? AlM: To analyze the reason of corneal epithelial implantation and ingrowth after laser in situ keratomileusis ( LASlK ) , and summarize the treatment experiences.
?METHODS: The clinical data of postoperative corneal epithelial ingrowth on 18 cases (30 eyes) from 1 256 cases (2 256 eyes) after LASlK were retrospectively analyzed in our hospital from January 2008 to December 2012. After the treatment of all eyes, patients’ general visual quality scores before and after treatment were analyzed.
?RESULTS:There were 18 cases ( 30 eyes ) with corneal epithelial implantation and ingrowth after LASlK, and the incidence rate was 1. 3%. ln the 18 cases (30 eyes), there were 12 eyes corneal flap epithelial ingrowth caused by postoperative trauma, 12 eyes caused by multiple corneal flap flush, 2 eyes caused by intraoperative irregular corneal flap, and nothing special for 4 eyes. The classification of corneal epithelial ingrowth of 30 eyes:grade I, 11 cases (18 eyes);gradeII, 4 cases (8 eyes);grade Ⅲ, 3 cases ( 4 eyes ) . Grade I-II were treated with TobraDex eye drops and intraocular pressure lowering drug. Grade Ⅲ firstly were treated by drugs, otherwise by surgery if it didn’t improve. After treatment, 8 cases (13 eyes) epithelial ingrowth disappeared from 11 cases ( 18 eyes ) , 3 cases ( 5 eyes ) implanted epithelial tumor shrank in grade l;epithelial implantation of 2 cases (4 eyes) in grade II disappeared, implantation degree of 2 cases (4 eyes) reduced to grade I;2 cases (2 eyes) in grade Ⅲ had 0. 5 ~ 1mm wide flap edge shallow gray ribbon 1 mm inside the limbus, visual acuity was 0. 8 ~1. 2, 1 case ( 2 eyes ) treated with curettage corneal epithelial implantation and endophytic epithelium hadn’t relapsed in the follow-up. After the treatment, 18 cases of corneal epithelial ingrowth got lower visual quality scores than those before therapy (Hc=10. 511, P<0. 01).
?CONCLUSlON: Operation standardized, postoperative early detection and aggressive treatment are important for prevention and treatment of complications after LASlK.

OBJECTIVETo investigate the effect of Busheng Huoxue Capsule (BHC) on the quality of life (QOL) in senile male osteoporosis (OP) patients, and to explore its mechanisms.

METHODSTotally 200 senile primary OP patients were randomly assigned to two groups according to random digit table method, 100 in each group. Patients in the treatment group took BHC plus caltrate-D (600 mg CaCO3), while those in the control group took alendronate (70 mg per week) plus caltrate-D. The therapeutic course was 12 months for all. Chinese medical symptom score and quality of life (QUALEFFO-41) score, bone mineral density (BMD) of lumbar vertebra (L2 -L4) and left femoral neck were compared between the two groups before and after treatment. Serum free testosterone (FT) and estradiol (E2) were also measured.

RESULTSChinese medical symptom scores and QUALEFFO-41 scores, serum FT and E2 levels increased in the two groups after treatment (P < 0.05, P < 0.01). The therapeutic effect was superior in the treatment group (P < 0.05, P < 0.01). After treatment the BMD of lumbar vertebra (L2 -L4) and the left femoral neck were somewhat improved (P < 0.05), but with no statistical difference between the two groups (P > 0.05).

CONCLUSIONBHC could effectively improve the QOL of senile male OP patients, which might be correlated with elevating the BMD levels and regulating the levels of sex hormones.

AIM:To study the feasibility of recombinant adeno-associated virus(rAAV)as a vector to transfer the green fluorescent protein(GFP)gene as a target gene into rabbit retina.METHODS:Intravitreal injection of rAAV-gfp was performed in either eye for each rabbit with the other eye taken as control.At the 3rd,7th,and 14th day after injection,the eyeballs were removed,and the retinas were flat-mounted on glass slides to inspect the retinal fluorescence,respectively.RESULTS:After intravitreal injection of rAAV-gfp,the presence of fluorescent spots in the cytoplasm of retinal cells indicated that GFP gene was efficiently transferred and expressed in the rabbit retina.CONCLUSION:Recombinant adeno-associated virus is a reliable and simple vector for transferring target gene,e.g.,GFP gene,to the retina.

Objective To study the clinical features,diagnosis and treatment of eosinophilic granuloma of bone(EGB).Methods Twelve cases(8 male and 4 female)of EGB and their medical record,imaging examinations,follow-up data were reviewed,and the lesion sites,symptom and clinical features were analyzed with reference to relative literature.Results Nine unifocal cases were found in the cervical spine(3 cases),the thoracic spine(1 case),the lumber spine(1 case),the femur(1 case),the metacarpal bones(1 case),and the ilium(2 cases).Three multifocal cases were found in the thoracic and lumber spine(1 case),in the femur,the multiple ribs,the skull,the scapula(1 case)and in the skull,the femur,the ilium(1 case).The most common presenting symptom was pain at the lesion site and restricted motion was obviously in the cervical lesion.The case of the thoracic lesions was found neurologic deficit.Osteolytic destruction was found in the radiologic examination in EGB and the periosteal reaction was found in the long bone lesions,and vertebra plana was considered as typical cha-racteristics in the spine lesion.The lesions not in the spine were diagnosed by biopsy,exclusive methods and close following-up were performed in the spine lesions.Two unifocal were healed spontaneously and three were performed with curettage with one bone grafting.Multifocal and the lesions in the spine underwent chemotherapy.All cases were followed up and no recurrence was found.Conclusions EGB is commonly solitary and not seldom in the spine.Topical pain may be chief complaint.Osteolytic image was found in the radiologic examination.Biopsy and exclusive methods combining closely follow-up were used for diagnosis.EGB is self-limited observation,so curettage or chemotherapy can be used in treatment,and prognosis is good.

Objective To investigate the role of white matter astrocytes and their specific protein S100A4 in sensory neurite outgrowth in vitro.Methods White matter astrocyte cultures expressing S100A4 were prepared. Dissociated adult dorsal root ganglion(DRG)cells were placed on the top of the astrocytes and co-cultured for 6,12, 18,24 hours.Small interfering S100A4 RNA was used to eliminate S100A4 expression.The growth of DRG cell neu- rites on S100A4-sileneed and S100A4-expressing astrocytes was compared.Results 12,18 and 24 hours after the co-culture with S100A4-expressing or S100A4-silenced astroeytes,neurite growth from the DRG cells was observed. Neurite outgrowth was significantly greater in S100A4 siRNA treated cultures compared to control siRNA treated white matter astrocyte cultures.Conclusion These findings suggest that white matter astroeytes are able to support axonal regeneration and,furthermore,that administration of small interfering S100A4 RNA provides strong additional support for axon regeneration.

Objective To analyze the antimicrobial susceptibility of Mycoplasma isolates for rational antimicrobial therapy. Methods BioM?rieux IST kit was used for identification and susceptibility testing of Mycoplasma strains.Results Mycoplasma was positive in 49.5% of the specimens tested.Of the Mycoplasma detected,Ureaplasma urealyticum(Uu)alone accounted for 74.7%,Mycoplasma huminis(Mh)alone accounted for 18.1%,and Uu+Mh was identified in 7.2% of the patients.The results of antimicrobial susceptibility testing showed that the Mycoplasma isolates were most susceptible to doxycycline (98.1%).Ciprofloxacin was the least active (17.3%).Conclusions Doxyeycline,josamycin,and clarithromycin can be used in the treatment of urinary tract infections caused by Mycoplasma.

ObjectiveTo study the effects of Deanxit associated with illumination on the depressed patients with chronic pain in open psychology ward in general hospitals.Methods41 patients were assigned into two groups:study group included 21 patients,who received the treatment of Deanxit(1 mg/d),even more with the treatment of illumination;control group included 20 patients,who only received the treatment of Deanxit(1 mg/d).Assessments of the efficacy were performed with Beck depression inventory(BDI) and Hamilton depression scale(HAMD) before and in the 2nd,4th,8th week during treatment.In addition,Symptom Checklist-90(SCL-90) was also used before and after treatment,as well as six month after discharge.ResultsThe efficacy was consistent with study group's superiority versus control group.ConclusionThe treatment consisting of Deanxit associated with illumination is effective on depression and helpful to prevent relapsing.

OBJECTIVETo explore the effect of a self-made guiding needle of steel wire in guiding the wire through the tibial tunnel for the treatment of avulsion fractures of tibial posterior cruciate ligament with open reduction and wire fixation.

METHODSFrom February 2011 to June 2014, a total of 22 patients with avulsion fractures of tibial posterior cruciate ligament underwent surgical treatments were analyzed, including 14 males and 8 females with an average age of 35.6 years old (ranged, 17 to 63 years old). According to Meyers classification, 9 patients were classified as type II, 13 patients were classified as type III. All the patients underwent open reduction and wire fixation with medial knee "L" shape approach. A wire guiding needle was used to guide the wire through the tibial tunnel during operation.

RESULTSWith the assistance of wire guidance needles, wires passed through the tibial tunnel rapidly during the operation in all the 22 patients. All the patients were followed up, X-ray imagings 6 months after operation showed the fractures healed well. The average follow-up time in all patients was 6 months (ranged, 6 to 12 months). The averaged Lysholm knee score in 22 knee was 92.7 +/- 3.4. All patients' posterior drawer test were negative.

CONCLUSIONSelf-made wire guiding needle can simplify the operation procedures in which the wires pass through the tibial tunnel, shorten the operation time, reduce the surgical trauma and complications, and be worthy of clinical application.
