Objective: To explore the impact of adverse childhood experiences (ACEs) on health risk behaviors (HRBs) among college students and the mediating role of psychological symptoms, so as to provide a basis for developing intervention strategies. Methods: From March to April 2023, a convenience cluster sample of 1 801 students from 12 universities in Nanning, Liuzhou, Guilin, Wuzhou of Guangxi completed an online survey. A self designed questionnaire, Adverse Childhood Experiences-International Questionnaire (ACE-IQ) and Symptom Checklist-90 (SCL-90) were used for evaluation tools. Binary Logistic regression, structural equation modeling (SEM) and Bootstrap methods were used to analyze the associations and mediating effects. Results: Overall, 71.2% of college students experienced at least one type of ACE, with emotional neglect (40.3%) and emotional abuse ( 25.2 %) having the highest detection rates. The top three HRBs were unhealthy diet (77.8%), physical inactivity (54.1%), and smoking/alcohol use (18.5%). Logistic regression showed that poor family functioning, abuse, and extra familial violence were each associated with an increased risk of smoking/alcohol use ( OR =1.14, 1.11, 1.18) and deliberate self harm ( OR =1.26, 1.19,1.30) (all P <0.05). Experience of abuse increased the risk of high risk sexual behavior and family dysfunction increaded the risk of physical inactivity, respectively ( OR = 1.07 , 1.04, both P <0.05). Mediation analysis revealed that anxiety ( β =0.20) and depression ( β = 0.09 ) partially mediated the pathway from poor family functioning to deliberate self harm; paranoia ( β =0.02) partially mediated the pathway from abuse to high risk sexual behavior; and obsessive-compulsive symptoms ( β =0.26) and depression ( β =0.10) partially mediated the pathway from extra familial violence to deliberate self harm (all P <0.05). Conclusion Psychological symptoms play a mediating role in the association between ACEs and HRBs, and mental health interventions may reduce the risk of HRBs among college students.

Objective To investigate the etiology and treatment of dysuria shortly after holmium laser enucleation of the prostate (HoLEP) for benign prostatic hyperplasia (BPH), so as to improve the therapeutic efficacy. Methods A retrospective analysis was conducted on 1361 BPH patients who received HoLEP at our hospital during Mar. 2018 and Mar. 2025. All patients underwent ultrasound, computed tomography (CT), urethral probing or radiography, cystourethroscopy, and urodynamic testing. The causes, treatments and prognosis of dysuria after operation were summarized. Results ninety-eight patients (7.2%) experienced dysuria within 3 months after surgery, and all patients received initial urethral dilation. Among the 62 cases with urethral stricture, 28 were treated with urethral dilation (average of 8 sessions), 16 underwent external urethral incision, 8 underwent anterior urethroplasty, and 10 underwent transurethral plasma incision for urethral stricture. Of the 12 cases with residual prostate tissue, 5 underwent urethral plasma prostatectomy and 7 received medication. All of the 12 cases with bladder neck contracture underwent transurethral plasma incision of the bladder neck and local drug injection. Five cases with intravesical blood clots underwent urethral blood clot irrigation, 2 of which developed active bleeding and then underwent electrocoagulation. Four cases with detrusor dysfunction had catheters re-indwelled for one week followed by medication. Two cases with stone and one case with tissue fragment impacted in the urethra underwent urethral holmium lithotripsy and cystoscopic removal. All patients underwent reoperation successfully and experienced complete resolution or significant improvement of urinary difficulties. Conclusion A certain proportion of patients experience dysuria after HoLEP, with diverse etiologies. The combination of prevention and treatment can reduce the incidence of dysuria.

OBJECTIVE: To propose a machine learning-based method for predicting the trajectories during manual acupuncture manipulation (MAM), aiming to improve the precision and consistency of acupuncture practitioner' operation and provide the real-time suggestions on MAM error correction. METHODS: Computer vision technology was used to analyze the hand micromotion when holding needle during acupuncture, and provide a three-dimensional coordinate description method of the index finger joints of the holding hand. Focusing on the 4 typical motions of MAM, a machine learning-based MAM trajectory predictive model was designed. By integrating the changes of phalangeal joint angle and hand skeletal information of acupuncture practitioner, the motion trajectory of the index finger joint was predicted accurately. Besides, the roles of machine learning-based MAM trajectory predictive model in the skill transmission of acupuncture manipulation were verified by stratified randomized controlled trial. RESULTS: The performance of MAM trajectory predictive model, based on the long short-term memory network (LSTM), obtained the highest stability and precision, up to 98%. The learning effect was improved when the model applied to the skill transmission of acupuncture manipulation. CONCLUSION The machine learning-based MAM predictive model provides acupuncture practitioner with precise action prediction and feedback. It is valuable and significant for the inheritance and error correction of manual operation of acupuncture.

This study investigated the effects of Rehmanniae Radix Praeparata on striatal neuronal apoptosis in rats with attention deficit hyperactivity disorder(ADHD) based on the B-cell lymphoma-2(Bcl-2)/Bcl-2-associated X protein(Bax)/caspase-3 signaling pathway. Twenty-four 3-week-old male spontaneously hypertensive rats(SHR) were randomly divided into a model group, a methylphenidate group(2 mg·kg~(-1)·d~(-1)), and a Rehmanniae Radix Praeparata group(2.4 mg·kg~(-1)·d~(-1)). Age-matched male Wistar Kyoto(WKY) rats were used as the normal control group, with 8 rats in each group. The rats were administered by gavage for 28 days. Body weight and food intake were recorded for each group. The open field test and elevated plus maze test were used to assess hyperactivity and impulsive behaviors. Nissl staining was used to detect changes in striatal neurons and Nissl bodies. Terminal deoxynucleotidyl transferase dUTP nick end labeling(TUNEL) fluorescence staining was used to detect striatal cell apoptosis. Western blot was employed to detect the expression levels of Bcl-2, Bax, and caspase-3 proteins in the striatum. The results showed that compared with the model group, Rehmanniae Radix Praeparata significantly reduced the total movement distance, average movement speed, and central area residence time in the open field test, and significantly reduced the ratio of open arm entries, open arm stay time, and head dipping in the elevated plus maze test. Furthermore, it increased the number of Nissl bodies in striatal neurons, significantly downregulated the apoptosis index, significantly increased Bcl-2 protein expression and the Bcl-2/Bax ratio, and reduced Bax and caspase-3 protein expression. In conclusion, Rehmanniae Radix Praeparata can reduce hyperactivity and impulsive behaviors in ADHD rats. Its mechanism may be related to the regulation of the Bcl-2/Bax/caspase-3 signaling pathway in the striatum, enhancing the anti-apoptotic capacity of striatal neurons.

The phase changes and quantity-quality transfer of 17 batches of Ostreae Concha(Ostrea rivularis) during the raw material-calcined decoction pieces-standard decoction process were analyzed. The content of calcium carbonate(CaCO_3), the main component, was determined by chemical titration, and the extract yield and transfer rate were calculated. The CaCO_3 content in the raw material, calcined decoction pieces, and standard decoction was 94.39%-98.80%, 95.03%-99.22%, and 84.58%-90.47%, respectively. The process of raw material to calcined decoction pieces showed the yield range of 96.85% to 98.55% and the CaCO_3 transfer rate range of 96.92% to 99.27%. The process of calcined decoction pieces to standard decoction showed the extract yield range of 2.86% to 5.48% and the CaCO_3 transfer rate range of 2.59% to 5.13%. The results of X-ray fluorescence(XRF) assay showed that the raw material, calcined decoction pieces, and standard decoction mainly contained Ca, Na, Mg, Si, Br, Cl, Al, Fe, Cr, Mn, and K. The chemometric results showed an increase in the relative content of Cr, Fe, and Si from raw material to calcined decoction pieces and an increase in the relative content of Mg, Al, Br, K, Cl, and Na from calcined decoction pieces to standard decoction. X-ray diffraction(XRD) was employed to establish XRD characteristic patterns of the raw material, calcined decoction pieces, and standard decoction. The XRD results showed that the main phase of all three was calcite, and no transformation of crystalline form or generation of new phase was observed. Fourier transform infrared spectroscopy(FTIR) was employed to establish the FTIR characteristic spectra of the raw material, calcined decoction pieces, and standard decoction. The FTIR results showed that the raw material had internal vibrations of O-H, C-H, C=O, C-O, and CO■ groups. Due to the loss of organic matter components after calcination, no information about the vibrations of C-H, C=O, and C-O groups was observed in the spectra of calcined decoction pieces and standard decoction. In summary, this study elucidated the quantity-quality transfer and phase changes in the raw material-calcined decoction pieces-standard decoction process by determining the CaCO_3 content, calculating the extract yield and transfer rate, and comparing the element changes, FTIR characteristic spectra, and XRD characteristic pattern. The results were reasonable and reliable, laying a foundation for the subsequent process research and quality control of the formula granules of calcined Ostreae Concha(O. rivularis Gould), and providing ideas and methods for the quality control of the whole process of raw material-decoction pieces-standard decoction-formula granules of Ostreae Concha and other testacean traditional Chinese medicine.

OBJECTIVE: This study aimed to reexplore minimum iodine excretion and to build a dietary iodine recommendation for Chinese adults using the obligatory iodine loss hypothesis. METHODS: Data from 171 Chinese adults (19-21 years old) were collected and analyzed based on three balance studies in Shenzhen, Yinchuan, and Changzhi. The single exponential equation was accordingly used to simulate the trajectory of 24 h urinary iodine excretion as the low iodine experimental diets offered (iodine intake: 11-26 μg/day) and to further deduce the dietary reference intakes (DRIs) for iodine, including estimated average requirement (EAR) and recommended nutrient intake (RNI). RESULTS: The minimum iodine excretion was estimated as 57, 58, and 51 μg/day in three balance studies, respectively. Moreover, it was further suggested as 57, 58, and 51 μg/day for iodine EAR, and 80, 81, and 71 μg/day for iodine RNI or expressed as 1.42, 1.41, and 1.20 μg/(day·kg) of body weight. CONCLUSION The iodine DRIs for Chinese adults were established based on the obligatory iodine loss hypothesis, which provides scientific support for the amendment of nutrient requirements.

Objective To analyze the evaluation value of regulatory T cells(Treg),helper T cells(Th17)and Treg/Th17 changes on the morbidity and severity of viral myocarditis(VMC)patients,and further analyze the influencing factors of morbidity and severity of VMC patients.Methods Press 1∶1 The research objects were screened according to the matching principle.140 VMC patients admitted to Dingzhou People's Hospital from Janu-ary 2022 to January 2024 were selected as the observation group,and the severity of the disease was determined according to the left ventricular ejection fraction(LVEF)and serum troponin(cTnI)levels.According to the severity of the disease,the observation group was divided into a mild group(n=79)and a moderately severe group(n=61).In addition,140 healthy people in the same period were selected as the control group.All patients were followed up for one year.According to the Treg/Th17 cutoff value in the receiver operating characteristic(ROC)curve,the patients were grouped based on the expression levels of the indicators into the Treg/Th17 high-expression group(107 patients)and the Treg/Th17 low-expression group(30 patients).The levels of Treg,Th17,Treg/Th17 and baseline data were compared between the control group and the observation group.The levels of Treg,Th17,Treg/Th17 and baseline data were compared between the mild group and the moderate-severe group.The diagnostic value of the combined detection of Treg,Th17,Treg/Th17 alone and in a parallel mode for the onset and severity of the disease in patients with VMC was analyzed using the ROC curve.Multivariate Logistic regression was used to analyze the influencing factors of the onset and severity of VMC.Results During the study period,4 cases were shed in the observation group,including the study period,4 cases dropped out and 136 cases were included in the observation group,and 3 cases dropped out and 137 cases were included in the control group.Compared with the control group,Treg and Treg/Th17 in the observation group were significantly lower,and Th17 was significantly higher(P<0.05).Th17 was the risk factor affecting the incidence of VMC patients(OR=2.547,2.698),Treg and Treg/Th17 were the protective factors affecting the incidence of VMC patients(OR=0.507,0.519).The area under the curve(AUC),sensitivity and specificity of Treg,Th17 and Treg/Th17 combination in the diagnosis of VMC were higher than those of single detection.Delong's test confirmed that the AUC of the combined detection(0.893)was significantly greater than that of the individual detections of Treg(0.664,Z=7.042),Th17(0.696,Z=6.033),and Treg/Th17(0.721,Z=5.691)(P<0.05).Compared with the mild group,Treg and Treg/Th17 in the moderate and severe group were significantly lower,and Th17 was significantly higher(P<0.05).Treg and Treg/Th17 were the independent protective factors affecting the severity of VMC patients(OR=0.547,0.419),and Th17 was the independent risk factor affecting the severity of VMC patients(OR=2.554)(P<0.05).The AUC,sensitivity and specificity of Treg,Th17 and Treg/Th17 combination in detecting the severity of VMC patients were higher than those of single detection(P<0.05).During the 1-year follow-up,a total of 36 patients with VMC died.The 1-year survival rate and OS of patients with high expression of Treg/Th17 were higher than those of patients with low expression of Treg/Th17(P<0.05).Conclusion During the onset and progression of VMC,there is an imbalance in Treg/Th17 cytokines.Treg/Th17 can serve as an important indicator for detecting the deterioration of the condition in VMC patients at an early stage.Clinically,the combined detection scheme of Treg,Th17,and Treg/Th17 can be used as a reference for clinical assessment of the onset diagnosis and disease progression of VMC patients.

Objective:To investigate the feasibility and safety of endoscopic surgery in the treatment of fibro-adipose vascular anomaly (FAVA).Methods:Clinical data of FAVA patients who underwent endoscopic treatment admitted to Xi’an International Medical Center Hospital from October 1, 2019 to April 1, 2024 were retrospectively analyzed, including gender, age of onset, age of diagnosis, lesion location, operation time, intraoperative blood loss, hospital stays, incision complications, etc. Before endoscopy, magnetic resonance imaging and ultrasound were routinely used to locate the lesion range, and the surgical position and Trocar location were selected according to different lesion sites.Descriptive statistical analysis was conducted using SPSS version 26.0.Results:40 cases of FAVA patients were admitted during the period, all of whom underwent endoscopic radical resection, including 15 males and 25 females. The age of onset was 8 (6, 12.5) years. The age of diagnosis was 11 (8, 22.5) years. There were 31 patients with stage Ⅰ and 9 patients with stage Ⅱ. 31 cases involved the calf, of which 21 involved the calf triceps (gastrocnemius, soleus) and 9 involved the thigh, of which 1 patient had lesions originating from the fascia around the sciatic neurovascular bundle. 11 cases (27.5%) were converted to open surgery. The operative time was 192.5 (107, 292.5) min. The intraoperative blood loss was 35 (10, 87.5) ml. The length of hospital stay for endoscopic surgery was 9 (7, 11) d. The postoperative follow-up time was 11.5 (3.5, 13.5) months. Of the 40 patients, 39 were cured completely without residual pain or joint movement disorder after operation. Postoperative dorsiflexion function of the ankle joint was mildly limited in one patient classified as stage Ⅱ. There was no incision complication and recurrence.Conclusion:For patients with stage Ⅰ and Ⅱ FAVA, endoscopic surgery has concealed incisions, indistinct scars, definite therapeutic effects and high safety.
