Objective To discuss clinical efficacy of the modified Stoppa approach in the treatment of acetabular anterior fractures.Methods From January 2011 to December 2014,22 patients with acetabular anterior fracture were treated at our department.They were 14 males and 8 females,with an average age of 36.6 years (range,from 18 to 49 years).By the LetourneI-Judet classification system,there were 9 anterior wall fractures,12 anterior column fractures,and one transverse fracture.The modified Stoppa approach was used for fracture reduction under direct visualization in this cohort.Fixation with reconstruction plate was conducted after satisfactory reduction was confirmed by the X-ray examination.The operative duration,incision length,bleeding volume,fracture reduction quality,function of the affected hip and complications were recorded.Results In this cohort,the incision length ranged from 6 to 15 cm,averaging 9.5 cm;the intraoperative bleeding volume ranged from 100 to 1,000 mL,averaging 550 mL;the operative duration ranged from 40 to 160 minutes,averaging 126.2 min.The 22 patients were followed up for an average of 15.5 months (from 12 to 18 months).According to the Matta imaging evaluation,the fracture reduction was rated as excellent in 18 cases,as good in 3 cases and as poor in one,yielding an excellent to good rate of 95.5％.According to the Harris scoring system,the function of the affected hip was assessed at the final follow-up as excellent in 12 cases,as good in 9 cases,and as poor in one case,giving an excellent to good rate of 95.5％.Traumatic arthritis occurred in one case;there were no such complications as reduction loss or implant failure.Conclusion The modified Stoppa approach is a satisfactory one for the treatment of unstable acetabular anterior fractures,owning to its advantages like minimal invasiveness,simple dissection,excellent visual control of reduction and fixation,and a low rate of complications.

OBJECTIVE:To clarify the bio-transformation form of apigenin in rats,and to speculate its possible metabolic path-way. METHODS:Rats were divided into blank group and medication group(apigenin 200 mg/kg,i.g.)with 6 rats in each group. Urine and feces samples were collected from 2 groups within 24 h after medication. After corresponding treatment,urine and feces samples were analyzed and detected by HPLC-IT-TOF-MSn under cation mode and anion mode. RESULTS:9 metabolites were iden-tified in urine sample of rats from medication group,i.e. 2,3-double bond reduction of apigenin (U1,U7,U8,U9),bonded to glucuronic acid(U2,U3,U4),bonded to sulphate(U5,U6,U7,U8,U9)and bonded to glucose(U2). 4 metabolites were iden-tified in feces sample of rats from medication group,i.e. 2,3-double bond reduction of apigenin(F3),bonded to glucuronic acid (F2)and bonded to glucose(F1). CONCLUSIONS:Apigenin mainly exists in form of prototype drug in rats. The reduction hap-pens on 2,3-double bond by the intestinal bacteria,and the product of apigenin boned to glucuronic acid or glucose can be formed when excreting in intestinal tract and rats in vivo,while the product of apigenin boned to sulphate can be formed only when excret-ing in rats in vivo.

According to the design of medical specialist system and the features of Cancer Prevention and Treatment in China, suggestions of Oncologic specialist training were proposed as following. Applying the training by phases is suitable, the conceptions, principles and protocols for Comprehensive treatment and standardized treatment are core contents for the Oncologic specialist training process, which should be carried out in tumor hospital prior to general hospital, the special therapy for the special disease is the aim of Oncolngic specialist training.

Objective To investigate the merit and feasibility of vasoactive drugs by the double atrial infusion in children with congenital heart disease combined with pulmonary hypertension.Methods Ninety cases of congenital heart disease combined with pulmonary hypertension were randomly selected.One group(45 cases) was infused by double atrialadministration,which left atrium for catecholamines,and right atrial infusion for highly targeted expansion of pulmonary vascular drugs,such as prostaglandin E1.Another group(45 cases) was infused through the right atrium by a central venous to catecholamines and pulmonary vascular dilatation drugs.Cardiac output(CO) and cardiac index were measured by thermal dilution method and systemic vascular resistance and pulmonary vascular resistance(PVR) were calculated.Results Three cases were dead in early postoperative period(1 week),which were central intravenous group.2 cases with total anomalous pulmonary venous drainage had low co after operation,include 1 case through the left atrium,and the other case through central venous administration,and were recovered.There was no long-term mortality.There was no significant difference in CPB time,blocking time,the amount and timing of vasoactive drugs in two groups (P ＞ 0.05).Conclusion Double atrial infusion of vasoactive drugs can significantly reduce the mean pulmonary artery pressure and pulmonary vascular resistance,and increase CO,which is better than the traditional central intravenous methods.The treatment method is of very important significance.Thus double atrial infusion is safe and feasible.

We mainly introduce the design of teaching objectives,teaching content,teaching strategies and teaching effect evaluation for the elective course of SPSS and statistical data processing and summarize and reflect on the implementation after teaching combined with the practical teaching of medical statistics.

Objective To investigate protective effects of thrombopoietin ( TPO) on cerebral model control in rats and associated signal transduction pathway. Methods Thread embolism was performed to generate cerebral ischemia-reperfusion rat model. Eighty male SD rats were randomly divided into sham operation group, model control group, TPO group, TPO and Janus kinase 2 ( JAK2 ) kinase inhibitor ( AG490 ) group. Before 30 min of ischemia-reperfusion, TPO group was given TPO (5 μg·kg-1) by intraperitoneal injection, TPO + AG490 group was given TPO (5 μg·kg-1) before 30 min of ischemia reperfusion, then given AG490 (8 μg·kg-1), and model control group were given the same dose of 0. 9% sodium chloride solution. The observation time points were 6, 12, 24, and 48 h after ischemia reperfusion. Immunohistochemical staining and Western blotting were used to measure the protein levels of Bcl-2, JAK2 and signal transducer & activator of transcription (STAT3). TdT-mediated dUTP nick end labeling (TUNEL) was used to detect apoptosis. Results Compared with model control group, the number of apoptotic cells were significantly reduced [(67. 50±9. 37) vs. (40. 20±7. 47)], the expression levels of Bcl-2, JAK2 and STAT3 protein were significantly increased [(35. 40±7. 39) vs. (78. 70±9. 75);(35. 68±6. 75) vs. (62.35±7.53); (25.40±9.45) vs.(55.36±9.69), respectively] 24 h after ischeia reperfusion in the TPO group (all P<0. 05). Compared with the TPO group, the Bcl-2, JAK2 and STAT3 protein levels were significantly decreased in TPO and AG490 group [(78. 70±9. 75) vs. (55. 40±9. 35);(62. 35±7. 53) vs. (40. 68±5. 89); (55. 36±9. 69) vs. (30. 40±9. 39), respetively], and the number of apoptotic cells was significantly increased [(40. 20±7. 47) vs. (55. 23±7. 65)] (all P<0. 05). Conclusion TPO can inhibit cell apoptosis after ischemia-reperfusion injury, the mechanism might be related to the activation of JAK2/STAT3 signal transduction pathway through raising the expression of Bcl-2 gene.
