Objective To improve the recognition of meconium ileus and pseudohypoaldosteronism type Ⅰ and to explore the relationship between neonatal meconium ileus and cystic fibrosis.Methods The clinical and follow-up data of a premature infant with meconium ileus and pseudohypoaldosteronism type Ⅰ was analyzed.Relevant literature was reviewed.Results The child was a very low-birth weight premature infant who didn′t pass meconuim within 24 hours of birth and persistent abdominal distention was noted.Laparotomy was performed on day 4.Thick and inspissated meconium was found in the ileum with perforation.The atretic intestine was resected,and a double-barreled enterostomies was performed.On day 30,the child presented hyponatremia,hyperkalemia,high levels of plasma renin and aldosterone and was given 9 g/L salt supplementation.At 6-month age,9 g/L salt supplementation was discontinued.Anastomosis was performed at 8-month age.The child recovered with a good prognosis whose catch-up growth was obtained at 18-month age and didn′t pre-sent manifestations of cystic fibrosis.Conclusions This case could be diagnosed as meconium ileus and pseudohypoaldosteronism type Ⅰ.The relationship between neonatal meconium ileus and cystic fibrosis is different in China and the regions of Caucasian.

· Vascular endothelial growth factor is indispensable inducing factor in retinalangiogenesis. After the retinal neovascularization of proliferative diabetic retinopathy ( PDR ) patients, it can cause fibrovascular membrane formation, epiretinal membrane fibrosis increased, resulting in traction retinal detachment with further aggravate the condition. The recent research suggests that cytokines promote fibroblast proliferation, movement, adhesion, and secretion of extracellular matrix functions in the diabetic state of the environment changes to profibrogenic state, resulting in the accumulation and fibrosis of extracellular matrix. This paper reviewed the status quo of the correlation between vascular endothelial growth factor and fibrosis-related cytokine.

Permeabilized cells containing trehalose synthase from Meiothermus sp.CBS-01 was immobilized by the integration of entrapment in alginate beads with cross-linking and electrostatic self-assembly coating technique.Coating on alginate beads with diazo-resin and poly(styrene sulfonate) can protect the beads from degradation in phosphate buffer,whereas cross-linking with carbodiimide improves the thermostability of trehalose synthase entrapped in alginate beads.By co-immobilization of permeabilized cells using entrapment-cross-linking- coating method,the enzyme recovery was 32%,and the optimum temperature of the enzyme was still 60℃,but the optimum pH was shifted from 6.5 to 7.In batch manner,a maximum conversion yield of 60% trehalose from maltose could be reached by the immobilized cells.Within 4 times repeated use of the immobilized cells,and each time was operated at 50℃ for 24h,more than 50% conversion yield of trehalose could be maintained with less than 20% loss of the enzyme activity.

Objective To address the neural basis of Chinese idioms processing with different kinds of stimuli using an event-related fMRI design.Methods Sixteen native Chinese speakers were asked to perform a semantic decision task during fMRI scanning.Three kinds of stimuli were used: Real idioms (Real-idiom condition);Literally plausible phrases (Pseudo-idiom condition,the last character of a real idiom was replaced by a character with similar meaning);Literally implausible strings (Non-idiom condition,the last character of a real idiom was replaced by a character with unrelated meaning).Reaction time and correct rate were recorded at the same time.Results The error rate was 2.6%,5.2% and 0.9% (F = 3.51,P0.05 )for real idioms,pseudo-idioms and wrong idioms, respectively.Similar neural network was activated in all of the three conditions.However,the right hippocampus was only activated in the real idiom condition,and significant activations were found in anterior portion of left inferior frontal gyrus (BA47)in real-and pseudo-idiom conditions,but not in non-idiom condition.Conclusion The right hippocampus plays a specific role in the particular wording of the Chinese idioms.And the left anterior inferior frontal gyms (BA47)may be engaged in the semantic processing of Chinese idioms.The results support the notion that there were specific neural bases for Chinese idioms processing.

Objective To evaluate the value of the Bedside Index for Severity in Acute Pancreatitis (BISAP) in diagnosing severe acute pancreatitis. Methods Sixty-eight patients with suspected diagnosis of severe acute pancreatitis were collected and were scored by BISAP, APACHE Ⅱ , Ranson and CTSI scoring systems, respectively. BISAP scoring system included the blood urea nitrogen, impaired mental status,systemic inflammatory response syndrome, age, and pleural effusion. The diagnosis criteria of severe acute pancreatitis was BISAP ≥ 3 points or APACHE IⅡ ≥ 8 points, Ranson ≥ 3 points, CTSI ≥ 3 points. The diagnostic accuracy of SAP of these scoring systems was calculated. Results Among these 68 cases, 63.2%(43/68) were graded ≥ 3 points in BISAP scoring system;60.3% (41/68) were marked ≥8 points in APACHE Ⅱ scoring system; 60.3% (41/68) were scored ≥ 3 points in Ranson scoring system; and 67.6%(46/68) were scored ≥3 points in CTSI scoring system. There was no statistical difference between BISAP scoring system and other three scoring systems in diagnosing severe acute pancreatitis. Conclusions As a new and simple scoring system, BISAP scoring system can be widely used in the diagnosis of severe acute pancreatitis.
