Objective To investigate the perioperative safety of patients with myasthenia gravis who take high doses of oral glucocorticoids. Methods A retrospective analysis was conducted on the clinical data of patients with myasthenia gravis who received oral glucocorticoids and underwent thoracoscopic thymectomy at the Department of Thoracic Surgery, the University of Hong Kong-Shenzhen Hospital from April 2013 to October 2019. Patients were divided into a high-dose steroid group and a medium-to-low dose steroid group based on the dosage of oral steroids, and the clinical data of the two groups were compared. Results A total of 102 patients were included, including 19 (18.62%) males and 83 (81.37%) females, with an average age of (32.25±9.83) years. There were 75 patients in the medium-to-low dose steroid group and 27 patients in the high-dose steroid group. All patients in both groups successfully completed the surgery without major intraoperative bleeding, conversion to open chest surgery, delayed extubation, severe infection, or perioperative death. The daily oral steroid dose for the high-dose steroid group was (35.81±4.29) mg, and for the medium-to-low dose steroid group it was (15.29±2.17) mg. There was no statistical difference in the operation time [(124.69±23.51) min vs. (117.89±21.46) min, P=0.172] and intraoperative blood loss [(21.19±3.48) mL vs. (20.56±3.41) mL, P=0.419] between the two groups. Postoperatively, 12 (11.76%) patients developed complications: one patient of myasthenic crisis (the medium-to-low dose steroid group), which was improved after short-term respiratory support and intravenous immunoglobulin treatment; 11 patients of respiratory/swallowing difficulties (9 in the medium-to-low dose steroid group and 2 in the high-dose steroid group), which were improved after anticholinergic treatment to reduce oral secretions and sputum suction, and the patients were discharged smoothly. There was no statistical difference in the incidence of postoperative complications between the two groups (P=0.637). Conclusion On the basis of good perioperative management, it is safe and feasible for patients with myasthenia gravis who take high dose of oral steroids to undergo thymectomy, and they have the same perioperative safety as patients with medium-to-low dose steroids.

This paper discussed the differentiation and treatment of chemotherapy-induced nausea and vomiting (CINV) in traditional Chinese medicine, based on the theory of "yin qi descends, while all yang qi ascends” from Inner Canon of Yellow Emperor (《黄帝内经》). The core pathogenesis of CINV is attributed to chemotherapy-induced injury to the middle jiao (焦), resulting in the separation of yin and yang and loss of their mutual communication. Acute and explosive CINV is often characterized by "all yang qi ascends", with stomach yang constraint transforming into fire, and qi counterflow leading to vomiting, which can be treated by unblocking stomach yang, draining fire and scattering the counterflow, with Huoxiang Zhengqi Powder (藿香正气散) and medicinals of clearing function. For delayed cases, which are often due to "yin qi descends", and the accumulation of turbid yin obstructs and constrains the deficient yang, the treatment should focus on promoting qi flow to eliminate turbidity, unblocking and boosting yang qi, and Chengqi-series Formulas (承气类方) or Xiao Banxia Decoction (小半夏汤) can be considered. Refractory and anticipated cases usually involve stomach-kidney deficiency and zang-fu (脏腑) organs disharmony, making yin and yang difficult to restore balance, for which the treatment should focus on nourishing both the stomach and kidneys and harmonize the zang-fu organs, with formulas such as Fuzi Lizhong Decoction (附子理中汤) or Xiaoyao Powder (逍遥散) modified as appropriate.

Introduction:
Improving glycemic control while minimizing unnecessary
insulin exposure is an important goal in diabetes
management. The Rapid Optimization Clinic (ROC) was
established as a structured multidisciplinary service to
support therapy individualization, close follow-up, and
timely insulin deintensification. This audit evaluated early
changes in glycated hemoglobin A1c (HbA1c) and insulin
treatment burden following ROC care over 3 months.
Methodology:
We conducted a retrospective audit of routine clinical
data from patients with diabetes managed in the ROC at a
district hospital. Baseline and 3-month HbA1c and insulin
data were extracted from non-electronic clinic records.
Insulin dose was standardized as total daily dose (TDD)
in units/kg/day. Insulin deintensification was evaluated
primarily by change in TDD from baseline to 3 months and
by the proportion of patients who discontinued insulin
during follow-up. Paired analyses were performed for patients with complete baseline and follow-up data for
each outcome. Continuous variables are presented as mean
± standard deviation or median with interquartile range,
as appropriate. Exploratory analyses were undertaken to
assess whether available patient factors were associated
with HbA1c improvement.
Results:
Twenty-three patients were included. Paired HbA1c data
were available for 12 patients, whereas paired TDD data
were available for 21 patients. Mean HbA1c decreased
from 10.78 ± 2.59% at baseline to 8.42 ± 2.29% at 3 months,
representing a mean reduction of 2.36 percentage points
(95% confidence interval [CI] 0.09–4.62; p = 0.043). Mean TDD
decreased from 0.434 ± 0.248 to 0.286 ± 0.313 units/kg/day,
corresponding to a mean reduction of 0.148 units/kg/day
(95% CI 0.077–0.219; p <0.001). Insulin was discontinued in
9 of 21 patients (42.9%). No clear association was observed
between HbA1c improvement and age, sex, or number of
visits. Interpretation is limited by the small sample size,
reflecting the early phase of a newly established clinic.
Conclusion
In this early audit, ROC care was associated with clinically
meaningful improvement in glycemic control and
significant insulin deintensification over 3 months. These
findings support the potential role of a structured multidisciplinary optimization clinic in delivering individualized
diabetes care and facilitating safe reduction of insulin
burden.

4.Three-channel Recognition Model Based on Visible Light Images for Crop Disease Incubation Stage
Progress in Biochemistry and Biophysics 2025;52(10):2650-2662
ObjectiveEarly detection of crop diseases is crucial for effective agricultural management and yield protection. While visible light imaging has been widely applied for disease detection due to its accessibility and non-destructive nature, most existing methods primarily focus on identifying diseases during the symptomatic phase, when visual symptoms are already prominent. However, detecting plant diseases during the incubation period—when symptoms are still subtle or invisible—remains a major challenge due to the lack of distinctive visual cues and limited research methodologies. This study aims to address this gap by proposing a novel three-channel recognition model to accurately identify early blight symptoms during the incubation stage in Solanaceae crops, particularly in chili and tomato, using only visible light images. MethodsWe established a controlled experimental setup in which healthy leaves and leaves inoculated with early blight pathogens were photographed continuously over time. A total of 1 258 visible light images were collected, capturing various stages of disease progression. From these images, lesion regions were manually annotated. To quantitatively characterize early and subtle color changes within the lesion areas, we extracted color moments—first-order (mean), second-order (standard deviation), and third-order (skewness)—from multiple color spaces, including Lab and HSV. By analyzing the temporal variation of these color moments across disease progression stages, we identified the first-order moment of the saturation (S) channel in the HSV color space as the most sensitive indicator of lesion development on inoculated leaves. Using this insight, we defined four disease categories: healthy, incubation stage, early stage, and late stage. Subsequently, a three-channel classification model was constructed by integrating features from three color channels that provided complementary information. Three-channel models were constructed based on R-G-B, L-a-b, and H-S-V color spaces, respectively, to evaluate performance across different crops and to determine which color representation provides the most discriminative power for identifying disease symptoms during the incubation period. ResultsThe proposed models demonstrated strong classification performance. The three-channel model built using the Lab color space achieved a 94.44% accuracy in recognizing the incubation stage of early blight in pepper, effectively distinguishing subtle pre-symptomatic features from healthy tissue. The model based on the HSV color space achieved 100% accuracy in detecting incubation-stage symptoms in tomato, underscoring the discriminative power of S-channel variations in this context. These results confirm the model’s capability to identify early blight before visible lesions become pronounced, which is essential for timely disease intervention. ConclusionThis study presents a new technical pathway for early-stage disease detection using visible light images by focusing on subtle color feature changes during the incubation period. The proposed three-channel recognition model effectively identifies early blight in both chili and tomato, offering a non-destructive, low-cost, and easily deployable solution for early warning and precision agriculture. Furthermore, this framework can be generalized to other crops and diseases where early detection plays a critical role in minimizing yield losses and ensuring sustainable production. The method lays a solid foundation for future research in pre-symptomatic plant disease recognition and provides valuable tools for intelligent crop monitoring and precision management systems.

AIM: To investigate the predictive value of serum histone deacetylase 1(HDAC1)and endothelial nitric oxide synthase(eNOS)for infectious endophthalmitis after cataract surgery.METHODS: A total of 362 cataract patients(362 eyes)admitted to our hospital from January 2020 to January 2023 were selected as the research objects. According to the occurrence of postoperative infectious endophthalmitis, they were divided into infection group(15 cases, 15 eyes)and non-infection group(347 cases, 347 eyes). Enzyme linked immunosorbent assay(ELISA)was applied to detect the levels of serum HDAC1 and eNOS in all subjects, and the levels of serum HDAC1 and eNOS in both groups were compared; the influencing factors of infectious endophthalmitis were analyzed by multivariate Logistic regression; the receiver operative curve(ROC)was applied to analyze the predictive value of serum HDAC1 and eNOS levels for postoperative infectious endophthalmitis in cataract patients.RESULTS: The levels of serum HDAC1 and eNOS in the infected group were obviously higher than those in the uninfected group(all P<0.01). Surgical time, vitreous overflow, HDAC1, and eNOS were all risk factors for postoperative infectious endophthalmitis(all P<0.05). ROC results showed that the AUC of HDAC1 and eNOS in predicting postoperative infectious endophthalmitis in cataract patients was 0.878 and 0.877, respectively, with sensitivity of 88.7% and 87.7%, specificity of 70.4% and 7.8%, respectively, while the AUC of the two combination in predicting postoperative infectious endophthalmitis in cataract patients was 0.978, with a sensitivity of 86.7% and a specificity of 85.3%.CONCLUSION:The serum levels of HDAC1 and eNOS in patients with infectious endophthalmitis after cataract surgery are obviously increased, and the combined detection of serum HDAC1 and eNOS can improve the predictive efficacy of infectious endophthalmitis in cataract patients after surgery. Both can provide reference for clinical diagnosis and treatment.
