Objective To explore the relationship of the presence and severity of anxiety and depression with the increased inflammatory activity,as marked by the serum levels of high sensitivity C reactive protein(hs-CRP)after acute coronary syndrome(ACS).Methods Serum hs-CRP levels were measured in 647 ACS patients within 36 hours after onset of event.Depression and anxiety were evaluated by self-reporting standardized questionnaire,using a validated Chinese version of Hospital Anxiety and Depression Scale(HADS)(14 items)within 7 days.Results In ACS patients,serum levels of hs-CRP(mg/L)were lower in those with anxiety than those in control group[(10.43?3.55)mg/L vs(13.19?4.90)mg/L,P0.05].Conclusion Presence and severity of depression is associated with increased activity of inflammation in patients with ACS;however,anxiety does not have such an association with inflammation in patients with ACS.

Objective:To evaluate the toxic effect of 3 different gingival retraction cords.Methods:DMEMextraction of DL-adren-aline HCl,aluminium sulphate and non-drug retraction cords with the extraction time of 5,10,15 and 30 min were respectively pre-pared and were used to culture human gingival fibroblasts(HGFs)in vitro respectively.Cell proliferation was tested by MTT assay. Cell apoptosis was examined by Annexin/PI method.Results:The 3 gingival retraction cord extractions inhibited the roliferation,pro-moted the apoptosis of HGFs(P <0.05),the effects were related to the extraction time.Conclusion:The 3 retraction cords have time-dependant cytotoxity.

Objective To observe the effects of berberine on neuralogical function,serum oxidized low density lipoprotein(ox-LDL),and matrix metalloproteinases-9(MMP-9) in patients with acute cerebral infarction.Methods Ninety-two patients with acute cerebral infarction were randomly divided into treatment group and control group (n=46).Control group received routine treatment,while treatment group was given 0.3 g of berberine three times a day besides routine treatment for 14 days.In both groups,decubitus venous blood was harvested before,7 and 14 days after treatment.Serum ox-LDL and MMP-9 were determined with enzyme-linked immunosorbent assay (ELISA).Before and 7 and 14 days after treatment,the neural function defect was graded by the US National Institutes of health stroke scale (NIHSS) and the modified Rankin scale (mRS).Results The neurological function was improved significantly in 7 and 14 days after the treatment for both two groups according to NIHSS and mRS,and the difference between treatment group and control group was statistically significant (P<0.05).After treatment,ox-LDL and MMP-9 declined significantly in both groups,and were lower in treatment group than in control group (all P<0.05).Conclusion Berberine significantly reduces ox-LDL and MMP-9 levels in patients with acute cerebral infarction and improves the degree of neurological function deficit.

Objective:To investigate the status quo of intravenous (IV) infusion device selection among hospitalized children and provide direction for improving practices related to the selection of infusion devices.Methods:A total of 1 306 hospitalized children undergoing IV infusion treatment in 11 clinical departments of Children's Hospital of Fudan University in June 2021 were selected by convenience sampling. A self-developed data collection form for the selection of IV infusion devices in hospitalized children and criteria for the appropriateness of IV infusion device selection were used to survey and evaluate the appropriateness of IV infusion device selection among these children.Results:IV infusion devices were found to have been appropriately selected in 1 137 of the 1 306 children, while these devices were inappropriately selected in 169 children. The inappropriate selection was primarily due to the improper choice of peripheral intravenous catheters (PIVC), with 155 cases involving the administration of non-peripheral compatible medications through PIVC. No significant statistical difference was found in the appropriateness of IV infusion device selection between the infant group and the child and adolescent group ( P>0.05). Significant differences were observed in the appropriateness of IV infusion device selection based on different physicochemical properties of medications and the duration of therapy ( P<0.01) . Conclusions:The standardization of IV infusion device selection among hospitalized children needs improvement. It is urgent to apply evidence from the Clinical Practice Evidence- Based Guidelines for Pediatric Intravenous Therapy regarding recommendations for IV infusion device selection, to initiate evidence application projects, and to standardize the selection of IV infusion devices.

Objective To assess the impact of ultrasound-guided fascia iliaca compartment block on major cardiovascular events and postoperative prognosis in patients with lower limb aortoiliac occlusive disease(ASO).Methods This study was a retrospective study including 353 patients with lower limb arterial reconstruction surgery for ASO at Xiamen Hospital Affiliated to Zhongshan Hospital of Fudan University from January 2018 to January 2022.Patients were divided into two groups based on different anesthesia:the group receiving ultrasound-guided fascia iliaca block combined with sciatic nerve block(Group B)and the group receiving monitored anesthesia care(MAC)(Group M).The primary outcome was the occurrence of major adverse cardiovascular events after lower limb arterial reconstruction surgery in ASO patients.The secondary outcomes included the incidence of non-cardiac postoperative myocardial injury,postoperative amputation,and other adverse reactions such as postoperative delirium,nausea,and vomiting as well as postoperative laboratory indicators.By using propensity score matching to balance baseline characteristics before surgery,the impact of different anesthesia methods on the occurrence of MACE and prognosis after surgery in ASO patients was analyzed.Results After propensity score matching,the incidence of MACE in Group B was lower compared with Group M(10%vs.3.4%,P=0.038);The incidence of MINS in Group B(33%vs.25%,P=0.200);The amputation rate of Group B(4.2%vs.3.4%,P＞0.99);The incidence of complications in Group B was(6.8%vs.4.2%,P=0.39);There was no statistically significant differ-ence in postoperative laboratory indicators between the two groups(P＞0.05).Multivariate analysis showed that nerve block(OR=0.25,95%CI:0.05～0.93),postoperative HBG(OR=0.95,95%CI:0.91～0.99)were in-dependent factors in reducing the incidence of MACE.Conclusion Ultrasound-guidance fascia iliaca compartment block and sciatic nerve block could reduce the risk of major adverse cardiovascular events in patients undergoing lower limb arterial revascularization surgery.
