Respiratory syncytial virus(RSV)and the acute respiratory infections it induced have become a global key public health issue.However,the existing antiviral drugs are insufficient and have limitations such as drug resistance,limited applicability,and high toxic side effects,which urgently require the development of new therapeutic methods and drugs.As an important part of traditional medicine,traditional Chinese medicine(TCM)and its compound preparations have rich clinical accumulation and potential advantages in the field of antiviral therapy.Their unique targets and multi-link synergistic effects are highly compatible with the complex patho-genic network of RSV.The article aims to describe the infection pathway and key targets of RSV,summarize the progress and shortcom-ings of existing therapeutic methods,and systematically analyze the regulatory mechanism and drug potential of TCM and its compound preparations on different stages of viral infection,so as to provide reference for improving the prevention and control capabilities and de-veloping new antiviral drugs in China.

Intrahepatic cholangiocarcinoma(ICC)typically has an insidious onset,and most patients have already progressed to advanced stages by the time of initial diagnosis,missing the opportunity for radical surgery.Surgical treatment is the main approach for ICC,but the high early recurrence rate after surgery and poor prognosis remain significant challenges.In recent years,there have been continuous breakthroughs in chemotherapy,immunotherapy,targeted therapy,and combination therapies for ICC,ushering in a new era for systemic treatment.With the improvement of treatment effects,conversion therapy,and neoadjuvant therapy have emerged as prominent topics of interest.However,with the deepening of clinical diagnosis and treatment practices,complex and unresolved issues have gradually emerged,triggering extensive discussions among scholars at home and abroad.Currently,there is no clear,standardized diagnostic and therapeutic process for conversion therapy and neoadjuvant therapy in the guidelines of the National Comprehensive Cancer Network or the Chinese Society of Clinical Oncology.This article aims to comprehensively review the latest progress in neoadjuvant and conversion therapy for ICC and deeply explore the controversial focuses therein,with the expectation of providing useful references for clinical practice and promoting the further development of this field.

Background and Aims:Intrahepatic cholangiocarcinoma(ICC)is a highly malignant liver tumor,with an increasing incidence worldwide,particularly in Asia.Although radical surgical resection is currently the only potentially curative treatment,the high recurrence rate and low postoperative overall survival(OS)rate of ICC remain major clinical challenges.Adjuvant therapy(AT)and neoadjuvant therapy(NAT)are important strategies to reduce postoperative recurrence and prolong OS.Several studies have shown certain efficacy of these treatments.However,the specific efficacy and safety of combined NAT and AT in ICC treatment require further validation.This study was conducted to evaluate the value of combining NAT and AT in improving the therapeutic outcomes of ICC patients through a multicenter retrospective analysis,so as to provide scientific evidence for optimizing treatment strategies.Methods:The clinicopathologic data of 576 patients with ICC who underwent radical resection and were pathologically confirmed from 13 hospitals in China between December 2011 and December 2017 were retrospectively collected.Patients were grouped based on their treatment modality:NAT+AT group,AT group,and non-NAT/AT group.The three patient groups were matched pairwise in a 1∶1 ratio using propensity score matching(PSM)to balance baseline data.The Kaplan-Meier method was used to analyze OS and disease-free survival(DFS),and subgroup analyses were conducted according to the 8th edition of the AJCC TNM staging system.Results:A total of 395 ICC patients were included in the final analysis,with 42 patients(10.6%)in the NAT+AT group,62 patients(15.7%)in the AT group,and 291 patients(73.7%)in the non-NAT/AT group.Before PSM,significant differences were observed between groups in terms of CA19-9,liver function Child-Pugh classification,intraoperative blood loss,surgical margin,differentiation grade,vascular invasion,ECOG score,and lymph node dissection ratio(all P<0.05).After PSM,there were no significant differences in baseline characteristics between the groups(all P>0.05).After matching,the median OS and DFS in the NAT+AT group were significantly better than in the AT and non-NAT/AT groups(both P<0.05),while there were no significant differences in OS and DFS between the AT and non-NAT/AT groups(both P>0.05).Subgroup analysis showed that in TNM stage I patients,DFS in the NAT+AT group was significantly better than in the non-NAT/AT group(P<0.05),but OS was not significantly different(P>0.05).In TNM stage Ⅱ and Ⅲ patients,both OS and DFS in the NAT+AT and AT groups were significantly better than in the non-NAT/AT group(both P<0.05),and DFS in the NAT+AT group was significantly better than in the AT group in TNM stage Ⅲ patients(P<0.05).Conclusion:NAT combined with AT provides better survival benefits for patients with locally advanced ICC,but its benefit for early-stage ICC patients is limited.However,the retrospective design and sample size limitations of this study may affect the stability of the results,and future large-sample,multicenter,prospective studies are needed for further validation.

Objective To understand the molecular epidemiological characteristics and hypervirulence evolution trend of ST11 carbapenem-resistant Klebsiella pneumoniae(CRKP)isolated from medical institutions in Shanghai,and provide scientific basis for formulating the prevention and control measures of drug-resistant organisms.Methods A total of 201 strains of CRKP isolated from 12 medical institutions in Shanghai from 2021 to 2022 were collected.Antimicrobial susceptibility testing and whole genome sequencing were performed.The concatenated data was used for multilocus sequencing typing(MLST),serum typing(wzi typing),as well as analysis of resistance and viru-lence genes.Results All 201 CRKP strains were multidrug-resistant organisms(MDROs).These strains were al-most completely resistant to carbapenems,cephalosporins,and quinolones.Drug resistance gene analysis showed that 93.03％of CRKP strains carried KPC gene.201 CRKP strains were divided into 6 ST types and 10 capsule wzi types,with ST11-KL64(n=104)being the dominant type,followed by ST15-KL19(n=54).52.24％(n=105)of CRKP carried rpmA/rpmA2+iucA+iutA+iroN genes.Conclusion CRKP isolated from medical institutions in Shanghai is mainly ST11-KL64 type with severe multidrug resistance,and more than half of the strains are hyper-virulent carbapenem-resistant Klebsiella pneumoniae(hv-CRKP).It is necessary to continuously strengthen the monitoring of the molecular characteristics of CRKP,so as to prevent outbreaks of healthcare-associated infection.

OBJECTIVE To investigate the clinical efficacy of integrating pharmacists into family health teams （FHTs） for long-term medication therapeutical management （MTM） in stroke patients， and empirically evaluate the service model. METHODS A pharmacist team， jointly established by clinical and community pharmacists from the Affiliated Suzhou Hospital of Nanjing Medical University （hereinafter referred to as “our hospital”）， developed a pharmacist-supported MTM model integrated into FHTs. Using a prospective randomized controlled design， 170 stroke patients discharged from our hospital （July 2022-December 2023） and enrolled in FHTs at Suzhou Runda Community Hospital were randomly divided into trial group （88 cases） and control group （82 cases） according to random number table. The control group received routine FHTs care （without pharmacist involvement in the team collaboration）， while the trial group xhz8405@126.com received 12-month MTM services supported by pharmacists via an information platform. These services specifically included innovative interventions such as personalized medication regimen optimization based on the MTM framework， dynamic medication adherence management， medication safety monitoring， a home medication assessment system， and distinctive service offerings. Outcomes of the 2 grousp were compared before and after intervention， involving medication adherence （adherence rate， adherence score）， compliance rates for stroke recurrence risk factors [blood pressure， low-density lipoprotein cholesterol （LDL-C）]， and incidence of adverse drug reactions （ADR）. RESULTS After 12 months， the trial group exhibited significantly higher medication adherence rates， improved adherence scores， higher compliance rates for blood pressure and LDL-C targets compared to the control group （P＜0.05）. The incidence of ADR in the trial group （4.55%） was significantly lower than that in the control group （8.11%）， though the difference was not statistically significant （P＞ 0.05）. CONCLUSIONS Pharmacist involvement in FHTs to deliver MTM services significantly enhances medication adherence and optimizes risk factor for stroke recurrence， offering practical evidence for advancing pharmaceutical care in chronic disease management under the family doctor system.

Objective:To analyze the clinical characteristics and prognosis of primary autoimmune cerebellar ataxia (PACA) patients with autoantibodies.Methods:Patients from the Department of Neurology, Peking Union Medical College Hospital (from March 2013 to December 2023) who met the modified diagnostic criteria of PACA were collected. Cell based assay and tissue based assay were used to detect anti-cerebellar antibodies. The clinical features, results of neuroimaging, cerebrospinal fluid examinations and the prognosis of the patients were analyzed. Modified Rankin Scale (mRS) score≤2 at the last follow-up was defined as a favorable prognosis. Exacerbation of cerebellar ataxia after clinical improvement or stabilization for at least 2 months was defined as relapse.Results:A total of 20 patients were included, including 7 males. The onset age was 48.4 (22.8, 59.3) years. Gait ataxia was the most common cerebellar symptom. Extracerebellar neurological abnormalities included pyramidal sign, peripheral neuropathy/radiculopathy and diplopia. Elevated cerebrospinal fluid white blood cells and positive specific oligoclonal bands were observed in 4/16 and 7/15 of patients, respectively. The brain magnetic resonance imaging examination of the patients showed that 8 patients had no obvious abnormalities, 9 patients showed cerebellar atrophy, and 3 patients showed abnormal signals in the brain or cerebellum. A total of 9 different anti-cerebellar antibodies were detected in the patient′s serum and (or) cerebrospinal fluid, with the most common being anti-Homer-3 antibodies ( n=7). After immunotherapy, 13/17 of patients improved. After 37.5 (21.0, 93.0) months of follow-up, the median mRS score of the patients was 3, and 8 patients (8/20) achieved good prognosis and 6 patients experienced disease recurrence. Conclusions:The clinical manifestations of PACA patients have certain heterogeneity, and positive anti-neuroantibodies and meeting PACA diagnostic criteria are the main basis for diagnosing the disease. Immunotherapy is effective for most patients, but there is still a considerable proportion of patients who have not achieved a good long-term functional prognosis.

Objective:To explore the relationship between the dynamic alterations of immune cell subsets in a patient with autoimmune encephalitis and the clinical relapses.Methods:For a patient with multiple relapses of anti-N-methyl-D-aspartate receptor encephalitis superimposed with myelin oligodendrocyte glycoprotein antibody-associated disease who visited Peking Union Medical College Hospital on July 18, 2018, the lymphocyte subsets were monitored dynamically over a long period and the relationship between lymphocyte subsets and the relapses was summarized.Results:The 38-year old male patient experienced a total of 5 episodes (including 4 relapses) during the six-year immunotherapy and follow-up process, and responded well to first-line and maintenance immunotherapy. His relapses occurred during drug reduction. Finally, the neurological symptoms resolved after rituximab treatment. A total of 39 tests of peripheral blood lymphocyte subsets were conducted during the follow-up, and 5 peaks of elevated CD19 positive B cells, 9 peaks of elevated CD3 positive T cells and 11 peaks of elevated natural killer cells were observed. The peak period of peripheral blood CD19 positive B cells exactly coincided with clinical relapses. While the consistency rates of clinical relapse and the peaks of peripheral blood CD3 positive T cells and natural killer cells were 5/9 and 2/11, respectively.Conclusions:The dynamic alterations of CD19 positive B cells in peripheral blood are correlated with the clinical relapse of autoimmune encephalitis and can predict clinical relapse.
