BACKGROUND:Lymph-targeted tracing and therapy based on carbon nanotubes have been one of the hottest researches on targeting tumor diagnosis and treatment. To evaluate the accumulation of carbon nanotubes in axil ary lymph node can provide experimental evidences for developing nano-tracers and drug carriers which are more lymph-specific and more biocompatible. OBJECTIVE:To study the accumulation of the intravenously injected carboxylated single-wal ed carbon nanotubes in axil ary lymph nodes of Sprague-Dawley rats, and to evaluate their effect on blood cel s. METHODS:Sixty-four Sprague-Dawley rats were randomly divided into two groups. Rats in testing group were injected with carboxylated single-wal ed carbon nanotubes suspension (2 mg/kg), while those in control group were injected with 5%glucose solution (1 mL/kg), both through the tail vein, three times per week. Four periods of 7, 60, 90 and 120 days were set (the 120-day period referred to 90 days of administration fol owed by 30 days of drug withdrawal). At the end of each period, eight rats from each group were randomly picked out, to col ect blood samples via the abdominal aorta for blood routine test. Final y the axil ary lymph nodes were observed, and the lymph node samples of rats in the testing group were col ected and analyzed at 120 days by transmission electron microscope. RESULTS AND CONCLUSION:Compared with the control group, black staining of axil ary lymph nodes of rats in testing group was not obvious at the end of the 7-day period. However, with the increase of the dosing periods, the lymph nodes of the rats in the testing group became enlarged, firm and black stained, coupled with a significant rising in the percentage of blood neutrophils. After 30 days of drug withdrawal, the size of the rat axil ary lymph nodes was reduced and black staining partly faded, with the decreasing of blood neutrophil percentage. Under the transmission electron microscope, abundant carboxylated single-wal ed carbon nanotubes were uptaken by lymphocytes to form a large number of phagocytic vacuoles after drug withdrawal for 30 days. It indicates that the short-term tracing of rat axil ary lymph nodes by carboxylated single-wal ed carbon nanotubes injected through the tail vein is relatively weak, while the long-term intravenous injection can cause their accumulation in rat axil ary lymph nodes, coupled with the increase of neutrophils;after drug withdrawal, the carboxylated single-wal ed carbon nanotubes can be slowly cleared by the lymph nodes.

OBJECTIVE To investigate drug resistant genes associated with beta-lactamases,aminoglycosides and sulfonamides in Pseudomonas aeruginosa isolated from burned patients.METHODS Common drug resistant genes associated with beta-lactamases,aminoglycosides and sulfonamides of 20 strains of P.aeruginosa isolated from burned patients were detected by PCR.RESULTS The positive rates of genes of TEM,aac(6′)-Ⅰb,sul1 and ant(3″)-Ⅰwere 85%,85%,90% and 10%,respectively and genes of CARB and aac(6′)-Ⅱ were both positive(100%).Genes of oprD2 were all absent and genes of SHV,GES,IMP,VIM,DHA and armA were all negative.Furthermore,drug resistant genes of strains isolated from different sites of one patient on different time could be different.CONCLUSIONS Drug resistant genes of CARB and aac(6′)-Ⅱprevail in P.aeruginosa isolated from burned patients.Detections of drug resistant genes in P.aeruginosa isolated,especially continuously isolated from burned patients are essential.

Background Sirius system,a new Scheimpflug camera combined with Placido topography,improved the capability of imaging the anterior eye segment significantly.However,the study of assessing the repeatability and agreement between Sirius and Pentacam is still lack up to now.Objective This study was to evaluate the repeatability and agreement of the anterior ocular segment measuring parameters by Sirius and Pentacam in myopia received laser in situ keratomileusis (LASIK).Methods Thirty-five myopic eyes of 35 patients received LASIK were included in School of Optometry and Ophthalmology Eye Hospital from 2010 May through 2010 July.Corneal power flat keratometry (Kf),step keratometry (Ks),mean keratometry (Km),thinnest corneal thickness(TCT),the location of TCT,anterior chamber depth (ACD) and anterior chamber volume (ACV) were measured by Sirius and Pentacam in all the eyes,respectively.The repeatability of the measuring results were evaluated using intraclass correlation coefficients (ICC) and Cronbach's coefficient alpha (CoA),and the agreement of measuring parameters between Sirius and Pentacam was analyzed using Bland-Altman plot.Results Both Sirius and Pentacam demonstrated high intraobserver repeatability,with all ICC and CoA more than 0.90.No significant differences were found in Kf values and Ks values between the two methods (t =-1.533,-1.750,P＞0.05).Km value was (39.14 ± 1.95) D by Sirius measurement,which was sígnificantly higher than (39.05 ± 1.91) D by Pentacam measurement (t =3.572,P =0.001).The TCT was (457.6 ± 40.9) μm by Sirius method,showing a significant reduce in comparison with (465.4±37.5) μm of Pentacam method (t =-6.689,P＜0.001).A positive correlation was seen in the TCT between the two methods (r=0.988,P＜0.001).The Bland-Alrman plots showed the 95％ CI-21 μm to 6 pm in the TCT value between the two devices.Pairwise comparison of the location of TCT measurements showed significant differences between the two devices (t =-4.132,-5.696,P＜0.001),with a good correlation (r=0.751,0.775) and the 95％ CI (-0.36-0.17 mm,-0.35-0.12 mm).A very good agreement was seen in ACD between the two devices (-0.02-0.12 mm),but the agreement result was not very well in the ACV between the two devices with the 95％ CI (-27.70-6.20 mm3).Conclusions Sirius and Pentacam measurements for anterior ocular segment parameters have a very good repeatability in post-LASIK eyes.In addition,good agreement results are exhibited in corneal power,TCT and ACD between Sirius and Pentacam with an acceptable maximal different value between them.Sirius and Pentacam can be used interchangeably in clinical examination.However,the two devices can not interchangeably for ACV measurement and TCT location.

Objective To investigate the effectiveness and safety of low-intensity warfarin anticoagulation in over 80-year-old patients with nonvascular atrial fibrillation (NVAF). Methods The 180 NVAF patients aged over 80 years were randomly assigned into 2 groups: 90 patients in lowintensity warfarin anticoagulation group (target value of INR 1.6-2.0), the other 90 patients in standard-intensity warfarin anticoagulation group (target value of INR 2. 0-3.0). All patients were followed up in outpatient-department for one year. Main outcome measures included the incidence rates of bleeding and thromboembolic events, and secondary outcome measures included the warfarin dosage and times of INR＞3.0. Results The incidence rate of thromboembolic events was 4.4% (4/90) in low-intensity group and 3.3% (3/90) in standard-intensity group with no statistically significant difference between these two groups (P＞0. 05). However, the incidence rate of hemorrhage was significantly lower in low-intensity group than in standard-intensity group [5.6% (5/90) vs. 16.7%(15/90), P＜0. 05]. Meanwhile the warfarin dosage was significantly lower in low-intensity group than in standard-intensity group [(1. 55±0. 63) mg vs. (2.31±0.57) mg, P＜0.05]. The times of INR＞3.0 were less in low-intensity group than in standard-intensity group (P＜0. 05). Conclusions Therapy with low-intensity warfarin anticoagulation in NVAF patients aged over 80 years may be equally effective as, but safer than that with standard-intensity warfarin.

The role of pulchinenoside (PULC) in the regulation of MeCP2 expression was investigated in RA model rats. Adjuvant arthritis rats were used as RA model rats, and fibroblast-like synoviocytes (FLS) from the RA model rats were cultured. The effect of 100 mg x kg(-1) PULC gavage treatment on the MeCP2 expression and the effect of MeCP2 siRNA on the expression of SFRP2 and β-catenin were detected by real time qPCR and Western blotting. The role of PULC in the FLS proliferation was detected by MTT. The results showed that the MeCP2 expression was down-regulated, the SFRP2 expression was up-regulated and the FLS proliferation was inhibited in FLS after therapy. MeCP2 siRNA significantly inhibited the MeCP2 expression, up-regulated the SFRP2 expression and inhibited the β-catenin expression in FLS from RA model rats. PULC may increase the SFRP2 expression, inhibit the Wnt signaling and inhibit the FLS proliferation in FLS from the RA model rats by inhibiting the MeCP2 expression.

To study the effect of pulchinenoside (PULC) on the Frizzled (FZD) expression of adjuvant arthritis ( AA) rats. AA rats were prepared through the toe injection with complete Freund's adjuvant to culture fibroblast-like synoviocytes (FLS). The effect of the oral administration with PULC on the FZD8 expression was detected by the real time qPCR. The effect of FZD8 knockout on the expressions of IL-1, IL-6, IL-8 were detected by MTT and ELISA. The role of miR-375 in the abnomal expression of FZD8 was detected by the real time qPCR. The results showed signfiicant decrease in the FZD8 expression among AA rats, FLS proliferation ater FZD8 knockout and IL-1, IL-6, IL-8 expressions and notable increase in miR-375 expression after the oral administration with PULC. The up-regulated miR-375 expression can inhibit the FZD8 expression. PULC may inhibit the FZD8 expression by up-regulating the miR-375 expression.
