This study aims to investigate the effect of Chaijin Jieyu Anshen Formula on the neuroinflammation of rats with insomnia complicated with depression through the regulation of triggering receptor expressed on myeloid cells 2(TREM2)/complement protein C1q signaling pathway. Rats were randomly divided into a normal group, a model group, a positive drug group, as well as a high, medium, and low-dose groups of Chaijin Jieyu Anshen Formula, with 10 rats in each group. Except for the normal group, the other groups were injected with p-chlorophenylalanine and exposed to chronic unpredictable mild stress to establish the rat model of insomnia complicated with depression. The sucrose preference experiment, open field experiment, and water maze test were performed to evaluate the depression in rats. Enzyme-linked immunosorbent assay was employed to detect serum 5-hydroxytryptamine(5-HT), dopamine(DA), and norepinephrine(NE) levels. Hematoxylin and eosin staining and Nissl staining were used to observe the damage in nucleus accumbens neurons. Western blot and immunofluorescence were performed to detect TREM2, C1q, postsynaptic density 95(PSD-95), and synaptophysin 1(SYN1) expressions in rat nucleus accumbens, respectively. Golgi-Cox staining was utilized to observe the synaptic spine density of nucleus accumbens neurons. The results show that, compared with the model group, Chaijin Jieyu Anshen Formula can significantly increase the sucrose preference as well as the distance and number of voluntary activities, shorten the immobility time in forced swimming test and the successful incubation period of positioning navigation, and prolong the stay time of space exploration in the target quadrant test. The serum 5-HT, DA, and NE contents in the model group are significantly lower than those in the normal group, with the above contents significantly increased after the intervention of Chaijin Jieyu Anshen Formula. In addition, Chaijin Jieyu Anshen Formula can alleviate pathological damages such as swelling and loose arrangement of tissue cells in the nucleus accumbens, while increasing the Nissl body numbers. Chaijin Jieyu Anshen Formula can improve synaptic damage in the nucleus accumbens and increase the synaptic spine density. Compared to the normal group, the expression of C1q protein was significantly higher in the model group, while the expression of TREM2 protein was significantly lower. Compared to the model group, the intervention with Chaijin Jieyu Anshen Formula significantly downregulated the expression of C1q protein and significantly upregulated the expression of TREM2. Compared with the model group, the PSD-95 and SYN1 fluorescence intensity is significantly increased in the groups receiving different doses of Chaijin Jieyu Anshen Formula. In summary, Chaijin Jieyu Anshen Formula can reduce the C1q protein expression, relieve the TREM2 inhibition, and promote the synapse-related proteins PSD-95 and SNY1 expression. Chaijin Jieyu Anshen Formula improves synaptic injury of the nucleus accumbens neurons, thereby treating insomnia complicated with depression.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Bone is a highly calcified and vascularized tissue. The vascular system plays a vital role in supporting bone growth and repair, such as the provision of nutrients, growth factors, and metabolic waste transfer. Moreover, the additional functions of the bone vasculature, such as the secretion of various factors and the regulation of bone-related signaling pathways, are essential for maintaining bone health. In the bone microenvironment, bone tissue cells play a critical role in regulating angiogenesis, including osteoblasts, bone marrow mesenchymal stem cells (BMSCs), and osteoclasts. Osteogenesis and bone angiogenesis are closely linked. The decrease in osteogenesis and bone angiogenesis caused by aging leads to osteoporosis. Long noncoding RNAs (lncRNAs) are involved in various physiological processes, including osteogenesis and angiogenesis. Recent studies have shown that lncRNAs could mediate the crosstalk between angiogenesis and osteogenesis. However, the mechanism by which lncRNAs regulate angiogenesis‒osteogenesis crosstalk remains unclear. In this review, we describe in detail the ways in which lncRNAs regulate the crosstalk between osteogenesis and angiogenesis to promote bone health, aiming to provide new directions for the study of the mechanism by which lncRNAs regulate bone metabolism.

Sarcopenia is an age-related syndrome characterized by progressive and widespread loss of skeletal muscle mass and/or decline in muscle function.Its incidence increases year by year with aging and is influenced by multiple factors,including genetic background,lifestyle,nutritional status,and chronic diseases.Recent studies have revealed a significant correlation between sarcopenia and chronic coronary syndromes(CCS),not only in terms of the frequency of occurrence but also the se-verity of the conditions.Moreover,sarcopenia and CCS share common pathogenic mechanisms,en-compassing various pathophysiological processes such as chronic inflammation,oxidative stress,apop-tosis,and insulin resistance.This article aimed to review the current research progress on comorbidity relationship between sarcopenia and CCS,explore their shared pathophysiological basis,and discuss their impacts on clinical prognosis.

ObjectiveTriple-negative breast cancer (TNBC) is the breast cancer subtype with the worst prognosis, and lacks effective therapeutic targets. Colony stimulating factors (CSFs) are cytokines that can regulate the production of blood cells and stimulate the growth and development of immune cells, playing an important role in the malignant progression of TNBC. This article aims to construct a novel prognostic model based on the expression of colony stimulating factors-related genes (CRGs), and analyze the sensitivity of TNBC patients to immunotherapy and drug therapy. MethodsWe downloaded CRGs from public databases and screened for differentially expressed CRGs between normal and TNBC tissues in the TCGA-BRCA database. Through LASSO Cox regression analysis, we constructed a prognostic model and stratified TNBC patients into high-risk and low-risk groups based on the colony stimulating factors-related genes risk score (CRRS). We further analyzed the correlation between CRRS and patient prognosis, clinical features, tumor microenvironment (TME) in both high-risk and low-risk groups, and evaluated the relationship between CRRS and sensitivity to immunotherapy and drug therapy. ResultsWe identified 842 differentially expressed CRGs in breast cancer tissues of TNBC patients and selected 13 CRGs for constructing the prognostic model. Kaplan-Meier survival curves, time-dependent receiver operating characteristic curves, and other analyses confirmed that TNBC patients with high CRRS had shorter overall survival, and the predictive ability of CRRS prognostic model was further validated using the GEO dataset. Nomogram combining clinical features confirmed that CRRS was an independent factor for the prognosis of TNBC patients. Moreover, patients in the high-risk group had lower levels of immune infiltration in the TME and were sensitive to chemotherapeutic drugs such as 5-fluorouracil, ipatasertib, and paclitaxel. ConclusionWe have developed a CRRS-based prognostic model composed of 13 differentially expressed CRGs, which may serve as a useful tool for predicting the prognosis of TNBC patients and guiding clinical treatment. Moreover, the key genes within this model may represent potential molecular targets for future therapies of TNBC.

Objective:To explore high-risk sexual behaviors of HIV/AIDS and related factors in young students in Guangzhou.Methods:A cross-sectional survey was conducted in 5 different types of Guangzhou colleges by convenience sampling with minimum number of classes per grade and 600 samples per school from September to November 2021. The R 4.2.2 software was used to consolidate databases. Simultaneously, a logistic regression model and a decision tree algorithm model, stratifying by whether sexual behaviors had occurred before, were constructed. In each layer, the prediction performance of the two models was evaluated through area under receiver operating characteristic and the confusion matrix, and then the model with high prediction performance was retained.Results:A total of 7 346 students were surveyed. The proportion of the respondents reporting sexual experience were 9.08% (667/7 346), in whom 26.24% (175/667) had risky sexual activity in the past year. The decision tree algorithm model performs well in predicting whether high-risk sexual behaviors have occurred in the past year. When the complexity parameter value is 0.018, and nsplit reaches 4, which means there are 5 leaf nodes in the model, the cross error of the tree will be the smallest. The first best grouping variable in the decision tree was whether to use condoms throughout the first sexual behavior. If condoms were used at their sexual debut, but homosexual practices have occurred in the past year, the probability of risky sexual behavior will increase. If homosexual practices have not occurred in the past year, but the age of sexual debut was below 18 years old while the period of HIV education was after high school, the probability of risk sexual behavior will also increase.Conclusions:AIDS-related risky behaviors of young students still deserved attention. The experience of sexual debut and whether AIDS-related health education has been received before the sexual debut were significant predictors for the occurrence of high-risk sexual behavior. The decision tree algorithm model has particular applicability for predicting and screening potential risk populations.

Objective:To investigate the prevalence of enterovirus 71 (EV71) and the genetic characteristics of VP1 region in common hand, foot and mouth disease (HFMD) cases in Shenzhen from 2016 to 2022.Methods:Throat swabs from mild HFMD in Shenzhen sentinel hospitals were collected from 2016 to 2022. A total of 38 EV71-positive samples were screened from these throat swabs and were sequenced. Then, the VP1 sequence of these EV71-positive samples were analyzed for their phylogenetic evolution by bioimformatics software DNAStar and MEGA 6.Results:From 2016 to 2022, the number of EV71 infections among HFMD patients in Shenzhen sentinel hospitals decreased from 136 in 2016 to 0 in 2022. The mumber of EV71 infections in 2018 and 2019 decreased by 96.3%(257/267) compared to that in 2016 and 2017. From 2020 to 2022, the number of EV71 infections decreased to 0. During this period, the EV71 vaccination rate among HFMD patients increased from 6.4% to 39.6%; Evolutionary analysis showed that the nucleotide homology and amino acid homology between 38 EV71 sample strains in Shenzhen from 2016 to 2022 were 91.8%-99.9% and 98.3%-100.0%, all belonging to the C4a subgenotype; Among them, 26 strains wene local epidemic strains, and 11 strains were imported from other provinces, with a close genetic relationship with epidemic strains in Hainan, Yunnan, Sichuan, Tianjin, Henan, Jilin, and other places. One strain from 2017 had the closest genetic relationship with the US epidemic strain OP207969-USA-2017. Further comparing the EV71 epidemic strains in Shenzhen from 2016 to 2022 and EV71 severe strains, it was found that the EV71 strains in Shenzhen carried four amino acid mutation sites related to severe condition, named R22H, K43R, I249V and T289A.Conclusions:The EV71 epidemic strains in Shenzhen from 2016 to 2022 all belong to the C4a subgenotype, and the number of EV71 infection shows a downward trend with the increase of vaccine coverage rate. At the same time, the distribution of EV71 virus strains in Shenzhen shows a significant decrease in local strains and a predominance of imported strains. There are a total of four amino acid mutation sites associated with severe cases in the EV71 sample strains in Shenzhen from 2016 to 2022. Among them, 22R and 289T are located at the N and C ends of VP1, which are related to EV71 adsorption and targeting cells. The 43R site is associated with binding ability to Annexin2 protein, which enhances cell binding ability.

Objective:To explore the clinical application value of rapid next-generation sequencing (NGS) strategy based on targeted amplicon sequencing in the diagnosis of myeloid neoplasms.Methods:In this observational study, both rapid NGS and conventional NGS on the bone marrow or peripheral blood samples of 682 patients were prospectively performed from February 2021 to August 2022 in First Affiliated Hospital of Soochow University. The sequencing results were analyzed using the local Ion Reporter software and our lab′s self-built bioinformatics platform, respectively. The timeliness of the two sequencing platforms was compared, and the Kappa consistency test was used to evaluate the consistency between the two sequencing platforms. Patients aged between 18 and 59 years with newly diagnosed acute myeloid leukemia (AML) underwent screening by rapid NGS combining multiplex RT-PCR and in situ fluorescence hybridization technique within 72 hours, from whom high-risk patients according to European LeukemiaNet (ELN) 2017 were screened for individualized induction therapy.Results:In terms of timeliness, the median time from sample receipt to report issuance were 3 (2, 4) days and 13 (11, 15) days under rapid NGS and conventional NGS testing, respectively, with a statistically significant difference ( Z=?22.636, P<0.001). Among 682 specimens with a total of 1 507 variants, rapid NGS detected a total of 1 499 variants, with a detection rate of 99.5% and 674 cases were accurate, with an accuracy rate of 98.8%; the conventional NGS detected 1 506 variants, with a detection rate of 99.9% and 681 cases were accurate, with an accuracy rate of 99.9%. In 682 specimens, there were 181 negative and 501 positive, in which 8 cases were missed under rapid NGS, and 1 case was missed under conventional NGS. The kappa value was 0.967 by Kappa consistency test, and P<0.001, suggesting good consistency and consistency between the two NGS platforms. From February 2021 to July 2022, 286 patients who were rapidly diagnosed of AML contained 78 patients screened as the ELN 2017 adverse-risk category, including 42 patients enrolled, with age 39 (33, 52) years old. After one cycle of venetoclax combined with decitabine induction therapy, 78.6%(38/42) of the patients achieved composite complete remission. Among the rest 104 additional myeloid neoplasms, rapid NGS detected mutations in 80 patients, with a detection rate of 76.9%, among which 89.0%(215/242) of the variants could serve as the basis for the diagnostic classification, prognostic evaluation, and target therapy of myelodysplastic syndromes (MDS), myeloproliferative neoplasms (MPN), and myelodysplastic/myeloproliferative neoplasms (MDS/MPN). Conclusion:The rapid NGS based on targeted amplicon sequencing is in good consistency with conventional NGS, and shorters the diagnostic time, whose sensitivity and detection range meets the need for diagnostic classification, prognostic stratification, and target therapy of myeloid neoplasms.
