Objective:To explore the effect of therapeutic communication on infusion safety, disease uncertainty, coping styles, anxiety and depression in patients with emergency infusion.Methods:A total of 126 patients treated with infusion patients in emergency department in Jiangsu Provincial People's Hospital, the First Affiliated Hospital of Nanjing Medical University from July 2019 to December 2019 were selected and divided into two groups by random digits table method with 63 cases in each group. Patients in the control group received routine nursing, and patients in the intervention group received therapeutic communication nursing intervention on this basis. The incidence of adverse events of infusion during the intervention of the two groups of patients was observed. The disease uncertainty, coping styles, anxiety and depression were evaluated by Mishel's Uncertainty in Illness Scale (MUIS), Medical Coping Mode Questionnaire (MCMQ), Self-rating Anxiety Scale (SAS) and Self-rating Depressive Scale (SDS) before and after intervention.Results:The final collection of 109 patients with complete questionnaire, the recovery rate was 86.51% (109/126), including 55 cases in the intervention group, 54 cases in the control group. The incidence of adverse events of infusion was 16.36%(9/55) in the intervention group and 29.63%(16/54) in the control group, and there was significant difference( χ2 value was 5.057, P<0.05). There was no significant difference in the score of MUIS, MCMQ, SAS, SDS before the intervention between the two groups ( P>0.05). After the intervention, the uncertainty, unpredictability, lack of information and complexity dimension of the intervention group patients' MUIS scores were respectively (17.76 ± 2.49), (12.03 ± 2.51), (11.82 ± 2.12), (11.74 ± 2.24), which were lower than those in the control group (24.72 ± 2.94), (16.31 ± 2.27), (16.13 ± 2.51), (15.39 ± 2.31), the differences were significant( t values were -13.346- -8.375, P<0.05). The confront score of the intervention group patients' MCMQ was (19.13 ± 2.62) higher than that in the control group(13.79 ± 1.96), the avoidance and yield scores were respectively (8.71 ± 1.34), (9.81 ± 1.17), which were lower than those in the control group (14.57 ± 1.93), (15.12 ± 1.86), the differences were significant( t values were 12.031, -18.441, -17.875, P<0.05). The scores of SAS and SDS in the intervention group were (29.43 ± 3.62), (27.67 ± 3.11) respectively, which were lower than those in the control group (37.44 ± 5.31), (40.12 ± 4.92), the differences were significant( t values were -9.216, -15.821, P<0.05). Conclusions:Therapeutic communication can reduce the risk of emergency infusion, reduce the uncertainty of patients to the disease, improve patients' countermeasures to the disease, relieve patients' anxiety and depression, and improve the nursing quality of emergency infusion patients.

Objective To understand the etiology of acute hepatitis B (AHB) in adults and investigate the mechanisms of hepatic injury and viral clearance in AHB. Methods One hundred and twenty adult AHB patients were enrolled. Epidemiological and clinical data were collected from the case history records or face-to-face inquiry, and serum samples were collected during hospitalization and follow-up. To observe dynamic patterns of AHB etiology, the markers of hepatitis B virus (HBV) were detected by enzyme-linked immunosorbent assay (ELISA); the level of HBV DNA and HBV genotype were determined by real-time polymerase chain reaction (PCR). Enumeration data were analyzed by non-parametric rank sum test. Comparison between groups was done by t test and that between rates of samples was done by Pearson χ2 test. Results Serum HBV DNA was positive in 48.33% of patients at the time of diagnosis with mean level of 9.84×04 copy/mL, and became undetectable after 12.5 days on average. The median levels of serum alanine aminotransferase (ALT) were 1600 U/L and 1490 U/L in HBV DNA positive and negative groups, respectively (z=-0. 678, P=0. 498). However, the mean levels of serum ALT were (2058±123) U/L and (1393±139) U/L in groups of HBV DNA<1×104 copy/mL and>1×104 copy/mL, respectively, which was significantly different (t=-2.17, P=0. 049). Genotype B accounted for 52.5%, genotype C 42.5 and genotype B and C mixed type 5.0% in 58 patients with HBV DNA positive. Eight patterns of serum HBV markers were presented at first visiting. HBsAg(+), HBeAg(+), anti-HBc(+), anti-HBc IgM(+) and HBsAg(+), anti-HBe(+), anti-HBc(+), anti-HBc IgM(+) were the most common patterns, which accounted for 38.3% and 30.0%, respectively. The dynamic patterns of serum HBV markers of 28 AFIB patients were prospectively followed up. The rate of serum FIBsAg loss was 100. 0% and the median time of negative-conversion was 3 weeks. The cumulative positive rate of anti-HBs was 85.7% after 52 weeks of follow-up. The rate of serum HBeAg loss was 100.0%. HBeAg was negative in 53.6% of patients at first visiting and the rest of patients achieved negative within 4 weeks after onset. The positive rate of anti-HBe was 82.1% during 52 weeks of follow-up. Total anti-HBc (including IgG and IgM) was keeping positive in all patients within 52 weeks, and the negative rate of anti-HBc IgM was 39. 3% after followed up for 52 weeks. Conclusions Rapid HBV clearance andserum HBV marker conversion are significantly different between AHB and chronic hepatitis B.

Objective To study Edg4 and Edg7 expression in placenta of women with hypertensive disorder complicating pregnancy,and to investigate the relation between the expression of lysophosphatidic acid(LPA)and hypertensive disorder complicating pregnancy.Methods Immunohistochemical SP method was used to measure the expressions of Edg4 and Edg7 in placenta of women with normal pregnancy,20 women with gestational hypertension,20 with mild preeclampsia,and with severe preeclampsia.Results (1)Location:immunohistoehemical staining for Edg4 and Edg7 protein were located at the membrane and endoehylema of cytotrophoblast as well as decidua cells.(2)The positive expression of Edg4 protein and Edg7 protein on membrane and endochylema of cytotrophoblast was 25% and 20%(normal women),60% and 40%(gestational hypertension),80% and 65%(mild preeclampsia),and 83.3% and 86.7%(severe preeclampsia).The expression of Edg4 and Edg7 protein in mild preeclampsia and severe preeclampsia was significantly correlated with the degree of differentiation(P0.05). (3)The positive expression of Edg4 protein and Edg7 protein on membrane and endochylema of decidua was 20% and 25%(normal pregnancy),55% and 50%(gestational hypertension),70% and 55%(mild preeclampsia),and 83.3% and 73.3%(severe preeclampsia)respectively.The expression of Edg4 and Edg7 protein in mild preeclampsia and severe preeclampsia showed a significant correlation with the degree of differentiation(P0.05).Conclusions The high expression of Edg4 and Edg7 protein in the placentas of patients with hypertensive disorder complicating pregnancy indicates that LPA combines with Edg4 and Edg7,inducing the occurrence of hypertensive disorder complicating pregnancy.

Objective To investigate the efficacy and safety of carotid angioplasty and stenting for carotid stenosis in high-risk symptomatic NASCET-ineligible patients. Methods Twenty patients with symptomatic carotid stenosis at high risk ineligible for NASCET were treated with carotid angioplasty and stenting,12 of them were men,and 8 wre women,the patients ranged in age from 62 to76 years (mean age,69 years). Eleven patients had transient ischemic attack and 9 had cerebral infarction. Digital subtraction angiography showed that the degree of carotid stenosis in all patients was ＞ 70% (NASCET criteria). Among them,9 patients had unilateral carotid artery severe stenosis (2 had restenosis after endarterectomy),6 had bilateral carotid artery severe stenosis,5 had unilateral carotid artery occlusion with contralateral severe sentoses (1 had undergone cervical radiotherapy for nasopharyngeal carcinoma). The embolic protection devices,predilation,and self-expandable stents were used in all patients. Results The success rate of the procedure was 100%. The residual stenosis rate was ＜ 30%. The different levels of a transient decline in heart rates and blood pressure occurred in all the patients during the procedure. One patient was complicated with microembolic embolism. No ischemic stroke occurred in the remaining patients in the periprocedure. The postoperative examination with carotid ultrasound showed that the stenoses were improved significantly. No ipsilateral ischemic stroke and coronary ischemic events were observed at 1 and 3 months follow-up after the procedures. Conclusions Carotid artery stenting is less invasive,and the perioperative complications are fewer,The treatment of symptomatic carotid stenosis with high surgical risks is safe and effective.
