Abstract
The existing treatments for somatoform dysfunction (SfD), reaction to severe stress (RSS), and adjustment disorders (AjD) are insufficiently effective and safe. Anxiolytic drug Tenoten proved effective in clinical trials (CT). The aim of this multicenter double-blind placebo-controlled randomized CT was to investigate the safety and efficacy of Tenoten in the treatment of anxiety in adults with SfD, RSS, AjD and other neurotic disorders (oNDs). 390 adult patients with SfD, RSS and AjD or oNDs with the Hospital Anxiety and Depression scale-anxiety (HADS-A) score ≥ 11 were randomized into 4 groups (n = 127 in Tenoten group 1 (4 tablets/day); n = 131 in Tenoten group 3 (8 tablets/day), n = 132 in combined Placebo group 2 + 4). The changes from baseline in the mean Hamilton Anxiety Rating Scale (HAM-A) score in groups 1 and 3 after 12 weeks were the primary outcome. The decrease of the HAM-A score from 18.81 ± 5.81 to 7.26 ± 4.63 (in group 1) and from 18.38 ± 4.3 to 6.40 ± 4.02 (in group 3) was observed post-treatment (pgroup 1/placebo = 0.0055, pgroup 3/placebo < 0.0001). Overall, 46 adverse events (28 in the Tenoten groups and 18 in the Placebo) were reported without any difference between the study groups. Tenoten performed significantly more effective than placebo in the anxiety treatment of adults with SfD, RSS, AjD and oNDs (clinicaltrials.gov NCT03036293).

Abstract
Vascular cognitive impairment (VCI) and vascular dementia are the most common forms of cognitive disorder associated with cerebrovascular disease and related to increased morbidity and mortality among the older population. Growing evidence suggests the contribution of blood-pressure variability, cardiac arrhythmia, hyperactivation of the renin-angiotensin-aldosterone system, endothelial dysfunction, vascular remodeling and stiffness, different angiopathies, neural tissue homeostasis, and systemic metabolic disorders to the pathophysiology of VCI. In this review, we focus on factors contributing to cerebrovascular disease, neurovascular unit alterations, and novel approaches to cognitive improvement in patients with cognitive decline. One of the important factors associated with the neuronal causes of VCI is the S100B protein, which can affect the expression of cytokines in the brain, support homeostasis, and regulate processes of differentiation, repair, and apoptosis of the nervous tissue. Since the pathological basis of VCI is complex and diverse, treatment affecting the mechanisms of cognitive disorders should be developed. The prospective role of a novel complex drug consisting of released-active antibodies to S100 and to endothelial NO synthase in VCI treatment is highlighted.

Abstract
We examined the effect of transplantation of allogenic adipose-derived stem cells (ADSCs) with properties of mesenchymal stem cells (MSCs) on posttraumatic sciatic nerve regeneration in rats. We suggested an approach to rat sciatic nerve reconstruction using the nerve from the other leg as a graft. The comparison was that of a critical 10 mm nerve defect repaired by means of autologous nerve grafting versus an identical lesion on the contralateral side. In this experimental model, the same animal acts simultaneously as a test model, and control. Regeneration of the left nerve was enhanced by the use of ADSCs, whereas the right nerve healed under natural conditions. Thus the effects of individual differences were excluded and a result closer to clinical practice obtained. We observed significant destructive changes in the sciatic nerve tissue after surgery which resulted in the formation of combined contractures in knee and ankle joints of both limbs and neurotrophic ulcers only on the right limb. The stimulation of regeneration by ADSCs increased the survival of spinal L5 ganglia neurons by 26.4%, improved sciatic nerve vascularization by 35.68% and increased the number of myelin fibers in the distal nerve by 41.87%. Moreover, we have demonstrated that S100, PMP2, and PMP22 gene expression levels are suppressed in response to trauma as compared to intact animals. We have shown that ADSC-based therapy contributes to significant improvement in the regeneration.

Abstract
In this study, we aimed to explore the role of ursolic acid in the neural regeneration of the injured sciatic nerve. BALB/c mice were used to establish models of sciatic nerve injury through unilateral sciatic nerve complete transection and microscopic anastomosis at 0.5 cm below the ischial tube-rosity. The successfully generated model mice were treated with 10, 5, or 2.5 mg/kg ursolic acid via intraperitoneal injection. Enzyme-linked immunosorbent assay results showed that serum S100 protein expression level gradually increased at 1-4 weeks after sciatic nerve injury, and significantly decreased at 8 weeks. As such, ursolic acid has the capacity to significantly increase S100 protein expression levels. Real-time quantitative PCR showed that S100 mRNA expression in the L4-6 segments on the injury side was increased after ursolic acid treatment. In addition, the muscular mass index in the soleus muscle was also increased in mice treated with ursolic acid. Toluidine blue staining revealed that the quantity and average diameter of myelinated nerve fibers in the injured sciatic nerve were significantly increased after treatment with ursolic acid. 10 and 5 mg/kg of ursolic acid produced stronger effects than 2.5 mg/kg of ursolic acid. Our findings indicate that ursolic acid can dose-dependently increase S100 expression and promote neural regeneration in BALB/c mice following sciatic nerve injury.

Abstract
BACKGROUND One major concern in about one third of elder patients after total hip-replacement surgery is post-operative cognitive dysfunction (POCD). Previous studies have suggested that cognitive impairment is accompanied with changes in serum S-100β protein (S-100β) and inflammatory markers. Thus, the aim of the current study was to investigate the value of serum S-100β and interleukin(IL)-1β, IL-6, tumour necrosis factor-α (TNF-α), and C-reactive protein (CRP) in reflecting POCD after total hip-replacement surgery. METHODS Forty-two elderly patients were enrolled, and 37 patients completed the follow-up. Serum S-100β protein and IL-1β, IL-6, TNF-α, and CRP were determined pre-operatively, as well as 1 h and 6 h post-operatively. Neuropsychological tests were performed pre-operatively, as well as on day 1, 3, and 7 post-operatively. RESULTS Seventeen (45.9%, 17/37) patients developed POCD 1 day after surgery, and three (8.1%, 3/37) developed POCD 7 days after surgery. [Correction added after publication 7 February 2012: in the preceding sentence (54.1%, 17/37) was corrected to (45.9%, 17/37)]. Patients with POCD 1 day after surgery had significantly higher serum levels of IL-6 at 6 h (135 ± 32 pg/ml vs. 91 ± 29 pg/ml, P < 0.05) and S-100β at 1 h (1872 ± 385 pg/ml vs. 1289 ± 143 pg/ml, P < 0.05. No significant post-operative change was detected in levels of TNF-α, IL-1, or CRP. CONCLUSION The serum levels of pro-inflammatory marker IL-6 and S-100β protein increased after total hip-replacement in elderly patients, and such increase may serve as predicting parameters for the occurrence of POCD.
