Objective: To investigate the distribution of traditional Chinese medicine (TCM) syndromes and syndrome elements in lymphoma, as well as the correlation between TCM syndromes and Western clinical indicators, in order to analyze associations between TCM syndromes and these indicators. Methods: From January 2023 to May 2024, 216 patients with lymphoma who met the inclusion criteria in the Department of Hematology, Third People′s Hospital Affiliated to Fujian University of Traditional Chinese Medicine were enrolled. Four diagnostic methods were applied to perform TCM syndrome differentiation and extract syndrome elements. The correlations between various syndromes and blood test indicators of lactate dehydrogenase (LDH), β2-microglobulin (β2-MG), immunoglobulin G (IgG), immunoglobulin M (IgM), immunoglobulin A (IgA), white blood cell (WBC), hemoglobin (Hb), platelet count (PLT), neutrophil (NEUT), immunohistochemical markers of B-cell lymphoma-6 (BCL6), B-cell lymphoma-2 (BCL2), proto-oncogene MYC, and Ki67 protein expression, Ann Arbor staging, international prognostic index (IPI) score, bone marrow infiltration, concurrent infections during chemotherapy, and post-chemotherapy bone marrow suppression rate were analyzed. Results: Five TCM syndromes, ranked by frequency, were syndromes of yin deficiency with phlegm accumulation(41.67%), qi depression with phlegm obstruction(30.56%), cold-phlegm congelation and stagnation(12.96%), phlegm-blood stasis toxin(12.04%), and lingering pathogen due to deficient vital qi(2.77%). Yin deficiency(50.93%) and phlegm(45.37%) were the more prevalent syndrome elements. The TCM syndromes were correlated with β2-MG, PLT, MYC, BCL2/MYC, Ki67 protein expression, and bone marrow infiltration (P<0.05). No statistically significant differences were observed in Ann Arbor staging or IPI score across the syndromes. Compared to the syndrome of cold-phlegm congelation and stagnation, the syndrome of qi depression with phlegm obstruction exhibited higher levels of NEUT, MYC, BCL2/MYC, and Ki67 protein expression, as well as a higher rate of post-chemotherapy bone marrow suppression (P<0.05); the syndrome of phlegm-blood stasis toxin showed higher MYC and BCL2/MYC protein expression and a higher rate of post-chemotherapy bone marrow suppression rate (P<0.05); the syndrome of yin deficiency with phlegm accumulation demonstrated higher MYC and BCL2/MYC protein expression and bone marrow infiltration rates, whereas PLT level was lower (P<0.05); the syndrome of lingering pathogen due to deficient vital qi had higher MYC, BCL2/MYC, and Ki67 protein expression levels, as well as a higher rate of post-chemotherapy bone marrow suppression rate (P<0.05). Compared to the syndrome of qi depression with phlegm obstruction, the syndrome of phlegm-blood stasis toxin exhibited lower Ki67 protein expression (P<0.05); the syndrome of yin deficiency with phlegm accumulation had higher β2-MG level, bone marrow infiltration rate, and rate of concurrent infections during chemotherapy, whereas PLT and NEUT levels and the rate of post-chemotherapy bone marrow suppression rate were lower (P<0.05). Compared to the syndrome of phlegm-blood stasis toxin, the syndrome of yin deficiency with phlegm accumulation had higher β2-MG level, whereas NEUT and the rate of post-chemotherapy bone marrow suppression were lower(P<0.05); the syndrome of lingering pathogen due to deficient vital qi exhibited a higher Ki67 protein expression (P<0.05). Compared to the syndrome of yin deficiency with phlegm accumulation, the syndrome of lingering pathogen due to deficient vital qi also showed a higher Ki67 protein expression(P<0.05). Conclusion The syndrome of yin deficiency with phlegm accumulation is relatively common in lymphoma. There is a correlation between TCM syndromes and Western medicine clinical indicators. The presence of heat signs in the syndromes may indicate active disease and poor prognosis, while the presence of strong pathogenic factors and weak vital qi in the syndromes may indicate a severer chemotherapy-related bone marrow suppression.

Objective To investigate the influencing factors of unplanned rehospitalization within one year after surgery among adult renal transplant recipients. Methods The clinical data of 299 recipients who underwent renal transplant surgery in the Department of Organ Transplantation of the Affiliated Hospital of Guizhou Medical University from January 2020 to December 2022 were retrospectively analyzed. The recipients were divided into unplanned rehospitalization group and non-rehospitalization group based on whether they experienced unplanned rehospitalization within one year after surgery. Univariate analysis and binary Logistic regression analysis were performed to explore the influencing factors of unplanned rehospitalization within one year after renal transplantation. Results Among the 299 recipients, 102 experienced unplanned rehospitalization, with an incidence rate of 34.11%. Univariate analysis revealedstatistically significant differences were noted between the two groups in terms of gender, occupational status, preoperative underlying disease, rejection reactions, nosocomial infections, immunosuppressive medication regimens, serum creatinine, cystatin C, serum phosphorus, serum potassium, and initial hospitalization duration (P < 0.05). Binary Logistic regression analysis showed that having ≥3 kinds of preoperative underlying disease (OR=2.122, 95%CI, 1.198 to 3.759) and experiencing rejection reactions (OR=3.162, 95%CI, 1.217 to 8.218) were independent risk factors for unplanned rehospitalization within one year after renal transplantation (P < 0.05). Conclusion The rate of unplanned rehospitalization within one year after surgery is relatively high among adult renal transplant recipients. Having ≥3 preoperative underlying disease and experiencing rejection reactions are independent risk factors for unplanned rehospitalization within one year after surgery. Transplantation healthcare teams can develop corresponding strategies targeting these risk factors to reduce the rate of unplanned rehospitalization and alleviate the burden of disease.

Objective To investigate the epidemiological characteristics and mutation spectrum of monogenic diseases in Chinese population through a large-scale,multicenter carrier screening.Methods This study was conducted among a total of 33 104 participants(16 610 females)from 12 clinical centers across China.Carrier status for 223 genes was analyzed using high-throughput sequencing and different PCR methods.Results The overall combined carrier frequency was 55.58%for 197 autosomal genes and 1.84%for 26 X-linked genes in these participants.Among the 16 669 families,874 at-risk couples(5.24%)were identified.Specifically,584 couples(3.50%)were at risk for autosomal genes,306(1.84%)for X-linked genes,and 16 for both autosomal and X-linked genes.The most frequently detected autosomal at-risk genes included GJB2(autosomal recessive deafness type 1A,393 couples),HBA1/HBA2(α-thalassemia,36 couples),PAH(phenylketonuria,14 couples),and SMN1(spinal muscular atrophy,14 couples).The most frequently detected X-linked at-risk genes were G6PD(G6PD deficiency,236 couples),DMD(Duchenne muscular dystrophy,23 couples),and FMR1(fragile X syndrome,17 couples).After excluding GJB2 c.109G>A,the detection rate of at-risk couples was 3.91%(651/16 669),which was lowered to 1.72%(287/16 669)after further excluding G6PD.The theoretical incidence rate of severe monogenic birth defects was approximately 4.35‰(72.5/16 669).Screening for a battery of the top 22 most frequent genes in the at-risk couples could detect over 95%of at-risk couples,while screening for the top 54 genes further increased the detection rate to over 99%.Conclusion This study reveals the carrier frequencies of 223 monogenic genetic disorders in the Chinese population and provides evidence for carrier screening strategy development and panel design tailored to the Chinese population.In carrier testing,genetic counseling for specific genes or gene variants can be challenging,and the couples need to be informed of these difficulties before testing and provided with options for not screening these genes or gene variants.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Biliary fibrosis (BF) is the result of pathological repair of bile tract injury, characterized by thickening and sclerosis of the bile duct wall and progressive stricture of the lumen, which may ultimately lead to serious adverse outcomes such as biliary obstruction, biliary cirrhosis, liver failure, and hepatobiliary malignancies. Current research describes BF as a pathological feature of certain bile tract diseases, lacking a systematic summary of its etiology, pathophysiology, molecular mechanisms, and treatment. BF is a common but easily neglected disease state in biliary system, which may promote the development and progression of hepatobiliary diseases through abnormal repair mechanism after pathological biliary tract injury. Based on the latest research progress from both domestic and international perspectives, the authors review the concept, clinical manifestation, etiology, pathogenesis, and therapeutic strategies of BF to provide a reference for clinical physicians.

Objective To investigate the correlations of the expression levels of plasma long non-coding RNA plasmacytoma variant translocation 1 (LncRNA PVT1) and microRNA-143-3p (miR-143-3p) with disease activity and prognosis in patients with rheumatoid arthritis (RA). Methods A total of 129 RA patients admitted to our hospital from April 2021 to April 2023 were selected as disease group. According to the 28-joint disease activity scores (DAS28), the patients were divided into stable disease group (n=28), mildly active group (n=42), moderately active group (n=35), and severely active group (n=24). According to the prognosis of the patients after 6 months of treatment, they were divided into good prognosis group (n=88) and poor prognosis group (n=41), and 110 healthy people who underwent physical examinations in our hospital during the same period were included as control group. The expression levels of plasma LncRNA PVT1 and miR-143-3p were detected using quantitative real-time fluorescent polymerase chain reaction (qRT-PCR). The targeting relationship between LncRNA PVT1 and miR-143-3p was predicted using the Target Scan Human website. Multivariate Logistic regression analysis was conducted to explore the factors influencing the prognosis of RA patients. Receiver operating characteristic (ROC) curve was performed to assess the predictive value of plasma LncRNA PVT1 and miR-143-3p for the prognosis of RA patients. Results The plasma LncRNA PVT1 level in the disease group was higher than that in the control group, while the plasma miR-143-3p level was lower (P < 0.05). The plasma LncRNA PVT1 levels decreased sequentially in the severe activity, moderate activity, mild activity, and disease stable groups, while the plasma miR-143-3p levels increased sequentially (P < 0.05).The proportion of patients positive for human leukocyte antigen-DR4 (HLA-DR4), DAS28, and plasma LncRNA PVT1 expression level were higher in the poor prognosis group than in the good prognosis group, while the plasma miR-143-3p level was lower (P < 0.05). Plasma LncRNA PVT1, miR-143-3p expression, HLA-DR4 positivity, and DAS28 were factors influencing the prognosis of RA patients (P < 0.05). LncRNA PVT1 and miR-143-3p had targeted binding sites, and there was a negative correlation between them (P < 0.05). The area under the curve (AUC) for the combined prediction of plasma LncRNA PVT1 and miR-143-3p for prognosis of RA patients was 0.914, which was superior to the individual diagnosis of LncRNA PVT1 or miR-143-3p (Z=2.159, P=0.031; Z=2.108, P=0.035). The sensitivity and specificity of the combined diagnosis were 95.12% and 78.41%, respectively. Conclusion The plasma LncRNA PVT1 level gradually increases, while the plasma miR-143-3p level gradually decreases with increasing RA disease activity. The combined detection of the two biomarkers has high predictive value for the prognosis of RA patients.

Objective:To analyze the clinical characteristics, treatment, and prognosis of ectopic bronchogenic cysts in children.Methods:A retrospective analysis was conducted on the data including the clinical characteristics, auxiliary examination and treatment of 21 children with ectopic bronchogenic cysts diagnosed pathologically at Children′s Hospital Affiliated to Zhengzhou University from July 2015 to December 2023. There were 16 males and 5 females, with a male-female ratio of 3.2∶1, and the age ranged from 4 days to 8 years old (median age 2 years and 8 months).Results:Among the 21 cases of ectopic bronchogenic cysts, 11 cases were found in the pharynx, with symptoms including dyspnea (4 cases), snoring during sleep (3 cases), and choking on milk(4 cases).Ten cases were found in the head, neck or anterior chest, 5 of these cases had infection history, and 5 showed progressive mass growth.Imaging and endoscopy showed 9 patients underwent preoperative color ultrasonography revealed cystic masses with well-defined boundaries. CT examination was performed on 13 patients, which showed round or nearly round masses with homogeneous density, smooth margins, and regular cyst walls. CT attenuation values ranged from 2 to 52 Hounsfield Units (HU). Four cystic lesions were assessed via MRI, 3 cases demonstrated long T1 and long T2 signals, while 1 case had a slight short T1 and long T2 signal, with high signal intensity on fat-suppressed images. Eleven cases of pharyngopharyngeal cysts were examined by electronic nasopharyngoscopy. The cysts appeared as spherical or ovoid masses with smooth surfaces, close to or slightly light in color with the surrounding tissue, with one cyst presenting with a bluish blue in the oropharynx. All 11 pharyngeal cysts were excised using low-temperature plasma under general anesthesia and intubation assisted by a nasal endoscope. The cysts were pulled and excised as completely as possible.Ten cases of neck and anterior chest cysts were completely excised. Postoperative histopathology confirmed bronchogenic cyst. Twenty-one children were followed up postoperatively for 4 months to 7 years without recurrence, except for 1 patient who was lost to follow-up.Conclusions:Ectopic bronchogenic cysts are uncommon and lack of typical imaging and clinical features.Combination of ultrasonography, CT and MRI is recommended for cases occuered in neck and anterior chest, while electronic nasopharyngoscopy complements pharyngeal evaluations. Surgical intervention is the preferred treatment choice for this disease.

Objective:To analyze the levels of antibody to measles virus in cord blood of newborns in Ankang city, and provide reference for the development of measles prevention and control measures and strategies.Methods:From January to December, 2023, 1 058 pregnant women from 10 county-level general hospitals in Ankang city were recruited in this study. Neonatal umbilical cord blood samples were collected for detecting IgG antibody against measles with ELISA. SPSS 21.0 software was used to analyze the positive rate of antibody to measles virus and the influencing factors.Results:The overall positive rate of IgG antibody to measles virus was 89.22% (944/1 058), and the geometric mean concentration (GMC) was 570.26 mlU/ml. The positive rates of IgG antibody against measles virus in umbilical cord blood of neonates born to women aged ≤20, 21-25, 26-30, 31-35, and ≥36 years old were 91.07% (51/56), 90.27% (232/257), 89.54% (351/392), 88.12% (230/261), and 86.96% (80/92), respectively (χ 2=1.355, P=0.852). Multivariate logistic regression analysis showed that the positive rate of IgG antibody against measles virus in umbilical cord blood samples was higher in neonates with gestational age ≥37 weeks than in those with gestational age <37 weeks [OR (95%CI): 0.403 (0.262-0.622)]. Besides, the positive rate was also higher in newborns with a birth weight of 3.0-3.5 kg than in those with birth weight <3 kg or ≥3.5 kg [OR (95%CI): 0.868 (0.462-1.629), 1.765(1.087-2.865)]. Conclusions:The positive rate and the GMC of IgG antibody to measles virus in neonatal umbilical cord blood decrease with maternal age. It is recommended that women of childbearing age should receive supplementary immunization with measles-containing vaccine before pregnancy.

ObjectiveTo investigate the effect of rutin on the browning of 3T3-L1 preadipocytes and the mechanism. MethodCell counting kit-8 （CCK-8） assay was used to detect the effect of different concentration of rutin （3.125， 6.25， 12.5， 25， 50， 100， 200 μmol·L^-1） on 3T3-L1 cell activity， and Western blot to examine the effect of rutin （12.5， 25， 50 μmol·L^-1） on the expression of thermogenesis-associated proteins uncoupling protein 1 （UCP1）， PR domain containing 16 （PRDM16） and peroxisome proliferator-activated receptor γ coactivator-1α （PGC-1α） in adipocytes. After the optimal concentration of rutin was determined， the effect of rutin on lipid droplet formation in adipocytes was observed based on oil red O staining， and the expression of nuclear respiratory factor 1 （NRF1）， nuclear respiratory factor 2 （NRF2） and mitochondrial transcription factor A （TFAM）， which were the landmark proteins of mitochondrial biosynthesis， was detected by Western blot. ResultCompared with the blank group， 200 μmol·L^-1 rutin inhibited 3T3-L1 cell activity （P<0.01）. Compared with the blank group， at the concentration of 12.5， 25， 50 μmol·L^-1 rutin significantly promoted the expression of thermogenesis-associated proteins （UCP1， PRDM16， and PGC-1α） （P<0.01）， which was determined as the optimal concentration. Compared with the blank group， 50 μmol·L^-1 rutin significantly increased the immunofluorescence intensity of mitochondrial UCP1 protein in 3T3-L1 cells （P<0.01） and the expression of the markers of mitochondrial biosynthesis （NRF1， NRF2， and TFAM） （P<0.01）. In addition， 50 μmol·L^-1 rutin significantly inhibited lipid droplet formation of 3T3-L1 adipocytes （P<0.01）. ConclusionRutin inhibited lipid droplet deposition in 3T3-L1 adipocytes and increased the expression of thermogenesis-related proteins （UCP1， PRDM16， and PGC-1α） and markers of mitochondrial biosynthesis （NRF1， NRF2， and TFAM）， thereby inducing the browning of 3T3-L1 adipocytes. This lays a basis for the development of drugs that safely regulate the browning of white cells.
