International Eye Science 2016;16(11):2154-2156
AIM:To analyze the 34 cases of patients with diagnosis of lacrimal duct disease, to explore the cause and clinical characteristics of lacrimal duct inflammation, and to study the common misdiagnosis to improve the diagnosis rate, to provide clinical experience for medical workers.
METHODS: A total of 34 eyes of 34 patients were selected from 2011-06 to 2015-06 to our hospital for lacrimal duct incision. Clinical data of patients including age and gender distribution, eye and lesion location, duration, canaliculitis clinical symptoms and previous misdiagnosis were collected. The operation of lacrimal duct was carried out, and the secretion of lacrimal secretion was checked.
RESULTS:Patients over the age of 40 accounted for 77%of the population, men accounted for 23. 5%, women accounted for 76. 5%. Left eye in 15 cases, right eye in 19 cases, and were monocular onset, 26 cases ( 76%) of patients with lower lacrimal duct inflammation. Clinical symptoms: increased secretion, canthal conjunctival congestion, swelling, lesion location around the lacrimal puncta swelling and tenderness, slightly raised, epiphora, foreign body sensation. The culture results Showed 34 cases of discharge inspection. A total of 20 cases were fungal growth, 6 cases of bacterial growth rate were 59%, 18%, and 8 cases were not detected, 10 cases of lacrimal duct stone were found by pathological examination. There were 3 cases of Aspergillus, 5 cases of Candida, 2 cases of actinomycetes, 4 cases found in Gram staining microscope. Misdiagnosis of canaliculitis for other eye diseases, including 12 cases of chronic dacryocystitis, 8 cases of chronic conjunctivitis, 6 cases of acute conjunctivitis, stye in 4 cases, the misdiagnosis rate reached 88%.
CONCLUSION:In the middle and old aged people, the lacrimal duct is more than that of the male. The main pathogenic bacteria causing lacrimal duct infection may be fungi, which can be treated with anti-fungal drugs. For the removal of the lacrimal duct stone, we should distinguish the types of pathogenic bacteria for the treatment of the disease. In the case of misdiagnosis, the clinical manifestations of different clinical manifestations from the lacrimal duct infection and other diseases of the eye should be carefully examined and carefully treated.

?AIM: To study correcting effect and visual quality after laser - assisted in situ keratomileusis ( LASIK ) with femtosecond and posterior chamber intraocular lens ( ICL) implantation in high myopia patients.?METHODS: Fifty-five patients ( 106 eyes ) with high myopia from February 2012 to February 2015 in our hospital were analyzed. According to the different operation, patients were divided into the observation group( using ICL implantation, 27 cases with 53 eyes) and the control group (using LASIK, 28 cases with 53 eyes). Postoperative follow-up was 1a, to observe and analyze the visual quality, higher order aberration and complications of two groups.?RESULTS: Uncorrected visual acuity ( UCVA ) , the best corrected visual acuity ( BCVA ) , effectiveness index and security index at 1a postoperatively of observation group, were 1. 04±0. 86(LogMAR), 0. 97±0. 19(LogMAR), 104. 69± 18. 56, 108. 79 ± 17. 68, significantly higher than those of control group 0. 78 ± 0. 11 ( LogMAR ), 1. 04 ± 0. 09 (LogMAR), 93.78±15. 65, 100. 71±11. 68 (P<0. 05). And observation group in the two kinds of light and shade environment at various spatial frequency contrast sensitivity were higher than the control group. Those under the light environment at 1. 5, 3, 6, 12 c/d and under dark environment at 1. 5, 3, 6, 18 c/d compared were different between the two groups (P<0. 05). Spherical aberration and comatic aberration of observation group at 1a after operation were lower than those of control group (P<0. 05 ). The difference of trefoil between the two groups was not significant ( P > 0. 05 ). No severe complications were observed in both groups.?CONCLUSION: LASIK with femtosecond and ICL lens implantation can effectively improve the patient’s visual quality, but for patients with high myopia, ICL lens implantation effect is more significant, the safety index of ICL implantation, as well as the effectiveness index and the visual quality are better than those of LASIK.

OBJECTIVETo observe differences of therapeutic effects among acupuncture bloodletting, penicillin and acupuncture bloodletting combined with penicillin for children acute tonsillitis and providea better treatment method in cli nic.
METHODSSeventy-five mild cases were selected into section of mild symptoms while seventy-five severe cases were selected into section of severe symptoms. Cases in the two sections then were divided into, an acupuncture bloodletting group, a penicillin group and a comprehensive group by random digital table method separately, 25 cases in each one. Qu-chi (LI 11), Hegu (LI 4), Dazhui (GV 14), Shaoshang (LU 11) and Erjian (EX 11) were selected in the acupuncture bloodletting group, intravenous injection of penicillin sodium was applied in the penicillin group and acupuncture bloodletting combined with penicillin was applied in the comprehensive group. Efficacy assessment was conducted after 3 days in the section of mild symptoms and after 5 days in the section of severe symptoms.
RESULTSFor the section of mild symptoms, the total effective rate was 96.0% (24/25) in the comprehensive group and 92.0% (23/25) in the acupuncture bloodletting group, which were both superior to 68. 0% (17/25) in the penicillin group (P<0.05), but no statistical significance was seen between the comprehensive group and acupuncture bloodletting group (P>0.05). For the section of severe symptoms, the total effective rate was 96.0% (24/25) in the comprehensive group, which was obviously superior to 60.0% (15/25) in the acupuncture bloodletting group (P<0.01) and 68.0% (17/25) in the penicillin group (P<0. 05), and no statistical significance was seen between the acupuncture bloodletting group and penicillin group (P>0.05).
CONCLUSIONThe efficacy of acupuncture bloodletting combined with penicillin is little different from that of acupuncture bloodletting for treatment of children acute tonsillitis with mild accompanied symptoms, which were both superior to intravenous injection of penicillin sodium. For severe accompanied symptoms, the efficacy of acupuncture bloodletting combined with penicillin is obviously superior to acupuncture bloodletting and penicillin.

AIM :To investigate the association of primary open-glaucoma (POAG), intraocular pressure (IOP) and systemic blood pressure in a rural population aged 50 years old or above in Shaanxi Province, China.METHODS: In the population-based, cross-sectional study, 1 775 (83.53%) residents, aged 50 years old or above, from 3 counties of Shaanxi Province, China, undertook an interview with a standard questionnaire and a detailed eye examination, including logarithm of the minimum angle of resolution visual acuity, slit-lamp biomicroscopy, applanation tonometry and dilated fundus examination. Two blood pressure reading in the sitting position were taken. Gonioscopy was performed if a narrower peripheral anterior chamber (less than one fourth of the corneal thickness) was indicated. Automated visual field testing was performed by participants assessed to have suspicion of glaucomatous disc damage or if IOP was 22mmHg or higher.RESULTS: IOP significantly correlated with systemic blood pressure, and both IOP and systolic blood pressure increased significantly with increasing age. No association between POAG and hypertension was found. The frequency of POAG increased significantly with lower diastolic perfusion pressure.CONCLUSION: Data in our study are accordance with those reported in other population-based studies, and confirm that lower diastolic perfusion pressure is a significant risk factor for primary open angle glaucoma.

AIM: To assess the prevalence and risk factors for age-related macular degeneration (AMD) in a rural population in Shaanxi Province of China.METHODS: A total of 2 835 (81.00%) people aged 40 years old or more, from Fuping county, Jingbian county and Yang county of Shaanxi Province, China, underwent a comprehensive interview and a relative eye examination. The present of AMD was classified into neovascular AMD (NV) and pure geographic atrophy (GA) by using direct ophthalmoscopy for fundus examination according to International Classification System.RESULTS: The prevalence (95% CI) of AMD was 3.00% (2.42, 3.71) in this population, of which NV accounted for 1.45% (1.05, 1.98) and 1.55% (1.14, 2.10)for GA. The prevalence of AMD increased significantly with increasing age (P <0.001). AMD was present in 0.47% of participants aged 40 to 49 years, rising to 11.90% of participants older than 80 years, of which the corresponding data increased from 0.28% to 4.76% for NV and from 0.19% to 7.14% for GA. No significant difference was found in the prevalence of NA and GA between genders in this population. With multiple logistic analyses, apart from advancing age, only smoking was found to have a strong association with any type of AMD.CONCLUSION: The prevalence of AMD in the rural population of Shaanxi Province of China is lower than that reported from other population-based studies in different provinces of China, less than that reported in whites, more than that reported in blacks. Except increasing age, smoking is also a significant well-known risk factor for AMD.

· AIM: To assess the prevalence and related risk factors for primary angle-closure glaucoma in a rural population for 40 years of age or older in Shaanxi Province.· METHODS: By using a stratified, cluster-based, random sampling technique, 8 500 persons of all ages were selected randomly, including 3 500 those aged 40 years or more, from the North, the South and the Middle of Shaanxi Province in Western China from July to December in 2003. All participants had an interview with a standard questionnaire and those questions related to glaucoma of previous diagnosis and treatment, family history and outbreak history. Then a detailed and relative eye examination was performed, including logarithm of the minimum angle of resolution visual acuity, external eye examination with slit-lamp biomicroscopy and fundus examination. The intraocular pressure was measured with Perkins applanation tonometry to those persons aged 50 years old or more and those with suspected increased IOP. A further examination was performed to those persons with suspicious glaucoma, including repeated tonometric examination, gonioscopy, dark room test, automated visual field testing, et al.·RESULTS: 6 815 of the eligible 8 500 persons of all ages were interviewed and examined from July to December in 2003, a response rate of 80.18%, including 2835 of the eligible 3 500 persons of 40 years old or more with a response rate of 81.00%. According to Van Herick method, the percentage of shallow peripheral anterior chamber was 13.6%, of which 10.4% was in grade 2, 3.0% in grade 1, and 0.2% in grade 0. In this rural population for 40 years of age or older 31 participants were found to have primary angle-closure glaucoma, with the prevalence of 1.09%. With multiple logistic analyses, the prevalence increased significantly with age (P=0.008), whereas no significant difference (Pgender=0.180, Peducation=0.199) was found in the rate with gender and education, although women and illiteracy seemed to be at increased risk of the disease (OR: 1.77, 95%CI,0.77-4.10; OR: 1.71, 95%CT, 0.76-3.87). Of 31 participants, 21 persons (67.74%) had not been previously diagnosed and treated. Of 10 participants previously diagnosed, 6 (60%) had been received peripheral iridectomy; nevertheless, no any other treatments were performed. 48.39% participants suffered from visual impairment in various degrees, of which the percentage of blindness in either eye accounted for 29.03%. Of those with primary angle-closure glaucoma, 22 persons (70.97%) were classified as having chronic from of the disease.· CONCLUSION: In this rural population in Shaanxi Province of China, the rate of occludable angles is 13.6%, more common than that reported previously in other Chinese populations. The prevalence of primary angle-closure glaucoma is close to that from other Asian populations, increasing with age. A majority of glaucoma was undiagnosed and untreated previously.

Objective To establish the reference databases for bone mineral density(BMD)in multiple skeletal regions,which would be useful for diagnosis of osteoporosis(OP)and prediction of fracture risk in adult women in Qingdao.Methods BMD was measured by dual-energy X-ray absorptiometry at skeletal regions of lumbar spine,left hip(femoral neck,Ward's triangle and greater trochanter)in 868 healthy adult women aged 25- 83 years and 191 women with fractures.BMD of skeletal regions with age-related change was found to fit in 8 kinds of regression models.Best model equations of fitting were found and the reference database was established.BMD of women with fractures was compared with the reference databases to predict the risk of fracture.Results BMD in 6 skeletal regions changed with aging and a cubic regression model was better fitted with aged-related change as compared with other regression models.The coefficients of determination(R~2)of fitting curve were 0.21?0.09 (P<0.01).The BMD reference databases of women in Qingdao were established by cubic regression equation, the peak BMD of lumbar spine and hip appeared at 25-29,and 40-44 years old groups respectively.Finally,the BMD in fracture group was significantly decreased by 1.6-2.5 s as compared with the peak BMD of health women. Conclusion The bone quantity is lost rapidly after 45 years old in women.If the BMD in women after 50 years old is decreased by 1.6-2.5 s compared with the peak BMD in the same area,the risk of fracture is increased.

OBJECTIVETo understand the situation of institutional delivery of rural pregnant women in Guangxi Autonomous Region in the period of 1998 - 2003 and to identify the determinants on institutional delivery utilization.
METHODSUsing Andersen's behavioral model as analytical framework and Guangxi databank of the 3rd National Health Service Survey as data source, we described the status of institutional delivery with the rural women having had live birth history in the period of 1998 - 2003 as subjects, while and the univariate analysis and multivariate logistic analysis were done to identify determinants of institutional delivery utilization.
RESULTSAmong a total number of 407 women with live birth history, 39.80 percent of them delivered at the health-care facilities. The rate of institutional delivery increased annually in 1998 - 2003 (P< 0.0001). The proportion of delivery in township health centers increased and the proportion of home delivery decreased by year (P< 0.0001). Results from both univariate and multivariate analysis showed that parity, education background of women, type of drinking water, time needed to get to the nearest healthcare facilities by the most convenient traffic,frequency of prenatal checkup, together with whether or not being advocated on institutional delivery etc. were determinants of delivery utilization. The OR value were 1.749 for multipara, 1.995 for those going to the nearest healthcare facilities by the most convenient traffic in less than 10 minutes, 3.011 for those drinking tap water, 5.435 for those with the education of high school, 29.149 for those with over 5 times in terms of frequency of prenatal checkup and 37.822 for those being advocated on institutional delivery.
CONCLUSIONSocio-economic situation, status of maternal health care and parity made main contribution to institutional delivery and skilled birth attendance for women in rural Guangxi.
