AIM:To compare ghrelin levels in plasma and gastric mucosa before and after Helicobacter pylori(H.pylori) treatment in children with H.pylori-associated functional dyspepsia.METHODS:Children with H.pylori-associated functional dyspepsia were enrolled in this study.H.pylori infection was confirmed by positive bacterial culture results.All of the children received triple H.pylori eradication therapy(a 2 wk course of omeprazole,amoxicillin,and clarithromycin).The children were divided into two groups based on the success of the H.pylori treatment:group 1(eradicated)-patients who had a negative 13C-urea breath test 2 mo after the end of therapy;and group 2(non-eradicated)-patients who had a positive 13C-urea breath test.Plasma ghrelin,gastric ghrelin mRNA,and the body mass index were evaluated in both groups before and after the H.pylori treatment.The plasma ghrelin levels were measured by a radioimmunoassay.The expression of gastric ghrelin mRNA was determined by real-time reverse transcription polymerase chain reaction.RESULTS:A total of 50 children with H.pylori-associated functional dyspepsia were treated with triple H.pylori eradication therapy.The mean age of the children was 5.52 ± 0.83 years,and there were 28 males and 22 females.Among the 50 H.pylori-positive children,30 successfully achieved eradication,and 20 did not.The mean plasma ghrelin levels of group 1 were 22.17 ± 1.73 ng/L and 26.59 ± 2.05 ng/L before and after the treatment,respectively,which was a significant increase(P = 0.001).However,the mean plasma ghrelin level of group 2 before and after the H.pylori treatment was 21.34 ± 2.40 ng/L and 22.24 ± 2.10 ng/L(P = 0.785).The plasma ghrelin levels increased substantially after treatment in group 1 but showed only minor changes in group 2.Similarly,the gastric ghrelin mRNA expression in group 1 before treatment was 2.84 ± 0.08.After treatment,the level was 3.11 ± 0.65,which was significantly different(P = 0.023).The gastric ghrelin mRNA expression in group 2 did not change significantly during the treatment(2.82 ± 0.44 vs 2.79 ± 0.31,P = 0.875).The plasma ghrelin and gastric ghrelin mRNA levels in group 1 increased substantially after the treatment but did not do so in group 2.In addition,the body mass index the two groups did not differ significantly 2 mo before and after the H.pylori treatment.CONCLUSION:H.pylori eradication increases the plasma and tissue ghrelin levels in children with H.pylori-associated functional dyspepsia. 展开更多

Change related to climate in Macao was studied on the basis of daily temperature observations over the period 1901-2007. The result shows that annual mean surface air temperature in Macao as a whole rose with a warming rate of about 0.066℃ per 10 years in the recent 107 years. The most evident warming occurred in spring and winter. The interdecadal variations of the seasonal mean temperature in summer and winter appeared as a series of waves with a time scale of about 30 years and 60 years, respectively. The annual mean minimum temperature increased about twice as fast as the annual mean maximum temperature, resulting in a broad decline in the annual mean diurnal range. The interdecadal variations of annual mean maximum temperature are obviously different from those of annual mean minimum temperature. It appears that the increase in the annual mean maximum temperature in the recent 20 years may be part of slow climate fluctuations with a periodicity of about 60 years, whereas that in the annual mean minimum temperature appears to be the continuation of a long-term warming trend. 展开更多

AIM: To investigate the efficacy of topical application of 0.5% nifedipine ointment in healing acute anal tissue and preventing its progress to chronicity. METHODS: Thirty-one patients (10 males, 21 females) with acute anal fissure from September 1999 to January 2005 were treated topically with 0.5% nifedipine ointment (t.i.d.) for 8 wk. The patients were encouraged to follow a high-fiber diet and assessed at 2, 4 and 8 wk post-treatment. The healing of fissure and any side effects were recorded. The patients were subsequently followed up in the outpatient clinic for one year and contacted by phone every three months thereafter, while they were encouraged to come back if symptoms recurred. RESULTS: Twenty-seven of the 31 patients completed the 8-wk treatment course, of them 23 (85.2%) achieved a complete remission indicated by resolution of symptoms and healing of fissure. Of the remaining four unhealed patients (14.8%), 2 opted to undergo lateral sphincterotomy and the other 2 to continue therapy for four additional weeks, resulting in healing of fissure. All the 25 patients with complete remission had a mean follow-up of 22.9 ± 14 (range 6-52) too. Recurrence of symptoms occurred in four of these 25 patients (16%) who were successfully treated with an additional 4-wk course of 0.5% nifedipine ointment. Two of the 27 (7.4%) patients who completed the 8-wk treatment presented with moderate headache as a side effect of nifedipine. CONCLUSION: Topical 0.5% nifedipine ointment, used as an agent in chemical sphincterotomy, appears to offer a significant healing rate for acute anal fissure and might prevent its evolution to chronicity. 展开更多

Objectives:Helicobacter pylori(H.pylori)infection is one of the most common infections,for which wellestablished medical treatments have been widely used,such as quadruple therapy and sequential therapy.However,some patients still suffer from the infection after multiple treatment.Traditional Chinese medicine(TCM)has been widely used to treat the H.pylori infection.Whether the combination of TCM therapy and antibiotic treatment is effective for these patients with repeated infection with H.pylori needs clinical observation.Methods:In this study,we reported two cases with refractory H.pylori infection.One is a 60-yearold Chinese woman with diagnoses of chronic atrophic gastritis and H.pylori infection,who has an uncomfortable feeling in her stomach with a poor appetite,depression and irregular defecations.The other is a Vietnamese woman aged 46,who had abdominal pain for 11 years.We treated the two patients with Chai Ping Decoction,combined with sequential therapy.Results:Both patients had pain relieved and H.pylori infection eradicated after treatment.Conclusion:TCM therapy may eliminate H.pylori infection well with sequential therapy.Based on the TCM theory,the patients who were diagnosed as spleen deficiency and dampness with abdominal uncomfortable symptoms could be well treated. 展开更多

Tsunamis in Mexico are a real threat, still unknown to many, mainly by people living in or visiting the coast. The Tsunami Warning Center in Mexico recently created (September 19, 2011) monitors earthquakes and sea level change caused by these same. Sea level on the west coast of the Mexican Pacific was analyzed after the occurrence of local, regional and distant earthquakes, in order to determine the existence of an anomaly due to the quake itself. Variations in sea level due to local registered earthquakes Mw 6.0 to 7.4 range was from 0.10 to 0.30 m; for regional earthquakes of Mw 7.3 and 8.2 were 0.12 and 0.22 m respectively and to the distant earthquake of Mw 8.0 recorded in Solomon Islands, the change in sea level of the maximum recorded was 0.20 m in Manzanillo, Colima. It is important to know that earthquakes whether local, regional or distant whose magnitudes are in the range specified here, did not present a risk to the Mexican coast, but do not rely, having to monitor variations in sea level that earthquakes can produce and be aware that you may perhaps occur as a tsunami in Indonesia in 2004 or Japan in 2011. 展开更多

The second-tier extended metropolises in the Changjiang (Yangtze) River Delta, including Suzhou, Wuxi and Changzhou near Shanghai, are becoming the most active and new innovative industrial agglomerating areas. Manufacturing industries in these second-tier cities have been in rapid growth due to increasing foreign investment. Nevertheless, the economic prospect of these cities is still constrained by a lack of local R&D capacity and production services, which are mainly dependent upon Shanghai. This paper analyses the impact of globalization on the new economic sectors in these cities, the change of industrial structure, the limitation of urban development and the problem of sustainability. Then, the paper analyses the conditions for the high-tech industry and production services in these areas. Also, it applies the industrial organization theory to these cities and examines how these cities can cooperate with each other in terms of horizontal linkages. Finally, the paper gives the future growth prospects in high-tech industry and production services. 展开更多

Long-term climatic data (maximum temperature, minimum temperature, rainfall and evaporation) for Big Bend in the Lowveld, a semi-arid region of Swaziland, were analysed for any changes or variations. Evaporation and rainfall data were analysed to assess water resources availability in the region. Analysis of the available data shows that there is no indication of decrease in rainfall with time, but the results show that there has been a steady increase in minimum temperatures over the last 25 years. The average effective water resources index, measured as the difference between mean annual rainfall and mean annual evaporation, for the region in the period from 1965 to 2001 was -1,500 mm. The large negative index implies low available water for the region, a situation that is likely to affect agricultural, hydropower and other water related development activities in the region. The negative effective water index implies deficits in the region's water resources which call for better management of the region's water resources. In the agriculture sector, this requires promoting technologies and practices that provide for water saving, improved water use performance and high water productivity. These include soil conservation tillage, wastewater reuse, runoff harvesting and soil fertility interventions through application of fertilizers, manures and mulches, and agronomic management. There is need for more analysis for the other regions in order to get a countrywide picture of the climate as well as water resources situations. 展开更多
