ObjectiveTo investigate the mechanism by which Anmeidan improves learning and memory in insomnia rats by regulating the cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS)/stimulator of interferon genes (STING) signaling pathway to influence immunoinflammation. MethodsSixty SD rats were randomly divided into a blank group, a model group, a suvorexant group (30 mg·kg-1), and Anmeidan low-, medium-, and high-dose groups (4.55, 9.09, and 18.18 g·kg-1), with 10 rats in each group. The insomnia rat model was induced by intraperitoneal injection of p-chlorophenylalanine (PCPA). Anmeidan decoction and normal saline were administered by gavage for 28 days at the corresponding doses. Morris water maze and new object recognition tests were used to assess learning and memory functions. Hematoxylin-eosin (HE) staining and Nissl staining were performed to observe hippocampal cell morphology. Enzyme-linked immunosorbent assay (ELISA) was used to measure the serum levels of interleukin-1 (IL-1), interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-12 (IL-12), interleukin-18 (IL-18), and tumor necrosis factor-α (TNF-α). Western blot and Real-time quantitative polymerase chain reaction(Real-time PCR) were used to detect the relative protein and mRNA expression levels of hippocampal cGAS and STING. ResultsCompared with the blank group, the 5-HT content in the model group was significantly reduced (P<0.01). The latency to the upper platform and total distance were significantly increased (P<0.05, P<0.01), while the residence time in the target quadrant and the number of platform crossings were significantly reduced (P<0.01), and the relative recognition index for new objects was significantly lower (P<0.01). The morphology and arrangement of hippocampal neurons were loose and disordered, with a decreased number of intracellular Nissl bodies. The relative expression levels of IL-1, IL-1β, IL-6, IL-8, IL-12, IL-18, TNF-α, cGAS, and STING pathway proteins and mRNA were significantly upregulated (P<0.01). Compared with the model group, the latency to the upper platform in the high-dose Anmeidan group was significantly shortened (P<0.05). In the medium- and high-dose Anmeidan groups and the suvorexant group, the residence time in the target quadrant and the number of platform crossings were significantly increased (P<0.01). The total distance traveled was significantly reduced (P<0.01), and the relative recognition index for new objects was significantly increased (P<0.01). The hippocampal neurons were more neatly arranged, and the number of intracellular Nissl bodies increased. The expression of IL-1, IL-1β, IL-6, IL-8, IL-12, IL-18, TNF-α, and cGAS proteins and mRNA in the medium- and high-dose Anmeidan groups was significantly downregulated (P<0.05, P<0.01). ConclusionAnmeidan improves learning and memory in insomnia rats, possibly by suppressing immunoinflammation through inhibition of the cGAS/STING signaling pathway.

ObjectiveTo elucidate the potential mechanisms by which the classic prescription Anmeidan alleviates cognitive impairment in insomnia model rats through metabolic profiling. MethodsA total of 60 SD rats were randomly divided into six groups: blank group, model group, low-, medium-, and high-dose Anmeidan groups, and the Suvorexant group, with 10 rats in each group. Except for the blank group, the insomnia model was established in all other groups via intraperitoneal injection of para-chlorophenylalanine. The Suvorexant group was administered Suvorexant solution (30 mg·kg-1·d-1) by gavage, while the low-, medium-, and high-dose Anmeidan groups received Anmeidan decoction (4.55, 9.09, 18.18 g·kg-1·d-1) by gavage. The blank group received an equivalent volume of normal saline. The open field test was used to assess spatial exploration and anxiety/depressive-like behaviors in rats. Serum levels of epidermal growth factor (EGF), brain-derived neurotrophic factor (BDNF), and vasoactive intestinal peptide (VIP) were measured using enzyme-linked immunosorbent assay (ELISA). Untargeted metabolomics was employed to identify differential metabolites in rat serum, and systematic biological methods were applied to analyze the potential targets and pathways of Anmeidan. ResultsCompared to the blank group, the model group exhibited significant reductions in total distance traveled, average speed, number of entries into the central area, time spent in the central area, and frequency of upright events (P<0.01), along with significant decreases in VIP, EGF, and BDNF levels (P<0.05,P<0.01). A total of 100 differential metabolites were identified between the model and blank groups. Compared to the model group, the low-, medium-, and high-dose Anmeidan groups showed significant increases in total distance traveled, average speed, number of entries into the central area, time spent in the central area, and frequency of upright events (P<0.05,P<0.01), as well as a significant increase in VIP levels (P<0.05,P<0.01). Anmeidan significantly reversed abnormal changes in 67 metabolites compared to the model group. A combined analysis identified 134 potential targets of Anmeidan, with network topology analysis suggesting that Caspase-3, B-cell lymphoma 2 (Bcl-2), nuclear transcription factor-κB (NF-κB), interleukin-1β (IL-1β), interleukin-2 (IL-2), matrix metalloproteinase-9 (MMP-9), and Toll-like receptor 4 (TLR4), among others, may serve as key targets of Anmeidan. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis revealed major enriched pathways, including the cyclic adenosine monophosphate (cAMP) signaling pathway, hypoxia inducible factor-1 (HIF-1) signaling pathway, and IL-17 signaling pathway. ConclusionThis study demonstrates that Anmeidan can recalibrate abnormal metabolic profiles in insomnia model rats to mitigate cognitive impairment, with its mechanisms of action potentially involving the regulation of immune-inflammatory responses, energy metabolism, and apoptosis-related pathways.

Sleep, skin, and health are closely interconnected. Clinically, insomnia has a high incidence and is often accompanied by or secondary to skin aging. The two conditions exhibit "different diseases with the same syndrome", significantly affecting the physical and mental health of the Chinese population. Preventing and treating skin aging by improving insomnia is an important strategy, with the principle of "treating different diseases with the same approach" serving as a crucial therapeutic guideline. However, effective clinical prevention and treatment methods for both conditions remain lacking. Traditional Chinese medicine (TCM) has a profound theoretical foundation and notable efficacy in the concurrent treatment of insomnia and skin aging, yet there are few reports on the etiology, pathogenesis, therapeutic principles, and treatment methods of their shared treatment, warranting further exploration. Based on holistic view and syndrome differentiation and treatment in TCM, this study systematically investigates the theoretical origins of the shared manifestations of insomnia and skin aging from multiple dimensions, including etiology, pathological location, pathogenesis, disease nature, and prevention and treatment strategies. As early as Huangdi's Internal Classic (Huangdi Neijing), it was recognized that mental clarity during the day, sound sleep at night, and firm, healthy skin are key indicators of external health, whereas daytime lethargy, poor sleep quality, and dry, withered skin are prominent signs of aging. Maintaining mental clarity during the day and restful sleep at night is essential for skin integrity and healthy aging. Later medical scholars proposed that the common etiology of insomnia and skin aging lies in "internal-external interactions", with the pathological location involving "the five organ systems". The primary pathogenesis includes "deficiency, fire, stagnation, phlegm, and blood stasis", while the disease nature is often characterized by "a combination of deficiency and excess". Treatment should be guided by syndrome differentiation, following the principle of balancing Yin and Yang. This theoretical exploration enriches and advances TCM understanding of disease onset and prevention, providing theoretical guidance for the clinical prevention and treatment of insomnia-associated skin aging and contributing to the realization of the "Healthy China" initiative.

This study aimed to characterize and identify the non-volatile components in aqueous and ethanolic extracts of the stems and leaves of Rhododendron tomentosum by using sensitive and efficient ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry(UHPLC-Q-TOF-MS) combined with a self-built information database. By comparing with reference compounds, analyzing fragment ion information, searching relevant literature, and using a self-built information database, 118 compounds were identified from the aqueous and ethanolic extracts of R. tomentosum, including 35 flavonoid glycosides, 15 phenolic glycosides, 12 flavonoids, 7 phenolic acids, 7 phenylethanol glycosides, 6 tannins, 6 phospholipids, 5 coumarins, 5 monoterpene glycosides, 6 triterpenes, 3 fatty acids, and 11 other types of compounds. Among them, 102 compounds were reported in R. tomentosum for the first time, and 36 compounds were identified by comparing them with reference compounds. The chemical components in the ethanolic and aqueous extracts of R. tomentosum leaves and stems showed slight differences, with 84 common chemical components accounting for 71.2% of the total 118 compounds. This study systematically characterized and identified the non-volatile chemical components in the ethanolic and aqueous extracts of R. tomentosum for the first time. The findings provide a reference for active ingredient research, quality control, and product development of R. tomentosum.

OBJECTIVE:
To investigate the genetic causal relationship of leukocyte telomere length (LTL) with prostatitis, orchitis and epididymitis by two-sample Mendelian randomization (MR).
METHODS:
Using LTL as the exposure factor and prostatitis, orchitis and epididymitis as outcome factors, we mined the Database of Genome-Wide Association Studies (GWAS). Then, we analyzed the causal relationship of LTL with prostatitis, orchitis and epididymitis by Mendelian randomization using inverse variance weighting (IVW) as the main method and weighted median and MR-Egger regression as auxiliary methods, determined the horizontal multiplicity by MR-Egger intercept test, and conducted sensitivity analysis using the leaving-one-out method.
RESULTS:
A total of 121 related single nucleotide polymorphisms (SNPs) were identified in this study. IVW showed LTL to be a risk factor for prostatitis (OR = 1.383, 95% CI: 1.044-1.832, P = 0.024), and for orchitis and epididymitis as well (OR = 1.770, 95% CI: 1.275-2.456, P = 0.000 6).
CONCLUSION
Genetic evidence from Mendelian randomized analysis indicates that shortening of LTL reduces the risk of prostatitis, orchitis and epididymitis.

OBJECTIVE:
To evaluate the efficacy and safety of denosumab in the treatment of prostate cancer with bone metastases.
METHODS:
Relevant studies were retrieved from PubMed, EMBASE, Cochrane, Web of Science, Sinomed , CNKI and Wanfang databases. The Cochrane risk-of-bias assessment tool was used to evaluate the quality of included studies, and relevant data were extracted. meta-analysis was performed using RevMan 5.4 and RStudio software, and forest plots were generated.
RESULTS:
Six randomized controlled trials (RCTs) were included. Compared with the control group, denosumab significantly reduced the risk of skeletal-related events (HR=0.78, 95% CI: 0.62-0.93). In terms of safety, denosumab did not increase the risk of total adverse events, severe adverse events and the adverse events higher than CTC grade 3.
CONCLUSION
Denosumab can delay the time to first skeletal-related event with good safety. However, due to the limitations of this study, further high-quality, large-sample, multicenter RCTs are needed to confirm these findings.

BACKGROUND:
The use of inserted sham acupuncture as a placebo in randomized controlled trials (RCTs) is controversial, because it may produce specific effects that cause an underestimation of the effect of acupuncture treatment.
OBJECTIVE:
This systematic survey investigates the magnitude of insert-specific effects of sham acupuncture and whether they affect the estimation of acupuncture treatment effects.
SEARCH STRATEGY:
PubMed, Embase and Cochrane Central Register of Controlled Trials were searched to identify acupuncture RCTs from their inception until December 2022.
INCLUSION CRITERIA:
RCTs that evaluated the effects of acupuncture compared to sham acupuncture and no treatment.
DATA EXTRACTION AND ANALYSIS:
The total effect measured for an acupuncture treatment group in RCTs were divided into three components, including the natural history and/or regression to the mean effect (controlled for no-treatment group), the placebo effect, and the specific effect of acupuncture. The first two constituted the contextual effect of acupuncture, which is mimicked by a sham acupuncture treatment group. The proportion of acupuncture total effect size was considered to be 1. The proportion of natural history and/or regression to the mean effect (PNE) and proportional contextual effect (PCE) of included RCTs were pooled using meta-analyses with a random-effect model. The proportion of acupuncture placebo effect was the difference between PCE and PNE in RCTs with non-inserted sham acupuncture. The proportion of insert-specific effect of sham acupuncture (PIES) was obtained by subtracting the proportion of acupuncture placebo effect and PNE from PCE in RCTs with inserted sham acupuncture. The impact of PIES on the estimation of acupuncture's treatment effect was evaluated by quantifying the percentage of RCTs that the effect of outcome changed from no statistical difference to statistical difference after removing PIES in the included studies, and the impact of PIES was externally validated in other acupuncture RCTs with an inserted sham acupuncture group that were not used to calculate PIES.
RESULTS:
This analysis included 32 studies with 5492 patients. The overall PNE was 0.335 (95% confidence interval [CI], 0.255-0.415) and the PCE of acupuncture was 0.639 (95% CI, 0.567-0.710) of acupuncture's total effect. The proportional contribution of the placebo effect to acupuncture's total effect was 0.191, and the PIES was 0.189. When we modeled the exclusion of the insert-specific effect of sham acupuncture, the acupuncture treatment effect changed from no difference to a significant difference in 45.45% of the included RCTs, and in 40.91% of the external validated RCTs.
CONCLUSION
The insert-specific effect of sham acupuncture in RCTs represents 18.90% of acupuncture's total effect and significantly affects the evaluation of the acupuncture treatment effect. More than 40% of RCTs that used inserted sham acupuncture would draw different conclusions if the PIES had been controlled for. Considering the impact of the insert-specific effect of sham acupuncture, caution should be taken when using inserted sham acupuncture placebos in RCTs.

OBJECTIVE:
To explore and quantify the association of hot night exposure during the sperm development period (0-90 lag days) with semen quality.
METHODS:
A total of 6,640 male sperm donors from 6 human sperm banks in China during 2014-2020 were recruited in this multicenter study. Two indices (i.e., hot night excess [HNE] and hot night duration [HND]) were used to estimate the heat intensity and duration during nighttime. Linear mixed models were used to examine the association between hot nights and semen quality parameters.
RESULTS:
The exposure-response relationship revealed that HNE and HND during 0-90 days before semen collection had a significantly inverse association with sperm motility. Specifically, a 1 °C increase in HNE was associated with decreased sperm progressive motility of 0.0090 (95% confidence interval [ CI]: -0.0147, -0.0033) and decreased total motility of 0.0094 (95% CI: -0.0160, -0.0029). HND was significantly associated with reduced sperm progressive motility and total motility of 0.0021 (95% CI: -0.0040, -0.0003) and 0.0023 (95% CI: -0.0043, -0.0002), respectively. Consistent results were observed at different temperature thresholds on hot nights.
CONCLUSION
Our findings highlight the need to mitigate nocturnal heat exposure during spermatogenesis to maintain optimal semen quality.

Abstract
In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.
