Yan X, Ye Y, Wang L, Xue J, Shen N, Li T. Platelet-rich plasma alleviates neuropathic pain in osteoarthritis by downregulating microglial activation. BMC Musculoskelet Disord 2024; 25:331. [PMID: 38725009 PMCID: PMC11080143 DOI: 10.1186/s12891-024-07437-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Accepted: 04/12/2024] [Indexed: 05/13/2024] Open
Abstract
BACKGROUND The development of neuropathic pain (NP) is one of the reasons why the pain is difficult to treat, and microglial activation plays an important role in NP. Recently, platelet-rich plasma (PRP) has emerged as a novel therapeutic method for knee osteoarthritis (KOA). However, it's unclarified whether PRP has analgesic effects on NP induced by KOA and the underlying mechanisms unknown. PURPOSE To observe the analgesic effects of PRP on NP induced by KOA and explore the potential mechanisms of PRP in alleviating NP. METHODS KOA was induced in male rats with intra-articular injections of monosodium iodoacetate (MIA) on day 0. The rats received PRP or NS (normal saline) treatment at days 15, 17, and 19 after modeling. The Von Frey and Hargreaves tests were applied to assess the pain-related behaviors at different time points. After euthanizing the rats with deep anesthesia at days 28 and 42, the corresponding tissues were taken for subsequent experiments. The expression of activating transcription factor 3 (ATF3) in dorsal root ganglia (DRG) and ionized-calcium-binding adapter molecule-1(Iba-1) in the spinal dorsal horn (SDH) was detected by immunohistochemical staining. In addition, the knee histological assessment was performed by hematoxylin-eosin (HE) staining. RESULTS The results indicated that injection of MIA induced mechanical allodynia and thermal hyperalgesia, which could be reversed by PRP treatment. PRP downregulated the expression of ATF3 within the DRG and Iba-1 within the SDH. Furthermore, an inhibitory effect on cartilage degeneration was observed in the MIA + PRP group only on day 28. CONCLUSION These results indicate that PRP intra-articular injection therapy may be a potential therapeutic agent for relieving NP induced by KOA. This effect could be attributed to downregulation of microglial activation and reduction in nerve injury.

Platelet-rich Plasma Improves Radiotherapy-induced Emotional Disorder and Cognitive Dysfunction, Neuroinflammation in Aged Rats by Inhibiting the Activation of NLRP3 Inflammasomes. Neurochem Res 2023:10.1007/s11064-023-03933-9. [PMID: 37043084 DOI: 10.1007/s11064-023-03933-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Revised: 03/01/2023] [Accepted: 03/31/2023] [Indexed: 04/13/2023]
Abstract
Although radiotherapy (RT) is the preferred treatment for elderly patients with brain tumors, certain negative effects can't be ignored. Fortunately, platelet-rich plasma (PRP) presents with a promising potential for the treatment of neurological diseases. Therefore, this study aimed to explore the effect of PRP on neuroinflammation, emotional disorder and cognitive dysfunction induced by RT in aged rats. Firstly, whole brain RT (WBRT) model was established by whole brain irradiation with 10 Gy of 6-MeV electron beam in rats. Next, twenty 20-month-old female SD rats were divided into four groups (sham group, PRP group, WBRT group, and WBRT + PRP group) according different treatments. After that, the cognitive dysfunction and depression-like behavior of rats were examined by novel object recognition test (NORT), Morris water maze test (MWM), open field test (OFT) and elevated plus maze test (EPM). Besides, immunohistochemistry was used to detect the expression of microglial marker protein Iba-1 in rat hippocampus; enzyme linked immunosorbent assay (ELISA) to examine the levels of pro-inflammatory cytokines tumor necrosis factor-alpha (TNF-α), interleukin (IL)-1 beta (IL-1β), IL-18, and monocyte chemoattractant protein 1 (MCP-1) in rat hippocampus; real-time quantitative reverse transcription PCR (qRT-PCR) and western blot to measure the levels of neurotrophic factors brain-derived neurotrophic factor (BDNF), tropomyosin-related kinase B receptor (TrkB), and nerve growth factor (NGF) in rat hippocampus; and western blot also to observe the protein expression levels of NOD-like receptor protein 3 (NLRP3), caspase-1, apoptosis-associated speck-like protein containing a CARD (ASC), and IL-1β in rat hippocampus. After experiments, some results obtained were shown as follows. PRP could significantly improve learning and memory ability and depression-like behavior, increase the level of neurotrophic factors, inhibit the activation of microglia and decrease the level of pro-inflammatory factors in WBRT rats. In addition, PRP significantly inhibited the activation of NLRP3 inflammasomes. To sum up, PRP can ameliorate neuroinflammation, emotional disorder and cognitive dysfunction induced by RT in aged rats, and the mechanism may be related to its inhibitory effect on NLRP3 inflammasome activation.

Int J Mol Sci 2023; 24:ijms24065379. [PMID: 36982452 PMCID: PMC10049379 DOI: 10.3390/ijms24065379] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Revised: 03/06/2023] [Accepted: 03/09/2023] [Indexed: 03/14/2023] Open
Abstract
Paclitaxel (PAC) results in long-term chemotherapy-induced peripheral neuropathy (CIPN). The coexpression of transient receptor potential vanilloid 1 (TRPV1) and Toll-like receptor 4 (TLR4) in the nervous system plays an essential role in mediating CIPN. In this study, we used a TLR4 agonist (lipopolysaccharide, LPS) and a TLR4 antagonist (TAK-242) in the CIPN rat model to investigate the role of TLR4-MyD88 signaling in the antinociceptive effects of hyper-baric oxygen therapy (HBOT). All rats, except a control group, received PAC to induce CIPN. Aside from the PAC group, four residual groups were treated with either LPS or TAK-242, and two of them received an additional one-week HBOT (PAC/LPS/HBOT and PAC/TAK-242/HBOT group). Mechanical allodynia and thermal hyperalgesia were then assessed. The expressions of TRPV1, TLR4 and its downstream signaling molecule, MyD88, were investigated. The mechanical and thermal tests revealed that HBOT and TAK-242 alleviated behavioral signs of CIPN. Immunofluorescence in the spinal cord dorsal horn and dorsal root ganglion revealed that TLR4 overexpression in PAC- and PAC/LPS-treated rats was significantly downregulated after HBOT and TAK-242. Additionally, Western blots showed a significant reduction in TLR4, TRPV1, MyD88 and NF-κB. Therefore, we suggest that HBOT may alleviate CIPN by modulating the TLR4-MyD88-NF-κB pathway.

Abstract
Chronic pain affects patients' physical and psychological health and quality of life, entailing a tremendous public health challenge. Currently, drugs for chronic pain are usually associated with a large number of side effects and poor efficacy. Chemokines in the neuroimmune interface combine with their receptors to regulate inflammation or mediate neuroinflammation in the peripheral and central nervous system. Targeting chemokines and their receptor-mediated neuroinflammation is an effective means to treat chronic pain. In recent years, growing evidence has shown that the expression of chemokine ligand 2 (CCL2) and its main chemokine receptor 2 (CCR2) is involved in its occurrence, development and maintenance of chronic pain. This paper summarises the relationship between the chemokine system, CCL2/CCR2 axis, and chronic pain, and the CCL2/CCR2 axis changes under different chronic pain conditions. Targeting chemokine CCL2 and its chemokine receptor CCR2 through siRNA, blocking antibodies, or small molecule antagonists may provide new therapeutic possibilities for managing chronic pain.

Abstract
BACKGROUND Postoperative healing after clitoral reconstruction (CR) for female genital mutilation/cutting can be long and painful due to prolonged clitoral re-epithelialization time (up to 3 months). Autologous platelet-rich plasma (A-PRP) might reduce postoperative clitoral epithelialization time and pain. OBJECTIVES The authors assessed postoperative clitoral re-epithelialization time and pain after intraoperative clitoral administration of A-PRP. METHODS Five consecutive women underwent CR (Foldès technique) followed by the administration of A-PRP Regen Lab SA (Le Mont-sur-Lausanne, Switzerland) plasma and glue, injected inside and applied above the re-exposed clitoris, respectively. We recorded surgical complications, postoperative clitoral pain (visual analogue scale), painkiller intake, time to complete re-epithelialization, and the experienced subjective changes in sexual response and perception of their own body image referred by women. RESULTS Sexual distress/dysfunction as well as the desire to be physically and symbolically "repaired" were the reasons behind women's requests for surgery. None of the women suffered from chronic vulvar or non-vulvar pain. All women achieved complete clitoral epithelialization by day 80, 3 women between day 54 and 70, and only 1 woman was still taking 1 g of paracetamol twice a day at 2 months postoperative. She had stopped it before the 3-month control. There were no short- or long-term complications. All women described easier access and stimulation of their clitoris as well as improved sexual arousal, lubrication, and pleasure and claimed to be satisfied with their restored body image. CONCLUSIONS A-PRP could expedite postoperative clitoral epithelialization and reduce postoperative pain after CR after female genital mutilation/cutting. LEVEL OF EVIDENCE: 4

Abstract
Purpose To clarify the mechanisms of intrauterine platelet-rich plasma (PRP) infusion that support embryo implantation in in vitro fertilization treatment. Methods Blood and endometrial samples were collected from four infertile women. Human endometrial stromal cells (HESCs) were cultured and passaged equally into four cell culture dishes in each patient. Two were treated with PRP twice, and the other two were treated with vehicle. Subsequently, two cultures with and without PRP were decidualized with 8-bromoadenosine 3',5'-cyclic AMP and progesterone for 5 days. Results The gene expression in undifferentiated or decidualized HESCs with and without PRP was compared. In the microarray analysis, 381 and 63 differentially expressed genes were detected in undifferentiated and decidualized HESCs, respectively. In the undifferentiated HESCs, PRP was found to promote the gene expression associated with cell growth, tissue regeneration, proinflammatory response, and antibiotic effects. In decidualized HESCs, PRP was found to attenuate the gene expression involved in cell proliferation and inflammation by inhibiting the expression of phosphoinositide 3-kinase signaling. Conclusions Platelet-rich plasma regulates the reprogramming of cell proliferation and inflammation depending on menstrual cycle phases in an appropriate manner, suggesting that PRP has the potential to increase endometrial thickness in the proliferative phase and improve immune tolerance in the secretory phase.

Abstract
BACKGROUND Pilonidal disease can be a debilitating condition which carries a significant physical and economic burden. This systematic review and updated meta-analysis presents the evidence for the use of platelet-rich plasma (PRP) for wound healing following open and minimally-invasive sacrococcygeal pilonidal surgery. METHODS A literature search was performed during December 2021 for studies relating to platelet-rich plasma and pilonidal wound healing following surgery. RESULTS Nine studies remained after applying the exclusion criteria, incorporating a total of 621 (open surgery group) and 309 (minimally-invasive group) patients, respectively. Pooled analysis of the six open surgery group studies demonstrated a significant reduction in wound healing time (mean difference [MD] = - 13.98 days, 95% CI - 18.41 to - 9.55, p < 0.001, I2 = 98%). Three open surgery group studies compared post-operative time off work, while three recorded mean pain duration; pooled analysis also revealed a significant reduction in both outcomes, respectively (MD = - 8.7 days, 95% CI - 9.4 to - 8.0, p < 0.001, I2 = 57%; MD = - 9.5 days, 95% CI - 15.6 to - 3.3, p = 0.002, I2 = 98%). Methodological heterogeneity among the minimally-invasive studies precluded formal meta-analysis; however, two studies demonstrated a modest improvement in wound healing when treated with PRP. CONCLUSIONS This systematic review and updated meta-analysis provide further evidence supporting the use of PRP for wound healing in sacrococcygeal pilonidal disease. PRP application was demonstrated to significantly reduce healing time, postoperative pain and time off work in the open surgery group. Nevertheless, there is still considerable heterogeneity among PRP manufacture and administration techniques, and further high-powered RCTs with consistent methodology are required to substantiate these findings.

Abstract
Although modern medicine has made great strides in the management of burn injuries, associated complications such as pain, infection, dyspigmentation, and scarring have yet to be fully dealt with. Although skin grafting and meshing are routinely performed on burn patients, this method poses a risk for adverse effects. Activated autologous platelet-rich plasma (aaPRP), which is increasingly used in the field of plastic surgery, contains growth factors beneficial for wound regeneration. Seven cases of burns with varying severity and conditions that were treated with intralesional subcutaneous injection and intravenous aaPRP are presented and discussed herein. This case series indicates that subcutaneous and intravenous aaPRP is a safe procedure with the potential to be an alternative when skin grafting cannot be done or as an adjunct treatment to skin grafting.

Abstract
The present study attempted to elucidate whether intravesical instillation of platelet-rich plasma (PRP) could decrease bladder inflammation and ameliorate bladder hyperactivity in ketamine ulcerative cystitis (KIC) rat model. Female Sprague Dawley (S-D) rats were randomly divided into control group, ketamine-treated group, ketamine with PRP treated group, and ketamine with platelet-poor plasma (PPP) treated group. Cystometry and micturition frequency/volume studies were performed to investigate bladder function. The morphological change of bladder was investigated by Mason’s trichrome staining. Western blotting analysis were carried out to examine the protein expressions of inflammation, urothelial differentiation, proliferation, urothelial barrier function, angiogenesis and neurogenesis related proteins. The results revealed that treatment with ketamine significantly deteriorated bladder capacity, decreased voiding function and enhanced bladder overactivity. These pathological damage and interstitial fibrosis may via NF-κB/COX-2 signaling pathways and muscarinic receptor overexpression. PRP treatment decreased inflammatory fibrotic biosynthesis, attenuated oxidative stress, promoted urothelial cell regeneration, and enhanced angiogenesis and neurogenesis, thereafter recovered bladder dysfunction and ameliorate the bladder hyperactivity in KIC rat model. These findings suggested that the PRP therapy may offer new treatment options for those clinical KIC patients.

Urinary Biomarkers in Interstitial Cystitis/Bladder Pain Syndrome and Its Impact on Therapeutic Outcome. Diagnostics (Basel) 2021; 12:diagnostics12010075. [PMID: 35054241 PMCID: PMC8774507 DOI: 10.3390/diagnostics12010075] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Revised: 12/18/2021] [Accepted: 12/20/2021] [Indexed: 12/25/2022] Open
Abstract
Interstitial cystitis/bladder pain syndrome (IC/BPS) is defined as a chronic bladder disorder with suprapubic pain (pelvic pain) and pressure and/or discomfort related to bladder filling accompanied by lower urinary tract symptoms, such as urinary frequency and urgency without urinary tract infection (UTI) lasting for at least 6 weeks. IC/BPS presents significant bladder pain and frequency urgency symptoms with unknown etiology, and it is without a widely accepted standard in diagnosis. Patients’ pathological features through cystoscopy and histologic features of bladder biopsy determine the presence or absence of Hunner lesions. IC/PBS is categorized into Hunner (ulcerative) type IC/BPS (HIC/BPS) or non-Hunner (nonulcerative) type IC/BPS (NHIC/BPS). The pathophysiology of IC/BPS is composed of multiple possible factors, such as chronic inflammation, autoimmune disorders, neurogenic hyperactivity, urothelial defects, abnormal angiogenesis, oxidative stress, and exogenous urine substances, which play a crucial role in the pathophysiology of IC/BPS. Abnormal expressions of several urine and serum specimens, including growth factor, methylhistamine, glycoprotein, chemokine and cytokines, might be useful as biomarkers for IC/BPS diagnosis. Further studies to identify the key molecules in IC/BPS will help to improve the efficacy of treatment and identify biomarkers of the disease. In this review, we discuss the potential medical therapy and assessment of therapeutic outcome with urinary biomarkers for IC/BPS.

Abstract
BACKGROUND AND OBJECTIVE Neuropathic pain arises as a direct consequence of a lesion or disease affecting the somatosensory system. A number of preclinical studies have provided evidence for the involvement of cytokines, predominantly secreted by a variety of immune cells and by glial cells from the nervous system, in neuropathic pain conditions. Clinical trials and the use of anti-cytokine drugs in different neuropathic aetiologies support the relevance of cytokines as treatment targets. However, the use of such drugs, in particularly biotherapies, can provoke notable adverse effects. Moreover, it is challenging to select one given cytokine as a target, among the various neuropathic pain conditions. It could thus be of interest to target other proteins, such as growth factors, in order to act more widely on the neuroinflammation network. Thus, platelet-rich plasma (PRP), an autologous blood concentrate, is known to contain a natural concentration of growth factors and immune system messengers and is widely used in the clinical setting for tissue regeneration and repair. DATABASE AND DATA TREATMENT In the present review, we critically assess the current knowledge on cytokines in neuropathic pain by taking into consideration both human studies and animal models. RESULTS This analysis of the literature highlights the pathophysiological importance of cytokines. We particularly highlight the concept of time- and tissue-dependent cytokine activation during neuropathic pain conditions. RESULTS Conclusion: Thus, direct or indirect cytokines modulation with biotherapies or growth factors appears relevant. In addition, we discuss the therapeutic potential of localized injection of PRP as neuropathic pain treatment by pointing out the possible link between cytokines and the action of PRP. SIGNIFICANCE Preclinical and clinical studies highlight the idea of a cytokine imbalance in the development and maintenance of neuropathic pain. Clinical trials with anticytokine drugs are encouraging but are limited by a 'cytokine candidate approach' and adverse effect of biotherapies. PRP, containing various growth factors, is a new therapeutic used in regenerative medicine. Growth factors can be also considered as modulators of cytokine balance. Here, we emphasize a potential therapeutic effect of PRP on cytokine imbalance in neuropathic pain. We also underline the clinical interest of the use of PRP, not only for its therapeutic effect but also for its safety of use.

Abstract
Our study aims to elucidate the role of platelet-rich plasma (PRP) in rats chondrocytes inflammation and mechanism. PRP was obtained from 8 weeks old rats. Then, the knee joint of bilateral hind limbs was dissected and articular chondrocytes were obtained in super-clean table after
dislocation and identified at the second generation during culture and passage. Chondrocytes were divided into control group 1 (addition of saline), control group 2 (IWP-2, Wnt/β-catenin axis inhibitor) and experimental group (PRP) followed by analysis of mRNA levels of glycogen
synthase kinase-3 (GSK-3β), low-density lipoprotein receptor-associated protein 5 (LRP5), Wnt1 and β-catenin by RT-PCR, IL-1 and TNF-α after 1 week by ELISA. The second generation articular chondrocytes presented polygonal or triangular cell morphology,
positive for collagen II and toluidine blue staining. PRP addition significantly reduced GSK-3β and LRP5 mRNA level, and increased β-catenin and Wnt1 mRNA levels in chondrocytes. Meanwhile, it suppressed IL-1 and TNF-α secretion and Wnt protein production
inhibitor 2. PRP might suppresses inflammatory factors production of rat articular chondrocytes through inhibiting Wnt/β-catenin axis.

Abstract
Split thickness skin grafting is a common reconstructive technique which carries unavoidable donor site morbidity. The aim of this systematic review and meta-analysis is to present the evidence for the use of platelet rich plasma as an adjunct to donor site wound healing. A comprehensive literature search was performed, according to PRISMA guidelines from inception to August 2020, for studies regarding platelet rich plasma and skin graft donor site healing. Animal studies, case series of less than three cases and studies reporting histological outcomes only were excluded. The literature search identified 114 articles. After applying the exclusion criteria, four randomised control trials and two case-control studies remained, incorporating a total of 218 wounds in 139 patients. Four out of six studies reported total healing times for donor site wounds. Pooled analysis showed a significant reduction in healing time when donor wounds were treated with PRP versus controls [MD 5.95, 95% CI 5.04-6.85, p < 0.001]. Of the five studies which reported pain at dressing change, four showed significantly reduced pain scores for the platelet rich plasma treated wounds versus control. There were no significant complications recorded in the treated wounds. The current evidence basis for platelet rich plasma in donor site healing is limited by heterogeneous methodology and reporting outcomes and low powered studies. Nevertheless, the preponderance of data supports its use for accelerating wound healing and reducing pain at dressing change. These preliminary findings need to be substantiated with higher powered randomised controlled trials with standardised PRP manufacture and reporting structures.

Abstract
Severe burns are acute wounds caused by local heat exposure, resulting in life-threatening systemic effects and poor survival. However, the specific molecular mechanisms remain unclear. First, we downloaded gene expression data related to severe burns from the GEO database (GSE19743, GSE37069, and GSE77791). Then, a gene expression analysis was performed to identify differentially expressed genes (DEGs) and construct protein-protein interaction (PPI) network. The molecular mechanism was identified by enrichment analysis and Gene Set Enrichment Analysis. In addition, STEM software was used to screen for genes persistently expressed during response to severe burns, and receiver operating characteristic (ROC) curve was used to identify key DEGs. A total of 2631 upregulated and 3451 downregulated DEGs were identified. PPI network analysis clustered these DEGs into 13 modules. Importantly, module genes mostly related with immune responses and metabolism. In addition, we identified genes persistently altered during the response to severe burns corresponding to survival and death status. Among the genes with high area under the ROC curve in the PPI network gene, CCL5 and LCK were identified as key DEGs, which may affect the prognosis of burn patients. Gene set variation analysis showed that the immune response was inhibited and several types of immune cells were decreased, while the metabolic response was enhanced. The results showed that persistent gene expression changes occur in response to severe burns, which may underlie chronic alterations in physiological pathways. Identifying the key altered genes may reveal potential therapeutic targets for mitigating the effects of severe burns.

Simultaneous hyperbaric oxygen therapy during systemic chemotherapy reverses chemotherapy-induced peripheral neuropathy by inhibiting TLR4 and TRPV1 activation in the central and peripheral nervous system. Support Care Cancer 2021; 29:6841-6850. [PMID: 34003380 DOI: 10.1007/s00520-021-06269-8] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2020] [Accepted: 05/04/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND AND OBJECTIVES Chemotherapy-induced peripheral neuropathy (CIPN) is considered one of the most common sequelae in patients with cancer who experience consistent abnormal sensations or pain symptoms during or after paclitaxel (PAC) chemotherapy. Transient receptor potential vanilloid 1 (TRPV1) and toll-like receptor 4 (TLR4) have been reported to interact in the nervous system in patients with CIPN. The antinociceptive effects of hyperbaric oxygen therapy (HBOT) on CIPN was demonstrated in this study through behavior tests. Using a CIPN rat model, we examined the effects of simultaneous HBOT (SHBOT) administration during chemotherapy and discovered that SHBOT achieved better reversal effects than chemotherapy alone. MATERIALS AND METHODS Twenty-four rats were randomly allocated to four groups: control, PAC, SHBOT, and HBOT after PAC groups. Behavior tests were performed to evaluate mechanical allodynia and thermal hyperalgesia status. Tissues from the spinal cord and dorsal root ganglions were collected, and TLR4 and TRPV1 expression and microglial activation were investigated through immunofluorescence (IF) staining. RESULTS The mechanical and thermal behavior tests revealed that HBOT intervention during PAC treatment led to the early alleviation of CIPN symptoms and inhibited CIPN deterioration. IF staining revealed that TLR4, TRPV1, and microglial activation were all upregulated in PAC-injected rats and exhibited early and significant downregulation in SHBOT-treated rats. CONCLUSION This study is the first to demonstrate that the use of SHBOT during PAC treatment has potential for the early suppression of CIPN initiation and deterioration, indicating that it can alleviate CIPN symptoms and may reverse CIPN in patients undergoing systemic chemotherapy.

Abstract
INTRODUCTION Female genital mutilation (FGM) includes all procedures that involve partial or total removal of the female external genitalia or any other injury of the female genitalia that is performed for nonmedical reasons. FGM is classified into 4 types. Surgical clitoral reconstruction was first described by Thabet and Thabet in Egypt and subsequently by Foldès in France. The technique was then modified by different authors. AIM This article aims to provide a detailed description of clitoral surgical reconstruction and the modifications which have been made over time to improve the procedure while recalling current knowledge in the anatomy of the clitoris. METHODS We performed a broad systematic search in PubMed/Medline and EMBASE bibliographic databases for studies that report the surgical technique of clitoral reconstruction. From the anatomical point of view, we examined available evidence (from 1950 until 2020) related to clitoral anatomy, the clitoral role in sexual functioning, female genital mutilation/cutting, and surgical implications for the clitoris. MAIN OUTCOMES A review of the surgical techniques for clitoral reconstruction after female genital mutilation/cutting RESULTS: We described the current anatomical knowledge about the clitoris, and the procedures based on the surgical technique by Pierre Foldès, We included the technical modifications and contributions described in articles published subsequently. CONCLUSION Surgical repair of the clitoris for FGM offers anatomical and functional results although they still have to be evaluated. However, it should not be the only therapeutic solution offered to women with FGM. Botter C, Sawan D, SidAhmed-Mezi M, et al.

Abstract
Platelet rich plasma (PRP) has trophic functions due to a high concentration of growth factors and cytokines. These properties may be of therapeutic interest in the management of burn injuries. In preparation for a clinical study at the Lyon Burn Centre on PRP as an inducer of healing in burns, we carried out a review of the literature looking at the results of the use of this therapy. A review of the literature on the use of PRP for the treatment of burn injuries was performed by querying the PUBMED database using the keywords [platelet rich plasma] AND [burns]. Controlled clinical or pre-clinical studies in English or French were included. Eleven articles were identified, consisting of eight preclinical animal model studies and three clinical studies. These looked at the effects of PRP on the healing of burned areas whether they were grafted or not, on the improvement of neuropathic pain, and on distant skin trophicity. The results of recent preclinical studies show shorter epithelialization times thanks to PRP. In humans, a significant study (201 patients) validates its use in combination with thin skin grafts, and another shows benefits on distant cutaneous trophicity. In conclusion, the use of PRP topically or by injection under the skin has a potential benefit in the management of acute burns. A large-scale series validates its use in clinical practice.

Abstract
BACKGROUND In recent years, platelet-rich plasma (PRP) has been used in burn wound repair, plastic surgery, bone and tendon ligament injury repair and other treatment at home and abroad. Clinical studies indicate that PRP has a good curative effect on repairing burn wounds. The residual wounds formed after large area severe burns are difficult to cure and have recurrent attacks. Because the action mechanism of PRP is unclear, its clinical efficacy of PRP in repairing severe burn wounds is controversial. And there is no relevant systematic evaluation of PRP in repairing severe burn wounds now. OBJECTIVE Meta analysis was used to evaluate the efficacy and safety of PRP in repairing severe burn wounds. METHODS Randomized controlled clinical trial of using PRP to repair severe burn wounds were retrieved by computer WanFang, China National Knowledge Infrastructure, China Science and Technology Journal Database, China Biology Medicine disc, Embase, PubMed, Web of Science and Cochrane Library from the establishment of the database to September 2020. Two researchers independently extract data and assess the quality of the included literature, and Meta analysis of the included literature is carried out by using RevMan5.3 software. RESULTS In this study, the efficacy and safety of PRP in repairing severe burn wounds are evaluated from the aspects of wound healing rate, wound healing time, scar index, visual simulation score, the number of layers of dressing, the number of times of changing gauze, frequency of dressing change, the positive rate of wound bacterial culture and the incidence of inflammatory reaction. CONCLUSIONS PRP has a good curative effect on the repair of severe burn wounds. This study provides reliable evidence for the clinical use of PRP in the clinical repair of severe burn wounds.

Abstract
Natural products are favored because of their non-toxicity, low irritants, and market reacceptance. We collected examples, according to ancient wisdom, of natural products to be applied in transdermal delivery. A transdermal delivery system, including different types of agents, such as ointments, patches, and gels, has long been used for skin concerns. In recent years, many novel transdermal applications, such as nanoemulsions, liposomes, lipid nanoparticles, and microneedles, have been reported. Nanosized drug delivery systems are widely applied in natural product deliveries. Nanosized materials notably enhance bioavailability and solubility, and are reported to improve the transdermal permeation of many substances compared with conventional topical formulations. Natural products have been made into nanosized biomaterials in order to enhance the penetration effect. Before introducing the novel transdermal applications of natural products, we present traditional methods within this article. The descriptions of novel transdermal applications are classified into three parts: liposomes, emulsions, and lipid nanoparticles. Each section describes cases that are related to promising natural product transdermal use. Finally, we summarize the outcomes of various studies on novel transdermal agents applied to skin treatments.

Abstract
BACKGROUND Neuropathic pain following injury or dysfunction of the peripheral or CNS is one of the most important medical challenges to treat. Humane platelet-rich plasma (HPRP), which is a rich source of growth factors, may be able to treat and reduce pain caused by spinal cord injury (SCI). In this study, the effect of HPRP on neuropathic pain caused by SCI was investigated. METHODS Sixty adult male Wistar rats were randomly divided into 6 groups: control, sham, SCI, vehicle (SCI+platelet-poor plasma), SCI+ PRP2day (injection 48 hrs after SCI) and SCI+PRP14day (injection 14 days after SCI). SCI was induced at the T12-T13 level. Behavioral tests were conducted weekly after injury for six weeks. Allodynia and hyperalgesia were assessed using acetone drops, plantar test and von Frey filament. Cavity size and the number of fibroblasts were determined by H&E stain, and the expression of mTOR, p-mTOR, P2×3R and P2Y4R were determined using the western blot technique. Data were analyzed using PRISM & SPSS software. RESULTS PRP injection showed a higher pain threshold in mechanical allodynia (p<0.0001), cold allodynia (p<0.0001) and thermal hyperalgesia (p<0.0001) than those in the spinal. Animals treated with PRP also reduced cavity size, fibroblast number, p-mTOR/mTOR ratio, and P2×3R expression, and increased P2Y4R expression. The difference between the two groups was not statistically significant. CONCLUSIONS The results showed that PRP reduced SCI-induced allodynia and hyperalgesia by regulating ATP signaling. Using HPRP can open a new window in the treatment of pain caused by damage to the nervous system.

Abstract
Context Surgical correction of scars may not be an ideal solution in all cases and hence it is desirable to have a nonsurgical option available. Autologous platelet-rich plasma (PRP) and fractional carbon dioxide laser (FCL) offer an alternative treatment modality. Aims To compare the efficacy and safety of FCL and intradermal PRP with FCL in the management of postburn and posttraumatic scars. Settings and Design A prospective, randomized, observer-blinded, comparative study was conducted at a hospital skin centre from Oct 2016 to Sep 2018. Subjects and Methods A total of 67 patients with scars were randomly divided into two groups; Group I was treated with four sessions of monthly FCL and Group II was treated with four sessions of PRP and FCL. The patients were assessed using the Patient and Observer Scar Assessment Scale (POSAS) at baseline and 4 weeks after each session. Statistical Analysis Used For continuous variables, the summary statistics of mean ± standard deviation was used; for categorical data, number and percentage were used. Chi-square (χ2) test was used for association between two categorical variables. P value <0.05 was considered to be statistically significant. Results Thirty cases in each group completed the study. There was a significant improvement in the total score of POSAS (p < 0.001) in both groups, but the final difference between the two groups was not statistically significant (p = 0.793 and P = 0.278, respectively). Conclusions Fractional CO2 laser causes significant improvement in scar appearance. PRP in combination with FCL offers no additional advantage.

The analgesic effects of pioglitazone in the bone cancer pain rats via regulating the PPARγ/PTEN/mTOR signaling pathway in the spinal dorsal horn. Biomed Pharmacother 2020; 131:110692. [PMID: 32942156 DOI: 10.1016/j.biopha.2020.110692] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2020] [Revised: 08/24/2020] [Accepted: 08/25/2020] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND AND OBJECTIVES Bone cancer pain (BCP) remains a difficult clinical problem. This study examined whether pioglitazone, a peroxisome proliferator-activated receptor gamma (PPARγ) agonist, is effective for attenuating BCP, and investigated the interaction between activation of PPARγ and phosphatase and tensin homolog deleted from chromosome 10 (PTEN) / mammalian target of rapamycin (mTOR) signal in the spinal dorsal horn (SDH) of BCP rats. METHODS We tested the effects of intrathecal (i.t.) injection of adenovirus-mediated PTEN (Ad-PTEN), PTEN antisense oligonucleotide (Ad-antisense PTEN), mTOR inhibitor rapamycin, pioglitazone and PPARγ antagonist GW9662 on bone cancer-induced mechanical allodynia by measuring the paw withdrawal threshold (PWT). Western blot or immunofluorescence examined the expression of spinal PPARγ, PTEN, mTOR, p-mTOR and p-S6K1. RESULTS Bone cancer did not alter total mTOR expression but caused significant downregulation of PTEN and upregulation of p-mTOR and p-S6K1 in spinal neurons. Rapamycin markedly reduced BCP. Upregulation of spinal PTEN by i.t. Ad-PTEN significantly relieved BCP and downregulated p-mTOR and p-S6K1; while i.t. Ad-antisense PTEN led to the opposite effects of Ad-PTEN. Spinal PPARγ expression increased in BCP rats, co-localizing mainly with neurons and a few astrocytes, but not in microglia. Pioglitazone (500 μg/day i.t. for one week, from 7 days after surgery) attenuated BCP, further increased expression of PPARγ, and inhibited downregulation of PTEN and upregulation of p-mTOR and p-S6K1 in the SDH. Pioglitazone's analgesic effect was enhanced by Ad-PTEN and attenuated by Ad-antisense PTEN. Blockade of PPARγ with GW9662 (300 μg i.t. 15 min prior to pioglitazone) reversed the effects of pioglitazone on BCP and regulations of PPARγ/PTEN/mTOR signal. CONCLUSIONS Intrathecal pioglitazone administration alleviates BCP by regulating the PPARγ/PTEN/mTOR signal in the SDH. Our data provided new insight in the therapeutic strategy in BCP management.

J Cosmet Dermatol 2019; 19:1607-1613. [PMID: 31709744 DOI: 10.1111/jocd.13212] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2019] [Revised: 09/10/2019] [Accepted: 10/17/2019] [Indexed: 12/24/2022]
Abstract
BACKGROUND Normal healing process becomes severely dysregulated in pathophysiological conditions such as inflammation, infection or underlaying diseases. These scenarios hamper the standard healing pattern and dermal fibrotic tissue develops. OBJECTIVE In the present study a novel three-dimensional formulation (Endoret-Gel) based on plasma rich in growth factors technology (Endoret-PRGF) has been assessed for atrophic scar management. MATERIALS AND METHODS Microstructure analysis, growth factor content, and projection capacity of both formulations (Endoret-Gel and Endoret-PRGF) was assessed. Additionally, a clinical evaluation of Endoret-Gel treatment was also performed in a case of an extense atrophic scar. RESULTS Endoret-Gel presented high molecular weight plasmatic proteins that formed solid thermal aggregates enclosed by a stable fibrin network. This formulation has a higher cutaneous projection capacity compared with Endoret-PRGF. Both formulations presented a high load of bioactive proteins such as EGF, PDGF-AB, and IGF-I being higher in liquid Endoret-PRGF. Clinical results evidenced that infiltrations of Endoret-Gel derived in an early volumetric disposal that was maintained for several months. The treatment provided and immediate soft tissue augmentation and scar amelioration effect that was translated into a noticeable clinical improvement of the injury. No side effects or adverse events were reported during ten-month follow-up period. CONCLUSION These preliminary findings suggest that Endoret-Gel may act not only as a temporary volumizer but also as soft tissue stimulator that might be used as a monotherapy for scar management.

Abstract
Platelet-rich plasma (PRP), a platelet concentrate contained in a small volume of plasma, has become a promising option in the last decade to treat different diseases related to the skin due to its high concentration of growth factors. When it is of autologous origin, it decreases the probability of suffering adverse reactions and transfusion-transmitted infections, thus it is an optimal and safe therapy for the patient. PRP has been used in the treatment of several dermatological conditions such as acne, alopecia, and skin ulcers. Its use has also extended to other skin conditions such as melasma, hyperpigmentation, and burns, where it stimulates tissue repair and regeneration. The purpose of this article is to review the management and treatment of different dermatological alterations with PRP. Although there are a variety of studies that support the use of PRP, more research is needed to standardise the protocols for obtaining, processing, and applying it as well as understanding the biological and molecular bases of its functioning.
