Objective To detect the expression pattern of microRNA in A549 cells treated by lipopolysaccharide, study the expression of miRNA-1247-3P in A549 cells under LPS treatment and explore the possible mechanism of miRNA-1247-3P in A549 cells under LPS treatment. Methods A549 cells were divided into experimental and control groups. Immunocytochemical method and RT-PCR were used to detect the changes of SP-A and SP-C. The expression of miRNAs were detected using miRNAs array in different groups. The key miR-1247-3P was collected to detect the changes of miR-1247-3P in all groups using quantitative real-time polymerase chain reaction. Results Compared with control group, the expressions of SP-A and SP-C were significantly decreased in the experimental groups (P < 0.05). MiRNA array showed that 31 miRNAs were up-regulated and 3 miRNAs were down-regulated. Compared with control group, the expression of miR-1247-3P was significantly increased in the experimental groups (P < 0.05). Conclusion The increased expression of miR-1247-3P may play an important role in the pathogenesis of ARDS.

BACKGROUND:Posterior maleolar fractures are often accompanied by ankle joint instability,if the stability of ankle joint is not recovered,it is prone to traumatic arthritis of the ankle.However,the indications of internal fixation of posterior maleolar fractures remain controversial.OBJECTIVE:To explore the indications for internal fixation of posterior maleolar fractures by comparing the clinical effects of posterior maleolar fractures treated with internal fixation or not.METHODS:42 patients with maleolar fractures involving posterior ankle were recruited from the First Affiliated Hospital of Chongqing Medical University from January 2007 to January 2012.According to preoperative CT scans of ankle joint,42 cases were divided into the internal fixation group and the non-fixation group.27 cases in the fixation group had posterior maleolar fractures in more than 10％of the distal tibial articular surface and/or dislocation of the posterior maleolar fractures greater than 2 mm,and were treated with screws.15 cases in the non-fixation group had posterior maleolar fractures in less than 10％of the distal tibial articular surface anddislocation of the posterior maleolar fractures less than 2 mm,and were treated with non-operation.The average healing time of posterior maleolar fractures,postoperative complications,ankle-hindfoot scores of American Orthopedic Foot and Ankle Society were compared during the folow-up postoperatively.RESULTS AND CONCLUSION:Al of 42 patients with ankle fractures achieved bony union within 6 months.In the fixation group,1 case had postoperative superficial infection of the wounds in the medial ankle and lateral ankle,and the wound got healed completely with anti-infection therapy.One case in each group had postoperative superficial necrosis in the incisional edges,and got healed by dress changing.For the other cases,there was no wound infection,internal fixation loosening,breakage or failure and other adverse events during the folow-ups.Ankle functions were evaluated one year after operations according to the ankle-hindfoot score standard of American Orthopedic Foot and Ankle Society.The score of the fixation group was (83.74±10.35) points,with excelent ankle functions in 10 cases,good in 12 cases,fair in 5 cases,and no poor case,and the rate of patients achieving excelent and good ankle functions reached 82％; the score of non-fixation group was (85.60±10.40) points,with excelent ankle functions in 7 cases,good in 5 cases,fair in 3 cases and no poor case.The rate of patients achieving excelent and good ankle functions reached 80％.The ankle function evaluation results of both groups showed no statistical difference (P＞0.05).It is reasonable to consider posterior maleolar fractures is higher than 10％of the distal tibial articular surface and/or dislocation of the posterior maleolar fractures greater than 2 mm as the indications for internal fixation of posterior maleolar fractures.

Objective To study cost-effectiveness of primary cerebral infarction patients. Methods The neural function of primary cerebral infarction patients was studied by the National Institutes of Health Stroke Scale (NIHSS) with rank test and multiple regression analysis. Results After treatment in hospitals of different grades, no obvious difference was detected in the NIHSS score, but difference was found in therapy cost and therapy time; the NIHSS score and therapy time of primary cerebral infarction patients in different attack positions were obviously different, but therapy cost had no significant statistical difference. The NIHSS score of primary cerebral infarction patients with different treatments was obviously different, but therapy cost and therapy time was not. Conclusions Patients are advised to choose grade hospitals in nearby cities for treatment. Clinician are expected to choose low-cost treatment plan to relieve patients' economic burden.

The original strain was treated with UV combining LiCl. The total carotenoid yield of the strain UL-61 was 7.62mg/L, the maximal yield of astaxanthin had reached 616.8?g/g under 25℃. 8 variables including fermentation temperature, initial pH were optimized by Plackett-Burman design and Response Surface Analysis of SAS software. The temperature, initial pH and corn steep liquor were the major factors. The optimal conditions were predictted to be 16.78℃, pH4.73 and 7.06 mg/L, respectively. Under these conditions, the theroretical maximal yield of carotenoid was 3.9407 mg/L and the practical maximal yield was about 3.9261mg/L. The carotenoid production was increased by 20.4% when Phaffia rhodozyma was cultivated under the optimal conditions as compared with the control.
