Microstructural Changes in the Cerebral White Matter After 12 Months of CPAP Treatment for Moderate to Severe Obstructive Sleep Apnoea: A TBSS Study.

Introduction: Continuous positive airway pressure (CPAP) therapy improves clinical symptoms in patients with obstructive sleep apnea (OSA); however, the mechanism of this clinical improvement and how it may be associated with the restoration of white matter (WM) structures in the brain is unclear. Therefore, this study investigated the relationship between the structural recovery of brain WM and improvements in cognitive function and emotion after long-term (12 months) CPAP treatment in patients with OSA. Methods: We collected data from 17 patients with OSA before and 12 months after CPAP treatment, including sleep monitoring, clinical assessment, and diffusion tensor imaging (DTI) magnetic resonance imaging. Results: We observed a partial reversible recovery of brain WM (mean and radial diffusion coefficients) after treatment. This recovery involved the commissural fibers (cingulum, body of corpus callosum), projection fibers (retrolenticular part of the internal capsule, posterior thalamic radiation, posterior limb of the internal capsule, superior corona radiata, posterior corona radiata), association fibers (external capsule, superior longitudinal fasciculus, inferior longitudinal fasciculus), and other regions. In addition, the improvements in WM fibers in one part of the brain significantly were correlated with the Hamilton Anxiety Scale and Hamilton Depression Scale scores. Discussion: Our results suggest that reversible recovery of reduced brain WM integrity due to OSA may require longer CPAP treatment. Moreover, changes in the integrity of the commissural fibers were associated with emotion regulation. These restored WM areas may explain the cognitive and mood improvements observed after OSA treatment.

Computerized tomography-guided therapeutic percutaneous puncture catheter drainage-combined with somatostatin for severe acute pancreatitis: An analysis of efficacy and safety.

BACKGROUND: Severe acute pancreatitis (SAP), a condition with rapid onset, critical condition and unsatisfactory prognosis, poses a certain threat to human health, warranting optimization of relevant treatment plans to improve treatment efficacy. AIM: To evaluate the efficacy and safety of computerized tomography-guided therapeutic percutaneous puncture catheter drainage (CT-TPPCD) combined with somatostatin (SS) in the treatment of SAP. METHODS: Forty-two SAP patients admitted to The Second Affiliated Hospital of Fujian Medical University from June 2020 to June 2023 were selected. On the basis of routine treatment, 20 patients received SS therapy (control group) and 22 patients were given CT-TPPCD plus SS intervention (research group). The efficacy, safety (pancreatic fistula, intra-abdominal hemorrhage, sepsis, and organ dysfunction syndrome), abdominal bloating and pain relief time, bowel recovery time, hospital stay, inflammatory indicators (C-reactive protein, interleukin-6, and procalcitonin), and Acute Physiology and Chronic Health Evaluation (APACHE) II score of both groups were evaluated for comparison. RESULTS: Compared with the control group, the research group had a markedly higher total effective rate, faster abdominal bloating and pain relief and bowel recovery, shorter hospital length of stay, fewer complications, and lower posttreatment inflammatory indices and APACHE-II scores. CONCLUSION: CT-TPPCD in combination with SS is effective for SAP patients, which can reduce complications, accelerate symptom resolution, inhibit inflammation, and improve patient condition, with promising prospects for clinical promotion.

Diagnostic efficiency of metagenomic next-generation sequencing for suspected spinal tuberculosis in China: A multicenter prospective study.

Background: The pathogens of suspected spinal tuberculosis (TB) include TB and non-TB bacteria. A rapid and effective diagnostic method that can detect TB and non-TB pathogens simultaneously remains lacking. Here, we used metagenomic next-generation sequencing (mNGS) to detect the pathogens in patients with suspected spinal TB. Methods: The enrolled patients with suspected spinal TB were regrouped three times into patients with spinal infection and controls, patients with spinal TB and controls, and patients with non-TB spinal infection and controls. We tested the three groups separately by using mNGS and conventional detection methods. Results: Ultimately, 100 patients were included in this study. Pathogens were detected in 82 patients. Among the 82 patients, 37 had TB and 45 were infected with other bacteria. In patients with spinal infection, the sensitivity of the mNGS assay was higher than that of culture and pathological examination (p < 0.001, p < 0.001). The specificity of the mNGS assay was not statistically different from that of culture and pathological examination (p = 1.000, p = 1.000). In patients with spinal TB, no statistical difference was found between the sensitivity of the mNGS assay and that of Xpert and T-SPOT.TB (p = 1.000, p = 0.430). The sensitivity of the mNGS assay was higher than that of MGIT 960 culture and pathological examination (p < 0.001, p = 0.006). The specificities of the mNGS assay, Xpert, MGIT 960 culture, and pathological examination were all 100%. The specificity of T-SPOT.TB (78.3%) was lower than that of the mNGS assay (100%; p < 0.001). In patients with non-TB spinal infection, the sensitivity of the mNGS assay was higher than that of bacterial culture and pathological examination (p < 0.001, p < 0.001). The specificity of the mNGS assay was not statistically different from that of bacterial culture and pathological examination (p = 1.000, p = 1.000). Conclusion: Data presented here demonstrated that mNGS can detect TB and non-TB bacteria simultaneously, with high sensitivity, specificity and short detection time. Compared with conventional detection methods, mNGS is a more rapid and effective diagnostic tool for suspected spinal TB.

Antiparasitical efficacy of sophoraflavanone G isolated from Sophora flavescens against parasitic protozoa Ichthyophthirius multifiliis.

Ichthyophthirius multifiliis, a global distributed protozoan parasite, causes "White spot disease" and leads to serious mortality of freshwater fish in aquaculture. The present study was conducted to assess the anti-I. multifiliis efficacy of active compound isolated from Sophora flavescens. The isolated active compound was identified as sophoraflavanone G (SG) with ESI-MS and NMR. In vitro tests, SG at concentrations of 0.5 mg/L and 2 mg/L resulted in death of all theronts and tomonts, respectively; SG at concentrations of 0.125 mg/L and 0.25 mg/L notably decreased theronts infectivity (p < 0.05). Additionally, the in vivo test results showed that a cumulative delivery of SG at concentration of 2 mg/L for 7 days protected fish from I. multifiliis infection. The 96-h LC50 (median lethal concentration) and safety concentration of SG to grass carp were 46.6 mg/L and 11.3 mg/L, respectively. The present work indicated that SG was a potential safe and effectively therapeutic agent in treating I. multifiliis.

TM9SF4 Is a Crucial Regulator of Inflammation and ER Stress in Inflammatory Bowel Disease.

BACKGROUND & AIMS: Inflammatory bowel disease (IBD) is a major intestinal disease. Excessive inflammation and increased endoplasmic reticulum (ER) stress are the key events in the development of IBD. Search of a genome-wide association study database identified a remarkable correlation between a TM9SF4 single-nucleotide polymorphism and IBD. Here, we aimed to resolve its underlying mechanism. METHODS: The role of TM9SF4 was determined with experimental mouse models of IBD. ER stress cascades, barrier functions, and macrophage polarization in colonic tissues and cells were assessed in vivo and in vitro. The expression of TM9SF4 was compared between inflamed regions of ulcerative colitis patients and normal colon samples. RESULTS: In mouse models of IBD, genetic knockout of the TM9SF4 gene aggravated the disease symptoms. In colonic epithelial cells, short hairpin RNA-mediated knockdown of TM9SF4 expression promoted inflammation and increased ER stress. In macrophages, TM9SF4 knockdown promoted M1 macrophage polarization but suppressed M2 macrophage polarization. Genetic knockout/knockdown of TM9SF4 also disrupted epithelial barrier function. Mechanistically, TM9SF4 deficiency may act through Ca2+ store depletion and cytosolic acidification to induce an ER stress increase. Furthermore, the expression level of TM9SF4 was found to be much lower in the inflamed colon regions of human ulcerative colitis patients than in normal colon samples. CONCLUSIONS: Our study identified a novel IBD-associated protein, TM9SF4, the reduced expression of which can aggravate intestinal inflammation. Deficiency of TM9SF4 increases ER stress, promotes inflammation, and impairs the intestinal epithelial barrier to aggravate IBD.

Effects of can walking anterior and posterior capsule polishing combined with tension ring implantation on lens capsular stability after phacoemulsification for ultra-high myopia cataract / 中华显微外科杂志

Objective:To observe the effects of polishing the anterior and posterior capsule with irrigation/aspiration (I/A) injection needle and capsular tension ring (CTR) implantation on intraocular lens (IOL) capsular stability after phacoemulsification for ultra-high myopia with 2.0 mm coaxial micro incision.Methods:This is a prospective randomized controlled study. There were 40 patients(80 eyes) aged 46-72 years old with ultra-high myopia cataract. The grade of lens opacity was grade II-IV, and the diopter was -10 D - -24 D. During 2.0 mm coaxial micro incision phacoemulsification, adopt coin tossing method randomly, 1 eye was operated using the anterior and posterior capsule polishing 360° with I/A injection needle combined with CTR implantation as the experimental group(40 eyes), the other eye was neither polished nor CTR implantated as the control group(40 eyes). The operation interval of both eyes was less than 1 week. The size of anterior capsular orifice, effective intraocular lens position(ELP), IOL eccentricity and posterior capsular opacification(PCO) were recorded at 1 week, 1, 3 and 6 months after operation in outpatient clinic. Two independent sample t-test and Fisher exact probability test were used to compare the differences between the 2 groups. P<0.05 was defined significant difference. Results:During the follow-up period, there were no significant change in the anterior capsule area, IOL eccentricity and ELP in the experimental group. However in the control group, the anterior capsular area decreased gradually with time, and gradually IOL eccentricity increased and ELP decreased. There was no significant difference between the 2 groups in each observation index at 1 week after operation, but it was ELP that first showed the difference tendency( P<0.01). The ELP of the control group was significantly lower than that of the experimental group at 1, 3 and 6 months after operation( P<0.05). There was no significant difference in anterior capsule area and IOL eccentricity between the 2 groups at 1 and 3 months after operation( P>0.05), but there was a significant difference at 6 months( P<0.05). In terms of PCO, the incidence of PCO was 0%, 2.5% and 7.5% in the experimental group and 5.0%, 17.5% and 32.5% in the control group respectively at 1, 3 and 6 months after operation. The incidence of PCO in the experimental group was significantly lower than that in the control group( P<0.05). Conclusion:Ultra-high myopia with cataract are prone to have capsular contraction after operation, which is characterized by IOL instability and anterior capsular orifice narrowing gradually. Combined 360° anterior and posterior capsular polishing with tension ring implantation in operation can effectively maintain the stability of ELP, reduce the degree of contraction of anterior capsular orifice, reduce the eccentricity of IOL and the incidence of PCO. Polishing the anterior and posterior capsule with I/A injection needle combined with CTR implantation, is safe and effective for patients with ultra-high myopia cataract.

Antiparasitic Efficacy of Crude Plant Extracts and Compounds Purified from Plants against the Fish Monogenean Neobenedenia girellae.

Neobenedenia girellae is a pathogenic ectoparasite of many marine fishes, and it causes major epidemics in marine aquaculture. In this study, the efficacy of ethanol extracts of huangqi Astragalus membranaceus (known as milkvetch in North America), guanzhong Dryopteris setosa (known as beaded wood fern in North America), gancao Glycyrrhiza uralensis (known as Chinese licorice in North America), danshen Salvia miltiorrhiza (known as red sage in North America), and pomegranate Punica granatum, as well as seven phytochemicals (10-gingerol, curcumin, cynatratoside-C, emodin, kuwanon-G, kuwanon-O, and sophoraflavanone-G), against adult N. girellae was investigated. In vitro results indicated that pomegranate extract killed all adult N. girellae at a 62.5-mg/L concentration with an 8-h exposure, but gancao extract did not cause 100% mortality until a 1,000-mg/L concentration was used. Additionally, all adult N. girellae died after an 8-h exposure to cynatratoside-C, kuwanon-G, kuwanon-O, or sophoraflavanone-G at a concentration of 125 mg/L. Curcumin, emodin, and 10-gingerol at a concentration of 1,000 mg/L did not kill all parasites after an 8-h exposure. These findings demonstrate that plant extracts and active phytochemicals are potential sources of botanical drugs for controlling N. girellae infection in aquaculture.

Effects of Enriched Environment on Neurological Function and Glucose Metabolism in Ischemic Penumbra in Cerebral Ischemia-reperfusion Injury Rats / 中国康复理论与实践

Objective:To explore the effects of enriched environment on neurological function in cerebral ischemia-reperfusion injury rats and the glucose metabolism in ischemic penumbra. Methods:A total of 72 adult male Sprague-Dawley rats were randomly divided into sham group (n = 24), model group (n = 24) and enriched environment group (n = 24). The latter two groups suffered cerebral ischemia 60 minutes and reperfused with modified Longa's method. The enriched environment group was fed in enriched environment after operation. All the rats were assessed with modified Neurological Severity Score (mNSS) before, and one, seven, 14, 21 and 28 days after operation. One and 28 days after operation, twelve rats from each groups were sacrificed after mNSS assessment, respectively. The histopathology was observed with HE staining. The expressions of hypoxia-inducible factor-1α (HIF-1α), glucose transporter 1 (GLUT1) and 6-phosphofructo-2-kinase/fructose-2-bisphosphatase 3 (PFKFB3) in ischemic penumbra were determined with reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR) and Western blotting. The levels of ATP, ADP and AMP in ischemic penumbra were measured with high performance liquid chromatography (HPLC) and the energy charge (EC) was calculated. Results:Compared with the model group, the scores of mNSS decreased in the enriched environment group since 14 days after operation (P < 0.05). The cells in the penumbra presented edema, nuclear pyknosis marginalization, vacuolar arrangement and other pathological changes in the model group and the riched environment group one day after operation; while compared with the model group, the levels of ATP and EC decreased and the mRNAs and protein expression of HIF-1α, GLUT1 and PFKFB3 increased in the enriched environment group (P < 0.05). The pathology improved in the riched environment group compared with that in the model group 28 days after operation; while the mRNAs and protein expression of HIF-1α, GLUT1 and PFKFB3 increased, as well as the levels of ATP and EC (P < 0.05). Conclusion:Enriched environment can promote the recovery of neurological function in rats after cerebral ischemia-reperfusion, which may associate with promoting expression of HIF-1α and downstream GLUT1 and PFKFB3, and improving glucose metabolism.

[Research advances in model simulation and data assimilation of water and carbon fluxes in land surface vegetation].

Accurately estimating water and carbon fluxes is of great significance for the research in land surface water and carbon cycles. However, it is very challenging. The estimation accuracy needs further improvement. Both traditional model simulation and site observation methods have advantages and disadvantages, which need to be examined in combination. Data assimilation integrates observations into models based on physics laws to obtain the optimal estimates of model state variables and parameters as much as possible, and provides an effective way for their combination. In this review, we traced the research progress for process models assimilated with multi-source observational data of land surface water carbon fluxes and analyzed the domestic and foreign research status of land surface process models focused on water carbon fluxes, data assimilation algorithms, and assimilation of land surface carbon flux data. We summaried problems in this research area, including insufficient coordination of multi-source observation data, relatively simple assimilation strategy, lacking fusion of assimilation models, and limited assimilation scale. The future development directions and trends were analyzed and prospected from five aspects, including assimilation strategy, model selection, data expansion, scale effect, and scientific calculation. This work would provide more comprehensive background information for scholars in this field, and arouse common concerns.

Efficacy and antiparasitic mechanism of 10-gingerol isolated from ginger Zingiber officinale against Ichthyophthirius multifiliis in grass carp.

Ichthyophthirius multifiliis is a ciliate parasite of freshwater fish with a global distribution and results in severe economic losses in aquaculture. The present study aimed to investigate the efficacy and antiparasitic mechanism of active compounds isolated from Zingiber officinale against I. multifiliis. Three compounds were isolated from the Z. officinale extract and identified as 10-gingerol, 6-dehydroshogaol, and 6-dehydro-10-gingerol. 10-gingerol demonstrated the greatest antiparasitic efficacy in vitro. 10-gingerol resulted in 100% mortalities of theronts, nonencysted tomonts, and encysted tomonts at concentrations of 2, 8, and 16 mg/L, respectively. 10-gingerol significantly reduced theronts infectivity (p < 0.05) at a concentration of 1 mg/L, and it was effective in treating infected grass carp and protecting naïve fish from I. multifiliis infestation at a concentration of 4 mg/L. The antiparasitic mechanism might be attributed to the increase of intracellular osmotic pressure, accumulation of free radicals, and membrane damage of I. multifiliis post 10-gingerol treatment. The study demonstrated that 10-gingerol had the potential as a therapeutic agent against I. multifiliis.

Molecular characterization, expression analysis, and ontogeny of complement component C9 in southern catfish (Silurus meridionalis).

The complement system plays an important role in host defense against invading microorganisms. Complement component C9 is the last component that is involved in the formation of the membrane attack complex (MAC) on the surface of target cells. In the present study, the full length C9 cDNA sequence of 1984 bp with an open reading frame (ORF) of 1809 bp was cloned from southern catfish (Silurus meridionalis). The deduced amino acid sequence showed similarity with other teleost fish. The mRNA expression of C9 was detected in the liver, spleen, stomach, intestine, and head kidney, with highest levels detected in the liver. The mRNA of C9 was first detected in the yolk syncytial layer at 34 h post fertilization (hpf) with whole mount in situ hybridization, followed by the liver at 36 h post hatching (hph). The mRNA expression of C9 was upregulated significantly in the liver, spleen, and intestine following the injection with Aeromonas hydrophila, suggesting that C9 played an important role in defense against invading pathogens in southern catfish. Therefore, these results provide important information to understand the functions of C9 during fish early development in fish.

The variation of neutrophil extracellular traps in the staphylococcus aureus infected MRL/lpr systemic lupus erythematosus mouse / 中华风湿病学杂志

Objective This study aims to investigate the variation of neutrophil extracellular traps (NETs) in animal model of staphylococcus aureus (SA) infected systemic lupus erythematosus (SLE) MRL/Lpr mouse.Methods The infection model was developed by injecting the Staphylococcus Aureus in the mouse tail vein.The Staphylococcus Aureus load of the serum and kidney was detected by enzyme-linked immuno sorbent assay (ELISA).The level of NETs complex in the serum was detected by Cell-Death-Elisa-Plus-Kit and anti-myeloperoxidase (MPO) antibody.The kidney NETs formation was tested with the immunofluorescence.Statistical program for social sciences (SPSS) 17.0 software and Image Pro Plus statistical software were used for analysis.Comparisons between groups were made using unpaired t test for normally distributed numerical data,nonparametric test for non-normally distributed numerical data,and single factor analysis (ANOVA) for variance.Results The incidence of walking instability,purulent exudate in eyes and death was 2/6,1/6,1/6 respectively in Staphylococcus Aureus-infected MRL/Lpr mice,However,The control group had no death and related symptoms.The Staphylococcus Aureus load of the serum was higher in MRl/lpr mice when compared to the control group [(106.79±23.39) ng/ml vs (48.82±11.49) ng/ml,U=2.739,P＜0.05] after Staphylococcus Aureus infection.The control group had a higher NETs level [(2.24±0.15) vs (1.64±0.08),U=2.882,P＜0.05],however,all the MRL/Lpr mice had no significant change of the NETs level [(2.63±0.61) vs (2.65 ±0.260),U=0.548,P＞0.05] after Staphylococcus Aureus infection.Conclusion After infected by the Staphylococcus Aureus,more symptoms,higher death rate and higher Staphylococcus Aureus load of the serum present in the MRlL/lpr mice than the control group.While,there's none significant change of the NETs level in Staphylococcus Aureus-infected MRLL/lpr mice.This suggests that the dyspoiesis of NETs is present in Staphylococcus Aureus-infected MRL/lpr mice.

[Temporal and spatial heterogeneity analysis of optimal value of sensitive parameters in ecological process model: The BIOME-BGC model as an example.] / 生态过程模型敏感参数最优取值的时空异质性分析­­ä»¥BIOME-BGC模型为例.

The ecological process models are powerful tools for studying terrestrial ecosystem water and carbon cycle at present. However, there are many parameters for these models, and weather the reasonable values of these parameters were taken, have important impact on the models simulation results. In the past, the sensitivity and the optimization of model parameters were analyzed and discussed in many researches. But the temporal and spatial heterogeneity of the optimal parameters is less concerned. In this paper, the BIOME-BGC model was used as an example. In the evergreen broad-leaved forest, deciduous broad-leaved forest and C3 grassland, the sensitive parameters of the model were selected by constructing the sensitivity judgment index with two experimental sites selected under each vegetation type. The objective function was constructed by using the simulated annealing algorithm combined with the flux data to obtain the monthly optimal values of the sensitive parameters at each site. Then we constructed the temporal heterogeneity judgment index, the spatial heterogeneity judgment index and the temporal and spatial heterogeneity judgment index to quantitatively analyze the temporal and spatial heterogeneity of the optimal values of the model sensitive parameters. The results showed that the sensitivity of BIOME-BGC model parameters was different under different vegetation types, but the selected sensitive parameters were mostly consistent. The optimal values of the sensitive parameters of BIOME-BGC model mostly presented time-space heterogeneity to different degrees which varied with vegetation types. The sensitive parameters related to vegetation physiology and ecology had relatively little temporal and spatial heterogeneity while those related to environment and phenology had generally larger temporal and spatial heterogeneity. In addition, the temporal heterogeneity of the optimal values of the model sensitive parameters showed a significant linear correlation with the spatial heterogeneity under the three vegetation types. According to the temporal and spatial heterogeneity of the optimal values, the parameters of the BIOME-BGC model could be classified in order to adopt different parameter strategies in practical application. The conclusion could help to deeply understand the parameters and the optimal values of the ecological process models, and provide a way or reference for obtaining the reasonable values of parameters in models application.
