The dismal outcome in patients with locally advanced or metastatic gastric cancer (GC) highlights the need for effective systemic neoadjuvant chemotherapy to improve clinical results. This study evaluated the correlation between the expression of three DNA repair genes, namely the excision repair cross-complementing group 1 (ERCC1), excision repair cross-complementing group 2 (ERCC2), and X-ray repair cross-complementing protein 1 (XRCC1) and the clinical outcome of patients with locally advanced or metastatic GC treated with mFOLFOX-4 neoadjuvant chemotherapy. Fifty-eight patients with histologically confirmed locally advanced or metastatic GC following neoadjuvant mFOLFOX-4 chemotherapy were enrolled between January 2009 and January 2018. We analyzed clinicopathological features and ERCC1, ERCC2, and XRCC1 expression to identify potential predictors of clinical response. Among the 58 patients, 16 (27.6%) were categorized into the response group (partial response) and 42 into the nonresponse group (stable disease in 24 patients and progressive disease in 18 patients). A multivariate analysis showed that ERCC1 overexpression (P = 0.003), ERCC2 overexpression (P = 0.049), and either ERCC1 or ERCC2 overexpression (P = 0.002) were independent predictors of response following mFOLFOX-4 neoadjuvant chemotherapy. Additionally, ERCC1 and ERCC2 overexpression did not only predict the response but also progression-free survival (both P < 0.05) and overall survival (both P < 0.05). ERCC1 and ERCC2 overexpression are promising predictive biomarkers for patients with locally advanced or metastatic GC receiving neoadjuvant mFOLFOX-4 chemotherapy and the potential clinical implication is mandatory for further investigation.

Introduction Proton pump inhibitors (PPIs) and histamine receptor 2 (H2) antagonists are commonly prescribed medications. Association between PPIs and alteration of the gut microbiota has been reported. Blastocystis, the most common intestinal protozoan worldwide, occurs in both healthy and symptomatic people with gastrointestinal or cutaneous disorders, with controversial pathogenicity. The current study was aimed to investigate the influence of PPIs and H2 blockers on the in vitro proliferation of selected intestinal bacteria, fungi, and protozoa. Methods Cultures of Lactobacillus rhamnosus, Escherichia coli, Enterococcus faecium, Candida albicans, and Blastocystis subtype 3 were treated with different concentrations of respective medications in vitro, and the numbers of microorganisms were quantified and compared. Results Pantoprazole and esomeprazole exerted a significant inhibition on Blastocystis and C. albicans, especially at higher concentrations, which were even more effective than metronidazole. On the other hand, treatment with pantoprazole caused an increase in proliferation of L. rhamnosus and E. coli. There was no influence of H2 blockers on the examined microorganisms. Discussion PPIs, such as pantoprazole, can be a potential treatment in the prophylaxis or eradication of Blastocystis and C. albicans.

In traditional processing, a large number of G01 blocks are adopted to discretize free surface or curve for NC machining. But, the continuity of G01 line segments is only C0, which may lead to discontinuity of axis acceleration, resulting in the frequent fluctuation of tool motion at the junctions in high-speed machining, deteriorating the quality of work piece, and reducing processing efficiency. To solve this problem, a local smoothing interpolation method is proposed in this paper. At first, the analytic relationship between the continuity of the trajectory and the continuity of the axes motion is first systematically described by formula. Based on this relationship, a local smoothing algorithm and a feed-rate scheduling method are proposed to generate a C2 continuous tool path motion with axis-acceleration continuity. The local smoothing algorithm smoothes the corners of G01 blocks by the cubic B-spline according to the cornering error tolerance specified by the user. After the feed rate at critical points of smoothed tool path was determined by a modified bidirectional scanning algorithm by considering constrains of chord error and kinematic property, an iterative S-shape feed rate scheduling is employed to minimize residual distance caused by round of time while ensuring the continuity of feed rate and acceleration. Then, a look-ahead interpolation strategy combined with smoothing algorithm and feed-rate scheduling as mentioned is proposed for real-time interpolation of short line segments. At last, simulations are conducted to verify the effectiveness of the proposed methods. Compared with the traditional G01 interpolation, it can significantly improve the processing efficiency and shorten the processing time within error tolerance.

Cigarette smoking is a well-known risk factor of upper digestive diseases. Findings on alcohol's effect on these diseases are inconsistent and with the exception of its association with esophageal cancer, little is known about betel quid chewing. This study investigated the association between use of these three substances and upper digestive diseases. We collected data from 9,275 patients receiving upper endoscopies between April 2008 and December 2013. Polynomial regressions were used to analyze the association between risk factors and diseases of the esophagus, stomach and duodenum. Meta-analysis for use of these substances and esophageal diseases was also performed. Participants who simultaneously consumed cigarettes, alcohol and betel quid had a 17.28-fold risk of esophageal cancer (95% CI = 7.59–39.33), 2.99-fold risk of Barrette's esophagus (95% CI = 2.40–4.39), 1.60-fold risk of grade A-B erosive esophagitis (95% CI = 1.29–2.00), 2.00-fold risk of gastric ulcer (95% CI = 1.52–2.63), 2.12-fold risk of duodenitis (95% CI = 1.55–2.89) and 1.29-fold risk of duodenal ulcer (95% CI = 1.01–1.65). Concurrent consumption of more substances was associated with significantly higher risk of developing these diseases. Meta-analysis also revealed use of the three substances came with a high risk of esophageal diseases. In conclusions, cigarette smoking, alcohol drinking and betel quid chewing were associated with upper digestive tract diseases.

Products in the stamping industry have been widely used in 3C products (computers, communications, and consumer electronics), daily necessities, and transportation vehicles. With the rapid development of the manufacturing industry and the rising cost of traditional methods of production, labor, equipment, and materials, it is essential to invest in automated production equipment. Therefore, improvements in stamping equipment with automated feeding to increase production capacity have been valued and adopted by enterprises. Manufacturers have also invested in the development and production of stamping equipment. The main purpose of this study is to improve the stamping process to reduce labor and increase production capacity. First, a 3D feeding manipulator is simulated. Its control system adopts a programmable logic controller with a motion control module, which is then connected to a servo unit via Mechatrolink-III onsite network communication. An electronic cam synchronous tracking function is used to control the trajectory between the manipulator and the punch and reduce the punch's waiting time for the displacement of the manual parts of the feeding machine, thereby increasing the production efficiency. The control system is matched with a human-machine interface, which makes it easier to operate, test the mold, set the cam curve, and troubleshoot. Thus, product quality and production capacity can be significantly improved. [ABSTRACT FROM AUTHOR]

This paper explores the mechanism design of a balloon machine representing a vending machine where consumers can select their desired shapes, as well as avoid bursting caused by manual inflation. Inside the machine, balloons are placed on the mechanism designed based on a waterwheel which rotates at a constant speed generated by motion among different sizes of gears. When rotating to the corresponding shaped balloon, the inflator will move under the opening to pull it out from the display point and start to inflate the balloon for the set number of seconds. After the inflation is completed, the glass door will open and the customer can take out their balloon. The main purpose of our development and design of the balloon machine is to improve the general balloon blowing and it is easy to prevent over-exposure and blast. The balloon machine can automatically inflate and detect the blowing time to improve the shortcomings of the balloon’s blast. In this way, it can effectively decrease sudden explosions and the number of frightened people.

Style transfer of polyphonic music recordings is a challenging task when considering the modeling of diverse, imaginative, and reasonable music pieces in the style different from their original one. To achieve this, learning stable multi-modal representations for both domain-variant (i.e., style) and domaininvariant (i.e., content) information of music in an unsupervised manner is critical. In this paper, we propose an unsupervised music style transfer method without the need for parallel data. Besides, to characterize the multi-modal distribution of music pieces, we employ the Multi-modal Unsupervised Image-to-Image Translation (MUNIT) framework in the proposed system. This allows one to generate diverse outputs from the learned latent distributions representing contents and styles. Moreover, to better capture the granularity of sound, such as the perceptual dimensions of timbre and the nuance in instrument-specific performance, cognitively plausible features including mel-frequency cepstral coefficients (MFCC), spectral difference, and spectral envelope, are combined with the widely-used mel-spectrogram into a timbreenhanced multi-channel input representation. The Relativistic average Generative Adversarial Networks (RaGAN) is also utilized to achieve fast convergence and high stability. We conduct experiments on bilateral style transfer tasks among three different genres, namely piano solo, guitar solo, and string quartet. Results demonstrate the advantages of the proposed method in music style transfer with improved sound quality and in allowing users to manipulate the output.

BACKGROUND Culture of Helicobacter pylori with previous eradication failure has been emphasized in clinical guidelines. The current unmet need to manage previously treated H pylori is one tool with diagnostic accuracy and ability for antibiotics susceptibility. Gastric juice PCR can provide diagnosis and antibiotics susceptibility; however, whether treatment failure affects its accuracy remains uninvestigated. Our study aimed to investigate diagnostic accuracy and antibiotics susceptibility of juice PCR in previously treated H pylori and to compare with the current standard of culture. METHODS We categorized all 547 patients into treatment-naive, post-1st treatment, post-2nd treatment, and post-3rd treatment. Helicobacter pylori infection was confirmed using gold standards. Sensitivity, specificity, positive predictive value, negative predictive value, receiver operating characteristic (ROC) curve and area under ROC curve (AUC) of juice PCR and culture were calculated. Intra-gastric H pylori density was evaluated. Lastly, the antibiotics susceptibility results of gastric juice and culture were compared. RESULTS Our findings demonstrated AUC was higher in juice PCR than culture in all patients (96.7% vs 91.3%, P

Background and aim Asian populations have relatively lower prevalence of gastroesophageal reflux disease and tend to exhibit symptoms of prolonged gastric retention. However, it remains unknown if slower gastric emptying influences its features in Asian countries. We prospectively assessed the potential implications of slower gastric emptying in an Asian-Pacific cohort of gastroesophageal reflux disease by a hospital-based survey. Methods One hundred fifty-two patients of gastroesophageal reflux disease complete the scintigraphic measurement of solid phase of gastric emptying. Clinical symptoms and psychological stress are recorded by self-report questionnaire. The status of Helicobacter pylori infection, blood level of pepsinogen I, and I/II ratio are assessed. Results Forty-seven percent and 28% of the patients have slower gastric emptying rate, depending on the incremental defined cut-off values of slower gastric emptying, respectively. Multiple logistic regression analysis indicates that older age and depression score are independently related to slower gastric emptying. Subgroup analysis discloses that patients with slower gastric emptying and higher depression score tend to present with non-erosive esophagitis whereas higher body mass index level and male gender in patients with normal gastric emptying predict the presence of erosive reflux disease. Conclusions Our study cohort of Asian patients indicates distinctive clinical implications of slower gastric emptying in patients with gastroesophageal reflux disease.

Epidemiologic data show the incidence of gastric cancer in men is twofold higher than in women worldwide. Oestrogen is reported to have the capacity against gastric cancer development. Endogenous oestrogen reduces gastric cancer incidence in women. Cancer patients treated with oestrogens have a lower subsequent risk of gastric cancer. Accumulating studies report that bone marrow mesenchymal stem cells (BMMSCs) might contribute to the progression of gastric cancer through paracrine effect of soluble factors. Here, we further explore the effect of oestrogen on BMMSCs‐mediated human gastric cancer invasive motility. We founded that HBMMSCs notably secrete interleukin‐8 (IL‐8) protein. Administration of IL‐8 specific neutralizing antibody significantly inhibits HBMMSCs‐mediated gastric cancer motility. Treatment of recombinant IL‐8 soluble protein confirmed the role of IL‐8 in mediating HBMMSCs‐up‐regulated cell motility. IL‐8 up‐regulates motility activity through Src signalling pathway in human gastric cancer. We further observed that 17β ‐estradiol inhibit HBMMSCS‐induced cell motility via suppressing activation of IL8‐Src signalling in human gastric cancer cells. 17β‐estradiol inhibits IL8‐up‐regulated Src downstream target proteins including p‐Cas, p‐paxillin, p‐ERK1/2, p‐JNK1/2, MMP9, tPA and uPA. These results suggest that 17β‐estradiol significantly inhibits HBMMSCS‐induced invasive motility through suppressing IL8‐Src signalling axis in human gastric cancer cells.

PURPOSE: This study aimed to identify the efficacy and toxicity of the FOLFIRI regimen (fluorouracil, leucovorin, and irinotecan) with irinotecan dose escalation plus bevacizumab as first-line chemotherapy for metastatic colorectal cancer (mCRC) via UGT1A1 genotyping. METHODS: We administered bevacizumab plus FOLFIRI with irinotecan dose escalation to treat 70 mCRC patients. The UGT1A1 *1/*1 and *1/*28 genotypes started with a 180-mg/m2 dose of irinotecan, and UGT1A1 *28/*28 genotype started with a dose of 120 mg/m2. The dose of irinotecan was escalated at increasing intervals of 20 to 30 mg/m2 until grade 3/4 adverse events (AEs) occurred. The clinical response rate, toxicity, and survival were analyzed. RESULTS: The clinical response and disease control rates of mCRC patients treated with FOLFIRI plus bevacizumab were significantly better in patients with UGT1A1 *1/*1 and *1/*28 genotypes than in patients with UGT1A1 *28/*28 (P = .006 and P < .001, respectively). Grade 3/4 AEs were significantly more common in mCRC patients with the UGT1A1 *28/*28 genotype (P < .001). Progression-free survival was significantly higher in UGT1A1 *1/*1 and *1/*28 patients (P = .002). mCRC patients who underwent metastasectomy achieved better overall survival than those who did not undergo metastasectomy (P = .015). CONCLUSIONS: Our study showed that mCRC patients with UGT1A1 *1/*1 and *1/*28 genotypes could receive escalated doses of irinotecan to obtain a more favorable clinical outcome without significant AEs.

The aim of this study is to design and establish a long-term care management system with the functions of data acquisition, data access, and website management for a long-term care center, along with the utilization of an Internet of Things (IoT) demo board and router to transmit the measurement parameters of biomedical sensor modules to the server database, including blood pressure, body temperature, and heart rate modules, for physiological information measurement by the system. The interface for information browsing is simple and user-friendly. This system uses Windows 10 as its operating system and uses Apache to create a Hypertext Transfer Protocol (HTTP) server, as well as the MySQL relational database management system and WordPress.com blog services. WordPress.com is also utilized to design a web interface so that the family of the person in long-term care can instantly access their physiological information, and the hierarchical webpage architecture enables administrators to manage the information regarding long-term care. The blog format allows users to operate it easily, and the physiological data and website information are stored in the MySQL system. Message Queuing Telemetry Transport (MQTT) protocol was designed by using Microsoft Visual C# to store the data in the database with the application programs to implement the transmission function for the physiological data. A WeMos D1 demo board is utilized to implement the data publish function for heart rate, body temperature, and blood pressure via the MQTT protocol. The advantage of this system is that it is based on the IoT structure, and the biomedical measurement data can be managed via the website with security, privacy, wear ability, and low-power operation. Moreover, an alarm function is also implemented to help medical staff manage measurement data and achieve the goal of instant care. [ABSTRACT FROM AUTHOR]

The aim of this study is to use the Internet of Things (IoT) for data monitoring of powered wheelchairs, which is divided into monitoring the position, tire wear, and battery charge level. Our system can be divided into two parts: Arduino UNO (an open-source microcontroller board; the word "uno" means "one" in Italian) and Raspberry Pi. Arduino UNO combines radio frequency identification (RFID) to read Electronic Product Code (EPC) tag information to establish the position information of powered wheelchairs. Raspberry Pi, through cooperation with the Quantum Geographic Information System (QGIS), establishes a coordinate activity map and monitors the tire wear of the powered wheelchair at any time, and uses a DC100 V LED dual display digital voltage meter head and external shunt to detect the lead-acid battery charge level of the powered wheelchair. Finally, a Microsoft Excel macro and Excel Visual Basic for Applications (VBA) are used to integrate the EPC tag information, tire wear, and lead-acid battery power consumption data and display them as real-time dynamic charts. The user can know the status of the wheelchair at any time, the user's family can also know the operation status of an elderly user or one with limited mobility, and the user is informed in advance when the wheelchair needs to be adjusted.

Here we report a case of metastatic colon cancer treated with 5-fluorouracil, leucovorin, and escalated doses of irinotecan (FOLFIRI) combined with regorafenib in the fourth-line setting after uridine diphosphate glucuronosyltransferase (UGT)1A1 genotyping analysis. A 66-year-old male was initially diagnosed with Union Internationale Contre le Cancer stage III descending colon cancer and underwent curative surgery. He received postoperative adjuvant chemotherapy; however, liver metastasis developed and a partial hepatectomy was performed thereafter. Unfortunately, pulmonary metastases and recurrent liver tumors were found despite a series of systemic treatments with multiple combinations of cytotoxic and biologic agents. Recently, a novel multikinase inhibitor, regorafenib, was approved for the treatment of metastatic colorectal cancer refractory to other therapeutic modalities. As further treatment, we combined regorafenib with FOLFIRI, which included dose escalations of irinotecan, after UGT1A1 genotyping analysis. The therapeutic results were promising, with the improvement in liver and pulmonary metastases being classified as stable disease and partial response, respectively. Moreover, the progression-free survival was over 6 months. FOLFIRI, with dose escalation of irinotecan according to UGT1A1 genotyping plus regorafenib appears to be a promising salvage therapy for patients with refractory metastatic colorectal cancer.

Online shopping is becoming increasingly popular. However, the perishability of fresh food products requires them to be refrigerated when being shipped, and consumers must also accept the goods immediately when they are delivered. Multiple deliveries are not only a waste of resources but also reduce the freshness of the food products. We examined delivery boxes to design a smart delivery cabinet combined with a cooling chip. Its program uses Message Queuing Telemetry Transport (MQTT) to receive real-time information, view the cabinet's realtime temperature and humidity, set temperature conditions, and open or close the cabinet door. Consumers can remotely open or close the box and adjust its temperature so that they do not have to wait for goods to be delivered at home or waste resources by forcing couriers to make multiple deliveries.

The aim of this study is to design a home monitoring system with a simple and clear visual interface that integrates home appliances, disaster prevention, and surveillance facilities. Furthermore, the Node-RED visual development environment was utilized to create the system, and the users will be able to configure the environmental parameters by themselves with its simple and graphical programming interface, to customize the user interface. In this study, we utilize the Node-RED development software installed on a personal computer and the Message Queuing Telemetry Transport (MQTT) to communicate and exchange data with home devices under the publish/subscribe mode, so that the stability of data transmissions can be ensured while more resources are saved; in addition, MySQL database management tools are used to access the data stored in the home devices for the statistics and analysis of changes in environmental data. Moreover, the HyperText Transfer Protocol (HTTP) is also used to acquire various information from the government's open source data platform, and the information will be integrated and displayed on the Node-RED webpage interface. Since Node-RED uses a webpage interface, the devices that can use web browsers to view webpages, such as computers and smart phones, can thus be used to remotely monitor the Node-RED program. Finally, we utilize the Node-RED development software installed on a personal computer and MQTT to communicate and exchange data with the home devices under the publish/subscribe mode. The smart home system is divided into input and output parts, which control the electrical appliances and read the sensor information. Ten switches on the Web control interface are used to control the living room, kitchen, balcony, and bedroom light switches, air-conditioning, heating, exhaust fans, outdoor lights, doors, and alarm switches.

This article considers the robust passivity analysis for a class of discrete-time recurrent neural networks (DRNNs) with mixed time-delays and uncertain parameters. The mixed time-delays that consist of both the discrete time-varying and distributed time-delays in a given range are presented, and the uncertain parameters are norm-bounded. The activation functions are assumed to be globally Lipschitz continuous. Based on new bounding technique and appropriate type of Lyapunov functional, a sufficient condition is investigated to guarantee the existence of the desired robust passivity condition for the DRNNs, which can be derived in terms of a family of linear matrix inequality (LMI). Some free-weighting matrices are introduced to reduce the conservatism of the criterion by using the bounding technique. A numerical example is given to illustrate the effectiveness and applicability.

Gender differences in terms of mortality among many solid organ malignancies have been proved by epidemiological data. Estrogen has been suspected to cast a protective effect against cancer because of the lower mortality of gastric cancer in females and the benefits of hormone replacement therapy (HRT) in gastric cancer. Hence, it suggests that 17β-estradiol (E2) may affect the behavior of cancer cells. One of the key features of cancer-related mortality is metastasis. Accumulating evidences suggest that human bone marrow mesenchymal stem cells (HBMMSCs) and its secreted CCL-5 have a role in enhancing the metastatic potential of breast cancer cells. However, it is not clear whether E2 would affect HBMMSCs-induced mobility in gastric cancer cells. In this report, we show that CCL-5 secreted by HBMMSCs enhanced mobility in human AGS gastric cancer cells via activation of Src/Cas/Paxillin signaling pathway. Treatment with specific neutralizing antibody of CCL-5 significantly inhibited HBMMSCs-enhanced mobility in human AGS gastric cancer cells. We further observe that 17β-estradiol suppressed HBMMSCs-enhanced mobility by down-regulating CCL5-Src/Cas/paxillin signaling pathway in AGS cells. Collectively, these results suggest that 17β-estradiol treatment significantly inhibits HBMMSCS-induced mobility in human AGS gastric cancer cells.

Development of robust prognostic/predictive biomarkers in patients with colorectal cancer (CRC) is imperative for advancing treatment strategies for this disease. We aimed to determine whether expression status of microRNAs might be a simple and reliable biomarker to detect postoperative early relapse in patients with CRC after radical resection. We used microRNA arrays and identified that microRNA-148a (miRNA-148a) had substantially different expression levels in early and nonearly relapsed stage II and III CRC tissues. The validation study, which included 55 early relapsed patients and 55 nonearly relapsed patients, further confirmed overexpression of miRNA-148a in nonearly relapsed samples. Subsequently, we explored whether the serum level of miRNA-148a can be used to predict early CRC recurrence. The in vitro and in vivo effects of miRNA-148a were examined by cell proliferation, migration, and invasion, as well as cell cycles, and xenograft in null mice. Last, miRNA-148a was investigated as a potential biomarker for identifying early relapse. Cellular studies demonstrated that the overexpression of miRNA-148a inhibited colon cancer cell proliferation and migration but not invasion. The cell cycle studies also revealed that miRNA-148a caused an accumulation of the G2 population. Moreover, lower levels of miRNA-148a expression were associated with significantly shorter disease-free survival rates and poorer overall survival rates. This study showed that miRNA-148a can inhibit tumorigenesis and reduce the early recurrence of CRC. These findings suggest that miRNA-148a may have potential clinical applications for predicting the early relapse of patients with CRC after radical resection.

Objectives We aimed to evaluate the performance of fecal occult blood tests (FOBT) for the screening of colorectal cancer (CRC). Methods We selected participants from a medical center in Taiwan, China from November 2009 to June 2011. All participants underwent screening colonoscopy and were asked to provide their stool samples for qualitative immunochemical FOBT (qlFIT), quantitative immunochemical FOBT (qnFIT) and the guaiac-based FOBT(GT). The receiver operating characteristic curve was utilized to determine the optimal cut-off value of qnFIT. We measured the detection ability of the FOBT for colonic polypoid lesions. Results In all, 699 participants were enrolled in this study. For qnFIT, we found increased levels of fecal hemoglobin in participants with polyps ≥10 mm (251.0 ng/mL), villous-containing adenomas (98.7 ng/mL) and advanced adenomas (187.9 ng/mL). The optimal cut-off value for qnFIT was 25 ng/mL for detecting advanced colorectal neoplasms (ACRN). All three FOBT had a similar but low estimate in detecting small and tubular adenomatous polyps. The qnFIT had a better detection ability for large adenomas (positive likelihood ratio [PLR], 5.6 vs 3.1 vs 0.3) and adenomas with villous-components (PLR 3.7 vs 3.3 vs 0.3) than qlFIT and GT. For the ACRN group, qnFIT also showed the best screening ability with a sensitivity of 56.8%, accuracy of 86.7% and PLR 5.0. Conclusions Both qnFIT and qlFIT perform better than GT in detecting advanced adenomas and CRC in the Taiwanese population.

Different types of proton pump inhibitor (PPI)-based triple therapies could result in different Helicobacter pylori eradication rates. This study aimed to compare the efficacy and safety of rabeprazole- and lansoprazole-based triple therapies in primary treatment of H. pylori infection. From September 2005 to July 2008, 426 H. pylori -infected patients were randomly assigned to receive a 7-day eradication therapy with either rabeprazole 20mgbid (RAC group, n =222) or lansoprazole 30mgbid (LAC group, n =228) in combination with amoxicillin 1gbid and clarithromycin 500mgbid. The patients received follow-up esophagogastroduodenoscopy (EGD) and/or 13 C-urea breath test 12–16 weeks later to define H. pylori status. Their personal and medical history, compliance and side effects were obtained by using a standardized questionnaire. Intention-to-treat analysis revealed that the eradication rate was 87.84% in the RAC group and 85.96% in the LAC group ( p =0.56). All patients returned for assessment of compliance (100% in the LAC group vs. 99.50% in the RAC group; p =0.32) and adverse events (7.20% in the RAC group vs. 5.70% in the LAC group, p =0.51). Univariate analysis suggested that patients with nonsteroid anti-inflammatory agent (NSAID) use had lower eradication rates than those without (76.71% vs. 88.74%; p =0.006). Our results showed that efficacy and safety were similar in rabeprazole- and lansoprazole-based primary therapies. The influence of NSAID usage on H. pylori eradication needs to be further investigated.

Background Composite intravenous fat emulsion, a fat emulsion composed of soybean oil, medium-chain triglycerides (MCT), olive oil, and fish oil, was evaluated for metabolic efficacy, immune modulation, clinical efficacy, safety, and tolerance in surgical gastrointestinal (GI) tumor patients. Methods In a prospective, randomized, double-blind study, 40 patients were randomized after elective digestive surgery to receive isonitrogenous, isoenergetic parenteral nutrition for 5 days postoperatively with either composite 20% IVFE (composed of soybean, MCT, olive, and fish oils) or a conventional long-chain triglyceride (LCT)/MCT 20% IVFE (LCT/MCT IVFE); IVFE was dosed at 1-2 g/kg body weight. Safety and efficacy parameters were assessed on operation day (day 0) and at the end of study (day 6). Adverse events were documented daily and clinical outcomes were recorded and compared between the groups. Results Metabolic parameters, laboratory parameters, proinflammatory cytokine levels, adverse events, and clinical outcomes did not differ between the 2 groups, with the exception that postoperative low-density lipoprotein levels decreased significantly in the composite IVFE group (93.2 ± 24.3 vs 110.5 ± 26.4 mg/dL, P = .038). Conclusions composite IVFE was comparable with conventional LCT/MCT IVFE in efficacy, safety, tolerance, and clinical outcomes in surgical GI tumor patients.

This paper considers the problem of delay-dependent global robust stabilization for discrete, distributed and neutral interval time-varying delayed neural networks described by nonlinear delay differential equations of the neutral type. The parameter uncertainties are norm bounded. The activation functions are assumed to be bounded and globally Lipschitz continuous. Using a Lyapunov functional approach and linear matrix inequality (LMI) techniques, the stability criteria for the uncertain neutral neural networks with interval time-varying delays are established in the form of LMIs, which can be readily verified using the standard numerical software. An important feature of the result reported is that all the stability conditions are dependent on the upper and lower bounds of the delays. Another feature of the results lies in that it involves fewer free weighting matrix strategy, and upper bounds of the inner product between two vectors are not introduced to reduce the conservatism of the criteria. Two illustrative examples are provided to demonstrate the effectiveness and the reduced conservatism of the proposed method.

The objective of this study is to explore the inflammatory modulation effect of glutamine-enriched total parenteral nutrition (TPN) by investigating the alterations of inflammation-related cytokines in gastrointestinal (GI) cancer patients postoperatively. Fifty GI cancer patients received postoperative 7 days of isocaloric and isonitrogenous TPN after operation. They were randomly divided to receive either glutamine-enriched TPN or standard TPN. The inflammation-related cytokines including interleukin-6, interleukin-10, and tumor necrosis factor-α were also determined. Records of nutritional assessments, inflammatory status, and postoperative complications were compared between the two groups. Of 50 enrolled patients, 25 patients were classified as the intervention group, and the control group also comprised 25 patients. The differences of gender, age, primary GI malignancies, and hematological and biochemical data between the two compared groups were not statistically significant (all P > 0.05). Compared with standard TPN, a higher serum prealbumin level and better nitrogen balance were observed in glutamine-enriched TPN ( P = 0.039 and 0.048 respectively). A significantly lower serum interleukin-6 level was found in comparing glutamine-enriched with standard TPN ( P = 0.01), but not in interleukin-10 ( P = 0.374) and tumor necrosis factor-α levels ( P = 0.653). Moreover, a significant lower serum C-reactive protein level was detected in glutamine-enriched TPN compared with standard TPN ( P = 0.013). Indeed, four cases of postoperative infectious complications were noted in the control group, but no postoperative infectious complications were observed in the interventional group ( P = 0.037). Our present study shows that glutamine-enriched TPN may be beneficial in improving the inflammatory status and decreasing the infectious morbidity in postoperative GI cancer patients.
