Hepatocellular carcinoma （HCC） with biliary duct tumor thrombus （BDTT） is currently not common in clinical practice and is easily misdiagnosed， and previously， it was often considered an advanced stage of the disease with a poor prognosis， making its treatment challenging. However， in-depth studies in recent years have gradually deepened our understanding of this disease， leading to significant changes in diagnostic and treatment concepts. Currently， comprehensive treatment， mainly surgery， is used for treatment， but there is still controversy over the selection of clinical treatment strategies. This article provides a detailed discussion on surgical methods and prognosis， in order to provide a reference for clinical treatment options.

Yttrium-90 selective internal radiation therapy (⁹⁰Y-SIRT) is a treatment technique that delivers radioactive microspheres precisely to the arterial vascular bed of neoplasms, utilizing beta radiation to administer a high local dose of radiation to the neoplasm tissues.

This article systematically reviews the development history and clinical application status of ⁹⁰Y-SIRT in the treatment of liver cancer, and looks forward to future development directions.

Organoid technology， a rapidly advancing three-dimensional （3D） cell culture platform， can closely mimic the microarchitecture and functions of human digestive organs， effectively overcoming the limitations of conventional two-dimensional cell models and animal experiments. By systematically summarizing the distinctive strengths of organoid technology in simulating digestive physiological and pathological states， constructing digestive system disease models， enabling high-throughput drug screening， and facilitating personalized treatment， this review explored the potential applications of organoids in identifying active components of traditional Chinese medicine （TCM） formulas， evaluating in vitro pharmacokinetics and toxicological parameters， and investigating multi-target synergistic mechanisms. By integrating cutting-edge engineering technologies， organoids are expected to provide a more scientific research platform for TCM， accelerate the modernization of its mechanistic studies， and enhance its scientific value and global impact.

By consulting the ancient and modern literature， the textual research of Pharbitidis Semen has been conducted to clarify the name， origin， distribution of production areas， quality specification， harvesting， processing and so on， so as to provide reference for the development and utilization of the relevant famous classical formulas. Through textual research， it can be seen that Pharbitidis Semen was first published in Mingyi Bielu（《名医别录》）， and all dynasties have taken Qianniuzi as the correct name. Based on the original research， the main source of Pharbitidis Semen used in previous dynasties is the dried mature seeds of Pharbitis nil， which is consistent in ancient and modern times. The white Pharbitidis Semen appearing in Compendium of Materia Medica（《本草纲目》） from Ming dynasty is similar to the present P. purpurea. It is produced all over the country， and the quality is better if the particles are full and free of impurities. In ancient times， the harvesting time was mostly in the September. Now it is autumn. The fruits are ripe and harvested， dried to remove impurities for standby. In ancient times， the processing methods of Pharbitidis Semen were mainly wine steaming， steaming and frying until half cooked and grinding the head and end. In modern times， they have been simplified to stir-frying method. The nature， taste， meridian tropism and their effects also change supplements with the deepening of practice. Before the Ming dynasty， they were all bitter， cold and toxic. In the Ming dynasty， there appeared the characteristics of pungent， hot and small poisonous. The efficacy has evolved from controlling low Qi， curing foot edema， removing wind toxin， and facilitating urination to facilitating water and defecation， eliminating phlegm and drinking， and eliminating accumulated insects. The main clinical contraindications are those with weak spleen and kidney， those with weak spleen and stomach， pregnant women， and should not be used with croton and croton cream. Based on the textual research， it is suggested that when developing the classic famous formula with Pharbitidis Semen as the main raw material in the future， it is clear that the source should be the dried mature seeds of Pharbitis nil（black product is its black-brown seeds， white product is its beige seeds）. The processing requirements indicated in the original formula are all processed according to the requirements， and the raw product is recommended to be used as medicine if not specified.

Objective To investigate the association between four single nucleotide polymorphisms(SNP)(rs9340 in MAPK1,rs14804 in NRAS,rs712 and rs7973450 in KRAS)in the 3'UTR of ERK1/2 signaling pathway-related genes and non-small cell lung cancer(NSCLC).Methods A total of 478 NSCLC patients and 480 healthy controls were enrolled in this study.Four SNPs were genotyped by using TaqMan assays.The association between the four SNPs and NSCLC was analyzed.Results The distribution frequency difference of the allele of rs9340 was statistically significant between the control group and the non-small cell squamous cell carcinoma(SCC)group(P = 0.009),suggesting that the G allele of rs9340 may be a protective factor for non-small cell lung squamous cell carcinoma(OR = 0.67,95%CI:0.50～0.91).In addition,in the<50 years age group,the distribution frequency difference of the allele of rs9340 was statistically significant between the control group and the NSCLC group(P = 5.07×10-4),indicating that the G allele of rs9340 may be a protective factor for NSCLC(OR = 0.46,95%CI:0.29～0.72).Conclusion The SNP rs9340 in MAPK1 may be associated with the risk of NSCLC.

BACKGROUND:The renin-angiotensin system plays a key role in the occurrence and development of hypertension,in which angiotensin(1-7)has antihypertensive effect and reversely regulates the adverse effects of angiotensin Ⅱ.Exercise rehabilitation therapy is an important non-pharmaceutical means to prevent and treat hypertension;however,whether angiotensin(1-7)and exercise have a synergistic effect is not yet clear. OBJECTIVE:To explore the effect of angiotensin(1-7)supplementation combined with exercise therapy on cardiac remodeling in rats with renal hypertension and to investigate the possible mechanism of angiotensin(1-7)and its receptor signal axis. METHODS:Sixty male Sprague-Dawley rats were selected,of which 12 rats were randomly selected as normotensive group and the remaining 48 rats were used to make animal models of renal hypertension using two-kidney one-clip method and were then randomly divided into hypertension control group,hypertension exercise group,angiotensin(1-7)group and combined treatment group.One week after successful modeling,different interventions were given(for a period of 6 weeks)as follows:the hypertension exercise group was subjected to a running training on an electric treadmill,the angiotensin(1-7)group was perfused with angiotensin(1-7)by implanting Alzet microosmotic pump subcutaneously on the back of the rats,and the combined treatment group was perfused with angiotensin(1-7)after running training,while the normotensive group and hypertension control group were caged quietly.At 48 hours after the last training session,the tail artery blood pressure was measured with a non-invasive sphygmomanometer;the heart structure and function were detected by echocardiography;the left ventricular myocardium was taken for histopathological observation by hematoxylin-eosin and Masson staining,and the cardiomyocyte cross-sectional area and collagen volume fraction were obtained by image analysis software as markers of myocardial hypertrophy and fibrosis,respectively;the content of angiotensin(1-7)in the heart was detected by high performance liquid chromatography;the mRNA expression of cardiac embryonic genes,atrial natriuretic peptide and β-myosin heavy chain,was detected by real-time fluorescence quantitative PCR;and the protein expression of cardiac Mas receptor,angiotensin Ⅱ type 2 receptor and endothelial nitric oxide synthase was measured by western blot assay. RESULTS AND CONCLUSION:Compared with the normotensive group,blood pressure increased(P<0.05),cardiac function had no significant changes(P>0.05),cardiomyocyte cross-sectional area and collagen volume fraction increased(P<0.05),mRNA expression of atrial natriuretic peptide and β-myosin heavy chain was upregulated(P<0.05),angiotensin(1-7)content and protein expression of Mas receptor,angiotensin Ⅱ type 2 receptor and endothelial nitric oxide synthase was downregulated(P<0.05)in the hypertension control group.Compared with the hypertension control group,blood pressure decreased(P<0.05),cardiac function improved(P<0.05),collagen volume fraction decreased(P<0.05),cardiomyocyte cross-sectional area and angiotensin(1-7)content showed no significant changes(P>0.05),mRNA expression of atrial natriuretic peptide and β-myosin heavy chain was downregulated(P<0.05),and the protein expression of Mas receptor,angiotensin Ⅱ type 2 receptor and endothelial nitric oxide synthase was upregulated(P<0.05)in the hypertension exercise group;except for an increase in myocardial angiotensin(1-7)content(P<0.05),other parameters had no statistical significance(P>0.05)in the hypertension angiotensin(1-7)group.Compared with the hypertension exercise group,blood pressure decreased(P<0.05),cardiomyocyte cross-sectional area and cardiac function had no significant changes(P>0.05),collagen volume fraction decreased(P<0.05),angiotensin(1-7)content increased(P<0.05),mRNA expression of atrial natriuretic peptide and β-myosin heavy chain was downregulated(P<0.05),and the protein expression of Mas receptor,angiotensin Ⅱ type 2 receptor and endothelial nitric oxide synthase was upregulated(P<0.05)in the combined treatment group.To conclude,supplementation of angiotensin(1-7)alone cannot improve cardiac remodeling in rats with renal hypertension,but it can enhance the efficacy of exercise.The mechanism is related to the improvement of angiotensin(1-7)receptor deficiency and restoration of its signaling pathway function.

ObjectiveTo analyse the current implementation status of Chinese herbal medicine （CHM） placebo and systematically evaluate the placebo effect in randomised controlled trials （RCTs） of traditional Chinese medicine （TCM） for the treatment of functional dyspepsia （FD）. MethodsA combination of medical subject terms and free words was used to search six databases， including PubMed， EMBASE， Cochrane Library， Web of Science， China National Knowledge Infrastructure， and Wanfang， for RCTs with CHM placebo group for FD published from January 31st， 1994 to September 30th， 2023. The dosage forms， composition， and methodological quality were collected and evaluated. The quality of the included articles was evaluated by Cochrane risk of bias assessment tool， and meta-analysis was performed on the CHM placebo response rate of patients with FD， and subgroup analysis and meta-regression was performed according to diagnostic criteria， efficacy criteria， duration of treatment， type of placebo， whether it contained active ingredient， and whether it evaluated placebo effects. ResultsA total of 34 publications were included involving 5046 participants， of which 2221 FD patients received CHM placebo treatment. Granules were the predominant placebo preparation， accounting for 71% （24/34）； 32.35% （11/34） of the studies added real CHM to the placebo， and only 12 （35%） of the studies described appearance， odour， and taste. The placebo response rate in FD patients in the placebo group was 41% （95% CI： 0.35 to 0.47； P＜0.01， I² = 87%）； there was significant difference between groups with different diagnostic criteria and different treatment durations （P＜0.05 or P＜0.01）， but there was no significant difference between the different efficacy evaluation criteria， the different placebo preparation， the presence of a low-dose active ingredient， and the presence or absence of placebo assessment （P＞0.05）. ConclusionThere was a significant CHM placebo effect in patients with FD， with granules as the main preparation of placebop. Different diagnostic criteria and different treatment times may affect the response rate of patients， and the addition of low-dose real medicine to the CHM placebos has not been seen to have an effect on the response rate. Clinical investigators have not paid enough attention to placebos， and there is a lack of uniform standards and norms for the preparation and evaluation of CHM placebos.

Objective To assess the efficacy and safety of ascending aorta banding technique combined with typeⅠhybrid aortic arch repair for the aortic arch diseases. Methods The clinical data of patients undergoing ascending aorta banding technique combined with type Ⅰ hybrid arch repair for aortic arch diseases from March 2019 to March 2022 in Beijing Anzhen Hospital were retrospectively analyzed. The technical success, perioperative complications and follow-up results were evaluated. Results A total of 44 patients were collected, including 35 males and 9 females, with a median age of 63.0 (57.5, 64.6) years. The average EuroSCORE Ⅱ score was 8.4%±0.7%. The technical success rate was 100.0%. All patients did not have retrograde type A aortic dissection and endoleaks. One patient died of multiple organ failure 5 days after operation, the in-hospital mortality rate was 2.3%, and the remaining 43 patients survived and were discharged from hospital. The median follow-up period was 14.5 (6-42) months with a follow-up rate of 100.0%. One patient with spinal cord injury died 2 years after hospital discharge. One patient underwent thoracic endovascular aortic repair at postoperative 3 months due to new entry tears near to the distal end of the stent. Conclusion Ascending aorta banding combined with typeⅠhybrid arch repair for the aortic arch diseases does not need cardio-pulmonary bypass. Ascending aorta banding technique strengthens the proximal anchoring area of the stent to avoid risks such as retrograde type A dissection, endoleak and migration. The operation owns small trauma, rapid recovery, low mortality and a low rate of reintervention, which may be considered as a safe and effective choice in the treatment of the elderly, high-risk patients with complex complications.

This study was designed to investigate the effect of Sijunzi decoction(SJZD)on the expression of inflammatory factors and autophagic proteins in the hippocampus of senescence-accelerated mouse prone 8(SAMP8)mice and its mechanism.SAMR1 mice were used as control group,and 32 SAMP8 mice were divided into model group,donepezil group,SJZD low and SJZD high dose treatment groups.Y-maze experiment was performed to detect changes in mouse memory function;the expression of NF-κB was detected by immunohistochemistry;the levels of TNF-α,IL-1β,IL-6 were detected by ELISA;the expression of A[3,caspse-1,beclin-1 and LC3-Ⅱproteins in hippocampal tissue were detected by Western blotting.Compared with the control group,the model group mice showed a decrease in total number of entries and alternations,an elevation in the levels of TNF-α,IL-1β,IL-6,Aβ protein and caspse-1 protein,and downregulation in the expression of beclin-1 and LC3-Ⅱ proteins.Both donepezil and SJZD(low-dose group and high-dose group)can reverse these changes in model mice.In conclusion,the mechanism of SJZD in treating Alzheimer's disease may relate to the correction of central hippocampal inflammatory factors and autophagy dysfunction.
