Objective:To evaluate the effect of anti-vascular endothelial growth factor (VEGF) in patients with wet age-related macular degeneration (wAMD) and investigate the recurrence factors.Methods:In this case-control study, 40 eyes of 38 patients with wAMD treated by anti-VEGF therapy in Xijing Hospital from October 2015 to April 2017 were included.Ranibizumab or conbercept was consecutively intravitreally injected monthly under 3+ pro re nata (PRN) regimen.All included patients were followed-up at least 12 months.The best corrected visual acuity (BCVA) was expressed in logarithm of the minimum angle of resolution (LogMAR) units.Optical coherence tomography (OCT) was used to observe the morphologic characteristics of macula and measure the central retina thickness (CRT). Patients were divided into recurrence and recurrence-free group based on whether recurrence occurred during follow-up.Potential associated factors with recurrence after treatment were analyzed by multivariate logistic regression analysis.Meanwhile, the morphological and functional response were identified at 1 month after loading phase as well as at last follow-up visit.This study protocol was approved by the Ethics Committee of Shanghai General Hospital (No.2016KY243) and written informed consent was obtained from each patient prior to receiving injection.Results:All the operative eyes showed retinal effusion absorption at least once, and 21 (52.5%) eyes had relapse during follow-up.The patients with lower BCVA (LogMAR) value at the first absorption time had higher risk of recurrence ( OR=16.7, 95% CI=1.22-100, P<0.05). The eyes in the recurrence group received more times of treatment than eyes in the recurrence-free group (5.8±2.3 vs 3.5±1.4, t=3.64, P<0.05). However, there was no significance between the two groups in BCVA change before and after treatment ( t=-1.52, P>0.05). In the recurrence group, the BCVA (LogMAR) and CRT at last visit were 0.73±0.34 and (187.2±81.7)μm respectively, while were significantly improved in comparison with 0.81±0.37 and (234.2±74.5)μm at the relapse time ( t=2.14, 2.62; both at P<0.05). There were 87.5% (35/40) eyes showed good morphological responses at 1 month after the loading phase while 12.5% (5/40) eyes presented poor morphological responses, the retinal effusion was absorbed after additional (3.2±2.2) times of injections.The BCVA of eyes with a good morphological response at 1 month following loading phase was better than that at the first retinal effusion absorption time ( t=-2.23, P<0.05). Average CRT at last visit was significantly decreased in comparison with the baseline CRT ( Z=-4.62, P<0.01). Conclusions:For wet AMD patients, the anti-VEGF treatment is safe and effective in the short term, while there is still a high rate of recurrence.More attention should be paid to eyes with better vision at the first time of retinal effusion absorption which may have more chance to experience recurrence.Patients need long-term follow-up after treatment to prevent recurrence.In addition, the complete loading treatment is needed for patients who have a good morphological response after the first retinal effusion absorbed.

Objective:
To observe and explore the therapeutic efficacy of hyperbaric oxygen (HBO) in the treatment of non-arteritic anterior ischemic optic neuropathy (NAION).
Methods:
A total of 139 NAION patients were randomly divided into a control group of 72 and a hyperbaric oxygen group of 67. Both groups were given conventional drugs including prednisolone, mecobalamin and compound anisodine, while the hyperbaric oxygen group was additionally provided with hyperbaric oxygen treatment at a pressure of 0.2MPa once a day for 30 days. Each day′s treatment lasted for 110 minutes, including 20 minutes at increasing pressure, 20 minutes decreasing and 60 minutes with the pressure stable at 0.2MPa. Before and after the 30-day treatment, the visual acuity and visual mean sensitivity (MS) of the two groups were observed and compared.
Results:
There was no significant difference between the control group and the hyperbaric oxygen group in terms of average visual acuity or visual MS before the treatment. Afterward the average visual acuity (4.88±0.25) and visual MS (16.68±1.19) of the hyperbaric oxygen group were significantly higher than before the treatment and significantly better than those of the control group. The total effective rate of the hyperbaric oxygen group was 91%, significantly higher than that of the control group (75%).
Conclusions
Conventional treatment combined with hyperbaric oxygen therapy can significantly promote the visual acuity and visual MS of NAION patients.

Objective:
To study the prevalence and correlates of diabetes among HIV/AIDS who were on antiretroviral therapy (ART) in Dehong Dai and Jingpo autonomous prefectures (Dehong), Yunnan province.
Methods:
The database of HIV/AIDS receiving ART in Dehong was downloaded by using the basic information system of AIDS prevention and control in China. In this cross-sectional study, HIV/AIDS patients who were currently on ART and aged 18 years or above, were consecutively recruited, between July 2017 and June 2018, in Dehong. All the subjects underwent hemoglobin A1c (HbA1c) testing. Patient with diabetes was defined as meeting any of these indicators (HbA1c ≥6.5%, baseline FPG ≥7.0 mmol/L, FPG ≥7.0 mmol/L in the most recent visit). Both univariate and multivariate logistic regression analysis were carried on to evaluate the correlates of diabetes among the HIV/AIDS patients.
Results:
In total of 4 376 HIV/AIDS patients were included for analysis, with the average age as (43.7±10.1) years, proportion of males as 53.8% (2 356/4 376) and the HCV positive rate as 24.1% (1 055/4 376). The mean years was (8.9±3.8) years after the HIV diagnosis was made, and the mean duration on treatment was (6.8±2.9) years. The prevalence of diabetes was 11.4% (500/4 376). Through multivariate logistic regression analysis, data showed that the risk factors of diabetes of HIV/AIDS on ART were: aged 40 years or above, being male, HCV positive, baseline body mass index ≥24.0 kg/m2, elevated TG ≥1.70 mmol/L in the most recent visit and baseline antiretroviral regimens under Efavirenz (EFV).
Conclusions
Prevalence rate of diabetes appeared higher in HIV/AIDS patients who were on ART in Dehong. Prevention and control measures should be targeted on HIV/AIDS patients who were with risk factors of diabetes as being elderly, male, HCV positive, overweight and higher TG. Further esearch is needed to evaluate the association between the use of EFV and diabetes.
