Methods Thirty cases of hepatic carcinoma with gastroesophageal variceal hemorrhage diagnosed with gastroscopy between January 2008 and June 2015 in Chinese PLA General Hospital and Hainan branch were included. Patients′ clinical data, complications and therapeutic effects of endoscopy were retrospectively analyzed. Results All patients underwent endoscopy successfully. No recurrent bleeding was found in any case after treatment. Eight cases of varicosis nearly disappeared. Six?month follow?up showed three cases of gastrointestinal bleeding, one case of death of bleeding, and no recurrence hemorrhage in 27 others. Conclusion Endoscopic treatment could safely and effectively control the primary liver cancer combined with gastroesophageal variceal hemorrhage, hence may provide opportunity for further treatment of liver cancer.

Objective To investigate the difference among neonatal rat models of hypoxia-ischemia induced white matter injury of brain by three different methods and to provide theory basis on choosing the proper animal model for deep study on white matter injury of premature infants.Methods Three different hypoxia-ischemia methods were applied to induce brain white matter injury model of Wistar rats of postnatal 3rd day which were left carotid artery ligation followed by 6％ oxygen for 30 minutes and for 4 hours respectively,and bilateral carotid artery ligation followed by 8％ oxygen for 30 minutes.Compared brain pathological results of rats in different groups,changes in white matter of brain by glial fibrillary acidic protein (GFAP) and myelin basic protein (MBP) immunostaining,and changes in time of opening eyes and eyes appearance.Results Left carotid artery ligation followed by 6％ oxygen for 30 minutes resulted in sparse and vague periventricular white matter without necrotic lesions,and the degree of GFAP intensity [(5 021.63 ± 358.92) OD] increase and MBP intensity [(18 488.63 ± 1 822.62) OD] decrease were lowest (P ＜ 0.000 1),as well as the delay of opening time of the left eye.Left carotid artery ligation followed by 6％ oxygen for 4 hours resulted in necrotic lesions of periventricular white matter,with the degree of GFAP intensity [(6 069.13 ± 458.61) OD] and MBP intensity [(15 003.38 ± 1 559.11) OD],and also the delay of opening time of the left eye.Bilateral carotid artery ligation followed by 8％ oxygen for 30 minutes caused cystic necrosis of bilateral periventricular white matters,and the degree of GFAP intensity [(6 194.50 ±432.69) OD] increase and MBP intensity [(10 119.35 ± 735.16) OD] decrease of the left side were highest(P ＜ 0.000 1),as well as the delay of opening time and cataract in both eyes.Conclusion Left carotid artery ligation followed by 6％ oxygen for 30 minutes is more suitable for investigating mild brain white matter injury.Left carotid artery ligation followed by 6％ oxygen for 4 hours and bilateral carotid artery ligation followed by 8％ oxygen for 30 minutes are more proper for the investigation of severe periventricular leukemacia cases.

avian influenza virus (AIV) can not only infect avian and cause pandemics,but also result infection and initiate pandemics in humans and other mammal animals,crossing the species barrier.There have been some advance in research into the nonspecific species barrier of human respiratory tract against AIV infection and the mechanism of the infection of AIV in humans in recent years.

An extracellar fibrinolytic strain was isolated from fermented shrimp paste. In addition to general physiological and biochemical properties, the strain was identified by 16S rDNA sequence and systematic analysis. The results showed that 16S rDNA sequence of the strain had high similarity with AY601723 and AB195282, suggesting that the strain is a subspecies of Bacillus sp. It was named as Bacillus sp. nov. SK006 by CCTCC. The medium composition and fermentation conditions for fibrinolytic enzyme production were also optimized in the research.

BACKGROUND: This study aimed to observe the effect of early goal directed therapy (EGDT) on tissue perfusion, microcirculation and tissue oxygenation in patients with septic shock. METHODS: Patients with early septic shock (<24 hours) who had been admitted to the ICU of Zhongda Hospital Affiliated to Southeast University from September 2009 through May 2011 were enrolled (research time: 12 months), and they didn't meet the criteria of EGDT. Patients who had one of the following were excluded: stroke, brain injury, other types of shock, severe heart failure, acute myocardial infarction, age below 18 years, pregnancy, end-stage disease, cardiac arrest, extensive burns, oral bleeding, difficulty in opening the mouth, and the onset of septic shock beyond 24 hours. Patients treated with the standard protocol of EGDT were included. Transcutaneous pressure of oxygen and carbon dioxide (PtcO2, PtcCO2) were monitored and hemodynamic measurements were obtained. Side-stream dark field (SDF) imaging device was applied to obtain sublingual microcirculation. Hemodynamics, tissue oxygen, and sublingual microcirculation were compared before and after EGDT. If the variable meets the normal distribution, Student's t test was applied. Otherwise, Wilcoxon's rank-sum test was used. Correlation between variables was analyzed with Pearson's product-moment correlation coefficient method. RESULTS: Twenty patients were involved, but one patient wasn't analyzed because he didn't meet the EGDT criteria. PtcO2 and PtcCO2 were monitored in 19 patients, of whom sublingual microcirculation was obtained. After EGDT, PtcO2 increased from 62.7±24.0 mmHg to 78.0±30.9 mmHg (P<0.05) and tissue oxygenation index (PtcO2/FiO2) was 110.7±60.4 mmHg before EGDT and 141.6±78.2 mmHg after EGDT (P<0.05). The difference between PtcCO2 and PCO2 decreased significantly after EGDT (P<0.05). The density of perfused small vessels (PPV) and microcirculatory flow index of small vessels (MFI) tended to increase, but there were no significant differences between them (P>0.05). PtcO2, PtcO2/FiO2, and PtcCO2 were not linearly related to central venous saturation, lactate, oxygen delivery, and oxygen consumption (P>0.05). CONCLUSION: Peripheral perfusion was improved after EGDT in patients with septic shock, and it was not exactly reflected by the index of systemic perfusion.

Objective To identify serum biomarkers for rheumatoid arthritis(RA)by protein finger- print pattern. Methods One hundred and forty-one serum samples of 90 RA patients, 20 systemic lupus ery- thematosus(SLE)patients, and 31 healthy individuals were randomly divided into training set(n=93, 60 RA patients, 13 SLE patients and 20 healthy individuals)and test set(n=48, 30 RA patients, 7 SLE patients and 11 healthy individuals). They were detected by surface enhanced laser desorption/ionization-time of flight- mass spectrometry(SELDI-TOF-MS). The protein fingerprint pattern obtained from SELDI-TOF was trained by a multi-layer artificial neural network(ANN)to establish a diagnostic model. Results The detective mod- el obtained by ANN was used to detect the 48 unknown serum samples. The sensitivity and specificity for RA detection was 90% and 90.9% respectively. Conclusion In comparison with traditional methods, SELDI- TOF-MS could identify new serum biomarkers in RA. Combined with ANN, it provides high sensitivity and specificity for RA diagnosis.
