An extremely thermoacidophilic isolate K4-1 was obtained from an acidic hot spring in Teng- chong Rehai, Yunnan province. Morphology, growth characteristics, utilization of carbon compounds, en- ergy sources and 16S rRNA gene sequence of K4-1 were studied. Cells of K4-1 are irregular cocci with monotrichous flagella. The strain grew aerobically in either a lithotrophic or a heterotrophic mode. Growth on elemental sulfur occurred through oxidation of sulfur. It grew optimally at 75?C and pH 3.5. On the basis of 16S rRNA gene sequence similarity, strain K4-1 was shown to belong to genus Sulfolobus, being related to the type strains of genus Sulfolobus (86.6%~94.3% similarity), and being most closely related to strain Sulfolobus tengchongensis RT8-4 (98.9% similarity). The GenBank accession number of strain K4-1 16S rRNA gene sequence is EU729124.

OBJECTIVETo recognize the clinical features of the bronchiolitis obliterans.

METHODClinical manifestation, chest X-ray, computed tomography (CT) and pulmonary function of 4 cases with bronchiolitis obliterans were retrospectively analyzed.

RESULTTwo cases were after Stevens-Johnson syndrome (SJS), the other 2 were after severe pneumonia, including one suffered from adenovirus pneumonia. Cough, tachypnea and wheezing persisted in all the 4 patients. The symptoms lasted for at least 6 weeks, in one case for over one year. Crackles and wheezing were present in all the 4 cases. Hyperinflation was seen in chest radiographs in all cases. On pulmonary CT/high-resolution CT (HRCT), patchy opacity and bronchial wall thickening were seen in each patient. Areas of air trapping were seen in three cases. Bronchiectasis was seen in 2 cases, atelectasis and mosaic perfusion were seen respectively in one case. PO(2) was low in all the four cases. Wheezing was not responsive to beta(2) agonist and other bronchodilating therapy. Prednisone was used at a dose of 1 mg/(kg.d) in 3 cases. Two cases were followed up for 3 months. The clinical condition of one case was improved, whose wheezing and bronchiolar constriction disappeared, cough and dyspnea were also relieved. However, the condition of one patient was not improved, although the wheezing disappeared. The HRCT of these two cases showed no improvement.

CONCLUSIONClinical symptoms of BO were cough, tachypnea, and wheezing after acute lung injury. Crackles and wheezing were the most common signs in the BO. Chest radiographs showed hyperinflation. Pulmonary CT showed bronchial wall thickening, bronchiectasis, atelectasis, and mosaic perfusion. Pulmonary function tests suggested obstruction of small airway.

In order to build a protein expression system in a cold-adapted bacterium Acinetobacter sp. DWC6, a promoter probe vector was constructed based on the plasmid pBR322. A fragment containing the promoter of the beta-lactamase gene (the ampicillin resistance gene) in pBR322 was eliminated and replaced by a fragment comprizing a kanamycin resistance gene amplified from pJRD215. DNA fragment harboring in the Acinetobacter species specific ori was also inserted into the plasmid pBR322 to construct a promoter probe vector named pBAP1, which could replicate both in E. coli and in Acinetobacter sp. DWC6. The promoter selection library was constructed by randomly inserting genomic DNA fragment of Acinetobacter sp. DWC6 at upstream of reported gene, and target promoters were screened from genomic library on ampicillin selection plates. The function of pBAP1 and isolated promoters were determined by detection of the ampicillin sensitivity and the expression level of beta-lactamase in the host cell.

OBJECTIVETo study expression of proto-oncogenes c-fos and its accompanying gene c-jun in osteoblasts activated by action of excessive fluoride in vivo and in vitro.

METHODSExperimental Wistar rats were exposed to sodium fluoride (NaF) added to their drinking water, and NaF was also added in cell culture supernatant for osteoblast-like cells in vitro. Expression of both mRNA and protein of c-fos and c-jun in bone-tissue of rats with chronic fluorosis and cultured osteoblast-like cells were determined by hybridization in situ, Western blot and immunohistochemistry at varied time periods after exposure.

RESULTSSodium fluoride could stimulate the proliferation of osteoblast in rats with chronic fluorosis and induce expression of both c-fos and c-jun in all envelops of the spine bone, as compared with its control group. Value of optical absorption in mRNA expression of c-fos and c-jun was 139.63 and 126.37, respectively, in rats with NaF plus high-calcium, significantly lower than that in control group with high-calcium only (107.74 and 117.48, respectively) (P < 0.001). Immunohistochemical analysis showed that protein level of c-fos and c-jun was significantly higher in rats with NaF plus high-calcium than that in control rats with high-calcium only, with values of optical absorption of 139.16, 131.15, 149.98 and 149.19 (P < 0.05), respectively, and protein level of c-fos and c-jun was significantly higher in rats with NaF plus low-calcium than that in control rats with low-calcium only, with values of optical absorption of 117.24, 111.46, 132.46 and 129.79 (P < 0.05), respectively. Western blotting showed that level of protein expression of c-fos and c-jun in periosteal osteoblasts was significantly higher in all rat groups with NaF than that in all control groups, with values of optical absorption of 123.32, 116.60, 115.97 and 108.30, respectively. mRNA expression of c-fos and c-jun in osteoblast-like cells treated with NaF for 12 h increased obviously, and remained at high level 48 h after exposure, with values of optical absorption of 114.80, 161.14, 118.20, and 150.41, respectively, as compared with that in control group (P < 0.001 and P < 0.05).

CONCLUSIONSExposure to excessive fluoride could stimulate activation and proliferation of both osteoblasts in rats and cultured osteoblast-like cells in vitro, and cause enhanced expression of mRNA and protein of both c-fos and c-jun. Over-expression of c-fos could play an important role in development and proliferation of skeletal lesions in rats with chronic fluorosis.

OBJECTIVETo determine the diagnostic value of B72.3, BerEP4 and calretinin in differentiating metastatic carcinoma cells from reactive mesothelial cells (RMC) in serous effusions by using immunocytochemical method (ICC), and to investigate the feasibility of ThinPrep (TP) preparation for ICC.

METHODSOne hundred fifty eight serous effusion specimens were examined by ICC on cell block (CB) sections (CB-ICC) using antibodies against of B72.3, BerEP4 and calretinin. Fourty-nine of the samples, ICC on ThinPrep slides (TP-ICC) and CB-ICC were performed concurrently.

RESULTSThe sensitivities of B72.3 and Ber-EP4 for detecting carcimoma cells were 76.9% and 69.2% respectively, and when combined the sensitivity was increased to 89.7%. The sensitivity and specificity of Calretinin for detecting mesothelial cells were 90.9% and 87.2% respectively. The sensitivity of B72.3 in differentiating cancer cells from reactive mesothelial cells by CB-ICC and TP-ICC was 78.9% and 68.4%. It was 78.9% and 68.4% of BerEP4 respectively. No statistical significance was observed between CB-ICC and TP-ICC in differentiating metastatic carcinoma cells from reactive mesothelial cells.

CONCLUSIONThe combination of antibodies of B72.3, Ber-EP4 and calretinin is quite helpful as an auxiliary in differentiating metastatic carcinoma cells from reactive mesothelial cells. ThinPrep preparation slides may effectively replace the cell block sections for ICC in differential diagnosis of serous effusions.
