ObjectiveTo explore the changes in color， odor and chemical components during wine-processing of Chuanxiong Rhizoma（CR）， identify differential markers， and provide a basis for standardizing the process and establishing quality standards. MethodsFifteen batches of CR samples from 4 producing areas were collected. Colorimeter and electronic nose were used to detect the color changes and odor components of CR before and after wine-processing. Multivariate statistical methods including partial least squares-discriminant analysis（PLS-DA）， principal component analysis（PCA）， discriminant factor analysis（DFA） and Fisher discriminant analysis were applied to identify wine-processed CR at different processing stages and establish discriminant models， and differential components were screened out based on variable importance in the projection（VIP） value1. Then， high performance liquid chromatography（HPLC） was employed to detect the content changes of four components（ferulic acid， senkyunolide I， senkyunolide A and ligustilide） during the processing stages. ResultsThe differences of wine-processed CR at various stages were primarily reflected in color parameters L^*（brightness value）， a^*（red-green value） and b^*（yellow-blue value）. Based on chromaticity differences， the color reference ranges were established for moderately processed CR， including L^* of 46.75-48.24， a^* of 5.37-6.07 and b^* of 20.32-21.70. In odor analysis， DFA revealed significant differences among processing stages， and 11 odor markers were identified， with four differential markers（4-hydroxy-3-butylphthalide， isopropyl butyrate， L-limonene and 1-methoxyhexane） based on VIP values. HPLC results showed that there was no significant difference of the four components except for ligustilide in wine-processed CR at different stages. ConclusionThis study achieved rapid identification of wine-processed CR with different processing degrees by electronic sensory technology and differential component content detection， with discrimination accuracy rates of 92.4% and 93.272% for color and odor， respectively. This paper also established the reference ranges of main colorimetric parameters for wine-processed CR at different stages， and four differential components were screened out， providing a basis for standardizing the processing of wine-processed CR and establishing quality standards for this decoction pieces.

Objective To explore the clinical characteristics of patients with diffuse large B-cell lymphoma (DLBCL) accompanied with KMT2D gene mutation and the impact of its co-mutated genes on prognosis. Methods Clinical data of 155 newly diagnosed DLBCL patients were obtained. The second-generation sequencing method was used to detect 475 hotspot genes, including KMT2D mutation. Patients were divided into the KMT2D mutation group and KMT2D wild-type group based on the presence or absence of KMT2D gene mutation. Clinical characteristics, differences in co-mutated genes, and survival differences between the two groups were compared. Results The frequency of KMT2D mutation was 31%, which is predominantly observed in elderly patients (P=0.07) and less in the double-expressor phenotype (P=0.07). Compared with the KMT2D wild-type group, KMT2D gene mutation was associated with higher co-mutation rates of CDKN2A (OR=2.82, P=0.01) and BCL2 (OR=3.84, P=0.016), while being mutually exclusive with MYC gene mutation (OR=0.11, P=0.013). In univariate survival analysis, no statistically significant difference in overall survival (OS) was found between the KMT2D mutation group and the wild-type group (P=0.54). Further analysis of the prognostic significance of KMT2D with other gene mutations indicated that patients with KMT2D^mutBTG2^mut had poorer OS than those with KMT2D^wt BTG2^mut (P=0.07) and KMT2D^wt BTG2^wt (P=0.05). On the contrary, patients with KMT2D^mut CD79B^mut had better OS than those with KMT2D^mut CD79B^wt (P=0.09), with no prognostic impact observed for other co-mutated genes. Multivariate Cox regression analysis revealed that Ann Arbor stages Ⅲ and Ⅳ (HR=2.751, 95%CI: 1.169-6.472, P=0.02), elevated LDH levels (HR=2.461, 95%CI: 1.396-4.337, P=0.002), Ki-67 index>80% (HR=1.875, 95%CI: 1.066-3.299, P=0.029), and KMT2D^mutBTG2^mut(HR=4.566, 95%CI: 1.348-15.471, P=0.015) were independent risk factors for OS in patients with DLBCL (P<0.05). Conclusion DLBCL patients with KMT2D mutation often have multiple gene mutations, among which patients with a co-mutated BTG2 gene have poor prognosis.

Objective To establish typical values for interventional diagnosis and treatment at our institution, use these values as a tool to evaluate patient medical exposure doses, and optimize radiation protection measures. Methods From June to December 2023, we collected information on 593 adult cardiovascular interventional diagnosis and treatment surgeries, including surgery type, equipment model, air kerma-area product (KAP), incident reference point air kerma (K_a,r), perspective time (FT), and exposure mode. Results The typical value of cardiovascular interventional diagnosis at our institution in 2023 was 27.5 Gy·cm². The typical value of cardiovascular interventional treatment was 70.0 Gy·cm². The FT, KAP, and K_a,r of interventional surgeries were significantly higher than those of interventional diagnosis (P < 0.01). There were significant correlations between FT, KAP, and K_a,r (P < 0.01). Conclusion The results of this study were slightly different from those of other studies. They provide typical data and reference values for cardiovascular interventional diagnosis and treatment dose levels in Beijing and are helpful for dose optimization between different medical institutions.

ObjectiveTo investigate the clinical features and outcomes of recompensation in patients with autoimmune hepatitis （AIH）-related decompensated cirrhosis， to identify independent predictive factors， and to construct a nomogram prediction model for the probability of recompensation. MethodsA retrospective cohort study was conducted among the adult patients with AIH-related decompensated cirrhosis who were admitted to The Fifth Medical Center of PLA General Hospital from January 2015 to August 2023 （n=211）. The primary endpoint was achievement of recompensation， and the secondary endpoint was liver-related death or liver transplantation. According to the outcome of the patients at the end of the follow-up， the patients were divided into the recompensation group （n=16） and the persistent decompensation group（n=150）.The independent-samples t test was used for comparison of normally distributed continuous data with homogeneity of variance， and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data with heterogeneity of variance； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups； the Kaplan-Meier method was used for survival analysis； the Cox proportional-hazards regression model was used to identify independent predictive factors， and a nomogram model was constructed and validated. ResultsA total of 211 patients were enrolled， with a median age of 55.0 years and a median follow-up time of 44.0 months， and female patients accounted for 87.2%. Among the 211 patients， 61 （with a cumulative proportion of 35.5%） achieved recompensation. Compared with the persistent decompensation group， the recompensation group had significantly higher white blood cell count， platelet count （PLT）， total bilirubin （TBil）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， total bile acid， prothrombin time， international normalized ratio （INR）， SMA positive rate， Model for End-Stage Liver Disease （MELD） score， Child-Pugh score， and rate of use of glucocorticoids （all P0.05）， as well as significantly lower age at baseline， number of complications， and death/liver transplantation rate （all P0.05）. At 3 and 12 months after treatment， the recompensation group had continuous improvements in AST， TBil， INR， IgG， MELD score， and Child-Pugh score， which were significantly lower than the values in the persistent decompensation group （all P0.05）， alongside with continuous increases in PLT and albumin， which were significantly higher than the values in the persistent decompensation group （P0.05）. The multivariate Cox regression analysis showed that baseline ALT （hazard ratio ［HR］=1.067， 95% confidence interval ［CI］： 1.010 — 1.127， P=0.021）， IgG （HR=0.463，95%CI：0.258 — 0.833， P=0.010）， SMA positivity （HR=3.122，95%CI：1.768 — 5.515， P0.001）， and glucocorticoid therapy （HR=20.651，95%CI：8.744 — 48.770， P0.001） were independent predictive factors for recompensation， and the nomogram model based on these predictive factors showed excellent predictive performance （C-index=0.87，95%CI：0.84 — 0.90）. ConclusionAchieving recompensation significantly improves clinical outcomes in patients with AIH-related decompensated cirrhosis. Baseline SMA positivity， a high level of ALT， a low level of IgG， and corticosteroid therapy are independent predictive factors for recompensation. The predictive model constructed based on these factors can provide a basis for decision-making in individualized clinical management.

Objective To investigate the effect of lidocaine medicated plaster （LMP） combined with pregabalin （PGB） on patients with postherpetic neuralgia （PHN）, and the impact on serum pain mediators. Methods 108 PHN patients admitted in our hospital from January 2024 to December 2024 were selected and grouped according to the time point of receiving treatment, 54 PHN patients treated with PGB from January 2024 to June 2024 were included in the PGB group, and 54 PHN patients treated with LMP on top of the PGB group from July 2024 to December 2024 were included in the PGB+LMP group. Comparisons were made between the two groups in terms of pain score, serum pain mediator levels, dosage of PGB, and incidence of adverse reactions. Results After 4 weeks of treatment, both groups showed a decrease in Pain Rating Index scores （sensory score and affective score）, Present Pain Intensity score, Visual Analog Scale score, and total score. Meanwhile, above scores of the PGB+LMP group were lower than those of the PGB group （P<0.05）. After 4 weeks of treatment, the levels of substance P（SP） and neuropeptide Y （NPY） in both groups were lower than those before treatment, while serum 5-hydroxytryptamine （5-HT） levels were higher than those before treatment. Moreover, the levels of SP and NPY were lower, and 5-HT level was higher in the PGB+LMP group than in the PGB group （P<0.05）. The dosages of PGB in the PGB+LMP group at T1, T, T3 and T4 were significantly lower than those in the PGB group （P<0.05）. The incidence of adverse reactions was 1.85%（1/54） in the PGB+LMP group. Compared to 5.56%（3/54） in the PGB group, and the difference was not statistically significant （P>0.05）. Conclusion LMP combined with PGB was effective in the treatment of patients with PHN, which could effectively alleviate pain and lower the levels of serum pain mediators, with good safety.

Objective To investigate the efficacy and safety of interventional therapy for bronchopleural fistula(BPF).Methods A total of 172 patients with confirmed BPF were treated with continuous negative pressure drainage(CNPD)and/or airway stent occlusion therapy.The clinical data were collected,and its effectiveness and safety were analyzed.Results In 5-7 days after interventional treatment,the pneumonia severity index(PSI)decreased significantly,and successful drainage was achieved in 166 patients(96.5％).One month after interventional therapy,the lung volume was remarkably increased.The median clinical healing time of interventional therapy was 9.0 months(95％CI=6.18-1 1.83).Multivariate analysis of the Cox proportional hazards model showed that the diagnosis time(HR=0.53,95％CI=0.38-0.74,P＜0.01)and fistula size(HR=0.74,95％CI=0.55-0.99,P=0.04)were significantly correlated with the clinical healing time.Conclusion For the treatment of BPF,CNPD and/or airway stent occlusion has several advantages such as accurate operation,minimally invasive,safe and effective.It can quickly improve the symptoms and quality of life,and prolong survival,therefore,it is worthy of clinical promotion and application.(J Intervent Radiol,2024,33:641-645)

Objective To explore the comprehensive analysis of mRNA/microRNA(miRNA)networks in peripheral blood of patients with schizophrenia.Methods A total of 6 schizophrenic patients treated in a hos-pital from December 2022 to February 2023 were included as the experimental group and 4 volunteers as the control group.Blood samples of the two groups were collected and the mRNA and miRNA expression levels were detected by RNA-seq technique.Finally,the gene set GSE145554 in Gene Expression Omnibus was used for bioinformatics verification analysis.Results Compared with the control group,a total of 2 133 mRNA differences were detected in the experimental group,including 1 410 mRNA up-regulated and 723 mRNA down-regulated.There were 150 differential miRNAs,including 72 up-regulated miRNAs and 78 down-regula-ted miRNAs.Kyoto Encyclopedia of Genes and Genomes and Gene Ontology enrichment biological processes and signaling pathways mainly include mammalian target of rapamycin(mTOR)signaling pathway,phos-phatidylinositide 3-kinases(PI3K)-serine/threonine-protein kinase(AKT)signaling pathway,necroptosis,and protein processing in the endoplasmic reticulum endoplasmic reticulum signaling pathways etc.Conclusion PI3K-AKT,mTOR,necroptosis and protein processing in endoplasmic reticulum signaling pathways are in-volved in the occurrence and development of schizophrenia,and provide a new research direction for the pre-vention,diagnosis and treatment of schizophrenia.

Objective To explore the predictive value of serum soluble osteoclast-associated receptor(sOSCAR)for cardiovascular adverse events after percutaneous coronary intervention(PCI)in patients with acute non-ST segment elevation acute myocardial infarction(NSTEMI).Methods From January 2020 to Jan-uary 2022,124 NSTEMI patients admitted to Weifang People's Hospital who underwent PCI were selected as the NSTEMI group,and another 100 healthy volunteers in the same period were selected as the control group.The NSTEMI patients were classified into 31 cases of poor prognosis and 93 cases of good prognosis group ac-cording to whether major adverse cardiovascular events occurred 1 year after PCI.Multivariate Logistic regres-sion model was constructed to analyze the factors affecting the prognosis of NSTEMI patients after PCI,and receiver operating characteristic(ROC)curve was drawn to analyze the predictive value of sOSCAR level on the prognosis of NSTEMI patients after PCI.Results Compared with the control group,serum angiopoietin-2(Ang-2)levels were increased and sOSCAR levels were decreased in the NSTEMI group(P＜0.05).At 1-year follow-up,the incidence of poor prognosis after PCI in 124 NSTEMI patients was 25.00％(31/124).Multivariate Logistic regression analysis showed that increasing age and Ang-2 were independent risk factors affecting the prognosis after PCI in patients with NSTEMI(P＜0.05),and elevated left ventricular ejection fraction and elevated sOSCAR were independent protective factors(P＜0.05).ROC curve analysis showed that the area under the curve of serum Ang-2 and sOSCAR levels combined to predict the prognosis after PCI in NSTEMI patients was 0.865,which was greater than that of serum Ang-2 and sOSCAR levels alone,which were 0.791 and 0.786(P＜0.05).Conclusion Serum sOSCAR level is decreased in patients with NSTEMI and is closely related to the poor prognosis of patients after PCI.Serum sOSCAR combined with Ang-2 has a high predictive value for the poor prognosis of NSTEMI patients after PCI.

Objective:To investigate the effect of 980 nm semiconductor laser preablation of urethra mucosa at the prostatic tip in small volume benign prostatic hyperplasia (BPH).Methods:The case data of 120 patients diagnosed with small volume BPH in the Yan′an University Affiliated Hospital from June 2020 to June 2022 were retrospectively analyzed, and they were divided into improved group and conventional group according to different treatment methods, with 60 cases in each group. Patients in the improved group were treated with 980 nm semiconductor laser preablation of urethra mucosa at the prostatic tip, and patients in the conventional group were treated with 980 nm semiconductor laser vaporization of prostate. The sexual function of the patients was evaluated by the international erectile function index-5(IIEF-5) score, erectile hardness score (EHS) and retrograde ejaculation before surgery and 1, 3, 6, and 12 months after surgery. International prostate symptom scale (IPSS), quality of life (QOL) score, the maximum urine flow rate (Qmax) and postvoid residual urine (PVR) were used to evaluate urinary control function. The incidence of urinary incontinence, bladder neck contracture and other complications were compared between the two groups. Measurement data were expressed as mean±standard deviation ( ± s), and t-test was used for comparison between groups. The count data were expressed as cases and percentage, and Chi-square test was used for comparison between groups. Results:There was no significant difference in PVR, Qmax, IPSS score, QOL score, IIEF-5 score and EHS score between two groups ( P>0.05). In terms of PVR, Qmax, IPSS score, QOL score, IIEF-5 score and EHS score at 1, 3, 6 and 12 months after surgery, all these parameters were significantly improved compared with the preoperative, the differences were statistically significant ( P< 0.05). However, there was no significant difference between the two groups ( P> 0.05). There was no significant difference in IIEF-5 score and EHS score between the two groups during postoperative follow-up and before and after operation ( P> 0.05). The incidence of retrograde ejaculation rate in the improved group was lower than that in the conventional group during the follow-up 1, 3, 6 months after surgery, and the difference was statistically significant ( P<0.05). In the follow-up 1, 3 months after surgery, the incidence of stress urinary incontinence in the improved group was lower than that in the conventional group, the differences were statistically significant ( P< 0.05). At follow-up 6, 12 months after surgery, the rates of stress urinary incontinence were similar between the two groups, and the difference was not statistically significant ( P> 0.05). In the follow-up 12 months after surgery, there were 2 cases (3.33%) of bladder and neck contracture in the improved group, and 8 cases (13.33%) in the conventional group, the difference was statistically significant ( P<0.05). Conclusions:The effect of 980 nm semiconductor laser preablation of urethra mucosa at the prostatic tip in small volume BPH patients is similar to that of conventional vaporization, and the operation time is short. At the same time, the proximal 1 cm tissue of the verticulae and the integrity of the bladder neck are preserved, and the internal and external sphincter of the urethra are protected, thus improving the immediate postoperative urinary control rate and the incidence of retrograde ejaculation in small volume BPH patients.
