Ef-cd gene is a dominant earliness gene located on the short arm of rice chromosome 3. In this paper, through continuous backcross, self-pollination and molecular marker assisted selection, individual Ef-cd gene was isolated and its nearly isogenic lines were constructed by using early-maturing indica line 6442S-7 as the donor parent, and by using latematuring indica line Minghui 63 （MH63）, Shuhui 881 （SH881） and Shuhui 527 （SH527） as the recurrent parents （genetic background）, respectively. Further, it was found out that Ef-cd gene could generally advance rice to head 11-14 d earlier. So, it was considered that Ef-cd gene played an important role in rapid developing early-maturing and super high-yielding rice varieties.

Background Laparoscopic Heller cardiomyotomy and Dor fundoplication is the surgical procedure of choice for esophageal achalasia. The aim of this study was to investigate the clinical outcome of laparoscopic Heller-Dor procedure in our initial series of 25 patients with achalasia. Methods Between October 2003 and January 2006, a total of 25 patients with achalasia underwent laparoscopic Heller-Dor operation. Among them, 9 were male and 16 were female with an average age of （41.5 ± 5.1） years （21- 66）. All the patients received upper gastrointestinal series （barium swallow）, esophagogastroscopy, esophageal manometry to exclude esophageal carcinoma and to confirm the diagnosis, and 21 patients also had 24-hour ambulatory pH studies. All the patients were operated by laparoscopic modified Heller＇s myotomy with Dor fundoplication. In addition, 2 of them had combined laparoscopic cholecystectomy ± excision of hepatic hemangioma and laparoscopic cholecystectomy, respectively. Results The average operating time was （110.6± 12.9） minutes （range, 60-180）, operative blood loss averaged （18.6±7.1） ml （5-50）, the median time to oral feeding was （1.6±0.4） days （1-4） and the median hospital stay was （12.6± 1.2） days （10-20）. There was no conversion to open surgery. Intraoperative mucosal perforation was encountered in six patients and was repaired in all of them by laparoscopic suture. All the patients had an uneventful recovery without postoperative complication. After a median follow-up of （10.6 ± 7.2） months （1 -27）, 24 patients were asymptomatic and 1 had mild postoperative dysphagia. Conclusions Laparoscopic Heller-Dor operation had the advantages of reduced compromise of the cardiopulmonary function, with less disruption of the supporting structures （phrenoesophageal membrane） of the antireflux mechanism, requiting simpler general anesthesia and providing excellent exposure permitting an easy fundoplication, less pain and reduced morbidity, shorter hospitalization and

Background Gastroesophageal junction adenocarcinomas include adenocarcinomas of the distal esophagus （DE） and gastric cardia （GC）. It is controversial whether these tumors are the same entity and whether they have the same survival rates. Patients with DE and GC adenocarcinomas have a similar survival rate in the US; however, data are lacking in Asian countries. Therefore, we conducted a retrospective study to understand the implications of the tumor location in the survival of Asian patients. Methods A total of 209 patients with pathologically confirmed DE and GC adenocarcinomas, from 2005 to 2007, were included in the study. We identified patients with adenocarcinomas of the DE （DE group, n=91） and GC （GC group）（n=118）, We performed an unadjusted survival analysis using the Kaplan-Meier method, and used a Cox proportional hazards regression model to adjust for potential confounding covariates. Results We found no significant difference between the overall survival of the DE and GC groups. The 3-year survival rates were 44.8% and 53.0%, respectively, and the 5-year survival rates were 27.9% and 30.2%, respectively （P=0.162）. We found no significant difference in early staging, advanced staging, different T staging, and different N staging, between the groups. Both advanced post-operative N staging and advanced AJCC staging had a significant adverse effect on survival. Conclusions Patients with DE and GC adenocarcinomas have similar survival rates in the Asian population. Both post-operative N staging and AJCC staging are prognostic factors.

AIM: To investigate the gastrointestinal bleeding (GIB) in people from lowland to high altitude and in workers on Mountain Tanggula and its causes as well as treatment and ***: From 2001 to October 2003, we studied GIB in 13 502 workers constructing the railroad on Mountain Tanggula which is 4905 m above the sea level. The incidence of GIB in workers at different altitudes was recorded. Endoscopy was performed when the workers evacuated to Golmud (2808 m) and Xining (2261 m). The available data on altitude GIB were ***: The overall incidence of GIB was 0.49% in 13 502 workers. The incidence increased with increasing altitude. The onset of symptoms in most patients was within three weeks after arrival at high altitude. Bleeding manifested as hematemesis, melaena or hematochezia, and might be occult. Endoscopic examination showed that the causes of altitude GIB included hemorrhage gastritis, gastric ulcer, duodenal ulcer, and gastric erosion. Experimental studies suggested that acute gastric mucosal lesion (AGML) could be induced by hypoxic and cold stress, which might be the pathogenesis of altitude GIB. Those who consumed large amount of alcohol, aspirin or dexamethasone were at a higher risk of developing GIB. Persons who previously suffered from peptic ulcer or high-altitude polycythemia were also at risk of developing GIB. Early diagnosis, evacuation, and treatment led to early recovery. CONCLUSION: GIB is a potentially life threatening disease, if it is not treated promptly and effectively. Early diagnosis, treatment and evacuation lead to an early recovery. Death due to altitude GIB can be avoided if early symptoms and signs are recognized.

1920年代苏联文坛出现的现实艺术协会的“现实”不同于现实主义的“现实”,现实艺术协会追求的并非客观再现基础上的“现实的艺术”,而是坚持艺术的独立性,将艺术看作与生活一样的现实存在。作为协会的成员,扎博洛茨基在其早期创作中秉承“艺术的现实”,通过展现非决定论视阈下的真实、降低语言的忠实度、利用儿童对世界的“不理解”及其与成人的错位,将文学从依赖于再现现实转换为表现现实,将文学现实的范畴从外部世界扩展到内部世界。扎博洛茨基的早期先锋创作揭示了客观现实的历史性与主观精神现实的永恒性。
