Objective To explore the differences in the incidence and severity of diarrhea between patients receiving propylene glycol-melphalan (PG-MEL) or propylene glycol-free-melphalan (PGF-MEL) pretreatment during autologous hematopoietic stem cell transplantation (AHSCT). Methods The clinical data of 30 patients who underwent AHSCT with high-dose melphalan (HDM) pretreatment at the Department of Hematology, Zhongshan Hospital (Xiamen), Fudan University, from January 2024 to November 2025 were retrospectively analyzed. Patients were divided into the PG-MEL group (n＝15) and the PGF-MEL group (n＝15) according to the formulation. The incidence, onset time, maximum daily frequency, duration, type, and severity of diarrhea were compared between the two groups. Oral mucositis, vomiting, infection, fever, and other related adverse events, as well as hematopoietic recovery, were also observed. Results The overall incidence of diarrhea was 93.3% in both groups. There was no significant difference in the onset time of diarrhea between the two groups ([4.0±2.0] d vs [3.0±2.0] d). Compared with the PG-MEL group, the PGF-MEL group had a higher maximum daily frequency of diarrhea (8 [6,14] times vs 6 [4,6] times, P＝0.009), a higher proportion of grade 3–4 diarrhea (57.1% vs 14.3%, P＝0.046), and a longer duration of diarrhea ([8.0±4.0] d vs [5.0±2.0] d, P＝0.033). No statistically significant differences were observed between the two groups in the incidence of other adverse events such as oral mucositis, vomiting, infection, fever, or neutrophil and platelet engraftment times. Conclusions PG-MEL and PGF-MEL showed the same overall incidence of diarrhea in AHSCT. However, the PGF-MEL group experienced more severe diarrhea and longer duration. There were no significant differences between the two formulations in other adverse reactions or short-term transplant outcomes.

Objective:To determine the causal relationship between educational attainment and the risk of allergic rhinitis and (or) eczema using Mendelian randomization (MR) analyses.Methods:This study was a secondary data analysis based on the summary data of genome-wide association studies (GWAS), which involved 293 723 participants (educational attainment) from the Social Science Genetics Association Consortium and 462 013 participants [allergic rhinitis and (or) eczema] from the UK Biobank. Genetic variants that were closely related to educational attainment were identified as instrumental variables. Two-sample MR analyses, including inverse-variance weighted (IVW), MR-Egger regression, weighted median method and weighted model-based estimation, were performed to investigate the causal relationship between educational attainment and the risk of allergic rhinitis and (or) eczema, in which the odds ratio ( OR) values were used as indicators. Results:A total of 70 single-nucleotide polymorphisms (SNPs) were chosen as instrumental variables. The MR-Egger regression results suggested that the genetic pleiotropy was unlikely to bias our results ( P=0.107). In the univariable MR analyses, IVW regression showed that the risk of allergic rhinitis and (or) eczema was OR=1.044 (95% CI: 1.020-1.069, P<0.001) and OR=1.170 (95% CI: 1.074-1.256, P<0.001), respectively, for the increase in the duration of education by one year or one standard deviation ( SD) (3.71 years). In the reverse MR analysis, IVW regression showed little evidence that allergic rhinitis and (or) eczema affected educational attainment ( OR=1.020, 95% CI: 0.927-1.023, P=0.683). The results of the weighted median method and weighted mode-based estimation were consistent with the results of IVW. Conclusion:This study suggests that there is a positive causal relationship between educational attainment and the risk of allergic rhinitis and (or) eczema, which means that educational attainment can increase the occurrence of allergic rhinitis and (or) eczema.

Objective:To study the efficacy and drug-related adverse reactions of long-term appli-cation of biological anti-rheumatic drugs (bDMARDs) to patients with ankylosing spondylitis (AS), and provide reference for clinical diagnosis and treatment.Methods:We retrospectively analyzed the clinical data of AS patients who were followed-up for more than 5 years in the Department of Rheumatology and Immunology of Peking University Shenzhen Hospital. The patients treated with bDMARDs alone or combined with traditional antirheumatic drugs were included as the treatment group, while those who did not receive biological or non-biological antirheumatic therapy were included as the control group. The data collected included clinical sym-ptoms, inflammatory biomarkers, imaging results, drug applications and drug-related adverse reactions, etc. The counting data were tested by χ2 test, the measurement data in normal distribution was tested by t test, and the measurement data that not normally distributed was tested by Mann-Whitney U test. Paired test was used for statistical processing before and after treatment. Results:We collected the data of 114 eligible patients, including 64 in the treatment group and 50 in the control group. There were no significant differences in baseline data between the 2 groups, including mean follow-up time, course of disease, age, sex ratio, HLA-B27 positive rate, morning stiffness duration, night pain, peripheral arthritis, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and imaging. After 5 years, patients in the treatment group had shorter morning stiffness [(3±7) min vs (26±37) min, t=4.827, P<0.01], lower nighttime pain rates [(3/64, 4.8%) vs (29/50,58.0%), χ2=38.329, P<0.01], lower ESR level [(14±14) mm/1 h vs (20±18) mm/1 h, t=2.102, P=0.038], lower CRP level [(7±8) mg/L vs (14±19) mg/L, t=2.431, P=0.017], and lower progression rate of sacroiliac arthritis [(18/64, 28.1%) vs (35/50, 70.0%), χ2=19.786, P<0.01], than the control group. The main drug-related adverse reactions in the treatment groupincluded reversible leucopenia, elevated transaminase level, redness and swelling at the injection site. Conclusion:Biologics treatment for more than 3 consecutive years can effectively control the clinical symptoms of most AS patients, reduce inflammatory indicators and delay the imaging progression of the sacroiliac joint. Without treatment, the imaging progress of the sacroiliac joint in AS patients could be 70% after 5 years.

We report a case of chromoblastomycosis caused by , which was successfully treated by long-pulsed 1064 nm Nd: YAG laser combined with terbinafine. A 60-year-old man was admitted for the presence of a 30 mm×40 mm erythematous plaque on the dorsum of his right hand for about 10 months without any subjective symptoms. Both microscopic examination and tissue biopsy of the lesion showed characteristic sclerotic bodies of chromoblastomycosis. Lesion tissue culture on SDA at 26 ℃ for 2 weeks resulted in a black colony, and slide culture identified the isolate as Fonsecaea species. ITS sequence analysis of the isolate showed a 99% homology with strain KX078407. The susceptibility of the isolate to 9 antifungal agents was determined using the microdilution method according to the guidelines of CLSI M38-A2 protocol, and terbinafine showed the lowest MIC (0.125 μg/ml). We subsequently established a Wistar rat model of chromoblastomycosis using the clinical isolate and treated the rats with long-pulsed 1064 nm Nd: YAG laser (pulse width of 3.0 ms, fluence of 24 J/cm, spot size of 3 mm, frequency of 4 Hz, repeated 3 times at an interval of 30 s) twice a week for a total of 8 sessions. Although the laser treatment alone was not able to eliminate the fungi, histopathological examination showed the aggregation of numerous lymphocytes in the local affected tissue, indicating an immune response that consequently facilitate the regression of the lesion. The patient was successfully treated by long-pulsed 1064 nm Nd: YAG laser once a week combined with terbinafine (0.25 /bid) for 8 weeks, and follow-up for 20 months did not reveal any signs of recurrence.

Objective:To compare the efficacy and safety of octreotide and somatostatin in the treatment of liver cirrhosis and up-per digestive tract hemorrhage. Methods:The randomized controlled trails ( RCTs) on the comparison between octreotide and soma-tostatin in the treatment of liver cirrhosis and upper digestive tract hemorrhage were searched from Cochrane Library, PubMed, Med-line, Embase, China National Knowledge Infrastructure(CNKI), VIP China Science and Technology Journal Database and Wanfang database (till February 2017). The randomized controlled trails meeting the inclusion criteria were collected and the quality of included RCTs was assessed according to the Cochrane Collaboration system review, and then Meta -analysis was performed using RevMan 5. 3 software after data extraction and bias risk assessment. Results:A total of 11 RCTs were included. Meta-analysis showed the efficacy of octreotide group was similar to that of somatostatin group (OR=1. 10, 95%CI:0. 79-1. 53, P=0. 56). The levels of blood transfu-sion and hemostasis of octreotide group were higher than those of somatostatin group (MD=0. 68, 95%CI:0. 54-0. 82, P<0. 01 and MD=6. 26, 95%CI:4. 89-7. 63, P<0. 01). The risk of abdominal pain in octreotide group was lower than that in somatostatin group (OR=0. 43, 95%CI:0. 22-0. 86, P=0. 02). The other adverse reactions were similar in both groups. Conclusion:The efficacy of octreotide is similar to that of somatostatin in the treatment of liver cirrhosis and upper digestive tract hemorrhage, and the effect of som-atostatin is quicker than that of octreotide with less blood transfusion. The adverse reactions are similar in both groups, except that oct-reotide has a lower risk of abdominal pain. The long-term safety of octreotide still needs to be confirmed by performing higher quality and large-sample RCTs.
