RESUMEN

Objective: To observe the changes of peri-implant tissue around the individualized abutment that was grinded from zirconia provisional crown in one year. Methods: In this research, a prosthodontic-driven virtual implant planning and immediate provisionalization were conducted in computer assisted design software. And computer-aided design/computer-aided manufacturing (CAD/CAM) techniques were used to fabricate the zirconia provisional crown and surgical guide template before surgery. The implant was accurately placed with the surgical guide, and the zirconia provisional crown was immediately delivered after surgery. Three months later, the implant osseointegration was completed, and zirconia provisional crown was prepared intraorally to generate customized zirconia abutment for final prosthesis. The study included 30 patients with single anterior tooth loss, including 18 males and 12 females, aged from 26 to 50 years old, and the mean age was (36.2±6.1) years old. The patients were from the Center of Oral Implantology, The First Affiliated Hospital of Zhejiang University Medical College from January 2017 to February 2018. After cementation of the final prosthesis, the cases were followed up at 6 and 12 months time intervals. Implant survival rate, probing depth, bleeding on probing, marginal bone level loss and papilla index score (PIS) were recorded in every appointment. Results: The survival rate of 30 implants was 100%, and the probing depths were less than 5 mm. The bone resorption at 6 and 12 months follow-up after the final delivery was 0 (0, 0) mm and 0 (-0.2, 0) mm, respectively, and the difference was not statistically significant (P>0.05). The PIS was 3.0 (2.0, 4.0), 3.0 (2.8, 4.0) and 3.0 (3.0, 4.0) on the final delivery, 6 and 12 months after final delivery, respectively. Conclusions: Marginal bone level and bone loss were stable with this new implant clinical protocol at the one-year follow-up.

RESUMEN

A female patient aged 42 years with deep burn on right lower limb was admitted to Affiliated Hospital of Jining Medical University on January 25, 2019. The patient previously had cerebral infarction, hypertension, and hysteria, with long-term use of aspirin and risperidone. After admission, the patient underwent tangential excision twice. On the third day after the second tangential excision and skin grafting, the muscle strength of the right limb gradually decreased, and the patient was treated with emergency craniocerebral magnetic resonance imaging, which suggested acute cerebral infarction. Improvement of cerebral circulation and vasodilatation were given immediately. The limb muscle strength of the patient gradually recovered on the fifth day after the operation, and no sequela was left when the patient was discharged. After the case was discussed, we think that postoperative decreased blood volume and blood concentration resulting from tangential excision bleeding of deep burn and wound exudate as well as inadequate fluid infusion are the main causes of hemodynamic change, the patient had the basis of multiple cerebral artery stenosis, and superposition of multiple factors led to the occurrence of postoperative acute cerebral infarction. Appropriate increase in the fluid infusion volume during and after surgery and transfusion if necessary to increase blood and oxygen supply to the brain can reduce the occurrence of cerebral infarction.

RESUMEN

Objective: To explore the feasibility of using faster regional convolutional neural network (Faster R-CNN) to evaluate the status of circumferential resection margin (CRM) of rectal cancer in the magnetic resonance imaging (MRI). Methods: This study was registered in the Chinese Clinical Trial Registry (ChiCTR-1800017410). Case inclusion criteria: (1) the positive area of CRM was located between the plane of the levator ani, anal canal and peritoneal reflection; (2) rectal malignancy was confirmed by electronic colonoscopy and histopathological examination; (3) positive CRM was confirmed by postoperative pathology or preoperative high-resolution MRI. Exclusion criteria: patients after neoadjuvant therapy, recurrent cancer after surgery, poor quality images, giant tumor with extensive necrosis and tissue degeneration, and rectal tissue construction changes in previous pelvic surgery. According to the above criteria, MRI plain scan images of 350 patients with rectal cancer and positive CRM in The Affiliated Hospital of Qingdao University from July 2016 to June 2019 were collected. The patients were classified by gender and tumor position, and randomly assigned to the training group (300 cases) and the validation group (50 cases) at a ratio of 6:1 by computer random number method. The CRM positive region was identified on the T2WI image using the LabelImg software. The identified training group images were used to iteratively train and optimize parameters of the Faster R-CNN model until the network converged to obtain the best deep learning model. The test set data were used to evaluate the recognition performance of the artificial intelligence platform. The selected indicators included accuracy, sensitivity, positive predictive value, receiver operating characteristic (ROC) curves, areas under the ROC curves (AUC), and the time taken to identify a single image. Results: The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of the CRM status determined by the trained Faster R-CNN artificial intelligence approach were 0.884, 0.857, 0.898, 0.807, and 0.926, respectively; the AUC was 0.934 (95% CI: 91.3% to 95.4%). The Faster R-CNN model's automatic recognition time for a single image was 0.2 s. Conclusion: The artificial intelligence model based on Faster R-CNN for the identification and segmentation of CRM-positive MRI images of rectal cancer is established, which can complete the risk assessment of CRM-positive areas caused by in-situ tumor invasion and has the application value of preliminary screening.

RESUMEN

OBJECTIVE: Esophageal squamous cell carcinoma (ESCC) is a common malignant epithelial tumor in the elderly, and the cause is very complicated. Therefore, the study of the pathogenesis of ESCC is conducive to the effective treatment of ESCC. Many studies indicated that lncRNAs were important regulatory factors in tumor formation and disease development. However, the regulatory network of lncRNA in ESCC has not been fully explored. MATERIALS AND METHODS: The expression of miR-574-3p, ZEB2-AS1, and HMGA2 was measured using qRT-PCR. The protein expression of PCNA, Cleaved-caspase3, MMP9, and HMGA2 was detected through Western blot. Cell proliferation or apoptosis of transfected cells was calculated via CKK-8 assay or flow cytometry. Transwell assay was applied to detect cell migration and invasion of ESCC cells. Luciferase reporter assay and RNA pull-down were used to determine the relationship among miR-574-3p, ZEB2-AS1, and HMGA2 in ESCC. Moreover, the regulatory network of ZEB2-AS1 has been verified in vivo in this study. RESULTS: We found that ZEB2-AS1 was upregulated in ESCC tissues and cells. The knockdown of ZEB2-AS1 could inhibit cell proliferation, invasion, and migration, as well as promoted cell apoptosis in ESCC. Interestingly, miR-574-3p deficiency or HMGA2 promotion could reverse the effects of si-ZEB2-AS1 on ESCC cell progression. Luciferase reporter assay indicated that miR-574-3p was a target miRNA of ZEB2-AS1 and HMGA2 was a target gene of miR-574-3p in ESCC. CONCLUSIONS: In this paper, we first verified the novel regulatory mechanism of lncRNA ZEB2-AS1 in ESCC cellular process. LncRNA ZEB2-AS1 promoted the proliferation, migration, and invasion of ESCC by modulating miR-574-3p/HMGA2 axis, indicating that ZEB2-AS1 played essential roles in cell progression in ESCC and providing a new therapeutic target of ESCC.

RESUMEN

OBJECTIVE: Triple-negative breast cancers (TNBC) are a subtype of breast cancer lacking of estrogen receptor (ER), progesterone receptor (PR), and human EGF-like receptor 2 (HER2). MiR-193 always acted as an oncogene and promoted toxic aldehyde accumulation and tyrosine hydroxylase dysfunction. The purpose of this study is to explore the function of miR-193 in triple-negative breast cancer. PATIENTS AND METHODS: Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was performed to examine the mRNA level of miR-193 expression in 50 cases of TNBC tissues and para-cancerous specimens. Also, the relation between miR-193 level and the overall survival of TNBC patient was analyzed. MiR-193 mimic and miR-193 inhibitor oligos, as well as the corresponding negative control, were synthesized from RiboBio (Guangzhou, China). RESULTS: MiR-193 expression was higher in triple-negative breast cancer tissues and cell lines than the corresponding adjacent non-tumor tissues and normal cell lines. Upregulation of miR-193 predicted poor prognosis of TNBC patients. Overexpression of miR-193 promoted cell proliferation and invasion, while that was suppressed by the knockdown of miR-193. MiR-193 binds to the 3'-UTR of an inhibitor of growth family member 5 (ING5) mRNA to mediate the expression of ING5 in TNBC cells. The knockdown of miR-193 inhibited cell invasion-mediated epithelial-mesenchymal transition (EMT). Furthermore, the knockdown of miR-193 suppressed cell proliferation through the ING5/phosphatidylinositol 3-hydroxy kinase/protein kinase B (PI3K/AKT) signal pathway. CONCLUSIONS: MiR-193 enhanced cell invasion-mediated EMT and improved cell proliferation through the ING5/PI3K/AKT signal pathway in triple-negative breast cancer. The newly identified miR-193/ING5/PI3K/AKT axis provides novel insight into the pathogenesis of triple-negative breast cancer.

RESUMEN

BACKGROUND: Wheat-dependent exercise-induced anaphylaxis (WDEIA) is a severe allergic condition in which wheat ingestion together followed by physical exercise induces anaphylaxis. For patients with WDEIA, omega-5 gliadin is considered to be one of the major allergens. AIM: To analyse the clinical features and allergen spectrum of WDEIA and to investigate the relationship between WDEIA and serum levels of platelet-activating factor (PAF), interleukin (IL)-9 and IL-33. METHODS: Medical histories and conditions of WDEIA cases were collected and summarized, with allergen tests of wheat proteins measured at the same visit. Of the 33 patients enrolled, 13 also had serum levels of PAF, IL-9 and IL-33 measured. The healthy control (HC) group consisted of 13 healthy individuals, who also underwent both the wheat-protein allergen tests and the inflammatory-mediator tests. RESULTS: All patients experienced severe allergic reaction during exercise after wheat ingestion. Manifestations of WDEIA included facial oedema, generalized urticaria and respiratory symptoms. Unconsciousness was also observed in 21 cases. In the patient group, 57.6% were confirmed as hypersensitive to glyceraldehyde-3-phosphate dehydrogenase (GAPDH), while 54.5% were allergic to omega-5 gliadin. PAF concentration was significantly higher in patients with WDEIA compared with HCs, whereas there was no significant difference in IL-9 or IL-33 between the two groups. CONCLUSIONS: WDEIA is a rare type of anaphylaxis. GAPDH and omega-5 gliadin may be the most common allergy-causing wheat proteins for Chinese people. PAF may be associated with the onset and development of WDEIA.

RESUMEN

OBJECTIVE: Some circular RNAs (circRNAs) have been testified to play crucial roles in the regulation of skin melanoma, including circRNA_0016418 (circ0016418). However, the regulatory mechanism of circ0016418 in skin melanoma is undiscovered. MATERIALS AND METHODS: The RNA expression was examined through quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) and associated-proteins levels were measured via Western blot. Cell counting kit-8 (CCK-8) assay was used for detecting cell proliferation. Transwell assay was conducted to assess the abilities of migration and invasion. The target relation was analyzed by Dual-Luciferase reporter assay. RESULTS: The levels of circ0016418 and Yin Yang 1 (YY1) were up-regulated in skin melanoma tissues and cells. Knockdown of both circ0016418 and YY1 had suppressive effects on proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT) of skin melanoma cells. YY1 overexpression reverted the inhibitory effects on skin melanoma cells caused by circ0016418 knockdown. Circ0016418 negatively modulated microRNA-625 (miR-625) expression and miR-625 directly targeted YY1. Circ0016418 functioned as a competitive endogenous RNA (ceRNA) of miR-625 to regulate YY1 expression. CONCLUSIONS: Circ0016418 regulated proliferation, migration, invasion, and EMT of skin melanoma cells through miR-625/YY1 axis. Circ0016418 might be a useful indicator of the therapeutic strategies of skin melanoma.

RESUMEN

Objective: To investigate the diagnosis of normal cornea, subclinical keratoconus and keratoconus by artifical intelligence. Methods: Diagnostic study. From January 2016 to January 2019, who admitted to Tianjin Eye Hospital from 18 to 48 years old, with an average of (28.4±8.2) years of myopia patients in 2 018 cases. Two experienced ophthalmologists labeled keratoconus, subclinical keratconus and nomal cornea based on the topography. The data of 80% (1 615 cases) patients were randomly selected as the training set by computer random sampling method, and the data of 20% (403 cases) patients were used as the verification set. Using the Gradient Boosting Decision Tree (GBDT) algorithm to extract 28 corneal parameters, and establish an algorithm model to diagnose the corneal condition of the patient, verify the diagnostic accuracy of the model by using the 10-fold cross-validation method, and evaluate the model using the receiver operating characteristic curve. Sensitivity and specificity with the original labeling and ophthalmic resident labeling. Results: The diagnostic accuracy of the model was 95.53%. The area under the receiver operating characteristic curve (AUC) of the validation set was 0.996 6. The accuracy of the model for diagnosis of subclinical keratoconus and normal cornea was 96.67%, the AUC of the validation set was 0.993 6; the accuracy of diagnosis of keratoconus and normal cornea was 98.91%, and the AUC of the validation set was 0.998 2. The diagnostic accuracy of the model is 95.53%, which is significantly better than the resident's 93.55%. Conclusion: The model established by artifical intelligence can diagnose the subclinical keratoconus with high accuracy, which can greatly improve the clinical diagnosis efficiency and accuracy of young and primary ophthalmologists.

RESUMEN

Objective: To explore the change of hypothalamic-pituitary-thyroid axis hormones and it's role in depression in obstructive sleep apnea-hypopnea syndrome. Methods: Seventy-three male OSAHS patients [age (39±11) years] and 13 male controls [age (36±7.5) years] were enrolled from August 2013 to May 2017 in the 1(st) Hospital of China Medical University. Overnight polysomnography and depression were assessed. The serum TRH, TSH, FT4 and FT3 levels were measured on the next morning. The relationship between depression and hypothalamic-pituitary-thyroid axis was analyzed. Results: Compared with the control group, severe hypoxia group had higher serum FT3 level [(4.5±0.6) ng/L vs. (5.4±0.7)ng/L, P<0.05)] and depression score (30±7 vs. 40±10, P<0.05). Further analysis revealed that serum FT3 level (5.0±0.5 ng/L vs. 5.5±0.7ng/L, P<0.05) and FT4 level [(16.2±1.9) ng/L vs. (18.2±2.3) ng/L, P<0.05] were lower in the patients with depression than those without. Conclusion: The decrease of serum FT3 and FT4 levels in OSAHS patients with severe hypoxia was closely related to the occurrence of depression.

RESUMEN

Objective: To investigate the effects of chronic intermittent hypoxia on somatotropic axis hormone levels in rats. Methods: Mature male Wistar rats were exposed to air or intermittent hypoxia randomly.The serum levels of growth hormone-releasing hormone (GHRH), growth hormone (GH) and somatostatin (SS) were measured before exposure, at the 4th, 8th, and 12th week after exposure. Different hormone levels in two groups were compared and analyzed. Results: Compared with the control group, GHRH levels in chronic intermittent hypoxic group showed a significant decline at the 4th week [(732.77±46.99)pg/ml vs. (893.59±40.00) pg/ml, P<0.05], while SS levels at the 8th week [(30.71±2.27) pg/ml vs. (44.69±3.36) pg/ml, P<0.05] and GH levels at the 12th week [(1.20±0.29) ng/ml vs. (2.06±0.13) ng/ml, P<0.05] were similarly reduced. As the duration of intermittent hypoxia was prolonged, the GHRH levels did not decrease further [4th week (732.77±46.99) pg/ml vs. 8th week (607.54±131.61) pg/ml vs. 12th week (730.05±40.63) pg/ml, P>0.05].However, the serum SS levels decreased further from the 8th week to the 12th week [(30.71±2.27) pg/ml vs. (24.41±4.06) pg/ml, P<0.05]. Conclusion: Chronic intermittent hypoxia might inhibit the function of somatotropic axis. Hypothalamic hormones are the earlyonesto be influenced, thereafter the entire axis.

RESUMEN

OBJECTIVE: Accumulating evidence showed that dysregulation of cyclin-dependent kinases regulatory subunit 2 (CKS2) could contribute to tumor growth and metastasis of several tumors. However, its expression and function in epithelial ovarian cancer (EOC) have not been investigated. Here, we aimed to investigate the role of CKS2 in EOC. PATIENTS AND METHODS: Real-time PCR and Western blotting were used to determine the mRNA and protein expression of CKS2 in EOC tissues and cell lines. Then, the associations of CKS2 expression with clinicopathological features and patient's overall survival were determined. Proliferation assay flow cytometric analysis and transwell assay were performed to detect the relation between CKS2 and malignant behaviors of EOC cells. We also evaluated the expression of related proteins of the Akt/mTOR pathway to determine the associated molecular mechanism. RESULTS: We found that CKS2 expression was significantly up-regulated in both EOC tissues and cell lines. Clinically, high expression of CKS2 was associated with advanced FIGO stage, histological grade and shorter overall survival of EOC patients. We also found that knockdown of CKS2 suppressed proliferation, invasion, and migration of EOC cells in vitro, and CKS2 could promote EMT progress by modulating EMT-related molecules. Finally, Western blot demonstrated that down-regulation of CKS2 suppressed the expression of p-Akt and p-mTOR. CONCLUSIONS: Our findings indicated that CKS2 might function as a tumor promoter by modulating Akt/mTOR pathway in EOC and could serve as a promising prognostic biomarker for EOC.

RESUMEN

The aim of this study was to investigate the mechanism of hepatocyte apoptosis and regeneration after partial hepatectomy in obstructive jaundice (OJ) rats under different drainage methods of bile acid intervention. Forty male Sprague Dawley rats were randomly divided into five groups. An OJ rat model was established by the following protocols. Seven days after obstruction, an SD rats model with 70% partial hepatectomy was established by different drainage methods of OJ. Blood and liver tissue samples were collected from rats 72 h after surgery; 72 h after partial hepatectomy (PH), the liver regeneration rate, the expression of proliferating cell nuclear antigen (PCNA) and the level of mitotic index (MI) in the internal biliary drainage (IBD) group were higher than those in external biliary drainage (EBD) group (P less than 0.05). Those in the EBD group were higher compared to the OJ group (P less than 0.05). There was no significant difference among the IBD group, EBD+CA group and (SO) sham operation group (P>0.05). Bax expressions had the same trend as AI in the five groups. The expression of Bcl-2 was increased in the IBD group and EBD+CA group, which was statistically higher compared to the SO group (P less than 0.05). In conclusion, both internal and external drainage can relieve biliary obstruction. The difference in liver regeneration caused by external drainage and internal drainage may be attributed to the destruction of bile acid enterohepatic circulation, which increases hepatocyte apoptosis and affects liver regeneration.

RESUMEN

BACKGROUND: Methotrexate (MTX) is an efficacious treatment for psoriasis; however, its widespread application is limited by its unpredictable efficacy. OBJECTIVES: To investigate the association of clinical factors and variants of psoriasis susceptibility genes with clinical responses to MTX in a prospective cohort. METHODS: A total of 221 patients with psoriasis were recruited. Patients who achieved Psoriasis Area and Severity Index (PASI) improvement ≥ 75% at week 12 were defined as responders, whereas those with PASI improvement < 50% were defined as nonresponders. In 90 screening patients, genetic variants for 18 single-nucleotide polymorphisms in 14 susceptibility genes, and HLA-Cw6 status were initially compared for responders and nonresponders. Statistically significant associations in genetic variants were verified in all 221 patients. RESULTS: Overall, 49% and 45% of patients achieved PASI 75 improvement during screening and verification stages, respectively. Concomitant arthritis with psoriasis and high body mass index (BMI) negatively affect the efficacy of MTX. TT genotype of rs10036748 in TNIP1 was significantly associated with PASI 75 response at week 12 (54% and 37%, P < 0·05). A significantly higher PASI 90 response was observed in patients with TT genotype of rs10036748 (27% vs. 12%, P < 0·01) and TC/TT genotype of rs4112788 in LCE3D (25% vs. 13%, P < 0·05) at week 12 compared with those who had other genotypes. After adjustment for all confounding factors, only BMI (P < 0·05), arthritis (P < 0·05) and genotype of rs10036748 (P < 0·05) were significantly associated with clinical responses to MTX. CONCLUSIONS: Patients with psoriasis with TT genotype of rs10036748 in TNIP1, with lower BMI, without arthritis will achieve a better response to MTX.

RESUMEN

Objective: To explore the factors that contribute to the anxiety and depression in obstructive sleep apnea hypopnea syndrome (OSAHS) patients in terms of excessive daytime sleepiness (EDS) and sleep quality. Methods: A total of 196 OSAHS patients, including 103 severe patients and 93 mild-moderate patients, were enrolled. Polysomnography was carried on at the sleep center of the First Hospital of China Medical University between May 2013 and November 2015. According to the Epworth sleepiness scale (ESS) and the subject daytime sleepiness symptom, all patients were divided into EDS group and non-EDS group. The patients' general information and subjective symptoms were recorded. Emotional states were assessed with self-rating anxiety scale (SAS) and self-rating depression scale (SDS). Sleep quality was evaluated with Pittsburgh sleep quality index (PSQI). The anxiety and depression related factors were studied by regression analysis. Results: (1) In severe OSAHS group, the patients with EDS showed higher PSQI(6.22±2.57 vs. 4.05±3.72, P<0.01) and oxygen desaturation index(ODI)[(57.70±17.53) events/h vs. (48.23±22.01) events/h, P<0.05] when compared with those without EDS. (2) In both severe and mild-moderate OSAHS groups, the patients with EDS presented higher SAS scores (severe: 33.86±7.60 vs.28.95±4.71, mild-moderate: 37.46±10.68 vs. 33.40±11.07, P<0.05) and SDS scores (severe: 32.81±8.36 vs. 28.90±4.53, mild-moderate:36.98±12.77 vs. 31.70±10.94, P<0.05) when compared with those without EDS. (3) The multiple regression analysis showed that the SAS scores were related to ESS, PSQI, insomnia and nasal obstruction (R(2)=0.356, P<0.05), and the SDS scores were related to ESS, PSQI and insomnia(R(2)=0.344, P<0.05). Conclusions: The anxiety and depression of OSAHS patients are closely related to the severity of EDS and sleep quality. Both severe and mild-moderate OSAHS patients with EDS have worse anxiety and depression scores.

RESUMEN

Liver cirrhosis is the end stage of a variety of chronic liver diseases. In recent years, a number of clinical studies related to cirrhosis have provided new evidence for natural history of cirrhosis, etiologic treatment and management of complications. The present article evaluates the cirrhosis-related articles in this issue and summarizes the advances of cirrhosis staging, antiviral therapy in patients with decompensated hepatitis C cirrhosis, drug treatment of portal hypertension, terlipressin in the treatment of cirrhotic ascites, and the management of portal vein thrombosis. The unmet needs in cirrhosis-related clinical studies are also discussed.

RESUMEN

Cereal grains treated with organic acids were proved to increase ruminal resistant starch and can relieve the risk of ruminal acidosis. However, previous study mainly focussed on acid-treated barley, the effects of organic acid-treated corn is still unknown. The objectives of this study were to evaluate whether feeding ground corn steeped in citric acid (CA) would affect ruminal pH and fermentation patterns, milk production and innate immunity responses in dairy goats. Eight ruminally cannulated Saanen dairy goats were used in a crossover designed experiment. Each experimental period was 21 day long including 14 days for adaption to new diet and 7 days for sampling and data collection. The goats were fed high-grain diet contained 30% hay and 70% corn-based concentrate. The corn was steeped either in water (control) or in 0.5% (wt/vol) CA solution for 48 h. Goats fed CA diet showed improved ruminal pH status with greater mean and minimum ruminal pH, and shorter (P<0.05) duration of ruminal pH<5.6 and less area of ruminal pH<5.6, 5.8 and 6.0. Concentration of total volatile fatty acid and molar proportion of propionate were less but the molar proportion of acetate was greater (P<0.05) in goats fed the CA diet than the control diet. Concentration of ruminal lipopolysaccharide (LPS) was lower (P<0.05) and that of lactic acid also tended (P<0.10) to be lower in goats fed CA than the control. Although dry matter intake, actual milk yield, yield and content of milk protein and lactose were not affected, the milk fat content and 4% fat-corrected milk tended (P<0.10) to be greater in goats fed CA diet. For the inflammatory responses, peripheral LPS did not differ, whereas the concentration of LPS binding protein and serum amyloid A tended (P<0.10) to be less in goats fed CA diet. Similarly, goats fed CA diet had less (P<0.05) concentration of haptoglobin and tumour necrosis factor. These results indicated that feeding ground corn treated with CA effectively improved ruminal pH status, thus alleviated the risk of ruminal acidosis, reduced inflammatory response, and tend to improve milk yield and milk fat test.

RESUMEN

Objective: To investigate the value of tumor perfusion parameter measured by using double contrast-enhanced ultrasound (DCEUS) QontraXt three-dimensional pseudocolor quantitative analysis to the therapeutic effect evaluation of preoperative neoadjuvant chemotherapy (NAC) in advanced gastric cancer (AGC) patients. Methods: Eighty-nine AGC patients underwent 3 cycles of preoperative NAC (XELOX) followed by complete resection of lesion. The DCEUS QontraXt three-dimensional pseudocolor was performed one or two weeks before the NAC and operation were applied, respectively. The peak enhancement (PE), time to peak (TP), sharpness of the bolus (ß) and area under the enhancement curve (AUC) of primary gastric tumor were measured by QontraXt three-dimensional pseudocolor quantitative analysis. These DCEUS parameters between respond and non-respond groups before and after NAC therapy were compared. The prediction accuracy of DCEUS to the therapeutic effect evaluation of preoperative NAC was determined by the receive operating characteristic (ROC) curves. Results: Among 89 AGC patients, 52 patients responded to NAC therapy, while 37 patients resisted to NAC therapy. Twelve cases in respond group and 26 cases in non-respond group were mucinous carcinoma. Forty cases in respond group and 11 cases in non-respond group were non-mucinous carcinoma (P<0.05). In responder group, the PE and TP before NAC were (53.7±9.3)% and (14 521±2 667) ms, and (32.2±5.5)% and (17 235±1 898) ms after NAC. The ratio of changes of PE (ΔPE) and TP (ΔTP) were 0.43±0.17 and 0.36±0.14, respectively. In non-respond group, the PE and TP before NAC were (54.4±7.2)% and (13 869±3 247) ms, and (45.3±6.1)% and (15 127±1 423) ms after NAC therapy. The ratio of ΔPE and ΔTP were 0.24±0.20 and 0.22±0.12. The PE and TP after NAC, the ratio of ΔPE and ΔTP were significant different among these two groups (all of P<0.05). The ROC curves showed that the ratio of ΔPE in assessing the respond of gastric cancer patients to NAC was superior compared to other parameters (AUC=0.784, P=0.004). The optimal cut-off value of the ratio of ΔPE was 24% and its sensitivity and specificity to the therapeutic effect evaluation of NAC in gastric cancer were 82.7% and 64.9%. Conclusion: DCEUS QontraXt three-dimensional pseudocolor quantitative analysis might be a novel, noninvasive and reliable method to evaluate the therapeutic effect of preoperative NAC in AGC patients.
