Gastrointestinal Dysfunction in Parkinson’s Disease: Neuro-Gastroenterology Perspectives on a Multifaceted Problem

Patients with Parkinson’s disease (PD) face a multitude of gastrointestinal (GI) symptoms, including nausea, bloating, reduced bowel movements, and difficulties with defecation. These symptoms are common and may accumulate during the course of PD but are often under-recognized and challenging to manage. Objective testing can be burdensome to patients and does not correlate well with symptoms. Effective treatment options are limited. Evidence is often based on studies in the general population, and specific evidence in PD is scarce. Upper GI dysfunction may also interfere with the pharmacological treatment of PD motor symptoms, which poses significant management challenges. Several new less invasive assessment tools and novel treatment options have emerged in recent years. The current review provides an overview and a practical approach to recognizing and diagnosing common upper and lower GI problems in PD, e.g., dyspepsia, gastroparesis, small bowel dysfunction, chronic constipation, and defecatory dysfunction. Management aspects are discussed based on the latest evidence from the PD and general populations, with insights for future research pertaining to GI dysfunction in PD.

The mediating effect was analyzed on the basis of the current situation analysis and correlation analysis.Results:The total scores of humanistic practice ability, job stressors and perceived professional benefits of midwives were (102.13 ± 25.91), (72.77 ± 14.49) and (138.23 ± 18.71) respectively. The job stressors of midwives were negatively correlated with humanistic practice ability ( r=-0.206, P<0.01), perceived professional benefits were positively related to humanistic practice ability ( r=0.289, P<0.001) and were negatively correlated with job stressors ( r=-0.507, P<0.001). Perceived professional benefits played a major mediating role in the influence of stressors on humanistic practice ability (the total standardized effect was -0.233, and the indirect effect was -0.144). Conclusions:Perceived professional benefits act as a main mediator between job stressors and humanistic practice ability in midwives. Managers should reduce job stressors, enhance perceived professional benefits, and promote the formation, development and practice of humanistic practice ability of midwives.

Suanzaoren Tang and Its Modified Formulas on Prevention and Treatment of Anxiety Disorders： A Review / 中国实验方剂学杂志

Suanzaoren Tang， as documented in the Synopsis of the Golden Chamber （《金匮要略》），consists of Ziziphi Spinosae Semen， Poria， Anemarrhenae Rhizoma， Chuanxiong Rhizoma， and Glycyrrhizae Radix et Rhizoma， and is indicated for dysphoria， consumptive disease， and insomnia. In modern clinical practice，in addition to sleep disorders，Suanzaoren Tang and its modified formulas can also be used to treat anxiety disorders， as well as insomnia，cardiac intervention，myocardial infarction， and other diseases combined with anxiety. It is also used in combination with other Chinese medicinal formulas （such as Zhizichi Tang，Ganmai Dazaotang，Baihe Zhimu Dihuangtang，and Jinlingzi San），western medicines （such as paroxetine，zopiclone，enalapril，amlodipine，metformin，and sertraline hydrochloride）， acupuncture， and acupoint application to treat anxiety， as well as cardiovascular neurosis，cancer，hypertension，type 2 diabetes， and other diseases combined with anxiety. As revealed by clinical treatment results， Suanzaoren Tang and its modified formulas can significantly reduce anxiety scores such as Hamilton Anxiety Rating Scale（HAMA） and Self-rating Anxiety Scale（SAS），and improve anxiety symptoms with significant efficacy and few side effects. As reported by experimental pharmacological studies， Suanzaoren Tang can regulate the content of neurotransmitters such as dopamine（DA），homovanillic acid（HVA），γ-aminobutyric acid（GABA），noradrenaline （NE），5-hydroxyindoleacetic acid （5-HIAA），glutamic acid（Glu），β-endorphin（β-EP），5-hydroxytryptamine（5-HT）， and nitric oxide （NO）in the brain， and mediate immune function by reducing the levels of inflammatory cytokines such as interleukin-1β（IL-1β）and tumor necrosis factor-α（TNF-α），enhancing the proliferation of B lymphocytes，phagocytosis of peritoneal macrophages， and down-regulating the proliferation of T lymphocytes. Besides， it can also regulate the endocrine level to allow the homeostasis of nervous system， endocrine system， and immune system by increasing adrenocorticotropic hormone（ACTH）and corticosterone（CORT）levels and up-regulating glucocorticoid receptor（GR）expression， finally achieving the effect of anxiety prevention and treatment. The present study systematically reviewed the clinical and basic research progress on the prevention and treatment of anxiety with Suanzaoren Tang to provide references for the research on the mechanism and material basis of Suanzaoren Tang and the development of new drugs for anxiety.

Effects of saikosaponin b_2 on inflammation and energy metabolism in mice with acute liver injury induced by LPS/GalN / 中国中药杂志

To study the effects of saikosaponin b2( SS-b2) on inflammatory factors and energy metabolism against lipopolysaccharide/galactosamine( LPS/Gal N) induced acute liver injury in mice. Mice were randomly divided into normal group( equal amount of normal saline),model group( 100 g·kg~(-1) LPS and 400 mg·kg~(-1) Gal N),low,medium,high dose group of SS-b2( SS-b25,10,20 mg·kg~(-1)·d-1) and positive control group( dexamethasone,10 mg·kg~(-1)). All of the groups except for the normal group were treated with LPS/Gal N though intraperitoneally injection to establish the acute liver injury model. The organ indexes were calculated. The levels of serum transaminases( ALT and AST) and the activities of ATPase( Na+-K+-ATPase,Ca2+-Mg2+-ATPase) in liver were detected. The activity of tumor necrosis factor-α( TNF-α),interleukin-1β( IL-1β) and interleukin-6( IL-6) were determined by the enzyme-linked immunosorbent assay( ELISA). The contents of lactate dehydrogenase( LDH) in liver were determined by micro-enzyme method. HE staining was used to observe the histopathological changes of the liver. Histochemical method was used to investigate the protein expression of liver lactate dehydrogenase-A( LDH-A). The protein expressions of Sirt-6 and NF-κB in the liver were detected by Western blot. According to the results,compared with the model group,there were significant changes in organ indexes in the high-dose group of SS-b2( P<0. 05). The level of ALT,AST,TNF-α,IL-1β,IL-6 and the activities of LDH in serum of mice with liver injury were significantly reduced in the medium and high dose groups of SS-b2( P<0. 01). With the increase of the concentration of SS-b2,the range of hepatic lesions and the damage in mice decreased. The activities of Na+-K+-ATPase and Ca2+-Mg2+-ATPase in liver of mice were significantly enhanced in each dose group( P<0. 01). The expression of NF-κB in liver tissues was significantly down-regulated in the medium and high dose group( P<0. 01). Meanwhile,the expression of Sirt-6 protein in the liver of mice with acute liver injury was significantly increased in each dose group( P<0. 01).In summary,SS-b2 has a significant protective effect on LPS/Gal N-induced acute liver injury in mice,which may be related to the down-regulation of NF-κB protein expression and up-regulation of Sirt-6 protein expression to improve inflammatory injury and energy metabolism.

@#AIM: To investigate interocular differences in macular ganglion cell complex(mGCC)thickness in normal healthy subjects, and to determine cutoffs for interocular differences in mGCC thickness in normal healthy subjects.<p>METHODS: This was a cross-sectional study. mGCC thickness were measured in 236 healthy volunteers(472 eyes)using optical coherence tomography(OCT). The differences and the relationships of mGCC thickness between right and left eyes were analyzed. <p>RESULTS: For the right eyes, the mean average mGCC thickness was 91.99±6.61μm, and for the left, 91.75±9.93μm, with no significant difference. The mean mGCC thickness among superior and inferior in the right eye were 92.32±6.66μm and 91.27±8.87μm, respectively. The mean mGCC thickness among superior and inferior in the left eye were 92.05±6.55 and 91.51±6.76μm, respectively. It is comparable between the two eyes at different area. The P2.5 and P97.5 percentiles of interocular difference for mean average mGCC thickness were -4.82μm and 4.36μm, for superior mGCC thickness, -5.79μm and 6.42μm, and for inferior mGCC thickness, -7.21μm and 6.28μm. There was a strong correlation in the corresponding area between the right and left eyes for the mGCC thickness.<p>CONCLUSION: mGCC thickness shows significant interocular symmetry in normal subjects. Interocular difference exceeding the normal limits should be considered significantly asymmetrical, and may be indicative of glaucoma.

Superior colliculus-pulvinar-amygdala subcortical visual pathway and its biological significance / 生理学报

Superior colliculus-pulvinar-amygdala pathway is one of the subcortical visual pathways in mammalian brain. Some recent studies suggest that this pathway is involved in processing emotion-related visual information. This review discusses the possibility that this pathway is more related to visual alert rather than simply the early visual information processing. The biological significance of this pathway is also discussed. Instead of detecting "where" or "what" the visual target is, the task of this early visual stage is to send out a warning signal, i.e., "something appears", so that the brain can be set up in a state of alert, which is important for the survival of animals. Thus, in the early visual information process, detection of new object "emerging" or "disappearing" takes priority over the acquisition of its feature information of "texture" and "shape", etc. The subcortical pathway may provide the neural basis of early visual warning in topological perception, a biological significance critical for animal survival.

Anodal Transcranial Direct-Current Stimulation Over the Right Dorsolateral Prefrontal Cortex Influences Emotional Face Perception / 神经科学通报·英文版

The dorsolateral prefrontal cortex (DLPFC) is considered to play a crucial role in many high-level functions, such as cognitive control and emotional regulation. Many studies have reported that the DLPFC can be activated during the processing of emotional information in tasks requiring working memory. However, it is still not clear whether modulating the activity of the DLPFC influences emotional perception in a detection task. In the present study, using transcranial direct-current stimulation (tDCS), we investigated (1) whether modulating the right DLPFC influences emotional face processing in a detection task, and (2) whether the DLPFC plays equal roles in processing positive and negative emotional faces. The results showed that anodal tDCS over the right DLPFC specifically facilitated the perception of positive faces, but did not influence the processing of negative faces. In addition, anodal tDCS over the right primary visual cortex enhanced performance in the detection task regardless of emotional valence. Our findings suggest, for the first time, that modulating the right DLPFC influences emotional face perception, especially faces showing positive emotion.
