Objective:To investigate the efficacy and safety of sintilimab combined with the SOX regimen for adjuvant treatment of stage Ⅲgastric cancer after D2 radical resection and to provide a reference for individualized clinical treatment.Methods:The clinical data of 245 pa-tients with stage III gastric cancer who underwent D2 radical resection at the 940th Hospital of the Joint Support Force of the People's Liber-ation Army from June 2019 to May 2022 were retrospectively analyzed.The 180 patients who received only the SOX regimen were desig-nated the control group,and the 65 patients who received sintilimab combined with the SOX regimen were designated the experimental group.The 3-year disease-free survival(DFS)rate,overall survival(OS)rate,and adverse reactions among the two groups and different sub-groups(HER-2 positive,dMMR,CPS≥5)were compared.Results:The 3-year DFS(81.5%vs.59.4%)and OS(84.6%vs.70.6%)rates in the experimental group were significantly higher than those in the control group(both P<0.05).Group analysis showed that in patients with CPS≥5,the 3-year DFS(91.5%vs.67.0%)and OS(95.7%vs.71.6%)rates within the experimental group were significantly better than those in the control group(both P<0.05).Intra-group analysis within the experimental group showed that the 3-year DFS rate(91.5%vs.55.6%)and OS rate(95.7%vs.55.6%)of patients with CPS≥5 were significantly better than those of patients with CPS<5(both P<0.05).The overall and grade≥3 incidences of liver and kidney function damage,thyroid dysfunction,colitis,pneumonia,and rash in the experimental group were higher than those in the control group(all P<0.05),while the differences in other adverse reactions,including leukopenia were not statistic-ally significant(all P>0.05).Conclusions:Sintilimab combined with the SOX regimen can significantly improve 3-year DFS and OS rates in pa-tients with stage Ⅲ gastric cancer after surgery,especially in the CPS≥5 subgroup,with significant benefits and controllable safety.

Objective:To summarize the clinical manifestations, diagnosis and treatment of a family with hereditary sensory and autonomic neuropathy (HSAN) caused by the SPTLC1 gene variation and to review the literature. Methods:Case summary.The clinical manifestations, neuroelectrophysiology, genetic examination, treatment and follow-up of a family with autosomal dominant HSAN diagnosed at the Department of Neurology, Beijing Children′s Hospital in March 2024 were summarized.At the same time, related English and Chinese literatures were searched from CNKI, Wanfang and PubMed databases from their establishment to July 2024, with " serine palmitoyltransferase long-chain base subunits 1", " hereditary sensory and autonomic neuropathy", " SPTLC1" and " HSAN1" taken as key words.Results:The proband was a 11-year-and-2-month-old boy, who developed limited bending at the age of 7.The patient had ankle pain and knee bending during walking, and limited movement.He could neither jump on one foot nor bend down to pick up things from the ground, but there was no obvious sensory and autonomic nervous function abnormalities.His parents had no abnormal clinical manifestations.Neuroelectrophysiology showed peripheral nerve damage, and family whole exon sequencing revealed a maternal heterozygous missense variation of the SPTLC1 gene c.1015G>A, p.A339T(maternal origin, reported).Further maternal neuroelectrophysiology examination and sphingomyelin analysis confirmed the diagnosis of HSAN1A.The proband wore orthopedic insoles, and the proband and his mother took L-serine orally for 8 months.During the follow up, the proband reported slight improvement in muscle strength, and no adverse reactions were found.Two Chinese and thirteen English case reports on autosomal dominant HSAN caused by the SPTLC1 gene variation were retrieved.Twenty cases had complete clinical data.Therefore, a total of 22 cases, including the above-mentioned two patients, were analyzed.Except for patients whose age at diagnosis is unknown and who are deceased, the age at diagnosis ranged from 7 to 93 years.The 66.7%(14/21) cases were childhood-onset.The first clinical symptoms were mainly gait abnormalities, easy falls, sensory disorders and ulcers.Foot deformity, and autonomic neuropathy were detected in 53.3% (8/15), and 31.6% (6/19) cases, respectively, 15.8% (3/19) of the cases had amputation.Only 1 case was treated with L-serine, who showed partial relief of clinical symptoms, but electromyography was not significantly improved.Fifteen cases received neuroelectrophysiological testing, and 78.6%(11/14) of the patients showed sensory and motor neurogenic injuries.All the gene variations reported previously were missense mutations, and the high frequency variation was p. C133T/W. Conclusions:This study is helpful to improve the understanding of the clinical characteristics of HSAN1A caused by the SPTLC1 gene.Oral L-serine supplementation may benefit patients and gene detection promotes diagnosis confirmation and early treatment.

Objective To explore the correlation of traditional Chinese medicine(TCM)syndrome elements with language function and activities of daily living(ADL)in patients suffering post-stroke aphasia(PSA).Methods Ninety-eight PSA patients hospitalized at the College of Rehabilitation Medicine,Fujian University of Traditional Chinese Medicine from April 2023 to April 2024 were selected.The language function,TCM syndrome elements,and their correlations were analyzed.Results(1)Among PSA patients,males outnumbered females.PSA patients exhibited different performances on various aphasia-related scales,with language impairments mainly concentrated in naming and spontaneous speech.(2)The distribution of TCM syndrome elements varied in PSA patients with different age groups.In the age group＜50 years old,qi obstruction(100.00%),phlegm syndrome(100.00%),and dampness syndrome(100.00%)were predominant.In the age group of 50-59 years old,phlegm syndrome(100.00%)and yang hyperactivity syndrome(96.30%)were predominant.In the age group of 60-69 years old,phlegm syndrome(100.00%)and yang hyperactivity syndrome(96.15%)were also predominant.In the age group of 70-79 years old,qi deficiency syndrome(100.00%)was predominant.In the age group of 80-89 years old,syndromes such as qi insecurity,qi obstruction,qi deficiency,phlegm,yang hyperactivity,blood stasis,wind stirring,and blood cold were concentrated(all 100.00%).However,there were no statistically significant differences in the distribution of TCM syndrome elements among various age groups(P＞0.05).(3)The distribution of deficiency and excess syndrome elements varied in PSA patients with different genders.Among deficiency syndrome elements,yang hyperactivity,qi deficiency,and yin deficiency were predominant in males,while yang hyperactivity,qi deficiency,and blood deficiency were predominant in females.Among excess syndrome elements,phlegm syndrome,qi obstruction,and dampness syndrome were predominant in males,while phlegm syndrome,qi obstruction,and qi stagnation syndrome were predominant in females.However,there were no statistically significant differences in the distribution of deficiency and excess syndrome elements between genders(P＞0.05).(4)After controlling the factors of age group and gender,partial correlation analysis of syndrome elements and language function showed that among the disease-location syndrome elements,spontaneous naming(r=-0.588,P=0.027)and sematic cued naming(r=-0.558,P=0.038)in the Boston Naming Test(BNT)were negatively correlated with the large intestine;among the disease-nature syndrome elements,BNT sematic cued naming(r=0.821,P＜0.001)was positively correlated with qi sinking,while BNT spontaneous naming was negatively correlated with blood heat(r=-0.544,P=0.044)and was positively correlated with fluid depletion(r=0.860,P=0.028);BNT recognitive naming was positively correlated with external wind(r=0.966,P=0.034);errors in BNT sematic cued naming were negatively correlated with qi sinking(r=-0.540,P=0.005);the Modified Barthel Index(MBI)was positively correlated with essence deficiency(r=0.572,P=0.021).Conclusion The TCM syndrome elements of phlegm,qi block,yang hyperactivity,and qi deficiency are commonly seen in PSA patients.There is a certain correlation of language function and ADL with TCM syndrome elements in PSA patients.

Objective:To establish a high-performance liquid chromatography (HPLC) characteristic spectrum of Radix Actinidiae Chinensis decoction pieces, standard decoction and formula granules; To simultaneously determine the contents of index components; To study the transfer law of formula granules based on the extraction amount, content of Catechin and characteristic spectrum of standard decoction.Methods:15 batches of Radix Actinidiae Chinensis decoction pieces were collected, the standard decoction was prepared, and the extraction amount was measured. The HPLC fingerprints of decoction pieces, standard decoction and formula granules were established, and the characteristic peaks were calibrated and attributed. The content of Catechins in decoction pieces, standard decoction and formula granules was measured, and the transfer rate law was calculated. The yield rate, the common peak transmission number of fingerprints, the content and the transfer rate were the main evaluation indexes, and the law of the transmission of the magnitude value was analyzed.Results:The paste yield of 15 batches of Radix Actinidiae Chinensis standard decoction ranged from 3.9%-6.3%. A total of 4 characteristic peaks were calibrated in the feature map, and peak 2 was identified as Protocatechuic acid and peak 4 as Catechin; 6 characteristic peaks were detected in Actinidia chinensis Planchon decoction pieces, standard decoction and formula granules, and their relative retention times were all within the specified range. The content of Catechins in Radix Actinidiae Chinensis decoction pieces was 0.4%-1.4%, which was 3.8%-4.9% in formula granules. The transfer rate of decoction pieces-standard decoction was 13.6%-38.3%, and the decoction-formula granules was 15.5%-21.2%.Conclusions:The mass transfer between Radix Actinidiae Chinensis decoction pieces, standard decoction and formula granules has a good migration. The formula granules also have a good correlation and consistency with the standard decoction, which indicating that the preparation process of Radix Actinidiae Chinensis is reasonable and feasible.

Objective:To analyze the genetic sequences of two patients with a rare Ael blood subgroup.Methods:Two female patients undergoing treatment respectively for adenomyoma of the uterus and gastritis at the Second Affiliated Hospital, Yuying Children′s Hospital of Wenzhou Medical University in June 2019 and September 2020 were selected as the study subjects. Their Ael subtypes were identified with a saline tube agglutination assay and absorption-emission assay. Sequence of the ABO gene Ael subtypes was determined by the Sanger method. The impact of genetic variants on the structural stability of N-acetylgalactosaminyl transferase (GTA) was analyzed with PyMOL software by constructing a structure predicted model. Results:Both patients were determined as Ael blood subgroup. Sequencing result of patient 1 was ABO* O.01.02/ ABO* O.01.02, which has resulted in a p. Thr88Profs*31 amino acid substitution. The sequencing result of patient 2 was ABO* Ael.06/ ABO* O.01.02, in which c. 425C>T and c. 467C>T variants in exon 7 have led to p. Met142Thr and p. Pro156Leu substitutions. Prediction of the protein model speculated that the p. Met142Thr not only can change the binding of GTA protein with water molecules, but also the local hydrogen bond network of GTA, which may lead to decreased enzymatic activity. By contrast, the p. Pro156Leu variant has trivial effect on the structural stability of GTA. Conclusion:The molecular structure of Ael subtypes can be diverse. The genotypes of the two patients have been respectively determined as ABO* O.01.02/ ABO* O.01.02 with a G261 deletion and ABO* Ael.06/ ABO* O.01.02.

Tumor cells use glycolysis to provide material and energy under hypoxic conditions to meet the energy requirements for rapid growth and proliferation， namely the Warburg effect. Even under aerobic conditions， tumor cells mainly rely on glycolysis to provide energy. Therefore， glucose transporter protein 1（GLUT1）， which is involved in the process of glucose metabolism， plays an important role in tumorigenesis， development and drug resistance， and is considered to be one of the important targets in the treatment of malignant tumors. In recent years， research on tumor glucose metabolism has gradually become a hot spot. It has been shown that various factors are involved in the regulation of tumor energy metabolism， among which the role of GLUT1 is the most critical. In this paper， the authors reviewed the latest research progress of GLUT1-targeted traditional Chinese medicine（TCM） active ingredient nano-delivery system in tumor therapy， aiming to reveal the feasibility and effectiveness of this system in the delivery of chemotherapeutic drugs. The GLUT1-targeted TCM active ingredient nano-delivery system can overcome the bottleneck of the traditional targeting strategy as well as the high-permeability long retention（EPR） effect. In summary， the authors believe that the GLUT1-targeted TCM active ingredient nano-delivery system provides a new strategy for targeted treatment of tumors and has a broad application prospect in tumor prevention and treatment.
