PN group was given total parenteral nutrition(TPN),125 kJ/(kg?d) of energy, nitrogen intake:0.20g/(kg?d). In EN group, the naso intestinal tube was placed posterior to ligament Treitz. Since the 1st day nutrilion was infused.Results On the first?4th day, the serum RBP?PA levels were obviously decreased (P

Objective To investigate surgical treatment methods of the patients with severe acute pancreatitis complicated pancreatit necrosis (IPN) and pancreatic abscess (PA). Methods The operation of removing pancreatic abscess,infected necrosis tissues in the pancreas and peripancreatic tissues were performed. Additional, abdominal cavity infusion and drainage also were performed.Results 12 patients with IPN and 3 patients with PA were cured. Four times of operation was performed in a paitents with IPN and his corpus vertebras are infected and destructed. Another patients was relapsed after 1 year and was again performed 2 times of operation. The patient is in the stage of recovery.Conclusions IPN and PA are severe complications of severe acute pancreatitis. If image examination were showed that hydrops could not be extincted in the pancreas and peripancreas, operative therapy should be performed.

AIM: To establish a HSP90 highly expressing cell line and study the effect of high level of HSP90 on cell stress response. METHODS: The recombined plasimid pSmycHSP, which contains the full length DNA coding for human HSP90?, was introduced into mouse fibroblast cell line NIH-3T3 by electroporation after being subcloned, purified and identified by limited enzyme digestion. Screened by G418, the positive clones were selected and identified by immunofluorescence, immunocytochemistry and Western-blotting. NIH-3T3 cells transfected with empty plasmid served as control, hyperthermia(44 ℃, 20 min, 40 min)was used to simulate oxidative stress. The activity of lactate dehydrogenase (LDH) in supernatant and damage of DNA were detected by automatic biochemistry analyzer and flow cytometer separately to analyze the effect of high-level HSP90 on cell membrane and DNA injuries under stress condition. RESULTS: The rising level of HSP90 was shown by immunofluorescence, immunocytochemistry and Western-blotting in HSP90 overexpressing cell line. There was no difference in the leakage of LDH between HSP90 overexpressing cell line and control, but the damage of DNA was more severe at 44 ℃for 20 min in HSP90 overexpressing cell line than control. Compared with control, the above indices were relieved at 44 ℃ for 40 min in HSP90 overexpressing cell line. CONCLUSION: The NIH-3T3 derived cell line, which stably expressed high level of HSP90, was established. The effect of high-level HSP90 on cells is complex at different intensity of stress, and the protection may be shown at more severe stress circumstance.

CONCLUSIONS We should make heavier prevention and treatment measures in front of target population and their high risk factors and the related rings,so that we can get the real effects.

Objective To explore the clinical and molecular-genetic features and prognosis of mitochondrial encephalopathy in children. Methods A total of 11 patients diagnosed with mitochondrial encephalopathy were collected from 2008 to 2013 in Chinese PLA General Hospital, Department of Pediatrics. The clinical manifestations, laboratory tests, muscle pathology and mitochondrial gene sequencing in patients were analyzed and followed-up. Results The onset age of the patients ranged from 6 months to 12 years with the duration of disease from 2 months to 3 years. Of the 11 patients, 6 cases were diagnosed with mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS), 5 cases with mitochondrial disorder induced by mitochondrial respiratory chain enzyme deifciency. Main manifestations included convulsions, vomiting, headache, mental retardation, paralysis, etc. 10 patients had elevated lactate, and 7 patients had elevated pyruvate;6 cases showed increased slow wave in EEG background;Cranial MRI showed the damage involved in bilateral basal ganglia in 2 cases, temporal and occipital lobes in 3 cases, , multiple lesions in 2 cases, frontal and parietal occipital lobes in one patient and hypothalamus in one patient;3 patients were underwent MRA examination, 2 cases were normal, the other showed less shunts in contralateral left artery in the brain;3 cases who underwent MRS showed lactate peak. 2 cases of children underwent skeletal muscle biopsy, and one case showed abnormal mitochondria accumulation. Mitochondrial respiratory chain complex (I~V) defects test showed complex IV defects in 2 cases, complex V defects in 1 case, and combined defects of complex I+III in 2 case. 5 cases were found with mitochondrial DNA mutations in different sites of white blood cells including T8993G, T8993C, A3243G and 11,777 mutations. Conclusions Clinical manifestation of mitochondrial encephalopathy in children is strongly heterogeneous. Laboratory tests, brain imaging, gene mutation and respiratory chain enzyme examination can help to make early diagnosis and treatment. These diseases have poor prognosis.
