Chaihu Guizhi Ganjiangtang was first recorded in the Treatise on Cold Damage （Shang Han Lun）. This prescription is composed of Bupleuri Radix， Scutellariae Radix， Cinnamomi Ramulus， Zingiberis Rhizoma， Trichosanthis Radix， Ostreae Concha， and Glycyrrhizae Radix et Rhizoma. It has the effects of soothing Lesser Yang， warming the spleen， and stimulating the generation of body fluid. It is mainly used to treat digestive tract diseases such as chronic cholecystitis （CC）， irritable bowel syndrome， and non-alcoholic fatty liver disease. Dyspepsia caused by CC presents a variety of gastrointestinal symptoms such as abdominal pain， poor appetite， postprandial fullness， aversion to greasy food， soft stool， and bitter mouth， being a type of biliary dyspepsia. In modern medicine， dyspepsia caused by CC is mainly managed by medical treatment and surgical treatment. Internal medicine mainly focuses on reducing inflammation， promoting the function of gallbladder， resolving stones， alleviating spasms， and relieving the pain for CC， demonstrating definite short-term efficacy but suffering from single effects， high recurrence rate， and poor compliance. Although surgical treatment can cure cholecystitis， it is accompanied by the increased incidence of adverse events such as abdominal pain， diarrhea， and dyspepsia. Modern clinical studies have confirmed that Chaihu Guizhi Ganjiangtang can significantly alleviate the symptoms such as abdominal pain and dyspepsia of CC patients. Pharmacological studies have found that Chaihu Guizhi Ganjiangtang mainly contains active ingredients such as Bupleuri Radix saponins， baicalin， cinnamaldehyde， gingerol， Trichosanthis Radix polysaccharide， Ostreae Concha polysaccharide， and Glycyrrhizae Radix et Rhizoma total flavonoids. Chaihu Guizhi Ganjiangtang can ameliorate the symptoms of dyspepsia caused by CC by inhibiting inflammatory responses， improving gallbladder contraction and gastrointestinal motility， regulating the bile acid-intestinal flora axis and the brain-gut axis， and modulating blood lipids through multiple targets. By reviewing the previous literature， this article summarizes the research progress in the treatment of dyspepsia caused by CC with Chaihu Guizhi Ganjiangtang and its main active ingredients as well as the pathogenesis of this disease and puts forward the shortcomings and improvement strategies for the current research. The review aims to provide a reference for the further research on Chaihu Guizhi Ganjiangtang in the treatment of dyspepsia caused by CC.

OBJECTIVE To develope a predictive model for medication deviation risks during the hospital-to-home transition period in coronary heart disease （CHD） patients with initial treatment， aiming to assist medical staff in rapidly identifying high-risk groups for medication deviation. METHODS A total of 462 CHD patients with initial treatment from the Affiliated Hospital of North China University of Science and Technology （hereinafter referred to as “our hospital”） between January and July 2024 were enrolled. The patients were randomly divided into a modeling group and an internal validation group. The modeling group was further categorized into a medication deviation group and a non-medication deviation group based on whether medication deviations occurred. Similarly， 57 CHD patients with initial treatment from the cardiology department of our hospital between June and September 2025 were collected as an external validation group. Univariate analysis was used to screen predictive factors， followed by multivariate Logistic regression to construct the predictive model. Internal validation methods were employed to evaluate model performance， while external validation methods were used to test the model’s generalizability. RESULTS The 462 patients were divided into a modeling group （319 cases） and an internal validation group （143 cases）. In the modeling group， the medication deviation group （192 cases， 60.19%） and the non-medication deviation group （127 cases， 39.81%） were identified. Multivariate Logistic regression analysis revealed that age， medication type， medication adherence， and self-efficacy in rational medication use were predictive factors for medication deviations in CHD patients with initial treatment （ P ＜0.05）. The predictive model equation was logit P ＝ln[ P /（1－ P ） ] ＝1.321+1.732×age+4.091×medication type －4.360×medication adherence －3.081×self-efficacy in rational medication use. The model demonstrated good discrimination， with a Hosmer-Lemeshow goodness-of-fit test P -value of 0.439， an area under the receiver operating characteristic curve （AUC） of 0.870， sensitivity of 0.970， and specificity of 0.607. A risk nomogram with a total score of 350 points and a cutoff value of 110 points was plotted. The internal validation group showed an AUC o f 0.787 and a prediction accuracy of 77.6%， while the external validation group exhibited an AUC of 0.802 and a prediction accuracy of 73.7%. CONCLUSIONS This study successfully developed a predictive model for medication deviation risks during the hospital-to-home transition period in CHD patients with initial treatment. The model demonstrates excellent discrimination and predictive accuracy， effectively identifying high-risk populations for medication deviations. Age （＞70 years）， number of drug types≥5， poor medication adherence， and poor self-efficacy in rational medication use are independent risk factors for medication deviations.

OBJECTIVE: To investigate the detection patterns, clinical phenotypic characteristics, and differences in diagnostic timeliness of Klinefelter syndrome (KS) across prenatal and postnatal stages, with an aim to provide a basis for optimizing strategies for early screening, diagnosis, and intervention. METHODS: A retrospective study was conducted to analyze data from two phases. The prenatal diagnosis group included 33,302 pregnant women who underwent amniocytic karyotyping due to advanced maternal age, abnormal ultrasound findings, or high-risk non-invasive prenatal testing (NIPT). The postnatal diagnosis group included 52,101 patients who underwent peripheral blood karyotyping due to primary infertility, abnormal external genitalia, or growth and developmental abnormalities. Additionally, medical histories of adult diagnosed patients were reviewed retrospectively to identify early occult symptoms. This study was approved by the Medical Ethics Committee of Chengdu Women's and Children's Central Hospital (Ethics No.: LCYJ-2025-030). RESULTS: In the prenatal group, 96 cases of KS were detected (detection rate 0.29%). The primary indications for referral were NIPT indicating sex chromosome abnormalities (45.83%), advanced maternal age (16.66%), and ultrasound abnormalities (17.70%). In the postnatal group, 128 cases of KS were detected (detection rate 0.25%). Clinical presentations were primarily primary infertility/azoospermia (77.34%), and the patients were predominantly adults (84.40%). Retrospective analysis revealed that adult patients presented with specific physical signs that had been overlooked during childhood. CONCLUSION As KS lacks typical early clinical manifestations, diagnosis is often delayed until adulthood when reproductive needs arise, showing a pattern of "passive detection" and resulting in missed opportunities for optimal intervention. By conducting a comparative analysis of prenatal diagnostic data and postnatal retrospective data, a risk association model linking prenatal screening indications with childhood-specific signs was developed. This study has provided empirical evidence for establishing a multidisciplinary, full life-cycle management system of "screening ~ diagnosis ~ monitoring ~ intervention" helping to shift from "passive detection in adulthood" to "proactive management across the entire life course," and laid a foundation for improving early diagnosis rate and long-term quality of life for patients.

ObjectiveTo analyze the epidemiological and etiological characteristics of a cluster of human metapneumovirus (HMPV) infection in a kindergarten in Gongshu District of Hangzhou City in May 2024, and to provide reference for the prevention and control of similar outbreaks. MethodsAn on-site investigation was conducted using an epidemiological case investigation form. Throat swab specimens collected from cases were screened for 13 respiratory pathogens using real-time fluorescent polymerase chain reaction (PCR). For HMPV nucleic acid positive specimens, the F gene of HMPV was used as the target gene for amplification and sequencing. The sequencing results were then compared with sequences in GenBank database to determine the virus subtypes and perform phylogenetic analyses. ResultsThe outbreak occurred in a kindergarter junior class with a total of 28 preschoolers and 3 teachers and childcare workers. A total of 11 cases (10 preschoolers and 1 teacher) were identified, including 8 male cases and 3 female cases. Clinical manifestations included fever in all 11 cases (100.00%), cough in 8 cases (72.72%), catarrhal symptoms in 4 cases (36.36%), and headache in 3 cases (27.27%). All symptoms were mild, and no severe cases were observed. A total of 11 throat swab samples were collected. Real-time fluorescent PCR test results showed that 3 samples were positive for HMPV nucleic acid, 2 samples were positive for both HMPV and Streptococcus pneumoniae, and 1 sample was positive for both HMPV and rhinovirus. The sequences of the 6 HMPV nucleic acid positive specimens were amplified and analyzed using specific primers, and all were determined to be HMPV subtype A2b. The F gene fragment sequence showed the highest similarity to PV081665.1/Brazil/2024 (99.65%), and also exhibited high similarity to PP683455.1/Indonesia/2021 (99.48%), PV016275.1/Beijing/2024 (99.31%), and PV052230.1/USA/2024 (99.13%). ConclusionThis cluster of acute respiratory tract infection was caused by HMPV subtype A2b, with co-infection of rhinovirus and Streptococcus pneumoniae. The F gene fragment sequences of the HMPV in this outbreak were highly homologous to those of the A2b strains isolated from Brazil, Beijing, Indonesia, and the the United States.

Objective To assess the potential role of disulfidptosis-related genes (DRGs) in pan-cancer on prognosis and immunity on the basis of bioinformatics approaches. Methods Pan-cancer RNA-seq data, mutation profiles, clinical information, TMB, MSI, stemness scores, and tumor and immune microenvironment data contained in TCGA and various open-source online databases, and multi-group R-language algorithms were used for comprehensive analysis. The expression levels of DRGs at the cellular level were experimentally validated using qPCR. Results LRPPRC, NCKAP1, NDUFS1, and NUBPL had a better prognosis in renal clear cell carcinoma (P<0.001), whereas SLC7A11, NCKAP1, and SLC3A2 had a worse prognosis in hepatocellular carcinoma (P<0.001). TME analysis showed that LRPPRC was negatively correlated with immune cells, stromal cells, and estimated scores in all tumor types. TMB analysis revealed the potential research value of DRGs for PD-1/PD-L1 therapy in pan-cancer. Drug sensitivity analysis showed that SLC7A11 (r=0.454), SLC3A2 (r=0.366), and NCKAP1 (r=0.455) were significantly associated with Kahalide F (P<0.01). Experimental validation demonstrated the overall higher expression levels of GYS1 and NCKAP1 than normal cells in lung adenocarcinoma, colon adenocarcinoma, esophageal squamous carcinoma, and hepatocellular carcinoma (P<0.05). Conclusion Pan-cancer analysis of DRGs indicates that DRGs may serve as important biomarkers for the diagnosis and prognosis of renal clear-cell carcinoma, lung adenocarcinoma, and hepatocellular carcinoma.

Objective:To investigate improvement of dexamethasone(DM)treatment after intrauterine adhesion decomposition on uterine fibrosis and inflammatory factors.Methods:A total of 60 patients with moderate to severe intrauterine adhesions admitted to The Reproductive Medicine Center of Jilin Provincial People's Hospital from March 2021 to March 2023 were selected,and divided into experimental group and control group according to random number table method,with 30 cases in each group.Control group under-went simple hysteroscopic adhesion decomposition,and experimental group underwent intrauterine infusion treatment with DM injec-tion after intrauterine adhesion decomposition.Improvement of clinical symptoms in the two groups was observed.RT-qPCR was used to detect changes in mRNA levels of intimal receptivity-related factors ER,EGFR,LIF,ITGB3,HOXA10,HOXA11,fibrosis-related factors TGF-β1,E-cadherin,N-cadherin,Smad,and inflammatory related factors IL-8,IL-2 and CD138 in two groups.Western blot was used to detect changes in expression levels of inflammatory related proteins IL-8,IL-2 and CD138.Results:Compared with before treatment,endometrial thickness,mRNA levels of ER,EGFR,LIF,ITGB3,HOXA10,HOXA11 and E-cadherin were significantly increased,while mRNA levels of TGF-β1,N-cadherin,Smad,IL-8,IL-2 and CD138,protein levels of IL-8,IL-2 and CD138,and endometrial blood flow parameters PI,RI and adhesion were significantly decreased.Eendometrial thickness,mRNA levels of ER,EGFR,LIF,ITGB3,HOXA10,HOXA11 and E-cadherin in experimental group were significantly higher than those in control group,while mRNA levels of IL-8,IL-2,TGF-β1,N-cadherin,Smad,CD138,IL-8,IL-2 and CD138,and endometrial blood flow parameters PI,RI and adhesion were lower than those in control group(P<0.05).Conclusion:Treatment of DM after intrauterine adhe-sion decomposition can improve intrauterine adhesion,blood flow parameters and endometrial receptivity,and prevent the recurrence of intrauterine adhesion,which mechanism may be related to up-regulation of E-cadherin expression and down-regulation of IL-8,IL-2,CD138,TGF-β1,N-cadherin and Smad expressions.

Objective To investigate the effect of polymyxin B(PMB)combined with tigecycline(TGC)on delaying Klebsiella pneumoniae(KP)resistance to PMB,and to analyze the possible mechanisms involved in the induction and delay of resistance.Methods Six clinical isolates of KP strains from the Intensive Care Unit of First Affiliated Hospital of Army Medical University were subjected and then induced with PMB at 1/2 minimal inhibitory concentration(MIC)alone or combined with TGC at 1/2 and 1/4 MIC,respectively.The MIC changes of PMB in these strains were monitored over 14 consecutive passages.The strain 686K,which showed the most significant delay in resistance,was selected for further analysis.Differences in gene and protein expression were examined among the wild-type strain 686K,PMB-induced resistant strain(686K·R),and PMB combined with TGC delayed resistant strain(686K·DR)using transcriptome sequencing,qRT-PCR,and proteomics.Relevant target genes during the delay of resistance were analyzed through literature and bioinformatics analyses.Additionally,cpxR gene knockout strain 686K/ΔcpxR∷Apr and its complementation strain 686K/ΔcpxR∷Apr/pRK415-cpxR were constructed using homologous recombination technology to assess the expression levels of resistance-related genes and changes in MIC after induction in vitro.Results Under sub-MIC(1/2)PMB alone,resistance developed in all 6 KP strains within 2 d,while,the combination with TGC significantly delayed the development of resistance.Transcriptomic and proteomic analyses indicated that in strain 686K·R,the expression levels of the PhoP/Q two-component system,lipopolysaccharide(LPS)modification enzymes,and efflux pump systems were significantly up-regulated(|Log2FC|≥2,P<0.0001),while TGC co-administration markedly inhibited these expression changes.The cpxR deletion and complementation strains were successfully constructed.The expression levels of resistance-related genes phoP,pmrD,and acrA were decreased in the cpxR deletion strain(P<0.001),and the resistance was delayed until day 6 under PMB monotherapy,whereas the complementation strain restored the resistance phenotype by day 2.In the absence of cpxR,the effect of PMB when combined with TGC on delaying resistance did not differ from that observed with PMB monotherapy.Conclusion The combination of PMB and TGC can delay KP resistance to PMB.cpxR,as a critical regulatory factor,can impact PMB resistance by modulating LPS modifications and the expression of the AcrAB-TolC efflux pump,and plays an important regulatory role in the process of resistance induction.

Objective:To explore the relationship between post-traumatic growth and stress perception as well as the chain-mediated roles of psychological resilience and navigating social support in patients with primary liver cancer(PLC), in order to provide theoretical ideas for the nursing and intervention of PLC patients.Methods:Convenience sampling was used to select PLC patients admitted to the First Affiliated Hospital, Third Affiliated Hospital, and Fourth Affiliated Hospital of Xinjiang Medical University from October 2023 to May 2024 as the research subjects. A cross-sectional survey was conducted using Posttraumatic Growth Inventory, the Chinese Perceived Stress Scale, Perceived Social Support Scale, and the Connor-Davidson Resilience Scale.Results:A total of 236 PLC patients were ultimately included, including 189 males and 47 females. Age distribution was as follows: 18-40 years years (7 cases), 41-60 years (128 cases), and ≥61 years (101 cases). Posttraumatic growth showed a significant negative correlation with perceived stress ( r=-0.512, P<0.01), while demonstrating positive correlations with psychological resilience and perceived social support ( r=0.605, 0.515, both P<0.01). Psychological resilience and perceived social support had mediating and chain mediating effects between perceived stress and posttraumatic growth, with mediating effects of -0.176 and -0.069, accounting for 29.24% and 11.46% of the total effect, respectively. The chain mediating effect value was 0.073, accounting for 12.13% of the total effect. Conclusions:The pathway of stress perception on post-traumatic growth in patients with PLC is indirect, and stress perception can contribute to the growth of post-traumatic growth in patients through psychological resilience, and navigating social support.

Objective:To compare the surface electromyography characteristics of essential tremor (ET), Parkinson′s disease (PD) and essential tremor-Parkinson′s disease syndrome (ET-PD).Methods:A total of 74 patients [ET group ( n=23), PD group ( n=30), and ET-PD group ( n=21)] admitted to the Parkinson′s and Movement Disorders Center of the Department of Neurology of Xuanwu Hospital from August 2020 to December 2023 were enrolled, and results of their bilateral upper limbs surface electromyography (sEMG) were collected. sEMG activities were analyzed offline. Power spectral analysis was performed to explore the sEMG activities. One-way analysis of variance and chi-square test were used to compare the differences of electrophysiological parameters. Results:For the ET group characterized by postural tremor, the frequency was (6.06±0.68) Hz, the amplitude was (1 200.91±360.69) μV, the proportion of alternating contractions was 30.4% (7/23), and the proportion of harmonic resonances was 34.8% (8/23). For the PD group characterized by rest tremor, the frequency was (4.81±0.61) Hz, the amplitude was (1 057.40±354.52) μV, the proportion of alternating contractions was 73.3% (22/30), and the proportion of harmonic resonances was 70.0% (21/30). For the ET-PD group in rest and postural state respectively, the frequencies were (5.04±0.44) Hz and (5.80±0.47) Hz, the amplitudes were (1 026.05±191.90) μV and (1 196.67±212.12) μV, the proportions of alternating contractions were 52.4% (11/21) and 38.1% (8/21), and the proportions of harmonic resonances were 52.4% (11/21) and 33.3% (7/21). Analysis of variance revealed that tremor frequencies for the PD group and the ET-PD group in rest state were lower than the ET group and the ET-PD group in postural state ( F=27.439, P<0.001). The proportion of alternating contractions for the PD group was higher than the ET group ( χ 2=9.669, P=0.002) and the ET-PD group in postural state ( χ 2=6.333, P=0.012). The proportion of harmonic resonances for the PD group was higher than the ET group ( χ 2=6.517, P=0.011) and the ET-PD group in postural state ( χ 2=6.708, P=0.010). No statistically significant differences were found for tremor amplitudes among all the groups ( F=2.143, P=0.100). Conclusions:ET is characterized by postural tremors, with a higher frequency and a lower alternating contractions and harmonic resonances. PD is characterized by rest tremors, with a lower frequency and a higher alternating contractions and harmonic resonances. The parameters of ET-PD are between ET and PD, which provide objective evidences for differential diagnosis of tremors.
