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.

In all the carpal fractures, scaphoid fracture is the most common in clinic (from 60% to 70% in proportion) and likely leads to nonunion. If nonunion is not treated in time, it probably causes instability of the scaphoid lunate joint, further leading to scapholunate advanced collapse. Its comprehensive manifestations include degenerative arthropathy of radial styloid process, radial scaphoid joint, capitulolunate joint and even total wrist joint, eventually leading to wrist joint dysfunction. Therefore, more and more attention has been paid to treatments of scaphoid fracture nonunion. Bone grafting is the most common practical treatment, but new surgical procedures have emerged in recent years. This article thus reviews the research advances in bone grafting for scaphoid fracture nonunion, commenting on the advantages and disadvantages of various techniques.

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.

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.

This study examined the effect of tanshinone II A (TSN II A) on the cardiac fibrosis induced by transforming growth factor β1 (TGF-β1) and the possible mechanisms. Cardiac fibroblasts were isolated from cardiac tissues of neonatal Sprague-Dawley (SD) rats by the trypsin digestion and differential adhesion method. The cells were treated with 5 ng/mL TGF-β1 alone or pretreated with TSN II A at different concentrations (10(-5) mol/L, 10(-4) mol/L). Immunocytochemistry was used for cell identification, RT-PCR for detection of the mRNA expression of connective tissue growth factor (CTGF) and collagen type I (COL I), Western blotting for detection of the protein expression of Smad7 and Smad3, and immunohistochemistry and immunofluorescence staining for detection of the protein expression of phosphorylated Smad3 (p-Smad3), CTGF and COLI. The results showed that TGF-β1 induced the expression of CTGF, COL I, p-Smad3 and Smad7 in a time-dependent manner. The mRNA expression of CTGF and COL I was significantly increased 24 h after TGF-β1 stimulation (P<0.01 for all). The protein expression of p-Smad3 and Smad7 reached a peak 1 h after TGF-β1 stimulation, much higher than the baseline level (P<0.01 for all). Pretreatment with high concentration of TSN A resulted in a decrease in the expression of p-Smad3, CTGF and COL I (P<0.01). The protein expression of Smad7 was substantially upregulated after pretreatment with two concentrations of TSN II A as compared with that at 2 h post TGF-β1 stimulation (P<0.05 for low concentration of TSN I IA; P<0.01 for high concentration of TSN II A). It was concluded that TSN II A may exert an inhibitory effect on cardiac fibrosis by upregulating the expression of Smad7, suppressing the TGF-β1-induced phosphorylation of Smad3 and partially blocking the TGF-β1-Smads signaling pathway.

Objective To explore the efficacy of two treatment methods for thoracic tuberculosis.Methods According to the different surgical methods,61 patients with thoracic tuberculosis were randomly divided into A group (31 cases) and B group (30 cases).A group was treated with simple thoracic tuberculosis soft tissue lesions removed,and B group was treated with focus removal + rib resection + muscle flap packing.The operation time,pain time,extubation time,hospital stay,wound fluid,cure rate and recurrence rate were compared between the two groups.Results The operation time,pain time,hospital stay time of A group were shorter than those of B group [(35.0 ± 11.0)minvs.(50.0 ±9.5)min,(1.8±1.3)d vs.(4.2 ±2.4)d,(12.5 ±3.4)d vs.(18.8 ±5.7)d],the differences were statistically significant (t =6.257,4.275,5.334,all P ＜ 0.05).There were no statistically significant differences in the extubation time,wound effusion,cure rate and recurrence rate between the two groups [(5.8 ± 3.1) d vs.(5.5 ± 2.8) d,2 cases vs.1 case,100.0％ vs.100.0％,6.4％ vs.3.3％,t =8.691,x2 =9.867,13.674,15.871,all P ＞ 0.05].Conclusion Analysis of the specific situation should be individualized on the chest wall tuberculosis,in the case of rib destruction,the focus should be removed + rib resection + muscle flap packing,if there is no rib destruction,simple chest wall tuberculosis soft tissue lesions removal is more safe,because it is less traumatic for patients.
