PURPOSE: The rate of complications among patients undergoing surgery has increased due to infection with SARS-CoV-2 and other variants of concern. However, Omicron has shown decreased pathogenicity, raising questions about the risk of postoperative complications among patients who are infected with this variant. This study aimed to investigate complications and related factors among patients with recent Omicron infection prior to undergoing orthopedic surgery. METHODS: A historical control study was conducted. Data were collected from all patients who underwent surgery during 2 distinct periods: (1) between Dec 12, 2022 and Jan 31, 2023 (COVID-19 positive group), (2) between Dec 12, 2021 and Jan 31, 2022 (COVID-19 negative control group). The patients were at least 18 years old. Patients who received conservative treatment after admission or had high-risk diseases or special circumstances (use of anticoagulants before surgery) were excluded from the study. The study outcomes were the total complication rate and related factors. Binary logistic regression analysis was used to identify related factors, and odds ratio (OR) and 95% confidence interval (CI) were calculated to assess the impact of COVID-19 infection on complications. RESULTS: In the analysis, a total of 847 patients who underwent surgery were included, with 275 of these patients testing positive for COVID-19 and 572 testing negative. The COVID-19-positive group had a significantly higher rate of total complications (11.27%) than the control group (4.90%, p < 0.001). After adjusting for relevant factors, the OR was 3.08 (95% CI: 1.45-6.53). Patients who were diagnosed with COVID-19 at 3-4 weeks (OR = 0.20 (95% CI: 0.06-0.59), p = 0.005), 5-6 weeks (OR = 0.16 (95% CI: 0.04-0.59), p = 0.010), or ≥7 weeks (OR = 0.26 (95% CI: 0.06-1.02), p = 0.069) prior to surgery had a lower risk of complications than those who were diagnosed at 0-2 weeks prior to surgery. Seven factors (age, indications for surgery, time of operation, time of COVID-19 diagnosis prior to surgery, C-reactive protein levels, alanine transaminase levels, and aspartate aminotransferase levels) were found to be associated with complications; thus, these factors were used to create a nomogram. CONCLUSION Omicron continues to be a significant factor in the incidence of postoperative complications among patients undergoing orthopedic surgery. By identifying the factors associated with these complications, we can determine the optimal surgical timing, provide more accurate prognostic information, and offer appropriate consultation for orthopedic surgery patients who have been infected with Omicron.

OBJECTIVE: To investigate the clinical characteristics and prognostic of venetoclax (VEN) combined targeted therapy in acute leukemia (AL) patients with PICALM∷MLLT10 fusion gene positivity. METHODS: A retrospective analysis was conducted on 16 PICALM∷MLLT10-positive AL patients treated at the First Affiliated Hospital of Soochow University from January 2021 to August 2024. These patients were diagnosed by targeted RNA sequencing (RNA-seq) or reverse transcription multiplex PCR, including newly diagnosed and relapsed/refractory (R/R) cases. The immunophenotypes, genetic features, gene mutations, and the efficacy of VEN combination targeted therapy of patients were evaluated. RESULTS: Among the 16 cases, 3 were confirmed by reverse transcription multiplex PCR, and 13 were detected through targeted RNA-seq among 528 AL patients, with a detection rate of 2.46%. The averge age of patients was (28.0±8.58) years. Patients exhibited diverse immunophenotypes, including 7 cases of acute myeloid leukemia, 5 of acute T-lymphoblastic leukemia, 1 of acute B-lymphoblastic leukemia, 1 of acute undifferentiated leukemia, and 2 of mixed-phenotype acute leukemia. Among them, 11 had extramedullary disease (EMD), 14 expressed CD7, and 12 expressed CD33. Major co-occurring mutations included PHF6 (6 cases), NOTCH1 (5 cases), and 7 cases with complex karyotypes. Of the 12 patients who received standard induction therapy, 7 did not achieve remission (PR+NR). All 4 patients treated with VEN combination therapy achieved complete remission (CR). Among the 7 induction failure cases, 4 achieved CR upon re-induction with VEN, while the remaining 3 re-induced with standard therapy, did not achieve CR. Thirteen patients received allogeneic hematopoietic stem cell transplantation, including 6 who received maintenance therapy with hypomethylating agents (HMA) alone or in combination with VEN, and seven were followed up. Survival analysis showed that the overall survival was better in the maintenance therapy group (P =0.044). CONCLUSION PICALM∷MLLT10-positive AL involves multiple lineages and demonstrates poor response to conventional chemotherapy. VEN combination therapy shows promising efficacy in both newly diagnosed and R/R patients. Post-transplant maintenance therapy with HMA alone or combined with VEN may extend survival; however, further clinical validation is required.

OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

This comprehensive review synthesizes the latest advancements in understanding inflammatory disorders affecting cerebral small vessels, a distinct yet understudied category within cerebral small vessel diseases (SVD). Unlike classical SVD, these inflammatory conditions exhibit unique clinical presentations, imaging patterns, and pathophysiological mechanisms, posing significant diagnostic and therapeutic challenges. Highlighting their heterogeneity, this review spans primary angiitis of the central nervous system, cerebral amyloid angiopathy-related inflammation, systemic vasculitis, secondary vasculitis, and vasculitis in autoinflammatory diseases. Key discussions focus on emerging insights into immune-mediated processes, neuroimaging characteristics, and histopathological distinctions. Furthermore, this review underscores the importance of standardized diagnostic frameworks, individualized immunomodulation approaches, and novel targeted therapies to address unmet clinical demands.

OBJECTIVE: The analgesic effect of acupuncture has been widely accepted. Nevertheless, the mechanism behind its analgesic effect remains elusive, thus impeding the progress of research geared toward enhancing the analgesic effect of acupuncture. This paper investigated the role of acupuncture needle surface textures on acupuncture's analgesic effect by creating four experimental acupuncture needles with different patterns of surface augmentation. METHODS: Four types of acupuncture needles with different surface textures (the lined needle, circle needle, sandpaper needle, and threaded needle) were designed. Additionally, the force/torque measurement system used a robot arm and mechanical sensor to measure the force on the needle during insertion and manipulation. To perform acupuncture analgesia experiments, four experimental acupuncture needles and a normal needle were inserted into the Zusanli (ST36) acupoint of rats with inflammatory pain. By comparing the force and torque and the analgesic efficacy of the different acupuncture needles, these experiments tested the role of acupuncture needle body texture on acupuncture analgesia. RESULTS: The analgesic effects of different acupuncture needle body textures varied. Specifically, the force required to penetrate the skin with the lined needle was not greater than that for the normal needle; however, the needle with inscribed circles and the sandpaper-roughened needle both required greater force for insertion. Additionally, the torque of the lined needle reached 2 × 10^-4 N·m under twisting manipulation, which was four times greater the torque of a normal needle (5 × 10^-5 N·m). Furthermore, the lined needle improved pain threshold and mast cell degranulation rate compared to the normal needle. CONCLUSION Optimizing the texture of acupuncture needles can enhance acupuncture analgesia. The texture of our experimental acupuncture needles had a significant impact on the force needed to penetrate the skin and the torque needed to manipulate the needle; it was also linked to variable analgesic effects. This study provides a theoretical basis for enhancing the analgesic efficacy of acupuncture through the modification of needles and promoting the development of acupuncture therapy.

OBJECTIVE: Recombination events are common and serve as the primary driving force of diverse human adenovirus (HAdV), particularly in children with acute respiratory tract infections (ARIs). Therefore, continual monitoring of these events is essential for effective viral surveillance and control. METHODS: Respiratory specimens were collected from children with ARIs between January 2022 and December 2023. The penton base, hexon, and fiber genes were amplified from HAdV-positive specimens and sequenced to determine the virus type. In cases with inconsistent typing results, genes were cloned into the pGEM-T vector to detect recombination events. Metagenomic next-generation sequencing (mNGS) was performed to characterize the recombinant HAdV genomes. RESULTS: Among 6,771 specimens, 277 (4.09%, 277/6,771) were positvie for HAdV, of which 157 (56.68%, 157/277) were successfully typed, with HAdV-B3 being the dominant type (91.08%, 143/157), and 14 (5.05%, 14/277) exhibited inconsistent typing results, six of which belonged to species B. The penton base genes of these six specimens were classified as HAdV-B7, whereas their hexon and fiber genes were classified as HAdV-B3, resulting in a recombinant genotype designated P7H3F3, which closely resembled HAdV-B114. Additionally, a partial gene encoding L1 52/55 kD was identified, which originated from HAdV-B16. CONCLUSION A novel recombinant, P7H3F3, was identified, containing sequences derived from HAdV-B3 and HAdV-B7, which is similar to HAdV-B114, along with additional sequences from HAdV-B16.

AIM To investigate the effects of different compatibility ratios and processing method on the content of rutin,isoquercetin,ferulic acid,quercetin,isotoosendanin,kaempferol,toosendanin,α-pinene,trans-anethole in the combination use of Toosendan Fructus and Foeniculi Fructus,and to explore the optimal compatibility ratio for its use.METHODS The analysis of HPLC-DAD was performed on a 30℃thermostatic ZORBAX SB C18 column(4.6 mm×250 mm,5 μm),with the mobile phase comprising of acetonitrile-0.1%phosphoric acid flowing at 1.0 mL/min in a gradient elution manner,and the use of DAD detector.SPSS 24.0 software was used to analyze the data differences.RESULTS Nine constituents showed good linear relationships within their own ranges(r≥0.999 1),whose average recoveries were 96.19%-103.13%with the RSDs of 1.86%-2.67%.Generally higher total content of nine constituents were detected in the combination use groups when Toosendan Fructus-Foeniculi Fructus were at ratios of 1 ∶ 1,1 ∶ 2,and 2 ∶ 1 than those single uses(P<0.05),and among which the 1 ∶ 1 ratio contributed the highest total content.After salt processing,decreased content of toosendanin and isotoosendanin,α-pinene and trans-anethole(P<0.05,P<0.01)),increased isoquercetin content(P<0.01),and no significant content changes of other ingredients were detected.CONCLUSION Through this method of high accuracy and good reproducibility,we learn that the combination use of Toosendan Fructus and Foeniculi Fructus promotes the dissolution of the nine constituents,and the maximum content is achieved at ratio of 1 ∶ 1.

Objective:To investigate the level of serum lipoprotein a [Lp (a)] in patients with diffuse large B-cell lymphoma (DLBCL) and its clinical significance.Methods:A retrospective cohort study was performed. The clinical data of 87 patients with DLBCL who were treated at Changshu No.2 People's Hospital from January 2017 to June 2022 (the newly treated DLBCL group) were retrospectively analyzed, and 78 healthy physical examination subjects were selected as the control group. The level of Lp(a) in the two groups and the level of Lp(a) in DLBCL patients achieving different therapeutic effects after treatment were compared. The receiver operating characteristic (ROC) curve was used to analyze the efficacy of serum Lp(a) in predicting the therapeutic effect of DLBCL patients, and the area under the curve (AUC) was calculated to determine the optimal critical value. Based on the optimal critical value, patients with DLBCL were divided into low Lp(a) group and high Lp(a) group, and the clinicopathological characteristics of DLBCL patients with different Lp(a) levels were compared. Cox proportional hazards model was used to analyze the factors affecting the prognosis of DLBCL patients. Kaplan-Meier method was used to compare the relapse-free survival (RFS) and overall survival (OS) of DLBCL patients with different Lp(a) levels.Results:The level of Lp (a) in the newly treated DLBCL group was higher than that in the control group[ (0.24±0.09) g/L vs. (0.09±0.06) g/L], and the difference was statistically significant ( t = 3.61, P = 0.019). Among 87 patients, 54 achieved complete remission (CR), 23 achieved partial remission (PR), and 10 achieved progression of the disease (PD). The Lp (a) levels of patients achieving CR, PR, and PD were (0.09±0.09) g/L, (0.12±0.08) g/L, and (0.25±0.15) g/L, respectively. The Lp (a) levels in patients achieving CR and PR were lower than those in the newly treated DLBCL patients [(0.24±0.09) g/L], and the differences were statistically significant (all P < 0.05). There was no statistically significant difference in the Lp (a) levels between patients achieving PD and the newly treated DLBCL patients ( P > 0.05). The ROC curve results showed that the optimal critical value of serum Lp (a) in predicting the efficacy of DLBCL patients was 0.25 g/L, AUC was 0.776 (95% CI: 0.676-0.876, P < 0.05), and its sensitivity and specificity was 66.67%, 82.76%, respectively. According to the optimal critical value of Lp (a) (0.25 g/L), patients were divided into the low Lp (a) group (≤ 0.25 g/L) (57 cases) and the high Lp (a) group (>0.25 g/L) (30 cases). The proportion of patients with lactate dehydrogenase level >227 U/L, Ann Arbor stage Ⅲ-Ⅳ, and extranodal organ involvement >1 in the high Lp (a) group was higher than that in the low Lp (a) group, and the differences were statistically significant (all P < 0.05). Cox multivariate analysis results showed that Ann Arbor stage Ⅲ-Ⅳ, international prognostic index (IPI) score 3-5, and Lp (a)>0.25 g/L were independent risk factors for OS in DLBCL patients (all P < 0.05); Ann Arbor stage Ⅲ-Ⅳ and IPI score 3-5 were independent risk factors for RFS in DLBCL patients (all P < 0.05). The median OS in the low Lp (a) group was not reached; the median OS of the high Lp (a) group was 21 months, and there was a statistically significant difference in OS between the two groups ( P = 0.001). The median RFS time was not reached in the low Lp (a) group and the high Lp (a) group; and there was no statistically significant difference in RFS between the two groups ( P = 0.102) . Conclusions:Lp(a) level of DLBCL patients is increased, and Lp(a) could be a factor influencing the prognosis of DLBCL.
