Factors associated with resorption of calcific deposits in the shoulder with extracorporeal shock wave therapy.

BACKGROUND: Focused extracorporeal shock wave therapy (FSWT) is effective for treating calcific tendinitis of the shoulder. However, only a few reports exist on the factors related to calcium resorption after FSWT. Thus, this study aimed to investigate the factors associated with calcium resorption. METHODS: In 117 shoulders with chronic calcific rotator cuff tendinitis, FSWT was administered nine times once every 2 weeks (a total of 16 weeks). After nine sessions of FSWT, the shoulders were radiographed and categorized into complete resorption (CR) and incomplete resorption (ICR) groups. Evaluated parameters included age, duration of disease, Gärtner classification, size of calcium deposits, presence of blood flow around calcium deposits using the Doppler function of the ultrasound imaging system, Japanese Orthopaedic Association (JOA) score, University of California at Los Angeles score, disability of the arm, shoulder, and hand (UCLA) score, and tenderness. RESULTS: The CR group included 93 shoulders (79.4%) and the ICR group included 24 shoulders (20.6%). In the two-arm comparison, CR showed significantly longer disease duration (P=.012) and high tenderness (P=.0013). Blood flow around calcium deposits was observed in 79.5% of shoulders in the CR group (P<.0001) and 29.1% in the ICR group. Type 1 Gärtner classification (P=.0009) was observed in 28 shoulders (30.1%) in the CR group and 17 shoulders (70.8%) in the ICR group. The two groups had no significant differences in age, size of calcium deposits, JOA score, or UCLA score. Multiple logistic regression analysis was performed using the following items that showed significant differences: absence of blood flow (odds ratio [OR], 8.51, 95% confidence interval [CI]: 2.24-22.8), Gärtner classification (OR, 5.60, 95%CI: 1.73-13.3), and duration of disease (OR, 1.06, 95%CI: 0.97-1.26). Longer disease duration, Gärtner type 1, and absence of blood flow around calcium deposits resulted in difficulty in calcium resorption. CONCLUSION: Patients with Gärtner type 1 with prolonged disease duration and absence of blood flow around calcium deposits may have difficulty in achieving complete resorption.

Evaluating the role of urine chemistry in shock wave lithotripsy outcomes.

AIM: Extracorporeal Shock Wave Lithotripsy (ESWL) is a commonly used method for the noninvasive treatment of kidney stones. However, achieving optimal treatment outcomes and minimizing potential damage to the kidney necessitates careful consideration for the total amount of energy utilized. This study aims to investigate whether urine pH and urine specific gravity have an impact on the total amount of energy applied during SWL. PATIENTS AND METHODS: Between January 2023 and December 2023, 129 patients with renal stones underwent SWL in our department using the Storz Medical Modulith Inline lithotripter. Stone-free rates, complications, and the impact of patient, urine, and stone characteristics on energy use were analyzed. Urine samples were analyzed for pH and specific gravity. Stone characteristics, including size, HU, and skin-to-stone distance, were recorded. The obtained data were evaluated regarding the possible relationship between the total energy amount (determined as a risk factor) and the age, BMI, urine pH, urine specific gravity, stone size, HU, and skin-to-stone distance by using the Pearson correlation coefficient. p-value of < 0.05 was considered statistically significant. RESULTS: Evaluation of our findings revealed a negative linear relationship between total amount of energy used and the urine pH, indicating a decrease in the total energy amount as urine pH shifts towards alkaline values (p = 0.038; p < 0.05). However, no statistically significant relationship was observed between age, BMI, urine specific gravity, stone size, HU, and skin-to-stone distance and the total energy amount. CONCLUSIONS: Our findings demonstrated a significant relationship between urine pH and the total amount of energy applied during SWL sessions, suggesting the need for further prospective research to better understand the possible association between these two parameters. Such investigations could contribute to the development of more reasonable and effective strategies for kidney stone treatment in an attempt to minimize the potential kidney damage.

Clinical Efficacy and Safety of Low-Energy Extracorporeal Shock Wave Therapy for Various Conditions of Deep Dermal and Subdermal Fibrosis.

BACKGROUND: Extracorporeal shock wave therapy (ESWT) enhances extracellular matrix remodeling and tissue regeneration by promoting growth factor release, regulating blood and lymphatic flows, and reducing fat and fibrotic tissues. Focused shock wave therapy (F-SWT), radial shock wave therapy (R-SWT), and combined F-SWT and R-SWT have been used to deliver different patterns of shock energy depending on the characteristics of the target lesions. METHODS: We investigated the efficacy and safety of ESWT in patients with dermal and subdermal fibrosis. Fifty-two patients treated with F-SWT and/or R-SWT for dermal and subdermal fibrosis caused due to various reasons were retrospectively analyzed by reviewing their medical records, clinical images, and ultrasound study images. RESULTS: The mean number of pulses administered for F-SWT on the cheek, temple, and chin were 2600.0 ± 1040.8 shocks/session and for R-SWT were 5080.0 ± 2234.6 pulses/session, and the number of treatment sessions were 8.0 ± 4.4. In patients who were treated with ESWT on the abdomen, the mean number of pulses for F-SWT were 2600.0 ± 2408.3 shocks/session and for R-SWT were 8400.0 ± 894.4 pulses/session, and the number of treatment sessions were 3.2 ± 1.6. Most patients were satisfied with the results. Pain during ESWT was well tolerated and post-ESWT edema was more common in R-SWT than in F-SWT. CONCLUSION: Our data demonstrated that ESWT effectively and safely improved the clinical appearance and functional movement of patients with dermal and subdermal fibrosis caused due to various reasons.

The characteristics and mechanism of NaHCO3 compound fly ash in suppressing gas explosions in pipeline networks.

Gas has been widely concerned due to its importance in the industrial and energy fields. In order to improve the inhibition effect of gas explosion, under the self-constructed pipe network system, the inhibition of gas explosion by composite inhibitor of fly ash and NaHCO3 with different ratios was investigated, and the microscopic inhibition mechanism of the two kinds of powders on the explosion of gas was investigated based on the method of density functional theory and transition state theory from the perspective of molecular dynamics. The results show that: the composite powder explosion suppression is better than a single powder, explosion suppression effect with the increase in the proportion of the mass of NaHCO3 significantly improve the 5 groups of conditions NaHCO3 loading of 40% (by mass) is the best, this time, the explosion of the peak overpressure, the peak flame propagation velocity, the peak flame temperature compared to the maximum reduction in the percentage of the measures taken for the maximum of 74.42%, 81.93%, 68.71%. In addition, NaHCO3, fly ash effectively inhibit the key primitive reaction of gas explosion. When the temperature reaches a certain point, the two and O*, O2, OH* and H* reaction rate higher than the rate of CH4 oxidation chain reaction, the dominant reaction, the maximum difference in rate constants of 70.95, 58.81, 60.06, 44.94. The study of the transition from the macro-scale to the molecular level of the study, in-depth understanding of the mechanism of explosion suppression, to reduce the risk of explosion from the ground up, and enriches the Gas explosion prevention and control of the theoretical system, for the operators to provide a strong technical guarantee for safe production.

The Use of Extracorporeal Shock Wave Lithotripsy to Manage a Knotted Ureteric Stent: A Case Report.

This case report describes the successful management of a knotted ureteric stent in a 57-year-old male with diabetes mellitus, who presented with left flank pain and lower urinary tract symptoms after seven months of stent placement. Initial imaging revealed migration and encrustation of the stent, along with knotting at the proximal end. As rigid cystoscopy to attempt stent retrieval met resistance, a semirigid ureteroscope was used to laser transect the stent, allowing for the insertion of a new stent. Following this, extracorporeal shock wave lithotripsy was performed to target the knotted portion, successfully facilitating its unknotted migration. Final imaging confirmed the appropriate positioning of both stents, enabling their subsequent removal without complications. This case underscores an effective, innovative approach to managing complex ureteric stent complications.

The Role of Extracorporeal Shock Wave Therapy in Keloids and Hypertrophic Scars: A Systematic Review.

Keloids and hypertrophic scars are pathological scars that result from a prolonged and aberrant response to wound healing, resulting in raised and thickened skin lesions. Traditional treatments include occlusive dressings, compression therapy, intralesional steroids, and surgical excision with refashioning. Extracorporeal shock wave therapy (ESWT) is a non-invasive treatment method that employs mechanotransduction to stimulate a biological cascade resulting in tissue regeneration. This review aims to explore the literature for published evidence on the role of ESWT in the treatment of keloids and hypertrophic scars. A literature search following the PRISMA guidelines was conducted on PUBMED, Google Scholar, and the Cochrane Database of Systematic Reviews, for studies demonstrating the use of ESWT in keloids and hypertrophic scars. From this, 79 articles were identified, 12 of which met the eligibility criteria and were thus analyzed and included in the study. As monotherapy for keloids, ESWT showed comparable improvements in functional and aesthetic outcomes compared to traditional intralesional steroid therapy. Keloids treated with combination therapy of ESWT with intralesional steroids had better outcomes than those treated with intralesional steroids alone. Improvements in hypertrophic scar cosmesis, discomfort, and function with the use of ESWT were reported. Histologic improvements such as decreased collagen content, reduction of fibrotic markers, and fibrogenic cytokines were also described. ESWT is a promising treatment modality for pathological scars, offering comparable outcomes to traditional therapies with added benefits such as non-invasiveness. Further research is warranted to establish optimal protocols and its role in pathological scar management.

Combination of melatonin-delivered endothelial progenitor cells with S-nitroso-N-acetyl-DL-penicillamine for improving critical limb ischemia in the rat.

BACKGROUND: This study tested whether combined shock wave (SW)-facilitated melatonin (Mel) delivered into endothelial progenitor cells (EPCs) (EPCSW-Mel) plus S-nitroso-N-acetyl-DL-penicillamine (SNAP) was superior to merely one modality alone for improving critical limb ischemia (CLI) in rats. METHODS: SD rats (n = 50) were equally categorized into group 1 (sham-control), group 2 (CLI), group 3 (CLI + SNAP), group 4 (CLI + EPCSW-Mel), and group 5 (CLI + EPCSW-Mel + SNAP), and ischemia-involved quadriceps were harvested by day 14. RESULTS: An in vitro study showed that at time points of 24/48/72 h, the cell viability/protein expression of endothelial nitric oxide synthase (eNOS)/and cellular expression of nitric oxide (NO) were highest in EPCs, lowest in EPCs + menadione, and much higher in EPCSW-Mel + Mena than in EPCs + Mena + Mel. Protein levels of oxidative-stress (NOX-1/NOX-2/oxidized protein)/early (AN-V+/PI-)/late (AN-V+/PI+) apoptosis and total intracellular/mitochondrial reactive oxygen species ROS exhibited an antithetical trend of cell viability among the groups (all P<0.0001). Matrigel assay of angiogenesis/positively-stained NO cells showed that they were much higher in EPCs + SNAP than in EPCs only (all P<0.0001). Ex vivo angiogenesis/arterial relaxation of carotid-artery rings were highest in left-common-carotid-artery (LCCA) + SNAP, lowest in LCCA + Mena, and notably higher in LCCA than in LCCA + Mena + SNAP (all P<0.0001). Laser Doppler showed ischemic to normal-blood-flow (INBF) ratio was highest in group 1, lowest in group 2, and it progressively increased from groups 3 to 5 (all P<0.0001). The protein levels of oxidative-stress (NOX-1/NOX-4/oxidized protein)/apoptotic [cleaved-caspase-3/cleaved apoptosis/mitochondrial-damage (cytosolic-cytochrome-C/p-DRP-1)]/fibrotic (Smad3/TGF-ß)/inflammatory (MMP-9/IL-1ß/TNF-α/NF-κB) biomarkers, exhibited an opposite trend, whereas the protein level of endothelial-cell surface markers (CD31/vWF/eNOS) and number of small vessels exhibited an identical pattern of INBF ratio among the groups (all P<0.0001). CONCLUSIONS: Combined EPCSW-Mel and SNAP therapy offered a synergic effect toward rescuing from CLI.

Effects of dexamethasone on the EC50 of remifentanil combined with dexmedetomidine achieving analgesia during pancreatic extracorporeal shockwave lithotripsy: a prospective, randomized and controlled study.

BACKGROUND: In addition to their classic genomic effects, glucocorticoids also manifest rapid non genomic effects. We speculate that dexamethasone has the potential prompt onset of analgesic effects. The objective of this study is to investigate the influence of a single preoperative dose of dexamethasone on the half maximal effective concentration (EC50) of remifentanil when combined with dexmedetomidine for pain relief during pancreatic extracorporeal shockwave lithotripsy (P-ESWL). METHODS: A total of 60 patients undergoing P-ESWL were enrolled and randomized at 1:1 ratio into the dexamethasone (DXM) group and the placebo group. Before anesthesia induction, patients in DXM group received an intravenous injection of 8 mg dexamethasone, while subjects in placebo group received an equal dose of physiological saline. Monitored anesthesia care (MAC) was performed based on remifentanil in combination with dexmedetomidine. Remifentanil was administered by TCI with an initial target concentration of 2.5 µg/mL for both groups. A positive response was defined as that VAS score > 3 by the patient at any time during the procedure. Subsequent target concentrations were adjusted by Dixon up-down sequential method, where dose modifications were performed by 0.3 ng/mL intervals, based on the response of the previous patient. The EC50 of remifentanil for pain relief during P-ESWL treatment was calculated using Dixon's up-and-down method. Hemodynamic variables, oxygen saturation and adverse events were also recorded. RESULTS: Dixon up-and-down method revealed that the EC50 of remifentanil was significantly higher in placebo group (2.65 ± 0.28 ng/mL) than in DXM group (2.02 ± 0.23 ng/ml) (P < 0.001). Hemodynamic parameter exhibited a significant decrease in mean arterial pressure (MAP) and heart rate (HR) before and after induction in placebo group; however, data of the two groups were comparable (P>0.05). Less adverse events occurred in DXM group, including the incidence of postoperative nausea and vomiting (PONV) and analgesia requirement with in the first 24 h following the procedure at ward. CONCLUSION: Dexamethasone exerted analgesic effects with a rapid onset, and patients received dexamethasone 8 mg preoperative had a lower required EC50 of remifentanil during P-ESWL. It is also associated with reduced PONV in addition to reduced postoperative analgesic consumption in the first postoperative 24 h.

Walter Brendel and the dawn of transplantation research in Germany.

Walter Brendel was a physiologist who headed the Institut of Experimental Surgery at the University of Munich (LMU) from 1961 until 1989. His legendary career began with the development of an anti-human lymphocyte globulin (ALG) at his Institute during the late 1960s. The initial successful treatment of a small number of patients culminated in the co-treatment of the first successfully heart-transplanted patient in Capetown, South Africa (successful reversal with ALG of an acute allograft rejection). Walter Brendel was a pioneering personality whose work has laid a wide platform for the promotion of interdisciplinarily conducted innovative research programs in various domains of translational science and medicine. Among the many innovative achievements, the most notable are: discovery of involvement of the alternative pathway of complement activation in hyperacute xenograft rejection; induction of immunological tolerance to horse IgG as a means to prevent anaphylactic reactions during ALG therapy; development and clinical implementation of the extracorporeal shock wave lithotripsy for extracorporeal destruction of renal and ureteral calculi. The legacy of Brendel continues with the foundation of the Walter-Brendel Kolleg für Transplantationsmedizin (i.e., the German Transplant School for Transplantation Medicine), which has been held annually since 1994.

Modelling of enhanced gas extraction in low permeability coal seam by controllable shock wave fracturing.

The controlled shock wave (CSW) fracturing is an effective method for enhancing permeability of coal seam to promote gas extraction. Based on Fick's law, Darcy's law, the ideal gas law and the Langmuir equation, a damage-seepage-deformation coupling mathematical model of CSW fracturing in coal seam combined with the maximum tensile stress and the Mohr-Coulomb criterion is established. This model is implemented into COMSOL Multiphysics to simulate the coal seam CSW fracturing and subsequent gas extraction. When the shock wave and isotropic in-situ stress are applied on the borehole wall, the coal damage zone is an annular shape, and the permeability in the damage zone increases sharply. The CSW can effectively increase the efficiency of gas extraction and reduce the gas pressure and gas content in coal seam. With the increase of CSW action times, the damage in coal mass reaches a threshold and tends to be stable after several shocks. The damage area and the gas extraction efficiency are positively correlated with the shock intensity. Under the anisotropic ground stress, the larger diversity of the stress in different directions is, the more obvious damage extension in the fractured coal along the maximum stress direction is. Ground stress can inhibit the extension of cracks in the CSW fractured coal seam. This inhibition effect becomes more obvious with the increase of in-situ stress. Parameters are substantiated of controlled shock wave impact on the coal seam, which ensures increased methane extraction from low-permeability reservoirs, are substantiated.

Cellular regenerative therapy in stress urinary incontinence: new frontiers?-a narrative review.

Background and Objective: Even if treatment with stem cells has been shown to be safe and effective in many patients with stress urinary incontinence (SUI), there is still room for improvement using other regenerative medicine alternatives. Since the beneficial effects of stem cells are probably mediated by secretion of factors rather than by the cells themselves there is a good rationale for further exploring the therapeutic effects of the secretome and/or its components. However, homing factors such as stromal derived growth factor 1 (SDF-1; CXCL12), stimulation of stem cell growth and stem cell mobilization in vivo using low intensity shock wave therapy (Li-ESWT) or regenerative electrical stimulation (RES), are also promising approaches. Methods: A literature search was performed based on PubMed, Scopus and Google Scholar. The search criteria included original basic science articles, systematic reviews and randomized control trials. All studies were published between 2000 and 2023. Selected, peer-reviewed studies were further analyzed to identify those of relevance. Keywords searched included: "female stress incontinence", "homing factors", "CXCL12", "secretome", "low intensity shockwave therapy" and "regenerative electrical stimulation". The peer-reviewed publications on the key word subjects that contained a novel addition to the existing body of literature were included. Key Content and Findings: There is evidence from studies on non-human primates (NHPs) with experimental urinary sphincter injury that CXCL12 can restore sphincter structure and function. Studies with homing factors in human patients with SUI are still to be performed. A large number of clinical studies on the use of secretome or secretome products from mesenchymal stem cells (MSCs) on indications other than human SUI are already available. However, controlled clinical trials on patients with SUI, have to the best of our knowledge, not yet been performed. Also, RES has not been studied in patients with SUI. In contrast, there is clinical evidence that Li-ESWT may improve female SUI. Conclusions: Treatment with homing factors, MSC secretome/secretome components, Li-ESWT and RES are promising frontiers in the treatment of human SUI caused by sphincter damage.

Focused shock waves and inertial cavitation release tumor-associated antigens from renal cell carcinoma.

Tumor biomarkers play an essential role in immunotherapeutic strategies in cancer treatment, contributing to early diagnosis, patient selection, treatment monitoring, and personalized treatment plans. Despite their importance in cancer care, circulating biomarkers may not always be detectable or sufficiently elevated to provide reliable test results. Due to the pressing need for innovative approaches to enhance biomarker levels, this study explored the potential use of focused shock waves and cavitation for non-invasively releasing tumor-associated antigens. Renal carcinoma cell lines ACHN and TOS-1 were used in an in vitro study to analyze the impact of shock waves on two membrane glycosphingolipid antigens, MSGG and G1, respectively. Focused shock waves were generated using a partial spherical piezoceramic dish. Flow-cytometric analysis of treated cells immediately after 1,000 focused shock waves at 16 MPa overpressure showed a 29.4 % and 17.6 % decrease in MSGG and G1 antigens on the cell surfaces. In the immunostaining of glycosphingolipid fractions on thin-layer chromatography (TLC), both tumor markers were reduced by an average of 49.30 % (MSGG) and 57.08 % (G1). Immunoelectron microscopy images confirmed decrease in the cell membrane intensity immediately after shock waves because of the release of antigens into the extracellular spaces. The released antigens were primarily found on cell debris formed by shock waves and cavitation induced damage to the cell membrane. Theoretical analyses were performed to understand antigen release mechanisms. Moreover, the biophysical events that occurred following the interaction of a shock wave with a suspended cell were modeled and clarified. A novel model was used to calculate the tensile stresses following shock waves and to explain the deformations observed in scanning electron microscopy images. The release of tumor antigens by focused shock waves and inertial cavitation represents exciting prospects for advancing cancer care strategies.

Effects of Particle Migration on the Relaxation of Shock Wave Collisions.

The non-equilibrium characteristics during the shock relaxation process hold a foundational position in various fields. In contrast to the propagation of a single shock wave, the collision process of two shock waves exhibits distinct non-equilibrium features. Employing non-equilibrium molecular dynamics, we simulated the collision of ultra-strong shock waves in a classical gas system, investigating the relationship between equilibrium relaxation time and shock intensity. Tracking the spatial migration of microscopic particles in the shock collision region during the relaxation process, we observed a significant contribution of particle migration to the average energy changes during relaxation. The discussion on particle migration provides a valuable new perspective for understanding the microscopic mechanisms of the relaxation process.

Safety evaluation of extracorporeal shockwave lithotripsy for pancreatic stones: Experience based on a large chronic pancreatitis cohort.

BACKGROUND: The safety of extracorporeal shock wave lithotripsy for pancreatic stones (P-ESWL) and adverse events were not evaluated and classified within large sample population. This study aimed to evaluate the safety and classify the adverse events of P-ESWL based on a large sample cohort. METHODS: This is an observational study based on the large prospective chronic pancreatitis (CP) cohort. Patients with painful pancreatic stones over 5 mm who underwent P-ESWL between March 2011 and June 2018 at Shanghai Changhai Hospital were included. Adverse events after P-ESWL including complications and transient adverse events (TAEs) were recorded. Risk factors of adverse events were analyzed through univariable and multivariable logistics regression analysis. Sensitivity analysis was conducted to test the stability of the study. RESULTS: Totally 2,071 patients underwent 5,002 sessions of P-ESWL were included. The overall complication rate and TAEs rate after all P-ESWL procedures were 5.2% and 20.9%. The complications and TAEs rate decreased obviously within the first 6 sessions. Several independent risk factors for adverse events after P-ESWL were identified. Sensitivity analysis suggested the stability of the results. CONCLUSIONS: P-ESWL is a safe treatment for pancreatic stones. Multiple P-ESWL sessions did not increase the complications and TAEs rate.

Effect of Extracorporeal Shock Wave on IGF-1, TNF-α, and IL-1in Joint Fluid of Patients with Temporomandibular Joint Disorder Syndrome.

As a new therapeutic method, extracorporeal shock wave (ESW) has shown remarkable efficacy in the treatment of temporomandibular joint disorder syndrome. Numerous studies have shown that it has the advantages of noninvasiveness, short treatment time, etc. It can effectively relieve pain and improve symptoms such as joint mobility and opening degree. In clinical practice, through accurate diagnosis and positioning of different patients, appropriate treatment parameters such as therapeutic transducer, frequency and pressure can be selected to significantly improve the efficacy. At the same time, follow-up evaluation after treatment, including temporomandibular joint disorder index and visual analogue score, is also helpful to fully understand the rehabilitation of patients. Extracorporeal shock wave therapy (ESWT) brings new hope to patients with temporomandibular joint disorder syndrome and has a broad application prospect.

Effectiveness of various interventions for non-traumatic osteonecrosis: a pairwise and network meta-analysis.

Background: Osteonecrosis of the femoral head (ONFH) is acknowledged as a prevalent, challenging orthopedic condition for patients. Purpose: This study aimed to evaluate the efficacy of various interventions for non-traumatic ONFH and provide guidance for clinical decision-makers. Methods: We searched PubMed, Embase, Cochrane Library, and Web of Science databases from inception to February 2023 for relevant randomized controlled trials evaluating treatments for femoral head necrosis, without language restrictions. Quality evaluation was performed using the Cochrane risk-of-bias assessment tool, and analysis was performed using Stata 15.1. Results: Eleven randomized controlled trials were included in this study. The meta-analysis results revealed that CellTherapy [MD= -3.46, 95%CI= (-5.06, -1.85)], InjectableMed [MD= -3.68, 95%CI= (-6.11, -1.21)], ESWT [MD= -2.84, 95%CI= (-4.23, -1.45)], ESWT+InjectableMed [MD= -3.86, 95%CI= (-6.22, -1.53)] were significantly more effective in improving VAS pain score than CD+PTRI, as well as CD+BG+CellTherapy, and CD+BG. Furthermore, CD+BG+CellTherapy was better than CD+BG [MD= -0.97, 95%CI= (-1.71, -0.19)]. The SUCRA ranking for HHS score indicated that CellTherapy (77%) has the best effectiveness rate, followed by ESWT+InjectableMed (72.2%), ESWT (58.3%), InjectableMed (50%), CD+PTRI (31.4%), and CD+BG (11%). In terms of WOMAC and Lequesne scores, the meta-analysis showed no statistically significant differences between the experimental group CD+BG+CellTherapy and the control group CD+BG. Conclusion: CellTherapy and non-surgical ESWT combined with medication or CellTherapy have the best effect on ONFH. Surgical CD+BG combined with CellTherapy is more effective than CD+BG alone. ESWT+InjectableMed is recommended for short-term or acute onset patients, while ESWT is recommended for long-term patients.

Electroacupuncture combined with extracorporeal shock wave lithotripsy is beneficial for the expulsion of ureteral calculi: a prospective randomized trial.

PURPOSE: To evaluate the therapeutic efficacy and safety of electroacupuncture (EA) combined with extracorporeal shock wave lithotripsy (ESWL) in treating ureteral calculi. METHODS: This prospective randomized controlled trial included 207 patients with ureteral calculi who were randomly allocated to an experimental group that underwent EA plus ESWL (n = 95) and a control group that underwent only ESWL (n = 112). Imaging examinations were performed at 1, 2, and 4 weeks after the operation, followed by comparing the stone-clearance rate, time to first stone expulsion, and incidence of major complications between the two groups. RESULTS: The stone-clearance rates at 1 (59.1 vs. 37%, P = 0.002), 2 (86.4 vs. 59.3%, P = 0.000), and 4 (90.9 vs. 77.8%, P = 0.013) weeks after the operation in the experimental group were significantly higher than those in the control group. The time to first stone expulsion in the experimental group was significantly lower than that in the control group (1.29 ± 1.55 vs. 2.45 ± 3.11 days, respectively; P = 0.001). However, we found no difference in the incidence of major complications between the two groups (15.9 vs. 17.6%, P = 0.754). CONCLUSION: EA-assisted ESWL significantly improved stone clearance and shortened the time to stone expulsion without elevating the complication risk. However, a large-scale multicenter, prospective study is required to corroborate our conclusions.

Extracorporeal Shock Wave Therapy (eSWT) in Spinal Cord Injury-A Narrative Review.

BACKGROUND: Injury of the spinal cord causes motor and sensory dysfunction as well as pathological reflexes, leading to paraplegia or tetraplegia. The sequelae of traumatic spinal cord injury (SCI) are a significant burden and impact on healthcare systems. Despite constant progress in medicine, traumatic SCI still remains irreversible. To date, no satisfying treatment that can enable neuronal regeneration and recovery of function at the damaged level has been found. Hundreds of experiments have been conducted on various possibilities of influencing spinal regeneration; some of them have yielded promising results, but unfortunately, the successes obtained in experimental animals have not translated into humans. METHODS: This narrative review article presents the application of extracorporeal shock wave therapy (eSWT) in patients with SCI. The article has been divided into parts: 1) use of extracorporeal shock wave therapy for regeneration of the spinal cord after traumatic spinal cord injury; 2) application of extracorporeal shock wave therapy in spasticity after spinal cord injury. In both cases, the hypotheses of possible mechanisms of action will be described. RESULTS AND CONCLUSIONS: A small number of clinical trials have demonstrated the potential of eSWT to influence the regeneration of the spine, as an innovative, safe, and cost-effective treatment option for patients with SCI. Some reports have shown that eSWT can improve spasticity, walking ability, urological function, quality of life, and independence in daily life.

Effects of radial extracorporeal shock wave with different frequencies on acute skeletal muscle injury in rabbits.

To study the efficacy and possible mechanisms of radial extracorporeal shock wave (rESW) with different frequencies for the treatment of acute skeletal muscle injury in rabbits, 48 rabbits of acute injured biceps femoris were randomly divided into 4 groups. Except for the control group, the other groups were treated by rESW with 5 Hz, 10 Hz and 15 Hz, respectively. The injury symptom index scores (ISISs) in the rESW group were significantly lower than those in the control group, with the lowest in the 10 Hz rESW group. Histomorphological features demonstrated a decrease in mononuclear cells and an increase in new myocytes across all groups, with the rESW group showing the most significant changes. The concentrations of PGE2 and IL-1ß were significantly lower in all rESW groups by ELISA compared to the control group. Additionally, the 10 Hz group had lower concentrations than the 5 Hz and 15 Hz group. Compared with the control group, MyoD of the rESW groups was significantly increased, and the expression level of the 10 Hz group was higher than that of the other groups. In conclusion, rESW with 5 Hz, 10 Hz and 15 Hz take certain curative effects on acute biceps femoris injury in rabbits, and the 10 Hz rESW takes advantage over 5 Hz and 15 Hz rESW.
