Houpo Sanwutang， included in the Catalogue of Ancient Classical Prescriptions （Second Batch）， was first recorded in the Synopsis of Golden Chamber written by ZHANG Zhongjing from the Eastern Han dynasty and was modified by successive generations of medical experts. A total of 37 pieces of effective data involving 37 ancient Chinese medical books were retrieved from different databases. Through literature mining， statistical analysis， and data processing， combined with modern articles， this study employed bibliometrics to investigate the historical origin， composition， decoction methods， clinical application， and other key information. The results showed that the medicinal origin of Houpo Sanwutang was clearly documented in classic books. Based on the conversion of the measurements from the Han Dynasty， it is recommended that 110.4 g Magnolia Officinalis Cortex， 55.2 g Rhei Radix et Rhizoma， and 72 g Aurantii Fructus Immaturus should be taken. Magnolia Officinalis Cortex and Aurantii Fructus Immaturus should be decocted with 2 400 mL water first， and 1 000 mL should be taken from the decocted liquid. Following this， Rhei Radix et Rhizoma should be added for further decoction， and then 600 mL should be taken from the decocted liquid. A single dose of administration is 200 mL， and the medication can be stopped when patients restore smooth bowel movement. Houpo Sanwutang has the effect of moving Qi， relieving stuffiness and fullness， removing food stagnation， and regulating bowels. It can be used in treating abdominal distending pain， guarding， constipation， and other diseases with the pathogenesis of stagnated heat and stagnated Qi in the stomach. The above results provide reference for the future development and research of Houpo Sanwutang.

Pre-admission is a critical initiative to optimize medical service processes and alleviate the challenge of "difficult access to healthcare. "However, there is currently a lack of standardized protocols for pre-admission procedures. This study aims to systematically analyze key nodes and risk factors in pre-admission process design and propose optimization strategies, providing a foundation for policy formulation and hospital practices. By constructing a "forward-reverse" dual-process model of pre-admission and identifying risk points based on stakeholder theory (patients, hospitals, healthcare administration, and insurance), the study reveals that while pre-admission can reduce the average length of stay, improve bed turnover rates, and enhance patient satisfaction, it also presents risks such as cross-period financial settlement, challenges in insurance policy adaptability, demands for information system integration, and the need for defining medical safety boundaries. To optimize the pre-admission process and mitigate these risks, this study explores framework improvements in areas including eligibility criteria, mode selection, cost settlement, transition between pre-admission and inpatient status, and cancellation of pre-admission, offering practical guidance for public hospitals. The authors argue that pre-admission requires tripartite collaboration among hospitals, insurers, and healthcare administrations: hospitals should establish top-level design, continuously refine processes, and implement dynamic risk assessment mechanisms; insurance providers should support cross-period settlement policies; and healthcare administrations should issue guiding policies or standardized protocols. Through multi-department coordination and collaborative efforts, the optimization and innovation of pre-admission processes can be advanced, ultimately delivering more efficient and convenient healthcare experiences for patients.

To explore the common irritant components in different base sources of Polygonati Rhizoma(PR). A rabbit eye irritation experiment was conducted to compare the irritant effects of raw products of Polygonatum kingianum, P. officinale, and P. multiflorum. The irritant effects of different solvent extraction parts and needle crystals of PR were compared, and the irritant components were screened. The morphology and structure of the purified needle crystal of PR were observed by microscope and scanning electron microscope and characterized by X-ray diffraction. Rabbit eye irritation and mouse abdominal inflammation model were used to evaluate rabbit eye irritation scores, inflammatory mediators, inflammatory factors levels in the peritoneal exudate of mice, with the peritoneal pathological section used as indicators. The inflammatory effect of needle crystals of PR was studied, and the content of calcium oxalate in three kinds of PR was determined by HPLC. The common protein in three kinds of PR was screened and compared by double enzymatic hydrolysis in solution combined with mass spectrometry. The results showed that three kinds of PR raw products had certain irritant effects on rabbit eyes, among which P. kingianum had the strongest irritant effect. There were no obvious irritant effects in the different solvent extraction parts of P. kingianum. Compared with the blank group, the needle crystal of PR had a significant irritant effect on rabbit eyes, and the inflammatory mediators and inflammatory factors in the peritoneal exudate were significantly increased(P<0.05) in a dose-dependent manner. Meanwhile, the peritoneal tissue of mice was damaged with significant inflammatory cell infiltration after intraperitoneal injection of needle crystal, indicating that needle crystal had an inflammatory effect. Microscope and scanning electron microscope observations showed that the needle crystals of PR were slender, with a length of about 100-200 μm and sharp ends. X-ray diffraction analysis showed that the needle crystals of PR were calcium oxalate monohydrate crystals. The results of HPLC showed that the content of calcium oxalate in P. kingianum was the highest among the three kinds of PR. It was speculated that the content of needle crystal in P. kingianum was higher than that in P. officinale and P. multiflorum, which was consistent with the results of the rabbit eye irritation experiment. The results of mass spectrometry showed that ribosome inactivating protein and mannose/sialic acid binding lectin were related to inflammation and cell metabolism in all three kinds of PR. There was no obvious irritant effect in different solvent extracts of PR. The calcium oxalate needle crystal contained was the main irritant component of PR, and three kinds of PR contained common ribosome inactivating protein and mannose/sialic acid binding lectin, which may be related to the inflammatory irritant effect of PR.

DNA damage triggers cells to initiate a series of DNA damage response(DDR),including DNA damage repair,cell cycle checkpoint activation,cell cycle arrest,activation of various intracellular signal transduction pathways,and cell apoptosis,etc.DNA Damage Repair,an important mechanism by which cells maintain genomic stability,was awarded the Nobel Prize in Chemistry in 2015.DNA damage repair pathways mainly include:base-excision repair(BER),nucleotide excision repair(NER),mis-match repair(MMR),homologous recombination(HR)and non-homologous end joining(NHEJ).They play an important role in the repair of DNA damage such as single-strand break(SSB)or double-strand break(DSB).DNA damage repair defects are closely related to tumorigenesis and development and is also an important target for tumor therapy.Poly-ADP-ribose polymerase(PARP)and breast canc-er susceptibility gene BRCA1/2 and others in the DNA damage repair pathways have synthetic lethality effects.It makes PARP inhibitor(PARPi)be the first and currently the only commercially available syn-thetic lethal target drug for tumor therapy.PARPi has good efficacy in the treatment of ovarian cancer and a variety of solid tumors,which make the research and development of synthetic lethal target drugs related to DNA damage repair and DDR pathway become a hot spot.Other targets under research mainly in-clude:ataxia telangiectasia-mutated protein(ATM),ataxia telangiectasia and RAD3 related protein(ATR),DNA-dependent protein kinase catalytic subunit(DNA-PKcs),checkpoint kinasel(CHK1),Checkpoint kinase 2(CHK2),mitogen-preventing protein kinase WEE 1,etc.The combination of PARPi with other DDR target drugs,anti-angiogenesis drugs or immune checkpoint inhibitors may be-come effective means and development prospect to overcome PARPi resistance and improve the therapeu-tic effect.Here we review the key molecules and potential tumor therapeutic targets in DNA damage re-pair and related DDR pathways,and the research on synthetic lethal targets and their application and prospect in ovarian cancer.We aim to provide guidance for basic research and clinical application.

Objective:To analyze clinical features, short-term efficacy and side effects of salvage re-irradiation therapy for patients with locally recurrent esophageal cancer after definitive chemoradiotherapy, to investigate the prognostic factors of re-irradiation with precise radiotherapy techniques.Methods:A retrospective analysis was performed on patients with locally recurrent esophageal squamous cell carcinoma after definitive chemoradiotherapy treated in the Fourth Hospital of Hebei Medical University from January 2008 to December 2016. The patients underwent re-irradiation therapy (re-RT) or re-irradiation therapy concurrent chemotherapy (re-CCRT). The main observation index was after-recurrence survival (ARS), which was calculated by Kaplan-Meier method for survival analysis. Univariate analysis was conducted by log-rank test, and multivariate analysis was performed by Cox regression model.Results:A total of 109 patients were included, with a median age of 66 years (43-89 years), and a median follow-up time of 120.8 months (79.0-176.5 months). The objective response rates (ORR) and dysphagia improvement rates (DIR) in all patients were 64.2% and 63.0%, respectively. The median ARS and 1-, 3-, 5-, 8-year survival rates in all patients were 7.8 months and 32.1%, 9.2%, 7.3% and 2.3%, respectively. The median ARS and 1-, 3-, 5-years survival rates were 10.8 months and 45.9%, 13.5%, 10.8% for patients with time to recurrence (TTR) ≥24 months, significantly longer than those of 5.7 months and 25.0%, 6.9%, 5.6% for patients with TTR<24 months ( χ2=7.99, P=0.005). The median ARS in groups with re-irradiation dose of ≤50 Gy,>50-54 Gy, and>54 Gy groups were 5.7, 10.0 and 8.1 months, respectively ( χ2=6.94, P=0.031). The 1-, 3- and 5-year survival rates were 30.4%, 5.1%, and 3.8% for re-RT versus 36.7%, 20.0%, and 16.7% for re-CCRT ( χ2=2.12, P=0.145). Multivariate analysis showed that TTR ( HR=0.607, 95% CI=0.372-0.991, P=0.046) and lesion length ( HR=0.603, 95% CI=0.371-0.982, P=0.042) were the independent factors for ARS. There was no significant difference in ≥2 grade pneumonitis and 2-3 grade radiation esophagitis between the re-RT and re-CCRT groups ( χ2=0.25, P=0.619; χ2=0.51, P=0.808). The morbidity of ≥2 grade myelosuppression in the re-RT group was significantly lower than that in the re-CCRT group (3.7% vs. 36.7%, χ2=18.15, P<0.001). Conclusions:Precise re-irradiation therapy for patients with locally recurrent esophageal cancer after definitive chemoradiotherapy can alleviate dysphagia, but ARS remains poor. Re-irradiation dose range from>50-54 Gy may be suitable for locally relapse patients as salvage treatment. Patients with TTR≥24 months and lesion length ≤5 cm obtain favorable prognosis.

Objective:To observe the clinical efficacy and action mechanism of Jujing Decoction(JJD)in the treatment of as-thenoteratozoospermia(ATZ)by comparing JJD with combined administration of the antioxidant stress drug and sperm energy metabo-lism agent.Methods:According to the inclusion criteria,we enrolled 67 male patients with ATZ in this randomized controlled clini-cal study and treated them by oral administration of JJD(the JJD group,n=34)or natural vitamin E combined with L-carnitine solu-tion(the positive control group,n=33),both for 12 weeks.We collected the semen parameters,sperm DNA fragmentation index(DFI),sperm mitochondrial membrane potential(MMP),seminal plasma reactive oxygen species(ROS)and superoxide dismutase(SOD)levels from the patients,observed the ultrastructure of sperm mitochondria under the transmission electron microscope(TEM)before and after treatment,and analyzed the clinical efficacy and action mechanism of JJD by comparing the data obtained between the two groups.Results:Treatment and follow-up were completed in 60 of the cases,30 in the JJD and 30 in the positive control group.The total rate of clinical effectiveness was significantly higher in the JJD than in the positive control group(76.8％vs 43.3％,P＜0.05).Compared with the baseline,the percentages of progressively motile sperm(PMS)and morphologically normal sperm(MNS),DFI and MMP were significantly improved(P＜0.05),the level of seminal plasma ROS decreased(P＞0.05),and that of SOD re-markably increased(P＜0.05)after treatment with JJD;PMS,MNS,DFI and MMP were also improved(P＞0.05),seminal plas-ma ROS decreased(P＞0.05)and SOD increased(P＜0.05)in the positive controls after medication.In comparison with the posi-tive controls,the patients treated with JJD showed even more significant improvement in PMS([29.37±14.56]％vs[42.68±15.86]％,P＜0.05),MNS([1.84±1.32]％vs[3.66±1.72％]％,P＜0.05),DFI([32.66±5.23]％vs[16.61±4.20]％,P＜0.05)and MMP([46.47±9.48]％vs[61.79±8.61]％,P＜0.05),ROS([7.08±0.51]vs[5.06±0.52]μmol/L,P＞0.05),and SOD([100.65±10.59]vs[139.05±14.71]U/ml,P＜0.05).TEM revealed significantly improved ultrastructure of sperm mitochondria after treatment with JJD.No serious adverse reactions were observed in either group dur-ing follow-up.Conclusion:JJD,superior to natural vitamin E and L-carnitine oral solution,can safely and effectively increase the percentages of PMS and MNS,MMP and the level of seminal plasma SOD,reduce sperm DFI and seminal plasma ROS,and improve the ultrastructure of sperm mitochondria in patients with ATZ.The underlying mechanism of action may be related to its ability of im-proving the structure and function of sperm mitochondria via antioxidant stress.

Objective To analyze the cerebral blood flow changes in patients with newly diagnosed untreated early-onset depression(EOD),using three-dimensional pseudo-continuous arterial spin labeling(3D-pCASL),and to explore its relationship with clinical phenotypes.Methods The Hamilton Depression Scale(HAMD),Childhood Trauma Questionnaire(CTQ)scores,3D T1WI,and 3D-pCASL brain images of 65 untreated EOD patients and 55 healthy volunteers(HC group)were collected.SPM 12 and DPABI_V7.0 software were used to preprocess and analyze the whole brain images in two groups.Xjview software was used to analyze the value of cerebral blood flow(CBF)at the whole brain level of the two groups,and SPSS 25.0 software was used to evaluate the correlation of CBF values with HAMD scores and CTQ scores.Results Compared with the HC group,the CBF of the EOD group was reduced significantly[P＜0.05,cluster size＞50,false discovery rate(FDR)correction]in the right opercular inferior frontal gyrus(t=5.89),right temporo-parieto-occipital(TPO)region(t=6.49),and blood perfusion increased significantly(P＜0.05,cluster size＞50,FDR correction)in the left superior frontal gyrus(t=5.31)and left insular lobe(t=4.70).Conclusion The proportion of EOD patients with childhood trauma experience is relatively large.EOD patients have both reduced areas and increased areas in cerebral perfusion.The CBF value of the right TPO area is negatively correlated with HAMD scores;The CBF value of the left superior frontal gyrus is positively correlated with the total score of CTQ and the index of physical neglect score in CTQ,which is different from the result of studies that do not distinguish between early-onset and late-onset depression.

Objective To investigate the application value of indobufen combined with clopidogrel in elderly patients with coronary heart disease after percutaneous coronary intervention(PCI)with aspirin contraindications.Methods Elderly patients with coronary heart disease with aspirin contraindications were selected as study subjects and divided into 2 groups by random number table method.The control group was given oral clopidogrel bisulfate tablet 75 mg,qd;the treatment group was additionally given oral indobufen tablet 200 mg,qd,and both groups were treated for 3 months.Cardiac function indexes,coagulation-fibrinolytic system indexes,platelet function indexes,vascular endothelial function indexes and microcirculation function indexes were compared between the two groups before and after treatment,and the incidence of MACE and adverse drug reactions were analyzed.Results In this trial,39 cases in both the treatment group and the control group were included in the statistical analysis.The total effective rate of treatment group and control group were 94.87％and 79.49％,respectively,and the total effective rate of treatment group were higher than that of control group(P＜0.05).After treatment,the left ventricular ejection fraction(LVEF)of treatment group and control group were(57.13±3.16)％and(55.65±3.01)％,and the left ventricular end-diastolic volume index(LVEDVI)were(61.29±3.46)and(63.78±3.12)mL·m-2,respectively;the cardiac index were(3.68±0.31)and(3.41±0.28)L·min-1·m-2,and the stroke output index(SVI)were(57.37±2.57)and(55.29±2.74)mL·m-2,respectively;plasminogen activator inhibitor-1(PAI-1)levels were(46.29±4.18)and(49.37±5.24)ng·mL-1;antithrombin Ⅲ(AT-Ⅲ)levels were(131.04±10.65)％and(120.95±9.73)％,respectively;tissue plasminogen activator(t-PA)levels were(0.54±0.09)and(0.46±0.10)U·mL-1;fibrinogen(FIB)levels were(3.52±0.61)and(4.03±0.59)g·L-1,respectively;PT were(15.43±0.65)and(14.92±0.57)s,respectively.Compared with control group,the above indexes in treatment group were statistically significant(all P＜0.05).In the treatment group,there were 1 case of malignant arrhythmia in the cardiovascular adverse event(MACE),and in the control group,there were 2 cases of acute myocardial infarction,3 cases of malignant arrhythmia,2 cases of target vessel revascularization,and 1 case of acute thrombus in the stent.The incidence of MACE in the treatment group and the control group were 2.56％and 20.51％,respectively;the difference were statistically significant(P＜0.05).Conclusion In elderly patients with coronary heart disease contraindicated with aspirin after PCI,indobufen combined with clopidogrel can improve the cardiac function and microcirculation function,improve coagulation and fibrinolysis function,reduce vascular endothelial function injury,and reduce the incidence of MACE.
