Objective Base on the neighborhood activation model(NAM), to develop the Mandarin monosyllable lexical neighborhood test(M-LNT-monosyllable), which is expected to be useful for evaluating speech perception performance in children with hearing loss. Methods Test items were based on the lexical characteristics of word frequency and neighborhood density which addressed in the neighborhood activation model (NAM). M-LNT -monosyllable consisted of two parts: Lexically "easy" words with high word frequency, which were low phonemically similar to the target word and lexically "hard" words with low word frequency, which were high phonemically similar to the target word. 34 children of 3~5 year old with normal hearing were choosed as subjects to verify easy word and hard word lists. Results 1 979 words for children contained 487 easy words and 419 hard words. Three easy word lists and three hard word lists were developed to estimate the performance of word recognition among normal- hearing children. There were no differences among scores of three easy words lists(P>0.05), and no difference among scores of three hard words lists(P>0.05). But there were significant differences between scores of easy and hard words lists(P<0.01). Conclusion The development of the lexicon was affected by the lexical characteristics. Normal-hearing children with some lexical techniques were affected by the lexical characteristics when they recognized the spoken words, but children with less lexical technique didn't show the same result because the recognition was processed on the phonetic level.

Recombinant RGD-Hirudin ( r-RGD-Hirudin ) has double functions: anti-thrombin activity and anti-platelet aggregation activity. To identify these functions, the expression plasmid, RGD-Hirudin-pPIC9K, was constructed by inserting cDNA of RGD-hirudin in yeast expression vector pPIC9K. The high expression clone was gained after screening. This clone was fermented for 3 days. The r-RGD-hirudin was secreted into the culture. It was ultra-filtrated from culture supernatant, then after gel filtration chromatography and anion exchange chromatography, the purified r-RGD-hirudin was gained. Its purity was larger than 97% and its specific activity was 12 000 ATU/mg. The yield per liter culture of purified r-RGD-hirudin was 1 g and overall recovery yield was more than 75% . The purified r-RGD-hirudin was identified by reductive SDS-PAGE, anti-thrombin activity assay, anti-platelet aggregation assay, LC/MS and isoelectrofocusing assay. It is proved that r-RGD-Hirudin is ramification of wt-Hirudin and it has anti-thrombin activity and anti-platelet aggregation activity.

OBJECTIVETo summarize the experience of repair and reconstruction of penile defects as a result of devastating deep burn.
METHODSTwenty-four patients with penile defects in early or late (a half year after wound healed, the same below) stage after burn were involved. Their suspensory ligaments of penis were dissected to lengthen the penis after escharotomy with the necrotic distal part removed. The wounds formed after lengthening were covered with lower abdominal skin flap, scrotal or internal pudendal artery flap. Ten patients underwent surgery within 30 days after burn; the other 14 patients underwent surgery in the late stage. The condition of flaps and complications after surgery were observed. The lengths of penis of patients in flaccid and erection state were measured before surgery and at follow-up period. The sensory function of penile skin, the erectile function of the penis, and sexual intercourse activity of patients were followed up.
RESULTSAll the flaps survived except two, in whom areas of 1.0 cm x 0.5 cm and 1.5 cm x 1.0 cm of necrosis at distal parts were found, and they healed after dressing changes. Patients were followed up for 2 to 5 years. The length of penis in flaccid state was (7.4 +/- 1.6) cm, which was (5.3 +/- 1.4) cm longer than that before surgery (P < 0.01). The length of penis in erection state was (9.7 +/- 1.2) cm. The sensory function of penis recovered gradually about half year after surgery with well preserved erectile function. Except one who did not try to have sexual intercourse again, all the other married patients and their spouses were satisfied or quite satisfied with sexual intercourse activity.
CONCLUSIONSPenis elongation combined with skin flap grafting is a good method for the treatment of penile defects due to devastating deep burn. Suitable length and erectile function of penis can be preserved with this method.

Objective To evaluate the efficacy and potential renal impairment of one-year combination therapy de novo of adefovir dipivoxil(ADV) and lamivudine(LMV) for decompensated cirrhosis related to HBV. Methods A total of 36 patients with decompensated cirrhosis related to HBV, nobody had nucleos(t)ide analogs(NAs) treatment history, were recruited and were divided into two group(control group and observation group) randomly. A monotherapy of LMV (100 mg per day ) was selected to individuals in control group(n = 18), in contrast, a combination therapy de novo of ADV( 10 mg per day) and LMV( 100 mg per day) was applied to those in observation group( n = 18). Basic approaches including liver protection, symptom-driven intervention, and supporting therapy, were given to all of the individuals. A course of one year was applied to all. Liver function, Child-Pugh score, serum creatinine(sCr) level,virological response(VR) rate, and virological breakthrough rate were observed pro- and post- treatment, differences between the two populations were analysed statistically. Results ( 1 ) The averages of gender,age, HBeAg status, HBV viral load, sCr level, and Child-Pugh score were all compatible in the two groupsat baseline( P ~ 0. 05 for all). (2) At the endpoint of treatment, none of deaths was reported. Comparing with the status before treatment in each group itself, liver function, Child-Pugh score, and viral load were improved statistically (P <0. 01 for all), especially in observed group( P <0. 01 for all variables, vs control group), as for VR rate, result is significant superior to that of control group too(88. 89% vs 66. 67% , P <0.05). (3) Virological breakthrough occurred to none in observed group and three cases (16. 67% ) in control group, all of them were confirmed to be rtM204V variant in the following detection of direct sequencing. (4) Elevated level of sCr didn't arised at the end of treatment in two groups. Conclusion Present study reveals that in populations with decompensated cirrhosis related to HBV, one-year combination therapy de novo of ADV and LMV is superior to monotherapy of LMV, and the renal safety is favorable within one year.

OBJECTIVETo explore the effects of the combined method of abdominal axial flap transposition and penile elongation for the treatment of the remnant penis.
METHODSFifty-two cases of the remnant penis treated with the combined method from 1984 April to February 2004 were analyzed retrospectively. Follow-up ranged from 0.5 to 20 years postoperatively.
RESULTSThe lengths (both in normal and erectile conditions) and the circumferences of the penis gained after operation were (5.6 +/- 1.4) cm, (6.8 +/- 2.5 cm and (6.9 +/- 2.3) cm respectively. The recovery rates of the sensory function were 94.2% and 100% in the glans (immediately and 3 months after operation) and 32.7%, 51.9% and 75% in the flap area (3, 6 and 12 months postoperatively). The two-point distinguishing sense in the glans and the flap area was (5.1 +/- 0.9) mm and(7.9 +/- 1.3) mm 5 years after operation. Early complications included distant flap necrosis (3 cases), disruption of the wound (2 cases), part necrosis of the skin graft in the abdominal wall (2 cases) and poor contours occurred in 4 cases in the later period because of the thickness of the flaps. All of them were corrected with satisfactory results.
CONCLUSIONThe combined method of abdominal axial flap transposition and penile elongation was recommendable for the treatment of the remnant penis because of its positive effects and less complications.

OBJECTIVE:
To determine the effect of different doses of atorvastatin on the serum soluble intercellular adhesion molecules-1 (sICAM-1) in patients undergoing percutaneous coronary intervention (PCI).
METHODS:
The study consisted of 38 patients with unstable angina and 10 patients with old infarction who underwent elected PCI for stenotic lesions of the coronary artery. Patients were randomly assigned to either aggressive group or conventional one. After PCI the patients took atorvastatin 20 mg per day or 10 mg per day. Blood lipid profile was examined before, and 3 months after the PCI. SICAM-1 was examined before the PCI, 48 hours and 3 months after the PCI.
RESULTS:
The total cholesterol and LDL-Cholesterol 3 months after the PCI in the 2 groups were lower than those before the PCI (P<0.01). The aggressive group showed greater reduction in concentrations of TC and LDL-C than the conventional group (P<0.01). The changes in concentrations of HDL-C between pre-PCI and 3 months after the PCI and TG were not obvious (P>0.05). sICAM-1 in the 2 groups 48 hours after the PCI significantly higher than that before the PCI (P<0.01). But sICAM-1 in the 2 groups 3 months after the PCI significantly lower than that before the PCI (P<0.01 or P<0.05). The aggressive group showed greater reduction than the conventional group (P<0.01). TC and LDL-C were positively correlated with sICAM-1(r=0.2413, r=0.2691, all P<0.05).
CONCLUSION
Atorvastatin 20 mg per day reduces TC, LDL-C, and sICAM-1 to a greater extent than atorvastatin 10 mg per day. The effect on sICAM-1 is partly related to reduce lipid profile.

BACKGROUNDThe genome of the severe acute respiratory syndrome-associated coronavirus (SARS-CoV) includes sequences encoding the putative protein X4 (ORF8, ORF7a), consisting of 122 amino acids. The deduced sequence contains a probable cleaved signal peptide sequence and a C-terminal transmembrane helix, indicating that protein X4 is likely to be a type I membrane protein. This study was conducted to demonstrate whether the protein X4 was expressed and its essential function in the process of SARS-CoV infection.
METHODSThe prokaryotic and eukaryotic protein X4-expressing plasmids were constructed. Recombinant soluble protein X4 was purified from E. coli using ion exchange chromatography, and the preparation was injected into chicken for rising specific polyclonal antibodies. The expression of protein X4 in SARS-CoV-infected Vero E6 cells and lung tissues from patients with SARS was performed using immunofluorescence assay and immunohistochemistry technique. The preliminary function of protein X4 was evaluated by treatment with and over-expression of protein X4 in cell lines. Western blot was employed to evaluate the expression of protein X4 in SARS-CoV particles.
RESULTSWe expressed and purified soluble recombinant protein X4 from E.coli, and generated specific antibodies against protein X4. Western blot proved that the protein X4 was not assembled in the SARS-CoV particles. Indirect immunofluorescence assays revealed that the expression of protein X4 was detected at 8 hours after infection in SARS-CoV-infected Vero E6 cells. It was also detected in the lung tissues from patients with SARS. Treatment with and overexpression of protein X4 inhibited the growth of Balb/c 3T3 cells as determined by cell counting and MTT assays.
CONCLUSIONThe results provide the evidence of protein X4 expression following SARS-CoV infection, and may facilitate further investigation of the immunopathological mechanism of SARS.
