Both hyperlipidemic acute pancreatitis and fatty liver disease are associated with lipid metabolism disorders and are commonly comorbid with each other in clinical practice. The pathogenesis of such comorbidity involves the interaction between multiple factors such as hypertriglyceridemia， metabolic syndrome， obesity， and insulin resistance， and these factors may form a vicious cycle and jointly promote disease progression. In clinical practice， hyperlipidemic acute pancreatitis is characterized by severe disease conditions， a high incidence rate of complications， a high mortality rate， and a tendency for recurrence， and it can easily lead to multi-organ damage and even multiple organ failure without timely treatment， posing a serious threat to the life of patients. Starting from the various signaling pathways associated with hyperlipidemic acute pancreatitis comorbid with fatty liver disease， this article discusses the potential molecular mechanisms of synergistic pathogenesis between hyperlipidemic acute pancreatitis and fatty liver disease， so as to provide a reference for the early prevention and treatment of such comorbidity.

Objective:To investigate the utilization of inpatient service and influencing factors among pneumoconiosis patients in Chongqing within one year, and to provide a reference basis for the formulation of relevant policies by health management departments.Methods:From October 2020 to October 2023, a multi-stage cluster random sampling method was adopted to select 2002 patients with confirmed pneumoconiosis as the research subjects. A questionnaire survey was conducted on their basic information, inpatient service utilization within one year, treatment for pneumoconiosis-related symptoms, and choice of medical service institutions. Chi-square test and logistic regression were used for statistical analysis.Results:All 2002 pneumoconiosis patients were male, with 40.16% (804/2002) aged 46-55 years old, and 83.32% (1668/2002) currently residing in rural areas. The monthly income of the patients was 833 (167, 2000) yuan, and 22.03% (441/2002) had no income. 30.97% (620/2002) of the patients spent more than 5001 yuan per year on treatment for pneumoconiosis, and 14.64% (293/2002) had debts of more than 5001 yuan. 42.06% (842/2002) had no work-related injury insurance. 21.68% (434/2002) of the patients self-assessed their health status as very poor or poor. The one-year inpatient rate of the patients was 51.25% (1026/2002), and the total inpatient time within one year was 18 (10, 51) days. The inpatient expenses were 6000 (1000, 16625) yuan. Through univariate analysis, the one-year inpatient rates of pneumoconiosis patients were statistically significantly different among different age groups, current employment status, annual household income levels, types of pneumoconiosis, stages of pneumoconiosis, presence or absence of work-related injury insurance, whether receiving minimum living allowances and social assistance related to pneumoconiosis, and different segments of self-assessed health status ( P<0.05). Patients with stage Ⅲ pneumoconiosis, those who received social assistance and minimum living allowances related to pneumoconiosis had higher one-year inpatient rates ( P<0.05), with OR values of 3.893, 1.859, and 2.589, respectively. Conclusion:The utilization of inpatient service by pneumoconiosis patients is influenced by demographic characteristics, social support, and disease factors. It is necessary to enhance the occupational disease diagnosis and treatment capabilities of primary health institutions, build a multi-level social support network, and ensure that patients can conveniently access medical services.

Endometrial injury diseases are an important factors in female infertility, reduced menstruation, and adverse pregnancy outcomes. Clinical characteristics include intrauterine adhesions, a thin endometrium, and reduced endometrial receptivity. Restoring the morphology of the uterine cavity and promoting endometrial reconstruction are the main goals of treatment. At present, hormone medication and surgery are the major Western medicine treatments. Traditional Chinese Medicine has an advantage in treating endometrial injury and preventing postoperative recurrence. Traditional Chinese Medicine diagnosis focuses on "kidney deficiency" as the primary condition,"blood stasis" as the secondary condition, and combined with "liver depression". Therapeutic strategies aim to "replenish kidney""nourish blood""dispel blood stasis", and improve the endometrium. By means of combination of disease and syndrome, classical prescription addition and subtraction, clinical effective experience, combination of acupuncture and medicine and external treatment of Traditional Chinese Medicine can improve the effect and prognosis of patients with endometrial injury diseases. This article reviews the progress of combined Traditional Chinese and Western Medicine treatment of endometrial injury diseases to provide reference for its clinical treatment.

A method for determination and targeted screening of diflorasone components in health products using ultra performance liquid chromatography-quadrupole time of flight mass spectrometry(UPLC-Q-TOF/MS)was established.Four representative diflorasone and esters(diflorasone,diflorasone diacetate,diflorasone-17-propionate,and diflorasone-21-propionate)were selected to optimize the pretreatment conditions,and 10 mL of extraction solvent dosage,15 min of extraction time and 5 g of salting-out agent as the optimal conditions were selected by response surface methodology.The results showed that the four analytes exhibited good linearity within the concentration range of 2.0?100 μg/L with the chromatographic peak area,and the correlation coefficients(R2)were all greater than 0.9990,while the results of recovery and relative standard deviation could satisfy the requirements of determination.The common characteristic ions of diflorasone and esters werem/z121 andm/z335,and their specific structures were obtained by analyzing the cleavage pathway based on the optimized determination conditions.A targeted screening method for other esters of diflorasone based on characteristic ions guidance strategy was established.This method had many advantages such as high efficiency,high sensitivity and good reproducibility,and could be used for targeted screening of diflorasone and esters in health products.The developed characteristic ion guided strategy could be employed to construct mass spectral databases for various glucocorticoids,enabling comprehensive targeted screening across a broad range of compounds.

OBJECTIVES: To assess the regulatory effect of cannabidiol (CBD) on circadian rhythm sleep disorders following general anesthesia and explore its potential mechanism in a rat model of propofol-induced rhythm sleep disorder. METHODS: An electrode was embedded in the skull for cortical EEG recording in 24 male SD rats, which were randomized into control, propofol, CBD treatment, and diazepam treatment groups (n=6). Eight days later, a single dose of propofol (10 mg/kg) was injected via the tail vein with anesthesia maintenance for 3 h in the latter 3 groups, and daily treatment with saline, CBD or diazepam was administered via gavage; the control rats received only saline injection. A wireless system was used for collecting EEG, EMG, and body temperature data within 72 h after propofol injection. After data collection, blood samples and hypothalamic tissue samples were collected for determining serum levels of oxidative stress markers and hypothalamic expressions of the key clock proteins. RESULTS: Compared with the control rats, the rats with CBD treatment showed significantly increased sleep time at night (20:00-6:00), especially during the time period of 4:00-6:00 am. Compared with the rats in propofol group, which had prolonged SWS time and increased sleep episodes during 18:00-24:00 and sleep-wake transitions, the CBD-treated rats exhibited a significant reduction of SWS time and fewer SWS-to-active-awake transitions with increased SWS aspects and sleep-wake transitions at night (24:00-08:00). Diazepam treatment produced similar effect to CBD but with a weaker effect on sleep-wake transitions. Propofol caused significant changes in protein expressions and redox state, which were effectively reversed by CBD treatment. CONCLUSIONS CBD can improve sleep structure and circadian rhythm in rats with propofol-induced sleep disorder possibly by regulating hypothalamic expressions of the key circadian clock proteins, suggesting a new treatment option for perioperative sleep disorders.

Approximately 30%-40% of epilepsy patients do not respond well to adequate anti-seizure medications (ASMs), a condition known as pharmacoresistant epilepsy. The management of pharmacoresistant epilepsy remains an intractable issue in the clinic. Its early prediction is important for prevention and diagnosis. However, it still lacks effective predictors and approaches. Here, a classical model of pharmacoresistant temporal lobe epilepsy (TLE) was established to screen pharmacoresistant and pharmaco-responsive individuals by applying phenytoin to amygdaloid-kindled rats. Ictal electroencephalograms (EEGs) recorded before phenytoin treatment were analyzed. Based on ictal EEGs from pharmacoresistant and pharmaco-responsive rats, a convolutional neural network predictive model was constructed to predict pharmacoresistance, and achieved 78% prediction accuracy. We further found the ictal EEGs from pharmacoresistant rats have a lower gamma-band power, which was verified in seizure EEGs from pharmacoresistant TLE patients. Prospectively, therapies targeting the subiculum in those predicted as "pharmacoresistant" individual rats significantly reduced the subsequent occurrence of pharmacoresistance. These results demonstrate a new methodology to predict whether TLE individuals become resistant to ASMs in a classic pharmacoresistant TLE model. This may be of translational importance for the precise management of pharmacoresistant TLE.
