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.

AIM: To investigate the diagnostic value of the axial length/corneal radius of curvature(AL/CR)for myopia in children and adolescents.METHODS: PubMed, Embase, The Cochrane Library, CNKI, CBM, WanFang Data and VIP databases were searched to collect clinical research on the value of AL/CR in diagnosing myopia in children and adolescents, and the retrieval time was from establishment to September 30, 2023. The QUADAS-2 tool was used to evaluate the quality of the extracted literature. A random-effects model was used to pool diagnostic test data, Meta-regression and subgroup analysis were performed to explore sources of heterogeneity.RESULTS: A total of 10 articles involving 19 872 study participants were included, and Meta-analysis showed that the pooled sensitivity of the AL/CR for the diagnosis of myopia in children and adolescents was 0.91[95%CI(0.90-0.91)], the pooled specificity was 0.84 [95%CI(0.84-0.85)], and area under the SROC curve of 0.95 [95%CI(0.93-0.96)].CONCLUSION: The AL/CR is a good indicator of myopia in children and adolescents.

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.

The theory of “rhythmic equilibrium” is developed based on the idea of sharing the same laws between nature and human， and by integrating with the medical concept of homeostasis of calm yin and sound yang. "Rhythmic instability" runs through the entire process of the occurrence and development of myopia， covering four aspects including imbalance of rhythm （high-risk period of myopia）， imbalance of qi and blood （premyopia）， imbalance of sinew-membranes （low myopia）， and imbalance of essence and blood （high myopia）. The treatment should focus on adjusting the rhythm and harmonizing situation， which can help balance yin and yang， and nourish the eye system. For high-risk period of myopia， adjusting sleeping time and increasing outdoor activities are stressed to adjust the rhythm in a timely manner. In the stage of premyopia， appropriate techniques of traditional Chinese medicine （TCM） such as pressing needles can be added to harmonize qi and blood. In the period of low myopia， appropriate TCM techniques such as pressing needles and ear acupuncture are mainly used， supplemented by modified Danggui Buxue Decoction （当归补血汤） to soften tendons and unblock collaterals. During the period of high myopia， it is recommended to control the development of existing disease and put focus on nourishing essence and blood， usually with Zhujing Pill （驻景丸） or modified Siwu Wuzi Decoction （四物五子汤） to restore the stability of the eyes and the whole body.

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.

Purpose To investigate the expression status of GNL3 in gastric cancer,and to explore the role of GNL3 in tumor proliferation,invasion and migration.Methods The ex-pression of GNL3 mRNA in gastric cancer tissues was analyzed by searching database.The expression of GNL3 protein in 51 gastric cancer tissues and 51 adjacent non-tumor tissues was de-tected by immunohistochemistry(IHC)SP method.The correla-tion between GNL3 protein expression and gastric cancer clinical pathological features was analyzed by x2 test.The expression of GNL3 in gastric cancer cells was silenced by transfection of sh-RNA,and the silencing efficiency was verified by Western blot.The effect of silencing GNL3 on the proliferation of gastric cancer cells was examined by CCK-8,colony formation and EdU stai-ning.In addition,wound-healing assay and Transwell assay were performed to detect the effect of GNL3 silencing on cell invasion and migration.Results SangerBox and UALCAN database re-trieval showed that the expression of GNL3 mRNA was signifi-cantly increased in gastric cancer tissues(P＜0.01).IHC stai-ning showed that the positive expression rate of GNL3 protein in gastric cancer tissues was 96.1％,and the high expression rate was 78.4％,which was significantly higher than that in adjacent non-tumor tissues(74.5％,51.0％,P＜0.01).Moreover,the high expression of GNL3 was significantly correlated with lymph node metastasis in gastric cancer patients(x2=4.933,P=0.026).CCK-8,colony formation and EdU staining showed that GNL3 silencing inhibited the proliferation of gastric cancer cell SGC-7901.The wound-healing and Transwell assay showed that GNL3 silencing inhibited the migration and invasion of gastric cancer cell.Conclusion The GNL3 protein is highly expressed in gastric cancer tissues,and closely related to the proliferation,migration and invasion of gastric cancer cells.

In recent years,the global prevalence of obesity has continued to rise,with a preference for high-sugar and high-fat foods being one of the primary contributors to this condition.Food preference refers to the degree of individual liking for specific foods,and its formation is closely related to the physiological effects such as satiety,satisfaction and reward that occur after food digestion in the gastrointestinal tract.With the continuous advancement of technologies such as neuroimaging and chemogenetics,the underlying neural and physiological mechanisms of food preference behavior are gradually being elucidated.Studies have shown that the digestion and absorption of food in the gastrointestinal tract can release chemical or electrical signals,which are transmitted to the central nervous system via neural pathways,humoral pathways and the gut-brain axis mediated by gut microbiota.Subsequently,these signals regulate feeding behavior by activating or inhibiting neurons in the nucleus of the solitary tract,the dopaminergic reward pathways and relevant neural circuits in the hypothalamus.Based on this,the article introduces the definition,evaluation methods and mechanisms of food preference,and reviews the pathways of food information transmission within the gut-brain axis,the reward circuits that modulate food preference and the application of food preference behavior to the treatment of obesity,in order to provide reference for research in the field of food preference and obesity treatment.

OBJECTIVE To investigate the effect and mechanism of action of KRT8 small interfering RNA(si-KRT8)in exosomes derived from patient serum with hypopharyngeal carcinoma on chemosensitivity to 5-fluorouracil(5-FU)in human pharyngeal squamous cell carcinoma FaDu cell line.METHODS The cancerous tissues of hypopharyngeal cancer patients and The serum,cancerous tissues and paracancerous tissues of drug-resistant patients after treatment were collected.A 5-FU-resistant cell line of FaDu(FaDu/R)was constructed for subsequent experiments.Exosomes were isolated from patient serum by ultrafast gradient centrifugation,identified using transmission electron microscopy and Western blot(WB)techniques.si-KRT8 was encapsulated into exosomes(Exosome@si-KRT8)using electroporation technology and subsequently used to treat cells.Real-time fluorescence quantitative PCR(RT-qPCR)and WB were used to detect the expression levels of KRT8 in different tissues,exosomes after electroporation of si-KRT8,and FaDu cells,respectively.Cell counting kit-8(CCK-8),terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling assay,migration invasion technique and WB were used to detect the effects of Exosome@si-KRT8 on viability,apoptosis,and epithelial-mesenchymal transition of FaDu/R cells.RESULTS The expression level of KRT8 in drug-resistant tissues of hypopharyngeal carcinoma and FaDu/R cells was elevated compared with that in paraneoplastic tissues,cancer tissues and normal FaDu cells(t=15.79,P＜0.01).Isolated patient serum exosomes showed a double membrane structure and expressed both CD63 and TSG101 proteins,and KRT8 expression in exosomes was decreased after electro-transfection with si-KRT8(t=6.70,P＜0.01).Exosome@si-KRT8 inhibited KRT8 protein expression levels in FaDu/R cells(t=123.50,P＜0.01).Compared with the 5-FU group and the 5-FU+Exosome group,Exosome@si-KRT8 was able to inhibit the viability of FaDu/R cells(t=17.07,P＜0.01),promote the level of apoptosis in FaDu/R cells,and inhibit the expression of drug-resistance-associated proteins in FaDu/R cells(P-gp:t=103.20,MDR1:t=238.60,P＜0.01),and Exosome@si-KRT8 was able to suppress the expression of metastasis of FaDu/R cells(t=42.30,t=122.00,P＜0.01)and promoted the expression of E-cadherin while inhibiting the expression level of N-cadherin(t=130.80,t=83.90,P＜0.01).CONCLUSION Serum-derived exosome encapsulation of si-KRT8 enhances chemosensitivity of hypopharyngeal carcinoma cells and its mechanism of action may be related to inhibition of epithelial-mesenchymal transition.
