ObjectiveStudies have shown that nuciferine has anti-cerebral ischemia effect， but the specific mechanism of action has not been elaborated. Based on the transcriptome results， the pharmacological mechanism of nuciferine against cerebral ischemia was analyzed from multiple dimensions including tissue， cell， pathological process， biological process and signaling pathway. MethodsThirty SD rats were randomly divided into the sham group， model group and nuciferine group（40 mg·kg^-1） according to weight. Except for the sham group， the model of middle cerebral artery occlusion（MCAO） was established by thread embolization method after 30 min of administration in the other two groups. Twenty-four hours after surgery， transcriptome sequencing was used to detect the gene expression profiles in the cortex penumbra of rat cerebral tissue， and gene ontology（GO） and kyoto encyclopedia of genes and genomes（KEGG） pathway enrichment analysis were performed for differentially expressed genes. The mechanismof nuciferine against cerebral ischemia was analyzed from 5 dimensions of tissue， cell， pathological process， biological process and signaling pathway by the transcriptome-based multi-scale network pharmacology platform（TMNP）. ResultsTranscriptome sequencing and gene quantitative analysis showed that 667 genes were significantly reversed by nuciferine. Further enrichment analysis of KEGG and GO suggested that the pathways of nuciferine involved regulating stress response， ion transport， cell proliferation and differentiation， and synaptic function. TMNP research found that at the tissue level， nuciferine could significantly improve the cerebral tissue injury caused by ischemia. At the cellular and pathological levels， nuciferine could play an anti-cerebral ischemia role by improving the state of various nerve cells， mobilizing immune cells， regulating inflammation. And at the level of biological processes and signaling pathways， nuciferine mainly acted on the processes such as vascular remodeling， inflammation-related signaling pathways， and synaptic signaling. ConclusionCombined with the results of transcriptome sequencing， gene quantitative analysis and TMNP， the mechanism of nuciferine against cerebral ischemia may be related to processes such as intervening in stress response and inflammation， affecting vascular remodeling and regulating synaptic function. These results can provide a basis and reference for further study of the pharmacological mechanism of nuciferine against cerebral ischemia.

Objective To investigate the efficacy of voriconazole in the treatment of pulmonary tuberculosis complicated with chronic pulmonary aspergillosis(CPA)based on CYP2C19 gene polymorphism detection and examine the factors affecting the efficacy for improving targeted therapy in clinical practice.Methods A total of 207 patients with pulmonary tuberculosis complicated with CPA treated in the Third People's Hospital of Kunming from December 2018 to November 2022 were randomly assigned to an observation group(105 cases)or a control group(102 cases).The patients in the control group received standard voriconazole treatment,while the patients in the observation group had their voriconazole regimen tailored based on CYP2C19 genotyping results.Plasma drug concentration levels,efficacy,and safety were compared between the two groups and in terms of CYP2C19 genotypes.Logistic regression analysis was used to identify the factors affecting treatment efficacy.Results The observation group showed significantly higher plasma voriconazole concentrations and overall antifungal efficacy compared to the control group(P＜0.05).In the observation group,CYP2C19 genotyping identified 37 extensive metabolizers(EM),47 intermediate metabolizers(IM),and 21 poor metabolizers(PM).Plasma concentration of voriconazole did not show significant difference between EM and IM(P＞0.05),but both PM and IM were associated with significantly lower plasma concentration of voriconazole than PM(P＜0.05).The clinical efficacy rate was 100％for PM,91.5％for IM,and 83.8％for EM(P＜0.05).The incidence of adverse events did not show significant difference among the three genotypes(P＞0.05).Logistic regression analysis revealed that lung cavitation,hypoalbuminemia,and agranulosis were significantly correlated with therapeutic efficacy(P＜0.05).Conclusions CYP2C19 gene polymorphism detection is valuable in clinical practice.It can inform anti-aspergillus therapy with voriconazole to effectively improve symptoms and clinical efficacy in patients with pulmonary tuberculosis complicated with CPA.Meanwhile,clinicians should be aware of the factors such as hypoproteinemia,agranulocytosis,and lung cavitation that may affect the efficacy of voriconazole.

N-glycosides comprise a broad range of compounds, some of which have demonstrated a variety of bioactivities, such as antiviral, antitumor, and antibacterial activities. Serving as essential building blocks for DNA and RNA, nucleosides are a particularly important subclass of N-glycosides. Accordingly, natural N-glycosides and their analogs have garnered great interests of both organic and pharmaceutical chemists, who have developed numerous synthetic methods for the preparation of N-glycosides. By reviewing the natural N-glycosides published between 1980 and 2023, this article summarizes current strategies for synthesizing N-glycosides, aiming to provide support for the development and research of N-glycosides.

Objective:To study the relation ship between the branch patterns of inferior mesenteric artery (IMA) and imaging pelvic measurement parameters for anastomotic leakage (AL) after anterior resection (AR) of rectal cancer.Methods:Five hundred thirty-four patient were enrolled from Jan 2008 to Dec 2018 at the General Surgery Department of Guizhou Provincial People's Hospital. The AL related imaging risk factors were analyzed by chi-square test or Fisher's exact test.Results:AL was found in 36 (6.7%) patients. AL related mortality rate was 11.1% (4/36) compared to 0.4% (2/498) in those without the complications of no AL cases ( P<0.001). Seven pelvic imaging measurement results were attained in 412 patients including anteroposterior diameter of the inlet of the pelvis, anteroposterior diameter of the outlet of the pelvis, upper edge of the symphysis pubis to the tip of the coccyx, sacrococcygeal distance angle from the lower edge of the pubis to the upper edge of the pubis to the sacral promontory, distance between the ischial spines and that of ischial tuberosity. Univariate analysis showed that there was no significant relationship between the above 7 pelvic measurement parameters and the occurrence of AL (all P>0.05). There was no significant relationship between branch patterns of IMA and AL after rectal cancer surgery ( P=0.712). Conclusion:AL as a severe postoperative complication in rectal cancer patients undergoing AR procedure were caused by multiple factors. Neither IMA branch patters nor pelvic imaging measurement seem to be related to the occurrence of AL after AR for rectal cancer.

Objective:To analyze the clinicopathological features and prognostic factors of alpha‐fetoprotein‐producing gastric carcinoma (AFPGC).Methods:A retrospective analysis was made on 2 671 GC patients admitted from Jan 1998 to Dec 2018 , AFPGC patients and matching AFP negative GC cases were enrolled and their clinicopathological features and prognostic factors were analyzed. The survival curve was drawn by Kaplan-Meier method. Log-rank test was used to test the significance, Univariate analysis was performed by using COX proportional hazard model.Results:There were 98 AFPGC in this study accounting for 4.5% of all GC of the corresponding time period. The proportion of male to female was 2.16∶1, the average age was (65±12) years. The serum AFP levels significantly decreased after operation in most patients (median: 52 ng/ml vs. 5 ng/ml, Ｚ=-2.736, P=0.001). Serum AFP and CEA levels in patients with AFPGC before treatment were significantly higher than that in patients with AFP negative GC (both P<0.05) . Vascular invasion(62.71% vs. 40.68%) and liver metastasis (31.63% vs .6.12%) were more likely to occur in AFPGC groups (both P<0.05). However, there was no significant difference between the two groups in tumor size, location, differentiation and lymph node metastasis (all P>0.05). The prognosis of AFPGC was significant pooer than that in AFP negative GC ( P<0.05). Prognosis of AFPGC patients was significantly correlated with preoperative serum AFP level, TNM stage, lymph node metastasis, simultaneous liver metastasis and vascular invasion (all P<0.05) . COX multivariate survival analysis found that preoperative serum AFP level was independent risk factors of patients with AFPGC ( P<0.05). Conclusion:AFPGC is a special GC charactering poor prognosis .

Objective:To evaluate the effect of Kinesio taping on knee osteoarthritis (KOA). Methods:The Cochrane Library, PubMed, CNKI, Web of Science and PEDro were searched from inception to November, 2018. The randomized controlled trials (RCTs) about the effect of Kinesio taping on knee osteoarthritis were collected. Two reviewers independently screened articles according to the inclusion and exclusion criteria, extracted data and evaluated the quality of the included studies. Meta-analysis was performed using RevMan 5.3. Results:A total of six RCTs were enrolled. There were significant differences in the scores of Visual Analogue Score between the intervention group and the control group (WMD = -1.28, 95%CI -2.36 to -0.20, P = 0.02). There were no significant differences in Western Ontario and McMaster Universities Osteoarthritis Index, range of motion, quadriceps femoris and hamstring muscle strength between the intervention group and the control group (P > 0.05). The other studies only adopted descriptive analysis accordingly. Conclusion:It is still uncertain in the effectiveness of Kinesio taping on knee osteoarthritis.
