Functional dyspepsia （FD） is a prioritized disease category where traditional Chinese medicine （TCM） demonstrates distinct therapeutic advantages. The current western medicine treatment for FD is mainly based on proton pump inhibitors and prokinetic agents， with digestive enzymes， probiotics and antidepressants serving as adjuvant medication， yet such therapies still have certain limitations. TCM treatment for FD includes oral administration of Chinese herbal formulas and Chinese patent medicines， as well as external TCM therapies such as acupuncture and moxibustion， acupoint application， hot medicinal compress therapy， rubbing with ointment， medicinal iontophoresis， auricular acupoint therapy and tui na （Chinese medical massage）. The combined treatment of FD with integrated TCM and western medicine can significantly improve clinical effectiveness and reduce adverse reactions. The common mechanisms underlying the therapeutic effects of both TCM and western medicine revolve around the core pathological processes of FD， mainly focusing on restoring gastrointestinal motility， regulating the levels of brain-gut peptides， modulating intestinal microecology， and ameliorating inflammatory status. The differential mechanisms lie in the precise targeting feature of western medicine versus the holistic-regulating and multi-target characteristics of TCM， and the two approaches exert a synergistic effect to enhance efficacy. This paper proposes to leverage the advantages of TCM in holistic regulation and the strengths of western medicine in targeted treatment， so as to provide personalized and comprehensive treatment regimens for FD patients.

Gastric cancer is a high-incidence malignancy that poses a serious threat to public health in China, ranking among the top three cancers in both incidence and mortality. The majority of patients are diagnosed at an advanced stage, resulting in limited treatment options and poor prognosis. To address key challenges in gastric cancer diagnosis and treatment, a research team led by Professor Jiafu Ji at Peking University Cancer Hospital has focused on the project "Development and Dissemination of Precision Medicine Approaches in Gastric Cancer Management". Through a series of high-quality multicenter clinical studies, the team established a set of new international standards in perioperative treatment, individua-lized drug selection, intelligent noninvasive diagnostics, and novel immunotherapy strategies. These advances have significantly improved treatment efficacy and reduced surgical trauma, achieving key technological breakthroughs in diagnosis, therapy, and mechanistic understanding, and systematically enhancing outcomes for gastric cancer patients. The project ' s findings had a broad international impact, including hosting China ' s first International Gastric Cancer Congress. Through nationwide dissemination, they have promoted the development of precision diagnosis and treatment of gastric cancer as a discipline, and led the formulation of the National Health Commission's guidelines for gastric cancer diagnosis and treatment. In recognition of its achievements, the project was awarded the First Prize of the 2024 Chinese Medical Science and Technology Award.

OBJECTIVE: To observe the clinical efficacy of acupoint thread-embedding therapy of regulating governor vessel, dispersing lung, and suppressing reflux for gastroesophageal reflux cough (GERC). METHODS: A total of 120 GERC patients were randomly assigned to an observation group (60 cases, 1 case dropped out) and a control group (60 cases, 1 case was eliminated). The observation group received acupoint thread-embedding treatment at positive response points of governor vessel. If no such points were detected, the following acupoints were used: Dazhui (GV14), Fenghu (Extra), Shendao (GV11), Lingtai (GV10), and Zhiyang (GV9). Treatment was administered once every two weeks. The control group received oral rabeprazole enteric capsules at 20 mg twice daily. All the treatment was given for 6 weeks. Clinical outcomes were assessed using cough symptom score, reflux disease questionnaire (RDQ) score, and Leicester cough questionnaire (LCQ) score before and after treatment in the two groups. Clinical efficacy was also compared between the two groups. RESULTS: After treatment, both groups showed decreased cough symptom scores and the each item scores and total scores of RDQ (P<0.001), and increased LCQ scores (P<0.001) compare with those before treatment. The observation group exhibited lower cough symptom score and chest pain, reflux and total score of RDQ, and higher LCQ score compared to those in the control group (P<0.05). The total effective rate in the observation group was 94.9% (56/59), which was higher than 84.7% (50/59) in the control group (P<0.05). CONCLUSION Acupoint thread-embedding therapy of regulating governor vessel, dispersing lung, and suppressing reflux could effectively alleviate cough and reflux symptoms in patients with GERC and improve their quality of life.

Objective To analyze the distribution and drug resistance patterns of pathogenic bacteria in bile and blood cultures obtained from patients with biliary stones accompanied by acute biliary tract infection,to evaluate the clinical appropriate-ness of antibiotic use based on drug sensitivity results,and to provide evidence for empirical antibiotic treatment in such patients.Methods The clinical data of 161 patients with biliary calculi complicated by acute biliary tract infection who were admitted to the First People's Hospital of Neijiang from 2017 to 2023 were retrospectively analyzed.The results of microbial culture,drug sensitivity analysis,and patient characteristics were assessed to evaluate the appropriateness of clinical antimicrobial therapy.Results Among the 161 patients with positive cultures,212 strains of pathogenic bacteria were detected.The predominant patho-gens were Escherichia coli,Klebsiella pneumoniae subspecies,and Enterococcus faecium.Age and underlying diseases significantly affected the distribution of Escherichia coli and Klebsiella pneumoniae subspecies.Within the gram-negative bacterial group,Esche-richia coli and Klebsiella pneumoniae subspecies exhibited higher drug resistance to commonly used broad-spectrum penicillin,third-generation cephalosporin and quinolones but lower resistance rates to piperacillin and tazobactam;furthermore,elderly indi-viduals aged ≥65 years showed higher resistance rates to ceftriaxone than those under age 65 while people with drug exposure history had higher ceftazidime resistance rates that were statistically significant.In contrast to Enterococcus faecalis which displayed low antimicrobial resistance rates for most drugs tested in this study,Enterococcus faecium demonstrated high levels of antibiotic resistance;however,both Enterococcus faecalis and Enterococcus faecium exhibited zero-resistance rates against vancomycin and tigecycline although this may be attributed to their small sample size in our study cohort.Finally,we found that empirical anti-in-fective drugs,as well as target anti-infective drugs,were not prescribed rationally among these patients due mainly to inappropriate combinations of antibiotics or incorrect dosages.Conclusions The predominant pathogens in patients with acute biliary tract infection are gram-negative bacteria,Gram-positive bacteria,and fungi;however,the potential involvement of anaerobic bacteria should not be overlooked.Vancomycin exhibits sensitivity against gram-positive bacteria,yet the overall rationality of antibiotic usage remains suboptimal.Enhanced clinical testing for pathogenic microorganisms is imperative in the management of biliary stones accompanied by acute biliary tract infection.In contrast,clinical pharmacists should provide comprehensive training on anti-infective drugs to clinicians to facilitate their judicious selection of antibiotics based on drug sensitivity results and prevent the e-mergence of multidrug-resistant bacteria.

Objective:To prepare a monoclonal strain of mumps virus of genotype F，which is intended to be applied as a national standard strain，and to provide corresponding virus strain resources for the surveillance，prevention and control of mumps.Methods:The plaque purification technique was used to pick monoclonal strains on Vero/hSLAM cells. The biological characteristics and stability of the monoclonal virus strains were evaluated by observing the cytopathic effect of the monoclonal virus strains，morphological observation of virological characteristics，determination of virus titer and whole-genome sequencing，and mycoplasma detection.Results:After infection of Vero/hSLAM cells，the monoclonal strain of mumps virus constructed after plaque purification could cause cell fusion. Under the negative staining electron microscope，the virus particles were spherical，with a diameter between 100 and 200 nm，and had an obvious envelope. The virus titer of the 2 nd to 6 th generations was between 10 6 and 10 7 TCID 50/ml. Through whole-genome sequencing and phylogenetic analysis，the full length of the virus genome sequence was obtained as 15 384 bp，and it was confirmed that the monoclonal virus strain was of genotype F. The nucleotide difference rate between the 2 nd and 6 th generations was 0.013%. Conclusion:The monoclonal strain of mumps virus constructed in this experiment has typical cytopathic effects and typical morphological structures. The virus has good activity and stable genetic characteristics，and can be used as a candidate strain for application as a national standard strain. It can be used for reagent research and development，evaluation of immunization effects，and other subsequent work.

A 36-year-old male presented to the Department of Neurosurgery of the Second People′s Hospital of Hunan Province on February 12, 2024, due to "10 days of aggravated paroxysmal headache and 1 day of mental abnormality". Ten days ago, after catching a cold, the patient developed persistent low fever and paroxysmal headache. On February 12, 2024, acuted mental and behavioral abnormalities developed, including slow response, self-talk, defecation and urination, no sense of shame and other mental and behavioral abnormalities. On February 22nd, metagenomic next-generation sequencing (mNGS) in cerebrospinal fluid confirmed feline rickettsia infection. One week after doxycycline anti-rickettsia treatment, cerebrospinal fluid mNGS results indicated that the etiology turned negative, and the clinical symptoms improved. Mental disorders caused by rickettsial encephalitis in cats are rare but clinically significant. This case highlights the diagnostic value of mNGS in critical and difficult cases, and supports its integration with traditional diagnostic techniques to achieve precision medicine.

Phages, as obligate bacterial and archaeal parasites, constitute a virus group of paramount ecological significance due to their exceptional abundance and genetic diversity. These biological entities serve as critical regulators in Earth's ecosystems, driving biogeochemical cycles, energy fluxes, and ecosystem services across terrestrial and marine environments. Within soil microbiomes, phages function as microbial "dark matter," maintaining the soil-plant system balance through precise modulation of the microbial community structure and functional dynamics. Despite the growing research interests in soil phages in recent years, the proportion of such studies in environmental virology remains disproportionately low, which is primarily attributed to researchers' limited familiarity with the research methodologies for phage microecology, incomplete technical frameworks, and inherent challenges posed by soil environmental complexity. To address these challenges, this review synthesizes cutting-edge methodologies for soil phage investigation from four aspects: (1) tangential flow filtration (TFF)-based phage enrichment strategies; (2) integrated quantification approaches combining double-layer agar plating, epifluorescence microscopy, and flow cytometry; (3) multi-omics analytical pipelines leveraging metagenomics and viromics datasets; and (4) computational frameworks merging machine learning algorithms with eco-evolutionary theory for deciphering phage-host interaction networks. Through comparative analysis of methodological principles, technical merits, and application scopes, we establish a comprehensive workflow for soil phage research. Future research in this field should prioritize: (1) construction of soil phage resource libraries, (2) exploration of RNA phages based on transcriptomes, (3) functional characterization of unknown genes, and (4) deep integration and interaction validation of multi-omics data. This systematic methodological synthesis provides critical technical references for addressing fundamental challenges in characterizing soil phages regarding the community structure, functional potential, and interaction mechanisms with hosts.

Objective To explore the mechanism by which Liqi Huoxue Dripping Pill(LQHXDP)inhibits cardiomyocyte apoptosis in rats with myocardial ischemia-reperfusion injury(MIRI).Methods Male Sprague-Dawley(n=96)rats were randomly assigned to a normal,sham-operated,model,LQHXDP,adenovirus negative control(Ad-shNC),adenovirus-mediated HIF-1α knockdown(Ad-shHIF-1α),LQHXDP+Ad-shNC,or LQHXDP+Ad-shHIF-1α group using a random number table.LQHXDP was administered daily via oral gavage at 175.0 mg/(kg·d)for 10 consecutive days.On day 7,recombinant adenovirus was injected into the left ventricular wall of rats in the corresponding groups at multiple points.On day 10,the MIRI model was established by ligating the left anterior descending coronary artery.The sham-operated group underwent thoracotomy and suture placement without coronary ligation.Samples were collected after reperfusion was completed.Serum creatine kinase isoenzymes(CK-MB),cardiac troponin I(cTnI),and heart-type fatty acid binding protein(H-FABP)levels were measured using enzyme-linked immunosorbent assay.2,3,5-Triphenyltetrazolium chloride staining was used to measure the volume ratio of myocardial infarction.HE staining was performed to observe the morphology of myocardial tissue.Terminal transferase uridyl nick end labeling assay was conducted to analyze the apoptosis rate of cardiomyocytes,and Western blotting was used to detect the expression of key proteins in the apoptosis(B-cell lymphoma-2[Bcl-2],Bcl-2 associated X protein[Bax],and cleaved cysteinyl aspartate specific proteinase 3[Cleaved-Caspase-3]and HIF-1α/Bcl-2-adenovirus E1B 19 kDa interacting protein 3(BNIP3)signaling pathway(HIF-1α,heme oxygenase-1[HO-1],and BNIP3).Results LQHXDP pretreatment significantly reduced serum CK-MB,cTnI,and H-FABP levels,as well as the myocardial infarction volume ratio in rats with MIRI.LQHXDP also improved myocardial tissue morphology,decreased cardiomyocyte apoptosis,upregulated Bcl-2 protein expression,and downregulated Bax,Cleaved-Caspase-3,HIF-1α,HO-1,and BNIP3 protein expressions(P<0.05).However,adenovirus-mediated shRNA HIF-1α impaired the effects of LQHXDP pretreatment in attenuating myocardial injury and inhibiting apoptosis in MIRI rats(P<0.05).Conclusion LQHXDP reduces cardiomyocyte apoptosis and protects rat myocardium from MIRI by regulating the HIF-1α/BNIP3 signaling pathway.
