Purpose:
This study aimed to evaluate the long-term efficacy of the ligation of the intersphincteric fistula tract (LIFT) procedure in treating high transsphincteric fistulas.
Methods:
We conducted a retrospective study to evaluate the success rate of LIFT treatment in 82 patients with high transsphincteric fistulas involving at least one-third of the external sphincter. This study was carried out across 2 centers from November 2009 to February 2023.
Results:
All patients underwent successful surgery with a median operative time of 48.9 minutes (range, 20–80 minutes), and no intraoperative or postoperative complications were reported. The median follow-up duration was 85.5 months (range, 4–120 months), with 5 patients (6.1%) lost to follow-up. Treatment was successful in 62 patients, whose symptoms disappeared and both the external opening and the intersphincteric incision completely healed, yielding an overall efficiency rate of 80.5%. There were 15 cases (19.5%) of treatment failure, including 6 (7.8%) that converted to intersphincteric anal fistula and 9 (11.7%) that experienced persistent or recurrent fistulas. Only 1 patient reported minor overflow during the postoperative follow-up, but no other patients reported any significant discomfort. There were no statistically significant differences between patients with surgical success and those with treatment failure in terms of fistula length, history of previous abscess or anal fistula surgery, number of external orifices or fistulas, and location of fistulas (all P>0.05).
Conclusion
LIFT is a safe and effective sphincter-preserving procedure that yields satisfactory healing outcomes and has minimal impact on anal function.

Objective To understand the situation of dental cone beam computed tomography (CBCT) quality control testing phantoms in radiation health technical service institutions in Guangdong province, analyze the differences among different phantoms, and provide a reference for dental CBCT quality control testing. Methods The testing phantoms of 49 radiation health technical service institutions were used as the research objects. The designated CBCT equipment was used for scanning and imaging. The Z-score method was used to evaluate the high-contrast resolution, low-contrast resolution, and distance measurement deviation of each phantom. Results The satisfaction rates of various items for the phantoms in 49 institutions ranged from 85.7% to 100%. The distance measurement deviations of four institutions were “suspicious”, and the high-contrast resolution of four institutions and the distance measurement deviation of one institution were “unsatisfactory”. Conclusion The overall performance of dental CBCT quality control testing phantoms in radiological health technical service institutions in Guangdong province is satisfactory. However, there are still some phantoms with poor results in items such as distance measurement deviation and high-contrast resolution. The structural design, material selection, and manufacturing process of the phantom may all affect the results of quality control testing. Therefore, appropriate phantoms, optimized exposure conditions, and suitable reconstruction algorithms should be used in CBCT quality control testing to ensure accurate and reliable measurements.

ObjectiveTo evaluate the clinical efficacy and safety of Huaban Jiedu Formulation (化斑解毒方, HJF) in treating psoriasis vulgaris with blood-heat syndrome. MethodsA randomized, double-blind, placebo-controlled study was conducted with 60 patients diagnosed with psoriasis vulgaris of blood-heat syndrome. Patients were randomly assigned to either a treatment group or a control group, with 30 cases in each. The treatment group received HJF granules orally, one dose a day, combined with topical Qingshi Zhiyang Ointment (青石止痒软膏), while the control group received placebo granules, one dose a day, combined with the same topical ointment. Both groups were topically treated twice daily of 28 days treatment cours. Psoriasis area and severity index (PASI), visual analogue scale for pruritus (VAS), traditional Chinese medicine (TCM) syndrome scores, dermatology life quality index (DLQI), and psoriasis life stress inventory (PLSI) were assessed before treatment and on day 14 and day 28. Response rates for PASI 50 (≥50% reduction) and PASI 75 (≥75% reduction), as well as overall clinical efficacy, were compared between groups. Serum levels of interleukin-6 (IL-6) and interleukin-17 (IL-17) were measured before and after 28 days of treatment. Adverse reactions during treatment were recorded. ResultsAfter 28 days of treatment, both groups showed significant reductions in PASI total score, lesion area score, erythema, scaling, and infiltration scores, pruritus VAS score, TCM syndrome score, DLQI, PLSI, and serum IL-6 and IL-17 levels (P<0.05). Compared to the control group, the treatment group had significantly greater improvements in PASI total score and erythema score, TCM syndrome score, serum IL-6 and IL-17 levels, and PASI 50 response rate after 28 days (P<0.05). Between-group comparisons of score differences before and after 28-day treatment revealed that the treatment group showed significantly better improvements in PASI total, lesion area score, erythema score, TCM syndrome score, DLQI, PLSI, and inflammatory markers (P<0.05 or P<0.01). The total effective rate on day 14 and day 28 was 40.00% (12/30) and 83.33% (25/30) in the treatment group, versus 6.90% (2/29) and 41.38% (12/29) in the control group, respectively. The clinical efficacy in the treatment group was significantly superior to that in the control group (P<0.05). Mild gastric discomfort occurred in 3 patients in the treatment group and 1 in the control group. ConclusionHJF can effectively improve skin lesions and TCM symptoms relieve pruritus, enhance quality of life, and reduce inflammatory markers IL-6 and IL-17, in patients with blood-heat syndrome of psoriasis vulgaris, with a good safety profile.

Yinyang Gongji Pills have the effects of strengthening the body resistance to eliminate pathogenic factors, removing stasis, and reducing swelling, which is a commonly used traditional Chinese medicine(TCM) formula for treating intestinal accumulation. A real-world, registered, and single-arm clinical trial was conducted to observe the clinical efficacy and safety of Yinyang Gongji Pills combined with capecitabine in the treatment of advanced colorectal cancer and analyze the clinical characteristics of the patients. A total of 60 patients with advanced colorectal cancer who refused or could not tolerate standard treatment of western medicine were included in the study. They were treated with Yinyang Gongji Pills combined with capecitabine until disease progression or intolerable adverse events occurred. The main observation indicators were progression-free survival(PFS) and safety. The treatment effects of the patients under different baseline characteristics were analyzed. The clinical trial has found that the median PFS of all enrolled patients was 7.3 months, with 30.1% of patients having a PFS exceeding 12.0 months. Layered analysis showed that the median PFS of patients with the onset site being the colon and rectum were respectively 8.4 and 4.7 months. The median PFS of patients with high, medium, and low tumor burden were respectively 7.0, 4.7, and 10.8 months. The median PFS of patients with wild-type and mutant-type RAS/BRAF were respectively 7.9 and 6.9 months. The median PFS of patients with KPS scores ≥80 and ≤70 were respectively 7.9 and 6.5 months. The median PFS of patients treated with Yinyang Gongji Pills for ≥6, 3-6, and ≤3 months were respectively 8.0, 5.2, and 4.2 months. The median PFS of patients with spleen, kidney, liver, and lung syndrome differentiation in TCM were respectively 8.3, 6.7, 7.3, and 5.6 months. The median PFS of patients with TCM pathological factors including phlegm, dampness, and blood stasis were respectively 7.0, 7.3, and 6.5 months. Common adverse reactions include anemia, decreased white blood cells, decreased appetite, fatigue, and hand foot syndrome, with incidence rates being respectively 44.2%, 34.6%, 42.3%, 32.7%, and 17.3%. The results showed that the combination of Yinyang Gongji Pills and capecitabine demonstrated potential clinical efficacy and good safety in this study. The patients have clinical characteristics such as low tumor burden, onset site at the colon, KPS scores ≥ 80, long duration of oral TCM, and TCM syndrome differentiation including spleen or liver.

Objective To characterize the properties of Hepa1-6-derived microparticles (Hepa1-6-MPs), investigate their stimulatory effects on dendritic cells (DCs) and their cellular uptake pathways, and explore the specific cytotoxic effects of CD8+ T cells induced by Hepa1-6-MP-loaded DCs on hepatoma cell lines, with the aim of developing a novel immunotherapeutic model for hepatocellular carcinoma (HCC). Methods The isolated Hepa1-6-MPs were identified using Western blotting, transmission electron microscopy (TEM) and dynamic light scattering (DLS). Flow cytometry was used to assess the uptake pathways of Hepa1-6-MPs by DCs. Subsequently, enzyme-linked immunosorbent assay (ELISA) was used to measure the effects of Hepa1-6-MP-loaded DCs on the release levels of tumor necrosis factor α(TNF-α) and interferon γ(IFN-γ) into the supernatant of CD8+ T cells. Lactate dehydrogenase (LDH) tests were conducted to evaluate the cytotoxic effects of CD8+ T cells stimulated by Hepa1-6-MP-loaded DCs on hepatoma cells. Results The morphology, size and protein markers of Hepa1-6-MPs met the established criteria. Hepa1-6-MPs enhanced the expression of DC maturation markers CD80 and CD86, and were internalized by DCs via clathrin-mediated endocytosis and phagocytosis pathways. Subsequently, Hepa1-6-MP-loaded DCs stimulated CD8+ T cells to release high levels of TNF-α and IFN-γ, which induced their specific cytotoxicity against HCC cells. Conclusion These findings suggest that Hepa1-6-MP-loaded DCs may be a promising HCC immunotherapeutic tool.

Abuse of amphetamine-based stimulants is a primary public health concern. Recent studies have underscored a troubling escalation in the inappropriate use of prescription amphetamine-based stimulants. However, the neurophysiological mechanisms underlying the impact of acute methamphetamine exposure (AME) on sleep homeostasis remain to be explored. This study employed non-human primates and electroencephalogram (EEG) sleep staging to evaluate the influence of AME on neural oscillations. The primary focus was on alterations in spindles, delta oscillations, and slow oscillations (SOs) and their interactions as conduits through which AME influences sleep stability. AME predominantly diminishes sleep-spindle waves in the non-rapid eye movement 2 (NREM2) stage, and impacts SOs and delta waves differentially. Furthermore, the competitive relationships between SO/delta waves nesting with sleep spindles were selectively strengthened by methamphetamine. Complexity analysis also revealed that the SO-nested spindles had lost their ability to maintain sleep depth and stability. In summary, this finding could be one of the intrinsic electrophysiological mechanisms by which AME disrupted sleep homeostasis.
