Based on commonly used acupoints in the clinical acupuncture treatment of functional dyspepsia （FD）， this study systematically analyzes the therapeutic differences and synergistic effects between local and distal point selection. It also examines the suitability of primary acupoint selection for different FD subtypes， postprandial distress syndrome （PDS） and epigastric pain syndrome （EPS）. The findings suggest that a combination of local and distal acupoints may be more appropriate as primary points for PDS， whereas local acupoints alone may be more suitable for EPS. Additionally， the study explores the impact of various factors， such as stimulation techniques， needling order， intensity or stimulation parameters， and depth， on the efficacy of acupuncture. It concludes that the intrinsic properties of acupoints are the primary determinants of therapeutic direction. Other factors mainly influence the magnitude rather than the direction of the effect. Future research may further investigate how different acupoint combinations， local versus distal， affect the treatment outcomes of FD subtypes， providing new insights for clinical acupuncture prescriptions.

Methamphetamine abuse is a major public health problem in the world,and in recent years,methamphetamine is also the most abused synthetic drug in China.The neurotoxic or addiction mechanism of methamphetamine has not been fully clarified,and there is still a lack of specific withdrawal methods and drugs for methamphetamine abuse.Mitochondria are not on-ly the organelles to which methamphetamine directly produces toxic effects,but also participate in regulating the neurotoxic damage process of methamphetamine.Mitochondrial quality is the regulatory basis for maintaining mitochondrial homeostasis and is regulated by three main mechanisms,which are mitochon-drial biogenesis,mitochondrial dynamic,and mitophagy.This review summarizes the research progress of mitochondrial quality control in methamphetamine-induced neurotoxicity,which may provide theoretical support for further research on the mechanism of methamphetamine neurotoxicity and development the mito-chondria-targeting drugs.

Objective To investigate the efficacy and safety of a new type of self-made bone drill applied to percutaneous transforaminal endoscopic discectomy for L5/S1 intervertebral disc herniation.Methods The clinical data of 52 patients with L5/S1 intervertebral disc herniation admitted to our hospital were retrospectively analyzed.All patients underwent percutaneous transforaminal endoscopic discectomy,with a new type of self-made bone drill for foraminoplasty during the surgery.The surgical conditions and occurrence of complications were recorded.The pain of patients before surgery,3 days after surgery,3 months after surgery,6 months after surgery,and 1 year after surgery was assessed by visual analogue scale(VAS);and the neurological function improvement before and after surgery was evaluated by Oswestry disability index(ODI).Results All patients underwent successful surgery without serious complications or recurrence after surgery.The VAS and ODI scores of patients 3 days,3 months,6 months,and 1 year after surgery were significantly lower than those before surgery(P<0.05).Conclusion The self-made new bone drill can significantly improve the efficiency of foraminoplasty and ensure surgical safety,with satisfactory early clinical effect.

Objective:To understand the real feelings of oncology nurses in using arm port, so as to provide basis for taking targeted intervention measures to reduce the problems in the process of nurses using arm port and continuously improve the quality of intravenous therapy.Methods:Using the purposive sampling method, a total of 13 nurses from Oncology Department of Beijing Hospital were selected for in-depth interviews from October to November 2023, and the data were analyzed using Colaizzi's 7-step analysis method.Results:Three themes were extracted, including positive experiences (high sense of security and benefit), growth and reflection and negative experiences (concerns about unknown risks, tension and stress) .Conclusions:As a relatively safe route of administration, arm port is worthy of further promotion and application. There are many concerns among oncology nurses during the use of arm port. It is recommended that medical staff jointly strengthen comprehensive evaluations of patients and managers provide corresponding training and guidance for weak links to alleviate nurses' concerns during the use of arm port, in order to provide patients with higher quality intravenous treatment nursing services.

Objective To explore the clinical features,diagnostic methods,and treatment strategies for severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)encephalitis confirmed through cerebrospinal fluid(CSF)analysis.Methods The clinical data of patients diagnosed with SARS-CoV-2 encephalitis through CSF analysis in the Neurology Intensive Care Unit of the First Affiliated Hospital of Nanchang University from March 2022 to March 2023 were collected.Additionally,the relevant literature published in both domestic and international databases was analyzed and synthesized.Results The main neurological manifestations of five cases included decreased consciousness(5/5),psychiatric disorder(2/5),seizures(2/5),quadriplegia(1/5),and headaches(1/5).Two cases had abnormal brain magnetic resonance imaging(MRI)changes,involving the temporal lobe,insular lobe,thalamus,hippocampus,and pons.Additionally,CSF analysis showed mildly elevated protein levels in two cases.Next-generation sequencing(NGS)of the CSF identified SARS-CoV-2 in all five cases(sequence:41-1620),and human herpesvirus 1 in one case(sequence:21).The treatment regimen for all cases included antiviral therapy,three were additionally treated with glucocorticoids and one received immunoglobulin therapy.All cases achieved a favorable outcome(mRS:0-2).Conclusion SARS-CoV-2 has the potential to induce encephalitis/meningitis due to its neurotropic nature.The consideration of this condition is warranted in patients with relevant epidemiological history and symptoms related to the central nervous system.CSF NGS serves as a valuable tool for early diagnosis,while active antiviral therapy and immunotherapy may improve patient outcomes.

Objective To establish an ideal modeling method for diarrhea predominant irritable bowel syndrome(IBS-D)with anxiely and depression in rats,and to provide a basis for the clinical study of IBS-D.Methods 60 rats were used in this study.(1)At first,20 rats were randomly divided into blank,3%acetic acid enema,4%acetic acid enema,and 5%acetic acid enema groups.After the modeling and observation period,the diarrhea status and the degree of colon injury caused by different modeling concentrations were observed by diarrhea related index and colon histopathology.(2)After the optimal modeling concentration was assessed,40 rats were randomly divided into control(a),acetic acid enema(b),acetic acid+binding(c),and acetic acid+binding+tail clip(d)groups and correspondingly treated for 8 days.After the treatments,the general condition,diarrhea-related index,open field test(OFT)score,and colonic histopathology of rats were evaluated.Results(1)Compared with the blank group,the fecal trait score of 4%acetic acid enema group was increased on days 1 to 3 after intervention(P＜0.001),and gradually decreased on days 4 to 7 after intervention.After 1 week,there was no significant difference between the fecal trait score and that of the blank group(P＞0.05).Body weight was lower(P＜0.01),fecal water content was higher(P＜0.001).Compared with blank group,body weight of the 5%acetic acid enema group was decreased(P＜0.001),the fecal trait score and diarrhea index were increased(P＜0.01).No significant difference was found between 3%acetic acid enema and blank groups.The pathological colon tissue showed that,compared with the blank group,the mucosal structure of the 4%acetic acid enema group was complete with a small amount of inflammatory cell infiltration,and the pathological tissue score showed no significant difference(P＞0.05),whereas the 5%acetic acid enema had a medium to large amount of inflammatory cell infiltration,and the pathological tissue score was increased(P＜0.01).(2)Compared with group a,group b had lower body weight(P＜0.001),and higher fecal trait score,fecal water content and diarrhea index(P＜0.01).Compared with a and b groups,the body weight of c and d groups was lower(P＜0.001),the fecal traits score,fecal water content,and diarrhea index were increased(P＜0.01),and the colon running time was decreased(P＜0.01).Compared with group c,Fecal water content in group D was higher(P＜0.001).In the OFT score,compared with a and b groups,the OFT distance,standing times,and upright times in c and d groups were lower(P＜0.05).Compared with c,the OFT distance,standing times,and upright times in d group were lower(P＜0.05).The pathological tissue of colon showed that the mucosal structure of the four groups was complete,and there were different degrees of inflammatory cell infiltration.The pathological tissue scores of groups c and d were higher than those of groups a and b(P＜0.05).Conclusions The 4%acetic acid concentration is appropriate for IBS-D modeling.After superposition and binding,the IBS-D diarrhea and internal hypersensitivity characteristic state can be better simulated.After superposition of a tail clip,the IBS-D model of liver stagnation and spleen deficiency can be established successfully.

Objective:To investigate the relationship between sarcopenia and the long-term prognosis of elderly patients with locally advanced colorectal cancer.Methods:A retrospective analysis was conducted on clinical data from 205 elderly colorectal cancer patients aged 70 years and above who underwent radical resection with TNM staging of stage Ⅱ to Ⅲ at Beijing Hospital between January 2014 and December 2018.The study utilized abdominal CT scans taken within 30 days before surgery to measure the skeletal muscle area(SMA)of the 3rd lumbar vertebrae cross-section.Sarcopenia was defined as a skeletal muscle index(SMI) of ≤52.4 cm 2/m 2 in men and ≤38.5 cm 2/m 2 in women(SMI=SMA/height 2).A comparison was made between the clinical and pathological conditions of patients with and without sarcopenia in the two groups, with an analysis of the impact of sarcopenia on the long-term prognosis of elderly postoperative colorectal cancer patients. Results:Among the 205 patients assessed, 63.4%(130/205)were diagnosed with sarcopenia.The group with sarcopenia had a higher percentage of individuals aged 80 years and older( χ2=6.420, P=0.011)compared to those without sarcopenia.Additionally, this group had a lower proportion of overweight or obese patients( χ2=9.366, P=0.009), fewer patients who underwent adjuvant chemotherapy, and a lower 5-year disease-free survival rate post-surgery( χ2=6.257, 7.347, P=0.012, 0.007).Kaplan-Meier analysis indicated that disease-free survival rate was better in elderly patients with locally advanced colorectal cancer who did not have sarcopenia compared to those with sarcopenia(Log-rank χ2=6.919, P=0.009).Moreover, in elderly patients without sarcopenia, those who received adjuvant chemotherapy had a more favorable disease-free survival outcome than those who did not receive such treatment(Log-rank χ2=4.745, P=0.029).Multifactorial Cox regression analysis showed that TNM stage Ⅲ( HR=1.634, 95% CI: 1.110-2.404, P=0.013)and the presence of sarcopenia( HR=1.509, 95% CI: 1.017-2.238, P=0.041)were significant factors influencing the poor long-term prognosis of elderly patients with locally advanced colorectal cancer. Conclusions:Sarcopenia is associated with aging and body mass index, and has been found to be a significant factor in the long-term prognosis of elderly colorectal cancer patients.Those with sarcopenia tend to have a poorer prognosis, while those without may experience benefits from adjuvant chemotherapy.

Objective To conduct a detailed clinical phenotypic analysis and gene mutation detection on an au-tosomal dominant Van der Hoeve syndrome family,and to identify the pathogenic gene mutation sites of the family and the impact of the mutation on gene coding.Methods Clinical data including medical history,physical examina-tion and auxiliary examination were collected and peripheral blood samples were collected from the Van der Hoeve syndrome families.Exome sequencing and Sanger sequencing were performed on 22 family members.The data were analyzed using bioinformatics software.Results The family had a total of 5 generations,with each generation expe-riencing consecutive illnesses.Each generation of men and women could suffer from the disease,which conformed to the characteristics of autosomal dominant inheritance.The 12 patients in this family were all born with blue sclera and short stature.8 patients had a history of fractures and could heal normally.3 patients were considering hearing loss caused by Van der Hoeve syndrome.12 patients had a base deletion(c.1128delT)in exon 17 of the COL1A1 gene,causing a change in the amino acid coding after position 376 and ending the amino acid coding prematurely at position 539.10 asymptomatic individuals in this family didn't had this mutation.Conclusion The patient of this family was identified as Van der Hoeve syndrome caused by c.1128 delT mutation.

Purpose To explore the value of contrast-enhanced ultrasound(CEUS)in the differential diagnosis of gallbladder polypoid lesions(GPLs)(diameter≥10 mm).Materials and Methods A prospective enrollment of 229 patients with GPLs who underwent cholecystectomy in 17 hospitals from December 1 2021 to June 30 2024 was conducted to analyze the relationship between general data,conventional ultrasound,CEUS characteristics and the nature of GPLs.Multivariate Logistic regression was employed to identify independent risk factors for neoplastic polyps,the differential diagnostic value of different indicators was compared.Results Among 229 patients with GPLs,there were 108 cases of cholesterol polyps,102 cases of adenoma and 19 cases of gallbladder cancer.Age(Z=-4.476,P<0.001),polyp number(χ2=15.561,P<0.001),diameter(Z=-8.149,P<0.001),echogenicity(χ2=9.241,P=0.010),vascularity(χ2=23.107,P<0.001),enhancement intensity(χ2=47.610,P<0.001),enhancement pattern(χ2=6.468,P=0.011),vascular type(χ2=84.470,P<0.001),integrity of gallbladder wall(χ2=7.662,P=0.006)and stalk width(Z=-9.831,P<0.001)between cholesterol polyps and neoplastic polyps were statistically significant.Age,location,diameter,echogenicity,enhancement pattern,vascular type and stalk width between adenoma and gallbladder cancer were statistically significant(Z=-4.333,-3.902,-5.042,all P<0.05).Multivariate Logistic regression analysis showed that hyper-enhancement,branched vascular type and stalk width were independent risk factors for neoplastic polyps(OR=4.563,5.770,3.075,all P<0.001).The combination of independent risk factors was better than single factor and diameter in the differential diagnosis of cholesterol polyps and neoplastic polyps(all P<0.01).Conclusion CEUS can effectively identify the nature of GPLs and provide a valuable imaging reference for the selection of treatment methods.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
