Inflammation plays a key role in the formation of intracranial aneurysm. At present, the pathophysiological processes of intracranial aneurysms are mainly caused by both hemodynamic abnormalities and inflammation. Studies have shown that the inflammatory cels in the intracranial aneurysm wal are mainly mononuclear macrophages, and can secrete various effector molecules, weakening and destroying the structures of the vessel wal . Therefore, the research of the roles of differences played in different subtypes of macrophages and their effector molecules in the pathophysiological processes of intracranial aneurysms wil provide clues for exploring the pathogenesis of intracranial aneurysms and effective targeted therapy.

[Objective]To evaluate the efficacy of percutaneous kyphoplasty (PKP) in managing vertebral compression fractures due to osteoporosis(OVCF).[Method]Thirty-one OVCFs patients (46 vertebrae) undergoing PKP were retrospectively analyzed.In these patients,there were 9 males and 22 females who were from 61 to 78 years old with averaged 68 years,and the injured vertebrae were from T7 to L3.All the patients had plain X-rays and CT scan as well as MR images preoperatively.With all of the patients,local infiltration anesthesia were performed,20 were injected bilaterally while 11 unilaterally.Before and after operarion,the visual analogue scale (VAS) score was estimated and sagittal index(SI) as well as Cobb′s angle of the vertebrae were measured.The data were statistically analyzed with the method of paired t-test.[Result]The duration of follow up after operetion were 6 to 30 months with a mean of 18 months.The VAS score reduced from 8.7 before operation to 2.5 after operation (P

Purpose: To investigate the effectiveness of a structured death education program for older adults with chronic illness and their family caregivers. Methods: This study adopted two-group, nonrandomized quasi-experimental design. Patient–caregiver dyads in the intervention group (N = 40 dyads) engaged in the death education program at the bedside once a week for 5 weeks, and were compared with participants (N = 40 dyads) in the control group who received usual health education. The program consisted of five sessions based on the Interaction Model of Client Health Behavior. Death attitude, death competence, well-being, family function, and satisfaction were measured at baseline (T0), immediately after the intervention (T1), and 1 month later (T2). Data collection was conducted from July 30, 2019, to December 30, 2019. Results: The intention-to-treat analysis The intention-to-treat analysis of between groups at 1-month follow-up revealed that the intervention group had greater decreases in the fear of death (p=.002, 95% CI -2.53, -0.47; p<.001, 95% CI -3.61, -1.65) and death avoidance (p<.001, 95% CI -3.46, -1.84; p<.001, 95% CI -3.89, -2.43), had greater increases in the neutral acceptance (p=.032, 95% CI 0.05, 1.38;p<.001, 95% CI 0.99, 2.56) and death competence (p<.001, 95% CI 4.10, 8.01; p<.001, 95% CI 7.80, 12.11) in patients and caregivers, respectively. There were significant intergroup differences over time for patient well-being of (p<.001, 95% CI 3.06, 9.74) and satisfaction of (p<.001, 95% CI 2.01, 4.59). Results were consistent with the results from the sensitivity analysis. Conclusion This study demonstrated the feasibility and benefits of death education in hospitals and provided an implementation plan for nursing professionals. Nurses should consider providing death education for older adults with chronic diseases and their families to promote the development of palliative care and the quality of end-of-life.

Objective To evaluate the management of biliary complications (BC) following orthotopic liver transplantation (OLT). Methods From Feb 1999 to Feb 2004, 236 cases underwent OLT with end-to-end choledocho-choledochostomy. Biliary anastomosis was performed by intermittent suture with T tube placement in 96 cases, without T tube in 39 cases, by continuous suture in posterior wall and intermittent suture in anterior wall and without T tube in 101 cases. Results Thirty-two (13.3%) patients developed BC, with incidences in group 1, 2 and 3 of 17.7%, 15.4% and 7.9%, respectively. The incidence of hepatic hilar and/or intrahepatic bile duct strictures was 8.3%, 2.6% and 1.0%, respectively. BC incidence in group 3 significantly decreased. Twenty patients with biliary stricture underwent endoscopic and/or radiological interventions, and stricture resolution was achieved in 90% of patients with anastomotic strictures and 60% of patients with hepatic hilar and/or intrahepatic strictures. Conclusions Modified biliary tract reconstruction technique contributes to the decrease of BC. Endoscopic and/or radiological interventions should be used for non-ischemic anastomotic biliary strictures or simple hepatic hilar strictures.

BACKGROUND:The complex relationship between bone marrow mesenchymal stem cels and cancers severely limit the clinical application of mesenchymal stem cels. So it is urgent to study the role of mesenchymal stem cels in tumor growth and metastasis.
OBJECTIVE:To explore the effect of human bone marrow mesenchymal stem cels on epithelial mesenchymal transition in non-smal cel lung cancer A549 and PAa cels.
METHODS:The A549 and PAa cels were cultured with mesenchymal stem cel supernatant (mesenchymal stem cel conditioned medium, MSCs-CM). The celular morphology was observed under a microscope. The mRNA and protein expression of E-cadherin, N-cadherin, Vimentin, Slug, Snail, and Twist were determined by RT-PCR and western blot. Transwel and wound healing assay were used to detect the change of migration and metastatic ability.
RESULTS AND CONCLUSION:Compared with the control group, the celular morphology of experimental group showed mesenchymal-like changes. In response to MSCs-CM, there was decreased E-cadherin but increased N-cadherin, Vimentin and Slug, Snail, Twist at mRNA and protein levels compared with the control group (P < 0.05). The migration and metastatic abilities of the experimental group were also increased. So, human bone marrow mesenchymal stem cels can promote epithelial mesenchymal transition in A549 and PAa cels, and enhance the migration and metastatic abilities of A549 and PAa cels.

Objective To sum up the experience of application of artificial liver support system (ALSS) combined with liver transplantation(LT) in the treatment of end stage severe hepatitis.Methods Clinical data of 23 patients with end stage severe hepatitis receiving ALSS treatment prior to liver transplantation among 223 patients who underwent LT consecutively between April 1993 and December 2003 were analyzed retrospectively. Twenty three patients with end stage severe hepatitis received 58 courses of ALSS prior to liver transplantation. The 6 month survival rate was compared to those in non ALSS non LT group and non LT group.Results ALSS treatment facilitated improvement of liver function, endotoximia, and the tolerance to LT, thus provided a bridge time for attaining the donor liver. The total serum bilirubin level at LT was significantly lower than that before the first run of ALSS ( P

Objective To investigate the clinical value of Hangzhou Criteria in selection of patients with hepatocellular carcinoma(HCC)for living donor liver transplantation(LDLT)and their effects on recipient's post-transplant survival.Methods A retrospective analysis was conducted on 43 patients with HCC who underwent LDLT in our center.All of the recipients were classified into subgroups according to Milan Criteria,Up-to-Seven Criteria and Hangzhou Criteria,and post-transplant total survival rate and tumor-free survival rate were compared among the criteria.Results The number of patients within Hangzhou Criteria was 61.5 %(8/13)more than that within Milan Criteria and 23.5 %(4/17)more than that within Up-to-Seven Criteria.The 1-,and 3-years total survival rate and tumor-free survival rate of the recipients within Milan Criteria(n=13)were 100 %,80.0 % and 84.6 %,84.6 %,those of the recipients within Up-to-Seven Criteria(n=17)were 100 %,75.2 % and 87.5 %,81.2 %,and those of the recipients within Hangzhou Criteria(n=21)were 100 %,80.0 % and 89.5 %,84.2 %,respectively.There was no significant difference among the three criteria in total survival rate and tumor-free survival rate(P>0.05).Conclusion Hangzhou Criteria further enrolled more liver transplantation candidates without decline of total survival rate and tumor-free survival.It is a more effective selection of HCC recipients for LDLT.

Objective To analyze the clinical profile and short-term postoperative prognosis of mixed hepatocellular carcinoma and cholangiocarcinoma (mHCC-CC). Methods Clinical data of 17 mHCC-CC cases undergoing hepatectomy were retrospectively analyzed. Results Patients average age was 53 years (27～76 years).There were 11 males (64.7％) and 6 females.Ten patients (58.8％) were asymptomatic,twelve patients(70.6％ ) had positive serology for hepatitis B infection,serum AFP levels ＞25 ng/ml in 12 cases. Serum CA199 levels ≥ 37 U/ml in 4 cases. All patients underwent radical hepatectomy,including ＞ 1.5 cm safe margin and lymphadenectomy.The 6-,12-,and 18-months overall survival rate was 93.8％,86.5％ and 57.7％,respectively.The 100- and 200-day disease-free survival was 65.3％ and 43.5％.The median disease-free survival was 161 days. Conclusions mHCC-CC is difficult to diagnose preoperatively.The diagnosis depends on pathological examination.The main treatment was surgical resection.The prognosis of mixed primary liver cancer is poor and tends to recur early after hepatectomy.

Lung cancer is currently one of the most common malignant tumors in the world. The occurrence and development of lung cancer, especially non-small cell lung cancer (NSCLC), are closely related to the abnormal expression of long non-coding RNA (lncRNA). lncRNA with a transcript of more than 200 nucleotides is involved in chromatin modification, transcription activation, transcription interference and other regulatory processes, and has varying degrees of regulation on the proliferation, migration, and invasion of tumor cells. It is characterized by up-regulation or down-regulation of expression. At present, there are a large number of studies on lncRNA, because lncRNA has considerable application prospects in the diagnosis, clinical treatment, drug resistance research and prognosis evaluation of NSCLC. In this paper, the overview of lncRNA, the up-regulation or down-regulation of NSCLC-related lncRNA expression, NSCLC clinical treatment and drug-resistant lncRNA were summarized.
