Anxiety-depressive disorders are closely associated and frequently comorbid with headache （especially primary headache）， which significantly increases the disease burden of patients and the difficulties of treatment. Anxiety-depressive disorders can not only increase the risk of primary headache but also directly cause headache attributed to anxiety-depressive disorders. There are complex mechanisms underlying the comorbidity of anxiety-depressive disorders and headache， and currently， there is still a lack of diagnostic criteria for "headaches attributed to anxiety-depressive disorders"， which requires future research to delve deeper into the comorbidity mechanisms and optimize diagnostic criteria. This article reviews the interrelationship between anxiety-depressive disorders and headache， as well as related advances in diagnosis， underlying mechanisms， and treatment， so as to provide help for clinical diagnosis and management.

Objective:To summarize the characteristics of color doppler flow imaging (CDFI) of ocular toxocariasis (OT) in children.Methods:A retrospective clinical study. From July 2014 to June 2020, 61 OT patients with 61 eyes diagnosed through clinical and laboratory testing in the Department of Ophthalmology of Beijing Tongren Hospital of Capital Medical University were included in the study. There were 45 males with 45 eyes and 16 females with 16 eye (male: female=2.81:1). Age were (6.93±2.50) years. The right eye and left eye were 29 and 32 eyes, respectively. Both eyes of the patient underwent two-dimensional ultrasound and CDFI examination. Two dimensional ultrasound was used to estimate the axial length (AL) of the affected eyes and healthy eyes on the opposite side. Among them, 52 cases were measured for AL using optical biometry and/or A-mode ultrasound. Vitreoretinal surgery was performed within one week after ultrasound examination. Two-dimensional ultrasound was used to observe the morphology of vitreous opacity, its connection to the eyeball wall, and whether posterior vitreous detachment and retinal detachment have occurred. CDFI examination was used to observe the presence of blood flow signals on the pathological membrane. The detection rates of different forms of vitreous opacity and traction retinal detachment were calculated. The location of proliferative lesions in the eye was analyzed. Paired t-test was performed to compare the AL of the affected eye and the healthy eye on the opposite side. Perform Kappa consistency test on the location of proliferative lesions was used during CDFI examination and vitreoretinal surgery. Results:All affected eyes have varying degrees of vitreous opacity. Among them, 23 eyes (37.7%, 23/61) showed typical "Christmas tree" like turbidity; 27 eyes (44.3%, 27/61) had clustered and striped echoes; 9 eyes (14.8%, 9/61) had weak punctate and strip echoes. Two eyes (3.3%, 2/61) showed a large amount of dense punctate and strip-shaped echoes. There were 50 eyes (82.0%, 50/61) with traction retinal detachment, of which 46 eyes (92.0%, 46/50) had visible blood flow signals on the detached retina, and the remaining 4 eyes (8.0%, 4/50) had no blood flow signals. During CDFI and surgery, there were 5 (8.2%, 5/61) and 4 (6.6%, 4/61) eyes with visible proliferative lesions in the periphery, respectively; 18 (29.5%, 18/61) and 14 (23.0%, 14/61) eyes were distributed in the posterior pole, respectively; there were 38 (62.3%, 38/61) and 43 (70.5%, 43/61) eyes with both peripheral and posterior polar regions, respectively. The consistency between CDFI and surgery in detecting the location of proliferative lesions was good ( κ=0.832, 95% confidence interval 0.691-0.973, P<0.001). The two-dimensional ultrasound measurement results showed that the AL of the affected eye was shorter than that of the contralateral healthy eye in 46 cases (75.4%, 46/61). Among the 52 patients who underwent AL biometry, the AL of the affected eye was shorter than that of the contralateral healthy eye by (0.63±0.68) mm, and the difference was statistically significant ( t=-6.738, P<0.05). Conclusions:CDFI can clearly display various intraocular lesions (vitreous opacity and traction retinal detachment) and eyeball sizes in children with OT. Vitreous opacity is often manifested as "Christmas tree" like, clustered, strip-shaped.

Objective:To evaluate the feasibility of measurement and characteristics of intraocular lens (IOL) tilt using the swept-source optical coherence tomography (SS-OCT) biometer (IOLMaster 700) and to explore its potentially relevant parameters.Methods:A cross-sectional study was conducted.Two hundred and forty-two eyes (119 right eyes, 123 left eyes) of 185 patients after phacoemulsification and IOL implantation were included in Beijing Tongren Hospital from July to September 2018.The IOL position, angle κ, angle α, corneal curvature, anterior chamber depth (ACD), pupil diameter (PD), and axial length (AL) were obtained by IOLMaster 700, and the IOL tilt direction and magnitude were calculated.The within-subject standard deviation and intraclass correlation coefficient were used to evaluate the repeatability of three IOL tilt measurements.Binocular symmetry of IOL tilt and the correlation between IOL tilt and different influencing factors were evaluated by Pearson linear correlation analysis or Spearman rank correlation analysis.Influencing factors for IOL tilt were assessed by multiple linear regression analysis.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Beijing Tongren Hospital, Capital Medical University (No.TRECKY2018-049). Patients were informed of the purpose and methods of this study and signed the written informed consent.Results:The repeatability of IOL tilt measurements was excellent with a within-subject standard deviation of 5.16° for IOL tilt direction and 0.13° for IOL tilt magnitude.IOL tilt was mirror symmetric in both eyes.The IOL tilt direction in right eyes ranged from -89.60° to 87.53° with a mean of (18.85±29.65)°, and the tilt magnitude ranged from 1.32° to 7.05° with a mean of (4.16±1.26)°.The IOL tilt direction in left eyes ranged from -84.30° to 89.44° with a mean of (21.17±32.38)°, and the tilt magnitude ranged from 0.58° to 7.40° with a mean of (3.80±1.31)°.There were moderate and weak positive correlations of IOL tilt direction and tilt magnitude between both eyes ( r=0.473, P<0.001; r=0.335, P=0.011). IOL tilt magnitude was weakly positively correlated with angle α and IOL diopter ( rs=0.272, P=0.003; r=0.285, P=0.002), and was weakly negatively correlated with ACD, PD and AL ( r=-0.303, P=0.001; r=-0.233, P=0.011; rs=-0.331, P<0.001). In backward stepwise regression analysis, the regression equation of IOL tilt magnitude, angle α, ACD, PD, AL and IOL diopter in multiple linear regression analysis was as follows: IOL tilt magnitude=10.503+ 1.456×angle α-0.532×ACD-0.196×AL ( R2=0.400; F=8.588, P<0.001). Conclusions:The SS-OCT biometer can be an effective method to assess IOL tilt.IOL tilt is mirror symmetric between the right eyes and left eyes.

Objective:To evaluate the efficacy and safety of oral anisodine hydrobromide tablets in the treatment of nonarteritic anterior ischemic optic neuropathy (NAION).Methods:A multicenter nonrandomized controlled trial was conducted.A total of 282 acute NAION patients (282 eyes) were recruited from 16 hospitals in China from July 2020 to May 2021.Patients were divided into two groups according to treatment methods, which were control group (124 cases, 124 eyes) receiving regular treatment including citicoline sodium plus Ginkgo biloba leaf liquid extract or Ginkgo biloba leaf extract tablets plus mecobalamin, and experimental group (158 cases, 158 eyes) receiving treatment in control group plus oral anisodine hydrobromide tablets 1 mg, twice daily for 2 to 3 months.Best corrected visual acuity (BCVA), visual field index (VFI), peripapillary retinal nerve fiber layer (pRNFL) and radial peripapillary capillary vessel density (RPC) were assessed at 1, 2, 3, and 6 months after enrollment using the standard decimal visual acuity chart, 750i Humphery visual field analyzer, Cirrus HD-OCT 4000/Cirrus HD-OCT 5000, RTVue-XR optical coherence tomography respectively.The primary outcomes were BCVA and VFI, and the secondary outcomes were pRNFL, RPC, and the side effects during the follow-up.The study adhered to the Declaration of Helsinki.All patients were fully informed about the treatment and purpose of this study and voluntarily signed the informed consent form.The study protocol was approved by Chinese PLA General Hospital (No.S2020-021-01). Results:In all, 242 patients (242 eyes) completed the follow-up of BCVA, and 98 patients (98 eyes) completed the VFI follow-up.In terms of visual function, BCVA and VFI improved significantly over time in the two groups, and BCVA and VFI were better in experimental group than in control group at various follow-up time points (all at P<0.05). In terms of structure, pRNFL gradually decreased in both groups with the extension of treatment, and pRNFL was significanthy thinner in experimental group than in control group at various follow-up time points (all at P<0.05). There was no significant difference in RPC between the two groups at the last follow-up ( P>0.05). There were two cases with side effects and one case was discontinued due to side effects 25 days after enrollment. Conclusions:Oral anisodine hydrobromide can improve visual acuity and visual field in NAION and accelerate the regression of optic disc edema, with good safety.

Objective To evaluate the effect of esketamine for cesarean section under epidural an-esthesia and maternal and fetal outcome.Methods The parturients all were singleton pregnancies at term and scheduled for elective cesarean delivery.Ninety parturients undergoing elective cesarean delivery under epidural anesthesia,aged 20-40 years,BMI 18-35 kg/m2,ASA physical status Ⅱ,were randomly alloca-ted into two groups:esketamine group(group K)and control group(group C),45 cases in each group.When the targeted upper sensory block level was achieved,esketamine 0.15 mg/kg was administered intra-venously for 1 minute before skin incision in group K,the same volume of normal saline was intravenously injected in group C.Visceral traction reaction during the operation was recorded.Apgar score was assessed 1 minute and 5 minutes after birth.The pH value,partial pressure of carbon dioxide,oxygen partial pressure,and lactic acid value of the neonatal umbilical vein blood were recorded.Adverse events such as nausea,vomiting,hallucination,dizziness and nightmare were monitored in the two groups.Results Compared with group C,visceral traction reaction was significantly lower in group K(P＜0.05).The neonatal Apgar score,pH value,carbon dioxide partial pressure,oxygen partial pressure,and lactic acid value of the neo-natal umbilical vein blood did not differ between the two groups.There were no differences in the incidence of nausea,vomiting and dizziness between the two groups.Hallucinations and nightmares were not encoun-tered in either group.Conclusion Esketamine 0.15 mg/kg can effectively reduce visceral traction reaction during cesarean delivery under epidural anesthesia.There was no significant effect on neonatal Apgar score and blood gas analysis,with no noticeable maternal and neonatal adverse effect.

Objective:To analyze the ultrasonographic features of adenoma of the nonpigmented ciliary epithelium (ANPCE).Methods:A retrospective series of case studies. From January 2014 to October 2021, 31 patients (31 eyes) with ANPCE (ANPCE group) were diagnosed in the eye center of Beijing Tongren Eye Center of Beijing Tongren Hospital, Capital Medical University, and 17 patients (17 eyes) with ciliary body melanoma (control group) diagnosed at the same time were selected as the control group. There was no significant difference in age ( t=-0.564) and sex composition ratio ( χ 2=0.182) between the two groups ( P=0.576, 0.670). All patients underwent ultrasound biomicroscopy to obtain the measurement parameters: tumor height, maximum basal diameter, maximum diameter, ratio of maximum diameter to basal diameter and ratio of maximum diameter to height; tumor location, shape, internal echogenicity intensity, echogenicity uniformity, degree of sound attenuation, invasion of iris, anterior displacement of the iris, lens subluxation were observed. The measurement parameters and observation indexes of the two groups were compared by independent sample t-test and χ 2 test. Receiver operating characteristic (ROC) curve was drawn, area under the ROC curve (AUC) was determined, and parameter indicators with differential diagnosis value were screened. Results:The maximum diameter, height, maximum basal diameter, ratio of the maximum diameter to the maximum basal diameter, and the ratio of the maximum diameter to the height of the tumors in the ANPCE group and the control group were 5.64±0.98 mm, 4.24±0.59 mm, 3.66±0.71 mm, 1.58±0.34, 1.34±0.19 and 7.82±2.03 mm, 4.47±2.44 mm, 7.02±1.96 mm, 1.13±0.16, 2.09±1.06. The maximum diameter, the maximum basal diameter, and the ratio of the maximum diameter to the height of the tumor in the ANPCE group were all smaller than those of the control group, and the ratio of the maximum diameter to the maximum basal diameter was greater than that of the control group, and the differences were statistically significant ( t=-4.159,-6.808, -2.924, 6.257; P<0.05). The tumors in the ANPCE group were mainly spherical (87.1%, 27/31), with no significant acoustic attenuation (77.4%, 24/31), less invading the root iris (77.4%, 24/31), and the tumors were mostly located in the ciliary body coronal (74.2%, 23/31); tumors in the control group were mainly hemispherical (47.1%, 8/17) or spherical (47.1%, 8/17), with significant sound attenuation (76.5%, 13/17), most of the tumors invaded the iris (70.6%, 12/17), and the tumors were mostly located from the pars plana to the coronal (76.5%, 13/17). There were statistically significant differences in the position, shape, sound attenuation degree, and whether it invaded the iris between the two groups of eyes ( χ 2=15.132, 19.767, 13.118, 10.581; P<0.05). The results of ROC curve analysis showed that the ratio of the largest diameter to the largest base diameter, the degree of sound attenuation and the AUC of whether the iris was violated were higher, which were 0.881, 0.769, and 0.740, respectively. Conclusions:Ultrasound biomicroscopy is helpful in the diagnosis and differential diagnosis of ANPCE and ciliary body melanoma. The ratio of maximum diameter to maximum basal diameter, the degree of sound attenuation and whether it invades the root iris are important parameters to distinguish the two tumors.

Objective:To summarize and discuss the surgical effect in otoplasty of prominent ear using cartilage folding with unilateral cartilage incision.Methods:Data of patients with prominent ear who were treated in the Department of Vascular and Plastic Surgery of Guangdong Provincial People’s Hospital and the Department of Plastic Surgery of Sun Yat-sen Memorial Hospital from May 2018 to April 2022 were retrospectively analyzed. All patients underwent otoplasty using cartilage folding with unilateral cartilage incision. During the operation, a unilateral cartilage incision was made along the lateral bottom of intended antihelix, cartilage dissection and scoring were made, and the cartilage was folded and sutured to form the antihelix. The patients were followed up postoperatively for auricular shape, wound healing and other complications.Results:A total of 18 patients with prominent ear (22 ears) were included, consisting of 12 males (15 ears) and 6 females (7 ears), aged from 18 to 51 years(average of 25.8 years). There were 9 cases on the left, 5 cases on the right and 4 cases on both sides. Four patients had pain in the operation area within 2 days postoperatively which could be relieved by analgesics. The patients were followed up for 1-24 months, with an average follow-up of 13.6 months. Twenty-two prominent ears were corrected. Scaphoconchal angle and cranioauricular angle of the prominent ears were significantly reduced, and the shape of the antihelix was smooth after the operation. All patients were satisfied with the results. There were no other complications after the operation, such as deformity relapse, infection, unhealing, auricular cartilage deformation and hypertrophic scar.Conclusions:Otoplasty of prominent ear using cartilage folding with unilateral cartilage incision is a simple, stable and satisfactory surgical method for the treatment of prominent ear.

Objective:To discuss the characteristics of ultrasound diagnosis of optic disc capillary hemangioma.Methods:The study analyzed retrospectively 7 cases of optic disc capillary hemangioma diagnosed in the Beijing Tongren Hospital from 2015 to 2018. The size, morphology, internal echo, and secondary changes of the lesion were analyzed during ultrasound examination.Color Doppler flow imaging was used to check the blood flow in the lesion.Results:Pre-optic disc occupying lesions could be detected in the ultrasound images of the 7 cases. Lesion size: average base diameters (5.39±1.90)mm×(4.79±1.28)mm, average height (3.61±1.37)mm. Lesion morphology: 5 cases were round, and 2 cases were irregular. Echo within the lesion: 3 cases had medium echo inside the lesion, and 4 cases had high echo inside the lesion. Internal echo characteristics: 5 cases had uniform echo, and 2 cases had uneven echo. Secondary changes: 6 cases had secondary retinal detachment and vitreous opacity, and 1 cases was accompanied by retinal hemangioma in other parts. In all cases, blood flow signals could be detected inside the space-occupying lesions, which were in the form of branches, stripes or spots, and the blood flow spectrum showed a parallel spectrum of arteries and veins.Conclusions:Ultrasound examination of optic disc capillary hemangioma has certain characteristics, which can provide a valuable follow-up basis for clinical diagnosis.

Objective:To analyze the perfusion characteristics of choroidal metastasis using contrast-enhanced ultrasound, and compare with choroidal hemangioma.Methods:This was a retrospective study.From January 2016 to February 2018 in Beijing Tongren Hospital, a total of 21 eyes from 21 patients who were clinically diagnosed as choroidal metastasis were included as the choroidal metastasis group and 46 eyes from 46 patients who were diagnosed as choroidal hemangioma during the same period were included as the choroidal hemangioma group. All patients underwent contrast-enhanced ultrasound examination, and Sonoliver was used to obtain the data on quantitative parameters of the tumor and the adjacent normal orbital tissues, including maximum of intensity (IMAX), rise time (RT), time to peak (TTP), and mean transit time (mTT). The quantitative parameters between choroidal metastasis and normal orbital tissues were compared. And the quantitative parameters between choroidal metastasis and choroidal hemangioma were compared. The receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic performance.Results:The IMAX of choroidal metastasis was significantly higher than that of normal orbital tissues, while RT, TTP and mTT were significantly shorter than these of normal orbital tissues (all P<0.01). The IMAX of choroidal metastasis was lower than that of choroidal hemangioma, and RT, TTP and mTT were shorter than choroidal hemangioma (all P<0.01). The ROC curve analysis showed that area under curves of the IMAX, RT, TTP and mTT were 0.775 (95% CI=0.666-0.884), 0.970 (95% CI=0.896-0.996), 0.729 (95% CI=0.607-0.831) and 0.992 (95% CI=0.931-1.000) respectively. The sensitivities were 71.7%, 95.7%, 76.1% and 95.7%, and the specificities were 85.7%, 90.5%, 66.7% and 95.2%, respectively. Conclusions:Contrast-enhanced ultrasound can reflect the differences in perfusion characteristics between choroidal metastasis and choroidal hemangioma. RT and mTT are useful parameters in differential diagnosis between the two types of tumors.
