ObjectiveThis study focused on the marketed Chinese patent medicines for the treatment of Functional Diarrhea （FDr） in China and their prescription characteristics， in order to provide support for the clinical application and research and development of anti-FDr Chinese patent medicines. MethodsCollect the information of Chinese patent medicines that have been marketed to treat FDr， use Microsoft Excel 2021 software to conduct preliminary data collation and statistical analysis， and use the ancient and modern medical record cloud platform （V2.3.9） to analyze the standardized Chinese patent medicine prescriptions from the aspects of drug nature and taste， medication characteristics and prescription rules. Results147 kinds of FDr Chinese patent medicines were included in this study. There are a total of 40 varieties of FDr Chinese patent medicines suitable for children； The distribution of dosage forms is mainly pills， tablets， and capsules. 110 prescriptions were screened， among which the proportion of Chinese patent medicines for the treatment of spleen deficiency syndrome was the highest； The top three drug use frequency were licorice， Atractylodes macrocephala， and Poria cocos； The medicinal properties are mainly warm and flat， and the medicinal taste is mostly pungent， sweet and bitter， and most of them belong to the two meridians of the spleen and stomach； The association rules analysis obtains 20 strong association pairing sets； Three drug combinations were obtained by cluster analysis. ConclusionFDr Chinese patent medicine shows unique value in clinical application， especially in the field of children. However， there are still problems such as strong professionalism in the indication expression of drug instructions， limited coverage of the medical insurance catalog， and lack of high-level evidence-based medicine and pharmacoeconomic evidence. To this end， in the future， efforts should be made to build a multi-level evidence-based evidence system， improve medication compliance， and deepen research on syndrome-based medication laws， so as to enhance the clinical application value and scientific connotation of FDr Chinese patent medicines.

Objective: To investigate the relationship between physical development indicators and the onset and progression of myopia among children and adolescents, so as to provide theoretical support for coordinated vision and physical health management. Methods: A prospective cohort study was conducted. In September 2022, 3 102 students from grade one in primary school to grade three in junior high school (five year primary school and four year junior high school) from six schools in Huantai County, Shandong Province, were selected using multistage cluster random sampling method to participate in an epidemiological survey on myopia, with follow up completed in September 2023. Follow up value minus baseline value( d ) was used to assess changes in physical development and vision indicators. Multivariate Logistic regression analysis was used to examine the relationship between physical development indicators and the incidence of myopia. Generalized linear models were established to analyze the relationship between physical development indicators and changes in d spherical equivalent (SE) and d axial length (AL) . Results: Multivariate Logistic regression analysis showed that, after adjusting for factors such as gender, age, and baseline body mass index, the third ( Q 3)and fourth ( Q 4)quartiles of d height showed increased risks of myopia onset within one year compared to the first quartile( Q 1) ( OR =1.85,95% CI =1.18-2.88; OR =1.74,95% CI =1.09-2.78,both P ＜0.05). Results from the generalized linear model indicated that, after adjusting for confounding factors such as gender, age, and baseline SE, d SE was negatively correlated with d height and d weight in children and adolescents ( β =-0.024, 95% CI =-0.031 to -0.018; β =-0.006, 95% CI =-0.011 to -0.001), d AL was positively correlated with d height and d weight in children and adolescents ( β =0.011, 95% CI =0.008-0.013; β =0.005, 95% CI =0.003-0.007) (all P ＜0.05). Conclusions Physical development indicators in children and adolescents were associated with the onset and progression of myopia. Dynamic monitoring and early intervention of myopia should be strengthened for children and adolescents with rapid height and weight gain to achieve coordinated management of myopia and physical development.

To systematically analyzed the reporting status of core elements in publicly available clinical practice guideline(hereafter referred to as "guideline") protocols published domestically and internationally over the past decade, identified existing problems, and provided evidence to inform the standardized writing and publication of future guideline protocols.

Oral squamous cell carcinoma (OSCC) is a common head and neck malignancy. Approximately 50% to 60% of patients with OSCC are diagnosed at a locally advanced stage (clinical staging III-IVa). Even with comprehensive and sequential treatment primarily based on surgery, the 5-year overall survival rate remains below 50%, and patients often suffer from postoperative functional impairments such as difficulties with speaking and swallowing. Programmed death receptor-1 (PD-1) inhibitors are increasingly used in the neoadjuvant treatment of locally advanced OSCC and have shown encouraging efficacy. However, clinical practice still faces key challenges, including the definition of indications, optimization of combination regimens, and standards for efficacy evaluation. Based on the latest research advances worldwide and the clinical experience of the expert group, this expert consensus systematically evaluates the application of PD-1 inhibitors in the neoadjuvant treatment of locally advanced OSCC, covering combination strategies, treatment cycles and surgical timing, efficacy assessment, use of biomarkers, management of special populations and immune related adverse events, principles for immunotherapy rechallenge, and function preservation strategies. After multiple rounds of panel discussion and through anonymous voting using the Delphi method, the following consensus statements have been formulated: 1) Neoadjuvant therapy with PD-1 inhibitors can be used preoperatively in patients with locally advanced OSCC. The preferred regimen is a PD-1 inhibitor combined with platinum based chemotherapy, administered for 2-3 cycles. 2) During the efficacy evaluation of neoadjuvant therapy, radiographic assessment should follow the dual criteria of Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and immune RECIST (iRECIST). After surgery, systematic pathological evaluation of both the primary lesion and regional lymph nodes is required. For combination chemotherapy regimens, PD-L1 expression and combined positive score need not be used as mandatory inclusion or exclusion criteria. 3) For special populations such as the elderly (≥ 70 years), individuals with stable HIV viral load, and carriers of chronic HBV/HCV, PD-1 inhibitors may be used cautiously under the guidance of a multidisciplinary team (MDT), with close monitoring for adverse events. 4) For patients with a poor response to neoadjuvant therapy, continuation of the original treatment regimen is not recommended; the subsequent treatment plan should be adjusted promptly after MDT assessment. Organ transplant recipients and patients with active autoimmune diseases are not recommended to receive neoadjuvant PD-1 inhibitor therapy due to the high risk of immune related activation. Rechallenge is generally not advised for patients who have experienced high risk immune related adverse events such as immune mediated myocarditis, neurotoxicity, or pneumonitis. 5) For patients with a good pathological response, individualized de escalation surgery and function preservation strategies can be explored. This consensus aims to promote the standardized, safe, and precise application of neoadjuvant PD-1 inhibitor strategies in the management of locally advanced OSCC patients.

Health economics evidence plays an important role in linking clinical value evidence with health resource allocation decisions in the development of clinical practice guidelines. It can not only effectively balance clinical effectiveness and economic feasibility but also avoid forming "idealized" recommendations that are detached from the affordability of the healthcare system or the burden-bearing capacity of patients. To promote guideline developers to use health economics evidence more standardizedly and fully, this paper conducts an in-depth analysis of the current application status, existing challenges, access channels, and application processes of health economics evidence in current guidelines, and on this basis, puts forward considerations and suggestions for strengthening and standardizing the application of health economics evidence in China's clinical practice guidelines.

Objective To explore the role of chloride intracellular channel 5 (CLIC5) in the development of lung adenocarcinoma (LUAD). Methods The expression levels of CLIC5 in LUAD samples were determined using bioinformatics and qRT-PCR. The correlation between CLIC5 expression and LUAD progression was revealed through survival analysis and clinicopathological feature analysis. After the knockdown or overexpression of CLIC5 in the LUAD cells, cell proliferation was assessed through colony formation assay, cell apoptosis rate by flow cytometry, and cell migration and invasion by scratch and Transwell invasion assay. The protein levels of vimentin and Snail were detected by Western blot. Results Bioinformatics analysis results showed low CLIC5 expression levels in the LUAD samples. This finding was associated with the aggressive progression of LUAD and the poor survival of patients with LUAD. The qRT-PCR results confirmed that CLIC5 was mainly expressed in the cytoplasm of the LUAD cells. CLIC5 overexpression inhibited cell activity and proliferation and promoted the apoptosis of LUAD cells. The knockdown of CLIC5 exhibited the opposite effect. CLIC5 overexpression inhibited the migration and invasion of LUAD cells, downregulated Bcl-2, vimentin, and Snail and upregulated Bax, cleaved caspase-3 and E-cadherin in the LUAD cells. CLIC5 knockdown exhibited opposite effects. Conclusion CLIC5 overexpression promotes cell apoptosis and inhibits cell proliferation and invasion, thereby inhibiting the development of LUAD. Hence, CLIC5 is a novel biomarker of prognosis and therapeutic target for LUAD.

Objective To exple the mechanism of Qixiong Zuogui Granules(QXZG)for enhancing synaptic plasticity in aging rats.Method Forty SD rats were randomized into control group,aging model group,donepezil treatment group,and QXZG treatment group(n=10).Except for the control rats,all the rats were subjected to daily intraperitoneal injection of D-galactose for 8 consecutive weeks to induce brain aging,and donepezil hydrochloride and QXZG suspension were administered by gavage during modeling.After the interventions,the rats were evaluated for general conditions,behavioral changes,oxidative stress indicators,hippocampal pathologies,and expressions of the brain-derived neurotrophic factor(BDNF)/tyrosine kinase receptor B(TrkB)pathway,p16,and synaptic plasticity-associated proteins.Results The rats in the model group exhibited obvious aging phenotypes such as yellowing of the teeth and hair,body weight loss,and impaired learning and memory abilities,with decreased serum SOD and GSH-Px activities and increased serum MDA level.The rat models also showed obvious pathological changes,reduced Nissl bodies,and elevated p16 protein expression in the hippocampal CA1 region,with significantly decreased expression levels of BDNF,TrkB,CREB and synaptic plasticity proteins SYN,GAP43,and PSD95.Treatment with QXZG alleviated the aging phenotypes in the rat models,improved their learning and memory abilities and pathological changes in the hippocampal CA1 region,reduced oxidative stress and p16 protein expression,and promoted the expressions of the BDNF/TrkB pathway proteins and synaptic plasticity proteins.Conclusion QXZG enhances synaptic plasticity and reduces oxidative stress in aging rats possibly by upregulating the BDNF/TrkB signaling pathway proteins,thereby delaying brain aging and improving learning and memory abilities of the rats.

To understand the current epidemiological status and biological characteristics of avian paramyxoviruses(APMV)in wild birds in China,a total of 1 384 fecal samples of wild birds were collected in eight provinces(autonomous regions),including Ningxia,in 2023,to detect avian pa-ramyxovirus infections by viral isolation and RT-PCR.Positive samples were subjected to F gene sequence amplification and genetic evolutionary analyses.The results showed that 10 strains of APMV were isolated and identified from 1 384 wild bird feces samples with a positive rate of 0.72％.Out of the 10 strains,4 strains were APMV-1,which was in the same branch to the Ameri-can goose APMV-1 strain and had the homology ranging from 93％to 97.3％.Three strains of APMV-4 were in the same branch with the Russian duck APMV-4 strain and the Russian pintail APMV-4 strain,with homology ranging from 99.1％to 99.5％.Three strains were APMV-6,they were in the same branch with the Russian ruddy bladdered duck APMV-6 strain,with homology ranging from 98.7％to 99.20％.The intracerebral inoculatable pathogenicity index(ICPI)of the four strains for 1-day-old chicks ranged from 0 to 0.48,which was low in pathogenicity for chick-ens.The above results enriches the epidemiological information and the biological characteristics of avian paramyxovirus in wild birds in China,which provides a reference for the early warning,scien-tific prevention and control of this disease.

Objective:To investigate the predictive value of enhanced computed tomography (CT) combined with magnetic resonance imaging (MRI) examination on prognosis of clear cell renal cell carcinoma (ccRCC) and its correlation with clinical features. Methods:The postoperative follow-up data of enhanced CT and MRI of 80 patients with suspected (ccRCC) who admitted to Bozhou People's Hospital from March 2019 to May 2023 were selected,and they were divided into disease progression group (24 cases) and disease progression-free group (56 cases) according to the condition of disease progression. The disease progression of them were diagnosed through relevant examinations (collection of disease history,physical examination,enhanced CT,MRI,laboratory examination,pathological examination and so on). According to the information of clinical imaging,the age,gender,tumor diameter,with or without tumor thrombus,the location of tumor and surgical method were used to conduct single factor logistic regression analysis,so as to confirm independent predictors. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of enhanced CT combined with MRI to the prognosis of ccRCC. The Pearson linear correlation was adopted to analyze the correlation between the results of enhanced CT combined with MRI and prognosis. Results:Based on the results of the follow-up study,CT value of cortex phase,CT value of medullary phase and apparent dispersion coefficient (ADC) in the disease progression group were significantly smaller than those in the disease progression-free group,and the differences of them between two groups were statistically significant (t=10.610,4.697,2.901,P<0.05),respectively. The diffusion coefficient (K value) of disease progression group was significantly larger than that of disease progression-free group,and there was significant difference between the two groups (t=6.375,P<0.05),while there was no significant in diffusion rate (D) between the two groups (P>0.05). The area under curve (AUC) values of ROC curve of single enhanced CT examination,single MRI examination and the combined examination of them were larger than 0.5 in predicting the prognosis of ccRCC,which indicated that both the two examinations had a certain value in predicting the prognosis of ccRCC,and the AUC value of combined examination was the highest (0.940),which indicated the value of combined examination was the highest in predicting the prognosis of ccRCC. There were not significant differences in gender,surgical method,tumor thrombus and tumor location between the two groups (P>0.05). The age and tumor diameter of the disease progression group were significantly larger than those of the disease progression-free group (t=4.292,3.219,P<0.05),respectively. The results of the logistic regression analysis showed that the age and tumor diameter were respectively independent influencing factor on the prognosis of ccRCC (HR=2.167,0.689,P<0.05). The results of Pearson correlation analysis indicated that there was negative correlation between enhanced CT examination and prognosis (r=-0.65,P<0.05),and there was positive correlation between MRI examination and prognosis (r=0.72,P<0.05). In addition,there was a negative correlation in the results between enhanced CT examination and MRI examination (r=-0.58,P<0.05). Conclusion:The prediction of enhanced CT combined with MRI examination is higher than that of each single examination of them for the prognosis of ccRCC,and there is a certain correlation between that and clinical features,but it is still necessary to conduct comprehensive judgement after combines other influence factors in clinical practice.
