To summarize the nursing experience of a patient with dilated cardiomyopathy experiencing recurrent superior mesenteric artery embolism and gastrointestinal hemorrhage post-enterectomy.Nursing key points:the development of a hemorrhage-embolism dual-risk assessment program and prevention and control interventions;the implementation of rapid-response emergency care for hemorrhagic shock combined with septic shock;active anti-infective care;the implementation of sudden cardiac death and ventricular arrhythmia early warning care;the establishment of a collaborative community follow-up management mechanism.The patient was discharged successfully after 44 d of hospitalization.During the 12-week follow-up,LVEF was 41％,and the patient could take care of himself in daily life.

Objective To analyze the levels and functions of CD4+T cell subsets in mouse spleen and lung tissues after Streptococcus pneumoniae(S.P.)infection,and to explore the immune regulatory mechanisms S.P.infection.Methods Flow cytometry was used to detect the proportions of CD4+T cell subsets(Th1,Th2,Th17,and Treg cells)in mouse spleen tissues from control group(n=4),S.P.infection at 12 h(n=4),and 24 h(n=4).H&E staining was used to examine lung tissue pathological characteristics.Differential gene sets and functional changes in lung tissues were analyzed after S.P.infection for 2 and 5 days,and immune cell abundance was predicted.Results Significant inflammatory pathological features were observed in the lung tissues of mice after S.P.infection.The proportions of Th1 and Treg cells in the spleen tissues gradually increased after S.P.infection,with Th1 and Treg cell proportions significantly higher than the control group at 24 h post-infection(P<0.05).At 5 d post-infection,only Treg cell proportion was significantly higher than the control group(P<0.05).Functional analysis revealed abnormal activation of IL6,IL10,and IL4/IL13 signaling pathways 2 days after infection,and abnormal enrichment of IL-2 and IL-6/TGF-β pathways 5 days after infection.Conclusion Treg and Th1 cells are key immune regulatory cells in mice following S.P.infection.Modulating Treg cell function mediated by IL-10 and Th1 cell function mediated by IL-2 can improve immune responses after S.P.infection.

The endoplasmic reticulum quality control(ERQC)system is a core mechanism for maintaining cellular homeostasis,which primarily mediates the degradation of misfolded proteins in the endoplasmic reticulum(ER)through the ER-associated degradation(ERAD)and ER autophagy(ER-phagy)pathways.Tripartite motif 13(TRIM13)is a protein located on the ER membrane,which plays a critical role in ERAD via its E3 ubiquitin ligase activity.TRIM13 also acts as a non-classical ER-phagy receptor to mediate the occurrence of ER-phagy.TRIM13 has recently received extensive attention in the field of ERQC.Here we review the structure and function of TRIM 13 and the mechanisms by which it contributes to ERQC,and summarize its abnormal expression and regulatory role in diseases,with the aim of providing new strategies for the treatment of related diseases.

Objective:To investigate the short-term therapeutic effect and long-term survival of multiple myeloma patients with extramedullary disease (EMD) in the new drug era.Methods:The data of 74 patients with multiple myeloma diagnosed and treated in Anhui Wanbei Coal and Electricity Group General Hospital from January 2015 to January 2020 were retrospectively analyzed, including 17 patients with soft tissue infiltration (EM-S), 9 patients with bone infiltration (EM-B), and 48 patients without EMD (No-EMD). The short-term efficacy, the 4-year progression-free survival (PFS) rate and overall survival (OS) rate, and their influencing factors in three groups of patients after receiving bortezomib regimen were analyzed.Results:After 3-4 courses of early induction therapy of bortezomib regimen, the overall response rate of patients in the EM-S group was lower than that in the No-EMD group and the EM-B group [58.8% (10/17) vs. 85.4% (41/48), 100.0% (9/9)], and the differences were statistically significant ( χ2 = 13.7, P = 0.036; χ2 = 26.5, P = 0.003), while the difference between No-EMD group and EM-B group was not statistically significant ( χ2 = 12.7, P = 0.211). Survival analysis showed that the 4-year PFS rate of No-EMD group was higher than that of the EM-S group and EM-B group (41.0% vs. 7.6%, 0), and the differences were statistically significant ( χ2 = 10.835, P < 0.01; χ2 = 8.276, P = 0.004). Meanwhile, the 4-year OS rate of EM-S group was lower than that of the No-EMD group and EM-B group (16.5% vs. 54.3%, 59.3%), and the differences were statistically significant ( χ2 = 9.146, P = 0.002; χ2 = 4.066, P = 0.044). Conclusion:The early treatment effect of bortezomib regimen, PFS and OS in multiple myeloma patients with EM-S are poor, while the EM-B has no effect on OS.

Objective To investigate the standard rate and common types of mistakes in ventricular intracranial pressure monitoring in neurosurgery intensive care unit ( NICU ) . Methods A total of 45 nurses were enrolled by convenience sampling method and investigated with assessment criteria developed by Department of Neurosurgery. Results There were 75. 6% nurses conformed to the operation standard, while 24. 4% nurses didn′t. The common types of mistakes were ventricular drainage unclosed before measuring pressure (37. 5%), measuring pressure without zero correction (25. 0%), incorrect zero position (16. 7%), measuring pressure immediately after nursing operations (8. 3%), measuring pressure without patients′head at median position (8. 3%), and tubes obstruction (4. 2%), etc. The different ages, professional (technical) titles and working years of nurses in ICU were the influencing factors of standardized ventricular intracranial pressure monitoring. Conclusions Nurses have some non-standard operation and multiple practice during ventricular intracranial pressure monitoring. More attentions should be paid to provide standardized ventricular intracranial pressure monitoring training for nurses who are young, low occupational title and short of working experience in ICU.

Objective To study the application of advance simulation check in perimetry. Methods A total of 80 perimetry patients were selected as control group ( traditional method) from October 2013 to December 2013 in Ophthalmology Department. They were divided into middle aged group (aged 30-49) and old age group (aged 50-70) on average because big range of ages. A total of 80 perimetry patients with a visual field analyzer were selected as observation group (advance simulation check method) from January 2014 to March 2014. They were also divided into two groups as the same method. We recorded and compared the examination time and the pass rate of perimetry of two groups. Results The mean time of examination in middle aged patients was (5.35 ±0.45)min in the control group and (5. 27 ± 0. 38) min in the observation group. There was no significant difference in the time of visual field examination between two groups (t=0. 848, P>0. 05). There was a significant difference between two groups in first-pass rate of middle aged patients (65. 00% in the control group vs 90. 00% in the observation group) (χ2 =7. 17, P<0. 01). The mean examination time and first-pass rate of old aged patients were (6.17 ±0.92)min, 62.50% in control group and (5.68 ±0.52)min, 82.50%in observation group. Comparing old aged patients of two groups, the differences were statistically significant (t/χ2 =2. 93,6. 67;P<0. 05). Conclusions Advance simulation examination can improve first-pass rate of middle aged patients and shorten the examination time of older patients. It can improve the examination′quality, save the time, relieve the pain of patients caused by examination and improve work efficiency.

Objective To explore the prognostic risk factors of low level malignant obstructive jaundice treated with transhapetic biliary drainage.Methods The clinical data of 142 patients with low level malignant obstructive jaundice received percutaneous transhapetic biliary drainage management from January 2010 to June 2013 were retrospectively analyzed.The study parameters included gender,age,tumor type,preoperative obstructive time,preoperative infection,drainage method,Child-Pugh grade,serum total bilirubin (TBIL),albumin (ALB),serum creatinine (SCr),the postoperative declining degree of bilirubin and postoperative antineoplastic therapy.The prognostic risk factors were evaluated.Results Single variable analysis showed that preoperative infection (P =0.006),Child-Pugh grade (P =0.004),SCr (P =0.043),the postoperative declining degree of TBIL (P =0.001) and postoperative antineoplastic therapy (P =0.015) were the related factors for survival time.The further Logistic regression analysis showed that preoperative infection (OR =3.729,95％ CI 1.332-6.363,P =0.040),Child-Pugh grade ≥ 10 scores (OR =0.513,95％ CI 0.375-1.276,P =0.018) and postoperative antineoplastic therapy (OR =0.668,95％ CI 0.210-2.026,P =0.038) were the related factors for survival time.Conclusion In treating of low level malignant obstructive jaundice with transhapetic biliary drainage,the preoperative infection,Child-Pugh grade and postoperative antineoplastic therapy may be the important related factors that affect the patient's survival time,to evaluate the prognosis of these patients has important reference meaning.
