Objective To study the subclavian artery angiography for hemoptysis and its clinical value.Methods Thirty-eight cases of hemoptysis undertook subclavian artery angiography after embolization of bronchial arteries and branches of thoracic aorta. Group A: 4 recurrent cases underwent subclavian artery angiography (unilateral: n =2, bilateral: n =2). Group B: 16 cases underwent subclavian artery angiography according to the manifestation on X-ray and CT (right: n =10, left: n =6). Group C: 18 cases underwent bilateral subclavian artery angiography.Results of subclavian artery angiography were divided into three classes: normal(-),chaotic and hyperplasia of small branchi vessels(+),obviously bleeding (++).Some of the obviously bleeding cases were embolized and analysed for clinical efficacy and complications. Results Bleeding cases accounted for 63.2%(24/38)and bleeding subclavian arteries accounted for 50%(29/58), including(++):37.9%(22/58) and(+): 12.1%(7/58). Positive rate of chronic fibro-cavitary pulmonary tuberculosis was the highest. Bleeding sites were coincided with lung lesions. Twelve cases were embolized with the immediate cessation rate of hemoptysis reaching 100%. Eight cases with long-term follow-up showed 5 cured, 1 with significant effect and 2 recurrent. The complications occurred with fever, vomiting, chest pain, hiccup and dyspnoea.Conclusions Subclavian artery angiography has important clinical value in artery embolization for hemoptysis, especially for lesions in the upper lobes of lungs and with more fruitful result for chronic fibro-cavitary pulmonary tuberculosis.

Objective To analyze the incidence, clinical feature and late complications, and treatment for diabetes ketoacidosis (DKA) in children with type 1 diabetes mellitus.Methods Ninty children with type 1 diabetes mellitus within 10 years were retrospectively reviewed.The onset situation,clinical feature and long-term complication,and treatment of DKA were analized.Results High morbidity was found in 10 to 16 years old children.DKA was often caused by infection; late complications of diabetes mellitus was resulted from interrupted injection of insulin.Conclusions Emergency treatment for DKA may involve the injection of small dose insulin,correction of the disorder of water and electrolysis and regulation of acid-base.The education of patients and parents about diabetes mellitus and long-term injection of insulin are of importance in preventing the complications.

Objective To investigate the angiographic manifestation of the proper esophageal artery (PEA),the hish risk factom for the presence of the anomalous PEA in hemoptysis and to evaluate the safety of transcatheter aaefial embolization(TAE) of the PEA using gelatin sponge(GS).Methods Selective esophageal arteriography WSS performed in forty-three patients with hemoptysis,including 15 cases of pulmonary tuberculosis,18 cases of bmnchiectasis,7 cases of posttuberculous bronchiectasis and three cases of lung cancer. One case experienced failure of bronchial arterial embolization. The angiographic manifestation of the PEAs Was studied.The complications of the procedure and clinical results were observed in the patients who underwent TAE using GS.Results Thirty-nine PEAs were catheterized selectively in 37 patients(86.0%).Eighteen anomalous PEAs(46.2%)were catheterized selectively in 17 patients (45.9%).The anomalous PEAs showed tortuosity,dilatation,hyperplasia,shunting with pulmonary artery and anastomosis with the bronchial artery.All lesions involved basal segment of inferior pulmonary lobar. Bronchiectasis Was the most frequent disease for PEA abnormality. No complications occurred and satisfactory curative effect Was achieved with TAE of the anomalous PEAs.Conclusions It is necessary to perform selective proper esophageal arteriography when the lesion involves basal segment of inferior pulmonary lobar in hemoptysis.Supplemental TAE of the anomalous PEA using GS is safe and valuable in the management of hemoptysis.

BACKGROUND: Severe acute pancreatitis (SAP) can result in intestinal mucosal barrier (IMB) dysfunction. This study was undertaken to demonstrate the effect of IGF-I on the intestinal mucosal barrier in rats with SAP and its possible mechanisms. METHODS: Seventy-two male Wistar rats were randomly divided into three groups: a sham operation (SO group,n=24), a SAP group not treated with IGF-I (SAP group,n=24), and a SAP group treated with IGF-I (IGF-I group,n=24). SAP was induced in the rats by injecting 5.0％ sodium taurocholate into the biliary-pancreatic duct. The SO rats were given an infusion of normal saline instead. The rats in the IGF-I group underwent the SAP procedure and were given a subcutaneous injection of IGF-I at 30 minutes before the operation and at 3 hours after the operation. Eight rats in each group were sacrificed at 6, 12 and 24 hours after operation. Apoptosis of mucosal cells in the small intestine was determined by TUNEL. The levels of endotoxin and DAO and serum amylase were also measured. Pathologic changes in the small intestine were monitored. Changes of bax and bcl-2 mRNA expression in the small intestine were determined by reverse transcription polymerase chain reaction (RT-PCR). RESULTS: The levels of serum amylase were lower in the IGF-I group than in the SAP group at all three time points (P<0.05). The levels of endotoxin in the IGF-I group were higher than those in the SAP group at 6 hours, but lower in the IGF-I group than in the SAP group at 12 and 24 hours (P<0.05). The levels of diamine oxidase were higher in the IGF-I group at 6 hours but lower than those in the SAP group at 12 and 24 hours. The pathological score of the small intestine was lower in the IGF-I group than in the SAP group, and the difference was statistically significant at 12 and 24 hours. The pathologic changes observed under electron microscopy were better in the IGF-I group than those in the SAP group. The apoptosis index of intestinal epithelial cells was significantly decreased in the IGF-I group compared with the SAP group. Compared with the SO group, the mRNA expression levels of bax were increased at each time point in the SAP group, and were significantly decreased in the IGF-I group as compared with the SAP group at each time point (P<0.05). The expression levels of bcl-2 were weak and not different between the SO group and the SAP group (P>0.05). They were significantly increased in the IGF-I group versus the SO and SAP groups (P<0.05). The ratio of bax and bcl-2 mRNA expression levels at each time point in the SAP group were significantly higher than those in the SO group, but they were obviously decreased in the IGF-I group. CONCLUSIONS: Exogenous IGF-I seems to protect mucosal cells in the small intestine against SAP-induced apoptosis and could alleviate SAP-induced injury of the intestinal mucosa. The underlying mechanisms include enhanced mRNA expression of bcl-2 and inhibition of bax mRNA expression.

Coprinus comatus cultivated on cotton seed hull medium decomposed lignocellulose straggly and was high of absolute biological efficiency. Lignocellulose is the main carbon source for the fruiting stage of the fungus. There existed the positive correlation between the degradation rates of the cellulose and hemicellulose in the medium and the activities of extracellular CMCase (carboxymenthelcel lulase), FPase (filter paper cellulase) and HCase (hemicellu-lase), there also existed the positive correlation between the degradation rate of the lignin in the medium and the activity of extracellular laccase, but no correlation between the degradatio rate of the lignin in the medium and the activity of peroxidase. The activity of extracellular amylase was comparatively high at mycelial growth stage, and the protease activity peek was at teh time when the fruitbody matured.

A new thermophilic fungus J18 isolated from the soil samples was identified as Paecilomyces thermophila. This strain produced effectively xylanase utilizing several lignocellulosic materials in the solid-state fermentation (SSF) , and wheat straw was the best carbon source. The results of single-factor-experiment showed that the wheat straw of particle size 0. 3 mm ~ 0.45 mm, initial moisture content of 83% , initial pH of 7. 0 and cultivation temperature of 50℃were the optimal conditions for xylanase production. Under the optimized conditions, it produced 18 580 U/g dry substrate after 8 days of cultivation. Therefore, xylanase production by Paecilomyces thermophila in SSF possess great potential for commercial applications.
