ABSTRACT

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.

ABSTRACT

Elderly inpatients with coronavirus disease 2019 (COVID-19) are often at nutritional risk and at higher risk of critical disease. The standardized nutrition treatment could effectively improve the nutritional status, quality of life, and clinical outcomes of COVID-19 patients, and is an important component of the comprehensive management of COVID-19. The individualized nutrition diagnosis, treatment and monitoring should be conducted in compliance to standard procedures of medical nutrition therapy, with consideration of the clinical characteristics of elderly COVID-19 inpatients. The Department of Clinical Nutrition at Peking Union Medical College Hospital has integrated the latest clinical nutrition guidelines and clinical practice of nutrition support of COVID-19, with the aim to provide evidence-based, concise and practical recommendations on nutritional management for elderly inpatients with COVID-19. The recommendations here are to inform effective and standardized nutrition support practice.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Objective@#To evaluate the feasibility and potential value of comprehensive geriatric assessment (CGA) in elderly (≥60 years) patients with newly diagnosed acute myeloid leukemia (AML) in China.@*Methods@#The CGA results of 83 newly diagnosed AML (non-APL) patients from 16 hospitals in Beijing and Tianjin between March 2016 and December 2017 were prospectively collected and analyzed. The clinical data, treatment and follow-up information were also collected.@*Results@#Of 83 newly diagnosed elderly AML patients, 81 patients (97.6%) completed all designated CGA assessment. The median number of impaired scales of the CGA assessment in the studied population was 2(0-6). Sixteen patients (19.3%) showed no impairments according to the geriatric assessment scales implem ented by this study. The distributions of impaired scales were as follows: impairment in ADL, 55.4%; IADL impairment, 42.2%; MNA-SF impairment, 48.2%; cognitive impairment, 15.7%; GDS impairment, 31.7%; HCT-CI impairment, 19.5%, respectively. In patients with "good" ECOG (n=46), the proportion of impairment for each CGA scale ranged from 6.5% to 37.0% and 32 patients (68.9%) had at least one impaired CGA scale. Survival analysis showed that the number of impaired scales of the CGA was significantly correlated with median overall survival (P=0.050).@*Conclusions@#CGA was a tool with feasibility for the comprehensive evaluation in elderly AML patients in China. Combined with age and ECOG, CGA may be more comprehensive in assessing patients’ physical condition.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Objective To analyze the clinical characteristics and prognosis of the overlap syndrome of dementia,depression and delirium coexistence in two or three of them (the 2D's or 3D's) in elderly patients,in order to raise awareness.Methods Clinical data of 16 patients aged >65 years diagnosed with the 2D's or 3D's admitted to Peking Union Medical College Hospital from 2010 to 2014 were analyzed and relevant literatures were reviewed.Results Patients with the 2D's or 3D' s accounted for 10% of the elderly demented patients and 3% of the elderly depressive patients.16 patients [11 females and 5 males,median age 82 years and mean age (80±6) years] were enrolled,with 7 cases of dementia with depression,6 cases of delirium superimposed on dementia,2 cases of the 3D's,and 1 case of coexisting depression and incident delirium.The Charlson comorbidity index of the 16 patients was (3.0± 1.5).(4.0± 1.6) kinds of geriatric syndromes were found,and the most common were falls (62%),sleep disorders (56%),frailty (50%),polypharmacy (43 %),and malnutrition (37%).Disability was identified in 14 (88%) patients on admission.Delirium was observed in 9 patients (56 %),with 7 cases of hyperactive delirium and 2 cases of hypoactive delirium.Coexisting underlying dementia was identified after episodes of delirium in 6 cases.16 patients all received corresponding intervention during hospitalization period.During a mean follow-up period of (15±13) months,62 % of the patients had more impaired physical function (ADL score reduction≥ 1),and 43% of the patients had more impaired cognitive function (MMSE score reduction≥3).Two patients were transferred to long-term care facilities and one patient died during follow-up.The readmission rate was 50% within 1 year after discharge.Conclusions The domestic report of overlap syndrome of dementia,depression and delirium is rare.Patients with the coexistence of the 2D's or 3D's are more commonly combined with geriatric syndromes,which results in further cognitive and physical function impairment with a higher re-admission rate.We should pay attention to the follow-up in elderly patients with delirium for screening dementia.

ABSTRACT

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.

ABSTRACT

The efficacy of chemotherapeutic drug in cancer treatment is often hampered by drug resistance of tumor cells, which is usually caused by abnormal gene expression. RNA interference mediated by siRNA and miRNA can selectively knock down the carcinogenic genes by targeting specific mRNAs. Therefore, combining chemotherapeutic drugs with gene agents could be a promising strategy for cancer therapy. Due to poor stability and solubility associated with gene agents and drugs, suitable protective carriers are needed and have been widely researched for the co-delivery. In this review, we summarize the most commonly used nanocarriers for co-delivery of chemotherapeutic drugs and gene agents, as well as the advances in co-delivery systems.
