AlM: To comprehensively evaluate of visual quality after epipolis laser in situ keratomileusis ( EPl-LASlK) in mild to moderate myopia.METHODS: Sixty cases ( 120 eyes ) undergone EPl-LASlK with equivalent diopter ( SE ) were divided into two groups:mild myopia group (60 eyes) and moderate myopia group ( 60 eyes ) . Objective visual acuity, aberration, contrast sensitivity and glare sensitivity were measured before and 1wk; 1, 6mo after operation, and made comparative analysis. RESULTS: Postoperative uncorrected visual acuity ( UCVA ) of two groups were better than that of preoperative(P<0. 05). Postoperative 6mo, there were significant differences on total high RMS between two groups ( P < 0. 05 ). Before operation and 6mo after operation, higher - order aberrations had statistically significant difference between two groups (P<0. 05). After 1wk and 1mo, there were statistical significances at the five frequencies between two groups (P<0. 05). After 6mo, the mild myopia group returned to preoperative levels, however, moderate myopia group in the high frequency region ( 18. 0c/d ) had significant difference with before surgery (P<0. 05). 1wk after surgery, there were statistically significant differences on the 3. 0, 6. 0, 12.0, 18. 0c/d frequency in both groups (all P<0. 05), 1mo after surgery, there were significant difference at 12.0, 18.0c/d frequencies (all P<0.05), after 6mo, both groups returned to preoperative levels, showed no significant difference.CONCLUSlON:Visual quality is poorer in mild myopia patients than that in moderate myopia at early stage after EPl-LASlK. Better visual quality is observed at mid-late stage.

Objective To explore the preventive and therapeutic effects of diminazene (DIZE) on pulmonary arterial hypertension (PAH) in rats.Methods Left pulmonary lobectomy combined with injection of monocrotaline was used to establish a rat model of pulmonary arterial hypertension.One hundred adult male Wistar rats were randomly divided into blank control group (group A,n=20),DIZE control group (group B,n=20),PAH model group (group C,n=20),PAH model plus DIZE group (group D,n=20) and PAH model plus DIZE and C-16 group (group E,n=20).Angiotensin-converting enzyme 2 (ACE2),IL-6 and IL-8 levels were determined by fluorescence resonance energy transfer (FRET) and enzyme linked immunosorbent assay (ELISA),and the mean pulmonary arterial pressure (mPAP) and right ventricular hypertrophy index (RVHI) were measured.The wall thickness (WT) and intimal hyperplasia score were calculated,and the pulmonary vascular lesions were analyzed using elastic fiber staining.Results RVHI,ACE2 enzyme activity and WT in the group A were significantly different from those of the groups C,D and E (P<0.05).Those of the group D and E were significantly different (P<0.05).The five groups showed significant differences in the overall analysis of each index (P<0.05).Conclusions Diminazene can increase the ACE2 enzyme activity,and decrease the mPAP,RVHI and WT,while reducing the pulmonary arterial medial hypertrophy,and inhibit intimal hyperplasia of pulmonary arterioles.The results of this study provide an experimental basis for the use of diminazene in the treatment of human pulmonary hypertension.

The nerve tissue engineering is to apply scalfolds and seed cells for the treatment of injury or disease of nerve system by restoring their anatomic structures and funetiorm.The scaffolds played important roles in supporting and conducting axonal regeneration.They could also limit the in-growth of scar tissue and hence help to build the connection between axonal and target cell.Self-assembling peptide scaffold is one of the excellent material used is nerve tissue engineering.This article reviews the self-assembling peptide based scaffolds for nerve tissue engineering and discusses the unsolved problems in the fields and the trend d the related research in the future.

Objective To make a nationwide external quality assessment for drug sensitivity testing of Neisseria gonorrhoeae, analyze the problems in and factors associated with the drug sensitivity testing, and to enhance the quality of drug sensitivity testing of N. gonorrhoeae at different monitoring sites. Methods Samples were uniformly delivered to monitoring sites by express mail service. Test results were analyzed in the National Center for STD Control, and the evaluation results were fed back to these monitoring sites. Results A total of 105 quality control samples were delivered from 2007 to 2009, with a response rate of 88.57% (93/105). Thirteen monitoring sites were enrolled in the external quality assessment, including 9 laboratories in 2007, 9 in 2008 and 13 in 2009. The total percentage amounted to 77.42% (24/31) for qualified laboratories during the 3 years, including 6 laboratories in 2007, 7 in 2008 and 11 in 2009. The coincidence rate increased for the detection of penicillinase-producing N. gonorrhoeae (PPNG), N. gonorrhoeae with chromosome-mediated ciprofloxacin resistance, and N. gonorrhoeae with chromosome-mediated spectinomycin resistance, and declined for the detection of N. gonorrhoeae with plasmid-mediated high level tetracycline-resistance (TRNG) and N. gonorrhoeae with chromosome-mediated ceftriaxone resistance. Conclusions The 3-year external quality assessment reveals an improvement in the overall quality of drug sensitivity testing of N. gonorrhoeae at national monitoring sites; the accuracy is improved markedly for the detection of PPNG, N. gonorrhoeae with resistance to spectinomycin and ciprofloxacin, but is needed to increase for the detection of ceftriaxone-resis- tant N. gonorrhoeae and TRNG.

OBJECTIVE: To explore the pathological changes of lower extremity arteries of patients with metabolic syndrome. METHODS: Fifty patients with metabolic syndrome (MS) and 30 normal volunteers were included in this study. The inner diameters, peak systolic velocities and intima-media thicknesses of the lower extremity arteries, and the sizes and numbers of the plaques in the lower extremity arteries were obtained with color Doppler ultrasound (CDU). RESULTS: In the fifty MS patients, the intima-media thicknesses of forty-one were thicker than 1.1 mm and thirty-three had plaques which had brought stenosis in different degrees. The intima-media thicknesses of the common femoral, popliteal and posterior tibial arteries in the MS patients were significantly thicker than those in the normal volunteers (P<0.01 or P<0.05), and a greater number of plaques in the lower extremity arteries were observed in the patients, as compared with the normal volunteers (P<0.01). CONCLUSION: Various pathological changes had taken place in the lower extremity arteries of the MS patients. The sites and degrees of the lower extremity arterial diseases in MS patients can be definitely detected with CDU.

[Objective] To observe the effects of Oysters, Abalone shel , Concha arcae, Mother-of-pearl, Concha cypraeae, Clamshel , these six testacean TCM on the goiter rats. [Method] 72 healthy SD rats were randomly divided into nine groups:normal group, model group, positive group and six testacean TCM groups. Rats were given daily propylthiouracil (0.15 g·kg-1), continuous modeling for 10d, weighing thyroid wet weight,assaying T3, T4 and TSH contents in serum by ELISA, observing the morphological changes of thyroid under light microscope. [Result] Rats in the model group compared with normal group in-creased the relative weight of thyroid, reduced the content of T3,T4, and there was a significant difference( P<0.01), thyroid fol icular epithelial cellhyperplasia was obvious;compared with the model group, Oysters and Clamshel group made the content of T3,T4 in rat rebound, and there was a significant difference (P<0.05);Oyster and Clamshel group’s thyroid fol icular cellhyperplasia were not obvious, while the hyperplasia had different levels for the other 4 kinds of testacean TCM. [Conclusion] Oysters and Clamshel were better to improve the thyroid function of the goiter model rats.

[Objective]To explore the clinical effects of titanium plate and morselized hone grafting for the treatment of severe acetabular hone defect.[Method]A total of 27 patients with acetabular defects were treated with this procedure.According to AAOS,the acetabular defects were classified into various types:type Ⅰ in 6 cases,type Ⅱc in 4 and type Ⅲ in 17.The average preoperation Harris score were 37.The postoperative effect should be evaluated by clinical and X-ray manifestations.[Result]All patients were adopted this method to reconstruct the acetabular bone defects.The prosthetic dislocation was found in one case after operation,which was resulted from over-anteverted titanium plate impacted the greater trochanter.The part of trochanteric bone and impact factors were removed to healing.No complications were found in other patients.The average following up was 3 years and average Harris score was 87.The X-ray showed that none of the patients was presented the radiolucent lines in the acetabular mattress,bone transplantation,reconstructive titanium plate and interface of polyethylene liner.[Conclusion]The titanium plate and morselized bone grafting can repair the acetabular bone defects effectively and provide a solid initial fixation for prosthesis and restore the role of rotational center of hip.
