Non-rigid registration plays an important role in medical image analysis. U-Net has been proven to be a hot research topic in medical image analysis and is widely used in medical image registration. However, existing registration models based on U-Net and its variants lack sufficient learning ability when dealing with complex deformations, and do not fully utilize multi-scale contextual information, resulting insufficient registration accuracy. To address this issue, a non-rigid registration algorithm for X-ray images based on deformable convolution and multi-scale feature focusing module was proposed. First, it used residual deformable convolution to replace the standard convolution of the original U-Net to enhance the expression ability of registration network for image geometric deformations. Then, stride convolution was used to replace the pooling operation of the downsampling operation to alleviate feature loss caused by continuous pooling. In addition, a multi-scale feature focusing module was introduced to the bridging layer in the encoding and decoding structure to improve the network model's ability of integrating global contextual information. Theoretical analysis and experimental results both showed that the proposed registration algorithm could focus on multi-scale contextual information, handle medical images with complex deformations, and improve the registration accuracy. It is suitable for non-rigid registration of chest X-ray images.

Objective:
This study’s objective is to assess the efficacy and safety of Pulsed Magnetic Therapy System (PMTS) in improving insomnia disorder.
Methods:
Participants with insomnia disorder were randomly assigned to receive either PMTS or sham treatment for four weeks (n= 153; PMTS: 76, sham: 77). Primary outcomes are the Insomnia Severity Index (ISI) scores at week 0 (baseline), 1, 2, 3, 4 (treatment), and 5 (follow-up). Secondary outcomes are the Pittsburgh Sleep Quality Index at baseline and week 4, and weekly sleep diary-derived values for sleep latency, sleep efficiency, real sleep time, waking after sleep onset, and sleep duration.
Results:
The ISI scores of the PMTS group and the sham group were 7.13±0.50, 11.07±0.51 at week 4, respectively. There was a significant group×time interaction for ISI (F3.214, 485.271=24.25, p<0.001, ηp 2=0.138). Only the PMTS group experienced continuous improvement throughout the study; in contrast, the sham group only experienced a modest improvement after the first week of therapy. At the end of the treatment and one week after it, the response of the PMTS group were 69.7% (95% confidence interval [CI]: 58.6%–79.0%), 75.0% (95% CI: 64.1%–83.4%), respectively, which were higher than the response of the sham group (p<0.001). For each of the secondary outcomes, similar group×time interactions were discovered. The effects of the treatment persisted for at least a week.
Conclusion
PMTS is safe and effective in improving insomnia disorders.

Background Occupational pneumoconiosis is the most common occupational disease in Qinghai Province and China. From the perspective of public health, it is important to assess the disease burden using disability-adjusted life years (DALY) and economic losses. Objective To evaluate the disease burden of occupational pneumoconiosis in Qinghai Province, and to provide a basis for the formulation and implementation of relevant prevention and control strategies. Methods Based on the registered data, a database of occupational pneumoconiosis cases confirmed and reported in Qinghai Province was established. The survival status and death dateof occupational pneumoconiosis patients from 2015 to 2019 were confirmed by on-site visit, telephone survey, matching search of Death Information Registration and Management System, and consulting other departments. The life loss due to occupational pneumoconiosis from 2015 to 2019 was assessed using DALY as an indicator and data from the Global Burden of Disease 2019 (GBD 2019) study. Inpatients with officially diagnosed occupational pneumoconiosis from a hospital in Qinghai Province in 2019 were selected as study subjects, the direct economic loss was evaluated with hospitalization expenses, and the indirect economic loss due to occupational pneumoconiosis in Qinghai Province in 2019 was calculated by human capital approach. Results From 2015 to 2019, 505 new cases of occupational pneumoconiosis were reported in Qinghai Province, and there were 348 death cases. Prevalent cases and years lost due to disability (YLD) due to occupational pneumoconiosis were increased, while DALY and years of life lost (YLL) due to occupational pneumoconiosis decreased firstly and then increased. In each year, there were 87% or more of the DALY, YLL, or YLD attributed to silicosis and coal workers' pneumoconiosis. In 2019, the occupational pneumoconiosis-associated DALY was 2173.55 person years. The total hospitalization expense incurred by 42 inpatients with occupational pneumoconiosis was 1256345.19 yuan. The total hospitalization expense and average daily cost of the inpatients with stageⅡand Ⅲ pneumoconiosis were higher than that of the inpatients with stageⅠ (P<0.05), and the hospitalization expense was higher in the ≥60 years age group than in the <60 years age group (P<0.05). In 2019, the indirect economic burden incurred by occupational pneumoconiosis in Qinghai Province was 44108581.65 yuan, and accounted for 0.15‰ of the gross domestic product (GDP) of the province. Conclusion The disease burden associated with occupational pneumoconiosis in Qinghai Province are outstanding. Silicosis and coal workers' pneumoconiosis are the key contributors. Targeted intervention measures including dust hazard control, enterprise management, follow-up and rehabilitation management of pneumoconiosis should be taken to prevent and control the occurrence and progression of pneumoconiosis and alleviate disease burden of pneumoconiosis.

Sleep deprivation (SD) has a profound impact on the central nervous system, resulting in an array of mood disorders, including depression and anxiety. Despite this, the dynamic alterations in neuronal activity during sleep deprivation have not been extensively investigated. While some researchers propose that sleep deprivation diminishes neuronal activity, thereby leading to depression. Others argue that short-term sleep deprivation enhances neuronal activity and dendritic spine density, potentially yielding antidepressant effects. In this study, a two-photon microscope was utilized to examine the calcium transients of anterior cingulate cortex (ACC) neurons in awake SD mice in vivo at 24-hour intervals. It was observed that SD reduced the frequency and amplitude of Ca2+ transients while increasing the proportions of inactive neurons. Following the cessation of sleep deprivation, neuronal calcium transients demonstrated a gradual recovery. Moreover, whole-cell patch-clamp recordings revealed a significant decrease in the frequency of spontaneous excitatory post-synaptic current (sEPSC) after SD. The investigation also assessed several oxidative stress parameters, finding that sleep deprivation substantially elevated the level of malondialdehyde (MDA), while simultaneously decreasing the expression of Nuclear Factor erythroid 2-Related Factor 2 (Nrf2) and activities of Superoxide dismutase (SOD) in the ACC. Importantly, the administration of gallic acid (GA) notably mitigated the decline of calcium transients in ACC neurons. GA was also shown to alleviate oxidative stress in the brain and improve cognitive impairment caused by sleep deprivation. These findings indicate that the calcium transients of ACC neurons experience a continuous decline during sleep deprivation, a process that is reversible. GA may serve as a potential candidate agent for the prevention and treatment of cognitive impairment induced by sleep deprivation.

ObjectiveTo compare the differences in resistance and structure of skin between acupoints and non-acupoints, and to study the difference in skin permeability characteristics of Corydalis Rhizoma total alkaloid patches (CTTP) after administration at Shenque acupoint and non-acupoint, so as to provide experimental support for its clinical acupoint application to prevent and treat chronic pain. MethodTaking corydaline (CD), tetrahydropalmatine (THP) and corydalis L (CDL) as evaluation indexes, and the quantitative analysis was carried out by high performance liquid chromatography (HPLC). The mobile phase was methanol-0.04 mol·L-1 phosphoric acid aqueous solution (70∶30, pH 6.0 adjusted with triethylamine), the detection wavelength was 281 nm. In vitro transdermal test in Franz diffusion cell and in vivo transdermal test were used to study the skin permeability characteristics of CTTP through Shenque acupoint and non-acupoint administration. At the same time, the skin resistance between Shenque acupoint and non-acupoint was measured before and after the administration, and the distribution of the drug in each layer of the skin was compared by freezing sectioning, and visual verification was performed with fluorescence inverted microscope. ResultAfter 24 h of administration, the results of in vivo and in vitro experiments showed that the cumulative permeation and retention of CD, THP and CDL at Shenque acupoint skin were higher than those at non-acupoint skin (P<0.05, P<0.01), the skin resistance of Shenque acupoint was lower than that of non-acupoint at all time points. The fluorescence microscopic observation results showed that the drug content of each layer of the skin was all Shenque acupoint>non-acupoint, indicating that the skin of Shenque acupoint had better effect on drug penetration and storage than non-acupoint. ConclusionThe 24 h cumulative permeation and retention of CTTP in Shenque acupoint skin are higher than those in non-acupoint skin, and the mechanism may be related to the thin skin, low electrical resistance and large number of hair follicle bodies at Shenque acupoint.

Objective:To investigate the protective effect of hyperbaric oxygen therapy(HBOT)on myocardial fibrosis and oxidative stress induced by D-galactose(D-gal)in senescent model mice and its possible mechanism.Methods:Three-month-old male Kunming mice(n=27)were randomized into control, D-gal, and D-gal + HBOT groups.The control group received subcutaneous sterilized saline(5 ml · kg -1· d -1)for 8 weeks; the remaining 2 groups received subcutaneous D-gal(200 mg · kg -1· d -1)for 8 weeks. The D-gal + HBOT group underwent HBOT intervention at week 7~8.At the end of the experiment, the histopathological changes were analyzed by hematoxylin-eosin(HE)staining, and the fibrosis changes were analyzed by Masson staining and Sirius red staining.Oxidative stress kit was used to detect catalase(CAT), total superoxide dismutase(T-SOD)activity and malon-di-aldehyde(MDA)content in serum of mice.Western blotting was used to detect the expression levels of the aging-related proteins p53 and p16 in mouse heart tissue, the heart-function-related proteins atrial natriuretic peptide(ANP)and brain natriuretic peptide(BNP), and the oxidative stress-related protein superoxide dismutase 1(SOD1), superoxide dismutase 2(SOD2)and catalase(CAT). Results:Cardiac morphologic staining indicated that as compared with the control group, mice of D-gal group exhibited features of senescence and the increased fibrosis area, and senescence and fibrosis were obviously improved after HBOT intervention as compared with the D-gal group.The findings of the oxidative stress kit measurement indicated that as compared with the control group, the D-gal group had markedly decreased activities of CAT and T-SOD, significantly increased MDA content in the serum.After HBOT treatment, as compared with d-gal group, serum CAT and T-SOD activities were increased, while MDA content was decreased( F=126.85, 32.89, 157.50, all P<0.05).Furthermore, as compared with the control group, the D-gal group had obviously increased contents of p53, p16, ANP and BNP, while the content of CAT, SOD1 and SOD2 were obviously decreased.After HBOT intervention, as compared with the D-gal group, the contents of p53, p16, ANP、BNP were reduced, while the content of CAT, SOD1 and SOD2 were increased( F=36.37, 14.81, 23.28, 58.41, 12.79, 80.08, 6.63, all P<0.05). Conclusions:HBOT intervention could protects against cardiac injury in aging mice, which may be related to attenuating myocardial fibrosis, inducing the expression of antioxidant enzymes, and reducing oxidative stress.

Objective:To explore the relationship between disease uncertainty, coping style, and self-perceived burden (SPB) in patients with lower extremity deep vein thrombosis (DVT) .Methods:Totally 280 patients with lower extremity DVT who were hospitalized in the Department of Vascular Surgery of three ClassⅢ Grade A hospitals in Cangzhou from September 2020 to April 2021 were selected by convenience sampling and investigated with the general information questionnaire, Medical Coping Style Questionnaire, Self-Perceived Burden Scale (SPBS) , Medical Coping Modes Questionnaire (MCMQ) , and Mishel's Uncertainty in Illness Scale (MUIS-A) . Pearson correlation was used to analyze the correlation between variables. A total of 280 questionnaires were distributed in this study, and 262 valid questionnaires were recovered, with an effective recovery rate of 93.6%.Results:The SPB score of the 262 patients with lower extremity DVT was (28.83±7.43) ; disease uncertainty, avoidance, and yielding were positively correlated with the patients' SPB ( r=0.651, 0.477, 0.469; P<0.01) , while facing was negatively correlated with SPB ( r=-0.485, P<0.01) . The path analysis revealed that avoidance and yielding played a partial mediating effect between disease uncertainty and SPB, accounting for 14.6% of the total path effect. Conclusions:Disease uncertainty can indirectly affect SPB in patients with lower extremity DVT through avoidance and yielding. Clinical medical staff should formulate targeted intervention and health guidance strategies to improve patients' disease cognition and coping ability, and reduce their SPB.
