Objective:To investigate the status quo of potentially inappropriate medication (PIM) among elderly hypertensive patients in community general practice clinic and related influencing factors.Methods:A total of 767 prescriptions for elderly hypertensive patients in a community health service center in Beijing from October 2020 to August 2021 were reviewed. The prevalence of PIM was assessed based on the criteria of potentially inappropriate medications for older adults in China(2017). Logistic regression analysis was employed to analyze the influencing factors for PIM. Results:The survey showed that 198 elderly patients had PIM with 244 person-doses. The top three drugs with high rate of PIM were benzodiazepine-estazolam (64 person-doses), clopidogrel (53 person-doses) and insulin (35 person-doses). Univariate analysis showed that PIM was significantly associated with types of medication;and underlying diseases hypertension with hyperlipidemia, coronary heart disease, type 2 diabetes, osteoarthritis, upper respiratory tract infection and insomnia (χ 2=82.58, 13.65, 17.74, 7.52, 10.34, 68.19,respectively,all P<0.05). Multivariate logistic regression analysis showed that the types of medication, hypertension complicated with upper respiratory tract infection, and insomnia were independent influencing factors for PIM ( OR=1.55, 2.47, 9.05; P<0.05). Conclusion:The study shows that PIM is more common in elderly hypertensive patients in community general practice clinics,which is associated with types of medication, hypertension complicated with upper respiratory tract infection and insomnia. It is suggested that general practitioner working in community clinics should be aware of PIM, minimize the number of prescription drugs, and choose new drugs or non-drug treatments to reduce the occurrence of PIM.

Objective To evaluate the levels of serum 25 hydroxyvitamin D (25(OH)D), parathyroid hormone(PTH)and osteocalcin,as well as bone mineral density(BMD),in aged men in Beijing, and the relationship among these factors.Methods A total of 668 elderly male patients who were treated at the Beijing Friendship Hospital were evaluated, and their medical data were collected. The serum concentrations of 25(OH)D,PTH,and osteocalcin were measured.Additionally,bone mineral density at the lumbar spine1- 4(L1- 4) and left femoral neck were measured using dual-energy X-ray absorptiometry. Participants were divided into 4 groups by age,3 groups according to BMD,and 4 groups according to serum 25(OH)D levels. The relationship among these factors was investigated. Results The mean serum concentrations of 25(OH)D and PTH were (40.2 ± 17.3) nmol/L and (45.19 ± 15.54) ng/L, respectively. The serum 25(OH)D levels in the group aged≥90 years[(27.1±16.8)nmol/L]was significantly lower compared to that in the other groups. Among different BMD groups, serum 25(OH)D levels reduced gradually, but differences were not significant(P>0.05).Age and PTH levels were not significantly associated with 25(OH) D groups (P>0.05). However, BMD of the femoral neck in the groups with severe [(0.782±0.121)g/m2] and mild[(0.775±0.247)g/m2]vitamin D deficiency were significantly lower than that in the group with normal vitamin D levels [(0.837 ± 0.192) g/m2] (P<0.05). With the increase in vitamin D levels, osteocalcin levels decreased significantly(P<0.05).Conclusion Vitamin D deficiency is highly prevalent among aged men in Beijing and the 25(OH)D levels have some correlation with BMD and osteocalcin.

Parkinson′s disease (PD) is a common neurodegenerative disease. Its main pathological feature is the progressive loss of substantia nigra and other catecholaminergic neurons containing neuromelanin (NM). Therefore, NM may be closely related to the pathogenesis of PD. The content of NM can be detected by NM magnetic sensitive sequence imaging, and then it can be applied to the study of the neuropathological mechanism of NM and PD. This paper focuses on the physiological significance of NM, its role in the pathogenesis of PD and the prospect of NM as a biomarker to assist diagnosis and disease monitoring of PD.

OBJECTIVES:
Ulcerative colitis (UC) is a type of inflammatory bowel disease (IBD) mainly characterized by inflammation, ulceration and erosion of colonic mucosa and submucosa. Transient receptor potential vanilloid 1 (TRPV1) is an important mediator of visceral pain and inflammatory bowel disease. This study aims to investigate the protective effect of water soluble propolis (WSP) on UC colon inflammatory tissue and the role of TRPV1.
METHODS:
Male SD rats were randomly divided into 6 groups (n=8): a normal control (NC) group, an ulcerative colitis model (UC) group, a low-WSP (L-WSP) group, a medium-WSP (M-WSP) group, a high-WSP (H-WSP) group, and a salazosulfapyridine (SASP) group. The rats in the NC group drank water freely, and the other groups drank 4% dextran sulfate sodium (DSS) solution freely for 7 d to replicate the ulcerative colitis model. Based on the successful replication of the UC, the L-WSP, M-WSP, and H-WSP groups were given 50, 100, and 200 mg/kg of water-soluble propolis by gavage for 7 d, and the SASP group was given 100 mg/kg of sulfasalazine by gavage for 7 d. The body weight of rats in each group was measured at the same time every day, the fecal traits and occult blood were observed to record the disease activity index (DAI). After intragastric administration, the animals were sacrificed after fasted 24 h. Serum and colonic tissue were collected, and the changes of MDA, IL-6 and TNF-α were detected. The pathological changes of colon tissues were observed by HE staining, and the expression of TRPV1 in colon tissues was observed by Western blotting, immunohistochemistry, and immunofluorescence.
RESULTS:
The animals in each group that drank DSS freely showed symptoms such as weight loss, decreased appetite, depressed state, and hematochezia, indicating that the model was successfully established. Compared with the NC group, DAI scores of other groups were increased (all P<0.05). MDA, IL-6, TNF-α in serum and colon tissues of the UC group were increased compared with the NC group (all P<0.01), and they were decreased after WSP and SASP treatment (all P<0.01). The results of showed that the colon tissue structure was obviously broken and inflammatory infiltration in the UC group, while the H-WSP group and the SASP group significantly improved the colon tissue and alleviated inflammatory infiltration. The expression of TRPV1 in colon tissues in the UC group was increased compared with the NC group (all P<0.01), and it was decreased after WSP and SASP treatment.
CONCLUSIONS
WSP can alleviate the inflammatory state of ulcerative colitis induced by DSS, which might be related to the inhibition of inflammatory factors release, and down-regulation or desensitization of TRPV1.

Lenvatinib, a second-generation multi-receptor tyrosine kinase inhibitor approved by the FDA for first-line treatment of advanced liver cancer, facing limitations due to drug resistance. Here, we applied a multidimensional, high-throughput screening platform comprising patient-derived resistant liver tumor cells (PDCs), organoids (PDOs), and xenografts (PDXs) to identify drug susceptibilities for conquering lenvatinib resistance in clinically relevant settings. Expansion and passaging of PDCs and PDOs from resistant patient liver tumors retained functional fidelity to lenvatinib treatment, expediting drug repurposing screens. Pharmacological screening identified romidepsin, YM155, apitolisib, NVP-TAE684 and dasatinib as potential antitumor agents in lenvatinib-resistant PDC and PDO models. Notably, romidepsin treatment enhanced antitumor response in syngeneic mouse models by triggering immunogenic tumor cell death and blocking the EGFR signaling pathway. A combination of romidepsin and immunotherapy achieved robust and synergistic antitumor effects against lenvatinib resistance in humanized immunocompetent PDX models. Collectively, our findings suggest that patient-derived liver cancer models effectively recapitulate lenvatinib resistance observed in clinical settings and expedite drug discovery for advanced liver cancer, providing a feasible multidimensional platform for personalized medicine.

Ossifying fibroma (OF) and fibrous dysplasia (FD) are two fibro-osseous lesions with overlapping clinicopathological features, making diagnosis challenging. In this study, we applied a whole-genome shallow sequencing approach to facilitate differential diagnosis via precise profiling of copy number alterations (CNAs) using minute amounts of DNA extracted from morphologically correlated microdissected tissue samples. Freshly frozen tissue specimens from OF (n = 29) and FD (n = 28) patients were obtained for analysis. Lesion fibrous tissues and surrounding normal tissues were obtained by laser capture microdissection (LCM), with ~30-50 cells (5 000-10 000 µm
