AIM: To observe the clinical effect of phacoemulsification and posterior chamber intraocular lens ( IOL) implantation in the treatment of unilateral high myopia combined with age-related cataract.
METHODS: A retrospective clinical study was carried out in a single ophthalmology center. All patients diagnosed of unilateral high myopia with age- related cataract were performed phacoemulsification and posterior chamber IOL implantation. The axial length of operation eye was ≥27mm, and the axial length of unoperated fellow eye was≤25mm. Visual acuity and complications were followed up for 1, 7d, 1, 3mo postoperative.
RESULTS:Thirty-three patients with average age 68. 8±9. 26 (41-87) y were enrolled in this study, 7 cases were men, 26 cases were women. The mean axial length of operation eyes was 29. 44±1. 80(27. 1-32. 71) mm and the mean axial length of unoperated fellow eyes was 23. 39±0.92 ( 21. 72 - 24. 90 ) mm. The average axial length difference of binocular eyes was 6. 06±1. 97(2. 78-9. 92) mm. The best corrected visual acuity ( BCVA ) increased from 0. 02±0. 02(light perception~0. 12) preoperatively to 0. 20±0. 20 ( 0. 02 - 0. 8 ) at 3mo postoperatively. There was statistically significant difference (t= -5. 278, P<0. 05). Among the 10 patients whose axial length difference of binocular eyes was 2. 01 - 5. 00mm, 60% of their postoperative BCVA were >0. 3. Among the 13 patients with binocular axial length difference of 5. 01-7. 00mm, 46.2% of BCVA were >0. 3,46.2% achieved 0. 05-0. 25. Another 10 patients of binocular axial length difference between 7. 01-9. 99mm, 90% of BCVA were <0. 3, of which 40% were<0. 05. No complications occurred during operative and postoperative .
CONCLUSION: Phacoemulsification and posterior chamber IOL implantation can effectively improve the postoperative visual acuity and it is safe for unilateral high myopic patients combined with age-related cataract. The recovery of visual acuity is related with binocular axial length difference.

Scar formation, also known as tissue fibrosis, is a common response when most organs of the body get pathological damage.The cell populations involved are as follows: circulating fibroblasts from bone marrow, endothelial cells, resident fibroblasts, epithelial cells, and perivascular cells(pericytes).Pericytes are a kind of vascular wall cells, surrounding endothelial cells on the side of basement membrane in the microvascular system.It plays an important role in angiogenesis, maintaining the blood-brain barrier, regulating function of capillary blood, mediating the entry of immune cells into the brain, fibrosis response and so on.There is accumulating evidence suggests that pericytes are involved in the scar formation of central nervous system.This article reviews the scar formation process of central nervous system diseases such as spinal cord injury, epilepsy and traumatic brain injury, with emphasis on the role of pericytes in scar formation of central nervous system.On this basis, the perspective of pericytes involved in the regulation of scar formation is given.

Objective To learn the effect of individualized nutritional support in the treatment of severe acute pancreatitis and provide an effective nutritional support therapy for the disease.Methods 97 patients of severe acute pancreatitis were randomly divided into 51 cases of observation group and 46 cases of control group.The control group was given standard parenteral nutrition.The observation group was given the same heat and support stage of individual nutrition nitrogen.Hemoglobin (Hb),albumin (ALB),pre albumin (PA)and transferrin (TFN)of the two groups were detected before and after treatment.The recovery time of serum amylase,resumed oral intake time, hospitalization time and hospitalization expenses of the two groups were observed.The occurrence of gastrointestinal complications was observed in the two groups during the treatment period.Results Compared with before treatment, after treatment Hb,ALB,PA,TFN of the two groups were significantly increased (t =4.114,7.540,5.556,8.307 and 1.994,3.970,2.906,5.099,all P <0.05).After treatment,ALB,PA,TFN of the observation group were higher than the control group (t =2.249,2.256,3.630,all P <0.05).After treatment,recovery time of serum amylase,resumed oral intake time,hospitalization time and hospitalization expenses of the observation group were lower than the control group (t =3.191,5.245,4.846,8.762,all P <0.05).The incidence rate of gastrointestinal complications of the observation group was 11.8%(6 /51),and that of the control group was 15.2%(7 /46),the difference was not statis-tically significant (χ2 =0.248,P >0.05).Conclusion In the treatment of severe acute pancreatitis,individualized nutritional support has better curative effect,low incidence of complications,with good clinical application value.

Objective To investigate the relationship between helicobacter pylori(Hp) infection and Henoch-Schonlein purpura(HSP) in children and find out the etiological treatment for HSP.Methods Positive rate of Hp-IgG between normal children and children with HSP were compared.Infection of Hp was detected by rapid urease test,and relationship between infection of Hp and clinical symptom in Henoch purpura was analyzed.Children with HSP were randomly divided into two groups and were respectively treated with Hp eradication therapy together with conventional therapy and conventional therapy only.The recurrence rates were compared.Results The infection rate in 150 children with HSP,especially the 90 children with Henoch purpura was significantly higher than that in normal children,and it was in positive correlation with abdominal symptom.Hp infection with triplex therapy for 2 weeks in HSP could reduce the recurrence of HSP.Conclusions Hp infection may be one of the reasons of HSP in children,and is related with Henoch purpura.Eradication of Hp can reduce recurrence of HSP.

To assess the postoperative outcomes of piggyback implantation using Acrysof Toric intraocular lens ( lOL ) in high myopia combined with corneal astigmatism.
●METHODS: Sixty patients who had phacoemulsification with lOL implantation due to high myopia, cataract and corneal astigmatism from January 2010 to June 2013 were randomly divided into observation group (piggyback Toric lOL implantation, both an Acrysoft lQ Toric lOL and a minus foldable acrylic three piece lOL were implanted in the capsular bag, n= 30) and control group (foldable lOL implantation, n = 30). Postoperative follow - up went on 6mo. lnformation collected included uncorrected visual acuity ( UCVA), lOL position, residual astigmatism and complications.
● RESULTS: The UCVA increased from 3. 52 ± 0. 03 preoperatively to 4. 78±0. 01 at 6mo postoperatively in the observation group, from 3. 51±0. 03 preoperatively to 4. 30± 0. 13 at 6mo postoperatively in the control group. The observation group's postoperative UCVA was better than that of the control group. There was statistically significant difference ( t = 3. 612, P < 0. 05 ). The preoperative corneal astigmatism was 2. 97 ± 0. 87 (1. 70 -4. 27) D in the observation group and 2. 92 ± 0. 97 (1. 50 -4. 90)D in the control group. The postoperative residual astigmatism was 0. 48 ± 0. 23 ( 0. 25 - 1. 00 ) D in the observation group and 2. 87 ± 1. 11 (1. 00 - 5. 20) D in the control group. There was statistically significant difference postoperatively (t = - 11. 995, P < 0. 05) between the two groups. No complications occurred.
●CONCLUSlON: Piggyback implantation using Toric lOL can help to solve the problem of no matching Toric lOL power for the high myopia combined with corneal astigmatism at the current stage. lt improves the UCVA and reduces the astigmatism after the cataract surgery.

The herpes simplex virus type 1 (HSV-1) infected-cell protein 27 (ICP27) is an essential,highly conserved protein involved in various steps of HSV-1 gene regulation as well as in the shut-off of host gene expression during infection.It functions primarily at the post-transcriptional level in inhibiting precursor mRNA splicing and in promoting nuclear export of viral transcripts.Recently,many novel functions performed by the HSV-1 ICP27 protein were shown,including leptomycin B resistance,inhibition of the type I interferon signaling,regulation of the viral mRNA translation and determining the composition of HSV-1 virions.

As one of the immediate-early(IE)proteins of herpes simplex virus type 1(HSV-1),ICP22 is a multifunctional viral regulator that localizes in the nucleus of infected cells.It is required in experimental animal systems and some nonhuman cell lines,but not in Vero or HEp-2 cells.ICP22 is extensively phosphorylated by viral and cellular kinases and nucleotidylylated by casein kinase Ⅱ.It has been shown to be required for efficient expression of early(E)genes and a subset of late(L)genes.ICP22,in conjunction with the UL13 kinase,mediates the phosphorylation of RNA polymerase Ⅱ.Both ICP22 and UL13 are required for the activation of ode2,the degradation of cyclins A and B and the acquisition of a new cdc2 partner,the UL42 DNA polymerase processivity factor.The cdc2-UL42 complex mediates postranscriptional modification of topoisomerase Ⅱa in an ICP22-dependent manner to promote L gene expression.In addition,ICP22 interacts with cdk9 in a Us3 kinase dependent fashion to phosphorylate RNA polymerase Ⅱ.

OBJECTIVE:To optimize the inclusion technology of Eugenol-β-cyclodextrin (β-CD) inclusion complex,and to identify and characterize it. METHODS:With the molar ratio of eugenol to β-CD,inclusion temperature and inclusion time as fac-tors,using the yield of inclusion compounds as index,the inclusion technology was optimized by orthogonal test. The formation of inclusion compound was identified by the spectra change of FT-IR,XRD and 1H NMR. Its structure was characterized by 1H RO-ESY NMR. RESULTS:The optimized inclusion conditions were that the molar ratio of eugenol to β-CD was 1.0:1;inclusion tem-perature was 60 ℃;inclusion time was 2.0 h. And the yield of inclusion compound was 73.86%(RSD=0.17%,n=3). 1H NMR results ofβ-CD and its inclusion complex indicated that the optimum qualitative ratio of the inclusion complex was 1.0:1. The inter-molecular interaction between eugenol and β-CD was confirmed by the spectrum analysis of FT-IR and XRD. 1H ROESY NMR re-sults indicated the structure of inclusion complex mainly was that the phenyl of eugenol was in the cavity of β-CD,the vinyl was outside. CONCLUSIONS:The inclusion technology is reasonable and feasible,and can be used for the inclusion of eugenol andβ-CD. The formation of inclusion compound is confirmed by the spectrum analysis.
