In order to obtain better quality cookies, food 3D printing technology was employed to prepare cookies. The texture, color, deformation, moisture content, and temperature of the cookie as evaluation indicators, the influences of baking process parameters, such as baking time, surface heating temperature and bottom heating temperature, on the quality of the cookie were studied to optimize the baking process parameters. The results showed that the baking process parameters had obvious effects on the texture, color, deformation, moisture content, and temperature of the cookie. All of the roasting surface heating temperature, bottom heating temperature and baking time had positive influences on the hardness, crunchiness, crispiness, and the total color difference(ΔE) of the cookie. When the heating temperatures of the surfac and bottom increased, the diameter and thickness deformation rate of the cookie increased. However,with the extension of baking time, the diameter and thickness deformation rate of the cookie first increased and then decreased. With the surface heating temperature of 180 ℃, the bottom heating temperature of 150 ℃, and baking time of 15 min, the cookie was crisp and moderate with moderate deformation and uniform color. There was no burnt phenomenon with the desired quality. Research results provided a theoretical basis for cookie manufactory based on food 3D printing technology. 展开更多

BACKGROUND Intraoperative hyperlactatemia often affects circulatory stability,vital organ function,and postoperative recovery,poses a serious prognostic risk,and requires considerable attention from anesthesiologists.Here,we describe a case of hyperlactatemia during the postoperative resection of liver metastases after chemotherapy for sigmoid colon cancer.This did not affect the patient's circulatory stability or quality of awakening,which is rarely reported in clinical practice.We present our management experience with the aim of providing a reference for future studies and clinical practice.CASE SUMMARY A 70-year-old female patient was diagnosed with postoperative liver metastasis following chemotherapy for sigmoid colon cancer.Laparoscopic right hemicolectomy and cholecystectomy under general anesthesia were required.Metabolic disorders,primarily hyperlactatemia,often occur intraoperatively.After treatment,other indices quickly returned to normal,lactate levels decreased slowly,and hyperlactatemia persisted during the awakening period.However,this did not affect the patient's circulatory stability or awakening quality.This condition has rarely been clinically reported.Therefore,we report our management experience in order to guide clinical practice in this regard.Hyperlactatemia did not affect circulatory stability or the quality of awakening.We considered that active intraoperative rehydration avoided serious harm to the organism caused by hyperlactatemia due to insufficient tissue perfusion,while hyperlactatemia caused by decreased lactate clearance due to impaired liver function associated with surgical resection had a mild effect on the function of important organs.CONCLUSION Active intraoperative rehydration avoided serious harm to the organism caused by hyperlactatemia.Strengthening body temperature protection could improve lactate circulation. 展开更多

BACKGROUND The gut microbiota is strongly associated with radiation-induced gut damage.This study aimed to assess the effectiveness and safety of intestinal microecological transplantation for treating patients with chronic radiation enteritis.CASE SUMMARY A 64-year-old female with cervical cancer developed abdominal pain,diarrhea,and blood in the stool 1 year after radiotherapy.An electronic colonoscopy was performed to diagnose chronic radiation enteritis.Two courses of intestinal microecological transplantation and full-length 16S rRNA microbiological analysis were performed.The patient experienced short-and long-term relief from symptoms without adverse effects.Whole 16S rRNA sequencing revealed significant differences in the intestinal flora’s composition between patient and healthy donors.Pathogenic bacteria,such as Escherichia fergusonii and Romboutsia timonensis,were more in the patient.Beneficial bacteria such as Faecalibacterium prausnitzii,Fusicatenibacter saccharivorans,Ruminococcus bromii,and Bifidobacterium longum were more in the healthy donors.Intestinal microbiota transplantation resulted in a significant change in the patient's intestinal flora composition.The composition converged with the donor's flora,with an increase in core beneficial intestinal bacteria,such as Eubacterium rectale,and a decrease in pathogenic bacteria.Changes in the intestinal flora corresponded with the patients'alleviating clinical symptoms.CONCLUSION Intestinal microecological transplantation is an effective treatment for relieving the clinical symptoms of chronic radiation enteritis by altering the composition of the intestinal flora.This study provides a new approach for treating patients with chronic radiation enteritis. 展开更多

BACKGROUND The extraction of maxillary impacted teeth is a common procedure in oral surgery,frequently complicated by oroantral communications.For less-experienced clinicians,accurately assessing the difficulty and associated risks of maxillary third molar extractions remain a significant challenge.CASE SUMMARY We present a case involving disparate outcomes following bilateral extraction of maxillary third molars.Using cone-beam computed tomography and three-dimensional software,we conducted a digital assessment of the factors contributing to extraction difficulty and risk,controlling for potential confounders.Key variables analyzed included alveolar bone volume,bone quality,crown-root angulation,and maxillary sinus mucosal thickness.Additionally,we introduce the novel concept of"tegmen bone"to quantitatively evaluate the bone mass between the teeth and the maxillary sinus.This unique case,with differing outcomes on opposite sides of the same patient,provided an opportunity to minimize extraneous variables and focus on the local anatomical factors influencing the procedures,thereby improving the precision of our analysis.CONCLUSION This case highlights the potential utility of predictive analysis in guiding the management of complex tooth extractions. 展开更多

BACKGROUND The clinical manifestations of trisomy 7 mosaicism are diverse and nonspecific,so prenatal diagnosis is very difficult.CASE SUMMARY Two pregnant women with abnormal prenatal screening results were included.One was a 22-year-old woman(G1P0).At 31st week of gestation,ultrasound revealed that the posterior horn of the left lateral ventricle was 10 mm and the right renal pelvis had a separation of 7 mm.The other pregnant woman was 33 years old(G2P1L1A0),and her fetus was found to have a cardiac malformation at the 24th week of gestation.Copy number variation sequencing,whole-exome sequencing and karyotype analysis were carried out after amniocentesis,and both fetuses were diagnosed with trisomy 7 mosaicism.After parental counseling,one woman continued the pregnancy,and the other woman terminated the pregnancy.CONCLUSION In trisomy 7 mosaicism,the low proportion of trisomy does not lead to abortion,but can result in abnormal fetal development,which can be detected via ultrasound.Therefore,clinicians need to pay more attention to various aspects of fetal growth and development,combining with imaging,cellular,molecular genetics and other methods to perform comprehensive evaluations of fetuses to provide more reliable genetic counseling for pregnant women. 展开更多

The International Accounting Standards Board (IASB) and the Financial Accounting Standards Board (FASB) stress the importance of high-quality 'financial reports. From a scientific point of view, however, major methodological drawbacks can arise when trying to arrive at a comprehensive assessment and evaluation of the decision usefulness of financial reports. In this conceptually-based exploratory study, the authors construct a 33-item index aimed at operationalizing decision usefulness in terms of the fundamental and enhancing qualitative characteristics laid out in the conceptual framework (CF) of the IASB (2010). Using a matched-pairs sample design, which includes 70 UK annual reports and 70 US 10-K reports for 2010, the results of test-retest and inter-rater reliability tests show that these multiple items, which were based on items used in previous research, can be measured in a reliable manner. At the same time, the results of an exploratory factor analysis indicate that the IASB qualitative characteristics cannot be measured separately when the 33-item index is applied. At an aggregate level, the results of paired-sample t-tests reveal that UK reports score on average higher than US 10-K reports, which suggests that the overall quality of UK reports is better. The findings of this study add to the existing literature on the empirical evaluation of the effects of international accounting standards, showing that, as compared with 10-K reports, UK annual reports provide more information on topics such as corporate social responsibility (CSR), corporate governance, and annual bonus schemes. On the other hand, US reports outperform UK reports with respect to the content of fair value information, cash flow statements, off-balance financing, and audit reporting. 展开更多

BACKGROUND Meta-analysis,a form of quantitative review,is an attempt to combine data from multiple independent studies to improve statistical power.Because of the complexity of process involved in study selection,data analysis,and evaluation of bias and heterogeneity,checklists have been prepared by the Institutes of Medicine(IOM),Preferred Reporting Items for Systemic Reviews and Metaanalyses(PRISMA),and Meta-analyses of Observational Studies in Epidemiology(MOOSE)to standardize the reporting quality of a meta-analysis.AIM To use these checklists to assess the reporting quality of the coronavirus disease-2019(COVID-19)meta-analysis literature relevant to laboratory hematology.METHODS After a search of the literature 19 studies were selected for analysis,including 10 studies appearing in the preprint literature(studies that can be identified by database search but have not yet completed peer review).RESULTS The average IOM(76%of required elements completed),PRISMA(75%of required elements completed),and MOOSE(60%of required elements completed)scores enumerated demonstrated a reporting quality inferior to that of earlier reports of pathology and medicine meta-analyses.There was no statistically significant difference in performance between accepted/published and preprint studies.Comparison of the results of PRISMA and MOOSE studies demonstrated a weak positive correlation(Pearson’s correlation coefficient=0.39).CONCLUSION The most common deficits in the studies included sensitivity analysis,assessment for bias,and details of the search strategy.Although the COVID-19 laboratory hematology meta-analysis literature can be a helpful source of information,readers should be aware of these reporting quality deficits. 展开更多

AIM: To evaluate the impact of spherical and aspherical intraocular lenses on the postoperative visual quality of age-related cataract patients using Optical Quality Analysis System (OQAS). METHODS: Seventy-four eyes with age-related cataracts were randomly divided into spherical and aspherical lens implantation groups. Best-corrected visual acuity (BCVA) was measured preoperatively, one day, one week, two weeks, one month and two months after surgery. A biometric systems analysis using the OQAS objective scattering index (OSI) was performed. RESULTS: There were no significant differences in visual acuity (P〉0.05) before and after spherical and aspheric lens implantation. There was a negative linear correction between the OSI value and BCVA (t-=-0.634, P=-0.000), and positive corrections between the OSI value and the lens LOCUS III value of nucleus color (NC), nucleus opacity (NO), cortex (C) and posterior lens capsular (P) (r=0.704, P=0.000; r=0.514, P=0.000; r=0.276, P=0.020; r=0.417, P=-0.000, respectively). OSI values of spherical vs aspherical lenses were 11.5±3.6 vs 11.8±3.4, 4.1±0.9 vs 3.3±0.8, 3.5±0.9 vs 2.7±0.7, 3.3±0.8 vs 2.6±0.7, 3.2±0.7 vs 2.5±0.8, and 3.2±0.8 vs 2.50.8 before and ld, 1, 2wk, 1 and 2mo after surgery, respectively. All time points varied significantly (P〈0.01) between the two groups. CONCLUSION: Aspherical IOLs does not significantly affect visual acuity compared with spherical IOLs. The OSI value, was significantly lower in the aspherical lens group compared with the spherical lens. This study shows that objective visual quality of aspheric IOLs is better than that of the spherical lens by means of OQAS biological measurement method. 展开更多

This study analyzes the signal quality and the accuracy of BeiDou 3 rd generation Satellite Navigation System(BDS3) Precise Point Positioning(PPP) in the Arctic Ocean. Assessment of signal quality of BDS3 includes signal to noise ratio(SNR), multipath(MP), dilution of precision(DOP), and code-minus-carrier combination(CC). The results show that, 5 to 13 satellites are visible at any time in the Arctic Ocean area as of September 2018, which are sufficient for positioning. In the mid-latitude oceanic region and in the Arctic Ocean, the SNR is 25–52 dB Hz and the MP ranges from-2 m to 2 m. As the latitude increases, the DOP values show large variation, which may be related to the distribution of BDS satellites. The CC values of signals B1 I and BIC range from-5 m to 5 m in the mid-latitude sea area and the Arctic Ocean, which means the effect of pseudorange noise is small. Moreover, as to obtain the external precise reference value for GNSS positioning in the Arctic Ocean region is difficult, it is hard to evaluate the accuracy of positioning results. An improved isotropy-based protection level method based on Receiver Autonomous Integrity Monitoring is proposed in the paper, which adopts median filter to smooth the gross errors to assess the precision and reliability of PPP in the Arctic Ocean. At first, the improved algorithm is verified with the data from the International GNSS Service Station Tixi. Then the accuracy of BDS3 PPP in the Arctic Ocean is calculated based on the improved algorithm. Which shows that the kinematic accuracy of PPP can reach the decimeter level in both the horizontal and vertical directions, and it meets the precision requirements of maritime navigation. 展开更多
