Objective To investigate the impact of nursing interventions based on Kales conceptual model on agitated behaviours of dementia patients.Methods A total of 80 dementia patients were randomly divided into two groups using a random number table.Patients in the control group(n=40)received routine care,while those in the observation group(n=40)received the nursing interventions based on Kales concept model on top of the routine care.The agitated behaviours and quality of life of the two groups were compared before,2 weeks and 4 weeks after the intervention.Results The repeated measures ANOVA showed statistically significant differences in three time points in terms of the time effect,inter-group effect and interactive effects on the scores of agitations and quality of life(all P<0.05).After the intervention,the score of agitations in the observation group was significantly lower than that of the control group(P<0.05),and the score of quality of life in the observation group was significantly higher than that in the control group(P<0.05).Conclusion The nursing interventions based on Kales conceptual model is effective in reducing agitations of dementia patients and improving the quality of life.

OBJECTIVE To analyze the use status and development trend of proton pump inhibitors(PPIs) in 33 hospitals in Wuhan, Hubei Province after the implementation of the national centralized drug procurement(NCDP) policy, and to provide reference for promoting the subsequent rational use of NCDP drugs and improving related policies. METHODS To make statistics and analysis of purchasing amount of PPIs, defined daily dose system(DDDs), defined daily dose consumption(DDDc) and utilization rate of 33 hospitals in Wuhan in 2019 and 2022. RESULTS After the implementation of the NCDP policy, the total purchasing amount of PPIs decreased by 53.6%, DDDs decreased by 15.4%, DDDc decreased by 45.2%, and the utilization rate of PPIs injectable dosage forms decreased by 12.6%. After NCDP, the highest growth rate of oral dosage forms was omeprazole(5.7%), followed by rabeprazole(5.0%), while injectable dosage forms showed a significant difference in utilization rate, with a significant decline in NCDP varieties and a significant increase in non-NCDP varieties. The overall NCDP utilization rate of PPIs in Wuhan was 64.9%, with little difference among hospitals of different grades. CONCLUSION The NCDP policy achieves the purpose of reducing the drug cost of patients and improving the accessibility of drugs, and is more optimized in the selection of dosage forms, which is in line with the policy expectations overall; but the quantity and price of PPIs in Wuhan decreased after NCDP, and highlighted a certain tendency in the selection of varieties. In the future, we still need to optimize measures to guide clinical priority in the selection of NCDP drugs, to ensure and improve the implementation of NCDP policy.

Objective:To evaluate the efficacy and safety of rituximab(RTX) as remission-mainten-ance therapy in antineutrophil cytoplasmic antibody(ANCA) associated vasculitis(AAV).Methods:Patients with AAV, including granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA), treated with rituximab (RTX) in Peking Union Medical College Hospital during September 2005 to June 2021 were included into this study. Clinical data, relapse rate, time of first relapse and adverse events were collected and analyzed. The cumulative relapse rate was calculated by Kaplan-Meier, t test, and Man-Whithey U test and chi-square were used to compare differences between two groups. Results:① Thirty-nine AAV patients were enrolled, including 36 GPA and 3 MPA. During the 20(3, 104) months follow-up, 59.0%(23/39) patients had suffered relapses. The time for first relapse was 11(3, 42) months after remission. ② There were no difference in the relapse rate [60.0%(18/30) vs 55.6%(5/9), χ2=0.06, P=1.000), the time of first relapse [15(3, 42) vs 10(9, 30), Z=0.45, P=0.678], CD19 + B [23.5 (5, 148) cell/μl vs 3(2, 15) cell/μl, Z=0.57, P=0.605] and serum IgG [7.09(5.13, 13.90) g/L vs 9.72(5.32, 12.0) g/L, Z=0.36, P=0.770] between standard dose and low-dose groups. The rate of major relapse-free was significantly less in patients treated with standard dose than patients with reduced dose of RTX {87.1%[95% CI(73.4%, 100.8R%)] vs 64.3%[95% CI(23.1%, 105.4%)], χ2=7.59, P=0.006}. ③ There were no difference in relapse rate [50.0%(3/6) vs 60.6%(20/33), χ2=0.24, P=0.674], time of first relapse [23(6, 25) vs 11(3, 42), Z=0.05, P=0.982], CD19 + B[35(15, 50) cell/μl vs 10(0, 148) cell/μl, Z=0.95, P=0.382] and serum IgG[6.70(5.91, 7.49) g/L vs 7.69(3.78, 13.90) g/L, Z=0.48, P=0.700] between the fixed interval dosage and the on-demand dosage groups. There was no difference in the rate of major relapse-free between the two groups (100% vs 77.8%, χ2=1.79, P=0.181). ④ The incidence of infusion reaction was 5.1%(2/39) and infection was 20.5%(8/39). Serum IgG level was 4.37(3.78, 13.4) g/L at infection. There was no difference in safety between the standard and low-dose groups or between fixed interval and on-demand dosage groups ( P>0.05). Conclusion:There is no significant difference in relapse rate bet-ween the standard RTX dose and low-dose RTX induction therapy group, but the major relapse rate is sign-ificantly reduced in the standard dose RTX therapy. The relapse rate of fixed intervals dosage group is similar to that of on-demand dosage group. The safety profile of the standard dose and low-dose induction therapy groups or fixed intervals and on-demand dosage groups is similiar.

Objective:To explore the clinical features and survival of newly diagnosed follicular lymphoma (FL) patients with diffuse large B-cell lymphoma (DLBCL) component.Methods:1845 newly diagnosed FL patients aged ≥ 18 years with grades 1-3a in 11 medical centers in China from 2000 to 2020 were included, and patients with DLBCL component were screened. The clinical data and survival data of the patients were retrospectively analyzed, and the prognostic factors were screened by univariate and multivariate analysis.Results:146 patients (7.9% ) with newly diagnosed FL had DLBCL component. The median age was 56 (25-83) years, 79 males (54.1% ) . The pathology of 127 patients showed the proportion of DLBCL component. Patients were divided into two groups according to whether the proportion of DLBCL component was ≥ 50% . The study found that patients with DLBCL component ≥ 50% had higher grade 3 ratio (94.3% vs 91.9% , P=0.010) , Ki-67 index ≥ 70% ratio (58.5% vs 32.9% , P=0.013) and PET-CT SUVmax ≥ 13 ratio (72.4% vs 46.3% , P=0.030) than patients with DLBCL component<50% . All patients received CHOP or CHOP like ± rituximab chemotherapy. The overall response rate (ORR) was 88.2% , and the complete response (CR) rate was 76.4% . In the groups with different proportions of DLBCL component, there was no significant difference in the remission rate after induction treatment and the incidence of disease progression within 2 years after initiation of treatment (POD24) ( P<0.05) . The overall estimated 5-year progression free survival (PFS) rate was 58.9% , and the 5-year overall survival (OS) rate was 90.4% . The 5-year OS rate of POD24 patients was lower than that of non POD24 patients (70.3% vs 98.5% , P<0.001) . Compared with non maintenance treatment of rituximab, maintenance treatment of rituximab could not benefit the 5-year PFS rate (57.7% vs 58.8% , P=0.543) , and the 5-year OS rate had a benefit trend, but the difference was not statistically significant (100% vs 87.8% , P=0.082) . Multivariate analysis showed that failure to reach CR after induction treatment was an independent risk factor for PFS ( P=0.006) , while LDH higher than normal was an independent risk factor for OS ( P=0.031) . Conclusion:FL patients with DLBCL component ≥50% have more invasive clinical and pathological features. CHOP/CHOP like ± rituximab regimen can improve the clinical efficacy of patients. Rituximab maintenance therapy can not benefit the PFS and OS of patients. Failure to reach CR after induction therapy was the independent unfavorable factor for PFS.

Abstract To study the antiviral effect ofZedoary TurmericOil Injection on novel coronavirus, SARS-CoV-2 viroid cell lines were preparedin vitroand treated with different concentrations of Zedoary Oil. The cell number and relative fluorescence value(RLU) were observed and measured, and the 50% effective inhibitory concentration(IC 50) was calculated. Four patients with Coronavirus Disease 2019 were clinically included, including 2 in the control group and 2 in the experimental group. The control group received conventional treatment, and the experimental group receivedZedoary TurmericOil Injection in addition to conventional treatment. The nucleic acid conversion rate, conversion time, pulmonary imaging changes, fever reduction time, clinical improvement time and adverse events of the patients were observed.In vitroexperiment, the relative fluorescence value decreased with increasing concentration ofZedoary TurmericOil, which was significantly different from that of the control group(P<0.05). The IC50 was 0.26 μg/ml.In vivostudy, the novel coronavirus nucleic acid in stool of case 1 in the test group turned negative in 3 days, the cough symptom of case 2 was significantly relieved, and there was obvious absorption in pulmonary imaging. The negative conversion time of novel coronavirus nucleic acid in the control group was 5 and 7 days respectively. No adverse events occurred in the experimental group.Zedoary TurmericOil had strong inhibitory effect on SARS-COV-2 virusin vitrowhich was dose-dependent.In vivotreatment of COVID-19,Zedoary TurmericOil Injection combined with conventional treatment can improve the cough caused by SARS-COV-2 infection, promote SARS-COV-2 to turn negative, promote absorption of lung lesions, and reduce lung injury, with no obvious adverse events.

Objective:To study the clinicopathologic features, and the diagnosis and differential diagnosis of mycobacterial spindle cell pseudotumor in children.Methods:The clinical data, histopathological features, immunophenotype and special staining of 2 mycobacterial spindle cell pseudotumors were analyzed. The related literatures were reviewed.Results:The age of the two boys was 11 months and 22 months respectively, but their clinical symptoms became apparent at the age of about 4 months. The lesions involved lymph nodes and skin. The first patient also had fever for more than 4 months. Both patients received anti-inflammatory treatment in the outside hospital, but had no obvious improvements of the symptoms. A tumor resection was performed at the outside hospital. Histologically, mycobacterial spindle cell pseudotumor consisted of bland spindle cells, which formed fascicles, without any obvious atypia and mitoses. The cell nuclei were vesicular, with small nucleoli and abundant cytoplasm in some of the cases. The spindle cells expressed histiocyte-associated markers, such as CD68. The Ki-67 proliferation index was low. The mycobacteria were usually readily highlighted by acid-fast staining, which located in the cytoplasm of proliferative spindle cells. In the first case, there was obstructive jaundice because of the progressive enlargement of live portal lymph nodes and systemic disseminated lesions. The second patient had disease recurrence after only operation, and gradually developed other skin nodules and superficial lymph node enlargement. The high-throughput molecular analysis of the skin biopsy confirmed the diagnosis of mycobacterium tuberculosis. After 11 days of anti-tuberculosis treatment, the patient′s condition improved significantly.Conclusions:Mycobacterial spindle cell pseudotumor in children is a very rare benign lesion. It is characterized by spindle-histiocyte proliferation caused by mycobacterium infection. An acid-fast stain appears necessary for confirming the diagnosis.

Objective To explore the effect of nursing project management on reducing the incidence of perioperative pressure injury during laparoscopic pancreaticoduodenectomy. Methods The pressure ulcers conditions of 41 cases undergoing laparoscopic resection of pancreatic duodenal from December 2014 to July 2015 were investigated to find out the causes of the incidence of pressure ulcers, and we made pertinent measures for continuous quality improvement. From August 2015 to March 2016, 45 patients underwent laparoscopic pancreatoduodenectomy received nursing project management nursing care. Two groups of patients in terms of the incidence of pressure ulcers, pressure ulcer risk assessment accuracy and implementation rate of patient skin specification handover were compared. Results The incidences of laparoscopic resection of pancreatic duodenal ulcer decreased from 24.39% before the improvement of the project to 2.22%, the accuracy of nurse on the laparoscopic resection of pancreatic duodenal ulcer risk assessment increased from 75.60% to 95.55%, the implementation rate of patient skin specification handover increased from 82.93% to 97.78%, the differences were statistically significant (P<0.05). Conclusions The implementation of nursing program can reduce the incidence of pressure injury and improve the quality of nursing in perioperative period of laparoscopic pancreaticoduodenectomy.

Unplanned extubation (UEX) is defined as premature removal of the indwelling catheter tube by a patient (deliberate unplanned extubations) or by staff during nursing and medical care (accidental extubations). UEX, either deliberate or accidental, can cause severe damage of patients, with the increasing of hospital costs and medical disputes. Identifying high-risk patients is the key point of reducing UEX. This review conclude risk assessment tools reported for UEX.

With the development of society and the increasing of medical treatment level,the number of hospitalized patients is also increasing,and the hospital falls has been paid increasing attention to in hospital administrators because of the hospital environmental factors.According to the current situation,the incidence of falls in hospitalized patients with environmental risk factors for falls and intervention strategies were reviewed, and the aim was to provide reference for scientific and effective prevention of falls in hospitalized patients.

Objective To explore the impact of IL10-592 (rs1800872) single nucleic acid polymorphism (SNP) on the prognosis of HLA matched unrelated hematopoietic stem cell transplantation (HSCT).Methods The polymorphism of IL10-592 in 104 recipient-donor pairs and 100 healthy volunteers was analyzed with sequence based typing (SBT).Results When the genotype of IL1 0-592 in donors and recipients matched,AA/AA genotype had higher incidence of Ⅲ-Ⅳ aGVHD than AC/AC or CC/CC genotype (47.1％,3.7％,0,P=0.002).When the genotype of IL10-592 in donors and recipients mismatched,recipients with AC genotype or donors with AA genotype,there was significant different incidence of Ⅲ-Ⅳ aGVHD among donors or recipients with different genotype (P=0.046,P=0.041).The recipients with AA genotype had higher incidence of Ⅲ-Ⅳ aGVHD than AC or CC genotype (27.8％ vs 10.2％,11.1％;P=0.072),and higher incidence of intestinal aGVHD (22.2％vs 5.1％,11.1％;P=0.040),lower incidence of 2-year overall survival (OS:48.2％ vs 75.1％,85.7％;P=0.002),lower incidence of 2 year disease free survival (DFS:48.5％ vs 66.3％,76.2％;P=0.045).Patients had higher incidence of Ⅲ-Ⅳ aGVHD with donors of AA genotype than with donors of AC or CC genotype (26.5％ vs 8.9％,0;P=0.024),and higher incidence of intestinal aGVHD (20.4％ vs 4.4％,0;P=0.026).In multivariate analysis,the genotype of IL10-592AA in recipients and donors had increased risk of Ⅲ-Ⅳ aGVHD (OR=3.3,P=0.049;OR=3.9,P=0.043).There were no statistical differences on the incidence of cGVHD and relapse.Conclusion In HLA-10/10 matched unrelated HSCT,the presence of IL10-592 AA genotype in recipients and/or donors is an adverse factor for Ⅲ-ⅣaGVHD,worse OS and 2-year DFS.
