Aromataseinhibitors(AI)aretheleadingcarefortheadjuvanttreatmentofhormone responsive carcinoma of the breast as demonstrated in a number of large international phase III randomised tri-als.Aromatase inhibitor-associated arthralgia (AIA )was a somewhat unexpected side effect of this class of agents and has proven to be potentially problematic in clinical practice.The pathogenesis of AIA is not very clear currently,with the cause of most research focusing on estrogen deprivation,immune abnormalities,tenosy-novial changes and joint effusions.It is extremely urgent that we evaluate this syndrome and select appropriate therapeutic strategies to reduce the incidence of AIA,thereby improving breast cancer-related outcomes.

BACKGROUND:With the proven ability of traditional Chinese medicine such as icariin and berberine to promote bone regeneration by regulating various mechanisms and targets,researchers have combined active ingredients of traditional Chinese medicine with bone tissue engineering and found that they have unique advantages in treating bone defects. OBJECTIVE:Starting from the active ingredients of traditional Chinese medicines that promote bone formation,to screen cases of their effective combination with different drug-carrying scaffold materials,and summarize the active ingredients of traditional Chinese medicines that have the potential to be applied to bone tissue engineering. METHODS:CNKI,WanFang,PubMed,and Web of Science were searched for relevant literature published from 2000 to 2023,using the keywords of"bone tissue engineering,bone tissue-engineered scaffold materials,bone defect,bone repair,bone regeneration,traditional Chinese medicine"in Chinese and English.According to the inclusion and exclusion criteria,87 papers were finally included for review. RESULTS AND CONCLUSION:There are various kinds of active ingredients of traditional Chinese medicine to promote bone regeneration,mainly including flavonoids,non-flavonoid polyphenols,alkaloids,glycosides.These active ingredients have anti-inflammatory and analgesic effects,promote osteoblasts,inhibit osteoclasts and promote early angiogenesis.The combination of active ingredients of traditional Chinese medicine with bone tissue engineering is effective in anti-inflammation,accelerating collagen and bone formation,and promoting the expression of osteogenic genes,which provides a theoretical basis for the application of traditional Chinese medicine in bone tissue regeneration,and at the same time provides a new idea for the repair of bone defects.

Prevention and control of scoliosis and myopia co-morbidity should start with students behavioral habits, early screening and early intervention.

Hispidin is an important styrylpyrone produced by Sanghuangporus sanghuang. To analyze hispidin biosynthesis in S. sanghuang, the transcriptomes of hispidin-producing and non-pro ducing S. sanghuang were determined by Illumina sequencing. Five PKSs were identified using genome annotation. Comparative analysis with the reference transcriptome showed that two PKSs (ShPKS3 and ShPKS4) had low expression levels in four types of media. The gene expression pattern of only ShPKS1 was consistent with the yield variation of hispidin. The combined analyses of gene expression with qPCR and hispidin detection by liquid chro matography-mass spectrometry coupled with ion-trap and time-of-flight technologies (LCMS-IT-TOF) showed that ShPKS1 was involved in hispidin biosynthesis in S. sanghuang.ShPKS1 is a partially reducing PKS gene with extra AMP and ACP domains before the KS domain. The domain architecture of ShPKS1 was AMP-ACP-KS-AT-DH-KR-ACP-ACP. Phylogenetic analysis shows that ShPKS1 and other PKS genes from Hymenochaetaceae form a unique monophyletic clade closely related to the clade containing Agaricales hispidin synthase. Taken together, our data indicate that ShPKS1 is a novel PKS of S. sanghuang involved in hispidin biosynthesis.

Objective? Systematic review and meta-analysis were used to explore the effect of sodium and water restriction on improving cardiac function (symptom score of heart failure and B-type natriuretic peptide were used as evaluation indexes) in patients with heart failure. Methods? Pubmed,CIHNAL,Embase and other foreign language databases,as well as Wanfang,CNKI and other Chinese language databases were searched and studies of randomized controlled trials(RCT)applying sodium and water restriction in the improvement of cardiac function in patients with heart failure published by March 2019 were included for systematic review and meta-analysis. Results? A total of 12 English literatures were included,of which,5 were Grade A and 7 were Grade B for study quality. Meta-analysis based on the heart failure score with water and sodium restriction showed that the symptoms of heart failure patients with sodium restriction (≤1.5 g/d) were relieved more obviously than those with sodium restriction above that level or without sodium restriction [SMD=0.50, 95%CI=(0.16, 0.83)]; for those with the level of sodium restriction lower than 0.8-3.0 g/d combined with fluid restriction below 800-1 500 ml/d, compared with those who did not met the criteria or those without sodium restriction, the heart failure symptom scores decreased without significance [SMD=-0.18,95%CI=(-0.43,0.08)]. Moreover, in each study, B-type natriuretic peptide was mostly non-normal data, which was not suitable for Meta-analysis. Descriptive analysis showed that two studies showed that B-type natriuretic peptide could be significantly reduced under 2.3 g/d sodium restriction and 1 000 ml/d water restriction,respectively. The other studies had negative results in the studies of water and sodium restriction in changing B-type natriuretic peptide. Conclusions? The daily sodium restriction of 1.5 g has a significant effect on the improvement of cardiac function in patients with acute heart failure or edema symptoms. The daily sodium restriction of 1 000 ml has a significant effect on the improvement of cardiac function in patients with decompensated heart failure.

Iliac vein stenosis (IVS), known as iliac vein compression syndrome, refers to a series of diseases caused by iliac vein compression or intraluminal adhesions leading to lower extremity vein or pelvic vein drainage disturbance and other clinical manifestations which is quite common in vascular surgery. The vast majority of patients with symptoms of chronic venous insufficiency (CVI) have IVS. In clinical work, IVS does not typically appear as a single symptom, while often combining with other lesions, such as varicose veins of the lower extremities, skin pigmentation, ulcer formation. Studies on its aetiology and epidemiology have found a mean age of onset of 40 years, the age of onset in females is lower than that in males, and the average of stress in females is significantly higher than that in males. Typical IVS occurs mainly in the left lower extremity in young women of reproductive age, but exceptions remain. In summary, the importance of the diagnosis of IVS in clinical practical work can be seen. CVI is a general term for all diseases that affect the morphology and function of the venous system. Compared with chronic venous disease (CVD), CVI include venous system abnormalities without symptoms or signs. Thus, it more accurately describes the diagnosis and treatment of IVS that requires clinical guidance, so its concept is quoted. With the development and advancement of medical imaging, more and more techniques provide help in the diagnosis and treatment of IVS. Therefore, professionals in various specialties have made relevant studies about the benefits and drawbacks of imaging techniques for diagnosis, treatment modalities, and prognostic management of this disease, in order to improve the diagnostic efficacy. Consequently, this review is focused on the current situation of the diagnosis and treatment of IVS under multi-modal imaging, hoping to provide choices of medical imaging technologies for the different states, and to find a better and personalized plan for patients.

Objective:To evaluate the effects of endothelial progenitor cell (EPC)-derived exosomes on neuronal injury induced by oxygen-glucose deprivation and restoration (OGD/R).Methods:HT22 neurons of mice were cultured and divided into 3 groups ( n=30 each) using a random number table method: control group (C group), OGD/R group and OGD/R plus EPC-derived exosome group (OGD/R+ EXO group). Cells in group C were cultured in normal atmosphere.In group OGD/R, the cells were exposed to 94%N 2-1%O 2-5%CO 2 for 6 h in glucose- and serum-free DMEM medium, followed by 24 h restoration of O 2 and glucose in the normal medium.In group OGD/R+ EXO, 20 μg/ml EPC-derived exosomes were added to the culture medium at 24 h before developing the model.EPCs were identified by immunofluorescence staining.Exosomes were identified by Western blot, transmission electron microscopy (TEM) and nanoparticle tracking analysis (NTA). Cell viability was measured by CCK-8 assay, the levels of malondialdehyde (MDA) and superoxide dismutase (SOD) were determined by enzyme-linked immunosorbent assay.The neuronal apoptosis was detected by TUNEL staining, and the apoptosis rate was calculated.The expression of Bax, Bcl-2, caspase-3, and cleaved caspase-3 was determined by Western blot, and cleaved caspase-3/caspase-3 ratio was calculated. Results:The cultured cells were EPCs, and EPC-derived exosomes were successfully extracted.Compared with group C, the cell viability was significantly decreased, the content of MDA was increased, the activity of SOD was decreased, the apoptosis rate was increased, the expression of Bax was up-regulated, the expression of Bcl-2 was down-regulated, and the ratio of cleaved-caspase-3/caspase-3 was increased in group OGD/R and group OGD/R+ EXO ( P<0.05). Compared with group OGD/R, the cell viability was significantly increased, the content of MDA was decreased, the activity of SOD was increased, the apoptosis rate was decreased, the expression of Bax was down-regulated, the expression of Bcl-2 was up-regulated, and the ratio of cleaved-caspase-3/caspase-3 was decreased in group OGD/R+ EXO ( P<0.05). Conclusions:EPC-derived exosomes can reduce OGD/R-induced neuronal injury, which is related to inhibition of oxidative stress and neuronal apoptosis.

Objective:To explore the characteristics and typology of self-care behavior among patients with chronic heart failure (CHF), and analyze their influencing factors.Methods:A cross-sectional study was used. A total of 318 patients with CHF who were hospitalized in the Heart Center of Zhongshan Hospital, Fudan University from November 2022 to July 2023 were selected by continuous enrollment method. The General Information Questionnaire, Heart Failure Self-care Index Scale, Brief Illness Perception Questionnaire, Self-efficacy for Managing Chronic Disease 6-item Scale, Perceived Social Support Scale, Atlanta Heart Failure Knowledge Test-V2 and Self-Care Confidence Scale were used to investigate. Latent profile analysis was utilized to delineate the characteristics and subtypes of self-care behaviors in CHF patients and examine the influencing factors.Results:A total of 291 patients were included in this study, including 190 males and 101 females, aged 67 (61, 74) years old. The analysis identified three latent categories of self-care behaviors among CHF patients: 26 cases in high self-care group, 131 cases in moderate self-care with deficiencies in maintenance and symptom perception group, and 134 cases in low self-care group.Ordered multicategorical Logistic regression analysis revealed that age ( OR=1.023, 95% CI 1.001-1.046, P<0.05), self-care confidence ( OR=0.859, 95% CI 0.817-0.904, P<0.01), and social support ( OR=0.966, 95% CI 0.940-0.993, P<0.05) were the factors influencing the potential categories of self-care behavior in CHF patients. Conclusions:The study identifies distinct categorical characteristics of self-care behaviors in patients with CHF. Healthcare professionals can leverage these findings to identify the self-care behavior characteristics and influencing factors for each patient category at an early stage, thereby providing personalized and precise support strategies to help patients enhance self-care behaviors.

Objective To evaluate the efficacy of Schroth PSSE combined with 3D printing braces in the treatment of adolescent idiopathic scoliosis.Method Forty patients were included and divided into a support group(3D printing support group)and a support+exercise therapy group(3D printing support+Schroth PSSE group).Excluding outliers and lost follow-up data,32 patients were ultimately included,with 16 patients in each group.Wearing time≥18 h for both groups of 3D printing supports.The intervention period of Schroth PSSE is 12 weeks,and exercise is maintained after 12 weeks until the end of follow-up.The longest follow-up time for the brace group was 25 months,with an average follow-up time of(15.00±1.29)months.The longest follow-up time for the brace+exercise therapy group was 24 months,with an average follow-up time of(16.59±1.01)months.Relevant indicators were evaluated after follow-up.Results The support and exercise therapy group showed better improvement in Cobb angle and trunk rotation angle(ATR)than the support group,with statistically significant differences(P<0.05);The distance between the midpoint of the C7 vertebral body and the midline of the sacrum(C7-CSVL)in the support and exercise therapy group showed a statistically significant difference before and after treatment(P<0.05),while there was a significant difference before and after Apical Vertebral Translation(AVT)treatment(P<0.01).There was no statistically significant difference compared to the support group(P<0.05);In terms of SRS-22 score,the brace+exercise therapy group can comprehensively improve the SRS-22 score.Conclusion The combination of Schroth PSSE and 3D printing braces has a better effect on improving Cobb angle and torso rotation angle,improving coronary imbalance,increasing patient satisfaction,and improving quality of life compared to using 3D printing braces alone.
