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.

Objective To study the influence of vascular endothelial growth factor(VEGF) on development of alveolar epithelial cell Ⅱ (AECⅡ) and expression of pulmonary surfactant protein B(SP-B) in premature rats.Methods Wistar rats at 19 days gestation were paunched to get embryo and primary AECⅡculture.The rats were divided into 4 groups ,VEGF-165 group,Dexamethasone group,VEGF and Dexamethason group,control group. AECⅡ and SP-B expression were measured by immunology histochemistry.Results SP-B had positive expression in VEGF group, Dexamethason group, VEGF and Dexamethason group. SP-B had negative expression in control group.Conclusion VEGF-165 can increase SP-B positive expression and secret of AECⅡ.VEGF promotes lung maturity.

Secondary metabolites are the result of that plant interaction with biological and non-biological factors in the long-term evolution process, and play an important role in plant growth, development and physiology. The effective components of medicinal plant are usually the secondary metabolites in plant cells, and the synthesis of them are affected by a variety of factors, such as environmental impact. Acquirement of the secondary metabolites via callus culture has the advantage of low cost and less environmental impact. The synthesis and accumulation of medicinal plant secondary metabolites are not only controlled by light, temperature and pH, but also infected by germplasm, plant growth regulator and elicitor. This article presents a review of the influencing factors, and provides a basis for further study and development.

Objective To study the effects of vascular endothelial growth factor(VEGF)on production of pulmonary surfactants.Method Fetal rat lungs were obtained at 19-day gestation.Primary culture of typeⅡalveolar epithelial cells(AECⅡ)was performed using IgG panning technique.The rats was divided into groups: VEGF,Dexamethasone,VEGF plus Dexamethasone and a control.Total phospholipids,phosphatidylcholine (PC),phosphatidyl glycerol(PG)and sphingornyelin(SM)were determined.Results expressed as mean?SEM. Comparison between groups were made with LSD-t test and one -way ANOVA.Result VEGF,Dexamethasone and VEGF plus Dexamethasone groups showed increased amount of total phospholipids and its compositions on the first day of culture.Conclusions VEGF-165 promotes the production and secretion of pulmonary surfactant. VEGF and Dexamethason may go through different mechanism for enhancement of synthesis of pulmonary surfactant,thereby improve biological function of AECⅡ.

Objective: To observe the difference in clinical efficacy between acupuncture with point selection based on syndrome differentiation along the meridians and acupuncture at non-meridian and non-acupoint points for functional dyspepsia (FD). Methods: A total of 74 FD patients were randomized into an observation group and a control group, with 37 cases in each group. Both groups received acupuncture treatment. Zusanli (ST 36) and Neiguan (PC 6) were selected in the observation group, with Taichong (LR 3) and Neiting (ST 44) added for excess syndrome, and Gongsun (SP 4) and Yinlingquan (SP 9) added for deficiency syndrome. Four non-meridian and non-acupoint points were selected in the control group. The treatments in both groups were performed once a day with a 2-day break after 5 consecutive treatments, which constituted one treatment course. A total of 4 courses were performed. The scores of Nepean dyspepsia index (NDI) and Leeds dyspepsia questionnaire (LDQ) were recorded before and after treatment, and during follow-up (8, 12, 16, 20 and 24 weeks after recruitment) to assess the clinical efficacy. Results: The NDI scores in the two groups after treatment and at each time point during follow-up were higher than those before treatment (all P<0.05), and the LDQ scores were lower than those before treatment (all P<0.05). The NDI scores after treatment and at each time point during follow-up in the observation group were higher than those in the control group (all P<0.01); the total LDQ score and scores of upper abdominal pain, postprandial satiety and upper abdominal burning sensation after treatment and at each time point during follow-up in the observation group were significantly lower than those in the control group (P<0.01 or P<0.05).. Conclusion: Acupuncture with point selection based on syndrome differentiation along the meridians has a better curative effect than acupuncture at non meridian and non-acupoint points in the treatment of FD.

Objective To investigate homografting vascular endothelial progenitor cells(EPCs)for preventing restenosis formation of carotid artery in New Zealand white rabbit models.Methods EPCs of New Zealand white rabbits were isolated,confirmed and expanded though the injured carotid arterial endothelium of rabbit model induced by dilatation with a 2.5 F balloon;and then EPCs were transplanted into the injured endothelium of the cells transplantation group(n=13,3 of them were transplanted with fluorencently-labeled- EPCs),while equal volume of saline without EPCs was injected into the injured endothelium in the control group(n=8).Histopathology was performed at 4 days after transplantation for the 2 rabbits,with fluorencently-labeled-EPCs.All of the rest remained rabbits were killed 4 weeks later for histological examinations.Results The histopathological slides showed that the fluorescence-positive expression existed in the injured endothelium 4 days after transplantation.At 4 weeks after the EPCs transplantation,there were less restenosis and less vascular wall thickening in the rabbits of cells transplantation group than those of the control group(P＜0.01).Conclusion The local interventional homografting heterogeneous endothelial progenitor cells can prevent restenosis after the carotid artery angioplasty in New Zealand White rabbit model.

AIMTo observe the expression of Urotensin II (U II) and its receptor (UT) on right ventricle in rats with chronic pulmonary hypertension induced by hypoxia and hypercapnia.

METHODSTwenty male SD rats were randomly divided into normal control group (NC) and hypoxia-hypercapnia 4-week group(HH). Mean pulmonary arterial pressure(MPAP) and the weight ratio of right ventricle (RV) to left ventricle plus septum (LV+ S) were calculated separately. U II in plasma was measured using radioimmunoassay. The expression of U II was observed in right ventricle myocytes and right ventricle arteries by immunohistochemistry. The expression of U II mRNA and UT mRNA were observed in right ventricle myocytes and right ventricle arteries by in situ hybridization.

RESULTS(1) The MPAP and RV/LV + S of HH group were higher respectively than those of NC group (P < 0.01, respectively). (2) The plasma U II content of HH group did not increased obviously than that of NC group. (3) The expression score of U II, U II mRNA, UT mRNA by right ventricle myocytes in HH group were higher significantly than those of NC group (P < 0.01 respectively). (4) The average value of integral light density (LD) of U II, U II mRNA, UT mRNA by right cardial arteries in HH group were higher significantly than those of NC group (P < 0.01, respectively).

CONCLUSIONThe expression of U II in right ventricle arteries and right ventricle myocytes increase significantly during the formation of pulmonary hypertension and right ventricle hypertrophy in rats chronically exposed to hypoxia-hypercapnia. These changes indicate that U II might be involved in right ventricle remodeling, which promotes proliferation of cardiac muscle cells.

OBJECTIVETo investigate the possible association between the SNP in the 5' untranslated region (5' UTR) of the human beta defensin 1 (DEFB1) gene and the susceptibility to pulmonary tuberculosis (PTB) in Chinese Han population.

METHODSIn this case-control study, venous blood was collected from 102 patients with PTB and 148 healthful persons. Genomic DNA was extracted using whole blood DNA extraction kit. The -52A/G, -44C/G and -20A/G SNP were genotyped by PCR-directed sequencing. The genotypes and allele frequency were analyzed using the χ(2) test. The linkage disequilibrium and haplotype were analyzed by SHEsis software.

RESULTSA total of 102 patients with PTB (69 males and 33 females, (53.42 ± 20.22) years old) and 148 healthy control cases (95 males and 53 females, (50.67 ± 14.53) years old) were enrolled, with no difference in gender and age (all P values > 0.05). DEFB1 -44 CC genotype was significantly more frequently found in PTB patients than in control group (81.4% (83/102) vs 66.9% (99/148), χ(2) = 5.114, P < 0.05, OR = 2.096, 95%CI: 1.095 - 4.011), so was -44C allele (89.2% (182/204) vs 80.4% (238/296), χ(2) = 6.975, P < 0.05, OR = 1.576, 95%CI: 1.086 - 2.286). No difference in -52 A/G and -20 A/G SNP was observed between the two groups. The proportion of the GGG (-52/-44/-20) haplotype was lower in PTB patients than in the control group (0.030 vs 0.081, χ(2) = 5.629, P < 0.05, OR = 0.348, 95%CI: 0.140 - 0.863). No linkage disequilibrium was found among the SNP of the three sites (D' values were 0.132, 0.064, 0.088; r(2) values were 0.003, 0.002, 0.003; all P values > 0.05).

CONCLUSIONThese results suggest that the SNP of DEFB1 5' UTR is associated with susceptibility to PTB in Chinese Han population. -44 C→G SNP and the related haplotype (GGG) might play a protective role in the pathogenesis of PTB.
