A temperature-sensitive mutant strain was isolated after transposon mutagenesis with Tn5 and named MT54.PCR was carried out with primers designed according to the sequence of transposon,the PCR products showed that the MT54 carried transposon in the genome. The mutant grew well at 30℃in minimal medium(MM)containing p-nitrophenol(PNP)as sole carbon source,while it cannot grow at 37℃in the same medium,NO_2.detection results also proved that.Comparing the degradation rate of PNP and hydroquinone of MT54 and DLL-E4 at different temperature,it was speculated that the mutant site locate in the PNP degradation related genes.

BACKGROUNDTracheal adenoid cystic carcinoma (TACC) is a rare, low malignant and primary tracheal carcinoma, which is easily misdiagnosed and missedly diagnosed. The aim of this study is to increase the knowledge about TACC.

METHODSData including clinical manifestations and treatment were retrospectively analyzed for 8 cases of TACC confirmed by pathology and follow-up was carried out.

RESULTSThe main manifestations were cough, stridor, hemoptysis and progressive inspiratory dyspnea. Fiberoptic bronchoscope and computerized tomography were reliable examinations for final diagnosis. Five cases underwent operative treatment, and three cases underwent interventional treatment by fiberoptic bronchoscope in which 1 case accepted a second operation after recurrence and 2 cases accepted chemotherapy after operation. One case was lost, 1 case treated by interventional treatment died after 11 months and other 6 cases were followed-up from 2 months to 34 months who were alive.

CONCLUSIONSTACC is low malignancy and has good prognosis. The best treatment is operation. The better palliative treatment is interventional treatment by fiberoptic bronchoscope which can relieve symptoms and improve the patient's living quality.

BACKGROUNDSarcomatoid carcinoma (SC) is a rare malignant cancer with mixed tumor and sarcomatoid tissues. The aim of this study is to investigate the clinical manifestations and pathological findings of sarcomatoid carcinoma of the lung.

METHODSData including clinical manifestations, pathological findings, treatment were retrospectively analysed from fourteen patients with lung sarcomatoid carcinoma confirmed by pathology and follow-up was carried out.

RESULTSMean age at onset was 62 years old and gender ratios (M/F) in these patients was 6:1. The clinical manifestations of lung sarcomatoid carcinoma were similar to that of other types of lung cancer while there were characteristic findings on the enhancement CT scan. Bronchofiberscopy was not a reliable examination for final diagnosis. Cells with endothelial phenotype could be detected by immunohistochemical method.

CONCLUSIONSThe final diagnosis of this disease depends on histopathological observation, while the diagnosis may be missed among patients without surgical intervention. Immunohistochemical examination is helpful for diagnosis and differential diagnosis. The therapeutic strategy is coincident with that for non-small cell lung cancer.

OBJECTIVEIt was to explore the application of the hepatitis B virus large proteins (HBV-LP) in public health physical examination through clinical testing of HBV-LP in Catering practitioners, students and soldiers of New requisition etc.

METHODS709 samples of HBV infection people were collected in public health physical examination and all collected samples were detected. ELISA was used to detect HBV serum markers (HBV-M) and HBV-LP. Real-time PCR was applied to detect quantity of HBV DNA.

RESULTS(1) The detectable results of HBV-LP and HBV DNA were no statistical significance in 709 samples. (2) The detectable results of HBV-LP and HBV DNA were also no statistical significance in different models of HBV infection patients. The values of chi2 and P were respectively 2.67, 0.60, 0.00 and 0.10, 0.44, 1.00. S/A of HBV-LP and the copies of HBV-DNA had a positive relationship (r = 0.959, P < 0.05).

CONCLUSIONHBV-LP could reflect the level of hepatitis B virus replication and be used to judge the level of hepatitis B virus replication in people of public health physical examination. HBV-LP may be worth using widely in physical examination.

OBJECTIVETo explore the character of inorganic elements in Asari Radix et Rhizoma (Xixin).

METHODThe contents of 53 inorganic elements in Xixin samples from different localities and species were determined by ICP-AES and ICP-MS. The statistical data were made using SAS.

RESULTThe result demonstrated that Xixin has the high contents of Fe, Cr, Li. It has been observed that the content of Cu and Pb of the samples are much higher than the standard level. The results of hierarchical cluster analysis revealed two groups which correspond with the species of the samples. No correlations between the contents of the inorganic elements and the localities of the samples were found. Some characteristic elements were displayed in some specific areas. The difference of the contents of the 53 inorganic elements between root and rhizome of Xixin was reported for the first time. The primary form of inorganic elements in Xixin has been studied for the first time. The result demonstrated that the extraction rate between different elements varied, with the average extraction rate of (22.25 +/- 24.96)%.

CONCLUSIONThe inorganic elements analysis of Xixin can provide evidence of its identification, cultivation and application.

BACKGROUNDThe efficacy of chemotherapy alone is still unsatisfactory in the treatment of advanced non-small cell lung cancer (NSCLC). Some kinds of solid tumors have showed good responses to chemotherapy combined with hyperthermia. This study is to investigate the feasibility and the response of hyperthermia combined with chemotherapy for advanced NSCLC.

METHODSA total of 51 patients with advanced NSCLC were eligible, in which 22 were in group HC, and the other 29 in group C. Patients in the two groups received NP (vinorelbine+cisplatin) or GP (gemcitabine+cisplatin) regimen for 2 cycles. In addition, patients in group HC received local hyperthermia twice a week, up to 12 times.

RESULTSThe response rate in group HC was 22.7%, and 13.8% in group C (P > 0.05). The clinical benefit rate in group HC was significantly higher than that in group C (P < 0.05). There was no difference in change of KPS score after treatment between the two groups.

CONCLUSIONSHyperthermia combined with chemotherapy shows good tolerance and response in patients with advanced NSCLC. Further study should be carried out.

MicroRNAs have been identified as a new class of regulatory molecules that affect many biological functions by interferring the target gene expressions. Latest studies demonstrate that microRNAs can influence many pivotal bio-processes and deeply involve in the metabolism of glucose, lipid and amino acid and biological oxidation. For glucose metabolism, microRNAs are related to insulin secretion, insulin sensitivity, glucose uptake, glycolysis, oxidation and mitochondrial function. For lipid matebolism, microRNAs can regulate the target genes related to lipid biosynthesis, catabolism and transportation. MicroRNAs can influence glutamine catabolism.

The aim of this study was to investigate the effect of haploidentical allogeneic bone marrow or peripheral blood hematopoietic stem cell transplantation (allo-HSCT) combined with umbilical cord blood mesenchymal stem cell (MSC) infusion in treatment of severe aplastic anemia (SAA). Five SAA patients received haploidentical allo-HSCT combined MSC infusion. HSC and MSC were collected from bone marrow or peripheral blood of haploidentical donors and umbilical cord blood respectively. After transplantation, the clinical hematopoietic reconstitution and early complications were monitored. The results indicated that all the 5 patients achieved hematopoietic reconstitution. The average time for WBC count > 2×10(9)/L was 13.8 days, and average time for Plt level > 20×10(9)/L was 17.8 days. The STR-PCR detection of patient peripheral blood at day 30 after transplantation showed that engraftment was complete donor's gene type. The communication with 1 patient was broken off because of his epilepsy, other 4 patients are all alive in diseases-free state. In conclusion, the haploidentical allo-HSCT combined with umbilical cord MSC infusion is an effective approach to cure SAA, which needs to be further studied in a large number of cases.
