AIM:To evaluate the optimal timing of preoperative intravitreal anti vascular endothelial growth factor(VEGF)therapy in proliferative diabetic retinopathy(PDR)using intraoperative fluorescein angiography(IOFA).METHODS:A retrospective case series study was conducted on patients who underwent vitrectomy for PDR with vitreous hemorrhage(VH)at Sichuan Provincial People's Hospital from January 2023 to February 2025. Patients were divided into three groups according to the interval between intravitreal conbercept injection and surgery: Group A(3 d before surgery), Group B(7 d before surgery), and Group C(14 d before surgery). IOFA was used to assess the number and size of retinal neovascularization(NV). Additional data were collected including preoperative best corrected visual acuity(BCVA), vitreous hemorrhage grading, operative time, frequency of intraoperative endodiathermy, duration of high perfusion pressure, vitreoretinal adhesion grade, postoperative BCVA, and central macular thickness(CMT). Multidimensional analyses were performed.RESULTS:This study enrolled a total of 91 patients(94 eyes)with PDR accompanied by vitreous hemorrhage. Among them, Group A consisted of 31 patients(31 eyes; 18 males, 13 females; mean age 53.26±12.38 y), Group B consisted of 34 patients(37 eyes; 21 males, 13 females; mean age 51.61±14.16 y), and Group C consisted of 26 patients(26 eyes; 18 males, 8 females; mean age 51.00±12.02 y), with baseline characteristics comparable among the three groups(all P>0.05). Comparative analysis of NV visualized via IOFA revealed that both the number and size of NVs were significantly lower in Groups B and C than in Group A(all P<0.0167), while no statistically significant differences were observed between Groups B and C(both P>0.05). No significant differences were found among the three groups regarding other intraoperative parameters, including operation time, frequency of electrocoagulation application, duration of high perfusion pressure, or grading of vitreoretinal adhesion(all P>0.05).CONCLUSION:IOFA confirms that preoperative anti-VEGF therapy administered 7 or 14 d before surgery is more effective than a 3 d interval in suppressing retinal NV activity in PDR patients.

Introduction: Diabetic ketoacidosis (DKA) is a life-threatening complication associated with significant morbidity and healthcare burden. Despite advances in diabetes care, recurrent DKA remains common, often reflecting gaps in treatment adherence and patient education. Identifying predictors of recurrence is crucial for risk stratification and targeted intervention. Methodology: We conducted a retrospective observational study of all adult DKA admissions to a tertiary centre between 2001 and 2025. Electronic medical records were reviewed for demographic data, biochemical parameters, precipitating factors, and clinical outcomes. DKA was defined using standard biochemical criteria. Recurrent DKA was defined as ≥2 admissions during the study period. Factors associated with recurrent DKA admissions were analyzed. Patients under the age of 18 years and those with missing vital information were excluded. Results: A total of 667 DKA admissions, comprising 566 patients, were identified, of which 101 admissions (15.1%) were recurrent, involving 65 patients. Among recurrent DKA episodes, the most common precipitating factors were infection (64.4%) and insulin omission (62.4%). After multivariate analyses, patients with type 1 diabetes mellitus (T1DM) were more likely to develop recurrent DKA compared to those with type 2 diabetes mellitus (aOR 4.16; 95% confidence interval [CI] 2.58–6.70; p <0.001). Insulin omission was strongly associated with recurrent DKA (aOR 2.29; 95% CI 1.46–3.60; p <0.001). In contrast, baseline glycated hemoglobin and chronic kidney disease were not significantly associated with recurrence. Diabetic counseling during the first DKA admission did not reduce recurrent DKA. There were no significant differences in mortality (3.9% vs 6.2%, p = 0.524) or critical care admission rates (40.6% vs 38.7%, p = 0.718) between recurrent and first DKA episodes. Conclusion Recurrent DKA accounts for a substantial proportion of DKA admissions and is strongly associated with insulin omission and T1DM. Our findings suggest that recurrent DKA is driven predominantly by behavioral and adherencerelated factors, indicating the need for multidisciplinary interventions beyond standard inpatient counseling.
Diabetic Ketoacidosis ; Retrospective Studies

Introduction: The rising incidence of diabetic ketoacidosis (DKA) in type 2 diabetes mellitus (T2DM) represents a paradigm shift from its traditional recognition as a hallmark complication of type 1 diabetes mellitus (T1DM). However, contemporary data comparing clinical presentation, precipitating factors, and outcomes between these two populations remain limited. Methodology: In this retrospective observational study, all adult DKA admissions with T1DM or T2DM at a tertiary centre between 2001 and 2025 were studied. DKA was defined according to standard biochemical criteria. Electronic medical records were reviewed to extract demographic data, biochemical parameters, precipitating factors, management details, and clinical outcomes of all adult DKA admission in T1DM and T2DM. Patients aged <18 years or those with incomplete data were excluded. Results: A total of 601 DKA episodes were analyzed, comprising 130 (21.6%) in patients with T1DM and 471 (78.4%) in those with T2DM. Mean age was 26.9 ± 0.71 years for T1DM and 52.1 ± 0.7 years for T2DM. Gender distribution was balanced (male 48.3%, female 51.7%). Mean hemoglobin A1c (HbA1c) was 11.3 ± 0.3% in T1DM and 12.1 ± 0.2% in T2DM. Infection was the most common precipitating factor overall (69.0%), occurring more frequently in T2DM than in T1DM (74.7% vs. 56.2%), followed by medication non-adherence (62.4% vs. 43.8%). Significant differences were observed between groups in admission pH, bicarbonate (both p <0.001), blood ketones (p = 0.028), and HbA1c (p = 0.010), whereas anion gap (p = 0.056) and blood glucose levels (p = 0.755) did not differ significantly. Clinical outcomes were comparable with respect to intensive care unit (ICU) admission rates (40.0% in T1DM vs. 39.0% in T2DM, p = 0.779) and median resolution time (p = 0.462). However, the median length of hospital stay was significantly longer in T2DM (8.2 ± 0.32 vs. 5.4 ± 0.4 days; p <0.001). Overall mortality was 6.0%, with substantially higher mortality in T2DM compared to T1DM (7.4% vs. 0.8%, p = 0.013). Conclusion In this large regional series of adult DKA, most episodes occurred in T2DM. Despite similar ICU admission rates and time to resolution, T2DM was associated with more frequent infection-related precipitants, longer hospital stays, and higher mortality, underscoring the need for targeted preventive strategies in this population.

Introduction: Diabetic ketoacidosis (DKA) in pregnancy is an uncommon yet life-threatening emergency, with disproportionate risks to both mother and fetus. Pregnancy-specific physiological changes predispose patients to rapid metabolic decompensation, often with atypical presentations. Despite this, local data remain limited. We describe the clinical profile, precipitating factors, and outcomes of DKA in pregnancy in a tertiary centre, with emphasis on potentially preventable triggers. Cases: Nine pregnant patients with DKA were identified from a retrospective review of all cases admitted for DKA from 2002 to 2025. Mean age was 31.67 ± 5.20 years; all were Malay. The majority had type 2 diabetes mellitus (55.6%), followed by type 1 diabetes (33.3%) and latent autoimmune diabetes in adults (11.1%). The mean period of amenorrhea was 19.67 ± 12.62 weeks. Infection was the leading precipitant (44.4%), with additional triggers including insulin omission (22.2%), hyperemesis gravidarum, preterm labor, steroid exposure, and perioperative fasting. Most diagnoses were made in the emergency department (55.6%). Biochemical parameters reflected significant severity (mean bicarbonate 7.89 ± 2.98 mmol/L; anion gap 25.00 ± 5.81), with 88.9% classified as severe DKA. Intensive Care Unit (ICU) care was required in 77.8% of cases. The majority (77.8%) were admitted to the ICU unit, with a median time to resolution of 13.00 ± 12.00 hours (interquartile range [IQR]), and the median hospital length of stay was 7.00 ± 5.00 days (IQR). Complications during treatment included hypokalemia (33.3%), acute kidney injury (22.2%), and hypoglycemia (11.1%). Rebound DKA occurred in one-third of patients. All patients were discharged clinically stable. Outcome data demonstrated pregnancy loss in three cases and one preterm birth. Conclusion DKA in pregnancy remains a severe and resource-intensive condition. This series highlights missed opportunities in prevention, with modifiable precipitants such as infection and insulin omission commonly identified. The high severity at presentation suggests delays in recognition. Early detection, optimized metabolic care, and targeted preventive strategies are crucial to improving maternal and fetal outcomes.

OBJECTIVE To explore the mechanism of Jiawei xiaochaihu decoction against hippocampal neuronal apoptosis in acute epileptic model mice. METHODS Thirty-six male KM mice were randomly divided into four groups with 9 mice in each group： normal control group （normal saline）， epilepsy model group （normal saline）， Jiawei xiaochaihu decoction group [7 g/（kg·d）] and carbamazepine group [positive control， 30 mg/（kg·d）]. Except for the normal control group， the acute epilepsy model was established in the other groups. After successful modeling， mice in each group were given corresponding drugs or normal saline by intragastric administration once a day for 2 consecutive weeks. After drug intervention， the ultrastructure and pathological morphology of hippocampal CA1 region were observed. The number of TUNEL-positive cells in hippocampus was detected， and the expression levels of protein kinase B （AKT）， Caspase-3， B-cell lymphoma-extra large （Bcl-xL）， Bcl-2-associated X protein （Bax）， as well as the ratio of phosphorylated AKT（p-AKT） to AKT were determined. RESULTS Compared with the normal control group， severe ultrastructural and pathological damages were observed in the hippocampal CA1 region of epilepsy model group； the number of TUNEL-positive cells was significantly increased （ P ＜0.05）. The expression levels of p-AKT and Bcl-xL were significantly down-regulated （ P ＜0.05）， while the Bax and Caspase-3 were significantly up-regulated （ P ＜0.05），accompanied by a remarkable decrease of p-AKT/AKT ratio （ P ＜0.05）. Compared with the epilepsy model group， hippocampal tissue ultrastructure， pathological damage， and the aforementioned indicators were significantly improved in Jiawei xiaochaihu decoction group （ P ＜0.05）. CONCLUSIONS Jiawei xiaochaihu decoction can inhibit hippocampal neuronal apoptosis in acute epileptic mice， and its mechanism may be related to activating AKT phosphorylation， increasing p-AKT/AKT ratio， up-regulating Bcl-xL expression and down-regulating the expression of Bax and Caspase-3.

Objective: To analyze the status of wasting among primary and secondary school students in Guangxi from 2021 to 2025, to explore the factors associated with wasting, so as to provide scientific evidence for improving student s nutrition. Methods: Based on the National Surveillance and Intervention Program on Common Diseases and Health Risk Factors among Students, a stratified cluster random sampling was adopted from 2021 to 2025 to recruit 71 077, 236 511, 243 466, 249 619 and 246 259 primary and secondary school students in Guangxi for physical examination and questionnaire survey. The χ 2 test was used for intergroup comparisons. Chi-square trend test was used to conduct trend analysis. Multilevel Logistic regression model was employed to identify factors associated with wasting. Results: The overall wasting detection rate was 11.65% during 2021-2025. Over the five year period, the rate exhibited a S shaped fluctuation pattern characterized by "decline-rise-decline" and the difference across years was statistically significant ( χ 2=230.53, P <0.05). Multilevel Logistic regression analysis showed that male students ( OR = 1.63 ), primary school students ( OR =1.53) and junior high school students ( OR =1.12), boarding students ( OR =1.08), and students with adequate sleep duration ( OR =1.12) were positively correlated with the risk of wasting (all P <0.05). Students who consumed sugar sweetened beverages ≥1 time/day ( OR =0.93), ate fresh fruit ≥1 time/day ( OR =0.95), had moderate to vigorous physical activity for more than 60 minutes per day ( OR =0.88), and had moderate to vigorous physical activity for more than 60 minutes per day on more than half of weekend days ( OR =0.88) were negatively correlated with the risk of wasting (all P <0.05). Conclusions Wasting status among primary and secondary school students in Guangxi improved between 2021 and 2025, though fluctuations persisted. Greater attention should be paid to the nutritional status of male students and boarding students. While cultivating balanced dietary habits and appropriate exercise behaviors, the complex relationship between sleep and malnutrition should also be given due consideration.
