The safety and efficacy of CM has been practised through experience, rather than nowadays’ modern scientific measurements. In this way, the development of CM has not been keeping pace with the advance in science and technology and the progress in orthodox medicine. In order to meet the requirements of modern science and technology, an evidence based approach must be adopted. Reassurance is needed to convince people for safety and efficacy of CM and give confidence to the evidence based demands ——“Tradition is confirmed by Modern Science” (1) .展开更多

traditional Chinese ...Objective To investigate the therapeutic efficacy and potential mechanisms of fecal microbiota transplantation(FMT)in patients with type 2 diabetes mellitus(T2DM),and to preliminarily identify the traditional Chinese medicine(TCM)syndrome element characteristics of FMT in the treatment of T2DM.Methods Between March 25,2023 and September 30,2024,T2DM patients who met the inclusion and exclusion criteria were enrolled at the Department of Rheumatology and Endocrinology of the Second Affiliated Hospital of Fujian University of Traditional Chinese Medicine.Participants received oral microbiota capsules as an adjunct to metformin therapy.Information obtained by four diagnostic methods of TCM,along with clinical and laboratory parameters,was collected before and after the intervention.Metagenomic sequencing was employed to analyze the gut microbiota,and Spearman correlation analysis was used to explore the relationship between laboratory indicators and differential bacterial genera.According to the post-treatment reduction in glycosylated hemoglobin(HbA1c),patients were categorized into a response(R)group and a non-response(NR)group.Treatment outcomes,safety indicators,gut microbiota changes,and TCM syndrome element features were compared between the two groups.Results A total of 53 T2DM patients were included in the final analysis,and 30 patients were assigned to R group and 23 to NR group.After treatment,the R group exhibited significant reductions in HbA1c,fasting plasma glucose(FPG),and 2-hour postprandial glucose(2hPG)(P<0.05 or P<0.01).The NR group also showed significant decreases in HbA1c and FPG levels P<0.01 or P<0.05.Compared with the NR group,after treatment,FPG level in the R group demonstrated significant reductions(P<0.01).As compared with before treatment,pancreatic islet function demonstrated enhancement in the R group,a significant increase in the 2-hour pastprandial C-peptide(2hC-P)levels in R group(P<0.05),whereas no marked change was observed in the NR group.Regarding body composition indicators,the R group showed significantly lower waist-hip ratio(WHR),visceral fat(VF),and subcutaneous fat(SF)levels compared with the NR group(P<0.01).After treatment,the NR group exhibited a significant elevation in aspartate aminotransferase(AST)levels(P<0.05).Other safety-related indicators fluctuated within normal reference ranges,and no other adverse events,such as diarrhea,fever,or nausea,were reported.Metagenomic sequencing showed that FMT improved the diversity and richness of the gut microbiota,remodeling its overall structure.At the phylum level,the abundance of p_Firmicutes decreased significantly(P<0.01),while the abundances of p_Bacteroidota and p_Proteobacteria increased significantly(P<0.01).At the family level,among the 125 identified taxa,the abundances of f_Bacteroidaceae,f_Lactobacillaceae,and f_Sutterellaceae were significantly elevated,whereas six families,including f_Lachnospiraceae,f_Ruminococcaceae,and f_Coriobacteriaceae,were significantly decreased(all P<0.05).Among the 367 taxa at the genus level,the top 10 differential genera showed significantly increased abundances of g_Bacteroides and g_Sutterella,and significantly decreased abundances in eight genera,including g_Faecalibacterium,g_Ruminococcus,g_Blautia,and g_Collinsella(all P<0.05).Correlation analysis suggested that the phylum p_Bacillota was positively correlated with improvements in T2DM laboratory parameters,g_norank_f_Prevotellaceae was significantly positively correlated with fasting C-peptide(FC-P)and 2hC-P(P<0.05).HbA1c demonstrated a significantly positive correlation with g_Blautia and g_Gemmiger(P<0.05)and a significantly negative correlation with g_Bacteroides and g_Collinsella(P>0.05).Analysis of syndrome element characteristics revealed that the R group was primarily characterized by pathological patterns of dampness,phlegm,and Yang deficiency.Before treatment,statistically significant reductions in syndrome element scores were observed for dampness,Yang deficiency,spleen,phlegm,Qi deficiency,Qi stagnation,and Yin deficiency(P<0.01),as well as for heat and liver(P<0.05).The NR group was mainly featured with Qi deficiency and Yin deficiency.Statistically significant changes in their syndrome element scores after treatment were noted for Qi deficiency(P<0.01),and for spleen,Qi stagnation,liver,and blood deficiency(P<0.05).In this group,the score changes for Yang deficiency,Yin deficiency,heat,and dampness were not statistically significant(P>0.05).Conclusion The principles of syndrome element differentiation can be effectively applied to predict treatment efficacy and facilitate patient selection for FMT in the treatment of T2DM.Patients with T2DM presented with specific TCM syndrome element characteristics,notably dampness,phlegm,and Yang deficiency,represent a highly responsive population to FMT therapy.展开更多

Arterial phase images were acquired with GSI for reconstruction of virtual nonenhanced images and color overlay images. Digital subtraction angiography (DSA) was performed in all these patients. Two blinded and independent readers evaluated the data in two reading sessions; standard nonenhanced, arterial, portalvenous, and delayed phase images were read in session A, and the optimal monochromatic images, iodine/water based images and spectrum features were read in session B. Sensitivity and specificity were calculated with the DSA data as the reference standard. The sensitivity and specificity were compared using the χ<sup>2</sup> test.RESULTS: DSA revealed 154 lesions in 30 patients, and 100 of them had blood supply. Overall sensitivity and specificity were 72% (72/100) and 77.8% (42/54) for session A, and 97% (97/100) and 94.4% (51/54) for session B, respectively. The sensitivity and specificity of the two reading sessions were significantly different (χ<sup>2</sup> = 23.04, χ<sup>2</sup> = 7.11, P < 0.05).CONCLUSION: Compared with conventional CT, GSI could significantly improve the detection of small and multiple lesions without increasing the radiation dose. Based on spectrum features, GSI could assess tumor homogeneity and more accurately identify residual tumors and recurrent or metastatic lesions during efficacy evaluation and follow-up in HCC after TACE treatment.展开更多

Baumannii） is an emerging opportunistic pathogen responsible for hospital-acquired infections, and which now constitutes a sufficiently serious threat to public health to necessitate the development of an effective vaccine. In this study, a recombinant fused protein named OmpK/Omp22 and two individual proteins OmpK and Omp22 were obtained using recombinant expression and Ni-affinity purification. Groups of BALB/c mice were immunized with these proteins and challenged with a clinically isolated strain of A. boumonnii. The bacterial load in the blood, pathological changes in the lung tissue and survival rates after challenge were evaluated. Mice immunized with OmpK/Omp22 fused protein provided significantly greater protection against A. boumonnfi challenge than those immunized with either of the two proteins individually. The results provide novel clues for future design of vaccines against A. boumonnii.展开更多

The occurrence and restoration of CAL in these two groups as well as many laboratory and clinical indexes including average hospital stay (days), total fever duration, defervescence time, platelet count, erythrocyte sedimentation rate, C reactive protein etc. were observed. The incidence of CAL was 39.5 % in the children with KD. In the IVIG+ASA group, the incidence of CAL was 34.3 % and 56.0 % in ASA group respectively (P<0.001). The incidence of CAL was reduced in the group in which 2.0 g/kg or 1.0 g/kg IVIG was administered as compared with the group in which IVIG was administered at a dose ≤0.6 g/kg or ≥3.0 g/kg (P<0.05). CAL occurred less frequently when IVIG was administered at 3-10 days of the course than that when IVIG was administered ≤3 days or >10 days (P<0.05). About 13.4 % of the CAL treated with IVIG was not recovered at the 12 th month of the course, mostly in the groups in which only ASA was administered and IVIG treatment was started 10 days later. The hospital stay (days), defervescence time, total fever duration, platelet count, erythrocyte sedimentation rate and C reactive protein were significantly reduced in IVIG+ASA group as compared with those in the ASA group (P<0.05). IVIG treatment can remarkably shorten the course of patients with KD and decrease the incidence of CAL, but the efficacy of IVIG in the prevention and treatment of KD disease is not as expected by people, therefore, reevaluation of the practical efficacy of IVIG is required.展开更多

Eighty patients with PE diagnosed by computed tomography angiography（CTA） were treated with thrombolysis, anticoagulation only, or surgery/intervention. The clinical efficacy of different treatments were compared and analyzed. Twenty-four out of the 26 patients（92%） in anticoagulation only group showed improvement in CTA and clinical presentations, which was significantly higher than that in the thrombolysis group（87%, n=39, P〈0.05）. However, there was no significant difference in the rate of mortality between thrombolysis group and anticoagulation only group. In the surgery/interventional group（n=15）, the success rate was 47%, and the mortality rate was 14%. Both of them were significantly different from those in thrombolysis and anticoagulation only groups（both P〈0.05）. Log-rank analysis of the data of 5-year follow-up revealed that the survival time in surgery/intervention group was significantly shorter than in the other two groups（P0.05）. It was suggested that it is of importance to choose the appropriate therapeutic regimen for PE patients. Mortality may be reduced and prognosis may be improved with anticoagulation only and thrombolysis therapy.展开更多

文摘Objective:To investigate the clinical efficacy of electrophysiological therapy under different parameter modes in chronic pelvic pain syndrome(CPPS).Methods:A total of 95patients with CPPS from the Department of Urology,First Affiliated Hospital of Jinan University,were selected and treated with electrophysiological therapy.They were randomly divided into three groups:the fixed-parameter AA7 treatment group,the P2+P4 treatment group,and the precision treatment group(individualized parameter treatment).Pain scores of patients in each group were compared before and after treatment,with a pain score of 0 indicating cure.The cure rate of each group was observed.Results:The average ages of the AA7 group,P2+P4 group,and precision treatment group were 34±14.17 years,35.58±12.57 years,and 35.5±11.27 years,respectively.There was no significant difference in age among the three groups(p>0.05).Before treatment,the pain scores of the AA7 group,P2+P4 group,and precision treatment group were 4.14±1.74,4.64±1.72,and 3.50±1.89,respectively,with no significant differences among the groups(p>0.05).After treatment,the pain scores were 0.71±0.99 for the AA7 group(cure rate:57%),0.49±0.79 for the P2+P4 group(cure rate:67%),and 0.50±0.77 for the precision treatment group(cure rate:64%),with no significant differences among the groups(p>0.05).The cure rates for different pain locations were as follows:83%for lower abdominal pain,74%for perineal pain,62%for dysuria,49%for testicular pain,and 75%for inguinal pain.Conclusion:The pathogenesis of CPPS is complex and diverse,with numerous treatment options and uncertain efficacy,posing significant challenges to clinical practice.This study showed that electrophysiological therapy under different parameter modes significantly reduced pain scores before and after treatment,indicating significant therapeutic effects on CPPS.All three modes demonstrated good cure rates.Individualized precision treatment and fixed-mode P2+P4 or AA7 treatment were safe and effective in CPPS treatment and are worth promoting.Fixed-mode P2+P4 and AA7,due to their easier standardization of parameters and patch modes,reduced the learning curve and had better potential for widespread application.
文摘Chinese medicine (CM) has been an experience based practice over the past three thousand years. The safety and efficacy of CM has been practised through experience, rather than nowadays’ modern scientific measurements. In this way, the development of CM has not been keeping pace with the advance in science and technology and the progress in orthodox medicine. In order to meet the requirements of modern science and technology, an evidence based approach must be adopted. Reassurance is needed to convince people for safety and efficacy of CM and give confidence to the evidence based demands ——“Tradition is confirmed by Modern Science” (1) .

文摘BACKGROUND Chronic esophagitis can progress to esophageal cancer via"inflammationdysplasia-cancer"transformation,with nitric oxide(NO)serving as a critical mediator in this process.Traditional diagnostic methods(e.g.,endoscopic biopsy)for esophageal cancer transformation have low sensitivity and require long detection time,while existing fluorescent probes lack specificity and stability for real-time NO monitoring.High-performance fluorescent probes like DAF-FM,with NO-targeting ability,show potential for visual screening and efficacy evaluation but need systematic validation in esophageal cancer models.AIM To validate the applicability of the fluorescent probe DAF-FM for visual screening of esophageal cancer transformation,explore the underlying mechanism of NOregulated transformation,and evaluate the probe’s efficacy in monitoring therapeutic responses.METHODS Laser confocal imaging and flow cytometry were used to analyze DAF-FM’s NO concentration/time-dependent fluorescence response,lysosomal targeting(via Pearson coefficient),and cytotoxicity(with cholecystokinin-8 assay)in esophageal cells.Sprague-Dawley rat esophageal cancer models(normal,esophagitis,esophageal cancer,and drug/radiotherapy intervention)were established to monitor NO dynamics and tumor volume correlation.Clinical diagnostic comparison(50 suspected patients)with endoscopic biopsy/histopathology was conducted using Kolmogorov-Smirnov test and Student’s t-test(P<0.05).Western blot and quantitative realtime polymerase chain reaction were used to explore NO’s role in the nuclear factor-kappa B(NF-κB)pathway.RESULTS DAF-FM exhibited concentration/time-dependent fluorescence with NO(300μM NO:60-minute fluorescence intensity 458±15 arbitrary units,P<0.05)and specific lysosomal targeting(Pearson’s coefficient=0.82±0.03).It had low cytotoxicity(82.3%±4.1%cell viability at 50μM).In rat models,DAF-FM showed that NO was correlated with tumor volume(R²=0.87).Clinically,its sensitivity(92.5%)outperformed endoscopic biopsy(78.3%),with shorter detection time(30 minutes vs 48 hours,P<0.05).Mechanistically,NO regulated transformation via the NF-κB pathway(Pearson’s coefficient=0.78±0.05 between DAF-FM and NF-κB).CONCLUSION DAF-FM is a feasible tool for visual screening of esophageal cancer transformation,enabling real-time NO monitoring,high-sensitivity diagnosis,and therapeutic efficacy evaluation.It provides a new approach for esophageal cancer diagnosis and mechanism research.

文摘Objective To investigate the therapeutic efficacy and potential mechanisms of fecal microbiota transplantation(FMT)in patients with type 2 diabetes mellitus(T2DM),and to preliminarily identify the traditional Chinese medicine(TCM)syndrome element characteristics of FMT in the treatment of T2DM.Methods Between March 25,2023 and September 30,2024,T2DM patients who met the inclusion and exclusion criteria were enrolled at the Department of Rheumatology and Endocrinology of the Second Affiliated Hospital of Fujian University of Traditional Chinese Medicine.Participants received oral microbiota capsules as an adjunct to metformin therapy.Information obtained by four diagnostic methods of TCM,along with clinical and laboratory parameters,was collected before and after the intervention.Metagenomic sequencing was employed to analyze the gut microbiota,and Spearman correlation analysis was used to explore the relationship between laboratory indicators and differential bacterial genera.According to the post-treatment reduction in glycosylated hemoglobin(HbA1c),patients were categorized into a response(R)group and a non-response(NR)group.Treatment outcomes,safety indicators,gut microbiota changes,and TCM syndrome element features were compared between the two groups.Results A total of 53 T2DM patients were included in the final analysis,and 30 patients were assigned to R group and 23 to NR group.After treatment,the R group exhibited significant reductions in HbA1c,fasting plasma glucose(FPG),and 2-hour postprandial glucose(2hPG)(P<0.05 or P<0.01).The NR group also showed significant decreases in HbA1c and FPG levels P<0.01 or P<0.05.Compared with the NR group,after treatment,FPG level in the R group demonstrated significant reductions(P<0.01).As compared with before treatment,pancreatic islet function demonstrated enhancement in the R group,a significant increase in the 2-hour pastprandial C-peptide(2hC-P)levels in R group(P<0.05),whereas no marked change was observed in the NR group.Regarding body composition indicators,the R group showed significantly lower waist-hip ratio(WHR),visceral fat(VF),and subcutaneous fat(SF)levels compared with the NR group(P<0.01).After treatment,the NR group exhibited a significant elevation in aspartate aminotransferase(AST)levels(P<0.05).Other safety-related indicators fluctuated within normal reference ranges,and no other adverse events,such as diarrhea,fever,or nausea,were reported.Metagenomic sequencing showed that FMT improved the diversity and richness of the gut microbiota,remodeling its overall structure.At the phylum level,the abundance of p_Firmicutes decreased significantly(P<0.01),while the abundances of p_Bacteroidota and p_Proteobacteria increased significantly(P<0.01).At the family level,among the 125 identified taxa,the abundances of f_Bacteroidaceae,f_Lactobacillaceae,and f_Sutterellaceae were significantly elevated,whereas six families,including f_Lachnospiraceae,f_Ruminococcaceae,and f_Coriobacteriaceae,were significantly decreased(all P<0.05).Among the 367 taxa at the genus level,the top 10 differential genera showed significantly increased abundances of g_Bacteroides and g_Sutterella,and significantly decreased abundances in eight genera,including g_Faecalibacterium,g_Ruminococcus,g_Blautia,and g_Collinsella(all P<0.05).Correlation analysis suggested that the phylum p_Bacillota was positively correlated with improvements in T2DM laboratory parameters,g_norank_f_Prevotellaceae was significantly positively correlated with fasting C-peptide(FC-P)and 2hC-P(P<0.05).HbA1c demonstrated a significantly positive correlation with g_Blautia and g_Gemmiger(P<0.05)and a significantly negative correlation with g_Bacteroides and g_Collinsella(P>0.05).Analysis of syndrome element characteristics revealed that the R group was primarily characterized by pathological patterns of dampness,phlegm,and Yang deficiency.Before treatment,statistically significant reductions in syndrome element scores were observed for dampness,Yang deficiency,spleen,phlegm,Qi deficiency,Qi stagnation,and Yin deficiency(P<0.01),as well as for heat and liver(P<0.05).The NR group was mainly featured with Qi deficiency and Yin deficiency.Statistically significant changes in their syndrome element scores after treatment were noted for Qi deficiency(P<0.01),and for spleen,Qi stagnation,liver,and blood deficiency(P<0.05).In this group,the score changes for Yang deficiency,Yin deficiency,heat,and dampness were not statistically significant(P>0.05).Conclusion The principles of syndrome element differentiation can be effectively applied to predict treatment efficacy and facilitate patient selection for FMT in the treatment of T2DM.Patients with T2DM presented with specific TCM syndrome element characteristics,notably dampness,phlegm,and Yang deficiency,represent a highly responsive population to FMT therapy.
文摘An acute skin injury model using continuous tape tearing was established,and studies the application of this model in the evaluation of soothing effects through instrument evaluation.30 healthy adult subjects were selected as the research subjects,and an acute skin model was established on the forearm flexion side of the subjects.The skin color a^(*)value and transdermal water loss rate(TEWL)value of the blank and experimental groups were tested using instruments.The results showed that at 15 and 30 minutes after using the sample,the growth values of a^(*)value and TEWL value in the experimental group were significantly lower than those in the blank group(P<0.05),the acute skin lesion model can effectively evaluate the soothing effect of cosmetics.

文摘In 2013,peste des petits ruminants(PPR)re-emerged in China and spread to the majority of provinces across the country.The disease was effectively controlled through a vaccination campaign employing live attenuated vaccines,although sporadic cases still occurred.However,limited information is currently available regarding the peste des petits ruminants virus(PPRV)endemic in China.Here,a PPRV strain(HLJ/13)was isolated from a field sample in China using Vero cells expressing goat signalling lymphocyte activation molecule.Phylogenetic analysis indicated that HLJ/13 belonged to lineage IV.Subsequent intranasal and subcutaneous inoculation of goats with a dose of 2×10~6 TCID50of HLJ/13 resulted in the development of typical clinical symptoms of PPR,including pyrexia,ocular and nasal discharges,stomatitis,and diarrhea.All infected goats succumbed to the disease by day 8.To gain further insight,viral loading,pathological examination and immunohistochemical analyses were conducted,elucidating the main targets of HLJ/13 as the respiratory system,digestive tract and lymphoid organs.Employing the goat infection model established above,the goat poxvirus-vectored PPR vaccine,which was previously developed and could be used as DIVA(differentiating infected from vaccinated animals)vaccine,provided complete protection against the challenge of HLJ/13.It is important to note that this study represents the first comprehensive report delineating the biology and pathogenicity characterization,and infection model of PPRV isolated in China.
文摘BACKGROUND Gastric cancer(GC)remains a significant global health challenge,with high incidence and mortality rates.Neoadjuvant chemotherapy is increasingly used to improve surgical outcomes and long-term survival in advanced cases.However,individual responses to treatment vary widely,and current imaging methods often fall short in accurately predicting efficacy.Advanced imaging techniques,such as computed tomography(CT)3D reconstruction and texture analysis,offer potential for more precise assessment of therapeutic response.AIM To explore the application value of CT 3D reconstruction volume change rate,texture feature analysis,and visual features in assessing the efficacy of neoadjuvant chemotherapy for advanced GC.METHODS A retrospective analysis was conducted on the clinical and imaging data of 97 patients with advanced GC who received S-1 plus Oxaliplatin combined chemotherapy regimen neoadjuvant chemotherapy from January 2022 to March 2024.CT texture feature analysis was performed using MaZda software,and ITK-snap software was used to measure the tumor volume change rate before and after chemotherapy.CT visual features were also evaluated.Using postoperative pathological tumor regression grade(TRG)as the gold standard,the correlation between various indicators and chemotherapy efficacy was analyzed,and a predictive model was constructed and internally validated.RESULTS The minimum misclassification rate of texture features in venous phase CT images(7.85%)was lower than in the arterial phase(13.92%).The volume change rate in the effective chemotherapy group(75.20%)was significantly higher than in the ineffective group(41.75%).There was a strong correlation between volume change rate and TRG grade(r=-0.886,P<0.001).Multivariate analysis showed that gastric wall peristalsis(OR=0.286)and thickness change rate≥40%(OR=0.265)were independent predictive factors.Receiver operating characteristic curve analysis indicated that the volume change rate[area under the curve(AUC)=0.885]was superior to the CT visual feature model(AUC=0.795).When the cutoff value was 82.56%,the sensitivity and specificity were 85.62%and 96.45%,respectively.CONCLUSION The CT 3D reconstruction volume change rate can serve as a preferred quantitative indicator for evaluating the efficacy of neoadjuvant chemotherapy in GC.Combining it with a CT visual feature predictive model can further improve the accuracy of efficacy evaluation.
文摘The soothing efficacy of baby moisturizer was evaluated by analyzing the changes of inflammatory cytokines in vitro and human efficacy tests.RAW264.7 cells were induced by Lipopolysaccharide(LPS) to establish a cell inflammation model in vitro,and the inflammatory cytokines of Interleukin-6 (IL-6) and NO were detected to observe the inhibitory effect of baby moisturizer in vitro.The non-toxic concentration of baby moisturizer was detected by MTT assay,the level of IL-6 in RAW264.7 cells supernatant was detected by ELISA kits,and the level of NO in RAW 264.7 cells supernatant was detected by Griess reagent.Dexamethasone was used as the positive control.At the same time,the hydration of the stratum corneum,transepidermal water loss (TEWL),erythema index,the redness of skin (a^(*) value) and the proportion of redness area in facial cheekbones were detected after using the baby moisturizer for 28 days.The experiment results showed that the baby moisturizer at a non-toxic concentration of 0.3 mg/mL,could significantly reduce IL-6 and NO in RAW264.7 cells supernatant,meanwhile it could significantly enhance the hydration of the stratum corneum,and reduce the TEWL,erythema index,the redness of skin (a^(*) value) and the proportion of redness area.In conclusion,the baby moisturizer (0.3 mg/mL) can restrain inflammatory cytokines in vitro and can also significantly improve human facial skin irritation,which can be considered to have soothing efficacy.
文摘AIM: To assess the value of gemstone spectral imaging (GSI) in efficacy evaluation in hepatocellular cancer (HCC) after transcatheter arterial chemoembolization (TACE) treatment.METHODS: Thirty patients with HCC underwent GSI, including nonenhanced, arterial, portalvenous and delayed phase scans, after TACE treatment. Arterial phase images were acquired with GSI for reconstruction of virtual nonenhanced images and color overlay images. Digital subtraction angiography (DSA) was performed in all these patients. Two blinded and independent readers evaluated the data in two reading sessions; standard nonenhanced, arterial, portalvenous, and delayed phase images were read in session A, and the optimal monochromatic images, iodine/water based images and spectrum features were read in session B. Sensitivity and specificity were calculated with the DSA data as the reference standard. The sensitivity and specificity were compared using the χ<sup>2</sup> test.RESULTS: DSA revealed 154 lesions in 30 patients, and 100 of them had blood supply. Overall sensitivity and specificity were 72% (72/100) and 77.8% (42/54) for session A, and 97% (97/100) and 94.4% (51/54) for session B, respectively. The sensitivity and specificity of the two reading sessions were significantly different (χ<sup>2</sup> = 23.04, χ<sup>2</sup> = 7.11, P < 0.05).CONCLUSION: Compared with conventional CT, GSI could significantly improve the detection of small and multiple lesions without increasing the radiation dose. Based on spectrum features, GSI could assess tumor homogeneity and more accurately identify residual tumors and recurrent or metastatic lesions during efficacy evaluation and follow-up in HCC after TACE treatment.

文摘Cell mechanics is essential to cell development and function,and its dynamics evolution reflects the physiological state of cells.Here,we investigate the dynamical mechanical properties of single cells under various drug conditions,and present two mathematical approaches to quantitatively characterizing the cell physiological state.It is demonstrated that the cellular mechanical properties upon the drug action increase over time and tend to saturate,and can be mathematically characterized by a linear timeinvariant dynamical model.It is shown that the transition matrices of dynamical cell systems significantly improve the classification accuracies of the cells under different drug actions.Furthermore,it is revealed that there exists a positive linear correlation between the cytoskeleton density and the cellular mechanical properties,and the physiological state of a cell in terms of its cytoskeleton density can be predicted from its mechanical properties by a linear regression model.This study builds a relationship between the cellular mechanical properties and the cellular physiological state,adding information for evaluating drug efficacy.
文摘BACKGROUND Cognitive-behavioral therapy(CBT)and habit reversal training(HRT)have shown application potential in addressing tic symptoms and comorbid psychiatric conditions.Despite their theoretical potential,empirical evidence on their combined efficacy remains limited.AIM To evaluate the efficacy of CBT combined with HRT on anxiety disorders in children with Tourette’s syndrome(TS).METHODS Clinical data of children with TS admitted to our hospital from January 2022 to June 2023 were collected,and the patients were grouped into the conventional therapy(control)group and the CBT combined with HRT group.Baseline charac-teristics,anxiety scores,tic severity scores,treatment adherence,and parental satisfaction were assessed.Statistical analysis was performed using t-tests,chi-square tests,and correlation analysis.RESULTS A total of 136 patients,including 65 patients in the control group and 71 patients in the CBT combined with HRT group,were included.The CBT combined with HRT group showed remarkable improvements compared with the control group.Post-intervention assessment revealed a decrease in anxiety scores from 63.52±1.81 to 40.53±1.64(t=2.022,P=0.045),and the Yale Global Tic Severity Scale total score decreased from 22.14±5.67 to 16.28±4.91(t=2.288,P=0.024).Treatment adherence was significantly higher in the CBT combined with HRT group(85.47±7.62%)compared with the control group(82.32±6.54%;t=2.596,P=0.010).Parental satisfaction scores were also higher in the CBT combined with HRT group(8.69±1.77)compared with the control group(7.87±1.92;t=2.592,P=0.011).CONCLUSION This study demonstrates that CBT combined with HRT significantly reduces anxiety symptoms and tic severity in children with TS,with higher treatment adherence and parental satisfaction.These findings support the potential application of this comprehensive therapeutic approach for TS treatment.

文摘Acinetobocter baumannfi （A. Baumannii） is an emerging opportunistic pathogen responsible for hospital-acquired infections, and which now constitutes a sufficiently serious threat to public health to necessitate the development of an effective vaccine. In this study, a recombinant fused protein named OmpK/Omp22 and two individual proteins OmpK and Omp22 were obtained using recombinant expression and Ni-affinity purification. Groups of BALB/c mice were immunized with these proteins and challenged with a clinically isolated strain of A. boumonnii. The bacterial load in the blood, pathological changes in the lung tissue and survival rates after challenge were evaluated. Mice immunized with OmpK/Omp22 fused protein provided significantly greater protection against A. boumonnfi challenge than those immunized with either of the two proteins individually. The results provide novel clues for future design of vaccines against A. boumonnii.

文摘Pterostilbene(PT),a lipid-soluble polyphenol known for its antioxidant,anticancer,and various other biological properties,holds potential as an active ingredient in cosmetics for its anti-wrinkle and skin-whitening effects.However,its application is limited by its low water solubility and poor penetration through the stratum corneum.To address these limitations,this study initially prepared Pterostilbene nanoliposomes(PT-NLPs)using a high shear-microjet homogenization treatment method,because of the distinctive hydrophilic and hydrophilic properties of the liposomes.The stability under different storage conditions of the PT-NLPs was evaluated by investigating the alterations of the particle size,PDI,Zeta potential and surface morphology,combined with the test results of Lumisizer stability analyzer.Finally,the comprehensive performance of PT-NLPs was evaluated through in vitro dermal and transdermal testing,human testing,and instrument testing.The results showed that the PT-NLPs treated by the high shear-microjet homogenisation method proposed in this paper possessed a 1.7-fold increase in the retention performance compared with the free PT solution,and no penetration occurred on the blood-brain barrier,indicating that PT-NLPs would not cause toxicity to the organism.The human efficacy evaluation found that the PT-NLPs whitening serum could improve skin dullness,brighten skin tone,and improve skin sensitivity after 14 days of use.The high shear-microjet homogenisation method proposed in this paper for the treatment of PT-NLPs improved the transdermal delivery properties of PT.The process has a broad application prospect in the fields of medicine and cosmetics.

文摘In order to objectively evaluate the efficacy of intravenous gammaglobulin (IVIG) in the prevention and treatment of coronary artery lesion (CAL) in Kawasaki disease (KD) and the related factors influencing the IVIG efficacy, 314 children with KD were reviewed retrospectively and comparatively and were divided into IVIG plus aspirin group and ASA group. The occurrence and restoration of CAL in these two groups as well as many laboratory and clinical indexes including average hospital stay (days), total fever duration, defervescence time, platelet count, erythrocyte sedimentation rate, C reactive protein etc. were observed. The incidence of CAL was 39.5 % in the children with KD. In the IVIG+ASA group, the incidence of CAL was 34.3 % and 56.0 % in ASA group respectively (P<0.001). The incidence of CAL was reduced in the group in which 2.0 g/kg or 1.0 g/kg IVIG was administered as compared with the group in which IVIG was administered at a dose ≤0.6 g/kg or ≥3.0 g/kg (P<0.05). CAL occurred less frequently when IVIG was administered at 3-10 days of the course than that when IVIG was administered ≤3 days or >10 days (P<0.05). About 13.4 % of the CAL treated with IVIG was not recovered at the 12 th month of the course, mostly in the groups in which only ASA was administered and IVIG treatment was started 10 days later. The hospital stay (days), defervescence time, total fever duration, platelet count, erythrocyte sedimentation rate and C reactive protein were significantly reduced in IVIG+ASA group as compared with those in the ASA group (P<0.05). IVIG treatment can remarkably shorten the course of patients with KD and decrease the incidence of CAL, but the efficacy of IVIG in the prevention and treatment of KD disease is not as expected by people, therefore, reevaluation of the practical efficacy of IVIG is required.

文摘An optimal therapy for pulmonary embolism（PE） was explored by comparing three different methods in order to alleviate the sufferings of PE patients and reduce the mortality. Eighty patients with PE diagnosed by computed tomography angiography（CTA） were treated with thrombolysis, anticoagulation only, or surgery/intervention. The clinical efficacy of different treatments were compared and analyzed. Twenty-four out of the 26 patients（92%） in anticoagulation only group showed improvement in CTA and clinical presentations, which was significantly higher than that in the thrombolysis group（87%, n=39, P〈0.05）. However, there was no significant difference in the rate of mortality between thrombolysis group and anticoagulation only group. In the surgery/interventional group（n=15）, the success rate was 47%, and the mortality rate was 14%. Both of them were significantly different from those in thrombolysis and anticoagulation only groups（both P〈0.05）. Log-rank analysis of the data of 5-year follow-up revealed that the survival time in surgery/intervention group was significantly shorter than in the other two groups（P0.05）. It was suggested that it is of importance to choose the appropriate therapeutic regimen for PE patients. Mortality may be reduced and prognosis may be improved with anticoagulation only and thrombolysis therapy.

文摘Background:The efficacy of combining immune checkpoint inhibitors(ICIs)with chemotherapy in neoadjuvant therapy for locally advanced gastric cancer has been explored.However,limited research exists on its effectiveness in conversion therapy,and its superiority over standalone chemotherapy remains to be elucidated.This study aims to investigate the efficacy and survival outcomes of patients treated with ICIs in combination with conversion therapy for locally advanced gastric cancer.Methods:Retrospective data from patients with locally advanced gastric cancer treated with either oxaliplatin+S-1(SOX)alone or in combination with ICIs in conversion therapywere collected.Clinical andpathological characteristics,disease-free survival,andefficacy assessments in nonoperable patients were compared between the 2 treatment groups.Efficacy was further evaluated through dynamic changes in serum markers,and patients’quality of life was assessed using the QLQ-STO22(Gastric Cancer–Specific Quality of Life Questionnaire)quality-of-life measurement scale.Results:A total of 140 patients underwent conversion therapy:80 in the SOX alone group and 60 in the SOX combined with the ICIs group.There were no significant differences in baseline characteristics between the 2 groups.Compared with the SOX alone group,the SOX combined with ICIs group exhibited a higher conversion rate(83.3%vs 75%,P=0.23),R0 resection rate(90.0%vs 83.3%,P=0.31),pathological complete response(pCR)rate(18%vs 5%,P=0.02),median disease-free survival(21.4 vs 16.9 months,P=0.007),the objective response rate in nonoperable patients(60%vs 40%,P=0.301),and median progression-free survival time(7.9 vs 5.7 months,P=0.009).The QLQ-STO22 quality-of-life assessment revealed statistically significant improvements in pain,swallowing difficulties,and dietary restrictions in the combination therapy group compared with those in the monotherapy group.The enhanced efficacy of immune combination with SOX is evident,as demonstrated by the significantly prolonged surgical duration in operated patients(206.6±26.6 min vs 197.8±19.8 min,P=0.35)and intraoperative blood loss(158.9±21.2 mL vs 148.9±25.1 mL,P=0.59).No significant differences were observed in postoperative complications.Conclusions:Compared with the SOX conversion therapy regimen,SOX combined with ICIs demonstrated higher conversion rates,R0 resection rates,pathological response rates,and disease-free survival without increasing surgical difficulty or complications.Nonoperable patients also experienced longer progression-free survival and objective response rates.

文摘[Objectives]To evaluate the intervention effect and safety of self-created Lung Health Breathing Exercise on TCM syndromes,6-min walk test(6MWT)and quality of life in patients with stable chronic obstructive pulmonary disease(COPD).[Methods]76 cases of outpatient or inpatient patients who were diagnosed with stable COPD in Nanchong Traditional Chinese Medicine Hospital from January 2020 to March 2021 were selected,randomly divided into experimental group and control group,38 cases in each group.Both groups were given conventional western medicine treatment and nursing measures.The experimental group was added with the self-created Lung Health Breathing Exercise.After 12 weeks of treatment,the TCM syndrome score,6MWT distance,quality of life score and the incidence of adverse events were observed in the both groups.[Results]After treatment,the 6MWT distance and quality of life scores in both groups were significantly improved(P<0.01),and the TCM syndrome scores were significantly lower than those before treatment(P<0.01).[Conclusions]Lung Health Breathing Exercise can benefit patients in terms of symptom improvement,quality of life and exercise ability,and is a safe and effective rehabilitation measure for patients with stable COPD.
