To evaluate the clinical efficacy of corneal lamellar debridement combined with sutureless amniotic membrane transplantation for the treatment of superficial fungal keratitis.
●METHODS:Totally 22 cases (22 eyes) with superficial fungal keratitis were referred to our hospital from April 2012 to October 2013. The patients with persistent cornea ulcer after treatment of local and systemic antifungal drugs underwent corneal lamellar debridement combined with sutureless amniotic membrane transplantation, and the recipient bed was covered with an amniotic membrane using fibrin sealant during the operation. All patients were still given topical antifungal therapy for 1 -2mo after operation. The followed- up time was 3mo or above. We observed the corneal healing and amniotic membrane adhesion by split lamp microscope, and investigated the transformation of amniotic membrane and fungal infection recurrence with confocal microscope.
●RESULTS: Corneal edema and anterior chamber reaction of 21 patients disappeared gradually, and no amniotic membrane graft dissolved and shed off within 1-2wk postoperatively. Two weeks after operation, the graft integrated into the corneal and the corneal wounds' thickness increased gradually, the corneal epithelium reconstructed and corneas became clear. Four weeks after operation, the corneal scarring developed gradually and fluorescence staining was negative. Nineteen cases' amniotic membranes that adhered with the cornea dissolved 4wk after operation. There were different degrees of corneal nebula or macula remained 3mo postoperatively. All patients' vision improved in varying degrees, except in 1 case with fungal keratitis who had been cured by lamellar keratoplasty.
●CONCLUSlON:Corneal lamellar debridement combined with sutureless amniotic membrane transplantation can effectively remove the foci of inflammation, improve the local efficacy, shorten the operation time, relieve the postoperative reaction, and promote cornea union, which is an effective way to treat superficial fungal keratitis.

AlM: To compare the clinical efficacy of treatment on recurrent pterygium using different concentration mitomycin C ( MMC) in the pterygium excision operation combined with the corneal limbal stem cell autografting ( CLSCA) .METHODS: Sixty patients ( 65 eyes ) with recurrent pterygium were randomly divided into three groups. All cases were accepted CLSCA, 21 patients (22 eyes) were given 0. 15g/L MMC during operation, 20 patients ( 22 eyes) were given 0. 25g/L MMC during operation, 19 patients ( 21 eyes ) were given 0. 4g/L MMC during operation. The patients were followed up for 6mo to 2a.RESULTS:The recurrent rates of the three groups were 9%, 5%, 5% respectively. There was no statistically significant differences (P>0. 05). The complication rates of the three groups were 5%, 36%, 33% respectively. There were statistically significant differences (P<0. 05). CONCLUSlON: The treatment to the recurrent pterygium using low concentration MMC has the similar recurrence rates, but the complication rate was lower, it is an ideal operation method, and it is worth popularization and application.

BACKGROUND:Hydrophilic acrylic materials with good biocompatibility have been widely used in clinic. However, there are some problems about the biocompatibility and safety of hydrophilic acrylic intraocular lens after long-term clinical application. OBJECTIVE:To discuss the biocompatibility and stability issues and corresponding processing methods after hydrophilic acrylic intraocular lens implantation. METHODS:A computer-based search of Wanfang and PubMed database was performed for articles related to clinical application of hydrophilic acrylic intraocular lens published from 2005 to 2014. The keywords were “hydrophilic acrylic,intraocular lens” in Chinese and English, respectively. A total of 618 articles were initialy retrieved, and finaly 35 articles were included in result analysis. RESULTS AND CONCLUSION:As the hydrophilic acrylic intraocular lens is foldable, a smal incision is required for implantation and the operation is simple that cause less damage to the patients. In addition, the hydrophilic acrylic intraocular lens has poor bacterial and inflammatory cel adhesion, which leads to a low probability of infective endophthalmitis after implantation. But there is a high incidence of posterior capsule opacification as wel as some refractive errors and visual quality problems after implantation. Taken together, to solve these problems depends on the continuous improvements and updates of intraocular lens materials and designs.

OBJECTIVE: To evaluate the relative bioavailibility and bioequivalence of paroxetine hydrochloride film-coated tablets. METHODS: In a randomized crossover study, 24 healthy Chinese male subjects received a single oral dose (20 mg) of either test or reference paroxetine hydrochloride tablets after an overnight fast. The plasma concentrations of paroxetine were determined by a validated LC-MS/MS method. The pharmacokinetic parameters, the relative bioavailability and bioequivalence of two formulations were evaluated by DAS 2.0 software. RESULTS: After a single oral dose of 20 mg test or reference paroxetine tablets, the pharmacokinetic parameters of paroxetine were as follows: ρmax(5.102 ± 2.955) and (5.396 ± 2.852) μg · L-1; tmax (5.22 ± 1.83) and (5.35 ± 0.78) h; t1/2(11.76 ± 2.91) and (11.98 ± 3.57) h; AUC0~96h(118.1 ± 90.2) and (118.9 ± 86.0) μg · h · L-1; AUC0-∞ (120.2 ± 91.0) and (121.5 ± 87.6) μg · h · L-1, respectively. CONCLUSION: The relative bioavailability of the test paroxetine hydrochloride film-coated tablets is (100.6 ± 22.0)%. The two preparations are bioequivalent.

Objective To investigate the protective effect and mechanism of betaxolol on optic nerves after experimental retinal ischemia-reperfused injury. Methods Retinal ischemia was induced in SD rats by increasing intraocular pressure through intracameral infusion. Sixty-eight rats were randomly divided into 3 groups: normal control (eight rats), 0.25% betaxolol treatment (thirty rats) and saline control group (thirty rats). The latter two groups were subdivided into group 1 day, 3 and 7 days after reperfusion, respectively, with 10 rats in each group. Betaxolol and normal saline was applied to the right eyes of the rats in the treatment group and to the ones in normal saline control group, respectively. The amplitude of b-wave of electron retinograph (ERG) was observed and the histological and ultrastructural changes were detected by light and electron microscopy. The expression of neural nitrogen oxide synthase (nNOS) was detected by immunohistochemistry. The content of malonyldialdehyde (MDA) and the superoxide dismutase (SOD) activity were measured by spectrophotometer. Results [WTBZ]Began from the first day after reperfusion, in saline control group, the amplitudes of ERG b-wave reduced continuously, the histopathological damages of retina were aggravating, the expression of nNOS increased, MDA level increased and SOD level decreased persistently, which significantly differed from the normal control group (P0.01). Conclusion Betaxolol, by reducing intracellular overfreight of Ca~(2+),inhibiting production of NO and elevating the ability of anti-oxidation in rat retina, can protect retinal neurons from ischemia-reperfused injury.

In order to promote the Shenqifuzheng injection (SQFZ) clinical medication safety, this study reevaluate on SQFZ post marketing safety study systematically. Including multi center large sample registration type safety monitoring research, the analysis based on national spontaneous reporting system data, the analysis based on the 20 national hospital information system data and literature research. Above the analysis, it suggests that SQFZ has good security. The more adverse drug reaction (ADR) as allergic reactions, mainly involved in the damage of skin, appendages and its systemic damage, serious person can appear allergic shock. ADR/E is more common in the elderly, may be related to medication (tumor) populations. Early warning analysis based on SRS data and literature research are of the view that "phlebitis" has a strong association with SQFZ used.
