BACKGROUND:Posterior hip dislocation combined with femoral head fractures easily induced femoral head necrosis, ectopic ossification, osteoarthritis and deep vein thrombosis. Different therapeutic methods should be utilized according to the type of fracture.
OBJECTIVE:To investigate the factors affecting the therapeutic effects and complications fol owing surgery of posterior hip dislocation combined with femoral head fractures.
METHODS:Twenty-eight patients, who had been diagnosed as posterior hip dislocation combined with femoral head fractures in the 101 Hospital of Chinese PLA from September 2004 to May 2010, were enrol ed in this study. According to Pipkin typing, operative approach and the time from injury to surgery, therapeutic effects were evaluated using radiographs and the recovery conditions of hip function (Epstein method), and the occurrence of complications was recorded.
RESULTS AND CONCLUSION:A total of 28 patients were fol owed up from 1 to 5 years, averagely 2.8 years. Using the Epstein method, there were excellent in 6 cases, good in 12 cases, average in 7 cases, and poor in 3 cases, with an excellent and good rate of 64%. The therapeutic effects in patients with Pipkin I and II were good, with excellent and good rates of 100%and 78%, respectively. Moreover, the complications were less, with a rate of 17%and 22%, respectively. The therapeutic effects of patients with Pipkin III and IV were poor, especial y, Pipkin IV patients, whose excellent and good rate was only 20%and the incidence of complications was 80%. No significant difference in the incidence of complications was detected in patients undergoing Smith-Peterson anterior approach and K-L posterior approach (P>0.05). No significant difference in the incidence of complications was detectable among patients from three groups (the time from fracture to operation<12 hours, 12-48 hours, and>48 hours) (P>0.05). Results indicated that the choice of treatment method should be determined by the type of fracture. The prognosis depends on the patient’s age, time of treatment, types of fracture and dislocation, methods of treatment and related measures of prevention of complications.

Objective To explore the autobiographical memory characteristics of chronic pain patients and its correlators.Methods Autobiographical memory,pain and emotion of 106 chronic pain patients and 106healthy controls were assessed with the Autobiographical Memory Test (AMT), the Short-form McGill Pain Questionnaire (SF-MPQ), the Pain Self-efficacy Questionaire (PSEQ), Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI).Results Compared to the control group, the clinical group had less specific memory (3.63 ± 1.53, 2.63 ± 1.68, F (1.416) = 7.233, P ＜ 0.01 ) and more overgeneral memory (2.37 ± 1.53,3.37 ±1.68, F (1.416) =7.069, P＜0.01 ),but the latency to response was not statistically significantly different between the groups.Duration of pain,frequence of pain and pain self-efficacy were the significant predictors of overgeneral memory,and the regression coefficients were significant (P＜0.05 ) ,the multiple regression equation was statistically significant( R = 0.427, R2 = 0.183, F= 2.385, P＜ 0.05 ).Conclusion The autobiographical memory of chronic pain patients was overgeneralized because of the influence of duration, frequence and self-efficacy of pain.

Objective To explore the pathogenesis of thrombocytopenia in chronic type B hepatitis. Methods The serum thrombopoietin (TPO) levels, bone marrow megakaryocyte (MK) count, platelet-associated immunoglobulin G (PAIgG), splenic index (SPI), prothrombin activity (PTA) were measured in 76 chronic type B hepatitis patients with thrombocytopenia. Results The regression analysis revealed that the platelet count was correlated with parameters including the serum TPO levels, bone MK count, SPI and PTA (r was 0.450, 0.521, -0.438, 0.428 respectively, P<0.05). The regression equation was Pt=36.38+0.23 TPO-0.57 SPI+0.69 MK, R<'2>=0.57, F=18.78, P<0.01. Conclusion It suggests that decline of thrombopoiedn, myelosuppression and hypersplenism may contribute to thrombocytopenia in chronic type B hepatitis patients.

ObjectiveTo assess negative risk factors associate with short-term and long-term poor outcome of acute heart failure syndromes(AHFS) and provide evidence to emergently proceed to AHFS low risk stratification.Methods A retrospective cohort study was conducted. 125 AHFS patients who met research criterion were enrolled from Guangxi Baise People's Hospital and Youjiang District People's Hospital of Baise City. The patients were divided into poor outcome and relatively low-risk groups by the results of short- and long-term follow-up of their outcomes. The patient's vital signs and disease history were collected at the first time after admission, and auxillary examination parameters were recorded. The poor outcomes occurring in the follow-up periods from the admission to after discharge for 30 days(short-term) and 1 year(long-term)were recorded, and Cox hazard regression was used to analyze the negative risk factor in the short- and long-term.Results There were 58 cases(46.4%)with poor outcome and 30 cases(24.0%)dead in short-term, and there were 111 cases(88.8%) with poor outcome and 39 cases(31.2%) dead in the long-term follow up. Seven negative risk factors were identified by Cox regression. They were no previous or de novo myocardial infarction〔short-term: hazard ratio(HR)=0.36, 95% confidence interval (95%CI)=0.20-0.65,P=0.001〕, lymphocyte ratio 0.20-0.40(short-term:HR=0.13, 95%CI=0.04-0.47, P=0.002; long-term:HR=0.42, 95%CI=0.26-0.68,P=0.001),oxygenation index(PaO2/FiO2)>300 mmHg (1 mmHg=0.133 kPa,short-term:HR=0.23, 95%CI=0.09-0.54,P=0.001),estimated glomerular filtration rate (eGFR)>60 mL·min-1·1.73 m-2(short-term:HR=0.31, 95%CI=0.16-0.64,P=0.002;long-term:HR=0.54, 95%CI=0.36-0.83,P=0.004),left ventricular ejection fraction(LVEF)>0.50(short-term:HR=0.29, 95%CI= 0.10-0.85,P=0.024), P wave terminal force in lead V1(PtfV1)>-0.04 mm·s(short-term:HR=0.29, 95%CI= 0.14-0.60,P=0.001), planar QRS-T angle<90°(long-term:HR=0.46, 95%CI=0.27-0.77,P=0.003). ConclusionsOur patients with AHFS cohort have very poor outcomes both in short-term and long-term follow up. Those with the following characteristics: no previous or de novo myocardial fraction, lymphocyte ratio 0.20-0.40, PaO2/FiO2>300 mmHg, eGFR>60 mL·min-1·1.73 m-2, PtfV1>-0.04 mm·s, LVEF>0.50 and planar QRS-T angle<90°are more likely to have optimal short-term and long-term outcome.

[ Objective ] To investigate the mechanism of Zhenchan Ning (ZN) for Parkinson's Disease ( PD). [Methods] Rat models of PD were established by striatal infusion of 6-hydroxy dopamine (6-OHDA) . Effect of ZN on rat rotating behavior was observed, and the contents of dopamine ( DA), homovanillic acid (HVA), superoxide dismutase (SOD), malondialdehyde (MDA), glutathione (GSH) and glutathione peroxidase (GSH-PX) in blood and corpus striatum were also detected. [Results] As compared with those before treatment, high-dose ZN could improve the rotating behavior and decrease the rotating frequency ( P 0.05), but could decrease serum MDA content (P

Objective To evaluate the role of the beta3 subunit of the voltage-gated sodium channel (Scn3b) in neuropathic pain in mice.Methods The target gene Scn3b was embedded in the vector pBROAD-mcs and pBROAD3-mcs-Scn3b plasmid was then obtained.The primary mice were bred.The primary mice mated with C57/B6 mice and the transgenic mice were then generated.DNA,RT-PCR and Western blot experiments were performed to confirm the mice in which Scn3b was over-expressed.The mice with Scn3b over-expression multiplied rapidly to carry out the follow-up experiment.Ten transgenic mice (Scn3b group) and 10 control mice in the same litter (Con group) of both sexes,aged 2 months,weighing 25-30 g,were randomly chosen to establish the model of neuropathic pain.The mechanical pain threshold was measured before operation and on 3,5,7 and 14 days after operation.Results There was no significant difference in the mechanical pain threshold at each time point between the two groups (P ＞ 0.05).Conclusion Scn3b is not involved in the development and maintenance of neuropathic pain in mice.

Objective To investigate the risk factors for postoperative liver failure of patients with hepatocellular carcinoma (HCC) and bile duct tumor thrombus through a risk evaluation model.Methods The clinical data of 107 patients with HCC and bile duct tumor thrombus who received hepatic resection at the Eastern Hepatobiliary Surgery Hospital from March 2002 to February 2011 were retrospectively analyzed.All patients were divided into the non-liver failure group (98 patients) and liver failure group (9 patients).Risk factors associated with liver failure were analyzed and a risk evaluation model was established.All data were analyzed using the bivariate regression model,and factors with significance were further analyzed using the multivariate regression model.Results Of the 107 patients,105 received hepatic resection + choledochotomy + thrombectomy and 2 received hepatic resection + extrahepatic bile duct resection + cholangiojejunostomy.The operation time was 2.0-5.5 hours,and the intraoperative blood loss was 200-3500 ml.In the non-liver failure group,5 patients had pleural and peritoneal effusion,3 had biliary bleeding,2 had incisional infection,1 had biliary infection,1 had bile leakage,1 had stress-induced ulcer of upper digestive tract and 1 had thoracic epidural hematoma.The bleeding of the patients with thoracic epidural hematoma was stopped after thoracic spinal decompression,but subsequent paraplegia occurred.In the liver failure group,2 patients died of postoperative acute liver failure,and 7 patients died of postoperative subacute liver failure (death caused by tumor recurrence or medicine was excluded).The results of univariate analysis showed that preoperative total bilirubin,albumin,pre-albumin,albumin/globulin ratio,distribution of tumor thrombus,operative blood loss and ratio of postoperative residual liver volume to the total liver volume were correlated with the postoperative liver failure in patients with HCC and bile duct tumor thrombus (OR =3.017,0.191,0.248,2.681,9.048,4.759,13.714,P ＜ 0.05).The results of multivariate analysis showed that preoperative total bilirubin ＞ 256.5 μmol/L,albumin/globulin ratio ≤ 1.3 and postoperative residual liver volume ＜ 50％ were the independent risk factors of postoperative liver failure (OR =5.537,11.107,172.450,P ＜ 0.05).The risk evaluation model was Z =1.77 × preoperative total bilirubin + 2.408 × preoperative albumin/globulin ratio + 5.150 × ratio of postoperative residual liver volume to the total liver volume-17.288.The risk of postoperative liver failure increased as the increase of Z value.The risk of postoperative liver failure ＞ 50％ when the Z value ＞ 0.Conclusions Preoperative total bilirubin ＞ 256.5μmol/L,albumin/globulin ratio ≤ 1.3 and postoperative residual liver volume ＜ 50％ were the independent risk factors of postoperative liver failure.Risk evaluation model is helpful in screening the risk factors so as to decrease the incidence of postoperative liver failure.

Objective To summarize the experiences of a single treatment group in surgical treatment of hilar cholangiocarcinoma during the past 10 years. Methods From January 2000 to December 2009, 1572 patients with hilar cholangiocarcinoma were admitted to the Eastern Hepatobiliary Surgery Hospital, and the clini-cal data of 462 patients in our treatment group were retrospectively analyzed. Among the patients, 314 received surgical treatment, and the remaining 148 received conservative interventions or refused any therapy. Factors that may have influenced the prognosis were analyzed by the Kaplan-Meier method, Log-rank test and Cox proportional hazards model. The correlation of different factors was analyzed by the chi-square test. Results A total of 314 patients underwent surgical treatment and tumor resection was performed in 237 patients, including 174 with R0 resection, 17 with R1 resection, and 46 with R2 resection. There were 91 patients with postoperative complications and 10 in-hospital deaths. A total of 260 patients had been followed up for 5-113 months, and the overall 1-, 3-, and 5-year survival rates were 71.7% , 32.6% and 10.9% , respectively; the 1-, 3-, and 5-year survival rates of patients with R0 resection were 76. 9% , 48. 6% and 32. 7% , respectively, with a median survival time of 35 months. R0 resection, TNM staging, regional lymph node involvement and tumor differentiation were the independent prognostic factors (RR = 2. 1, 1.9,2.2, 1.7, P<0.05). Conclusions Curative resection is the treatment of choice for hilar cholangiocarcinoma. Preoperative systematic evaluation and preparation can improve the radical resection rate and reduce postoperative morbidity.
