AIM: To evaluate the clinical effect and the rotational stability of AcrySof Toric intraocular lens ( IOL ) implantation to correct preexisting corneal astigmatism in cataract surgery.
METHODS: Twenty-three patients ( 28 eyes ) were enrolled from the department of ophthalmology in the first Affiliated Hospital of Nanjing Medical University. All patients underwent similar phacoemulsification procedure combined with AcrySof Toric IOL implantation from June 2012 to December 2013. The uncorrected visual acuity ( UCVA ) , best corrected visual acuity ( BCVA ) , anticipated residual astigmatism, postoperative residual astigmatism, and Toric IOL axis were detected and measured.
RESULTS:Three months after operation, the UCVA of all eyes were 0. 75±0. 16 and the BCVA were 0. 84±0. 15, there was no significant difference between UCVA and BCVA ( t = 1. 036, P>0. 05 ). The anticipated residual astigmatism was ( 0. 28±0. 12 ) D. The actual residual astigmatism after 3mo of the operation was (0. 42±0. 17) D. There was no significant difference between anticipated and actual residual astigmatism (t=1. 259, P>0. 05). The mean axis rotation of Toric IOL was 3. 02o±1.56o (0o-7o) after 1d of operation and 3. 28o±1. 85o (0o-7o) after 3mo. Among all the eyes, 25 eyes ( 89%) rotated <5o, in 3 eyes (11%) rotated 5o-7o.
CONCLUSION: The AcrySof Toric IOL implantation shows good effectiveness, predictability and stability in correcting pre-existing astigmatism in cataract patients.

OBJECTIVETo observe the antifebrile effect of Naoreqing (NRQ) oral liquid on secretive function of vaso-endothelial cells in rabbits with endotoxic fever.

METHODSEndotoxic fever rabbit model was duplicated to observe the effects of NRQ on body temperature, blood levels of thromboxane B2 (TXB2), 6-keto-prostaglandin F1alpha (6-keto-PGF1alpha) and endothelin (ET) using radioimmunoassay, as well as activity of tissue-type plasminogen activator (t-PA) and plasminogen activator inhibitor (PAI) in plasma by chromophoric substrate assay.

RESULTSComparisons of various indexes between the two groups showed significantly difference, i.e. the maximal increment of body temperature: 0.69 +/- 0.07 degrees C vs 1.31 +/- 0.13 degrees C (the NRQ treated group vs the untreated model group, the same hereafter); 2h thermal response index TRI2 4.85 +/- 0.57 vs 8.44 +/- 0.98; plasma ET content 197.96 +/- 39.11 ng/L vs 250.80 +/- 40.99 ng/L; TXB2 content 177.35 +/- 77.30 ng/L vs 279.64 +/- 83.74 ng/L; activity of PAI 0.84 +/- 0.01AU/ml vs 0.86 +/- 0.01 AU/ml; plasma 6-keto-PGF1alpha content 986.70 +/- 327.36 ng/L vs 507.81 +/- 170.01 ng/L; activity of t-PA 0.25 +/- 0.02 IU/ml vs 0.21 +/- 0.02 IU/ml (P < 0.05, P < 0.01).

CONCLUSIONNRQ may improve secretive function of vaso-endothelial cells to dilate blood vessel and quicken heat dissipation through body surface, so as to play an integral antipyretic effect in rabbits with endotoxic fever.

Objective To establish an easy culture method of successively getting high purity and yield of microglia. Methods Cortices of neonatal Wistar rats (1-3 days old) were employed in this experiment. The first-generation microglial cells were isolated from the mixed glial culture by mechanical means (gently shaking and blowing with pipette). After the mixed glial cells being passaged at a density third generations ofmicroglial cells were harvested. CD1 lb/c, CD45, CD80, CD86 and GFAP were employed as the identification markers in detecting the phenotypes and purity of different generation of microglial cells by scanning electron microscope and flow cytometry. Immunofluorescence staining and CCk8 vitality measurement were used to judge the expression of CD11b/c and detect the proliferation of microglia cells. Microglial phagocytotic function was evaluated by phagocytosis of fluorescent microspheres. Results High yield and purity of microglial cells were stably obtained in this experiment. CD11b/c, CD45, CD80 and CD86 positive expressions were noted in the first and third generations of microglial cells by flow cytometry; CD1 1b/c positive expression was noted in the first,second and third generations of microglial cells by immunofluorescence staining. No obvious differences in the 3 different generations of microglia cells were found on proliferation ability by CCk8 vitality measurement, and on morphology and phenotypes by scanning electron microscope; no obvious differences in the first and third generations of microglia cells were found on phagocytic ability (P＞0.05).Conclusion High yield and purity of microglial cells can successively obtain through the above method;no significant differences are noted among different generations of microglia cells on purity, morphology,phenotypes, proliferation activity and phagocytic ability.

OBJECTIVESTo screen differential proteins in serum from hepatocellular carcinoma (HCC) patients by Proteomic Technology and to purify and identify them.

METHODSSurface enhanced laser desorption Ionization time of flight-mass spectrum (SELDI-TOF-MS) was employed to screen differential proteins in serum from 33 HCC patients and 33 control cases, and then to purify and identify them using isoelectric precipitation, Tricine sodium dodecyl sulphate polyacrylamide gel electrophoresis (Tricine-SDS-PAGE) and high performance liquid chromatography tandem Mass Spectrum (HPLC-MS).

RESULTS65 protein peaks in the range of relative molecular weight from 2,000 to 10,000 were found significant difference (P less than 0.05) between the patient group and control group. Based on these differential protein peaks, diagnostic model for HCC detection was established and its sensitivity and specificity were 100% and 96.97% respectively. Proteins with 8,706.5 and 8,579.2 relative molecular weights (the t value was 2.562 and 2.783 respectively, and P value was 0.013 and 0.015 respectively) out of the 65 differential proteins were purified and identified, and then recognized as Apolipoprotein AII (Apo AII).

CONCLUSIONApo AII is probably a differential protein of HCC and maybe related to the pathogenesis of HCC.

OBJECTIVETo investigate the clinical characteristics of patients with idiopathic pulmonary arterial hypertension (IPAH) in China.

METHODSA total of 161 patients diagnosed as IPAH in Shanghai Pulmonary Hospital from June 2008 to June 2010 were retrospective analyzed.

RESULTSThe mean diagnostic age was (33 ± 15) years old and 70.2% patients were female. The median duration from symptoms onset to diagnostic right heart catheterization was 12 months. Incidence of NYHA class III to IV was 56.5% at diagnosis and the mean six minutes walk distance was limited to (398 ± 108) meters. Incidence of mild obstructive, restrictive and diffusing impairment in pulmonary function test was 7.8%, 42.2% and 82.2% patients with IPAH, respectively. Right heart catheterization demonstrated severe elevated mean pulmonary arterial pressure [(63 ± 17) mm Hg (1 mm Hg = 0.133 kPa)] and pulmonary vascular resistance index [(25 ± 12) Wood U/m(2)] in this patient cohort. The response rate of acute pulmonary vasoreactivity testing was 8.7% in this cohort. Compared with non-responders, responders to acute pulmonary vasoreactivity testing were younger and with less severe pulmonary hypertension. Among non-responders, 89% patients were treated by one specific anti-pulmonary arterial hypertension drug and 27% patients received combined anti-pulmonary arterial hypertension medications.

CONCLUSIONSYoung female was predominantly involved in patients with IPAH in China. The diagnosis of IPAH is often made at advanced disease stage and majority patients with IPAH received specific anti-pulmonary arterial hypertension therapies in this patient cohort.
