Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

Microbial communities such as those residing in the human gut are highly diverse and complex, and many with important implications for health and diseases. The effects and functions of these microbial communities are determined not only by their species compositions and diversities but also by the dynamic intra- and inter-cellular states at the transcriptional level. Powerful and scalable technologies capable of acquiring single-microbe-resolution RNA sequencing information in order to achieve a comprehensive understanding of complex microbial communities together with their hosts are therefore utterly needed. Here we report the development and utilization of a droplet-based smRNA-seq (single-microbe RNA sequencing) method capable of identifying large species varieties in human samples, which we name smRandom-seq2. Together with a triple-module computational pipeline designed for the bacteria and bacteriophage sequencing data by smRandom-seq2 in four human gut samples, we established a single-cell level bacterial transcriptional landscape of human gut microbiome, which included 29,742 single microbes and 329 unique species. Distinct adaptive response states among species in Prevotella and Roseburia genera and intrinsic adaptive strategy heterogeneity in Phascolarctobacterium succinatutens were uncovered. Additionally, we identified hundreds of novel host-phage transcriptional activity associations in the human gut microbiome. Our results indicated that smRandom-seq2 is a high-throughput and high-resolution smRNA-seq technique that is highly adaptable to complex microbial communities in real-world situations and promises new perspectives in the understanding of human microbiomes.

Objective:To explore the short-term clinical effects of deep cervical lymph node-venous anastomosis in the treatment of Alzheimer’s disease (AD).Methods:A prospective exploratory study was conducted on the treatment of AD patients using the cervical deep lymph node-venous anastomosis technique in Scar and Wound Treatment Department, Plastic Surgery Hospital, Chinese Academy of Medical Sciences, from September to October 2024. The patients underwent high-frequency ultrasound to locate deep cervical lymph nodes and the external jugular vein. Under general anesthesia, bilateral deep cervical lymph node-venous anastomoses were performed. Indocyanine green (ICG) lymphography was conducted via subcutaneous injection behind the ear to visualize lymph nodes in levels Ⅱ and Ⅲ. After making a skin incision along the posterior margin of the sternocleidomastoid muscle, the external jugular vein, internal jugular veins, and associated lymph nodes were exposed. Adjacent veins were selected for anastomosis of lymph node. Using microsurgical techniques, end-to-side or end-to-end anastomosis was completed for lymph nodes in levels Ⅱ and Ⅲ. Preoperative assessments included the mini-mental state examination (MMSE, a higher score indicates better cognitive function), Alzheimer’s disease assessment scale-cognitive subscale (ADAS-Cog, a higher score indicates greater impairment of cognitive function), Alzheimer’s disease cooperative study scale for activities of daily living (ADCS-ADL, a higher score indicates better ability to perform daily activity), and neuropsychiatric inventory (NPI, a higher score indicates more severe behavioral and emotional symptom). Postoperative follow-up included the same scales to observe changes in cognitive function, activities of daily living, and emotional communication.Results:Four patients (1 male, 3 females, aged 58-79 years) with AD were included. All were diagnosed based on cerebrospinal fluid biomarkers. All patients successfully underwent bilateral deep cervical lymph node-venous anastomoses. On average, 4.3 (2-7 per person) anastomoses were performed per patient. Surgical procedures lasted an average of 6.5 h (5.5-8.5 h) with minimal blood loss (less than 50 ml). Patients resumed normal activity within 6 hours postoperatively and were discharged after an average of 4.1 d (3.5-5.0 d). Postoperative complications included one case each of aspiration pneumonia, lower limb venous thrombosis, and transient delirium, all of whom resolved without long-term effects. Clinical symptoms, including memory decline, mood swings, and anxiety, showed varying degrees of improvement. Patients reported enhanced quality of life, emotional stability, and social engagement, confirming the procedure’s safety and potential cognitive benefits. At one month postoperatively, the MMSE scores of the four patients increased by an average of 0.8 points compared to preoperative levels. Additionally, the two patients who completed the ADAS-Cog assessments showed a decrease in their scores (reduced by 1.0 points and 11.3 points, respectively, compared to preoperative scores), indicating a certain degree of improvement in cognitive function during this period. The ADCS-ADL and NPI scores of four patients varied significantly, without showing any clear pattern.Conclusion:Lymphovenous anastomosis of the deep cervical lymph node-venous anastomosis may provide a new surgical intervention approach for AD, but further large-scale studies and long-term follow-up are needed to validate its safety and effectiveness.

ObjectiveTo investigate the biological function and molecular mechanism of long non-coding RNA Linc‑pint in colorectal cancer. MethodsQuantitative real‑time quantitative （qRT‑PCR） was performed to detect the expression level of Linc‑pint in 31 pairs of colorectal cancer tumor and adjacent normal tissues； correlation between the expression level of Linc‑pint and the clinicopathological characteristics was analyzed by the chi‑square test. Kaplan-Meier survival analysis was used to assess the relationship between Linc‑pint expression level and the prognosis of patients. Cox regression model was used to analyze the relationship between clinicopathological characteristics and the prognosis of patients. Expression level of Linc‑pint were detected by qRT‑PCR in 5 common colorectal cancer cell lines. Effect of Linc‑pint on cell proliferation， invasion and migration was measured by cell counting kit‑8 assay， Transwell assay and harvested xenografts from nude mice. qRT‑PCR was performed to detect the expression level of Linc‑pint's target gene micro RNA（miR）‑21 in 31 pairs of colorectal cancer tumor tissues and adjacent normal tissues. Pearson correlation coefficient was used to assess the correlation between Linc‑pint and miR‑21. qRT‑PCR was used to detect the expression of overexpression of Linc‑pint on miR‑21 in colorectal cancer cells. ResultsExpression level of Linc‑pint in normal tissues （3.95±1.16） was significantly higher than that in colorectal cancer tissues （2.74±0.95） （t=6.17， P<0.05）. Overall survival rate of patients with high expression of Linc‑pint was 62.5%， which was significantly higher than that of patients with low expression of Linc‑pint （34.3%， P<0.05）. The proliferation， invasion and migration of CRC cells were inhibited after overexpression of Linc‑pint. In colorectal cancer tumor and adjacent normal tissues， Linc‑pint and miR‑21 showed opposite expression in tumor tissues and were negatively correlated （r=-0.288 and -0.908， both P<0.05）. ConclusionLinc‑pint acts as a tumor suppressor by down‑regulating the expression level of miR‑21 to inhibit the proliferation， invasion and migration of colorectal cancer.

Objective: To investigate the effect of LncRNA OIP5-AS1 on radiosensitivity of non-small cell lung cancer (NSCLC) cells and its mechanism. Methods: The radiation-resistant cell A549R was established by using A549 cells irradiated by X-ray 6Gy in 5 fractions. The expression levels of OIP5-AS1 and miR-34c-5p in A549 and A549R cells were detected by qRT-PCR. OIP5-AS1 inhibitor or miR-34c-5p mimetic was transfected into A549R cells, or OIP5-AS1 overexpression plasmid was transfected into A549 cells. Cell apoptosis was detected by flow cytometry. Cell radiosensitivity was analyzed by colony formation assay. The expression levels of p-Chk2 and p-ATM proteins were measured by Western blot. Dual luciferase assay was adopted to verify the relationship between OIP5-AS1 and miR-34c-5p. Results: Compared with A549 cells, the expression of OIP5-AS1 was significantly up-regulated in A549R cells (1.97±0.11 vs.1.01±0.05, P<0.05), whereas the expression of miR-34c-5p was remarkably down-regulated (0.43±0.02 vs.1.02±0.06, P<0.05). The expression levels of p-Chk2 and p-ATM proteins in A549R cells in the silencing OIP5-AS1+ 6Gy group were significantly lower (0.43±0.03 vs.1.39±0.15, 0.51±0.0 5 vs.1.21± 0.11, both P<0.05), whereas the apoptotic rate was significantly higher than those in the silencing control+ 6Gy group [(13.29±1.25)% vs. (28.47±2.31)%, P<0.05)]. The expression levels of p-Chk2 and p-ATM proteins in A549 cells in overexpressing OIP5-AS1+ 6Gy group were significantly higher than those in overexpression control+ 6Gy group (1.23±0.13 vs.0.75±0.06, 1.08±0.11 vs.0.59±0.04, both P<0.05). Inhibiting miR-34c-5p expression reversed the effect of silencing OIP5-AS1 on survival fraction of A549R cells (SER=1.42). OIP5-AS1 negatively regulated the expression of miR-34c-5p. Conclusion Silencing OIP5-AS1 enhances the radiosensitivity of radiation-resistant A549 cells by up-regulating the expression of miR-34c-5p, providing a potential target for radiotherapy of NSCLC cells.

Objective To investigate the relationship between the systolic/diastolic orthostatic hypotension(OH S/OH-D) and myocardial infarction (MI) in the elderly.Methods 200 subjects without myocardial infarction (MI) aged 60 years and over in our urban district were selected.The orthostatic and supine blood pressure and heart rate were measured in supine position after resting for more than 5 minutes and at 0 and 2 minutes after standing.All eases were divided into systolic orthostatic hypotension(OH-S)or diastolic orthostatic hypotension(OH-D)groups based on the results of orthostatic hypotension,and followed up by telephone with mean period of 325 days.The primary endpoint was MI occurrence for analyzing the correlation between OH-S/OH-D and MI incidence.Results The prevalence rate of OH in this cohort was 38％,with OH-S 20％ and OH-D 18％.In the very elderly group(≥80 years)versus the elderly group,the occurrences of 0H and OH-S were(27％ vs.21 ％,P =0.036;22 ％ vs.15 ％,P =0.020),respectively,while no significant difference was found in OH-D between the two groups.After 325 day follow up,the prevalence of MI was significantly(P＜ 0.05)higher in the OH positive subjects than in the 0H negative subjects,which result was the same as the prevalence of MI in OH-S or and OH-D group.After adjusting for age,supine blood pressure,creatinine and cerebrovascular history,logistic regression analysis showed that MI was correlated with OH(HR 15.72,95％CI 3.29～74.23,P=0.002),OH-S(HR 8.552,95％CI 2.51～30.21,P=0.004)and OH-D(HR 3.80,95 ％CI 1.14～13.80,P=0.042).Compared with OH-D,OH-S had more significant correlation with MI.Conclusions Orthostatic hypotension,particularly systolic orthostatic hypotension,is common in elderly patients.The OH-S and OH-D have a significant correlation with MI.

Objective To investigate the changes in serum matrix metalloproteinase(MMP)-2 and MMP-9 and their relationship with serum B-type brain natriuretic peptide(BNP)in patients with chronic heart failure.Methods MMP-2,MMP-9 and serum BNP levels were measured in 184 patients with chronic heart failure and 61 healthy controls.The relationship between changes in MMP-2 and-9 and serum BNP was analyzed.Results Chronic heart failure was categorized into grade Ⅱ,Ⅲ and Ⅳ according to NYHA.In grade Ⅱ,Ⅲ and Ⅳ and the control group,the levels of MMP-2 were(309.1±60.1)nmol/L,(422.6±89.6)nmol/L,(694.8±126.2)nmol/L and(217.2±26.3)nmol/L respectively,and the levels of MMP-9 were (321.2±63.2)nmol/L,(454.4±96.3)nmol/L,(634.1±51.2)nmol/L and(210.8±23.6)nmol/L respectively.The levels of MMP-2 and MMP-9 were significantly higher in chronic heart failure subgroups than in the control group(F=3.65,12.52;P=0.000,0.000).According to the pairwise comparison among the chronic heart failure subgroups,the levels of serum MMP-2 and MMP-9 were significantly higher in NYHA Ⅳ grade than in NYHA Ⅲ grade,and higher in NYHA Ⅲ grade than in NYHA Ⅱ grade(all P<0.05).In patients with chronic heart failure groups,MMP-2 was positively correlated with serum BNP(r=0.866,P=0.000),and with MMP-9(r=0.516,P=0.001).Conclusions MMP-2 and MMP-9 levels might be closely correlated with chronic heart failure and show an upward trend with the progression of chronic heart failure.The levels of MMP-2 and MMP-9 are associated with BNP,which indicates that clinical monitoring of the serum level changes can provide a certain reference for diagnosis,treatment and prognosis in patients with chronic heart failure.

Objective: To explore the clinical response on cardiac resynchronization therapy (CRT) in patients of chronic heart failure (CHF) with different QRS wave morphology. Methods: A total of 52 CHF patients received CRT in our hospital and the Seventh People's Hospital of Zhengzhou City from 2010-03 to 2013-07 were retrospectively studied. The patients were divided into 3 groups: True-complete left bundle branch block (t-CLBBB) group,n=20, Classic LBBB (CLBBB) group,n=15 and IVCD group,n=17. The general clinical condition, the indexes of echocardiography at 6 months of follow-up study including left ventricular end diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), NYHA classiifcation and 6-MWT were examined and compared among different groups. Results: In general clinical condition, the ratio of non-ischemic heart disease patients in t-CLBBB group was higher than those in CLBBB group and IVCD group, allP<0.05. By 6 months follow-up study, LVEDD in t-CLBBB group (62.6 ± 8.9) mm was lower than those in CLBBB group (70.0 ± 8.9) mm and IVCD group (72.8 ± 8.0) mm, LVEF was higher in t-CLBBB group (38.5 ± 6.2) % than those in CLBBB group (31.7 ± 6.7) % and IVCD group (30.1 ± 6.7) %. NYHA classiifcation in t-CLBBB group (2.00 ± 0.45) grade was lower than those in CLBBB group (2.73 ± 0.80) grade and IVCD group (3.12 ± 0.78) grade . 6-MWT in t-CLBBB group (302.0 ± 57.9) m was longer than those in CLBBB group (257.3 ± 59.0) m and IVCD group (220.2 ± 57.9) m, allP<0.05. Conclusion: CRT is an effective method for treating CHD patients, different QRS morphology may have different response, the patients with t-CLBBB would make better response.

Objective: To evaluate the short-term effect of thrombus aspiration catheters combining tiroifban medication for myocardial tissue reperfusion recovery in patients with acute ST-elevation myocardial infarction (STEMI).
Methods: A total of 105 STEMI patients with percutaneous coronary intervention (PCI) in our hospital from 2011-05 to 2013-05 were studied, there were 73 male and 32 female with the mean age of (58.39 ± 10.37) years. The patients were randomly divided into 2 groups, Group A, the patients received thrombus aspiration catheters with intravenous tiroifban, n=53 and Group B, the patients received tiroifban and PCI, n=52. The basic clinical features, myocardial tissue perfusion level, major adverse cardiovascular events (MACE) at post operative and in-hospital period were recorded, the cardiac function was examined by echocardiography at 6 months after PCI in both groups.
Results: The basic clinical features were similar between 2 groups. The thrombolysis in myocardial infarction trial (TIMI) 3 lfow rate was higher in Group A than that in Group B (92.45% vs 55.77%), P=0.000. TIMI 2 and TIMI 0~1 lfow rates were lower in Group A than that in Group B (7.55%vs 26.92%), P=0.008 and (0%vs 17.31%), P=0.002. The adjusted TIMI frame was lower in Group A (27.26±5.50) vs (38.98±5.42), P<0.001. The echocardiography at 6 months after PCI indicated that Group A had higher LVEF than that in Group B (0.55±0.06) vs (0.47±0.06), P<0.001;lower left ventricular end diastolic diameter (50.77±5.45) vs (54.76±5.34), P<0.001;less angina and target vessel revascularization (16.98%vs 40.38%), P=0.008 and (9.43%vs 17.31%), P=0.008. The incidence of MI, acute heart failure, cardiac death and non-target vessel revascularization were similar between 2 groups, P>0.05.
Conclusion:Thrombus aspiration catheters combining tiroifban medication may obviously improve the myocardial tissue reperfusion and the short-term cardiac function in STEMI patients after PCI, it could reduce the incidence of no-relfow without increasing MACE.
