Objective To investigate the influencing factors of hemorrhagic transformation in non-thrombolysis patients after acute cerebral infarction. Methods According to Chengdu Stroke Registry Project,2598 consecutive patients with acute cerebral infarction admitted to the Department of Neurology,West China Hospital within 1 week of attack from January 2010 to December 2013 were enrolled prospectively. The patients were divided into a hemorrhagic transformation group and a non-hemorrhagic transformation group according to whether they had hemorrhagic transformation or not. As for patients with hemorrhagic transformation,they were divided into a symptomatic hemorrhagic transformation (SHT)group and an asymptomatic hemorrhagic transformation (ASHT)group according to whether they had aggravation of symptom and sign. The baseline data of all patients were collected and compared between the groups. The P<0. 1 variables of the univariate analysis result were enrolled in multivariate logistic regression analysis in order to identify the independent influencing factor of hemorrhagic transformation. Results In 2598 patients,249 (9. 6%)had hemorrhagic transformation,28 of them (1. 1%)were SHT and 221 (8. 5%)were ASHT. There were significant differences in male,hypertension,dyslipidemia,atrial fibrillation,drinking and smoking ratio,blood glucose,cholesterol,low density lipoprotein cholesterol, National Institutes of Health Stroke Scale (NHISS)scores,and the trial of Org 1072 in acute stroke treatment (TOAST)classification between the HT group and the non-HT group (all P<0. 05). There were no significant difference in the related influencing factors between the SHT group and the ASHT group (all P>0. 05). The results of multivariate logistic regression analysis showed that dyslipidemia (OR,0. 588, 95%CI 0. 374-0. 924,P=0. 021)was negatively correlated with hemorrhagic transformation. Atrial fibrillation (OR,3. 188,95%CI 2. 159-4. 707,P<0. 001),blood glucose (OR,1. 081,95%CI 1. 044-1. 119,P<0.001),and NHISS score (OR,1. 305,95%CI 1. 170-1. 455,P<0. 001)were positively correlated with hemorrhagic transformation. In TOAST classification,relative to the large atherosclerotic stroke,the small artery occlusive cerebral infarction was negatively correlated with hemorrhagic transformation (OR,0. 315, 95%CI 0. 167-0. 596,P<0. 001). After removing the influencing factor of atrial fibrillation,compared with the large artery atherosclerotic stroke,cardioembolism stroke was positively correlated with hemorrhagic transformation (OR,2. 823,95%CI 1. 946-4. 095,P<0. 001). Conclusion Dyslipidemia,atrial fibrillation,blood glucose,NHISS score and TOAST classification were independently associated with hemorrhagic transformation in non-thrombolysis patients after acute cerebral infarction.

OBJECTIVETo evaluate the early outcome of patients who underwent video-assisted thoracic surgery (VATS) lobectomy for primary lung carcinoma.

METHODSThe records of 121 patients with lung cancer undergoing VATS lung resection from 1997 to 2004 were reviewed retrospectively, I stage: 101 cases, 34 cases underwent right upper lobectomy, 13 cases underwent right middle lobectomy, 17 cases underwent right down lobectomy, 21 cases underwent left upper lobectomy, 16 cases underwent left down lobectomy. Thirty-eight cases underwent VATS lobectomy without assisted mini-incision.

RESULTSThere were 18 cases of morbidities (15%) and no surgical mortality. The 1-year, 2-year and 3-year survival rates of primary non-small cell lung cancer with I stage is: 99% (76/77), 96% (49/51) and 79% (15/19), respectively. There are statistic difference (P < 0.01) between adenocarcinoma and the others. There are no statistic difference (P > 0.05) between the VATS lobectomy with assisted mini-incision (n = 38) and without (n = 63), also no statistic difference (P > 0.05) between the VATS lobectomy and the standard procedure.

CONCLUSIONOur findings suggest that VATS lobectomy is superior regarding its ability to achieve the same survival rates and little morbidities in comparison with the standard procedure.

OBJECTIVETo compare video-assisted thoracic surgery (VATS) and open thoracotomy (OT) on acute inflammatory responses and immunosuppression after lobectomy for early non-small cell lung cancer (NSCLC).

METHODSPresent prospective randomized study. OT or VATS lobectomy was performed in patients who met enter criteria and clinical data was collected. Plasma concentration of IL-6, IL-8 and IL-10 were measured before surgery and at postoperative day (POD) 1 and POD 3. There were 271 patients underwent lobectomy for early NSCLC, including of 133 patients in group VATS and 138 patients in group OT from January 2007 to June 2008. There were 132 males and 139 females, aging from 19 ∼ 70 years with a mean of (56 ± 8) years.

RESULTSCompared with OT group, shorter postoperative hospital stay [(8.2 ± 2.5) d vs. (9.8 ± 6.2) d, P = 0.03], lower morbidity rate (11.3% vs. 21.7%, P = 0.02) and lower increase of plasma concentration of IL-6 at POD 1 [(35 ± 25)% vs. (65 ± 43)%, P = 0.00], IL-6 at POD 3 [(14 ± 22)% vs. (55 ± 44)%, P = 0.00] and IL-10 at POD 1 [(25 ± 20)% vs. (43 ± 35)%, P = 0.00] were observed in patients of VATS group.

CONCLUSIONVATS lobectomy for early NSCLC is associated with less acute inflammatory responses and less immunosuppression when compared with OT.

BACKGROUNDTrabeculectomy has become a mainstream treatment in intraocular pressure (IOP) reduction for primary angle-closure glaucoma (PACG); combined trabeculectomy and cataract surgery was reported to reduce IOP and simultaneously improve vision for patients with PACG and coexisting cataract. This study was specialized to compare the efficacy and safety of combined phacotrabeculectomy with that of trabeculectomy only in the treatment of PACG with coexisting cataract.

METHODSThis is a comparative case series study. Thirty-one patients (31 eyes) with PACG and coexisting cataract were enrolled. Of these, 17 underwent phacotrabeculectomy and 14 underwent trabeculectomy alone. IOP, filtering blebs, and complications were compared at the final follow-up. Complete success was defined as a final IOP less than 21 mmHg without IOP-lowering medication.

RESULTSAfter 10 months of postoperative follow-up, the phacotrabeculectomy and trabeculectomy groups showed no significant differences regarding IOP reduction ((20.59 ± 7.94) vs. (24.85 ± 14.39) mmHg, P = 0.614), complete success rate (88% vs. 71%, P = 0.370), formation rate of functioning blebs (65% (11/17) vs. 93% (13/14), P = 0.094), and complications (41% (7/17) vs. 57% (8/14), P = 0.380). IOP-lowering medication was not required for most of the patients in both groups. Additional surgery interventions, including anterior chamber reformation and phacoemulsification, were needed in the trabeculectomy group, whereas no surgery was needed postoperatively in the phacotrabeculectomy group.

CONCLUSIONPhacotrabeculectomy and trabeculectomy treatments exhibit similar IOP reduction, successful rates, and complications when it comes to treating PACG patients with coexisting cataract, although additional surgery intervention may be needed for a few cases with cataract and complications after trabeculectomy.

OBJECTIVETo investigate the expression of anaplastic lymphoma kinase (ALK) gene fusion antibody in non-small cell lung cancer (NSCLC) and explore the clinicopathological significance.

METHODSUsing manual immunohistochemistry (IHC) with D5F3 rabbit monoclonal antibody, we detected the expression of ALK gene fusion protein in 519 cases of NSCLC. The relations of ALK fusion protein with the clinical characteristics of the patients and the histological classification of the tumors were analyzed. The expressions of ALK fusion protein were compared between surgical specimens and biopsy samples, and the consistency of manual IHC results was evaluated with the results of a fully automated IHC instrument and fluorescence in situ hybridization (FISH).

RESULTSThe positivity rate of ALK fusion protein was 11.37% (59/519) among the cases detected by manual IHC. The patients tended to have a young age of onset (P=0.048) and most of the tumors were adenocarcinoma. In the surgical specimens, ALK fusion protein was expressed mostly in invasive mucinous adenocarcinoma (P<0.01), and it was a high risk factor of lymph node metastasis [OR=2.188(95%C.I:1.161-4.122)]. No statistical difference was found in the test results of manual IHC between surgical specimens and biopsy samples. The results by manual IHC suggesting a strong expression were consistent with the results by automated IHC and FISH.

CONCLUSIONManual IHC can be reliable for screening ALK fusion arrangement in patients with NSCLC.
