Deep brain stimulation of the subthalamic nucleus (STN-DBS) stimulation produces significant improvement of overall pain related to Parkinson disease; however, the mechanisms underlying analgesic effects of STN-DBS are still unknown. This report describes direct neuroanatomical evidence for the central melanocortinergic-opioidergic circuits in the STN. We investigated melanocortin-4 receptor (MC4R) and mu-opioid receptor (MOR)-positive expression of the STN in MC4R-GFP transgenic mice using fluorescence immunohistochemical detection. Immunohistochemistry showed a large number of MC4R-GFP- and MOR-positive neurons within the STN region, and approximately 50% of MC4R-GFP-positive neurons coexpressed MOR. The results of this study showed direct neuroanatomical evidence for the central melanocortinergic-opioidergic signaling in the STN region. These findings contribute to the view of melanocortinergic-opioidergic circuits in the subthalamic nucleus as a reliable source of modulating of nociception with therapeutic potential for alleviating pain.

Rationale: MicroRNAs (miRNAs) are emerging as important regulators of allergic inflammation and potential therapeutic targets. We sought to identify which miRNAs are expressed in CD4+ T-cells and determine whether allergic stimuli or glucocorticoids alter their expression.
Methods: After IRB approval, blood was collected from dust mite (DM) allergic rhinitis subjects (n=20), non-allergic controls (n=8), and asthmatics (n=16). Peripheral blood mononuclear cells were incubated with dust mite extract (DME), diluent control, or DME + dexamethasone (0.1 µM). CD4+ T-cells were collected by magnetic bead column, and RNA was isolated by guanidinium/phenol-chloroform extraction. MicroRNA expression was measured using Nanostring microarray and quantitative real time PCR (qPCR).
Results: We identified 196 miRNAs that were stably expressed in circulating CD4+ T-cells. Allergen stimulation of CD4+ T-cells with DME differentially induced miR-155 expression in cells of DM-allergic subjects as compared to non-allergic subjects. Induction of miR-155 expression was also observed with anti-CD3/anti-CD28 simulation and phorbol-12-Myristate-13-Acetate (PMA) treatment, and further augmented by calcium inophore and bromocyclic AMP in the latter treatment. The level of miR-155 expression was positively associated with expression of the TH2 cytokines IL-5 and IL-13. Inhibition of miR-155 in Jurkat T-cells inhibited the production of these cytokines. Glucocorticoids attenuated the effects of dust mite allergen, raising the possibility that inhibition of this miRNA could be a mechanism through which glucocorticoids exhibit their anti-inflammatory effects. The CD4+ T-cells had a higher level of miR-155 expression in asthma compared to in allergic rhinitis and non-asthmatics. The inhibitory effects of glucocorticoids on CD4+ T-cell miR-155 expression were lost in severe asthmatics.
Conclusion: Mir-155 is differentially expressed in allergic T-cells exposed to DM extract compared to in non-allergic cells and it is inhibited by glucocorticoids. MiR-155 may play a role in mediating allergic inflammation in T-cells and could be an anti-inflammatory target of steroids. This pathway may be de-regulated in severe asthma.

To determine the potential changes of IL-6, IL-17A and IL-21 levels during induction therapy, and to assess their relationship with disease activity and immunologic features on patients with active lupus nephritis, twenty-eight patients treated with corticosteroid and immunosuppressants were included in this study. Demographic, clinical, serological data and disease activity were assessed. Blood samples were collected at week 0, 12 and 24, and serum concentrations of IL-17A, IL-6 and IL-21 were measured by cytometric bead array. The serum concentrations of IL-6, IL-17A and IL-21 (P<0.001, P<0.01, P=0.001, respectively) decreased progressively during induction therapy. Concentration of IL-6, IL-17A and IL-21 was higher in non-remission group than that in remission group. A positive correlation was established between the concentration of these cytokines and the severity of proteinuria (P<0.001, P=0.020, P=0.045, respectively), ESR (P<0.001), SLEDAI scores (P<0.05), and ANA titers (P=0.018, P=0.048, P<0.05, respectively). Additionally, ROC curve analysis for IL-6, IL-17A and IL-21 was performed to predict the disease activity. The optimal cutoff level was 5.78 pg/ml, 1.98 pg/ml and 8.59 pg/ml, with AUC=0.809, 0.735 and 0.786. The concentration of IL-6 and IL-21 may be regarded as an indicator for the remission of active lupus nephritis, with cutoff value of 9.12 pg/ml and 11.30 pg/ml, while AUC=0.930 and 0.896. The production of serum IL-6, IL-17A and IL-21 in active LN was dramatically declined during induction therapy, which may improve disease activity while delay disease progression of LN.

Icariin (ICA) is a major bioactive monomer belonging to flavonoid glycosides attracted from Epimedium, being a classic tonic agent in traditional Chinese medicine. ICA commonly presents multiple effects such as regulating sex hormones, relieving atherosclerosis and antioxidant activity, etc. Recently, more and more studies have demonstrated the application of ICA in autoimmune diseases such as rheumatoid arthritis, bronchial asthma, multiple sclerosis and systemic lupus erythematosus due to its anti-inflammatory. Additionally, ICA also has the anti-tumor activities. Multiple targets and mechanisms of ICA are reported which relates to regulate lymphocytes balance, anti-inflammatory/inflammatory cytokines, signal pathways like NF-kappaβ and Erk-p38-JNK, lymphocyte transcription factors and other targets such as TLRs, STAT and PTEN, etc. In this review, we have updated the advance in this field and these studies have suggested that ICA has a potential to treat immunological and inflammatory diseases.

Macrophages play critical roles in inflammatory initiation, development, resolution and cardiac regeneration of myocarditis. However, Reg3β, as a member of regenerating family of proteins, contributes to dedifferentiation of injury cardiomyocytes as well as cardiac function remodeling. It remains unclear whether Reg3β was associated with macrophages reprogramming during autoimmune myocarditis. Our results showed that Reg3β could effectively recruit macrophages, promoted their proliferation and phagocytosis, and facilitated their polarized into M2 macrophages. Macrophage, especially M1 phenotype contributed to Reg3β production by cardiomyocytes. Our data also indicated that Reg3β was involved in self-protection mechanism following cardiac injury or stress. This suggests that Reg3β might be a critically protective factor of myocardium.

To investigate autonomic substrates of brainstem-gut circuitry identified using trans-synaptic tracing with pseudorabies virus (PRV)-152, a strain that expresses enhanced green fluorescent protein, and PRV-614, a strain that expresses enhanced red fluorescent protein, injecting into the rat rectum wall. 3-7 days after PRV-152 injection, spinal cord and brainstem were removed and sectioned, and processed for PRV-152 visualization using immunofluorescence labeling against PRV-152. 6 days after PRV-614 injection, brainstem was sectioned and the neurochemical phenotype of PRV-614-positive neurons was identified using double immunocytochemical labeling against PRV-614 and TPH. We observed that the largest number of PRV-152- or PRV-614-positive neurons was located in the gigantocellular reticular nucleus (Gi), lateral paragigantocellular (LPGi), rostral ventrolateral reticular nucleus (RVL), solitary tract nucleus (Sol), locus coeruleus (LC), raphe magnus nucleus (RMg), subcoeruleus nucleus (SubCD). Double-labeled PRV-614/tryptophan hydroxylase (TPH) neurons were concentrated in the RMg, LPGi and Sol. These brainstem neurons are candidates for relaying autonomic command signals to the gut. The autonomic substrate of brainstem-gut circuitry likely plays an important role in mediating different aspects of stress behaviors.

Objective: The aim of this study was to investigate the associations between HSP90B1 gene polymorphisms and the efficacy of glucocorticoids (GCs) and the improvement of health-related quality of life (HRQoL) in Anhui patients with systemic lupus erythematosus (SLE). Method: A total of 305 patients with SLE were recruited to the study. These patients were treated with GCs for 12 weeks and classified into two groups (sensitivity and insensitivity) according to the response to GCs measured by the scores on SLE disease activity index (SLEDAI). The HRQoL of SLE patients were evaluated by 36-item Short Form Health Survey (SF-36) at baseline and 12 weeks respectively. HapMap database and Haploview software were used to select HSP90B1 gene tag single nucleotide polymorphisms (SNPs). Benjamini & Hochberg (BH) method based on false discovery rate (FDR) was used for multiple testing correction. Results: A total of 291 patients were included in final data analysis with 14 patients excluded due to loss to follow-up. Among these patients, 160 patients were sensitive to GCs and 131 patients were insensitive to GCs. Twelve tag SNPs of HSP90B1 gene were selected. The rs12426382 polymorphism was associated with the efficacy of GCs (dominant model: crude OR=0.514, 95% CI=0.321-0.824, P=0.006; adjusted OR=0.513, 95% CI=0.317-0.831, P=0.007). After BH correction, there was no association between rs12426382 polymorphism and efficacy of GCs (PBH =0.084). In haplotype analysis, the haplotype CCCGAACATCCC (OR=2.273, 95% CI=1.248-4.139, P=0.006) and CTGGGACGTTC (OR=0.436, 95% CI=0.208-0.916, P=0.025) showed significant associations with the efficacy of GCs. After corrected by BH method, CCCGAACATCCC was still associated with the efficacy of GCs (PBH =0.048). The rs3794241, rs1165681, rs2722188, rs3794240 and rs10861147 polymorphisms were associated with the improvement of HRQoL among SLE patients (P < 0.05). But no association existed after the correction of BH method (P > 0.05). Conclusions: The results of this study demonstrated that HSP90B1 genetic polymorphisms might be associated with the efficacy of GCs, but not associated with the improvement of HRQoL in Anhui population with SLE.

Osteoporosis (OP) and osteoporotic fractures are becoming a serious health care issue in the world. Calcium and vitamin D are the basic treatment for osteoporosis. Nonetheless, they do not effectively reduce the incidences of fracture. Currently approved treatments for osteoporosis include selective estrogen receptor modulators (SERMs), bisphosphonates, denosumab, teriparatide, calcitonin and others. However, the appearance of some adverse effects including atypical fracture and breast cancer has limited long-term treatments above mentioned. Therefore, treatment decision should be made on an individual basis, taking into account the relative benefits and risks in different patients. Bone metabolism test helps to assess the patient's condition, which may ultimately lead to therapeutic options and better clinical outcomes.
骨质疏松症(OP)和骨质疏松性骨折正成为全球严重的医疗保健问题。钙和维生素 D 是治疗骨质疏松症的基本药物。然而,它们并不能有效降低骨折的发生率。目前获批的骨质疏松症治疗方法包括选择性雌激素受体调节剂(SERMs)、双磷酸盐、地诺单抗、特立帕肽、降钙素等。然而,非典型骨折和乳腺癌等不良反应的出现限制了上述药物的长期治疗。因此,治疗决定应根据个体情况做出,并考虑到不同患者的相对益处和风险。骨代谢检测有助于评估患者的病情,最终可能会为患者提供治疗方案和更好的临床疗效。

Posterior reversible encephalopathy syndrome (PRES) is a rare clinical entity associated with systemic lupus erythematosus which characterized by seizure, headache, and altered mental status. The pathophysiology involves subcortical vasogenic edema secondary to hypertension and endothelial damage. PRES is reversible with withdrawal of the offending agent, strict blood pressure control, and treating the underlying disease. We report present here a patient with lupus nephritis who developed PRES following mycophenolate administration.

The Background: Diacerein has been proposed as a treatment option for management of type 2 diabetes due to its anti-inflammatory properties.
Purpose: The aim of this systematic review and meta-analysis of randomized controlled trials (RCTs) is to examine the effect and safety of diacerein in patients with type 2 diabetes.
Data sources and study selection: We searched Pubmed, Embase, and Cochrane Library for RCTs published from database inception to September 2017.
Data extraction and data synthesis: Among 44 studies that were initially identified, four were eligible and were included in the following analysis. Diacerein significantly reduced fasting glycemia [weighted mean differences (WMD) -0.66, 95% confidence interval (95% CI) -1.16 to -0.16] and glycated hemoglobin A1c (HbA1c ) (WMD -0.85, 95% CI -1.44 to -0.26). And the patients with a diacerein supplementation duration of ≤12 weeks had a greater decrease of fasting glycemia and HbA1c than the supplementation duration of >12 weeks. Furthermore, compared with placebo, diacerein revealed a significant increase in the relative risk (RR) of gastrointestinal symptoms (RR=2.50, 95% CI: 1.10 to 5.65), especially in the study subgroup with supplementation duration of >12 weeks (RR=4.01, 95% CI: 2.32 to 6.95).
Limitations: The sample size was relatively small and the duration of included studies was short so that the treatment efficacy and safety for longer duration was unknown.
Conclusions: Although further studies are needed, our findings clearly provide support to the use of diacerein in the clinical management of subjects with type 2 diabetes.
