In recent years， hyperuricemia （HUA） has shown a rapidly increasing incidence and tends to occur in increasingly young people， with a wide range of cardiac， renal， joint， and cancerous hazards and all-cause mortality associations. Western medicine treatment has limitations such as large liver and kidney damage， medication restriction， and easy recurrence. The intestine is the major extra-renal excretion pathway for uric acid （UA）， and the intestinal microecology can be regulated to promote UA degradation. It offers great potential to develop UA-lowering strategies that target the intestinal microecology， which are promising to provide safer and more effective therapeutic approaches. Traditional Chinese medicine （TCM） can treat HUA via multiple targets and multiple pathways from a holistic view， with low toxicity and side effects. Studies have shown that intestinal microecology is a crucial target for TCM in the treatment of HUA. However， its specific mechanism of action has not been fully elucidated. Focusing on the key role of intestinal microecology in HUA， this review explores the relationship between intestinal microecology and HUA in terms of intestinal flora， intestinal metabolites， intestinal UA transporters， and intestinal barriers. Furthermore， we summarize the research progress in TCM treatment of HUA by targeting the intestinal microecology， with the aim of providing references for the development of TCM intervention strategies for HUA and the direction of future research.

Background: and Purpose Guillain–Barré syndrome (GBS) is an autoimmune-mediated disorder characterized by demyelinating or axonal injury of the peripheral nerve. Our aim is to determine whether serum amyloid A (SAA) is a biomarker of demyelinating injury and disease severity in patients with GBS. Methods: This study retrospectively enrolled 40 patients with either the demyelinating or axonal GBS and sex- and age-matched controls with other neurological diseases as well as healthy subjects. The demographic and clinical features at entry were collected. The serum levels of the SAA isoforms SAA1, SAA2, and SAA4 were determined in the patients with GBS and the controls using the enzyme-linked immunosorbent assay and analyzed for the associations between levels of different SAA isoforms and the clinical features of the patients. Results: The levels of SAA2 and SAA4 were significantly higher in patients with GBS than in both the other neurological disease controls and the healthy subjects (p<0.05 for all). The level of SAA1 did not differ between patients with GBS and the controls. The level of SAA2 was considerably higher in GBS patients with antecedent infection than in those without infection (p=0.020). The levels of different SAA isoforms were not associated with the disease severity or other clinical features of patients with GBS (p>0.05 for all). Conclusions Increased levels of SAA2 and SAA4 may only represent the acute inflammatory status and so cannot be utilized as biomarkers of the disease severity or demyelinating injury in patients with GBS.

The importance of gait assessment in the rehabilitation of cancer patients is gradually being recognized. However, quantitative analysis of balance ability in cancer patients is still limited. A total of 102 cancer patients meeting the inclusion criteria were recruited from Hefei Cancer Hospital, Chinese Academy of Sciences. Their balance ability was evaluated using the Berg Balance Scale (BBS). Gait data were collected by an electronic walkway and an IMU sensor system, including spatial-temporal and kinematic gait features such as step length, cadence, support time, and range of motion. Recursive feature elimination was used for feature selection. Ridge, Elastic Net, SVR, RF, and AdaBoost models were used to predict balance ability scores. Five-fold cross-validation was used to evaluate the performance of these models. Results show that the SVR model achieves the best performance with fifteen features (RMSE=3.22, R ²=0.91), followed by Ridge (RMSE=3.63, R ²=0.89). A method for evaluating balance ability based on gait features is proposed, providing a quantitative tool for personalized rehabilitation interventions in cancer patients.

Based on the clinical thinking of combining diseases and patterns， we combined disease identification， pattern differentiation， and constitution identification， and put forward the theory of identifying and treating critical hypertension， which is "examining the symptoms first， identifying the constitutions as reference， and combining the diseases and patterns". Firstly， the starting point of identifying the disease is to examine the symptoms， and those with precise diagnosis and strong specificity will be diagnosed with the disease， while those with relatively broad diagnosis and fuzzy characteristics will be emphasised on identifying constitutions and differentiating patterns. Focusing on the impact of constitution identification on disease identification and pattern differentiation， constitution identification could be the basis when no symptoms to identify， and based on the theory of "constitution-disease correlation" and "constitution-pattern correlation" to improve the understanding of borderline hypertension from the group and individual level， which helps to identify and predict the development of the diseases and patterns； if the symptoms are complicated and difficult to identify， it is necessary to take syndrome as the outline， use the syndrome to unify the disease， and then refer to the constitution to legislate and prescribe medications. This paper summarizes the traditional Chinese medicine clinical differentiation and treatment strategy of borderline hypertension clear and easy to grasp， with a view to provide a feasible and efficient reference for prevention and treatment of borderline hypertension with traditional Chinese medicine.

Based on the theory of "disease involving both dryness and dampness"， it is believed that the complex of dryness and dampness and the mutual stalemate between them produce the disease， forming a pathological state of dampness within dryness and dryness within dampness. The two can occur accompanied by each other， transform into each other， and coexist as a disease. According to the clinical characteristics of sjögren's syndrome-related dry eye disease （SS-DED）， it is believed that its symptoms can reflect the pathological state of coexistence of dryness and dampness， and that "disease involving both dryness and dampness" is the key pathogenesis. The main treatment principles are performing both purgation and tonification， and treating the dryness and dampness simultaneously. The treatment should focus on rectifying qi， fortifying spleen and dispelling dampness， as well as opening orifices， nou-rishing yin and moistening dryness， usually with Shashen Maidong Decoction （沙参麦冬汤） and Xiangsha Liujunzi Decoction （香砂六君子汤） in modifications. The theory of "disease involving both dryness and dampness" is expected to provide ideas for the diagnosis and treatment of SS-DED.

OBJECTIVE To establish HPLC fingerprint of Shuangdong capsules， and to study the spectral effect relationship of its anti-inflammatory effect. METHODS The fingerprints of 15 batches of Shuangdong capsules were established by HPLC，and the similarity evaluation was carried out； the foot swelling model was established to investigate the anti-inflammatory activity of Shuangdong capsules. The gray correlation analysis method was used to construct the spectral effect relationship for the anti- inflammatory effect of Shuangdong capsules using the swelling rate of rat foot and the levels of malondialdehyde （MDA）， superoxide dismutase （SOD）， prostaglandin E2 （PGE2）， interleukin-6 （IL-6）， IL-8， IL-1β and tumor necrosis factor-α （TNF-α） in right hindfoot tissues as the pharmacodynamic indexes of anti-inflammatory effects. RESULTS Overall 15 batches of Shuangdong capsules identified 20 common peaks， the similarities were all greater than 0.97， and a total of 8 chromatographic peaks were identified. According to the gray correlation analysis， the correlation degrees between the peak area and the foot swelling rate and the levels of MDA， SOD， PGE2， IL-6， IL-8， IL-1β and TNF-α in 15 batches of Shuangdong capsules were 0.621 1- 0.783 5， 0.564 3-0.827 9， 0.581 0-0.845 3， 0.564 9-0.855 0， 0.583 1-0.856 4， 0.576 5-0.863 5， 0.564 1-0.838 0 and 0.572 5- 0.851 3， respectively. Among them， the chemical components represented by peak 4 （geniposidic acid）， peak 10 （chlorogenic acid） and the chemical composition represented by peak 2 were strongly correlated with anti-inflammatory efficacy indicators. CONCLUSIONS In this study， HPLC fingerprints of 15 batches of Shuangdong capsules were successfully established. Among them， geniposidic acid， chlorogenic acid may be its anti-inflammatory ingredients.

Objective:This study aims to analyze the clinical characteristics of elderly patients with lung adenocarcinoma and to construct a predictive model for assessing their survival.Methods:We conducted a retrospective analysis of clinical data sourced from the SEER database for patients aged 60 years or older who were diagnosed with lung adenocarcinoma between 2013 and 2018.Cox regression analysis was employed to identify independent prognostic factors affecting the survival of elderly lung adenocarcinoma patients, leading to the development of a nomogram model.The discriminative ability and calibration of the nomogram were assessed using the C-index and calibration curve.Each patient's total risk score was calculated based on the predictive model, and patients were stratified according to the quartiles of their total risk scores.The Kaplan-Meier method and Log-rank test were utilized to evaluate survival differences among the identified risk groups.Results:Among 38, 852 lung adenocarcinoma patients, 17, 200 were males and 21, 652 were females.Significant differences in survival rates were observed among lung adenocarcinoma patients based on age, gender, marital status, histological grade, TNM stage, tumor size, and the presence of bone, brain, or liver metastases, as well as the type of treatment received, including surgical treatment, radiation therapy, and chemotherapy(all P<0.001).The C-index of the training model was 0.815(95% CI: 0.811-0.819), while the validation model yielded a C-index of 0.810(95% CI: 0.804-0.816).The prediction model demonstrated higher Area Under Curve(AUC)values of 0.746, 0.768, and 0.775 for 1-year, 3-year, and 5-year survival in the modeling dataset, respectively, and 0.747, 0.770, and 0.777 in the validation dataset.Furthermore, the risk stratification model effectively distinguished patients at varying levels of risk( P<0.001). Conclusions:Age, gender, marital status, histological grade, TNM stage, tumor size, and the presence of bone, brain, and liver metastases, along with treatment modalities such as surgery, radiotherapy, and chemotherapy, were identified as independent prognostic factors for elderly patients with lung adenocarcinoma.The risk prediction model developed in this study effectively differentiates between patients at varying levels of risk, which holds significant implications for predicting treatment responses in elderly lung adenocarcinoma patients and advancing the practice of precision medicine.
