ObjectiveBased on traditional quality evaluation of Gardeniae Fructus（GF） recorded in historical materia medica， this study systematically compared the quality differences between wild and cultivated GF from morphological characteristics， microscopic features， and contents of primary and secondary metabolites. MethodsVernier calipers and analytical balances were used to measure the length， diameter and individual fruit weight of wild and cultivated GF， and the aspect ratio was calculated. A colorimeter was used to determine the chromaticity value of wild and cultivated GF， and the paraffin sections of them were prepared by safranin-fast green staining and examined under an optical microscope to observe their microstructure. Subsequently， the contents of water-soluble and alcohol-soluble extracts of wild and cultivated GF were detected by hot immersion method under the general rule 2201 in volume Ⅳ of the 2020 edition of the Pharmacopoeia of the People's Republic of China， the starch content was measured by anthrone colorimetric method， the content of total polysaccharides was determined by phenol-sulfuric acid colorimetric method， the sucrose content was determined by high performance liquid chromatography coupled with evaporative light scattering detection（HPLC-ELSD）， and the contents of representative components in them were measured by ultra-performance liquid chromatography（UPLC）. Finally， correlation analysis was conducted between quality traits and phenotypic traits， combined with multivariate statistical analysis methods such as principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA）， key differential components between wild and cultivated GF were screened. ResultsIn terms of traits， the wild GF fruits were smaller， exhibiting reddish yellow or brownish red hues with significant variation between batches. While the cultivated GF fruits are larger， displaying deeper orange-red or brownish red. The diameter and individual fruit weight of cultivated GF were significantly greater than those of wild GF， while the blue-yellow value（b^*） of wild GF was significantly higher than that of cultivated GF. In the microstructure， the mesocarp of wild GF contained numerous scattered calcium oxalate cluster crystals， while the endocarp contained stone cell class round， polygonal or tangential prolongation， undeveloped seeds were visible within the fruit. In contrast， the mesocarp of cultivated GF contained few calcium oxalate cluster crystals， or some batches exhibited extremely numerous cluster crystals. The stone cells in the endocarp were predominantly round-like， with the innermost layer arranged in a grid pattern. Seeds were basically mature， and only a few immature seeds existed in some batches. Regarding primary metabolite content， wild GF exhibited significantly higher total polysaccharide level than cultivated GF（P<0.01）. In category-specific component content， wild GF exhibited significantly higher levels of total flavonoids and total polyphenols compared to cultivated GF（P<0.01）. Analysis of 12 secondary metabolites revealed that wild GF exhibited significantly higher levels of Shanzhiside， deacetyl asperulosidic acid methyl ester， gardenoside and chlorogenic acid compared to cultivated GF（P<0.01）. Conversely， the contents of genipin 1-gentiobioside， geniposide and genipin were significantly lower in wild GF（P<0.01）. ConclusionThere are significant differences between wild and cultivated GF in terms of traits， microstructure， and contents of primary and secondary metabolites. At present， the quality evaluation system of cultivated GF remains incomplete， and this study provides a reference for guiding the production of high-quality GF medicinal materials.

ObjectiveTo investigate the effects of Chaihu Jia Longgu Mulitang（CJLM） on depression-like behaviors and neuroinflammation in rats subjected to social isolation combined with chronic unpredictable mild stress（CUMS）， and to explore the potential underlying mechanisms. MethodsSixty male SD rats were randomly divided into a normal group， a model group， and low-， medium-， and high-dose CJLM groups（2.89， 5.78， 11.56 g·kg^-1）， as well as a fluoxetine group（10 mg·kg^-1）. Except for the normal group， all other groups were subjected to social isolation combined with CUMS for 63 d. During the first 35 d， depression models were established only， and from day 36 onward， modeling and drug administration were conducted simultaneously for a total intervention period of 28 d. Depression-like behaviors were evaluated using the sucrose preference test， open-field test， and forced swimming test. Hematoxylin-eosin（HE） staining was performed to observe hippocampal histomorphology. Immunohistochemistry（IHC） was used to detect the expression levels of ionized calcium-binding adapter molecule 1（Iba1） and gasdermin D（GSDMD） proteins in the hippocampus. Western blot analysis was employed to determine the protein expression levels of adenosine 5′-monophosphate（AMP）-activated protein kinase（AMPK） and phosphorylated（p）-AMPK， silent information regulator 1（SIRT1）， nuclear factor-κB（NF-κB） and p-NF-κB， NOD-like receptor protein 3（NLRP3）， and Caspase-1 in the hippocampus. Real-time quantitative polymerase chain reaction（Real-time PCR） was used to detect the mRNA expression levels of tumor necrosis factor-α（TNF-α）， interleukin（IL）-6， and IL-1β in the hippocampus. ResultsCompared with the normal group， the model group showed a decreased sucrose preference rate（P<0.01）， reduced total movement distance（P<0.01）， prolonged immobility time（P<0.01）， and decreased central zone residence time（P<0.01） in the open-field test， and increased immobility time in the forced swimming test（P<0.01）. Hippocampal neuronal structure was damaged. The contents of Iba1 and GSDMD in the hippocampus were significantly increased（P<0.01）. The protein expression levels of p-AMPK and SIRT1 in the hippocampus were significantly decreased（P<0.01）， whereas the protein expression levels of p-NF-κB， NLRP3， and Caspase-1 were significantly increased（P<0.01）. The mRNA expression levels of IL-1β， IL-6， and TNF-α in the hippocampus were significantly upregulated（P<0.01）. Compared with the model group， the low-， medium-， and high-dose CJLM groups and the fluoxetine group all were able to reverse depression-like behavioral changes， as evidenced by increased sucrose preference rate， increased total movement distance with shortened immobility time in the open-field test， prolonged central zone residence time， and reduced immobility time in the forced swimming test（P<0.05， P<0.01）. Meanwhile， hippocampal neuronal structural damage was alleviated. In the hippocampus， the expression levels of Iba1 and GSDMD were downregulated， the expression levels of p-AMPK and SIRT1 were upregulated， and the abnormal elevations of p-NF-κB， NLRP3， Caspase-1， as well as IL-1β， IL-6， and TNF-α mRNA were suppressed（P<0.05， P<0.01）. ConclusionCJLM can ameliorate depression-like behaviors in rats subjected to social isolation combined with CUMS and attenuate hippocampal neuroinflammation and pyroptosis， suggesting that its effects may be associated with the regulation of AMPK/SIRT1/NF-κB/NLRP3 signaling pathway.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Objective:To investigate the role of WW domain containing E3 ubiquitin protein ligase 1 (WWP1) in enamel development of mice.Methods:Single-cell RNA sequencing data of incisor tissues of postnatal day 7 (P7) mice and mandibular first molar tooth germs of P3.5 mice were used to analyze the expression of Wwp1 in dental epithelial cells. Immunohistochemistry was performed to observe the distribution and expression levels of WWP1 in the epithelium of mouse incisors and mandibular first molar tooth germs. Wwp1 knockout (Wwp1 KO) mice were generated and collected with their control littermates at P1, P7, three mice per group, as well as at P14, P28, 2 months (2M), and 3M, six mice per group. The enamel volumes of molars and incisors were analyzed using micro-CT. Scanning electron microscopy was employed to examine the enamel cross-sections of Wwp1 KO and control mice. Energy dispersive spectroscopy (EDS) was used to analyze the calcium and phosphorus content of the enamel rod of incisors. Immunofluorescence was performed to detect the expression of amelogenin (AMELX) in the ameloblasts of Wwp1 KO and control mice. Additionally, LS-8 ameloblast-like epithelial cells were cultured, and Wwp1 siRNA or overexpression plasmids were transfected to knock down or overexpress WWP1. The protein levels of AMELX were then assessed by Western blotting.Results:Single-cell sequencing result showed a high Wwp1 mRNA expression level in the epithelial cells of mouse incisors and mandibular molar tooth germs. Immunohistochemistry revealed the expression of WWP1 in presecretory, secretory, transitional, and mature ameloblasts. Wwp1 KO mice exhibited enamel developmental defects. The enamel volumes of molars and incisors in Wwp1 KO mice [(0.155±0.016), (0.300±0.017) μm 3] were reduced by 23.95% ( P<0.001) and 28.31% ( P<0.001) compared with the control group [(0.203±0.062), (0.418±0.023) μm 3] respectively. Scanning electron microscopy showed disorganized enamel structures in Wwp1 KO incisors and molars. EDS results showed the weight percent of calcium in the enamel rod of incisors decreased in Wwp1 KO mice [(20.74±0.91)%] compared with the control group [(30.30±3.83)%] ( P<0.001), and the calcium-to-phosphorus ratio decreased in Wwp1 KO mice (1.93±0.01) compared with the control group (2.02±0.01) ( P<0.001). Immunofluorescence showed weaker AMELX expression in ameloblasts of mandibular first molar tooth germs from P1 and P7 Wwp1 KO mice compared with the control group ( P<0.001, P<0.001). In LS-8 cells, Wwp1 knocked-down led to a decrease of AMELX protein expression, while WWP1 overexpression resulted in an increased AMELX protein level. Conclusions:WWP1 promotes ameloblast differentiation and enamel matrix mineralization, playing a critical role in enamel formation.

Objective:To evaluate the therapeutic effectiveness of adult patients with Kashin-Beck disease (KBD) in Gansu Province, and provide guidance for rational and effective treatment of KBD patients.Methods:The KBD patients who participated in the "2021 Basic Public Health Service Subsidy Key Endemic Disease Prevention and Control Project" in Gansu Province were selected as the research subjects. Gender, age, clinical grading characteristics, and treatment plan selection of all subjects were analyzed, and the treatment effectiveness of KBD patients in different regions was evaluated.Results:A total of 6 711 KBD patients were included in the treatment program, including 3 139 males (46.8%) and 3 572 females (53.2%), 3 157 cases (47.0%) of patients aged 60 and 3 554 cases (53.0%) over 60 years old. There were 3 921, 2 166, and 624 patients with grades Ⅰ, Ⅱ, and Ⅲ, respectively, accounting for 58.4%, 32.3%, and 9.3%, respectively. The gender, age composition, and clinical grading among KBD patients included in different regions were compared, and the differences were statistically significant (χ 2 = 194.34, 47.44, 408.61, P < 0.001). In the distribution of treatment schemes, the number of patients who selected "drug treatment", "drug treatment combined with physical therapy", "drug treatment combined with acupuncture and moxibustion/massage", "drug treatment combined with acupuncture and moxibustion/massage combined with physical therapy", and "other treatment schemes" were 4 084 (60.9%), 726 (10.8%), 672 (10.0%), 443 (6.6%), and 786 (11.7%), respectively. The distribution of treatment plans in different regions was compared, and the difference was statistically significant (χ 2 = 1 088.38, P < 0.001). The total effective rate of KBD patients was 84.5% (5 668/6 711). The total effective rates of KBD patients with different clinical grades were ranked from high to low as grade Ⅲ (87.3%, 545/624), grade Ⅱ (86.4%, 1 871/2 166), and grade Ⅰ (82.9%, 3 252/3 921). The total effective rate of KBD patients with different treatment schemes from high to low was "drug treatment combined with acupuncture and moxibustion/massage combined with physical therapy" (91.0%, 403/443), "drug treatment combined with physical therapy" (87.1%, 632/726), "drug treatment" (86.7%, 3 539/4 084), "drug treatment combined with acupuncture and moxibustion/massage" (82.3%, 553/672), and "other treatment schemes" (68.8%, 541/786). The total effective rate of KBD patients in different regions, from high to low, was as follows: Linxia Hui Autonomous Prefecture (100%, 144/144), Qingyang City (88.7%, 3 562/4 017), Pingliang City (85.0%, 1 327/1 562), Gannan Tibetan Autonomous Prefecture (83.9%, 78/93), Dingxi City (70.9%, 151/213), Tianshui City (62.5%, 125/200), and Longnan City (58.3%, 281/482). The total effective rate of KBD patients in different clinical grades, treatment schemes, and regions was compared, and the differences were statistically significant (χ 2 = 16.95, 181.72, 435.80, P < 0.001). Conclusions:The overall effective rate of treatment for KBD patients in Gansu Province is relatively high, but there are significant differences in therapeutic outcomes among cities (prefectures); it is related to the treatment scheme and the clinical grading of patients. The scheme of "drug treatment combined with acupuncture and moxibustion/massage combined with physical therapy" has better efficacy.

ObjectiveTo investigate the protective effects and mechanisms of Bushen Zhuyun prescription （BSZY） on abortion rats with kidney deficiency-corpus luteum inhibition syndrome. MethodsAn abortion rat model with kidney deficiency-corpus luteum inhibition syndrome was constructed. Pregnant mice aged 8-10 weeks were randomly divided into a control group （Control）， a model group （Model）， low-dose BSZY （BSZY-L）， medium-dose BSZY （BSZY-M）， and high-dose BSZY （BSZY-H） groups （2.57， 5.14， 10.28 g·kg^-¹）， and a Zishen Yutai Pill （ZSYT） group （1.575 g·kg^-¹）. Hematoxylin-eosin （HE） staining was used to evaluate histopathological changes in ovarian and decidual tissue of rats in each group. Enzyme-linked immunosorbent assay （ELISA） was employed to measure levels of estrogen （E₂）， progesterone （P）， luteinizing hormone （LH）， prolactin （PRL）， and follicle-stimulating hormone （FSH） in serum. The candidate targets of BSZY were obtained from the Traditional Chinese Medicine System Pharmacology Platform （TCMSP） and Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine （TCMIP） v2.0 databases， while disease targets for recurrent spontaneous abortion （RSA） were retrieved from GeneCards， DrugBank， Online Mendelian Inheritance in Man （OMIM）， and Therapeutic Target Database （TTD）. The intersection targets were identified by the Venny 2.1.0 platform. Pathway enrichment analysis was conducted based on the Metascape database to predict the potential mechanisms of BSZY. Additionally. Western blot was used to verify the effects of BSZY on the expression of estrogen receptor （ERα）， phosphatidylinositol 3-kinase （PI3K）， and protein kinase B （Akt） and explore its protective mechanism on RSA rats. ResultsCompared with the control group， the model group exhibited significantly decreased uterine， ovarian， and embryonic wet weights （P<0.05， P<0.01）， with an abortion rate of 57.18%. The ovarian tissue showed varying degrees of reduction in primordial follicles， primary follicles， mature follicles， and corpora lutea， along with a large number of atretic follicles. The endometrium was thinner， and decidual tissue exhibited cellular edema and disorganized arrangement. In contrast， compared with the model group， the BSZY groups at all doses and the ZSYT group demonstrated increased uterine， ovarian， and embryonic wet weights， along with a reduced abortion rate. The number of primordial follicles， primary follicles， mature follicles， and corpora lutea increased， while atretic follicles decreased. The endometrium thickened， and decidual tissue displayed normal cellular structure with tight arrangement. Additionally， the model group showed significantly decreased levels of E₂， P， PRL， and FSH in serum （P<0.05， P<0.01）， along with a decreasing trend in LH level. In contrast， the BSZY groups at all doses exhibited significantly elevated levels of E₂， P， LH， PRL， and FSH in serum （P<0.05， P<0.01）. Network pharmacology predictions suggested that BSZY may exert protective effects against abortion in rats by activating the ERα/PI3K/Akt signaling pathway. Western blot results confirmed that BSZY significantly upregulated the expression of ERα， PI3K， and p-Akt proteins （P<0.05， P<0.01）. ConclusionBSZY has a protective effect on the abortion rats with kidney deficiency-corpus luteum inhibition syndrome， possibly by activating the ERα/PI3K/Akt signaling pathway to reduce ovarian apoptosis and regulate endocrine function， thereby lowering the abortion rate.

With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

Obesity is a well-established risk factor for thrombotic events such as venous thromboembolism， and the alterations in pharmacokinetics induced by obesity pose challenges for anticoagulation management. This article systematically reviews the advances of the use of various anticoagulants in obese patients， and finds that the dosage of low-molecular-weight heparin needs to be adjusted according to preventive or therapeutic goals in severely obese patients， the preventive dose may be increased to 40 mg， q12 h or 0.5 mg/（kg·d）， while the therapeutic dose is recommended to be reduced to 0.8 mg/（kg·d）， q12 h. Direct oral anticoagulant drugs are safe and effective for general obese patients； in severely obese patients， standard doses of rivaroxaban or apixaban may be used， warranting cautious application and consideration for therapeutic drug monitoring. In special clinical scenarios such as obesity combined with trauma， pregnancy， advanced age， or bariatric surgery， anticoagulation strategies should be individualized， with close attention to monitoring. Future research should focus on optimizing anticoagulant regimens for special populations and addressing anticoagulation management in obese patients with other embolic diseases.
