Sepsis and septic shock are the major causes of death in intensive care units (ICUs) worldwide. A large amount of studies on their pathophysiology have revealed an imbalance in the inflammatory network leading to tissue damage, organ failure, and ultimately, death. Cytokines, proteases, lipid mediators, vasoactive peptides, and cell stress markers play key roles in pathophysiology of sepsis. Although anti-inflammatory mediators can neutralize the promoting role of pro-inflammatory mediators, but persistent immune regulation may cause host susceptibility to concurrent infections. Therefore, it is a great challenge to seek effective clinical therapy against sepsis. To understand the complicated interplay between pro- and anti-inflammatory agents in sepsis, and their interaction in signal transduction and immune regulation in sepsis constitute vital significance to the prevention and control of sepsis. Summarize the latest findings about mediators associated with sepsis and innate and adaptive immune system at home and abroad in recent years, and illustrate the impact of its effects on sepsis, which may lead to resolution of many unexplored queries in the future.

Objective To investigated the role of the autophagy lysosomal pathway in PD cells and the possible molecular mechanisms. Methods A dopaminergic neuronal injury model was induced by 6-OHDA in PC12 cells . Autophagosomes in PC12 cells were examined by transmission electronmicro-scopy( TEM ). The expression of LC3- Ⅱ , Cathepsin B were assayed by western blot analysis. Results TEM revealed that the autophagosomes were increased in PC12 cells after 6-OHDA treatment and appeared apoptosis. The LC3-Ⅱ (2h:52.57 ±2.27,4h:56.83 ±3.51,6h:73.43 ±5.41,12h:103.90 ±2.57,24h: 100.40 ±3.91 )and Cathepsin B expression ( model group: 113.80 ± 4.46; normal group 35.89 ± 3.40) were increased after 6-OH DA treatments (P ＜ 0.05 or P ＜ 0.01 ). Conclusion The results indicate that autophagy lysosome pathway is involved in 6-OHDA-induced cell death in PC12 cells.

Objective To investigate the nursing professional values of different nursing groups and probe into the influencing factors.Methods By cluster and stratified sampling,a total of 583 participants including nursing students and registered nurses were investigated by Nursing Professional Values Scale.Results Nursing students and registered nurses hold a higher level of nursing professional values.Nursing professional value scores of nursing students were significantly higher than registered nurses.There was statistical difference between different nursing groups.Working years and monthly income were important influencing factors.Conclusions Nursing educators and administers could choose effective methods according to the condition to improve nursing professional values.

Objective To study the spatial arrangement of mouse connecting tubules（CNT）and their transition to collecting duct system.Methods The renal tissues of three C57/BL/6J mice were fixed by perfusion and embedded in Epon 812.Totally 2 000 consecutive sections with the thickness of 2.5 μm were obtained from the renal surface to the papilla.The serial images under microscope were digitalized and aligned.Thirty eight CNT were traced with a series of computer programs.Results The CNT from long loop nephron ascended towards renal capsule and merged with 5 to 6 CNT from short loop nephrons to form the so-called arcade,while the latter or some of the CNT from the superficial cortex directly drained into the collecting duct in the superficial cortex.The lengths of CNT and the arcade ranged from 150 μm to 500 μm and 600 μm to 900 μm respectively.Conclusion The arcade or CNT drains into collecting duct only at superficial cortical level,which suggests that the reabsorption of the glomerular ultra-filtration in collecting ducts keeps unaffected when collecting duct runs through middle to deeper cortex.

Objective To investigate the intraoperative intraperitoneal chemotherapy security with raltitrexed in advanced colorectal cancer surgical operation.Methods Sixty patients with colorectal cancer undergone surgery were randomly divided into trial group (n =30) and control group (n =30) according to the random number table method.The trial group was given surgical operation plus with intraperitoneal chemotherapy with raltitrexed.The control group was given surgical operation plus with intraperitoneal saline perfusion.Theroutine blood test,liver and kidney functions,toxic side effects and complications in two groups before and after surgery were investigated.Results The white blood cells in trial group before and after surgery was (6.36 ± 2.63) × 109/L vs.(8.20 ± 2.08) × 109/L,with statistically significant difference (t =3.06,P ＜0.05).The ratio of absolute neutrophil count in trial group before and after surgery was 65.17％ ± 10.36％ vs.72.21％ ± 10.53％ (t =3.22,P ＜ 0.05).The platelets in trial group before and after surgery was (261.03 ±84.74) × 109/L vs.(228.47 ± 58.69) × 109/L (t =2.07,P ＜ 0.05).The white blood cells,the ratio of absolute neutrophil count and the platelets after surgery had no statistically significant differeuces between the two groups (P ＞0.05).The trial group had higher 1,2 level vomiting (60.00％ vs.23.33％;x2 =8.30,P ＜ 0.05),and nausea (30.00％ vs.6.67％;x2 =5.46,P ＜ 0.05) incidence rates,but there was no statistically significant difference in other toxic side effects (P ＞ 0.05).The major complications post operation included intestinal obstruction,incision infection,abdominal cavity bleeding,and anastomotic fistula.There were equivalent complications in two groups (6.67％ vs.3.33％,x2 =0.35,P ＞0.05;10.00％ vs.6.67％,x2 =0.22,P＞0.05;0 vs.0;3.33％ vs.0,P＞0.05).Conclusion For patients with advanced colorectal cancer,intraoperative intraperitoneal chemotherapy with raltitrexed is safe and feasible,and the adverse reactions can be tolerated without increasing postoperative complications.
