BACKGROUND: How to establish a stable in vitro culture system, including location of corneal limbal epithelial stem cells, in vitro sample harvest, in vitro culture, vector selection, as well as identification methods, play a key role in corneal limbal epithelial stem cells culture. OBJECTIVE: To culture the isolated rabbit corneal limbal epithelial stem cells and to identify the biological properties of cultured cells. METHODS: The primary rabbit cornel limbal epithelial stem cells were isolated and cultured with tissue inoculation using human amniotic membrane as vector. The growth features of cells were observed under an inverted microscope. The morphology of cells was observed by hematoxylin-eosin staining and a scanning electron microscope. Furthermore, the monoclonal antibody AE5 and P63 two-step immunohistochemical staining were used to identify limbal epithelial stem cell protein expression. RESULTS AND CONCLUSION: The rabbit corneal limbal epithelial stem cells could be successfully cultured and maintained a relatively high value-added potential in vitro. Rabbit corneal limbal epithelial stem cells cultured on the amniotic membrane pull netted cellular layer. The AE5 monoclonal antibody positive rate of primary cultured cells was about 5% and P63 monoclonal antibody positive up to 90%. AE5-positive rate increased and P63-positive rate decreased with the increase in the number of subculture. The rabbit limbal epithelial stem cells can be successful culture and amplified on human amniotic membrane in vitro by limbal tissue culture method. The cultured cells maintain the characteristics of corneal epithelial cells. The rabbit corneal limbal epithelial stem cells can form grafts on the amniotic membrane.

Objective To design and testify a novel strategy for acquiring mimetic epitope mapping by screening for a phage random peptide library using polyclonal anti keratin autoantibodies (AK auto Ab). Methods AK auto Ab were isolated and purified from pooled human sera by keratin affinity column in which keratin had been linked with CNBr Sepharose 4B,then biotinylated by the biotin ester. A 15 mer phage random peptide library was biopanned for 3 cycles and positive clones were identified by ELISA,competition assay and DNA sequencing. ResultsBy sequence comparison 23 positive clones were selected randomly and three epitopes were confirmed. Among the three epitopes SLSPMPTTNRR was the dominant epitope. The phages carrying positive clones reacted with AK auto Ab specifically and keratin could prevent interaction between AK auto Ab and positive phages. Conclusion The designed strategy is successfully applied in acquiring epitopes of polyclonal autoantibodies to keratin, which could provide a new approach for the discovery of epitope mapping which binds to natural autoantibodies.

Objective To observe the clinical efficacy of ulinastatin(UT) conjoined to high flow continuous blood purification( CBP) in the critical patients with multiple organ dysfunction syndrome(MODS). To evaluate the therapeutic potential of UT and CBP in systemic inflammatory response syndrome (SIRS) , severe sepsis( SS) , acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). Method A total of 122 cases of emergency and critical patients with a score of more than 15 counted up from APACHE H (acute physiology and chronic health evaluation 11 ) were randomly divided into Ulinastatin treatment group (UT group, n = 35) .continuous blood pu-rification(CBP group, n = 31),UT plus CBP (combine group, n = 30) and routine treatment group (control group, n =26). Routine treatment was given to patients of all groups, and patients of UT group had Ulinastatin 0.4 MIU given intravenously every 8 hours for 7 days in addition. Patients of CBP group were managed with continuous blood purification round the clock for 7 days and those of combine group were treated with UT plus CBP for 7 days.The efficacy of the treatment in four groups was assessed,and serum high sensivity reactive protein(hs-CRP) and IL-6 levels were measured on admission and comparison was made between values of biomarkers taken before and 1 d,3 d,and 7 d after treatment in four groups. The changes in WBCs,arterial gas analysis and the oxygena-tion index PaO2/FiO2 were checked, and at the same time, the APACHE II values and the incidence of MODS were compared within four groups. Results (1)One, three and seven days after treatment the plasma hs-CRP and IL-6 levels in UT and CBP groups were reduced significantly more than those in control group ( P < 0. 05), and in combine groups those were more dramatically lowered ( P < 0.05, P < 0.01). Before treatment there was no significance diffience in those values between groups, and there was on diffience in those values between 3 rd day and 7 th day after treatment ( P > 0.05). (2) The 1 st,3 rd and 7 th day after treatment the arterial gas PaO2/FiO2 index in UT and CBP groups was improved more than that in control group ( P < 0.05) , and it in combine group was most significant improved (P < 0.05,P < 0.01). The ALT and creatinine were lower than those in control group ( P < 0.05), and there were no significant differences in ALT and creatinine between groups before treatment (P > 0.05). (3) The 1 st,3 rd and 7th day afer treatment,the APACHE II values in UT and CBP groups were decreased more than those in control group ( P < 0. 05) , and therefore, the incidence of MODS was lower ( P < 0.05). Conclusions Ulinastatin could significantly inhibit the production of inflammatory cytokines and CBP could effectively eliminate inflammatory factors from blood, and the combination of these two approaches produce a more effective therapeutic potential for preventing MODS development.

Objective To evaluate the effects of fluid resuscitation and large-volume hemofiltration (HVHF) on the Alveolar-arterial oxygen exchange in patients with refractory septic shock. Method A total of 89 intensive care patients with refractory septic shock treated with fluid resuscitation and/or HVHF were enrolled between August 2006 and December 2009. All the patients were randomly divided into two groups. In group A, patients were treated with fluid resuscitation, n = 41 cases) and in group B, patients were treated with large-volume hemofiltration and fluid resuscitation, n =48). The O2 content of central venous blood(CcvO2), arterial oxygen content (CaO2), Alveolar-arterial oxygen pressure difference (P(A-a)DO2), the ratio of arterial oxygen pressure/alveolar oxygen pressure (PaO2/PAO2), respiratory index (RI) and oxygenation index (OI) were checked. The levels of oxygen exchange in two groups were detected by arterial blood gas analysis before treatnent, 24 hour, 72 hour and 7 days after treatment. The APACHE Ⅱ scores in patients with refractory septic shock were measured before and the 7th day after treatment with HVHF and/or fluid resuscitation respectively. Data were analyzed by using t -test and chi-square test to compare the differences and ratio between two groups and were expressed in mean ± standard deviation, and the analysis of variance was done with SPSS version 12.0 software. Results ① The differences in CcvO2 and CaO2 between two groups were[(0.60±0.24) vs. (0.72±-0.28), P <0.05 and (0.84±0.43) vs. (0.94±0.46), P <0.05]; and the oxygen extraction rates (O2ER) were significantly different between two groups [(28.7±2.4) vs. (21.7±3.4), P<0.01];② The levels of P(A-a)DO2、ratio of PaO2/PAO2、RI and OI in group B were reduced more significantly than in group A (P<0.05 or P<0.01);③The APACHE Ⅱ scores in both groups were gradually reduced after treatment for 7 days, and the APACHE Ⅱscore in group B on the 7th day of treatment were lower than that in group A[(17.2 ± 6.8) vs. (8.2 ± 3.8), P < 0.01]. Conclusions Fluid resuscitation and HVHF could improve alveolar-arterial-oxygen exchange in patients with refractory septic shock, and at the same time decreased the APACHE Ⅱ scores, improving the survival rate of patients.

Objective To identify the incidence and risk factors of gastrointestinal bleeding in patients supported with mechanical ventilation over 48 hours. Method A total of 127 ICU patients supported with mechanical ventilation for over 48 hours were enrolled from January 1, 2007 to December 31, 2008 for the retrospective study. Exclusion criteria included the history of gastrointestinal bleeding and ulcer, recent gastrointestinal surgery, brain death and active bleeding from nose or throat. Demographics of patients including age, diagnosis at admission, duration of ICU stay, duration of mechanical ventilation, pattern and parameters of ventilation, ICU mortality, A-PACHE II score, multiple organ dysfunction score, and the results of biochemical assays including renal, hepatic and coagulation functions were recorded. Risk factors of gastrointestinal bleeding were analyzed by using univariate analysis And multiple logistic-regression analysis. Results Of the 127 patients, the incidence of gastrointestinal bleeding was 41.7% . and among them 3.9% patients suffered from clinically significant bleeding. However, the independent risk factors of gastrointestinal bleeding were the peak inspiratory pressure > 30 cmH20 (RR = 3.73, 95% CI = 1.59-9.46), renal failure (RR = 1.16,95% CI = 1.02 - 2.32), PLT count <50× 109 L-1(RR = 2.67, 95% CI = 1.32 - 15.78) and prolonged APTT (RR = 4.58, 95%CI = 2.32 - 12.96). The good entetal nutrition had a beneficial effect to the avoidance of gastrointestinal bleeding ( RR = 0.30, 95% CI = 0. 13 - 0.67). Conclusions The incidence of gastrointestinal bleeding is high in patients supported with mechanical ventilation, and the bleeding usually occurs within the first 48 hours. High pressure ventilator setting, renal failure, decreased PLT count and prolonged APTT are significant risk factors of gastrointestinal bleeding. However, the good enteral nutrition is the independent protective factors.
