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 analyze the serological characteristics and molecular biology results for a P^k phenotype. [Methods] One patient with P^k phenotype upon unexpected antibodies at Jining Blood Center in July 2022 was selected as the study subject. The blood groups and unexpected antibodies of the proband and his second son were identified using serological methods. The sequences of 3-β-N-acetylgalactosaminyltransferase gene (B3GALNT1) and the coding region of α-1,4-galactosyltransferase gene (A4GALT) were amplified and analyzed by PCR direct sequencing, and haploid sequence analysis was carried out on the variant sites of the B3GALNT1 gene. PROVEAN, SIFT, PolyPhen2 and Mutation Taster were used to analyze the effect of mutations on the protein. [Results] Serological test results suggested that the proband was a P2^k type, including anti-P antibody in his serum, and his son was the P2 phenotype. Sequencing analysis revealed that the proband had a compound heterozygous variants of the B3GALNT1 in c. 239T>A (p. Leu80Gln) and c. 433C>T (p. Arg145Ter). Further haploid analysis showed that the c. 239T>A had occurred in one haploid while c. 433C>T was present in the other haploid, and his son carried a heterozygous variant of c. 433C>T (p. Arg145Ter); the proband and his son all have homozygous mutation variants of the A4GALT in c. 903C>G. Bioinformatic analysis also predicted that the mutations were harmful to the protein function. [Conclusion] The compound heterozygous variants c. 239T>A (p. Leu80Gln) and c. 433C>T (p. Arg145Ter) in the B3GALNT1 gene may contribute to the P^k phenotype, of which the c. 239T>A variant has not been reported.

AIM:To investigate the effect of cellular Sloan-Kettering Institute(c-SKI)protein expression on myocardial fibrosis in mice treated with andrgrapholide(Andr).METHODS:Male C57 mice were randomly divided into control group,model group[isoprenaline(ISO)group]and ISO+Andr group,with 6 mice per group.The mice in ISO and ISO+Andr groups were subcutaneously injected with ISO,while those in control group were injected with normal sa-line.The mice in ISO+Andr group was intragastrically given Andr,while those in ISO and control groups were given nor-mal saline.The histopathological characteristics of the heart tissue were detected by HE and Masson staining after 8 weeks of administration.The expression levels of c-SKI and extracellular matrix(ECM)-related proteins were detected by immu-nohistochemistry or Western blot.The c-SKI mRNA level was detected by qPCR.Human cardiac fibroblasts(HCFBs)were treated with different concentrations of Andr for 48 h.The cell viability was detected by CCK-8 assay,and the c-SKI and ECM-related protein levels were detected by Western blot.The transdifferentiated cell model was treated with the lowest effective dose of Andr.The cell morphology was observed under a microscope,the levels of c-SKI and ECM-related pro-teins were assessed by Western blot,and the c-SKI mRNA level was detected by qPCR.The transforming growth factor-β1(TGF-β1)-treated HCFBs were treated with the combination of c-SKI knockdown and Andr.The cell viability was detected by CCK-8 assay,and the levels of c-SKI and ECM-related proteins were detected by Western blot.RESULTS:After the intervention of Andr,the myocardial fibers in mice were neatly arranged,the morphology of myocardial cells was basically normal,the cell membrane was intact,and the collagen volume fraction was significantly reduced(P＜0.01).The mRNA and protein levels of c-SKI were significantly up-regulated(P＜0.05 or P＜0.01),and the protein levels of fibronectin 1(FN1),α-smooth muscle actin(α-SMA),vimentin and collagen type I(Col I)were significantly down-regulated(P＜0.01).After 50 μmol/L Andr treatment for 48 h,the viability of HCFBs was significantly decreased(P＜0.01),the pro-tein levels of Col I,α-SMA,vimentin and FN1 were significantly down-regulated(P＜0.01),and c-SKI expression was significantly up-regulated(P＜0.01).Compared with PBS group,the number of the HCFBs in TGF-β1 group increased with flattened and irregular morphological change,and the FN1,α-SMA,Col I and vimentin levels were significantly in-creased(P＜0.01),while c-SKI expression was significantly decreased(P＜0.01).After Andr intervention,the induction effect of TGF-β1 on HCFBs was reversed.Knockdown of c-SKI combined with Andr treatment in HCFBs significantly down-regulated c-SKI expression(P＜0.01),significantly up-regulated FN1,α-SMA,vimentin and Col I levels(P＜0.05),and significantly increased the cell viability.CONCLUSION:Andrgrapholide may affect the TGF-β1 signaling pathway by regulating c-SKI expression,and inhibit the proliferation of myocardial fibroblasts and ECM deposition,thus inhibiting myocardial fibrosis.

Objective To explore the effect of sorafenib on HeLa cell proliferation by inducing cell apoptosis and autophagy and its impact on drug resistance.Methods The drug-resistant cell strains were constructed through in-termittent induction method,with concentrations of 0,2.5,5.0,7.5,10.0,15.0,20.0 μmol/L.HeLa cells were incubated with increasing concentrations of sorafenib with each concentration for 1 week.The drug-resistant cell strains with stable passages were collected.MTT assay was used to detect the effect of sorafenib on cell prolifer-ation.Cell cycle distribution was analyzed by flow cytometry.The change in the expression of drug-resistant and ap-optotic genes in the parents and drug-resistant cell strains under different drug concentrations was examined by semi-quantitative PCR.The changes of apoptotic related marker proteins LC3-Ⅰ and LC3-Ⅱ were detected by Westernblot.Results Stable drug-resistant strains were successfully obtained;Drug-treated cells were more blocked in the G1 phase.In drug-resistant cells,the expression of apoptosis suppressor gene Bcl-2 was significantly decreased and the apoptotic gene Bax as well as the drug-resistant genes were all significantly increased(P＜0.05).The LC3-Ⅱ/LC3-Ⅰ ratio of drug-resistant cells was significantly higher than that of parent cells(P＜0.05).Conclusions Sorafenib may block the cell cycle,suppress malignant cell proliferation and promote autophage.On one hand,autophagy participates in the development of cell drug resistance and promotes cell survival.On the other hand,drug-induced autophagy may activate some of apoptotic signaling pathway in drug-resistant cells and promote the reversal of cell drug resistance.

BACKGROUND:As a bone replacement and filling material,calcium phosphate stone bone cement has good biocompatibility,bone conductivity,and other advantages,especially its better biodegradability compared to other calcium phosphate bone cements.It has important application value in bone repair.However,due to its limitations such as insufficient mechanical properties,fast solidification reaction,and poor injection performance,it is currently only suitable for the repair of non weight-bearing bone. OBJECTIVE:To explore the modification of brushite cements with bioactive ions(metal and non metal ions)to expand its application range. METHODS:The author used PubMed,ScienceDirect,CNKI,and WanFang to search the literature published between 2018 and 2023 with the search terms"metal ion,iron,copper,strontium,magnesium,zinc,non-metal ion,modification,bone,brushite cements"in Chinese and"metal ion,iron,Fe,copper,Cu,strontium,Sr,magnesium,Mg,zinc,Zn,non-metal ion,modification,bone,brushite cements"in English.After reading titles and abstracts,the articles were initially screened,and irrelevant and duplicate articles were excluded.Finally,64 articles were included for review. RESULTS AND CONCLUSION:(1)Bioactive ions affect the hydration process of calcium phosphate bone cement.Different ions are substituted by ions and incorporated into the crystal structure of calcium phosphate bone cement,changing the crystal morphology of the cement and causing changes in physical and chemical properties such as setting time,injectability,and compressive strength.(2)Ionic modified calcium phosphate bone cement produces different ion release effects due to different crystal structures.Different types of ions have properties such as promoting angiogenesis/osteogenesis,antibacterial,anti-tumor,etc.In addition,calcium phosphate bone cement has good biodegradability,which has great advantages for the performance of various ions.(3)The physicochemical properties of calcium phosphate bone cement modified with different ions are as follows:iron,copper,strontium,magnesium,zinc,silver,and cobalt can prolong the setting time.Strontium,and magnesium can improve injection performance.Copper,strontium,magnesium,silver and silicon can enhance compressive strength.The ions that can simultaneously improve the three physical and chemical properties of calcium phosphate bone cement include strontium and magnesium.Good physical and chemical properties are a prerequisite for clinical application,so improving the setting time,injectability,compressive strength,and other properties of calcium phosphate bone cement with ions is of great significance for the research and application of bone cement.(4)The biological properties of calcium phosphate bone cement modified with different ions are as follows:copper,strontium,magnesium,zinc,cobalt,lithium,selenium,and silicon have promoting angiogenesis/osteogenic effects.Iron,copper,magnesium,zinc,and silver have antibacterial properties.Magnesium ions have anti-inflammatory properties.Copper and selenium have anti-tumor properties.(5)In summary,magnesium ions can improve the setting time,injectability,and compressive strength of calcium phosphate bone cement,while also promoting neovascularization/osteogenesis,antibacterial properties,and have good application prospects for the treatment of bone defects with concurrent infections.In addition,copper also has anti-tumor properties,so copper ions have great potential in the treatment of bone defects caused by infections and tumors.However,relevant research is still in the basic research stage,and the effects of different ion doping concentrations and synthesis conditions on the physicochemical properties of calcium phosphate bone cement need to be further explored.At the same time,the impact of biological properties also needs to be studied and observed for a longer period of time.

Objective:To investigate the characteristics of neointimal hyperplasia (NIH) in patients with in-stent restenosis (ISR) over 5 years post-drug-eluting stent (DES) implantation based on optical coherence tomography (OCT).Methods:In this cross-sectional study, patients with DES-ISR who underwent OCT examination at PLA General Hospital between March 2010 and March 2022 were retrospectively included. All patients were divided into≤5 years DES-ISR group and>5 years DES-ISR group according to the time interval after DES implantation. Quantitative and qualitative analyses were conducted on OCT images to compare the clinical data and lesion characteristics of two patient groups. Furthermore, the independent clinical predictive factors of in-stent neoatherosclerosis (ISNA) were analyzed by multivariable logistic regression.Results:A total of 230 DES-ISR patients with 249 lesions were included, with an age of (63.1±10.4) years and 188 males (81.7%). The median interval after DES implantation was 6 (2, 9) years. There were 117 patients (122 ISR lesions) in the≤5 years DES-ISR group, and 113 patients (127 ISR lesions) in the>5 years DES-ISR group. Compared with≤5 years DES-ISR,>5 years DES-ISR showed more heterogeneous patterns (65.4% (83/127) vs. 48.4% (59/122), P=0.007), diffuse patterns (46.5% (59/127) vs. 31.2% (38/122), P=0.013), macrophage accumulations (44.1% (56/127) vs. 31.2% (38/122), P=0.035) in NIH and higher prevalence of ISNA (83.5% (106/127) vs. 72.1% (88/122), P=0.031). According to multivariable logistic regression, the independent predictive factor for ISNA was female ( OR=0.44, 95% CI 0.21-0.90, P=0.026). Female ( OR=0.48, 95% CI 0.23-0.99, P=0.046) and low-density lipoprotein cholesterol level ( OR=1.62, 95% CI 1.01-2.59, P=0.046) were independent predictive factors, respectively, for lipid ISNA. Calcified ISNA was independently associated with time interval of post-DES implantation ( OR=1.18, 95% CI 1.07-1.29, P=0.001). Conclusion:DES-ISR patients with a time interval of>5 years after stent implantation have a higher prevalence of ISNA and more complex lesions. Gender, the level of low-density lipoprotein cholesterol, and the time interval post-DES implantation are independently correlated with ISNA, lipid ISNA, and calcified ISNA.

Objective:To explore the relationship between olfactory dysfunction and mild cognitive impairment (MCI) among elderly people in the community so as to provide a reference for screening and risk factor management of the MCI population.Methods:From March to June 2023, elderly individuals from Donghuashi and Fangzhuang communities in Beijing were selected as the study subjects by convenience sampling. Study subjects were surveyed using the General Information Questionnaire, Mini-Mental State Examination, Montreal Cognitive Assessment, Barthel Index, Sniffin' Sticks Test, 7-item Generalized Anxiety Disorder Scale, and 15-item Geriatric Depression Scale. Binary logistic regression was used to analyze the factors that influence MCI among elderly people in the community.Results:A total of 252 questionnaires were distributed and 243 valid questionnaires were collected, with an effective response rate of 96.4% (243/252). Among 243 elderly people in the community, 75 experienced MCI, with an incidence of 30.9% (75/243). Binary Logistic regression analysis showed that the probability of MCI in elderly people with olfactory dysfunctions was 1.979 times that in elderly people without olfactory dysfunctions and age, previous occupational type and frequency of mental activity were the influencing factors for the occurrence of MCI ( P<0.05) . Conclusions:The incidence of MCI is high among elderly people in the community, especially those with olfactory dysfunctions. Nursing staff should pay attention to the role of olfactory dysfunction in cognitive function screening and risk factor management.

Objective:To carry out a scoping review on characteristics and effects of intervention program for promoting motor behavior among older adults in the community based on transtheoretical model (TTM), so as to explore the mechanism and connotation of TTM guiding strategy selection in the intervention program.Methods:The literature on the intervention program for promoting motor behavior among older adults in the community based on TTM was systematically searched in PubMed, Embase, CINAHL, Cochrane Library, PsycINFO, China National Knowledge Infrastructure and Wanfang Data. The search period was from database establishment to October 11, 2023. Two researchers conducted a summary and data analysis of the included literature.Results:A total of 15 articles were included, and the intervention framework included two types according to behavior change stages and behavior change patterns. The intervention strategy mainly included 17 items, such as emphasizing the benefits of exercise and drawbacks of no-exercise, establishing family support relationships, sharing exemplary experiences, rewarding, setting reminders, and signing commitments. The intervention strategies mainly involved 14 forms such as health lectures, one-on-one communication, exercise commitment letters, exercise logs, group communication meetings, and material/honor. The outcome measures consisted of feasibility (safety, retention, attendance, satisfaction) and effectiveness (exercise compliance, behavioral stage changes, physical function, self-efficacy, decision balance and so on) .Conclusions:The stages of change in TTM can guide the design of intervention frameworks for promoting motor behavior among older adults in the community, and the change program can guide the intervention strategies and design of application forms. The characteristic of the TTM based intervention program for promoting motor behavior among older adults in the community is that it contains intervention strategies that are suitable for each stage of behavior, and has short-term effectiveness and feasibility in terms of results. It is necessary to further clarify the details of the intervention program to explore its long-term effectiveness, and conduct follow-up.

Objective:To conduct a scoping review on gamified exercise interventions for elderly patients with cognitive impairment to provide insights for the application of gamification design in exercise programs for this population.Methods:Guided by the scoping review framework proposed by Arksey and O'Malley, a systematic search was conducted in databases including China National Knowledge Infrastructure, Wanfang, VIP, SinoMed, PubMed, Cochrane Library, CINAHL, Web of Science, Scopus, ProQuest, and Wiley Online Library. The search covered the period from the establishment of the databases to June 12, 2024. An integrative analysis was performed on the included literature.Results:A total of 12 studies were included. The most commonly used gamification elements were achievement- and progress-oriented features, while the most frequently applied behavior change theories were behavior change techniques and social cognitive theory.Conclusions:Gamification-based exercise interventions can improve adherence to exercise programs in elderly patients with cognitive impairment, promote physical activity, and enhance cognitive function. Future research should focus on combining various theories with different gamification elements to encourage proactive exercise behavior in elderly individuals with cognitive impairment.

Objectives:Present study analyzed the efficacy and safety of percutaneous coronary intervention(PCI)using the distal transradial access(dTRA)for patients with complex coronary lesions. Methods:A total of 10 033 patients with complex coronary artery lesions(type B2 and type C lesions)who underwent percutaneous coronary intervention(PCI)via dTRA or conventional transradial access(TRA)at Fuwai Hospital between June 2021 and May 2022 were included(9 625 patients in the TRA group and 408 patients in the dTRA group).After propensity score matching,391 patients were included in each group.Baseline data,PCI intraoperative data(including lesion characteristics,intervention success rate,etc.),and incidence of major bleeding related to the access were compared between the two groups before and after propensity score matching. Results:Before propensity score matching,the proportions of patients with hypertension,hyperlipidemia,family history of coronary heart disease,history of myocardial infarction,and history of coronary artery bypass grafting were significantly higher in the dTRA group than in the TRA group(all P<0.05).After propensity score matching,the baseline data of the two groups were similar(all P>0.05).Before propensity score matching,compared with the TRA group,patients in the dTRA group had a higher proportion of patients with type B2 lesions,while the proportions of patients with type C lesions and those using intravascular ultrasound(IVUS)were lower(all P<0.05).The proportion of patients with chronic complete occlusion was similar between the two groups(P>0.05).After propensity score matching,compared with the TRA group,patients in the dTRA group had a lower proportion using IVUS and had a higher percent of stent implantation(both P<0.05).There was no statistically significant difference between the two groups in terms of SYNTAX score,guide catheter size,target lesion distribution,proportion of patients using intra-aortic balloon counterpulsation,success rate of intervention procedures,and incidence of major bleeding events related to the access(all P>0.05). Conclusions:Compared with the conventional TRA,interventional treatment of complex lesions through dTRA is equally safe and effective for patients with complex coronary lesions.
