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.

OBJECTIVETo investigate the effects of rhodiola on expression of vascular endothelial cell growth factor (VEGF) and angiogenesis in aortic atherosclerotic plaque of rabbits.

METHODSThirty male New Zealand rabbits were randomly divided into 3 groups equally, i. e. the control group (A) fed with common diet and treated with distilled water, the high fat diet group (B) and the rhodiola group (C) fed with diet containing 1.5% cholesterol and treated respectively with distilled water and rhodiola (1 mL/kg per day), all the treatments were administered via gastrogavage once a day for 9 successive weeks. Level of blood lipids in various groups was determined and compared at the end of the experiment. Meanwhile, the tissue sample of aorta was taken for observation through HE and Sudan red staining, for detecting the CD34 positive response intensity by immunohistochemical staining and the VEGF expression by Real-time fluorescent quantitative PCR and Western blot.

RESULTSDetermination of blood lipids showed that in Group C, TC was 42.01 +/- 1.99 mmol/L, TG 4.83 +/- 0.75 mmol/L and LDL-C 38.40 +/- 0.74 mmol/L, all lower than those in Group B (70.74 +/- 2.66 mmol/L, 8.75 +/- 0.78 mmol/L and 51.05 +/- 0.34 mmol/L, respectively), showing statistical difference between groups (P < 0.05). The intima/media tunica thickness ratio and the CD34 positive area of plaque in Group C were all lower than those in Group B (0.35 +/- 0.03 vs 0.43 +/- 0.03 and 29.12 +/- 2.56% vs 39.28 +/- 3.48%, P <0.05). Besides, the VEGF expression in atherosclerotic plaque was also lower in Group C than that in Group B.

CONCLUSIONRhodiola has the effects of inhibiting atherosclerosis formation, decreasing the VEGF expression and suppressing the angiogenesis in the plaque.

OBJECTIVETo investigate the effects of Shexiang Baoxin Pill (SBP) in intervening atherosclerosis and myocardial infarction (AS-MI) in experimental animals, and inspect its influences on angiogenesis.

METHODSTwenty male New-Zealand rabbits were made into AS-MI model, and randomly divided into 2 groups equally. Group A was fed with high-fat diet for control; Group B was fed with high-fat diet but intervened with SBP. The cardiac function and the positive area of plaque were determined. The CD34 positive response intensity at infarcted marginal zone and aorta vessel wall, and the capillary density of myocardium were measured by immunohistochemical staining. In addition, the protein expressions of vascular endothelial growth factor (VEGF) and vascular endothelial growth factor receptor-2 (VEGFR-2) were detected by Western blot.

RESULTSCompared to Group A, the cardiac function was obviously improved (P<0.05) and the plaque positive area (%) was significantly decreased in Group B (45.82 +/- 3.68 vs 82.56 +/- 4.97, P<0.01). The CD34 positive response intensity and the capillary density as well as VEGF and VEGFR-2 expressions in infarcted marginal zone in Group A were higher than those in Group B (P<0.01); but these parameters at aorta vessel walls were lower in Group A than in Group B (P<0.01).

CONCLUSIONSBP could advance the angiogenesis in the marginal zone of infarction, improve heart function, and embarrass angiogenesis in atherosclerotic plaque.

OBJECTIVETo study modified ilioinguinal approach through the retrospective analysis on the surgical treatment of 63 patients with pelvic and acetabular fractures through anterior approach.

METHODSFrom January 2006 to January 2013, 63 patients with pelvic and acetabular fractures were treated with the ilioinguinal anterior approach, including 45 males and 18 females, ranging in age from 12 to 68 years old, with an average of (37.71 +/- 13.41) years old. All the patients were divided into two groups: standard ilioinguinal anterior approach group (group A) and modified ilioinguinal anterior approach group(group B). In group A, there were 26 males and 11 females, with an average age of (38.49 +/- 13.64) years old. In group B, there were 19 males and 7 females, with an average age of (36.62 +/- 13.29) years old. Intraoperative and postoperative indicators in group A and B were observed and compared, including operation incision exposure time (from skin incision to complete the ilioinguinal in front of three "windows"), the blood loss, incision close time and treatment effect of Majeed function score.

RESULTSCompared to group A, the incision exposure time of patients in group B was shorter, the blood loss (bleeding during exposure process) was less, and the close incision time was shorter, but the treatment effect of Majeed function score had no significant differences between two groups. All the patients were followed up, and the during ranged from 3 to 36 months, with an average of (18.6 +/- 9.2) months. According to Matta standard assessment reduction of pelvic and acetabular fracture, there were 28 patients got an excellent result, 8 good, and 1 fair in the group A; and 20 patients got an excellent result, 5 good, and 1 fair in the group B. According to Majeed function score for hip function, 20 patients got a satisfactory result, 12 good,4 fair and 1 poor in group A, and the mean score was 82.51 +/- 9.72; and 13 patients got an satisfactory result, 10 good, 3 fair and 0 poor in group B, and the mean score was 80.54 +/- 10.79.

CONCLUSIONThe modified approach has several advantages as follows: providing a good surgical exposure; preventing from the injury of femoral nerve, femoral artery and vein under the inguinal ligament; not needing to open the inguinal canal, which can avoid the occurrence of inguinal hernia, reduce operation prodedures and shorten operation time.

Objective To observe skin test results of tetanus antitoxin prepared by different solvents.Methods Patients who needed injecting tetanus antitoxin as required by trauma were randomly divided into two groups, Group A and Group B, respectively. Group A was administered with tetanus antitoxin prepared by water for injection, while Group B with tetanus antitoxin prepared by saline. Skin test results were observed, the incidence of positive skin test results and self-inductance of pain intensity were compared.Results The incidence of positive skin test results in Group A was significantly higher than that in Group B (34.19% vs 17.50%,χ2=8.631,P<0.01), and the self-inductance of pain intensity were also greater than that in Group B. Patients with positive skin test results (40 patients) in Group A, were later injected tetanus antitoxin prepared by saline, 42.50% of them (17 patients) shown negative skin test results.Conclusions There might be a high false positive rate by using tetanus antitoxin prepared by water for injection; therefore tetanus antitoxin prepared by saline is recommended, for it could decrease the false positive rate, reduce unnecessary desensitization injections, alleviate patients' pain and improve nurses' work efficiency.

This study was aimed to investigate the clinical feasibility of using multiplex PT-PCR assay for screening rare/cryptic chromosome translocations in patients with de novo acute myeloid leukemia. For 126 patients with de novo AML-M4/M5 without common chromosome translocations including t(15;17), t(8;21) and t(16;16), 3 parallel multiplex RT-PCR assays were set up to detect 6 mll-related gene rearrangements (mll/af10, mll/af17, mll/ell, mll/af9, mll/af6 and mll/enl) with low detection rate and 4 rare fusion genes (dek/can, tls/erg, aml1/mds (evi1) and npm/mlf1). The results showed that 11 patients with positive result from 126 patients were detected which involved in 5 molecular abnormalities. Among them, 10 cases were AML-M5 (16.67%), 1 cases AML-M4 (1.51%). The marker chromosomes were observed in 2 cases out of 11 cases through conventional karyotyping analysis, the karyotyping analysis in 1 case was not performed because this case had 1 mitotic figure only, no any cytogenetic aberrations were found in other 8 cases through R-band karyotyping analysis. It is concluded that multiplex RT-PCR designed in this study can quickly, effectively and accurately identify the rare/cryptic chromosome translocations and can be used in clinical detection.

OBJECTIVETo study the significance of plasma D-dimer and von Willebrand factor (vWF) and the therapeutic effect of compound glycyrrhizin in children with cytomegalovirus (CMV) hepatitis.

METHODSTwenty healthy children, 16 asymptomatic cases with CMV infection and 52 cases of CMV hepatitis (21 cholestatic and 31 non-cholestatic) were enrolled. The 52 children with CMV hepatitis were randomly administered with conventional treatment alone or conventional treatment plus compound glycyrrhizin treatment. Plasma D-dimer and vWF levels were measured before and after treatment.

RESULTSPlasma D-dimer and vWF levels in the CMV hepatitis group were markedly higher than those in the healthy control and asymptomatic CMV infection groups (P<0.01). The cholestatic hepatitis group had more increased plasma D-dimer and vWF levels compared with the non-cholestatic hepatitis group (P<0.01). Plasma D-dimer and vWF levels in the CMV hepatitis group were markedly reduced after conventional or compound glycyrrhizin treatment (P<0.01). Compound glycyrrhizin treatment decreased more significantly plasma D-dimer and vWF levels compared with the conventional treatment in children with CMV hepatitis (P<0.01).

CONCLUSIONSThe detection of plasma D-dimer and vWF is useful in the early assessment of liver damage in children with CMV hepatitis. Compound glycyrrhizin can decrease obviously plasma D-dimer and vWF levels and might thus provide protective effects against liver damage.
