RESUMO
Objective: To analyze the reasons that restrict the growth of cataract surgery service capacity in public hospitals in Shanghai in recent years. Methods: The status of surgeries performed in public hospitals are analyzed based on the data related to cataract surgery collected from the database of Shanghai Eye Disease Treatment. Meanwhile, the surgeries performed by ophthalmologists working in the public hospitals are studied based on the National ophthalmology service capacity questionnaire. Results: The cataract surgery volume performed in public hospitals of Shanghai increased from 45 480 in 2013 to 51 941 in 2015. In 2014, the year on year growth rate of cataract surgery volume in tertiary hospitals was 8.54%, while in 2015, it was -0.21% on an annual basis. More than 70% cataract surgeries were performed in tertiary public hospitals. For those performed in tertiary public hospitals, 80% were performed in urban area. The actual surgeons in tertiary account for 70% of the actual surgeons in all public hospitals. Among all cataract surgeries performed in secondary hospitals, half were performed in urban areas. The volume of cataract surgery by cataract surgeon and the number of the ophthalmologist were higher than those in secondary hospitals. The average cataract surgery volume of tertiary hospitals in urban areas and the average annual cataract surgery volume of the actual surgeons are much higher than those of the secondary hospitals in the urban areas, but it is contrary in exurban areas. Conclusion: The excessive density of tertiary hospitals in urban area and poor ophthalmology service capacity in secondary hospitals in suburban and exurban areas have restricted the rapid growth rate of cataract surgery and even a decline in Shanghai public hospitals.

Objective: To analyze the changes of cataract surgery volume and related influencing factors in Shanghai during 2013 and 2015. Methods: The information of Cataract patients during the period of 2013 and 2015 was collected from Shanghai Cataract Operations Database. The cataract surgery volume and CSR of Shanghai residents and non-registered ones were compared. The cataract surgery volume and CSR of registered Shanghai residents in urban, suburban and exurban areas were calculated, respectively. In addition, the sources of surgery cost, hospitals where surgeries were performed were analyzed. Results: In Shanghai, the cataract surgery volume grew from 63 915 to 114 688 and the total CSR grow from 2 686 to 4 729 during the years between 2013 and 2015. In this period, the cataract surgery volume of registered Shanghai residents in urban, suburban and exurban areas increased from 27 203, 21 921, 8 847 to 46 415, 40 463, 18 171, respectively. The CSR1 (CSR of registered Shanghai residents) grew rapidly from 4 081 to 7 363, while the CSR2 (CSR of non-registered Shanghai residents) grew slowly from 619 to 949. According to statistics, 93.08% of the registered Shanghai residents paid the medical expenses with their medical insurance, while more than 80% non-registered Shanghai residents afforded it at their own expenses. The number of total CSR in urban, suburban and exurban areas increased from 5 085, 3 600, 3 205 to 3 600, 6 588, 6 513 respectively. In 2015, the number of cataract surgery cases in non-public hospitals exceeded that in public hospital, accounting for 54.71% of the total cataract surgeries. In the same year, 55.44% of the total cases come from suburban and exurban residents. Conclusions: From 2013 to 2015, there had been a dramatic increase in cataract surgery volume in nonpublic hospitals and exurban area in Shanghai, which effectively solved the problem of low CSR in suburban and exurban area, however the 1ow level of CSR of non-registered Shanghai residents was the key factor that significantly reduced the total CSR in Shanghai.

Surgical treatment of cataract is the emphasis of prevention of blindness in China. In the past ten years, cataract prevention work has made great strides. However, the cataract surgery rate (CSR) in one million people is still far away from the developed countries, and not enough to eliminate the blindness of cataract in our country. The CSR is related to many factors. In this article, the issue of the CSR increase is commented from four aspects, including improving the quantity and quality of cataract surgery, increasing the allocation of ophthalmic resources to primary hospitals, strengthening the cooperation between the urban and backward areas in ophthalmology, and the economic factors. It is hoped that our ophthalmic practitioners pay more attention to the prevention of blindness, and the quantity and quality of cataract surgery could be increased.

In China, the number of diabetic retinopathy (DR) patients is increasing rapidly. Prevention is the most effective method to reduce blindness and visual impairment caused by DR. The ophthalmic professionals who are interested in the DR prevention and treatment should promptly go to the communities, work together with general practitioners and community health personnel, make full use of community residents health archives, and gradually establish community DR screening protocols. Thus the efficiency of screening and early intervention of DR will be improved, and finally the high incidence and high prevalence of blindness related to DR will be controlled.

Lipopolysaccharide (LPS)-induced endotoxemia triggers the secretion of proinflammatory cytokines and can cause acute lung injury (ALI). The high mobility group box 1 (HMGB1) protein plays an important role as a late mediator of sepsis and ALI. Galantamine (GAL) is a central acetylcholinesterase inhibitor that inhibits the expression of HMGB1. This study evaluated the effects of GAL by measuring levels of inflammatory mediators and observing histopathological features associated with LPS-induced ALI. Sixty 8-10 week old male Sprague-Dawley rats (200-240 g) were randomized into three groups as follows: control group, LPS group (7.5 mg/kg LPS), and LPS+GAL group (5 mg/kg GAL before LPS administration). Histopathological examination of lung specimens obtained 12 h after LPS administration was performed to analyze changes in wet-to-dry (W/D) weight ratio, myeloperoxidase (MPO) activity, and HMGB1 expression level. Additionally, plasma concentrations of tumor necrosis factor-α, interleukin-6, and HMGB1 were measured using an enzyme-linked immunosorbent assay at 0 (baseline), 3, 6, 9, and 12 h after LPS administration. Mortality in the three groups was recorded at 72 h. LPS-induced ALI was characterized by distortion of pulmonary architecture and elevation of MPO activity, W/D weight ratio, and levels of pro-inflammatory cytokines, including tumor necrosis factor-α, interleukin-6, and HMGB1. Pretreatment with GAL significantly reduced the LPS-induced lung pathological changes, W/D weight ratio, levels of pro-inflammatory cytokines and MPO activity (ANOVA). Moreover, GAL treatment significantly decreased the mortality rate (ANOVA). In conclusion, we demonstrated that GAL exerted a protective effect on LPS-induced ALI in rats.
