Objective:To explore the application effect of Total Life Cycle Management(TLCM)in managing maintenance cost of ultrasound imaging equipment.Methods:Thirty ultrasound imaging equipment of the China-Japan Friendship Hospital from June 2021 to July 2023 were selected.From June 2021 to June 2022,a conventional maintenance mode was adopted to manage these equipment,and TLCM was implemented to manage them from July 2022 to July 2023.The qualified rate and failure frequency of the ultrasound imaging equipment,the satisfaction scores of medical staffs in using equipment,and the costs of operation and maintenance were compared between different management modes.Results:Under TLCM mode,the qualified rate was 93.33%,which was significantly higher than 73.33% under conventional maintenance mode,and the difference was significant(x2=4.320,P＜0.05). Under TLCM mode,the boot-up time of ultrasound imaging equipment was shorter than that under the conventional maintenance mode,and the difference was significant (t=7.146,P＜0.05). Under TLCM mode,the failure rate of long-term use of equipment was lower than that under conventional maintenance,and the difference was significant (x2=4.443,P＜0.05). The satisfaction scores of medical staffs for the performance,efficiency,and cleanliness of equipment under TLCM mode were higher than those under conventional maintenance mode,and the differences of them between two modes were significant (t=3.955,5.872,6.368,8.214,P＜0.05). Under TLCM mode,both maintenance costs and operational expenses were lower than those under conventional maintenance,and the differences of them between two modes were significant (t=41.353,16.743,P＜0.05). Conclusion:TLCM can effectively enhance operationally qualified rate of equipment,and reduce maintenance costs and failure rate of equipment in long-term use,and improves the satisfaction of medical staff.

Objective:To investigate the effects of the Epley and Semont procedures with varying lateral angles of the head on posterior semicircular canal benign paroxysmal positional vertigo （PC-BPPV）. Methods:A total of 115 patients with unilateral PC-BPPV were randomly divided into five groups: Epley group, Semont group, Semont+10° group, Semont+20° group, and Semont+30° group, with 23 patients in each group. Corresponding reduction treatments were performed. Results:The total effective rates for the Epley group, Semont group, Semont+10° group, Semont+20° group, and Semont+30° group were 95.7% （22/23）, 4.3% （1/23）, 30.4% （7/23）, 52.2% （12/23）, and 87.0% （20/23） respectively. The inefficiencies were 4.3% （1/23）, 95.7% （22/23）, 69.6% （16/23）, 47.8% （11/23）, and 13.0% （3/23）. Statistically significant differences were observed in the total effective rates among the five groups （χ²=54.11, P<0.01）. The total effective rates in the Semont group, Semont+10° group, and Semont+20° group were significantly different from that of the Epley group （P<0.01）, while no statistically significant difference was found between the Semont+30° group and the Epley group （P= 0.608>0.012 5）. Conclusion:Among the four Semont methods with different lateral lying angles, the total effective rate of reduction treatment increased with the elevation of the lateral lying angle on the affected side. The efficacy of the Semont+30° group in treating PC-BPPV was not significantly different from the Epley group's reduction effect, which was markedly superior to that of the other four Semont methods at different angles. Therefore, the Semont+30° reduction technique is recommended for the treatment of PC-BPPV.

Objective:To more accurately evaluate the function of the otolith organ and its conduction pathway of pilots by collecting the vestibular evoked myogenic potentials (VEMPs) corrected by electromyogram (EMG) in healthy military pilots and comparing bilateral amplitude, amplitude asymmetry ratio and other relevant parameters with and without EMG rectification.Methods:One hundred (200 ears) healthy male active duty military pilots were selected as study subjects, with an average age of (26.86±6.54) years old. The cervical vestibular-evoked myogenic potential (cVEMP) and ocular vestibular-evoked myogenic potential (oVEMP) induced by air conduction acoustic stimulation were performed to the subjects in sitting position. Sound was delivered through inserted earphones, with the stimulus being tone burst at 97 dB nHL. The P1 latency, N1 latency, P1-N1 wave interval latency, and the P1-N1 amplitude and amplitude asymmetry ratio of VEMPs were recorded before and after the correction of EMG and those were compared and analyzed.Results:The evoked rate of VEMPs was 100%. The latency of P1 and N1, P1-N1 interval of cVEMP in these pilots were (15.58±1.29), (26.12±1.91), and (10.54±1.49) ms. The latency of N1 and P1, P1-N1 interval of oVEMP in these pilots were (11.96±0.92), (16.92±1.06), and (4.96±0.75) ms. The difference of VEMPs amplitude before and after EMG correction was statistically significant ( Z=-17.30, -17.30, both P<0.001). The difference of amplitude asymmetry ratio of cVEMP before and after correction was statistically significant ( Z=-2.91, P=0.004), but the difference of amplitude asymmetry ratio of oVEMP before and after correction was not statistically significant ( P>0.05). Conclusions:This research sets up the normal range of VEMPs corrected by EMG in military pilots and provides a more accurate reference for medical selection of flying cadets and functional evaluation of the otolith organ and its conduction pathway.

Objective:To investigate the correlation factors of complete clinical response in idiopathic inflammatory myopathies(IIMs)patients receiving conventional treatment.Methods:Patients diagnosed with IIMs hospitalized in Peking University People's Hospital from January 2000 to June 2023 were in-cluded.The correlation factors of complete clinical response to conventional treatment were identified by analyzing the clinical characteristics,laboratory features,peripheral blood lymphocytes,immunological indicators,and therapeutic drugs.Results:Among the 635 patients included,518 patients finished the follow-up,with an average time of 36.8 months.The total complete clinical response rate of IIMs was 50.0％(259/518).The complete clinical response rate of dermatomyositis(DM),anti-synthetase syn-drome(ASS)and immune-mediated necrotizing myopathy(IMNM)were 53.5％,48.9％and 39.0％,respectively.Fever(P=0.002)and rapid progressive interstitial lung disease(RP-ILD)(P=0.014)were observed much more frequently in non-complete clinical response group than in complete clinical re-sponse group.The aspartate transaminase(AST),lactate dehydrogenase(LDH),D-dimer,erythrocyte sedimentation rate(ESR),C-reaction protein(CRP)and serum ferritin were significantly higher in non-complete clinical response group as compared with complete clinical response group.As for the treat-ment,the percentage of glucocorticoid received and intravenous immunoglobin(IVIG)were significantly higher in non-complete clinical response group than in complete clinical response group.Risk factor analysis showed that IMNM subtype(P=0.007),interstitial lung disease(ILD)(P=0.001),eleva-ted AST(P=0.012),elevated serum ferritin(P=0.016)and decreased count of CD4+T cells in peripheral blood(P=0.004)might be the risk factors for IIMs non-complete clinical response.Conclu-sion:The total complete clinical response rate of IIMs is low,especially for IMNM subtype.More effec-tive intervention should be administered to patients with ILD,elevated AST,elevated serum ferritin or decreased count of CD4+T cells at disease onset.

Brucellosis is a zoonotic infectious disease caused by Brucella infection. So far, animal to animal Brucellosis has not been eradicated, and there is a lack of safe and effective human vaccine. Therefore, "early, combined, sufficient, and full course" drug treatment remains an important strategy in the management of human Brucellosis. The goal of treating brucellosis is to alleviate and shorten the symptom period, reduce complications, relapses, and chronicity. At present, although antibiotic treatment is effective for most patients, there are still some patients who experience treatment failure or later recurrence, so the treatment strategy for brucellosis urgently needs to be optimized. This article elaborates on the treatment principles, clinical treatment status, and future development trends of brucellosis, in order to provide references for optimizing drug treatment methods for brucellosis.

Objective:To understand the impact of diet on glycemic control in community-managed patients with type 2 diabetes mellitus (T2DM) and provide evidence for implementing prevention strategies and measures for diabetes patients.Methods:Eight communities were randomly selected from Changshu and Wuhan in 2015, and T2DM patients managed in the community were selected to conduct questionnaire surveys, physical measurements, and blood glucose testing. Factor analysis was used to obtain dietary patterns. A binary logistic regression model was used to analyze the factors affecting glycemic control.Results:Finally, 1 818 T2DM patients were included, and the control rate of FPG was 57.59% (95% CI: 55.30%-59.86%), and the control rate of 2 h postprandial blood glucose (2 h PBG) was 24.90% (95% CI: 22.93%- 26.91%). Five dietary patterns were obtained by factor analysis: animal food pattern, fruit-aquatic products-potato patterns, vegetable-grain pattern, egg-milk-bean pattern, and oil-salt patterns. No-conditional multivariate logistic regression analysis showed that after adjusting for confounding factors, the reduced probability of FPG control was related to animal food pattern ( OR=0.71, 95% CI: 0.52-0.98) and fruit-aquatic products-potato patterns ( OR=0.71, 95% CI: 0.51-0.97). The decrease in the 2 h PBG control probability was related to fruit-aquatic products-potato patterns ( OR=0.60, 95% CI: 0.40-0.90). The increased probability of FPG and 2 h postprandial glucose control were both related to vegetable-grain pattern ( OR=1.41, 95% CI: 1.03-1.94; OR=1.68, 95% CI: 1.13-2.51) and egg-milk-bean pattern ( OR=1.75, 95% CI: 1.25-2.46; OR=1.56, 95% CI: 1.00-2.42). Compared with the Q4 group of egg-milk-bean pattern, the FPG control rate of the combination of "fruit-aquatic products-potato pattern ( Q4 group), vegetable-grain pattern ( Q2 group), egg-milk-bean pattern ( Q3 group)" was higher ( OR=6.79, 95% CI: 1.15-40.23, P=0.035). Compared with the Q4 group of vegetable-grain pattern, the combination of "fruit-aquatic products-potato pattern ( Q4 group), vegetable-grain pattern ( Q3 group), egg-milk-bean pattern ( Q2 group), oil-salt pattern ( Q2 group)" had higher control rate of 2 h PBG ( OR=12.78, 95% CI: 1.26-130.05, P=0.031). Conclusions:A proper combination of dietary patterns and dietary patterns are more conducive to the control of FPG and 2 h PBG in T2DM patients managed in the communities of Wuhan and Changshu. Patient nutrition education should be strengthened, and the food-matching ability of patients should be improved.
