ABSTRACT
Background@#in vitro culture of preantral follicles is a promising technology for fertility preservation. @*Objectives@#This study aims to investigate an optimized three-dimensional (3D) fetal bovine serum (FBS)-free preantral follicle culture system having a simple and easy operation. @*Methods@#The isolated follicles from mouse ovaries were randomly divided in an ultra-low attachment 96-well plates supplement with FBS or bovine serum albumin (BSA) culture or encapsulated with an alginate supplement with FBS or BSA culture. Meanwhile, estradiol (E 2 ) concentration was assessed through enzyme-linked immunosorbent assay of culture supernatants. The diameter of follicular growth was measured, and the lumen of the follicle was photographed. Spindle microtubules of oocytes were detected via immunofluorescence.The ability of oocytes to fertilize was assessed using in vitro fertilization. @*Results@#The diameters were larger for the growing secondary follicles cultured in ultra-low attachment 96-well plates than in the alginate gel on days 6, 8, and 10 (p < 0.05). Meanwhile, the E 2 concentration in the BSA-supplemented medium was significantly higher in the alginate gel than in the other three groups on days 6 and 8 (p < 0.05), and the oocytes in the FBS-free system could complete meiosis and fertilization in vitro. @*Conclusions@#The present study furnishes insights into the mature oocytes obtained from the 3D culture of the preantral follicle by using ultra-low attachment 96-well plate with an FBSfree system in vitro and supports the clinical practices to achieve competent, mature oocytes for in vitro fertilization.
ABSTRACT
Objective:To investigate the prevalence of depression symptoms in residents, and to analyze the demographic characteristics, training status and psychological influencing factors in order to provide the evidence for the mental health management and intervention of residents in China at current stage.Methods:A total of 1 050 participants from eight different training centers in Shenyang, Dalian, Jinzhou and Fushun of Liaoning Province were investigated by Pittsburgh sleep quality index, International physical activity questionnaire, Survey of perceived organizational support, Psychological capital questionnaire and Minnesota satisfaction questionnaire, which covered questions including social demographic information, training information, sleep status, physical activity, organization support, psychological capital, job satisfaction and depressive symptoms of residents. SPSS 22.0 were used to carry out statistical analysis such as logistic regression.Results:A total of 962 valid questionnaires were collected and the results showed that 44.59% (429/962) of residents had depressive symptoms. High training grade ( ORPGY-3=1.775, P=0.006) and poor quality of sleep ( OR=1.662, P<0.001) were risk factors of depressive symptoms, whereas psychological capital ( OR=0.962, P<0.001) and job satisfaction ( OR=0.972, P=0.001) were protective factors of depressive symptoms. Conclusion:The prevalence of depressive symptoms is high in residents. Training grade, sleep quality, psychological capital and job satisfaction are closely associated with the high prevalence of depressive symptoms, which should be paid more attention to.

ABSTRACT
Forsythiae Fructus is the dried fruit of Forsythia suspensa and the volatile compounds are its main bioactive components. According to the different harvest periods, F. suspensa can be divided into Qingqiao(mature F. suspensa) and Laoqiao(ripe F. suspensa). To investigate dynamic changes of volatile components in Qingqiao and Laoqiao samples collected at different periods, the present study extracted and analyzed the total volatile oils in Qingqiao and Laoqiao samples(four harvest periods for Qingqiao and two for Laoqiao) by steam distillation method. The results indicated that the content of volatile oils in F. suspensa samples at different harvest periods was significantly different. The content of volatile oils in Qingqiao samples(except those harvested in the first period) was higher than that of Laoqiao, and the content of volatile oils in both Qingqiao and Laoqiao increased with the harvest period. Furthermore, volatile compounds in F. suspensa were qualitatively analyzed by the gas chromatography-mass spectrometry(GC-MS), and 28 volatile compounds were identified. Chemometrics analyses including principal component analysis(PCA) and partial least squares discriminant analysis(PLS-DA) were further applied to explore differential markers and dynamic changes of volatile components in Qingqiao and Laoqiao samples at different harvest periods. Finally, four volatile compounds, including α-pinene, sabinene, β-pinene, and 4-terpenol were selected as potential differential markers. The relative content of α-pinene and 4-terpenol was consistent with that of total volatile oils in the changing trend.

Objective:To investigate the role of methylation status of glutathione transferase mu5 (GSTM5) promoter region in the occurrence and development of myelodysplastic syndrome (MDS) and provide a new potential molecular marker for the early diagnosis of MDS.Method:Bone marrow blood samples were collected from 40 patients with initial diagnosis of MDS [5 cases of MDS with single dysplasia (MDS-SLD), 7 cases of MDS with multilineage dysplasia (MDS-MLD), 6 cases of MDS with ringed sideroblasts (MDS-RS), 13 patients with refractory with excess blast-1 (RAEB1), 9 patients with refractory with excess blast-2 (RAEB2)], 8 patients with AML secondary to MDS and 6 patients with non-malignant blood diseases(4 patients with iron deficiency anemia and 2 patients with nutritional megaloblastic anemia) in PLA General Hospital from October 2018 to June 2021. Methylation status of the promoter region of GSTM5 gene in three groups were detected by the Agena MassArray nucleic acid mass spectrometry. The Wilcoxon nonparametric test (non-normally distributed data, median (IQR)] was used to compare the methylation levels of GSTM5 gene in different groups. Receiver operating characteristic (ROC) curve was used to evaluate the specificity, sensitivity and accuracy of the test.Results:Cluster analysis showed that the methylation status of GSTM5 in MDS group was higher than that in control group [0.50 (0.27, 0.79) vs.0.29(0.10, 0.45), P<0.05]; The methylation status of GSTM5 in sAML group was significantly higher than that in MDS group [0.67 (0.36, 0.86) vs. 0.50 (0.27, 0.79), P<0.05].The differences in the methylation status of each CpG site were analyzed, and there were statistically significant differences between the MDS group and the control group at CpG_1, CpG_4, 5, CpG_6, 7, 8, CpG_11, CpG_13, 14, CpG_15, CpG_16, CpG_22 and CpG_24 sites ( P<0.05). The results of ROC curve analysis showed that the area under the CpG_6, 7, 8 site curves was the largest, with AUC=0.861(95% CI 0.717-1.000; P<0.05), and the sensitivity and specificity were 85% and 83%, respectively. By analyzing the relationship between GSTM5 methylation and MDS disease development, GSTM5 methylation levels were significantly increased in the higher bone marrow blast group and the high-risk subgroup (RAEB). Conclusion:Aberrant DNA promoter methylation of GSTM5 was a frequent event in MDS and may play an important role in the occurrence and development of MDS. It might be served as a promising biomarker in the diagnosis of MDS.
ABSTRACT
Objective:To investigate the clinical characteristics, treatment and prognosis of primary vitreoretinal lymphoma (PVRL) diagnosed and treated in our hospital during the past 10 years.Methods:A retrospective clinical study. From 2011 to 2021, 126 eyes of 67 patients with PVRL who were diagnosed and treated in Department of Ophthalmology, Eye-ENT Hospital, Fudan University were included in the study. Among them, there were 23 males (34.3%, 23/67) and 44 females (65.7%, 44/67); the average age was 57.1 years. There were 59 cases with both eyes (88.1%, 59/67) and 8 cases with one eye (11.9%, 8/67). At the initial eye diagnosis, 22 cases had a clear history of primary central nervous system lymphoma (PCNSL); 5 cases were found to have intracranial lesions by head imaging examination; 40 cases had no central nervous system involvement. Twenty cases were treated with glucocorticoids due to misdiagnosed uveitis. All patients received intravitreal injection of methotrexate (IVM) treatment. The treatment regimen was twice a week in the induction period for 2 weeks, once a week in the consolidation period for 1 month, and once a month in the maintenance period. Patients with PCNSL or both eyes received concurrent systemic chemotherapy (chemotherapy), and some in combination with radiation therapy to the brain (radiotherapy). The mean follow-up time was 39.3 months. The clinical manifestations, treatment and prognosis of the patients were retrospectively analyzed. The visual acuity before and after treatment was compared by t test. Results:Among the 22 cases with a clear history of PCNSL at the initial eye diagnosis, the average time from intracranial diagnosis to eye diagnosis was 22.9 months. Among the 40 cases without central nervous system involvement at first, 14 cases (20.9%, 14/67) developed central nervous system lesions during follow-up period. The mean time from ocular diagnosis to intracranial diagnosis was 9.9 months. Among the 126 eyes, 42 eyes (33.3%, 42/126) had anterior segment inflammation. vitreous inflammation type, retinal type, and vitreous retinal type were 58 (46.0%, 58/126), 7 (5.6%, 7/126), and 61 (48.4%, 61/126) eyes, and 9 of them (7.1%, 9/126) had optic nerve involvement at the same time. Patients received an average of 12 IVM treatments. IVM combined with systemic chemotherapy in 59 cases (88.1%, 59/67), of which 16 cases were combined with brain radiotherapy. All patients achieved complete remission after completing the treatment cycle (100.0%, 67/67). After treatment, 21 eyes (16.7%, 21/126) had ocular recurrence; 22 (32.8%, 22/67) had intracranial recurrence; 8 cases (11.9%, 8/67) died. The mean progression-free survival of patients was 23.7 months; the mean survival time was 43.6 months; the 5-year overall survival rate was 72.5%.Conclusions:The manifestations of PVRL are complex and diverse, and most of them are accompanied by involvement of the central nervous system. It can be divided into vitreitis type, retinal type and vitreoretinal type, and the optic nerve can be involved at the same time; IVM combined with systemic treatment can completely relieve the disease.
ABSTRACT
Objective:To observe the changes of varicella zoster virus (VZV)-DNA load in aqueous humour samples in VZV-induced acute retinal necrosis (ARN) in the early stages of antiviral treatment.Methods:A retrospective observational clinical study. From April 2016 to April 2018, 24 patients with 24 eyes of VZV-induced ARN who were diagnosed by Department of Ophthalmology, Eye and ENT Hospital of Fudan University and received complete aqueous humor sampling were included in the study. Among them, there were 13 males with 13 eyes, 11 females with 11 eyes; 12 left eyes and 12 right eyes; the age was 52.0±9.5 years old (39-71 years old). The time from the onset of ocular symptoms to the diagnosis of ARN was 16.6±6.1 days (7-30 days). Best-corrected visual acuity (BCVA) and ultra-wide-field fundus imaging were performed in all affected eyes. The BCVA examination was carried out using the Snellen visual acuity chart, which was converted into the logarithm of the minimum angle of resolution (logMAR) visual acuity. All patients were given intravitreal injection of 40 mg/ml ganciclovir 0.1 ml (including 4 mg of ganciclovir), 2 times a week, until the active necrotizing retinal lesions subsided, at most after the diagnosis 4 weeks, with a maximum of 9 injections. The follow-up period was 12.8±5.6 months. The aqueous humor samples were collected at presentation and 4, 7, 14, 21, 28 days after the initiation of antiviral therapy, and the VZV-DNA load was detected by real-time quantitative polymerase chain reaction. A plateau phase and a logarithmic reduction phase of the DNA load changes were observed after antiviral treatment began. Wilcoxon rank sum test was used to compare and analyze the differences in BCVA between the eyes at baseline and last follow-up.Results:The mean viral load at presentation was 8.6×10 7±1.3×10 8 copies/ml. The initial plateau phase last for an average of 7.4±2.4 days. In the following logarithmic reduction phase, the mean slope of the decline in viral load was -0.13±0.04 log/day, and the expected time for half reduction of the initial viral load was 2.5±0.7 days. After 28 days antiviral treatment, the viral load decreased to 1.7×10 5±1.8×10 5 copies/ml. In the course of the disease, rhegmatogenous retinal detachment occurred in 16 eyes. Before treatment and at the last follow-up, the logMAR BCVA of the affected eye was 1.1±0.6 and 0.8±0.7, respectively. The results of correlation analysis showed that the logMAR BCVA at the last follow-up was correlated with the initial VZV-DNA load ( r=0.467, P=0.033). Conclusion:The VZV-DNA load in the aqueous humor of eyes with VZV-induced ARN is significantly decreased after antiviral treatment, which is closely related to the clinical process of ARN.
ABSTRACT
Objective:To evaluate the standardized residency training of obstetrics and gynaecology in Shengjing Hospital of China Medical University with Milestones evaluation system of obstetrics and gynecology, and to evaluate the feedback effect of the system.Methods:An improved Milestones evaluation form was developed to evaluate the self-evaluation and clinical tutor's scores, collect the results and make a statistical analysis of the 1-3 years standardized training residents of the Shengjing Hospital of China Medical University in September 2019. GraphPad Prism 8 software was used for data collection and statistical analysis, and Box-Plots software was used for drawing analysist. Descriptive statistics method was used for the general situation of the research objects. After the students' self-evaluation and tutor's scores passed the normal distribution and variance homogeneity test, paired t test was performed, and the scores of residents from different sources were analyzed by variance analysis. Results:A total of 164 residents of obstetrics and gynaecology were evaluated, and there were significant differences between self-evaluation and teacher's evaluation in medical knowledge, learning ability and system work ( P<0.05). The competency scores of the first year residents ranged from 3.003 to 4.556, and at the end of the course they increased to 4.921 to 5.974, showing statistically significant differences in each item compared with the first year ( P<0.001). After three years of training, residents from different sources showed significant improvement ( P<0.001). Conclusion:The Milestones evaluation system of the obstetrics and gynecology can be used for the training assessment and feedback of the residents in obstetrics and gynecology specialty. The self-assessment of residents helps to understand the level of self-assessment, and the teacher's evaluation helps to correct the bias generated by self-assessment. The systematic and staged Milestones evaluation system can instruct the clinical tutors to instruct the residents in accordance with their aptitude, and give feedback on the training effect of the residency training base.
ABSTRACT
Objective:To investigate macular microvascular abnormalities in eyes with subfoveal fibrotic nodules secondary to Coats' disease.Methods:A cross-sectional study. From January 1, 2018 to July 30, 2021, 45 eyes of 45 patients diagnosed with Coats' disease with or without subfoveal fibrotic nodules in Eye and ENT Hospital, Shanghai Medical College of Fudan University were included in this study. There were 40 eyes in 40 males and 5 eyes in 5 females. All were under 21 years old. According to the presence or absence of subfoveal fiber nodules, the patients were divided into fibrotic group (26 cases, 26 eyes) and non-fibrotic group (19 cases, 19 eyes). Optical coherence tomography angiography was used to scan 3 mm×3 mm or 6 mm×6 mm macular area of both eyes. The software of the device automatically processed the images. The presence of FAZ edge anastomotic vascular arch ring breakage and abnormal microvascular branch (AMB) in the foveal avascular zone (FAZ) were observed.Results:In 26 eyes of fibrosis group, AMB originating from the parafoveal retinal capillary network was observed, which grew into and destroyed the integrity of the vascular arch ring at the edge of FAZ. AMB was crisscrossing and winding, and its curvature expands. B-scan images showed the blood flow signal in the subfoveal fiber nodule, and the blood flow signal traversed between the inner retina and the fiber nodule in 23 eyes (88.46%, 23/26). In the non-fibrosis group, all the vascular abnormalities were characterized by capillary dilation and defect, and no breakage of FAZ anastomotic vascular arch ring or AMB was observed.Conclusions:In Coats' disease with subfoveal fiber nodules, staggered and dilated AMBs emerge from the parafoveal vascular network, grow into and destroy the integrity of the vascular arch ring at the edge of FAZ, and grow down longitudinally into the fiber nodules.
ABSTRACT
Objective:To study the levels and variation of equilibrium factor in indoor environment.Methods:A one-year continuous measurement of radon concentration and equilibrium equivalent radon concentration was carried out in an indoor office building of Nanning city. The effective data acquisition rates of radon gas and radon progeny were 99.9% and 86.7%, respectively.Results:The annual average activity concentration and equilibrium equivalent radon concentration in indoor environment were (50.9±20.7)and (15.5±10.1)Bq/m 3, both of which had the same diurnal and seasonal variation. The average annual value of equilibrium factor was 0.30±0.12, showing no obvious diurnal variation. The distribution of monthly mean value of equilibrium factor showed a similar trend to that of radon and radon progeny. The highest and the lowest value appeared in November and June, respectively, with 0.47±0.24 and 0.19±0.06. Conclusions:Due to the large variation range of monthly mean value of equilibrium factor in indoor environment, when annual effective dose of radon exposure was estimated based on radon gas concentration, attention should be paid to choose the quantity value of equilibrium factor and the uncertainty caused by the change of equilibrium factor should be considered.

ABSTRACT
Stargardt disease (STGD) is one of the most prevalent inherited macular dystrophy, and most often occurs in child or adolescence. Irreversible vision loss is observed in almost all cases. Type 1 (STGD1) is one of the most common type. It is an autosomal recessive condition, caused by mutations in the Abca4 gene. In recent years, encouraging progress has been made in the treatment of STGD1. C20-D3-retinyl acetate (ALK- 001), fenretinide and ICR-14967 (A1120) as visual cycle modulators, StarGen as gene supplementation therapies, and the stem cell transplantation of human embryonic stem cell-derived retinal pigment epithelium cells are the most promising therapies. With the development of studies and clinical trials, the clinical application of various treatments of STGD1 are expected in the near feature, which are expected to save the vision of most patients.
ABSTRACT
Objective:Exposure to pollutants may induce aggravation of asthma in children through various ways.Ambient black carbon(BC)is a typical pollutant in Northeast China, and there has been no research report on the relationship between atmospheric BC exposure and childhood asthma in Northeast China.This study is to investigate the association between the atmospheric concentration of BC and hospital visits of daily childhood asthma.Methods:During the period of January 1 to August 31 in 2019, 52 653 hospital visits of childhood asthma children were recorded in several hospitals in Shenyang.A time series analysis was conducted to explore the relationship between the atmospheric concentration of BC and hospital visits of daily childhood asthma.Results:During the study period, the total number of children with asthma in outpatient and emergency departments in Shenyang was 52 653, the average concentration of BC was 2.58 mg/m 3.Increased concentrations of BC(2.00~10.03 mg/m 3)( RR=1.17, 95% CI: 1.07~1.28)and NO 2(0~88 μg/m 3)( RR=1.21, 95% CI: 1.06~ 1.39)were significantly associated with elevated number of childhood asthma in outpatient and emergency departments( P< 0.05). The highest cumulative effect of increased pollutants on children′s asthma within 10 days was BC( RR=1.60, 95% CI: 1.23~2.08). Conclusion:There is a positive association between BC concentration and hospital visits of childhood asthma, the accumulative effect of BC on childhood asthma is greater than other pollutants.
ABSTRACT
Purpose@#The evidence of adherence to cancer prevention guidelines and endometrial cancer (EC) risk has been limited and controversial. This study summarizes and quantifies the relationship between adherence to cancer prevention guidelines and EC risk. @*Materials and Methods@#The online databases PubMed, Web of Science, and EMBASE were searched for relevant publications up to June 2, 2020. This study had been registered at PROSPERO. The registration number is CRD42020149966. Study quality evaluation was performed based on the Newcastle-Ottawa Scale. The I2 statistic was used to estimate heterogeneity among studies. Egger’s and Begg’s tests assessed potential publication bias. Summary hazard ratios (HRs) and 95% confidence intervals (CIs) for the relationship between adherence to cancer prevention guidelines score was assigned to participants by summarizing individual scores for each lifestyle-related factor. The scores ranged from least healthy (0) to most healthy (20) and the EC risk was calculated using a randomeffects model. @*Results@#Five prospective studies (four cohort studies and one case‑cohort study) consisted of 4,470 EC cases, where 597,047 participants were included. Four studies had a low bias risk and one study had a high bias risk. Summary EC HR for the highest vs. lowest score of adherence to cancer prevention guidelines was 0.54 (95% CI, 0.40 to 0.73) and had a high heterogeneity (I2=86.1%). For the dose-response analysis, an increment of 1 significantly reduced the risk of EC by 6%. No significant publication bias was detected. @*Conclusion@#This study suggested that adherence to cancer prevention guidelines was negatively related to EC risk.
ABSTRACT
Objective:To observe and analyze the clinical features and prognosis of proliferative diabetic retinopathy (PDR) with chronic myeloid leukemia.Methods:A retrospective case series study. From May 2011 to December 2020, 5 patients (10 eyes) were included in this study in Eye-ENT Hospital of Fudan University. Basic information about the patient's age, gender, diabetes history and CML history were collected. The endocrine and hematological indexes of all patients were evaluated. All the patients were undertaken visual acuity, intraocular pressure, slit lamp and fundus examination and other examinations to observe the eye conditions. Ophthalmic treatments included panretinal laser photocoagulation, intravitreal injection of anti-vascular endothelial growth factor, vitrectomy. During the follow up period from 5 months to 6 years, prognosis was observed at each office visit. During the follow up period, patients' vision, intraocular pressure, anterior segment and retinal status were observed.Results:There were 4 males and a female in 5 patients. The ages were from 27 to 49 years, with the mean age of 39 years. All patients were bilateral. All patients suffered type 2 diabetes for 3 months to 13 years. Four of them were diagnosed as chronic myeloid leukemia before visiting to ophthalmologists, while the other visited to ophthalmology first due to poor vision. The initial visual acuity ranged from light perception to 0.4 and 6 eyes were less than 0.1. In addition to the typical manifestations of diabetic retinopathy, such as venous tortuous dilation, exudation, microaneurysm and neovascularization, patients also presented with Roth spot as leukemic fundus manifestations. All eyes developed to PDR stage. Abnormal thickening of the neovascular membranes may occur in the lower part of the retina, with secondary traction retinal detachment. All the eyes were treated with pan retinal photocoagulation and 9 eyes underwent pars plana vitrectomy. After treatment, retina of 8 eyes kept flat. The best corrected visual acuity ranged from no light perception to 1.0, and only 4 eyes reached more than 0.2. Unfortunately, one eye lost vision because of secondary neovascular glaucoma.Conclusions:PDR patients with CMLof fundus not only have venous tortuous dilation, exudation, microaneurysm and neovascularization, also present with Roth spot as leukemic fundus manifestations. Diabetic retinopathy combined with CML could progress rapidly, and its aggravating complications such as hyperplastic membrane, vitreous hemorrhage and traction retinal detachment may result in poor visual prognosis. Early screening and treatment can help improve the prognosis of patients.
ABSTRACT
Objective:To compare the outcomes of arthroscopic rotator cuff repair in patients with or without stiffness.Methods:Retrospective analysis was performed on the data of 20 patients (stiffness group) who underwent arthroscopic rotator cuff repair combined with capsular release from January 2017 to November 2019. There are 9 males and 11 females, age 62.2±8.7 years old (range 45 to 80 years old), preoperative duration 5.2±4.3 months (range 1 to 12 months). 54 patients who underwent arthroscopic rotator cuff repair without stiffness were used as the control group. There were 16 males and 38 females, aged 60.9±9.1 years old (range 46 to 81 years old), preoperative duration 8.2±13.0 months (range 1 to 60 months). Pain, function and range of motion (ROM) were recorded at 1 month, 3 months, 6 months post-operatively and last follow-up, and compared with that of pre-operatively. Satisfaction and complication were recorded at the last follow-up. The main outcome measurements included the visual analogue scale (VAS), the American Shoulder and Elbow Surgeons (ASES) score, the University of California at Los Angeles shoulder rating scale (UCLA), Constant-Murley score, and range of motion.Results:The mean follow-up period was 19.7±4.6 months (12-30 months) in the stiffness group, and 18.6±4.4 months (12-29 months) in non-stiffness group. VAS, ASES score, UCLA score, Constant-Murley score and ROM were significantly improved post-operatively. One month post-operatively, the VAS score was 4.2±1.5 in stiffness group, and 3.4±1.1 in the non-stiff group, and the difference was statistically significant between two groups ( t=2.381, P=0.020). There was no significant difference at 3 months post-operatively. The ASES score, UCLA score and Constant-Murley score were 52.3±10.2, 17.8±4.2 and 51.7±9.7 in stiffness group at 3 months post-operatively, and 57.4±7.4, 21.6±3.8, 63.2±13.5 in non-stiffness group, respectively. The difference was statistically significant ( t=2.363, P=0.021; t=3.713, P<0.001; t=3.484, P<0.001). There was no significant difference at 6 months post-operatively. The postoperative satisfaction of stiffness group and the non-stiffness group were 95.0% and 96.3%, respectively. The difference was not statistically significant ( χ2=0.2511, P=0.802). Conclusion:The results of stiffness group are statistically the same as those in non-stiffness group at last follow-up, although the recovery period is longer in patients who combined with stiffness at the first 6 months.
