ObjectiveBased on the conjoint analysis of transcriptome and metabolome, the key genes in the phenylpropanoid biosynthesis pathway of Lonicera macranthoides were explored, which provided a basis for further exploring the synthesis and regulation mechanism of phenylpropanoid compounds in "Xianglei" L. macranthoides. MethodsThe stem, leaves, and three flowering flowers of "Xianglei" L. macranthoides were selected as experimental materials to construct transcriptome and metabolome. The transcriptome and metabolomics were conjointly analyzed by the Kyoto Encyclopedia of Genes and Genomes (KEGG) database and weighted correlation network analysis (WGCNA), and the key genes in the phenylpropanoid biosynthesis pathway of L. macranthoides were explored. ResultsIn this study, 77 differential phenylpropanoids and 315 differential genes were found. Through the joint analysis of transcription and metabolism, nine key differential metabolites and four key genes related to them were finally discovered. Among them, cinnamic acid, 5-O-caffeoylshikimic acid,sinapyl alcohol, and chlorogenic acid were higher in flowers, and the content of the iconic effective component, namely chlorogenic acid,decreased sharply during the withering period. Caffeic acid,ferulic acid, 5-hydroxyconiferaldehyde,p-coumaryl alcohol, and syringin were higher in leaves. These four key genes belong to the cinnamic alcohol dehydrogenase (CAD) family, 4-coumaric acid: Coenzyme A (4CL) family, hydroxycinnamyl transferase (HCT) family, and L-phenylalanine ammonlyase (PAL) family genes. ConclusionAmong the four key genes excavated from L. macranthoides, TRINITY_DN42767_c0_g6 is related to the synthesis of p-coumaryl alcohol and sinapyl alcohol. TRINITY_DN43525_c4_g1 uses caffeic acid,ferulic acid,and cinnamic acid as substrates to catalyze the next reaction. TRINITY_DN47958_c3_g4 correlates with the synthesis of 3-p-coumaroyl quinic acid and caffeoyl-CoA, and TRINITY_DN52595_c1_g2 correlates with cinnamic acid synthesis. These findings provide a basis for further exploring the synthesis and regulation mechanism of phenylpropanoids in "Xianglei" L. macranthoides.

Objective:To investigate the clinical efficacy and safety of amlodipine besylate and benazepril hydrochloride tablets (II) in the treatment of primary hypertension.Methods:A total of 280 patients with primary hypertension who were treated at Shougang Shuigang Hospital between June 2022 and June 2023 were selected as study subjects. A clinical case-control study was conducted, and the RAND function method was utilized to randomly allocate the subjects into four groups, each receiving a different treatment: amlodipine besylate group (Group A, n = 70), benazepril hydrochloride group (Group B, n = 70), compound formulation amlodipine besylate and benazepril hydrochloride tablets group (Group C, n = 71), and amlodipine besylate plus benazepril hydrochloride group (Group D, n = 69). Relevant therapeutic indicators (blood pressure compliance rate, changes in blood pressure values) and safety indicators (adverse reactions, medication adherence) were observed. Results:The blood pressure compliance rates of Group C and Group D were 91.5% (65/71) and 89.9% (62/69), respectively. There was no statistically significant difference between the two groups ( χ2 = 1.24, P = 0.143), but both were higher than the rates of 77.1% (54/70) and 74.3% (52/70) in Group A and Group B, respectively ( χ2 = 5.68, 4.86, P = 0.004, 0.012). Before treatment, there was no statistically significant difference in systolic and diastolic blood pressure among the four groups of patients (all P > 0.05). After treatment, there was a statistically significant decrease in both systolic and diastolic blood pressure among the four groups compared with their pre-treatment levels (all P < 0.05). Specifically, Group C and Group D exhibited significant reductions in blood pressure following treatment ( t = 4.35, 5.12, 7.25, 5.86, all P < 0.05). Meanwhile, there was no statistically significant difference in systolic blood pressure between Group C and Group D after treatment ( P > 0.05), while diastolic blood pressure was lower in Group C than Group D after treatment ( t = 6.01, P < 0.05). There was a significant downward trend observed in total cholesterol, triglycerides, and low-density lipoprotein cholesterol levels (all P < 0.05). Notably, Group B and Group D reported higher incidences of dry cough, with 15 and 10 cases, respectively, compared with Group A and Group C, which had 1 and 3 cases, respectively. These differences were statistically significant ( χ2 = 4.25, 5.04, both P < 0.05). Furthermore, the treatment compliance rates for Group A, Group B, and Group C were 72.9% (51/70), 71.4% (50/70), and 74.6% (53/71), respectively, all exceeding the 46.4% (32/69) compliance rate of Group D. These differences were also statistically significant ( χ2 = 4.68, 5.24, 4.98, all P < 0.05). Conclusion:The clinical efficacy and safety of the compound formulation amlodipine besylate and benazepril hydrochloride tablets (II) in the treatment of primary hypertension are superior to those of single tablets and combination therapy.

Inhibiting the death receptor 3(DR3)signaling pathway in group 3 innate lymphoid cells(ILC3s)pre-sents a promising approach for promoting mucosal repair in individuals with ulcerative colitis(UC).Paeoniflorin,a prominent component of Paeonia lactiflora Pall.,has demonstrated the ability to restore barrier function in UC mice,but the precise mechanism remains unclear.In this study,we aimed to delve into whether paeoniflorin may promote intestinal mucosal repair in chronic colitis by inhibiting DR3 signaling in ILC3s.C57BL/6 mice were subjected to random allocation into 7 distinct groups,namely the control group,the 2%dextran sodium sulfate(DSS)group,the paeoniflorin groups(25,50,and 100 mg/kg),the anti-tumor necrosis factor-like ligand 1A(anti-TL1A)antibody group,and the IgG group.We detected the expression of DR3 signaling pathway proteins and the proportion of ILC3s in the mouse colon using Western blot and flow cytometry,respectively.Meanwhile,DR3-overexpressing MNK-3 cells and 2% DSS-induced Rag1-/-mice were used for verification.The results showed that paeoniflorin alleviated DSS-induced chronic colitis and repaired the intestinal mucosal barrier.Simultaneously,paeoniflorin inhibited the DR3 signaling pathway in ILC3s and regulated the content of cytokines(interleukin-17A,granulocyte-macrophage colony stimulating factor,and interleukin-22).Alternatively,paeoniflorin directly inhibited the DR3 signaling pathway in ILC3s to repair mucosal damage indepen-dently of the adaptive immune system.We additionally confirmed that paeoniflorin-conditioned me-dium(CM)restored the expression of tight junctions in Caco-2 cells via coculture.In conclusion,paeoniflorin ameliorates chronic colitis by enhancing the intestinal barrier in an ILC3-dependent manner,and its mechanism is associated with the inhibition of the DR3 signaling pathway.

Third-degree atrioventricular block is a severe bradyarrhythmia, for which there is no proven effective drugs currently. Permanent pacemaker implantation recommended by the guideline, however, is not suitable for most patients. This paper reported on a case of third-degree atrioventricular block after cardiac radiofrequency ablation who has been treated with the method of boosting qi, warming yang and unblocking collaterals. The TCM syndrome of this case was diagnosed as yang qi depletion and phlegm-stasis blocking the collaterals, for which Baoyuan Decoction and Mahuang Fuzi Xixin Decoction (保元汤合麻黄附子细辛汤) in modification has been used to boost qi, warm yang and raise the sunken, dissolve phlegm, invigorate blood and unblock collaterals. After nearly 7-month treatment, the symptoms such as palpitations, shortness of breath and fatigue were basically cured, and the electrocardiogram returned to the normal.

Objective:To explore the risk factors of bortezomib-related peripheral neuropathy (BIPN) and the clinical and electrophysiological characteristics of patients in treatment of multiple myeloma (MM).Methods:The clinical data of 71 newly diagnosed MM patients treated with BD (bortezomib + dexamethasone) regimen in Yancheng First People's Hospital from March 2016 to December 2019 were retrospectively analyzed. The bone marrow morphology, immunology, cytogenetics, molecular biology (MICM), routine electrophysiological examination before and after treatment were performed. All patients were divided into the peripheral neuropathy (PN) group and the non-PN group according to the presence or not of BIPN, and the clinicopathological differences of both groups were also compared; a binary logistic regression model was used to analyze the factors affecting the occurrence of PN. The electrophysiological characteristics were summarized and fluorescence in situ hybridization (FISH) was used to detect karyotype of BIPN patients.Results:Among 71 MM patients, there were 40 cases (56.3%) of PN and 31 cases (43.7%) of non-PN. The proportion of patients at international staging system (ISS) staging Ⅲ, and the levels of IgA, IgG, IgM, serum creatinine, β 2-microglobulin (β 2-MG) in the PN group were higher than those in the non-PN group, and hemoglobin (Hb) level in the PN group was lower than that in the non-PN group, and the differences were statistically significant (both P < 0.05). Binary logistic regression analysis showed that increased IgA ( OR = 1.151, 95% CI 1.012-1.309, P = 0.033), increased IgG ( OR = 1.055, 95% CI 1.000~1.112, P = 0.049), increased IgM ( OR = 1.010, 95% CI 1.001-1.018, P = 0.022), increased serum creatinine ( OR = 1.037, 95% CI 1.011~1.065, P = 0.005), increased β 2-MG ( OR = 1.564, 95% CI 1.039-2.354, P = 0.032) were risk factors for BIPN. Among 40 patients with BIPN, 33 cases (82.5%) of sensory nerve conduction velocity (SCV) were abnormal, 23 cases (57.5%) of motor nerve conduction velocity (MCV) were abnormal; 31 cases (77.5%) showed demyelination damage, 9 cases (22.5%) had axonal damage. Among 40 patients with BIPN, 24 cases underwent FISH detection, including 19 cases (79.2%) with chromosomal mutations, of which 12 cases (50.0%) were mixed subtype abnormal. Conclusions:MM patients with high levels of β 2-MG, IgA, IgG, IgM and serum creatinine are more prone to PN when treated with bortezomib. The electrophysiology of patients with BIPN is mainly characterized by demyelination of sensory nerves.
