OBJECTIVE: To investigate the predictive value of the prognostic nutritional index (PNI) and systemic inflammatory response index (SIRI) for short-term efficacy and prognosis in newly treated patients with peripheral T-cell lymphoma (PTCL). METHODS: The general data, laboratory indicators, disease stage and other clinical data of 91 newly treated PTCL patients admitted to the Affiliated Hospital of Xuzhou Medical University from January 2015 to December 2023 were retrospectively analyzed. The optimal cutoff values for PNI and SIRI were determined using receiver operating characteristic (ROC) curves, and the patients were stratified into groups based on these cutoffs to compare clinical features and short-term efficacy between the different groups. Kaplan-Meier method was used to plot survival curves, and univariate and multivariate analyses were performed to identify the factors affecting overall survival (OS). RESULTS: The optimal cutoff values for PNI and SIRI were 45.30 and 1.74×10⁹/L, respectively. Patients in different PNI groups showed statistically significant differences in age, Ann Arbor stage, lactate dehydrogenase (LDH) level, international prognostic index (IPI), prognostic index for PTCL-not otherwise specified (PIT), pathological subtypes, and complete response (CR) rate (P < 0.05). PTCL patients in different SIRI groups exhibited significant differences in Ann Arbor stage, LDH level, IPI score, PIT score, and CR rate (P < 0.05). Logistic regression analysis showed that age ≥60 years old (OR =2.750), Ann Arbor stage Ⅲ-Ⅳ (OR =5.200), IPI score ≥2 (OR =7.650), low PNI (OR =3.296), and high SIRI (OR =3.130) were independent risk factors affecting treatment efficacy in PTCL patients (P < 0.05). Cox proportional hazards regression model analysis showed that low PNI and elevated β₂-microglobulin (β₂-MG) levels were independent risk factors affecting OS (P < 0.05). CONCLUSION PNI and SIRI have certain application value in evaluating short-term efficacy and prognosis in patients with PTCL. Compared with SIRI, PNI demonstrates greater predictive value for patient prognosis.

Long-term spaceflight,characterized by drastic changes in spatial position,disrupts the Earth's inherent environmental periodic signals,such as the day-night light-dark cycle.This leads to a misalignment between the external environmental cycles and the body's endogenous biological rhythms.The cumulative effect of this persistent"time difference"severely disrupts the core biological pathways that regulate the circadian rhythm.It triggers a series of neuroendocrine and behavioral stress responses,exemplified by sleep-wake disorders,which have become a core medical problem constraining the success of long-term space missions and astronaut health.Traditional Chinese Medicine(TCM)posits that aligning with the rhythmic changes of heaven,earth,day,night,and the four seasons,and maintaining the dynamic balance and harmonious functioning of the body's Yin and Yang vital energies,are fundamental principles for safeguarding vitality and resisting external pathogens and internal injuries.However,in the prolonged weightlessness,confinement,and abnormal lighting environment of deep space flight,the bond between the human body and natural rhythms is forcibly severed.Yin and Yang Qi become difficult to sustain,the mechanisms of ascent,descent,exit,and entry are obstructed,the visceral Qi transformation functions are impaired,and the circulation of Qi and Blood becomes disordered,ultimately leading to the onset of various disorders.This paper,grounded in the TCM temporal medicine perspective of"correspondence between heaven and human"(tian ren xiang ying)and the theories of Yin-Yang and Qi-Blood,meticulously reviews the historical classics and modern research on acupoint intervention strategies for addressing rhythm disorders and harmonizing Yin and Yang.Building upon this foundation,it innovatively proposes and argues for an integrated acupoint prescription strategy:the"Bei Xin Wu Xue"combined with the classic paired points Zhaohai(KI6)-Shenmai(BL62)on the lower limbs to regulate the dynamic balance of the Yin and Yang Heel Vessels(Yin/Yang Qiao Mai),and the classic paired points Taichong(LR3)-Yongquan(KI1)to guide Qi downward.This combination aims to work at multiple levels-"Heart-Brain,Yin-Yang,Liver-Kidney"-to calm the Heart Spirit,clear the Brain Mansion,and tonify the Liver and Kidney.The goal is to restore Yin and Yang Qi to an orderly and coordinated state,thereby assisting the disordered biological rhythm system in regaining homeostasis.This provides a novel TCM-inspired approach of"rhythm regulation and equilibrium restoration"(tiao shi fu heng)to safeguard the long-term in-orbit health of astronauts.

In order to investigate whether the effect of Yuxuebi Tablets on the peripheral and central inflammation resolution of mice with inflammatory pain is related to their regulation of G protein-coupled receptor 37(GPR37), an inflammatory pain model was established by injecting complete Freund's adjuvant(CFA) into the paws of mice, with a sham-operated group receiving a similar volume of normal saline. The mice were assigned randomly to the sham-operated group, model group, ibuprofen group(91 mg·kg~(-1)), and low-, medium-, and high-dose groups of Yuxuebi Tablets(60, 120, and 240 mg·kg~(-1)). The drug was administered orally from days 1 to 19 after modeling. Von Frey method and the hot plate test were used to detect mechanical pain thresholds and heat hyperalgesia. The levels of interleukin-10(IL-10) and transforming growth factor-beta(TGF-β) in the spinal cord were quantified using enzyme-linked immunosorbent assay(ELISA), and the mRNA and protein expression of GPR37 in the spinal cord was measured by real-time quantitative reverse transcription PCR(qRT-PCR) and Western blot. Additionally, immunofluorescence was used to detect the expression of macrosialin antigen(CD68), mannose receptor(MRC1 or CD206), and GPR37 in dorsal root ganglia, as well as the expression of calcium-binding adapter molecule 1(IBA1), CD206, and GPR37 in the dorsal horn of the spinal cord. The results showed that compared with those of the sham-operated group, the mechanical pain thresholds and hot withdrawal latency of the model group significantly declined, and the expression of CD68 in the dorsal root ganglia and the expression of IBA1 in the dorsal horn of the spinal cord significantly increased. The expression of CD206 and GPR37 significantly decreased in the dorsal root ganglion and dorsal horn of the spinal cord, and IL-10 and TGF-β levels in the spinal cord were significantly decreased. Compared with those of the model group, the mechanical pain thresholds and hot withdrawal latency of the high-dose group of Yuxuebi Tablets significantly increased, and the expression of CD68 in the dorsal root ganglion and IBA1 in the dorsal horn of the spinal cord significantly decreased. The expression of CD206 and GPR37 in the dorsal root ganglion and dorsal horn of the spinal cord significantly increased, as well as IL-10 and TGF-β levels in the spinal cord. These findings indicated that Yuxuebi Tablets may reduce macrophage(microglial) infiltration and foster M2 macrophage polarization by enhancing GPR37 expression in the dorsal root ganglia and dorsal horn of the spinal cord of CFA-induced mice, so as to improve IL-10 and TGF-β levels, promote resolution of both peripheral and central inflammation, and play analgesic effects.

Objective : To construct triggering receptor expressed on myeloid cells 2(TREM2) gene knockout(TREM2-/-) mice using CRISPR/Cas9 technology, to breed TREM2-/- mice and to analyze the genotype of TREM2-/- mice. Methods : CRISPR/Cas9 technology was used to selectively knock out exon 2-3 regions of TREM2 gene to construct a TREM2-/- mouse model, and the genetic background of all mice was C57BL/6J. Polymerase chain reaction(PCR) was used to identify the genotype of mice. Quantitative real-time PCR(qPCR) and Western blot were used to detect the expression level of TREM2 in major tissues of mice, and the authenticity and scientific nature of PCR identification results were verified from mRNA level and protein level. According to the sgRNA sequence, the possible off-target sites were predicted on the CCTop website, and the tail DNA of mice was extracted and amplified by PCR and then Sanger sequencing was performed to detect whether there was off-target effect in TREM2-/- mice. Results : TREM2-/- mice were successfully constructed by CRISPR/Cas9 technology, and the mice were genotyped. The results of agarose gel electrophoresis showed that the mouse genotype with only 415 bp band amplified was wild type(WT), the mouse genotype of the 449 bp band amplified only was TREM2-/-, and the mouse genotypes amplified with 415 bp and 449 bp double bands were heterozygous. qPCR results showed that compared with WT mice, the mRNA expression of TREM2 in heart and brain tissues of TREM2-/- mice was down-regulated(P-/- mice was reduced(P-/- mice. Conclusion TREM2-/- mice are successfully constructed and bred, a reliable genotype identification method is established, the genetic stability of the mouse model is verified, which will provide an important genetic animal model for the study of TREM2 gene function.

Xiaoaiping (XAP) Injection demonstrates the anti-prostate cancer (PCa) effects, yet the underlying mechanism remains unclear. This study aims to investigate the impact of XAP on PCa and elucidate its mechanism of action. PCa cell proliferation was evaluated using a cell counting kit-8 (CCK-8) assay. Cell apoptosis was assessed through Hoechst staining and Western blotting assays. Proteomics technology was employed to identify key molecules and significant signaling pathways modulated by XAP in PCa cells. To further validate potential key genes and important pathways, a series of assays were conducted, including acridine orange (AO) staining, transmission electron microscopy, and immunofluorescence assays. The molecular mechanism of XAP against PCa in vivo was examined using a PC3 xenograft mouse model. Results demonstrated that XAP significantly inhibited cell proliferation in multiple PCa cell lines. In C4-2 and prostate cancer cell line-3 (PC3) cells, XAP induced cellular apoptosis, evidenced by reduced B-cell lymphoma 2 (Bcl-2) levels and elevated Bcl-2-associated X (Bax) levels. Proteomic, immunofluorescence, and quantitative reverse transcription-polymerase chain reaction (qRT-PCR) investigations revealed a strong correlation between forkhead box O3a (FoxO3a) autophagic degradation and the anti-PCa action of XAP. XAP hindered autophagy by reducing the expression levels of autophagy-related protein 5 (Atg5)/autophagy-related protein 12 (Atg12) and enhancing FoxO3a expression and nuclear translocation. Furthermore, XAP exhibited potent anti-PCa action in PC3 xenograft mice and triggered FoxO3a nuclear translocation in tumor tissue. These findings suggest that XAP induces PCa apoptosis via inhibition of FoxO3a autophagic degradation, potentially offering a novel perspective on XAP injection as an effective anticancer therapy for PCa.

Third， the “number of service personnel” and “adequacy of service types” in the resource embeddedness dimension， the “entertainment services” and “medical services” in the functional embeddedness dimension， and the “charging standard” and “service response degree” in the operational-mode embeddedness dimension had a greater impact on supply satisfaction in their corresponding dimensions. ConclusionTo develop community-embedded elderly care， it is essential to strengthen the construction of the team of elderly care professionals， enrich the supply content of elderly care services， and increase the development support with the help of resource embeddedness； establish a unified charging system for elderly care， improve the responsiveness of elderly care services， and enhance the development internal driving force based on operational-mode embeddedness； improve the level of integrated medical and elderly care， emphasize the return of the family as the main body， and perfect the development system by using functional embeddedness as a link.

Objective:To evaluate the efficacy and safety of baricitinib combined with ruxolitinib cream in the treatment of progressive nonsegmental vitiligo.Methods:Clinical data were retrospectively collected from patients with progressive nonsegmental vitiligo in Boao Super Hospital. All the patients were treated with oral baricitinib daily (2 mg/day for patients weighing ≤ 50 kg; 4 mg/day for those > 50 kg) in combination with topical application of ruxolitinib cream twice daily for 24 consecutive weeks. Disease severity was assessed using the facial vitiligo area scoring index (F-VASI) and total body VASI (T-VASI) at baseline, week 12, and week 24. Adverse reactions were monitored throughout the treatment course.Results:Six patients with progressive nonsegmental vitiligo were collected, including 3 males and 3 females, aged 26 - 42 years, with the disease duration ranging from 0.5 to 25 years. At week 12, 3 patients achieved a 50% ~ < 75% improvement in facial vitiligo lesions (F-VASI 50), 1 patient achieved F-VASI 75 (75% ~ < 90% improvement), and 1 patient achieved T-VASI 50; at week 24, 4 patients achieved F-VASI 50, 1 patient achieved F-VASI 75, 1 patient achieved F-VASI 90 (≥ 90% improvement), and 3 patients achieved T-VASI 50. During the treatment, upper respiratory infection occurred in 1 patient, acne in 1 patient, pruritus in 2 patients, elevation of total cholesterol levels in 2 patients, and increase of high-density lipoprotein levels in 2 patients. No severe adverse events were observed during the treatment.Conclusion:The combination therapy with baricitinib and ruxolitinib cream may have potential efficacy and safety in the treatment of progressive nonsegmental vitiligo.

Depression is a highly heterogeneous psychiatric disorder with complex pathogenesis influenced by the interplay of biological,psychological,and social-environmental factors.Based on the 2021 edition of the Chinese Guidelines for the Prevention and Treatment of Depressive Disorders,which explicitly identify gender as a significant risk factor for depression onset,this paper systematically reviews the gender-differentiated pathogenesis and therapeutic advances in depression from both traditional Chinese medicine(TCM)and Western medical perspectives.In Western medicine,a large number of studies have demonstrated the sex-specific mechanism of estrogen/testosterone fluctuations and monoamine transmitter system regulation.While in TCM,although the constitution theory proposes that there are significant gender differences in congenital constitution and that qi depression and qi deficiency are associated with susceptibility to depression,current evidence primarily relies on cross-sectional surveys and lacks validation through high-quality RCTs.Compared with Western medicine,the direct research on gender-differentiated antidepressant effects in TCM remains relatively underdeveloped.In future study,it may be possible to deepen and improve the research on anti-depression in TCM from the biological markers of particular constitutions in the gender dimension.This paper advocates establishing a bio-psycho-social integrated intervention model,advancing mechanistic exploration through prospective cohort studies and multi-omics technologies,and promoting precision diagnosis and treatment systems based on gender differences,and to form a three-dimensional diagnosis and treatment and research system that covers biomarkers,social role assessment,and TCM constitution identification,in order to provide a new theoretical framework and a practical pathway for the precise medical treatment of depression.

Objective To establish a method for the simultaneous determination of peimine,peiminine,and hupehenine in Juhong pills,to investigate the raw material usage of Fritillaria thunbergii Miq.,and to preliminarily develop a detection approach for identifying adulteration with Fritillaria hupehensis Hsiao et K.C.Hsia.Methods The high-performance liquid chromatography-triple quadruple mass spectrometry(HPLC-MS/MS)was performed on an Agilent Poroshell 120 SB C18 column(2.1 mm×100 mm,2.7 μm)with a mobile phase consisting of acetonitrile-methanol(1∶1)and 0.1%formic acid under gradient elution.The flow rate was set at 0.3 mL·min-1.The column temperature was maintained at 35℃,and the injection volume was 2 μL.Electrospray ionization(ESI)in positive ion mode and multiple reaction monitoring were employed to quantify the three components in 170 batches of Juhong pills.Simulated positive samples with varying adulteration ratios of Fritillaria hupehensis Hsiao et K.C.Hsia were prepared to establish a simple yet efficient detection limit for adulteration.Results Three components showed good linear correlation within their ranges(r≥0.997 5),and the averaged recoveries ranged from 92.0%-106.2%.A total of 61 batches were suspected of Fritillaria thunbergii Miq.adulteration with Fritillaria hupehensis Hsiao et K.C.Hsia in raw material inputs,with the peimine to peiminine ratio below 1.15.Among these samples,27 batches were large honey-bound pills with hupehenine levels of 2.636-9.939 μg·g-1;34 batches were water-honeyed pills showing significantly higher hupehenine contamination at 6.752-48.137 μg·g-1.Conclusion The established method is simple,reliable,and accurate for the quality control of Fritillaria thunbergii Miq.adulteration in Juhong pills without imposing significant additional costs.
