Objectives: To analyze the strategies of the diagnosis and treatment in patients with the pulmonary infection after renal transplantation. Methods: A retrospective analysis was made on 28 cases of pulmonary infections among 285 patients undergoing renal transplantation. Results: The morbidity of pulmonary infection was 9.82%(28/285). The majority pathogens of pulmonary infection in this study were pseudomonas, staphylococcus epidermidis, canadida and cytomegalovirus. Chest X ray was important in the diagnosis, but there was no specificity to determine the pathogens. The mortality in 28 pulmonary infection patients was 32.1%(9/28). Most of the patients suffered from pulmonary infection within 4 months after the operation, and the postoperative period from 2 months to 4 months was a high risk time window for death caused by pulmonary infections. Conclusions: The morbidity and mortality of pulmonary infections, especially severe pneumonia, in patients with renal transplantation, are higher than healthy people. Treatment following clinical epidemiology and strategy of microbiology play a very important role to reduce the mortality in those patients.

OBJECTIVETo compare the effect of transurethral resection of the prostate combined with endocrine therapy (TURP + ET) with that of αlA-blockers combined with ET ((αlA-b + ET) in the treatment of bladder outlet obstruction (BOO) in patients with advanced prostate cancer (PCa), and to investigate the safety of the TURP + ET for the treatment of PCa with BOO.
METHODSWe retrospectively analyzed 63 cases of PCa with BOO, 28 treated by αlA-b + ET and the other 35 by TURP + ET. We obtained the residual urine volume (RV), maximum urinary flow rate (Qmax), International Prostate Symptom Score (IPSS), and quality of life score (QoL) before and after treatment along with the overall survival rate of the patients, followed by comparison of the parameters between the two methods.
RESULTSAt 3 months after treatment, RV, IPSS, and QoL in the TURP + ET group were significantly decreased from (137.8 ± 27.6) ml, (22.3 ± 3.6), and (4.2 ± 0.8) to (29 ± 13.6) ml, (7.8 ± 2.1), and (1.6 ± 0.5) respectively (P < 0.05), while Qmax increased from (5.6 ± 2.1) ml/s to (17.6 ± 2.7) ml/s (P < 0.05); the former three parameters in the αlA-b + ET group decreased from (133.6 ± 24.9) ml, (21.5 ± 3.2), and (4.7 ± 1.1) to (42 ± 18.3) ml, (12.8 ± 2.6), and (2.5 ± 0.7) respectively (P < 0.05), while the latter one increased from (6.3 ± 2.4) ml/s to (11.7 ± 2.3) ml/s (P < 0.05), all with statistically significant differences between the two groups (P < 0.05). The overall survival rate of the TURP + ET group was not significantly different from that of the αlA-b + ET group (51.4% vs 46.4% , P > 0.05).
CONCLUSIONTURP + ET is preferable to αlA-b + ET for its advantage of relieving BOO symptoms in advanced PCa without affecting the overall survival rate of the patients.

PURPOSE: Cockroaches are the second leading allergen in Taiwan. Sensitization to Per a 2, the major American cockroach allergen, correlates with clinical severity among patients with airway allergy, but there is limited information on IgE epitopes and tissue localization of Per a 2. This study aimed to identify Per a 2 linear IgE-binding epitopes and its distribution in the body of a cockroach. METHODS: The cDNA of Per a 2 was used as a template and combined with oligonucleotide primers specific to the target areas with appropriate restriction enzyme sites. Eleven overlapping fragments of Per a 2 covering the whole allergen molecule, except 20 residues of signal peptide, were generated by PCR. Mature Per a 2 and overlapping deletion mutants were affinity-purified and assayed for IgE reactivity by immunoblotting. Three synthetic peptides comprising the B cell epitopes were evaluated by direct binding ELISA. Rabbit anti-Per a 2 antibody was used for immunohistochemistry. RESULTS: Human linear IgE-binding epitopes of Per a 2 were located at the amino acid sequences 57-86, 200-211, and 299-309. There was positive IgE binding to 10 tested Per a 2-allergic sera in 3 synthetic peptides, but none in the controls. Immunostaining revealed that Per a 2 was localized partly in the mouth and midgut of the cockroach, with the most intense staining observed in the hindgut, suggesting that the Per a 2 allergen might be excreted through the feces. CONCLUSIONS: Information on the IgE-binding epitope of Per a 2 may be used for designing more specific diagnostic and therapeutic approaches to cockroach allergy.

OBJECTIVETo propose a method for predicting the postoperative anterior chamber depth value (ACD) based on the evaluation standard of contrast sensitivity function (CSF).
METHODSIn a personalized eye model, the natural lens was replaced with an artificial lens, and the tracing method based on ZEMAX software was utilized to simulate the pseudophakic optical system. The best MTF curve was obtained through optical optimization to calculate the CSF and determine the best contrast sensitivity (CS) curve. The best ACD value was acquired according to the CSF curve. The data form 10 cataract cases without retinal diseases were obtained and the postoperative ACD value was predicted using Holladay, Hoffer Q, SRK/T and the proposed method.
RESULTSConsistency analysis of the results showed that all the ACD values predicated by the 4 methods fell in 95% consistency within the boundaries, and the differences in the largest absolute value between the 3 methods (Holladay, Hoffer Q, and SRK/T) and the proposed method were 0.73 mm, 0.65 mm, and 0.68 mm, and the calculation results of the mean value were 5.846 mm, 5.804 mm, and 5.825 mm. Clinically, the two methods were deemed to have good consistency.
CONCLUSIONThe proposed method establishes a connection between the contrast sensitivity curve and ACD to allow better refraction adjustment for the patients.

OBJECTIVETo screen and determine the regions of copy number variation (CNV) associated with hepatocellular carcinoma (HCC) using SNP array and fluorescence quantitative PCR.
METHODSThe CNV from HCC cell line TJ3ZX-01 was analyzed using GeneChip Human Mapping 500K SNP array. According to the data obtained by SNP array analysis, four candidate amplification regions were verified in 41 primary HCC samples by fluorescence quantitative PCR.
RESULTSFour regions of copy number amplification at 1q21.2, 1q22 approximately 23.1, 7p22.1 and 22q13.1 were detected by SNP array analysis. The four candidate amplicons occurred in 56.1% (23/41) of HCC samples at 1q21.2; 80.5% (33/41) at 1q22 approximately 23.1; 75.6% (31/41) at 7p22.1 and 31.7% (13/41) at 22q13.1 analyzed with sequence tagged site (STS) markers by quantitative PCR.
CONCLUSIONIn four candidate amplification regions selected by SNP array analysis and detected by fluorescence quantitative PCR, three amplification regions show increased copy number in more than 50.0% HCC tissues. This result indicates that these amplification regions are associated with pathogenesis of hepatocellular carcinoma.

OBJECTIVETo evaluate the clinical outcome of surgical venous thrombectomy and simultaneous stenting in patients with acute, symptomatic iliofemoral deep venous thrombosis (DVT).
METHODSFrom October 2008 to December 2010, a total of 15 patients with acute symptomatic DVT underwent combined surgical venous thrombectomy and endovascular stenting in ipsilateral iliac vein. There were 6 male and 9 female patients, with a mean age of 57.4 years (ranging from 36 to 71 years). All patients underwent Duplex ultrasonography for diagnosis of DVT. The location of thrombosis was femoro-ilio-caval vein in 2 cases, bilateral iliac vein in 1 case and left iliofemoral vein in 12 cases. All patients had leg swelling and 12 cases had severe leg pain. The mean time of symptomatic DVT occurring at operation was 3.3 d. The factors related to DVT were operation in 6 cases, DVT reoccur in 2 cases. Coexist diseases were digestive tract bleeding in 1 case, gastric ulcer in 1 case, hypertension in 3 cases and 1 case had cerebral infarction. The inferior vena cava filter was inserted before thrombectomy, iliac vein compression and residual stenosis were treated with a self-expandable stent after thrombectomy.
RESULTSIntraoperative venography showed severe venous stenosis in all patients including 80% of iliac vein compression syndrome, 18 self-expandable stents were inserted successfully, the procedural successful rate was 100%, the 30-day mortality rate was 0.One case was suffered from hematoma at incision after operation. 3 patients were lost during follow-up. Median follow-up was 10.3 months (ranging from 2 to 26 months). There was no case of re-thrombosis. Leg pain was disappeared in all cases and only 2 patients showed slight leg swelling after excise.
CONCLUSIONCombined surgical thrombectomy and endovascular treatment for patients with acute symptomatic iliofemoral venous thrombosis is an effective and safe technique with low morbidity and good clinical results.
