Objective:To explore the effect of ubiquitin-specific protease 42(USP42)on osteogenic differentiation of human adipose-derived stem cells(hASCs)in vivo and in vitro.Methods:A combina-tion of experiments was carried out with genetic depletion of USP42 using a lentiviral strategy.Alkaline phosphatase(ALP)staining and quantification,alizarin red S(ARS)staining and quantification were used to determine the osteogenic differentiation ability of hASCs under osteogenic induction between the experimental group(knockdown group and overexpression group)and the control group.Quantitative re-verse transcription PCR(qRT-PCR)was used to detect the expression levels of osteogenesis related genes in the experimental group and control group,and Western blotting was used to detect the expression levels of osteogenesis related proteins in the experimental group and control group.Nude mice ectopic im-plantation experiment was used to evaluate the effect of USP42 on the osteogenic differentiation of hASCs in vivo.Results:The mRNA and protein expressions of USP42 in knockdown group were significantly lower than those in control group,and those in overexpression group were significantly higher than those in control group.After 7 days of osteogenic induction,the ALP activity in the knockdown group was sig-nificantly higher than that in the control group,and ALP activity in overexpression group was significantly lower than that in control group.After 14 days of osteogenic induction,ARS staining was significantly deeper in the knockdown group than in the control group,and significantly lighter in overexpression group than in the control group.The results of qRT-PCR showed that the mRNA expression levels of ALP,os-terix(OSX)and collagen type Ⅰ(COL Ⅰ)in the knockdown group were significantly higher than those in the control group after 14 days of osteogenic induction,and those in overexpression group were signifi-cantly lower than those in control group.The results of Western blotting showed that the expression levels of runt-related transcription factor 2(RUNX2),OSX and COL Ⅰ in the knockout group were significant-ly higher than those in the control group at 14 days after osteogenic induction,while the expression levels of RUNX2,OSX and COL Ⅰ in the overexpression group were significantly lower than those in the control group.Hematoxylin-eosin staining of subcutaneous grafts in nude mice showed that the percentage of osteoid area in the knockdown group was significantly higher than that in the control group.Conclusion:Knockdown of USP42 can significantly promote the osteogenic differentiation of hASCs in vitro and in vi-vo,and overexpression of USP42 significantly inhibits in vivo osteogenic differentiation of hASCs,and USP42 can provide a potential therapeutic target for bone tissue engineering.

Objective:To evaluate whether index of microcirculatory resistance(IMR)is associated with left ventricular(LV)remodeling in acute anterior ST elevation myocardial infarction(STEMI)pa-tients undergoing primary percutaneous coronary intervention(PPCI).Methods:This was a single-center retrospective cohort study.The patients with first anterior STEMI who received PPCI from January 2014 to August 2017 in Peking University Third Hospital was enrolled.After PPCI,IMR was measured immediately by using pressure/temperature guidewire.The success rate of IMR measurement was 100％.Also we collected some related clinical data from the medical records and laboratory results.Infarct size[assessed as creatine kinase(CK)peak],echocardiography at baseline and 1 year follow-up were as-sessed.LV adverse remodeling(LVAR)was defined as ≥20％increase in LV end-diastolic volume(LVEDV).Results:A total of forty-three patients were enrolled,with an average age of(58.7±12.4)years.The patients were divided into two groups as IMR ≤25 and IMR＞25 by normal values recommen-ded by previous literature.Compared with IMR ≤25 group,IMR＞25 group had a higher percentage of initial thrombolysis in myocardial infraction(TIMI)grade 0(95.7％vs.65.0％,P=0.029),higher serum CK peak value[4 090(383,15 833)vs.1 580(396,5 583),P=0.004].The IMR＞25 group suffered higher rates of ventricular aneurysm(30.4％vs.5.0％,P=0.021).There was no difference in LVEDV[(111.0±18.8)mL vs.(115.0±23.6)mL,P=0.503]between the two groups 1 day after MI,but after 1 year,LVEDV in IMR＞25 group was significantly higher than in IMR≤25 group[(141.5± 33.7)mLvs.(115.9±27.9)mL,P=0.018].The incidence of LVAR was more significant in IMR＞25 group(47.4％vs.11.8％,P=0.024).Binary Logistics regression showed that IMR[B=0.079,exp(B)(95％CI)=1.082(1.018-1.149),P=0.011]and serum triglyceride level[B=1.610,exp(B)(95％CI)=5.005(1.380-18.152),P=0.014]were the predictors of LVAR 1 year after MI.IMR had a good predictive value for LVAR 1 year after MI[area under the curve(AUC)=0.749,P=0.019],IMR＞29 was a good cutoff value with sensitivity 81.8％and specificity 68.0％.Conclusion:Our study elaborates that immediate measurement of IMR after PPCI in patients with STEMI can reflect the microvas-cular function.And IMR could be used as a quantitative biomarker to predict LVAR after STEMI.

Objective:To explore the potential categories and influencing factors of family resilience of breast cancer patients based on potential profile analysis to provide reference for targeted intervention.Methods:Cross-sectional investigation was used. From January 2022 to June 2023, 268 breast cancer patients revisited in the outpatient department or ward of the Second Affiliated Hospital of Guilin Medical College and Nanxishan Hospital of Guangxi Zhuang Autonomous Region were selected as the study objects. The subjects were investigated by general data questionnaire, Family Resilience Assessment Scale, Medical Coping Style Questionnaire and Perceptive Social Support Scale. Potential profile analysis was used to identify the potential categories of family resilience in breast cancer patients, and ordered multiple Logistic regression analysis was used to determine the influencing factors of family resilience.Results:Totally 268 cases of breast cancer, aged 30-65 (49.51 ± 3.23) years old; the total score of family resilience was (81.78 ± 13.71) points. The family toughness of breast cancer patients could be divided into three potential profiles: low toughness and low coping difficulty group (23.1%), medium toughness and medium coping difficulty group (33.2%), high toughness and high coping difficulty group (43.7%). The results of ordered multiple Logistic regression analysis showed that residence, per capita monthly household income, medical coping style and perceived social support had an impact on the potential categories of family resilience in breast cancer patients (all P<0.05). Conclusions:There is group heterogeneity in family resilience of breast cancer patients. Medical staff should pay attention to the classification of patients in different places of residence and family per capita monthly income, and formulate personalized and precise interventions from the aspects of coping styles and social support to improve family resilience.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Background::Ainuovirine (ANV) is a new generation of non-nucleoside reverse transcriptase inhibitor for the treatment of human immunodeficiency virus (HIV) type 1 infection. This study aimed to evaluate the population pharmacokinetic (PopPK) profile and exposure-response relationship of ANV among people living with HIV.Methods::Plasma concentration-time data from phase 1 and phase 3 clinical trials of ANV were pooled for developing the PopPK model. Exposure estimates obtained from the final model were used in exposure-response analysis for virologic responses and safety responses.Results::ANV exhibited a nonlinear pharmacokinetic profile, which was best described by a two-compartment model with first-order elimination. There were no significant covariates correlated to the pharmacokinetic parameters of ANV. The PopPK parameter estimate (relative standard error [%]) for clearance adjusted for bioavailability (CL/F) was 6.46 (15.00) L/h, and the clearance of ANV increased after multiple doses. The exposure-response model revealed no significant correlation between the virologic response (HIV-RNA <50 copies/mL) at 48 weeks and the exposure, but the incidence of adverse events increased with the increasing exposure ( P value of steady-state trough concentration and area under the steady-state curve were 0.0177 and 0.0141, respectively). Conclusions::Our PopPK model supported ANV 150 mg once daily as the recommended dose for people living with HIV, requiring no dose adjustment for the studied factors. Optimization of ANV dose may be warranted in clinical practice due to an increasing trend in adverse reactions with increasing exposure.Trial registration::Chinese Clinical Trial Registry https://www.chictr.org.cn (Nos.
