Objective To retrospectively review the mortality and morbidity after orthopedic surgery for aged patients with reference to orthopedic version physiological and operative severity score for the enumeration of mortality and morbidity (O-POSSUM) and Portsmouth POSSUM (P-POSSUM) and validate the score' s accuracy in operative risk prediction.Methods O-POSSUM and P-POSSUM for mortality and morbidity were applied to 839 aged patients who had undergone orthopedic surgery between January 2008 and December 2011.Observed mortality and morbidity were compared with the expected values.Results O-POSSUM predicted 230 morbidities,but the observed value was 182 (x2 =2.718,P ＞ 0.05).O-POSSUM predicted 46 deaths,higher than the observed 3 deaths (x2 =38.870,P＜0.01).P-POSSUM predicted 16 deaths,higher than the observed 3 deaths (x2 =8.997,P ＜ 0.01).Conclusions O-POSSUM accurately predicts postoperative morbidity in aged orthopedic patients.However,O-POSSUM and P-POSSUM overpredicts the mortality and should be used with caution.

ObjectiveTo observe effects of early rehabilitation and hyperbaric oxygen treatments on stroke patients.Methods80 patients were randomly divided into rehabilitation group (40 cases) and control group (40 cases). Patients in rehabilitation group were treated with rehabilitation and hyperbaric oxygen treatments; patients in control group were treated only with hyperbaric oxygen treatment. The activities of daily living (ADL) were assessed by modified Barthel index (MBI), and the cognition function was measured by mimi-mental state examination (MMSE).ResultsAfter treatment the scores of MMSE and MBI of two groups increased (P<0.05) and scores of rehabilitation group were higher than that of control group (P<0.05); the process of scores in rehabibilitation group were obviously superior to that in control group (P<0.001).ConclusionEarly rehabilitation and hyperbaric oxygen treatments can obviously improve cognition function and ADL of stroke patients.

OBJECTIVETo compare clinical outcomes of minimally invasive percutaneous plate osteosynthesis (MIPPO) in treating distal tibial comminuted fractures at early and delayed stage.

METHODSFrom January 2006 to January 2012,66 patients with distal tibial comminuted fractures were treated by MIPPO. All patients were divided into primary group and delayed group according to operation time. There were 31 patients in primary group, including 18 males and 13 females aged 21 to 57 years old with an average of (39.0 +/- 17.8), treated by MIPPO at primary stage,according to Tscherne soft tissue injury, 18 cases were grade I ,12 cases were grade II and 1 case were grade III. Thirty-five patients were treated by MIPPO at delayed stage, including 16 males and 19 females aged 24 to 55 years old with an average of (39.5 +/- 15.2), according to Tscherne soft tissue injury, 6 cases were grade I, 26 cases were grade II and 3 cases were grade III. Operation time, blood loss, hospital stay, fracture healing time and complications of two groups were recorded and observed, Lowa scoring of ankle joint were used to evaluated therapeutic effects at final following and AP and lateral X-rays were used to evaluated fracture reduction and alignment.

RESULTSAll patients were followed up, the time of following-up of primary group was (13.5 +/- 3.5) months, (15.2 +/- 3.8) months in delayed group, there was no significant meaning between two groups (t = 1.882, P = 0.064). There was no significant differences between two groups in operation time and blood loss (P > 0.05), but hospital stay in primary group was shorter than that of delayed group(P<0.05). There was no significant meaning between primary group (5.5 +/- 2.8) and delayed group (6.2 +/- 3.1) in fracture healing time (t = 0.958, P = 0.342); there was no significant meaning between primary group (87.6 +/- 6.8) and delayed group (89.6 +/- 5.2) in Lowa scores at final following-up (t = 1.351, P = 0.182). Two cases occurred postoperative superficial inflammatory reaction around fibular incision in primary group, 1 case occurred postoperative superficial inflammatory reaction around fibular incision and 1 case occurred delayed deep incision infection in delayed group at four months after operation. There was no significant differences in incidence of postoperative soft tissue complications between primary group (6.5%) and delayed group (5.7%) (t = 0.016, P = 0.900).

CONCLUSIONFor distal tibial comminuted fractures with grade I and II of Tscherne soft tissue injury, MIPPO at primary stage can not increase incidence of soft tissue complications, also can obtain the same clinical outcomes just like delayed MIPPO.

Objective To investigate the expressions and clinical significanees of suppressors of cytokine signaling-1 (SOCS-1) and SOCS-3 in myocardium of patients with sudden cardiac death (SCD). Method This study included myocardial autopsy specimens of 24 patients admitted between 2005 and 2006. Of them, 9 cases had the findings of autopsy examination consistent with coronary atberosclerosis (non-myocardial infarction) leading to SCD (non-MI group), 7 patients died of acute myocardial infarction (MI group) and 8 patients died of traffic accidents and trauma The expressions of SOCS-1 mRNA and SOCS-3 mRNA in the myocardium of non-MI and con-trol group were detected by using RT-PCR. The levels of SOCS-1 protein and SOCS-3 protein were detected by us-ing immunohistochemistry. Statistical analysis were performed by using SPSS version 13.0 software and the data were processed with ANOVA test. Results The expressions of SOCS-1 mRNA and SOCS-3 mRNA in non-MI and MI groups were were significantly higher than those in control group (0. 788±0. 101) and (0. 741±0.111) vs.(0.436±0.044) (P <0.01); (0.841±0.092) and (0.776±0.070) vs.(0.454±0.076), P <0.01, re-spectively). The antibody-positive cells of SOCS-1 protein in myocardium of non-MI group and MI group were significantly higher than those in myoeardium of control group (320.00±48.48) and (347.14±70.88) vs.(42.50±10.35) (P < 0.01), respectively. The antibody-positive cells of SOCS-3 protein in myoeardium of non-MI group and MI group were significantly higher than those in myocardium of control group (381.11±59.25) vs.(40.00±10.69), (P < 0.01)and (332.86±111.91) vs. (40.00±10.69), (P =0.001). Conclusions The expressions of SOCS rnRNA and SOCS-3 mRNA in myoeardium of patients with SCD from coronary diseases are significantly increased contributing to the pathogenesis of SCD.

Baculoviruses produce two viral phenotypes, the budded virus (BV) and the occlusion-derived virus (ODV). ODVs are released from occlusion bodies in the midgut where they initiate a primary infection. Due to the lack of an in vitro system, the molecular mechanism of ODV infection is still unclear. Here we present data demonstrating that Helicoverpa armigera nucleopolyhedrovirus (HearNPV) ODV infected cultured Hz-AM1 cells in a pH dependent manner. The optimal pH for ODV infection was 8.5, which is same to that in the microvilli of midgut epithelial cells, the ODV native infection sites. Antibodies neutralization analysis indicated that four HearNPV oral infection essential genes p74, pif-1, pif-2 and pif-3 are also essential for HearNPV ODV infection in vitro. Thus, HearNPV-HzAM1 system can be used to analyze the mechanism of ODV entry.
