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 study the changes in erythrocyte osmotic fragility(EOF)in patients with hypercythemia,pol-ycythemia and anemia under a high altitude environment.Methods A total of 174 outpatients,inpatients and people un-dergoing physical examination in Tibet Autonomous Region People′s Hospital in October 2020 were enrolled and divided into four groups according to hemoglobin levels:the polycythemia group(n=42),the physiologic increase group(n=48),the a-nemia group(n=29)and the healthy control group(n=55).They were compared with 67 anemia patients and 67 healthy people in the laboratory of Peking Union Medical College Hospital in the same period as the plain control group.The classic EOF test method was used to compare the results of each group′s EOF.The concentrations of NaCl solution for starting he-molysis(STH)and NaCl solution for complete hemolysis(CTH)were included,and the data were statistically analyzed by SPSS software.Results There was a significant difference in CTH between Zang and Han healthy people(P＜0.05).STH in high altitude polycythemia group(0.52)was higher than that in high altitude healthy control group(0.48)(P＜0.001).Compared with plain,the median CTH of plateau anemia group(0.36)and plateau health control group(0.36)was signifi-cantly higher than that of plain anemia group(0.28)and plain control group(0.28)(P＜0.001).Multivariate logistic regres-sion analysis showed that plateau region,female polycythemia and anemia were risk factors for STH elevation.Conclusion This study finds that the EOF increases in the plateau population and patients with polycythemia,which provides reference for studying red blood cell disorders and blood transfusion strategy in the plateau region.

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 evaluate the effects of the cassette 14C-urea breath test kit, scintillation sampling bottle (solid-state scintillation method) and liquid scintillation 14C-urea breath test kit in the diagnosis of Helicobacter pylori ( H. pylori) infection. Methods:From January 7 to October 28, 2020, 239 patients were enrolled who visited Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine, the Second Affiliated Hospital of Zhejiang University School of Medicine and the First Affiliated Hospital of Nanchang University. All subjects first received 14C-urea breath test.Within >1 to <7 days after gas collection, mucosal tissues were taken under gastroscopy for gold standard test, including biopsy and rapid urease test (RUT). If both biopsy and RUT indicated H. pylori positive, the result of gold standard test was H. pylori positive, and if both were negative, the result of gold standard test was H. pylori negative. If the results of biopsy and RUT were inconsistent, they were not included in the subsequent analysis. Based on the results of gold standard test, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of the cassette 14C-urea breath test kit, scintillation sampling bottle, and liquid scintillation 14C-urea breath test kit in the diagnosis of H. pylori infection were analyzed. The safety of the test was evaluated by whether there were any adverse events during the test. Descriptive methods were used for statistical analysis. Results:Among the 239 subjects, 12 cases did not complete the test, 227 subjects finally completed the test. The test completion rate was 95.0% (227/239). No.008 patient was only included in the analysis of cassette 14C-urea breath test kit and scintillation sampling bottle because of lacking the result of liquid scintillation breath test. The results of gold standard test showed that among 227 patients, 87 cases were H. pylori positive, 118 cases were H. pylori negative. The results of biopsy and RUT were inconsistent in 22 cases, so they were not included in the subsequent analysis. Excluding No.008 patient, the results of gold standard test showed that 86 cases were H. pylori positive and 118 cases were negative. Based on the results of gold standard test, the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of cassette 14C-urea breath test kit, scintillation sampling bottle, and the liquid scintillation 14C-urea breath test kit in the diagnosis of H. pylori infection were 91.9%, 100.0%, 96.6%, 100.0% and 94.4%, respectively; 95.4%, 97.5%, 96.6%, 96.5% and 96.6%, respectively; and 96.5%, 99.2%, 98.0%, 98.8% and 97.5%, respectively. Only one adverse event (right upper abdominal pain after eating) occurred. Combined with the patients condition, the adverse event was determined as the onset of chronic cholecystitis and it might not be related to the test medication. Conclusions:Cassette 14C-urea breath test kit, scintillation sampling bottle, and liquid scintillation 14C-urea breath test kit have reliable performance, good safety, and high sensitivity, specificity and accuracy in the diagnosis of H. pylori infection, which are worthy of clinical application.

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.

Objective To explore the effect of the improved abdominal rotation card method in insulin injection. Methods A total of 100 hospitalized diabetes patients were randomly divided into control group (n=50) and observational group (n=50) according to the random number method. In the control group, insulin was injected to the subcutaneous tissue of abdomen with traditional method annular rotating method. Insulin was injected using improved abdominal rotation card method in the observational group. Compare accuracy and mastery rate of injection site rotation between the two groups. Compare fasting blood glucose (FBG), postprandial 2H blood glucose (PBG), HbA1c, the incidence of hypoglycemia and endermic induration between the two groups after three months. Results The nurses in the observation group had higher accuracy rate of the injection site rotation compared to the control group [98.6%(690/700) vs. 38.6%(270/700),χ2=584.66, P<0.01]. Mastery rate of the injection site rotation for the patients in the observation group were significantly higher than the control group [70.0% (35/50) vs. 20.0% (10/50), χ2=25.74, P < 0.01]. The incidence of endermic induration were significantly lower in observation group compared to the control group [2.0% (1/50) vs.16.0% (8/50), χ2=5.98, P < 0.01]. The incidence of hypoglycemia were significantly lower in observation group compared to the control group [4.0%(2/50) vs. 16.0%(8/50),χ2=4.00, P<0.01]. Conclusions The new abdominal rotation method in insulin injection can be a safe and effective therapy in patients with type 2 diabetes.

OBJECTIVETo investigate the etiology of severe hand-foot-mouth disease (HFMD) in children in Henan province.

METHODSA total of 244 HFMD cases admitted to a hospital in Zhengzhou from April to June of 2014 were recruited for research sampling, Real-time RT-PCR, virus isolation, VP1 sequencing and alignment methods were used to test the enterovirus-related etiology. SPSS 17.0 was used in performing statistical analysis.

RESULTSThere were 109 severe and 135 mild cases among all the 244 HFMD cases. The number of enterovirus positive stool samples was 229, with positive rate as 93.85%. EV71, Cox A16 and Cox A10 made up 83.84%, 5.68% and 8.30% of the enterovirus etiologicy, strains, respectively. EV71 infection caused 8 HFMD cases with heart-lung failure and 2 death, Cox A10 infection led to 1 HFMD case with heart-lung failure and death. There were statistically differences seen regarding the enterovirus infection rates between severe and the mild HFMD cases (χ(2)=5.312,P=0.021). Statistically significant difference was seen in the constituent ratio of EV71, Cox A16 and the others by Fisher' s exact test (P=0.048). There was statistically significant difference seen between the cardiorespiratory failure rate and the fatality rate by EV71 and Cox A10 infection (χ(2)=0.051,P=0.821; χ(2)=2.198,P=0.138). Cox A10 strains idenfied in Henan in 2014 belonged to genotype 6. The rates on homology of nucleotide and amino acid among the Cox A10 strains in Henan in 2014 were 94.3%-99.7% and 96.3%-100.0% respectively.

CONCLUSIONSEV71 still remained the most common pathogen that causing severe HFMD in children, with the increasing Cox A10 percentage in the pathogens spectrum of HFMD infection. Cox A10 strains in Henan in 2014 belonged to genotype 6. Genotype 6 Cox A10 had appeared and widely distributed in Henan for long time, but not yet variated or reconstructed. Cox A10 infection could lead to cardio-respiratory failure thus called for the monitoring program on non-EV71 and non-Cox A16 enterovirus, especially Cox A10 to be strenthened.
