This study aims to explore the protective effect of Chaihu Jia Longgu Muli Decoction on rats with heart failure after myocardial infarction, and to clarify its possible mechanisms, providing a new basis for basic research on the mechanism of classic Chinese medicinal formula-mediated inflammatory response in preventing and treating heart failure induced by apoptosis after myocardial infarction. A heart failure model after myocardial infarction was established in rats by coronary artery ligation. The rats were divided into sham group, model group, and low, medium, and high-dose groups of Chaihu Jia Longgu Muli Decoction, with 10 rats in each group. The low-dose, medium-dose, and high-dose groups of Chaihu Jia Longgu Muli Decoction were given 6.3, 12.6, and 25.2 g·kg~(-1) doses by gavage, respectively. The sham group and model group were given an equal volume of distilled water by gavage once daily for four consecutive weeks. Cardiac function was assessed using color Doppler echocardiography. Myocardial pathology was detected by hematoxylin-eosin(HE) staining, apoptosis was measured by TUNEL assay, and mitophagy was observed by transmission electron microscopy. The levels of tumor necrosis factor-α(TNF-α), interleukin(IL)-1β, and N-terminal pro-B-type natriuretic peptide(NT-proBNP) in serum were detected by enzyme-linked immunosorbent assay(ELISA). The expression of apoptosis-related proteins B-cell lymphoma 2(Bcl-2), Bcl-2-associated X protein(Bax), and cleaved caspase-3 was detected by Western blot. Additionally, the expression of phosphorylated nuclear transcription factor-κB(NF-κB) p65(p-NF-κB p65)(upstream) and nuclear factor kappa B inhibitor alpha(IκBα)(downstream) in the NF-κB signaling pathway was assessed by Western blot. The results showed that compared with the sham group, left ventricular ejection fraction(LVEF) and left ventricular short axis shortening(LVFS) in the model group were significantly reduced, while left ventricular end diastolic diameter(LVEDD) and left ventricular end systolic diameter(LVESD) increased significantly. Myocardial tissue damage was severe, with widened intercellular spaces and disorganized cell arrangement. The apoptosis rate was increased, and mitochondria were enlarged with increased vacuoles. Levels of TNF-α, IL-1β, and NT-proBNP were elevated, indicating an obvious inflammatory response. The expression of pro-apoptotic factors Bax and cleaved caspase-3 increased, while the anti-apoptotic factor Bcl-2 decreased. The expression of p-NF-κB p65 was upregulated, and the expression of IκBα was downregulated. In contrast, the Chaihu Jia Longgu Muli Decoction groups showed significantly improved of LVEF, LVFS and decreased LVEDD, LVESD compared to the model group. Myocardial tissue damage was alleviated, and intercellular spaces were reduced. The apoptosis rate decreased, mitochondrial volume decreased, and the levels of TNF-α, IL-1β, and NT-proBNP were lower. The expression of pro-apoptotic factors Bax and cleaved caspase-3 decreased, while the expression of the anti-apoptotic factor Bcl-2 increased. Additionally, the expression of p-NF-κB p65 decreased, while IκBα expression increased. In summary, this experimental study shows that Chaihu Jia Longgu Muli Decoction can reduce the inflammatory response and apoptosis rate in rats with heart failure after myocardial infarction, which may be related to the regulation of the IκBα/NF-κB signaling pathway.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

By using thioflavin T(ThT)as displacement-based fluorescent probes,three kinds of aptasensors were constructed for rapid detection of three kinds of small molecules such as ochratoxin A(OTA),aflatoxin B1(AFB1)and adenosine.In the absence of target molecule,ThT bound with the aptamer to form an aptamer-ThT complex and exhibited a significant fluorescence response.Upon the addition of target molecule,because of the higher affinity between target and aptamer than that between ThT and the aptamer,ThT was displaced by the target molecule from the aptamer-ThT complex,resulting in weakened fluorescence signal.Based on this principle,the target molecule could be detected quantitatively.Further study through circular dichroism spectra showed that there was no significant change in the conformation of the aptamer after addition of ThT or target molecules.The stoichiometric ratios of ThT to OTAapt,AFB1apt and Adeapt measured through the method of equimolar continuous variation was 1∶1,1∶1 and 2∶1,respectively,and their dissociation constants were all larger than those between the target molecule and its aptamer.Therefore,the principle of this detection method was the displacement of fluorescent probe(ThT)in aptamer-ThT complex by target molecule,resulting in decrease of fluorescence intensity.Under optimal experimental conditions,the limits of detection(LODs)were 0.8 nmol/L for OTA,1.3 nmol/L for AFB1,and 0.10 μmol/L for adenosine,respectively.This method was label-free,simple to operate,with low cost,good selectivity and high sensitivity.The developed assay kit based on this method could be used for actual sample detection.

The study explored the pathological mechanism of doxorubicin chemotherapy-induced neurotoxicity and the intervention methods of traditional Chinese medicine. BALB/c mice were selected to establish tumor-bearing mouse models by orthotopic injection of 4T1 triple-negative breast cancer cells. After randomization, the mice were treated with doxorubicin chemotherapy or doxorubicin chemotherapy + Kaixin San(KXS). The lesions in the prefrontal cortex of mice were observed by pathological examination, and the lesion information was obtained by long non-coding RNA sequencing. The occurrence of lesions was determined by Western blot and biochemical indicators. In addition, neuroblastoma cells and microglia cells were used to construct in vitro models, and drug-containing serum and p-AMPK dephosphorylation inhibitors were used to further verify the accuracy of animal experiments. Pathological results showed that KXS could alleviate doxorubicin-induced neuronal degeneration in the prefrontal cortex. The long non-coding RNA sequencing suggested that neuronal degeneration and the intervention process of KXS were related to ferroptosis, immune diseases, AMPK signaling pathway, etc. Western blot and biochemical indicators confirmed that this process was directly related to the activation of the AMPK/HIF-1α/ACSL4 signaling pathway to alleviate ferroptosis of neurons and immune response of glial cells. In conclusion, KXS could alleviate doxorubicin-induced neurotoxicity by activating the AMPK signaling pathway and reducing the ferroptosis of neurons and immune response of glial cells.

Aim To analyze the genotype-phenotype characteristics of voltage-gated potassium channels (Kv) associated genetic epilepsy and evaluate the efficacy of anti-seizure medications(ASMs). Methods PubMed database was searched and patients meeting the inclusion criteria were included for analysis. We divided the patients into “benign”, “encephalopathic” and other phenotypes according to the clinical characteristics. We performed descriptive statistical analysis of patients' mutated genes, clinical phenotype and drug efficacy, and used logistic regression to explore the influencing factors of treatment outcome. Results Data of 474 children were included for analysis. There were significant differences among different phenotypes in mutated genes, source of mutations and so on. In terms of clinical characteristics, there were also significant differences between patients with different phenotypes in age of onset, combined developmental delay and so on. In terms of monotherapy, phenobarbital was the most common treatment choice for children with “benign” phenotype, and sodium channel blockers (SCBs) were the most common treatment choice for children with “encephalopathy” phenotype, and the efficacy of SCBs monotherapy was superior to that of other ASMs. Multivariate Logistic analysis of the children receiving monotherapy showed that whether the children were combined with developmental delay and whether SCBs were used were significant factors influencing the efficacy of drug therapy. Conclusions Patients with the “benign” and “encephalopathic” phenotypes differ in several aspects of genetic variation, clinical characteristics, and drug selection. These results suggest that SCBs may be one of the recommended options for monotherapy.

To compare the impact of the scrotal vs inguinal orchidopexy approach on the testicular function of infants with cryptorchidism, a randomized controlled trial was conducted involving boys who were 6-12 months old at surgery and were diagnosed with clinically palpable, inguinal undescended testis. Between June 2021 and December 2021, these boys at Fujian Maternity and Child Health Hospital (Fuzhou, China) and Fujian Children's Hospital (Fuzhou, China) were enrolled. Block randomization with a 1:1 allocation ratio was employed. The primary outcome was testicular function assessed by testicular volume, serum testosterone, anti-Müllerian hormone (AMH), and inhibin B (InhB) levels. Secondary outcomes included operative time, amount of intraoperative bleeding, and postoperative complications. Among 577 screened patients, 100 (17.3%) were considered eligible and enrolled in the study. Of the 100 children who completed the 1-year follow-up, 50 underwent scrotal orchidopexy and 50 underwent inguinal orchidopexy. The testicular volume, serum testosterone, AMH, and InhB levels in both groups increased markedly after surgery (all P < 0.05), but there were no apparent differences between groups at 6 months and 12 months after operation (all P > 0.05). No differences between the scrotal and inguinal groups were noted regarding the operative time ( P = 0.987) and amount of intraoperative bleeding ( P = 0.746). The overall complication rate (2.0%) of the scrotal group was slightly lower than that of the inguinal group (8.0%), although this difference was not statistically significant ( P > 0.05). Both scrotal and inguinal orchiopexy exerted protective effects on testicular function in children with cryptorchidism, with similar operative status and postoperative complications. Scrotal orchiopexy is an effective alternative to inguinal orchiopexy in children with cryptorchidism.

For many years, surgical treatment of buried penis in children has been researched by several scholars, and numerous methods exist. This study aimed to explore the clinical effect of a modified fixation technique in treating buried penis in children. Clinical data of 94 patients with buried penis who were treated using the modified penile fixation technique from March 2017 to February 2019 in Fujian Maternity and Child Health Hospital (Fuzhou, China) were retrospectively collected, compared, and analyzed. Clinical data of 107 patients with buried penis who were treated using traditional penile fixation technique from February 2014 to February 2017 were chosen for comparison. The results showed that at 6 months and 12 months after surgery, the penile lengths in the modified penile fixation group were longer than those in the traditional penile fixation group (both P < 0.05). The incidence of postoperative skin contracture and penile retraction in the modified penile fixation group was less than that in the traditional penile fixation group (P = 0.034 and P = 0.012, respectively). When the two groups were compared in terms of parents' satisfaction scores, the scores for penile size, penile morphology, and voiding status in the modified penile fixation group were higher than those in the traditional penile fixation group at 2-week, 6-month, and 12-month follow-ups after surgery (all P < 0.05). We concluded that the modified penile fixation technique could effectively reduce the incidence of skin contracture and penile retraction and improve the penile length and satisfaction of patients' parents.

Objective: To explore the composition of intestinal microflora prior to onset of necrotizing enterocolitis (NEC) in very low birth weight preterm infants. Methods: This was a multicenter prospective nested case-control study. A total of 46 very low birth weight preterm infants (birth weight <1 500 g and gestional age <35 weeks) within 24 h of life admitted into Neonatal Intensive Care Unit of Children's Hospital of Soochow University and Suzhou Municipal Hospital from April 20 to November 20, 2018 were enrolled. Baseline clinical data and fecal samples of these infants were collected. The subsequent sampling time points were 1st, 4th and 7th day in the first week of life then once per week consecutively. The endpoint of sampling was NEC occurrence, patient discharge or the 8th week post-discharge, whichever came first. Fecal samples were analyzed by 16 S rDNA high-throughput nucleotide sequencing. The control cases were infants without NEC who were matched to the NEC cases with a ratio of 1∶1. The operational taxonomic units (OTU), sequence number and shannon diversity index of the fecal samples were analyzed. Continuous variables were compared with t-test or non-parametric test, and χ² test or Fisher's exact test was used for categorical variables. Results: There were 23 patients in each group. The gestational age was (29.4±1.8) weeks in NEC group and (29.9±1.6) weeks in control group, including 13 males (57%) and 11 males (48%) in each group, respectively. Species abundance showed that the Firmicutes in both groups decreased temporarily at 7 days of age and then increased with age in control group, but not in NEC group, the Proteobacteria in both groups increased at 7 days of age and then decreased in control group, but kept increasing in NEC group. Regarding the other levels of taxonomy, compared with that of the control group, the NEC group had lower abundance of Proteobacteria, γ-proteobacteria and Enterobacteriaceae at 7 days of age, while higer abundance of Faecalibacterium at 14 days of age, meanwhile, lower Clostridium and Streptococcus at 21 days of age, lower Firmicutes, Clostridia and Clostridium perfringens and higher Proteobacteria and γ-proteobacteria at 28 days of age, these differences were all statistically significant (U=43.00, 43.00, 45.00, 80.00, 74.00, 76.00, 19.00, 8.00, 36.00, 25.00, 25.00,all P<0.05). The shannon index of NEC group was both lower than that of the controls at 21 days of age (2.4 (1.4, 3.0) vs. 3.1 (2.6, 4.0), U=67.00, P=0.027) and 28 days of age (2.4 (1.4, 2.8) vs. 3.9 (3.3, 4.2), U=12.00, P=0.001). Conclusions: The intestinal microflora profile of very low birth weight preterm infants has already changed prior to NEC development. The emergence of differential flora and the reduction of microflora diversity may facilitate early identification and prevention of NEC.

OBJECTIVE: Androgen deficiency is common in aging males and may have unfavourable health consequences. Large-scale studies suggested low testosterone level might increse mortality and morbidity in ageing males. However, young men with low testosterone level might be neglected. Recent studies reported young men with infertility may have reduced testosterone level. To investigate the incidence of androgen deficiency in males with infertility and possible factors affecting the low testosterone level. METHODS: Between January 2011 and December 2012, 407 men with infertility caused by varicocele (VC), obstructive azoospermia (OA) and nonobstructive azoospermia (NOA) in our center were included. The number of men in each group of OA, NOA and VC was 141, 97 and 169, respectively. All the eligible patients underwent a serum testosterone assessment by a single morning blood draw (between 8:00 to noon) to test for concentration of the total testosterone. All serum samples were determined by radioimmunoassay in our andrology laboratory. Androgen deficiency was defined as having a total testosterone level less than 300 ng/dL. RESULTS: The mean age was (30.4±5.8) years. The mean testosterone level was (4.18±1.64) ng/dL (range 0.30 to 11.32 ng/dL). The overall incidence of androgen deficiency was 26.5% (108/407). The incidences of androgen deficiency in NOA, OA and VC groups were 40.2% (39/97), 19.1% (27/141) and 24.9% (42/169), respectively, which were significantly higher in the NOA than in the VC and OA groups (P < 0.001). The incidences had no difference between the VC and OA groups (P=0.229). Univariate analysis revealed the cause of infertility, FSH and the mean testis volume as possible affecting factors for androgen deficiency. However, on multivariate analysis the only cause of infertility was an independent predictor. The incidence of androgen deficiency was the highest in the NOA group [OR 0.492 (95% confidence interval 0.288-0.840)]. CONCLUSION NOA and varicocele might be risk factors of androgen deficiency. Young men with NOA may have a higher possibility of low testosterone level. Testosterone level should be followed up after NOA and varicocele treatment. Androgen deficiency should be assessed in males with infertility in clinical practice.
