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.

In this study, we employed a combination of genome mining and heteronuclear single quantum coherence (HSQC)-based small molecule accurate recognition technology (SMART) technology to search for fernane-type triterpenoids. Initially, potential endophytic fungi were identified through genome mining. Subsequently, fine fractions containing various fernane-type triterpenoids were selected using HSQC data collection and SMART prediction. These triterpenoids were then obtained through targeted isolation and identification. Finally, their antifungal activity was evaluated. As a result, three fernane-type triterpenoids, including two novel compounds, along with two new sesquiterpenes and four known compounds were isolated from one potential strain, Diaporthe discoidispora. Their structures were elucidated through analysis of high-resolution electrospray ionization mass spectrometry (HR-ESI-MS) and nuclear magnetic resonance (NMR) spectroscopic data. The absolute configurations were determined using single-crystal X-ray diffraction analysis and electron capture detector (ECD) analysis. Compound 3 exhibited moderate antifungal activity against Candida albicans CMCC 98001 and Aspergillus niger.

Occlusal rehabilitation is an effective means of treating tooth wear, edentulous jaws and other oral diseases. Among them, full-mouth fixed occlusal reconstruction can effectively restore aesthetics and function, but the complexity of the clinical process, the high sensitivity of the technique, and the high incidence of various complications have always drawn much attention. With the application and development of digital technology in occlusal rehabilitation, the treatment outcome has been improved compared with traditional treatment. However, there are many kinds of digital technology with different efficacy, how to build an efficiently standardized digital clinical technical solution is a current difficulty. Therefore, combined with the long-term work of the department of prosthodontics in our hospital, in this paper, the minimum (occlusal perception of thickness) and maximum (centric relation) geometric quantities which should be paid attention to during reconstruction are put forward. We systematically organized the clinical procedure of digital full-mouth fixed occlusal rehabilitation used in our department for a long time. In conclusion, a 5-stage 19-step or n-step solution (5-19N for short) characterized by "from large to small" restorative space splitting logic is proposed. It has a certain reference value for the future use of digital technology to deal with complex occlusal rehabilitation cases.

Objective: To investigate the protective effects of the combined concentrated liquid extract of Pueraria lobata (Willd.) Ohwi root (P. lobata, Ge Gen) and Hovenia dulcis Thunb. (H. dulcis, Zhi Ju Zi) against ethanol-induced liver damage in vitro, using a human hepatoma cell line G2 (HepG2) cell model. Methods: HepG2 cells were cultured in medium containing 4% ethanol to establish a model of alcoholic liver damage. The cells were then treated with the combined extract obtained via cryogenic extraction. Biochemical assays and Western blot analyses were performed to assess the levels of oxidative stress markers, antioxidant enzymes, and inflammatory cytokines. In addition, activation of the phosphoinositide 3-kinase/protein kinase B (PI3K/AKT) pathway was examined to elucidate the mechanisms underlying the effects of the extract. Results: Treatment with the extract contributed to a significant reduction in the release of nitric oxide and reactive oxygen species in the ethanol-treated HepG2 cells; promoted the elevated expression of superoxide dismutase, catalase, and glutathione, indicating enhanced antioxidant defenses; and showed strong free radical-scavenging activity against 1,1-diphenyl-2-picrylhydrazyl radicals. In addition, by activating the PI3K/AKT pathway, treatment promoted increases in the expression of nuclear factor erythroid 2-related factor 2 and its downstream targets, subsequently inhibiting apoptosis. Moreover. inflammatory responses were mitigated, as indicated by reductions in the expression of tumor necrosis factor-alpha and interleukin-6, and we detected reduction in the levels of alanine aminotransferase and aspartate aminotransferase, thereby indicating hepatoprotective effects. Conclusion The combined P. lobata root and H. dulcis extract was established to have notable antioxidative and anti-inflammatory properties, effectively alleviating ethanol-induced liver damage in vitro. These findings highlight the potential applicability of this extract as a candidate for treating alcoholic liver disease.

Objective:To explore the relationship between corrected serum calcium level and clinical characteristics in patients with newly-diagnosed multiple myeloma (MM), as well as the influencing factors of concomitant hypercalcemia.Methods:A retrospective case cohort study was conducted. The clinical data of newly-diagnosed MM patients who were admitted to Shanxi Province Cancer Hospital from January 2020 to December 2023 were collected. When serum albumin (ALB) was less than 40 g/L, the serum calcium level was corrected. The hypercalcemia group was defined as the corrected serum calcium level >2.60 mmol/L, the normal blood calcium group was defined as 2.20-2.60 mmol/L, and the hypocalcemia group was defined as <2.20 mmol/L; the combination of normal blood calcium group and hypocalcemia group was the non-hypercalcemia group. The age, gender, immune typing, ALB, blood urea nitrogen (BUN), serum creatinine (Scr), β 2-microglobulin (β 2-MG), and alkaline phosphatase (ALP) of patients in the hypercalcemia group and the non-hypercalcemia group were compared. Pearson correlation analysis was used for the correlation analysis. The logistic regression model was used to conduct multivariate analysis on the influencing factors of hypercalcemia. Results:Before correction, there were 31 cases (26.5%), 48 cases (40.0%) and 38 cases (32.5%) of MM patients in the hypocalcemia group, normal blood calcium group and hypercalcemia group, respectively. After correction, there were 17 cases (14.5%), 58 cases (49.6%) and 42 cases (35.9%), respectively. The corrected serum calcium level for male MM patients was (2.58± 0.41) mmol/L, while for females it was (2.53±0.38) mmol/L, and there was no statistically significant difference between the two groups ( t = 0.79, P > 0.05). The corrected serum calcium levels for patients in stage Ⅰ, stage Ⅱ and stage Ⅲ of the International Staging System (ISS) were (2.31±0.15) mmol/L, (2.52±0.37) mmol/L and (2.65±0.42) mmol/L, respectively, and the difference between the three groups was statistically significant ( F = 53.62, P < 0.01). Corrected serum calcium showed a negative correlation with patients' serum ALB ( r = -0.201, P < 0.05), and positive correlations with Scr, BUN and β 2-MG levels ( r values were 0.470, 0.247 and 0.469, respectively, all P < 0.01), but it had no correlation with age or ALP ( r values were -0.013 and 0.078, respectively, both P > 0.05). There were 15 cases (17.1%), 48 cases (54.5%) and 25 cases (28.4%) of patients with normal renal function in the hypocalcemia group, normal blood calcium group and hypercalcemia group, respectively; there were 2 cases (6.9%), 10 cases (34.5%) and 17 cases (58.6%) of patients with impaired renal function in the hypocalcemia group, normal blood calcium group and hypercalcemia group, respectively; there were statistically significant differences between the hypocalcemia group and the hypercalcemia group, as well as between the normal blood calcium group and the hypercalcemia group ( χ2 = 4.57, P < 0.05; χ2 = 6.67, P < 0.05), but there was no statistically significant difference between the hypocalcemia group and the normal calcium group ( χ2 = 0.29, P>0.05). The patients with approximately normal bone status in the hypocalcemia group, normal blood calcium group and hypercalcemia group were 3 cases (13.0%), 17 cases (74.0%) and 3 cases (13.0%), respectively, and the patients with bone damage were 14 cases (14.9%), 41 cases (43.6%), and 39 cases (41.5%), respectively, and there was a statistically significant difference between the normal blood calcium group and the hypercalcemia group ( χ2 = 7.48, P < 0.01), while there was no statistically significant difference between the hypocalcemia group and the hypercalcemia group ( χ2 = 1.46, P > 0.05). The proportions of patients with Scr > 177 μmol/L and β 2-MG > 3.5 mg/L in the hypercalcemia group were higher than those in the non-hypercalcemia group, and the differences were statistically significant (both P < 0.05). The results of logistic regression multivariate analysis showed that β 2-MG >3.5 mg/L was an independent risk factor for hypercalcemia in newly-diagnosed MM patients ( OR = 1.178, 95% CI: 1.058-1.311, P = 0.003). Conclusions:Corrected serum calcium level may be an important indicator for evaluating the severity of disease, renal function and bone status in newly-diagnosed MM patients.

Objective To investigate whether aberrant DNA methylation of ubiquinol-cytochrome C reductase core protein 1(UQCRC1)is related to cognitive impairment caused by neonatal sevoflurane exposure.Methods A total of 94 SPF C57 mice of either sex,aged 6 d,and weighing 4～6 g,were randomly divided into 7 groups:control group(Con,n=6),sevoflurane-6 and-24 h exposure groups(Sev-6 and-24 h,n=6),control+DMSO group(Con+DMSO,n=19),control+5-aza-2'-deoxycytidine(5-AZA,methylation inhibitor)group(Con+5-AZA,n=19),sevoflurane+DMSO group(Sev+DMSO group,n=19),and sevoflurane+5-AZA group(Sev+5-AZA group,n=19).From 6 to 8 d after birth,the mice of the Sev-6 and-24 h exposure groups were exposed to 3％sevoflurane daily(with 97％oxygen,2 L/min,2 h per day),while those from the Con groups were given exposure of 100％oxygen(2 L/min,2 h per day).For the mice of the 5-AZA and DMSO groups,1 mg/kg of 5-AZA or an equal volume of DMSO was injected intraperitoneally 30 min before daily exposure.In 6 and 24 h after the last exposure to sevoflurane,6 mice from the Con,Sev-6 h,and Sev-24 h groups were euthanized for biochemical analysis,and in 24 h post-exposure,6 mice from the Con+DMSO,Con+5-AZA,Sev+DMSO,and Sev+5-AZA groups were randomly selected for biochemical analysis,while another 3 mice from above each group were also randomly selected for morphological analysis.The remaining 10 mice in these groups underwent behavioral testing(open field test,novel object test,and Y-maze test)at 30～33 d after birth to assess cognitive function,and were euthanized in 24 h after the final behavioral test.RT-qPCR and Western blotting were used to detect the hippocampal expression of UQCRC1,DNA methyltransferases(Dnmts),and methyl CpG binding protein 2(Mecp2)at mRNA and protein levels,respectively.Immunofluorescence assay was employed to observe the distribution and expression of UQCRC1 in the hippocampus.Bisulfite sequencing PCR(BSP)was applied to measure the methylation in the UQCRC1 promoter region.Results Compared with the Con group,the mRNA and protein levels of UQCRC1 were down-regulated(P<0.05),and the mRNA level of Dnmts was up-regulated(P<0.05)in both the Sev-6 h and Sev-24 h exposure groups,while the methylation level in the UQCRC1 promoter region was enhanced in the Sev-24 h exposure group(P<0.05).Additionally,the Sev+5-AZA group had obviously increased mRNA and protein levels of UQCRC1(P<0.05),and notable improvement in cognitive impairment(P<0.05)when compared with the Sev+DMSO group.Conclusion Hypermethylation of UQCRC1 promoter region and thus down-regulating its mRNA and protein expression might be the main mechanism by which repeated neonatal sevoflurane exposure induces cognitive impairment later in life.

In this work,near infrared carbon quantum dots(NIR-CDs)were synthesized by hydrothermal method using biomass material Clausena lansium leaves.The synthesized NIR-CDs emitted maximum fluorescence signal at 677 nm,which was independent of excitation wavelength.The characterization results showed that there were abundant groups on the surface of NIR-CDs.Pd2+could form non-fluorescent compounds with the surface groups of NIR-CDs,resulting in fluorescence quenching(Fluorescence signal was denoted as F0).Because chlorpromazine hydrochloride(CPZ)parent nucleus contained unoxidized S atom,CPZ could form stable colored complex with Pd2+under acidic conditions.In the presence of CPZ,Pd2+dissociated from the surface of NIR-CDs and bonded with CPZ,so that the fluorescence signal could be restored(Fluorescence signal was denoted as F).An"on-off-on"fluorescence sensor was thus constructed.The fluorescence signal recovery value of NIR-CDs(△F=F-F0)showed a good linear relationship with the concentration of CPZ in the range of 5.68-28.43 μg/mL,and the detection limit(3σ)was 0.078 μg/mL.The sensor was applied to determination of CPZ in pharmaceutical preparations,and the recoveries were 94％-106％.The developed fluorescence sensor was expected to be used in quality control of actual pharmaceutical preparations.

Introducing fingerprint level 3 features(especially sweat pores)in fingerprint recognition can significantly improve the value of fingerprints.However,conventional fingerprint visualization methods suffer from issues such as poor stability and reproducibility,insufficient resolution,and feature masking in detecting level 3 features.Electrospun membrane has unique advantages in latent fingerprint(LFP)detection due to its excellent adsorption performance and high specific surface area,and thus its application potential in LFP visualization urgently need to be explored.A novel pore visualization method based on core-shell structured PAN-Flu/PVP composite nanofibrous membrane was proposed in this work.Specifically,the PAN-Flu/PVP composite nanofibrous membrane was prepared via coaxial electrospinning technology,with polyacrylonitrile(PAN)loaded with fluorescein(Flu)as the core and polyvinylpyrrolidone(PVP)as the shell.The experimental results showed that the prepared PAN Flu/PVP composite nanofibrous membrane had a porous structure and excellent adsorption performance.Based on the water solubility of the outer shell PVP and the water induced fluorescence enhancement effect of the core Flu,high-resolution visualization of sweat pores could be achieved within 2 s.The optimization experiment showed that the best quality of sweat latent fingerprints was obtained when the Flu content was 4 mg/mL,the spinning time was 1 h,and the sweating time was 2 min.Through repeated fingerprinting and live fingerprint comparison experiment,the strong stability and high reproducibility of the as-produced membrane in displaying fingerprint sweat pores were finally verified.In summary,the development method could quickly,stably and accurately extract the spatial distribution and activity level of fingerprint sweat pores,which was of great significance for improving the utilization and value of fingerprints.

Objective To investigate the effect and mechanism of WISP-1 on renal tubular epithelial cell fibrosis in rats with renal fibrosis.Methods Twenty-four adult rats and renal tubular epithelial cell line(NEK-52E)were se-lected for in vivo and in vitro experiments.The rats were randomly divided into control group and study group,and the in vivo renal fibrosis model was established.The expression of WISP-1 in the study group was blocked.The cell lines were induced to fibrosis followed by WISP-1 over-expression or inhibition.The related indicators of fibrosis were observed.Results Protein and mRNA level of Collagen Ⅰ(Col Ⅰ),fibronectin(FN),transforming growth factor-β1(TGF-β1)in WISP-1 over-expression group were all higher than those in control group.The protein and mRNA level of Col Ⅰ,FN and TGF-β1 in the WISP-1 inhibition group were lower than those in the control group(P＜0.05).WISP-1 blockade attenuated the pathological changes of renal fibrosis.The protein and mRNA levels of Col Ⅰ,FN,α-smooth muscle actin(α-SMA),TGF-β1,LC3 and Beclin-1 in the study group were lower than those in the control group,and the level of ubiquitin binding protein p62(SQSTM1/p62)was higher than that in the control group(P＜0.05).The expression of LC3 and Beclin-1 in WISP-1 inhibitor group was lower than that in the control group and the expression of SQSTM1/p62 was higher than that in the control group.The expression of LC3 and Beclin-1 in the WISP-1 over-expression group was higher than that in the control group,and the expres-sion of SQSTM1/p62 was lower than that in the control group.Conclusions Overexpression of WISP-1 promotes the fibrosis of rat renal tubular epithelial cells,and enhanced TGF-β1-mediated autophagy might be a underlying mechanism to mediate renal fibrosis.

The main features of chronic obstructive pulmonary disease include chronic airway inflammation,persis-tent airflow limitation,progressive dyspnea,and impaired lung function.Acetylation is one of the most common post-translational modifications of proteins,which plays an important role in the pathogenesis of chronic obstructive pulmonary disease,such as oxidative stress,inflammatory reaction,and airway remodeling,by regulating gene ex-pression,cell signaling,and protein function.Therefore,exploring the regulatory mechanism of acetylating modifi-cation in chronic obstructive pulmonary disease can not only deeply understand the pathophysiological mechanism of the disease,but also provide a theoretical basis for the development of new treatment strategies.
