Methods A total of 175 local nurses and 175 nonlocal nurses were randomly selected and investigated by SSRS and the earthquake questionnaire. Results There were no significant differences in their knowledge about the earthquake, professional identity and action (Pgt;0.05). The total and the three dimensions scores of SSRS of the two groups were lower than those of the domestic norms (Plt;0.01) except the subjective support dimensions. The total scores, objective support and subjective support dimensions scores of nonlocal group were higher than that in the local group (Plt;0.01). In coping style questionaire, there were significant differences in solving problems and retreat factor(Plt;0.01)and no significant differences in remorse, salvation and illusion(Pgt;0.05). Conclusion The earthquake affected mental health of the nurses and their psychological state need to be much concerned,especially the nonlocal ones.
ObjectiveTo investigate the methods and significance of early orthodontic treatment for class Ⅱ malocclusion with molars scissors bite.
MethodsTen patients with classⅡ malocclusion with molars scissors bite from 2011 and 2014 were selected. Study models and clinical data of them were retrospectively analyzed. Cephalometric radiographs taken before and after treatment were traced and measured. Student's t-test was used to analyze whether there was a significant difference before and after treatment.
ResultsAfter treatment, the change of SNA, S-Go/N-Me, and soft tissue facial angle was not significant(P>0.05). SNB, N-ANS, ANS-Me, and S-Go increased significantly. ANB, Y axis, H angle, lower lip to H-line, and inferior sulcus to H-line decreased significantly(P<0.05). The treatment duration was 12 months on average.
ConclusionEarly treatment of molars scissors bite and class Ⅱmalocclusion can keep the mandible and tempromandibular joint function well through occlusion guidance and muscle balance, which may prevent the exacerbation of facial deformity effectively.
ObjectiveTo observe Leber's hereditary optic neuropathy (LHON) microperimetry features, discuss its significance in diagnosis and treatment of LHON assessment. MethodsA retrospective clinical study. A total of 13 LHON patients (25 eyes) diagnosed in Department of Ophthalmology of the First Affiliated Hospital of Army Medical University from May 2015 to May 2020 (disease group) were included in the study, including 9 males (18 eyes) and 4 females (7 eyes), and beginning with the age of 15.0 (10.0, 57.0). Ten healthy volunteers (19 eyes) were selected as the normal group, including 7 males (13 eyes) and 3 females (6 eyes), aged 22.0 (6.0, 46.0) years at the first diagnosis. According to the course is divided into: asymptomatic group (carriers), subacute (<6 months), the dynamic group (6-12 months), chronic group (>12 months). There were 7, 6, 5 and 7 eyes, respectively. All eyes underwent best corrected visual acuity (BCVA) and microperimetry. BCVA test was performed using the international standard visual acuity chart, which was statistically converted to the logarithm of the minimum Angle of resolution (logMAR) visual acuity. MP-3 microperimetry was used to perform microperimetry, and the mean sensitivity (MS) values of five regions were recorded: center, superior, temporal, inferior, and nasal. Mann-Whitney U test was used for comparison between two groups, and Kruskal-Wallis H test was used for comparison between multiple groups. ResultsCompared with the normal group, MS in the center, superior, temporal, inferior and nasal of the diseased group decreased, and the differences were statistically significant (Z=-5.629, -4.906, -5.630, -5.631, -5.227; P<0.05). There were significant differences in different regions of MS between different course groups (H=12.296, 11.583, 10.110, 12.994, 8.663; P<0.05). There were significant differences in logMAR BCVA and central MS between asymptomatic group and subacute group (P=0.040, 0.007). There were significant differences in temporal, inferior and superior MS between subacute group and dynamic group (P=0.026, 0.017, 0.018). Dynamic and chronic group, MS above the difference was statistically significant (P=0.031). Idebenone treatment significantly improved visual field defects in 4 of 23 eyes. ConclusionsIn the early stage of LHON, the central visual field defect gradually progresses to the temporal, inferior and superior areas, and the temporal and inferior areas are more severe. Visual field defects reached a stable level at 6-12 months. MP-3 can assist in early diagnosis of LHON, and provide reliable basis for efficacy evaluation.
【Abstract】 Objective To investigate both incidence and mechanism attributing to steroid-associated osteonecrosisof femoral head(ONFH) using an experimental protocol with a single low-dose l i popolysaccharide (LPS) injection andsubsequently three injections of high-dose methylprednisolone (MPS). Methods Twenty-five New Zealand white rabbits with body weight of (3.0 ± 0.3) kg were divided randomly into 2 groups. In treatment group, 19 rabbits received one intravenous injection of LPS (10 μg/kg); 24 hours later, three injections of 20 mg/kg of MPS were given intramuscularly at an interval of 24 hours. Additional 6 rabbits which received normal sal ine injection at the same time point were used as controls(control group). The blood samples were collected for hematological examinations before and after LPS injection, MRI was performed on bilateral hip six weeks after last MPS injection, meanwhile, bone marrow was aspirated from femoral head region to evaluate stem cell’s activity. Bilateral femoral heads were harvested to make histopathology examination. Results All animals survived throughout the experiment period except one death on the second day after LPS injection. In the histopathological examinationfor the femoral head, ONFH+ was observed in 16 rabbits (88.9%), and the lesions were mainly in the metaphysis. In ONFH+ rabbits, micro vessels fibrous thrombosis and extravascular marrow fat cell size increasing were found around necrotic bone; The femoral heads of control group had no changes. MRI accurate ratio was 93.8% (15/16). Compared to basel ine, a significant decrease in ratio of tissue plasminogen activator/plasminogen activator inhibitor 1 and activated partial thromboplatin time, and a significant increase in ratio of low-density l ipoprotein/high-density l ipoprotein were only found in ONFH+ rabbits (P lt; 0.05). Meanwhile there was a significant decrease in the number of CFU-F (8.50 ± 9.63) compared with the control (70.17 ± 7.78, P lt; 0.05). Conclusion A single low-dose LPS injection and subsequent three injections of high-dose MPS is effective on building steroid-associated ONFH model, coagulation and l ipometabol ism abnormal ity, activity degeneration of stem cell may be the key factors of ONFH.
Acute carbon monoxide poisoning is a common and frequently occurring disease in winter and spring in China, with high disability and mortality. Delayed encephalopathy is a serious sequela after the pseudo-convalescence. Its mechanism is complex, including environmental and genetic factors, hypoxia and energy metabolism disorder, cytotoxicity and oxygen free radical damage, immune disorder and inflammatory activation, neurotransmitter disorder, brain parenchymal changes, vascular and hemorheological abnormalities, calcium overload, and cell apoptosis. At present, methods for predicting delayed encephalopathy in acute carbon monoxide poisoning include detailed inquiry of medical history, laboratory examination of relevant indicators, electrophysiological examination, brain imaging examination, and evaluation scale prediction. This review summarizes the research status of the pathogenesis and early prediction methods of delayed encephalopathy in acute carbon monoxide poisoning, with a view to providing reference for future research directions.
Objective
To investigate the risk factors of early allograft dysfunction (EAD) following C-Ⅱ donation after cardiac death (DCD) liver transplantation.
Methods
The data of 46 donors and recipients of C-ⅡDCD liver transplantation between March 2012 and August 2015 were retrospectively analyzed. The baseline data such as democracy, death cause, donor warm ischemic time (DWIT) and cold ischemic time (CIT) in EAD group and the non-EAD group (control group) was compared, and whether these factors were risk factors of EAD was investigated by univariate and multivariate analyses. Statistical cut-off values for significant factors of the unfavorable analysis were defined by receiver operating characteristics (ROC) analysis. The 6-month and 1-year graft survival rate were compared.
Results
The EAD group had a longer DWIT compared with the group [(17.6±4.7) and (12.7±6.2) minutes, P=0.009]; meanwhile, the EAD group had a longer CIT compared with the control group [(13.7±4.7) and (11.0±3.5) hours, P=0.020]. The other factors in both groups showed no statistical significance (P>0.05). The ROC curve revealed the cut-off values of DWIT and CIT were 17.50 minutes [area under the curve (AUC)=0.713, P=0.020] and 9.85 hours (AUC=0.723, P=0.015), respectively. The multivariate logistic regression analysis showed the DWIT [odds ratios (OR)=1.340, 95% confidence interval (CI)(1.042, 1.654), P=0.008] and CIT [OR=1.396, 95% CI (1.075, 1.698), P=0.015] were all independent risk factors of EAD. The 6-month and 1-year graft survival rate of the EAD group and the control group was 85.7% vs. 92.3% (P=0.607) and 71.4% vs. 84.6% (P=0.587), respectively.
Conclusions
EAD may occured in C-Ⅱ donors with DWIT≥17.50 minutes or CIT≥9.85 hours in DCD liver transplantation. The livers can be used as a resource for clinical use and also have a good outcome.
ObjectivesTo systematically review the differences of operative outcomes between early surgery and delayed surgery in multiple ligament injury of knee joint (MLIK) patients.MethodsPubMed, The Cochrane Library, EMbase, CNKI, CBM, WanFang Data and VIP databases were searched to collect cohort studies about operative outcomes of different surgery times in MLIK patients from inception to September 23rd, 2018. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software.ResultsA total of 8 cohort studies involving 153 early and 90 delayed operatively treated patients were included. The results of meta-analysis showed that: compared with delayed surgery, early surgery received higher Lysholm score (MD=7.52, 95%CI 2.00 to 13.04, P=0.008) and superior IKDC score rate (OR=2.97, 95%CI 1.51 to 5.84, P=0.002). There were no significant differences in Tegner score (MD=–0.08, 95%CI –1.07 to 0.92, P=0.88) and ROM (MD=4.08, 95%CI –2.38 to 10.55, P=0.22) between two groups. The main adverse reactions of MLIK included neurovascular injury, deep venous thrombosis of lower extremities, common peroneal nerve injury, tourniquet paralysis and limited joint activity. Early surgery had a lower incidence of complications than delayed surgery (7.1% vs. 30%).ConclusionThe current evidence shows that early surgery can receive higher Lysholm score and superior IKDC score rate in treatment of MLIK, and have a lower incidence of complications. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
Objective To investigate early clinical manifestations of osteogenic sarcoma to help establishment of an early diagnosis of the disease.Methods A total of 92 patients with osteogenic sarcoma in the extremities were admitted to our hospital from April 1984 to October 2002. Of the 92 patients, 71 (42 males and 29 females; averaged age 17.4 years, range 666 years; illness course 1-28 weeks) had a complete record of their medical history and examination. From their first medical visits, we obtained their clinical symptoms, physical sings, diagnoses, and duration of the delayed diagnoses. The patients were pathologically confirmed as having osteogenic sarcoma in the extremities, with the lesions located in the distal femur in 38 patients, proximal tibia in 22, proximal femur in 3, proximal fibula in 3, proximal humerus in 2, distal tibia in 2, and distalradius in 1. Results Of the 71 patients, 70 had a local pain and/or a palpable mass, 37 had a persistent pain with no difference between day and night, 23 had an intermittent pain, and 11 had a nocturnal pain. Of the 71 patients, 42 had an initial pain related to trauma, and 3 of the 42 patients had a pathologic fracture. The patients with the local mass had a delayed diagnosis of osteogenic sarcoma with a delayed duration of 1-14 weeks, averaged 4 weeks; however, the patients without the local mass had a delayed diagnosis of this disease, with a delayed duration of 3-30 weeks averaged 14 weeks. In the patients undergoing an X-ray examination at the first medical visit, the duration of the delayed diagnoses was 1-20 weeks, averaged 8 weeks, but in the patients without an X-ray examination at first, the duration was 4-30 weeks, averaged 16 weeks. Conclusion Intermittent and persistent pains and local masses are the most characteristic clinical manifestations in the early stage of osteogenic sarcoma. A history of trauma often helps to make a diagnosis of the disease. Carefulclinical examination and observation should be given to adolescent patients whohave a recurrent pain around the joint.
【Abstract】 Objective To summarize different treatments of the residual ear in auricular reconstruction, toinvestigate the reasonable appl ications of the residual ear. Methods From September 2005 to July 2006, 128 patients(79 males, 49 females; aging 5-21 years with an average of 11 years)with unilateral microtia underwent the staged repair. In the patients, there were 44 cases of left-unilaterally microtia and 84 cases of right-unilaterally microtia. The residual ears looked l ike peanut in 56 patients, l ike sausage in 35 patients, l ike boat in 27 patients, and l ike shells in 10 patients. Among all the patients, the external acoustic meatus was normal in 5 patients, stenosis in 11 patients, and atresia in 112 patients. According to auricular developmental condition, the patients were divided into three types: 17 cases of type I, 98 cases of type II, and 13 cases of type III. In the first stage operation, a 50 mL kidney-l iked expander was implanted into post aurem subcutaneous tissue. The residualear whose superior extremity was close to the hair l ine was treated. The middle and superior part of the residual ear was cut. The redundant residual auricular cartilage was removed. In the second stage operation, the inferior part of the cartilage frame was covered by the middle and superior part of the residual ear. According to the location of the residual ear, “V-Y” plasty, “Z”-plasty and reversal of the residual ear were used to correct the location of the residual ear. In the third stage operation, the remained residual ear was used to reconstruct crus of hel ix or cover the wound surface which was resulted from repairing the reconstructed ear. Results The residual ears which were reshaped and transferred had good blood circulation. All residual ears were survival. The wounds healed by first intention. The follow-up for 8-15 months showed that the auricular lobule of the reconstructed ear was turgor vital is and natural. The locations of the reconstructed ear and normal side ear were symmetry. The auricular lobules of the reconstructed ear survived well. The reconstructed crus of hel ix, hel ix, antihel ix and triangular fossawere clear. The results were satisfactory. Conclusion Using residual ear reasonably is an important procedure of successful auricular reconstruction and the symmetry of the reconstructed ear and uninjured side ear.
