Objective To explore the correlation between brachial and ankle pulse wave conduction velocity(baPWV)and cardiac structure and function in patients with type 2 diabetes mellitus(T2DM).Methods A total of 443 patients with T2DM who were treated in The Endocrinology Department of Gansu Provincial People's Hospital were enrolled in this study from June 2022 to October 2023.All the patients were divided into simple T2DM group(T2DM,baPWV<1400 cm/s,n=221)and atherosclerosis group(AS,baPWV≥1400 cm/s,n=222)based on baPWV.The cardiac ultrasound diagnostic instrument was used to record left ventricular ejection fraction(LVEF),end diastolic left ventricular diameter(LVd),end diastolic interventricular septal thickness(IVSd),end diastolic left ventricular posterior wall thickness(LVPWd),ratio of early to late diastolic peak velocity of mitral valve annulus(E/A),and ratio of early diastolic peak velocity of mitral valve orifice to early diastolic peak velocity of mitral valve annulus(E/E').Results Age,DM duration,SBP,DBP,HbA1c,TG,ABI,LVEF,IVSd,LVPWd,E/A<1,E/E'＞14,were higher in AS group than in T2DM group(P<0.05 or P<0.01).Spearman correlation analysis shows that E/A<1 was positively correlated with age,DM duration,BMI,SBP,DBP,and ABI(P<0.05 or P<0.01),while negatively correlated with baPWV(P<0.01).Pearson correlation analysis shows that LVPWd was positively correlated with age,DM duration,BMI,SBP,DBP,baPWV,and Scr(P<0.05 or P<0.01).Logistic regression analysis shows that baPWV,ABI,and SBP were the influencing factors for left ventricular diastolic dysfunction.The analysis of the working characteristic curve of the subjects shows that the area under the curve of baPWV,SBP and ABI for predicting left ventricular diastolic dysfunction is 0.647,0.643,and 0.624,with the best cutoff points being 1398.5 cm/s,125.5 mmHg,and 1.107.Conclusions baPWV is closely related to cardiac structure and function in T2DM patients.As baPWV increases,the risk of left ventricular diastolic insufficiency and hypertrophy rises.

Objective:To compare the dynamic changes of transcutaneous partial pressure of carbon dioxide (PtCO 2) and treatment effect of non-invasive intermittent nebulization and non-invasive simultaneous nebulization in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). Methods:This was a randomized parallel controlled trial study. A total of 70 patients with acute exacerbation of COPD in Changzhou First People′s Hospital from October 2021 to September 2022 were selected by convenience sampling method, and divided into control group and experimental group by randomized digits table method with 35 cases in each group. The control group was given non-invasive intermittent oxygen-driven nebulization, and the experimental group was given non-invasive simultaneous oxygen-driven nebulization. The PtCO 2 values at 0, 5, 10, 15 min (the end point of atomization) of the 2 groups were observed, the daily arterial blood gas analysis indexes (mainly including PaCO 2, PaO 2 and pH) were recorded, and the clinical pulmonary infection score and the self-assessment score of COPD patients were recorded before treatment, on the 4th and 7th day of treatment. Results:Finally, 33 patients were included in both the control group and the experimental group. There were 25 males and 8 females in the control group, aged (75.33 ± 8.24) years old. There were 25 males and 8 females in the experimental group, aged (72.39 ± 8.56) years old. The PtCO 2 values at 0, 5, 10, 15 min in the control group were (63.83 ± 12.47), (64.40 ± 12.57), (65.42 ± 13.77), (66.62 ± 14.59) mmHg (1 mmHg=0.133 kPa). There were statistically significant differences in PtCO 2 at all time points ( F=8.05, P<0.01). Further pairwise comparison by Sidak method showed that there were statistically significant differences in PtCO 2 at 15 min compared with 0, 5, 10 min (all P<0.05). The PtCO 2 values at 0, 5, 10, 15 min in the experimental group were (67.62 ± 11.89), (67.15 ± 12.12), (67.82 ± 12.22), (68.15 ± 12.09) mmHg. There was no statistically significant difference in PtCO 2 at all time points ( F=2.00, P>0.05). The PaCO 2 and pH value of the two groups were improved with the treatment time, the control group had a statistically significant difference on the 4th day of treatment compared with before treatment ( P<0.05), while the experimental group on the second day of treatment compared with before treatment ( P<0.05). Conclusions:Both kinds of nebulization have achieved good therapeutic effects, but non-invasive simultaneous nebulization can better maintain the stability of PtCO 2 in the process of nebulization with higher safety, and can improve the arterial blood gas index PaCO 2 and pH value of patients earlier, which is a more suitable nebulization method for the combination of non-invasive ventilation and nebulization, especially for patients with hypercapnia.

OBJECTIVE: We aimed to understand the willingness and barriers to the acceptance of tuberculosis (TB) preventive treatment (TPT) among people with latent TB infection (LTBI) in China. METHODS: A multicenter cross-sectional study was conducted from May 18, 2023 to December 31, 2023 across 10 counties in China. According to a national technical guide, we included healthcare workers, students, teachers, and others occupations aged 15-65 years as our research participants. RESULTS: Overall, 17.0% (183/1,077) of participants accepted TPT. There were statistically significant differences in the acceptance rate of TPT among different sexes, ages, educational levels, and occupations ( P < 0.05). The main barriers to TPT acceptance were misconceptions that it had uncertain effects on prevention (57.8%, 517/894), and concerns about side effects (32.7%, 292/894). CONCLUSION An enhanced and comprehensive understanding of LTBI and TPT among people with LTBI is vital to further expand TPT in China. Moreover, targeted policies need to be developed to address barriers faced by different groups of people.

Objective:To evaluate the clinical efficacy of arthroscopic side-to-side suture with remnants preserved in repair of transtendinous rotator cuff tears.Methods:A retrospective study was conducted to analyze the data of 17 patients who had been treated by arthroscopic side-to-side suture with remnants preserved for transtendinous rotator cuff tear caused by trauma at Sports Medicine Center, The Second Hospital Affiliated to Inner Mongolia Medical University from January 2017 to January 2020. There were 11 males and 6 females with an age of (47.9±8.3) years and a duration from injury to surgery of (50.4±21.3) d. Recorded were range of motion and muscle strength of the shoulder, University of California at Los Angeles (UCLA) shoulder function score, Constant-Murley shoulder function score, visual analogue scale (VAS) pain score, re-tears and complications before operation and at the last follow-up.Results:The 17 patients were followed up for (16.5±3.5) months after operation. Retear of the rotator cuff occurred in 2 patients after operation while MRI showed good healing of the rotator cuff in the other patients with no such postoperative complications as infection or wound dehiscence. At preoperation and the last follow-up, respectively, the range of shoulder flexion was 152.9°±8.5° and 172.4°±5.6°, the abductor muscle strength 3.5 (2.6, 4.1) kg and 6.9 (6.3, 8.3) kg, the external rotator muscle strength (3.8±1.0) kg and (5.9±1.6) kg, the internal rotator muscle strength 3.9 (3.4,4.7) kg and 5.2 (4.5,5.9) kg, the UCLA score (13.2±1.9) points and (30.9±2.4) points, the Constant score (40.1±2.8) points and (86.1±4.6) points, and the VAS score (6.7±0.8) points and (0.9±0.6) points, all showing a significant difference between preoperation and the last follow-up ( P<0.05). Conclusion:In repair of transtendinous rotator cuff tears, arthroscopic side-to-side suture with remnants preserved can lead to significantly improved clinical outcomes in range of motion, muscle strength, functional recovery and pain relief.
