Objective:To examine the impact of intrinsic capacity(IC), comorbidity, and their interaction on the occurrence of adverse outcomes in community-dwelling older adults.Methods:This 2-year observational cohort study included 230 residents aged 75 and above who lived in the Beijing Taikang Yanyaun community active area from June to August 2018.The study evaluated the IC scale, Charlson comorbidity index(CCI), and activity of daily living(ADL).In September 2020, adverse outcomes such as functional decline(defined as a decline of at least one point on the ADL scores at 2-year follow-up compared with baseline)and falls were assessed.The structure equation model(SEM)path analysis was employed to examine the direct and indirect effects of IC and CCI on adverse outcomes.Results:Among the 212 older adults who completed a 2-year follow-up, aged 75-93(mean age 83.8±4.4)years, 59.4%(126 cases)were female.Out of these participants, 51.4%(109 cases)experienced functional decline and 33.5%(71 cases)had falls.Path analysis revealed that the direct effects of IC on functional decline and falls were significantly positive, with standardized coefficients of 0.430 and 0.369, respectively.However, the effect of CCI was not found to be significant.The multi-variable Logistic regression model showed that the total effect of IC on functional decline and falls remained significantly positive, with values of 1.184 and 0.915, respectively.CCI acted as a mediating factor, with indirect effects on functional decline and falls accounting for 5.4% and 0.8%, respectively.In terms of the relationship between age and adverse outcomes, the indirect effect of IC was significantly higher than that of CCI(functional decline: 0.192 vs.0.037; falls: 0.158 vs.0.017). Conclusions:The maintenance of IC in the health management of community-dwelling older adults should be given more attention as it can significantly affect the incidence of functional decline and falls.Comorbidity, on the other hand, has a weaker influence.

OBJECTIVE@#To investigate the clinical efficacy and action mechanism of moxibustion combined with western medication for rheumatoid arthritis (RA) with blood stasis obstruction.@*METHODS@#Fifty-six patients of RA with blood stasis obstruction were randomly divided into an observation group and a control group, with 28 patients in each group. The patients in the control group were treated with oral administration of leflunomide tablets and celecoxib capsules, while the patients in the observation group were treated with moxibustion in addition to the treatment used in the control group. Moxibustion was performed at bilateral Zusanli (ST 36), Shenshu (BL 23), Xuehai (SP 10), and ashi points, once every other day, three times a week. The treatment duration for both groups was 12 weeks. The TCM syndrome score, disease activity score-28 (DAS-28), rheumatoid factor (RF), hypersensitive C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR), hemorheological indexes (whole blood viscosity high shear, whole blood viscosity low shear, plasma viscosity), serum calcium ion (Ca2+) level, and platelet count (PLT) were observed before and after treatment, and the clinical efficacy was evaluated after treatment in the two groups.@*RESULTS@#Compared with those before treatment, the TCM syndrome scores, DAS-28 scores, RF, hs-CRP, ESR, whole blood viscosity high shear, whole blood viscosity low shear, plasma viscosity, and PLT were decreased after treatment in both groups (P<0.01), with the observation group showing lower values compared with those in the control group (P<0.05). Compared with those before treatment, the serum Ca2+ levels were increased after treatment in both groups (P<0.01), and the observation group showed a higher increase than that in the control group (P<0.05). The total effective rate was 85.7% (24/28) in the observation group, which was higher than 67.9% (19/28) in the control group (P<0.05).@*CONCLUSION@#Moxibustion combined with western medication could alleviate clinical symptoms in patients with RA of blood stasis obstruction, and its mechanism may be related to the inhibition of platelet activation.

OBJECTIVE@#To observe the effects of moxibustion on the ultrastructure of synovial cells of knee joint and serum cytokines in adjuvant arthritis (AA) rats, and to explore the potential mechanism of moxibustion in treatment of rheumatoid arthritis.@*METHODS@#Forty-five Wistar male rats were randomly divided into a normal group, a model group and a moxibustion group, with 15 rats in each group. In the model group and the moxibustion group, the AA model was replicated under wind, cold and humid environment and by injection with complete freund's adjuvant. In the moxibustion group, moxibustion at "Zusanli" (ST 36) and "Shenshu" (BL 23) was used, 20 min each time, once daily, for consecutive 21 days. In the normal group and the model group, no intervention was processed. The scores of the knee joint swelling degree (JSD) and arthritis index (AI) were compared among groups. The ultrastructure of synovial cells of knee joint were observed under transmission electron microscope (TEM). The levels of serum cytokines such as tumor necrosis factor-α (TNF-α), interieukin (IL)-1β, IL-6 and IL-10 were detected using ELISA method.@*RESULTS@#Compared with the normal group, JSD and AI scores, the levels of TNF-α, IL-1β and IL-6 were increased (P<0.01), while IL-10 was reduced (P<0.01) in the model group after intervention. JSD and AI scores, and the levels of TNF-α, IL-1β and IL-6 were lower (P<0.05, P<0.01), while the level of IL-10 was higher (P<0.01) in the moxibustion group compared with the model group. Compared with the normal group, the ultrastructure of synovial cell was obviously damaged in the model group, and the damage was attenuated in the moxibustion group compared with the model group.@*CONCLUSION@#Moxibustion can reduce the symptoms of arthritis in AA rats, which may be related to the improvement of the ultrastructure of synovial cells and the regulation of cytokines.

Objective:To analyze drug-related problems (DRPs) of hospitalized elderly patients with limited life expectancy.Methods:A total of 261 patients aged ≥ 70 years with limited life expectancy according to the 1-year mortality prediction index, who were admitted in the geriatric ward of Peking Union Medical College Hospital from January 2015 to December 2021 were included. According to Strand system, the categories, medications and interventions of DRPs were analyzed.Results:Among 261 patients, 187 (71.6%) had 672 DRPs. The most common DRPs were related to drug safety, including 271 (40.3%) adverse drug reactions and 149 over dosages (22.2%). A total of 207 drugs were involved in DRPs, and the top 5 classes with higher frequency of DRPs were antiinfectives for systemic use(20.7%,139/672), nervous system drugs(19.4%,130/672), alimentary tract and metabolism drugs(16.5%,111/672), cardiovascular system drugs(16.1%,108/672), and blood and hemopoietic organs drugs(13.7%,92/672). The recommendations were given by pharmacists for all 672 DRPs, and 643 were accepted by physicians (95.7%). The therapy need to be adjusted in 564 recommendations and the medications need to be monitored in 108 recommendations. In recommendations of therapy adjustment, 49.6%(280/564) were related to deprescribing. The deprescribing with higher frequency included antiinfectives for systemic use(29.6%, 83/280), lipid modifying agents(7.9%,22/280) and antithrombotic agents(7.9%,22/280). Patients with severe disability had significantly higher average DRPs(2 vs. 1) and average deprescribing(1 vs. 0) than patients without severe disability( Z=-4.83, Z=-3.61, all P<0.001). Conclusion:Drug safety is the most common DRP in limited life expectancy elderly inpatients, particularly for those with severe disability.

Near-infrared spectroscopy is a device used to determine whether traumatic intracranial hemorrhage has occurred and is primarily used for screening in emergency situations. In this study we examined the applicability of this equipment in postmortem inspection. This study included 124 autopsy cases and 59 postmortem inspection cases performed in the National Forensic Service from July 2017 to October 2018. We carried out the test using Infrascanner Model 2000 (Infrascan Inc.). Autopsy cases were divided into four groups (epidural hemorrhage or subdural hemorrhage group, traumatic subarachnoid hemorrhage or cerebral contusion group, nontraumatic intracerebral hemorrhage group, and control group) and analyzed. There was no difference in the test results according to the presence and type of intracranial hemorrhage. The possibility that variables related to postmortem change affected the test results was considered. In conclusion, this study confirmed that near-infrared spectroscopy is not suitable for the detection of traumatic intracranial hemorrhage in postmortem inspection.

Objective:To investigate the correlation between urinary 8-oxo-7, 8-dihydroguanosine(8-oxo-Gsn)and physical function in community-dwelling elderly people.Methods:A total of 210 community-dwelling elderly people aged 75 years and over were enrolled in this cross-sectional analysis.According to the scores of short physical performance battery(SPPB), subjects were divided into three groups: the high performance group(summary score 10-12), the intermediate performance group(summary score 7-9)and the low performance group(summary score 0-6). All participants received a comprehensive geriatric assessment.Urinary 8-oxo-dGsn, serum high-sensitivity C-reactive protein(hs-CRP)and white blood cell count were measured.The correlation between urinary 8-oxo-Gsn and physical function was analyzed by using Pearson correlation analysis and the ordered Logistic regression model.Results:The scores of activities of daily living(ADL), instrumental activities of daily living(IADL), grip strength and gait speed were lower in the low performance group than in the other two groups( H=47.002, 110.902, F=11.962, 235.952, all P<0.001). Levels of urinary 8-oxo-Gsn and serum hs-CRP were higher in the low performance group than in the other two groups( F=23.780 and 13.259, both P<0.001). There was no significant difference in levels of urinary 8-oxo-dGsn or white blood cell count between the three groups(both P>0.05). Urinary 8-oxo-Gsn was negatively correlated with gait speed, grip strength and SPPB score( r=-0.559, -0.302 and-0.450, all P<0.001)and was positively correlated with the time of five-times-sit-to-stand test( r=0.290, P<0.001). Adjusting for age, gender and Charlson comorbidity index, the ordered Logistic regression analysis showed that elevated levels of urinary 8-oxo-Gsn( OR=1.38, 95% CI: 1.06-1.77, P<0.05)and hs-CRP( OR=1.23, 95% CI: 1.04-1.48, P<0.05)decreased physical function. Conclusions:Urinary 8-oxo-Gsn is independently associated with the decline of physical function in community-dwelling elderly adults, suggesting that the oxidative stress level is increased in the elderly with poor physical function.
摘要
In last few years, therapeutic peptides/proteins are rapidly growing in drug market considering their higher efficiency and lower toxicity than chemical drugs. However, the administration of therapeutic peptides/proteins is mainly limited in parenteral approach. Oral therapy which was hampered by harsh gastrointestinal environment and poorly penetrating epithelial barriers often results in low bioavailability (less than 1%-2%). Therefore, delivery systems that are rationally designed to overcome these challenges in gastrointestinal tract and ameliorate the oral bioavailability of therapeutic peptides/proteins are seriously promising. In this review, we summarized various multifunctional delivery systems, including lipid-based particles, polysaccharide-based particles, inorganic particles, and synthetic multifunctional particles that achieved effective oral delivery of therapeutic peptides/proteins.

摘要
The NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome is the most frequently studied in the central nervous system and has been linked to neuropathic pain. In this study, a post-translational mechanism of microRNA (miR)-186 via regulating the expression of NLRP3 in the complete Freund's adjuvant (CFA)-treated mice was investigated. The injection of CFA was used to induce trigeminal neuropathic pain in mice. miRs microarray chip assay was performed in trigeminal ganglions (TGs). CFA treatment significantly increased the mRNA expression of NLRP3, interleukin (IL)-1β, and IL-18 in TGs compared to the control group. Moreover, 26 miRs were differentially expressed in TGs from trigeminal neuropathic pain mice, and the expression of miR-186 showed the lowest level of all the miRs. Further examination revealed that NLRP3 was a candidate target gene of miR-186. We delivered miR-186 mimics to CFA-treated mice. The head withdrawal thresholds of the CFA-treated mice were significantly increased by miR-186 mimics injection compared with CFA single treatment. The mRNA and protein expression of NLRP3, IL-1β, and IL-18 in TGs from trigeminal neuropathic pain mice were significantly inhibited by miR-186 mimics treatment compared to the CFA group. miR-186 was able to suppress the neuropathic pain via regulating the NLRP3 inflammasome signaling.

Traditional treatments for malignant tumor are far from meeting the clinical demands.Recently,research on anti-tumor targeted drugs has made a significant breakthrough,which brings new hope for the treatment of malignant tumor.Anti-tumor targe-ted drugs can specifically target malignant tumor and directly in-hibit the growth of tumor cells,showing no toxicity to the normal tissues and organs.Herein we reviewed the research progress of small molecular targeted drugs and antibody targeting new drugs.
摘要
The Formosan sika deer (Cervus nippon taiouanus) is an endemic subspecies in Taiwan. The original wild deer has been extinct since the late 1960s. The largest captive population is located at the Taipei Zoo. Except for infectious disease outbreaks, no systemic medical research has been reported for this subspecies. This study was conducted to analyze the medical status of the captive Formosan sika deer population, including the hematological and serum chemistry characteristics. To accomplish this, medical records for 34 Formosan sika deer from January 2003 to January 2014 were acquired and analyzed. The most common illness and cause of death was trauma, followed by gastrointestinal and respiratory disease, respectively. The hematologic and serum chemical values of healthy adults were quite different from those of sika deer (Cervus nippon yesoensis). This study provides a closer medical understanding of this subspecies and the results will facilitate its management.
