Objective: To explore the association between mental health status and adverse childhood experiences (ACEs) among sexual minority college students, so as to provide a scientific basis for mental health education and health promotion in universities. Methods: From January to February 2024, convenience and cluster sampling methods were used to select 1 792 college students from 11 colleges in Guangxi. A self reporting method was applied to identify 476 sexual minority individuals. The Symptom Check-List 90 (SCL-90) and the Simplified Chinese Adverse Childhood Experiences International Questionnaire (SC-ACE-IQ) were employed to assess mental health and ACEs. Multivariate Logistic regression analysis was conducted to examine the associations. Results: The detection rates of all psychological issues among sexual minority college students in Guangxi were significantly higher than those of non sexual minority college students ( χ 2=56.01-91.39, all P <0.01). Except for physical neglect, bullying, and community violence, sexual minority students exhibited higher reporting rates of other ACEs types compared to nonsexual minority students ( χ 2= 4.52-13.34, all P <0.05). The total ACEs score for college students was 1.00 (1.00, 2.00), while the SCL-90 total score was 96.00 (113.00, 160.00). Spearman correlation analysis revealed a positive correlation between ACEs total scores and SCL-90 total scores ( r=0.29, P <0.05). Additionally, all ACEs subscales, including emotional neglect, physical neglect, emotional abuse, sexual abuse, parental loss, domestic violence, and community violence were positively correlated with corresponding SCL-90 subscale scores ( r =0.05-0.22, all P <0.05). Multivariate Logistic regression analysis showed that family violence increased the risk of mental health issues for sexual minority students ( OR=1.61, 95%CI =1.26-2.09); emotional neglect ( OR= 1.05 , 95%CI =1.00-1.10), physical neglect ( OR=1.20, 95%CI =1.06-1.35), sexual abuse ( OR=1.49, 95%CI =1.15-1.93) increased mental health risks for non sexual minority students (all P <0.05). The cumulative effects of ACEs were all statistically significant in the total sample and both subgroups (all P <0.05). Conclusion Mental health status among sexual minority college students in Guangxi is associated with ACEs, and their well being requires active attention

Numerous c-mesenchymal-epithelial transition (c-MET) inhibitors have been reported as potential anticancer agents. However, most fail to enter clinical trials owing to poor efficacy or drug resistance. To date, the scaffold-based chemical space of small-molecule c-MET inhibitors has not been analyzed. In this study, we constructed the largest c-MET dataset, which included 2,278 molecules with different structures, by inhibiting the half maximal inhibitory concentration (IC₅₀) of kinase activity. No significant differences in drug-like properties were observed between active molecules (1,228) and inactive molecules (1,050), including chemical space coverage, physicochemical properties, and absorption, distribution, metabolism, excretion, and toxicity (ADMET) profiles. The higher chemical diversity of the active molecules was downscaled using t-distributed stochastic neighbor embedding (t-SNE) high-dimensional data. Further clustering and chemical space networks (CSNs) analyses revealed commonly used scaffolds for c-MET inhibitors, such as M5, M7, and M8. Activity cliffs and structural alerts were used to reveal "dead ends" and "safe bets" for c-MET, as well as dominant structural fragments consisting of pyridazinones, triazoles, and pyrazines. Finally, the decision tree model precisely indicated the key structural features required to constitute active c-MET inhibitor molecules, including at least three aromatic heterocycles, five aromatic nitrogen atoms, and eight nitrogen-oxygen atoms. Overall, our analyses revealed potential structure-activity relationship (SAR) patterns for c-MET inhibitors, which can inform the screening of new compounds and guide future optimization efforts.

Objective To investigate the difference of surgical effect of exclusion,simple continuous suture and circular suture suspension in TAPP for the treatment of false hernia sac in patients with direct inguinal hernia.Method From May 2020 to May 2022,120 patients diagnosed with direct inguinal hernia and treated with TAPP in our hospital were retrospectively.The false hernia sacs were divided into three groups according to different methods of treatment patients treated with false hernia sac exclusion were included in group A,those treated with simple continuous suture were included in group B,and those treated with circular suture suspension were included in group C.There were 40 patients in each group.The perioperative indicators(operation time,intraoperative blood loss,postoperative hospital stay,hospitalization cost)and postoperative effects(chronic pain,seroma,incision or mesh infection,foreign body traction feeling)were compared among the three groups.Results All 120 patients successfully completed TAPP surgery.There was no significant difference in general condition,intraoperative blood loss,postoperative hospital stay,wound or mesh infection and chronic pain among the three groups(P＞0.05).The operation time of group B and C was longer than that of group A,and the incidence of seroma was significantly lower than that of group A,the difference was statistically significant(P＜0.05).The incidence of foreign body traction in group A and group C was lower than that in group B,and the difference was statistically significant(P＜0.05).The hospitalization cost of group B and group C was lower than that of group A,with statistically significant difference(P＜0.05).Conclusion In clinical practice,direct hernia and false hernia sac often need to be treated.In direct hernia TAPP operation,simple continuous suture method and circular suture suspension method have the effect of improving the condition of the false hernia sac,but in terms of economy and postoperative effect,the circular suture suspension method can benefit patients more.

BACKGROUND:Disseminated intravascular coagulation(DIC)is associated with increased mortality in sepsis patients.In this study,we aimed to assess the clinical ability of sepsis-induced coagulopathy(SIC)and sepsis-associated coagulopathy(SAC)criteria in identifying overt-DIC and pre-DIC status in sepsis patients. METHODS:Data from 419 sepsis patients were retrospectively collected from July 2018 to December 2022.The performances of the SIC and SAC were assessed to identify overt-DIC on days 1,3,7,or 14.The SIC status or SIC score on day 1,the SAC status or SAC score on day 1,and the sum of the SIC or SAC scores on days 1 and 3 were compared in terms of their ability to identify pre-DIC.The SIC or SAC status on day 1 was evaluated as a pre-DIC indicator for anticoagulant initiation. RESULTS:On day 1,the incidences of coagulopathy according to overt-DIC,SIC and SAC criteria were 11.7％,22.0％and 31.5％,respectively.The specificity of SIC for identifying overt-DIC was significantly higher than that of the SAC criteria from day 1 to day 14(P＜0.05).On day 1,the SIC score with a cut-off value＞3 had a significantly higher sensitivity(72.00％)and area under the curve(AUC)(0.69)in identifying pre-DIC than did the SIC or SAC status(sensitivity:SIC status 44.00％,SAC status 52.00％;AUC:SIC status 0.62,SAC status 0.61).The sum of the SIC scores on days 1 and 3 had a higher AUC value for identifying the pre-DIC state than that of SAC(0.79 vs.0.69,P＜0.001).Favorable effects of anticoagulant therapy were observed in SIC(adjusted hazard ratio[HR]=0.216,95％confidence interval[95％CI]:0.060-0.783,P=0.018)and SAC(adjusted HR=0.146,95％CI:0.041-0.513,P=0.003). CONCLUSION:The SIC and SAC seem to be valuable for predicting overt-DIC.The sum of SIC scores on days 1 and 3 has the potential to help identify pre-DIC.

Objective To evaluate the short-term efficacy and safety of percutaneous liver puncture for local management of portal vein thrombosis(PVT).Methods Variations in thrombus,blood flow,and laboratory examination results were observed before and after percutaneous liver puncture in 197 patients with PVT,and the occurrence of comorbidities was recorded and followed up for one year after treatment.Results After treatment,the thrombus in the main portal vein vessels almostly disappeared in 119 patients(60.41％)with PVT,the thrombus had a significant reduction in 57 patients(28.93％),and the thrombus had a smaller change or an increase in 21 patients(10.66％);146 patients(74.11％)had smooth blood flow in the main portal vein vessels,29 patients(14.72％)showed significant improvement in blood flow,and 22 patients(11.17％)showed no significant improvement or worsening of blockage.The mean portal venous pressure was significantly lower than that before treatment(P＜0.001);thrombin time,activated partial thromboplastin time,and prothrombin time were prolonged compared to those before thrombolysis(P＜0.001),and fibrinogen were reduced compared to those before thrombolysis(P＜0.001).A total of 35 patients(17.77％)occured comorbidities during treatment.One year after treatment,196 patients(99.49％)with PVT survived,of which thrombus essentially disappeared in 141(71.94％),thrombus stabilized(or decreased)in 42(21.43％),and thrombus increased in 13(6.63％).Conclusion percutaneous liver puncture for local management of PVT is effective and reliable in the short-term and requires standardized management of the entire process.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective To investigate the impact and related mechanisms of L-carnitine on lipid metabolism,microinflammation,and oxidative stress status in hemodialysis patients with chronic kidney disease,and explore the potential mechanisms.Methods The data of patients with chronic kidney disease receiving dialysis admitted to Xingtai People's Hospital from January 2022 to January 2023 were collected,and they were divided into levocanidin group(levocanidin+conventional treatment)and conventional treatment group.The two groups were compared in terms of treatment safety and renal function indexes[blood creatinine(Scr)and urea nitrogen(BUN)],lipid metabolism status[total cholesterol(TC),triglycerides(TG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),apolipoprotein A1(ApoA1),apolipoprotein B(ApoB),and serum free carnitine(FC)],microinflammatory markers[interleukin-6(IL-6),interleukin-8(IL-8),tumor necrosis factor alpha(TNF-α),and C-reactive protein(CRP)]and oxidative stress markers[malondialdehyde(MDA),superoxide dismutase(SOD),and glutathione peroxidase(GSH-Px)].Results A total of 120 patients were included in the study,with 60 in each group.After 6 months of treatment,there was no statistically significant difference in the incidence of adverse reactions between the two groups(P＞0.05),but the Scr and BUN of the patients in the levocanidin group were lower than those in the conventional treatment group(P＜0.05),and the therapeutic efficacy rate was higher than that in the conventional treatment group(P＜0.05).Regarding lipid metabolic status,serum TC,TG,LDL-C and ApoB levels of patients in the levocanitine group decreased compared with those before treatment(P＜0.05),while serum ApoA1 and FC were elevated(P＜0.05);and serum ApoB levels of patients in the conventional treatment group decreased compared with those before treatment(P＜0.05).The levels of TC,TG,LDL-C and ApoB were significantly lower and the levels of ApoA1 and FC were significantly higher in the leucovorin group than in the conventional treatment group(P＜0.05),whereas there was no significant difference in the levels of serum HDL-C(P＞0.05).In terms of microinflammatory status,IL-6,IL-8,TNF-α,and CRP levels decreased in both groups compared with those before treatment(P＜0.05),but IL-6,IL-8,TNF-α,and CRP levels of patients in the leucovorin group were significantly lower than those in the conventional treatment group(P＜0.05).As for the oxidative stress indexes,the SOD and MDA levels of patients in both groups decreased(P＜0.05),while the GSH-Px levels increased(P＜0.05)compared with the pretreatment;and compared with the conventional treatment group,patients in the levocanitine group had higher levels of GSH-Px,and lower levels of SOD and MDA(P＜0.05).Conclusion The use of L-carnitine may further ameliorate microinflammation and oxidative stress by improving lipid metabolism in dialysis patients with chronic kidney disease.

Objective:To explore the clinical effect of cosmetic reconstruction for partial defect of distal segment of digits.Methods:Form January 2018 to January 2021, the Department of Hand Surgery of Institute for Hygiene of Ordnance Industry(The 521 Hospital of Weapon Industry) admitted 129 patients with partial defect of distal segment of thumb or fingers with phalange or tendon exposure. The patients were 111 males and 18 females with an average age of 34(17-59) years old. The sizes of nailbed defect were 0.4 cm×1.1 cm-1.8 cm×2.0 cm, the length of phalange defect was 0.4-1.8 cm, and the sizes of the soft tissue defect were 1.6 cm×1.8 cm-3.2 cm×4.8 cm. Great toe tissue flaps were used to reconstruct the partial defect of distal segment of thumb or fingers after debridement. Wounds of fibular flap of great toe in 77 cases were directly sutured in 17 patients. The donor sites in rest 60 great toes were narrowed first and then repaired with skin grafts in 10 cases, with artificial dermis in 28 cases and with transverse V-Y advancement flaps of ipsilateral great toes for 22 cases. Forty-nine of 52 donor site wounds for hallux toenail flap were repaired with artificial dermis and 3 with free peroneal artery perforator flaps. The method was outpatient follow-up. Postoperative follow-up lasted until July 2022. The check-items for follow-up included: occurrence of necrosis, appearance, shape and texture of the flap, appearance of the reconstructed nails, TPD of the reconstructed digit pulps, tolerance to cold on the scars of flaps, flexion and extension of the reconstructed digits. The healing time of phalanges of the reconstructed digits was evaluated by X-rays. The appearance, sensation, the tolerance to cold of great toe and the movement of donor foot were also assessed.Results:Postoperative follow-up lasted for 18 to 24 months, with an average of 21 months. A total of 128 flaps survived. Necrosis occurred in 1 fibular hallux flap, the necrosis was cured with a reverse digital proper artery island flap. Thereafter, all flaps healed well. The appearance, shape, texture and nails of reconstructed digits were close to the contralateral digits. The reconstructed thumb and finger were evaluated according to Zook, 127 cases were excellent and 2 cases were good.TPD of the pulps of the reconstructed digits was 4-10 mm. The mean score of the Vancouver scar scale(VSS) was 0.6 for scars of the reconstructed digits. The mean score of the Visual analog scale(VAS) was 0.3 for the tolerance to cold. Flexion and extension function recovered well in all the reconstructed digits. According to the Evaluation Criteria of Upper limb Function Hand Surgery Society of Chinese Medical Association, the function of hand was excellent in 127 cases and 1 in each of good and fair. X-rays of all digits showed the phalange healing of the reconstructed digits, with an average healing time of 2 months after surgery, without phalange resorption, infection, nonunion nor stress fracture. There was no difference between the length of the donor great toe and the contralateral toe, except the donor site of the great toe nail root. There was no significant visual difference between the appearance of the donor great toe and the contralateral toe. TPD of the pulps of donor great toe was 4-8 mm. The mean score of the VSS was 1.4 for scars in the donor great toe. The mean score of the VAS was 0.7 for the tolerance to cold of the donor great toe. There was no stress fracture at donor site, and the functions of donor foot were not affected when walking, running, jumping and tiptoeing in all patients.Conclusion:It is an ideal method for reconstructing a partial defect of distal segment of digit by great toe flap. It can not only reconstruct the partial defect of distal segment of the digit, but also results in a good appearance and satisfactory functions of the reconstructed digit. Damage to the donor site is minimum. The length of the donor great toe is unchanged, and it has little impact on sensation and appearance of the donor great toe. Meanwhile, there is no adverse effect on walking, running and jumping with the donor foot.
