Objective: Accurate evaluation of inflammation severity in ulcerative colitis (UC) can guide treatment strategy selection. The potential value of the pericolic fat attenuation index (FAI) on CT as an indicator of disease severity remains unknown.This study aimed to assess the diagnostic accuracy of pericolic FAI in predicting UC severity. Materials and Methods: This retrospective study enrolled 148 patients (mean age 48 years; 87 males). The fat attenuation on CT was measured in four different locations: the mesocolic vascular side (MS) and opposite side of MS (OMS) around the most severe bowel lesion, the retroperitoneal space (RS), and the subcutaneous area. The fat attenuation indices (FAI MS, FAI OMS, and FAI RS) were calculated as the fat attenuation measured in MS, OMS, and RS, respectively, minus that of the subcutaneous area, and were obtained in the non-enhanced, arterial, and delayed phases. Correlations between the FAI and UC Endoscopic Index of Severity (UCEIS) were assessed using Spearman’s correlation. Predictors of severe UC (UCEIS ≥7) were selected by univariable analysis. The performance of FAI in predicting severe UC was evaluated using the area under the receiver operating characteristic curve (AUC). Results: The FAIMS and FAI OMS scores were significantly higher than FAI RS in three phases (all P < 0.001). The FAIMS and FAI OMS scores moderately correlated with the UCEIS score (r = 0.474–0.649 among the three phases). Additionally, FAI MS and FAI OMS identified severe UC, with AUC varying from 0.77 to 0.85. Conclusion Increased CT attenuation of pericolic adipose tissue could serve as a noninvasive marker for evaluating UC severity. FAI MS and FAI OMS of three phases showed similar prediction accuracies for severe UC identification.

Diabetic cognitive dysfunction （DCD） is one of the complications of diabetes， which is characterized by impaired brain structure and progressively decreased learning and memory ability. With the increasing incidence of diabetes worldwide， DCD has become a serious medical and social problem. However， its pathophysiological mechanisms are not well understood. The occurrence and development of DCD involve multiple pathological links and mechanisms， and the prevention and treatment require multi-link and multi-target therapeutic measures. At present， there is no specific drug to prevent or improve DCD. Hypoglycemic drugs such as metformin and vigagliptin or anti-dementia drug including Donepezil are commonly used in clinical treatment to delay the occurrence and progression of cognitive dysfunction， but these drugs have a single target and obvious side effects. Traditional Chinese medicine has a long history in the prevention and treatment of diabetes and central cognitive diseases， and it has many unique advantages such as multiple components， multiple targets， side effects， and low price. A large number of studies have confirmed that traditional Chinese medicine has a significant prevention and treatment effect on DCD， which can improve insulin resistance， synaptic dysfunction， inflammation， oxidative stress， endoplasmic reticulum stress， and neuronal apoptosis by regulating phosphatidylin-ositol 3-kinase （PI3K）/protein kinase B （Akt）， advanced glycation end products （AGEs）/advanced glycation end products receptor （RAGE）/nuclear transcription factor-κB （NF-κB）， NOD-like receptor thermal protein domain associated protein 3 （NLRP3） inflammasome， and endoplasmic reticulum stress and nuclear factor E₂ related factor 2 （Nrf2）/antioxidant response element （ARE） signaling pathways. This article reviewed the effects and related mechanisms of traditional Chinese medicine on DCD in recent years， so as to provide a reference for the prevention and treatment of DCD by traditional Chinese medicine.

OBJECTIVE To monitor plasma concentration of anti-tuberculosis drugs in children, and explore the influencing factors and safety of anti-tuberculosis drugs, and promote the rational use of drugs. METHODS The plasma drug concentration monitoring results of isoniazid, rifampicin, pyrazinamide and ethambutol, the adverse drug reactions and the changes of various parameters before and after treatment in 40 children with tuberculosis were analyzed retrospectively in Zhejiang Hospital of Integrated Tradtional Chinese and Western Medicine. RESULTS The compliance rates of plasma drug concentration of isoniazid, rifampicin, pyrazinamide and ethambutol in chlidren with tuberculosis were 48.15%, 34.88%, 73.81%, 18.52%, respectively. Isoniazid(P=0.0250), rifampicin(P=0.0212) concentrations were positively correlated with daily dose. Age was also one of the factors affecting the concentrations of isoniazid(P=0.0430) and rifampicin(P=0.0057). Serum albumin(P=0.0475) and sex(P=0.0087) were correlated with rifampicin and pyrazinamide, respectively. Abnormal liver function(5/40, 12.50%) and rash(4/40, 10%) were the most common adverse drug reaction. Aspartate aminotransferase(AST), alanine aminotransferase(ALT) and uric acid levels increased after treatment with anti-tuberculosis drugs. CONCLUSION The plasma drug concentrations of isoniazid, rifampicin and ethambutol in children are low. The anti-tuberculosis drugs maybe related to the increase of AST, ALT and uric acid. Therefore, monitoring of serum drug concentration, renal fuction and liver function during anti-tuberculosis treatment is helpful to improve drug safety and implement individualized treatment.

Objective:To summarize the clinical characteristics of patients with epilepsy caused by focal cortical dysplasia (FCD), and identify the influencing factors for postoperative seizure controls.Methods:Fifty-seven patients with epilepsy caused by FCD admitted to Department of Neurosurgery, Third Affiliated Hospital of Zhengzhou University from July 2019 to November 2023 were chosen; standard preoperative evaluation, surgery, postoperative management and follow-up were performed. A retrospective study of clinical data, imaging and video electroencephalogram (VEEG) data, surgical approaches, pathological findings, and follow-up data was performed; influencing factors for postoperative seizure controls were analyzed.Results:In these 57 patients with epilepsy caused by FCD, 29 were males (50.88%) and 28 were females (49.12%). Onset age was 30.00 (8.00, 74.50) months, and surgery age was 95.00 (50.00, 138.50) months. Focal to bilateral tonic-clonic seizures (42/57; 73.68%) and epileptic spasms (13/57; 22.81%) were common seizure types. Cranial MRI was positive in 34 patients (59.65%), mainly manifested as abnormal cortical gyri/sulci morphology (17/57; 29.82%). In 43 patients accepted PET-CT, hypometabolic sites were detected in 40 (93.02%), and complete agreement between PET/MRI fusion results and actual lesion sites was noted in 40 (93.02%). FCD type I was noted in 16 patients (28.07%), type II in 39 (68.42%), and type III in 2 (3.51%). By December 2023, 44 (77.19%) had Engel grading I, 4 (7.02%) had grading II, 4 (7.02%) had grading III, and 5 (8.77%) had grading IV. Children with good prognosis (Engel grading I+II) and those with poor prognosis (Engel grading III+IV) showed significant differences in terms of time from first seizure to surgery, positive/negative MRI, and regularity of postoperative ASMs ( P<0.05). Conclusions:Focal to bilateral tonic-clonic seizure is the most common seizure type in patients with epilepsy caused by FCD, and abnormal cortical gyri/sulci morphology is the most common MRI manifestation; PET/MRI fusion imaging is superior to PET-CT or MRI in identifying epileptogenic foci. Poor seizure control can be noted in patients with long onset time to surgery, with negative cranial MRI results, or with irregular postoperative ASMs.

Objective:To understand the relevant situation of people seeking tattoo removal in laser cosmetic clinics.Methods:A face-to-face questionnaire survey was conducted among respondents seeking tattoo removal who visited the Laser Cosmetic Clinic of the Provincial Hospital Affiliated to Shandong First Medical University from June 2021 to May 2022. The questionnaire survey content included 4 categories and a total of 30 questions: basic information of the tattoo respondents, tattoo-related situations, respondents’ cognition of tattoos, and tattoo removal needs. The questionnaire responses were statistically analyzed, and differences were analyzed according to the gender, age of the tattoo respondents, and educational level at the time of tattooing. Descriptive statistical analysis was conducted on the general information of the questionnaire; Mantel-Haenszel chi-square test or Pearson’s chi-squared test were used for the analysis of the difference in the composition ratio of each data.Results:A total of 150 questionnaires were distributed and 142 valid questionnaires were collected. There were 81 male and 61 female tattoo respondents, with an age of (21.8±4.9) years (13-41 years). The result of the survey showed that 52.8%(75/142) of the respondents were minors (<18 years old) at the time of tattooing, and 97.2%(138/142) were <24 years old at the time of tattooing; 67.6% (96/142) regretted the act of tattooing; 73.2%(104/142) of the respondents themselves asked for the removal of tattoos; who removed their tattoos for personal development (joining the army, working, studying) was 68.3%(97/142); only 23.2%(33/142) of the respondents understood the harms of tattoos; and 21.8%(31/142) of the respondents suffered from adverse reactions after getting tattoos. The percentage of respondents who hid their tattoos from their family members was 82.4%(117/142); the percentage of respondents whose family members approved of the tattoos was only 25.4%(36/142). Analysis of variance showed that there was no correlation between the education level of the respondents and their knowledge of the tattoo risks( P>0.05); the reasons for removing tattoos were correlated with the age and gender of the respondents at the time of consultation ( P<0.01); the size of tattoos was correlated with the gender of the respondents ( P<0.01) and the female respondents were more inclined to choose a small tattoo; the age of tattooing of the respondents was correlated with the level of education of the respondents when they had tattooed themselves ( P<0.01), the proportion of tattoos aged <18 years old was highest among respondents with junior high school education at the time of tattooing [76.2%(32/42)], and this proportion tended to decrease significantly as the education level at the time of tattooing increased. Conclusion:The respondents seeking tattoo removal in the laser cosmetic clinic are mainly teenagers. About half of the respondents were minors at the time of tattooing, and most of them were not aware of the tattoo risks. There is a certain correlation between the age of the respondents and their educational background at the time of tattooing. There are certain differences in the reasons for removing tattoos among respondents depending on gender and age. There is no correlation between the educational background of the respondents and their understanding of the tattoo risks.
