?AlM: To analyze the result of ultrasound biomicroscopy ( UBM ) of patients with rhegmatogenous retinal detachment ( RRD ) who need to perform pars plana vitrectomy ( PPV ) to explore the value of clinical application of UBM at preoperation.
?METHODS:Patients who underwent PPV for RRD in our hospital from January to December 2014 were selected. The preoperative results of UBM were recorded and the positive findings of UBM were analyzed, the value of preoperative application of UBM was investigated.
?RESULTS:Totally 356 cases (357 eyes) of patients with RRD were received PPV. All patients were examined by UBM, 122 eyes ( 34. 17%) were positive, 56 eyes were ciliochoroidal detachment, 28 eyes were narrow anterior chamber angle, 6 eyes were chamber angle-closure, 28 eyes were ciliary body cyst, 4 eyes were iris cyst, 11 eyes were anterior proliferative vitreoretinopathy, 1 eye was retinal cyst. There were 12 eyes existing two lesions at the same times. ln this study, patients with choroidal detachment was detected by UBM in 56 eyes, the positive rate was 15. 7%, while 25 eyes was detected by B -ultrasonography, the positive was 7. 0%. The difference was statistical significant(χ2=13. 382, P<0. 05).
?CONCLUSlON: The patients with RRD have underwent PPV for the condition of illness, preoperative UBM can be examined to detect the condition of anterior chamber angle, iris, ciliary and anterior choroid, which is significant for comprehensively understanding the preoperative condition of patients, estimating the difficulty of the operation, and guiding operation and the postoperative follow-up.

Objective:To explore the resource of rice bran by comparing antioxidative activities and growth promotion of Bacillus bifidus between supernatant of formented rice bran(RBF) by Bacillus natto and water extract of rice bran(RBW) . Method:The reducing capacity the?OH and ??O 2 scavenging capacity and the inhibitory effect to oxidize lard were determined in vitro. The growth promotion for Bacillus bifidus by photodensity with simulated condition was investigated in vivo. Results:RBF and RBW had antioxidant activity in vitro. The IC50 of scavenging?OH and ??O 250 of RBF was 3.55 mg/ml and 23.5 mg/ml,0.3 and 10 folds higher than that of RBW respectively. In inhibiting oxidation of lard,RBF had a little higher antioxidative activities than RBW,near VE. RBF and RBW could promot growth of Bacillus bifidus by 65.2% and 17.8% respectively. By enzymatic digestion,the promotive rate of RBF was still 51.6%. Conclusion:RBF had higher antioxidant activity and growth promotion to Bacillus bifidus.

Objective To detect potential proteins which may play a key role in pathogenesis and early diagnosis for Acinetobacter baumannii sepsis,and compare the protein profile of neutrophils of na(i)ve rats with that of rats infected with Acinetobacter baumannii.Methods Using two-dimensional electrophoresis for separation of proteins,we compared the differences of the profile of total proteins from neutrophils of na(i)ve rats with that of rats infected with Acinetobacter baumannii.Differences in the profiles of expressed proteins were observed,and some of the proteins were isolated and verified by line mass spectrometry analysis and Western blot.Results Fifty proteins from the neutrophils of rats with Acinetobacter baumannii sepsis were found to be different from those of naive rats.Forty-one of these proteins were able to be identified successfully using two-dimensional electrophoresis,in which 24 were upregulated,and 17 were downregulated compared with the proteins isolated from neutrophils of na(i)ve rats.Conclusion The protein profile of neutrophils in rats with Acinetobacter baumannii sepsis is significantly different from that of na(i)ve rats.These proteins can be identified by proteomic screening,and may be used as potential markers for early diagnosis and molecular targets for effective treatment of Acinetobacter baumannii sepsis.
