A strain of thermotolerant halophilic bacteria YJ0238 was isolated from the salt well at 47℃ in the Kangning countryside where was located at the side of Lancang River in the Tibet Autonomous Region. Some physiological and biochemical properties were characterized.16S rRNA gene sequence of YJ0238 was amplified by PCR,and its nucleotide sequence was determined. Based on it’s physiological and biochemical properties,homology and phylogenetic analysis of 16S rRNA gene sequence,strain YJ0238 was identified as a subspecies of the species Idiomarina zobellii. The GenBank accession number of the 16S rRNA gene sequence of strain YJ0238 is EF693953. Until now,there were few reports on the study of high-temperature and high-salt microbial in domestics. The results of this study will provide research material and information for further studies in this area.

Objective To judge method performance of routine biochemistry parameters on Roche Modular PPI testing system by using westgard's method evaluation decision chart.Methods We assessed imprecision(CV)from internal quality control and inaccuracy(bias)from external quality control evaluation.Combined estimates of imprecision and inaccuracy by plotting imprecision as the x-coordinate and inaccuracy as the y-coordinate to locate an expected operating point of every item on the chart.By comparing this operating point with allowable total errors(TEa),we can decide whether the performance is acceptable or not.Results In the 27 different parameters tested,imprecision and bias of calcium were 0.08 mmol/L and 0.06 mmol/L respectively,its performance was marginal.The imprecision of creatinine,urea,glucose, sodium,chloride and phosphorus were 3.20%,2.13%,1.52%,0.89 mmol/L,1.10% and 1.55%,the bias were 4.79%,0.96%,4.63%,0.80 mmol/L,1.74% and 4.13% respectively,their performance was good.M1 other 20 items were of excellence performance.Conclusions Routine biochemistry parameters on Roche Modular PPI testing system possessed good precision and accuracy,and their performance were acceptable.To judge method performance of biochemistry testing system by using westgard' s method evaluation decision chart was easy to do and suited for clinical laboratory.

Objective:A retrospective study was conducted to evaluate the efficiency of postoperative radiotherapy for completely resected, pathologically Stage Ⅲ a (N2) non-small cell lung cancer (NSCLC). Methods:From January 1989 to December 1993, among the patients with NSCLC who underwent radical surgery in the authors’hospital, there were 119 patients with completely resected, pathologically Stage Ⅲ a(N2)NSCLC. A total of 55 cases of these patients received postoperative radiotherapy with dose of 46-62 gray in mediastinum and hilus (S+ RT group), except other 64 cases (S group). The survival rates and local control rates were analyzed and compared by the life table and Log-rank. Results:The clinical characters of patients such as age, sex, pathologic type were similar between two groups. The 1,3,5-year survival rates were 80.0% , 32.7% , 25.5% respectively in S+ RT group and 76.4% , 36.4% , 23.0% respectively in S group, with no significant difference between two groups( P >0.05) . The median time of local recurrence was 21 months in S+ RT group and 12 months in S group, with significant difference between two groups(P<0.05) . The 1,3,5-year local control rates were 94.0% , 78.5% , 69.0% respectively in S+ RT group in contrast to 83.1% , 58.3% , 50.6% respectively in S group(P< 0.05). The metastasis rates were similar in two groups ( P>0.05) . Conclusion:Postoperative radiotherapy can increase the local control rates and prolong the time of local recurrence for the patients with completely resected, pathologically Stage Ⅲ a (N2) NSCLC, but the survival rate can not be improved.

OBJECTIVETo observe the effect of SHENG MAI ZHUSHEYE on the movement parameters and viability of human sperm in vitro.
METHODSWe collected sperm samples from 33 normal fertile men, divided each into two, and cultured them in vitro with SHENG MAI ZHUSHEYE + Hams-F10 and Hams-F10 alone, respectively. Then we measured the straight line velocity (VSL), curvilinear velocity (VCL), average path velocity (VAP) and the amplitude of lateral head displacement (ALH) of the sperm by computer-aided semen analysis at 0.5, 1, 2, 4, 8 and 12 h. And the sperm viability was detected.
RESULTSVCL was significantly higher at 8 h (P < 0.05) and very significantly higher at 12 h (P < 0.01) in the SHENG MAI ZHUSHEYE + Hams-F10 group than in the Hams-F10 group. VSL, VAP and ALH were significantly increased in the former group at 4, 8 and 12 h as compared with the latter (P < 0.05). The sperm viability was significantly decreased in the Hams-F10 group at 12 h (P < 0.05).
CONCLUSIONSHENG MAI ZHUSHEYE can improve sperm movement parameters and increase sperm viability in vitro.

Objective To evaluate the control effect of the policy sustainable elimination of iodine deficiency disorders on the disease status after 15 years salt iodization, and to provide a scientific basis for the relevant policy adjustments. Methods Probability sampling method (PPS) was used to select 30 counties in Jiangsu province(except those iodine excess areas), of each county 40 children aged 8 - 10 were selected as the investigation objects, their thyroids were examined by palpation and B ultrasound, urinary iodine(UI), household salt iodine, and intelligence quotient(IQ) were also investigated. A questionnaire-based health education survey of children and women was also conducted. Results A total of 1200 salt samples were detected and the coverage and qualified rates of iodized salt were 97.5%(1170/1200) and 94.5%(1134/1200), respectively. Five hundred and ninety eight urinary samples of children aged 8 to 10 were detected. The median urinary iodine was 325.3 μg/L. Of 1200 children aged 8 to 10 examined, goiter was 1.70% (20/1200) by palpation and 1.00% (12/1200) by B ultrasound. Average IQ of those 598 children was 112.4 ± 13.2, and the proportion of mental retardation was 0.5% (3/598). The health education awareness were 95.9%(1830/1908) and 96.4%(431/447) for 636 students and 149 family women, respectively. Conclusions The control effect of iodine deficiency disorders is significant in Jiangsu province. Salt iodine concentration should be adapted to people's iodine nutritional status. Iodine nutrition needs of special population such as pregnant, lactation women and infants should be taking into account, and should also be combined with salt iodization status surveillance at county level.
