Based on studying the manifestation of untranslatability of traditional Chinese medicine (TCM) technical terms, and through analysis on the enriched cultural content and special linguistic characteristics, the author summarized the factors that caused the untranslatability, and suggested some projects for compensation and reformation, including transliteration, word-formation, free translation and literal translation. Although the existence of untranslatability of TCM technical terms is affirmable, on account of the uninterrupted international cultural communications, the untranslatability of TCM terms will not be lasting invariable.

Objective To construct the Neisseria surface protein A (NspA) DNA vaccine of Neisseria gonorrhoeae and evaluate the humoral and cellular immune responses induced by this vaccine in mice model.Methods The recombinant expression vector pcDNA3.1 (+)/NspA was constructed by inserting NspA gene into the eukaryotic expression vector pcDNA3.1 (+) and confirmed by poly merase chain reaction (PCR),restriction enzymes HindⅢ,XbaⅠand DNA sequencing.NspA mR- NA in transfected RAW264.7 cells and NspA protein expression in transfected COS-7 cells were de- tected by reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemical stai- ning,respectively.Forty-five male BALB/c mice were immunized with pcDNA3.1 (+)/NspA recom binant plasmid.The level of serum anti-Neisseria gonorrhoeae antibody of the immunized mice was detected by tube agglutination test,and the level of interieron (IFN)-?was assayed by enzyme-linked immunosorbent assay (ELISA).The proliferation of splenocytes was determined by methyl thiazolyl tetrazolium (MTT) colormetry.The NspA gene in BALB/c mice was identified by PCR with the total DNA extracted from quadriceps femoris in immunized sites.Results Restriction enzymes digestion a- nalysis and DNA sequencing results revealed that the pcDNA3.1 (+)/NspA had been constructed successfully.NspA gene had been transcripted and expressed in mammalian cells.The peak titer of specific antibody was 1:640 in pcDNA3.1(+)/NspA immunized group and there was no specific an- tibody detected in both pcDNA3.1 (+) immunized group and PBS group.The IFN-?level in pcD NA3.1 (+) immunized group was (23.79?11.85)pg/mL and that in pcDNA3.1 (+)/NspA immu- nized group was(169.71?30.52)pg/mL (P

OBJECTIVETo study molecular epidemiology of norovirus (NV) infections, stool specimens collected from children with acute diarrhea were tested by TaqMan real-time reverse transcription polymerase chain reaction (RT-PCR) for the viral specific nucleic acid segments.

METHODSFecal samples from a total of 1260 children who had watery diarrhea seen from December 2006 to December 2007 in Guangzhou were analyzed by real-time RT-PCR. The primers and probes used for rapid detection and typing of NV strain target NV sequences were at the ORF1-ORF2 junction, a highly conserved region of the NoV genome. The positive specimens were determined by nested PCR and sequenced.

RESULTSTotally 257 specimens were positive for NV with a positive rate of 20.40%. Shedding of NV type GI was detected in 6.90%, type GII in 16.98% respectively, while the positive number of mixed infection with GI and GII was 44. Of the NV strains that were cloned and sequenced, GI was GI-3, GI-2 and GI-4 detected in positive specimens respectively; meanwhile, GII-4 was most commonly seen in genome II, followed by GII-3 and GII-7. In addition, the average age of children infected with NV was less than 2 years. An epidemic occurred during the winter and early spring (December through the next March).

CONCLUSIONNV was one of the important pathogens for acute diarrhea among children in Guangzhou, which suggested GII-4 was the prevalent strain.

Objective To retrospectively study revisions for infected total hip replacements in 30 cases and discuss the bacteriological characters of the infected total hip replacements,difficulties and strategies in the revision.Methods Thirty revisions of infected total hip replacements were reviewed retrospectively.There were 12 males and 18 females,with mean age of 62.5 years(31-86 years)at revi- sion surgery.Infection was presented one month to four years(mean seven months)after THA operation. The diseases for initial operation included femoral neck fractures in 12 cases,femoral head necrosis in 11,hip osteoarthritis in five and rheumatoid arthritis in two.Twelve eases were treated by one-stage revi- sion and 18 by two-stage revision.Results Before the revision operation,the hip infection were diag- nosed by bacterial culture in 18 cases including five with Staphylococcus epidermidis,four with Staphylo- coccus aureus and nine with other bacteria.Bacteria growth appeared on the specimens from 23 hip joints during the revision surgery but not on the specimens from seven hip joints.Of 12 one-stage revisions,10 cases were followed for mean 16 months,which showed infection recurrence in two eases.Of 18 two-stage revisions,13 cases were followed for mean 20 months,which showed one case with infection recurrence. The mean Harris hip score was improved from preoperative 44 to 84 at follow-up.Conclusions 1) The main bacteria in the infected hip are antibiotic resistant Staphylococcus.2)Because the revision op- eration is difficult,careful preparation before revision is important for success.The fresh surgeon should not attempt.3)The revision strategies should vary according to specific status of the cases.The infection recurrence rate is lower when using a two-stage revision strategy.4)Application of antibiotic bone cement can help improve treatment effect and facilitate functional recovery of the joints.5)The scientific rehabil- itation after operation is very important to functional recovery.

Objective To report the experience of the application of microsurgery in joint replace- ment.Methods There were 22 cases,10 cases with segmental acetabular defects treated with the pedicle sartorius muscle iliac bone grafting,5 cases with vascular repair following major vascular injury of extremity during operation,6 cases with neural repair following neural injury during operation,1 case with serious injury reconstruction by elbow joint replacement and free flap.Results The operations succeeded in 22 cases without any postoperative infection.The mean follow-up was 40.1 months (3-72 months) in 22 cases,in which the joint function improved and the operative result was satisfactory with no joint pain.Conclusion Microsurgical technique can reconstruct bone and tissue defect effectively in joint replacement.

OBJECTIVETo understand the etiology of hand, foot and mouth disease (HFMD) in Guangzhou area in 2008.

METHODTotally 1023 clinical specimens were collected from pediatric patients suspected of HFMD in 2008. TaqMan real-time RT-PCR were used for detection of enterovirus 71 (EV71), Coxsackievirus A16 (CA16) and other enteroviruses. The specimens which were enterovirus positive by RT-PCR method with universal primer but EV71 and CA16 negative, were amplified and sequenced for 5'untranslated region.

RESULTEnterovirus was identified from 434 of 1023 samples and detection rate of enterovirus was 42.42%; of the 434 samples, 276 were positive for EV71 (63.6%), 126 for CA16 (29%), 4 samples for enterovirus 84, 3 for Echovirus 11, 2 for Echovirus 9, 3 for Coxsackievirus B3, 4 for Coxsackievirus A10, 3 for Coxsackievirus A6, 6 for Coxsackievirus A12 or A5, and for 7 samples typing was difficult.

CONCLUSIONThe major causative agents of HFMD in Guangzhou were EV71 and CA16 in 2008, and EV84, CA10, CA12, CA6, COSB3, ECHV11, ECHV9 were also the pathogens for smaller proportions of patients.
