Objective To evaluate the value of video-assisted thoracic surgery(VATS)for penetrating thoracoabdominal injuries.Methods Under general anaesthesia and double-lumen tracheal intubation,VATS was carried out to examine patients with chest injuries.Those who had mild injuries received VATS combined with mini-incision surgery.Electrocoagulation or suturing was employed to control intraoperative bleeding,and then blood clots were removed.Injured diaphragm muscles were repaired,and organs with hemorrhage or ruptures were sutured or resected.The seriously injured cases underwent open surgery and intra-abdominal exploration instead.Results A total of 18 patients received the operations.Among them,15 patients underwent VATS combined with mini-incision surgery(repair of the diaphragm was performed on 15,controlling intercostal arterial bleeding on 8,repair of the lung on 2,wedge resection of the lung on 2,and coagulated hemothorax removal on 2),the other 3 were converted to open surgery for repairing the diaphragm(3),heart(1),or esophagus(1),or lobectomy(2).Abdominal surgery via the thorax were performed on 13 cases,including repair of the liver in 1,lienectomy in 1,gastrorrhaphy in 1,repair of diaphragmatic hernia in 3,and intra-abdominal exploration in 7.Five patients received open surgery(pancreatic neoplasty in 1,repair of the liver in 1,lienectomy in 1,gastrorrhaphy in 2,and repair of the caul and mesenterium in 3).One patient who had multi-organ penetrating injuries died of hemorrhagic shock,circulatory failure,and DIC after open thoracic and abdominal surgeries.The mean operation time in this series was(125?44)minutes(ranged from 45 to 220),and the mean blood loss was(1089?582)ml(500 to 10 000 ml).Twenty-four hours after the operation,the mean volume of chest drainage was(234?75)ml(100 to 350 ml)in the first 24 hours after the operation.The chest drainage tube was withdrawn 2.5(2 to 5)days postoperation.The patients expelled gas in 1 to 4 days(mean,2 days).Totally,12 patients were followed up for 3 to 12 months(mean,6 months),during which none of them had trauma-related complications.Conclusion VATS combined with mini-incision surgery is safe and effective for patients with thoracoabdominal injuries,if the cases were carefully selected.

Ontology alignment technology is a knowledge engineering method to realize the concept and relationship integration of different ontologies.In view of the same scope of ontology,such as disease ontology,developed by researchers from a number of different areas or institutions of independent research and development,there is a big difference between the term expression and the concept of the relationship.Thus,how to achieve the integration of multi-source ontology through alignment processing has been recognized as a significant methodological problem.In this paper,the concept,technology,method and corresponding tool of ontology alignment were expounded at full length.The technique of ontology alignment based on linguistic features and structural features was emphasized.Combined with the two international disease ontology:Disease Ontology and Orphanet,the experiment and analysis of the technique of ontology alignment were carried out and detailed the application of alignment technology.Furthermore,for the existing multi-source problems on TCM ontology database,the necessity and application of ontology alignment were discussed.

Objective The sex hormone and the corresponding receptor may play some roles in the development of the metabolic syndrome (MS) in the elderly men.This study was designed to examine the relationship of level of the sex hormone and androgen receptor with MS in elderly men,thus to investigate the possible pathogenesis of MS.Methods This cross sectional study enrolled 587 elderly men,including 400 healthy controlls aged 62-92 years and 187 MS patients aged 60-87 years in Wan Shou Lu area of Beijing city.Dehydroepiandrosterone sulfate (DHAE-S),total testosterone (TT),sex hormone binding globulin (SHBG),free testosterone (FT),follicle-stimulating hormone (FSH),Estradiol (E2),luteinizing hormone(LH) and androgen receptor (AR) in blood were tested.Statistical analyses included the comparison analysis of variables and independent variables,correlation analysis using multi-factor linear regression,and multiple logistic regression analysis.Results DHAE-S,TT,SHBG,FT and AR fluorescence intensity in healthy control group were higher than those in MS group,however,FSH and E2 levels were lower in healthy group.Age was negatively correlated with diastolic blood pressure (DBP) and FT,but positively correlated with systolic blood pressure (SBP) and E2.AR fluorescence intensity was negatively correlated with SBP and LH.The logistic regression equation showed the negative correlation between DHEA-S,SHBG and the development of MS.Conclusions There are low levels of DHEA-S,TT,SHBG,FT and AR in the elderly patients with MS.On the contrary,FSH and E2 concentration are higher.It can be suggested that low levels of DHEA-S and SHBG may be the potential risk factors of MS in elderly men.

Objective To explore the short-term and long-term efficacy of laparoscopic versus open liver resection(LLR)in the treatment of hepatocellular carcinoma(HCC). Methods The perioperative and follow-up data ofLLR(n = 43)and OLR(n = 73)for the treatment of HCC at the same period were analyzed respectively. Results There were no significant differences in the age,gender,Child-Pugh classification,liver cirrhosis, AFP,and hepatic virus affection between the 2 groups. 1 case in the LLR group was converted for the open surgery and another one case in the OLR group died in the perioperative time. However ,compared with OLR group ,the intraoperative blood loss of LLR group(P < 0.05)was larger and the mean operative time(P < 0.05)was longer. The liver function indicators of the regular hepatectomy subgroup were recovered more quickly(P<0.05),but the indicators of remaining subgroups were not significantly different. The postoperative ambulation time (P < 0.05), the postoperative eating time(P < 0.05),the postoperative hospital stay(P < 0.05)were all shorter. The VAS score was lower(P<0.05). There was no difference in the incidence and distribution of complications and the inci-dence of severe complications between the two groups(all P>0.05). The first and third year disease-free survival rates were 82.2%,53.8%for LLR and 91.5%,75.9%for OLR,respectively(χ2=0.55,P=0.46). The first and third 5 year overall survival rates were 94.2%,79.3%for LLR and 94.9%,47.3%for OLR,respectively(χ2=1.06, P=0.30). Conclusion LLR for HCC treatment is a safe and effective way with the advantages of minimal opera-tive trauma,quick recovery and significant short-term efficacy.

Objective To explore the relationship of content of plasma endothelin(ET)-1 with the change of pulmonary function in patients with chronic obstructive pulmonary disease(COPD).Method Thirty cases of the normal people were as group A ,34 cases of the patients with COPD with acute exacerbation before treatment were as group B and the patients with remission period after treatment were as group C,the plasma ET-1,arterial blood gas and pulmonary function parameters were determined from the patients before and after treatment.Results The plasma ET-1 in group B and group C were significantly higher than that in group A,the content of the plasma ET-1 had negatively correlated with PaO2,and that had positively correlated with PaCO2,P＜0.01.The pulmonary function parameters (VC,FEV1/FVC,MVV,V50 V25)in group B were significantly lower than those in group A and group C[(55.3±24.5)%,(54.8±19.3)%,(54.2±16.2)%,(54,8±9,9)%,(58.7±14.5)%;(114.8±24.1)%,(84.9±21.6)%,(86.4±17.2)%,(78.5±14.8)%,(90.3±15.4)% and (110.1±19.4)%,(85.8±15.5)%,(85.9±16.7)%,(74.5±13.4)%,(89.4±18.6)%,respectively],P＜0.01.Conclusion Pathophysiological effects of patients with COPD can be commonly adjusted by the plasma ET-1,oxygen and carbon dioxide retention,which affect pulmonary function.
