Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

OBJECTIVE: Poxviruses are zoonotic pathogens that infect humans, mammals, vertebrates, and arthropods. However, the specific role of ticks in transmission and evolution of these viruses remains unclear. METHODS: Transcriptomic and metatranscriptomic raw data from 329 sampling pools of seven tick species across five continents were mined to assess the diversity and abundance of poxviruses. Chordopoxviral sequences were assembled and subjected to phylogenetic analysis to trace the origins of the unblasted fragments within these sequences. RESULTS: Fifty-eight poxvirus species, representing two subfamilies and 20 genera, were identified, with 212 poxviral sequences assembled. A substantial proportion of AT-rich fragments were detected in the assembled poxviral genomes. These genomic sequences contained fragments originating from rodents, archaea, and arthropods. CONCLUSION Our findings indicate that ticks play a significant role in the transmission and evolution of poxviruses. These viruses demonstrate the capacity to modulate virulence and adaptability through horizontal gene transfer, gene recombination, and gene mutations, thereby promoting co-existence and co-evolution with their hosts. This study advances understanding of the ecological dynamics of poxvirus transmission and evolution and highlights the potential role of ticks as vectors and vessels in these processes.

Objective To analyze the risk factors for postoperative intra-abdominal infection in gastric cancer pa-tients,as well as construct and validate a nomogram prediction model.Methods 588 gastric cancer surgery pa-tients who admitted to the Department of General Surgery of the First Affiliated Hospital of Soochow University from April 2021 to March 2024 were selected as the study subjects.Clinical data of patients were collected and ran-domly divided into the training set and the validation set according to the ratio of 3∶1.Clinical data between two groups of patients were compared.Patients were divided into the infection group and non-infection group according to whether they had intra-abdominal infection after surgery.Univariate and multivariate analyses were conducted,and a nomogram prediction model was constructed and validated based on the results of multivariate analysis.Results Among the 588 patients,52(8.84％)had postoperative intra-abdominal infection.A total of 65 strains of patho-gens were detected from 52 peritoneal fluid specimens,out of which 47(72.31％)were Gram-negative bacteria,15(23.07％)were Gram-positive bacteria,and 3(4.62％)were fungi.Multivariate logistic regression analysis showed that the degree of eradication(microscopic residue),combined organ resection,hypertension,history of ab-dominal surgery,and duration of surgery were all independent risk factors for postoperative intra-abdominal infec-tion in gastric cancer patients(all P＜0.05).Based on multivariate analysis results,a nomogram prediction model for postoperative intra-abdominal infection in gastric cancer patients was constructed.The receiver operating charac-teristic(ROC)curve result showed that the areas under the ROC curve(AUCs)of the training set and validation set were 0.764(95％CI:0.677-0.852)and 0.712(95％CI:0.565-0.860,respectively,indicating that the model had good discriminability for postoperative intra-abdominal infection in gastric cancer patients.Hosmer-Lemeshow test showed a x2 value of 8.491 and a P value of 0.387,suggesting goodness fit of the model.The decision curve analysis(DCA)result showed that within the risk threshold ranges of the training set(0.05-0.4)and validation set(0.1-1.0,positive benefits may be obtained by using the model to intervene in patients with high risk of post-operative intra-abdominal infection.Clinical impact curve(CIC)analysis result showed that within the risk thresh-old ranges of the training set(0-0.4)and validation set(0-0.5),the number of infected cases predicted by the model was higher than the actual number,indicating good clinical practicality of the model.Conclusion Construc-tion of a nomogram prediction model based on independent risk factors for postoperative intra-abdominal infection in gastric cancer can provide a quantitative and intuitive reference for the early clinical assessment of postoperative in-tra-abdominal infection in gastric cancer.

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

hippocampus and HT22 cells of hypoxia pre-acclimated(HPC)mice and their relationship with neuroprotection.Methods(1)Thirty-six male Institute of Cancer Research(ICR)mice were randomly divided into three groups according to the random number table method of complete randomization:the control group,the hypoxia group and the hypoxia preconditioning group,with 12mice in each group.Mice in the control group were not exposed to hypoxia,mice in the hypoxia group were exposed to hypoxia once,and mice in the hypoxia preconditioning group were exposed to hypoxia four times.Immediately after the end of hypoxia treatment,all mice were decapitated and killed and hippocampal tissues were isolated and preserved in groups.(2)HT22 cells were cultured in medium containing 10％foetal bovine serum and 100 U/ml penicillin-streptomycin.When cell confluence was greater than 90％,they were transferred to 24-well plates for culture and then processed in 2 batches.6 pmol disordered small interfering RNA(siRNA),MALAT1 siRNA(siMALAT1),NEAT1 siRNA(siNEAT1),siMALAT1+siNEAT1 were transfected into the negative control group,siMALAT1 group,siNEAT1 group,and siMALAT1+siNEAT1 group of the first batch of HT22 cells one by one by transfection reagent,and the blank group did not have any treatment;then they were cultured under normal conditions(5％CO2 and 95％air)for 48 h.In the second batch of HT22 cells,6 pmol of disordered siRNA,disordered siRNA,siMALAT1,siMALAT1,siNEAT1 and siNEAT1 were transfected one by one correspondingly to the negative control group and the negative control+oxygen-glucose deprived/reoxygen(OGD/R)group,siMALAT1 group,siMALAT1+OGD/R,siNEAT1 group,siNEAT1+OGD/R group.48 h after transfection,HT22 cells of negative control group,siMALAT1 group and

mRNA and NR2B protein after transfection of HT22 cells in each group,and the relative expression levels of haemoglobin breakdown products and activated cysteine protease protein 3 after transfection and OGD/R of HT22 cells in each group.The survival rate of HT22 cells in each group was calculated.Results(1)The differences in relative expression of MALAT1(F=43.92),NEAT1(F=506.4),NR2B mRNA(F=50.64)and NR2B protein(F=41.24)in the hippocampus of mice in the three groups were statistically significant(all P＜0.05).The relative expression of MALAT1([1.68±0.06]vs.[1.00±0.08]),NR2B mRNA([1.26±0.06]vs.[1.00±0.01]),and NR2B protein([1.47±0.05]vs.[1.00±0.01])was increased in the hypoxia group as compared to the control group(all P＜0.05),whereas the relative expression of NEAT1([1.02±0.10]vs.[1.00±0.03])were not statistically significant(P＞0.05),and the relative expression of MALAT1([1.12±0.13]vs.[1.00±0.08])and NEAT1([2.88±0.10]vs.[1.00±0.03])were increased in hypoxic preconditioned group.Compared with hypoxia group,the relative expression of NR2B mRNA([0.54±0.07]vs.[1.26±0.06])and NR2B protein([1.17±0.07]vs.[1.47±0.05])were decreased(both P＜0.05).(2)The differences in the relative expression of NR2B mRNA(F=36.92)and NR2B protein(F=56.98)after transfection of HT22 cells in the five groups were statistically significant(both P＜0.05).Compared with the negative control group,siMALAT1 group(NR2B mRNA:[2.04±0.08]vs.[0.94±0.04],NR2B protein:[1.72±0.13]vs.[0.93±0.02]),siNEAT1 group(NR2B mRNA:[2.15±0.13]vs.[0.94±0.04],NR2B protein:[1.87±0.46]vs.[0.93±0.02]),siMALAT1+siNEAT1 group(NR2BmRNA:[2.09±0.16]vs.[0.94±0.04],NR2B protein:[2.07±0.30]vs.[0.93±0.02])showed the relative NR2B mRNA and NR2B protein expression were increased(all P＜0.05).(3)Differences in relative expression of haematopoietin breakdown product(145/150 kDa)protein(F=12.43),haematopoietin breakdown product(120 kDa)protein(F=7.15),and activated cysteamine protease protein 3 protein(F=6.61)were statistically significant in the 6 groups of HT22 cells transfected and treated with OGD/R(all P＜0.05).Compared with the siMALAT1 group,the siMALAT1+OGD/R group had 145/150kDa([1.42±0.48]vs.[0.85±0.34]),120 kDa([1.33±0.37]vs.[0.52±0.19])haematopoietin catabolism products and activated cysteamine protease protein 3([2.43±0.35]vs.[1.15±0.24])relative expression increased(all P＜0.05);compared with the negative control+OGD/R group,the siMALAT1+OGD/R group showed an increase in 145/150kDa([1.42±0.48]vs.[1.23±0.17]),120 kDa([1.33±0.37]vs.[0.80±0.21])relative expression of haematopoietin breakdown products and activated cysteamine protease protein 3([2.43±0.35]vs.[1.46±0.39])increased(all P＜0.05);compared with the siNEAT1 group,the siNEAT1+OGD/R group had a higher expression of 145/150 kDa([1.28±0.44]vs.[0.87±0.32]),120 kDa([0.81±0.36]vs.[0.63±0.16])relative expression of haematopoietic proteolytic products and activated cysteamine protease protein 3([1.51±0.45]vs.[1.01±0.27])increased(all P＜0.05).(4)The difference in HT22 cell survival rate among the 6 groups was statistically significant(F=5.54,P＜0.05).Compared with the negative control group,HT22 cell survival was decreased in the siMALAT1,siNEAT1,siMALAT1+OGD/R and siNEAT1+OGD/R groups([0.65±0.40],[0.76±0.35],[0.24±0.17],[0.23±0.16]vs.[0.84±0.04],all P＜0.05);cell viability was reduced in the siMALAT1+OGD/R group compared with the siMALAT1 group([0.24±0.17]vs.[0.65±0.40],P＜0.05);and cell viability was reduced in the siNEAT1+OGD/R group compared with the siNEAT1 group([0.23±0.16]vs.[0.76±0.35],P＜0.05).Conclusion HPC increased the expression of MALAT1 and NEAT1 in the hippocampus of mice,and MALAT1 and NEAT1 may participate in the neuroprotective effect of mice after ischemia and hypoxia by affecting the expression of NR2B.

Objective To explore the clinical efficacy and influencing factors of omadacycline(OMC)in the treat-ment of patients with infectious diseases.Methods Data about hospitalized patients who received OMC monothera-py or combination therapy at Xiangya Hospital of Central South University from January 2022 to December 2023 were analyzed retrospectively.The influencing factors for failure of OMC treatment was analyzed by univariate and multivariate logistic regression analysis.Results A total of 160 patients were included in analysis,with an overall effective treatment rate of 69.4％(n=111).After treatment with OMC,patients in effective group was observed that body temperature improved([36.83±0.52]℃ vs[37.85±0.92]℃,P＜0.001),white blood cell count([7.78±4.07]× 109/L vs[10.06±6.49]× 109/L,P＜0.001),procalcitonin([0.63±1.19]ng/mL vs[4.43±10.14]ng/mL,P=0.001),C-reactive protein([35.16±37.82]mg/L vs[105.08±99.47]mg/L,P＜0.001),and aspartate aminotransferase([50.50±40.04]U/L vs[77.17±91.43]U/L,P=0.004)all decreased signifi-cantly.Only one patient had adverse reactions such as diarrhea,but treatment was not interrupted.Univariate ana-lysis showed that patients in failure treatment group had a higher acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score(17.0[9.5-22.0]vs 12.0[9.0-19.0],P=0.046)and sequential organ failure assessment(SOFA)score(7.0[4.5-10.0]vs 4.0[2.0-9.0],P=0.019).Multivariate analysis showed that end-stage liver disease(OR=77.691,95％CI:5.448-1 107.880,P=0.001),mechanical ventilation(OR=6.686,95％CI:1.628-27.452,P=0.008)and the combination treatment of vancomycin(OR=6.432,95％CI:1.891-21.874,P=0.003)were risk factors for the failure of OMC treatment,while the course of OMC treatment(OR=0.905,95％CI:0.825-0.994,P=0.037)was a protective factor for the effective treatment.Conclusion OMC can be used as an alternative therapy for refractory severe infection,with fewer adverse reaction.End-stage liver disease,mechanical ventilation and combination treatment of vancomycin are risk factors for failure of OMC treatment in in-fected patients.Adequate OMC treatment course can improve patients'clinical outcome,large-scale case studies are needed to confirm the initial conclusion.

OBJECTIVE To establish the fingerprint of the ethanol extract from Callicarpa nudiflora， analyze its anti- respiratory syncytial virus （RSV） activity in vitro， and study the relationship between spectrum and effect. METHODS Using 10%， 30%， 50%， 70% and 90% ethanol as solvent， 20 batches of ethanol extracts from 4 batches of C. nudiflora were prepared. The fingerprints for 20 batches of ethanol extracts from C. nudiflora were mapped by ultra-high-performance liquid chromatography （UPLC）， and the similarity evaluation was conducted by using the Similarity Evaluation System for Traditional Chinese Medicine Chromatographic Fingerprints （2012 edition）. The cytopathic effect method and MTT method were used to investigate the in vitro inhibitory activity of the ethanol extracts from C. nudiflora on RSV. Pearson correlation analysis， grey correlation degree and orthogonal partial least squares （OPLS） analysis were used to study the spectrum-effect relationship. RESULTS There were 25 common peaks in 20 batches of ethanol extracts from C. nudiflora， and the similarities ranged from 0.912 to 0.998， and the RSDs of common peak areas were 33.54%-162.28%. The average values of IC50 for RSV of 20 batches of ethanol extracts from C. nudiflora were 9.55-272.23 μg/mL. The results of Pearson correlation analysis， grey correlation analysis and OPLS analysis showed that the Pearson correlation coefficients （P＜0.05） of the common peaks 8， 10， 12， 16， 18-19， 22-24 with pharmacodynamic indicators and regression coefficients were all negative， the correlation coefficients were all greater than 0.6， and the values of variable importance in projection were all greater than 1. CONCLUSIONS Twenty batches of ethanol extracts from C. nudiflora have similar components but significant differences in content， and exhibit different degrees of anti-RSV activity in vitro. The corresponding components of common peaks 8， 10， 12， 16， 18-19， 22-24 may be the characteristic components of anti-RSV of C. nudiflora.

OBJECTIVE: To evaluate the prospective association between cumulative resting heart rate (cumRHR) and rapid renal function decline (RRFD) in a cohort of individuals aged 60 and older. METHODS: In the Tianjin Chronic Kidney Disease Cohort Study, the individuals who underwent three consecutive physical examinations between 2014 and 2017, with estimated glomerular filtration rate (eGFR) greater than 60 mL/min per 1.73 m² and aged 60 years or older were enrolled. A total of 27,564 patients were prospectively followed up from January 1, 2017 to December 31, 2020. The 3-year cumRHR was calculated. The primary outcome was RRFD, defined as an annualized decline in eGFR of 5 mL/min per 1.73 m² or greater. Logistic and restricted spline regression models and subgroup analysis were used to investigate the association of cumRHR with RRFD after adjusting for all confounders. RESULTS: During a median follow-up of 3.2 years, a total of 4,347 (15.77%) subjects developed RRFD. In fully-adjusted models, compared with the lowest quartile of cumRHR, the odds ratio (OR) for the highest was 1.44 (1.28-1.61), P < 0.001. Furthermore, each 1-standard deviation (27.97 beats/min per year) increment in cumRHR was associated with a 17% (P < 0.001) increased risk of RRFD, with a linear positive correlation (P for non-linear = 0.803). Participants with a 3-year cumRHR ≥ 207 (beats/min) * year (equivalent to ≥ 69 beats/min per year in 3 years) were found to be at a higher risk of RRFD. CONCLUSIONS The cumRHR is significantly associated with a higher risk of RRFD among older adults. These results might provide an effective goal for managing and delaying the decline of renal function in the older adults.

Objective:To explore the role of arthroscopic exploration in the treatment of tibial plateau fractures with homeopathic double reverse traction reduction and internal fixation.Methods:A retrospective analysis was conducted on the data of 188 patients with tibial plateau fractures treated by homeopathic double reverse traction reduction assisted internal fixation and arthroscopic exploration at the Third Hospital of Hebei Medical University from January 2019 to December 2021. There were 129 males and 59 females, aged 46.7±11.8 years (range, 14-80 years); 115 cases on the left and 73 cases on the right. Schatzker classification of fractures: 81 cases of type II, 15 cases of type III, 23 cases of type IV, 29 cases of type V, and 40 cases of type VI. The time from injury to surgery was 1-14 days, with an average of 10±5 days. The surgery was performed with double reverse traction assisted reduction, locking bone plate and self-breaking compression bolt fixation. Then, arthroscopy was used to explore the quality of fracture reduction, meniscus and ligament damage, and the corresponding intra-articular lesions were treated, such as partial meniscus resection, complete meniscus resection, or suturing. The Rasmussen score was used to evaluate the quality of fracture reduction after surgery, and the Hospital for Special Surgery (HSS) knee joint score was used to evaluate the postoperative function of the knee joint.Results:All patients successfully completed fracture reduction, fixation, and arthroscopic exploration. The average surgical time was 95±21 min (range, 30-120 min); The average intraoperative bleeding volume was 120±58 ml (range, 50-300 ml). All patients were followed up for 10-24 months, with an average of 18±6.5 months. All patients' fractures achieved clinical healing after surgery, with a healing time of 2.5-6.0 months, with an average of 3±2.4 months. Among them, 165 patients (87.8%, 165/188) healed within 3 months after surgery, while the remaining 23 patients healed within 4-6 months after surgery. Arthroscopic exploration revealed that 188 patients had good fracture reduction and a flat articular surface. Among them, 97 cases (51.6%, 97/188) were complicated with meniscus injury, with longitudinal tear (29%, 28/97) being the most common, suture treatment was performed under arthroscopy; the remaining 69 patients underwent partial meniscectomy. All the patient's knee function recovered well at the last follow-up. 29 cases (15.4%, 29/188) were complicated with cruciate ligament injury, none of them underwent primary repair and were fixed with plaster or brace after operation. The Rasmussen score for the final follow-up after surgery was 16.8±2.4 points (range, 6-18 points), with 152 cases being excellent and 36 cases being good, with a 100% excellent and good rate. The HSS knee joint scores were 79.8±9.2 points, 85.1±10.1 points, and 94.9±7.6 points at 3, 6 months after surgery, and at the last follow-up, respectively, with statistically significant differences ( F=52.53, P<0.001). Superficial skin infection occurred in 2 cases after operation, which was cured by regular dressing change and anti-infection treatment with antibiotics. Deep vein thrombosis occurred in 7 cases within 1 week after operation, and low molecular weight heparin anticoagulation therapy was given. Conclusion:After using double reverse traction assisted reduction and internal fixation, arthroscopic examination can not only evaluate the quality of reduction for tibial plateau fractures, but also handle combined meniscus injuries and evaluate the condition of cruciate ligament injuries.
