Journal of Chinese Physician 2021;23(5):654-657
Objective:To compare clinical characteristics of acute and chronic central serous chorioretinopathy (CSC).Methods:41 patients with CSC in the First Affiliated Hospital of Soochow University were studied, according to the course, they were divided into acute central serous chorioretinopathy group (A group, 29 eyes of 29 cases) and chronic central serous chorioretinopathy group (B group, 12 eyes of 12 cases). All patients underwent the best corrected visual acuity (BCVA), subretinal fluid thickness (SRF) and subfoveal choroidal thickness (SFCT) examination. The imaging characteristics of fundus fluorescein angiography (FFA) and optical coherence tomography angiography (OCTA) were compared between the two groups.Results:The BCVA, SRF and SFCT in A group were higher than those in B group ( P<0.05). FFA in group A showed that the leakage of ink diffusion or smoke type fluorescein leakage. FFA in group B showed that the fluorescein leakage was single or multiple in macular area, and atrophy of retinal pigment epithelium (RPE) cells was observed. OCTA of group A showed that the choroidal capillary layer showed high blood flow signal, low blood flow signal around the outside, or coarse granular high signal, and no choroidal neovascularization (CNV) was found. OCTA in group B showed that the image of choroidal capillary layer was similar to that of group A, but in group B, 2 eyes (2/12) had CNV with obvious morphology. Conclusions:Clinical characteristics of acute and chronic central serous chorioretinopathy are different. OCTA has definite application value in follow-up and detection of CNV.

Objective To study the relationship between the serum level of cholinesterase (CHE) and patient's clinical characteristics and serum levels of lactic dehydrogenate(LDH) and β2-microglobulin (β2-MG) in non-Hodgkin lymphoma(NHL) patients. Methods The levels of CHE, LDH, β2-MG were detected with rate method and immunoassay respectively in 74 patients, and then these patients were divided into low (38 patients) and high level groups (36 patients) according to the serum CHE levels, compared with clinical characteristics and serum levels of LDH and β2-MG between the two groups. Results There were a significant difference in serum levels of CHE, LDH, β2-MG between the low and the high CHE level group [(3714.2 ±1207.1) U/L, (435.7±364.4) U/L, (4.3±2.9) mg/L; (7898.2± 1550.5) U/L, (247.4±134.8) U/L, (2.7±1.2) mg/L, respectively] (t =10.510, P =0.000; t =2.969, P =0.005; t =3.043, P =0.004, respectively). There were no statically significance in age, pathology type, leukocyte and platelet between the low and high serum CHE level groups (t =0.166, P =0.868; x2 =0.751, P=0.386; t =1.626, P=0.111; t =1.987, P=0.056, respectively). Patients with low CHE level group were mostly in Ann Arbor Ⅲ-Ⅳ period (x2 =9.394, P =0.024) and mostly male patients compared with the high CHE level group patients (x2 =5.432, P =0.020). The quantity of hemoglobin in the low CHE level group(97.6±25.8) g/L were lower than that of the high level group (113.4±15.2) g/L (t = 3.230, P =0.002). Conclusion The low CHE level was not correlated with age, pathology type, leukocyte and platelet, but was related with male, Ann Arbor Ⅲ-Ⅳ period, anemia, and higher expression of LDH, β2-MG.
