Osteoporosis （OP） is a metabolic disorder characterized by microstructural deterioration of bone and increased bone fragility due to reduced bone mass， which can cause the development of bone-related diseases. This condition imposes significant economic and psychological burdens on patients. While modern medicine has extensively researched the pathogenesis of OP， it remains incompletely understood. Current clinical management primarily relies on anti-resorptive drugs and synthetic metabolic agents. However， long-term use of some medications may yield suboptimal therapeutic outcomes and lead to severe adverse reactions. Given the necessity for prolonged or lifelong treatment for OP， there is a critical need to identify highly effective， safe， and cost-effective pharmaceutical interventions. In light of evolving disease management paradigms and recent advancements in OP research， traditional Chinese medicine has demonstrated emerging advantages in addressing this condition. Through literature review， this study delves into the pathogenesis of OP from five perspectives： hormonal dysregulation， autophagy， ferroptosis， oxidative stress， and intestinal flora alteration. Furthermore， it summarizes the therapeutic efficacy and specific mechanisms of traditional Chinese medicine monomers and compound formulas against OP through regulating hormone levels， interfering with autophagy， inhibiting ferroptosis， counteract oxidative stress，and maintain intestinal flora balance. These multifaceted insights are expected to provide theoretical reference and guide future clinical traditional Chinese medicine approaches for preventing and managing OP.

BACKGROUND:The stemness index may be associated with the prognosis and immune infiltration of sarcoma,but the specific regulatory mechanism and characteristic genes have yet to be fully elucidated. OBJECTIVE:To investigate the correlation between stem cells and prognosis as well as immune infiltration in sarcoma employing the gene stemness index model and to identify the ferroptosis signature genes associated with sarcoma stem cells. METHODS:The sarcoma RNA sequencing data and related clinical information were obtained from the Cancer Genome Atlas(TCGA).The sarcoma RNA sequencing data were grouped using the sarcoma stemness index.Survival data were used to analyze prognosis between groups.Differentially expressed genes were obtained for pathway enrichment and immune infiltration analysis.Ferroptosis-related differential genes were used to construct a protein interaction network and analyze prognostic correlation.Rhabdomyosarcoma cell lines were cultured and divided into adherent cell group and stem cell group.The adherent cell group received no intervention,while the stem cell group was treated with serum-free culture to enrich stem cells in rhabdomyosarcoma cells.qRT-PCR was used to evaluate stemness markers,ferroptosis-related genes,and mRNA expression of ferroptosis-related markers in the cells. RESULTS AND CONCLUSION:(1)Patients were divided into high and low stemness index groups based on the median stemness index.The progression-free survival of patients in the high stemness index group was lower than that in the low stemness index group by disease risk prediction,suggesting poor prognosis.(2)According to GO and KEGG analysis,the groups with high and low stemness indices differed from one another.There were differences in immune infiltration between the high and low stemness index groups.Nine of the 23 ferroptosis-related genes in the differential genes have the potential to establish a highly correlated network of protein interactions.Patients with high expression of IDO1,IFNG,and AQP5 have a better prognosis,while those with high expression of CA9 have a poor prognosis.(3)The qRT-PCR results demonstrated a significant upregulation of stem cell-related markers NANOG,SOX2,and OCT4 mRNA expressions in the stem cell group compared to the adherent cell group(P<0.05).Compared to the adherent cell group,the stem cell group exhibited decreased mRNA expression level of ferroptosis-related marker SLC7A11(P<0.05)while showing increased levels of ACSL4,GPX4,FTH1,and COX2(P<0.05).Compared to the adherent cell group,the stem cell group displayed decreased mRNA expression level of differentially expressed gene CA9 alongside elevated levels of IDO1,IFNG,and AQP5(P<0.05).Stem cells were strongly associated with sarcoma survival and ferroptosis by bioinformatics analysis and experimental verification.Sarcoma stem cells have aberrant expression of CA9,IDO1,IFNG,and AQP5,which may serve as new targets for sarcoma therapy as well as diagnostic indicators.

ObjectiveTo establish an adjusted Serfling regression model to estimate the excess cases and the excess epidemic period of hand-foot-mouth disease (HFMD) in Beijing from 2011 to 2019, so as to provide data support and decision-making basis for HFMD prevention and control. MethodsThe weekly number of HFMD cases in Beijing from 2011 to 2019 was utilized for adjusted the Serfling regression model. Then the adjusted model was used to fit the baseline and epidemic threshold of HFMD in Beijing from 2011 to 2019, calculating the excess cases and determining the excess epidemic period. ResultsA total of 279 306 cases of HFMD were reported in Beijing from 2011 to 2019, with the climax of the disease occurring in summer and autumn. After adjusting the fitting R² of the Serfling regression model to 0.773, a total of 10 excess epidemic periods totaling 92 weeks were estimated, mainly occurring in summer. The highest number of excess cases during an excess epidemic period was found in 2014 (1 272 cases, 95%CI: 990‒1 554), accounting for 65.04% of the actual cases (95%CI: 50.62%‒79.46%). ConclusionThe adjusted Serfling regression model fits well and can be utilized for early warning of HFMD and estimating the disease burden caused by HFMD.

To summarise clinical experience of Professor FANG Min in treating chronic spinal disease with tuina therapy based on the principle of "focusing on sinews and fine-regulating bones". It is believed that the key mechanism of chronic spinal disease lies in the imbalance of sinews and bones， with sinews being the first， accordingly， the basic treatment principle of "focusing on sinews and fine-regulating bones" is put forward. Combining with the modern anatomical science and the theory of traditional Chinese medicine acupoints and meridians， the treatment of chronic spinal disease adopts the principles of "causing instability in the first， making adjustments in the reverse direction， then recovering and standing up" and "layering tuina， and combining points， lines and surfaces organically"， which can often achieve a more satisfactory therapeutic effect.

OBJECTIVE To evaluate the clinical value of anlotinib in third-line treatment for patients with advanced non-small cell lung cancer （NSCLC） through real-world data. METHODS Clinical data of patients with advanced NSCLC who received treatment at the First Affiliated Hospital of Anhui University of Chinese Medicine from February 2021 to December 2024 were retrospectively collected. They were divided into anlotinib group （27 cases， receiving anlotinib therapy） and immunotherapy group （22 cases， receiving immunotherapy agents alone or in combination with chemotherapy drugs） according to treatment regimens. The progression-free survival （PFS） and overall survival （OS） of patients were compared between the two groups， and the occurrence of adverse drug reactions during the treatment period was recorded. Using a partitioned survival model， an economic evaluation of the two treatment regimens was conducted with a cost-utility analysis approach from the perspective of the healthcare system. RESULTS The median PFS and OS of patients in the anlotinib group were 5.93 months and 11.27 months， respectively； the median PFS and OS of patients in the immunotherapy group were 5.33 months and 9.77 months， respectively； the difference was not statistically significant （P＞0.05）. There was no statistical difference in the total incidence of adverse drug reactions and grade 3-4 serious adverse drug reactions between the two groups （P＞0.05）. Compared with the immunotherapy group， the incremental cost-effectiveness ratio of the anlotinib group was 1 806 724.60 yuan/quality-adjusted life year （QALY）， which was significantly higher than three times China’s per capita gross domestic product in 2024 （287 247 yuan/QALY）. CONCLUSIONS For third-line treatment of advanced NSCLC patients， the efficacy of anlotinib is no worse than that of immunotherapy alone or in combination with chemotherapy drugs， and the safety of the two groups is comparable. However， anlotinib is not cost-effective.

OBJECTIVE To evaluate the efficacy and safety of three aromatase inhibitors （exemestane， anastrozole， letrozole） for postmenopausal hormone receptor （HR）-positive early breast cancer. METHODS PubMed， the Cochrane Library， Embase， CNKI， Wanfang Data， VIP and SinoMed were searched to collect randomized controlled trials （RCTs） of the above three drugs in the treatment of postmenopausal HR-positive early breast cancer patients. The retrieval time limit was from the establishment of the database to October 25， 2024. After literature screening， data extraction and literature quality evaluation， network meta-analysis was performed by using RevMan 5.3 and Stata 18.0 software. RESULTS A total of 15 RCTs involving 44 055 patients were included. The results of network meta-analysis showed that the objective response rate of letrozole group was significantly higher than anastrozole group （P＜0.05）， and the order of surface under the cumulative ranking curve （SUCRA） from high to low was letrozole （85.6%）＞anastrozole （61.5%）＞exemestane （2.8%）. The disease-free survival rate of anastrozole group was significantly higher than exemestane and placebo groups （P＜0.05）， and the order of SUCRA from high to low was letrozole （85.8%）＞ anastrozole （67.3%）＞exemestane （41.4%）＞placebo （5.5%）. The total incidence of adverse reactions in anastrozole group was significantly higher than letrozole and placebo groups （P＜0.05）， and the order of SUCRA from high to low was exemestane （87.4%）＞letrozole （63.9%）＞anastrozole （47.0%）＞placebo （1.7%）. The results of subgroup analysis according to the course of treatment≥104 weeks were consistent with them. CONCLUSIONS Compared with anastrozole， letrozole has better efficacy and safety in the treatment of postmenopausal HR-positive early breast cancer， and the efficacy of exemestane is limited.

ObjectiveTo establish a rat model of osteoarthritis and study the anti-inflammatory effects and mechanisms of fraxetin. MethodsEighteen 8-week-old male SPF-grade SD rats were randomly divided into three groups: Rats in the blank group received a right articular cavity injection of 50 μL of normal saline for 1 week; the model and intervention groups were injected with monosodium iodoacetate (MIA) into the right joint cavity to induce osteoarthritis, while the intervention group subsequently received fraxetin (5 mg·kg^-1·d^-1) for 1 week. Four weeks after drug intervention, abdominal aortic blood was collected. The animals were then euthanized, and knee joint cartilage were collected. The cartilage samples were stained with hematoxylin-eosin, safranin O-fast green, and toluidine blue for histopathological examination and scoring using the Mankin and OARSI scoring systems. The trabecular bone volume/total volume (Tb.BV/TV), trabecular bone surface density/total volume (Tb.BS/TV), and trabecular number (Tb.N) of each group were compared and analyzed using a micro-CT scanning system. The expression levels of various inflammatory factors [tumor necrosis factor α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6)], and cartilage oligomeric matrix protein (COMP) were measured using enzyme-linked immunosorbent assay (ELISA). The expression levels of mitogen-activated protein kinase p38 (p38 MAPK), phosphorylation-p38 MAPK (p-p38 MAPK), c-Jun N-terminal kinase (JNK), and phosphorylation-JNK (p-JNK) were measured by western blotting. ResultsThe staining of cartilage sections of rat knee joints showed that the articular surface defects in the model group were severe, while the cartilage destruction in the intervention group was relatively reduced. Micro-CT results showed that Tb.BV/TV, Tb.BS/TV and Tb.N in the intervention group were significantly higher than those in the model group (P < 0.05); the Mankin score in the model group was significantly higher than that in the blank group (P < 0.05), the Mankin score in the intervention group was significantly lower than that in the model group (P < 0.05); while the OARSI score in the intervention group was significantly lower than that in the model group (P < 0.05). The results of the enzyme-linked immunosorbent assay showed that the serum levels of TNF-α, IL-1β, IL-6, and COMP in the model group were significantly higher than those in the blank group (all P < 0.05), while those in the intervention group were significantly lower than in the model group (P < 0.05). Western blot results showed that the expression levels of p-p38 MAPK and p-JNK in the knee cartilage tissue were significantly lower in the intervention group than in the model group (both P < 0.05), and significantly higher in the model group than in the blank group (both P < 0.05). ConclusionFraxetin may play a therapeutic role in a monosodium iodoacetate-induced rat model of osteoarthritis through the p38 MAPK pathway.

This paper summarizes Professor WANG Xiuxia's clinical experience in treating hyperprolactinemia using the liver soothing therapy. Professor WANG identifies liver qi stagnation and rebellious chong qi （冲气） as the core pathomechanisms of hyperprolactinemia. Furthermore， liver qi stagnation may transform into fire or lead to pathological changes such as spleen deficiency with phlegm obstruction or kidney deficiency with essence depletion. The treatment strategy centers on soothing the liver， with a modified version of Qinggan Jieyu Decoction （清肝解郁汤） as the base formula. Depending on different syndrome patterns such as liver stagnation transforming into fire， liver stagnation with spleen deficiency， or liver stagnation with kidney deficiency， heat clearing， spleen strengthening， or kidney tonifying herbs are added accordingly. In addition， three paired herb combinations are commonly used for symptom specific treatment， Danggui （Angelica sinensis） with Chuanxiong （Ligusticum chuanxiong）， Zelan （Lycopus lucidus） with Yimucao （Leonurus japonicus） ， and Jiegeng （Platycodon grandiflorus） with Zisu （Perilla frutescens）.

ObjectiveTo systematically evaluate the public health governance capacity of 40 cities in Jiangsu, Zhejiang, and Anhui Provinces, providing a scientific evaluation basis for building a "Healthy Yangtze River Delta". MethodsA comprehensive collection of policy documents, public information reports, and research literature related to public health governance capacity in Jiangsu, Zhejiang, and Anhui Provinces was conducted, totaling 6 920 policy documents, 1 720 information reports, and 1 200 literature pieces. Based on the evaluation standards for an appropriate public health system established by the research team, the basic status of public health governance capacity was assessed to identify the strengths and weaknesses of the 40 cities. ResultsIn 2022, the public health governance capacity score for the 40 cities in Jiangsu, Zhejiang, and Anhui Provinces was (562.5±38.0) points. In terms of specific areas, the emergency response field received the highest score of (791.4±49.7) points, while the chronic disease prevention and control field received the lowest score of (368.2±29.6) points. The Jiangsu-Zhejiang-Anhui region has largely achieved the strategic priority of health, gradually improved public health legal regulations, and established a basic organizational framework with a solid foundation for information and data infrastructure. However, challenges still need to be addressed, such as unstable government funding for public health, unclear departmental responsibilities, and barriers to information interoperability. ConclusionThe public health governance capacity of the 40 cities in Jiangsu, Zhejiang, and Anhui Province has been at a moderate level, but disparities have still existed across regions and fields. In the future, while continuing to deepen existing advantages, it is essential to accurately identify the causes of problems, establish a long-term and stable investment mechanism, enhance information connectivity mechanisms, further clarify departmental responsibilities, and promote the achievement of the "Healthy Yangtze River Delta" goal.
