The ventral anterior (VA) nucleus of the thalamus is a major target of the basal ganglia and is closely associated with the pathogenesis of Parkinson's disease (PD). Notably, the VA receives direct innervation from the hypothalamic histaminergic system. However, its role in PD remains unknown. Here, we assessed the contribution of histamine to VA neuronal activity and PD motor deficits. Functional magnetic resonance imaging showed reduced VA activity in PD patients. Optogenetic activation of VA neurons or histaminergic afferents significantly alleviated motor deficits in 6-OHDA-induced PD rats. Furthermore, histamine excited VA neurons via H1 and H2 receptors and their coupled hyperpolarization-activated cyclic nucleotide-gated channels, inward-rectifier K⁺ channels, or Ca²⁺-activated K⁺ channels. These results demonstrate that histaminergic afferents actively compensate for Parkinsonian motor deficits by biasing VA activity. These findings suggest that targeting VA histamine receptors and downstream ion channels may be a potential therapeutic strategy for PD motor dysfunction.

OBJECTIVE: To establish and validate a novel diabetic retinopathy (DR) risk-prediction model using a whole-exome sequencing (WES)-based machine learning (ML) method. METHODS: WES was performed to identify potential single nucleotide polymorphism (SNP) or mutation sites in a DR pedigree comprising 10 members. A prediction model was established and validated in a cohort of 420 type 2 diabetic patients based on both genetic and demographic features. The contribution of each feature was assessed using Shapley Additive explanation analysis. The efficacies of the models with and without SNP were compared. RESULTS: WES revealed that seven SNPs/mutations ( rs116911833 in TRIM7, 1997T>C in LRBA, 1643T>C in PRMT10, rs117858678 in C9orf152, rs201922794 in CLDN25, rs146694895 in SH3GLB2, and rs201407189 in FANCC) were associated with DR. Notably, the model including rs146694895 and rs201407189 achieved better performance in predicting DR (accuracy: 80.2%; sensitivity: 83.3%; specificity: 76.7%; area under the receiver operating characteristic curve [AUC]: 80.0%) than the model without these SNPs (accuracy: 79.4%; sensitivity: 80.3%; specificity: 78.3%; AUC: 79.3%). CONCLUSION Novel SNP sites associated with DR were identified in the DR pedigree. Inclusion of rs146694895 and rs201407189 significantly enhanced the performance of the ML-based DR prediction model.

OBJECTIVE: To identify the key features of facial and tongue images associated with anemia in female populations, establish anemia risk-screening models, and evaluate their performance. METHODS: A total of 533 female participants (anemic and healthy) were recruited from Shuguang Hospital. Facial and tongue images were collected using the TFDA-1 tongue and face diagnosis instrument. Color and texture features from various parts of facial and tongue images were extracted using Face Diagnosis Analysis System (FDAS) and Tongue Diagnosis Analysis System version 2.0 (TDAS v2.0). Least Absolute Shrinkage and Selection Operator (LASSO) regression was used for feature selection. Ten machine learning models and one deep learning model (ResNet50V2 + Conv1D) were developed and evaluated. RESULTS: Anemic women showed lower a-values, higher L- and b-values across all age groups. Texture features analysis showed that women aged 30-39 with anemia had higher angular second moment (ASM)and lower entropy (ENT) values in facial images, while those aged 40-49 had lower contrast (CON), ENT, and MEAN values in tongue images but higher ASM. Anemic women exhibited age-related trends similar to healthy women, with decreasing L-values and increasing a-, b-, and ASM-values. LASSO identified 19 key features from 62. Among classifiers, the Artificial Neural Network (ANN) model achieved the best performance [area under the curve (AUC): 0.849, accuracy: 0.781]. The ResNet50V2 model achieved comparable results [AUC: 0.846, accuracy: 0.818]. CONCLUSION Differences in facial and tongue images suggest that color and texture features can serve as potential TCM phenotype and auxiliary diagnostic indicators for female anemia.

Objective To explore the correlation of bilateral knee joint strength asymmetry with balance,walking ability,and motor function in hemiplegic stroke patients,providing a reference for clinical assessment of stroke patients.Methods A total of 46 hemiplegic stroke patients admitted to the Rehabilitation Medicine Department of People's Hospital of Shijiazhuang from February to December 2023 were selected.According to the Berg Balance Scale(BBS)scores,patients were divided into Group A(BBS score≤20,n=23)and Group B(BBS score>20,n=23).The peak torque and differences of bilateral knee flexors and extensors were compared between two groups.Isokinetic technology was used to assess the differences in peak torque of bilateral knee joints at 60°/s and 120°/s.BBS,Functional Ambulation Classification(FAC),and Fugl-Meyer Assessment of Lower Extremity(FMA-LE)were used to evaluate patients'balance,walking ability,and lower limb motor function.The correlation between bilateral knee joint peak torque and its difference with the scores of three functional scales was analyzed.Results The peak torque of knee flexors and extensors at 60°/s in group A was significantly lower than that in group B(P<0.05).At both 60°/s and 120°/s the differences in peak torque between the healthy and affected sides of knee flexors and extensors were greater than those in group B(P<0.05).At 60°/s,the difference in peak torque of bilateral knee extensors in hemiplegic stroke patients was negatively correlated with the scores of BBS,FAC,and FMA-LE(r=-0.569,-0.582,-0.606,P<0.01),as did the knee flexors(r=-0.534,-0.386,-0.458,P<0.05).At 120°/s,similar negative correlations were observed for both knee extensors(r=-0.304,-0.304,-0.443,P<0.05)and flexors(r=-0.337,-0.349,-0.370,P<0.05).Conclusions Bilateral knee joint strength asymmetry in hemiplegic stroke patients is negatively correlated with balance and walking ability.The difference in strength between the two sides of knee joint may be one of the clinical indicators for evaluating the motor function of stroke patients.

Objective To report the diagnosis and treatment of a case of acute pulmonary embolism caused by thrombus detachment within a popliteal venous aneurysm and conduct a literature review,aiming to enhance the understanding of the disease.Methods The case data of a patient with pulmonary embolism caused by thrombus detachment within a popliteal venous aneurysm who was admitted to the Second Hospital of Lanzhou University were retrospectively analyzed.The relevant literature published from July 2014 to July 2023 in the CNKI and PubMed databases was retrieved,and the diagnosis and treatment methods of the disease were summarized.Results The patient in this case was a 61-year-old male,who was admitted was admitted to the hospital due to"intermittent chest tightness and shortness of breath for 5 days".Color Doppler ultrasound examination and pulmonary artery CT angiography(CTA)suggested popliteal venous aneurysm combined with intramural thrombus and pulmonary embolism.Therefore,the pulmonary embolism and popliteal venous aneurysm were treated surgically in stages.The patient recovered well after the operation and there were no symptoms of chest tightness or shortness of breath after discharge.A total of 11 literatures were retrieved,involving 11 patients,all of whom underwent surgical treatment;Among them,4 patients were treated with inferior vena cava filter placement,and 2 patients underwent popliteal venous aneurysm surgery after filter placement.Through literature review,it can be known that the etiology of popliteal venous aneurysm remains unclear,and there is no unified standard for diagnosis and treatment.Up to now,surgery is still the preferred option for treatment.Conclusions Patients with popliteal venous aneurysms may be asymptomatic but can lead to deep vein thrombosis of the lower limbs and subsequent pulmonary embolism.Surgical intervention is an effective treatment option.For patients with combined pulmonary embolism,especially those with recurrent pulmonary embolism,it is recommended to perform surgical treatment following placement of an inferior vena cava filter.

Objective To discuss the technical advantages of MRI image fusion technology in guiding percutaneous balloon compression(PBC)for trigeminal neuralgia(TN).Methods The clinical data of 13 patients with TN,who received MRI image fusion technology-guided PBC from November 2022 to July 2023,were retrospectively analyzed.The MRI images of the trigeminal nerve obtained one week before surgery were fused with the intraoperative DynaCT images of the skull base so as to simultaneously display the Meckel s cave and foramen ovale,and under the 3-D view the optimal puncture path was determined.The needle was positioned at the entry point of the skin,than the skin was cut open with a sharp surgical blade and the needle was inserted to the foramen ovale area to a predetermined depth.Lateral skull base fluoroscopy and DynaCT scan were used to check that the puncture needle tip was placed into the foramen ovale.Than the puncture needle was replaced by a fine guiding-needle and it was pushed into the Meckel's cave.Under the dual guidance of lateral fluoroscopy and fusion image,the balloon was push forward and was filled with iodine contrast media to compress the trigeminal ganglion within the Meckel's cave.After completion of the treatment,the balloon and puncture needle were removed and manual oppression was applied on the face to achieve hemostasis.Results Immediately after PBC,the pain was relieved in all patients.No permanent or serious complications occurred.One patient had a relapse 3 months after PBC and a second PBC procedure had to be carried out.No obvious pain recurrence was observed in the remaining patients during follow-up period.During the surgery,the mean number of foramen ovale puncturing was(1.31±0.46)times,the mean X-ray exposure time was(8.64±5.66)min,and the mean cumulative dose of X-ray was(570.29±257.15)mGy.After PBC,12 patients(92.31％)developed facial numbness and one patient(7.69％)developed facial pain,all of which were healed after treatment.Conclusion MRI image fusion technology can improve the visualization and accuracy of PBC procedure.It can also reduce the number of puncturing,decrease the radiation exposure dose,and improve the surgical ability of young doctors.Therefore,MRI image fusion technology should be further developed and applied in clinical practice.

Traditional Chinese medicine(TCM) resources are the essential material foundation for the development of TCM. The national survey of TCM resources serves as a periodic summary of these resources, ensuring the continuity, prosperity, and development of TCM in China. Since 1949, four national surveys of TCM resources have been conducted. The fourth survey incorporated an investigation into traditional knowledge related to TCM resources, including the traditional medicinal knowledge of Chinese ethnic minorities, with the goal of systematically exploring, preserving, and inheriting this knowledge. This manuscript provides an overview of the basic findings from the first three national surveys of TCM resources, while also clarifying the concepts, categories, forms, carriers, and acquisition pathways of traditional knowledge related to TCM resources. A preliminary summary of the findings from traditional knowledge investigations reported in current literature is also presented. Based on the fourth survey, this manuscript emphasizes the urgency of developing public medical knowledge through empirically-based investigations, the excavation, and compilation of traditional knowledge. It also outlines the potential for conducting "precise" investigations based on first-hand data obtained from the survey, as well as facilitating the discovery and evaluation of new medicines using traditional knowledge related to ethnic minority medicinal practices. This manuscript is expected to provide valuable insights for promoting the health and industrial development of ethnic minority populations in the post-"survey" phase.
