For stage Ⅱ colon cancer patients after surgery,the benefit of adjuvant chemotherapy remains controversial.Several studies indicate that the patients with high-risk stage Ⅱ colon cancer can benefit from adjuvant chemotherapy after surgery.According to the clinical and pathological features,the stage Ⅱcolon cancer patients including T4 lesion,perforation,peritumoral lymphovascular invasion can benefit from the adjuvant chemotherapy of oxaliplatin.In the horizontal of molecular and genetic levels,the stage Ⅱ colon cancer patients can express high microsatellite instability (MSI-H) and cannot benefit from the chemotherapy of Fluorouracil.The guiding functions of 18q loss of heterozygosity (18q LOH),Cx43 and gene expression profiling in adjuvant chemotherapy are still unclear,and need further study.

Objective To explore the acute toxicity and LD 50 of Tripterygium Hypoglaucum (Levl) Hutch(THH) solution to provide information for safe clinical application. Methods After oral administration of THH solution in mice, the mortality and the physiological and pathological changes were observed. Results The LD 50 (95% confidence limit) of THH in male and female mice was 79 g/kg(69～89 g/kg) and 100 g/kg (90～112 g/kg), respectively. No marked pathological change of the organs was found. Conclusion According to the standard of grading of acute toxicity, THH solution belongs to the moderate class. Therefore, it is safe in clinical practice and has a wide application.

Number needed to treat (NNT) is a simple and effective index for clinical therapeutic effect assessment worldwide accepted in recent years. By calculation of absolute risk reduction (ARR) of classified variables, it made the effect estimate reflect objectively the therapeutic effect of an intervention. However, clinical application of this index was introduced rarely in Chinese literature. With the examples from some published clinical reports, the calculation of NNT and its 95% confidence interval were demonstrated in this paper, and its application was illustrated by some relevant terms explanation and Meta-analysis methods introduction.

Objective To observe the behavior changes and synaptic reconstruction of brain and the impact of gastrodin in rats with epilepysy induced by pentylenetetrazole.Methods Fifty Wistar rats in growth(50-70 g) were randomly divided into 5 groups:control group,Pentylenetetrazole (PTZ) group,gastrodin high dose group,gastrodin low dose group and sodium valproate group,each group had 10 rats.According to Racine classification,the behavior changes of rats and the frequency were recorded.Conventional method was adopt to perfuse cordis, fix and extract the brain,and the immunohistochemistry was used to detect synaptophysin(P38) expression in the temporal lobe and hippocampus of the brain after 4 weeks.Results 1.Four weeks after pentylenetetrazole ignited the growth period rats,the attack-level of each experimental group through comparison with each other,there was statistically significant difference(?2=35.83 P0.05).Conclusions There are mossy fiber sprouting and the formation of synaptic reconstruction in temporal lobe and hippocampus of the growth period rats repea-tedly ignited by pentylenetetrazole.Gastrodin may play a role in the formation of antiepileptic obviously,and through decreasing the expression of P38,which can inhibit the formation of synaptic reconstruction,as control seizures indirectly.

Objective To observe the concentration changes of plasma cortisol ( Cor ) and adrenocorticotropic hormone( ACTH) in preterm infants with respiratory failure receiving ventilation treatment. Methods The 30 preterm in-fants with respiratory failure requiring mechanical ventilation were selected as the preterm group with respiratory failure, and 32 full term infants with respiratory failure in need of mechanical ventilation were selected as the term infant group with respiratory failure, and 52 preterm infants( preterm control group) and 17 full term infants( term control group) were selected as controls. All the cases were chosen from Neonatal Intensive Care Unit of Anhui Province Children′s Hospital during January to December 2014. The levels of plasma Cor and ACTH were measured and analyzed. Results (1) Cor level:on the 3rd day, the level of plasma Cor in the preterm group with respiratory failure was lower than that in the term group with respiratory failure[262. 50(162. 00-332. 50) nmol/L vs 531. 00(244. 75-644. 00) nmol/L], and higher than those in the preterm control group[199. 50(49. 05-388. 95) nmol/L] and term control group[120. 00(43. 90-191. 00) nmol/L], the differences were statistically significant(all P<0. 05). On the 7th day, the level of plasma Cor in the preterm group with respiratory failure was lower than that in the term group with respiratory failure[128. 00(65. 85-244. 00) nmol/L vs 222. 00 (131. 50-377. 85) nmol/L], the difference was statistically significant(P<0. 05). (2) ACTH level:on the 3rd day, the level of ACTH in the preterm group with respiratory failure was higher than those in the other groups[38. 20(25. 18-76. 65) pmol/L vs 24. 60(19. 03-38. 20) pmol/L vs 22. 30(14. 40-40. 60) pmol/L vs 24. 20(13. 90-45. 65) pmol/L], the differences were statistically significant(P<0. 05). On the 7th day, the concentration of ACTH in the preterm group with respiratory failure was lower than those in the term group with respiratory failure[16. 55(12. 78-31. 80) pmol/L vs 29. 85(18. 23-54. 65) pmol/L], and there were statistical differences(P<0. 05). Conclusions The newborns with respiratory failure were in criti-cal stress, the level of plasma Cor in the preterm infants with respiratory failure was lower than that of the term infants with respiratory failure, while the level of ACTH in the former was higher than that in the latter. And when the stress disap-peared, both of the plasma Cor and ACTH recovered to the normal level.

Objective To study the expression of serum interleukin (IL )-6 and IL-10 in sepsis patients ,and their correlations with immune function .Methods A total of 56 patients with sepsis were divided into three groups ,including 18 patients in sepsis group ,21 patients in severe sepsis group ,17 patients in septic shock group .All the patients were also divided into survivor and death group according to whether they survived within 2 weeks .Other 30 healthy persons were selected in the control group .Serum IL-6 and IL-10 ,CD4+ /CD8+ were detected and compared .Results Serum IL-6 and IL-10 levels in the three sepsis groups were significantly higher than those in control group ,and with the severity aggravating ,these indicators increased .The level of serum IL-6 in sepsis patients was significantly reduced at the 3rd day ,while there was no difference on the serum IL-10 in severe sepsis group and septic shock group compared with that at admission(P>0 .05) .Compared with survivor group ,serum IL-6 and IL-10 levels on both admission and the 3rd in death groups increased significantly (P<0 .05) .CD4+ ,CD8+ ,CD4+ /CD8+ were negative related with serum IL-6 and IL-10 in both severe sepsis and septic shock group (P<0 .05) .Conclusion The expression of IL-6 and IL-10 in patients with sepsis are over-expressive ,and closely related with disease activity and immune function .

Objective To investigate the causes and therapeutic methods of compartment syndrome following radial artery cannulation in the left forearm.Methods The data(including puncture pin type,puncture frequency, onset time and INR) and therapeutic methods(including using manicol,cold compress,fasciotomy,dactylolysis and dermatoplasty) of 6 patients were retrospectively analyzed,which had compartment syndrome after radial artery can- nulation in the left forearm.Results The type of puncture pin and puncture frequency attributed to this disease to some extent.After therapy,4 patients recovered completely.2 patients underwent fasciotomy,and Volkmann syn- drome happened in 1 patient,dactylolysis happened in the other because of necrosis in the left thumb and finger.Con- clusion Compartment syndrome may be avoided by correct selection of puncture pin type and no repeated punctur- ing,and early diagnosis and therapy are important for fine prognosis.
