Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

1-Deoxy-D-xylulose-5-phosphate synthase (DXS), the first key enzyme in 2-methyl-D-erythritol-4-phosphate (MEP) pathway, catalyzes the condensation of glyceraldehyde-3-phosphate with pyruvate to 1-deoxy-xylose-5-phosphate (DXP). In this study, PgDXS1, PgDXS2, and PgDXS3 genes were cloned from the root of Platycodon grandiflorum (P. grandiflorum). The open reading frame (ORF) of PgDXS1, PgDXS2, and PgDXS3 were 2 160, 2 208, and 2 151 bp in full length, encoding 719, 735, and 716 amino acids, respectively. Homologous alignment results showed a high identity of PgDXSs with DXS in Hevea brasiliensis, Datura stramonium and Stevia rebaudiana. The recombinant expression plasmids of pET-28a-PgDXSs were constructed and transformed into Escherichia coli (E. coli) BL21 (DE3) cells, and the induced proteins were successfully expressed. Subcellular localization results showed that PgDXS1 and PgDXS2 were mainly located in chloroplasts, and PgDXS3 was located in chloroplasts, nucleus and cytoplasm. The expression of three DXS genes in different tissues of two producing areas of P. grandiflorum were assayed via real-time fluorescence quantitative PCR, and the results showed that all of them were highly expressed in leaves of P. grandiflorum from Taihe. Under methyl jasmonate (MeJA) treatment, the expression levels of three PgDXS genes showed a trend of first decreasing and then increasing at different time points (3 - 48 h), and the activity of DXS showed a trend of first increasing and then decreasing in three tissues of P. grandiflorum. This study provides a reference for further elucidating the biological function of PgDXS in terpenoid synthesis pathway in P. grandiflorum.

OBJECTIVE: To observe the clinical efficacy of acupoint injection combined with Vitalstim electrical stimulation for post-stroke dysphagia. METHODS: A total of 98 patients with dysphagia after first stroke were randomized into an acupoint injection group (35 cases, 2 cases dropped off), an electrical stimulation group (31 cases, 3 cases dropped off) and a combination group (32 cases, 3 cases dropped off). Injection of mecobalamin into Tunyan point, Vitalstim electrical stimulation and the combination of injection of mecobalamin into Tunyan point and Vitalstim electrical stimulation were applied respectively in the 3 groups, once a day, 10 times as one course, 2 courses were required. Before and after treatment, the tongue muscle thickness and video fluoroscopic swallowing study (VFSS) score were observed in the 3 groups. RESULTS: After treatment, the tongue muscle thickness was decreased (P<0.05), the VFSS scores were increased (P<0.05) compared with before treatment in the 3 groups, and the variation of tongue muscle thickness and VFSS score in the combination group was greater than the acupoint injection group and the electrical stimulation group (P<0.05). CONCLUSION Both acupoint injection of mecobalamin and Vitalstim electrical stimulation have therapeutic effect on dysphagia after stroke, and the two have synergistic effect.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

R2 R3-MYB transcription factors are ubiquitous in plants, playing a role in the regulation of plant growth, development, and secondary metabolism. In this paper, the R2 R3-MYB transcription factors were identified by bioinformatics analysis of the genomic data of Erigeron breviscapus, and their gene sequences, structures, physical and chemical properties were analyzed. The functions of R2 R3-MYB transcription factors were predicted by cluster analysis. Meanwhile, the expression patterns of R2 R3-MYB transcription factors in response to hormone treatments were analyzed. A total of 108 R2 R3-MYB transcription factors, named EbMYB1-EbMYB108, were identified from the genome of E. breviscapus. Most of the R2 R3-MYB genes carried 2-4 exons. The phylogenetic tree of MYBs in E. breviscapus and Arabidopsis thaliala was constructed, which classified 234 MYBs into 30 subfamilies. The MYBs in the five MYB subfamilies of A.thaliala were clustered into independent clades, and those in E. breviscapus were clustered into four clades. The transcriptome data showed that MYB genes were differentially expressed in different tissues of E. breviscapus and in response to the treatments with exogenous hormones such as ABA, SA, and GA for different time. The transcription of 13 R2 R3-MYB genes did not change significantly, and the expression patterns of some genes were up-regulated or down-regulated with the extension of hormone treatment time. This study provides a theoretical basis for revealing the mechanisms of R2 R3-MYB transcription factors in regulating the growth and development, stress(hormone) response, and active ingredient accumulation in E. breviscapus.

OBJECTIVES: To study the effect of glucose metabolism disorders on the short-term prognosis in neonates with asphyxia. METHODS: A retrospective analysis was performed on the medical data of the neonates with asphyxia who were admitted to 52 hospitals in Hubei Province of China from January to December, 2018 and had blood glucose data within 12 hours after birth. Their blood glucose data at 1, 2, 6, and 12 hours after birth (with an allowable time error of 0.5 hour) were recorded. According to the presence or absence of brain injury and/or death during hospitalization, the neonates were divided into a poor prognosis group with 693 neonates and a good prognosis group with 779 neonates. The two groups were compared in the incidence of glucose metabolism disorders within 12 hours after birth and short-term prognosis. RESULTS: Compared with the good prognosis group, the poor prognosis group had a significantly higher proportion of neonates from secondary hospitals (48.5% vs 42.6%, CONCLUSIONS Recurrent hyperglycemia in neonates with asphyxia may suggest poor short-term prognosis, and it is necessary to strengthen the early monitoring and management of the nervous system in such neonates.

Conclusion:Gegen Qinliantang repairs the intestinal mucosal barrier function by inhibiting the expressions of MMP-9 and inflammatory cytokines such as TNF-α and IL-1β， blocking the activation of the p38 MAPK signaling pathway， and increasing the expressions of tight junction protein.

Objective:To investigate the therapeutic effect of polydatin on ulcerative colitis （UC） in mice and its regulation of protein kinase Cθ（PKCθ）/signal transducer and activator of transcription 3（STAT3） signaling on T helper cell 17（Th17） and its mechanism in the treatment of UC. Method:The 32 male C57BL/6 mice were randomly divided into normal group， model group， polydatin group （0.045 g·kg^-1） and sulfasalazine group （0.5 g·kg^-1）. The UC model was established by giving 3% dextran sodium sulfate （DSS） solution to free drinking water in mice. Polydatin and sulfasalazine groups were given by gavage 0.5 h before modeling for 7 days. The normal group and model group were given the same amount of normal saline. After the last administration， the colonic tissue was taken and hematoxylin-eosin （HE） was used to observe the pathological changes of colonic tissue. Flow cytometry was used to detect the proportion of Th17 in the lamina propria of colonic mucosa. The expression of interleukin-17A （IL-17A） in serum was detected by enzyme-linked immunosorbent assay （ELISA）. Polydatin was added to CD4⁺ T cells purified from spleen of C57BL/6 mice by magnetic-activated cell sorting （MACS） under the stimulation of cell stimulation cocktail in vitro in order to detect its impact on PKCθ and STAT3 phosphorylation. Result:Compared with normal group， the body weight was significantly decreased， and disease activity index （DAI） scores of the model group was significantly increased （P<0.01）， the colonic mucosal epithelium was damaged and inflammatory cells infiltration in the mucosa and submucosa was obvious， the proportion of Th17 in the lamina propria of colonic mucosa was significantly increased （P<0.01）， and the content of serum IL-17A was significantly increased （P<0.01）. Compared with the model group， the weight and DAI score of polydatin and sulfasalazine groups were significantly improved （P<0.01）， the degree of colon tissue damage was significantly improved， the proportion of Th17 in colon mucosa lamina propria was significantly decreased （P<0.01）， and the content of IL-17A in serum was significantly decreased （P<0.01）. In vitro experiments showed that polydatin could significantly inhibit the phosphorylation of PKCθ and STAT3 in Th17 （P<0.01） as well as IL-17A secretion. Conclusion:Polydatin can improve the ulcerative colitis in mice via inhibiting the phosphorylation of PKCθ and STAT3 to preclude IL-17A secreting in Th17.
