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.

BACKGROUND/OBJECTIVES: A 5:2 intermittent fasting (IF) program is an effective dietary intervention for patients who are overweight or obese, but the effects of a 5:2 IF diet on the Chinese population are unclear. This study examined the impact of a modified 5:2 IF dietary intervention on Chinese adults who were overweight or obese. SUBJECTS/METHODS: In this self-controlled clinical trial, 45 overweight or obese participants received a modified 5:2 IF dietary intervention for 24 weeks. The body weight, body mass index (BMI), waist circumference (WC), glycolipid metabolism indicators, adipokines, and inflammatory factors were measured in all participants at weeks 0 and 24. The changes in body weight and glycolipid metabolism indicators were the primary outcomes. Serum metabolomics analysis was conducted to identify the differences in metabolites and potential metabolic pathways after dietary intervention. RESULTS: Thirty-one participants completed the trial and were included in the final analysis.After 24 weeks of a modified 5:2 IF dietary intervention, the participants showed significant decreases in the BMI, WC, body weight, levels of fasting plasma glucose, fasting plasma insulin, total cholesterol, low-density lipoprotein-cholesterol, interleukin 6, tumor necrosis factor-alpha, alanine aminotransferase, and uric acid (all P < 0.05). Moreover, serum metabolomics analysis identified several significantly altered metabolites and metabolic pathways, including pyruvic acid, alpha-ketoisovaleric acid, ammonia recycling, and glutamate metabolism. CONCLUSION A modified 5:2 IF dietary intervention significantly reduced the body weight in Chinese adults who were overweight or obese.

Objective To establish a rat model of venous thrombosis in a plateau hypobaric hypoxic environment and to investigate the effect of this environment on venous thrombosis.Methods A total of 144 healthy male SD rats were assigned randomly to four groups(n=36 rats per group):a plains sham operation(A)group,plains operation(B)group,plateau altitude 6000 m+sham operation(C)group,and plateau altitude 6000 m+surgery(D)group.Rats in A and B groups were maintained in a plains normoxic environment,while rats in C and D groups C and D were subjected to a plateau environment.Rats in the surgical groups underwent quantitative constriction to incompletely obstruct the inferior vena cava blood flow.Each group was further divided into subgroups based on time:1,3,5,7,14,and 21 d(n=6 rats per group).Regular vascular ultrasound monitoring was conducted,and blood samples were taken for whole blood viscosity testing and the assessment of inflammatory indicators,including endothelin-1(ET-1),interleukin-6(IL-6)and tissue factor(TF).Coagulation function was evaluated through the activated partial thromboplastin time(APTT),prothrombin time(PT),thrombin time(TT),fibrinogen(FIB)and D-dimer.After the observation period,the experimental animals were sacrificed and the limbs were removed.Thrombus samples were stained with hematoxylin/eosin(HE),and the thrombus wet mass was measured.Results The thrombosis incidence was significantly higher in the plateau D group than in B group,accompanied by a marked increase in blood viscosity and hematocrit(P＜0.01).Additionally,levels of ET-1,IL-6,and TF were significantly elevated(P＜0.05),indicating a coagulation disorder.Conclusions A plateau hypoxic environment model can be successfully simulated by quantitative coarctation of the inferior vena cava,combined with a specialized environmental chamber.The findings of this study suggest that a plateau hypoxic environment promotes venous thrombosis.

Objective To investigate the effect of unilateral or bilateral transcranial direct current stimulation(tDCS)on post-stroke dysphagia.Methods From February,2023 to March,2025,27 stroke patients with dysphagia and nasal feeding in Beijing Bo'ai Hos-pital were randomly divided into healthy side stimulation group,bilateral stimulation group and sham stimulation group,with nine cases in each group.All the groups received conventional swallowing training and tDCS,while the healthy side stimulation group stimulated on the healthy side of oropharyngeal cortex;and the bilateral stimu-lation group alternatively stimulated bilateral oropharyngeal cortex,with one hour interval between bilateral stim-ulation;the sham stimulation group stimulated the healthy side of oropharyngeal cortex for 30 seconds and then stop.The course lasted two weeks.The scores of Standard Swallowing Function Assessment Scale(SSA),Modi-fied Mann Assessment of Swallowing Ability(MMASA)and Rosenbek Penetration-Aspiration Scale(PAS)were compared before and after treatment.Results The intra-group effect(F=16.185,P<0.01)was significant in the scores of SSA,the intra-group effect(F=28.650,P<0.01)and interaction effect(F=3.453,P<0.01)were significant in the scores of MMASA,and there was no significant difference in the inter-group effect,intra-group effect and interaction effect in the scores of PAS(P>0.05).Post hoc test showed that there was no significant difference in the scores of SSA,MMASA and PAS among three groups(P>0.05).There was significant difference in the score difference of MMASA be-fore and after treatment among three groups(F=4.698,P<0.05).Post hoc test showed that the score difference of MMAS was more in the healthy side stimulation group than in the bilateral stimulation group and the sham stimulation group(P<0.05),with no significant difference between the bilateral stimulation group and the sham stimulation group(P>0.05).Conclusion tDCS can partly improve post-stroke dysphagia.The healthy side anode stimulation is superior to the alter-nating bilateral hemisphere anode stimulation.

During decidualization, lactic acid is produced and accumulated in large amounts, becoming a prominent feature of the decidual microenvironment. Lactic acid not only serves as a key product in metabolic pathways, participating in rapid energy generation and conversion, but also influences cellular functional states by regulating the acid-base balance of the microenvironment. Furthermore, as a signaling molecule, lactic acid plays a central role in regulating decidual immune metabolism, promoting decidual angiogenesis, and facilitating trophoblast invasion, all of which are crucial for embryo implantation. In recent years, the role of lactic acid in epigenetics has also gradually emerged, with lactylation modifications involved in regulating gene expression and maintaining the homeostasis of the decidual microenvironment. This article will delve into the specific roles of lactic acid in the decidual microenvironment, aiming to provide new perspectives and theoretical foundations for the study of pregnancy-related diseases.

Objective:To study on the relationship between serum levels of SC and SV and insulin resistance in elderly gestational diabetes mellitus.Methods:120 elderly patients with GDM were treated in Obstetrics Department of Yantai Yuhuangding Hospital from Jun. 2019 to Jun. 2021. The healthy women (58 cases) and normal pregnant women (58 cases) were selected as the control group at the same time, and the clinical data and serum samples of subjects were collected. The levels of serum SC, SV, FPG and HbAlc were measured, the HOMA-IR of the aged GDM was calculated, and the difference of serum index expression among the subjects in each group was analyzed. The relationship between serum SC, SV and insulin resistance was analyzed by Person correlation, and the risk factors of GDM were analyzed by Logistic regression.Results:: There was significant difference in HbAlc, HOMA-IR, FPG, SC, and SV among the three groups. The levels of each index in the elderly GDM group were significantly higher than those in the normal pregnancy group and the healthygroup ( P<0.05). Pearson analysis showed that SC ( P=0.558, 0.626, 0.672), SV ( P=0.576, 0.663, 0.696) was positively correlated with HbAlc, HOMA-IR, FPG in elderly patients with GDM ( P<0.001). Logistic regression analysis showed that SC, SV was risk factors for GDM in elderly pregnant women. Conclusion:There is a positive correlation between serum SC, SV level and insulin resistance, which are risk factors for GDM in elderly pregnant women.

Objective:Children below 14 years of age are highly vulnerable to dengue infection and are at a greater risk of developing severe dengue illness.This study aimed to investigate the trends in the burden of dengue fever among children below 14 years of age in China from 1990 to 2021 and to project the disease burden from 2022 to 2035.Methods:Based on the datasets derived from the Global Burden of Disease Study 2021,the following data were collected from dengue-affected children aged ≤14 years in China from 1990 to 2021:number and rate of incident dengue cases,number of prevalent dengue cases,number of deaths due to dengue,and disability-adjusted life years(DALYs)lost due to dengue.The trends in disease burden were examined based on average annual percent change(AAPC)and annual percent change,and the burdens were projected from 2022 to 2035 by using a Bayesian age-period-cohort model.Results:The incidence and prevalence of dengue fever were increased in children aged ≤14 years in China from 1990 to 2021(AAPC=5.42％and 5.44％,respectively,P＜0.001),while the mortality and DALYs rates were reduced(AAPC=-8.21％and-7.55％,respectively,P＜0.001).The burden was comparable between genders,with numerically lower incidence and prevalence in boys than in girls.The lowest incidence and prevalence and the highest mortality and DALYs rates were observed in children aged＜5 years.The incidence and prevalence rates were projected to increase from 2022 to 2035;in contrast,the mortality and DALYs rates were projected to decrease during this period.Conclusions:Although the mortality and DALYs rates of dengue fever decreased significantly in children aged 0-14 years in China from 1990 to 2021,the incidence and prevalence increased remarkably.Enhanced surveil-lance and ample health education programs and preventive interventions are recommended for targeting this high-risk population.

Cancer-associated venous thromboembolism(CAT)refers to the presence of venous thromboem-bolism including deep vein thrombosis and pulmonary embolism in patients with malignant cancer.Studies have indicated that CAT has become the second leading cause of death among cancer patients.Similar to other methods used to prevent and treat venous thromboembolism,anticoagulation remains to be the primary approach for CAT.However,the occurrence of CAT is influenced by various factors such as tumor type,staging,complications,treat-ment,and prognosis.This complexity makes the prevention and management of CAT more difficult and challeng-ing.This article reviews the classification of commonly used anticoagulant drugs in clinical practice,emphasizing the current status and advancements in their application for the prevention and treatment of cancer-related venous thromboembolism in order to provide valuable reference for clinical medication.

Purpose This study aims to analyze genetic mutations in patients with BCR ∷ABL negative myelopro-liferative neoplasms(MPN)and to explore their relationship with clinical features.Methods We retrospectively ana-lyzed the clinical data of 208 patients diagnosed with BCR ∷ABL negative MPN,which included 34 patients with poly-cythemia vera(PV),33 with essential thrombocytopenia(ET),and 141 with primary myelofibrosis(PMF).Mutations in driver genes were assessed in all patients.A total of 72 patients underwent next-generation sequencing(NGS)with 69-gene panel,and the relationship between gene mutations and clinical features were analyzed.Results Among the 208 MPN patients,at least one driver gene mutation(JAK2,CALR,MPL)was detected in 96.15％(200/208)of the patients.Only 0.48％(1/208)of the patients exhibited both JAK2 and CALR driver mutations.We analyzed the clinical data of 136 patients with only driver gene mutations to compare the relationship between the most common JAK2 mutations(identified in 110 patients)and clinical outcomes.The JAK2 mutation group demonstrated higher white blood cell(WBC)counts and lower platelet(PLT)counts compared to the group without JAK2 mutations.173 muta-tions in 40 genes were detected in 72 patients,per capita carried(2.40±1.40)mutations.TET2,ASXL1,and TP53 are the most prevalent non-driver gene mutations,with 44.4％(32/72)of patients exhibiting at least one mutation in these three genes.In comparison to patients without detected mutations in TET2,ASXL1,and TP53,those with muta-tions in these genes demonstrated lower hemoglobin(HGB)levels,a higher incidence of splenomegaly,and more se-vere bone marrow fibrosis.High-molecular risk category(HMR)mutations were detected in 22.22％(16/72)of the patients,and patients with HMR exhibited lower hemoglobin(HGB)levels,lower PLT counts,a higher likelihood of peripheral blood primitive cell percentage ≥ 1％,a greater incidence of splenomegaly,and more severe myelofibrosis.Mutations in the ASXL1 gene were exclusively observed in patients with PMF.Among the PMF patients with ASXL1 mutations(12 patients),there was a higher likelihood of having a peripheral blood primitive cell percentage of ≥1％,as well as a more severe degree of myelofibrosis.Conclusion Approximately 97％of patients with myeloproliferative neoplasms(MPN)exhibit positivity for driver genes,with a notably high mutation rate of the JAK2 gene.Each sub-group of MPN is characterized by distinct gene mutation patterns.Notably,ASXL1 mutations are exclusive to patients with primary myelofibrosis(PMF).Furthermore,PMF patients harboring ASXL1 mutations tend to demonstrate more pronounced bone marrow fibrosis and a greater proportion of blast cells in peripheral blood.

Objective:To analyze the short-term hospital-based transmission characteristics and gene variation of Carbapenem-Resistant Klebsiella pneumoniae (CRKP) by genome-wide technique to provide evidence for transmission control. Methods:The experimental strain was derived from all the CRKP isolated in Affiliated Hospital of North China University of Science and Technology from October 2022 to December 2023. Strain identification and drug susceptibility were tested with VITEK 2-Compact automatic bacterial identification drug susceptibility analyzer or disk method, and the results were interpreted through whole genome sequencing. The ST type, carbapenem resistance gene, virulence factor, and O serotype of the collected strains were analyzed.Results:Among the 115 strains of CRKP, 94 strains were isolated from the intensive care unit (ICU), accounting for 81.7%, and 21 strains were isolated from the non-intensive care unit (NICU), accounting for 18.3%. The 115 strains of CRKP can be divided into 11 ST types, of which ST11 type was the most (54.8%, 63/115), followed by ST15 type (22.6%, 26/115) and ST5492 type (15.7%, 18/115). Type ST5492 was a new clonal group in the region. The 115 strains of CRKP could be divided into 7 O serotypes, most of which were O2a type(32.2%,37/115), followed by O5 type(30.4%,35/115) and O1 type(27.8%,32/115). The resistance genes of carbapenem antibiotics showed that there were 107 strains carrying the blaKPC-2 gene, one strain with the blaNDM-1 gene, and one strain with both the blaKPC-2 and blaNDM-13 genes. Virulence genes were detected in 55 CRKP strains (47.8%, 55/115), among which six strains detected peg-344, iucA, iroB, rmpA, and rmpA2 virulence genes (5.2%, 6/115). Four virulence genes ( peg-344, iucA, rmpA, and rmpA2) were detected in 34 strains (29.6%, 34/115). Three virulence genes ( iucA, iroB and rmpA) were detected in two strains (1.7%, 2/115). Three virulence genes ( peg-344, iucA and rmpA) were detected in one strain (0.8%, 1/115). IucA and rmpA virulence genes were detected in 12 strains (10.4%, 12/115). KPC-2_ST11_O2a, KPC-2_ST15_O1 and KPC-2_ST5492_O5 were dominant clones, and their distribution was mainly in the intensive care unit. The whole genome sequence analysis showed that there were three dominant clones, among which ST11 clones were subdivided into three dominant O serotypes, all of which were mainly in the intensive care unit. Conclusion:The popular strain in the hospital of CRKP is a KPC-2_ST11 clone group carrying iucA, rmpA/rmpA2, with cross-department transmission and mutation. ST5492 is a newly-launched clone type. The intensive care unit of hvKP carrying five virulence genes, including peg-344, should be alert to the epidemic risk of CR-hvKP outbreak.
