Manual immunohistochemistry for detecting ALK gene fusion antibody in 519 cases of non-small lung cancer / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the expression of anaplastic lymphoma kinase (ALK) gene fusion antibody in non-small cell lung cancer (NSCLC) and explore the clinicopathological significance.</p><p><b>METHODS</b>Using 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).</p><p><b>RESULTS</b>The 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.</p><p><b>CONCLUSION</b>Manual IHC can be reliable for screening ALK fusion arrangement in patients with NSCLC.</p>

Prevention of osteopenia and dyslipidemia in rats after ovariectomy with combined aspirin and low-dose diethylstilbestrol / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>To study whether effect of aspirin plus low-dose diethylstilbestrol is more effective and safer than high diethylstilbestrol dose alone on prevention of ovariectomy-induced osteopenia and dyslipidemia.</p><p><b>METHODS</b>Thirty-eight 4-month-old female SD rats were divided into baseline (BAS) group (n=6), sham operation group (n=8) and ovariectomy (OVX) group (n=24). The OVX group was further divided into vehicle treatment group (n=8), diethylstilbestrol (30 μg/kg•d) treatment group (OVX+D30 group, n=8), and aspirin (9 mg/kg•d) plus diethylstilbestrol (10 μg/kg•d) treatment group (OVX+A-D10 group, n=8). Their left tibiae were collected for the bone histomorphometric analysis in undecalcified sections. Left femurs were collected for the bone mineral density measurement.</p><p><b>RESULTS</b>The body weight and serum cholesterol were increased, while uterine weight and cancellous bone mass were decreased in OVX rats compared with the SHAM group. Cancellous bone mass was significantly increased, while body weight and bone resorption parameters were decreased in both A-D10 and D30 treatment group compared with OVX group. The rats treated with A-D10 showed significantly increased in bone formation parameters and decreased in serum triglyceride compared with the D30-treated rats.</p><p><b>CONCLUSION</b>Aspirin plus low-dose diethylstilbestrol can effectively prevent osteopenia by reducing bone resorption, and is thus a better treatment modality for preventing dyslipidemia than high-dose diethylstilbestrol alone.</p>

Effects of different mechanical ventilation methods on morphology of type Ⅱ alveolar epithelium cell in newborn piglets with acute lung injury / 中华实用儿科临床杂志

Objective To investigate the effects of 3 different ventilation methods,including conventional mechanical ventilation(CMV),high-frequency oscillatory ventilation(HFOV) and partial liquid ventilation(PLV),on the morphology of type Ⅱ alveolar epithelium cell (ACE Ⅱ) of newborn piglet with acute lung injury (ALI).Methods Twenty-four less than 3-day-old newborn piglets were enrolled.After ALI was established with saline lavage (38 ℃,0.035 L/kg),newborn piglets were randomly assigned to 4 study groups:control group(n =6,no ventilation),CMV group(n =6),HFOV group(n =6),and PLV group(n =6,38 ℃,0.018 L/kg).Piglets in the 4 groups were sacrificed after being ventilated for 24 hours,and the number,area,density of fluorescence of ACE Ⅱ were detected.Results Through 24 hours mechanical ventilation,the numbers of ACE Ⅱ in CMV group,HFOV group and PLV group remained were 30 ± 5,52 ± 5,81 ± 7,respectively,while areas of fluorescence were 340.40 ± 47.50,329.69 ± 124.50,295.55 ± 109.30,respectively,and there were significant differences among the 3 groups,and the population mean of density of fluorescence had significant difference among the 3 groups.The number of ACE Ⅱ remains was lowest in CMV group compared with HFOV group(P =0.026) and PLV group (P =0.000),and the density of fluorescence of ACE Ⅱ was lowest in CMV group compared with HFOV group (P =0.001) and PLV group (P =0.002).Conclusions Different mechanical ventilations have various effects for ACE Ⅱ,and CMV is the most harmful mechanical ventilation on ACE Ⅱ,while PLV is the least harmful.

Cone beam computed tomography for vascular interventional radiology procedures: early experience

<p><b>INTRODUCTION</b>Cone beam computed tomography (CBCT) is a relatively new technological innovation that utilises fl at-panel detector technology to obtain CT-like images. The key strength of a CBCT system is that cross-sectional imaging can be obtained using the angiographic fl at panel unit without having to move the patient, allowing the radiologist to obtain soft tissue imaging during the procedure. This allows treatment planning, guidance, and assessment of outcome to be performed in one interventional suite.</p><p><b>MATERIALS AND METHODS</b>From December 2008 to June 2009, 24 CBCT scans were performed during vascular interventional procedures on our department's newly installed multi-axis fl at panel angiographic unit.</p><p><b>RESULTS</b>Ten cases were performed for hepatic trans-arterial chemoembolisation, 9 cases for hepatic arterial Yttrium-90 infusion, while 5 cases were for other indications. CBCT was found to be useful in 20 of the 24 cases.</p><p><b>CONCLUSION</b>Our early experience showed that CBCT was useful in impacting decisions during selected vascular interventional procedures. As CBCT technology improves, we can foresee wider applications of this technology.</p>

Genetic analysis of the nonstructural gene (NS1) of H9N2 avian influenza viruses isolated in China / 病毒学报

The nonstructural genes (NS1) of nine H9N2 subtype avian influenza viruses isolated from diseased chickens on different farms during 1998-2005 were amplified by RT-PCR and completely sequenced. The nucleotide and deduced amino acid sequences of NS1 genes of these isolates were compared. The results showed that NS1 genes of all H9N2 isolates contained 654 bp and encoded 217 amino acids. The homologies of the nucleotide and deduced amino sequences of the isolates were 95.4%-99.8% and 93.6%-100%, respectively. Comparison of the amino acid sequences of NS1 proteins of these isolates with other H9N2 viruses demonstrated that NS1 proteins of the nine strains had a deletion of 13 amino acid residues at the carboxyl terminus, which may be the molecule mark of the isolates in mainland China. Phylogenetic analysis revealed that the NS1 genes of these isolates fell into the same lineage and belonged to allele A. Eight out of nine isolates belonged to the CK/SH/F/98-like lineage while only Ck/HN/A3/98 strain belonged to the Ck/HK/Y280/97-like linease. All the isolates were derived from Ck/BJ/1/94 strain which was the first isolate is mainland China in 1994. The results indicated that H9N2 subtype AIV appeared differentiation following the passage of time and the viruses belonging to Ck/SH/F/98-like acquired an epidemic spread advantage in chicken population in mainland China.

Phylogenetic analysis of enterovirus 71 isolated from patients with hand, foot and mouth disease in Guangdong and Fujian provinces, 2000-2001 / 中华实验和临床病毒学杂志

<p><b>OBJECTIVE</b>To identify enterovirus 71 (EV71) strains isolated from patients with hand, foot and mouth disease (HFMD) in Guangdong and Fujian provinces from 2000 to 2001 by using phylogenetic analysis.</p><p><b>METHODS</b>All 25 samples were first tested for enteric viruses by RT-PCR using enterovirus specific primers EV-1 and EV-2, and then were identified for EV71 by RT-PCR using EV71 specific primers 159S and 162A. The amplicons of 485bp segment (part of the VP1 gene) were cloned into pGEM-T and sequenced. A phylogenetic tree was constructed by comparison of the sequences with other 12 EV71 strains isolated from China, Japan, Hungary, and the United States including the prototype BrCr.</p><p><b>RESULTS</b>The positive rate of EV71 was about 20%. The sequence analysis showed that the new isolate (GZH2000) shared 94%-96% nucleotide identity with three strains isolated in 1998 and 2000, and 91% with a strain isolated in 1987 from Chinese mainland, but shared only 82%-84% homology with EV71 isolates studied abroad.</p><p><b>CONCLUSIONS</b>EV71 is one of the important pathogens of HFMD in south China. The strains isolated from mainland were closely related with most isolates from Taiwan, but different from most EV71 strains reported abroad. The symptoms of EV71 infection in mainland were not as intensive as those described in Taiwan's outbreak.</p>
