Objective:To design a vest-type breast dressing bra and explore its application effect in the external application of traditional Chinese medicine therapy for patients with granulomatous lobular mastitis(GLM).Methods:A randomized controlled study was conducted, utilizing convenience sampling to select female patients with 122 GLM who underwent their first topical medication treatment in the Breast Department of Guangdong Provincial Hospital of Traditional Chinese Medicine between January and May 2023. The patients were divided into a control group and an observation group, with 61 patients in each, using a random number table. Following medication application, patients in the control group used a regular sports bra to secure the medication, while patients in the observation group used a custom-designed vest-style breast medication bra for the same purpose. Three hours after the intervention, comparisons were made between the two groups in terms of the incidence of medication detachment, medication displacement, clothing contamination, patient satisfaction, and safety.Results:Both groups of patients completed the study. The age of the observation group was (32.18 ± 5.50) years old, while the age of the control group was (33.66 ± 5.20) years old. Three hours after the intervention, the incidence of medication detachment, medication displacement, clothing contamination in the observation group were 3.28% (2/61), 6.56% (4/61), and 8.20% (5/61), which were lower than those in the control group with 18.03% (11/61), 26.23% (16/61), and 67.21% (41/61), respectively. The differences were statistically significant ( χ2=6.97, 8.61, 45.23; all P<0.05). The satisfaction level of patients towards the bra in the observation group was (4.43 ± 0.85) points, higher than that of the control group (3.85 ± 1.08) points, with a statistically significant difference ( t=3.30, P<0.05). The incidence rates of skin allergic reactions were 3.28%(2/61) and 4.92%(3/61) in the observation group and the control group, respectively, with no statistically significant difference ( P>0.05). Conclusions:The vest-type breast dressing bra designed in this study can properly secure the medicinal paste, reduce the rate of medication detachment, medication displacement, clothing contamination, and enhance patient satisfaction. It facilitates the external application of traditional Chinese medicine for patients with GLM and is worthy of clinical promotion.

Objective To observe the value of contrast-enhanced ultrasound(CEUS)for diagnosing splenic lymphoma.Methods Eighteen patients with pathologically confirmed splenic lymphoma were retrospectively collected.The routine ultrasound and CEUS manifestations of lesions were observed,and the diagnostic accuracy of these two methods for diagnosing splenic lymphoma were compared.Results Among 18 cases,conventional ultrasound showed single lesion in 8(8/18,44.44％)and multiple lesions in 10 cases(10/18,55.56％).The maximum diameter of lesions was(5.43±2.03)cm.For the largest lesion(target lesion)in 18 cases,5(5/18,27.78％)were found with very low echo,11(11/18,61.11％)with low echo and 2(2/18,11.11％)with mixed echo.The internal echo was uneven in 10 lesions(10/18,55.56％)while uniform in 8 lesions(8/18,44.44％),8(8/18,44.44％)shaped regularly but 10(10/18,55.56％)irregularly,15(15/18,83.33％)with clear and 3(3/18,16.67％)with unclear boundaries.CDFI showed blood flow signals in 10(10/18,55.56％)but not in 8 lesions(8/18,44.44％).During CEUS of 18 target lesions,no enhancement was detected in 1 lesion(1/18,5.56％),peripheral to central enhancement,central to peripheral enhancement and synchronous enhancement was observed in 12(12/18,66.67％),2(2/18,11.11％)and 3 lesions(3/18,16.67％),respectively,which at the peak mainly presented as low(8/18,44.44％)or high(7/18,38.89％)enhancement,while no enhancement or equal enhancement was noticed in 1(1/18,5.56％)and 2(2/18,11.11％)lesions,respectively.Uniform and uneven distribution of contrast agents was found in 5(5/18,27.78％)and 12(12/18,66.67％)lesions,respectively,while 1 lesion(1/18,5.56％)without distribution of contrast agents.Annular and dendritic enhancement in peripheral area was observed in 7(7/18,38.89％)and 5 lesions(5/18,27.78％),while nodular enhancement(3/18,16.67％)or no enhancement(3/18,16.67％)was noticed each in 3 lesions.The scope enlarged after enhancement in 1 lesion(1/18,5.56％),while 17 lesions(17/18,94.44％)did not increase significantly.In the late stage of enhancement,16 lesions(16/18,88.89％)showed low enhancement,while 2(2/18 11.11％)showed no enhancement.Among 18 target lesions,CEUS showed blood supply in 17 lesions(17/18,94.44％),while no blood supply was found in 1 lesion(1/18,5.56％).CEUS correctly diagnosed 11 cases of splenic lymphoma,with diagnostic accuracy of 61.11％(11/18),higher than that of conventional ultrasound([4/18,22.22％],P=0.020).Conclusion CEUS had important clinical value for diagnosing splenic lymphoma.

Objective To investigate the effect of Erianin on inflammation by regulating thioredoxin interaction protein/NOD-like receptor thermal protein domain associated protein 3(TXNIP/NLRP3)signaling pathway in rats with diabetes peripheral neuropathy(DPN).Methods SD rats were divided into normal control(NC)group,DPN group,Erianin 10 mg/kg(Eri 10)group,Erianin 40 mg/kg(Eri 40)group,Eri 40+pLVX-NC group,and Eri 40+TXNIP overexpression vector(Eri 40+pLVX-TXNIP)group,10 in each group.BG,IL-18,IL-1β,IL-10,reactive oxygen species(ROS)and nerve motor and sensory conduction velocity were detected in each group.HE was used to detect the histopathological changes of sciatic nerve.The mRNA and protein expressions of TXNIP,NLRP3 and Caspase-1 were detected by qRT-PCR and Western blot.Results Compared with NC group,BG,IL-18,IL-1β,ROS,mRNA and protein expressions of TXNIP,NLRP3 and Caspase-1 were increased(P<0.05),while IL-10,motor and sensory conduction velocity were decreased in DPN group(P<0.05).BG,IL-18,IL-1β,ROS,mRNA and protein expressions of TXNIP,NLRP3 and Caspase-1 were decreased successively(P<0.05),while IL-10,motor and sensory conduction velocity were increased successively in DPN,Eri 10 and Eri 40 groups(P<0.05).Compared with Eri 40 and Eri 40+pLVX-NC groups,BG,IL-18,IL-1β,ROS,the mRNA and protein expressions of TXNIP,NLRP3 and Caspase-1 were increased(P<0.05),while IL-10,motor and sensory conduction velocity were significantly decreased in Eri 40+pLVX-TXNIP group(P<0.05).Conclusions Erianin can regulate TXNIP/NLRP3 signaling pathway to reduce inflammatory response and protect sciatic nerve in rats with DPN.

BACKGROUND:Ankle inversion injuries frequently occur during landing,injuring the anterior talofibular and calcaneofibular ligaments.Previous studies usually used indirect indicators,such as inversion angle,as an injury risk indicator,but epidemiological support is lacking.OBJECTIVE:To calculate anterior talofibular and calcaneofibular ligament strains using a three-dimensional multi-body foot model during a drop-landing and to investigate whether increasing the foot toe-out angle for landing would reduce the risk of inversion sprains.METHODS:Thirty-five participants with high sports demands[15 males and 20 females,age:(21.0±0.9)years,height:(176.2±8.8)cm,body mass:(71.6±12.8)kg]were recruited to perform a drop-landing test using a trapdoor device to simulate ankle inversion sprains.Two landing conditions were tested,i.e.,natural landing and toe-out landing.Kinematic data were collected using a 12-camera motion analysis system,the strains of the anterior talofibular and calcaneofibular ligaments were calculated using a three-dimensional rigid-body foot model.RESULTS AND CONCLUSION:From natural landing to toe-out landing conditions,the anterior talofibular ligament strain decreased[natural landing=(3.57±1.92)％,toe-out landing=(0.36±1.18)％,P＜0.001,Cohen's d=2.01),as was the calcaneofibular ligament strain[natural landing=(1.38±1.80)％,toe-out landing=(0.28±2.29)％,P=0.003,Cohen's d=0.81).It could be concluded that increasing foot toe-out angle reduces anterior talofibular and calcaneofibular ligament strains during drop-landing with ankle inversion,thereby reducing the potential of ankle inversion sprains.

Objective:This study aims to investigate the spillover effects of the Diagnosis-Related Groups payment reform on medical expenditures.Methods:Based on the medical record data of inpatients in a tertiary Grade A hospital in Wuhan,Hubei Province,the Difference-in-Differences method was applied to estimate the impact of the DRG reform on medical expenditures for non-local patients.Results:After the implementation of DRG payment,the total medical expenses(β=-0.13),out-of-pocket expenses(β=-0.22),drug expenses(β=-0.25),consumable expenses(β=-0.26)decreased significantly.Meanwhile,the reduction ranges of the level and proportion of out-of-pocket expenses for non-local inpatients were significantly larger than those for local inpatients.However,the reduction range of the proportion of drug expenses for non-local inpatients was significantly smaller than that for local inpatients.The gaps between the two groups in terms of the level of out-of-pocket expenses and the proportion of drug expenses gradually narrowed.Conclusion:The DRG payment reform has produced a significant spillover effect,leading to a decrease in the medical expense level and an improvement in the expense structure for non-local inpatients.However,the medical expenses of non-local inpatients remain relatively high.It is suggested to accelerate the inclusion of non-local inpatients in disease-specific payment management and strengthen the coordination between the hospital's internal operation management and the reform of medical insurance payment methods.

Head and neck squamous cell carcinoma （HNSCC） is one of the ten most common cancers worldwide and is one of the refractory cancers with a poor prognosis in otorhinolaryngology-head and neck surgery. Cetuximab is widely used in the clinical treatment of HNSCC and has been approved by the FDA as a first-line chemotherapeutic agent. However, its efficacy varies significantly among different individuals. Therefore, exploring the resistance mechanisms of cetuximab in the treatment of HNSCC and screening for sensitive populations are essential for the precision treatment of head and neck cancer. This article summarizes the research progress on cetuximab resistance mechanisms in HNSCC, and the main aspects include: alterations in epidermal growth factor receptor （EGFR） and its ligands, changes in downstream effectors of EGFR, bypass activation and crosstalk, epithelial-mesenchymal transition, epigenetic modifications, and immunosuppression in the tumor microenvironment.

Metabolites produced as intermediaries or end-products of microbial metabolism provide crucial signals for health and diseases, such as metabolic dysfunction-associated steatotic liver disease (MASLD). These metabolites include products of the bacterial metabolism of dietary substrates, modification of host molecules (such as bile acids [BAs], trimethylamine-N-oxide, and short-chain fatty acids), or products directly derived from bacteria. Recent studies have provided new insights into the association between MASLD and the risk of developing chronic kidney disease (CKD). Furthermore, alterations in microbiota composition and metabolite profiles, notably altered BAs, have been described in studies investigating the association between MASLD and the risk of CKD. This narrative review discusses alterations of specific classes of metabolites, BAs, fructose, vitamin D, and microbiota composition that may be implicated in the link between MASLD and CKD.
