RESUMO
PURPOSE: To determine the accuracy of manual compass measurement and trigonometric determination of proptosis (MCMATDP). METHODS: This agreement study included 120 eyes without eye diseases or injury of 60 patients who visited the ophthalmic clinic of Peking University Shenzhen Hospital from February 2020 to June 2020. The absolute values of proptosis were measured by MCMATDP and computed tomography (CT). The differences between the two methods were shown by Bland-Altman plot. RESULTS: The cohort comprised 25 males and 35 females (average age 38.3 years). The absolute value of proptosis measured by CT was correlated with the MCMATDP. Further analysis showed that a 95% limit of agreement (LoA) was - 0.53 to 0.60 mm in the right eye and - 0.46 to 0.55 mm in the left eye between CT and MCMATDP. In addition, the 95% LoA was - 0.49 to 0.60 mm in both eyes between the two methods. All points were < 5% in Bland-Altman plots. CONCLUSIONS: Compared to CT, MCMATDP is rather consistent in proptosis measurement. The new method is feasible in clinical practice when measuring proptosis. With the development of non-contact intelligent measurement software and the continuous improvement in measurement accuracy, a non-invasive, simple, and inexpensive measurement mode is true based on the theory of MCMATDP.

OBJECTIVES: Cervical squamous cell carcinoma is the most common cancer in female reproductive system. This study aims to explore the effect of microRNA-9-5p (miR-9-5p) on the migration, invasion, and epithelial-mesenchymal transition (EMT) process of cervical squamous cells. METHODS: Bioinformatics were used to predict the miRNAs that could bind to E-cadherin (E-cad). The Cancer Genome Atlas (TCGA) database was used to analyze and extract significantly differentially expressed miRNAs from part of cervical squamous cell carcinoma tissues and normal cervical tissues, and miR-9-5p was selected as the main research target. The translated regions (UTR) of wild-type E-cad (E-cad-WT 3'-UTR) or the 3'-UTR of mutant E-cad (E-Cad-MUT 3'-UTR) was transfected with miR-9-5p mimic normal control (NC), and miR-9-5p mimic was co-transfected human embryonic kidney cells (293T). The relationship between miR-9-5p and E-cad was detected by double luciferase assay. The expression of miR-9-5p in normal cervical epithelial cell lines (H8) and cervical squamous cell lines (C33A, siha, caski and Me180) were detected by quantitative real-time PCR. Then, the experiments were divided into groups as follows: a block control group, an overexpression control group (mimic-NC group), a miR-95p overexpression group (mimic group), an inhibitory expression control group (inhibitor-NC group), and a miR-9-5p inhibitory expression group (inhibitor group). The changes of migration ability were detected by scratch assay. Transwell invasion assay was used to analyze the changes of invasion ability, and the mRNA and protein changes of E-cad and vimentin were detected by quantitative real-time PCR and Western blotting. RESULTS: MiR-9-5p had a targeting binding relationship with E-cad. Compared with the normal cervical tissue H8 cell line, the miR-9-5p was highly expressed in cervical cancer cell lines (C33A, siha, caski and Me180) (all P<0.05). The luciferase activity of E-cad-MUT was increased compared with that of E-cad-WT in miR-9-5p mimic cells (P<0.05). Compared with the blank control group, the protein and mRNA expressions of E-cad were decreased in the miR-9-5p mimic group (both P<0.05), which were increased in the miR-9-5p inhibitor group (both P<0.05). Compared with H8 cell line, the miR-9-5p was highly expressed in the cervical squamous cell lines (all P<0.05). Compared with the mimic-NC group, the distance of wound healing, the number of caski and Me180 cells invaded below the membrane, and the mRNA and protein expressions of vimentin were all increased in the miR-9-5p mimic group (all P<0.05), while the mRNA and protein of E-cad were decreased (both P<0.05). Compared with the inhibitor-NC group, the distance of wound healing, the number of caski and Me180 cells invading the membrane, and the mRNA and protein expressions of vimentin were decreased in the miR-9-5p inhibitor group (all P<0.05), but the mRNA and protein expressions of E-cad were increased (both P<0.05). CONCLUSIONS: The miR-9-5p is highly expressed in cervical squamous cell carcinoma, which can increase the migration and invasion ability, and promote the EMT process of cancer cells.

BACKGROUND: Preoperative neoadjuvant chemotherapy (NACT) has been widely used in developing countries for the treatment of patients with International Federation of Gynecology and Obstetrics (FIGO) stages IB3 and IIA2 cervical cancer. However, the effectiveness of NACT and treatment options for NACT-insensitive patients have been concerning. This study will assess prognostic differences between NACT and primary surgery treatment (PST), determine factors associated with prognosis, and explore better adjuvant treatment modalities for NACT-insensitive patients. METHODS: This study analyzed clinical characteristics, pathological characteristics, treatment options, and follow-up information of 774 patients with FIGO stages IB3 and IIA2 cervical cancer from 28 centers from January 2016 to October 2019 who participated in a multicenter, prospective, randomized controlled trial. RESULTS: For patients undergoing NACT, the 5-year OS and PFS rate was 85.8 and 80.5% respectively. They were similar in the PST group. There was no significant difference in OS and PFS between clinical response (CR)/partial response (PR) groups and stable disease (SD)/progressive disease (PD) groups. Apart from deep cervical invasion (p = 0.046) affecting OS for patients undergoing NACT, no other clinical and pathological factors were associated with OS. 97.8% of NACT-insensitive patients opted for surgery. If these patients did not have intermediate- or high-risk factors, whether they had undergone postoperative adjuvant therapy was irrelevant to their prognosis, whereas for patients with intermediate- or high-risk factors, adjuvant chemotherapy resulted in better PFS (chemotherapy vs. no therapy, p < 0.001; chemotherapy vs. radiotherapy, p = 0.019) and OS (chemotherapy vs. no therapy, p < 0.001; chemotherapy vs. radiotherapy, p = 0.002). CONCLUSIONS: NACT could be a choice for patients with FIGO stages IB3 and IIA2 cervical cancer. The main risk factor influencing prognosis in the NACT group is deep cervical invasion. After systematic treatment, insensitivity to NACT does not indicate a poorer prognosis. For NACT-insensitive patients, Chinese prefer surgery. Postoperative adjuvant therapy in patients with no intermediate- or high-risk factors does not improve prognosis, and chemotherapy in patients with intermediate- and high-risk factors is more effective than radiation therapy and other treatments. TRIAL REGISTRATION: The study was prospectively registered on ClinicalTrials.gov (NCT03308591); date of registration: 12/10/2017.

PURPOSE: To compare the pupil size of the original mydriasis and repeat mydriasis at the pupil shrinkage stage. METHODS: Randomized prospective study. In total, 60 eyes of 30 patients aged 50-70 with age-related cataracts were included. Pupil sizes were measured by the Sirius system before mydriasis, after the first batch of mydriasis, and after the second batch of mydriasis which was 5 h later. Statistical analysis was performed using MedCalc statistical software version 20.0.3 RESULTS: The pupil size of the second batch of mydriasis 5 h later was smaller than the first batch of mydriasis (3.94 ± 0.88 mm vs 5.12 ± 0.96 mm, P < 0.0001). CONCLUSIONS: Less efficiency repeat mydriasis several hours later compared with original mydriasis in our study suggests that preparation of mydriasis at an appropriate time is necessary for ophthalmological operations. The effect of repeat mydriasis again by tropicamide at the shrinkage stage still needs to be explored.

As an emerging nitrogen-rich 2D carbon material, graphitic carbon nitride (CN) has drawn much attention for applications ranging from photo-/electrocatalysts to biosensors. Interfacial modification of CN is fundamentally vital but is still in its infancy and remains challenging due to the low reactivity of CN. Here we report that, in conjunction with a π-π stacking interaction, bulk CN could be simultaneously exfoliated via facile mechanical grinding. The obtained CN nanosheets (m-CNNS) not only retained the pristine optoelectronic properties of bulk CN but also enriched a friendly interface for further coupling biomolecules with advanced properties, overcoming the deficiencies of CN in surface science. The m-CNNS were further covalently linked to a DNA probe, and the resultant electrochemiluminescent biosensor for the target DNA exhibited much enhanced sensitivity with respect to that obtained by direct physical absorption of the DNA probe on unmodified CNNS. This noncovalent exfoliation and interfacial modification should greatly expand the scope of potential applications of CN in areas such as biosensing and should also be applicable to other 2D materials in interface modulation.
RESUMO
Vascular endothelial growth factor (VEGF), one of the most important angiogenic factor, can impact the tumor cell proliferation and invasion, but the mechanism remains unclear. This study is to investigate the key proteins which may play an important role in the VEGF-induced progress of ovarian cancer cells. The total protein from HO-8910 cells was separated by two-dimensional electrophoresis (2-DE), and differentially expressed proteins were identified by matrix-assisted laser desorption and ionization time-of-flight tandem mass spectrometry (MALDI-TOF MS) and PDQuest image analysis software. Furthermore, real-time PCR, Western blot, and immunocytochemistry were also used to confirm different expression levels of differential proteins. Morphological changes and invasion capability were evaluated by electron microscope and Matrigel invasion assay, respectively. The highly reproducible and well-resolved 2-DE patterns of both HO-8910/VEGF and HO-8910 cells were acquired. A total of 17 expressed differential proteins were identified, 8 proteins were upregulated (ACTB, TIM, PDIA3, PDIA1, DCTN2, KIC17, SIAS, and KIC10) and 9 downregulated (KIC18, GRP78, CAPG, PPIA, ROA2, LMNA, EZRI, ADRM1, and ENOA). Ultrastructure of VEGF-treated group showed more malignant characteristic compared with control group, an obvious increase in the number of cells penetrating the Matrigel membrane in VEGF-treated group (P < 0.05). These results suggested that VEGF could impact ovarian cancer's malignant progression by regulating expression of associated proteins.

PURPOSE: To compare the corneal biomechanical properties before and after small incision lenticule extraction (SMILE) and femtosecond laser-assisted LASIK in different levels of myopia with the Ocular Response Analyzer (Reichert Ophthalmic Instruments, Depew, NY). METHODS: A total of 187 and 79 eyes that received SMILE or LASIK, respectively, between January and June 2013 at Zhongshan Ophthalmic Center were enrolled in this study. Patients were grouped according to surgery type (SMILE or LASIK) and -6.00 diopters (D) or less (> -6.00 D) or myopia greater than -6.00 D (>-6.00 D). Corneal hysteresis, corneal resistance factor, and 37 waveform parameters were recorded and compared preoperatively and at 1 week and 1 and 3 months postoperatively. RESULTS: There was a significant decrease of corneal hysteresis, corneal resistance factor, p1area, and p2area, and an increase of path1 and path2 in both SMILE and LASIK. In myopia -6.00 D or less, the differences between SMILE and LASIK were not significant (P > .05), but in myopia greater than -6.00 D, the corneal hysteresis, corneal resistance factor, p1area, and p2area decreased significantly more in LASIK than in SMILE (P < .05). CONCLUSIONS: When comparing SMILE with LASIK, myopia was greater than -6.00 D, and the corneal hysteresis, corneal resistance factor, p1area, and p2area decrease was less after SMILE.

PURPOSE: This is a meta-analysis to compare the clinical results between unilateral and bilateral pedicle screw (PS) fixation in lumbar interbody fusion. METHODS: We included published studies with no language and year restrictions. The criteria which Koes et al. designed in 1995 were used to evaluate the risk of bias of the included studies. All data were analyzed by Review Manager 5.1. The primary outcomes included fusion rate and screw complications, and the secondary outcomes were operative time, blood loss, and hospital time. RESULTS: A total of five prospective studies with 407 patients were included in the current meta-analysis, and four of them were randomized controlled trials. There was no significant difference between unilateral PS fixation and bilateral PS fixation group in fusion rate and screw complications (fusion rate: OR 0.54, Z = 1.33, P = 0.18, I (2) = 0 %; screw complications: OR 1.45, Z = 0.71, P = 0.48; I (2) = 44 %). In the secondary outcomes, the operative time (Z = 3.35, P = 0.0008; I (2) = 95 %) and blood loss (Z = 4.35, P < 0.0001; I (2) = 98 %) was significantly higher in bilateral PS fixation group than in unilateral PS fixation group. Besides, no significant difference was found in hospital time (Z = 1.19, P = 0.24; I (2) = 99 %). CONCLUSIONS: In our meta-analysis, we found that unilateral PS fixation in lumbar fusion was as effective as bilateral PS fixation for lumbar degenerative diseases without major instability, no significant difference was found in hospital time, fusion rate and screw complications. In terms of operative time and blood loss, unilateral PS fixation even produced better results.

OBJECTIVE: To analyze the expression of vascular endothelial growth factor (VEGF), miR-205, Ezrinand Lamin A/C in ovarian cancer tissues. METHODS: The expression of VEGF in the serum of epithelial ovarian cancer and that of healthy volunteers were detected by enzyme-linked immunosorbent assay; the expressions of vascular endothelial growth factor receptor 1 (VEGFR-1), VEGFR-2, Ezrin and Lamin A/C were detected by immunohistochemistry and the micro-vessel density (MVD) of CD31 was detected by immunohistochemistry in epithelial ovarian cancer, benign ovarian and normal ovarian specimens; and the expression of miR-205, Ezrin and Lamin A/C were detected by real-time PCR in epithelial ovarian cancer, benign ovarian and normal ovarian specimens. RESULTS: The expression of VEGF in the serum of epithelial ovarian cancer patients (116.10± 11.94) was significantly higher than that of healthy volunteers (40.04±4.97, P<0.05). The positive expression rates of VEGFR-1 and VEGFR-2 in the epithelial ovarian cancer specimens were 75.9% and 91.4% respectively, which were significantly higher than that in the benign ovarian and the normal ovarian specimens (P<0.05). No differences were observed in the positive expression rates of VEGFR-1 and VEGFR-2 between the benign ovarian and the normal ovarian specimens (P>0.05). The average length of MVD in the epithelial ovarian cancer specimens (7.56±0.51), was significantly higher than that in the normal ovarian specimens (1.22±0.56, P<0.05) and in the benign ovarian specimens (0.7±0.39, P<0.05). No differences were observed in the average length of MVD between the benign ovarian and the normal ovarian specimens (P>0.05). The relative expression level of miR-205 was 0.106±0.035 in the epithelial ovarian cancer specimens, which was significantly higher than that in the normal ovarian specimens (0.0007±0.0005, P<0.05); the relative expression level of miR-205 in the benign ovarian specimens was (0.0002±0.0002), higher than that in the normal ovarian specimens, but with no significance (P>0.05). The positive expression rates of Ezrin and Lamin A/C in the epithelial ovarian cancer specimens were 51.7% and 60.3%, respectively, which were significantly lower than those in the benign ovarian and the normal ovarian specimens (P<0.05). No differences were observed in the positive expression rates of Ezrin and Lamin A/C between the benign ovarian and the normal ovarian specimens (P>0.05). The relative expression levels of Ezrin and Lamin A/C mRNA in the epithelial ovarian cancer specimens were (0.026±0.003) and (0.060±0.007), respectively, which were significantly lower than those in the normal ovarian specimens (P<0.05). There was no statistical significance between the relative expression level of Ezrin and Lamin A/C mRNA in the epithelial ovarian cancer specimens and that in the benign ovarian specimens (0.029± 0.011, 0.089 ± 0.019; P>0.05) . CONCLUSION: VEGF is significantly expressed in the serum of epithelial ovarian cancer patients; and miR-205 is up-regulated in the epithelial ovarian cancer specimens. Ezrin and Lamin A/C are down-regulated in the epithelial ovarian cancer samples. VEGF, miR-205 and target protein may be associated with the invasion and metastasis of epithelial ovarian cancer.

In food systems, proteins and polyphenols typically coexist in a non-covalent manner. However, the inherent rigid structure of proteins may hinder the binding sites of polyphenols, thereby limiting the strength of their interaction. In the study, magnetic field (MF) treatment was used to enhance non-covalent interactions between coconut globulin (CG) and tannic acid (TA) to improve protein flexibility, enhancing their functional properties without causing oxidation of polyphenols. Based on protein structure results, the interaction between CG and TA caused protein structure to unfold, exposing hydrophobic groups. Treatment with a MF, particularly at 3 mT, further promoted protein unfolding, as evidenced by a decrease in α-helix structure and an increase in coil random. These structural transformations led to the exposure of the internal binding site bound to TA and strengthening the CG-TA interaction (polyphenol binding degree increased from 62.3 to 68.2%). The characterization of molecular forces indicated that MF treatment strengthened hydrogen bonding-dominated non-covalent interactions between CG and TA, leading to improved molecular flexibility of the protein. Specifically, at a MF treatment at 3 mT, CG-TA colloidal particles with small size and high surface hydrophobicity exhibited optimal interfacial activity and wettability (as evidenced by a three-phase contact angle of 89.0°). Consequently, CG-TA-stabilized high internal phase Pickering emulsions (HIPPEs) with uniform droplets and dense gel networks at 3 mT. Furthermore, the utilization of HIPPEs in 3D printing resulted in consistent geometric shapes, uniform surface textures, and distinct printed layers, demonstrating superior printing stability. As a result, MF treatment at 3 mT was identified as the most favorable. This research provides novel insights into how proteins and polyphenols interact, thereby enabling natural proteins to be utilized in a variety of food applications.

The fat in coconut milk contributes to unique flavour, while increasing fat content affects stability of the coconut milk. In this study, coconut water and fat were separated, recombined, and homogenized to obtain coconut milk with different fat contents (0-20 %). Emulsifying properties, stability, and digestibility of coconut milk with different fat contents were comprehensively evaluated. The results showed that as the fat content increased from 0 to 20 %, the droplet size increased from 2.18 to 4.70 µm and the viscosity showed an increasing trend. During storage and freeze-thaw, coconut milk with 5 % and 10 % fat content showed excellent stability. In addition, coconut milk with 10 % fat content had superior fat digestibility, which was related to high affinity of pancrelipase. In short, this study revealed that fat content below 10 % can withstand environmental factors such as storage, lipid oxidation, and freeze-thaw, which can be accurately developed as coconut milk products.

Metal-Organic Framework (MOF) membranes act as selective layers have offered unprecedented opportunities for energy-efficient and cost-effective gas separation. Searching for the green and sustainable synthesis method of dense MOF membrane has received huge attention in both academia and industry. In this work, we demonstrate an in situ electrochemical potential-induced synthesis strategy to aqueously fabricate Metal Azolate Framework-4 (MAF-4) membranes on polypropylene (PP) support. The constant potential can induce the heterogeneous nucleation and growth of MAF-4, resulting an ultrathin membrane with the thickness of only 390 nm. This high-quality membrane exhibits a high H2/CO2 separation performance with the H2 permeance as high as 1565.75 GPU and selectivity of 11.6. The deployment of this environment friendly one-step fabrication method under mild reaction conditions, such as low-cost polymer substrate, water instead of organic solvent, room temperature and ambient pressure shows great promise for the scale-up of MOF membranes.
RESUMO
Sorption-based atmospheric water-harvesting (AWH) could help to solve global freshwater scarcity. The search for adsorbents with high water-uptake capacity at low relative humidity, rapid adsorption-desorption kinetics and high thermal conductivity is a critical challenge in AWH. Herein, we report a MAF-4 (aka ZIF-8)-derived nanoporous carbon (NPCMAF-4-800) with multiple N-doped sites, considerable micropore characteristics and inherent photothermal properties, for efficient water production in a relatively arid climate. NPCMAF-4-800 exhibited optimal water-sorption performance of 306 mg g-1 at 40% relative humidity (RH). An excellent sunlight-absorption rate was realized (97%) attributed to its high degree of graphitization. A proof-of-concept device was designed and investigated for the practical harvesting of water from the atmosphere using natural sunlight. NPCMAF-4-800 achieved an unprecedentedly high water production rate of 380 mg g-1 h-1 at 40% RH, and could produce 1.77 L kg-1 freshwater during daylight hours in an outdoor low-humidity climate of â¼25 °C and 40% RH. These findings may shed light on the potential of MOF-derived porous carbons in the AWH field, and inspire the future development of solar-driven water-generation systems.
RESUMO
Critical evaluation of computational tools for predicting variant effects is important considering their increased use in disease diagnosis and driving molecular discoveries. In the sixth edition of the Critical Assessment of Genome Interpretation (CAGI) challenge, a dataset of 28 STK11 rare variants (27 missense, 1 single amino acid deletion), identified in primary non-small cell lung cancer biopsies, was experimentally assayed to characterize computational methods from four participating teams and five publicly available tools. Predictors demonstrated a high level of performance on key evaluation metrics, measuring correlation with the assay outputs and separating loss-of-function (LoF) variants from wildtype-like (WT-like) variants. The best participant model, 3Cnet, performed competitively with well-known tools. Unique to this challenge was that the functional data was generated with both biological and technical replicates, thus allowing the assessors to realistically establish maximum predictive performance based on experimental variability. Three out of the five publicly available tools and 3Cnet approached the performance of the assay replicates in separating LoF variants from WT-like variants. Surprisingly, REVEL, an often-used model, achieved a comparable correlation with the real-valued assay output as that seen for the experimental replicates. Performing variant interpretation by combining the new functional evidence with computational and population data evidence led to 16 new variants receiving a clinically actionable classification of likely pathogenic (LP) or likely benign (LB). Overall, the STK11 challenge highlights the utility of variant effect predictors in biomedical sciences and provides encouraging results for driving research in the field of computational genome interpretation.
RESUMO
OBJECTIVE: To explore the security, pregnancy outcomes, and the tumor recurrence related factors of young patients with cervical cancer treated with different radical trachelectomy (RT). METHODS: Thirty-two young patients < 40 years of age with early cervical cancer from May 2004 to July 2012 admitted in Tumor Hospital Xiangya School of Medicine of Central South University were divided into two groups based on different operation methods: vaginal radical trachelectomy (RVT) group and abdominal radical trachelectomy (RAT) group.The clinical data were analyzed by One-way Anova and multivariate Cox stepwise regression analysis. RESULTS: The operation duration, number of lymph node dissection, the height of the cervical resection, postoperative hospitalization time, incidence of vascular injury and incidence of postoperative lymphocele were respectively (250 ± 82) min, 15 ± 6, (2.31 ± 0.21) cm, (9.2 ± 2.9) d, 1/18 and 1/18 in RVT group, while (263 ± 60) min,16 ± 8, (2.32 ± 0.26) cm, (10.3 ± 3.5) d,0 and 1/14 in RAT group. There was no statistically significant difference between the two groups (all P > 0.05). The blood loss (281 ± 201) ml in RVT group was significantly lower than that in the RAT group (492 ± 320) ml (P < 0.05). The length of Vaginal hysterectomy [(2.61 ± 0.50) cm] and the width of parametrial resection [ (2.38 ± 0.36) cm] in RVT group were significantly less than those [(2.95 ± 0.10), (2.81 ± 0.22) cm] in the RAT group (all P < 0.05).The pregnancy rate between RVT group (3/18) and RAT group (2/14) were no significant difference (P > 0.05).One-way Anova analysis showed that the recurrence of early cervical cancer was related to tumor size in diameter (F = 4.911, P = 0.047), while there were no correlation with age, clinical stage, histological type and surgical approach (all P > 0.05).Multivariate analysis showed that tumor diameter size was an independent risk factor for tumor recurrence (ß = 0.259, P = 0.031). CONCLUSIONS: RT for young patients with early cervical cancer is feasible.Pregnancy outcomes after RT need to be study in the future. Tumor size in diameter is the major risk factor for tumor recurrence.

OBJECTIVE: To investigate the operative treatment for first-treated patients with malignant ovarian germ cell tumors who need preservation of fertility. METHODS: The clinical data of 105 patients who were treated with fertility-sparing surgery in 11 hospitals from 1992 to 2010 were collected to evaluate the outcomes of different primary surgical operative procedures. All 105 cases were performed the surgeries that preserved fertility and divided into three groups according to the surgical approaches, comprehensive staging surgery group: 47 cases (44.8%) received comprehensive staging surgeries that including the ipsilateral oophorectomy + omentectomy + retropertoneal lymph node dissection ± appendectomy + multiple biopsies;oophorectomy group:45 cases (42.9%)received ipsilateral oophorectomy ± biopsy of contralateral ovary ± omentectomy;tumor resection group:13 cases (12.4%) received enucleation of the mass with preservation of the ovary. Differences were compared among the three groups of patients in the surgery-related indicators, complications, fertility and prognosis. RESULTS: (1) Surgery-related indicators:the average blood loss of the comprehensive staging surgery group, the oophorectomy group and the tumor resection group were 496, 104 and 253 ml, the mean operation time were 176, 114 and 122 minutes, respectively, and there were significant differences among three groups (P = 0.011, P = 0.000). (2) Complication:the surgical complication rates of the three groups were 17% (8/47), 0 and 1/13, with significant differences (P = 0.015). (3) Reproductive function status: the pregnancy rate and birth rate of the three groups were no significant differences (9/19 vs. 7/19 vs. 2/3, P = 0.515; 8/19 vs. 5/19 vs. 2/3, P = 0.636). (4) PROGNOSIS: the recurrence rate of the three groups were significant differences [13% (6/47) vs. 0 vs. 2/13, P = 0.013], but the death rate with no significant differences [6% (3/47) vs. 0 vs. 0, P = 0.129]; The five-year survival rate of three different groups were 89%, 100% and 100% (P > 0.05), while disease free survival rate were 85%, 100% and 83% (P < 0.05), respectively. CONCLUSIONS: Compared with comprehensive staging surgery, oophorectomy group have higher surgical security and satisfactory prognosis, considerable pregnancy rates and birth rate. The tumor resection security may be reliable, but the prognosis is poor.

The Macau peninsula is close to the tropical ocean, with a high population density and a large number of high-rise buildings, which require a windy environment with good ventilation and heat dissipation. Based on residential samples and the degree of agglomeration, the high-rise residential area in Areia Preta was selected as the focus of this study. Meanwhile, summer typhoons pose serious safety risks to high-rise buildings. Therefore, it is necessary to study the connection between spatial form and the wind environment. First of all, this research is based on relevant concepts and the wind environment evaluation system of high-rise buildings and conducts research on high-rise residential areas in Areia Preta. PHOENICS software is used to simulate the prevailing monsoon in winter and summer, as well as a typhoon in an extreme wind environment, and summarize the wind environment's characteristics. Secondly, by comparing the parameter calculation and simulation results, the possible relationship between the causes of each wind field is studied. Finally, conclusions are drawn about the urban form and wind environment of the site, and corresponding control strategies are proposed to reduce the shielding effect between buildings and typhoon damage. It can be used as a theoretical basis and reference point for urban construction and high-rise building planning and layout.

Machine learning (ML) is an innovative method that is widely used in data prediction. Predicting the COVID-19 distribution using ML is essential for urban security risk assessment and governance. This study uses conditional generative adversarial network (CGAN) to construct a method to predict the COVID-19 hotspot distribution through urban texture and business formats and establishes a relationship between urban elements and COVID-19 so that machines can automatically predict the epidemic hotspots in cities. Taking Macau as an example, this method is used to determine the correlation between the urban texture and business hotspots of Macau and the new epidemic hotspot clusters. Different types of samples afforded different epidemic prediction accuracies. The results show the following: (1) CGAN can accurately predict the distribution area of COVID-19, and the accuracy can exceed 70%. (2) The results of predicting the COVID-19 distribution through urban texture and POI data of hospitals and stations are the best, with an accuracy of more than 60% in experiments in different regions of Macau. (3) The proposed method can also predict other areas in the city that may be at risk of COVID-19 and help urban epidemic prevention and control.
RESUMO
This paper takes the garden road system as the research object and proposes a method of generating paths for classical gardens based on parametric design. Firstly, by studying the distribution characteristics of roads, the data on the curvature, angle, and view area of roads were collected. Secondly, the obtained data were transferred to the parameterized platform, and a method of intelligent generation was used for calculation. Finally, the road system was optimized by the genetic algorithm for better application in modern landscape design. According to the current situation, the road system plan generated by the algorithm inherits the characteristics of classical garden roads. This method can be applied to the courtyard, the community park, the urban park, and other objects. This research not only identifies the characteristics of landscape cultural heritage, but also produces an innovative, intelligent design tool. It provides new methods for the parameterized inheritance and application of traditional landscape heritage.

Coconut milk is an unstable emulsion system, mainly stabilized by proteins, which limits the development of the food industry. The aim of this study was to investigate mechanisms for increasing emulsion stability through the interaction between coffee polyphenols (CPs) and coconut globulin (CG), the main protein in coconut milk. Caffeic acid (CA), chlorogenic acid (CHA), and ferulic acid (FA) were selected as CP models. The results showed that hydrogen bond interactions mainly occurred between CG and CPs (CG-FA < CG-CA < CG-CHA). CHA containing quinic acid preferentially formed a strong interaction with CG. The interaction changed the lipophilicity of CG and facilitated the formation of a dense and thick interfacial film at the oil-water interface. Furthermore, the emulsion stabilized by CG-CPs showed excellent stability after storage, centrifugation, pH, and salt treatment, especially CG-CHA. This study could provide a theoretical basis for improving the stability of coconut milk products.
