Objective To study the relationship between C reactive protein ( CRP) and postoperative deliri-um of elderly patients after hip fracture , and to explore the possible mechanism of delirium .Methods A total of 186 elderly patients with hip fracture who received operation were included in the study .24h after operation,according to the patients'awareness of ICU fuzzy evaluation method ,the patients were divided into the delirium group and non delirium group .The levels of CRP and procalcitonin were detected and compared .Results The CRP levels in the de-lirium group and non delirium group were (207 ±86)mg/L,(87 ±42)mg/L,there was significant difference between two groups (t =2.427,P <0.01).The procalcitonin levels in the delirium group and non delirium group were (0.32 ±0.11)μg/L,(0.27 ±0.13)μg/L,the difference between the two groups was not significant (t=0.347,P>0.05).Conclusion CRP may be related with delirium.Inflammatory response without systemic infection may be one of the mechanisms of delirium .

Different maternal positions and movement are utilized gradually in clinic while today it appears that the majority of women in the world birth in supine position or lithotomy position. To know the current situation and progress of the studies concerning different maternal positions and movement during labour and to explore the current relevant problems in clinic. The search strategy was designed to identify the relevant literature. The search was limited to the last 20 years as current literature was sought. Thirty eight papers were identified as relevant and included in this literature review. The majority studies is concerning about the outcome of mother and fetus. There is no unitized clinical pathway currently, and the objects implemented are limited. There is no study related to the requirement of implementing different maternal positions and movement during labor in clinic and the effect of pelvic floor function after parturition. The positive effect of implementing different maternal positions and movement during labor can be sure for the process of parturition and the outcome of mother and baby. Childbirth in different maternal positions and movement is the trend in the future. Therefore, how to utilize different maternal positions and movement during labor well, it is still a huge challenge for medical staff. And more convincing studies and information are needed as evidence in clinic.

Radiation-induced lung injury (RILI) is a common complication after radiotherapy for lung cancer and alternative thoracic malignant tumors, while ferroptosis is a regulated cell death triggered by iron-dependent membrane lipid peroxidation. In this article, the relationship between RILI and ferroptosis was investigated from oxidative damage induced by reactive oxygen species, antioxidant network and iron homeostasis regulated by nuclear factor erythroid 2-related factor 2(Nrf2) as well as transforming growth factor involved in the inflammatory response, aiming to mitigate or inhibit the occurrence of RILI through regulating ferroptosis, thereby improving clinical prognosis of patients undergoing radiotherapy.

The antibacterial activity and mechanism of the antimicrobial peptide mutant Cbf-14-2 against NDM-1 carrying recombinant bacteria (E.coli BL21 (DE3)-NDM-1) was investigated in this study.The minimum inhibitory concentration (MIC),minimum bactericidal concentration (MBC) and killing curves (KCs) in vitro were determined by the broth microdilution method.Mice septicemia model was established by interaperitotoneal injection of E.coli BL21 (DE3)-NDM-1 to evaluate the antibacterial activity of this peptide in vivo.Results showed that Cbf-14-2 exhibited a potent antibacterial activity with MIC of 16 μg/mL and killed almost all recombinant bacteria within 120 min.Meanwhile,it significantly improved the survival rate of infected mice up to 70% with the decreasing of bacterial load in mice lung,liver,spleen and kidney.This powerful clearance ability of Cbf-14-2 against bacteria mainly related to its enhanced membrane penetration ability through neutralizing the negative charges and disrupting the integrity of the bacterial cell membrane.Therefore,Cbf-14-2 is expected to be a potential antimicrobial agent for the treatment of infection induced by multi-drug resistant bacteria,especially for the NDM-1carrying bacteria.

Objective To evaluate the effects of dexmedetomidine on perioperative pulmonary compliance and the expression of Toll?like recep?tor(TLR)?2 and TLR?4 in the peripheral blood during perioperative period in patients undergoing open colorectal cancer radical surgery. Meth?ods Twenty patients with colorectal cancer underwent elective general anesthesia,with ASA gradeⅠ?Ⅱand body mass index(BMI)<30 kg/m2, aged 30 to 68 years old,were enrolled for the study. They were randomly divided into control group(group C,n=10)and dexmedetomidine group (group D,n=10). In group D,dexmedetomidine was infused at a rate of 0.4μg·kg-1·h-1 from the beginning of surgery till 30 min before the end of surgery. The patients in group C received same manipulation as in group D except dexmedetomidine was replaced by normal saline. The mean ar?terial pressure(MAP)and heart rate(HR)were recorded before anesthesia induction(T0),30 min(T2),60 min(T3),and 90 min(T4)after the beginning of surgery,extubation(T6),and 3 min after extubation(T7). Airway pressure and lung dynamic compliance were recorded at T1?T7 time points,respectively. Vein blood samples were drawn to analyze the TLR?2,TLR?4 and tumor necrosis factorα(TNF?α)concentration at T0,T4,T7 and the day after operation(T8),respectively. Results Compared with group C,MAP and HR increased in group D at T6(P<0.05);lung dynamic compliance increased in group D at T4(P<0.05);TLR?2 and TLR?4 concentration in serum decreased in group D at T4, T7 and T8(P<0.05);TNF?αconcentration in serum decreased in group D at T4,T7 and T8(P<0.05). Conclusion Continuous infusion of 0.4μg·kg-1·h-1 dexmedetomidine can help to stabilize hemodynamics,relieve inflammatory stress response,maintain the relative stability of intra?operative hemodynamic parameters,and also can improve the pulmonary dynamic compliance of patients.

Objective To investigate the association of chromosome 8p copy number alteration (CNA) with postoperative survival of patients with hepatocellular carcinoma (HCC),and to screen for possible target genes in the survival-related CNA (s) in 8p.Methods 187 HCC patients were enrolled into the study,which included 66 patients whose follow-up data were available and the follow-up was 2.6 ~ 73.3 months.High-resolution Agilent 244K comparative genomic hybridization (CGH) and Affymetrix U133 Plus2.0 expression arrays were used to screen for CNAs and gene expression differences in 8p.The associations between CNAs in 8p and survival were analyzed using the log-rank test,Kaplan-Meier survival analysis and Cox proportional hazards models.The gene expression levels between the groups were compared by the Mann-Whitney U test.Results Copy number loss on 8p12 (31/66,47%) was significantly associated with reduced survival rate,and HCC patients with 8p12 loss had a 4.1-fold (95% CI =1.8 ~ 9.4,P < 0.05) increased hazard ratio (HR) for death from HCC,as compared to those without the loss.The mRNA expression levels of the 3 genes in 8p12,including TMEM66,DCTN6,and MAK16,were significantly decreased in HCCs with gene loss than in HCCs without the loss (all P < 0.05),and in non-tumorous liver tissues (all P < 0.05).Conclusion Loss of 8p12 is an independent prognostic marker of unfavorable survival for patients with HCC,and underexpression of genes TMEM66,DCTN6,and MAK16,owing to 8p12 loss,contributed to unfavorable prognosis.
