The latest clinical guidelines are mandatory for physicians to follow when practicing evidence-based medicine in the treatment of low back pain. Those guidelines should target not only Japanese board-certified orthopaedic surgeons, but also primary physicians, and they should be prepared based entirely on evidence-based medicine. The Japanese Orthopaedic Association Low Back Pain guideline committee decided to update the guideline and launched the formulation committee. The purpose of this study was to describe the formulation we implemented for the revision of the guideline with the latest data of evidence-based medicine.
The Japanese Orthopaedic Association Low Back Pain guideline formulation committee revised the previous guideline based on a method for preparing clinical guidelines in Japan proposed by Medical Information Network Distribution Service Handbook for Clinical Practice Guideline Development 2014. Two key phrases, "body of evidence" and "benefit and harm balance" were focused on in the revi 2019 clinical practice guideline for the management of low back pain was completed according to the latest evidence-based medicine. We strongly hope that this guideline serves as a benchmark for all physicians, as well as patients, in the management of low back pain.
Pulmonary vascular remodeling is the key pathological feature of pulmonary arterial hypertension (PAH) characterized by a pattern of lipid-related insulin resistance(IR), hormonal derangements and metabolic reprogramming. Our previous studies have demonstrated osthole as natural coumarin compound derived from traditional Chinese medicine is a promising agent for the treatment of pulmonary vascular remodeling in PAH.
The present study sought to delineate lipid metabolic modulatory mechanism of osthole against pulmonary vascular remodeling by employing an interdisciplinary strategy.
Rat model with PAH induced with MCT and PASMCs proliferation model induced with PDGF-BB were established in this study. Serum and lung tissues were used to lipid-related IR, hormone related indexes, pulmonary vascular remodeling analysis. Then, lipid metabolic gene, key enzymes, metabolites and cell proliferation indexes were examined to investigate metabolic regulatory mechanism in vivo and vitro model of PAH.
Osthole signiism of osthole against pulmonary vascular remodeling.
Our findings revealed the function of miRNA-22-3p in PASMCs and demonstrated a novel mechanism that miRNA-22-3p as a regulator can be targeted by osthole to greatly restore dysregulated lipid metabolism thus to alleviate pulmonary vascular remodeling in PAH, which provides novel insight into the potential therapeutic target for PAH, further highlights the development potential of osthole derived new drug against PAH.

N-methyl-d-aspartate receptors (NMDARs) have been demonstrated to play central roles in stroke pathology and recovery, including dual roles in promoting either neuronal survival or death with their different subtypes and locations.
We have previously demonstrated that pseudoginsenoside-F11 (PF11) can provide long-term neuroprotective effects on transient and permanent ischemic stroke-induced neuronal damage. However, it is still needed to clarify whether NMDAR-2A (NR2A)-mediated pro-survival signaling pathway is involved in the beneficial effect of PF11 on permanent ischemic stroke.
PF11 was administrated in permanent middle cerebral artery occlusion (pMCAO)-operated rats. The effect of PF11 on oxygen-glucose deprivation (OGD)-exposed primary cultured neurons were further evaluated. The regulatory effect of PF11 on NR2A expression and the activation of its downstream AKT-CREB pathway were detected by Western blotting and immunofluorescence in the presence or absence of a specific NR2A antagonist NVP-AAMs demonstrate that PF11 can exert neuroprotective effects on ischemic stroke by inhibiting the activation of CAPN1 and subsequently enhancing the NR2A-medicated activation of AKT-CREB pathway, which provides a mechanistic link between the neuroprotective effect of PF11 against cerebral ischemia and NR2A-associated pro-survival signaling pathway.
The inflammatory state of diabetes promotes high platelet response and endothelial adhesion, which are the main risk factors for cardiovascular events. Tetramethylpyrazine (TMP) is an amide alkaloid isolated from the traditional Chinese medicine Rhizoma Ligustici Chuanxiong, which has been widely used in the clinical treatment of ischemic cardiovascular disease.
This study aimed to investigate whether TMP could alleviate diabetes-induced high platelet response and endothelial adhesion and the underlying mechanisms.
Type 2 diabetes mellitus (T2DM) rat model was established by high-fat feeding combined with low dose of streptozotocin. Rats in the TMP treatment group were administered with TMP (100 or 200mg/kg) for 21 days. Cultured human umbilical vein endothelial cells (HUVECs) were stimulated with glucose (5.5mM) to induce endothelial activation. The NOD-like receptor protein 3 (NLRP3) over- and low-expressing cell models were established via transfection of NLRP3 lentivirus plasmid into HUVECs. INF39 (and endothelial adhesion via inhibiting NLRP3 inflammasome activation in T2DM rats, which provide a new basis for the clinical prevention and treatment of diabetes-associated cardiovascular events.Noise trauma involves a plethora of mechanisms including reactive oxygen species, apoptosis, tissue damage, and inflammation. Recently, circadian mechanisms were also found to contribute to the vulnerability to noise trauma in mice, with greater damage occurring during their active phase (nighttime), when compared to similar noise exposures during their inactive phase (daytime). These effects seem to be regulated by mechanisms involving Bdnf responses to noise trauma and circulating levels of corticosterone (CORT). However, recent studies using different noise paradigms show contradicting results and it remains unclear how universal these findings are. Here we show that these findings differ even between substrains of mice and are restricted to a narrow window of noise intensity. We found that CBA/Sca mice exposed to 103 dB SPL display differential day/night noise sensitivity as measured by auditory brainstem responses (ABRs), but not at 100 (where full recovery is observed in day or night exposed mice) or 10suggests that the differential vulnerability to noise trauma between inactive and active phase is not universal and is as sensitive as substrain differences that might be governed by the circadian amplitude of the circulating CORT profiles.Jorge Lobo's disease (JLD) is a chronic, granulomatous fungal infection caused by the traumatic implantation of the fungus Lacazia loboi in the cutaneous and subcutaneous tissues, with the presence of isolated nodular and coalescent keloidal lesions. Malignant degeneration is rare. This case report describes a 64-year-old male patient with JLD for 30-years who showed a change in the aspect of a lesion in the left lower limb. Histopathological examination confirmed the progression to well-differentiated squamous cell carcinoma (SSC). JLD is highly prevalent in tropical and subtropical regions, requiring monitoring concerning the transformation into SSC in long-term lesions.Lichen nitidus is an uncommon lichenoid dermatosis that could be defined as multiple, separated, shiny, pinpoint, pale to skin-colored papules. Palmoplantar lichen nitidus is a quite rare variant of lichen nitidus. It is hard to make a diagnosis of palmar lichen nitidus when there are no lesions elsewhere on the body. There are some dermoscopic features defined for both palmoplantar and non-palmoplantar lichen nitidus that might be useful to facilitate the diagnosis before histopathological examination. Aminocaproic cell line Herein, we report a case of a 24-year-old man diagnosed with isolated palmar lichen nitidus with dermoscopic features and histopathological confirmation.
The Japanese herbal medicine kyoseihatekigan (KHG) has been used to alleviate the symptoms of croaky voice and globus hystericus, and each of its components has anti-inflammatory and antioxidant effects. However, the mechanisms underlying these beneficial actions of KHG on the vocal folds remain largely unknown. We examined the effects of KHG on rat vocal fold wound healing and assessed its anti-inflammatory and antioxidant properties.
Animal model.
The vocal folds of Sprague-Dawley rats were unilaterally injured under endoscopy. Rats were divided into three groups based on KHG dosing from pre injury day 4 to post injury day 3 0 mg/kg/day (sham group), 500 mg/kg/day (1% KHG group) and 1000 mg/kg/day (2% KHG group). Histologic changes were examined to assess the degree of inflammation and oxidative stress at day 3, and fibrosis at day 56. In addition, gene expression related to pro-inflammatory cytokines and transforming growth factor-beta1 (TGF-β1) signaling was examined by quantitative real-time polymerase chain reaction (qPCR).
Histologic analysis showed that the 1% and 2% KHG treatments significantly decreased cell infiltration and the 4-hydroxy-2-nonenalx-immunopositive area, and increased hyaluronic acid at day 3. Both KHG treatments significantly decreased fibrosis at day 56. qPCR revealed that mRNA of interleukin-1β and cyclooxygenase-2 were significantly suppressed at day 1 and TGF-β1 mRNA was significantly downregulated at day 5 in both KHG groups.
The current findings suggest that KHG has anti-inflammatory and antioxidant effects in the early phase of vocal fold wound healing, which can lead to better wound healing with less scar formation.

The current study aimed to translate, culturally adapt, and validate the Reflux Symptomatic Index in the Hindi language. Secondly, we aimed to compare its outcomes between normal individuals and people suffering from laryngopharyngeal reflux.
Cross-sectional study design.
The original Reflux Symptom Index was translated into Hindi language using the forward-backward translation method. A total of 192 participants were included in the study. Among 192 participants, 57 were healthy controls, and 135 were individuals with laryngopharyngeal reflux. Internal consistency, test-retest reliability, and clinical validity were measured.
The majority of the population reported the presence of globus sensation. Results revealed that the Hindi version of the Reflux Symptom Index exhibited an excellent internal consistency (ie, 0.829). A significant difference was found between the mean scores of both groups, and the excellent test-retest reliability score (ie, 0.94 & 0.96) was obtained.
We can conclude that the Hindi version of the Reflux Symptom Index exhibited a similar psychometric functional property as the Original version of the Reflux Symptom Index.
