The chemical constituents were systematically separated from the roots of Berberis polyantha by various chromatographic methods, including silica gel column chromatography, HP20 column chromatography, polyamide column chromatography, reversed-phase C_(18) column chromatography, and preparative high-performance liquid chromatography. The structures of the compounds were identified by physicochemical properties and spectroscopic techniques(1D NMR, 2D NMR, UV, MS, and CD). Four phenylpropanoids were isolated from the methanol extract of the roots of B. polyantha, and they were identified as(2R)-1-(4-hydroxy-3,5-dimethoxyphenyl)-1-propanone-O-β-D-glucopyranoside(1), methyl 4-hydroxy-3,5-dimethoxybenzoate(2),(+)-syringaresinol(3), and syringaresinol-4-O-β-D-glucopyranoside(4). Compound 1 was a new compound, and other compounds were isolated from this plant for the first time. The anti-inflammatory activity of these compounds was evaluated based on the release of nitric oxide(NO) in the culture of lipopolysaccharide(LPS)-induced RAW264.7 macrophages. At a concentration of 10 μmol·L~(-1), all the four compounds inhibited the LPS-induced release of NO in RAW264.7 cells, demonstrating potential anti-inflammatory properties.

OBJECTIVE: To investigate the effect of innovative perioperative pain management on prostate cancer patients with hematuria undergoing prostatic artery embolization (PAE). METHODS: A total of 60 patients undergoing PAE in the Interventional Therapy Department of General Hospital of Eastern Theater Command from May 2024 to January 2025 were selected by convenience sampling method and randomly divided into the intervention group and the control group, with 30 patients in each group. The control group received traditional pain management of nursing. An innovative perioperative pain management was performed in intervention group including preoperative "body-mind-pain" holistic assessment and preparation, intraoperative humanistic care and real-time support, postoperative multimodal analgesia and rehabilitation, dynamic monitoring and closed-loop feedback. The pain degree after 6 hours, 1 day, 3 days and 1 week of the operation, and the quality of life after 1 week of operation, as well as nursing satisfaction at discharge were compared between the two groups. RESULTS: The VAS scores of the intervention group were significantly lower than those of the control group after 6 hours, 1 day, 3 days and 1 week of operation (P<0.05). One week after the operation, the quality of life in the observation group was higher than that of the control group significantly (P<0.05). The nursing satisfaction of the observation group was significantly higher than that of the control group at discharge(P<0.05). CONCLUSION The application of innovative perioperative pain management can alleviate pain of patients with PAE, which improves the quality of life and nursing satisfaction of patients, and is conducive to the rehabilitation of patients.

OBJECTIVE: Observational studies have found associations between inflammatory bowel disease (IBD) and the risk of dementia, including Alzheimer's dementia (AD) and vascular dementia (VD); however, these findings are inconsistent. It remains unclear whether these associations are causal. METHODS: We conducted a meta-analysis by systematically searching for observational studies on the association between IBD and dementia. Mendelian randomization (MR) analysis based on summary genome-wide association studies (GWASs) was performed. Genetic correlation and Bayesian co-localization analyses were used to provide robust genetic evidence. RESULTS: Ten observational studies involving 80,565,688 participants were included in this meta-analysis. IBD was significantly associated with dementia (risk ratio [ RR] =1.36, 95% CI = 1.04-1.78; I ² = 84.8%) and VD ( RR = 2.60, 95% CI = 1.18-5.70; only one study), but not with AD ( RR = 2.00, 95% CI = 0.96-4.13; I ² = 99.8%). MR analyses did not supported significant causal associations of IBD with dementia (dementia: odds ratio [ OR] = 1.01, 95% CI = 0.98-1.03; AD: OR = 0.98, 95% CI = 0.95-1.01; VD: OR = 1.02, 95% CI = 0.97-1.07). In addition, genetic correlation and co-localization analyses did not reveal any genetic associations between IBD and dementia. CONCLUSION Our study did not provide genetic evidence for a causal association between IBD and dementia risk. The increased risk of dementia observed in observational studies may be attributed to unobserved confounding factors or detection bias.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

OBJECTIVE: To explore the protective effect and mechanism of Kuntai (KT) Capsule on angiotensin II (Ang II)-induced hypertension in ovariectomized (OVX) rats. METHODS: Fifty-four rats were randomly divided into 6 groups according to a random number table, 9 in each group: control, OVX sham+Ang II, OVX, OVX+Ang II, OVX+Ang II +E₂, and OVX+Ang II +KT. OVX rats model was constructed by retroperitoneal bilateral ovariectomy. After 4 weeks of pretreatment with KT Capsule [0.8 g/(kg·d) and 17- β -estradiol (E₂, 1.2 mg/(kg·d)] respectively, Ang II was injected into a micro-osmotic pump with a syringe to establish a hypertensive rat model. Blood pressure of rat tail artery was measured in a wake state of rats using a non-invasive sphygmomanometer. Blood pressure changes were compared between the intervention groups (OVX+Ang II +KT, OVX+Ang II +E₂) and the negative control group (OVX+Ang II). Serum malondialdehyde (MDA) level and superoxide dismutase (SOD) activity were detected respectively. The expressions of oxidative stress-related protein superoxide dismutase2 (SOD2) and anti-thioredoxin (TRX), autophagy marker protein [beclin1, light chain (LC) 3 II/I ratio and autophagy canonical pathway protein phosphatidylinositol 3-kinase (PI3K)/serine/threonine kinase (AKT)-mammalian target of rapamycin (mTOR)] were evaluated by Western blotting. RESULTS: Compared with the OVX+Ang II group, the systolic blood pressure of OVX+Ang II +KT group was significantly lowered (P<0.05) but not the diastolic blood pressure. Besides, SOD2 and TRX protein levels in mycardial tissues were significantly reduced in the OVX+Ang II +KT group compared with the OVX+Ang II group (P<0.05). Oxidative stress serum markers MDA and SOD were down- and up-regulated in the OVX+Ang II +KT group, respectively (P<0.05). Compared with OVX+Ang II group, the levels of cardiac proteins beclin-1 and LC3II/LC3 I in OVX+Ang II +KT group were also up-regulated (P<0.05), and the expression levels of p-PI3K, p-AKT and mTOR protein were down-regulated (P<0.05). CONCLUSION KT could protect blood pressure of Ang II-induced OVX rats by inhibiting oxidative stress and up-regulating protective autophagy.

Resveratrol (RES) can inhibit the growth and proliferation of liver cancer cells. However, its role in the precancerous stage is still unclear. This paper aims to study the effect and mechanism of RES on the precancerous stage of liver cancer in rats induced by diethylinitrosamine (DEN). SD rats were divided into normal control group, RES treatment group, DEN treatment group and RES-DEN treatment group. The results showed that after the rats were treated with DEN for 8 weeks, the total expression level of proliferating cell nuclear antigen (PCNA) of hepatocytes increased to 2-fold (P<0.05), and the expression level of PCNA protein in the nucleus increased to 3-fold (P<0.001). However, the expression levels of total PCNA (P<0.05) and nuclear PCNA protein (P<0.001) in hepatocytes of rats treated with RES-DEN decreased, suggesting that RES could significantly inhibit the liver malignant proliferation of cells. Through non-targeted metabolomics and KEGG metabolic pathway enrichment analysis, the results showed that the level of glycolysis did not increase significantly in the hepatocytes of RES-DEN-treated rats, although the transition from the pentose phosphate pathway to the glycolysis pathway was enhanced when compared with the DEN group rats. This finding suggested that the metabolic pathway of phosphoenolpyruvate-pyruvate-lactate was inhibited. Further verification found that the protein expression levels of key enzymes M2-type pyruvate kinase (PKM2) and lactate dehydrogenase (LDHA) in this metabolic pathway were inhibited (P<0.05). RES can reprogram glucose metabolism and inhibit DEN-induced excessive proliferation of rat hepatocytes in the precancerous stage of liver cancer, providing an experimental basis for RES to prevent liver cancer.

Aim To study the therapeutic effect of 35% and 70% ethanol elution sites of Gardeniae Fructus extract on 2,4,6-trinitrobenzene sulfonic acid (TNBS)/ethanol induced ulcerative colitis (UC) in rats, and to identify the chemical composition of the active elution site using mass spectrometry. Methods The UC model induced by TNBS was used in rats, and the different eluted parts were administered by gavage at a dose of 2. lg/kg for 7 days. Body weight measurement , disease activity index (DAI) score, and pathological score of colon tissues were compared. Myeloperoxidase (MPO) , superoxide dismutase (SOD), malondialdehyde ( MDA ) , nitric oxide ( NO ) , tumor necrosis factor-a (TNF-a) , interleukin in mouse colon tissue -6 (IL-6), interleukin-1 (3 (IL-ip) levels were compared among groups. Liquid-mass spectrometry was used to identify the chemical components of the parts with better efficacy. Results Compared with model group, the weight loss in 35% elution site group was significantly improved, the DAI and histopathology scores were markedly reduced, and the contents of MPO, NO, MDA, TNF-a, IL-6 and IL-1(3 in tissues were apparently reduced. SOD content increased significantly (P <0. 01). A total of 19 chemical components were identified by LC-MS, 11 of which were iri- doids. Conclusions The 35% elution site of Gardeni- a has obvious therapeutic effect on UC rats, and the iridoid component may be the material basis for its function.

The prescription research and clinical application of Wenjingtang were summarized in order to provide reference for the formulation of material standard and the development of compound preparation. By systematically sorting out the relevant ancient medical books and modern literature reports， combined with the relevant policy requirements of the development of compound preparations of famous classical formulas， this paper expounded the existing problems and put forward some suggestions. Wenjingtang is composed of nine herbs， which is derived from Complete Effective Prescriptions for Women's Diseases written by CHEN Zi-ming in Song dynasty. The original medicinal plants and medicinal parts of the formula were basically the same as those recorded in the 2020 edition of Chinese Pharmacopoeia， for example， Paeonia lactiflora was the choice of Paeoniae Radix Alba， Cinnamomi Cortex was selected as Guixin， the rhizoma of Curcuma phaeocaulis was selected as Curcumae Rhizoma. It was suggested that raw products should be selected for decoction pieces and processed according to the methods recorded in the 2020 edition of Chinese Pharmacopoeia. According to the dosage of 1 Liang=40 g， the dosages of Angelicae Sinensis Radix， Chuanxiong Rhizoma， Paeoniae Radix Alba， Cinnamomi Cortex， Moutan Cortex and Curcumae Rhizoma were 20 g， the dosages of Ginseng Radix et Rhizoma， Glycyrrhizae Radix et Rhizoma and Achyranthis Bidentatae Radix were 40 g， the total amount of this formula was 240 g. The 9 kinds of decoction pieces were crushed （particle size<6 mm） separately and mixed， each dose was 20 g， 525 mL of water was added， and then decocted to 280 mL. After filtration， warm medicine was taken for once a day. According to ancient books， Wenjingtang has the functions of activating blood circulation， regulating menstruation，warming meridians and dispersing cold. It is mainly used to treat dysmenorrhea， irregular menstruation and other diseases in modern clinical practice. In addition， it has certain curative effect on endometriosis， pelvic inflammatory disease， acne， eczema and other skin diseases. Through the research， the historical evolution and clinical application of Wenjingtang are fully clarified， which can provide research for the later development and application of this famous classical formula.

OBJECTIVE: To study the effect of functional chewing training (FuCT) on masticatory function, the severity of tongue thrust, and the severity and frequency of drooling in children with cerebral palsy. METHODS: A prospective study was performed for 48 children who were diagnosed with oral motor dysfunction from January 2019 to January 2020, and they were randomly divided into an FuCT group and an oral motor training group, with 24 children in each group. Both groups received FuCT or oral motor training for 12 weeks, and then they were evaluated in terms of the changes in the masticatory function, the severity of tongue thrust, and the severity and frequency of drooling. RESULTS: There were no significant differences between the two groups in the masticatory function, the severity of tongue thrust, and the severity and frequency of drooling before treatment (P>0.05). After the 12-week training, the FuCT group showed significant improvements in the masticatory function and the severity of tongue thrust and drooling (P<0.05), but with no improvement in the frequency of drooling (P>0.05), while the oral motor training group had no improvements in the masticatory function, the severity of tongue thrust, and the severity and frequency of drooling (P>0.05). After the 12-week training, the FuCT group had more significantly improvements in the severity of tongue thrust and the severity and frequency of drooling than the oral motor training group (P<0.05). CONCLUSIONS FuCT can effectively improve the masticatory function, the severity of tongue thrust, and the severity and frequency of drooling in children with cerebral palsy.
