The fovea avascular area (FAZ) is an area of the retina surrounded by a continuous capillary plexus that does not have any capillary structure of its own. FAZ is an important region for the formation of fine vision function. The changes of its morphology and surrounding capillary density reflect the degree of macular ischemia, and are closely related to retinal vascular diseases such as diabetic retinopathy, retinal vein occlusion, Coats disease, idiopathic macular telangiectasia, and retinopathy of prematurity. Early observation of FAZ region changes in patients with retinal vascular disease by optical coherence tomography angiography (OCTA) can evaluate the severity and prognosis of the disease. However, the measurement error of FAZ-related data is still a problem that cannot be ignored. At present, OCTA devices of various manufacturers have different methods and algorithms for measuring and analyzing FAZ, which makes it impossible to compare the measured data between different devices. It is believed that with the continuous progress of OCTA related technology, more accurate data of FAZ regional changes can be obtained, which will bring more help to clinical work.

Electrocardiogram (ECG) was observed, superoxide dismutase(SOD) activity, and the contents of malondialdehyde(MDA) and nitric oxide (NO) in the myocardial homogenate as well as serum and glutamate oxaloacetate transaminase (GOT) were observed after ISO injection. Results XGSDP could significantly increase NO content and SOD activity, decrease contents of MDA and GOT and reduce the positive rate of ECG( P

Objective To observe the clinical efficacy of acupuncture plus rehabilitation training in treating post-stroke depression.Method Forty-one patients with post-stroke depression were randomized into a treatment group of 22 cases and a control group of 19 cases. In addition to the basic internal medicine treatment, the treatment group received acupuncture plus rehabilitation training, while the control group was intervened by rehabilitation training alone. The Hamilton Depression Scale (HAMD) and National Institutes of Health Stroke Scale (NIHSS) were observed and compared before and after treatment.Result The HAMD and NIHSS scores in the two groups were significantly changed respectively after 4-week and 8-week treatment (P<0.05,P<0.01). Respectively after 4-week and 8-week treatment, the HAMD and NIHSS scores in the treatment group were significantly different from that in the control group (P<0.05,P<0.01).Conclusion Acupuncture plus rehabilitation training is an effective approach in treating post-stroke depression.

Objective To investigate the correlation between Hcy and blood lipid level and its diagnostic value in patients with cerebral infarction.Methods 218 patients with cerebral infarction were divided into the cerebral infarction group and no cercbral infarction group,based on the diagnosis results of head CT or MRI,and 60 healthy individuals were used as the control group.The levels of serum TC,TG,HDL-c,LDL-c and serum Hcy were determined in each group.The level of serum Hcy was used as a diagnostic-test and the criterion of cerebral infarction which was diagnosed by using head CT or MRI was used as a gold standard.Meanwhile,the sensibility,specificity,predictive value and likelihood ratio of Hcy were measured in patients with and without cerebral infarction.Results Levels of TC and Hcywere significantly elevated (P ＜ 0.01),but HDL-c level was significantly decreased in patients with and without cerebral infarction compared with the healthy people (P ＜ 0.05).Hcy level was shown negatively correlated with HDL-c (r =-0.144,P ＜ 0.05).The sensibility and specificity of Hcy in both two groups of patients with and without cerebral infarction were 42.20％ and 54.13％,the positive predictive value and negative predictive value of Hcy were 47.92％ and 48.36％,the positive likelihood ratio and negative likelihood ratio of Hcy were 0.92 and 1.07,respectively.Conclusion Hcy and blood lipid have definite correlation,but Hcy has low diagnostic value for cerebral infarction and may not be used as a biological marker for the cerebral infarction diagnosis.

Objective:To analyze the radiographic parameters of shoulder balance that affect the postoperative satisfaction of Lenke type 1 adolescent idiopathic scoliosis (AIS).Methods:A total of 98 patients with AIS who underwent posterior pedicle screw fusion in Xijing Hospital of Air Force Medical University from August 2017 to July 2020 were retrospectively analyzed. There were 26 males and 72 females, aged 15.2±5.3 years (range, 10-24 years). Distribution of upper instrumented vertebrae: T 2 58 cases (59%), T 3 25 cases (26%), T 4 15 cases (15%); Distribution of lower instrumented vertebrae: T 12 63 cases (64%), L 1 28 cases (29%), L 2 4 cases (4%), L 3 3 cases (3%). Clavicle angle (CA), radiographic shoulder height (RSH), and coracoid height difference (CHD), clavicle-rib cage intersection difference (CRID), T 1 tilt angle, first rib tilt angle, clavicle chest angle difference(CCAD) and Scoliosis Research Society-22 (SRS-22) scale were compared before and after operation. Binary logistic regression was used to analyze the radiographic indicators of shoulder balance that affected the postoperative satisfaction of Lenke type 1 AIS. The receiver operating characteristic (ROC) curve was drawn to determine the threshold value of the imaging index. Results:All operations were successfully completed. The operation time was 260±80 min (range, 220-320 min), and the intraoperative blood loss was 360±110 ml (range, 300-700 ml). There was no nerve, dural or vascular injury during operation. RSH, CHD, CRID, T 1 tilt angle, first rib tilt angle, and CCAD at the final follow-up were 4.0 (0, 13.9) mm, 7.0 (0, 12.9) mm, 4.0 (0, 10.0) mm, 4.8° (3.3°, 8.2°), 5.3°±3.9°, and 5.5° (3.0°, 8.9°), respectively, which were less than the preoperative 10.6 (2.0, 20.3) mm, 10.3 (2.5, 15.9) mm, 8.0 (1.0, 15.2) mm, 7.6° (3.5°, 12.2°), 7.5°±6.9°, 8.5° (3.6°, 18.3°), and the difference was statistically significant ( P<0.05). The SRS-22 function, pain, appearance, and psychological scores at the final follow-up were 4.6 (4.0, 4.9), 4.1±0.5, 4.1±0.7, and 4.2 (3.9, 4.8) points, respectively, which were greater than the preoperative scores of 4.2 (3.8, 4.6), 4.0±0.7, 3.5±0.7, and 4.0 (3.5, 4.4) points, the difference was statistically significant ( P<0.05). Binary logistic regression showed that CCAD was an independent radiographic indicator of shoulder balance that affected the satisfaction of AIS patients after orthopaedic surgery ( OR=0.826, P=0.040). ROC curve showed that the area under the curve and 95% CI was 0.726 (0.572, 0.865), and the threshold was 6.6°. Conclusion:CCAD is an independent radiographic parameter of shoulder balance that affects the postoperative satisfaction of AIS. Patients are more likely to achieve a satisfactory outcome when their postoperative CCAD is ≤6.6°, which can be used clinically as a radiographic parameter to assess the efficacy of orthopaedic spine surgery.

Objective To evaluate the diagnostic value of ultrasound-guided fine needle aspiration cytology(US-FNAC)in the assessment of radiologically detected ovarian neoplasms and retroperitoneal metastatic lymph nodes. Methods FNAC was performed under ultrasound guidance on 126 patients suspected of ovarian neoplasms and retroperitoneal metastatic lymph nodes. Cytologic examination was performed after staining smears with the haematoxylin and eosin method. Clinical data were retrieved from the medical records and all cytological specimens were reviewed. In these cases, the cytologic findings were correlated with histology of the primary tumor and were compared with surgical pathology. Results Satisfactory sampling was obtained in 86.2% of punctures, and cytological diagnosis was made in 85.7% cases. The size of the lymph nodes punctured was less than 20 mm in 93.5% cases, with the sensitivity of 81.6%、86.2%, specificity of 95.8%、100.0%, positive predictive value of 98.3%、100.0%, negative predictive value of 63.9%、33.3%, and accuracy of 85.3%、87.1%. Seven patients presented slight abdominal discomfort, and relieved without clinical treatment. Conclusions The fine needle aspiration technique has excellent positive predictive value and low morbidity. US-FNAC, as the valuable investigation, is not only useful in the diagnosis of ovarian masses and lymph nodes but can also help in choosing appropriate management. From our experience, US-FNAC can be added in follow-up of selected patients in whom the cytological identification of such masses and nodes is significant for the patient′s treatment.

Objective To observe the therapeutic effect of extracorporeal shock wave therapy combined withsurface electromyography biofeedback training(ESW-sEMGBF)on post-traumatic elbow joint stiffness.Methods A total of 80 patients with post-traumatic elbow stiffness admitted to the Rehabilitation Department of Hangzhou Fuyang Hospital of Orthopedics of Traditional Chinese Medicine from January 2021 to December 2021 were randomly assigned into control group(n = 40)and treatment group(n = 40)using a lottery method.The control group received conventional rehabilitation treatment(including soft tissue release,joint mobilization,continuous passive motion and cold therapy),and the treatment group received conventional treatment combined with ESW-sEMGBF.Both groups underwent training once daily for five days a week over eight weeks.The visual analogue scale(VAS),active range of motion(AROM)of the elbow joint,and Mayo Elbow Performance Score(MEPS)were evaluated before and after treatment.Results After 8 weeks of treatment,significant improvements were observed in all outcomes for both groups.The treatment group showed better improvements in VAS scores,AROM,and MEPS after treatment compared with the control group(P<0.05,P<0.001,P<0.001).No side effects or adverse reactions were observed in either group after treatment.Conclusion Extracorporeal shock wave therapy combined with surface electromyography biofeedback training effectively alleviated pain in patients with post-traumatic elbow joint stiffness,improved elbow joint function,and increased active range of motion of the elbow joint.
