AIM: To evaluate the efficacy of implantable collamer lens (ICL)-V4c implantation in the correction for high myopia. METHODS: This retrospective analysis collected twenty-five patients (43 eyes) with high myopia treated with ICL/TICL implantation from September to December 2016 at Department of Ophthalmology, West China Hospital. Routine ophthalmic examinations were performed. The patients were followed 3mo to monitor uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), refractive error, intraocular pressure, corneal endothelial cell count, contrast sensitivity and scores for Quality of Life lmpact of Refractive Correction Questionnaire ( QIRC ). Statistical analyses were performed using repeated measures ANOVA, LSD-t test and paired-samples T test. RESULTS: Postoperative UCVA and BCVA were significantly higher than before surgery (all P<0. 01). Postoperative spherical mirrors at all time points were lower than before surgery(all P<0.01),and there was no significant difference between the different time point postoperative (all P>0. 05). The safety index in 3mo postoperatively was 1.38士0.24 and the effective index was 1. 22士0. 15. There was no statistical difference in intraocular pressure between preoperative and postoperative time points (F=1.464, P=0.215). There was no statistical difference in endothelial cell density at 3mo after surgery compared to preoperative (t=-0.544, P= 0. 586). The postoperative Log contrast sensitivity (LogCS) of 12.0 cycles per degree (c/d) and 18.0 c/d were significantly higher compared to the preoperative (F=4.347, P=0.010; F=4.539, P=0.005; respectively), but other (the postoperative LogCS of 3.0 c/d and 6.0 c/d) differences were statistically insignificant (F=1.094, P=0.354;F=1 325,P=0.271;respectively). There was no significant difference in the amount of change in the QIRC scores between preoperative and postoperative(F=2.669, P=0 094). CONCLUSION: ICL V4c implantation is a safe and effective method for the correction of high myopia.

Objective To explore related factors of amputation in patients with diabetes foot ulcer(DFU) and provide the evidence of reducing amputation rate.Methods A total of 307 inpatients with DFU in this hospital from October 2013 to December 2015 were collected and divided into amputation group(n=28) and non-amputation group(n=279).The clinical data and laboratory data were treated with single variable analysis and multivariate Logistic regression analysis.Results Single variable analysis showed that hospitalization time,hyper-sensitive C-reactive(hs-CRP) and fibrinogen(FIB) level were significantly increased in amputation group(P＜0.05) when compared with non-amputation group,and the hemoglobin (Hb) level,high-density lipoprotein cholesterol(HDL) and serum albumin (ALB) level in amputation group were markedly lower than in non-amputation group(P＜0.05).Amputation rate was significantly different among different Wagner grades (P=0.000).Multivariate Logistic regression analysis showed that hospitalization time,Wagner grade were independent risk factors of amputation in patients with DFU,OR values were 1.024(95％CI:1.009-1.039) and 2.779 (95％CI:1.753-4.404),respectively.While HDL was a protective factor of amputation in patient with DFU (OR=0.161;95％CI:0.036-0.729).Conclusion The higher the rank of Wanger in DFU patients are,the longer hospital stay and the higher amputation risk become.HDL is the protective factor of DFU amputation.

Objective To explore the effects and action mechanism of miR-181c-5p on biological behaviors of pros-tate cancer cells.Methods The pathological relationship between BIRC5,miR-181c-5p and prostate cancer was analyzed based on prostate cancer data in TCGA database.The target binding site of miR-181c-5p and BIRC5 was analyzed by miRNA target gene prediction database,and was verified by double luciferase activity assay.The ex-pression of BIRC5 protein in miR-181 c-5p overexpression cells was detected by Western blot.The prostate cancer cells PC3 and DU145 were selected to construct cell line with miR-181c-5p overexpression(miR-181c-5p group)and its negative control(miR-NC group),and qRT-PCR verification was conducted.The cells proliferation[opti-cal density at 450 nm site(OD450 nm)]was detected by CCK-8.Distribution of cell cycles and apoptosis rate were detected by flow cytometry.Expressions of proliferation and apoptosis related proteins were detected by Western blot.The cell line with miR-181c-5p/BIRC5 overexpression was constructed(miR-181c-5p+BIRC5 group).Cells growth,distribution of cell cycles,apoptosis rate and expressions of related proteins were detected by the a-bove methods.Results The expression of BIRC5 was up-regulated in prostate cancer tissues,and it was higher in patients with high tumor invasion,lymph node metastasis and recurrence.Patients exhibiting high expression of BIRC5 demonstrated poor survival rates.The expression of miR-181c-5p was down-regulated in prostate cancer tis-sues.The level of miR-181c-5p was negatively correlated with BIRC5 level,and miR-181c-5p could inhibit BIRC5 expression.In PC3 and DU145,miR-181c-5p level in miR-181c-5p group was higher than that in miR-NC group(P＜0.05);OD450 nm and percentage of S-phase cells were lower than those in miR-NC group(P＜0.05),per-centage of cells in G0/G1 phase;apoptosis rate and expressions of BAX,caspase-3 and PARP proteins were higher than those in miR-NC group(P＜0.05);expressions of CDK2,CCNB1 and BCL-2 proteins were lower than those in miR-NC group(P＜0.05).The expression of BIRC5 protein and OD450 nm in miR-181 c-5p+BIRC5 group were higher than those in miR-181c-5p group(P＜0.05),percentage of cells in G0/G1 phase was lower than that in miR-181c-5p group(P＜0.05);percentage of S-phase cells was higher than that in miR-181c-5p group(P＜0.05);apoptosis rate was lower than that in miR-181c-5p group(P＜0.05);expressions of CDK2,CCNB1 and BCL-2 proteins were higher than those in miR-181c-5p group;expressions of BAX,caspase-3 and PARP proteins were lower than those in miR-181 c-5p group.Conclusion miR-181-5p can inhibit the proliferation of human pros-tate cancer cells by targeting BIRC5,block cells in G0/G,phase and promote cells apoptosis.

Alagille syndrome (ALGS) is an autosomal dominant disorder which is mainly caused by JAG1 gene mutation and can affect multiple systems including the liver, heart, eyes, skeleton and face. This paper reports the clinical and genetic features of an ALGS patient. A 2-year-and-9-month-old boy was referred to the hospital with the complaint of abnormal liver function and heart murmur discovered over two years. Jaundice of the skin and sclera was not observed. The child had a prominent forehead, left esotropia, depressed nasal bridge and micromandible. The two lungs were clear on auscultation, but a systolic cardiac murmur of grade 2/6 could be heard between the 2nd and 3rd intercostal space at the left sternal border. Neither abdominal distension nor enlarged liver or spleen was discovered. X-ray radiography uncovered butterfly malformation of the 6th and 8th thoracic vertebrae. Serum biochemistry analysis revealed elevation of total bile acids, bilirubin and transaminases. Based on the clinical characteristics and the consultation opinion of the ophthalmologist, the child was diagnosed to have ALGS with Duane retraction syndrome. DNA direct sequencing detected a novel JAG1 mutation c.2419delG(p.Glu807AsnfsX819) in the child. Symptomatic and supportive therapy was performed thereafter and clinical follow-up was conducted until he was 4 years and 2 months. In the follow-up visits, his general condition remained stable, but the facial malformations, left esotropia, cardiac murmur and abnormal liver function persistend. The long-term outcome needed to be observed.

Alagille syndrome (ALGS) is an autosomal dominant disease affecting multiple systems including the liver, heart, skeleton, eyes, kidneys and face. This paper reports the clinical and genetic features of an infant with this disease. A 3-month-and-10-day-old female infant was referred to the hospital with jaundiced skin and sclera for 3 months. Physical examination revealed wide forehead and micromandible. A systolic murmur of grade 3-4/6 was heard between the 2th and 3th intercostal spaces on the left side of the sternum. The abdomen was distended, and the liver palpable 3 cm under the right subcostal margin with a medium texture. Serum biochemistry analysis revealed abnormal liver function indices, with markedly elevated bilirubin (predominantly direct bilirubin), total bile acids (TBA) and gamma-glutamyl transpeptidase (GGT). Atrial septal defect and pulmonary stenosis were detected on echocardiography. Next generation sequencing detected entire deletion of the JAG1 gene, and then chromosomal microarray analysis revealed a novel interstitial deletion of 3.0 Mb in size on chr20p12.3p12.2, involving JAG1 gene. The child had special facial features, heart malformations, and cholestasis, and based on the genetic findings, ALGS was definitively diagnosed. Thereafter, symptomatic and supportive treatment was introduced. Thus far, the infant had been followed up till his age of 11 months. The hyperbilirubinemia got improved, but GGT and TBA were persistently elevated, and the long-term outcome needs to be observed. This study extended the JAG1 mutation spectrum, and provided laboratory evidences for the diagnosis and treatment of the patient, and for the genetic counseling and prenatal diagnosis in the family.
