Abstract?AIM: To observe the effects of different antidiabetic therapies on macular thickness in diabetes patients without fundus complication.?METHODS: The macular thickness was measured by optical coherence tomography ( OCT) .The retina volume on the center of macula was scanned, and it generated automatically the average thickness data of three rings and nine areas of 1mm, 3mm and 6mm.The data were statistically analyzed.?RESULTS: Healthy control group, oral hypoglycemic drug group and insulin treatment group were enrolled. Each group included 22 cases 22 eyes.The macular retinal thickness of healthy control group is 268.09±17.97μm (the 1st ring), 340.41 ±22.25μm ( the 2nd ring) and 298.14 ± 12.90μm ( the 3 rd ring ) , respectively. The macular thickness of oral hypoglycemic drug group is 260.00 ± 18.17μm (the 1st ring), 335.44±21.12μm (the 2nd ring) and 295.63 ±15.92μm ( the 3rd ring), respectively.The macular thickness of insulin therapy group is 271.01 ± 26.09μm (the 1st ring), 340.86±17.10μm (the 2nd ring) and 298.57 ±12.14μm ( the 3rd ring ), respectively. Comparison of the macular thickness of the 1st ring among 3 groups was insignificant (F=1.21, P=0.31), neither the comparison of the 2nd ring (F=0.35, P=0.71), neither the comparison of the 3rd ring (F=0.22, P=0.81).? CONCLUSION: Compared with healthy individuals, both oral antidiabetic medicines and insulin therapy don't alter the macular thickness of patients with diabetes while without fundus complication.

ObjectiveTo investigate the effect of the immunotherapy of CIK cell, LAK cell and PBLS cell mediated by anti-EGFR/anti-CD3 bispecific antibody (BsAb) respectively on the mice borne human gastric cancer and provide experimental evidence for therapeutic strategy in treating gastric cancer. Methods The mAbs of anti-CD3 and anti-EGFR were cross-linked to prepare the BsAb by chemical synthesis. The experimental therapy on the mice borne SGC7901 human gastric cancer was performed,and then the comparisons of the curative activity among the CIK group, LAK group and PBLS group were conducted in vivo. ResultsThe mean tumor reduction rate of the administration of CIK cells directed by anti-EGFR/anti-CD3 BsAb was(64.9±7.7)％ and higher than those of LAK cells or PBLS targeted by anti-EGFR/anti-CD3 BsAb [(43.5±8.2) ％ and (39.7±6.5) ％] (P ＜ 0.05).The mean tumor weight of the administration of CIK cells directed by anti-EGFR/anti-CD3 BsAb was (473.9±37.7) mg at the end of therapy and was lower than those of LAK cells or PBLS targeted by anti-EGFR/anti-CD3 BsAb [(764.6±88.3) mg and (829.1±104.4) mg](P ＜ 0.05). ConclusionThe CIK cell mediated by anti-EGFR/anti-CD3 BsAb could have better curative effect than other effector cells on gastric cancer in vivo.

Objective To study the clinical characteristics of the surgical treatment of cardiac valve disease in elderly patients.Methods Between January 2004 and February 2009,43 patients aged ≥65 underwent cardiac valve operation were enrolled as elderly group,85 patients aged <65 underwent the same operation served as control group in the same period,analyzed the clinical characteristics and difference between the two groups.Results The mortality of elderly group was higher than that of control group [11.6%(5/43) vs 2.4% (2/85),P<0.05].In elderly group,the duration of staying in ICU [(73.8±15.9) h],mechanical ventilation [(40.4±10.1)h],postoperative hospitalization time [(23.7±6.3) d]and the morbidity of postoperative complications [23.3%(10/43)]were higher than those of control group [(43.1±8.6)h,(28.5±5.8) h,(15.6±3.8) d,5.9%(5/85)](P<0.05 or <0.01).Conclusions Although there are high risks in patients aged 65 years and elderly with cardiac valve disease,the treatment results would be satisfactory ff select the right operating time and do full preparation with reasonable surgery strategy,the mortality and morbidity of postoperative complications could be reduced.

Objective To investigate the distribution and expression of trefoil factor 3(TFF3) in the eosinophilic cells and basophilic cells in the pars distalis of the rat pituitary .Methods The immunohistochemiscal staining technique was used to show the coexpression of TFF3/growth hormone (GH),TFF3/prolactin (PRL),TFF3/thyrotroph (TSH), TFF3/adrenocorticotropin (ACTH),TFF3/follicle stimulating hormone (FSH),TFF3/luteinizing hormone (LH) in two contiguous slices .Results The immunoreactive products of TFF 3 and chromophil cells were brown granules , mainly expressed in cytoplasm .ACTH positive signals were expressed in the cell membrane and mainly located in the pars distalis hypophyseos.TFF3 existed in parts of GH,PRL,TSH,ACTH,FSH and LH cells in contiguous slices, accounting for 19.4%, 22.4%, 9.2%, 6.5%, 35.7%, 8.3%, respectively , in which FSH was the most , PRL and GH were less . Conclusion TFF3 expresses in GH, PRL, TSH, ACTH, FSH, and LH cells in the pars distalis , which enriches the morphological data for the location of TFF 3 in gland cells of pars distalis hypophyseos .

Objective To explore the nursing experience of the safe intra-hospital transport of patients with the severe aspiration of the inhalation injury. Method The nursing measures for the intra-hospital transport of 2 cases of smoke pot inhalation injury caused by extracorporeal membrane oxygenation treatment were taken, including disease risk assessment, preparation for transport, organization of a transport team, effective vital signs monitoring during transport, extracorporeal membrane oxygenation (ECMO) pipeline monitoring and nursing and observation and nursing of complications. Result No emergency was found during the transport of patients and both of them were safely transported. Conclusion Such nursing measures as pre-transport assessment and preparation and bettering predictive nursing for the patients with severe inhalation pulmonary injury treated with extracorporeal membrane oxygenation are key to the safety during intra-hospital transport.

Aim To investigate the effects of isoliquiritigenin(ISL) on cognition dysfunction and brain energy metabolism following repeated cerebral ischemia-reperfusion in mice.Methods Mouse models of learning and memory deficits were made by repeated occlusion of bilateral common carotid arteries and reperfusion. Step-down test and Y-maze task were used to examine the learning and memory abilities of mice. The brain energy state was analyzed by reversed-phase high performance liquid chromatogra phy. Results ISL 10, 20 and 40 mg?kg -1 ig reduced the n umber of errors and extended the latency of memory in step-down test, decreased the number of cumulated stimulation and increased the number of right choices i n Y-maze task. ISL(10, 20, 40 mg?kg -1) increased the levels of ATP, ener gy charge (EC) and total adenine nucleotides(TAN) in a dose-dependent manner. Conclusion The results suggest that ISL improves cognition dysfun ction induced by repeated cerebral ischemia-reperfusion in mice, which may be r elated to the improvement of brain energy metabolism.

Objective To optimize the processing conditions of Manchuiran Dutchmanspipe Stem with alkali. Methods The combination of radial basis function ( RBF) and response surface methodology ( RSM) was used to investigate the influence of NaHCO3 , concentration, duration and cycles of processing on the content of aristolochic acid. Results The optimal process was achieved when Manchuiran Dutchmanspipe Stem was soaked for 3 cycles in 0. 05 mol·L-1 NaHCO3 solution, for 24 hours in each cycle. The removal rate of total aristolochic acid approached to 83. 74%. Conclusion The combination of RBF and RSM provided a new method and good guidance for further toxicity attenuation for Manchuiran Dutchmanspipe Stem.
