Abstract Frailty is a clinical state characterized by increased vulnerability due to the decline of multiple organ functions. It is clinically manifested as slow movement, reduced activity, low energy level and involuntary weight loss. Frailty heightens the risk of disability, long-term hospitalization and mortality in the elderly when they face stressful events. Early assessment of frailty and personalized interventions can prevent and delay its progression, thereby reducing the occurrence of adverse events. This article reviews the literature on frailty published both domestically and internationally from January 2015 to January 2024. It provides an overview of the tools for assessing frailty in the elderly, such as the Clinical Frailty Scale, Frailty Index, Fried Frailty Phenotype, FRAIL Scale, and biological markers, and the management of frailty, including exercise, nutritional interventions, oral health management, and medication management, so as to provide the evidence for early assessment and intervention of frailty.

Angiotensin II (ANGII) plays an important role in the pathogenesis of atherosclerosis by inducing proliferation of vascular smooth muscle cells (VSMCs). In our study, we observed the effects of valsartan on proliferation of cultured VSMCs treated with or without ANGII by cell counting and methyl thiazolyl tetrazolium (MTT) assay, and detected the expression of mitofusin 2 (Mfn2), a newly discovered cell proliferation inhibitor and a related cell proliferation signaling pathway protein by Western blotting. ANGII at a concentration of 10(-6) mol/L significantly stimulated VSMCs proliferation, down-regulated the expression of Mfn2 and up-regulated the expression of Raf and ERK1/2. Valsartan inhibited such effects of ANGII at concentrations of 10(-5) and 10(-6) mol/L, but not at 10(-7) mol/L. Valsartan had no significant effect on the proliferation of untreated VSMCs. These results suggest that valsartan inhibits ANGII-induced proliferation of VSMCs in vitro via Mfn2-Ras-Raf-ERK/MAPK signaling pathway.

Objective To investigate the therapeutic effects of atorvastatin on pulmonary fibrosis of rats induced by Bleomycin(BLM). Methods Fourty-two female Wistar rats were randomly divided into 7 groups:the control group(group C),the model group which was furtherly divided into group 2-week(M2),4-week(M4),6-week(M6),and atorvastatin-treatment group which was furtherly divided into group 2-week(A2),4-week(A4),6-week(A6). Group M and A were induced to pulmonary fibrosis by the method of BLM endotracheal injection,while group C was injected with saline. On 2nd day,group A were given orally atorvastatin by 10 mg/kg?d. Rats were seperately killed on 2nd,4th and 6th week. After intratracheal injection of BLM,alveolitis and pulmonary fibrosis were evaluated by pathology,hydroxyproline concentration and PaO2. Results The lung coefficient of group M2,M4,A2 and A4 was significantly higher than that of group C. The degree of pulmonary fibrosis in group A4 and A6 was improved as compared with group M4,M6. Alveolitis and pulmonary fibrosis in group A were improved compared with those in group M.Hydroxyproline concentration in group A and M were significantly higher than that in group C. while A4 was lower than M4 (P

Objective To establish the rapid pathogen identification method for HIV and Mycobac-terium tuberculosis (Mtb)co-infection and the assay for the drug susceptibility. Methods Geneprobe and 16S rDNA sequencing were used to differentiate mycobacterium species and modified microscopic observation drug susceptibility (MODS) was used for the drug susceptibility test. The above assays were compared with acid-fast smear, L-J culture and proportional drug susceptibility tests. Results (1) Thirty-four mycobacte-rial isolates were obtained from 112 samples collected from 68 HIV patients. Among these isolates, the strain species were determined by Geneprobe and 16S rDNA sequencing as the followings: 21 Mtb complex, 10 NTM including 5 M.avium complex, 2 M.gordonae, 2 M.kansasii, 1 M.colombiense, and 3 co-infection. (2) The sensitivity of Mtb to rifampicin, ethambutol, isoniazid and streptomycin were 100%, 100%, 76.2%, 90.5% respectively, while the sensitivity of NTM to rifampicin, ethambutol, isoniazid and strepto-mycin were 40%, 60%, 0%, 30% respectively. There is no significant statistic difference between the two methods, MODS and the reference standard, for the drug susceptibility test. (3) Six to eight weeks are nee-ded for the identification of the species of mycobacteria and the drug susceptibility test by using traditional method. In this study, 5-14 d, 6-15 d and 10-14 d are needed for Geneprobe, 16S rDNA sequencing, and MODS respectively. The time for the testing has been dramatically shortened. Conclusion The identifica-tion of mycobacterial species and the drug susceptibility test using clinical samples could be completed within 15 days by using combined Geneprobe, 16S rDNA sequencing and modified MODS. This combined method can be used for the pathogen identification and drug resistant test in HIV patients who are co-infected by my-cobacteria.

Objective To investigate the imaging features of adrenal rest tumor.Methods Twelve patients of adrenal rest tumor proved by surgery or clinical diagnosis were retrospectively analyzed.Among these 12 patients,12 were examined with ultrasound,11 with MR and 1 with CT. MR and CT were performed without and with intravenous injection of contrast material.The imaging features of adrenal rest tumor were retrospectively summarized and the relevant literatures reviewed. Results The adrenal rest tumors were found in testis in 10 of the 12 patients,and in ovaries and broad ligament in the remaining two.The imaging features of the testicular adrenal rest tumor were summarized as following:all patients had bilateral testicular masses without change of the testicular contour. On ultrasonography,the lesions were hypoechoic, with some hyperechoic areas and appeared highly vascularized on Colour Doppler ultrasonography.The masses showed iso-density on plain CT,and avid enhancement on post-contrast CT images.The masses ranging in size from0.7 cm×1.0 cm×2.2 cm to 2.3 cm ×2.7 cm ×2.9 cm with uniform signal intensity,lobulated margin on MRI.They exhibited iso- or slight hyperintensity on T1 WI and hypointensity on T2WI relative to normal testicular parenchyma.The tumors showed intense enhancement on post-contrast MR images. No abnormality was detected with Colour Doppler uhrasonography and MR in 2 patients of adrenal rest tumor in ovaries and broad ligament. Conclusion Combining imaging features with the typical clinical history,the diagnosis of adrenal rest tumor could be suggested pre-operatively.
