S1-3).ALI was induced by intratracheal instillation of LPS 5 mg/kg.Groups S1-3 inhaled 1.2％,2.4 ％ and 4.8 ％ sevoflurane for 30 min respectively,and ALI was induced 30 min later.The rats were sacrificed at 12 h after administration of LPS or normal saline and lungs were removed for microscopic examination and for determination of TLR4 mRNA and protein expression in lung tissues and concentrations of TNF-α and IL-1β in broncho-alveolar lavage fluid (BALF).W/D lung weight ratio was calculated.Results Compared with group NS,W/D lung weight ratio and concentrations of TNF-a and IL-1β in BALF were significantly increased and the expression of TLR4 mRNA and protein was up-regulated in groups ALI and S1-3 (P ＜ 0.01).Compared with group ALI,the parameters mentioned above were significantly decreased in groups S2 and S3,and the concentrations of TNF-α and IL-1 β in BALF were significantly decreased and the expression of TLR4 mRNA was down-regulated in group S1 (P ＜ 0.05 or 0.01).The parameters mentioned above were significantly lower in groups S2 and S3 than in group S1 (P ＜ 0.05).The pathologic changes were significantly attenuated in groups S1-3 compared with group ALI.Conclusion Preconditioning with sevoflurane can concentration-dependently reduce LPS-induced ALI in rats through inhibiting the up-regulation of TLR4 expression in lung tissues and reducing the inflammatory response.

Objective The effects of TPT on the induction of apoptosis of leukemia cells and the regulation of c-myc in mRNA and protein level. Methods RT-PCR method was adopted to examine the expressions of the genes and immune histochemistry for the proteins of c-myc in HL-60 cells treated with TPT of optimal concentration and time. Results After HL-60 cells by TPT of 0.15 μmol/L for 12 h, the expression of c-myc mRNA decreased markedly assayed by RT-PCR. There was a significant difference between the TPT group and the control group(0.17±0.03 vs 1.11±0.25, P <0.05), expressive c-myc protein decreased assayed by evidently immunohistochemistry. The percentage of positive cells expressing c-myc protein was a significant difference between the TPT treated group and the control group (19.67 % vs 68.33 %, P<0.05). Conclusion TPT down-regulates endogenic c-myc mRNA and c-myc protein in HL-60 cells.
