This article systematically analyzed the historical evolution of the name， origin， harvesting and others of Longan Arillus by referring to the ancient and modern literature， in order to provide a foundation for developing famous classical formulas containing this herb. After textual research， it indicated that Longan Arillus was first recorded under the name of longan in Shennong Bencaojing of the Han dynasty. During the Ming and Qing dynasties， Longan Arillus gradually replaced longan as the standard name recorded in the materia medica， with additional aliases including Yizhi， Lizhinu and Yuanyan. The source of Longan Arillus used in the past dynasties was the arillus of the Sapindaceae plant Dimocarpus longan. The production regions recorded in the past dynasties were mainly Fujian， Guangdong， Guangxi， Hainan， Sichuan and others. Since the Qing dynasty， Longan Arillus produced in Fujian， Guangdong and Guangxi have been regarded as the finest and authentic varieties， with Fujian， Guangxi， and Guangdong remaining the primary authentic production areas today. In ancient times， the fruits were primarily harvested in August of the lunar calendar. However， modern longan cultivation typically involves harvesting ripe fruits during summer and autumn. Post-harvest processing involves removing moisture through sun-drying or baking before drying for medicinal use. Throughout history， processing methods have primarily focused on raw product， though techniques such as wine soaking and powdering have also been employed. Since modern times， it has been concluded that its quality is the best one with thick flesh， sweet taste， brownish-yellow color and tender texture. Longan Arillus possesses a sweet and warm nature， entering the heart and spleen meridians. Its primary functions are tonifying the heart and spleen， nourishing the blood and calming the spirit， which is consistent in ancient and modern times. Based on the textual research， it is suggested to use the arillus of D. longan when developing the famous classical formulas containing Longan Arillus. Processing methods should be selected according to the formula requirements， where no specific processing is indicated， the raw products is recommended for medicinal use.

Objectives: . The prognostic value of the pretreatment albumin-to-alkaline phosphatase ratio (AAPR) in head and neck cancer (HNC) remains uncertain. This meta-analysis aimed to evaluate the predictive role of AAPR for survival outcomes in patients with HNC. Methods: . A comprehensive search of the Cochrane Library, PubMed, and Embase databases was conducted to identify relevant studies published up to July 30, 2024. We included studies on AAPR and survival outcomes in HNC patients. Results: . Eight studies comprising 1,737 HNC patients were analyzed using random-effects models. Lower AAPR values were significantly correlated with worse overall survival (hazard ratio [HR], 2.08), progression-free survival (HR, 2.00), and disease-free survival (HR, 2.18). Sensitivity analyses confirmed the robustness of these results, with no significant publication bias detected. Conclusion . Our findings suggest that pretreatment AAPR could serve as a valuable and cost-effective prognostic indicator in HNC, potentially aiding clinicians in risk stratification and treatment decision-making. However, additional validation studies are warranted to confirm its clinical applicability.

Hepatic encephalopathy （HE） is a common complication of severe liver disease in the end stage， and it is urgently needed to improve the rate of effective treatment and clarify the pathogenesis of HE. The liver is a crucial hub for immune regulation， and disruption of immune homeostasis is a key factor in the pathological mechanisms of HE. As the main metabolites of intestinal flora， short-chain fatty acids （SCFAs） play a vital role in the biological processes of both innate and adaptive immunity and can regulate the proliferation and differentiation of immune cells maintain the homeostasis of intestinal microenvironment and the integrity of barrier function. Studies have shown that SCFAs participate in bidirectional and dynamic interactions with the liver-gut-brain axis through immunomodulatory pathways， thereby playing an important role in the diagnosis， treatment， and prognostic evaluation of HE. Starting from the immunoregulatory effect of SCFAs， this article summarizes and analyzes the crosstalk relationship between SCFAs and the liver-gut-brain axis and the significance of SCFAs in the diagnosis and treatment of HE， in order to provide new ideas for optimizing clinical prevention and treatment strategies.

Objective:To investigate the differences between high-frequency ultrasound-guided manual detorsion combined with surgery(MD+S)and surgery alone in the treatment of testicular torsion,and to provide some new evidence for the timely diagno-sis and treatment of the disease.Methods:We retrospectively analyzed the clinical data on 134 cases of unilateral testicular torsion within 48 hours treated in our hospital by MD+S or by surgery alone from January 2015 to May 2022.We statistically analyzed the age distribution,and duration and degrees of testicular torsion,followed by comparison between the two groups.Results:In the 134 ca-ses,the median age of onset was 15(13-19)years old,the median onset-to-visit time was 15(8-25)hours,and the median de-gree of torsion was 360°(180°-1080°).Of the total number of patients,21 underwent testicular excision and the other 113 were treated with the testis preserved,with no statistically significant difference in age distribution between the two groups(P＞0.05),and a higher rate of testis resection in those with longer duration and greater angle of torsion(P＜0.05).Totally,33 of the patients were assigned to the MD+S group and 101 to the surgery alone group.According to the actual clinical conditions and excluding those with torsion time longer than 24 hours and torsion angle greater than 720 °,28 of the patients underwent ultrasound-guided MD+S(with 1 case of testis resection,3.6％),and 68 received surgery alone(with 7 cases of testis resection,10.3％).The rate of testis resection was higher in the surgery alone than that in the MD+S group,but with no statistically significant difference between the two groups(P＞0.05),which was considered to be related to the small sample size in this study.Conclusion:The popularization of testicular torsion knowledge can shorten the onset-to-visit time,and reasonable manual detorsion before emergency surgery can reduce the rate of testis resection.

Objective To investigate the effects of ischemia time and storage periods on RNA quality in fresh-frozen breast cancer(BC)and esophageal cancer(EC)tissue samples in order to establish evidence-based protocols for biobank sample management.Methods The tumor(T)and paired normal(N)tissue samples from 6 cases of BC and 6 cases of EC were collected and cryopreserved in Biobank,Shantou Central Hospital.Mirror paraffin-embedded tissues were simultaneously prepared into sections for morphological analysis.The samples were divided into two groups of<15 min and 15-30 min according to ischemia time,and RNA quality was analyzed at 4 storage periods of 8-10 months(T1),14-16 months(T2),26-28 months(T3)and 38-40 months(T4).Results In 96 analyzed samples,93.8%(90/96)exhibited high quality(RIN≥6),with 89.6%(43/48)in BC and 97.9%(47/48)in EC.Significant differences in RIN were observed between BC group and EC group(8.050 vs.8.600,P=0.009).In EC group,RIN value was significantly negatively correlated with RNA yield(P<0.001).Moreover,RIN values of tumor-normal pairs exhibited markedly significant differences(7.550 vs.9.000,P<0.001).In contrast,no significant difference was detected in BC group(8.200 vs.7.700,P=0.348).Statistical analysis showed that RIN value was positively correlated with 28S/18S(P<0.001),but had no correlation with tumor content(P=0.676)and necrotic content(P=0.055).Neither ischemia time(<15 min vs.15-30 min:8.200 vs.8.300,P=0.932)nor storage periods(T1-T4:8.400,7.700,8.450,8.600,P=0.163)compromised RNA quality.Conclusion Organ origin and tissue type could influence RNA quality of fresh-frozen tissue samples.However,limited ischemia time(≤30 min)and long-term storage period(38-40 months)do not adversely affect RNA quality in fresh-frozen breast cancer and esophageal cancer tissue samples.

As an indispensable"energy factory"within cells,mitochondria efficiently convert chemical energy from food into ATP through oxidative phosphorylation,providing continuous energy support for va-rious cellular life activities.The functional homeostasis of mitochondria maintains the cell's energy sup-ply,redox balance,cell signaling,and metabolic regulation,thereby ensuring normal cell operation and the healthy survival of organisms.Processes such as mitophagy,mitochondrial fusion and fission,mito-chondrial transport,reactive oxygen species accumulation,and calcium signaling are involved in maintai-ning mitochondrial functional homeostasis.The degeneration of dopaminergic neurons in the striatum is the main pathological feature of Parkinson's Disease(PD).Dopaminergic neurons have unique polarized and extended structures with high bioenergetic demands,making them particularly susceptible to mito-chondrial dysfunction.When mitochondrial function is impaired,the energy supply to dopaminergic neu-rons is insufficient,leading to neuronal dysfunction and subsequently triggering a series of neurodegenera-tive diseases,including PD.The molecular basis of PD pathogenesis often involves abnormalities in pro-teins that maintain mitochondrial homeostasis.These proteins play crucial roles in sustaining mitochondri-al function,and any functional abnormalities or genetic mutations can lead to mitochondrial dysfunction,thereby inducing PD.This article provides a comprehensive review of recently reported abnormalities in proteins maintaining mitochondrial function and their association with the onset and progression of PD.The aim is to gain a deeper understanding of the functions of these proteins,their genetic mutations,and their relationship with the disease,providing valuable insights for the development of effective treatments and diagnostic biomarkers for PD.

This study is to explore the antibiofilm activity of tirapazamine(TPZ)against Salmonella and the mechanism of inhibiting biofilm formation.In this study,crystal violet staining was used to determine the effect of TPZ on the minimal biofilm inhibitory concentration(MBIC)of Salmonel-la and on the development stage of Salmonella biofilm.The effects of TPZ on bacteria and biofilm of Salmonella were observed by scanning electron microscope and fluorescence microscope.Phe-nol-sulfuric acid method,spectrophotometer and BCA method were used to detect the effects of the bacteria on the content of main extracellular matrix of Salmonella.The autocoagulation and hydro-phobicity of Salmonella were measured and their effects on the cell wall of Salmonella were meas-ured by AKP method.The result showed that the MBIC value of TPZ on Salmonella ATCC 14028 was 1.563 μmol/L,it had destructive effects on both Salmonella bacteria and mature biofilm structure,it inhibited the formation of early Salmonella biofilm in a concentration-dependent manner,and inhibited the synthesis and secretion of extracellular polymers in Salmonella biofilm.The autoagglutination ability,hydrophobicity and cell wall integrity of Salmonella were affected.To sum up,the TPZ may inhibit the formation of a large number of Salmonella biofilms in the early stage of biofilm development by affecting the extracellular polymer and cell agglutination a-bility,which is expected to be a potential candidate drug against biofilm infection and provide a new idea for finding alternative antibiotics.

Hepatic encephalopathy is a neuropsychiatric syndrome secondary to severe liver disease.Recent studies have shown that the development of hepatic encephalopathy is closely associated with bile acid/short-chain fatty acid metabolic disorder.As the core theory of traditional Chinese medicine,the theory of Yin and Yang provides a unique perspective for analyzing the association between bile acids/short-chain fatty acids and hepatic encephalopathy.Bile acids function like Yang,governing the free flow of Qi and assisting in metabolic processes,while short-chain fatty acids belong to Yin,maintaining internal stability and conservation,preserving the intestinal barrier,and combating inflammation and toxins.Bile acids and short-chain fatty acids constrain each other and are interdependent to regulate the dynamic equilibrium of the gut-liver-brain axis.On this basis,by regulating the metabolic imbalance of bile acids and short-chain fatty acids,it is expected to restore the dynamic balance of Yin and Yang in patients with hepatic encephalopathy under the synergistic intervention of traditional Chinese medicine and Western medicine.
