Regulation of primary cilia disassembly through HUWE1-mediated TTBK2 degradation plays a crucial role in cerebellar development and medulloblastoma growth.

Development of the cerebellum requires precise regulation of granule neuron progenitor (GNP) proliferation. Although it is known that primary cilia are necessary to support GNP proliferation, the exact molecular mechanism governing primary cilia dynamics within GNPs remains elusive. Here, we establish the pivotal roles for the centrosomal kinase TTBK2 (Tau tubulin kinase-2) and the E3 ubiquitin ligase HUWE1 in GNP proliferation. We show that TTBK2 is highly expressed in proliferating GNPs under Sonic Hedgehog (SHH) signaling, coinciding with active GNP proliferation and the presence of primary cilia. TTBK2 stabilizes primary cilia by inhibiting their disassembly, thereby promoting GNP proliferation in response to SHH. Mechanistically, we identify HUWE1 as a novel centrosomal E3 ligase that facilitates primary cilia disassembly by targeting TTBK2 degradation. Disassembly of primary cilia serves as a trigger for GNP differentiation, allowing their migration from the external granule layer (EGL) of the cerebellum to the internal granule layer (IGL) for subsequent maturation. Moreover, we have established a link between TTBK2 and SHH-type medulloblastoma (SHH-MB), a tumor characterized by uncontrolled GNP proliferation. TTBK2 depletion inhibits SHH-MB proliferation, indicating that TTBK2 may be a potential therapeutic target for this cancer type. In summary, our findings reveal the mechanism governing cerebellar development and highlight a potential anti-cancer strategy for SHH-MB.

Faecalibacterium taiwanense sp. nov., isolated from human faeces.

Two Gram-stain-negative, straight rods, non-motile, asporogenous, catalase-negative and obligately anaerobic butyrate-producing strains, HLW78T and CYL33, were isolated from faecal samples of two healthy Taiwanese adults. Phylogenetic analyses of 16S rRNA and DNA mismatch repair protein MutL (mutL) gene sequences revealed that these two novel strains belonged to the genus Faecalibacterium. On the basis of 16S rRNA and mutL gene sequence similarities, the type strains Faecalibacterium butyricigenerans AF52-21T(98.3-98.1 % and 79.0-79.5 % similarity), Faecalibacterium duncaniae A2-165T(97.8-97.9 % and 70.9-80.1 %), Faecalibacterium hattorii APC922/41-1T(97.1-97.3 % and 80.3-80.5 %), Faecalibacterium longum CM04-06T(97.8-98.0% and 78.3 %) and Faecalibacterium prausnitzii ATCC 27768T(97.3-97.4 % and 82.7-82.9 %) were the closest neighbours to the novel strains HLW78T and CYL33. Strains HLW78T and CYL33 had 99.4 % both the 16S rRNA and mutL gene sequence similarities, 97.9 % average nucleotide identity (ANI), 96.3 % average amino acid identity (AAI), and 80.5 % digital DNA-DNA hybridization (dDDH) values, indicating that these two strains are members of the same species. Phylogenomic tree analysis indicated that strains HLW78T and CYL33 formed an independent robust cluster together with F. prausnitzii ATCC 27768T. The ANI, AAI and dDDH values between strain HLW78T and its closest neighbours were below the species delineation thresholds of 77.6-85.1 %, 71.4-85.2 % and 28.3-30.9 %, respectively. The two novel strains could be differentiated from the type strains of their closest Faecalibacterium species based on their cellular fatty acid compositions, which contained C18 : 1 ω7c and lacked C15 : 0 and C17 : 1 ω6c, respectively. Phenotypic, chemotaxonomic and genotypic test results demonstrated that the two novel strains HLW78T and CYL33 represented a single, novel species within the genus Faecalibacterium, for which the name Faecalibacterium taiwanense sp. nov. is proposed. The type strain is HLW78T (=BCRC 81397T=NBRC 116372T).

Identification of key sensory and chemical factors determining flavor quality of Xinyu mandarin during ripening and storage.

Xinyu mandarin is popular for its good flavor, but its flavor deteriorates during postharvest storage. To better understand the underlying basis of this change, the dynamics of the sensory profiles were investigated throughout fruit ripening and storage. Sweetness and sourness, determined especially by sucrose and citric acid content, were identified as the key sensory factors in flavor establishment during ripening, but not in flavor deterioration during storage. Postharvest flavor deterioration is mainly attributed to the reduction of retronasal aroma and the development of off-flavor. Furthermore, sugars, acids and volatile compounds were analyzed. Among the 101 detected volatile compounds, 10 changed significantly during the ripening process. The concentrations of 15 volatile components decreased during late postharvest storage, among which α-pinene and d-limonene were likely to play key roles in the reduction of aroma. Three volatile compounds were found to increase during storage, associated with off-flavor development.

Development and validation of a clinical prediction model for early ventilator weaning in post-cardiac surgery.

Background: Weaning patients from mechanical ventilation is a critical clinical challenge post cardiac surgery. The effective liberation of patients from the ventilator significantly improves their recovery and survival rates. This study aimed to develop and validate a clinical prediction model to evaluate the likelihood of successful extubation in post-cardiac surgery patients. Method: A predictive nomogram was constructed for extubation success in individual patients, and receiver operating characteristic (ROC) and calibration curves were generated to assess its predictive capability. The superior performance of the model was confirmed using Delong's test in the ROC analysis. A decision curve analysis (DCA) was conducted to evaluate the clinical utility of the nomogram. Results: Among 270 adults included in our study, 107 (28.84%) experienced delayed extubation. A predictive nomogram system was derived based on five identified risk factors, including the proportion of male patients, EuroSCORE II, operation time, pump time, bleeding during operation, and brain natriuretic peptide (BNP) level. Based on the predictive system, five independent predictors were used to construct a full nomogram. The area under the curve values of the nomogram were 0.880 and 0.753 for the training and validation cohorts, respectively. The DCA and clinical impact curves showed good clinical utility of this model. Conclusion: Delayed extubation and weaning failure, common and potentially hazardous complications following cardiac surgery, vary in timing based on factors such as sex, EuroSCORE II, pump duration, bleeding, and postoperative BNP reduction. The nomogram developed and validated in this study can accurately predict when extubation should occur in these patients. This tool is vital for assessing risks on an individual basis and making well-informed clinical decisions.

Staphylococcus hsinchuensis sp. nov., Isolated from Soymilk.

A novel coagulase-negative Staphylococcus strain (H164T) was isolated from soymilk in Taiwan. Comparative sequence analysis of the 16S rRNA gene revealed that the H164T strain is a member of the genus Staphylococcus. We used multilocus sequence analysis (MLSA) and phylogenomic analyses to demonstrate that the novel strain was closely related to Staphylococcus gallinarum, Staphylococcus nepalensis, Staphylococcus cohnii, and Staphylococcus urealyuticus. The average nucleotide identity and digital DNA-DNA hybridization values between H164T and its closest relatives were <95% and <70%, respectively. The H164T strain could also be distinguished from its closest relatives by the fermentation of d-fructose, d-maltose, d-trehalose, and d-mannitol, as well as by the activities of α-glucosidase and alkaline phosphatase. The major cellular fatty acids were C15:0 iso and C15:0 anteiso, and the predominant menaquinones were MK-7 and MK-8, respectively. The major cellular fatty acids and predominant menaquinones were C15:0 iso and C15:0 anteiso and MK-7 and MK-8, respectively. In conclusion, this strain represents a novel species, named Staphylococcus hsinchuensis sp. nov., with the type strain H164T (=BCRC 81404T = NBRC 116174T).

Application of neutrophil-to-lymphocyte-to-monocyte ratio in predicting mortality risk in adult patients with septic shock: A retrospective cohort study conducted at a single center.

Background: Sepsis is a life-threatening condition characterized by an aberrant host response to infection, resulting in multi-organ dysfunction. The application of currently available prognostic indicators for sepsis in primary hospitals is challenging. In this retrospective study, we established a novel index, the neutrophil-to-lymphocyte-to-monocyte ratio (NLMR), based on routine blood examination upon admission, and assessed its prognostic value for early mortality risk in adult patients with septic shock. Methods: This study included clinical data from adult patients with septic shock who were admitted to the hospital between January 1, 2018, and December 31, 2022. Training and validation sets were constructed, and patients were categorized into "survival" and "death" groups based on their survival status within the 28-day hospitalization period. Baseline data, including demographic characteristics and comorbidities, and laboratory results, such as complete blood count parameters, were collected for analysis. The Sequential Organ Failure Assessment (SOFA) and Acute Physiology and Chronic Health Evaluation II (APACHE II) scores were documented.The NLMR was determined through the utilization of multivariate binary logistic regression analysis, leading to the development of a risk model aimed at predicting early mortality in adult patients suffering from septic shock. Results: Overall, 112 adult patients with septic shock were enrolled in this study, with 84 and 28 patients in the training and validation sets, respectively. Multivariate binary logistic analysis revealed that the neutrophil, lymphocyte, and monocyte counts independently contributed to the mortality risk (odds ratios = 1.22, 0.08, and 0.16, respectively). The NLMR demonstrated an area under the receiver operating characteristic curve (ROC-AUC) of 0.83 for internal validation in the training set and 0.97 for external validation in the validation set. Both overall model quality values were significantly high at 0.74 and 0.91, respectively (P < 0.05). NLMR exhibited a higher ROC-AUC value of 0.88 than quick SOFA (ROC-AUC = 0.71), SOFA (ROC-AUC = 0.83), and APACHE II (ROC-AUC = 0.78). Conclusion: NLMR may be a potential marker for predicting the risk of early death in adult patients with septic shock, warranting further exploration and verification.

[Mechanism of "Trichosanthis Fructus-Allii Macrostemonis Bulbus" in treating cardiovascular diseases with syndrome of combined phlegm and stasis based on serum metabolomics].

This study aimed at investigating the mechanism of Trichosanthis Fructus-Allii Macrostemonis Bulbus(GX) in treating cardiovascular diseases in rats with the syndrome of combined phlegm and stasis. The rat model was established by a high-fat diet, ice-water bath combined with subcutaneous injection of adrenalin hydrochloride, and the syndrome score was determined. The serum samples of rats in the control, model, and GX groups were collected. Ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was employed to analyze the metabolic profiles of the serum samples. The differential metabolites were screened and identified by partial least squares-discriminant analysis(PLS-DA) and orthogonal partial least squares-discriminant analysis(OPLS-DA). The intervention targets of GX-regulated metabolites and their metabolic pathways were searched against MetaboAnalyst. Gene Ontology enrichment was carried out to predict the biological pathways associated with the intervention targets of metabolic pathways. A total of 129 potential biomarkers were detected in the rat model with the syndrome of combined phlegm and stasis via metabolomics, and GX regulated 54 metabolites in several metabolic pathways such as linoleic acid metabolism, sphingolipid metabolism, and tricarboxylic acid cycle. The further screening against MetaboAnalyst showed that GX recovered the levels of nine metabolites associated with cardiovascular diseases with the syndrome of combined phlegm and stasis, which involved 69 targets in the pathways regarding cholesterol metabolism, fatty acid metabolism, inflammatory response, and glucose homeostasis and metabolism. The above-mentioned results suggested that GX can alleviate the symptoms of the rat model of cardiovascular diseases with the syndrome of combined phlegm and stasis by regulating the metabolism of linoleic acid, sphingosine, docosahexaenoic acid, rosemary acid, succinic acid, adenine, L-phenylalanine, L-valine and modulating the biological pathways such as cholesterol metabolism, fatty acid metabolism, inflammatory response, and glucose homeostasis and metabolism.

Multiple Eruptive Dermatofibroma: A Case Report.

Background: Multiple eruptive dermatofibroma (MEDF) is a rare presentation of dermatofibroma which is frequently associated with underlying diseases such as human immunodeficiency virus infection or systemic lupus erythematosus. It generally presents a characteristic histology with hyperplasia of the epidermis, prominent bundles of collagen and a diffuse proliferation of fibrocytes. Case Summary: We report a case of MEDF in a 30-year-old man who presented with a large number of dark brownish red maculopapules distributed over the trunk and extremities for more than 10 years. According to the pathology, the patient was diagnosed with MEDF. Infections and autoimmune diseases were ruled out. As he had no clinical symptoms, and presented with lesions widely distributed over the body, we gave no special treatment, but suggested a regular examination. Conclusion: Patients with MEDF usually have no pain and pruritus. If human immunodeficiency virus infection and systemic lupus erythematosus and other causes are ruled out, and lesions are widely distributed over the body, regular check-up is recommended without specific treatment.

Inhibition of colon C5a/C5a receptor signalling pathway confers protection against LPS-induced acute kidney injury via gut microbiota-kidney axis.

Acute kidney injury (AKI) is a critical condition often associated with systemic inflammation and dysregulated gut microbiota. This study aimed to investigate the effects of the C5a receptor antagonist W54011 on lipopolysaccharide (LPS)-induced AKI, focusing on the colon's C5a/C5a receptor pathway, intestinal barrier integrity, and gut microbiota. Our findings demonstrate that W54011 effectively ameliorated kidney injury in the LPS-induced AKI model by selectively inhibiting the colon's C5a/C5a receptor signalling pathway. Additionally, C5a receptor blockade resulted in the inhibition of colonic inflammation and the reconstruction of the intestinal mucosal barrier. Furthermore, W54011 administration significantly impacted the composition and stability of the gut microbiota, restoring the abundance of dominant bacteria to levels observed in the normal state of the intestinal flora and reducing the abundance of potentially harmful bacterial groups. In conclusion, W54011 alleviates LPS-induced AKI by modulating the interplay between the colon, gut microbiota, and kidneys. It preserves the integrity of the intestinal barrier and reinstates gut microbiota, thereby mitigating AKI symptoms. These findings suggest that targeting the colon and gut microbiota could be a promising therapeutic strategy for AKI treatment.

Clinical efficacy of rhGM-CSF gel and medical collagen sponge on deep second-degree burns of infants: A randomized clinical trial.

BACKGROUND: This study aimed to observe clinical efficacy of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) gel, medical collagen sponge and rhGM-CSF gel in combination with medical collagen sponge on deep second-degree burns of head, face or neck in infants. METHODS: A total of 108 infants with deep second-degree burns on head, face or neck were randomly divided into rhGM-CSF group, medical collagen sponge group, and rhGM-CSF + medical collagen sponge group. The scab dissolving time, healing time, bacterial positive rate and Vancouver scar scale were evaluated and analyzed. RESULTS: The data analysis showed that scab dissolving time and healing time were shorter in rhGM-CSF + medical collagen sponge group than that in rhGM-CSF group and medical collagen sponge group, and the difference was statistically significant (P < .05). Bacterial positive rate was lower in rhGM-CSF + medical collagen sponge group than that in rhGM-CSF group and medical collagen sponge group (P < .05). After 3 months, score of Vancouver scar scale (scar thickness, pliability, pigmentation and vascularity) was less in rhGM-CSF + medical collagen sponge group than that in rhGM-CSF group and medical collagen sponge group (P < .05). CONCLUSION: rhGM-CSF gel in combination with medical collagen sponge is significantly effective in treating deep second-degree burns of head, face or neck in infants. This combination is beneficial for infection control, acceleration of scab dissolving and wound healing, and reduction of scar hyperplasia and pigmentation, which is worthy of clinical application and promotion.

Efficacy of the spirit-regulation method of Jin's three-needle therapy for post-stroke anxiety and its effect on the hypothalamus-pituitary-adrenal axis. / 靳三针调神针法治疗卒中后焦虑的疗效观察及对下丘脑-垂体-è‚¾ä¸Šè ºè½´çš„å½±å“.

OBJECTIVES: To observe the clinical efficacy of the spirit-regulation method of Jin's three-needle therapy on post-stroke anxiety and its effects on the hypothalamus-pituitary-adrenal (HPA) axis. METHODS: Fifty-four patients with post-stroke anxiety were divided into spirit regulation (Jin's three needle therapy) group and sham-acupuncture group according to the random number table method, 28 cases in the spirit regulation and 26 cases in the sham-acupuncture group. The patients of the two groups received the same regimen of basic medication and rehabilitation, and the same acupoint prescription was adopted, including Sishenzhen (extra points, 1.5 cun to Baihui ［GV20］ at 3, 6, 9 and 12 o'clock positions), Shenting (GV24), Yintang (EX-HN3), and bilateral Shenmen (HT7), Sanyinjiao (SP6), Hegu (LI4) and Taichong (LR3). The true acupuncture was delivered in the spirit regulation group and the sham acupuncture operated in the sham-acupuncture group. One treatment lasted for 30 min, once daily, 5 times a week. The duration of treatment was 3 weeks in the trial. Before treatment and on day 10 and day 21 of treatment, the changes in the score of Hamilton anxiety scale (HAMA) and that of National Institutes of Health Stroke Scale (NIHSS) were compared between the two groups separately. Using ELISA, the contents of adrenocorticotropin (ACTH) and cortisol (CORT) in the serum were detected, and the adverse reactions were recorded. RESULTS: In the within-group comparison before and after treatment, HAMA score and NIHSS score dropped on day 10 and day 21 after treatment in the spirit regulation group (P<0.05)；HAMA score and NIHSS score in the sham-acupuncture group were decreased on day 21 of treatment (P<0.05). After 21 days of treatment, HAMA score and NIHSS score in the spirit-regulation group were decreased significantly than those in the sham-acupuncture group (P<0.05) and the contents of ACTH and CORT in the serum decreased when compared with those before treatment and those of the sham-operation group (P<0.05). No obvious adverse events occurred in the spirit-regulation group and the sham-acupuncture group. CONCLUSIONS: Using sham acupuncture as a control, it is preliminarily confirmed that the spirit regulation method of Jin's three-needle therapy is effective on post-stroke anxiety. In association of the downtrend of serological indicators, it is speculated that the underlying mechanism of this therapy is related to HPA axis.

Sesquiterpenoid derivatives isolated from a liquid culture of Hypholoma capnoides 819.

Nine previously undescribed sesquiterpenoids, named as capnoidones A-G (1-6 and 8) and capnoidols A and B (7 and 9), along with three known sesquiterpenoids, fascicularones A, B, and G (12, 11 and 10), were isolated from the fermentation products of the mushroom Hypholoma capnoides 819 (Strophariace). The structures of these compounds were determined through MS and NMR experiments along with electronic circular dichroism analysis. Optical rotation calculations and X-ray diffraction experiments were also conducted for confirmation of the structures. Compounds 1 and 4 displayed mild cytotoxicity towards BV2 microglial cells in mice, while compound 4 exhibited mild cytotoxicity against breast cancer MCF-7 cells. However, none of the compounds demonstrated antibacterial activity against Staphylococcus aureus or Escherichia coli.

Cardiac and renal outcomes of direct oral anticoagulants in patients with atrial fibrillation.

BACKGROUND: Oral anticoagulation therapy with warfarin or direct oral anticoagulants (DOACs) is the mainstay for stroke prevention in patients with non-valvular atrial fibrillation (AF). The DOACs might have a lower risk of declining renal function than warfarin. This study aimed to compare renal outcomes among rivaroxaban, edoxaban, dabigatran, and warfarin. METHOD: This cohort study identified 2203 adults with AF who started anticoagulation therapy between 1 July 2013 and 31 December 2020, in a clinical database at a single centre. Inverse probability of treatment weighting was adopted to balance baseline characteristics among four anticoagulants treatment groups. The primary outcome was a composite of cardiac and renal outcomes, involving a ≥30% decline in estimated glomerular filtration rate (eGFR), renal failure and cardiovascular death. RESULTS: After propensity score weighting, dabigatran was associated with significantly lower risks of a ≥30% decline in eGFR (hazard ratio [HR]: .69, 95% confidence interval [CI]: .497-.951, p = .0237), doubling of the serum creatinine level (HR: .49, 95% CI: .259-.927, p = .0282) and the cardiac and renal outcome composite (HR: .67, 95% CI: .485-.913, p = .0115) than warfarin. Rivaroxaban and edoxaban did not show significant protective effects on renal outcomes compared to warfarin. CONCLUSION: In this study, patients treated with dabigatran had significantly reduced risks of declining renal function and composite cardiac and renal events than those treated with warfarin. However, rivaroxaban and edoxaban were not associated with lower risks of any renal outcomes than warfarin. More studies are warranted to investigate and compare the impact of renal function between different DOACs in patients with AF.

Concurrence of Insomnia and Daytime Sleepiness Predicted 9-Year Mortality Risk in Community-Dwelling Older Adults: The Yilan Study, Taiwan.

BACKGROUND: Co-occurring insomnia and daytime sleepiness has an undetermined clinical significance in older adults. We aimed to investigate the relationship between various combinations of insomnia and daytime sleepiness with mortality risk in community-dwelling older adults. The moderation effect of sex was also assessed. METHODS: We conducted this follow-up study including community-dwelling adults aged ≥65 in Yilan City, Taiwan. Daytime sleepiness was defined as scoring ≥11 on the Epworth Sleepiness Scale. Insomnia was defined as scores ≥5 on the Athens Insomnia Scale-5. Four phenotypes were defined based on the presence of insomnia or daytime sleepiness. The 9-year mortality risks for various phenotypic combinations were estimated using Cox regression analysis. Sex-specific risks were examined using an interaction term. RESULTS: In total, 2 702 older adults participated in the study, and 59.1% were women. The total 9-year mortality rate was 27.5%. After adjusting for all covariates, compared with those without insomnia or daytime sleepiness, the phenotype of co-occurring insomnia with daytime sleepiness predicted higher mortality risk (hazard ratio [HR]: 1.76, confidence interval [CI]: 1.20-2.58). In contrast, insomnia and daytime sleepiness alone did not correlate with higher mortality. The interaction between sex with co-occurring insomnia and daytime sleepiness was significant (p = .01). When stratifying by sex, the association between co-occurring insomnia and daytime sleepiness with higher mortality risk was male-specific (HR: 3.07, CI: 1.87-5.04). CONCLUSIONS: Concurrence of insomnia and daytime sleepiness indicates a toxic phenotypic combination in older adults, particularly in men. Precise public health and preventive medicine can be implemented through geriatric sleep medicine.

Calculation of the Paternity Index for the Alleged Father Related to the Child's Mother.

OBJECTIVES: To derive the paternity index (PI) calculation formula of the alleged father (AF) when the AF is a relative (parent/child, siblings, grandparent/grandchild, uncle/nephew, first cousins) of the child's biological mother. METHODS: For the case when the AF is related to the child's biological mother, the existence of the relationship in the numerator and denominator hypothesis of PI was considered. The genotype frequency of the AF was calculated by using the frequency formula in which the mother's genotype was considered, while the random male in the denominator was substituted as another relative of the mother's same rank. The PI calculation formula was derived to eliminate the effect of the relationship between AF and the child's biological mother. RESULTS: When the AF and the biological mother have first, second and tertiary kinship, a more conservative PI was obtained from the PI calculation formula derived in this study compared with the PI calculation method which did not consider kinship. CONCLUSIONS: The calculation method provided in this study can eliminate the effect of the relation of the AF and mother on the PI in incest cases, to obtain more accurate and conservative identification conclusions.

Antibiotic synergist OM19r reverses aminoglycoside resistance in multidrug-resistant Escherichia coli.

Introduction: The continued emergence and spread of multidrug-resistant (MDR) bacterial pathogens require a new strategy to improve the efficacy of existing antibiotics. Proline-rich antimicrobial peptides (PrAMPs) could also be used as antibacterial synergists due to their unique mechanism of action. Methods: Utilizing a series of experiments on membrane permeability, In vitro protein synthesis, In vitro transcription and mRNA translation, to further elucidate the synergistic mechanism of OM19r combined with gentamicin. Results: A proline-rich antimicrobial peptide OM19r was identified in this study and its efficacy against Escherichia coli B2 (E. coli B2) was evaluated on multiple aspects. OM19r increased antibacterial activity of gentamicin against multidrug-resistance E. coli B2 by 64 folds, when used in combination with aminoglycoside antibiotics. Mechanistically, OM19r induced change of inner membrane permeability and inhibited translational elongation of protein synthesis by entering to E. coli B2 via intimal transporter SbmA. OM19r also facilitated the accumulation of intracellular reactive oxygen species (ROS). In animal models, OM19r significantly improved the efficacy of gentamicin against E. coli B2. Discussion: Our study reveals that OM19r combined with GEN had a strong synergistic inhibitory effect against multi-drug resistant E. coli B2. OM19r and GEN inhibited translation elongation and initiation, respectively, and ultimately affected the normal protein synthesis of bacteria. These findings provide a potential therapeutic option against multidrug-resistant E. coli.

[Professor ZHUANG Li-xing's experience of mind-regulation acupuncture for psychosomatic disorders].

Professor ZHUANG Li-xing's diagnosis and treatment method and manipulation key points of mind-regulation acupuncture for psychosomatic disorders are summarized. Professor ZHUANG proposes that psychosomatic disorders can be subdivided into "mind-body disorder" and "body-mind disorder". The former requires treatment aimed at regulating the mind. The main acupoints are Sishenzhen, Shenting (GV 24), Yintang (GV 24+), Shenmen (HT 7) and Sanyinjiao (SP 6). The additional acupoints are Suliao (GV 25), Shuigou (GV 26), Shenmai (BL 62), Zhaohai (KI 6), Hegu (LI 4) and Taichong (LR 3), etc. The latter requires treatment aimed at improving the original diseases, supplemented by regulating the mind (row acupuncture on the governor vessel). Acupoint selection is based on the theories of brain-mind, and the emphasis is placed on the governor vessel; in the meanwhile, regulating zangfu and qi-blood should be valued. After the arrival of qi, the Daoqi Tongjing method (the specific technique for directing qi and preserving essence) is applied, combined with auricular point sticking and fire needling at affected part to enhance the curative effect.

Perturbated glucose metabolism augments epithelial cell proinflammatory function in chronic rhinosinusitis.

BACKGROUND: Glucose concentrations are increased in nasal secretions in chronic rhinosinusitis (CRS). However, the glucose metabolism and its contribution to disease pathogenesis in CRS remain unexplored. OBJECTIVES: We sought to explore the glucose metabolism and its effect on the function of nasal epithelial cells in CRS with and without nasal polyps (CRSwNP and CRSsNP). METHODS: Glucose metabolites were detected with mass spectrometry. The mRNA levels of glucose transporters (GLUTs), metabolic enzymes, and inflammatory mediators were detected by quantitative RT-PCR. The protein expression of GLUTs was studied by immunofluorescence staining, Western blotting, and flow cytometry. Glucose uptake was measured by using fluorescent glucose analog. Human nasal epithelial cells (HNECs) were cultured. Bioenergetic analysis was performed with Seahorse XF analyzer. Gene expression in HNECs was profiled by RNA sequencing. RESULTS: Increased glucose concentrations in nasal secretions was confirmed in both CRSsNP and CRSwNP. GLUT4, GLUT10, and GLUT11 were abundantly expressed in HNECs, whose expression was upregulated by inflammatory cytokines and D-glucose and was increased in CRS. Glucose uptake, glycolysis and tricarboxylic acid cycle metabolites, metabolic enzymes, and extracellular acidification rate and oxygen consumption rates were increased in HNECs in CRSsNP and CRSwNP, with a predominant shift to glycolysis. HNECs treated with high-level apical D-glucose showed enhanced glucose uptake, predominant glycolysis, and upregulated production of IL-1α, IL-1ß, TNF-α, CCL20, and CXCL8, which was suppressed by 2-deoxy-D-glucose, an inhibitor of glycolysis. CONCLUSIONS: Increased glucose in nasal secretions promotes glucose uptake and predominant glycolysis in epithelial cells, augmenting the proinflammatory function of epithelial cells in CRS.

Efficacy of acupuncture for the treatment of Parkinson's disease-related constipation (PDC): A randomized controlled trial.

Objective: To evaluate the efficacy of acupuncture in treating Parkinson's disease-related constipation (PDC). Materials and methods: This was a randomized, controlled trial in which patients, outcome assessors, and statisticians were all blinded. Seventy-eight eligible patients were randomly assigned to either the manual acupuncture (MA) or sham acupuncture (SA) groups and received 12 sessions of treatment over a 4-week period. Following treatment, patients were monitored until the eighth week. The primary outcome was the change in weekly complete spontaneous bowel movements (CSBMs) from baseline after treatment and follow-up. The Constipation Symptom and Efficacy Assessment Scale (CSEAS), the Patient-Assessment of Constipation Quality of Life questionnaire (PAC-QOL), and the Unified Parkinson's Disease Rating Scale (UPDRS) were used as secondary outcomes. Results: In the intention-to-treat analysis, 78 patients with PDC were included, with 71 completing the 4-week intervention and 4-week follow-up. When compared to the SA group, weekly CSBMs were significantly increased after treatment with the MA group (P < 0.001). Weekly CSBMs in the MA group were 3.36 [standard deviation (SD) 1.44] at baseline and increased to 4.62 (SD, 1.84) after treatment (week 4). The SA group's weekly CSBMs were 3.10 (SD, 1.45) at baseline and 3.03 (SD, 1.25) after treatment, with no significant change from baseline. The effect on weekly CSBMs improvement in the MA group lasted through the follow-up period (P < 0.001). Conclusion: Acupuncture was found to be effective and safe in treating PDC in this study, and the treatment effect lasted up to 4 weeks.
