Osteoarthritis （OA） is characterized by articular cartilage degeneration， synovial hyperplasia， hyperosteogeny， and narrowing of joint space， which can be caused by trauma， inflammation， and other factors. With the increasing global population aging， the incidence of OA is rising year by year， making it a major public health problem that urgently needs to be addressed. Exploring effective treatment schemes is particularly important. The pathogenesis of OA is complex， including oxidative stress， autophagy， and apoptosis. Recent studies have found that ferroptosis， a new type of cell death， is also an important pathogenic factor in OA， characterized by a series of complex changes such as iron ion accumulation， glutathione （GSH） depletion， and mitochondrial dysfunction. Research shows that inhibiting ferroptosis in chondrocytes can promote chondrocyte proliferation， delay extracellular matrix （ECM） degradation， and reduce synovial hyperplasia and inflammation. Targeting ferroptosis is a new direction in the treatment of OA. OA treatment includes intra-articular injections of steroids or hyaluronic acid and artificial joint replacement， but there are limitations. Traditional Chinese medicine （TCM） has been widely used in the treatment of various diseases because of its low cost， low drug resistance， and few side effects. Cell and animal experiments have further confirmed that TCM can intervene in the treatment of OA with ferroptosis from multiple targets， multiple levels， and aspects， but the mechanism of its treatment of OA based on ferroptosis has not been clarified. This paper discussed iron metabolism， lipid peroxidation， cysteine/glutamate transporter system Xc^- （system Xc^-）/GSH/glutathione peroxidase 4 （GPX4） pathway， nicotinamide adenine dinucleotide phosphate（NADPH）/ferroptosis suppressor protein 1 （FSP1）/coenzyme Q₁₀ （CoQ₁₀） pathway， tumor protein p53 in OA， and related molecular targets of Chinese medicine monomers and compounds on ferroptosis inhibition. Their potential therapeutic mechanisms were further analyzed to provide theoretical guidance for the treatment of OA by TCM and useful reference for the research and development of related drugs.

Objective:To conduct a scoping review of research on the self-advocacy of adult cancer patients to identify their self-advocacy needs, behaviors, strengths and weaknesses, so as to provide guidance for future research in this field.Methods:Using the scoping review guidelines of Joanna Briggs Institute in Australia as a methodological framework, relevant literatures were searched in PubMed, Web of Science, Cochrane Library, Embase, Science Direct, CINAHL, Scopus, China National Knowledge Infrastructure, Wanfang, VIP and China Biology Medicine disc. The search period was from establishment of the databases to December 2023, and the results were summarized and analyzed.Results:A total of 14 articles were included, and self-advocacy needs included six types of needs, such as symptom management, communication, interpersonal support, disease information, decision-making and emotional management. Self-advocacy included four aspects, including seeking information, self-decision-making, strengthening contact with the outside world and effective communication.Conclusions:Adult cancer patients have diverse types of self-advocacy needs and certain self-advocacy behaviors. Future research should pay attention to self-advocacy needs assessment, develop corresponding tools, focus on self-advocacy behaviors, leverage the advantages of self-advocacy and explore strategies to achieve effective self-advocacy support.

Skeletal muscle wasting refers to a loss of skeletal muscle mass and function.Mitochondrial quality control(MQC)is the basis by which normal physiological mitochondrial function is maintained and mainly involves the regulation of mitochondrial biogenesis,mitochondrial dynamics(fission/fusion),and mitophagy.MQC maintains muscle homeostasis by regulating the relative stability of mitochondrial shape,quantity,and quality.As an economical and effective treatment for muscular atrophy,exercise interventions are widely used,but the relationship between exercise intervention and MQC is not clear.This paper discusses the role of mitochondrial biogenesis,mitochondrial dynamics,and mitophagy in skeletal muscle atrophy and related molecular targets.We thoroughly analyze the mechanisms by which MQC-mediated exercise can improve the skeletal muscle atrophy caused by aging,disuse,and cancer cachexia in order to provide theoretical guidance for intervention.

Objective:To assess the efficacy of parent training (PT) on attention deficit hyperactivity disorder (ADHD) symptoms, behavioral problems, and parenting stress in child with ADHD or ADHD symptoms.Methods:Randomized controlled trials of the effect of PT on ADHD symptoms in Chinese children with ADHD or ADHD symptoms were collected by PsychINFO, PubMed, EMBASE, Web of science, Scopus, China National Knowledge database, WanFang database, the China Science and Technology Journal Database and the China Biology Medicine disc. The quality of the included studies was evaluated by version 2 of the Cochrane tool for assessing risk of bias in randomized trial. Forest plots were drawn using Review Manager 5.4.1, sensitivity analyses of results were performed using Stata 18.0 to assess the stability of the results, and publication bias was assessed using funnel plots and Egger's test.Results:A total of 10 studies containing 571 subjects in the experimental group and 562 subjects in the control group met the inclusion exclusion criteria. Significant differences were observed in various measures, including overall ADHD symptoms (MD=-2.43, 95% CI: -3.95--0.91), inattention (MD=-1.10, 95% CI: -1.94--0.26), hyperactivity/impulsivity (SMD=-0.58, 95% CI: -0.87--0.28), overall conduct problems (SMD=-0.80, 95% CI: -1.05--0.55), conduct problem (SMD=-1.34, 95% CI: -2.31--0.37), learning problem (SMD=-0.81, 95% CI: -1.40--0.23), impulsivity/hyperactivity (SMD=-0.53, 95% CI: -0.78--0.29), hyperactivity index (SMD=-1.27, 95% CI: -1.99--0.55), parenting stress index (SMD=-0.69, 95% CI: -1.12--0.26), difficult child (MD=-1.96, 95% CI: -3.44--0.48), dysfunctional interaction (MD=-3.10, 95% CI: -4.43--1.78), and parenting distress (MD=-3.35, 95% CI: -4.59--2.12)(all P<0.05). However, no significant differences were observed in oppositional-defiant disorder, anxiety, or somatic problem. Conclusions:The initial findings suggested that PT was effective for Chinese children with ADHD or ADHD symptoms.The addition of PT appeared to improve core symptoms of ADHD (inattention and hyperactivity/impulsivity), conduct problems, and parental stress more effectively than routine care alone.

OBJECTIVE: To assess the efficacy and safety of Guanxin Danshen Dripping Pills (GXDS) in the treatment of depression or anxiety in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI). METHODS: From September 2017 to June 2019, 200 CHD patients after PCI with depression and anxiety were included and randomly divided into GXDS (100 cases) and placebo control groups (100 cases) by block randomization and a random number table. Patients in the GXDS and control groups were given GXDS and placebo, respectively, 0.4 g each time, 3 times daily for 12 weeks. The primary outcomes were scores of Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Scale (GAD-7) and the Seattle Angina Pectoris Scale (SAQ). The secondary outcomes included 12 Health Survey Summary Form (SF-12) scores and the first onset time and incidence of major adverse cardiovascular events (MACEs). Other indices including blood pressure, blood lipids, microcirculation and inflammatory-related indices, etc. were monitored at baseline, week 4, and week 12. RESULTS: In the full analysis set (200 cases), after treatment, the PHQ-9 and GAD-7 scores in the GXDS group were considerably lower than those in the control group (P<0.05). Compared with the baseline, the total PHQ-9 scores of the experimental and control groups decreased by 3.97 and 1.18, respectively. The corrected mean difference between the two groups was -2.78 (95% CI: -3.47, -2.10; P<0.001). The total GAD-7 score in the GXDS group decreased by 3.48% compared with the baseline level, while that of the placebo group decreased by 1.13%. The corrected mean difference between the two groups was -2.35 (95% CI: -2.95, -1.76; P<0.001). The degree of improvement in SAQ score, SF-12 score, endothelin and high-sensitive C-reactive protein levels in the GXDS group were substantially superior than those in the placebo group, and the differences between the two groups were statistically significant (P<0.05). Similar results were obtained in the per protocol population analysis of 177 patients. Three cases of MACES were reported in this study (1 in the GXDS group and 2 in the placebo group), and no serious adverse events occurred. CONCLUSIONS GXDS can significantly alleviate depression and anxiety, relieve symptoms of angina, and improve quality of life in patients with CHD after PCI. (Registration No. ChiCTR1800014291).

Objective To investigate the release of enterogenic and hepatogenic high mobility group protein B1(HMGB1)through exosomes and its regulatory pathway.Methods We used wild-type(WT)and ASC-/-mice for this study.We randomly selected five mice per group from each strain and fed them either a normal diet(ND)or a high-fat diet(HFD)for eight weeks.The control group consisted of WT mice fed with the normal diet;the HFD group were WT mice with the HFD;the microflora disturbance(MD)group were ASC-/-mice fed with the normal diet;the high-lipid microflora disturbance(HLMD)group were ASC-/-mice with HFD.We used confocal microscopy to detect the co-localization of liver and intestinal exosome markers with HMGB1.We then measured the expression level of HMGB1 content in exosomes by Western blotting and PCR.The AML12 cells were treated with palmitic acid(PA)and lipopolysaccharide(LPS)for 24 h to build an in vitro model.We also detected HMGB1/CD63 levels using Western blotting.To understand the regulatory mechanism of exosome release,we employed siRNA intervention.Results The secretion of exosomes increased significantly in HFD group compared with control group[(3.5±0.2)ng/ml vs.(1.1±0.3)ng/ml,P<0.05],HLMD group compared with those in MD group[(3.2±0.2)ng/ml vs.(1.9±0.4)ng/ml,P<0.05].Using immunofluorescence detection,we observed increased co-localization of exosome markers(ALP or VPS16)with HMGB1 in HFD group compared with control group.We also observed this in AML12 cells treated with PA and LPS compared with blank control.The PCR data showed that HMGB1 in hepatocyte exosomes was higher in HFD group compared with control group(41.5±10.2 vs.1.3±0.3,P<0.05),HLMD group was significantly higher than that in MD group(48.6±7.2 vs.1.5±0.5,P<0.05).TLR4 expression was higher in HFD group compared with control group(13.8±6.2 vs.2.8±0.9,P<0.05),HLMD group compared with MD group(22.6±4.1 vs.2.5±1.5,P<0.05).In intestinal mucosal cells,the co-location of HMGB1 and exosome marker CD63 was significantly higher in HFD group compared with control group(0.6±0.2 vs.0.4±0.1,P<0.05),and HLMD group compared with MD group(0.9±0.2 vs.0.5±0.1,P<0.05).In vitro,the HMGB1 of exosomes was increased in endotoxin group(5.1±0.8)and high lipid endotoxin group(5.5±0.7)compared with control group(3.8±0.6,P<0.05).On the other hand,the HMGB1 of exosomes in the cell siRNA intervention group was not increased compared with control group(3.7±0.6 vs.3.8±0.6,P>0.05).Conclusion HMGB1 is released by exosomes in hepatocytes and intestinal cells,and regulated by Toll-like receptor 4(TLR4)under a high-fat diet and intestinal flora disorder,which may be one of the contributing factors in promoting the development of steatohepatitis.

OBJECTIVE: To analyze the efficacy of children with B-cell acute lymphoblastic leukemia (B-ALL) without prognostic fusion genes treated by CCLG-ALL 2008, and investigate the related factors affecting the recurrence of the patients. METHODS: B-ALL patients without prognostic fusion genes treated by the protocol of CCLG-ALL 2008 in our hospital from March 2008 to December 2012 were retrospectively analyzed. Follow-up time was ended in August 31, 2019. The median follow-up time was 92 months (range 0-136 months). Kaplan-Meier was used to detect the RFS, and COX multivariate regression analysis was employed to identify the independent factors affecting the recurrence of the patients. RESULTS: There were 140 males and 99 females enrolled in this study. The ratio of male to female was 1.41∶1. The median age was 4.4 years old and the median number of WBC at initial stage was 4.98×10⁹/L. There were 77 cases relapsed during the observation while 162 without relapsed, 16 cases lost to follow-up and 72 cases died. The recurrence and mortality rate was 32.22% and 30.1%, respectively, in which 45 cases died of recurrence (62.5% of the total deaths). Univariate analysis showed that the age≥6 years old, WBC >100×10⁹/L, the bone marrow blasts on day 15≥25%, the bone marrow minimal residual disease (MRD) at week 12 >10^-4, and the higher risk were the main factors affecting the recurrence of the patients (P<0.05). Multivariate COX regression analysis showed that age≥6 years old, WBC >100×10⁹/L, bone marrow MRD >10^-4 at the 12th week were the independent risk factors affecting recurrence of the patients. CONCLUSION Age, initial WBC, and bone marrow MRD at the 12th week were correlated with recurrence in children with B-ALL without prognostic fusion genes, which can be used as prognostic indices of recurrence risk in clinical.

Objective To study the intestinal absorption characteristics of apixaban in rats with renal failure, and the effect of P-glycoprotein (P-gp) inhibitors on its absorption behavior. Methods The in vivo absorption experiment was performed in CRF rats by one-way perfusion method and the absorption factors was investigated by establishing the HPLC analysis method. Results The absorption rate constant (K_a) of apixaban in each intestinal segment was significantly different (P<0.05) with no significant difference in apparent absorption coefficient (P_app) (P>0.05). The K_a and P_app values in the rat ileum decreased with the increasing of drug concentration. After addition of P-gp inhibitor verapamil hydrochloride (0.1 mmol/L), the K_a and P_app values of apixaban in the jejunum and ileum were significantly increased. Conclusion Apixaban is absorbed in all intestinal segments. P-gp inhibitors can significantly promote the absorption of apixaban in jejunum and ileum, suggesting that apixaban is P-gp substrate and its absorption mechanism is supposed to be active transport.

The Solanaceae plants distributed in China belong to 105 species and 35 varietas of 24 genera. Some medicinal plants of Solanaceae are rich in tropane alkaloids(TAs), which have significant pharmacological activities. In this paper, the geographical distribution, chemical components, traditional therapeutic effect, pharmacological activities, and biosynthetic pathways of TAs in Solanaceous plants were summarized. Besides, the phylogeny of medicinal plants belonging to Solanaceae was visualized by network diagram. Fourteen genera of Solanaceae plants in China contain TAs and have medical records. TAs mainly exist in Datura, Anisodus, Atropa, Physochlaina, and Hyoscyamus. The TAs-containing species were mainly concentrated in Southwest China, and the content of TAs was closely related to plant distribution area and altitude. The Solanaceae plants containing TAs mainly have antispasmodic, analgesic, antiasthmatic, and antitussive effects. Modern pharmacological studies have proved the central sedative, pupil dilating, glandular secretion-inhibiting, and anti-asthma activities of TAs. These pharmacological activities provide a reasonable explanation for the traditional therapeutic efficacy of tropane drugs. In this paper, the geographical distribution, chemical components, traditional therapeutic effect, and modern pharmacological activities of TAs-containing species in Solanaceae were analyzed for the first time. Based on these data, the genetic relationship of TAs-containing Solanaceae species was preliminarily discussed, which provided a scientific basis for the basic research on TAs-containing solanaceous species and was of great significance for the development of natural medicinal plant resources containing TAs.
