Objective To analyze the economic cost of self-monitoring of gestational diabetes mellitus, and provide a basis for measuring the economic burden of gestational diabetes mellitus, and to provide a reference for the formulation of intervention development and the adjustment of resource allocation. Methods The individual economic cost of self-monitoring for gestational diabetes mellitus was measured based on a decision tree model, and the total economic cost of self-monitoring for gestational diabetes mellitus in Beijing was estimated. The uncertainty of the model parameters was analyzed using one-way sensitivity analysis. Results The average individual economic cost of gestational diabetes self-monitoring was 1184 RMB, and the individual cost incurred by choosing different types of blood glucose meters ranged from 403 to 18 000 RMB. The average individual economic cost of finger-stick blood glucose monitoring was 606 RMB and the average individual economic cost of continuous glucose monitoring was 2 374 RMB. The total economic cost of gestational diabetes self-monitoring in Beijing was 23.818 0 million RMB, and the total economic cost incurred by choosing different types of blood glucose meters ranged from 0.292 5 to 9.027 9 million RMB. The proportion of the finger-stick blood glucose monitoring had the greatest impact on the robustness of the results. Conclusion Finger-stick blood glucose monitoring is still the dominant self-monitoring method and is less costly than continuous glucose monitoring. Self-monitoring of pregnant women with gestational diabetes mellitus incurs certain economic cost and causes an economic burden on society.

Thyroid cancer is the most common malignant tumor of the head and neck, among which papillary thyroid carcinoma is the most common.

ObjectiveTo automatically measure the wrist range of motion using the somatosensory capture device Azure Kinect. MethodsAzure Kinect was used to recognize the spatial coordinates of human elbow, wrist, palm, fingertip and other joint points, and the best measurement posture was determined by orthogonal experiment. Holt's double-parameter exponential smoothing method and bone length constraint method were used to smooth the joint point data to eliminate the jitter. The average angle of multiple frames was calculated through the spatial vector relationship to realize the automatic measurement of wrist joint range of motion. From May to October, 2021, 5 times × 10 groups of measurement were performed on each subject of wrist joint of five healthy subjects using the above method. ResultsThe R1 of each subject of wrist joint was between 83 and 127, and the value was in the middle. This method contrasted well with measurements made on augmented reality ruler, 2D images (r > 0.990), and the maximum error was within 1.61°. ConclusionThe wrist joint angle measurement modality using Azure Kinect is consistent to conventional measurement modality, and can meet the requirements of real-time measurement.

Objective:To analysis the income and expenditure of HIV-positive pregnant women and the catastrophic health expenditure of their households in high AIDS endemic areas in Liangshan prefecture.Methods:From December 2018 to January 2019, a total of 250 pregnant women were recruited from 2 of 17 counties in Liangshan Prefecture, including 133 HIV-positive pregnant women and 117 HIV-negative pregnant women. The data, including basic information of pregnant women, basic information of the family, annual family income in 2017, annual family health expenditure in 2017, and maternal and child-related expenditure in 2017, were collected for analyzing the incidence of catastrophic health expenditure in the family.Results:The average annual income and average annual health expenditure of HIV-positive pregnant women households were 7 000 CNY and 2 000 CNY, while those of HIV-negative pregnant women households were 10 000 CNY and 3 000 CNY, respectively. Based on the criteria of 15%, 25% and 40%, the incidence of catastrophic health expenditure of HIV-positive pregnant households was 39.10%, 33.83% and 27.82%, with average differences of 34.84%, 31.17% and 26.65%, respectively, while that of HIV-negative pregnant women households was 38.46%, 33.33% and 23.93%, with average differences of 31.68%, 28.35% and 24.22%, respectively.Conclusion:The incidence of catastrophic health expenditure of pregnant households in high AIDS endemic areas in Liangshan prefecture is high. The incidence of HIV-positive families is slightly higher than that of HIV-negative families. We suggest that medical insurance compensation in Liangshan prefecture should be improved to reduce the impact of catastrophic health expenditure.

Objective To observe the changes in the transforming growth factor-beta 1 (TGF-β1 ) mRNA expression in the lung in a dog model of cardiopulmonary bypass(CPB)-induced acute lung injury. Methods Thirty-six healthy adult mongrel dogs of both sexes weighing 15-16 kg were randomly assigned into control group and CPB group ( n = 18 each) . Lung injury was produced by CPB according to the method described by Williams. Six animals were killed at each of the following time points: before CPB (T0 ) and 30 and 60 min after termination of CPB (T1 , T2) in each group. Lung specimens were obtained for microscopic examination and determination of TGF-β1 mRNA expression (by RT-PCR) and MDA content. The lungs were lavaged and the protein concentration in the brancho-alveolar lavage fluid (BALF) was determined and pulmonary permeability index (PPI) was calculated. Results Microscopic examination showed massive inflammatory cell infiltration, alveolar capillary dilatation, congestion, widened alveolar septum, massive RBC in the alveolar space and focal atelectasis in the lung in CPB group. The TGF-β1 mRNA expression and MDA content and PPI were significantly higher in CPB group than in control group. The TGF-β1 mRNA expression and MDA was positively correlated to PPI (MDA: r = 0.867, P < 0.01; PPI: r = 0.821, P < 0.01) . Conclusion TGF-β1 mRNA expression in the lung is significantly up-regulated after CPB and is an important factor contributing to CPB-induced acute lung injury.
