This article gives an excerpt of the recommendations in this guideline.

Objective To analysis the correlations of cataract patients'age,axial length(AL)with anterior chamber depth(ACD),lens thickness(LT),and postoperative effective lens position(ELP).Methods A retrospective study was employed to analyze the biometric parameters of 7458 cataract patients(7458 eyes)who underwent surgical treatment in the First Affiliated Hospital of Kunming Medical University from January 2016 to December 2022.All measurements were obtained using the Lenstar LS900 optical biometer via optical low-coherence reflectance technology.Pearson or Spearman correlation analyses was performed between patients'age,sex,and AL with ACD,LT,and postoperative ELP measurements.Results The mean AL of patients was 23.41(22.68,24.31)mm,categorized into 4 groups:short AL group(AL≤22 mm,593 cases,8.0%),normal AL group(AL 22-24 mm,4520 cases,60.5%),longer AL group(AL 24-26 mm,1579 cases,21.2%),and long AL group(AL>26 mm,766 cases,10.3%).The ACD was(2.65±0.43)mm,and the LT was(4.29±0.46)mm.Compared with female patients,male patients had significantly longer AL,deeper ACD,and thicker LT(P<0.001).Postoperative ELPs,measured in 209 eyes 3 months after surgery,was 5.03(4.57,5.21)mm.Correlation analysis revealed a positive correlation between AL and ACD in short,normal,and longer AL groups(ρ=0.155,ρ=0.311,ρ=0.074,P<0.001 or P<0.05),while a negative correlation was found in the long AL group(ρ=-0.089,P<0.05).No statistically significant correlation was observed between AL and LT in short AL group(P>0.05),but a negative correlation was noted in normal and longer AL groups(ρ=-0.104,ρ=-0.095,P<0.001),and a positive correlation in long AL group(ρ=0.165,P<0.001).In short,normal,and longer AL groups,postoperative ELP was positively correlated with preoperative ACD(ρ=1.000,ρ=0.826,ρ=0.441,P<0.001),with no significant correlation in long AL group(P>0.05).Conclusions In cataract patients,AL,ACD,and LT are associated with both age and sex.LT and AL significantly influence ACD,while ACD and AL significantly influence LT.Preoperative ACD is the primary factor affecting postoperative ELP.

Objective To investigate the correlation of corneal α angle and κ angle with lens tilt in normal human eyes using a new swept-source optical biometer.Methods A cross-sectional study was conducted,involving 303 healthy eyes(148 right eyes and 155 left eyes)of patients who visited the First Affiliated Hospital of Kunming Medical University from June to August 2024.ZW-30 swept-source optical biometer was used to collect the lens tilt angle,κ angle(distance from the corneal light reflex to the pupil center),and α angle(distance from corneal light reflex to the corneal geometric center,which is the midpoint of the horizontal white to white(WTW)diameter).The degrees(°)and directions of κ angle and α angle were calculated by the ratio of the above measurements to the anterior chamber depth(ACD)respectively.Spearman correlation analysis and linear regression analysis were employed to evaluate the correlations between the magnitude and direction of corneal α angle,κ angle and lens tilt angle.Results The magnitude and direction of corneal α angle,κ angle,and lens tilt angle in the right eye were as follows respectively:(0.54±0.19)mm(7.81°±3.88°),194.43°±39.75°;(0.27±0.23)mm(4.72°±3.90°),181.07°±79.59°;5.52°±1.67°,188.21°±25.73°.For the left eye,the corresponding values were:(0.47±0.27)mm(8.12°±5.26°),336.04°±46.64°;(0.26±0.27)mm(4.45°±4.80°),322.86°±107.79°;5.50°±1.61°,340.65°±32.84°.Spearman's correlation analysis showed that the correlation coefficients between corneal α angle and lens tilt angle in the right eye were 0.609(distance correlation)and 0.625(angle correlation),while those for κ angle were 0.559(distance correlation)and 0.578(angle correlation).In the left eye,the correlation coefficients between corneal α angle and lens tilt angle were 0.545(distance correlation)and 0.552(angle correlation),and those for κ angle were 0.377(distance correlation)and 0.395(angle correlation).In addition,the correlation coefficient between the direction of corneal α angle and the direction of lens tilt angle in the right eye was 0.343,and that for κ angle direction was 0.284;in the left eye,the correlation coefficients were 0.216(α angle direction)and 0.198(κ angle direction),all with statistical significance(P<0.05).Univariate linear regression analysis showed that lens tilt was positively correlated with both corneal α angle and Kappa angle(P<0.05).Conclusions Corneal α angle and κ angle are highly correlated with lens tilt angle in both eyes,and the correlation of corneal α angle is stronger than that of κ angle in both left and right eyes.The correlation expressed by degree(°)is better than that by distance(mm).It is recommended to refer to the corneal α angle and κ angle expressed in degrees during preoperative evaluation.

Objective:To clarify the spatio-temporal characteristics and changing trends of provincial health resources and medical pressure,and to provide suggestions for the high-quality development of medical and health services in China.Methods:Based on the panel data of 31 provincial administrative units from 2010 to 2020,a comprehensive evaluation system of provincial health resources and medical pressure was constructed.The global entropy method and exploratory spatial analysis were used to reveal the spatio-temporal differentiation and correlation pattern,and the Tapio decoupling index was illustrated to explain the evolution characteristics and trends.Results:During the observation period,health resources and medical pressure in the vast majority of provinces in China rose steadily,with positive spatial correlation and agglomeration,and a close relationship with economic development and population demand;the mainstream decoupling state of the country shifted from a negative decoupling to a positive decoupling,with an obvious progressive decoupling trend,and the development of regional health continued to improve.Conclusions and suggestions:Provinces need to take into account the status quo of health development in their own provinces,focus on the spatio-temporal coupling of elements and structures,and optimize the structure of health resource allocation and enhance the resilience of the health system as a means of bringing into play the comparative advantages of the regional health system.

Objective To explore the changes in macrophage infiltration behavior during the dynamic evolution of thrombi following the formation of acute carotid artery thrombosis occlusion(ACTO).Methods 15 healthy male New Zealand rabbits were selected to establish an ACTO model by causing injury to the rabbit carotid artery using surgical sutures treated with ferric chloride.All rabbits were randomly divided into 5 groups according to the end-point time using the random number table method,namely 24-hour group,1 week group,4week group,8 week group,and 12week group postoperatively,with 3 rabbits in each group.At 24 hours post-operation,the ACTO model was examined by DS A.At 24 hours,1 week,4 weeks,8 weeks,and 12 weeks post-operation,samples were taken from the thrombotic arterial segment of the 3 rabbits in each group and embedded in paraffin.The thrombus samples were stained with hematoxylin-eosin(HE)and Martius scarlet blue(MSB)to analyze changes in thrombus morphology and composition(including red blood cells,fibrin and collagen fibers).Orbit Imaging Analysis software was used for semi-quantitative analysis of the thrombus composition components.Using immunohistochemistry to detect the distribution of MO and M2 macrophages in thrombi,aimed to summarize the dynamic evolution of thrombus morphology,composition,and macrophage infiltration behavior at different stages following ACTO occurrence.Results The 24-hour DSA results indicated that all experimental rabbits successfully established the ACTO model.(1)HE staining showed a continuous increase in thrombus size from 24 hours to 1 week.By 4 weeks,signs of thrombus dissolution appeared,and at 8 weeks,neovascularization was observed within the thrombus.By 12 weeks,signs of fibrosis were evident in the thrombus.(2)MSB staining revealed that during the acute phase of thrombus formation(within 24 hours after surgery),red blood cells were the predominant component initially,but after this period,fibrin and collagen fibers became the main components.(3)The detection results of MO macrophages showed that 24 hours after surgery,MO macrophages in the thrombus were not evenly distributed throughout the thrombus,but mainly gathered at the thrombus edge;at 1 week after surgery,the positive area percentage of MO macrophage in the thrombus increased compared with 24 hours after surgery(thrombus edge:[41.7±27.0]％vs.[24.6±16.7]％,thrombus core:[35.7±19.6]％vs.[11.1±10.4]％,all P＜0.001),and evenly distributed within the thrombus;at 4 weeks after surgery,MO macrophages in the thrombus decreased compared with 1 week after surgery(thrombosis edge:[10.7±6.1]％vs.[41.7±27.0]％,thrombus core:[12.1±8.5]％vs.[35.7±19.6]％,all P＜0.001),the differences were statistically significant.At 4,8,and 12 weeks after surgery,MO macrophages within the thrombus did not change significantly with time(thrombus edge:[10.7±6.1]％,[8.0±7.7]％,and[8.9±5.3]％;thrombus core:[12.1±8.5]％,[9.5±4.2]％,and[15.7±11.0]％),and the differences were not statistically significant(all P＞0.05).In addition,at 12 weeks after surgery,MO macrophages at the thrombus edge was less than the thrombus core([8.9+5.3]％vs.[15.7±11.0]％,P＜0.01).The detection results of M2 macrophages showed that 24 hours after surgery,M2 macrophages in the thrombus were widely distributed throughout the thrombus;at 1 week after surgery,the positive area percentage of M2 macrophages in the thrombus increased compared with 24 hours after surgery(thrombus edge:[22.1±11.3]％vs.[11.4±8.7]％,P＜0.001;thrombus core:[24.5±9.8]％vs.[7.6±6.0]％,P＜0.001);at 4 weeks after surgery,M2 macrophage in the thrombus decreased compared with 1 week after surgery(thrombosis edge:[10.6±3.7]％vs.[22.1±11.3]％,P＜0.001;thrombus core:[9.2±4.3]％vs.[24.5±9.8]％,P＜0.001);at 8 weeks after surgery,M2 macrophages in the thrombus increased compared with 4 weeks after surgery([17.9±8.8]％vs.[9.2±4.3]％,P＜0.001),and the differences were statistically significant.However,M2 macrophages in the thrombus did not change significantly from 8 weeks to 12 weeks after surgery(thrombus edge:[9.4±6.3]％vs.[8.5±5.3]％,P＞0.05;thrombus core:[17.9±8.8]％vs.[14.4±10.0]％,P＞0.05).In addition,at 8 and 12 weeks after surgery,M2 macrophages in the thrombus core was greater than the thrombus edge(8 weeks after surgery:[17.9±8.8]％vs.[9.4±6.3]％,P＜0.001;12weeks after surgery:[14.4±10.0]％vs.[8.5±5.3]％,P＜0.001).Conclusions This study successfully established an ACTO animal model and demonstrated for the first time the dynamic evolution of macrophages within 12 weeks post-thrombus formation.Macrophages may played a significant role in both thrombus formation and fibrinolysis,as well as in the promotion of thrombus dissolution and the formation of new blood vessels within the thrombus which may potentially promote the spontaneous reperfusion of the occluded vessels.The results of this study need further verification.

Objective:To investigate clinical, immunoserological, and therapeutic characteristics of patients with linear IgA bullous dermatosis (LABD) .Methods:Clinical data were collected from patients with LABD in Hospital of Dermatology, Chinese Academy of Medical Sciences from 2016 to 2023, and their clinical, immunoserological, and therapeutic characteristics were retrospectively analyzed.Results:Twenty-six patients were included, comprising 12 males and 14 females, with a median age ( Q1, Q3) of 32 (11, 48) years. Among the 26 patients, 12 (46.2%) presented with annular erythema and blisters, while 14 (53.8%) with atypical lesions (erythema and blisters not in an annular arrangement). Direct immunofluorescence assay yielded positive results in 14 out of 19 patients (73.7%). Indirect immunofluorescence on salt-split skin showed IgA with or without IgG deposited in the epidermis of the salt-split skin in 53.8% (14/26) of the patients. The positive rate of IgA antibody detected by Western blot analysis was 88.5% (23/26). Western blot analysis with epidermal extracts as substrates showed that 18 patients (69.2%) had serum IgA recognizing the linear IgA bullous dermatosis autoantigen LAD-1 with a relative molecular weight of 120 000, of whom 4 (15.4%) also had IgA recognizing BP180; in 1 case (3.8%), the serum IgA could recognize a protein with a relative molecular weight of about 170 000 in the epidermal extracts; another 1 (3.8%) had IgA recognizing BP230 and a protein with a relative molecular weight of 140 000 in the epidermal extracts at the same time; additionally, the serum IgA recognizing type Ⅶ collagen with a relative molecular weight of 290 000 in the dermal extracts was detected in 1 case (3.8%). Among 23 patients receiving dapsone treatment, 21 well responded, 1 showed poor response, and 1 was intolerant; in addition, the latter two patients could not achieve complete remission by tofacitinib. Minocycline, colchicine, and sulfasalazine were effective in another 3 patients. Conclusions:In this study, LABD mainly occurred in middle-age individuals, and LAD-1 was determined to be a major autoantigen. Western blot analysis showed an increased positive rate of IgA antibody compared with immunofluorescence assay, and could be an important means of differential diagnosis. Although the LABD patients responded well to dapsone, it is still necessary to explore other safe and effective medications.

Objective:To analyze clinical, immunoserological, and therapeutic features of patients with anti-p200 pemphigoid.Methods:Clinical data were collected from patients with confirmed anti-p200 pemphigoid at the Hospital of Dermatology, Chinese Academy of Medical Sciences from January 2015 to February 2024. Their clinical, immunoserological, and therapeutic characteristics were retrospectively analyzed.Results:A total of 35 patients were included, with a male-to-female ratio of 2.5∶1 (25 males and 10 females) and ages of 57.74 ± 17.12 years. Two (5.71%) patients were accompanied by psoriasis. In these patients, anti-p200 pemphigoid exhibited heterogeneous clinical phenotypes, mimicking classic bullous pemphigoid (20 cases, 57.14%), linear IgA bullous dermatosis (8 cases, 22.86%), or eczema (4 cases, 11.43%). The positive rates of direct immunofluorescence (DIF), indirect immunofluorescence on salt-split skin (ss-IIF), Western blot analysis with dermal extracts as substrates, and Western blot analysis with laminin γ1 C-terminal region (Lnγ1C) as substrates were 100% (24/24), 82.86% (29/35), 100% (35/35), and 80.64% (25/31), respectively. Among the 35 patients, treatment and follow-up information was available for analysis in 33. Six patients (18.18%) received non-glucocorticoid systemic therapy and topical glucocorticoid therapy, with a follow-up period ( M [ Q1, Q3]) of 19.50 (6.50, 69.25) months, and 1 withdrew the drugs. Sixteen patients received systemic glucocorticoids combined with traditional anti-inflammatory drugs, with a follow-up period of 13.50 (4.25, 18.00) months, the initial dose of glucocorticoids was equivalent to 0.30 - 0.50 mg·kg -1·d -1 of prednisone, and the time to disease control was 15.31 ± 5.23 days; among the 16 patients, 3 experienced fluctuations in disease condition which were alleviated by adding dapsone, and 1 discontinued glucocorticoids. Five patients (15.15%) received systemic glucocorticoids combined with immunosuppressants, with a follow-up period of 26.00 (14.00, 90.00) months, the initial dose of glucocorticoids was equivalent to 0.50 - 0.75 mg·kg -1·d -1 of prednisone, and the time to disease control was 10.20 ± 3.27 days; among the 5 patients, 2 received maintenance treatment with glucocorticoids (5 - 10 mg/d prednisone), 2 withdrew the drugs, and 1 relapsed after discontinuing glucocorticoids. One patient (3.03%) received systemic glucocorticoids combined with rituximab therapy, with a follow-up period of 53 months, and discontinued glucocorticoids thereafter. One patient (3.03%) received systemic glucocorticoids combined with dupilumab therapy, which proved to be effective. Four patients (12.12%) received systemic glucocorticoids combined with Janus kinase inhibitors, and 3 responded well. Conclusions:Anti-p200 pemphigoid presented a heterogeneous clinical profile in this series of patients, but scarring and milia were rare. Some patients showed negative results in Western blot analysis with Lnγ1C as substrates. The prognosis of anti-p200 pemphigoid was usually favorable, and most patients could achieve complete remission and ultimately discontinue medication.

Objective:To analyze clinical and immunoserological features of patients with epidermolysis bullosa acquisita (EBA) .Methods:Clinical data were collected from patients with confirmed EBA at the Hospital of Dermatology, Chinese Academy of Medical Sciences from January 2017 to January 2022, and their clinical and immunoserological characteristics were retrospectively analyzed.Results:A total of 20 patients were collected, including 7 males and 13 females, and they were aged 41.85 ± 18.43 years. Ten patients presented with the classical phenotype of EBA, 8 with the inflammatory phenotype of EBA, and 2 with the mixed phenotype of EBA. Mucosal involvement occurred in 19 cases, nail involvement occurred in 4, scarring was observed in 9, and milia in 13. Indirect immunofluorescence on salt-split skin showed IgG deposition on the dermal side in 19 cases. Enzyme-linked immunosorbent assay for type Ⅶ collagen revealed positive results in 19 cases, with a diagnostic sensitivity of 95%. Western blot analysis with dermal extracts as substrates revealed a protein band with a relative molecular mass of 290 000 in 16 cases, with a diagnostic sensitivity of 80%, and multiple autoantibodies against different basement membrane zone antigens were identified in 3 cases. Fifteen patients received systemic glucocorticoids, including 2 receiving combined immunosuppressive agents and 13 receiving combined anti-inflammatory agents with dapsone and colchicine as the first and second commonly used anti-inflammatory agents respectively; among 5 patients receiving non-glucocorticoid therapy, 2 with inflammatory EBA were sensitive to dapsone and colchicine, while the other 3 patients were lost to follow-up. Totally, 17 patients were followed up for an average duration of 26.21 months. Among the 17 patients, 1 achieved complete remission off therapy, 2 achieved complete remission on minimal therapy, and the remaining 14 patients achieved partial remission.Conclusions:The treatment of EBA is challenging, and anti-inflammatory agents such as dapsone and colchicine are often used. Immunoserological tests are of great value in the diagnosis of EBA.

Epstein-Barr virus (EBV) associated post-transplant lymphoproliferative disorders (PTLD) are one of the most severe complications after hematopoietic stem cell transplantation (HSCT). This study includes 31 cases of aplastic anemia (AA) patients who developed PTLD after haploidentical transplantation, summarizing their clinical characteristics and categorizing them into either rituximab monotherapy group or combination therapy group based on whether their condition improved by 1 log after a single dose of rituximab. The incidence of PTLD after HSCT in children with AA was 10.16%, and the incidence of PTLD in patients with age >10 years was significantly increased ( χ2=11.336, P=0.010). Of the 31 patients, 27 were clinically diagnosed and 4 were pathologically confirmed. Finally, 15 patients were classified into the rituximab treatment group and 15 patients into the combination treatment groups. Finally three patients died, and the 2-year overall survival rate was (89.7±5.6) %. Standard pre-treatment protocols and EBV reactivation are risk factors affecting the prognosis of PTLD. There was no statistically significant difference in the impact of the two treatment schemes on prognosis.
