ObjectiveTo establish a model that can quickly identify the aroma components in different parts of Nardostachys jatamansi, so as to provide a quality control basis for the market circulation and clinical use of N. jatamansi. MethodsHeadspace solid-phase microextraction-gas chromatography-mass spectrometry(HS-SPME-GC-MS) combined with Smart aroma database and National Institute of Standards and Technology(NIST) database were used to characterize the aroma components in different parts of N. jatamansi, and the aroma components were quantified according to relative response factor(RRF) and three internal standards, and the markers of aroma differences in different parts of N. jatamansi were identified by orthogonal partial least squares-discriminant analysis(OPLS-DA) and cluster thermal analysis based on variable importance in the projection(VIP) value >1 and P<0.01. The odor data of different parts of N. jatamansi were collected by Heracles Ⅱ Neo ultra-fast gas phase electronic nose, and the correlation between compound types of aroma components collected by the ultra-fast gas phase electronic nose and the detection results of HS-SPME-GC-MS was investigated by drawing odor fingerprints and odor response radargrams. Chromatographic peak information with distinguishing ability≥0.700 and peak area≥200 was selected as sensor data, and the rapid identification model of different parts of N. jatamansi was established by principal component analysis(PCA), discriminant factor alysis(DFA), soft independent modeling of class analogies(SIMCA) and statistical quality control analysis(SQCA). ResultsThe HS-SPME-GC-MS results showed that there were 28 common components in the underground and aboveground parts of N. jatamansi, of which 22 could be quantified and 12 significantly different components were screened out. Among these 12 components, the contents of five components(ethyl isovalerate, 2-pentylfuran, benzyl alcohol, nonanal and glacial acetic acid,) in the aboveground part of N. jatamansi were significantly higher than those in the underground part(P<0.01), the contents of β-ionone, patchouli alcohol, α-caryophyllene, linalyl butyrate, valencene, 1,8-cineole and p-cymene in the underground part of N. jatamansi were significantly higher than those in the aboveground part(P<0.01). Heracles Ⅱ Neo electronic nose results showed that the PCA discrimination index of the underground and aboveground parts of N. jatamansi was 82, and the contribution rates of the principal component factors were 99.94% and 99.89% when 2 and 3 principal components were extracted, respectively. The contribution rate of the discriminant factor 1 of the DFA model constructed on the basis of PCA was 100%, the validation score of the SIMCA model for discrimination of the two parts was 99, and SQCA could clearly distinguish different parts of N. jatamansi. ConclusionHS-SPME-GC-MS can clarify the differential markers of underground and aboveground parts of N. jatamansi. The four analytical models provided by Heracles Ⅱ Neo electronic nose(PCA, DFA, SIMCA and SQCA) can realize the rapid identification of different parts of N. jatamansi. Combining the two results, it is speculated that terpenes and carboxylic acids may be the main factors contributing to the difference in aroma between the underground and aboveground parts of N. jatamansi.

ObjectiveTo explore the clinical effectivess of Nuangong Tiaojing Decoction (暖宫调经汤) combined with ginger moxibustion at Baliao acupoints (Eight Bone-Holes) for treating premature ovarian failure (POF) of yang-deficiency uterus-coldeness syndrome, based on conventional western medical treatment. MethodsA total of 130 patients diagnosed with POF of yang-deficiency uterus-coldeness syndrome were divided into a treatment group and a control group, with 65 cases in each group, based on patient preference. The control group received conventional western medicine treatment, while the treatment group was additionally given Nuangong Tiaojing Decoction orally one dose per day and underwent ginger moxibustion at Baliao points once daily. Both groups were treated for three months. Before and after treatment, ovarian function indicators, including ovarian volume, follicle count, ovarian peak systolic velocity (PSV), and endometrial thickness were assessed, and serum sex hormone levels including progesterone (P), estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), and testosterone (T), as well as anti-Müllerian hormone (AMH) levels were also measured. Additionally, traditional Chinese medicine (TCM) syndrome scores were evaluated, covering symptoms such as reduced libido, lumbosacral pain, fear of cold with cold extremities, fatigue, dull complexion, lower abdominal distension and pain, pale tongue, and deep and rough pulse. After treatment, clinical effectiveness and safety were determined. ResultsCompared with the pre-treatment levels within group, both groups showed significant increases in ovarian volume, follicle count, PSV, endometrial thickness, and levels of P, E2, and AMH after treatment, while the levels of FSH, LH, PRL, and T, as well as scores of lumbosacral pain, reduced libido, dull complexion, deep and rough pulse, and total TCM syndrome scores significantly reduced after treatment. Furthermore, the treatment group exhibited higher ovarian volume, follicle count, PSV, endometrial thickness, and levels of P, E2, and AMH compared to the control group, while FSH, LH, PRL, T levels, and all symptom scores, as well as total TCM syndrome scores, were significantly lower in the treatment group than in the control group (P<0.05 or P<0.01). The clinical effectiveness in treatment group was 96.92% (63/65), significantly higher than 81.54% (53/65) in control group (P<0.05). The incidence of adverse reactions in the treatment group was 26.15% (17/65), while in the control group it was 32.31% (21/65), with no statistically significant difference (P>0.05). ConclusionOn the basis of conventional western medicine treament, Nuangong Tiaojing Decoction combined with ginger moxibustion at Baliao acupoints for patients with POF of yang-deficiency uterus-coldeness syndrome can significantly improve ovarian function and clinical symptoms, regulate hormone levels, and thereby enhance clinical effectiveness.

With the rapid development of sequencing technologies, the detection of alternative polyadenylation (APA) in mammals has become more precise. APA precisely regulates gene expression by altering the length and position of the poly(A) tail, and is involved in various biological processes such as disease occurrence and embryonic development. The research on APA in mammals mainly focuses on the following aspects:(1) identifying APA based on transcriptome data and elucidating their characteristics; (2) investigating the relationship between APA and gene expression regulation to reveal its important role in life regulation;(3) exploring the intrinsic connections between APA and disease occurrence, embryonic development, differentiation, and other life processes to provide new perspectives and methods for disease diagnosis and treatment, as well as uncovering embryonic development regulatory mechanisms. In this review, the classification, mechanisms and functions of APA were elaborated in detail and the methods for APA identifying and APA data resources based on various transcriptome data were systematically summarized. Moreover, we epitomized and provided an outlook on research on APA, emphasizing the role of sequencing technologies in driving studies on APA in mammals. In the future, with the further development of sequencing technology, the regulatory mechanisms of APA in mammals will become clearer.

With the widespread adoption of low-dose CT screening and the extensive application of high-resolution CT, the detection rate of sub-centimeter lung nodules has significantly increased. How to scientifically manage these nodules while avoiding overtreatment and diagnostic delays has become an important clinical issue. Among them, lung nodules with a consolidation tumor ratio less than 0.25, dominated by ground-glass shadows, are particularly worthy of attention. The therapeutic challenge for this group is how to achieve precise and complete resection of nodules during surgery while maximizing the preservation of the patient's lung function. The "watershed topography map" is a new technology based on big data and artificial intelligence algorithms. This method uses Dicom data from conventional dose CT scans, combined with microscopic (22-24 levels) capillary network anatomical watershed features, to generate high-precision simulated natural segmentation planes of lung sub-segments through specific textures and forms. This technology forms fluorescent watershed boundaries on the lung surface, which highly fit the actual lung anatomical structure. By analyzing the adjacent relationship between the nodule and the watershed boundary, real-time, visually accurate positioning of the nodule can be achieved. This innovative technology provides a new solution for the intraoperative positioning and resection of lung nodules. This consensus was led by four major domestic societies, jointly with expert teams in related fields, oriented to clinical practical needs, referring to domestic and foreign guidelines and consensus, and finally formed after multiple rounds of consultation, discussion, and voting. The main content covers the theoretical basis of the "watershed topography map" technology, indications, operation procedures, surgical planning details, and postoperative evaluation standards, aiming to provide scientific guidance and exploration directions for clinical peers who are currently or plan to carry out lung nodule resection using the fluorescent microscope watershed analysis method.

Objective To investigate the discovery and disposal process and epidemiological characteristics of the first confirmed case of mpox (formerly named monkeypox) in Huai'an, Jiangsu Province, and to provide reference for the prevention and control of key infectious diseases in this region. Methods The on-site epidemiological investigation data of the first confirmed case of mpox on June 21, 2023, as well as the results of nucleic acid detection and gene sequencing of laboratory specimens were analyzed retrospectively. Possible sources of infection were explored. Results The first confirmed case of mpox was an AIDS patient, men who had sex with men (MSM), who had no history of travel abroad or outside the city within 21 days before the onset of the disease, but had interacted with some people outside the city, and the epidemiological trajectory was complex. The detection of mpox virus nucleic acid was positive (BioGerm reagent: Ct value 21.8, ZhuoCheng reagent: Ct value 21.2). According to genetic sequencing, the first confirmed case was classified as C.1.1 lineage of clade IIb. During the investigation on the source of infection of the first confirmed case, one new asymptomatic infected person was found. Based on the epidemiological investigation and laboratory results, the first confirmed case was believed to be caused by local infection, however, the source of infection was unclear. Although there was an epidemiological association with asymptomatic infected people, the direct evidence of mutual infection was insufficient, and it could not be ruled out that there was still a hidden transmission chain between regions. The source of infection of the asymptomatic infected person was presumed to be the first confirmed case or an unidentified person with whom he had high-risk sex and caused anal bleeding. Conclusion The first confirmed case is caused by local infection. Awareness of case diagnosis and reporting in medical institutions should be improved, and publicity and education should be provided to key exposed populations, especially those men who have sex with men, to prevent the occurrence of large-scale local epidemic.

Stroke is the main cause of death and disability among adults in China and is characterized by high incidence, disability, mortality, and recurrence rates. The combination of traditional Chinese and Western medicine has great potential in treating stroke and its sequelae. The classic traditional Chinese medicine prescription Da Chengqitang (DCQT) has a long history and proven efficacy in treating stroke. Clinically, DCQT is often used to treat stroke and its sequelae. However, the number and quality of clinical trials of DCQT in treating stroke need to be improved. Because of the insufficient basic research, the active ingredients and multi-target mechanism of action of DCQT remain unclear. Our research group has previously confirmed that DCQT can effectively reverse neurological damage, reduce iron deposition, and downregulate the levels of pro-inflammatory cytokines in the rat model of hemorrhagic stroke. The treatment mechanism is related to the nuclear factor erythroid 2-related factor 2 (Nrf2)-mediated signaling pathway and p38 mitogen-activated protein kinase (MAPK) signaling-mediated microglia activation. To clarify the pharmacodynamic basis and anti-stroke mechanism of DCQT, this article reviews the research progress in the treatment of stroke with DCQT in terms of clinical trials, pharmacodynamic material basis, safety evaluation, and mechanisms of absorbed components. This article summarizes 45 major phytochemical components of DCQT, 11 of which are currently confirmed absorbed components. Among them, emodin, rhein, chrysophanol, aloe-emodin, synephrine, hesperidin, naringin, magnolol, and honokiol can be used as quality markers (Q-markers) of DCQT. The mechanism of DCQT in treating stroke is complex, involving regulation of inflammatory responses, neuronal damage, oxidative stress, blood-brain barrier, brain-derived neurotrophic factor, and anti-platelet aggregation. This article helps to deeply understand the pharmacodynamic basis and mechanism of DCQT in treating stroke and provides a theoretical basis for the clinical application of DCQT in treating stroke and the development of stroke drugs.

Objective To analyze the virus subtypes, molecular evolutional and molecular transmission network features of the first confirmed mpox case in Huai’an City, Jiangsu Province, so as to provide insights into understanding of the transmission and evolution dynamics of mpox virus and formulation of the mpox control strategy in the city. Methods Genomic DNA was extracted from swabs of the first confirmed mpox case’s skin lesions in Huai’an City, and the amplicon sequencing library was constructed using the hypersensitive mpox virus whole-genome capture kit. High-throughput sequencing was performed using the GridION X5 nanopore sequencer on the Nanopore sequencing platform, and single nucleotide polymorphism (SNP) analysis of mpox virus genome sequences was performed following sequence assembly. In addition, phylogenetic analysis, genetic genealogy and molecular traceability analysis were performed. Results The virus whole genome sequence of the first confirmed mpox case was successfully obtained by high-throughput sequencing, with a full length of 197 182 bp, and was named hMpxV/China/JS-HA01/2023, which belonged to the clade IIb (West African clade) lineage B.1.3. Compared with the mpox virus reference sequence MPXV-M5312_HM12_Rivers-001 (GenBank accession number: NC_063383), the genome sequence of the Huai’an virus isolate carried 86 SNPs, including 40 SNPs in the coding region as non-synonymous mutations and 73 SNPs as nucleotide mutations caused by APOBEC3 (APOBEC3). Of the 97 mpox virus gene sequences, 79 sequences were included in the molecular network (81.44%), and the threshold of the genetic distance accessed to the network was 0.35/105. There were two large molecular transmission clusters and one scattered cluster in the molecular transmission network of the mpox virus, andthehMpxV/China/JS-HA01/2023 sequence was located in the large cluster. The 97 gene sequences formed 92 haplotypes, including three shared haplotypes Hap_4, Hap_6 and Hap_38, and an exclusive haplotype Hap_1 of hMpxV/China/JS-HA01/2023 generated from mutation of the exclusive haplotype Hap_43, while the exclusive haplotype Hap_43 was generated from mutation of the shared haplotype Hap_38. Conclusions The whole genome sequence of the mpox virus isolated from the first confirmed mpox case in Huai’an City has been successfully obtained, and the molecular evolutionary and molecular transmission network characteristics of the virus have been preliminarily understood.

BACKGROUND:Multiple studies have confirmed that mitogen-activated protein kinase(MAPK)signaling pathway is involved in cell proliferation,and microRNA(miR)is involved in the occurrence and development of hypertrophic scars.Therefore,the role of miR-27a-3p and MAPK signaling pathways in pathological scar formation has been further explored. OBJECTIVE:To explore the effect of miR-27a-3p on the proliferation of human hypertrophic scar fibroblasts through the MAPK signaling pathway. METHODS:The primary fibroblasts were isolated and collected from the skin samples.The primary fibroblasts were observed by inverted microscope and verified by immunofluorescence.The relative expression level of miR-27a-3p in tissues was detected by qRT-PCR.The target genes of hsa-miR-27a-3p were predicted using the database,and then the predicted target genes were enriched by gene ontology function analysis and biological pathway enrichment analysis of the Kyoto Encyclopedia of Genes and Genomes.There were seven groups:blank control,negative control,miR-27a-3p mimic,miR-27a-3p inhibitor,miR-27a-3p mimic+p38 MAPK inhibitor,miR-27a-3p mimic+extracellular regulated protein kinase inhibitor,miR-27a-3p mimic+c-Jun N-terminal kinase inhibitor.Western blot was used to detect the levels of extracellular regulated protein kinase,c-Jun N-terminal kinase inhibitor.and p38 kinase and their phosphorylation levels.Cell counting kit-8 and EdU were used to detect cell proliferation. RESULTS AND CONCLUSION:Compared with normal skin fibroblasts,hypertrophic scar fibroblasts had stronger proliferative activity(P<0.05)and faster proliferation level(P<0.001).Compared with normal skin,miR-27a-3p was highly expressed in hypertrophic scars(P<0.001).Compared with the negative control group,overexpression of miR-27a-3p could promote cell proliferation activity(P<0.001)and proliferation levels(P<0.001).Compared with the negative control group,knockdown of miR-27a-3p could inhibit the proliferation activity(P<0.05)and proliferation levels(P<0.001).Compared with the negative control group,overexpression of miR-27a-3p promoted the phosphorylated levels of extracellular regulated protein kinase,c-Jun N-terminal kinase,and p38 mitogen-activated protein kinase(P<0.05).Compared with the negative control group,knockdown of miR-27a-3p inhibited the phosphorylated levels of extracellular regulated protein kinase,c-Jun N-terminal kinase,and p38 MAPK(P<0.05).Compared with the miR-27a-3p mimic group,specific inhibitors of extracellular regulated protein kinase,c-Jun N-terminal kinase,and p38 MAPK reversed the effects of miR-27a-3p on the proliferative activity(P<0.01)and proliferation level(P<0.001)of fibroblasts.To conclude,these results suggest that miR-27a-3p promotes the proliferation of human hypertrophic scar fibroblasts by activating the MAPK signaling pathway.
