There were lobectomy in 10, lung wedge resection in 3, excision of intraluminal tumor of bronchus in 3, exploratory thoracotomy in 2 cases. No operation death. Pathological examination revealed 14 cases were typical carcinoid tumor and 4 cases were atypical carcinoid tumor. By 2-13 years follow-up . 3 , 5 and 10 years survival rate were 82% , 78%and 70% respectively. Bronchial carcinoid tumor is often confused with small cell carcinoma of lung, the correct diagnosis can be obtained by light microscopic, electron microscopic and immunohistochemistry studies. Those patients accompanied with ectopic-ACTH secretion always have Cushing,s syndrome , resection of tumor can produce gho result. Proper operation method depends on the location of the tumor and patient's extent of cardiac and pulmonary reserve.Atypical carcinoid tumor had high malignancy and poor prognosis. The size of tumor, lymph node involvement and adjuvant therapy seem no definite effect on the patients' survival rate.展开更多

METHODS： Thirty-two severely malnourished patients with Crohn＇s disease who had undergone surgery in our hospital were reviewed. Sixteen patients who received perioperative parenteral nutrition were enrolled in the study group, and the other 16 patients who did not receive parenteral nutrition were enrolled in the control group. Serum immunoglobulin, body mass index （BMI）, liver function, weight change, and postoperative complications were evaluated. RESULTS： Serum IgM levels elevated 1 wk before surgery in both groups, and decreased to normal value （from 139±41 to 105±29 mg/dL, P = 0.04） 4 wk after operation in the study group, while no significant changes was noted in the control group （from 133±16 to 129±13 mg/dL, P = 0.34）. There were no significant changes in concentrations of IgG and IgA. The BMI of the study group increased from 13.9±0.6 to 15.3±0.7 kg/m^2 （P = 0.02） with no significant change in the control group （14.1±0.7 and 14.5±0.5, respectively, P = 0.81）. The percentage of resuming work was higher in the study group than in the control group. CONCLUSION： Perioperative parenteral nutrition possibly ameliorates the humoral immunity, reverses malnutrition, and facilitates rehabilitation. 2005 The WJG Press and Elsevier Inc.

This article tackles such lacunae by providing a relational perspective based on the extraction of vessel movement archives from the Lloyd's List corpus. Two complementary analyses are proposed: long-term dynamics with all ships included(1890–2008) and medium-term dynamics focusing on container flows(1978–2016). Each analysis examines China's maritime connectivity in various ways and on different spatial scales, from the global to the local, in terms of concentration, vulnerability, and expansion. The main results underline the influence of technological, economic, and political factors on the changing distribution of connectivity internally and externally. In particular, China has managed to reduce its dependence upon external transit hubs, to increase the internal connectivity of its own port system, and to strengthen its dominance towards an increasing number of foreign nodes and trade partners through the maritime network.展开更多

External loads were estimated in the tributaries （Pintados and Ibirit6 creeks） through nutrient concentrations and discharge measurements. Using Fick＇s law, internal loads were estimated in the reservoir from fluxes across sediment-water interface from nutrient concentration gradients between the pore water and the water. The Ibirit6 creek （urban sewage recipient） contributes with 72%-47% of ammonium （NH4^＋） and 100%-8% of SRP （soluble reactive phosphorus） of the total quantity entering the reservoir, whereas the Pintados creek （oil refinery effluent recipient） contributions are 20%-19% and 44%-100%, respectively. Despite the high external loads （130 and 2.2 ton-yr^-1 of NH4＋ and SRP, respectively）, internal loads （average flux of 120 and 2 mg·cm^-2yr^-1, respectively） correspond to 25% of the total external loads which may sustain a high productivity in the reservoir for a long time even if the external loads are controlled. The stocks of ammonium and SRP of the interstitial water （100 cm of sediment） would be released to the water in six years and five months, respectively, The release time would be extremely larger （〉 3,000 years） considering the stocks of total N and bioavailable P.展开更多

Myrtle berries hydrodistilled products and ethanolic extracts are mainly used as flavouring agents and food supplements. This study evaluated the effect of long-term storage on the quality-related properties of myrtle berries. Storage at 2 ~C for three months effbctively preserved myrtle berries quality, both in the chemical composition and external appearance. No symptoms of chilling injury and decay occurred during the first two months of storage, at the end of storage only the 1.3% of rotting was detected. Total anthocyanic content and anthocyanin glycosides diminished whereas the antioxidant capacity increased in all samples till the end of storage. The antioxidant properties of myrtle berries were not correlated with the anthocyanic fraction. The pH of myrtle berries decreased, while gluconic acid levels increased. The results reported in this paper showed that the storage at 2 ~C for three months appears to be an effective way to preserve myrtle berries quality. The changes in the chemical composition of the fruits subjected to storage had revealed the importance of gluconic acid and pH for myrtle quality assessment. These two parameters can be used as quality markers since a strong relationship has been found between myrtle decay and the changes in these parameters,展开更多

It aims at exploring the choice of language and the choice of translation method in the foreign language creation and rootless back-translation of Snow Flower and the Secret Fan, discussing whether these choices adapt to the source language or the target language, and finding out the communicative effects they have achieved. The preliminary results show that： the choice of language and the choice of translation method in Foreign Language Creation mainly adapt to the target language to make easier for the target English readers to understand and partly adapt to the source language to keep local flavor; the choice of language and the choice of translation method in rootless back translation mainly adapt to the target language to make the translation authentic, accurate and smooth, and adaption to source language will lead to translationese. This research sheds new light on this special kind of writing and translation.展开更多
