AIM: To assess the effectiveness of selective laser trabeculoplasty(SLT)in the treatment of primary open angle glaucoma(POAG).METHODS:Totally 24 patients(33 eyes)with POAG who had poor control of intraocular pressure(IOP)from June 2022 to December 2023 were included in this retrospective study, and all of them were treated with SLT. Furthermore, the IOP, mean deviation(MD), mean sensitivity(MS), and the thickness and vascular density(VD)of optic disc nerve layer were compared after treatment. RESULTS: There were significant reducion in IOP at 1, 3, 6, 12 mo after treatment(all P<0.001). There were no statistically significant differences in MD and MS before treatment and at 6 and 12 mo after treatment(all P>0.05), and there were no statistical significant differences in the thickness and VD of optic disc(all P>0.05).CONCLUSION: SLT can significantly reduce IOP in POAG patients in the short term, without damaging the visual field and optic disc nerves, while the effectiveness of SLT decreases over time.

Viral myocarditis is a myocardial disease resulting from various viral infections.Due to the com-plexity of its pathogenesis,effective prevention and treatment options are currently lacking.Establishing appropriate ex-perimental models is crucial for studying the pathogenic mechanisms,disease progression,early diagnosis,and the devel-opment of new drugs and therapies for viral myocarditis.This article reviews the construction methods,research advance-ments,and applications of common experimental models of viral myocarditis,which range from cell models to small ani-mal models,including mice,hamsters,and rabbits,as well as larger animals such as pigs and non-human primates.Ad-ditionally,we summarize and discuss future research directions,providing a theoretical foundation and technological guid-ance for the prevention and treatment of viral myocarditis in clinical settings.

ObjectiveTo study the correlation between the content of active ingredients of Aurantii Fructus in different main production areas and soil factors， so as to provide a theoretical basis for implementing ecological regulation of soil， improving the quality of Aurantii Fructus， and revealing the origin of genuine medicinal materials. MethodThe content of naringin， neohesperidin， total flavonoids， volatile oil， total nitrogen， total phosphorus， total potassium， and 17 soil factor-related indicators in 25 batches of Aurantii Fructus from different production areas were determined. The main soil factors affecting the content of active ingredients of Aurantii Fructus were analyzed by Pearson correlation analysis， principal component analysis， and grey correlation analysis. ResultThe pH value of the soil is between 4.83 and 8.21， and the soil is weakly acidic and neutral in general. Soil fertility exceeds the average. Pearson correlation analysis shows that the soil factors most related to the four active ingredients of Aurantii Fructus are total phosphorus， available copper， available zinc， exchangeable magnesium， available sulfur， available phosphorus， and available molybdenum. Principal component analysis shows that total nitrogen， alkali-hydrolyzable nitrogen， organic matter， available phosphorus， and available zinc are the main characteristic factors in soil. Grey correlation analysis shows that the main soil factors affecting the active ingredients of Aurantii Fructus are total phosphorus， total nitrogen， available zinc， available copper， exchangeable magnesium， and pH. ConclusionIn the cultivation of Aurantii Fructus， the medicinal material quality of Aurantii Fructus could be improved by adjusting the level of beneficial factors in the soil and improving the soil texture.

ObjectiveTo analyze the characteristics and changing trend of injury cause of mortality of residents in Qingpu District from 2002 to 2020， and to provide scientific reference for formulating regional prevention and control measures. MethodsThe injury mortality data of the registered residents in Qingpu District from 2002 to 2020 were collected. The indicators such as crude mortality rate， standardized mortality rate， and the ranking of causes of death were calculated. ResultsFrom 2002 to 2020， the average annual crude mortality rate was 50.27/100 000， the age-standardized mortality rate based on the world standard population（ASRW） was 30.08/100 000， and the age-standardized mortality rate based on the 2010 Chinese census（ASMRC） was 35.58/100 000. The average annual crude mortality rate of males was higher than that of females ［Z=54.402， Mantel-Hanszel χ²=1 742.509， P<0.01）. The overall injury mortality rate showed a downward trend with an average annual percent change（AAPC）of -4.07% （95%CI： -5.23%‒-2.90%）， P<0.001］. The top four causes of injury death were transportation accident， indeliberate fall， drowning， and suicide. The leading causes of death in 0‒ years old， 15‒ years old and ≥65 years old were drowning， transportation accident and indeliberate fall， respectively. The ASRW of transportation accident， drowning and suicide all showed a decreasing trend， and the AAPC were -8.22% （95%CI： -10.16%‒-6.24%）， -6.99% （95%CI： -9.68%‒-4.22%） and -6.21% （95%CI： -9.38%‒-2.94%）， respectively. ConclusionThe injury death rate of residents in Qingpu District shows a decreasing trend， and the distribution characteristics of injury death are different among different genders and age groups. Corresponding prevention and control strategies should be adopted for different populations.

ObjectiveTo analyze the trends in life expectancy and cause-eliminated life expectancy of the registered residents in Qingpu District, Shanghai from 2002 to 2021, and to identify the major diseases causing life expectancy loss in the area, so as to provide a theoretical basis for strengthening disease prevention and interventions and optimizing health resources allocation. MethodsUsing the International Classification of Diseases (ICD)-10 classification of death causes, average life expectancy and cause-eliminated life expectancy were calculated with the abbreviated life table and the cause-eliminated life expectancy table. A trend forecast of life expectancy from 2022 to 2029 was made. ResultsFrom 2002 to 2021, the life expectancy of Qingpu District residents showed an increasing trend, with an average annual growth of 0.32 years (AAPC=0.39%, P<0.001). Among the seven major causes of death, the cause-eliminated expected life expectancy for circulatory system diseases showed the most significant upward trend (AAPC=0.53%, P<0.001), rising from the third leading cause of death in 2002 to the first in 2021. The life expectancy loss rate due to circulatory system diseases increased from 3.79% to 7.97%. Respiratory system diseases showed the largest decline, decreasing from the first leading cause of death in 2002 to the fourth in 2021, with the life expectancy loss rate decreasing from 6.83% to 0.99%. ConclusionLife expectancy of the registered residents in Qingpu District has reached a leading level in China. Future efforts should focus on effectively increasing the life expectancy of male residents, strengthening the comprehensive prevention and treatment of chronic diseases such as cerebrovascular diseases, diabetes, and malignant tumors, and improving health promotion policies for residents to achieve a steady long-term increase in regional life expectancy.

Purpose To investigate the clinicopathological characteristics,diagnosis,and differential diagnosis of invasive mucinous adenocarcinoma(IMA)and mixed invasive mucinous and non-mucinous adenocarcinoma(mIMA).Methods The clinical data were collected in 36 patients with primary IMA and 17 patients with mIMA,and the expression of TTF-1,CK7,CK20,SATB2,CDX2,EGFR,HNF4a,etc.was detected by immunohistochemical EnVision two-step method.The Sanger se-quencing and the FISH were used for KRAS mutation and NRG1 gene rearrangement detection.The clinicopathological character-istics were analyzed with review of relevant literature.Results There were 9 cases(25.0％)and 3(8.3％)cases of papillary and micropapillary structures in IMA,while 13 cases(76.5％)(P＜0.001)and 9 cases(52.9％)(P=0.001)were present in mIMA.There were 5 cases(13.9％)of high nuclear grade of IMA and 10 cases(58.8％)of high nuclear grade of mIMA(P=0.002).TTF-1 had a positive rate of 37.5％in IMA,but 60.0％and 80.0％in the mucinous adenocarcinoma and non-mucinous adenocarcinoma components of mIMA(P=0.021),respectively.The positive rates of CK7,CK20,and CDX2 in IMA were 90.6％,21.9％,and 9.4％,and the positive rates in mucinous adenocarcinoma and non-mucinous adenocarcinoma components of mIMA were 100％,20％,20％and 100％,6.7％,6.7％,respectively and no SATB2 expression was found in all cases.There was no significant difference in the expres-sion of total EGFR and two EGFR mutation-specific antibodies(L858R,DEL19)between IMA and mIMA.There were 3 cases of mucinous adenocarcinoma with L858R positive in mIMA,and 2 of them were negative for non-mueinous adenocarcinoma.In another case,the non-mueinous adenocarcinoma component of mIMA expressed DEL19,but the mucinous adenocarcinoma component was not expressed.The positive rate of HNF4a in IMA was 72.0％(18/25),and those of HNF4a in mucinous adenocarcinoma and non-mucinous adenocarcinoma in mIMA were 41.7％(5/12)and 33.3％(4/12),respectively(P=0.048).KRAS gene sequencing was carried out in 19 cases of IMA,among which 9 cases(47.4％)had mutations,G12D and G12V were most commonly detected,and 4 cases of mIMA were sequenced,but none of them showed KRAS mutations.FISH detection showed that 2 cases(7.1％)IMAs had NRG1 translocation rearrangement.Conclusion Pulmonary mIMA is more aggressive than IMA.For example,mIMA has significantly more papillary structure,micropapillary structure,and high nu-clear grade cases than IMA.The differences in immunohisto-chemical expression and KRAS mutation between the two are sta-tistically significant.

Objective:To investigate the influence of polycystic ovary syndrome (PCOS) patients with different body mass index (BMI) on perinatal and neonatal outcomes of frozen-thawed embryo transfer.Methods:A retrospective cohort study was performed on the clinical data of patients with PCOS infertility who underwent cryopreservation transplantation in Reproductive Center of the First Affiliated Hospital of Anhui Medical University from 2016 to 2020. The clinical pregnancy was singleton, a total of 1 481 cycles were divided into 4 groups according to BMI value. There were 75 cycles in the underweight group (BMI<18.5 kg/m 2), 793 cycles in the normal weight group (18.5 kg/m 2≤BMI<24.0 kg/m 2), 468 cycles in the overweight group (24.0 kg/m 2≤BMI<28.0 kg/m 2), 145 cycles in the obese group (BMI≥28.0 kg/m 2). The differences of general information, perinatal outcome and neonatal outcome were compared among the four groups. Results:Compared with the overweight group, the normal weight group and the underweight group, the obesity group had the highest early abortion rate [23.4% (34/145) vs. 15.8% (74/468) vs. 14.0% (111/793) vs. 9.3% (7/75), P=0.014], and the lowest live birth rate [68.3% (99/145) vs. 76.7% (359/468) vs. 79.7% (632/793) vs. 88.0% (66/75), P=0.003]. The incidence of gestational diabetes in the obesity group and the overweight group [6.9% (10/145) and 4.5% (21/468)] was higher than that in the normal weight group [2.3% (18/793)] (the obesity group vs. the normal weight group P=0.005, the overweight group vs. the normal weight group P=0.028). The rate of cesarean section in the obesity group and the overweight group [81.8% (81/99), 74.9% (269/359)] was higher than that in the normal weight group [67.6% (427/632)] and the underweight group [57.6% (38/66), the obesity group vs. the normal weight group P=0.005, the obesity group vs. the underweight group P=0.001, the overweight group vs. the normal weight group P=0.015, the overweight group vs. the underweight group P=0.004]. The macrosomia birth rate [18.2% (18/99), 15.6% (56/359)] was also higher than that of the normal weight group [10.1% (64/632)] and the underweight group [6.1% (4/66), the obesity group vs. the normal weight group P=0.018, the obesity group vs. the underweight group P=0.025, the overweight group vs. the normal weight group P=0.011, the overweight group vs. the underweight group P=0.041]. There were no significant differences in late abortion rate, gestational hypertension, ectopic pregnancy and premature birth rate, Apgar score, height and birth defects (all P>0.05). Conclusion:Obesity and overweight affect the perinatal outcomes and neonatal outcomes in patients with PCOS. In clinical work, attention should be paid to the weight management of PCOS patients.

Objective:To analyze the risk factors of stress perception in patients with systemic lupus erythematosus (SLE) , and construct and validate a risk prediction model for health risk stress perception in SLE patients.Methods:This study is a cross-sectional study. From October 2020 to March 2021, totals of 310 SLE inpatients and outpatients in the Department of Rheumatology and Immunology from 4 general hospitals in Anhui Province were selected as the modeling object. According to the patients' stress perception score, they were divided into the group with health risk stress ( n=132) and the group without health risk stress ( n=178) . The general data, SLE disease activity, general self-efficacy, emotional intelligence, resilience, sleep disturbance, anxiety, depression were compared between the two groups, and independent risk factors were screened out and Logistic regression was used to construct a risk prediction model. Hosmer-Lemeshow and receiver operator characteristic curve (ROC) area were used to test the fit and prediction effect of the model, respectively, and 206 patients were included for model validation. Results:Binary Logistic regression analysis showed that SLE disease activity, resilience, anxiety, payment type, and family monthly income were the influencing factors of stress perception in SLE patients, and the difference was statistically significant ( P<0.05) . Hosmer-Lemeshow fit test showed χ 2=6.123, P=0.633. Besides, the area under the ROC, maximum Youden index, predictive critical value, sensitivity and specificity were 0.903, 0.660, 0.497, 0.795 and 0.865 respectively. Conclusions:This study is based on five independent risk factors of SLE patients' stress perception, namely SLE disease activity, resilience, anxiety, payment type, and family monthly income. The risk prediction model has good sensitivity and specificity, which can provide a reference for clinical assessment of health risk stress perception in SLE patients.
