Objectives:To study the clinical significance of prealbumin and retinol binding protein in parenteral nutrition assessment. Methods:Serum prealbumin,retinol binding protein,transferrin and albumin were determined respectively before and a week after total parenteral nutrition(TPN) support in 40 cases with gastrointestinal diseases. Results:A week after TPN,plasma prealbumin and retinol binding protein concentrations increased significantly( P

Objective: To overview the experience of postoperative nutritional management in live transplant patients. Methods: Postoperative nutritional therapy and nutritional status assessment in 18 liver transplantation (2 patients undergone retransplantation) were retrospectively analyzed. During the first 3 days after operation, patients were supported with total parenteral nutrition (TPN) and supplied with human albumin. On the 4th and 5th days after operation, patients were provided with parenteral nutrition (PN) and enteral nutrition (EN). And on days 6～10 after operation, patients were gradually transferred to total enteral nutrition and they restored the oral intake completely on days 12～18 after operation. Recombinant human growth hormone was postoperatively injected for 4～7 days. Results: Despite 3 cases who died from brain hemorrhage, respiratory failure and acute rejection respectively, other 13 cases recovered fluently. Conclusions: Appropriate postoperative nutritional therapy facilitated the recovery of liver transplant patient.

Objective To further elucidate the CT characteristics and diagnostic approaches to non-acquired immune deficiency syndrome patients with pulmonary cryptococcosis. Methods The histories of forty-two pulmonary cryptococcosis (PC) patients diagnosed in Zhongshan Hospital from 2003 -2008 were collected and analyzed for demography data, underlying conditions, clinical symptoms, chest CT and diagnostic studies. Results None of the 42 PC patients had avian or its feces contacting history, and 71.4% (30/42) of them were immunocompetent. The most frequent CT lesions were multiple nodules (67. 9% ) with peripheral predominance (67. 9% ), and cavitations (50%) often presented within them. Masses/consolidation (31.4%) and patching lesions (2. 9% ) could exist occassionally. Positive detection rates of non-aggressive examinations including sputum, bronchoalveolar lavage fluid and bronchofibroscope aspiration were 4. 3%, 8. 3% and 6. 3% respectively, while those of aggressive approaches including transbrunchial lung biopsy (TBLB), thin needle aspiration biopsy (TNAB) and pneumonectomy by surgery were 64. 7%, 64. 3% and 100% respectively. Non-aggressive serum cryptococcus antigen test was performed in 14 patients who had been diagnosed by histopathology or pathogen culture, and all of them were positive. Conclusion Our study suggests that PC is common in immunocompetent population. Avian or its feces contacting is not so important as used opinion to PC differential diagnosis. CT characteristics of PC are diversiform and always change very slowly. Besides the most frequent multiple nodules with subpleural predominance, pulmonary lesions can present as masses, consolidation or patchings. Aggressive techniques such as TBLB and TNAB are benefit to clinical diagnosis of PC, and non-aggressive serum cryptococcus antigen test may be promising for its early diagnosis as well as clinical course follow-up and therapeutic effect evaluation.
