Silicone implant leakage and capsular calcification are potential complications following breast augmentation with silicone implants. This article presents a case of silicone implant leakage accompanied by capsular calcification following breast augmentation surgery. A 51-year-old female presented with self-reported breast hardening over 21 years after undergoing bilateral silicone implant augmentation mammoplasty and sought medical attention at the Department of Plastic Surgery, the First Affiliated Hospital of Dalian Medical University in 2019. Physical examination revealed eggshell-like hardening of the implants with Baker grade Ⅱ capsular contracture. CT scans demonstrated capsular calcification, leading to bilateral explantation and capsulectomy. Intraoperative findings showed calcified capsules with gelatinous material adherent to the surface. Postoperative compositional analysis confirmed calcium phosphate deposits in the calcified lesions. During the 6-year follow-up, the patient remained asymptomatic without breast pain, new masses, or impaired upper limb mobility. The incisions healed well with no sensory abnormalities. Literature review suggested that implant leakage may result from either long-term mechanical irritation secondary to capsular calcification or occult silicone leakage.

Objective:To explore the pain sensations and experiences of patients with post-stroke hemiplegic shoulder pain, and to provide reference for the formulation of intervention plans.Methods:Objective sampling method was used to conduct semi-structured interviews on 15 patients with post-stroke hemiplegic shoulder pain in the department of neurology and rehabilitation department of Wuhan No.1 Hospital from January to March 2024. The interview outline was established based on the information-knowledge-attitude-practice (IKAP) theory, and the data were analyzed, summarized and extracted by Colaizzi 7-step analysis method.Results:According to the four core components of the IKAP theory, ten themes were extracted. The information and knowledge included the neglect of the importance of early management for hemiplegic shoulder pain, the lack of understanding of the relevant knowledge about hemiplegic shoulder pain, and the use of restricted or incorrect attribution methods in relation to hemiplegic shoulder pain. The attitude included a perception of pain as uncontrollable, the suppression of pain expression, the concern regarding the persistent presence of pain, and the experience of negative emotions. The practice included the adverse effects stemming from hemiplegic shoulder pain, the strategies employed to cope with hemiplegic shoulder pain, and the expectation of multifaceted social support.Conclusions:Patients with post-stroke hemiplegic shoulder pain bear many burdens and have needs in terms of pain experiences. Healthcare professionals need to strengthen pain health education and guidance, help patients develop correct pain cognition and beliefs, refine the pain management system, assist patients in establishing a diverse social support system, enhance their pain coping abilities, and comprehensively promote the rehabilitation of the disease.

Objective To investigate the effects of formulated granules of Tianma Gouteng Yin(TGY)on motor deficits in a mouse model of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)-induced subacute Parkinson's disease(PD)and explore the possible molecular mechanisms.Methods Ninety C57BL/6 mice were randomized equally into 6 groups,including a control group,a PD model group,a NEC-1(6.5 mg/kg)treatment group,two TGY treatment groups at 5 and 2.5 g/kg,and a Madopar(76 mg/kg)treatment(positive control)group.Mouse models of PD were established by intraperitoneal injection of MPTP(30 mg/kg)for 5 consecutive days with the corresponding treatments for 15 days.The mice were randomly selected for motor function tests.Western blotting was used to detect the changes in expressions of TH,α-syn,RIPK1,RIPK3 and MLKL in the striatum of the mice.Network pharmacology analysis and molecular docking studies were performed to explore TGY-mediated regulation of the necroptosis pathway for PD treatment.Results Compared with those in the control group,the PD model mice exhibited obvious motor deficits with significantly increased α-syn protein expression and lowered TH protein expression in the striatum.Treatment with NEC-1 obviously improved motor deficits,inhibited the necroptosis pathway,and alleviated the changes in TH and α-syn proteins in PD mice.Network pharmacology and molecular docking analyses suggested that the therapeutic effect of TGY in PD was associated with the modulation of RIPK1,a key protein in the necroptosis pathway.In PD mouse models,TGY treatment at the two doses significantly improved motor deficits of the mice,increased TH expression,and decreased the expressions of α-syn and necroptosis-related proteins in the striatum.Conclusion TGY can effectively inhibit the necroptosis pathway,increase TH expression and decrease α-syn expression in the striatum to improve motor deficits in PD mice.
