The purpose of this paper is to explore the decoction and dosing methods of rhubarb root and rhizome in classical prescriptions and to provide a reference basis for the clinical use of rhubarb root and rhizome. By collating the relevant classical prescriptions of rhubarb root and rhizome in Shanghan Lun and Jingui Yaolüe, the relationship between its decoction and dosing methods and the syndrome was analyzed. The decoction of rhubarb root and rhizome in classical prescriptions can be divided into three categories: simultaneous decoction, decoction later, and other methods (impregnation in Mafei decoction, decoction with water from the well spring first taken in the morning, and pills). If it enters the blood level or wants to slow down, rhubarb root and rhizome should be decocted at the same time with other drugs. If it enters the qi level and wants to speed up, rhubarb root and rhizome should be decocted later. If it wants to upwardly move, rhubarb root and rhizome should be immersed in Mafei decoction. If it wants to suppress liver yang, rhubarb root and rhizome should be decocted with water from the well spring first taken in the morning. If the disease is prolonged, rhubarb root and rhizome should be taken in pill form. The dosing methods of rhubarb root and rhizome can be divided into five categories: draught, twice, three times, before meals, and unspecified. For acute and serious illnesses with excess of pathogenic qi and adequate vital qi, we choose draught. For gastrointestinal diseases, we choose to take the medicine twice. For achieving a moderate and long-lasting effect, we choose to take the medicine three times. If the disease is located in the lower part of the heart and abdomen, we choose to take it before meals. The use of rhubarb root and rhizome in clinical practice requires the selection of the appropriate decoction and dosing methods according to the location of the disease, the severity of the disease, the patient′s constitution, and the condition after taking the medicine.

Due to the wide variety and varying quality of medical wound dressings, as well as the current lack of unified national or industry standards for regulation, this paper proposes a research strategy for establishing a quality evaluation system for medical wound dressings‌. By developing a technical roadmap, this strategy clarifies the process flow and key points in the quality evaluation process, establishes evaluation methods for various types of medical wound dressings, and addresses important issues such as how to determine key performance indicators based on product characteristics and how to research and validate test methods for key items. This provides a detailed and feasible research strategy and evaluation method for medical wound dressing manufacturers, testing institutions, and regulatory authorities. It reduces the difficulty and cost of quality evaluation for medical wound dressings and has certain significance in standardizing and improving their quality level, ensuring their safety and effectiveness, and serving the quality and safety regulation of medical devices.‌.

Objective:To explore the association between macrosomia delivery history and adverse pregnancy outcomes in subsequent pregnancies under different stratification of gestational weight gain(GWG).Methods:A retrospective study was conducted on 500 multiparous women with a history of macrosomia delivery who gave birth at The Second Hospital of Jilin University from January 2020 to November 2023.Meanwhile,1500 multiparous women without a history of delivering macrosomic infants were selected as the control group through 1∶3 matc-hing based on age(±1 year).The differences in general characteristics,GWG,and pregnancy outcomes be-tween the two groups were compared.According to the appropriate GWG values recommended by Chinese health industry standards,pregnant women in both groups were classified into insufficient GWG,appropriate GWG,and excessive GWG.Multivariate Logistic regression analysis was used to compare the relationship be-tween a history of macrosomia delivery and adverse pregnancy outcomes under different GWG stratifications.Re-sults:The History of macrosomia group had significantly higher rates of excessive GWG(50.60%vs.48.13%),incidence of gestational diabetes mellitus(GDM)(23.40%vs.17.07%),rate of cesarean section(60.20%vs.45.33%),and rate of macrosomia(26.60%vs.7.87%)compared to the control group(P<0.05).Multivariate Logistic regression analysis showed that a history of macrosomia delivery was an independent risk factor for GDM,cesarean section,and macrosomia in subsequent pregnancies(aOR>1,P<0.05).Stratified analysis based on GWG revealed that,compared with the control group,regardless of the GWG status,the risk of cesare-an section and macrosomia was higher in women with a history of macrosomia delivery(aOR>1,P<0.05).Mo-reover,for those with a history of macrosomia delivery and excessive weight gain during pregnancy,the risk of preeclampsia(aOR 3.167,P<0.05)and GDM(aOR 1.661,P<0.05)was significantly increased.When the GWG was appropriate for pregnant women with a history of macrosomia delivery,there was no significant correla-tion between a history of macrosomia delivery and preeclampsia or GDM(P>0.05).Conclusions:A history of macrosomia delivery increased the risk of multiple adverse pregnancy outcomes,such as GDM,cesarean section,and macrosomia.For multiparous women at different GWG levels,the risk of cesarean section and macrosomia was significantly increased in those with a history of macrosomia delivery.When GWG was appropriate,a history of macrosomia delivery was not found to be an independent risk factor for preeclampsia and GDM.

Colorectal cancer (CRC) represents a significant global health challenge as a common malignancy of the digestive tract. The involvement of B vitamins—specifically folic acid (B9), riboflavin (B2), pyridoxine (B6), and cobalamin (B12)—is crucial in metabolic processes by mediating the transfer of one-carbon (1C) units, which plays a fundamental role in cellular functions and tumor growth. 1C metabolism is involved in synthesis of proteins, lipids, nucleic acids, and other cofactors. 1C metabolism, intertwined with the metabolism of other nutrients, forms complex pathways where B vitamins act as precursors or coenzymes, influencing the production of various intermediates. These vitamins, as essential nutrients, are implicated to varying the pathogenesis and progression of colorectal cancer such as epigenetics. Furthermore, 1C metabolism affects tumor cell fate through multiple aspects including nucleotide synthesis, redox homeostasis, and the interaction with gut microbiota. Given these roles, understanding and monitoring B vitamin levels and their metabolic pathways are essential for colorectal cancer prevention and management. This approach not only helps in reducing tumor-related mortality but also opens new avenues for research into CRC mechanisms and potential therapeutic strategies.

Objective To compare the efficacy of MRI-transrectal ultrasound(TRUS)software fusion-guided biopsy and cognitive fusion-guided biopsy for detecting prostate cancer(PC).Methods Data of 120 patients with suspected PC(127 lesions)who underwent transperineal prostate biopsy with 2-3 times of target biopsy(TB)and 10 times of system biopsy were retrospectively analyzed.According to TB guidance methods,73 cases(78 lesions)received MRI-TRUS software fusion-guided biopsy were classified into group A,and 47 cases(49 lesions)received cognitive fusion-guided biopsy were classified into group B.The positive rate of PC,clinic significant PC(csPC)and PC in different sized lesions by TB were compared between groups,and the positive rate of PC between 2 or 3 times TB was also compared within each group.Results The positive rate of PC and csPC detected by TB was 55.13%(43/78)and 39.74%(31/78)in group A,53.06%(26/49)and 34.69%(17/49)in group B,respectively,no significant difference was found(all P＞0.05).The positive rate of PC in lesions with the maximum diameter≤10 mm detected by TB in group A was higher than that in group B(P＜0.05),but no significant difference of lesions with the maximum diameter＞10 mm and＜15 mm nor≥15 mm was found between groups(all P＞0.05).No significant difference of positive rate of PC was found between 2 and 3 times TB in group A(P＞0.05),while positive rate of PC of 3 times TB was significantly higher than that of 2 times TB in group B(P＜0.05).Conclusion MRI-TRUS software fusion-guided biopsy had positive rate of PC and csPC similar to that of cognitive fusion-guided biopsy,but was helpful for reducing times of TB and increasing detecting rate for lesions with the maximum diameter≤10 mm.

Objective:To analyze the genetic variants of two consanguineous Chinese pedigrees affected with Hereditary prokallikrein (PK) and High molecular weight kininogen (HMWK) deficiency and explore their molecular pathogenesis.Methods:A PK deficiency pedigree (10 individuals from 4 generations) and a HMWK deficiency pedigree (6 individuals from 3 generations) which were admitted to the First Affiliated Hospital of Wenzhou Medical University on December 3, 2021 and June 16, 2022, respectively were selected as the study subjects. Clinical data of the two pedigrees were collected, and the related coagulation indexes of the probands and their family members were determined. Genomic DNA of the two pedigrees was extracted from peripheral blood samples. This study was approved by the First Affiliated Hospital of Wenzhou Medical University (Ethics No. KY2022-R193).Results:The plasma PK activity of proband A, a 29-year-old female, and her brother were extremely low (< 1.0%). Proband B was a 66-year-old male with extremely low plasma HMWK activity (< 1.0%). Genetic sequencing revealed that the proband A and her brother had both harbored a homozygous c. 417_418insCATTCTTA (p.Arg140Hisfs*3) insertional variant in exon 5 of the KLKB1 gene, with her grandmother, maternal grandmother, father, mother, sister and son all carrying heterozygous insertion variant, and her ancestor father and husband are both wild-type. Proband B had harbored a homozygous c. 460C>A (p.Pro154Thr) missense variant in exon 4 of the KNG1 gene, and his son carries a heterozygous missense variant. All other members of the pedigree are wild type. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variants were respectively rated as pathogenic (PVS1+ PM2_Supporting+ PM4) and likely pathogenic (PS4+ PM2_Supporting+ PP3+ PP4). Conclusion:The c. 417_418insCATTCTTA (p.Arg140Hisfs*3) variant of the KLKB1 gene and the c. 460C>A (p.Pro154Thr) variant of the KNG1 gene probably underlay the decreased PK and HMWK activities in the two pedigrees, respectively.

Diabetes mellitus type 2 might cause mild cognitive impairment in its advanced stages,potentially progressing to dementia.Diabetic cognitive impairment(DCI)stands as a chronic complication of diabetes mellitus,with its underlying pathogenesis still remaining elusive.Research has revealed that gut microbiota dysbiosis influenced the central nervous system through the"microbiota-gut-brain axis",thereby contributing to the progression of cognitive impairment.Therefore,the regulation of gut microbiota emerges as a promising approach to the prevention and treatment of DCI.This article comprehensively reviews the mechanisms through which gut microbiota influences DCI.Furthermore,it delves into experimental studies exploring targeted therapies for gut microbiota,including probiotics,fecal microbiota transplantation,dietary and nutrient interventions,as well as traditional Chinese medicine.These studies not only address diabetes-related cognitive impairment but also consider aspects such as glycolipid metabolism and inflammation.The insights gleaned from these studies provide valuable guidance for the clinical application of gut microbiota-targeted intervention in DCI.

Diabetes mellitus and its consequences have gained increased attention with the incidence rate rising.Diabetic cognitive impairment (DCI), a neurological consequence of diabetes mellitus, has shown a significant increase in recent years, and its related mechanisms need to be elucidated. Short-chain fatty acids (SCFAs), which are metabolites of dietary fiber fermented by gut microbiota and play a significant role in the "microbial-gut-brain axis", have become a popular research topic in recent years for their link to diabetes mellitus and brain function. Therefore, it is important to explore the relationship between SCFAs and DCI. This review summarized the changing characteristics of SCFAs in diabetes mellitus, cognitive impairment and DCI populations, as well as the mechanisms of SCFAs in DCI, which include glucose-lipid metabolism, pathological protein aggregation, inflammation, and mitochondrial autophagy.Future studies should address the common pathophysiological mechanisms of diabetes mellitus and cognitive impairment, in order to explore the effects of different types and doses of SCFAs in DCI and the underlying mechanisms, so as to provide a theoretical basis for the prevention and treatment of the disease in the context of the "co-morbidity model" .
