Methods The basic information and drug use of the personnel in an institution of the joint logistics support force during the resident training period from April to June 2020 were collected and sorted out. The drug use indicators were calculated by using the defined daily dose (DDD) as the unit, including: daily drug dose (DDDs), daily drug dose cost (DDDc), drug use intensity (DUI), drug utilization rate (DUR) and drug ranking ratio (R) were used to describe drug use characteristics. Results During the resident training period, the amount of musculoskeletal system drugs was large, and the number of users was large. The dosage of cardiovascular system drugs, digestive system drugs and hormone drugs was large, but the number of users was small. Sensory organ drugs, dermatological drugs, heat-clearing agents (Chinese patent medicine) and respiratory system drugs were small in dosages, but the number of users was large. Ranked by DDDs, the top 3 drugs with the highest dosage were Yunnan Baiyao plaster, Yunnan Baiyao Band-Aid and Loratadine Tablets. Ranked by DDDc, the largest daily cost was Budesonide and Formoterol Fumarate Powder for Inhalation. As age increases, the intensity of drug use increased; The intensity of drug use in women was greater than that in men. The intensity of drug use was different for different categories personnel. Conclusion Musculoskeletal system drugs are important drugs for field training. The task personnel should formulate a list of medicines for basic diseases based on their own medication for basic diseases and the duration of the task, and submit it to the medicinal material guarantee department to ensure the carrying drugs. The factors affecting modular drug support in field training include: task type, region, solar term, duration and personnel composition, etc.

Objective To observe the fundus imaging characteristics of different stages of syphilitic posterior uveitis. Methods Retrospective cases series. Forty-six eyes of 32 patients with syphilitic posterior uveitis were included. There were 14 patients (16 eyes) and 18 patients (30 eyes) were assigned to acute stage group (with the course<2 months) and chronic stage group (with the course≥2 months) respectively. All eyes received the examination of indirect ophthalmoscopy, color fundus photography, fundus fluorescein angiography (FFA) and optical coherence tomography (OCT). All patients received regular anti-syphilitic treatment. Color fundus photography and OCT were followed after treatment. The fundus imaging characteristics of different stages of syphilitic posterior uveitis were observed. Results Indirect ophthalmoscopy and fundus color photography showed that in the acute stage group, there were 3/16 eyes with optic disc edema;4/16 eyes with a yellowish, placoid lesion involving the macular. There were only some pigment alterations on the fundus after treatment. In the chronic stage group, there were 4/30 eyes with optic disc hyperemia, 3/30 eyes with cystoid macular edema. After treatment, the optic hyperemia vanished gradually, but there were still some pigment alterations. The FFA images of two groups showed various vascular leakages. In the chronic stage group, patients also showed hyper-fluorescence with cystoid macular edema. The patients with course 2–3 years have more transmitted fluorescence on FFA. OCT showed that all eyes in the acute stage group had lost the ellipsoid zone, with irregular granular reflectivity of the retinal pigment epithelium (RPE) layer, 6 eyes with subretinal fluid in the macular. After treatment, the ellipsoid zone and RPE layer structure recovered gradually. In the chronic stage group, all eyes showed widespread loss of the ellipsoid zone, pigment migration and (or) cystoid macular edema. After treatment, the ellipsoid zone showed partial recovery. The outer ellipsoid zone was still discontinuous in patients with long duration. Conclusions Syphilitic posterior uveitis patients generally had normal fundus, but some cases had a yellowish, placoid lesion involving the macular. FFA showed various vascular leakages, and the chronic stage group showed more transmitted fluorescence. The major OCT change was loss of the ellipsoid zone or with subretinal fluid. After treatment, fundus showed no abnormal manifestations except some pigment alterations;the ellipsoid zone structure recovered gradually in acute stage eyes, partially recovered in chronic stage eyes.

RESUMEN
Uveitis is a kind of inflammatory disease affected in ocular posterior segment.Uveitis sustains a long duration and causes a significant damage of visual function.It often leads to serious complications,such as cystoid macular edema (CME),cataract,glaucoma,retinal detachment and choroidal neovascularization (CNV).In the pathological process of uveitis,inflammatory factors promote the release of vascular endothelial growth factor (VEGF) through a variety of pathways.It has been verified that VEGF level is elevated in vitreous in the patients with uveiticinduced CME.Intravitreal injection of anti-VEGF drugs,including ranibizumab and bevacizumab,can improve the visual acuity in most patients with noninfectious uveitic-induced CME and CNV.However,intravitreously repeated injections of anti-VEGF drugs may be required in some patients.Intraocular injection of anti-VEGF drugs is an optional and effective way for those with persist macular edema and not being suitable for the use of corticosteroid or immunosuppressive therapy.However,anti-VEGF drugs may affect the efficacy of corticosteroid.Therefore,more clinical and basic researches are still needed.The status and progresses in the use of anti-VEGF drugs for uveitisinduced CME and CNV were reviewed.
