Objective: To understand and solve the problems in health education in intravenous infusion among elderly patients with cardiovascular disease.Methods: An investigation was conducted with a self-designed questionnaire among 127 elderly cardiovascular disease patients receiving intravenous infusion,with the purpose of finding out specific problems concerning the education so as to adopt effective countermeasures.Results: Among the patients investigated,88.9% considered the contents of the health education to be too simple,50% thought of the nurses as lacking in initiative,19.8% deemed the nurses short of expertise,and 41.3% thought that supervision had to be emphasized in the management of health education.Conclusion: Systematic,comprehensive and scientific health education in intravenous infusion plays an important role in ensuring the safety and improving the satisfaction rate of intravenous infusion among elderly patients with cardiovascular disease.

After the tissue injuries appear,bone marrow mesenohymal stem cells(MSCs)migrate to the lesion place against the chemokine concentration gradient and produce natural compensatory repair by differentiation of the injured cells,immunological regulation and paracrine of various cytokines,such as hepatocyte growth factor(HGF).HGF is one of the important chemokine factors of MSCs.It can inhibit proliferation of MSCs and induce MSCs into hepatocytes and epithelial cells.However,the mechanisms of MSCs on the injured tissue repairing are complicated,and the underlying mechanism consists of homing to the injured lesion,correct oriented differentiation of local micrcenvironment and in inhibition on the host immunity.With the deeperresearch,the mechanism of reparative process MSCs acting on damaged tissue will be elucidated gradually.It may be helpful for the instruction of the clinical treatment to engraft MSCs which are modified with effective genes and to enhance the ability of ceil engraftment.

Objective Meningovascular syphilis is the intima inflammation of blood vessels caused by the syphilitic infec-tion, which is associated with the occurrence of ischemic stroke.The study analyzed the clinical, imaging features and prognosis for meningovascular syphilis so as to improve its diagnosis and treatment. Methods 14 patients diagnosed with meningovascular syphilis were collected prospectively from December 2007 to March 2015 in the neurological department of Jinling Hospital.The patients were followed for a period of 21.5(range 10.2~37.9)months,and the prognosis were evaluated. Results Patients with meningovascular syphilis presented with dizziness, hemiplegia, hemidysesthesia and cognitive decline.Lesions showed multiple, scattered on MR ima-ging, intracranial vascular stenosis was seen in the CTA/MRA, and the laboratory examination had characteristic changes.With a large dose and sufficient courses of penicillin treatment, meningovascular syphilis may hopefully get predominant effects.78.57%patients got good prognosis(modified Rankin Scale ,mRS≤2)at 3 months and 85.71% patients got goodlong-term prognosis(mRS≤2). Conclusion Meningovascular syphilis was usually presented as acute onset, lacks the specific clinical and neuroimaging manifesta-tions.Most patients has favourable prognosis after treatment of syphilis with full course of penicillin.

Objective:To study and analyze the application effect of risk prevention and quality control nursing in peritoneal dialysis patients with renal failure.Methods:From January to December 2019, a total of 86 patients with renal failure in the Affiliated Hospital of Jining Medical College were recruited as the research objects by convenient sampling method. All the objects were divided into the observation group (43 cases) and the control group (43 cases) by the random number table method. The control group was treated with traditional risk prevention and control nursing, while the observation group was treated with risk prevention and control quality control nursing. The changes of albumin, hemoglobin, creatinine, blood urea nitrogen were compared between the two groups before and after intervention, and the incidence of complications such as peritonitis, catheter outlet infection, water retention and hypokalemia were compared between the two groups.Results:After the intervention, the albumin and hemoglobin levels of the observation group were higher than those of the control group, and the levels of creatinine and urea nitrogen in the observation group were lower than those in the control group, and the differences were statistically significant ( P<0.01) . During the intervention, the complication rate of the observation group was 23.26% (10/43) , which was lower than 46.51% (20/43) of the control group, and the difference was statistically significant ( P<0.05) . Conclusions:Risk prevention and quality control nursing in peritoneal dialysis patients with renal failure can improve renal function and reduce the occurrence of complications.

Objective:To compare the clinical features between chronic active Epstein-Barr virus infection(CAEBV) and infectious mononucleosis(IM)in adult patients.Methods:Clinical data from 56 adult IM patients and 14 adult CAEBV patients admitted in the First Affiliated Hospital of Nanjing Medical University during January 2011 to December 2019 were enrolled. Clinical manifestations, laboratory indicators, treatment and outcomes were compared between two groups. Chi-square test and Mann-whitney U test were used to analyze data. Results:The average age of CAEBV patients was higher than that of IM patients [36.0(23.8, 50.5)years vs. 19.0(17.3, 22.8) years; U=90.0, P<0.05]. The symptoms of sore throat, throat congestion, tonsilla enlargement and lymphadenopathy in IM group were more common than those in CAEBV group( χ2=14.088, 16.875, 31.855 and 10.938, all P<0.01). However, the incidence of pulmonary infection, sleepiness/dysphoria and splenomegaly in CAEBV group were significantly higher than those in IM group( χ2=17.217, 5.809 and 6.254, P<0.05 or <0.01). The white blood cell counts, hemoglobin levels, platelet counts, alanine aminotransferase(ALT) and albumin in CAEBV group were significantly lower than those in IM group( U=47.0, 49.5, 158.5, 173.0 and 263.5, all P<0.01). The levels of neutrophil ratio, C-reactive protein, serum ferritin and EBV DNA load in CAEBV group were significantly higher than those in IM group( U=145.0, 140.0, 128.5 and 115.0, P<0.05 or <0.01). The proportions of CD3 + T cell counts and CD8 + T cell counts in CAEBV group were significantly lower compared to those in IM group( U=42.0 and 24.5, P<0.01); the proportions of CD4 + T cell counts, the CD4 + T/CD8 + T cell counts ratio and B lymphocytes in CAEBV group were significantly higher compared to those in IM group( U=29.0, 23.5 and 34.5, P<0.01). Fifty-six IM patients were all cured and discharged from hospital. In CAEBV group, 8 cases died, 3 cases were improved and 3 cases lost follow-up. Conclusions:Patients with IM represent a favorable prognosis, while the prognosis of CAEBV is relatively poor and complication with HLH may occur. For older patients with EBV infection complicated with pulmonary infection, lethargy/irritability, attention should be paid to monitor blood routine, liver function, serum EBV DNA load and peripheral blood lymphocyte subsets.

Objective To study the association of single nucleotide polymorphism (SNP) of the protein tyrosine phosphatase-1B (PTP-1B) gene with type 2 diabetes mellitus and obesity in Chinese. Methods SNPs in the PTP-1B gene were detected by direct sequencing to PCR products, and the detected SNPs were genotyped in case-spouse samples with the technique of fluorescence real-time PCR. Results Totally 6 SNPs were found in PTP-1B gene. Three SNPs (I5/37 C→A,I6/82 A→G, I7/301 C→T) were in the intron regions and the other 3 (E8/45 C→T, E9/35 G→A, E10/372 G→A)in the exon regions. Among them, E9/35 G→A was a newly found mutation site. The A allele frequency of I5/37 C→A, T allele frequency of I7/301 C→T and G allele frequency of I6/82 A→G in type 2 diabetes were significantly higher than those in the normal spouse group (P

Objective Visual electrophysiology and optical correlation tomography angiography(OCTA)were used to investigate differences in preoperative retinal function in patients with type 2 diabetic cataract(DC)without obvious retinopathy(NDR)and to determine the clinical application of whole-process blood glucose man-agement(WBGM)for improving postoperative vision in DC patients.Methods This study investigated the preop-erative and postoperative visual electrophysiology(N75,P100,photopic FERG,and scotopic FERG),peripapil-lary retinal nerve fiber layer(pRNFL)and peripapillary capillary vessel density(ppVD)data,as well as trends in these data changes during blood glucose management intervention.Results As the course of T2DM progressed,FBG and HbA1c increased,the N75 and P100 lategraduancy periods of patients gradually lengthened,and the photopic FERG,scotopic FERG,pRNFL,and ppVD values decreased at each postoperative time point.At the same time,the best corrected visual acuity(BCVA)of patients after surgery gradually decreased(P<0.05).Compared with that at 1 week after surgery,the BCVA of Group A(without whole-process blood glucose manage-ment)gradually increased at 1 month and 3 months after surgery but showed a downward trend at 1 year after sur-gery.The BCVA of Group B(with whole-process blood glucose management)gradually stabilized at 1 month after surgery,and at all time points after surgery,the BCVA of Group B was better than that of Group A.The results showed that N75 and P100 in Group A were greater than those in Group B,while the photopic and scotopic FERG,pRNFL,and ppVD(%)in Group A were lower than those in Group B.In addition,N75 and P100 in Group A showed a gradual prolongation trend at various time points after surgery,while photopic FERG,scotopic FERG,pRNFL,and ppVD(%)showed a gradually decreasing trend.However,the above data in Group B gradu-ally stabilized at 3 months after DC surgery,approaching the preoperative level of the group(P<0.05).In the state of whole blood glucose management,although N75 and P100 both reached their longest durations at 1 week af-ter surgery,N75,P100,photopic FERG,scotopic FERG,and pRNFL showed a gradually decreasing trend at 1 month and 3 months after surgery,while ppVD(%)gradually increased(P<0.05).At various time points from 3 months to 1 year after surgery,the overall trend of the above indicators remained stable and close to the preoperative values(P>0.05).Conclusion According to the results of the quantitative analysis of visual electrophysiology and OCTA,in DC patients without obvious retinopathy and with the worsening of diabetes,retinal function decreased,but whole-process blood glucose management effectively restored retinal function and improved visual quality after surgery.

Objective To explore the impact of artificial intelligence(AI)-assisted computing systems on the success rate of surgery,stereoscopic vision,and quality of life in patients with intermittent exotropia.Methods A total of 108 children(216 eyes)with intermittent exotropia who visited Ziyang Hospital of West China Hospital,Sichuan University from March 2021 to April 2023 were collected and randomly divided into Group A and Group B,with 54 children(108 eyes)in each group.Group A used the traditional calculation method,while Group B used the AI-assisted calculation method to determine the surgical volume of strabismus in children by the angles of strabismus at 6m and 33 cm.The success rate of surgery,postoperative angle of strabismus,stereoscopic visual function,horizontal and vertical perceptual eye positions,and quality of life[Child Intermittent Exotropia Questionnaire(CIXTQ)score]were compared between the two groups at 1 day,1 month,3 months and 6 months after surgery.Results At 1 day,1 month,3 months and 6 months after surgery,the success rate of surgery in Group B was significantly higher than that in Group A(all P＜0.05).Compared with the val-ues at 1 day after surgery,the angles of strabismus at 6 m and 33 cm in the two groups were significantly reduced at 1 month,3 months and 6 months after surgery(all P＜0.05);Group B had significantly lower angles of strabismus at 6 m and 33 cm than Group A at 1 day,1 month,3 months and 6 months after surgery(all P＜0.05).At 1 month,3 months and 6 months after surgery,the central and far stereoscopic visions of children in the two groups gradually increased,with the increase rate in Group B being significantly higher than that in Group A(Finter-group=76.59,P＜0.05);the proportion of children without stereoscopic vision in both groups gradually decreased,with a decrease rate in Group B being significantly higher than that in Group A(Finter-group=137.74,P＜0.05).At 1 month,3 months and 6 months after surgery,the horizon-tal and vertical perceptual eye positions in Group B showed a significant descend range compared with those in Group A(all P＜0.05).At 1 day,1 month,3 months and 6 months after surgery,the exotropia displacement of children in both groups gradually increased,and the displacement of children in Group B was significantly smaller than that in Group A at 1 month,3 months and 6 months postoperatively(all P＜0.05).At 1 month,3 months and 6 months after surgery,the CIX-TQ scores of children in the two groups increased gradually,with CIXTQ scores in Group B being significantly higher than those of Group A(all P＜0.05).Conclusion AI-assisted computing systems can effectively improve the success rate of intermittent exotropia surgery,enhance the establishment of stereoscopic visual function,improve visual quality,and sig-nificantly improve the quality of life of children.
