Objective To improve the diagnostic level of uncommon hepatic malignancy in 5 cases with different histopathological nature by analyzing their CT features. Methods CT scan was performed in 5 cases with pathologically proved uncommon malignancy of the liver including hepatic sarcoma ( n =3) and primary carcinoid tumor ( n =2). Results These uncommon malignancies of the liver had a variety of presentations. Undifferentiated embryonal sarcoma presented as a single huge cyst mixing with solid mass. Hepatic angiosarcoma demonstrated as multiple well defined hypoattenuation lesions without cirrhosis. Necrosis, cystic degeneration, and hemorrhage may be accompanied. Malignant fibrous histiocytoma displayed as a single large hypoattenuation lesion within hyperdense septations, and most of the tumor was in the right lobe. Immunohistochemistry had the diagnostic value. The CT features of carcinoid tumor were single or multiple, unilocular or multilocular mixed dense masses. The solid portion of the masses enhanced obviously and carcinoid syndrome may highly suggest the diagnosis. Conclusion The forementioned 5 cases of hepatic malignancy are seldomly seen clinically. Each of them with different pathologic nature has different CT findings, and sometimes with some similar signs. Typical CT findings, coupled with clinical information may lead to a correct diagnosis.

Ramie and kenaf were traditional fiber crops in China, but their stalk after decorticating has not been used effectively. The stalk contains a lot of cellulose, and can therefore be used for the production of bioethanol. We studied the effects of different chemical pretreatment on enzymatic digestibility of ramie stalk and kenaf stalk. Ramie and kenaf stalks pretreated with alkali were chosen to produce ethanol using quasi-simultaneous saccharification and fermentation (Q-SSF) process. The results show that for the stalks pretreated with 4% NaOH and 0.02% anthraquinone-2-sulfonic acid sodium salt (AQSS) as catalyzer at 170 degrees C for 1 h, the ethanol concentration could reach 51 g/L after fermentation for 168 h at 18% of solid substrate concentration. By fed-batch to 20% of solid substrate concentration, the ethanol concentration could reach 63 g/L, 77% and 79% of the cellulose conversion could get for ramie stalk and kenaf stalk, respectively. For kenaf stalk pretreated with 5.2% NaHSO3 and 0.2% H2SO4 at 170 degrees C for 1 h, the ethanol concentration and cellulose conversion could reach to 65 g/L and 72%, respectively.

It has been 4 years since Natural Health Products Regulations(NHPRs)was enforced by Health Canada in January of 2004.In the past time,how will it affect the marketed Traditional Chinese Medicines(TCM) in Canadian market? Recently,The two TCM products Carditionic Pill (Fufang Danshen Diwan)and Chaihu Pill from Tasly have been newly certificated by Health Canada recently.Taking them as examples,this article introduces the current status.opportunities and challenges for the regulation of TCM in Canada.and suggests that the domestic TCM corporations push the product registration as soon as possible.

Biotechnology supremacy is a newly-advanced power theory. It is a superior dominance of military biotechnological application based on the microcosm of life structure within a certain period of time. The advancement of biotechnology supremacy and modern biotechnology has created the concept of bio-micro-frontier, which involves information and defense resources of all living ultra-micro-organisms with national and regional characteristics. Being feasible both in theory and practice, the implementation of bio-micro-frontier system is strategically important. This article explores the implementation of bio-micro-frontier in terms of strategy and tactics, which will add a unique dimension to future military transformation and active defense.

· AIM: To investigate the complications of intravitreal triamsinolone acetonide (TA) injection in vitrectomy for proliferative diabetic retinopathy (PDR).· METHODS: From February 2005 to January 2007, 18patients (18 eyes) with PDR who were injected with TA in vitrectomy were observed retrospectively after surgery.· RESULTS: During a postoperative follow-up period of 3 to 6 months (mean 4.6 months), some complications including deposit of TA granules on the macular region and surface of the retina (3 eyes), postoperative vitreous hemorrhage (3eyes), elevated intraocular pressure (2 eyes) and pseudohypopyon (1 eye)were observed.· CONCLUSION: The complications after surgery such as deposit of TA granules on the macular region and surface of the retina and pseudohypopyon could be cured without any special treatment. All eyes with elevated intraocular pressure after surgery were controlled by drug. Re-operation may be an effective method for patients with unabsorbable vitreous hemorrhage after vitrectomy.

Objective To explore scanning technique in 64-slice spiral CT angiography, and to evaluate the clinical value of various of post-processing methods.Methods 45 patients were examined with CT angiography, including 4 cases of thoracic aorta, 15 cases of abdominal aorta,10 cases of pulmonary artery, which delay time was determined by bolus tracking. The delay time of others ,including 4 cases of cerebrovascular, 6 cases of cervicum blood vessel and 6 cases of lower limb artery were determined by artifical. The initial images were processed with MPR, CPR, MIP ,SSD and VRT.Results According to standard valuation of imaging quality ,the good images were 37 cases, the better were 8 cases and none was bad.Conclusion As far as the diagnosis of great vessels is concerned, 64-slice spiral CTA can instead of DSA. MIP and VRT are important methods in post-processing of image.

Objective:To explore the application of standardized treatment process for early enteral nutrition combined with gastric retention after operation in patients with esophageal cancer.Methods:Using convenience sampling, 84 patients with gastric retention complicated by early enteral nutrition support after esophagectomy in Department of Thoracic Surgery, Third People′s Hospital of Dalian from July 2015 to June 2020 were selected as the subjects. They were divided into control group and experimental group according to admission time with 42 cases in each group. The control group received routine nursing, while the experimental group received early enteral nutrition and gastric retention standardized treatment process nursing. The differences between the two groups in nutritional status and immune indexes before and 7 days after operation, the standard feeding rate within 7 days after operation, incidence of postoperative complications and enteral nutrition-related complications, length of hospitalization time and hospitalization expenses were compared.Results:In the control group, 2 cases were lost to follow-up. There was no statistically significant difference in preoperative nutritional status and immune indexes between the two groups ( P<0.05); 7 days after operation, the body mass index, serum total protein, prealbumin, nitrogen balance, IgM, CD3, CD4, and CD4/CD8 of the experimental group were all higher than those of the control group, and the differences between the two groups were statistically significant ( t values were 2.228-5.332, P<0.05 or 0.01).The standard feeding rate within 7 days was (68.93±8.12)% in the experimental group and (51.19±6.96)% in the control group, respectively, and the difference between the two groups was statistically significant ( t value was -4.38, P<0.01). The incidence of postoperative nausea and vomiting, Ⅱ B healing, anastomotic fistula and aspiration was 2.38% (1/42), 2.38% (1/42) and 0 (0/42), 2.38% (1/42) in the experimental group and 15.00%(6/40), 7.50% (3/40) and 5.00% (2/40) and 10.00% (4/40) in the control group, respectively, and the differences were statistically significant ( χ2 values were 5.99 - 9.88, P< 0.05 or 0.01). The length of hospitalization time in the experimental group was (10.18±1.69) d, and the hospitalization cost was (53 268.46 ±3 651.56) yuan, both lower than (13.66 ± 2.18) d and (64 972.39 ± 4 029.81) yuan in the control group, and the difference was statistically significant ( t values were 2.14, 2.89, P< 0.05). Conclusions:The standardized treatment process of enteral nutrition combined with gastric retention can improve the feeding rate, nutritional index and immune index within 7 days after operation, reduce postoperative complications and incidence of enteral nutrition related complications, reduce the hospitalization time and reduce hospitalization expenses.
