Compared with the model group, GEG increased cell viability as well as proliferation (P<0.05 or P<0.01) and reduced β -gal expression. Furthermore, GEG significantly decreased the expressions of p16
, p53 and p21
proteins, and increased the expressions of CDK2, CDK4 and pRb proteins compared with the model group (P<0.05 or P<0.01).
GEG can alleviate CTX-induced HSCs senescence in mice, and the p16
-Rb signaling pathway might be the underlying mechanism.

The shark family, Sphyrnidae, consists of nine species of which three are found in South African oceans. One of the three Sphyrnidae species, the scalloped hammerhead (Sphyrna lewini) are the most common, but their biology and mode of reproduction are not extensively studied in terms of their reproductive biology. The aim of this study was to describe the germ cell development in the testes of sexually mature male scalloped hammerheads. Three individual male S. lewini were caught at Zinkwazi, KwaZulu-Natal, South Africa. The sharks and their reproductive organs were weighed and measured to collect the biometric data for the condition factor and the gonado-somatic index. Following standard necropsy, the testes were fixed in Bouin's solution and processed for histological assessment. The histological assessment revealed that the testes of S. lewini consist of seminiferous tubules which form part of a larger lobular structure with germ cells in different stages of development, from spermatogonia to mature spermatozoa. Seven stages of development were identified during the process of spermatogenesis, similar to what has been described for elasmobranchs. In conclusion, this study provides evidence that the testes of S. lewini are diametrical and polyspermatocystic and conforms to the testes structure of elasmobranch males.
Some studies showed patients with chronic urticaria have a higher rate of peptic ulcer disease (PUD). Whether PUD is a risk factor for chronic urticaria is unclear.
The objective of this study was to evaluate the incidence of and risk factors for chronic urticaria in patients with PUD using the Taiwan National Health Insurance Research Database.
We conducted a retrospective nationwide cohort study of the period 2000-2012 and involving 11,901 patients with PUD who underwent Helicobacter pylori (HP) therapy (PUD + HP group) and an equal number of matched patients without HP infection (PUD-HP group). Furthermore, we enrolled 23,802 patients without PUD for comparison (non-PUD group). The Cox proportional hazards regression model was used to analyze chronic urticaria risk after adjusting for potential confounding factors.
The mean ages of the three groups were around 50years. Approximately 42.6% were female. Chronic urticaria incidences in the PUD + HP and PUD-HP groups were both significantly higher than that in the non-PUD group. The hazard ratios of chronic urticaria in the PUD + HP group and the PUD-HP group were 1.34 (95% confidence interval 1.09-1.64) and 1.45 (95% confidence interval 1.19-1.79), respectively. The risk difference became significant 2years after patients with PUD had the HP infection tests and persisted till the end of follow-up. The risk increase was significant in patients with PUD who were female or aged 40-64years. There was no difference in the risk comparison between PUD + HP and PUD-HP groups.
Peptic ulcer disease, independent of HP infection, is associated with an increased chronic urticaria risk. Patients with PUD who were female or aged 40-64years are more likely to have chronic urticaria.

There are a number of options for the symptomatic treatment of peripheral neuropathy, but the overall treatment outcomes remain unsatisfactory.
A total of 60 patients with refractory diabetic neuropathy were randomly assigned to two groups. Patients in Group A were treated with computed tomography (CT)-guided sympathetic neurolysis with alcohol, and patients in Group B were treated with a combined therapy of CT-guided catheterization to achieve continuous lumbar block for 4 weeks followed by neurolysis with alcohol administered via the catheter. The outcomes of these two treatment strategies were then analyzed in terms of pain relief, blood flow in the lower limb microcirculation, plasma levels of inflammatory mediators, and complications.
The visual analog scale (VAS) pain scores of all patients after treatment decreased significantly at the different evaluation time points compared with pre-treatment values, with the intergroup analysis revealing that the VAS scores were lower in Group B patients thantinuous lumbar sympathetic block followed by neurolysis with alcohol provided more benefit in all assessed outcomes than sympathetic alcohol neurolysis alone. The results show that the procedures were associated with satisfactory safety outcomes and sustained analgesic effects, thereby providing clinical evidence supporting the use of this novel treatment for patients with painful diabetic neuropathy.An inflammatory myofibroblastic tumor (IMT) is a rare invasive soft tissue mass with intramuscular penetration that is primarily treated via a surgical procedure. However, with unclear boundaries and a high rate of relapse, there is no standard treatment for recurrence or unresectable tumors. It is noteworthy that approximately half of IMTs harbor genetic rearrangements of the anaplastic lymphoma kinase (ALK). ALK inhibitors have been used successfully in the treatment of IMTs with a variety of ALK fusions. Here, we present a case of a 15-year-old patient with IMT around the hip. Next-generation sequencing (NGS) revealed an LRRFIP1-ALK fusion, which has not yet been reported in the literature. Crizotinib, an ALK inhibitor, was effective in the treatment of this patient, indicating that ALK inhibitors may be effective for IMT with LRRFIP1-ALK fusions. #link# This report expands the list of gene fusions in IMTs and highlights a new target for treatment.Background Crenigacestat is a potent Notch inhibitor that decreases Notch signaling and its downstream biological effects. Here, we report the results from Part F of study 16F-MC-JJCA designed to evaluate the safety, pharmacokinetics (PK), and antitumor activity of crenigacestat with prednisone in advanced or metastatic cancer. The combination was planned to mitigate gastrointestinal toxicities. Methods Eligible patients (Study Part F) received crenigacestat loading dose (75 mg, escalating to 150 mg) administered thrice weekly (TIW) (F1) or twice weekly (BIW) (F2) for 2 weeks during Cycle 1, followed by 50 mg TIW from week 3 onwards. Prednisone was co-administered for 2 weeks in Cycle 1. Results Twenty-eight patients were enrolled; 11 in F1 (median age, 63 years), 17 in F2 (median age, 50 years). Dose-limiting toxicities were Grade 3 increased serum amylase and Grade 2 fatigue in F1, and Grade 4 hypophosphatemia and Grade 3 rash maculo-papular in F2. The maximum tolerated dose was 75 mg in F1 and 100 mg in F2. Best overall response was stable disease (F1, 6 [54.5%] patients; F2, 11 [64.7%] patients). Pharmacokinetic was dose proportional. Prednisone did not modify PK of crenigacestat, and both F1 and F2 achieved pharmacodynamics effects on evaluable tumor tissue samples. Conclusions This study demonstrated the potential use of prednisone to reduce gastrointestinal (GI) toxicities of a Notch inhibitor without affecting its PK. The safety profile observed was consistent with Notch pathway inhibitors, and the maximum tolerated dose was 75 mg TIW and 100 mg BIW in F1 and F2, respectively.

New avenues, based on translational approaches and innovative validated biomarkers could be a preclinical option to evaluate PC drug candidates or drug combinations before clinical trials. Herein, we describe evaluation of combination therapies by incorporating a novel pathway modulator, p53-Activator Wnt Inhibitor-2 (PAWI-2) with other FDA-approved cancer drugs that have been used in PC clinical trials. PAWI-2 is a potent inhibitor of drug-resistant PC cells that has been shown to selectively ameliorate human pancreatic cancer stem cells (i.e., hPCSCs, FGβ3 cells). In the present study, we showed PAWI-2 produced therapeutic synergism with certain types of anti-cancer drugs. These drugs themselves oftentimes do not ameliorate PC cells (especially PCSCs) due to high levels of drug-resistance. PAWI-2 has the ability to rescue the potency of drugs (i.e., erlotinib, trametinib) and inhibit PC cell growth. Key molecular regulators of PAWI-2 could be used to predict synergistic/antagonistic effects between PAWI-2 and other anti-cancer drugs. Anti-cancer results showed potency could be quite accurately correlated to phosphorylation of optineurin (OPTN) in PC cells. link2 Synergism/antagonism was also associated with inhibition of PCSC marker SOX2 that was observed in FGβ3 cells. Synergism broadens the potential use of PAWI-2 as an adjunct chemotherapy in patients with PC that have developed resistance to first-line targeted therapies or chemotherapies.Stress is considered as an important risk factor in the progression and the onset of many disorders such as multiple sclerosis. However, metabolite changes as a result of demyelination under the detrimental effects of stress are not well understood. Thus, 36 female Wistar rats (i.e., groups (1) no-cuprizone (Cont), (2) no-stress + cuprizone-treated (Cup), (3) physical stress + cuprizone-treated (P-Cup), (4) psychological stress + cuprizone-treated (Psy-Cup), (5) physical stress + no-cuprizone-treated (P), (6) psychological stress + no-cuprizone-treated (Psy)) were used in this study. Following induction of repetitive stress, cuprizone treatment was carried out for 6 weeks to instigate demyelination in all groups except the control animal. Relative metabolite concentrations of the brain were investigated by single-voxel proton magnetic resonance spectroscopy (reporting N-acetyl-aspartate (NAA), glycerophosphocholine with phosphocholine (tCho) relative to total creatine (tCr)). According to 1H-MRS, rats in the Cup group indicated a reduction in NAA/ tCr (p less then 0.001) as well as tCho/ tCr (p less then 0.05) compared with that in the Cont group. In contrast, in both stress + cuprizone-treated groups, NAA/tCr and tCho/tCr ratios remarkably increased versus the Cup group (p less then 0.001) and the Cont group (p less then 0.001 for the Psy-Cup group and p less then 0.05 for the P-Cup group). link3 Both P and Psy groups revealed normal metabolite concentrations similar to the Cont group 6 weeks post stress. Seemingly, in the case of cuprizone alone, decreased level of metabolites is mainly relevant to neuronal cell impairments. Meanwhile, as a result of oxidative stress enhancement due to stress exposure, oligodendrocyte becomes the main victim indicating the increased level of metabolite ratios.
