Objective:To explore the clinical predicting value of serum intestinal fatty acid-binding protein (I-FABP) in the development of esophageal varices (EV) in patients with chronic hepatitis B cirrhosis.Method:We used case-control study. A retrospective analysis was performed on the clinical data of 169 patients with hepatitis B cirrhosis who were admitted to the Affiliated Hospital of Yanbian University from September 2020 to October 2023. EV diagnosis and grades were based on gastroscopy. Enzyme-linked immunosorbent assay was used to measure the serum level of I-FABP on admission. Spearman correlation analysis was used to investigate the correlation among variables. Contributing factors of EV were evaluated using univariate and multivariate logistic regression analysis. Receiver operating characteristic (ROC) curves were used to evaluate the predictive performance of I-FABP for EV presence.Results:The gastroscopy showed 59 patients without EV. The median of I-FABP in the EV Group was significantly higher than that in the no-EV Group [2.01 (1.39, 2.89) μg/L vs 0.96 (0.77, 1.91) μg/L], and the difference was statistically significant ( Z=5.585, P<0.001). I-FABP showed significant positive correlations between model for end-stage liver disease sore and Von Willebrand Factor Antigen/thrombocyte Ratio ( r=0.523, 0.328, both P<0.001). Multiple logistic regression analysis identified I-FABP as the independent factor contributing to the presence of EV ( OR=1.73, P=0.045). The area under the curve of I-FABP predicting EV was 0.76. The cut-off was 1.46 μg/L. Conclusion:I-FABP is a potential marker for the formation of EV in patients with hepatitis B cirrhosis, and its increased concentration is related to reduced hepatic reserve and portal hypertension.

Objective: To analyze the trends in new diagnosis rates of HIV/AIDS cases in Huzhou City, Zhejiang Province from 2009 to 2023, so as to provide the basis for improving HIV/AIDS prevention and control strategies. Methods: Data of newly reported HIV/AIDS cases in Huzhou City from 2009 to 2023 were collected through the Chinese Disease Prevention and Control Information System. The new diagnosis rate was calculated as the ratio of newly reported HIV/AIDS cases within one year to the permanent resident population during the same period. The gender, age, and regional distribution characteristics of new diagnosis rates of HIV/AIDS cases were described. The trends were analyzed using average annual percent change (AAPC) and annual percent change (APC). Results: A total of 2 088 new HIV/AIDS cases were reported in Huzhou City from 2009 to 2023, with an average annual new diagnosis rate of 4.53/105. The new diagnosis rates showed an overall increasing trend from 2009 to 2023 (AAPC=12.745%, P<0.05), with rapid growth during 2009 to 2015 (APC=32.734%, P<0.05) but no significant trend during 2015 to 2023 (P>0.05). The average annual new diagnosis rate was significantly higher in males than in females (7.54/100 000 vs. 1.40/100 000, P<0.05). Male new diagnosis rate trend closely mirrored the overall population pattern, while females showed a continuous upward trend without clear inflection point (AAPC=12.575%, P<0.05). Age-specific analysis revealed average annual new diagnosis rates of 2.75/100 000, 6.16/100 000 and 3.83/100 000 for AIDS/HIV cases aged <25, 25-<50 and ≥50 years, respectively. The cases aged <25 years showed no significant trend (P>0.05), while the cases aged 25-<50 and ≥50 years followed patterns similar to the overall population. The average annual new diagnosis rates of HIV/AIDS cases in Wuxing District, Nanxun District, Deqing County, Changxing County and Anji County were 6.54/100 000, 3.43/100 000, 3.45/100 000, 3.56/100 000 and 4.94/100 000, respectively, showing overall upward trends (AAPC=9.672%, 27.599%, 11.800%, 18.896% and 10.254%, all P<0.05). Conclusions The new diagnosis rate of HIV/AIDS cases showed an overall upward trend in Huzhou City from 2009 to 2023. Cases are mainly concentrated among males, people aged 25-<50 years and Wuxing District, making them key targets for HIV/AIDS prevention and control.

Objective To investigate the value of intestinal fatty acid binding protein(I-FABP)in predicting the development and progression of acute-on-chronic liver failure(ACLF).Methods A retrospective analysis was performed for the clinical data of 168 patients with decompensated liver cirrhosis who were admitted to The Affiliated Hospital of Yanbian University from September 2020 to March 2023.The conditions of the patients with ACLF on admission were observed,and the patients were followed up for 6 months to identify new-onset ACLF cases.ELISA was used to measure the serum level of I-FABP on admission.The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups,and the Kruskal-Wallis H rank sum test was used for comparison between multiple groups;the chi-square test was used for comparison of categorical data between groups;the Jonckheere-Terpstra test was used for trend analysis.The Spearman correlation analysis was used to investigate the correlation between two variables,and the multivariate Cox regression analysis was used to investigate the influencing factors for new-onset ACLF during follow-up.The Kaplan-Meier curve was used to analyze the onset of ACLF in different groups,and the log-rank test was used for the analysis of such differences.The receiver operating characteristic(ROC)curve and the area under the ROC curve(AUC)were used to investigate the performance of I-FABP in predicting the development and progression of ACLF.Results Among the 168 patients enrolled in this study,there were 43 patients with ACLF and 125 patients without ACLF,among whom 19 developed ACLF during follow-up.The patients with ACLF on admission had a significantly higher level of I-FABP than those without ACLF(Z=4.359,P<0.001).The patients with new-onset ACLF had a significantly higher level of I-FABP than those without new-onset ACLF(Z=3.414,P<0.001).The level of I-FABP increased with the increase in ACLF severity grade(H=17.385,P<0.001,Ptrend<0.001).The multivariate Cox regression analysis showed that I-FABP was independently associated with new-onset ACLF during follow-up(hazard ratio=2.138,95%confidence interval[CI]:1.297-3.525,P=0.003),and the tertile of I-FABP showed a good discriminatory ability(χ2=12.16,P<0.001).The ROC curve showed that I-FABP had a good performance in predicting the development and progression of ACLF,with an area under the ROC curve of 0.854(95%CI:0.791-0.903)and 0.747(95%CI:0.661-0.820),respectively,and an optimal cut-off value of 2.07 μg/L and 1.86 μg/L,respectively.Conclusion I-FABP can be used as a biomarker to predict the development and progression of ACLF,and it may help to identify high-risk patients and improve clinical management.

ObjectiveTo analyze the characteristics of HIV-1 molecular network and pretreatment drug resistance genes in the middle-aged and elderly people aged ≥50 years in Huzhou City, Zhejiang Province, and to provide an evidence for the prevention and control of AIDS epidemic. MethodsA total of 332 samples from the newly reported and untreated AIDS patients aged ≥50 years in Huzhou City from January 2020 to December 2023 were collected, pol genes were amplified by reverse transcription polymerase chain reaction (RT-PCR) and nested polymerase chain reaction (nest⁃PCR). Phylogenetic trees analyzing the subtypes were constructed, and a molecular network with a gene distance threshold of 1.0% were constructed at the same time. Mutation sites of drug resistance-related genes were identified through the Data Analysis and Detection System of HIV-1 Resistance Gene Detection of Stanford University, USA. ResultsSequence samples of 308 patients were obtained, and9 genotypes were identified, including CRF07_BC in 172 cases (55.8%), CRF01_AE in 61 cases (19.8%), CRF08_BC in 43 cases (14.0%), CRF85_BC in 9 cases (2.9%), and CRF55_01B in 8 cases (2.6%), subtype B in 5 cases (1.6%), subtype C in 4 cases (1.3%), CRF67_01B in3 cases (1.0%), and unique recombination URF01_AE/07_BC in 3 cases (1.0%). When the gene distance threshold was 1.0%, 28 molecular clusters were formed, and 139 cases were connected to the network, with an access rate of 45.0%. The largest transmission cluster C1 contained 44 cases infected with CRF07_BC subtype, all of whom were heterosexually transmitted, and predominantly by males. A total of 30 patients were found to have low-grade or higher drug resistance mutations, and the pretreatment drug resistance rate was 9.7% (30/308). Among them, there were 5 cases (16.7%) of protease inhibitor (PI) related drug resistance mutations, and 26 cases (86.7%) of non-nucleoside reverse transcriptase inhibitors (NNRTI) related drug resistance mutations. ConclusionCRF07_BC is the subtype with the most clusters among the middle-aged and elderly infected patients aged ≥50 years in Huzhou City. Middle-aged and elderly transmission clusters are formed within the three counties of WX, NX and CX through related activities. Molecular network monitoring on newly reported cases aged ≥50 years in Huzhou City should be strengthened so that the new characteristics of epidemic changes can be detected in time, providing a scientific basis for adjusting AIDS prevention and control measures for the elderly.

We present a rare case of acute thyrotoxicosis in a man with horse-induced neck trauma. A 60-year-old man presented to our emergency department with a head and neck injury caused by a horse kick. Computed tomography revealed a hematoma in the right thyroid gland. Ultrasonography of the neck revealed a 1.4 cm sized heterogenous hypoechoic lesion with an irregular margin in the right lower pole, suggestive of a thyroid hematoma. A thyroid function test revealed elevated free thyroxine and free triiodothyronine levels and suppressed thyrotropin levels. A Tc-99m thyroid scan showed a mild diffuse decreased uptake in the thyroid gland, especially in the right lower pole. We monitored the thyroid function test results, which took 2 months to recover to the normal range. This case indicates that awareness of thyroid dysfunction and monitoring of thyroid function are vital in patients with neck trauma.
