AIM: To construct a lentiviral vector harboring RNAi sequence targeting human annexin A2 (ANX A2) and to investigate the functions of ANX A2 in antiphospholipid antibody (APL)-induced tissue factor (TF) expression in monocytes. METHODS: Four different short hairpin RNAs (shRNA) targeting ANX A2 gene were constructed and cloned into the pGCSIL-GFP vector. After identification with PCR and sequencing, the effective interference sequence was further determined by Western blotting analysis. The recombinant lentivirus LV-RNAi-ANX A2 harvested from 293T cells was transferred into THP-1 cells and the ANX A2 mRNA and protein expression on THP-1 cells were examined. The transferred-THP-1 cells were stimulated by APL/β_2GPI compound, and the TF mRNA and TF activity was assayed. RESULTS: The RNAi sequences targeting the human ANX A2 gene were successfully inserted into the lentiviral vector and the high-performance RNA interference sequence was sieved out. The recombinant lentivirus was harvested from 293T cells with a viral titer of 3×10~(12) TU/L. THP-1 cells infected with LV-RNAi-ANX A2 showed almost lockout of ANX A2 both at mRNA and protein levels. The TF expression was also significantly decreased in the transferred-THP-1 cells induced by APL/β_2GPI compound. CONCLUSION: The lentiviral vector constructed in the present study blocks the ANX A2 expression in THP-1 cells and further inhibits the TF expression induced by APL/β_2GPI compound, which indicates that ANX A2 do play an important role in APL-induced TF expression on monocytes.

Objective To compare the effects of pulse high-volume hemofiltration (PHVHF) and continuous veno-venous hemofiltration (CVVH) on severe acute panceatitis (SAP). Method From January 2005 to December 2009, a total of 38 patients with SAP were randomly(random number) divided into PHVHF group ( n = 18)and CVVH group ( n = 20). After hemofiltration for 72 hours, clinical symptoms, APACHE Ⅱ score, biochemical changes and mortality were observed. The levels of TNF-α, IL-6, and IL-10 in plasma were assayed by using ELISA before and after treatment. The doses of dopamine used in shock patients were also observed. Measurement data were expressed in(-x) ± s, and t-test was used for comparison between two groups. Results In both groups ,symptoms were markedly improved after treatment. The APACHE Ⅱ score, serum amylase, creatinine, and white blood cell count were decreased ( P < 0.05). Besides, hypoxemia and acidosis were corrected, and the PHVHF group was superior to the CVVH group especially in heart rate, breathing and APACHE Ⅱ score ( P < 0. 05).The levels of TNF-α, IL-6 and IL-10 decreased in both groups ( P < 0.05), and the PHVHF group was superior to the CVVH group ( P < 0. 01 ). The doses of dopamine used in shock patients also decreased in both groups ( P <0. 01 ), and they decreased more in PHVHF group than in CVVH group ( P < 0.05). The mortality was 11.1%in PHVHF group and 25 % in CVVH group. Conclusions PHVHF is obviously superior to CVVH in the treatment of SAP, and can serve as an important adjuvant therapy for SAP, stabilizing the hemodynamics and reducing the levels of pro-inflammatory factors and mortality.

Objective To retrospectively study the risk factors of aortic arch calcificationand its influence on the survival prognosis of maintenance peritoneal dialysis patients. Methods One hundred seventy-seven cases of maintenance peritoneal dialysis patients were enrolled, including 66 cases of aortic arch calcification cases. Their general dialysis data were collected for the evaluation of dialysis adequacy and residual renal function, and their chest X-rays were recorded to assess the degree of aortic arch calcification. The two variables Logistics regression was used to analyze independent risk factors of aortic arch calcification; Kaplan-Meier analysis was used to analyze the influence on prognosis of dialysis patients; and multivariate COX regression was employed to analyze independent risk factors of death in dialysis patients. Results Among the 177 selected cases of peritoneal dialysis patients, 66 cases (37.29%) presented with aortic arch calcification. Elevated serum phosphorus was an independent risk factor of aortic arch calcification (OR=54.69 ,95%CI:10.01-298.65, P<0.01). The probability of survival in patients with mild and moderate (severe) calcification of aortic arch was less than those without calcification. Moderate (severe) calcification of aortic arch was the independent risk factor of all-cause mortality and cardiovascular disease mortality, whose hazard ratios in patients with calcification were 3.779 times and 5.636 times of those in patients without calcification respectively. Conclusions Hyperphosphatemia is an independent risk factor promoting the development of calcification of aortic arch. The probability of survival in patients with mild and moderate (severe) calcification of aortic arch is less than those without calcification; moderate (severe) calcification of aortic arch is the independent risk factor of all-cause mortality and cardiovascular disease mortality.

Objective To investigate the protective effects and underlying mechanisms of Liuwei Dihuang Glucoside(LW-AFC)against fear sensitization induced by traumatic stress.Methods Mice were divided into naive,control,stressed and LW-AFC administration groups.The LW-AFC treated group received LW-AFC(1.6 g/kg daily)via oral gavage for two weeks following exposure to traumatic stress.The non-associative memory dependent fear sensitization responses in mice subjected to trauma were investigated,including behavior in novel environments,social interaction,and observational fear tests.Z-score normalization method was employed to integrate and assess multiple behavioral variables such as travel distance,freezing time,and corner time,and comprehensively examined fear sensitization behaviors across the groups.Additionally,serum concentrations of adrenocorticotropic hormone,corticosterone,aldosterone,renin,angiotensin Ⅱ,and aldosterone were measured using ELISA.Results Compared to the control group,stressed mice exhibited significantly reduced travel distance(P<0.0001)and increased freezing time(P<0.0001)in the new context test.Integrated Z-scores indicated a significant increase in fear behavior among stressed mice during the new context test(P<0.0001).In the social interaction test,stressed mice demonstrated significantly reduced travel distance(P<0.0001),increased freezing time(P<0.0001),increased corner time(P<0.05),and higher integrated Z-scores(P<0.0001).In the observational fear test,stressed mice showed significantly reduced travel distance(P<0.05),increased freezing time(P<0.001),increased corner time(P<0.05),and higher integrated Z-scores(P<0.0001).Compared to the stressed group,mice in the LW-AFC treated group displayed trends toward improvement in travel distance,freezing time,corner time,and integrated Z-scores in the new context tests,albeit without statistical significance.In the social interaction test,the LW-AFC treated group exhibited a significant reduction in freezing time(P<0.05)and integrated Z-scores(P<0.05).In the observational fear test,the LW-AFC treated group showed a significant reduction in freezing time(P<0.05)and integrated Z-scores(P<0.01).Compared to the naive group,control and stressed groups exhibited an increased trend in renin and aldosterone levels after the fear sensitization test.Although there were no significant differences between stressed and control groups,renin and aldosterone levels significantly increased between stressed and naive groups(P<0.05,P<0.05).Following LW-AFC treatment,serum renin levels showed no significant change,while aldosterone levels significantly decreased(P<0.05).Conclusion Stressed mice exhibited significant fear sensitization behavior in new context,social interaction,and observational fear tests,possibly associated with partial activation of the renin-angiotensin-aldosterone system(RAAS)system.LW-AFC treatment significantly mitigated fear sensitization behavior of stressed mice in social interaction and observational fear test,potentially due to its regulatory effects on the RAAS system in mice subjected to traumatic stress.
