As the core vehicle for preserving and transmitting traditional Chinese medicine（TCM） academic thought and clinical experience， the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine， this study conducted a comprehensive analysis of critical challenges， including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic， encompassing three dimensions of authenticity and standardization， characteristics and advantages， application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment， while aligning with modern scientific research standards， achieving a balance between individualized TCM experience and standardized evaluation. Concurrently， this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases， contributing significantly to the inheritance of TCM knowledge， evidence-based practice， and the reform of talent evaluation mechanisms.

Objective:To retrospectively analyze and compare the clinical effects of rigid neuroendoscopic hematoma removal and drilling irrigation drainage in the treatment of chronic subdural hematomas with mixed density on head CT, and explore the appropriate surgical methods for chronic subdural hematomas with mixed density.Methods:A retrospective case-control study was conducted to analyze the clinical data of 80 patients with CSDH with mixed density CT findings admitted to the Department of Neurosurgery of Guizhou Medical University Affiliated Hospital from January 2021 to November 2023. There were 57 males and 23 females. According to the surgical method, patients were divided into endoscopic group ( n=36) and drilling group ( n=44). Patients in the endoscopic group underwent hard neuroendoscopic hematoma removal surgery, while patients in the drilling group underwent drilling flushing and drainage surgery. Compared the surgical time, drainage time, hematoma clearance rate, length of hospital stay, markwalder neurological function grading, and activities of daily living (ADL) score between two groups 30 days after surgery. Followed up for 3 months to record the recurrence situation.Measurement data with a normal distribution were expressed as mean±standard deviation ( ± s), and t-test was used for inter-group comparison. Measurement data with a non-normal distribution were expressed as M( Q1, Q3), and rank sum test was used for inter-group comparison. Chi-square test or Fisher′s exact test was used for inter-group comparison of count data. Rank sum test was used for inter-group comparison of ordinal data. Results:The operation time, postoperative drainage time, 24-hour hematoma clearance rate, midline deviation distance and hospital stay in the endoscopic group respectively were (77.50±8.15) min, 1.00(1.00, 2, 00) d, (95.00±2.66)%, 1.00(0.00, 2.00) mm, (9.47±2.52) d. The drilling group were (44.77±6.56) min, 3.00(2.25, 3.00) d, (87.86±3.43)%, 3.00(2.00, 3.00) mm, (11.84±3.28) d, the difference was statistically significant between the two groups ( P<0.05). Comparison of long-term efficacy in the endoscopic group, the hematoma clearance rate at 30 days after operation, the ADL score at 30 days after operation, and the number of recurrence cases at 3 months after operation respectively were 99.00(97.25, 100.00)%, (88.06±7.86) points, and 1 case. The drilling group were 93.50(91.25, 95.75)%, (83.29±9.58) points and 10 cases, with statistical difference between the two groups( P<0.05). 30 day postoperative Markwalder neurological functional grading, there were 27 cases grades 0, 9 cases of grade I, and 0 cases of grade II in endoscopic surgery. In the drilling group, there were 24 cases, 15 cases, and 5 cases, respectively. The difference between the two groups was statistically significant ( P<0.05). Conclusions:Compared with drilling and drainage irrigation surgery, neuroendoscopic treatment of mixed density chronic subdural hematoma takes a relatively long time, but the hematoma clearance rate is higher, the hospitalization time is shorter, the postoperative recovery is faster and the recurrence rate is lower. Neuroendoscopic therapy has unique advantages and may be more suitable for the treatment of mixed density CSDH.

Objective:To analyze the molecular evolutional characteristics of the hemagglutinin and neuraminidase genes of influenza A (H3N2) viruses isolated in Yancheng from 2022 to 2024.Methods:The throat swab specimens of influenza-like illness ( ILI) from sentinel surveillance hospital and outbreak sites were detected using the method of real time Rt-qPCR. The influenza A(H3N2) viruses were isolated using MDCK cells culture method from April 2022 to Marh 2024. The strains isolated from 2022 to 2024 were selected randomly and their sequences of the HA1 and NA genes were amplified through one step RT-PCR method and the PCR products were sequenced.The nucleotide and amino acid site variations and evolutionary characteristics of the genes were analyzed using relevant bioinformatics software. The mutations of genes and nucleic acid locus were analyzed and the evolutional trees were generated using bioinformatics software.Results:A total of 5 020 samples were collected between April 2022 and March 2024, the positive detection rate of influenza virus nucleic acid was 18.59%(933/5 020).The winter and spring influenza peaks were obvious in the two monitoring seasons from April 2022 to March 2024. Among them, the summer influenza peak was obvious in the monitoring season from April 2022 to March 2023, and the H3N2 subtype influenza virus was the dominant epidemic strain in the two monitoring seasons. Genetic evolution tree displayed: the clustering relationships of the respective branches of HA1 and NA genes of 32 strains isolated in Yancheng were basically the same.The HA1 and NA genes of 24 strains isolated from 2023-2024 in Yancheng and the 2022-2024 Northern Hemisphere vaccine strain A/Darwin/9/2021 (H3N2) were located in the 3C.2a1b2a.2a.3a.1 evolutionary lineage, while the 8 strains isolated in the 2022 in Yancheng and the 2021-2022 Northern Hemisphere vaccine strain A/Cambodia/e0826360/2020 (H3N2) were located in the 3C.2a1b.2a.1a evolutionary lineage.The 6 strains (A/JSTH/11735/2023, A/JSTH/11788/2023, A/JSTH/11974/2023, A/JSYD/353/2023, A/JSYD/354/2023, A/JSTH/138/2023) all exhibited variations in the F79L, N122D, P239S, and K276E amino acid sites, which were present in both sporadic and outbreak strains. Because the strains of the antigen epitopes, receptor binding sites and glycosylation sites in the HA1 genes had a certain degree of variations in Yancheng in the 2022-2024 year, the immunogenicity matching between the 24 strains isolated in the 2023-2024 and the Northern Hemisphere vaccine strain A/Darwin/9/2021 was good, while the immunogenicity matching between the 8 strains isolated in the 2022 and the Northern Hemisphere vaccine strain A/Cambodia/e0826360/2022 was good; 32 strains isolated from 2022 to 2024 had no mutations in catalytic residues and drug resistant sites of NA genes.Conclusion:These result indicated that the HA1 and NA genes of influenza A/H3N2 viruses circulated in Yancheng city from 2022 to 2024 are changed gradually.The accumulation of these mutations would result in antigenic drift of influenza A(H3N2) viruses and increase the mismatching of the recommended vaccine strain.Compared with the vaccine strain A/Darwin/9/2021(H3N2), the strains isolated in the 2022 had substantially result in antigenic drift on the whole.The influenza A(H3N2) viruses surveillance should be strengthened to find the new mutant of virus in time.

Objective:To accurately ascertain the whole genome sequencing and the composition of open reading frames (ORFs) of non-replicating Tiantan strain of vaccinia virus (NTV) using next-generation long-read sequencing technology.Methods:NTV, obtained from our laboratory stock, was amplified and purified on chicken embryo fibroblast cells(CEFs), and the full-length genomic nucleic acid of NTV was extracted. The PacBio HiFi sequencing platform was utilized for de novo assembly to obtain the complete genomic sequence of NTV. Using a homology annotation strategy, we identified its ORF composition and compared it with known non-replicating vaccinia virus strains. Results:The total length of NTV′s genome was 171 729 bp, with a GC content of 33%. Its unique inverted terminal repeat (ITR) region comprised hairpin structures, two tandem repeat regions, and three non-repeat regions. NTV contained 166 ORFs, with major differences observed in the ITR and its surrounding regions when compared to MVA-BN and NYVAC. These three strains shared a common set of 138 ORFs. NTV encoded six unique ORFs related to virus evasion of host antiviral response.Conclusions:This study accurately determines the whole genome sequencing and ORFs composition of NTV, and reveals its similarities and differences with other replication-deficient vaccinia virus strains, which pave a way for the development and application of the next generation of monkeypox vaccines and novel viral vectors.

Objective:To innovatively applicate and evaluate the efficacy of simultaneous off-pump coronary artery bypass grafting (OPCABG), modified pulmonary vein isolation and left atrial ablation treating coronary heart disease combined with atrial fibrillation.Methods:From January 2021 to August 2023, a retrospective analysis was conducted on the clinical data of 76 patients who underwent OPCABG, modified pulmonary vein isolation and left atrial ablation in our department. There were 57 males and 19 females, aged(63.42 ± 8.25)years, with a median duration of 26 months of atrial fibrillation. Follow up was conducted for 1 year after surgery, and 24-hour dynamic electrocardiogram was rechecked to observe the recurrence of atrial fibrillation.Results:All patients successfully completed the surgery without any conversion to extracorporeal circulation, and no perioperative death. On the first day after surgery, there was a conversion to sinus or junctional rhythm in 69(90.79%) cases. The median postoperative hospitalization time was 7 days, with no postoperative cerebral infarction or complications of thoracotomy hemostasis. All patients recovered and were discharged, with a sinus rhythm maintained at 67(88.16%) upon discharge. Compared with preoperation, there were 56 (73.68%) patients with sinus rhythm after 1 year of postoperative follow-up( P<0.05). Conclusion:The simultaneous OPCABG, modified pulmonary vein isolation and left atrial ablation treating coronary heart disease with atrial fibrillation was safe, feasible, and effective. The mid- and long-term efficacy needs to be further confirmed through multicenter and large-scale studies.

Objectives:To discuss the inhibitory effect of Lactobacillus reuteri on the replication of rotavirus(RV)strain SA11 in vivo and in vitro,and to clarify its effect on the expression of related immune factors.Methods:For in vitro experiments,Lactobacillus reuteri was cultured and identified,and the standard curve and growth curve were plotted to screen the optimal time and concentration for Lactobacillus reuteri cultivation.The cells were infected with Lactobacillus reuteri at the concentrations of 5×108,10×108,50×108,100×108,200×108,and 500×108 CFU·mL-1,and the surival rates of Caco-2 cells were detected by trypan blue staining method.Various concentrations of Lactobacillus reuteri were co-incubated with RV in vitro and applied to the Caco-2 cells.The cells were divided into negative control group(NC group),positive control group(PC group),and 107,108,109,and 1010 CFU·mL-1 Lactobacillus reuteri groups.Immunofluorescence focus method was used to detect the viral titers in the Caco-2 cells after treated with Lactobacillus reuteri and real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the copy numbers of RV VP6 gene in the Caco-2 cells after treated with various concentrations of Lactobacillus reuteri.In in vivo experiments,25 litters of SPF suckling mice were divided into control group,RV group(infected with SA11 strain),Ab-NC group(treated with antibiotic to deplete gut microbiota),Ab-RV group(depleting gut microbiota and then infected with SA11 strain),and Ab-Lac-RV group(depleting gut microbiota,treated with Lactobacillus reuteri,and then infected with SA11 strain).The fecal samples were collected on days 2,4,6,8,and 10 gavage,colon tissue sample were collected on day 4 of and RT-qPCR method was used to detect the copy numbers of RV VP6 gene in feces and the mRNA expression levels of interleukin(IL)-1β,IL-8,IL-10,interferon-γ(IFN-γ),and tumor necrosis factor-α(TNF-α)in colon tissue of the suckling mice in vartious groups.Results:The Lactobacillus reuteri grew well,with round,smooth,and milky white convex colonies and neat edges.After Gram staining,the bacteria appeared purple,irregular,and square-shaped rods.16SrDNA sequencing showed 99%sequence homology,indicating successful activation of Lactobacillus reuteri.The number of live Lactobacillus reuteri was linearly related to the absorbance(A)value,and the standard curve for regression analysis was Y=0.437 5X+0.000 6,R2=0.999 4.During the 0-2 h cultivation period,the bacteria were at the logarithmic growth phase with slow growth;from 2-14 h,the bacteria grew rapidly and stabilized at 14-16 h,reaching the growth rate peak at 16 h,after which they entered the decline phase.Infection with Lactobacillus reuteri at concentrations of 5×108,10×108,50×108,100×108,and 200×108 CFU·mL-1 resulted in the survival rates of Caco-2 cells were all>90%,so these concentrations were selected for the further experiments.Compared with PC group,the copy numbers of RV VP6 gene in the Caco-2 cells in 5×108,10×108,50×108,100×108,and 200×108 CFU·mL-1 Lactobacillus reuteri groups were significantly decreased(P<0.01).Compared with PC group,the viral titers in the Caco-2 cells in 107,108,109,and 1010 CFU·mL-1 Lactobacillus reuteri groups were significantly decreased(P<0.01).Compared with control group,the numbers of gut microbiota colonies in Ab-NC,Ab-RV,and Ab-Lac-RV groups were significantly decreased,indicating successful depletion of gut microbiota in the suckling mice.On days 2 and 4 after gavage,the RV VP6 gene copy number in the feces in Ab-RV group was significantly lower than that in RV group(P<0.05).On days 4,6,8,and 10 after gavage,the RV VP6 gene copy number in the feces in Ab-Lac-RV group was significantly lower than that in Ab-RV group(P<0.05).Compared with control group,the expression levels of IL-1β,IL-10,IFN-γ,and TNF-α mRNA in colon tissue in Ab-RV and Ab-Lac-RV groups were significantly increased(P<0.05 or P<0.01),while the expression level of IL-8 mRNA was significantly decreased(P<0.05),and the expression level of IL-10 mRNA in colon tissue in Ab-LAC-RV group was significantly increased(P<0.01).Conclusion:Lactobacillus reuteri may inhibit the RV replication by upregulating the expressions of IL-1β,IL-10,IFN-γ,and TNF-α mRNA and downregulating the expression of IL-8 mRNA.

BACKGROUND: The purpose of this study was to investigate the specific effects of signal transducer and activator of transcription 4 (STAT4)-induced long intergenic nonprotein coding RNA 1278 (LINC01278) on the growth of non-small cell lung cancer (NSCLC) cells involved in the microRNA (miR)-877-5p/activated transcription factor 4 (ATF4) axis. METHODS: NSCLC tumor tissue and adjacent normal tissue were collected. Human normal lung epithelial cell BEAS-2B and human NSCLC cell lines (H1299, H1975, A549, H2228) were collected. The expression levels of STAT4, LINC01278, miR-877-5p, and ATF4 were detected. A549 cells were screened for subsequent experiments. The proliferation ability of cells was detected by colony formation experiment. Cell apoptosis was tested by flow cytometry. Scratch test and transwell assay were used to detect the migration and invasion ability of cells. Biological function of LINC01278 in NSCLC was confirmed by xenograft experiments. RESULTS: Low expression miR-877-5p and high expression of STAT4, LINC01278 and ATF4 were detected in NSCLC.Silenced LINC01278 in A549 cell depressed cell proliferation, migration and invasion, but facilitated cell apoptosis.LINC01278 was positively correlated with STAT4 and could directly bind to miR-877-5p. Upregulating miR-877-5p suppressed NSCLC cell progression, while downregulating miR-877-5p had the opposite effect. Upregulating miR-877-5p abrogated the effects of silenced LINC01278 on NSCLC cell progression. MiR-877-5p targeted ATF4. ATF4 upregulation could partly restore the carcinogenic effect of LINC01278 in vitro and in vivo. CONCLUSION Our data supports that STAT4-induced upregulation of LINC01278 promotes NSCLC progression by modulating the miR-877-5p/ATF4 axis, suggesting a novel direction for NSCLC treatment.
