AIM: To evaluate the postoperative clinical efficacy of non-diffractive extended depth of focus intraocular lens(EDOF IOL)in patients with highly myopic cataract(HMC).METHODS:A retrospective analysis was conducted on the clinical data of patients diagnosed with HMC at the hospital from January 2022 to December 2024. Patients were divided into an observation group [undergoing femtosecond laser-assisted cataract surgery(FLACS)combined with non-diffractive EDOF IOL implantation] and a control group(undergoing FLACS combined with aspheric monofocal IOL implantation)according to the type of implanted IOL. Postoperative visual acuity(LogMAR), visual quality, and patient satisfaction were compared between the two groups.RESULTS: A total of 33 patients(47 eyes)were finally included in this study, including 10 patients(17 eyes)in the observation group and 23 patients(30 eyes)in the control group. The observation group had a median age of 59.0(52.8, 63.8)y, with 8 males(13 eyes)and 2 females(4 eyes). The control group had a median age of 56.0(53.5, 60.0)y, with 13 males(17 eyes)and 10 females(13 eyes). At 3 mo postoperatively, the best-corrected distance visual acuity(BCDVA)was 0.10(0.08, 0.12)in the observation group and 0.20(0.10, 0.40)in the control group(P=0.586). However, the best-corrected intermediate visual acuity(BCIVA)[0.10(0.10, 0.10)vs 0.50(0.40, 0.90), P=0.032] and best-corrected near visual acuity(BCNVA)[0.20(0.18, 0.20)vs 0.60(0.45, 1.45), P=0.044] in the observation group were significantly better than those in the control group. The defocus curve showed that the uncorrected visual acuity(UCVA)in the observation group was relatively stable within the range of -2.00 to +1.00 D, which was superior to that in the control group. Postoperative questionnaires showed that the spectacle independence rate(76%)and overall satisfaction(88%)in the observation group were significantly higher than those in the control group(10% and 60%, respectively).CONCLUSION: Non-diffractive EDOF IOL significantly improves intermediate and near visual acuity, reduces spectacle dependence, and maintains distance visual acuity by extending the depth of focus, providing better postoperative visual quality and life satisfaction for HMC patients.

Bronchiolar adenoma (BA) is a rare type of lung tumor characterized by bilayered epithelial cells having a continuous basal layer and a luminal layer. It resembles mucinous adenocarcinoma (MA) on frozen section, with difficulty in distinguishing the basal layer. Immunohistochemistry is the best choice for verifying the diagnosis. This study aimed to comprehensively characterize three cases of BA-combined carcinoma using clinical, histopathological, and genetic features. BA and carcinoma sections were subjected to next-generation sequencing, respectively. It was hypothesized that while different mutation forms matched different regions, BA and lung adenocarcinoma shared the same gene mutation when they co-occurred in the same location. BA with extensive carcinoma is extremely rare and presents diagnostic challenges due to its overlap with conditions such as MA. Because of its distinctive morphological characteristics, BA may be regarded as a low-grade malignancy, particularly during a confusing evaluation. A multifaceted examination of clinical, radiological, immunohistochemical, and genetic data is necessary for an accurate diagnosis.

ObjectiveTo observe the clinical efficacy and safety of Yanghe Xiaonang Decoction (阳和消囊汤, YXD) in the treatment of polycystic ovarian syndrome (PCOS)-related infertility with healthy qi deficiency and phlegm stasis syndrome. MethodsA total of 120 PCOS-related infertility participants with healthy qi deficiency and phlegm stasis syndrome were randomly divided into a treatment group and a control group in a 1∶1 ratio, with 60 cases in each group. The treatment group started taking YXD on the first day of the menstrual cycle, one dose daily, until the day of sexual intercourse when follicles matured and were released. Those without mature follicles or ovulation could take it until the 14th to 28th day. The control group was given oral letrozole at 2.5 mg daily starting on the 5th day of the menstrual cycle for 5 consecutive days. If the basal body temperature curve remained monophasic on the 28th day of the menstrual cycle, and no dominant follicle was detected by color Doppler ultrasound, estrogen plus progesterone or progesterone alone was administered for withdrawal bleeding, followed by a new treatment cycle. The treatment lasted for three consecutive menstrual cycles. Patients were followed up for 3 months upon confirmed pregnancy or after the completion of the 3rd treatment cycle. The clinical pregnancy rate, total effective rate, pregnancy rate, biochemical pregnancy rate, embryonic arrest rate, and ectopic pregnancy rate between the two groups were compared. Transvaginal color Doppler ultrasound was used for monitoring endometrial thickness, cyclic ovulation status, number of follicles between 2-9 mm, and the difference in transverse and longitudinal diameters of dominant follicles. The levels of endocrine hormone indicators including serum testosterone (T), prolactin (PRL), luteinizing hormone (LH), follicle-stimulating hormone (FSH), progesterone (P), estradiol (E2), free testosterone (F-T), androstenedione (ASD), inhibin B (INH-B), and anti-Müllerian hormone (AMH), as well as the total traditional Chinese medicine (TCM) symptom scores before and after treatment were compared between the two groups. ResultsA total of 58 patients in each group were included in the statistical analysis. The clinical pregnancy rate in the treatment group was 39.66% (23/58), higher than 22.41% (13/58) in the control group (P<0.05). The total effective rate in the treatment group was 96.55% (56/58), higher than 79.31% (46/58) in the control group (P<0.05). The biochemical pregnancy rate and embryonic arrest rate in the treatment group were lower than those in the control group (P<0.05). The treatment group was superior to the control group in increasing endometrial thickness and reducing the number of 2-9 mm follicles at the 2nd and 3rd cycles, as well as in improving the cyclic ovulation status and the difference in transverse and longitudinal diameters of dominant follicles at the 3rd cycle (P<0.05). After treatment, the treatment group exhibited significant reductions in serum T, LH, F-T, ASD, INH-B, and AMH levels (P<0.05). The control group also showed significant decreases in LH, F-T, INH-B, and AMH levels (P<0.05). The levels of F-T, INH-B, and AMH in the treatment group after treatment were lower than those in the control group (P<0.05). The improvement of the total TCM symptom score in the treatment group was superior to that in the control group (P<0.05). ConclusionYXD can significantly improve the clinical pregnancy rate, reduce the rates of biochemical pregnancy and embryonic arrest, alleviate clinical symptoms, increase endometrial thickness, enhance dominant follicles, and improve endocrine hormone levels in PCOS-related infertility with healthy qi deficiency and phlegm stasis syndrome, showing good safety.

ObjectiveINF2 is a member of the formins family. Abnormal expression and regulation of INF2 have been associated with the progression of various tumors, but the expression and role of INF2 in hepatocellular carcinoma (HCC) remain unclear. HCC is a highly lethal malignant tumor. Given the limitations of traditional treatments, this study explored the expression level, clinical value and potential mechanism of INF2 in HCC in order to seek new therapeutic targets. MethodsIn this study, we used public databases to analyze the expression of INF2 in pan-cancer and HCC, as well as the impact of INF2 expression levels on HCC prognosis. Quantitative real time polymerase chain reaction (RT-qPCR), Western blot, and immunohistochemistry were used to detect the expression level of INF2 in liver cancer cells and human HCC tissues. The correlation between INF2 expression and clinical pathological features was analyzed using public databases and clinical data of human HCC samples. Subsequently, the effects of INF2 expression on the biological function and Drp1 phosphorylation of liver cancer cells were elucidated through in vitro and in vivo experiments. Finally, the predictive value and potential mechanism of INF2 in HCC were further analyzed through database and immunohistochemical experiments. ResultsINF2 is aberrantly high expression in HCC samples and the high expression of INF2 is correlated with overall survival, liver cirrhosis and pathological differentiation of HCC patients. The expression level of INF2 has certain diagnostic value in predicting the prognosis and pathological differentiation of HCC. In vivo and in vitro HCC models, upregulated expression of INF2 triggers the proliferation and migration of the HCC cell, while knockdown of INF2 could counteract this effect. INF2 in liver cancer cells may affect mitochondrial division by inducing Drp1 phosphorylation and mediate immune escape by up-regulating PD-L1 expression, thus promoting tumor progression. ConclusionINF2 is highly expressed in HCC and is associated with poor prognosis. High expression of INF2 may promote HCC progression by inducing Drp1 phosphorylation and up-regulation of PD-L1 expression, and targeting INF2 may be beneficial for HCC patients with high expression of INF2.

The phase changes and quantity-quality transfer of 17 batches of Ostreae Concha(Ostrea rivularis) during the raw material-calcined decoction pieces-standard decoction process were analyzed. The content of calcium carbonate(CaCO_3), the main component, was determined by chemical titration, and the extract yield and transfer rate were calculated. The CaCO_3 content in the raw material, calcined decoction pieces, and standard decoction was 94.39%-98.80%, 95.03%-99.22%, and 84.58%-90.47%, respectively. The process of raw material to calcined decoction pieces showed the yield range of 96.85% to 98.55% and the CaCO_3 transfer rate range of 96.92% to 99.27%. The process of calcined decoction pieces to standard decoction showed the extract yield range of 2.86% to 5.48% and the CaCO_3 transfer rate range of 2.59% to 5.13%. The results of X-ray fluorescence(XRF) assay showed that the raw material, calcined decoction pieces, and standard decoction mainly contained Ca, Na, Mg, Si, Br, Cl, Al, Fe, Cr, Mn, and K. The chemometric results showed an increase in the relative content of Cr, Fe, and Si from raw material to calcined decoction pieces and an increase in the relative content of Mg, Al, Br, K, Cl, and Na from calcined decoction pieces to standard decoction. X-ray diffraction(XRD) was employed to establish XRD characteristic patterns of the raw material, calcined decoction pieces, and standard decoction. The XRD results showed that the main phase of all three was calcite, and no transformation of crystalline form or generation of new phase was observed. Fourier transform infrared spectroscopy(FTIR) was employed to establish the FTIR characteristic spectra of the raw material, calcined decoction pieces, and standard decoction. The FTIR results showed that the raw material had internal vibrations of O-H, C-H, C=O, C-O, and CO■ groups. Due to the loss of organic matter components after calcination, no information about the vibrations of C-H, C=O, and C-O groups was observed in the spectra of calcined decoction pieces and standard decoction. In summary, this study elucidated the quantity-quality transfer and phase changes in the raw material-calcined decoction pieces-standard decoction process by determining the CaCO_3 content, calculating the extract yield and transfer rate, and comparing the element changes, FTIR characteristic spectra, and XRD characteristic pattern. The results were reasonable and reliable, laying a foundation for the subsequent process research and quality control of the formula granules of calcined Ostreae Concha(O. rivularis Gould), and providing ideas and methods for the quality control of the whole process of raw material-decoction pieces-standard decoction-formula granules of Ostreae Concha and other testacean traditional Chinese medicine.

ObjectiveTo investigate the antidepressant effects and mechanisms of total flavonoids from Cuscutae Semen (TFCC) in the mouse model of chronic unpredictable mild stress (CUMS). MethodsFifty male 4-week-old ICR mice were randomized into five groups (n=10 per group): blank control, model, Cuscutae Semen decoction (10.2 g·kg-1·d-1), paroxetine (2.6 mg·kg-1·d-1), and TFCC (173.2 mg·kg-1·d-1). The other groups except the blank control group underwent chronic unpredictable mild stress (CUMS) for 4 weeks. Behavioral assessments were conducted post-modeling. Then, the model group received distilled water (10 mL·kg-1·d-1), while treatment groups were administrated with respective agents via oral gavage (10 mL·kg-1) for 4 weeks. Depression-like behaviors were evaluated by the sucrose preference test (SPT), forced swimming test (FST), and tail suspension test (TST). Hippocampal neuronal morphology was observed via hematoxylin-eosin staining, and apoptosis in the brain tissue was assessed via terminal- deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL). Enzyme-linked immunosorbent assay (ELISA) was employed to measure the hippocampal levels of inflammatory cytokines [interleukin (IL)-1β, IL-6, and TNF-α)] and neurotransmitters [5-hydroxytryptamine (5-HT), dopamine (DA), and brain-derived neurotrophic factor (BDNF)], while the reactive oxygen species (ROS) levels were quantified via the DCFH-DA probe. Real-time PCR was performed to measure the mRNA levels of NOD-like receptor protein 3 (NLRP3), apoptosis-associated Speck-like protein containing a CARD (ASC), cysteinyl aspartate-specific proteinase-1 (Caspase-1), IL-1β, and inducible nitric oxide synthase (iNOS). Western blot was employed to evaluate the protein levels of NLRP3, ASC, Caspase-1, uncoupling protein 2 (UCP2), and thioredoxin-interacting protein (TXNIP). ResultsCompared with the blank control group, the model group exhibited weight loss (P<0.01), reduced sucrose preference (P<0.01), prolonged immobility time in FST and TST (P<0.01), neuron disarrangement with nuclear pyknosis in hippocampal CA3 region, increased apoptosis in the brain tissue, elevated levels of IL-1β, IL-6, and TNF-α (P<0.01), declined levels of 5-HT, DA, and BDNF (P<0.01), increased ROS accumulation (P<0.01), upregulated mRNA levels of NLRP3, ASC, Caspase-1, IL-1β, and iNOS (P<0.01), down-regulated protein level of UCP2 (P<0.01), and up-regulated protein levels of NLRP3, ASC, Caspase-1, and TXNIP (P<0.01). Compared with the model group, the interventions restored sucrose preference (P<0.01), shortened immobility time (P<0.01), repaired hippocampal neuronal structure, reduced apoptosis, lowered the levels of inflammatory cytokines (P<0.01), restored the levels of neurotransmitters (P<0.01), alleviated ROS accumulation (P<0.01), downregulated the mRNA levels of NLRP3, ASC, Caspase-1, IL-1β, and iNOS (P<0.01), upregulated the protein level of UCP2 (P<0.01), and reduced the protein levels of NLRP3, ASC, Caspase-1, and TXNIP (P<0.01). Moreover, TFCC outperformed Cuscutae Semen decoction in ameliorating depressive behaviors. TFCC excelled in neuronal repair, neurotransmitter regulation, anti-inflammatory effects, and modulation of the UCP2/TXNIP/NLRP3 pathway (P<0.05). ConclusionTFCC modulates the hippocampal UCP2/TXNIP/NLRP3 pathway to inhibit inflammasome activation, reduce oxidative stress, restore neurotransmitters, thus suppressing neuronal apoptosis and promoting the rearrangement and morphology recovery of hippocampal cells. It outperforms Cuscutae Semen decoction in the antidepressant efficacy.

ObjectiveTo evaluate the efficacy and safety of Xiaoji Hufei Formula in protecting children with close contact exposure to influenza, and to provide reference and evidence-based support for better clinical prevention and treatment of influenza in children. MethodsA multicenter, prospective, non-randomized, parallel, controlled trial was conducted from October 2021 to May 2022 in five hospitals, including Dongfang Hospital of Beijing University of Chinese Medicine. Confirmed influenza cases and influenza-like illness (ILI) cases were collected, and eligible children with close contact exposure to these cases were recruited in the outpatient clinics. According to whether the enrolled close contacts were willing to take Xiaoji Hufei formula for influenza prevention, they were assigned to the observation group (108 cases) or the control group (108 cases). Follow-up visits were conducted on days 7 and 14 after enrollment. The primary outcomes were the incidence of ILI and the rate of laboratory-confirmed influenza. Secondary outcomes included traditional Chinese medicine (TCM) symptom score scale for influenza, influenza-related emergency (outpatient) visit rate, influenza hospitalization rate, and time to onset after exposure to influenza cases. ResultsA total of 216 participants were enrolled, with 108 in the observation group and 108 in the control group. Primary outcomes: (1) Incidence of ILI: The incidence was 12.0% (13/108) in the observation group and 23.1% (25/108) in the control group, with the observation group showing a significantly lower incidence (χ2=4.6, P<0.05). (2) Influenza confirmation rate: 3.7% (4/108) in the observation group and 4.6% (5/108) in the control group, with no statistically significant difference. Secondary outcomes: (1) TCM symptom score scale: after onset, nasal congestion and runny nose scores differed significantly between the two groups (P<0.05), while other symptoms such as fever, sore throat, and cough showed no significant differences. (2) Influenza-related emergency (outpatient) visit rate: 84.6% (11 cases) in the observation group and 96.0% (24 cases) in the control group, with no significant difference. (3) Time to onset after exposure: The median onset time after exposure to index patients was 7 days in the observation group and 4 days in the control group, with a statistically significant difference (P<0.05). ConclusionIn previously healthy children exposed to infectious influenza cases under unprotected conditions, Xiaoji Hufei formula prophylaxis significantly reduced the incidence of ILI. Xiaoji Hufei Formula can be recommended as a specific preventive prescription for influenza in children.

This paper summarizes Professor WANG Xiuxia's clinical experience in treating hyperprolactinemia using the liver soothing therapy. Professor WANG identifies liver qi stagnation and rebellious chong qi (冲气) as the core pathomechanisms of hyperprolactinemia. Furthermore, liver qi stagnation may transform into fire or lead to pathological changes such as spleen deficiency with phlegm obstruction or kidney deficiency with essence depletion. The treatment strategy centers on soothing the liver, with a modified version of Qinggan Jieyu Decoction (清肝解郁汤) as the base formula. Depending on different syndrome patterns such as liver stagnation transforming into fire, liver stagnation with spleen deficiency, or liver stagnation with kidney deficiency, heat clearing, spleen strengthening, or kidney tonifying herbs are added accordingly. In addition, three paired herb combinations are commonly used for symptom specific treatment, Danggui (Angelica sinensis) with Chuanxiong (Ligusticum chuanxiong), Zelan (Lycopus lucidus) with Yimucao (Leonurus japonicus) , and Jiegeng (Platycodon grandiflorus) with Zisu (Perilla frutescens).

ObjectiveFunctional near-infrared spectroscopy (fNIRS), a novel non-invasive technique for monitoring cerebral activity, can be integrated with upper limb rehabilitation robots to facilitate the real-time assessment of neurological rehabilitation outcomes. The rehabilitation robot is designed with 3 training modes: passive, active, and resistance. Among these, the resistance mode has been demonstrated to yield superior rehabilitative outcomes for patients with a certain level of muscle strength. The control modes in the resistance mode can be categorized into dynamic and static control. However, the effects of different control modes in the resistance mode on the motor function of patients with upper limb hemiplegia in stroke remain unclear. Furthermore, the effects of force, an important parameter of different control modes, on the activation of brain regions have rarely been reported. This study investigates the effects of dynamic and static resistance modes under varying resistance levels on cerebral functional alterations during motor rehabilitation in post-stroke patients. MethodsA cohort of 20 stroke patients with upper limb dysfunction was enrolled in the study, completing preparatory adaptive training followed by 3 intensity-level tasks across 2 motor paradigms. The bilateral prefrontal cortices (PFC), bilateral primary motor cortices (M1), bilateral primary somatosensory cortices (S1), and bilateral premotor and supplementary motor cortices (PM) were examined in both the resting and motor training states. The lateralization index (LI), phase locking value (PLV), network metrics were employed to examine cortical activation patterns and topological properties of brain connectivity. ResultsThe data indicated that both dynamic and static modes resulted in significantly greater activation of the contralateral M1 area and the ipsilateral PM area when compared to the resting state. The static patterns demonstrated a more pronounced activation in the contralateral M1 in comparison to the dynamic patterns. The results of brain network analysis revealed significant differences between the dynamic and resting states in the contralateral PFC area and contralateral M1 area (F=4.709, P=0.038), as well as in the contralateral PM area and ipsilateral M1 area (F=4.218, P=0.049). Moreover, the findings indicated a positive correlation between the activation of the M1 region and the increase in force in the dynamic mode, which was reversed in the static mode. ConclusionBoth dynamic and static resistance training modes have been demonstrated to activate the corresponding brain functional regions. Dynamic resistance modes elicit greater oxygen changes and connectivity to the region of interest (ROI) than static resistance modes. Furthermore, the effects of increasing force differ between the two modes. In patients who have suffered a stroke, dynamic modes may have a more pronounced effect on the activation of exercise-related functional brain regions.
