·AIM:To observe the efficacy and the safety of low-dose mitomycin-C (MMC) in the treatment of pterygium.·METHODS:In a prospective,randomized and controlled clinical trial,a total of 550 eyes of 400 patients diagnosed with pterygium were randomly divided into the four groups-group 1:130 eyes of 100 patients,without MMC;group 2:140 eyes of 100 patients,with 0.2g/L MMC;group 3:150 eyes of 100 patients,with 0.3g/L MMC;group 4:130 eyes of 100 patients,with 0.4g/L MMC.They underwent the excision of primary pterygium barely the sclera.Visual acuity,intraocular pressure (IOP),extraocular movement,iridocyclitis,scarring, symptoms (tearing,photophobia,foreign body sensation) and signs (conjun-ctival hyperemia,ulcer of sclera and cornea,perforation of sclera) of subjects,were recorded on the day of enrollment,and after the surgery,on 2 weeks,2 months,6 months,and 1 year.·RESULTS:In group 3 and group 4,the recurrence of pterygium after the excision were less than that in group 1 and group 2 ( P < 0.01 ).In group 4,after the surgery,there were more probability of raising lOP,iridocyclitis,symptoms and signs than that in group 1,2,and 3.·CONCLUSION:Low-dose MMC is effective in the treatment of preventing the recurrence of primary pterygium.Its efficacy rises along with its density.And meantime,the safety of the treatment of low-dose MMC declines.

Objective To investigate the clinical effects of focused ultrasound in the treatment of cervical erosion.Methods 417 patients with cervical erosion were treated with focused ultrasound(Haijixing treatment instrument),and followed up for 3 months to observe the efficacy and adverse reactions.Results In total 417 cases,321cases(76.98％) were cured,and there were effective in 95 cases(22.78％),ineffective in 1 case(0.24％),and the total effective rate was 99.76％.No serious adverse reactions were founded.Conclusion Focused ultrasound(Haijixing treatment instrument) in the treatment of cervical erosion has obvious effect and mild adverse reactions.

005) The prevalence of Hp infection in antrum was significantly lower in patients with GERD (16/50) and BE (33/106) than that in control subjects (30/50,P

The prevalence of age-related macular degeneration (AMD) is increasing yearly,and AMD has become the first cause of elderly vision irreversible loss.In China,an aging society is developing,so the prevention and therapy for AMD is faced with a new challenge.Thc multi-faceted study on AMD has become a focus of fundus disease in ophthalmology.AMD is thought to be a multifactorial-induced disease,and it is closely related to age,genetic and environmental factors.But its pathogenesis is not understood enough up to now.In recent years,epidemiological study revealed that the chromosome 10q26 has multiple polymorphic loci.Age-related maculopathy susceptibility 2 ( ARMS2,rs10490924 ) is reported to be a major risk factor of AMD in the yellow race.In this paper,the ARMS2 gene epidemiology,cell positioning and related treatment were reviewed.

· AlM: To analyze the clinical data of 54 cases misdiagnosed as optic neuritis and to explore measures to reduce misdiagnosis
· METHODS: This retrospective study comprised 54 patients that had been misdiagnosed as optic neuritis from September 2000 to June 2013. The misdiagnosis features were summarized.
· RESULTS:Many diseases can easily be misdiagnosed as optic neuritis, including ischemic optic neuropathy, intracranial tumors, optic nerve vasculitis, myelinated nerve fibers, and so on.
· CONCLUSlON: The measures to reduce misdiagnosis consisted of detailed history collection, perfect physical examination and comprehensive expertise of fundus disease.

Objective:To investigate the effects of the treatment of early cracked teeth with vital pulp preservation.Methods:63 early cracked teeth with vital pulp in 56 patients were treated by light cured composite resin filling with or without MTA rebasing,and restored by precious metal crown.The patients were followed up for 2 years.Results:After 2 years follow-up,57 teeth were successfully treated and failure was found in 6 teeth,the effective rate was 90.4％.Conclusion:Light cured resin filling directly or with MTA rebasing for early cracked teeth with vital pulp,and restoration by precious metal crown are effective in the treatment of early cracked teeth with vital pulp.

The theory framework of "cognition- emotion-behavior" of the Gestalt Psychology is based on to build the conceptual model to integrate service encounter quality, customer consumption emotion and customer satisfaction. Such a model is also used to raise related hypothesis and verified against the backdrop of the medical service industry. Empirical outcomes prove the following: hospital service encounter quality consists such factors as environment dominance, doctor dominance and nurse dominance; in the course of their consumption in hospitals, patients undergo at the same time positive consumption emotion and negative consumption emotion, as the latter exerts negative impacts on the positive one; hospital service encounter quality bears significant impact on both patient' s consumption emotion and patient satisfaction; positive emotion and negative emotion both bear significant impacts on patient' s satisfaction.

BACKGROUND:Traditional treatment of tibia and fibula fractures complicated with skin soft tissue defect is mainly external fixation, wound debridement and dressing plus skin graft or skin flap transplantation after the infection is control ed and granulation grow. This method is disadvantageous due to high cost, great pain, long hospitalization stay, infection and necrosis, even the possibility of amputation.
OBJECTIVE:To explore the clinical efficacy of vacuum sealing drainage (VSD) and external fixator in the treatment of tibia and fibula open fractmes complicated with skin defects.
METHODS:A total of 38 patients with severe open fractures of tibia and fibula complicated with skin defects were selected from Benxi Central Hospital between January 2009 and September 2013. The size of skin defects was more than 5 cm2. After external fixation, the patients underwent complete debridement and dressing, fol owed by VSD treatment for 5-7 days. After granulation tissue grew and the wound became fresh, the patients received intermedite thickness skin graft. And 15 cases treated without VSD were retrospectively selected, serving as control group. The infection control rate and wound healing time in the two groups were compared.
RESULTS AND CONCLUSION:After 5-7 days of VSD treatment, VSD dressings were removed, wound infection was control ed, local wound granulation tissue was fresh. Both the wound and fractures were healed wel , no osteomyelitis or amputation occurred. Among the involved 38 patients, 23 cases were cured, 12 cases were effective, and three cases were ineffective. The total effective rate showed significant differences compared with the control group (92%vs. 53%;P<0.05). VSD can completely remove the wound secretions and necrotic tissue, improve local microcirculation, eliminate the infection, VSD plus external fixator and skin grating is a simple and effective method in treatment of tibia and fibula open fractures with soft tissue defects.

Objective To investigate the family caregivers of patients with indwelling catheter care behavior .By analyzed its in‐fluencing factors to help caregivers improve the quality of life for patients .Methods Convenience sampling method by visit 70 pri‐mary caregivers of family indwelling catheter for the patient′s .They were investigated with gathering general information and Gen‐eral Self‐Efficacy Scale(GSES) ,following with caregivers awareness questionnaire indwelling catheter .Indwelling catheter care be‐havior questionnaire survey analyze behavior and other items to take care of the relationship .Results The general self‐efficacy and caregiver indwelling catheter cognition ,which account for 73 .9% of the total variance of caring behaviors ,were the important fac‐tors affecting care behaviors .Conclusion There is a big shortage in indwelling catheter home care caregiver knowledge and care be‐haviors .According to above professionals can provide targeted guidance for caregivers .
