This paper summarizes Professor LU Fang's clinical experience in treating systemic lupus erythematosus （SLE） based on the differentiation and treatment of heat-toxin and blood-stasis in the collaterals. SLE is generally characterized by deficiency in origin with excess in manifestation. The core pathogenesis is heat-toxin obstructing the collaterals. During the acute active stage， the predominant pattern is blazing heat-toxin causing blood stasis， while in the chronic remitting stage， the main pattern is toxic stasis blocking the collaterals with qi and yin deficiency. Clinical treatment follows the basic principle that treat with salty-cold herbs， when heat invades internally and that assist with acrid-dispersing herbs when stasis obstructs the collaterals. The self-formulated Yimian Decoction （抑免汤） serves as the base formula and is applied in stages. During the acute active stage， it is often combined with herbs for clearing heat and detoxifying， cooling blood and resolving stasis， and unblocking the collaterals. In the chronic remitting stage， it is often combined with herbs for activating blood circulation and unblocking the collaterals， as well as tonifying qi and nourishing yin.

This paper explores the therapeutic approach for glaucoma based on the concept of "jueyin （厥阴） as the closing phase" from the perspectives of time and space. In traditional Chinese medicine， jueyin governs inward， converging aspect of qi， representing the crucial turning point between the end of yin and the emergence of yang， as well as the transformation between yin and yang. When the closing and descending function of jueyin operates smoothly， it promotes the inward convergence and smooth descent of qi， enabling the internal retention of blood， spirit， and emotions， which nourishes the internal organs and moistens the meridian-sinews. Conversely， dysfunction of this "closing" mechanism results in a disturbance of yin and yang， a mixture of cold and heat， and disharmony of qi and blood. It is proposed that "failure of jueyin to properly close and descend" is a core pathomechanism of glaucoma. From the perspective of spatiotemporal theory， clinical treatment should focus on "regulating the closing function of jueyin and harmonizing yin and yang". The modified Wumei Pill （乌梅丸） is recommended to adjust the ascending-descending and entering-exiting dynamics of jueyin qi transformation， thereby restoring its free flow， achieving yin and yang balance， and ensuring nourishment to the ocular system.

Objective: To evaluate the impact of comprehensive nursing based on the behavioral goal attainment model on the clinical intervention effect among elderly female patients with stress urinary incontinence (SUI), so as to provide a basis for optimizing the nursing strategies for patients with SUI and improving their quality of life. Methods: A total of 190 elderly female patients with SUI who were treated in the Department of Gynecology of the First Hospital of Jilin University from January 2023 to August 2024 were selected and randomly divided into the intervention group and the control group. The control group received routine nursing care, while the intervention group received comprehensive nursing based on the behavioral goal attainment model. The 1-hour pad test was used to assess urinary incontinence symptoms. The bio-electrical stimulation feedback instrument was employed to detect the electromyogram (EMG) values in the pre-resting stage and slow-muscle stage for evaluating pelvic floor function. The bladder function scale was utilized to evaluate bladder function. The Chinese version of urinary incontinence ego-efficacy rating scales and incontinence quality of life assessment scale (IQOL) were used to assess self-efficacy and quality of life. The data on intervention compliance and nursing satisfaction were collected by a questionnaire survey. The differences between the two groups before and after the intervention were compared using the analysis of variance for repeated-measures data to evaluate the intervention effect. Results: There were 95 cases in the control group and 95 cases in the intervention group, with median ages were 64.00 (interquartile range, 23.50) and 64.50 (interquartile range, 19.50) years, respectively. The proportion of patients with cesarean section as the last delivery method was 21.05% in the control group and 12.63% in the intervention group. The proportion of patients with moderate disease severity was 67.36% in the control group and 58.95% in the intervention group. There were no statistically significant differences in age, body mass index, number of pregnancies, number of deliveries, marital status, educational level, mode of last delivery and severity of the disease between the two groups of patients (all P>0.05). The analysis of variance of repeated-measures data showed that there were significant interactions between time and group for the urine leakage volume in the 1-hour pad test, the EMG values in the pre-resting stage, the EMG values in the slow-muscle stage, the scores of the bladder function, the self-efficacy scores, and the IQOL scores (all P<0.05). After 12 weeks of intervention, the EMG values in the slow-muscle stage, the scores of the bladder function, the self-efficacy scores, the IQOL scores in the intervention group were higher than those in the control group, while the urine leakage volume in the 1-hour pad test and the EMG values in the pre-resting stage in the intervention group were lower than those in the control group (all P<0.05). The good compliance rate of intervention and the satisfaction rate of nursing in the intervention group were higher than those in the control group (83.16% vs. 60.00%, 90.53% vs. 75.79%, both P<0.05). Conclusion Comprehensive nursing based on the behavioral goal attainment model can improve urinary incontinence symptoms, pelvic floor function, bladder function, self-efficacy, quality of life, and intervention compliance of elderly female patients with SUI.

Objective To investigate the factors influencing poor prognosis in patients with persistent atrial fibrillation combined with heart failure undergoing catheter ablation.Methods The clinical data of 166 patients with persistent atrial fibrillation who underwent elective radiofrequency ablation in the Department of Cardiology of our hospital from January 2023 to June 2024 were retrospectively analyzed.Patients who under-went radiofrequency ablation and developed persistent atrial fibrillation were placed in the poor prognosis group(n=89),and those who did not develop heart failure were placed in the control group(n=77).Logistic regression analysis was used to identify factors influencing poor prognosis in patients with persistent atrial fi-brillation after catheter ablation;latent class analysis(LCA)was used to compare differences in the distribu-tion characteristics of influencing factors between the high-risk group for poor prognosis[B-type natriuretic peptide(BNP)>200 pg/mL]and the low-risk group(BNP≤200 pg/mL).Results There were statistically significant differences between the two groups of patients in terms of age,use of ACEI/ARB medications,dis-ease course,postoperative NYHA cardiac function classification,use of ivabradine,preoperative TG,preopera-tive TC,preoperative HDL-C,preoperative serum cholinesterase,preoperative galectin-3,preoperative LVEF,preoperative NT-proBNP,preoperative cTnI,and preoperative BNP(P<0.05).A disease course≥3.2 years,postoperative NYHA cardiac function classification score≥2 points,preoperative HDL-C<1.05 mmol/L,preoperative NT-proBNP≥12.5 μg/L,and preoperative BNP≥200.00 pg/mL were independent factors in-fluencing adverse outcomes in patients with persistent atrial fibrillation(P<0.05).LCA results showed that the"high-risk type distribution"accounted for a higher proportion in the high-risk group,while the"low-risk type distribution"accounted for a higher proportion in the low-risk group.The incidence of clinical endpoint e-vents in the poor prognosis group was 38.20%,higher than 9.09%in the control group(P<0.05).Conclu-sion Heart failure has an adverse effect on the prognosis of patients with persistent atrial fibrillation after catheter ablation,and there are differences in the incidence of adverse outcomes as well as the distribution characteristics of influencing factors between high-and low-risk groups.

Objective To analyze the endowment features of patients with primary angle-closure glaucoma(PACG)based on circuit-qi theory,thus to provide approaches for revealing the etiology,pathogenesis and prevalence of PACG.Methods From October 2023 to March 2024,a total of 204 patients with PACG admitted to the Eye Hospital,China Academy of Chinese Medical Sciences were enrolled into the analysis.The natal day of the patients was used for the calculation of conception day,and then the conception day was used for the analysis of the features of five circuits and six qi based on the stem-branch lunar year of conception day.A database of information of five circuits and six qi on conception day was constructed,and then the features of their endowments at conception were statistically analyzed.Results No statistically significant differences were shown in the distribution of the dominant qi,guest qi,sitian(celestial control)and zaiquan(terrestrial effect)at conception in PACG patients(P＞0.05),but there were statistically significant differences in the distribution of yearly circuit,comprehensive circuit-qi,and combined circuit-qi at conception in PACG patients(P＜0.05).Most of PACG patients had the circuit-qi features of shaomu(deficiency of wood)-yangming dryness gold-shaoyin monarch fire,and taitu(excess of earth)-shaoyin monarch fire-yangming dryness gold at conception.Conclusion Those who are conceived at the date with circuit-qi features of shaomu and taitu,comprehensive circuit-qi features of shaomu-yangming dryness gold-shaoyin monarch fire and taitu-shaoyin monarch fire-yangming dryness gold,and combined circuit-qi features of shunhua(qi generating circuit)and celestial restriction(qi restricting circuit)are vulnerability to PACG.The development of the constitution of PACG patients may be related to the congenital circuit-qi features of pathogenic dryness attacking the lung,and metal exuberance restricting wood.

Objective·To evaluate the changes in cognitive function in overweight and obese adolescents,and explore the association between cognitive function and fibroblast growth factor 21(FGF21).Methods·A total of 175 adolescents from a senior high school in Shanghai were divided into normal weight group(n=50),overweight group(n=50)and obese group(n=75)based on their body mass index(BMI).General information,anthropometric data and laboratory testing indicators of the adolescents were collected and compared.The cognitive function of the three groups of adolescents was assessed by using the accuracy(ACC)and reaction time of Flanker task and n-back task.Enzyme-linked immunosorbent assay(ELISA)was used to detect the serum FGF21 level of the three groups of adolescents.Partial correlation analysis and multiple linear regression model were used to evaluate the correlation between cognitive task performance and anthropometric data and laboratory testing indicators.Results·Compared with the normal weight group,systolic blood pressure,diastolic blood pressure,and the levels of fasting plasma glucose,glycosylated hemoglobin and triacylglycerol in the obese group were higher(all P<0.05).Under congruent or incongruent stimulus conditions in the Flanker task,there was no significant difference in ACC between any two groups;compared with the normal weight and overweight groups,the reaction time of the adolescents in the obese group was prolonged(all P<0.05).In the n-back task,there were no significant differences in ACC between any two groups,while the obese group had longer reaction time in the 1-back and 2-back tasks compared to the normal weight and overweight groups(all P<0.05).Compared with the normal weight group,serum FGF21 levels of the adolescents in the obese group were higher(P=0.000).Partial correlation analysis showed that the reaction time of the adolescents in Flanker and n-back tasks was correlated with their BMI,body fat mass,waist circumference,waist-to-hip ratio and FGF21 level(all P<0.05).Multiple linear regression analysis further confirmed that BMI was associated with prolonged reaction time in cognitive-related behavioral tasks in the adolescents(all P<0.05),and FGF21 level was associated with ACC in the 2-back task(P=0.000)and reaction time in the incongruent stimulus condition(P=0.048).Conclusion·Overweight and obese adolescents have cognitive impairments,and BMI and serum FGF21 levels are associated with changes in their cognitive function.

Tropane alkaloids (TAs) are a class of anticholinergic drugs widely used in clinical practice and mainly extracted from plant, among which Atopa belladonna is the main commercial drug source. It is of great industrial value to obtain TAs in large quantities by plant metabolic engineering. In TAs pathway, cytochrome oxidase CYP82M3 catalyze the synthesis of tropinone and then tropinone reductase I (TRI) compete with TRII for tropinone to form tropine leading to the TAs synthesis (drainage). In this study, based on the "increasing flow and drainage" metabolic engineering strategy, two genes, namely HnCYP82M3 and DsTRI from Hyoscyamus niger and Datura stramonium, respectively, were overexpressed in the hair roots of A. belladonna, with a view to promote the TAs accumulation. The HnCYP82M3 gene was cloned from the root of H. niger, and it encoded amino acid with 91.7% sequence identity with AbCYP82M3 from A. belladonna. Overexpression of HnCYP82M3 alone did not affect the content of TAs in hair roots of A. belladonna, indicating that CYP82M3 was not a key enzyme in TAs biosynthesis. Simultaneous overexpression of HnCYP82M3 and DsTRI greatly promoted the accumulation of the three TAs, and the contents of hyoscyamine, anisodamine and scopolamine were 4.97 times, 2.83 times and 2.19 times that of the control, respectively, and the increase amplitude was greater than that of single overexpression of DsTRI. This study showed that the "increasing flow and drainage" strategy of enzyme genes co-expression at branch points was a promising metabolic engineering method to effectively improve the biosynthesis of TAs in A. belladonna, and laid a theoretical and technical foundation for the large-scale industrial acquisition of TAs.

ObjectiveTo investigate the intervention effect of Jiedu Tongluo Tiaogan prescription （JTTP） in protecting pancreatic β cells by targeting the bile acid Takeda G protein-coupled receptor 5 （TGR5）/cyclic adenosine monophosphate （cAMP） signaling pathway against NOD-like receptor protein 3 （NLRP3） inflammasome. MethodThirty-two male SPF-grade db/db mice were randomly divided into the model group， low-dose JTTP group （3.6 g·kg^-1）， high-dose JTTP group （7.2 g·kg^-1）， and metformin group （0.2 g·kg^-1）. Eight db/m mice were assigned to the blank control group. The mice were treated with drugs for 8 weeks， and fasting blood glucose （FBG） was measured every 2 weeks. Oral glucose tolerance tests （OGTT） were conducted after the last administration. Enzyme-linked immunosorbent assay （ELISA） was performed to detect fasting insulin （FINS）， and the homeostasis model assessment of β-cell function （HOMA-β）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， and IL-1β levels were calculated. Hematoxylin-eosin （HE） staining was used to observe pathological changes in mouse pancreatic tissue. Immunofluorescence was performed to detect insulin expression in mouse pancreatic tissue. Western blot and real-time quantitative polymerase chain reaction （Real-time PCR） were used to detect the expression of proteins and mRNAs of key targets in the TGR5/cAMP signaling pathway and NLRP3 inflammasome. ResultCompared with blank group， FBG， OGTT， FINS， IL-6， TNF-α and IL-1β in model group were significantly increased （P<0.01）. Compared with model group， after 6 weeks of drug treatment， FBG level in JTTP group and metformin group decreased significantly （P<0.01）. The results of OGTT experiment showed that compared with model group， the blood glucose levels of mice in each administration group were decreased at all time points （P<0.05， P<0.01）， and the levels of FINS， TNF-α and IL-6 in JTTP dose groups and metformin group were significantly decreased. The level of IL-1β in JTTP high-dose group and metformin group was significantly decreased （P<0.01）. Pancreatic pathology showed that the islets in the model group were irregular in shape， uneven in distribution， and showed signs of atrophy. The prognosis of JTTP was that the cell count increased and the boundary was clearer. Immunofluorescence results showed that the islet cells in the blank group were arranged in an orderly and full shape with appropriate insulin secretion， while the islet cells in model group were distorted in shape， atrophy in structure and less insulin secretion. The insulin content of mice in JTTP and metformin group was significantly increased. Compared with blank group， mRNA expressions of NLRP3， apoptosis-related spot-like protein （ASC） and Caspase-1 in pancreatic tissues of model group were significantly increased （P<0.01）. Compared with model group， JTTP high-dose group and metformin group promoted the up-regulation of TGR5 and cAMP mRNA， and down-regulated the mRNA expressions of NLRP3， ASC and Caspase-1 （P<0.05， P<0.01）. Compared with blank group， the expression of TGR5 protein in model group was significantly decreased （P<0.01）. Compared with model group， TGR5 protein in JTTP high-dose group and metformin group was significantly increased （P<0.01）.

Objective:To explore the perinatal characteristics and early postnatal circulatory function of the larger fetus in monochorionic diamniotic twin pregnancy complicated with selective intrauterine growth restriction (sIUGR).Methods:From February 2018 to August 2022, a total of 91 larger fetuses of the sIUGR pregnancies who were hospitalized in the neonatal intensive care unit of Peking University Third Hospital were retrospectively included. The perinatal factors, clinical monitoring indicators, and echocardiographic data of the larger twins in pregnancies with three types of sIUGR were compared using one-way analysis of variance and LSD test, Kruskal-Wallis H test, Chi-square test, and Bonferroni correction. Results:The gestational age, birth weight, and placental weight were (30.6±1.5) weeks, (1 503.9±286.4) g, and (548±120) g in the type Ⅱ sIUGR larger twins and were (30.5±2.3) weeks, (1 523.5±424.4) g, and (560±109) g in type Ⅲ, which were all smaller, lower, and lighter than those in the type Ⅰ[(33.0±1.7) weeks, (2 022.1±372.3) g, and (630±131) g, respectively] (LSD test, all P<0.05). Compared with type Ⅰ sIUGR larger twins, type Ⅱ and Ⅲ sIUGR larger twins had longer hospital stay [36.0 d (27.0-43.0 d) and 32.0 d (15.0-47.0 d) vs. 17.0 d (9.5-22.0 d)], higher proportion of preterm births due to fetal distress [63.6% (21/33) and 75.0% (15/20) vs. 31.6% (12/38), χ2=7.30 and 9.93] (Bonferroni correction, all P<0.017); Compared with type Ⅰ sIUGR larger twins, type Ⅱ sIUGR larger twins had higher proportion of postnatal use of vasoactive drugs [45.5% (15/33) vs. 18.4% (7/38), χ2=6.04, P=0.014]. The interventricular septum thickness was larger in the type Ⅲ sIUGR larger twins than those in the type Ⅰ and Ⅱ twins [(4.4±1.4) vs. (3.8±0.9) and (3.3±0.9) mm]; the thickness of left ventricular free wall was the largest in the type Ⅲ larger twins, followed by those in the type Ⅰ and type Ⅱ [(4.6±1.3) vs. (3.1±0.7) vs. (2.7±0.6) mm]; the left ventricular end-diastolic diameter, right ventricular outflow tract diameter, right ventricular anteroposterior diameter, and pulmonary artery diameter in type Ⅰ larger twins were increased comparing with those in type Ⅱ and Ⅲ [left ventricular end-diastolic diameter: (15.0±2.1) vs. (13.4±2.3) and (12.3±3.2) mm; right ventricular outflow tract diameter: (8.7±1.4) vs. (7.3±1.4) and (7.1±0.8) mm; right ventricular anteroposterior diameter: (7.1±1.5) vs. (6.5±0.9) and (6.4±1.0) mm; pulmonary artery diameter: (6.8±1.1) vs. (6.3±0.9) and (6.3±0.8) mm] (LSD test, all P<0.05). Conclusion:The larger fetuses of type Ⅱ and Ⅲ sIUGR pregnancies had smaller gestational age and lighter birth weight who are more prone to have fetal distress, so it is necessary to strengthen dynamic monitoring and circulatory support for such neonates during the perinatal period and early postnatal period. The thickening of the left ventricular wall and interventricular septum in the early postnatal period of type Ⅲ larger fetuses may lead to the decrease of ventricular diastolic function reserve, thereby the evaluation and monitoring of the myocardial diastolic function of these neonates in the early postnatal period are critical.
