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.

OBJECTIVETo explore possible alterations in velopharyngeal function after maxillary advancement.

METHODSTen patients (3 secondary deformity of cleft palate, 7 maxillary retrusion) had maxillary advancement surgery. Pre- and post-operative examinations consisted of lateral cephalometric radiography, nasopharyngoscopy and speech recording.

RESULTSThere was no significant changes on speech or velopharyngeal competence after maxillary advancement. Cleft palate patients appeared slight hypernasality and nasal emission.

CONCLUSIONSGood velopharyngeal function pre-operation is not affected after the surgery of maxillary advancement.

Background Biomaterials for corneal tissue engineering must demonstrate several critical features for potentialutility invivo, includingtransparency, mechanicalintegrity, biocompatibilityand slow biodegradation. Silk film biomaterial had been characterized to meet these functional requirements. ObjectiveThis study was to investigate the feasibility of physico-crosslink regenerated silk fibroin film as tissue engineered corneal scaffold. MethodsHuman corneal epithelial cells(CECs) links were cultured by regular method and CECs in logarithmic phase were than incubated on physico-crosslink regenerated silk fibroin film membrane. The shape of cultured human CECs was observed after 24,48 and 72 hours under the inverted microscope and scanning electron microscope( SEM ) ,and the CECs were cultured on culture plates as controls. The growth state of CECs on regenerated silk fibroin film was observed daily for 7 days by MTT, and cell cycle analysis and the presence of apoptosis of human CECs were examined by flow cytometry after incubation on regenerated silk fibroin film. Regenerated silk fibroin filmCECs (4 mm×3 mm) were implanted into the corneal stroma of the right eyes of New Zealand white rabbits. At the end of 4 and 8 weeks after implantation, the appearance of the ocular surface was examined using slit lamp and corneal neovascular area was measured. Corneal histopathological examination was carried out to assess the degradation of graft materials and immunohistochemistry was performed to detect the expression of CD34 in the corneal tissue after operation. ResultsThe morphology and structure of CECs were identical using the two cultured Methods when observed under the inverted microscope and SEM after 24,48 and 72 hours. No significant difference was found in the A490 value 1,2,3,4,5,6 or 7 days after incubation on regenerated silk membrane and in culture plates ( Fmethod =0. 641 ,P＞0.05 ). The apoptosis rates of CECs on regenerated silk membrane or culture plates were 1.8％ and 2.0％ and the amount of cells in G2/G1 phase was 1. 956 and 1. 945, respectively. Histopathological examination showed that the regenerated silk membrane material degraded and was replaced by regular collagen tissue 2 months after implantation,and the presence of neovascular area and inflammatory cells were less prominent in 2 months than 1 month post-implantation. The expression level of CD34 in corneal tissue was evidently lower 1 and 2 months after operation than the Ad-VEGF165-induced positive control group (P＜0. 05), and no significant differences were seen when compared with normal CECs(P＞0.05). ConclusionsPhysico- crosslink regenerated silk fibroin film is an excellent biomaterial for tissue engineered corneal scaffold with good biocompatibility.
