International Eye Science 2016;16(8):1554-1556
Abstract?AIM: To investigate the risk factors and prognosis of posterior capsular rupture in phacoemulsification cataract surgery through analyzing the cataract patients in our hospital.?METHODS:Totally 1825 patients (1912 eyes) treated in our hospital were selected from November 2012 to November 2015. The patients with posterior capsular rupture were as observation group.Control group was randomly selected with a 1: 4 ratio in patients without posterior capsular rupture.All the patient's age, gender, type of cataract, ocular disease history, other medical history, surgical history, preoperative intraocular pressure, the eyes affected, the health situation, visual acuity at 1d before and after surgery and other factors were recorded and analyzed for risk factors and prognosis.?RESULTS: Statistical results showed gender, type of cataract, preoperative intraocular pressure, history of tobacco and alcohol, eyes affected and other factors did not impact on the rupture rate ( P>0.05 ); and type of nucleus, preoperative visual acuity, some eye diseases were the risk factors for posterior capsule rupture ( P<0.05).Postoperative visual acuity of the two groups was all improved, but visual acuity of patients with posterior capsule rupture significantly decreased.?CONCLUSION: With eye disease history ( a history of vitreous hemorrhage, retinal detachment before surgery and preoperative visual acuity <20/200) are more likely to result in intraoperative posterior capsular rupture.Nuclear hardness over grade Ⅳ is also an important risk factor. Before one surgery, it is needed to learn more about the medical history of cataract patients, to conduct a reasonable comprehensive assessment for risk factors, to decrease the risk in the surgery, which are to increase the success rate and to improve the prognosis.

Insulin-like growth factors (IGF), regulated by their receptors and binding proteins, play a pivotal role in human cell proliferation, differentiation and apoptosis. Increasing evidence has revealed that IGF system is involved in the genesis and progress of various malignancies including lung cancer. Recent studies in regard to IGF axis expression in the lung cancer cell lines, pulmonary tissue samples and blood circulation of lung cancer patients have shown that the IGF axis may contribute to the transformation and progression of lung cancer. Several researches have shown that a number of drugs targeting the IGF receptor are being investigated in clinical trials and suggest a potential therapeutic efficacy. This article reviews the updates and progress in the research of IGF axis in lung cancer.

OBJECTIVETo investigate the protective effects of 15-methyl-lipoxin A4 (LXA4) on mesangioproliferative nephritis in rats and the possible mechanisms.
METHODSMesangioproliferative nephritis was induced by a single intravenous injection of the mouse monoclonal anti-Thy1.1 antibodies (ER4) in 20 rats. Ten nephritic rats were injected with 15-methyl-LXA4 at 10 minutes before ER4 antibody injection and then 8-hourly until the rats were sacrificed on day 4 after nephritis induction. The nephritis was evidenced by presence of proteinuria, histologic examination with light microscopy, infiltrating leukocyte assessed by immunofluorescence microscopy, and mesangial cell proliferation assessed by proliferation scoring and by immunohistochemical staining of proliferating cell nuclear antigen (PCNA). Expressions of interleukin (IL)-1beta and IL-6 protein or mRNA in glomeruli were determined by radioimmunoassay or RT-PCR, respectively. Phosphorylated phosphoinositide 3-kinase (PI3-K), Akt1 and p27(kip1) in glomeruli were analyzed by Western Blot. Activities of nuclear factor-kappaB (NF-kappaB) and signal transducer and activator of transcription 3 (STAT3) in glomeruli were assessed by electrophoretic mobility shift assay (EMSA).
RESULTSThere were increases in glomerular infiltration of leukocyte, expressions of IL-1beta and IL-6 protein and mRNA, and activities of NF-kappaB in nephritic rats between days 1 and 4 after nephritis induction. The enhanced proteinuria, score of mesangial proliferation, glomerular PCNA positive cells, activities of phosphorylated PI3-K, Akt1 and STAT3, and reduced p27(kip1) expression were found on day 4 after nephritis induction. 15-Methyl-LXA4 treatment significantly reduced the proteinuria, glomerular infiltration of leukocyte, expressions of IL-1beta and IL-6 protein and mRNA, score of mesangial proliferation, glomerular PCNA positive cells, activities of phosphorylated PI3-K, Akt1, NF-kappaB and STAT3, and increased the p27(kip1) expression.
CONCLUSIONS15-Methyl-LXA4 can markedly inhibit the proteinuria, glomerular inflammation, and mesangial cell proliferation induced by anti-Thy1.1 antibodies. The inhibition effects are related to PI3-K/Akt1/p27(kip1)/cyclin pathway, STAT3 and NF-kappaB pathway-dependent signal transduction.

OBJECTIVETo evaluate the efficacy and safety of aripiprazole in the treatment of children with Tourette syndrome.
METHODA prospective, multi-center, controlled clinical trial was conducted in 195 children aged 5-17 years with Tourette syndrome. The patients were assigned to two groups: aripiprazole group (n=98) and tiapride group (n=97), with the treatment dosage of 5-25 mg/d and 100-500 mg/d, respectively. After 12 weeks treatment, the clinical efficacy was assessed by the Yale Global Tic Severity Scale (YGTSS) score, and adverse reactions were observed by side effects symptoms scale, blood biochemical indexes, and electrocardiography.
RESULTSignificant pre- and post-treatment differences were ascertained for motor tic, phonic tic, function damage and total scores of YGTSS in the both groups from the second week of treatment (P<0.0001). Compared with the tiapride group, the aripiprazole group showed a more significantly decreased function damage score of YGTSS by the second week of treatment (P<0.05). After 12 weeks treatment, total scores of YGTSS in the aripiprazole group decreased from 53.74±15.71 at baseline to 24.36±16.38, while in the tiapride group from 51.66±13.63 to 23.26±15.31. The mean reduction scores of YGTSS were 29.38 in the aripiprazole group and 28.40 in the tiapride group at the end of treatment, and the clinical response rates were 60.21% and 63.92%, respectively. There were no significant differences between the 2 groups (P>0.05). The incidence of adverse reactions was similar in the aripiprazole and tiapride groups, with 29.6% and 27.8% respectively. There were no significant differences in the incidence of adverse reactions between aripiprazole and tiapride groups and no severe adverse events were found in either group.
CONCLUSIONThe results showed that aripiprazole showed similar therapeutic effect to tiapride in treatment of children with Tourette syndrome. Aripiprazole was safe and well tolerated in Chinese population, and can be considered as a new valid option for the treatment of tic disorders.

OBJECTIVETo observe the influence on prognosis and possible side-effects of arginine in
METHODSMulti-center clinical trial, randomized double blinded patients with severe trauma and burns. and placebo control methods were employed in the study. Eighty-six patients with severe trauma and burns were randomly divided into control (C, n = 45) and arginine treatment (Arg, n = 41) groups. The patients in Arg group received arginine in dose of 0. 4 g x kg(-1) x d(-1) orally, while those in C group received same dose of placebo (tyrosine) for 7 days. All the patients in both groups were given diet with equal calories and equal nitrogen content. The changes in the wound healing time, hospital stay, and the incidence of side-effects of the medication in both groups of patients were observed and compared before and after the supplementation of arginine.
RESULTSThe wound healing time and hospital stay days of severe trauma patient in Arg group (n = 29) were 11. 1+/-2. 8 d and 19+/-6 d, which were all obviously shorter than those in C group (13. 2+/-5. 5 d, 22 +/-6 d, n =33, P <0.05). On the other hand, in severe burn patients there were no significant difference of the wound healing time (20+/-5 d vs 22+/-8 d, n = 12, P > 0. 05) and hospital stay days (28+/-6 d vs 29+/-8 d, n = 12, P >0. 05) between the Arg and C groups. In addition, in C and Arg groups, the occurrence of the side-effects were seldom (2. 44% vs 2. 22% , P = 1. 000) and it disappeared when the supplementation of drugs was stopped.
CONCLUSIONOral feeding of arginine is beneficial in enhancing wound healing, reduction of hospital stay days in severe trauma patients and with little side-effects, but it is not beneficial to improve the prognosis of severe burn patients. Maybe this is due to inadequate number of case involved in the study.
