Background In recent years,with the contiunous progress of the refractive surgery,the operation skill of phakic intraocular lens(PIOL)implantation for correcting extreme high myopia,astigmatism,farsightedness have made greater progression,and its security,effectiveness in clinical attract much more attention. Objective This study was to evaluate the efficacy,safety and stability of Toric Implantable Collamer Lens(TICL)for extreme high myopic astigmatism. Methods This retrospective case series included 33 eyes of 27 patients from May 2008 to February 2009.A TICL was intraocularly implanted via a 3 mm clear corneal incision after paraocular anesthesia.Patients were examined preoperatively and followed-up at 1 day,1 week,1 month,3,6,12 and 18 months postoperatively.The examinations included uncorrected visual acuity,best corrected visual acuity(BCVA),slit lamp examination,refraction,intraocular pressure,endothelial cell morphometry,etc.The written informed consent was obtained from each patient before any medical procedure. Results The uncorrected visual acuity in 96.97% eyes was equal or improved after operation in comparison with BCVA of preoperation.The spherical refraction was within-1.00 D-+0.25 D.The cylinder refraction was within-1.00 D-0 D.The axial deviation of TICL within 10 degree was 93.94%(31/33).No significant differences were found in the intraocular pressure and endothelial cell morphometry between preoperation and postoperation(intraocular pressure:F=3.35,P=5.49;endothelial cell morphometry:t=1.835,P=0.082).The visual acuity and refraction were stable during the follow-up.Astigmatic axial rotation required surgical intervention on one eye.One eye occurred high intraocular pressure because of bigger TICL diameter.The intraocular pressure returned to normal after TICL was exchanged.No cataract occurred during the follow-up duration. Conclusion TICL implantation appears to be an effective,safe and reliable method for extreme high myopic astigmatism.

Human xanthine oxidase is considered to be a target for therapy of hyperuricemia. Cichorium intybus is a Chinese plant medicine which widely used in Xinjiang against various diseases. In order to screen the inhibitors of xanthine oxidase from C. intybus and to explore main pharmacological actions of cichory a compound collection of C. intybus was built via consulting related references about chemical research on cichory. The three-dimensional crystal structure of xanthine oxidase (PDB code: 1N5X) from Protein Data Bank was downloaded.. Autodock 4.2 was employed to screen the inhibitors of xanthine oxidase from cichory 70 compounds were found to possess quite low binding free energy comparing with TEI (febuxostat). C. intybus contains constituents possessing potential inhibitive activity against xanthine oxidase. It can explain the main pharmacological actions of cichory which can significantly lower the level of serum uric acid.

OBJECTIVETo investigate the relationship between the changes of the copy numbers of mtDNA in peripheral blood mono-nucle- ar cell(PBMC) and the disordered of antioxidant capacity of hepatocellular carcinoma (HCC) patients.
METHODSThe Ficoll Hypaque method was used to isolate the PBMC from blood specimens. The ND1 gene of the mitochondrial was amplified by real-time PCR; meantime β-actin was served as a quantitative standard marker; the difference of mtDNA copy number in PBMC was compared between HCC and healthy control group. The level of reactive oxygen species (ROS) in PBMC was determined by flow cytometry. The change of total antioxidant capacity (T- AOC) of plasma was detected by the biochemistry examination.
RESULTSThe copy numbers of ND1 gene in PBMC of HCC was 73% that of the healthy control group,which suggested a decrease of the copy numbers of mtDNA in HCC. The levels of ROS of PBMC in HCC was (417. 82 ± 110.62) and (301.82 ± 75.54) in control group, which showed that the levels of ROS of PBMC in HCC were significant higher than that in control group (P < 0.01).Plasma T-AOC in HCC was (1.30 ± 0.85), and (3.20 ± 1.62) in control. The T-AOC of plasma of HCC was significantly lower than in control group (P < 0.01).
CONCLUSIONThere was a certain relationship between the decrease of the copy numbers of mtDNA and the disordered antioxidant capacity in hepatocellular carcinoma, which may be associated with the development of hepatocellular carcinoma.

OBJECTIVETo measure the effect of atorvastatin on COX-2 expression in monocytes in patients with acute myocardial infarction (AMI).
METHODSForty patients with AMI (AMI group) and 18 patients with stable coronary heart disease (control group) were enrolled, and patients with AMI were randomly given routine therapy (n = 20) and routine therapy plus atorvastatin (20 mg/day, n = 20) for a week. Peripheral blood monocytes for each participant including patients with AMI were isolated and cultured for 24 hours. During the culture, monocytes in patients with pretreatment AMI were incubated with celecoxib in different concentration (0, 0.1, 1 and 10 micromol/L). COX-2 mRNA expression in monocytes was measured by reverse transcription polymerase chain reaction (RT-PCR); concentrations of interleukin-6 (IL-6) in supernatant from monocytes and plasma hs-CRP levels were measured by using enzyme-linked immunosorbent assay (ELISA).
RESULTSCOX-2 expression in monocytes in patients with AMI (0.92 +/- 0.13) was significantly higher than that in the control subjects (0.19 +/- 0.08), and decreased by 66% after atorvastatin (compared with that on routine therapy, P < 0.05); IL-6 secretions of monocytes in the AMI group (204.8 +/- 45.6 ng/L) increased dramatically compared with those in the control group (40.9 +/- 1.2 ng/L, P < 0.05), and reduced dramatically by 58% when incubated with 10 micromol/L celecoxib (P < 0.05) in a concentration-dependent manner; plasma levels of CRP in the AMI group (43.3 +/- 14.9 mg/L) significantly increased compared with those in the control group (1.7 +/- 0.8 mg/L), and reduced by 62% after atorvastatin (compared with those in the routine therapy group, P < 0.05). COX-2 expression in monocytes in the AMI group was positively correlated with both secretions of IL-6 and plasma level of CRP (r = 0.636 and 0.662, respectively, both P < 0.05).
CONCLUSIONSThere is an inflammatory activation in peripheral blood monocytes in patients with early AMI, and the monocytes-derived COX-2 may play an important role in promoting early inflammatory process. Atorvastatin may decrease COX-2 expression in peripheral blood monocytes in patients with AMI and cyclooxygenase-dependent pathway might be correlated with the anti-inflammation mechanism of statin.

OBJECTIVETo investigate the effect of allitridin injection on the expression of human cytomegalovirus (HCMV) immediate-early antigens (IEAs including IE72 and IE86) in human embryonic lung cells.
METHODHCMV AD 169 Virus strain infected cell model (MOI = 2.5 and 0.25, respectively) were established, and then treated with ICm5 and MTC doses of allitridin. Western blot was used to analyze the of IE72 and IE86 expression after the treatment, ganciclovir(GCV, IC50 and 2.3 x IC50) treatment as control.
RESULTNo matter what kind of MOI was used, both IE86 and IE72 antigens' expression was effectively suppressed by allitridin treatment, and the inhibitory rate of IE86 was almost twice of IE72's. Compared with GCV, allitridin had stronger inhibitory effect on IE86 expressing, although its efficacy on IE72 was weaker than GCV.
CONCLUSIONAllitridin could suppress the expression of IE72 and IE86, especially for IE86 expressing, maybe it is ore of key role in the mechanism of allitridin against HCMV.

A new type of floating osmotic pump of dipyridamole was designed in this paper. Apparatus three (Chinese Pharmacopeia 2005, appendix XD) was employed for in vitro dissolution test in order to evaluate the release and floating behavior in a same experiment. The system was optimized using central composite design-response surface methodology; where similarity factor (f2) between the dissolution profile of prepared formulation and the target dissolution profile was taken as dependent factor, usage amount of polyoxyethylene (X1, mg), NaCl (X2, mg) and pore former (PEG4000, X3, %) were taken as independent factors. The optimization model was f2 = -29.3 + 2.35X3 - 0.123X1(2) - 0.046X2(2) + 0.145X1X2 (R = 0.996). It was found that the dissolution profile could match the target dissolution profile under the condition of weight gain 8%-9%, X1 (20-34), X2 (30-57), X3 = 50. It is also found that the minimum usage percentage of pore former is 35.1%. The prediction results of the optimization model were good in the experiments.

OBJECTIVETo investigate the oral health status of undergraduate university students and to guide their oral hygiene behaviors.
METHODS3516 college students in Northwest University for Nationalities were investigated in this study according to the criterion issued by World Health Organization (WHO) on the basic methods of oral health investigation in 1997.
RESULTSThe caries prevalence rate among the students investigated was 47.87%. The average decayed teeth were 1.29. The obturation rate of caries was 20.42%. The students came from city showed significant higher caries rate than those from countryside, and so did the female students compared with the male students. Dental calculus rate was 79.78%. The dental segments related were 3.75. The worst situation was among male students and students from countryside. The examined rates were 53.30% of crowded incisor, 42.58% of maximum upper-incisor anomaly, 50.60% of the maximum lower-incisor anomaly and 31.09% of molar malposition, respectively. More rates of dentofacial anomalies showed no differences of significance between different area and gender.
CONCLUSIONIn general, the oral health status of the college students are not ideal. It is necessary to advocate early examination, early prevention and early treatment among the students in university.
