Objective To study the point mutation of FUT2 gene in Chinese Han population.Methods Using direct sequencing,molecular cloning techniques and the comparing with the gene sequence reportedby Kelly, the FUT2 gene structures of 41Chinese Han individuals have were studied.Results The G428A mutations of FUT2 gene was not found,but the A385T and C357T mutations were found in the 41 Chinese Han individuals.Among the 41 individuals,24 had A385T mutation and 17 had no A385T mutation.The neutral mutation C357T was found in all 41individuals.Conclusion The G428A point mutation of FUT2 which is commonly found in non secretor of Africans and Caucasian was not found in Chinese population.There are A385T and C357T point mutations which were found in 41 Chinese Han individuals.The present stady shows the difference between Chinese and Caucasian,and other non secretor mutations will be revealed by further investigation

Objective To study the Secretor gene (FUT2) molecular structure of Uighur population in Xinjiang area,China. Methods DNA was extracted from 40 Uygur unrelated donors' blood and sequence analysis of FUT2 genes was performed. Results Four mutations in the FUT2 genes of Uighur donors have been identified. The frequencies of mutations were 71.25% for 357T, 28.75% for 357C,77.50% for 385A,22.50% for 385T,70% for 428G,30% for 428A,72.50% for 739G and 27.50% for 739A. Conclusion Based on the characteristics of FUT2 gene structure of Xinjiang Uighur,it cauld be thought that there are some relationships between Xinjiang Uighur, Taiwanese of China and Caucasiany.

Of the 250 cases of blunt abdominal trauma,15 cases of pancreatic lesions were complicatedwhich include 3 cases lacerated on the head of pan-creas, 5 on the body, 6 on the tail and one con-tused. The pancreatic bed drainage was performedfor one case, repair for 8 cases and pancreatic tailresection for 6 cases, In author's experiences, theroutinely inspecting the pancreas was carried outintra operatively, with blunt epigastric trauma, es-pecially the light red hemotoliquid was found bypericentesis. Operative method was classified frompancreatic bed drainage, repair and resection in ac-cordance with severity of the trauma, For prevent-ing the pancreatic juice fistula, the main pancreaticduct must try its best to be ligated. If the traumais on the head, a common bile duct and duodenumdecompression must be done.

Myelodysplastic syndromes ( MDS ) represent a heterogeneous group of clonal hematopoietic disorders with diverse clinical course .Because of the heterogeneity and the lack of molecular markers to monitor disease progression, clinical management of MDS patients is challenging .Recently, with the development of molecular analysis techniques , an increasing number of MDS related molecular biomarkers have been reported.In this review, we will discuss the clinical applications of the newly reported molecular makers in terms of diagnosis , prognosis and treatment.These markers may improve the diagnosis and prognostic assessment systems of MDS , which may potentially be used to guide decision making in the individual therapy.

The mutation status of calreticulin gene (CALR) is helpful for the diagnosis of JAK2 / MPL mutation-negative myeloproliferative neoplasms (MPN), and is closely related to the MPN progression and prognosis.Currently, Sanger sequencing, PCR-fragment analysis, high resolution melting, Taqman RQPCRand the next generation sequencing have been reported to be used to detecting the CALR gene mutations.A proper method for CALR mutation detection and a right laboratory diagnostic procedure according to the MPN-related molecular markers will facilitate the rapid and effective diagnosis and treatment of MPN.

Objective To find antitumor cOnstituents from Tripterygium hypoglaucum.Methods The chloroform extract of T.hypoglaucum was separated by silica gel column chromatography and preparative HPLC.The structures of compounds isolated were identified by spectral analysis and chemical evidence.Results Seven compounds were isolated and identified as rhein ethyl ester(1),chrysophenol(2),physcion(3),emodin(4),wilfordine(5),wilforgine(6),and wilforine(7).The cytotoxic activities of the compounds against cancer cell lines were assayed.Conclusion Compound 1 is a new natural compound with strong activities against human cancer cell lines (A2780 and OVCAR-3).Compounds 2-4 are isolated from this genus plants for the first time.The possible structure-activity relationship among compounds 1-4 shows that the methoxy group or oxyethyl moiety might be responsible for the cytotoxity.

Objective To elucidate the molecular basis for induced resistance of N. gonorrhoeae to ceftriaxone in vitro. Methods The reference strain ATCC49226 and clinical isolate ZSSY00205 of N. gon-orrhoeae were exposed to subinhibitory concentration of ceftriaxone for the induction of resistance. Then,suppression subtractive hybridization was performed with the pre-induction parent strains as drivers and post-induction mutant strains as testers to create a subtractive cDNA library. Following that, a total of 192 clones were randomly selected from the library, and arrayed by spotting onto nylon membranes. Finally, dif-ferentially expressed genes were screened by hybridization with labeled-RsaI restriction fragments from the sensitive and resistant N.gonorrhoeae strains respectively, and analyzed by sequencing and homology research using Blast program. Results A subtractive library for these resistant N.gonorrhoeae strains was generated by SSH technique. Microarray analysis and homology research confirmed 5 genes related to ceftriaxone resistance, i.e. mtrR, mtrC, gyrB, rpsJ and PJD1. Conclusions The induced resistance of N. gonorrhoeae to ceftriaxone may be associated with mtrR, mtrC, gyrB, rpsJ and PJD1 genes which probably mediate the resistance by enhancing the activity of efflux pump system.

Objective To evaluate the effect of occupation al protection measures on reducing blood exposure. Methods A s urvey was carried out to investigate medical staff in Shanghai hospitals. Sing le-factor and multi-fa ctor analysis measures were used. Results The more protection m eas ures adopted, such as gloves using, occupational training and strict rules and r egulations, the less occupational exposure. The resul ts also showed that there were statistical difference. Conclusions It is important for medical staff to strength occupational protection in order to avoid acqu iring hospital infection.
