Objective To compare the effects of rib internal fixation and thoracic external fixation in treatment of traumatic flail chest. Methods Eighty six cases of traumatic flail chest with multiple injuries,admitted to hospital from January 2006 to June 2009 ,were recruited into the study and divided into rib internal fixation and thoracic external fixation groups randomly. The clinical data were analyzed retrospectively. Rib internal fixations with Ti-Ni shape memory alloy embracing connector were performed in internal-fixation group(n = 45) and thoracic external fixations were performed in external-fixation group(n = 41). The outcomes were compared between the two groups. Results No patient in internal-fixation group developed chest wall deformity,while 19 patients in external-fixation group had chest wall deformity left. The mean times of hospital stay([ 15. 1 ± 1.8]d vs [22. 9 ±2. 8]d,t = - 15. 724,P ＜0. 01) ,ICU stay([5.7 ± 1.5]d vs [ 14. 4 ±2. 9]d,t =- 17.711, P ＜ 0. 01), and mechanical ventilation([ 3.9 ± 1.5 ] d vs [ 1 1.6 ± 2. 3 ] d, t = - 17. 256, P ＜ 0. 01),in internal-fixation group were significantly shorter than those in external-fixation group. The occurrence rate of respiratory complications (including pulmonary inflammation and (or) atelectasis and (or) respiratory failure)in internal-fixation group was significantly lower than those in external-fixation group(35.6% vs. 70. 7% ,x2 =10.641,P ＜ 0.01). Followed-up data of three months after discharge showed that the pulmonary function parameters, such as total lung capacity([ 89. 5 ± 3. 1 ] % vs. [ 79. 1 ± 5. 1 ] %, t = 11. 705, P ＜ 0. 01), forced vital capacity([ 80. 2 ± 2. 8 ] % vs. [ 69. 8 ± 3. 8 ] % ,t = 14. 241 ,P ＜0. 01) ,forced expiratory volume in the 1st second ([74.8 ±4.4]% vs. [71.9 ±3.6]% ,t =3.201,P ＜0.01),peak expiratory flow ([82.8 ±4.4]%vs. [79. 8 ±4. 9]% ,t =2. 885,P ＜0. 01) and forced expiratory flows at 75% of the vital capacity( [68.2 ±2. 2] % vs. [61.9 ± 2. 9 ]%, t = 11. 286; P ＜ 0. 01) were significantly higher in internal-fixation group than those in external-fixation group. Conclusion Rib internal fixation for traumatic flail chest can quickly correct chest wall deformity, stabilize thoracis and eliminate paradoxical chest wall movement. Patients accepted this treatment have a shorter therapy process during the intensive care unit and hospital stay, less pulmonary complications. They also show less long-term restrictive pulmonary functions impairment, when compared to the patients in the thoracic external fixation group. Rib internal fixation with Ti-Ni shape memory alloy embracing connector is a simple and effective therapy.

AIM:To investigate the histone modification changes of topoisomerase Ⅱα( TOPOⅡα) promoter regulatory factor Sp1 in the patients with chronic benzene poisoning .METHODS:The bone marrow samples were collect-ed from 25 chronic benzene poisoning cases and 25 controls.The chromatin immunoprecipitation assay was carried out to study the possible mechanism of TOPOⅡαpromoter regulatory factor Sp 1 expression changes .The mRNA expression of Sp1 was detected by RT-PCR.RESULTS:Compared with the controls , the histone H4 acetylation and histone H3 acetyla-tion of Sp1 in the chronic benzene poisoning patients significantly decreased (P<0.01), and histone H3K9 methylation level of Sp1 increased (P<0.01), but the histone H3K4 methylation level of SP1 was not obviously changed (P>0.05). The mRNA expression of Sp1 in the chronic benzene poisoning patients was significantly lower than that in the controls (P<0.05).CONCLUSION:In chronic benzene poisoning patients , the histone acetylation and methylation modification changes of TOPOⅡαpromoter regulatory factor Sp 1 accompanied with the changes of mRNA level are observed .Histone H4 and H3 acetylation and H3K9 methylation modification of Sp1 may play an important role in the benzene ’s hematopoiet-ic toxicities.

Iatrogenic traumatic biliary stricture is one of the difficult points in the biliary surgery,and operation is the only definitive treatment. The operative opportunity,surgical procedure and techniques are important for the prognosis.From January 1998 to December 2011,173 patients with iatrogenic traumatic stricture were admitted to the Eastern Hepatobiliary Surgery Hospital. According to the Bismuth classification of traumatic biliary stricture,10 patients were in type Ⅰ,22 in type Ⅱ,87 in type Ⅲ,38 in type Ⅳ and 16 in type Ⅴ.Excision of the traumatic stricture with end-to-end anastomosis was performed on 19 patients.Of the 173 patients,154 were treated by Roux-en-Y duodenojejunostomy, and 8 of them received additional hemihepatectomy or partial hepatectomy.A total of 155patients were followed up,with a median time of 74 months,the total excellent and good rate was 94.8％ ( 147/155 ).Surgery is the most effective therapy for iatrogenic traumatic biliary stricture. Optimal timing, reasonable surgical methods, strictly following the principle of biliary surgery and perfect operative skills are key points for a better prognosis.

Objective To evaluate the effects of simvastatin on the vascular elasticitv in fat-fed rabbits by echo-tracking(ET)technique.Methods Twenty seven rabbits were divided randomly into 3 groups:normal control group(group A),high fat diet group(group B),simvastatin group(group C:high fat diet for the 1st 4 weeks and high fat diet+simvastatin for the 2nd 4 weeks).β,EP,AC,and PWVβof abdominal aorta (AO) and femoral artery(FA)of rabbits in group A、B、C were measured by ET technique at the end of 4th week and 8th week respectively.The expression of iNOS was measured at the end of 8th week.Results At the end of the 4th week,β,Ep,and PWVβ of FA were significantly inereased and AC was significantly decreased in group B compared to those in group A(P＜0.05).At the end of the 8th week,β,Ep,PWVβof AO were significantly increased and AC was significantly decreased in group B compared to those in group A(P＜0.05);β,Ep,PWVβ of FA were statistically decreased and AC was statistically increased in group C compared to those in group B(P＜0.05),however there was no significant difference of AO between groups B and C.Conclusions Short-term administration of simvastatin can improve the elasticity of some muscular arteries such as FA but not AO.

Objective To establish a proper extraction method for Yangxue Ruanjian Prescription (YRP) by comparing the chemical component contents and analgesic and anti - inflammatory effect of extracts extracted from YRP by different methods. Methods Water - decocting, alcohol - refluxing and alcohol - percolating methods were adopted and component indexes of paeoniflorin and gentiopicrin were determined by HPLC. The anti - inflammatory effect of the extracts were observed on mice with xylol - induced auricular swelling and analgesic effect by hot - plate method. Results The content of gentiopicrin is similar in the extracts extracted by three methods and the content of paeoniflorin is higher in alcohol - percolating extract than in alcohol - refluxing extract, lowest in water - extraction. The analgesic effect of water - decocting extract is better than that of alcohol - refluxing extract, and that of alcohol - percolating extract is weakest; the anti - inflammatory effect of the three extracts is almost the same. Conclusion Water - decocting extraction is suitable to YRP, and this is determined by the characteristics of Chinese compound prescription.

Objective To investigate the effects of electroacupuncture (EA) on the implementation of blind nasojejunal (NJ) tube placement and enteral nutrition (EN) in neurosurgical severe coma patients in intensive care unit (ICU).Methods Seventy-nine neurosurgical severe coma patients admitted to ICU were randomly divided into conventional group (blind NJ tube placement,n =40) and EA group (NJ placement and EA,n =39).EA was performed after NJ tube placement at bilateral acupoints Zusanli (ST36) and Hegu (L14) points using EA treatment instrument.The impelling distance of NJ tube were measured and the success rate of NJ tube placement were calculated.The postoperative complications were observed.Results The difference of NJ tube impelling distances at the 24th,48th,and 72th hours after surgery in EA group were significant longer than that in conventional group (P ＜ 0.05).The success rates of NJ tube placement at the 24th and 72nd hours after surgery in EA group were significantly better than that in conventional group (P ＜ 0.05).Their EN calories qualifiedness rate in 72 hours also increased significantly compared with conventional group and the proportion of patients assisted with parenteral nutrition decreased (P ＜0.05).The postoperative complications including alimentary tract hemorrhage,vomiting,and abdominal distension decreased remarkably in EA group compared with conventional group (P ＜ 0.05).Conclusions EA stimulation at acupoints could promote the gastrointestinal peristalsis of neurosurgical severe coma patients and elevate the success rate of blind NJ tube placement,so it is beneficial for the implementation of early enteral nutrition (EEN).
