Objective To explore the response inhibition ability of oppositional defiant disorder symptoms children. Methods Subjects were 27 oppositional defiant disorder symptoms children and 27 normal children. They were asked to complete the stop signal task,go/no go task and the Simon task. Results The delay time of stop reaction (SOA,(260.27 ±69.12)ms) and go reaction time( (554.31 ±55. 81 )ms)of the oppositional defiant disorder symptoms children were shorter than the control group, the difference was significant (P＜0. 05). However,the stop reaction and interference control ability were no significant difference between these two groups. Conclusion Oppositional Defiant Disorder symptoms children's poor prepotent response inhibition ability is cognitive mechanism of their impulsive behaviors.

Objective To evaluate the relationship between fragile fracture sites in hospitalized geriatric and nutritional status.Methods On the basis of whether the fracture,293 cases were divided into fracture group(n =140)and normal control group(n =153),51 males(36.4%)and 89 females(63.6%)in 140 fracture patients. Results The age was (74.04 ±8.58)years in the fracture group,that in the normal control group was (74.77 ± 8.14)years,there was statistically significant difference between the two groups(t =-0.743,P >0.05).The femoral neck fracture was 51 cases(36.4%)and intertrochantetic fracture was 57 cases(40.7%),and other was 32 cases (22.8%).The patients were divided into the two groups according to the age:60 ~75 years group(n =62)and >75 years group(n =78),femoral neck fracture was 37.2%,and intertrochantetic fracture was 52.6% in the group that more than 75 years old,which were 35.5% and 25.8%,respectively in 60 ~75 years group,there was statistically significant difference between the two groups(χ2 =18.337,P <0.01).The hemoglobin,serum albumin weight,weight,BMI in the fracture group were (117.44 ±20.25)g/L,(34.96 ±4.95)g/L,(60.81 ±10.63)kg,(22.83 ±3.54)kg/m2 , and those in the normal control group were (136.99 ±17.10)g/L,(37.27 ±5.85 )g/L,(64.47 ±11.23)kg, (24.24 ±3.88)kg/m2 respectively.The commonly used nutritional indicators:hemoglobin(t =-8.908),serum albu-min(t =-3.619),weight(t =-2.837)and BMI(t =-3.218)were lower than the normal control group(all P <0.01 ),serum phosphate was lower than the normal control group,the difference was statistically singnificant (t =-2.047,P <0.05).The blood calcium(t =0.630)and ALP(t =-0.550)had no statistically singnificant differences between the two groups(all P >0.05).Conclusion The proportion of intertrochantetic fracture and femo-ral neck fracture were higher in hospitalized elderly patients,and malnutrition,such as lower hemoglobin,lower serum albumin,lower weight,and lower BMI were,important factors in the fragile fracture in the geriatric inpatients.

The completion of human genome project and the progress in medical practice have inevitably lead to the development of precision medicine, which is a medical model that proposes the customization of medical care including medical decisions, practices, and/or medical products with patient's genetic background, environmental factors and life behavior being taken into account. The current work proposed precision stomatology for the first time, and by integrating data reported in recent literature, we described the current practice of precision stomatology in multiple disciplines in modem dentistry. The clinical significance of precision stomatology and its future challenges have also been discussed.

Objective To discuss the CT features and the prognosis of hypoxic ischemic encephalopathy (HIE) with intracranial hemorrhages in neonates.Methods The CT features of the HIE with intracranial hemorrhage were analyzed and follow-up studied in 64 cases.Results Of all the 64 cases with HIE, 53 cases were associated with subarachnoid hemorrhage (SAH), and all cases were normal in the follow-up study after 1 month. 1 case was associated with intraventricle hemorrhage (IVH), 10 cases were associated with mixed bleeding (SAH+IVH in 3 cases, IVH+IPH in 1 case, SAH+IPH in 2 cases, SAH+SHE in 2 cases, SAH+SDH in 2 cases). Of the follow-up studies on 10 mixed bleeding cases, 1 was normal, 1 was dead, and the others were cerebromalacia, cerebral atrophy, porencephaly and calcium.Conclusion Different intracranial hemorrhages results in different prognosis.

AIM: To select optimum purification of Qingluotongbi decoction (Caulis Sinomenii etc.). METHODS: Qingluotongbi decoction was refined respectively by ceramic membrane microfiltration, ultrafiltration, alcohol sedimentation, high speed centrifugalization, flocculation and macroporous resin absorption. Their refining effect was compared according to indexes of color, clarity, loss rate of sinomenine, removal ratio of impurity. RESULTS: All kinds of purification made decoction light and clear. Removal ratio of impurity by macroporous resin absorption was the highest and reached 80% or more. Removal ratio of impurity by ceramic membrane microfiltration was 21.17% , less than that by alcohol sedimentation or ultrafiltration, but more than that by flocculation and centrifugalization. Loss rate of sinomenine by AB 8 type macroporous resin absorption was the lowest and reached 6.39% , and that by ceramic membrane microfiltration was 15.31% , less than that by ultrafiltration, alcohol sedimentation, centrifugalization and flocculation. The chromatogram of decoction disposed by macroporous resin was different from that of decoction unsettled, but that disposed by ceramic membrane was similar to that of decoction unsettled. CONCLUSION: The technique of ceramic membrane microfiltration is optimum purification of Qingluotongbi decoction with the virtues of moderate removal ratio of impurity, small amount lose rate of sinomenine and simple process.

BACKGROUND:Intramedul ary nail fixation has more advantages in open fractures compared with the locking compression plate, such as the dual functions of lock and compression, highly protecting the blood supply in fracture end, less tissue trauma, firm elastic fixation and low infection rate. OBJECTIVE:To investigate the clinical efficacy and biomechanical properties of tibial intramedul ary nail and locking compression plate in treatment of open tibial fractures by stages. METHODS:Total y 100 patients with open tibial fractures who received treatment at the Department of Orthopedics, Jiaozhou Central Hospital of Qingdao Affiliated to Weifang Medical Col ege from January 2012 to January 2014 were enrol ed. Patients were divided into tibial intramedul ary nail group (n=57) and locking compression plate group (n=43) according to the surgical procedures using randomized control ed method. Ten corpses models of open tibial fractures provided by Jiaozhou Central Hospital of Qingdao Affiliated to Weifang Medical Col ege were selected, and then randomly divided into 2 groups. Three-point bending test, axial compression test and torsional strength test were conducted after the fixation with tibial intramedul ary nail and locking compression plate. RESULTS AND CONCLUSION:The operative time and per-operative blood loss of patients in the tibial intramedul ary nail group was significantly less than those in the locking compression plate group (P<0.05). There were no significant differences in wound infection, fixtures loosening, not healing and other complications after fixation between these two groups. There were no incision infection in these two groups. The specimens bending test offset, axial compression experiments offset and torsion test torsion angle in tibial intramedul ary nail group were significantly less than those in the locking compression plate group (P<0.05). These results demonstrate that tibial intramedul ary nail and locking compression plate for treatment of open tibial fractures by stages can achieve the desired therapeutic effect, however, the biomechanics of tibial intramedul ary nail is more stable, and more in line with the biomechanical properties of human body, with the advantages of firm fixation, doing exercises in early stage and smal stress shielding. Choosing the appropriate materials according to patient’s symptoms and fracture location during treatment can improve the curative effect.
