Objective:To analyze the epidemic characteristics of human brucellosis in Tangshan City, Hebei Province from 2016 to 2024, and to establish a prediction model for forecasting incidence of human brucellosis in Tangshan City from 2025 to 2028, so that to provide evidence for prevention and control strategies.Methods:The incidence data of human brucellosis in Tangshan City from 2016 to 2024 were collected. Brucella strains isolated from blood cultures of patients with acute brucellosis were identified.The onset time and demographic distributions of brucellosis were analyzed using descriptive epidemiological methods. Chi-square test was used for statistical analysis. Python software was used to establish a seasonal autoregressive integrated moving average model (SARIMA model) and predict the incidence of brucellosis in Tangshan City from 2025 to 2028. Results:From 2016 to 2024, a total of 2 446 cases of human brucellosis in Tangshan City were reported, with the highest incidence in 2016 (378 cases) and the lowest in 2022 (277 cases).Seasonal variation was observed, with 54.87%(1 342/2 446) occurring in spring and summer (March to July). The incidence rate of male was 5.28/100 000, which was significantly higher than that of female (1.94/100 000) ( χ2=554.96, P<0.001). The cases spanned all age groups, with the highest incidence among those aged 50 to 59 (30.25%(740/2 446)). Farmers engaged in cattle/sheep breeding accounting for 85.73% (2 097/2 446) of cases. A total of 236 blood samples were collected from patients with acute brucellosis, and 12 Brucella strains were isolated and identified as sheep type Ⅲ Brucella. The optimal model constructed was SARIMA (1, 0, 0) (1, 0, 1) 12, which was used to predict the incidence of human brucellosis in Tangshan City from 2025 to 2028. The results showed that the overall incidence was relatively stable, retaining the characteristic single annual peak. Conclusions:Human brucellosis in Tangshan City peaks in spring/summer and predominantly affects cattle/sheep farmers. The SARIMA (1, 0, 0) (1, 0, 1) 12 model effectively fits the epidemiological data of human brucellosis in Tangshan City well and enables reliable future trend predictions, supporting scientific and effective prevention and control work.

ObjectiveTo analyze the epidemiological trends and characteristics of brucellosis in humans (hereinafter referred to as brucellosis) in Tangshan City, Hebei Province from 2016 to 2023, and to provide a scientific basis for formulating brucellosis prevention and control strategies in the region. MethodsThe incidence data of human brucellosis in Tangshan City from 2016 to 2023 were collected from the China Disease Prevention and Control Information System. The diagnosis time, infection route, and clinical characteristics of the cases were obtained from the case investigation reports. Descriptive epidemiological methods were used to analyze the temporal, spatial, demographic distributions, and clinical characteristics of human brucellosis. Brucella species were identified using agglutination tests with bacterial suspension and A/M antigen-positive serum. ResultsA total of 2 193 cases of human brucellosis were confirmed and clinically diagnosed in Tangshan City from 2016 to 2023, with the peak incidence occured from March to August, and which exhibited distinct geographic distribution patterns. The highest incidence rate was found in people aged 60‒<70 years. The occupation of cases were primarily farmers. The incidence rate in males (528/100 000) was higher than that in females (184/100 000). All cases had confirmed exposure to infected animals or contaminated animal products. ConclusionThe epidemic of human brucellosis in Tangshan exhibited an overall steady downward trend from 2016 to 2023, except for a slight increase in 2016 and 2021, with the incidence rate controlled at 289/100 000‒335/100 000. The prevention and control situation of human brucellosis still remains severe, with the highest incidence rate in the eastern region of Tangshan, which are characterized by the breeding, slaughtering, and processing of cattle and sheep. Therefore, it it is necessary to enhance the prevention and control of human brucellosis among the personnel engaged in these industries in the eastern areas.

Dysregulated RNA splicing is a well-recognized characteristic of colorectal cancer (CRC); however, its intricacies remain obscure, partly due to challenges in profiling full-length transcript variants at the single-cell level. Here, we employ high-depth long-read scRNA-seq to define the full-length transcriptome of colorectal epithelial cells in 12 CRC patients, revealing extensive isoform diversities and splicing alterations. Cancer cells exhibited increased transcript complexity, with widespread 3'-UTR shortening and reduced intron retention. Distinct splicing regulation patterns were observed between intrinsic-consensus molecular subtypes (iCMS), with iCMS3 displaying even higher splicing factor activities and more pronounced 3'-UTR shortening. Furthermore, we revealed substantial shifts in isoform usage that result in alterations of protein sequences from the same gene with distinct carcinogenic effects during tumorigenesis of CRC. Allele-specific expression analysis revealed dominant mutant allele expression in key oncogenes and tumor suppressors. Moreover, mutated PPIG was linked to widespread splicing dysregulation, and functional validation experiments confirmed its critical role in modulating RNA splicing and tumor-associated processes. Our findings highlight the transcriptomic plasticity in CRC and suggest novel candidate targets for splicing-based therapeutic strategies.

OBJECTIVE:
To analyze the distribution and drug resistance of pathogens in oral mucositis associated with chemotherapy in hospitalized patients with malignant hematopathy, so as to provide scientific evidences for rational selection of antibiotics and infection prevention and control.
METHODS:
From July 2020 to June 2022, 167 patients with malignant hematopathy were treated with chemical drugs in the Department of Hematology, Hainan Hospital, and secretions from oral mucosal infected wounds were collected. VITEK2 COMPECT automatic microbial identification system (BioMerieux, France) and bacterial susceptibility card (BioMerieux) were used for bacterial identification and drug susceptibility tests.
RESULTS:
A total of 352 strains of pathogens were isolated from 167 patients, among which 220 strains of Gram-positive bacteria, 118 strains of Gram-negative bacteria and 14 strains of fungi, accounted for 62.50%, 33.52% and 3.98%, respectively. The Gram-positive bacteria was mainly Staphylococcus and Streptococcus, while Gram-negative bacteria was mainly Klebsiella and Proteus. The resistance of main Gram-positive bacteria to vancomycin, ciprofloxacin and gentamicin was low, and the resistance to penicillin, cefuroxime, ampicillin, cefotaxime, erythromycin and levofloxacin was high. The main Gram-negative bacteria had low resistance to gentamicin, imipenem and penicillin, but high resistance to levofloxacin, cefotaxime, cefuroxime, ampicillin and vancomycin. The clinical data of oral mucositis patients with oral ulcer (severe) and without oral ulcer (mild) were compared, and it was found that there were statistically significant differences in poor oral hygiene, diabetes, sleep duration less than 8 hours per night between two groups (P<0.05).
CONCLUSION
Gram-positive bacteria is the main pathogen of oral mucositis in patients with malignant hematopathy after chemotherapy. It is sensitive to glycopeptide antibiotics and aminoglycosides antibiotics. Poor oral hygiene, diabetes and sleep duration less than 8 hours per night are risk factors for oral mucositis with oral ulcer (severe).

In our retrospective cohort study, we aim to explore whether Azvudine modifies the risk of death in COVID-19 patients. It was conducted on the medical records of patients, consecutively admitted for COVID-19 pneumonia to two hospitals in Chongqing, China. Based on Azvudine treatment exposure, the patients were divided into Azvudine group and non-Azvudine group. We used 1:2 ratio propensity score matching (PSM) in our study to adjust for confounding factors and differences between Azvudine and non-Azvudine groups. There were 1072 patients included in our original cohort. With 1:2 ratio PSM, the Azvudine group included 195 patients and non-Azvudine group included 390 patients. The results showed that Azvudine treatment was associated with improved in-hospital mortality in overall population (OR 0.375, 95% CI 0.225-0.623, P < 0.001), severe subgroup (OR 0.239, 95% CI 0.107-0.535, P = 0.001), critical subgroup (OR 0.091, 95% CI 0.011-0.769, P = 0.028) in matched cohort with univariate analysis. And there was a significantly lower in-hospital mortality in overall population (11% vs. 24%, P<0.001), severe sub-group (10% vs. 32%, P < 0.001) and critical sub-group (5% vs. 34%, P = 0.017) in matched cohort. These results suggest Azvudine can reduce in-hospital mortality in overall COVID-19 patients, severe, and critical subgroup population.

Objective: To investigate the clinical characteristics and maternal and fetal prognosis of pregnant women with acute fatty liver of pregnancy (AFLP). Methods: The clinical data of 86 AFLP pregnant women admitted to the Third Affiliated Hospital of Guangzhou Medical University from September 2017 to August 2022 were collected, and their general data, clinical characteristics, laboratory tests and maternal and fetal outcomes were retrospectively analyzed. Results: (1) General information: the age of the 86 pregnant women with AFLP was (30.8±5.4) years, and the body mass index was (21.0±2.5) kg/m2. There were 50 primiparas (58.1%, 50/86) and 36 multiparas (41.9%, 36/86). There were 64 singleton pregnancies (74.4%, 64/86) and 22 twin pregnancies (25.6%, 22/86). (2) Clinical characteristics: the main complaints of AFLP pregnant women were gastrointestinal symptoms, including epigastric pain (68.6%, 59/86), nausea (47.7%, 41/86), anorexia (46.5%, 40/86), vomiting (39.5%, 34/86). The main non-gastrointestinal symptoms were jaundice of skin and/or scleral (54.7%, 47/86), edema (38.4%, 33/86), fatigue (19.8%, 17/86), bleeding tendency (16.3%, 14/86), polydipsia or polyuria (14.0%, 12/86), skin itching (8.1%, 7/86), and 17.4% (15/86) AFLP pregnant women had no obvious symptoms. (3) Laboratory tests: the incidence of liver and kidney dysfunction and abnormal coagulation function in AFLP pregnant women was high, and the levels of blood ammonia, lactate dehydrogenase and lactic acid were increased, and the levels of hemoglobin, platelet and albumin decreased. However, only 24 cases (27.9%, 24/86) of AFLP pregnant women showed fatty liver by imageology examination. (4) Pregnancy outcomes: ① AFLP pregnant women had a high incidence of pregnancy complications, mainly including renal insufficiency (95.3%, 82/86), preterm birth (46.5%, 40/86), hypertensive disorders in pregnancy (30.2%, 26/86), gestational diabetes mellitus (36.0%, 31/86), fetal distress (24.4%, 21/86), pulmonary infection (23.3%, 20/86), disseminated intravascular coagulation (16.3%, 14/86), multiple organ dysfunction syndrome (16.3%, 14/86), hepatic encephalopathy (9.3%, 8/86), and intrauterine fetal death (2.3%, 2/86). ② Treatment and outcome of AFLP pregnant women: the intensive care unit transfer rate of AFLP pregnant women was 66.3% (57/86). 82 cases were improved and discharged after treatment, 2 cases were transferred to other hospitals for follow-up treatment, and 2 cases (2.3%, 2/86) died. ③ Neonatal outcomes: except for 2 cases of intrauterine death, a total of 106 neonates were delivered, including 39 cases (36.8%, 39/106) of neonatal asphyxia, 63 cases (59.4%, 63/106) of neonatal intensive care unit admission, and 3 cases (2.8%, 3/106) of neonatal death. Conclusions: AFLP is a severe obstetric complication, which is harmful to mother and fetus. In the process of clinical diagnosis and treatment, attention should be paid to the clinical manifestations and laboratory tests of pregnant women, early diagnosis and active treatment, so as to improve maternal and fetal outcomes.

OBJECTIVE:
To investigate the correlation between single-nucleotide polymorphism (SNP) of ARID5B gene and resistance to methotrexate (MTX) in children with acute lymphoblastic leukemia (ALL).
METHODS:
A total of 144 children with ALL who were treated in General Hospital of Ningxia Medical University from January 2015 to November 2021 were enrolled and divided into MTX resistant group and non-MTX resistant group, with 72 cases in each group. Matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) technology was used to measure the SNP of ARID5B gene in all children and analyze its correlation with MTX resistant.
RESULTS:
There were no significant differences in the genotype and gene frequency of rs7923074, rs10821936, rs6479778, and rs2893881 between MTX resistant group and non-MTX resistant group (P>0.05). The frequency of C/C genotype in the MTX resistant group was significantly higher than that in the non-MTX resistant group, while the frequency of T/T genotype was opposite (P<0.05). The frequency of C allele in the MTX resistant group was significantly higher than that in the non-MTX resistant group, while the frequency of T allele was opposite (P<0.05). Multivariate logistic regression analysis showed that ARID5B gene rs4948488 TT genotype and T allele frequency were risk factors for MTX resistant in ALL children (P<0.05).
CONCLUSION
The SNP of ARID5B gene is associated with MTX resistant in ALL children.
