Objective To investigate the detection rate and grading diagnostic value of ultra-wide field swept-source optical coherence tomography angiography(UWF SS-OCTA)combined with ultra-wide field scanning laser ophthalmoscopy(UWF SLO)in diabetic retinopathy(DR)lesions.Methods In this cross-sectional study,diabetic patients attending the Ophthalmology Department of Sichuan Provincial Peoples Hospital were recruited.All participants underwent UWF SS-OC-TA,UWF SLO and fundus fluorescein angiography to detect DR lesions,including microaneurysms(MA),intraretinal hem-orrhages(IRH),nonperfusion areas(NPAs),intraretinal microvascular abnormalities(IRMAs),venous beading(VB),neovascularization elsewhere(NVE),neovascularization of the optic disc(NVD),and vitreous hemorrhage(VH).The re-sults of the combination of three imaging examinations(triple imaging)were used as the standards,evaluating the detec-tion rate and severity grading consistency in DR lesions of pairwise combinations of different imaging modalities.Results A total of 101 patients(175 eyes)were included.Compared with the triple imaging results,the detection rates of UWF SS-OCTA combined with UWF SLO for MA,IRH,NPAs,IRMAs,NVE,NVD and VH were 91％,83％,77％,69％,27％,10％and 12％,respectively,with Kappa values of 0.812,1.000,1.000,1.000,0.986,0.970 and 1.000.Compared with the triple imaging results,the combination of UWF SS-OCTA and UWF SLO demonstrated excellent consistency in grading the severity of DR(Kappa=0.943).Conclusion UWF SS-OCTA combined with UWF SLO can accurately identify MA,IRH,NPAs,IRMAs,NVE,NVD and VH,demonstrating high accuracy in DR screening and grading diagnosis,making it suitable for large-scale screening and management of DR in clinical practice.

Morita therapy has been bom for more than 100 years.Inpatient Morita therapy is highly oper-able and easy to master.It can improve many refractory neuroses through four-stage treatment.But more neuroses are treated in outpatient clinics,and Morita therapy cannot be used in hospitalized patients.Therefore,the formula-tion of expert opinions on outpatient operations is particularly important.This paper is based on domestic and for-eign references,and after many discussions by domestic Morita therapy experts,and then drew up the first version of the expert opinions on operation of outpatient Morita therapy.Meanwhile the operation rule of Morita therapy in three stages of outpatient treatment was formulated:in the etiological analysis stage,under the theoretical guidance of Morita therapy,analyze the pathogenic factors,to improve treatment compliance and reduce resistance;during the operating stage,guide patients to engage in constructive and meaningful actions,realizing the achievement of letting nature take its course principle;in the cultivating character and enriching life stage,pay attention to positive infor-mation,expanding the scope and content of actions,improving the ability to adapt to complex life,and preventing recurrence caused by insufficient abilities.It will lay a foundation for the promotion of Morita therapy in domestic outpatient clinics,so that more patients with neurosis and other psychological diseases could receive characteristic Morita therapy treatment in outpatient clinics.

Objective:To investigate the relationship between the number of removed lymph nodes(RLN)and patient prognosis during radical surgery for extensive cervical cancer(CC).Methods:Clinical data of 21416 pa-tients with CC who underwent radical hysterectomy between January 1,2004 to August 31,2018 in the Chinese Cervical Cancer Clinical Study was retrospectively reviewed.Restricted cubic spline(RCS)was used to analyze the dose-response relationship between the number of RLN and prognosis.The patients were divided into three groups according to the RCS and RLN number:1-17 group(8733 cases),18-26 group(8189 cases),and≥ 27 group(4494 cases).Kaplan-Meier survival analysis and Log-Rank tests were used to compare the OS rates and DFS rates between groups at 3 and 5 years.Multivariate Cox proportional hazards model was used to analyze the prognostic mortality risk.Results:① RCS results showed a U-shaped nonlinear dose-response relationship be-tween the number of RLN and prognosis(P＜0.01).When the number of RLN was less than 26,the risk of death decreased as the number of RLN increased,and the risk was lowest when the number of RLN was 26.②There were statistically significant differences(P＜0.05)in age,histological type,tumor diameter,nerve invasion,uterine invasion,vaso-lymph node space invasion,cervical invasion,number of lymph node metastasis,whether preopera-tive adjuvant therapy was received,postoperative adjuvant therapy,and whether postoperative adjuvant therapy was standardized among the 3 groups(P＜0.05).③Kaplan-Meier survival curve analysis showed that the 5-year OS of the 1-17 group,18-26 group,and ≥ 27 group were 90.23％,92.28％,and 91.61％,respectively,and the 5-year DFS were 85.32％,87.90％,and 87.18％,respectively.The differences between the three groups were sta-tistically significant(P＜0.01).④The results of multivariate Cox regression analysis showed that RLN number in the range of 1-17 was a significant risk factor for the 3-and 5-year OS and DFS,when compared to the 18-26 RLN group(HR＞1,P＜0.05).Conclusions:RLN number may be one of the prognostic indicators of CC.When the number of RLNs is between 18-26,the prognosis of the patient may be better.The number of RLN in the range of 1-17 may increase the risk of recurrence or death in CC patients.

Objective:To investigate the impact of lifestyle, apolipoprotein E (ApoE) gene, and their interaction on the risk for cognitive frailty in the elderly population in China.Methods:The study participants were from the Chinese Longitudinal Healthy Longevity Survey. The information about their lifestyles were collected by questionnaire survey, and a weighted lifestyle score was constructed based on β coefficients associated with specific lifestyles to assess the combined lifestyle. ApoE genotypes were assessed by rs429358 and rs7412 single nucleotide polymorphisms. Cognitive frailty was assessed based on cognitive function and physical frailty. Cox proportional hazards regression model was used to analyze the association of lifestyle and ApoE gene with the risk for cognitive frailty and evaluate the multiplicative and additive interactions between lifestyle and ApoE gene. Results:A total of 5 676 elderly persons, with median age [ M ( Q1, Q3)] of 76 (68, 85) years, were included, in whom 615 had cognitive frailty. The analysis by Cox proportional hazards regression model indicated that moderate and high levels of dietary diversity could reduce the risk for cognitive frailty by 18% [hazard ratio ( HR)=0.82, 95% CI: 0.68-1.00] and 28% ( HR=0.72, 95% CI: 0.57-0.91), respectively; moderate and high levels of physical activity could reduce the risk by 31% ( HR=0.69, 95% CI: 0.56-0.85) and 23% ( HR=0.77, 95% CI: 0.64-0.93), respectively. Healthy lifestyle was associated with a 40% reduced risk for cognitive frailty ( HR=0.60, 95% CI: 0.46-0.78). ApoE ε4 allele was associated with a 26% increased risk for cognitive frailty ( HR=1.26, 95% CI: 1.02-1.56). No multiplicative or additive interactions were found between lifestyle and ApoE gene. Conclusions:Dietary diversity and regular physical activity have protective effects against cognitive frailty in elderly population. Healthy lifestyle can reduce the risk for cognitive frailty in elderly population regardless of ApoE ε4 allele carriage status.

Objective Aberrant expression of ATP binding cassette subfamily B member 1(ABCB1)plays a key role in several cancers.However,influence of G protein coupled receptor family C group 5 type A(GPRC5A)-regulated ABCB1 expression on lung adenocarcinoma proliferation remains unclear.Therefore,this study investigated the effect of GPRC5A regulated ABCB1 expression on the proliferation of lung adenocarcinoma. Methods ABCB1 expressions in lung adenocarcinoma cell lines,human lung adenocarcinoma tissues,and tracheal epithelial cells and lung tissues of GPRC5A knockout mice and wild-type mice were analyzed with RT-PCR,Western blot,or immunohistochemical analysis.Cell counting kit-8 assay was performed to analyze the sensitivity of tracheal epithelial cells from GPRC5A knockout mice to chemotherapeutic agents.Subcutaneous tumor formation assay was performed to confirm whether down-regulation of ABCB 1 could inhibit the proliferation of lung adenocarcinoma in vivo.To verify the potential regulatory relationship between GPRC5A and ABCB1,immunofluorescence and immunoprecipitation assays were performed. Results ABCB1 expression was up-regulated in lung adenocarcinoma cell lines and human lung adenocarcinoma tissues.ABCB1 expression in the tracheal epithelial cells and lung tissues of GPRC5A deficient mice was higher than that in the wild type mice.Tracheal epithelial cells of GPRC5A knockout mice were much more sensitive to tariquidar and doxorubicin than those of GPRC5A wild type mice.Accordingly,28 days after injection of the transplanted cells,the volume and weight of lung tumor in ABCB1 knockout cell-transplanted GPRC5A-/-C57BL/6 mice were significantly smaller than those in wild type cell-transplanted mice(P=0.0043,P=0.0060).Furthermore,immunofluorescence and immunoprecipitation assays showed that GPRC5A regulated ABCB1 expression by direct binding. Conclusion GPRC5A reduces lung adenocarcinoma proliferation via inhibiting ABCB1 expression.The pathway by which GPRC5A regulates ABCB1 expression needs to be investigated.
