?AlM:To investigate the sensitive parameters of the anterior chamber changes with Pentacam anterior segment analysis system before and after laser peripheral iridectomy (LPl) in primary angle-closure suspetive (PACS).
? METHODS: Sixty eyes of 33 PACS patients were enrolled in this study. Pentacam examination was performed before and 1d after LPl to measure the central anterior chamber depth ( CACD ) , the peripheral anterior chamber depth ( PACD ) , the anterior chamber volume ( ACV) and the peripheral anterior chamber angle ( ACA) . Statistical analysis used paired t test.
?RESULTS: There was no statistical significance on the changes of ACD. PACD and ACV increased significantly between before and 1d after LPl. ACA was widened from (22. 26o±5. 18o) to (26. 42o±5. 20o), which were increased significantly between before and 1d after LPl.
?CONCLUSlON: LPl can deepen the PACD and increase the ACV in PACS. PACD and ACV are the sensitive parameters of the anterior chamber changes with Pentacam anterior segment analysis system.

In this case-control study, the effect of insulin sensitivity on the genesis of cholesterol gallstones was not affirmed. However, raised 2h insulin level during glucose tolerance test and systolic blood pressure were risk factors in gallstone formation. Besides, less physical activity, lower serum total cholesterol and lower HDL-C concentration were found in patients with cholesterol gallstone.

Background Posterior capsular opacification (PCO)affects the pseudoaccommodation of 1CU accommodative intraocular lens (1CU AIOL).At present,few studies on the effect of PCO and Nd∶ YAG laser capsulotomy on intraocular shifting of 1CU AIOL are published.Objective The present study was to evaluate the effect of PCO and Nd∶YAG laser capsulotomy on the shifting of 1CU AIOL.Methods A respective serial caseobservational study was designed.Written informed consent was obtained from each patient prior to this study.Twentyfour eyes of 20 patients with PCO after phacoemulsification and implantation of 1CU AIOL were included in this study.Ocular examination was performed 3 months after IOL implantation,1 day before Nd:YAG laser capsulotomy and 3 months after Nd∶YAG laser capsulotomy to evaluate the distance corrected near visual acuity(DCNVA).The difference in the anterior chamber depths before and after administering 1％ pilocarpine topical eye drops was measured with the IOLMaster to determine the intraocular shifts of the IOL.The extent of IOL shifting was compared among 3 time points to assess the factors influencing IOL accommodation after 1CU AIOL implantation.Results The shifting amplitude of 1CU AIOL was(0.44±0.21)mm 3 months after implantation of 1CU AIOL,(0.27±0.11)mm 1 day before Nd ∶ YAG laser capsulotomy,and (0.34±0.10) mm 3 months after Nd ∶ YAG laser capsulotomy,showing a significant difference among them(F=7.180,P=0.001).The shifting amplitude of 1CU AIOL significantly declined 1 day before Nd∶YAG laser capsulotomy in comparison with 3 months after implantation of 1 CU AIOL(P =0.006).The shifting amplitude 3 months after Nd∶YAG laser capsulotomy increased slightly in comparison with 1 day before Nd∶YAG laser capsulotomy(P=0.059).DCNVA was(3.1±0.9)J 3 months after implantation of 1CU AIOL,(6.2±0.8) J 1 day before Nd ∶ YAG laser capsulotomy and(3.4±0.7) J 3 months after Nd ∶ YAG laser capsulotomy,with a significant difference among them (F =110.270,P =0.000).DCNVA was lower 1 day before Nd∶ YAG laser capsulotomy than 3 months after implantation of 1CU AIOL(P＜0.05).However,DCNVA was higher 3 months after Nd∶YAG laser capsulotomy than that of 1 day before Nd∶YAG laser capsulotomy (P＜0.05).There was no significant correlations between DCNVA and IOL movement 3 months after IOL implantation,1 day before Nd∶ YAG laser capsulotomy and 3 months after Nd ∶ YAG laser capsulotomy (r1 =-0.150,P1 =0.486,r2 =-0.320,P2 =0.122,r3 =-0.100,P3 =0.633).Conclusions The shifting amplitude of 1CU AIOL markedly declines due to PCO.No clinically significant influence of Nd ∶ YAG laser capsulotomy on the shifting amplitude of 1 CU AIOL is found.DCNVA can improve after Nd∶YAG laser capsulotomy.Multiple inter-related factors concerning pseudophakic accommodation may influence DCNVA.

Hypertension is one of main risk factors for the occurrence and death of stroke and coronary heart disease. Its prevalence rate is rising year by year. It severely threatens the health of the human beings. The acupuncture method of "activating blood and dispersing wind, harmonizing Gan-Pi" for treating hypertension launched by Academician SHI Xue-min has aroused great attention due to good cur- ative effect and less adverse reactions. In this paper principles of the circular motion covered by the acupuncture method of "activating blood and dispersing wind, harmonizing Gan-Pi" were clarified.

Objective To evaluate the effect of remote limb ischemic postconditioning on the level of adiponectin during myocardial ischemia-reperfusion (I/R) in rats.Methods Fifty-seven male Sprague-Dawley rats,aged 8 weeks,weighing 250-350 g,were randomly divided into 3 groups (n =19 each):sham operation group (group S); group I/R; remote limb ischemic postconditioning group (group RLIP).Myocardial ischemia was induced by occlusion of anterior descending branch of left coronary artery for 30 min followed by 180 min reperfusion in urethane-anesthetized rats.In group S,the anterior descending branch was only exposed but not ligated.The animals underwent 10 min ischemia of bilateral hind limbs starting from 20 min of occlusion of the anterior descending branch,followed by reperfusion in RLIP group.The changes in S-T segment were recorded at 30,60,120 and 180 min of reperfusion.At 180 min of reperfusion,the blood samples were taken from the jugular vein for determination of serum levels of creatine kinase MB (CK-MB) and cardiac troponin Ⅰ (cTnⅠ).The animals were then sacrificed and hearts were removed for measurement of myocardial infarct size (IS) and adiponectin contents in myocardial tissues (by ELISA).Results Compared with group S,S-T segment was significantly elevated at each time point,myocardial IS,and serum cTnⅠ and CK-MB levels were increased,and adiponectin contents were decreased in I/R and RLIP groups.Compared with group I/R,elevation of S-T segment was significantly decreased at each time point,myocardial IS,and serum cTnⅠ and CK-MB levels were decreased,and adiponectin contents were increased in RLIP group.Conclusion The mechanism by which remote limb ischemic postconditioning reduces myocardial I/R injury is related to increased level of adiponectin in the myocardium of rats.

Objective To investigate the inhibitory effect of 5-fluorouracil (5-FU) on hepatocellular carcinoma (HCC) cell growth and to elucidate its potential molecular mechanism.Methods Real-time PCR analysis was conducted to determine the expression of miR-373 in HCC tissue specimens and HCC cell lines.The expression of miR-373 was also evaluated in HepG2 cells after 5-FU treatment.Western blot analysis was performed to detect the protein levels of PPP6C,a verified target of miR-373,with transfection of miR-373 mimics or 5-FU treatment.A rescue assay was conducted to investigate the cell growth in HepG2 cells by using CCK-8.Results miR-373 expression was up-regulated in both HCC tissues and cell lines.miR-373 expression depicted about 2.94-fold augment in HepG2 cells as compared to normal liver cells control (P ＜0.01).5-FU treatment led to a significant decrease of miR-373 levels (approximately 50％,P ＜0.01,48 h) and resulted in a marked increase of PPP6C protein (approximately 2.1-fold,48 h) in HepG2 cells.The overexpression of miR-373 could prevent the impact of 5-FU treatment on cell growth in HepG2 cells and CCK-8 assay showed that HepG2 cell growth was rescued approximately 81％ and 84％ at 24 h (P ＜ 0.05) and 48 h (P ＜ 0.01),respectively.Conclusion 5-FU can repress endogenous miR-373 level,which activates the expression of downstream targeted gene PPP6C,thereby exerting an inhibitory effect on HepG2 cells.

Objectives To investigate the effects of lipoxin receptor agonist BML-111 on IFN-βand IE86 mRNA expression of macrophages infected by human cytomegalovirus (HCMV). Methods Macrophages were infected with HCMV (MOI=0.5), and the cultured cells were randomly divided into control group, HCMV group, HCMV+BML-111 group, and HCMV+MP group. The cells were collected at 0,1,2,4,8 and 12 h after infection, and the levels of IFN-βand IE86 mRNA were tested by real-time PCR. Results Compared with HCMV group, the levels of IFN-βmRNA in HCMV+BML-111 group increased significantly (P < 0.05), while the levels of IFN-βmRNA in HCMV+MP group decreased significantly (P < 0.05); Compared with HCMV group, there were no significant differences of the levels of IE86 mRNA in HCMV+BML-111 group (P>0.05), while the levels of IE86 mRNA in HCMV+MP group increased significantly (P < 0.05). Conclusion BML-111 exerts antiviral activity by promoting the expression of IFN-βmRNA at the early stage of HCMV infection.
