Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common and non-lethal urological condition with painful symptoms. The complexity of CP/CPPS’s pathogenesis and lack of efficient etiological diagnosis results in incomplete treatment and recurrent episodes, causing long-term mental and psychological suffering in patients. Recent findings indicate that the autonomic nervous system involves in CP/CPPS, including sensory, sympathetic, parasympathetic, and central nervous systems. Neuro-inflammation and sensitization of sensory nerves lead to persistent inflammation and pain. Sympathetic and parasympathetic alterations affect the cardiovascular and reproductive systems and the development of prostatitis. Central sensitization lowers pain thresholds and increases pelvic pain perception in chronic prostatitis. Therefore, this review summarized the detailed processes and mechanisms of the critical role of the autonomic nervous system in developing CP/CPPS.Furthermore, it describes the neurologically relevant substances and channels or receptors involved in this process, which provides new perspectives for new therapeutic approaches to CP/CPPS.

Objective To study the immunoadjuvant effects of chitosan oligosaccharide(COS),including the immune activation and the triggering of lysosomal escape,and to explore whether COS can be used as an adjuvant for attenuated live bacteria vector vaccines.Methods 1)Mouse macrophages RAW264.7 cells were cultured with COS at 0 mg/mL(the control group)and 0.1-4 mg/mL for 24 h and the effect on cell viability was measured by CCK8 assay.Mouse macrophages RAW264.7 were treated with COS at 0(the control group),1,2,and 4 mg/mL for 24 h.Then,the mRNA expression levels of the cytokines,including IFN-γ,IL-10,TGF-β,and TLR4,were determined by RT-qPCR assay.2)RAW264.7 cells were treated with 1 mL of PBS containing different components,including calcein at 50 μg/mL,COS at 2 mg/mL,and bafilomycin A1,an inhibitor,at 1 μmol/mL,for culturing.The cells were divided into the Calcein group,Calcein+COS group,and Calcein+COS+Bafilomycin A1 group accordingly.Laser scanning confocal microscopy was used to observe the phagocytosis and the intracellular fluorescence distribution of calcein,a fluorescent dye,in RAW264.7 cells in the presence or absence of COS intervention to determine whether COS was able to trigger lysosomal escape.3)LM?E6E7 and LI?E6E7,the attenuated Listeria vector candidate therapeutic vaccines for cervical cancer,were encapsulated with COS at the mass concentrations of 0.5 mg/mL,1 mg/mL,2 mg/mL,4 mg/mL,and 8 mg/mL.Then,the changes in zeta potential were measured to select the concentration of COS that successfully encapsulated the bacteria.Phagocytosis of the vaccine strains by RAW264.7 cells was measured before and after LM?E6E7 and LI?E6E7 were coated with COS at 2 mg/mL.Results 1)CCK8 assays showed that,compared with the findings for the control group,the intervention of RAW264.7 cells with COS at different concentrations for 24 h was not toxic to the cells and promoted cell proliferation,with the difference being statistically significant(P＜0.05).According to the RT-qPCR results,compared with those of the control group,the COS intervention up-regulated the mRNA levels of TLR4 and IFN-γ in RAW264.7 cells,while it inhibited the mRNA expression levels of TGF-β and IL-10,with the most prominent effect being observed in the 4 mg/mL COS group(P＜0.05).2)Laser scanning confocal microscopy revealed that the amount of fluorescent dye released from lysosomes into the cells was greater in the Calcein+COS group than that in the Calcein group.In other words,a greater amount of fluorescent dye was released from lysosomes into the cells under COS intervention.Furthermore,this process could be blocked by bafilomycin A1.3)The zeta potential results showed that COS could successfully encapsulate the surface of bacteria when its mass concentration reached 2 mg/mL.Before and after the vaccine strain was encapsulated by COS,the phagocytosis of LM?E6E7 by RAW264.7 cells was 5.70%and 22.00%,respectively,showing statistically significant differences(P＜0.05);the phagocytosis of LI?E6E7 by RAW264.7 cells was 1.55%and 6.12%,respectively,showing statistically significant differences(P＜0.05).Conclusion COS has the effect of activating the immune response of macrophages and triggering lysosomal escape.The candidates strains of coated live attenuated bacterial vector vaccines can promote the phagocytosis of bacteria by macrophages.Further research is warranted to develop COS into an adjuvant for bacterial vector vaccine.

The aim was to alleviate the "doctor-patient conflict" and create a harmonious medical environment.

To investigate the effects of molybdenum (Mo) and/or cadmium (Cd) on antioxidant function and the apoptosis-related genes in duck spleens. Sixty healthy 11-day-old ducks were randomly divided into six groups of 10 ducks (control, low Mo group, high Mo, Cd, low Mo + Cd, and high Mo + Cd groups). All were fed a basal diet containing low or high dietary doses of Mo and/or Cd. Relative spleen weight, antioxidant indices, apoptosis-related gene mRNA expression levels, and ultrastructural changes were evaluated after 120 days. The results showed that the relative spleen weight decreased significantly in the high Mo + Cd treatment group which compared with control group. Malondialdehyde levels increased and xanthine oxidase and catalase activities decreased in the Mo and/or Cd groups compared with levels in the control group. Bak-1 and Caspase-3 expressions were upregulated in the high Mo + Cd group, while Bcl-2 was downregulated. In addition, mitochondrial crest fracture, swelling, vacuolation, deformed nuclei, and karyopyknosis in both Mo + Cd treated groups were more severe than in the other groups. The results suggest that Mo and/or Cd can induce oxidative stress and apoptosis of spleen via effects on the mitochondrial intrinsic pathway. Moreover, the results indicate the two elements have a possible synergistic relationship.
