Background:To examine the cosmetic outcome of femtosecond laser-assisted pterygium surgery(FLAPS)with conjunctival autograft(CAG)and its potential predictive ***:This was a prospective interventional case series(NCT02866968).We included 29 patients(29 eyes)with primary pterygium who underwent *** outcome was graded by two graders(an ophthalmology resident and an experienced ophthalmologist)using Hirst classification system(1-4=excellent-poor).Weighted Cohen’s kappa analysis was performed to examine the intra-and inter-rater *** relationship between cosmetic outcome and various factors were determined by Spearman’s correlation coefficients(r).Results:The preoperative severity of pterygium(Tan grading system)was mild/atrophic(7%),moderate/intermediate(62%),and severe/fleshy(31%).An ultrathin CAG(mean thickness of 74.5±9.8μm)was fashioned *** excellent cosmetic outcome of FLAPS(median±IQR)was observed at 3 months(1.0±1.0)and remained similar at 6months(1.0±0.0)and 12months(1.0±0.0)*** final follow-up,27(93%)patients achieved good-to-excellent cosmetic outcome,with 1(3%)patient having a poor outcome due to incomplete pterygium *** kappa analysis of Hirst grading system showed excellent intra-rater(κ=0.86-0.95)and inter-rater reliability(κ=0.84-0.88).There was a weak and borderline significant correlation between good cosmetic outcome and reduced postoperative CAG thickness(r=0.38,P=0.06)but not with age,gender,preoperative pterygium severity,or intraoperative CAG ***:FLAPS can result in an excellent cosmetic outcome,which may be attributed to the beneficial effect of an ultrathin CAG.

ABSTRACT: Fulminant hepatic failure is a medical emer-gency. When this condition declared itself irreversible, atimely liver transplantation is the only effective treatment.A 34-year-old chinese with fulminant hepatic failure wasevaluated as a potential liver transplantation candidate. Onthe erect chest radiograph, chilaiditi' s sign has developedover a very short period of a week due to rapid shrinkage ofthe liver. Awareness of chilaiditi' s sign facilitated distin-guishing the condition of free gas under the diaphragm dueto bowel perforation and subphrenic abscess by gas formingmicro-organisms. Rapidity of onset of this sign parallels thedeterioration of liver function and reflects the urgency ofcondition.

1 I had lived at Shuiguo Lake in Wuhan for several years, when one day a wasp flew on my balcony. I was sitting there, reading my newspaper. Because I had been stung by wasps many times during my childhood, I had a lingering fear of wasps. I hurried to cover my face with the newspaper, but the wasp flew’ unharmed onto my bonsai. I looked at it quietly and it also looked at me. Then it stuck up its tail and lowered its head to drink from the pot. Once

OBJECTIVE： To investigate the effects of transcutaneous electrical nerve stimulation （TENS） through acupoints on the intraocular pressure （lOP） in patients with glaucoma. METHODS： A single-blinded, randomized experimental design study was conducted. Patients from the North of Taipei Ophthalmology outpatient department diagnosed with intraocular hypertension were selected and were further enrolled if they met the research subject criteria. The patients who met all criteria, and who met no exclusion criteria became the participants. Participants were randomly assigned into the treated group, wherein the TENS electrodes （Qing Ming Medical Device Co., Ltd., New Taipei City, china） were applied with direct current （DC） on the acupoints Pucan （BL 61） and Shenmai （BL 62） for 20 min. The control group received no TENS electrode treatments. Measurements of lOP were taken four times using a pneumotonometer （Clinico Co., Ltd., New Taipei City, china）, before, immediately after, 30 min after, and 60 min after TENS electrode treatments. RESULTS： Eighty-two participants completed the experiment, lOP decreased more in the group treated with DC （P 〈 0.01） than in the control *** lOPs were not affected by the age of the patients and their usage of medications. CONCLUSION： TENS of acupoints of Pucan （BL 61） and Shenmai （BL 62） could significantly reduce the lOP in patients with glaucoma.

The production of chemicals from lignocellulosic biomass provides opportunities to synthesize chemicals with new functionalities and grow a more sustainable chemical industry. However, new challenges emerge as research transitions from petrochemistry to biorenewable chemistry. Compared to petrochemisty, the selective conversion of biomass-derived carbohydrates requires most catalytic reactions to take place at low temperatures (< 300 °C) and in the condensed phase to prevent reactants and products from degrading. The stability of heterogeneous catalysts in liquid water above the normal boiling point represents one of the major challenges to overcome. Herein, we review some of the latest advances in the field with an emphasis on the role of carbon materials and carbon nanohybrids in addressing this challenge.

A redundant-subspace-weighting(RSW)-based approach is proposed to enhance the frequency stability on a time scale of a clock *** this method,multiple overlapping subspaces are constructed in the clock ensemble,and the weight of each clock in this ensemble is defined by using the spatial covariance *** superimposition average of covariances in different subspaces reduces the correlations between clocks in the same laboratory to some *** optimizing the parameters of this weighting procedure,the frequency stabilities of virtual clock ensembles are significantly improved in most cases.
