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 prepare the β -cyclodextrin （ β -CD） inclusion complex with volatile oil from Qianghuo qushi qingwen granules， and to characterize and quantitatively analyze the inclusion complex. METHODS The comprehensive scores calculated by inclusion rate and inclusion compound yield were used as indicators for screening the inclusion method. The single-factor experiments and Box-Behnken response surface experiments were used to op timize the inclusion conditions， with the above comprehensive score as response value， and taking the ratio of β -CD to volatile oil， inclusion temperature and inclusion time as indexes. The volatile oil inclusion complex of Qianghuo qushi qingwen granules was prepared according to the determined optimal process， followed by validation. Ultraviolet （UV）-visible spectroscopy， thin-layer chromatography （TLC）， and microscopic imaging were also performed. Ultra-high performance liquid chromatography was used to determine the contents of perillaldehyde， pogostone and atractylodin. RESULTS The saturation aqueous solution method was adopted. The optimal inclusion process conditions were as follows： the ratio of β -CD to volatile oil was 7.5∶1， the inclusion temperature was 40 ℃， and the inclusion time was 2.2 h. In three verification experiments， the average inclusion rate was 72.32%， the average yield of inclusion compound was 74.45%， the average comprehensive score was 72.96 points， and the relative error with the predicted value （74.15 points） of the model was 1.61%. UV-visible spectroscopy， TLC and microscopic imaging showed that β -CD and volatile oil successfully formed a new inclusion complex. The average contents of perillaldehyde， pogostone and atractylodin were 4.498 2， 0.814 9， 0.905 7 mg/g， respectively， with RSDs of 0.31%， 0.56% and 0.63% （ n ＝3）. CONCLUSIONS A stable and feasible preparation process of the volatile oil inclusion complex of Qianghuo qushi qingwen granules is successfully established.

Objective: To investigate the association between uric acid level and elevated blood pressure among children and adolescents in Guangzhou, so as to provide a scientific basis for prevention and control of hypertension in the pediatric population. Methods: From March to December 2019, using stratified cluster random sampling, 3 626 children and adolescents aged 6-17 years without elevated blood pressure at baseline were recruited from 6 primary and secondary schools in Guangzhou. Serum uric acid levels were measured at baseline, and divided into four groups ( Q1-Q 4) based on age and sex specific quartiles for analyses. Two waves of follow up were carried out from October 2020 to May 2021 and from October 2021 to May 2022, respectively. Multilevel robust Poisson regression was used to evaluate the association between uric acid level and elevated blood pressure among children and adolescents. The additive interaction between high uric acid level and sugar sweetened beverage (SSB) intake on elevated blood pressure was assessed by stratification analysis and calculation of the relative excess risk due to interaction (RERI). Results: A total of 1 131 new cases of elevated blood pressure were identified during the two follow ups, with an incidence density of 130.5 cases 1 000 person years. Multilevel robust Poisson regression analysis showed that after adjusting for confounders such as gender, age and annual family income, compared with those in the uric acid Q 1 level, the risk of elevated blood pressure in individuals in the Q 4 level increased by 25% ( RR=1.25, 95%CI =1.08-1.44), and the risk of elevated systolic blood pressure increased by 20% ( RR=1.20, 95%CI =1.05-1.36) (both P <0.05); no statistical association was observed between uric acid and elevated diastolic blood pressure (all P >0.05). In the stratified analysis, the statistical associations of uric acid Q 4 level with elevated blood pressure ( RR=1.34, 95%CI =1.13-1.58) and elevated systolic blood pressure ( RR=1.33, 95%CI =1.14-1.55) were only observed in the group with SSB intake ≥ 250 mL/week (both P <0.05). The RERI values for the effect of uric acid Q 4 and Q 3 levels with SSB intake ≥ 250 mL/week on elevated systolic and diastolic blood pressure were 0.29 and 0.44 (both P <0.05). Conclusions High uric acid level is a risk factor for elevated blood pressure among children and adolescents, with a predominant effect on systolic blood pressure. High uric acid level and SSB intake synergistically promote the increase of blood pressure of children and adolescents.

ObjectiveBased on the theory of "gut-prostate" axis， this study explored the effects and mechanisms of Zishen Tongguan formula and Cinnamomi Cortex in the formula in treating rats with chronic non-bacterial prostatitis（CNP） by detecting the levels of inflammatory factors， and the composition and structure of intestinal flora in CNP rats. MethodsEight out of 42 SD rats were randomly selected as the normal group， and the remaining rats were injected with carrageenan to prepare the CNP model. After successful modeling， 32 rats were randomly divided into the model group， Ningmitai capsule group（0.50 g·kg^-1）， Zishen Tongguan formula group（2.00 g·kg^-1）， and the Phellodendri Chinensis Cortex-Anemarrhenae Rhizoma pair group（PCC-AR group， 2.00 g·kg^-1）， with 8 rats in each group. The administered groups were given the corresponding medicinal solution by gavage， and the normal and model groups were intragastrically administered with an equal volume of normal saline， once a day for 14 consecutive days. The prostate tissues of rats were collected and subjected to hematoxylin-eosin（HE） staining and Masson staining to observe the pathological changes of the tissues in each group. Enzyme-linked immunosorbent assay（ELISA） was used to detect the levels of related inflammatory factors in rat serum， and 16S rDNA sequencing was used to analyze the abundance and diversity changes of gut microbiota before and after administration， and species difference analysis was performed. ResultsAll the administered groups could alleviate the inflammatory symptoms of CNP rats， increase the expression levels of anti-inflammatory factors and decrease the expression levels of pro-inflammatory factors， with the most sIgnificant effect observed in the Zishen Tongguan formula group. Compared with the normal group， the expression levels of interleukin（IL）-8， hypersensitive C-reactive protein（hs-CRP）， immunoglobulin（Ig）M， secretory IgA （sIgA）， and inducible nitric oxide synthase（iNOS） were sIgnificantly increased in the model group（P<0.01）. Compared with the model group， the expression levels of the above inflammatory factors in all administered groups were significantly reduced（P<0.01）. When compared with the PCC-AR group， the Zishen Tongguan formula group showed a significant decrease in transforming growth factor（TGF）-β₁ expression level（P<0.05） and a significant increase in IgM expression level（P<0.01）. The results of gut microbiota analysis showed that， compared with the PCC-AR group， at the order level， the Zishen Tongguan formula group significantly reduced the relative abundance of conditional pathogens such as Bacteroidales， Acidaminococcales， Rhodospirillales， Clostridiales， and Elusimicrobiales（P<0.01）. And at the genus level， the Zishen Tongguan formula group significantly decreased the relative abundance of pathogenic microbiota such as Lachnospira and Bacteroides（P<0.01） and significantly increased the relative abundances of beneficial microbiota such as Ruminococcus and Lactobacillus（P<0.01）. ConclusionZishen Tongguan formula can reduce the level of harmful intestinal bacteria， increase the level of beneficial intestinal bacteria， down-regulate the expression of serum inflammatory factors， and the small amount of Cinnamomi Cortex in the formula may play a key role in the treatment of CNP with this formula.

OBJECTIVE To analyze the quantity transfer rule in the processing of Astragalus membranaceus before and after moistening-soaking and steaming-soaking followed by cutting. METHODS Three batches of A. membranaceus decoction pieces processed through moistening-soaking and steaming-soaking followed by cutting were prepared. The HPLC overlapping fingerprints of A. membranaceus and its decoction pieces were established through the Similarity Evaluation System of Chromatographic Fingerprints of TCM （2012 edition）. Combined with the previous qualitative analysis results， the common peaks were identified， the changes of common peak area were analyzed， and the principal component analysis was carried out. The contents of calycosin-7-glucoside， astragaloside Ⅰ and astragaloside Ⅳ in A. membranaceus and its decoction pieces were determined by HPLC， and the content differences of each component in different samples were compared. RESULTS The results of fingerprint analysis showed that 17 common peaks were identified. After steaming-soaking and moistening-soaking of A. membranaceus， the proportion of common peak area in the decoction pieces changed compared with the original medicine （for example， in A. membranaceus steaming-soaking decoction pieces， the proportion of peak area of malonyl calycosin-7-glucoside and malonyl astragaloside Ⅰ decreased， while the proportion of peak area of calycosin-7-glucoside increased）. The results of principal component analysis showed that A. membranaceus， and its decoction pieces after moistening-soaking and steaming-soaking followed by cutting were all clustered into one category respectively. The results of content determination showed that， compared with A. membranaceus， the average content of calycosin-7-glucoside in A. membranaceus moistening-soaking decoction pieces was significantly reduced （P＜0.05）； the average contents of calycosin-7-glucoside and astragaloside Ⅳ in A. membranaceus steaming- soaking decoction pieces were significantly increased （P＜0.05）； there was no significant difference in the average content of astragaloside Ⅳ in A. membranaceus moistening-soaking decoction pieces and astragaloside Ⅰ in the two decoction pieces （P＞ 0.05）. CONCLUSIONS There are differences in the quantity transfer rules of A. membranaceus before and after moistening-soaking and steaming-soaking followed by cutting. Steaming-soaking followed by cutting may make the transformation of unstable components （such as malonyl calycosin-7-glucoside and malonyl astragaloside Ⅰ） more complete.

Objective To compare the efficacy and safety of gemcitabine combined with conventional-dose cisplatin(70 mg/m2,day 2)versus split-dose cisplatin(35 mg/m2,days 1 and 8)in neo-adjuvant therapy for muscle-invasive bladder cancer(MIBC).Methods The clinical data of 33 MIBC patients receiving(gemcitabine+cisplatin,GC)-based neoadjuvant chemotherapy in the Department of Urology of Xinhua Hospital,during Jan.2021 and Aug.2024 were retrospectively analyzed,including 18(54.5％)patients treated with a conventional-dose regimen(GC group),and 15(45.5％)patients treated with a split-dose regimen(GCs group).The efficacy endpoints and incidence/severity of adverse reactions were compared between the two groups.Results Baseline characteristics were well-balanced between the two groups(P＞0.05).No significant differences were observed in the complete response rate(CR:33.3％vs.22.2％),objective response rate(ORR:66.7％vs.61.1％),or disease control rate(DCR:80.0％vs.88.9％)between the GCs and GC groups(P＞0.05).The GCs group exhibited a significantly lower incidence of chemotherapy-related renal injury(6.7％vs.38.9％,P＜0.05),while the occurrence of other adverse events was comparable between the two groups.Notably,the GCs group demonstrated significantly attenuated nephrotoxicity,as evidenced by markedly smaller changes in estimated glomerular filtration rate[eGFR:(4.5±4.7)％vs.(18.0±11.8)％]and serum creatinine[SCr:(5.7±5.6)％vs.(20.2±19.5)％]compared to the GC group(P＜0.05).Conclusion Compared with the conventional-dose regimen,the split-dose regimen maintains equivalent clinical efficacy of GC-based neoadjuvant chemotherapy while significantly reducing chemotherapy-related nephrotoxicity,thereby providing MIBC patients with a safer therapeutic option.

Objective:To develop the Amputation Scale for Severe Open Pelvic Fractures and explore its application value in patients with severe open pelvic fractures.Methods:A total of 27 patients with severe open pelvic fractures who underwent surgical treatment in Shandong Provincial Hospital Affiliated to Shandong First Medical University from January 2010 to January 2023 were retrospectively analyzed. There were 15 males and 12 females, aged 38.6±11.6 years (range, 13-65 years). There were 13 cases of traffic injuries, 10 cases of fall from height injuries, and 4 cases of mechanical crushing injuries; 20 cases were admitted to the hospital in emergency, and 7 cases were transferred from other hospitals. All fracture types were Tile C, including 14 cases of Tile C1, 8 cases of Tile C2, and 5 cases of Tile C3. There were 16 cases of genitourinary system injury, 8 cases of anal or rectal injury, 12 cases of abdominal injury, 9 cases of chest injury, and 6 cases of craniocerebral trauma. The mangled extremity severity score (MESS) and the Amputation Scale for Severe Open Pelvic Fractures were used to evaluate whether amputation was performed. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of the two evaluation methods were calculated.Results:Among the 27 patients, 21 cases were treated with pelvic external fixator to control the volume, 16 cases were treated with gauze packing to stop bleeding, 8 cases were treated with temporary abdominal aorta occlusion, and 12 cases were treated with laparotomy because of abdominal injury. Seven of the 27 patients died, with a mortality rate of 26%. In 12 cases of one-stage amputation, 3 cases died, including 1 case died of multiple organ failure syndrome, 1 case died of gastrointestinal bleeding on the 7th day after amputation, and 1 case died of severe infection on the 4th day after amputation. Among the 15 cases of one-stage limb salvage, 4 cases died, of which 2 cases of second-stage amputation died of infection on the 5th day after one-stage limb salvage, and 1 case of one-stage limb salvage died of limb necrosis on the 3rd day after one-stage limb salvage. Two patients died of multiple organ failure syndrome. The MESS score of 27 patients was 6(6, 8) points (range, 6-13 points), and the Amputation Scale for Severe Open Pelvic Fractures score was 9.6±1.8 points (range, 6-14 points). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of MESS were 66.7%, 50%, 40%, 75% and 56%, respectively, while those of Amputation Scale for Severe Open Pelvic Fractures were 80%, 89%, 73%, 88% and 82%, respectively. The specificity and accuracy of MESS were significantly lower than those of Amputation Scale for Severe Open Pelvic Fractures ( P<0.05). All 20 patients who survived were followed up for 23.6±7.5 months (range, 11-37 months). Five cases had soft tissue infection at the stump of amputation, which were treated with debridement, and 3 cases underwent skin grafting, and the stump healed well at the last follow-up. Conclusion:The Amputation Scale for Severe Open Pelvic Fractures is better than MESS in the assessment of early amputation in patients with severe pelvic fractures.

Thoracic aortic aneurysm(TAA)significantly endangers the lives of individuals with Marfan syndrome(MFS),yet the intricacies of their biomechanical origins remain elusive.Our investigation delves into the pivotal role of hemodynamic disturbance in the pathogenesis of TAA,with a particular emphasis on the mechanistic contributions of the mammalian target of rapamycin(mTOR)signaling cascade.We un-covered that activation of the mTOR complex 1(mTORC1)within smooth muscle cells,instigated by the oscillatory wall shear stress(OSS)that stems from disturbed flow(DF),is a catalyst for TAA progression.This revelation was corroborated through both an MFS mouse model(Fbn1+/C1039G)and clinical MFS specimens.Crucially,our research demonstrates a direct linkage between the activation of the mTORC1 pathway and the intensity in OSS.Therapeutic administration of rapamycin suppresses mTORC1 activity,leading to the attenuation of aberrant SMC behavior,reduced inflammatory infiltration,and restoration of extracellular matrix integrity—collectively decelerating TAA advancement in our mouse model.These insights posit the mTORC1 axis as a strategic target for intervention,offering a novel approach to manage TAAs in MFS and potentially pave insights for current treatment paradigms.
