RESUMO

Taste is a critical sensory function for human as it supports sustenance and alerts the body to toxins. Taste dysfunction is a common side effect of radiotherapy for the head and neck cancers, which is often accompanied by oral mucositis in the early stage. It is associated with anorexia, anxiety and depression, leading to declined quality of life and treatment tolerance. The incidence of radiation-induced taste dysfunction is high, and its clinical manifestations include increased taste threshold, tastelessness, and persistent bitter, sour or metallic taste, which exert significant effect upon the quality of life. At present, effective therapeutic measures for radiation-induced taste dysfunction are still lacking. In this article, research progresses on clinical characteristics and the potential mechanisms of radiation-induced taste dysfunction were reviewed, aiming to provide reference for the mechanism, prevention and treatment for taste dysfunction.

The patients were divided into dexmedetomidine combined with sufentanil group (S group) and dexmedetomidine combined with oxycodone group (Q group) by random digits table method with 40 cases each group. On the basis of routine monitoring and treatment after operation, the patients in Q group were continuously injected with oxycodone 0.03 mg/(kg·h) and dexmedetomidine 0.4 μg/(kg·h) through analgesia pump, the patients in S group were continuously injected with sufentanil 0.03 mg/(kg·h) and dexmedetomidine 0.4 μg/(kg·h) through analgesia pump. The wake-up time, extubation time, awakening quality (Aldrete score and bucking score) and comfort level (Bruggrmann comfort scale score, BCS score) after entering the AICU were record; the sedation score (Ramsay score) and pain relief score (numerical rating scale score, NRS score) and hemodynamic changes (mean arterial pressure and heart rate) 3, 5, 7, 10 and 14 h after entering the AICU were record; the level of serum inflammatory factors, including tumor necrosis factor (TNF-α), interleukin-6 (IL-6) and C-reactive protein (CRP) immediately, 5 h and 14 h after entering the AICU; press times of analgesia pump, adverse events, bleeding volume of drainage tube during AICU and overall satisfaction score when leaving the AICU were record.Results:The bucking score in Q group was significantly lower than that in S group: (1.02 ± 0.77) scores vs. (1.88 ± 0.34) scores, the Aldrete score and BCS score were significantly higher than those in S group: (8.93 ± 0.25) scores vs. (5.97 ± 0.32) scores and (3.03 ± 0.32) scores vs. (0.93 ± 0.52) scores, and there were statistical differences ( P<0.01); there were no statistical difference in wake-up time and extubation time between two groups ( P>0.05). There were no statistical difference Ramassy score, NRS score 3 and 5 h after entering the AICU, mean arterial pressure and heart rate between two groups ( P>0.05); the Ramassy score 7, 10 and 14 h after entering the AICU in Q group was significantly lower than that in S group, the NRS score, mean arterial pressure and heart rate were significantly lower than those in S group, and there were statistical differences ( P<0.01). There were no statistical differences in TNF-α, IL-6 and CRP immediately after entering the AICU between two groups ( P>0.05); the TNF-α, IL-6 and CRP 5 and 14 h after entering the AICU in Q group were significantly lower than those in S group, and there were statistical difference ( P<0.01). The press times of analgesia pump, bleeding volume of drainage tube and the incidences of nausea vomiting, respiratory depression, lethargy, restlessness, fever and lung infection in Q group were significantly lower than those in S group: (4.63 ± 1.10) times vs. (18.80 ± 1.54) times, (129.67 ± 4.14) ml vs. (164.00 ± 8.14) ml, 10.0% (4/40) vs. 52.5% (21/40), 2.5% (1/40) vs. 25.0% (10/40), 7.5% (3/40) vs. 47.5% (19/40), 0 vs. 20.0% (8/40), 2.5% (1/40) vs. 22.5% (9/40) and 2.5% (1/40) vs. 20.0% (8/40), and there were statistical differences ( P<0.01 or <0.05); there was no severe hypotension, severe bradycardia and delirium in both groups. The overall satisfaction score in Q group was significantly higher than that in S group: (3.53 ± 0.63) scores vs. (2.70 ± 0.65) scores, and there was statistical difference ( P<0.01). Conclusions:Continuous micro-pump infusion of dexmedetomidine combined with oxycodone in AICU elderly patients with lung cancer after thoracoscopic radical surgery can significantly improve the quality of recovery and comfort during extubation, without affecting the extubation time, and can effectively reduce the degree of pain, stress and inflammatory reaction in the early recovery period, and reduce the incidence of adverse events after surgery.

RESUMO

Objective:To evaluate the protective effect of foam dressing in preventing intraoperative acquired pressure injury (IAPI), and to provide reference basis for prevention and treatment of IAPI during clinical operation.Methods:The clinical data of 455 surgical patients admitted to Xinhua Hospital Affiliated to Shanghai Jiao Tong University from October 2020 to January 2021 were retrospectively collected. According to whether foam dressing was used at the compression site during operation, the patients were divided into dressing group (101 cases) and control group (354 cases). The two groups were matched with age, body mass index, preoperative Braden and cerebrovascular disease as covariates, and were finally divided into 89 patients in the dressing group and 162 patients in the control group. Logistic regression analysis and stratified analysis were used to comprehensively evaluate the actual effect of foam dressing on the occurrence of IAPI in the surgical patients.Results:Among the 251 patients, there were 14 (15.7%) cases with IAPI in the dressing group and 13 (8.0%) cases in the control group, and the difference was not statistically significant ( χ2=3.41, P>0.05). Among the patients in the prone position, compared to the control group, the dressing group can effectively reduce the risk of IAPI in surgical patients by 77% ( OR=0.23, 95% CI 0.05-0.98, P<0.05). There was no interaction between foam dressing and intraoperative surgical characteristics ( P>0.05). Conclusions:Foam dressing plays a protective role in preventing the occurrence of IAPI in patients undergoing surgery in the prone position. There was no significant protective effect of intraoperative foam dressing in patients with other surgical characteristics.

RESUMO

OBJECTIVE@#To analyze the effect of mechanical cardiopulmonary resuscitation (CPR) on patients with cardiac arrest with the vertical spatial pre-hospital emergency transport.@*METHODS@#A retrospective cohort study was conducted. The clinical data of 102 patients with out-of-hospital cardiac arrest (OHCA) who were transferred to the emergency medicine department of Huzhou Central Hospital from the Huzhou Emergency Center from July 2019 to June 2021 were collected. Among them, the patients who performed artificial chest compression during the pre-hospital transfer from July 2019 to June 2020 served as the control group, and the patients who performed artificial-mechanical chest compression (implemented artificial chest compression first, and implemented mechanical chest compression immediately after the mechanical chest compression device was ready) during pre-hospital transfer from July 2020 to June 2021 served as the observation group. The clinical data of patients of the two groups were collected, including basic data (gender, age, etc.), pre-hospital emergency process evaluation indicators [chest compression fraction (CCF), total CPR pause time, pre-hospital transfer time, vertical spatial transfer time], and in-hospital advanced resuscitation effect evaluation indicators [initial end-expiratory partial pressure of carbon dioxide (PETCO2), rate of restoration of spontaneous circulation (ROSC), time of ROSC].@*RESULTS@#Finally, a total of 84 patients were enrolled, including 46 patients in the control group and 38 in the observation group. There was no significant difference in gender, age, whether to accept bystander resuscitation or not, initial cardiac rhythm, time-consuming pre-hospital emergency response, floor location at the time of onset, estimated vertical height, and whether there was any vertical transfer elevator/escalator, etc. between the two groups. In the evaluation of the pre-hospital emergency process, the CCF during the pre-hospital emergency treatment of patients in the observation group was significantly higher than that in the control group [69.05% (67.35%, 71.73%) vs. 61.88% (58.18%, 65.04%), P < 0.01], the total pause time of CPR was significantly shorter than that in the control group [s: 266 (214, 307) vs. 332 (257, 374), P < 0.05]. However, there was no significant difference in the pre-hospital transfer time and vertical spatial transfer time between the observation group and the control group [pre-hospital transfer time (minutes): 14.50 (12.00, 16.75) vs. 14.00 (11.00, 16.00), vertical spatial transfer time (s): 32.15±17.43 vs. 27.96±18.67, both P > 0.05]. It indicated that mechanical CPR could improve the CPR quality in the process of pre-hospital first aid, and did not affect the transfer of patients by pre-hospital emergency medical personnel. In the evaluation of the in-hospital advanced resuscitation effect, the initial PETCO2 of the patients in the observation group was significantly higher than that of the patients in the control group [mmHg (1 mmHg ≈ 0.133 kPa): 15.00 (13.25, 16.00) vs. 12.00 (11.00, 13.00), P < 0.01], the time of ROSC was significantly shorter than that in the control group (minutes: 11.00±3.25 vs. 16.64±2.54, P < 0.01), and the rate of ROSC was slightly higher than that in the control group (31.58% vs. 23.91%, P > 0.05). It indicated that continuous mechanical compression during pre-hospital transfer helped to ensure continuous high-quality CPR.@*CONCLUSIONS@#Mechanical chest compression can improve the quality of continuous CPR during the pre-hospital transfer of patients with OHCA, and improve the initial resuscitation outcome of patients.

RESUMO

Objective: To investigate the poisonous substances and geographical distribution of poisoning in children in China. Methods: A cross-sectional study. The clinical data of 8 385 hospitalized children from January 2016 to December 2020 were extracted from the FUTang Updating Medical Records database. These children aged 0 to 18 years and were admitted due to poisoning. They were grouped according to age (newborns and infants, toddlers, preschoolers, school-age children, adolescents), place of residence (Northeast China, North China, Central China, East China, South China, Southwest China, Northwest China), and mode of discharge (discharge under medical advice, transfer to another hospital under medical advice, discharge without medical advice, death, other). The poisonous substance and causes of poisoning in different groups were analyzed. Results: Among these 8 385 children, 4 734 (56.5%) were male and 3 651 (43.5%) female, with a male-to-female ratio of 1.3∶1. The age was 3 (2, 7) years. The prevalence of poisoning was 51.8% (4 343/8 385) in toddlers, 16.5% (1 380/8 385) in adolescents, 14.8% (1 242/8 385) in preschoolers, 14.4% (1 206/8 385) in school-age children, and 2.5% (214/8 385) in newborns and infants. Drug poisoning accounted for 43.5% (3 649/8 385) and pesticide accounted for 26.8% (2 249/8 385). Drug poisoning was more common in adolescents (684/1 380, 49.6%) and toddlers (2 041/4 343, 47.0%); non-drug poisoning was more common in school-age children (891/1 206, 73.9%), of which carbon monoxide was mainly in newborns and infants (41/214, 19.2%) and food poisoning in children of school age (241/1 206, 20.0%). Regarding regional characteristics, drug poisoning was more frequent in South China (188/246, 64.2%) and non-drug poisoning was more frequent in Southwest China (815/1 123, 72.5%). For drugs, anti-epileptic drugs, sedative-hypnotic drugs and anti-Parkinson's disease drugs had a higher proportion of poisoning in North China (138/1 034, 13.0%) than that in other regions. For non-drug poisoning, pesticides (375/1 123, 33.3%), food poisoning (209/1 123, 18.6%) and contact with poisonous animals (86/1 123, 7.7%) were more common in Southwest China than in other regions; carbon monoxide poisoning was more common in North China (81/1 034, 7.6%) and Northwest China (65/1 064, 6.3%). In Central China, poisoning happened more in toddlers (792/1 295, 61.2%) and less in adolescents (115/1 295, 8.8%) than in other regions. Regarding different age groups, poisoning in adolescent happened more in Northeast China (121/457, 26.5%), North China (240/1 034, 23.2%), and Northwest China (245/1 064, 23.0%). The rate of discharge under medical advice, discharge without medical advice, and mortality rate within the 5 years were 77.0% (6 458/8 385), 20.8% (1 743/8 385), 0.5% (40/8 385), respectively. Conclusions: Poisoning is more common in male and toddlers. Poisonous substances show a regional characteristic and vary in different age groups, with drugs and insecticides as the most common substances.

RESUMO

Irinotecan is an anticancer topoisomerase I inhibitor that acts as a prodrug of the active metabolite, SN-38. Unfortunately, the limited utility of irinotecan is attributed to its pH-dependent stability, short half-life and dose-limiting toxicity. To address this problem, a novel trivalent PEGylated prodrug (PEG-[Irinotecan]3) has been synthesized and its full-profile pharmacokinetics, antitumor activity and toxicity compared with those of irinotecan. The results show that after intravenous administration to rats, PEG-[Irinotecan]3 undergoes stepwise loss of irinotecan to form PEG-[Irinotecan]3‒x (x = 1,2) and PEG-[linker] during which time the released irinotecan undergoes conversion to SN-38. As compared with conventional irinotecan, PEG-[Irinotecan]3 displays extended release of irinotecan and efficient formation of SN-38 with significantly improved AUC and half-life. In a colorectal cancer-bearing model in nude mice, the tumor concentrations of irinotecan and SN-38 produced by PEG-[Irinotecan]3 were respectively 86.2 and 2293 times higher at 48 h than produced by irinotecan. In summary, PEG-[Irinotecan]3 displays superior pharmacokinetic characteristics and antitumor activity with lower toxicity than irinotecan. This supports the view that PEG-[Irinotecan]3 is a superior anticancer drug to irinotecan and it has entered the phase II trial stage.

RESUMO

【Objective】 To effectively differentiate adrenal adenoma (AA) and small diameter pheochromocytoma (PCC) by establishing a clinical-radiomic nomogram model before surgery. 【Methods】 A total of 132 pathologically confirmed patients (45 PCC cases, 87 AA cases) were enrolled. After the features of enhanced CT were assessed, the radiomic features and related clinical indicators were extracted. Based on multiple Logistic regression, a clinical-radiomic nomogram with radiomic features and independent clinical predictors was developed. The area under the receiver operating characteristic (ROC) curve (AUC) was used for internal evaluation to compare the diagnostic effectiveness of the three models. The clinical effectiveness of the nomogram was verified with decision curve analysis (DCA). 【Results】 One of the 108 candidate features was used to construct the radiological feature score. Individualized clinical-radiomic nomogram included independent clinical factors (24 h urinary vanmandelic acid/renin/angiotensin I) and original first-order median radiological feature scores. Internal evaluation of the prediction model showed that the AUC was 0.945 (95%CI:0.906-0.984), superior to the single clinical model or radiological model in precise differentiation. DCA showed that the nomogram had the best clinical use. 【Conclusion】 The clinical-radiomic nomogram model can effectively differentiate adrenal adenoma from small diameter pheochromocytoma, which can improve the preoperative differential diagnosis and preparation.

RESUMO

【Objective】 To investigate the predictive value of preoperative controlled nutritional status (CONUT) score and ratio of hemoglobin to red cell distribution width (HRR) for survival of patients with upper urinary tract urothelial carcinoma (UTUC) after radical surgery. 【Methods】 A retrospective analysis was performed on 145 UTUC patients who underwent surgical treatment in the Affiliated Hospital of Xuzhou Medical University during May 2011 and Jun. 2017. Clinic opathologic data were collected, the best cut-off values of CONUT score and HRR were determined with receiver operating characteristic (ROC) curve, and the CONUT-HRR scoring system was established. The correlation between different CONUT-HRR scores and clinic opathological indicators of UTUC patients was compared. The application value of CONUT-HRR score in predicting the prognosis of UTUC patients was evaluated with Kaplan-Meier survival curve and Cox proportional risk regression model. 【Results】 The optimal cut-off values of preoperative CONUT score and HRR for predicting cancer specific survival (CSS) were 3 and 10.41, respectively. The patients were divided into three groups: CONUT-HRR 0 group (n=62, CONUT score <3 and HRR ≥10.41), CONUT-HRR 1 group (n=51, CONUT score <3 and HRR <10.41, or CONUT score ≥3 and HRR≥10.41), and CONUT-HRR 2 group (n=32, CONUT score ≥3 and HRR <10.41). CONUT-HRR score was correlated with age, surgical method, pathological T stage, lymph node metastasis and vascular invasion (all P<0.05). Kaplan-Meier survival curve results showed that the 5-year CSS of CONUT-HRR 0, 1 and 2 groups were 96.4%, 65.8% and 30.9%, respectively, with statistically significant differences (P<0.001). Cox regression model showed that CONUT-HRR score, pathological T stage, lymph node metastasis and vascular infiltration were independent factors of CSS. 【Conclusion】 Preoperative CONUT-HRR score can be used as a simple and reliable indicator to evaluate the prognosis of UTUC patients. Higher score indicates worse prognosis.

RESUMO

【Objective】 To analyze the efficacy and safety of intralesional triamcinolone acetonide in the treatment of mass granulomatous mastitis (GLM). 【Methods】 Retrospective analysis was made on 67 patients with GLM who were treated in Xijing Hospital from July 2021 to May 2022 and met the inclusion criteria. Among them, 31 patients were treated with local injection of triamcinolone acetonide, while 36 ones were treated with oral methylprednisolone. All the included patients underwent surgical treatment after their condition met the surgical criteria, and the follow-up period lasted for up to six months after surgery. The two groups were compared in improvement of symptoms and signs, treatment time, clinical effectiveness and safety, and recurrence rate. 【Results】 The effective rate of triamcinolone acetonide group and methylprednisolone group was 100%, but the clinical cure rate was significantly higher in triamcinolone acetonide group than in methylprednisolone group in stratified analysis (P<0.05). The improvement time of symptoms and signs in triamcinolone acetonide group was significantly shorter than that in methylprednisolone group (P<0.05). The incidence of side effects in triamcinolone acetonide group was also significantly reduced compared to methylprednisolone group (P<0.05). Follow-up for half a year showed no recurrence in both groups. 【Conclusion】 Compared with the traditional oral methylprednisolone group, local injection of triamcinolone acetonide in the treatment of mass granulomatous mastitis can rapidly relieve clinical symptoms and signs, shorten treatment time, and has higher efficiency and fewer side effects. Local injection of hormone combined with surgery is effective in treating mass granulomatous mastitis with low recurrence rate.

RESUMO

Due to long-term use of immunosuppressive agents, solid organ transplant recipients (SOTR) belong to high-risk populations of multiple pathogenic infection, including SARS-CoV-2. In addition, SOTR are constantly complicated by chronic diseases, such as hypertension and diabetes mellitus, etc. After infected with SARS-CoV-2, the critically ill rate and fatality of SOTR are higher than those of the general population, which captivates widespread attention from experts in the field of organ transplantation. Omicrone variant is currently the significant pandemic strain worldwide, rapidly spreading to more than 100 countries worldwide and causing broad concern. According to the latest international guidelines on the diagnosis and treatment of SARS-CoV-2 infection and relevant expert consensus in China combined with current domestic situation of SARS-CoV-2 pandemic and China's "diagnosis and treatment regimen for SARS-CoV-2 infection (Trial Version 10)", the epidemiology, clinical manifestations and prognosis, diagnosis, clinical classification and treatment of SARS-CoV-2 infection were briefly reviewed.

RESUMO

This study aimed to evaluate the efficacy and safety of various oral Chinese patent medicines in the adjuvant treatment of rotavirus gastroenteritis(RVGE) in children based on network Meta-analysis. Randomized controlled trial(RCT) of oral Chinese patent medicine in the adjuvant treatment of RVGE in children was retrieved from the databases such as CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library, EMbase, and Web of Science from database inception to October 22, 2022. The quality of the included RCT was evaluated according to the Cochrane risk-of-bias tool, and the data were analyzed by RevMan 5.4 and Stata 16 software. Sixty-three RCTs were included, with 11 oral Chinese patent medicines involved, including Xingpi Yanger Granules, Weichang'an Pills, Qiuxieling Mixture, Erxieting Granules, and Changyanning Granules/Syrup. The results of the network Meta-analysis showed that in terms of clinical total effective rate, the top 3 optimal interventions were Changyanning Granules/Syrup, Xiaoer Guangpo Zhixie Oral Liquid, and Xiaoer Shuangjie Zhixie Granules combined with conventional western medicine. In terms of the anti-diarrheal time, the top 3 optimal interventions were Shenling Baizhu Granules, Qiuxieling Mixture, and Shuangling Zhixie Oral Liquid combined with conventional western medicine. In terms of the antiemetic time, the top 3 optimal interventions were Changyanning Granules/Syrup, Xingpi Yanger Granules, and Xiaoer Shuangjie Zhixie Granules combined with conventional western medicine. In terms of the antipyretic time, the top 3 optimal interventions were Shenling Baizhu Granules, Xiaoer Shuangjie Zhixie Granules, and Qiuxieling Mixture combined with conventional western medicine. In terms of the negative conversion rate of rotavirus, the top 3 optimal interventions were Xingpi Yanger Granules, Erxieting Granules, and Cangling Zhixie Oral Liquid combined with conventional western medicine. In terms of reducing creatine kinase isoenzyme MB(CK-MB) level, the top 3 optimal interventions were Weichang'an Pills, Xingpi Yanger Granules, and Xiaoer Shuangjie Zhixie Granules combined with conventional western medicine. In terms of adverse reactions, no se-rious adverse reactions were reported in all studies. Oral Chinese patent medicines in the adjuvant treatment of children with RVGE have their own advantages, Specifically, Changyanning Granules/Syrup + conventional western medicine focuses on improving the clinical total effective rate and shortening the antiemetic time, Shenling Baizhu Granules + conventional western medicine on shortening the anti-diarrheal time and antipyretic time, Xingpi Yanger Granules + conventional western medicine on improving the negative conversion rate of rotavirus, and Weichang'an Pills + conventional western medicine on reducing the CK-MB level. Limited by the quantity and quality of literature included in this study, the results need to be verified by high-quality RCT with a larger sample size.

RESUMO

This study aimed to analyze the effect of Bletilla striata polysaccharide(BSP) on endogenous metabolites in serum of tumor-bearing mice treated with 5-fluorouracil(5-FU) by untargeted metabolomics techniques and explore the mechanism of BSP in alleviating the toxic and side effects induced by 5-FU. Male BALB/C mice were randomly divided into a normal group, a model group, a 5-FU group, and a 5-FU + BSP group, with eight mice in each group. Mouse colon cancer cells(CT26) were transplanted into the mice except for those in the normal group to construct the tumor-bearing mouse model by subcutaneous injection, and 5-FU chemotherapy and BSP treatment were carried out from the second day of modeling. The changes in body weight, diarrhea, and white blood cell count in the peripheral blood were recorded. The mice were sacrificed and sampled when the tumor weight of mice in the model group reached approximately 1 g. TUNEL staining was used to detect the cell apoptosis in the small intestine of each group. The proportions of hematopoietic stem cells and myeloid progenitor cells in bone marrow were measured by flow cytometry. Five serum samples were selected randomly from each group for untargeted metabolomics analysis. The results showed that BSP was not effective in inhibiting colon cancer in mice, but diarrhea, leukopenia, and weight loss caused by 5-FU chemotherapy were significantly improved after BSP intervention. In addition, apoptotic cells decreased in the small intestinal tissues and the percentages of hematopoietic stem cells and myeloid progenitor cells in bone marrow were significantly higher after BSP treatment. Metabolomics results showed that the toxic and side effects of 5-FU resulted in significant decrease in 29 metabolites and significant increase in 22 metabolites in mouse serum. Among them, 19 disordered metabolites showed a return to normal levels in the 5-FU+BSP group. The results of pathway enrichment indicated that metabolic pathways mainly involved pyrimidine metabolism, arachidonic acid metabolism, and steroid hormone biosynthesis. Therefore, BSP may ameliorate the toxic and side effects of 5-FU in the intestinal tract and bone marrow presumably by regulating nucleotide synthesis, inflammatory damage, and hormone production.

RESUMO

The study aimed to investigate the effect of anemoside B4(B4) on fatty acid metabolism in mice with colitis-associated cancer(CAC). The CAC model was established by azoxymethane(AOM)/dextran sodium sulfate(DSS) in mice. Mice were randomly divided into a normal group, a model group, and low-, medium-, and high-dose anemoside B4 groups. After the experiment, the length of the mouse colon and the size of the tumor were measured, and the pathological alterations in the mouse colon were observed using hematoxylin-eosin(HE) staining. The slices of the colon tumor were obtained for spatial metabolome analysis to analyze the distribution of fatty acid metabolism-related substances in the tumor. The mRNA levels of SREBP-1, FAS, ACCα, SCD-1, PPARα, ACOX, UCP-2, and CPT-1 were determined by real-time quantitative PCR(RT-qPCR). The results revealed that the model group showed decreased body weight(P<0.05) and colon length(P<0.001), increased number of tumors, and increased pathological score(P<0.01). Spatial metabolome analysis revealed that the content of fatty acids and their derivatives, carnitine, and phospholipid in the colon tumor was increased. RT-qPCR results indicated that fatty acid de novo synthesis and β-oxidation-related genes, such as SREBP-1, FASN, ACCα, SCD-1, ACOX, UCP-2, and CPT-1 mRNA expression levels increased considerably(P<0.05, P<0.001). After anemoside B4 administration, the colon length increased(P<0.01), and the number of tumors decreased in the high-dose anemoside B4 group(P<0.05). Additionally, spatial metabolome analysis showed that anemoside B4 could decrease the content of fatty acids and their derivatives, carnitine, and phospholipids in colon tumors. Meanwhile, anemoside B4 could also down-regulate the expression of FASN, ACCα, SCD-1, PPARα, ACOX, UCP-2, and CPT-1 in the colon(P<0.05, P<0.01, P<0.001). The findings of this study show that anemoside B4 may inhibit CAC via regulating fatty acid metabolism reprogramming.

RESUMO

Sugar reduction and restriction have become one of the most urgent health demands as the number of obese people increases globally. Sugar substitutes (mainly classified into sugar alcohols, natural sweeteners, and artificial sweeteners) have been widely used in food processing as alternatives to sugar for their low energy and high sweetness. Thus, the classification, metabolism pathways, advantages, applications, and human health effects of sugar substitutes, their effects on human health were introduced, and the relationships between sugar substitutes and obesity, diabetes, intestinal microbes, hypertension, and all-cause mortality were emphatically summarized in this paper. Generally, long-term high intake of sugar substitutes is associated with adverse health outcomes such as elevated blood pressure, higher risks of diabetes, cancer, and increased all-cause mortality. Meanwhile, sugar alcohols and natural sweeteners are more likely to associate with beneficial effects on human gut microbial diversity, while artificial sweeteners associate with imbalance of gut microbiota based on available evidence. Current published research focuses on single sugar substitute exposure with varied health effects, while nearly half of commercial sugar substitute products contain two or more sugar substitutes. The effects of exposure to multiple sugar substitutes on human health are not clear yet, so further strengthening the relevant epidemiological and molecular mechanism research is necessary.

RESUMO

Fusobacterium nucleatum (F. nucleatum) is an early pathogenic colonizer in periodontitis, but the host response to infection with this pathogen remains unclear. In this study, we built an F. nucleatum infectious model with human periodontal ligament stem cells (PDLSCs) and showed that F. nucleatum could inhibit proliferation, and facilitate apoptosis, ferroptosis, and inflammatory cytokine production in a dose-dependent manner. The F. nucleatum adhesin FadA acted as a proinflammatory virulence factor and increased the expression of interleukin(IL)-1β, IL-6 and IL-8. Further study showed that FadA could bind with PEBP1 to activate the Raf1-MAPK and IKK-NF-κB signaling pathways. Time-course RNA-sequencing analyses showed the cascade of gene activation process in PDLSCs with increasing durations of F. nucleatum infection. NFκB1 and NFκB2 upregulated after 3 h of F. nucleatum-infection, and the inflammatory-related genes in the NF-κB signaling pathway were serially elevated with time. Using computational drug repositioning analysis, we predicted and validated that two potential drugs (piperlongumine and fisetin) could attenuate the negative effects of F. nucleatum-infection. Collectively, this study unveils the potential pathogenic mechanisms of F. nucleatum and the host inflammatory response at the early stage of F. nucleatum infection.

RESUMO

Objective: Differential flora and differential metabolites shared by the intestinal and respiratory tracts of rats were screened to analyze the possible role of changes in intestinal flora and metabolites in the progression of pneumoconiosis in rats. Methods: In April 2020, 18 SD rats were randomly divided into three groups (control group, coal mine dust group and silica group, 6 in each group) , rats in the coal mine dust group and silica group were perfused with 1 ml of 50 mg/ml coal mine well dust suspension and silica suspension by nontracheal exposure, respectively. While rats in the control group were perfused with an equal dose of sterilized normal saline. Twenty four weeks after dust staining, rat feces, throat swabs, and lung lavages were collected. 16SrDNA gene sequencing and UHPLC-QTOF-MS untargeted metabolomics were used to analyze the flora and metabolites in feces, throat swabs and lung lavage fluid of rats in each group, to screen for shared differential flora and shared differential metabolites in intestinal and respiratory tract, and the correlation analysis between the differential flora and metabolites was performed using Spearman's statistics. Results: Compared with the control group, a total of 9 species shared differential flora between intestinal and respiratory tract were screened at phylum level, and a total of 9 species shared differential genus between intestinal and respiratory tract were screened at genus level in the coal mine dust group, mainly Firmicutes, Actinobacteria, Streptococcus, Lactobacillus, etc. Compared with the control group, a total of 9 shared differential flora were screened at the phylum level, and a total of 5 shared differential genus were screened at the genus level in the silica group, mainly Proteobacteria, Actinobacteria, Allobactera, Mucilaginibacter, etc. Compared with the control group, a total of 7 shared differential metabolites were screened for up-regulation of Stigmatellin, Linalool oxide and Isoleucine-leucine in both intestinal and respiratory tract in the coal mine dust group. Compared with the control group , a total of 19 shared differential metabolites werescreened in the silica group, of which Diethanolamine, 1-Aminocyclopropanecarboxylic acid, Isoleucine-leucine, Sphingosine, Palmitic acid, D-sphinganine, 1, 2-dioleoyl-sn-glycero-3-phosphatidylcholine, and 1-Stearoyl-2-oleoyl-sn-glycerol 3-phosphocholine were up-regulated in both the intestinal and respiratory tract. Conclusion: There is a translocation of intestinal and respiratory flora in pneumoconiosis rats, and rats have an imbalance of lipid metabolism during the progression of pneumoconiosis.

RESUMO

Objective: To investigate the effects of polyetheretherketone, zirconium dioxide, and titanium abutment materials on the expression of genes and proteins related to hemidesmosome adhesion in human gingival epithelial cells, in order to screen out abutment materials that are easier for epithelial adhesion. Methods: Forty-eight specimens were prepared in each of the three materials, polyetheretherketone, zirconium oxide, and pure titanium specimens. The surface morphology of each group of specimens was observed by scanning electron microscopy, the surface roughness was measured by the white light interferometer, and the contact angle was measured by optical contact angle measuring instrument. The early adhesion status of human gingival epithelial cells on the surface of each group of specimens was observed by scanning electron microscopy, and the proliferation ability of human gingival epithelial cells on the surface of each group of specimens was assessed by using a cell counting kit, and the expression levels of genes and proteins related to the adhesion of human gingival epithelial cells on the surface of each group of specimens were detected by real-time fluorescence quantitative PCR and Western blotting, respectively. Results: The surface morphology of the three groups of specimens was flat and smooth. The mean roughness (Ra value) of the polyetheretherketone, zirconia, and pure titanium groups were (95.63±2.06), (37.93±3.56), and (134.2±4.62) nm (F=368.16, P<0.001), respectively, and the mean maximum height (Rz value) was (2.42±0.22), (0.87±0.10) and (3.77±0.28) nm (F=91.95, P<0.001), with statistical significance (P<0.05). The contact angles were 81.23°±0.91°, 82.08°±2.10°, and 80.47°±1.85°, respectively, with no statistically significant overall difference (F=0.45, P=0.658). Human gingival epithelial cells showed irregular shapes such as flattened and extended polygons and polygons on the surface of the three groups of specimens, exhibiting a typical paving stone pattern. The differences in cell proliferation among the three groups at 1 and 3 d of culture were not statistically significant (P>0.05). Cell proliferation in the polyetheretherketone group was significantly greater those those in the zirconia and pure titanium groups at 5 and 7 d of culture (P<0.05). The mRNA expression levels and protein expression levels of laminin α3, integrin β4, and collagen ⅩⅦ in the polyetheretheretherketone group at 3 and 7 d of incubation were significantly greater than those in the zirconium oxide and pure titanium groups at the same time points (P<0.05). Conclusions: Polyetheretherketone is more conducive to the adhesion of hemidesmosome in human gingival epithelial cells than zirconium dioxide and pure titanium abutment materials.

RESUMO

Objective: To explore the relevant factors of work-related musculoskeletal disorders (WMSDs) among dentists through Meta analysis, providing a basis for the prevention and control of WMSDs among dentists. Methods: In April 2022, cross-sectional research literatures on the prevalence correlation of WMSDs among Chinese dentists were searched in databases such as China National Knowledge Infrastructure, Wanfang, VIP, PubMed, Web of Science, and Em Base database. The search was conducted from the establishment of the database until April 2022, literatures were selected using keywords such as musculoskeletal disorders and dentists. To extract gender, age, length of service, disease classification and other related influencing factors as indicator, and prevalence was selected as the outcome indicator. After evaluating the quality of the literatures, RevMan 5.3 software was used to calculate the combined RD (95%CI) values of the included literatures. Results: A total of 15 articles were included, with a total sample size of 3646 people. Meta analysis results showed that the prevalence of WMSDs among dentists in China was 80%, and the top three parts of the incidence rates were 65% of the waist, 58% of the neck, and 50% of the back. Gender, age, length of service, region and disease classification all increased the risk of WMSDs, and the combined effect size were 75%, 78%, 71%, 77% and 82% respectively (P<0.05) . Conclusion: The occurrence of WMSDs among dentists in China is related to multiple factors such as gender, age, length of service and disease classification. The above risk factors should be taken into account in the workplace and preventive measures should be actively implemented to prolong the working life of dentists.
