Objective: To evaluate therapeutic effect of aortic endovascular stent-graft exclusion (EVGE) combined percutaneous coronary intervention (PCI) on patients with descending thoracic aortic dissection (DTAD) complicated coronary heart disease (CHD).Methods: A total of 58 DTAD + CHD patients undergoing aortic EVGE combined PCI were regarded as EVGE group (received aortic EVGE at first, then PCI on 3d after operation).Another 60 DTAD+CHD patients undergoing open surgery combined PCI in our hospital were selected as open surgery group.Both groups were observed and followed up, and their therapeutic effects were compared.Results: Compared with open surgery group, there was significant rise in complete cut closure rate (78.33% vs.91.38%), and significant reductions in bleeding volume during operation [(919.83±242.12) ml vs.(58.17±9.53) ml], postoperative infection rate (15.0% vs.3.4%) and hospital stay [(16.40±0.96)d vs.(9.10±0.83)d] in EVGE group, P<0.05 or <0.01.Success rate of PCI was 100% in EVGE group, and there was no PCI-related severe complications.During follow-up, coronary restenosis rate within 12 months in EVGE group was significantly lower than that of open surgery group (5.20% vs.15.30%, P=0.04).Conclusion:It is safe and possesses significant effective to treat descending thoracic aortic dissection complicated coronary heart disease using aortic endovascular stent-graft exclusion combined percutaneous coronary intervention, which is worth extending.

BACKGROUND:Calcaneal fractures with subtalar arthritis were treated with bone graft fusion in the clinic, but previous big “L” approach could cause great trauma to patients, and was not conducive to the patient’s recovery. OBJECTIVE:To explore the repair effect of modified smal “L” approach in bone fusion Kirschner wire on calcaneal fractures with subtalar arthritis. METHODS: Clinical data of 23 patients with calcaneal fracture with subtalar arthritis in the First Hospital-Fengtai Hospital, Peking University from November 2012 to November 2013 were retrospectively analyzed. Al patients received modified bone graft fusionvia smal “L” approach. Repair effect was observed. American Orthopaedic Foot and Ankle Society scores and hind foot scores were evaluated before and after treatment. RESULTS AND CONCLUSION:Bone graft fusion was successfuly conducted in 23 patients. The operation time was 55-90 minutes, averagely (70±2.5) minutes. Al incision was healed wel after operation. Wound infection or flap necrosis did not occur. During folow-up, patients reached bone healing, and no talus osteonecrosis or bone absorption appeared. By the time of the last folow-up, AOFAS score of 23 patients was (85.6±3.7), which was significantly higher than (50.3±6.2) points before treatment (P < 0.05). These results suggest that modified bone graft fusion with smal “L” approach for calcaneal fracture with subtalar arthritis obtained good clinical effects.Moreover, the operation was simple and the complications were less. This method can effectively solve the insufficient exposure of inside of the subtalar joint via previous approaches and big processing difficulty.

Objective To investigate the significance of early blood lactic acid and lactic acid clearance in patients with post-cardiac arrest syndrome(PCAS).Methods 87 cases were divided into the survival group(26 cases) and the death group(61 cases).The clinical data of two groups were analyzed statistically.Results The 6h blood lactate (8.46 ± 2.37) mmoL/L,6h blood lactate clearance rate (34.53 ± 14.75) ％,the residual alkali (-3.08 ± 3.68) mmol/L,6h SevO2 (68.35 ± 6.33) ％,APACHE Ⅲ score (19.64 ± 2.48) points in the survival group were significantly better than those of the death group [blood lactic acid value (12.32 ± 3.56) mmol/L,6h blood lactate clearance rate (27.71 ± 11.38) ％,the residual alkali (-5.61 ± 4.14) mmol/L,6h SevO2 (63.22 ± 5.94) ％,APACHE Ⅲ score (24.32 ± 5.33) points],with significant differences between two groups (t =5.99,2.36,2.73,3.66,5.62,all P ＜ 0.05).The 6h blood lactate clearance rate,6h SevO2 and APACHE Ⅲ score were independent risk factors for the prognosis of PCAS (OR =1.23,1.64,1.28,all P ＜ 0.05).Conclusion The early blood lactate clearance rate can be used as a sensitive indicator for evaluating the prognosis of PCAS.

Radiotherapy and interventional thearapy are the main means for unresectable advanced primary hepatic carcinoma.However,the efficacies are restricted by their respective adaptability.The development of radiotherapy,especially the application of radiotherapy combined with transcatheter hepatic artery chemoembolization provide more suitable treatment means for patients.

Objective To investigate the feasibility of unilateral neck exploration for parathyroid adenoma. Methods The clinical data of preoperative image localization and intraoperative unilateral neck exploration of 15 cases of parathyroid adenoma from 1996 to 2002 in our hospital were analyzed retrospectively. Results Unilateral neck explorations of the 15 cases were performed successfully with the guidance of preoperative ultrasonography , CT, MRI and 99m Tc MIBI scans, and the treatment effect was satisfactory. Conclusion Unilateral neck exploration of parathyroid adenoma could be feasible if accurate preoperative image localizations are available.

Objective To investigate the relationship between serum surfactant protein-A (SP-A) and -D (SP-D) in patients with systemic lupus erythematosus (SLE) complicated with interstitial lung disease.(SLE-ILD) and its clinical significance.Methods Serum SP-A and SP-D levels of SLE patients and controis were assessed using a sensitive enzyme-linked immunosorbent assay (ELISA).The relationship between SP-A and SP-D and SLE-ILD,the correlation between SP-A and SP-D with age,disease activity index,pulmonary function test and high-resolution computed tomography (HRCT) score were analyzed.Results The level of serum SP-A and SP-D in patients with SLE is higher than that in healthy controls(P＜0.05).The level of serum SP-A and SP-D in patients with SLE complicated with ILD was higher than that in patients without ILD and healthy controls (P＜0.05).The level of serum SP-D in patients with SLE-ILD was correlated positively with HRCT score (r=0.508,P=0.004) and interstitial score (r=0.468,P=0.009),and it correlated inversely with vital capacity (%VC) (r=-0.590,P=0.001 ) and diffusing capacity of carbon monoxide (%DLCO)(r=-0.588,P=0.001 ).There was no correlation between the level of serum SP-A with SLE-ILD and HRCT score,%VC and %DLCO.The level of serum SP-D in patients with SLE-ILD correlated positively with serum IgG (r=0.376,P=0.040),and the level of serum SP-A in patients with SLE-ILD correlated positively with serum C reactive protein (CRP)(r=0.403,P=0.027).There was a positive correlation between the level of serum SP-D in patients with SLE and age (r=0.352,P=O.001 ).Conclusion The levels of serum SP-A and SP-D may be useful markers for ILD in patients with SLE.There is correlation between the level of serum SPD and HRCT score,pulmonary function test,and it is positively correlated with age and disease activity index.

Epidemiological studies have shown that the incidence of patent foramen ovale (PFO) in patients with cryptogenic stroke is significantly higher than general population.The close association between cryptogenic stroke and PFO supports the hypothesis that paradoxical embolism is a cause of stroke.However,the detection of PFO alone does not establish the diagnosis of paradoxical embolism in patients with cryptogenic stroke. The risk of ischemic stroke will increase significantly when PFO and other factors coexist.Some studies tave shown that there is significant difference between the MRI lesion patterns in patients with cryptogenic stroke and PFO in those without cryptogenic stroke,particularly in multiple ischemic lesions.Therefore,it does not support the theory of paradoxical embolism as a cause of stroke in patients with PFO.The PFO detection methods include transthoracic echocardiography,transesophageal echocardiography (TEE) and transcranial Doppler (TCD).TCD and TEE have a good consistency.Accordingly,TCD should be recommended as a simple,noninvasive,and reliable technique,while TEE should be only restricted to the selected patients.The treatment options of PFO include antiplatelet drugs,anticoagulant drugs,percutaneous vascular closure,and thoracotomy.Percutaneous vascular closure should only be considered the recurrent events during the medical treatment,the contraindications of medical treatment,and PFO with some anatomical high risks for patients with cryptogenic stroke with PFO before the completion of several large randomized controlled trials.

Thymic stromal lymphopoietin (TSLP) is an epithelial cell-derived cytokine. TSLP exerts a profound influence on the polarization of dendritic cells and T helper2 cytokine production. TSLP also directly promotes T-cell proliferation in response to T-cell receptor activation and Th2 cytokine production. TSLP affects different populations of cells,indicative of the broad role of TSLP in the regulation of respiratory tract infected and inflammatory processes.

Objective To analyze the pregnancy outcomes and measures to prevention and cure for pregnancy women with pulmonary hypertension.Methods Clinical data of 40 women with pulmonary hypertension were analyzed and they were divided into three groups on the basis of Doppler transthoracic echocardiography detections.Results(1)The proportions of rheumatic heart disease and congenital heart disease were 22.64% and 45.38%;8 cases appeared with the perinatal heart disease and 5 cases' hearts structure were normal.(2)49 cases applied cesarean section and 2 delivery naturally.2 women were induction of labour in second trimester.In midrange and severity groups,prematurity and small gestational age were significently higher than those of gentle group.(3)3 women died of congestive heart failure and pulmonary embolism.6 women were treated by SICU and physician because of serious illness.Conclusion Women with midrange and severely pulmonary hypertension should avoid pregnancy.Pregnant women with pulmonary hypertension needed monitor closely and being treated with pulmonary vasodilator added decoagulant would improve outcomes of mather and infant.

Objectives To verify if chemotherapy drug gemcitabine could induce a change of protein expression in pancreatic cancer cell line SW-1990, and to provide evidence for clinical therapy. Methods We use two-dimensional gel eleclrophoresis(2-DE), mass speclrornetry and bio-information methods to compare the change of protein expression before and after gemcitabine and 5-FU treatment of cell line SW-1990, and identify the discrepant protein expression. Results The concentration of gemcitabine, that can suppress 50 percent of the pancreatic cancer cells was 1-100 ng/ml, while same suppression for 5-FU was 250-2500 ng/ml. Six discrepant protein expressions, one in 5-FU group and 5 in gemcitabine group were found. Conclusions Gemcitabine has better therapeutic effects on the growth of pancreatic cancer cell line SW-1990 than that of 5-FU. Gemcilabine was involved in sugar and fat metabolism, and it could induce some changes of protein expression, for example ?-actin and MGC: 19713, which is of somewhat importance for clinical investigation of pancreatic cancer therapy.
