Objective To observe the clinical effect of locking compression plate(LCP)to treat proximal humeral fractures.Methods From October.2006 to May.2008,22 proximal humeral fractures were treated with LCP (WEGO Co.Ltd,SANDONG).Results All of 22 patients were followed up for 8-22 monthes postoperatively.All fractures healed within the period of follow up without looseness of internal fixators.The average healing time was 12.6 weeks.According to Neer' s score,12 cases were excellent,8 cases were good,the other two were fair.The excellent and good rate put together was 90.9%.Conclusion Locking compression plate fixation is a simple and reliable procedure to treat proximal humeral fractures with satisfactory effects.

OBJECTIVE:To observe the clinical efficacy of pegylated interferon α-2a(Peg-INFα-2a)combined with adefovir (ADV)in the treatment of HBeAg-positive chronic hepatitis B (CHB). METHODS:An open randomized controlled clinical trial was performed. According to random number table,70 patients with HBeAg-positive chronic hepatitis B were divided into observa-tion group and control group,with 35 cases in each group. Observation group received Peg-INF α-2a combined with ADV,and control group was treated with Peg-INF α-2a only. Therapeutic efficacy and safety evaluation were evaluated after 24 and 48 weeks of treatment. RESULTS:After 24 weeks of treatment,ALT normalization rate of observation group and control group were 51.43%and 25.71%,and HBV-DNA negative rate of 2 groups were 68.57% and 37.14% respectively,with statistical significance (P<0.05). There was no statistical significance between HBsAg negative rate and HBeAg negative rate (P>0.05). After 48 weeks of treatment,ALT normalization rate of observation group and control group were 77.14% and 54.29%,and HBeAg negative rate 54.29% and 31.43%,and HBV-DNA negative rate 82.86% and 42.86% respectively,with statistical significance(P<0.05).There was no statistical significance in HBsAg negative rate and ADR (P>0.05). CONCLUSIONS:Peg-INFα-2a combined with ADV have good clinical efficacy in the treatment of HBeAg-positive CHB,and it is better than Peg-INFα-2a monotherapy and has less ADR.

Posttraumatic stress disorder (PTSD) is a psychiatric condition that can occur in anyone who has experienced a life-threatening or violent event.Research into the underlying neurobiology has implicated dysregulation in multiple neurotransmitter systems including norepinephrine,serotonin and glutamate as well as the hypothalamic-pituitary axis.Although there was a tremendous growth in the understanding of PTSD in the past few years,the specific neurobiological underpinnings of PTSD wait for more explorations.

Objective To investigate the properties of hind foot motion and it's changes in ankle or subtalar joint arthrodesis. Methods Eight fresh frozen adult leg-foot specimens were mounted in a coordinated system, a Steinmann pin was perforated across the calcaneus as a marker. The displacements of the marked points in the coordinated system were recorded when subtalar or ankle joint was fixed respectively. Through matrix translation and Euler equation, the angle of the calcaneus rotation were calculated, representing the motion of the subtalar and ankle joints in different condition, Statistical analysis were also taken between different conditions. Results Three dimensional (3-D) motion was observed in hind foot motion. The range of motion with ankle joint fixation was: inversion 15.99??2.81?, eversion 8.62??1.90?, dorsiflexion 3.70??1.00?, plantar flexion 5.87??1.39?, adduction 7.64??2.04?, and abduction 3.99??1.78?. When subtalar joint was fixed, they were: 7.13??1.07?, 5.52??0.85?, 17.09??2.87?, 30.75??5.04?, 10.77??1.56?, and 6.54??1.88? respectively. While they were 22.62??3.21?, 40.88??5.77?, 18.87??3.89?, 9.12??2.05?, 17.48??2.26? and 11.47??2.29?, when no joint was fixed. Arthrodeses of ankle or subtalar joint would affect the hindfoot motion significantly (P

Objective To establish the method of estimating the stature with the length of the thoracic segments of spine.Methods By applying technology of digital radiography(DR),the digital radiography of thoracic segments of 514 living subjects from the population of Han of Sichuan in China are obtained,their length of thoracic segments of spine also were measured from the radiograms and the body height of each subject was recorded.Linear regression analysis in grouping was done between the length of thoracic segments of spine and body height,and than the linear regression equations for stature estimation were produced based on the dimensions of thoracic segments.Results 7 regression equations were established from 7 groups(mixture between males and females,males,females,males between 20 and 45 years of age,males greater than 45 years of age,females between 20 and 45 years of age and females greater than 45 years of age).Each equation has been checked by analysis of variance of linear regression model and proved to be appropriate in statistic(P

Objective To investigate the relationship among IGF-II expression and cell proliferation and apoptosis in human colorectal adenocarcinoma. Methods 60 paraffin embedded samples of human colorectal adenocarcinomas were used in this study. IGF-ⅡmRNA expression was detected by in situ hybridization, proliferation cell nuclear antigen(PCNA) protein was measured by immunohistochemical staining and apoptosis was determined by TUNEL technology. Fifteen normal colorectal tissues were used as controls. Computerized image analysis system qualitatively analyzed the positive ratio of above three indices in the cancer and normal tissues. Results The percentage of IGF-ⅡmRNA expression was significantly higher in colorectal adenocarcinoma (39.64%?7.32%) than that in normal colorectal tissues (23.21%?4.10%) (P

Down-regulation of adult hippocampal neurogenesis has been regarded as one of the important biological and cellular basis of depression. Recent studies have shown that there is a close correlation between neurogenesis and angiogenesis. Several angiogenesis factors, especially vascular endothelial growth factor (VEGF), play a vital role on angiogenesis. They not only have the neurotrophic and neuroprotective effects, but also up-regulate hippocampal neurogenesis. Thus,VEGF may be involved in the occurrence and treatment of major depression. This article reviews current understanding of the relationship between adult brain angiogenesis and depression.

Objective To study the effects of the monomers of ginsenoside Rb1 (GSRb1) on the concentrations of intracellular calcium in ischemic neurons of rats.Methods Hippocampus neurons from embryo of rats were cultured in vitro, then placed into normal extracellular fluid (normal control group), simulated ischemic extracellular fluid (ischemia group), simulated ischemic extracellular fluid without calcium (ischemia without calcium group) and simulated ischemic extracellular fluid with different concentration of GSRb1. The fluorescence intensity of intracellular calcium in each group was measured by laser scanning confocal microscope technique, and the corresponding percentage was calculated by comparison with normal control.Results Compared with normal control group, fluorescence intensity of intracellular calcium increased by ( 73.5?10.31)% in ischemia group, ( 4.5?2.58)% in ischemia without calcium group,( 20.2?3.41)%, ( 13.6?2.98)%,( 10.5?3.62)% and ( 12.7?4.51)%, respectively, in simulated ischemic extracellular fluid with different concentration of GSRb1 groups (20, 40, 60 and 80 ?mol/L). The decreases of fluorescence intensity of intracellular calcium in simulated ischemic extracellular fluid with different concentration of GSRb1 groups were significantly different compared with ischemia group (all P
