Clinical treatments for gastric ulcer have allowed the rapid development of potent anti-ulcer drugs during the last several decades. Gastric ulcer healing is successful with conventional treatments including H2-receptor antagonists, and proton pump inhibitors(PPIs) have been essential for ulcer healing and prevention of complications. Additionally, Helicobacter pylori eradication therapy is effective in reducing ulcer recurrence and leads to physiological changes in the gastric mucosa which affect the ulcer healing process. However, in spite of these advancements, some patients have suf-fered from recurrence or intractability in spite of continuous anti-ulcer therapy. A new concept of the quality of ulcer healing(QOUH) was initiated that considers the reconstruction of the mucosal structure and its function for preventing ulcer recurrence. Although several gastroprotection provided these achievements of the QOUH, which PPI or other acid suppressants did not accomplish, we found that gastroprotection that originated from natural products, such as a newer formulation from either Artemisia or S-allyl cysteine from garlic, were very effective in the QOUH, as well as improving clinical symptoms with fewer side effects. In this review, we will introduce the importance of the QOUH in ulcer healing and the achievements from natural products.展开更多

Although earlier management for SAP should aim to either treat organ failure or reduce infectious complications, the current standard of care for the general management of AP in the first hours to days after onset of symptoms include intravenous fluid replacement, nutritional changes, and the use of analgesics with a close monitoring of vital signs. Furthermore, repeated evaluation of severity is very important, as the condition is particularly unstable in the early stages. In cases where biliary pancreatitis is accompanied by acute cholangitis or in cases where biliary stasis is suspected,an early endoscopic retrograde cholangiopancreatography is recommended.However,practice guidelines regarding the treatment of pancreatitis are suboptimal.In chronic pancreatitis,conservative management strategies include lifestyle modifications and dietary changes followed by analgesics and pancreatic enzyme supplementation.Recently,attention has been focused on phytoceuticals or antioxidants as agents that could surpass the limitations associated with currently available therapies.Because oxidative stress has been shown to play an important role in the pathogenesis of pancreatitis,antioxidants alone or combined with conventional therapy may improve oxidativestress-induced organ damage.Interest in phytoceuticals stems from their potential use as simple,accurate tools for pancreatitis prognostication that could replace older and more tedious methods.Therefore,the use of antioxidative nutrition or phytoceuticals may represent a new direction for clinical research in pancreatitis.In this review article,recent advances in the understanding of the pathogenesis of pancreatitis are discussed and the paradigm shift underway to develop phytoceuticals and antioxidants to treat it is introduced.Despite the promise of studies evaluating the effects of antioxidants/phytoceuticals in pancreatitis,translation to the clinic has thus far been disappointing.However,it is expected that continued research will provide solid evidence to justify the use of antioxidative phytoceuticals in the treatment of pancreatitis.展开更多

Methods A total of 7200 subjects （3600 cases and 3600 controls） were randomly sampled from a cross-sectional study, and they were investigated for individual and occupational factors of low back pain. The potential risk factors were first selected by using chi-square tests. Secondly, collinearity diagnosis proceeded by using the Kendall＇s rank correlation. Finally, binary logistic regression model was used for multi-factor analysis. Results Collinearity diagnosis showed that there was a severe collinearity problem among the potential risk factors of low back pain. Logistic regression model included 20 variables with statistical significance. Bending neck forward or holding neck in a forward posturefor long periods （0R=1.408） was the most important risk factor inducing low back pain in this study, followed by bending heavily with the trunk （0R=1.402）, carrying out identical work almost for the whole day （0R=1.340）. Additionally, suHicient normal break was a protective factor of low back pain. Conclusion Low back pain among the Chinese occupational population was associated with body height, occupation, work organization, physical work, working posture, and others. All these risk factors could be regarded as the indicators of low back pain, and some relevant preventive measures should be taken to reduce low back pain risk.展开更多

Information on sleep quality was collected using Pittsburg Sleep Quality Index(PSQI). A questionnaire was used to collect data on sociodemographic lifestyle factors and psychological distress. This questionnaire was completed through an interview, and clinical information was extracted from patient's record. Data analysis was done using SPSS software version 23 and univariate andmultivariate analyses.RESULTS Study participants consist of 256 people with T2 DM the majority of whom were women(70%), and mean age of participants was 54.06 ± 9.09. The mean of total score of PSQI was 5.56 ± 3.34. Relative to younger age group, the middle-aged people with T2 DM were twice more likely to be poor sleeper; the adjusted OR was 2.03(95%CI: 1.01-4.08); and those with longer duration of diabetes were about 1.8 times more likely to report poor quality of sleep(ORadj = 1.77, 95%CI: 0.98-3.13). Participants with cholesterol level ≥ 240 mg/dL were about twice more likely to be poor sleeper(ORadj = 1.99, 95%CI: 1.01-3.94). The odds of being poor sleeper increased as the level of distress increased(1.84-4.09).CONCLUSION As indicated by the results of the present study, some factors including age, duration of disease, psychological distress and high level of cholesterol were independently associated with poor sleep quality.展开更多

Brain injuries vary by name, type, and severity in the athletic setting. It should be noted, however, that these injuries are not isolated to only the athletic arena, as non-athletic mechanisms （e.g., motor vehicle accidents） are more common causes of traumatic brain injuries （TBI） among teenagers. Notwithstanding, as many as 1.6 to 3.8 million TBI result from sports and recreation each year in the United States alone. These injuries are extremely costly to the global health care system, and make TBI among the most expensive conditions to treat in children. This article serves to define common brain injuries in sport; describe their prevalence, what happens to the brain following injury, how to recognize and manage these injuries, and what you can expect as the athlete recovers. Some return-to-activity considerations for the brain-injured athlete will also be discussed.展开更多

It indicates that doctors in general hospitals have worse mental status. Occupational stress comes from over workload, high demanding from patients, occupational risk, effort-reward imbalance and fierce competition for job promotion. For medical staffs battling against severe acute respiratory syndrome (SARS), or working in catastrophic Wenchuan earthquake-affected areas, they have elevated stress and worrying levels of psychological distress. Post-traumatic stress disorder (PTSD) is a common mental health problem among them. The most common diseases the Chinese doctors usually suffered were cervical spondylosis, hyperlipidemia, hypertension, fatty liver and hyperglycemia. It could be important for health administrators to note that mental health appears to be an?increasing problem in Chinese doctors and corresponding helping measure should be made.展开更多

Sleep patterns and sleep problems in children are not only influenced by a large number of biological and psychologic factors but also by cultural and social factors. Little is known about similarities and differences in sleep patterns and sleep problems among children across countries. We attempted to compare sleep patterns and sleep problems among schoolchildren from 2 countries with distinctive cultural contexts: the United States and China. Methods. The data come from 2 cross-sectional surveys in 3 elementary schools of Jinan City, People’s Republic of China, and 3 elementary schools from a suburban school district in southeastern New England, United States. The Chinese sample consisted of 517 elementary school children (grades 1 to 5), and the US sample consisted of 494 elementary school children (grades kindergarten through 4). We used the Children’s Sleep Habits Questionnaire (CSHQ) to assess children’s sleep patterns and sleep problems as reported by parents. Parents of the Chinese sample completed a Chinese version of the CSHQ. Results. For children in both the US and Chinese samples, reported bedtime was delayed and sleep duration decreased with increasing age. Compared with the US children (grades 1-4), Chinese children went to bed approximately half an hour later (9:02 vs 8:27 PM) and woke up half an hour earlier (6:28 vs 6:55 AM), resulting in an average sleep duration that was 1 hour less (9.25 vs 10.15 hours). Chinese children were rated significantly higher than the US children on almost all CSHQ scales, indicating more sleep problems in Chinese children. Common sleep problems observed for all children were difficulty falling asleep, having a fear of sleeping in the dark, sleep talking, restless sleep, teeth grinding during sleep, and daytime sleepiness. Shorter daily sleep duration was associated with difficulty falling asleep, struggling at bedtime, and trouble sleeping away for the US children, and with going to bed at different times and having a fear of sleeping alone for Chinese children. Short sleep duration was a main predictor of daytime sleepiness for Chinese children, whereas restless sleep and snoring predicted daytime sleepiness for the US children. Conclusions. As reported by parents, children in China went to bed later and woke up earlier and their sleep duration was 1 hour shorter than the US children. Chinese children were reported to have more sleep problems than their US counterparts. Daytime sleepiness was determined by sleep duration only for those who slept insufficiently. Unique school schedules and sleep practices may contribute to the differences in the sleep patterns and sleep problems of children from the United States and China.展开更多

In addition to exploring the interactions between hosts and microbes, referred to as the microbiome, a variety of strategies that can be tailored to an individual in the coming era of personalized medicine in the treatment of IBD are being investigated. These include prompt genomic screening of patients at risk of developing IBD, the utility of molecular discrimination of IBD subtypes among patients diagnosed with IBD, and the discovery of proteome biomarkers to diagnose or predict cancer risks. Host genetic factors influence the etiology of IBD, as do microbial ecosystems in the human bowel, which are not uniform, but instead represent many different microhabitats that can be influenced by diet and might affect processes essential to bowel metabolism. Further advances in basic research regarding intestinal inflammation may reveal new insights into the role of inflammatory mediators, referred to as the inflammasome, and the macromolecular complex of metabolites formed by intestinal bacteria. Collectively, knowledge of the inflammasome and metagenomics will lead to the development of biomarkers for IBD that target specific pathogenic mechanisms involved in the spontaneous progress of IBD. In this review article, our recent results regarding the discovery of potential proteomic biomarkers using a label-free quantification technique are introduced and on-going projects contributing to either the discrimination of IBD subtypes or to the prediction of cancer risks are accompanied by updated information from IBD biomarker research.展开更多
